Interdigital Pilonidal Sinus

In the web space of his left hand, a 50-year-old barber had a painful cystlike lesion. The lesion had recurred intermittently, despite oral antibiotic treatment and warm compresses. The patient's father, also a barber, had a similar, more severe condition, which eventually required surgical intervention.

Asthma:

ABSTRACT: Education can help improve compliance with inhaled corticosteroid therapy or correct faulty metered-dose inhaler (MDI) technique. Options for patients with poor MDI technique include use of a spacer or an alternative device, such as a nebulizer or a dry powder inhaler. If therapy is ineffective, consider alternative conditions that mimic asthma, especially vocal cord dysfunction and upper airway obstruction. Treatment of comorbid conditions, such as gastroesophageal reflux disease or rhinosinusitis, may improve control. In refractory asthma, it is crucial to identify allergic triggers and reduce exposure to allergens. If another medication needs to be added to the inhaled corticosteroid, consider a long- acting b-agonist, leukotriene modifier, or the recombinant monoclonal anti-IgE antibody omalizumab.

Kaposi's Sarcoma in the Sigmoid Colon

A 2-week history of diarrhea mixed with bright red blood was the presenting complaint of a 40-year-old man who was seropositive for HIV. Stool studies and culture results were negative for microorganisms. Colonoscopy demonstrated only the raised vascular lesion seen here in the sigmoid colon, which may have been responsible for the bleeding.

New Advances in Antiretroviral Therapy

It is estimated that approximately 33.2 million persons worldwide were living with HIV infection in 2007.1 With the development of effective antiretroviral treatment strategies, HIV infection has now become a manageable chronic disease.2 Despite advances in treatment, drug resistance, long-term adverse effects, and high adherence requirements represent ongoing challenges to durable viral suppression.

Unexplained Chest Pain:

ABSTRACT: Once you have excluded a cardiac origin of chest pain, focus the evaluation on esophageal, psychiatric, musculoskeletal, and pulmonary causes. Gastroesophageal reflux disease (GERD) and esophageal motility disorders are the most common causes of unexplained chest pain (UCP). If you suspect an esophageal disorder, empiric antisecretory therapy is the most cost-effective initial approach. If the patient remains symptomatic, order a 24-hour esophageal pH study with symptom analysis while the patient receives maximal acid suppression. Once GERD is excluded, the patient may be treated for visceral hyperalgesia with low-dose tricyclic antidepressants or standard doses of selective serotonin reuptake inhibitors. Panic disorder-the most common psychiatric disorder in patients with UCP-is often associated with atypical symptoms, such as palpitations and paresthesias, and other psychiatric disorders. If you suspect panic disorder, one approach is to give the patient a short-term, nonrefillable prescription for a benzodiazepine and refer him or her for psychiatric evaluation.

A soft systolic murmur was heard over the left precordium; the lungs were clear. A posteroanterior chest film showed no rib fracture but it did show an enlarged heart and a large, calcified ventricular aneurysm.

Congestive Heart Failure Therapy:

ABSTRACT: Recent studies, although suggestive, do not yet support the routine use of angiotensin II receptor blockers in combination with angiotensin-converting enzyme (ACE) inhibitors in patients with congestive heart failure (CHF). For CHF patients in normal sinus rhythm, consider digoxin when a regimen of diuretics, ACE inhibitors, and β-blockers at optimal dosages does not relieve symptoms completely. Anticoagulation may be warranted in CHF patients with atrial fibrillation, previous embolic events, severely reduced systolic performance, or potential chamber clots. β-Blockers are indicated for patients with mild to severe CHF, unless there is a specific contraindication, and therapy should be initiated once euvolemia has been achieved. Avoid NSAIDs and cyclooxygenase-2 inhibitors in patients with CHF because the prostaglandin-blocking properties of these agents may promote fluid retention.

The keys to quickly identifying anaphylaxis

Abstract: The classic presentation of anaphylaxis includes urticaria, angioedema, dyspnea, and systemic hypoperfusion. However, anaphylaxis may be more difficult to recognize if syncope, bronchospasm, or cardiovascular collapse is the predominant feature. Essential components of the history include previous allergic reactions, medication use, recently ingested foods, and exposure to latex. Although angioedema is often obvious, it also can be subtle and may require asking patients about changes they have observed. Other findings include tachypnea; wheezing; inspiratory stridor; conjunctival injection; rhinorrhea; and hoarseness, which may suggest laryngeal edema. Oxygen with ventilatory support, epinephrine, and crystalloid volume resuscitation are the mainstays of therapy for anaphylactic shock. Additional therapy often includes H1 antagonists, H2 antagonists, and corticosteroids. (J Respir Dis. 2005;26(7):308-316)

Tinea Corporis: An Overview

Dermatophyte infections have a predilection for certain anatomic sites, such as the feet, groin, and scalp. Tinea corporis refers to involvement of the trunk and extremities. The condition arises either from direct exposure to an infected source or by extension from an adjacent affected site. Itch is a common symptom, but the intensity of the pruritus can vary from patient to patient.

PSA Recurrence of Prostate Cancer:

ABSTRACT: Prostate-specific antigen (PSA) recurrence is the most common form of advanced prostate cancer. Salvage therapies may be effective even among some high-risk men, although long-term cancer control data are limited. The natural history of PSA recurrence is long but variable. The postrecurrence PSA doubling time can identify men at high risk for progression and death. Early hormonal therapy, possibly via combined androgen blockade, may reduce the risk of progression and improve cancer-specific survival among men with high-risk recurrence. Men with low-risk recurrences likely receive minimal benefit from aggressive early hormonal therapy and may actually be harmed.
