A survey of Trace Metals Determination in Hospital Waste Incinerator in Lucknow City, India
Information on the elemental content of incinerator burning of human organ, animal and medical waste is scanty in India Nineteen trace elements were analyzed in the incinerator ash from four major hospitals, one municipal waste incinerator and two R & D laboratories engaged in animal experiment in Lucknow city. Concentrations of Zinc and Lead were found to be very high in comparison to other metals due to burning of plastic products. The source of Ca, P and K are mainly bone, teeth and other animal organs. A wide variation in trace concentration of several toxic elements have been seen due to variation in initial waste composition, design of the incinerator and operating conditions
Polymeric templating synthesis of anatase TiO₂ nanoparticles from low-cost inorganic titanium sources
A novel facile and cost-effective synthesis method for anatase TiO₂ nanoparticles has been developed by using poly-acrylic acid hydrogel as template at room temperature. The newly developed synthesis method avoids the use of hazardous reagents and/or hydrothermal steps, and enables production of highly active TiO₂ nanoparticles from low cost inorganic titanium sources. The synthesized TiO₂ nanoparticles have been studied in several applications including dye-sensitized solar cells as a photoanode as well as in organics degradation of methyl orange in aqueous media. Good photocatalytic performances were obtained in both applications
Assessment of diversity and plant growth promoting attributes of rhizobia isolated from Cajanus cajan L.
Eight (8) strains of rhizobia from Pigeon pea (Cajanus cajan) were isolated and identified based on their physiological and biochemical characteristics using standard methods. Five (5) of the isolates (KCC1 toKCC5) were subjected to partial 16S rDNA gene sequencing for phylogenetic analysis. Genetic diversity was investigated using restriction patterns produced by amplified rDNA restriction analysis (ARDRA) and were placed into different clusters. They were identified as Ensifer sinorhizobium hence named as Ensifer spp. KCC1 to KCC4. KCC5 is placed in Ensifer fredii clade. Nodulation and nitrogen fixing abilities of the isolates were confirmed by amplification of nodC and nifH genes. All of them showed indole-3-acetic acid production and phosphate solubilization activity. Only two isolates (KCC2 and KCC5) produced siderophore on CAS medium and showed strong antagonistic effect against Fusarium udum. None of the isolates produced cyanogen. The study showed that there is a considerable homogeneity amongst C. cajan root nodule isolates and can be exploited for plant growth promotion of C. cajan with effective antagonism against F. udum.Keywords: Diversity, Ensifer (Sinorhizobium) spp., pigeon pea (Cajanus cajan
Role of color Doppler ultrasound in the diagnosis of nonpalpable testes
Purpose Color Doppler ultrasound has been used for the diagnosis of torsion of testes. The purpose of this study was to evaluate the sensitivity of this noninvasive tool in detecting impalpable testes.Patients and methods Twenty-five children with nonpalpable testes were treated at the Department of Pediatric Surgery, Institute of Medical Science, Banaras, between 2007 and 2009. Color Doppler ultrasound was used for detecting the position, size, and vascularity of nonpalpable testes. These patients were subsequently revaluated by laparoscopy.Results Out of 25 cases, 15 cases were unilateral and 10 cases were bilateral (a total of 35 nonpalpable testes). The color Doppler ultrasound study successfully localized 30 of the 35 nonpalpable testes, which were confirmed by subsequent laparoscopic examination. The sensitivity of color Doppler in locating testes was 85.71% (95% confidence interval = 0.64–0.97).Conclusion Color Doppler ultrasound is an effective noninvasive method for the initial diagnosis of impalpable testes and for planning its subsequent management.Keywords: color Doppler ultrasound, laparoscopy, nonpalpable teste
Operating Manifold Services in Hospitals: A costly affair?
Manifold services form an important cost centre in hospitals. Most public sector hospitals do not have standard cost accounting system and therefore budget allocation is often difficult for support services such as the manifold. The study was conducted in a 1045 bedded tertiary care hospital in New Delhi, India with the objective of identifying the cost incurred in delivery of manifold services.This traditional costing exercise was conducted from 01 July to 30 Sept 2010 and included classification of costs, identification of the cost centres in the hospital, cost allocation and apportioning. Direct and indirect costs as well as capital and operational costs were calculated. The process of manifold services from delivery to the operational aspects was studied. Tender documents and supply orders were perused to arrive at expenditure on manifold gas pipeline system, equipment & accessories. Total annual cost of manifold services at the hospital was calculated to be 941 .Annual cost per manifold terminal unit was 0.56. The annual and daily cost per bed was deduced to be 0.87 respectively.While manifold is a vital support service, the fact remains that it is cost intensive and underutilized and often poorly planned in terms of cost effectiveness. The focus on technology in manifold services needs to be sustained
Thoracoscopic management of thoracic duct injury: Is there a place for conservatism?
Thoracic duct injury is a rare but serious complication following chest
surgeries and major neck dissections. Clinically, it can present as
cervical chylous fistula, chylothorax or chylopericardium. Without
treatment, the mortality is up to 50% and thus, early aggressive
therapy is indicated. Traditional conservative management includes
low-fat diet, parenteral nutrition, careful monitoring of fluid and
electrolytes, and drainage of the neck wound or chylothorax. Patients
with failed conservative management require definitive treatment in the
form of ligation of the thoracic duct, which has traditionally been
done by thoracotomy. The advent of Video-Assisted-Thoracoscopic-Surgery
(VATS) over the last decade has changed the approach towards the
management of numerous chest diseases. Thoracoscopic ligation of the
thoracic duct has also been reported. We report herein a case of
postoperative cervical chylous fistula managed successfully by VATS
thoracic duct ligation and present a systematic analysis of the English
literature to highlight the current trends in the management of
thoracic duct injury
Minimizing the postoperative complications of severe hypospadias using a simple technique
Background The aim of this study was to decrease complication rates in proximal hypospadias surgery.Methods A simple method of stenting using a polypropylene stent has been developed for the most severe form of hypospadias during the period from January 2008 to January 2011 in the Department of Pediatric Surgery. The total number of patients was 46. The patients were classified into group 1 (n= 23), in which a polypropylene stent was used, and group 2 (n= 23), in which a polypropylene stent was not used.Results In group 1, complications occurred in three patients (13.04%), whereas in group 2 it occurred in 12 patients (52.2%). The difference in the total number of complications between groups was highly significant (P < 0.001). In group 1, no patient needed redo surgery, and in group 2 four patients (17.39%) needed redo surgery (P < 0.05). All other patients responded to repeated dilatation in the follow-up.Conclusion Although the sample size was small, this simple modification can decrease the complication rate significantly in the most severe form of hypospadias.

Occurrence of Gastrointestinal Helminths in rabbits with special Reference to Importance of Giardia spp. as Parasitic Zoonoses
The aim of this study was to detect Giardia spp. as zoonotic helminth as Giardiosis has been recognised as the one of the important parasitic diarrhoea among children as cross transmission may occur between human and rabbits. Other helminths in rabbits may causes ill health and sometimes proved fatal. Faecal samples of 42 rabbits of different age group (1-4 years) from Nagpur and Akola regions, India were examined. The study was conducted during June to August 2008. Faecal sample examination revealed presence of mixed infection of eggs of parasites like Giardia spp. (19.04%), Trichostrongyle spp. (28.57%), Graphidium spp. (19.04%), Coccidia spp. (16.66%) and Passaluras spp. (14.28%)
Influence of firing temperature on the physical, thermal and microstructural properties of kankara kaolin clay: A preliminary investigation
In this study, natural deposits of Kankara kaolin clay were collected and investigated in order to determine physical, microstructural, thermal, and firing properties and assess clay’s suitability as starting material for various ceramic applications. Chemical analysis of the clay was performed using XRF. Mineralogical analysis and thermal analysis of the clay were conducted using XRD and thermogravimetric thermal analysis (TGA)/differential thermal analysis (DTA), respectively. In order to assess its ceramic behavior, the clay was fired at 900–1200 °C. Maturation characteristics of fired ceramics were assessed by measuring bulk density, apparent porosity, and shrinkage. It was found that main oxides in the clay are alumina, silica, and potassium oxide, while other oxides are present in trace quantities. Kaolinite, quartz, and illite are the phases found from the XRD results, while mullite ceramic phase formed at firing temperature above 1100 °C. Maturation tests showed that ceramic properties such as bulk density and shrinkage increase with temperature, while apparent porosity decreases with temperature. The results presented in this study prove that the clay is an appropriate material for producing traditional ceramics
Pediatric carcinoma of rectum - Varanasi experience
Background : Primary gastrointestinal system malignancies constitute
approximately 2% of pediatric neoplasm and of these; colorectal
carcinoma is the second most common malignancy. This is one of the
rarer diseases in children. Aim : We reviewed our records to study the
clinical features, outcome and the follow-up of this condition with
evaluation of the prognostic factors. Settings and Design: Tertiary
care Pediatric Surgery centre. Retrospective study. Materials and
Methods : The data of all patients with diagnosis of colorectal
carcinoma from January 1986 to January 2006 were reviewed. The
confirmation of the diagnosis was by biopsy from the lesion. The age,
sex, family history, clinical features, response to the treatment and
follow-up were studied. Results : There were four male patients. All
had bleeding per rectum as the presenting complaint. Three patients had
advanced disease at presentation. All the patients had signet cell
adenocarcinoma. The two patients expired and one was lost to follow-up.
One patient is alive after one year of follow up and is receiving
treatment. Conclusion : Colorectal cancer in children though rare can
be a reality, hence any children presenting with pain in abdomen along
with doubtful history of constipation and rectal bleeding should be
examined carefully with special emphasis on digital rectal examination
