QRS voltage and cycle length alternation can be seen during supraventricular re-entrant tachycardias, especially in atrioventricular (AV) re-entrant tachycardia. We present a case of a 20-year-old man, in which AV nodal re-entrant tachycardia (AVNRT) shows alternation of QRS voltage and cycle length, as well as right bundle branch block aberration due to a re-entrant circuit using two distinct, beat-to-beat alternating slow AV nodal pathways antegradely and a single fast pathway retrogradely. Although more than one antegrade slow pathway exists, creation of a single lesion at the right posterior atrial septum using the conventional right-sided approach successfully eliminated AVNRT. 相似文献

Background
Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory disease of the breast. It is related to various etiological factors. The treatment of IGM is challenging as there is a lack of consensus in the literature and treatment options vary widely. Conservative treatment with antibiotics, glucocorticoids and immunosuppressive drugs, and surgery are used in the management of the disease. In this article we report our experience with IGM patients receiving immunosuppressive treatment.Patients and Methods
The medical records of patients with IGM receiving systemic therapy at the Hacettepe University Hospital between October 2007 and May 2010 were reviewed. 15 cases of histopathologically proven IGM were identified. The data was examined for risk factors and success of treatment.Results
14 patients were given prednisolone together with azathioprine, and 1 patient who was pregnant at the time of diagnosis received only prednisolone (30 mg/day). 11 (73%) patients had a complete response to systemic therapy. 2 patients had a relapse, of whom 1 required surgical drainage and 1 was treated with a higher dose of glucocorticoids.Conclusion
Systemic therapy is a safe and effective treatment for IGM. The addition of azathioprine to glucocorticoid therapy permits quick tapering of the steroid doses and increases the treatment success. 相似文献96.

Endobronchial tuberculosis (EBTB) and chylothorax are rare clinical disorders. The concurrence of these two disorders as manifestations of childhood pulmonary tuberculosis has not been reported. We report a 4-month-old boy presenting with chylothorax as the initial presentation of tuberculosis that has been successfully treated with octreotide, antituberculosis drugs and steroid therapy. 相似文献

Congenital nonfamilial supravalvular aortic stenosis (SVAS) is relatively rare, its diffuse type being the least common. We present a 30-year-old woman with diffuse SVAS complicated with left ventricular apical aneurysm. We believe that subtle left ventricular myocardial ischemia or infarction and long-lasting severe pressure overload to the apical chamber caused LV apical aneurysm in our case. Acquired LV apical aneurysm secondary to supravalvular aortic stenosis, in the absence of atherosclerotic coronary artery disease and hypertrophic obstructive cardiomyopathy, has not been described before. 相似文献

Buerger's disease is a recurrent inflammatory, nonatherosclerotic vasoocclusive disease, which typically affects small and medium-sized arteries, veins, and nerves of the upper and lower extremities. Systemic manifestations involving cerebral, mesenteric, and coronary arteries are exceptional. Moreover, multisystem involvement of 2 or more organs is extremely rare. The authors present a case of Buerger's disease in a patient who subsequently developed cerebral and bowel infarcts as well as cavernomatous transformation of the portal vein. Therefore, Buerger's disease, although rare, does have a chronic aggressive nature in some patients. 相似文献

Abstract: Aim: The aim of this study is to describe a unique 7th day syndrome (7DS), quite different from other causes of post‐transplantation allograft dysfunction in a group of orthotopic liver transplant (OLT) patients who needed retransplantation. Methods: A retrospective analysis of 594 consecutive OLT over an 8‐year period revealed that 10 patients developed allograft dysfunction approximately 7 days following an initially normal graft function. Results: The features included: (a) severe liver failure; (b) sudden peak of extremely high liver enzymes at approximately day 7; (c) serial liver biopsy findings of central lobular hemorrhage with minimal inflammatory cell infiltrate and (d) an explant with no evidence of vascular thrombosis. The biochemical and morphometric pathological data of these patients were compared with data of patitents who had early acute rejection (AR), hepatic artery thrombosis (HAT), primary non‐function (PNF), severe sepsis and no dysfunction. Lastly, serial liver core biopsies and explants were tested for evidence of apoptosis, which revealed a significantly higher number of apoptotic hepatocytes in 7DS compared to all control groups. Conclusions: Seventh Day Syndrome is a distinct entity associated with early graft dysfunction characterized by a marked apoptosis of hepatocytes. Fas receptor activation or other pathways of program cell death may be implicated in occurrence of 7DS. 相似文献
