Factors That Negatively Affect the Prognosis of Pediatric Community-Acquired Pneumonia in District Hospital in Tanzania.

Community-acquired pneumonia (CAP) is still the most important cause of death in countries with scarce resources. All children (33 months ± 35 DS) discharged from the Pediatric Unit of Itigi Hospital, Tanzania, with a diagnosis of CAP from August 2014 to April 2015 were enrolled. Clinical data were gathered. Dried blood spot (DBS) samples for quantitative real-time polymerase chain reaction (PCR) for bacterial detection were collected in all 100 children included. Twenty-four percent of patients were identified with severe CAP and 11% died. Surprisingly, 54% of patients were admitted with a wrong diagnosis, which increased complications, the need for antibiotics and chest X-rays, and the length of hospitalization. Comorbidity, found in 32% of children, significantly increased severity, complications, deaths, need for chest X-rays, and oxygen therapy. Malnourished children (29%) required more antibiotics. Microbiologically, Streptococcus pneumonia (S. p.), Haemophilus influenza type b (Hib) and Staphylococcus aureus (S. a.) were the bacteria more frequently isolated. Seventy-five percent of patients had mono-infection. Etiology was not correlated with severity, complications, deaths, oxygen demand, or duration of hospitalization. Our study highlights that difficult diagnoses and comorbidities negatively affect clinical evolution. S. p. and Hib still play a large role; thus, implementation of current vaccine strategies is needed. DBS is a simple and efficient diagnostic method for bacterial identification in countries with scarce resources.

Testing ethylglucuronide in maternal hair and nails for the assessment of fetal exposure to alcohol: comparison with meconium testing.

BACKGROUND: The deleterious effects exerted by prenatal ethanol exposure include physical, mental, behavioral, and/or learning disabilities that are included in the term fetal alcohol spectrum disorder. The measurement of ethylglucuronide (EtG) in alternative biological matrices, including neonatal and maternal hair, neonatal meconium, and maternal nails, is receiving increasing interest for the accurate evaluation of the in utero exposure to alcohol. OBJECTIVE: To evaluate the correlation between EtG in maternal hair and nails with EtG in neonatal meconium to further explore the suitability of these biomarkers in disclosing prenatal exposure to ethanol. METHODS: A total of 151 maternal hair strands (0-6 cm), nail clips (2-6 mm), and corresponding neonatal meconium and nails samples were obtained from neonatal wards of 4 Mediterranean public hospitals: Rome, Florence, and Belluno in Italy and Barcelona in Spain. Hair, nails, and meconium were analyzed for the presence of EtG by validated liquid chromatography mass spectrometry assay. Meconium was also analyzed for the presence of fatty acid ethyl esters (FAEEs) as a complementary biomarker of potential in utero exposure to alcohol. RESULTS: Eighteen newborns resulted in utero exposed to maternal alcohol consumption by FAEE testing in meconium with EtG values between 0.5 and 1.5 nmol/g. Unfortunately, none of these cases were confirmed by the presence of EtG in maternal hair and nails samples, which resulted all negative to this biomarker. DISCUSSION AND CONCLUSIONS: The results confirm that FAEEs and EtG in meconium are the best biomarkers to assess in utero exposure to maternal alcohol. EtG in hair and nails are not good biomarkers to disclose alcohol consumption lower than on daily basis and lower than 1-2 alcoholic units per day.
