Multisystem Inflammatory Syndrome in Children: Follow-Up of a Cohort from North India.

Multisystem inflammatory syndrome in children (MIC-S) is a hyperinflammatory manifestation of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Information on the long-term outcome of MIS-C is limited. This study was conducted to describe the long-term outcome of MIS-C from a tertiary care center in North India. Children admitted with MIS-C from September 2020 to January 2021 were followed up after discharge until June 2021. The details during the acute phase (clinical features, investigations, treatment, and outcome) and follow-up (symptoms, echocardiographic findings, ongoing treatment, and outcome) were collected retrospectively. During the acute phase, 40 children presented at median (interquartile range [IQR]) age of 7 (5-10) years with fever, mucocutaneous, gastrointestinal, and respiratory symptoms. The majority (66.7%) of the children had positive SARS-CoV-2 serology and elevated inflammatory markers (C-reactive protein, procalcitonin, ferritin, D-dimer, and fibrinogen), lymphopenia, and thrombocytopenia. Eighty percent had shock, 72.5% had myocardial dysfunction (left ventricular ejection fraction <55%), and 22.5% had coronary artery dilatation or aneurysm. Treatment included pediatric intensive care unit admission (85%), intravenous immunoglobulin (100%), steroids (85%), aspirin (80%), vasoactive drugs (72.5%), and invasive mechanical ventilation (22.5%). Two (5%) children died because of refractory shock. Thirty-four children were followed up with until a median (IQR) of 5 (3-6) months. During the follow-up, a majority were asymptomatic, myocardial function returned to normal in all, and only one had coronary artery aneurysm. Prednisolone and aspirin were given for a median (IQR) of 3 (2-4) weeks and 4 (4-6) weeks after discharge, respectively. There was one readmission and no death during the follow-up. To conclude, the long-term outcome of MIS-C is generally favorable with resolution of cardiovascular manifestations (myocardial dysfunction and coronary artery changes) in the majority of children during follow-up.

Fetal cardiac intervention and fetal cardiac surgery: where are we in 21st century?

Fetal cardiac intervention is an in-utero cardiac procedure done in fetuses with heart diseases like severe aortic stenosis with evolving hypoplastic left heart syndrome, hypoplastic left heart syndrome with an intact or restricted atrial septum, pulmonary atresia with an intact ventricular septum, fetal heart block obstructed total anomalous pulmonary venous return, pericardial collection. The successful biventricular repair can be done in postnatal life after aortic or pulmonary valvuloplasty. Fetal bypass is very challenging because of different physiology. Low prime volume with the high flow can be used to prevent an inflammatory response.

Infective endocarditis caused by Abiotrophia defectiva presenting as anterior mitral leaflet perforation mimicking cleft anterior mitral leaflet.

Infective endocarditis (IE) is primarily a bacterial infection of the heart valves. The most common organisms implicated include Staphylococcus and Streptococcus species. However, with the advent of MALDI-TOF and molecular techniques, the reports of IE being caused by rare organisms are on a rise. Here we describe a case of IE due to Abiotrophia defectiva. This is the first report of simultaneous infection of both mitral and aortic valves by Abiotrophia defectiva from India. IE caused by Abiotrophia defectiva has been seen to be more severe, associated with higher failure rates and relapse. This emphasizes the accurate identification of nutritionally variant Streptococcus (NVS) species as the management of choice varies between Abiotrophia and Granulicatella.

Fusobacterial brain abscess caused by paradoxical embolization associated with Ebstein's anomaly in an adult patient: A case report.

Brain abscess remains a life-threatening condition. Here, we are reporting a case of brain abscess due to Fusobacterium nucleatum in a previously known case of Ebstein anomaly. A 44-year-old male presented with the complaints of headache, and fever. Cerebral imaging revealed parieto-occipital (PO) abscess. The abscess was drained and culture showed growth of Fusobacterium nucleatum. This report illustrates the importance of considering anaerobes as the cause of brain abscess, underscores the usefulness of MALDI, which facilitated the selection of appropriate and prompt adjuvant antibiotic therapy and a favourable outcome.

Type II aortopulmonary window with tetralogy of Fallot: successful repair.

Aortopulmonary window associated with tetralogy of Fallot is a rare cardiac anomaly. An 8-month-old boy presented with failure to thrive and recurrent chest infections. Echocardiography and imaging studies revealed a type II aortopulmonary window with tetralogy of Fallot. Corrective surgery in the form of patch closure of the aortopulmonary window and intracardiac repair of tetralogy of Fallot was carried out successfully.
