Orofacial granulomatosis (OFG) is a rare chronic granulomatous disease of oral mucosa and maxillofacial region that clinically presents recurrent or persistent orofacial swelling. OFG may exist as an integration of the spectrum of various disorders, including Melkersson-Rosenthal syndrome, granulomatous cheilitis, Crohn’s disease, sarcoidosis, infectious diseases and delayed hypersensitivity reaction to food additives, dental materials. Precise etiology is not yet to be elucidated. Herein, we report two rare cases of orofacial granulomatosis who presented similar clinical manifestation of lip swelling but was diagnosed as a sarcoidosis and as a granulomatous cheilitis.

A 44-year-old male presented with 7 months history of nonpruritic round oozing plaques on the extremities and red papules on the trunk. The lesions were resistant to topical and oral steroid prescribed at the other local clinics. Histopathological examination showed parakeratosis with acanthosis and rete ridge elongation as well as spongiotic intraepidermal blisters and dense dermal infiltration of small to medium sized atypical lymphoid cells. Immunohistochemical analysis revealed the lymphocyte infiltrate to be predominantly CD4 + T cells, with CD4/CD8 ratio to be greater than 10:1. Infiltration of large cells that were CD30 + were also noted. This histopathologic findings are consistent with vesicular mycosis fungoides (MF). He was prescribed with narrow-band ultraviolet B twice per week and topical steroid, combined with interferon-α injection for 5 weeks, and his skin lesions significantly faded and were flattened. Vesicular MF is associated with poor prognosis, but our patient was able to show benign course of disease thanks to timely diagnosis. One must consider vesicular MF as a differential for recalcitrant eczematous lesions.

BACKGROUND/OBJECTIVES: Although aged black garlic has various biological activities such as anti-allergy, anti-inflammation and neuroprotection, effect of aged black garlic on chemically contact dermatitis is unclarified. MATERIALS/METHODS: To evaluate anti-dermatitic activity of aged black garlic extract, we investigated effects of a fraction of aged black garlic extract (BG10) on both in vivo and in vitro. RESULTS: BG10 almost inhibited formation of nitric monoxide and interleukin-6 (IL-6; IC50, 7.07 µg/mL) at 25 µg/mL, and dose-dependently reduced production of tumor necrosis factor-α (TNF-α; IC50, 52.07 µg/mL) and prostaglandin E2 (IC50, 38.46 µg/mL) in lipopolysaccharide-stimulated RAW264.7 cells. In addition, BG10 significantly inhibited the expression of inducible nitric oxide synthase, cyclooxygenase-2 and nuclear NF-κB, and improved that of cytosolic levels of NF-κB and IκBα in the cells. Consistent with in vitro studies, BG10 (0.5 mg/mL) not only reduced ear edema but also suppressed the formation of IL-6 and TNF-α induced by 12-O-tetradecanoylphorbol-13-acetate in ear tissues of mice. CONCLUSIONS: These findings suggest BG10 has anti-dermatitic activity through inhibiting activation of macrophages. Therefore, such effects of BG10 may provide information for the application of aged black garlic for prevention and therapy of contact dermatitis.

OBJECTIVE: To evaluate the reliability of the practical life space in post-stroke patients using the Korean version of the Life-Space Assessment (K-LSA) questionnaire and to assess the relationships between the K-LSA and physical function, daily activity, quality of life, and post-stroke depression. METHODS: The LSA questionnaire was translated into Korean, and the translated version was authorized by the author of the LSA questionnaire. In a cross-sectional study, the performance of the K-LSA was evaluated in 34 stroke patients (20 males and 14 females; mean age 65.11±2.39 years) who were receiving physical and occupational therapy at the outpatient clinic in the rehabilitation medicine department of a university medical center at the time of evaluation. Performances were assessed twice by one examiner at a 2-week interval to test the reliability. The patients were evaluated using the Functional Ambulation Category (FAC) scale, Functional Independence Measure (FIM) scale, and mobility subscale of the FIM to assess their relationships with the K-LSA. They were also evaluated using the EuroQol 5 Dimensions questionnaire (EQ-5D) and Geriatric Depression Scale (GDS) to determine the relationship with quality of life and post-stroke depression. RESULTS: Test-retest reliability at the first (62.20±32.14) and second (63.15±32.22) assessment was 0.993 (p<0.01). The K-LSA showed significant correlations with the FAC (r=0.848, p<0.01), FIM (r=0.765, p<0.01), mobility category of the FIM (r=0.764, p<0.01), GDS (r=-0.657, p<0.01), and EQ-5D (r=0.506, p<0.01). CONCLUSION: This study suggests that the practical life space of post-stroke patients, assessed by the K-LSA, has a significant correlation with patients' functional mobility, independence in daily activity, quality of life, and depression.

OBJECTIVE: To evaluate the reliability and validity of Korean version of AST (K-AST) as a bedside screening test of apraxia in patients with stroke for early and reliable detection. METHODS: AST was translated into Korean, and the translated version received authorization from the author of AST. The performances of K-AST in 26 patients (21 males, 5 females; mean age 65.42±17.31 years) with stroke (23 ischemic, 3 hemorrhagic) were videotaped. To test the reliability and validity of K-AST, the recorded performances were assessed by two physiatrists and two occupational therapists twice at a 1-week interval. The patient performances at admission in Korean version of Mini-Mental State Examination (K-MMSE), self-care and transfer categories of Functional Independence Measure (FIM), and motor praxis area of Loewenstein Occupational Therapy Cognitive Assessment, the second edition (LOTCA-II) were also evaluated. Scores of motor praxis area of LOTCA-II was used to assess the validity of K-AST. RESULTS: Inter-rater reliabilities were 0.983 (p<0.001) at the first assessment and 0.982 (p<0.001) at the second assessment. For intra-rater (test-retest) reliabilities, the values of four raters were 0.978 (p<0.001), 0.957 (p<0.001), 0.987 (p<0.001), and 0.977 (p<0.001). K-AST showed significant correlation (r=0.758, p<0.001) with motor praxis area of LOTCA-II test. K-AST also showed positive correlations with the total FIM score (r=0.694, p<0.001), the selfcare category of FIM (r=0.705, p<0.001) and the transfer category of FIM (r=653, p<0.001). CONCLUSION: K-AST is a reliable and valid test for bedside screening of apraxia.

Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.

The role of alveolar macrophages (AMs) in the pathogenesis of asthma is still unknown. The aim of the present study was to investigate the effects of AM in the murine model of asthma. AMs were selectively depleted by liposomes containing clodronate just before allergen challenges, and changes in inflammatory cells and cytokine concentrations in bronchoalveolar lavage (BAL) fluid were measured. AMs were then adoptively transferred to AM-depleted sensitized mice and changes were measured. Phenotypic changes in AMs were evaluated after in vitro allergen stimulation. AM-depletion after sensitization significantly increased the number of eosinophils and lymphocytes and the concentrations of IL-4, IL-5 and GM-CSF in BAL fluid. These changes were significantly ameliorated only by adoptive transfer of unsensitized AMs, not by sensitized AMs. In addition, in vitro allergen stimulation of AMs resulted in their gaining the ability to produce inflammatory cytokines, such as IL-1beta, IL-6 and TNF-alpha, and losing the ability to suppress GM-CSF concentrations in BAL fluid. These findings suggested that AMs worked probably through GM-CSF-dependent mechanisms, although further confirmatory experiments are needed. Our results indicate that the role of AMs in the context of airway inflammation should be re-examined.

In this study, we evaluated an edge detector for small-beam dosimetry. We measured the dose linearity, dose rate dependence, output factor, beam profiles, and percentage depth dose using an edge detector (Model 1118 Edge) for 6-MV photon beams at different field sizes and depths. The obtained values were compared with those obtained using a standard volume ionization chamber (CC13) and photon diode detector (PFD). The dose linearity results for the three detectors showed good agreement within 1%. The edge detector had the best linearity of +/-0.08%. The edge detector and PFD showed little dose rate dependency throughout the range of 100~600 MU/min, while CC13 showed a significant discrepancy of approximately -5% at 100 MU/min. The output factors of the three detectors showed good agreement within 1% for the tested field sizes. However, the output factor of CC13 compared to the other two detectors had a maximum difference of 21% for small field sizes (~4x4 cm2). When analyzing the 20~80% penumbra, the penumbra measured using CC13 was approximately two times wider than that using the edge detector for all field sizes. The width measured using PFD was approximately 30% wider for all field sizes. Compared to the edge detector, the 10~90% penumbras measured using the CC13 and PFD were approximately 55% and 19% wider, respectively. The full width at half maximum (FWHM) of the edge detector was close to the real field size, while the other two detectors measured values that were 8~10% greater for all field sizes. Percentage depth doses measured by the three detectors corresponded to each other for small beams. Based on the results, we consider the edge detector as an appropriate small-beam detector, while CC13 and PFD can lead to some errors when used for small beam fields under 4x4 cm2.

Polymyalgia rheumatica is an inflammatory disease affecting elderly and involving the shoulder and pelvic girdles. No epidemiological study of polymyalgia rheumatica was conducted in Korea. We retrospectively evaluated patients with polymyalgia rheumatica followed up at the rheumatology clinics of 10 tertiary hospitals. In total 51 patients, 36 patients (70.6%) were female. Age at disease onset was 67.4 yr. Twenty-three patients (45.1%) developed polymyalgia rheumatica in winter. Shoulder girdle ache was observed in 45 patients (90%) and elevated erythrocyte sedimentation rate (> 40 mm/h) in 49 patients (96.1%). Initial steroid dose was 23.3 mg/d prednisolone equivalent. Time to normal erythrocyte sedimentation rate was 4.1 months. Only 8 patients (15.7%) achieved remission. Among 41 patients followed up, 28 patients (68.3%) had flare at least once. Number of flares was 1.5 +/- 1.6. The frequency of flare was significantly lower in patients with remission (P = 0.02). In Korea, polymyalgia rheumatica commonly develops during winter. Initial response to steroid is fairly good, but the prognosis is not benign because remission is rare with frequent relapse requiring long-term steroid treatment.

OBJECTIVES: This clinical study aimed to investigate if dentifrices containing policresulen would help to control dental plaque and gingivitis. METHODS: Seventy-eight eligible adults participated in this double-blind and randomized clinical study after an initial oral examination, calculus removal, and tooth prophylaxis. Two weeks after the procedure, the participants were assigned to three groups using the following dentifrices: (1) a dentifrice containing 0.22% NaF (control group); (2) a dentifrice containing 0.22% NaF and 100 ppm policresulen (policresulen group); and (3) a dentifrice containing 0.22% NaF, 100 ppm policresulen, and 1.00% bamboo salt (policresulen/bamboo group). The participants used only the provided dentifrice (for 1 min, twice a day, over 8 weeks) when brushing their teeth and followed their normal brushing habits. Dental plaque accumulation and gingivitis measurements were conducted using the Turesky modification of the Quigley-Hein plaque index (PI), the Loe and Silness gingival index (GI), and the percent bleeding on probing (%BOP) to obtain baseline data and 4- and 8-week data after grouping. RESULTS: A total of 73 participants aged 35.92+/-11.46 years (mean+/-SD) completed the study. The results after 8 weeks demonstrated statistically significant group-by-time interactions for PI, GI, and %BOP (P<0.001). The PI observed in the control groups increased over time up to 6%, while that observed in the dentifrice groups containing policresulen decreased by 5% (P<0.001). For GI and %BOP, the control group exhibited significantly higher values after 8 weeks, while the policresulen and the policresulen/bamboo groups revealed similar index values as the baseline after 4 and 8 weeks. The changes in all indices were significantly different between the control and the two experimental groups. There were no significant differences in the results obtained from the policresulen/bamboo group and the results obtained from the policresulen group. CONCLUSIONS: Use of dentifrices containing policresulen over 8 weeks demonstrated anti-plaque and anti-gingivitis efficacy compared to a control dentifrice.
