Background: Pregestational diabetes mellitus (PGDM) carries a significantly elevated risk of adverse maternal and fetal outcomes. There is evidence that certain interventions reduce the risk for adverse outcomes. Studies have shown that a multi-disciplinary approach improves pregnancy outcomes in women with PGDM.

Objectives: To determine pregnancy outcomes in women with PGDM using a multi-disciplinary approach.

Methods: We retrospectively reviewed consecutive women with pregestational type 1 and type 2 diabetes who were monitored at a high-risk pregnancy clinic at the Sheba Medical Center. Clinical data were obtained from the medical records. All data related to maternal glucose control and insulin pump function were prospectively recorded on Medtronic CareLink® pro software (Medtronic MiniMed, Northridge, CA).

Results: This study comprised 121 neonates from 116 pregnancies of 94 women. In 83% of the pregnancies continuous glucose monitoring (CGM) sensors were applied during a part or all of the pregnancy. Pregnancy outcomes among women who were followed by a multi-disciplinary team before and during pregnancy, and during labor and puerperium resulted in better glucose control (hemoglobin A1c 6.4% vs. 7.8%), lower risk for pregnancy induced hypertension/preeclampsia (7.7% vs. 15.6%), lower birth weight (3212 g vs. 3684 g), and lower rate of large size for gestational age and macrosomia (23.1% vs. 54.2% and 3.3% vs. 28.4%, respectively), compared to data from European cohorts.

Conclusions: The multi-disciplinary approach for treating women with PGDM practiced in the high-risk pregnancy clinic at the Sheba Medical Center resulted in lower rates of macrosomia, LGA, and pregnancy induced hypertension compared to rates reported in the literature.

Background: Congenital factor VII deficiency is a rare recessive autosomal bleeding disorder with a wide spectrum of clinical manifestations.

Objectives: To compare the clinical and laboratory findings in Jewish and Bedouin patients with factor VII deficiency.

Methods: The clinical and laboratory findings of patients with factor VII deficiency treated at Soroka Medical Center, a tertiary hospital in Israel, from 2005 to 2015 were analyzed regarding blood factor levels, illness severity, treatment administration, and disease outcome.

Results: Seventy-eight patients were enrolled (1:13,000 of the population in southern Israel) of whom 26 were diagnosed with severe factor VII deficiency (1:40,000). Sixty (76.9%) patients were Jewish and 18 (23.1%) were Bedouin. In univariable analysis, Bedouin patients exhibited a more severe illness, with significantly higher complication and fatality rates, and required more preventive treatment than the Jewish patients.

Conclusions: The prevalence of congenital factor VII deficiency (including severe deficiency) in the Jewish and Bedouin populations of southern Israel is higher than previously reported. The clinical spectrum of the disease was found to be more severe in the Bedouin population.

Background: Gaucher disease is the most prevalent inherited disorder among Ashkenazi Jews (carrier frequency of about 6%) and six mutations account for about 96% of their mutant alleles. Two mutations, N370S and R496H, have been reported only in mildly affected or asymptomatic patients, Due to the rarity of R496H, it was recommended that it be excluded from screening programs. 

Objectives: To verify the frequency and trace the origin of Gaucher mutations in screened individuals whose Ashkenazi ethnicity was confirmed by the birthplace of their grandparents.

Methods: We conducted a retrospective analysis of the screened results for the period 2006–2011. Mutations were identified by restriction analysis, Tag-It^TM detection system, Pronto® diagnostic kit and Nanogen technology (NanoChip® 400).

Results: The heterozygote frequency of eight mutations was estimated in a cohort of 16,910 alleles. Two mutations, N370S and R496H, were the most frequent in our population. However, while the occurrence of N370S carriers was similar to other reports (1:19.4), that of R496H carriers was considerably elevated (1:207). Examination of the screened individuals' ethnicity showed a significant difference in the distribution pattern of the country of origin between the carriers of these two mutations.

Conclusions: The origin pattern differences between the two groups of heterozygotes might reflect a separate geographic region of introduction for various mutations. As a result, secondary subgroups could be formed within the Ashkenazi population. This might clarify the dissimilarities in the occurrence of R496H mutation reported by various centers. 

Background: The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed.

0bjectives: To report our results with percutaneous elimination of CBD stones from the gallbladder through the papilla.

Methods: During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube).

Results: Each patient had one to three CBD stones measuring 7–14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures.

Conclusions: Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.
 

Background: Iron deficiency is the most prevalent anemia in infants and is known to be a major public health problem.

Objective: To examine mothers’ knowledge and adherence with recommendations regarding iron supplementation and assess their association with the prevalence of anemia in infants.

Methods: Data on 101 infants and mothers of infants born between November 2000 and February 2001, living in a small Jewish town in southern Israel, were collected using a structured questionnaire and the infants’ medical charts. Anemia was defined as serum hemoglobin less than 11 g/dl. Independent variables include socioeconomic data, mothers' knowledge, and adherence to treatment as reported by them. Chi-square test was used to analyze categorical variables, t-test was used for continuous variables, and hemoglobin was tested at 9–12 months of age.

Results: Of the 101 infants in the study, 47% had serum hemoglobin under 11 g/dl. Of the mothers, 62 (62%) were partially or completely non-compliant with iron supplementation; 34 (34%) had low level of knowledge regarding anemia. Multivariate logistic regression analysis revealed a significant and inverse relationship between the presence of anemia and the level of maternal knowledge (odds ratio = 5.6, 95% confidence interval 1.6–9.7; P = 0.006) and reported adherence with iron supplementation (3.2, 1.1–9.7; P = 0.04) after controlling for confounding factors: maternal education, socioeconomic status, breastfeeding, and meat consumption.

Conclusions: The presence of iron deficiency anemia in infants in southern Israel is inversely affected by the level of maternal knowledge of anemia and adherence to iron supplementation. Low level of knowledge is also directly related to low adherence.
 

Objective: To report a unique hereditary, juvenile onset, craniocervical predominant, generalized dystonia and parkinsonism affecting four members of one family.

Family Description: A father and three of his four daughters presented to us over the past 30 years with a similar picture of generalized dystonia, starting in the craniocervical region in the second or third decade of life. They later developed moderate parkinsonism, mainly manifesting bradykinesia, rigidity and abnormal postural reflexes. Biochemical and genetic tests excluded Wilson's disease, Huntington's disease and Oppenheim's dystonia.

Conclusion: This is a new type of familial dystonia-parkinsonism where the craniocervical dystonic symptoms are most prominent in the early stages while parkinsonism becomes the predominant problem later in life. A search for the genetic mutation in this family is underway.
