Emergence Of Candida Parapsilosis As The Predominant Species Causing Candidemia In Children., I Levy, L G Rubin, Sanjeev Vasishtha, V Tucci, S K Sood

Sanjeev Vasishtha MD

An increase in the rate of isolation of Candida parapsilosis, relative to other Candida species, in our children's hospital led us to analyze the clinical and epidemiological variables associated with candidemia. We sought to determine if these variables are different for patients infected with C. parapsilosis. All episodes of candidemia occurring over a 7-year period were analyzed retrospectively. Of 81 episodes in 80 patients, 35 (43%) were in neonates, and 46 (57%) were in nonneonates. C. parapsilosis was isolated in 40 episodes (49%). C. parapsilosis was significantly more likely than non-C. parapsilosis species to be associated with prematurity (P = …

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: Cervical spine clearance in the very young child is challenging. Radiographic imaging to diagnose cervical spine injuries (CSI) even in the absence of clinical findings is common, raising concerns about radiation exposure and imaging-related complications. We examined whether simple clinical criteria can be used to safely rule out CSI in patients younger than 3 years. METHODS: The trauma registries from 22 level I or II trauma centers were reviewed for the 10-year period (January 1995 to January 2005). Blunt trauma patients younger than 3 years were identified. The measured outcome was CSI. Independent predictors of CSI were identified by …

Role Of Multiple Births In Very Low Birth Weight And Infant Mortality, B. Magee

B. Dale Magee

OBJECTIVE: To determine the percentage of very-low-birth-weight (VLBW) infants (g) and infant deaths attributable to multiple births in the general population and in women aged 35+. STUDY DESIGN: The year 2000 Massachusetts birth certificate database with linked births-deaths was examined. Etiologic fractions (EF) for VLBW and infant mortality attributable to multiples were calculated for the general population and the 35+ age group. The percentages of multiples occurring in the 35+ age group were calculated. Infant deaths due to congenital anomalies and "perinatal conditions" were calculated. RESULTS: There were 81,582 resident births in Massachusetts in 2000. Of them 4.3% were multiples. …

Role Of Smoking In Low Birth Weight, B. Magee, Dale Hattis, Nancy Kivel

B. Dale Magee

OBJECTIVE: To assess the role of smoking on low birth weight (LBW). STUDY DESIGN: From Massachusetts for 1998, 79,904 birth certificates were reviewed. Birth weight, gestational age, plurality and maternal race were analyzed in relation to the mother's smoking status during the pregnancy. The etiologic fraction (EF) was calculated for smoking and LBW for the group as a whole as well as for various subgroups. RESULTS: A total of 11.7% of women acknowledged smoking during pregnancy. The overall LBW rate was 6.83%. The relative risk (RR) of LBW among smokers was 1.58. For all births the EF for smoking was …

Mary M. Lee

OBJECTIVE: The incidence of congenital hypothyroidism (CH) detected by newborn screening in the US has increased significantly since the early 1990s. We defined the characteristics associated with the increased incidence. PATIENTS: A cohort of children with CH born during an earlier period of low incidence (1991-94) was compared with a cohort born during a later period when the incidence of CH had doubled (2001-04). MEASUREMENTS: Screening was performed with T4 as the primary marker and thyroid stimulating hormone (TSH) on selected specimens. Follow-up on hypothyroid children determined whether they had permanent or transient hypothyroidism. Cases were classified based on laboratory …

T Cell Receptor Vbeta Gene Usage In Thai Children With Dengue Virus Infection, Susan Gagnon, Anita Leporati, Sharone Green, Siripen Kalayanarooj, David Vaughn, Henry Stephens, Saroj Suntayakorn, Ichiro Kurane, Francis Ennis, Alan Rothman

Alan Rothman

T lymphocyte activation during dengue is thought to contribute to the pathogenesis of dengue hemorrhagic fever (DHF). We examined the T cell receptor Vbeta gene usage by a reverse transcriptase-polymerase chain reaction assay during infection and after recovery in 13 children with DHF and 13 children with dengue fever (DF). There was no deletion of specific Vbeta gene families. We detected significant expansions in usage of single Vbeta families in six subjects with DHF and three subjects with DF over the course of infection, but these did not show an association with clinical diagnosis, viral serotype, or HLA alleles. Differences …

Prediction Of Dengue Disease Severity Among Pediatric Thai Patients Using Early Clinical Laboratory Indicators, James A. Potts, Robert V. Gibbons, Alan L. Rothman, Anon Srikiatkhachorn, Stephen J. Thomas, Pra-On Supradish, Stephenie C. Lemon, Daniel H. Libraty, Sharone Green, Siripen Kalayanarooj

Sharone Green

BACKGROUND: Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS), in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health resources in endemic countries. METHODS AND FINDINGS: We compared clinical laboratory findings collected within 72 hours of fever onset from a prospective cohort children presenting to one of two hospitals (one urban and one rural) in Thailand. Classification and regression tree analysis was used to develop diagnostic algorithms using different …

Outcomes From Assisted Reproductive Technology, Bradley Van Voorhis

Bradley J Van Voorhis

The use of assisted reproductive technology (ART) for treating the infertile couple is increasing in the United States. The purpose of this paper is to review the short-term outcomes after ART. Pregnancy rates after ART have shown nearly continuous improvement in the years since its inception. A number of factors affect the pregnancy rate, with the most important being a woman's age. Certain clinical diagnoses are associated with a poorer outcome from ART, including the presence of hydrosalpinges, uterine leiomyomata that distort the endometrial cavity, and decreased ovarian reserve. Multiple gestations are the major complication after ART. New laboratory techniques, …

The Effect Of Magnesium Sulfate On Fetal Heart Rate Baseline Variability, A. Babaknia, Jennifer Niebyl

Jennifer R Niebyl

Variability of the baseline fetal heart rate is correlated with good fetal outcome, and loss of baseline variability has been observed as a sign of fetal distress. Central nervous system depressing drugs may also decrease fetal heart rate variability, and thus recognition of the effect of medication on the baseline fetal heart rate is important for accurate interpretation of fetal monitor tracings. In the cases reported, marked decrease in fetal heart rate variability was observed within 4 minutes of intravenous administration of magnesium sulfate, and fetal outcome was good in all cases.

Jennifer R Niebyl

The Advisory Committee on Immunization Practices recommends that all pregnant women be questioned concerning risk factors for hepatitis B virus infection and that those giving positive responses be serotested. The sensitivity, specificity, and predictive value of those recommended questions among 692 parturient women were determined. A total of 59 currently or previously infected women (hepatitis B surface antigen (HBsAg), antibody to hepatitis B surface antigen (anti-HBs), or antibody to hepatitis B core antigen (anti-HBc) seropositive) were compared with the 633 seronegative women. Among nonwhite women, the sensitivity of a positive response to any one of the recommended questions was 60%. …

Neonatal Outcome After Indomethacin Treatment For Preterm Labor, Jennifer Niebyl, F. Witter

Jennifer R Niebyl

Forty-six infants exposed to indomethacin in utero for treatment for preterm labor were compared with infants from two control groups. In one control group the next consecutive patient treated with a tocolytic agent was used, and the other control group was formed by picking the next consecutive patient matched by gestational age who did not receive any tocolytic agent. There was no significant difference in Apgar scores, birth weight, or gestational age in the three groups. The incidence of neonatal complications including hypocalcemia, hypoglycemia, respiratory distress syndrome, patient ductus arteriosus, sepsis, and neonatal mortality were not significantly different in the …

A Placebo-Controlled Randomized Trial Of The Terbutaline Pump For Prevention Of Preterm Delivery, K. Wenstrom, C. Weiner, D. Merrill, Jennifer Niebyl

Jennifer R Niebyl

To determine the efficacy of the terbutaline pump for the prevention of preterm delivery, patients in preterm labor defined by progressive cervical change underwent intravenous magnesium sulfate tocolysis (with or without oral indomethacin, as necessary), and once labor was arrested, were randomized to one of three treatment arms: terbutaline by pump, saline by pump (blinded), or oral terbutaline. If recurrent preterm labor occurred despite maximization of therapy, the treatment arm was determined and therapy was changed; saline pump and oral terbutaline were switched to terbutaline pump, terbutaline pump was switched to oral terbutaline. Patients who continued to labor were readmitted …

Penile Nerve Block For Newborn Circumcision, L. Maxwell, M. Yaster, R. Wetzel, Jennifer Niebyl

Jennifer R Niebyl

Circumcision in neonates is performed, almost universally, without anesthesia or analgesia. It is associated with pain, crying, agitation, and physiologic stress. Twenty infants receiving penile nerve block for circumcision were compared with ten infants having circumcision without anesthesia. Heart rate and blood pressure rose 34 and 15%, respectively, in unblocked infants, and were unchanged in infants receiving local anesthesia. Oxygen saturation declined 16% in unanesthetized infants compared with 6% in blocked infants (P less than .03). Anesthetized infants were less agitated and cried less. Peak plasma concentrations of the local anesthetic lidocaine averaged 0.51 +/- 0.17 microgram/mL (range 0.1-1.6), well …
