PURPOSE: Scopolamine is a nonselective muscarinic cholinergic receptor antagonist, which induces impairment of learning ability and memory function. Exercise is known to ameliorate brain disturbance induced by brain injuries. In the present study, we investigated the effect of treadmill exercise on short-term memory in relation to acetylcholinesterase (AChE) expression in the hippocampus, using a scopolamine-induced amnesia model in mice. METHODS: To induce amnesia, 1 mg/kg scopolamine hydrobromide was administered intraperitoneally once per day for 14 days. A step-down avoidance test for short-term memory was conducted. AChE histochemistry, immunohistochemistry for collagen IV, and doublecortin were performed. RESULTS: Short-term memory deteriorated in the mice with scopolamine-induced amnesia, concomitant with enhanced AChE expression and suppression of angiogenesis in the hippocampus. Critically, treadmill exercise ameliorated short-term memory impairment, suppressed AChE expression, and enhanced angiogenesis in the mice with scopolamine-induced amnesia. CONCLUSIONS: Overexpression of AChE is implicated in both brain and renal disease. The findings of our study indicate that treadmill exercise may be of therapeutic value in neurodegenerative and renal diseases by suppressing the effects of AChE expression.

Sclerotic fibroma is a rare skin neoplasm that can occur seen sporadically or in association with Cowden's disease. Clinically, it presents as asymptomatic flesh-colored or pinkish slow-growing papules or nodules with a wide anatomical distribution. We report a rare case of pedunculated type of sclerotic fibroma resembling soft fibroma, which has not been reported in Korea.

PURPOSE: Median nerve entrapment syndrome within carpal tunnel is usually called carpal tunnel syndrome and it is the most common form of peripheral nerve entrapment syndrome. Many factors such as diabetes mellitus, hypothyroidism, hormonal replacement theraphy, corticosteroid use, rhematoid arthritis and wrist fractures may cause carpal tunnel syndrome. To the best of our knowledge, this is the first case report of median nerve entrapment syndrome due to adhesion of laceration wound after suicidal attempt. METHODS: A 28-year-old woman presented with a sensory change and thenar hypotrophy on her left hand. On her history, she attempted suicide by slashing her wrist. Initial electromyography (EMG) showed that the nerve conduction velocities of median nerve was delayed. Therefore, we performed surgical procedures. When exploration, Fibrous scar tissue observed around the median nerve but nerve had not been injured. Transcarpal ligament was completely released and adjacent fibrous tissue was removed to decompress the median nerve. RESULTS: The postoperative course was uneventful until the first year. Opposition difficulty and thenar hypotrophy were improved progressively after the surgery. Sensory abnormality was slowly improved over one year. CONCLUSION: We report a case of median nerve entrapment syndrome that was caused by adhesion of laceration wound after suicidal attempt. This is an unusual cause of median nerve entrapment syndrome, the symptoms were relieved after transcarpal ligament release and fibrous scar tissue removal.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and relationship with depression and social disability. METHODS: Study subjects consisted of 35 panic disorder patients diagnosed with the criteria of DSM-IV. Data were collected through Sixteen Personality Factor Questionnaire, Ehwa Diagnostic Test of Defense Mechanism, Beck Depression Inventory and Sheehan Disability Scale. Statistics employed for the analyses were Pearson correlation and independent sample t-test. RESULTS: In personality factors and defense mechanisms, there were no definitely abnormal range of scores. But, among personality factors, tension/anxiety factor scored high and unstableness/stableness, shyness/boldness and praxernia/atunia were in low range of score. In defense mechanism, somaticzation and acting-out scored high and humor, suppression, altruism, avoidance and rationalization scored low. The mean BDI score was 18.25+/-9.97. The mean score of SDS were 4.88+/-3.11 in work category and 4.57+/-2.92 in social/leasure category. Male patients were significantly correlated with guit-proneness and atuia in personality factor and passive- aggressiveness, projection, denial and show-off in defense mechanism, compared with female patients (p<0.05). The patients' age was correlated with low intelligence in persolity factor and dissociation and anticipation in defense mechanism. It was negatively correlated with show-off (p<0.05). The BDI score was correlated with low intelligence, superego, unstableness, self-conflict, high superego and atunia in personality factor and dissociation and somatization in defense mechanism (p<0.05). There was a significant relationship between BDI score and SDS work category (p<0.05). CONCLUSION: Panic disorder patients show high score of tension/anxiety factor and they frequently use neurotic defense style like somatization. The depressive symptom, which depends on symptom severity, appears to have influence on work category and to cause social disability.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and to compare the difference between non-offensive and offensive types of social phobia patients. METHODS: Study subjects consisted of 28 social phobia patients diagnosed with the criteria of DSM-IV. Data were collected through Sixteen Personality Factor Questionnaire and Ehwa Diagnostic Test of Defense Mechanism. We employed was the independent sample t-test for the analysis. RESULT: Among the personality factor, the shyness/boldness factor scored lower than normal in social phobia patients. Humor drfense scored lower than normal among defense mechanisms. There was no significant correlation between non-offensive and offensive types of social phobia in personality factors and defense mechanisms. CONCLUSIONS: Social phobia patients were shier and less frequently used humor defense than the ordinary people. There was no significant correlation between non-offensive and offensive types of social phobia patients in personality factors and defense mechanisms.

Vitamin K1 dermatitis is a cutaneous adverse reaction to vitamin K1, and this malady presents as an erythematous eczematoid patch or pseudoscleroderma. At first, liver disease was thought to be related to vitamin K1 dermatitis. However, it is no longer considered as being related to liver disease due to the increasing case reports of patients with vitamin K1 dermatitis and who are without liver disease. Type IV hypersensitivity reaction was suspected to be the cause of this reaction. This disease can be easily ignored because of its low incidence. We hereby report on a case of vitamin K1 dermatitis that was confirmed by a skin test.

Kaposi's sarcoma (KS) is a multifocal proliferative vascular tumor involving cutaneous and extra-cutaneous tissues. KS has been reported in patients treated with immunosuppressive agents for autoimmune diseases. However, KS has rarely been reported in patients with iatrogenic Cushing's syndrome. A 77-year-old woman was evaluated with multiple asymptomatic violaceous nodules and plaques on both lower legs. She had been diagnosed with iatrogenic Cushing's syndrome and had been treated with low-dose corticosteroid replacement therapy for >10 years. A histopathologic study showed extensive vascular proliferation in the dermis with spindle-shaped cells. Immunohistochemical staining for CD31, CD34, human herpesvirus (HHV)-8, and D2-40 was positive. We hereby report a case of KS in a patient with iatrogenic Cushing's syndrome.

Purpose: We aimed to investigate variations in the risk of low back pain (LBP), lower extremity muscle pain, and whole body fatigue according to differences in prolonged standing work hours in relation to risk factor exposure and rest frequency. Materials and Methods: From the fifth Korean Working Conditions Survey data collected in 2017, data for 32970 full-time workers who worked for more than 1 year at their present job were analyzed. We classified the workers according to exposure to fatigue or painful postures, carrying heavy objects, performance of repetitive movements that burden the musculoskeletal system, and how often they took a break. Relationships between time spent in a standing posture at work and risks of LBP, lower extremity muscle pain, and whole body fatigue were analyzed by multivariate logistic regression. Results: Of the full-time workers in the survey, 48.7% worked in a standing position for more than half of their total working hours. A higher odds ratio (OR) value for lower extremity muscle pain was observed in female not exposed to carrying heavy objects [OR: 3.551, 95% confidence interval (CI): 3.038–4.150] and not exposed to performing repetitive movements (OR: 3.555, 95% CI: 2.761–4.557). Conclusion Changes in work methodologies are needed to lower the number of hours spent in a prolonged standing posture at work, including being able to rest when workers want to do so, to reduce pain and fatigue.
