RESUMEN
BACKGROUND: Approximately 5.1 million Israelis had been fully immunized against coronavirus disease 2019 (Covid-19) after receiving two doses of the BNT162b2 messenger RNA vaccine (Pfizer-BioNTech) by May 31, 2021. After early reports of myocarditis during adverse events monitoring, the Israeli Ministry of Health initiated active surveillance. METHODS: We retrospectively reviewed data obtained from December 20, 2020, to May 31, 2021, regarding all cases of myocarditis and categorized the information using the Brighton Collaboration definition. We analyzed the occurrence of myocarditis by computing the risk difference for the comparison of the incidence after the first and second vaccine doses (21 days apart); by calculating the standardized incidence ratio of the observed-to-expected incidence within 21 days after the first dose and 30 days after the second dose, independent of certainty of diagnosis; and by calculating the rate ratio 30 days after the second dose as compared with unvaccinated persons. RESULTS: Among 304 persons with symptoms of myocarditis, 21 had received an alternative diagnosis. Of the remaining 283 cases, 142 occurred after receipt of the BNT162b2 vaccine; of these cases, 136 diagnoses were definitive or probable. The clinical presentation was judged to be mild in 129 recipients (95%); one fulminant case was fatal. The overall risk difference between the first and second doses was 1.76 per 100,000 persons (95% confidence interval [CI], 1.33 to 2.19), with the largest difference among male recipients between the ages of 16 and 19 years (difference, 13.73 per 100,000 persons; 95% CI, 8.11 to 19.46). As compared with the expected incidence based on historical data, the standardized incidence ratio was 5.34 (95% CI, 4.48 to 6.40) and was highest after the second dose in male recipients between the ages of 16 and 19 years (13.60; 95% CI, 9.30 to 19.20). The rate ratio 30 days after the second vaccine dose in fully vaccinated recipients, as compared with unvaccinated persons, was 2.35 (95% CI, 1.10 to 5.02); the rate ratio was again highest in male recipients between the ages of 16 and 19 years (8.96; 95% CI, 4.50 to 17.83), with a ratio of 1 in 6637. CONCLUSIONS: The incidence of myocarditis, although low, increased after the receipt of the BNT162b2 vaccine, particularly after the second dose among young male recipients. The clinical presentation of myocarditis after vaccination was usually mild.

Disasters or hazardous incidents, either natural or man-made, continue to increase in frequency and affect more and more citizens of the world community. Many of these are published in the medical literature, each being a "case report" of a single event. In clinical medicine, a common nomenclature and uniform reporting of data enables the collection of similar cases to series studies, with clinical conclusions being drawn. Such a platform is lacking in the field of disaster medicine, impairing the ability to learn from past experiences. In the Medical Department of the Israeli Home Front Command, we coordinate the operation of various medical units and forces in a wide array of events. By doing so, we collect and analyze the relevant data related to disaster management, various components of the medical response, interactions between different components, and the ensuing results. We developed a systematic method of analyzing and describing disaster management issues in various events-DISAST-CIR-Disastrous Incidents Systematic AnalysiS Through Components, Interactions, Results. In this article, we describe this method by presenting the components, interactions, and results of a large-scale train accident that resulted in 270 casualties, 35 of whom were evacuated by helicopters from the accident site. Casualties were distributed among 10 different hospitals. The death toll was 7 people, 5 of whom died at the scene and 2 who died in hospitals. We recommend this method as a standard for scientific reporting of hazardous incidents. Accumulation of data, reported in a similar standardized fashion, would enable comparison and reporting of series, improving our understanding regarding the optimal medical response to various events.

INTRODUCTION: Terrorist attacks have occurred in Tel-Aviv that have caused mass-casualties. The objective of this study was to draw lessons from the medical response to an event that occurred on 19 January 2006, near the central bus station, Tel-Aviv, Israel. The lessons pertain to the management of primary triage, evacuation priorities, and rapid primary distribution between adjacent hospitals and the operational mode of the participating hospitals during the event. METHODS: Data were collected in formal debriefings both during and after the event. Data were analyzed to learn about medical response components, interactions, and main outcomes. The event is described according to Disastrous Incidents Systematic AnalysiS Through-Components, Interactions and Results (DISAST-CIR) methodology. RESULTS: A total of 38 wounded were evacuated from the scene, including one severely injured, two moderately injured, and 35 mildly injured. The severe casualty was the first to be evacuated 14 minutes after the explosion. All of the casualties were evacuated from the scene within 29 minutes. Patients were distributed between three adjacent hospitals including one non-Level-1 Trauma Center that received mild casualties. Twenty were evacuated to the nearby, Level-1 Sourasky Medical Center, including the only severely injured patient. Nine mildly injured patients were evacuated to the Sheba Medical Center and nine to Wolfson Hospital, a non-Level-1 Trauma Center hospital. All the receiving hospitals were operated according to the mass-casualty incident doctrine. CONCLUSIONS: When a mass-casualty incident occurs in the vicinity of more than one hospital, primary triage, evacuation priority decision-making, and rapid distribution of casualties between all of the adjacent hospitals enables efficient and effective containment of the event.

INTRODUCTION: Mass-casualty incidents (MCIs) can occur outside of major metropolitan areas. In such circumstances, the nearest hospital seldom is a Level-1 Trauma Center. Moreover, emergency medical services (EMS) capabilities in such areas tend to be limited, which may compromise prehospital care and evacuation speed. The objective of this study was to extract lessons learned from the medical response to a terrorist event that occurred in the marketplace of a small Israeli town on 26 October 2005. The lessons pertain to the management of primary and secondary evacuation and the operational practices by the only hospital in the town, which is designated as a Level-2 Trauma Center. METHODS: Data were collected during the event by Home Front Command Medical Department personnel. After the event, formal and informal debriefings were conducted with EMS personnel, the hospitals involved, and the Ministry of Health. The medical response components, interactions (mainly primary triage and secondary distribution), and the principal outcomes were analyzed. The event is described according to Disastrous Incidents Systematic Analysis Through Components, Interactions, Results (DISAST-CIR) methodology. RESULTS: The suicide bomber and four victims died at the scene, and two severely injured patients later died in the hospital. A total of 58 wounded persons were evacuated, including eight severely injured, two moderately injured, and 48 mildly injured. Forty-nine of the wounded arrived to the nearby Hillel Yafe Hospital, including all eight of the severely injured victims, the two moderately injured, and 39 of the mildly injured. Most of the mildly injured victims were evacuated in private cars by bystanders. Five other area hospitals were alerted, three of which primarily received the mildly injured victims. Two distant, Level-1 Trauma Centers also were alerted; each received one severely injured patient from Hillel Yafe Hospital during the secondary distribution process. Emergency medical services personnel were able to treat and evacuate all severely and moderately injured patients within 17 minutes of the explosion. A total of 12 of the 21 ambulances arriving on-scene within the first 20 minutes were staffed by EMS volunteers or off-duty workers. CONCLUSION: When a MCI occurs in a small town that is in the vicinity of a Level-2 Trauma Center, and located a > 40 minute drive from Level-1 Trauma Centers, the Level-2 Trauma Center is a critical component in medical management of the event. All severely and moderately injured patients initially should be evacuated to the Level-2 Trauma Center, and given advanced, hospital-based resuscitation. The patients needing care beyond the capabilities of this facility should be distributed secondarily to Level-1 Trauma Centers. To alleviate the burden placed on the local hospital, some of the mildly injured victims can be evacuated primarily to more distant hospitals. The ability to control the flow of mildly injured patients is limited by the large percentage of them arriving by private cars. The availability of EMS in small towns can be augmented significantly by enrolling off-duty EMS workers and volunteers to the rescue effort. Level-2 hospitals in small towns should be prepared and drilled to operate in a "selective evacuation" mode during MCIs.

INTRODUCTION: A mass-casualty incident (MCI) can occur in the periphery of a densely populated area, away from a metropolitan area. In such circumstances, the medical management of the casualties is expected to be difficult because the nearest hospital and the emergency medical services (EMS), only can offer limited resources. When coping with these types of events (i.e., limited medical capability in the nearby medical facilities), a quick response time and rational triage can have a great impact on the outcome of the victims. The objective of this study was to identify the lessons learned from the medical response to a terrorist attack that occurred on 05 December 2005, in Netanya, a small Israeli city. METHODS: Data were collected during and after the event from formal debriefings and from patient files. The data were processed using descriptive statistics and compared to those from previous events. The event is described according to Disastrous Incidents Systematic Analysis Through Components, Interactions, Results (DISAST-CIR) methodology. RESULTS: Four victims and the terrorist died as a result of this suicide bombing. A total of 131 patients were evacuated (by EMS or self-evacuation) to three nearby hospitals. Due to the proximity of the event to the ambulance dispatch station, the EMS response was quick. The first evacuation took place only three minutes after the explosion. Non-urgent patients were diverted to two close-circle hospitals, allowing the nearest hospital to treat urgent patients and to receive the majority of self-evacuated patients. The nearest hospital continued to receive patients for >6 hours after the explosion, 57 of them (78%) were self-evacuated. CONCLUSION: The distribution of casualties from the scene plays a vital role in the management of a MCI that occurs in the outskirts of a densely populated area. Non-urgent patients should be referred to a hospital close to the scene of the event, but not the closest hospital. The nearest hospital should be prepared to treat urgent casualties, as well as a large number of self-evacuated patients.

INTRODUCTION: Medical systems worldwide are facing the new threat of morbidity associated with the deliberate dispersal of microbiological agents by terrorists. Rapid diagnosis and containment of this type of unannounced attack is based on the knowledge and capabilities of medical staff. In 2004, the knowledge of emergency department physicians of anthrax was tested. The average test score was 58%. Consequently, a national project on bioterrorism preparedness was developed. The aim of this article is to present the project in which medical knowledge was enhanced regarding a variety of bioterrorist threats, including cutaneous and pulmonary anthrax, botulinum, and smallpox. METHODS: In 2005, military physicians and experts on bioterrorism conducted special seminars and lectures for the staff of the hospital emergency department and internal medicine wards. Later, emergency department senior physicians were drilled using one of the scenarios. RESULTS: Twenty-nine lectures and 29 drills were performed in 2005. The average drill score was 81.7%. The average score of physicians who attended the lecture was 86%, while those who did not attend the lectures averaged 78.3% (NS). CONCLUSIONS: Emergency department physicians were found to be highly knowledgeable in nearly all medical and logistical aspects of the response to different bioterrorist threats. Intensive and versatile preparedness modalities, such as lectures, drills, and posters, given to a carefully selected group of clinicians, can increase their knowledge, and hopefully improve their response to a bioterrorist attack.

BACKGROUND: The setting of military ground force operations can be demanding and requires a matched medical assistance plan. A major consideration is the type of medical caregiver that is assigned to the mission. We studied the similarities, differences, advantages, and disadvantages of physicians versus paramedics in this scenario. METHODS: We interviewed 20 ground force physicians, highly experienced in this setting. We summarized their responses and formulated quantitative decision-making tables regarding two sorts of missions: a long-duration mission, far from friendly definitive care, and a short-duration mission, close to friendly hospitals. RESULTS: The major areas in which physicians and paramedics differ, pertinent to a ground force operation are: formal education, on-job training, knowledge base, ability to treat a wide variety of medical conditions, ability to perform manual lifesaving procedures, social and moral impact, availability, physical fitness, combat skills, and cost. Of a maximum score of 100 points, for a long-term mission a physician scores 77.7 points while a paramedic scores 63.6 points. The scores for a short-term mission are 72.7 and 67.9, respectively. DISCUSSION: Physicians and paramedics are distinct groups of medical caregivers and this is also true for the setting of ground force operations. They are not interchangeable. Our data show that a physician has a relative advantage over a paramedic, especially in long-term missions, far from friendly facilities. CONCLUSION: A physician is the first choice for all kinds of military ground force missions while a paramedic can be a reasonable substitute for missions of short duration, close to definitive care.

BACKGROUND: The association between exposure to Isotretinoin, the development of depression and suicide attempts is controversial. OBJECTIVE: To retrospectively assess pattern of utilization of mental health services in the Israeli Defense Forces (IDF) during a 5-year period for all subjects exposed to Isotretinoin in comparison to a control group consisting of army conscripts suffering from psoriasis. All subjects were young adults (18 to 21 years old) in compulsory military service. METHOD: Exposure to Isotretinoin mandates reporting and marking as a coded medical profile in the IDFs' computerized medical record of each conscript and soldier. Medical data, tracked by military medical profiles, were summarized from medical records of all subjects treated by Isotretinion during the years 1999-2003 and for the control group for the same period. Use of mental health services was the a-priori defined primary outcome measure. RESULTS: During the study period 1419 subjects were exposed to Isotretinoin and 1102 suffered from psoriasis. Utilization of mental health services was highest for the index group wherein 17.2% (245/1419) of subjects were evaluated or treated compared to 12.5% in the control group (psoriasis). The inter-group differences were statistically significant; Chi-square=15.9 (df=2), p=0.0003. CONCLUSIONS: We suggest that psychiatric evaluation be regularly undertaken prior to initiation of Isotretinion treatment in young adults at risk, as well as providing follow-up visits during and at completion of treatment.

The most prominent known phenotypic risk factor for the development of melanoma is a large number of common melanocytic naevi. The aims of this study were to determine the prevalence of multiple common naevi in a group of 17-year-olds and to identify possible associated risk factors. The study subjects were approximately 40,000 female and 60,000 male 17-year-old Jewish Israelis presenting to army recruitment centres for compulsory military service during a 1-year period from January 2003 to December 2003. Data were gathered on whole-body naevi count, years of education, place of residence and place of birth of the recruit, his/her parents and paternal grandparents. The count of whole-body naevi was carried out by military physicians. The multiple naevi phenotype was defined by the presence of more than 50 naevi. The prevalence of the phenotype was highest amongst recruits of American origin and lowest amongst those of Asian and African origin (P < 0.0001). The prevalence differed in different population centres, the highest being in the coastal cities of Haifa and Tel Aviv. This pattern corresponded to the geographical distribution of melanoma in Israel. Amongst male conscripts, the phenotype was more common in the better educated group (> or =12 years) than in the poorer educated conscripts (< or = 11 years) (P = 0.051). When adjusted for the factors studied, a significant correlation was found between a high multiple common naevi count and American and European origin and residence in coastal cities, reflecting the complex interplay between endogenous and exogenous factors of melanoma.

STUDY OBJECTIVE: Emergency department (ED) physicians and nurses are considered critical sentinels of a bioterrorist attack. We designed a special hospital drill to test EDs' response to inhalational anthrax and assess the level of preparedness for anthrax bioterrorism. We hypothesized that the occurrence of such a drill in an ED would improve the knowledge of its physicians, even those who had not actually participated in the drill. METHODS: We conducted 23 drills at all Israeli general hospitals' EDs. An actor entered the walk-in triage area, simulating a febrile patient with lower respiratory complaints. A chest radiograph with mediastinal widening, as can be seen in early anthrax disease, was planted in the hospital's imaging results system. Patients were instructed to give additional epidemiologic clues, such as having a few friends with a similar syndrome. Either before or after the drills, we distributed multiple choice tests about diagnosis and management of anthrax to the 115 senior emergency physicians at these hospitals. RESULTS: In 91% of EDs, a decision to admit the patient was made. Sixty-one percent included anthrax in the differential diagnosis and activated the appropriate protocols. Only 43% contacted all relevant officials. Average score on the anthrax tests was 58 (of 100). Physicians who were tested before the drill (in their institution) achieved a mean score of 54.5, whereas those who were tested after their ED had been exercised achieved a mean score of 59.3. CONCLUSION: A national framework of drills on bioterrorism can help estimate and potentially augment national preparedness for bioterrorist threats. It is not, on its own, an effective educational tool. More emphasis should be given to formal accredited continuing medical education programs on bioterrorism, especially for emergency physicians and ED nurses, who will be in the front line of a bioterrorist attack.

A simplified, four-step approach was used to establish a medical management and response plan to mega-terrorism in Israel. The basic steps of this approach are: (1) analysis of a scenario based on past incidents; (2) description of relevant capabilities of the medical system; (3) analysis of gaps between the scenario and the expected response; and (4) development of an operational framework. Analyses of both the scenario and medical abilities led to the recommendation of an evidence-based contingency plan for mega-terrorism. An important lesson learned from the analyses is that a shortage in medical first responders would require the administration of advanced life support (ALS) by paramedics at the scene, along with simultaneous, rapid evacuation of urgent casualties to nearby hospitals by medics practicing basic life support (BLS). Ambulances and helicopters should triage casualties from inner to outer circle hospitals secondarily, preferentially Level-1 trauma centers. In conclusion, this four-step approach based on scenario analysis, mapping of medical capabilities, detection of bottlenecks, and establishment of a unique operational framework, can help other medical systems develop a response plan to mega-terrorist attacks.

INTRODUCTION: A mass toxicological event (MTE) caused by an act of terrorism or an industrial incident can create large numbers of ambulatory casualties suffering from mild intoxication, acute stress reaction (ASR), and exacerbation of chronic diseases or iatrogenic insult (such as atropine overdose). The logistical and medical management of this population may present a challenge in such a scenario. The aim of this article is to describe the concept of the Israeli Home Front Command (HFC) of a "Mild Casualties Center" (MCC) for a chemical scenario, and to analyze the results of two large-scale drills that have been used to evaluate this concept. METHODS: Two large-scale drills were conducted. One MCC drill was located in a school building and the second MCC drill was located in a basketball stadium. These medical centers were staffed by physicians, nurses, and medics, both military (reservists) and civilian (community, non-hospital teams). Two hundred simulated patients entered the MCC during each of the drills, and drill observers assessed how these patients were managed for two hours. RESULTS: Of the casualties, 28 were treated in the "medical treatment site", 10 of which were relocated to a nearby hospital. Only four casualties were treated in the large "mental care site", planned for a much higher burden of "worried well" patients. Documentation of patient data and medical care was sub-optimal. CONCLUSION: A MCC is a logistically suitable solution for the challenge of managing thousands of ambulatory casualties. The knowledge of the medical team must be bolstered, as most are unfamiliar with both nerve gas poisoning and with ASR. Mild casualties centers should not be located within hospitals and must be staffed by non-hospital, medical personnel to achieve the main task of allowing hospital teams to focus on providing medical care to the moderate and severe nerve gas casualties, without the extra burden of caring for thousands of mild casualties.

PURPOSE: To determine the changing prevalence of myopia during the years 1990 through 2002 among the 16- to 22-year age group and identify possible risk factors. METHODS: A retrospective study, based on 13 repeated prevalence surveys conducted over a 13-year period. The study subjects were all Israeli nationals belonging to the 16- to 22-year age group from the years 1990 to 2002. Refraction was determined by using subjective visual acuity followed by noncycloplegic autorefraction and subjective validation based on the autorefraction RESULTS: Mild myopia was defined as a refractive error of -0.50 to -3.00 D in at least one eye, moderate myopia as -3.25 to -6.00 D, and high myopia as more than -6.00 D. results. There were 919,929 subjects (382,139 [42%] females and 537,790 [58%] males) included in the study. The overall prevalence of myopia increased from 20.3% in 1990 to 28.3% in 2002. The prevalence of high, moderate, and mild myopia significantly increased in males from 1.7%, 5.7%, and 11.6% in 1990 to 2.05%, 7.2%, and 16.3% in 2002, respectively (P < 0.001). In females, the prevalence of myopia increased from 1.9%, 6.6%, and 13.5% in 1990 to 2.4%, 9.2%, and 20.7% in 2002, respectively (P < 0.001). A correlation between myopia and the number of years of education was observed. Non-Israeli origin was found to be a significant risk factor for myopia. CONCLUSIONS: During the 13 years from 1990 to 2002, the prevalence of myopia significantly increased among the Israeli population. Although there was an association with the level of education, gender, ethnicity, and origin, the prevalence of myopia increased on an annual basis, independent of these factors.

BACKGROUND: In military basic training, stress fractures are a common orthopedic problem. Female recruits have a significantly higher incidence of stress fractures than do male recruits. Because the Israeli Defense Forces opened traditionally male roles in combat units to female recruits, their high risk for stress fractures is of concern. OBJECTIVE: To compare the prevalence of stress fractures during Israeli Defense Forces anti-aircraft basic training among otherwise healthy young male and female recruits, in terms of anatomic distribution and severity. DESIGN: Ten mixed gender batteries, including 375 male recruits and 138 female recruits, carried out basic training in the Israeli anti-aircraft corps between November 1999 and January 2003. Each battery was monitored prospectively for 10 weeks of a basic training course. During that time, recruits who were suspected of having an overuse injury went through a protocol that included an orthopedic specialist physical examination followed by a radionuclide technetium bone scan, which was assessed by consultant nuclear medicine experts. The assessment included the anatomic site and the severity of the fractures, labeled as either high severity or low severity. RESULTS: Stress fractures were significantly more common among female recruits than among male recruits. A total of 42 male (11.2%) and 33 female (23.91%) recruits had positive bone scans for stress fractures (female:male relative ratio, 2.13; p < 0.001). Pelvic, femur, and tibia fractures were significantly more common among female recruits than among male recruits (p < 0.005). Female recruits had significantly more severe fractures in the tibia (p < 0.05). However, there was no significant difference in the severity of stress fractures in the femur or metatarsals between male and female recruits, as assessed by radionuclide uptake. CONCLUSIONS: We recommend that different training programs be assigned according to gender, in which female recruits would have a lower level of target strain or a more moderate incline of strain in the training program throughout basic training.

BACKGROUND: Respiratory diseases are responsible for a significant proportion of serious morbidity among adolescents. There are few reports on the prevalence of common respiratory disorders in this population. The previous studies focused on specific diseases and screened relatively small samples. OBJECTIVE: To define the prevalence of different common respiratory disorders among 17-year-old Israeli conscripts. DESIGN: All 17-year-old Israeli nationals are obliged by law to appear at the Israel Defense Forces recruiting office for medical examination. Respiratory disease specialists evaluated and classified nominees with suspected respiratory disorders. RESULTS: A high prevalence of respiratory morbidity was found among 94,805 17-year-old conscripts (61.5% male, 39.5% female). The most prevalent diagnosis was asthma (in 8% of male and 6.8% of female subjects). Fifty-five per cent of the asthma patients suffered from moderate to severe disease. The prevalence of chronic obstructive pulmonary disease was 0.03% for the male and 0.01% for the female subjects. A difference in morbidity patterns between male and female adolescents was noted, particularly in the prevalence of chest deformation and spontaneous pneumothorax. CONCLUSIONS: The most prevalent respiratory disorder among 17-year-old Israeli conscripts was asthma. One-half of the asthma patients in this study suffered from moderate to severe disease. The prevalence of other respiratory disorders was much lower.

In April 1999, during the crisis in Kosovo, the Israeli government launched a medical, field hospital in order to provide humanitarian aid to the Albanian refugees that fled from their homes in Kosovo. This facility was set up by the Medical Corps of the Israeli Defense Forces, in a refugee camp located in Northern Macedonia. During the 16 days during which the hospital functioned, the medical staff treated 1,560 patients and hospitalized >100. The field hospital served as a referral center for all of the other primary clinics that were hastily erected in the camp and its surroundings. This communication elaborates on the various aspects of the humanitarian medical aid that were provided by this medical facility and the conclusions that learned from such a mission.

Terrorist attacks can occur in remote areas causing mass-casualty incidents MCIs far away from level-1 trauma centres. This study draws lessons from an MCI pertaining to the management of primary and secondary evacuation and the operational mode practiced. Data was collected from formal debriefings during and after the event, and the medical response, interactions and main outcomes analysed using Disastrous Incidents Systematic Analysis through Components, Interactions and Results (DISAST-CIR) methodology. A total of 112 people were evacuated from the scene-66 to the nearby level 3 Laniado hospital, including the eight critically and severely injured patients. Laniado hospital was instructed to act as an evacuation hospital but the flow of patients ended rapidly and it was decided to admit moderately injured victims. We introduce a novel concept of a 'semi-evacuation hospital'. This mode of operation should be selected for small-scale events in which the evacuation hospital has hospitalization capacity and is not geographically isolated. We suggest that level-3 hospitals in remote areas should be prepared and drilled to work in semi-evacuation mode during MCIs.

Contact dermatitis is one of the leading causes of occupational morbidity and absenteeism and has become an intolerable cause of missed workdays and health problems in the Israeli military. The aim of this study was to determine the rate of contact dermatitis in maintenance and clerical workers, the common allergens causing it, and the background of atopy in the subjects in order to design preventive measures. Medical records of all recruits to the Israel Defense Forces from 2000 to 2003 were reviewed for contact dermatitis. The 102 cases found were further assessed for job assignment, atopic background, and allergens. Of the 102 cases, 60 had irritant contact dermatitis and 42 had allergic contact dermatitis, of which 33 (78.6%) were maintenance workers, mainly mechanics. 13 soldiers in the maintenance job category (39%) and 2 soldiers in the clerical group (22.2%) had atopic background. There were 55 positive reactions in patch tests, 25 of them to oil and cooling fluids, with 14.5% attributed to methylchloroisothiazolinone/methylisothiazolinone) (Kathon CG). Atopy was found to be a risk factor for allergic contact dermatitis in our study and should be screened for in job assignment procedures in the military. Oil and greases contain significant allergens, especially their preservatives.

A number of typologies have been developed in the strategic management literature to categorize strategies that an organization can pursue at the business level. Extensive research has established Porter's generic strategies of (1) cost leadership, (2) differentiation, (3) differentiation focus, (4) cost focus, and (5) stuck-in-the-middle as the dominant paradigm in the literature. The purpose of the current study was to research competitive strategies in the Israeli ambulatory health care system, by comparing managerial perceptions of present and ideal business strategies in two Israeli sick funds. We developed a unique research tool, which reliably examines the gap between the present and ideal status managerial views. We found a relation between the business strategy and performance measures, thus strengthening Porter's original theory about the nonviability of the stuck-in-the-middle strategy, and suggesting the applicability Porter's generic strategies to not-for-profit institutes in an ambulatory health care system.

BACKGROUND: There are only few reports on the prevalence of common cardiovascular disorders among adolescents. The previous studies focused on specific diseases, and screened relatively small samples. OBJECTIVE: The aim of this study was to define the prevalence of different common cardiovascular disorders among 17-year-old Israeli conscripts. A comparison between the morbidity patterns of female and male adolescents was also performed. DESIGN: All 17-years-old Israeli nationals are obliged by law to appear at the Israel Defense Forces Recruiting Office for medical examination except for orthodox religious and Arabic adolescents. Cardiology specialists evaluated and classified nominees with suspected cardiovascular disorders. RESULTS: The most prevalent diagnoses were valvular heart disease (590/ 100,000), syncope (440/100,000), and mitral valve prolapse (340/100,000). The most prominent differences between female and male adolescents were noted in the prevalence of: congenital valvular heart disease, syncope, history of hypertension, supraventricular tachycardia with pre-excitation, myocarditis and pericarditis, and bradycardia and conduction disorders. CONCLUSIONS: The most prevalent cardiac disorders among 17-year-old Israelis were congenital valvular heart disease, syncope and mitral valve prolapse. Some significant differences were noted between the morbidity patterns among male and female adolescents. The higher prevalence of congenital valvular heart disease compared to non-valvular heart disease is surprising. The prevalence of hypertension among Israeli adolescents in the last 15 years remained stable.
