It is often difficult to achieve bony union and eradicate infection in treating infected non-unions of the fractured long bones. Authors carried out a clinical analysis of the 35 infected non-union cases, all aged 21 years or older, treated and followed for 6 months to 6 years from July 1979 to July 1988 in order to determine the possible factors which might influence the time required for attaining union. The results were as follows: l. In 22 of the 35 infected non-unions, the primary fracture site was open (62.9%). The remaining 13 cases (37.1% ) were the closed fractures associated with postoperative infection. 2. The sites of infected non-union were tibia in 19 (54.3%), femur in 13 (37.1%), and upper extremity in 3 (8.6%) cases. Tibia was more often involved in open fractures (63.6%). Femur, on the other hand, was more involved in closed fractures (61.5%). 3. After an average of 3.3 times of bony procedures, primary fixation was left in place in 15 (42.9%), external fixation was required in 11 (31.4%), and internal fixation was performed in 9 (25.7%). Bone graft was performed in 26 cases (74.3%). 4. Time required for achieving union was 7.1 month with stable primary fixation and 21.7 months with unstable primary fixation. Femur and tibia united at 10.5 (mean; ranged from 4 to 29) and 7.0 (mean; ranged from 3 to 19) months, respectively. 5. Bony union was delayed as the number of prior surgical procedures before successful treatment increased; the time for union was significantly shorter when either stable primary fixation or external fixation was combined with bone grafting. 6. Firmer bony union was achieved after performing Osteoperiosteal decortication with autogenous cancellous bone graft even in the presence of remaining infection at the non-union site.

PURPOSE: We compared the first postoperative diagnostic and post-therapy scans of patients who received therapeutic doses of I-131, to investigate the difference in clinical outcomes between patients with concordant findings of diagnostic and post-therapy scans and patients with discrepant (more lesions in post-therapy scan) findings. MATERIALS AND METHODS: The first postoperative diagnostic and post-therapy radioiodine scans of one hundred forty three patients with well differentiated thyroid carcinoma were reviewed. Diagnostic scans were obtained following ingestion of 185 MBq of I-131 and post-therapy scans were obtained after therapeutic dose of 3.7~9.3 GBq of I-131. Successful ablation was defined as no radioiodine uptake on diagnostic radioiodine scan and normal range of serum thyroglobulin level (<10 ng/ml) during serum TSH elevation. RESULTS: Discrepant scan findings were noted in 25 (17.5%) patients. Twenty-two patients (15.4%) showed more lesions in post-therapy scan and 3 patients (2.1%) showed stunning effect. Nine (64.3%) of 14 patients with distant metastasis revealed metastatic lesion(s) only on post-therapy scan. Stunning effect was considered as sublethal damage in 1 patient and treatment by a diagnostic dose in 2 patients. Ablation was achieved in 52.4% (75/143) of all patients. Ablation rate and mean cumulative radioiodine dose were not different statistically between concordant and discrepant groups. CONCLUSION: There were 17.5% difference between diagnostic and post-therapy scan findings when using 185 MBq of I-131 as a diagnostic dose. However, 64.3% of distant metastases were revealed only on post-therapy scan. Ablation rate and mean cumulative radioiodine dose were not different statistically between concordant and discrepant groups. The stunning effect was considered as not only sublethal damage but also treatment by a small diagnostic dose of radioiodine.

Chronic intestional pseudoobstruction syndrome is a rare clinical condition in which impaired intestinal peristalsis. Causes recurrent symptoms of bowel obstruction in the absence of a mechanical occlusion. This syndrome may involve variable segments of small or large bowel. And may be associated with urinary bladder retention. This study included 6 children(3 boys and 3 girls) of chronic intestinal obstruction. Four were symptomatic at birth and two were of the ages of one month and one year. All had abdominal distention and defication difficulty. Five had urinary bladder distention. Despite parenteral nutrition and surgical intervention(ileostomy or colostomy), bowel obstruction persisted and four patients expired from sepsis within one year. All had gaseous distention of small and large bowel on abdominal films. In small bowel series. Consistent findings were variable degree of dilatation. Decreased peristalsis(prolonged transit time) and microcolon or microrectum. This disease entity must be differentiated from congenital megacolon, ileal atresia and megacystis syndrome.

PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

Removal of blunt esophageal foreign bodies using Foley catheter under a fluoroscopic guidance is a well-recognized procedure. However, since this procedure is rather cumbersome and uncomfortable to the patient, the authors tried to find an easier and more convenient modified technique. For 10 patients with esophageal foreign body, we tried the method to the patients who is lying in the right lateral decubitus position and 3 assistants hold head. arms, trunk and legs of the patients without tilting the table and without using immobilizer. Foley catheter is inserted through nostril, nasal cavity and pharynx to esophagus. In order to identify the Foley catheter in esophagus, 0.025 inch short wire was inserted in the Foley catheter. The balloon of a Foley catheter was inflated by 10cc of air, and the syringe was kept attached to the Foley catheter during the procedure. After passage of the foreign body through the upper esophageal sphincter, the balloon was deflated immediately and the foreign body was removed through the mouth. We successfully removed in removing all the blunt esophageal foreign body with ease. This modified method is also fast, safe and efficient.

8.Nodular Fasciitis Mimicking Malignant Tumor on 18F-FDG PET/CT.
Korean Journal of Nuclear Medicine 2005;39(4):263-265
A 26 years old male patient with Hodgkin's disease, considered as complete remission, underwent 18F-FDG whole body PET/CT. 18F-FDG whole body PET/CT showed unexpected hypermetabolic nodule in left quadratus femoris muscle suggesting local recurrence. Subsequent MRI also revealed well-enhancing nodular lesion with intermediate and high signal intensity on T1WI and T2WI, respectively. The lesion was confirmed as nodular fasciitis by pathologic examination of the excised specimen.

9.Incidental Multiple Pulmonary Nodules: Benign Metastasizing Leiomyoma and 18F-FDG PET/CT.
Nuclear Medicine and Molecular Imaging 2007;41(3):258-259
Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

Journal of the Korean Radiological Society 1983;19(1):78-87
Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult tointerpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases ofhistologically confirmed primary lung cancer from Jan. 1974 to April 1982 at Seoul National University. The resulsare as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex ratio was 3.8:1 andthere was no sex difference in Adenocarcinoma. 2. Distrubution of histologic types of primary lung cancer asfollows; Squamous cell Carcinoma 50.6%, Small Cell Carcinoma 22.5% lange Cell Carcinoma 9.3% Bronchegenic adenocaranoma 10.5% Bronchioloalveolar Cell Carcinoma 1.9%. Adenosquamos Carcinoma 0,6%, Carcinoid Tumor 0.3%, AdenoidCystic Carcinoma 0.3%. 3. Radiologic findings by histologic types as follows; a) Squamous cell carcinoma commonlypresent as collapse(51.8%) peripheral mass (40.8%), pneumonitis(37.2%), hilar involvement(34.8%), and in singleabnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement(78.1%),mediastinal wideing or mass (53.4%) and in single abnormality, hilar involvement(58.3%). c) Large cell carciomacommonly present as hilar involvement(50%) pneumonia(46.7%), collapse (40%), peripheral mass(36.7%) and in singleabnormality, large peripheral mass (33.3%). d) Bronchogenic Adenocarcinoma commonly present as peripheralmass(44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass(50%). e)Solitary peripheral mass commonly present as lobulation(48%) and spiculated margin (51%), but no specific findingsby histologic types. Cavitary formation was most common in Squamous cell carcinoma.
