Severity and Cardiac Involvement in Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory syndrome in children (MIS-C) occurs secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A retrospective study, involving 6 tertiary-care centers in Haryana, was conducted to evaluate the clinical features, severity, laboratory findings, and outcomes of patients with MIS-C. Disease severity was graded (mild/moderate/severe) and presence of cardiac abnormalities noted. Patients with and without cardiac abnormalities and with and without severe disease were compared. Forty-eight children with MIS-C were included (median age - 9.5 y). Fever (100%), gastrointestinal (83.3%) and mucocutaneous (50%) symptoms were common. Only 16.7% patients had previous history of documented SARS-CoV-2 infection/contact. Severe disease and cardiac abnormalities were seen in 47.9% and 54.2% patients, respectively. NT-proBNP > 1286.5 pg/mL and thrombocytopenia (≤ 119500/µL) were significant risk factors for severe MIS-C. Forty-five patients (93.8%) recovered and 3 died. Median hospitalization duration was 7 d (5-9.5). MIS-C must be considered as a possibility in any febrile child, even if a positive epidemiological history is absent. High NT-proBNP and thrombocytopenia are significant risk factors for severe MIS-C. (Trial Registration: The study was registered with the Clinical Trials Registry, India (CTRI/2021/09/036491)).

An international assessment of a web-based diagnostic tool in critically ill children.

Improving diagnostic accuracy is essential. The extent of diagnostic uncertainty at patient admission is not well described in critically ill children. Therefore, we studied the extent that pediatric trainee diagnostic performance could be improved with the aid of a computerized diagnostic tool. Data regarding patient admissions to five Pediatric Intensive Care Units were collected. Information included patients' clinical details, admitting team's diagnostic workup and discharge diagnosis. An attending physician assessed each case independently and suggested additional diagnostic possibilities. Diagnostic accuracy was calculated using the discharge diagnosis as the gold standard. 206 out of 927 patients (22.2%) admitted to the PICUs did not have an established diagnosis at admission. The trainee teams considered a median of three diagnoses in their workup (IQR 3-5) and made an accurate diagnosis in 89.4% cases (95% CI 84.6%-94.2%). Diagnostic accuracy improved to 92.5% with use of the diagnostic tool alone, and to 95% with the addition of attending physicians' diagnostic suggestions. We conclude that a modest proportion of admissions to these PICUs were characterized by diagnostic uncertainty during initial assessment. Although there was a relatively high accuracy rate of initial assessment in our clinical setting, it was further improved by both the diagnostic tool and the physicians' diagnostic suggestions. It is plausible that the tool's utility would be even greater in clinical settings with less expertise in critical illness assessment, such as community hospitals, or emergency departments of non-training institutions. The role of diagnostic aids in the care of critically ill children merits further study.further study.

Comparison of cord blood vitamin D levels in newborns of vitamin D supplemented and unsupplemented pregnant women: a prospective, comparative study.

OBJECTIVE: To screen pregnant women for deficiency of 25-hydroxyvitamin D (25(OH)D) and supplement selected vitamin D deficient pregnant women with vitamin D and to compare 25(OH)D levels in cord blood between them. METHOD: Sixty pregnant women were selected as cases (vitamin D levels <30 ng/ml) and 60 unscreened pregnant women were taken as controls. Cases were supplemented with available 60,000 IU vitamin D every two weeks for eight doses or till delivery, whichever was earlier. In both the cases and controls, cord blood was collected at the time of delivery and tested for 25(OH)D levels using Biomerieux miniVIDAS. RESULT: Maximum (66.7%) pregnant women who received vitamin D supplementation had cord blood vitamin D level >30 ng/ml, while only 3.3% unsupplemented pregnant women had cord blood vitamin D level >30 ng/ml. The median cord blood vitamin D level was 36.5 ng/ml in vitamin D supplemented and 11.35 ng/ml in unsupplemented women. The mean birth weight and mean crown heel length were 3.1 ± 0.485 kg versus 2.8 ± 0.705 kg and 49.35 ± 1.36 cm versus 48.67 ± 2.12 cm, respectively. CONCLUSION: Vitamin D supplemented women had sufficient levels of 25(OH)D in cord blood at birth in maximum cases and neonates had higher birth weights and increased crown heel length.

Perinatal tuberculosis associated hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis [HLH] is a reactive disorder characterized by generalised non-malignant histiocytic proliferation with prominent hemophagocytosis. It may be either primary [familial (FLH)] or secondary [infection or malignancy associated]. Organisms incriminated for infection associated hemophagocytic syndrome (IAHS) include viruses, bacteria, spirochetes, fungi and parasites. Reports of IAHS associated with tuberculosis in neonates are rare. The authors report a case of perinatal tuberculosis presenting as hemophagocytic lymphohistiocytosis.
