INTRODUCTION: The goal of this study was to integrate temporal and weather data in order to create an artificial neural network (ANN) to predict trauma volume, the number of emergent operative cases, and average daily acuity at a level 1 trauma center. METHODS: Trauma admission data from TRACS and weather data from the National Oceanic and Atmospheric Administration (NOAA) was collected for all adult trauma patients from July 2013-June 2016. The ANN was constructed using temporal (time, day of week), and weather factors (daily high, active precipitation) to predict four points of daily trauma activity: number of traumas, number of penetrating traumas, average ISS, and number of immediate OR cases per day...

Peroral endoscopic myotomy (POEM) for treatment of esophageal motility disorders has recently been reported to be highly effective and less invasive than other treatment. POEM was recently introduced in Okayama University Hospital under the supervision of a physician from a high-volume center. To verify the safety and efficacy of POEM during its introduction in our institution. We examined 10 cases in whom POEM was performed between January 2016 and April 2017. The patients included 7 men and 3 women, with a median age (range) of 49 years (17-74) and median symptom duration of 6 years (1-21)...

BACKGROUND Sigmoid volvulus (SV) is a life-threatening condition occasionally seen in adults. Adult Hirschsprung's disease (HD)-related SV is rarely complicated by difficult-to-control hypertension. In this report we present the case of an elderly man with a rare constellation of HD, SV, and refractory hypertension. CASE REPORT An 82-year-old man had long-term constipation, moderate abdominal pain, and progressive abdominal distension. A CT scan revealed the typical "coffee bean sign". Blood pressure was abnormal high...

BACKGROUND: Somapacitan, a long-acting growth hormone (GH) derivative, has been well-tolerated in children with GH deficiency (GHD) and adults (healthy and adult GHD), in phase I, single- and multiple-dose trials, respectively, and has pharmacokinetic and pharmacodynamic properties supporting a once-weekly dosing regimen. OBJECTIVE: In the absence of a multiple-dose phase I trial in children with GHD, the aim was to develop a pharmacokinetic/pharmacodynamic model to predict somapacitan exposure and insulin-like growth factor-I (IGF-I) response after once-weekly multiple doses in both children and adults with GHD...

Artificial neural networks can harness stochasticity in multiple ways to enable a vast class of computationally powerful models. Boltzmann machines and other stochastic neural networks have been shown to outperform their deterministic counterparts by allowing dynamical systems to escape local energy minima. Electronic implementation of such stochastic networks is currently limited to addition of algorithmic noise to digital machines which is inherently inefficient; albeit recent efforts to harness physical noise in devices for stochasticity have shown promise...

Pretomanid is a nitroimidazole antibiotic in late phase clinical testing as a component of several novel antituberculosis (anti-TB) regimens. A population pharmacokinetic model for pretomanid was constructed using a Bayesian analysis of data from two phase 2 studies, PA-824-CL-007 and PA-824-CL-010, conducted with newly diagnosed adult (median age 27 years) pulmonary TB patients in Cape Town, South Africa. Combined, these studies included 63 males and 59 females administered once daily oral pretomanid doses of 50, 100, 150, 200, 600, 1000, or 1200 mg for 14 days...

BACKGROUND Appendicitis is the most common cause of abdominal pain requiring emergent surgical intervention. Although typically presenting as right lower-quadrant pain, in rare cases it may present as left upper-quadrant pain secondary to abnormal position due to intestinal malrotation. Since atypical presentations may result in diagnostic and management delay, increasing morbidity and mortality, accurate and prompt diagnosis is important. Therefore, acute appendicitis should be considered in the differential diagnosis of left upper-quadrant abdominal pain...

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a new clinical entity that was reclassified from enteropathy-associated T-cell lymphoma in the 2016 WHO classification. An 83-year-old man with fever and diarrhea was referred to our hospital because of free air in the abdominal cavity and wall thickening of the large intestine on CT. Colonofiberscopic examination revealed mucosal edema and multiple ulcers at the sigmoid colon, splenic flexure, and transverse colon. Histopathological examination of the mucosal biopsy specimen demonstrated dense infiltration of small lymphocytes with nuclear atypia, some of which exhibited intraepithelial invasion...

Abdominal symptoms are common in patients with lupus nephritis and are often attributed to drugs or uremia per se. Lupus mesenteric vasculitis (LMV) or lupus enteritis is a rare entity reported in patients with active systemic lupus erythematosus. It usually occurs in patients with a long-standing history of lupus with high disease activity. Usually, small bowel is predominantly affected. The stomach and rectum are spared in view of significant collateral circulation. Here, we describe an 18-year-old boy who presented with nephrotic syndrome without any extrarenal features of lupus...

BACKGROUND: Recovery after colonic surgery is invariably delayed by disturbed gut motility. It is commonly assumed that colonic motility becomes quiescent after surgery, but this hypothesis has not been evaluated rigorously. This study quantified colonic motility through the early postoperative period using high-resolution colonic manometry. METHODS: Fibre-optic colonic manometry was performed continuously before, during and after surgery in the left colon and rectum of patients undergoing right hemicolectomy, and in healthy controls...

We report a case of chemotherapy with FOLFOXIRI plus cetuximab for liver metastasis of sigmoid colon cancer. The patient was a 40's man who was diagnosed with sigmoid colon cancer with liver metastasis. Colonoscopy revealed a type 2 tumor with stenosis in the sigmoid colon. He underwent sigmoidectomy under laparotomy, and after the operation, received 7 courses of chemotherapy with FOLFOXIRI plus cetuximab. The liver tumor was sufficiently reduced, and laparotomy and liver right lobectomy were performed. Histopathology revealed a modified, Grade 2 tumor regression...

An 80-year-old man reported at our hospital with the chiefcomplaint ofconstipation. He was diagnosed with sigmoid colon cancer(T4aN0M0, Stage II). He also had steroid-resistant idiopathic thrombocytopenic purpura(ITP)since 2001. After a high dose g-globulin therapy, he underwent sigmoidectomy and splenectomy simultaneously because ofthe steroidresistant ITP. While some reports suggest that ITP is dominant when it occurs with blood cancer, others suggest that it can be immunologically dominant even when it occurs with solid tumors...
