Hyaline cells are non-sensory epithelial cells of the vibrating part of the basilar membrane of chicks; they receive an extensive efferent innervation. Although these anatomical features suggest roles in auditory transduction, very little is known about the function of these cells. One possible way to understand function is by lesion experiments. We used synapsin-specific antibodies to study ch...

PURPOSE To investigate the prevalence of scleral hyaline plaque among older adults in the city of Niterói in southeastern Brazil. A second goal was to assess the correlation between scleral hyaline plaque and several age-related diseases, including eye diseases and systemic diseases. METHODS The study sample comprised 667 participants who were followed for 15 months. The study had a prospecti...

Mallory-Weiss tearing (MWT) is a common cause of non-variceal upper gastrointestinal bleeding. Although the majority of patients with bleeding MWT require no intervention other than hemodynamic supports, spectrum of MWT is wide, and the condition sometimes results in a fatal outcome. Endoscopic management to stop the bleeding may be required during the index endoscopy, especially in those with ...

Representative portions of lung from 17 newborn infants with hyaline membrane disease were studied. The consistent findings in the hyaline membranes of Schiff's positivity requiring periodic acid pretreatment, their autofluorescence between 350 and 400 nm, and the granular ultrastructure of the membrane matrix provided morphologic evidence for lipid peroxidation's having occurred in association...

We present a case of pulmonary hyalinizing granuloma (PHG). On light microscopy, the pulmonary nodular lesions consisted of extracellular, eosinophilic hyaline lamellae. Histochemical stains of the hyaline lamellae for amyloid were focally positive and the diagnosis of amyloidosis was seriously considered; however, on electron microscopic examination, the hyaline lamellae consisted of electrond...

We present a unique case of Boerhaave Syndrome that may highlight the spectrum of barotrauma from a Mallory-Weiss tear to full-thickness perforation. In this case, perforation only became evident following air insufflation at endoscopy.
