A patient with AIDS and an abnormal chest x-ray

Article Abstract:

X-rays and sputum studies were used to diagnose a 34-year-old HIV-positive homosexual white man with M avium complex (MAC) infection. At first diagnosed with Mycobacterium tuberculosis and treated with isoniazid, rifampin, ethambutol, and pyrazinamide, later sputum specimens confirmed his MAC infection and his treatment was changed to rifabutin. Because of the possibility of drug resistance developing when patients stop using tuberculosis drugs, drug therapy for MAC infection should be discontinued only when a patient dies.

Cavitary lung lesions in an AIDS patient

Article Abstract:

A 38-year-old homosexual man from Central America dying of AIDS developed several cavitary lung lesions five weeks before he died. He had already been diagnosed with mycobacterium avium complex when he developed a cough, then with Pseudomonas aeruginosa and was being treated for them. Tuberculosis rarely causes cavity formation in AIDS patients, so it was thought to be an unlikely diagnosis, but Staphylococcus aureus embolization was thought to be likely.

Urinary tract infections in otherwise healthy nonpregnant adult women: a clinical approach to diagnosis and management

Article Abstract:

Urinary tract infection can affect many otherwise healthy women and can be diagnosed through medical history or dipstick urinalysis. Treatment usually involves a short course of antibiotics, but a more serious condition may require a longer course or an alternative strategy. Urine cultures are not necessary for most diagnoses.
