Article Synopsis
  • Periarticular knee fractures happen around the knee and include broken bones in the femur, tibia, and patella, making up 5%-10% of injuries treated in hospitals.
  • These fractures are often complicated and require surgery to fix the knee's surface and ensure proper alignment and movement.
  • Doctors use special CT scans to understand the fracture better and decide on the best surgical treatment, considering different types of fractures and their effects on the knee.

Introduction: Opioid overprescribing has caused a substantial increase in opioid related deaths and billions of dollars in additional healthcare costs. Orthopaedic surgeons commonly prescribe opioids in the perioperative period; however, research has shown preoperative opioid use may be associated with worse postoperative outcomes. Despite this body of evidence, there are few studies investigating the association between preoperative opioid use and two-year outcomes after hand surgery.

Introduction: Breast-conserving therapy (BCT), specifically breast-conserving surgery (BCS) and adjuvant radiation, provides an equivalent alternative to mastectomy for eligible patients. However, previous studies have shown that BCT is underused in the United States, particularly among marginalized demographic groups. In this study, we examine the association between race, ethnicity, insurance, and language and rate of BCS among patients treated at an academic, safety-net hospital.

Stereotactic ablative radiotherapy (SABR) has been increasingly used for the treatment of inoperable early-stage non-small cell lung cancer (NSCLC). It has been shown to provide promising local control (LC) and toxicity in prospective trials. However, randomized trials have shown conflicting results in terms of whether SABR confers an overall survival (OS) advantage compared to conventionally fractionated radiotherapy (CFRT).

Background:  Surgical repair is indicated for patellar tendon ruptures that result in loss of knee extensor mechanism function. However, biomechanical studies report conflicting results when comparing transosseous suture versus suture anchor repair techniques. This discrepancy may be due to inconsistencies in experimental design as these studies use various numbers of suture strands.

Purpose: Among women with non-metastatic breast cancer, marked disparities in stage at presentation, receipt of guideline-concordant treatment and stage-specific survival have been shown in national cohorts based on race, ethnicity, insurance and language. Little is published on the performance of safety-net hospitals to achieve equitable care. We evaluate differences in treatment and survival by race, ethnicity, language and insurance status among women with non-metastatic invasive breast cancer at a single, urban academic safety-net hospital.

Article Synopsis
  • Hyperammonemic encephalopathy (HE) is a severe complication seen in multiple myeloma patients, with this case being notable as it involves a rare form called non-producer multiple myeloma (NPMM) that typically lacks immunoglobulin production.
  • A 60-year-old male patient experienced lethargy that progressed to a coma, linked to an elevated ammonia level despite normal liver function, leading to a diagnosis of HE caused by NPMM.
  • Treatment with a combination of chemotherapy drugs effectively resolved the HE, and the case suggests that the mechanism behind ammonia buildup in NPMM involves altered amino acid metabolism in the cancer cells, rather than the breakdown of M-proteins as previously thought.

Article Synopsis
  • Long QT syndrome (LQTS) is a genetic heart condition that disrupts normal electrical activity, which can result in serious symptoms like fainting, seizures, and even sudden death.
  • Researchers created two human-induced pluripotent stem cell (iPSC) lines from patients with a specific mutation in the SNTA1 gene linked to LQTS.
  • These iPSC lines displayed normal characteristics and potential to develop into various cell types, making them useful for studying the disease mechanisms associated with the SNTA1 mutation.

Background: Disparities in breast reconstruction have been observed in national cohorts and single-institution studies based on race, ethnicity, insurance, and language. However, little is known regarding whether safety-net hospitals deliver more or less equitable breast reconstruction care in comparison with national cohorts.

Study Design: We performed a retrospective study of patients with either invasive breast cancer or ductal carcinoma in situ diagnosed and treated at our institution (January 1, 2009, to December 31, 2014).

The Press Ganey Ambulatory Surgery (PGAS) survey is an emerging tool used to capture patient satisfaction after elective surgery. Evaluating patient satisfaction is important; however, quality improvement (QI) surveys used to capture the patient experience may be subject to nonresponse bias. An orthopaedic registry was used to retrospectively identify patients who underwent ambulatory knee surgery from June 2015 to December 2019.

Background: Contextualizing patient-reported outcomes (PROs) by defining clinically relevant differences is important. Considering that anterior cruciate ligament reconstruction (ACLR) ideally results in the restoration of normal knee function, an assessment of patients' perception of being "completely better" (CB) may be of particular value.

Purpose: The purpose of this study was to assess the prevalence and characteristics of patients who self-report a CB status after ACLR.
