Background: Risk factors for injurious falls among elderly people differ from those for falls in general. The characteristics of falls play an important role in determining the risk of hip fracture.

Objective: To investigate the risk factors associated with the fall characteristics known to be associated with the majority of hip fractures, e.g., a lateral fall and a subsequent impact on the greater trochanter.

Methods: In this 6 month prospective observational case-control study 101 individuals aged 65 years and over hospitalized following a hip fracture were interviewed 7–14 days after the accident. Data were also obtained from medical records, focusing on known predisposing and situational risk factors for the fall. We compared the risk factors between two groups: patients who suffered a lateral fall and subsequent impact on the greater trochanter of the femur, and patients who suffered other types of falls.

Results: Only 51.5% of the hip fracture patients reported that they had fallen directly to the side. Apart from age, there were no significant differences between the groups in other factors studied. When considering both fall direction and the area that took the main impact, we found that the majority of patients (85%) reported having fallen onto the posterolateral aspect and/or a fall with an impact on the greater trochanter.

Conclusion: Our findings did not show differences (except for age) in the factors studied between the groups. This study suggests that both fall direction and the area that takes the main impact should be considered in the characteristics of falls that might cause a hip fracture. Characteristics associated with greatest fracture risk include a fall onto the posterolateral aspect and/or a fall with an impact on the greater trochanter. More studies are needed to evaluate potential risk factors associated with this type of injury.

Background: Congestive heart failure is extremely common in octogenarians and is associated with severe fatigue, shortness of breath, recurrent hospitalizations, and death. These patients, many of whom are anemic, are often resistant to standard CHF[1] therapy including angiotensin-converting enzyme inhibitors, beta-blockers and diuretics.

Objectives: To examine whether correction of the anemia (hemoglobin <12 g/dl) in CHF patients lowers their resistance to therapy.

Methods: Forty octogenarians with anemia and severe resistant CHF were administered a combination of subcutaneous erythropoietin and intravenous iron sucrose.

Results: This combination therapy led to a marked improvement in cardiac function, shortness of breath and fatigue, a marked reduction in the rate of hospitalization and a stabilizing of renal function.

Conclusion: Anemia appears to be an important but ignored contributor to the progression of CHF, and its correction may improve cardiac and renal status as well as the quality of life in elderly patients.

Background: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on the subject of gender-associated pathology in the elderly is also scarce.

Objective: To seek eventual gender-related differences in autopsies of elderly patients.

Methods: We analyzed the data extracted from a published report on 93 PMEs[1] performed at a geriatric hospital during the past 20 years.

Results: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P< 0.02). There was no significant difference in the gender distribution of the other diagnoses.

Conclusion: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.

Matrix metalloproteinases are a family of enzymes that degrade different components of extracellular matrix. They play an important role in normal physiologic processes of maintaining tissue integrity and remodeling, as in wound healing, processes of development, and regeneration. However, excessive expression of MMP[1] has been observed in many disease states, including rheumatoid arthritis and osteoarthritis, vascular remodeling in atherosclerosis and aortic aneurysm formation, neoplastic processes, macular degeneration and many others.

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: Although the preferred management of a patient presenting with an acute myocardial infarction is in a coronary care unit, data based on discharge diagnoses in Israel indicate that many of these patients are treated outside such units.

Objectives: To compare the demographic and clinical characteristics, treatment and mortality of AMI[1] patients treated inside and outside a CCU[2].

Methods: We compiled a registry of all patients admitted to three general hospitals in Haifa, Israel during January, March, May, July, September and November 1996.

Results: The non-CCU admission rate was 22%. CCU patients were younger (61.6 vs. 65.5 years), less likely to report a past AMI (18% vs. 34%), and arrived earlier at the emergency room. Non-CCU patients were more likely to present with severe heart failure (30 vs. 11%). Non-CCU patients received less aspirin (81 vs. 95%) and beta-blockers (62 vs. 80%). Upon discharge, these patients were less frequently prescribed beta-blockers and cardiac rehabilitation programs. CCU-treated patients had lower unadjusted mortality rates at both 30 days (odds ratio=0.35) and in the long term (hazards ratio=0.57). These ratios were attenuated after controlling for gender, age, type of AMI, and degree of heart failure (OR[3]=0.91 and HR[4]=0.78, respectively).

Conclusions: A relatively high proportion of AMI patients were treated outside a CCU, with older and sicker patients being denied admission to a CCU. The process of evidence-based care by cardiologists was preferable to that of internists both during the hospital stay and at discharge. In Israel a significant proportion of all AMI admissions are initially treated outside a CCU. Emphasis on increasing awareness in internal medicine departments to evidence-based care of AMI is indicated.

Background: Intestinal malrotation is usually observed in the neonatal period with signs of acute high intestinal obstruction due to midgut volvulus. However, malrotation presenting beyond the neonatal period and well into adult life is associated with a variety of atypical and frequently non-specific gastrointestinal symptoms that may often cause prolonged delay in diagnosis and appropriate treatment.

Objectives: To emphasize the difficulty in predicting the risk of midgut volvulus based on age or symptoms, and to recommend surgery in all patients found to have intestinal malrotation even if they are considered asymptomatic.

Methods: We reviewed 41 patients with malrotation treated over a period of 24 years at the Soroka University Medical Center.

Results: In our series, 27 patients (66%) had acute midgut volvulus while 14 (34%) had malrotation found during investigation of various long-term gastrointestinal non-specific symptoms. Two patients died of total parenteral nutrition-related sepsis following extensive resection of small bowel. A total of 28 patients was available for long-term follow-up and are asymptomatic.

Conclusions: We recommend elective laparotomy and Ladd procedure in all patients found to have intestinal malrotation. This will prevent the catastrophic results of midgut volvulus and a variety of gastrointestinal symptoms wrongly attributed to other conditions in the span of a lifetime.
