Intraarterial multi-modal reperfusion therapy for acute ischemic stroke: a10 year single-center experience.

Background: Only 0.5% of stroke patients in Israel are treated with endovascular multi-modal reperfusion therapy (MMRT) each year.

Objectives: To assess our experience with MMRT over the last decade.

Contribution of animal models to the research of the causes of diabetes.

In most publications, animal models of diabetes have mainly been investigated for their multiple etiologies as well as for changes leading to diabetes and their genetic derivation. Aspects which seem important and need a special research endeavor are the mechanism of the causes of diabetes and the lapse into complications in different species, their molecular basis and possible arrest and prevention. A concise list and and short discussion of the intensively studied rodents is presented of spontaneous or nutritional background causing Type 2 diabetes but omitting diabetes evoked by transgenic manipulations or gene knockout techniques.

Lung function response to bronchodilator nebulization via hood in wheezy infants: a pilot study.

Background: In infants, small volume nebulizers with a face mask are commonly used to facilitate aerosol therapy. However, infants may be disturbed by mask application, causing poor mask-to-face seal and thus reducing the dose delivered.

Objectives: To compare lung function response to bronchodilator nebulization via two delivery devices: hood versus mask.

Acetylcholinesterase inhibitors and cholinergic modulation in Myasthenia Gravis and neuroinflammation.

The cholinergic network affects various cellular functions including neurotransmission, and immune reactions. In Myasthenia Gravis (MG), diagnosis and symptomatic therapy are based on cholinergic modulation by acetylcholinesterase inhibitors (AChEI). In Alzheimer's disease (AD) a neurodegenerative disorder associated with inflammatory pathology, cholinergic systems cell loss occurs early.

Use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in patients with congestive heart failure: an observational study of treatment rates and clinical outcome.

Background: Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers improve prognosis in congestive heart failure and are the treatment of choice in these patients. Despite this, the rates of ACE-I usage in heart failure patients remain low in clinical practice.

Objectives: To evaluate the rate of ACE-I/ARB treatment in hospitalized patients with CHF, and analyze the reasons for non-treatment.

Canal expansive laminoplasty in the management of cervical spondylotic myelopathy.

Background: Cervical spondylotic myelopathy is often progressive and leads to motor and sensory impairments in the arms and legs. Canal expansive laminoplasty was initially described in Japan as an alternative to the traditional laminectomy approach. The results of this approach have not previously been described in the Israeli population.

Long-term results of "chemical sphincterotomy" for chronic anal fissure: a prospective study.

Introduction: Pharmacologic anal sphincter relaxants promote fissure healing; however, their effect is transient and the risk of late recurrence remains uncertain.

Methods: From August 1997 to August 2002, patients with chronic anal fissure attending our outpatient clinic were treated with a protocol that included: topical isosorbide dinitrate, 2.5 mg, or nifedipine, 0.

Clozapine-induced systemic lupus erythematosus.

Objective: To report a case of classic clozapine-induced systemic lupus erythematosus that also developed on rechallenge.

Case Summary: A 32-year-old white woman diagnosed with schizophrenia presented in 1996 with clinical characteristics and laboratory markers consistent with drug-induced lupus (DIL). Clozapine, started 1 year prior, was withdrawn, with complete biological and clinical remission within 3 months.

Stimulated-single fiber electromyography monitoring of anti-sense induced changes in experimental autoimmune myasthenia gravis.

The neuromuscular weakness associated with myasthenia gravis (MG) can be transiently relieved by pharmacological inhibitors of acetylcholinesterase (AChE). Here, we expand the anticholinesterase repertoire to include 2'-O-methyl-protected antisense oligonucleotides targeted to AChE mRNA (EN101). Using stimulated-single fiber electromyography, we show that EN101 treatment of rats with experimental autoimmune myasthenia gravis (EAMG), improved the mean consecutive difference (MCD) and blocking for 24h.

LRP and alphavbeta3 mediate tPA activation of smooth muscle cells.

Tissue-type plasminogen activator (tPA) regulates vascular contractility through the low-density lipoprotein-related receptor (LRP), and this effect is inhibited by plasminogen activator inhibitor type 1 (PAI-1). We now report that tPA-mediated vasocontraction also requires the integrin alphavbeta3. tPA-induced contraction of rat aortic rings is inhibited by the Arg-Gly-Asp (RGD) peptide and by monoclonal anti-alphavbeta3 antibody.

Effect of IL-2-Bax, a novel interleukin-2-receptor-targeted chimeric protein, on bleomycin lung injury.

The role of lymphocytes in the pathogenesis of lung fibrosis is not clear, but the weight of the evidence supports a pro-fibrotic effect for lymphocytes. The high-affinity interleukin-2 receptor (haIL-2R) is expressed on activated, but not quiescent, T lymphocytes. This selective expression of haIL-2R provides the basis for therapeutic strategies that target IL-2R-expressing cells.

Is clinical wheezing reliable as the endpoint for bronchial challenges in preschool children?

The present study was designed to compare the clinical finding of wheeze by auscultation with an objective evaluation by acoustic means at the endpoint of a bronchial challenge in preschool children. Challenges were undertaken using a tidal breathing method in 51 preschool children as part of the investigation of possible asthma. An electronic stethoscope was used for auscultation of each lung and for the simultaneous recording of the acoustic sonogram for analysis.

Involvement of endogeneous glutamate in the stimulatory effect of norepinephrine and serotonin on the hypothalamo-pituitary-adrenocortical axis.

The effects of ionotropic glutamate receptor antagonists on the pituitary adrenal responses following injections of norepinephrine (NE) and serotonin (5-HT) receptor agonists into the hypothalamic paraventricular nucleus (PVN) or electrical stimulation of central NE and 5-HT pathways were studied in anesthetized male rats. PVN injections of an alpha(1)-adrenergic receptor agonist or a serotonergic 5-HT(1A) receptor agonist markedly increased both adrenocorticotropin (ACTH) and corticosterone (CS) serum levels. These responses were significantly inhibited by separate pre-injection of the selective non-NMDA and NMDA glutamate receptor subtype antagonists into the PVN in a dose-dependent manner.

Extracellular phospholipase A2 inhibitors suppress central nervous system inflammation.

Phospholipase A2 (PLA2) plays a key role in the production of proinflammatory mediators, namely the arachidonic acid-derived eicosanoids, lysophospholipids, and platelet-activating factor, and indirectly influences the generation of cytokines, nitric oxide (NO), and free radicals. Accordingly, regulation of its activity is important in the treatment of inflammation. Since the main site of PLA2 action in inflammatory processes is the cell membrane, we synthesized extracellular PLA2 inhibitors (ExPLIs) composed of N-derivatized phosphatidyl-ethanolamine linked to polymeric carriers.

Disseminated Mycobacterium kansasii infection with pulmonary alveolar proteinosis in a patient with chronic myelogenous leukemia.

A 64-year-old woman with chronic myelogenous leukemia (CML) was admitted due to prolonged fever and lung infiltrates. An open lung biopsy was required to make the diagnosis of pulmonary alveolar proteinosis (PAP) and infection with Mycobacterium kansasii. She was treated successfully with combined antimycobacterial therapy for 14 months.

Onchocerciasis among Ethiopian immigrants in Israel.

Background: Onchocerciasis results from infestation by the nematode Onchocerca volvulus, and is characterized clinically by troublesome itching, skin lesions and eye manifestations. Since 1992, approximately 9,000 immigrants have arrived in Israel from the Kuwara province of northwest Ethiopia where the prevalence of onchocerciasis is particularly high.

Objectives: To determine whether onchocerciasis is the cause of cutaneous and ocular symptoms among recent immigrants from the Kuwara province in Ethiopia.
