[Weight gain and progestin-only contraceptives: more concern than evidence]. / Prise de poids et contraceptifs à progestatifs seuls: plus d'inquiétude que de preuves scientifiques.

Weight gain is a side effect often associated with progestin-only contraceptives. A recently published Cochrane review focuses on this issue that has been addressed in only few studies of good quality. Here we discuss the results of this review in the context of three clinical cases. With progestin-only contraceptives the weight gain is less than often thought, especially after six or twelve months of treatment. Some results are rather reassuring, especially those in obese women and during the post-partum period. This should help improve the compliance of women who fear gaining weight with this type of hormonal contraception.

[Menstrual disorders in adolescents: commonplace or worrisome?]. / Troubles du cycle à l'adolescence: une banalité?

The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.

[Role of the PAP smear in adolescence]. / Place du frottis cytologique à l'adolescence.

The publication of the 2006 directives concerning the management of PAP smears has incited us to update our internal protocols at the CHUV, which are described in this article. A new addition to these directives is the specific management of adolescent PAP smears, who present both a high HPV carriage rate and increased incidence of cytological abnormalities with a favorable outcome in most cases. Our goal is to avoid over-treating dysplasias in this type of patient in order to avoid long-term complications. Emphasis is placed on the first gynecological consultation where a listening ear and clear and targeted information remain essential in the proper management of a young patient.

[Sexual abuse of female children and adolescents--detection, examination and primary care]. / Sexueller Missbrauch bei Kindern und Jugendlichen- Aufdeckung, Untersuchung und Erstbetreuung.

Epidemiological studies show a prevalence of sexual abuse experience among girls from 14-33%. Although indicators of abuse are unspecific, the combination of several findings may be indicative: Somatic signs may be sexually transmitted diseases, vulvovaginal complaints. Psychosocial nonsexual indicators are abrupt behavioural changes, running away from home, eating disorders. Psychosexual signs are hypersexualisation of the language and behaviour, disturbed body image and gender identity. Indirect evidence of abuse is given not only in cases of old vaginal and anal lesions but also in situations, where deep tears of the hymen in the typical localization at the posterior part can be found. The workup and care for children in whom there is suspicion of abuse but no clear evidence asks for highly competent professionals in a multidisciplinary cooperation including pediatric gynecologists, child psychiatrists, children-protection groups and other specialists to avoid on one hand unjustified destabilisation or even destruction of familial structures but to assure on the other hand, that the child victims are treated and followed after in a short and long term comprehensive medical and psychosocial care.

[Sexual and reproductive health--specific problems in adolescence]. / Santé reproductive--problèmes spécifiques à l'adolescence.

The specificity of adolescent gynecology is uncontested and asks for a specific knowledge and approach. Even if the symptoms remain the same, differential diagnostic and therapeutic approach will be different, depending on the state of development (early puberty, late adolescence), during which they occur. The ignorance of specific pathologies (utero-vaginal malformation, ovarian pathologies related to the menstrual cycle) and therefore inadequate or retarded medical treatment might be the source of unnecessary sequellae. There are now many possibilities to acquire or improve one's knowledge and skills in this particular domain of gynecology. The medico-legal situation as well differs in many points from that of the adult.

[How to improve use of emergency contraception by adolescents?]. / Comment améliorer l'utilisation de la contraception d'urgence par les adolescents?

OBJECTIVES: To give an overview of knowledge on emergency contraception (EC) and its utilization in the adolescent population, and to present the practical guidelines useful for EC prescription. METHODS: Review of the literature on EC and results of a survey on sexual behavior of 16-20-year-olds in Switzerland are used. RESULTS: Both estrogen-progestin and estrogen are used for EC. Condom breakage, lack of compliance in oral contraception and failure in contraceptive use are the main reasons for using EC. Sexually active adolescents are aware of CPC and 20% of girls have used it in Switzerland. However, insufficient information and low quality of services in emergency situation could be important barriers to the use of EC. DISCUSSION: and conclusion. Practical knowledge and information on EC must be disseminated among adolescents and both professional training and development of the quality of services have to provide better access to EC.

[Adolescent sexuality: epidemiology, clinical approach and preventive measures]. / Sexualité des adolescents: epidémiologie, approche clinique et stratégies préventives.

The interest in sexuality of adolescents in medical practice is often mainly focussed on the onset of sexual intercourse and on the emergence of contraceptive needs, though the beginning of adolescence takes place much earlier with the first signs of puberty followed by the menarche. At the issue of this profound metamorphosis the adolescent needs to adapt herself to a modified, sexual body. Adolescence is also a time of identity development and of changes in relationships, which are influenced by gender role in family and perception related to gender during childhood. This article shows epidemiological data to consider and the main issues of gynaecologic consultation with the adolescent. The different stages of development depend on biological and environmental factors which either favour resilience or weaken the individual due to a lack of affection or to abusive relationships. Medical consultation for a gynaecological problem, questions on puberty and development or on contraception give medical professionals and especially gynaecologists a chance to address sexual issues naturally, to anticipate questions as well as contraceptive needs. The consultation with the adolescent includes also the screening for behaviour related to a lack of information or a personal or relational difficulty.

A 3-year study of prevention of postmenopausal bone loss: conjugated equine estrogens plus medroxyprogesterone acetate versus tibolone.

The aim of this study was to investigate the effects of tibolone in the prevention of postmenopausal bone loss over 3 years, and to compare these with the effects of sequential hormone replacement therapy. Forty early postmenopausal women were randomized to a 21-day regimen of conjugated equine estrogens (CEE, Premarin) plus sequential medroxyprogesterone acetate (MPA, Prodafem), or tibolone (Livial) daily. In total, 36 women completed 12 months and were considered for the intent-to-treat analysis, 34 completed 24 months and 23 completed 36 months. Main drop-out reasons were: lost to follow-up (n = 9) and minor side-effects (n = 4). Bone mineral density was measured at baseline and after 6, 12, 24 and 36 months, using dual-energy X-ray absorptiometry at the lumbar spine and the upper femur (neck, trochanter, total hip). In both groups, bone loss was prevented. Treatment with tibolone demonstrated significant increases in bone density at the spine (+4.6%; p < 0.01), at the total hip (+3.2%; p < 0.01) and at the trochanter (+4.5%; p < 0.01), whereas the CEE/MPA group showed a non-significant increase of bone mineral density at the lumbar spine (+2.6%) but no increases at the hip. Between-group differences in bone mineral density changes were significant (p < 0.05) for the total hip and the trochanter at 36 months. This increase of bone mineral density was not accompanied by changes in insulin-like growth factor-I (IGF-I) or insulin-like growth factor binding protein-3 (IGFBP-3) in either group. Osteocalcin, alkaline phosphatase and urinary ratios of hydroxyproline/creatinine and calcium/creatinine significantly decreased in both groups. In conclusion, sequential CEE/MPA prevented cortical and trabecular bone loss, with a transient increase of bone mineral density only during the first 6 months. Tibolone not only prevented cortical and trabecular bone loss, but further increased bone mineral density at the lumbar spine and at the hip throughout the 3 years of treatment, suggesting a sustained positive effect on bone mass.
