Analysis of internal gamma-ray dose to the public from brick as building material in Tamil Nadu, India.

Natural radioactivity due to 238U, 232Th and 40K in brick samples from Tamil Nadu was determined using gamma-ray spectrometry. The mean activity concentrations of 238U, 232Th and 40K, 69 ± 6, 62 ± 6 and 462 ± 23 Bq kg-1, are slightly greater than the world recommended limits of 35, 45 and 420 Bq kg-1, respectively, and they are compared with a similar work carried out across the world. The radiological parameters such as radium equivalent activity, Raeq (193 ± 17 Bq kg-1), internal hazard index, Hin (0.

Quantification of radiological hazards associated with natural radionuclides in soil, granite and charnockite rocks at selected fields in Ekiti State, Nigeria.

Assessment of activity levels of radionuclides that exist in soil, granite, and charnockite rock samples is very crucial because it exhibits an enhanced elemental concentration of uranium (U) and thorium (Th) contributing higher natural background activity than usual in the environment and it may cause health risk to human health through the external and internal exposure. This study determined the radioactivity levels of U, Th, and K radionuclides in soil, granite, and charnockite rock samples collected from selected fields in Ekiti State, Nigeria using Caesium iodide CsI(Tl) scintillation gamma spectrometer. It also evaluated indices of the radiological parameters consisting of radium equivalent activity (Ra), absorbed dose rate (D), annual effective dose equivalent (AEDE), internal hazard index (H), and excess lifetime cancer risk (ELCR).

Determination of internal gamma dose assessment due to natural radioactivity for river sand using a gamma-ray spectrometer.

River sand is an environmental component that is always used as a building material in India and hence the present study, activity concentrations of 226Ra, 232Th and 40K have been measured in sand samples collected from Ponnai river, Tamil Nadu using a high-resolution gamma-ray spectrometer consisting of high-purity germanium detector. Calculated mean specific activity is 31, 84 and 416 Bq kg-1 for 226Ra, 232Th and 40K, respectively. These results reveal that 226Ra was found to be less than the world average value of 33 Bq kg-1 whereas 232Th and 40K were higher than the global mean value of 30 and 400 Bq kg-1, respectively.

ASSESSMENT OF GAMMA DOSE AND ANNUAL EFFECTIVE DOSE RATE FOR COMMONLY USED FERTILIZER SAMPLES IN AGRICULTURE FIELD WITH A STATISTICAL APPROACH.

In this present study, the activity concentration of the naturally occurring radionuclides 238U, 232Th and 40K have been measured in commonly used chemical fertilizers for agriculture by using gamma-ray spectrometry with NaI (TI) detector. Radiological hazard parameters have been calculated for samples. The mean specific activity concentration of the 238U, 232Th and 40K is 176, 5.

Unilateral lower limb oedema: A Hidden Pseudoaneurysm.

Introduction: We present a patient with a rare vascular emergency of mycotic profunda femoris artery pseudoaneurysm presented as an expanding hematoma.

Presentation Of Case: The patient presented with acute onset complaints of severe pain and swelling of the left thigh, mimicking DVT, and was inevitable for limb loss in the absence of timely intervention.

Discussion: The pseudoaneurysm being located in the mid profunda femoris artery was located deep in the intra-muscular plane with adjacent hematoma precluding an open surgical approach.

Acute type A dissection, coarctation of aorta, and levoatriocardinal vein-A rare combination.

Concomitant presence of acute type A dissection, coarctation of aorta and levoatriocardinal vein has not been described. We here present a case of aortic anuerysm complicated by type A dissection with coarctation of aorta and levoatriocardinal vein.

Midterm outcome of off-pump CABG for severe LV dysfunction-Does LV size and function predict their midterm outcome?

Background: The superiority of surgical revascularization in ischemic cardiomyopathy is established beyond doubt, and off-pump CABG (OP-CABG) is a safe way of revascularization in this high-risk subset. Data on the effect of postoperative ventricular function and size on their midterm outcome is scarce.

Materials And Methods: A retrospective study was done on 211 consecutive patients with severe LV dysfunction who underwent OP-CABG from January 2017 to December 2018.

A rare constellation of eventration of right diaphragm, severe right lung hypoplasia, and LPA sling.

Left pulmonary artery sling (LPAS) is a rare congenital cardiac anomaly and is commonly associated with complete tracheal rings and various degrees of tracheobronchial compression. We present a very rare association of LPAS and congenital eventration of right hemidiaphragm in this case report.

Re-exploration after off-pump coronary artery bypass grafting: Incidence, risk factors, and impact of timing.

Objective: Re-exploration after cardiac surgery still remains a troublesome complication. There is still a scarcity of data about the effect of re-exploration after off-pump coronary artery bypass grafting (OPCABG). We here represent our experience on re-exploration following OPCABG.

Large sub-mitral aneurysm compressing the left circumflex coronary artery presenting with atypical chest pain - Rare presentation.

Sub-mitral aneurysm (SMA) is a rare cardiac malformation commonly reported in young adults of African ancestry. SMA is considered a congenital disease caused by developmental defect due to weakness at the atrioventricular junction near the posterior mitral annulus. In the past two decades, a considerable number of cases regarding this rare disease have been reported in Asians, highlighting the importance of considering SMA in differential diagnosis of young patients presenting with mitral regurgitation and chest pain.

Repairing the rheumatic mitral valve in the young: The horizon revisited.

Objective: Most of the rheumatic mitral valve repair literature focuses on older patients with burnt out disease. We present our midterm results of rheumatic mitral valve repair in young patients.

Methods: In this retrospective-prospective study, 106 consecutive children (<18 years) underwent mitral valve repair for rheumatic etiology (2013-2017).

Damus-Kaye-Stansel: Valuable Option for Retraining of Left Ventricle in Late Arterial Switch for Transposition of the Great Arteries.

Management of dextro-transposition of the great arteries with intact interventricular septum along with regression of the left ventricle remains a challenge. Atrial switch always raises concerns about the fate of the right ventricle as a systemic ventricle in the long run. A two-stage repair with pulmonary artery banding and a modified Blalock-Taussig shunt or a single-stage arterial switch with mechanical support has a higher mortality and morbidity.

Effect of Red Blood Cell Storage Duration on Outcome After Paediatric Cardiac Surgery: A Prospective Observational Study.

Background: Retrospective reviews have found the use of stored packed red blood cells (PRBCs) in priming to be associated with increased risk of postoperative complications. The purpose of study was to prospectively investigate the influence of duration of storage of PRBCs used in priming the cardiopulmonary bypass (CPB) circuit on the metabolic profile of the patients, and postoperative outcome after paediatric cardiac surgery.

Methods: Between January 2015 and December 2015, 198 consecutive children operated for cardiac surgery using CPB and received blood for priming the circuit were included.

OPCABG for Moderate CIMR in Elderly Patients: a Superior Option?

Objective: To compare the early and late outcomes of off-pump coronary artery bypass grafting and coronary artery bypass graft + mitral valve repair in elderly patients with moderate chronic ischemic mitral regurgitation.

Methods: One hundred and fifty elderly (age > 70 years) patients with moderate chronic ischemic mitral regurgitation who underwent off-pump coronary artery bypass grafting (n=95) or coronary artery bypass graft + mitral valve repair (n=55) between January 2007 and December 2014 were studied. They were subdivided according to presence or absence of high operative risk.

Dumb-bell in the heart: rare case of biatrial myxoma with mitral regurgitation.

Cardiac myxomas are rare intracardiac tumors, and the majority are benign myxomas involving the left atrium. We report a case of the very rare occurrence of biatrial myxoma associated with mitral regurgitation, which was successfully treated.
