Intragenomic Decarboxylation associated with 5-Carboxy-2'-deoxycytidine.
The overall practical conclusion is that the placement and design of the air purifier and ventilation systems significantly affect the droplet dispersion and AVT. Thus, engineering designs of such systems must take into account the flow dynamics in the confined space the systems will be installed.The autoimmune rheumatic diseases (ARDs) are characterised by a pathological triad composed of autoimmunity/inflammation, microangiopathy and aberrant tissue remodelling. Disease terms such as idiopathic inflammatory myopathy (IIM), scleroderma/systemic sclerosis (SSc), and systemic lupus erythematosus (SLE) are helpful clinically but disguise the considerable overlap that exists within these 'distinct' disorders. This is perhaps best demonstrated by inflammatory myopathy, which can be present in SSc or SLE, but can itself be absent in clinically amyopathic IIM. Archetypal clinical manifestations of ARD (such as Raynaud's phenomenon) are frequently present, albeit with varying prominence, within each of these diseases. This is certainly the case for inflammatory myositis, which has long been recognised as an important clinical feature of both SSc and SLE. Progress in elucidating the clinicoserological spectrum of autoimmune rheumatic diseases has identified autoantibody specificities that are strongly associated with 'overlap' disease and the presence of inflammatory myositis in SSc and SLE. In this review, we shall describe the prevalence, burden, prognostic value and management considerations of IIM in the context of both SSc and SLE. A major emphasis on the value of autoantibodies shall highlight the value of these tools in predicting the future occurrence of inflammatory myositis in both SSc and SLE. Where applicable, unmet research needs shall be highlighted. The review emphasises the importance of myopathy as a common feature across all the ARDs, and highlights specific antibody specificities that are strongly associated with myopathy in the context of SLE and SSc.How to cite this article Mahajan C, Singh BP, Kapoor I, Prabhakar H.

Atypical presentation often misleads the diagnosis leading to a delay in early intervention, and a strong clinical suspicion is indeed required to diagnose the condition. Definitive treatment being surgical repair, endoscopic intervention can be attempted in nonseptic patients. How to cite this article Kaladhar S, Nikilesh Kumar G, Misra KC, Hemanth C, Appasani S.

The amount of fluid drained and the degree of pleural suction influence the development of RPE. We present a case of RPE in a critically ill patient of scrub typhus with rheumatic heart disease, after draining only 800 mL of pleural fluid, thereby proving that the complex cardiac and pulmonary interactions play an important role in the development of RPE.

A 66-year-old Caucasian male presented with worsening dyspnea and subsequently had a cardiac catheterization for an ST-elevation myocardial infarction, revealing no evidence of coronary artery disease but multiple coronary-cameral fistulas. Venoarterial (VA) extracorporeal membrane oxygenation was initiated for a severe cardiogenic shock. Workups including a transesophageal echocardiography and a right heart catheterization led to a diagnosis of metastatic melanoma involving both ventricles of his heart. Angiogenesis is well described in melanomas and our novel case reports the extremely rare association of coronary-cameral fistulas with a metastatic cardiac melanoma.

This is a case report of a young north Indian man who presented to the emergency room in a comatose state and distributive shock. He was initially managed with intravenous crystalloids but required inotropic therapy to maintain the desired mean arterial pressure and organ perfusion and also required mechanical ventilation. He improved during the hospital stay only after 4 days when cocktail treatment of atropine was started considering the possibility of organophosphorus toxin exposure and had tapered off the inotropes and mechanical ventilation. Dichlorvos ingestion was confirmed later on after recovery from the coma. At 4-week follow-up, he developed delayed neuropathy. This case is a torchlight toward organophosphorus poisoning presenting as a distributive shock. Atropine may be used as a cocktail treatment in distributive shock where the diagnosis is uncertain.

It has changed the infection control practices of most ICUs all over the world. Prevention is better than cure is definitely proven true as there is no definite cure for COVID-19 yet. Personal protective equipment and hand hygiene are a must while handling any suspected COVID-19 patient. Apart from that, there are several other things, which should be followed in ICU and specifically while caring for a patient on ventilator. There are a large number of interventions done while treating any critically ill patient in ICU, which can generate aerosols and exaggerate spread of COVID-19, which include high-flow nasal cannula, NIV, nebulization, suctioning, bag and mask ventilation, endotracheal intubation, and bronchoscopy. We will be reviewing those things beyond PPE and hand hygiene along with the rationale of each of them, which can help to minimize the risk of exposure to healthcare workers and other patients in the surrounding. It will help not only to prevent COVID-19 transmission but also to reduce overall nosocomial infection rate. As per our knowledge, this will be the first paper reviewing innovative ideas to minimize the risk of infection in a comprehensive manner.

This retrospective observational study was carried out over a period of 5 years from January 2015 to December 2019. Thirty-five cases of culture-confirmed melioidosis were identified with age range between 5 and 74 years. A large number of patients (n = 31) presented with uncontrolled diabetes mellitus. Six patients died of septic shock, and the outcome of eight patients was unknown as they were discharged against medical advice. There were no relapses observed. Melioidosis growing as a neglected tropical disease in India warrants awareness among all clinicians across the country. How to cite this article Ganesan V, Murugan M, Sundaramurthy R, Soundaram GVG.

Background RT-PCR test is a standard method for the diagnosis of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections. This test is based upon the amplification of the fluorescent signal. The number of cycles that the fluorescent signal undergoes to reach the threshold is called "cycle threshold." It is inversely related to the nucleic acid content of the sample. Patients and methods This is a single-centered, retrospective observational study. We have included a total of 192 patients. SARS-CoV-2 infection was confirmed by the RT-PCR test. Entire data have been collected from the electronic medical records. The primary outcome was 28-day mortality, whereas the secondary outcomes were intensive care unit (ICU) admission, invasive ventilation, acute kidney injury, renal replacement therapy (RRT), shock, and COVID-19 reporting and data system (CO-RADS) score on high-resolution computed tomography of the chest, total length of stay in the hospital, and the number of ICU days and ventilator days. Results We have calculated the mean CT value for all groups and calculated the p-value for statistical significance. For the total length of stay in the hospital and the number of ICU days and ventilator days, we applied the Pearson correlation coefficient. The p-value was statistically significant for mortality, ICU admission, and shock groups. The CT values and the length of ICU stay were inversely correlated with the statistically significant p-value. Conclusion Low CT value is associated with increased ICU admission, high mortality, shock, and increased length of ICU stay. How to cite this article Rajyalakshmi B, Samavedam S, Reddy PR, Aluru N.

Indian J Crit Care Med 2021;25(3)322-326.Background Coronavirus disease (COVID-19) is an infectious disease caused by SARS-CoV-2, clinically presenting with common symptoms of fever, dry cough, and breathlessness within 14 days of exposure. Its severity ranges from mild to severe, latter manifesting into severe acute respiratory syndrome. As a part of multidisciplinary team, physiotherapy along with medical management was administered to patients with COVID-19 in an acute care setup. This retrospective study aims to explore various patient characteristics and will aid in identifying the impairments associated with the disease, giving a direction to the physiotherapy community in planning future management strategy to improve quality of life. Patients and methods The present study is a unicentric study wherein prospective analysis of retrospective data of patients referred for physiotherapy from May 13 to July 31, 2020, was performed. (i) Characteristics of patients, (ii) associated comorbidities, (iii) hospital course since the time of admission to discharge, (iv) mode of oxygen delivery, (v) pre- and post-physiotherapy treatment values of oxygen saturation and heart rate, and (vi) physiotherapy treatment were recorded.
