Malignant papillary lesions of the endometrium.

In a review of 440 patients treated for endometrial adenocarcinoma at this center since 1974, 21 patients with tumors of papillary histology were identified. Eleven (2.5%) lesions contained histologic changes characteristic of uterine papillary serous carcinoma: complex papillary architecture, high nuclear/cytoplasmic ratio, and irregular epithelial tufting.

Discovery and development of a novel class of nonsteroidal aromatase inhibitors.

Efforts to develop a novel class of nonsteroidal aromatase inhibitors began with the discovery that the infertility in male rats exposed to high levels of the agricultural fungicide, fenarimol (alpha-(2-chlorophenyl)-alpha-(4-chlorophenyl)-5-pyrimidine-methanol), was attributable to the inhibition of aromatase activity within the central nervous system during the critical neonatal period. Although fenarimol was not particularly potent in inhibiting rat ovarian microsome aromatase activity in vitro (50% inhibition (IC50) = 4.1 microM).

Primary carcinoma of the fallopian tube: evidence for activity of cisplatin combination therapy.

The records of 23 patients with confirmed carcinoma of the fallopian tube, treated between 1966 and 1983, were reviewed. Patients ranged in age from 41 to 88 years. A pelvic mass was the most common preoperative finding (61%), followed by abnormal bleeding (43%), and pain (39%).

Differences between acute and long-term metabolic and endocrine effects of oral beta-adrenoceptor agonist therapy with pirbuterol for cardiac failure.

The metabolic, hormonal and haemodynamic effects of oral pirbuterol, a new beta 2-adrenoceptor agonist, were studied acutely (n = 19) and after 3 months treatment (n = 11) in patients with severe heart failure receiving chronic frusemide therapy. In the acute study fasted patients (n = 10) showed reductions in plasma K+ (P less than 0.005) and cortisol (P less than 0.

Untreated heart failure: clinical and neuroendocrine effects of introducing diuretics.

The clinical and neuroendocrine response to diuretic treatment was assessed at rest and on exercise in 12 patients with heart failure. Before treatment all patients were limited by breathlessness on exercise; one was oedematous. Plasma renin activity and aldosterone were normal but plasma noradrenaline was raised both at rest and on exercise.

Ovarian carcinoma with extracellular mucin production: reassessment of "pseudomyxoma ovarii et peritonei".

Peritoneal implants of mucin and columnar epithelium with variable amounts of free peritoneal mucin complicated 11 mucinous ovarian neoplasms. Slides of the primary ovarian tumors were reviewed in eight cases. Although all contained areas of mucinous cystadenomatous tumor of low malignant potential, the neoplasms displayed additional features not well recognized as manifestations of invasive disease in the ovary.

Imipenem pharmacokinetics in elective colorectal surgery.

A study of the pharmacokinetics of imipenem in 22 patients undergoing elective colorectal surgery was performed. Samples of plasma, fat, muscle and viscera were assayed at various intervals following intravenous injection of 1 g imipenem and 1 g cilastatin. The concentration of imipenem in plasma was approximately ten times that found in the tissues.

Estrogen and progesterone receptors in uterine sarcomas.

Estrogen and progesterone receptors were measured in tissues from 43 patients with various uterine sarcomas using the dextran-coated charcoal assay. Estrogen receptor was present in 55.5% and progesterone receptor in 55.

The renal response to neuroendocrine inhibition in chronic heart failure: double-blind comparison of captopril and prazosin.

Activation of the renin-angiotensin and sympathetic systems in chronic heart failure causes important renal vasoconstriction. In a double-blind cross-over study, treatment with captopril for one month reduced systemic and renal vascular resistance by 14% and 25%, increased renal blood flow by 12%, and increased the percentage of the cardiac output perfusion to the kidney by 13%. Treatment with prazosin for one month also reduced systemic vascular resistance by 8%, renal vascular resistance increased by 20%, and renal blood flow and the percentage of the cardiac output going to the kidney fell by 14% and 26%.

Classification by race and Spanish origin in the 1980 census and its impact on white and nonwhite rates.

A basic change concerning the racial classification of persons of Spanish origin used in the 1980 U.S. census is examined for its impact on white and nonwhite population counts, particularly in urban areas.

Adenocarcinoma corpus et colli: analysis of diagnostic variables.

Between January 1973 and December 1983, 469 patients with carcinoma of the endometrium were seen at this institution. Eighty-one patients were identified with adenocarcinoma involving both the uterine body and the cervix. Patients were divided into three groups for evaluation.

Does non-clinical decompression stress lead to brain damage in abalone divers?

Abalone divers are subject to considerable decompression stresses and could be at risk of progressive cognitive impairment. A sample of abalone divers was compared with a sample of fishermen, by means of a battery of neuropsychological tests. No evidence of cognitive impairment was found in the divers, in spite of evidence of their exposure to decompression stress.

Vasodilatation with captopril and prazosin in chronic heart failure: double blind study at rest and on exercise.

A double blind cross over study was performed to compare the long term hormonal, haemodynamic, and clinical responses to specific inhibition of the renin-angiotensin-aldosterone system (captopril) and of the alpha 1 adrenoceptors of the sympathetic system (prazosin) both at rest and during upright exercise in patients with chronic heart failure. Sixteen patients completed one month's treatment with each drug. During conventional diuretic treatment (control) plasma renin activity, aldosterone, and noradrenaline were increased at rest and on exercise.

Estrogen and progesterone receptors in epithelial ovarian malignancies.

Cytoplasmic estrogen receptor levels (ER) were measured in ovarian epithelial malignancies from 44 patients using a dextran-coated charcoal assay with analysis of the data by Scatchard plots. In 31 cases, progesterone receptor levels (PR) were also determined. In untreated patients, 68.

Adriamycin chemotherapy for malignant mixed mesodermal tumor of the ovary. A Gynecologic Oncology Group Study.

Malignant mixed mesodermal tumor (MMMT) of the ovary is a rare, but usually fatal, cancer for which there exists no proven postsurgical therapy. The Gynecologic Oncology Group has evaluated adriamycin in this disease at a dose of 75/m2. Among 10 evaluable cases with measurable disease there was one partial response and no complete responses.

Villous adenoma of the uterine cervix associated with invasive adenocarcinoma: a histologic, ultrastructural, and immunohistochemical study.

An unusual neoplasm of the uterine cervix had the features of a villous adenoma with an adjacent adenocarcinoma. Histologic and electron microscopic features of the lesion are described, as well as immunohistochemical staining of the lesion for carcinoembryonic antigen. Electron microscopic evidence of intestinal differentiation in the villous adenoma suggests a rarely recognized potential for intestinal metaplasia in the uterine cervix.

Group B streptococcal necrotizing fasciitis arising from an episiotomy.

A case of extensive necrotizing fasciitis arising from an episiotomy is presented. Group B beta-hemolytic streptococcus and Staphylococcus aureus were isolated. Prompt recognition and aggressive therapy resulted in a favorable outcome despite significant morbidity.

Abdominal sacral colpopexy with Mersilene mesh in the retroperitoneal position in the management of posthysterectomy vaginal vault prolapse and enterocele.

During a 12-year study period from 1972 to 1984, 56 patients underwent abdominal sacral colpopexy with retroperitoneal interposition of a suspensory hammock between a prolapsed vaginal vault and the anterior surface of the sacrum. They were followed from 6 months to 12 1/2 years, and constitute the basis of this report. In most patients, a synthetic mesh was the material interposed.

Mitoxantrone (NSC 301739) in patients with advanced cervical carcinoma. A phase II study of the Gynecologic Oncology Group.

Twenty-six evaluable patients with advanced or recurrent squamous cell carcinoma of the uterine cervix were treated with mitoxantrone at a dosage of 12 mg/m2 every 3 weeks. Twenty-five of 26 patients had had prior irradiation and 24 prior chemotherapy. There were two partial responses, one in a patient with pelvic recurrence and another in a patient with a right upper quadrant mass.

Second-look laparotomy after chemotherapy in the management of ovarian malignancy.

Eighty-eight patients with ovarian malignancy underwent second-look laparotomy as part of their plan of management at Indiana University Hospital. Thirty-five patients (39.8%) were found to have no gross or microscopic evidence of persistent neoplasm, and an additional 16 (18.

Clinical importance of the renin-angiotensin system in chronic heart failure: double blind comparison of captopril and prazosin.

Nineteen patients with chronic heart failure participated in a double blind crossover trial of captopril and prazosin--two drugs with differing neuroendocrine effects--to determine whether neuroendocrine changes could explain clinical and haemodynamic responses to treatment. Patients were assessed before and after acute and long term (four weeks') treatment with each drug given in random order. Sixteen patients completed the study.

Radiography of the small bowel in patients with gynecologic malignancies.

The records and radiographs of 284 patients with gynecologic malignancy were reviewed to determine the incidence and nature of small-bowel abnormalities. Seventeen percent of the patients had small-bowel studies. Twenty-four percent of patients with ovarian cancer had radiologic examination of the small bowel, and in almost all cases the abnormalities were due to metastatic disease.
