Diffuse alveolar hemorrhage as an early complication of alemtuzumab treatment: A case report of a multiple sclerosis patient and an overview of 14 cases.

Alemtuzumab is effective in relapsing remitting multiple sclerosis (RRMS). Serious adverse events have led to a renewed safety reassessment by the European Medicines Agency (EMA), leading to an approval under strict conditions. We report a RRMS patient experiencing diffuse alveolar hemorrhage (DAH) on day 4 of her first alemtuzumab cycle. In addition, we present an overview of the cases of alemtuzumab-induced DAH that were included in EMA's review procedure, additional well documented cases reported to the EMA and those cases reported in the literature. Combining these cases revealed striking similarities. Importantly, DAH was an early complication. All RRMS patients with known outcome showed complete recovery.

Case 01-2017 - Primary vitreoretinal lymphoma (PVRL): report of a case and update of literature from 1942 to 2016.

Primary vitreoretinal lymphoma (PVRL), as a subset of primary central nervous system lymphoma (PCNSL), is a rare and fatal ocular malignancy. Most PVRL masquerades as chronic posterior uveitis, which makes the clinical diagnosis challenging. Vitreous cells, subretinal lesions and imaging techniques are essential for clinical diagnosis. Importantly, cytopathology/histopathology identification of malignant cells is the gold standard for the diagnosis of PVRL. In addition, molecular detection of immunoglobulin heavy chain (IgH) or T cell receptor (TCR) gene rearrangements, immunophenotyping for cell markers, and cytokine analysis of interleukine-10 elevation are often used as adjunct procedures. Current management of PVRL involves local radiation, intravitreal chemotherapy (methotrexate and rituximab), with or without systemic chemotherapy depending on the involvement of non-ocular tissues. In cases with concomitant PCNSL, systemic high-dose methotrexate/rituximab based therapy in conjunction with local therapy, whole brain radiotherapy and/or autologous stem cell transplantation is considered. Although PVRL normally responds well to initial treatment, high rates of relapse and CNS involvement usually lead to poor prognosis and limited survival. A professional team of medical experts in ophthalmologists, ocular pathologists, neuro-oncologists and hemato-oncologists is essential for optimizing patient management.

Basic principles in design of electrostimulating equipment with complex biotechnical coupling combining biotechnical feedback and biological feedback are formulated. Realization of these principles in one system leads to qualitatively new capacities of enhancing the efficiency of implemented rehabilitative measures, which is the basis of the designed multichannel electromyostimulation device MYOS having a complex biotechnical feedback, which is used to treat a number of central and peripheral motor disorders (paralyses, pareses), to correct movements, to learn motor skills during training, etc.
