ABSTRACT
A rare kind of squamous cell cancer is called basaloid squamous cell carcinoma occurring in sixth to seventh decade of life with male predilection. It preferentially occurring in upper aerodigestive tract. Rare case reports are presented in the classical age group with a poor prognosis. A 46 year's senior old male patient showed up to otorhinolaryngology department with chief complain of growth on base on left side of tongue and supra-glottic growth. On radiological evaluation by Multislice CT Scanning, a heterogeneously enhancing mass lesion measuring approximately 25×38 mm was noted at the base of tongue. On cytological evaluation of the lesion, highly cellular smear showed malignant morphology of the cells. Histological evaluation reveals a tumour mass in which neoplastic cells were composed of two different cell types – the majority of the cells population consisted of basaloid cells with abrupt association of foci of squamous cells suggesting basaloid variant of Squamous cell carcinoma. We brought this case for acknowledgment due to its rare occurrence, lower age of presentation, poor prognostic value as well as high metastatic potential.
ABSTRACT
Chronic lymphocytic leukemia is a neoplastic entity pertaining to lymphocytes when they get accumulated in either lymph nodes thereby call as Small lymphocytic lymphoma or spilled up in the circulation of the blood. These lymphocytes are mature looking, relatively immunologically competent usually expressing B cell phenotype markers. The median age of affection of patients at the time of diagnosis is 71 years and its incidence increases with age. Its incidence in an age group <50 years is quite uncommon accounting only to 10-15% of total diagnosed cases. Here we are presenting such a rare case report of chronic lymphocytic leukaemia where age of affection is less than 40 years
ABSTRACT
Transfusion of blood and blood components could be responsible for saving millions of life each year throughout the world. However, on the other hand , an improperly screened donated blood can be a source of transfusion transmitted infections (TTIs). Some important prevalent infections are caused by human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), Treponema pallidum and malaria parasite. To study the sero-prevalence and trends of HIV viral markers amidst blood donors in Northern India.The study was carried out in the blood bank section of Department of Pathology, Era's Lucknow Medical College, Era University, Lucknow. The present study was conducted as a retrospective & prospective observational study. Retrospective data of past eight years before commencement of study (2008 to 2015) and prospective data of one and a half years (2016 and 2017) was used in the study. Data of 22192 blood donors was explored for the present study. Only 10 donors were found to be positive for HIV viral markers. Prevalence of HIV positivity was relatively much lower than that reported in contemporary studies. Nevertheless, the present study underscored the need to carry out screening of viral markers and their periodic audit in order to understand the changing trends of sero-positivity among blood donors.
ABSTRACT
Extranodal Lymphomas are most commonly located in gastrointestinal tract. The most common cause of small intestinal obstruction in children is intussusception. However GI lymphomas are a rare cause of intussusception. So we are reporting a case of extranodal lymphoma in a female child presenting as intussusception of small intestine. a 9 years old female child presented with features of subacute intestinal obstruction. On examination a lump was felt in the abdomen. On further evaluation, a computed tomography (CT) revealed a possibility of lymphoma. The bowel segment was excised and sent for histopathological examination. On gross examination a growth was seen along with satellite lesion. 10 lymph nodes were also identified. Representative sections were taken. Microscopic examination showed the presence of medium size to large size lymphoid cells. After immunohistochemical staining a diagnosis of Non Hodgkins Lymphoma (Extranodal Marginal Zone) was made. 1 lymph node was positive for tumour invasion while other 9 were showing reactive hyperplasia. Since both lymphomas and intussesception are common in pediatric age group, lymphoma should always be kept as a differential diagnosis while dealing with a case of intussusception in pediatric age group.
ABSTRACT
Rational use of corticosteroids is very essential for improving patient safety on long term use. The present study aimed to study the prescribing usage pattern of corticosteroids in a tertiary care hospital. A prospective observational study was conducted in the department of dermatology, gynecology and general medicine in a tertiary care teaching hospital for the period of 6 months (August-February). All patients receiving any category of Steroid therapy were included and the prescribing and tapering pattern of steroids were reviewed. Prescribing pattern was observed and analysed in 132 participants during the study period. Cases were collected from the departments of Dermatology, General Medicine, Pediatrics and Gynecology in Gandhi Hospital, Secunderabad. All the prescriptions containing steroids were included in this study and the parameters evaluated were gender distribution, age of the patients, types of steroids according to the route of administration, number of prescribed daily dose (PDD) where compared with defined daily dose (DDD). In the collected 132 cases, 162 times corticosteroids were prescribed. The steroid utilization was found to be more in female patients, the maximum number of cases with corticosteroids was found in Dermatology department (39.4%). Particularly Injection Dexamethasone (24.7%) and Tablet Prednisolone (24.7%) are mostly prescribed. Most drugs were prescribed rationally although some factors like improper history, drug administration time and tapering were deviating away from rationality. Although most of the drugs were prescribed rationally, involvement of a Clinical pharmacist in patient care can help in more rational prescribing along with prevention and early detection of ADRs which can directly promote drug safety and better patient outcomes.
ABSTRACT
The present investigation was undertaken to assess the biodegradation of phenol by native bacteria strains isolated from coke oven processing wastewater. The strains were designated ESDSPB1, ESDSPB2 and ESDSPB3 and examined for colony morphology Gram stain characters and biochemical tests. Phenol degrading performance of all the strains was evaluated initially. One of the strains namely ESDSPB2 was found to be highly effective for the removal of phenol, which was used as sole carbon and energy source. From an initial concentration of 200 mg l-1 it degraded to 79.84 ± 1.23 mg l-1. In turn the effect of temperature (20 to 450C), pH (5 – 10) and glucose concentration (0, 0.25 and 0.5%) on the rate of phenol degradation by that particular strain was investigated. Observations revealed that the rate of phenol biodegradation was significantly affected by pH, temperature of incubation and glucose concentration. The optimal conditions for phenol removal were found to be pH of 7 (84.63% removal), temperature, 300C (76.69% removal) and 0.25% supplemented glucose level (97.88% removal). The main significance of the study is the utilization of native bacterial strains from the waste water itself having potential of bioremediation.
ABSTRACT
Due to widespread industrial use, chromium (Cr) is considered a hazardous environmental pollutant. It is known to inhibit plant growth and development. The present study provides the evidence of the phytotoxicity of this metal on the pea (Pisum sativum L. cv Azad) plants. The plants of pea (Pisum sativum L.) were grown in refined sand under different concentrations i.e. 0.05, 0.1, 0.2, 0.3 and 0.4 mM of Cr (VI) in order to study the effect on growth and yield, photosynthetic pigments, relative water content, non-reducing sugar and protein with activity of certain enzymes like catalase, peroxidase, starch phosphorylase and ribonuclease. The analysis of the results showed that photosynthetic pigments (68.68%), relative water contents (62.77%), non-reducing sugar (66.66%) and protein (81.57%) were decrease along with reduction in plant height (52.69% ) and leaf area (50.81%) of the pea plants. However, in response to various concentration of Cr exposed plants showed significant induction of reducing and total sugars with enzymes like catalase, starch phosphorylase and ribonuclease. The translocation of Cr in various part of pea plant have been found in order of root> stem> leaves>seeds which ranged between 34.8 to 217.3 mg g-1 d.wt. (dry weight) in roots, 6.5 to 173.13 mg g-1 d.wt. in shoot, 4.2 to 74.43 mg g-1 d.wt. in leaves and 0.94 to 8.64 mg g-1 d.wt. in seeds, that is also reflected by the transfer factor of Cr from refined sand to tested species.
ABSTRACT
Humoral immune response was studied in dogs vaccinated with different tissue culture vaccines commonly used for immunization of dogs in India. The results revealed that after single dose of vaccination only 56% dogs developed protective titer (> or = 1:8). The response of the three vaccines used in the study was not similar, highlighting the need to maintain post marketing surveillance.

Background: Adenosine deaminase has been proposed to be a useful surrogate marker for tuberculosis in pleural, pericardial and peritoneal fluids. Studies have confirmed high sensitivity and specificity of Adenosine deaminase for early diagnosis of extra pulmonary tuberculosis. Aim: To assess the diagnostic level of ADA in tubercular serosal effusion and to determine its sensitivity and specificity. Methods: The study was carried out on 120 patients suffering from serosal effusion (50 pleural, 50 peritoneal, and 20 cases of pericardial effusion) . Detailed clinical history, physical examination and routine and relevant investigation of all patients including ADA estimation by GALANTI AND GIUSTI method was done. Results: ADA Level in tuberculous pleural effusion ranged from 45-160 U/L with a mean level of 100U/L and sensitivity and specificity of 100% (p<0.001, highly significant). ADA level in tuberculous peritoneal effusion ranged from 35-135 U/L with a mean level of 92U/L and sensitivity and specificity of 100% and 95% respectively (p<0.001, highly significant). ADA level in tubercular pericardial effusion ranged from 63-117 U/L with a mean level of 90U/L and sensitivity and specificity of 100% and 83.3% respectively (p<0.005, very significant).In toto serosal fluid ADA level estimation offers high degree of sensitivity and specificity of about 100% and 94.6% respectively, Conclusion: ADA was found positive with a mean value of 100U/L, 92U/L and 90 U/L in tubercular pleural, peritoneal and pericardial effusion respectively with overall 100% sensitivity and 94.6% specificity and cutoff value of 40 U/L.
ABSTRACT
PURPOSE: To test the immunogenicity of the WHO recommended "2-2-2-0-1-1" post-exposure rabies vaccination regimen in Indian subjects to determine the feasibility of replacing crude sheep brain nerve tissue rabies vaccine with modern tissue culture rabies vaccine at major anti-rabies treatment centers throughout India. METHODS: Purified chick embryo cell vaccine (PCECV) was administered in the dosage of 0.1 mL per site to 53 Indian subjects. RESULTS: All subjects produced rabies antibodies above 0.5 IU/mL by day 14 post-vaccination. Only minor adverse reactions including swelling (6.6%), erythema (5.4%) and pain (1.4%) were observed for which no treatment was required. CONCLUSIONS: This study demonstrated that PCECV is safe and highly immunogenic in Indian subjects when administered intradermally as 0.1 mL/site using the "2-2-2-0-1-1" post-exposure regimen.
