[Imperforate hymen; importance of inspection of the external genitalia]

Three women aged 17, 12 and 13 years presented with intermittent abdominal pain. Secondary sexual characteristics, i.e. mammae and pubic hair, were developed, but menarche had not occurred. All were found to have imperforate hymen. After incision, the symptoms disappeared. Imperforate hymen causes clinical symptoms from the time of menarche. Pubertal girls presenting with abdominal symptoms must be examined, including observation of secondary sexual characteristics and inspection of the external genitalia. This examination is often omitted because the patient and the physician are embarrassed. However, it is essential and should be carried out in a considerate manner. Excision of the hymen must be performed under general anaesthesia using a technique that will prevent secondary stenosis.

CA125 and transvaginal ultrasound monitoring in high-risk women cannot prevent the diagnosis of advanced ovarian cancer

OBJECTIVES

The main objective of screening is to identify cases of ovarian cancer in early stages. However, screening of women in the general population is ineffective due to a failure of detecting early-stage disease and high false positive rates of CA125 and transvaginal ultrasound (TVU) monitoring. The purpose of this study is to evaluate ovarian cancer screening by means of pelvic examination, serum CA125 and TVU in a consecutive series of high-risk women.

METHODS

Clinical data were collected from 132 BRCA1, 20 BRCA2 germ line mutation carriers, 72 members of hereditary breast and ovarian cancer (HBOC) families and 88 breast cancer patients from a hereditary breast cancer (HBC) family, seen between January 1996 and December 2002.

RESULTS

Among 10 women with an elevated CA125 level and a positive TVU, three screening carcinomas (one FIGO stage IC, one stage IIIB and one stage IV) and one interval carcinoma (stage IV) were detected. Five occult ovarian/fallopian tube carcinomas (two stage IA, one stage IC, one stage IIIB and one stage IV) after bilateral prophylactic (salpingo-) oophorectomy (BP(S)O) have been found in 152 women. The sensitivity, specificity, positive and negative predictive values (PPV and NPV) of the combination of CA125 and TVU were the highest (40%, 99%, 40% and 99%) followed by CA125 alone (50%, 96%, 13% and 99%), pelvic exam (40%, 98%, 21% and 99%) and TVU, separately (40%, 90%, 6% and 99%).

CONCLUSION

By combining CA125 with TVU results, a PPV of 40% was achieved. However, the diagnostic tools appear to be only sensitive in detecting ovarian cancer at an advanced stage, while three of four tumors with early-stage disease in this series had normal screening tests prior to the diagnosis.

[Adhesions of the labia minora in three young girls]

Three girls, 2, 5 and 6 years of age, had labial adhesions: one without complaints but whose mother was anxious about abnormal anatomy of the external genitalia, one with urinary problems because of pooling of the urine in the almost completely covered vagina, relapsing after surgical intervention, and one with irregular adhesions because of sexual abuse. In all three, after (repeated) application of oestrogen cream the adhesions reduced or disappeared. Adhesions of the labia minora can often be noticed under the age of 8 years and dissolve after that age during the period of progressive natural oestrogen production. Therapy consists of application of oestrogen cream on the contact surface of the labia minora. Surgical treatment is disputable and causes a high recurrence, probably higher than conservative treatment.
