We reviewed the charts of 100 consecutive emergency department (ED) cases of injuries in public buses (not due to actual traffic accidents) seen during 7 months in 1995. There were 29 males and 71 females with a mean age of 55.6-21.4 years, median 60, and range 13-91. 92 were discharged home directly from the ED. 3 were admitted to general surgical wards, and 1 each to the orthopedic, medical and neurosurgical wards, while 2 soldiers were sent for observation to a military clinic.

There were 28 spinal column, 27 head and 25 chest injuries; 1 patient died. There were no significant differences in admissions during the months of the year. 58% of injuries occurred during normal working hours, with a peak incidence at about 1000 hrs. The most common cause was falling while standing, due to sudden acceleration/deceleration or sharp turns.

There are 1900 buses in Tel Aviv which carry 1.1 million passengers daily and most of which are capable of significant acceleration. A high proportion of passengers travel standing, and elderly passengers are more liable to fall when the bus accelerates, decelerates or turns. We calculate a potential national yearly bus injury toll from falls of more than 1000, which often result in significant morbidity and even mortality. A national survey is now being planned.

Results of laboratory tests ordered during a primary care encounter may reveal findings of abnormal liver function tests, including elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia or abnormal coagulation tests. The object of this study was to describe the spectrum of these liver function test (LFT) abnormalities in primary care.

Results of all laboratory tests ordered during 10 months in an urban primary care clinic were retrospectively reviewed and the medical charts of patients with abnormal LFTs were studied. In 217/1088 (20%) of the tests at least 1 LFT abnormality was found in 156 patients. New diagnoses were made in 104 patients. The main diagnostic groups were: non-alcoholic fatty liver changes, Gilbert's disease, acute infectious hepatitis, alcoholic liver disease and cirrhosis and hepatotoxic drug injury. In 60 patients the physician classified the abnormality as negligible and not associated with significant disease. However, an abnormal test that had been ordered for evaluation of a specific complaint, was indeed likely to represent significant disease (X²=29.5, p<0.001). We conclude that finding abnormalities in liver function tests is common in the primary care clinic but does not often indicate significant liver disease.

The use of oral anticoagulant therapy (OAT) to prevent thromboembolism has been widespread in recent years. The concept of high- and low-intensity regimens has facilitated treatment for many, and has lowered the hazards of overly intense anticoagulation. However, a significant proportion of patients suited to the low intensity regimen are not being treated. It is not clear whether its wider use is limited by continued debate, lack of resources, lack of expertise, or other causes. We retrospectively reviewed the medical records of 32 patients treated with OAT administered in the primary care setting. The average age was 66±11 years (range 34-84). 9 were treated with high-intensity OAT: 8 due to artificial heart valves, and 1 due to a hypercoagulable syndrome with recurrent thromboembolism. 23 were treated with low-intensity OAT, 17 of whom had atrial fibrillation. 11 were also being treated continuously with other medication which interacted with OAT or interfered with other coagulation pathways. Such medication included: aspirin, dipyridamole, amiodarone, bezafibrate and allopurinol. Of 414 coagulation tests, 57% and 65% were in the therapeutic range in the high- and low-intensity OAT groups, respectively. There was no major bleeding event, but in 2 of 8 who bled, gastrointestinal bleeding led to hospitalization. Treatment was discontinued in 1 patient because of difficulties in achieving target INR, and in the 2 hospitalized for bleeding. The percentages of test results in, above and below the therapeutic range were similar to those in other large series, for both intensity regimens. We found that a significant proportion of patients were under chronic treatment with other medication which interacted with OAT. To estimate the rate of complications in primary care OAT, larger series are needed. We conclude that OAT can be given and monitored by the family physician, and that awareness of long and short term drug interactions with OAT is mandatory.

Evidence For Casual Household Transmission Of Hiv: Review And Analysis

All reported case-studies in which the author-described route of infection was deemed to be casual household contact were reviewed and analyzed, as well as all sample-based studies designed to estimate the frequency of casual household transmission. Several recurring biased mechanisms of interpretation were found in the studies, the use of which made it impossible to obtain evidence for casual household transmission. After correcting for these interpretations 8 documented cases of casual household transmission were found. Analysis of the sample-based studies indicated 10 cases of casual household transmission, which occurs at a risk of 0.4% per year of contact (95% confidence interval: 0.20 to 0.66).
