Background: Most Israeli males aged 16–17 undergo a thorough medical examination prior to recruitment into the army. During the last 50 years, extensive data have been gathered enabling a study of time trends in the prevalence of common diseases in this age group.

Objectives: To examine the current prevalence of common diseases, compare the results with those of previous cohorts, and assess the influence of the massive immigration during the 1990s.         

Methods: The health examination at the recruitment centers includes a medical history, complete physical examination, and review of medical documentation provided by the family physician. If needed, additional tests and referral to specialists are ordered. The prevalence of selected diseases and severity was drawn from the computerized database of the classification board. Two cohorts, 1992–94 and 2003–04, were examined and compared with three previous cohort studies in 1957–61, 1977–78 and 1982–84. Data were stratified according to origin and country of birth.

Results: The prevalence of asthma increased dramatically during the years from 10.2 per 1000 examinees in 1957–61 to 111.6 per 1000 examinees in 2003–04. The prevalence of tuberculosis declined and then increased from 0.6 per 1000 adolescents in 1982–84 to 2.4 per 1000 adolescents in 2003–04. The prevalence of type 1 diabetes mellitus increased from 0.2 cases per 1000 examinees in 1957–61 to 0.8 cases in 1977–78 and 1982–84 and 0.9 cases per 1000 examinees in 2003–04. The prevalence of severe heart defects and severe epilepsy declined in the last 20 years (1.4 and 1.7 cases per 1000 examinees in the 1982–84 cohort to 0.4 and 0.3 cases per 1000 examinees in the 2003–4 cohort respectively). The patterns of disease prevalence were different for immigrants: tuberculosis was more common while asthma and allergic rhinitis were less prevalent.

Conclusions: The prevalence of common diseases among adolescents in Israel has changed over the last 50 years. There is a different pattern for immigrants and for those born in Israel.

Eponyms are titles of medical disorders named for individuals who originally described the condition. They also help us remember and identify the disorder. Medicine is replete with them, and changing them or eradicating them, for whatever reason, is not simple. But when there is a moral issue involved – for example, the research conducted under overwhelming unethical conditions – we believe it wrong to perpetuate and thus “reward” the memory of the individual for whom the disorder is named. The name of a syndrome should thus be discontinued if described by an individual whose research used extreme or who was involved in atrocities against humanity. Ethical considerations should be introduced into medical nosology just as they exist in patient care and research. This article details a group of notable eponyms, the names of which are associated with overt crimes of the medical community during the Nazi era, and provides alternative medical nomenclature. In addition, examples are provided of eponyms named after Nazi era victims, eponyms of those who protested such injustices, and eponyms of those who had to flee discrimination and death. These should be remembered and even strengthened, as opposed to those of the perpetrators, which should be obliterated. Since the greatest accolade a physician can earn is praise from his colleagues as expressed in an eponym entrenched in one's name, the medical profession should remove any honor given to physicians involved in crimes to humanity.

Background: Drug-induced thyrotoxicosis is not uncommon. It may worsen life-threatening arrhythmias and may be refractory to medical treatment. Near-total thyroidectomy presents a valid alternative to medical therapy and should be considered early in the management of the disease.

Objectives: To assess whether near-total thyroidectomy was a viable approach for our patients.

Methods: Twelve patients – 7 men and 5 women, aged 63 to 82 years – presented with drug-induced fulminant thyrotoxicosis following 1 to 12 months of amiodarone treatment (11 patients, mean 7 months) and after a 6 months course of interferon-alpha treatment (one patient). Medical therapy included propylthiouracil in doses up to 1200 mg/day in all patients and a beta-receptor antagonist in seven. Five patients had to stop amiodarone treatment and start high doses of steroids. A thyroid scan was performed in all patients using 5 mCi of Tc-99m pertechnetate. The thyroid scan showed absent uptake of the tracer in the thyroid bed in all patients, precluding the use of radioablation.

Results: Four patients (three with AIT[1] and one with interferon therapy) who did not respond to 3 months of medical therapy required surgical thyroidectomy due to severe unremitting thyrotoxicosis. A near-total thyroidectomy resulted in rapid correction of thyrotoxicosis, enabling continuation of the anti-arrhythmic drug. There were no intraoperative or postoperative arrhythmias. Subsequently, all patients recovered rapidly and remained well and euthyroid on thyroxine replacement therapy.

Conclusions: Since surgery results in rapid control of thyrotoxicosis and permits continued therapy with amiodarone, we suggest that near-total thyroidectomy warrants consideration as a definitive treatment for resistant amiodarone or interferon-induced thyrotoxicosis.

Background: In 2003 a total of 43 soldiers in the Israel Defense Forces committed suicide; only 20% of them were known to the IDF[1] mental health services. Somatic symptoms are often the only presentation of emotional distress during the primary care visit and may be the key to early identification and treatment.

Objectives: To examine whether the information in the medical records of soldiers can be used to identify those suffering from anxiety, affective or somatoform disorder.

Methods: We conducted a case-control study using the information in the electronic medical records of soldiers who during their 3 year service developed affective disorder, anxiety, or somatoform disorder. A control group was matched for recruitment date, type of unit and occupation in the service, and the Performance Prediction Score. The number and reasons for physician visits were collated.

Results: The files of 285 soldiers were examined: 155 cases and 130 controls. The numbers of visits (mean SD) during the 3 and 6 month periods in the case and control groups were 4.7 ± 3.3 and 7.1 ± 5.0, and 4.1 ± 2.9 and 5.9 ± 4.6 respectively. The difference was statistically significant only for the 6 month period (P < 0.05). The variables that remained significant, after stepwise multivariate regression were the Performance Prediction Score and the presenting complaints of back pain and diarrhea.

Conclusions: These findings may spur the development of a computer-generated warning for the primary care physician who will then be able to interview his or her patient appropriately and identify mental distress earlier. 

Background: Syndromic surveillance systems have been developed for early detection of bioterrorist attacks, but few validation studies exist for these systems and their efficacy has been questioned.

Objectives: To assess the capabilities of a syndromic surveillance system based on community clinics in conjunction with the WSARE[1] algorithm in identifying early signals of a localized unusual influenza outbreak.

Methods: This retrospective study used data on a documented influenza B outbreak in an elementary school in central Israel. The WSARE algorithm for anomalous pattern detection was applied to individual records of daily patient visits to clinics of one of the four health management organizations in the country.

Results: Two successive significant anomalies were detected in the HMO’s[2] data set that could signal the influenza outbreak. If data were available for analysis in real time, the first anomaly could be detected on day 3 of the outbreak, 1 day after the school principal reported the outbreak to the public health authorities.

Conclusions: Early detection is difficult in this type of fast-developing institutionalized outbreak. However, the information derived from WSARE could help define the outbreak in terms of time, place and the population at risk.

Background: The association between antibiotic use in the community and antimicrobial resistance is known. Attention has recently focused on the type of agents being prescribed.

Objectives: To implement, evaluate and compare the efficacy of two community interventions programs – continuous versus seasonal medical education – oriented to primary care physicians with emphasis on appropriate use of antimicrobial drugs.

Methods: From October 2000 to April 2003 we conducted two interventions: a) a monthly educational campaign in selected clinics promoting appropriate diagnosis of common infectious diseases and prudent antibiotic use (continuous intervention group); and b) a massive educational campaign, conducted before two consecutive winters, promoting the judicious use of antibiotics for treating respiratory infections (continuous intervention group and seasonal intervention group). Sixteen similar clinics were randomized (8 to each group). The total antibiotic use was measured as defined daily dose/1000 patients/day, and compared between the groups. 

Results: The total use of antibiotics decreased between 1999-2000 and 2002-2003 in both groups, but slightly more significantly in the continuous intervention group. The DDD/1000 patients/day for the seasonal group in 1999-2000 was 27.8 vs. 23.2 in 2002-2003; and for the continuous group 28.7 in 1999-2000 vs. 22.9 in 2002-2003, a reduction of 16.5% and 20.0% respectively (p<0.0001). The main change in antibiotic use was noted for broad-spectrum antibiotics.

Conclusions: We present a successful community intervention program aimed to reduce unnecessary antibiotic use. Amplification of this type of intervention is imperative to stop the increase in antimicrobial resistance.
 

Background: Halofuginone is a novel antifibrotic agent that can reserve the fibrotic process by specific inhibition of collagen type I synthesis.

Objectives: To evaluate the effect of Halo on the development of glomerulosclerosis and interstitial fibrosis in the 5/ 6 nephrectomy rat model.

Methods: Male Wistar rats were assigned to undergo 5/6 NX or sham operation, and then divided into three groups: 5/6 NX rats (NX-Halo and NX-Control) and sham. Systolic blood pressure proteinuria and body weight were determined every 2 weeks. At sacrifice (10 weeks) creatinine clearance was evaluated and remnant kidneys removed for histologic examination, Sirius red staining and in situ hybridization.

Results: Systolic blood pressure increased progressively in both 5/6 NX groups. Halo slowed the increase in proteinuria in 5/6 NX rats. As expected, creatinine clearance was lower in 5/6 NX groups when compared to sham rats. Creatinine clearance was significantly higher in the NX-Halo group at the end of the study period. Histologic examination by light microscopy showed significantly less severe interstitial fibrosis and glomerulosclerosis in Halo-treated rats. The increase in collagen α1 (I) gene expression and collagen staining after nephrectomy was almost completely abolished by Halo.

Conclusions: Halofuginone reduced proteinuria as well as the severity of interstitial fibrosis and glomerulosclerosis in 5/6 NX rats. The renal beneficial effect of Halo was also demonstrated by the blunted decrease in creatinine clearance observed in the treated animals.  
 

Objectives: To evaluate immunologic parameters in B-CLL[1] associated with autoimmune disorders. As a hypothesis we postulated that in those cases, the malignant B cells might disclose an activated phenotype pattern leading to the production of autoantibodies.

Methods: In the Registry of the Israel Study Group on CLL that includes 964 patients, we found 115 cases showing a single or a complex of autoimmune disorders. We evaluated the lymphocyte morphology, immunoglobulin G and beta-2-microglobulin serum levels and positivity of the CD38 and FMC7 markers, and compared these values with those of a matched CLL population without autoimmune disorder. 

Results: The main autoimmune disorders encountered were autoimmune hemolytic anemia (55 patients), Evan's syndrome (n=7), Hashimoto's thyroiditis (n=15), vasculitis (n=5) and rheumatoid arthritis (n=4). We found atypical prolymphocytic morphology in 22%, high expression of the activation antigens CD38 and/or FMC7 in 30%, and high level of immunoglobulin G (> 1000 mg/dl) and beta-2-microglobulin in 57% and 78% respectively. When compared with a matched CLL population without an autoimmune disorder, these values were statistically significant.

Conclusions: Our data, which show activated lymphocyte morphology, high levels of IgG[2] and beta-2-microglobulin, and increased expression of CD38 and/or FMC7 in a significant number of cases, suggest that some degree of activation of B cells may lead to the occurrence of an autoimmune disorder in CLL.
