Key Clinical MessageSubcutaneous fat necrosis (SCFN) is a rare fat tissue inflammation of the newborn. Risk factors include cord prolapse, perinatal asphyxia, therapeutic hypothermia, meconium aspiration, and sepsis. When present, hypercalcemia comes with lethargy, hypotonia, irritability, vomiting, polyuria, polydipsia, constipation, and dehydration. Kidney injury must be avoided. SCFN is often completely autoresolutive.

• Oral paracetamol has been judged as effective as oral ibuprofen for PDA closure in the preterm. • To date, only a handful of non-randomized studies exist to support the effectiveness of i.v. paracetamol in PDA closure. What is New: • Our observations confirm the clinical efficacy of i.v. paracetamol for PDA closure in a very low birth weight (VLBW)/extremely low birth weight (ELBW) preterm population. • Gestational age and CRIB score emerge as independent predictors of PDA closure.

Despite the fact that sheep are a widely used animal model in cardiovascular research, reference values for transthoracic echocardiography in normal growing animals are not available. Eight healthy female lambs underwent two-dimensional, M-mode and pulsed wave Doppler echocardiographic examination at 100 days of age and every three months thereafter over a 12-month period. The study was conducted under sedation with midazolam, butorphanol and constant rate infusion of intravenous propofol. Their growth phase was completed at about one year of age. All the echocardiographic parameters considered were significantly correlated with body weight and age class except for the left ventricular systolic and diastolic diameters. Functional indices were not correlated to body weight or age except for the E-point to septal separation distance (EPSS). Doppler-derived parameters were not influenced by independent variables. Transthoracic echocardiography can be considered an applicable method for cardiovascular research using a growing lamb animal model after appropriate adjustments for age and body size.

A 4-year-old girl with clinical and laboratory signs of Kawasaki disease (KD) was hospitalized and given intravenous immunoglobulin plus aspirin therapy, with rapid defervescence and clinical improvement, and was discharged 48 hours after admission. At the time of her follow-up echocardiography on day 14, orange-brown pigmentation of the nail beds was noticed and confirmed with dermoscopy. No clear association between KD and orange-brown chromonychia has been demonstrated, although reports and case series suggest a possible link between these two entities. We suggest that this particular finding might be encompassed in late (subacute) changes of extremities as part of KD diagnostic criteria.

Infantile Hemangiomas (IH) are the most common benign tumor of infancy, occurring in over 10% of newborns. The head and neck is the most frequently affected area (60%), and the scalp is a typical site for such large lesions. Scalp-IHs are usually focal lesions that can be both disfiguring and may lead to complications such as ulceration and bleeding. We describe a case of a 30-months old female who presented a large scalp-IH at birth that rapidly grew in the first year of life. Topical and systemic treatments (with timolol ointment and oral propranolol, respectively) were not effective in reducing dimensions of the hemangioma. After vascular imaging study, the patient underwent surgical resection of the IH and primary closure with excellent cosmetic outcome. When medical therapy is ineffective or cosmetic and functional integrity is threatened, early surgery allows to completely removing large scalp-IHs, with good cosmetic results.

BackgroundPre-delivery maternal electrolyte derangements may reflect themselves in the newborn, since placental homeostasis determines electrolyte equilibrium between mother and fetus.Case presentationA term newborn, transferred to our Neonatal Intensive Care Unit 1 h after birth for an apnoea episode, presented with initially left-sided, and subsequently generalized tonic-clonic seizures due to severe hyponatremia (119 mmol/L). Seizures rapidly ceased after electrolyte correction plus a phenobarbital bolus. Deep hyponatremia was also detected in the mother (123 mmol/L).ConclusionsAs placental homeostasis determines electrolytes equilibrium between mother and fetus, obstetrics and neonatologists should be aware that any maternal dyselectrolytemia will reflect itself in the newborn; hence, it is fundamental to detect possible maternal electrolyte imbalances before delivery, in order to be prepared to timely correction of electrolyte derangements in the newborn.
