1. Fifty one cases of fractures of the shaft of the femur in children, treated at Seoul National University Hospital during the seven years, from August 1962 to July 1969, were analyzed. 2. In thirty eight of the cases fracture involved the middle third of the shaft, in eleven the upper third, and in two the lower third. 3. Bryant traction was employed in fifteen of the cases ranging from four months to six years of age. One case, five years old, was complicated by Volkmanns ischemic contracture on both legs. 4. Russell traction was employed in eleven of the cases ranging from six to fourteen years of age. Angulation and distraction must be watched especially in the younger age group, although we encountered no serious complications which required subsequent treatment. 5. Hoke traction was employed in twelve of the cases ranging from six to eleven years of age. Although this form of treatment is not particularly popular, we are of the opinion that it is the treatment of choice over two years of age and,under six years of age and that between six and twelve years of age it may be optionally employed along with Russell traction. We found it. particularly useful and convenient in selected cases in which Russell traction could not be effectively employed. 6. In some of the complicated cases, open reduction and internal fixation, closed reduction with pin and plaster immobilization, or skeletal traction was employed.

This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

Since Palmer's introduction of the torn medial collateral ligament, many clinical and anatomical studies were performed. But any reconstructive procedure of the medial collateral ligament of the knee known to us, has not solved the problem completely yet. The purpose of present study is to describe a technique of reconstruction, socalled Tatsuzawa's tenodesis surgery of transposed semitendinosus tendon, and is to report the clinical results of 45 cases treated by his procedure between April 1976 and June 1981. In addition, significance of the procerdure was compared with the result of primary closure group of the torn ligament. Tatsuzawa's procedure consists of reinforcement surgery of the repaired or unrepaired torn medial collateral ligament with forwardly transposed semitendinosus. The semitendinosus tendon was brought forward to lie adjacent to deep layer of the medial collateral ligament. The transposed part of the tendon was sutured throughout its length to the medial collateral ligament and to the medial aspect of the tibia and femoral condyle. Because the direction of transposed tendon as similar to the direction of fibers of medial collateral ligament, the procedure was very simple and anatomical one, and had some functional advantages. In this series some old cases are treated only with tendon reinforcement operation without repairing the laxed torn ligament. The results of the surgery were evaluated by the Asais modification of the Feltons evaluation criteria. Results obtained were as follows: 1. In semitendinosus tenodesis with or without primary repair of the torn ligament, satisfactory results were obtained (excellent and good) in 33 cases (73.3%). But in 20 cases of the primary repair group, the satisfactory results were obtained in 11 cases (55%). More satisfactory results were obtained with the semitendinosus tendon reinforcement operation of the torn ligament than only with primary repair. 2. In 29 cases with fresh injury of the medial collateral ligament in which the primary repair together with the tendon reinforcement procedure was performed, satisfactory (excellent and good) results were obtained in 72.4% (21 cases), and in 16 untreated old cases in which only the tendon reinforcement procedure were done, satisfactory results were obtained in 75%. 3. In 5 cases having medial collateral and anterior cruciate ligaments tear, excellent results were obtained in 3. This explains that semitendinosus tendon reinforcement procedure is the key one of the reconstructive operative procedures. It is thought that the procedure is also effective for the anterior cruciate tear to provide the anterior instability.

This study observed the changes of the glycogen content in extensor digitorum and soleus by electrical stimulation on the sciatic nerve with various frequencies, and the result were compared with those of treadmill running exercise. The results are summarized as follows ; The glycogen content of extensor digitorum longus was greater than that of the soleus in the normal group, and the reducing amount of glycogen content of extensor digitorum longus was greater than that of the soleus by overnight fasting. As the frepuency of electrical stimulation was increased by 2, 5 and 10Hz., the glycogen content of the extensor digitorum longus was slightly reduced or changed minimally. As the loading period of clectrical stimulation was increased to 30 and 90minutes, the glycogen content of extensor digitorum longus was much reduced from early stage, and that of the soleus was the same tendency as the frepuency increased. The glycogen content of the extensor digitorum longus was proportionally reduced by treadmill running excercise, and that of the soleus was much reduced from the early stage. In summary, based on the experimental evidence of this investigation, it showed the different physio-chemical responses of th fast and slow twitch muscle fibers by electrical stimulation, and also not the equal responses of muscle fibers by electrical stimulation and treadmill running exercise.

It is often difficult, on the basis of clinical examination and conventional investigations, to evaluate the functional impairment of brain in children with cerebral palsy in which early detection remains a challenge. This study was designed to know the usefulness of single photon emission tomography(SPECT) of the brain with technetium-99 m hexamethylpropyleneamineoxime (99mTc-HMPAO) as a semiquantitative method of determination of right-left asymmetries in tracer uptake and a change in antero-posterior regional cerebral blood flow(rCBF) distribution. We investigated 33 children with cerebral palsy aged from 4 months to 48 months(mean 19.3 months). The results were as follows: right to left ratio and regional index of a transverse view were useful to quantify the decrease of tracer uptake in left hemiplegia, but not in right hemiplegia who were all mild in severity, and in tetra- and diplegia in which cerebral lesions were found bilaterally; cortico-cerebellar ratios of a sagittal view were found useful to detect a decrease of rCBF distribution in tetra- and diplegia ,which was not distinct by means of right to left ratio and regional index on transverse view. The results suggest that semiquantitative analysis of 99mTc-HMPAO Brain SPECT would be a valuable complementary tool for determination of topographical involvement in cerebral palsy.

PURPOSE: IgA nephropathy (IgAN) is one of the major causes of end-stage renal disease. Mass school urine screening (SUS) has been performed to enable early detection of chronic renal diseases, including IgAN. We wanted to evaluate the patients with IgAN, including those diagnosed through SUS. METHODS: Between 1998 and 2010, 64 children were diagnosed with IgAN based on renal biopsy results obtained at the Pediatric Nephrology Department, OO University Hospital. We divided these patients into the SUS group (37 cases), diagnosed through SUS, and the symptomatic (Sx) group (27 cases), diagnosed clinically. The medical records of both groups were analyzed retrospectively. RESULTS: The mean age of the SUS and Sx groups was 10.8+/-2.7 and 9.5+/-3.4 years (P>0.05), respectively. Both groups had a higher proportion of male patients. The time from the notification of an abnormal urinary finding to a hospital visit or renal biopsy was shorter in the Sx group than in the SUS group. Regarding clinical manifestations, there were fewer cases with gross hematuria (P<0.001) and edema (P=0.008) in the SUS group, but there were no differences in terms of the therapeutic regimen and treatment duration. Regarding laboratory parameters, the Sx group had a higher white blood cell count (P=0.007) and lower hemoglobin (P=0.007) and albumin (P=0.000) levels. There were no differences in the renal biopsy findings in both groups, based on the history of gross hematuria or the severity of proteinuria. However, in all 64 patients with IgAN, the light microscopy findings (Hass classification) were related to a history of gross hematuria or the severity of proteinuria. CONCLUSION: There were no significant clinical and histological differences between the groups, as both had early stage IgAN. Although SUS facilitates the early detection of IgAN, long-term, large-scale prospective controlled studies are needed to assess the benefits of early diagnosis and treatment in chronic renal disease progression.

BACKGROUND: Lidocaine is often administered intravenously to suppress airway reflexes associated with tracheal intubation or tracheal suction. In addition, lidocaine is known to have airway relaxant effects through a direct relaxant mechanism on the smooth muscle. The presence of airway epithelium has been reported to reduce the sensitivity and maximum contractile response to histamine or acetylcholine(ACh). The purpose of this study was to determine whether the cumulative application of lidocaine may cause a concentration-dependent relaxation of the rat tracheal smooth muscle strips with intact or rubbed epithelium. METHODS: Using the rat tracheal smooth muscle strips, the effects of 10 6~3 10 3M of lidocaine pretreatment on isometric tension induced by 40 mM of K+ or 10 5M of ACh in presence or absence of adherent epithelium, and the influences of 10 6M of propranolol, 10 4M of L-NAME and 10 6M of atropine on relaxing response of lidocaine were studied. RESULTS: The tracheal smooth muscle concentration induced by K+ and ACh was similar magnitude both in presence or absence of adherent epithelium. The removal of epithelium did not affect the relaxant effect of lidocaine on the K+ and ACh-induced tracheal smooth muscle contraction. Lidocaine pretreatment reduced Ca2+-dependent contraction of the rat tracheal smooth muscle. Following pretreatment of the tracheal smooth muscle preparations respectively with propranolol, L-NAME and atropine the relaxing responses to lidocaine of tracheal smooth muscle were not depressed. CONCLUSIONS: These results suggest that the effect of the epithelium on lidocaine-induced relaxation of the tracheal smooth muscle is not significant and lidocaine may directly relax tracheal smooth muscle by the influences on the Ca2+ mobilization.

BACKGROUNDS/AIMS: Traumatic pancreatic injury is rare and various surgical procedures can be applied according to the severity of injury. We reviewed our experience of pancreatic injury and investigated the clinical outcome. METHODS: Fifty-six patients were treated conservatively or with surgery for pancreatic injury at the Department of Surgery, Korea University Medical Center of Korea University College of Medicine from January 2001 to February 2012. RESULTS: Forty-one men and 15 women were included (mean age, 32 years; range, 5-66 years). Twelve patients were hypotensive at admission. According to the American Association for the Surgery of Trauma grade, 15 patients were grade I, 16 were grade II, 10 were grade III, 13 were grade IV, and one patient was grade V. A total of 41 patients underwent exploratory surgery. Complications developed in 35 patients, and 19 patients demonstrated intra-abdominal abscesses associated with pancreatic leakage. Four mortalities occurred. More adult patients (n=42) required intensive care than that of pediatric patients (n=14) (p=0.03). However, more pediatric patients had hyperamylasemia at admission (p=0.023). A significantly higher proportion of patients in the hypotensive group had blunt abdominal injuries, associated extra-abdominal injuries, combined intra-abdominal injuries, longer ICU stays, and a higher mortality rate. CONCLUSIONS: Associated intra-abdominal and extra-abdominal injuries are frequent in patients with traumatic pancreatic injury. Despite the complication rate, most patients recovered. Mortalities were associated with combined injuries being placed into bleeding, hypovolemic shock, and multiorgan failure.

Hypertrophic cardiomyopathy(HCM) in the infant of diabetic mother is transient, nonfamilial condition with morphologic and functional abnormalities that resemble familial HCM. However, unlike ""true"" HCM, the cardiomyopathy of infants of diabetic mothers is usually innocent and transient, resolving during the first 6 months of life. Cardiorespiratory distress may improve within 2 to 4 weeks. Reported are two cases of infants with hypertrophic cardiomyopathy, attributed to maternal diabetes. These infants developed respiratory distress within a few hours after birth, but needed only supportive care. Echocardiogram showed myocardial hypertrophy regressing over two to four months.
