Management of endoscopic complications is a pertinent aspect of patient care that has received great attention in the past decade due to advancements and increases in complexity of therapeutic endoscopy. Working groups from various institutions such as American Society for Gastrointestinal Endoscopy (ASGE) and European Society of Gastrointestinal Endoscopy have devised detailed guidelines and management algorithms. Three main factors that contribute to endoscopic complications are patient, operator, and type of procedure. No one rule suits all;hence endoscopic complication management must be customized to individual patients. Comprehensive knowledge of patient, machine/device, and its interrelationship must be in place to manage endoscopic complications.
Therapeutic endoscopic ultrasound (EUS) became possible after the advent of the linear echoendoscope and the EUS guided fine needle aspiration. Over the past two decades, the indications for therapeutic EUS have expanded and evidence regarding its utility has been steadily accumulating. Randomized studies have shown EUS to be effective for cancer pain relief (celiac plexus neurolysis), pancreatic fluid collection drainage, and biliary drainage. Prospective studies have shown EUS-guided biliary drainage to be safe and effective in patients with failed ERCP. There is evidence to suggest that EUS is effective for pancreatic duct drainage, gallbladder drainage, and drainage of pelvic collections. EUS may also be useful for targeted cancer treatment via brachytherapy, radiofrequency ablation, or injection therapy. Therapeutic EUS is likely to play an increasingly important role in endoscopic therapy of gastrointestinal diseases in the near future.
In environmental studies, the mineralogical composition of sediments is an important indicator. In combination with other indicators, they contribute to the understanding of changes in sediment sourcing as well as in weathering and depositional processes. Fourier transform infrared spectroscopy (FT-IR) spectra contain information on mineralogical composition because each mineral has a unique absorption pattern in the mid-IR range. In this study, total of sixty five sediment samples were collected from different locations of the Kalrayanhills, part of Eastern ghats, South India, lies between the north latitudes 11° 36’ and 12° 01’ N and the east longitudes 78° 29’ and 78° 54’ E. Twenty three minerals are identified using FT-IR analysis. Obtained minerals are confirmed by X-ray diffraction (XRD) analysis.The relative distribution of major minerals was determined by calculating extinction co-efficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
