Background Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. Methods A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. Results Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. Conclusions Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.

심장점액종은 심장의 가장 흔한 양성 종양이다. 하지만 국소전이와 원격전이의 증례들이 낮은 빈도로 보고되어 있다. 뇌경색을 주소로 내원한 49세 여자 환자의 심장초음파에서 심장 점액종이 발견되었으며 수술로 절제 1년 후에 구음장애가 발생하여 촬영한 자기공명영상에서 여러개의 조영증강이 되는 출혈성뇌전이 병변들이 관찰되었다. 방사선치료 후 추적 자기공명영상에서 병변의 크기들이 작아지는 것을 확인할 수 있었다. 양성 종양이지만 심장 점액종은 드물게 지연되어 전이를 보일 수 있다. 저자들은 심장 점액종을 수술로 완전히 절제 후 지연되어 나타난 뇌전이를 경험하여 증례 및 문헌고찰을 하는 바이다.

Background and Objectives : The Motor evoked potentials (MEP) study may be useful in the evaluation of the degree of impairment in the motor nervous system and in the determination of the prognosis. The purpose of this study is to evaluate the status of central nervous system in acute and subacute state of cerebral ischemia by comparing the changes of MEP in the initial and follow-up study. Methods : Twenty patients with hemiparesis caused by ischemic stroke were recruited for this study. We tested MEP within 7 days and followed-up after 14 days after symptom onset. The cerebral motor cortex area, cervical area for upper extremity and lumbar area for lower extremity were stimulated by transmagnetic stimulator. The central motor conduction time(CMCT) was measured with the difference in MEP caused by stimulating the vertical area and spinal area. The CMCT of hemiparetic patients were classified into three groups-normal, delayed, and no evoked MEP groups. Results : The CMCT in hemiparetic side of acute ischemic stroke patients were singnificantly delayed (P < 0.05) compared with the control group. The CMCT of hemiparetic side in the follow-up study showed no sinificantly difference in comparison to the control group. The prognosis of motor improvement was better in the groups of delayed MEP than the groups of no evoked MEP. Conclusion : The CMCT of hemiparetic and contralateral sides were delayed in acute ischemic stroke, compared with control group and were returned to normal boundaries in subacute state. But in the most cases with no MEP response in the initial study, also showed no MEP response in the follow-up study. The recovery occurred in the subacute state in cases with mild hemiparesis, whereas recovery did not occur in the subacute stage in case with severe hemiparesis.

Objectives : This study was designed to investigate significant differences between the first attack and reattack groups to form fundamental data for decreasing recurrence and secondary prevention of stroke. Methods : I studied 204 patients admitted within 7 days of onset, after the diagnosis of stroke, in the Oriental Medical Hospital of Dongeui University from February to July in 2001.compared the reattack group with the first attack group for risk factors, clinical symptoms and progress, average mark and degree of improvement in Activity Index. Results : 1. Meaningful risk factors associated with the reattack group were male sex, a past history of hypertension and transient ischemic attack, and a family history of stroke. 2. The reattack group had conscious or cognitive disorder in early stage of onset, dysphagia, constipation, urinary incontinence, visual field defect in acute stage, high blood pressure and tachycardia in abnormalvital sign in acute stage, neuropsychosis, shoulder pain and rigidity, and pneumonia in complications more than the first attack group. 3. In Activity Index, the average mark of reattack group was lower than that of the first stroke group and improvement of the reattack group was delayed compared with the first attack group. Conclusions : The reattack group had more severe symptoms and clinical progress than the first attack group.

We investigate the molecular and cellular etiologies that underlie the deletion of the six amino acid residues (${\Delta}F323-Y328$; ${\Delta}FY$) in human torsin A (HtorA). The most common and severe mutation involved with early-onset torsion dystonia is a glutamic acid deletion (${\Delta}E$ 302/303; ${\Delta}E$) in HtorA which induces protein aggregates in neurons and cells. Even though ${\Delta}FY$ HtorA forms no protein clusters, flies expressing ${\Delta}FY$ HtorA in neurons or muscles manifested a similar but delayed onset of adult locomotor disability compared with flies expressing ${\Delta}E$ in HtorA. In addition, flies expressing ${\Delta}FY$ HtorA had fewer aberrant ultrastructures at synapses compared with flies expressing ${\Delta}E$ HtorA. Taken together, the ${\Delta}FY$ mutation in HtorA may be responsible for behavioral and anatomical aberrations in Drosophila.

Tolosa-Hunt syndrome is a rare self-limiting disease that's characterized by painful ophthalmoplegia. It has a relapsing and remitting course, and the pain responds promptly to systemic corticosteroid therapy. Yet it is diagnosed by the exclusion of other major causes involving the superior orbital fissure or cavernous sinus, including trauma, neoplasm, aneurysm and inflammation. Further, the associated ophthalmoplegia may follow days to weeks after the onset of orbital or hemifacial pain. Hence, this condition is often misdiagnosed as atypical facial pain, and so improper management could result in unnecessary suffering of the patient. The following case describes a patient suffering with hemifacial pain associated with ipsilateral abducens nerve palsy, which was evident 2 weeks after the onset of pain, and this was misdiagnosed as trigeminal neuralgia and atypical facial pain.

The majority of clinical studies on moyamoya disease (MMD) have focused on anterior circulation. The disease involvement of posterior circulation in MMD, mainly in the posterior cerebral artery (PCA), has been mentioned since the early 1980s, and it has been repeatedly emphasized as one of the most important factors related to poor prognosis in MMD. However, its clinical features and outcome have only been elucidated during the last few years. In this review, the angiographic definition of PCA stenosis is summarized. The clinical features are elucidated as being either early-onset or delayed-onset, according to the time of PCA stenosis diagnosis in reference to the anterior circulation revascularization surgeries. The surgical strategy and hypothesis on the mechanism of PCA stenosis is also briefly mentioned. It appears that some MMD patients may show PCA stenosis during the early or late course of the disease and that the presenting symptoms may vary. Because the hemodynamic compromise caused by PCA stenosis may respond well to surgical treatment, clinicians should be aware of the condition, especially during follow-up of MMD patients.

The quantitative sudomotor axon reflex testing (QSART) is a classic test of routine postganglionic sudomotor function. We investigated sudomotor function by QSART after summer (July 2012) and winter (January 2013) seasonal acclimation (SA) in the Republic of Korea. QSART with acetylcholine (ACh) iontophoresis were performed to determine directly activated (DIR) and axon reflex-mediated (AXR1, 2) sweating rate. Onset time of axon reflex, activated sweat gland density (ASGD), activated sweat gland output (ASGO), tympanic and skin temperatures ($T_{ty}$, $T_{sk}$), basal metabolic rate (BMR), and evaporative loss volume changes were measured. Tympanic and mean body temperature (${\bar{T}}_b$; calculated from $T_{ty}$, $T_{sk}$) were significantly lower after summer-SA than that of winter-SA. Sweat onset time was delayed during winter-SA compared to that after summer-SA. BMR, AXR(1), AXR(2), and DIR sweat rates, ASGD and ASGO, and evaporative loss volume were significantly diminished after winter-SA relative to after summer-SA. In conclusion, changes in sweating activity measured by QSART confirmed the involvement of the peripheral nervous system in variation of sudomotor activity in seasonal acclimation.

Objectives : This study was performed to find the relation between prognosis of peripheral facial palsy and blink reflex. Methods : Data was collected from patients who were admitted and treated by East-West Collaborative Treatment of Facial Palsy Center in Kyung Hee University Hospital at Gangdong from January 2012 to June 2013. Patients were screened by inclusion/exclusion criteria and 163 patients' medical records were reviewed including blink reflex performed $14{\pm}2$ days after onset and House-Brackmann grade. Patients were divided into three groups, normal, delayed and absent group by blink reflex test. Trends of each recovery rate to House-Brackmann grade II and I depending on three group were analyzed at 1 month, 3 months and 6 months after onset using Linear by linear association. Results : At 1 month, 3 months and 6 months after onset, both recovery rate to House-Brackmann grade II and I had a tendency to be decreased statistically significantly in order of normal, delayed and absent group. Conclusions : We could find feasibility of blink reflex as a prognostic factor of peripheral facial palsy. Further study will be necessary.
