[Study on prevalence of upper and lower airways disorders in woodworkers, using data from medical surveillance reports and exposure registers].

Objectives: To evaluate correlations between exposure to wood dust, upper airways symptoms and lung function.

Methods: We have analysed medical surveillance reports of 197 woodworkers with a median wood dust TWA exposure of 2.1 mg/m3.

Paracrine regulation of menstruation.

Endometrial proliferation, secretion, vascular neoformation and modification to shedding is under direct and/or indirect control of steroid hormones. The progressive modification of the endometrial architecture is due to its growth and differentiation. The new tissue regenerates monthly from a 2-5 mm to a 12-18 mm of complex tissue until it sheds under a co-ordinated network of bioactive molecules produced and activated during the menstrual cycle.

Treatment strategies of the borderline ovarian tumors.

The present study was undertaken to establish the role of surgical procedures, histologic type, and stage of the tumor on the survival rate of patients with borderline ovarian tumors in a 5 to 15 years of follow-up. Data reported in the literature have shown the low malignancy of this cancer and that only the stage, but not the pathological diagnosis, is significantly influencing the survival rate of the patients. After 5 years, the survival rate of patients with tumors of stage I to stage II is 98.

Uterine Contractility in Patients with Endometriosis.

Uterine contractility was evaluated in 30 women, 16 with endometriosis and 14 controls. Two catheters were introduced into the uterine cavity, one next to the fundus and the other in proximity of internal os. They were connected to a pressure transducer that transforms mechanical events into an electrical signal, and analyzed by a system dedicated to this purpose.
