Lung hypoplasia was the most common congenital lung malformation in our setup. Detection of malformation during antenatal period was poor. Age of diagnosis and surgical intervention is often delayed. Regular follow up and definitive and/or supportive management decreased the morbidity.

There is a paucity of data on use of dexmedetomidine as a sedative agent in mechanically ventilated children.

To compare the efficacy of dexmedetomidine and midazolam for sedation in mechanically ventilated children aged 1 month - 15 years. Secondary objectives were to compare the need for top-up doses of fentanyl and paralytic agents, duration of mechanical ventilation, ICU stay and hospital stay, and adverse events.

Open label, non-inferiority, randomized controlled trial.

PICU of a tertiary care teaching hospital in India.

Consecutive children aged 1 month to 15 years who were mechanically ventilated.

Children were randomized to either dexmedeto-midine or midazolam and the doses were titrated to maintain target sedation score of 4 or 5 as measured by Penn State Children Hospital Sedation algorithm.

The percentage of time spent in level 4 or 5 of Penn State Children Hospital sedation algorithm for ventilated children.

49 children were randomized (24 to 'midazolam group' and 25 to 'dexmedetomidine group'). There was no difference in the percentage of time spent in the targeted sedation between the groups [midazolam 67.3% (18.8) vs. dexmedetomidine 56.3 %. (28.6); P=0.12]. The absolute difference in the percentage of time spent was -10.9% [SE (95% CI) 7.05 (-25.15 to 3.25)]. The lower end of 95% CI for the difference breached the non-inferiority limit of -20%. Number of fentanyl boluses, duration of mechanical ventilation, ICU stay, and hospital stay were similar. Four (17.4%) children in dexmedetomidine group developed persistent bradycardia.

Non-inferiority of dexmedetomidine compared to midazolam for sedation in children on mechanical ventilation could not be established.

Some studies have demonstrated the neuroprotective effects of dexmedetomidine (DEX). Here, alterations in nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy were investigated as the possible causes of DEX's neuroprotection of HT22 cells against methotrexate (MTX)-induced neurotoxicity. We used various concentrations of DEX and NCOA4-siRNA to treat MTX-induced neurotoxicity and inflammation in HT22 cells. The biomarkers of HT22 cells viability, apoptosis and inflammatory were tested. The expression of ferritinophagy markers were detected in the HT22 cells by using western blot and Immunofluorescence. We found that 10 and 50 ng/mL of DEX alleviated MTX-induced hippocampal neuronal inflammatory injuries. Meanwhile, DEX also reversed MTX-induced iron and ROS overproduction. Increasing DEX concentrations caused significant falls in the expression of ferritin heavy chain 1 (FTH1). DEX also increased vital ferritinophagy markers, NCOA4 and LC3II. NCOA4-siRNA transfection annulled the neuroprotective effects of DEX on MTX-induced inflammation in HT22 cells. Additionally, because NCOA4-siRNA disrupted ferritinophagy, DEX's inhibitory impact on MTX-induced iron and ROS overproduction in HT22 cells was also annihilated. DEX weakened MTX-provoked neurontoxicity in HT22 cells, possibly by improving NCOA4-mediated ferritinophagy. Our discoveries present further mechanisms for understanding the protective effects of DEX against MTX-induced cognitive impairment.
The objective was to investigate the changes in urology practice during coronavirus disease 2019 (COVID-19) pandemic with a perspective from our experience with severe acute respiratory syndrome (SARS) in 2003.

Institutional data from all urology centres in the Hong Kong public sector during the COVID-19 pandemic (1 Feb 2020-31 Mar 2020) and a non-COVID-19 control period (1 Feb 2019-31 Mar 2019) were acquired. An online anonymous questionnaire was used to gauge the impact of COVID-19 on resident training. The clinical output of tertiary centres was compared with data from the SARS period.

The numbers of operating sessions, clinic attendance, cystoscopy sessions, prostate biopsy, and shockwave lithotripsy sessions were reduced by 40.5%, 28.5%, 49.6%, 44.8%, and 38.5%, respectively, across all the centres reviewed. The mean numbers of operating sessions before and during the COVID-19 pandemic were 85.1±30.3 and 50.6±25.7, respectively (P=0.005). All centres gave priority to cancer-related surgeries. Benign prostatic hyperplasia-related surgery (39.1%) and ureteric stone surgery (25.5%) were the most commonly delayed surgeries. The degree of reduction in urology services was less than that during SARS (47.2%, 55.3%, and 70.5% for operating sessions, cystoscopy, and biopsy, respectively). Oseltamivir The mean numbers of operations performed by residents before and during the COVID-19 pandemic were 75.4±48.0 and 34.9±17.2, respectively (P=0.002).

A comprehensive review of urology practice during the COVID-19 pandemic revealed changes in every aspect of practice.
A comprehensive review of urology practice during the COVID-19 pandemic revealed changes in every aspect of practice.Neonatal hemochromatosis (NH), one of the most common causes of liver failure in the neonate, often causes fetal loss or death during the neonatal period. Most cases are thought to be due to gestational alloimmune disease; however, other rare causes have been reported. NH is generally considered congenital and familial but not heritable. We present an infant diagnosed with NH whose clinical course differed significantly from that of most NH cases at 11 months of age he had normal levels of liver enzymes, ferritin, and bilirubin, and normal neurodevelopment. This term male infant was born with a history of intrauterine growth restriction, oligohydramnios, and pericardial effusion. On day of life 1, he had hyperbilirubinemia and transaminitis; on day of life 3, ferritin was elevated; and on day of life 9, an MRI revealed iron deposits in the liver and renal cortex. Phenotypic features prompted a genetics consult. Whole-exome sequencing revealed a variant in the phosphatidylinositol glycan biosynthesis class A protein (PIGA) gene.
