Fourth Time Redo Common Femoral Vein Reconstruction with a Novel Hybrid Technique.

Background: Iliofemoral vein thrombosis can lead to debilitating edema and venous claudication that significantly worsens quality of life, especially in young active individuals. Venous reconstruction becomes increasingly complex and has worsening patency with subsequent revisions so preoperative planning is critical to success.

Methods: We report a case of a 54-year-old man in active military service with profoundly symptomatic leg swelling after failure of 3 previous common femoral vein (CFV) reconstructions.

Functional Safe Zone Is Superior to the Lewinnek Safe Zone for Total Hip Arthroplasty: Why the Lewinnek Safe Zone Is Not Always Predictive of Stability.

Background: The Lewinnek "safe zone" is not always predictive of stability after total hip arthroplasty (THA). Recent studies have focused on functional hip motion as observed on lateral spine-pelvis-hip x-rays. The purpose of this study was to assess the correlation between the Lewinnek safe zone and the functional safe zone based on hip and pelvic motion in the sagittal plane.

Seventy-nine patients with 80 LPA and 29 patients with 30 sPHEO were included in the study. Texture parameters were derived using imaging software (MaZda).

Catheter-Based Computed Tomography Angiography in Anterolateral Thigh Perforator Mapping of Chinese Patients.

Background:  During reconstructive surgery, anterolateral thigh (ALT) flap harvest is challenging due to variation and uncertainty in perforator distribution. We performed a pilot study to identify the predictive value of catheter-based computed tomography angiography (C-CTA) and traditional CTA (T-CTA) in ALT perforator mapping for patients whose ALT perforators were difficult to identify.

Methods:  Thirty-four consecutive T-CTA/C-CTA-mapped ALT flaps were evaluated for extremity reconstruction.

Reprint of: The pathology of pulmonary sarcoidosis: update.

Sarcoidosis is a multi-system disease of unknown etiology, usually affecting the respiratory tract and other organs, and is characterized by the formation of nonnecrotizing epithelioid granulomas. The diagnosis depends on a combination of a typical clinicoradiological presentation, the finding of nonnecrotizing epithelioid granulomas in a tissue biopsy, and exclusion of other possible diseases, especially those of infectious etiology. The granulomas contain epithelioid cells, giant cells, CD4+ T cells in their center, and CD8+ T lymphocytes and B lymphocytes at their periphery.

The Opioid Crisis and the Orthopedic Surgeon.

Opioid use and abuse has become a national crisis in the United States. Many opioid abusers become addicted through an initial course of legal, physician-prescribed medications. Consequently, there has been increased pressure on medical care providers to be better stewards of these medications.

Novel Therapies for Sleep Apnea-The Implants Have Arrived!

Positive airway pressure (PAP) therapy has been the standard treatment of choice for sleep disordered breathing, with 29-83% of patients being noncompliant. With the advent of newly Food and Drug Adminisatration (FDA)-approved implantable stimulators for treating sleep disordered breathing in a fraction of noncompliant PAP therapy patients, the landscape of sleep medicine and sleep technology is changing to narrow the gap between compliant and non-compliant patients. The remedē® System for treating central sleep apnea and the Inspire® upper airway stimulation (UAS) therapy for treating obstructive sleep apnea are providing new tools for sleep physicians, elevating sleep technologists' expertise, and paving the way for personalized medicine.

Brain Structure Alterations in Respect to Tobacco Consumption and Nicotine Dependence: A Comparative Voxel-Based Morphometry Study.

The main purpose of this study is to examine the lifetime tobacco consumption and the degree of nicotine dependence related gray matter (GM) and white matter (WM) volume alterations in young adult-male smokers. Fifty-three long-term male smokers and 53 well-matched male healthy non-smokers participated in the study, and the smokers were respectively categorized into light and heavy tobacco consumption subgroups by pack-years and into moderate and severe nicotine dependence subgroups using the Fagerström Test for Nicotine Dependence (FTND). Voxel-based morphometry analysis was then performed, and ANCOVA analysis combined with subsequent test were used to explore the between-group brain volume abnormalities related to the smoking amount and nicotine dependence.

Dietary Vitamin E Status Dictates Oxidative Stress Outcomes by Modulating Effects of Fish Oil Supplementation in Alzheimer Disease Model APP/PS1 Mice.

Quite a number of studies have examined the effects of fish oil supplementation on cognitive performance in different transgenic animal models of Alzheimer's disease (AD). However, inconsistent and controversial outcomes have been derived from these experiments. In order to investigate whether the beneficial effect of fish oil supplementation on cognition was dietary VE status associated, fish oil dietary intervention was carried out in transgenic APP/PS1 (APP/PS1) mice.

Vascularized Lymph Node Transfer for Lymphedema.

Advances in our understanding of the lymphatic system and the pathogenesis of lymphedema have resulted in the development of effective surgical treatments. Vascularized lymph node transfer (VLNT) involves the microvascular transplantation of functional lymph nodes into an extremity to restore physiological lymphatic function. It is most commonly performed by transferring combined deep inferior epigastric artery perforator and superficial inguinal lymph node flaps for postmastectomy breast reconstruction.

The Role of ApoE Polymorphism in the Relationship between Serum Steroid Hormone Levels and Cognition in Older Chinese Adults: A Cross-Sectional Study.

Background: Epidemiology studies have indicated an association of apolipoprotein E (ApoE) genetic polymorphism and circulating steroid hormone levels with the risk of Alzheimer's disease. The established physiologic relationship between apolipoproteins and steroid hormone indicate an important role of ApoE polymorphism in impacting the relationship between serum steroid hormones and cognition in the elderly.
