Ectopic pregnancy in African developing countries.

OBJECTIVE: We have reviewed the scientific literature on ectopic pregnancy (EP) in African countries published over the past 20 years and available from several databases (MEDLINE, EMBASE, POPLINE, and Cochrane Fertility Regulation Group), with the aim of painting a complete picture of the situation (incidence, risk factors, diagnosis, treatment, and complications). RESULTS: Although hospital-based African studies indicate EP incidence has probably increased in Africa in recent decades, major methodological limitations in the published literature make it impossible to draw formal conclusions concerning the incidence of EP in Africa in recent years. As in industrialized countries, pelvic inflammatory disease (PID) associated with sexually transmitted diseases (STDs) must be considered as the most important risk factor for EP in developing countries. In African developing countries, a majority of hospital-based studies have reported EP case fatality rates of around 1-3%, 10 times higher than that reported in industrialized countries. Late diagnosis, leading in almost all cases to major complications, and emergency surgical treatments are key elements accounting for such high fatality rates in women suffering from EP in Africa. CONCLUSION: EP should be considered a relevant public health indicator in developing countries, providing an overall picture of the capacity of a health system to deal with the diagnosis and treatment of emergency situations, especially in the field of obstetrics and gynecology.

Increasing incidence of testicular cancer worldwide: a review.

PURPOSE: Testicular cancer (TC) is the most common malignancy in 20 to 34-year-old men. Numerous publications have shown an increase in the incidence of testis cancer in the last 40 years with substantial differences among countries. We evaluated worldwide variations in testicular cancer incidence and compared trends in different regions in the world. MATERIALS AND METHODS: We reviewed 441 studies provided by a MEDLINE search using the key words testis/testicular, cancer/tumor and incidence that were published between 1980 and 2002. From these articles we selected only those devoted to testis cancer incidence and of them only the most recent studies from each country or region. Nevertheless, articles using the same data base but providing new and additional information, for example differences among ethnic groups or controversial explanations for trends, were also retained. We selected 30 articles and analyzed their methodological approach and main results. RESULTS: Worldwide we observed a clear trend toward an increased TC incidence in the last 30 years in the majority of industrialized countries in North America, Europe and Oceania. Nevertheless, surprising differences in incidence rates were seen between neighboring countries (Finland 2.5/100,000 cases versus Denmark 9.2/100,000) as well as among regions of the same country (2.8 to 7.9/100,000 according to various regional French registers). In addition, substantial differences in the TC incidence and trends were observed among ethnic groups. The increase in the TC incidence was significantly associated with a birth cohort effect in the United States and in European countries. To date except for cryptorchidism no evident TC risk factor has been clearly demonstrated, although the environmental hypothesis with a key role of endocrine disrupters has been put forward by several groups. CONCLUSIONS: Such a recent increase in the TC rate in most industrialized countries should lead urologists and andrologists to give more attention to testicular cancer symptoms in adolescents and young adults. In a public health perspective further research using cases collected through national and regional population based registers and case-control studies must be strongly encouraged if we wish to be able to assess future trends in TC incidence rates and also identify risk factors.

Prevalence of erectile dysfunction in France: results of an epidemiological survey of a representative sample of 1004 men.

OBJECTIVE: Several recent studies have reported prevalence rates for erectile dysfunction (ED) displaying considerable variation from country to country. We report here the results of a survey carried out in France in 2001. METHODS: This study was carried out by means of telephone interviews, on a representative sample of 1004 men aged 40 years or over. The prevalence of ED was determined from the patient's self-evaluation and International Index of Erectile Dysfunction 5 (IIEF-5) score. RESULTS: We found that in France in men aged 40 years and over, one man in three (31.6%) presented ED, of essentially mild or moderate severity (according to IIEF-5 score). We also found that the majority of men suffering from ED expressed dissatisfaction with their relations with their partner. Finally, a large proportion of men stated that they were ready to consult a doctor. CONCLUSION: This survey confirms that the prevalence of ED is high in France. This condition, which represents a source of distress that remains difficult to express and to assess, should be evaluated more effectively by rigorous and standardised methods, particularly as oral and effective treatments are now available.

Paternal age and maternal age are risk factors for miscarriage; results of a multicentre European study.

BACKGROUND: It is well known that miscarriage risk increases with age. However, studies usually investigate only maternal age effects. We investigated both maternal age and paternal age effects on miscarriage risk to provide insight into this frequent reproductive failure. METHODS: The last planned pregnancies (n = 3174) that ended in a birth or miscarriage were analysed in a retrospective population-based study on women aged 25-44 years in Denmark, Germany, Italy and Spain. Maternal and paternal ages were analysed together, using a single variable 'couple age' in a multivariate logistic regression analysis, with couples composed of a woman and a man both aged 20-29 years forming the reference group. RESULTS: After adjustment for various factors (e.g. reproductive history, country), we found that the risk of miscarriage was higher if the woman was aged > or = 35 years, as has already been reported in a number of studies. However, the increase in risk was much greater for couples composed of a woman aged > or = 35 years and of a man aged > or = 40 years. Potential source of bias (especially 'reproductive compensation') are discussed. CONCLUSIONS: The risk of an adverse pregnancy outcome is highest if both partners are advanced in age.

Ectopic pregnancy in Conakry, Guinea.

OBJECTIVE: To assess the incidence of ectopic pregnancy (EP) in hospitals in Conakry, the capital of Guinea, West Africa. Data on EP incidence in developing countries are rare and often out of date, particularly in Africa. METHODS: A retrospective study was carried out, examining all cases of EP registered in the medical files of two referral maternity units at the Donka and Ignace Deen university hospitals between 1995 and 1999. FINDINGS: The EP incidence at the two maternity units increased from 0.41% to 1.5% of annual deliveries over this period. Haemoperitoneum was observed in most women, with tubal rupture in 93%; only 6 women received conservative treatment. CONCLUSION: The results suggest that the hospital-based incidence of EP per delivery has increased over the last decade in this West African capital, and that health professionals and public health officials in developing countries, especially those in Africa, should consider EP as a major obstetric problem for maternal morbidity.

[Prevalence of erectile dysfunction in France: results of an epidemiological survey conducted on a representative sample of 1004 men].

OBJECTIVE: Several studies have recently reported the prevalence rates of erectile dysfunction (ED) that vary according to the country. The authors report the results of a survey conducted in France in 2001. MATERIAL AND METHODS: This study was conducted by telephone conversation with a representative sample of 1,004 men over the age of 40. The prevalence of ED was measured by the patient's self-assessment and by the IIEF-5 index. RESULTS: The results show that about 1 man in 3 (31.6%) suffers from ED in France, which is essentially mild to moderate (according to IIEF-5). The majority of men reporting ED declared to be dissatisfied with their relationship with their partner. Finally, a large proportion of men declared that they would be willing to consult a practitioner. CONCLUSION: This survey confirms the high prevalence of erectile dysfunction in France. It is responsible for a distress that is still difficult to express and assess. This disease needs to be more accurately evaluated by rigorous and standardized methods, especially as simple and effective treatments are now available.
