Vacuum extraction and herpes simplex virus infection.

OBJECTIVE: To search for an association between delivery by vacuum extraction and an increased neonatal risk for herpes simplex virus (HSV) infection. METHODS: In a cross-sectional, descriptive, controlled study, the study (vacuum extraction) and control (spontaneous delivery) groups each included 50 consecutive women with no history of HSV infection. Cultures for HSV were obtained from the genital tracts of all parturient women and the scalps of their newborns. RESULTS: Following operative vaginal delivery, two newborns (4%) had scalp vesicles and cultures were positive for HSV for both mothers and newborns; two newborns (4%) had scalp vesicles and cultures were negative for HSV; and two newborns (4%) without scalp vesicles had cultures positive for HSV. Following spontaneous delivery, cultures were positive for HSV for four women and their newborns (8%). CONCLUSION: Herpes simplex virus isolated from the scalps of newborns may often result from colonization rather than infection.

Relationship between uterine contractions and serum magnesium levels in patients treated for threatened preterm labour with intravenous magnesium sulphate.

We aimed to correlate the assessment of preterm uterine activity with serum magnesium levels in women with threatened preterm labour. The observational study involved twelve women receiving intravenous magnesium sulphate for threatened preterm labour. Mean gestational age at initiation of therapy was 26.9+/-2.9 weeks. Mean cervical dilatation at initiation of therapy was 1.5 cm. Serum magnesium levels and evaluation of uterine contractions by external tocograph were assessed twice daily. Presence or absence of contractions was analysed for correlation with plasma magnesium levels. Eighty-eight measurements were analysed. The mean serum magnesium levels were 1.9+/-0.5 mmol/l and 1.9+/-0.3 mmol/l in the presence (n=22) or absence (n=66) of contractions, respectively. The difference did not reach statistical significance. No correlation was found between serum magnesium levels and presence of contractions (P=0.3, logistic regression odds ratio 1.1, 95% confidence interval of 0.6-2.0). The abolition of premature uterine contractions during intravenous magnesium sulphate therapy does not correlate with serum magnesium levels.

Thermal death kinetics of egg and third instar Mediterranean fruit fly (Diptera: Tephritidae).

Two developmental stages of Ceratitis capitata (Wiedemann), 24-h-old eggs and third instars, 8 d after oviposition, were subjected to thermal exposures in a heating block system, at various temperatures of 46, 48, 50, and 52 degrees C to determine the thermal death kinetics of the insects. At these temperatures, 100% mortality was achieved by exposure of 300 C. capitata larvae for 60, 15, 4, and 1 min, respectively. The 0.5 order kinetic model had the best fit to the survival ratio for all the treatment temperatures, hence it was used for the prediction of the lethal times. The thermal death time (TDT) curves showed that the third instars were more heat-resistant than eggs, especially at the two low temperatures (46 and 48 degrees C). Under temperature-time combinations that did not result in complete kill, the thermal mortality for eggs was also significantly higher than that for third instars. The activation energy values calculated from the TDT curves were 490.6 and 551.9 kJ/mol, respectively, for thermal death of eggs and third instars.

Is antibody screening in Rh (D)-positive pregnant women necessary?

OBJECTIVE: Hemolytic disease of the fetus and of the newborn can be caused by incompatibility of maternal and fetal erythrocytes for Rh (D) or other blood type antigens. Routine antibody screening is advocated in all pregnant women, irrespective of whether they are Rh (D)-positive or Rh (D)-negative, to look for clinically significant alloantibodies other than Rh (D) that might cause hemolytic disease of the newborn. The purpose of this study was to assess the incidence of blood type antibodies other than Rh (D) in pregnant women attending for prenatal care in a typical urban population. METHODS: A retrospective analysis was undertaken of the charts of all pregnant women followed throughout their entire pregnancy at our Women's Health Center from 1 January 1999 to 30 April 2002. RESULTS: There were 1265 pregnant women included in the study: 465 had blood type A (36.7%), 269 type B (21.3%), 424 type O (33.5%) and 107 type AB (8.5%). A total of 1156 were Rh (D)-positive (91.4%) and 109 were Rh (D)-negative (8.6%). Of the Rh (D)-positive women, 522 (41.3%) underwent routine antibody screening in the first trimester. Only one woman (0.2%) had a positive antibody screen. Of the 109 Rh (D)-negative women, one (0.9%) had a positive third trimester screen with a negative first trimester screen. CONCLUSION: Routine antibody screening of Rh (D)-positive women is probably not warranted from a clinical cost-benefit perspective.

Assessment of a newer technique for cesarean section.

We present a new method for cesarean section that predominantly employs blunt techniques. We used it in 51 patients having a first cesarean section and compared the results with 51 matched controls having a standard technique first cesarean section.

Value of vaginal culture in management of acute vaginitis.

OBJECTIVE: To evaluate the relative contribution of clinical assessment and vaginal discharge cultures in the treatment of acute vaginitis. METHODS: A prospective observational study of 75 consecutive sexually active women with acute vaginal symptoms was undertaken. Each patient underwent an evaluation that included a standardized history, interview a thorough pelvic examination and vaginal culture. The treatment was administered based upon patient symptomatology and macroscopic appearance of vaginal discharge. RESULTS: There was an agreement between initial diagnosis and culture isolates in 38 patients (50.6%). Of the 75 enrolled women 9 have not returned for reevaluation 8 days after initiation of the treatment. Fifty three (80.3%) of the remaining 66 women were free of symptoms 8 days after initiation of the treatment. The remaining 13 women were treated successfully in accordance with the vaginal culture result. CONCLUSION: A high cure rate of acute vaginitis could be achieved based upon physical examination. Vaginal cultures are valuable in initial therapy failures.

Adnexal torsion with a paraovarian cyst in a teenage girl.

Adnexal torsion with a paraovarian cyst in adolescent or premenarchal girls is extremely rare and very difficult to diagnose before surgery. We identified three published cases of the disorder in adolescent or premenarchal girls. Our patient, a 12.5-year-old girl, is the fourth. The cyst was excised and the adnexa untwisted at laparoscopy. High awareness and timely laparoscopy contributed to conservation of the adnexa in our young patient.

Disseminated intravascular coagulopathy in pregnancy: thorough comprehension of etiology and management reduces obstetricians' stress.

In pregnancy and puerperium disseminated intravascular coagulopathy may accompany abruptio placenta, intrauterine fetal demise with retained dead fetus, amniotic fluid embolism, endotoxin sepsis, preecalampsia with HELLP and massive transfusion. Clinical signs and symptoms of DIC can include oozing from venipuncture sites and/or mucous membranes, red cell lysis from activation of the complement system, hemorrhage from coagulopathy and possible uterine atony, hypotension from hemorrhage and/or bradykinin release, and oliguria from end-organ insult and hypovolemia/hypotension. Treatment of DIC consists of replacement of volume, blood products, and coagulation components and cardiovascular and respiratory support with elimination of underlying triggering mechanism.
