The impact of a nationwide hands-on workshop on the diagnostic rates and management of obstetrical anal sphincter Injuries in Israel.

AIM: The aim was to evaluate the influence of a half day, hands-on, workshop on the detection and repair of obstetric anal sphincter injuries (OASIs). METHOD: Starting in February 2011, hands-on workshops for the diagnosis and repair of OASIs were delivered by trained urogynaecologists in departments of tertiary medical centres in Israel. The structure of the hands-on workshop resembles the workshop organized at the International Urogynecological Association annual conferences. Participants included medical staff, midwives and surgical residents from each medical centre. We collected data regarding the rate of OASIs, 1 year before and 1 year following the workshop, in 11 medical centres. The study population was composed of parturients with the following inclusion criteria: singleton pregnancy, vertex presentation and vaginal delivery. Pre-viable preterm gestations (< 24 weeks), birth weight < 500 g, stillborn, and those with major congenital anomalies, multifoetal pregnancies, breech presentations and caesarean deliveries were excluded from the analysis. RESULTS: In the reviewed centres, 70 663 (49.3%) women delivered prior to the workshop (pre-workshop group) and 72 616 (50.7%) women delivered following the workshop (post-workshop group). Third- or fourth-degree perineal tears occurred in 248 women (0.35%) before the workshop, and in 328 (0.45%) following the workshop, a significant increase of 28.7% (P = 0.002). The increase in diagnosis was significant also in women with third-degree tears alone, 226 women (0.32%) before the workshop and 298 (0.41%) following the workshop, an increase of 28.3% (P = 0.005). CONCLUSION: The detection rate of OASIs has significantly increased following the hands-on workshop. The implementation of such programmes is crucial for increasing awareness and detection rates of OASI following vaginal deliveries.

The effect of rLH supplementation to the GnRH-antagonist protocol on endocrine dynamics in the advanced reproductive age.

PURPOSE: To explore serum endocrine dynamics, specifically LH levels, following rLH supplementation to rFSH following GnRH-antagonist treatment in the advance reproductive age. METHODS: Women were prospectively and similarly treated employing rFSH and the flexible GnRH-antagonist protocol, while rLH was supplemented only to the study group. Serum FSH, LH, E2, and P were evaluated throughout the follicular phase. Three strategies were a priori planned to examine endocrine dynamics among women enrolled. RESULTS: While serum LH drop were similar before GnRH-antagonist stimulation, it dropped more times in the control group compared to the study group. Among women receiving rFSH only, serum LH levels dropped ≤2, ≤1 and ≤0.5 mIU/mL in 71.4, 46.4, and 28.6% of cases, while this occurred only in 38.7% (P = 0.01), 6.5% (P = 0.0004) and 3.2% (P = 0.007) of women receiving combined rFSH and rLH treatment, respectively. The same trend was found when serum LH dropped in at least two occasions following the GnRH-antagonist administration. Conversely, serum LH diagrams throughout the follicular phase did not differ between the two groups. Furthermore, individual area under the curve values of LH, E2, and P was similar between the two groups following GnRH-antagonist initiation. CONCLUSIONS: Different strategies to explore LH dynamics following the GnRH-antagonist administration have resulted in diverse results, implying the need for a consensus definition of LH threshold for adequate folliculogenesis and steroidogenesis. Such action would pave the way for understanding which groups of patients may benefit from rLH supplementation.

Glycemic control and clinic attendance of emerging adults with type 1 diabetes at a transition care clinic.

BACKGROUND: Emerging adulthood is a challenging period for diabetes management. Our aim was to determine whether a dedicated transition clinic for emerging adults with type 1 diabetes can improve glycemic control and visit attendance. METHODS: An observational study of 53 emerging adults (30 males) treated during 2010-2014 in a newly established transition clinic. The clinic was operated jointly by pediatric and adult endocrinologists and included a transition coordinator. Data collected included the source of referral, HbA1c levels, frequency of visit attendance, and acute complications. For 27 patients who had attended the pediatric clinic at the same medical center, data from up to 2 years preceding the transition were also collected. Patients filled the Diabetes Quality of Life-Youth questionnaire at the transition and 1 year later. RESULTS: Mean ± SD age at the transfer to the transition clinic was 22.1 ± 2.7 years; mean disease duration was 8.4 ± 5.0 years. Follow-up duration at the transition clinic was 1.2 ± 1.1 years. Mean HbA1c levels decreased from 67 mmol/mol (95 % CI 63-72) [8.3 % (95 % CI 7.9-8.7)] at transfer to 57 mmol/mol (95 % CI 52-63) [7.4 % (95 % CI 6.9-7.9)] after 1 year (p < 0.001). Thirty-six patients (68 %) attended three or more visits during their first year in the transition clinic. The impact of diabetes on quality of life, disease-related worries, and life satisfaction did not change significantly during 1-year attendance in the transition clinic. CONCLUSIONS: A dedicated transition clinic for emerging adults, with tailored support according to the developmental needs of emerging adulthood, showed improved glycemic control and visit attendance.

Inhibition of inflammation may enhance nitric oxide availability in patients undergoing bariatric surgery for weight loss.

BACKGROUND: Weight loss surgery is the most effective treatment for morbid obesity. The mechanisms underlying the beneficial cardiovascular effects are poorly understood, although inhibition of inflammatory markers has been demonstrated. We hypothesized that anti-inflammatory and antioxidative stress reactions are responsible for the beneficial effects of bariatric surgery that have been shown in clinical trials. METHODS: The inflammatory system was studied by measuring mRNA levels of E-selectin, tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and in a cell line (HUVEC-CS) of human umbilical vein endothelial cells that were incubated for 4 h with pools of serum, collected before and 3 months after surgery, from 20 women who underwent bariatric surgery for weight loss. The oxidative stress pathway was examined by mRNA expression of NADPH oxidase (P22(phox) ), paraoxonase (PON2), superoxide dismutase 2 (SOD2), glutathione peroxidase (GPx) and catalase following incubation of the cells for 4 h with serum pools. The nitric oxide (NO) pathway was studied by measuring mRNA levels of inducible NOS and endothelial NOS and by determining nitrite and nitrate levels. To study the functional behaviour of endothelial cells under stress, primary human umbilical vein endothelial cells (PECs) were incubated with the serum pools for 48 h, with lipopolysaccharide (LPS) for the last 4 h. RESULTS: The inflammatory system: incubation of HUVEC-CS cells with serum from women who underwent bariatric surgery led to a significant decrease in mRNA expression of E-selectin and IL-6 postsurgery. Stimulation of PECs with LPS in the presence of serum from women who underwent bariatric surgery caused a more significant difference in E-selectin and TNF-α mRNA expression before and after surgery. The antioxidant system: incubation of HUVEC-CS cells with serum from women who underwent bariatric surgery did not lead to any difference in mRNA expression of P22(phox) , PON2, SOD2, GPx or catalase. Stimulation of PECs with LPS showed that obese women had higher levels of P22(phox) , PON2 and the antioxidant enzymes SOD2, GPx and catalase before and after surgery, compared to the control group. The NO pathway: HUVEC-CS cells incubated with serum from women who underwent bariatric surgery secreted higher nitrite/nitrate levels compared to presurgery serum (P = 0.04). CONCLUSIONS: Inhibition of inflammation and enhanced availability of NO 3 months after bariatric surgery could partly explain the beneficial effects of surgery for weight loss.

Teaching internal medicine in the community.

BACKGROUND: Teaching Internal Medicine is mainly hospital-based. Chronic diseases are treated mostly in community-based ambulatory care. This study describes our experience during the first year of teaching Internal Medicine in the community, with a focus on chronic disease management. METHODS: This was an observational study describing the content of clinical exposure and the feedback from students after a two-week clerkship in community health centers. RESULTS: Over a period of three months, 54 students spent two weeks in health centers singly or in pairs. The disciplines covered were: Endocrinology, Gastroenterology, Pulmonology, Rheumatology and Geriatrics. In their feedback, the students most frequently noted knowledge acquired in the management of diabetes, infectious diseases and cardiology. The teaching content was determined by the case-mix of patients. The spectrum of conditions was wide. Students who were used to more structured hospital-based study found it difficult to cope with this mode of learning by discovery. DISCUSSION: Future research should concentrate on the transition between the different modes of learning as students move from the hospital to the community setting.

The use of continuous glucose monitoring systems in a pediatric population with type 1 diabetes mellitus in real-life settings: the AWeSoMe Study Group experience.

AIMS: The aim of the study was (a) to compare annual glycemic control in pediatric patients with type 1 diabetes mellitus (T1DM) who used a healthcare-funded continuous glucose monitoring system (RT-CGMS) to that of those who performed self-monitoring blood glucose (SMBG) only, in a real-life setting, and (b) to define parameters associated with compliance and glycemic control. METHODS: A total of 149 youth with T1DM (52.3 % females), mean age 11.8 ± 3.6 years, and 83 in the CGMS group were followed prospectively for 12 months. Glycemic control parameters and compliance to RT-CGMS were assessed periodically. RESULTS: Glycemic parameters did not differ significantly between the groups during follow-up periods. The time spent with RT-CGMS decreased and only 38 % used it for more than 75 % of the time during the 12 months (consistent users). Mean HbA1c decreased by 0.27 % in consistent users and increased by 0.21 % among intermittent users (used RT-CGMS less than 75 % of time), p = 0.013. Consistent users were younger 10. 6 ± 4.2 vs. 12.5 ± 3.6, p = 0.07, and had higher frequency of SMBG at baseline, 10.6 ± 4.9 vs. 6.3 ± 2.8, p = 0.011. CONCLUSIONS: The adoption of RT-CGMS was low, even in a healthcare system that funds its use. Caregivers should consider patient characteristics when recommending RT-CGMS use.

Pregnancy outcome after laparoscopy or laparotomy in pregnancy.

STUDY OBJECTIVE: To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy. DESIGN: Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2). SETTING: Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals. PATIENTS: Three hundred eighty-nine pregnant women. INTERVENTION: Laparoscopy or laparotomy for various indications. MEASUREMENTS AND MAIN RESULTS: Of 192 laparoscopies performed, 141 were during the first, 46 during the second, and 5 during the third trimester; respective figures for 197 laparotomies were 63, 110, and 24. No intraoperative complications were reported for either procedure. Six and 25 women had complications after laparoscopy and laparotomy, respectively. There was no significant difference in abortion rates between groups. Mean gestational age at delivery and mean birthweight were comparable between groups. No significant difference was found in frequency of fetal anomalies between groups or when compared with the Israel register of anomalies. CONCLUSION: Operative laparoscopy seems to be as safe as laparotomy in pregnancy.

In-utero development of the fetal colon and rectum: sonographic evaluation.

OBJECTIVE: To construct a normal range for the internal diameter of the fetal descending colon and rectum during gestation. SUBJECTS AND METHODS: This was a prospective, cross-sectional study including 379 healthy pregnant women with normal singleton pregnancies at 19-40 weeks of gestation. Measurements of the fetal descending colon (maximum internal diameter) and the fetal rectum (at the level of the bladder, measuring the anteroposterior diameter), were performed by high-resolution transabdominal sonography. RESULTS: Adequate bowel measurements were obtained in all 379 fetuses. The diameter of the descending colon and rectum plotted as a function of gestational age had a sigmoid curve; the curve estimation was expressed by a cubic regression equation with R(2) of 0.848 and 0.831, respectively (P < 0.0001). The normal mean and the 95% prediction limits were defined. CONCLUSION: The present data provide a normal range of fetal bowel (descending colon and rectum) diameters from the early second trimester of pregnancy onwards. They may allow intrauterine assessment of the development of the fetal colon and may serve as reference values in the detection of anomalies of the fetal bowel.

Normal cardiac flow velocities at 14-16 weeks of gestation measured by transvaginal ultrasound.

OBJECTIVE: Doppler ultrasound has been used to study the flow velocities through the valves and arteries of the fetal heart. Using transvaginal sonography, we sought to determine normal values for flow velocities through the fetal heart valves at 14-16 weeks of gestation. METHODS: Eighty-seven normal fetuses were examined. The flow velocity waveforms were visualized using Doppler ultrasound with the sample volume calipers placed just distally to the four fetal valves. Peak E- and A-wave velocities were recorded for the tricuspid and mitral valves and peak systolic flow velocities were recorded for the ascending aorta and pulmonary arteries. Linear regression for comparison of flow velocities with gestational age was performed. RESULTS: There was no significant correlation between any of the velocities and gestational age. CONCLUSIONS: Flow velocities through the fetal cardiac valves remain unchanged at 14-16 weeks of gestation as measured by transvaginal Doppler sonography.

Nuchal fold thickness at 14-16 weeks' gestation as measured by transvaginal sonography.

OBJECTIVE: To establish normal values of fetal nuchal fold thick-ness at 14-16 weeks of gestation by transvaginal sonography. METHODS: Transvaginal sonography was used to measure nuchal fold thickness in 182 normal pregnancies at 14-16 weeks of gestation. Nuchal fold thickness was measured as the distance from the outer skull bone to the outer skin surface in the transverse axial image in the suboccipital-bregmatic plane of the head. RESULTS: There was no significant association between nuchal fold thickness and gestational age (r = 0.084; P = 0.258). The mean (standard deviation) was 2.2 (0.5) mm and the 95th centile was 3.0 mm. CONCLUSIONS: The 95th centile of nuchal fold thickness measured by transvaginal sonography at 14-16 weeks is 3.0 mm.

Endometrial ablation using hysteroscopic instillation of hot saline solution into the uterus.

OBJECTIVE: To evaluate the clinical effectiveness and safety of endometrial ablation by hysteroscopic instillation of hot saline using the Hydro-Therm-Ablator (HTA) system. METHODS: A total of 14 patients with menorrhagia, underwent the HTA procedure under general anethesia. Follow up of 9-18 months is reported. Three patients had undergone tubal ligation years before the procedure and one underwent it immediately after HTA at the same session. RESULTS: One procedure was cancelled due to technical problems, and roller-ball ablation was performed. There were no procedure related complications. A total of 11 patients reported significant reduction in bleeding, or amenorrhea, 9-18 months after the HTA procedure. One patient, although eumenorrheic after the ablation, considered the procedure a failure and requested hysterectomy. One patient with menorrhagia 3 months after the procedure, had a second HTA ablation and is now amenorrheic. CONCLUSIONS: This series of patients who underwent HTA ablation had successful reduction of menorrhagia to oligomenorrhea or amenorrhea.

Cerebral lateral ventricular atrial diameter of male and female fetuses at 20-24 weeks' gestation.

OBJECTIVE: To determine if the lateral ventricular atrial diameter differs between male and female fetuses at 20-24 weeks' gestation. DESIGN: Prospective study. METHODS: The transverse diameter of the ventricular atrium was measured from inner wall to inner wall for a total of 202 pregnant women with 105 male fetuses and 97 female fetuses. RESULTS: The mean diameter of the ventricular atrium for the 202 fetuses was 4.96 +/- 0.96 mm (range, 2.1-8.4 mm). The 105 males had a mean diameter of 4.95 +/- 0.98 mm and the 97 females a mean diameter of 4.97 +/- 0.94 mm. There was no statistical difference between the sexes. CONCLUSIONS: In our population, there was no difference between ventricular atrial diameter in male and female fetuses at 20-24 weeks' gestation.

Increased progesterone/estradiol ratio in the late follicular phase could be related to low ovarian reserve in in vitro fertilization-embryo transfer cycles with a long gonadotropin-releasing hormone agonist.

OBJECTIVE: To gain insight into the physiologic as well as the clinical significance of premature luteinization in the long gonadotropin-releasing hormone agonist (GnRH-a) cycles and to evaluate whether it may be a manifestation of low ovarian reserve. DESIGN: Prospective evaluation. SETTING: A university-affiliated reproductive medicine unit. PATIENT(S): Seventy-six consecutive infertile women. INTERVENTION(S): The long GnRH-a protocol was used for IVF-ET treatment. MAIN OUTCOME MEASURE(S): Women in the study were prospectively evaluated in their first cycle of treatment and were divided into those with (study group) or without premature luteinization (control group). Premature luteinization was defined as P/E2 ratio of more than 1 on the day of hCG administration. RESULTS(S): Thirty-one (41%) of the women in the study demonstrated premature luteinization. Patients' characteristics were comparable between the two groups. Late follicular P/E2 ratio was significantly and considerably higher in the study as compared to the control group, 2.4 +/- 1.7 and 0.7 +/- 0.2, respectively. Ovarian reserve parameters including day 3 FSH, E2 level on hCG day, total amount of hMG, number of follicles, oocytes, and embryos were significantly inferior in the study as compared to the control group. P levels on hCG day were significantly higher in the study as compared to the control group, 1.9 +/- 0.7 ng/mL and 1.2 +/- 0.6 ng/mL, respectively. However, LH levels on hCG day did not differ between the groups, 1.4 +/- 0.7 mIU/mL and 1.2 +/- 0.7 mIU/mL, respectively. The clinical pregnancy rate was significantly lower in the premature luteinization group as opposed to controls, 13% and 42%, respectively. CONCLUSION(S): Premature luteinization, defined as late follicular P/E2 >1, in long GnRH-a cycles seems to adversely affect clinical outcome. Our findings in this setting support the notion that premature luteinization could be related to low ovarian reserve and that this manifestation is not necessarily an LH-dependent event.

Diabetes in pregnancy: efficacy and cost of hospitalization as compared with ambulatory management--a prospective controlled study.

BACKGROUND: Pregnant diabetic women are often subjected to frequent and prolonged hospitalizations to assure tight glycemic control, but in recent years attempts have been made at ambulatory control. The financial and social advantages of ambulatory management are obvious, but no report to date has prospectively compared its efficacy with that of hospitalization. OBJECTIVES: To evaluate the efficacy and cost of ambulatory care as compared to repeated hospitalizations for management of diabetes in pregnancy. METHODS: We conducted an 8 year prospective controlled study that included 681 diabetic women, experiencing 801 singleton pregnancies, with commencement of therapy prior to 34 gestational weeks. During 1986-1989, 394 pregnancies (60 pregestational diabetes mellitus and 334 gestational diabetes mellitus) were managed by hospitalization, and for the period 1990-1993, 407 pregnancies (61 PGDM and 346 GDM) were managed ambulatorily. Glycemic control, maternal complications, perinatal mortality, neonatal morbidity and hospital cost were analyzed. RESULTS: There was no difference in metabolic control and pregnancy outcome in women with PGDM between the hospitalized and the ambulatory groups. Patients with GDM who were managed ambulatorily had significantly lower mean capillary glucose levels, later delivery and higher gestational age at induction of labor as compared to their hospitalized counterparts. In this group there were also lower rates of neonatal hyperbilirubinemia, phototherapy and intensive care unit admissions and stay. The saved hospital cost (in Israeli prices) in the ambulatory group was $6,000 and $15,000 per GDM and PGDM pregnancy, respectively. CONCLUSIONS: Ambulatory care is as effective as hospitalization among PGDM patients and more effective among GDM patients with regard to glycemic control and neonatal morbidity. This is not only more convenient for the pregnant diabetic patient, but significantly reduces treatment costs.

The effect of thrombophylaxis on pregnancy outcome in patients with recurrent pregnancy loss associated with factor V Leiden mutation.

OBJECTIVE: To observe the effect of thrombophylaxis on pregnancy in women with a history of unexplained recurrent pregnancy loss also carrying the factor V Leiden mutation. METHODS: Between 1 January and 31 December 1996, activated protein C (APC) resistance and factor V Leiden mutation were prospectively measured in 56 nonpregnant women, with a history of two or more unexplained recurrent pregnancy losses. During the same study period, seven women carrying the factor V Leiden mutation conceived, and were subsequently followed throughout their pregnancy. Subcutaneous low molecular weight heparin (LMWH, enoxaparin, 40 mg/day) and oral low dose aspirin (100 mg/day) were administered throughout the pregnancies, starting at early first trimester. Ultrasound and Doppler umbilical and fetal middle cerebral arterial flow studies were performed in the second and third trimesters, and the course and outcome of the pregnancies were documented. RESULTS: Activated protein C resistance and factor V Leiden were found in 20 (36%) and 12 (21%) women of the study, respectively. Five of the seven pregnancies occuring progressed uneventfully to term with normal fetal growth, normal Doppler flow studies and uneventful neonatal outcome. Two of the seven women had early missed abortions. CONCLUSIONS: Thrombophylaxis, beginning in early pregnancy, in women with unexplained recurrent pregnancy loss associated with factor V Leiden mutation, seems to be safe and allow normal fetal development and good neonatal outcome. To prove the efficacy of thrombophylaxis by LMWH and low dose aspirin in this setting prospective controlled studies seem to be justified.

Activated protein C resistance and factor V Leiden mutation can be associated with first-as well as second-trimester recurrent pregnancy loss.

PROBLEM: To examine whether the occurrence of activated protein C resistance (APCR) and factor V Leiden mutation differs in women with first- compared to women with second-trimester unexplained recurrent pregnancy loss. METHOD OF STUDY: Seventy eight consecutive women with two or more unexplained post-embryonic recurrent pregnancy losses and 139 fertile women with at least one successful pregnancy and no abortions were prospectively investigated for APCR and the factor V Leiden mutation. No women were pregnant at the time of investigation. APCR was defined as APC sensitivity ratio (APC SR) of < or = 2.0. All patients with an APC SR < or = 2.4 were investigated for the factor V Leiden mutation. Women in this study were divided into three groups. Group A included only women with a history of recurrent first-trimester embryonic loss (37 women) and Group B included women with second-trimester abortions with or without additional first-trimester abortions (41 women). Group C included the controls (139 women). RESULTS: APCR and factor V Leiden mutations were significantly more prevalent in all recurrent pregnancy loss patients in this study as compared to controls. 38%(30/78) and 19%(15/78) in contrast to 8% (11/139) and 6% (8/139), respectively. All three groups in the study were comparable regarding age, parity, and number of living children, whereas Groups A and B were also comparable regarding gravidity. Mean APC SRs were significantly higher in Group C as compared to Groups A and B. The incidence of APCR was significantly higher in Groups A and B, as compared to controls, 27 and 49% in contrast to 8%, respectively. Moreover, the incidence of the factor V Leiden mutation was significantly higher in Groups A and B as compared to Group C, 16 and 22% as distinct from 6%, respectively. The incidence of APCR was higher in Group B as compared to Group A, 49% in contrast to 27%, with borderline significance: however, the factor V Leiden mutation did not significantly differ between the two groups. CONCLUSIONS: APCR and factor V Leiden are associated with unexplained recurrent pregnancy loss. The occurrence of APCR and factor V Leiden seems to be linked to post-embryonic first-trimester as well as second-trimester recurrent pregnancy loss. The significance of acquired, non-heritable APCR in recurrent fetal loss patients, especially in the second-trimester aborters, is still to be determined.

Acute adrenal insufficiency during pregnancy and puerperium: case report and literature review.

UNLABELLED: Acute adrenal dysfunction during pregnancy is rare. Nevertheless, adrenal insufficiency can present as an adrenal crisis, and may be life threatening. There is a wide range of clinical symptoms and signs, and the differential diagnosis is challenging. A full adrenal and pituitary evaluation, both structural and hormonal, must be performed to reach the correct diagnosis, and appropriate treatment must not be delayed. A case is presented of acute adrenal insufficiency that occurred 24 hours after a cesarean delivery. The initial symptoms included hypoglycemic seizures and coma. The workup, both hormonal and structural, revealed isolated adrenocorticotrophic hormone deficiency. This considers this case and reviews the differential diagnosis, diagnostic workup, and the treatment of adrenal dysfunction in pregnancy and the puerperium, as well as the obstetric outcome in women suffering from this disorder. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader will be able to understand the various presentations of hypopituitarism, the various etiologies of this condition, and the appropriate work up and management of a patient with hypopituitarism.
