Purpose: To examine the fine anatomic structures between levator aponeurosis and Müller muscle in front of the tarsus. Materials and Methods: Postmortem specimens of 6 Chinese males (5 elderly men, aging from 68 to 86 years; 1 child, 10 years old) were used. A 3-μm thickness sagittal section of the central part of the upper eyelid was prepared, and the samples were examined microscopically by using hematoxylin–eosin, Masson trichrome, and anti-smooth muscle actin antibodies staining....

A 47-year-old man who presented with subacute binocular diplopia and a left head turn was found to have a right sixth nerve palsy and right optic disc edema. Radiologic imaging revealed a non-lytic right greater sphenoid wing mass with a dural tail, suggestive of a sphenoid wing meningioma. The patient underwent an orbitotomy with lesion biopsy; histopathologic analysis and subsequent imaging revealed the diagnosis of metastatic clear cell renal cell carcinoma. He developed new metastases despite...

Purpose: Lacrimal outflow imaging has been limited in clinical practice due to a combination of modality limitations and efficacy of clinical testing. Cone beam computed tomography dacryocystography (CBCT DCG) has certain advantages over other modalities that may enhance clinical utility. This study was intended to understand the relationships between symptoms, syringing and CBCT DCG in a population of patients presenting with tearing. Methods: Cross-sectional cohort study of adult...

Purpose: An anatomical and histological study of the conjoint fascial sheath of the levator and superior rectus (CFS) was carried out by using the cadavers for teaching. Methods: Three adult Asian cadaver heads fixed in formalin were used. The CFS was exposed by the same surgeon in each case. Then the CFS was observed and measured in vivo and ex vivo. And the CFS, the levator and the frontal muscle were removed from the same eye for histological study. Results: The CFS was...

Abstract Nanocomposite hydrogels that contain silver nanoparticles (AgNPs) are especially attractive for various biomedical applications (e.g., antimicrobial wound dressings, coatings and soft tissue implants) due to strong antimicrobial activity of released silver nanoparticles and/or ions over prolonged times. However, all potential biomedical products have to be thoroughly specified fulfilling strict safety requirements. Characterization of nanocomposites is additionally complicated...

Abstract Mycobacterium abscessus subsp. massiliense (Mycma) belongs to the Mycobacterium abscessus complex and is a rapidly growing non-tuberculous mycobacterium. The chronic pulmonary, skin, and soft tissue infections that it causes may be difficult to treat due to its intrinsic resistance to the commonly used antimicrobial drugs, making it a serious world public health problem. Iron is an essential nutrient for the growth of microorganisms; nonetheless,...
