Traumatic intracranial lesion has been one of the most frequent and serous problem in neurosurgical pathology. CT made it possible to get prompt diagnosis and surgical intervention of intracranial lesions by its safety, fastiness and accuracy. Computed tomographic scan was carried out on 1309 cases at Soonchunhyang Chunan Hospitalfor 15 months from Oct. 1983 to Dec. 1984. We have reviewed the computed tomographic scans of 264 patients whichshowed traumatic intracranial lesion. The results were as follows: 1. Head trauma was the most frequentlydiagnosed disase using computed tomographic scans(57.8%), and among 264 cases the most frequent mode of injury wastraffic accident (73.9%). 2. Skull fracture was accompained in frequency of 69.7% and it was detected in CT in38.6%: depression fractue was more easily detected in 81%. 3. Countercoup lesion(9.5%) was usually accompained with temporal and occipital fracture, and it appeared in lower incidence among pediatric group. 4. Intracranial lesions of all 264 cases were generalized cerebral swelling(24.6%), subdural hematoma(22.3%), epiduralhematoma(20.8%), intracerebral hematoma(6.1%), and subarachnoid hemorrhage(3.0%). 5. The shape of hematoma wasusually biconvex(92.7%) in acute epidural hematoma and cresentic(100%) in acute subdural hematoma, but the morechronic the cases became, they showed planoconvex and biconvex shapes. 6. Extra-axial hematoma was getting decreased in density as time gone by. 7. Hematoma density was not in direct proportion to serum hemoglobin levelas single factor.

Dystonia is a movement disorder characterized by involuntary contraction of muscles resulting in repetitive or twisting movements. Dystonia is generally caused by basal ganglia dysfunction.Recent studies have reported an association between dystonia and brainstem disorders. However, the pathological mechanism is uncertain, and detailed management strategies are limited. Here, we report a case of hemidystonia with abnormal posture and impaired proprioception after pontine hemorrhage that was effectively treated with pharmacotherapy combined with early intensive comprehensive rehabilitation. A 45-year-old man presented with abnormal posture and dystonic movement in the right hand and foot after a pontine hemorrhagic stroke. Pharmacotherapy with clonazepam and benztropine was administered, and comprehensive rehabilitation programs were implemented intensively from the early stages of symptom onset. After 3 months, the patient was able to walk independently, go up and down a few stairs without the use of a handrail, and was able to perform activities of daily living with minimal assistance.

Purpose:
This study aimed to analyze the profiles and mechanisms of injuries using online injury surveillance system (OISS) with match video files at 2017 World Taekowndo Championship (WTC) athletes.
Methods:
This study design was a prospective epidemiological study with video analysis. All injuries were recorded during the 2017 WTC using the OISS developed by the International Olympic Committee. A total of 971 athletes who participated in the 2017 WTC were enrolled. Each injury was recorded retrospectively by three cameras surrounding each court. Injury profiles and mechanisms were calculated as; percent injury rate, injury rate/100 athlete-exposures, injury location, type, and mechanism via the injury surveillance system and video analysis form.
Results:
There were 74 injuries, which corresponded to an overall incidence of 13.5 injuries (95% confidence interval, 11.2–15.8) per 100 athletes. The face (27.0%), hand/finger (23.0%), knee (14.9%), and ankle (10.8%) were most frequently injured parts. Contusions (37.8%), fracture and ligament sprains (20.3%) were the most frequently injury types. The main mechanism for contact injury is while attacking with the roundhouse kick (66.2%), or not used block (81.1%). There were also noncontact injuries (24.3%).
Conclusion
The incidence of injuries to the face, hand/fingers, knee, and ankle was relatively high. To prevent contact injuries, protective headgear and better shin guards and hand protectors need to be developed. As for the noncontact injuries, we recommend hamstring strengthening exercises, and neuromuscular training to strengthen the tendons and ligaments protecting the ankle and knee joints.

High frequency ventilation considerably reduces the risk of barotrauma due to low peak airway pressure compared to conventional mechanical ventilation. This risk, however, is also preaent with high frequency jet ventilation (HFJV) if excessive driving preasure are used and, above all if expiration is impeded. We investigated the effects of outflow resistance, which was varied by connecting different size of tube (ID 8.0, 7.5, 7.0, 6.5, 5.5, 5.0, 4.5, 4.0 mm), which was cut in 10 cm length, to the proximal site of endotracheal tube (ID 8.0 mm), which was inserted into the trachea of anesthetized dogs with a attached airway pressure monitoring catheter externally, in different driving pressure (2 kg/cm2, 1 kg/cm2) and frequency (100beats/min, 200beats/min) on the intra-airway preesure during HFJV. HFJV was performed with a catheter (diameter 2.5 mm) which was inaerted through endotracheal tube and located 1 cm proximal to the tip of endotracheal tube. Intra-airway pressure was acutely increased with the tube size of smaller than 5.5 mm in driving pressure 2 kg/cm2 and 5.0 mm in driving pressure 1 kg/cm2 compared to previous size of tube. 2 kg/cm2 of driving pressure showed significant higher airway pressure compared to 1 kg/cm in any size of tube. There was no difference in airway pressure by varing of frequency with same driving preasure. In summary, pulmonary barotrauma due to higher airway pressure may be occur if HFJV catheter occupied more than 25% of outflow tract area especially in higher driving pressure.
