The nucleotide sequences of the mitochondrial genomes from patients with Leber hereditary optic neuropathy (LHON) were used for phylogenetic analysis to study the origin and population history of pathogenic mitochondrial mutations. Sequences of both the coding region (8300 bp) and the more rapidly evolving noncoding control region (1300 bp) were analyzed.(More)
The segregation of a heteroplasmic silent polymorphism in the mitochondrial ND6 gene has been followed in a human maternal lineage comprising eight individuals and spanning three generations. Heteroplasmy persisted in all eight maternally related family members. More importantly, the frequencies of the two alleles showed relatively little variation among(More)
BACKGROUND Little information in the literature exists to guide consult interactions between different medical specialties.

Thoracic endometriosis syndrome is a well-described, rare manifestation of endometriosis. We present a case of a 35-year old woman undergoing controlled ovarian stimulation prior to in vitro fertilization (IVF) who developed bilateral hemorrhagic pleural effusions. She was initially diagnosed with ovarian hyperstimulation syndrome, a complication of(More)
Glucagonomas are slow-growing, rare pancreatic neuroendocrine tumors. They may present with paraneoplastic phenomena known together as the “glucagonoma syndrome.” A hallmark sign of this syndrome is a rash known as necrolytic migratory erythema (NME). In this paper, the authors describe a patient with NME and other features of the glucagonoma syndrome. The(More)
PROBLEM The U.S. health care system is undergoing a major transformation. Clinical delivery systems are now being paid according to the value of the care they provide, in accordance with the Triple Aim, which incorporates improving the quality and cost of care and the patient experience. Increasingly, financial risk is being transferred from insurers to(More)
