An Unusual Presentation of Pyloric Stenosis: A Case Report.

A full-term newborn female presented with non-bilious emesis immediately after feeding and abdominal distension on day one of life with neither palpable abdominal mass nor electrolyte derangements. The baby was initially admitted to rule out gastrointestinal obstruction versus sepsis as a cause of vomiting and abdominal distension. Initial imaging studies involving an upper gastrointestinal (GI) series showed obstruction at the level of the duodenum, but it was only during surgical exploration that the diagnosis of infantile hypertrophic pyloric stenosis was made. This case report highlights the atypical presentation of pyloric stenosis and the need to investigate cases of vomiting immediately after feeding in a newborn with ultrasonography at the least to minimize complications.

Mobile and online consumer tools to screen for autism do not promote equity.

LAY ABSTRACT: Many parents wonder if their child might have autism. Many parents use their smartphones to answer health questions. We asked, "How easy or hard is it for parents to use their smartphones to find 'tools' to test their child for signs of autism?" After doing pretend parent searches, we found that only one in 10 search results were tools to test children for autism. These tools were not designed for parents who have low income or other challenges such as low literacy skills, low English proficiency, or not being tech-savvy.

Pulmonary Vasoreactivity and Phenotypes in Pulmonary Arterial Hypertension Associated to Connective Tissue Diseases.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a fatal complication in patients with connective tissue disease (CTD). OBJECTIVE: The objective of the study was to study the prognostic value of the acute pulmonary vasoreactivity test with inhaled iloprost and its association with clinical deterioration in a tertiary care academic medical center. METHODS: We conducted a prospective study of patients with CTD and the diagnosis of PAH established by right heart catheterization. Patients were classified into classic responders, partial responders, and non-responders. The association of the pulmonary response and clinical deterioration was analyzed. RESULTS: We enrolled 25 patients (mean age of 47 ± 13.4 years); 88% were female. The most frequent rheumatologic diagnosis was systemic lupus erythematosus, in 16 (64%) patients. Seventy-two percent of patients were classified as non-responders, and 28% were partial responders. Patients with a partial response had lower right atrial pressure values (5.1 ± 3.1 vs. 8.5 ± 3.2, p = 0.01) and greater systolic pulmonary arterial pressure (87.6 ± 8.1 vs. 72.4 ± 16.2, p = 0.02), compared with non-responders. Non-responders had a tendency for a shorter time to clinical deterioration than partial responders (17.8 vs. 41.1 months, p = 0.052). CONCLUSIONS: Patients with a partial response to the acute pulmonary vasodilator test with inhaled iloprost had a longer clinical deterioration-free period than non-responders.

Human milk and clinical outcomes in VLBW infants: how compelling is the evidence of benefit?

Significant benefits to infant host defense, sensory-neural development, gastrointestinal maturation, and some aspects of nutritional status are observed when premature infants are fed their mothers' own milk. A reduction in infection-related morbidity in human milk-fed premature infants has been reported in nearly a dozen descriptive, and a few quasi-randomized, studies in the past 25 years. Studies on neurodevelopmental outcomes have reported significantly positive effects for human milk intake on mental and motor development, intelligence quotient, and visual acuity compared with the feeding of formula. Human milk-fed infants also have decreased rates of re-hospitalization after discharge. It is unclear how much human milk is needed to provide protection or at what postnatal age the protective effects maximize. More data are warranted to elucidate these questions. Despite the significant benefits of mothers' own milk, nutritional adequacy may be a limiting factor in the infant weighing less than 1500 g at birth. The overall nutritional needs of these infants can be supported with a nutrient supplement, or fortifier, added to the milk.
