摘要:

The action and clinical significance of the vaginocavernosus reflex was studied in 17 healthy women with a mean age of 36.6 years. The response of the bulbo- and ischiocavernosus muscles to rapid vaginal distension by balloon was recorded by a needle electrode inserted in each muscle and displayed on the screen of an EMG apparatus. The two cavernosus muscles contracted on vaginal distension; the amplitude of contraction increased with the increase of volume of vaginal inflation. The reflex contraction was not evoked after frequent successive or slow inflations or upon inflation of the anesthetized vagina. The latency of the reflex decreased with increased volume of vaginal inflation. The reflex cavernosus muscle contraction on vaginal distension during the sexual act seems to enhance both the clitoris and penile erection. This is believed to result from the compression exerted on both the deep dorsal vein of the penis and the erectile cavernous tissue. Also, cavernosus muscles contraction may help to milk the semen in the penile urethra into the vagina while the penis is being withdrawn from the vagina after ejaculation. Furthermore, vaginal distension by the fetal head during delivery induces cavernosus muscles contraction, which is suggested to support the head during its descent and prevent vaginal and perineal tears.

摘要:

A longitudinal evaluation of the natural killer (NK) cell activity of peripheral blood lymphocytes was performed in 17 patients with advanced ovarian cancer (treated surgically and with subsequent multiagent chemotherapy) for a median follow-up period of 32 months. At the time of primary treatment, the mean value of NK cell activity was significantly lower in patients who then had disease progression (p < 0.05) than in patients with progression-free survival. During the follow-up period, no significant modifications of the NK cell activity were observed; only at the time of clinical disease progression did the NK cell activity show a significant reduction. We conclude that the NK cell activity is a potentially important prognostic factor.

摘要:

Over a 2-year period, ultrasound-guided aspiration of painful, presumptively benign ovarian cysts was performed in 18 women < 40 years old. Aspiration was performed either transvaginally (12 patients) or transabdominally (6 patients) depending on the cyst location. Neither anaesthesia nor analgesia were used, and all patients had immediate pain relief, and escaped immediate surgical intervention. None had complications or evidence of malignant cells on cytologic examination, and all were discharged within 24 h of the procedure. The recurrence rate within 1 year of the procedure was 11.1 %. The procedure appeared to be a good and safe alternative to surgery.

摘要:

Torsion of the fallopian tube is encountered in the diseased tube. The present report describes a hematosalpinx and its tubal torsion in a virgin girl who experienced no prior predisposing factors suggested for tubal obstruction and adhesions. This rare case may highlight a new insight into pathophysiology of tubal torsion associated with hematosalpinx.

摘要:

A 31-year-old women with polycystic ovary syndrome underwent dilatation and curettage (D&C) as part of her infertility workup. Pathologic examination revealed endometrial morular metaplasia without malignant potential. Follow-up D&C had no evidence of endometrial hyperplasia or carcinoma. The diagnostic difficulties and pathogenesis are discussed.
