OBJECTIVE: To verify proper stimulation point of ulnar nerve at the wrist by investigating anatomical relation of ulnar nerve and flexor carpi ulnaris (FCU) muscle. METHOD: Cadaver dissection of 9 wrists was done to identify gross anatomical relation of ulnar nerve and FCU muscle. Ultrasonography of 17 healthy volunteers was done for the measurement of distance from lateral border of FCU muscle to ulnar nerve at three sites. Ratios of these distances to total width of FCU muscle and FCU tendon were calculated. RESULTS: FCU muscle was composed of lateral tendinous and medial muscular portion, and all ulnar nerves were located under the tendinous portion of FCU muscle on cadaver dissection. Ultrasonographic distances from lateral border of FCU muscle to ulnar nerve were 4.6+/-3.3 mm, 4.8+/-4.0 mm and 5.9+/-3.1 mm from distal to proximal sites. The ratios to total width of FCU muscle were 31.02+/- 23.31%, 24.30+/-26.12% and 24.48+/-13.01%, which showed that the ulnar nerve was closer to the lateral border than the medial border. The ratios to total width of FCU tendon were 49.63+/-41.35%, 51.30+/-50.46% and 64.59+/-36.79%, which showed progressive increment from distal to proximal sites. CONCLUSION: Proper stimulation point of ulnar nerve at the wrist is the lateral border of FCU muscle than the medial border. However, the proximity of ulnar nerve to the medial or lateral border was not conclusive, because the ratio to FCU tendon was not consistent in three sites of the wrist. Further electrophysiologic study is necessary for the comparison of proper stimulation point based on FCU tendon.

Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia.

Epidural abscess and vertebral osteomyelitis induced by epidural injection is rare but one of the most serious complications. A 58-year old woman complained of aggrevating radicular pain to bilteral lower legs, tenderness on coccygeal area and claudication, after epidural injection for management of intractable sciatica. MRI and ultrasound revealed epidural abscess compressing dural sac at the level of L5-S1 vertebral body, sacrococcygeal abscess, and later S5- 1stcoccyx osteomyelitis. We report epidural abscess and vertebral osteomyelitis induced by caudal epidural injection.

Hemiplegic patients with an ankle foot orthosis (AFO) has a tendency to show external rotation of affected side foot. External rotation inhibiting shoes (ERIS) were designed to inhibit excessive rotation of hemiplegic foot. ERIS were applied to two hemiplegic patients who were able to walk independently with a plastic AFO. Both of them showed an excessive external rotation of hemiplegic foot after AFO apply. Each patient tried to walk with a pair of common shoes first and ERIS later. The external rotation angle, step length, stride length, cadence, speed were measured by footprint method. The external rotation angle of hemiplegic foot was significantly decreased with ERIS than with common shoes. However they did not show consistent improvement in the step length, stride length, cadence and speed. We reported that hemiplegic patients who walked with ERIS showed remarkable reduction in excessive external rotation of hemiplegic foot.

OBJECTIVE: We investigated the usefulness of the scintigraphic swallowing study in selecting the patients with low risk of aspiration pneumonia among those who showed small amount of laryngeal aspiration in videofluoroscopy. METHOD: Scintigraphic swallowing study was performed in 22 patients with brain injury who showed small amount of laryngeal aspiration in videofluoroscopy. Oral feeding was tried in the patients who showed airway clearing function or no aspiration in scintigraphic swallowing study, and they were followed up for possible aspiration pneumonia. RESULTS: Total of sixteen patients showed no aspiration in scintigraphic swallowing study. Five patients showed laryngeal aspiration, but preserved airway clearing function. One patient showed impairment of airway clearing function. Oral feeding was tried in 21 patients. Oral feeding was successful in 18 of 21 patients but not in 3 patients because of dysphagia or cough. Only 1 patient developed pneumonia after 246 days of follow up. CONCLUSION: Scintigraphic swallowing study is useful to select the patients with low risk of aspiration pneumonia among the patients who showed small amount of laryngeal aspiration in videofluoroscopy.

Central pontine myelinolysis is a demyelinating disease of central pons. Nocturnal polyuria is defined as increased urination during nighttime with a nocturnal fraction exceeding from 20% to 33%. We have experienced nocturnal polyuria developed in two patients with central pontine myelinolysis. In these cases, serum antidiuretic hormone and urine osmolality were lower at nighttime than daytime. It suggests that nocturnal polyuria is caused by abnormal diurnal variation of antidiuretic hormone. In the first case, nocturnal polyuria was recovered spontaneously and also follow up brain MRI showed decreased signal intensity in pons. In the second case, nocturnal polyuria was improved after the treatment of intranasal desmopressin. It appeares that central pontine myelinolysis can cause nocturnal polyuria due to the interruption of antidiuretic hormone pathway. The symptom of nocturnal polyuria can be treated by desmopressin.

This report present the result of the national survey of pediatric surgeons' preferences on diagnosis and treatment of Hirschsprung's disease(HD) carried out in 1993. The questionnaires were sent to twenty-seven members of the Korean Association of Pediatric Surgeons (KAPS) working in twenty-four institutions. The questionnaires were designed to determine the individual surgeon's preference for the methods of diagnosis and treatment of the disease. Twenty-three pediatric surgeons from twenty institutions returned completed forms. The total number of patients diagnosed with HD in 1992 was 190 in this group. The estimated incidence of HD was 1/3,900. The most important symptom was delayed meconium passing and the most preferred diagnostic procedure was barium study. Anorectal manometric examination was carried out by 13 pediatric surgeons and 19 confirmed the diagnosis before operation by rectal biopsy, 12 with full-thickness biopsy and 7 with suction. Frozen section biopsy during operation was done by 22 surgeons. Eight surgeons did one stage operation if the age of the patient is suitable. Definitive operation was usually done at the age of 6 to 11 months. The most preferred operation was Duhamel procedure done by 19. Enterocolitis was the most serious complication of HD. Most of patients had normal continence within 6 to 12 months after operation. The follow-up period was less than 6 years in 16 surgeons. The results were presented at the 9th annual meeting of KAPS in June of 1993. This is the first national survey of HD and it can provide guidelines of diagnosis and treatment of Hirschprung's disease even though it is not a detailed study of patient data.

To understand the current status of neonatal surgery in Korea, a suvey was made among the 27 members of Korean Association of Pediatric Surgeons. Response rate among surgeons was 78 perecnt, eighteen hospitals participated in this study. Five hundred and three cases of neonatal surgical patients were analyzed. In Korea, about 50% of cases were treated at the hospital in the capital city area. Regional number of patients were closely related to the regional population. Imperforate anus(19%), atresia/stenosis of gut(12%), and Hirschsprung's diseases(12%) were sitting at the top in the list. Majority of operation was done within the first week of life, especially during the first 24 hour period. Eighty per cent was major or so called index cases. Mortality in so-called index cases was 17%. High mortality was observed in patients with diaphragmatic hernia(47%), gastrointestinal perforation(65%) and esophageal atresia(28%). Low birth weight babies showed higher mortality in gastro -intestinal perforation, esophageal atresia and abdominal wall defect. These were compared to 1993 survey of Japanese Society of Pediatric Surgeons.

The first national survey on esophageal atresia and tracheoesophageal fistula was conducted to access the current status of its incidence. clinical manifestation, preoperative diagnosis and management, type of its anomaly, associated anomalies, and surgical results and course. The 43 members of the Korea Association of Pediatric Surgeons received questionnaires and registration forms to be filled out on each patient who were born during the three years from January I, 1992 through Decestricurember 31, 1994. Questionnaires composed of six broad areas which include 1) preoperative diagnosis and management, 2) surgical technic, 3) long gap, 4) postoperative management, and 5) complications and courses. A total of 148 cases was returned by 28 members working at 23 institutions and 27 members returped questionnaires. We obtained the following results by analysis of the 148 cases of tracheoesophageal anomalies. The incidence of tracheoesophageal anomaly was about 1/10,000-11,000 in 1994, which is one third of that of anorectal malformations in Korea and the distribution of the patients was almost proportionate to the size of each province. Both sexes are about equally affected. Majority of the members make diagnosis of tracheoesophageal anomaly by taking a simple infantogram with a radiopaque tube in upper pouch and a little under half(46%) prefers to perform echocardiography as a part of preoperative management to identify congenital heart disease and lateralize the aorta. Esophageal atresia with distal TEF(87.50/0) was by far the most common and threre were pure esopahgeal atresia(5.6%), H-type TEF(2.l%), and so on. About half(49%) of the patients had one or more associated anomalies in addition to tracheoesophageal anomalies. Congenital heart disease was associated in 46 cases(31 %), anorectral malfomations in 19 cases(13%), musculoskeletal anomalies in 15 cases(10%), genitourinary anomalies in 10 cases(7%) and gastrointestinal anomalies in 7 cases(5%). Postoperatively, parenteral nutrition and assisted ventilation were given in 66% and 52% of patients respectively. Ninety three(74%) of 126 cases who underwent surgical procedure, experienced one or more complications such as respiratory complication (65%), leak(22%), stricture(21%) and so on. The survival rates related to the Waterston risk categories were 90.2% in grpup A, 71.4-75% in B₁, B₂, and C groups, and 28% in group C₂ and the overall survival rate was 71.4%. Thirty six(28.6%) of 126 cases died of pneumonia/sepsis(12 cases), respiratory failure(l2 cases), and congenital heart disease(4 cases). With short term follow-up, 69% of patients have been excellent whereas remainders of the cases have suffered from some sort of morbidity related to gastroesophageal reflux, recurrent respiratory infection, and esophageal stricure.

The survey on branchial anomalies was conducted by Korean Association of Pediatric Surgeons. A total of 173 cases were reported, which were managed by 36 members and cooperators during the three years from January 1, 1993 through December 31, 1995. The following results were obtained by retrospective analysis of the 173 cases of branchial anomalies. The presenting symptoms were cervical mass in 101 cases, pit with or without discharge in 71, cervical abscess in 47 and respiratory difficulty in 3. The average age of the patients with cervical abscess was 52 months. Seventy(79%) of 89 patients with branchial anomalies and a cystic mass had their first clinical manifestations by 1 year of age, while 40(51%) of 78 patients with only a branchial cyst had their first clinical manifestation in first year of life. Radiologic studies were carried out in 77 patients(43%). The preferred diagnostic modalities were ultrasonography(47 patients), simple neck radiogram(l9) and CT scan(17). Preoperative diagnosis was correctly made in 156(91%) of 173 patients. Seventeen patients were incorrectly diagnosed as thyroglossal duct cyst in 5 patients, cystic hygroma in 4, dermoid cyst in 3, and lymphadenopathy in 3. There were no remarkable difference in sex and laterality of presentation but bilateral lesions were found in 9(5%) patients and unusual locations of the anomalies were the manubrium, left subclavicular area, median cervial area, preauricular and parotid area. There were 78(45%) patients with cyst, 52(30%) patients with sinus, 35(20%) patients with fistula and 8(5%) patient with skin tag. Embryological classification was possible in only 64(37%) patients. The 2nd branchial anomaly was present in 50 (78%), the 1st branchial anomaly in 10(18%), and the 3rd or 4th branchial anomaly in 4(6%). Histopathological study of the lining epithelium(N=134) is recorded that 45% were lined with squamous epithelium, 17% with respiratory epithelium, 6% with. squamous and respiratory epithelium, 14% with inflammatory change. Lymphoid tissue was common(62%) in the wall of the lesions. Twelve(7%) of 158 patients had postoperative complications including wound complication, recurrence and facial nerve palsy.
