Creatine kinase as a biochemical marker in diagnosis of placenta increta and percreta.

We describe 1 case of placenta increta and 1 of placenta percreta, both associated with elevated maternal serum creatine kinase concentration. In patients with placenta previa and ultrasonographic findings of an abnormally adherent placenta, an unexplained elevation in maternal serum creatine kinase level should alert the clinician to the possibility of placenta increta or placenta percreta, with an attendant increase in maternal morbidity.

Is removal of the tube mandatory after coagulation in ectopic pregnancies.

Laparoscopic treatment of ectopic pregnancy is gaining wide acceptance. We report a new simple laparoscopic technique involving grasping the tube with forceps and coagulating on both sides of the ectopic pregnancy site, leaving the fertilized ovum in situ. This method is suitable for multiparous women and women who request tubal sterilization. Sixteen patients (mean age 32.6 +/- 4.4 years) were treated by using this method. The mean duration of hospitalization was 1.94 +/- 1.12 days. No complications occurred.

Beta-HCG concentration in peritoneal fluid and serum in ectopic and intrauterine pregnancy.

OBJECTIVE: To evaluate the significance of beta-HCG levels in peritoneal fluid and serum in the diagnosis of ectopic pregnancy. STUDY DESIGN SETTING: Obstetrics and Gynecology department of a regional general hospital. SUBJECTS: Sixty-two women who presented with a differential diagnosis of ectopic pregnancy vs. nonviable intrauterine pregnancy. INTERVENTIONS: All patients underwent D & C and culdocentesis. beta-HCG was measured in simultaneously obtained peritoneal fluid (PF) and serum (S), and the PF/S ratio calculated. RESULTS: Twenty-three patients had an ectopic pregnancy (Group I). All 23 had higher beta-HCG concentrations in the PF than in the serum, with a mean PF/S ratio of 19.1 +/- 16.9. Twenty-four patients had an intrauterine pregnancy (Group II). The beta-HCG levels in the PF and serum were similar (mean PF/S 1.1 +/- 0.2). The difference in PF/S ratio between groups I and II was statistically significant (p < 0.001). CONCLUSION: The measurement of beta-HCG in peritoneal fluid and serum is a useful diagnostic tool in differentiating ectopic from intrauterine pregnancy.

Silver halide fiber optic radiometric temperature measurement and control of CO2 laser-irradiated tissues and application to tissue welding.

Tissue heating by laser irradiation has attained importance in many clinical applications. Accurate temperature measurements of laser-irradiated tissues are difficult to achieve, and experiments have produced conflicting results. Fiber optic radiometry allows temperature measurement of laser-irradiated tissues by remote sensing of the emitted infra red (IR) radiation. We have developed an IR fiber optic radiometer capable of accurate tissue temperature measurements (+/- 0.2 degrees C) and utilized it to monitor and control the heating of tissues by CO2 laser irradiation. Tissue temperature control of +/- 2.5 degrees C was achieved. This system was used to control tissue temperature during CO2 laser-assisted welding of urinary bladders in rats. The strength of the welds was recorded for different welding temperatures. A temperature of 55 degrees C was found to be optimal.

Sonographic diagnosis of fetal congenital cataracts.

Five fetuses with congenital cataracts diagnosed in utero by ultrasound are reported. The fetuses, who were between 14 and 27 weeks' gestation, also had other severe malformations. The sonographic features of the cataracts are presented.

Is cesarean section necessary for delivery of a breech first twin?

Eighty-two pregnancies involving a breech first twin were retrospectively analyzed over two study periods during which the cesarean section rates were 20.9 and 94.9%, respectively. The neonatal and maternal morbidity in both study periods was compared. There were no neonatal deaths during either study period and no cases of interlocking twins among patients delivered vaginally. Neonatal morbidity was unrelated to the mode of delivery. The incidence of maternal fever was, however, significantly higher in the cesarean section group compared with the vaginal delivery group (p < 0.001). Our study suggests that vaginal delivery of selected twin gestations with a breech first twin should be an alternative to cesarean delivery.

Breech presentation after cesarean section: always a section?

A retrospective review of 71 breech deliveries after previous cesarean was done to determine the need for repeat cesarean section. Twenty-four (33.8%) women were allocated to the elective repeat cesarean section group and forty-seven (66.2%) patients were allocated to a trial of labor group. Thirty-seven (78.7%) were delivered of their infants vaginally. A total of 37 of the 71 women (52.1%) had successful vaginal deliveries. Neonatal morbidity did not differ for women who were delivered vaginally or by cesarean section. Maternal febrile morbidity was significantly higher in the cesarean section group than in the vaginal delivery group (p less than 0.001). On the basis of these data, a trial of labor seems reasonable in carefully selected cases of breech presentation after a previous cesarean section.
