Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic orinfectious diseases in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for bothsuspected malignant and infectious disease was 79%(41/52). The primary indication for fine needle aspiration wasto document the presense of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscesses.Consequently we were convinced that the ultasound

Ultrasono-guided percutaneous catheter drainage of 28 abscesses and fluid collections was performed. In 24cases, operation was avoided and the patients were cured(24/28). Of these, 4 cases were recurred and repeatedcatheter drainage was performed. There were two failures and partial success was achieved in 2 cases; in thesepatients, operation was necessary, although the patients benefited from the percutaneous drainage. Cures andpartial successes totaled 26/28. We describe significance of the diagnostic needle aspiration, especially inpredicting the drainability of cavity contents. We review aspects of postprocedurecatheter management includingirrigation and timining of withdrawal.

A 73-year-old woman who presented with chest discomfort visited the emergency room. The 12-lead electrocardiography showed ST-segment elevation in II, III, and lead augmented vector foot. Emergent coronary angiography revealed a thrombus in the distal right coronary artery. Percutaneous coronary angioplasty with a stent was performed. After the procedure, persistent dyspnea occurred. Her chest computed tomography (CT) showed occlusion of the bilateral pulmonary artery. We could not find a source for the embolization or a hypercoagulable state. We started a course of dual antiplatelets with oral anticoagulants. Pulmonary embolism was resolved at follow-up chest CT scan. Aspirin, clopidogrel and warfarin were given for 6 months. The patient is doing well now 1 year after the episode.

BACKGROUND: Aminophylline is an inhibitor of phosphodiesterase; it increase the cAMP and, in turn, the level of acetylcholine at the neuromuscular junction. In doing so, it has an antifatigue action. It antagonizes nondepolarizing neuromuscular blockade in animals, and has been anecdotally noted to do so in humans, as well. We investigated the interaction of aminophylline and vecuronium on the dose response curve in vitro. METHODS: Institutional approval was obtained. Thirty seven male Spague Dawley rats (150~200 g) were divided into four groups (control, aminophylline 2.5, 5.0 and 7.5 microgram/ml). The animal were anesthetized with 40 mg/kg phentobarbital. The left hemidiaphragm with phrenic nerve was dissected and mounted within 5 minutes in bath containing 100 ml Krebs solution at 32oC. The phrenic nerve was stimulated at supramaximal intensity by a Grass S88 stimulator through an SIU5 isolation unit. The twitch height was measured by precalibrated Grass FT03 force displacement transducer and recorded. After stabilization of twitch response, vecuronium was added to the solution to obtained an initial concentration 1.0 microgram/ml with aminophylline 0, 2.5, 5.0, or 7.5 microgram/ml. When a stable 3~5 twitch was obtained after first dose, additional vecuronium was added to the Krebs solution in increments of 0.5 microgram/ml to achieve a more than 90% neuromuscular block. The data were analyzed by repeated measures of ANOVA and kappa2 test. RESULTS: There was a significant increase in the effective dose of vecuronium needed to depress the twitch response in aminophylline 5.0 and 7.5 microgram/ml added groups compared with control group and aminophylline 2.5 microgram/ml group. CONCLUSIONS: We conclude that aminophylline shows decreased sensitivity to vecuronium in the phrenic nerve diaphragm preparation of rats.

Acute alcoholic myopathy presented with paraparesis, myoglobinuria. And acute renal failure is an uncommon complication of alcoholism. A 34-year-old man had been a heavy alcohol drinker for a year, complained of sudden lower extremity weal; ness and swelling after heavy drinking. On examination, lower extremity was swollen and unable to move. Laboratory data showed markedly elevated GOT, LDH, CK, and myoglobinuria. Initial electrodiagnostic study was indefinite for diagnosis of myopathy and biopsy of the quadriceps muscle showed slight increased eosinophilia of sarcoplasm. But in followup study, myopathic findings and degeneration becarne apparent in electromyography and blopsy.

Since April 2009, outbreaks of the new influenza A (H1N1) virus have occurred worldwide. The spectrum of disease caused by H1N1 infection ranges from non-febrile, mild upper respiratory tract illness to severe or fatal pneumonia. Rapidly progressive respiratory diseases, such as acute respiratory distress syndrome and renal or multi-organ failure, have accounted for severely affected inpatients. Complex cases involving myocarditis, encephalitis, and myositis have been described. However, pulmonary air-leak syndrome, consisting of spontaneous pneumomediastinal emphysema, pneumothorax, and subcutaneous emphysema complicating pneumonia with the H1N1 virus, has not previously been reported in Korea. Here, we report a case of pulmonary air-leak syndrome complicating H1N1 infection that was resolved with an antiviral agent, high-flow oxygen, and fluid therapy.

Poly-L-lysine (PLL) was reported to suppress mucin release from airway goblet cells during 30 min treatment period. In this study, we investigated whether PLL consistently suppresses mucin release from cultured airway goblet cells during 24 h after 30 min treatment and also specifically suppresses the release of mucin without any effects on the other releasable glycoproteins. Confluent primary hamster tracheal surface epithelial (HTSE) cells were metabolically radiolabeled with 3H-glucosamine for 24 h and chased for 30 min in the presence of varying concentrations of PLL to assess the effects on 3H-mucin release and on the total elution profile of the treated culture medium. The total mucin content during 24 h after 30 min treatment of PLL was assesed to investigate the consistency of effects. PLL did not affect the release of the other releasable glycoproteins whose molecular weights were less than mucin, and decreased the total mucin content during 24 h after 30 min treatment. We conclude that PLL can specifically suppress mucin release from cultured airway goblet cells and the suppression on mucin release is consistent. This finding suggests that PLL might be used as a specific airway mucin-regulating agent by directly acting on airway mucin-secreting cells.

A 50-year-old male presented with acutely progressed paraplegia. His magnetic resonance imaging demonstrated two well-demarcated components with opposite signals in one cystic lesion between the T1- and T2-weighted images at the T1 spine level. The patient showed immediately improved neurological symptoms after surgical intervention and the histopathological exam was compatible with a neurenteric cyst. On operation, two different viscous drainages from the cyst were confirmed. A unique similarity of image findings was found from a review of the pertinent literature. The common findings of spinal neurenteric cyst include an isointense or mildly hyperintense signal relative to cerebrospinal fluid for both T1- and T2-weighted images. However, albeit rarer, the signals of some part of the cyst could change into brightly hyperintensity on T1-weighted images and hypointensity on T2-weighted images due to the differing sedimentation of the more viscous contents in the cyst.

BACKGROUND: There is controversy over whether aerobic or resistance exercise is more effective for improving endothelial function in type 2 diabetes mellitus (T2DM). This study was aimed to investigate the effects of an aerobic and resistance training program on endothelial function, and the influences of glycemic control, body weight changes, and aerobic capacity in T2DM. METHODS: Total 40 overweight women with T2DM were assigned into 3 groups: an aerobic exercise group (AEG, n=13), resistance exercise group (REG, n=12), and control group (CG, n=15), and followed either brisk walking for the AEG or resistance band training for the REG, 60 minutes per day, 5 days per week for 12 weeks with monitoring daily activity using accelerometers. We assessed endothelial function by flow-mediated dilation (FMD), and aerobic capacity by oxygen uptake at anaerobic threshold (AT_VO2) at baseline and following training program. RESULTS: The mean participants' age was 57.0+/-6.8 years, and body mass index (BMI) was 27.0+/-2.3 kg/m2. After intervention, FMD increased by 2.2+/-1.9% in AEG, which differed from REG and CG (P=0.002), despite of decreased body weight (BW) in both AG and RG (2.8+/-2.5%, P=0.002; 1.6+/-2.0%, P=0.017, respectively). A significant increased AT_VO2 and decreased HbA1c were found only in AEG. In all participants, FMD was changed with the significant relations to the AT_VO2 (r=0.348, P=0.035), but not to HbA1c levels or BW. CONCLUSION: Aerobic exercise appears to be more beneficial than resistance exercise for improving endothelial function in T2DM. In addition, aerobic capacity could be a better predictor of changes in FMD than BW and glycemic control.
