Thinking outside "The Box": Case-based didactics for medical education and the instructional legacy of Dr John M. Graham, Jr.

The increasing demand for advanced genomic services has finally come to the attention of healthcare systems and stakeholders who are now eager to find creative solutions to increase the pool of genomic literate providers. Training in genetics and dysmorphology has historically been conducted as a self-driven practice in pattern recognition, ideally within a formal or informal apprenticeship supervised by a master diagnostician. In recent times, case-based learning, framed by flipped classroom pedagogy have become the preferred teaching methods for complex medical topics such as genetics and genomics.

HIST1H1E heterozygous protein-truncating variants cause a recognizable syndrome with intellectual disability and distinctive facial gestalt: A study to clarify the HIST1H1E syndrome phenotype in 30 individuals.

Histone Gene Cluster 1 Member E, HIST1H1E, encodes Histone H1.4, is one of a family of epigenetic regulator genes, acts as a linker histone protein, and is responsible for higher order chromatin structure. HIST1H1E syndrome (also known as Rahman syndrome, OMIM #617537) is a recently described intellectual disability (ID) syndrome.

Hospital-based acute care after outpatient colonoscopy: implications for quality measurement in the ambulatory setting.

Introduction: Ambulatory surgery centers now report immediate hospital transfer rates as a measure of quality. For patients undergoing colonoscopy, this measure may fail to capture adverse events, which occur after discharge yet still require a hospital-based acute care encounter.

Objective: We conducted this study to estimate rates of immediate hospital transfer and hospital-based acute care following outpatient colonoscopy performed in ambulatory surgery centers.

Advances in Hirschsprung disease genetics and treatment strategies: an update for the primary care pediatrician.

Hirschsprung disease (HSCR) is a multigenic condition with variable presentation. Most commonly, it presents in the neonatal period as a functional intestinal obstruction secondary to failure of caudal migration of the enteric nervous system. Classically, this manifests as dilated proximal bowel and constricted distal bowel with absent ganglia and hypertrophic nerve trunks.

Distinctive phenotype in 9 patients with deletion of chromosome 1q24-q25.

Reports of individuals with deletions of 1q24→q25 share common features of prenatal onset growth deficiency, microcephaly, small hands and feet, dysmorphic face and severe cognitive deficits. We report nine individuals with 1q24q25 deletions, who show distinctive features of a clinically recognizable 1q24q25 microdeletion syndrome: prenatal-onset microcephaly and proportionate growth deficiency, severe cognitive disability, small hands and feet with distinctive brachydactyly, single transverse palmar flexion creases, fifth finger clinodactyly and distinctive facial features: upper eyelid fullness, small ears, short nose with bulbous nasal tip, tented upper lip, and micrognathia. Radiographs demonstrate disharmonic osseous maturation with markedly delayed bone age.
