Item Association of Chlamydia pneumoniae IgG and IgA antibody in coronary artery disease.(2015-01) Swetha, M; Sadananda, K S; Venkatesha, D; Anuradha, KBackground: Cardiovascular disease, resulting from atherosclerosis, is a leading cause of global morbidity and mortality. Classical risk factors explain much of the attributable risk for cardiovascular events, but other risk factors for the development and progression of atherosclerosis, which can be identified, may be important therapeutic targets. Infectious agents, such as Chlamydia pneumoniae, have been proposed as contributory factors in the pathogenesis of atherosclerosis. The present study was conducted to determine the seroprevalence of C. pneumoniae antibodies and to study the association of chronic C. pneumoniae infection with Coronary Artery Disease (CAD). Methods: The study group included 90 angiographically proven CAD patients and age and sex matched 90 normal coronaries as control group. With total aseptic precaution 3 ml blood was collected. Enzyme linked immunosorbant assay was performed for all subjects to detect the presence of IgG and IgA antibodies to Chlamydia pneumoniae (Cp). Results: IgG and IgA Cp antibodies were detected in 67.8% and 58.9% CAD patients compared to 45.6% and 11.1% controls. IgG + IgA Cp antibodies were detected in 88.9% CAD patients when compared to 50.0% controls. Seroprevalence of IgG and IgA Cp antibodies were high among CAD patients compared to controls and was found statistically significant. A significant presence of Chlamydia pneumoniae antibodies was detected in smokers, diabetes mellitus, hypertension, and dyslipidemia. Conclusion: In the present study, the seroprevalence of IgG and IgA Cp antibodies was found to be higher in CAD patients compared to controls. The present study supports the association between Chlamydia pneumoniae infection and Coronary artery disease.Item A case report of placental teratoma: an unusual primary non-trophoblastic tumor of placenta.(2005-04-09) Anuradha, K; Thomas, Sindha; Revadi, P S; Muley, Pramod RPlacental teratoma, with less than 20 cases reported in the world literature is a rare primary nontrophoblastic tumour. The exact histogenesis is still controversial, with some regarding it as a true neoplasm, while others consider it as an extreme form of fetus amorphous. Whatever its histogenesis, it is invariably benign and causes no adverse effects on the fetus or the outcome of the gestation. This case is being presented for its rarity, with a review of literature.Item CD4 count evaluation in HIV-TB co infection before and after anti-tubercular treatment.(2014-07) Kavya, S; Anuradha, K; Venkatesha, DBackground: The global impact of Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) co-infection is one of the major public health challenge. India has a very high burden of TB according to the WHO. A decrease in CD4 counts in HIV-TB co-infection leads to an increase in morbidity and mortality. Methods: Information regarding the duration of HIV, type of TB, CD4 counts before and after ATT and any associated Opportunistic Infections (OIs) were collected from the records of 100 patients with HIV-TB co-infection who attended ART centre for a period of one year. The collected data was statistically analyzed. Results: In the study group, 35 had Pulmonary Tuberculosis (PTB) and 65 had Extra Pulmonary Tuberculosis (EPTB), 40 had OIs. Mean CD4 count prior to ATT in PTB was 197 (7-940), EPTB 192 (13-683) and with OIs 129 (7-288). After completion in PTB was 300, EPTB 302 and 252 in OIs. Least CD4 count of 121 was observed in patients above 50yrs and after completion it was 133. Incidence of both EPTB and PTB was higher in males 66.2% and 62.9%, and in the age group of 31-50 yrs 50.8% and 60% (Cell counts expressed in cells/μl.). Conclusion: In our study, we found that there was significant recovery of CD4 cells following ATT. Difference in CD4 counts among patients with PTB and EPTB was not significant. There was remarkable reduction of CD4 counts in patients who had other OIs and the recovery after ATT was also marginal.Item Experimental Teaching and Interactive Computer Assisted Learning : The Student’s Viewpoint(2005-10) Medhi, B; Sukhija, M; Upadhayay, S; Bhatia, A; Anuradha, KA student view point regarding utility and present role of experimental teaching and interactive computer assisted learing was cited from three Medical Colleges of North India using a set of questionnaires. The majority of the student cited that animal experiments are important part of medical curriculum. However, computer assisted learning techniques will be useful aid in future but currently cannot replace animal experiments as the tool of choice for medical education and research.Item Herpes simplex virus 2 infection: a risk factor for HIV infection in heterosexuals.(2008-05-28) Anuradha, K; Singh, H Maan; Gopal, K V T; Rama Rao, G Raghu; Ramani, T V; Padmaja, JyothiBACKGROUND: Genital ulcerative disease is one of the risk factors for acquisition of HIV. As HSV-2 infection is currently the most common cause of genital ulcerative disease, it acts as a potential risk factor for HIV infection. The present study was undertaken to know the seroprevalence of antibodies to HSV-2 in HIV seropositive individuals and in the general population, and to ascertain if HSV-2 is a risk factor for developing HIV infection. METHODS: The study group included one hundred new HIV seropositive persons irrespective of active genital herpes or history of genital herpes. Fifty age- and sex- matched healthy volunteers were included as controls. In all patients and controls, diagnostic serology was done for HSV-2 using HSV-2-specific glycoprotein IgG2 by indirect immunoassay using the ELISA test. Statistical value 'P' was calculated using the Chi-squared test. RESULTS: Out of the 100 HIV seropositives, 66 were males and 34 were females with an age range of 20-54 years. In only 22 (19 males and 3 females) of these, positive history of genital herpes was obtained. In 49 out of the 100 HIV seropositives, IgG2 antibodies against HSV-2 were detected. In the control group, 11 out of 50 controls were seropositive for HSV-2 IgG2 antibody. There was a statistically significant association between HSV-2 and HIV seropositivity with 'P' value CONCLUSION: The high prevalence of HSV-2 seropositivity in the HIV-infected group (49%) as compared to normal controls (22%) was statistically significant. Prior HSV-2 infection could be an important risk factor for acquisition of HIV in our patients.Item Investigation of central mechanism of insulin induced hypoglycemic convulsions in mice.(2004-04-20) Anuradha, K; Hota, D; Pandhi, PInsulin produces seizures in healthy and diabetic animals. Amongst suggested mechanisms, the role of neuromodulators and neurotransmitters is not clear. The present study explores the mechanisms involved in insulin-induced convulsions. Convulsions were induced in Swiss male albino mice with graded doses of insulin. Blood sugar levels were measured prior to and after the first convulsion. Drugs like 5-HTP (5-HT precursor), pCPA (5-HT depletor), ondansetron (5-HT3 antagonist), ketanserin (5-HT, antagonist), ketamine (NMDA antagonist), 1-dopa (dopamine precursor) and reserpine (amine depletor) were studied for interaction with convulsive behaviour induced by insulin. Insulin in 2 IU/kg dose did not produce convulsions while 4 and 8 IU/kg doses produced convulsions in 50% and 100% of animals respectively. 5-HTP, ondansetron, ketanserin, ketamine and l-dopa significantly protected/inhibited animals from convulsions at all studied doses of insulin. On the contrary, pCPA and reserpine potentiated insulin induced convulsions. Insulin caused mortality in 40 and 100% animals with 4 and 8 IU/kg doses respectively. pCPA and reserpine treatments caused mortality at all doses of insulin, while other drugs did not influence insulin induced mortality. Blood sugar levels were reduced in all groups irrespective of the presence or absence of convulsions. A definitive link of serotonergic, dopaminergic and excitatory amino acid pathways in mediating insulin-induced hypoglycemic convulsions is suggested.Item Isolation of Burkholderia pseudomallei from a case of septicaemia--a case report.(2003-04-24) Anuradha, K; Meena, A K; Lakshmi, VMeliodosis, an infectious disease caused by Burkholderia pseudomallei has been recognized as an emerging infectious disease in India. The infection is under diagnosed and underreported, and hence considered a rare disease. Majority of the cases have been documented from the states with heavy rainfall. The present case being reported is a middle-aged woman who had developed a fulminant infection following exposure to stagnant floodwater in the city of Hyderabad. To the best of our knowledge, this is the first case of Melioidosis being reported from this part of the country.Item Nursing care of patients with amoebic liver abscess.(2000-12-26) Anuradha, K; Jobar, G PItem Parotid gland tuberculosis--a case report.(2004-04-22) Anuradha, K; Satish, M G; Revadi, P S; Muley, Pramod RanganathIsolated parotid gland tuberculosis in the clinical absence of tuberculosis elsewhere in the body, is a rare clinical entity. It is often misdiagnosed as parotid gland tumour in the absence of symptoms suggestive of tuberculosis. We are presenting this case to highlight the unusual solitary nature of the lesion, the absence of any other tuberculous focus in the body, the inconclusive findings of the pre-operative investigations like fine needle aspiration cytology (FNAC), and computed tomography (CT), and the need for histopathology for definitive diagnosis.Item Pulmonary zygomycosis in a diabetic patient.(2006-07-17) Anuradha, K; Lakshmi, V; Umabala, P; Rao, M NWe report a case of pulmonary zygomycosis in an adult male diabetic patient who presented with fever and altered sensorium initially and later developed streaky haemoptysis. Bronchoscopy showed picture of necrotizing pneumonia. Sputum was negative for fungal elements on admission but later bronchial wash and repeat sputum samples were positive by microscopy and culture showed growth of Rhizopus species. Immediately the patient was put on amphotericin B but had a bout of massive haemoptysis and succumbed. A high index of suspicion is needed for an early diagnosis and aggressive treatment of this infection in view of the high mortality rate.Item The role of quantitative cultures of non-bronchoscopic samples in ventilator associated pneumonia.(2006-04-12) Rajasekhar, T; Anuradha, K; Suhasini, T; Lakshmi, VPURPOSE: The objective of this study is to determine the role of quantitative cultures of non-bronchoscopic samples such as blinded bronchial sampling (BBS) and endotracheal aspirates (ETA) in the management of ventilator associated pneumonia (VAP). The study also evaluates the clinical diagnosis of VAP based on the inclusion of Gram stain results of BBS/ETA samples into modified clinical pulmonary infection score (CPIS). METHODS: Fifteen out of the 120 patients admitted to respiratory intensive care unit under mechanical ventilation for more than 48 hours with a clinical suspicion of VAP, were included in this study. Quantitative cultures of BBS and ETA were performed from all the 15 patients. RESULTS: VAP was confirmed in 11 out of 15 cases by quantitative cultures of either the BBS or ETA samples. The condition of 8/11 VAP confirmed patients improved significantly with the change in antibiotic therapy. The overall mortality rate was found to be 18%. The agreement between BBS and ETA results was found to be 83.3%. Modified-clinical pulmonary infection score (CPIS) increased significantly when Gram stain results of BBS/ETA samples were included, thereby strengthening the clinical diagnosis of VAP. CONCLUSIONS: Quantitative culture of lower respiratory tract samples obtained by non-bronchoscopic methods may be a useful alternative to bronchoscopy, in the diagnosis of VAP. Inclusion of Gram stain results of BBS/ETA into modified-CPIS may augment the diagnostic evaluation of VAP.Item Sensitivity pattern of gram negative bacilli to three beta-lactam/beta-lactamase inhibitor combinations using the automated API system.(2007-07-29) Anuradha, K; Sailaja, V V; Umabala, P; Satheesh, T; Lakshmi, VPURPOSE: To evaluate the spectrum of activity of three beta-lactamase inhibitors such as amoxicillin/ clavulanic acid, ticarcillin/ clavulanic acid and piperacillin/ tazobactam in comparison to cephalosporins against gram negative bacilli. METHODS: Gram-negative bacilli isolated from the clinical specimens received in the laboratory were included in the study. Using the API system (bioMiotarieux) during a one-year period, a total of 1,252 Enterobacteriaceae and 385 non-fermenters were evaluated. RESULTS: The percentage resistance of the Enterobacteriaceae isolates was 82.92% to amoxicillin/ clavulanic acid, 58.22% to ticarcillin/clavulanic acid and 22.44% to piperacillin/tazobactam respectively. Pseudomonas aeruginosa showed resistance of 96% to ticarcillin/ clavulanic acid and 61% to piperacillin/ tazobactam and Acinetobacter baumannii showed 49% resistance to ticarcillin/ clavulanic acid and 77% resistance to piperacillin/ tazobactam respectively. The isolates exhibited high resistance to all the generations of cephalosporins and the other groups of antibiotics except carbapenems. CONCLUSIONS: Piperacillin/tazobactam was found to be the most active combination of the three against Enterobacteriaceae and Pseudomonas spp. and ticarcillin/clavulanic acid against Acinetobacter spp. and Stenotrophomonas maltophilia.Item Sporotrichosis in Mysore: a case report to emphasize the role of histopathology.(2008-01-18) Suchitha, S; Vijaya, B; Sunila, R; Anuradha, K; Savitha, RLymphocutaneous sporotrichosis is unusual in southern India. The diagnosis was made by histopathological examination which is purported to have poor sensitivity. The culture of the specimen confirmed the diagnosis. The pre-eminent role of a careful study of serial sections is emphasized.Item Study of lipid profile in hypertensive subjects(2015-10) Anuradha, K; Mathur, Ranjana; Sood, SadhnaAim : The present study was designed to investigate lipid profile in hypertensive subjects.
