Responses to vaginal birth after cesarean section

Recently, significant new insight has been obtained into the structure and catalytic mechanism of enzymes that convert environmental pollutants. Recent advances in protein engineering make it possible to use this information for improving the catalytic performance of such enzymes to achieve increased stability and expanded substrate range.     

Morbidity after cesarean section in obese women

The nucleotide sequences of the ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit gene (rbcL) of Glycyrrhiza glabra, G. uralensis, G. inflata, G. echinata, and G. pallidiflora have been determined to construct the phylogenetic tree. In the phylogenetic tree based on the rbcL sequences, the five Glycyrrhiza species were divided into two groups: the three glycyrrhizin-producing species G. glabra, G. uralensis, and G. inflata; and the two glycyrrhizin-nonproducing species G. echinata and G. pallidiflora. Among the three glycyrrhizin-producing species, only two nucleotide substitutions were observed between the rbcL sequence of G. glabra and G. uralensis, and the sequence of G. uralensis was identical to that of G. inflata, indicating that the three glycyrrhizin-producing species are closely related.     

Parital cutaneous necrosis of the abdominal wall after cesarean section

OBJECTIVE: The assess the incidence of tardive dyskinesia (TD) in a sample of adolescents treated with neuroleptic medication and to identify the presence of any risk factors for TD within the affected group. METHOD: A retrospective chart review was conducted for 40 cases. The Abnormal Involuntary Movement Scale (AIMS) was used to measure side effects from medication at 6-month intervals over 2 years. Drug exposure was converted to chlorpromazine (CPZ) equivalent and the presence of risk factory for TD, such as a diagnosis of affective disorder, medication noncompliance, early age of illness onset, and concomitant antiparkinsonian medication, was also noted. RESULTS: Of the 40 cases reviewed, 2 patients (5%) met diagnostic criteria for TD, and another 5 patients (12.5%) showed symptoms of TD. CONCLUSIONS: TD is a serious risk at any age. Medication noncompliance, early age of illness onset, and concomitant use of antiparkinsonian medication may increase susceptibility to TD and should be carefully monitored.     

Fertility in anovulatory patients after primary cesarean section

We report a successful surgical treatment of an infective thoracic aortic aneurysm ruptured to the left lung. A 63-year-old man who had been suffering from fever and cough showed twice of hemoptysis. Chest CT revealed a descending thoracic aortic aneurysm ruptured to the left lung. A semiemergent operation was performed. At operation, aneurysm of descending thoracic aorta was found adherent to the left lung. Aneurysmectomy with left pneumonectomy was carried out. The postoperative course of the patient was uneventful. Conceivably, in order to avoid massive intraoperative bleeding during division of dense adhesion and postoperative graft infection, concomitant lung resection is necessary.     

Vaginal birth after cesarean section in twin gestation

OBJECTIVE: We report a 10-year experience with vaginal birth after cesarean section in women with twins. STUDY DESIGN: Data were gathered from labor and delivery records and maternal and neonatal hospital charts. Women with a vertical uterine scar, a previous uterine rupture, an unrepaired dehiscence, or obstetric contraindications to labor were excluded from a trial of labor. Full-thickness uterine defects requiring intervention were classified as ruptures; all others were classified as dehiscences. RESULTS: Between Jan. 1, 1985, and Dec. 31, 1994, at Los Angeles County/University of Southern California Women's Hospital, 210 women with previous cesarean births were delivered of twins. One hundred eighteen (56%) underwent repeat cesarean delivery without a trial of labor. Ninety-two (44%) undertook a trial of labor with no uterine ruptures and no increase in maternal or perinatal morbidity or mortality. CONCLUSIONS: In women with twins a trial of labor after a previous cesarean section is a safe and effective alternative to routine repeat cesarean delivery.     

Repeated cesarean section

Pregnancies after repeated cesarean sections are often considered to carry high maternal and fetal risks. The pregnancy course, intraoperative and postoperative complications and conditions of newborns were compared between 53 patients who had two or more previous cesarean sections and 58 women sectioned for the second time. No statistical difference was found between the two groups except for intraoperative complications.     

Endometriosis in postoperative abdominal wall scar after cesarean section

Endometriosis in postoperative abdominal wall scar after cesarean section is rarely observed. In professional literature, only single cases are reported. The author presented 27 cases of this diseases. The women were treated in the Gynaecology and obstetrics Department of Medical School in Lód?, in 1985-1994. Because of the small response to pharmacological treatment, the treatment of choice was surgical of the lesion. In the article, the literature concerning the disease is presented.     

Complications for the mother in vaginal delivery after a prior cesarean section and in parturients with a planned repeat cesarean section

Over a period of 10 years (1980-1989) in the Clinic of Obstetrics and Gynaecology in Stara Zagora 740 women have delivered children after a previous caesarean operation. On the basis of this material the author has studied the vaginal delivery complications for the mother after a previous caesarean operation and in the cases of a second planned caesarean operation. The alternative and correlational analysis of the clinical data has shown that the complications for the mother in the latter group are 3 times more than those in the former group.     

Early diagnosis of uterine rupture after previous cesarean section]

A new diagnostic measure for the early detection of still uterus rupture before birth and previous cesarian section is reported. With a portio ready for birth, which permits the finger to pass readily, the possibility exists, after stripping of the membranes, to examine digitally the old caesarian scar in respect of a beginning or already existing scar dehiscence. In 112 investigated patients with this method, once a beginning, six times an incomplete and once a complete uterus rupture prior to another partus was seen. In six cases a stenosis was found in the old section region with retention of the foetal head and threatening uterus rupture.     

Althesin in cesarean section

The indications for the employment of Althesin in caesarean section are explained and a substantially favourable opinion is expressed on its clinical effects. Absence of neonatal depression is attributed both to the distribution and metabolism of the drug, and to the features of foetal circulation at term.     

Infections following cesarean section

Postpartum endomyometritis and abdominal wound infection remain the most common infectious complications following childbirth. New information now suggests that incipient infection of the myometrium explains why patients develop postpartum endometritis despite antibiotic prophylaxis. Clinical predictors of postpartum endometritis continue to suffer from low sensitivity. However, use of a Gram stain of the amniotic fluid may be helpful in identifying a subset of women that may benefit from a therapeutic course of antibiotics initiated immediately after cesarean section. Broad-spectrum antimicrobial therapy is the mainstay of therapy for postpartum endometritis. Two newer extended spectrum cephalosporins, cefotetan and ceftizoxime, appear to be as effective as cefoxitin in the treatment of these infections. Abdominal wound infection is a common cause of antimicrobial failure in patients treated for post-cesarean endomyometritis. The genital mycoplasmas, usually resistant to the penicillins and cephalosporins, are commonly isolated from infected wounds following cesarean section. Wound infection surveillance has been shown to decrease infection incidence rates by providing feedback to the operating surgeon.     

Late post-partum hemorrhage after cesarean section due to rupture of a false aneurysm of the uterine pedicle

We report a 14 year-old girl with a huge adenomatous goiter in the left lobe in the thyroid gland reaching the aortic arch with elevated thyroglobulin. The tumor grew rapidly for two years since the initial diagnosis as an euthyroid hemilateral goiter. Ultrasonography revealed multinodular tumors and magnetic resonance imaging made clear the lower expanding site of the tumor. We recommend careful follow up of hemilateral diffuse goiters by ultrasonography for earlier detection of nodular changes as seen in our case.     

Antibiotic prophylaxis in cesarean section

BACKGROUND: To investigate the guidelines for patient selection and drug regimens for application of antibiotic prophylaxis in relation to cesarean section in the maternity clinics in Denmark. METHODS: A questionnaire to all the Danish maternity clinics that perform cesarean section, concerning indications for application of antibiotic prophylaxis and antibiotic regimens to patients undergoing acute and elective cesarean section. RESULTS: All departments (n = 48) returned the questionnaire. Twenty departments (46%) provided written guidelines for antibiotic prophylaxis. Four departments (8%) used antibiotic prophylaxis to elective cesarean sections, 25 departments (52%) applied antibiotics to all emergency sections. In the presence of the rupture of membranes or prolongation of labor (> 12 hrs) 58% and 63% of the departments applied antibiotic prophylaxis, respectively. The most infrequent first choice drug was cefuroxim, employed by 27 departments (56%). Concerning timing, 21 departments (44%) applied antibiotics after cord clamping and 13 departments (27%) before incision. CONCLUSION: We propose a nation-wide prospective investigation on the rate of infections associated with cesarean section to set up rational guidelines for antibiotic prophylaxis.     

Acupuncture analgesia and cesarean section

The application of acupuncture anesthesia in obstetrics is discussed and reviewed. Of 14 patients delivered by cesarean section under acupuncture, 8 (57%) felt no pain, and 6 did not go through the entire procedure without other supplementary anesthesia. The failure and success rates are reviewed. It is suggested that the technique be evaluated further because with acupuncture the fetus and mother are completely protected from the secondary effects of general regional anesthesia.
