 Background: The recent occurrence of a spontaneous intracerebral hemorrhage in Israel’s Prime Minister placed the scrutiny of local and international media on neurosurgeons as they made therapeutic decisions. In the ensuing public debate, it was suggested that extraordinary measures (surgical treatment) were undertaken only because of the celebrity of the patient.

Objectives: To evaluate the criteria used to select surgical versus medical management for SICH.

Methods: We retrospectively reviewed the files of 149 consecutive patients admitted with SICH[1] from January 2004 through January 2006 to our medical center. Their mean age was 66 (range 3–92 years), and 62% were male. SICH localization was lobar in 50% of patients, thalamus in 23%, basal ganglia in 15%, cerebellum in 13%, intraventricular in 6%, and pontine in 1%. Mean admission Glasgow Coma Score was 9 (range 3–15). Risk factors included hypertension in (74%), diabetes mellitus (34%), smoking (14%) and amyloid angiopathy (4%). Fifty percent of patients were on anticoagulant/antiplatelet therapy, including enoxaparin (3%), warfarin (7%), warfarin and aspirin (9%), or aspirin alone (34%).      

Results: Craniotomy was performed in 30% of patients, and ventriculostomy alone in 3%. Rebleed occurred in 9% of patients. Six months after the treatment 36% of operated patients were independent, 42% dependent, and 13% had died. At 6 months, 37% of non-operated patients were independent, 15% dependent, and 47% had died.

Conclusions: One-third of the SICH patients, notably those who were experiencing ongoing neurologic deterioration and had accessible hemorrhage, underwent craniotomy. The results are good, considering the inherent mortality and morbidity of SICH.

 Background: Aspirin is commonly used by elderly patients. In previous studies we found transient changes in renal function induced by low doses of aspirin.

Objectives: To investigate the mechanisms of these effects.

Methods: The study group included 106 long-term care stable geriatric inpatients. Diet and drugs were kept stable. The study lasted 5 weeks; during the first 2 weeks 100 mg aspirin was administered once a day. Clinical and laboratory follow-up were performed at baseline and weekly for the next 3 weeks. The glomerular filtration rate was estimated by creatinine clearance measured in 24 hour urine and serum creatinine, and by the Cockcroft-Gault formula (C-G) equation. Uric acid clearance (Cu acid) was determined from serum concentrations and 24 hour excretion of uric acid. Patients with serum creatinine > 1.5 mg/dl were not included.

Results: After 2 weeks on low dose aspirin, measured creatinine and uric acid clearances decreased significantly compared with the initial values in 70% and 62% of the patients, respectively, with mean decreases of 19% and 17%, respectively (P < 0.001). Blood urea nitrogen increased by 17% while serum creatinine and uric acid concentrations increased by 4% (P < 0.05 for all). The C-G[1] values decreased by 3% (P < 0.05). After withdrawal of aspirin all parameters improved. However, 67% of the patients remained with some impairment in their measured Ccr[2], compared to baseline. Patients who reacted adversely to low dose aspirin had significantly better pre-study renal function (Ccr), lower hemoglobin and lower levels of serum albumin.

Conclusions: Short-term low dose aspirin affected renal tubular creatinine and uric acid transport in the elderly, which may result in a prolonged or permanent deterioration of the renal function. It is suggested that renal functions be monitored even with the use of low dose aspirin in elderly patients.

Background: Israeli youth lead 27 western countries in dieting. The prevalence of eating disorders has been rising in the last 30 years, causing social problems and medical complications.

Objectives: To examine the prevalence of eating disorders among high school students in a region in northern Israel (Misgav) and to examine the relationship between the parents' employment status and the subject’s eating disorder.

Methods: A structured questionnaire was administered to collect demographic data. The short version of the Eating Attitudes Test (EAT-26) was used to evaluate the subject’s attitudes toward and preoccupation with food, dieting, eating, physical appearance, and personal control over eating.

Results: Of 360 students approached, 283 (78%) completed the self-report EAT-26. One of every 5 females and one in every 20 males had an abnormal eating attitude. The rate of pathologic EAT-26[1] results, 20.8%, falls within the high range of similar community-based samples of female adolescents. There were no differences in EAT-26 score between students with an employed or unemployed mother; however, there was a trend for higher EAT-26 scores among those whose father was unemployed (21.4% vs. 12.7%, c2  = 0.14).

Conclusions: The findings support our hypothesis of a relatively high rate of abnormal eating attitudes (as reflected by high EAT-26 score) in this population. Another possible risk factor is having an unemployed father, which warrants further research and attention. Our next step is to introduce an intervention program in the school and to study its effect.

Background: The rate of trauma in the elderly is growing.

Objectives: To evaluate the characteristics of non-hip fracture-associated trauma in elderly patients at a level I trauma center.

Methods: The study database of this retrospective cohort study was the trauma registry of a level I trauma center. Trauma patients admitted from January 2001 to December 2003 were stratified into different age groups. Patients with the diagnosis of hip fracture were excluded.

Results: The study group comprised 7629 patients. The non-hip fracture elderly group consisted of 1067 patients, 63.3% women and 36.7% men. The predominant mechanism of injury was falls (70.5%) and most of the injuries were blunt (94.1%). Injury Severity Score was found to increase significantly with age. The average mortality rate among the elderly was 6.1%. Age, ISS[1], Glasgow Coma Score on admission, and systolic blood pressure on admission were found to be independent predictors of mortality.

Conclusions: Falls remain the predominant cause of injury in the elderly. Since risk factors for mortality can be identified, an effective community prevention program can help combat the future expected increase in morbidity and mortality associated with trauma in the elderly.

Background: The degree of left ventricular dysfunction determines the prognostic outcome of patients with acute myocardial infarction.

Objectives: To define the clinical, angiographic and procedural variables related to LV[1][1] dysfunction in patients with  with anterior wall AMI[1][2] referred for primary percutaneous coronary intervention.

Methods: The sample included 168 patients treated by primary PCI[1][3] for first anterior wall AMI. Clinical, demographic and medical data were collected prospectively into a computerized registry, and clinical outcome (death, reinfarction, major cardiovascular event) were evaluated during hospitalization and 30 days after discharge. Patients were divided into three groups by degree of LV dysfunction (mild, moderate, severe) and compared for clinical, angiographic and procedural variables.

Results: LV dysfunction was associated with pre-PCI renal failure (serum creatinine > 1.4 mg/dl), peripheral vascular disease, high peak creatine kinase level, longer door to balloon time, low TIMI flow grade before and after PCI, and use of an intraaortic balloon pump. On multivariate analysis adjusted for baseline differences, peak creatine kinase level (r = 0.3, P = 0.0001) and door to needle time (r = 0.2, P = 0.008) were the most significant independent predictors of moderate or severe LV dysfunction after anterior AMI.

Conclusion: Abnormal LV function after first anterior AMI can be predicted by door to balloon time and the size of the infarction as assessed by creatine kinase levels. Major efforts should be made to decrease the time to myocardial reperfusion.

 Background: The decision to undergo prenatal testing is influenced by ethnic or religious factors.

Objectives: To evaluate factors that might influence the decision of pregnant women to choose chorionic villous sampling for prenatal testing.

Methods: The study group comprised 239 women referred for prenatal diagnosis who elected to undergo CVS[1]. The data were analyzed according to indication, ethnic group and religion.

Results: Among women undergoing CVS because of advanced maternal age and because of anxiety, we noted a significantly high proportion of unbalanced families, i.e., with three or more children of the same gender and deviated gender ratio. We found a significant excess of males among the Jewish families and a significant excess of females among the non-Jewish families. Jews were over-represented in the monogenic group while Christian Arabs were over-represented in the maternal age/anxiety group.

Conclusions: The proportion of women who chose CVS for prenatal diagnosis varied according to indication, ethnic group and religion. The data in this study indicate that CVS may have been utilized for balancing families with ≥ 3 or more children of the same sex. Christian Arabs chose CVS more often than the other groups. Jewish women may have utilized CVS for family balancing of both sexes, while non-Jews may have utilized CVS for balancing families with ≥ 3 daughters.

 Background: Obesity is an independent risk factor for ischemic heart disease and affects the status of other risk factors for cardiovascular disease.

Objective: To study the attitude of physicians to obesity by examining discharge letters of overweight patients with ischemic heart disease.

Methods: We used the HOLEM database for this analysis. The HOLEM project was designed to study the NCEP (National Cholesterol Education Program) guideline implementation among patients with IHD[1] at hospital discharge. We documented the recording of risk factors and treatment recommendations for IHD by reviewing the discharge letters of 2994 IHD patients admitted to four central hospitals in Israel between 1998 and 2000. A follow-up visit was held 6–8 weeks after discharge, at which time the diagnosis of IHD was verified, risk factor status was checked, height and weight were measured and drug treatment was reviewed.

Results: Mean body mass index was 28.3 kg/m2 and 32% were obese (BMI[2] ³ 30 kg/m2). Only 39.6% of the obese patients and 65.8% of the morbidly obese patients (BMI ³ 40 kg/m2) had "obesity" noted in their discharging letters, and weight loss recommendation was written in only 15% of the obese patients' discharge letters. Acute episodes like acute myocardial infarction and unstable angina did not influence the notation of obesity, and only BMI and the number of additional risk factors were positively correlated with the notation of this risk factor.

Conclusions: Despite the importance of obesity, weight status was not noted and weight loss was not recommended in most of the discharge letters of obese IHD patients.

 Background: Different exercise tests are used to evaluate the functional capacity in chronic obstructive pulmonary disease. The cardiopulmonary exercise test is considered the gold standard, but the 6 minute walk and the 15 step exercise oximetry tests are considerably less expensive.

Objectives: To determine whether reliable data could be obtained at lower cost.

Methods: The study sample consisted of 50 patients with mild to severe stable COPD]1[. All underwent pulmonary function test and the cardiopulmonary exercise test, 6 minute walk and 15 step exercise oximetry test as part of their regular follow-up visit. Functional capacity was graded according to each test separately and the functional capacities obtained were correlated.

Results: The results showed that most of the patients had severe COPD according to pulmonary function tests (mean forced expiratory volume in the first second 46.3 ± 19.9% of predicted value). There was a good correlation between the cardiopulmonary exercise test and the 6 minute walk functional capacity classes (r = 0.44, P = 0.0013). We did not find such correlation between the 15 step exercise oximetry test and the cardiopulmonary exercise test (r = 0.07, P = 0.64).

Conclusions: The study shows that the 6 minute walk is a reliable and accurate test in the evaluation of functional capacity in COPD patients.

Backgound: Colchicine is widely used for treating gout and familial Mediterranean fever. However, studies in animal models have reported ill effects of colchicine on the central nervous system, including cognitive function.

Objectives: To evaluate the cognitive status of elderly FMF[1] patients on long-term colchicine treatment.

Methods: The study group consisted of 55 FMF patients aged 74 ± 5, attending an FMF outpatient clinic and receiving colchicine treatment for 25.1 ± 8.9 years. The Mini-Mental State Examination was used for cognitive evaluation. Patients' scores were compared with accepted age- and education-adjusted cutoff scores, population-based norms, and scores of a matched control group of 56 subjects.

Results: Individually, all colchicine-treated FMF patients scored well above the age- and education-corrected cutoff scores. Overall, there was a large difference, 5.0 ± 1.6, from the expected cutoff points, in favor of the study group scores (P < 0.001). The individual scores of the control group were also above the cutoff points, however with a lower but still statistically significant difference (3.71 ± 1.15 points, P < 0.001). Compared to population-based norms adjusted by age and education, the study group had significantly higher mean MMSE[2] scores (27.2 ± 2.2 vs. 25.5 ± 2.4, P < 0.001). The control group’s scores were also somewhat higher than expected, but not significantly so.

Conclusions: Our results do not support the view that prolonged colchicine treatment may be associated with cognitive impairment. On the contrary, it is possible that long-term colchicine treatment may even confer protection against cognitive decline in patients with FMF.
