[Congenital adrenal hyperplasia because of 11β-hydroxylase deficiency: past due diagnosis along with gender reassignment inside a two-year-old child].
Background Increasing total hip (THA) and knee (TKA) arthroplasties inevitably lead to accumulating failed arthroplasty (FA) with periprosthetic joint infections (PJI) and definite treatment recommendations are scarce. Our aims were to evaluate patient and infection site specific risk factors, and to identify case-dependent salvage procedure recommendations. Methods Retrospective analysis was conducted of salvage procedures for FA after PJI (amputation, Girdlestone resection arthroplasty [GRA], arthrodesis, or chronic fistulation [CF]) from 2008 to 2018. Univariable and multivariable modeling of revision and mortality rates, using cumulative incidence competing risk analysis, and Cox proportional hazards models were calculated. Results In total, 135 patients (THA 62%; TKA 38%) were diagnosed for FA after PJI, having undergone an average of 3 [1-4] revisions at a mean follow-up of 12.8 [7.8-20.9] years. Forty-four percent of THAs and 55% of TKAs had to be revised following FA, 44% deceased during follow-up, and 16% could be reconverted to an infection-free arthroplasty. GRA revealed significantly higher revision rates than CF (P = .015) for THA. Lower age (P = .003), higher number of revisions before FA (P = .007), more than one microorganism at infection site (P = .034), and GRA (P = .037, only THA) prevailed independent risk factors for revision. Patients' age remained an independent mortality risk factor (P = .001). Conclusion High-risk patients suffering from FA after THA with poor constitution profit from controlled constitution of CF, reducing the risk for revision surgeries and hospitalization. In case of FA after TKA, data did not allow definite treatment recommendations. We believe that education concerning amputation should be considered early after multiple TKA revisions.Background Total knee arthroplasty (TKA) is associated with increased risk of prolonged narcotic requirement compared to total hip arthroplasty (THA). This study aims to compare acute postoperative narcotic consumption between the 2 procedures and quantify amount of narcotics used by opioid prescribed. Methods From October 2017 to August 2019, patients were surveyed at 4-week follow-up to determine amount and duration of opioids used and whether they continued to require narcotics. click here Among 1332 patients who self-identified as opioid naïve, 670 underwent THA and 662 underwent TKA. Descriptive analysis was performed based on data type. Results The total morphine equivalent dose (MED) used in the postoperative period was lower in THA than in TKA (143 ± 160 vs 259 ± 250 MED, P less then .001). The duration of use was shorter, total amount of pills consumed was lower, and refill rates were less in THA compared to TKA regardless of which opioid was prescribed. A smaller proportion of patients required narcotics at 4-week follow-up in THA compared to TKA. A postoperative prescription of 45 pills of any one type of narcotic was sufficient for nearly 90% of THA patients, and 60 pills of any one type of narcotic was appropriate for over 75% of TKA patients. Conclusion THA is associated with less total narcotic consumption, shorter duration of use, less refills, and lower likelihood of requiring narcotics at 4-week follow-up. Percentiles of total narcotics consumed are provided to promote judicious postoperative prescribing patterns, and one could consider further reducing narcotics when utilizing our protocol, particularly for THA patients. Level of evidence This is a level III retrospective cohort study reviewing narcotic use in over 900 consecutive opioid-naïve patients undergoing total hip and knee arthroplasty.Background Advances in technique and perioperative blood management have improved transfusion rates following unilateral primary total joint arthroplasty and led some centers to change their preoperative blood ordering protocols. The purpose of this study is to determine whether deleting type and screens (T&S) from preoperative order sets was safe for patients undergoing primary total knee (TKA) and total hip arthroplasty (THA) and to identify patients who required allogenic blood transfusion. Methods Prospectively collected data were reviewed to identify any patient with a hemoglobin (Hgb) drawn within 30 days of surgery who received a transfusion following a unilateral primary TKA or THA. Results A total of 1255 patients met inclusion criteria. Of the total, 682 (54%) were TKAs and 573 (46%) were THAs. The mean preoperative Hgb was 11.5 g/dL with an average delta Hgb of 3.6 g/dL on postoperative day 1. No patient required an intraoperative transfusion. Fourteen patients (mean age and body mass index, 67.9 and 29.0) required a transfusion (1.1%) for postoperative blood loss anemia. Of those transfused, 13 (93%) of the patients underwent THA with the mean estimated blood loss of 378.6 mL. The total cost for a patient obtaining a T&S is $191.27. Conclusion In our series, the risk of blood transfusion was rare (1.1%) and occurred only secondary to postoperative blood loss anemia. There were no cases of intraoperative complication requiring urgent or emergent blood transfusion. Removing T&S from standard order sets for patients undergoing primary TKA or THA appears to be a safe and cost-effective practice.Background Patient knowledge about arthritis and risks, benefits, and outcomes of joint arthroplasty in developing countries is unknown. We evaluated the effectiveness of a preoperative class on improving knowledge and decreasing anxiety during a surgical mission trip offering total joint arthroplasty. Methods A team of US health care providers taught a preoperative class to 41 patients selected for total joint arthroplasty during a surgical mission trip to Guyana. Participants completed a 32-point survey about arthritis; indications, risks, and benefits of joint arthroplasty; and postoperative, in-patient rehabilitation expectations. The State-Trait Anxiety Inventory was used to measure participant anxiety. Participants completed identical surveys before and after class. Matched-pairs Student t tests were used to compare means between preclass and postclass surveys. Significance was accepted at P less then .05. Results Seventy-eight percent of patients (31 of 41) scored less than 12 of 32 possible points (40%) on the preclass knowledge questionnaire.
