Effects of clomiphene citrate on cervical mucus: analysis of some influencing factors.

A multicenter study was performed to investigate the effects of a standard dose of clomiphene citrate (100 mg/day from day 5 of the cycle for five days) on the quality of cervical mucus. A total of 82 cervical mucus samples from 60 infertile patients (15 with secondary amenorrhea, 16 with delayed ovulation, 15 with anovulatory cycles, 14 with oligomenorrhea) was examined on the day of maximum follicular diameter. As a control we studied 54 cervical mucus samples from 47 patients with documented tubal sterility or infertile partners, who had spontaneous cycles with normal rhythm. Cervical mucus was unfavorable in 59% of the treatment cycles compared with 11% of the control cycles. Clomiphene citrate's antiestrogenic effect on cervical mucus was found to be related to the length of time between the last drug administration and the day of maximum follicular diameter (delta days), since cervical mucus was favorable in 64% of the cycles with a delta days more than 6 and in only 16% of the cycles with a delta days of 6 or less. Clomiphene citrate thus seems able to decrease cervical mucus quality. This could be one of the causes of the discrepancy between the rates of ovulation and pregnancy reported in patients treated with this drug.

[Anatomic contribution to the study on the variety of fibrous formations of the arm in humans].

The authors have examined an anatomical preparation of a human upper limb preserved in the Anatomical Museum in Bologna. The specimen was formed by bone, fibrous formations, musculus biceps brachii and musculus coracobrachialis. The soft parts were kept in situ and dried by mummification. The humerus showed abnormalities at its proximal extremity (Fig. 1) and the muscles displayed fibrous varieties: a) a fibrous sheet (Fig. 1, 2) connected the caput brevis of the musculus biceps brachii to the articular capsule of the shoulder joint; b) an aponevrosis (Fig. 1, 3) connected the musculus coracobrachialis to the same articular capsule and the humerus. These observations were discussed from an evolutionary and functional point of view.

Poor reproductive prognosis in severe teratozoospermia with a predominant sperm anomaly.

A retrospective examination of the semen analyses performed in our clinic from January 1979 to September 1986 revealed that approximately 15% of the patients were affected by severe teratozoospermia (greater than 80% abnormal forms and greater than 5 x 10(6) sperm/ml). In approximately 8% of these cases, a single predominant anomaly (same defect in greater than 50% of the sperm) was reported and confirmed by subsequent analyses (n = 37). The types of monomorphic teratozoospermia encountered in this study included round head (n = 6), amorphous head (n = 16), small head (n = 6), tapering head (n = 2), pin head (n = 1) and midpiece anomaly (n = 6). The clinical data suggest that familial genetic factors are probably involved in round head-monomorphic teratozoospermia, whereas testicular factors may be associated with amorphous head-monomorphic teratozoospermia. No matter what type of monomorphic teratozoospermia, the data in vivo (no pregnancies recorded in the follow-up period ranging from 2-8 years) and in vitro (negative SPAs) suggest a poor prognosis for the couples affected by this syndrome.

Communicating uteri: description and classification of a new type.

A case of bicornuate-bicervical communicating uterus with atresia of the right hemicervix is reported. This cannot be included in any of the nine groups of Toaff's classification of uterine malformations proposed in 1984, and should be classified as a new, tenth type.

Second-look laparoscopy in the treatment of endometriosis.

The results of second-look laparoscopy were compared with subjective symptomatology and findings at pelvic exploration in 36 patients who had received conservative treatment for endometriosis. In the 14 patients given pharmacologic treatment, second-look laparoscopy demonstrated active endometriosis in 57.1%, whereas pelvic pain was present in 64.3% and gynecologic examination was positive in 28.6%. In the 22 patients who underwent surgery, active endometriosis was detected by second-look laparoscopy in 31.8%, whereas 40.9% reported pelvic pain and pelvic examination was positive in 31.8%. Thus clinical signs and symptoms were unreliable in the diagnosis of endometriosis recurrence, whereas laparoscopy was indispensable. It should be programmed for 6 months from the end of medical treatment and 12 months after surgery; however, if the pain symptomatology recurs, then laparoscopy is performed immediately.

Partial seizures and migraine.

Epilepsy and migraine, despite some common features, have quite different pathophysiological mechanisms. Studies carried out on large population samples have shown that the relationships between migraine and epilepsy may be of the following type: associated attacks, with migraine and seizures occurring quite independently of one another; combined attacks, with the two types of attacks succeeding one another in time; basilar artery migraine with seizures and marked EEG abnormalities; benign epilepsies with occipital discharges, migraine and intercalated seizures. We report four cases of particular interest.

Effect of a new oral antiandrogen-estrogen combination on the endometrium: histological and ultrastructural scanning electron microscopy study.

Endometrial biopsies were obtained in 12 volunteers between 18 and 35 years old who had used SHB 209 AE oral contraceptive during the previous six months. Three main types of endometrial patterns were observed: proliferative, very similar to a normal proliferative phase; early secretory: similar to early postovulatory endometrium; late secretory: characterized by diffuse predecidual changes in the stroma. At SEM after one week a great prevalence of nonciliated cells was observed. During the 2nd and the 3rd week, the endometrial surface appears still flattened with scanty glandular outlets.

Degree of endosalpingeal deciliation (by S.E.M.) in hydrosalpinx is not prognostic for post-surgical fertility.

In 21 infertile patients, operated on for bilateral hydrosalpinges, multiple tubal biopsies, removed during surgery, were studied by light microscopy and scanning electron microscopy. Compared with control biopsies, taken from 12 fertile women, all cases but one showed flattening or loss of major and minor mucosal folds and epithelial deciliation. However postsurgical fertility rate, after 1-3 years follow-up, is not proportional to the percentage of ciliated cells.

The management of hydrocolpos.

Three cases of hydrocolpos observed in the Milan Department of Obstetrics and Gynecology and of Pediatric Surgery are described. Two of them were cases of simple imperforated hymen whereas the third had a vaginal obstruction associated with microcephaly and polydactily. The diagnosis was based on vaginography and urography and the treatment on resection of the vaginal membrane in two cases and in laparatomic Leadbetter-Politano's operation in the third. The Authors stress the importance of a very early diagnosis for a definitive treatment and a good prognosis and also the interest of a follow-up of these patients.
