Superficial adenopathy is the most common symptom ofcatscratch disease (CSD) attributed to Bartonella henselaeinfection. More complicated adenopathy with pulmonaryinvolvement can occur. We report a case of a 15-year-oldboy with pleural symptoms related to B henselae–associatedCSD. [Infect Med. 2008;25:248-250]

For 3 months, a 63-year-old man had experienced progressively worsening dyspnea. He denied fever, weight loss, and hemoptysis. Eight months earlier, he had had a right thoracotomy to drain a right empyema. Comorbidities included morbid obesity, type 2 diabetes mellitus, hypertension, and obstructive sleep apnea. However, he did not have any intrinsic lung disease.

Bronchopulmonary sequestrationis a rare congenitallung malformation characterizedby an abnormal segmentof bronchopulmonary tissuesupplied by an anomaloussystemic artery. The diagnosismay be easily missed in adults,since many are asymptomatic;moreover, symptoms, whenpresent, often overlap withthose of other pulmonaryprocesses. Surgical resectionprovides definitive managementand is usually reservedfor patients with symptoms.We present a case of intralobarbronchopulmonary sequestrationthat presented duringadulthood.

A 62-year-old man was admitted to the hospital with iron deficiency anemia, as demonstrated by low serum iron and ferritin levels and high total iron–binding capacity. He had had this condition for at least the last 5 years and had been treated with ferrous sulfate sporadically. The history coupled with the laboratory findings and the telangiectatic lesions on his lower lip led to a diagnosis of hereditary hemorrhagic telangiectasia, or Rendu-Osler-Weber disease.

Four days after having been given cefuroxime for sinusitis, a 49-year-old woman experienced abdominal cramping, diarrhea, fever (temperature of 39.4°C [103°F]), and nausea. These problems persisted for 1 week, at which time the patient arrived at the emergency department. She had no recent history of travel, ingestion of undercooked food, or exposure to anyone with similar digestive problems.

Abstract: Shortness of breath is a common complaint associated with a number of conditions. Although the results of the history and physical examination, chest radiography, and spirometry frequently identify the diagnosis, dyspnea that remains unexplained after the initial evaluation can be problematic. A stepwise approach that focuses further testing on the most likely diagnoses is most effective in younger patients. Early bronchoprovocation challenge testing is warranted in younger patients because of the high prevalence of asthma in this population. Older patients require more complete evaluation because of their increased risk of multiple cardiopulmonary abnormalities. For patients who have multiple contributing factors or no clear diagnosis, cardiopulmonary exercise testing can help prioritize treatment and focus further evaluation.

ABSTRACT: Indications for pulmonary function tests (PFTs) have widened substantially, ranging from screening smokers for early lung disease to determining the diagnosis and prognosis of pulmonary conditions. Current indications also include screening for drug-induced lung toxicity and preoperative screening for lung resection surgery. In the workup of respiratory symptoms, such as dyspnea, cough, and wheezing, PFTs can identify obstructive or restrictive patterns that may suggest a diagnosis such as asthma or interstitial lung disease. The ratio of FEV1 to forced vital capacity is very sensitive to the presence of airflow limitation, although bronchoprovocation testing may be needed to diagnose asthma, especially in patients with mild intermittent disease. Measurements of lung volumes and carbon monoxide-diffusing capacity (DLCO) provide crucial information in selected patients. For example, a reduced DLCO may be a sign of more advanced disease, such as emphysema or pulmonary hypertension.Since the first description of the spirometer by John Hutchinson in the late 1800s, pulmonary function tests (PFTs) have expanded to include spirometry; lung volumes; carbon monoxide-diffusing capacity (DLCO) (transfer factor); respiratory muscle performance; and exercise and functional testing, such as the 6-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET).

Traveler's diarrhea (TD) occurs in persons traveling fromindustrialized countries to less developed regions of the world.Because of the growing ease of travel and an increasinglyglobalized economy, TD is becoming more common. Increasingantibiotic resistance among causative bacterial organisms andalso emergence of new pathogens are additional challenges inthe management of TD. Enterotoxigenic and enteroaggregativepathotypes of Escherichia coli are the principal causes of TD.This review discusses the epidemiology of these pathogens, aswell as elements of prevention, diagnosis, and management.[Infect Med. 2008;25:264-276]

Combination therapy with pegylated interferon alfa-2a or alfa-2b and ribavirin (RBV) results in a greater rate of sustained virologic response (SVR) than that seen with standard interferon alone. Patients infected with hepatitis C virus genotype 1 require higher doses of RBV and a longer duration of therapy than do patients infected with genotype 2 or 3. Closely monitor patients for neuropsychiatric effects, especially depression, and hematologic and other toxicities. Because of the teratogenicity of RBV, strict birth control must be used throughout the course of treatment and for 6 months afterwards. Patients who have not demonstrated a 100-fold reduction in viral load after 12 weeks of therapy are unlikely to achieve SVR; discontinuation of therapy may be considered.

To distinguish between hypertensive emergencies and urgencies and nonurgent acute blood pressure elevation, evaluate the patient for evidence of target organ damage. Perform a neurologic examination that includes an assessment of mental status; any changes suggest hypertensive encephalopathy. Funduscopy can detect papilledema, hemorrhages, and exudates; an ECG can reveal evidence of cardiac ischemia. Order urinalysis and measure serum creatinine level to evaluate for kidney disease. The possible causes of a hypertensive emergency include essential hypertension; renal parenchymal or renovascular disease; use of various illegal, prescription, or OTC drugs; CNS disorders; preeclampsia or eclampsia; and endocrine disorders. A hypertensive emergency requires immediate blood pressure reduction (although not necessarily to the reference range) with parenteral antibiotics. An urgency is treated with combination oral antihypertensive therapy.

The CDC estimates that more than 850,000 people are living with HIV/AIDS in the United States today,1 with African Americans and Latinos being disproportionately affected.2 Over the past decade, the Latino population in the United States has been growing. In fact, in 2002 for the first time, Latinos surpassed African Americans as the largest US minority group. However, the term "Latino" is applied to a very heterogeneous group from different countries and different cultures.3 In addition, a large proportion of Latinos is undocumented in the United States and thus marginalized from the health care system.

abstract: Pulmonary arterial hypertension (PAH) is 1 of 5 types of pulmonary hypertension (PH). Symptoms may include dyspnea on exertion, fatigue, near-syncope, and palpitations. Physical findings include lower extremity edema, jugular venous distention, and a loud P2. Findings on chest radiography, transthoracic echocardiography, and electrocardiography can suggest the presence of PAH; however, right heart catheterization is the gold standard for confirming the diagnosis and for differentiating PAH from other forms of PH. It is essential to exclude chronic thromboembolic PH, since this can be surgically corrected. The treatment of PAH depends on the severity. In addition to the standard treatments, such as diuretics and anticoagulation, more advanced treatment options include prostaglandin therapy (epoprostenol, treprostinil, and iloprost), endothelin receptor antagonists (bosentan), and phosphodiesterase inhibitors (sildenafil).
