Abstract
Many lesions that occur in the jaw have a similar radiographical appearance and it is often difficult to differentiate among them. Despite development of various cross-sectional imaging modalities, the radiograph still remains the first and the most important investigation. Radiographical evaluation of jaw lesion characteristics, which include location, margin, density, relation to tooth, along with knowledge of the clinical data, generally helps in narrowing the differential diagnosis.

Abstract
Electromagnetic transition probabilities have been measured for the intraband and interband transitions in the two sequences in the nucleus (135)Nd that were previously identified as a composite chiral pair of rotational bands. The chiral character of the bands is affirmed and it is shown that their behavior is associated with a transition from a vibrational into a static chiral regime.

Abstract
A cross sectional study was done to ascertain the current knowledge among physicians and optometrists regarding diabetic retinopathy in a district of West Bengal. We obtained response from 242 physicians and 36 optometrists working in government health units. The questionnaire comprised of three sections covering magnitude of problem, risk factors and management. The responses were analysed and graded. In different sections, knowledge of 74 - 78% physicians and 83 - 86% optometrists was graded as not acceptable. Existing lack of knowledge among physicians and optometrists regarding diabetic retinopathy needs correction.

Abstract
BACKGROUND & OBJECTIVE High resolution computed tomography (HRCT) scans are known to be helpful in early diagnosis and management of patients with miliary tuberculosis (MTB). We made an attempt in this study to identify patterns of pulmonary MTB on HRCT and to correlate the HRCT disease extent with pulmonary function tests (PFT) and gas exchange analysis (GEA). METHODS A total of 16 non-HIV patients with MTB underwent HRCT of the chest, PFT and GEA. All the investigations in these patients were completed within 20 days of presentation. Evidence of TB was diagnosed by biopsy from lymph nodes (3/16), organ biopsy [skin, liver, bone marrow and lung (transbronchial) (6/16)]. In one patient fundoscopy revealed choroid tubercles. In 6 patients, diagnosis was confirmed by clinical/radiological improvement following anti-tuberculosis therapy. Radiological patterns of involvement on HRCT of the lungs were studied and disease extent was estimated in each case by consensus between two radiologists using specially devised visual scoring system. Disease extent was correlated with PFT and GEA. Spearman rank correlation was used for statistical analysis. RESULTS Findings on HRCT in MTB included miliary nodularity (16/16), alveolar lesions such as ground glass attenuation and/or consolidation (5/16), lymphadenopathy (8/16), peribronchovascular interstitial thickening (1/16), emphysema (1/16), pleural pathology (2/16), and pericardial effusion (2/16). A significant correlation was noted between disease extent score and forced vital capacity (FVC) (r = -0.76; P=0.003), forced expiratory volume in one second (FEV(1))(r = -0.74; P = 0.005), total lung capacity (TLC) (r = -0.66; P = 0.037), oxygen saturation in arterial blood (SaO(2)) (r = -0.69, P = 0.01), diffusion capacity of the lung (DLco) (r = -0.8; P = 0.02). INTERPRETATION & CONCLUSION Our findings showed that HRCT reliably diagnosed MTB, and thus could help in predicting derangement of pulmonary function tests and GEA in these patients.

Abstract
20015 Background: Acute Lymphatic Leukemia in children is a curable disease in the range of 80–90 % in developed Countries by aggressive protocol like BFM, St. Judes’. In developing Countries like ours, patients can’t tolerate those aggressive protocol because of Socio- economic and nutritional factors. The less aggressive Protocol like INCTR (International Network for Cancer Treatment & Research) are suitable in developing Countries like ours. The aim of our study was to see outcome of childhood ALL patient with INCTR protocol and tolerability of the protocol in Indian-asian population. Methods: We treated 480 Children (age range 1–25 years, median age of 11 yrs) with INCTR Protocol at Netaji Subhash Chandra Bose Cancer Research Institute, Kolkata, India, a tertiary cancer centre from Eastern India during period from April ’99 to Dec ’06. There was female preponderance in the study. Fever 283 (58.9%), lymphadenopathy 211 (43.9%) and haepatosplenomegaly 153 (31.8%) were the major clinical presentation. Forty-three (8.9%) patients were present with hyper Leukocytosis. C-ALL phenotype were the largest group though the incidence of the T-ALL were quite high (27.9%). Results: Remission induction were seen in 446 (92.9%) of the patient. In a follow-up period of 88 months (with an average of 54 months) the disease-free survival ( DFS) was 66.8% (321 patients) with an overall survival of 73.9% (355 patients). The isolated bone marrow relapse was seen in majority of the cases 40 (8.33%) and the major relapse was in maintenance and first 6 months of completion of therapy. The major cause of morbidity was infection 316 (65.8%) followed metabolic complications 81 (16.8%), hemorrhage 52 (10.8%), neurologic 10 (2.08%), hepatitis 6 (1.25%) and pancreatitis 5 (1.04%). The major cause of the mortality was infection 75%(360 patients) followed progressive disease 7.91% (38 patients) and Hemorrhage 5.83%( 28 patients). Conclusions: The data of acute lymphatic leukemia from a developing country is encouraging. The protocol was well tolerated by India- asian population. No significant financial relationships to disclose.

Abstract
15166 Background: Adenocarcinoma of the gall bladder accounts for approximately 4% of all malignant neoplasm of the gastro- intestinal tract. Though surgical resection is the treatment of choice, majority of the cases are unresectable. Different chemotherapeutic agents including 5Flurouracil, Mytomycin C, Cisplatin, Methotrexate, Etoposide and Doxorubicin have been tried single or in combination. Partial response lasting from weeks to several months have been observed only in about 10% - 20 % of the cases and the median survival for patients with gall bladder cancer is approximately 4 months. Gemcitabine has shown strong anti tumour activity in a variety of solid tumours. Cisplatin has synergistic activity with Gemcitabine. The aim of our study was to determine the response rate of Gemcitabine and Cisplatin combination in unresectable gall bladder cancer and to see the tolerability in Indian-Asian pollution. Methods: During period from November 2002 to December 2006 we selected 84 consecutive patients with histologicaly proven unresectable measurable, gall bladder cancer. The inclusion criteria were performance status more than 60% (Kornofsky) and normal liver (bilirubin < 2) and kidney function ( creatinine <2) function . All patient received Gemcitabine (1000mg/m2 intravenously over 30 minute) on day 1 and day 8 and Cisplatin total (100mg/m2 divided D1 to D3) every 21days. Response assessment was done by CT Scan after 3 cycles of chemotherapy. All 84 patients are eligible for efficacy and toxicity analysis. Results: There were 15 (17.8%) complete responders, 27 (32%) partial responders, 22 (26.1%) with stable disease and 20 (23.8%) shows disease progression. The median time to progression was 22 weeks (range 12- 30 weeks). The median duration of response was 16 weeks (range 5.6 - 60 weeks). The median over all survival was 24 weeks (range 11–32 weeks) with 1year survival rate of 20.2%. WHO grade III or IV anaemia was seen in 23 (18.63%) patients respectively. Sixteen (13.44%) patients experienced grade III or IV neutropenia while grade III or IV thompocytopenia was seen in 8 patients (6.72%). Conclusions: The present study showed the Gemcitabin & Cisplatine combination was very useful in advanced unresectable gall bladder cancer. It was well tolerated by the patients. No significant financial relationships to disclose.

Abstract
7057 Background: Almost 60% of the patients with Acute Myeloid Leukemia (AML) are over the age of 60 years. Age is one of the strongest adverse prognostic factor for AML, both for induction remission and for survival. Studies have shown that elderly patients have reduced tolerance to aggressive chemotherapy especially the myelosupressive effects. Elderly patients with Leukemia who receive intensive treatment often die as a result of chemotherapy. Aggressive chemotherapy is also costly which the relatives in developing country are reluctant to spend for the elderly patients. The aim of our study was to see the outcome, tolerability and cost effectiveness of oral chemotherapeutic agents. Methods: We selected consecutive 100 patients more than 50 years of age in haemato oncology department of NCRI (Netaji Subhas Chandra Bose Cancer Research Institute) during the period from Jan 2004 to Dec 2006. The mean age of the patients was 65 (range 50 –71) years. There was male preponderance. The inclusion criteria were performance status more than 60% (Kornofsky), Morphological, Cyto-Chemical and Immunophenotyping diagnosis of Acute Myeloid Leukemia (AML), normal liver (billirubine < 2) and kidney function ( Creatinine <2%). After the incent consent all patient were started oral chemotherapeutic agents 6 Mercptopurine (6MP) 75mg/m2. Etoposide 70mg/m2 and Prednisolone 40mg/m2. All agents are given 3 weeks followed by 7 days gap every month and continued for 6 months. Bone Marrow was repeated after 3rd & 6th course of chemotherapy. Results: Fifteen (15%) and thirtyeight patients (38%) had complete hematological response after 3rd & 6th course of chemotherapy. Seven patients (7%) died because of grade III/IV Neutropenia. Median duration of Myelosupression was 18 days (2 to 48 days).12% required hospitalisation. With median follow up of 19 months (range 2–36 months) the disease free survival (DFS) and over all survival (OS) was 18 % and 32 % respectively. Conclusions: The combination of oral chemotherapeutic agents consisting of 6MP, Etoposide & Prednisolone were well tolerated by elderly patients with good induction remission, low mortality and median survival. It was cheaper and well accepted by the patients. No significant financial relationships to disclose.

Abstract
Human papillomavirus (HPV) DNA in cervical scrape samples of married women from Manipur (n= 692) and Sikkim (n= 415) in northeast India was determined and compared with that of women from West Bengal (n= 1112) in eastern India by polymerase chain reaction. HPV prevalence was lower in Manipur (7.4%) than in Sikkim (12.5%), which was closely followed by West Bengal (12.9%). HPV18 was predominant in Manipur (2.03%) and strikingly lower (0.2%) in Sikkim and West Bengal (0.9%), while the reverse was true for HPV16. The proportion of HPV16/18 infections in Manipur (3.3%, 22/672) and Sikkim (3.89%, 14/359) were comparable and significantly lower compared to that in West Bengal (7.8%, 79/1007) among women having normal cervical cytology. Such prevalence was similar among all age groups in Manipur: increased with age for women in Sikkim and dropped with age for those in West Bengal similar to that reported previously. At age < or =30 years, HPV16/18 prevalence in Manipur (3.3%) and Sikkim (2.5%) was comparable but was significantly lower (P < 0.05) in contrast to that in West Bengal (8.8%). Among abnormal cytologic lesions, HPV16/18 infections were significantly higher than in normals (P= 0.000) both in Sikkim (14.3%) and West Bengal (20.9%) and absent in Manipur. Such prevalence was noted among women in Sikkim aged >30 years and equally among those in West Bengal aged < or =30 or >30 years. Thus, women from northeast India, particularly from Manipur, appear less susceptible to HPV16/18 infection and related cervical lesions compared to those from West Bengal, where such proneness was prominently evident at age < or =30 years.

Abstract
The peroxisome proliferator-activated receptor gamma (PPARgamma) regulates inflammation and may play a role in asthma. Using mouthwash-derived DNA and clinical interviews and measurements, we investigated the association of previously characterized single-nucleotide polymorphisms in the PPARG gene (Pro12Ala, C1431T, and C-681G) with asthma exacerbations in patients aged 3-22 years (n=569). The common homozygous haplotype combination of the Pro12 and C1431 alleles was associated with increased risk for asthma exacerbations (ProC, odds ratio (OR) 1.87, 95% confidence interval 1.25-2.79; P=0.002). The ProC genotype was associated with increased school absences (OR 1.82, 95% confidence interval 1.21-2.76; P=0.004) and hospital admissions (OR 2.32, 95% confidence interval 1.18-4.58; P=0.015) over the preceding 6 months. The population-attributable risk of this genotype was 33%. Common genetic variation at the PPARG locus may play an important role in modulating the long-term control of asthma in children and young adults.

Abstract
The objective of this prospective observational clinical study is to derive and validate a diagnostic model for prediction of obstructive sleep apnea (OSA) in subjects presenting with non-sleep-related complaints in a tertiary care center in north India. We included 102 subjects (group I, range 31-70 years) presenting to the hospital with non-sleep-related complaints. None of the subjects had any significant comorbid illness such as respiratory or congestive cardiac failure. All subjects underwent detailed evaluation including polysomnography (PSG). Various parameters were compared between the cases (apnea-hypopnea index, AHI > or =15/h) and controls (AHI <15/h). Using multivariate logistic regression analysis, a diagnostic model for prediction of OSA was derived. Subsequently, using similar selection criteria, 104 subjects (group II, range 32-68 years) were included for validation of the newly derived diagnostic model. Body mass index [BMI; OR (95% CI), 1.14(1.1-1.2)], male gender 5.0(1.4-27.1), relative-reported snoring index (SI) 2.8(1.7-5.0), and choking index (ChI) 8.1(1.4-46.5) were significant, independent predictors of OSA. Diagnostic model was computed as score = [1.61 x (gender)] + [1.01 x (S1)] + [2.09 x (ChI)] + [0.1 x (BMI)] where, gender: 0 = female, 1 = male and SI, ChI, BMI are actual values. The diagnostic model had an area under the receiver operator characteristics curve of 89.6%. A cutoff of 4.3 for the score was associated with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 91.3, 68.5, 70.5, and 92.3%, respectively. Misclassification rate with the application of the diagnostic model on group II subjects was 13.5% (14/104). Sensitivity, specificity, PPV, and NPV of the model for predicting OSA in this group were 82, 90.7, 89.1, and 84.5%, respectively. BMI, male gender, SI, and ChI are independent predictors of OSA. Diagnostic model derived from these parameters is useful for predicting presence of OSA and screening subjects for PSG.

Abstract
BACKGROUND The homozygous presence of the arginine-16 variant of the beta(2) adrenoceptor gene ADRB2 reverses the benefits from the regular use of short acting beta(2) agonists in asthmatic adults compared with the homozygous glycine-16 genotype. We studied the effect of this polymorphic variation on asthma exacerbations in children and young adults and its relation to long acting beta(2) agonists. METHODS A cross-sectional survey was undertaken using electronic records, direct interviews, and genotype determination of position 16 and 27 of the ADRB2 gene in DNA from mouthwash samples of 546 children and young asthmatics attending paediatric and young adult asthma clinics in Tayside, Scotland during 2004-5. The primary outcome measure was asthma exacerbations over the previous 6 months. RESULTS There was an increased hazard of asthma exacerbations across all treatment steps of the British Thoracic Society (BTS) asthma guidelines when the homozygous genotypes Arg/Arg and Gly/Gly were compared (OR 2.05, 95% CI 1.19 to 3.53, p = 0.010), particularly in patients treated with salmeterol (OR 3.40, 95% CI 1.19 to 9.40, p = 0.022). The Glu27Gln polymorphism had no significant effect on asthma exacerbations in any treatment group. CONCLUSIONS The arginine-16 genotype of ADRB2 predisposes to exacerbations in asthmatic children and young adults, particularly in those exposed to regular salmeterol. This may be explained by genotype selective salmeterol induced downregulation and impaired receptor coupling, and associated subsensitivity of the response.
