Neonatal Burns - A Romanian Experience From A Tertiary Care Burn Unit.

Burns in neonates is a unique pathology that poses management challenges, as, besides treating the burn injury, the medical team needs to be familiar with the unique physiology of the newborn. This study aimed to review our center's experience with the management of neonatal burns. A 7-year retrospective study of neonatal burns managed at a tertiary national referral unit in Bucharest, Romania, was performed. Patients were divided into two groups, preterm and term, based on gestational age. Collected data included demographics, treatment, complications and follow-up. Our center managed 13 neonates with burns (5 term and 8 preterm), with a mean age at injury of 8.6 days. All neonatal burns were thermal injuries. For preterm babies, all burns were iatrogenic, consisting of victims of a fire in a Maternity Hospital, while for the term group only one was iatrogenic. Burns were more extensive in the premature group (65% vs. 20% mean TBSA, p=0.0001). All premature patients had associated inhalation injuries. Surgical treatment was indicated for two term patients. Survival rate was 77% and was negatively influenced by inhalation injury, burn shock and TBSA >50%. In conclusion, the majority of hospitalized neonatal burns in Romania were the result of a fire disaster secondary to an infrastructure deficiency. Their management is complex, posing specific challenges, and needs to be led by a multidisciplinary team that can ensure an individualized continuum of acute burn care and recovery.

Les brûlures du nouveau- né (NN) posent une problème physiopathologique spécifique, tenant non seulement aux conséquences de la brûlure mais aussi à la physiologie particulière du NN. Cet article décrit notre expérience. Il s'agit d'une étude rétrospective reprenant les 13 NN pris en charge dans un CTB de référence de Bucarest, pour une brûlure survenue en moyenne à 8,6J. Les patients ont été répartis entres prématurés (P,8) et à terme (T,5). Toutes les brûlures étaient thermiques, toutes iatrogènes dans le groupe P, consécutives à un incendie à la maternité quand une seule était iatrogène dans le groupe T. Elles étaient plus étendues dans le groupe P (65% SCT) que dans le groupe T (20%, p= 0,0001). Tous les P avaient des lésions d'inhalation. Une greffe a été nécessaire pour 2 T. La mortalité était de 23%, influencée par la surface brûlée, l'inhalation et une surface atteinte >50 %. En conclusion, la plupart des brûlures de NN roumains ayant nécessité une hospitalisation étaient dues à l'incendie d'une maternité à l'architecture déficiente. Leur prise en charge est complexe et spécifique, ce qui nécessite une équipe entraînée, à même de proposer des soins adaptés, de la phase aiguë à la rééducation.

Etiology Of Neonatal Burns: A Systematic Review.

Burns in neonates are a rare pathology with a significant impact on the patient, the family and the healthcare system. At present, scarce information exists on the etiology of this type of injury. A comprehensive worldwide literature review of all publications, including our personal case series, was conducted in order to analyse the etiology of neonatal burns and summarize the available evidence. A total of 41 publications were identified in the last 4 decades, comprising of 105 cases from 20 countries, thus confirming that neonatal burns are, indeed, a rare pathology. All types of burns were recorded in neonates, the most frequent being contact burns, followed by flames and scalds. Almost 60% of burns occurred in a hospital setting due to human factors, malfunctioning devices, or hospital infrastructure deficiency. Compared to domestic burns, iatrogenic injuries occurred at an earlier age (5.4±9.1 days vs. 15.7±9.8 days, p<0.0001) and in neonates with significantly smaller weights (2102.7±1350g vs. 3197±300.8g, p<0.0001). The number of cases was almost equally distributed between developed and developing countries, but developed countries were characterised by a significantly higher preponderance of iatrogenic burns, while in developing countries domestic burns were more frequent (p<0.0001). We believe that this systematic review outlines the potential causes of neonatal burns and provides essential information for formulating prevention strategies.

Les brûlures néonatales, rares, ont un impact important sur l'enfant, ses parents et le système de santé. Nous ne disposons de que de peu de données étiologiques à leur sujet. Nous avons de ce fait réalisé une revue bibliographique et y avons adjoint nos données personnelles. Sur les quarante dernières années, nous avons trouvé 41 publications sur les 40 dernières années, compilant 105 cas dans 20 pays, confirmant la rareté des brûlures néonatales. On trouve tous les groupes de cause, par ordre de fréquence contact, flammes et ébouillantement. Presque 60% d'entre elles surviennent en milieu hospitalier, dues à une erreur humaine, un dispositif fonctionnant mal ou un défaut structurel. Les brûlures nosocomiales surviennent plus tôt (5,4 +/-9,1 j VS 15,7 +/-9,8; p<0,0001) que les brûlures au domicile, chez des enfants de plus petit poids (2 102,7 +/-1 350 g VS 3 197 +/-300,8 g; p< 0,0001). Le nombre de cas était également répartis selon les revenus des pays, les brûlures iatrogènes étant plus fréquentes dans les pays à IDH élevé (<0,0001). Les causes que nous avons retrouvées devraient permettre le développement de stratégies de prévention.

Xanthogranulomatous pyelonephritis in a paediatric cohort (1963-2016): Outcomes from a large single-center series.

BACKGROUND: Xanthogranulomatous pyelonephritis (XGP) is an uncommon chronic destructive granulomatous inflammation of the kidney. It was first described in 1916, and is thought to affect 6/1000 cases of pyelonephritis. Its manifestations are varied, and with a limited number of cases in the literature, the optimal diagnosis and management of XGP in the paediatric cohort is still unknown. MATERIAL AND METHODS: The medical records of children who were diagnosed and treated for XGP at the current unit during the period 1963-2016, inclusive, were retrospectively reviewed. Information pertaining to each patient was recorded, including: demographic data, past medical history, clinical and biochemical characteristics, diagnostic procedures, treatment methods, histopathologic diagnosis of the removed specimen, and outcome. RESULTS: A total of 66 children with a median age of 4.84 years (range 1.1-14.81), with an M:F ratio 1.35:1 underwent nephrectomy for XGP and had a median follow-up of 7.19 years (range 0.11-17.45). The most common presentations were systemic illness (62.1%), pain (60.6%), urinary tract infections (54.5%) and an abdominal mass (39.4%); pyrexia was present in 53%. Biochemical abnormalities included anaemia (86.3%), thrombocytosis (80.3%) and hypomagnesemia (65.1%). There was an 83.3% concordance between intraoperative cultures and positive mid-stream urines. Index kidneys were significantly larger than the contralateral side (mean 1.32 cm; P = 0.002). Staging of XGP demonstrated extension beyond the kidney in 79% of kidneys. Computed tomography (CT) was performed in 11 cases (Summary figure). Dimercaptosuccinic acid (DMSA) scan showed 0-10% function in 90.47% of cases. Surgical procedures included nephrectomy (n = 63) and partial nephrectomy (n = 3). Perioperative complications included colonic resections (n = 5) and abscess formation in 18%. CONCLUSIONS: This is the largest series to date of XGP in a paediatric cohort. XGP should be included in the differential diagnosis of all children presenting with perirenal or psoas abscesses, renal masses and/or non-functioning kidneys with/or without associated urolithiasis. Clinical awareness and a high index of suspicion is required to achieve the correct pre-operative diagnosis and appropriate management.

Difficulties in the diagnostics and treatment of near-total congenital megacolon.

Near total colonic aganglionosis is one of the rarest forms of Hirschsprung's disease and until recent years it has been considered deadly. Establishing a correct diagnosis has proven to be challenging, because while the clinical and radiological features can be useful, they are not pathognomonic. Chronic intestinal obstruction and long-term parenteral nutrition dependency are associated with a high mortality risk for these patients. While there is no current consensus with regards to a superior operative method, the patients benefit from surgical techniques aimed at lengthening the intestine, as well as from intestine transplant. We report the case of a newborn baby girl who was admitted to our clinic for abdominal distension,biliary and fecaloid vomiting. With an initial suspicion of digestive tract malformation, the diagnosis of near total congenital megacolon was established with great difficulty and the infant underwent serial surgeries, ending up with an extended myotomy-myectomy (Ziegler's procedure) as a curative approach, with favorable immediate postoperative evolution.However, the patient developed sepsis and although the infection was treated accordingly, the baby's general condition kept deteriorating and exitus was recorded 77 days after admission.

Associated type IIIB and type IV multiple intestinal atresia in a pediatric patient.

Multiple intestinal atresia (MIA) is a complex congenital defect which represents a challenge for the pediatric surgeon,especially in the rare event of encountering type IIIb or apple peel atresia, which has a high mortality rate. The surgeon's aim is to preserve as much bowel length as possible, to avoid postoperative sepsis and to prevent long-term complications such as short bowel syndrome. Access to a good neonatal intensive care unit and to parenteral nutritional support is crucial in the survival of these children. We report a rare case of multiple intestinal atresia associated with an apple peel atresia, which was managed by multiple intestinal resections and anastomosis without the placement of transanastomotic tubes or stomas.

Ileocolic intussusception due to Burkitt lymphoma: a case report.

Burkitt lymphoma has many forms of clinical presentations and, in children, it is usually discovered due to the presence of an abdominal mass. This rapidly growing tumor is highly malignant, aggressive, and may cause either indirect symptoms, due to pressure phenomena or direct involvement of the bowel lumen, leading to either intestinal obstruction or intussusception. We describe the case of a 4-year-old girl who exhibited an unusual presentation of ileocolic intussusception on a Burkitt lymphoma lesion of the ileum.

Solvent interactions and protein dynamics in spin-labeled T4 lysozyme.

Aspects of T4 lysozyme dynamics and solvent interaction are investigated using atomically detailed Molecular Dynamics (MD) simulations. Two spin-labeled mutants of T4 lysozyme are analyzed (T4L-N40C and T4L-K48C), which have been found from electronic paramagnetic resonance (EPR) experiments to exhibit different mobilities at the site of spin probe attachment (N- and C-terminus of helix B, respectively). Similarities and differences in solvent distribution and diffusion around the spin label, as well as around exposed and buried residues within the protein, are discussed. The purpose is to capture possible strong interactions between the spin label (ring) and solvent molecules, which may affect EPR lineshapes. The effect of backbone motions on the water density profiles is also investigated. The focus is on the domain closure associated with the T4 lysozyme hinge-bending motion, which is analyzed by Essential Dynamics (ED). The N-terminus of helix B is found to be a "hinge" residue, which explains the high degree of flexibility and motional freedom at this site.
