Family planning knowledge, attitudes and practices in women with schizophrenic spectrum disorders

This study set out to test three hypotheses about family planning in women with schizophrenic spectrum disorders, as compared to demographically comparable non-mentally ill control women: that they (1) report at least as much unprotected intercourse while not desiring pregnancy; (2) have less knowledge about contraception; and (3) perceive more, and different, obstacles to obtaining or using birth control. A semistructured Family Planning Interview was administered to subjects (n = 44) with Research Diagnostic Criteria diagnoses of schizophrenia and schizoaffective disorder, and to non-mentally ill control subjects (n = 50). The participants had high rates of unprotected intercourse, as did non-mentally ill controls. They had significantly less reproductive and contraceptive knowledge than the control subjects, and were more likely to perceive birth control as difficult to obtain. The most common reason women with schizophrenic spectrum disorders gave for failing to use birth control was that they did not expect to have sex, while that given by non-mentally ill subjects related to side-effects of birth control. Important obstacles to family planning in women with schizophrenic spectrum disorders include relative lack of knowledge and difficulty planning ahead. Although many women with schizophrenia could benefit from long-acting, reversible contraception, many may be unaware of those options and/or may find them difficult to obtain. Integrating family planning with mental health care might better address the unique needs of this population.

Emergency department-based study of risk factors for acute injury from domestic violence against women

STUDY OBJECTIVES

To evaluate the associations between selected socioeconomic risk factors and acute injury from domestic violence against women.

METHODS

We conducted a preliminary matched case-control study to measure the association of selected predictor variables with acute injury from domestic, violence against women. Patients identified as cases were Hispanic or white female emergency department patients, 16 to 65 years of age, with acute injury sustained from physical assault by an intimate male partner. Cases were selected for inclusion in the study if they reported or admitted acute physical assault by their male partners. Controls were selected from non-case female ED patients so as to represent the base population of the cases and enhance comparability. Two controls were matched to each case. The socioeconomic predictor variables examined were the education level, employment status, history of alcohol abuse, and history of drug abuse of the male partner and the education level and cohabitation status of the female partner.

RESULTS

Forty-six cases were identified and included in the study. The age range was 16 to 51 years (mean, 33 years). There were 26 (57%) Hispanic and 20 (43%) white cases. The strongest predictor for acute injury from domestic violence in these patients was a history of alcohol abuse by the male partner, as reported by the female partner (odds ratio, 12.9). The remaining predictor variables were weakly associated or not associated with domestic violence. One half of the cases stated that their male partners were intoxicated with alcohol at the time of assault.

CONCLUSION

Of the socioeconomic variables examined in this preliminary study, a history of alcohol abuse by the male partner, as reported by the female partner, was the strongest predictor for acute injury from domestic violence. A large-scale, multicenter, ED-based study is needed to clarify the relation between alcohol abuse, other socioeconomic factors, and acute physical assaults against women by their intimate male partners.

The use of vaginal ultrasound to identify copper T IUDs at high risk of expulsion

A total of 235 women who had a TCu 380A IUD inserted had a vaginal ultrasound scan performed to identify if the IUDs were correctly placed in the uterine fundus. Women identified as having a misplaced IUD had it removed. The remaining women were compared to 201 women who had an IUD inserted and had no ultrasound evaluation, matched by age and parity. Women were followed-up for one year. Gross cumulative discontinuation rates and continuation rates were calculated by life table analysis. Comparison between groups was done by the Gehan test. The study group had 34 IUDs removed because they were misplaced according to the established criteria. The expulsion rate was significantly higher in the control group, also influencing the continuation rate which was lower in the same group. Of the 34 women who had their IUD removed because it was not correctly placed, only 22 requested and had another IUD inserted. The removal of IUD determined by an ultrasound to be incorrectly placed significantly decreased expulsion rates. However, many IUDs may have been removed unnecessarily, probably resulting in many women not returning to the clinic or deciding to use another contraceptive method.

Controversy of oral contraceptives and risk of rheumatoid arthritis: meta-analysis of conflicting studies and review of conflicting meta-analyses with special emphasis on analysis of heterogeneity

The authors analyze the heterogeneity present in the combined results of past observational studies that investigated the association between oral contraceptive use and rheumatoid arthritis. The authors also evaluate discrepancies among meta-analyses that focus on the same relation. Of the 15 initially reviewed studies, 10 were selected for this meta-analysis, which also includes a qualitative summary of study characteristics and a critical appraisal of study quality. The authors used the direct method to combine the study results when there was no evidence of heterogeneity and the DerSimonian-Laird method when heterogeneity was present. Using a meta-regression to assess the sources of heterogeneity, the authors weighted summary estimates by sample size and undertook a sensitivity analysis. There was a strong indication of heterogeneity when combining all studies (x2 = 29.34, p = 0.00060) with the source of controls explaining most of the heterogeneity. The most important factor in explaining the differences among the overall summary estimates given by the meta-analyses is that different effect estimates had been selected for the same studies. There is no conclusive evidence of a protective effect of oral contraceptives on the risk of developing rheumatoid arthritis. Consensus is needed on how meta-analyses of observational studies should be conducted.

Parasitic infection among children living in two orphanages in Cairo

Children living in institutions as orphanages are more exposed to intestinal parasitism, since crowding and behavioral pattern contribute greatly to the spread of parasitic infection. The present study was conducted on 100 children living in Ain-Shams and El-Mowassa orphanages, Cairo. Twenty children living under appropriate health conditions were studied as controls. Ages of both groups ranged from 6-12 years. The results of this study revealed that 69/100 (69%) orphanage children were positive for parasitic infection, while 8/20 (40%) control subjects were positive for parasitic infection; the difference was statistically significant. Enterobius vermicularis was the commonest parasite among both groups. Other parasitic infections detected were; Giardia lamblia, Entamoeba histolytica, Hymenolepis nana and Entamoeba coli with a prevalence of 10%, 9%, 2% and 9% respectively in the study group compared to 15%, 10%, 0% and 5% in the control group; the differences were statistically not significant. Cryptosporidium oocysts were not detected in both groups.

Very low estrogen-desogestrel contraceptive in perimenopausal hormonal replacement

New oral contraceptives (OC) with lower estrogen contents are potentially useful for menopausal replacement. An OC with 20 micrograms ethinyl estradiol and 150 micrograms desogestrel was used for this purpose in perimenopausal women with climacteric syndrome. The treated group (N = 30), was given OC for 6 months. The control group (N = 29) was kept under observation. Serum FSH, luteinizing hormone, estradiol, cholesterol, HDL-cholesterol and triglycerides were measured. OC treatment induced prompt and clear relief of the climacteric syndrome. Endogenous serum estradiol was greatly reduced with treatment. Serum cholesterol, initially high in relation to young women, diminished with OC treatment, while HDL-cholesterol increased, significantly reducing the cholesterol/HDL-cholesterol ratio. This possibly beneficial estrogen effect was apparently not counteracted by desogestrel (a nearly non-androgenic progestogen). The initially high triglycerides were not modified by the OC. Cyclical bleeding was induced in all treated women, no atypical endometrial hyperplasia was found. This lower estrogen OC preparation may be a good alternative for estrogen replacement in perimenopausal women; its contraceptive properties may strongly appeal those needing fertility control.

The presence of mast cells in the human endometrium pre- and post-insertion of intrauterine devices

A study of the density of mast cells in the human endometrium was carried out on biopsy specimens prepared for light microscopy in 87 cases with three types of IUDs (stainless steel ring SS-type, copper Cu-T 220 and LNG-IUD levonorgestrel-releasing device) pre- and post-insertion. The results revealed that, in general, there was an increase of mast cells after 3 to 24 months' use of IUD, independent of type (p < 0.01 when compared with the pre-insertion value). The increase in number of mast cells was most prominent in women having used the Cu-T220 IUD for 24 months (p < 0.05 when compared with the SS-IUD and p < 0.01 when compared with the LNG-IUD). The difference between the SS-IUD and the LNG-IUD as to the number of mast cells was not significant. No significant difference was found between the "bleeders" and "non-bleeders" in any of the three types of IUDs. It is noteworthy that patients using the Cu-T220-IUD had the highest percentage of patients with abnormal bleeding (> 50%) and that this group also had the highest density of mast cells per mm2 after 24 months' use. Although no significant difference with regard to the density of mast cells could be found between the "bleeders" and the "non-bleeders" in the present study, the number of "bleeders" of the three study groups is usually small and sometimes this number does not allow an adequate statistical analysis for comparison. Further investigations, involving larger number of IUD users, may yield a better understanding with regard to the potential relationship between the number of bleeding episodes and the density of mast cells in the human endometrium.

Emotional distress in Israeli women before and after abortion

Emotional distress in a group of Israeli women who requested legal abortion was compared with that in a group of women on the verge of delivery and in a random group of nonpregnant women on measures of anxiety and depression. Emotional consequences of the abortion were evaluated by before-and-after comparisons of the same measures in a subgroup of the aborting women. Findings indicated significantly greater distress in the aborting women, with lower levels after the abortion. The effects on emotional well-being of personal and contextual factors and their interactions were also examined.

Behavioural mechanisms in AIDS patients under stress

Clinical observation at the Kenyatta National Hospital showed unusually rapid deterioration of patients testing seropositive to HIV infection and being moved to a side room for nursing. This pilot study tested the hypothesis that deterioration was at least partly, mediated by B-endorphins and other endogeneous opioids. The study design was a prospective and comparative study looking at 6 HIV seropositive and 10 control (HIV seronegative) patients matched for sex, age, and clinical status at time of study. The laboratory measures compaired were baseline, and daily serum B-endorphin and ACTH. A significant variation is noted between the two groups. The significance of this study is discussed.

Differences in the low density lipoprotein subfraction profile between oral contraceptive users and controls

To investigate the effect of low dose oral contraceptives on the low density lipoprotein (LDL) subfraction profile, the distribution of the LDL subfraction patterns in 20 premenopausal women on oral contraceptive (OC) therapy and 41 premenopausal women not taking gonadal hormones was studied. The LDL subfraction patterns were identified by density gradient ultracentrifugation and each individual LDL subfraction pattern was characterized by the relative contribution of three major LDL subfractions: light, LDL1; intermediate, LDL2; and dense, LDL3 to total LDL. Serum lipid and lipoprotein levels were similar in OC users and controls, except for significantly higher triglyceride levels in OC users. As for the LDL subfraction patterns, among the OC users the mean relative contribution of dense LDL3 to total LDL was significantly higher than in the controls (32% +/- 8% vs. 26% +/- 13%, P < 0.05), whereas the relative contribution of light LDL1 to total LDL was significantly lower (27% +/- 8% vs. 34% +/- 10%, P < 0.01), indicating a higher prevalence of the more dense LDL subfraction patterns among OC users. Furthermore, the distribution of the LDL subfraction patterns in OC users (27% LDL1, 41% LDL2, and 32% LDL3) resembled that of men (25% LDL1, 43% LDL2, and 33% LDL3, n = 59). Statistical analysis revealed that OC use was significantly associated with a more dense LDL subfraction pattern, characterized by an increased relative contribution of LDL3 (+6%, P < 0.05) and a decreased relative contribution of LDL1 (-6%, P < 0.01), even after correcting for the influence of lipid and lipoprotein levels, which in controls were shown to have a significant relation to LDL3 and LDL1, respectively. So, independent of the lipid and lipoprotein levels, low dose OC alter the composition of LDL to a heavy, dense LDL subfraction profile, which reportedly has been associated with an increased risk of atherosclerosis.

Hygiene behaviour and hospitalized severe childhood diarrhoea: a case-control study

The relationship between personal and domestic hygiene behaviour and hospitalized childhood diarrhoea was examined in a case-control study of 356 cases and 357 controls from low-income families in metropolitan Manila. Indices of hygiene behaviour were defined for overall cleanliness, kitchen hygiene, and living conditions. Only the indices for overall cleanliness and kitchen hygiene were significantly associated with diarrhoea. An increasing excess risk of hospitalization with severe diarrhoea was noted as the ratings for standards of hygiene became lower, and this excess risk persisted even after controlling for confounding variables. The implications of our findings for the control of diarrhoeal disease are discussed.

The Butajira project in Ethiopia: a nested case-referent study of under-five mortality and its public health determinants

During one year of follow-up, 306 deaths of children under the age of 5 years were included in a concurrent case-referent study that was based on a population estimated at 28,780 in 1987. A total of 612 live referents, matched for age, sex and study area, were also selected from the study population through density sampling. Data were collected by lay reporters by verbal autopsy. For the study period the estimated cumulative under-five mortality rate was 293 and the infant (0-11 months old) mortality rate was 136 per 1000. Major probable causes of death were diarrhoeal disease or acute respiratory infections (ARI). The relative importance of parental and environmental characteristics was assessed using conditional multiple logistic regression analysis. Under-five mortality was associated with paternal illiteracy, maternal ethnicity, and not being in the committee of people's organizations. Parental factors affected the infants relatively more than they did the children, especially with regard to ARI mortality. This was also noted with "absence of window", a proxy measure for evaluating the type of housing. In terms of etiological fractions a greater number of under-five deaths could be ascribed to parental than environmental conditions, with relatively more infants being affected than children.

Determinants of sexual habits in Italian females

OBJECTIVE

To identify characteristics of women reporting multiple sexual partners and early age at first intercourse in Italy.

METHOD

Information on 1139 control women (median age 54 years) interviewed as part of a case-control study of cervical neoplasia conducted in the greater Milan area, Northern Italy were analysed using stratified analysis and multiple logistic regression.

RESULTS

Overall, 81% of the study sample reported no more than one sexual partner, 10% two and 9% three or more. The proportion reporting multiple sexual partners tended to be higher among younger and more educated women (4% vs 19% of women with respectively less than 7 and 12 or more years of education reported three or more partners). Ever smokers reported a higher number of sexual partners than never smokers. The proportion of nulliparae reporting three or more sexual partners was higher than that of parous women. These findings were confirmed after taking into account in a multivariate analysis the role of potential confounding factors. Furthermore similar findings emerged from an analysis restricted to women aged 40 years or less. Always considering number of sexual partners, no relationship emerged with marital status, spontaneous or induced abortions, lifetime number of reported Pap smears and contraceptive habits. With reference to age at first intercourse, 25% of the study population reported their first intercourse at age 18 or before, 34% between 19 and 22 years, and 41% at age 23 or later. Younger women (that is, more recent cohorts) more frequently reported earlier age at first intercourse and the proportion of never married women reporting early intercourse was higher (51% vs 22% of never married vs married women). No relationship emerged between education, smoking habits, parity, history of spontaneous or induced abortions, number of Pap smears, contraceptive habits, and age at first intercourse.

CONCLUSION

This study documents conservative sexual habits in Northern Italian females (at least on the basis of self reporting) but indicates that any educational compaigns towards safe sex should be focused towards younger women, particularly smokers, unmarried and nulliparae.

Protective efficacy of a serogroup B meningococcal vaccine in Sao Paulo, Brazil

Serogroup B Neisseria meningitidis is the most common cause of epidemic meningococcal disease in developed countries. Until recently no vaccine has been available for prevention of infection with this organism. In an attempt to control epidemic serogroup B meningococcal disease in greater Sao Paulo, Brazil, during 1989 and 1990, a Cuban-produced outer-membrane-protein-based serogroup B meningococcal vaccine was given to about 2.4 million children aged from 3 months to 6 years. We have done a case-control study to estimate the efficacy of the vaccine in greater Sao Paulo. Microbiologically confirmed cases of serogroup B meningococcal disease were identified through hospital-based surveillance. Controls were matched by neighbourhood and age. Vaccination status was confirmed by inspection of vaccination cards. Between June, 1990, and June, 1991, 112 patients and 409 matched controls with confirmed vaccine status were enrolled. Estimated vaccine efficacy varied by age: 48 months or older = 74% (95% Cl 16 to 92%), 24 to 47 months = 47% (-72 to 84%), and less than 24 months = -37% (< -100 to 73%). Our results suggest that the Cuban-produced vaccine may be effective for prevention of serogroup B meningococcal disease in older children and adults.

Maternal height and age: risk factors for cephalopelvic disproportion in Zimbabwe

Maternal age and stature are among several factors used to screen pregnant women for potential risk of labour complications. In a population-based case-control study in Harare, Zimbabwe, multivariate analysis was carried out to evaluate the importance of maternal age and height as risk factors for cephalopelvic disproportion (CPD). Using data abstracted from the medical records of 203 women with operative deliveries due to CPD and 299 women with normal unassisted vaginal deliveries, multiple logistic regression models were developed. Although maternal age < 18 years was not a significant risk factor in this study (perhaps because there were few women in this age group), advanced maternal age (> or = 35 years) was associated with a relative risk of 2.7 compared to women 20-34, after adjusting for other demographic and obstetric factors. Maternal height < 160 cm was associated with a twofold increased risk of CPD as compared to taller women.

Pregnancy loss and thrombosis with protein C deficiency

OBJECTIVES

Protein C inhibits coagulation and promotes fibrinolysis. This study investigates the association between protein C deficiency and pregnancy loss, thrombosis in pregnancy, and thrombosis with oral contraception.

STUDY DESIGN

Fifteen protein C--deficient patients and 37 controls from a single kindred were studied. An obstetric history was obtained by telephone. Data were analyzed by logistic regression, Fisher's exact test, and Student t test.

RESULTS

Protein C--deficient women experienced a 33% pregnancy loss versus 19% in the controls (not significant). Thromboembolism during pregnancy in protein C--deficient women was 33% (45% in those not receiving prophylactic anticoagulation) versus 5% in controls (odds ratio 7.37, p = 0.026). Five of 12 protein C--deficient women using oral contraception developed thrombosis versus 0 of 33 controls. The risk of thrombosis for protein C--deficient women using oral contraception is increased (p < 0.001).

CONCLUSIONS

Perinatal outcome is not statistically different with protein C deficiency. Protein C deficiency increases the risk of thrombosis during pregnancy and with oral contraception. Prophylactic heparin is suggested during pregnancy for protein C--deficient women with personal or family histories of thrombosis. Oral contraception is not advised.

Association between glucose-6-phosphate dehydrogenase deficiency and neonatal jaundice: interaction with multiple risk factors

This nonconcurrent cohort study was carried out to evaluate the association of neonatal jaundice with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency and its interactions with other risk factors. The G-6-PD enzyme activity of 12,379 neonates was screened by a semi-quantitative fluorometric assay and double-checked by a quantitative method to identify a G-6-PD deficient cohort of 333 neonates. Matched with these on birth date, sex and delivery hospital were a G-6-PD normal cohort of 653 neonates. Neonatal jaundice was defined by a peak serum bilirubin (PSB) level of > or = 15 mg/dl. A significant association between G-6-PD deficiency and neonatal jaundice was observed in male but not female neonates. There was an inverse dose-response relation between G-6-PD activity and neonatal jaundice among male neonates. Both hypoxia/asphyxia and maternal hepatitis B surface antigen (HBsAg) carrier status were associated with an increased risk of neonatal jaundice among G-6-PD deficient but not G-6-PD normal male neonates. Based on multiple regression analyses, an additively synergistic effect on PSB level and severe jaundice (PSB > or = 20 mg/dl) was observed for G-6-PD deficiency and maternal HBsAg carrier status.

A randomized, double-blind, placebo-controlled comparison of the impact of low-dose and triphasic oral contraceptives on follicular development

OBJECTIVE

This investigation tests the hypothesis that triphasic oral contraceptives are associated with the development of large, persistent ovarian cysts.

STUDY DESIGN

Weekly vaginal ultrasonography was used in a randomized, double-blind, placebo-controlled, parallel-group, single-center study that compared the incidence, risk, size, and time to resolution of ovarian follicles in healthy women who took Estrostep or Loestrin oral contraceptives (manufactured by Parke-Davis) or a placebo during three consecutive menstrual cycles.

RESULTS

Sixty-three percent of placebo-treated subjects developed follicles greater than 18 mm, compared with 39% and 23% in the Estrostep and Loestrin groups. The risks for each group of developing a large follicle during a single cycle were not different. No dominant follicle persisted for greater than 2 weeks for any subject.

CONCLUSION

These results demonstrate that follicular development continues during treatment with oral contraceptives. In addition, the findings fail to support the hypothesis that triphasic oral contraceptives result in persistent ovarian cysts.

Genital tract infections associated with the intrauterine contraceptive device can be reduced by inserting the threads into the uterine cavity

OBJECTIVE

To study the influence of the position of the threads of an intrauterine contraceptive device (IUCD) on the development of genital tract infection.

DESIGN

A multicentre randomized controlled trial.

SUBJECTS

Women requesting an IUCD.

INTERVENTIONS

The women were randomized to be fitted with an IUCD either with the threads contained in the uterine cavity (threads-up group) (n = 208) or passing through the cervix to the vagina in the usual way (threads-down group) (n = 237). Multiple centre study with follow-up at three months, 1 and 2 years. At the final visit 'missing' threads were retrieved using a disposable instrument (Retrievette).

MAIN OUTCOME MEASURES

The occurrence of infection in the lower or upper genital tract.

RESULTS

63 women in the threads-up group and 78 in the threads-down groups dropped out. Previous gynaecological infection was reported by 21 and 48 women in the threads-up and threads-down group, respectively (odds ratio 0.44, 95% CI 0.24 to 0.79), 21 and 53 subjects had signs of infection at gynaecological examination (odds ratio 0.39, 95% CI 0.21 to 0.69) and a wet-smear was pathological in 33 and 79 (odds ratio 0.38, 95% CI 0.23 to 0.61). In the threads-up group the vaginal pH was also lower at the final check up after 2 years. Spontaneous descent of the threads occurred in 11% of the threads-up group and in six women in the threads-down group the threads were in the cervix. In 93 women the threads were easily retrieved by means of the Retrievette, four women insisted on the threads remaining in the uterus and in 18 thread removal was performed under local or general anaesthesia.

CONCLUSIONS

Infectious complications in women using an IUCD are more frequent if the threads lead from the uterine cavity to the vagina. This problem can be reduced by inserting the threads so that they remain entirely within the uterine cavity, a feasible procedure now that an effective instrument for IUCD thread retrieval is available.

Early changes of affinity and binding sites of progesterone and oestrogen receptors in decidua exposed to RU 486

Sixty patients with 6-7 weeks of amenorrhoea were randomly allocated to three groups. The women in the first group (control) took a placebo 24 h before undergoing a vacuum aspiration. The patients in the second and third groups were given 200 mg of RU 486 orally, 12 or 24 h before surgical interruption of their pregnancy. Decidua were collected and frozen in liquid nitrogen. By Scatchard plot analysis, the number of cytosolic binding sites (1798 +/- 803 fmol/mg DNA) of progesterone in decidua in the control group was significantly reduced (P less than 0.01) to 696 +/- 408 or 626 +/- 179 fmol/mg DNA by RU 486 treatment for 12 or 24 h respectively. The dissociation constants of both cytosolic and nuclear progesterone receptors in RU 486-exposed decidua were increased (P less than 0.01). The number of nuclear binding sites of oestrogen receptor was significantly higher (P less than 0.05) in decidua with RU 486 treatment for 12 h (178 +/- 77 fmol/mg DNA) compared to the control (89 +/- 32 fmol/mg DNA). The results suggest that RU 486 might regulate progesterone and oestrogen receptors in the decidua of early human pregnancy, either directly or indirectly.
