Differentiation of branchial cleft cysts and malignant cystic adenopathy of pharyngeal origin.

Objective: There is an increasing incidence of head and neck cancers that present as neck masses in a nonsmoking nondrinking population. These masses can be confused with benign cystic neck masses. The purpose of this study was to determine imaging criteria to differentiate benign lateral neck cysts from malignant cystic adenopathy.

Differential microRNA epression in asthma and the role of miR-1248 in regulation of IL-5.

Asthma is a chronic inflammatory disease that can be difficult to manage due to a lack of diagnostic biomarkers and an incomplete understanding of the molecular pathogenesis. MicroRNAs (miRNAs) are small, single-stranded, non-coding RNAs with increasing importance in regulation of immune function and as biomarkers. We profiled miRNAs in the serum of asthmatics and non-asthmatic controls to identify miRNAs that could serve as diagnostic markers and potential regulators of allergic inflammation.

Both coordination and symmetry of arm swing are reduced in Parkinson's disease.

Objective: A recent study reporting significantly reduced symmetry in arm swing amplitude in early Parkinson's disease (PD), as measured during single strides in a gait laboratory, led to this investigation of arm swing symmetry and coordination over many strides using wearable accelerometers in PD.

Methods: Forearm accelerations were recorded while eight early PD subjects and eight Controls performed 8-min walking trials. Arm swing asymmetry (ASA), maximal cross-correlation (MXC), and instantaneous relative phase (IRP) of bilateral arm swing were compared between PD and Controls.

Familial Creutzfeldt-Jakob disease presenting as epilepsia partialis continua.

Creutzfeldt-Jakob disease (CJD) is a rare disorder caused by prions that can affect any part of the central nervous system. It is characterized by a long incubation period, but once symptoms start there is a progressive neurological decline. Clinical features include dementia, ataxia and myoclonus (startle), among others.

Liver enzyme elevation and normal pulmonary function in an adult with a declining forced expiratory volume in 1 second.

This article presents a case report of a 41-year-old male firefighter with cholecystitis and a history of mildly elevated alanine aminotransferase. Liver biopsy showed periodic acid Schiff-positive, diastase-resistant periportal globules. Retrospective review of clinical data revealed progressive lung function decline despite absent pulmonary symptoms and normal pulmonary function testing.

The Harris-Benedict studies of human basal metabolism: history and limitations.

In the early part of the 20th century, numerous studies of human basal metabolism were conducted at the Nutrition Laboratory of the Carnegie Institution of Washington in Boston, Mass, under the direction of Francis G. Benedict. Prediction equations for basal energy expenditure (BEE) were developed from these studies.
