Emergency retrieval of embolised patent ductus arteriosus device from the right pulmonary artery.

Percutaneous closure of patent ductus arteriosus using a duct occluder has become standard of care in its management especially in children more than 6 months of age, weighing more than 6 kg but device embolisation is a potential life-threatening complication and may require immediate open-heart surgery. We describe a case of successful surgical management of a patient in early childhood, in which device has embolised deep into the right pulmonary artery.

Effects of umbilical cord milking versus delayed cord clamping on systemic blood flow in intrauterine growth-restricted neonates: A randomized controlled trial.

Recommendations for umbilical cord management in intrauterine growth-restricted (IUGR) neonates are lacking. The present randomized controlled trial compared hemodynamic effects of umbilical cord milking (UCM) with delayed cord clamping (DCC) in IUGR neonates > 28 weeks of gestation, not requiring resuscitation. One hundred seventy IUGR neonates were randomly allocated to intact UCM (4 times squeezing of 20 cm intact cord; n = 85) or DCC (cord clamping after 60 s; n = 85) immediately after delivery. The primary outcome variable was superior vena cava (SVC) blood flow at 24 ± 2 h. Secondary outcomes assessed were anterior cerebral artery (ACA) and superior mesenteric artery (SMA) blood flow indices, right ventricular output (RVO), regional cerebral oxygen saturation (CrSO2) and venous hematocrit at 24 ± 2 h, peak total serum bilirubin (TSB), incidences of in-hospital complications, need and duration of respiratory support, and hospital stay. SVC flow was significantly higher in UCM compared to DCC (111.95 ± 33.54 and 99.49 ± 31.96 mL/kg/min, in UCM and DCC groups, respectively; p < 0.05). RVO and ACA/SMA blood flow indices were comparable whereas CrSO2 was significantly higher in UCM group. Incidences of polycythemia and jaundice requiring phototherapy were similar despite significantly higher venous hematocrit and peak TSB in UCM group. The need for non-invasive respiratory support was significantly higher in UCM group though the need and duration of mechanical ventilation and other outcomes were comparable. CONCLUSIONS:  UCM significantly increases SVC flow, venous hematocrit, and CrSO2 compared to DCC in IUGR neonates without any difference in other hemodynamic parameters and incidences of polycythemia and jaundice requiring phototherapy; however, the need for non-invasive respiratory support was higher with UCM. TRIAL REGISTRATION: Clinical trial registry of India (CTRI/2021/03/031864). WHAT IS KNOWN: • Umbilical cord milking (UCM) increases superior vena cava blood flow (SVC flow) and hematocrit without increasing the risk of symptomatic polycythemia and jaundice requiring phototherapy in preterm neonates compared to delayed cord clamping (DCC). • An association between UCM and intraventricular hemorrhage in preterm neonates < 28 weeks of gestation is still being investigated. WHAT IS NEW: • Placental transfusion by UCM compared to DCC increases SVC flow, regional cerebral oxygenation, and hematocrit without increasing the incidence of symptomatic polycythemia and jaundice requiring phototherapy in intrauterine growth-restricted neonates. • UCM also increases the need for non-invasive respiratory support compared to DCC.

Clinico-Microbiological Profile and Clinical Predictor of Urinary Tract Infection in Children: A Single-Center Study From Himalayan Foothills.

BACKGROUND:  Urinary tract infection (UTI) in children is one of the commonest bacterial infections seen in the pediatric population. Clinical presentation ranges from fever with or without focus and isolation of microbiological agents streamline the treatment. Moreover, local/regional microbial profiles are helpful in antibiotic selection, we conducted a study to assess the prevalence of urine culture positivity in a suspected case of UTI. In addition, antibiotic susceptibility patterns and ultrasonography (USG) finding in culture-positive patients were also studied. METHODS AND MATERIALS: It is a prospective observational study comprising symptomatic children aged one month to 18 years presenting to the outpatient department (OPD), inpatient department (IPD), and the emergency department of Pediatrics with UTI during the period of September 2019 to September 2020. The recorded variables were demographic, clinical presentation, anthropometry, physical examination, blood biochemistry, and outcome. Urine samples were collected and processed as per standard protocols. USG was done for all culture-positive children. Data were presented as frequency, mean (SD) and parametric and non-parametric data were analyzed by Wilcoxon-Mann-Whitney U Test, Chi-Squared Test, or Fisher's Exact Test.  Results: Of the total 354 children, 202 (57.1%) were male and the prevalence of UTI was 64 (18.1%). E. coli (70.3%) was the commonest isolated organism followed by Klebsiella spp (15.6%) and Pseudomonas spp (7%) respectively. The mean (SD) age (months) of presentation of symptoms was significantly lower in culture-positive children as compared to [ 83.49 (58.96) vs 110.10 (58.60); p=0.001] culture-negative children. Fever (96.6%) followed by dysuria (20.1%) were the most common symptoms presented for UTI however dysuria (p=0.003), pus cells (p<0.0001), and RBCs (p=0.002) were significantly present in culture positive children. This study shows increased resistance to third generation of cephalosporins. This study revealed significant differences among various groups (organism growth in positive culture) and the Antibiotic susceptibility test (AST) with a p-value of <0.001.  Conclusion: The prevalence of culture-positive UTI was similar to the reported literature and the presence of fever, dysuria, pus cells, and RBC in urine were commonly observed in the lower age group. Amikacin can be used in suspected UTIs with cephalosporin as empirical antibiotics in the Himalayan Foothills region.

Megaloblastic wobbliness: A reversible neurological condition.

BACKGROUND: Vitamin B12 deficiency has been associated with a very wide spectrum of neurologic manifestations and the majority of cases occur in infants, pregnant women, and elderly people. In children, common neurological complications include neuropathy, neuropsychiatric features, infantile tremor syndrome, developmental delay, cognitive decline, spastic paraparesis due to subacute combined degeneration of cord, seizures, encephalopathy, extrapyramidal features, and neuropathy. Vitamin B12 is known to cause sensory ataxia, along with impaired position and vibration sense, as well as variable spasticity, as a part of subacute combined degeneration of the spinal cord. However, only a few cases of isolated cerebellar ataxia caused by vitamin B12 deficiency have been reported in published literature. METHODS AND RESULTS: We are reporting a case of isolated cerebellar ataxia progressing over months in a 13-year-old boy. He also had associated knuckle hyperpigmentation, megaloblastic anemia and his magnetic resonance imaging of the brain was normal. Complete blood count showed hemoglobin of 8.6 gm/dl and peripheral smear showed macrovalocytes and few hypersegmented neutrophils. Serum vitamin B12 level was low (134 pg/mL). He was started on daily intramuscular vitamin B12 supplementation and he showed a favorable response after the first week. CONCLUSIONS: Clinicians need to consider vitamin B12 deficiency as one of the rare etiological possibilities in children presenting with isolated subacute onset/chronic ataxia, as supplementation of this vitamin is likely to cause a complete reversal of ataxia in such children.

Heart Failure in Tetralogy of Fallot due to Associated Hypertrophic Obstructive Cardiomyopathy: A Lesson to Learn.

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Heart failure (HF) in a case of uncomplicated TOF is uncommon but can occur under special circumstances. TOF associated with hypertrophic obstructive cardiomyopathy (HOCM) is a very rare combination of anomalies, and very few cases have been reported in the literature. Here, we report the case of a 2-month-old male infant who presented to us with central cyanosis and features of HF. He was worked up and found to have TOF with HOCM and advised surgical correction. Hence, we propose that HOCM is also one factor which can precipitate HF in a patient of TOF along with the classical causes mentioned in the literature. Furthermore, the left ventricular outflow tract obstruction of HOCM in a patient of TOF has an inverse relation with the degree of cyanosis.

Repair of intracardiac total anomalous pulmonary venous return.

Total anomalous pulmonary venous return is an uncommon congenital anomaly of the pulmonary venous system.  Excision of the common wall between the atrial septum and the coronary sinus and closure with a single patch is a popularly used technique to repair cardiac total anomalous pulmonary venous return. We have used the same approach in our patient: Our tutorial shows a simple method to divert pulmonary venous return into the mitral valve without causing damage to the internodal pathways.  Marking the coronary sinus is highlighted because using that landmark to locate the atrioventricular node is no longer possible after the common wall is cut.

Case Report: Dengue Virus-Triggered Parkinsonism in an Adolescent.

Dengue fever continues to be an important cause of morbidity and mortality in tropical and subtropical countries. A wide range of neurological manifestations including dengue encephalopathy, Guillain-Barre syndrome, acute disseminated encephalomyelitis, transverse myelitis, cranial nerve palsies, and myositis have been reported following dengue infection. But parkinsonism secondary to dengue virus infection is uncommon, with only three published case reports in adults and one in children. We describe a 13-year-old pre-morbidly normal boy, who presented with bradykinesia, bradyphonia, mask-like facies, and cogwheel rigidity while recovering from uncomplicated DF. He responded favorably to levodopa/carbidopa supplementation and had resolution of symptoms over the next 2 weeks. We also did a comparative review of all published cases of dengue-induced parkinsonism. Post-dengue, parkinsonism is uncommon, and treating clinicians should be aware of this uncommon but treatable neurological complication of a common arboviral infection.

Pulmonary Embolism in Children: A Case Series.

BACKGROUND: Pulmonary embolism (PE) is a life-threatening event with a mortality of ~10%. It is relatively uncommon in children and literature regarding the condition is sparse. In adults, the classical clinical presentation is with pleuritic chest pain, hemoptysis, and dyspnea, whereas in children, the presentation is often nonspecific. MATERIALS AND METHODS: Clinical features, risk factors, and outcome of children with PE presenting to our unit between December, 19 and March, 2020 were recorded. RESULTS: Four children [mean age: 10 (6-16) years, 3 females], all presenting with tachycardia and dyspnea were diagnosed with PE. Different risk factors such as deep vein thrombosis, nephrotic syndrome, softtissue infection, and infective endocarditis (IE) were identified in all patients. One child died while others responded to anticoagulation. CONCLUSION: We aim to highlight the importance of timely recognition of PE in children with known risk factors for the same. Early recognition and timely treatment of PE are critical to save lives. HOW TO CITE THIS ARTICLE: Agrawal S, Shrivastava Y, Bolia R, Panda PK, Sharawat IK, Bhat NK.

Familial 7q11.23 duplication with variable phenotype.

Chromosomal microdeletions and microduplications are known to cause variable clinical features ranging from apparently normal phenotype to intellectual disability, multiple congenital anomalies, and/or other variable clinical features. 7q11.23 region deletion is the cause for Williams-Beuren syndrome and duplication of same region 7q11.23 causes distinguishable clinical phenotype. Familial inheritance is known for both microdeletion and microduplication of 7q11.23 region. Here, we report a patient of paternally inherited 7q11.23 microduplication with developmental delay, macrocephaly, and structural brain malformations.
