Introduction: Granular cell tumors (GCTs) are of neuroectodermal origin and account for 0.5% of soft tissue tumors. They are most prevalent in African-Americans in the fourth to sixth decades, with a predilection for the head and neck regions. GCTs usually resemble more common lesions and hence are difficult to diagnose preoperatively. The tumor is readily identified on needle biopsy. Although usually benign with a malignancy rate of only 2-3%, the malignant form has a reported 3-yr mortality of 60%...

BACKGROUND: Postoperative complications and length of hospital stay (LOS) are major issues and affect hospital costs. Enhanced Recovery After Surgery (ERAS) protocols are effective in reducing morbidity and LOS after major surgery. We propose a nutritional protocol within ERAS programs in colorectal surgery, starting from preadmission. METHODS: We compared the ERAS + NutriCatt approach versus the ERAS standard program adopted in our center in the previous months...

PURPOSE: Muller's muscle-conjunctival resection (MMCR) is a highly effective technique to correct upper eyelid ptosis. However, several authorities have raised concerns about the possibility of postoperative ocular surface dryness. This study was performed to assess the impact of MMCR on clinically meaningful parameters of the ocular surface. METHODS: In adult patients, tear break-up time, lipid layer thickness, and osmolarity were measured via direct observation, interferometry, and impedance measurements before surgery and 3 months after surgery in patients who underwent MMCR...

Preoperative identification of the eloquent brain is important for neurosurgical planning. One common method of finding the motor cortex is by localizing "the Omega sign." No studies have tested the reliability of imaging to identify the Omega sign. We identified 40 recent and consecutive patients who had undergone preoperative functional magnetic resonance imaging for identification of the hand motor area prior to tumor resection. We recruited 11 neurosurgical residents of various levels of training and one board-certified neurosurgeon to identify the hand motor cortex Omega...

BACKGROUND: Despite advances in perioperative care, post-operative clinical and functional outcomes after major abdominal surgery can be suboptimal. Prehabilitation programmes attempt to optimise a patient's preoperative condition to improve outcomes. Total body prehabilitation includes structured exercise, nutritional optimisation, psychological support and cessation of negative health behaviours. This systematic review aims to report on the current literature regarding the impact of total body prehabilitation prior to major abdominal surgery...

Background: Cognitive decline has been reported following cardiac surgery, leading to great interest in interventions to minimize its occurrence. Long-chain n-3 (ω-3) polyunsaturated fatty acids (PUFAs) have been associated with less cognitive decline in observational studies, yet no trials have tested the effects of n-3 PUFAs on cognitive decline after surgery. Objective: We sought to determine whether perioperative n-3 PUFA supplementation reduces postoperative cognitive decline in patients postcardiac surgery...

Objective: Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival. In this study, we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio (NLR) in predicting the survival of patients with non-small cell lung cancer (NSCLC). Methods: We retrospectively enrolled 589 patients with NSCLC who underwent surgery. The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators, including the combination of fibrinogen and NLR (F-NLR)...

Smoking is associated with increased risk and poorer prognosis of pancreatic ductal adenocarcinoma (PDAC). Nicotine acts through cholinergic nicotinic receptors, preferentially α7 (CHRNA7) that also binds the endogenous ligand SLURP1 (Secreted Ly-6/uPAR-Related Protein 1). The clinical significance of SLURP1 and its interaction with nicotine in PDAC are unclear. We detected similar levels of SLURP1 in sera from healthy donors and patients with chronic pancreatitis or PDAC; higher preoperative values were associated with significantly better survival in patients with resected tumors...

Treatment options for patients with different types of endometriosis - superficial, ovarian, or deep - vary depending on the clinical presentation. New findings in the recent years regarding the role of preoperative imaging, efficacy of medical therapy, and effect of surgery on ovarian reserve have changed the way we understand the disease and subsequently the way we treat our patients. Practicing clinicians frequently refer to published recommendations from major societies for treatment guidelines. This paper aims to present and compare the varying major society guidelines on the indications and best surgical treatment approach for the management of the different types of endometriosis...

BACKGROUND: One-in-five patients are dissatisfied following knee arthroplasty and <50% have fulfilled expectations. The relationship between knee-arthroplasty expectations and surgical outcome remains unclear. PURPOSE: Are expectations regarding the impact of pain on postoperative life predictive of one-year outcome? Does the impact of pain on preoperative quality of life (QOL) influence this relationship? METHODS: Longitudinal cohort of 1044 uni-compartmental (43%) or total knee-arthroplasty (57%) (UKA or TKA) patients, aged mean 69 ± 9 years...

BACKGROUND: Propionibacterium-specific cultures are commonly positive in revised shoulders without obvious signs of infection. To help identify patients at risk for these "stealth" presentations of positive Propionibacterium cultures, we assessed the value of a preoperative skin culture in predicting the results of deep cultures obtained at the time of revision shoulder arthroplasty in patients without clinical evidence of infection. METHODS: The study enrolled 60 patients undergoing revision for a prior shoulder arthroplasty without clinical evidence of infection...

Introduction Esophageal and esophago-gastric junction (EGJ) adenocarcinomas remain a major health problem worldwide with a worryingly increasing incidence. Recent trials indicate survivals benefit for preoperative or perioperative chemoradiotherapy compared to surgery alone. Beside standard chemoradiotherapy regimens, new therapeutic approaches with targeted therapies have been proposed for the treatment of resectable disease. However, clinical outcomes remain extremely poor due to drug resistance phenomena...
