Human visual cortex does not represent the whole visual field with the same detail. Changes in receptive field size, population receptive field (pRF) size and cortical magnification factor (CMF) with eccentricity are well established, and associated with changes in visual acuity with eccentricity. Visual acuity also changes across polar angle. However, it remains unclear how RF size, pRF size and CMF change across polar angle. Here, we examine differences in pRF size and CMF across polar angle in V1, V2 and V3 using pRF modeling of human fMRI data...

PURPOSE: To guide early stage breast cancer patients to choose between breast conserving surgery (BCS) and mastectomy (MST) considering the predicted cosmetic result and quality of life (QoL). METHODS: A decision model was built to compare QoL after BCS and MST. Treatment could result in BCS with good cosmesis, BCS with poor cosmesis, MST only, and MST with breast reconstruction. QoL for these treatment outcomes were obtained from a previous study and the literature and translated into EuroQoL-5D derived utilities...

Nonalcoholic fatty liver disease (NAFLD) defines a condition of hepatic steatosis with or without hepatic injury. NAFLD is increasing in prevalence worldwide and presents a public health burden. Most patients are asymptomatic, although some present with fatigue and right upper quadrant pain. NAFLD is discovered incidentally when patients have elevated liver enzymes or fatty liver is seen on imaging modalities. Imaging studies can confirm fatty deposits in the liver, but needle biopsy is needed to determine degree of inflammation...

The prevalence of gallstones is 10% to 15% in adults. Individuals with acute cholecystitis present with right upper quadrant pain, fever, and leukocytosis. Management includes supportive care and cholecystectomy. The prevalence of choledocholithiasis is 10% to 20%, and serious complications include cholangitis and gallstone pancreatitis. The goal of management in individuals with choledocholithiasis consists of clearing common bile duct stones. Acute ascending cholangitis is a life-threatening condition involving acute inflammation and infection of the common bile duct...

The angulation of equine incisors is frequently used as a parameter for dental corrections. However, the term incisor angle is only vaguely defined, and no studies exist presenting a series of reliable measurements in individual incisors of multiple horses. The aim of this study was to establish an exact method to determine incisor angles and to test whether clinically accessible landmarks (facial crest and bars) are suitable to estimate incisor angles. Eighteen horses were used to create 3-dimensional (3D) reconstructions of the skulls from computed tomography (CT) data sets...

Tuberous sclerosis complex (TSC) 1 or TSC2 is mutated in most TSC patients. TSC2 mutations are more frequently associated with worse outcomes, earlier age at seizure onset, more severe intellectual disability, and higher tuber load than TSC1. The degree of white matter involvement is thought to be associated with the severity of neurological impairment. At present, genotype-phenotype correlations and relationship between tuber burden and neurological disability in TSC are debatable. We presented a 43-year-old patient with TSC2 mutation, whose symptom was only incomplete quadrantic visual field deficit in spite of multiple brain tubers...

INTRODUCTION: Phyllodes tumors (PTs) of the breast are extremely rare accounting for less than 1% of all breast tumors globally. Case records at the Trinidad and Tobago Cancer Registry show that only 0.003% of the reported breast cancer cases between 1995 and 2009 were PTs. PRESENTATION OF THE CASE: We report a 45-year-old woman who presented with swelling of the left breast. Ultrasound, mammogram and computed tomography imaging confirmed the presence of a mass in the right upper inner quadrant of the left breast...

BACKGROUND: Hemangiomas are common cutaneous findings on healthy infants. These vascular malformations are generally benign, though in rare circumstances they can potentially be fatal. This is particularly true when the hemangiomas are large or numerous and occurring in visceral organs. Previously unrecognized visceral hemangiomas are part of the differential for any neonate presenting unexpectedly in shock.

INTRODUCTION: Pancreatic neuroendocrine tumors are rare. Treatment includes aggressive local management of the primary lesion and metastases, and systemic somatostatin. This is the first report of an isolated metachronous metastasis to the adrenal gland from a pancreatic neuroendocrine tumor that presented 90 months after the primary tumor. PRESENTATION OF CASE: The patient presented as a 53yo man with a left upper quadrant mass and synchronous metastases to the spleen and liver (pancreatic neuroendocrine tumor T4N0M1, Stage IV), which were resected (CD56-, synaptophysin+, chromogranin+, Ki-67<1%)...

Only two cases of myofibroblastic sarcoma in the liver have been reported in the literature. Here, we report the case of a male patient with high-grade myofibroblastic sarcoma mimicking echinococcosis in the liver. The 25-year-old male patient complained of right upper quadrant swelling pain for one week and was initially diagnosed with echinococcosis. He was then scheduled for an exploratory laparotomy. During the operation, a huge mass exceeding 16 cm in diameter was found to occupy nearly the entire right trisegment of the liver, with a clear boundary and a round shape, and the mass was resected by right hepatic trisegmentectomy...

A 54-year-old man presented with severe right upper quadrant (RUQ) abdominal pain. He denied any infective symptoms. On clinical examination, he was afebrile and anicteric. His abdomen was soft with tenderness elicited on the RUQ. A point-of-care ultrasound in the emergency department demonstrated a distended gallbladder with a thickened wall and an impacted large gallstone at the neck of the gallbladder. Furthermore, the point-of-care ultrasound also identified a highly reflective echo from the anterior surface of the gallstone and marked posterior acoustic shadowing...

A spontaneous external biliary fistula is most commonly a cholecystocutaneous fistula secondary to acute cholecystitis. A fistula arising from an intrahepatic duct is extremely rare. An 87-year-old man presented with swelling of the epigastric region and right upper quadrant abdomen. He had a history of cholecystectomy and endoscopic sphincterotomy. After antibiotic treatment and surgical opening of both lesions, abdominal computed tomography demonstrated a soft tissue mass cephalad to the umbilicus. We excised the mass, and found it to be associated with a fistula through the linea alba...

Situs inversus totalis is the mirror image of situs solitus, the normal position of abdominal and thoracic viscera. Many associated intraabdominal anomalies have been described with this condition. However, association of choledochal cyst with situs inversus has never been reported. Diagnosis and surgical procedures for abdominal pathology in patients with situs inversus totalis are technically more complicated and pose unique challenges because of left-right transposition of the visceral organs. The choledochal cyst is usually diagnosed in the neonatal period or during childhood...

Background: Oncoplastic surgery is increasingly performed in Korean women; however, unlike Westerners, Korean women usually have small- to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors determining the optimal surgical method should be considered. Methods: A total of 108 patients who underwent oncoplastic surgery from January 2013 to December 2016 were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD) flap transposition, and reduction oncoplasty to restore the breast volume and symmetry...

Purpose: Alterations in retinal oxygen metabolism and retinal microcirculation are signs of impending diabetic retinopathy (DR). However, if specific retinal regions are primarily affected is so far unknown. The purpose of this study was to investigate if retinal oxygen saturation (SO2) and microvascular hemodynamic parameters follow a distinct regional pattern in patients with diabetes but no DR. Methods: Patients with type II diabetes without clinically apparent DR were imaged as follows: SO2 in peripapillary vessels was assessed with dual-wavelength oximetry...

BACKGROUND: Reduced port laparoscopic surgery (RPLS), as a more minimally invasive treatment alternative to conventional laparoscopic surgery (CLS), has been increasing in recent years. (1) With the accumulation of surgical experience and improvements in surgical techniques, the indication of RPLS has been gradually extended from benign diseases to malignant tumors, including gastric cancer. (2-4) However, due to the lack of counteraction and triangulation, lymphadenectomy during reduced port laparoscopic gastrectomy (RPLG) for gastric cancer was considered challenging...
