Thyroidectomy

This article discusses the procedure and technique for performing a thyroidectomy: explaining complications, potential pitfalls and methods of avoiding them. We also discuss the indications for surgery and the preparation required especially for thyrotoxic patients and those with retrosternal goitres. We also discuss the ever increasing issues with consent and how thyroid surgeons are monitored in the UK.     

A randomised controlled trial of placebo,droperidol or ondansetron to prevent nausea and vomiting after tonsillectomy in children receiving dexamethasone

We tested whether prophylactic droperidol and ondansetron, in combination with a moderate dose of dexamethasone, were equally effective in reducing nausea and vomiting after tonsillectomy in children and that both were superior to saline with dexamethasone. We randomly allocated 300 children to intravenous saline, droperidol 10 μg.kg^?1 or ondansetron 150 μg.kg^?1, after induction of anaesthesia and the administration of intravenous dexamethasone 250 μg.kg^?1. The rates (95%CI) of nausea or vomiting within 24 postoperative hours were: 42/91 after saline, 46% (36%–57%); 43/87 after droperidol, 49% (39%–60%); reduced to 18/84 by ondansetron, 21% (13%–32%), p < 0.001. There were no differences in the rates of side‐effects between groups. We conclude that ondansetron is more effective than saline in preventing nausea or vomiting after paediatric tonsillectomy when given with a moderate dose of dexamethasone, whereas droperidol was not.     

Change of transfusion and treatment paradigm in major trauma patients

Trauma promotes trauma‐induced coagulopathy, which requires urgent treatment with fixed‐ratio transfusions of red blood cells, fresh frozen plasma and platelet concentrates, or goal‐directed administration of coagulation factors based on viscoelastic testing. This retrospective observational study compared two time periods before (2005–2007) and after (2012–2014) the implementation of changes in trauma management protocols which included: use of goal‐directed coagulation management; admission of patients to designated trauma centres; whole‐body computed tomography scanning on admission; damage control surgery; permissive hypotension; restrictive fluid resuscitation; and administration of tranexamic acid. The incidence of massive transfusion (≥ 10 units of red blood cells from emergency department arrival until intensive care unit admission) was compared with the predicted incidence according to the trauma associated severe haemorrhage score. All adult (≥ 16 years) trauma patients primarily admitted to the University Hospital Zürich with an injury severity score ≥ 16 were included. In 2005–2007, the observed and trauma associated severe haemorrhage score that predicted the incidence of massive transfusion were identical, whereas in 2012–2014 the observed incidence was less than half that predicted (3.7% vs. 7.5%). Compared to 2005–2007, the proportion of patients transfused with red blood cells and fresh frozen plasma was significantly lower in 2012–2014 in both the emergency department (43% vs. 17%; 31% vs. 6%, respectively), and after 24 h (53% vs. 27%; 37% vs. 16%, respectively). The use of tranexamic acid and coagulation factor XIII also increased significantly in the 2012–2014 time period. Implementation of a revised trauma management strategy, which included goal‐directed coagulation management, was associated with a reduced incidence of massive transfusion and a reduction in the transfusion of red blood cells and fresh frozen plasma.     

Postępowanie w udarze mózgu – wytyczne Grupy Ekspertów Sekcji Chorób Naczyniowych Polskiego Towarzystwa Neurologicznego. Aktualizacja 2013: leczenie trombolityczne

Thrombolysis is the most effective therapy for ischaemic stroke. The current guidelines and approvals have limited its use to patients available for treatment within 4.5 hours of onset and those aged 80 or less. There are also a number of other limitations derived from clinical trial protocols, i.e. minor and major strokes. The available evidence has indicated its possible efficacy in patients treated within 6 hours of onset and not fulfilling other limitations.Last year, the results of the IST-3 (Third International Stroke Trial: Thrombolysis) and a meta-analysis of all available trials including IST-3 were published. They point out the possible benefit of thrombolysis in patients not meeting the current criteria, which has been acknowledged in the Polish guidelines for management of stroke.     

Intravenous immunoglobulin therapy: New aspects and outlook

Summary Experiences gathered while exploring the usefulness of intravenous immunoglobulin for children with idiopathic (immune) thrombocytopenic purpura (ITP) are reviewed in view of further investigations characterizing the effects of IgG i.v. in other immune diseases without detectable antibody deficiency. The most pertinent factors to be considered are i) the heterogeneity of an immune disease investigated; ii) the criteria used to evaluate the effects of the IgG therapy; iii) the IgG preparations used and i.v. dose-fractionation. Controlled, prospective clinical trials will be required to further explore the practical usefulness of IgG i.v.     

Temporomandibular joint surgery: what does it mean to the dental practitioner?

A poor appreciation of the role of surgery in the management of temporomandibular disorders (TMD) may result in some patients being denied access to appropriate care. While surgery is often considered as an option of last resort, there are instances where surgery is the definitive and sometimes the only treatment option. The aim of this paper was to review the role of temporomandibular joint (TMJ) surgery and its place in the treatment armamentarium of temporomandibular disorders. Indications, rationale for surgery, risks vs. benefits are discussed and complemented with examples of clinical cases treated by the author. All dental practitioners should be aware of the benefits of TMJ surgery so that patients do not suffer unnecessarily from ongoing non-surgical treatments that ultimately prove to be ineffective in the management of their condition.     

Risk factors to discriminate neoplastic polypoid lesions of gallbladder: A large-scale case-series study

BackgroundPolypoid lesion of gallbladder (PLG) size larger than 10 mm is considered to be one of the surgical indications, but the final pathological results are mostly non-neoplastic polyps. The aim of the study was to define the risk factors to discriminate neoplastic PLG and create more precise criteria for surgical indications.MethodsA large scale, case-series study based on 2704 patients who underwent cholecystectomy for PLG was designed. Logistic regression analysis and receiver operating characteristic curve (ROC) was adopted to identify risk factors and the optimal size criteria for predicting neoplastic PLG.ResultsPatients in the neoplastic group were significantly older than those in the non-neoplastic group and the average PLG size is much larger in the neoplastic group (18.5 ± 4.7 mm vs 12.6 ± 3.6 mm). Neoplastic PLGs are prone to be single and non-neoplastic polyps are usually multiple. On Multivariate logistic regression analysis, PLG size larger than 15 mm and age older than 43 years were found to be the independent risk factors to discriminate neoplastic PLG （Odds ratio 3.546 and 2.77 respectively）. The ROC curve showed that 12 mm might be the more reasonable PLG size threshold for the surgical suggestion.ConclusionsConsidering its moderate diagnostic accuracy, the size of gallbladder polyp larger than 10 mm is insufficient to indicate surgical therapy for PLG and 12 mm should be the more optimal polyp's size threshold. Patients older than 43 years have a higher risk of having neoplastic polyps.     

Patient Functional Status as an Indication for Primary Total Hip Arthroplasty: A Systematic Review and Meta-Analysis

BackgroundThe number of total hip arthroplasties performed per year is increasing for reasons not fully explained by a growing and aging population. The purpose of this study was to determine the role of patient functional status as an indication for surgery and determine if patients are undergoing surgery at a better functional status than in the past.MethodsA systematic review and meta-analysis of the MEDLINE, EMBASE, and Cochrane databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Functional status was assessed using the 36-Item Short-Form Health Survey’s Physical Component Summary score. Only primary procedures were included; revisions were excluded. Articles were screened by 2 independent reviewers with conflicts resolved with a third reviewer. Meta-regression analysis was performed to determine the effect of time, patient age, and gender. Subgroup analysis was performed to compare geographic regions.ResultsA total of 1504 articles were identified. Data from 172 groups representing 18,644 patients recruited from 1990 to 2013 and identified from 107 articles were included. The mean preoperative Physical Component Summary score was 31.2 (95% confidence interval 30.5-31.9) with a 95% prediction interval of 22.6-39.8. The variance across studies was statistically significant (P = .000) with 97.25% true variance. Year of enrollment, age, and the percentage of females were not found to have any significant effect. There were no differences between countries.ConclusionPatients are undergoing total hip arthroplasty at a similar preoperative physical functional status as in the past. Patient age, gender, and location do not influence the functional status at which patients are indicated for surgery.
