Active clinical trials for "Ganglion Cysts"

To investigate whether stellate ganglion block is helpful to brain protection during cranial aneurysm surgery

The purpose of this investigation is to evaluate the relationship between IOP fluctuation, RGC dysfunction, and optic nerve and retinal nerve fiber layer (RNFL) thickness changes in patients with glaucoma and ocular hypertension receiving latanoprost 0.005% versus placebo.

To investigate whether the stellate ganglion block is helpful in relieving cerebral vasospasm during aneurysmal coil embolism surgery. The effect was assessed by Transcranial Doppler (TCD).

RATIONALE: A stellate ganglion nerve block may help relieve symptoms of post-traumatic stress disorder (PTSD). PURPOSE: This pilot clinical trial is studying the efficacy of a stellate ganglion nerve block in veterans to reduce the symptoms of PTSD in relatively long-standing (Vietnam era) induced or relatively recently induced PTSD (from deployment in Afghanistan or Iraq as part of Operations Enduring Freedom (OEF), Iraqi Freedom (OIF), and New Dawn (OND).

Computer-aided image recognition will improve the technique of endoscopic ultrasound-celiac plexus block/celiac plexus neurolysis (EUS-CPB/CPN) and improved pain relief.

Basal ganglia are involved in the control of motor, cognitive and emotional behaviours. The aim of this study is to precisely evaluate patients with basal ganglia focal lesions both with or without loss of psychic-self activation.

Optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) is done before and after cataract extraction in patients with or without primary open angle glaucoma (POAG)

The transnasal sphenopalatine ganglion block(SPGB) is administered to patients with facial or head and neck pain. In the transnasal approach, the drip and topical methods are frequently used. We compared facial temperatures and VAS after transnasal SPGB.

The investigators reviewed retrospectively the patients that had received septorhinoplasty(SRP). 42 patients were included in the study. Demographic, clinical, surgical, and follow-up data were collected from clinical case notes. The patients that had received sphenopalatine ganglion block(SPGB) before the surgery included in the Block group (n:20) and the patients that had not received SPBG before the surgery included in the Control group (n:22). The postoperative pain(POP) scores, the amount of postoperative rescue analgesics that was used, and the postoperative nausea and vomiting(PONV) scores in the first 24 hours and, mean arterial pressure (MAP), the dose of Remifentanil that was used during the operation were compared between the groups.

Transsynaptic degeneration of the retinogeniculate pathways is well documented to occur in nonhuman primates when the cerebral lesion occurs even during adulthood. In case of humans, retrograde transsynaptic degeneration of the retinogeniculate pathways has been shown to occur following prenatal or perinatal lesions, but its occurrence after cerebral lesions in adults is considerable rare. It is, however, well established that retrograde transsynaptic degeneration affects other neural systems in humans even when the injury occurs during adulthood. Some histopathological evidence points to the possibility of transsynaptic degeneration of the retinogeniculate pathway in humans even when the lesion occurs in adults, but the clinical significance is unknown.' Purpose: To measure the retinal ganglion cell layer (GCL) in patients with visual field defects due to intracerebral processes. To correlate GCL with the localization and type of intracerebral lesion. To compare the GCL with the retinal nerve fibre layer (RNFL) to investigate, which of the 2 parameters is more sensitive to show retinal layer abnormalities. To correlate GCL with visual field defects and electrophysiological parameters.
