Abstract
Background: The diagnosis and management of acute coronary syndrome (ACS) have improved significantly over the past few decades; however, the recognition of myocardial ischemia still proves to be a dilemma for cardiologists. The aim of this study was to determine the role of hematological and coagulation parameters in the diagnosis and prognosis of patients with ACS.
Methods: This prospective study recruited 250 patients with ACS and 250 healthy controls. The diagnostic role of hematological and coagulation parameters was assessed by comparing the patients with ACS with the control group. The relationships between these parameters and mortality were determined by dividing the patients into 2 groups: Group A (discharged) and Group B (patients who died within 30 days of follow-up). Multivariate Cox regression analysis was performed to calculate the hazard ratio (HR).
Results: The mean age of the patients was 55.14±10.71 years, and 65.2% of them were male. Prothrombin time (P<0.001), activated partial thromboplastin time (P<0.001), mean platelet volume (MPV) (P<0.001), white blood cell (WBC) count (P<0.001), and red blood cell distribution width (RDW) (P<0.001) were significantly higher in the case group than in the control group. WBC count (P<0.001), RDW (P<0.001), and MPV (P<0.001) were significantly higher in the controls than in the case group. The Cox regression model showed that RDW above 16.55% (HR=6.8), MPV greater than 11.25 fL (HR=2.6), and WBC higher than 10.55×103/μL (HR=6.3) were the independent predictors of mortality.
Conclusion: In addition to being the independent predictors of short-term mortality, RDW, WBC, and MPV when used together with the coagulation profile may aid in the diagnosis of ACS in patients presenting with chest pain.

Abstract
BACKGROUND Although blood urea nitrogen (BUN), creatinine (Cr) and electrolytes are not the mainstay of diagnosis in acute coronary syndrome (ACS) patients but they may have a role in providing a more detailed view of the complications and mortality rates. The aim of this study was to determine the efficacy of these parameters in the diagnosis and mortality risk-assessment of patients with ACS. METHODOLOGY A total of 200 patients with ACS were recruited in this prospective study. The relationship of serum BUN, Cr and electrolytes with cardiac enzymes, Global Registry of Acute Coronary Events (GRACE) and mortality was assessed during a 6-months follow-up. Statistical test like multivariate linear regression and binary logistic regression analysis were applied. RESULTS On multivariate linear regression analysis, serum potassium (K) (Unstandardized Coefficient B=-3.77; p=0.04) showed significant negative association with Creatine Kinease and serum BUN (Unstandardized Coefficient B=0.52; p=0.001) showed significant positive association with Troponin I. The patients with GRACE>105 had significantly higher levels of serum BUN and Cr. Receiver operating characteristic curves showed that area under curve (AUC) of BUN (0.7) was higher than AUC of Cr (0.5). Multiple adjusted model showed that patients with BUN>32.5mg/dl were almost 20 times more likely to be associated with mortality as compared to reference group. CONCLUSION In addition to cardiac enzymes, K along with BUN and Cr may serve as important aid in diagnosis of ACS. BUN and Cr may also serve as important tools in mortality-risk assessment of ACS patients.

Abstract
BACKGROUND Recent studies have shown that complete blood count (CBC) parameters can effectively predict long-term mortality and re-infarction rates in acute coronary syndrome (ACS). However, the role of these parameters in predicting short term mortality has not been studied extensively. The main objective of this study was to determine whether CBC parameters can predict 30-days mortality and the incidence of major adverse cardiac event (MACE) in ACS patients. METHODOLOGY A total of 297 patients with ACS were recruited in this prospective study. The relationship of baseline white blood cell (WBC) to mean platelet volume ratio (WMR) with MACE and mortality was assessed during a 30-days follow up. The patients were divided into two groups: Group A [WMR<1000] and Group B [WMR>1000]. Multivariate COX regression was performed to calculate hazard ratios (HR). RESULTS WMR had the highest area under receiver operating characteristics curve and highest discriminative ability amongst all CBC parameters in predicting mortality. Patients in Group B had a higher mortality rate (p<0.001) than patients in Group A. WBC count (p=0.02), platelet count (p=0.04), WMR (p=0.008), platelet to lymphocyte ratio (p<0.001) and neutrophil to lymphocyte ratio (p=0.03) were significantly higher in the MACE-positive group as compared to MACE-negative. In multivariate cox regression analysis, WMR>1000 (HR=2.9, 95% confidence interval 1.3-6.5, p=0.01) was found to be strongest biochemical marker in predicting mortality. CONCLUSION WMR is an easily accessible and an inexpensive indicator, which may be used as a prognostic marker in patients with ACS.

Abstract
Lutembacher syndrome is characterized by a congenital ostium secundum atrial septal defect and an acquired mitral valve stenosis. We present a similar case in a 31-year old male who came in with orthopnoea, central cyanosis and pedal oedema. Examination revealed cardiac murmurs in tricuspid and apical regions. Chest x-ray showed signs of pulmonary congestion and ventricular enlargement. Electrocardiogaphy (ECG) revealed right axis deviation and right bundle branch block along with atrial fibrillation and Transthoracic Echocardiography (TTE) showed abnormal valves (mitral stenosis with calcification and tricuspid regurgitation) and dilated cardiac chambers. The patient was consequently treated with beta-blockers and diuretics and scheduled for valvular and septal repair via open heart surgery. The purpose of this case report is to assist cardiologists in diagnosing this syndrome accurately on the basis of symptoms and investigations.

Abstract
Idiopathic Myelofibrosis is a rare myeloproliferative disorder. In children, it becomes even rarer. Herein, we report a case of idiopathic myelofibrosis of a 6-year old male patient who presented with complaints of pallor, petechiae and bleeding from gums. Bone marrow aspirate showed afragmented haemodiluted smears with erythroid and myeloid precursors scattered throughout. Trephine biopsy showed increased background fibrotic activity along with clusters of histiocytes. A diagnosis of paediatric primary myelofibrosis was made on biopsy. The patient also developed a stroke that resulted in left-sided hemiparesis. An MRI suggested an intraparenchymal haemorrhage along with meningeal extramedullary haematopoiesis.

Abstract
Metachromatic leukodystrophy is a rarely occurring neurodegenerative metabolic disorder with an incidence of 1-9 individuals out of 1,000,000. We present a similar case in an eighteen month old child which was extremely challenging to diagnose. Clinical symptoms suggested motor regression and developmental delay which gave rise to suspicion of a neurodegenerative disorder. An MRI scan of the brain revealed cortical demyelination with tigroid appearance which confirmed the diagnosis of Metachromatic leukodystrophy. Due to the lack of availability of a treatment option like bone marrow transplant, the patient could only be given physiotherapy to help with the musculoskeletal manifestations of the disorder. The purpose of this case report is to identify clinical presentation and classical MRI findings to diagnose MLD in absence of enzyme assay and gene mutation analysis.

Abstract
The ultraviolet photochemistry of phenylacetylene was studied in a molecular beam at 193 nm. The only primary photofragments observed were HCCH (acetylene) and C(6)H(4). Some of the C(6)H(4) molecules were found to decompose to 1,3,5-hexatriyne and molecular hydrogen. An enthalpy of formation of DeltaH(f) < or = 160 +/- 4 kcal mol(-1) was determined for 1,3,5-hexatriyne from the energetic threshold for this process. This experimentally determined value agrees well with our ab initio calculations performed at the G2 level of theory. Angular distribution measurements for the HCCH + C(6)H(4) channel yielded an isotropic distribution and were attributed to a long-lived intermediate and ground-state dissociation. An exhaustive search yielded no evidence for the phenyl + ethynyl or the atomic hydrogen elimination channels even though these were observed in the pyrolytic studies of phenylacetylene [Hofmann, J.; Zimmermann, G.; Guthier, K.; Hebgen, P.; Homann, K. H. Liebigs Ann. 1995, 631, 1995. Guthier, K.; Hebgen, P.; Hofmann, K. H.; Zimmermann, G. Liebigs Ann. 1995, 637, 1995].

Abstract
The association of aetiological agents incriminated for bladder cancer are well recognised. They are divided into two groups, occupational and non-occupational. The commonest occupational agents are 2-naphthylamine, benzidine, aminobiphenyl, dichlorobenzidine, orthodianisidine and orthotolidine. Recognised non-occupational agents include tobacco, recurrent chronic bladder infection/infestation, coffee and drugs. This study was conducted to evaluate these factors in patients with bladder cancer in our population. Of 250 cases studied, 203 were males and 47 females with a male to female ratio of 4.3:1. In 13.6% cases occupational factors were established with an average duration of exposure of 12 years. Majority (68%) of patients had smoking as the predominant non-occupational factor. In this group average cigarettes smoked per day was 23 with a range of 15 to 90. The duration of smoking ranged between 5 to 55 years with an average of 26 years. Sixty patients (24%) were neither smokers nor had any associated high risk occupation.

Abstract
Keeping in view our socio cultural millieu, the psychological aspects of twenty renal transplants recipients and equal number of patients on dialysis were studied. Socio psychiatric profile in the dialysis and transplanted patients revealed that the frequency of anxiety, depression and hypochondriasis was significantly less (P less than 0.01) in the transplanted group. On Bender Gestalt Scale the transplanted group achieved normal status in significantly higher (P less than 0.05) number compared to the dialysis patients. It was concluded that transplanted patients showed marked improvement in social functioning, psychological symptoms and enduring personality traits compared to patients on maintenance dialysis.
