Aggravation of experimental cutaneous leishmaniasis in mice by administration of interleukin 3 总被引:7,自引:0,他引:7

Previous studies from our laboratory have shown that some in vitro maintained Leishmania major-specific L3T4+ T cells were capable of exacerbating cutaneous leishmaniasis after adoptive transfer to normal syngeneic mice. Results presented in this report show that these cells released substantial amounts of interleukin 3 (IL 3) and granulocyte-macrophage colony-stimulating factors after specific stimulation in vitro. In order to assess the involvement of such lymphokines in the exacerbation of cutaneous leishmaniasis by these L3T4+ T cells, the effect of the administration of important doses of IL 3 on the course of infection with L. major was investigated. The treatment of genetically susceptible BALB/c mice with IL 3 resulted in an enhancement of the size of lesions and favored the multiplication of parasites at anatomical sites distant from the primary lesion. Although IL 3 did not modify the development of lesions in genetically resistant CBA mice, this lymphokine promoted the growth of Leishmania in lymph node draining the lesion. Finally, the addition of IL 3 to macrophages parasitized in vitro enhanced the survival of intracellular Leishmania major. 相似文献

This case report deals with a patient who presented with a rapidly progressive myelopathy due to an intracranial dural arteriovenous fistula with perimedullar drainage (type V). We shall discuss the main clinical and radiological features of this type of fistula and its treatment from a review of the published cases. 相似文献

PURPOSE OF THIS REVIEW: To conduct a critical review of recent studies on the clinical and therapeutic aspects of multifocal motor neuropathy, and to analyse their implications for patient management. RECENT FINDINGS: Recent studies have contributed to defining the specific position of multifocal motor neuropathy within the spectrum of chronic immune-mediated polyneuropathies. One study compared features of this condition with multifocal acquired demyelinating sensory and motor neuropathy, while others have focused on pathological alterations at the site of conduction blocks. A further study described six new cases of multifocal acquired motor neuropathy, which should be considered as a variant of multifocal motor neuropathy. Several Cochrane reviews and review articles have shown evidence of the efficacy of intravenous immunoglobulins in the treatment of multifocal motor neuropathy. The issue of long-term intravenous immunoglobulins in multifocal motor neuropathy, however, has yielded controversial results. Two studies have shown progressive motor deterioration in most patients, correlated with electrophysiological signs indicative of axonal degeneration, while a third study found signs of sustained clinical and electrophysiological improvement after a mean follow up of 7.25 years. SUMMARY: Multifocal motor neuropathy is a distinct clinical entity that differs from chronic inflammatory demyelinating polyradiculoneuropathy and multifocal acquired demyelinating sensory and motor neuropathy, although they share some electrophysiological characteristics. Although the aetiology remains unsolved, frequent association with high-titer antibodies against ganglioside GM1, together with an often positive response to intravenous immunoglobulins further support an autoimmune mechanism. New therapeutic strategies are required, however, that focus on the effects and the costs of treatment over long-term follow up. 相似文献

Combined benign odontogenic tumors: CT and MR findings and histomorphologic evaluation 总被引:1,自引:0,他引:1

SUMMARY: Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma. 相似文献

Very Long-Chain Acyl-CoA dehydrogenase (VLCAD) deficiency is an inborn error of mitochondrial long-chain fatty acid oxidation (FAO) most often occurring in childhood with cardiac or liver involvement, but rhabdomyolysis attacks have also been reported in adults. We report in this study the clinical, biochemical and molecular studies in 13 adult patients from 10 different families with VLCAD deficiency. The enzyme defect was demonstrated in cultured skin fibroblasts or lymphocytes. All patients exhibited exercise intolerance and recurrent rhabdomyolysis episodes, which were generally triggered by strenuous exercise, fasting, cold or fever (mean age at onset: 10 years). Inaugural life-threatening general manifestations also occurred before the age of 3 years in four patients. Increased levels of long-chain acylcarnitines with tetradecenoylcarnitine (C14:1) as the most prominent species were observed in all patients. Muscle biopsies showed a mild lipidosis in four patients. For all patients but two, molecular analysis showed homozygous (4 patients) or compound heterozygous genotype (7 patients). For the two remaining patients, only one mutation in a heterozygous state was detected. This study confirms that VLCAD deficiency, although being less frequent than CPT II deficiency, should be systematically considered in the differential diagnosis of exercise-induced rhabdomyolysis. Measurement of fasting blood acylcarnitines by tandem mass spectrometry allows accurate biochemical diagnosis and should therefore be performed in all patients presenting with unexplained muscle exercise intolerance or rhabdomyolysis. 相似文献

Calcified sphenoid mucocele 总被引:1,自引:0,他引:1
Sphenoid sinus mucoceles are uncommon lesions, and may rarely contain calcifications within their wall. We describe a new appearance of this lesion--sphenoid sinus mucocele with gross calcifications within its matrix. 相似文献
