Only few tissues lack lymphatic supply, such as the CNS or the inner eye. However, if the scleral border is compromised due to trauma or tumor, lymphatics are detected in the eye. Since the situation in the optic nerve (ON), part of the CNS, is not clear, the aim of this study is to screen for the presence of lymphatic markers in the healthy and lesioned ON. Brown Norway rats received an unilateral optic nerve crush (ONC) with defined force, leaving the dura intact. Lesioned ONs and unlesioned contralateral controls were analyzed 7 days (n = 5) and 14 days (n = 5) after ONC, with the following markers: PDGFRb (pericyte), Iba1 (microglia), CD68 (macrophages), RECA (endothelial cell), GFAP (astrocyte) as well as LYVE-1 and podoplanin (PDPN; lymphatic markers)...

Teratoma is a rare tumor, containing structures originating from all three germinal layers. The most frequent location of teratoma is the gonads. Orbital teratoma is extremely rare. In 1969, Jensen reported that only 40 cases of orbital teratoma existed in the world. We describe a rare case of orbital teratoma in a 15-day girl who presented with marked proptosis of the left eye. The eyeball was embedded within the mass that could be seen all around the globe. Orbitectomy was performed with the impression of retinoblastoma...

Uterine leiomyomas are the most common benign smooth muscle cell tumors in women. Estrogen (E2), progesterone (P4) and environmental factors play important roles in the development of these tumors. New treatments, such as mifepristone, have been proposed. We evaluated the gene expression of total (PRT) and B (PRB) progesterone receptors, and the histone acetyltransferase (HAT) and deacetylase (HDAC) activity after treatment with E2, P4 and mifepristone (RU486) in primary cell cultures from uterine leiomyoma and normal myometrium...

Isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. This report describes a 61 years old female with an abrasion on the left forehead and ptosis of the left eye. Initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. High-resolution and multi-axial enhanced Magnetic resonance imaging (MRI) can be helpful in diagnosis and monitoring of patients with this rare phenomenon.

Psoriatic arthritis (PsA) is a heterogeneous chronic inflammatory disease with a broad clinical spectrum and variable course. It can involve musculoskeletal structures as well as skin, nails, eyes, and gut. The management of PsA has changed tremendously in the last decade, thanks to an earlier diagnosis, an advancement in pharmacological therapies, and a wider application of a multidisciplinary approach. The commercialization of tumor necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, and infliximab) as well as interleukin (IL)-12/23 (ustekinumab) and IL-17 (secukinumab) inhibitors is representative of a revolution in the treatment of PsA...

We report the first documented case of retrobulbar optic neuropathy associated with golimumab. A 48-year-old man was admitted with a 3-week history of progressive visual loss of his left eye. He had received a second infusion of golimumab for ankylosing spondylitis 10 days before admission. A magnetic resonance imaging scan showed enhancement of both optic nerves and visual evoked potentials were consistent with demyelinating bilateral optic neuropathy, although visual acuity drop in the right eye could not be determined because of deep amblyopia...
