Purpose: The appropriate management of traumatic truncal arterial injury is often difficult to determine, particularly if the injury is associated with severe additional truncal lesions. The timing of repair is controversial when patients arrive alive at the hospital. Also, there is an argument about surgery versus stent-graft repair. This study's objective was to evaluate the appropriate method and the timing for treatment in cases of truncal abdominal injury associated with other abdominal lesions. Methods: The medical records at Ajou University Medical Center were reviewed for an 8-year period from January 1, 2001, to December 31, 2008. Twelve consecutive patients, who were diagnosed as having had a traumatic truncal arterial injury, were enrolled in our study. Patients who were dead before arriving at the hospital or were not associated with abdominal organ injury, were excluded. All patients involved were managed by using the ATLS (Advanced Trauma Life Support) guideline. Data on injury site, the timing and treatment method of repair, the overall complications, and the survival rate were collected and analyzed. Results: Every case showed a severe injury of more than 15 point on the ISS (injury severity score) scale. The male-to-female ratio was 9:3, and patients were 41 years old on the average. Sites of associated organ injury were the lung, spleen, bowel, liver, pelvic bone, kidney, heart, vertebra, pancreas, and diaphragm ordered from high frequency to lower frequency. There were 11 cases of surgery, and one case of conservative treatment. Two of the patients died after surgery for truncal organ injury: one from excessive bleeding after surgery and the other from multiple organ failure. Arterial injuries were diagnosed by using computed tomography in every case and 9 patients were treated by using an angiographic stent-graft repair. There were 3 patients whose vessels were normal on admission. Several weeks later, they were diagnosed as having a truncal arterial injury. Conclusion: In stable rupture of the truncal artery, initial conservative management is safe and allows management of the major associated lesions. Stent grafting of the truncal artery is a valuable therapeutic alternative to surgical repair, especially in patients considered to be a high risk for a conventional thoracotomy.

In Pusan Paik Hospital, Inje University, we experienced 174 cases of pulmonary resections for pulmonary tuberculosis from Jun. 1979 to Feb. 1990. In all of them automatic stapling devices were used for division of lung parenchyme and /or bronchial closure. The results were as follows; l. In 174 cases[male 100, female 74], third and fourth decades were 116 cases [66.7%]. 2. Indications for lung resection in the radiographic findings were destroyed lung 47 cases[27.0%], destroyed lobe 42 cases[24.1%], cavitary lesions 42 cases[24.1%], tuberculoma 22 cases[12.7%], and bronchial lesions 21 cases[12.1%]. 3. The mean of staplers used in the operations was 1.6, and possible stapler-associated complications were only 2 cases of bronchopleural fistula after pneumonectomy. 4. Twenty-seven of 36 patients with bilateral lesions and 52 of unilateral ones on chest X-ray films were AFB positive on preoperative sputum smears. Twenty-three[85.2%] of bilateral lesions and 51[98.1%] of unilateral ones were AFB negative at 6 months after operations. 5. Main complications of resections were operative death 1[0.6%], empyema 4[2.3%], respiratory insufficiency 3[1.7%], pleural dead space 5[2.9%], and bronchial spreading of tuberculosis 2[1.1%]. Bronchopleural fistula were only 2 cases after pneumonectomy and none after lobectomy or segmentectomy. 6. One hundred and forty two patients[92.8%] of 153 with available follow-up data were in the state of good quality of life.

Footpad dermatitis (FPD) can be considered as a threat for poultry production due to it causes losses due to condemnation in slaughterhouse. The prevalence and the severity of FPD in broiler breeders increase over time with development of poultry industry. The condition is produced by multifactorial including include drinker design and management, diet composition, house (temperature and humidity levels), litter (type, quality, and quantity) and gut health. Bacterial infections can be associated. FPD lesions can develop in less than a week. FPD is a variable size of inflammatory lesion of the footpad in commercial poultry characterized by necrotic lesions on the plantar surface of the footpad of poultry. These lesions can be exposed after removal of fecal mass and litter stuck on it. There are considerable and numerous interactions between the environment and the genetic traits. Prevention depends mainly on improvement of litter condition. Genetic selection against footpad dermatitis must be contributed to reduce pain and suffering for particular bird experiencing contact dermatitis as well as to avoid economic losses. The objective of this review is to collect different literature written about FPD to be available to students, researchers and veterinarian in poultry practical.

Kawasaki disease (KD) is a systemic vasculitis in infants and young children. However, its natural history has not been fully elucidated because the first case was reported in the late 1960s and patients who have recovered are just now entering middle age. Nevertheless, much evidence has raised concerns regarding the subclinical vascular changes that occur in post-KD patients. KD research has focused on coronary artery aneurysms because they are directly associated with fatality. However, aneurysms have been reported in other extracardiac muscular arteries and their fate seems to resemble that of coronary artery aneurysms. Arterial strokes in KD cases are rarely reported. Asymptomatic ischemic lesions were observed in a prospective study of brain vascular lesions in KD patients with coronary artery aneurysms. The findings of a study of single-photon emission computed tomography suggested that asymptomatic cerebral vasculitis is more common than we believed. Some authors assumed that the need to consider the possibility of brain vascular lesions in severe cases of KD regardless of presence or absence of neurological symptoms. These findings suggest that KD is related with cerebrovascular lesions in children and young adults. Considering the fatal consequences of cerebral vascular involvement in KD patients, increased attention is required. Here we review our understanding of brain vascular involvement in KD.

Objective: To assess the contrast-enhanced CT and ultrasonography (US) findings of intracholecystic papillary neoplasm (ICPN) and determine the imaging features predicting ICPN associated with invasive carcinoma (ICPN-IC). Materials and Methods: In this retrospective study, we enrolled 119 consecutive patients, including 60 male and 59 female, with a mean age ± standard deviation of 63.3 ± 12.1 years, who had pathologically confirmed ICPN (low-grade dysplasia [DP] = 34, high-grade DP = 35, IC = 50) and underwent preoperative CT or US. Two radiologists independently assessed the CT and US findings, focusing on wall and polypoid lesion characteristics. The likelihood of ICPN-IC was graded on a 5-point scale. Univariable and multivariable logistic regression analyses were performed to identify significant predictors of ICPN-IC separately for wall and polypoid lesion findings. The performances of CT and US in distinguishing ICPN-IC from ICPN with DP (ICPN-DP) was evaluated using the area under the receiver operating characteristic curve (AUC). Results: For wall characteristics, the maximum wall thickness (adjusted odds ratio [aOR] = 1.4; 95% confidence interval [CI]: 1.1-1.9) and mucosal discontinuity (aOR = 5.6; 95% CI: 1.3-23.4) on CT were independently associated with ICPN-IC. Among 119 ICPNs, 110 (92.4%) showed polypoid lesions. Regarding polypoid lesion findings, multiplicity (aOR = 4.0; 95% CI: 1.6-10.4), lesion base wall thickening (aOR = 6.0; 95% CI: 2.3-15.8) on CT, and polyp size (aOR = 1.1; 95% CI: 1.0-1.2) on US were independently associated with ICPN-IC. CT showed a higher diagnostic performance than US in predicting ICPN-IC (AUC = 0.793 vs. 0.676; p = 0.002). Conclusion: ICPN showed polypoid lesions and/or wall thickening on CT or US. A thick wall, multiplicity, presence of wall thickening in the polypoid lesion base, and large polyp size are imaging findings independently associated with invasive cancer and may be useful for differentiating ICPN-IC from ICPN-DP.

목적: 가와사끼병(Kawasaki disease, KD)은 여러 기관을 침범하여 다양한 임상적 징후를 나타낸다. 임상적 징후들의 중증도와 관상동맥병변(coronary artery lesion, CAL)과의 연관성은 잘 알려져 있지 않다. 본 연구는 심한 피부병변이나 관절염을 가진 환자군들이 나타내는 임상 양상들과 CAL의 발생 위험도를 평가하고자 하였다. 방법: 면역글로불린을 투여 받은 KD 환아 220명을 대상으로 후향적으로 조사하였다. 심한 피부병변이 있는 환자군(52명)과 경하거나 피부 병변이 없는 환자군(168명), 관절염이 있는 환자군(6명)과 관절염이 없는 환자군(124명)간의 임상 양상 및 검사실 소견을 각각 비교하였다. 결과: 전체 환자들의 평균 나이는 $2.23{\pm}1.87$세였고 남아와 여아의 비는 1.5:1 (138/82)이었다. 220명 중에 52명(23.6%)은 CAL을 동반하였고 29명(13.2%)은 비전형적 KD를 보였다. CAL을 동반한 군이 나이가 많고 발열 기간이 길었으며 면역글로불린 치료에 반응하지 않는 비율이 높았다. 심한 피부 병변을 가진 환자군은 심한 피부 병변이 없는 환자군보다 평균 나이가 많고(P<0.001), 발열 기간이 길고(P=0.041), CAL 발생율이 높았으며(P=0.033), neutrophil 및 neutrophil-to-lymphocyte ratio 수치가 높았다(P=0.031, P=0.001). 관절염이 있는 환자군은 methylprednisolone 또는 infliximab으로 더 많이 치료를 받게 된 경향이 있었다. 결론: 가와사끼병에서 CAL의 발생 빈도는 심한 피부병변이 있는 군에서 더 높았다. 본 연구는 피부 병변, 경부 림프절병, 관절염과 같은 가와사끼병의 임상적 징후의 중증도가 CAL의 위험도와 연관성이 있을 것이라 제안한다.

Background: Endobronchial ultrasonogram (EBUS) has increased the diagnostic yield of a bronchoscopic biopsy of peripheral pulmonary lesions (PPL). This study evaluated the diagnostic yield of EBUS-guided transbronchial biopsy (TBB) and the visibility of EBUS PPL. Methods: Between August 2007 and November 2008, 50 patients (32 men and 18 women, median age, 61.1${\pm}$10 yrs; range, 16 to 80 yrs) whose PPL lesions could not be detected with flexible bronchoscopy were enrolled in this study. Among the 50 patients, 40 cases were malignant lesions (adenocarcinoma 25, squamous cell carcinoma 10, small cell carcinoma 5) and 10 cases were benign lesions (tuberculoma 7, fungal ball 1, other inflammation 2). Results: The mean diameter of the target lesion was 35.4${\pm}$4.3 mm. Of the 50 patients examined, the overall diagnostic yield by EBUS-TBLB was 46.0% (23/50). The visualization yield of EBUS was 66.0% (33/50). A definitive diagnosis of PPL localized by EBUS was established using EBUS-TBLB in 69.6% (23/33) of cases. The diagnostic yields from washing cytology and brushing cytology from a bronchus identified by EBUS were 27.0% and 45.4% respectively. The diagnostic yields reached 78.7% when the three tests (washing cytology, brushing cytology and EBUS-TBLB) were combined. The visualization yield of EBUS in lesions <20 mm was significantly lower than that in lesions ${\geq}$20 mm (p=0.04). The presence of a bronchus leading to a lesion (open bronchus sign) on the chest CT scan was associated with a high visualization yield on EBUS (p=0.001). There were no significant complications associated with EBUS-TBLB. Conclusion: EBUS-TBLB is a safe and effective method for diagnosing PPL. The lesion size and open bronchus signs are significant factors for predicting the visualization of EBUS.

Purpose: The importance of Helicobacter pylori eradication after endoscopic resection (ER) of gastric neoplasms remains controversial. In this study, we clarified the importance of H. pylori eradication for metachronous lesions after ER. Materials and Methods: This study included 3,882 patients with gastric neoplasms who underwent ER. We included patients infected with H. pylori who received eradication therapy. Among them, 34 patients with metachronous lesions after ER and 102 age- and sex-matched patients (nonmetachronous group) were enrolled. Background mucosal pathologies such as atrophy and intestinal metaplasia (IM) were evaluated endoscopically. The expression levels of CDX1, CDX2, Sonic hedgehog (SHH), and SOX2 were evaluated based on H. pylori eradication and the development of metachronous lesions. Results: The eradication failure rate was higher in the metachronous group than in the nonmetachronous group (P=0.036). Open-type atrophy (P=0.003) and moderate-to-severe IM (P=0.001) occurred more frequently in the metachronous group. In patients with an initial diagnosis of dysplasia, the eradication failure rate was higher in the metachronous group than in the nonmetachronous group (P=0.002). In addition, open-type atrophy was more frequent in the metachronous group (P=0.047). In patients with an initial diagnosis of carcinoma, moderate-to-severe IM occurred more frequently in the metachronous group (P=0.003); however, the eradication failure rate was not significantly different between the two groups. SHH and SOX2 expression was increased, and CDX2 expression was decreased in the nonmetachronous group after eradication (P<0.05). Conclusions: Open-type atrophy, moderate-to-severe IM, and H. pylori eradication failure were significantly associated with metachronous lesions. However, eradication failure was significantly associated with dysplasia, but not carcinoma, in the metachronous group. Thus, H. pylori eradication may play an important role in preventing metachronous lesions after ER for precancerous lesions before carcinomatous transformation.

A year round study was carried out to investigate the etiology, clinical signs, postmortem lesions and occurrence of naturally occurring enterotoxaemia in Black Bengal goats. Sixteen goats of different age and sex died in different seasons with sigh associated with enterotoxaemia made the materials of this study. Accidental access to large amount of concentrate was noted as one of the predisposing factors although few cases were reported to occur without known diet change. Younger animals(50%) and males(62.50%) were found more prone to the disease and it was likely to be more prevalent during winter(50%) followed by at rainy season(31.25%) and summer(18.75%). Diarrhoea(81.25%), dullness(56.25%), drooping of the ears(50%), anorexia(43.75%) were recorded as major clinical signs whereas enterocolitis(100%), lung edema(87.50%), fluid filled intestines(87.50%), enlarged mesenteric lymph nodes(56.52%) etc. were most common post mortem lesions found. A few cases showed lesions on heart(31.25%), brain(25%) and/or liver/spleen(18.75%) but no lesion was found on kidney. Thus the so called 'pulpy kidney' lesion was absent. Intestinal contents were subjected to conventional bacteriological culture based methods to identify the causal agents. Based on the morphological, cultural and biochemical properties the causal agent was identified as Clostridium perfringens. Despite the study was carried out at certain area it showed a clear picture of goat enterotoxaemia in terms of etiology, clinical signs, postmortem lesions and occurrence of goat enterotoxaemia in Bangladesh.

Background: Acute cerebral infarction is a major risk factor for postoperative neurologic complications in cardiac surgery. However, the outcomes associated with acute silent cerebral infarction (ASCI) have not been not well established. Few studies have reported the postoperative outcomes of these patients in light of preoperative Diffusion-weighted magnetic resonance imaging (DWI). We studied the postoperative neurologic outcomes of patients with preoperative ASCI detected by DWI. Methods: We retrospectively studied 32 patients with preoperative ASCI detected by DWI. None of the patients had preoperative neurologic symptoms. The mean age at operation was $68.8{\pm}9.5$ years. Five patients had previous histories of stroke. Four patients had been diagnosed with infective endocarditis. Single cerebral infarct lesions were detected in 16 patients, double lesions in 13, and multiple lesions (>5) in three. The median size of the infarct lesions was 4 mm (range, 2 to 25 mm). The operations of three of the 32 patients were delayed pending follow-up DWI studies. Results: There were two in-hospital mortalities. Neurologic complications also occurred in two patients. One patient developed extensive cerebral infarction unrelated to preoperative infarct lesions. One patient showed sustained delirium over one week but recovered completely without any neurologic deficits. In two patients, postoperative DWI confirmed that no significant changes had occurred in the lesions. Conclusion: Patients with preoperative ASCI showed excellent postoperative neurologic outcomes. Preoperative ASCI was not a risk factor for postoperative neurologic deterioration.
