1/1600. central nervous system T-cell lymphoproliferative disorder in a patient with chronic active Epstein-Barr virus infection.PURPOSE: central nervous system (CNS)-T cell lymphoproliferative disorder (T-LPD) developing during the course of chronic active Epstein-Barr virus (CAEBV) infection is reported. patients AND methods: CAEBV was diagnosed in a 14-month-old boy with fever, cytopenia, hepatosplenomegaly, and abnormal high titers of anti-Epstein-Barr virus (EBV) antibodies. At 8 years of age, he had a splenectomy because of progressive disease. RESULTS: After 27 months of clinical remission, muscle weakness and paresthesia developed. magnetic resonance imaging of his brain showed spotty T2 prolongation in left parietal, bilateral frontal, and temporal white matter with meningeal enhancement. brain biopsy revealed the cerebral infiltration of CD3 , CD4 , CD8-, CD45RO , CD56-, and EBV-encoded rna 1 cells. CONCLUSIONS: The CNS involvement of EBV-associated T-LPD is a rare but serious complication in CAEBV without known underlying immunodeficiency.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/1600. Systemic candidiasis with candida vasculitis due to candida kruzei in a patient with acute myeloid leukaemia.candida kruzei-related systemic infections are increasing in frequency, particularly in patients receiving prophylaxis with antifungal triazoles. A Caucasian male with newly diagnosed acute myeloid leukaemia (AML M1) developed severe and persistent fever associated with a micropustular eruption scattered over the trunk and limbs during induction chemotherapy. Blood cultures grew candida kruzei, and biopsies of the skin lesions revealed a candida vasculitis. He responded to high doses of liposomal amphotericin b and was discharged well from hospital.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
3/1600. A case of acute phlegmonous gastritis successfully treated with antibiotics.Acute phlegmonous gastritis is a rare disorder in which bacterial infection occurs in the gastric wall. gastrectomy involving the affected area has been thought to be an effective form of treatment. The authors report a case of a 32-year-old woman who had severe upper abdominal pain without signs of peritoneal irritation. endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric antrum. Endoscopic ultrasonography showed thickening of the antral wall and a low-echoic mass in the gastric antrum, thought to represent a fluid collection. White pus was aspirated from the mass. Localized type of acute phlegmonous gastritis with a gastric abscess was diagnosed. culture of the pus showed streptococcus pneumoniae. Through early diagnosis without laparotomy, the patient's gastritis was successfully treated with antibiotics alone.- - - - - - - - - - ranking = 0.36497591313064keywords = infection, bacterial infection (Clic here for more details about this article) |
4/1600. prognosis of acute poststreptococcal glomerulonephritis in childhood: prospective study and review of the literature.Serial, clinical, clinicopathologic and histologic studies performed simultaneously following onset of PS-AGN in children for a period of up to 144 months revealed no evidence of progression to chronic glomerulonephritis. Although acute morphologic changes were more severe in renal tissue obtained from patients with AGN following streptococcal upper respiratory infection than following pyoderma, the acute manifestations in both groups subsided 6 to 12 weeks after onset. Cumulative morphologic healing occurred in 20% of patients at 24 months, in 43% at 48 months after onset of PS-AGN; 1 patient who was unhealed at 49 months was lost to follow-up. In 2 patients (6%), acute histologic exacerbations without clinical signs occurred within 24 months after onset. Subsequent healing was documented histologically. Addis counts remained abnormal in a high percentage of patients throughout the 12 years of observation and did not correlate with the histologic findings of renal biopsy tissue. The occasional demonstration of renal vascular disease and/or hypertension may merely reflect the early development of spontaneous essential hypertension although the possibility of a relationship to the previous attack of PS-AGN is intriguing. This question cannot be answered at this time. Renal biopsy studies are more dependable than Addis counts in assessing the course of PS-AGN. The significance of persistence of immunofluorescent and/or electron microscopic changes (subepithelial dense deposits) many years after onset in 58% of 12 patients studied, at a time when a majority of patients (84%) revealed healing by light microscopy, remains to be assessed.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
5/1600. Evolution of acute cytomegalovirus gastritis to chronic gastrointestinal dysmotility in a nonimmunocompromised adult.A 30-year-old nonimmunocompromised woman developed chronic gastrointestinal dysmotility as a consequence of acute cytomegalovirus infection. The acute nature of the infection was documented by high immunoglobulin m antibody titer to cytomegalovirus (CMV); the chronicity of the infection was shown by persistence of CMV in biopsy specimens of her gastrointestinal tract over a 21/2-year period. Gastrointestinal dysmotility was confirmed by delayed emptying on gastric nuclear scintigraphy, by retrograde propagation of migrating myoelectric complexes on small intestinal manometry, and by presence of tachygastria on cutaneous electrogastrography. The patient's nausea, vomiting, abdominal pain, and early satiety resolved after a short course of treatment with leuprolide acetate but returned after medication was discontinued. Her symptoms persisted despite clearance of CMV from the gastrointestinal tract after a course of treatment with ganciclovir. These observations show that acute CMV infection can cause gastrointestinal dysmotility in nonimmunocompromised individuals and that the disturbance in gastrointestinal motor function may persist for years after viral infection of the gastrointestinal tract has been eradicated.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
6/1600. Posttransplantation lymphoproliferative disorder mimicking a nonspecific lymphocytic pleural effusion in a bone marrow transplant recipient. A case report.BACKGROUND: Serous effusions are rare complications of bone marrow transplantation (BMT) and result mainly from infections or tumor relapse. CASE: We report a case of posttransplantation lympho-proliferative disorder (PTLD) revealed by cytodiagnostic examination of serous effusions in a BMT recipient. The effusion was initially considered reactive, but morphologic, immunocytologic and molecular studies subsequently revealed PTLD. CONCLUSION: This case demonstrates the importance of cytologic examination of effusions in BMT or organ recipients. Since most PTLDs are Epstein-Barr virus (EBV)-associated B-cell lymphoproliferative disorders and T cells predominate in reactive effusions, appropriate initial immunostaining, including CD3, CD79a and EBV latent membrane protein, should aid in their early detection.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
7/1600. 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 = 0.4keywords = infection (Clic here for more details about this article) |
8/1600. thalidomide in children undergoing bone marrow transplantation: series at a single institution and review of the literature.thalidomide has one of the most notorious drug histories because of its teratogenicity. Its widespread use in the 1960s led to a worldwide epidemic of phocomelia in inborns; this in turn led to its complete ban in most of the world. However, it has now been licensed for selected indications including graft-versus-host-disease (GVHD) after bone marrow transplantation, wasting associated with tuberculosis and human immunodeficiency virus infection, and leprosy. Little is known, however, about its use in children in these settings. Therefore, we report our experience and review the literature on thalidomide in children for GVHD after bone marrow transplantation. We studied 6 patients, 2 with chronic GVHD, 2 with acute GVHD, and 2 with acute GVHD progressing into chronic disease. One patient with chronic GVHD had a complete response, whereas the other had a partial response. Side effects consisted primarily of sedation and constipation, which are reported previously and well known side effects. None had neuropathy. One patient had rash, eosinophilia, and early pancreatitis that began shortly after initiation of thalidomide, persisted, and resolved only after discontinuation of thalidomide. eosinophilia and pancreatitis are both previously unreported side effects or associated findings of thalidomide treatment. review of the literature reveals three major studies of thalidomide in GVHD; of these two included children and adults together, and one in which age range of patients was not mentioned. In addition, four series of children receiving only thalidomide are reported. These series contained 1 to 14 patients each. Results show efficacy in at least 50% of children with chronic GVHD and little or no efficacy in children with exclusively acute GVHD. Side effects are similar to those reported in adults and consisted mostly of sedation and constipation, both of which subsided over time and resolved after discontinuing the drug. We speculate on the reasons for which thalidomide is more effective in chronic, compared with acute, GVHD in children, and make recommendations for future study.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
9/1600. 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 = 0.2keywords = infection (Clic here for more details about this article) |
10/1600. 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 = 1.2keywords = infection (Clic here for more details about this article) |
