RESUMO
Introduction: Most recent clinical reports from the American Academy of Pediatrics (AAP) concluded current evidence does not support routine universal administration of probiotics to preterm infants, particularly those with birth weight <1000 grams. Despite this, the use of probiotics is increasing in US neonatal intensive care units (NICU).Objectives: Collaborating with the Perinatal Neonatal Medicine of AAP, we conducted a national survey to obtain neonatologist opinion on probiotics use.Methods: Survey questionnaires were sent to 3000 neonatologists via email.Results: Of 3000 potential respondents, 249 (8.3 %) completed the survey. Seventy-five (30%) neonatologists working in 23 different NICUs reported using probiotics in their practice, while 168 (70%) neonatologists working in 54 different NICUs reported not using probiotics. Of those not currently use probiotics, 49% indicated they would consider using probiotics in the future vs. 12% indicating they would not use probiotics. The most common indication for probiotics use was average gestational age < 32 weeks and mean birth weight < 1500 grams. Probiotics were discontinued at mean gestational age of 35 weeks. Respondents who prescribe probiotics were more likely to work in a setting without fellowship or residency training (48% vs 20%). Probiotics users were more often from the West (29 % vs 7%) and less often from Northeast (5% vs 34%) compared to non-users. The proportion of those using probiotics did not significantly differ by NICU size, NICU level, or years working in a NICU. Similac Tri-Blend, Evivo, and Culturelle were the top three probiotics used in the respondent's NICU.Conclusion: Though a majority of respondents are not currently using probiotics in their NICU, a large number of nonusers are interested in using probiotics in the future. Differences continue to exist in the brand of probiotics used in US NICUs.

Introduction Crohn's disease (CD) is an immune-mediated inflammatory bowel disease (IBD) that can affect any portion of the gastrointestinal tract from the mouth to the anus. The clinical course of CD is characterized by periods of symptomatic relapse and remission. Clinical variables may identify a subset of patients with CD at risk for relapse. Identifying these patients, and early stratification-based treatment would be of utmost clinical importance in optimizing the management and is likely to improve long-term disease outcome. In pediatric-onset IBD there is a paucity of data for predicting clinical behavior and results are conflicting. With this background, we hypothesized that routinely measured clinical variables at the time of diagnosis would predict relapse in patients with CD, and sought to investigate the clinical predictors of relapse present at the time of diagnosis in our patient population. We further compared differences in clinical variables and laboratory values for patients who relapsed early, compared with those who relapsed late. Methods We conducted a retrospective chart review of patients diagnosed with CD by clinical, radiological, endoscopic and histological criteria at St. John Providence Children's Hospital pediatric GI clinic between 01/2006 and 12/2014. Patients were followed until they had their first relapse or for three years from diagnosis, whichever was earlier. Variables studied included demographic factors (age, gender, race, BMI, BMI percentiles and family history of IBD), presenting symptoms (blood in stools, nocturnal stools, fever, and extra-intestinal manifestations), phenotypic characteristics (using Montreal classification), and laboratory data [white blood cell (WBC) count, hemoglobin, hematocrit, platelet count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)]. Results Twenty-nine patients were included in the study. One was lost to follow up, and 28 were included in the analyses. The relapse rate was 50% at three years, and 32% patients relapsed within one year of diagnosis. Low BMI percentile at diagnosis (41.5 ± 28.8 vs. 18.0 ± 20.3; p-value 0.03) was a predictor of relapse. Comparing early relapse to those who relapsed late, there were no statistically significant differences between the two groups. Conclusions Low BMI percentile at presentation was associated with increased risk of relapse, suggesting that routinely measured clinical variables may have role in predicting first relapse in this patient population. There was no significant difference in the variable comparing patients who relapsed early vs. those who relapsed late. Future prospective studies with larger sample sizes need to be done to predict relapse.
RESUMO
OBJECTIVE: To document the immunization rates, factors associated with incomplete immunization, and missed opportunities for immunizations in children affected by HIV presenting for routine outpatient follow-up. METHODS: A cross-sectional study of immunization status of children affected by HIV presenting for routine outpatient care was conducted. RESULTS: Two hundred and six HIV affected children were enrolled. The median age of children in this cohort was 6 y. One hundred ninety seven of 206 children were HIV infected, nine were HIV exposed, but indeterminate. Fifty (25 %) children had incomplete immunizations per the Universal Immunization Program (UIP) of India. Hundred percent of children had received OPV. Ninety three percent of children got their UIP vaccines from a government clinic. Children with incomplete immunization were older, median age of 8 compared to 5 (p = 0.003). Each year of maternal education increased the odds of having a child with complete UIP immunizations by 1.18 (p = 0.008)-children of mothers with 6 y of education compared to those with no education were seven times more likely to have complete UIP vaccine status. The average number of visits to the clinic by an individual child in a year was 4. This represents 200 missed opportunities for immunizations. CONCLUSIONS: HIV infected children are at risk for incomplete immunization coverage though they regularly access medical care. Including routine immunizations, particularly catch-up immunizations in programs for HIV infected children maybe an effective way of protecting these children from vaccine preventable disease.

Though various advantages associated with the use of letrozole as an ovulation inducing drug are documented, there is inadequate information regarding its effect on endometrial receptivity. Expression of endometrial receptivity markers including αvß3 integrin, L-selectin, LIF, and pinopods during the implantation window in infertile women stimulated with letrozole or clomiphene citrate (CC), and spontaneous cycles is investigated. A total of 36 women were included in the study out of which 16 women were diagnosed with primary unexplained infertility and the other 20 women with severe oligoasthenozoospermic/azoospermic male partners. Both groups were sub-divided into three groups; women stimulated with letrozole, or with CC, and the third group was allowed to ovulate spontaneously (natural cycles). Women having natural cycles and not given any drug were considered as controls. Once ovulation was confirmed by ultrasonography, endometrial samples were collected on the seventh day post-ovulation and analyzed. In women with unexplained infertility treated with letrozole and CC, epithelial and stromal expression of αvß3 integrin, L-selectin, leukemia inhibitory factor (LIF), and pinopod formation was found to be significantly higher as compared to controls. Expression of these receptivity markers was found to be comparable amongst the letrozole, CC, and control groups in women with severe oligoasthenozoospermic/azoospermic male partners. Cell cycle analysis showed similar cell cycle phase fractions on comparing the CC and the letrozole groups. Stimulation with letrozole and CC appears to enhance endometrial receptivity in women with unexplained infertility. However, letrozole and CC did not have any significant effect on the endometrial receptivity markers of women with severe oligoasthenozoospermic/azoospermic male partners.

OBJECTIVE: To investigate bacterial associations of S. pneumoniae, S. aureus, and H. influenzae in the nasopharynx of ambulatory children with HIV infection. METHODS: A cross-sectional nasopharyngeal swab survey of 148 children with HIV infection from West Bengal presenting for routine outpatient care was conducted. RESULTS: Forty-one (28 %) children carried S. pneumoniae, 35 (24 %) carried S. aureus and 39 (26 %) carried H. influenzae. Seventeen (11 %) had dual colonization with S. pneumoniae and H. influenzae, 13(8.8 %) had dual colonization with S. pneumoniae and S. aureus, and 6(4 %) had dual colonization with S. aureus and H. influenzae. Three (2 %) had triple carriage with H. influenzae, S. aureus, and S. pneumoniae. Neither Cotrimoxazole prophylaxis nor ART (antiretroviral therapy) affected colonization with any organism. There was no association between HIV immune status, recent antibiotic use, exposure to other children, household tuberculosis exposure and colonization with any organism. There was a strong negative association between malnutrition and colonization with H. influenzae. CONCLUSIONS: The negative association between S. pneumoniae and S. aureus colonization in the nasopharynx described in healthy populations was not present. The authors found a strong positive association between carriage with H. influenzae and S. pneumoniae. These findings provide insight into the increased risk of invasive disease from these organisms in HIV infected children.

OBJECTIVE: To determine nasopharyngeal colonization rates of two vaccine preventable bacterial pathogens Hemophilus influenzae type b (Hib), and Streptococcus pneumoniae (Pneumococcus), antibiotic susceptibility of isolates, factors associated with their colonization, and immunization history in a cohort of HIV infected children. METHODS: The authors conducted a cross-sectional nasopharyngeal swab survey of 151 children affected with HIV presenting for routine outpatient care in West Bengal, India. RESULTS: 151 HIV affected children were enrolled. The median age was 6, 148/151 children were HIV positive, 65% had moderate to severe malnutrition, 53% were moderately to severely immunosuppressed, 17% were on antiretroviral therapy (ART), 90% were on cotrimoxazole prophylaxis (TMP/SMX). None had received the pneumococcal or Hib conjugate vaccines. Hib prevalence was 13% and pneumococcal prevalence was 28%. Children with normal or moderate immune suppression had high rates of colonization compared to those with severe immunosuppression (71% Hib, 61% pneumococcus). Hib and pneumococcal isolates had high rates of resistance to tested antibiotics including TMP/SMX and third generation cephalosporins. Neither ART nor TMP/SMX prevented colonization. Children colonized with multidrug resistant isolates had high rates of exposure to TMP/SMX. CONCLUSIONS: HIV infection, late access to ART, high rates of colonization to resistant organisms and lack of access to vaccines makes this population vulnerable to invasive disease from Hib and pneumococcus.

A 2-month-old infant presented to our emergency department with fever, altered consciousness, and focal seizures of acute onset. He had vesicular skin lesions over the right preauricular region. CT brain showed a large hypodense lesion involving the left temporo-parietal region, left basal ganglia and left thalamus. MRI brain revealed bilateral multifocal corticomedullary lesions suggestive of encephalitis. CSF-PCR was positive for herpes simplex virus (HSV) type I. He was treated with standard dose intravenous acyclovir for 15 days along with a trial of pulse methylprednisolone, but was readmitted within a week with features of an early relapse. The infant survived but developed significant neurological sequelae. Although treatment of HSV is available, the neurological outcome is guarded even with adequate antiviral therapy. Adjunct corticosteroid therapy did not appear to attenuate the neurological sequelae.
