Objective: This case report aimed to highlight intersections of TB and Cardiovasular diseases which carry high morbidity and mortality rates. methods: We are reporting the surgical management of forty seven years female who had back ground history of IDDm (Insulin dependent diabetic mellitus), eSRD (end stage renal disease) on HD (haemodialysis) also she had left subclavian artery stenosis, and paroxysmal atrial fibrillation. She was diagnosed with mitral valve infective endocarditis and found accidently to have an open pulmonary tuberculosis (TB) on the day before surgery. Results: She was started on first line anti-TB treatment. She was isolated in her private room and airborne precautions measures applied. The patient underwent a tissue mitral Valve replacement and tricuspid valve repair annuloplasty. Special precautions were applied in Theatre and on cardiopulmonary bypass machine guided by KAmC-J disinfection protocol. The patient made good recovery postoperatively. She was discharged well on day 7 post operatively. Conclusion: Intersections of TB and cardiovasular diseases carry high morbidity and mortality rates. early diagnosis and early anti tuberculosis treatment can surely improve the patient prognosis. Our decontamination and disinfective procedures are recommended. Cases like this should be monitored long term for the development of further cardiovascular complication.

Purpose:To quantify differences in nonlinear aspects of performance on a seated visual-motor tracking task between clinically asymptomatic males and females with and without a self-reported mild traumatic brain injury ***:Seventy-three individuals with a self-reported concussion history(age:21.40±2.25 years,mean±SD)and 75 without completed the visual-motor tracking task(age:21.50±2.00 years).Participants pressed an index finger against a force sensor,tracing a line across a computer screen(visual-motor tracking).The produced signal's root-mean-square error(RmSe),sample entropy(Sampen,a measure of regularity),and average power(AvP)between 0 and 12 Hz were ***:males with a history of 0 or 1 concussion had greater RmSe(worse performance)than females with 0(pemales with 2+concussions exhibited lower Sampen than females with no history(p=0.001)or a history of 1 concussion(p=0.026).Finally,females with 2+concussions had lower 8-12 Hz AvP than males with 2+concussions(p=0.031).Few differences were observed in the male ***:Females with a self-reported history of multiple concussions exhibited lower Sampen in the visual-motor tracking-task force output structure as compared to those with no reported history of concussion and their male *** Sampen and lower power between 8 and12 Hz indicated persistent impairment in visual processing and feed-forward or predictive motor control systems.

This paper deals with the determination of the thermo-elastic displacements and stresses in a multi-layered body set up in different layers of different thickness having different elastic properties due to the application of heat and a concentrated load in the uppermost surface of the medium. each layer is assumed to be made of homogeneous and isotropic elastic material. The relevant displacement components for each layer are taken to be axisymmetric about a line, which is perpendicular to the plane surfaces of all layers. The stress function for each layer, therefore, satisfies a single equation in absence of any body forces. The equation is then solved by integral transform technique. Analytical expressions for thermo-elastic displacements and stresses in the underlying mass and the corresponding numerical codes are constructed for any number of layers. However, the numerical comparison is made for three and four layers.
