The use of different types of total hip implants in medical centers in Israel was surveyed. Questionnaires were sent to all orthopedic ward directors in Israel requesting information on the number of total hip arthroplasties performed between the years 1984-1993, the types of implants used, and whether attending physicians or residents perform the operations. 22 of 24 orthopedic wards responded but 1 ward was excluded because only the results for 1993 were reported. 5 wards reported more and 16 fewer than 50 operations a year. 15 different types of implants were in use in Israel in that period, and in 5 wards 5 or more types of implants were used. Only 1 of the wards performed more than 50 operations a year. We conclude that the indiscriminate use of multiple technologies in wards performing few operations can lead to the long "learning curves" previously associated with poor results. Orthopedic surgeons should resist the impulse to introduce new implants, thus improving results and lowering expenditure. The need for regulating the introduction of new implants is emphasized.

During 1989-1994, there were 322 episodes of Gram-negative enteric bacteremia in 308 children. The incidence increased from 31/100,000 in children younger than 15 years of age during 1989-1991, to 50/100,000 during 1992-1994. The most common pathogens were Klebsiella, E. Coli, Salmonella and Enterobacter. 39% of episodes were nosocomial and a significant increase was recorded for each species during the last 3 years of the study. Klebsiella represented the most common pathogen causing nosocomial bacteremia, while E. coli and Salmonella were the main pathogens causing community-acquired bacteremia. In this study in southern Israel, the incidence of Gram-negative enteric bacteremia was significantly higher in Bedouin children, with the exception of bacteremia due to Salmonella, which occurred mainly in Jewish children.

To determine the prevalence of occupation-related eye injuries, we analyzed the records of 24,632 patients treated at our emergency surgical department over a 3-year period. Occupational accidents accounted for 17.6% of such cases. A third of them (1374 patients) were referred to the ophthalmic emergency room for further examination. In 89% (1223) of these, at least 1 pathological ocular finding was detected, and 8.3% (114) of them were hospitalized. Penetrating eye injuries were found in 5.2%(72). The commonest eye injury was corneal foreign body found in 42.8%.

Acute infectious diseases of the gastrointestinal tract and food poisoning are problems of great importance in the Israel Defense Force (IDF). They involve individual and epidemic morbidity, with impairment of health of individual soldiers and in the activities of units. Outbreaks of gastrointestinal infectious diseases must be reported to the IDF army health branch, which conducts epidemiological investigation. This study is based on data from yearly epidemiological reports for 1978-1989, and from a computerized database for the years 1990-1995. The incidence of outbreaks is characterized by an unstable trend, It was highest at the end of the 80's (68.3 per 100,000 soldiers on active duty) and lowest for the last 2 years (1994-1995, 36.3 per 100,000). The incidence of soldiers involved in food-borne outbreaks has been more stable, constantly declining during the course of the years. There was marked seasonality with a peak in the summer months. Sporadic morbidity was constant in 1990-1995, with a yearly attack rate of 60% in soldiers on active duty. Shigella strains were the leading cause of outbreaks until 1993, while in 1994-1995 their proportion decreased, with an increase in the proportion of Salmonella strains. As to Staphylococcus aureus, its role in causing food poisoning has been characterized by marked changes. Shigella sonnei replaced Shigella flexneri as the leading strain. 73.3% of outbreaks were small, with fewer than 40 soldiers involved, while 5.4% of outbreaks affected more than 100 soldiers. Outbreaks in which a bacterial agent was identified or which occurred in new-recruit bases were larger than those in which a bacterial agent was not identified, or which occurred in active field unit bases. In conclusion, the rates of infectious disease of the gastrointestinal tract are still high, although there has been a marked decrease since 1994. The incidence of outbreaks has also decreased, as well as the role of Shigella as a leading causative agent.

The appearance of focal pulmonary lesions in a patient with a nonpulmonary malignancy is worrisome. Apart from metastasis, the differential diagnosis includes benign conditions such as infectious and granulomatous diseases, enlarged lymph nodes, atelectasis, radiation pneumonitis, and bronchiolitis obliterans with organizing pneumonia (BOOP). CT-guided needle biopsy is not always diagnostic and may not be feasible in very small lesions. Since open lung biopsy is associated with considerable morbidity, many physicians tend to postpone tissue diagnosis for a few weeks and perform a biopsy only if repeat chest CT scans show increase in size or number of the lesions. This approach may lead to undesirable delay of appropriate treatment. We report video-assisted thoracoscopic lung biopsy in 7 patients with nonpulmonary malignancy who developed lung lesions following chemotherapy and/or radiation therapy. Histological examination proved metastatic lesions in only 2. There were no operative complications and recovery was rapid and smooth in all patients. Thoracoscopic lung biopsy is an effective, minimally invasive diagnostic tool that obviates the need for thoracotomy in these patients.

Hemato-oncology patients needing mechanical ventilation for acute respiratory failure (ARF) have an extremely poor prognosis, with a mortality of more than 90%. Over an 18 month-period 17 such patients were admitted to our ICU. Diagnoses included leukemia (11 cases), lymphoma (1), and status post bone marrow transplantation for leukemia, lymphoma or breast cancer (5). Of 8 whose ARF was associated with septic complications due to neutropenia following chemotherapy, 6 survived. Of 9 who developed ARF due to toxic damage to vital organs following high-dose chemotherapy, 2 survived. Those who develop ARF during chemotherapy are expected to have an increase in granulocyte count within days, and have a surprisingly good prognosis. They should be admitted to the ICU and treated aggressively. Those who develop sepsis due their primary disease and whose general condition contraindicates chemotherapy, have an extremely grave prognosis and admission to the ICU may not be warranted.

Radical prostatectomy may cure most patients in whom the malignant tumor has not invaded through the prostatic capsule. Advances in surgical technique and accumulation of experience have decreased the complication rate significantly. Long-term results of surgical treatment are now better than those of other forms of treatment; hence radical prostatectomy is now recommended for men with life expectancies longer than 10 years. Between 1988 and 1995, 164 men with clinical stages T1 or T2 adenocarcinoma were admitted for radical prostatectomy. Most were not offered a nerve-sparing procedure, so as to allow wider, more complete resection. Those who wanted preservation of sexual function underwent the nerve- preserving procedure. In 6 patients operation was discontinued when metastases to the iliac lymph nodes were detected and in 1 when invasion of the pelvic wall was found. 157 underwent radical prostatectomy. Preoperative biopsy revealed a low-grade lesion (Gleason 2-4) in 19.1%, intermediate grade (Gleason 5-6) in 61.8% and high-grade (Gleason 7-9) in 19.1%; however, pathologic grading revealed that only 7.0% had grade 2-4 tumor, 60.5% grade 5-6 and 32.5% grade 7-9. Pathologic staging revealed T2 tumor in 58%, T3 in 38.8% (including microscopic invasion of the capsule or seminal vesicles); microscopic lymph node metastases were found in 3.2%. Tumor invasion through the capsule was found in only 2 of 13 treated with neoadjuvant androgen blockade, compared with 40% in those who did not receive this treatment. There was no operative mortality and only 14.7% has complications. All had urinary incontinence immediately after operation, but regained continence after an average of 4-5 months. 24 were incontinent for more than 12 months, but most of them had only mild stress incontinence. Most patients were impotent after the procedure. There was tumor recurrence, diagnosed by rise in serum PSA, in 26 during an average follow-up of 26.4 months (range 3-93). Cure rate of prostatic cancer by radical prostatectomy may be increased by improved preoperative staging methods and better patient selection; long term follow up is required for determining cure rate.

The homeless population is mobile and does not use ambulatory health care services. Thus the major contact between the homeless and the medical establishment occurs primarily when they are treated for acute symptoms in hospital. We describe the clinical and sociodemographic profile of the homeless who require hospital services. The research population included 50 homeless treated in the emergency room and various departments of our medical center between October 1994 and August 1995. Social workers used a questionnaire relating to clinical, sociodemographic and social factors. Most patients were men, 76% under the age of 50. The most common diagnosis was alcoholism; other diagnoses included back, limb and joint injuries, infections, skin diseases, and general exhaustion. There were subgroups with differing needs within this homeless population for which appropriate rehabilitation programs are proposed.

To assess the prevalence of infection and colonization of the prostate by bacteria, chip tissue samples from 166 patients undergoing retropubic prostatectomy were submitted for bacterial tissue culture. In 28 patients with an indwelling catheter before surgery, E. coli, Klebsiella, Pseudomonas and Enterobacter were the commonest species encountered, the first the most common. In only 7 patients (20%) who didn't have an indwelling catheter before operation was the culture positive. We confirmed that the longer the time the catheter was indwelling before surgery, the greater the likelihood of positive cultures. However, postoperative outcome and morbidity were not related to culture results. We conclude that even though it is worth trying to sterilize the urine and prostate before prostatectomy, the effect on the postoperative outcome is minimal when proper antimicrobial therapy is given perioperatively.

Splenic infarction is a rare disorder. The typical clinical presentation is sudden pain in the left upper quadrant of the abdomen, and awareness to this possibility is the major clue for diagnosis. We describe a 49-year-old man with chronic atrial fibrillation and splenomegaly who was treated with anticoagulants. Because of hematuria, the regular dose of anticoagulant therapy was reduced. The hematuria stopped but he complained of sudden onset of pain in the left upper quadrant. Computerized tomography and isotope scan of the spleen confirmed the clinical suspicion of splenic infarction. Treatment with anticoagulants and analgesics was followed by clinical improvement.

A significant, large minority of patients with chronic obstructive pulmonary disease (COPD) respond favorably to corticosteroid treatment; but the benefit may be outweighed by its side effects. Long-term administration of inhaled steroids is a safe means of treatment. We hypothesized that treatment with inhaled budesonide would improve clinical symptoms and pulmonary function in subjects with COPD, and that the response to an inhaled B2-agonist would individualize steroid responders. In 44 patients with stable COPD in a double- blind crossover trial, we compared a 6-week course of inhalations of 800 mg/d budesonide with a placebo, separated by a 4-week interval when no medication was taken. In 33 out of 42 responders to the B2-agonist who remained in the study, there was a significant improvement in FEV1 of greater than 20% following budesonide inhalation, as compared to placebo. There was also a significant difference between the 2 periods of treatment as to the mean number of B2-agonist inhalations. We conclude that about 1/4 of patients with stable COPD respond to bronchodilators, and treatment with inhaled steroids improves spirometry data and inhaled B2-agonist consumption in about 3/4.

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.

A 40-year-old man had been followed in the pulmonary clinic for prolonged cough. Chest X-ray showed bilateral diffuse interstitial infiltrates with accentuation toward the bases. CT-scan demonstrated a fine diffuse reticulonodular pattern. Transbronchial lung biopsy showed pulmonary alveolar microlithiasis, a rare disease characterized by the presence of concentric calcifications within the pulmonary alveoli. This is the second case of the disease reported in Israel.

Food-withdrawal has been proposed as a possible mechanism for initiating the onset of labor in animals and humans. The hypothesis was based upon the reported increase in deliveries of infants during the Yom Kippur fast. We studied the effect of the fast on full term deliveries of Jewish women, with non-fasting Bedouin women as controls (1988-1995, 1,313 Jewish and 1,091 Bedouin deliveries). To determine the effect of Yom Kippur itself, delivery rates on Sukkot and Yom Kippur were compared in both groups. The mean delivery rate in the Jewish population was significantly higher during Yom Kippur and the day after, than during the 7 days before Yom Kippur (15.1±5.1 and 14.6±4.7 vs 10.7±3.5, p<0.04 and p<0.01, respectively). There was an increase in delivery rate during the 6 hours before the end of the fast. In the Bedouin women there were no changes in delivery rate during any of these periods. There were no significant differences in the rates of deliveries during the Sukkot festival between Jewish and Bedouin women. We conclude that fasting is associated with a significant increase in the rate of deliveries at term.

Implementation of Advanced Trauma Life Support (ATLS) skills among practicing physicians and its perceived utility in their civilian practices, as well as in their potential army combat assignments, was evaluated. 177 physicians in various subspecialties, who were graduates of ATLS training courses, answered a specially designed telephone questionnaire. An unexpectedly high percentage of physicians (47%) had used their ATLS training when called to treat trauma victims. 67% of physicians stressed the contribution of the ATLS course to enhancing their skills. We believe that a properly designed ATLS course for general practitioners would be very beneficial for trauma victims.
