Background : Bronchial anthracofibrosis is one of the main manifestations of lung disease that is related to woodsmoke inhalation, and it is frequently associated with various pulmonary diseases, such as tuberculosis. The purpose of this study was to evaluate the clinical significance of bronchial anthracofibrosis in patients with endobronchial tuberculosis. Methods : 63 patients, who were diagnosed with endobronchial tuberculosis using bronchoscopy, were included in this study. The patients consisted of 12 males and 51 females, having mean age of 59.5 years. The clinical features, radiologic and bronchoscopic findings between the patients with (37) and without (26) bronchial anthracofibrosis were analyzed retrospectively. Results : When the patients were older, bronchial anthracofibrosis was more frequent. The endobronchial tuberculosis, which was located at the right middle lobal bronchus, was more frequent in the patients with bronchial anthracofibrosis than in the patients without bronchial anthracofibrosis. In the morphologic types of endobronchial tuberculosis, patients with bronchial anthracofibrosis had more edematous-hyperemic and ulcerative types, while patients without bronchial anthracofibrosis had more active caseating. Conclusion : These findings suggest that the presence of bronchial anthracofibrosis can possibly influence the locations and morphologic types of endobronchial tuberculosis.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.

Background : To Investigate the association between bronchial anthracofibrosis (AF) and tuberculosis (TB), and the clinical utility of a polymerase chain reaction (PCR) on bronchial specimens for rapid diagno-sis of active pulmonary TB in patients with bronchial AF. Method : Thirty patients (25 women and 5 men ranging in age from 53 to 88), who were diagnosed with bronchial AF by a bronchoscopic exami-nation, were enrolled in this study. PCR targeting the IS6110 segment of Mycobacterium tuberculosis was performed on the bronchial wash fluid and anthracofibrotic bronchial tissue. The PCR results were compared with the bacteriological, histological, and clinical findings. Results : Eighteen of the 30 patients (60%) were associated with TB, nine of whom were confirmed as having active TB. The remaining 9 had a past history of TB. The sputum or bronchial aspirate AFB smear, culture, and histological findings were positive in 4 (13%), 9 (30%), and 5 (17%) patients, respectively. PCR of the AF tissue and bronchial wash fluid was positive in 5 (17%) and 11 (37%) of the 30 patients, respectively. PCR was more sensitive than the AFB smears for diagnosing pulmonary TB (22 % us 89 %, respectively, p<0.05). All 5 patients with positive AF tissue PCR results also had both histological findings and positive bronchial wash fluid PCR results. Of the 3 patients with positive PCR but negative bacteriological or histological results, 2 of these patients appeared to have active tuberculosis on a clinical basis. Conclusion: Although TB-PCR did not reveal an increased association between bronchial AF and TB compared with traditional methods, PCR on the bronchial wash fluid appears to be useful for the rapid diagnosis of pulmonary TB in patients with bronchial AF. TB-PCR on AF bronchial tissue itself did not yield additional benefits for diagnosing TB, which suggests that an AF lesion itself may not be an active or original site of the infection, but a secondary change of TB.

Background : Known as a kind of complication or a specific form of pulmonary tuberculosis, endobronchial tuberculosis caused several kinds of problems in diagnosis and managements. But the frequency of this disease are is widely variable, generally reported from as low as 10 - 20 % to as high as 40 - 50 %. We prospectively performed bronchoscopy in patients diagnosed as pulmonary tuberculosis to evaluate the frequency of endobronchial tuberculosis and its related findings. Method : From March, 1995 to February, 1996, we prospectively performed bronchoscopy in patients newly diagnosed as pulmonary tuberculosis and evaluated the frequency of endobronchial tuberculosis, its clinical features and laboratory findings including raiologic, microbiologic and physiologic aspects. Results : Number of patients diagnosed as pulmonary tuberculosis was 103 and 55 patients(53.4%) were found to have endobronchial tuberculosis. But the frequency were 43.8% in male and 76.7% in female, respectively. Frequently noted symptoms were nonspecific including cough, sputum, fever, weight loss in the order of frequency but cough was more frequent than in pulmonary tuberculosis. Physical examination showed rale, decreased breathing sound and wheezing and wheezing was more frequent than in pulmonary tuberculosis. All 7 subtypes were noted bronchoscopically and edema-hyperemia (stenotic without fibrosis) type was most frequently(32.7%) noted, and followed by chronic nonspecific bronchitis type, stenotic with fibrosis type and actively caseating type in the order of frequency. The relationship between subtypes of endobronchial tuberculosis and radiologic findings was insignificant. Right lung was involved more frequently than left lung and left upper lobe was most commonly involved site, and followed by right upper lobe and trachea. Acid-fast bacilli(AFB) positivity in sputum and / or bronchial washing fluid was 73% and suggested high risk of infectivity. Conclusion : The frequency of endobronchial tuberculosis in patients with pulmonary tuberculosis was higher than known and also suggested bronchoscopic examination to detect endobronchial involvement should be recommanded and careful management is also needed to prevent complications.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

A 7-year-old spayed female domestic shorthair cat was referred for chronic intermittent vomiting. The frequency of vomiting increased recently, and the cat showed anorexia at presentation. There were no remarkable abnormalities on the blood analyses and diagnostic imaging. However, the endoscopic examination revealed focal erosions of the gastric body mucosa, and subsequent multiple biopsies were obtained. Histopathologic examination indicated mild to moderate lymphocytic gastritis. The vomiting was completely disappeared 7 days after the administration with prednisolone (PDS). However, because of side effects caused by the long-term PDS administration, cyclosporine was added on the prescription with tapered dose of PDS. The dog's condition improved with continued cyclosporine treatment, and no further vomiting and anorexia episodes have been noted. This case describes the successful management with administration of cyclosporine in feline lymphocytic gastritis.

Tuberculous peritonitis is a rare cause of intra-abdominal infection. Although sometimes asymptomatic, most of the patients have fever, weight loss, abdominal pain, and edema. The diagnosis of tuberculous peritonitis is difficult and sometimes delayed because of confusion of the disease with other illnesses and the non-specificity of signs and symptoms. Tuberculous peritonitis is examined with ultrasonography and computerized tomogram, but confirmed by biopsy or tuberculosis culture. Ascitic fluid is exudates with a lot of lymphocytes and elevated protein. Tuberculous peritonitis is treated successfully with isoniazid, rifampicin for one year, pyrazinamide for first 2 months and streptomycin for first one month. We experienced one case of tuberculous peritonitis with transudate of ascitic fluid, confirmed by biopsy using colonoscopy, and treated successfully.

Purpose: This study was undertaken to evaluate the factors correlated with the clinical course and outcome in patients of Henoch-Sch${\ddot{o}}$nlein Purpura. Methods: The medical records of 104 children diagnosed with Henoch-Sch${\ddot{o}}$nlein Purpura (HSP) from January 1996 to April 2006 were reviewed retrospectively. The patients were divided into two groups: patients with Gastrointestinal (GI) symptoms and those without GI symptoms. When there were joint, scrotum, and renal symptoms except for skin lesion in whole HSP, those patients were excluded. The history of acute infection, duration of admission, treatment requirement, recurrence of HSP, CBC, stool occult blood test, abdominal ultrasonographic findings and GI endoscopic findings were reviewed. Results: Among 104 patients, patients with GI symptoms included 66 cases (63.5%), those without GI symptoms accounted for 38 cases (36.5%). GI symptoms included: abdominal pain in 57 cases (54.8%), vomiting 21 cases (20.2%), GI bleeding 5 cases (4.8%), nausea 3 cases (2.9%) and diarrhea 3 case (2.9%). Positive GI symptoms and GI mucosal lesions on GI endoscopy had a statistically significant correlation with increased admission duration, treatment requirement, recurrence of HSP, and positive stool occult blood. Six cases with small intestinal wall thickening were noted on abdominal ultrasonography. Six cases of hemorrhagic gastritis and hemorrhagic duodenitis, 3 cases of duodenal ulcer, 3 cases of hemorrhagic gastritis and duodenal ulcer, 2 cases of hemorrhagic duodenitis and colitis, and 1 case of colitis were noted on GI endoscopy. Conclusion: These results suggest that GI endoscopic examination may be helpful for the diagnosis and treatment of children with HSP.
