To investigate the imbalance of the cytokine production profile of T cells from atopic asthmatics, we measured concentrations of IL-4, IL-5 and IFN-y by ELISA method in the culture supernatants of peripheral blood mononuclear cells(PBMCs) and Derrnato-phagoides pteronyssinus(Der p) J-stimulated PBMCs from Der p-sensitized atopic asthmatics, Der p-sensitized healthy atopits, non-atopic asthmatics and healthy non-atopics. The suppressive effect of IFN-y on cytokine production of Der p J-stimulated PBMCs was also examined. The PBMCs from atopics showed higher IL-4 and IL-5 production in response to PHA +TPA and higher IFN-gamma production in response to Der p Jq compared with non-atopits. The Der p J-stimulated PBMCs from atopics showed a tendency of increased IL-5 production in response to Der p J and higher IL-4 and IL-5 production in response to PHA+TPA compared with non-atopics. IL-5 production of Der p J-stimulated PBMCs from atopics was suppressed by IFN It is suggested that an imbalance in IL-4, IL-5 and IFN-y production is a feature of the atopic state. The TH2 characteristics of allergen-stimulated PBMCs could be regulated by IFN-y.

Thrombolytic therapy is usually reserved for patients with clinically serious or massive pulmonary embolism. In desperated cases, however, pulmonary embolectomy is recommended despite its high mortality rate. We experienced acute respiraory failure after embolectomy performed under cardiopulmonary bypass in patient with chronic massive pulmonary embolism. The patient recovered sucessfully with postoperative management in the intensive care unit.

Mineral trioxide aggregate (MTA) is widely used in endodontic therapy as a pulp-capping material, root or furcal perforation repair material, and for apexification and obturation of the root canal system. The purpose of this study was to formally document cases of MTA application in South Korean children and adolescents. Through this research, the practice of using MTA will be introduced and familiarized to the clinical practitioners. This study involved endodontic treatment using MTA for fractured crowns in 11- and 12-year-old. The children were followed up for 12 months until the pulp vitality was confirmed; in young permanent teeth with immature roots, the pulp is integral to the process of apexogenesis. These observational results regarding the use of MTA as an apexification material in non-vital immature permanent incisors appear to provide promising results in the search for new materials to meet existing endodontic needs.

BACKGROUND: Most surgeons prefer delivering cardioplegia alternatively via the aortic root and coronary sinus in patients undergoing coronary artery bypass graft surgery (CABG). Recently, some surgeons have delivered cardioplegia via the grafted vessel to the obstructed right coronary artery in order to preserve right ventricular function whenever retrograde cardioplegia is delivered. Thus, we have compared the effect on right ventricular preservation between the aforementioned two methods after cardiopulmonary bypass in patients undergoing a right CABG. METHODS: Twenty-eight patients undergoing an elective CABG with significant right coronary artery obstructive disease were allocated into 2 groups. In the alternative cardioplegia delivery group (A-group), cold blood cardioplegia was delivered via the aortic root and coronary sinus alternatively. In the simultaneous cardioplegia delivery group (S-group), cold blood cardioplegia was delivered via the coronary sinus and grafted vessel to the obstructed right coronary artery simultaneously. Hemodynamic measurements were obtained pre-bypass, at pericardial closure and at sternal closure. Data recorded included right ventricular ejection fraction, right ventricular volume index and right and left ventricular hemodynamics. RESULTS: There was no significant difference in the right ventricular ejection fraction between the two groups at pre-bypass, pericardial closure and sternal closure. In both groups, the right ventricular ejection fraction and cardiac index were not decreased, and the left ventricular ejection fraction was higher at pericardial closure than pre-bypass. However, in both groups, there was a decrease in the right andleft ventricular stroke work index and right ventricular stroke volume index at sternal closure. CONCLUSIONS: We have concluded that simultaneous cardioplegia delivery via the coronary sinus and grafted vessel to the obstructed right coronary artery was not superior to the alternative cardioplegia delivery via the aortic root and coronary sinus for preservation of right ventricular function in patients undergoing a right CABG.

PURPOSE: To investigate the clinical characteristics and the risk factors for mechanical ventilator treatment and incidence of complications in children admitted to an intensive care unit (ICU) with detected respiratory viruses. METHODS: Eighty-two patients who were detected respiratory viruses by multiplex real-time polymerase chain reaction from nasopharyngeal aspirates were enrolled among the 123 children admitted to ICU with acute respiratory manifestations during the study period from January 2006 to December 2012. RESULTS: Detection rate of respiratory viruses were 66% and 13 patients (16%) had two viruses isolated. The most common respiratory virus isolated was respiratory syncytial virus (RSV) (35%) followed by rhinovirus (19%), adenovirus (13%), parainfluenza virus (11%), influenza virus (11%), human metapneumovirus (6%), and human coronavirus (5%). Pneumonia (70%) was the most common clinical diagnosis. The mean age of patient with RSV infection was the youngest and with influenza virus infection was the oldest among other viruses infection (mean+/-standard deviation, 5.9+/-10.1 months vs. 51.0+/-26.1 months; P=0.01). Forty Patients (49%) who had the underlying diseases were not associated with incidence of mechanical ventilator treatment and complications. Bacterial coinfection with respiratory virus was the significant risk factor of mechanical ventilator care and incidence of complications (odds ratio [OR], 50.003; 95% confidence interval [CI], 3.955-632.144; P=0.003, and OR, 15,569; 95% CI, 1.803-134.452; P=0.013). CONCLUSION: The significant morbidity of pediatric patient admitted to ICU with respiratory virus infection (RVI) was associated with bacterial coinfection. Furthermore, multicenter study should be performed to investigate the epidemiology of RVI in pediatric patients admitted to ICU in domestic.

Hematological malignancies rarely affect the breast, and the majority of those that do are lymphomas. In this review, we describe the clinical aspects and multimodal imaging findings of breast lymphoma. We also illustrate the key clinical and radiological findings that allow it to be distinguished from various other malignant and benign diseases of the breast. Breast lymphoma manifests as a breast mass, a change in the subcutaneous tissue or the skin, or enlargement of the associated lymph node on radiological examination. Radiological findings associated with other breast malignancies, such as calcifications, spiculations, or architectural distortions are extremely rare. Skin and subcutaneous changes frequently accompany T-cell lymphoma. Multimodal breast imaging characteristics may aid in the diagnosis of breast lymphoma.

The term histiocytic medullary reticulosis first was introduced by Scott and Robb-Smith. It is a clinicopathologic syndrome characterized by wasting, fever, lymphadenopathy, hepatosplenomegaly, pancytopenia, and is often accompanied by jaundice, purpura. Cardinal pathologic feature are systemized proliferation of atypical, neoplastic, erythrophagocytic D. We are here reporting one case which considered compatible for HMR, with a few elementary reviewed literatures.

Although compressed gas (CO2) blowers have been used safely to aid accurate grafting during off-pump coronary bypass surgery, hemodynamic collapse due to gas embolism into the right coronary artery may occur. Supportive measures to facilitate gas clearance by increasing the coronary perfusion pressure have been reported to be successful in restoring hemodynamic stability. However, right ventricular dysfunction and atrioventricular nodal ischemia may hinder effective systemic delivery of the vasoactive medications, even when performing resuscitative measures such as direct cardiac massage. We herein report a case of cardiac arrest that was caused by a right coronary gas embolism and that could not be restored by cardiac resuscitation. When supportive measures fail, direct aortic injection of epinephrine to increase the coronary perfusion pressure can be attempted before initiating cardiopulmonary bypass, and this approach may be life-saving in situations that limit systemic drug delivery from the venous side despite the performance of direct cardiac massage.
