ABSTRACT
Background: Reaction time a pshychomotor test is widelyused in cognitive neuroscience. cognitive functions of humanbrain includes eg. attention, perception, memory, intelligencyetc., all these affect the academics performance, learning,mental processing and motor performance. Reaction time asimple test can measures the time of mental informationprocessing and motor response to it .The mental processingtime is a main factor to affect the academics performance.Aim: To find the relation between audio-visual reaction timeand academic performance for assessing the cognitive statusof first year medical students.Materials and Methods: A cross-sectional study wasconducted in the Department of Physiology, RUHS College ofMedical Sciences, Jaipur from January 2018 to March 2018. Atotal of 64 first year MBBS healthy medical students of agegroup 18-20 years were enrolled in this study (males-36,females-28). The test was performed on Audio Visual ReactionTime (AVRT) machine of Medisystems by pressing the switchas soon as she/he saw the light for VRT or heard the sound forART. Measurement of academic performance was assessedby their performance in the first MBBS university exam.Students with a history of hearing or visual disorder wereexcluded from the study. The Reaction time for both visual andauditory and academic performance was compared betweenthe two groups and correlated the audio-visual reaction timewith the academic performance in both male and females.Statistical analysis was performed using SPSS softwareversion 20.Results: The VRT is (0.71ms) faster than ART (1.63ms). TheRT was not significantly difference in males when compared tofemales and academic performance was significantly more infemales 393.11±40.93 compared to male 368.56±28.87 withp=0.003 and there was a non-significant, weak negativecorrelation of the RT with the academic performance with VRT(r = −0.040, P = 0.75) and ART (r = −0.071, P = 0.57).Conclusion: The RT is shorter in students with high academicperformance and longer in students with low academicperformance.
ABSTRACT
Primary testicular lymphomas (PTL) are rare entities representing 1-2% of Non-Hodgkin's Lymphoma (NHL) and 1-7% of malignant testicular tumours. They are most commonly seen in men older than 60 years. The most common type of primary testicular lymphoma (PTL) is diffuse large B-cell type which has the potential for aggressive clinical behaviour. We report the case of a 45 years old male with primary testicular lymphoma which was first diagnosed on Fine Needle Aspiration Cytology (FNAC) and subsequently confirmed histopathologically and immunophenotypically as Diffuse Large B-Cell Lymphoma (DLBCL) showing CD20 positivity. This case report confirms the literature data concerning the rarity of testicular Non Hodgkin's Lymphoma (TNHL) with DLBCL being the most common phenotype and the poor prognosis of the disease despite aggressive management.
