2.Medial Lemniscus Tract Lesion After High Voltage Electrical Injury: A Case Report.
Annals of Rehabilitation Medicine 2017;41(2):318-322
We present the case of a 33-year-old man who experienced a 10,000-V electrical shock when working with electrical wiring. He suffered third-degree burns on his scalp at the right occiput (entry wound) and on his left arm (exit would), and a second-degree burn on his left foot (exit wound). He presented with severe spasticity of both lower extremities, motor weakness with a Medical Research Council grade of 3, and sensory impairments below thoracic level 11 that included an inability to sense light touch and defects in proprioception. Initial magnetic resonance imaging (MRI) scans of his spine and brain showed no definite abnormalities. However, tractography obtained by diffusion tensor imaging of the brain showed absence of the right medial lemniscus tract. A cervical MRI scan 1 month later showed spinal cord swelling from cervical 1-5 levels, and signal changes in the lateral and posterior white matter in the axial view. After 6 months of rehabilitation, he recovered almost normal degree of motor function in his lower extremities and disappearance of spasticity. However, since the sensory impairments persisted, especially defects in proprioception, he was unable to walk independently.

BACKGROUND: Herpes simplex virus thymidine kinase (HSVtk) phosphorylates the prodrug ganciclovir to a nucleoside analog that inhibits DNA synthesis, causing cell death. Neighbouring nontransfected cells may be affected through a 'bystander effect', thereby amplifying the antiproliferative actions. This study was carried out to determine whether retrovirus-mediated HSVtk gene therapy could reduce intimal hyperplasia and prevent stenosis following balloon injury of the rat carotid artery. METHODS: A replication-defective recombinant retroviral vector containing HSVtk cDNA (LtkSN) was constructed. Cultured primary rat smooth muscle cells (SMCs) infected with this vector (SMC/LtkSN) were transplanted to the balloon injured rat right carotid artery. One week after transplantation, HSVtk gene therapy group was administered a 2-week treatment of ganciclovir (30 mg/kg/d). Three weeks after balloon injury and SMC/LtkSN transplantation, carotid arteriography was performed and carotid arteries were perfusion-fixed for histologic examination. RESULTS: Carotid arteriographic evaluation comparing with the uninjured left carotid artery showed that the mean luminal diameter of HSVtk gene therapy group (n=5, 85+/-3%) was significantly larger than that of balloon injury only group (n=5, 65+/-5%). The neointimal mass of HSVtk gene therapy group was less than that of balloon injury only group. SMC/LtkSN transplantation without ganciclovir treatment group (n=3) showed asymmetric intimal proliferation probably because of gravitational pooling of seeding. There were inflammatory cell infiltrations at the gravity dependent portion of HSVtk gene therapy group. CONCLUSION: Retrovirus-mediated HSVtk gene therapy following balloon injury of the rat carotid artery reduced neointimal expansion and arteriographic stenosis.

Diurnally fluctuating hereditary progessive dystonia is a rare movement disorder characterized by marked diurnal fluctuation of symptoms and dramatic response to levodopa. We report two advanced female patients of two families who presented with progressive dystonia and gait disturbance. Both patients have a family history and showed excellent response to levodopa.

BACKGROUND: Recently in Korea, the rate of addictive drug abuse is rapidly increasing in men on salary, housewives, and even in adolescents, who have been considered to be free from drugs, which presents a serious problem to the society. Especially, the habituation to gateway drug, such as cigarettes and alcohol, before 15 years old, would lead to the increased possibility of other drug abuse, including illicit drugs. Thereupon in this study, we intended toreview the effect of adolescents smoking an the drug abuse and deviated behaviors. METHODS: On September, 1997, randomly selected were 12 classes, an the basis of 2 classes per grade, from the two schools which was located each in Seoul and Buchean. And survey was dane on 610 students with non non-nominl, self-reported questionnaire. RESULTS: The rate of adolescent smoking was 28.1% in male students and had increasing tendency of "the higher the grades, the higher the smoking rate"(17.0% in the 1st gade, 31.5% in the 2nd grade, 35.9% in the 3rd grade). The smoking rate of female students was 12.3%. From the 2nd grade of middle school to the 2nd grade of high school was the critical period when the smoking habit was initiated in almost 90% of the students. The experiencing rates of drug abuse in studied subjects were as follows : drinking(79.0%), stimulants(4.8%), sedatives(4.1%), hypnotics(3.1%), glue sniffing(1.5%), butane gas(0.7%), marijuana/hemp(0.2%). They were higher in the smoking group than in the nansMoking group, showing statistical significances in most items except hypnotics and marijuana/hemp. Also simihr results were shown in deviated behaviors between the groups. CONCLUSIONS: With the concerted efforts of family, school, society and natian, we as family physicians should make efforts to delay and prevent adolescent's smoking, which is a gateway to drug abuse and deviated behaviors, and to increase people's recognition of health risks caused by smoking, and to provide proper program for adolescents to stop smoking.

In Korean, there has been an increasing concern on rickettsiosis as a possile common cause of unknown febrile illness since Tsutsugamushi fever among koreans was reported first in 1986. We experienced 10 cases of Tsutsugamushi fever ocurring in the Mokpo area during the period of 3 months (Oct, to Dcc.) in 1990, which were diagnosed clinically and serologically by indirect immunofluorescent antibody test. The following results were obtained. The most frequent symptoms were fever (100%), headache (90%), chill (60%), conjunctival injection, and lymphadenopathy. Common laboratory findings were leukopenia (WBC<5000/mm3 30%), elevated ESR (>20mm/hr, 30%), positive CRP (60%), and elevated Alt/AST. Antibody titers against R. tsutsugamushi ranged from 1:80 to 1:1,280, but they showed no antibody reaction to Hantaan virus and leptospira. All patients showed good response to antibiotic therapy with chloramphenicol.

PURPOSE: It may be difficult to differentiate renal cell carcinoma involving collecting system from renal urothelial tumor invading into renal parenchyma. The purpose of this study was to assess the differences of CT findings between two conditions. MATERIALS AND METHODS: CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. RESULTS: Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reniform shape(100%). CONCLUSION: Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities.
