Tonsillotomy: An alternative surgical option to total tonsillectomy in children with obstructive sleep apnoea.

BACKGROUND: Total tonsillectomy remains one of the most common ear, nose and throat (ENT) procedures performed in children. General practitioners (GPs) are commonly involved in the referral of children with obstructive sleep apnoea (OSA). Intracapsular tonsilltomy (partial tonsillectomy) is fast becoming a popular surgical option to total tonsillectomy in children with OSA. OBJECTIVE: The objective of this article is to provide information about partial tonsillectomy and its potential benefits over total tonsillectomy in the treatment of children with OSA for referring GPs. DISCUSSION: Current evidence suggests that partial tonsillectomy is a safe and effective treatment for children with OSA. Partial tonsillectomy has been shown to be associated with a lower incidence of postoperative haemorrhage, faster recovery time and higher parent satisfaction than total tonsillectomy. Furthermore, it has been found to have comparable results to total tonsillectomy in the improvement of OSA symptoms in children.

Injectable vaccines for preventing pneumococcal infection in patients with chronic obstructive pulmonary disease.

BACKGROUND: As chronic obstructive pulmonary disease (COPD) progresses, exacerbations can occur with increasing frequency. One goal of therapy is to prevent these exacerbations, thereby reducing morbidity and associated healthcare costs. Pneumococcal vaccinations are one strategy for reducing the risk of infective exacerbations. OBJECTIVES: To determine the safety and efficacy of pneumococcal vaccination in COPD. The primary outcomes assessed were episodes of pneumonia and acute exacerbations. Secondary outcomes of interest included hospital admissions, adverse events related to treatment, disability, change in lung function, mortality, and cost effectiveness. SEARCH STRATEGY: We searched the Cochrane Airways Group COPD trials register and the databases CENTRAL, MEDLINE and EMBASE using pre-specified terms. The latest searches were performed in March 2010. SELECTION CRITERIA: Randomised controlled trials assessing the effects of injectable pneumococcal vaccine in people with COPD were included. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and three review authors independently assessed trial quality. MAIN RESULTS: Seven studies were identified that met the inclusion criteria for this review and were included in the 2010 review update. Two older trials used a 14-valent vaccine and five more recent trials used a 23-valent injectable vaccine.In six studies involving 1372 people, the reduction in likelihood of developing pneumonia with pneumococcal vaccination compared to control did not achieve statistical significance, the odds ratio (OR) was 0.72 (95% confidence interval (CI) 0.51 to 1.01), with moderate heterogeneity present between studies. The reduction in likelihood of acute exacerbations of COPD from two studies involving 216 people was not statistically significant (Peto OR 0.58; 95% CI 0.30 to 1.13).Of the secondary outcomes for which data were available there was no statistically significant effect for reduction in hospital admissions (two studies) or emergency department visits (one study). There was no significant reduction in pooled results from three studies involving 888 people for odds of all-cause mortality for periods up to 48 months post-vaccination (OR 0.94; 95% CI 0.67 to 1.33), or for death from cardiorespiratory causes (OR 1.07; 95% CI 0.69 to 1.66). AUTHORS' CONCLUSIONS: The limited evidence from randomised controlled trials (RCTs) included in this review suggests that, while it is possible that injectable polyvalent pneumococcal vaccines may provide some protection against morbidity in persons with COPD, no significant effect on any of the outcomes was shown. Further large RCTs in this population would be needed to confirm effectiveness of the vaccine suggested by results from longitudinal studies.

Metastatic prostate cancer incidence in Australia after amendment to prostate-specific antigen screening guidelines.

BACKGROUND: To compare the incidence of newly diagnosed metastatic prostate cancer at an Australian facility pre- and post-publication of the United States Preventive Services Task Force (USPSTF) guidelines and subsequent amendment of the Royal Australian College of General Practitioners Preventive Activities in General Practice guidelines. METHODS: A retrospective analysis was undertaken by patients with newly diagnosed prostate cancer following transrectal ultrasound-guided biopsy between 2009 and 2014. Patients were divided into two even groups based on whether they had undergone their transrectal ultrasound biopsy pre- (2009-2011) or post- (2013-2014) publication of USPSTF guidelines. Metastatic disease was determined by computed tomography chest, abdomen, pelvis as well as nuclear medicine bone scan. A comparison in the incidence of newly diagnosed metastatic prostate cancer was made. RESULTS: A total of 130 patients were allocated into each group. In the pre-USPSTF group, 23 out of 130 patients had newly diagnosed metastatic prostatic cancer (17.7%). In the post-USPSTF group, 41 out of 130 (31.5%) had newly diagnosed metastatic prostate cancer (P < 0.05). The mean and median prostate-specific antigen was 15.9 and 9.4 (pre-guideline group) and 33.0 and 9.8 (post-guideline group), respectively (P = 0.02). The post-guidelines group had a higher incidence of low-grade disease (Gleason <7), a decreased incidence of intermediate grade disease (Gleason 7) and a relatively unchanged incidence in high-risk disease (Gleason >7). CONCLUSION: The incidence of newly diagnosed metastatic prostate cancer nearly doubled in patients referred to our Urology Department post-release of the USPSTF guidelines.

Mastery learning: how is it helpful? An analytical review.

The desire to be good at one's work grows out of the aspiration, competition, and a yearning to be the best. Surgeons, in their aim to provide the best care possible to their patients, adopt this behavior to achieve high levels of expert performance through mastery learning, and the surgical training attempts to prepare them optimally to lead a virtuous and productive life. The proponents of the framework reject evidence that suggests that other variables are also necessary to achieve high levels of expert performance. Here, we review various models and designs to achieve mastery along with their pros and cons to help us understand how mastery learning is helpful in surgical practice.
