Angiomyofibroblastoma is a rare, benign mesenchymal tumor of the vulva. Since it was described in 1992 by Fletcher, 15 cases have been reported in literature. We recently experienced a recurred angiomyofibroblastoma of the vulva. A 45-year-old woman was presented initially in 1991 with a mass of labium major and local excision of tumor mass had been performed. A histologic diagnosis was made of angiomyxoma, but this diagnosis was revised to angiomyofibroblastoma by the authors. The recurred mass was well circumscribed, measuring 2.5x1.6x1.5cm in dimensions. Microscopically the tumor was characterized by high cellularity, numerous blood vessels(which lack prominent hyalinization), and plump stromal cells. Immunohistochemically, the stromal cells were reactive for vimentin and desmin, but not alpha-smooth muscle actin, or S-100 protein. We thought that this case was a recurred angiomyofibrblastoma of the vulva due to incomplete surgical excision.

OBJECTIVE: To evaluate the effects of botulinum toxin A (BT) dilution volume and post- injection exercise with electrical stimulation on muscle paralysis. METHOD: Eighteen New Zealand white rabbits are randomly assigned to 0.1 ml dilution group, 0.5 ml dilution group or control group. Control group did not receive any injection and 10 units of BT was diluted with 0.1 ml (B1) or 0.5 ml (B5) normal saline and injected to the both gastrocnemius muscles. The right lower limbs of experimental groups did not have any treatment after botulinum toxin A injection (B1C, B5C) and left lower limbs had stretching exercise after injection (B1S, B5S) for 2 hours using the pneumatic kicking machine. Electrical stimulation was also applied to the gastrocnemius muscle with the intensity of 20 mA to 30 mA to evoke plantar flexion of ankle joint. Muscle paralysis effect of BT was evaluated with compound muscle action potential (CMAP) amplitude of gastrocnemius muscle with the sciatic nerve stimulation before and 1 week after injection. RESULTS: There were significant CMAP amplitude decreases in all animals after BT injection. There were significant decreases of CMAP amplitudes in B5 group compared with that of B1 group (p<0.001). Left limbs with stretching exercise and electrical stimulation showed lower CMAP amplitude (p=0.01) compared with right limbs which did not have any treatment after BT injection. CONCLUSION: To maximize muscle paralysis effect of the botulinum toxin A, increasing dilution volume and performing post-injection stretching exercise with electrical stimulation are considered a good strategy.

Spark’s nevus is a compound word composed of Spitz nevus and Clark’s nevus. It is one of the combined melanocytic nevi which is more common in female and usually presents as a sharp circumscribed hyperpigmented macule on the lower extremities. On histopathologic findings, both cytologic features of Spitz nevus characterized as large spindle or epithelioid melanocytes containing large nuclei with abundant cytoplasm, and architecture of Clark’s nevus characterized as elongation of rete ridges, bridging of the nests, concentric and lamellar fibrosis can be seen. A 24-year-old female presented with an asymptomatic, solitary, dark-brown-colored papule surrounded by brownish patch that looked similar to dysplastic nevus or malignant melanoma on the buttock. On dermoscopic examination, it showed brown-to-black globules, diffuse homogenous pigmentation with blue-white structures, and a surrounding brownish reticular pattern that faded away. On histopathologic findings, overall asymmetrical structure, epithelioid large melanocytes containing large nuclei with abundant cytoplasm, and Kamino body were seen in the central portion. Also, lentiginous hyperplasia, bridging of the nests composed of melanocytes containing foamy cytoplasm, concentric and lamellar fibrosis along with the elongation of rete ridge, and perivascular lymphocytic infiltration were seen in the peripheral portion. The diagnosis of Spark’s nevus was made. Following its definition, this combined nevus is diagnosed histopathologically, but the clinicodermoscopic features have not been well described. Herein, we report a case of Spark’s nevus in which dermoscopy was helpful for differentiating it from malignant melanoma.

There is no consensus on whether it is safe to re-administer tumor necrosis factor-alpha (TNFalpha) inhibitors in patients with rheumatoid arthritis (RA) or ankylosing spondylitis (AS) flared after withdrawal of TNFalpha inhibitors due to active tuberculosis (TB). We evaluated the safety of restarting anti-TNFalpha therapy in patients with TNFalpha-associated TB. We used data of 1,012 patients with RA or AS treated with TNFalpha inhibitors at Seoul St. Mary's Hospital between January 2003 and July 2013 to identify patients who developed active TB. Demographic and clinical data including the results of tuberculin skin tests (TST) and interferon-gamma releasing assays (IGRA) were collected. Fifteen patients developed active TB. Five cases were occurred in RA and 10 cases in AS. Nine of 15 patients had a negative TST or IGRA and 6 TST-positive patients had received prophylaxis prior to initiating anti-TNFalpha therapy. All patients discontinued TNFalpha inhibitors with starting the treatment of TB. Eight patients were re-administered TNFalpha inhibitors due to disease flares and promptly improved without recurrence of TB. TNFalpha inhibitors could be safely resumed after starting anti-TB regimen in patients with RA or AS.

Objective:
We developed the Indoor Cognitive Training combined with Physical Activity (ICT-PA) program, incorporating memory registration, navigation, and image recall through wearable sensors and Bluetooth Low Energy tags, aimed at enhancing cognitive function and physical activity in elderly individuals with mild cognitive impairment (MCI).
Methods:
Thirty-six elderly individuals over 60 years diagnosed with MCI participated in a 6-week ICT-PA program. The primary outcome measure was the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery Total Score 1 (CERAD-TS1), and the secondary outcome measures were the Mini-Mental State Examination (MMSE), Subjective Memory Complaints Questionnaire (SMCQ), and Korean version of the Geriatric Depression Scale (GDS-KR). Changes in scores before and after the program were analyzed using paired t-tests. Program satisfaction was evaluated using a 5-point Likert scale.
Results:
CERAD-TS1 scores significantly improved after ICT-PA training (pre 57.3±11.3; post 60.3±13.1; p=0.006), while MMSE, SMCQ and GDS-KR scores remained unchanged. Subgroup analysis showed significant CERAD-TS improvements in the compliance group (>360 minutes of ICT-PA use) (pre 58.5±11.7; post 62.7±12.9; p=0.002). The average program satisfaction score was 7.7±1.6 out of 10. Data are presented as mean±standard deviation.
Conclusion
The ICT-PA program effectively improved cognitive functions in MCI patients, with high satisfaction rates.

BACKGROUND: Legionella pneumophila has been recognized as an important cause of community-acquired pneumonia(CAP) requiring hospitalization. However, epidemiological data on the occurrence of legionella-related pneumonia is unavailable in Korea. The purpose of this study was to evaluated the etiological imprtance of legionella pneumophila serogroup 1 in patients hospitalized with CAP. METHOD: The CAP patient over 16 year-old were recruited from July 1999 to June 2000 at the Chunchon Sacred Heart Hospital. Fifty four patients (male 29, female 25, average age 63.8±15.3) were included in this study. A diagnosis of a legionella pneumophila infection was based on a urinary antigen test using the Binax Company enzyme immunoassay. The severity of pneumonia was assessed using the Fine's PORT scoring system. RESULT: The average Fine's PORT score was 99.7(±44.9). According to the risk classification proposed by the Infectious Disease Society of America, the number of patients in each class(from class I to class V) were 6(11.1%), 13(24.1%), 9(16.7%), 14(25.8%), and 12(22.2%), respectively. Thirty two patients(59.3%) were initially admitted to the intensive care unit. The mortality rate was 16.7%(9 in 54). In all patients, urinary antigens to Legionella pneumophila serogroup 1 were not detected. CONCLUSION: Legionella pneumophila may play little role in causing adult CAP in Korea. Therefore, the routine use of macrolide in the empirical treatment of the CAP patients based upon the ATS guidelines(1993) in Korea should be reevaluated.

PURPOSE: To investigate bioartificial vessels capable of being used for vascular grafts, we studied cell-polymer constructs from venous smooth muscle cells (SMCs) and biodegradable scaffolds using the canine model. METHODS: Scaffolds constructed from 50/50 poly (D,L-Lactide-co-glycolide) (PLGA) were created with pores containing gelatin particles. Disk type scaffolds were used as templates of cell attachment and vascular tissue regeneration. SMCs were isolated from canine external jugular veins and primary SMCs cultures were produced with the explant-derived method. SMCs were seeded into the scaffolds and cultured statically for 4 weeks. The cell-polymer constructs were examined histochemically and using scanning electron microscopy. RESULTS: The SMCs obtained by the explant-derived method were confirmed with immunohistochemical staining using an anti-smooth muscle actin antibody. Four weeks after the SMCs were seeded into the scaffold, histological examination showed SMCs infiltration into the scaffold wall and scanning electron microscopy revealed the SMCs mass which resembled tissue on the scaffold surface. CONCLUSION: This is a pilot study for the constructing artificial vessels using tissue engineering. The construction of the ideal scaffold for vessel and the improvement of culture methods in vitro are the most important parts in this field.

BACKGROUND/AIMS: We investigated the clinical characteristics and follow-up findings of subjects with adrenal incidentalomas in a single, tertiary-care hospital in South Korea. METHODS: The study consisted of a retrospective analysis of 282 adrenal incidentaloma patients who underwent radiographic and endocrinological evaluations at Samsung Medical Center in Seoul, South Korea, between January 2004 and July 2011. RESULTS: Most (86.2%) of the subjects were found to have nonfunctioning tumors. Functioning tumors were seen in 39 patients (13.8%). Among them, 28 (9.9%) had subclinical Cushing syndrome (SCS), six (2.1%) had pheochromocytoma, and five (1.8%) had primary hyperaldosteronism. Malignant adrenal tumors were discovered in three cases: two (0.7%) were primary adrenal cancers, and one (0.4%) was a secondary metastasis from a lung cancer. Significant risk factors for functional tumors were female gender (odds ratio [OR], 3.386; 95% confidence interval [CI], 1.611 to 7.117; p = 0.0013) and a noncontrast attenuation value of > 10 Hounsfield units (OR, 2.806; 95% CI, 1.231 to 6.397; p = 0.0141). During follow-up (mean, 22.5 months) of 72 of the patients, three (4.2%) developed hormonal changes due to functional tumors. One was confirmed as pheochromocytoma by histopathology, and the others were diagnosed with SCS and followed routinely without surgical intervention. No malignant transformation was found in these patients. CONCLUSIONS: Based on these findings, initial hormonal and radiographic evaluations for adrenal incidentalomas appear to be more important than follow-up tests because functional or malignant changes are rare.
