Painful Peripheral Neuropathies of the Lower Limbs and/or Lower Extremities Treated with Spinal Cord Stimulation: A Systematic Review with Narrative Synthesis.

Introduction: Painful peripheral neuropathy (PPN) is a debilitating condition with varied etiologies. Spinal cord stimulation (SCS) is increasingly used when conservative treatments fail to provide adequate pain relief. Few published reviews have examined SCS outcomes in all forms of PPN.

Effect of a Delirium Screening Tool on Antipsychotic Medication Use in a Pediatric Intensive Care Unit.

Objective: Intensive care unit (ICU) delirium has been associated with increased length of hospital stay, morbidity, mechanical ventilation, and health care resource utilization. Antipsychotics are frequently used for ICU delirium management, despite a lack of robust evidence in the literature to support their benefit. Delirium screening may result in pharmacologic or non-pharmacologic treatment.

When to Perform Fusion Short of the Pelvis in Patients with Cerebral Palsy?: Indications and Outcomes.

Unlabelled: Patients with scoliosis secondary to cerebral palsy (CP) are often treated with posterior spinal fusion (PSF) with or without pelvic fixation. We sought to establish criteria to guide the decision of whether or not to perform fusion "short of the pelvis" in this population, and to assess differences in outcomes.

Methods: Using 2 prospective databases, we analyzed 87 pediatric patients who underwent PSF short of the pelvis from 2008 to 2015 to treat CP-related scoliosis and who had ≥2 years of follow-up.

Up and over: Consequences of raising the United States-Mexico border wall height.

Objectives: San Diego County's geographic location lends a unique demographic of migrant patients injured by falls at the United States-Mexico border. To prevent migrant crossings, a 2017 Executive Order allocated funds to increase the southern California border wall height from 10 ft to 30 ft, which was completed in December 2019. We hypothesized that the elevated border wall height is associated with increased major trauma, resource utilization, and health care costs.

Computed tomography of hyper-attenuated liver: Pictorial essay.

Demonstration of a very dense or hyper-attenuated liver on the pre-contrast CT images of the abdomen can be an unexpected finding. It may present as a diagnostic challenge if the underlying cause of it is not apparent from the provided clinical history. There are about 12 different pathologic conditions that are associated with deposition of radiopaque elements within the hepatic parenchyma, resulting in diffuse or multi-lobar hyperdense appearance of the liver on abdominal radiographs and CT.

Postpartum Acute Aortic Dissection in a Patient Without a Connective Tissue Disorder: A Case Report.

Type A acute aortic dissection is a rare life-threatening event that occurs most commonly in the third trimester or early postpartum and in women with connective tissue disorders. However, this case describes a type A aortic dissection diagnosed on postpartum day 2 in a woman with preeclampsia without a history of a connective tissue disease. The case emphasizes the importance of considering dissection in any parturient complaining of chest pain, especially in the setting of hypertension and a new murmur.

Utilization of TandemHeart in cardiogenic shock: Insights from the THEME registry.

Background: TandemHeart has been demonstrated to improve hemodynamic and metabolic complications in cardiogenic shock (CS). Contemporary outcomes have not been reported.

Objectives: To evaluate the outcomes of the TandemHeart (LivaNova) in contemporary real-world use.

Same-Day Discharge after Percutaneous Left Atrial Appendage Closure: Insights from the Nationwide Readmission Database 2015-2019.

Data on the feasibility of same-day discharge (SDD) following percutaneous left atrial appendage closure (LAAC) remain limited. We analyzed the US Nationwide Readmission Database from quarter four of 2015 to 2019 to study the safety and feasibility of SDD after LAAC. After excluding non-elective cases and in-hospital deaths, a total of 54,880 cases of LAAC were performed during the study period.

Proximal reflux frequency not correlated with atypical gastroesophageal reflux disease (GERD) symptoms.

Though most known for heartburn and regurgitation, gastroesophageal reflux disease (GERD) is attributed to countless atypical, extra-esophageal (EE) manifestations like cough and throat clearing. While GERD has been studied extensively, the relationship between reflux character and symptom manifestation remains poorly understood. The aim of this study was to examine proximal reflux frequency and its relationship with typical or atypical symptoms.

A fluorescent photoimmunoconjugate for imaging of cholesteatoma.

Cholesteatoma is a potentially serious complication of chronic ear infections and requires surgical intervention for definitive management. Long-term complications include a frequent need for repeat surgical intervention for disease recurrence, and techniques to improve efficacy of single-stage surgery are an important area of continued research. This study investigates a novel application of the photosensitizer immune conjugate (PIC) cetuximab-benzoporphyrin derivative (Cet-BPD) for in vitro localization of human cholesteatoma tissue, coupled with an in vivo safety study for middle ear application of Cet-BPD in a murine model.

Imaging congenital anomalies of the ileum in adults:a pictorial review.

The ileal loops are anatomical location for the majority of congenital anomalies affecting the gastrointestinal tract. These include Meckel's diverticulum, ileal duplication, dysgenesis, atresia, mucosal diaphragm, and malposition of the ileum. Symptomatic lesions that often present with abdominal pain, intestinal obstruction or bleeding are usually diagnosed and treated during infancy and childhood.

Temporary Epicardial Pacing After Cardiac Surgery.

Temporary epicardial pacing frequently is employed after cardiac surgery, and can have a significant impact on a patient's hemodynamics, arrhythmias, and valvulopathies. Given that anesthesiologists often are involved intimately in the initial programming and subsequent management of epicardial pacing in the operating room and intensive care unit, it is important for practitioners to have a detailed understanding of the modes, modifiable intervals, and potential complications that can occur after cardiac surgery. Because this topic has not been reviewed recently in anesthesia literature, the authors attempted to review relevant epicardial pacemaker specifics, discuss modes and parameters that apply to the perioperative period, present an algorithm for mode selection, describe the potential effects of epicardial pacing on valvulopathies and hemodynamics, and, finally, discuss some postoperative considerations.

Effects of solriamfetol treatment on body weight in participants with obstructive sleep apnea or narcolepsy.

Objectives: This analysis characterized changes in weight in participants with obstructive sleep apnea (OSA) or narcolepsy treated with solriamfetol (Sunosi™) 37.5 (OSA only), 75, 150, or 300 mg/d.

Methods: In two 12-week, randomized, placebo-controlled trials and one 1-year open-label extension study, changes in weight were evaluated from baseline to end of study (week 12 or week 40 of the open-label extension [after up to 52 weeks of solriamfetol treatment]) in participants with OSA or narcolepsy.

Best Practice Guidelines for Surgical Site Infection in High-risk Pediatric Spine Surgery: Definition, Prevention, Diagnosis, and Treatment.

Background: Prior "best practice guidelines" (BPG) have identified strategies to reduce the risk of acute deep surgical site infection (SSI), but there still exists large variability in practice. Further, there is still no consensus on which patients are "high risk" for SSI and how SSI should be diagnosed or treated in pediatric spine surgery. We sought to develop an updated, consensus-based BPG informed by available literature and expert opinion on defining high-SSI risk in pediatric spine surgery and on prevention, diagnosis, and treatment of SSI in this high-risk population.

Imaging of eggshells and eggs in the gastrointestinal tract: pictorial essay.

Ingestion of eggshell in its natural form or as ground and powdered product has become a popular means of dietary calcium supplementation in adults. These substances appear as conspicuous radiopaque material within the gastrointestinal tract on radiographs or computed tomography of the abdomen. The ingested eggshell fragments are usually visible as curvilinear structures on profile view, whereas the ground or powdered eggshells appear as granular densities.

Incidence, Mechanisms, Treatment, and Outcomes of Coronary Artery Perforation During Chronic Total Occlusion Percutaneous Coronary Intervention.

Coronary artery perforation is a feared complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Our objective was to describe the incidence, mechanisms, treatment, and outcomes of coronary artery perforation during CTO PCI. We analyzed the baseline clinical and angiographic characteristics and procedural outcomes of 10,454 CTO PCIs performed in 10,219 patients between 2012 and 2022.

Pedicle Screw Plowing in Adolescent Idiopathic Scoliosis: How Common Is It and Is It a Problem?

Study Design: Multicenter retrospective review.

Objective: To calculate overall incidence of pedicle screw "plowing" in adolescent idiopathic scoliosis (AIS) patients who underwent posterior spinal fusion (PSF). To identify risk factors for pedicle screw plowing and associated postoperative outcomes, including loss of correction and revision rate.

High-Dose Osimertinib for CNS Progression in EGFR+ NSCLC: A Multi-Institutional Experience.

Introduction: This multicenter review evaluated the efficacy and safety of osimertinib dose escalation for central nervous system (CNS) progression developing on osimertinib 80 mg in -mutant NSCLC.

Methods: Retrospective review identified 105 patients from eight institutions with advanced -mutant NSCLC treated with osimertinib 160 mg daily between October 2013 and January 2020. Radiographic responses were clinically assessed, and Kaplan-Meier analyses were used.

Single-cell chromatin profiling of the primitive gut tube reveals regulatory dynamics underlying lineage fate decisions.

Development of the gastrointestinal system occurs after gut tube closure, guided by spatial and temporal control of gene expression. However, it remains unclear what forces regulate these spatiotemporal gene expression patterns. Here we perform single-cell chromatin profiling of the primitive gut tube to reveal organ-specific chromatin patterns that reflect the anatomical patterns of distinct organs.

Utility of Cone-Beam CT for Bronchial Artery Embolization and Chemoinfusion: A Single-Institution Retrospective Case Series.

Purpose: To describe the technique and document utility of adjunctive cone-beam CT (CBCT) in patients undergoing bronchial artery embolization (BAE) or chemoinfusion (BAC).

Materials And Methods: Between August 2010 and February 2021, 26 patients (62 bronchial arteries) were evaluated with CBCT in addition to the usual digital subtraction angiography (DSA) during BAE or BAC. 19 patients (43 arteries) underwent BAE for hemoptysis; 7 patients (19 arteries) had BAC for palliation of lung malignancy.

Excess neuropeptides in lung signal through endothelial cells to impair gas exchange.

Although increased neuropeptides are often detected in lungs that exhibit respiratory distress, whether they contribute to the condition is unknown. Here, we show in a mouse model of neuroendocrine cell hyperplasia of infancy, a pediatric disease with increased pulmonary neuroendocrine cells (PNECs), excess PNEC-derived neuropeptides are responsible for pulmonary manifestations including hypoxemia. In mouse postnatal lung, prolonged signaling from elevated neuropeptides such as calcitonin gene-related peptide (CGRP) activate receptors enriched on endothelial cells, leading to reduced cellular junction gene expression, increased endothelium permeability, excess lung fluid, and hypoxemia.
