Infection with Legionella remains an important cause of disease and death. We analyzed our laboratory data from 1993 through 1997, augmented by our 20 years of experience. The incidence of Legionella as a cause of pneumonia varied in our study from 5%-9%, with a slight increase during the winter. Isolation of these microorganisms from different water sources was higher during the summer and ranged from 7%-70%.

Special laboratory tests are necessary to diagnose the disease and monitor these bacteria in water samples. The serologic method - indirect immunofluorescent assay -- for 41 serogroups of Legionella was the main diagnostic method used. Legionella sg. 1 was the most frequent cause of the disease, with an incidence of 52% in 1993, decreasing to 15% in 1997. An increase in the incidence of seropositivity to "other Legionellae" is characteristic for our country.

No correlation was found between the incidence of isolation of a specific strain and exposure. However, it is well known that the disease is overtreated but underdiagnosed, which requires reversal. Larger studies of Legionella colonization in water supplies and in air are needed in order to establish the risk of infection. Water sources are presently under-studied, as are respiratory devices in hospitals, or they are not studied at all in Israel, such as in mist machines in supermarkets, in dental clinics, and in ships and airplanes.

Brucellosis Presenting as Acute Abdomen

Usually symptoms of brucellosis are nonspecific and characterized by a wide range of complaints. Although the disease in Israel is almost exclusively food borne (caused by Brucella melitensis in unpasteurized goat milk products) so the main route of infection is the gastrointestinal tract, but gastrointestinal complications are rare, and only sporadic cases of ileitis or colitis have been described.

We present a 43-year-old woman with an acute abdomen, probably due to diverticulitis. It was diagnosed only after blood cultures were positive for Brucella melitensis. We believe that its protean manifestations should be consin addition to the other bizarre presentations of this disease, important in our region.

Meningitis due to Streptococcus bovis is rare. Only 14 cases having been reported in the English literature. All patients (including the patient described) had an underlying disease or were treated by pharmacological agents that predisposed the patient to the infection. Most were treated by monotherapy with penicillin G (or amoxicillin) and recovered.

We describe a 74-year-old woman who had splenectomy as treatment for hairy cell leukemia 6 months before hospitalization for meningitis and sepsis by S. bovis type 2. She was successfully treated with intravenous amoxicillin. There was neither evidence of endocarditis nor carcinoma of the colon. Although the association between S. bovis meningitis and endocarditis or carcinoma of the gastrointestinal tract is not well established, we recommend a full work-up for GI malignancy and endocarditis in every patient with S. bovis meningitis.

Bouveret's syndrome involves gastric outlet obstruction caused by a gallstone in the duodenum. This type of gallstone ileus can be diagnosed and treated endoscopically. Endoscopic stone removal is especially indicated in poor risk patients. A dislodged impacted stone can migrate distally and cause small bowel mechanical obstruction. We report a 51-year-old woman who underwent endoscopic duodenal stone manipulation which resulted in small bowel obstruction.

E. coli meningitis is a disease that occurs in predisposed patients, either as a result of trauma or in neonates after neurosurgery. Recurrent E. coli meningitis in an adult without any apparent predisposition is uncommon, and hydrocephalus complicating bacterial meningitis is even more rare. We report a unique case of a 67-year-old alcoholic man who had had 2 consecutive episodes of E. coli meningitis within 2 months. In both episodes there was a favorable response to ceftriaxone. However, normotensive hydrocephalus appeared a few weeks later, with mental and physical deterioration.

Methotrexate Treatment in Refractory Juvenile Rheumatoid Arthritis

R. Brik

Pediatrics B Dept., Rambam Medical Center, Haifa

The mean time from initiation of methotrexate (MTX) treatment of juvenile rheumatoid arthritis (JRA) to partial remission of clinical symptoms and total clinical remission was assessed. 9 girls and 8 boys, from 3 to 18 years of age (mean 11.4±5.4) with active JRA by American College of Rheumatology (ACR) criteria (5 systemic, 8 polyarticular and 4 pauciarticular disease onset), who failed to respond to adequate courses of non-steroidal anti-inflammatory drugs (NSAID), steroids or disease-modidrugs were studied.

Clinic visits were scheduled at monthly intervals for physical and laboratory assessment disease activity and drug safety. Partial response to MTX was defined a 25% reduction of the active joint count and/or articular severity score. Total clinical remission was defined as in adult rheumatoid arthritis. The duration of disease activity until enrollment ranged from 6 months to 14 years (4.5±3.7 yr); duration of therapy was 3 months to 3 years (14.6±9.3mo) and dosage ranged from 5 to 15 mg/m²/week. Prednisone in doses below 10 mg/day and NSAID were permitted.

14 of 17 patients (82%) had a 25% reduction in joint activity after 6 weeks to 4 months (9.2±3.2 weeks); 10 (59%) went into full clinical remission after 5 to 26 months (14.3±9 months); 3 relapsed after an initial response to treatment, and 4 (23%) did not respond to MTX. The non-responders were males who required higher doses of prednisone (p<0.0001).

MTX appears to be effective therapy for children with JRA. An initial response can be expected in most patients after 9 weeks of treatment, and full clinical remission occurs after a mean of 14 months.

Brucellosis is a classical zoonosis caused by a Gram-negative bacillus of the genus Brucella. Human brucellosis can either be acute or chronic and present with a variety of manifestations, mostly with fever and signs of musculo-skeletal involvement. It may be complicated by involvement of the cardiovascular, central nervous or genito-urinary systems. However, pulmonary brucellosis is a rare complication.

We report a case of miliary and reticulo-nodular brucellar pneumonia with positive blood and sputum cultures and positive serological tests. To the best of our knowledge this is the first case to be reported from Israel of miliary pneumonia with sputum positive for brucellosis.

Aphthous Stomatitis as a First Manifestation of Crohn's Disease in a Child

Y. Gold, S. Reif

Dana Children's Hospital, Tel Aviv Medical Center

The incidence of Crohn's disease has risen dramatically over the past few years. The peak age of onset is in late adolescence, but it rarely occurs in the first few years of life. We describe a 5-year-old boy with recurrent bouts of fever, aphthous stomatitis, and anemia which did not respond to routine antibiotic therapy. It was only after a few months, when the characteristic symptoms of inflammatory bowel disease (IBD): abdominal pain and diarrhea appeared, that the diagnosis of Crohn's disease was made.

This case illustrates the difficulty in diagnosing IBD in young children. The presenting symptoms of IBD in children are often nonspecific and extra-intestinal. There is usually a low index of suspicion by the physician as to the possibility of IBD in a young child.

Proctolectomy with ileal pouch anal anastomosis (IPAA) has become the procedure of choice for the surgical treatment of ulcerative colitis (UC) and familial polyposis (FP). Ithas traditionally been performed in 2 stages, but recently the necessity for an ileostomy hbeen challenged by several authors who recommend a 1-stage procedure.

5 years ago we started to test this policy for treatment of UC and FP. In 48 patients (Group A), 45 with UC, the 2-step procedure, and in 17 of the 27 in Group B with FP, the 1-stage procedure were performed. The indications for surgery were intractable UC in 37 patients in group A and in 5 patients in Group B (p<0.01).

Postoperative infection due to bowel leakage developed in 2 in Group A and in 6 in Group B (p<0.01). Reoperation was necessary in 4 patients (15%) in Group B and only 1 (0.9%) in Group A (p<0.01). Bowel leakage in Group B occurred in 5 (19%) with UC and in only 1 with FP (p<0.05), which responded to medical treatment. All those with UC who developed this complication were relatively malnourished, with serum albumin levels lower than 3.0 g% and were regulated with corticosteroids.

We therefore conclude that the 2-stage IPAA is feasible and safe for the treatment of UC and FP. The 1-stage IPAA should be limited only to FP or good risk UC patients.

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.

Acute appendicitis is the most common surgical problem in pregnancy, when it is difficult to diagnose early because of the physiological changes of pregnancy. We studied the problem in the Negev population and present the main issues in diagnosis and management. Between 1988-96, 26 women were operated on for acute appendicitis during pregnancy (1/3297 deliveries), 3 by laparoscopy. In 13 there was a histopathological confirmation of the diagnosis. Clinical diagnosis was more accurate in the first trimester of pregnancy than in the second or third (p=0.073). Premature delivery rate was higher in both confirmed and unconfirmed acute appendicitis than in other pregnancies (p<0.00001), but without significant differences between the 2 groups with appendicitis. Other indexes of maternal and perinatal morbidity did not differ either.

A prospective study was carried out among elderly patients with community-acquired pneumonia to determine if there are any specific features that could help in deciding whether to hospitalize, or to treat in the community. We concluded that there is no correlation between clinical presentation of pneumonia and outcome, except for impairment of consciousness. Laboratory data showed a correlation between oxygen saturation in arterial blood, levels of hemoglobin and albumin, and outcome. Sputum culture was not helpful in deciding about diagnosis and treatment, which remain empiric. These patients should be treated at home if conditions permit. Recommendations are made for improving such conditions.

We report a 48-year-old man admitted for watery diarrhea, high fever, chills and abdominal cramps. Entero-hemorrhagic E. coli O157:H7 was isolated. This new, dangerous pathogen causes dysentery and complications such as hemolytic uremic syndrome and thrombotic thrombo-cytopenic purpura. These complications can cause renal failure, neurological deficit and death. Recognition of E. coli O157:H7 infection is important since it causes a rare and dangerous condition. To the best of our knowledge this is the first case reported in Israel.

Our experience with living-related liver transplantation is described. In 2 boys and 1 girl, aged 4-4.5 years with acute, fulminating hepatitis A, the presence of very severe jaundice (bilirubin levels > 18 mg%) associated with severe coagulopathy (INR>10) and encephalopathy indicated the need for urgent liver transplantation. In all 3 cases the left lateral hepatic segment of a matched blood type parent was transplanted. None of the donors suffered a serious complication postoperatively and all returned to full activity in 6-16 weeks. The post-transplantation course was uneventful in 1 child, but in the other 2 there was hepatic arterial thrombosis in 1 at 1 day and in the other at 8 days post-transplantation. Early detection of arterial thrombosis by Doppler sonography permitted salvage of the 2 hepatic grafts after thrombectomy and re-anastomosis. In 1 of these 2 children an anastomotic biliary stricture was found 2 months after transplantation. It was corrected at surgery and a percutaneous stent was inserted. All 3 children are alive with normal graft function at 2, 7 and 8 months post-transplantation, respectively. This initial experience indicates that living-related liver transplantation is feasible in Israel. The technique might help to solve our severe organ shortage for children awaiting liver transplantation.

Nursing Home-Acquired Pneumonia: Guidelines for Hospitalization

To determine if there are any specific features of nursing-home acquired pneumonia we carried out a retrospective study in a nursing home between 1995-1996, based on clinical and laboratory data. We found no correlation between these findings and the severity of pneumonia, so it would be hazardous to determine rigid guidelines. These patients should be treated in the nursing home as long as conditions allow, in order to avoid hospitalization.
