OBJECTIVES: To report on the skin discoloration experienced by three workers handling 2 , 5 -hexanedione METHODS: Three workers, who showed orange-brown discoloration of the palms during observation under the Kumi occupational disease surveillance system, had their history evaluated and underwent physical examination. A workplace survey was performed by an occupational physician and an industrial hygienist. RESULTS: The three workers were determined to have been experiencing skin discoloration since the introduction of a new cleaning solvent. The new solvent contained 2,5-hexanedione, which is reported in the literature to be possibly capable of causing orangebrown discoloration of the skin. After discontinuation of solvent use, the workers recovered within a week. CONCLUSIONS: These cases demonstrate that 2,5-hexanedione can produce skin pigmentation.

Long QT syndrome is a cardiac disorder of repolarization which is characterized by elctrocardiographic abnormalities including prolonged QT interval, T-wave abnormalities and polymorphic ventricular tachycardia known as Torsades de Pointes. Its clinical manifestation are recurrent syncope, seizure, and sudden death. Recently,we experienced Torsades de Pointes(TdP) by head-up tilt test in 24 year-old female patient presenting recurrent syncope and long QT interval. Beta-blocker and left cervicothoracic sympathetic ganglionectomy were not effictive, then we tried mexiletine. After mexiletine medication, the QT interval was significantly shortened and there was no more syncope.

This study was performed to observe the changes of glucose-related hormones and the morphological change including ultrastructure of the pancreatic islets in the male Otsuka Long-Evans Tokushima Fatty rat. Area under the curve (AUC) of glucose at the 30th (709 +/- 73 mg.h/dL) and at the 40th week (746 +/- 87 mg.h/ dL) of age were significantly higher than that at the 10th week (360 +/- 25 mg.h/ dL). AUC of insulin of the 10th week was 2.4 +/- 0.9 ng.h/mL, increased gradually to 10.8 +/- 8.3 ng.h/mL at the 30th week, and decreased to 1.8 +/- 1.2 ng.h/mL at the 40th week. The size of islet was increased at 20th week of age and the distribution of peripheral alpha cells and central beta cells at the 10th and 20th weeks was changed to a mixed pattern at the 40th week. On electron microscopic examination, beta cells at the 20th week showed many immature secretory granules, increased mitochondria, and hypertrophied Golgi complex and endoplasmic reticulum. At the 40th week, beta cell contained scanty intracellular organelles and secretory granules and apoptosis of acinar cell was observed. In conclusion, as diabetes progressed, increased secretion of insulin was accompanied by increases in size of islets and number of beta-cells in male OLETF rats showing obese type 2 diabetes. However, these compensatory changes could not overcome the requirement of insulin according to the continuous hyperglycemia after development of diabetes.

Arterial bleeding after pancreaticoduodenectomy is a very serious complication with high mortality. Therefore, early diagnosis and treatment is essential. In particular, early detection and immediate embolization can be effectively used for the delayed massive bleeding that occurs from a pseudoaneurysmal rupture. However, sometimes intermittent bleeding or a vessel spasm can cause the bleeding focus to remain unidentified in spite of repeated angiography. We experienced a case of successful embolization with superselection by endoscopic hemoclipping in a patient who underwent pylorus preserving pancreaticoduodenectomy, and the patient's bleeding focus was not found after repeated angiography. Endoscopic hemoclip application can be useful for localizing a pseudoaneurysmal rupture in patients with pancreaticoduodenectomy.

BACKGROUND: Restrictive left ventricular (LV) filling patterns after acute myocardial infarction (AMI) predict poor prognosis. Doppler indexes of LV inflow, especially peak velocity ratio of early versus late diastolic flow (E/A) and deceleration time, can predict heart failure or death. Doppler indexes of pulmonary venous flow are also used to diagnose restrictive LV filling, but their prognostic values after AMI are not known. METHODS: Doppler echocardiographic examination were performed in patients with AMI (n=122) between 7 to 10 days after attack, and followed for 30 months. Death group included 9 deaths (7.4%) during follow-up. 18 age-matched patients (control group) were selected from 70 patients without death, heart failure or readmission. Doppler echocardiographic indexes of peak systolic velocity (SV), peak diastolic velocity (DV), and peak reverse flow velocity associated with atrial contraction (AR) of pulmonary venous flow were measured by transthoracic echocardiography. RESULTS: Death group had lower SV (46.1+/-6.3 vs 57.0+/-14.7 cm/sec; p=0.059) and SV/DV ratio (1.26+/-0.50 vs 1.58+/-0.37; p=0.076). Death group had significantly more patients with SV/DV ratio less than 1.3 (67% vs 17%; p=0.026). AR was significantly different between death and control groups (29.7+/-7.8 vs 24.7+/-6.8 cm/sec; p=0.023). Death group had significantly more patients with AR greater than 25 (78% vs 33%; p=0.046). CONCLUSION: SV/DV ratio and AR of pulmonary venous flow predicted death after AMI.

PURPOSE: To evaluate the effects of autologous tumor vaccine alone or in combination with dendritic cell vaccines, as a method of stimulating antigen-presenting cells in patients with a locoregionally confined renal cell carcinoma (RCC) or metastatic disease. MATERIALS AND METHODS: Twenty-seven patients with RCC pathological stages II to IV were treated with autologous tumor cell vaccine, either with or without dendritic cell vaccine. Interleukin 2 (IL-2) based immunotherapy was also applied to the patients with metastatic disease. Immunomagnetic beads were used to isolate CD14+ monocytes from patient or donor in dendritic cell preparations. IL-4 and granulocyte-macrophage colony stimulating factor (GM-CSF) were used for maturation of dendritic cells. Flow cytometry evaluations were performed for dendritic cell maturation and changes in the immunological profiles following our treatment. RESULTS: Both the isolation of CD14+ monocyte, using Immunomagnetic beads, and the maturation of dendritic cells, using IL-4 and GM-CSF stimulation, were effective. Tumor immunological profiles showed increased CD3 and CD56 populations after treatment. Side effects related with vaccine were minimal and tolerable. Patients were stratified by the purpose for the vaccination; 8 patients for post-nephrectomy adjuvant therapy and 19 for adjuvant immunotherapy of a metastatic disease. All 8 patients in the former showed a disease free state, while only one of the 19 in the latter group remained in complete remission, while 6 showed short-term responses. CONCLISIONS: Autologous RCC vaccine, combined with or without dendritic cell vaccine, might be effective in the suppression of tumor recurrence in locoregionally confined RCC, although a longer follow-up will be required. These vaccines should be further developed to reach their therapeutic purpose in metastatic RCC.

BACKGROUND AND OBJECTIVES: Dual blood supply to the anterior interventricular septum (IVS), derived from the septal branches of the left anterior descending artery (LAD) and the conal branch of the right coronary artery (RCA), may prevent ST segment elevation in lead V1 during an anterior acute myocardial infarction (AMI), and predict a favorable in-hospital clinical course. SUBJECTS AND METHODS: The admission 12-lead electrocardiogram (ECG), and the coronary angiograms performed within 10 days of hospital admission, were evaluated in 67 patients with anterior wall AMI, as defined by a ST segment elevation > or =2mm in at least 2 of the V1 to 4 leads. The patients were divided into two groups according to the magnitude of the ST segment elevation in V1 lead: group 1 (ST <1.5 mm, n=22) and group 2 (ST > or =1.5 mm, n=45). The conal branch types were classified into small (a diameter <0.5 mm), not reaching the IVS, and large (a diameter >0.5 mm), reaching the IVS. RESULTS: A large conal branch was found in 11 patients of each group 50 and 24%, respectively (p=0.04). There was no significant relation between the sites of the LAD lesion, whether proximal or distal to the first septal branch, and the presence of ST segment elevation in lead V1. The serum cardiac enzymes, Killip class and the incidence of in-hospital congestive heart failure, were not significantly different. CONCLUSION: The absence of ST segment elevation in lead V1 during an anterior AMI suggested that the IVS is protected by a large conal branch, in addition to the septal branch of the LAD, but this did not influence the in-hospital clinical course.

PURPOSE: The aim of this study is to investigate the difference between male and female in some clinically meaningful aspects and to prevent intentional poisoning in children and adolescents. METHODS: Retrograde medical records review of patients who visited the emergency department of two secondary hospitals for drug ingestion from March 2010 through March 2013 was performed. Unintentional ingestion or ingestion by others was excluded. RESULTS: A total of 138 cases were reported, male 25.4% (n=35), female 74.6% (n=103). The reason for poisoning was intentional in 132 cases (95.7%) and misuse in six cases (4.3%). In female patients, non-prescription drugs was the most common cause of intentional poisoning (68.9%). Male patients tend to use life substances for intentional poisoning more frequently (20.0%) than female (3.9%). Seven male patients and 12 female patients had previous psychiatric history and 34.3% of male and 41.7% of female were consulted to the psychiatric department. CONCLUSION: Female adolescents are more likely to ingest drugs intentionally for suicide attempt than males of comparable ages. The drugs they ingested were, in many cases, obtained with ease from the drug store nearby and, remarkably, most of the drugs they obtained in that way were acetaminophen-containing. This suggests that some guidelines or control in the pharmacy that restrict children or adolescents from obtaining potentially or possibly life-threatening drugs might be necessary. In addition, education regarding drugs is thought to be necessary in school for teenagers as they tend to misuse them with incorrect acknowledgement.
