Background: Little information is available on the clinical practice and implementation of guidelines in treating acute myocardial infarction patients in Israel.

Objective: To assess patient characteristics, hospital course, management, and 30 day clinical outcome of all AMI[1] patients hospitalized in Israel during a 2 month period in 2000.

Method: We conducted a prospective 2 month survey of consecutive AMI patients admitted to 82 of 96 internal medicine departments and all 26 cardiac departments operating in Israel in 2000. Data were collected uniformly by means of a hospital and 30 day follow-up form.

Results: During the survey 1,683 consecutive patients with a discharge diagnosis of AMI were included. Their mean age was 66 years; 73% were male. The electrocardiographic pattern on admission revealed ST elevation, non-ST elevation and an undetermined ECG[2] in 63%, 34% and 4% of patients respectively. Aspirin and heparin were given to 95% of patients. Beta-blockers and angiotensin-converting enzyme inhibitors were given to 76% and 65% of patients respectively. Among hospital survivors, 45% received lipid-lowering drugs. Thrombolytic therapy was administered in 28% of patients, coronary angiography was used in 45%, and 7% of patients underwent primary percutaneous coronary intervention. The 7 and 30 day mortality rates were 7% and 11% respectively.

Conclusions: This nationwide survey shows that one-third of the AMI patients in Israel are elderly (≥ 75 years). The survey suggests that clinical guidelines for the management of patients with AMI are partially implemented in the community. Data from large surveys representing the "real world" practice are of utmost importance for the evaluation of clinical guidelines, research and educational purposes.

Background: Human parvovirus B19 is responsible for a variety of clinical syndromes, such as erythema infectiosum, non-immune hydrops fetalis, transient aplastic anemia, and arthropathies. HPV is also suspected of playing a role in the pathogenesis of various chronic inflammatory and autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, Kawasaki disease and multiple sclerosis.

Objectives: To study the age distribution and clinical presentation of patients hospitalized for human parvovirus B19 infection.

Method: We reviewed the case records of all pediatric patients with serologic evidence of HPV infection who were admitted during a 20 month period to a major community hospital

Results: Of 128 children tested for HPV, 48 had evidence of acute infection based on the presence of immunoglobulin M antibodies; 8 patients who also had positive IgM for other viruses were excluded, thus 40 case records were studied. The mean age of the patients was 5.21 years, but 22 patients were under 4: The clinical presentations included 25 patients with fever, either recurrent or prolonged, accompanied in some by enlarged spleen, liver and lymph nodes, skin rash and arthropathy; the remaining patients were investigated for anemia, skin rash, joint complaints and hepatitis. In addition; HPV infection was documented in several well-defihed clinical conditions, such as SLE, vasculitic skin lesions, acute lymphoblastic leukemia, pure red cell aplasia, and optic neuritis.

Conclusions: In a group of 40 pediatric patients exhibiting anti-HPV IgM antibodies, a younger age and less common clinical presentations were observed, furthermore 5 patients had clinical syndromes in which the causative role of HPV infection was not clear.

Background: Acute renal infarction is an oft-missed diagnosis. As a result; its true incidence, although presumed to be low, is actually unknown. Surprisingly, the medical literature on the subject, other than anecdotal case reports, is scarce.

Objectives: To increase physician awareness of the diagnosis and to identify predictive clinical and laboratory features of the entity.

Method: Between 1 November 1997 and 31 October 2000, 11 cases of acute renal infarction in 10 patients were diagnosed in our center by contrast-enhanced computerized tomography. The medical charts of these patients were reviewed regarding risk factor, clinical presentation, possible predictive laboratory examinations, and out-come.

Results: During the 36 month observation period, the incidence of acute renal infarction was 0.007%. The mean age of the patients (5 men and 5 women) was 67.4 + 21.1 (range 30-87 years). In four cases the right and in five the left kidney was involved; in the other. two cases bilateral:involvement was seen. In 7/10 patients, an increased risk for thromboembolic events was found. Six had chronic atrial fibrillation and one had a combined activated protein C resistance and protein S deficiency, Three patients had suffered a previous thromboembolic event. Two cases were receiving anticoagulant therapy with an INR of 1.6 and 1.8, respectively. On admission, flank pain was recorded in 10/11, fever in 5 and nausea/vomiting in 4 cases. Hematuria was detected in urine reagent strips in all cases; Serum lactate dehydrogenase and white blood cell count were elevated in all cases (1,570 + 703 IU/L and 12,988 + 3,841/ l, respectively). In no case was the diagnosis of acute renal infarction  initially entertained. The working diagnoses were .renal colic in 2 pyelonephritis in 3, renal carcinoma, digitails intoxication, and suspected endocarditis in one patient each, and an acute abdomen in 3. Time from admission to definitive CT diagnosis ranged from 24 hours to 6 days; Three patients were treated with intravenous heparin and another with a combination of IV heparin and renal intra-arterial urokinase infusion with, in the latter case, no recovery of function of the affected kidney. With the exception of this one patient (with a contralateral contracted kidney) who required maintenance dialysis, in all other cases serum creatinine levels. remained unchanged or reverted to the baseline mean of 1.1 mg/dl (0.9-1.2).

Conclusions: Acute renal infarction is not as rare as previously assumed. The entity is often misdiagnosed. Unilateral flank pain in a patient with an increased risk for thromboembolism should raise the suspicion of renal infarction. In such a setting, hematuria, leuaocytosis and an elevated LDH level are strongly supportive of the diagnosis.

Background: Head louse infestations are prevalent worldwide. Over the past 20-25 years, 15-20% of all children in Israel between 4 and 13 years of age have been infested with head lice; This is mainly due to the existence of ineffective pediculicides on the market.

Objective: To examine the pediculicidal efficacy and safety of a natural remedy (”Chick-Chack") and to compare it in an open clinical study with a known pesticide spray.

Methods: The natural remedy, which contains coconut oil, anise ail and ylang ylang oil:, was applied to the hair of infested.children three times at 5 day intervals. Each treatment lasted for 15 minutes. The control pediculicide was a spray, formulation containing permethrin, malathion, piperonyl butoxide, isododecane and propellant gas, which was applied twice for 10 minutes with a 10 day interva1 between applications.

Results: Of 940 Children, aged 6-14 years, from six schools in Jerusalem who were examined for head louse infestastion,199 (21:.2÷/) were infested with lice and eggs, while 164 (17.4% ) were infested only  with nits. Altogether, 119 children were randomly treated with either the natural remedy or the control product. Treatment was successful with the natural remedy  in 60 children (92.3%) and with the control pediculicide in 59 children (92.2%). There were no significant side effects associated with either formulation.

Conclusions: The natural remedy was very effective in controlling  louse infestations under clinical conditions and caused no serious side effects.
 

Background: The prevalence of clinical manifestations and laboratory parameters in systemic lupus erythematosus differ among various ethnic groups. Few studies have reported on SLE[1] in Arabs.

Objectives: To summarize the demographic, clinical and laboratory features of Arab SLE patients and to compare them with other series from different Arab countries.

Methods: We reviewed the charts of all Arab SLE patients who had been seen at the Carmel Medical Center in Haifa, the Nazareth Hospital and the Holy Family Hospital in Nazareth, and a professional clinic (a referral outpatient clinic of the largest health maintenance organization in Israel) in Acre – all cities in northern Israel. Only patients with symptoms of more than one year were included. Demographic, clinical and laboratory parameters were documented and compared with those of four series from different Arab countries.

Results: The study group comprised 34 patients. The majority of the patients was Moslem; there were a few Druze and one Christian. There was no statistical difference between our patients and any of the other Arab series in terms of arthritis, neuropsychiatric manifestations and VDRL. The presence of serositis and mucocutaneous manifestations was significantly lower in our series compared to some of the other series. However, there was significantly less renal involvement in our patients compared to each of the other series.

Conclusions: The prevalence of most clinical and laboratory parameters in Israeli Arab SLE patients is comparable to that of other series of SLE patients from different Arab countries. The prevalence of renal involvement in Israeli Arab SLE patients seems to be lower than in SLE patients from different Arab countries.

The chemical warfare agent sulfur mustard affects primarily the eyes, skin and respiratory tract. Of these, ocular injury is the most immediate and distressing. Learning to recognize ocular injury enables the treating physician to provide early and suitable treatment, which will reduce complications and allow the victim a rapid recovery.

Background: Small bowel diverticula are usually asymptomatic and rare. Their importance is based on the fact that they carry the risk of serious complications.

Objective: To study the implications and the therapeutic approach regarding small bowel diverticulosis.

Methods: The medical records of 54 patients with diverticular disease of the small bowel, including Meckel’s and duodenum diverticula, were retrospectively reviewed. The mean age of the 32 male and 22 female patients was 53.2 years.

Results: Diverticula were found in the duodenum in 11 cases, in the jejunum and ileum in 21 cases, and with Meckel’s diverticula in 22 cases. In 24% of the patients the diverticula were multiple. The most common clinical symptom was abdominal pain, in 44.4%. Most of the duodenum diverticula were asymptomatic; 47.6% of the patients with diverticular disease located in the jejunum and ileum presented with chronic symptoms. The overall diagnostic rate for symptomatic diverticula before surgery was 52.7%; in 33.3% diverticula were found incidentally during other diagnostic or therapeutic procedures. Forty-one patients were managed surgically: 15 patients were operated on urgently because of infection or rupture, 4 patients for bleeding, 5 patients for intestinal obstruction and one patient for jaundice.

Conclusions: The incidence of asymptomatic small bowel diverticula is difficult to ascertain. Patients with Meckel’s and duodenal diverticula are usually asymptomatic, while the majority of jejunal and ileal diverticula patients present with chronic symptoms. The preoperative diagnostic rate is higher for duodenal diverticula. Small bowel diverticula do not require surgical treatment unless refractory symptoms or complications occur.

Background: Lithium has been a part of the psychiatric pharmacopoeia for more than half a century. Its efficacy is marred by a narrow therapeutic index and significant toxicity.

Objectives: To increase physicians’ awareness of the various manifestations of lithium intoxication.

Methods: We reviewed the clinical data of cases of lithium poisoning occurring in a municipal hospital during a 10 year period.

Results: Eight patient records were located. The mortality rate was 12.5%. All patients were women and the mean age was 66.4 years. The most common symptoms were neurological. One illustrative case is described in detail with lithium serum levels showing the usual two-phase decline.

Conclusions: Lithium poisoning can present in many forms. Increased physician awareness and the early use of effective treatment, mainly hemodialysis, will prevent mortality and protracted morbidity associated with this condition.
 

Background: The importance of health promotion and disease prevention in health policy and clinical practice is widely accepted in many countries. However, a large number of medical schools do not dedicate a significant part of their curriculum to these aspects. In Israel, there are no reports on the training of the future physician towards his or her role as health promoter in general, or in the areas of cardiovascular and cancer diseases specifically.

Objectives: To examine the preparation of Israel medical students for the role of health promoter in cancer and cardiovascular diseases.

Methods: The study was carried out over 2 years in two of the four medical schools in Israel: the Sackler Faculty of Medicine at Tel Aviv University and the Faculty of Health Sciences at Ben Gurion University in Beer Sheva. The students (n=172, 70% response rate) were surveyed during 1999-2000 by means of a questionnaire, which included assessment of their training towards the role of health promoter, their clinical experiences and exposure to patients at different stages of illnesses at various medical sites, and the specific skills and relevant knowledge they acquired.

Results: Most of the students’ learning experiences occurred in hospitals with patients at the treatment stage and little time was dedicated to prevention, especially in the community. They demonstrated better knowledge, skills and satisfaction with their learning experiences in CVD than in cancer; and reported having insufficient exposure to several common cancer diseases and lacking examining skills for early detection of cancer. The students in Beer Sheva had significantly more interaction with patients at different stages of CVD and acquired more examination skills than the Tel Aviv students.

Conclusions: A change in the curriculum is urgently needed: namely training medical students in community settings and preparing them to promote the well-being of their patients, including prevention. Attention should be given to launching new learning modes in the pre-clinical and clinical curriculum. We propose that: a) pre-clinical courses include prevention techniques in CVD and cancer, problems of cancer patients, and some examining skills; and b) the clinical phase should integrate oncology concepts and total cancer and CVD care into existing clerkships in the hospitals and in the community.
