Purpose: In this study, we tried to evaluate the clinical characteristics or circumstances that lead to unintentionally the delay in the diagnosis of intussusception or to the wrong direction that prevent the proper management early. Methods: All the patients of intussusception with delayed diagnosis in the department of pediatrics or emergency room at Gyeongsang National University Hospital from 1990 to 2003 were enrolled and reviewed retrospectively. Results: There were 8 boys and 6 girls and their median age was 8 months (range 2 months to 10 years). Their initial symptoms and signs were vomiting, seizure, diarrhea, lethargy, irritability, bloody stool, palpable abdominal mass, foul odor of urine and tachycardia. Clinical diagnosis or impressions at admission consisted of acute gastroenteritis, shigellosis and toxic encephalopathy, convulsive disorders, urinary tract infections, sepsis, abdominal mass and intestinal obstruction. Eight patients were luckily diagnosed due to the delayed manifestations of cyclic irritability or currant jelly stool. Six patients were not paid attentions for the possibilities of intussusception and diagnosed serendipitiously by the abdominal sonography or CT during the evaluation of the abdominal mass or distension. Only five of 14 cases (35.7%) were successfully managed by barium or air reductions. The other 9 cases needed surgical operations. Conclusion: Delayed diagnosis of intussusception arise when doctors initially diagnose the patients incorrectly due to the unusual presentations or when they overlook the newly arising symptoms or signs suggestive intussusception after the admission because they are ardently attached to the first impressions or initial clinical diagnosis.

Purpose : By comparing and analyzing treatment plans using abdominal compression and The Continuous Positive Air Pressure(CPAP) during SABR of lung cancer, we try to contribute to the improvement of radiotherapy effect. Materials & Methods : In two of the lung SABR patients(A, B patient), we developed a SABR plan using abdominal compression device(the Body Pro-Lok, BPL) and CPAP and analyze the treatment plan through homogeneity, conformity and the parameters proposed in RTOG 0813. Furthermore, for each phase, the X, Y, and Z axis movements centered on PTV are analyzed in all 4D CTs and compared by obtaining the volume and average dose of PTV and OAR. Four cone beam computed tomography(CBCT) were used to measure the directions from the center of the PTV to the intrathoracic contacts in three directions out of 0°, 90°, 180° and 270°, and compare the differences from the average distance values in each direction. Result : Both treatment plans obtained using BPL and CPAP followed recommendations from RTOG, and there was no significant difference in homogeneity and conformity. The X-axis, Y-axis, and Z-axis movements centered on PTV in patient A were 0.49 cm, 0.37 cm, 1.66 cm with BPL and 0.16 cm, 0.12 cm, and 0.19 cm with CPAP, in patient B were 0.22 cm, 0.18 cm, 1.03 cm with BPL and 0.14 cm, 0.11 cm, and 0.4 cm with CPAP. In A patient, when using CPAP compared to BPL, ITV decreased by 46.27% and left lung volume increased by 41.94%, and average dose decreased by 52.81% in the heart. In B patient, volume increased by 106.89% in the left lung and 87.32% in the right lung, with an average dose decreased by 44.30% in the stomach. The maximum difference of A patient between the straight distance value and the mean distance value in each direction was 0.05 cm in the a-direction, 0.05 cm in the b-direction, and 0.41 cm in the c-direction. In B patient, there was a difference of 0.19 cm in the d-direction, 0.49 cm in the e-direction, and 0.06 cm in the f-direction. Conclusion : We confirm that increased lung volume with CPAP can reduce doses of OAR near the target more effectively than with BPL, and also contribute more effectively to restriction of tumor movement with respiration. It is considered that radiation therapy effects can be improved through the application of various sites of CPAP and the combination with CPAP and other treatment machines.

Hepatomegaly and liver dysfunction might develop in patients with diabetes mellitus due to glycogen deposition or nonalcoholic steatohepatitis. We experienced a case of hepatic glycogenosis in a patient with type 1 diabetes mellitus who presented with recurrent hypoglycemia, suggesting impairment of glycogenolysis and gluconeogenesis. A 10-year-old girl with a 4-year history of type 1 diabetes mellitus was admitted because of recurrent hypoglycemia and abdominal pain in the right upper quadrant. She had Cushingoid features and hepatomegaly that extended 6 cm below the right costal margin. Laboratory data and radiologic examination revealed elevated liver enzyme levels due to fatty liver. Periodic acid-Schiff (PAS) staining revealed intense glycogen deposition in the cytoplasm of the hepatocytes and PAS reactivity was lost with diastase treatment. At 2 months after administration of glucagon injection and uncooked cornstarch between meals and at bedtime, the hypoglycemic episodes and liver dysfunction improved. It is important to distinguish hepatic glycogenosis from steatohepatitis, because it is possible to prevent excessive hepatic glycogen storage in hepatic glycogenosis cases by strictly controlling blood glucose level and by glucagon administration. To prevent severe hypoglycemic symptoms accompanied by hepatic glycogenosis, we suggest that uncooked cornstarch, which is effective in maintaining blood glucose level, can also be administered.

Splenic marginal zone lymphoma (SMZL) is a rare type of non-Hodgkin's lymphoma (NHL). We report here on a patient who displayed the synchronous occurrence of SMZL and early gastric cancer (EGC). The patient was a 74 year-old male with liver cirrhosis. An EGC in the gastric antrum was diagnosed and the preoperative abdomen computed tomography scan revealed splenomegaly and intra-abdominal lymphadenopathy. We performed subtotal gastrectomy and the postoperative pathologic examination revealed adenocarcinoma limited to the gastric mucosa and SMZL in the lymph nodes. The patient recovered from the surgery without complications and is now awaiting chemotherapy. SMZL has an indolent clinical course with good long-term survival and so there is the possibility of the occurrence of a second primary malignancy. Rare cases of a second primary malignancy being diagnosed along with SMZL have been described in the literature. Patients with SMZL should be carefully followed after treatment to detect the possible occurance of a second primary malignancy.

Patient's respiration can have an effect on movement of tumor range and peripheral organs. Therefore, the respiratory signal was acquired by relation between external markers and movement of patient's abdomen during radiational therapy in order to minimize the effect of respiration. Based on this technique, many studies of rational therapy to irradiate at particular part of stable respiratory signals have executed and they have been clinically applied. Nevertheless, the phase-based method is preferred to the amplitude-based method for the rational therapy related to respiration. Because stabilization of the respiratory signal are limited. In this study, a in-house respiratory signal analysis program was developed for the phase reassignment and the analysis of the irregular respiratory signals. Various irregular respiratory patterns was obtained from clinical experimental volunteers. After then, the in-house program analyzed the factors affecting to phase assignment which is directly related to irradiated sector. Subsequently, accuracy of phase assignment was improved with removement of irregular signals by self-developed algorithm. This study is considered to be useful for not only image reconstruction and elevation of irradiating accuracy through phase assignment of RPM system but also analysis of respiratory signals. Moreover, development of 4D CT image is planed with phantom researches or clinical experiments based on this program.

Intestinal atresia is a frequent cause of intestinal obstruction in the newborn. We reviewed the clinical presentation, associated anomalies, types of atresias, operative managements, and early postoperative complications in 36 cases of intestinal atresia treated at the Department of Surgery, Kyungpook National University Hospital between January 1994 and February 2003. Location of the lesion was duodenum in 17 patients, jejunum in 11 patients and ileum in 8 patients. The male to female ratio was 1:1.4 in duodenal atresia (DA), 2.7:1 in jejunal atresia (JA) and 7:1 in ileal atresia (IA). The most common type was type III (41.1 %) in DA, and type I (52.6 %) in JA and IA. The most common presenting symptoms was vomiting(88.2 %) in DA, but in jejunoileal atresia, vomiting(89.4 %) and abdominal distension(89.4 %) were the most common sign and symptom. All cases of DA were diagnosed by plain abdominal radiography. There were 6 cases of DA with congenital heart disease, 3 cases of DA with Down syndrome and 3 cases of JA with meconium peritonitis. Segmental resection was performed in 13 cases, duodenoduodenostomy in 11 cases, membrane excision in 7 cases, jejunojejunostomy in 2 cases, gastroduodenostomy in 2 cases and ileocolic anastomosis in 1 case. There were 9 postoperative complications including 3 each of anastomotic leakage, wound infection, and intestinal obstruction 3 cases. The mortality rate for DA was 11.8 %(2/17). Both deaths in DA were attributed to congenital heart disease. The mortality rate for JA was 18% (2/11). Both cases died with sepsis and short bowel syndrome.

This study is performed to evaluate the effectiveness of a weight management program for overweight and obesity office workers; comparing their changes in the anthropometry, biochemistry, nutrient intakes, and exercise performance before and after the obesity management program. This program was performed on 39 workers, who are overweight or obese, over BMI 23 for 6 months in Jeollabuk-do public institution. As the results of this study suggests, triceps thickness (TT) of male subjects was significantly decreased (P<0.05). Waist circumference (WC), and hip circumference (HC) of the total subjects were significantly decreased after the weight management program (P<0.05). The biochemical result of the Total cholesterol (TC) (P<0.05) and LDL cholesterol (LDL-C) (P<0.01) was significantly decreased in male subjects. The results of abdominal computed tomography (CT) also showed that subcutaneous fat area (SFA) of male subjects was significantly decreased after the weight management program (P<0.01). The nutrient intake's results of female subjects, who took Fe, Vit B2, and niacin, were increased significantly after the weight management program (P<0.05). The nutrition knowledge score of male subjects was significantly increased (P<0.05), and a muscular endurance of the physical test was significantly increased after the obesity management program (P<0.01). At the work place, workers need a systemic health and obesity management program to improve their work efficiency and quality of life. After this study, the program should be developed and supported continuously to maintain positive results from this study.

Because the arm can't be sutured due to fracture during a elbow CT scan, a CT scan is proceeded in a state of abdomen and L-spire are overlapped which beam hardening artifact is done many times, and it often lowers the quality of elbow CT images. So there are many difficulties in reading and due to increase in radiation dose from it, the number of patient's exposure keeps increasing. In this research, it plans to improve the quality of the images by avoiding overlap with abdomen, and increasing the number of photon overlapped with lung field which the line attenuation is relatively small. The way of experiment is based on patient's right elbow and place him as head first position, then place his elbow at L2-3 level in supine position, turn about 30 degrees to the left in non-control breathing and in supine position, and compared with full inspiration after overlapping with lung. After figuring out the average value and standard deviation data using Image J program 5 times each for 16, 128 channels, the evaluation is proceeded by measuring each of CNR, MSR are statistically analyzed using SPSS program. Therefore, through positioning and inspiration during elbow CT scan, the way of inspection minimized the exposure radiation dose, and seems to be meaningful in a way to improve the quality of the images.

Newborns with ileal atresia freqently present with abdominal distension, bilious vomiting. and failure to pass meconium. Diagnosis is usually established on plain x-ray of the abdomen by the findings of distended small bowel loops and air-fluid levels. In the period of October 1988 to February 1994, 8 patients with congenital ileal atresia were operated and the following results were obtained. 1. Eight patients were comprised of 4 males and 4 females, the ratio of male and female was 1 : 1. 2. Six patients(75%) had been admittted to our hospital during three days of life. 3. Congenital ileal atresia was in 8 cases : Type I in two(25%), Type II in two(25%), Type IIIa in three(37.5%), Type IIIb in one(12.5%). 4. There was one premature patient who was small for gestational age. 5. Overall, abdominal distension and bilious vomiting occurring in seven patients, were frequent presenting complaints. 6. Diagnosis was possible with clinical symptom and simple abdomen. 7. Operative treatment was undertaken as soon as the diagnosis was made. In seven cases a primary end-to-end anastomosis was performed after resection of dilated proximal loop. 8. A total of four associated congenital anomalies were found in one patient. 9. Postoperative complications occurred in three cases(37.5%).

We report a case of a patient with necrotizing fasciitis followed by liver abscess. A 51-year-old man was admitted to our hospital with a 5-day history of fever and chills with painful swelling of the right thigh. A magnetic resonance imaging (MRI) scan showed fluid collection with numerous dark signal intensities considered as air-bubbles between the posteromedial and posterolateral groups of the right thigh, resulting in presumptive diagnosis of necrotizing fasciitis. At the time of admission, an ultrasonograph of the abdomen showed increased parenchymal echogenicity of both kidneys and no liver abscess. Ten days after fasciotomy, an abdominal computed tomography (CT) scan showed intrahepatic abscess. Sonography-guided percutaneous drainage was performed. Both cultures of pus specimens from the liver abscess and right thigh yielded Klebsiella pneumoniae (K. pneumoniae). The patient was treated with fasciotomy several times and parenteral antibiotics, after which he began to improve. After 5 weeks, liver abscess size was reduced, and after 10 weeks, liver abscess disappeared. To the best of our knowledge, this is the first case of K. pneumoniae-necrotizing fasciitis followed by liver abscess.
