Clinical and radiological features of hybrid surgery in multilevel cervical degenerative disc disease.

2015

Purpose: Although several studies have established the safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF), few studies have investigated the role of hybrid surgery (HS) that incorporates ACDF and CDA techniques in multilevel cervical degenerative disc disease (MLCDDD). Methods: This prospective study enrolled patients with MLCDDD who underwent HS. Twenty consecutive patients who underwent HS were compared with patients who underwent ACDF and CDA at the same level of surgery. Patients were followed up for more than 2 years. Intraoperative parameters, clinical features and outcome scores were recorded. Radiological assessments…

Magnetic resonance myelography evaluation of the lumbar spine end plates and intervertebral disks.

2005

Purpose: To evaluate the value of magnetic resonance (MR) myelography in the evaluation of intervertebral disk and end‐plate degenerative changes in the lumbar spine.Material and Methods: Conventional MR and MR myelography examinations were performed in 150 consecutive patients (69 F and 81 M, mean age 45±15 years, range 18–89). Sagittal T1 and T2‐weighted TSE images were compared to MR myelography obtained with a multishot‐TSE‐T2‐weighted sequence (4000/250/fat suppression). Coronal, sagittal, and both oblique MR myelography projections were obtained. Image analysis was carried out independently by two radiologists who categorized lumbar disks into normal, degenerated, or edematous; and ve…

Optical Coherence Tomography Angiography of Optic Disc in Eyes With Primary Open-angle Glaucoma and Normal-tension Glaucoma.

2019

PURPOSE To examine vessel density (VD) properties of the optic nerve head in eyes with ocular hypertension (OHT), high-tension glaucoma (HTG), and normal-tension glaucoma (NTG) and to evaluate associations on structural parameters of retinal nerve fiber layer (RNFL). METHODS Three groups of patients with OHT (n=15), HTG (n=36), and NTG (n=22), and a healthy control group (n=23) were included in this study. Peripapillary VD and optic disc flow area were measured using optical coherence tomography angiography, and peripapillary RNFL (pRNFL) thickness was determined. Global and sectoral analysis of optic nerve head vasculature and pRNFL thickness were measured. RESULTS Glaucomatous eyes had lo…

Optic disc drusen in tilted disc

2017

Purpose To investigate if a congenital anomaly of the head of the optic nerve like such as tilted disc can be a risk factor for the development of optic disc drusen. Methods The study was performed retrospectively on the files of 47 patients with optic disc drusen. The diagnosis was confirmed by fluorescein angiography and B-scan ultrasonography. The authors examined the fundus photographs and the fluorescein angiographies of these patients looking for the presence of tilted discs. Results Two of the 47 patients with optic nerve drusen had tilted discs as well, about twice the expected rate. Both cases presented a parapapillary hemorrhage. Conclusions The concomitant presence of tilted disc…

Quantifying the contribution of arm postural tremor to the outcome of goal-directed pointing task by displacement measures.

2004

A method for quantifying the outcome of goal-directed postural pointing was presented and used for relating the tremor output to the oscillations of single arm landmarks. The displacement of reflective markers placed on shoulder, upper arm, forearm, and hand were measured by an optoelectronic motion capture system in nine subjects holding a laser penlight pointed at a target. The high signal-to-noise ratio of the measured displacement series (from 7:1 for shoulder marker to 30:1 for hand marker) demonstrated the feasibility of the proposed system to carry out tremor analysis. The track of the laser emission on the target, reconstructed from penlight displacements, was studied as the outcome…

Late onset of unilateral optic disk edema secondary to treatment with imatinib mesylate

2017

Key Clinical Message Prompt ophthalmology evaluation and immediate imatinib suspension should be suggested at any time of tyrosine kinase inhibitor therapy in patients with visual deficit, as it may be a clinical manifestation of optic disk edema, and suspension may help in prompt recovery.

Sacīkstes princips civilprocesā

2018

Maģistra darba nosaukums ir "Sacīkstes princips civilprocesā". Sacīkstes princips ir viens no civilprocesa pamatprincipiem, proti, puses savas procesuālās tiesības īsteno sacīkstes formā, un tiesa lietu izspriež, vadoties no pušu iesniegtajiem pierādījumiem un izteiktajiem argumentiem. Sacīkstes princips ir pieskaitāms pie civilprocesa kopējiem jeb vispārējiem principiem, kura uzdevums ir nodrošināt likumības un līdztiesības ievērošanu nolēmumu pieņemšanas procesā, vienlaikus garantējot tiesneša neitralitāti un objektivitāti. Maģistra darba mērķis ir noskaidrot sacīkstes principa būtību un nepieciešamību civilprocesuālajās attiecībās, kā arī izpētīt Civilprocesa likuma 93. panta ceturtās da…

Meta-analysis of Genome-Wide Association Studies Identifies Novel Loci Associated With Optic Disc Morphology

2015

Primary open-angle glaucoma is the most common optic neuropathy and an important cause of irreversible blindness worldwide. The optic nerve head or optic disc is divided in two parts: a central cup (without nerve fibers) surrounded by the neuroretinal rim (containing axons of the retinal ganglion cells). The International Glaucoma Genetics Consortium conducted a meta-analysis of genome-wide association studies consisting of 17,248 individuals of European ancestry and 6,841 individuals of Asian ancestry. The outcomes of the genome-wide association studies were disc area and cup area. These specific measurements describe optic nerve morphology in another way than the vertical cup-disc ratio, …

Pušu procesuālās tiesības mantojuma lietās.

2019

Pēc mantojuma atstājēja nāves viņa statusu ieņem tā mantinieks, taču ne vienmēr katram atstātajam mantojumam ir mantinieki, kas vēlas pārņemt mantojuma atstājēja tiesības un saistības, un tādā gadījumā kreditori nevar vērst piedziņu pret mantiniekiem. Kreditori var lūgt izsludināt mantojuma atklāšanos un lūgt iecelt mantojuma masai aizgādni, taču tas ir laikietilpīgs process. Darba autore darbā izvirzījusi mērķi noskaidrot, vai mantojuma masas aizgādņa iecelšanas procesa ilgums neapgrūtina kreditoru intereses parāda piedzīšanas procesā. Darbs sastāv no trīs nodaļām, kurās sniegts mantojuma masas un procesuālo tiesību skaidrojums un izvērtēts, kā aizsargāt kreditoru intereses mantojuma lietā…
