Developing a portable field unit to improve well-child care.

Background: Pediatric growth tracking has been identified as a top priority by international health agencies to assess the severity of malnutrition and stunting. However, remote low-resource settings often lack the necessary infrastructure for longitudinal analysis of growth for the purposes of early identification and immediate intervention of stunting.

Methods: To address this gap, we developed a portable field unit (PFU) capable of identifying a child over the course of multiple visits, each time adding new anthropomorphic measurements.

Co-existence of X-linked hypophosphatemic rickets (XLH) and primary hyperparathyroidism: case report and review of the literature.

X-linked hypophosphatemic rickets (XLH) is a dominant disorder characterized by hypophosphatemia due to impaired renal tubular reabsorption of inorganic phosphate. Cardinal manifestations include defective calcification of cartilage and bone, growth retardation and resistance to phosphorus and vitamin D therapy. Although secondary hyperparathyroidism (HPT) is a common complication of treatment, autonomous HPT is rare, especially in the absence of previous phosphate therapy.
