Thalidomide has a beneficial effect on type II Lepra reaction especially chronic and recurrent reaction. It helps to minimise steroid dependency. Thalidomide was given to 94 cases of type II lepra reaction, who had not responded to steroids or had repeated reactions. This clinical data was analysed regarding clinical improvement, relapse of reaction, side effects of the drug, etc. The analysis showed that all the patients improved remarkably and steroids could be withdrawn. If the competence of staff using this drug is enhanced, morbidity due to leprosy can considerably be reduced. 相似文献

Transmission of leprosy which is related directly to the total quantum of infection in the community as a whole is decided by the existence of patients suffering from progressive and infectious forms of leprosy and their movement from place to place. This information is of great importance in cities like Bombay to identify the priority areas as targets towards which control efforts should be directed. In this presentation an attempt has been made to compare the leprosy survey figures from three different situations in the city. Selection is arbitrary, not made on statistical basis. The data of particular importance is from a leprosy colony located in North Bombay representing a hyperendemic situation and a normal slum adjacent to this colony, movement of population between these two colonies being free. Age specific prevalence rates of leprosy after examining more than 80% of population from these colonies are compared with data derived from normal slums situated elsewhere in the city. The figures reveal varying prevalence rates marked by an increasing trend in the prevalence figures, leprosy colony representing the largest pool of infection. These figures indicate that wider statistically planned investigations on similar lines in urban areas may provide epidemiological data useful for planning control measures on a more rational basis. 相似文献

Cladophialophora bantiana is a dematiaceous mold with a predilection for causing central nervous system infection, particularly in normal hosts. A case involving a 79-year-old immunocompetent woman who presented with left-sided weakness and a ring-enhancing brain lesion is reported. She underwent surgical excision, which revealed a brain abscess due to C bantiana. The patient was treated with liposomal amphotericin B for several weeks, then switched to voriconazole and flucytosine, but eventually succumbed to the infection. Therapy is not standardized for this rare mycosis, and mortality remains high, even in immunocompetent patients. Additional studies to understand the pathogenesis of this infection and to improve outcomes are needed. 相似文献

In preclinical investigations performed in mice, 2-amino-9-beta-D-ribofuranosyl purine-6-sulfinamide (sulfinosine), a novel derivative of 6-thioguanosine (6TGR), was active against six solid tumors and four strains of experimental leukemia. Sulfinosine penetrated the central nervous system more readily than did 6TGR and, when given repeatedly, was much more effective in the treatment of L1210 leukemia, being curative for some mice. Other findings of major interest to us were the different dosing characteristics of sulfinosine and 6TGR, the divergent efficiencies of the two drugs in generating cellular resistance, and the activity of sulfinosine against experimental leukemias refractory to 6TGR and other experimental or clinically used chemotherapeutic agents. The chemotherapeutic characterization of sulfinosine that evolved from these studies suggests that this agent may have unique properties that deserve clinical consideration. Both the dosing characteristics of the drug and its pronounced activity against thiopurine-resistant experimental leukemia favor the possibility that sulfinosine could be used to advantage in the treatment of human leukemia unresponsive to 6-mercaptopurine or 6-thioguanine. 相似文献

In the absence of definite evidence on utility of intensive therapy with rifampicin in multibacillary leprosy cases, a laboratory based investigation was undertaken basically to compare the efficacy of WHO and IAL regimens. In each group 4 untreated BL-LL patients were included and their skin biopsies were subjected for viability test both in vitro and in vivo systems. A consistant fall in BI with good clinical improvement was observed in both the groups. However good viability was maintained till about third pulse dose in WHO group whereas under IAL group rapid fall in viability was observed after intensive phase. Viable bacilli were seen even after 12,15,18 and 24 doses in both groups. These findings question the need for additional 21 doses of rifampicin in IAL schedule. However such studies are to be repeated on larger samples. 相似文献

Topical application of 9-beta-d-arabinofuranosylhypoxanthine 5'-monophosphate (ara-HxMP) significantly inhibited the development of keratitis induced by types 1 and 2 herpes simplex virus and vaccinia virus in the eyes of rabbits. Parameters for evaluation of efficacy were infectivity (corneal opacity, lesion size, and type), Draize (erythema, conjunctival swelling, and discharge), and reduction in titer of recoverable virus from the eye. When the relative efficacy of the related compounds 9-beta-d-arabinofuranosyladenine (ara-A), ara-A 5'-monophosphate (ara-AMP), and ara-Hx was determined against type 1 herpes simplex virus in a parallel experiment, the more water-soluble compounds (ara-HxMP, ara-AMP) were the most effective. The relative efficacy of ara-A was also determined against type 2 herpes and vaccinia virus-induced keratitis. Mortality in rabbits due to central nervous system involvement caused by types 1 and 2 herpes simplex virus was inhibited. Ara-HxMP was not discernibly toxic to the eye at concentrations of at least 20%; efficacy was still discernible with a 0.1% solution. 相似文献

Zygomycosis, an infection that is associated with significant morbidity and mortality, is becoming common in immunocompromised patients. Posaconazole is a new extended-spectrum azole antifungal that has demonstrated in vitro and in vivo activity against zygomycetes. This report provides the results from the first 24 patients with active zygomycosis who were enrolled in two open-label, nonrandomized, multicentered compassionate trials that evaluated oral posaconazole as salvage therapy for invasive fungal infections. Posaconazole was usually given as an oral suspension of 200 mg four times a day or 400 mg twice a day. Eleven (46%) of the infections were rhinocerebral. Duration of posaconazole therapy ranged from 8 to 1,004 days (mean, 292 days; median, 182 days). Rates of successful treatment (complete cure and partial response) were 79% in 19 subjects with zygomycosis refractory to standard therapy and 80% in 5 subjects with intolerance to standard therapy. Overall, 19 of 24 subjects (79%) survived infection. Survival was also associated with surgical resection of affected tissue and stabilization or improvement of the subjects' underlying illnesses. Failures either had worsening of underlying illnesses or requested all therapy withdrawn; none of the failures received more than 31 days of posaconazole. Posaconazole oral solution was well tolerated and was discontinued in only one subject due to a drug rash. Posaconazole appears promising as an oral therapy for zygomycosis in patients who receive required surgery and control their underlying illness. 相似文献
