Practical approach to linear endoscopic ultrasound examination of the rectum and anal canal.

Standard endosonographic examination of the rectal area is usually performed with radial endoscopic ultrasound (EUS). However, in recent years, widespread availability of linear EUS for assessing various anatomical regions in the gastrointestinal tract has facilitated its use in the assessment of anorectal disorders. Currently, many rectal and anal diseases, including perianal abscesses, fistulae, polyps, and neoplastic lesions, can be well-visualized and evaluated with linear EUS.

Development, Validity, and Reliability of the Perceived Telemedicine Importance, Disadvantages, and Barriers (PTIDB) Questionnaire for Egyptian Healthcare Professionals.

Background: This study aimed to develop and investigate the psychometric properties of the Perceived Telemedicine Importance, Disadvantages, and Barriers (PTIDB) questionnaire for healthcare professionals (HCPs) in Egypt. This study was conducted in three phases: (1) development of the questionnaire, (2) preliminary testing of the questionnaire, and (3) investigation of its validity and reliability using a large survey.

Methods: A cross-sectional survey was conducted over two months.

Impact of Weight Loss on the Severity of Albuminuria in Obese Diabetic Patients Undergoing Laparoscopic Sleeve Gastrectomy and One-Anastomosis Gastric Bypass.

Aim: To examine the effect of weight-loss induced bariatric procedures on albuminuria levels among diabetic patients suffering from obesity.

Methods: Adults patients who suffer from morbid obesity and type 2 diabetes mellitus (T2DM) were included in a prospective cohort study. Subjects were scheduled to undergo laparoscopic sleeve gastrectomy (LSG) or one-anastomosis gastric bypass (OAGB).

Knowledge, Applicability, and Barriers of Telemedicine in Egypt: A National Survey.

Objectives: The study is aimed at evaluating knowledge, attitude, and barriers to telemedicine among the general population in Egypt.

Methods: A questionnaire-based cross-sectional design was carried out among the general Egyptian population. A convenience sampling method was used to approach the eligible participants from University Teaching Hospitals of eight governorates from May to July 2020.

Peroral endoscopic myotomy as treatment for Zenker's diverticulum (Z-POEM): a multi-center international study.

Background: Peroral endoscopic myotomy for the treatment of Zenker's diverticulum (Z-POEM) is a novel technique that has been described in several recent reports. This method utilizes the third space (submucosal layer) to create a tunnel to facilitate complete visualization of the septum and hence cutting it entirely. Conventional endoscopic septotomy carries the risk of recurrence due to incomplete visualization of the septum.

Endoscopic ultrasound (EUS) elastography and strain ratio, could it help in differentiating malignant from benign pancreatic lesions?

Evaluating the role of endoscopic ultrasound (EUS) elastography and strain ratio in differentiation between malignant and benign pancreatic lesions.Three hundred twenty-five patients with solid pancreatic lesions were enrolled in this prospective study from 2014 to 2017. EUS real-time elastography scoring and strain ratio were done to all patients and compared to the final diagnosis to assess its sensitivity, specificity, positive and negative predictive values (PPV and NPV) in differentiating malignant from benign lesions.

Endoscopic ultrasound and endoscopic ultrasound-guided fine needle aspiration in the diagnosis of diffuse gastrointestinal lesions with inconclusive endoscopic biopsies.

Background/aims: Many gastrointestinal tumors appearing as diffuse circumferential malignancies, for example, diffuse signet ring adenocarcinoma and lymphoma, might primarily involve the submucosal layer and hence are difficult to diagnose because they frequently yield negative endoscopic biopsies. This main aim of this study was to evaluate the accuracy of endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) in the diagnosis of diffuse gastrointestinal lesions with inconclusive endoscopic biopsies.

Materials And Methods: This prospective study included 92 patients with diffuse or circumferential gastrointestinal lesions with non-conclusive biopsies that were taken during upper or lower endoscopy.

Cholecalciferol for prophylaxis against antituberculosis therapy-induced liver disorders among naïve patients with pulmonary tuberculosis: A randomized, comparative study.

Background: Patients in countries endemic for chronic viral hepatitis are more vulnerable to antituberculosis therapy-induced liver disorders (ATT-LDs). The aim of this study was to explore the role of cholecalciferol in prophylaxis against ATT-LD among patients with pulmonary tuberculosis (TB) receiving ATT.

Material And Methods: We conducted a hospital-based, prospective, randomized, comparative study which included 300 consecutive, naïve patients with pulmonary TB eligible for ATT.

Erectile dysfunction in patients with nonalcoholic fatty liver disease.

Background And Study Aims: There is a lack of studies on erectile dysfunction (ED) in patients diagnosed with nonalcoholic fatty liver disease (NAFLD). The present study aimed to estimate the prevalence of ED in patients with NAFLD and to determine the independent predictors of ED in these patients.

Patients And Methods: We conducted a prospective, hospital-based study of 192 consecutive male patients with NAFLD.

Hookworm infection among patients with pulmonary tuberculosis: Impact of co-infection on the therapeutic failure of pulmonary tuberculosis.

Objective/background: The aim of this study is to determine the rate of hookworm infection among patients with pulmonary tuberculosis (TB) and to find out if there is a relation between hookworm infection and the therapeutic failure of pulmonary TB.

Methods: We carried out a prospective, hospital-based study. The study included 231 naïve patients with pulmonary TB, consecutively.

Solitary pancreatic metastasis from renal cell carcinoma 6 years after nephrectomy.

Metastatic cancer to the pancreas is rare and accounts for less than 2% of all pancreatic malignancies. Renal cell cancer, malignant melanoma, lung, colon and breast carcinoma are among the few tumors known to metastasize to the pancreas. The pancreas is a rare site of solitary metastasis, but it is often involved in diffuse metastatic disease.

Endoscopic Ultrasound-Guided Fine Needle Aspiration versus Percutaneous Ultrasound-Guided Fine Needle Aspiration in Diagnosis of Focal Pancreatic Masses.

Objective: Pancreatic carcinoma is one of the leading cancer morbidity and mortality world-wide. Controversy has arisen about whether the percutaneous approach with computed tomography/ultrasonography-guidance fine needle aspiration (US-FNA) or endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the preferred method to obtain diagnostic tissue. Our purpose of this study is to compare between the diagnostic accuracy of EUS-FNA and percutaneous US-FNA in diagnosis of pancreatic cancer.
