Effect of intra-epididymal injection of copper particles on fertility, spermatogenesis, and tissue copper levels in rats.

In male rats, a single injection of 10 mg metallic copper particles in oil into each caput epididymidis induced infertility, whilst leaving mating behaviour and blood testosterone levels unchanged. Fertility tended to recover 5.5 months after the copper treatment. Although the copper content of the caput epididymidis reached a level of around 100 times higher than control values, the serum copper concentration did not rise significantly. This finding and the observation that treated animals gained weight as fast as the controls suggest a low systemic toxicity of this method. The testicular copper concentration was significantly higher than that in controls and different degrees of damage, including vacuolation, karyorrhexis, pyknosis, and cytolysis, were seen mainly in pachytene spermatocytes and early spermatids. Clumps of foreign particles, apparently metallic copper, were found in the interstices of the caput epididymidis together with degenerative changes in the epithelial cells of the caput, suggesting a possible effect of copper on the epididymal epithelium. The viability of epididymal sperm decreased more markedly than the decrease in sperm density. It is therefore most likely that the major cause of infertility after copper injection into the caput epididymidis is a direct inhibitory effect of copper on the sperm, whilst damage to the seminiferous and epididymal epithelial may contribute.

A tale of 2 cities: a comparison of demographic details, source of referral, spectrum of infection and contraceptive practice in patients under 16 years attending genitourinary medicine clinics in London and Swansea.

Sexually transmitted infections (STIs) in young people are increasing, with children aged less than 16 years being particularly vulnerable. We compared the demographic details, spectrum of infection, contraceptive practice and source of referral in patients aged less than 16 years attending 2 genitourinary clinics, one in Swansea and the other in London. In the London population, children aged less than 16 years represented 0.7% of the total new attendances compared with 1.4% in Swansea. The female to male ratio was almost 4:1 in both clinics with most infections confined to female attenders. In females the incidence of chlamydial infection, genital warts and anaerobic (bacterial) vaginosis was 5.5%, 19% and 8%, respectively in London compared with 27%, 32% and 36% in Swansea. Seventy-two per cent of patients attending the clinic in London were self referred compared with 40% in Swansea. Contraceptive practice was also markedly different in the 2 populations, and over one-third of children in both clinics used no contraception. The high incidence of STIs in both populations and low use of contraception has serious implications for the sexual health of young people and emphasizes the need for effective sexual health education at an early age.

Women's health care in Operation Iraqi Freedom: a survey of camps with echelon I or II facilities.

OBJECTIVE: To assess women's perceptions of health care delivery in Operation Iraqi Freedom. METHODS: An anonymous questionnaire was distributed through command channels to female soldiers stationed in camps receiving echelon I or II care. Questions covered predeployment screening, contraceptive method availability and side effects, accessibility of gynecologic care, field hygiene counseling, and smoking status. RESULTS: Two hundred fifty-one (91%) of 275 surveys were returned. Twenty-two percent of respondents had received no annual gynecologic examination including the Papanicolaou test/cervical cytologic study in the past year. Irregular bleeding was the most common gynecologic side effect. Ortho Evra patches fell off in 58% of cases; 23% of soldiers changed contraceptive methods because of unavailability, 21% experienced gynecologic problems, and 44% could not access gynecologic care. Twenty-six percent received predeployment menstrual hygiene counseling, and 77% attempting cycle control succeeded. CONCLUSIONS: Gynecologic screening, contraceptive options, and cycle control counseling must occur before deployments. Specialty gynecologic care and medications for cycle control should be readily accessible to all female soldiers during deployments.

Female tumours in Italy: an example of quantitative assessment of disease burden and preventive strategies.

Female tumours (ie cancers of the female genital tract and breast) represent alone about 40% of new cases and 30% of cancer deaths in Italy (approximately 44,500 new cancer diagnoses and 17,800 deaths in 1991). An attempt to identify major issues in the primary and secondary prevention of these malignancies has disclosed several important points. Firstly, concerning epidemiology, excesses of mortality from cancers of the breast and ovaries exist in the northern part of Italy as compared to the centre and south, whereas mortality rates from uterine cancer are almost equally distributed. However, a tendency towards increasing similarity of various Italian regions emerges. Risk factors most amenable to intervention are overweight, contraceptive methods and dietary habits. Secondly, concerning screening, the number of mammograms (about 552) and the number of Pap smears taken every year (about 4 million) are approximately sufficient to provide a complete coverage of the target subset of the female population as concerns breast and cervical cancer screening. Still, on account of no one carrying out primary call procedures and checks, the actual situation is unsatisfactory. The present article, in addition to quantifying the present status of female cancer prevention in Italy, tries to define a framework for similar exercises in other European countries.

Human papillomavirus infection among women attending health facilities in the Kingdom of Bahrain.

OBJECTIVE: To investigate the occurrence of human papillomavirus (HPV) infection and the associated risk factors in Bahrain's female population. METHODS: This study was carried out between March to December 2004, which includes cervical scrapings for Pap smear and HPV-DNA testing using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis, obtained from 100 women attending the Gynecology Clinic at Salmaniya Medical Center and Sheikh Sabah Health Center in the Kingdom of Bahrain. We distributed questionnaires that include the sociodemographic data as well as information on risk factors such as smoking, parity, and the contraceptive used. RESULTS: Eleven women (11%) with normal cytology were HPV-positive. The RFLP analysis detected HPV-types 16, 18, 45, 62 and 53. Positive women were significantly older (43.3 +/- 10.1 years) than negatives (36.5 +/- 9.9 years; p=0.04), however, there was no difference in age of first sexual contact (positive: 18.1 +/- 5.7 years versus negative: 20.6 +/- 4.4 years). Polygamy, smoking and hormonal contraception was not identified as risk factors, but positive women showed higher parity. CONCLUSION: In this study on HPV infection in Bahrain, the 11% positivity with high risk HPV types, in the presence of normal cytology suggests that in addition to the cervical cancer screening program, offer of HPV testing deserves consideration.

Barriers to prescribing the Copper T 380A intrauterine device by physicians.

From a questionnaire sent to all obstetricians and gynecologists and all family and general practitioners in San Diego County, California, regarding the Copper T 380A intrauterine device, substantial barriers to prescribing it were identified. Of all physicians responding, 40% reported that they were not recommending the Copper T 380A to anyone, the single most common reason given being concern about medical liability. A lack of knowledge about the new device, a lack of intrauterine device insertion skills, and certain medical practice settings were also important barriers to prescribing it. The new intrauterine device is considered in the context of innovation-diffusion theory. Substantial amounts of education and training and improvement in the medical-legal climate are needed before current barriers to prescribing the new device are removed.

A direct mailing to teenage males about condom use: its impact on knowledge, attitudes and sexual behavior.

In August 1987, a letter, informational pamphlet and order coupon for free mail-order condoms were sent to an experimental group of teenage males 16-17 years of age. An experimental design was used to measure the impact of the mailing on teenagers' knowledge, attitudes and behavior. Approximately five weeks after the mailing, 985 members of this group and 1,033 members of the control group (who received no mailing) were interviewed by telephone. About seven months after the mailing, members of the experimental group who claimed they had ordered the free condoms were reinterviewed by phone. The results of the initial interviews revealed that about three-fourths of the teenagers in the experimental group had received the materials, and about two-thirds had read them. Moreover, males in the experimental group, particularly those who reported having received and read the pamphlet, were slightly but statistically significantly more knowledgeable about sexually transmitted diseases (STDs), pregnancy and contraceptives. On the other hand, there were no differences between males in the experimental and control groups in attitudes toward STDs or birth control, nor were there differences in actual sexual activity or in the use of birth control. However, the experimental group was significantly more likely to have ordered condoms by mail, presumably as a result of having received the free mail-order condom offer. Many of those who ordered condoms had previously had sex and had used condoms. However, a sizeable portion of those who ordered condoms did so prior to first intercourse, suggesting a possibly important early intervention.

Characteristics of ovulation method acceptors: a cross-cultural assessment.

Five programs of instruction in the ovulation method (OM) in diverse geographic and cultural settings are described, and characteristics of approximately 200 consecutive OM acceptors in each program are examined. Major findings include: the religious background and family size of acceptors are variable, as is the level of previous contraceptive use. Acceptors are drawn from a wide range of socioeconomic and religious backgrounds; however, family planning intention was similarly distributed in all five countries. In sum, the ovulation method is accepted by persons from a variety of backgrounds within and between cultural setting.

Peliosis hepatis associated with cavernous hemangioma and hepatocarcinoma.

Peliosis hepatis is a rare lesion characterized by blood-filled cavities randomly distributed in the liver. It has been associated with the administration of medications such androgen-anabolic steroids, estrogens, oral contraceptives, and azathioprine. Its diagnosis is most reliably obtained by arteriogram and liver biopsy. Treatment consists of the discontinuance of those medications known to induce liver changes. Surgical treatment is reserved for those cases where a concomitant neoplasm or aneurysm is found.

Reproduction-related risk factors for mucinous and nonmucinous epithelial ovarian cancer.

The proposition that mucinous ovarian cancer has an etiology distinct from that of other histologic types has been evaluated using data from a population-based case-control study of epithelial ovarian cancer conducted in 1990--1993 among Australian women aged 18--79 years. The protective effects of parity and oral contraceptive use were greater in nonmucinous than in mucinous ovarian tumors. However, these differences appeared to be driven largely by the effect of ovulatory life, which was positively associated with nonmucinous tumors only. An association with family history of breast and/or ovarian cancer also appeared to be restricted to nonmucinous cancers. These results lend support to the hypothesis that mucinous and nonmucinous ovarian tumors develop via different causal mechanisms.

Trends in serum lipid levels during 1980-1992 in children and young adults. The Cardiovascular Risk in Young Finns Study.

To assess secular trends in serum lipid levels in Finnish children and young adults, the authors examined a total of 3,517, 2,769, 2,392, 352, and 880 subjects who had complete data on serum lipids in 1980, 1983, 1986, 1989, and 1992, respectively, in a longitudinal follow-up study. Trend analyses were carried out among subjects aged 15 (n = 1,835) or 18 (n = 1,562) years to exclude the confounding effect of age on the study variables. Data on obesity, physical activity, smoking, and alcohol use were available from each study year, and data on diet were available for the study years 1980, 1986, and 1992. Between 1980 and 1992, mean total cholesterol levels decreased from 4.88 to 4.47 mmol/liter (from 189 to 173 mg/dl), and low density lipoprotein cholesterol levels decreased from 3.06 to 2.85 mmol/liter (from 119 to 110 mg/dl). The mean high density lipoprotein cholesterol levels decreased by 19%, from 1.43 to 1.15 mmol/liter (55.2 to 44.6 mg/dl). During 1986-1992, triglyceride levels increased by 15%, from 0.88 to 1.01 mmol/liter (78.2 to 89.9 mg/dl). During 1980-1992, body mass index values increased from 20.8 to 21.8 kg/m2, parallel to increases in skinfold thickness. In the diet, the ratio of polyunsaturated to saturated fatty acids increased from 0.26 to 0.39. Alcohol and oral contraceptive use became more frequent, and the subjects tended to become less physically active. In conclusion, a change in the lipid profile in Finnish adolescents aged 15 and 18 years and young adults during 1980-1992 was observed, characterized by a decrease in low density lipoprotein cholesterol and high density lipoprotein cholesterol levels and an increase in triglyceride level. Possible determinants for these changes include alterations in diet and a trend toward increased obesity.
