11/2677. Extracorporeal photochemotherapy in human and murine graft-versus-host disease.Extracorporeal photochemotherapy (ECP) is an immunotherapy that has found a role in the therapy of cutaneous T cell lymphoma, a disease of mature activated T cells. Graft-versus-host disease (GVHD) is also mediated by activated T cells, and thus often responds to therapies that target T cells. Murine models for both GVHD and ECP can be combined to study the impact of this immunotherapy on GVHD. In this paper we present a patient with GVHD who demonstrated a beneficial therapeutic response to treatment with ECP. The findings of this case are compared with the observations from a murine model for GVHD-ECP. The potential mechanisms of ECP in the treatment of GVHD are discussed. along with the similarities observed with ECP in the treatment of other conditions.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
12/2677. A case report of neutrophilic eccrine hidradenitis in a patient receiving chemotherapy for acute myeloid leukaemia.Neutrophilic eccrine hidradenitis (NEH) is a neutrophilic dermatosis primarily affecting the eccrine glands and occurs in patients undergoing chemotherapy. It must be distinguished from infections, drug eruptions, leukaemia cutis or other forms of skin diseases. As it is self-limiting, establishing the diagnosis will avoid unnecessary treatment for infections or changes in drug therapy.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
13/2677. Apparent hemolysis in an AIDS patient receiving trimethoprim/sulfamethoxazole: case report and literature review.OBJECTIVE: To describe a case of acute hemolysis associated temporally with administration of trimethoprim/sulfamethoxazole (TMP/SMX) in a patient with AIDS, review the available literature on TMP/SMX-induced hemolytic anemia, and discuss possible drug- and disease-related factors that may have contributed to the episode of hemolysis. CASE SUMMARY: A precipitous decrease in red blood cell count, hemoglobin, and hematocrit occurred shortly after a black woman with AIDS received a single intravenous dose of TMP/SMX for pneumocystis carinii pneumonia. Following drug discontinuation and repeated transfusions, the patient's hematologic indices returned to baseline. literature SOURCES: References were obtained using medline searches, the bibliographies of articles identified during the searches, review articles, and standard textbooks. DATA SYNTHESIS: Of the two different mechanisms of TMP/SMX-induced hemolytic anemia, the reaction is most likely to occur via dose-related oxidative disruption of the erythrocyte membrane in subpopulations deficient in glucose-6-phosphate dehydrogenase (G6PD) activity. In the US, G6PD deficiency most frequently is encountered among blacks. The potential for hemolysis may be further increased in G6PD-deficient AIDS patients, who also appear to lack adequate intracellular glutathione, which is essential for protecting the erythrocyte membrane from oxidative damage. Although an assay for G6PD activity was not conducted, the case circumstances were consistent with TMP/SMX-induced hemolysis in a G6PD-deficient patient. CONCLUSIONS: Black patients with AIDS who are receiving relatively high (greater than or equal to 50 mg/kg/d) dosages of TMP/SMX should be monitored closely for signs and symptoms of hemolytic anemia.- - - - - - - - - - ranking = 3keywords = ms (Clic here for more details about this article) |
14/2677. lymphangioma circumscriptum of the tongue.A case is reported of severe transient macroglossia after biopsy from the tongue in a 13-year-old boy who has had intermittent macroglossia since the age of 1 year as a result of extensive lymphangioma circumscriptum of the tongue. The acute lesions appear to result from haemorrhage into the lymphatic spaces following rupture of blood vessels in connective tissue septa and possibly secondary infection.- - - - - - - - - - ranking = 5keywords = ms (Clic here for more details about this article) |
15/2677. Acute hemorrhagic leukoencephalitis in patients with acute myeloid leukemia in hematologic complete remission.The authors describe the cases of three patients affected by acute myeloid leukemia, in complete remission, who rapidly developed neurologic symptoms leading to death. Neither clinical characteristics, nor radiological or microbiological procedures, allowed an etiological diagnosis of the neurologic syndrome. Post-mortem examination of the brain showed both macroscopic and microscopic findings compatible with acute hemorrhagic leukoencephalitis. The difficulty in distinguishing this entity from other CNS disease-related complications (e.g. leukemia infiltration, drug toxicity, hemorrhages) should not lead to an underestimation of the true incidence of this complication. We believe that with more attention to the possibility of this complication there would probably be both a greater possibility of collecting clinical informations about the real impact of this dramatic disease and a stronger hope of finding the right treatment for it.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
16/2677. Ischaemic enterocolitis complicating idiopathic dysautonomia.A previously fit 23 year old adult male who presented with a sudden onset of profound autonomic neuropathy, for which no cause could be found, is described. The patient subsequently developed ischaemic enterocolitis that ultimately necessitated colectomy and subtotal enterectomy. Potential neural and humoral mechanisms are discussed.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
17/2677. Acute infection with trichophyton rubrum associated with flares of atopic dermatitis.trichophyton rubrum has been implicated as a potential trigger in flares of atopic dermatitis. We describe a patient with atopic dermatitis who presented with a history of multiple flares and concurrent acute tinea pedis and onychomycosis. Symptoms of atopic dermatitis and culture-positive acute infection with T. rubrum resolved during each flare using systemic antifungals. Flares of atopic dermatitis may be triggered by acute T. rubrum infections. Antifungal therapy should be considered in these patients.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
18/2677. Acute hepatitis after riluzole administration.riluzole is a new drug representing the first active treatment for amyotrophic lateral sclerosis. We report the cases of two patients who developed acute hepatitis after taking riluzole at the recommended dose (100 mg daily) for 7 and 4 weeks, respectively. In both cases, liver histology showed hepatocellular damage with inflammatory infiltration and microvesicular steatosis without fibrosis. liver enzymes returned to normal 4 and 8 weeks, respectively, after riluzole withdrawal. In one case, the readministration of riluzole was followed by the relapse of hepatitis. These two observations strongly suggest that riluzole can induce acute hepatitis with associated hepatocellular damage and microvesicular steatosis. They also suggest that liver enzymes should be monitored during treatment with riluzole.- - - - - - - - - - ranking = 220.73304984577keywords = sclerosis (Clic here for more details about this article) |
19/2677. Computed tomography and pathologic findings in fulminant forms of idiopathic interstitial pneumonia.This study describes the computed tomography features of various fulminant forms of idiopathic interstitial pneumonia and to clarify the usefulness of computed tomography in such patients. Computed tomography scans in 19 patients with fulminant forms of idiopathic interstitial pneumonia were reviewed. This study included patients with acute interstitial pneumonia (n = 7), an accelerated form of idiopathic pulmonary fibrosis (n = 2), and an acute exacerbation of idiopathic pulmonary fibrosis (n = 10). Pathologic confirmation of the diagnosis was obtained in all patients. Follow-up computed tomography scans were available for eight patients, and postmortem computed tomography scans were available for three patients. All patients had progressive ground-glass attenuation, consolidation, or both. In patients with an acute exacerbation of idiopathic pulmonary fibrosis, subpleural honeycombing was also seen. Follow-up computed tomography showed a change from ground-glass attenuation to consolidation with distortion. Architectural distortion, traction bronchiectasis, and ground-glass opacity were the prominent features in the initial computed tomography scans obtained more than 7 days after the onset of symptoms, and cystic lesions were seen in follow-up computed tomography obtained more than 1 month after the onset. High-resolution computed tomography was more sensitive than the plain radiographs in the early detection of these entities. Computed tomography examination at the onset of the acute symptoms is useful in classifying these fulminant forms of idiopathic interstitial pneumonia.- - - - - - - - - - ranking = 9keywords = ms (Clic here for more details about this article) |
20/2677. Extremely acute phenytoin-induced peripheral neuropathy.PURPOSE: Peripheral neuropathy is a rare adverse effect associated with phenytoin (PHT), and it usually occurs after the prolonged use of PHT. Acute PHT-induced peripheral neuropathy is extremely rare. methods: An 18-year-old girl was admitted for the control of epilepsy. Just a few hours after the administration of PHT, she complained of distal lower-extremity paresthesia in a stocking distribution and motor weakness: the achilles tendon reflex was absent. RESULTS: Electrophysiological studies revealed slightly reduced sensory-conduction velocity and mild prolongation of distal latency in the lower extremities. After the discontinuation of PHT, these symptoms disappeared gradually, and sensory-conduction velocity and distal latency became normal. CONCLUSIONS: Although it has been reported that peripheral neuropathy occurred after treatment with PHT for a week, there has been no report of a patient such as ours, who developed peripheral neuropathy just a few hours after the initial administration of PHT. The underlying mechanism remains unknown; however, we should pay attention to such extremely acute peripheral neuropathy when using PHT.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
