A Management of Early CRPS I Caused by Ankle Sprain: A Case Report

Abstract:   We present a case of a 13-year-old boy who developed signs and symptoms of neuropathic pain/early Complex Regional Pain Syndrome (CRPS) Type I, formerly known as Reflex Sympathetic Dystrophy (RSD), after spraining his ankle while wrestling. Aggressive pain control, using medications and sympatholytic blocks, with physical therapy and rehabilitation, led to the resolution of his painful condition. This prevented the disease from possibly progressing to a full-blown case of CRPS I (RSD) that is very challenging to treat.     

Is same-day discharge associated with increased 30-day postoperative complications and readmissions in patients undergoing laparoscopic adrenalectomy?

BackgroundAdvances in minimally invasive surgery and perioperative care have decreased substantially the duration of time that patients spend recovering in hospital, with many laparoscopic procedures now being performed on an ambulatory basis. There are limited studies, however, on same-day discharge after laparoscopic adrenalectomy. The objectives of this study were to investigate the outcomes and trends of ambulatory laparoscopic adrenalectomy in a multicenter cohort of patients.MethodsAdult patients who underwent elective laparoscopic adrenalectomy between 2005 and 2016 were identified in the database of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). Baseline demographics and 30-day outcomes were compared between patients who underwent ambulatory laparoscopic adrenalectomy and those who were discharged after an inpatient stay. Multivariable logistic regression and Cox proportional hazards modelling were used to investigate the association between same-day discharge and 30-day complications and unplanned readmissions.ResultsOf the 4,807 patients included in the study, 88 (1.8%) underwent ambulatory laparoscopic adrenalectomy and 4,719 (98.2%) were admitted after the adrenalectomy. The same-day discharge group contained fewer obese patients (37.2% vs 50%; P = .04), a lesser proportion of American Society of Anesthesiologists class III patients (45.5% vs 61%; P = .003), and more patients with primary aldosteronism (14.8% vs 6%; P = .002) compared with the inpatient group. After adjustment for confounders, same-day discharge was not associated with 30-day overall complications (OR 1.17, 95% CI 0.35–3.85; P = .80) or unplanned readmissions (HR 2.77, 95% CI 0.86–8.96; P = .09). The percentage of laparoscopic adrenalectomies performed on an ambulatory basis at hospitals participating in the ACS NSQIP remained low throughout the study period (0–3.1% per year) with no evidence of an increasing trend over time (P = .21).ConclusionAmbulatory laparoscopic adrenalectomy is a safe and feasible alternative to inpatient hospitalization in selected patients. Further study is needed to determine the cost savings, barriers to uptake, and optimal selection criteria for this approach.     

Melioidosis in a returned traveller

Melioidosis is an infection endemic to Southeast Asia and Northern Australia, and is associated with significant morbidity and mortality. The present report describes a case of chronic melioidosis in a returning traveller from the Philippines. Clinical suspicion of this illness is warranted in individuals with a history of travel to endemic regions. Safety in handling clinical specimens is paramount because laboratory transmission has been described.     

Epidemiology and Risk Factors for Bloodstream Infections in a Home Parenteral Nutrition Program

Background: An increasing number of patients with intestinal failure are receiving home parenteral nutrition (HPN). Associated complications include bloodstream infections (BSIs), but data on rates and risk factors for HPN‐related BSIs are scarce. Methods: A retrospective review was conducted of patients enrolled in the regional HPN program between 2001 and 2008. Demographic information and data on indication for HPN, duration of PN therapy, type and date of insertion of central venous access device, and blood culture results were recorded. Results: In total, 155 patients (165 courses of HPN) were included for a total of 45,876 catheter days. The mean patient age was 49 years, and 105 (64%) patients were female. A total of 105 organisms were cultured from 93 distinct episodes of BSIs. The rate of BSI was found to be 2.0 per 1000 catheter days, but excluding BSIs with a single positive culture of coagulase‐negative staphylococcus and diphtheroid bacilli, the rate of infection was 1.4 per 1000 catheter days. Male sex and underlying malignancy were significant predictors of BSI, with hazard ratios of 1.69 (95% confidence interval [CI], 1.14–2.60; P = .009) and 2.38 (95% CI, 1.53–3.50; P < .001). Conclusion: In a large heterogeneous group of HPN patients, the BSI rate ranged between 1.4 and 2.0 infections per 1000 catheter days. Isolated organisms were similar to those found in hospitalized patients. Male sex and underlying malignancy were significant risk factors for BSI. These high‐risk patients are likely to benefit from interventions aimed at reducing BSIs.     

Association between smoking and outcomes in older adults with atrial fibrillation

Tobacco smoking is a risk factor for atrial fibrillation (AF), but little is known about the impact of smoking in patients with AF. Of the 4060 patients with recurrent AF in the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial, 496 (12%) reported having smoked during the past two years. Propensity scores for smoking were estimated for each of the 4060 patients using a multivariable logistic regression model and were used to assemble a matched cohort of 487 pairs of smokers and nonsmokers, who were balanced on 46 baseline characteristics. Cox and logistic regression models were used to estimate the associations of smoking with all-cause mortality and all-cause hospitalization, respectively, during over 5 years of follow-up. Matched participants had a mean age of 70 ± 9 years (± S.D.), 39% were women, and 11% were non-white. All-cause mortality occurred in 21% and 16% of matched smokers and nonsmokers, respectively (when smokers were compared with nonsmokers, hazard ratio=HR=1.35; 95% confidence interval=95%CI=1.01-1.81; p=0.046). Unadjusted, multivariable-adjusted and propensity-adjusted HR (95% CI) for all-cause mortality associated with smoking in the pre-match cohort were: 1.40 (1.13-1.72; p=0.002), 1.45 (1.16-1.81; p=0.001), and 1.39 (1.12-1.74; p=0.003), respectively. Smoking had no association with all-cause hospitalization (when smokers were compared with nonsmokers, odds ratio=OR=1.21; 95%CI=0.94-1.57, p=0.146). Among patients with AF, a recent history of smoking was associated with an increased risk of all-cause mortality, but had no association with all-cause hospitalization.     

Efficacy of metformin in the management of periodontitis: A systematic review and meta-analysis

Periodontitis is characterized by inflammation of the periodontium and leads to loss of teeth if untreated. Although a number of surgical and pharmacological options are available for the management of periodontitis, it still affects a large proportion of population. Recently, metformin (MF), an oral hypoglycemic, has been used to treat periodontitis. The aim of this review is to systematically evaluate the efficacy of MF in the treatment of periodontitis. An electronic search was carried out using the keywords ‘metformin’, ‘periodontal’ and ‘periodontitis’ via the PubMed/Medline, ISI Web of Science and Google Scholar databases for relevant articles published from 1949 to 2016. The addressed focused question was: ‘Is metformin effective in reducing bone loss in periodontitis? Critical review and meta-analysis were conducted of the results obtained in the selected studies. Following the removal of the duplicate results, the primary search resulted in 17 articles and seven articles were excluded based on title and abstract. Hence, 10 articles were read completely for eligibility. After exclusion of four irrelevant studies, six articles were included. The topical application of MF resulted in improved histological, clinical and radiographic outcomes. Additionally, results from the meta-analysis indicated that application of metformin improved the clinical and radiographic outcomes of scaling and root-planing, but at the same time heterogeneity was evident among the results. However, because of a lack of histological and bacterial studies, in addition to short follow-up periods and risk of bias, the long-term efficacy of MF in the treatment of bony defects is not yet ascertained. Further studies are needed to envisage the long-term efficacy of MF in the management of periodontitis.     

Antidiabetic drugs and non-alcoholic fatty liver disease: A systematic review,meta-analysis and evidence map

BackgroundThe efficacy of antidiabetic agents for the treatment of non-alcoholic fatty liver disease (NAFLD) remains unclear.AimTo conduct a meta-analysis to study the efficacy of pioglitazone and three novel anti-diabetic agents: glucagon-like peptide-1 (GLP-1) agonists, sodium-glucose co-transporter-2 (SGLT2) inhibitors, and dipeptidyl-peptidase-4 (DPP4) inhibitors in treating NAFLD.MethodsOnline databases were searched in May 2020 for randomized clinical trials. Results from random-effects meta-analysis are presented as weighted mean differences (WMDs) or standard mean differences (SMDs) and corresponding 95% confidence intervals (CIs).ResultsTwenty-six studies (n=946 NAFLD patients) were included. Reductions in ALT were seen with all four drugs: pioglitazone (MD -38.41, p<0.001), SGLT2 inhibitors (MD -16.17, p<0.001), GLP-1 agonists (MD -27.98, p=0.04) and DPP-4 inhibitors (MD -7.41, p<0.001). Pioglitazone (SMD -1.01; p<0.001) and GLP-1 agonists (SMD -2.53, p=0.03) also demonstrated significant improvements in liver steatosis. SGLT2 inhibitors (SMD -4.64, p=0.06) and DPP-4 (SMD -2.49, p=0.06) inhibitors trended towards reduced steatosis; however, these results were non-significant.ConclusionPioglitazone demonstrates significant improvements in transaminases and liver histology in both diabetic and non-diabetic NAFLD patients. Early evidence from diabetic NAFLD patients suggests that novel antidiabetics may lead to improvements in liver enzymes and hepatic steatosis, and this should encourage further research into possible utility of these drugs in treating NAFLD.
