Health check-up program for pre/postmenopausal women at Siriraj Menopause Clinic.

OBJECTIVE: To determine the general health status of pre/postmenopausal women attending the menopause clinic. STUDY DESIGN: Retrospective descriptive study. SETTING: Siriraj Menopause Clinic, Gynecologic Endocrinology Unit, Division of Reproductive Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. Study population: Pre/postmenopausal women (i) presumed to have no medical disease (no disease group) or (ii) with unknown status of medical disease (no record group) and undergoing health check-up program at the time of registration without prior hormone therapy. MATERIAL AND METHOD: Medical records of new patients registering at the menopause clinic from January 1999 to December 2005 were reviewed. RESULTS: Among 1,020 patients undergoing health check-up program, there were 366 patients in the no disease group. They had abnormal health parameters listing by frequency of prevalence including hypercholesterolemia (62.3%), suboptimal blood pressure (49.3%), overweight to obese (30.2%), suboptimal fasting blood sugar (2 7.9%), hypertriglyceridemia (21.3%), abnormal liver function tests (5.4-6.9%), and abnormal kidney function tests (0.5%). The prevalence of dyslipidemia was statistically higher in the no record group compared to the no disease group; such abnormal parameters included hypercholesterolemia (> or =200 ml/dL), high blood level of low density lipoprotein cholesterol (LDL-C > or = 130 mg/dL), and high ratio between LDL-C and high density lipoprotein cholesterol (LDL-C/HDL-C ratio >3). Osteoporosis was found in 6.6% of the patients. Abnormal mammographic findings that needed close follow-up or breast biopsy were found in 13.5%. Twelve patients had breast biopsy and none had breast cancer. CONCLUSION: Abnormal health parameters are common in pre/postmenopausal women presumed to have no medical disease. The similar or even worse findings are also found in those whose status of medical diseases was unknown. Therefore, a routine health screening program, especially for metabolic diseases, should be offered to pre/postmenopausal women regardless of their medical history.

Serum follicle stimulating hormone and estradiol in peri/postmenopausal women attending Siriraj Menopause Clinic: a retrospective study.

OBJECTIVES: To determine serum levels of Follicle Stimulating Hormone (FSH) and Estradiol (E) in peri/postmenopausal women attending the menopause clinic. STUDY DESIGN: Retrospective descriptive study. SETTING: Siriraj Menopause Clinic, Gynecologic Endocrinology Unit, Division of Reproductive Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital. Study population: Peri/postmenopausal women attending Siriraj Menopause Clinic from January 1994 to December 2003. MATERIAL AND METHOD: Medical records of women who had a blood test for FSH and/or E2 prior to hormonal therapy were reviewed. RESULTS: During a 10 year period, there were 116 eligible patients who could be classified into perimenopausal (31 cases), natural postmenopausal (43 cases), and surgical postmenopausal (32 cases) groups. Age at registration of perimenopausal (47.87 +/- 4.38 yr) and surgical postmenopausal (48.06 +/- 6.49 yr) groups were younger than that of the natural postmenopausal group (55.74 +/- 6.80 yr). The perimenopausal group, who still had regular menstruation, was the youngest. The average FSH level of 60.46 +/- 33.15 mIU/mL was not different among groups. The estradiol level of perimenopausal (79.05 +/- 83.62 pg/mL) and surgical postmenopausal (63.05 +/- 136.39 pg/mL) groups were significantly higher than that of natural postmenopausal (25.05 +/- 37.663 pg/mL) group (p = 0.001). Serum level of FSH or E2 was not correlated with age or years since menopause. There was significant but minimal negative correlation between serum levels of FSH and E2. CONCLUSION: Serum FSH and/or E2 levels are not accurate enough by themselves to rule in or rule out perimenopause. The authors suggested that clinicians should diagnose perimenopause based on menstrual history and age, without relying on laboratory testing.

Distal radius bone mineral density and grip strength in peri/postmenopausal Thai women.

To determine the relationship between distal radius bone mineral density (BMD) and grip strength (GS) in peri/post menopausal Thai women. 177 healthy volunteers, > or = 40 years old, were included. Distal radius BMD of the non-dominant side was measured using dual energy X-ray absorptiometry. GS of both dominant and non-dominant sides was measured using a Jamar dynamometer. The association between BMD and GS was determined by correlation analysis. Other factors possibly affecting the BMD or GS including age, years since menopause (YSM), body weight (BW), height (Ht) and body mass index (BMI) were analyzed by the multiple regression method. It was found that BMD had statistically significant but weak, positive correlation to GS (r = 0.262, p < 0.001 for the dominant side, r = 0.193, p < 0.001 for non-dominant side). Age and YSM had a negative correlation, whereas, BW and Ht had a positive correlation to either BMD or GS. After multiple regression analysis, the significant predictors of BMD were age and BW, of dominant GS were age and Ht, and of non-dominant GS was YSM. In conclusion, decrements in distal radius BMD and in GS were found in peri/postmenopausal women. Aging seems to be the most important factor for these features. Although the GS has statistically significant correlation to the corresponding BMD, the clinical significance might not be obvious. Furthermore, the stronger correlation of BMD to the contralateral dominant GS than to the ipsilateral non-dominant GS implies that the influence of muscular strength on BMD, if present, is not due to a direct effect in this age group.

p53 tumor suppressor gene mutation in ovarian cancer in Thai patients.

OBJECTIVES: To characterize molecular mutations of p53 gene in Thai ovarian cancer and compare the mutations with their pathological and clinical findings. MATERIAL AND METHOD: Direct DNA sequencing of hot spot region of p53 gene (exons 5 to 8) from 28 primary ovarian cancer tissues, 2 metastatic tumors and their paired blood samples was performed. The detected mutations were compared to the pathological and clinical findings and responsiveness to treatments after 36 months of follow-up. RESULTS: One insertion and 4 point mutations in exon 5 of p53 gene were found in 5 out of 28 (18%) ovarian cancer patients. There was no mutation in the paired blood samples. The histological types of the detected tumors were 3 endometrioids and 2 serous cystadenocarcinomas. All 5 patients were in stage I to IV disease and showed overall 4 out of 5 (80%) complete response until 36 months after surgery followed by chemotherapy, compared to 14 out of 28 (50%) of complete response in all cases of ovarian cancer. CONCLUSION: The authors found 5 cases of ovarian cancer patients with p53 gene mutations giving the same response to complete standard treatment as all cases. Significant factors affecting responsiveness of these patients depended more on stages, grades and histological cell types of the cancer.

Minor side effects of hormonal replacement therapy in menopausal Thai women.

Objective : To evaluate type and incidence of minor side effects of hormonal replacement therapy (HRT). Design : Cross-sectional, descriptive study. Patients : 114 women, who were follow up at Menopause Clinic in July 2001. Methods: All women were interviewed about their experience in various symptoms possibly related to HRT side effects. The symptoms before and during HRT were recorded. The symptoms that were present only during HRT but not before HRT were considered as side effects. Results : The study showed that breast pain was the most common side effect of both cyclic HRT (40%) and continuous HRT (38.1%) groups; whereas the complaint of weight gain was more pronounced in the estrogen only (31.8%). Conclusion : Although minor side effects of HRT are not life threatening, they may have influence on the compliance of HRT. The incidence of minor side effects of HRT is varied depending on the HRT regimens. However, the symptoms similar to the HRT side effects are already present prior to HRT in a certain number of patients.

A comparison of swim-up and simple swim-up methods for the extraction of high motility sperm.

The objective of this study was to compare two methods for the extraction of high motility sperm; swim-up and simple swim-up technique. The results were comparable in concentration, motility and morphology.

Premature Ovarian Failure (POF): Cytogenetic and SRY analyses.

Premature ovarian failure (POF) is a condition causing amenorrhea, hypoestrogenism and elevated gonadotropins and can be found in 1% of women before the age of 40. There are many causes of POF. One of these is a chromosome abnormality especially of the sex chromosome, the most common of which is 45,X. Translocation between regions on the X and Y chromosome and X chromosome deletions have also been reported. The objectives of this study were to perform chromosome analysis and to look for the SRY gene in the patient with POF. 25 patients with POF attending the Gynecologic Endocrinology Clinic at the Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, were included in this study. Peripheral blood was collected from the patients for cytogenetic and SRY analyses. There were 4 patients (16%) with identifiable abnormal X chromosomes, which were 45,X/46,XX ; 46,X,i(Xq) ; 46,XX/47XXX and 47,XXX. All patients were SRY negative. POF may be caused by other causes such as auto-immunity, mumps oophoritis etc. Interestingly, this study revealed much higher chromosome abnormalities rate among Thais with POF than has been previously reported elsewhere although those chromosome anomalies are very similar. Chromosome study should be routinely performed as a part of basic laboratory evaluation for all patients with POF. The information obtained will be useful for genetic counseling, planning patient management and family members' decisions in the future.

Assessment of fetal lung maturity by multiple testing with shake test, tap test and OD 650.

Assessment of fetal lung maturity is of great importance in obstetric practice to plan for the future care and proper time for termination of pregnancy. At present, there are many methods used for screening for fetal lung maturity. A good screening test should be simple, easy to perform, rapid, inexpensive and be sensitive and specific. This study was a comparative study of fetal lung maturity assessment by using multiple testing: shake test, tap test and OD 650. These three tests were performed simultaneously and interpreted within 10-15 minutes. The results were compared with lecithin and sphingomyelin ratio (L/S ratio) which was used as the gold standard. L/S ratio > 2 was interpreted as “mature” in this study. Aminotic fluid samples wee obtained from women with uncomplicated pregnancies who underwent amniocentesis for fetal lung maturity testing with consent. All samples were uncontaminated by blood or meconium. The results, analysed from 185 samples studied, showed that the shake test, tap test and OD 650 gave a sensitivity of 79.3%, 87.1%, 76.6% and a specificity of 60.0%, 45.0% and 54.2% respectively, which were not statistically different (P>0.05, Cochran’s test). Screening for maturity using two or more tests gave a sensitivity of 82.7% and a specificity of 55.8% which were also not statistically different when compared with each test. In conclusion, shake test, tap test or OD 650 can be easily used as a simple and sensitive screening method for fetal lung maturity. Multiple testing, performing all three tests simultaneously, did not increase the sensitivity or specificity of the test and is not recommended. The choice of test at a screening method is therefore up to individual preference of depends on facilities available.

Long-term compliance with hormonal replacement therapy: Experience of Siriraj menopause clinic.

A retrospective analysis of women who registered for treatment at Siriraj Menopause Clinic in the year 1995 was performed to assess long-term compliance with hormonal replacement therapy (HRT). There were 217 women who registered that year and all were followed up for the following four years. Of these 217 women, 195 commenced HRT and were divided into two groups. The first group of 1,105 women (natural menopause, N) comprised 25 menopause transition and 80 postmenopause cases. The second one of 91 women (surgical menopause, S) was the group who previously underwent total hysterectomy with bilateral salpingooophorectomy. The average age at first consultation in the N group was 52.1 + 6.5 year which was significantly higher than 46.7 + 7.7 year in the S group (P<0.0001). In the N group, compliance was 61.9% at 1 year and 56.1%, 50.4%, 43.8% at 2,3 and 4 years while in the S group compliance was 74.7% at 1 year and 64.8%, 58.2%, 47.2% at 4 years respectively. Compliance with HRT was not statistically different between both groups (P>0.05). Drop out cases were maximum in the first years in both groups and total drop out cases increased slowly and steadily every year for the next four years. Ages at first consultation of compliant and non compliant women in each group were also not statistically different (P>0.05). Long-term compliance with HRT in this study was comparable with previously reported data. Main reasons for non compliance at 4 years were breast symptoms including breast masses and mastalgia, abnormal vaginal bleeding or irregular menses, weight gain and skin problems including acne, melasma and hair loss. These problems are different from other reports. Factors affecting long-term compliance with HRT should be further studied especially in those women who have undergone a surgical menopause.

Comparison of three methods for DNA extraction from amniotic fluid for fetal sex determination by multiplex polymerase chain reaction (PCR).

The objective of this study was to compare three methods used for amniotic fluid DNA extraction. These methods were: Proteinase K/Phenol-Chloroform, Proteinase K/7.5M Guanidine-HCl and DNAzolา BD Reagent. Ten samples of uncontaminated amniotic obtained by amniocentesis performed in mothers with advanced maternal age for detection of fetal chromosome abnormality were studied. Each sample was divided into three tubes, 1 ml placed in each, and DNA extraction was performed by all three methods. The quality and quantity of DNA extracted by each method were compared by electrophoresis on 3% agarose gel and spectrophotometric study at 260 & 280 nm. The DNA obtained was subsequently used for fetal sex determination by multiplex PCR method. The primers used for multiplex PCR were specific for X and Y chromosomes. Accuracy of fetal sex determination was compared with the results from amniocyte culture and the sex at birth. The results showed that DNA extracted by DNAzolาBD Reagent was 100% accurate when used to determine fetal sex by PCR; eight samples on 1st PCR and the other two on repeat PCR. DNA extracted by Proteinase K/7.5M Guanidine-HCl also yielded 100% accuracy in fetal sex determination; seven samples on 1st PCR, two samples on 2nd PCR and one sample needed 3rd PCR. The Proteinase K/Phenol-Choroform method yielded only 90% accuracy and one sample failed to determine fetal sex after having repeated PCR three times. The extraction method which gave the maximum amount of DNA was the Proteinase K/Phenol-Chloroform one but the failed to give 100% accuracy in determining fetal sex. The method which produced the least protein contamination was DNAzolฎBD Reagent and gave 100% accuracy in determining fetal sex with smallest number of PCR reactions. In conclusion, DNAzolฎBD reagent method is relatively rapid for amniotic fluid DNA extraction with high accuracy for fetal sex determination but when large amount of DNA is also needed for other purposes, Proteinase K/Phenol-Chlorofrom is recommended as the method of choice.
