Background: Israel's population is diverse, with people of different religions, many of whom seek spiritual guidance during ethical dilemmas. It is paramount for healthcare providers to be familiar with different religious approaches.

Objectives: To describe the attitudes of the three major monotheistic religions when encountering four complex neonatal situations.

Methods: A questionnaire related to four simulated cases was presented to each participant: a non-viable extremely premature infant (case 1), a severely asphyxiated term infant with extensive brain damage (case 2), a small preterm infant with severe brain hemorrhage and likely extensive brain damage (case 3), and a term infant with trisomy 21 syndrome and a severe cardiac malformation (case 4).

Results: Major differences among the three religious opinions were found in the definition of viability and in the approach towards quality of life.

Conclusions: Neonatologists must be sensitive to culture and religion when dealing with major ethical issues in the neonatal intensive care unit.

Treatment of vasculitides has progressed markedly over the past few decades. Recent therapeutic strategies in severe and refractory anti-neutrophil cytoplasmic antibodies-associated vasculitides include immunomodulating methods (e.g., plasma exchanges), products (such as intravenous immunoglobulins) and, more recently, new agents called biotherapies. Some of them (e.g., anti-tumor necrosis factor-alpha and anti-CD20 monoclonal antibodies) have achieved promising results and are now often used to treat severe cases.

Background: Genetic hemochromatosis leads to iron overload in many tissues and may lead to liver cirrhosis and hepatocellular carcinoma. Early diagnosis and therapy are crucial. Since 80–100% of hemochromatosis patients of European origin are homozygous for a cysteine to tyrosine exchange in the HFE gene at codon 282, genetic screening might be useful. Representative population studies are needed to evaluate the phenotype of people heterozygous and homozygous for the C282Y mutation.

Objective: To determine the correlation between parameters of iron metabolism and the hemochromatosis genotype in a large population-based study.

Methods: A representative population-based survey, the Diabetomobil study, analyzed 5,083 German probands. Serum transferrin saturation and ferritin levels were determined, and the C282Y mutation of the HFE gene was analyzed by restriction fragment length polymorphism- polymerase chain reaction analysis.

Results: Nine of 373 probands with a transferrin saturation > 55% (2.4%) and none of 264 randomly selected probands with a transferrin saturation £ 55% (0%) were homozygous for the C282Y mutation. Three of the nine homozygous probands had ferritin values less than 250 µg/L. The frequency of the heterozygous genotype was 8.8%, and the percentage of heterozygous probands increased with increasing levels of transferrin saturation.

Conclusion:We propose a population screening strategy with an initial transferrin saturation test, followed by genotyping for the C282Y mutation if the transferrin saturation is above 55%, regardless of the ferritin level. Heterozygous individuals with higher transferrin saturation values may be protected against iron loss but may also be more susceptible for certain liver diseases, depending on the simultaneous prevalence of other diseases.
