The use of radiation therapy often plays a role in the sole management of squamous cell carcinoma of the oral cavity knee pain treatment physiotherapy purchase ibuprofen 400 mg with mastercard, with or without chemotherapy tennova comprehensive pain treatment center north ibuprofen 600mg with visa, or as an adjunct in the postoperative phase pain treatment in multiple myeloma generic ibuprofen 600 mg visa. Unfortunately best treatment for uti pain effective 400 mg ibuprofen, despite numerous refinements in surgery and radiation therapy pain treatment center clifton springs purchase ibuprofen with a visa, the 5-year survival rate for all patients with squamous cell carcinoma (including all sites and stages) has improved minimally in the past 50 years best pain medication for a uti 600 mg ibuprofen mastercard. Radiotherapy patients require a pretreatment dental consultation regardless of whether they are dentate or edentulous. The attending dentist should have knowledge of radiotherapy volumes, specifically, high-dose volumes. Patients are also educated on the importance of maintaining meticulous dental hygiene, which is essential to minimize the risks of increased rates of dental caries in xerostomic (dry mouth) patients and osteoradionecrosis of the mandible post radiotherapy. Advances in surgical ablation and reconstruction with excellent cosmetic and functional outcomes have led to most institutions adopting primary surgery as standard management of most oral cavity cancers. Primary radiotherapy should be considered for all patients who are not candidates for surgery. This additional margin allows the inclusion of potential local microscopic spread of cancer, day-to-day variation in treatment set-up, patient movement, organ movement. Tumors close to a critical normal structure, such as the spinal cord, can be treated The two treatment portals (anterior oblique and posterior oblique) that encompass the primary lesion and the first-echelon regional lymph nodes are illustrated. Note that the contralateral parotid and the spinal cord are outside of the radiotherapy field. D, Radiation beam orientation for posterior oblique portal on a three-dimensional reconstruction of the patient. Ensuring daily accurate and precise treatment delivery is a critical quality assurance activity in radiotherapy. In addition, daily variation can result from internal motion variation such as swallowing or changes in soft tissues (edema) and tumor (regression) over the course of a treatment period. Normal parotid glands (shaded green) and the spinal cord (shaded red) are also shown. Sample isodoses (bold yellow and light green lines) are shown conforming around the target while limiting radiation dose to the mandible, parotid glands, and spinal cord. Sophisticated three-dimensional treatment delivery image verification systems to minimize patient (and tumor) set up and internal motion variation are now commercially available. Brachytherapy is a treatment method that delivers very high, but localized radiation doses. However, risks of soft tissue necrosis and osteoradionecrosis of the mandible have been well described with this technique. No randomized trials have compared primary radiotherapy with primary surgery for the management of oral cavity carcinomas. Treatment effects on normal organ function as well as cosmesis should be taken into account before therapy is recommended. Relative contraindications for radiotherapy include extensive bone or cartilage invasion, collagen vascular disorders (particularly scleroderma), previous lowdose radiotherapy, and young age. Hyperfractionation is a dose-escalation strategy used to spare late normal tissue toxicity by decreasing the dose per fraction. Acceleration is the delivery of multiple courses of near conventional fraction sizes, but in an overall shorter treatment period. A recent meta-analysis of altered fractionation randomized trials reported a survival benefit of 3. Individual clinical trials have produced conflicting results regarding the benefit of adding chemotherapy to radiotherapy. Despite this, meta-analyses of many randomized clinical trials of radiotherapy combined with neoadjuvant (before radiotherapy), concurrent (during radiotherapy), or adjuvant (after radiotherapy) chemotherapy have shown the most promising results for concurrent chemotherapy. A typical concurrent chemoradiation regimen combines 70 Gy delivered in 2-Gy fractions over 7 weeks with single-agent cisplatin (100 mg/m2) on days 1, 22, and 43 of the radiation schedule. Combined surgery and radiotherapy may improve local-regional control for patients who are candidates for both treatments. Planned combined therapy requires a coordinated multidisciplinary approach between the surgeon and the radiation oncologist. Postoperative radiotherapy is indicated for positive or close surgical resection margins, multiple positive lymph nodes, or extracapsular lymph node extension. Postoperative radiotherapy is also considered for intraoperative tumor rupture or cut-through, intraoperative revision of initially positive margins, presence of perineural invasion, presence of lymphatic or vascular involvement, and preoperative incisional biopsy of the neck. Generally, nerves are intensively affected and skin smears are almost always positive. These are limited in number with an asymmetrical distribution and altered thermal, pain, and tactile sensation. Borderline-Lepromatous (Virchowian) Leprosy A wide number of lesions are present with a range of possible clinical manifestations (infiltrations, papules, plaques, foveae, and nodules) that are common to the Virchowian form. However, with this type there is a tendency to see some delimitation between the lesions and areas of healthy skin. These lesions contain a large number of bacilli and are normally associated with sulfone resistance. It is more frequently seen in Mexico and is characterized by the diffuse infiltration of the skin, altered sensation that starts in the hands and feet, loss of eyebrows, and telangiectasias in the face and torso. As a result, a new species has been proposed under the name Mycobacterium lepromatosis, but many specialists do not yet accept that this is a separate microorganism. The radial, median, facial, trigeminal, and auricular nerves, among others, may also be damaged. Neuropathic pain is often present spontaneously or when the nerve is palpated, either with or without thickening of the nerve. This can evolve to sensory loss, paresthesia, or muscular atrophy in the corresponding area, in addition to autonomic dysfunction and nerve abscess. Extensive lesions tend to be symmetrical, erythematous or hypochromic, infiltrated, and without clear delineation from normal skin areas. There is diffuse infiltration of the face, with auricular appendages affected in the vast majority of cases and bilateral madarosis also common. Often the nasal cavities will be affected and the oropharynges will be full of nasal secretion highly abundant in bacilli. Subsequent nasal dryness can lead to secondary ulceration and infection with possible perforation and destruction of the nasal septum, resulting in what is commonly referred to as saddle nose. Lesions to the palate, lips, gum, and uvula can further compromise the pharynx, nasopharynx, and tonsils. The eyes may show erythema, dryness, dacryocystitis, lagophthalmos, and/or diminished sensation in the cornea. Likewise, iritis and iridocyclitis may be present, so proper intervention is necessary to ensure prevention of early onset of blindness. The testes may also be directly affected by bacilli, as witnessed by atrophy of the testicular parenchyma and diffuse fibrosis with Leprosy Diagnosis the patient is examined to locate any possible skin lesions with diminished sensation and/or areas of sensory alteration that may be due to compromised peripheral nerves. Lighting must be adequate, and it is important to observe the entire body surface moving from head to toe. The histologic examination of a skin biopsy also helps to provide a more precise disease classification and can help to confirm diagnosis in cases that are bacilloscopy negative. In regions with limited access to laboratory resources, clinical diagnosis is sufficient to warrant the beginning of the standard leprosy treatment regimen, keeping in mind that this is the only dermatologic disease with altered sensation in lesions. Available serologic testing does not show sufficient accuracy for disease diagnosis or infection. The use of rifampin once a month was determined for financial reasons, and there is no study comparing this schedule with daily use. Shorter regimens were used but had shown high relapses rate: daily doses of rifampin and ofloxacin (Floxin)1 for 4 weeks; single-dose course of rifampin, ofloxacin and minocycline (Minocin)1 for single-lesion patients. Fluoroquinolones (pefloxacin,2 ofloxacin, and moxifloxacin [Avelox]1), macrolides (clarithromycin [Biaxin]1), and tetracycline (minocycline) are effective against M. Only rifampin, its derivative rifapentine (Priftin),1 and moxifloxacin are bactericidal drugs; all others are bacteriostatic. In cases of intolerance or resistance to dapsone, this can be removed from the drug regimen. Where similar intolerance or resistance is related to rifampin, this should be substituted with a daily dose of 400 mg of ofloxacin. Leprosy Reactions and Control Over the course of this chronic disease, it is common to experience acute inflammatory episodes called leprosy reactions. In patients with borderline-lepromatous leprosy, it is possible to have both reaction types simultaneously. The sensory loss symptomatic of leprosy can also be difficult to determine in children and in other diseases that produce changes in the normal skin characteristics (Table 1). Treatment Leprosy treatment, like tuberculosis treatment, has to deal with bacillar resistance and persistence. Therapy duration has, as a target, the reduction of the number of persistent bacilli that could lead to relapses. In chronic cases and those that are nonresponsive to treatment, it is possible to administer clofazimine along with steroids, at the initial dosage of 100 mg three times per day for a maximum of 12 weeks. This should be reduced to 100 mg twice daily for another 12 weeks and finally 100 mg/day for 12 to 24 weeks. The skin lesions can be discreet and limited in number, pinkish or cyanotic, often very painful, and potentially necrotizing and ulcerative. Treatment is based on a course of corticosteroid therapy appropriate for each patient. New lesions can erupt along with edema in the hands, feet, and face, as well as general systemic symptoms. It is important to begin an immediate intervention given that neuritis is the most common, serious, and potentially disabling clinical manifestation of T1R. The drug of choice for T1R treatment is prednisone (or prednisolone [Millipred]) with a dosage of 1 to 2 mg/kg/day for at least 12 weeks, at which point it can be tapered off until discontinuing medication around the 24th week. Differential Diagnosis between Relapse and Reaction Relapse rates are very low whereas reactions are quite frequent, even after completing treatment. Lesions to the large nerve trunks, such as the ulnar, median, and tibial, cause motor and sensory loss leading to disabilities such as claw hand and footdrop. The absence of sensation in the hands, soles of the feet, and cornea leaves these areas predisposed to common wounds and pressure ulcers. This reality demands that patients take specific care to avoid ulcers and detect them as soon as possible to prevent secondary infection. When deeper, these nodules are more easily palpated than the more visible ones, but will often ulcerate. The systemic impact can produce edema, myalgia, fever, malaise, asthenia, weight loss, cephalalgia, iritis, episcleritis, iridocyclitis, glaucoma, epistaxis, arthralgia, orchiepididymitis with testicular atrophy, glomerulonephritis, chronic renal insufficiency, hepatosplenomegaly, and amyloidosis. The distribution of thalidomide is restricted in some countries due to its teratogenic effects. For this reason, it should be given under strict supervision with proper medical, ethical, and legal measures in place. Patients with early Lyme disease characterized as a solitary erythema migrans lesion can be treated effectively with a 10-day course of doxycycline (Vibramycin). Vaccination for Lyme disease is currently unavailable as a preventive measure for humans. The best preventive measures are represented by avoidance of areas with high tick burden. Randomized clinical trials found no evidence that prolonged antibiotic therapy provided benefit in patients with chronic Lyme disease. Epidemiology Lyme disease, also known as Lyme borreliosis, is a spirochete tickborne illness of public health importance in temperate regions of North America, Europe, and Asia. Among the spirochete genus Borrelia, the most common species associated with this illness is Borrelia burgdorferi sensu lato. This species is further classified into many different genospecies of which at least three are pathogenic to humans: B. All pathogenic spirochetes are transmitted to humans by the hard-bodied ticks of the Ixodes ricinus complex. Hard-bodied Ixodid ticks typically have a 2- to 6-year life cycle with four stages of development: egg, larval stage, nymphal stage, and adult stage. Nymph ticks are most active during the period from late spring (May) to early autumn (September) and predominantly obtain blood meals from mice or voles, such as the whitefooted mouse (Peromyscus leucopus), which serve as a natural reservoir for B. Although deer are not considered competent reservoirs for Borrelia spirochetes, they are important for the life cycle because they represent a sufficient source of blood meal for adult ticks to maintain the tick population. Although ticks may become infected at any active stage of the life cycle, nymphs and adult females are more likely to harbor the spirochete for further transmission to humans. The occurrence of a tick bite and the duration of tick attachment are critical factors affecting the risk of spirochete transmission and onset of illness. Evidence suggests that an infected tick must remain attached for at least 36 to 48 hours during a blood meal in order for B. Although nymphs and adult Ixodid tick species can transmit the bacterium, it is more likely to occur with nymphs. Additionally, the disease is also associated with a slight male predominance and with greater incidence among persons age 5 to 9 years and 55 to 59 years. Risk Factors In the United States, the risk of Lyme disease is highest among persons, particularly males, who reside within those 12 states considered as having high endemic rates. Outdoor occupational activities, such as forestry, agricultural farming, and landscaping, with increased exposure to tick-infested areas are considered strong risk factors. Leisure outdoor activities, such as camping, hunting, fishing, and gardening, also place persons at risk for infection. Clinical Manifestations In general, the clinical manifestations of Lyme disease are similar among the three pathogenic species and follow three wellrecognized clinical stages: early localized disease, early disseminated disease, and late disease. Early Localized Disease Lyme disease typically begins within 7 to 14 days (range of 3 to 30 days) following a tick bite that is associated with prolonged tick attachment (at least 36 hours in the United States).

Early detection lesions (<2 cm) allow for local resection without node dissection pain syndrome treatment order ibuprofen online. Cases presenting late in the course of disease may require radical en-bloc resection of the tumor and surrounding organs pain medication for dogs tramadol generic ibuprofen 400 mg line, known as pelvic exenteration pain treatment sickle cell cheap 400mg ibuprofen fast delivery. Total exenteration refers to removal of the uterus pain treatment non-pharmacological discount ibuprofen 600 mg, tubes advanced pain treatment center chicago buy ibuprofen 600mg, ovaries treatment pain from shingles discount ibuprofen 400 mg on-line, parametrium, bladder, rectum or rectal segment, vagina, urethra, and a portion of the levator muscles. In an anterior exenteration, the rectum is spared, whereas in a posterior exenteration, the bladder and urethra are preserved. Urinary diversion (usually a continent catheterizable pouch) will be provided by the urologist as a portion of the pelvic reconstruction. Physical exam may also reveal ear deformities, umbilical/inguinal hernias, and aniridia. The medial and lateral walls of the ureters are then sutured together in either an interrupted or running fashion. The Y configured ureters are then anastomosed to the end of the small bowel segment used for the reservoir. The condition is often reported with dyspareunia, but not associated with urinary complaints. However, 11% of women with vulvodynia will concomitantly be diagnosed with interstitial cystitis. The following lymphangiographic patterns were found to be useful in assessing metastatic disease: Filling defects, lymph node enlargement and masses, lymphatic obstruction and collateral vessel formation, and an increase or decrease in the number of lymph nodes. Symptoms of interstitial cystitis, painful bladder syndrome and similar diseases in women: A systematic review. This term applies to children with posterior urethral valves in which there is massive reflux into a dysplastic nonfunctioning kidney; 15% of the patients with posterior urethral valves have this syndrome. Some believe that severe unilateral vesicoureteral reflux is protective of the contralateral nonrefluxing kidney. The role of lymphangiography in the diagnosis and treatment of malignant testicular tumors. The distal urethra is mobilized off the corporal bodies, and the spatulated urethral edges are reanastomosed. Unilateral vesicoureteral reflux: Association with protected renal function in patients with posterior urethral valves. Weiss system revisited: A clinicopathologic and immunohistochemical study of 49 adrenocortical tumors. Respiratory infiltrates or sinusitis are commonly the presenting symptoms, as well as constitutional symptoms (weight loss, fever, etc. Renal involvement is usually vasculitis-induced chronic renal failure, but acute fulminant glomerulonephritis and occasional interstitial nephritis can be present. Other urologic manifestations include granulomatous necrotizing prostatitis, urethritis, or epididymoorchitis. Hemorrhagic cystitis is common, but usually iatrogenic secondary to cyclophosphamide treatment. It is used to determine if pelvocaliectasis or hydronephroureterosis seen radiographically represents functional obstruction or anatomic dilation. This is a technically difficult, invasive test, requiring placement of a percutaneous antegrade catheter into the renal pelvis, with simultaneous monitoring of bladder and renal pelvic pressures during set flow rate of 10 mL/min. Elevation of renal pelvic pressure over bladder pressure indicates some degree of renal obstruction. The most recent update adopted the use of the term urothelial instead of transitional to describe urothelium. A Tru-Cut biopsy needle is inserted through the tip of the glans and into the corpora, and a core of tissue is removed. Through the same glans puncture site, the Tru-Cut can be reinserted in order to create 2 fistulas at the end of both corpora. In females, virilization of the molffian system fails to occur, and wolffian vestiges may persist as the epoophoron, Gartner duct, or the appendix vesiculosa, commonly forming paraovarian cysts. In males, virilization of the wolffian duct gives rise to the epididymis, vas deferens, ejaculatory duct and seminal vesicles. The rostral end of the wolffian duct occasionally persists as a vestigial remnant, the appendix epididymis. Remnants of the mesonephric tubules may persist as a cystic structure, the paradidymis. The National Wilms Tumor Staging System is based upon surgical evaluation before chemotherapy. This presentation is consistent with ovarian failure and may be associated with a host of X-chromosome aberrations. Etiologies may be sporadic or inherited, but the condition is rarely linked to other somatic abnormalities. Other clinical manifestations include short stature, episodic metabolic acidosis, and normal intelligence. Risk factors include anemia, hypoalbuminemia, advanced age, male gender, chronic lung disease, malnutrition, wound infection, and emergent procedure. Surgical variables include suture type, use of prosthetic material, incision location, hypothermia, perfusion, and oxygenation. Primary repair of initial dehiscence carries a 56% success rate with sutures and/or retentions, whereas the use of an interposition mesh confers an initial 100% success rate. This disease occurs most commonly in patients older than 50 presenting with xanthoma-like skin nodules and bilateral lower limb bone pain. More disseminated forms of the disease can have renal failure caused by retroperitoneal and perinephric infiltrative or constrictive changes. Patient-related risk factors include advanced age, anatomic urinary anomalies, poor nutrition, tobacco use, corticosteroid use, immunodeficiency, external/indwelling catheters, distant infection, and prolonged hospitalization. Antibiotics should be given within 60 min of procedure start time, and selected based on patient history, as well as anticipated procedure. Physical exam may reveal short stature; small, firm testes; a small- to normal-sized penis; hypospadias; and gynecomastia. Lab investigation reveals high gonadotropin levels and decreased testosterone levels. The progression is very slow, and these patients can expect a normal lifespan; it is essential to distinguish this syndrome from other, often more severe neurologic diseases. Presentation may be insidious, but the Lenk triad (flank pain, palpable mass, and deterioration with hypovolemic shock) has been described in the event of an acute onset. They are infertile (azoospermia), usually are mentally retarded, and have characteristic facies. Treatment is multimodal, using cisplatinum-based combination chemotherapy and radical surgery. The condition is caused by inspissated secretions, causing epididymal obstruction, and treated by vasoepididymostomy; fertility rates remain poor. It is the most common chromosomal aberration among men, with an estimated frequency of 1:500 among newborns. Caused by a nondisjunction of the meiotic chromosomes of the gametes from either parent, affected individuals are tall, with a eunuchoid habitus, small firm testes, and gynecomastia. The diagnosis may be made with a chromatin-positive buccal smear, indicating the presence of an extra X chromosome. Usually, anterior fusion of the valves is not complete; however, some cases exhibit complete anterior fusion and cleft between the folds posteriorly. It follows an autosomal recessive inheritance pattern, with an incidence of 1 in 25,000 to 1 in 50,000 live births. Characteristics include severe developmental delay, sensorineural deafness, renal cortical cysts, retinal dysfunction, hepatomegaly, and characteristic facies (thus, cerebrohepatorenal syndrome). Usually lethal in childhood, rare patients survive into adolescence and adulthood. Positive diagnosis is made by serum assay of very long-chain fatty acids and dihydroxyacetone phosphate acyl transferase. Syndrome characterized by gynecomastia, aspermatogenesis without aleydigism and increased secretion of follicle stimulating hormone. It has the same pathologic characteristics as its counterparts in any other part of the body, and it is managed in the same way. Through an anterior cystotomy, a rectangular area between the distal urethra and trigone is demarcated. Flaps lateral to this are developed and used to tubularize a neourethra over a 10-Fr catheter. Ejaculatory duct ` obstruction caused by a right giant seminal vesicle with an ipsilateral upper urinary tract agenesia: An embryologic malformation. An alternate method of release involves cutting the closed portion of the actuator (zipper teeth) with trauma shears to release the closed portion of the zipper from around the tissue. Mineral oil is used to lubricate the zipper, and then 1 attempt is made to unzip the zipper. If this attempt is unsuccessful, a sturdy wire cutter (diagonal cutter) is used to cut the median bar on the top of the zipper slider, which connects its front and back plates. Then the slider falls off in 2 pieces, and the zipper teeth come apart readily (Image). Being species-specific, the human sperm-zona pelllucida binding requires human oocytes. Different preservation methods are available, such as salt storage, dimethyl sulfoxide freezing, or ultra-low-temperature freezing.

Chemstrip 10 provides 10 tests (specific gravity, pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, and blood). Agents that color the urine (eg, phenazopyridine [Pyridium]) may interfere with the reading. Mix the remaining sediment by flicking it with your finger and pouring or pipetting 1 or 2 drops onto a microscope slide. Casts are usually reported as number per low-power field and tend to collect around the periphery of the coverslip. Eumorphic red cells are typically seen in cases of postrenal, nonglomerular bleeding. Dysmorphic red cells are more likely associated with glomerular causes of bleeding. A shorter time interval can be used (eg, 12 hr), but the formula must be corrected for this change; a 24-hr sample is less prone to collection error. If the values in the previous example were for a 10-yr-old boy who weighed 70 lb (1. Avoid drugs that can interfere with the test, leading to falsely high catecholamines: Tricyclic antidepressants, labetalol, levodopa, methyldopa, sotalol, benzodiazepines, amphetamines, decongestants, and most psychoactive agents. All these drugs should be discontinued 2 wk prior to testing: Normal: Values are variable and depend on the assay method used.

More extensive information on many medications can be found under the substance headings in other chapters. Spotty hyperpigmentation (melasma) may appear on the face, and usually disappears spontaneously after birth. Additionally, pigmentation of the nipples and the areola, the area around the navel, the armpits, and the genital and anal regions is intensified. During the second half of pregnancy, striae distensae appear relatively often on the stomach, the hips, the thighs and the breasts. Soft fibromata appear more frequently during pregnancy, especially in the neck and axillary regions. Blood circulation in the skin is increased; it feels warm, and the vasomotor excitability of the vessels in the face increases. In addition, the veins in the breast and stomach skin are much more visible, and varicosities in the legs and the vulva, as well as hemorrhoids, may appear. Especially in early pregnancy, the secretion of the sebaceous glands can increase significantly. On the other hand, an acute pregnancy acne (acne gravidarum) can occur during the third month. The growth of hair on the head and of nails is generally enhanced during pregnancy. After birth, hair loss often seems quite threatening; however, this synchronal transition from anagen to telogen hair is fully physiologic, and usually returns to normal over the next few months postpartum. This applies especially to skin that has been altered by infection, and to sore areas; this can lead to increased exposure to the system and thus to the fetus. Basically, every external antibiotic therapy must be critically examined from the perspective of whether there is a bacterial infection that might possibly be more effectively treated systemically. In addition, sensibilization and the development of bacteriological resistance need to be considered with topical antibiotic treatment. With acne therapy, the bacteriostatic sodium sulfacetamide, mostly in combination with sulfur preparations, is topically applied. There are no safety data for the application of sodiumsulfacetamide and silversulfadiazine during pregnancy; the latter is used as prophylaxis against infected burns. Twelve pregnant women topically treated with neomycin (seven exposures in the first trimester) were reported. No data are available related to the specific locally-used antibiotics framycetine, meclocycline, mupirocine, nadifloxacine, and tyrothricine. There has been no suspicion of teratogenic effects with any topically used anti-infectives. Local antivirals No risk during pregnancy has been identified for the virostatic acyclovir (see also extensive experience with sytemic use during pregnancy, Chapter 2. There are reports on eight pregnant women with condylomata acuminata who were treated with imiquimode, an immune modulator and virostatic for topical application. Two were exposed during the first trimester; all newborn were healthy (Einarson 2006, Maw 2004). There is insufficient experience available using the virustatics sodium foscarnet, idoxuridine, penciclovir, tromantadine, and vidarabine. Anti-infectives may be used on the skin, the mucosa, and even in the eye and ear for the appropriate indications during pregnancy. For theoretical reasons, the best-tested substances should also be the first choice for topical usage; however, chloramphenicol should not be used. For usage over wide skin areas, preparations should be viewed as critically as systemic usage because of the danger of absorbing larger amounts of the agent. For condylomata acuminata during pregnancy, cryotherapy or trichloroacetic acid are the treatments of choice. Alcohol Pharmacology and toxicology No toxic effects have been observed, as yet, from the local topical use of alcohols during pregnancy. Benzoyl peroxide Pharmacology and toxicology Benzoyl peroxide is used, in particular, for external treatment of acne. Concurrent topical therapy with retinoids increases the absorption of these agents. There are insufficient experimental or epidemiological data for a risk assessment; however, there are also no case reports indicating teratogenic effects. Benzoyl peroxide in therapeutic concentrations may be used topically on a limited area. This should be considered in the interest of the undisturbed thyroid status necessary for central nervous system differentiation. Retrospective evaluation of children born to mothers who applied iodine vaginal douching did not show indications of teratogenic effects (Czeizel 2004). However, this study did not identify the time of exposure or usage during pregnancy. Iodine-containing disinfectants may only be used during pregnancy on small areas for a few days. Solutions of phenol derivatives, such as cresol and thymol, as well as the chlorinated phenol derivatives. They should not be used in a concentration stronger than 2%, and should only be used on intact skin. It is effective as a disinfectant of the vagina and vulva before birth, and for the abdomen before cesarean section (Briggs 2005). In contrast, caution should be exercised during pregnancy with the neurotoxic phenol derivative hexachlorophene, because when larger areas are treated with concentrations of more than 3%, poisoning, with central nervous system symptoms, has been observed in treated patients (Lockhart 1972). In many publications over the last decades, workplace contact with hexachlorophene has been controversially discussed with respect to fetotoxic effects. A Swedish study of medical staff, involving about 3000 pregnant women who were occupationally exposed and 1653 control pregnancies, did not report an increase in perinatal death or congenital malformations (Baltzar 1979). A further retrospective study associated mental retardation in 306 children from women with, among others, hexachlorophene exposure in the last trimester (Roeleveld 1993). Pregnant women should use the other phenol derivatives mentioned, such as chlorhexidine, for disinfecting the skin and mucosa. Mercury compounds Pharmacology and toxicology Mercury can be substantially absorbed from external use, and is a potential developmental toxicant (Lauwerys 1987; see also Chapters 2. However, their accidental limited application does not justify either a pregnancy interruption or additional diagnostic procedures. Other antiseptics Pharmacology and toxicology Quinoline sulfate has been discussed with respect to mutagenic properties (Andersen 2006). In animal studies, there are indications of a carcinogenic activity, and contradictory data on teratogenicity (Aidoo 1990, Au 1978). There have also been no adverse effects described for pyoktanin as a result of use in pregnancy. However, there are no systematic studies on prenatal toxicity for these substances. Short-term topical use of the substances mentioned, over limited areas, is acceptable for relevant indications. Mygind (2002) found no greater risk for developmental disorders, or difference in birth data, in 363 children born to mothers who had used topical glucocorticoids (170 during the first trimester) (see also Chapter 2. There are no systematic studies for bufexamac, which is used widely in dermatology. Furthermore, there are no studies on other topically applied nonsteroid anti-inflammatory substances such as levomenol and benzydamine. There is no objection to topical therapy with glucocorticoids or bufexamac, as long as treatment time is brief and the area covered is moderately sized. Because of their prostaglandin antagonism, nonsteroid anti-inflammatory drugs should be limited to small areas after the thirtieth week of gestation. There is no problem in treatment with astringents during pregnancy, as their absorption is not likely. In addition, it is used intravenously to obliterate varicose veins, for lesions of the mouth mucosa, in vaginal spermicides, and in cosmetics. Polidocanol in combination with benzethonium and carbamide (urea) has been applied in wound therapeutics. No teratogenic action has been observed to date, in either animal or human studies, for this widely used substance. Because of these effects, camphor and other essential oils are included in a large number of hyperemia-causing dermatological products. No teratogenic action has, as yet, been observed in either animal or human studies for topical application. A retrospective study of 23 exposed women revealed nothing notable (Franssen 1999). Experimentally, coal tar products have, to some extent, demonstrated mutagenic or carcinogenic properties, but there has not yet been any indication of this in the longstanding and well-tried use of the group of substances employed therapeutically in humans. There are no systematic studies on prenatal toxicity, but also no indications of teratogenic effects in humans. Coal tar preparations should ideally not be used in pregnancy; however, accidental use does not require any action. Although there are no studies regarding topical use, these exist for systemic use of tacrolimus in transplant medicine (see Chapter 2. Obviously, serum levels after local treatment with tacrolimus are much lower than in transplant patients. Therefore, this substance can be used topically when there are no acceptable alternatives. The use of pimecrolimus is not advised, but if it is used then no invasive prenatal diagnostics are indicated and certainly there is no reason for termination of pregnancy. Systemic effects would not be expected, even in pregnancy, when used for the appropriate indications. Topical use of the keratolytics mentioned above is no cause for concern with pregnant women when the medications are used on limited areas for limited periods of time. Calcipotriol and dithranol Pharmacology and toxicology Calcipotriol is a vitamin D3 derivative. Systematic studies on prenatal toxicity in humans are lacking here, as they are with dithranol. There is no information on the topical use of the vitamin D derivative tacalcitrol during pregnancy. The above-mentioned substances should not be used over large areas, especially in the presence of inflammatory changes in the skin that make absorption more likely. Selenium disulfide Pharmacology and toxicology Selenium disulfide is used as a topical antifungal in the treatment of tinea vesicolor, as a topical keratolytic, and is applied topically to the scalp to control seborrheic dermatitis and dandruff. Azelaic acid is only to be used in pregnancy when absolutely necessary, on small skin surfaces, and preferably not during the first trimester. When used in pregnancy, there is no justification for invasive prenatal diagnostics or termination of pregnancy. When there is an indication for sulfur, it can be used on small skin areas in pregnancy. Resorcin Pharmacology and toxicology Resorcin is an aromatic alcohol that is used in local acne therapy and in the treatment of other dermatoses as a bactericidal, fungicidal, keratolytic, exfoliative, and antipruritic agent, and for seborrheic dermatitis and psoriasis. Topical treatment on a small area with resorcin, when indicated, is acceptable during pregnancy. In synthetic derivate form, they have been used with great success for over 20 years, both externally and systemically, to treat cystic acne. Tretinoin is also licensed as a systemic preparation for treating promyelocytic leukemia.

Alcohol is the most widely used teratogen, and causes birth defects more often than any medication. Refraining from alcohol during pregnancy is the most effective way to prevent birth defects. Owing to the lipid solubility and the rapid and even distribution of ethanol, the concentration in the blood is, for the most part, the same as in the brain. Considerable interindividual variations in ethanol metabolism rate have been reported (Jones 1984). Prenatal damage as a result of chronic alcoholism comes about primarily because of the direct action of ethanol or acetaldehyde on the fetus. Although the damaging effect of alcohol is different in the various phases of pregnancy, it is by no means limited to the first trimester. Acetaldehyde has been discussed as being possibly more relevant than alcohol because its kinetic varies more, depending on individual metabolism, than does the kinetic of alcohol itself. Maternal malnutrition and disturbances of the liver function can also affect fetal development. In most studies, alcohol consumption is expressed as the average amount consumed per day or week, leaving the pattern of alcohol consumption out of consideration. Internationally, different standard sizes are used for the amount of ethanol in one drink. It should, however, be kept in mind that oral alcohol intake is a discrete parameter (a multiple of units) rather than a continuous parameter. If available, information on the influence of the drinking pattern on each effect will be discussed here. This should be taken into account when comparing the results from the epidemiological studies among women and men. Ethanol inhibits the secretion of oxytocin and vasopressin from the posterior pituitary gland. This physiologic effect was used in the 1970s in tocolysis; with high blood levels, after both intravenous and oral administration, ethanol leads to an inhibition of contractions in two-thirds of all pregnant women (Fuchs 1967). There are indications that consumption of less than 10 g/d ethanol might decrease female fertility. For effects on male fertility, only one published study (Hassan 2004) is available in which effects on fertility are described. Based on this study, it can be concluded that there are indications that consumption of less than 10 g/d of ethanol might also decrease male fertility. Spontaneous abortion and fetal death When evaluating the effects of moderate alcohol consumption (by both men and women), before and during pregnancy, on spontaneous abortion and fetal death, it can be concluded that drinking alcoholic 2. Several human studies by Rasch (2003), Kesmodel (2002A, 2002B), Windham (1995, 1992), Armstrong (1992), Kline (1980), and Harlap (1980) have demonstrated this effect in pregnant women drinking an average of at least 10 g/d of ethanol. Drinking less than 10 g/d of ethanol also revealed these effects in some of the studies; however, these data are less consistent. Preterm delivery and length of gestation Consumption of alcoholic beverages during pregnancy might increase the incidence of preterm delivery (birth before 37 weeks of pregnancy) and decrease the length of gestation. Several cohort studies by Parazzini (2003), Kesmodel (2000), Lundsberg (1997), and Sulaiman (1988) demonstrate an increased incidence of preterm delivery and shorter gestational length after drinking more than 17 g/d of ethanol. It has been suggested that this effect is predominantly related to consumption of alcohol in the second and third trimesters of pregnancy (Sulaiman 1988, Lundsberg 1997, Kesmodel 2000). Birth weight, size, and growth the effects on birth weight, size, and growth are among the most studied developmental endpoints caused by ethanol. It might be concluded that the human data concerning the effects of drinking alcohol on fetal growth are not consistent. The studies of Whitehead (2003), Passaro (1996), Ogston (1992), and Marbury (1983) suggest a relationship between alcohol consumption and decreased fetal growth and birth weight. One of the points of discussion is whether or not the diagnosis should include the criterion of chronic alcoholism of the mother. Further, non-specific malformations in the heart, kidney, and limbs (among them camptodactyly, clinodactyly, and hypoplasia of distal phalanges) may occur. In addition, inhibition of intellectual and motor development with permanent retardation has been observed. Other less-specific birth defects are also involved, such as those of the thorax and genitalia, and oral clefts (Jones 1973). There are no convincing indications that consumption levels lower than 60 g/d increase the incidence of individual anomalies. A meta-analysis performed by Testa (2003) confirmed that prenatal exposure to more than 12 g/dof ethanol will result in a lower mental development index in 1-year-old children. Consumption behavior Regular consumption of small amounts With regular consumption of approximately 15 g/d of ethanol during pregnancy, the first concrete statistical effects on mental development are seen. An increase in the risk of spontaneous abortion, especially in the first 10 weeks of pregnancy, as a result of limited alcohol consumption (three or more drinks a week), has been discussed (Windham 1995). A significant difference was found in the length of the newborn children (who were shorter) from mothers who had consumed 120 g/week ethanol, in comparison with non-drinking mothers. This would seem to manifest itself not as a reduction in intelligence, but more likely as behavioral deviations such as distractibility, and a lowered inhibition threshold in preschool and school-aged children. The level of remarkable behavior correlates with the frequency and the quantity of binging (Nulman 2004, 2000). Long-term development Long-term studies over more than 10 years show that the alcoholrelated morphological features disappear or are minimized in most of 520 2. The majority of the children observed in a longterm study attended special educational needs schools (Steinhausen 1995). Additional follow-up studies of 30 children of alcoholics through adulthood have confirmed that permanent mental and psychiatric developmental disorders must be expected. It is likely that more than a few children of alcoholics will be overlooked at birth, and that their development will not be appropriately encouraged, because they are morphologically unremarkable (Spohr 2000, personal communication). The developmentally toxic effect of paternal alcohol exposure observed in some animal experiments and postulated in individual case reports cannot (yet) be proven in humans (Passaro 1998). However, the negative effects on male fertility as a result of alcohol abuse have been proven (see above). It is often difficult to determine the exposure to alcohol in the mother and/or newborn based upon blood alcohol levels, due to the very brief half-life of ethanol. However, recent techniques that measure the ethyl esters of fatty acids in the newborn meconium and hair can provide a history of maternal alcohol exposure (Chan 2003). Primary prevention of developmental and reproductive (fertility) disorders is the main issue. Because alcohol is a proven teratogen, there must be a warning against regular or excessive use. Alcoholism is one of the few situations in which pregnancy interruption may be discussed with the patient. Lying about an alcohol problem during pregnancy has (life-long) consequences for the mother and child. The use of alcohol-containing tonics and medications with an alcohol base cannot be compared with alcohol abuse, but should nevertheless be avoided (see also Chapter 2. This applies to medications with an alcohol base, at least when the concentration exceeds 10%. Caffeine is also an ingredient in many over-thecounter pain and cold medications (see also Chapter 1. These xanthines are well absorbed from the gastrointestinal tract; they cross the placenta, and cause increased fetal activity and a significant increase in its heart frequency. In animal studies, extremely high doses of caffeine (200 mg/kg per day) caused minor development anomalies of the phalanges. Extensive epidemiological studies in several countries gave no indication for any reproductive toxicity or teratogenicity under these conditions (Browne 2006, Castellanos 2002, Christian 2001). The effect on fertility as a result of regular use of larger quantities of caffeine has also been discussed. If significantly higher amounts have been consumed, this does not require any additional diagnostic procedures. Nicotine is absorbed through the mucosa in the mouth cavity, the respiratory system, and the gastrointestinal tract. Nicotine has a half-life of 2 hours; 90% of the nicotine absorbed is metabolized in the liver to hydroxynicotine and cotinine (which has a half-life of 20 hours). Nicotine crosses the placenta unimpeded, and causes the fetal heart frequency to increase. The respective differences in concentrations among children of active and passive smokers, as well as women from non-smoking households, were statistically significant. Smoking is embryo- and fetotoxic, but apparently does not represent a significant risk of birth defects. However, associations between smoking during the first trimester and risks of non-syndromal orofacial clefts (Deacon 2005, Little 2004A, 2004B, Zeiger 2004, Chung 2000) are still under debate. These studies indicate that the risk for genetically predisposed fetuses to develop clefts is increased from 1 in 500 (the general population prevalence) to about 1 in 183. The following effects of smoking during pregnancy have been discussed (see also Werler 1997): Smoking only marginally increases the risk for spontaneous abortion when other risk factors such as alcohol consumption, pregnancy history, social status, and karyotype are considered and decrease uterine receptivity (Soares 2006). Perinatal mortality as a result of abruptio is two to three times higher among the children of smokers than among those of non-smokers. The rate of low birth weight (2500 g) children among smokers is double that among non-smokers.

Radiationinduced ulcers persist throughout the course of therapy and for several weeks afterward pain swallowing treatment buy 600 mg ibuprofen mastercard. Oral mucositis occurs in several phases: (1) an initial phase primarily involving the submucosa and vasculature (2) an epithelial phase treatment for pain associated with shingles purchase ibuprofen 400mg visa, (3) an ulcerative phase pain treatment lupus order ibuprofen online pills, and (4) a healing phase pain treatment center somerset ky discount 600mg ibuprofen free shipping. Risk factors for mucositis have not been well established neck pain treatment youtube buy ibuprofen 400mg with amex, but clearly specific cancer treatment protocols and different chemotherapies produce more mucositis than others back pain treatment natural buy ibuprofen 400mg on-line. Particularly damaging to oral mucosa are antifolate medication such as methotrexate, which produce their anticancer effects through interference with nucleotide synthesis. This chronochemotherapeutic approach has been established for several other anticancer drugs including oxaliplatin, cyclophosphamide, and leucovorin (folinic acid) that are used with methotrexate. Induration, often associated with these lesions, is due to scar formation and chronic inflammatory cell infiltration. Mucosal ulceration related to cancer management starts approximately 10 days following initiation of radiation (at 20 to 30 Gy) and/or chemotherapy. Chronic ulcers have a granulation tissue base, with scar found deeper in the tissue. It has been speculated that these factors are related to inappropriate adhesion molecule expression (integrins) and/or inadequate extracellular matrix receptors for the keratinocyte integrins. In traumatic granulomas, tissue injury and inflammation extend into subjacent skeletal muscle. Here a characteristic dense macrophage infiltrate with eosinophils may dominate the histologic picture. Treatment constitutional symptoms, necrotic cutaneous ulcerations, organ and ocular involvement, and a greater tendency to develop neurosyphilis. Healing of traumatic granuloma is spontaneous, but topical and intralesional steroids can accelerate healing and reduce symptoms. Paul Ehrlich developed his "magic bullet," arsphenamine, around the turn of the twentieth century. When the disease is spread through direct contact, a hard ulcer, or chancre, forms at the site of spirochete entry (Box 2-2). The spirochetemia that develops in the fetus may cause numerous inflammatory and destructive lesions in various fetal organs, or it may cause abortion. Clinical Features Early Late as a result of hematogenous spread of the spirochete. At the labial commissures, split papules may form, while lateral tongue lesions may manifest as deep fissures. The spirochetes are now disseminated widely and are the cause of a reddish brown maculopapular cutaneous rash and mucosal ulcers covered by a mucoid exudate (mucous patches). Fortunately, this stage of syphilis has become a rarity because of effective antibiotic treatment. Inflammatory involvement of the cardiovascular system, especially the aorta, may result in aneurysms. Development of generalized glossitis with mucosal atrophy has been well documented in the tertiary stage of this disease. Although patients with so-called syphilitic or luetic glossitis are thought to have an approximately fourfold increased risk of oral squamous cell carcinoma, it is unclear whether this is a result of the disease, or whether it is due to the carcinogenic agents that were formerly used to treat the condition, such as arsenicals and heavy metals. When the infectious process involves the vomer, a nasal deformity known as saddle nose develops; when periostitis of the tibia occurs, excessive anterior bone growth results in a deformity known as saber shin. Clinically, as well as microscopically, syphilis is said to be the great imitator or mimicker because of its resemblance to many other unrelated conditions. Definitive diagnosis of syphilis is based on laboratory test confirmation of the clinical impression. Among several tests available are (1) darkfield examination of scrapings or exudate from active lesions; (2) special silver stain or immunologic preparation of biopsy tissue; (3) serologic tests for antibodies to T. It is caused by the gram-negative diplococcus Neisseria gonorrhoeae, which infects columnar epithelium of the lower genital tract, rectum, pharynx, and eyes. Genital infections may be transmitted to the oral or pharyngeal mucous membranes through orogenital contact. Pharyngeal mucosa is more likely to be infected than oral mucosa because of the type of epithelium and its reduced resistance to trauma, with pharyngitis as the chief complaint. Developing this form of disease is apparently much more likely with fellatio than with cunnilingus. Individuals may have concomitant genital and oral or pharyngeal infections that result from direct orogenital exposure to these areas rather than from being spread through blood or lymphatics. Transmission of gonorrhea from an infected patient to dental personnel is regarded as highly unlikely because the organism is very sensitive to drying and requires a break in the skin or mucosa to establish an infection. Because of the lack of consistent and distinctive oral lesions, other conditions that cause multiple ulcers or generalized Clinical Features Differential Diagnosis Aphthous ulcers, herpetic ulcers, erythema multiforme, pemphigus, pemphigoid, drug eruptions, and streptococcal infection should be considered. Diagnosis of gonorrhea is traditionally based on demonstration of the organism with Gram stain or culture on Thayer-Martin medium. Treatment Uncomplicated gonorrhea responds to a single dose of appropriately selected antibiotic. In the West, infections are susceptible to penicillins and treatment is effective with a single parenteral dose of 2. This regimen is also appropriate for pharyngeal gonorrhea, for which ampicillin is generally ineffective. In addition, the issue of multidrug resistance has proved to be a growing problem in management of the disease. Phagocytosis by alveolar macrophages follows, and the battle between bacterial virulence and host resistance begins. As the immune system is sensitized by mycobacterial antigens, positive tuberculin reactivity develops. In a small number of cases, the disease may progress through airborne, hematogenous, or lymphatic spread, so-called miliary spread. Oral mucous membranes may become infected through implantation of organisms found in sputum or, less commonly, through hematogenous deposition. The typical lesion is an indurated, chronic, nonhealing ulcer that is usually painful. Bony involvement of the maxilla and mandible may produce tuberculous osteomyelitis. Pharyngeal involvement results in painful ulcers, which may cause dysphagia, odynophagia, and voice changes. The macrophages develop an abundant eosinophilic cytoplasm, giving them a superficial resemblance to epithelial cells; for this reason, they are frequently called epithelioid cells. Fusion of macrophages results in the appearance of Langerhans giant cells, in which nuclei are distributed around the periphery of the cytoplasm. As the granulomas age, central necrosis occurs; this is usually referred to as caseous necrosis because of the gross cheesy texture of these zones. In the absence of acid-fast bacilli, other microscopic considerations would include syphilis, cat-scratch disease, tularemia, histoplasmosis, blastomycosis, coccidioidomycosis, orofacial granulomatosis, sarcoidosis, and some foreign body reactions, such as those induced by beryllium. Inoculation through the respiratory tract is believed to be a potential mode of transmission. Oral lesions appear in the lepromatous form of the disease in 20% to 60% of cases, as multiple nodules (necrotic and ulcerated), with associated slow healing and atrophic scarring. Generally, skin and peripheral nerves are affected because the organism grows best in temperatures less than the core body temperature of 37 degrees C. Cutaneous lesions appear as erythematous plaques or nodules, representing a granulomatous response to the organism. In time, severe maxillofacial deformities may appear, producing the classic destruction of the anterior nasal spine and anterior maxillary alveolus, as well as intranasal inflammation and tissue destruction called facies leprosa. Damage to peripheral nerves results in anesthesia, leading to trauma to the extremities and consequent ulceration, as well as bone resorption. Microscopically, a granulomatous inflammatory response, in which macrophages/epithelioid histiocytes and multinucleated giant cells predominate, is usually seen. Acid-fast bacilli can be found within macrophages and are best demonstrated with the Fite stain. A chronic indurated ulcer should prompt the clinician to consider primary syphilis and oral manifestations of deep fungal diseases. Drug combinations are often used in 6-, 9-, or 12-month treatment regimens, which may be continued for as long as 2 years. Development and testing of new classes of drugs are necessary to meet the challenge of resistant organisms. Patients who convert from a negative to a positive skin test response may benefit from prophylactic chemotherapy, typically using isoniazid for 1 year. The differential diagnosis includes late-stage syphilis, sarcoidosis, cutaneous leishmaniasis, lupus erythematosus, lymphoma, and neoplastic disease. Treatment Current treatment centers on a chemotherapeutic approach in which several drugs are used over a protracted period, typically years. The known teratogen thalidomide is useful for managing the complications of leprosy therapy, as are thalidomide analogs. It is most commonly caused by Actinomyces israelii, an anaerobic or microaerophilic, gram-positive bacterium. On rare occasions, other Actinomyces species may be involved, or the gram-positive anaerobic bacillus propionibacterium propionicus will result in a similar clinical diagnosis. Evidence of other important predisposing factors has been slight, although actinomycotic infections have been recorded in osteoradionecrosis and bisphosphonaterelated osteonecrosis of the jaw, and in patients with serious systemic illness. The lesion may become indurated and eventually may form one or more draining sinuses, leading from the medullary spaces of the mandible to the skin of the neck. Less commonly, the maxilla may be involved, resulting in an osteomyelitis that may drain through the gingiva via a sinus tract. At the center of the abscesses, distinctive colonies of grampositive organisms may be seen. Radiating from the center of the colonies are numerous filaments with clubbed ends. Clinically, actinomycosis may have to be differentiated from osteomyelitis caused by other bacterial or fungal organisms. Infection of the soft tissue of the neck, such as scrofula, and staphylococcal infection, such as botryomycosis, may also be considered. Therapy involves treating the underlying predisposing condition, as well as the infection itself. Antibiotics of choice include clindamycin, piperacillin, and the aminoglycoside gentamicin. Debridement of necrotic tissue may be beneficial if destruction is extensive, with reconstructive surgery a late option following acute management and healing. Fungal Infections Deep Fungal Infections Etiology and Pathogenesis Treatment Long-term, high-dose penicillin, or penicillin analogs is the required antibiotic regimen for actinomycosis. In severe cases, intravenous penicillin followed by prolonged oral penicillin administration from several months to up to a year in deep, chronic disease is a standard regimen. Noma, also known as cancrum oris and gangrenous stomatitis, is a devastating disease of malnourished children that is characterized by a destructive process of the orofacial tissues. The condition is rare in developed countries but is a relatively common cause of childhood mortality and morbidity in parts of Africa, South America, and Asia. Noma Etiology and Pathogenesis Deep fungal infections are characterized by primary involvement of the lungs. Histoplasmosis, a dimorphic saprophytic fungus found in the soil contaminated with bird or bat feces, has a worldwide distribution, although it is endemic in the midwestern United States. It has been proposed that noma results from oral contamination by a heavy infestation of Fusobacterium necrophorum, and a consortium of other microorganisms, including Prevotella intermedia, Borrelia vincentii, Treponema denticola, Porphyromonas gingivalis, and Staphylococcus aureus. A related disorder, noma neonatorum, occurs in low-birth-weight infants who suffer from other debilitating diseases. The initial lesion of noma is a painful ulceration, usually of the gingiva or buccal mucosa, which spreads rapidly and eventually becomes necrotic. Denudation Deep Fungal Infections Pathogenesis Inhalation of spores Symptoms Cough, fever, weight loss, other Primary Site Lung; may be asymptomatic Oral Lesions Chronic, nonhealing ulcers resulting from lung disease Clinical Features Microscopy Granulomatous inflammation with organisms Treatment Ketoconazole, fluconazole, itraconazole, amphotericin B Blastomycosis is usually encountered in North America, especially in the Ohio-Mississippi River basin area. Cryptococcus infection may be transmitted through inhalation of avian excrement, but it also may occur in immunocompromised patients. Whether single or multiple, lesions are nonhealing, indurated, and frequently painful. Histopathology Diagnosis Biopsy necessary Culture may be required Treatment Appropriate antimicrobial agent the basic inflammatory response in a deep fungal infection is granulomatous. After an incubation period of several weeks, subcutaneous nodules, which frequently become ulcerated, develop. Central abscesses may be found in some of the granulomas, and overlying epithelium may exhibit pseudoepitheliomatous hyperplasia. Treatment of deep mycotic infection generally consists of antimicrobials such as ketoconazole, fluconazole, and amphotericin B. In immunocompromised transplant recipients or in debilitated patients, more aggressive medical management with newer agents such as echinocandins, posaconazole, and voriconazole may be necessary. Sporotrichosis is difficult to diagnose since it resembles several other diseases and serological testing for antibodies to S. Sporotrichosis usually is treated with a solution of saturated potassium iodide and, less commonly, with systemic antifungal agents. Treatment Treatment Opportunistic Fungal Infections: Mucormycosis (Phycomycosis) and Aspergillosis Etiology and Pathogenesis Zygomycosis is a broad term that refers to infections caused by several bread mold fungi of the zygomycota group. Treatment In the head and neck, lesions are most likely to occur in the nasal cavity, paranasal sinuses, and possibly the oropharynx. Rarely, a periodontal presentation may be noted, usually associated with a preexisting medical condition, in particular those conditions where immunosuppression is present. The organism is usually and readily identified in hematoxylin and eosin (H&E)-stained sections in areas of tissue necrosis. Microscopically, the fungus consists of large, pale-staining, nonseptate hyphae that tend to branch at right angles. It is important for clinicians to recognize that several opportunistic fungal infections can arise in the nasal and paranasal sinuses of an immunocompromised host.
