Survival in a case of diffuse alveolar hemorrhage due to Strongyloides stercoralis hyperinfection.

Strongyloides stercoralis is an intestinal nematode endemic to tropical and sub-tropical regions. Although infection is typically asymptomatic or self-limited, immunocompromised individuals can develop a severe form of disease marked by hyperinfection. Pulmonary involvement accompanies hyperinfection in a majority of cases, though manifestations range from asymptomatic infiltrates to diffuse alveolar hemorrhage (DAH) and respiratory failure.

Peripheral blood CD4 + T-lymphocyte counts during Pneumocystis carinii pneumonia in immunocompromised patients without HIV infection.

Study Objectives: To assess the potential use of peripheral blood CD4 + T-lymphocyte counts (CD4 + counts) as a clinically useful biological marker to identify specific immunocompromised patients (without HIV infection) at high risk for Pneumocystis carinii pneumonia (PCP).

Design: Prospective observational study.

Setting: Three hundred seventy-five-bed tertiary-care urban referral teaching hospital, and 250-bed community-based referral hospital.

Pneumocystis carinii pneumonia prophylaxis in patients with rheumatic diseases undergoing immunosuppressive therapy: prealence and associated features.

Pneumocystis carini (PCP) has been recognized as a cause of pneumonia in immuocompromised patients, most notably in AIDS patients, but also in those receiving immunosuppressive therapy for a variety of other conditions, including malignancy, having an organ transplant, connective tissue diseases, and vasculitic syndromes. In non-HIV PCP patients, presentations may be more dramatic than in HIV-related PCP and the mortality may be higher, thus emphasizing the need to identify and provide prophylaxis for those at highest risk for PCP. The incidence of PCP varies in different rheumatic disorders, with the highest rated noted in Wegener's granulomatosis and the lowest noted in rheumatoid arthritis.

Recent Dieulafoy's lesion bleeding and massive pulmonary emboli. Successful use of thrombolytic therapy.

A massive GI bleed secondary to a Dieulafoy's lesion developed in a 77-year-old woman. Fifteen days later, massive pulmonary emboli developed. We describe successful thrombolytic treatment of her pulmonary emboli without complicating GI hemorrhage.
