Background: Corona virus disease 2019 (COVID 19) is caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection.This disease,which is quickly spreading worldwide,has high potential for infection and causes rapid progression of lung lesions,resulting in a high mortality rate.This study aimed to assess the severity and prognosis in COVID-19 patients based on lung involvement(CT-Chest). Methods: All lab confirmed cases of Covid 19 (RT-PCR positive) 369 patients admitted in Government Kilpauk medical college who were on follow up from october to november 2020, in Chennai were included. All patients underwent complete laboratory data including imaging studies-X-ray and CT- chest. Results:Among 369 of the admitted patients,67% were males,38% in 20-40 years 36% in 40-60 years of age.Among that 280 (75.9%) had non severe disease,89(24.12%) had severe disease.Regarding diseases outcome 38(10.3%) died and 331(89.7%) are alive.Compared to the patients with the stages of COVID-19: Asymptomatic (no lung involvement) - 28.4% Mild – Stage I (score I to II – 5 to 25% area involved) -36.3% Moderate – Stage II (score II to IV – 25 to 50% area involved) - 22.5% Severe – Stage III (score IV to V - more than 50% area involved} – 12.7% 12.7% of patients need ICU admission & mechanical ventilation and 10.3% of patients succumbed to death. Conclusion:From this study we have assessed the patient severity by using CT chest in covid 19 RT PCR positive patient. According to this study patient had more severe lung involvement needs mechanical ventilation and ICU admission

Primary Pulmonary Hypertension is a rare disease occurring in 1-2 per million population. It is 2-4 times more common in female. Idiopathic or primary pulmonary hypertension is defined as a disorder with no identifiable cause in which resting mean pulmonary artery pressure in adults is above 25 mmHg and 30 mmHg with exercise. Idiopathic or primary pulmonary hypertension is diagnosed after ruling out all the possible secondary causes of pulmonary hypertension. We are presenting a case of middle-aged male who presented with dyspnoea and on further evaluation found to have primary pulmonary hypertension, which is uncommon in male. KEYWORDSPrimary Pulmonary Hypertension, Dyspnoea. On examination, patient was dyspnoeic and tachypnoeic. He was not pale, not icteric; no cyanosis, no clubbing and no bilateral pitting pedal oedema. JVP was elevated and pressure was 12 cm of blood. Pulse 86/min, normal volume, regular rhythm and BP -100/70 mmHg. On examination of cardiovascular system, P2 was palpable, parasternal heave of grade 2 was present, epigastric pulsations were noted. On auscultation second heart sound was loud in pulmonary area with narrow split, ejection systolic murmur heard in the pulmonary area. Mitral, tricuspid and aortic areas S1, S2 heard normally. No other murmur heard. Respiratory system, Gastrointestinal system and Central Nervous System was clinically normal. Clinical features suggested pulmonary hypertension, but the aetiology could not be determined clinically. Patient was further investigated. HOW TO CITE THIS ARTICLE:Complete blood count was normal, urea 36 mg, creatinine 0.9 mg, serum electrolytes were within normal limits.Chest X-ray PA view showed dilated main pulmonary artery with cardiomegaly.
