The most frequently reported neurological complication of a wasp sting is ischemic stroke. We treated a patient with wasp sting with unusual complications. A 52-year-old man was hospitalized for anaphylactic shock after multiple wasp stings. Although the patient recovered consciousness after 2 days, he had global aphasia and right hemiparesis. Brain magnetic resonance imaging and angiography revealed high-intensity signals in the left basal ganglia and cerebral cortex and stenosis of the left middle cerebral artery. After 2 days, the middle cerebral artery stenosis improved. After 5 days, diffusion-weighted imaging showed an enlarged lesion in the left frontal cortex. The infarct in this case was due to a predominantly unilateral vasoconstrictive hypoxic brain injury from wasp stings.

The growth changes in position of upper and lower jaws, incisal inclination in relation to anterior cranial base have been described. Twenty five males was studied quantitavely by means of serial cephalometric reontgenogram from seven to thirteen years of age. The findings seem to warrant the following conclusions: 1. Growth change in anteropaterior of upper and lower jaws to the anterior cranial base showed very littel change before eleven years of age but axial inclination of incisal teeth tended to become labiaization in relation to the anterior cranial base. 2. After eleven years of age, there wasn¥t nearly labialization of incisal teeth but jaw prognathism occurred a little in relation to the anterior cranial base.

Background & Objective: The number of ischemic stroke is increasing steadily. The recent stroke prevention strategies have targeted risk factors for preventing ischemic stroke. Community-based data that quantify the prevalence of these risk factors are needed to develop effective stroke prevention strategies. This study was performed aiming to establish customized prevention strategies by investigating vascular risk factors of ischemic stroke among the healthy adults in an urban population in Korea. Methods: The Prevention of Stroke and Dementia (PRESENT) survey collected data associated with stroke risk factors between 2007 and 2009 in Ansan city, Korea. Of 46,537 people, 2,843 were selected by random sampling, and final population included 358 men and 422 women over 50 years old. We checked modifiable risk factors, such as hypertension, diabetes mellitus, smoking, hyperlipidemia, atrial fibrillation, cardiovascular disease, obesity, and physical inactivity. Results: The mean age of study subjects was 60.1±8.2 years; 55.5% had hypertension, 18.6% had diabetes mellitus, 17.7% were current smoker, 44.9% had hyperlipidemia, 1.7% had atrial fibrillation, and 4.5% had cardiovascular disease. Men had more risk factors for stroke, and higher rates of diabetes mellitus and current smoking. However, women had higher cholesterol and obesity rates and lower physical activity. The proportion of individuals with >1 risk factor for stroke increased with age. Hypertension, diabetes mellitus, and cardiovascular diseases also increased with age, but low-density lipoprotein levels and current smoking decreased. Conclusions: This study provides valuable information to develop customized strategic policies for primary and secondary stroke prevention.

We performed dual color fluorescence in situ hybridization (FISH) for the bcr/abl fusion in CML using the peripheral blood smears without destruction of cell morphology to determine the bcr/abl fusion. Two patients of CML, one patient in accelerated phase and one patient in chronic phase, were selected. The blood smears were fixed in absolute methanol. FISH was performed with the Mbcr/abl translocation DNA probe mixture and the slides were stained with Wright's stain after FISH. The blood smears of both cases revealed distinct signals without destruction of cellular morphology. The normoblasts and lymphocytes revealed beautiful fused bcr/abl signals as well as granulocytes in both cases. The results provide a novel finding that the normoblasts and lymphocytes in CML are also neoplastic clonal cells which has not been demonstrated with a single-cell approach before.

PURPOSE: Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament(ACL) injury in MR image. MATERIAL AND METHODS: The knee MR images of 47 patients with ACL injury(complete; 24, partial; 23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. RESULTS: The means( +/- 2standard errors) of anterior translocation were different significantly in statistical analysis(p<0.001, student t-test) between injury group(7.51 +/- 1.16mm) and normal group(-0.56 +/- 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically b. etween injury group(0.23 +/- 0.02) and normal group(0.17 +/- 0.01)(p<0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligament injury(28%), one PCL injury (2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients {43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spine in four patients(9%). CONCLUSION: The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injury on Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

The distance fmm skin to the lumber epidural space was measured in 60 male patients receiving epidural analgesia. The mean distance was found to be 4.45cm. The epidural depths were identified most frequently at 4.0 to 4.5cm deep and over 90% of total cases were less than 5.5cm deep. The epidural depths had correlations with weight and PI(P < 0.001), but not correlated with height.
