Ultrasound (USG) guidance has long been used for guiding central venous catheterization. USG provides direct visualization of needle puncture through the skin into the vein. Most of the time USG guidance is just limited to puncturing of the vein and seeing guidewire entering the vein while malpositioning of catheter occurs after that which is seen later on while checking chest radiograph. Repositioning of catheter after that becomes not only difficult requiring repeated chest radiograph to reconfirm position of catheter but also increases chances of infection with repeated manipulations...

BACKGROUND: There is no universal screening method for discrimination between benign and malignant adnexal masses yet. Various authors have tried tumor markers, imaging studies, cytology but no one yet is a definite method for screening of cancer ovary, for which a combined diagnostic modality has come to practice in form of RMI. With this background we conducted our study "Evaluation of risk malignancy index and its diagnostic value in patients with adnexal masses". METHODS: The aim of the study was to determine the effectiveness of risk of malignancy index (RMI-3) in preoperative discrimination between benign and malignant masses and also to reveal the most suitable cut off value...

BACKGROUND: Insulinomas are the most common pancreatic neuroendocrine neoplasms. In spite of adequate pre-operative localisation, conventional surgical methods rely on intraoperative palpation. Intraoperative ultrasonography (IOUS) is said to aid in accurate localisation, decreases morbidity. Laparoscopic removal of pancreatic endocrine neoplasms is beneficial due to magnification and minimal invasion; however, in the absence of IOUS, error of judgement may lead to conversion to open surgery, thereby relying on 'palpation method' to localise the tumour...

The Carson River is a vital water resource for local municipalities and migratory birds travelling the Pacific Flyway. Historic mining practices that used mercury (Hg) to extract gold from Comstock Lode ore has left much of the river system heavily contaminated with Hg, a practice that continues in many parts of the world today. Between 1998 and 2013, the United States Geological Survey (USGS) collected and analyzed Carson River water for Hg and methylmercury (MeHg) concentrations resulting in a sixteen year record of unfiltered total mercury (uf...

INTRODUCTION: Pyelonephritis (PN) is a suppurative infection of the kidney, most commonly due to bacterial infection and may be either acute or chronic. Acute PN (APN) subdivided into uncomplicated and complicated. Severity of PN cannot be assessed by clinical or laboratorial parameters alone, radiological imaging such as Ultrasound (USG) abdomen, Computed Tomography (CT) is required to know the nature, extent and severity of disease and for planning interventions. AIM: The aim of this study was to compare clinical and biochemical parameters with radiological findings (USG/CT) among patients diagnosed to have PN...

Kimura's Disease (KD) is a rare chronic inflammatory disorder presenting as multiple painless solitary subcutaneous nodules, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. Because of painless nature and indolent course, there is usually a delay in the patient's presentation. KD may radiologically mimic other chronic inflammatory conditions like tuberculosis, vascular malformations and neoplasms. Clinical correlation and histological evaluation along with elevated peripheral eosinophil and serum IgE level are considered important for confirmatory diagnosis...

OBJECTIVE: Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) has been shown to be technically easy. We hypothesised that adoption of USG in-plane cannulation of the BCV as the primary approach to central venous cannulation at our institution would lead to central venous cannulation for a greater variety of indications. METHODS: We performed retrospective, descriptive comparison of all central lines placed in patients aged <16 years who underwent any surgical operation during calendar years 2012-2014 at a small, free-standing children's hospital...

BACKGROUND: Early neurological deterioration after ischemic stroke (stroke-in-evolution [SIE]) is associated with poorer outcomes. Previous studies have demonstrated a link between hydration status and the development of SIE. In this study, we tested the hypothesis that rehydration therapy, administered on the basis of urine-specific gravity (USG) findings, might reduce the development of SIE. METHODS: We conducted a single-arm prospective study of patients with acute ischemic stroke with historical controls...

Onsite wastewater treatment systems (OWTSs) can be a source of nitrogen (N) pollution in both surface and ground waters. In metropolitan Atlanta, GA, >26% of homes are on OWTSs. In a previous article, we used the Soil Water Assessment Tool to model the effect of OWTSs on stream flow in the Big Haynes Creek Watershed in metropolitan Atlanta. The objective of this study was to estimate the effect of OWTSs, including failing systems, on nitrate as N (NO-N) load in the same watershed. Big Haynes Creek has a drainage area of 44 km with mainly urban land use (67%), and most of the homes use OWTSs...

BACKGROUND: The role of thoracic paravertebral blockade (TPVB) in decreasing opioid requirements in breast cancer surgery is well documented, and there is mounting evidence that this may improve survival and reduce the rate of malignancy recurrence following cancer-related mastectomy. We compared the two techniques currently in use at our institution, the anatomic landmark-guided (ALG) multilevel versus an ultrasound-guided (USG) single injection, to determine an optimal technique. METHODS: We retrospectively reviewed records of patients who received TPVB from January 2013 to December 2014...
