Safety aspects of preoperative high-dose glucocorticoid in primary total knee replacement

Abstract

Background: Preoperative single high-dose glucocorticoid may have early outcome benefits in total hip arthroplasty (THA) and knee arthroplasty (TKA), but long-term safety aspects have not been evaluated.Methods: From October 2013, the departments reporting to the prospective Lundbeck Foundation Database for Fast-track Hip and Knee Replacement introduced preoperative methylprednisolone (MP) 125 mg as part of a multimodal analgesic protocol in TKA. We analysed the risk of length of hospital stay (LOS) >4 days, 30 and 90 day readmissions in patients with MP vs patients having TKA before the use of MP and adjusted for comorbidity and place of surgery. An unadjusted comparison was specifically done to evaluate deep prosthetic infections.Results: Of a total of 3927 TKA procedures, 1442 received MP. Median LOS was 2 days in both groups, but the fraction with LOS >4 days was 6.0% vs 11.5% (P<0.001) in patients with MP vs those without, and with a reduced risk of LOS >4 days in adjusted analysis [odds ratio (OR) 0.51; confidence interval (CI) 0.39–0.68; P<0.001]. Readmission rates were 5.6% (CI 4.5–6.9) vs 4.4% (P=0.095) and 7.8% vs 7.3% (P=0.53) at 30 and 90 days with and without MP, respectively.Adjusted analysis did not identify MP to be associated with 30 day (OR 1.18; CI 0.89–1.56; P=0.25) or 90 day (OR 1.12; CI 0.86–1.46; P=0.39) readmissions. The incidence of deep infections requiring surgical intervention was 0.8% vs 0.7% with MP vs without, respectively (P=0.78).Conclusions: In this detailed prospective cohort study, preoperative high-dose glucocorticoid administration was not associated with LOS >4 days, readmissions or infectious complications in TKA patients without contraindications.Clinical trial registration: NCT01515670.

Endoscopic versus microscopic type 1 tympanoplasty in the same patients: a prospective randomized controlled trial

Abstract

The aim of this study was to compare the audiologic outcomes of the patients who underwent endoscopy on one ear and microscopic tympanoplasty on the other, and to investigate the operative time, graft success, postoperative pain and health status. This prospective randomized controlled study was carried out in Ege University ENT Department between February 2015 and September 2016. The patients who had bilateral chronic otitis media, normal middle ear mucosa and a hearing loss difference of 10 dB or less between the two ears randomly underwent microscopic tympanoplasty in one ear and endoscopic tympanoplasty in the contralateral ear, with 6-month intervals. 13 patients were included in the study with a mean age of 36.17 ± 3.61 years (range 17–53 years, 7 female, 6 male). The improvement in air–bone gap for groups 1 (endoscopic) and 2 (microscopic) was 9.48 ± 5.23 and 9.89 ± 2.79 dB, respectively. The duration of the surgery in group 1 was significantly lower than that in group 2 (p < 0.01). VAS scores were 2.15 ± 0.37 and 3.76 ± 1.64 cm for groups 1 and 2, respectively (p = 0.006). The endoscopic approach for type 1 tympanoplasty offers shorter surgery time, better health status and lower postoperative pain than microscopic surgery. In addition, endoscopic surgery offers comparable improvement in air–bone gap and similar graft success. The endoscopic approach has comparable audiological and morphological graft outcomes with the microscopic one. The endoscopic approach yielded better health and pain status for the same patients.

Level of evidence This is an individual randomized controlled trial. The level of evidence is 1b.

Polymorphisms in DENND1B gene are associated with asthma and atopy phenotypes in Brazilian children

Asthma is a heterogeneous disease associated with a complex basis involving environmental factors and individual variabilities. The DENN Domain Containing 1B (DENND1B) gene has an important role on T cell receptor (TCR) down-regulation on Th2 cells and studies have shown that mutations or loss of this factor can be associated with increased Th2 responses and asthma. The aim of this work is to evaluate the association of polymorphisms in the DENND1B with asthma and allergy markers phenotypes in Brazilian children. Genotyping was performed using a commercial panel from Illumina (2.5 Human Omni bead chip) in 1309 participants of SCAALA (Social Change, Asthma, Allergy in Latin American) program. Logistic regressions for asthma and atopy markers were performed using PLINK software 1.9. The analyzes were adjusted for sex, age, helminth infections and ancestry markers. The DENND1B gene was associated with different phenotypes such as severe asthma and atopic markers (specific IgE production, skin prick test and IL-13 production). Among the 166 SNPs analyzed, 72 were associated with asthma and/or allergy markers. In conclusion, polymorphisms in the DENND1B are significantly associated with development of asthma and atopy and these polymorphisms can influence DENND1B expression and consequently, asthma.
