  • Purpose: Traumatic rupture of the diaphragm is not easy to diagnose and often delayed. Delayed diagnosis of diaphragmatic rupture accompanied by higher chances of strangulation of herniated viscera which may result in higher morbility and mortality. The purpose of this study was to evaluate diagnostic accuracy of spiral CT, MRI and US for the diagnosis of diaphragmatic rupture in an animal model. Materials and Methods: Small, medium, and large sized transabdominal diaphragmatic ruptures were surgically made in experimental rabbits and then followed up with spiral CT, MR!, and US at 1 day, 3 day, and 1 week after operation. Results: US was superior to MR! or spiral CT in diagnosis of diaphragmatic rupture(P(0.05). The sensitivity and specificity were 94.4% and 92.9% for US, 54.0% and 85.7% for MRI, and 46.0% and 78.6% for spiral CT, respectively. The size of laceration was not related to diagnostic sensitivity in US. Sensitivity of MRI and spiral CT increased as the size of laceration were larger, but no statistical significance was present(P>0.05). All experimental animals developed pleural effusion or hemothorax one day after operation. In acute phase, US and MRI were more sensitive than spiral CT in detecting diaphragmatic rupture. Spiral CT was more sensitive than US and MRI in delayed phase but without statistical significance(P>0.05). In the experimental rabbits with accompanying visceral hernia through the diaphragmatic defect, diagnostic accuracy was found equally high among three image modalities(P>0.05). Conclusion: This study indicates that US is the most accurate diagnostic method in detecting injury to the diaphragm in a rabbit model. The findings obtained in this experimental study can be applied to the diaphragmatic rupture of human being.

  • Purpose : To find the MR findings and evaluate the usefulness of MR in flexor hallucis longus(FHL) dysfunction. Materials and Methods : From 1992 to 2003, fourty patients were found to have surgically confirmed FHL dysfunction. 24 cases of 22 patients who had performed MR were included in this study. We analyzed the signal intensity of FHL tendon and muscle, tendon sheath, sheath effusion, and bone lesions, retrospectively. Results : Non-specific, increased sheath effusion of FHL tendon was seen in 12 cases (50%). Large amount of sheath effusion(grade 3) was observed in 5 cases (21%). The signal intensity of FHL tendon was normal in all cases. High signal intensity at the FHL muscle, proximal to musculotendinous junction was seen in 1 case (4%). One case (4%) of marrow edema of the talus and another one case (4%) of osteochondritis dissecans of the talus was seen. Conclusion : Non-specific, increased sheath effusion of FHL tendon was observed on MR in FHL dysfunction patients. Therefore, MR has a limited role in diagnosis of FHL dysfunction and is useful to exclude other bone and tendon diseases causing medial ankle pain.

  • The purpose of this study was to investigate the relationship between horizontal morphology of lateral pterygoid muscle and onset of temporomandibular joint disorders. Randomly selected 150 subjects, assigned with equal number in terms of gender and age group, were included. The axial and sagittal images in their magnetic resonance images of the temporomandibular joints were used to measure the morphologic characteristics of lateral pterygoid muscles and temporomandibular joints. The measurement variables were maximal horizontal width and insertion angle to the condyle, position of the articular disc, condylar deformity, and joint effusion. In addition, presence or absence of the temporomandibular joint pain was examined through history and palpation of the joints. The relationships among measurement variables were analyzed and the results were as follow. The insertion angle of the lateral pterygoid muscle to the condyle was higher in the joint of anterior disc displacement without reduction than that in the joint of normal disc position. In addition, the maximal horizontal width of the lateral pterygoid muscle was significantly increased in joints with pain than those without pain. Also, the insertion angle was significantly higher in younger age group and the maximal width was significantly greater in male than in female. These results suggest that high insertion angle of lateral pterygoid muscle might be an important anatomic predisposing factor for anterior disc displacement in temporomandibular joint and muscular activity of lateral pterygoid muscle might be affected by preauricular pain. In conclusion, there might be a bi-directional interaction between lateral pterygoid muscle and joint in the progression of anterior disc displacement in temporomandibular joint.

  • Background: To review the middle and long term results of aortic valve replacement(AVR) for 11 years, we surveyed and followed up the patients who underwent AVR. Material and Method: Between Feb. 1986 and May 1997, 134 patients underwent AVR. The patients consisted of 71 men and 63 women whose mean age was 38.9 years, ranging from 17 to 70. Result: The concomitant operations were 62 mitral valve replacement(MVR), 14 MVR + tricuspid valve annuloplasty, 10 Cabrol operation, 16 aortic annulus widening, and so forth. We used 119 mechanical(75 St. Jude Medical, 38 CarboMedics, 6 Sorin) and 15 tissue (Carpentier-Edwards) valves. Early postoperative complications occurred in 35 cases; 9 congestive heart failure, 6 low cardiac output, 5 postoperative bleeding, 5 pleural effusion, and so forth. There were 13 early postoperative deaths(9.7%) due to low cardiac output(5), CHF (2), disseminated intravascular coagulopathy(2), and so forth. The cumulative total follow-up period was 452.7 patient-years with a mean of 3.4${\pm}$3.1 years/patient. There were 9 cases of valve-related complications; anticoagulant-related bleeding(4), prosthetic valve endocarditis(2), thromboembolism(2) and prosthetic valve failure(1) occured at rate of 0.9, 0.4, 0.4, 0.2%/ pt-yr, respectively. Late valve-related death occurred in 3 cases(2.0%/pt-yr) associated with anticoagulant-related bleeding(2) and prosthetic valve endocarditis(1). Conclusion: Actuarial survival rate by Kaplan-Meier method was 91.0${\pm}$4.3 % at 11 years.

  • Purpose : The early diagnosis of Kawasaki disease (KD) is difficult sometimes, especially in atypical or incomplete cases presenting 4 or less principal clinical features without coronary arterial lesions (coronary arterial ectasia or aneurysm). The authors investigated the incidence of echocardiographic abnormalities in patients with KD to discover whether abnormal echocardiographic findings might be helpful in the early diagnosis of KD. Methods : Echocardiography was done in the acute stage of 103 patients with KD (Kawasaki group) and 40 patients with other acute febrile illnesses (control group). Abnormal echocardiographic findings were classified into 4 categories and defined as follows; 1) significant pericardial effusion, 2) significant valvular dysfunctions, 3) left ventricular systolic dysfunction, 4) coronary arterial ectasia or aneurysm. Results : In the Kawasaki group, significant pericardial effusion was present in 24 patients (23.3 percent), significant valvular dysfunctions in 30 patients (29.1 percent), left ventricular systolic dysfunction in 10 patients (9.7 percent), and coronary arterial lesions in 27 patients (26.2 percent). In the control group, significant pericardial effusion was present in only one patient (2.5 percent). The number of patients with any one of echocardiographic abnormalities was 57 (55.3 percent) in Kawasaki group and one (2.5 percent) in control group. The sensitivity of echocardiography in the diagnosis of KD was 55.3 percent, the specificity 97.5 percent, the positive predictive value 98.3 percent, and the negative predictive value 45.9 percent. Conclusion : If abnormal echocardiographic findings, even if other than coronary arterial lesions, are confirmed in patients in whom KD is suspected, it seems desirable to inifiate specific treatment for KD.

  • Purpose: Mycoplasma pneumoniae infection is relatively common in childhood. Its extrapulmonary manifestations have been reported so much, but hepatitis associated with it has not been studied yet until now in Korea. Methods: We performed the prospective study of 19 cases that had AST and ALT>50 IU/L respectively without evidence of hepatitis A, B, C, cytomegalovirus, and Ebstein-Barr virus infections amongst 143 patients with M. pneumoniae pneumonia who were admitted to the Department of Pediatrics, Seoul Red Cross Hospital from Jan. 1999 to Dec. 2000. Results: 1) Hepatitis occurred in 13.3% of Mycoplasma pneumoniae infection, especially in fall and winter times. The average age was 4.86 years and male to female ratio was 2.2:1. 2) Vomiting was developed in 21.1%, diarrhea in 36.8%, and hepatomegaly in 21.1%, respectively. And leukocytosis was noted in 21.1%, eosinophilia in 15.4%, anemia in 10.5%, and thrombocytosis in 5.3%, respectively. The average level of C-reactive protein was $6.34{\pm}4.82$ mg/dl. 3) There was no hyperbilirubinemia, but hypoalbuminemia was detected in 42.1%. The average serum levels of AST and ALT were $214.05{\pm}183.22$ IU/L and $284.16{\pm}286.84$ IU/L, respectively. 4) Chest radiology showed lobar or lobular consolidation in 73.7%, bronchial infiltration in 26.3%, and pleural effusion in 31.6%. 5) The average length of hospitalization was 7.9 days, and the average length of normalization of serum transaminases was 8.8 days. All patients recovered within 2 weeks completely. Conclusion: The prognosis of M. pneumoniae hepatitis is good. However, its incidence is not so low that liver function should be considerately checked in case of M. pneumoniae infection.

  • Background : PCR technique is useful in diagnosis of pulmonary tuberculosis. But, its sensitivity and specificity is some different among several studies. Our aim is compare our PCR results with other's previous PCR results in AFB smear negative patients. Methods : PCR were performed in patients that their disease were suspected as active pulmonary tuberculosis and that their initial serial sputum AFB smear results were negative. Total number of patients studied by PCR technique was 177. Also, we analyzed the data only in patients whose bronchial washing fluid AFB smear was negative. And the primer had been used was IS 6110. Results : In our retrograde study, the number of patients who are diagnosed as having active pulmonary tuberculosis, inactive pulmonary tuberculosis and nontuberculous pulmonary disease was 99, 28, 50, respectively. In the sputum study, the sensitivity of PCR is 41.5% (27 PCR positive cases/65 active TBc cases). And the sensitivity of TB culture is 53.8% (35 TB culture positive cases/65 active TBc cases). In the bronchial washing specimen study, the sensitivity of PCR is 53.8% (21 PCR positive cases/39 active TBc cases). And the sensitivity of TB culture is 43.6% (17 TB culture Positive cases/39 active TBc cases). The specificity of PCR in our study is 94.9%. (74 PCR negative cases/78 inactive TBc or nontubereulous cases) In the cases of patients who were never takened anti-TBc medication, the sensitivity of PCR (45.6%--25 positive cases/55 cases) is some lower than culture (58.2%--32 positive cases/55 cases). In the cases of patients who had been takened anti-TBC medication. the sensitivity of PCR (60%--18 positive cases/30 cases) is some superior than culture (50%--15 positive cases/30 cases). Conclusion : We think that PCR results in cases of sputum AFB smear negative patients is nearly same as culture. And PCR is especially useful in patients who had been takened anti-TBc medication on admission.

  • Failure of mitral valve repair sometimes may be ascribed to severe or progressive alteration of the subvalvar apparatus. The aim of this study was to evaluate the effects of new chordae formation on mitral repair. Material and Method: From March 1997 to february 1999, 26 patients underwent mitral valve repairs with new chordae formation, we compared the symptoms and echocardiographic findings checked at preoperative state, and intraoperative period, discharge, and their last OPD visit. There were 45 male, and 11 female patients, and their mean age was 51.2$\pm$43.4 years. Etiology of the lesions was degenerative (18), rheumatic (6), infective (1) and ischemic (1). Chordal lesions were caused by rupture (18), elongation (6), and a combination of two causes (2). Associated lesions included atrial septal defect (2), tricuspid insufficiency (7), aortic insufficiency(4), and a combination of previous two factors (2). The number of mean artificial chordae was 3.6$\pm$1.6. Annuloplasty was per-formed in all cases. The CPB time was 182,1$\pm$63.7 minutes and the ACC time was 133.1$\pm$45.6 minutes. Aver-age follow up period was 49.2$\pm$7.1 months. Result: There was no early death. Early reoperation was performed in bud patients, one patient received mitral valve replacement because of an abnormality of annuloplasty and ano-ther received pericardiostomy due to postoperative pericardial effusion. During the follow up of 49.2$\pm$7.1 moths, there was no late mortality. Postoperative NYHA functional class checked at last OPD visit was class I in 22 patients (88%), class II in 2 (8%), and class III in 1 (4%). Regarding the late echocardiogram MR was absent in 20 patients (78%), 1 in 4 (15%), and II in 1 (4%). The postrepair mitral valve area was 2.2$\pm$0.35 $\textrm{cm}^2$ Conclusion: This study suggests that mitral valve repair using new chordae formation provides good early and mid term survivals and functional improvement. We think that the artificial chorda formation with polytetrafluoroethylene suture might be safe and effective technique for mitral valve repair.

  • Purpose : This study was designed to document the etiologies and the characteristics of parapneumonic effusion in children. Methods : During a 17-year period from 1987 to 2004, parapneumonic effusion was confirmed in 86 children at Gyeongsang National University Hospital. The clinical records of these children were reviewed and radiological findings and laboratory data, especially results of thoracentesis, were analyzed retrospectively. Results : M. pneumoniae(34 subjects) was the most common pathogen at all over age, especially above 1-years-old. There were diagnosed with clinical characteristics and serologic tests. The $2^{nd}$ most common pathogen revealed non tuberculous bacteria(14 subjects). A species of bacteria at no tuberculous bacteria revealed S. aureus(5), S. pneumoniae(3), P. aeroginosa(3), other staphylococcus (2), and K. pneumoniae(1). There were confirmed with sputum culture or pleural fluid culture or blood culture. S. aureus was most common pathogen in infants. The $3^{rd}$ common pathogen was M. tuberculosis(7). There were confirmed with skin tuberculin tests and AFB stains. Another that was classified as a non bacteria was adenovirus(2). Complications of parapneumonic effusion such as pleural thickness occurred on M. tuberculosis(1). Non tuberculous bacteria, especially S. aureus revealed a serious predominance of polymorphocyte at pleural fluid, and lowest pleural pH and glucose, and highest pleural protein and LDH. Tuberculosis revealed high pleural protein and LDH. Conclusion : Age and chemistries of pleural fluid might be helpful in differentiating various etiologies of parapneumonic effusion. If there were suspicious of tuberculosis and non-tuberculous bacteria, more aggressive approaches were needed to prevent complication.
