The study aims to evaluate whether Dexamethasone reduces the risk of postoperative nausea and vomiting (PONV) in tonsillectomy in children. The results indicate that Dexamethasone reduced the risk of PONV but was associated with a greater risk of postoperative bleeding.

Abstract Background This study aimed to evaluate social evolution in Taiwan in recent decades using the changing pattern of care provided by grandparents for their grandchildren as an indicator. Methods Data from the second, fourth and sixth wave surveys of the Study of Health and Living Status of the Middle-Aged and Elderly in Taiwan were used for the analysis. This survey collected individual characteristics, including age, gender, education, ethnicity, dwelling place, living with partners, co-resident with children, employment status, self-reported health status and their provision of care for their grandchildren. Information about the attitudes toward National Health Insurance (NHI) was further collected in a questionnaire of 1999 following the implementation of NHI in 1995. By elders, we mean persons 60 or more years old. By grandchildren, we mean persons under 16 years of age. First, changes in individual characteristics were compared during these study periods (chi-square test). Then the logistic regression was performed to determine how significantly elders' grandchild-care behavior was associated with their individual characteristics. Results The percentage of elders providing grandchild care increased from 7.7% in 1993 to 13.6% in 1999, and then to 19.4% in 2007. By analysis, significant association was found between behavior in taking care of grandchildren and individuals of lower age, grandmothers, those living with partners or co-residing with children, those unemployed and those with better self-reported health status. And the effect of year was confirmed in the multivariable analysis. Conclusions This study pointed out the changing pattern of elders' behavior in taking care of their grandchildren as the main indicator and their related individual characteristics. We argue the need for improving social security policies in an ageing society. We suggest that the interaction between population policies and those of social welfare, including policies for health care and childcare, should be carefully evaluated.

Abstract Background With African health-care systems facing exploding demand for HIV care, reliable methods for assessing adherence and its influencing factors are needed to guide effective public-health measures. This study evaluated individual patient characteristics determining antiretroviral treatment (ART) adherence and the predictive values of different measures of adherence on virological treatment failure in a cohort of patients in a routine-care setting in Cameroon. Methods Longitudinal study over 6-months following ART introduction, using patients questionnaires and hospital and pharmacy records. Results At the end of the 6 months study period, 219 of 312 patients (70%) returned to the pharmacy to refill their medication, 17% (51) were lost to follow-up, 9% (28) were dead and 4% (14) were transferred to other care centres. Virological treatment failure at 6 months was experienced by 26 patients, representing 13% of patients with available viral load value. Pharmacy refill irregularity was the most powerful predictor (odds ratio 12.4; P < 0.001) of virological treatment failure, compared with CD4 cell count increase at 6 months (odds ratio 7.8; P = 0.002) or self-reported adherence at one month (odds ratio 1.1; P = 0.85). Low intensity of ART side-effects after one month was strongly associated with survival (odds ratio 0.11; P = 0.001). Patients starting ART with CD4 cell count 3 had a greater risk of dying during the follow-up period (odds ratio 2.69; P = 0.02). Compared with asymptomatic CDC stage A patients, CDC stage B (odds ratio 5.72) and CDC stage C patients (odds ratio 16.9) had higher risk of becoming lost to follow-up (P < 0.001). In the multivariate analyses, pharmacy non-adherence was less frequent in women (adjusted odds ratio 0.56; P = 0.05) but more frequent in patients with high monthly income (odds ratio 3.24; P = 0.04). Conclusion Pharmacy-refill adherence might be considered as an alternative to CD4 count monitoring for identification of patients at risk of virological failure, especially in resources-scarce countries. The study confirmed the difficulty in demonstrating clear associations of individual patient factors and treatment outcomes. The substantial loss to follow-up and deaths occurring within 6 months after initiating ART emphasise the need to understand the best timing of ART initiation and further elucidate and educate on the underlying reasons for delaying initiation of ART in resource-limited countries

Background and Objective: The aim of this systematic review was to indirectly compare the efficacy of any intervention, administered perioperatively, on acute and persistent pain after breast surgery.Databases and Data Treatment: We searched for randomized trials comparing analgesic interventions with placebo or no treatment in patients undergoing breast surgery under general anaesthesia. Primary outcome was intensity of acute pain (up to 6 hr postoperatively). Secondary outcomes were cumulative 24-hr morphine consumption, incidence of postoperative nausea and vomiting (PONV), and chronic pain. We used an original three-step approach. First, meta-analyses were performed when data from at least three trials could be combined; secondly, trial sequential analyses were used to separate conclusive from unclear evidence. And thirdly, the quality of evidence was rated with GRADE.Results: Seventy-three trials (5,512 patients) tested loco-regional blocks (paravertebral, pectoralis), local anaesthetic infiltrations, oral gabapentinoids or intravenous administration of glucocorticoids, lidocaine, N-methyl-D-aspartate antagonists or alpha2 agonists. With paravertebral blocks, pectoralis blocks and glucocorticoids, there was conclusive evidence of a clinically relevant reduction in acute pain (visual analogue scale > 1.0 cm). With pectoralis blocks, and gabapentinoids, there was conclusive evidence of a reduction in the cumulative 24-hr morphine consumption (> 30%). With paravertebral blocks and glucocorticoids, there was conclusive evidence of a relative reduction in the incidence of PONV of 70%. For chronic pain, insufficient data were available.Conclusions: Mainly with loco-regional blocks, there is conclusive evidence of a reduction in acute pain intensity, morphine consumption and PONV incidence after breast surgery. For rational decision making, data on chronic pain are needed.Significance: This quantitative systematic review compares eight interventions, published across 73 trials, to prevent pain after breast surgery, and grades their degree of efficacy. The most efficient interventions are paravertebral blocks, pectoralis blocks and glucocorticoids, with moderate to low evidence for the blocks. Intravenous lidocaine and alpha2 agonists are efficacious to a lesser extent, but with a higher level of evidence. Data for chronic pain are lacking. [ABSTRACT FROM AUTHOR]
