Background: Hip fracture rates are increasing worldwide, and the risk for a second hip fracture is high. The decision to administer antiresorptive treatment is based mainly on bone mineral density and/or a history of previous osteoporotic fractures.

Objectives: To evaluate the contribution of BMD[1], previous fractures, clinical and laboratory parameters to hip fracture risk assessment.

Methods: The study population included 113 consecutive hip fracture patients, aged 72.5 ± 9.4 years, discharged from the Department of Orthopedic Surgery113 consecutive patients, 87 women and 26 men, aged 50-90 years, mean ag. BMD was assessed at the lumbar spine, femoral neck and total hip. The results were expressed in standard deviation scores as T-scores – compared to young adults and Z-scores – compared to age-matched controls. Plasma or serum levels of parathyroid hormone, 25-hydroxyvitamin 3 and urinary deoxypyridinoline cross-links were evaluated.

Results: We observed T-scores ≤-2.5 in 43 patients (45.3%) at the lumbar spine, in 47 (52.2%) at the femoral neck and in 33 (38%) at the total hip. Twenty-eight patients (29.5%) had neither low BMD nor previous osteoporotic fractures. Using a T-score cutoff point of (-1.5) at any measurement site would put 25 (89%) of these patients into the high fracture risk group. Mean DPD level was 15.9 ± 5.8 ng/mg (normal 4–7.3 ng/mg creatinine). Vitamin D inadequacy was observed in 99% of patients.

Conclusions: Using current criteria, about one-third of elderly hip fracture patients might not have been diagnosed as being at risk. Lowering the BMD cutoff point for patients with additional risk factors may improve risk prediction yield.

 Background: Monoclonal gammopathy of undetermined significance is defined by the presence of: low serum and/or urine monoclonal protein level; less than 10% plasma cells in bone marrow; normal serum calcium, creatinine and hemoglobin levels; and no bone lesions on full skeletal X-ray survey.

Objectives: To study the necessity of bone marrow examination for the diagnosis and clinical course of MGUS[1].

Methods: We retrospectively screened the medical records of all patients in whom monoclonal protein was found in the serum during 2001–2002 in the medical laboratories of Sapir Medical Center. Asymptomatic patients who had serum monoclonal immunoglobulin G < 3.0 g/dl or IgA[2] < 2.0 g/dl or IgM < 1.0 g/dl without anemia, renal failure, hypercalcemia or any bone lesions on skeletal survey were eligible. Full records of patients who were evaluated in the hematology clinic were available (group 1). The remaining patients were followed by their family physicians; thus we had access only to their electronic files including laboratory results and new diagnoses (group 2). Demographic and clinical parameters as well as clinical course were evaluated.

Results: Both groups (57 and 255 patients, respectively) had similar demographic, laboratory and clinical characteristics. Bone marrow examination was performed in 30 of 57 patients (group 1): 16 were normal, 8 had an excess of normal plasma cells, and 6 had excess of pathologic plasma cells. However, only in two of the latter six could a diagnosis of multiple myeloma be established. All group 1 patients were followed for 22 ± 11 months and only two developed overt multiple myeloma. During the same period, 6 of 255 patients (group 2) were diagnosed as multiple myeloma and 3 as MGUS in other hospitals. The rest had a stable course with no change in their laboratory values.

Conclusions: Our findings suggest that bone marrow examination should not be performed routinely in patients who fulfill strict clinical and laboratory criteria of MGUS.

 Background: Previous assessments of maternal group B Streptococcus carrier rates in women delivering at Shaare Zedek Medical Center ranged between 3.5 and 11% with neonatal sepsis rates of 0.2–0.9/1000 live births. Because of low colonization and disease rates, routine prenatal cultures of GBS[1] were not recommended, and intrapartum prophylaxis was mainly based on maternal risk factors.

Objectives: To determine whether this policy is still applicable. 

Methods: We performed prospective sampling and follow-up of women admitted for labor and delivery between February 2002 and July 2002. Vaginal and rectal cultures were obtained before the first pelvic examination. GBS isolation was performed using selective broth medium, and identified by latex agglutination and serotyping. Demographic data were collected by means of a standardized questionnaire. Data on the newborns were collected throughout 2002.

Results: Of the 629 sampled women, 86 had a positive culture and a carrier rate of 13.7%. A borderline significantly higher carriage rate was observed among mothers of North American origin (21% vs. 13.1%, P = 0.048), and a higher attack rate in their infants (3.8/1000 compared with 0.5/1000 live births in our general maternal population, P = 0.002). Eight newborns had early-onset neonatal GBS sepsis (a rate of 0.8/1000 live births), but none of them benefited from intrapartum antibiotic prophylaxis.

Conclusions: An increased neonatal disease rate was observed in a population with a higher colonization rate than previously seen. In lieu of the higher carrier rates, we now recommend routine prenatal screening for GBS in our perinatal population.

Contamination of food with streptococci could present with unusual outbreaks that may be difficult to recognize in the early stages. This is demonstrated in a large food-borne outbreak of streptococcal pharyngitis that occurred in 2003 in a factory in Israel. The outbreak was reported to the public health services on July 2 and an epidemiologic investigation was initiated. Cases and controls were interviewed and throat swabs taken. An estimated 212 cases occurred within the first 4 days, the peak occurring on the second day. There was a wave of secondary cases during an additional 11 days. The early signs were of a respiratory illness including sore throat, weakness and fever, with high absenteeism rates suggesting a respiratory illness. As part of a case-control study, cases and controls were interviewed and throat swabs taken. Illness was significantly associated with consumption of egg-mayonnaise salad (odds ratio 4.2, 95% confidence interval 1.4–12.6), suggesting an incubation period of 12–96 hours. The initial respiratory signs of food-borne streptococcal pharyngitis outbreaks could delay the identification of the vehicle of transmission. This could be particularly problematic in the event of deliberate contamination.

 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: Community-acquired bronchopneumonia in children is frequently accompanied by extreme leukocytosis, whereas in adults with the same diagnosis a high leukocyte count is uncommon. Data regarding differences in the serum levels of inflammatory cytokines between children and adults are limited.

Objectives: To compare leukocyte counts and blood levels of various inflammatory cytokines in children and adults diagnosed with community-acquired bronchopneumonia.

Methods: We prospectively evaluated all pediatric and adult patients admitted for bronchopneumonia based on clinical and chest X-ray findings.. Blood was drawn for complete blood count and serum concentration of the following cytokines: granulocyte colony-stimulating factor, interleukins-6, 8 and 10, interferon-gamma, tumor necrosis factor, as well as matrix metalloproteinase-9 and intercellular adhesion molecule-1.

Results: There were 31 children and 32 adults. The patients in both groups had similar parameters of infection severity. None of them required admission to the Intensive Care Unit. Mean (± SD) leukocyte counts in the pediatric and adult groups were 21,018/mm (± 10,420) and 12,628/mm (± 6735) respectively (P = 0.02). Age was inversely correlated with leukocytes in the pediatric group (P = 0.0001). A significant inverse correslation was also found between age and platelet counts. Although cuytokine levels in both groups were not significantly different, age was

Conclusions: The immune response in community-aquired bronchopneumonia is, at least partly, age-dependent.

Background: There is a dearth of organs for liver transplantation in Israel. Enhancing our understanding of factors affecting graft survival in this country could help optimize the results of the transplant operation.




Objectives: To report 3 years national experience with orthotopic liver transplantation, and to evaluate patient and perioperative risk factors that could affect 1 year graft survival.

Methods: The study related to all 124 isolated adult liver transplantations performed in Israel between October 1997 and October 2000. Data were abstracted from the medical records. One-year graft survival was described using the Kaplan-Meier survival curve and three multivariate logistic regression models were performed: one with preoperative case-mix factors alone, and the other two with the addition of donor and operative factors respectively.

Results: Of the 124 liver transplantations performed, 32 failed (25.8%). The 1 year survival was lower than rates reported from both the United States and Europe, but the difference was not significant. Of the preoperative risk factors, recipient age ≥ 60 years, critical condition prior to surgery, high serum bilirubin and serum hemoglobin ≤ 10 g/dl were independently associated with graft failure, adjusting for all the other factors that entered the logistic regression equation. Extending the model to include donor and operative factors raised the C-statistic from 0.79 to 0.87. Donor age ≥ 40, cold ischemic time > 10 hours and a prolonged operation (> 10 hours) were the additional predictors for graft survival. A MELD score of over 18 was associated with a sixfold increased risk for graft failure (odds ratio = 6.5, P = 0.001).

Conclusions: Graft survival in Israel is slightly lower than that reported from the U.S. and Europe. Adding donor and operative factors to recipient characteristics significantly increased our understanding of 1 year survival of liver grafts.

Background: Pertussis is the only vaccine-preventable disease that has re-emerged in Israel. The reported crude incidence of the disease increased 16-fold since 1998.

Objectives: To describe the epidemiology of pertussis and to explain the substantial increase in reported pertussis incidence in Israel in recent years.

Methods: Crude and specific pertussis incidence by age, patient immunization status, hospitalization rate and national immunization coverage rate were calculated from information provided by the public health offices of the Ministry of Health.

Results: The reported crude incidence of pertussis increased from 1–2/100,000 in 1994–98 to 23/100,000 in 2004. The trend was observed in all age groups, being most prominent in infants under age 1 year and in children aged 5–14. The incidence of pertussis was substantially higher in unvaccinated and partly vaccinated compared to fully vaccinated persons. Fifteen percent of notified cases were hospitalized, but in infants under age 1 year the hospitalization rate was 50%. National pertussis immunization coverage by age 2 years was stable during the last 10 years.

Conclusions: There are several possible explanations for the re-emergence of pertussis in Israel. The most plausible reason seems to be the waning of vaccine-induced immunity in face of infrequent natural exposure to the infectious agent and lack of a pertussis vaccine booster dose after age 1.

For children born after 1 January 2005, use of the Sabin oral polio vaccine in combination with the enhanced-potency Salk inactivated polio vaccine as part of the routine vaccination schedule was discontinued. The schedule now includes only IPV [1]. In September 2005, a fifth dose of pertussis vaccine was added for pupils in their second year of elementary school. This article describes the reasons for these changes, which have rendered Israel's routine vaccination program one of the most effective in the world.
