PURPOSE To classify muscle fibers of human extraocular muscle (hEOM) and to compare them to previous studies on hEOM, as well as to nonhuman EOM classification schemes and skeletal muscle fiber types. METHODS Muscle fibers cut in different muscle planes were followed on consecutive cross sections and typed with regard to their oxidative profile in(More)
Carbocyanines (DiI, DiA, DiO) are able to travel along membranes by diffusion and therefore have been used as postmortem neuronal tracers in aldehyde-fixed tissues. Surprisingly, detailed data on the influence of different parameters on tracing distances are still missing. This study was carried out to optimize tracing procedures and to reveal the validity(More)
PURPOSE To analyze palisade endings and their end organs, the so-called innervated myotendinous cylinders (IMCs), of human extraocular muscle (EOM) in more detail and to clarify with the help of double-fluorescent labeling and electron microscopy whether terminals in IMCs are sensory, serving proprioception. METHODS EOMs obtained from a donated cadaver(More)
OBJECTIVE To describe fluorescein angiographic guidelines for the use of verteporfin therapy in patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) or other conditions based on 2-year vision outcomes from the Treatment of Age-Related Macular Degeneration With Photodynamic Therapy (TAP) Investigation(More)
Innervated myotendinous cylinders (IMCs) were for the first time described in a sheep extraocular muscle (EOMs). They were found at the distal myotendinous junction of a medial rectus and were investigated by light and transmission electron microscopy. The IMCs are enveloped by a multi-layered capsule of fibrocytes and each contains the terminal portion of(More)
PURPOSE To determine the value of diffusion-weighted MRI (DWI-MRI) for pretherapeutic imaging of fluorodeoxyglucose (FDG)-avid lymphoma and lymphoma with variable FDG avidity. EXPERIMENTAL DESIGN Treatment-naïve patients with lymphoma who were referred for whole-body staging were included in this prospective study. Group A included patients with FDG-avid(More)
PURPOSE To determine the value of diffusion-weighted MRI (DWI-MRI) for treatment response assessment in 2-[18F]fluoro-2-deoxy-D-glucose (FDG)-avid lymphoma. EXPERIMENTAL DESIGN Patients with FDG-avid Hodgkin (HL) or non-Hodgkin lymphoma (NHL) at pretherapeutic 18F-FDG-PET/CT, who had also undergone pretherapeutic whole-body DWI-MRI, were included in this(More)
Recently, the combination of rituximab and bendamustine (R-Benda) has been defined as highly active in patients with follicular lymphomas, but little is known about the efficacy of R-Benda in mucosa-associated lymphoid tissue (MALT) lymphoma. In a retrospective analysis, we have defined 14 patients with MALT lymphoma undergoing therapy with R-Benda. Seven(More)
BACKGROUND Mucosa-associated lymphoid tissue (MALT) lymphoma is among the most common forms of extranodal lymphomas, but little is known about subcutaneous involvement in patients with non-primary cutaneous marginal zone lymphomas. DESIGN AND METHODS Patients with MALT lymphoma diagnosed and treated at our institution between 1999 and 2010 were analyzed(More)
BACKGROUND This study was performed to reinvestigate the detailed anatomy of the connective tissues related to the levator palpebrae superioris (LPS). MATERIALS AND METHODS One hundred and twenty human orbits were prepared macroscopically or with the help of an operational microscope. Connective tissues related to the LPS were measured, removed, and(More)
