Recent reports from different countries have shown an increasing incidence of insulin-dependent diabetes mellitus (IDDM, type I diabetes). In Israel, several surveys of the incidence of IDDM have been conducted. During 1996, a national juvenile diabetes register was founded by specialists in endocrinology, and the Israel Center for Disease Control (ICDC). This is the first report of the national incidence of IDDM in the 0-17 year age group in Israel. New cases of juvenile diabetes were reported using an anonymous form. The ICDC was responsible for data collection, control and statistical analyses. During 1997, 162 new cases of diabetes mellitus were reported in the age group 0-17, 154 of them diagnosed as IDDM. The annual incidence in the total population of Israel in 1997 was 7.7/100,000. Age-specific incidence was 7.3/100,000 in boys and 8.1 in girls. A family history of IDDM was found in 14.3% of the cases. Incidence was higher for Jews (9.2/100,000) than Arabs (3.6/100,000). Among Jews, children whose fathers were born in Yemen had the highest incidence and those born to fathers born in Israel the lowest incidence. IDDM incidence rates for 1997 are higher than reported in previous surveys. It will be possible to draw conclusions regarding possible trends in incidence from data to be gathered in the next few years.
BACKGROUND: Based on previous survey data, an increased incidence of IDDM (type 1 diabetes) among children and adolescents was reported by the Israel IDDM Registry Group in 1997. Similar increases have been reported from various countries in past years. This paper presents incidence rates of IDDM among 0-17 years old population for 1998. METHODS: Methods of data collection were reported in a previous paper. Briefly, this is a population based anonymous registry. New cases are reported to the ICDC by all the centers for type I IDDM diabetes in Israel. Crude incidence rates and specific sex, age and population group rates are presented. RESULTS: During 1998, 186 new cases of IDDM were reported in the age group 0-17 years. The annual incidence rate in the total population of Israel in 1998 was 9.1 cases per 100,000. Incidence rates for 1998, were higher for Jews (9.5 per 100,000) than for Arabs (8.0 per 100,000). Among Jews, children of Ethiopian origin had the highest incidence rate (18.2 per 100,000), but this finding is based on six new cases. Children of Asian and North African origin had the lowest incidence rate (5.7 per 100,000). Age-specific incidence rates are different in boys and girls. A close family history of IDDM was found in 8.1% of the cases. CONCLUSION: IDDM incidence rates for 1998 are 15% higher than those reported for 1997. The increase in rates was steeper for Arabs (74%) than for Jews (4.4%), leading to a smaller difference between Jews and Arabs than reported in 1997. Verification of the apparent increase in incidence will be possible by the examination of data from the registry in the next few years.
The data collected for the second edition of the Directory of Medical Research in Israel and the Israel Biomedical Database have yielded very relevant information concerning the distribution of investigators, publication activities and funding sources. The aggregate data confirm the findings of the first edition published in 1996 [2]. Those facts endorse the highly concentrated and extensive nature of medical research in the Jerusalem area, which is conducted at the Hebrew University and its affiliated hospitals. In contrast, Tel Aviv University, whose basic research staff is about two-thirds the size of the Hebrew University staff, has a more diffuse relationship with its clinical staff who are located at more than half a dozen hospitals. Ben-Gurion University in Beer Sheva and the Technion in Haifa are smaller in size, but have closer geographic contact between their clinical and basic research staff. Nonetheless, all the medical schools and affiliated hospitals have good publication and funding records. It is important to note that while some aspects of the performance at basic research institutions seem to be somewhat better than at hospitals, the records are actually quite similar despite the greater burden of clinical services at the hospitals as compared to teaching responsibilities in the basic sciences. The survey also indicates the substantial number of young investigators in the latest survey who did not appear in the first survey. While this is certainly encouraging, it is also disturbing that the funding sources are apparently decreasing at a time when young investigators are attempting to become established and the increasing burden of health care costs precludes financial assistance from hospital sources. The intensity and undoubtedly the quality of medical research in Israel remains at a level consistent with many of the more advanced western countries. This conclusion is somewhat mitigated by the fact that there is a decrease in available funding and a measurable decrease in scholarly activity at a time when a new, younger generation of investigators is just beginning to become productive. In closing, we wish to stress that the collection of data for the Biomedical Database is a continuing project and we encourage all medical researches who may not have contributed relevant information to write to the Office of the Chief Scientist or contact the office by email.
In Europe and the U.S., awareness of interpersonal traumatization has disappeared and reappeared, seemingly connected to socio-historical conditions. The authors wanted to explore this phenomenon in Israel, a complex, multicultural, society that has yet to know peace. Content analysis of a professional journal, the Israel Journal of Psychiatry, was the method of choice. This journal has existed since the fifteenth year of Israel's existence and, because it is published in English, is in active dialogue with the rest of the world. Striking parallels were found between the timing and focus on traumas in the published articles and the socio-cultural context.
Assessing the prevalence of relevant risk factors among young adults is a critical step in the process of preventing atherosclerotic cardiovascular diseases (ASCVD) later in life. The Israel Defense Force Periodic Health Examination Center performs a routine check-up for subjects aged 25-45 years. Medical history, physical examination notes, laboratory results and ECG tracings are recorded, computerized and processed to form the Young Adults Periodic Examinations in Israel (YAPEIS) database. Data representing 31,640 subjects (27,769 males and 3871 females) examined between the years 1991-1999 were analyzed. The prevalence of documented risk factors for ASCVD were evaluated. The results of all parameters were graded categorically as low, moderate or high and the Framingham risk score was calculated. Fifty-one percent of the study participants were found to be overweight (body mass index > or = 25 kg/m2), 8.5% had high systolic blood pressure and 14.6% had high diastolic blood pressure. The prevalence of hypercholesterolemia and hyperglycemia was found to be 44.7 and 9.7%, respectively. Thirty-two percent of the subjects smoked cigarettes, and 76.7% reported not performing any routine physical activity. Furthermore, 31.8% had a Framingham score indicating a greater than 5% risk for developing a coronary event within the next 10 years. As expected, the prevalence of these risk factors increased with age and were found to be less frequent among females. Thus we conclude that many young Israeli adults hold significant risk factors for future ASCVD. Many of these risk factors are modifiable, and risk behavior is often amenable to alteration. Awareness to the high prevalence of risk factors among young adults should spark vigorous health-promotion programs as well as screening, education, and interventional measures aimed at altering the expected outcome of future ASCVD.
BACKGROUND: The number of elderly patients experiencing acute myocardial infarction (AMI) is growing rapidly, and their hospital mortality rate remains high, although mortality after AMI declined in the 1990s with the introduction of new therapeutic modalities. METHODS AND RESULTS: We compared the management, in-hospital complications, and 30-day and 1-year mortality rates in two cohorts of elderly (> or = 75 years of age) AMI patients in the coronary care units in Israel before and after the reperfusion era. The first cohort of 789 consecutive patients was from the Secondary Prevention Reinfarction Israel Nifedipine Trial registry in 1981-1983; the second 366 patients came from two prospective nationwide surveys in 1992 and 1994. Reperfusion therapies were not used in 1981-1983 but were used in 1992-1994. The 30-day mortality rate declined from 38% in 1981-1983 to 27% in 1992-1994 (odds ratio, 0.49; 95% confidence interval [CI], 0.34 to 0.71), and the cumulative 1-year mortality rate declined from 52% to 38% (hazard ratio [HR], 0.62; 95% CI, 0.50 to 0.76). In the 1992-1994 cohort, the decline in mortality was most marked in patients reperfused by thrombolysis and/or percutaneous transluminal coronary angioplasty or coronary artery bypass graft surgery but was also evident in nonreperfused patients: cumulative 1-year mortality rate was 29% in the former (HR, 0.45; 95% CI, 0.31 to 0.67) and 42% in the latter (HR, 0.60; 95% CI, 0.46 to 0.78). CONCLUSIONS: During the last decade, elderly (> or = 75 years) AMI patients experienced fewer in-hospital complications and lower 30-day and 1-year mortality rates, which declined approximately 30%, most markedly in reperfused patients. The favorable outcome in 1992-1994 was related to changes in patient management. Reperfusion therapy is therefore also advocated in elderly AMI patients, unless specific contraindications are present.
OBJECTIVE: Behçet's disease (BD) is a vasculitis mainly observed in young adult males. Juvenile BD is rare and only small series of pediatric cases have been reported. The objective of this study was to define the epidemiology and clinical features of BD among Israeli children. METHODS: A questionnaire was sent to 8 pediatric rheumatology units in Israel and 30 cases of BD diagnosed before the age of 16 years were identified. RESULTS: Fifteen patients fulfilled the International Study Group Criteria for BD, while 15 had an incomplete form of BD. Among the patients with complete BD, stomatitis and skin involvement were the most common manifestations. Other symptoms included genital ulcers, uveitis, CNS involvement, arthritis, and gastrointestinal involvement. A positive family history was elicited in 3 patients. HLA B5 was found in 7 of 12 patients (58%). The 15 patients with incomplete BD all had recurrent stomatitis; other manifestations included uveitis, arthritis, and genital ulcers. HLA B5 was found in 94% of this group. CONCLUSION: Juvenile BD in Israel is not uncommon, and is frequently associated with HLA B5 positivity. This could indicate a genetic susceptibility in our region. Half of the patients in our series had an incomplete form of BD, which may represent a less severe variant of the disease. In any case, careful follow-up is required, since their condition could eventually evolve into complete BD.
The use of lead in petrol in Israel is described. Results of a soil survey are presented and the distribution of lead in soil, water, air, edible plants and the human organism is reviewed. Soils do not generally show high lead retention. The concentrations of lead in water, air and edible plants are low as is the concentration of lead in blood. A possible source of danger is the use of spent motor oil as a fuel in glass making furnaces.
An NDV strain was isolated in Israel from a starling suffering from severe neurological affections. The strain appeared to be lentogenic to chickens, its hemagglutinin being thermostable and active toward horse erythrocytes. Comparative studies including LaSota and B1 NDV reference strains showed that the isolate is not a vaccinal strain used for vaccination in the country.
BACKGROUND: Vibrio vulnificus is a gram-negative bacterium that causes septicaemia and wound infection. Cases occur sporadically, and no previous outbreaks due to a common source or a clonal strain have been reported. In the summer and autumn of 1996 and 1997, an outbreak of invasive V. vulnificus infection occurred in Israel in people who had recently handled fresh, whole fish purchased from artificial fish-ponds. METHODS: We reviewed clinical and epidemiological information, and undertook an environmental investigation to assess disease characteristics, modes of transmission, phenotypic characteristics of the bacterium, and fish-marketing policy. The clonal nature of 19 isolates was studied by biotyping, pulsed-field gel electrophoresis, and restriction-fragment length polymorphism (RFLP) analysis of a PCR fragment. FINDINGS: During 1996-97, 62 cases of wound infection and bacteraemia occurred. 57 patients developed cellulitis, four had necrotising fasciitis, and one developed osteomyelitis. In all cases, the fish were cultivated in inland fish-ponds. In the summer of 1996, fish-pond managers initiated a new marketing policy, in which fish were sold alive instead of being packed in ice. Phenotypically, the isolates had five atypical biochemical test results. The isolates were non-typeable by pulsed-field gel electrophoresis, and all had the same PCR-RFLP pattern which had not been seen previously. INTERPRETATION: The cause of the outbreak was a new strain of V. vulnificus, classified as biogroup 3. A new fish-marketing policy that began in 1996 may have exposed susceptible people to the organism.
A cohort of 243 HIV-seropositive Ethiopian immigrants has been studied clinically and immunologically since their arrival in Israel in May 1991. The prevalence of HIV infection in this Ethiopian community is 1.74%, with a male to female ratio of 1.3:1. The median age is 30 years; women are somewhat younger (median 29) than men (median 33). The prevalence of HIV infection among Ethiopian immigrants is similar to the estimated rate found in the general population in Ethiopia (1.85%). Blood median counts of CD4 positive and CD8 positive T cells on first determination were 391 and 878 x 10(6)/l respectively. The number of HIV carriers with CD4 levels below 300 and 200 x 10(6)/l in a subcohort of 172 individuals was 52 (30.2%) and 26 (15.1%), respectively. The vast majority (> 90%) of the cohort are still clinically asymptomatic. This, and the fact that immigrants tested prior to 1991 were all HIV negative, attest to the recent introduction of HIV infection into this population. In spite of the recency of HIV infection, CD4 counts were relatively low in a high proportion of infected individuals.
BACKGROUND: Investigation of observed differences in outcomes among medical centers is of major interest to the medical community and the public and has a substantial impact on efforts to improve the quality of medical care. METHODS: This study analyzed data from consecutive patients who underwent isolated coronary artery bypass grafting at 14 medical centers. Data included demographic and clinical information, comorbidity, cardiac catheterization results, and 30-day postoperative vitality status. Logistic regression analysis was used to identify variables associated with mortality. An outlier hospital was defined as one having an observed mortality outside the 95% confidence interval boundaries around the expected mortality rate calculated, given the patient risk factors. RESULTS: The overall crude 30-day mortality rate for isolated coronary artery bypass grafting among the 4,835 patients in this study was 3.1%. The rate varied among centers, ranging from 0.85% to 7.05%. Predictors of 30-day mortality included advanced age, female sex, diabetes mellitus, poor left ventricular function, high creatinine level, high priority of operation, and three-vessel disease (with or without left main coronary artery disease). After adjustment for risk factors, two hospitals were defined as outliers. CONCLUSIONS: The observed disparity in early mortality among patients undergoing coronary artery bypass grafting is not due solely to differences in case mix.
