Authors: Abu Arab Walid Salah , Elhamami Moustafa Mohamed 
Published: February 2021

Introduction Primary palmar hyperhidrosis is an abnormal over-sweating of palms. It is usually associated with plantar hyperhidrosis. Video-assisted thoracoscopic sympathectomy is the treatment of choice for palmar hyperhidrosis; however, it may affect plantar hyperhidrosis. Objectives The aim of this study was to evaluate the effect of thoracoscopic sympathectomy on plantar hyperhidrosis. Methods This prospective study included patients who presented to the Cardiothoracic Surgery Department with primary palmo-planter hyperhidrosis and received thoracoscopic sympathectomy between January 2014 and December 2018. Preoperatively, patients scored subjectively the degree of palmar and plantar hyperhidrosis on Visual Analogue Scale. Following surgery, scoring was performed at three intervals: 7, 30, and 180 days. Presence of compensatory sweating and its scoring was obtained at the same intervals. Complications and patient satisfaction were recorded. Results A total of 518 patients were included. Complication rate, excluding compensatory hyperhidrosis, was 2.7%. Preoperative Visual Analogue Scale score for palmar hyperhidrosis was 9.9 ± 3.8 that following thoracoscopic sympathectomy decreased to 0.041 ± 0.2 on the seventh postoperative day. Further decrease to 0.3 ± 0.16 was noted on the 30th day and 180th day postoperatively. Preoperative Visual Analogue Scale score for plantar hyperhidrosis was 9.54 ± 0.66 that following sympathectomy decreased to 2.27 ± 1.67 on the seventh postoperative day. However, slight insignificant increase was noted to become 2.73 ± 1.65 on the 30th day and 6th month postoperatively. Compensatory hyperhidrosis was recorded in 3.9% of patients at 6th month postoperatively. Conclusion Palmar hyperhidrosis is usually associated with plantar hyperhidrosis. Thoracoscopic sympathectomy is an effective and safe treatment for palmar hyperhidrosis. It may completely or partially cure plantar hyperhidrosis.

Background Congenital heart disease (CHD) is the most common neonatal and pediatric cardiac indication for extracorporeal membrane oxygenation (ECMO). Risk factors of survival and neurologic complication were different in many centers. We sought to evaluate survival and neurological outcome after ECMO in patients with CHD. Methods We retrospectively reviewed the medical records of 37 patients (<16 years old) who received ECMO. Indications for ECMO were failure to wean from cardiopulmonary bypass in 18 patients, extracorporeal cardiopulmonary resuscitation (ECPR) in 13 patients, and others in 6 patients. The median cardiopulmonary resuscitation (CPR) duration in ECPR patients was 48 min (interquartile range: 38–53 min). Neurological outcomes were evaluated using the Pediatric Cerebral Performance Category (PCPC) scale one year after hospital discharge. Results The median ECMO duration was 160 (91–286) h. Twenty-nine patients (78%) were successfully weaned off ECMO. Overall survival to hospital discharge was 59%. Risk factors of mortality were as follows: ECMO duration >1 week and urine output <1 mL/kg/h in the first 24 h after ECMO induction by multivariable analysis. Of the 22 survivors, 15 (68%) patients had a favorable outcome (PCPC ≤2). Risk factors for unfavorable outcomes (PCPC ≥3) included ECPR as indication and CPR of longer than 40 min. Conclusions Longer ECMO duration and lower urine output were associated with increased mortality. Neurologic outcomes were not satisfactory when CPR was required for a longer period before ECMO establishment.

Objective This prospective, dose-escalation phase I study evaluated the safety and efficacy of intraperitoneal bevacizumab in managing refractory malignant ascites and explored the recommended dose of bevacizumab for further study. Methods Patients with refractory malignant ascites were enrolled. Bevacizumab was intraperitoneal administered weekly at an initial dose of 2.5 mg/kg, with dose escalation to 5 and 7.5 mg/kg performed following the standard “3 + 3” rule. The total duration of treatment was 2 or 3 weeks. Results Between December 2013 and September 2014, 13 patients (2.5 mg/kg, n = 4; 5 mg/kg, n = 3; 7.5 mg/kg, n = 6) with refractory malignant ascites were enrolled. Bevacizumab was well tolerated, and the most common treatment-related adverse events were abdominal pain (5/13), abdominal distension (2/13), and fatigue (2/13). The dose-limiting toxicity at 7.5 mg/kg was grade 3 bowel obstruction (1/13). The maximum tolerated dose (MTD) was not reached. The overall response and disease control rates were 7.7 and 61.5%, respectively. Conclusions Intraperitoneal bevacizumab safe and well tolerated for treating malignant ascites, and the MTD was not reached at doses of 2.5 to 7.5 mg/kg. Intraperitoneal bevacizumab at 7.5 mg/kg weekly is recommended for further study to verify its anti-tumor activity. Trial registration: Clinical Trials NCT01852409.
Two hundred and forty-eight cases of visual snow: A review of potential inciting events and contributing comorbidities
Authors: Mehta Dev G , Garza Ivan , Robertson Carrie E 
Published: February 2021

Objective To review characteristics and outcomes of all cases of visual snow seen at our institution, with attention to possible triggering events or comorbidities. Methods This is a retrospective case series of patients seen at our tertiary care center from January 1994 to January 2020. Charts were reviewed if they contained the term “visual snow”. Results Of the 449 charts reviewed, 248 patients described seeing visual snow in part or all of their vision. Thirty-eight reported transient visual snow as their typical migraine aura. Of the remaining 210 patients, 89 were reported to have either an inciting event or contributing comorbidity for their visual snow symptoms, including: Post-concussion (n = 15), dramatic change in migraine or aura (n = 14), post-infection (n = 13), hallucinogen persisting perception disorder (n = 10), ocular abnormalities (n = 7), idiopathic intracranial hypertension (n = 4), neoplastic (n = 1), and posterior cortical atrophy (n = 1). Some patients had partial improvement with benzodiazepines (n = 6), lamotrigine (n = 5), topiramate (n = 3) and acetazolamide (n = 3). Presenting characteristics were similar, but patients with visual snow attributed to an inciting event or contributing comorbidity were more likely to have some improvement in their symptoms by last follow-up compared to spontaneous visual snow ( p < .001). Conclusions Though most cases of visual snow are spontaneous, potential secondary causes should be recognized by clinicians. Patients who develop visual snow after an inciting event or related to an underlying comorbidity may have a better prognosis than those in whom it develops spontaneously. In select cases, treatment of the suspected underlying cause may significantly alleviate the otherwise typical intractable visual disturbances associated with visual snow.

Background: Loading interventions have become a predominant treatment strategy for tendinopathy, and positive clinical outcomes and tendon tissue responses may depend on the exercise dose and load magnitude. Purpose/Hypothesis: The purpose was to investigate if the load magnitude influenced the effect of a 12-week loading intervention for patellar tendinopathy in the short term (12 weeks) and long term (52 weeks). We hypothesized that a greater load magnitude of 90% of 1 repetition maximum (RM) would yield a more positive clinical outcome, tendon structure, and tendon function compared with a lower load magnitude of 55% of 1 RM when the total exercise volume was kept equal in both groups. Study Design: Randomized clinical trial; Level of evidence, 1. Methods: A total of 44 adult participants with chronic patellar tendinopathy were included and randomized to undergo moderate slow resistance (MSR group; 55% of 1 RM) or heavy slow resistance (HSR group; 90% of 1 RM). Function and symptoms (Victorian Institute of Sport Assessment–Patella questionnaire [VISA-P]), tendon pain during activity (numeric rating scale [NRS]), and ultrasound findings (tendon vascularization and swelling) were assessed before the intervention, at 6 and 12 weeks during the intervention, and at 52 weeks from baseline. Tendon function (functional tests) and tendon structure (ultrasound and magnetic resonance imaging) were investigated before and after the intervention period. Results: The HSR and MSR interventions both yielded significant clinical improvements in the VISA-P score (mean ± SEM) (HSR: 0 weeks, 58.8 ± 4.3; 12 weeks, 70.5 ± 4.4; 52 weeks, 79.7 ± 4.6) (MSR: 0 weeks, 59.9 ± 2.5; 12 weeks, 72.5 ± 2.9; 52 weeks, 82.6 ± 2.5), NRS score for running, NRS score for squats, NRS score for preferred sport, single-leg decline squat, and patient satisfaction after 12 weeks, and these were maintained after 52 weeks. HSR loading was not superior to MSR loading for any of the measured clinical outcomes. Similarly, there were no differences in functional (strength and jumping ability) or structural (tendon thickness, power Doppler area, and cross-sectional area) improvements between the groups undergoing HSR and MSR loading. Conclusion: There was no superior effect of exercising with a high load magnitude (HSR) compared with a moderate load magnitude (MSR) for the clinical outcome, tendon structure, or tendon function in the treatment of patellar tendinopathy in the short term. Both HSR and MSR showed equally good, continued improvements in outcomes in the long term but did not reach normal values for healthy tendons.

Published: February 2021

Background: Incompetence of the anterior cruciate ligament (ACL) confers knee laxity in the sagittal and axial planes that is measurable with clinical examination and diagnostic imaging. Hypothesis: An ACL-deficient knee will produce a more vertical orientation of the lateral collateral ligament (LCL), allowing for the entire length of the LCL to be visualized on a single coronal slice (coronal LCL sign) on magnetic resonance imaging. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Charts were retrospectively reviewed from April 2009 to December 2017 for all patients treated with ACL reconstruction (constituting the ACL-deficient cohort). A control cohort was separately identified consisting of patients with a normal ACL and no pathology involving the collateral ligaments or posterior cruciate ligament. Patients were excluded for follow-up <2 years, incomplete imaging, and age >19 years. Tibial translation and femorotibial rotation were measured on magnetic resonance images, and posterior tibial slope was measured on a lateral radiograph of the knee. Imaging was reviewed for the presence of the coronal LCL sign. Results: The 153 patients included in the ACL-deficient cohort had significantly greater displacement than the 70 control patients regarding anterior translation (5.8 vs 0.3 mm, respectively; P < .001) and internal rotation (5.2° vs −2.4°, P < .001). Posterior tibial slope was not significantly different. The coronal LCL sign was present in a greater percentage of ACL-deficient knees than intact ACL controls (68.6% vs 18.6%, P < .001). The presence of the coronal LCL sign was associated with greater anterior tibial translation (7.2 vs 0.2 mm, P < .001) and internal tibial rotation (7.5° vs –2.4°, P = .074) but not posterior tibial slope (7.9° vs 7.9°, P = .973) as compared with its absence. Multivariate analysis revealed that the coronal LCL sign was significantly associated with an ACL tear (odds ratio, 12.8; P < .001). Conclusion: Our study provides further evidence that there is significantly more anterior translation and internal rotation of the tibia in the ACL-deficient knee and proves our hypothesis that the coronal LCL sign correlates with the presence of an ACL tear. This coronal LCL sign may be of utility for identifying ACL tears and anticipating the extent of axial and sagittal deformity.

Published: February 2021

Introduction To describe pharmacist interventions as a result of an independent double check during cognitive order verification of outpatient parenteral anti-cancer therapy. Methods A single-center, retrospective analysis of all individual orders for outpatient, parenteral anti-cancer agents within a hematology/oncology infusion center during a 30 day period was conducted. The primary endpoint was error identification rates during first and second verification. Secondary endpoints included the type, frequency, and severity of errors identified during second verification using a modified National Coordinating Council for Medication Error Reporting and Prevention Index. Results A total of 1970 anti-cancer parenteral orders were screened, from which 1645 received an independent double check and were included. The number of errors identified during first and second verification were 30 (1.8%) and 10 (0.6%) respectively; second verification resulted in a 33.3% increase in corrected errors. The 10 errors identified during second verification included: four rate transcriptions to optimize pump interoperability, three rate and/or volume modifications, two dosage adjustments, and one treatment deferral due to toxicity. The severity was classified as Category A for four (40%), Category C for three (30%), and Category D for three (30%) errors. This correlated to a low capacity for harm for seven (70%) and a serious capacity for three (30%) errors. Conclusions Second verification of outpatient, parenteral anti-cancer medication orders resulted in a 33.3% increase in corrected errors. Three errors detected during second verification were determined to have a serious capacity for harm, supporting the value of independent double checks during pharmacist cognitive order verification.

Objective: It is unclear whether monocyte/macrophage insulin signaling in humans is affected by type 2 diabetes (T2DM), systemic insulin sensitivity, and other unknown factors. Research design and methods: Fifty-three adult volunteers (control group) not taking any medication and without cardiovascular risk factors, and 59 patients with T2DM (T2DM group) were included. Monocytes were isolated and cultured from all participants. Results: In cultured monocytes, insulin-stimulated AKT and FOXO3 phosphorylation was significantly suppressed in T2DM compared with that in the control group. Insulin-stimulated phosphorylation of AKT was significantly correlated with body mass index and serum insulin level only in the control group. In both groups, significant negative correlation between age and insulin-stimulated phosphorylation of AKT and FOXO3 was commonly observed. In the control group, lipopolysaccharide (LPS)-stimulated induction of TNFA, and NOS2 was significantly and negatively correlated with insulin-stimulated AKT phosphorylation. Age was also significantly correlated with LPS-stimulated induction of TNFA. Discussion: Aging plays an important role in the development of monocyte insulin resistance, not only in patients with T2DM but also in healthy participants. Monocyte insulin sensitivity is negatively correlated with inflammatory responses and may be helpful for subclinical risk assessment of CVDs and/or insulin resistance in participants without risk factors.
Utility of manual fractional anisotropy measurements in the management of patients with Parkinson disease: a feasibility study with a 1.5-T magnetic resonance imaging system
Authors: de Oliveira Romulo V , Pereira João S 
Published: February 2021

Background Diffusion tensor imaging has emerged as a promising tool for quantitative analysis of neuronal damage in Parkinson disease, with potential value for diagnostic and prognostic evaluation. Purpose The aim of this study was to examine Parkinson disease-associated alterations in specific brain regions revealed by diffusion tensor imaging and how such alterations correlate with clinical variables. Material and Methods Diffusion tensor imaging was performed on 42 Parkinson disease patients and 20 healthy controls with a 1.5-T scanner. Manual fractional anisotropy measurements were performed for the ventral, intermediate, and dorsal portions of the substantia nigra, as well as for the cerebral peduncles, putamen, thalamus, and supplementary motor area. The correlation analysis between these measurements and the clinical variables was performed using χ2 variance and multiple linear regression. Results Compared to healthy controls, Parkinson disease patients had significantly reduced fractional anisotropy values in the substantia nigra ( P < .05). Some fractional anisotropy measurements in the substantia nigra correlated inversely with duration of Parkinson disease and Parkinson disease severity scores. Reduced fractional anisotropy values in the substantia nigra were also correlated inversely with age variable. fractional anisotropy values obtained for the right and left putamen varied significantly between males and females in both groups. Conclusion Manual fractional anisotropy measurements in the substantia nigra were confirmed to be feasible with a 1.5-T scanner. Diffusion tensor imaging data can be used as a reliable biomarker of Parkinson disease that can be used to support diagnosis, prognosis, and progression/treatment monitoring.

Published: February 2021

Background Technology for concussion identification and management is rapidly expanding across the continuum of care. Although many technologies offer a range of services around concussion, there is an absence of a non-commercial online location for medical providers to access regarding the functionality of the various technologies used in concussion identification and management. Objective The purpose of this review is to present research findings on technology for concussion identification and management. Methods Searches for eligible studies were conducted using the PubMed, EMBASE, and Scopus databases with specific search criteria. Through a stepwise process, full-text articles were selected for inclusion if they described clinically useful electronic technologies (i.e. electronics able to be used in standard clinical environments including telehealth) by healthcare providers or end users (i.e. parents or athletes). Results A total of 29 articles were included in this review and described technology used to measure symptoms (3), neurocognitive performance (7), the visual system (4), and balance or dual task performance (18). Within the results, various technologies demonstrated increased utility for concussion identification, often detecting subtle deficits not possible with current low-tech clinical methods, differentiating those with concussion from those without concussion, with strong reliability and validity. Conclusion Innovative technologies included in this review demonstrate enhanced ability to identify and manage symptoms of concussion, neurocognitive deficits, visual deficits, and balance and dual-task deficits.

Published: February 2021

Introduction: This study sought to investigate whether a validated trauma triage tool can stratify hospital quality measures and inpatient cost for middle-aged and geriatric trauma patients with isolated proximal and midshaft humerus fractures. Materials and Methods: Patients aged 55 and older who sustained a proximal or midshaft humerus fracture and required inpatient treatment were included. Patient demographic, comorbidity, and injury severity information was used to calculate each patient’s Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA). Based on scores, patients were stratified to create minimal, low, moderate, and high risk groups. Outcomes included length of stay, complications, operative management, ICU/SDU-level care, discharge disposition, unplanned readmission, and index admission costs. Results: Seventy-four patients with 74 humerus fractures met final inclusion criteria. Fifty-eight (78.4%) patients presented with proximal humerus and 16 (21.6%) with midshaft humerus fractures. Mean length of stay was 5.5 ± 3.4 days with a significant difference among risk groups (P = 0.029). Lower risk patients were more likely to undergo surgical management (P = 0.015) while higher risk patients required more ICU/SDU-level care (P < 0.001). Twenty-six (70.3%) minimal risk patients were discharged home compared to zero high risk patients (P = 0.001). Higher risk patients experienced higher total inpatient costs across operative and nonoperative treatment groups. Conclusion: The STTGMA tool is able to reliably predict hospital quality measures and cost outcomes that may allow hospitals and providers to improve value-based care and clinical decision-making for patients presenting with proximal and midshaft humerus fractures. Level of Evidence: Prognostic Level III.
