Outbreak of Elizabethkingia meningoseptica sepsis with meningitis in a well-baby nursery.

Between March and May 2012, three neonates born at a regional maternity hospital developed Elizabethkingia meningoseptica (previously Chryseobacterium meningosepticum) sepsis with meningitis aged <10 days, and were treated successfully with intravenous ciprofloxacin plus vancomycin or piperacillin-tazobactam for three to six weeks. Four (16.6%) of 24 environmental specimens obtained from the nursery and delivery room were positive for this organism. All of the clinical isolates and two isolates from storage boxes for pacifiers and pacifier covers were genetically identical. After changing the storage boxes to stainless steel boxes that underwent regular autoclave sterilization, there were no further cases of infection with E. meningoseptica.

Refractive errors after the use of bevacizumab for the treatment of retinopathy of prematurity: 2-year outcomes.

PURPOSE: To evaluate the refractive outcomes in children treated after intravitreal injection of bevacizumab (IVB) for retinopathy of prematurity (ROP). METHODS: A retrospective, bi-centre study of 34 patients (64 eyes) was conducted. The patients were divided into three groups, patients received intravitreal IVB (IVB group), patients received combined IVB and laser treatment (IVB + Laser group), or patients received lens-sparing vitrectomy (IVB + LSV group). Cycloplegic refraction and axial length (AXL) were evaluated at 2 years old. RESULTS: The prevalences of myopia and high myopia were 47.5 and 10.0% in the IVB group, respectively, which were lower than those in the IVB + Laser (82.4 and 29.4%) and IVB + LSV (all 100%) groups (P = 0.001 and P < 0.001). The prevalences of emmetropia in the IVB group, IVB + Laser group, and IVB + LSV group were 50, 5.9, and 0% (P = 0.001). The AXL were similar among all groups. CONCLUSIONS: At the 2-year follow-up, severe ROP patients treated with IVB alone were more likely to remain emmetropic and had lower prevalences of myopia and high myopia. The development of high myopia in severe ROP patients could not be explained by AXL changes but may be associated with abnormalities in the anterior segment.

Prophylaxis of intravenous immunoglobulin and acyclovir in perinatal varicella.

UNLABELLED: Maternal chickenpox around the time of delivery can cause severe and even fatal illness in the newborn but an effectively preventive method has not yet been established. We proposed that a combination of intravenous immunoglobulin (IVIG) and acyclovir (ACV) intravenously could effectively prevent perinatal varicella. A group of 24 newborn infants whose mother had developed a varicella rash within 14 days before and after delivery were studied. Some 15 infants whose mothers' rash appeared within 7 days before and 5 days after delivery were categorised as an at-risk group and received IVIG prophylaxis (500 mg/kg) administered soon after birth or post-natal contact either alone or with intravenous acyclovir (5 mg/kg every 8 h) for a total of 5 days starting from 7 days after the onset of maternal rash. Of four infants receiving IVIG alone, two developed clinical varicella. None of ten infants receiving both IVIG and ACV contracted varicella. One infant receiving ACV alone had no varicella vesicles either. Of nine infants in the not at-risk group four had undetectable varicella-zoster virus antibody on admission and developed clinical varicella subsequently. CONCLUSION: The combination of intravenous immunoglobulin given soon after birth and prophylactic acyclovir intravenously administered 7 days after the onset of maternal rash can effectively prevent perinatal varicella.

Candidaemia in special care nurseries: comparison of albicans and parapsilosis infection.

OBJECTIVES: Candidaemia caused by Candida parapsilosis (CP) is being increasingly reported among infants in neonatal intensive care units (NICU). To assess relative severity, clinical manifestations of candidaemia caused by C. albicans (CA) and CP in a NICU were compared. METHODS: Between January 1994 and July 1997, episodes of candidaemia occurring among infants hospitalized in the NICU were identified in a children's hospital. The demographic characteristics, associated risk factors, clinical manifestations and outcome of the infants with CP fungaemia were collected and compared with those of the infants with CA fungaemia. RESULTS: Twenty-four episodes caused by CA and 22 episodes caused by CP were included in this study. No significant differences were found between the two groups for gestational age, birth weight, male gender, post-natal age at onset of candidaemia, frequency of antecedent neonatal events, prior duration of antibiotic therapy and hyperalimentation, as well as presence of central venous catheter (CVC). Infants with CA fungaemia were significantly more likely than those with CP fungaemia to present with hypoxaemia, bradycardia and respiratory distress requiring intubation, and have a longer prior duration of indwelling CVC and a higher dissemination rate. The eradication rate of candidaemia and overall case fatality rate were comparable in both groups. but CP fungaemia did not appear to cause acute lethal events. CONCLUSION: The presenting signs of CP fungaemia are relatively not so severe, but CP fungaemia, which is relatively difficult to eradicate, increases the morbidity and mortality of the infants.

Fluconazole therapy in neonatal candidemia.

We reviewed 62 episodes (from 59 infants) of neonatal candidemia that occurred between January 1994 and June 1999. Except 5 term babies, all infants were premature (median gestational age [GA], 30 weeks) and birth weight was less than 2,500 g (median, 1,300 g). Most infants had reported risk factors and other neonatal problems. The age at onset of candidemia ranged from 15 to 173 days with a median of 34 days. In addition to catheter removal, all but one infants received antifungal agents and candidemia was eradicated subsequently in 46 episodes (75%). Eighteen infants with 19 episodes ever received fluconazole therapy. Fluconazole was administered as the first line agent in 6 episodes and successfully cleared candidemia in 5 episodes. Fluconazole was used as an alternative agent in an additional 13 episodes after amphotericin B (am B) +/- flucytosine were given for a period without a satisfactory result and eradication of candidemia was achieved in 8 episodes subsequently. All 18 infants tolerated fluconazole well and no withdrawal was required on account of its adverse effect. In contrast, am B alone was administered as the first line agent in 55 episodes and successfully cleared candidemia in 32 episodes (58%). This retrospective analysis suggests that fluconazole appears to be safe in neonates and can be used as an alternative agent in treating neonatal candidemia. A large-scaled prospective study may be needed.

Association of fungal colonization and invasive disease in very low birth weight infants.

BACKGROUND: Fungi are common pathogens of nosocomial infections in the very low birth weight (VLBW) infants. The purpose of this study was to investigate the fungal colonization rate in VLBW infants and the association between fungal colonization and systemic fungal diseases. MATERIALS: Between January 1, 1996, and December 31, 1996, 116 infants with birth weight < 1500 g admitted to the neonatal intensive care unit of Chang Gung Children's Hospital in the first day of life were included in this prospective study. METHODS: Cultures from oropharynx, rectum, skin (groin and axilla), bag urine and endotracheal aspirates were obtained in the first 24 h after birth and weekly thereafter throughout their neonatal intensive care unit stay. Medical records were reviewed weekly. RESULTS: Fungal colonization was detected in 25 infants, among whom 17 infants developed colonization by 2 weeks of life. Candida albicans (61%) and Candida parapsilosis (29%) were the 2 most common organisms. The rectum (76%) was the most frequent site of colonization. Factors significantly associated with colonization were prolonged administration of antibiotic therapy, parenteral nutrition and intralipid emulsion. Three of 116 infants developed fungemia. The association between colonization and subsequent fungemia was demonstrated in 1 infant, representing 4% of colonized infants. CONCLUSION: Fungal colonization was detected in one-fifth of VLBW infants and represents a risk factor for fungemia. Because disease occurred in the absence of apparent colonization, factors other than colonization may contribute to invasive candidiasis.
