Background and Aim: Epidemiology of Helicobacter pylori infection has regional variation. Effect of eradication of H. pylori on symptoms of functional dyspepsia is uncertain, and the data in Asian scenario are scanty. The study aimed to see H. pylori positivity rate in patients of functional dyspepsia and the effect of its eradication on symptoms. Methods: Randomized, double-blind, placebo-controlled study was the study design used. Patients of functional dyspepsia defined as per Rome 2 criteria were tested for H. pylori infection by rapid urease test and gastric biopsy. H. pylori-positive patients were randomly allocated to triple therapy (20 mg of omeprazole, 500 mg of clarithromycin, and 1000 mg of amoxicillin orally two times daily) and omeperazole plus identical placebo for 2 weeks. Symptoms were assessed with the weekly Likert scale.

Nitazoxanide is a safe, effective, inexpensive, and well-tolerated drug for the treatment of niclosamide- and praziquantel-resistant beef tapeworm infection.

Sequential therapy was significantly more effective than standard therapy for eradicating H. pylori infection in peptic ulcer disease in Asian patients. Side effects were similar.

Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. Endoscopic ultrasound (EUS) is often performed to evaluate idiopathic pancreatitis and has been shown to have high accuracy in diagnosis of PD. The different techniques to identify PD by linear EUS have been described differently by different authors. If EUS is done with a proper technique it can be a valuable tool in the diagnosis of PD. The anatomical and technical background of different signs has not been described so far. This article summarizes the different techniques of imaging of pancreatic duct in a suspected case of PD and gives a technical explanation of various signs. The common signs seen during evaluation of pancreatic duct in PD are stack sign of linear EUS, crossed duct sign on linear EUS, the dominant duct and ventral dorsal duct (VD) transition. Few other signs are described which include duct above duct, short ventral duct /absent ventral duct, separate opening of ducts with no communication, separate opening of ducts with filamentous communication, stacking of duct of Santorini and indirect signs like santorinecele. The principles of the sign have been explained on an anatomical basis and the techniques and the principles described in the review will be helpful in technical evaluation of PD during EUS.

Background:Tubercular lymphadenitis is the commonest extra pulmonary manifestation in cervical and mediastinal locations. Normal characteristics of lymph nodes (LN) have been described on ultrasonography as well as by Endoscopic Ultrasound. Many ultrasonic features have been described for evaluation of mediastinal lymph nodes. The inter and intraobserver agreement of the endosonographic features have not been uniformly established.Methods and Results:A total of 266 patients underwent endoscopic ultrasound guided fine needle aspiration and 134 cases were diagnosed as mediastinal tuberculosis. The endoscopic ultrasound location and features of these lymph nodes are described.Conclusion:Our series demonstrates the utility of endoscopic ultrasound guided fine needle aspiration as the investigation of choice for diagnosis of mediastinal tuberculosis and also describes various endoscopic ultrasound features of such nodes.
