Structure of human cervical mucus correlation with plasma ovarian hormone levels.

In studying the structural changes of human cervical mucus during the ovulatory cycle, they have been observed to be directly related to ovarian hormone changes. Mucus structural changes, if taken according to their sequence during the cycle, clearly express the anatomic and functional events occurring in the ovary. If each structure is considered separately, only the mucus of the preovulatory period can be considered an indication of the corresponding ovarian processes, presenting peculiar morphologic characteristics. The observation of a similar morphologic appearance in the mucus of the early follicular and luteal phases leads one to believe, in spite of the influence of totally different hormone levels, in the likely existence of a mechanism of interference between estrogens and progesterone during the postovulatory period of the cycle.

[Radiographic aspect of aneurysmal cysts of the spine].

Aneurysmal bone cyst is a pseudoneoplastic skeletal disorder. The material of the Tumor Center at the Rizzoli Orthopaedic Institute refers to 198 cases, 25 (12.6%) with spinal localization. The X-ray pattern of aneurysmal bone cyst is represented by an osteolytic area more or less evidently involving the vertebra, with frequent extension to the surrounding soft tissues. Its maturing evolution is typical, and occurs both spontaneously and after surgical and/or radiation therapy.

Recurrent posterior instability of the shoulder: surgical treatment.

A total of 11 cases of posterior instability of the shoulder surgically treated by simple capsuloplasty or associated with reinforcement of the posterior wall by bone graft or muscle transposition were reviewed. Accurate selection and preoperative evaluation of the patient when choosing surgery is very important. For surgery to succeed prolonged postoperative immobilization and an intense rehabilitative program to be initiated prior to surgery are necessary. Generalized ligamentous hyperlaxity constitutes a negative factor in prognosis, so that it is important to associate capsuloplasty with posterior bone block, in an attempt to avoid the risk of recurrence as further surgery would have an unfavorable outcome.
