Ultrasonography in the detection of cervical incompetency

In 80 pregnancies with clinical and ultrasonic signs of cervical incompetency, the length of the cervix and the thickness of the anterior wall of a lower uterine segment have been evaluated ultrasonically. We have also measured the width of the endocervical canal and studied the prolapse of fetal membranes (with fetal parts) into the endocervical canal. We evaluated these same parameters in 80 healthy pregnancies. The length of the cervix, the thickness of the anterior wall of a lower uterine segment, and the width of the endocervical canal were followed longitudinally in the patients from the 10th to the 36th gestation week. No statistically significant differences between age groups were found. In four age groups at risk for cervical incompetency, cervical lengths and wall thickness were significantly different (p less than 0.001) from those in comparable controls. Forty-five percent of the patients in the at-risk group, with cervical cerclage, delivered at 37.3 (range: 32 to 41) weeks and 6.25% of pregnancies ended in abortion when the amniotic membrane herniated into the cervical canal, with or without some part of the fetus.     

Impaired estrogen-induced uterine insulin-like growth factor-I gene expression in the streptozotocin diabetic rat

Summary Circulating somatomedin-C/insulin-like growth factor-I levels are low in the diabetic rat and unresponsive to exogenous growth hormone. However, the nature of this defect in growth hormone action remains unclear and there is little data on insulin-like growth factor-I gene expression in response to other stimuli and in non-hepatic tissues where insulin-like growth factor-I may have important paracrine and/or autocrine actions. We have previously shown that 17-beta estradiol stimulates uterine insulin-like growth factor-I expression in the ovariectomised rat. In this report uterine and hepatic insulin-like growth factor-I gene expression have been examined in the streptozotocin-diabetic rat. Serum insulin-like growth factor-I concentrations were significantly reduced in diabetic rats compared to normal rats (0.72±0.08 vs 1.23±0.05U/ml, p<0.0005) and hepatic insulin-like growth factor-I mRNA abundance was similarly reduced in diabetic rats to 49±5% of that seen in non-diabetic intact rats (p<0.005). In contrast, uterine insulin-like growth factor-I mRNA abundance was not significantly reduced in diabetic rats compared to control rats (76±12%, p = NS). Although both diabetic and non-diabetic rats demonstrated a significant increase in uterine wet weight following a single injection of 17-beta estradiol the increase in uterine insulinlike growth factor-I expression was significantly less marked in diabetic rats. Acute administration of insulin together with estradiol had no significant effect on serum insulin-like growth factor-I concentrations or hepatic insulin-like growth factor-I mRNA abundance; however, the uterine insulin-like growth factor-I response was significantly (p<0.01) augmented. The observations reported here demonstrate that hepatic insulin-like growth factor-I gene expression is markedly reduced in the diabetic rat and that the estradiol-induced uterine insulin-like growth factor-I response is significantly diminished, consistent with the hypothesis that there is a defect in insulin-like growth factor-I gene activation in the diabetic rat.

Neglected rupture of the Achilles tendon treated with peroneus brevis transfer: A functional assessment of 5 cases

The purpose of this study was to review the clinical results of 5 patients who underwent repair of a chronic Achilles tendon rupture using a combination of peroneus brevis transfer and plantaris tendon augmentation. The technique belongs to the group of local tendon transfer procedures making use of the transferred peroneus brevis tendon as strengthening material together with the plantaris tendon as suturing material. There were 4 males and 1 female with an average age of 49.4 years and an average time to presentation postinjury of 19.8 weeks (range 5-40 wk). All patients underwent Cybex strength testing before and approximately 1 year after surgery. This testing demonstrated a postoperative improvement in peak plantarflexion torque (Newton-meters/body weight) in all cases. The peak torque of plantar flexion increased in all patients (range, 21%-410%). Four patients were found to have an increase of the dorsal flexors peak torque (range, 31%-290%), whereas one patient showed a decrease (-37%). No patient experienced wound closure complications, postoperative pain, or functional limitations. In spite the possibility of residual lateral ankle instability, we found this modification to be a valuable innovation that offers a very good functional result, low morbidity, technical advantages to the surgeon and, most important, a durable and satisfactory result for the patients.
