BACKGROUND: We reviewed retrospectively the clinical features and contrast material-enhanced computed tomography(CT) after blunt abdominal trauma demonstrated a characteristic hypoperfusion complex. Our purpose were to evaluate the hypothesis that children with this 'hypoperfusion complex' CT finding were associated with a tenuous hemodynamic state, severe injury and a poor outcome. METHODS: Between January 1996 and December 1999, 39 consecutive children who sustained blunt trauma and were suspected clinically of having intraabdominal injury underwent CT. Demographic data, blood pressure, indication for CT, pediatric trauma score(PTS) and Glasgow coma score(GCS) were recorded at the time of the initial examination. RESULTS: Three of the 39 children(8%) demonstrated a characteristic finding at CT which was described as the hypoperfusion complex. The 'hypoperfusion complex' was present in the 3 of the 39 traumatized children(8%), but was the main radiographic finding in the 3 of the 14 children with a severe pediatric trauma score(PTS<8) and in the 3 of the 6 children with a Glasgow coma score(GCS<8) who were examined with CT. CONCLUSION: The CT finding in all children with the hypoperfusion complex by definition included marked, diffuse dilatation of the intestine with fluid; abnormally intense contrast enhancement of the bowel wall, mesentery, kidney and/or pancreas; decreased caliber of the abdominal aorta and inferior vena cava(IVC); and moderate to large peritoneal fluid collection. This 'hypoperfusion complex' is a relatively rarely observed in injured children but appears to be associated with severe injury and a poor outcome. The pediatric trauma score provides a useful profile of injury severity in children. Prompt diagnosis of hypovolemic shock is important so that supportive therapy can be instituted to prevent further metabolic abnormalities and their potential cardiotoxic effects. In summary, the intense multiorgan enhancement pattern seen in the hypoperfusion complex indicates tenuous hemodynamic stability and is associated with a poor outcome.

PURPOSE: Tension free vaginal tape, which has become the common therapy for female stress urinary incontinence, has a complication associated with a blind passage. Transobturator vaginal tape inside-out (TVT-O) is a technique for the passage of the tape through the obturator foramens from inside to outside. We intend to evaluate the efficacy and safety of the TVT-O. MATERIALS AND METHODS: From September 2004 to December 2004, 35 patients underwent TVT-O under spinal anesthesia. Among them, 30 patients have been followed-up more than 12 months. The preoperative assessment included past history, physical examination, voiding diary, 1-hour pad test, urinalysis, voiding cystourethrography (VCUG), urodynamic study. Post-operatively a 16 Fr urethral Foley catheter was left for 24 hours. The procedural outcome, subjective satisfaction and complications were assessed retrospectively. RESULTS: The mean operative time was 15 minutes (range 12~20). Average hospital stay was 3.5 days (range 2~14). No intraoperative or postoperative complications were noted. One patient had immediate voiding difficulty, which was resolved after 2 weeks of clean intermittent catheterization. Three out of 10 patients (30%) with urge incontinence improved after the operation. The mean followed-up period was 13 months. Of 30 patients, 29 patients (96.6%) were cured and 1 patient (3.3%) improved. Subjective cure was present in 29 patients (96.6%). CONCLUSION: TVT-O is a simple, safe and effective surgical treatment for female stress urinary incontinence. However, a longer follow-up will be necessary to determine its long-term effect.

PURPOSE: Laparoscopic pyeloplasty is an alternative, minimally invasive approach for the repair of an ureteropelvic junction obstruction (UPJO). However, it has a technical difficulty, and various laparoscopic approaches are available. We present our initial experience of laparoscopic pyeloplasty using a transperitoneal approach in patients with an UPJO. MATERIALS AND METHODS: Between January 2002 and January 2004, 11 patients underwent laparoscopic pyeloplasty using a transperitoneal approach. Of these 11, 10 patients were followed up and enrolled in this study. They were comprised of 6 males and 4 females, with a mean age of 44 years (19-62). The chief complaints were flank pain in 8 patients, with a further 2 incidental detected. Three patients had had previous abdominal surgeries. The mean length of stricture was 1.1cm in the radiologic studies, and the degree of hydronephrosis was grade 3/4 in 6 patients and grade 4/4 in 4. An obstructive pattern in the 99mTc-MAG3 renal scan was present in 9 patients. RESULTS: Eight patients were treated with dismembered Anderson-Hynes pyeloplasty and 2 patients with Fenger pyeloplasty. The mean operating time and hospital stay were 225 minutes (120-450) and 7.4 days (5-10), respectively. During the operation, crossing vessels were found in 4 patients and an ureteral polyp in 1. One patient had an ascending colon injury, which was postoperatively detected and repaired. The mean follow- up period was 42.5 weeks (26-135). Follow-up excretory urography and a 99mTc-MAG3 renal scan showed improvements in 8 of the 10 patients (80%) at the 3 month follow-up. The flank pain disappeared in all the patients (100%) who had previously complained of this symptom. CONCLUSIONS: Laparoscopic pyeloplasty could be an alternative treatment for an ureteropelvic junction obstruction, especially using a transperitoneal approach, which seems to have a technical convenience over that of the retroperitoneal approach.

A complicated urachal cyst requires surgical excision to prevent symptom recurrence and complications, most notably malignant degeneration. However, a traditional open excision is associated with significant morbidity and prolonged convalescence, especially in children. A seven year old male, with a complicated urachal cyst, underwent a laparoscopic excision of the urachal remnant. Through a transperitoneal approach, using three ports, the urachus was excised and separated from the bladder dome. We report our experience of a laparoscopic excision of an urachal cyst, with a review other reports, to find the efficacy and outcome of this approach as a minimally invasive alternative.

Most adenocarcinomas of the colorectum arise in a visible benign precursor lesion, the adenoma, which is a monoclonal proliferation of dysplastic nonmalignant epithelial cells. Adenoma-adenocarcinoma sequence has been represented as the predominat pathogenetic pathway. But a small flat depressed colon cancer is characterized by non-polypoid growth pattem with no association of adenomatous tissues, which has tendency to early submucosal invasion and lymph node metastasis even in very small lesion (<10 mm). It supports de novo carcinogenesis of colorectal cancer, although most colorectal cancerarise in pre-existing adenoma. We report a case of small float colon adenocarcinoma arising in normal colonic epithelium rather than adenomatous polyp in familial adenomatous polyposis syndrome.

BACKGROUND: Cardiopulmonary exercise test is a useful test for the evaluation of the cardiovascular and respiratory systems. Obese subjects have an increased resting metabolic rate (VO2) compared to non-obese subjects and the increase is more marked during dynamic exercise, which results in the limitation of maximal exercise in obese subjects. In this study, the influence of the obesity and fat distribution on the maximal exercise capacity were evaluated. METHODS: Maximal exercise capacity was represented by maximam maximum oxygen uptake and VO2 max in the cardiopulmonary test. Obesity, total fat content and abdominal obesity(waist to hip ratio, WHR) were measured by bioelectrical impedence method. Total of 42 volunteers(male 22, female 20) were evaluated. RESULTS: 1) Weight to height ratio(mean±SD) was 110%±14.9% in men and 100±11.1% in women. 2) Fat ratio(mean±SD) was 23.3±5.2% in men and 27.55±3.9% in woman. 3) Waist to hip ratio(mean±SD) was 0.85±0.04 in men and 0.8±0.03 in woman. 4) In men, VO2max/min/Kg was negatively correlate with obesity, fat ratio, and abdominal fat distribution. 5) In woman, VO2max/Kg was negatively correlated with obesity and fat ratio, but did not show significant relationship with abdominal fat distribution. CONCLUSION: Obesity was a limiting factor for maximal exercise in both men and women. Abdominal obesity was a limiting factor for maximal exercise in men but its implication to women needs further evaluation.

BACKGROUND AND OBJECTIVES: Because the exercise treadmill test (ETT) based on ST-segment analysis is limited due to low sensitivity and specificity, there has been an interest in the additional analysis of high-frequency components of QRS (HFQRS) for the detection of coronary artery disease (CAD). We sought to evaluate the feasibility and clinical usefulness of HFQRS analysis during exercise stress echocardiography (ESE). SUBJECTS AND METHODS: We evaluated 175 patients (age 57+/-9,118 men) who performed ESE and either coronary computed tomographic angiography or coronary angiography. ETT was performed using the HyperQ stress system for both conventional ST-segment analysis and HFQRS intensity analysis. RESULTS: Thirty-two patients (31%) had significant CAD. The sensitivity and specificity of HFQRS analysis were 68.8% and 74.8%, respectively. The combined model, including HFQRS analysis and ESE, provided the best diagnostic accuracy, with the area under the receiver-operating characteristics curve (AUC) of 0.948 {95% confidence interval (CI)=0.913-0.984} compared with ST-segment analysis (AUC 0.679, 95% CI=0.592-0.766). CONCLUSION: HFQRS analysis during ESE is feasible and may provide additional diagnostic information for the detection of significant CAD.

Gastritis cystica profunda (GCP) is a rare disease in which hyperplastic and cystic dilatation of the gastric mucous glands extend into the tissues beneath the submucosa. GCP is mainly observed at the site of a gastroenterostomy; however, it may occur in the stomach without a previous history of surgery. GCP may present not only as a submucosal tumor or as solitary or diffuse polyps but also rarely as a giant gastric mucosal fold. In a patient without a previous history of surgery, GCP presents mainly as a sessile polypoid protrusion or as a submucosal tumor. In addition, GCP presents with non-specific symptoms and is most commonly found incidentally. We present a case of GCP that developed upper gastrointestinal bleeding and showed a long stalk and a focal ulcerative lesion on the surface of a polyp that developed in the stomach without a history of previous surgery. This lesion was removed by the use of an endoscopic polypectomy and was histologically diagnosed as GCP.

PURPOSE: This study was done to explore communication between nurses during preceptorship. METHODS: A qualitative study, using content analysis was conducted. Semistructured interviews were held with 10 nurses working in urban hospitals. RESULTS: A total of 226 significant statements were selected from the data and classified into 4 categories and 23 subcategories. Communication experiences of new nurses' own performance were responses to reproach - acceptance and apology, and unresponsiveness due to feeling small and uncomfortable; responses to questions - misanswer; responses to directions - unconditional acceptance. Communication experiences of new nurses' performance by nurse preceptors were kindness, stigmatization, talking behind one's back, criticism and reproach, impolite words, and emotional expression. Communication experiences of nurse preceptors's own performance were directives, sympathy, reproach, unkindness, authoritative strictness, and nonverbal expression: being cold, and lessening of tension. Communication experiences of nurse preceptors' performance by new nurses were response to criticism - recognition and apology for mistakes, evasion of responsibility, and excuses; responses to explanations-active acceptance, and difficulty with communication due to lack of comprehension. CONCLUSION: These results provide deep understanding of nurses' communication during preceptorship and should help in developing comprehensive education programs for preceptor nurses and new nurses.

PURPOSE: To compare the precise roles of high-resolution computed tomography (HRCT) and fiberoptic bronchoscopy (FOB) in the evaluation of patients presenting with hemoptysis and to determine the optimal timing for HRCT. MATERIALS AND METHODS: The results of HRCT and FOB were compared in 23 patients (15 men, 8 women) presenting with hemoptysis. Etiologies included bronchietasis (n=4), parenchymal pulmonary tuberculosis (n=4), lung cancer (n=4), endobronchial tuberculosis (n=2), and broncholithiasis (n=2). Hemoptysis was proved to be due to miscellaneous causes in an additional three cases and to be cryptogenic in four. The diagnostic results of FOB performed before and after HRCT were compared as were those of HRCT performed within and after the first 48 hours of active bleeding. RESULTS: FOB and HRCT offered a correct diagnosis in 39% and 65% of cases, respectively (p=0.005). HRCT demonstrated three cases of bronchiectasis and three of parenchymal pulmonary tuberculosis which were beyond the range of a bronchoscope. In two of five cases in which HRCT findings were nonspecific, chondromatous hamartoma and lung cancer were confirmed by FOB. In cases where HRCT was performed prior to FOB, the latter demonstrated the location and diagnosis in 82% and 47% of cases, respectively (p=0.303) ; when HRCT was performed after FOB, HRCT was correct in 67% and 17% of cases, respectively (p=0.178). In none of three cases (0%) in which HRCT was performed during the first 48 hours of active bleeding did the procedure allow a specific diagnosis. In 15 of 20 (75%) cases in which HRCT was performed after the first 48 hours, however, the diagnosis provided by CT was correct. CONCLUSION: The results of this study suggest that in patients presenting with hemoptysis, both HRCT and FOB should be used for evaluation, since they are diagnostically complementary. FOB is more useful for the diagnosis of endobronchial lesion, and HRCT for bronchiectasis and parenchymal pulmonary tuberculosis. If, in cases of hemoptysis, initial diagnosis is attempted within the first 48 hours of active bleeding, FOB should be the initial step, and HRCT images should not be obtained until active bleeding has been shown on plain chest radiograph to have abated. If this initial approach takes place after the first 48 hours of active bleeding, FOB and HRCT are equally suitable.
