Relation between bone mineral content and clinical, hormonal and biochemical parameters in postmenopausal women.

We studied factors related to bone mass after a natural or surgical menopause in 73 healthy women attending the menopause clinic of a university hospital. In the natural menopause group we found inverse correlations between bone mineral density (BMD) vs. menopausal duration; BMD vs. body mass index (BMI) and BMI vs. inorganic phosphate (Pi), borderline correlations between weight vs. thyroxin (T4) and weight vs. luteinising hormone (LH) and a positive correlation between androstenedione (D4A) vs. urinary calcium (Uca). In the surgical menopause group we found some negative correlations (BMD vs. menopausal duration, BMI vs. Pi; BMI vs. dehydroepiandrosterone sulphate (DS), weight vs. DS and cortisol vs. Uca) and some positive correlations (BMD vs. free testosterone (fT), BMD vs. calcium (Ca), and BMD vs. Uca). We concluded that the serum hormone levels we measured were not useful markers of current bone mineral status.

Magnetic resonance imaging evaluation of incision healing after cesarean sections.

The purpose of this study was to examine the healing period of incision scar in myometrial wall and the normal pelvis after cesarean sections by means of MRI. In this study 17 voluntary women were examined after their first delivery with cesarean section in the early postpartum period (first 5 days), and following this, three more times in 3-month intervals. The MRI examinations were performed on a 1.0-T system (Magnetom, Siemens, Erlangen, Germany), and sagittal T1-weighted (550/17 TR/TE) and T2-weighted (2000/80 TR/TE) spin-echo (SE) images of the pelvis were obtained. During follow-up examinations incision scar tissues lost their signals within the first 3 months on both SE sequences, and little alteration was observed in the subsequent tests. Zonal anatomy of the uterus reappeared completely 6 months after cesarean sections. The time for the involution of the uterus was independent of the zonal anatomy recovery, and the maximum involution was inspected within the first 3 months. In conclusion, the maturation time of myometrial scar tissue in uncomplicated cesarean sections, which can be evaluated by the signal alterations in MRI, is approximately 3 months, whereas the complete involution and the recovery of the zonal anatomy need at least 6 months.

Congenital chylothorax.

Congenital chylothorax is a rare condition in which chyle accumulates in the pleural space because of an intrauterine obstruction or anomalies of the thoracic duct. This paper presents a case of congenital chylothorax diagnosed antepartum echographically. The patient's history revealed a previous sibling with a similar diagnosis. The baby developed respiratory distress after delivery and the diagnosis was established by thoracentesis. Computed tomography of the chest and nuclear lymphangiography were obtained to evaluate the origin of the pleural effusion, but a congenital fistula or other pathology of the thoracic duct could not be demonstrated. Management of the baby consisted of ventilatory support in the delivery room, repeated thoracentesis and thoracostomy tube drainage, total parenteral nutrition and formula containing medium-chain triglycerides. The infant was discharged six weeks after birth in good condition.
