  • Paraneoplastic neurologic syndrome is a group of assorted disorders resulting from damage to the nervous system in cancer, remote from primary site, and not related to metastasis, infection, or metabolic disorder associated with cancer. Patient with small cell lung cancer sometimes shows various neurological syndromes, but patient with non-small cell lung cancer rarely shows neurologic syndromes and few antineuronal antibodies have been found. Here, we report a case of 53-year-old male patient who developed ptosis and extraocular muscular limitation of left eye due to third and forth cranial nerve palsy in non-small cell lung cancer without brain metastasis. These neurologic symptoms improved after lobectomy without any other treatment immunotherapy.

  • Background and Objectives Idiopathic unilateral vocal fold paralysis (IVFP) is believed to be due to inflammation and edema of the recurrent laryngeal nerve caused by viral diseases such as upper respiratory tract infections. Corticosteroid has a potent anti-inflammatory action which should minimize nerve damage. The purpose of this study was to investigate the effect of oral steroid therapy on IVFP. Materials and Method Study was performed for the IVFP patient from January 2012 to August 2017. Patient's dermography, direction and location of paralyzed vocal cords, history of hypertension, diabetes, cerebrovascular disease, and other underlying disease, smoking history, alcohol consumption and upper respiratory tract infection, and symptoms were investigated. Treatment was divided into three groups: the observation group, low-dose group, and high-dose group, and the recovery rate and time of vocal cord paralysis were analyzed in each group. Results Thirty-seven patients were enrolled in this study. There was no relationship between oral steroid use, dosage and recovery of vocal cord paralysis. Oral steroids showed a rapid recovery of vocal cord paralysis, but there was no statistically significant difference in the time of recovery of vocal palsy with or without steroids (p=0.673). In addition, there was no statistically significant difference in recovery rate between the period to start of treatment, presence of diabetes mellitus, and treatment modality, but the recovery rate was high in the group with upper respiratory tract infection history (p=0.041). Conclusion In IVFP, oral steroid therapy has no significant difference in time and extent of recovery compared to the case of spontaneous recovery.

  • Purpose: Recently medical dispute about plastic surgery is increasing rapidly as result of growing surgery itself due to high interest in appearance and advertisement of plastic surgery. So we want to find a way to prevent similar medical accident by making better solution of plastic surgery through case analysis of medical dispute. Method: 161 cases about plastic surgery asked for aid at Korea Consumer Agency and 41 cases judged at the court was surveyed and gender, location and kind of hospital, goal and kind of operation, making operation agreement or not, kind of damage, result of process, result of lawsuit was studied from 2004.1.1. to 2006.12.31. Result: Medical doctor have to explain about symptoms of disease, method of treatment, possibility of complication, prognosis to patients before therapy so they can make decision if they take operation by doctor or not. On this survey, among the patients who underwent re - operation or had complication, 88.1%(96 from 109 cases) of them didn't get enough explanation about possibility of complication before surgery They brought lawsuit insisting they would not undergo operation if they got enough explanation about possibility of complication and result of operation before surgery. Conclusion: It is advisable that doctor must observe the duty of explanation before surgery and respect the right to decide of patient, make operation agreement and put down concrete progress note and store the pre and post operative photo to avoid medical accident. It is also needed to have guideline of therapy, Code of ethics, organization which deals with medical dispute, reconsideration of law to control that.

  • Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

  • The heterodimeric amino acid transporter family is a subfamily of SLC7 solute transporter family which includes 14-transmembrane cationic amino acid transporters and 12-transmembrane heterodimeric amino acid transporters. The members of heterodimeric amino acid transporter family are linked via a disulfide bond to single membrane spanning glycoproteins such as 4F2hc (4F2 heavy chain) and rBAT $(related\;to\;b^0,\;^+-amino\;acid\;transporter)$. Six members are associated with 4F2hc and one is linked to rBAT. Two additional members were identified as ones associated with unknown heavy chains. The members of heterodimeric amino acid transporter family exhibit diverse substrate selectivity and are expressed in variety of tissues. They play variety of physiological roles including epithelial transport of amino acids as well as the roles to provide cells in general with amino acids for cellular nutrition. The dysfunction or hyperfunction of the members of the heterodimeric amino acid transporter family are involved in some diseases and pathologic conditions. The genetic defects of the renal and intestinal transporters $b^{0,+}AT/BAT1\;(b^{0,+}-type\;amino\;acid\;transporter/b^{0,+}-type\;amino\;acid\;transporter\;1)$ and $y^+LAT1\;(y^+L-type\;amino\;acid\;transporter\;1)$ result in the amino aciduria with sever clinical symptoms such as cystinuria and lysin uric protein intolerance, respectively. LAT1 is proposed to be involved in the progression of malignant tumor. xCT (x-C-type transporter) functions to protect cells against oxidative stress, while its over-function may be damaging neurons leading to the exacerbation of brain damage after brain ischemia. Because of broad substrate selectivity, system L transporters such as LAT1 transport amino acid-related compounds including L-Dopa and function as a drug transporter. System L also interacts with some environmental toxins with amino acid-related structure such as cysteine-conjugated methylmercury. Therefore, these transporter would be candidates for drug targets based on new therapeutic strategies.

  • Iron deficiency is a severe nutritional problem in the world. Coffee intake of the people is increasing every year and it can increase the loss of several essential body minerals including iron. Either iron deficiency or coffee intake may increase the oxidative stress of the body. However, the effect of iron deficiency and/or coffee intake on peroxidation have not been studied much. Therefore, the aim of this study was to investigate the effect of coffee intake on oxidative stress and antioxidative enzyme activities of iron-deficient rats. Forty-eight male rats of Sprague-Dawley strain were divided into two groups by dietary iron levels. Iron deficient group were fed 5 ppm iron diet and iron-sufficient group were fed 50 ppm iron diet. Each iron group were divided into three sub-groups by coffee levels (0%, 1%, 4%) included in the experimental diet. The experimental diets were fed for 4 weeks. The hemoglobin level was significantly low in iron deficient group and the level was exacerbated by high coffee intake. The malondialdehyde concentration of the plasma and liver were not affected by iron or coffee level in this study. However, plasma aspartate aminotransferase and alanine aminotransferase, the indicator of the liver damage, were increased by high coffee intake. The erythrocyte and liver superoxide dismutase (SOD) activities were elevated in iron deficient groups. Coffee intake increased erythrocyte SOD activity in iron sufficient groups. Glutathione peroxidase and catalase activities were not influenced much by either iron or coffee intake. In conclusion, high coffee intake in iron deficiency may not only increase the anemia symptoms, but also may increase the oxidative stress of the body.(Korean J Nutrition 35(9) : 919~925, 2002)
