■ Objectives The goal of this pilot study is to observe the change of stroke gait by auditory cue training. ■ Methods An intracranial hemorrhage patient was trained for 4 weeks. For the 1^st consecutive 6days(the 1^st week), the patient was trained to walk with auditory cue, what was called auditory cue gait training condition. For the 2^nd consecutive 6days(the 2^nd week), the patient was trained to walk naturally without auditory cue, what was called free gait training condition. For the 3^rd consecutive 6days(the 3^rd week), the patient was trained to walk under auditory cue gait training condition. For the 4^th consecutive 6days(the 4^th week), the patient was trained to walk under free gait training condition. We analyzed the gait using a treadmill gait analysis system 3 hours after the 6^th gait training. ■ Results Auditory cue gait training showed effects on gait parameters, which were increasing walking velocity, step length, stride length, decreasing cadence, step time and stride time. ■ Conclusion Auditory cue gait training improved gait parameters of a stroke patient.

This study aimed to analyze patients hospitalized for injuries who fell using the data from 2020 to 2021 at institution A located in Gangneung-si, Gangwon-do, using codes for causes of injury. After classifying 20 codes from W00 to W19, which are external cause codes for fall patients, the most frequently occurring W18, W01, W10, and W13 were analyzed. The external cause of injury code W18 was other falls on the same plane, with the highest frequency of S72 and Z47, S72 being a fracture of the femur, and Z47 being orthopedic follow-up treatment. The external injury code W01 was determined to be a fall on the same plane due to slipping, tripping, and tripping, and like W18, S72, a fracture of the femur, and Z47, orthopedic follow-up treatment, were frequently reported. In W10, intracranial injuries such as concussion and epidural hemorrhage due to a fall on the stairs, S06, were common. Lastly, in W13, 91% of cases occurred in people in their 40s to 70s due to falls from buildings or structures, confirming that they occur frequently in middle-aged people, Z47 had the most frequent orthopedic follow-up treatment, and S72 had a fracture of the femur. It was found to be the second most common. In this way, the frequency of falling patients was analyzed, and the age and main diagnosis code at which most falls occurred were analyzed.

Objectives : This study was undertaken to identify the clinical and psychological characteristics in patients of mental disability assessment following traumatic brain injury who had the finding with or without abnormal brain imaging study. Methods : A consecutive series of 59 patients were assessed in hospital from January 1994 to December 1998. Patients were divided into 2 groups based on normal or abnormal brain imaging and the two groups were compared in demographic characteristics, psychiatric symptoms, type of head injury, clinical psychological findings. There were 27 patients with abnormal findings and 32 with normal findings in brain imaging study. Results : Abnormal finding group in brain imaging study had significantly higher incidence of psychosis, decreased memory, decreased appetite, increased nihilistic idea, and intracranial hemorrhage. Also, abnormal finding group showed significantly lower level of performance on the block design subtest of K-WAIS and had significantly lower scores on F, hypochodriasis, depression, hysteria, psychopathic deviate, psychasthenia and schizophrenia subscale of the MMPI. Conclusion : The findings suggest that the patients undergone brain surgery due to intracranial hemorrage at that time of brain injury may have higher frequency of abnormal findings in brain imaging study, complain more cognitive and affective symptoms, and have lower the abstract concept formation and perceptual organization abilities.

Purpose : To promote awareness and efforts by pediatricians to identity and prevent child abuse by investigation of characteristics of victim and types of injury caused by abuse. Methods : A retrospective study was performed with 20 patients who had been diagnosed or suspected as child abuse at Hallym University Hospital from January 1999 to December 2005. The medical records, radiologic documents, and social worker's notes were reviewed to investigate age, sex, visiting time, form of abuse, perpetrator, risk factor, and type of injury. Results : The mean age of the subjects was 2.8 years. Fourteen patients were between 0-1 years old, 2 patients between 1-6 years old, 3 patients between 7-12 years old, and 1 case over 13 years old. The ratio of male to female was 1:1. The majority of these patients (70%) visited via emergency department. Eight five percent of these patients reported with physical abuse, 5% psychological abuse, 5% sexual abuse, and 5% neglect respectively. The suspected perpetrator was the biological father in six cases, the biological mother in three cases, the stepmother in two cases, caregiver in one case, relatives in one case and "unknown" in six cases. Bruise and hematoma (80%) were the most common physical findings. Skull fractures were diagnosed in six cases, long bone fractures in two cases, hemoperitoneum in two cases, subdural hemorrhage in 10 cases, epidural hemorrhages in two cases, subarachnoidal hemorrhages in two cases, and retinal hemorrhages in five cases respectively. Seventeen cases required hospitalization and surgical operations performed were in nine cases. Four patients died and three patients had sequalae such as developmental delay and quadriplegia. Conclusion : Child abuse results in high mortality and morbidity in victims. Therefore early recognition and prevention is very important. Pediatricians should always suspect the possibilities of abuse in cases of fracture, intracranial hemorrhage, abdominal injury, or even any injury to the body. We recommend that the clinical investigation of suspicious children should include a full multidisciplinary social assessment, a skeletal survey and CT or MRI.

Multlvalvular heart surgery was performed In 78 cases, in the Department of Thoracic & Cardiovascu far Surgery of Chonbuk national University Hospital from november 1983 to March 1994. There Where 31 men and 47 women. whose ranged from 14 to 63 years. The causes of the valvular lesions were 57 rheumatic origin, 18 degenerative, 1 previous endocarditls, 1 prosthetic valve mal-function. There were 25 double valve replacement with or wit out tricuspid valve repair, i M VR and aortic valve repair, 18 MVR and tricuspid valve repair, 1 MVR and aortic and tricuspid valve repair, 10 AVR and mi- tral valve repair, 1 AVR and tricuspid valve repair, 8 mitral aortic valve repair, 13 mitral and tricuspid valve repair. They were improved mean New York Heart Association functional cldss, from 2.72% 121 Early deaths were 5 cases(6.4%). The cause of death wet'e low cArdiac output syndrome. veritricular tachycardia, massive bleeding and cerebral thromboembolism. All the survivors belonged to New York Heart Association functional class I or ll at discharge. The patients who had had valve replacement operation were medicated with warfarin to maintain the level of 30∼ 50% of normal prothrombin time. During follow-up(93.6%, mean 49.9 months), 2 late deaths were developed. One was due to intracranial hemorrhage and the other congestive heart failure. The pre-operative New York Heart Association Functional class IV was statistically sig ificant operat- ive risk factors(p< 0.05).

Purpose : There is growing use of continuous renal replacement therapy(CRRT) for pediatric patients, but reports about the use and outcome of CRRT in children is rare in Korea. We report our experiences of CRRT in critically ill pediatric patients. Methods : We reviewed the medical records of 23 pediatric patients who underwent CRRT at Asan Medical Center between May 2001 and May 2004. We evaluated underlying diseases, clinical features, treatment courses, CRRT modalities and outcomes. Results : Ages ranged from three days to 16 years with a median of five years. Patients weighed 2.4 to 63.9 kg(median 23.0 kg; 10 patients ${\leq}20kg$). The underlying diseases were malignancy(nine cases), multiple organ dysfunction syndrome(five cases), hyperammonemia(four cases), acute renal failure associated with liver failure(three cases), dilated cardiomyopathy(one case) and congenital nephrotic syndrome(one case). Pediatric Risk of Mortality(PRISM) III score was $17.6{\pm}7.6$ and the mean number of failing organs was $3.0{\pm}1.7$. Duration of CRRT was one to 27 days(median : nine days). Eleven patients(47.8%) survived. Chronic renal failure developed in two cases, intracranial hemorrhage in one case, and chylothorax in one case among the survivors. PRISM III score and the number of vasopressor before the start of CRRT was significantly lower in the survivors($12.7{\pm}4.2$ and $0.9{\pm}1.1$) compared with nonsurvivors($22.1{\pm}7.8$ and $2.4{\pm}1.4$)(P<0.05). Conclusion : CRRT driven in venovenous mode is an effective and safe method of renal support for critically-ill infants and children to control fluid balance and metabolic derangement. Survival is affected by PRISM III score and the number of vasopressors at the initiation of CRRT.

This is a report on the clinical outcome and hemodynamic profile of the ATSwcardiac valve prosthesis, which is a recently introduced pyrolytic carbon bileaflet prosthesis. We retrospectively reviewed the early outcome of 100 consecutive patients who underwent isolated cardiac valve replacement with the ATS(w prosthesis from October 1994 through June 1996 at our hospital. All patients were evaluated with Doppler echocardiography before discharge from the hospital. The mean age of the patients was 48.6 years(range: 2 to 74). A tota of 124 prosthesis were implanted; 71 mitral, 46 aortic, and 7 tricuspid. The two most frequently used sizes were 27 mm(40.8%) and 29 mm(35.2%) in the mitral position, and 23 mm(30.4%) and 21 mm(28.3%) in the aortic position. There was no early or late death. The total follow-up period was 950 patient-months with 99% follow-up rate. Serious late morbidity occurred in three patients; reoperation in two patients for late rupture of Sinus of Valsava in one and for endocarditis with prosthetic dehiscence in the other, and intracranial hemorrhage due to hypertension in one patient. There has been no thromboembolic complication or structural valval deterioration. In the mitral position, the average values of peak and mean transprosthetic pressure gradients and valve area calculated from pressure half time were 6.9$\pm$2.8 mmHg, 2.6$\pm$ 1.5 mmHg, and 2.7 $\pm$0.8 cm2 respectively. In the aortic position, the peak and mean pressure gradients'were 26.4 $\pm$ 15.9 mmHg and 14.2 $\pm$ 7.9 mmHg. For the mitra prostheses larger than 25-mm size, there was no significant difference among prosthetic sizes in terms of transprosthetic gradients, whereas there was a significant negative correlation between the prosthesis size and the transprosthetic gradients for the aortic valves. The peak and mean Pressere pradients were 52.2 $\pm$ 17.6 tmHg and 26.9$\pm$ 7.4 mmHg across the 19-mm aortic Prostheses, and 27.1 $\pm$ 11.9 mmHg and 13.3$\pm$6.6 mmHg across the 21-mm size. Above results can lead to the conclusion that the early clinical outcome of the ATS valve prosthesis is quite satisfactory, And the hemodynamic characteristics are comparable, if not better, with other bileaflet prostheses.

Background: The aortic arch replacement in an acute aortic dissection is technically demanding procedure that has a lot of postoperative morbidity and high mortality The authors have applied several techniques of aortic arch replacement to overcome the risks of the procedure. Therefore we analysed the results of these techniques. Material and Method: From March of 1996 to July of 2002, we performed 31 cases of the aortic arch replacement in the Stanford type A acute aortic dissection. There were 12 male and 19 female patient's with 59.6$\pm$9.4 years of mean age. Among them 18 cases were treated with the hemiarch replacement and 13 cases with the total arch replacement. We approached the aortic arch through median sternotomy in all but 3 cases of Clamshell incision and applied the deep hypothermic circulatory arrest with retrograde cerebral perfusion. The associated procedures were 2 Bentall's procedures, an axillobifemoral bypass, a femorofemoral bypass and a carotid artery bypass. Result: The postoperative morbidities were 8 acute renal failures, 3 CNS complications, 2 low cardiac output syndromes, 2 malpefusion syndromes, and 2 deep wound infections. There were 4 cases of early hospital mortality which were from an acute renal failure a postoperative bleeding, a low cardiac output syndrome, and a reperfusion syndrome. There were 3 cases of late hospital mortality which were from an acute renal failure, and 2 multiorgan failures. So the total mortality rate was 22.5%. There were 4 cases of late mortality after the discharge, which were form 2 cases of distal anastomotic rupture and 2 cases of intracranial hemorrhage. Conclusion: The hemiarch replacement has relatively shorter operative time and lower hospital mortality but higher late mortality than the total arch replacement. The total arch replacement needs more technically demanding procedure.
