BACKGROUND: Bronchial asthma is characterized by noctunal dyspnea, cough and wheezing because of airway hyperresponsiveness to nonspecific stimuli. These symptoms and signs are also observed in patients with congestive heart failure. Therefore, this is so called "cardiac asthma". There are lots of experimental and clinical datas to suggest that airway dysfunctions occur in acute and chronic congestive heart failure. However, it is still controversial whether bronchial hyperresponsiveness is present in patients with congestive heart failure. To assess whether bronchial hyperresponsiveness is present in patients with congestive heart failure and to demonstrate the relationship between bronchial responsiveness and vascular pressure, we performed methacholine provocation test in 11 patients with mitral valvular heart disease. METHODS: All patients were in the New York Heart Association functional class II and treated continuously with digoxin and/or dichlozid and/or angiotensin converting enzyme inhibitor except one patient. All patients were undergone right and left side heart catheterization for hemodynamic measurements. A 20 percent fall of peak expiratory flow rate were considered as positive response to methacholine provocation test. RESULTS: 1) Only one patient who has normal pulmonary artery pressure, pulmonary capillary wedge pressure, cardiac index was positive in methacholine provocation test. 2) Their mean pulmonary artery pressure, pulmonary capillary wedge pressure were 21.72 +/- 9.70mmHg, 15.45 +/-8.69mmHg respectively which were significantly higher. CONCLUSION: It is speculated that in stable congestive heart failure patients, bronchial responsiveness as assessed by methacholine provocation test may not be increased.

Intramuscular myxoma is a rare benign myxoid tumor that is difficult to differentiate from other benign soft tissue tumors and sarcoma, and as a result, intramuscular myxoma is commonly misdiagnosed as another type of soft tissue tumor. Accordingly, awareness of the existence of this condition is a fundamental requirement for treatment decision-making. Furthermore, although intramuscular myxoma appears grossly to be well-circumscribed, it can infiltrate adjacent soft tissue microscopically. Tumor resection is the recommended treatment, but appropriate surgical margin sizes remain controversial. To the best of our knowledge, this is the first South Korean report to be issued on the treatment of intramuscular myxoma of the foot.

The lymphangioleiomyomatosis(LAM) is a rare disorder, which afflicts mainly young woman of childbearing age, characterized by proliferation of immature smooth muscle cell in the lymphatics. We experienced a case of LAM in 26-years-old pregnant woman, confirmed pathologically by inguinal lymph node biopsy. She has suffered from exertonal dyspnea and dry coughing. The symptoms and chest X-ray were aggravated with pregnancy, but improved after delivery with two times of pregnancy. The chest X-ray showed diffuse reticulonodular infiltration and chest HRCT showed diffuse scattered tiny thin-walled cyst of lung parenchyma. We noted chylous ascites of which triglyceride level is 396 mg/dl. After delivery, the symptoms were getting better. We treated with medroxyprogesterone and planned close observation and follow-up.

The purpose of this study was to evaluate the structural characteristics of the thread length of orthodontic mini-screws and the effects of insertion and removal torques according to the formation of the cutting flute. Two types of mini-screws were made, with a thread length of 6.0 mm and a thread length of 3.3 mm. In order to examine the effect of flute formation, the experiment group was divided into a miniscrew test group with flute formation and an experiment group without flute formation. To evaluate the effect of flute formation, two flutes were formed at 180°on the circumference, and at the tip of the mini screw, up to 4 mm for thread length of 6.0 mm and 2.4 mm for thread length of 3.3 mm. A biomechanical test block formed of 2 mm cortical bone and 10 mm cancellous bone was used to eliminate the influence of the difference in cortical bone thickness and bone density according to the insertion site. 1 mm diameter guide hole was drilled on the test block and the mini-screw was placed vertically. Using a 0.1 N·cm precision digital torque gauge, the maximum torque value was recorded at this time by embedding it to the top of the screw under a static load of 1.2 kg and the value when it was removed in the opposite direction. The insertion torque values for the 6.0 mm and 3.3 mm length mini screws were (29.53±1.84) N·cm and (26.84±2.15) N·cm, and the removal torque values are (14.50±1.37) N·cm and (13.15±2.89) N·cm, respectively.There were no statistically significant differences (P>0.05). The flute of 6.0 mm mini-screws had no statistically significant difference in both insertion and removal torque values and increased to (30.13±1.97) N·cm and (18.65±1.10) N·cm (P>0.05). In experiments with 3.3 mm mini-screws, the insertion and removal torque values decreased to (20.99±3.94) N·cm and (11.32±2.03) N·cm, respectively, showing a statistically significant decrease only in the insertion torque values (P<0.05). The insertion and removal torque values of the mini-screw were not significantly increased even when the screw length was doubled, and the flute formation effect was different with the screw length.

Vaccination has been recently attracted as one of the most successful medical treatments of the prevalence of many infectious diseases. Mucosal vaccination has been interested in many researchers because mucosal immune responses play part in the first line of defense against pathogens. However, mucosal vaccination should find out an efficient antigen delivery system because the antigen should be protected from degradation and clearance, it should be targeted to mucosal sites, and it should stimulate mucosal and systemic immunity. Accordingly, mucoadhesive polymeric particles among the polymeric particles have gained much attention because they can protect the antigen from degradation, prolong the residence time of the antigen at the target site, and control the release of the loaded vaccine, and results in induction of mucosal and systemic immune responses. In this review, we discuss advances in the development of several kinds of mucoadhesive polymeric particles for mucosal vaccine delivery.

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a widely used method for providing nutritional support for patients who require prolonged tubal feeding. As survival times of PEG inserted patients increase, PEG related complications are also increasing. For this reason, we decided to review complications related to PEG. MATERIALS AND METHODS: A retrospective review of medical records was conducted for patients who received PEG placement between January 2004 and March 2013 in our hospital. Of the total 331 cases of PEG placement, 131 cases of PEG exchanges were excluded and a total of 200 cases were included in our review. We reviewed the baseline characteristics of all PEG inserted patients and complications related to PEG insertion. RESULTS: Complications related to PEG developed in 45 of 200 patients (22.5%). Peristomal infection occurred in 22 patients (11.0%) and buried bumper syndrome occurred in 10 patients (5.0%). Other complications that occurred in 13 patients were hemorrhage (3.0%), leakage (1.0%), aspiration pneumonia (1.0%), ileus (0.5%), necrotizing fasciitis (0.5%) and gastro-colo-cutaneous fistula (0.5%). The characteristics according to age, gender, procedure place and underlying disease were not different between the complication group and non complication group. The onset time to complication was significantly different between the buried bumper syndrome group and the other complication groups (P=0.035). CONCLUSIONS: Peristomal infection was the most common complication of PEG in our hospital. Late peristomal infection and buried bumper syndrome occurred more often than previous studies. Buried bumper syndrome was more likely to occur in later time compared with the other complications.

We report a case of acute upper limb ischemia suspected to have originated from methicillin-resistant Staphylococcus epidermidis native valve endocarditis in a 57-year-old man who had complained of sudden-onset fever and pain in the right hand. 3D computed tomography of the right upper extremity detected a thrombus occluding the brachial artery. Echocardiography showed a large vegetation on the aortic valve. Thus, we suspected, clinically, brachial artery occlusion by septic emboli originating from a large vegetation of the aortic valve. The patient was treated with intravenous antibiotics for the suspected methicillin-resistant Staphylococcus epidermidis-native valve endocarditis with a combination of percutaneous aspiration thromboembolectomy and selective intra-arterial thrombolysis for acute thromboembolic occlusion in the right upper limb. The large vegetation of the aortic valve resolved without surgery and aortic regurgitation improved. The patient recovered uneventfully with no complications, including septic embolism, over the following 11 months.
