Alopecia areata is an autoimmune, nonscarring, multifocal disorder of hair growth characterized by circular bald areas, which occur on any hair bearing site of the body. The exact cause of alopecia areata is unknown. Recent study reported a potential role of oxygen free radicals (OFR) in pathogenesis of alopecia areata. This clinical study was designed to evaluate the antioxidant effect of melatonin (3 mg every other day ) in patients with alopecia areata. This study revealed that two month treatment with melatonin antioxidant led to a decrease in the basal level of malondialdehyde (MDA) an index of lipid peroxidation, an increase in basal glutathione (GSH) content a major endogenous antioxidant in both plasma and erythrocytes and an increase in plasma total antioxidant status( TAS ) . The most important point is the clinical significance of antioxidants in improving the hair growth response of patients with alopecia areata. This may be due to direct and/or indirect effect of melatonin on immune system. The direct effect may be through its immunoenhancing / immunostimulatory properties of melatonin.The indirect effect is the scavenging activity of this antioxidant, which in turn decrease damaging effect of oxygen free radicals (OFR) and utilization of GSH in neutralizing phagocytes- induced free radicals. So replenishment of GSH within natural killer (immune) cells strengthens the immune system and increases the rate of hair growth.

People with alopecia areata lose their scalp hair in smooth round patches typically causing bald spots about an inch (2cm) across. Recently Al-Jaff et al demonstrate the association of free radicals in the pathogenesis of alopecia areata, and the role of nutrient antioxidants in protecting the immune system from the damaging effect of these radicals.Any imbalances between free radical production and antioxidant deficiency can result in an injury. This clinical study designed to study the role of nutrient antioxidants in protecting the body from damaging effect of radicals and the effect of two month treatment with antioxidants (vitamin A, E, &C) on oxidative stress variable levels and their effect on rate of hair growth in patients with alopecia areata. Treatment with antioxidants significantly elevated body antioxidant defenses component levels, increased Zn levels and decreased Cu levels and corrected the inbalance in these trace metals metabolism in alopecia after 1and 2 months of treatment compared to pretreatment values. The most important point is the clinical significance of antioxidants in improving the hair response of patients with alopecia areata; this may be due to an inhibition of oxidative stress associated with the state of the disease.

Alopecia areata is a nonscarring hair -loss condition that often has a patchy distribution and can be quite unpredictable.

Purpose: An extended length of stay following open reduction and internal fixation (ORIF) for proximal humerus fractures (PHFs) is associated with increased patient morbidity and health care costs. The primary purpose of this study was to identify risk factors for an extended length of stay following ORIF for PHF., Methods: All patients who underwent ORIF for PHF between 2015 and 2021 were queried from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Patient demographics, comorbid conditions, and postoperative complications within 30 days of procedure were collected. Extended length of stay (eLOS) was defined by ≥ 3 days from operation to discharge. Multivariate logistic regression was employed to identify predictors of eLOS following ORIF., Results: Characteristics of patients significantly associated with eLOS included age ≥ 75 years (p < .001), male gender (p < 0.001), body mass index (BMI) < 18.5 ( P  = .001), American Society of Anesthesiologists (ASA) classification ≥ 3 ( P < .001), dependent functional status ( P < .001), noninsulin-dependent diabetes ( P  = .037), insulin-dependent diabetes ( P < .001), chronic obstructive pulmonary disease ( P < .001), congestive heart failure (CHF) ( P < .001), hypertension ( P < 0.001), dialysis ( P < .013), disseminated cancer ( P < 0.001), chronic steroid use ( P  = .004), and bleeding disorder ( P < .001). Independent predictors of eLOS were age ≥ 75 years (OR = 2.69; P < .001), BMI < 18.5 (OR = 1.70; P  = .016), ASA ≥ 3 (OR = 2.70; P < .001), dependent functional status (OR = 2.30; P < .001), CHF (OR = 3.57; P < .001), disseminated cancer (OR = 7.62; P < .001), and bleeding disorder (OR = 2.68; P < .001)., Conclusion: Age ≥ 75, BMI < 18.5, ASA ≥ 3, functional dependence, CHF, disseminated cancer, and bleeding disorder were independently associated with eLOS., Clinical Relevance: Assessing specific patient factors prior to ORIF for PHF can assist in managing perioperative risks and decreasing expenses related to eLOS., Level of Evidence: Prognosis III., (© 2023 The Authors.)

Background: The purpose of this study was to investigate the association between preoperative platelet count and 30-day postoperative complications following arthroscopic rotator cuff repair (aRCR)., Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent aRCR between 2015 and 2021. The study population was divided into 5 groups based on preoperative platelet count: normal (200-450k, reference cohort), low-normal (150-200k), mild thrombocytopenia (100-150k), moderate-to-severe thrombocytopenia (<100k), and thrombocytosis (>450k). Thirty-day postoperative complications following aRCR were collected. Multivariate logistic regression analysis was conducted to investigate the relationship between preoperative platelet counts and postoperative complications., Results: 24,779 patients were included in this study: 18,697 (75.5%) in the normal group, 4730 (19.1%) in the low-normal group, 1012 (4.1%) in the mild thrombocytopenia group, 171 (0.7%) in the moderate-to-severe thrombocytopenia group, and 169 (0.7%) in the thrombocytosis group. Low-normal platelets were an independent predictor of urinary tract infection (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.12-3.77; P  = .020). Mild thrombocytopenia was not an independent predictor of any complications. Moderate-to-severe thrombocytopenia was an independent predictor of sepsis (OR 9.39, 95% CI 1.48-59.47; P  = .017), pneumonia (OR 6.62, 95% CI 1.32-33.24; P  = .022), and nonhome discharge (OR 3.34, 95% CI 1.20-9.25; P  = .021). Thrombocytosis was an independent predictor of urinary tract infection (OR 4.91, 95% CI 1.16-20.78; P  = .030)., Conclusion: Abnormal preoperative platelet counts, both low and high, were independent risk factors for 30-day postoperative complications following aRCR., (© 2023 The Author(s).)

Purpose: The incidence of distal radius fractures (DRFs) in the United States is more than 640,000 cases per year and is projected to increase. The overall prevalence of anemia in the United States increased from 5.71% in 2005 to 6.86% in 2018. Therefore, preoperative anemia may be an important risk factor to consider before surgical fixation of a distal radius fracture. The purpose of this study was to investigate preoperative anemia and its association with short-term complications after surgical treatment of DRFs., Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent open reduction internal fixation (ORIF) of DRFs between 2015 and 2020. The initial pool of patients was divided into cohorts based on preoperative hematocrit. Multivariate logistic regression, adjusted for all significantly associated patient demographics and comorbidities, was used to identify associations between preoperative anemia and postoperative complications after ORIF of DRFs., Results: A total of 22,923 patients who underwent ORIF of DRFs were identified in National Surgical Quality Improvement Program from 2015 to 2020. Of the 12,068 patients remaining after exclusion criteria, 9,616 (79.7%) patients were included in the normal cohort, 2,238 (18.5%) patients were included in the mild anemia cohort, and 214 (1.8%) patients were included in the severe anemia cohort. Compared with the reference cohort, patients with any anemia were independently associated with higher rates of reintubation (odds ratio [OR], 6.51; 95% confidence interval [CI], 1.29-32.80; P  = .023), blood transfusion (OR, 11.83; 95% CI, 3.95-35.45; P < .001), septic shock (OR, 10.76; 95% CI, 1.19-97.02; P  = .034), readmission (OR, 2.10; 95% CI, 1.60-2.76; P < .001), nonhome discharge (OR, 2.22; 95% CI, 1.84-2.68; P < .001), and mortality (OR, 2.70; 1.03-7.07; P  = .043)., Conclusions: Preoperative anemia, both mild and severe, were clinically significant predictors for postoperative complications within 30-day after ORIF of DRFs. Severe anemia was associated with higher rates of blood transfusion, nonhome discharge, and mortality compared with mild anemia., Type of Study/level of Evidence: Prognostic III., (© 2023 The Authors.)

Background: The purpose of this study was to investigate the association between in-hospital length of stay (LOS) and postoperative complication rates within 30 days of total shoulder arthroplasty (TSA)., Methods: All patients who underwent either anatomic or reverse TSA between 2015 and 2019 were queried from the American College of Surgeons National Surgical Quality Improvement database. The study population was stratified into three cohorts as follows: LOS 0 (same-day discharge), LOS 1 (next-day discharge), and LOS 2-3 (LOS of 2-3 days). Patient demographics and comorbidities were compared between cohorts using bivariate analysis. Multivariate logistic regression analysis was conducted to investigate the relationship between LOS and postoperative complications., Results: In comparison to the LOS 0 day cohort, LOS 2-3 day cohort had a greater likelihood of developing overall complication (OR, 2.598; P  < .001), major complication (OR, 1.885; P  < .001), minor complication (OR: 3.939; P  < .001), respiratory complication (OR: 12.979; P  = .011), postoperative anemia requiring transfusion (OR, 23.338; P  < .001), non-home discharge (OR, 10.430; P  < .001), and hospital readmission (OR, 1.700; P  = .012). Similarly, in comparison to the LOS 1 cohort, LOS 2-3 cohort had a greater likelihood of developing overall complication (OR: 2.111; P  < .001), major complication (OR, 1.423; P  < .001), minor complication (OR, 3.626; P  < .001), respiratory complication (OR, 2.057; P  < .001), sepsis or septic shock (OR: 2.795; P  = .008), urinary tract infection (OR, 1.524; P  = .031), postoperative anemia requiring transfusion (OR, 10.792; P  < .001), non-home discharge (OR: 10.179; P  < .001), hospital readmission (OR, 1.395; P  < .001), and return to the operating room (OR. 1.394; P  = .014). There was no significant difference in the risk of developing postoperative complications between LOS 0 day and LOS 1 day cohort. On baseline, the LOS 1 and LOS 2-3 day cohort had a higher proportion of patients with the following demographics and comorbidities compared to LOS 0 day cohort: advanced age, higher body mass index, female gender, positive smoking status, insulin-dependent diabetes, noninsulin-dependent diabetes, dyspnea at rest and moderate exertion, partially dependent functional status, an American Society of Anesthesiologists classification of 3 or higher, a history of severe chronic obstructive pulmonary disease, a history of congestive heart failure, the use of hypertension medication, disseminated cancer, wound infection, the use of steroids, and a history of bleeding disorder., Conclusion: Patients who were discharged on the same and next day following TSA demonstrated a reduced probability of experiencing respiratory complications, infections, postoperative anemia requiring transfusion, non-home discharge, and readmission in comparison to those with a LOS of 2-3 days. There was no difference in postoperative complications between same and nextday discharged patients. Patients who underwent outpatient arthroplasty were healthier at baseline compared to those who underwent inpatient arthroplasty., (© 2023 The Author(s).)

Background: Rotator cuff tears are a common injury encountered by orthopedic surgeons. Reverse shoulder arthroplasty (RSA) has become a treatment option for those with acute tears, as well as those with prior failed rotator cuff repair (RCR). The objective of this study was to determine if there are differences in postoperative outcomes for patients with previous RCR compared to those undergoing primary RSA for rotator cuff tears., Methods: A comprehensive literature search was conducted using PubMed, EMBASE, Scopus, and Cochrane Library databases. All relevant studies were reviewed by two authors according to inclusion and exclusion criteria defined in the study. Demographics and postoperative outcomes including functional scores, range of motion, pain scores, and complications were recorded., Results: Six level III articles encompassing 2176 shoulders were included in the analysis (846 with previous RCR and 1330 without). Average postoperative American Shoulder and Elbow Surgeons scores were 75.41 in the prior RCR group and 81.61 in the group without prior repair (mean difference [MD] = -5.95, P ≤ .0001 I 2  = 36). Average postoperative Simple Shoulder Test scores were 8.40 in the RCR group and 9.57 in the group without prior RCR (MD = -0.93, P ≤ .0001, I 2  = 66). Average postoperative Constant Score was 62.97 in the RCR group and 66.63 in the group without prior RCR (MD = -5.02, P ≤ .0001, I 2 ≤ 0.001). Average postoperative University of California at Los Angeles Shoulder Scale score was 28.27 in the RCR group and 29.13 in the group without prior RCR (MD = -1.75, P ≤ .001, I 2 ≤ 0.001). Average postoperative visual analog scale pain score was 1.77 in the RCR group and 0.95 in the group without prior RCR (MD = 0.75, P ≤ .0001, I 2  = 35)., Conclusion: Patients with prior RCR undergoing RSA have worse postoperative functional scores and pain scores than those without prior RCR. However, these differences are below the minimal clinically important difference for each outcome., (© 2023 The Authors.)

Negligence claims in the UK NHS has increased over the last 30 years. The aim of this present study was determine the number of claims and the cost of litigation in Bariatric Surgery and compare it to similar other specialties. Data was received from NHS Litigation Authority (NHSLA) in response to Freedom of Information data request. There was a total of 7 claims, of which 4 were successful. The total pay out sum was £210,000 in 10 years. This is a very low amount compared to other surgical specialties. This low level of litigation probably indicates that the current bariatric surgical services in the NHS are delivering safe care with good patient satisfaction. This needs to be carefully considered prior to changing the payment tariffs for bariatric surgery., (Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.)
