It is not uncommon for idiopathic parkinson's disease (IPD) to occur concurrently with other degenerative dementing disorders such as Alzheimer's disease. However, there has been no report about the comorbidity of IPD and frontotemporal lobar degeneration. We report a 70-year-old man diagnosed with IPD accompanied by progressive non-fluent aphasia (PA). Brain MRI showed left frontal opercular atrophy, and an 18F-FDG PET scan revealed predominant left frontotemporal hypometabolism. It remains unknown whether or not the co-occurrence of IPD and PA was coincidental.

BACKGROUND: Bronchioloalveolar carcinoma (BAC) has been reported to diveres spectrum of chinical presentations and radiologic patterns. The three representative radiologic patterns are followings; 1) a solitary nodule or mass, 2) a localized consolidation, and 3) multicentric or diffuse disease. While, the localized consolidation and solitary nodular patterns has favorable prognosis, the multicentric of diffuse pattern has worse prognosis regardless of treatment BAC presenting as a solitary pulmonary nodule is often misdiagnosed as other benign disease such as tuberculoma. Therefore it is very important to make proper diagnosis of BAC with solitary nodular pattern, since this pattern of BAC is usually curable with a surgical resection. METHODS: We reviewed the clinical and radiologic features of patients with pathologically-proven BAC with solitary nodular pattern from January 1995 to September 1996 at Samsung Medical Center. RESULTS: Total 11 patients were identified. 6 were men and 5 were women. Age ranged from 37 to 69. Median age was 60. Most patients with BAC with solitary nodular pattern were asymptomatic and were detected by incidental radiologic abnormality. The chest radiograph showed poorly defined opacity or nodule and computed tomography showed consolidation, ground glass appearance, internal bubble-like lucencies, air bronchogram, open bronchus sign, spiculated margin or pleural tag in most patients. The initial diagnosis on chest X-ray were pulmonary tuberculosis in 4 patients, benign nodule in 2 patients and malignant nodule in 5 patients. The FDG-positron emission tomogram was performed in eight patients. The FDG-PET revealed suggestive findings of malignancy in only 3 patients. The pathologic diagnosis was obtained by transbronchial lung biopsy in 1 patient, by CT guided percutaneous needle aspiration in 2 patients, and by lung biopsy via video-assited thoracocopy in 8 patients. Lobectomy was performed in all patients and postoperative pathologic staging were T1N0M0 in 8 patients and T2N0M0 in 3 patients. CONCLUSION: Patients of BAC presenting with solitary nodular pattern were most often asymptomatic and incidentally detected by radiologic abnormality. The chest X-ray showed poorly defined nodule or opacity and these findings were often regarded as benign lesion. If poorly nodule or opacity does not disappear on follow up chest X-ray, computed tomography should be performed. If consolidation, ground glass appearance, open bronchus sign, air bronchogram, internal bubble like lucency, pleural tag or spiculated margin are found on computed tomography, further diagnostic procedures, including open thoracotomy, should be performed to exclude the possiblity of BAC with solitary nodular pattern.

We surveyed the generation rate of health statistics by medical records offices of the 78 hospitals and its automation rate using computerized hospital information system. Structured questionnaire was given to one medical record officer of each hospital. Items in the questionnaire was selected from statistics required for hospital service evaluation or OECD health statistics. More than 50% of the medical record office generated questioned health statistics, and most of them was automated. Because many of the medical record offices of the hospitals are producing essential health statistics and automated, there is a possibility that we can collect and use these datas to build up national health database if adequate standardization procedure can be implemented.

Advances for the treatment of childhood cancer in several decades have remarkably improved long-term survival. Anticancer therapy is capable of causing a variety of delayed toxicities including secondary malignant neoplasm. Therefore close follow-up for secondary malignant neoplasm is important for surviving patients from cancer. Renal cell carcinoma is a rare tumor in childhood and has been reported previously to occur after treatment of a few solid tumors, including neuroblastoma. This report represents the first documented case of renal cell carcinoma arising as a secondary malignant neoplasm in a pediatric patient who previously was treated for germ cell tumor.

BACKGROUND: We assessed the association of dipeptidyl peptidase 4 inhibitors (DPP4i) with hospitalization for heart failure (HF) using the Korean Health Insurance claims database. METHODS: We collected data on newly prescribed sitagliptin, vildagliptin, and pioglitazone between January 1, 2009 and December 31, 2012 (mean follow-up of 336.8 days) to 935,519 patients with diabetes (518,614 males and 416,905 females) aged 40 to 79 years (mean age of 59.4 years). RESULTS: During the study, 998 patients were hospitalized for primary HF (115.7 per 100,000 patient-years). The incidence rate of hospitalization for HF was 117.7 per 100,000 per patient-years among patients on pioglitazone, 105.7 for sitagliptin, and 135.8 for vildagliptin. The hospitalization rate for HF was greatest in the first 30 days after starting the medication, which corresponded to a significantly higher incidence at days 0 to 30 compared with days 31 to 360 for all three drugs. The hazard ratios were 1.85 (pioglitazone), 2.00 (sitagliptin), and 1.79 (vildagliptin). The incidence of hospitalization for HF did not differ between the drugs for any time period. CONCLUSION: This study showed an increase in hospitalization for HF in the initial 30 days of the DPP4i and pioglitazone compared with the subsequent follow-up period. However, the differences between the drugs were not significant.

Inflammatory myofibroblastic tumor of the stomach is a rare tumor-like, benign disease with an uncertain pathogenesis. A 15-year-old male presented with epigastric pain. Endoscopic ultrasonography revealed a 2.3 cm sized ovoid intramuscular mass in the lower body of the stomach at the lesser curvature. Histologically, the tumor was composed of smooth muscle actin positive- and vimentin positive spindle cells and there were a large number of lymphocytes, plasma cells and histiocytes in the fibrotic background. The spindle cells were also positive for ALK1, but negative for EBV in situ hybridization.

This study was conducted to compare the severity of cannulation pain in hemodialysis patients after topical application of EMLA cream and local injection of lidocaine and evaluated side effects and problems accompanied by the former. Twenty patients, who were on hemodialysis from September 1 to October 15, 1994 at the Kangnam St. Mary's Hospital, Catholic University Medical College, were divided into two groups of ten. To conduct a cross over study, two groups were placed on four repeated methods with lidocaine followed by four repeated methods with EMLA cream and vice versa, respectively, while the severity of cannulation pain was being measured according to a Visual Analogue Scale with each methods. The results are follows : 1) The scale of pain was recorded as 4.56+/-1.38 and 2.05+/-1.36 points for methods with lidocaine and EMLA cream, respectively, indicating the less severe pain with EMLA cream. 2) Local side effects such as itching(4 cases, 5.0%) and pallor(5 cases, 6.3%) were observed with methods with EMLA cream but disappeared before the completion of hemodialysis. 3) Problems associated with local lidocaine were pain at the injection of anesthetic (27 cases, 16.9%) and fear for needle insertion (6 cases, 3.8%). The most frequent problems with EMLS cream application were an inconvenience in use (11 cases, 6.9%) and tedious long pretreatment time (11 cases, 6.9%), those associated with inconvenience in cream applying procedures. 4) Twelve out of twenty patients(60.0%) responded with yes to a continued use of EMLA cream in spite of problems with cream application and economical difficulties in purchasing. These results indicate that 5% EMLA cream used as a local anesthetic in hemodialysis significantly reduces cannulation pain and lacks side effects, thus serving as a suitable method for the alleviation of cannulation pain and inconvenience in hemodialysis and the relief of psychological stress of nurses.

BACKGROUND AND PURPOSE: To analyze 18F-THK5351 positron emission tomography (PET) scans of patients with clinically diagnosed nonfluent/agrammatic variant primary progressive aphasia (navPPA). METHODS: Thirty-one participants, including those with Alzheimer's disease (AD, n=13), navPPA (n=3), and those with normal control (NC, n=15) who completed 3 Tesla magnetic resonance imaging, 18F-THK5351 PET scans, and detailed neuropsychological tests, were included. Voxel-based and region of interest (ROI)-based analyses were performed to evaluate retention of 18F-THK5351 in navPPA patients. RESULTS: In ROI-based analysis, patients with navPPA had higher levels of THK retention in the Broca's area, bilateral inferior frontal lobes, bilateral precentral gyri, and bilateral basal ganglia. Patients with navPPA showed higher levels of THK retention in bilateral frontal lobes (mainly left side) compared than NC in voxel-wise analysis. CONCLUSIONS: In our study, THK retention in navPPA patients was mainly distributed at the frontal region which was well correlated with functional-radiological distribution of navPPA. Our results suggest that tau PET imaging could be a supportive tool for diagnosis of navPPA in combination with a clinical history.
