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 AND OBJECTIVES: Radiofrequency (RF) catheter ablation of the pulmonary vein (PV) can treat drug refractory focal atrial fibrillation (AF). However, high RF energy (RFE) can cause severe PV damage, and the lower limits of effective RFE in PV have not yet been elucidated. This study attempts to evaluate the changes of PV structure after various modes of RFE delivery. MATERIALS AND METHODS: Right heart and transseptal catheterization were performed in 5 anesthetized mongrel dogs. RFE was delivered at the right superior pulmonary vein (RSPV) with 50 watts and 70degreesC and at the left superior pulmonary vein (LSPV) with 20 watts and 50degreesC. After the procedures, the endocardiums of the left atrium and both superior PVs were examined. RESULTS: Total applied RFE in both PVs was 14.2+/-.2 vs. 13.5+/-.6 watts, 46.6+/-.1 vs. 64.5+/-.2degreesC (p<0.05), in LSPV vs. RSPV, respectively. Follow up pulmonary venograms showed that total occlusions of PV branches and severe stenosis of proximal PV (>70% luminal narrowing) developed in 4 dogs with high RFE. Mild stenosis (<50% luminal narrowing) of PV developed in 1 dog with low RFE. Histological examination of the 5 dogs revealed coagulation necrosis over the whole PV layer, including the adventitia and some portion of the myocardial sleeve, and severe hemorrhage and destruction of PVs from high energy treatment, in contrast to intimal damage and swelling of subintimal PV layers in low energy treatment. CONCLUSION: High RF current may result in severe damage of pulmonary veins and sub-structures whereas low RF current may cause suboptimal pulmonary vein damage such as intimal only damage.

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.

Paradoxical embolism refers to the embolic entry of a venous thrombus into the systemic circulation through a right-to-left shunt. Impending paradoxical embolism, in which a venous thrombus extends from the right atrium through a patent foramen ovale (PFO) into the left atrium, is usually diagnosed with echocardiography. The most common cause of paradoxical embolism through a PFO is the acute pulmonary embolism. We report a case of a 78-year-old woman with acute pulmonary embolism, complicated by impending paradoxical embolism.

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.
