For more than 20 years, a 55-year-old man had a faintly erythematous, papulosquamousrash with arciform borders on his groin and waistline. The rashhad been treated with a variety of medications. Topical and oral antifungalsand antibiotics and topical corticosteroids had been used but to no avail. Nolaboratory tests had been performed.
For 1 year, a 30-year-old man had an intermittent rash that was confined to thearea of his jockey shorts; no other part of the body was affected. The patientreported that the pruritic eruption arose and disappeared spontaneously andwas more prominent during the heat of summer.
A 50-year-old man had a long-standing rash on both soles. The patient’s toenails were yellow and dystrophic. These physical findings strongly suggested moccasin-variety tinea pedis and onychomycosis.
For years, a 39-year-old man had an eruption on his hand, which seemed to becontrolled with topical corticosteroids. The patient was a rancher.
For 2 months, an asymptomatic rash had been present on the upper arms of a 16-year-old boy of normal weight. The rash, as seen on the patient’s right arm, consisted of abundant fine papules. He had no other lesions.
A 33-year-old active-duty soldier who had been in Iraq for 6 months presented with a depressed lesion on his left lateral elbow of several months’ duration. It was neither healing nor enlarging. (The yellowish tint to the skin in the photograph was from a topical iodine solution.)
The continuous use of a corticosteroid cream briefly relieved the pruritus of anannular, papulosquamous eruption on the left anterior thigh of a 50-year-oldwoman. The lesion was present for 6 months and grew larger with applicationof the topical corticosteroid.
ABSTRACT: The chief causes of ingrown toenails are trauma, incorrect toenail trimming, and tight footwear. Conservative measures, which include decreased activity, warm soaks, antibiotic therapy, elevating the edge of the impinged nail, debridement, or removal of the corner of the toenail containing the spike, may relieve moderate inflammation and infection. For patients who have severe impingement with acute infection, partial or complete nail avulsion is the treatment of choice. If avulsion is followed by recurrent infection, partial or complete ablation of the nail matrix may become necessary after the infectious process has resolved. Teach patients to trim their toenails straight across and not to curve them toward the lateral margins.
ABSTRACT: Urinary incontinence is a widespread disorder that remains underdiagnosed, underreported, and undertreated. Nevertheless, it is highly treatable. Components of the initial office evaluation include a focused history taking, physical examination, a postvoid residual urine volume measurement, and urinalysis. Behavioral interventions are first-line therapy. These include bladder training, pelvic floor muscle training, biofeedback therapy, and caregiver-dependent interventions. The antispasmodics oxybutynin and tolterodine are the most commonly used agents for urge incontinence. Stress incontinence can be treated with pseudoephedrine or topical vaginal estrogen. Imipramine may be helpful in cases of nocturnal or mixed incontinence. Overflow incontinence caused by an anatomic obstruction may be treated with an α-blocker.
ABSTRACT: Consider prophylactic therapy for patients with frequent (5 or more per month), severe migraine attacks; commonly used agents include β-blockers, calcium channel blockers, antidepressants, and antiepileptic agents. Daily or alternate-day use of aspirin or an NSAID may also be helpful, and limited data suggest angiotensin II receptor blockers may provide effective migraine prophylaxis. For treatment of acute migraine attacks, triptans have emerged as the most effective agents. Controlled clinical trials have demonstrated that all the triptans have similar efficacy. The optimal strategy for an acute migraine attack is to initially administer a therapeutic agent at a dose sufficient to relieve symptoms. Intervention during the early, mild stages of an attack is more likely to alleviate pain than intervention after moderate to severe symptoms occur.

ABSTRACT: Signs and symptoms of a full-blown ocular allergic reaction include deep red vessels in the conjunctiva, itching, and swelling of the conjunctiva and eyelids. Ocular allergy can resemble nonallergic conditions, including drug-induced conjunctivitis, blepharitis, and viral or bacterial infection. A history of itching confirms a diagnosis of allergy. To distinguish allergic conjunctivitis from more serious allergic ocular diseases, inspect the lids and cornea for papillae on the upper tarsal surface, which occur in giant papillary conjunctivitis and vernal or atopic keratoconjunctivitis. Local treatment of allergic conjunctivitis consists of over-the-counter and prescription antihistamines, with or without vasoconstrictors or mast cell stabilizers. Combination mast cell stabilizer/ antihistamine topical ophthalmic agents-the newest class of medication-are considered the most effective treatment of allergic conjunctivitis. Oral antihistamines are not indicated unless a patient has an allergic condition, such as rhinitis, dermatitis, or asthma.
ABSTRACT: The presence of blood in the urine is a significant finding that calls for prompt evaluation. Gross hematuria usually indicates a serious problem; its correlation with malignancy-typically a transitional cell carcinoma-is fairly high. Microscopically detectable blood is less likely to signal a major underlying condition; a finding of 0 to 3 red cells per high-power field is probably innocent. The workup for gross and microscopic hematuria focuses on disturbances of urinary tract function and includes a history and physical examination, urinalysis, radiologic imaging, urine cytology, and cystoscopy. The presence of hematuria, proteinuria, and renal insufficiency warrants referral to a nephrologist. A search for the cause of microscopic hematuria is much less likely than a workup for gross hematuria to uncover a life-threatening condition. If the hematuria persists, repeat the urinalysis and cytology every 6 months until the problem resolves or 3 years have passed.
A 40-year-old womanwith HIV infection has had an occasionallypruritic facial rash for severalmonths. The rash is not associatedwith any systemic symptoms.
A 46-year-old man with diabetes presented for evaluation of gradual fingernail deterioration, which had failed to respond to several courses of griseofulvin and a recent 3-month course of daily terbinafine. The patient-who worked as a bartender-was otherwise healthy.
For several weeks, a 78-year-old woman had an intensely pruritic, diffuse, raised, slightly scaly, erythematous rash that persisted despite the use of several over-the-counter topical medications (such as hydrocortisone and clotrimazole cream). Since her last visit about 3 months earlier for a blood pressure reading, she had been well except for 2 episodes of night sweats.
Sorting through the myriad of causes of soft tissue infections can be a daunting diagnostic challenge. While much is written about empiric treatment of skin and soft tissue infections, it is important to make a correct diagnosis, since clinical findings in common versus exotic and mild versus life-threatening infections have significant overlap. Historical information, such as the temporal progression of signs and symptoms, travel history, animal exposure, age, occupation, bite history, underlying diseases, and lifestyle, is important in focusing the differential diagnosis toward specific causes. Still, clinical assessment is frequently not sufficient and laboratory tests, radiographic imaging, and surgical intervention may be necessary to establish a specific diagnosis and to provide the rationale for definitive management.
A 52-year-old man complains of nausea, fever, and malaise following a 2-day diarrhealillness that developed at the end of a family vacation in New England.Two family members suffered a similar illness, characterized by watery diarrhea.Symptoms developed in all who were affected within 24 hours of eatinghamburgers at a local restaurant.
A 70-year-old man who had just completeda course of trimethoprim-sulfamethoxazolefor a urinary tract infectionpresented with palpable purpuraand cutaneous erosions of acute onseton his legs (A). He also had massivescrotal edema and purpura (B).
ABSTRACT: Because physical findings are an unreliable indicator of deep venous thrombosis (DVT), the diagnosis is based on the presence of clinical risk factors and the results of noninvasive tests, such as duplex ultrasonography and impedance plethysmography. Contrast venography is considered the gold standard for the diagnosis of DVT. Uncomplicated DVT is managed with low molecular weight heparin followed by warfarin. When DVT is complicated (eg, by pregnancy or by evidence of pulmonary embolism), the patient is treated with intravenous heparin; the dosage is adjusted to achieve an activated partial thromboplastin time 3 times control. Chronic venous insufficiency is the most common cause of leg ulcers. Treatment goals include reduction of edema, relief of pain, ulcer healing, and prevention of recurrence. Leg elevation and multilayer elastic compression dressings are the mainstays of therapy. Compression dressings are continued until ulcers heal; graded compression stockings are worn to prevent recurrence. Pentoxifylline, 400 mg 3 times a day, is an effective adjunct to compression bandaging. Large or slow-healing ulcers may require skin grafts.
During the past week, a rash on theright thumb and forefinger of a 4-yearoldboy has progressed to involve theentire arm.
A palpable papulosquamous, arciform chronic eruptionhad been present in a 70-year-old man for many years.The asymptomatic rash was in a “mantle” distribution-across the upper shoulders, neck, and back.
Large, reddish tan, asymptomatic patches recently developedon the trunk of a 36-year-old man. Five years earlier,a similar outbreak had resolved after a 10-day course oforal ketoconazole; this episode was the first recurrence.
For several months, a 19-year-old manhad asymptomatic hyperpigmentedand hypopigmented macules on theright volar forearm. Recent applicationsof topical corticosteroids madethe lesions more noticeable.
