Mammary analogue secretory carcinoma involving submandibular gland: Diagnostic pitfall with review of literature.

Mammary analogue secretory carcinoma (MASC) is a recently defined entity among salivary gland tumors. MASC bores a striking resemblance to secretory carcinoma of breast along with the characteristics of ETV6-NTRK3 translocation. Hence, the entity was designated as MASC and was formally included in the 4th edition of World Health Organization classification of head and neck tumors in 2017.

Intraorbital Foreign Body- Endoscope Assisted Removal.

Intraorbital wooden foreign body is uncommon in patients with orbital trauma, and if present its complete surgical removal at the earliest is of utmost importance to avoid significant complications. We report an interesting case of an intraorbital wooden foreign body that was succesfully removed using a nasal endoscope.

Patterned thin film enzyme electrodes spincoating and glutaraldehyde vapor crosslinking: towards scalable fabrication of integrated sensor-on-CMOS devices.

Effective continuous glucose monitoring solutions require consistent sensor performance over the lifetime of the device, a manageable variance between devices, and the capability of high volume, low cost production. Here we present a novel and microfabrication-compatible method of depositing and stabilizing enzyme layers on top of planar electrodes that can aid in the mass production of sensors while also improving their consistency. This work is focused on the fragile biorecognition layer as that has been a critical difficulty in the development of microfabricated sensors.

The Impact of Surgical Timing After Ankle Fracture on Clinical and Long-Term Patient Reported Outcomes.

The goal of this study is to evaluate the effect of time-to-surgery following closed ankle fractures on long-term patient reported outcomes, fracture healing, and wound complications. To date, little research has been done focusing on the impact "time to definitive fixation" has on patient reported outcomes. We performed a retrospective analysis of 215 patient records who underwent open reduction and internal fixation (ORIF) for an ankle fracture from July 2011 to July 2018.

Complication Rates Are Similar Between Patients Aged <50 and >50 Years in Calcaneus Fractures Treated With the Sinus Tarsi Approach.

Background: The sinus tarsi (ST) approach for calcaneus fractures has gained popularity in recent years with an increased interest in shifting to less invasive approaches for calcaneal fracture fixation allowing for adequate fixation if complications do not arise. Although the ST approach has gained acceptance as standard for calcaneus fracture fixation, the literature surrounding early complications rates based on age differences for this specific approach and pathology is lacking. The objective of this study was to determine if rates of complications based on age varied for patients undergoing open reduction and internal fixation (ORIF) of closed calcaneus fractures using the ST approach.

Systemic Toxicity of Smokeless Tobacco Products in Mice.

Introduction: Smokeless tobacco products such as snuff and snus are used worldwide. However, little is known about the systemic and cardiovascular toxicity of smokeless tobacco exposure.

Methods: Biomarkers of endothelial activation and injury, immune functions, platelet activation and insulin resistance were measured in 8-week old male C57BL/6 mice exposed to commercial snuff, CRP-2 reference snuff, commercial snus, CRP-1 reference snus, and nicotine in drinking water (100 µg/mL) for 4, 12, and 24 weeks.

Biomarkers of Chronic Acrolein Inhalation Exposure in Mice: Implications for Tobacco Product-Induced Toxicity.

Exposure to tobacco smoke, which contains several harmful and potentially harmful constituents such as acrolein increases cardiovascular disease (CVD) risk. Although high acrolein levels induce pervasive cardiovascular injury, the effects of low-level exposure remain unknown and sensitive biomarkers of acrolein toxicity have not been identified. Identification of such biomarkers is essential to assess the toxicity of acrolein present at low levels in the ambient air or in new tobacco products such as e-cigarettes.

Atherogenesis and metabolic dysregulation in LDL receptor-knockout rats.

Mechanisms of atherogenesis have been studied extensively in genetically engineered mice with disturbed cholesterol metabolism such as those lacking either the LDL receptor (Ldlr) or apolipoprotein E (apoe). Few other animal models of atherosclerosis are available. WT rabbits or rats, even on high-fat or high-cholesterol diets, develop sparse atherosclerotic lesions.
