Background: Israeli physicians are very familiar with the problem of interruptions during encounters with patients. However, a thorough search of the medical literature revealed only one report of this problem from Israel, and none from other countries.

Objectives: To characterize the phenomenon of interruptions to the patient-physician encounter in a clinic in Dimona and to assess the effect of an intervention program designed to reduce the magnitude of this problem.

Methods: During an 8 day work period in March 1997 all patient-physician encounters were recorded and characterized. An intervention program was then designed and implemented to reduce the number of interruptions. Data were again collected a year after the initial data collection.

Results: During the 8 day study period prior to the intervention program there were 528 interruptions to 379 encounters (mean of 1.39 per encounter). The main causes of interruptions were entrance of uninvited patients to the examination room (31%) and telephone calls (27%). Most of the interruptions occurred during the morning hours between 8 and 10 a.m. (45%) and at the beginning of the week (Sunday 30%). After the intervention program there were 402 interruptions to 355 encounters (mean of 1.13 per appointment, P=0.21).

Conclusions: There was no statistically significant improvement in the number of interruptions following the intervention program. This finding is either the result of a local cultural phenomenon, or it indicates a national primary care health system problem that may require a long-term educational program to resolve it. Further research is needed on the magnitude, causes and consequences of interruptions in family practice and, if warranted, methods will have to devised to cope with this serious problem.

Background: Osteoporosis is the most common human bone disease. It affects millions of persons throughout the world and its prevalence will increase as the population ages worldwide.

Objective: To assess Israeli physicians' attitudes and knowledge with regard to management of osteoporosis.

Methods: A questionnaire was mailed to 1,900 Israeli physicians concerning their attitudes to the management of osteoporosis, their prescribing habits, and their knowledge on the pharmacological treatment of the disease.

Results: Replies were received from 19% of the physicians. The respondents encouraged physical activity and cessation of smoking for all women, and prescribed estrogen replacement as the main treatment for 50-year-old women. A relatively low level of knowledge was found regarding the adequate dosage of several of the pharmacological treatments.

Conclusions: The findings of the present study stress the need to provide clear guidelines and to extend physicians' knowledge regarding the management of osteoporosis.

Background: Small bowel obstruction with perforation is an unusual and rare complication of bezoars.

Objective: To describe our use of emergency laparotomy to treat intestinal obstruction caused by bizarre bezoars.

Conclusions: An aggressive surgical approach to intestinal obstruction in the pediatric disabled or mentally retarded population is recommended.
 

Background: Protruding aortic atheromas are a potential source of stroke and systemic emboli. The single modality currently available for their detection has been transesophageal echocardiography. However, TEE does not allow full visualization of the upper part of the ascending aorta and proximal aortic arch.

Objectives: To investigate whether double helical computerized tomography- both with and without contrast injection - may represent a useful technique for noninvasive detection of PAA in stroke patients.

Methods: Forty consecutive patients ≥50 years of age who sustained a recent ischemic stroke and/or systemic emboli (within 15 days after the onset of the event) were enrolled in the study and underwent TEE and DHCT without contrast injection using thin slice acquisition (3.2 mm thickness and 1.5 mm reconstruction increment). In addition, the last eight consecutive patients, after obtaining an unenhanced scan, underwent a contrast-enhanced DHCT following peripheral intravenous injection of a small amount of contrast material (15 ml of diatrizoate).

Results: PAAs were demonstrated by TEE in 18 patients (45%); in 16 of them (89%) the atheromas were recognized by DHCT. Of the 22 patients without PAA on TEE, DHCT confirmed their absence in 18 (82%). DHCT yielded a sensitivity of 89%, a specificity of 82%, and an overall accuracy of 85%. The total number of protruding plaques detected by TEE was 43, of which 41 (95%) were correctly identified by DHCT. The mean thickness of the plaques was 5.6±2.4 mm on TEE, and 5.4±2.3 on DHCT (P=NS), with a good correlation between the modalities (γ=0.84). Contrast-enhanced DHCT scans demonstrated absolute equivalence to TEE in aortic areas defined as "clearly visualized by TEE." DHCT detected PAA between the distal ascending aorta and the proximal arch in seven patients; these atheromas were not included in the comparative analysis. In these "occult" areas, DHCT may be superior to TEE.

Conclusions: DHCT without contrast injection using thin slice acquisition may become a useful modality for rapid noninvasive detection of PAA. Contrast-enhanced DHCT scans significantly improve imaging quality and may be superior to TEE in the upper ascending aorta and the proximal arch (areas not well visualized by TEE).
