Although cerebrospinal fluid leakage is suggested as one of the causes of spontaneous intracranial hypotension, on]y a few cases with direct evidence of cerebrospinal fluid leakage on radionuclide cisternography have been reported in the literature Indirect evidences of cerebrospinal fluid leakage such as early visualization of the soft tissue and bladder or delayed migration of radiotracer have been observed in most patients with spontaneous intracranial hypotension. We report a case of spontaneous intracranial hypotension in which cerebrospinal fluid leakage was directly demonstrated by early dynamic imaging of spine on radionuclide cisternography. We suggest that early dynamic imaging of spine is an important adjunctive procedure in detecting cerebrospinal fluid leakage in patients with spontaneous intracranial hypotension.

BACKGROUND: To evaluate the clinical and functional outcomes of arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension, and investigate the radiologic and clinical benefits from the results. METHODS: We evaluated patients treated with arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension from November 2008 to September 2015. Fractures with displacement exceeding one-fourth of the anterior-articular surface or more than one-third of the posterior-articular surface in radiographic images were treated by surgery. Clinical assessment was conducted based on range of motion, Rowe score, and Constant score of injured arm and uninjured arm at last follow-up. RESULTS: Fifteen patients with Ideberg classification grade III, IV, and V glenoid fracture who underwent arthroscopic-assisted reduction using percutaneous screw fixation were retrospectively enrolled. There were no differences in clinical outcomes at final follow-up compared to uninjured arm. Bone union was seen in all cases within five months, and the average time to bone union was 15.2 weeks. Ankylosis in one case was observed as a postoperative complication, but the symptoms improved in response to physical therapy for six months. There was no failure of fixation and neurovascular complication. CONCLUSIONS: We identified acceptable results upon radiological and clinical assessment for the arthroscopic-assisted reduction and percutaneous fixation. For this reason, we believe the method is favorable for the treatment of Ideberg type III, IV, and V glenoid fractures. Restoration of the articular surface is considered to be more important than reduction of fractures reduction of the scapula body.

A clinically rare case of recurrent meningioma of the orbit of 30 years old male is reported. The right eye invaded with fibroblastic meningioma was enucleated in association of resection of tumor mass ten years ago. The second surgery of socket reconstruction for the palpebral and conjunctival atrophy was performed eight years later. An experience of orbital exenteration to a complete removal of walnut sized firm and palpable mass recurred in the orbital socket with successful result after the histo-pathological examination was described.

The surgical technique for removal of ruptured lumbar intervertebral disc has changed very little since it was introduced by Mixter and Barr in 1934. The technique of the interlaminar operation used by most neurosurgeons was used successfully in early cases to relieve the sciatica, but many patients were unable to return to heavy work because of low back pain. Cloward described a different surgical technique for removal of a ruptured lumbar intervertebral disc. The operation utilizes a transverse skin incision and a wide bilateral stlipping and retraction of fascia and muscles. The ligamentum flavum is not removed but detached and reflected medially in a flap. Only the bone margins of the adjacent facets are removed. A complete laminectomy is never done except for spondylolisthesis when the separate neural arch is disarticulated and removed. Using a "Vertebral Spreader", and interlaminar exposure is developed two to three times larger than that obtained y the "standard" technique. The advantages are obvious: 1. Both operations were done through a single transverse incision. A wider lateral exposure for the skin wound, being made parallel to the lumbar operation was possible and the normal skin lines, heals better with less scar. 2. The entire ligament is preserved, by separating its attachments from the lamina and reflecting in a flap, a larger opening into the spinal canal is obtained and the replaced flap protects the dura and prevents scarring. 3. Cloward recommends the use of a narrow, sharp chisel and hammer, but we used the spinal rongeurs including the Kerrison punch to remove part of the laminal edge. We leave the articular facets of the lumbar disc surgery because the articular facets are considered important major elements in the articulation of the vertebral joints, and as an essential bony surface to be used in posterior spinal fusion operation. 4. The routine use of intrathecal cortisone after lumbar disc operation has not been used in our cases because of increased pressure of the cerebrospinal fluid in modified prone position of the patient.

PURPOSE: To investigate the clinical features and risk factors of ischemic third, fourth, sixth cranial nerve palsy. METHODS: Retrospectively, we reviewed the medical records of 46 eyes of 46 patients who were diagnosed with ischemic third, fourth, sixth nerve palsy alone such as age of onset, risk factors, recovery rate and recovery time. RESULTS: The mean age of onset was 64.9 years. Of the 46 patients, 15 patients (32.6%) in third cranial nerve palsy group, 15 patients (32.6%) in fourth cranial nerve palsy group, 16 patients (34.8%) in sixth cranial nerve palsy group. The risk factor of hypertension in 30 patients (65.2%) was the most common than other risk factors such as diabetes, hyperlipidemia, elevated blood hematocrit, ischemic heart disease, left ventricular hypertrophy, smoking. The mean number of risk factors was 2.3 +/- 0.5 in third cranial nerve palsy group, 1.6 +/- 1.1 in sixth cranial nerve palsy group, 1.4 +/- 1.1 in fourth cranial nerve palsy group. Of the 46 patients, 42 patients (91.3%) were recovered. There was no significant difference in recovery rate by cranial nerve palsy. Recovery time of intracranial abnormalities group (10.5 +/- 2.9 weeks) in brain imaging study was late as compared with that of no intracranial abnormalities group (7.5 +/- 5.1 weeks). CONCLUSIONS: The overall recovery rate of isolated ischemic third, fourth, sixth cranial nerve was high. But if there are intracranial abnormalities in imaging study, it took a long time to recover. Also ischemic third cranial nerve palsy had multiple risk factors characteristically.

The patterns of the moir'e fringe were investigated in 178 modern Korean skulls (112 males and 66 females) using moir'e contourography. The analysis of fringe patterns was executed using image analyzer on the photographs taken from anterior, both lateral, posterior and superior aspects. In the anterior aspect, the center of fringe was the glabella. The cotyledon shape of fringe (type I) was the most frequently observed in males (77%), but reverse triangular shape (type II) and rhomboid shape of fringe (type III) were more frequently observed in females. In the lateral aspect, the euryon, the center of fringe, was located at higher (4 mm) and more lateral (3 mm) position in females than in males. The contour patterns were more irregular (type I) in males than in females where the stripes were arranged more concentrically (type II, III). In the posterior and superior aspects, there was no difference between males and females in the shape of fringe patterns. The relative position of the opisthocranion, the center of fringe in the posterior aspect, was high by 35 mm to eye -ear plane on the average in both sexes. The stripes in the superior aspect were arranged concentrically in both sexes, but wider in females than in males. The results of this nonmetrical study suggest that the analysis of the moir'e fringe patterns in the Korean skulls is a new method for sex discrimination in the field of forensic anthopology.

BACKGROUND: An acute ischemic infarction can occur in patients admitted to a nonneurology department, which can result in a delay in the diagnosis that could produce a poor outcome. The aim of this study was to identify the clinical and radiologic features of ischemic stroke diagnosed during consultations in nonneurology departments. METHODS: Acute ischemic stroke patients who were admitted to a neurology department or who were diagnosed after a consultation to a neurology department between October 2007 and February 2009 were enrolled. Acute ischemic stroke was diagnosed by a stroke neurologist with the aid of diffusion-weighted MRI. Clinical variables [age, sex, risk factors, initial score on the National Institutes of Health Stroke Scale, stroke subtype, and modified Rankin scale (mRS) score at 3 months] were obtained. Poor clinical outcome was defined as a mRS score of 3-6. Stroke lesion types based on MRI were classified into single vascular territory, multiple vascular territories, and multiple circulations. RESULTS: In total, 340 patients were enrolled, 84 (24.7%) of whom were diagnosed in nonneurology departments. Among the 84 consultations, 57 cases were symptomatic ischemic strokes, and 27 cases exhibited irrelevant acute ischemic lesions. With respect to the stroke subtype, other cause (10.7% vs 4.8%) and undetermined cause (42.9% vs 20.7%) were more common in the nonneurology department patients (p<0.0001). Acute ischemic strokes in multiple circulations were also more common in those from nonneurology departments (44.0% vs 11.0%, p<0.0001), along with higher high-sensitivity C-reactive protein levels. A poor clinical outcome was more common among patients in the nonneurology departments than among those in the neurology department (75.0% vs 27.5%, p<0.0001). CONCLUSIONS: Ischemic strokes from nonneurology departments tend to appear as nonlocalizing neurologic symptoms and spread in multiple circulations, and are associated with a worse outcome than those from neurology departments.
