Cefpodoxime-proxetil versus trimethoprim-sulfamethoxazole for short-term therapy of uncomplicated acute cystitis in women.

One hundred sixty-three women with uncomplicated acute lower urinary tract infections were included in a multicenter randomized study comparing cefpodoxime-proxetil (one 100-mg tablet twice daily) with trimethoprim-sulfamethoxazole (one double-strength tablet [160/800 mg] twice daily) for 3 days. A total of 30 women in both arms were excluded from the study for various reasons. At 4 to 7 days after the discontinuation of therapy, 62 of 63 (98.

Abdominal retained surgical sponges: CT appearance.

Retention of surgical sponges is rare. They cause either an aseptic reaction without significant symptoms or an exudative reaction which results in early but nonspecific symptoms. Computed tomography is very useful for recognition of retained sponges.

MRI of abdominal hydatid disease.

Seventy hydatid cysts in 30 patients were studied with magnetic resonance imaging (MRI) and computed tomography (CT); all cases were confirmed surgically. MRI detected all cysts when confined to solid organs, whereas small-sized cysts (< or = 2 cm) may be missed when located in the peritoneal cavity. Hydatid cysts of less than 3 cm (noncomplicated) present no specific findings of hydatid disease.

Combination chemotherapy with cyclophosphamide, adriamycin, and vincristine in malignant thymoma and myasthenia gravis.

Malignant thymoma (MT) is a rare tumor that is often associated with myasthenia gravis (MG). This tumor is considered resistant to chemotherapy. We had the opportunity to treat five patients with MT with cyclophosphamide 800 mg/m2, Adriamycin 50 mg/m2, and vincristine 1.

CT characterization of multivesicular hydatid cysts.

One hundred seventy-eight abdominal multivesicular hydatid cysts were classified into three types (A, B, C) based on CT densities and morphology of cysts. The CT density of viable daughter cysts was always appreciably lower than those of mother hydatid cysts. This density differential between mother and daughter hydatid cyst fluid is a useful diagnostic sign.
