1/1583. Pseudogaucher cells in cutaneous mycobacterium avium intracellulare infection: report of a case.We report on a patient infected with human immunodeficiency virus, and with cutaneous mycobacterium avium intracellulare, in whom many cells with abundant reticulated cytoplasm resembling the characteristic cells of Gauchers disease ("pseudogaucher cells") were noted within the dermal infiltrate on biopsy. Although pseudogaucher cells have been reported in association with M. avium intracellulare infection in extracutaneous sites, this is, to our knowledge, the first report of cutaneous pseudogaucher cells in the skin.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
2/1583. Laryngeal pathology in the acquired immunodeficiency syndrome: diagnostic and therapeutic dilemmas.The acquired immunodeficiency syndrome has produced a growing population of patients who, because of their associated immune system compromise, are prone to opportunistic infections and neoplastic diseases. The larynx, with its relatively inaccessible yet critical anatomic location, is a site in which these processes can produce clinical dilemmas, with respect to diagnosis as well as to therapy. By presenting 4 cases involving unusual laryngeal problems in patients infected with the human immunodeficiency virus (HIV), we emphasize these inherent diagnostic and therapeutic problems. Otolaryngologists must be familiar with the many diagnostic possibilities and therapeutic alternatives when HIV-infected patients present with laryngeal complaints.- - - - - - - - - - ranking = 45.850384118976keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
3/1583. arthritis due to mycobacterium fortuitum.mycobacterium fortuitum is classified as a rapidly growing mycobacterium (RGM) according to the Runyon classification. RGM are increasingly being recognized as human pathogens. Joint infection due to M. fortuitum is a rare, but serious disease. This report describes a patient with acquired immunodeficiency syndrome (AIDS) and septic arthritis of the knee due to M. fortuitum in a previously normal joint with no history of surgery or intra-articular injections.- - - - - - - - - - ranking = 8.9700768237953keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
4/1583. Progressive outer retinal necrosis syndrome as an early manifestation of human immunodeficiency virus infection.Progressive outer retinal necrosis syndrome is a recently recognized variant of necrotizing herpetic retinopathy, developing in patients with acquired immune deficiency syndrome (AIDS) or other conditions causing immune compromise. We report a case in which the diagnosis of retinal necrosis syndrome was made before the diagnosis of AIDS was confirmed. A 41-year-old man presented with a 1-month history of blurred vision in his left eye. Ophthalmologic examination revealed extensive retinal necrosis with total retinal detachment in his left eye and multifocal deep retinal lesions scattered in the posterior fundus as well as in the peripheral retina in his right eye. The serologic test for human immunodeficiency virus (HIV) was positive. Despite intravenous acyclovir treatment for 1 week, the lesions in the right eye showed rapid progression. High doses of intravitreal ganciclovir were then given in addition to intravenous acyclovir. After combined treatment for 1 month, the lesions became quiescent and the visual acuity improved to 20/30. Although the patient soon developed full-blown AIDS, the vision in his right eye remained undisturbed. physicians should suspect progressive outer retinal necrosis syndrome in any patient with rapidly progressive necrotizing retinopathy and test the patient for HIV infection. Aggressive combined antiviral agent therapy should be considered to save vision.- - - - - - - - - - ranking = 5keywords = immunodeficiency (Clic here for more details about this article) |
5/1583. An HIV autopsy--characterization of zidovudine-resistant subtype E hiv-1 from autopsy tissue suggests the route of infection and an alternative protocol of therapy.This CPC concerns a 47-year-old male patient with acquired immunodeficiency syndrome (AIDS). The patient became symptomatic when he developed pneumocystis carinii pneumonia, but recovered sufficiently to be treated as an outpatient. Two years after falling ill, he developed septic shock and died within a short time. During this period, he failed to respond to HIV drugs, and there was no improvement in his immunodeficient status. The HIV retrieved from the patient's organs at autopsy was found to be type E and to have acquired resistance to zidovudine. It was also possible to determine the route of infection. HIV treatment guidelines are continuously being revised on the basis of HIV research and the development of new treatment plans, and at the present time, when no definitive method of treatment has yet been established, it is essential for the clinician to keep abreast of the latest information. Since HIV patients are compromised hosts, it is important to diagnose and treat other infectious complications, not only complications unique to AIDS, and we have briefly described the latest HIV therapy.- - - - - - - - - - ranking = 8.9700768237953keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |

7/1583. typhoid fever and HIV infection: a rare disease association in industrialized countries.typhoid fever is still a global health problem, mainly in tropical and subtropical areas of the world and in developing countries, where relatively elevated morbidity and mortality rates still are present, mostly because of persisting poor hygienic conditions. In the majority of Mediterranean regions, including italy, the disease is constantly present, though with a low prevalence rate, as a result of an endemic persistence of salmonella typhi infection.1-4 On the other hand, in industrialized countries, most cases of S. typhi infection are related to foreign travel or prior residence in endemic countries.4-6 In the united states, 2445 cases of typhoid fever have been reported in the decade 1985 to 1994, and the annual number of cases remained relatively stable over time: over 70% of episodes were acquired in endemic countries (mostly mexico and india).6 The persisting morbidity of S. typhi also may be supported by the increasing resistance rate of this pathogen against a number of commonly used antimicrobial compounds. For instance, 6% of 331 evaluable S. typhi strains were resistant to ampicillin, chloramphenicol, and cotrimoxazole, and 22% of isolates were resistant to at least one of these three agents in a recent survey performed in the united states.6 The spread of antibiotic resistance among S. typhi isolates is emerging in many countries, and multidrug-resistant strains have been isolated, as well as isolates with poor susceptibility to fluoroquinolones,3-5,7-9 so that in vitro susceptibility should be determined for all cultured strains, and antimicrobial treatment should be adjusted accordingly. Nevertheless, fluoroquinolones (e.g., ciprofloxacin and pefloxacin) or third-generation cephalosporins, still represent the best choice for empirical treatment,2,4,6-8,10 and mortality remains rare in Western countries (less than 1% of episodes), although it is expected to be greater in developing areas of the world. The aim of this report is to describe two cases of typhoid fever that occurred in patients with human immunodeficiency virus (HIV) infection, a rarely reported disease association in industrialized countries.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
8/1583. Endoscopic features of intestinal smooth muscle tumor in a child with AIDS.Intestinal leiomyosarcomas are exceedingly rare in immunologically intact children, except during infancy. While leiomyosarcomas account for less than 2% of all soft tissue tumors in childhood, they are the second most frequent malignancy in children with the acquired immunodeficiency syndrome (AIDS). In this cohort they are often located in unusual sites for primary soft tissue tumors. This report describes a young girl with advanced AIDS, referred for evaluation of abdominal pain, hematochezia, and wasting syndrome. colonoscopy revealed two 1- to 2-cm submucosal nodules with central umbilication. Repeat colonoscopy 18 months later revealed no changes in these lesions. biopsy revealed a submucosal spindle-cell lesion, with necrosis and cellular atypia. Initially it was characterized as a partially excised low-grade leiomyosarcoma. However, the final consensus diagnosis was smooth muscle tumor of uncertain malignant potential. Because of her advanced AIDS, there was no attempt at surgical resection or chemotherapy. Thirty-six months after initial referral, she remains alive without radiographic or clinical evidence of local extension or metastases. Additional data are required to determine the long-term outcome of these indolent submucosal tumors in the digestive tracts of children with AIDS.- - - - - - - - - - ranking = 8.9700768237953keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
9/1583. Angiotropic (intravascular) large cell lymphoma of T-cell phenotype presenting as acute appendicitis in a patient with acquired immunodeficiency syndrome.We describe a patient with acquired immunodeficiency syndrome who presented with acute appendicitis but was found to have angiotropic large cell lymphoma (ALCL) by pathologic examination of the appendectomy specimen, without acute inflammation. Very rare cases of angiotropic large cell lymphoma have been reported in patients with human immunodeficiency virus infection, and most cases of this rare lymphoma are of B-cell origin, but in this instance immunohistochemical analysis showed a T-cell phenotype.- - - - - - - - - - ranking = 45.850384118976keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
10/1583. paclitaxel in the treatment of human immunodeficiency virus 1-associated Kaposi's sarcoma--drug-drug interactions with protease inhibitors and a nonnucleoside reverse transcriptase inhibitor: a case report study.PURPOSE: To describe the pharmacokinetics of paclitaxel and to investigate the interaction potential with protease inhibitors (indinavir, ritonavir, saquinavir) and the nonnucleoside reverse transcriptase inhibitor nevirapine, for which strong theoretical indications for clinically relevant drug interactions exist. methods: The 24-h plasma pharmacokinetics of paclitaxel (Taxol, given at 100 mg/m2 by 3-h intravenous infusion) and concomitantly infused antiretroviral drugs were determined in a human immunodeficiency virus 1 (hiv-1)-infected male patient with refractory Kaposi's sarcoma (KS) during high-activity antiretroviral therapy and after discontinuation of this regimen. The plasma pharmacokinetics of paclitaxel, indinavir, ritonavir, saquinavir, and nevirapine were closely monitored. Since all these drugs are extensively metabolized via the cytochrome P450 enzyme system and are substrates for the multidrug transporter p-glycoprotein, investigation of drug-drug interactions was considered important. RESULTS: In this case report study the pharmacokinetics of paclitaxel given concomitantly with various antiretroviral drugs were comparable with those of historical controls who had been treated with single-agent paclitaxel. The pharmacokinetics of indinavir, ritonavir, saquinavir, and nevirapine were also not statistically significantly different from those recorded for historical controls. paclitaxel was well tolerated and resulted in a significant clinical response in this patient. CONCLUSION: Dose adjustments of paclitaxel, indinavir, ritonavir, saquinavir, or nevirapine are apparently not needed if hiv-1-associated KS is treated with paclitaxel at a dose of 100 mg/m2 as shown in the present case. It is stressed, however, that controlled studies are necessary to substantiate these preliminary case report findings.- - - - - - - - - - ranking = 5keywords = immunodeficiency (Clic here for more details about this article) |
