Background: Diabetes mellitus is a serious, costly and growing public health problem. Very few studies have been published on the economic impact of diabetes in Israel.

Objective: To estimate health fund expenditures and rates of hospitalization for general conditions among the diabetic population in Israel.

Methods: The total number of hospitalization. All hospitals in Israel were included.

Results: There were 618,317 general admissions for a total of 3,005,288 hospitalization days. Analysis by age revealed that diabetic patients over age 45 represented 18.3% of all admissions and 17.5% of all hospitalization days. The average stay in hospital expenditure of the GSF for general medical conditions among diabetic patients in 1998 was estimated at US $173,455,790, of which 57% accounted for the daily hospitalization cost. Of the total hospital expenditures for that year, 13.3% was allocated to patients with diabetes of whom 96.4% were over 45 years old.

No significant difference was found between males and females.

Conclusion: Hospital expenditures for diabetic people increase with patient age and represent one-fifth of the total health insurance expenditure for the middle-aged and elderly population.

Objective: To investigate whether cigarette smoking has an additive effect on the clinical presentation and course of disease in Helicobacter pylori-positive dyspeptic patients.

Patients and Methods: The study group comprised 596 consecutive H. pylori-positive dyspeptic patients (334 males and 262 females, mean age 50.6, range 12--81 years). Following upper gastrointestinal endoscopy, patients were subdivided by diagnosis as follows: Non-ulcer patient group (n=312: gastritis 193, duodenitis 119), gastric ulcer (n=19), and duodenal ulcer (n=265). H. pylori infection was confirmed by histology and/or rapid urease test. In addition, 244 patients had a positive 14C-urea breath test prior to antimicrobial treatment. The patients' medical history and smoking habits were obtained using a detailed questionnaire completed by the patients and their referring physicians.

Results: There were 337 non-smoking patients, 148 current smokers and 111 past smokers. Gastric and duodenal ulcers were significantly less prevalent in non-smokers than in current or past smokers (gastric 1.8%, 4.1%, 6.3%; duodenal 39.8%, 50%, 51.4%, respectively) (P0.05). The incidence of gastrointestinal bleeding was significantly lower in non-smokers than in current or past smokers (7.1%, 8.1% and 20.7%, respectively) (P0.05). Bacterial density, as assessed by the UBT value in 244 patients, was higher in non-smokers (mean 352.3273 units) than in past smokers (mean 320.8199) or current-smokers (mean 229.9162) (P0.05). Logistic regression analysis revealed that male gender, current smoking, and immigration from developing countries were all significant independent risks for developing duodenal ulcer, while only past smoking was associated with a higher rate of upper gastrointestinal bleeding in the past.

Conclusions: In H. pylori-positive dyspeptic patients, current smoking as well as male gender and immigration from developing countries are associated with an increased risk for duodenal ulcer. This effect does not seem to be related to the bacterial density or increased urease activity of H. pylori organisms.

Objective: To investigate the clinical, laboratory and radiological findings of the disease.

Methods: During the years 1995-88 five patients with primary epiploic appendigitis were diagnosed at our institution. The clinical, laboratory and imaging results were summarized and compared to previously reported series. Emphasis was placed on the computed tomography findings, which are the gold standard for diagnosis.

Results: All our patients (two males and three females, mean age 47 years) presented with left lower quadrant abdominal pain. CT proved to be the imaging modality of choice in all patients by showing a pericolic fatty mass with an increased attenuation as compared to normal abdominal fat. In all cases the mass was surrounded by a high attenuation rim, and focal stranding of the fat was observed. In no case was there thickening of the adjacent bowel wall. This serves as an important, and previously unreported, clue for diagnosis.

Conclusion: Primary epiploic appendagitis is a relatively rare condition that may be clinically misdiagnosed, resulting in unnecessary surgical intervention. Judicious interpretation of CT may lead to early diagnosis and ensure proper conservative treatment.

Objective: To describe the epidemiology of ceftazidime-resistant K. pneumoniae in our medical center, as representing the situation in tertiary care hospitals in Israel.

Methods: We vigorously restricted the use of ceftazidime in the ICU and enforced barrier precautions. The susceptibility rate of K. pneumoniae was surveyed in the ICU and throughout the hospital before and after the intervention in the ICU.

Results: Following the intervention, the susceptibility rate of K. pneumoniae increased from 11% (3/28) to 47% (14/30) (P0.01) among ICU isolates, from 55% (154/280) to 62% (175/281) (P=0.08) among total hospital isolates, and from 61% (50/82) to 74% (84/113) (P0.05) among total hospital blood isolates, although no additional control measures were employed outside the ICU.

Conclusions: The epidemiology of ceftazidime-resistant K. pneumoniae in our medical center is similar to that reported from other centers around the world. Early awareness to the emergence of this resistance, identification of the source of the epidemic, and prompt action at the putative source site may reduce the rate of acquisition and spread of such resistance inside and outside of the source unit.

Background: Most corneal damage induced by contact lenses is due to interference with corneal oxygenation.

Objective: To investigate the effect on the rabbit cornea of a rigid gas-permeable contact lens with a newly designed periphery.

Method: We fitted New Zealand white rabbits (n=12) with RGP[1] contact lenses that were identical in all respects except for the design of the periphery. In each animal, one contact lens had an innovative periphery consisting of a microscopic diffractive relief lathed on the back surface; the other contact lens was of a conventional design. The lenses were worn continuously for 7 days. During this experimental period and for 1 additional week we assessed the corneal damage by daily testing lactic dehydrogenase activity in the tears.

Results: On the last day of the experimental week and the first 3 days of the healing period, mean tear LDH[2] activity was significantly lower in the eyes with the new contact lens design than in eyes with the conventional lenses.

Conclusions: The novel periphery design reduces corneal damage resulting from contact lens wear, as reflected by LDH levels in the tears. The new design probably facilitates the flow and exchange of tears under the contact lens, resulting in improved metabolism of the cornea. These findings may also prove applicable to soft contact lenses.

Background: *Previous descriptive studies have demonstrated the problematic nature of physicians' attitudes toward battered women. However, little empirical research has been done in the field, especially among the various medical specialties.

Objectives: To compare the approach and feelings of competence regarding the care of battered women between primary care and non-primary care physicians. The non-primary care physicians who are likely to encounter battered women in the ambulatory setting are gynecologists and orthopedists.

Methods: A self-report questionnaire formulated for this study was mailed to a random sample of 400 physicians working in ambulatory clinics of the two main health maintenance organizations in Israel (300 primary care physicians, 50 gynecologists and 50 orthopedists).

Results: In both physician groups, treating battered women tended to evoke more negative emotional states than treating patients with infectious disease. The most prevalent mood state related to the management of battered women was anger at her situation. Primary care physicians experienced more states of tension and confusion than non-primary care physicians and had lower perceived self-efficacy and self-competence in dealing with battered women.

Conclusions: Though both physician groups exhibited negative feelings when confronting battered women, the stronger emotion of the primary care physicians may indicate greater sensitivity and personal awareness. We believe that more in-service training should be introduced to help physicians at the undergraduate and postgraduate levels to cope both emotionally and professionally with these patients.
