Background: Arabs in Israel have high morbidity and mortality from diabetes and cardiovascular disease. Obesity is a risk factor for both conditions.

Objectives: To investigate the prevalence of obesity (body mass index > 30 kg/m²), subjects' knowledge and behaviors, and their reports on practices of health-care professionals regarding body weight among Arabs and Jews.

Methods: The study participants (n=880) were randomly sampled from the urban population of the Hadera district in Israel. Data on demographic, socioeconomic and lifestyle characteristics; reports on height, current body weight and body weight at the age of 18 years; knowledge and behavior; and health-care professionals' practices with regard to body weight were obtained by interview. Anthropometric measurements were performed subsequently.

Results: Information on BMI[1] was available on 868 participants (49% Arabs, 49% women, median age 46 years). Although the median BMI did not differ significantly between Arabs and Jews at age 18, the prevalence of current obesity was 52% in Arab women compared to 31% in Jewish women (P < 0.001), and 25% in Arab men compared to 23% in Jewish men (P = 0.6). On multivariate analysis, obesity was significantly associated with age, BMI at the age of 18 years, leisure time physical activity and cigarette smoking, but not with ethnicity. Fewer Arabs reported measuring their body weight and Arab women were less frequently advised to maintain an active lifestyle.

Conclusions: The high prevalence of obesity among Arab women may be explained by lifestyle characteristics. Prevention of obesity in Arabs should be directed at women and should start preferably before adulthood.

Background: Head injuries, especially in young children, are frequent and may cause long-lasting impairments.

Objectives: To investigate the outcome of head and other injuries caused by diverse mechanisms and of varied severity.

Methods: The population consisted of Jews and Arabs (n=792), aged 0–17 years old, hospitalized for injuries in six hospitals in Israel. Caregivers were interviewed during hospitalization regarding circumstances of the injury and sociodemographic variables. Information on injury mechanism, profile and severity, and length of hospitalization was gathered from the medical files. Five months post-injury the caregivers were interviewed by phone regarding physical limitations and stress symptoms.

 Results: Head injuries occurred in 60% of the children, and of these, 22.2% suffered traumatic brain injury with loss of consciousness (type 1). Among the rest, 22% of Jewish children and 28% of Arab children remained with at least one activity limitation, and no statistically significant differences were found among those with head or other injuries. The odds ratio for at least two stress symptoms was higher for children involved in transport-related injuries (OR[1] 2.70, 95% confidence interval 1.38–5.28) than for other mechanisms, controlling for injury profile. No association was found between stress symptoms and injury severity.

Conclusions: Most children had recovered by 5 months after the injury. Residual activity limitations were no different between those with head or with other injuries. Stress symptoms were related to transport-related injuries, but not to the presence of TBI[2] or injury severity.

Background: It is not entirely clear when and how steroids should be used to treat trichinellosis.

Objectives: To describe the course of consecutive patients with trichinellosis treated with antihelminthic drugs with and without the addition of prednisone.

Methods: We extracted data from the hospital records of 30 patients hospitalized for trichinellosis contracted after eating poorly cooked pork that came from two pigs killed in the Golan Heights, and contacted them for follow-up 5–6 weeks and 6 months after hospital discharge.

Results: All the patients who attended a party and ingested the infected pork (100% attack rate) were hospitalized after 2–16 days (median 9 days); 29 were symptomatic and 1 patient without symptoms had creatine phosphokinase levels 17.9 times above the upper limit of normal. Twelve of 23 patients (52%) treated with antihelminthic drugs without prednisone were rehospitalized with worsening fever, increased peripheral blood eosinophil counts, but decreasing CPK[1] values. These patients and another seven at the time of admission were treated with prednisone 40 mg/day for 5 days in addition to antihelminthic drugs for at least 14 days. All became asymptomatic within 24 hours and were asymptomatic 6 weeks and 6 months later.

Conclusions: Worsening symptoms in patients treated with antihelminthic drugs alone is common. A short course of prednisone is safe and alleviates symptoms due to tissue larvae in patients with trichinellosis.

Background: Mucositis and dermatitis are frequently encountered in patients treated with radiochemotherapy. Dead Sea products that contain minerals and different substances have proved effective in treating various skin diseases.

Objectives: To evaluate the effectiveness of Dead Sea products in reducing acute radiochemotherapy‑induced side effects in patients with head and neck cancer.

Methods: In this phase 2 study we compared the outcomes in 24 treated patients and 30 conventionally treated patients matched for age, tumor site, and type of treatment. The Dead Sea products comprised a mouthwash solution (Lenom®) and a skin cream (Solaris®) used three times daily for 1 week before, during, and up to 2 weeks after completion of radiotherapy. Mucositis and dermatitis were evaluated using common toxicity criteria.

Results: Thirteen treated patients (54%) had grade 1-2 and none had 3-4 mucositis, while 17 controls (57%) had grade 1-2 and 4 (13%) had grade 3-4 mucositis. Thirteen treated patients (54%) had grade 1-2 dermatitis; there was no instance of grade 3-4 dermatitis, while 11 patients in the control group (37%) had grade 1-2 and 5 (17%) had grade 3-4 dermatitis. More patients in the control arm needed a break than the patients in the treatment arm (P = 0.034[T1]).

Conclusions: The two Dead Sea products tested decreased skin and mucosal toxicity in head and neck cancer patients receiving radiochemotherapy.
 

Background: Surgery for spinal stenosis is a frequent procedure in elderly patients. Presentation, hospital course and outcome of disease, including pain perception, may vary among patients of different ethnic origin.

Objectives: To evaluate whether differences in various medical indicators can explain differences in pain perception between two ethnic groups

Methods: We conducted a case-control study on the experience of two spinal units treating a mixed Arab and Jewish population, and compared the data on 85 Arab and 189 Jewish patients undergoing spinal lumbar surgery.

Results: Arab patients were younger (P = 0.027), less educated (P < 0.001), had a higher body mass index (P = 0.004) and included a higher proportion of diabetics (P = 0.013). Preoperative pain intensity (P = 0.023) and functional disability (P = 0.005) were more prominent, and factors associated with pre- or postoperative pain perception differed between the two ethnic groups. Despite these differences, results on follow-up were similar with respect to pain perception and level of disability.

Conclusions: A better understanding of ethnic differences is crucial for predicting surgery outcomes.

Background: Patients with end-stage renal disease are at high risk of mycobacterial infection.

Objectives: To analyze the difficulties in reaching an accurate diagnosis of tuberculosis in dialysis patients.

Methods: We conducted a retrospective follow-up of patients who attended our peritoneal and hemodialysis units during the 10 year period 1995–2005.

Results: Our dialysis unit diagnosed 10 cases of tuberculosis caused by Mycobacterium tuberculosis and 9 cases of Mycobacterium other than tuberculosis. In the former group, five patients had mycobacterium in the sputum, which was diagnosed by intraabdominal mass biopsy in one, culture of the gastric juices in one, and pleural fluid culture or pleural biopsy in three. One of these patients was suffering from pleural TB[1] as well as Potts disease. Of the patients with Mycobacterium other than tuberculosis, five were diagnosed by sputum cultures, three by urine cultures and one in peritoneal fluid. Differences in treatment and outcome were also reviewed.

Conclusions: The diagnosis of TB in dialysis patients should be approached with a high index of suspicion. It is clear that extensive diagnostic procedures are required to ensure an accurate diagnosis of the disease. Tuberculosis incurs a significant added burden due to the need for isolation of infected patients within the dialysis unit. Treatment of patients with Mycobacterium other than tuberculosis should be addressed individually.

Background: Studies have found ethno-cultural disparities in health care delivery in different countries. Minority populations may receive lower standards of care.

Objectives: To test a hypothesis that Jewish Ethiopian women may be receiving less preventive recommendations than other women in Israel.

Methods: A telephone survey was conducted using a structured questionnaire designed specifically for this study in Hebrew, Russian and Amharic (Semitic language of Ethiopia). The study group included 51 post-menopausal women of Ethiopian origin, aged 50–75. The control group included 226 non-Ethiopians matched by age, some of whom were immigrants from the former Soviet Union. The questionnaire dealt with osteoporosis and breast cancer screening and prevention.

Results: All the parameters measured showed that the general population received more preventive treatment than did Jewish Ethiopian women, including manual breast examination, mammography, osteoporosis prevention, bone density scans, and recommendations for a calcium-rich diet, calcium supplementation, hormone replacement therapy, biphosphonates and raloxifen. On a logistic regression model the level of knowledge of the Hebrew language, age, ethnicity and not visiting the gynecologist were significantly related to not having received any preventive medicine recommendations.
Conclusions: Differences in cultural backgrounds and language between physicians and their patients may become barriers in the performance of screening and preventive medicine. Recognizing this potential for inequity and using methods to overcome these barriers may prevent it in the future

Background: The global spread of tuberculosis necessitates the development of an effective vaccine and new treatment modalities. That requires a better understanding of the differences in regulation of the immune responses to Mycobacterium tuberculosis between individuals who are susceptible or resistant to the infection. Previous immune studies in young Ethiopian immigrants to Israel did not demonstrate anergy to purified protein derivative or a Th2-like cytokine profile.

Objectives: To evaluate the profile of Th1 and Th2 cytokine production in immigrant TB patients, in comparison with asymptomatic control subjects.

Methods: The present study included (part 1): 39 patients with acute TB[1] (group 1), 34 patients with chronic relapsing TB (group 2), 39 Mantoux-positive asymptomatic TB contacts (group 3), and 21 Mantoux-negative asymptomatic controls (group 4). Patients were mainly immigrants from Eastern Europe and Ethiopia. Levels of interferon gamma, interleukin 2 receptor, IL-6[2] and IL-10 were measured in serum and in non-stimulated and PPD[3]-stimulated peripheral blood mononuclear cell culture supernatants, using commercial ELISA kits. In addition (part 2), levels of IFNg[4] and IL-12p40 were evaluated in 31 immigrant Ethiopian patients and 58 contact family members.

Results: Patients with acute disease tended to secrete more cytokines than contacts, and contacts more than chronic patients and controls, without a specific bias. None of the patients showed in vitro anergy. Discriminant probability analysis showed that from the total of 12 available parameters, a cluster of 6 (IFNg-SER[5], IFNg-PPD, IL-2R[6]-SER, IL-10-SER, IL-10-NS[7] and IL-6-PPD) predicted an 84% probability to become a TB contact upon exposure, 71% a chronic TB patient and 61% an acute TB patient. Family-specific patterns of IFNg were demonstrated in the second part of the study.

Conclusions: Firstly, no deficiency in cytokine production was demonstrated in TB patients. Secondly, acute TB patients secreted more cytokines than contacts, and contacts more than unexposed controls. Thus, neither anergy nor a cytokine dysregulation explains susceptibility to acute TB disease in our cohort, although chronic TB patients produced less cytokines than did acute patients and less than asymptomatic contacts. Thirdly, a certain cytokine configuration may predict a trend of susceptibility to acquire, or not acquire, clinical TB. It is presently unclear whether this finding may explain the disease spread in large populations. Finally, the familial association of IFNg secretion levels probably points towards a genetic regulation of the immune response to Mycobacterium tuberculosis.
