- Abstract
BACKGROUND: Intestinal ultrasound (IUS) is a valuable tool for assessment of Crohn's disease (CD). However, there is no widely accepted luminal disease activity index. AIMS: To identify appropriate IUS protocols, indices, items, and scoring methods for measurement of luminal CD activity and integration of IUS in CD clinical trials. METHODS: An expert international panel of adult and paediatric gastroenterologists (n = 15) and radiologists (n = 3) rated the appropriateness of 120 statements derived from literature review and expert opinion (scale of 1-9) using modified RAND/UCLA methodology. Median panel scores of 1 to ≤3.5, >3.5 to <6.5 and ≥6.5 to 9 were considered inappropriate, uncertain and appropriate ratings respectively. The statement list and survey results were discussed prior to voting. RESULTS: A total of 91 statements were rated appropriate with agreement after two rounds of voting. Items considered appropriate measures of disease activity were bowel wall thickness (BWT), vascularity, stratification and mesenteric inflammatory fat. There was uncertainty if any of the existing IUS disease activity indices were appropriate for use in CD clinical trials. Appropriate trial applications for IUS included patient recruitment qualification when diseased segments cannot be adequately assessed by ileocolonoscopy and screening for exclusionary complications. At outcome assessment, remission endpoints including BWT and vascularity, with or without mesenteric inflammatory fat, were considered appropriate. Components of an ideal IUS disease activity index were identified based upon panel discussions. CONCLUSIONS: The panel identified appropriate component items and applications of IUS for CD clinical trials. Empiric evidence, and development and validation of an IUS disease activity index are needed.

Background Acute diarrhoea is a common cause of illness and death among children in low- to middle-income settings. World Health Organization guidelines for the clinical management of acute watery diarrhoea in children focus on oral rehydration, supplemental zinc and feeding advice. Routine use of antibiotics is not recommended except when diarrhoea is bloody or cholera is suspected. Young children who are undernourished or have a dehydrating diarrhoea are more susceptible to death at 90 days after onset of diarrhoea. Given the mortality risk associated with diarrhoea in children with malnutrition or dehydrating diarrhoea, expanding the use of antibiotics for this subset of children could be an important intervention to reduce diarrhoea-associated mortality and morbidity. We designed the Antibiotics for Childhood Diarrhoea (ABCD) trial to test this intervention. Methods ABCD is a double-blind, randomised trial recruiting 11,500 children aged 2–23 months presenting with acute non-bloody diarrhoea who are dehydrated and/or undernourished (i.e. have a high risk for mortality). Enrolled children in Bangladesh, India, Kenya, Malawi, Mali, Pakistan and Tanzania are randomised (1:1) to oral azithromycin 10 mg/kg or placebo once daily for 3 days and followed-up for 180 days. Primary efficacy endpoints are all-cause mortality during the 180 days post-enrolment and change in linear growth 90 days post-enrolment. Discussion Expanding the treatment of acute watery diarrhoea in high-risk children to include an antibiotic may offer an opportunity to reduce deaths. These benefits may result from direct antimicrobial effects on pathogens or other incompletely understood mechanisms including improved nutrition, alterations in immune responsiveness or improved enteric function. The expansion of indications for antibiotic use raises concerns about the emergence of antimicrobial resistance both within treated children and the communities in which they live. ABCD will monitor antimicrobial resistance. The ABCD trial has important policy implications. If the trial shows significant benefits of azithromycin use, this may provide evidence to support reconsideration of antibiotic indications in the present World Health Organization diarrhoea management guidelines. Conversely, if there is no evidence of benefit, these results will support the current avoidance of antibiotics except in dysentery or cholera, thereby avoiding inappropriate use of antibiotics and reaffirming the current guidelines.

Anil Kumar Asthana,1 John Samuel Lubel2,31Department of Gastroenterology, The Alfred Hospital, Melbourne, 2Department of Gastroenterology and Hepatology, Eastern Health, 3Eastern Health Clinical School, Monash University, Melbourne, VIC, AustraliaAbstract: Biological therapies are used extensively for malignant (eg, lymphoma) and autoimmune (eg, rheumatoid arthritis) conditions. These agents include anti-tumor necrosis factor antagonists, such as infliximab, and B-cell-depleting therapies, such as rituximab. In the past decade, there has been an explosion in the types and numbers of agents being used. One of the known risks with these agents is infection. In particular, there is increasing awareness regarding latent virus reactivation. This occurs when a latent virus is reactivated into its active replicative phase as a result of an internal or external trigger, such as immunosuppression. It is challenging, however, to quantitatively attribute the risk of reactivation to biological therapy alone because the underlying malignant or autoimmune condition could also be a contributing factor. There is well documented evidence regarding the reactivation of viruses such as hepatitis B virus and cytomegalovirus with drugs such as rituximab. Long-term data are lacking; such data are essential to guide risk stratification and chemoprophylaxis. Universally accepted viral screening guidelines prior to commencement of immunosuppression are lacking. As an example, the US Centers for Disease Control and Prevention have published recommendations regarding hepatitis B virus screening prior to commencing immunosuppression, but this action has not translated into universally accepted guidelines. Some of the other relevant viruses involved include cytomegalovirus, hepatitis C virus, varicella zoster virus, Epstein–Barr virus, and other members of the herpes family. This article reviews the current literature on the risk of latent viral reactivation with biological therapy, such as anti-tumor necrosis factor and anti-B-cell drugs, with an emphasis on autoimmune conditions.Keywords: latent viruses, autoimmune conditions, biological therapies, reactivation

- Abstract
This study addresses the pressing issue of high arsenic (As) contaminations, which poses a severe threat to various life forms in our ecosystem. Despite this prevailing concern, all organisms have developed some techniques to mitigate the toxic effects of As. Certain plants, such as bryophytes, the earliest land plants, exhibit remarkable tolerance to wide range of harsh environmental conditions, due to their inherent competence. In this study, bryophytes collected from West Bengal, India, across varying contamination levels were investigated for their As tolerance capabilities. Assessment of As accumulation potential and antioxidant defense efficiency, including SOD, CAT, APX, GPX etc. revealed Marchantia polymorpha as the most tolerant species. It exhibited highest As accumulation, antioxidative proficiency, and minimal damage. Transcriptomic analysis of M. polymorpha exposed to 40 μM As(III) for 24 and 48 h identified several early responsive differentially expressing genes (DEGs) associated with As tolerance. These includes GSTs, GRXs, Hsp20s, SULTR1;2, ABCC2 etc., indicating a mechanism involving vacuolar sequestration. Interestingly, one As(III) efflux-transporter ACR3, an extrusion pump, known to combat As toxicity was found to be differentially expressed compared to control. The SEM-EDX analysis, further elucidated the operation of As extrusion mechanism, which contributes added As resilience in M. polymorpha. Yeast complementation assay using Δacr3 yeast cells, showed increased tolerance towards As(III), compared to the mutant cells, indicating As tolerant phenotype. Overall, these findings significantly enhance our understanding of As tolerance mechanisms in bryophytes. This can pave the way for the development of genetically engineered plants with heightened As tolerance and the creation of improved plant varieties., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Context: Concurrent chemoradiotherapy is considered a standard of care for patients with carcinoma anal canal. Being an unusual malignancy, there is limited Indian data regarding survival outcomes and prognostic factors., Aim: To evaluate survival outcomes and associated prognostic factors in patients with carcinoma anal canal treated with radical intent., Methods and Material: Patients with squamous cell carcinoma of the anal canal, treated with radical intent between 2015 and 2019 were included in the study. Data regarding the baseline characteristics of the patients and treatment outcomes were collected and analyzed. Survival rates were estimated using Kaplan-Meier method. To determine survival difference between the groups, log-rank test was used. Multivariate analyses were performed with Cox proportional hazard models and P value < 0.05 was considered significant., Results: Forty-two patients were identified after applying suitable eligibility criteria. The median age was 55 years (range: 26-80 years).The median follow-up duration was 23.5 months (range: 1.9-51.9 months). The 3-year overall survival (OS), disease-free survival (DFS), and locoregional (LRC) were 78.5%, 53.1%, and 66.4%, respectively. On multivariate analysis, inferior DFS was significantly affected by lack of concurrent chemotherapy (CT) (hazard ratio [HR], 11.50; 95% confidence interval [CI], 1.92-68.78; P = 0.007) and radiotherapy (RT) dose of 45 Gy or less (HR, 35.96; 95% CI, 6.32-204.56; P = 0.000)., Conclusion: For patients of carcinoma anal canal, concurrent CT and RT dose are independent prognostic factors influencing DFS., (Copyright © 2023 Copyright: © 2023 Journal of Cancer Research and Therapeutics.)

- Abstract
Introduction: The incidence of colorectal cancer in young adults is on an increasing trend. It is observed that this subgroup of patients has an aggressive disease and carries a poorer prognosis compared to its older counterpart. This study aimed to analyze the incidence, treatment outcome, and prognostic factors in adolescents and young adults with rectal cancer attending a tertiary cancer center in North India., Materials and Methods: We retrospectively analyzed 50 patients of histologically proven rectal cancer, aged up to 30 years, treated at our center between 2015 and 2019. The clinical, demographic, and pathological parameters were studied in all these patients. Kaplan-Meier survival analysis was used to find out survival. Univariate analysis was performed to assess prognostic factors., Results: The incidence was 26.4% at our center with a median age of 28 years. Bleeding per rectum was the commonest complaint. Most of them had signet ring cell histology (26%). The median overall survival was 16 months. Survival was significantly better in patients having bleeding per rectum as an initial complaint (P = 0.009), absence of lymphovascular invasion (LVI) (P = 0.005), and perineural invasion (PNI) (P = 0.002), who received complete planned treatment compared to patients who could not receive either of the modality (P < 0.001). Patients who did not receive radiotherapy (RT) had the worst outcomes compared to those who received RT in any form. RT dose of 50.4 Gy was found to be superior as compared to other schedules. There was no significant difference in survival with gender, tumor stage, grade, type of surgery, or chemotherapy regimen., Conclusion: The majority of patients presented in an advanced stage. Therefore, bleeding per rectum should be properly and timely investigated in all these young patients. Early detection and complete treatment are paramount to improving the outcome., (Copyright © 2023 Copyright: © 2023 Journal of Cancer Research and Therapeutics.)

- Abstract
Purpose: The study was done to evaluate the role of adjuvant therapy in curatively resected Stage II and III gallbladder carcinoma (GBC)., Materials and Methods: This was a retrospective analysis of patients of GBC registered between 2008 and 2017 in outpatient department of a tertiary cancer hospital in India. Patients who had any of the following adjuvant treatment after radical surgery: (a) external beam radiotherapy (RT) alone, (b) chemotherapy (CT) alone, and (c) RT with CT (CRT) were considered for the study., Results: A total of fifty patients could meet the selection criteria. It was seen that seven patients were treated with RT, 20 with CT, and 23 with CRT. Median follow-up for patients who were alive was 26.7 months. Nineteen patients had locoregional failure while eight had distant failure. Patients treated with CRT had a significantly better mean overall survival compared to those treated with RT or CT (44.0 months, 12.5 months, and 15.1 months, respectively; P = 0.003). Similarly, mean disease-free survival was superior in CRT arm compared to RT and CT arms (43.6 months, 9.6 months, and 12.4 months, respectively; P = 0.002)., Conclusions: Adjuvant CRT had better survival outcome compared to patients treated with either RT or CT with Stage II and III disease after curative cholecystectomy., Competing Interests: None

- Abstract
Aim: The aim of this study is to identify an ideal location of isocenter in intensity-modulated radiotherapy (IMRT) treatment plans., Materials and Methods: A total of 28 clinical target volumes and 4 English capital letters (C, L, T, and H) target volumes were considered in this study. Two IMRT treatment plans were generated for each target volume in the ECLIPSE
TM treatment planning system (TPS), first one with isocenter automatically placed (ISOAUTO ) by TPS and the second one with geometric center-based isocenter (ISOGEOM ). The geometric center of a cuboid volume, which was formed encompassing around the target volume in sagittal, transverse, and frontal planes, is considered as the geometric center of the target volume as well as the isocenter (ISOGEOM ) of the IMRT plans. While performing the IMRT treatment plans using the beam angle optimization and dose volume optimization, the normal tissue objectives and target volume objectives were kept similar in both the plans. The dosimetrical parameters between the two groups of plans were compared., Results: The distance between ISOGEOM and ISOAUTO ranged from 0.16 cm to 3.04 cm with a mean and median of 0.85 cm and 0.69 cm, respectively. The ISOGEOM -based IMRT plans exhibited statistically significant advantages in total monitor units reduction (100% of cases, P ≤ 0.001), total number of field reduction (66% of cases, P ≤ 0.001), and reduction of patient mean dose (69% of cases, P ≤ 0.001) over ISOAUTO -based IMRT plans. The conformity index, homogeneity index and target mean dose were comparable between both group of plans., Conclusion: Significant dosimetrical advantages may be observed, when the geometric centroid of target volume is considered as isocenter of IMRT treatment plan., Competing Interests: None- Published

- Abstract
Gastrointestinal ultrasound is a practical, safe, cheap and reproducible diagnostic tool in inflammatory bowel disease gaining global prominence amongst clinicians. Understanding the embryological processes of the intestinal tract assists in the interpretation of abnormal sonographic findings. In general terms, the examination principally comprises interrogation of the colon, mesentery and small intestine using both low-frequency and high-frequency probes. Interpretation of findings on GIUS includes assessment of bowel wall thickness, symmetry of this thickness, evidence of transmural changes, assessment of vascularity using Doppler imaging and assessment of other specific features including lymph nodes, mesentery and luminal motility. In addition to B-mode imaging, transperineal ultrasonography, elastography and contrast-enhanced ultrasonography are useful adjuncts. This supplement expands upon these features in more depth., Competing Interests: Conflict-of-interest statement: No potential conflicts of interest. No financial support.

- Abstract
Introduction: In endodontics, despite careful instrumentation and antimicrobial irrigation, root canals still harbor cultivable microorganisms. Such cases require intra canal medicament that eliminates the microbial inhabitants from the canals. Recent trend advocates the use of herbal extracts due to easy availability, cost-effectiveness, low toxicity, and lack of microbial resistance. Hence, in the present study, Neem , Tulsi , and Guduchi extracts were used as intracanal medicaments., Aim: This study aimed to evaluate and compare the antibacterial efficacy of Neem , Tulsi , Guduchi extracts, and chlorhexidine against Enterococcus faecalis , when used as intracanal medicaments., Materials and Methods: One hundred and twenty-five extracted human teeth, inoculated with E. faecalis , were divided into four experimental groups and a control group ( n = 25 in each group). The experimental groups were treated with chlorhexidine, Neem , Tulsi , and Guduchi extracts and their antibacterial property was evaluated by estimating microbial counting (CFU/ml)., Results: The reduction in bacterial count for chlorhexidine, Neem , Tulsi , and Guduchi groups was 60.76%, 51.98%, 37.73%, and 34.93%, respectively. Statistically significant difference in reduction of bacterial count was observed in all the groups, when compared with the control group., Conclusion: Among all the herbal extracts, Neem was found to be the most potent medicament followed by Tulsi and Guduchi . However, chlorhexidine was found to be at epic., Competing Interests: There are no conflicts of interest.

- Abstract
Introduction: Bio-Medical Waste (BMW) management is of utmost importance as its improper management poses serious threat to health care workers, waste handlers, patients, care givers, community and finally the environment. Simultaneously, the health care providers should know the quantity of waste generated in their facility and try to reduce the waste generation in day-to-day work because lesser amount of BMW means a lesser burden on waste disposal work and cost saving., Aim: To have an overview of management of BMW in a tertiary care teaching hospital so that effective interventions and implementations can be carried out for better outcome., Materials and Methods: The observational study was carried out over a period of five months from January 2016 to May 2016 in Chhatrapati Shivaji Subharti Hospital, Meerut by the Infection Control Team (ICT). Assessment of knowledge was carried out by asking set of questions individually and practice regarding awareness of BMW Management among the Health Care Personnel (HCP) was carried out by direct observation in the workplace. Further, the total BMW generated from the present setup in kilogram per bed per day was calculated by dividing the mean waste generated per day by the number of occupied beds., Results: Segregation of BMW was being done at the site of generation in almost all the areas of the hospital in color coded polythene bags as per the hospital protocol. The different types of waste being collected were infectious solid waste in red bag, soiled infectious waste in yellow bag and sharp waste in puncture proof container and blue bag. Though awareness (knowledge) about segregation of BMW was seen in 90% of the HCP, 30%-35% did not practice. Out of the total waste generated (57912 kg.), 8686.8 kg. (15%) was infectious waste. Average infectious waste generated was 0.341 Kg per bed per day. The transport, treatment and disposal of each collected waste were outsourced and carried out by 'Synergy' waste management Pvt. Ltd., Conclusion: The practice of BMW Management was lacking in 30-35% HCP which may lead to mixing of the 15% infectious waste with the remaining non-infectious. Therefore, training courses and awareness programs about BMW management will be carried out every month targeting smaller groups.

Choudhary S and Asthana AK
- Abstract
Background: Gallbladder carcinoma (GBC) has the propensity to fail at loco-regional (LR) and distant sites despite aggressive radical surgery. Adjuvant therapy in the form of radiotherapy (RT), systemic chemotherapy (CT) and chemoradiation (CRT) is the usual practice. Due to rarity of this disease, there is limited evidence to suggest the type of adjuvant treatment which should be offered to the patients., Aim: The study was conducted to evaluate the impact of adjuvant treatment on curatively resected GBC patients., Settings and Design: Histological proven patients of GBC registered between June, 2008 and July, 2014 were identified from our hospital database and retrospective analysis was done., Materials and Methods: Patients of GBC who had curative resection followed by adjuvant treatment as RT alone, CT alone or CRT were included in the study., Statistical Analysis: Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) and disease free survival (DFS) were evaluated using Cox Regression Method and Kaplan Meier plot., Results: We identified 33 patients of which 23 were Stage I or II disease (Early disease) and the remaining 10 were Stage III or IV disease (Advanced disease). All except one patient had adenocarcinoma. A total of 5 patients were treated with RT alone while 16 patients received CT alone. The remaining 12 patients were treated with CRT. Median follow-up period was 8.5 months. At analysis 4 were alive while the remaining 29 were dead due to disease. With regard to "Early disease" patients who had RT alone, CT alone and CRT, the median OS was 22.3, 10.3 and 15.2 months respectively (p = .440). Cohort of patients with "Advanced disease" who were treated with CT alone and CRT the median OS was 7.5 and 7.0 months respectively (p = .643). On multivariate analysis none of the prognostic factors had an adverse impact on survival., Conclusion: The impact of adjuvant treatment in the form of RT, CT or CRT after curative resection in GBC patients was seen in terms of improved survival but was not statistically significant.

- Abstract
Context: Carbapenemase production is an important mechanism responsible for carbapenem resistance., Aims: Phenotypic detection and differentiation of types of carbapenemase in carbapenem resistant Enterobacteriaceae is important for proper infection control and appropriate patient management., Settings and Design: We planned a study to determine the occurrence of Class A Klebsiella pneumoniae carbapenemase (KPC type) and Class B Metallo-β-lactamase (MBL type) carbapenemase in hospital and community., Materials and Methods: Clinical isolates of Escherichia coli and Klebsiella species and simultaneously evaluate different phenotypic methods for detection of carbapenemases., Results: It was observed that 20.72% clinical isolates of E. coli and Klebsiella spp. were resistant to carbapenem on screening of which, 14.64% were E. coli and 29.69% were Klebsiella spp. Using phenotypic confirmatory tests the occurrence of carbapenemase production was found to be 87.01% in E. coli and 91.51% in Klebsiella spp. using both modified Hodge test (MHT) and combined disk test (CDT) using imipenem-ethylenediaminetetraacetic acid., Conclusions: Both MBL and KPC type carbapenemases were seen among clinical isolates of E. coli and Klebsiella spp. CDT is simple, rapid and technically less demanding procedure, which can be used in all clinical laboratories. Supplementing MHT with CDT is reliable phenotypic tests to identify the class A and class B carbapenemase producers.

- Abstract
Background and Aim: Crohn's disease is a life-long inflammatory disease which can impair quality of life, in particular in patients with psychiatric co-morbidities such as depression and anxiety. The aim of this prospective cohort study was to assess the prevalence of depression and anxiety and related risk factors in patients with quiescent Crohn's disease., Methods: A consecutive series of adult patients with confirmed diagnosis of Crohn's disease, in clinical remission, were included and investigated during ambulatory visits using a standard questionnaire assessing demographic and clinical features of the disease. Within 1 month after the ambulatory visit, all patients were interviewed by phone to assess the presence of psychiatric disorders using standardized questionnaires. The questionnaire assessed the development of psychiatric disorders after the diagnosis of Crohn's disease, the use of antidepressant or antianxiety therapy and current anxiety or depression by means of the Hospital Anxiety and Depression Scale., Results: One hundred and ninety-five patients were included. Seventy-two (36.9 %) patients showed anxiety and/or depression symptoms, 46 (23.6 %) patients showed anxiety symptoms, 6 (3.1 %) patients showed depression symptoms and 20 (10.3 %) patients showed both symptoms. Forty-eight of these patients (58 %) were without any antidepressive or antianxiety treatment. Anxiety with or without depression was significantly correlated with female sex (p = 0.017), history of perianal disease (p = 0.003) and perianal surgery (p = 0.042)., Conclusion: Anxiety is a frequent, often untreated, condition in patient affected by Crohn's disease in clinical remission. Female sex, history of perianal disease and perianal surgery are major risk factors for anxiety.

26. C-Reactive Protein (CRP) and its Association with Periodontal Disease: A Brief Review.
- Author

Bansal T, Pandey A, D D, and Asthana AK
- Abstract
Periodontal disease is a chronic infection of the gums characterised by a loss of attachment between the tooth and bone, and bone loss. C-reactive protein (CRP) elevation is a part of the acute phase response to acute and chronic inflammation. Many epidemiological studies have shown that serum CRP levels were elevated in patients with chronic periodontitis. CRP levels increase to hundreds of μg/ml within hours following infection. It out-performs erythrocyte sedimentation rate (ESR) in terms of responsiveness and specificity for inflammation. While CRP elevation is suggestive of inflammation or infection in the appropriate clinical context, it can also occur with obesity and renal dysfunction. Conversely, a lack of CRP elevation in inflammation may be seen with hepatic failure, as well as during flares of conditions such as systemic lupus erythematosus.

- Abstract
Aim: This study was performed for the rapid identification of Mycobacterium tuberculosis complex and its resistance to rifampicin and isoniazid, directly from the sputum samples of pulmonary tuberculosis patients., Materials and Methods: A commercially available genotype MTBDR plus assay was used for the identification and detection of mutations in Mycobacterial isolates. A total of 100 sputum samples of pulmonary tuberculosis patients were analyzed by using the genotype MTBDR plus assay. The MTBDR plus assay is designed to detect the mutations in the hotspot region of rpoB gene, katG and regulatory region of inhA gene., Results: The genotype MTBDR plus assay detected 22% multidrug resistant (MDR), 2% rifampicin (RMP) monoresistant and 1% isoniazid (INH) monoresistant isolates. In 22 MDR isolates, the codons most frequently involved in RMP-associated mutations were codon 531 (54.55%), 516 (31.82%) and 526 (13.63%), and 90.90% of MDR isolates showed KatG S315T mutations and 9.1% showed inhA C-15T mutations associated with INH resistance., Conclusion: The new genotype MTBDR plus assay represents a rapid, reliable tool for the detection of MDR-TB, wherein results are obtained in 5 h allowing early and appropriate treatment, which is essential to cut the transmission path and reduce the spread of MDR-TB. The genotype MTBDR plus assay can readily be included in a routine laboratory work for the early diagnosis and control of MDR-TB.

- Abstract
Background: AmpC beta lactamases are cephalosporinases that confer resistance to a wide range of beta lactam drugs thereby causing serious therapeautic problem. As there are no CLSI guidelines for detection of AmpC mediated resistance in Gram negative clinical isolates and it may pose a problem due to misleading results, especially so in phenotypic tests. Although cefoxitin resistance is used as a screening test, it does not reliably indicate AmpC production., Materials and Methods: We planned a study to determine the occurrence of AmpC beta lactamase in hospital and community, clinical isolates of Escherichia coli and simultaneously evaluate different phenotypic methods for detection of AmpC beta lactamases., Results: It was observed that 82.76% isolates were ESBL positive and 59% were cefoxitin screen positive. Using phenotypic confirmatory tests the occurrence of Amp C beta lactamases was found to be 40% and 39% by inhibitor based method using boronic acid (IBM) and modified three dimensional test (M3D) respectively., Conclusion: Both the test showed concordant result. Co-production was observed in 84.62% isolates Screening of ESBL and Amp C can be done in routine clinical microbiology laboratory using aztreonam and IBM respectively as it is a simple, rapid and technically less demanding procedure which can be used in all clinical laboratories.

- Abstract
Background: A retrospective analysis of all cancer patients attending the radiotherapy outpatient department (OPD) of a single unit during the period of January 2005 till December 2006 was conducted to know the geographical distribution and incidence of the most common cancers, their stage of presentation, treatment compliance among the patients and follow-up., Materials and Methods: A total of 4,484 patients were registered in the Institute of Medical Sciences, Banaras Hindu University during the period of January 2005- December 2006; of which 1,975 registered in an individual unit were included for the retrospective analysis., Results: Most of the patients hailed from the various districts of UP and Bihar. Females outnumbered males with a ratio of 1.33:1. Females mostly belonged to the age group of 40-59 years; whilst males were a decade older. Major cancer sites in females were cervix and breast followed by head and neck. Leading cancer sites in males were head and neck, brain, bone, soft tissue and lung. Most of the cases presented in advanced stage of disease (74%). Squamous cell carcinoma was the most common histopathology (56%). A significant proportion of patients defaulted after undergoing preliminary investigations (16%). Only 53.9% of females and 58.5% of males took treatment out of which 68% and 63% completed the prescribed treatment. Compliance with follow-up was poor., Conclusions: The outcome of this study will significantly help us to define region specific strategies needed for cancer management in eastern Uttar Pradesh.

- Abstract
Variations in the formation of the median nerve are of interest to anatomists, radiologists, and surgeons. These variations may be vulnerable to damage in surgical operations, but their knowledge also helps in the interpretation of a nervous compression having unexplained clinical symptoms. We studied the variation in the formation of the median nerve in 87 cadavers, i.e. 174 upper limbs of formalin preserved cadavers at the department of Anatomy, Subharti medical college. We observed an additional root taking part in the formation of the median nerve in 26.4% of upper limbs, unusual low formation of the median nerve in the arm in front of the brachial artery in 18.4% of upper limbs, and median nerve formation medial to the axillary artery in 10.3% of upper limbs. Knowledge of such anatomical variations is of interest to the anatomist and clinician alike. Surgeons who perform procedures involving neoplasm or trauma repair need to be aware of these variations.

- Abstract
Classically, a single renal artery arising from the abdominal aorta supplies the respective kidney on each side. Near the hilum of the kidney each renal artery divides into anterior and posterior branchs, which in turn divide into segmental arteries supplying the different renal segments. A total of 84 formalin fixed cadavers (73 male and 11 female, 168 kidneys in total) constituted the material for the study. During routine abdominal dissection conducted for medical undergraduates, the kidneys and their arteries were explored and variations in morphological patterns of renal arteries were noted. We observed superior polar renal artery in 22.6% cases. Superior polar renal arteries had different sources of origin. In 10.7% of cases it came directly from the abdominal aorta as an accessory renal artery; in 5.4% of cases as a direct branch from the main renal artery; in 3.6% of cases from the superior hilar renal artery (from one of the duplicated renal arteries); and in 3.0% of cases from a segmental branch of the renal artery. We also observed unusual hilar branching patterns of renal arteries, which included a fork pattern in 11.3% of cases, ladder pattern in 7.7% of cases, net pattern in 5.9% of cases, and triplicate in 3.0% of cases. Understanding the anatomy of vascular variations of the kidney is essential for the clinician to be able to perform procedures such as renal transplantation, interventional radiological procedures, and renal vascular operations more safely and efficiently.

- Abstract
Leprosy is a chronic inflammatory disease caused by Mycobacterium leprae, which affects not only the peripheral nerves and skin but also various internal viscera through the hematogenous spread, especially in lepromatous cases. The micropathological changes in epidermis, nerves and skin appendages from lesioned skin reported by various authors but reports of involvement of apparently normal sites are few. We investigated skin biopsy material taken from 130 patients with clinically diagnosed leprosy. Biopsies were taken at least 10 cm away from site of lesion. Hematoxylin and Eosin staining and Harada's modified Allochrome method for acid-fast bacilli were applied for histological investigations. The pattern of leprosy among the patients were indeterminate in 53 cases (40.8%), tuberculoid in 29 cases (22.3%), borderline tuberculoid in 14 cases (10.8%), borderline leprosy in ten cases (7.7%), borderline lepromatous in nine cases (6.9%) and lepromatous leprosy in 15 cases (11.5%). The changes were seen in sub-epidermal zone of normal appearing skin in all type of leprosy, but involvement was greater at the lepromatous end of the spectrum compared to tuberculoid end. Acid-fast bacillus (AFB) was seen in subepidermal zone of normal appearing site. Presence of AFB is significant as far as dissemination and transmission of disease is concerned.

- Abstract
The quality of patient care is critically influenced by the availability of accurate information and its efficient management. Radiation oncology consists of many information components, for example there may be information related to the patient (e.g., profile, disease site, stage, etc.), to people (radiation oncologists, radiological physicists, technologists, etc.), and to equipment (diagnostic, planning, treatment, etc.). These different data must be integrated. A comprehensive information management system is essential for efficient storage and retrieval of the enormous amounts of information. A radiation therapy patient information system (RTPIS) has been developed using open source software. PHP and JAVA script was used as the programming languages, MySQL as the database, and HTML and CSF as the design tool. This system utilizes typical web browsing technology using a WAMP5 server. Any user having a unique user ID and password can access this RTPIS. The user ID and password is issued separately to each individual according to the person's job responsibilities and accountability, so that users will be able to only access data that is related to their job responsibilities. With this system authentic users will be able to use a simple web browsing procedure to gain instant access. All types of users in the radiation oncology department should find it user-friendly. The maintenance of the system will not require large human resources or space. The file storage and retrieval process would be be satisfactory, unique, uniform, and easily accessible with adequate data protection. There will be very little possibility of unauthorized handling with this system. There will also be minimal risk of loss or accidental destruction of information.

Mandal A, Asthana AK, and Aggarwal LM
- Abstract
The purpose of this retrospective study is to report the radiotherapy treatment response of, and complications in, patients with cervical cancer on the basis of cumulative biologic effective dose (BED) and overall treatment time (OTT).Sixty-four (stage II - 35/64; stage III - 29/64) patients of cervical cancer were treated with combination of external beam radiotherapy (EBRT) and low dose rate intracavitary brachytherapy (ICBT). The cumulative BED was calculated at Point A (BED(10)); and bladder, rectal reference points (BED(2,5)) using the linear-quadratic BED equations.The local control (LC) rate and 5-year disease-free survival (DFS) rate in patients of stage II were comparable for BED(10) <84.5 and BED(10) >84.5 but were much higher for BED(10) >84.5 than BED(10) <84.5 (P< 0.01) in stage III patients. In the stage II patients, The LC rate and 5-year DFS rate were comparable for OTT <50 days and for OTT >50 days but were much higher in stage III patients with OTT < 50 than OTT >50 days (P< 0.001). It was also observed that patients who received BED(2.5) <105 had lesser rectal (P< 0.001) and bladder complications than BED(2.5) >105. Higher rectal complication-free survival (CFS(R)) rate, bladder complication-free survival (CFS(B)) rate and all-type late complication-free survival rate were observed in patients who received BED(2.5) < 105 than BED(2.5) >105.A balanced, optimal and justified radiotherapy treatment schedule to deliver higher BED(10) (>84.5) and lower BED(2.5) (< 105) in lesser OTT (< 50 days) is essential in carcinoma cervix to expect a better treatment outcome in all respects.

- Abstract
Beta lactamase continues to be the leading cause of resistance to beta lactam antibiotics in gram-negative bacteria. A total of 50 clinical isolates of Pseudomonas aeruginosa were studied to determine the prevalence of ESBL production in hospital strains and also to study their susceptibility to various other antimicrobial agents. ESBL production was observed in a total of 18/50 (36%) of cases. Most of the ESBL positive isolates showed resistance to 3rd generation cephalosporins including multidrug resistance (MDR) to antibiotics like piperacillin, nalidixic acid, ciprofloxacin, levofloxacin, gentamicin and tobramycin. The ESBL producers however showed good susceptibility to drugs like meropenem, gatifloxacin and amikacin.

- Abstract
Germ cell tumour, though rare, represents most common malignancy among young men aged between 15 to 35 years. In 1990's dramatic improvement has taken place in survival rate of testicular tumours (from 10% in 1970's and 90% in 1990's). This has been possible because of effective diagnostic techniques, accurate monitoring with biological markers and use of effective platinum based combination chemotherapy in its management. The most significant improvement in survival rate has occurred in advanced stage germ-cell tumours. Seminomas are sensitive to radiation therapy and NSGCT (Non Seminomatous Germ Cell Tumours). are effectively treated by combination chemotherapy of 3 drugs of which Bleomycin is most expensive and many patient can not afford it and so compliance is poor. In the present series we have tried only 2 drug regimen consisting of Platinum and Etoposide (PE). Since January 1992 to December 1994, 40 cases of testicular tumours were treated. 16 cases received PEB regimen and 24 cases were treated by PE regimen of which only 6 cases in the former and 20 cases in the later group completed the scheduled course. Patients were given 6 cycles of PE regimen (inj. Platinum 20 mg/m2 D1-D5, VP-16 (ETOPOSIDE), 100 MG/M2 1.V. D1-D5) repeated every three weeks. Final evaluation was done in June 1996. 17/20 (85%) patients on PE regiment exhibited complete regression of the disease by the end of June 1996, I was lost to follow up, and 2 of them had the disease in progressive stage and were considered for another regimen. 18 months disease free survival was 85%. Table I. Royal Marsden Staging System Stage I: Disease econfined to testes Stage II: Intradiaphragmatic node involvement A: Less than 2 cm B: 2-5 cm C: Greater than 5 cm Stage III: Supradiaphragmatic node involvement Stage IV: Extralymphatic disease Lung, Liver, Bone etc.

- Abstract
In the present investigation direction and pattern of hair distribution were observed on the dorsum of phalanges of hands in 115 male medical students from Uttar Pradesh, India. Inproximal phalanges of the hands the direction of hair showed the relation with fingers. Observation of hair from little finger to thumb revealed the changes in direction from ulnar to radial (p less than 0.05). Probability of incidence of hair distribution was also studied among the fingers of both the hands. This correlation was significant on the proximal phalanges (p less than 0.05). However, no significant correlation coefficient was observed in the middle phalanges of the hands.
