Therapeutic comparison of Surgery combined with chemotherapy and chemotherapy alone for Primary Gastrointestinal Lymphoma: A single center study / 고신대학교의과대학학술지

OBJECTIVES: There is still no consensus on the optimal treatment for primary gastrointestinal lymphoma (PGIL). The aim of this study was to compare surgery combined with chemotherapy and chemotherapy alone in PGIL. METHODS: We retrospectively reviewed and analyzed the treatment outcomes of 107 patients with primary gastrointestinal lymphoma diagnosed between March 1999 and December 2009 at Kosin University Gospel Hospital. Patients were divided into two groups: 35 patients who underwent surgery combined with chemotherapy (group A) and 72 patients who were treated with chemotherapy alone (group B). And we analyzed prognostic factors associated with short survival. RESULTS: The 5-year progression free survival rates (PFS) of group A and B were 86.7% and 66.1%, respectively (P = 0.037), while the 5-year overall survival rates (OS) were 86.8% and 68.4%, respectively (P = 0.129). In multivariate analysis, Both PFS and OS were not changed by treatment strategies (surgery combined with chemotherapy or chemotherapy only). The international prognostic index (IPI) was the only independent predictive factor for PFS. CONCLUSIONS: In our study, surgery combined with chemotherapy and chemotherapy only make no difference of survival rate. And further randomized prospective studies are needed to confirm a treatment strategies at improving survival outcomes in PGIL patients.

Cardiac Involvement in Hypereosinophilia Associated with Toxocariasis

Cardiac involvement in hypereosinophilia is rare; when present, it manifests as ventricular thickening, usually with fibrous tissue and mural thrombosis. We present a case of a 57-year-old man with an abnormal right ventricular apex with eosinophilia, which was caused by Toxocara canis infection.

Delayed onset urticaria and angioedema caused by components of itraconazole solution

Itraconazole, new triazole agent with a broader antifungal spectrum than fluconazole, has been prescribed widely in the treatment and prophylaxis for fungal infection. Itaconazole has been reported to have gastrointestinal disturbance (4%) and headache (1%) as its most common side-effects. However, allergic reactions caused by this drug are rare. A 53-year-old woman with myelodysplastic syndrome received prophylactic antibiotic therapy including itraconazole solution before chemotherapy. She complained of hive on the face with angioedema at 6 hours after taking them. The symptoms were more aggravated on the next day and reversed by stopping itraconazole solution and injection of antihistamine and steroids. Skin prick tests with itraconazole solution, itraconazole tablet, and ketoconazole showed all the negative responses. The oral challenge test with itraconazole solution was performed and resulted in urticaria and angioedema 6 hours later. Next, the oral challenge test with intraconazole tablet was performed and showed negative response. The patient was finally diagnosed as adverse reaction by additives contained intraconazole solution. We report, a case of delayed onset urticaria and angioedema caused by components of itraconazole solution.

Impact of Pheochromocytoma on Left Ventricular Hypertrophy and QTc Prolongation: Comparison with Takotsubo Cardiomyopathy

BACKGROUND AND OBJECTIVES: Excessive catecholamine causes the alteration of cardiac structure and function. This study evaluated if there is any difference in left ventricular hypertrophy (LVH) and QTc prolongation in conditions with pheochromocytoma and Takotsubo cardiomyopathy (TC). SUBJECTS AND METHODS: We reviewed the medical records of 20 pheochromocytoma patients for cardiovascular events prior to diagnosis. The patient's clinical history and electrocardiographic and echocardiographic findings were compared to those of 20 patients diagnosed with TC. RESULTS: Left ventricular (LV) mass index (133.3+/-37.8 vs. 113.3+/-17.3, p=0.031), relative wall thickness (0.55+/-0.15 vs. 0.47+/-0.07, p=032) and elevated blood pressure (BP) were more prominent in pheochromocytoma compared to TC. The mean creatinine kinase-MB elevation, reduced LV systolic function and ST segment changes were more prominent in the TC group compared to the pheochromocytoma groups (all p<0.05). The prevalence of QTc prolongation was high in patients with pheochromocytoma (45%) and TC (55%), and TC male patients appeared to have a more prolonged QTc interval. Urine epinephrine (r=0.844, p=0.004) and norepinephrine level (r=0.782, p=0.013) were significantly correlated with LV mass index, and the predictors for the QTc prolongation were male gender and the presence of LVH. CONCLUSION: A prolonged QTc was prominent in pheochromocytoma and TC regardless of BP and systolic LV function, and LVH was more prominent in pheochromocytoma than TC.
