Mycobacterium Species on the Cutaneous Microbiome of Very Preterm Neonates.

The neonatal skin microbiome consists of all the genomes and genetic products of microorganisms harboring on an infant's skin. Host and the microbiota develop a harmonious environment resulting in symbiosis. Any disruption of this environment could lead to pathological disease. This study was conducted to understand the neonatal skin microbiome of very preterm neonates (under 32 weeks) admitted to the Neonatal Intensive Care Unit(NICU) at a tertiary healthcare setting before and after kangaroo mother care (KMC), using next-generation sequencing (NGS). Skin swabs were collected on two different occasions and analyzed using the NGS technique after amplification via polymerase chain reaction. The results showed relative abundance for Mycobacterium tuberculosis in 83.33% and 66.67% (p = 0.29) and Mycobacteroides abscessus in 100% and 93.33% (p = 0.30) of the very preterm neonates on the skin microbiome before and after KMC, respectively as an incidental finding. The mere presence of these bacilli as commensals or as potential pathogens is alarming due to the risk of early exposure and incidence of tuberculosis from birth. These findings, in our view, are the first findings to be established in such a setting.

Acute Leukoencephalopathy with Restricted Diffusion in an Infant with Severe COVID-19 and Dengue Coinfection Progressing to West Syndrome.

COVID-19 pandemic is increasingly being recognized in infants and some develop cytokine storm mediated tissue damage. We report 5-month-old infant presenting with fever, refusal of feeds, developing altered sensorium and convulsions during the hospital course, tested positive for SARS-CoV2 RT-PCR in second week of illness. Her serology was also Dengue positive. She had features of cytokine storm and her MRI Brain suggested acute demyelinating encephalomyelitis (ADEM). She was treated with high-dose methylprednisolone followed oral prednisolone, under antibiotics cover. Infant improved gradually over 3 weeks duration following a stormy hospital course. On follow-up, infant showed delayed motor milestones with epileptic spasms and hysparrhthymia on EEG, progressing to develop secondary West syndrome. Features of acute encephalopathy, hypercytokinemia and restricted diffusion on DWI-MRI, with post-encephalopathic epilepsy, pointed to a differential of ADEM-acute leukoencephalopathy with restricted diffusion (ALERD) as the primary diagnosis; establishing ALERD as a possible neurological complication of COVID-19 infection in infants. Timeline of events. There is a demonstrable fall in the inflammatory markers with clinical improvement following the start of intravenous methylprednisolone. Epileptic spasms and developmental delay with hypsarrhthymia noted on follow-up, suggestive of secondary West syndrome.

Impact of Kangaroo Mother Care on Skin Microbiome of Very Preterm Infants - A Pilot Study.

OBJECTIVES: To test whether Kangaroo mother care (KMC) aids in transfer of favourable skin microbiome from mother to infant by comparing the microbiome composition before and after KMC. METHODS: A prospective cohort pilot study was conducted in a Level III neonatal intensive care unit (NICU) in South India, recruiting 30 preterm infants with gestation <32 wk from October 2020 through December 2020. Neonatal skin involving the area in contact with the mother during KMC i.e., axilla, chest and abdomen was swabbed at the end of first week of life, prior to initiation of KMC. The 2nd swab involving the same areas was taken following KMC for 7 d for at least 6 h a day. The swabs were analysed using Next Generation Sequencing (NGS) - 16sRNA and abundance of organisms isolated were mapped. Statistical analyses using t-test and PERMANOVA were performed to compare phyla and genera of bacterial abundance pre-KMC and post-KMC. RESULTS: KMC at phyla level increased the relative abundance of Firmicutes (p=0.52) and significantly decreased Proteobacteria (p=0.02). At species level, KMC decreased pathogenic bacterial count of Escherichia (p=0.05), while counts of S. hemolyticus (p=0.01) and S. hominis (p=.002) significantly increased post KMC. CONCLUSIONS: KMC has a potential role in altering the neonatal skin microbiota towards a more favourable microenvironment. The clinical significance of these novel findings needs to be validated with larger studies.

Ochoa Syndrome - Neurogenic Bladder with an Inverted Smile.

Ochoa or urofacial syndrome is a rare autosomal recessive syndrome with around 150 cases reported in the medical literature comprising of neurogenic bladder and facial abnormalities, culminating in obstructive uropathy and chronic kidney disease. We report a 5-year-old boy presenting to us with Stage IV chronic kidney disease with bilateral hydroureteronephrosis secondary to chronic urinary incontinence. His peculiar facial expression with a grimace while smiling suggested the diagnosis of Ochoa syndrome. He was managed conservatively for neurogenic bladder and is under follow-up. We wish to highlight this unique syndrome and the simplicity in making this syndromic diagnosis, just by appreciating abnormal facial expressions.

Exploring the Skin Mycobiome in Very Preterm babies during the early neonatal period in a Neonatal Intensive Care Unit of India.

The neonatal skin microbiome consists of all the genomes and genetic products of micro-organisms harbouring the skin of babies. Host and the microbiota develop a harmonious environment resulting in symbiosis. Any disruption of this environment could lead to pathological disease. Our study was conducted to explore the neonatal skin fungal microbiome of very preterm neonates admitted to Neonatal Intensive Care Unit at a tertiary health care setting using Next Generation Sequencing of the18S rRNA gene. The most abundant genera found in 22/30 samples were Candida followed by Bipolaris & Cladosporium on the skin microbiome of these neonates. The presence of these fungi, whether just as commensals or as potential pathogens, is currently under research, owing to the risk of early exposure and incidence of infection right from birth.
