The profile of epilepsy and its characteristics in children with neurocutaneous syndromes.

Objectives: The profile of seizures in neurocutaneous syndromes is variable. We aimed to define the characteristics of epilepsy in children with neurocutaneous syndromes. Materials and Methods: Cross-sectional study over 18 months at a tertiary care pediatric hospital, including children with neurocutaneous syndromes aged between 1 and 15 years, using the 2017-International League Against Epilepsy classification. Results: In 119 children with neurocutaneous syndromes, 94 (79%) had epilepsy. In eight children with neurofibromatosis one with epilepsy, 5 (62.5%) had generalized motor tonic-clonic seizures, 1 (12.5%) had generalized motor epileptic spasms, 1 (12.5%) had generalized motor automatism, and 1 (12.5%) had a focal seizure. In 69 children with tuberous sclerosis complex with epilepsy, 30 (43.5%) had generalized motor epileptic spasms, 23 (33.3%) had focal seizures, and nine (13.0%) had generalized motor tonic-clonic seizures. In 14 children with Sturge-Weber syndrome with epilepsy, 13 (92.8%) had focal seizures, and 1 (7.2%) had generalized motor tonic seizures. Statistically significant associations were found between epilepsy and intellectual disability (P = 0.02) and behavioral problems (P = 0.00). Conclusion: Profiling seizures in children with neurocutaneous syndromes are paramount in devising target-specific treatments as the epileptogenesis in each syndrome differs in the molecular pathways leading to the hyperexcitability state. Further multicentric studies are required to unravel better insights into the epilepsy profile of neurocutaneous syndromes.

In-vitro antioxidant and anti-inflammatory potential along with p.o. pharmacokinetic profile of key bioactive phytocompounds of Snow Mountain Garlic: a comparative analysis vis-à-vis normal garlic.

Snow mountain garlic (SMG) is a trans-Himalayan medicinal plant used in the traditional medicine system for several ailments, including inflammatory arthritis. Research studies are insufficient to validate its folk medicinal applications. In the present study, the comparative abundance of its key bioactive phytocompounds, viz., S-allyl-L-cysteine (SAC), alliin, and S-methyl-L-cysteine (SMC) against normal garlic were assessed using the LC-MS/MS-MRM method. In addition, the study also explored the antioxidant and anti-inflammatory potency of crude extract of SMG and purified signature phytocompounds (i.e., SMC, SAC, and alliin) in comparison with normal garlic and dexamethasone in LPS-stimulated RAW264.7 macrophage cells. The LC-MS/MS-MRM study revealed significant differences among SMG and normal garlic, viz., alliin 22.8-fold higher in SMG, and SMC could be detected only in SMG. In the bioassays, SMG extract and purified signature phytocompounds significantly downregulated oxidative damage in activated macrophages, boosting endogenous antioxidants' activity. SMG extract-treated macrophages significantly suppressed NF-κB expression and related inflammatory indicators such as cytokines, COX-2, iNOS, and NO. Notably, the observed anti-inflammatory and antioxidant bioactivities of SMG extract were comparable to signature phytocompounds and dexamethasone. In addition, SAC being uniformly found in SMG and normal garlic, its comparative pharmacokinetics was studied to validate the pharmacodynamic superiority of SMG over normal garlic. Significantly higher plasma concentrations (Cmax), half-life (t1/2), and area under curve (AUC) of SAC following SMG extract administration than normal garlic validated the proposed hypothesis. Thus, the abundance of bioactive phytocompounds and their better pharmacokinetics in SMG extract might be underlying its medicinal merits over normal garlic.

Exploring the combined effect of heavy metals on accumulation efficiency of Salix alba raised on lead and cadmium contaminated soils.

The present study illustrated that Salix alba can accumulate high level of Pb and Cd in different plant parts, with maximum accumulation in roots followed by stem and leaves in the order Cd > Pb > Cd + Pb. The phytoremediation evaluation factors such as bioconcentration factor (BCF) and translocation factor (TF) was higher for Cd over Pb in all plant parts, further the BCF for both Pb and Cd was maximum in root (BCF > 1) followed by stem and leaves. Higher accumulation of Cd over the Pb was observed inside the plant tissues due to Cd mimics with other elements and gets transported through respective transporters. The combined treatment of Pb and Cd affected the bioaccumulation at every treatment level suggesting the negative effect among both elements. Higher survival rate (>85%) was recorded up to 200mgPb/kg and 15mgCd/kg, while further increase in metal concentration reduced the plant efficiency to remediate contaminated soils, hence results in declined survival rate. The FTIR analysis revealed that Pb and Cd accumulation in plants induced changes in carboxy, amino, hydroxyl and phosphate groups that ultimately caused alteration in physiological and biochemical processes of plant and thus provided an insight to the interaction, binding and accumulation of heavy metals.

The present study conferred that Salix alba is a heavy metal (Pb and Cd) excluder plant on the basis of phytoremediation efficiency evaluation factors such BCF >1 (root) and TF <1. The correlation studies suggested the negative correlation among Pb and Cd accumulation and morphological traits. Physiological studies indicated that Pb and Cd accumulation negatively affect chlorophyll concentration and the antioxidant mechanism of plants gets activated, further these results are confirmed with FTIR studies, which reported the alteration in functional groups and associated compounds in plant tissues under Pb and Cd stress.

X-Linked Lymphoproliferative Syndrome: A Spectrum of Clinical and Immunological Profile and Novel Pathogenic Variants from Chandigarh, India.

INTRODUCTION: X-linked lymphoproliferative syndrome (XLP) is a rare primary immune deficiency. Two types of XLP have been described: XLP-1 and XLP-2. METHODS: We found 7 patients with XLP (3 had XLP-1 and 4 had XLP-2) after reviewing the data from Pediatric Immunodeficiency Clinic from 1997 to 2021. RESULTS: Mean age at diagnosis was 3.8 years, and mean delay in diagnosis was 2.6 years. Five patients had recurrent episodes of infections. Four patients developed at least one episode of hemophagocytic lymphohistiocytosis (HLH) (2 with XLP-1 and 2 with XLP-2). Of these, 2 had recurrent HLH (both with XLP-2). Epstein-Barr virus (EBV) infection was detected in 2 (1 with XLP-1 and 1 with XLP-2). Both these patients had HLH. One child with XLP-2 had inflammatory bowel disease. Hypogammaglobulinemia was seen in 3 (2 with XLP-1 and 1 with XLP-2). Genetic analysis showed previously reported variants in 5, while 2 had novel variants (one in exon 7 of XIAP gene [c.1370dup p.Asn457Lysfs Ter16] and other had splice site variant in intron 1 of SH2D1A gene [c.138-2_138-1insG]). Episodes of HLH were managed with intravenous immunoglobulin (IVIg), methylprednisolone, oral prednisolone, cyclosporine, and rituximab. Inflammatory bowel disease was managed using oral prednisolone and azathioprine. One patient underwent haploidentical hematopoietic stem cell transplantation. One child with XLP-2 and WAS died because of fulminant pneumonia. DISCUSSION/CONCLUSIONS: XLP should be considered as a strong possibility in any patient with features of HLH, repeated infections with hypogammaglobulinemia, persistent EBV infection, and early-onset IBD.

Tolvaptan for Treatment of Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) in a Child with Corpus Callosum Agenesis.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is one of the common causes of euvolemic hyponatremia (serum Na+ < 135 mEq/L) in hospitalized children. It is characterized by increased serum ADH, leading to water retention via its action on V2 receptors in the distal renal tubules. Various conditions such as pain, the postoperative state, drugs, central nervous system infections, tumors, malformations, and pneumonia can predispose a person to SIADH. The conventional treatment of SIADH includes fluid restriction and salt supplementation. Occasionally, this may fail to control hyponatremia, mandating pharmacological therapy. V2-receptor antagonists are an FDA-approved therapy for adults with euvolemic and hypervolemic hyponatremia. However, there is limited experience with their use in the pediatric population. Here, the authors present a girl with corpus callosum agenesis with severe symptomatic hyponatremia due to SIADH who was successfully managed with the V2-receptor antagonist tolvaptan.

Clinical, immunological and molecular profiles of DOCK8 deficiency in six patients from a tertiary care centre in North India.

BACKGROUND: Dedicator of cytokinesis protein 8 (DOCK8) deficiency is an autosomal recessive form of combined immunodeficiency. This rare disorder is characterized by an increased predisposition to allergy, autoimmunity and malignancies. OBJECTIVES: To analyse clinical, immunological and molecular profiles of patients with DOCK8 deficiency. METHODS: Clinic records of all patients attending the primary immunodeficiency clinic from 2018 to 2021 were reviewed. Six patients from five families were found to have DOCK8 deficiency. RESULTS: Median age at diagnosis was 7.5 years (range 2-13), with a male/female ratio of 5 : 1. Among the six patients, recurrent eczematous skin lesions were the predominant cutaneous manifestation, present in five patients (83%). Warts and molluscum contagiosum were evident in two patients (33%) and one patient (16%), respectively. Two patients had recalcitrant prurigo nodularis lesions and two had epidermodysplasia verruciformis-like lesions. Food allergies and asthma were reported by one patient each. Of the six patients, recurrent sinopulmonary infections were detected in five (83%). Epstein-Barr virus-driven non-Hodgkin lymphoma with liver metastases was the only case of malignancy, in a 4-year-old boy. IgE was elevated in all patients. Lymphopenia and eosinophilia were observed in three patients (50%) and five patients (83.3%), respectively. Genetic analysis showed DOCK8 pathogenic variants in all patients: homozygous deletion mutations in two patients, compound heterozygous deletion mutations in one, and homozygous nonsense mutations in two. A novel pathogenic homozygous missense variant in the DOCK8 gene was identified in one patient. CONCLUSIONS: DOCK8 deficiency should be considered as a possibility in any patient with early onset eczema, cutaneous viral infections and increased predisposition to allergy, autoimmunity and malignancy.

Serological response and breakthrough infection after COVID-19 vaccination in patients with cirrhosis and post-liver transplant.

BACKGROUND: Vaccine hesitancy and lack of access remain major issues in disseminating COVID-19 vaccination to liver patients globally. Factors predicting poor response to vaccination and risk of breakthrough infection are important data to target booster vaccine programs. The primary aim of the current study was to measure humoral responses to 2 doses of COVID-19 vaccine. Secondary aims included the determination of factors predicting breakthrough infection. METHODS: COVID-19 vaccination and Biomarkers in cirrhosis And post-Liver Transplantation is a prospective, multicenter, observational case-control study. Participants were recruited at 4-10 weeks following first and second vaccine doses in cirrhosis [n = 325; 94% messenger RNA (mRNA) and 6% viral vaccine], autoimmune liver disease (AILD) (n = 120; 77% mRNA and 23% viral vaccine), post-liver transplant (LT) (n = 146; 96% mRNA and 3% viral vaccine), and healthy controls (n = 51; 72% mRNA, 24% viral and 4% heterologous combination). Serological end points were measured, and data regarding breakthrough SARS-CoV-2 infection were collected. RESULTS: After adjusting by age, sex, and time of sample collection, anti-Spike IgG levels were the lowest in post-LT patients compared to cirrhosis (p < 0.0001), AILD (p < 0.0001), and control (p = 0.002). Factors predicting reduced responses included older age, Child-Turcotte-Pugh B/C, and elevated IL-6 in cirrhosis; non-mRNA vaccine in AILD; and coronary artery disease, use of mycophenolate and dysregulated B-call activating factor, and lymphotoxin-α levels in LT. Incident infection occurred in 6.6%, 10.6%, 7.4%, and 15.6% of cirrhosis, AILD, post-LT, and control, respectively. The only independent factor predicting infection in cirrhosis was low albumin level. CONCLUSIONS: LT patients present the lowest response to the SARS-CoV-2 vaccine. In cirrhosis, the reduced response is associated with older age, stage of liver disease and systemic inflammation, and breakthrough infection with low albumin level.

Association of Wilms tumor-1 protein in urinary exosomes with kidney injury: a population-based cross-sectional study.

Objective: Loss of Wilms tumor-1 (WT1) protein, a podocytopathy marker, through urine exosome (uE), could be an early indication of kidney injury. We examined WT1 in uE (uE-WT1), along with other urine markers of glomerular and kidney tubule injury, in individuals without chronic kidney disease (CKD). Methodology: The cross-sectional study included individuals who reported having no evidence of chronic kidney disease (CKD). Albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) were used to assess kidney function. eGFR was calculated using the 2009 CKD-EPI (CKD-Epidemiological) equation. WT1 was analyzed in uE from humans and Wistar rats (before and after the 9th week of diabetes, n = 20). uE-WT1, urinary neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) were estimated using ELISA. The Kruskal-Wallis H test, Mann-Whitney U test, and stepwise multivariable linear regression were performed. Results: Urine NGAL and ACR increase with uE-WT1 quartiles (n = 146/quarter). Similarly, uE-WT1, KIM-1, and NGAL were positively associated with ACR. Furthermore, KIM-1, NGAL, and uE-WT1 correlated with ACR. uE-WT1 outperformed KMI-1 and NGAL to explain ACR variability (25% vs. 6% or 9%, respectively). Kidney injury in streptozotocin-induced diabetic rats was associated with a significant rise in uE-WT1. Moreover, the findings were confirmed by the histopathology of kidney tissues from rats. Conclusion: uE-WT1 was strongly associated with kidney function in rats. In individuals without CKD, uE-WT1 outperformed NGAL as a determinant of differences in ACR.

Management protocol and surgical techniques for MRI-Negative Cushing's disease: a series of 6 cases.

Up to 40% of Cushing's disease (CD) patients show no evidence of an adenoma on dynamic contrast-enhanced MRI. Inferior petrosal sinus sampling (IPSS) remains the gold standard for diagnosis in these patients. Remission rates in MRI-Negative CD are far less at 50%-71%, compared with patients in whom an adenoma is identified on MRI. Endoscopic endonasal transsphenoidal surgery is the surgical approach of choice in these cases. Various adjuncts can be used to localize an adenoma. In this video, the authors highlight their additional usage of pituitary perfusion MRI for identification of the adenoma. They present their stepwise management algorithm and surgical techniques for sellar and suprasellar exploration in 6 cases of MRI-Negative CD operated on by the senior author (A.S.).

Impact of COVID-19 Pandemic on Clinical Care of Patients and Psychosocial Health of Affected Families with Chronic Granulomatous Disease: an Observational Study from North India.

Day-to-day clinical management of patients with inborn errors of immunity, including chronic granulomatous disease (CGD), has been affected by the coronavirus disease-2019 (COVID-19) pandemic. There is a dearth of information on impact of this pandemic on clinical care of children with CGD and psychological profile of the caretakers. Among the 101 patients with CGD followed up in our center, 5 children developed infection/complications associated with COVID-19. Four of these children had a mild clinical course, while 1 child developed features of multisystem inflammatory syndrome in children (MISC) requiring intravenous glucocorticoids. Parents and caretakers of CGD patients (n = 21) and 21 healthy adults with similar ages and genders were also evaluated on the following scales and questionnaires: COVID-19 Fear Scale (FCV 19S), Impact of Event Scale (IES-R), Depression, Anxiety, and Stress Scale (DASS 21), Preventive COVID-19 Behavior Scale (PCV 19BS), and a "COVID-19 Psychological wellbeing questionnaire." Median age of the parents/caregivers was 41.76 years (range: 28-60 years). Male:female ratio was 2:1. In the study group, 71.4% had higher IES scores compared to 14.3% in controls. The caregivers had a high prevalence of stress, anxiety, avoidance behavior, and depression compared to controls (p < 0.001). Children with CGD have had predominantly mild infection with COVID-19; however, caregivers/parents of these children were at risk of developing psychological distress. The COVID-19 pandemic has brought to light the importance of patients' and caretakers' mental health which needs periodic assessment and appropriate interventions.

Neurodevelopmental Outcomes of a Cohort of Children with Tuberous Sclerosis Complex with Epileptic Spasms.

The neurodevelopmental outcomes in children with tuberous sclerosis complex (TSC) with epileptic spasms remain underdiagnosed and might be responsible for significant morbidity and mortality burdens, even after spasms abate. The study was a cross-sectional study over 18 months at a tertiary care pediatric hospital, involving 30 children with TSC who had epileptic spasms. They were assessed with Diagnostic and Statistical Manual of Mental Disorders-5 criteria for autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and intellectual disability (ID), and childhood psychopathology measurement schedule (CPMS) for behavioral disorders. The median age at onset of epileptic spasms was 6.5 (1-12) months, and the age at enrolment was 5 (1-15) years. Of 30 children, 2 (6.7%) had only ADHD, 15 (50%) had only ID/GDD (global developmental delay), 4 (13.3%) had ASD and ID/GDD, 3 (10%) had ADHD and ID/GDD, and 6 (20%) had none. The median intelligence quotient/development quotient (IQ/DQ) score was 60.5 (20-105). CPMS assessment revealed significant behavioral abnormalities in almost half the children. Eight (26.7%) patients were completely seizure-free for at least 2 years, 8 (26.7%) had generalized tonic-clonic seizures, 11 (36.6%) had focal epilepsy, and 3 (10%) had evolved into Lennox-Gastaut syndrome. A high proportion of neurodevelopment disorders, including ASD, ADHD, ID/GDD, and behavioral disorders were seen in this pilot study with a small cohort of children with TSC with epileptic spasms.

Pediatric Adrenocortical Neoplasms: A Study Comparing Three Histopathological Scoring Systems.

Adrenocortical neoplasms are rare in childhood. Their histopathological categorization into benign and malignant is often challenging, impacting further management. While the AFIP/Wieneke scoring system is widely used for the prognostic classification of these tumors, it has limitations. Few other tumor scoring systems have evolved over the past few years. These have been validated in adults but not yet in pediatric patients. We evaluated a cohort of pediatric adrenocortical neoplasms to assess the applicability of AFIP/Wieneke criteria and the recently introduced Helsinki score and reticulin algorithm in predicting clinical outcomes. A tumor was considered 'clinically aggressive' in the presence of any of the following: metastases, recurrence, progressive disease, or death due to disease. Cases without any such event were considered 'clinically good'. Event-free survival time was the duration from the date of clinical presentation to any post-operative adverse event. For overall survival analysis, the endpoint was either the last follow-up or death due to disease.Using ROC curve analysis, the obtained cut-off Helsinki score of 24 could stratify the cases into two prognostically relevant groups. Survival analysis showed significant differences in the event-free and overall survival of these two groups of patients, validating the proposed cut-off. None of the three histopathological scoring systems could predict an unfavorable outcome with 100% accuracy. All showed a sensitivity of ≥ 80%, with the reticulin algorithm achieving 100% sensitivity. The specificity and accuracy of the AFIP/Wieneke criteria were the lowest (62.5% and 73.08%, respectively). While the Helsinki score (at the cut-off score of 24) and the reticulin algorithm had similar accuracy rates (80.77%, and 80%, respectively), the specificity of the former was higher (81.25%) than the latter (68.75%). A separate analysis revealed that the Ki-67 index at a cut-off of 18% had a sensitivity of 80% and a specificity of 81.25% for predicting an unfavorable outcome.

Therapeutic potential of urine exosomes derived from rats with diabetic kidney disease.

Kidney disease is prevalent in diabetes. Urinary exosomes (uE) from animal models and patients with Diabetic nephropathy (DN) showed increased levels of miRs with reno-protective potential. We examined whether urinary loss of such miRs is associated with their reduced renal levels in DN patients. We also tested whether injecting uE can leverage kidney disease in rats. In this study (study-1) we performed microarray profiling of miRNA in uE and renal tissues in DN patients and subjects with diabetes without DN (controls). In study-2, diabetes was induced in Wistar rats by Streptozotocin (i.p. 50 mg/kg of body weight). Urinary exosomes were collected at 6th, 7th and 8th weeks, and injected back into the rats (100ug/biweekly, uE-treated n=7) via tail vein on weeks 9 and 10. Equal volume of vehicle was injected in controls (vehicle, n=7). uE from the human and rat showed the presence of exosome-specific proteins by immunoblotting. Microarray profiling revealed a set of 15 miRs having high levels in the uE, while lower in renal biopsies, from DN, compared to controls (n=5-9/group). Bioinformatic analysis also confirmed the Renoprotective potential of these miRs. Taqman qPCR confirmed the opposite regulation of miR-200c-3p and miR-24-3p in paired uE and renal biopsy samples from DN patients (n=15), relative to non-DN controls. A rise in 28 miRs levels, including miR-200c-3p, miR-24-3p, miR-30a-3p and miR-23a-3p were observed in the uE of DN rats, collected between 6th-8th weeks, relative to baseline (before diabetes induction). uE- treated DN rats had significantly reduced urine albumin-to-creatinine ratio, attenuated renal pathology, and lower miR-24-3p target fibrotic/inflammatory genes (TGF-beta, and Collagen IV), relative to vehicle treated DN rats. In uE treated rats, the renal expression of miR-24-3p, miR-30a-3p, let-7a-5p and miR-23a-3p was increased, relative to vehicle control. Patients with diabetic nephropathy had reduced renal levels, while higher uE abundance of miRs with reno-protective potential. Reverting the urinary loss of miRs by injecting uE attenuated renal pathology in diabetic rats.

Evaluation of air pollution tolerance index and anticipated performance index of selected roadside tree species in Ludhiana, India.

Air quality has deteriorated in most big cities and becoming the fifth major cause of mortality in India. Among others, vehicle gaseous emission is a major contributor. Plants have different tolerance levels, which can be identified based on Air Pollution Tolerance Index (APTI). The objectives were to study the morphological and biochemical parameters for Air Pollution Tolerance Index (APTI) of selected roadside tree species (Acacia auriculiformis, Alstonia scholaris, Chukrasia tabularis, Cassia fistula, Cassia siamea, Dalbergia sissoo, Heterophragma adenophyllum, and Putranjiva roxburghii) at control (PAU campus) and polluted sites (roadside) during summer and winter seasons. The total chlorophyll content, ascorbic acid, leaf extract pH, leaf relative water content, total soluble sugar, phenols, and carotenoids ranged from 0.59 to 4.16 mg g-1, 1.03 to 3.75 mg g-1, 3.16 to 7.04, 46.01 to 71.65%, 10.78 to 23.83 mg g-1, 0.51 to 1.35 mg -1, and 0.19 to 1.96 mg g-1, respectively. The Air Pollution Tolerance Index of the selected trees ranged between7.65 and 11.19 and followed an order of Cassia fistula > Acacia auriculiformis > Dalbergia sissoo > Alstonia scholaris > Putranjiva roxburghii > Heterophragma adenophyllum > Cassia siamea > Chukrasia tabularis. The evaluation of Anticipated Performance Index (API) categorized the trees into poor (Dalbergia sissoo and Cassia siamea), moderate (Cassia fistula), and good (Acacia auriculiformis, Alstonia scholaris, Chukrasia tabularis, Heterophragma adenophyllum, and Putranjiva roxburghii) categories.

Case 308: Van Wyk-Grumbach Syndrome.

HISTORY: An 11-year-old girl presented to the pediatric gastroenterology outpatient department of our institution with gradually increasing painless abdominal distention. The distention started 2 years earlier and was not associated with any other constitutional symptoms, vomiting, diarrhea, jaundice, hematemesis, or melaena. She reported early satiety and heaviness in the lower abdomen. The abdominal swelling was predominantly in the infraumbilical region and was soft at palpation. She was the first child of nonconsanguineous parents and had an uneventful perinatal course after a normal vaginal delivery. Her developmental milestones were normal. She had an average scholastic performance at school. There was no history of visual problems, seizures, or inappropriate behaviors. She had an early menarche 2 years previously. Her menstrual cycles were regular, and there was no abnormal vaginal discharge. Her breast development was normal (Tanner stage III), while pubic and axillary hair were absent (Tanner stage I). She was short for her age (104 cm; normal range, 120-154 cm). There was no history of short stature among her siblings or parents. Laboratory investigations were performed to measure thyroid-stimulating hormone (1354.34 µIU/mL; normal range, 0.35-5.5 µIU/mL), triiodothyronine (<2.5 ng/dL [0.0385 pmol/L]; normal range, 100-200 ng/dL [1.54-3.08 pmol/L]), thyroxine (1.35 µg/dL [17.37 nmol/L]; normal range, 5-12 µg/dL [64.35-154.44 nmol/L]), ß-human chorionic gonadotropin (<1.2 mIU/mL; normal, <5 mIU/mL), luteinizing hormone (0.08 mIU/mL; normal range, 0.1-6.0 mIU/mL), and follicle-stimulating hormone (6.93 mIU/mL; normal range, 0.3-2.0 mIU/mL) levels. Complete blood count was normal. An abdominal mass was suspected, and abdominopelvic CT was performed and followed by US; these examinations revealed multiple large cysts in both ovaries. The uterus was pubertal in shape, and endometrial thickness was 9 mm, representing normal follicular phase measurement. Serum CA-125 and inhibin levels were normal. To evaluate short stature, radiographs of the hand and pelvis were obtained as part of a limited skeletal survey, keeping in mind the possible skeletal changes associated with hypothyroidism. In view of the hypothyroidism, US of the neck was also performed. Treatment was started based on the clinical and radiologic parameters, and the child's condition improved with medical treatment.

Adrenocortical Neoplasms in Children: Treatment and Outcomes.

Background: Adrenocortical tumors are rare tumors in children with a paucity of outcome data, especially in a resource-challenged setting. Materials and Methods: A retrospective study was conducted to evaluate the presentation, management, and outcomes of children with adrenocortical tumors who presented to our institute from January 1992 to December 2019. Results: During the study period, 28 children were included. Adenoma was present in nine children and the remaining 19 children had adrenocortical carcinoma. The median age of presentation was 48 months. Nearly half of the children with carcinomas presented with a mass compared to only 10% adenomas (P = 0.049). Virilization was present in 60% of the patients and in most cases was associated with Cushingoid features. Three children (15.7%) had metastasis at presentation. All children underwent surgical excision with a spill in 6 and gross residue in two patients. Recurrence was observed in five patients after a mean duration of 11.8 months. The 4-year overall survival and event-free survival were 100% in patients with adenomas compared to 75% and 44%, respectively, in carcinoma. Children who underwent complete surgical excision without any spill had a relatively favorable outcome. Conclusion: Adrenocortical tumors are uncommon tumors in children. Adenomas have a favorable outcome. There was no disease-free survival in incompletely resected or metastatic tumors. Tumor spill may also have an adverse outcome in completely resected tumors.

Case 308.

HISTORY: An 11-year-old girl presented to the pediatric gastroenterology outpatient department of our institution with gradually increasing painless abdominal distention. The distention started 2 years earlier and was not associated with any other constitutional symptoms, vomiting, diarrhea, jaundice, hematemesis, or melaena. She reported early satiety and heaviness in the lower abdomen. The abdominal swelling was predominantly in the infraumbilical region and was soft at palpation. She was the first child of nonconsanguineous parents and had an uneventful perinatal course after a normal vaginal delivery. Her developmental milestones were normal. She had an average scholastic performance at school. There was no history of visual problems, seizures, or inappropriate behaviors. She had an early menarche 2 years previously. Her menstrual cycles were regular, and there was no abnormal vaginal discharge. Her breast development was normal (Tanner stage III), while pubic and axillary hair were absent (Tanner stage I). She was short for her age (104 cm; normal range, 120-154 cm). There was no history of short stature among her siblings or parents.

Complete blood count was normal. An abdominal mass was suspected, and abdominopelvic CT was performed and followed by US; these examinations revealed multiple large cysts in both ovaries (Figs 1, 2A, 2B). The uterus was pubertal in shape, and endometrial thickness was 9 mm, representing normal follicular phase measurement. Serum CA-125 and inhibin levels were normal. To evaluate short stature, radiographs of the hand (Fig 3) and pelvis (Fig 3B) were obtained as part of a limited skeletal survey, keeping in mind the possible skeletal changes associated with hypothyroidism. In view of the hypothyroidism, US of neck was also performed (Fig 4). Treatment was started based on the clinical and radiologic parameters, and the child's condition improved with medical treatment.

A Case of Neonatal Severe Hyperparathyroidism: Challenges in Management.

Neonatal severe hyperparathyroidism is a rare disorder arising from inherited defects in the calcium sensing receptor (CaSR) that presents early in life with severe hypercalcemia, failure to thrive, and developmental retardation. The authors describe an infant with neonatal severe hyperparathyroidism due to homozygous CaSR gene mutation presenting with recurrent episodes of severe hypercalcemia, growth retardation, and developmental delay. Medical management served as an effective bridge therapy to surgery. Total parathyroidectomy with right hemithyroidectomy was performed at 7 mo of age and resulted in successful cure and normalization of growth and developmental milestones. Timely medical and surgical management can help prevent mortality and morbidity in the form of neurodevelopmental sequelae. Life-long monitoring and treatment is mandatory for the resultant hypoparathyroidism.

Development of RNA-Based Assay for Rapid Detection of SARS-CoV-2 in Clinical Samples.

INTRODUCTION: The ongoing spread of pandemic coronavirus disease-19 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is of growing concern. Rapid diagnosis and management of SARS-CoV-2 are crucial for controlling the outbreak in the community. Here, we report the development of a first rapid-colorimetric assay capable of detecting SARS-CoV-2 in the human nasopharyngeal RNA sample in less than 30 min. METHOD: We utilized a nanomaterial-based optical sensing platform to detect RNA-dependent RNA polymerase gene of SARS-CoV-2, where the formation of oligo probe-target hybrid led to salt-induced aggregation and change in gold-colloid color from pink to blue visibility range. Accordingly, we found a change in colloid color from pink to blue in assay containing nasopharyngeal RNA sample from the subject with clinically diagnosed COVID-19. The colloid retained pink color when the test includes samples from COVID-19 negative subjects or human papillomavirus-infected women. RESULTS: The results were validated using nasopharyngeal RNA samples from positive COVID-19 subjects (n = 136). Using real-time polymerase chain reaction as gold standard, the assay was found to have 85.29% sensitivity and 94.12% specificity. The optimized method has detection limit as little as 0.5 ng of SARS-CoV-2 RNA. CONCLUSION: We found that the developed assay rapidly detects SARS-CoV-2 RNA in clinical samples in a cost-effective manner and would be useful in pandemic management by facilitating mass screening.

Molecular Characterization and Management of Congenital Hyperinsulinism: A Tertiary Centre Experience.

BACKGROUND: There is limited data from India regarding medical management of congenital hyperinsulinism (CHI). OBJECTIVE: To study the molecular diagnosis, medical management and outcomes of children with CHI. STUDY DESIGN: Ambispective. PARTICIPANTS: Children with CHI admitted in from December, 2011 till March, 2020 at a tertiary care referral hospital. OUTCOMES: Clinical and genetic profile, treatment, and response. RESULTS: 42 children with a median age of 3 days (range 1 day to 6 years) were enrolled, of which 23 (54.7%) were diazoxide-responsive. Mutations were identified in 28 out of 41 (68.2%) patients. The commonest gene affected was ABCC8 in 22 patients. The pathogenic variant c.331G>A in ABCC8 gene was identified in 6 unrelated cases from one community. Good response to daily octreotide was seen in 13 of the 19 (68.4%) diazoxide-unresponsive patients. Monthly long-acting octreotide was initiated and daily octreotide could be stopped or tapered in 9 patients. Sirolimus was tried with variable response in 6 patients but was discontinued in 5 due to adverse effects. Four patients had focal CHI, of which one underwent partial pancreatic resection. The disease severity reduced with age and neurodevelopment was good in the patients with identifiable genetic defects who were optimally managed. CONCLUSIONS: Medical management of CHI is effective, if compliance can be ensured, with good quality of life and neurological outcomes.
