Indian J Pediatr 2021 Mar 8;88(Suppl 1):97-104. Epub 2021 Feb 8.

The Wellcome Trust Research Laboratory, Christian Medical College, Vellore, Tamil Nadu, India.

Objective: To determine the clinical and epidemiological profile and circulating strains of rotavirus among children less than 5 y of age hospitalized for diarrhea in a tertiary care center of western Rajasthan.

Method: Children < 5 y of age admitted for acute gastroenteritis were recruited in this hospital-based surveillance study. Detailed clinical history and sociodemographic information was collected for all enrolled children. Severity of the gastroenteritis was assessed using the 20-point Vesikari Clinical Severity Scoring System. Rotavirus positivity was tested in the stool samples collected from children by commercially available techniques and further molecular characterization done as per defined protocol.

Results: Out of 1055 enrolled children, overall positivity rate of typable rotavirus was 18.95% (169/892). Among children who were less than 24 mo of age, positivity due to rotavirus diarrhea was maximum (24.4%). Distinct seasonality was observed as maximum cases of rotavirus diarrhea were detected in the months of December to February. Commonest G type was G3 (54%) followed by G1 (19%) while predominant P type was P[8] (77%) followed by P[4] (11%). G3P[8] (51.83%) was the commonest genotype observed in the study region.

Conclusion: The current study found positivity of rotavirus to be 18.95% among children aged 0-59 mo admitted due to acute gastroenteritis is a tertiary care setting in northern part of India. Emergence of newer predominant strains emphasizes the need of continued surveillance to determine the changing trends.

A Hospital-Based Multi-Centric Study to Determine the Clinico-Epidemiological Profile of Intussusception in Children < 2 Years in Rajasthan, India.

Indian J Pediatr 2021 Mar 6;88(Suppl 1):131-137. Epub 2021 Jan 6.

Christian Medical College, Vellore, Tamil Nadu, India.

Objective: To determine the clinical and epidemiological profile of Intussusception in children aged <2 y after introduction of rotavirus vaccine in Universal Immunization Programme of Rajasthan.

Method: This was a hospital-based multi-centric surveillance study conducted at three tertiary care sentinel sites in Rajasthan over a period of 2 y. Children <2 y of age admitted with intussusception as per Brighton's criteria 1 were enrolled. Demographic details including age, sex, clinical presentation, diagnostic methods, duration of symptoms, mode of treatment, and complications were recorded and analyzed.

Results: During the study period of 2 y, the authors identified 164 cases of intussusception based on level-1 Brighton's criteria. Median age at presentation was 7 mo [Interquartile range (IQR) 5-10 mo] with a male to female ratio of 2:1. Pain abdomen and blood stained stool were the commonest presenting complaints (88.4% and 81.7%, respectively). Commonest site of intussusception was Ileocolic (82.32%). Pathological lead point was identified in 18.9% cases. Distinct seasonality was observed as maximum cases of intussusception were detected in the months of Jan-March (34.1%). Surgical intervention was required in the 89.63% cases. The median time duration between onset of symptoms and admission at sentinel site was 2 d (IQR 1-3 d). Proportion of cases that required surgery increased as the time interval between onset of symptoms and admission increases.

Conclusion: Intussusception is a common surgical condition among children under-two years of age with majority of cases occurring during infancy. Case management is dependent primarily on time duration elapsed between symptoms onset and admission to tertiary care centre. Early case detection and timely referral may provide an opportunity to avoid surgical interventions.

The Burden of Rotavirus Gastroenteritis in Children: A Hospital-Based Prospective Study in Western Rajasthan.

Cureus 2020 Oct 18;12(10):e11020. Epub 2020 Oct 18.

Psychiatry, Griffin Memorial Hospital, Norman, USA.

Objective  Rotaviruses are the prime cause of gastroenteritis amongst infants and young children worldwide. In India, the mortality and economic impact caused by rotavirus are high. The objective of this is to understand the burden of rotavirus in acute watery diarrhea and its circulating genotypes in hospitalized children less than five years of age for acute gastroenteritis in western Rajasthan. Methodology This is a hospital-based prospective study conducted in the pediatrics department of Dr. Sampurnanand (S.N.) Medical College of Jodhpur in India for one year during 2018. The study included 399 children less than five years old, presenting with acute gastroenteritis who needed to be admitted for at least six hours. We enrolled subjects after obtaining informed consent from the guardian. Stool samples of 5 gm or ml were collected in a sterile container and stored at minus 20 degrees centigrade while transporting to Christian Medical College (CMC) virology lab in Vellore, India. The stool samples were subjected to Enzyme-Linked Immunosorbent Assay (ELISA) testing, followed by genotype determination. We investigated data through statistical analysis from all collected data. Results A total of 399 patients fulfilled the enrollment criteria; out of them, 92 (23.05%) were positive for rotavirus, and maximum cases were seen in the age group of six months to two years (78.26%). Rotavirus positivity was more in males (64.13%) than females (35.86%). The rotavirus infection was seen throughout the year, with a peak in cases from November to February (73.91%). G3P8 (55.43%) was the most common strain causing rotavirus diarrhea, followed by G1P8 (9.72%) and G3+G12P8 (8.69%). Based on the Vesikari clinical severity score, 70.65% of patients had severe diarrhea. Conclusion This prospective study highlights the healthcare and economic burden of rotavirus, especially in children of less than five years. The incidence of rotavirus is observed in winter months, and its prevalence in all cases of acute diarrhea in our study is 23.05%. G3P8 was the most common genotype causing rotavirus diarrhea in our region in both non-vaccinated and vaccinated children, followed by G1P8 and G3+G12P8, respectively.

Indian J Pediatr 2018 Nov 12;85(11):978-983. Epub 2018 May 12.

Department of Obstetrics & Gynaecology, Dr. S. N. Medical College, Jodhpur, Rajasthan, India.

Objectives: To evaluate the Quality of life (QoL) and the factors affecting it in transfusion-dependent thalassemic children.

Methods: Current study was conducted at Department of Pediatrics, Dr. SNMC, Jodhpur. Ninety-three transfusion-dependent thalassemic children aged between 8 and 18 y were enrolled. Quality of life was assessed using Pediatric Quality of Life (PedsQL) measurement model in thalassemic children.

Results: Mean age of children was 11.8 ± 3.2 y. Lowest mean score was observed in School functioning (57.4) while in Physical functioning, Emotional functioning and Social functioning it was 73.9, 82.2 and 83.49 respectively. Mean PedsQL score was higher in 8-12 y age group as compared to 13-18 y (p = 0.024). PedsQL score was higher in children who required transfusion once in a month (p = 0.028) and children on combined chelation therapy as compared to children who were on injectable chelator (p = 0.039). Health Related QoL was not affected with gender, education status, family history of thalassemia, ferritin level, splenectomy or consanguinity.

Conclusions: Factors related with low QoL in current study were higher age, increased transfusion frequency and injectable mode of chelation. In order to improve the QoL in thalassemic children appropriate programmes and interventions should be started targeting above domains.

Non-pharmacologic management of epilepsy.

Indian J Pediatr 2014 Oct 5;81(10):1073-80. Epub 2014 Jul 5.

Department of Pediatric Medicine, Dr S N Medical College, Jodhpur, Rajasthan, India,

Non pharmacological treatment, in addition to pharmacological treatment is indicated in patients with refractory/pharmacoresistant epilepsy and includes ketogenic diet, deep brain stimulator, vagal nerve stimulator, transcranial magnetic stimulation and epilepsy surgery. Ketogenic diet has been recommended since 1921 and has been proved to be a safe and effective treatment for intractable epilepsy. Deep brain stimulator, has been used in the treatment of movement disorders for many years and recently been tried in the treatment of pharmacoresistant epilepsy. Vagus nerve stimulator is increasingly being used as an effective seizure aborting technique in patients not responding to anticonvulsants. Transcranial magnetic stimulation is a noninvasive brain stimulation technique which is being increasingly researched for use in patients with medication-refractory seizures who are not suitable candidates for surgery. Evolution of epilepsy surgery including Vagal nerve stimulator and Deep brain stimulator, as a successful treatment modality for intractable epilepsy has been influenced over the last decade by substantial advancement in imaging and operative/device related technology. The current article reviews the indications, mechanism of action, technological aspects and efficacy of the aforementioned modalities in the treatment of intractable/pharmacoresistant epilepsy in pediatric age group.
