Esophageal achalasia is a primary motor disorder that presents with dysphagia secondary to esophageal body dysfunction and functional obstruction of the lower esophageal sphincter. High-resolution manometry is considered the gold standard for the diagnosis of achalasia and, according to the Chicago classification v3.0; it can be further divided into three different subtypes based on the pressurization patterns. Herein, we present the case series of 6 pediatric patients in whom high-resolution manometry was performed for the diagnosis and classification of esophageal achalasia.

Abstract: Diabetic retinopathy is the leading cause of blindness in diabetic patients. Screening of diabetic retinopathy using fundus image is the most effective way. As the time increases this DR leads to permanent loss of vision. At present, Diabetic retinopathy is still being treated by hand by an ophthalmologist which is a time-consuming process. Computer aided and fully automatic diagnosis of DR plays an important role in now a day. Data-set containing a collection of fundus images of different severity scale is used to analyze the fundus image of DR patients. Here the deep neural network model is trained by using this fundus image and five-degree classification task is performed. We were able to produce an sensitivity of 90%.

The analysis of the secondary texts obtained as a result of a linguistic experiment has allowed the author to create a degree  classification for the emergence of metalinguistic consciousness and  to compare them to personalization and depersonalization  tendencies. The classification, as well as various metaindicators,  linguistic and extralinguistic factors make it possible to create a  linguistic persona typology based on personalization and depersonalization tendencies, text generation and text  perceiving. The article features a new classification of linguistic  persona on the basis of two criteria: degrees of the emergence of  metalinguistic consciousness and text generation and perception.  The analysis conducted has revealed that types of the linguistic  persona are divided into two groups depending on the unique or  variable type of the linguistic persona established in the process of  text perceprion. This article represents results of the analysis of  texts belonging to various types of unambiguous linguistic persona.

Summary Peptic esophagitis can occur as a complication of laparoscopic Heller-Dor surgery (LHD) among patients with esophageal achalasia. The goal of this study was to identify the characteristics of patients who have developed peptic esophagitis following LHD surgery along with the risk factors associated with the occurrence of peptic esophagitis. Among the 447 cases consisting of esophageal achalasia patients who underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not peptic esophagitis occurred following surgery. We also attempted to use univariate and multivariate analyses to identify the risk factors for peptic esophagitis occurring following surgery. Esophagitis following surgery was confirmed in 67 cases (15.0%). With respect to the patient backgrounds for cases in which peptic esophagitis had occurred, a significantly higher number were male patients, with a significantly high occurrence of mucosal perforation during surgery in terms of surgical outcomes, along with a high occurrence of esophageal hiatal hernias in terms of postoperative course (P = 0.045, 0.041, and 0.022, respectively). However, there were no significant differences in terms of age, BMI, disease duration, preoperative symptoms, esophageal manometric findings, esophageal barium findings, and esophageal clearance. A multivariate analysis indicated independent risk factors for the occurrence of peptic esophagitis following LHD as being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias. Peptic esophagitis occurred following LHD in 15% of cases. Independent risk factors for the occurrence of peptic esophagitis following LHD included being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias following surgery.
