Development and Validation of a Bedside Dengue Severity Score for Predicting Severe Dengue in Children.

Objective: To develop and validate a bedside dengue severity score in children less than 12 years for predicting severe dengue disease.

Methods: We carried out an analysis of data on the clinical and laboratory parameters of patients with confirmed dengue, hospitalized in October, 2019 at our center. A comprehensive patient's score was developed.

Pediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2.

Objectives: To know the clinical presentation and outcome of children with pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV- 2 (PIMS-TS) at a pediatric tertiary care center in Chennai.

Methods: Clinical and biochemical parameters of 65 children with PIMS-TS treated between July and October 2020 were studied. All children had their COVID RT-PCR and IgG COVID antibodies tests done.

Neonatal diabetes caused by a homozygous KCNJ11 mutation demonstrates that tiny changes in ATP sensitivity markedly affect diabetes risk.

Aims/hypothesis: The pancreatic ATP-sensitive potassium (KATP) channel plays a pivotal role in linking beta cell metabolism to insulin secretion. Mutations in KATP channel genes can result in hypo- or hypersecretion of insulin, as in neonatal diabetes mellitus and congenital hyperinsulinism, respectively. To date, all patients affected by neonatal diabetes due to a mutation in the pore-forming subunit of the channel (Kir6.

Risk factors for mortality in children with diabetic keto acidosis from developing countries.

Diabetic keto acidosis (DKA) is the major cause for mortality in children with Diabetes mellitus (DM). With increasing incidence of type 1 DM worldwide, there is an absolute increase of DM among children between 0-14 year age group and overall incidence among less than 30 years remain the same. This shift towards younger age group is more of concern especially in developing countries where mortality in DKA is alarmingly high.

Novel ABCC8 (SUR1) gene mutations in Asian Indian children with congenital hyperinsulinemic hypoglycemia.

Congenital hyperinsulinemic hypoglycemia (HI) is a heterogeneous genetic disorder of insulin secretion characterized by persistent hypoglycemia, most commonly associated with inactivating mutations of the β-cell ATP-sensitive K(+) channel (K(ATP) channel) genes ABCC8 (encoding SUR1) and KCNJ11(encoding Kir6.2). This study aimed to screen the mutations in the genes associated with congenital HI in Asian Indian children.

EIF2AK3 mutations in South Indian children with permanent neonatal diabetes mellitus associated with Wolcott-Rallison syndrome.

Objective: This study describes the clinical and genetic evaluation of permanent neonatal diabetes due to Wolcott-Rallison syndrome (WRS) in south Indian consanguineous families. We aimed to evaluate the genetic basis of the disease in eight children with WRS from five South Indian families.

Patients And Methods: We studied eight children who presented with permanent neonatal diabetes from five South Indian families.

hypertensive intracranial bleed due to mid aortic syndrome.

The authors describe an 11-y-old child with intracranial bleed due to malignant hypertension. Child presented with hypertension, right hemiparesis, feeble femoral pulses and lower limb blood pressure less than the upper limb. CT angiogram revealed narrowing of the abdominal aorta with thinned out left renal artery and hypoplasia of the left kidney.

Clinical and molecular characterization of neonatal diabetes and monogenic syndromic diabetes in Asian Indian children.

Mutations in the pancreatic ATP sensitive K(+) channel proteins [sulfonyluea receptor 1 (SUR1) and inward rectifier K(+) channel Kir6.2 (Kir6.2), encoded by ATP-binding cassette transporter subfamily C member 8 (ABCC8) and potassium channel J11 (KCNJ11), respectively], are the most common cause of neonatal diabetes.

Clinical profile of scrub typhus in children.

Objective: To study the clinical profile and outcome of scrub typhus cases admitted in an urban referral centre.

Methods: This descriptive study describes the clinical profile of 67 children with scrub typhus, who were admitted in an urban referral centre(ICH & HC,Chennai) during the period between October 2010 and March 2011.The diagnosis was confirmed by IgM ELISA.

Pressurised air injury in a child.

We report the case of a 7 year old girl, who sustained accidental injury following injection of pressurized air from a bicycle tyre air nozzle. She presented with generalized subcutaneous emphysema along with pneumomediastinum, pneumothorax, pneumoperitoneum, pneumoretroperitoneum and pneumorra-chis. The child was recovered completely on conservative management.
