2.  Clinical significance of standardized uptake value and maximum tumor diameter in patients with primary extranodal diffuse large B cell lymphoma 
The Korean Journal of Hematology  2012;47(3):207-212.
Background
Maximum standardized uptake value (SUVmax) and maximum tumor diameter (MTD) have been shown to reflect survival outcome in diffuse large B cell lymphoma (DLBCL). However, applying these values to primary extranodal DLBCL is difficult because they are separate nosological entities with differences in genetic origin. We therefore decided to evaluate whether SUVmax and MTD on 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18-FDG) positron emission tomography (PET) would affect the survival outcome in primary extranodal DLBCL.
Methods
From October 2005 to November 2010, 76 primary extranodal DLBCL patients receiving R-CHOP therapy were analyzed. All patients had undergone an initial 18-FDG PET/CT and conventional computed tomography (CT) of the neck, chest, abdomen, and pelvis for staging. Median follow-up period was 35 months.
Results
The SUVmax and MTD cut-off values were 11.0 and 7.5 cm, respectively. SUVmax≥11.0 predicted a short progression free survival (PFS, P=0.002) and overall survival (OS, P=0.002). MTD≥7.5 cm was associated with poor PFS (P=0.003) and OS (P=0.003). High International Prognostic Index (IPI) was also associated with the survival outcome (PFS, P=0.046; OS, P=0.030). Multivariate analysis revealed that SUVmax≥11.0 (PFS, hazard ratio [HR]=10.813, P=0.024; OS, HR=6.312, P=0.015); MTD≥7.5 cm (PFS, HR=5.631, P=0.008; OS, HR=4.072, P=0.008); and high IPI (PFS, P=0.027; OS, P=0.046) were independent prognostic factors.
Conclusion
It appears that both MTD and SUVmax can be independent prognostic factors in primary extranodal DLBCL.

3.  Thyrotoxic Periodic Paralysis Associated with Transient Thyrotoxicosis Due to Painless Thyroiditis 
Journal of Korean Medical Science  2012;27(7):822-826.
Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. All ethnicities can be affected, but TPP typically presents in men of Asian descent. The most common cause of TPP in thyrotoxicosis is Graves' disease. However, TPP can occur with any form of thyrotoxicosis. Up to our knowledge, very few cases ever reported the relationship between TPP and painless thyroiditis. We herein report a 25-yr-old Korean man who suffered from flaccid paralysis of the lower extremities and numbness of hands. The patient was subsequently diagnosed as having TPP associated with transient thyrotoxicosis due to painless thyroiditis. The paralytic attack did not recur after improving the thyroid function. Therefore, it is necessary that early diagnosis of TPP due to transient thyrotoxicosis is made to administer definite treatment and prevent recurrent paralysis.
