INTRODUCTION: Rapunzel syndrome is a rare intestinal condition that starts with the ingestion of a trichobezoar. The condition is predominately found in females and can be associated with trichotillomania, or the compulsive urge to pull one's own hair out. There are less than 40 cases described in the literature with the prevention of recurrence aimed at psychological treatment. PRESENTATION OF CASE: The patient is a 7 year-old girl with a history of trichotillomania with trichophagia as a young child who presented with abdominal pain, nausea, and vomiting, consistent with a gastric outlet obstruction...

Proton pump inhibitors (PPIs) are known as a class of pharmaceutical agents that target H(+)/K(+)-ATPase, which is located in gastric parietal cells. PPIs are widely used in the treatment of gastric acid-related diseases including peptic ulcer disease, erosive esophagitis and gastroesophageal reflux disease, and so on. These drugs present an excellent safety profile and have become one of the most commonly prescribed drugs in primary and specialty care. Except for gastric acid-related diseases, PPIs can also be used in the treatment of Helicobacter pylori infection, viral infections, respiratory system diseases, cancer and so on...

The aim of the virgin olive oil extraction process is mainly to obtain the best quality oil from fruits, by only applying mechanical actions while guaranteeing the highest overall efficiency. Currently, the mechanical methods used to extract virgin oils from olives are basically of two types: the discontinuous system (obsolete) and the continuous one. Anyway the system defined as "continuous" is composed of several steps which are not all completely continuous, due to the presence of the malaxer, a device that works in batch...

PURPOSE OF REVIEW: To review recent advances in achalasia diagnostics and therapeutics. RECENT FINDINGS: The cardinal feature of achalasia, impaired lower esophageal sphincter (LES) relaxation, can occur in association with varied patterns of esophageal contractility. The Chicago Classification distinguishes among these as follows: without contractility (type I), with panesophageal pressurization (type II), with premature (spastic) distal esophageal contractions (type III), or even with preserved peristalsis [esophagogastric junction (EGJ) outlet obstruction]...

In the emergency care field, early treatment of acute heart or respiratory failure has been a global concern. In severe cases, patients are frequently required to be on an extracorporeal membrane oxygenator (ECMO) life support. To make the ECMO system more compact and portable, we proposed a sequential flow-type centrifugal pump named the sequential flow pump (SFP). In this study, principle and basic properties of this novel blood pump were examined by computational fluid dynamic (CFD) analysis and an experimental model...

Over the past two decades there have been significant advances in the use of magnetic resonance imaging (MRI) to assess the vascular system. New imaging sequences and improvements in magnet design have enabled the creation of higher spatial resolution images. MRI is now a viable alternative imaging modality when compared to both invasive angiography and computed tomographic angiography. The use of blood pool agents has further facilitated the use of MR angiography (MRA); their high molecular weight allows for lower doses of contrast medium administration while their prolonged presence in the blood stream allows for repeated high-quality volumetric imaging of both the arterial and venous circulation...

INTRODUCTION: Herniation of abdominal viscera into the thorax may occur as a consequence of abnormal defects in the diaphragm. In adults, the most common condition relates to herniations through a weakened crural orifice via which the oesophagus normally traverses. These hiatus hernias are classified as types I-IV depending on the extent of visceral involvement. CASE REPORT: We present here a case of type IV hiatus hernia with massive mediastinal herniation of the small bowel, yet remarkable in that the stomach itself remained completely intra-abdominal...

This paper presents a novel machine vision-based auto-sorting system for Chinese cabbage seeds. The system comprises an inlet-outlet mechanism, machine vision hardware and software, and control system for sorting seed quality. The proposed method can estimate the shape, color, and textural features of seeds that are provided as input neurons of neural networks in order to classify seeds as "good" and "not good" (NG). The results show the accuracies of classification to be 91.53% and 88.95% for good and NG seeds, respectively...

Much literature examines the relationship between the spatial availability of alcohol and alcohol-related harm. This study aims to address an important gap in this evidence by using detailed outlet data to examine recent temporal trends in the sociodemographic distribution of spatial availability for different types of alcohol outlet in England. Descriptive analysis of measures of alcohol outlet density and proximity using extremely high resolution market research data stratified by outlet type and quintiles of area-level deprivation from 2003, 2007, 2010 and 2013 was undertaken and hierarchical linear growth models fitted to explore the significance of socioeconomic differences...

REVIEW
Francois G Soto-Palou, Ricardo F Sánchez-Ortiz
Abdominal straining associated with voiding dysfunction or constipation has traditionally been associated with the development of abdominal wall hernias. Thus, classic general surgery dictum recommends that any coexistent bladder outlet obstruction should be addressed by the urologist before patients undergo surgical repair of a hernia. While organ-confined prostate cancer is usually not associated with the development of lower urinary tract symptoms, a modest proportion of patients treated with radical prostatectomy may have coexisting benign prostatic hyperplasia with elevated symptom scores and hernias may be incidentally detected at the time of surgery...

PURPOSE: Overactive bladder (OAB), usually accompanied by partial bladder outlet obstruction (PBOO), is associated with detrusor overactivity (DO) which is related to the increased urinary bladder smooth muscle (UBSM) cells excitability. Small-conductance Ca(2+)-activated K(+) (SK) channels play a constitutive regulatory role of UBSM excitability and contractility. PBOO is associated with the decreased SK channels mRNA expression and the attenuated regulative effect of SK channels on UBSM contractility...

We introduce a design methodology for nonimaging, single-reflection mirrors with polygonal inlet apertures that generate a uniform irradiance distribution on a polygonal outlet aperture, enabling a multitude of applications within the domain of concentrated photovoltaics. Notably, we present single-mirror concentrators of square and hexagonal perimeter that achieve very high irradiance uniformity on a square receiver at concentrations ranging from 100 to 1000 suns. These optical designs can be assembled in compound concentrators with maximized active area fraction by leveraging tessellation...

The orthogonal pressurized planar electrochromatography (OPPEC) is an example of 2-D separation technique, in which two simultaneous and orthogonal processes of electrophoresis and chromatography are involved in the separation mechanism. In the case of preparative separation of substances characterized by different electrophoretic mobility, such separation system can be constantly fed with the sample solution and the separated components can be constantly collected at its outlet. In the paper, as opposed to the previous studies, we discuss the capabilities of OPPEC technique for preparative separation of substances characterized by the same electrophoretic mobility...

Exposure due to thoron ((220)Rn) gas and its decay products in a thorium fuel cycle facility handling thorium or (232)U/(233)U mixture compounds is an important issue of radiological concern requiring control and mitigation. Adsorption in a flow-through charcoal bed offers an excellent method of alleviating the release of (220)Rn into occupational and public domain. In this paper, we present the design, development, and characterization of a Thoron Mitigation System (TMS) for industrial application. Systematic experiments were conducted in the TMS for examining the (220)Rn mitigation characteristics with respect to a host of parameters such as flow rate, pressure drop, charcoal grain size, charcoal mass and bed depth, water content, and heat of the carrier gas...
