Item ANCA-negative limited Wegener's granulomatosis.(2004-03-24) Ghosh, A; Bandyopadhyay, D; Basu, S; Majumdar, A; Dutta, SA 26-year-old man presented with epistaxis, nasal obstruction and a subcutaneous swelling over the left malar region with radiological evidence of a mass in the right nasal cavity. Histology of the lesions showed necrotizing granuloma with evidence of vasculitis. There was no other systemic involvement and the patient was ANCA-negative. Excellent response to systemic steroid and cyclophosphamide therapy was noted.Item Anomalous Origin of Left Coronary Artery from Pulmonary Trunk in an Adult Patient –A Rare Occurrence.(2008) Chowdhury, A W; Muttalib, M A; Baqui, M A; Dutta, S; Alam, M M; Shakawatullah, M; Mondol, D K; Islam, S S; Shahidullah, M S; Kamal, A H MAnomalous origin of coronary arteries is a rare cause of cardiac disease. One of the very rare coronary anomalies is origin of left main coronary artery from pulmonary trunk. Most of these patients die in the first year of life and only 10-15% survive in adulthood. We are reporting a rare case of anomalous origin of left coronary artery from pulmonary artery who survives into sixth decade of life.Item Application of serum opacity factor in subtyping of group A streptococci & identification of new M-types.(1991-07-01) Prakash, K; Dutta, SOut of 742 isolates of group A streptococci (GAS), 34.0 per cent were positive for production of serum opacity factor (SOF). The T and M typability of these GAS strains was 93.3 and 10.8 per cent respectively. Clustering of the strains under the T patterns 5/12/27, 8/25/Imp. 19 and 3/13/B3264 and low M typability indicated the utility of SOF testing as an additional marker in epidemiological characterisation of GAS. SOF was further found to be useful in identification of new M type and simplified M typing by saving time, labour and sera.Item Assessing burden and its determinants in caregivers of chronic kidney disease patients undergoing haemodialysis(Academy Publisher, 2021-12) Joseph, SJ; Bhandari, SS; Dutta, S; Khatri, D; Upadhyay, A.Background: Caregivers face a lot of adversities while supporting their near ones undergoing haemodialysis, and their burden is often ignored by health professionals. The paucity of research in the Indian context has kept their needs out of sight. Aim: To explore the level of burden in the caregivers of patients with chronic kidney disease (CKD) undergoing haemodialysis and to assess whether patient related variable affects the burden. Methods: Fifty-one patients and their caregivers from two dialysis units in Sikkim, India, were assessed cross-sectionally. The Zarit Caregiver Burden Scale (ZCBS) was administered to measure the caregiver burden. The Patient Health Questionnaire-9 (PHQ-9) and the Charlson’s Comorbidity Index (CCI) assessed the patient’s depression and medical comorbidities, respectively. Descriptive analysis was done for the sociodemographic and clinical variables. Chi-square test was used to find the association between the categorical data. Kruskal-Wallis tested the association between categorical and quantitative variables. Results: Mean age of patient was 46.13 (±13.15) years and that of the caregiver was 44.78 (±12.14) years. 68.6% of caregivers had mild to severe levels of caregiver burden. Caregivers who were unemployed and educated till secondary school were more likely to report caregiver burden. Female gender, older caregivers, and caregivers attending patients with a longer history of haemodialysis reported a more severe burden. Conclusion: The level of burden in caregivers of CKD patients is significant and is affected by various factors, which, in turn, also affects patient’s wellbeing. Further research in this area is needed in our country for better management of patients and policymaking.Item Bevacizumab with paclitaxel and carboplatin for locally advanced (Stage IIIB) metastatic adenocarcinoma of lung: A feasibility study from tertiary care center(International Journal of Medical Science and Public Health, 2019-10) Bera, A; Dutta, S; Biswas, L; Sadhya, ABackground: Lung cancer is the most common cancer and leading cause cancer-related death in worldwide and also in India. Around 42% of these patients have adenocarcinoma. Most of these patients presented in locally advanced stage or metastatic disease. There is no significant difference in effectiveness among different chemotherapy regimens with median survival of 8 months only. Hence, additional treatment option including newer monoclonal antibodies is needed to improve tumor control and survival. Vascular endothelial growth factor (VEGF) is critical determinant of tumor angiogenesis, a process that is necessary component of tumor growth, invasion, and metastasis. Bevacizumab (Bev), a humanized monoclonal antibody (IgG1) targeting VEGF, effective in colorectal cancer, renal cell carcinoma, glioblastoma multiforme, and non-small cell lung cancer and approved for clinical use since 2004. Objectives: The aim of our study is feasibility of the combination of Bev with paclitaxel and carboplatin in locally advanced (Stage IIIB) metastatic adenocarcinoma of lung in our institute, N.R.S. Medical College and Hospital, Kolkata. Materials and Methods: Between February 2015 and December 2018, ninety-eight previously untreated patients with locally advanced metastatic (Stages IIIB and IV) adenocarcinoma of lung treated with Bev with paclitaxel and carboplatin. Paclitaxel at a dose of 175 mg/m2, carboplatin at an AUC 6 mg/ml/min, and Bev at a dose of 15 mg/kg given on the 1st day of chemotherapy. Chemotherapy administered every 3 weeks up to 6 cycles with maintenance Bev until disease progression or unacceptable toxicity whichever is earlier. Patients ECOG 2 or more, brain metastasis, squamous cell histology, and hemoptysis were not included in the study. Results: The Median overall survival (OS), progression free survival (PFS) were 9.4 and 5.2 months, respectively. Anemia (19%) and neutropenia (16 %) are most common toxicity. Conclusion: Bev with paclitaxel and carboplatin in selected patients with adenocarcinoma of lung is safe and confers survival benefit with acceptable toxicity.Item Biophysical studies on prostaglandins: molecular electrostatic potential distribution & interfragmental interaction in PGE1 & PGE2.(1982-08-01) Kothekar, V; Dutta, SItem Ceftriaxone therapy in ciprofloxacin treatment failure typhoid fever in children.(2001-06-31) Dutta, P; Mitra, U; Dutta, S; De, A; Chatterjee, M K; Bhattacharya, S KBACKGROUND & OBJECTIVES: The rapid spread of multidrug resistant (MDR) typhoid fever has posed a great challenge for the treatment of these cases the world over. After the emergence of chloramphenicol resistant Salmonella typhi strains, ciprofloxacin has become the drug of choice for the treatment of typhoid fever even in the paediatric age group. This study evaluated the role of ceftriaxone therapy in bacteriologically confirmed MDR typhoid cases who did not respond to 12-14 days of ciprofloxacin therapy. Attempts have also been made to investigate the in vitro susceptibility of isolated S. typhi strains to chloramphenicol, ciprofloxacin and ceftriaxone. METHODS: A total of 140 children, aged 3-10 yr, clinically diagnosed as having typhoid fever, without any clinical response after 12-14 days of ciprofloxacin therapy were screened for S. typhi by blood culture. In the bacteriologically positive children the treatment was changed to intravenous ceftriaxone for 14 days. The isolated strains of S. typhi were tested for in vitro antimicrobial susceptibility. RESULTS: Clinical and bacteriological cure was observed with intravenous ceftriaxone therapy in all the 32 bacteriologically positive patients. All isolated S. typhi strains were uniformly (100%) susceptible to ciprofloxacin and ceftriaxone but 50 per cent of the strains were resistant to chloramphenicol. The MIC values of chloramphenicol, ciprofloxacin and ceftriaxone ranged between 125-500, 0.0625-0.5 and < 0.0625 microgram/ml respectively. INTERPRETATION & CONCLUSION: The study indicates that although the S. typhi strains were susceptible to ciprofloxacin in vitro, the patients did not respond clinically and bacteriologically to ciprofloxacin therapy. Hence, ciprofloxacin may not represent a reliable and useful option for treating MDR typhoid fever; ceftriaxone may be an effective alternative for the treatment of such cases.Item Certain genetic markers in psychotic disorders.(1984-11-01) Dutta, S; Banerjee, A; Sharma, A; Talukder, G; Chowdhury, A NItem Change in tissue thromboplastin content of brain following trauma.(2005-06-13) Pathak, A; Dutta, S; Marwaha, N; Singh, D; Varma, N; Mathuriya, S NBACKGROUND: Tissue thromboplastin (TTP) is an integral membrane protein contributing to coagulopathy after trauma of brain, which is a rich source of TTP. AIMS: A study was undertaken to establish the TTP content of various areas of normal brain and estimate the changes in TTP activity of brain in response to varying degrees of trauma. MATERIALS AND METHODS: Samples from different areas of brain of ten cadavers were used as controls and they were compared with contused brain tissue obtained after surgery in 25 head injury (HI) patients of varying severity. RESULTS: In the study group, the TTP activity of the frontal, parietal, and temporal lobes after HI was significantly raised in contrast to that of the control group. The TTP activity was also significantly higher in the severe HI patients than those having moderate HI. The mode of injury and the time lapse after HI had no significant bearing on the TTP activity. Subjects above 40 years of age demonstrated a higher mean TTP activity after HI, though it was not statistically significant. CONCLUSION: The study provides quantitative data on TTP activity of normal brain and highlights the role of TTP in coagulopathy following HI through its increased activity after HI, more so in the severe HI group.Item Changes in Preterm Human Milk Composition with Particular Reference to Introduction of Mixed Feeding.(2014-12) Dutta, S; Saini, S; Prasad, RObjective: To study the changes in composition of preterm milk till 6 months of age. Methods: Milk samples from 33, 19, 7 and 12 lactating mothers (delivered <34 weeks) were analyzed on days 7, 28, 90 and 180, respectively. Results: Triglyceride and sodium concentrations increased significantly with time and protein concentration decreased significantly over 180 days. Sodium (P=0.02) and triglyceride concentrations (P=0.06) were higher in milk samples of mothers who had introduced mixed feeding by 6 months post natal age (n=6) compared to exclusively breast-feeding mothers (n=6); but lactose and protein content was not significantly different. Conclusions: Milk of preterm mothers has higher amount of triglycerides and sodium during introduction of mixed feeding.Item Cherubism--a case report.(1986-07-01) Reddy, G C; Nalini, K; Gupta, S K; Agrawal, J K; Bajpai, H S; Dutta, S; Hatwal, A; Gupta, AItem Chilaiditi syndrome with ascites.(2002-06-21) Bhattacharya, P C; Bhattacharya, A K; Dutta, S; Mahanta, N; Talukdar, RItem Cleanliness: Success in Water Borne Diseases(Indian Council of Medical Research, 2019-01) Debnath, F; Deb, AK; Sinha, A; Chatterjee, P; Dutta, SItem Clinical, echocardiographic and haemodynamic profile of hypertrophic cardiomyopathy.(1988-03-01) Maity, A K; Chatterjee, S S; Ganguly, K; Chowdhry, S; Dutta, S; Guha, S; Das, M K; Banerjee, A; Kar, C CItem Clinicopathological profile of hepatic involvement in type-2 diabetes mellitus and its significance.(2008-08-05) Banerjee, S; Ghosh, U S; Dutta, SAIMS AND OBJECTIVES: Involvement of liver as an organ complication in Type 2 Diabetes Mellitus (T2DM) is known. Studies are few about their baseline parameters from our country. Study the disease burden and clinicopathological profile of hepatic involvement in T2DM, find the associations with known risk factors and thus try to identify simple markers of advanced disease. MATERIAL AND METHODS: A screened group of randomly selected 47 patients of T2DM without other liver diseases (viral, alcoholic, drug, autoimmune, etc.) was selected. Their clinical (age, sex, body mass index, family history, blood pressure), biochemical (transaminases, lipid profile), and hepatic ultrasonographic (USG) and histopathological (HPE) profiles were studied. Segregation was done according to the histological severity and duration of diabetes (< 5 yrs, 5-10 yrs, > 10 yrs). RESULTS: On histology, normalcy was maintained in 17%, only fatty change was present in 43%, nonalcoholic steatohepatitis (NASH) could be identified in 40% with more advanced disease in 23%. Prevalence of cirrhosis was low. Positive family history, hypertension, longer duration, female sex and increased body mass index were significantly associated with NASH; more advanced disease was associated with male sex only. Incident lipid profile and transaminases levels were non-contributory. In the early stage, USG detected abnormality correlated poorly with HPE. CONCLUSION: The burden of hepatopathy in T2DM is high; with improving cardiovascular mortality, a higher burden awaits us in the next decade or so. Naturally, it becomes imperative to the treating clinician for targeting this aspect of diabetic complication from the very beginning of therapy.Item Community participation in the field of health and nutrition.(1999-01-13) Dutta, SItem Comparing Hand-hygiene Measures in a Neonatal ICU: A Randomized Cross-over Trial.(2013-10) Sharma, V S; Dutta, S; Taneja, N; Narang, AItem Comparison between two different modes of oxygen therapy during immediate postoperative period following mitral commisurotomy.(1998-10-04) Mitra, D; Ray, M; Dutta, S; Sarkar, A; Rudra, AHypoxaemia is a common postoperative problem after thoracotomy. Oxygen therapy with continuous monitoring by pulse oximetry should be a routine practice. This study was conducted to compare the efficacy between nasal cannula and ventimask for post-thoracotomy oxygen supplementation on 20 patients divided into 2 groups of 10 each undergoing closed mitral commisurotomy. The study period was of 5 months duration from March to July, 1996. The mean oxygen saturation remained above 98% in both the groups receiving oxygen either by nasal cannula or ventimask. As there was adequate oxygenation, the cost benefit ratio favours the use of nasal cannula for routine postoperative oxygen supplementation in the closed mitral commisurotomy patients.Item Concurrent chemoradiation with paclitaxel in locally advanced head and neck cancer: A feasibility study from tertiary cancer care center(International Journal of Medical Science and Public Health, 2019-11) Bera, A; Banerjee, C; Dutta, S; Biswas, LBackground: In India, the majority of the head and neck squamous cell carcinoma (SCC) of head and neck (60–80%) presented in locally or locoregionally advanced stage but non-metastatic disease as compared to 40% in developed nations. Uncontrolled local and/or locoregional disease causes most fatalities and predominant failure pattern is local and/or locoregional. Concurrent chemoradiation (CRT) is now standard of care. However, regarding either the optimal scheduling of chemotherapy regimen or radiotherapy (RT) dose fractionation scheme, no consensus exists. Paclitaxel is also active agents against squamous cell carcinoma of head and neck. Weekly paclitaxel appeared to be equivalent to weekly cisplatin with concurrent radiation in the treatment of locally advanced SCC of head and neck cancer (HNC). Concurrent chemoradiotherapy with paclitaxel in locally advanced head and neck malignancy is recommended in NCCN Guideline. Objectives: The aim of our study is feasibility and efficacy of CRT with paclitaxel for the treatment locally advanced HNC in our institute, Nil Ratan Sircar Medical College and Hospital, Kolkata. Material and Methods: Between January 2014 and December 2018 ninety eight (98) previously untreated patients with locally advanced histologically confirmed carcinoma oral cavity, oropharynx, and hypopharynx treated with CRT. Chemotherapy consisted of paclitaxel at a dose 40 mg/m2 over 1 h given once weekly from 1st week of RT, up to 4–6 cycles. RT consisted of 66 Gy/33#/61/2 weeks, 2 Gy/fraction, delivered by two parallel opposed lateral face and neck and low anterior neck portal, in cobalt 60 machines. Toxicity was graded using Common Terminology Criteria for Adverse Events v3. To assess response to therapy contrast-enhanced computed tomography (CECT) head and neck and/or magnetic resonance imaging head and neck; CECT chest or whole-body fluorodeoxyglucose and positron emission tomography computed tomography scan were done. Results: Overall complete response (CR) rate seen in 68% and partial response seen in 32% patients. Two-year disease-free survival, progression free survival, and overall survival were 59%, 72% and 85%, respectively. Grade II acute skin reaction seen in 45% patients and Grade III acute skin reaction seen in 55% patients. Similarly, Grades II and III mucosal reaction is seen in 48% and 52% patients. All patients experience Grade II dysphagia and managed conservatively. Conclusions: CRT with paclitaxel in locally advanced HNC is safe and confers high CR rate with acceptable toxicity. However, more randomized study with large number of patients is needed to come to conclusions regarding its efficacy.Item Concurrent chemoradiotherapy for muscle-invasive bladder carcinoma for organ preservation: A feasibility study from tertiary care center(International Journal of Medical Science and Public Health, 2019-10) Bera, A; Dutta, SBackground: The primary goal of treatment in oncology is cure but efforts should be made to preserve quality of life. The gold standard for treatment of muscle-invasive bladder cancer is radical cystectomy. However, radical cystectomy cannot be performed without risk of complications and often the outcome for the patient is a mediocre quality of life as the patient has to live with an artificial bladder or ileal conduit. Even after radical cystectomy, 40–50% of patients will succumb to distant metastases within 5 years. As in the case of several other malignancies, increasing efforts have been made over the last few decades to adopt organ sparing treatment. Bladder-sparing monotherapies lead to disappointing results, local disease control may be maximized using a trimodal approach based on complete transurethral tumor resection of bladder (TURB), followed by concurrent chemoradiotherapy and cisplatin-based systemic chemotherapy. Objectives: The aim of our study is feasibility of concurrent cisplatin with radiation in bladder preservation in our hospital. Materials and Methods: Thirty-two previously untreated patients of histologically proven transitional cell carcinoma of urinary bladder received concurrent chemoradiation (60 Gy) with cisplatin. All patients received concurrent chemotherapy with cisplatin infusion in a dose of 20 mg/m2/day on consecutive 5 days from Day 1 to Day 5 in 1st and 5th week of radiotherapy. Detailed clinical examination along with cystoscopy, TURB along with biopsy, and computed tomography scan of abdomen pelvis were done before treatment and to assess response toxicity, and disease-free survival (DFS) during follow-up period. Results: Median follows up period was 36 months. Local disease control was seen in 71% patients. Five years DFS is 58%. Five years overall survival is 64%. Conclusions: Concurrent chemoradiation in carcinoma of urinary bladder is feasible in our hospital and results in good local control, survival with acceptable toxicity.
