Background: Gallium scintigraphy is frequently used in the evaluation of fever of unknown origin, although its utility has been addressed in only a few studies.

Objectives: To evaluate the utility of gallium scintigraphy in the evaluation of patients with FUO[1] in our department.

Methods: We reviewed the charts of all patients from our department who had undergone gallium scintigraphy during the years 1995–2002 for the evaluation of FUO and who met the criteria for the definition of FUO. Demographic, clinical and laboratory data in addition to the results of gallium scintigraphy were documented. The patients were divided into two groups: those with a normal gallium study (group 1) and those with an abnormal gallium study (group 2). The second group was further divided into two groups: those whose gallium study results contributed to the diagnosis of the cause of FUO (group 2A) and those whose gallium study results did not (group 2B).

Results: A total of 102 patients met the study criteria. The male: female ratio was 54:48 and the mean age ± SD was 62.4 ± 20 years. A final diagnosis had been reached in 63 patients (62%), among whom the etiology was infectious in 54%, neoplastic in 19% and immunologic/rheumatic in 16%. Forty-one patients (40% of all the patients) (Group 2) had an abnormal gallium scintigraphy, and in only 21 patients (21% of all the patients) (Group 2A) did the gallium study results contribute to the diagnosis of the cause of FUO. However, in only two patients from Group 2A (2% of all the patients in our study) was the contribution of gallium study considered significant or crucial to the diagnosis of the cause of FUO.

Conclusions: The utility of gallium scintigraphy in the evaluation of FUO is very limited.

Background: Spasticity is a common neurologic disorder with adverse effects on the patient's function. Conservative management is unsuccessful in a significant proportion of patients and neurosurgical intervention should be considered. The mainstay of surgical treatment of spasticity is selective posterior rhizotomy, i.e., section of sensory nerve roots of the cauda equina.

Objective: To report our experience with selective posterior rhizotomy in the treatment of spasticity.

Methods: We retrospectively reviewed our experience in 154 patients who underwent SPR during 30 years. The indication for surgery was spasticity that significantly hindered the patient's function or care and was resistant to conservative treatment. All patients were evaluated for spasticity in the lower and upper limbs, the presence or absence of painful spasms, and sphincter disturbances. The decision

as to which roots to be sectioned, and to what extent, was based mainly on clinical muscle testing.

Results: Reduction of spasticity in the lower limbs was obtained in every case, with improvement in movements in 86% of cases. Painful spasms were alleviated in 80% of cases. Amelioration of neurogenic bladder was observed in 42%. A minority of the patients also showed improvement in speech and cognitive performance. There was no perioperative mortality or major complications.

Conclusion: SPR is a safe and effective method for the treatment of spasticity with long-lasting beneficial effects. We suggest that this method be considered more frequently for patients with spasticity that interferes with their quality of life.

Background: The prevalence of clinical manifestations and laboratory parameters in systemic lupus erythematosus differ among various ethnic groups. Few studies have reported on SLE[1] in Arabs.

Objectives: To summarize the demographic, clinical and laboratory features of Arab SLE patients and to compare them with other series from different Arab countries.

Methods: We reviewed the charts of all Arab SLE patients who had been seen at the Carmel Medical Center in Haifa, the Nazareth Hospital and the Holy Family Hospital in Nazareth, and a professional clinic (a referral outpatient clinic of the largest health maintenance organization in Israel) in Acre – all cities in northern Israel. Only patients with symptoms of more than one year were included. Demographic, clinical and laboratory parameters were documented and compared with those of four series from different Arab countries.

Results: The study group comprised 34 patients. The majority of the patients was Moslem; there were a few Druze and one Christian. There was no statistical difference between our patients and any of the other Arab series in terms of arthritis, neuropsychiatric manifestations and VDRL. The presence of serositis and mucocutaneous manifestations was significantly lower in our series compared to some of the other series. However, there was significantly less renal involvement in our patients compared to each of the other series.

Conclusions: The prevalence of most clinical and laboratory parameters in Israeli Arab SLE patients is comparable to that of other series of SLE patients from different Arab countries. The prevalence of renal involvement in Israeli Arab SLE patients seems to be lower than in SLE patients from different Arab countries.

Background: About one-third of patients with severe ulcerative colitis do not respond to conventional therapy and require urgent colectomy. It was recently shown that cyclosporin is effective in some of these patients.

Objectives: To review the current experience of six hospitals in central Israel that used cyc-losporin in patients with severe ulcerative colitis.

Methods: The files of all 32 patients treated with cyclosporin for corticosteroid-resistant ulcerative colitis were reviewed. Activity of disease was measured by a clinical activity, index colonoscopy and laboratory tests.

Results: The average duration of treatment with intravenous cyclosporin was 12.7 days (range 9–28) after which the disease activity index dropped from an average of 14.22 to 4.74. The mean time for response was 7.5 days (4–14). Twelve patients (40%) required surgery within 6 months and another 6 patients (18.8%) were operated on after more than 6 months. Twelve patients (37%) maintained remission for at least 6 months and did not require surgery. In one patient treatment was stopped because of non-compliance and one was lost to follow-up. There were numerous side effects, but in only one case with neurotoxicity was treatment withdrawn.

Conclusions: Cyclosporin is a relatively safe and effective treatment for severe ulcerative colitis. It induced long-term remission in 37% of the patients, and in those who required surgery the treatment resulted in an improved clinical condition before the operation.

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: Acute rheumatic fever is considered a relatively uncommon disease in developed countries. Although cases are encountered in the Nazareth area in Israel, no systematic study of this disease has been done in the last 20 years.

Objective: To study the incidence and characteristics of acute rheumatic fever cases in the Nazareth area during the last decade.

Methods: Cases of acute rheumatic fever diagnosed according to the modified Jones criteria were identified in two hospitals in the Nazareth area during the 10 years. These two hospitals receive about 75% of non-obstetric referrals to the emergency room. Clinical, laboratory and treatment data of these patients were documented and the incidence of disease calculated. The population census in the Nazareth area was obtained from the Central Bureau of Statistics.

Results: Forty-four patients, with a mean age of 18 years, were identified. The mean annual incidence was 5 cases/100,000 population. Arthritis was found in 98% of the patients (migratory in 52%) and carditis in 34%, but only one patient had a subcutaneous nodule, and none had either erythema marginatum or chorea. Only one patient with carditis developed heart failure a few months later due to severe mitral stenosis.

Conclusion: Rheumatic fever in the Nazareth area is still manifest. The mean age of the patients was higher than found previously. In only half of the patients was the arthritis migratory, with other major manifestations of rheumatic fever found only rarely.
