TL;DR: The distribution of immune biomarkers in cord blood across gestational age is described and the association between biomarker level patterns and preterm birth is investigated to provide important information that could be used to guide additional studies aimed at determining mechanisms that contribute to pre term birth.
Abstract: OBJECTIVES. Inflammation has been associated with preterm delivery and adverse neonatal outcomes such as cerebral palsy and chronic lung disease. However, no study to date has simultaneously examined a wide range of inflammatory mediators and their relationship to gestational age. We sought to describe the distribution of immune biomarkers in cord blood across gestational age and to investigate the association between biomarker level patterns and preterm birth. PATIENTS AND METHODS. As part of a large-scale molecular epidemiological study of preterm birth conducted at Boston Medical Center, this study analyzed both clinical and biomarker data from 927 births. Twenty-seven biomarkers were simultaneously quantified by immunoassay. The associations between the quartiles of 27 biomarkers and 3 gestational groups (≤32, 33–36, and ≥37 weeks) were analyzed. Biomarkers found to be significant were further analyzed for dose-response correlation with preterm birth by logistic regression, adjusted for pertinent demographic and clinical factors. RESULTS. The 27 biomarkers could be classified into 1 of 3 groups: (1) biomarkers increased in preterm birth (interleukin [IL]-2, IL-4, IL-5, IL-8, IL-10, monocyte chemoattractant protein 1, macrophage inflammatory protein [MIP]-1α, MIP-1β, soluble IL-6 receptor α, tumor necrosis factor α, soluble tumor necrosis factor receptor I, and TREM-1 [triggering receptor expressed on myeloid cells 1]); (2) biomarkers decreased in preterm birth (brain-derived neurotrophic factor, IL-1β, IL-18, matrix metalloproteinase 9, and neurotrophin 3); and (3) biomarkers not associated with preterm birth (IL-6, IL-12, IL-17, granulocyte/macrophage colony-stimulating factor, interferon γ, macrophage migration inhibitory factor, neurotrophin 4, RANTES [regulated on activation, normal T-cell expressed and secreted], transforming growth factor β, and tumor necrosis factor β). CONCLUSIONS. Biomarkers have different directions of association with prematurity; for significant biomarkers, the strength of association increases with biomarker concentration. Our results provide important information that could be used to guide additional studies aimed at determining mechanisms that contribute to preterm birth.

TL;DR: It is concluded that precocious puberty in children with NF-1 is found exclusively in those who have OPTs involving the optic chiasm, and biochemical evidence of hypothalamic-pituitary-gonadal axis activation may be demonstrated, even without provocative testing.

TL;DR: The National Wilms Tumor Study constitutes a unique resource for study of clinical, pathologic, and epidemiologic features of Wilms tumor (WT).
Abstract: Background
The National Wilms Tumor Study (NWTS) constitutes a unique resource for study of clinical, pathologic, and epidemiologic features of Wilms tumor (WT).
Procedure
Data from NWTS-3,4,5 were compiled for 7,455 patients with tumors of favorable (FH) or anaplastic (AH) histology. The associations of birth weight (BW) and age-at-onset with gender, intralobar (ILNR), and perilobar (PLNR) nephrogenic rests, tumor focality, congenital malformation syndromes, and tumor histology were analyzed using descriptive statistics and linear regression.
Results
Mean BWs for male and female patients without PLNR were 3.52 and 3.36 kg, respectively, and for those with PLNR were 0.12 kg and 0.15 kg heavier. Mean age was 45 months for males with no rests whose tumors were unifocal and of triphasic favorable histology. ILNR or multifocality decreased the mean age by 18 and 10 months, respectively, whereas female gender, blastemal/FH or AH increased it by 3, 10, and 16 months. Over 90% of multifocal tumors occurred in the presence of demonstrated ILNR or PLNR or both. The apparent bimodality of the age distributions and later mean ages-at-onset for females with both unifocal and multifocal tumors were explained in part by the relative deficit in females of ILNR versus PLNR-associated tumors.
Conclusions
These observations support the view that there are multiple pathways to Wilms tumorigenesis. They will facilitate selection of informative subgroups of patients for molecular analysis that may serve to identify the putative pathway for the majority of patients who cannot be classified provisionally on the basis of ILNR or PLNR.

TL;DR: It is concluded that African-American mothers' perception of their residential environment and frequency of stressful life events are associated with very low birthweight in their infants.
Abstract: We performed a hospital-based case-control study of African-American mothers to explore the relation between a mother's perception of her own residential environment and very low birthweight. We administered a structured questionnaire to mothers of very-low-birthweight ( 2,500 gm; N = 52) infants. The groups had similar sociodemographic characteristics. The vast majority of participants were unmarried and had no private medical insurance. The odds ratios of very low birthweight fluctuated between 1.7 and 3.2 for African-American mothers who rated their neighborhoods (in terms of police protection, protection of property, personal safety, friendliness, delivery of municipal services, cleanliness, quietness, and schools) unfavorably. Additionally, the odds ratio of very low birthweight for mothers exposed to three or more stressful life events during pregnancy was 3.1 (95% confidence interval = 1.2-8.2). We conclude that African-American mothers' perception of their residential environment and frequency of stressful life events are associated with very low birthweight in their infants.

TL;DR: It is concluded that propranolol is effective in infantile hemangiomas, including post‐proliferative phase, and should be considered as the first‐line therapy in that setting.
Abstract: Pharmacological therapies for infantile hemangiomas were considered effective only during the proliferative phases. Recently reported beneficial effects of propranolol may extend beyond the proliferative phase of infantile hemangiomas. The purpose of the study was to assess the effect of oral propranolol therapy for infantile hemangiomas beyond the proliferative phase of these lesions. Members of the Society for Pediatric Dermatology were invited to participate in a multicenter retrospective study. Only children with infantile hemangiomas with documented cessation of lesions' growth or those older than 12 months of age were eligible for the study. Clinical and demographic information and digital photographs before, at the start, and following the treatment were collected. Scaled panels of photographs were distributed among preselected experienced pediatric dermatologists. Visual analog scale was used to assess photographs for each case. Paired t-test was used for statistical analyses. Data on 49 eligible patients from eight pediatric dermatology centers was collected. Seven cases were excluded because of insufficient photographic documentation. The age of the patients at the start of propranolol therapy ranged 7 to 120 months (mean 28 mos, median 22 mos). The duration of propranolol therapy ranged 1 to 8 months (mean 3.6 mos). The mean visual analog scale score before the treatment was 6.8 ± 2.15, and mean reduction in the visual analog scale score at the assessment was 2.6 ± 1.74 (p < 0.001). The rate of visual analog scale reduction was 0.4 per month before the start of the therapy, while this rate was accelerated to 0.9 per months following the therapy (p < 0.001). No significant side effects were reported. We conclude that propranolol is effective in infantile hemangiomas, including post-proliferative phase, and should be considered as the first-line therapy in that setting.
