2 cases of malaria in family practice are described in a 26- and a 50-year-old woman. Both probably could have been prevented had common chemoprophylactic drugs been taken. The risk of malaria is greater than the risk of possible side-effects of the drugs commonly used by travelers for prevention. Family physicians must be aware of the possibility of malaria in young people with fever, especially those who have travelled to equatorial areas and special attention should be given to encourage chemoprophylaxis.

Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%).

We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers.

The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases.

Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.

Massive splenomegaly is defined as a spleen weighing about 10 times normal weight. We describe a 36-year-old man who had huge splenomegaly and secondary pancytopenia simulating malignant lymphoma for about 3 months. Splenectomy was necessary because of the suspicion of hematologic malignancy, especially isolated lymphoma of the spleen, and pain and mechanical abdominal disturbances.

On operation, the spleen was 25 cm long and weighed 250 g. There was florid, reactive follicular lymphoid hyperplasia. Immunohistochemical staining with CD-20(L26), CD-45Ro(UCHL), bcl-2 oncoprotein (Dakopatts), EBV (anti-EBV mol weight 60 KD, Dakopatts) was consistent with reaction to EBV infection and not with follicular lymphoma. Lack of PCR amplification using DNA extracted from paraffin-embedded splenic tissue indicated absence of a monoclonal B cell population carrying rearranged immunoglobulin genes. The lymphocytic population was proven polyclonal by the negative results of PCR for the bcl-2 gene rearrangement. EBV seroconversion from high titer antibodies of anti-EBV-VCA-IgM to negative, and from negative EBNA to positive was consistent with an apparent primary EBV infection.

We have not found on computerized search a previous report of reactive follicular splenic hyperplasia to EBV infection causing huge splenomegaly, with or without EBV-induced infectious mononucleosis.

Computerization in a Community Health Service Provider

Boaz Porter

Maccabi Health Services, Beer Sheba

As the second largest health service provider organization in Israel, we have been progressively computerized. The process was begun in 1988, focusing on improving administrative and financial processes.

Today there is a single centralized database for 6,000 users. The system monitors member eligibility, accounting procedures and clinical processes, including diagnoses, laboratory tests, imaging procedures and drug-prescribing. The potential of the computer for physician support is now being realized through integration of clinical guidelines and reminder systems into the computerized clinical record. In addition, the centralized database is used for quality improvement, facilitating cost-effective drug-prescribing and efficient use of technology.

The establishment of a computerized working environment for 2,000 physicians and 4,000 other healthcare workers serving 1.3 million patients is a unique model for the development of community health services. Data regarding demographics, disease patterns, drug-prescribing, use of new technology and costs are now readily available to all, from senior management to the individual physician in independent practice.

The computer revolution has also presented a new set of problems such patient-record confidentiality and the effect of the computer on the physician-patient encounter.

Cryptococcal meningitis (CM) is common in the immunocompromised (especially due to AIDS), but also occurs in immunocompetent subjects. CM can complicate cryptococcal pneumonia (CP) not only in the immunocompromised but also in the immunocompetent. We describe a healthy 26-year-old man who developed a prolonged lung infection. Diagnosis of cryptococcal pneumonia was established from bronchoscopic washings. He recovered spontaneously, so no antifungal treatment was given.

4 months later he was admitted with cryptococcal meningitis and was treated successfully with amphotericin B. An extensive immunologic study revealed no abnormalities. Since CM can complicate cryptococcal pneumonia, it is recommended that patients with CP be followed, even if recovery is apparently complete.

Findings in occupational health examinations of a regional service are analyzed. The service provides pre-employment, surveillance and work-capacity evaluations for about 150,000 workers from many types of work-sites and occupations. The average number of pre-employment examinations (during 1993-97) was 4,800/year, and there were relevant pathological findings in about 6.6%. Most findings involved the respiratory (11%) and cardiovascular systems (10%) or eyes (10%).

The average annual number of surveillance system examinations was 10,750. There were relevant findings in about 16%, mainly of the respiratory system (17%) and noise-induced hearing damage (about 80%).

Work-capacity examinations constituted about 35% of the work-load (9,250 examinees/year). In 53% a significant health problem affecting an individual's job performance was identified. Pathological findings were found in the musculoskeletal (21%), cardiovascular (7.5%), respiratory (3%), and neurological systems (2%).

Occupational health examinations can identify areas in which prevention and intervention or cooperation with other medical specialties are indicated, as well as specific topics requiring further training of occupational physicians.

Adult-onset Still's disease (AOSD) is characterized by a spiking fever and diverse clinical findings; the diagnosis is often delayed for months or even years. The only positive laboratory finding is neutrophilic leukocytosis. Since 1987, the diagnostic importance of elevated serum ferritin levels has been discussed in numerous papers, but is not yet among the diagnostic criteria for AOSD. We describe a case in which the finding of extreme hyperferritinemia enabled prompt diagnosis and treatment.

Equine Rhodococcus Equi Pneumonia: First Report in Israel and its Significance for Man

Rhodococcus equi is an important pathogen in young horses. In recent years it has been increasingly recognized as an opportunistic infectious agent in patients with immune deficiency. The increase in recognized cases may be related to the increased prevalence of AIDS. However, more cases may have been recognized lately due to increased awareness of the pathogenicity of this bacterium. Based on medical reports, there appears to be an association between Rhodococcus equi infections and exposure to animals, horses in particular.

During the past year, 2 cases of rhodococcus pneumonia were diagnosed in foals in Israel. This information deserves the attention of the local medical community because of the zoonotic potential of Rhodococcus equi and the danger of its becoming more common. The climate in Israel is conducive to its growth and viability and since it flourishes in an environment with horses, the significant growth in our equine industry in recent years may contribute to an increase in Rhodococcus infections.

There is an international epidemic of violence in the emergency department (ED) which threatens medical staff daily. The problem is underestimated in Israel and there are as yet no regulations of the Ministry of Health and the Bureau of Security and Safety that deal with the problem.

At the beginning of 1997 we conducted a retrospective survey to estimate the extent of this problem and to define its causes and the various options for management. An anony-mous questionnaire was given to all permanent workers of our ED: physicians, nurses and reception clerks, as well as physicians who worked in the ED during evening and night shifts at least twice a week.

74% of (questionnaire) responders experienced violent events, most of them 5 or more times during the previous 2 years. Violence was experienced by 90% of nurses, 70% of physicians and 64% of clerks. The main reason for violence was prolonged waiting in the ED. Other causes were dissatisfaction with treatment, refusal to leave the ED, and language that displeased the patient.

Most violent patients were middle-aged men, of whom alcohol and drug users were only a small proportion. Most victims of physical violence called hospital security personnel, but only a third of the victims of verbal violence pressed charges. Half of the staff who were physically attacked called the police and most pressed charges. Only 2 attackers were convicted; charges were dropped against 3 because of "lack of public concern." We were unable to ascertain the results of the other charges. Most victims of violence didn't press charges because of fear resulting from threats of the patient and/or family.

The violent patient was usually characterized by responders as a middle-aged man, sober, of low socioeconomic level, impatient, with a bad previous hospital experience, dissatisfied with treatment and who insisted on being admitted to hospital.

Suggestions for violence management by questionnaire- responders included 24-hour police protection and a training program in violence management for hospital security and medical staff.

Hypercalcemia is a common metabolic disorder, especially in the elderly. The most common etioloare hyperparathy-roidism or malignancy, most often of the lung, breast, kidney or hematological system. Because hypercalcemia is an uncommon manifestation in urinary tract epithelial tumors, especially those of the renal pelvis, we present a man aged 62 years with hypercalcemia due to renal transitional cell carcinoma.

During the August 1998 heat wave in Tel Aviv we admitted many patients for acute heat-related illness; 6 had severe heat stroke and were admitted in critical condition. We describe their clinical courses during the first 5 days of hospitalization, including response to treatment and implications for future management of this disorder.

The mean APACHE II score of the 6 was 30±3.5 and mean Glasgow Coma Scale rating 3.5±0.5; they were in hypovolemic shock and respiratory failure, necessitating mechanical ventilation. Despite early effective therapy (core temperature in all was reduced to less than 398C in less than 1 hour), there was 1 death (mortality 15%) and 4 required further intensive care for life-threatening multiple organ failure.

During severe heat waves a significant number of referrals for acute heat-related illness must be anticipated, possibly overwhelming admission capacity of regional intensive-care units. Severe heat stroke complicated by multi-organ failure is not necessarily related to prior physical activity. Although important in determining prognosis, early treatment does not prevent severe complications. Mechanisms regulating body heat may remain disturbed for days following early treatment and apparent stabilization, mandating continued hospitalization.

Relapse of Sarcoidosis after Alternative Medical Treatment

Reference to alternative medicine frequently appears in newspaper headlines, advertisements and in articles in medical journals. The practice of alternative medicine has increased, even as the number of critical articles warning of deleterious effects have also increased. Public demand is strong and growing, but there are no clear rules as to what is not permissible, particularly when treatment is not by qualified physicians. There are still no clear indications and contra-indications for complementary (not alternative) medicine in patients with organic injuries and life-threatening conditions. However, it is obvious that in these patients complementary medicine should not be substituted for conventional therapy.

We present a 32-year-old man with sarcoidosis who discontinued conventional therapy on his own initiative and began alternative medicine (homeopathy) with subsequent deterioration in his condition. He was hospitalized for a relapse of his sarcoidosis which required large doses of corticosteroids.

Several studies have documented the impact of clinical pharmacy services on patient care and drug costs in hospital wards. However most hospitals in Israel do not provide such services and until recently their benefits in local health care have not been demonstrated. We therefor determined whether the activity of a pharmacist in the medical department of a medical center leads to improved quality of drug utilization and reduced costs.

During the first 3 months of the clinical pharmacist's work all interventions and consultation were documented. The effect of these interventions on drug costs was calculated by the change in drug acquisition costs during the study period compared with those of preceding months, as well as in the other 5 medical departments of the hospital without clinical pharmacy services.

During the study period the pharmacist joined 44 clinical rounds in which he documented 40 consultations in response to physicians' requests for drug information and 42 interventions on his own initiative. The pharmacist's recommendations were accepted in 38 of the 42 cases (90%). In 10 cases the pharmacist's initiative in improving the quality of drug therapy led to an increase in drug acquisition costs. However, the overall drug costs during the study period decreased 12.6%. During the same period drug costs in the other medical departments decreased only 2.2%.

The results of this study conform with those of many other studies that show a beneficial impact of the clinical pharmacist on the quality of drug therapy and on drug costs. They indicate that the clinical pharmacist can play a crucial role in the medical department.
