Background: During the last decade, Israel, a country with low tuberculosis rates, absorbed some 900,000 new immigrants from TB[1]-endemic countries.

Objectives: To analyze the specific impact of our screening procedures on active TB among children in Israel.

Methods: We conducted a retrospective analysis of epidemiologic and clinical data of all children (aged 0–17) with TB notified to the Ministry of Health between 1990 and 1999.

Results: There were 479 children with TB (male/female ratio 1.36). Most cases (81.8%) were foreign born, predominantly (88.2%) immigrants from Ethiopia and, therefore, huge differences existed in TB incidence rates according to countries of origin. Some 80% were diagnosed within 3 years of arrival, mainly due to active case-finding. Pulmonary TB, with infiltrates on chest X-ray, was found in 49.5%. Extra-pulmonary TB sites were: intra-thoracic lymphadenitis (31.1%), extra-thoracic lymphadenitis (12.5%), bones (3.6%), pleura (1.3%), meninges (1%), and others (1%). Seventy percent had a tuberculin skin test reaction ≥10 mm in size. Two (non-immigrant) children died of TB meningitis.

Conclusions: Most of the pediatric TB cases occurred in recent immigrants and were diagnosed within 3 years of immigration. These data support our policy of active case-finding among new immigrants from Ethiopia and extensive contact evaluation for all TB cases.

Intravenous immunoglobulins have been used as therapeutic proteins since the early 1980s.

Background: In the last decade there has been an increase in asthma morbidity. Hospital admission rates for childhood asthma are influenced by the prevalence of asthma and the quality of asthma care.

Objective: To assess trends in hospital admission and readmission rates for childhood asthma in the Jezreel Valley in Israel in the last decade, and to evaluate the possible effect of changes in asthma treatment upon hospitalization for acute asthma during this period.

Methods: All records from pediatric patients from the central hospital in the Jezreel Valley in northeastern Israel over a 10 year period from 1990 through 1999 who were diagnosed as having asthma were thoroughly reviewed and analyzed for admissions, re-admissions, and treatment before and during admissions

Results: There were 1584 admissions, 1208 were first-time admissions and 374 were re-admissions. The number of first-time admissions increased significantly over time (P < 0.0001), with a significant decrease of re-admissions (P < 0.005); this finding was more significant in children under the age of 8 years (P < 0.005). The length of hospital stay decreased significantly from 3.3 days to 2.7 days (P < 0.002). Significant changes in the use of medications included an increase in inhalant glucocorticoids and a decrease in the use of sodium cromoglycate and theophylline. Controller medication use was concomitant with a significant decrease in the re-admission rates.

Conclusions: The increase in the admission rate and the decrease in the rate of re-admissions and the length of hospital stay probably reflect the increase in the prevalence of asthma and changes in its treatment, respectively. It is essential that asthma be recognized as a significant cause of morbidity and that controller medications be administered to decrease the asthma's severity, morbidity, and resultant hospital admissions.
 

Background: Since 1984, several waves of Ethiopian immigrants have settled in Israel. On arrival they were found to be highly infected with intestinal parasites and to have increased serum immunoglobulin E and eosinophilia. 

Objectives: To study serum IgE [1] levels in Ethiopian children growing up in the environment of Israel . 

Methods: We assessed four groups of children of Ethiopian origin: a) adolescents examined on their arrival to Israel (group 1, n=11); b) adolescents born in Ethiopia and living in Israel for more than 7 years (group 2, n=10); c) children of Ethiopian origin born in Israel, without a history of allergy or asthma (group 3, n=15); and d) asthmatic children of Ethiopian origin born in Israel (group 4, n=8). A thorough clinical interview and examination as well as serum IgE levels, stool parasites and absolute eosinophil count were performed. 

Results: Group 1 (11 newly arrived Ethiopian adolescents) had a mean eosinophil count of 688 cells/ml (0–1739) and a mean serum IgE of 1043 IU/ml (253–2932), P < 0.0009 as compared to group 2. Helminthic parasites were observed in 8/11 individuals; after 1 year of follow-up and anti-parasitic treatment, serum IgE levels did not change significantly. Group 2 (10 Ethiopian born adolescents living in Israel for on average 10 years, 7–15 years) had a normal leukocyte count, MEC [2] 192 cells/ml (range 54–289), serum IgE 142 IU/ml (range 14–399 IU/ml) and no parasites in stool. Group 3 (15 Ethiopian children born in Israel) had a normal leukocyte count, MEC 128 cells/ml (0–324), serum IgE 55 IU/ml (7–189 IU/ml), similar to age-matched Israeli controls. In group 4 (8 Israeli born children of Ethiopian descent diagnosed with asthma), serum IgE showed significant elevation compared to Israeli age-matched asthmatic children (P < 0.005).  

Conclusions: High levels of IgE found in Ethiopian children on arrival to Israel declined to Israeli control levels after several years of living in the new environment. Ethiopian children born in Israel had normal levels of IgE, suggesting that environment is the main factor affecting IgE levels in this population. Israeli born Ethiopian children with asthma had significantly increased serum IgE levels compared to asthmatics of Israeli origin. These findings suggest that both environmental and genetic factors determine the level of serum IgE in these children.

Background: Chlorpromazine is a dopamine-receptor antagonist antipsychotic agent. Because of its strong alpha-blocking and sedative actions, it has also been used as emergency therapy for extreme arterial hypertension. Published reports to date have included very small numbers of patients (i.e., 5–30).

Objectives: To analyze data on almost 500 patients who received intravenous chlorpromazine for the emergency treatment of uncontrolled symptomatic hypertension in the pre-hospital setting.

Methods: We reviewed data from 496 consecutive patients who received intravenous chlorpromazine as emergency therapy for uncontrolled symptomatic hypertension. Chlorpromazine was injected intravenously. The dose was 1 mg every 2–5 minutes until the systolic pressure was -<140 mmHg and the diastolic pressure -<100 mmHg with alleviation of symptoms.

Results: The mean dose of chlorpromazine administered was 4.5 +- 5 mg (range 1–50 mg). Only 33 patients (7%) required >10 mg. Chlorpromazine reduced the systolic blood pressure from 222.82 +- 26.31 to 164.93 +- 22.66 mmHg (P < 0.001) and the diastolic blood pressure from 113.5 +- 16.63 to 85.83 +- 11.61 mmHg (P < 0.001). The sinus rate decreased from 97.9 +- 23.5 to 92.2 +- 19.7 beats per minute (P < 0.001). These results were achieved within the first 37 +- 11 minutes.

Conclusions: Intravenous chlorpromazine is safe and effective when used as emergency treatment for uncontrolled symptomatic hypertension.

Objective: To assess the effect of establishing a new dedicated acute stroke unit within a department of neurology on indicators of process of care and outcome of acute stroke in a routine clinical setting in Israel.

Methods: Stroke patients admitted to the Sheba Medical Center during the period March 2001 to June 2002 were included in a prospective study according to selection criteria. Data on demographics, risk factors, co-morbidities and stroke severity were collected. Indicators of process of care and outcome were assessed at hospital discharge and 30 days follow-up. Comparison between outcome variables by hospitalization ward was conducted using logistic regression analysis adjusting for confounders.

Results: Of 616 acute stroke patients (mean age 70 years, 61% men, 84% ischemic stroke), 353 (57%) were admitted to general wards and 263 (43%) to the stroke unit. Diagnostic procedures were performed more often, and infection rate was lower in the setting of the stroke unit. Poor outcome (modified Rankin scale ≥3 or death) was present less often in patients managed in the stroke unit both at hospital discharge (adjusted odds ratio 0.5, 95% confidence interval 0.3–0.8) and at 30 day follow-up (adjusted OR[1] 0.6, 95%CI[2] 0.3–0.9). A Functional Independence Measure score ≤90 or death at 30 day follow-up was less frequent among patients managed in the stroke unit than in general wards (adjusted OR 0.5, 95%CI 0.2–0.8).

Conclusions: Improved outcomes and higher adherence to guidelines were observed in patients treated in a stroke unit within a department of neurology. The results suggest that patients with acute stroke should have access to treatment in a dedicated stroke unit.

Objectives: To establish the impact of breast MRI on women undergoing testing in our institution.

Methods: We analyzed 82 cases that underwent MRI between January 2001 and April 2003. Analysis appraised the clinical impact of MRI testing in cases where medical summaries were available.

Results: Studies were categorized into five indications: a) screening in high risk women (n=7), b) search for primary disease in the presence of disease (n=5), c) monitoring of chemotherapy (n=2), d) postoperative assessment of tumor bed (n=9), and e) diagnostic/characterization of primary or recurrent breast cancer (n=59). Results were defined as negative, positive or no impact on clinical management. MRI testing had a positive impact in 62 cases, affecting measurable change in 9 cases. Benefit was seen in screening, diagnosis and postoperative cases. In 15 cases, MRI stimulated investigations.

Conclusion: MRI is a valuable tool in breast imaging and affects management. Further trials are necessary to define clearly the role of MRI and to ascertain whether in cases where beneficial impact on management is noted, there is ultimate impact on outcome. 

Objectives: To evaluate trends in the incidence of hip fractures in this population.

Methods: The study was based on two surveys done approximately 20 years apart. It included women and men 50 years and older with radiographic evidence of a new hip fracture caused by low impact trauma. Only fractures that resulted from low or moderate trauma were considered for the current study. Incidence rates were calculated based on population data obtained from the official Central Bureau of Statistics.

Results: There was an overall twofold increase in the incidence rate of hip fractures. However, this increase occurred almost exclusively in the over-75 year old age groups (2.5-fold increase, both in women and men). The mean (and median) age of patients with hip fractures increased significantly over the study period, corresponding with the increase in longevity between the two periods.

Conclusions: There was a marked secular increase in the incidence of proximal hip fractures in both genders, primarily because of an increase in the fracture rate in the very old. The increase in median age of fracture patients suggests that the observed increase in fracture rate can be attributed mainly to aging of the population rather than to deterioration in bone quality over the generations.

Adjustment disorder is a common diagnosis in psychiatric settings and carries a significant rate of morbidity and mortality. However, both current and previous diagnostic criteria are vague and lead to many difficulties in terms of validity and reliability. This review is based on a thorough literature search and a systematic evaluation of the empiric and theoretic data. The various pitfalls inherent in the process of diagnosing this disorder are discussed in light of the diagnostic criteria for the disorder.

Objectives: To report our experience in the treatment of pelvic fractures.

Methods: Between October 1998 and September 2001, 78 patients with pelvic fractures were admitted to our hospital. The age range of the 56 male and 22 female patients was 16–92 (mean 42 years). The cause of injury was road accident in 52 patients, fall from a height in 15, a simple fall in 9, and gunshot wounds in 2 patients. The Glascow Coma Scale score on arrival at the hospital was 3–15 (average 12). Twenty-five patients (32%) were admitted to the intensive care unit, 38 (48%) to the orthopedic department, 5 (6.4%) to neurosurgery and the remainder to a surgical department.

Results: Twenty-six patients (33.3%) received blood transfusion in the first 24 hours. Of the 25 patients (32%) with associated head trauma, 6 had intracranial bleeding; 29 patients (37%) had associated chest trauma, 28 (35.9%) had associated abdominal trauma, 16 (20.5%) had vertebral fractures and 40 (51.2%) had associated limb fractures. Pelvic angiography was performed in 5 patients (6.4%), and computed tomography-angiography of the cervical arteries and chest was performed in 1 and 5 patients respectively. Overall, a CT scan was performed in 56 patients (71.8%), of whom 25 (32%) had a pelvic CT on admission. Injury Severity Score was 4–66 (median 20). Laparotomy was performed in 14 patients (18%), spinal fusion in 5 (6.4%), limb surgery in 16 (20.5%), cranial surgery in 4 (5.02%), pelvic surgery in 10 (12.8%), chest surgery in 3 (3.85%), and facial surgery in 2 patients (2.56%). Seven patients (9%) died during the course of treatment.

Conclusion: Pelvic fracture carries a high morbidity rate. Associated chest, abdomen and limb injuries are often encountered. A multidisciplinary approach is needed to improve survival and outcome in patients with pelvic fractures. 

Objectives: To determine the effectiveness of a neuroreflexology-based screening test, specifically the Medex device (Medex Screen Ltd.), for diagnosing patients undergoing conventional internal organ assessment, in a hospital setting.

Methods: Patients admitted to an internal medicine department, who met the inclusion criteria and agreed to participate, underwent conventional medical evaluation that included past medical history and physical examination. Another examination was conducted by a second physician using the Medex device to determine internal organ pathologies. A third researcher compared the actual “conventional” diagnosis with the Medex device output using standard statistical analysis.   

Results: Overall, 150 patients participated in the study. Correlation was significant for all categories (P < 0.01) except for blood and lymphatic disease. A high sensitivity (>70%) was measured for cardiovascular, respiratory, gastrointestinal and genitourinary diseases. The highest measure of agreement, as represented by the Cohen-Kappa factor, was found for respiratory disease (0.57).

Conclusions: Although the exact mechanism is not entirely clear, measurement of electroskin impedance of dermal-visceral zones has the potential to serve as a screening tool for inner organ pathologies. Further research should be conducted to create more evidence to support or dispute the use of this technique as a reliable diagnostic tool.
