Vaccination against the human papilloma virus (HPV) has been included in the national Vaccination Programme of the Netherlands for 12-year-old girls since 2010. Vaccination coverage for the birth cohort of 1997 was 56.; there is a gradual increase in uptake. Continuous safety monitoring brought no new unknown serious side effects to light; many girls suffered from transient symptoms such as painful arm, fatigue and headache. After the current vaccines that protect against HPV types 2 and 4 types, respectively and induce some cross protection, vaccines are being developed that can induce broader protection. HPV vaccination of 12-year-old girls is cost-effective, even for relatively low vaccination coverage. The potential protection of HPV vaccination extends beyond prevention of cervical cancer by preventing other oncological manifestations of HPV infection in women as well as men and genital warts. The preventive HPV vaccines do not appear to be effective in treating existing abnormalities.

In light of the 125th anniversary of the Dutch Society of Obstetrics and Gynaecology (NVOG), the Netherlands Journal of Medicine (NTvG) will publish a series of articles over the coming months. The articles will cover various topics from the specialty areas of gynaecology and obstetrics. We hope that these articles will inspire you, so that, in another 25 years, we can report again on positive developments of our specialty for patients, doctors and the community.

Autonomous pelvic nerves are essential for bladder and rectum function as well as sexuality. These nerves are usually permanent damaged during radical oncological surgery and this results in urological, sexual and proctological morbidity. Japanese surgeons have paved the way for surgical approaches to dissect these nerves during surgery and leave them intact. At the Department of Gynaecology of the Leiden University Medical Center, the Netherlands, a new surgical technique has been developed to spare the autonomous pelvic nerves during radical hysterectomy. In this procedure the lateral parts of the sacro-uterine ligament, through which the N. hypogastricus passes bilaterally, are left intact. The initial results of this nerve-sparing surgical technique during radical hysterectomy seem to be promising. The operation was easy to perform, with almost no extra blood loss and an extra operating time of just 10-15 minutes. Postoperative recovery of the bladder function occurred after a mean period of 9 days.

About 5% of all ovarian-cancer cases are caused by a genetic predisposition, in particular as a component of the autosomal dominant hereditary breast-ovarian-cancer syndrome. This syndrome is usually due to germline mutations in the BRCA1- or BRCA2-gene. Ovarian and endometrial cancer also occur in families with hereditary non-polyposis colorectal cancer (HNPCC). This syndrome is caused by germline mutations in DNA mismatch-repair genes. Women at high risk of gynaecological cancer based upon familial clustering of disease or a demonstrated pathogenic germ-line mutation are candidates for surveillance: annual gynaecological examinations, including vaginal echoscopy and serum carcinoma antigen CA125 testing. Prophylactic surgery in the form of adnexectomy leads to a marked, but not complete, reduction of ovarian-cancer risk in high-risk cases. There is insufficient evidence to advise against the use of oral contraceptives or hormonal substitution after adnexectomy for healthy women with a genetic predisposition to breast cancer. Recommendations for surveillance and prevention should only be given after genetic-risk counselling, based on a detailed family study and DNA-based diagnosis.

The Dutch College of General Practitioners' practice guideline 'Vaginal bleeding' is a useful instrument for general practitioners. The changes in the present version are based on recent developments in diagnostic and therapeutic possibilities, such as (hydro-)ultrasonography to diagnose intracavitary abnormalities, progesterone-containing 'intra-uterine devices' (IUDs) and endoscopic techniques for destroying the endometrium. The recommendation to prescribe cyclical progestogens in the case of hypermenorrhoea is not supported by randomised studies. On balance, this guideline provides clear and useful advice for the treatment of abnormal vaginal blood loss.

Objective: To analyse local tumour parameters of early cervical cancer that might be of prognostic significance for tumour relapse in the pelvis., Design: Retrospective., Method: Data were collected from 308 patients who underwent radical hysterectomy and pelvic lymphadenectomy in the years 1984-1996 in the Leiden University Medical Centre, the Netherlands. Treatment policies and operating staff were the same during the study period. The existence of relapse was studied by physical, gynaecological, laboratory and, if indicated, radiological examination., Results: Data on 294 patients were available for analysis. Their mean age was 45 years (range: 21-82). Postoperative radiation treatment was given to 119 patients (40%). Mean follow-up duration was 36 months (range: 1-136). Recurrences had developed in 46 patients (15.6%), 29 of whom had died. The calculated overall 5-year survival rate was 83%; 91% for those with negative and 53% for those with positive pelvic nodes. The calculated recurrence-free-5-year survival rate was 75% for the entire group, 83% for the patients without and 47% for those with lymph node metastases. When more than one lymph node region was affected, 5-year disease free survival was 19% and when lymph node metastasis occurred bilaterally, it was 22%. Multivariate analysis revealed that lymph node involvement (hazard ratio: 4.4), parametrial involvement (5.5), tumour size > 30 mm (4.6) and depth of invasion > 10 mm (5.1) were independent factors of prognostic significance for disease free survival. The current indications for adjuvant treatment might be extended with infiltration depth. The number and the bilaterality, if any, of affected lymph node stations might be indication for additional adjuvant therapy.

A 73-year-old woman with minor intellectual skills had complaints which suggested a vulvar carcinoma. Despite her refusal she was examined and admitted to hospital, on the basis of good professional care. The psychiatrist examined her and judged her incompetent. For the operation of the diagnosed vulvar carcinoma a court ordered representative was obtained. Two months later she underwent radiotherapy to prevent local complications and pain and a few weeks thereafter she died. Because medical decision-making in a doctor-patient relationship is not always possible decision-making power should be assigned to a third party. That forms the basis of proper medical care.

Objective: To determine the frequency of sexual difficulties and of sexual and physical abuse., Design: Descriptive survey study., Setting: Outpatient gynaecology clinic of the University Hospital of Leiden, the Netherlands., Patients and Method: During 3 months, December 1994-February 1995, all consecutive new female patients were questioned by the gynaecologist by means of a short standardised questionnaire. Oncology patients and non-Dutch-speaking patients were excluded. Data were analysed with descriptive statistical procedures; relationships among variables were tested with the chi 2 test with Yates' correction or Fisher's exact test., Results: Of 325 patients 34.2% reported sexual difficulties, 15.4% reported sexual abuse and 7.4% physical molestation. Age of the patient and presence or absence of the partner during the consultation were not associated with differences in the patients' reports. 18.8% of the patients with these complaints answered affirmatively when asked if they needed specialised help., Conclusion: Sexual difficulties and sexual and physical abuse were common among gynaecology patients. Less than one-fifth of them required specialised help.

One hundred consecutive radical hysterectomies performed in a Dutch oncology centre during a five and a half year period between 1984 and 1990, were analysed. The operations were performed in a uniform manner by the same three surgeons. Surgical mortality was nil. Mean operating time was 4 hours and mean blood loss amounted to 1200 ml. One patient developed a vesicovaginal fistula. Long lasting urinary symptoms occurred in 32% of patients, sex problems in 13%. The latter situation was encountered significantly more frequently when surgery was combined with radiotherapy. Eighty-two of the 100 patients had a primary cervical carcinoma and were analysed further. Distribution according to stage was as follows: stage IA: 3, IB: 64, IIA: 13, IIB: 2. Postoperative external and intracavitary pelvic radiation was given in 34 patients (41%). Three-year survival of these patients amounted to 86%. One-third of patients had a large primary tumour (diameter greater than 4 cm). Three-year survival rate in this subgroup of patients was 78%. Lymph node metastases were found in 14 patients (17%). Three-year survival rates for patients with and without lymph node metastases were 64% and 94%, respectively (p less than 0.0001). Results and complications of this series were compared with the current literature data and found to be comparable and sometimes even better than recent literature data. These findings may serve to advocate further centralisation of this kind of surgery in oncological centres in the Netherlands.

A full term neonate in which by accident a metabolic alkalosis was found, is described. The origin of the metabolic alkalosis was excessive vomiting by the mother during the days prior to delivery. The simplified form of the Henderson Hasselbalch equation is used to describe the factors responsible for the generation of metabolic alkalosis. Consequences for the neonate are mentioned, especially the vasoconstriction of the cerebral vessels is discussed. Treatment should be rehydration and administration of sodium-chloride.
