We report three cases of benign mediastinal lymphadenopathy revealed by chest radiography in patients ranging in age from 61 to 75 years. All three patients had severe coronary heart disease and a history of several episodes of acute cardiac decompensation. Chest CT scanning contributed to the diagnosis by revealing the existence of multiple enlarged lymph nodes, mostly 10 to 17 mm in short-axi...

Drosophila tinman is an NK-class homeobox gene required for formation of the dorsal vessel, the insect equivalent of the vertebrate heart. Vertebrate sequences related to tinman, such as mouse Nkx-2.5, chicken cNkx-2.5, Xenopus XNkx-2.5 and XNkx-2.3 are expressed in cardiac precursors and in tissues involved in induction of cardiac mesoderm. Mice which lack a functional Nkx-2.5 gene die due to ...

BACKGROUND Adverse aortic remodeling, such as dilation, is associated with multiple cardiovascular disease (CVD) risk factors. We sought to determine whether measures of enlarged aortic diameters improve prediction of incident adverse CVD events above standard CVD risk factors in a community-dwelling cohort. METHODS AND RESULTS Participants from the Framingham Offspring and Third Generation C...

The pathogenesis of Hashimoto’s encephalopathy has not been clearly elucidated and involvement of autoimmune damage has been proposed. We report a 23-year-old man who was emergently hospitalized for paroxysmal syncope and involuntary tremor with normal physical examination except for low heart rate. The patient was characterized by neurological symptoms, mild hypothyroidism, enlarged pituitary ...

A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma vegetative masses mitral tricuspid valve of heart. Both kidneys were severely enlarged, multiple yellow on parenchyma. Histopathologically, abscesses, endocarditis, suppurative glomerulonephritis, fibrino-purulent...

Author's response to reviews: We would like to express our sincere thanks to the reviewers for their positive comments. Replies to Reviewer 1: 1. Have you tried to understand relationship between heart rate or heart size and NMDA-receptor regulation, because Ketamine is a kind of NMDA receptor antagonist? Response: At the embryonic stage, NMDA-receptor expression is initiated during late cardia...

Prolonged juvenile hypothyroidism results in a permanent loss in height that is related to the duration of thyroxine deficiency before adequate thyroxine replacement treatment. A 13 year old girl with severe juvenile hypothyroidism was studied prospectively. She had an undetectable serum thyroxine concentration, a height SD score of -6.6 SD, and a bone age of 5.8 years. The enlarged pituitary g...

A 65-year-old woman with rheumatic heart disease and severe mitral stenosis developed dysphagia. As her dysphagia could not be directly attributed to an enlarged left atrium, she underwent barium swallow, which established the diagnosis of achalasia. This case report shows two unrelated diseases present in the same patient which individually can cause dysphagia.
