GIS Based Identification and Assessment of Groundwater Quality Potential Zones in Puri City, India  [PDF]
Ritesh Vijay, Dipal Samal, P. K. Mohapatra
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.36054
Abstract: Puri city is situated on the east coast of India and groundwater is the only source available to meet the potable water supply of the city. The objective of the study was to assess the impact of anthropogenic activities on groundwater quality and to identify the groundwater potential zones for drinking water production using GIS. Major sources of groundwater contamination in the city were open discharges of domestic sewage, inadequate sewerage system, open defecation, septic tanks, soak pits, contaminated water pools and unorganized solid waste dumping. Groundwater samples were collected and analyzed during post and pre monsoon to evaluate the drinking water quality as per Indian standards. The groundwater zones were prepared based on weighted index overlay analysis by assigning the weights based on the drinking water standards under different classes of individual water quality parameters. Finally, the potential zones were identified and assessed as suitable, moderately suitable and unsuitable for domestic purpose. Based on groundwater quality and geospatial analysis, measures were suggested to protect groundwater resources.

Saudi Journal of Kidney Diseases and Transplantation , 2010,
Abstract: Xanthogranulomatous pyelonephritis (XGPN) represents an unusual suppurative gra-nulomatous reaction to chronic infection, often in the presence of chronic obstruction from a calculus. We present a case of XGPN in a horse shoe kidney in an adult. Hemi-nephrectomy of the involved side was followed by clinical improvement. The case highlights the importance of early hemi-nephrectomy in XPGN with horse shoe kidney.
Extravascular Lung Water and Acute Lung Injury
Ritesh Maharaj
Cardiology Research and Practice , 2012, DOI: 10.1155/2012/407035
Abstract: Acute lung injury carries a high burden of morbidity and mortality and is characterised by nonhydrostatic pulmonary oedema. The aim of this paper is to highlight the role of accurate quantification of extravascular lung water in diagnosis, management, and prognosis in “acute lung injury” and “acute respiratory distress syndrome”. Several studies have verified the accuracy of both the single and the double transpulmonary thermal indicator techniques. Both experimental and clinical studies were searched in PUBMED using the term “extravascular lung water” and “acute lung injury”. Extravascular lung water measurement offers information not otherwise available by other methods such as chest radiography, arterial blood gas, and chest auscultation at the bedside. Recent data have highlighted the role of extravascular lung water in response to treatment to guide fluid therapy and ventilator strategies. The quantification of extravascular lung water may predict mortality and multiorgan dysfunction. The limitations of the dilution method are also discussed. 1. Introduction In 1896, the physiologist Starling described the factors that influence fluid transport across semipermeable membranes like capillaries [1]. This description accounted for the net movement of fluids between compartments in relation to capillary and interstitial hydrostatic pressures, capillary and interstitial oncotic pressures, and coefficients of capillary permeability. Pulmonary oedema refers to the accumulation of fluid within the extravascular space of the lung and occurs when the Starling forces are unbalanced. This occurs most commonly from an increased pulmonary capillary hydrostatic pressure or an increased capillary permeability. The estimation of the severity of pulmonary oedema by chest auscultation, radiography, or arterial blood gas analysis is imprecise [2–4]. Chest auscultation may be altered by mechanical ventilation, and bedside chest radiographs in the critical care unit is subject to several technical limitations. There is poor correlation between the chest radiograph scores of pulmonary oedema and the actual amount of EVLW [5]. There is also high interobserver variability when applying the American-European Consensus Conference radiographic criteria for ARDS even amongst experts [6, 7]. Data from experimental studies suggest that EVLW on chest radiography may only be detectable when the lung water increases by more than 35% [8]. Experimental studies have also shown that arterial oxygenation decreased significantly only when the EVLW increases by more than 200% [4].
Do fluoroquinolones actually increase mortality in community-acquired pneumonia?
Ritesh Agarwal
Critical Care , 2005, DOI: 10.1186/cc3989
Abstract: First and foremost, almost 51% of the patients had a PORT (Pneumonia Patient Outcomes Research Team) score of 1–4 and did not meet the inclusion criteria as specified by the authors. Second, almost 9% of the patients received antibiotics after 8 hours, which alone is known to influence outcomes in patients with pneumonia. Two large studies showed that antibiotic administration within 4 hours [2] and 8 hours [3] of arrival in the hospital was associated with decreased mortality and length of stay. It is possible that this group of patients who received treatment after 8 hours was composed entirely of those who received fluoroquinolones, thus accounting for the adverse outcomes with this treatment. Another important point pertains to the choice of antibiotic; almost 25% of the patients in the study received piperacillin–tazobactam for CAP. This treatment should be reserved for serious hospital-acquired infections, and routinely is not necessary for management of CAP except in situations where Pseudomonas aeruginosa infection is suspected [4]. Using inappropriate antibiotics in such situations has increased the incidence of expanded-spectrum β-lactamases, which are resistant to multiple classes of antibiotics [5].Finally, the results of this retrospective study are discordant with the recently published MOXIRAPID study [6]. This multi-center trial, conducted among adult patients hospitalized with CAP, compared fluoroquinolone monotherapy (moxifloxacin) with standard therapy (cephalosporin with or without a macrolide). Although the clinical outcomes were similar in the groups, patients randomly assigned to receive moxifloxacin had rapid resolution of fever and relief of symptoms such as chest pain, as recorded in patient diary entries.EM Mortensen, MI Restrepo, A Anzueto and J PughWe appreciate Dr Agarwal's interest in our article. However, we should like to respond to the comments made.First, the statement that 51% of patients had pneumonia severity index scores of I–I

Allergic bronchopulmonary aspergillosis: Lessons for the busy radiologist
Ritesh Agarwal
World Journal of Radiology , 2011, DOI: 10.4329/wjr.v3.i7.178
Abstract: The probability of a radiologist interpreting a disease correctly is not only influenced by their training and experience but also on the knowledge of a particular entity. This editorial reviews certain myths and realities associated with radiological manifestations of allergic bronchopulmonary aspergillosis (ABPA). ABPA is a hypersensitivity disorder against the antigens of Aspergillus fumigatus. Although commonly manifesting with central bronchiectasis (CB), the disorder can present without any abnormalities on high-resolution computed tomography (HRCT) of the chest, so-called serologic ABPA (ABPA-S). HRCT of the chest should not be used in screening or in the initial diagnostic work up of asthmatics, as asthma without ABPA can manifest with findings of CB. High-attenuation mucus (HAM) is the pathognomonic sign of ABPA and is very helpful in the diagnosis of ABPA complicating asthma and cystic fibrosis. Instead of classifying ABPA based on the presence and absence of CB into ABPA-CB and ABPA-S respectively, ABPA should be classified as ABPA-S, ABPA-CB and ABPA-CB-HAM. The classification scheme based on HAM not only identifies an immunologically severe disease but also predicts a patient with increased risk of recurrent relapses.
High attenuation mucoid impaction in allergic bronchopulmonary aspergillosis
Ritesh Agarwal
World Journal of Radiology , 2010,
Abstract: Allergic bronchopulmonary aspergillosis (ABPA) is a complex hypersensitivity syndrome triggered against antigens of Aspergillus fumigatus, a fungus that most commonly colonizes the airways of patients with bronchial asthma and cystic fibrosis. It presents clinically with refractory asthma, hemoptysis and systemic manifestations including fever, malaise and weight loss. Radiologically, it presents with central bronchiectasis and recurrent episodes of mucus plugging. The mucus plugs in ABPA are generally hypodense but in up to 20% of patients the mucus can be hyperdense on computed tomography. This paper reviews the literature on the clinical significance of hyperattenuated mucus in patients with ABPA.
