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

Although the airway granulomata in Wegener's granulomatosis were stressed initially by Friedrich Wegener himself, in the last few decades systemic lesions mainly caused by acute vasculitis have received the most attention. However, recently, the implication of granulomatous manifestations in WG[1] has raised much interest. The present data suggest that an aberrant Th1-type response might play a role in the initiation of WG, clinico-pathologically characterized by granulomatous inflammation rather than vasculitis. Disease progression to generalized WG with the predominance of vasculitic manifestations is associated with a “switch” or further complexity of the collective T cell response with the appearance of another subset of Th2-type cells and a less prominent Th1-type cytokine production in the granulomatous lesions of the upper respiratory tract. However, the clinical significance of the granulomatous inflammation is not yet completely understood. Further research will also have to focus on the role of the granulomata during relapsing disease. We review present knowledge of granulomatous inflammation in WG. Morphologic aspects, the scale of cytokine alterations as well as the variety of clinical manifestations are discussed.

Background: Dyspnea may be a presenting symptom of type I food hypersensitivity, and bronchial hyper-reactivity, without known asthma, can coexist in patients with food allergy.

Objective: To evaluate airway involvement in young adult patients with food allergy and no asthma and compare the findings to those of patients with food allergy and asthma, with food allergy and allergic rhinitis, with asthma and no food allergy, and of apparently healthy controls.

Methods: The evaluation involved prick skin test to food (65 allergens) and inhalants (24 allergens), spirometry, methacholine inhalation challenge, and induced sputum for cell analysis. The five groups consisted of 18 patients with food allergy alone, 11 with food allergy and asthma, 13 with food allergy and allergic rhinitis, 10 with asthma alone, and 10 controls.

Results: Patients with food allergy alone were mainly (86%) skin sensitive to pollens. Those with either asthma or allergic rhinitis were mainly (95%) sensitive to mites. BHR was detected in 40% of the patients with food allergy alone, 55% of the patients with allergic rhinitis, and 100% of the patients with asthma. Cell counts in the sputum of patients with asthma and in those with food allergy and asthma showed higher eosinophil counts compared to those with food allergy and allergic rhinitis. Patients with food allergy and no asthma, regardless of BHR status, had mainly neutrophils in the sputum.

Conclusions: Patients with food allergy are highly likely to have concomitant asymptomatic BHR. Mite sensitivity in patients with food allergy predicts respiratory allergy (either asthma or allergic rhinitis). High eosinophil levels in the sputum of food allergy patients predict respiratory involvement.

Non-steroidal anti-inflammatory drugs, mainly ibuprofen, are extensively used in children as analgesics and antipyretics.

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.

Objectives: To determine the overall prevalence of PBC[1] in southern Israel and the specific rates for different immigrant groups between January 1993 and October 2004.

Methods: Multiple case-finding methods were used to identify all cases of PBC in the study region. Age-adjusted prevalence rates were compared among the different immigrant groups.

Results: A total of 47 cases of PBC were identified with an overall prevalence of 55 cases per million. All patients were women, and all except for a Bedouin Arab were Jewish. Foreign-born patients comprised 70% of our PBC cohort even though they represent only 45.4% of the regional population. This predominance of immigrants did not change when the rates were adjusted for age (P < 0.001). The prevalence rates were 40, 177, and 58 cases per million for those born in Israel, North Africa or Asia, and Eastern Europe, respectively. The age-specific prevalence rate for women older than 40 years varied from 135 cases per million among those born in Israel to 450 among immigrants from Eastern Europe and the former USSR to 700 cases per million among immigrants from North Africa and Asia.

Conclusions: The prevalence of PBC in southern Israel is similar to that reported from some European countries. The rate is much higher among Jews than Arabs and among immigrants to Israel compared to native Israelis.

Objectives: To estimate self-medication with antibiotics by a population in northern Israel.

Methods: We sent by post a questionnaire on antibiotic usage to 2,615 adults, both Jewish and Arab, living in northern Israel.

Results: The overall response rate was low (17.9%), particularly among the Arab population (9.4% of respondents). Among the 467 respondents, 169 (36.2%) reported 215 antibiotic courses within the last year. Amoxicillin was the antibiotic most commonly used (32.7% of courses); 89.4% of antibiotics were obtained via a physician’s prescription; 114 respondents (24.4%) stored leftover antibiotics at home and 81 (18.7%) would consider self-medication with antibiotics without a medical consultation.

Conclusions: Our results show that over-the counter acquisition of antibiotics is rare in Israel. However, the storage of leftover antibiotics in the home constitutes an alternative potential source of self-medication that can have untoward consequences, not only for the individual patient but also for the general population since inappropriate antibiotic usage contributes to the increasing rates of antimicrobial resistance.

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.
