Hypogastric artery ligation for intractable pelvic hemorrhage.

OBJECTIVE: To assess the outcomes of bilateral hypogastric (internal iliac) ligation performed to control intractable pelvic hemorrhage and avoid hysterectomy. METHODS: A review of indications and outcomes for 117 cases of bilateral hypogastric artery ligation over 15 years (1990-2004). RESULTS: Apart from a slight lesion to the hypogastric vein, no complications were observed. Hemorrhage was effectively controlled in all 37 obstetric cases. In 13 of these cases, the uterus was preserved even when there was cervical pregnancy, placenta previa, placental abruption, uterine atony, and uterine rupture, and 4 women were delivered of mature infants. Hemorrhage was effectively controlled in 41 of 80 gynecologic cases. Prophylactic reduction of pelvic blood flow was the indication for the procedure in 39 cases, 5 of whom involving Jehovah's Witnesses adverse to blood transfusion. The uterus was preserved in only a few of the 41 controlled cases, but one woman (so far) was delivered of a mature infant. CONCLUSION: Hypogastric artery ligation was found to be indicated if (1) life-threatening pelvic hemorrhage could not be controlled by conservative methods; (2) prophylactic reduction of pelvic blood flow was needed to prevent anticipated hemorrhage; and (3) preservation of reproductive function was desired. The procedure was found to be safe and usually effective and should be taught during obstetric and gynecologic training.

Outcome of pregnancies after cold-knife conization of the uterine cervix during pregnancy.

OBJECTIVE: To determine the incidence of cervical intraepithelial neoplasia (CIN) in pregnancy and to determine the outcome of pregnancies in women treated by cold knife conization during pregnancy. METHODS: The authors retrospectively studied the cases of 19,807 pregnant patients, who presented to the 1st Department of Obstetrics and Gynecology Semmelweis University Faculty of Medicine between January 1, 1993 and December 31, 1997. Of these, there were 1,513 spontaneous abortions, 6,170 artificial abortions and 12,124 deliveries. Cytological evidence of a high-grade squamous intraepithelial lesion (LGSIL) was found in 48 pregnant patients. A low-grade squamous intraepithelial lesion (LGSIL) was found in 55 pregnant patients. All pregnant patients with HGSIL including those with satisfactory and nonsatisfactory colposcopical examinations underwent diagnostic cold knife conization during pregnancy in the second trimester. A gynecologic pathologist (Dr. Zs. Csapó) reviewed the histopathological sections. RESULTS: Overall, 44 patients had CIN, three patients had microinvasive carcinoma (FIGO stage I/A1), and one patient had neither CIN nor invasive carcinoma in the HGSIL group. Among the 48 pregnant patients with HGSIL, there were two spontaneous abortions occurring during the 21st and the 22nd gestational weeks respectively, so the pregnancy loss rate was 4.2%. Forty patients (83%) delivered at term and six patients (12.5%) at preterm. Twenty-four patients (52%) delivered vaginally and 22 (48%) by cesarean section. Comparing this data with the control group consisting of pregnant patients who had LGSIL, the difference between the two group as regards the total number of adverse pregnancy outcome cases was not significant. In the three patients with microinvasive cervical carcinoma (FIGO stage I/A1), elctive cesarean section was performed, followed by an immediate abdominal hysterectomy at term. CONCLUSION: The incidence of CIN in pregnancy was 0.22%. The incidence of microinvasive cervical carcinoma was 0.015%. Pregnant patients with CIN who underwent cold knife conization during pregnancy were not at increased risk of adverse pregnancy outcome, however they were at increased risk of cesarean delivery.

Ureaplasma urealyticum colonization in the vaginal introitus and cervix of human immunodeficiency virus-infected women.

Ureaplasma urealyticum colonization was examined in paired cervical and introital specimens from 56 untreated HIV-seropositive women. Specimens were tested for U. urealyticum by polymerase chain reaction (PCR). Peripheral blood was examined for CD4 lymphocyte counts and HIV RNA concentration. U. urealyticum was detected in the cervix of 38 (69.1%) women. Introital U. urealyticum was present in 16 (28.6%) women, all of whom were cervical-positive. Cervical motion pain was present in 40.0% of women with U. urealyticum in the introitus and cervix, 23.8% of those with only cervical U. urealyticum and 5.9% of women negative for this organism (P=0.03). There was no relation between U. urealyticum colonization and CD4 lymphocyte count. However, 64.3% of women with introital U. urealyticum had circulating HIV RNA levels > 10,000 copies per ml as compared with 28.6% of women with only cervical U. urealyticum and 7.1% of women negative for this organism (P < 0.01).

Heat shock proteins and heat shock protein-antibody complexes in placental tissues.

OBJECTIVE: The relationship between pregnancy outcome and expression of the heat shock proteins (hsps) or hsp-antibody complexes of 60kD (hsp60), 70kD (hsp70), and 90kD (hsp90) in placental tissue and circulating antibodies to hsps was evaluated. METHOD: Expression of hsp60, hsp70, and hsp90 in placentae from 12 women with preterm birth, eight with intrauterine growth restriction (IUGR), and 10 with term birth, as well as the presence of the corresponding antibodies, was investigated by a new carbocyanine double fluorescence technique. Results were compared with microbiological findings and circulating antibodies to hsps in sera. RESULTS: In each placental specimen examined, hsp60, hsp70, and hsp90 were identified. However, hsp70-antibody complexes were detected in only four of the preterm labor cases. Similarly, hsp60-antibody complexes were detected in only five preterm labor patients and in one patient with IUGR. None of the placentae contained hsp90-antibody complexes. In the preterm birth group, all patients with hsp60-antibody complexes were also positive for circulating antibodies to hsp60. The presence of hsp70-antibody complexes also correlated with hsp70 antibody in sera. CONCLUSIONS: Formation of hsp60- and hsp70-antibody complexes in the placenta may contribute to the induction of preterm birth. Women sensitized to these antibodies may be at increased risk for adverse pregnancy outcome.

[Incidence and mortality of extrauterine pregnancy in Hungary (1931-1995)].

The authors report on the changing incidence of and maternal mortality from ectopic pregnancies in Hungary between 1931 and 1995. Data of reported pregnancies were obtained from the National Institute of Statistics and the Hungarian College of Obstetricians and Gynecologists. Incidence of ectopic pregnancy was calculated as rates per 1000 live births and per 1000 reported pregnancies including live births, legally induced abortions, miscarriages, and ectopic pregnancies. Ectopic pregnancy-associated maternal mortality was examined in terms of case fatality rate and also as a proportion to the total number of pregnancy-associated maternal deaths. From 1931, when national surveillance for pregnancy begun in Hungary, to 1995, the rate per 1000 reported live births tripled from 3.4 to 11.9. Similarly, the rate of ectopic pregnancies per 1000 reported pregnancies increased by 190% from 3.7 to 6.4. In the last decade of the period studied, its proportion in the annual number of fetal deaths increased to 8.0%. Ectopic pregnancy-associated maternal deaths decreased sharply from 1931 through the late 1980's. In the last decade, its average value was 16 per 10.000 reported ectopic pregnancies. However, case fatality rate of ectopic pregnancy is still highest compared to any of the other obstetric events including induced and spontaneous abortions, and deliveries. Over the last decade, maternal deaths resulting from ectopic gestation represented 8.7% of the total maternal mortality rate. Given the increasing incidence of ectopic pregnancy together with a substantial proportion in pregnancy-related maternal mortality, study of etiology, and appropriate preventive measures are urgently needed.

Serological responses of patients with ectopic pregnancy to epitopes of the Chlamydia trachomatis 60 kDa heat shock protein.

Clinical and histopathological correlations of immunoreactivity to Chlamydia trachomatis and to epitopes of the C. trachomatis 60 kDa heat shock protein (hsp60) among women with ectopic pregnancy were evaluated in a case-control study. Serological responses to 13 synthetic peptides corresponding to major epitopes of the chlamydial hsp60 were determined in 67 women treated for ectopic pregnancy and 45 women with uncomplicated pregnancy in utero. Plasma cell salpingitis was detected in 29 (43.3%) of the ectopic patients. Its presence correlated with antibodies to two hsp60 epitopes, encompassing amino acids 260-271 and 411-422 (P = 0.02). Antibodies to these two epitopes, along with five other epitopes, also correlated with peritubal adhesion formation in ectopic pregnant patients (P < 0.01). Antibodies to epitopes 260-271 and 188-199 also correlated with a history of pelvic inflammatory disease (PID; P = 0.05). Patients with ectopic pregnancy were also more likely than their intrauterine pregnant controls to have present anti-chlamydial immunoglobulin G (P < 0.005). Women positive for both C. trachomatis and hsp60 epitope antibodies had an increased prevalence over controls of salpingitis, pelvic adhesions or history of PID (P < 0.05). In contrast, patients who were positive for only C. trachomatis antibodies or only hsp60 epitope antibodies did not differ from antibody-negative patients in each of these categories.

Obstetric anaesthesia in Hungary.

A nation-wide survey of pain relief in childbirth in Hungary was carried out in 1993. Information was provided on 104 137 deliveries in 98 units. The frequencies of different methods of pain relief for vaginal delivery were as follows: systemic opiates in 7387 cases (8.3%), epidural analgesia in 4611 cases (5.2%) and inhalational analgesia (nitrous oxide) in 4470 cases (5%). Epidural analgesia was available in 36 units (36.7%). For 71 744 vaginal deliveries (80.5%) no pain relief was provided at all. For caesarean section (n = 13240) the rate of spinal or epidural anaesthesia was 36.7%. It was concluded that despite an increasing rate of pain relief in labour elsewhere, the numbers of epidurals are still rather low in Hungary.

[A microbiology clinic in outpatient gynecologic service].

The authors report on their experiences gained at the sexually transmitted disease clinic they established at the First Department of Obstetrics and Gynecology of Semmelweis Medical University. A total of 456 patients presenting with signs and symptoms of lower genital tract infection have been examined in one year. The investigation of patients included aerobic and anaerobic culture of vaginal bacteria, vaginal smear and the identification of sexually transmitted Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasmatales and Gardnerella vaginalis. The authors conclude that a sexually transmitted disease clinic is appropriate to contribute to the prevention of horizontal and vertical spread of the sexually transmitted bacterial infections.

Detection of Chlamydia trachomatis in the female genital tract by fluorescein-labelled monoclonal antibody.

Endocervical smears were examined in a high-risk group of women using the Chlamyset "Direct Chlamydia Antigen Detection Test". From the 66 samples 42 were positive for Chlamydia trachomatis with highest incidence in the infertile group and in patients complaining of recurrent discharge. No correlation has been found between chlamydial endocervical infection and infected vaginal smears.
