Current Research on Zinc Oxide Nanoparticles: Synthesis, Characterization, and Biomedical Applications.

Zinc oxide nanoparticles (ZnO-NPs) have piqued the curiosity of researchers all over the world due to their extensive biological activity. They are less toxic and biodegradable with the capacity to greatly boost pharmacophore bioactivity. ZnO-NPs are the most extensively used metal oxide nanoparticles in electronic and optoelectronics because of their distinctive optical and chemical properties which can be readily modified by altering the morphology and the wide bandgap.

Simple Prediction Score for Developing Surgical Site Infection after Clean Neck Operation.

Clean neck operations (thyroidectomies, parathyroidectomies, and lymph node resection) are among the most common procedures performed in the United States. Surgical site infections (SSIs) after clean neck operations are rare, but the consequences are devastating and often life-threatening. The aim of this study was to develop a score that will identify patients at high risk for developing a SSI after a clean neck procedure.

Ochratoxins in food and feed: Occurrence and its impact on human health and management strategies.

Ochratoxins (OTs) are a group of mycotoxins produced by Aspergillus and Penicillium spp. which are ubiquitous. They infect the crops during pre- and post-harvest conditions and contaminate various food and feed.

Laparoscopic vs open partial colectomy in elderly patients: Insights from the American College of Surgeons - National Surgical Quality Improvement Program database.

Aim: To compare the outcomes between the laparoscopic and open approaches for partial colectomy in elderly patients aged 65 years and over using the American College of Surgeons - National Surgical Quality Improvement Program (ACS NSQIP) database.

Methods: The ACS NSQIP database for the years 2005-2011 was queried for all patients 65 years and above who underwent partial colectomy. 1:1 propensity score matching using the nearest- neighbor method was performed to ensure both groups had similar pre-operative comorbidities.

Jejunal Intussusception: A Rare Presentation of Carcinoid Tumor.

A 55-year-old male presented to the emergency department with sudden onset of diffuse abdominal pain for one day. Physical examination was remarkable for tenderness in the umbilical region. A CT scan of the abdomen showed intussusception involving the jejunum without any mass.

Medical student perception of night call in a night float system.

Background: Because of work hour regulations, many surgical residency programs have moved to a night float system. Previously, our medical students took call for 24 hours, whereas currently they also follow a night float system. This study looked at their evaluations of these 2 systems.

The use of a surgery-specific written examination in the selection process of surgical residents.

Objective: Selection of surgical residents is a difficult task, and program directors are interested in identifying the best candidates. Among the qualities being sought after is the ability to acquire surgical knowledge, and eventually do well on their board examinations. During the interview process, many programs use results from the United States Medical Licensing Exam (USMLE) to identify residents they think will do well academically.

Intraoperative breast problem--focused sonography a valuable tool in the training of surgical residents.

Introduction: In surgical residency education, "hands-on" learning is important in the operating room. Mastering the interpretation of preoperative data is a must for intraoperative decisions. Because preoperative evaluations of breast masses by ultrasound are performed and interpreted in the Department of Radiology, our study aimed to assess and improve surgical residents' ability to perform ultrasound and to interpret their results before performing breast mass biopsies.

Electronic submission of resident work hours: a convenient way of exchange of information.

The purpose of this protocol is to assess how residents can document their work hours in a convenient and objective way; to find an efficient, secure, quick, and reproducible way of communication between house staff and residency administrators regarding work hours data; and to fulfill the requirements of the Accreditation Council for Graduate Medical Education and other monitoring bodies regarding work hours documentation. This electronic work hours submission protocol is based on the Microsoft Excel system. The data is submitted via e-mail to the residency coordinators.

Abdominal wall endometriomas.

Background: The diagnosis of abdominal wall endometriomas is often confused with other surgical conditions.

Methods: A retrospective study was made of 12 patients presenting with an abdominal wall mass, which proved to be endometrioma.

Results: Of a total of 297 patients of endometriosis treated in our hospital over a 7-year period, 12 (4%) had isolated abdominal wall endometriomas.

Cystic Hypersecretory Duct Carcinoma of the Breast.

We present two cases of a rare form of intraductal carcinoma of the breast, "cystic hypersecretory carcinoma of the breast." The clinical and pathologic characteristics of the lesion are discussed, along with a review of the literature.
