Background: The arrival of 610,000 new immigrants to Israel from the former Soviet republics accounted for 58% of the population growth in the early 1990s.

Objective: To compare the coronary angiographic findings and risk factors between the new immigrants and local Jewish and Arab patients in this era of cost containment.

Methods and Results: A total of 550 consecutive patients - 314 Jews, 95 new immigrants and 141 Arabs - were catheterized and analyzed during a 5 month period in 1995. Of this group 403 were males (73%). The mean age was 63.6±10.2 years among new immigrants, 62.4±9.4 among Jews, and 55.1±10.9 among Arabs (P<0.05). Immigrants, including those under age 60, had the highest prevalence of multivessel disease (88.7%). Arabs had a high prevalence of single vessel disease (34.6%) and a low prevalence of multivessel (65.4%) and left main coronary disease (5.6%). Age, gender, risk factors and ethnic origin in descending order were determinants of the extent of coronary angiographic disease as revealed by multiple regression analysis.

Conclusion: New immigrants had the most extensive angiographic coronary involvement, while Arab patients were younger and had less severe coronary artery disease. More intensive risk factor modification may have a major impact on disease progression particularly in the new immigrant subgroup. 

Background: For centuries talismans and amulets have been used in many cultures for their legendary healing powers.

Methods: We asked the parents of every child (Jews and Arabs) admitted to the Pediatric Intensive Care Unit over a 2 month period to complete a questionnaire, which included demographic data on the patient and the family, the use of talismans or other folk medicine practices, and the perception of the effects of these practices on the patient’s well-being. A different questionnaire was completed by the ICU staff members on their attitude toward the use of amulets.

Results: Thirty percent of the families used amulets and talismans in the ICU, irrespective of the socioeconomic status of the family or the severity of the patient’s illness. Amulets and talismans were used significantly more by religious Jews, by families with a higher parental educational level, and where the hospitalized child was very young. The estimated frequency of amulet use by the children’s families, as perceived by the staff, was significantly higher than actual use reported by the parents. In Jewish families the actual use of amulets was found to be 30% compared to the 60% rate estimated by the medical staff; while in Moslem families the actual use was zero compared to the staff’s estimation of about 36%. Of the 19 staff members, 14 reported that the use of amulets seemed to reduce the parents' anxiety, while 2 claimed that amulet use sometimes interfered with the staff’s ability to carry out medical treatment.  

Conclusions: The use of talismans in a technologically advanced western society is more frequent than may have been thought. Medical and paramedical personnel dealing with very ill patients should be aware of the emotional and psychological implications of such beliefs and practices on patients and their families.

Background: In trials comparing different formulations of measles vaccine, excess non-specific mortality occurred in female children who received high titer vaccine. These findings suggest a gender-specific effect of measles vaccine.

Objectives: To determine whether gender differences exist in the rates of adverse reactions and morbidity in the month following immunization with measles-containing vaccine, and to evaluate whether there is a gender-specific association between the humoral immune response to measles vaccination and post-vaccination morbidity.

Methods: Parents completed questionnaires on the health status of 755 infants aged 15-20 months, during the month preceding and the month following the measles-mumps-rubella vaccination. Blood samples were tested for measles antibody titers in a subsample of 237 infants.

Results: After controlling background morbidity in the infants, the relative risk of fever and rash following vaccination was 2.35 in females and 1.36 in males. The geometric mean antibody titers against measles were similar in both sexes and there was no significant association between antibody titer and post-vaccination morbidity in either sex.

Conclusions: Our findings demonstrate higher rates of adverse effects in females following vaccination with MMR vaccine, irrespective of the humoral response. This study emphasizes the need to consider possible gender differences when evaluating new vaccines.

Background: Cholestasis is a frequent problem in patients on total parenteral nutrition. Cisapride has a prokinetic effect on the biliary system, but its effect on hepatic excretory function is unknown.

Objectives: To study the effect of cisapride on TPN-induced cholestasis in a rat model.

Methods: Bile flow and bile salt secretion rate were measured in rats given TPN. There were four groups of 8 to 13 animals each. After a one hour baseline period during which all four groups received i.v. saline infusion, two groups received a TPN solution for another 2 hours, while saline was infused in the two control groups.

At the beginning of the second hour, 2 mg/kg cisapride was injected i.v. as a bolus into one experimental and one control group. Bile was collected from the common bile duct.

Results: At the end of the third hour, TPN caused a significant reduction in bile flow (P<0.02) and bile salt secretion rate (P<0.001) (61.24 vs. 50.74 µl/min/kg, and 1.173 vs. 0.799 µmol/min/kg, respectively). Addition of cisapride abolished the cholestatic effect of TPN.

Conclusions: Cisapride has a protective effect against TPN-associated cholestasis. This may have clinical significance, and further studies are warranted.

Background: Bronchiolitis caused by respiratory syncytial virus is one of the major causes of hospitalization in young children, especially during the winter.  Recent evidence has shown that pharmacological treatment, especially nebulized epinephrine, in addition to the traditional supportive treatment, can alleviate symptoms and shorten hospitalization, but this approach is not yet widespread.

Objectives: To determine whether the management of bronchiolitis in Israel is moving toward a stronger emphasis on pharmacological care.

Methods: A questionnaire on the diagnosis and management of bronchiolitis was completed by 27 heads of pediatric departments throughout Israel.  The questionnaire dealt with the frequency of usage of diagnostic and selected therapeutic procedures.

Results: Chest X-ray and arterial blood gases are commonly used as a diagnostic aid in more than 75% of the departments, and antibiotics are prescribed routinely in 24%.  Corticosteroids are still in use: 48% use systemic steroids, and 19% nebulized steroids.  Nebulized epinephrine is used in 22% of the departments, while nebulized beta-agonists are used frequently in two-thirds of the departments.

Conclusions: Despite convincing data that beta-agonists and steroids have no positive effect on the outcome of bronchiolitis on the one hand, and that nebulized epinephrine has advantages in children on the other, we found significant use of the former two agents and sparse use of the latter.  Greater awareness is needed among pediatricians, and measures should be introduced to incorporate the new recommendations, with further study of the effect of the old and new drugs on bronchiolitis.

 

Background: In our experience, secondary enuresis nocturna is a common complaint among children after a motor vehicle accident.  However, as these children are often brought for examination as part of an insurance compensation claim, this complaint is not always reliable.

Objective: To describe a series of children in whom secondary enuresis occurred after a motor vehicle accident.

Methods and Results: Five children were brought to our clinic for evaluation of secondary nocturnal enuresis. Review of past history revealed a car accident preceding the onset of the enuresis. All but one had additional behavioral symptoms typical of post-traumatic stress disorder. Four children had evidence of head trauma, and one had psychological but no physical trauma. 

Conclusions: Nocturnal enuresis can occur after a motor vehicle accident due either to purely psychological trauma or organic head trauma. While nocturnal enuresis is generally attributed to organic causes, psychological mechanisms also play a significant role.

Background: Previous studies have published controversial results regarding a connection between Helicobacter pylori infection and colorectal cancer. One possible mechanism is increased gastrin secretion in subjects infected with H. pylori, insofar as gastrin is known to be a trophic factor for the colonic mucosa.

Objectives: To investigate a possible role of gastrin secretion in H. pylori infection associated with colorectal cancer, and determine whether H. pylori infection is a factor in this disease.

Methods: The serum gastrin levels and the presence of H. pylori IgG antibodies were measured in 51 colorectal cancer patients and 51 control subjects. The cancer patients were also tested for carcinoembryonic antigen and CA 19-9.

Results: H. pylori IgG antibodies were found in the serum of 41 (80.4%) of the cancer patients compared to 32 (62.7%) of the control subjects (P=0.05). A significant correlation was found between CA 19-9 (γ=0.3432, n=49, P=0.01) and seropositive H. pylori IgG antibodies in the serum of the cancer patients (odds ratio 2.43, and 95% confidence limit 0.99-5.95), but none between CEA and H. pylori IgG antibodies nor between the serum gastrin level and the presence of colorectal cancer.

Conclusions: The results of this study indicate a significant association between seropositive H. pylori IgG antibodies and elevated CA 19-9 in colorectal cancer patients, but no correlation between the serum gastrin level and the presence of this cancer. H. pylori seropositivity is more prevalent in patients with colorectal cancer.
