HAND-FOOT-AND-MOUTH DISEASE Hand-foot-and-mouth disease is caused by a coxsackievirus generic omnicef 300mg online. Outbreaks are most com- mon in the summer and fall months. On occasion, the condition is associated with menin- gitis. Skin and oral lesions are often preceded by a period of malaise and fever. The patient often presents once the oral lesions appear on the lips and/or oral mucosa. The lesions erupt as vesicles, which later ulcerate. Multiple lesions are located on the lips and oral mucosa. As the condition’s name implies, the lesions often appear on the hands and feet, as well as in the mouth. Lesions may also be evident on the genitalia and buttocks. The patient’s hydration status should be monitored, if the lesions impair ability to take food and/or ﬂuids by mouth. CANDIDIASIS Candidiasis is caused by a species of the fungal genus Candida. Risk factors for candidi- asis include an impaired immune system, antibiotic therapy, malignancy, and recent surgery or trauma. Candidiasis affects a variety of systems and tissues, including the oral mucosa. Candidal infections of the oral mucosa take several forms. Thrush, or pseudomembra- nous candida, results in white patches or plaques overlying a very red base.
Advanced disease is associated with a poor prognosis buy 300 mg omnicef with mastercard. The most serious complications of CTCL are infections: sepsis from ulcer- ated cutaneous tumors is a common cause of death in these patients. A 56-year-old white man presents to your office for evaluation of bumps on his upper back and chest. His wife reports that he has had them for years, but they seem to be increasing in number. Examination reveals several sharply circumscribed papules measuring from 2 mm to 2 cm in diameter on the patient’s upper back and chest. The lesions are light brown and have a stuck-on appearance. Dermatosis papulosa nigra 2 DERMATOLOGY 27 Key Concept/Objective: To be able to recognize seborrheic keratosis and to be familiar with the differential diagnosis of lesions with a similar appearance This patient’s lesions are consistent with seborrheic keratosis (seborrheic wart). Seborrheic keratosis is a very common epithelial tumor that tends to occur on the upper trunks of light-skinned adults. The color can range from dirty yellow to dark brown, and their size varies from 1 mm to several cm. They may be rough or smooth but often have a waxy surface. Dermatosis papulosa nigra is similar to seborrheic keratosis but tends to occur in dark-skinned individuals (this patient is white) and is usually localized on the face. In addition, dermatosis papulosa nigra tends to pres- ent at an earlier age than does seborrheic keratosis. The differential diagnosis of seborrhe- ic keratosis also includes lentigo, warts, nevus cell nevus, and pigmented basal cell carci- noma. Inflamed seborrheic keratosis can be difficult to distinguish from malignant melanoma and squamous cell carcinoma. Transient development of seborrheic keratosis has been associated with inflammatory skin conditions such as drug-related erythroderma and psoriasis.
You suspect that she was bitten by a brown recluse spider buy 300 mg omnicef visa. Which of the following therapies is LEAST likely to benefit the victim of a brown recluse spider bite? Administraton of steroids within 24 hours of the bite B. Administration of dapsone in patients who do not have glucose-6- phosphate dehydrogenase deficiency C. Use of antibiotics if there are signs of infection at the bite site D. These spiders are found under rocks and woodpiles in the south central United States. Their bite can cause pain within the first few hours of envenomation. Physical findings are a ring of pallor surrounded by ery- thema. These may eventually evolve to form a bleb, which can become necrotic. The necrosis can spread and may eventually form an eschar. There is some evidence of ben- efit from treatment with systemic steroids within 24 hours of envenomation. Dapsone has been shown to be helpful in treating the local damage caused by the venom. However, dapsone can cause a serious hemolytic reaction in those with glucose-6-phos- phate dehydrogenase deficiency.
