BackgroundIn 2011, a large outbreak of hand, foot and mouth disease (HFMD) in Vietnam resulted in 113,121 children seeking medical attention, of whom170 died. Understanding the epidemiology of fatal HFMD may improve treatment and help targeting prevention activities for vulnerable populations. We describe epidemiological and clinical characteristics of children who died from HFMD in Vietnam in 2011.MethodsClinical data were obtained through reviewing medical records of the deaths occurring from January through December 2011 in all hospitals in Vietnam. Hospitals reported any deaths among patients with laboratory-confirmed enterovirus (EV) infection to the Ministry of Health. Data were extracted from the national database.ResultsOf the 169 deaths reviewed for whom records were available, 87% were 3-year-old or younger, 69% were male, 18% attended daycare, 89% lived in Southern Vietnam, and 85% of the deaths occurred between May-October 2011. One hundred thirty (77%) cases sought treatment in a hospital within three days of onset of illness. Symptoms at admission included fever (98%), myoclonus (66%), vomiting (53%), oral ulcers (50%) and vesicular erythema (50%). One hundred six (75%) cases had leukocytosis and 91 (54%) had hyperglycemia. One hundred three (61%) tested positive for EV, of which 84 (82%) were positive for EV71.ConclusionsDeaths associated with HFMD occurred throughout 2011 among males three years or younger who were cared for at home. The HFMD control program should focus on interventions at the household level. Clinicians should be alerted to symptoms suggestive of severe HFMD including fever, myoclonus, vomiting, oral ulcers and vesicles with high white blood cell count especially in young children.
Objective To report outcomes associated with the administration of granulocyte colony–stimulating factor (G-CSF) to women with chronic neutropenia during pregnancy. Methods We conducted an observational study of women of child-bearing potential with congenital, cyclic, idiopathic, or autoimmune neutropenia enrolled in the Severe Chronic Neutropenia International Registry to determine outcomes of pregnancies, without and with chronic G-CSF therapy, 1999–2014. Treatment decisions were made by the patients’ personal physicians. A research nurse conducted telephone interviews of all enrolled U.S. women of child-bearing potential using a standard questionnaire. Comparisons utilized Fisher’s exact test analysis and Student’s t-test. Results One-hundred seven women reported 224 pregnancies, 124 without G-CSF therapy and 100 on chronic G-CSF therapy (median dose: 1.0 mcg/kg/day, range 0.02–8.6 mcg/kg/day). There were no significant differences in adverse events between the groups considering all pregnancies or individual mothers, e.g., spontaneous terminations (all pregnancies: no G-CSF 27/124, G-CSF 13/100; P=0.11, Fisher’s exact test,), preterm labors (all pregnancies, no G-CSF 9/124, G-CSF 2/100, P=0.12,). A study with at least 300 per group would be needed to detect a difference in these events with 80% statistical power (alpha=0.05). Four newborns of mothers with idiopathic or autoimmune neutropenia not on G-CSF (4/101) had life-threatening infections, whereas there were no similar events (0/90) in the treated group, but this difference was also not statistically significant. (p=0.124). Adverse events in the neonates were similar for the two groups. Conclusions This observational study showed no significant adverse effects of administration of G-CSF to women with severe chronic neutropenia during pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
