Objective : To evaluate the clinical characteristics and surgical outcomes of the patients with cervical spondylotic myelopathy associated with athetoid cerebral palsy. Methods : The authors reviewed the clinical and neurodiagnostic findings, surgical managements and outcomes in six consecutive patients with cervical spondylotic myelopathy associated with athetoid cerebral palsy who had been treated with surgical decompression and fusion procedures between January 1999 and December 2005. The mean age of the 6 patients (four women and two men) at the time of surgery was 42.8 years (range, 31-55 years). The mean follow-up period was 56.5 months (range, 17-112 months). The neurological outcome was evaluated before and after operations (immediately, 6 months after and final follow-up) using grading systems of the walking ability, brachialgia and deltoid power. Results : At immediate postoperative period, after 6 months, and at final follow-up, all patients showed apparent clinical improvements in walking ability, upper extremity pain and deltoid muscle strength. Late neurological deterioration was not seen during follow-up periods. There were no serious complications related to surgery. Conclusion : Surgical decompression and stabilization in patients with cervical spondylotic myelopathy associated with athetoid cerebral palsy have been challenging procedure up to now. Our results indicate that early diagnosis and appropriate surgical procedure can effectively improve the clinical symptoms and neurological function in patients with cervical spondylotic myelopathy and athetoid cerebral palsy, even in those with severe involuntary movements.

Objective : Massive cerebral infarction could be accompanied by severe brain swelling and death secondary to transtentorial herniation. Approximately 10% to 15% of middle cerebral artery infarctions are associated with this phenomenon. However, the effectiveness and timing of decompressive surgery are still controversial. In this study, we present our results on the effect of decompressive craniectomy in life threatening cerebral infarction. Method : We retrospectively analyzed 15 patients who underwent decompressive craniectomy for massive cerebral infarction from January 1997 to April 1999. Surgical indication was based on the clinical signs such as neurological deterioration, pupillary reflex, and radiological findings. Clinical outcome was assessed by Glasgow Outcome Scale (GOS). Results : All 15 patients(five men, ten women ; mean age, 52.3 years ; right 11, left 4) were treated with wide craniectomy and duroplasty. The average time interval between onset of symptom and surgical decompression was 2.9 days. Clinical signs of uncal herniation(anisocoria, or fixed and dilated pupils) were presented in 13 of 15 patients. Mean Glasgow coma scale(GCS) was 12.4 points on admission, 8.1 points on preoperative state and 11.8 points postoperatively. Overall outcomes were favorable in 5 cases(Glasgow outcome scale : GOS I, II), unfavorable in 6 cases(Glasgow outcome scale : GOS III, IV) and dead in 4 cases. Conclusion : Early decompressive craniectomy before brain stem compression is considered as an effective lifesaving procedure for massive cerebral infarction unresponsive to aggressive medical therapy.

Purpose: To report our opinions of management about avascular necrosis following operative treatment of talar fracture and dislocation. Materials and Methods: We followed up 5 patients who were diagnosed as talar avascular necrosis after operation of talar fracture and dislocation. Clinical and radiological analysis were performed. The mean age of patients was 36 years. There were 4 males and 1 females. The average follow up was 51 months. Hawkins scoring system was used as clinical evaluation. Results: Regardless of radiological sclerotic finding, all patients showed satisfactory clinical result. Despite arthritic change in one patient, there were no further radiological and clinical deterioration to require salvage procedure. Conclusion: Most avascular necrosis after operative treatment of talar fracture and dislocation showed satisfactory result with conservative treatment. Thus, salvage operation such as talectomy or ankle fusion should be reserved in cases of intractable ankle pain and claudication.

Objective : This is retrospective study of clinical and radiological outcomes of anterior cervical fusion using Bongros-$HA^{TM}$ (BioAlpha, Seongnam, Korea) which is a type of synthetic hydroxyapatite (HA) spacer to evaluate the efficacy in its clinical application and usefulness as a reliable alternative to autograft bone. Methods : Twenty-nine patients were enrolled in this study and 40 segments were involved. All patients were performed anterior cervical interbody fusion using HA spacer and plating system. Indications for surgery were radiculopathy caused by soft-disc herniation or spondylosis in 18 patients, spondylotic myelopathy in 1 patient, and spinal trauma in 10 patients. Cervical spine radiographs were obtained on postoperative 1day, 1week, and then at 1, 2, 6, and 12 months in all patients to evaluate intervertebral disc height, and the degrees of lordosis. Cervical computed tomography was done at postoperative 12 month in all patients to confirm the fusion status. The mean period of clinical follow-up was 17 months. Results : Complete interbody fusion was achieved in 100% of patients. Preoperative kyphotic deformities were corrected in all cases after surgery. Intervertebral disc height was well maintained during follow up period. There were no cases of graft extrusion, graft deterioration and graft fracture. Conclusion : HA spacer is very efficient in achieving cervical fusion, maintaining intervertebral disc height, and restoring lordosis. When combined with the placement of a cervical plate, immediate stability can be achieved and graft related complication can be prevented.

Objective : To evaluate the clinical results of gross total resection in the surgical approach to spinal ependymoma. Methods : Between June 1995 and May 2009,13 males and 8 females (mean age 34) diagnosed with intramedullary or extramedullary spinal ependymoma were surgically treated at our centre. The neurological and functional state of each patient were evaluated according to the modified McCormick scale. Results : The average follow-up duration was 54 months (ranging from 12 to 168 months). The locations of the lesions were : thoracic region (4, 19%), lumbar region (7, 34%), cervical region (4, 19%), cervicothoracic region (3, 14%) and conus medullaris (3, 14%). Four patients (19%) had deterioration of neurological function in the early postoperative period. The neurological function of three patients was completely recovered at the 6th postoperative month, while that of another patient was recovered at the 14th month. In the last assessment of neurological function, 20 patients (95%) were assessed as McCormick grade 1. No perioperative complications developed in any of our patients. In one patient's 24-month assessment, tumour recurrence was observed. Re-operation was not performed and the patient was taken under observation. Conclusion : Two determinants of good clinical results after spinal ependymoma surgery are a gross total resection of the tumour and a good neurological condition before the operation. Although neurological deficits in the early postoperative period can develop as a result of gross total tumour resection, significant improvement is observed six months after the operation.

Purpose: Alport syndrome (AS) is one of the most common inherited renal diseases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term deterioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies.

Background: As social problems due to the acceleration of the aging era and the increase in the elderly population are becoming serious, virtual reality (VR)-based healthcare is emerging as an approach for preventing and managing health issues. Objects: This study used validity and reliability analyses to examine the clinical efficacy that is, the clinical value and usability of a novel VR cognitive evaluation system index that we developed. Methods: We developed a VR cognitive evaluation system based on motion recognition analysis evaluation for individuals aged 65 to 85. After conducting the Korean version of the Mini-Mental State Exam (K-MMSE) cognitive evaluation, the evaluation score was verified through correlation analysis in the VR cognitive evaluation system. To verify the construct validity of the two groups, the Global Deterioration Scale (GDS) grades were categorized into a normal cognitive group (GDS grade 1) and a cognitive impairment group (GDS grades 2 and 3). The data were measured twice to determine the reliability between the two measurements and assess the stability and clinical value of the evaluation system. Results: Our evaluation system had a high correlation of 0.85 with the widely used K-MMSE cognitive evaluation. The system had strong criterion-related validity at the 95% confidence interval. Compared to the average score of GDS grade 1 in the VR cognitive evaluation system, the average score of GDS grades 2 and 3 in the VR cognitive evaluation system was statistically significantly lower while also having strong construct validity at the 95% confidence interval. To measure the reliability of the VR cognitive evaluation system, tests-retests were conducted using the intraclass correlation coefficient (3,1), which equaled 0.923 and was statistically significant. Conclusion: The VR cognitive evaluation system we developed is a valid and reliable clinical tool to distinguish between normal cognitive status and mild cognitive impairment.

After initial recovery from acute carbon monoxide(CO) intoxication, some patients occasionally undergo severe neuropsychiatric deterioration, which is called postanomic delayed encephalopathy(sequelae). This is the clinical study about one patient, a 53-year-old woman, diagnosed with delayed encephalopathy after acute CO intoxication. The patient's symptoms were mental dysfunction including memory impairment and disorientation, aphasia, atrophy and weakness throughtout the body. She had completely recovered after an anomic episode, but the neurological symptoms that developed were preceded by an interval of apparent nomality.(the 'lucid interval'). She was characterized as suffering deficiency syndrome of the heart(心虛) and was prescribed for her an Ansinschungnoi-tang(安神淸腦湯), and thereafter her symptoms improved remarkably. For the evaluation of clinical improvement, we use the Modified Barthel Index(MBI).

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.

Background: Extracorporeal life support (ECLS) can be applied in brain-dead donors for organ perfusion before donation, thereby expanding the donor pool. The aim of this study was to examine the benefits and early clinical outcomes of ECLS for organ preservation. Methods: Between June 2012 and April 2017, 9 patients received ECLS with therapeutic intent or for organ preservation. The following data were collected: demographics, purpose and duration of ECLS, cause of death, dose of vasoactive drugs, and need for temporary dialysis before organ retrieval. The early clinical outcomes of recipients were studied, as well as survival and graft function at 1 month. Results: ECLS was initiated for extracorporeal cardiopulmonary resuscitation in 5 patients. The other patients needed ECLS due to hemodynamic deterioration during the assessment of brain death. We successfully retrieved 18 kidneys, 7 livers, and 1 heart from 9 donors. All organs were transplanted and none were discarded. Only 1 case of delayed kidney graft function was noted, and all 26 recipients were discharged without any significant complications. Conclusion: The benefits of protecting the vital organs of donors is significant, and ECLS for organ preservation can be widely used in the transplantation field.
