Clinical analysis of 8 cases of neonatal septicemia caused by Candida haemulonii in neonatal intensive care unit / 中华儿科杂志

<p><b>OBJECTIVE</b>To study the clinical characteristics, antibiotics sensitivity, outcome and risk factors of neonatal septicemia caused by Candida haemulonii.</p><p><b>METHOD</b>A retrospective analysis was performed on clinical characteristics and antibiotics sensitivity after 8 cases of neonatal septicemia caused by Candida haemulonii were identified; each of these patients had at least one positive result of bacterial culture for Candida haemulonii.</p><p><b>RESULT</b>The 8 cases born at gestational age of 178-260 d, weighing 835-2 055 g, developed the infection from May to July at 10-34 d after hospitalization. Among the 8 patients, 7 were cured, 1 died during hospitalization after the treatments were given up because of serious complications. The 8 patients with septicemia caused by Candida haemulonii had similar clinical chariacteristics to those of other neonatal candidemia, such as apnea, fever, abdominal distension, jaundice etc. They had abnormal auxiliary examination with increased C-reactive protein (CRP), declined platelet (PLT) count to different degrees. All of the 8 patients had peripherally inserted central catheter (PICC) and broad-spectrum antibiotics were applied. C. haemulonii as an emergent fungal pathogen had varying degrees of resistance to fluconazole, amphotericin B, itraconazole, or ketone, but was susceptible to voriconazole.</p><p><b>CONCLUSION</b>The characteristics of neonatal septicemia caused by Candida haemulonii were similar to those caused by other candida, and the main risk factors are the low birth weight, PICC, and usage of broad-spectrum antibiotics. It mainly occurred in May to July which is hot and humid season.</p>

Effects of gender on incidence of intraventricular hemorrhage in very low and extremely low birth weight infants / 中华围产医学杂志

Objective To examine the relationship between gender and intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI).Methods From January 1,1999 to December 31,2012,data on VLBWI and ELBWI,who were admitted to the neonatal intensive care unit of Yuying Children's Hospital within 14 d after birth,were retrospectively collected.The Chi-square test and t test were used to compare neonatal outcomes between male and female infants.The Logistic model was used to analyze the risk factors for IVH.Results A total of 1 008 cases were enrolled,including 615 males and 393 females,895 VLBWI and 113 ELBWI.The incidence of IVH was 15.1％ (152/1 008) and the incidence of severe IVH was 8.4％ (85/1 008).Compared with females,males had a higher total incidence of IVH [17.2％ (106/615) vs 11.7％ (46/393),x2=5.728,P＜0.05] and severe IVH [9.8％ (60/615) vs 6.4％ (25/393),x2=3.896,P＜0.05].These differences were also seen in VLBWI with a birth weight of 1 250 to 1 499 g [IVH:13.7％ (47/344) vs 7.8％ (17/217),x2=4.473,P=0.034; severe IVH:7.6％ (26/344) vs 2.8％ (6/217),x2=5.684,P=0.017].Logistic regression analysis showed that the risk factors for IVH were as follows:gestational age ＜28 weeks (aOR=2.012,95％CI:1.288-3.143,P＜0.05),neonatal respiratory distress syndrome (aOR=l.584,95％CI:1.007-2.492,P＜0.05),invasive mechanical ventilation (aOR=2.743,95％CI:1.826-4.121,P＜0.05),electrolyte disturbance (aOR=2.128,95％CI:1.092-4.149,P＜0.05) and periventricular leukomalacia (aOR=2.901,95％CI:1.312-6.416,P＜0.05),but not male sex (aOR=1.351,95％CI:0.917-1.991,P=0.128).The risk factors for severe IVH were gestational age ＜28 weeks (aOR=2.200,95％CI:1.305-3.708,P＜0.05),invasive mechanical ventilation (aOR=4.714,95％CI:2.809-7.911,P＜0.05) and electrolyte disturbance (aOR=2.232,95％CI:1.047 4.759,P＜0.05),but not male sex (aOR=1.361,95％CI:0.823 2.252,P=0.247).Conclusions Male VLBWI and ELBWI have a higher incidence of IVH and severe IVH,but male sex is not a risk factor for IVH or severe IVH.
