Extrapulmonary tuberculosis in pregnancy masquerading as a degenerating leiomyoma.

Background: Tuberculosis (TB) is an increasingly common infectious complication of pregnancy. The diagnosis of extrapulmonary TB in pregnancy is hampered by many factors and thus often delayed, and that has the potential of increasing morbidity and mortality.

Case: This case involves a gravida with extrapulmonary TB, which was originally diagnosed as a degenerating leiomyoma.

Core cancer length in ultrasound-guided systematic sextant biopsies: a preoperative evaluation of prostate cancer volume.

Objectives: Evidence has been presented that biologic aggressiveness of prostate carcinoma increases with volume and that cancers less than 0.5 cc may be regarded as clinically insignificant for immediate treatment. We have analyzed the ability of core cancer length on needle biopsy to predict cancer volumes near the 0.

Spermatic cord metastasis from transitional cell carcinoma of the bladder.

A case of transitional cell carcinoma of the bladder metastasizing to the spermatic cord is reported. This represents the only clinically recognized site of tumor recurrence in a man treated with radical cystoprostatectomy followed by four cycles of adjuvant cis-platinum/methotrexate/vinblastine (CMV) chemotherapy for Stage D1 disease (local pelvic lymph node involvement). The existing literature concerning metastatic tumors of the spermatic cord is reviewed.

Large, organ confined, impalpable transition zone prostate cancer: association with metastatic levels of prostate specific antigen.

We present 3 of 25 patients with massive, occult transition zone cancers 7 to 86 cc in volume. Despite serum prostate specific antigen (PSA) levels of 150 to 456 ng./ml.

Inflammatory pseudotumor of the bladder.

Inflammatory pseudotumor of the bladder is an unusual benign lesion arising from the bladder submucosa. We present 2 cases and describe the clinical presentation, and radiographic and histological findings. This benign lesion must be differentiated histologically from several malignant lesions of the bladder.

Intravesical migration of intrauterine device.

Intrauterine devices have been plagued by many early and late complications, including uterine perforation and migration into adjacent structures. To our knowledge only 18 cases have been reported in the literature of migration of an intrauterine device into the bladder. We report on a 38-year-old woman in whom an intrauterine device eroded from the uterus 3 years after placement.

Surgical management of renal cell carcinoma with intracaval neoplastic extension above the hepatic veins.

Cardiopulmonary bypass, hypothermia, temporary cardiac arrest and exsanguination represent the next logical step in the evolutionary management of intracaval neoplastic extension with renal cell carcinoma. This method of management provides control of the circulation of the entire body and allows for careful dissection in a bloodless field with less risk of embolization. From 1981 to 1986, 15 patients were treated with intracaval neoplastic extension of renal cell carcinoma above the level of the most inferior hepatic veins.

Molecular epidemiology of transmissible gentamicin resistance among coagulase-negative staphylococci in a cardiac surgery unit.

The prevalence of colonization of patients in a cardiac surgery unit with gentamicin-resistant, coagulase-negative staphylococci increased from 20% to 68% over a period of four years. Gentamicin resistance was found to be plasmid associated and transmissible from wild-type coagulase-negative staphylococcal donors to a Staphylococcus aureus recipient by filter mating (conjugative). These plasmids were present in isolates from 50 (74%) of 69 individuals examined.

Relationship of size and payment mechanism to system performance in 11 medical care systems.

The performance of 11 medical care systems of varying size and payment mechanisms (consisting of six government owned and operated Indian Health Service units, three fee-for-service private practices and two HMOs) was studied. Performance was defined as the percentage of consumers in need of care who received adequate care according to predetermined standards for the process of care for various functions (i.e.

Effect of inhibitors of the de novo pyrimidine biosynthetic pathway on serum uridine levels in mice.

Since C57BL X DBA F1 (hereafter called BDF1) mice possess a relatively constant concentration of serum uridine [9.7 +/- 1.3 (S.

Induction and development of mouse liver glutathione S-transferase activity.

Mouse liver glutathione S-transferase activity at birth was 1/10 that of adults, and increased steadily with each successive week of age until adult values were reached at 8 weeks. Activity was inducible with phenobarbital; however, the percentage increase in activity was dependent upon substrate. 2 distinct peaks of transferase activity were obtained on CM-cellulose chromatography.
