Objectives: To assess the effect of a vaginal ring delivering estradiol and progesterone in postmenopausal women and to determine whether continuous administration can relieve climacteric symptoms, produce an acceptable pattern of vaginal bleeding and control endometrial proliferation.

Methods: Twenty-nine postmenopausal women with an intact uterus were studied. All had climacteric symptoms. The vaginal rings contained 0.36 g estradiol and either 3.6 g progesterone (high dose progesterone) or 1.8 g (low dose progesterone), and were kept in place for 4–6 months. Serum progesterone, estradiol and estrone were measured and endometrial thickness determined. All women kept a daily diary of bleeding/spotting and completed a questionnaire on climacteric symptoms at monthly intervals. The low dose progesterone group comprised 14 women and the high dose progesterone group 15 women.

Results: A total of 18 patients (9 in each group) completed the study. Mean levels of estradiol, estrone and progesterone were at their peak after 2 to 4 weeks. All rings were effective in alleviating vasomotor symptoms, although there was evidence of the "escape from effect" in month 6. Endometrial thickness increased in 6 of the 29 women but biopsy in each case showed no evidence of hyperplasia. Of the 18 women who completed the study, 5 had amenorrhea throughout, 7 had amenorrhea after 3 months, and the remainder had one or two bleeding episodes after 3 months. Therapy was discontinued in 11 women.

Conclusions: A vaginal ring delivering estradiol and progesterone controlled climacteric symptoms, prevented endometrial proliferation, and provided an acceptable bleeding pattern. It should be viewed as a promising alternative for short-term estrogen-progesterone therapy.

Background: Anemia is a known risk factor for ischemic heart disease. Based on knowledge of the physiologic role of oxygen delivery to the myocardium, anemia may be a cause of more severe cardiovascular diseases or a marker of other processes occurring in the body that induce more severe disease.

Objectives: To investigate the relationship between anemia and the clinical picture of IHD[1], including manifestations, severity and complications.

Methods: The population studied comprised 417 similarly aged patients with IHD and anemia. The patients were categorized into subgroups of IHD according to disease severity: namely, angina pectoris, acute ischemia, acute myocardial infarction, congestive heart failure or cardiac arrhythmias. Two populations served as control groups: patients with anemia but no IHD (C-I) and patients with IHD without anemia (C-II). A standard anemia workup was conducted in all patients with IHD and anemia and a correlation was made between the hematologic parameters and the manifestations and complications of IHD.

Results: The common presenting symptom was chest pain in the study group and in C-II (94% and 86% respectively) and weakness (90%) in C-I. Patients with IHD and anemia tended to suffer from a more advanced degree of IHD (80%) compared to patients with IHD alone who had milder disease (46%). Hematologic values including hemoglobin, mean cell volume, serum iron and total iron binding capacity correlated inversely with disease severity among anemic patients with IHD. There were significant differences between the study group and C-II regarding CHF[2] (31% and 18% respectively) and arrhythmias (41% and 16% respectively). The mortality rate was higher in patients with IHD and anemia than in patients with IHD alone (13% and 4% respectively).

Conclusions: Anemia is a significant risk factor in IHD. It correlates with advanced IHD, CHF, rhythm disturbance and higher mortality rate. An aggressive therapeutic and preventive approach might improve the outcome of this disease.

Background: The precise genes involved in conferring prostate cancer risk in sporadic and familial cases are not fully known.

Objectives: To evlauate the genetic profile within several candidate genes of unselected prostate cancer cases and to correlate this profile with disease parameters.

Methods: Jewish Israeli prostate cancer patients (n=224) were genotyped for polymorphisms within candidate genes: p53, ER, VDR, GSTT1, CYP1A1, GSTP1, GSTM1, EPHX and HPC2/ELAC2, followed by analysis of the genotype with relevant clinical and pathologic parameters.

Results: The EPHX gene His113 allele was detected in 21.4% (33/154) of patients in whom disease was diagnosed above 61 years, compared with 5.7% (4/70) in earlier onset disease (P < 0.001). Within the group of late-onset disease, the same allele was noted in 5.5% (2/36) with grade I tumors compared with 18% (34/188) with grade II and up (P = 0.004). All other tested polymorphisms were not associated with a distinct clinical or pathologic feature in a statistically significant manner.

Conclusions: In Israeli prostate cancer patients, the EPHX His113 allele is seemingly associated with a more advanced, late-onset disease. These preliminary data need to be confirmed by a larger and more ethnically diverse study.

Background: The treatment of patients with recurrent ovarian carcinoma after failure of first and second-line chemotherapy is still debated. Chemical agents used for third and fourth-line therapy usually yield poor results with severe toxic side effects.

Objective: To summarize our experience with goserelin in the treatment of patients with recurrent ovarian cancer.

Methods: From September 1996 to June 1999 we administered goserelin, 3.6 mg subcutaneously every 4 weeks, to 15 patients with advanced and recurrent epithelial ovarian cancer (median age 59.0, median performance status 3.0).

Results: Seven of 15 eligible patients relapsed after platinum-based chemotherapy (3 of them also received paclitaxel and another 2 received tamoxifen). Four patients relapsed after carboplatin and paclitaxel, one of whom was treated with topotecan thereafter. Two patients relapsed after single-agent paclitaxel. Two patients with advanced disease and poor performance status without previous treatment received only goserelin. There was one complete response (6.7%) and 1 partial response (6.7%) lasting 8 and 14 months respectively (overall response rate 13.4%). In addition, the disease stabilized in three patients (20%) for a median of 7.5 months. In 10 patients the disease progressed. There was no significant toxicity. Median survival of all patients was 5.8 months.

Conclusion: Goserelin was helpful in one-third of our patients with advanced and refractory ovarian cancer. It is an easy and non-toxic option for treating very ill or previously heavily treated patients.
 

Background: Visual interpretation of fetal heart rare monitoring is subject to intra and inter observer variability.

Objective: To examine the effect of intrapartum administration of meperidine and promethazine on fetal heart activity measured by a computerized system.

Methods: Fourteen healthy women with normal pregnancies at term were studied during the active phase of labor. Fetal heart rate was recorded with the Oxford Sonicaid system 8000. Recordings were performed for 40 minutes prior to and after maternal intravenous administration of meperidine 50 mg with promethazine 25 mg.

Results: The combination of meperidine and promethazine caused a significant decrease in the number of accelerations of 10 beats per minute (9.7 versus 2.6, P = 0.002) and 15 beats per minute (5.2 vs. l.4, P = 0.003), time spent in episodes of high variation (14.8 vs. 2.0, P = 0.005) and short-term variation (7.8 vs. 5.0, P = 0.003). On the other hand there was an increase in the time spent in episodes of low variation (5.3 vs. 19.7, P = 0.009).

Conclusions: Maternal administration of meperidine with promethazine has a significant effect on FHR[1] indices during the active phase of normal labor.
