Differential diagnosis of Alzheimer's disease (AD) and vascular dementia(VaD) has an important bearing on the diagnosis and management of patients with dementia. This article provides a guideline for the differential diagnosis through 1) history taking, 2) neurological examination, 3) neuropsychological tests, and 4) neuroimaging studies. VaD consists of etiologically and clinically heterogeneous subtypes that include multi-infarct dementia (MID), single strategic infarct dementia, and subcortical vascular dementia. Patients with MID and single infarct dementia con be easily differentiated from patients with AD. However, clinical manifestations of subcortical vascular dementia can mimic those of AD, which may lead primary physicians to misdiagnose subcortical vascular dementia as AD. The issue of differential diagnosis is further complicated by the fact that many patients may have AD with concomitant VaD (mixed dementia).

A traumatic dislocation of the sternoclavicular joint is a rare injury, and among them, anterior dislocation is more common than a posterior dislocation. Posterior dislocation is a potential risk by compressing the mediastinal structures, but an anterior dislocation has not been considered a risk. Traumatic sternoclavicular joint anterior dislocation associated with anterior angulation of a sternal fracture can develop mediastinal compression and have a risk in the same way as a posterior dislocation. This case report is about a traumatic sternoclavicular joint anterior dislocation with a sternal fracture accompanied by mediastinal compression that was treated surgically using a plate and showed relatively good clinical results. This rare case is reported along with a review of the relevant literature.

BACKGROUND AND OBJECT: Cheiro-oral syndrome (COS) is characterized by a sensory disturbance in the unilateral hand and ipsilateral mouth corner. It is usually due to a lesion in the parietal cortex, thatamocortical projections, thalamus, or rarely brain stem. However, the syndrome is relatively unknown and rarely mentioned in most neurological textbooks. We presented ten cases of COS with a review of the clinical symptoms and signs and the neuroradiological methods used to demonstrate the responsible site. METHODS AND RESULTS: We studied 10 patients with stroke who showed restricted sensory disturbance on the one hand and ispilateral mouth. The study forms consisted of clinical manifestaion, neurological examination, electrophysiological, and neuroradiologic studies. Computed tomography and/or magnetic resonance imaging identified lesion in the thalamus in 5, brain stem in 3, and corona radiata in 1 patient. But, the anatomical responsible site for one case was not founded. Infarction had occurred in nine cases and hemorrhage in one. Seven of the 10 patients showed sensory disturbances restricted to the perioral area, hands, fingers when they were first examined; the remaining patients complained more diffuse sensory disturbances at first, but it had become restricted to perioral and fingers, usually within 2-3 weeks. The durations of symptom varied from 5 days to more than 15 months and these symptoms were improved within 2-3 weeks to 4 months in treated patients. CONCLUSION: When the symptoms and signs of the COS were presented, especially if a history of migraine is lacking, neuroradiological methods such as CT or MRI should be undertaken to localize and diffentiate the nature of lesion.

The pattern reversal visual evoked potential(PRVEP) and flash electroretinogram(flash ERG) were performed in 22 patients with optic atrophy. Patients with ophthalmologic problems other than optic atrophy or with systemic disorders were excluded from the analysis The results are as follows: 1. In the 41 eyes of patients with optic atrophy, 39 of them showed abnormal PRVEP, in which all the eyes had no consistent waveform except in one patient 2 eyes with delayed P1 latency. 2. 13 eyes were abnormal in both PRVEP and flash ERG but no eye was abnomnal in flash ERG only 3, Regarding the flash ERG examination, 13 eyes were abnomlal. Of these, there was a period of 1 to 2 years for 1 eye's disease, a period of 2 to 5 years for another eye' disease and after 5 years 11 eyes were diseased. Therefore, it showed that the longer the duration of disease lasted, the more flash ERG abnormalities developed. 4. The abnormalities of PRVEP haxe no significant relationship with the duration of the disease.

We have had an opportunity to study a patient with acute sensory neuronopathy. The patient was a 32-yearold housewife; the rapidly spreaded tingling sensation along both arms and legs developed, rendering her severely ataxic. There was no history of antecedent illness, familial neurological disease, or exposure to toxins and special drugs. On examinations, there was no abnormality in her mental and cranial nerve function. There was no motor weakness. She showed the profound loss of kinesthetic sense which was acutely progressive and associated with severe sensory ataxia and pseudoathetosis. All tendon reflexes were absent. However, cutaneous senses were preserved. There was no significant abnormal laboratory finding except elevated CSF protein content. On electrophysiologic findings, the decrease in the amplitude of action potentials with only mild slowing of conduction velocities of sensory nerves were found even though motor nerve conduction studies were normal. Median and tibial somatosensory evoked potentials could be elicited, although the median N19 scalp response and tibial N45 waveforms were prolonged in latency. Plasmapheresis were provided; clinical features improved. However, the electrophy-siological abnormalites remained. Thus we wish to report an additional case of woman suffering from the acute sensory neuronopathy, complementing the cases described by Stemm, Schaumburg and Asbury.

Purpose: Surgery is prioritized for a splenic injury when the patient is hemodynamically unstable or the injury is severe and there is an increased risk of bleeding. This study aimed to examine the outcomes of splenectomies where a surgical stapling device was used to reduce operation time and rapidly control bleeding. Methods: This retrospective study included 53 patients who underwent a splenectomy for traumatic splenic injury at Chosun University Hospital between 2012 and 2017. Clinical outcomes including operation time (duration), blood transfusion amount (number of units), length of hospital stay, length of intensive care unit stay, and mortality rate were compared between patients who received conventional ligation [conventional group (CG)] and patients who received a splenectomy where a surgical stapling device was used [stapling group (SG)]. Results: The SG showed an average operation time of 17 minutes less than the CG, although the reduction was not statistically significant. No significant differences in estimated blood loss and blood transfusion amount were determined between the 2 groups, although the SG received 1 more unit of red blood cells for transfusion in the 48-hour post-operative period compared with the CG. One case of pancreatic fistula as a postoperative complication was reported in the SG. Conclusion The use of a surgical stapling device in a splenectomy may be considered for a hemodynamically unstable patient with splenic injury which caused severe anatomical damage.

PURPOSE: We evaluated whether Cyberknife radiosurgery is an effective and safe method of therapy for medically intractable trigeminal neuralgia (TN). MATERIALS AND METHODS: We retrospectively analyzed the outcome of 26 patients, who failed to surgery or were not suitable candidates for invasive intervention and were treated by Cyberknife radiosurgery between March 2004 and May 2005. Radiosurgery doses of 60~64 Gy were delivered to the 80% isodose line prescribed to an 6 mm length of the nerve, sparing the most proximal 3 mm away from the trigeminal nerve root entry zone (median dose: 64 Gy). RESULTS: Follow-up period was 3~15 months (median follow-up period: 9 months) Preliminary results from a cohort of 26 patients undergoing Cyberknife radiosurgery for TN showed that pain relief was achieved in 50% (13/26) of patients within the first 24 hrs after treatment. At last follow-up, 96.2% (25/26) of patients reported early pain relief within 7 days. Treatment failure developed in 2 of 26. Poor response occurred in one patient and relapse was observed in the other patient. 3 patients had hypoesthesia (11.5%), which was the only complication observed with any of our patients. CONCLUSION: With these results, authors assumed that Cyberknife radiosurgery for TN could be one of safe and effective therapeutic methods.
