Objectives
Voluntary counselling and testing (VCT) for HIV infection is an important tool for prevention of HIV infection and AIDS in high‐risk groups. Our goal was to describe the acceptability and consequences of VCT among a stigmatized and vulnerable group, female sex workers (FSWs), in Conakry, Guinea.Methods
Acceptance of the test and return for test results at baseline and consequences of testing 1 year later were described. The perceived risk of HIV infection and perceived benefits and barriers to testing were examined using quantitative and qualitative methods.Results
All 421 FSW participants agreed to undergo VCT and most participants (92%) returned for their results. The main reason cited for VCT acceptance was the wish to know their HIV status. However, some managers of FSW worksites urged FSWs to be tested, curtailing FSWs' free decision‐making. One year later, status disclosure was common (90% of the 198 individuals who knew their results among those who participated in the follow‐up part of the study). Positive consequences of testing were far more frequently reported than negative consequences (98% vs. 2%, respectively). Negative life events included banishment from the worksite (one case) and verbal abuse (two cases).Conclusion
Acceptability of VCT appears high in the FSW population in Conakry as a consequence of both perceptions of high individual risk and social pressures. 相似文献32.

Objective
To evaluate the efficacy of single oral mega-dose of Vitamin D3 for treatment and prevention of pneumonia in underfive children.Design
Randomized, double blind, placebo-controlled trial.Setting
Tertiary-care hospital.Participants
324 children (of 980 assessed) between 6 mo-5 y age (median (IQR): 12 (7,19.8) mo) with WHO-defined severe pneumonia. Of these, 126 (39%) were vitamin D deficient (serum 25(OH)D <12 ng/mL).Intervention
100,000 IU of oral cholecalciferol (n= 162) or placebo (n= 162) in single dose, administered at enrolment.Outcome variables
Primary: Time to resolution of severe pneumonia and proportion of children having recurrence of pneumonia in next 6 months; Secondary: Change in serum levels of 25(OH)D; immunoglobulins IgA, IgG, IgM, and cathelicidin 2 weeks following supplementation; and time taken for overall resolution of illness.Results
Median (95% CI) time for resolution of severe pneumonia was 30 (29, 31) h in the vitamin D group as compared to 31 (29,33) h in the placebo group [adjusted hazard ratio (95% CI): 1·39 (1·11, 1·76); P=0·005]. The risk of recurrence of pneumonia in next 6 months was comparable in the two groups [placebo: 36/158 (22·8%); vitamin D: 39/156 (25%); RR (95% CI): 1·13 (0·67,1·90); P=0·69]. Proportion of vitamin D deficient children declined from 38% to 4% in the supplementation group, and from 41% to 33% in the placebo group, two weeks after supplementation. There was no significant effect of vitamin D supplementation on serum levels of cathelicidin, IgA and IgG. The time taken for complete recovery from pneumonia, duration of hospitalization, and fever clearance time were comparable for the two groups. No adverse event was noted related to the intervention.Conclusion
There is no robust evidence of a definite biological benefit, either for therapy or prevention, to suggest a routine megadose supplement of vitamin D3 for under-five children with severe pneumonia.35.
This study measured the levels of patient satisfaction in those who received treatment with implant-retained overdentures, and compared their status before and after therapy. Satisfaction questionnaires were mailed to patients who had previously worn a removable prosthesis. Questions addressed eating, aesthetics and comfort before and after the treatment. Eighty-six (79.8%) subjects had problems regarding looseness of their denture prior to treatment. Patients were generally satisfied with their implant-retained overdentures in terms of function, comfort, appearance and speech. The results suggest that unstable, problematic complete dentures can be managed by providing patients with implant-retained overdentures. Clinical Relevance: From the patients' perspective, implant-supported overdentures offer overall satisfaction and improvement. 相似文献

Bony anatomical anomalies can complicate the construction and successful wearing of removable prostheses. Osteopetrosis is a group of diseases that affect the growth and continuous remodelling of bone which in turn can result in gross irregular alveolar bone morphology. This paper describes the management of a patient with this problem and emphasises the challenges in constructing a successful complete maxillary removable prosthesis. The utilisation of a flexible base plate material as an alternative to traditional materials will be highlighted. Irregular bony morphology is a recognised potential obstacle to the successful construction of removable prostheses. In most cases the problem can be overcome but in extreme and less common circumstances, management of these features can be more problematic. This paper describes a technique used to manage extreme alveolar irregularity which may perhaps be applied to those problems more commonly encountered in every day clinical practice but are less extreme then those described in this paper. 相似文献

BACKGROUND: Efforts to intensify global tuberculosis (TB) control are limited by difficulties in coordinating with private doctors. More than half of Indian TB patients may initially consult a private provider, but many are neither diagnosed accurately nor treated effectively. We established and evaluated a public-private partnership based on surveillance of TB detected in private laboratories and use of standardised directly observed treatment regimens. METHODS: In one district, the governmental TB control programme offered training in microscopy to all large private sector laboratories, and educated private physicians on the importance of microscopy for TB diagnosis. We reviewed records from participating private laboratories and all publicly diagnosed patients. RESULTS: Of 2328 pulmonary TB patients registered from July 2001 to December 2002, 404 (17%) were detected in the private sector. The annual new AFB-positive case notification rate increased by 21%, from 27.8/100,000 in 2000 to 33.5/100,000 in 2002. Surveillance at private laboratories found an additional 260 nonregistered AFB-positive patients. CONCLUSIONS: This public-private partnership substantially increased TB case detection and established a sustainable framework for private sector involvement in TB control. In the setting of a strong public sector programme, the combination of active surveillance of private laboratories along with physician sensitisation is a promising approach to improve TB case detection. 相似文献

BackgroundThe aim of this study was to explore the role of three-dimensional (3D) endoscopy in surgical management of metastatic disease of the dorsal and lumbar spine.MethodsThis is a prospective study on 33 patients (15 men and 18 women, mean age of 61.6 ± 8.9 years) with biopsy-proven metastatic disease of the spine managed by sequential/staged posterior decompression-stabilization, followed by 3D endoscopy-assisted anterior corpectomy and stabilization with a mesh cage. All patients had significant extradural compression or spinal instability or both. Sixteen patients had neurological deficits. Visual analog scale (VAS), Frenkel grade (neurological deficits), Karnofsky performance status scale, and the 36-item short-form health survey (SF-36) were used for assessment preoperatively and at 3, 6, and 12 months from surgery.ResultsAt a mean follow-up of 1.7 ± 0.7 years from surgery, 18 patients were alive. VAS showed significant improvement at the latest follow-up compared to preoperative levels (4.39 vs. 6.61, p = 0.001). Karnofsky status did not show any significant improvement. Frenkel grade improved in 5 patients, deteriorated in 4 patients, and remained unchanged in 24 patients. Regarding SF-36 parameters, general health showed deterioration, but role functioning—physical, role functioning—emotional, social functioning, and body pain showed statistically significant improvement. There was no change in physical health, viability, and mental health. Subjectively the surgeons felt better depth perception and smoother surgical experience with the 3D optics technology. The only complication was delayed wound healing in three patients who had a previous history of radiotherapy to the surgical site.Conclusions3D endoscopy is a valuable tool in the management of metastatic spinal disease requiring excision and reconstruction using the combined posterior and anterior approaches. These early results warrant confirmation with more data and longer follow-ups. 相似文献

Rationale: There is a paucity of population-based data on COPD prevalence and its determinants in Bangladesh.Objective: To measure COPD prevalence and socioeconomic and lifestyle determinants among ≥40 years Bangladeshi adults.Methods: In a cross-sectional study, we measured lung function of 3744 randomly selected adults ≥40 years from rural and urban areas in Bangladesh, using a handheld spirometer. COPD was defined according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria as post-bronchodilator ratio of Forced Expiratory Volume in 1st second (FEV1) to Forced Vital Capacity (FVC) <?0.7. In addition, COPD was also assessed by the lower limit of normal (LLN) threshold defined as lower fifth percentile for the predicted FEV1/FVC.Results: The prevalence of COPD was 13.5% by GOLD criteria and 10.3% by LLN criteria. Prevalence of COPD was higher among rural than urban residents and in males than females. More than half of the COPD cases were stage II COPD by both criteria. Milder cases (Stages I and II) were over estimated by the GOLD fixed criteria, but more severe cases (Stages III and IV) were similarly classified. In multiple logistic regression analysis, older age, male sex, illiteracy, underweight, history of smoking (both current and former), history of asthma and solid fuel use were significant predictors of COPD.Conclusion: COPD is a highly prevalent and grossly underdiagnosed public health problem in Bangladeshi adults aged 40 years or older. Illiteracy, smoking and biomass fuel burning are modifiable determinants of COPD. 相似文献
