OBJECTIVE: Accelerometer is a convenient device that can easily measure human movement. The purpose of this study was to evaluate its usefulness in the assessment of hemiparetic gait after stroke. METHOD: Twenty hemiparetic stroke patients were enrolled in the study. A portable accelerometer was attached between L3,4 intervertebral area. Vertical and medio-lateral acceleration was measured while walking 10 m. Walking ability of each subject was classified by Functional Walking Category (FWC). RESULTS: Accelerometric parameters, such as walking speed, a mean amount of peak vertical acceleration in one gait cycle, mean peak value of unaffected side, peak vertical acceleration ratio, step time ratio were significantly higher in groups of FWC 4, 5, 6 than in groups of FWC 2, 3. In subjects using cane there was an extra peak other than peaks observed in non-users. Mean peak value, step length of unaffected side and cadence were significantly higher in non-users than in users. CONCLUSION: Trunk accelerometer can be used as an objective method to evaluate walking ability in hemiparetic patients after stroke.

We report a case of gastric pseudoterranoviasis proven by gastrofiberscopy on Dec. 13, 1994. The 34-year-old male patient, residing in Chungju-shi, was admitted to Konkuk University Hospital complaining of prickling epigastric pain. The symptoms suddenly attacked him two days after eating raw marine fish at Chonan-shi. By the gastrofiberscopic examination, a long white-yellowish nematode was found from the fundus region of stomach. The worm was 34.50 x 0.84 mm in size, and was identified as a 3rd stage larva of Pseudoterranova decipiens judging from the position of the intestinal cecum. This is the 12th confirmed case of human pseudoterranoviasis in Korea.

PURPOSE: This study aims to analyse the epidemiologic characteristics of burn in the elderly and to discusses a possible prevention program for this population. METHODS: A retrospective review of all medical records of elderly patients (above 60 years old) admitted with burns to the burn center of the Hanil General Hospital from January 1996 to December 2007 was carried out. Patient demographics, etiology, extent, and type of burn, seasonal variation, and mortality rates were reviewed. RESULTS: A total of 537 elderly patients (mean age of 69.8 years, median age of 68 years, range 60~97 years) was admitted. The gender ratio of the patients was 1:.5 with 217 men and 320 women. The most common causes were scald burn (44.9%) and flame burn (35.4%). The average total body area burned was 13.5% (range 0~95%). Twenty six patients (4.8%) died. CONCLUSION: In elderly patients, scald burns are more common in women but flame burns are more common in men. The mortality rate is higher in flame burns and men

BACKGROUND: Despite of numerous researches on the mechanisms and new therapeutic methods of chronic pain, patients are still suffering even with the help of opioids. In recent years, however, with the development of molecular-biology cell transplantation gives us a new chance for treating intractable chronic pain. The major purpose of the present study was to determine if the chromaffin cells have robust analgesic effects in the spinal atlanto-occipital subarachnoid space even without nicotine stimulation. METHODS: In order to determine whether cultured bovine adrenal medullary chromaffin cells transplanted in the spinal cord can produce analgesic effects, we purified adrenal medullary chromaffin cells and implanted them into the subarachnoid space of rats' (n = 10) spinal cord without immunosuppression, and investigated the hot sensitivity of rats' hind-paw by a light-beam test. RESULTS: It was found that compared with the control group, hot response latency of the group which received adrenal medullary chromaffin cells had increased at 14 days and the analgesic efficacy was maintained for at least 3 months. CONCLUSIONS: Adrenal medullary chromaffin cells transplanted in the rats' spinal cord may provide a permanent and locally available source of neuropeptides for the relief of intractable pain. Furthermore, these kinds of analgesic effect even produced without any stimulation such as nicotine.

BACKGROUND: The intrathecal grafting of adrenal chromaffin cells as a potential analgesic source, to delivery analgesic substances such as catecholamines and opioid peptides, is known to be effective at treating acute and chronic pain in several animal pain models. We tested whether the intrathecal implantation of encapsulated bovine chromaffin cells reduces cold allodynia in a rat model of neuropathic pain induced by chronic constriction injury of the sciatic nerve. METHODS: Bovine adrenal medullary chromaffin cells microencapsulated in sodium alginate-poly-l-lysin-alginate (APA) were implanted into the subarachnoid space of rats (n = 10) and foot cold sensitivity was investigated using an acetone test. At the end of the study, histology and capsule catecholamine production were evaluated. RESULTS: A significant reduction in cold allodynia was observed in animals implanted with chromaffin cells. In addition, the suppression of cold allodynia was reversed by naloxone. Abundant clusters of viable chromaffin cells stained with neutral red, were observed in the retrieved implants and after nicotine stimulation, and catecholamine was quantified. An ultrastructural study showed no fibrotic reaction against capsules, or disorganised capsules. CONCLUSIONS: These results suggest that intrathecal encapsulated chromaffin cells act as "mini pumps", which continuously deliver analgesic substances and produce analgesia in this chronic pain model of nerve injury-without immunosuppressant.

PURPOSE: The purpose of this study was to analyze the antimicrobial, antioxidant activity and cytotoxicity of Dendropanax morbifera Léveille extract for assessing whether Dendropanax morbifera Léveille can be used for the development of natural mouthwash and denture cleaning solution. MATERIALS AND METHODS: The extract was obtained from branches of Dendropanax morbifera Léveille. The solvent fractions were acquired by fractionating Dendropanax morbifera Léveille extract using n-hexane, ethyl acetate, chloroform and butanol solvent. Paper disc test was used to evaluate the antimicrobial and antifungal activity of Dendropanax morbifera Léveille extract and solvent fractions against Streptococcus mutans and Candida albicans. The analysis of antioxidant activity was carried out through DPPH radical scavenging assay. The cytotoxicity of Dendropanax morbifera Léveille extract was analyzed through MTT assay using normal human oral keratinocytes. RESULTS: Dendropanax morbifera Léveille extract showed antimicrobial activity against Streptococcus mutans and especially Candida albicans. The solvent fractions of Dendropanax morbifera Léveille showed strong antimicrobial activity against Streptococcus mutans and Candida albicans in n-hexane and butanol solvent fraction, respectively. Dendropanax morbifera Léveille extract also showed outstanding antioxidant activity. Butanol, ethyl acetate, and chloroform solvent fraction of Dendropanax morbifera Léveille tended to have increased antioxidant activity as the concentration increased. Dendropanax morbifera Léveille extract showed high cell survival rate in cytotoxicity test. CONCLUSION: Dendropanax morbifera Léveille extract turned out to have antimicrobial, antioxidant activity and cytophilicity. Based on these results, it is expected that Dendropanax morbifera Léveille is applicable as an ingredient for natural mouthwash and denture cleanser.

BACKGROUND: Dense breast reduced the sensitivity of mammography in breast cancer screening and known as an independent risk factor of breast cancer. The relationship between breast density and age, body mass index has studied. However, there are few studies on the relationship between breast density and lifestyle related disease. In this study, we investigated the relationship between mammographic breast density and lifestyle related disease. METHODS: Retrospective cross sectional research was carried out from people who visited a single health screening center in Busan from January 2015 to December 2015. We investigated age, past history of the subjects and measured their height, weight, blood pressure and waist circumference. The biochemical test was carried out using their blood. All patients underwent mammography. The breast density on mammography determined by the basis of American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) breast composition and 996 people was recruited. RESULTS: In the distribution of breast density, 16.3% of women (n=160) had dense breast. Age (under 49), body mass index (BMI) (underweight) were positively correlated with the BI-RADS composition category 3, 4 but the number of lifestyle related disease were negatively correlated (age ρ=0.17, BMI ρ=0.39, the number of lifestyle related disease ρ=-0.21). The odds ratio (OR) of dense breast increased with decreasing lifestyle related disease severity (OR=3.06, 95% confidence interval: 1.13-8.22, P=0.027). CONCLUSIONS: This study showed that the number of lifestyle related disease was negatively correlated with mammographic density. The OR of dense breast increased with decreasing lifestyle related disease severity. Therefore, primary physicians should consider negative correlation between breast density and lifestyle related disease in breast cancer screening.

Chronic urticaria may often be associated with interleukin (IL)-1-mediated autoinflammatory disease, which should be suspected if systemic inflammation signs are present. Here, we report a case of Schnitzler's syndrome without monoclonal gammopathy treated successfully with the IL-1 receptor antagonist anakinra. A 69-year-old man suffered from a pruritic urticarial rash for 12 years. It became aggravated episodically and was accompanied by high fever, arthralgia, leukocytosis, and an elevated C-reactive protein and erythrocyte sedimentation rate. The episodes each lasted for over one week. Neutrophilic and eosinophilic inflammation was found on skin biopsy. However, serum and urine electrophoresis showed no evidence of monoclonal gammopathy. The cutaneous lesions were unresponsive to various kinds of anti-histamines, systemic glucocorticoids, colchicine, cyclosporine, dapsone, and methotrexate, which were administered over a span of 3 years immediately preceding successful treatment. A dramatic response, however, was observed after a daily administration of anakinra. This observation suggests that the correct diagnosis of this case is Schnitzler's syndrome without monoclonal gammopathy. For an adult patient with refractory chronic urticaria and systemic inflammation, Schnitzler's syndrome could be considered as a possible differential diagnosis. Although the typical form of Schnitzler's syndrome exhibits the presence of monoclonal gammopathy as a diagnostic criterion, monoclonal gammopathy may be absent in an atypical form. In such a situation, an IL-1 antagonist should be effective for the management of chronic urticaria.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions. Although viral reactivation is associated with DRESS syndrome, its role in TEN remains unclear. An 80-year-old woman visited our hospital because of fever and skin eruption. DRESS syndrome was diagnosed and was thought to caused by the use of the drug allopurinol. She was treated by discontinuation of the drug and administration of systemic steroids. She recovered from DRESS syndrome and was discharged from the hospital with tapering doses of steroids prescribed. One week after discharge, she visited our hospital again as the skin rash recurred and oral pain as well as oral and ocular mucosal lesions developed. In addition to the skin rash, blisters and Nikolsky's sign that were different from the skin lesions present in the previous DRESS syndrome were observed. Unlike those in DRESS syndrome, the viral serological test results were positive for anti-cytomegalovirus (CMV) IgM and CMV polymerase chain reaction. Therefore, it was thought that TEN was due to reactivation of CMV and she was treated this with ganciclovir and intravenous immunoglobulin. Here, we report a case of TEN caused by viral reactivation after DRESS syndrome developed after use of allopurinol which recovered after steroid treatment.

PURPOSE: We aimed to analyze the frequency of eosinophilia-associated diseases and to search for possible markers that may be useful for their differential diagnosis. METHODS: We retrospectively reviewed the medical records of 148 patients with peripheral blood eosinophil count of more than 500/µL who visited the Allergy Department of Chonnam National University Hospital for the first time from January to December 2016. Blood eosinophilia was categorized as mild (<1,500/µL), moderate (1,500–5,000/µL), and severe (>5,000/µL). RESULTS: Blood eosinophilia was mostly caused by allergic diseases (41.9%), parasitic infestation (23.6%), and drug allergy (19.6%). Eosinophil count was higher in patients with parasitic infestation (P<0.01), drug allergy (P<0.01), hypereosinophilic syndrome (HES, P<0.001), or eosinophilic granulomatosis with polyangiitis (EGPA, P<0.001) than in those with allergic diseases. The eosinophilic cationic protein level was higher in patients with HES than in those with allergic diseases (P<0.05) and parasitic infestation (P<0.05). The total IgE level was lower in patients with HES than in those with parasitic infestation (P<0.05) and EGPA (P<0.05). The vitamin B12 level was higher in patients with HES than in those with parasitic infestation (P<0.05). There was no statistically significant difference in tryptase levels between the groups. The most common cause of mild eosinophilia was allergic diseases (59.8%), followed by parasitic infestation (22.7%) and drug allergy (13.4%). The common causes of moderate eosinophilia were drug allergy (37.8%), parasitic infestation (29.7%), and allergic diseases (10.8%). The common causes of severe eosinophilia were EGPA (28.6%), HES (21.4%), parasitic infestation (14.3%), and drug allergy (14.3%). CONCLUSION: Common causes of blood eosinophilia in patients who visit the allergy department are allergic diseases, parasitic infestation, and drug allergy. Several markers, including eosinophil count, total IgE, and vitamin B12, may be useful for the differential diagnosis of eosinophilia-associated diseases.
