Efficacy and safety of iodine in the postpartum period in an area of mild iodine deficiency.

BACKGROUND: Iodine deficiency (even moderate) plays a major role in pregnancy associated goiter development, which is only party reversible after pregnancy. The prevalence of post partum thyroiditis is reported to be slightly lower in areas of iodine deficiency. Thus iodine supplementation may be effective in decreasing pregnancy associated increase in thyroid volume, but enhances the risk of increasing the prevalence of thyroid dysfunction in the post partum period. Therefore, we evaluated the effect of iodine supplementation (with two different doses: 50 microg and 250 microg) on the prevalence of post partum thyroiditis and the decrease in thyroid volume up to 8 months post partum in an area of mild iodine deficiency. PATIENTS AND METHODS: Thyroid volume of 56 women was evaluated 5 days and 3 months after delivery (study I). In an intervention study (Study II) 70 women were randomized to receive 50 or 250 microg of potassium iodide for a period of 8 months post partum beginning five days after delivery. Thyroid volume, the echogenecity of the thyroid gland, thyroid hormone parameters (T4, T3, fT4, TSH) and thyroid antibodies (TPO and Tg-Ab) were measured 5 days, 3 and 8 months after delivery. RESULTS: A total number of 11 women developed postpartum thyroid dysfunction: 4 women developed manifest thyroid dysfunction (3 hyperthyroidism and 1 hypothyroidism) 3 months post partum. The remaining seven had subclinical hypo- or hyperthyroidism. All changes were clinically mild and transient as evidenced by normalization of thyroid hormone parameters on reexamination at 8 months. Among the eleven, 6 women in the 50 microg iodine group and 5 women of the 250 microg iodine group developed thyroid dysfunction, suggesting that the iodine dose did not affect post partum thyroiditis. The administration of only 50 microg iodine was associated with a significant fall of thyroid size already 3 months after delivery (25.4 +/- 1.5 ml (mean +/- sem) to 18.2 +/- 1.25 p <0.001). The application of 250 microg iodine was equally effective. 8 months post partum a slight but further decrease could be demonstrated. On the other hand, in study I no significant reduction in thyroid volume was observed in women receiving no supplementary iodine (thyroid volume at delivery 29 +/- 2.2 ml; at 3 months 27.5 +/- 3.0 ml. CONCLUSION: The administration of supplementary iodine (up to 250 microg) to an unselected population, residing in an area of mild iodine deficiency, in the post partum period is save as indicated by a prevalence of 5.7% manifest thyroid dysfunction. These changes are clinically mild and transient. Even the amount of 50 microg of iodine supplementation seems to by very efficient in reducing pregnancy associated increments in thyroid volume.

Screening for gestational diabetes mellitus: comparison of a glucose polymer and a glucose monomer test beverage.

BACKGROUND: The current test for gestational diabetes mellitus (GDM) uses a glucose monomer test beverage, which frequently causes gastrointestinal symptoms, and venipuncture. We investigated a simplified test using a beverage of glucose polymer and a capillary whole blood glucose measurement. METHODS: In a randomized, double-blind clinical trial, women at 24 to 28 weeks' gestation received a 50-g glucose monomer (n = 41) or glucose polymer (n = 35) beverage. Venous and capillary blood samples were obtained 1 hour later. The women then completed standardized questionnaires about their symptoms. RESULTS: The glucose polymer beverage was associated with significantly fewer symptoms than was the glucose monomer drink: the mean was 1.1 symptoms per test with the glucose monomer drink and 0.4 symptoms per test with the glucose polymer drink (P less than 0.05), 51 percent of the women developed symptoms after drinking the glucose monomer beverage, and 27 percent of the women developed symptoms after drinking the glucose polymer beverage (P less than 0.05). Glucose type did not affect the 1-hour plasma glucose level, mean 5.94 mmol/L (107 mg/dL) for the glucose monomer and 5.76 mmol/L (103.8 mg/dL) for the glucose polymer (P = 0.79). For the capillary test, sensitivity was 0.75 and specificity was 0.82 in detecting a screening test positive by the venous plasma glucose criterion. CONCLUSION: The results of this study indicate that a glucose polymer beverage is better tolerated than a glucose monomer beverage during GDM screening, but capillary glucose measurement might be of limited use in clinics where many personnel perform the capillary blood glucose testing.

Relative fitness and frailty of elderly men and women in developed countries and their relationship with mortality.

OBJECTIVES: To investigate the relationship between accumulated health-related problems (deficits), which define a frailty index in older adults, and mortality in population-based and clinical/institutional-based samples. DESIGN: Cross-sectional and cohort studies. SETTING: Seven population-based and four clinical/institutional surveys in four developed countries. PARTICIPANTS: Thirty-six thousand four hundred twenty-four people (58.5% women) aged 65 and older. MEASUREMENTS: A frailty index was constructed as a proportion of all potential deficits (symptoms, signs, laboratory abnormalities, disabilities) expressed in a given individual. Relative frailty is defined as a proportion of deficits greater than average for age. Measures of deficits differed across the countries but included common elements. RESULTS: In each country, community-dwelling elderly people accumulated deficits at about 3% per year. By contrast, people from clinical/institutional samples showed no relationship between frailty and age. Relative fitness/frailty in both sexes was highly correlated (correlation coefficient >0.95, P<.001) with mortality, although women, at any given age, were frailer and had lower mortality. On average, each unit increase in deficits increased by 4% the hazard rate for mortality (95% confidence interval=0.02-0.06). CONCLUSION: Relative fitness and frailty can be defined in relation to deficit accumulation. In population studies from developed countries, deficit accumulation is robustly associated with mortality and with age. In samples (e.g., clinical/institutional) in which most people are frail, there is no relationship with age, suggesting that there are maximal values of deficit accumulation beyond which survival is unlikely.

Effects of chronic iodine administration on thyroid status in euthyroid subjects previously treated with antithyroid drugs for Graves' hyperthyroidism.

In view of the adverse effects of the administration of pharmacological quantities of iodine to euthyroid patients with a history of a wide variety of thyroid disorders, it has been suggested that iodine-containing medications and radioopaque dyes containing iodine should be avoided, if possible, in patients with underlying thyroid disease. We have now prospectively studied the effects of pharmacological doses of a saturated solution of potassium iodide (SSKI) on thyroid function in euthyroid patients with a previous history of hyperthyroid Graves' disease successfully treated with antithyroid drugs. Ten euthyroid women (mean age, 56 yr) who had hyperthyroid Graves' disease successfully treated with methimazole 36.4 +/- 4.7 months earlier were evaluated before, during, and after the administration of 10 drops SSKI daily for 90 days. The following thyroid function tests were obtained: serum T4, T3, TSH, TSH receptor antibody (TSH-RAb), and antithyroid peroxidase antibody (AbTPO) concentrations; TRH tests; and iodine perchlorate discharge tests. Serum T4, T3, basal and TRH-stimulated TSH, and TSH-RAb values were normal before SSKI administration, but serum AbTPO levels were markedly positive in 7 and iodine perchlorate discharge tests were positive in 4 of these 10 women. During SSKI administration, basal and TRH-stimulated serum TSH values increased above normal in 2 women with normal serum T4 and T3 concentrations; thyroid hormone values and TRH tests were normal in the other 8 patients and similar to values observed in 4 euthyroid women without a history of thyroid disease given SSKI. Serum AbTPO increased slightly, but significantly, during SSKI administration in the 7 women with positive values at baseline (P < 0.05). TSH-RAb remained undetectable. After SSKI withdrawal, the 10 women were reevaluated 60 and 120 days later. Two women developed a blunted TSH response to TRH, but normal serum T4 and T3 concentrations, and 2 women developed overt hyperthyroidism, with undetectable basal and TRH-stimulated serum TSH and elevated serum T4 and T3 concentrations, requiring methimazole therapy. All values in the remaining 6 women were similar to those present before SSKI administration. These results suggest that some euthyroid patients with a history of antithyroid drug therapy for Graves' disease may develop thyroid dysfunction during and after excess iodine administration. The development of subclinical hypothyroidism during SSKI administration was not clinically important, but the occurrence of overt hyperthyroidism after SSKI was discontinued did require antithyroid drug therapy. It is advisable, therefore, to avoid iodine-containing substances in euthyroid patients with a history of antithyroid drug therapy for Graves' disease.

Utility of the in situ detection of HPV in Pap smears diagnosed as within normal limits.

OBJECTIVE: To determine the clinical significance in normal Pap smears of HPV detection as determined by Hybrid Capture (HC) and in situ hybridization analyses. STUDY DESIGN: We studied 135 consecutive Pap smears as well as 46 other smears from high-risk patients each initially diagnosed as within normal limits. RESULTS: The 135 "normal" Pap smears were rescreened, and 6 (4%) where found to be either ASCUS or SIL. In the remaining 129 cases, HPV DNA was detected in 0% and 9%, respectively, using in situ hybridization and HC I. Upon rescreening the high-risk patients, nine (20%) were reclassified as having SIL/ASCUS; each was in situ hybridization positive, and eight were HC positive; six (67%) of these women developed SIL on follow-up. In the 37 Pap smears in high-risk women still within normal limits after manual rescreening, HPV was detected in 2% by in situ hybridization and 46% by HC; 6% of the HC-positive women developed SIL on follow-up. CONCLUSION: In situ hybridization rarely detects HPV in Pap smears diagnosed as within normal limits after manual rescreening. In situ hybridization is very effective in detecting rare, atypical cells in Pap smears diagnosed as within normal limits and, in a high-risk population, is predictive of SIL on clinical follow-up.

Self-development for women in the NHS.

Training in the NHS in many careers, including nursing, does not routinely include preparation for management. This article looks at how a group of women in different disciplines in one NHS trust used the Astra programme from the equal opportunities unit at the NHS Executive as a means of developing their managerial careers. After taking part in the four-month programme, participants reported greater self-confidence, increased assertiveness and a greater sense of clarity about this career development.

Acceptability of voluntary HIV testing by pregnant women in developing countries: an international survey. Ghent International Working Group on Mother-to-Child Transmission of HIV.

OBJECTIVE: To evaluate acceptability of voluntary HIV counselling and testing (VCT) by pregnant women in the context of clinical trials assessing interventions to reduce mother-to-child transmission (MCT) of HIV in developing countries. METHODS: During September-October 1997, 13 studies located in West (Abidjan, Bobo Dioulasso), East (Nairobi, Mombasa, Dar Es Salaam, Blantyre, Lusaka, Harare) and South Africa (Soweto, Durban), and Thailand (Bangkok) were included in a cross-sectional mailing survey about the acceptability of VCT in antenatal clinics. Acceptance rate, return rate, overall acceptability of VCT (acceptance of both pre- and post-VCT sessions) were obtained using a standardized questionnaire. RESULTS: The median overall acceptability of VCT was 69% (range, 33-95%). Overall acceptability of VCT most frequently depended on return rates because acceptance rates were generally high. Where several studies were conducted in parallel in the same city or the same country, overall acceptability rates of HIV testing were generally comparable even if the intervention programmes differed. Overall acceptability rates of VCT were high in antenatal clinics where a particular effort in implementing VCT programmes had been made. CONCLUSIONS: This international survey shows that despite many obstacles, VCT is feasible and acceptable for pregnant women aiming to reduce their risk of transmitting HIV to their children.

The risk of developing urinary stress-incontinence after vaginal repair in continent women. A clinical and urodynamic follow-up study.

A study was performed to find out how often continent women develop urinary stress-incontinence after a Manchester operation for genito-urinary prolapse, and to ascertain whether factors in the selection of patients, or steps in the surgical procedure are responsible for producing stress-incontinence postoperatively. Seventy-three of 102 consecutive patients were continent before operation. Sixteen of the 73 women (22%) became stress incontinent. Advanced age increased the risk of developing urinary stress-incontinence. Twenty-five per cent of the women more than 60 years old developed stress-incontinence, but only 1 of 13 below the age of 60. Preoperative urethral closure pressure was significantly lower in those developing urinary stress-incontinence, and closure pressure was further reduced by surgery in this group, significantly more than in the women remaining continent. Surgery significantly reduced the pressure transmission ratio in the patients who developed urinary stress-incontinence, and less in the continent ones. The preoperative pressure transmission ratio, however, was not related to the risk of developing urinary stress-incontinence after the operation. The urodynamic examinations pre- and postoperatively demonstrated important changes in the urodynamic parameters produced by the Manchester procedure, but did not prove useful in determining which patients will develop urinary stress-incontinence.

Survey of the deliveries of immigrant women from developing countries in the 2nd Institute of Gynaecology and Obstetrics, University of Rome, 'La Sapienza', Italy.

Five hundred and forty-four immigrant women, admitted from 1983 to 1993 to the 2nd Institute of Obstetrics and Gynaecology of Rome University, were enrolled in the study. Africa and East Europe were the most common places of birth. Seventy-five per cent of women gave birth spontaneously, and a caesarean section was performed in 22.2%. The frequency of spontaneous delivery and caesarean section was about the same among Italian and immigrant women.
