Isolation of ckit-positive cardiosphere-forming cells from human atrial biopsy

There is increasing interest in developing cell-based therapies to regenerate functional muscle and blood vessels in infarcted dysfunctional myocardium, using stem cells resident in the adult heart. The objective of our study was to identify an easy and cost-effective method for the isolation and expansion of human adult cardiac-resident stem cells. The cells were isolated from right atrial biopsy samples obtained from patients with ischemic heart disease, who were undergoing coronary artery bypass grafting. Two different isolation methods, enzymatic and nonenzymatic, were employed. The cell yield and cluster formation were not significantly different with either of the techniques used for cell isolation. The nonenzymatic method is recommended because of its simplicity and lower cost compared to the enzymatic method

Repair of Double Orifice Left AV Valve (DOLAVV) with Endocardial Cushion Defect in Adult

Abstract Double orifice left atrioventricular valve (DOLAVV) or double orifice mitral valve (DOMV) is a rare congenital cardiac anomaly manifesting either as an isolated lesion (mitral stenosis or mitral insufficiency) or in association with other congenital cardiac defects. Signs of mitral valve disease are usually present along with the symptoms of associated coexistent congenital heart diseases. Mitral insufficiency due to annular dilatation is seen when DOLAVV is associated with endocardial cushion defects. Surgical intervention like mitral valve repair or replacement is required in 50% of patients and yields good results. We report a case of a 56-year-old lady who successfully underwent surgical correction of DOLAVV with partial atrioventricular canal defect

Covering Ileal Loop without Ostomy: A New Approach to Bring Down the Enterostomy-Related Morbidity

Ileostomy is a commonly performed procedure for colon surgeries and the following emergency small or large bowel resection and anastomosis. We proposed a successful new technique of covering ileal loop without opening it, to decrease the stoma and reversal-related complications

Modified closed chamber sutureless technique for anomalous pulmonary venous connection

Visibility continues to be a major problem during repair of obstructed total anomalous pulmonary venous connection (TAPVC) resulting in frequent use of deep hypothermia and low flow bypass. Sutureless technique for primary repair of anomalous pulmonary venous connection is fast becoming popular. In this described modification of sutureless technique through the lateral approach, the left atrium is marsupialized around the common pulmonary venous chamber, except on the right lateral aspect, providing a bloodless field with minimal retraction of heart facilitating the surgery at mild hypothermia. This technique can be particularly useful in small confluence obstructed TAPVC and in mixed TAPVC

Does transfusion of residual cardiopulmonary bypass circuit blood increase postoperative bleeding? A prospective randomized study in patients undergoing on pump cardiopulmonary bypass

<b>Objective:</b> Homologous blood transfusion after open heart surgery puts a tremendous load on the blood banks. This prospective randomized study evaluates the efficacy of infusing back residual cardiopulmonary bypass (CPB) circuit i.e., pump blood as a means to reduce homologous transfusion after coronary artery bypass surgery (CABG) and whether its use increases postoperative drainage. <b> Materials and Methods:</b> Sixty-seven consecutive patients who underwent elective CABGs under CPB were randomized into 2 groups: (1) cases where residual pump blood was used and (2) controls where residual pump blood was not used. Patients were monitored for hourly drainage on the day of surgery and the 1^st postoperative day and the requirements of homologous blood and its products. Data were matched regarding change in Hemoglobin, Packed Cell Volume and coagulation parameters till 1st postoperative day. All cases were followed up for three years. <b> Results:</b> There was a marginal reduction in bleeding pattern in the early postoperative period in the cases compared to controls. The requirement of homologous blood and its products were also reduced in the cases. <b> Conclusions:</b> The use of CPB circuit blood is safe in the immediate postoperative period. The requirement of homologous blood transfusion can come down if strict transfusion criteria are maintained

Prevalence of psychiatric morbidity among cancer patients – hospital-based, cross-sectional survey

Aim: To study the prevalence of Psychiatric disorders in cancer patients and to find out the factors associated with Psychiatric disorders in Cancer Patients. Settings and Design: Department of Radiotherapy, Medical College, Thiruvananthapuram, cross sectional survey design was used. Methods and Material: Adult patients (18 years of age and above), having a diagnosis of carcinoma were selected by consecutive sampling method.A questionnaire which included back ground data, socio economic variables, treatment variables like type of malignancy, exposure to radiation & chemotherapy prior to the evaluation and current treatment, co occurring medical illness & treatment and past & family history of psychiatric illness was used to collect data. Delirium rating scale and MINI International neuropsychiatric interview were used to assess Psychiatric disorders and delirium. Statistical Analysis Used: Chi square and logistics regression tests were used for analysis. Results: Of the 384 assessed, 160(41.7%) had psychiatric disorders. Adjustment disorders were seen in 22.6%. 10.9% of subjects had major depressive disorder. Thus a total of 33.5% of patients had a diagnosis of either anxiety or depressive disorder. Proportion of patients having delirium was 6.5%. Hypomania was seen in small (1.6%) of patients. Multivariate analysis for various parameters for psychiatric disorders showed that age, past history of chemotherapy, past history of radiotherapy, & surgical treatment of carcinomas are significant predictors of psychiatric disorders. Conclusions: Psychiatric disorders are seen in a significant proportion of Psychiatric patients

Ketamine has no effect on oxygenation indices following elective coronary artery bypass grafting under cardiopulmonary bypass

Cardiopulmonary bypass is known to elicit systemic inflammatory response syndrome and organ dysfunction. This can result in pulmonary dysfunction and deterioration of oxygenation after cardiac surgery and cardiopulmonary bypass. Previous studies have reported varying results on anti-inflammatory strategies and oxygenation after cardiopulmonary bypass. Ketamine administered as a single dose at induction has been shown to reduce the pro-inflammatory serum markers in patients undergoing cardiopulmonary bypass. Therefore we investigated if ketamine can result in better oxygenation in these patients. This was a prospective randomized blinded study. Eighty consecutive adult patients undergoing elective coronary artery bypass grafting under cardiopulmonary bypass were included in the study. Patients were divided into two groups. Patients in ketamine group received 1mg/kg of ketamine intravenously at induction of anesthesia. Control group patients received an equal volume of saline. All patients received standard anesthesia, operative and postoperative care.Paired t test and independent sample t test were used to compare the inter-group and between group oxygenation indices respectively. Oxygenation index and duration of ventilation were analyzed. Deterioration of oxygenation index was noted in both the groups after cardiopulmonary bypass. However, there was no significant difference in the oxygenation index at various time points after cardiopulmonary bypass or the duration of ventilation between the two groups. This study shows that the administered as a single dose at induction does not result in better oxygenation after cardiopulmonary bypass
