Statin Use

In this single center, retrospective cohort study we wished to compare early and total mortality for all patients treated for abdominal aortic aneurysms (AAA) with open surgery who were taking statins compared to those who were not. A cohort of 640 patients with AAA was treated with open surgery between 1999 and 2012. Patients were consecutively recruited from a source population of 390,000; 21.3% were female, and the median age was 73 years. The median follow-up was 3.93 years, with an interquartile range of 1.79–6.58 years. The total follow-up was 2855 patient-years. An explanatory strategy was used. The propensity score (PS) was implemented to control for selection bias and confounders. The crude effect of statin use showed a 78% reduction of the 30-day mortality. A stratified analysis using the Mantel–Haenszel method on quintiles of the PS gave an adjusted effect of the odds ratio equal to 0.43 (95% CI: 0.18–0.96), indicating a 57% reduction of the 30-day mortality for statin users. The adjusted rate ratio was 0.62 (95% CI: 0.45–0.83), indicating a reduction of long-term mortality of 38% for statin users compared to non-users for a median follow-up of 3.93 years. This retrospective cohort study showed a significant beneficial effect of statin use on early and long-term survival for patients treated with open surgery. To be conclusive, our results need to be replicated by a randomized clinical trial.

Background: Use of general anaesthesia in outpatient invasive procedures has increased, especially in the field of dermatology. Being uncooperative, children often require general anaesthesia. Especially since surgical skin operations are painful and lengthy, dictating the use of general anaesthesia. Aim: The purpose of this study was to evaluate the safety, significant adverse events, and the complication rates related to general anaesthesia, when used among pediatric population underwent skin surgeries. Methods: We conducted a retrospective cohort study in the form of randomly selected patient chart review, with a surgical code in the array of 8,539–16,782 for 2 years. We reviewed registers to document any unexpected admissions, adverse events or complications. Surgical outcomes and anaesthesia complications were reviewed by three anaesthesia consultants. We conducted Inter-rater reliability test analysis and per cent agreement to determine the level of agreement between raters. Results: A total of 211 procedures were reported for 211 patients with 19 diagnoses. No adverse events related to anesthesia were recognized in any of those selected patients, apart from minor complications noticed in twelve patients (P value<0.03). Kappa value range between 0.78-1.00 (95% CI, 0.46809 to 1.00). Conclusion: In case of proper deploying of staff experience, appropriateness of choice of surgical procedure, patient selection, and modern technology as non-dependent confounding variables. Pediatric-trained anesthesiologists can safely use general anaesthesia in dermatological invasive procedures without significant complications.

Achilles Tendon Rupture

Abstract Background The best treatment for acute Achilles tendon ruptures remains controversial. No cohort studies have compared different immobilisation durations after open surgery. This retrospective cohort study aimed to determine the optimal duration of immobilisation after this surgery. Methods A total of 266 patients with acute Achilles tendon rupture were divided into 4 groups (A, B, C, and D) according to immobilisation duration of 0, 2, 4, and 6 weeks, respectively. All patients underwent the same suture technique with a similar rehabilitation protocol and were examined clinically at 2, 4, 6, 8, 10, 12, 14, 16, 24, and 48 weeks, with a final follow-up at a mean of 22.3 months postoperatively. The primary outcome was the time of return to light sports activity (LSA). Secondary outcomes included range of motion (ROM) and single-legged heel rise height (SHRH). Data on operation time, complications, visual analogue pain scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and Achilles tendon Total Rupture score (ATRS) were also collected. Demographic baseline data were analysed using one-way analysis of variance; outcome parameters were analysed using Kruskal-Wallis H test, and complications were analysed using Fisher’s exact test. Statistical significance was considered at P ≤ 0.05. Results VAS scores decreased significantly, reaching 0 in all groups after 12 weeks. The AOFAS and ATRS scores were significantly different between the groups from weeks 2 to 12 (P<0.001) and weeks 2 to 16 (P<0.001), respectively. All the mean scores showed better results in group B than in the other groups. In terms of recovery time of ROM, SHRH, and LSA, groups A and B were significantly faster than groups C and D (P<0.001). There were 13 (13/266, 4.9%) complications: 5 superficial infections, 3 deep venous thrombosis, and 5 trauma-related re-ruptures. On the last follow-up, all complications had recovered. There were no significant differences in complications between the groups. Conclusions Immobilisation for 2 weeks after this open surgery is the best choice for early rehabilitation and weight-bearing while minimising pain and other complications.
