A ten-hour old newborn found in the street where a dog was savaging him, was brought to Black Lion Hospital in 1998. The history, physical findings and radiological features suggested widespread subcutaneous fat necrosis, which later became calcified. Although this is a rare condition, medical workers need to be aware of the possibility of this self-limiting disease, which may occur in abandoned and hypothermic neonates. 相似文献

BACKGROUND: We have previously suggested that helminthic infections make the host more susceptible to HIV infection and enhance its progression due to the chronic immune activation they cause. OBJECTIVE: To study the effect of antihelminthic treatment on HIV plasma viral load (VL) in HIV- and helminth-infected individuals living in Ethiopia. METHODS: Fifty-six clinically asymptomatic HIV-1-infected individuals, 31 (55%) of whom were also infected with helminths, were studied. All participants received antihelminthic treatment at baseline and at 3 and 6 months. Worm egg excretion, HIV plasma VL, and T-cell subsets were determined at baseline and 6 months after treatment. RESULTS: The mean age, number of CD4 T cells, and gender distribution were similar in the helminth-infected and -noninfected groups. At baseline, HIV plasma VL was strongly correlated to the number of eggs excreted (p <.001) and was higher in individuals infected with more than one helminth (5.28 +/- 0.35 versus 4.30 +/- 1.13 log RNA copies/mL, respectively; p =.16). After treatment of helminths, the 6-month change in HIV plasma VL was significantly different between the successfully treated group and the persistently helminth-positive group (p =.04) CONCLUSIONS: Helminth "load" is correlated to HIV plasma VL, and successful deworming is associated with a significant decrease in HIV plasma VL. The results of the current study, if confirmed in a larger study, may have important implications for slowing disease progression and reducing risks of transmission. 相似文献

The HIV/AIDS pandemic is spreading at an alarmingly high rate in Africa. Leishmaniasis is also highly prevalent in the continent. Despite the emergence of Leishmania/HIV co-infection in Africa, the numbers reported are disproportionately low. Moreover, the number of cases of co-infection is expected to rise in Africa owing to the simultaneous spread of the two infectious diseases and their increasingly overlapping geographical distribution. 相似文献

SETTING: Tuberculosis programme in six camps (Benaco, Musuhura, Lumasi, Lukole, Keza and Kitali) for Rwandan and Burundian refugees in Ngara district, Tanzania, where treatment was directly observed throughout. OBJECTIVES: To evaluate the treatment outcome of sputum smear-positive tuberculosis cases recruited in refugee camps in Ngara, and to determine the cumulative frequency of conversion of sputum smears by direct microscopy. DESIGN: Retrospective review of tuberculosis registers from January 1995 to December 1999. RESULTS: Of 546 patients with smear-positive tuberculosis who were notified in the programme, 363 (66.5%) had completed treatment and were bacteriologically cured after 7 months, 10.9% had died, 7.1% had defaulted and 14.5% had transferred out. Sputum conversion after the 2-month intensive phase was 88%, and increased to 99% after 7 months of chemotherapy. CONCLUSION: The involvement of the Tanzania NTLP in collaboration with health NGOs has led to a satisfactory outcome. These data suggest that it is possible for tuberculosis control programmes to perform successfully in refugee settings. 相似文献

Cutaneous infection with Mycobacterium chelonae is an uncommon disease, although this atypical mycobacterium is an acid-fast bacillus ubiquitous in the environment. It is often misdiagnosed and treated as a fungal or common bacterial infection. We report a case of disseminated atypical mycobacterial skin infection of a 72-year-old woman who was treated with different topical and systemic antimycotic and antibiotic drugs over a period of 5 months without remarkable improvement. Eventually, repeated tissue cultures on special medium and performance of PCR led to the diagnosis of M. chelonae infection. The patient was treated successfully with oral clarithromycin within 8 weeks. In case of abscessing cutaneous infection, M. chelonae should be considered in the differential diagnosis of prolonged disease when common antibiotics are not effective after 2-4 weeks of treatment. 相似文献
