Background: Seborrheic dermatitis is a common chronic disease. Malassezia yeasts have been implicated in the pathogenesis of this disease. Antifungal agents are known to be effective in the treatment of Malassezia yeast infections.

Objectives To evaluate the efficacy of itraconazole in the treatment of mild to severe facial seborrheic dermatitis.

Methods: Sixty patients with moderate to severe seborrheic dermatitis were evaluated in an open non-comparative study. Patients were treated with oral itraconazole, initially 200 mg/day for a week, followed by a maintenance therapy of a single dose of 200 mg every 2 weeks. Four clinical parameters (erythema, scaling, burning, itching) were assessed using a 0–3 score. Mycological evaluation determined the presence of Malassezia spores in the scales using a direct smear.

Results: At the end of the initial treatment significant improvement was reported in three clinical parameters: erythema, scaling, itching. Maintenance therapy led to only slight further improvement. Burning sensation was only mildly improved during the treatment. The quantity of Malassezia spores present in the direct smear decreased throughout the treatment period. No blood test abnormalities were found during the treatment.

Conclusions: In this study initial treatment with itraconazole was beneficial in patients with moderate to severe seborrheic dermatitis.

Neonatal lupus erythematosus is an uncommon transplacentally Acquired Autoimmune Disorder. The most common clinical manifestations are skin rash, congenital atrioventricular block, thrombocytopenia, leucopenia, anemia, and hepatosplenomegaly. Usually, the skin rash resembles subacute cutaneous lupus, but different forms of rash have been reported in Neonatal lupus erythematosus and some are rare forms. NLE should be suspected in babies with atypical skin lesions, even if present at birth.  

Background: Idiopathic frozen shoulder is a self-limiting regional skeletal problem of unknown etiology. Clinically, patients first experience a phase of pain, progressing to a freezing stage when glenohumeral motion is lost, followed by a thawing phase when pain gradually subsides and most of the lost motion returns.

Objectives: To identify possible specific and non-specific risk factors for idiopathic frozen shoulder.

Methods: We compared the medical histories, drug treatment, previous hospital as well as health management organization blood tests of 126 new consecutive frozen shoulder patients from a shoulder clinic to those of an age-matched control group of 98 consecutive patients from an orthopedic foot and ankle clinic and to the regional population disease prevalence registry. Frozen shoulder was classified as idiopathic only if there was no history of trauma and no evidence of a rotator cuff tear.

Results: Among the frozen shoulder patients 29.4% had diabetes and 13.5% had thyroid disorders. The risk ratio for diabetes in the frozen shoulder group was 5.9 for males (95% confidence interval 4.1–8.4, P < 0.001) and 5.0 for females (95% CI[1] 3.3–7.5, P < 0.001). The risk ratio for thyroid disorders among females with frozen shoulder was 7.3 (95% CI 4.8–11.1, P = 0.001). No significant difference was found in the prevalence of thyroid disorders between frozen shoulder and the control group, but there was a significantly higher prevalence of diabetes in males and a trend for higher prevalence in females in the frozen shoulder group.

Conclusions: Physicians should be aware that diabetes is a specific risk factor for idiopathic frozen shoulder in both males and females and thyroid disorders are a non-specific risk factor in females only.  

Background: Balneotherapy is an established treatment modality for musculoskeletal disease. However, few studies have examined the efficacy of spa therapy in elderly patients with degenerative spine and joint diseases.

Objectives: To assess the effects of balneotherapy on chronic musculoskeletal pain, functional capacity, and quality of life in elderly patients with osteoarthritis of the knee or chronic low back pain.

Methods: A total of 81 patients enrolled and the results of 76 were analyzed. Subjects underwent a 1 day course of 30 minute daily baths in mineral water. Changes were evaluated in the following parameters:  pain intensity, functional capacity, quality of life, use of non-steroidal anti-inflammatory or analgesic drugs, subjective disease severity perceived by the patients, investigator-rated disease severity, and severity of pain perceived by the patients.

Results: Compared to baseline, all monitored parameters were significantly improved by balneotherapy in both investigated groups. Moreover, the favorable effect was prolonged for 3 months after treatment.

Conclusions: This study showed that balneotherapy is an effective treatment modality for elderly patients with osteoarthritis of the knee or with chronic low back pain, and its benefits last for at least 3 months after treatment.
 

Background: In contrast to the relative scarcity of donor kidneys and hearts, the potential supply of deceased donor pancreata is exceeding the demand. However, this potential organ surplus is not being fully realized because in current transplantation practice the duration of pancreas storage before transplantation is limited and many organs with established or anticipated cold ischemia time exceeding 8–10 hours are discarded owing to the extreme vulnerability of pancreatic tissue to anaerobic damage caused by preservation.

Objectives: To reduce cold ischemic injury in order to increase the utilization of donor pancreases in Israel for whole-organ and cell transplantation.

Methods: We evaluated a novel two-layer preservation oxygenated cold storage method that uses perfluorocarbon to continuously supply oxygen to the pancreas during preservation in conventional University of Wisconsin solution.

Results: Pancreatic tissue morphology, viability and adenosine-triphosphate content were serially examined during preservation of the pig pancreas for 24 hours either by a two-layer or by conventional simple cold storage. Already after 12 hours of storage, the superiority of the two-layer method over the University of Wisconsin method was apparent. Starting at this time point and continuing throughout the 24 hours of preservation, the tissue architecture, mitochondrial integrity, cellular viability and ATP[1] tissue concentration were improved in samples preserved in oxygenated UW[2]/PFC[3] as compared to controls stored in conventional UW solution alone.

Conclusions: The UW/PFC two-layer preservation method allowed tissue ATP synthesis and amelioration of cold ischemic tissue damage during extended 24 hour pancreas preservation. This method could be implemented in clinical practice to maximize utilization of pancreata for whole-organ and islet transplantation as well as for pancreas sharing with remote centers.

Background: Infliximab and etanercept have been included in the Israeli national list of health services since 2002 for rheumatoid arthritis and juvenile idiopathic arthritis, and since 2005 for psoriatic arthritis and ankylosing spondylitis. The regulator (Ministry of Health and health funds) mandates using fixed doses of infliximab as the first drug of choice and increased dosage is not allowed. For other indications (e.g., vasculitis), anti-tumor necrosis factor therapy is given on a "compassionate" basis in severe refractory disease.

Objectives: To describe our experience with anti-TNF[1] therapy in a single tertiary referral center in northern Israel and to analyze the impact of the national health policy on the results.

Methods: We reviewed the medical records of patients who received anti-TNF therapy in our institution, and analyzed demographic data, diagnosis, clinical and laboratory features, previous and current therapies, and anti-TNF treatment duration and side effects.

Results: Between 2001 and 2006, 200 patients received anti-TNF therapy for rheumatoid arthritis (n=108), juvenile idiopathic arthritis (n=11), psoriatic arthritis (n=37), ankylosing spondylitis (n=29), adult Still's disease (n=4), overlap disease (RA[2] and scleroderma or polymyositis, n=6), temporal arteritis (n=1), polyarteritis nodosa (n=1), dermatomyositis (n=1), amyloidosis secondary to RA (n=1) and Wegener's granulomatosis (n=1). Forty percent of RA patients discontinued the first anti-TNF agent due to side effects or insufficient response. Higher sedimentation rate and lower or negative rheumatoid factor predicted better response to therapy among RA patients. AS[3] and PS[4] patients had a better safety and efficacy profile. Severe infections occurred in 2% of patients. All eight patients who presented lung involvement as part of their primary rheumatic disease remained stable or improved. A significant improvement was achieved in all six patients with overlap disease.

Conclusion: Our daily practice data are generally in agreement with worldwide experience. The ‘deviations’ might be explained by the local health policy at that time. The impact of health policy and economic and administrative constraints should be taken into account when analyzing cohort daily practice data.

Background: Based on the outcome of several randomized controlled trials, the orally active leukotriene receptor antagonist montelukast (Singulair®, Merck) has been licensed for treatment of asthma. The drug is favored for treating childhood asthma, where a therapeutic challenge has arisen due to poor compliance with inhalation therapy.

Objectives: To assess the efficiency of and satisfaction with Singulair® in asthmatic children under real-life conditions.

Methods: Montelukast was prescribed for 6 weeks to a cohort of 506 children aged 2 to 18 years with mild to moderate persistent asthma, who were enrolled by 200 primary care pediatricians countrywide. Four clinical correlates of childhood asthma – wheeze, cough, difficulty in breathing, night awakening – were evaluated from patients' diary cards.

Results: Due to under-treatment by their physicians, almost 60% of the children were not receiving controller therapy at baseline. By the end of the study, which consisted of montelukast treatment, a significant improvement over baseline was noted in asthma symptoms and severity, as well as in treatment compliance. The participating pediatricians and parents were highly satisfied with the treatment.

Conclusions: The results of this extensive study show that the use of montelukast as monotherapy in children presenting with persistent asthma resulted in a highly satisfactory outcome for themselves, their parents and their physicians.
 

Mesenchymal stromal cells are multipotent cells capable of tissue repair and immune modulation. They are primarily found in bone marrow, but are also present in other tissues of mesenchymal origin, such as fatty tissue, muscle, tendons, etc. MSC[1] can easily be obtained by bone marrow aspiration, showing a rapid expansion in vitro. New protocols enable cell culture without the use of animal-derived sera and artificial growth factors. Avascular necroses of the bone may have different causes. AVN[2] in autoimmune and hematological diseases show a strong association with corticosteroid treatment, which is often unavoidable in severe cases. Until recently, core decompression of the affected osseous area was the standard approach. Because of their differentiation properties, easy accessibility and proliferative capacity, autologous MSCs could potentially complement AVN treatment by adding fresh “osteogenic cells” to the healing process.

Background: Regular physical activity is known to have a beneficial impact on multiple cardiovascular risk factors, but there is no routine provision of exercise training programs to patients after ischemic stroke.

Objectives: To assess the tolerability, safety and effect of an outpatient supervised exercise training program in patients after a non-disabling ischemic stroke.

Methods: Patients discharged home following a minor ischemic stroke (modified Rankin scale; mRS ≤ 2) were referred to a 3 month outpatient supervised exercise training program, performed twice weekly as prescribed by a physiologist and supervised by physical therapy. Exercise capacity was evaluated by the 6 minute walk test, and by the modified Bruce exercise test.

Results: Of the 52 patients who met the selection criteria, 43 underwent supervised exercise training within 2 months of stroke onset and 9 did not (control group). The baseline characteristics were comparable between the two groups. Following the exercise training program, an improvement in exercise capacity was observed manifested by improvement in the 6 minute walk test (444 ± 90 to 557 ± 99 meters in the exercise group vs. 438 ± 101 to 418 ± 126 in the control group; P = 0.002 for the score changes) and in the exercise duration achieved in the modified Bruce test and the metabolic equivalents achieved [9.6 ± 3.7 to 12.4 ± 3.2 minutes and 6.2 ± 2.8 to 8.5 ± 3.4 respectively in the exercise group (n=41) vs. 9.2 ± 3.5 to 8.0 ± 3.4 min and 5.8 ± 1.8 to 5.8 ± 2.8 in the control group (n=7); P = 0.0009 and 0.01 for score changes, respectively].

Conclusions: An outpatient supervised exercise training program after a minor ischemic stroke is feasible, well tolerated and is associated with improvement in exercise capacity. We strongly recommend that an aerobic exercise program be offered to suitable patients after an ischemic stroke.
 

Background: Many centers in Israel still use pre-1970 reference data for neonatal weight, length and head circumference. A recently published population-based reference overestimated the weight of premature infants.

Objective: To develop a national reference for birth weight, birth length, and head circumference by gestational age for singleton infants in Israel.

Methods: Data were collected on all singleton live births documented in the neonatal registry of Rabin Medical Center from 1991 to 2005 (n=82,066). Gestational age estimation was based on the last menstrual period until 1977 and early fetal ultrasound thereafter. Neonates with an implausible birth weight for gestational age (identified by the rule of median ± 5 standard deviations or expert clinical opinion) were excluded. Reference tables for fetal growth by gestational age were created for males and females separately.

Results: The growth references developed differed markedly from the Usher curves currently used in our department. Compared to the recently published population-based birth weight reference, our data were free of the problem of differential misclassification of birth weight for gestational age for the premature infants and very similar for the other gestational age groups. This finding reinforced the validity of our measurements of birth weight, as well as of birth length and head circumference.

Conclusions: Use of our new (birth length and head circumference) and improved (birth weight) gender-specific hospital-based reference for fetal growth may help to define normal and abnormal growth in the neonatal population of Israel and thereby improve neonatal care and public health comparisons.
