RESUMEN
The immaturity and vulnerability of the skin and epidermal barrier function and the frequent iatrogenic complications following diagnostic and therapeutic procedures are often associated with skin manifestations in infants in neonatal intensive care units (NICUs). The aim of the current study was to investigate dermatologic disorders in neonates in our NICU. A prospective cohort study was conducted in the NICU at the Department of Pediatrics at the University of Szeged between January 2012 and January 2013. All full- and preterm infants hospitalized in the NICU underwent whole-body skin examinations and all dermatologic disorders and treatment modalities were recorded. Eighty-nine dermatologic conditions were detected in 64 of the 211 neonates admitted to the NICU. A wide variety of clinical symptoms accompanied these conditions in these preterm and severely ill full-term infants. A considerable proportion of the disorders that were seen resulted from the immaturity of the skin and various iatrogenic complications. Dermatologic disorders are frequent in neonates requiring intensive care. Prevention, early detection, and optimal treatment of these disorders with modern, standardized skin care management strategies can result in significant improvements in barrier function and in the integrity of the skin, increasing the overall efficacy of neonatal intensive care.

Neonatal infections may be caused by various microorganisms, but as far as we are aware, Acinetobacter ursingii has not yet been reported in connection with nosocomial infections of premature infants. During 2 months, 3 premature babies were treated with nosocomial infection caused by A. ursingii at the same ward, and on the basis of molecular typing results the same strain was responsible for all of these cases. Traditional biochemical methods and automatic identification systems failed to identify this bacterium on the species level, and only 16S rDNA sequencing gave acceptable species identifications. The isolated strains proved to be susceptible to all of the tested antimicrobials, including ampicillin/sulbactam, doxycyclin, netilmicin, ciprofloxacin, piperacillin/tazobactam, ceftazidime, imipenem, meropenem, trimethoprim/sulfametoxazole, gentamicin, tobramycin, amikacin, and levofloxacin according to the CLSI standard. In spite of the environmental screening, the source of the infection could not be clarified. One of 3 neonates died, the others recovered and were discharged home after several months of hospitalization.

Oxidative stress is known to play an important role in the pathogenesis of certain severe illnesses in preterm infants. The enzyme heme oxygenase-1 (HO-1) participates in cytoprotection against oxygen radical injury. We have previously described the role of HO-1 in physiologic adaptation by demonstrating the induction of HO-1 in healthy mature neonates and asymptomatic preterm infants. Our current aim was to investigate the HO-1 expression in preterm infants with respiratory distress syndrome (RDS). We collected venous blood samples from 28 preterm infants with RDS on the 1st, 3rd and 5th days after birth. The HO-1 mRNA expression was determined by means of a competitive reverse transcriptase PCR technique, and a quantitative blood count was performed on the residual blood sample. A significant increase in HO-1 expression was found in the preterm infants with RDS as compared with both the healthy mature and the asymptomatic premature groups. The elevation was approximately eight-fold. The platelet count displayed a significant negative association with the HO-1 expression, and in the RDS prematures with thrombocytopenia the HO-1 induction was significantly greater than in those with a normal platelet count. In conclusion, the RDS of prematures is accompanied by an elevated HO-1 expression during the first 5 days of life, consistent with the inflammatory and oxidative characteristics of the disease.

BACKGROUND: Extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria are highly dangerous to neonates. At our Neonatal Intensive Care Unit (NICU), the presence of these bacteria became so threatening in 2011 that immediate intervention was required. METHODS: This study was conducted during a nearly two-year period consisting of three phases: retrospective (9 months), educational (3 months) and prospective (9 months). Based on retrospective data analysis, a complex management plan was devised involving the introduction of the INSURE protocol, changes to the antibiotic regimen, microbiological screening at short intervals, progressive feeding, a safer bathing protocol, staff hand hygiene training and continuous monitoring of the number of newly infected and newly colonized patients. During these intervals, a total of 355 patients were monitored. RESULTS: Both ESBL-producing Enterobacter cloaceae and Klebsiella pneumoniae were found (in both patients and environmental samples). In the prospective period a significant reduction could be seen in the average number of both colonized (26/167 patients; P=0.029) and infected (3/167 patients; P=0.033) patients compared to data from the retrospective period regarding colonized (72/188 patients) and infected (9/188 patients) patients. There was a decrease in the average number of patient-days (from 343.72 to 292.44 days per months), though this difference is not significant (P=0.058). During the prospective period, indirect hand hygiene compliance showed a significant increase (from the previous 26.02 to 33.6 hand hygiene procedures per patient per hospital day, P<0.001). CONCLUSION: Colonizations and infections were rolled back successfully in a multi-step effort that required an interdisciplinary approach.

BACKGROUND: Most of the skin disorders that occur in neonatal intensive care units are due in part to the immaturity and vulnerability of the neonatal skin. Various iatrogenic diagnostic and therapeutic procedures are also conducive to iatrogenic damage. This study was to review the neonates admitted to our neonatal intensive care unit who needed wound management, and to assess the most common skin injuries and wounds, and their aetiology. METHODS: Data were extracted from medical records of neonates who needed wound management in our Neonatal Intensive Care Unit between January 31, 2012 and January 31, 2013. Information about gestational age, sex, birth weight, area of involvement, wound aetiology, and therapy were collected. RESULTS: Among the 211 neonates observed, wound management was required in 10 cases of diaper dermatitis, 7 epidermal stripping, 6 extravasation injuries, 5 pressure ulcers, 1 surgical wound and infection, 1 thermal burn, and 5 other lesions. CONCLUSIONS: International guidelines in neonatal wound care practice are not available, and further research concerns are clearly needed. Dressings and antiseptic agents should be chosen with great care for application to neonates, with particular attention to the prevention of adverse events in this sensitive population. Team work among dermatologists, neonatologists and nurses is crucial for the successful treatment of neonates.

We report three patients with early neonatal infections. All patients had respiratory tract involvement with increased inflammation markers. Chryseobacterium gleum was cultured from the stomach content aspirated on arrival at the Neonatal intensive Care Unit and it was identified with the help of a Microflex™ MALDI Biotyper mass spectrometer (Bruker-Daltonik, Fremont, CA). Recovery could be achieved with ciprofloxacin treatment. We consider our cases a possible new clinical presentation of a rare human pathogen.

Wound care in neonates demands special awareness of the anatomical and physiological characteristics of their skin, and the danger of adverse mechanical and toxicological events. Here, we present the case of a full-term neonate born with myelomeningocele. Following the closing surgery on the 3rd day of postuterine life, the operated region became inflamed, the sutures opened and a necrotic discharging ulcer developed. Besides parenteral antibiotic treatment based on the microbiological findings, intelligent hydrofiber dressings were applied to the wound with regard to the special characteristics of wound care in neonates. After 72 days, the ulcer had healed with a small residual scar, and the infant is currently demonstrating normal physical and mental development.
