  • Facial asymmetry is not an uncommon occurrence in day to day dental practice. It can be caused by various etiologic factors ranging from facial trauma to serious hereditary conditions. Here, we report a rare case of non-syndromic facial asymmetry in a young female, who was born with this condition but was not aware of the progression of asymmetry. No relevant family history was recognized. She was also deficient in both deciduous and permanent teeth in the corresponding region of maxilla. Hence, the cause of this asymmetry was believed to be a segmental odontomaxillary hypoplasia of left maxilla accompanied by agenesis of left maxillary premolars and molars and disuse atrophy of corresponding facial musculature. This report briefly discussed the comparative features of segmental odontomaxillary hypoplasia, hemimaxillofacial dysplasia, and segmental odontomaxillary dysplasia and justified the differences between segmental odontomaxillary hypoplasia and the other two conditions.

  • The graft infection within the abdomen is a notorious condition, which usually develops serious complications of anastomotic rupture or distal embolism that ended in death. There has been many controversies in the treatment of an aortobiiliac graft infection and varying results have been reported. The authors treated a case of aortobiiliac graft infection after abdominal aortic aneurysm surgery. The operation was performed with re-aortobiiliac bypass using bilateral superficial femoral veins. The result was successful.

  • A characteristic imaging finding in cases of methanol intoxication is putaminal necrosis, but its presence is usually not suspected due to its rarity. Methanol intoxication generally produces serious neurological symptoms that include visual disturbances and diminished consciousness, characteristically with metabolic acidosis. We reported the case of a 59-year-old man who was admitted to the hospital with diminished consciousness. Acute methanol intoxication was determined as the cause. Laboratory tests revealed high anion gap metabolic acidosis. Diffusion-weighted MRI indicated diffuse symmetric diffusion restriction lesions in the subcortical white matter of both cerebral hemispheres.

  • Electrostatic discharge(ESD) phenomenon is a serious reliability concern. It causes approximately most of all field failures of IC. To quality the ESD immunity of IC product, there are some test methods and standards developed. ESD events have been classified into 3 models, which are HBM, MM and CDM. All the test methods are designed to evaluate the ESD immunity of IC products. This study provides an overview among ESD test methods on ICs and an efficient ESD stress method. We have estimated on all pin combination about the positive and negative ESD stress. We make out the weakest stress mode. This mode called a worst-case mode. We proposed that positive supply voltage pin and I/O pin combination is efficient because it is a worst-case mode.

  • Dental mercury was injected accidentally to left upper buccal mucosa of a 16-year-old girl by charlatan in order to anesthetize a tooth for extraction; thereafter,injected elemental mercury was almost removed by drug adimnistration and surgical operations.One year have passed, still, there are many scaffered small radiopaque white globular cimages in dental, maxillo-facial, and chest radiographs. Redish swollen gingiva and mobility of left upper central incisor which is adjacent to mercury injection site are oral manifestations in this mercury poisoning case. Recently, the patient complains of metallic taste, gastric discomfort and abdominal pain which are thought to be symptoms of mercury poisoning, but there seems to be no serious sequelae now.

  • Intestinal parasitic infections remain a serious public health problem globally and have usually been associated with human malnutrition. This study was performed to observe the present status of intestinal helminthes infections among the primary school children in Iksan, Korea, during the period from June to August, 2006. A total of 974 fecal samples (male 479, female 495) were collected and examined by formalin-ether sedimentation technique for intestinal helminthes eggs. Of the 974 samples examined, 2 (0.2%) were egg positive for intestinal helminthes, and only eggs of Clonorchis sinensis were observed in the 2 cases. These C. sinensis egg were found in grade 5 (male, 1 case) and grade 6 (female, 1 case), respectively. The egg positive rate of male and female were 0.2%, respectively. Through this survey, I found that the C. sinensis infection is prevalent among primary school children in Iksan, Jeonbuk, and a continuous health education for school children is recommended to prevent the potential infection of C. sinensis.

  • In the treatment of the acute respiratory failure, ventilatory support with endotracheal intubation or tracheostomy is a life saving procedure in many cases but the development of postintubation tracheal stenosis is a very serious complication. Recently we have experienced one case of postintubation tracheal stenosis which occurred in the region of cuff site. Preoperative tracheogram showed a concentric stricture 3.0 cm in length located 4.0 cm proximal to the carina. Under the general anesthesia, the stenotic segment was resected and end-to-end anastomosis was performed successfully through the right posterolateral thoractomy. Her postoperative course was uneventful and the patient has remained well till now.

  • Pulmonary embolism (PE) is a serious complication that can occur after orthopedic surgery. Most instances of PE in the orthopedic field have occurred after hip or knee arthroplasties or after fracture surgeries. The occurrence of PE related to arthroscopic shoulder surgery is very rare. We report a case of PE that developed after arthroscopic rotator cuff repair, in which the patient did not show preoperatively any remarkable risk factors for PE. We also review the current literature related to this topic.

  • Angina bullosa hemorrhagica (ABH) is a rare oral mucosal disorder characterized by blood blisters which is not related to hematologic or immunopathologic abnormalities. ABH is most common in middle-aged and elderly people and associated with local trauma, diabetes and long-term use of inhaled steroids. Diagnosis is generally based on reviewing history and clinical presentation and it is important to distinguish it from other serious disorders. Usually, ABH is benign condition which requires no treatment. We present a case of 81-year-old female with ABH.

  • This paper is results of case study on characteristics of debris flow occurred at Jecheon during a heavy rainfall in 2009. The site studied is the mountain area located at Palsong-ri Bongyang-op in Jecheon-si where serious damages due to debris flow were occurred by heavy rainfall during July 7 to July 16 in 2009. Intensity and duration of rainfall causing debris flow were analyzed on the basis of AWS data. Characteristics of debris flow such as initiation, transportation and deposition were investigated through field reconnaissance. The geological and topographical characteristics of slope where debris flow was triggered were figured out and characteristics of erosion on the bottom and sides of valley during transportation of debris flow were also investigated. The slope and boundary of valley where the debris flow started to be deposited were studied.
