Both protein and energy malnutrition are common in neonates and infants with congenital heart disease (CHD). Neonates with CHD are at increased risk of developing necrotizing enterocolitis (NEC), particularly the preterm population. Mortality in patients with CHD and NEC is higher than for either disease process alone. Standardized feeding protocols may affect both incidence of NEC and growth failure in infants with CHD. The roles of human milk and probiotics have not yet been explored in this patient population.

OBJECTIVE: To evaluate three guidelines for selecting short children for diagnostic workup in a general pediatric clinic.
METHODS: All patients (n = 131) aged 3.00-9.99 years who were referred for growth failure to a general pediatric clinic were evaluated for their medical history and growth and examined. All of them underwent the same standardized diagnostic workup. Retrospectively, the criteria for the diagnostic workup from three guidelines (proposed in the Netherlands, Finland and the UK) were applied, and their sensitivity was assessed. A Dutch reference sample (n = 958) was used for calculating population specificity.
RESULTS: In 23 patients (17.6%), a pathological cause of their growth failure was found. The sensitivity of the original Dutch, Finnish and British guidelines was 73.9, 78.3 and 56.5% and their specificity 98.5, 83.7 and 95.8%, respectively. When adding recent growth deflection to the Dutch guideline, sensitivity increased to 87%, but specificity decreased markedly (to 87%).
CONCLUSIONS: The proposed cutoff values for height standard deviation score and distance to target height/mid-parental height, as used in the Netherlands and Finland, are effective for population growth monitoring, and superior to the monitoring algorithm in the UK. Growth deflection irrespective of height is an important sign of acquired growth disorders, but its specificity is too low for population screening.

BACKGROUND: Shigella is a leading cause of childhood diarrhea mortality in sub-Saharan Africa. Current World Health Organization guidelines recommend antibiotics for children in non cholera-endemic areas only in the presence of dysentery, a proxy for suspected Shigella infection.
METHODS: To assess the sensitivity and specificity of the syndromic diagnosis of Shigella-associated diarrhea, we enrolled children aged 6 months to 5 years presenting to 1 of 3 Western Kenya hospitals between November 2011 and July 2014 with acute diarrhea. Stool samples were tested using standard methods for bacterial culture and multiplex polymerase chain reaction for pathogenic Escherichia coli. Stepwise multivariable logit models identified factors to increase the sensitivity of syndromic diagnosis.
RESULTS: Among 1360 enrolled children, median age was 21 months (interquartile range, 11-37), 3.4% were infected with human immunodeficiency virus, and 16.5% were stunted (height-for-age z-score less than -2). Shigella was identified in 63 children (4.6%), with the most common species being Shigella sonnei (53.8%) and Shigella flexneri (40.4%). Dysentery correctly classified 7 of 63 Shigella cases (sensitivity, 11.1%). Seventy-eight of 1297 children without Shigella had dysentery (specificity, 94.0%). The combination of fecal mucous, age over 23 months, and absence of excessive vomiting identified more children with Shigella-infection (sensitivity, 39.7%) but also indicated antibiotics in more children without microbiologically confirmed Shigella (specificity, 82.7%).
CONCLUSIONS: Reliance on dysentery as a proxy for Shigella results in the majority of Shigella-infected children not being identified for antibiotics. Field-ready rapid diagnostics or updated evidence-based algorithms are urgently needed to identify children with diarrhea most likely to benefit from antibiotic therapy.

Cardio-facio-cutaneous syndrome (CFC) is one of the RASopathies that bears many clinical features in common with the other syndromes in this group, most notably Noonan syndrome and Costello syndrome. CFC is genetically heterogeneous and caused by gene mutations in the Ras/mitogen-activated protein kinase pathway. The major features of CFC include characteristic craniofacial dysmorphology, congenital heart disease, dermatologic abnormalities, growth retardation, and intellectual disability. It is essential that this condition be differentiated from other RASopathies, as a correct diagnosis is important for appropriate medical management and determining recurrence risk. Children and adults with CFC require multidisciplinary care from specialists, and the need for comprehensive management has been apparent to families and health care professionals caring for affected individuals. To address this need, CFC International, a nonprofit family support organization that provides a forum for information, support, and facilitation of research in basic medical and social issues affecting individuals with CFC, organized a consensus conference. Experts in multiple medical specialties provided clinical management guidelines for pediatricians and other care providers. These guidelines will assist in an accurate diagnosis of individuals with CFC, provide best practice recommendations, and facilitate long-term medical care.

Jennifer, age 2 years, is being seen for her regular 2-year well child visit. You note her weight is only at the 5% and has been dropping percentiles over the past year When you ask her mother about Jennifer\'s diet, she reports Jennifer is a \"picky eater\" and often complains of a \"stomach ache.\" Her mother reports her stomach looks \"bloated. \" Steven, age 7 years, is brought into the clinic because of recurrent abdominal pain with occasional constipation or diarrhea. Steven\'s mother had been told in the past that he probably had \"irritable bowel syndrome\" but changes in his diet, occasional use of a laxative, and relaxation techniques have not improved his symptoms. Rebecca, age 12 years, is brought into your clinic because her mother has recently learned that two first cousins have been diagnosed with celiac disease. She is wondering if Rebecca should be screened for this condition since she has heard it runs in families.
