PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

Thirty-year old female developed limited range of motion (ROM) of both ankles after radiofrequency muscle reduction procedure for one month prior to her visit. Dorsiflexion of both ankles was severely limited to zero degree. Plantar flexion of both ankles was limited to 20 degree on the right and 15 degree on the left. The electrodiagnostic study and MRI showed normal nerve conduction study and inflammatory change of both gastrocnemius and soleus muscles. She received ROM and stretching exercise for 1 hour per day and twice per week for 4 weeks as an outpatient with continuous home programming. After 2 weeks of treatment, ROM improved to 20 degree plantar flexion and to 20 degree dorsiflexion on the right ankle and to 20 degree plantar flexion to 10 degree dorsiflexion on the left ankle. This is a case of severe muscles contracture after radiofrequency procedure reversible after intensive strengthening exercise.

PURPOSE: The number of patients waiting for kidney transplantation is incessantly increasing, but the number of cadaveric kidney transplantations or ABO-compatible donors is so insufficient that ABO-incompatible kidney transplantation is being performed as an alternative. There are overseas studies and research showing that the 5-year survival rate and 5-year graft survival rate of ABO-incompatible kidney transplantation are not much different from those of ABO-compatible kidney transplantation. However, domestic research on the subject is rare. Therefore, we report the results of 22 ABO-incompatible kidney transplantation cases performed in our hospital. MATERIALS AND METHODS: This research was from 22 patients in our hospital who underwent ABO-incompatible kidney transplantation from 15 February 2007 to 20 May 2010. RESULTS: As yet, there have been no donor graft losses and no deaths after transplantation. The results of the two groups were analyzed by analysis of covariance of the creatinine value of the recipients at 6 months after the operation, corrected for the preoperative value in order to statistically identify whether there were differences in renal function after the operation between ABO-compatible and ABO-incompatible kidney transplantation. The results of the analysis of covariance showed no statistical difference in renal function after the operation between the two groups. CONCLUSIONS: Even though there were not many cases, our initial results for ABO-incompatible kidney transplantation were positive. Considering the increasing number of patients waiting for kidney transplantation, longer-term domestic research studies of ABO-incompatible kidney transplantation are necessary.

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.

Objectives: ：The authors examined the association of sleep quality and metabolic syndrome (MetS) in schizophrenic patients using actigraphy. Methods: ：A total of 101 schizophrenic patients were included in this study. Fifty-four (53.4%) patients met the criteria of MetS. Self-assessment of subjective sleep quality, daytime sleepiness, physical activities were measured using Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and International Physical Activity Questionnaire (IPAQ), respectively. Objective sleep quality and physical activity were measured by Actigraph (ActiGraph wGT3X-BT). Results: ：Total time in bed (TIB) (p=0.032), sleep latency (SL) (p=0.001), wake after sleep onset (WASO) (p<0.001) and average awakening (p=0.015) were significantly longer in patients with MetS than those of non-MetS. Results of multiple logistic regression showed that long sleep latency (OR 7.876, 95% CI 1.519, p=0.014) and low sleep efficiency (OR 9.902, 95% CI 1.111, p=0.040) were high risk factors for MetS. Conclusion ：This was the first study to find the correlations of sleep quality and MetS in schizophrenic patients by objective sleep measurements. Although long sleep latency and low sleep efficiency were associated with MetS in patients with schizophrenia, more extensive and complicated designed studies may be needed to the association of MetS and sleep problems in schizophrenic patients.

Metastases to the thyroid gland are not frequently observed in clinical practice, although an overall incidence of secondary thyroid malignant tumors has been reported to range from 1.25% to 24% in autopsy series. Generally, patients with metastatic thyroid cancer present with euthyroidism and they do not develop thyroid dysfunction. Thyroid dysfunctions, including hypothyroidism and hyperthyroidism, rarely occur in patients with metastatic thyroid cancer. We describe here a case of hypothyroidism induced by thyroid metastasis from cancer of an unknown primary site in a 53-year-old man and another case of thyrotoxicosis induced by thyroid metastasis from lung cancer in a 65-year-old man.

BACKGROUND: Whether thyroid lobectomy alone is a sufficient treatment for papillary thyroid microcarcinoma (PTMC) remains controversial. The aim of this study is to evaluate the predictive factors for incidental contralateral carcinoma in patients confirmed of unilateral PTMC preoperatively. METHODS: Between January 2007 and December 2009, 393 patients underwent thyroid surgery for unifocal and unilateral PTMC preoperatively at Pusan National University Hospital. A total thyroidectomy with central neck dissection was routinely performed for these patients during this study period. RESULTS: Among the 393 cases in the cohort, 77 patients (19.6%) had incidental PTMC in the contralateral lobe. In patients with incidental contralateral carcinoma, there was higher prevalence in extrathyroid extension, occult ipsilateral carcinoma, pathologic Hashimoto's thyroiditis, and central lymph node metastasis compared to those without contralateral carcinoma. The mean tumor size also increased in patients with contralateral carcinoma. Multivariate logistic regression showed that extrathyroid extension (P = 0.049), occult ipsilateral carcinoma (P < 0.001), pathologic Hashimoto's thyroiditis (P = 0.038), and central lymph node metastasis (P = 0.002) were predictive factors for incidental contralateral carcinoma. CONCLUSION: In conclusion, multifocality in the ipsilateral lobe, central lymph node metastasis, extrathyroid extension, and Hashimoto's thyroiditis is associated with the presence of contralateral carcinoma. Thus, if these factors are found by preoperative and/or postoperative evaluation, total thyroidectomy or completion thyroidectomy is necessary for the treatment of PTMC.

We present the case of a patient with acromegaly who had pancytopenia with hypopituitarism secondary to the excision of a pituitary macroadenoma and radiation therapy. A 28-year-old man presented with pancytopenia and serum electrolyte abnormalities. He was diagnosed with acromegaly and underwent surgery and gamma-knife radiotherapy for a pituitary macroadenoma at the age of 22 years. A recent brain magnetic resonance imaging showed an empty sella, and the basal hormonal profile demonstrated deficiencies of pituitary hormones except thyrotropin. As presenting pancytopenia, his bone marrow biopsy showed hypocellular marrow. The total number of hemocytes increased after hydrocortisone replacement. Hypopituitarism was a possible cause of pancytopenia, and glucocorticoids had crucial effects on converting pancytopenia to normal in this case.
