OBJECTIVE: We investigated a possible use of the induced apoptosis as a biomarker in the cells and their media treated with commonly used anti-cancer agents in gynecologic malignancies. METHODS: After treatments with low and high concentrations of paclitaxel, cisplatin, and camptothecin in HeLa and OVCAR-3 cells, the levels of M30 antigen were detected in the cells and their media by immunofluorescence staining and ELISA methods, respectively. RESULTS: The percentages of M30-fluoresein isothiocyanate (FITC) positive cells in HeLa and OVCAR-3 cells treated with paclitaxel, cisplatin, and camptothecin were 4.3% vs 18.1% vs 34.87% and 4.07% vs 18.6% vs 32.63%, 4.3% vs 17.87% vs 32.38% and 4.07% vs 16.83% vs 32%, and 4.3% vs 16.75% vs 31.3% and 4.07% vs 15.18% vs 29.9% in control, low dose, and hight dose groups, respectively (P<0.001). M30 antigen levels (U/L) measured in culture media of HeLa and OVCAR-3 cells treated with paclitaxel, cisplatin, and camptothecin were 53.03 vs 101.53 vs 355.59 and 86 vs 114.41 vs 412.04, 53.03 vs 79.84 vs 327.64 and 86 vs 125.44 vs 385.09, and 53.03 vs 88.41 vs 295.005 and 86 vs 108.42 vs 263.1 in control, low dose, and hight dose groups, respectively (P<0.001). CONCLUSION: Our results obtained in this preclinical study suggests that measurement of the levels of M30 antigen may help to predict the clinical responses and to select the effective anti-cancer agents in clinical settings, rapidly and quantitatively.

OBJECTIVE: The aim of this study was to detect the levels of M30-antigens as a biomarker of apoptosis in cells and their culture media after treatments with anticancer drugs as a preclinical study. METHODS: After HeLa and OVCAR-3 cells were treated respectively with paclitaxel, cisplatin, and camptothecin, the harvested cells were stained sequentially with M30 monoclonal antibodies and propidium iodide (PI). Afterwards, they were analyzed using a FACScan flow cytometer and observed under an immunofluorescence microscope for M30-FITC immunofluorescences. Levels of M30 antigens were also detected in their culture media using M30-Apoptosense ELISA kit. RESULTS: The levels of M30-FITC immunofluorescences were elevated in both cell lines after each drug treatments compared with those of control cells. The levels of M30 antigens detected by ELISA in media culturing each cell line treated with each of drugs were elevated compared with those of control cells. CONCLUSION: This study suggests that M30-antigens representing chemotherapy induced apoptosis may be a useful biomarker for predicting and monitoring the response of neoadjuvant chemotherapy in patients with gynecologic cancers.

Myxoid neurofibroma is a benign tumor of perineural cell origin, which is demonstrated with a positive immunohistochemical stainig for S-100. The most common locations of the myxoid neurofibroma are face, shoulder, arm, periungual and foot. We experienced an unusual case of myxoid neurofibroma which originated from labia majora area then reported it. To our knowledge, this is the first time that a labia majora location is reported.

Acrodysostosis is an extremely rare disorder characterized by short fingers and toes with peripheral dysostosis, nasal hypoplasia, and mental retardation. We report a 16-year-old Korean boy with acrodysostosis who had characteristic clinical features and cervical spine stenosis manifested by neurologic symptoms. On presentation, he complained of difficulty in raising his arms, and suffered from intermittent pain and weakness in both upper extremities. He had short stature and dysmorphic facial features, including a broad, depressed nasal bridge, small, upturned nose, bilateral epicanthal folds, and mild hypertelorism. Moderate mental retardation and sensorineural hearing loss in both ears were also present. Radiological findings included broad, short metacarpals and phalanges with cone-shaped epiphyses, bilateral Madelung deformities, hypertrophied first metatarsals, and thickening of the calvarium. Magnetic resonance imaging findings included stenosis of the cervical spine, platybasia with compression into the cervicomedullary junction, and downward displacement of the cerebellar tonsils. Here, we report a case of acrodysostosis with symptoms and signs of cervical spinal stenosis first in Korea. If it is diagnosed in the early stages, possible life-threatening complications, including spinal canal stenosis, can be managed properly and permanent neurologic sequelae might be avoided. Therefore, it is important to consider acrodysostosis in the differential diagnosis of peripheral dysostosis.

OBJECTIVE: To investigate the treatment efficacy between low and high dose of triamcinolone acetonide in the treatment of ultrasonographic-guided subacromial bursa injection. METHOD: Forty two patients with periarticular shoulder disorders were randomly assigned to receive injection with 10 mg (group 1, 20 patients) or 40 mg (group 2, 22 patients) triamcinolone acetonide. After a single injection, participants were followed up for 6 weeks. Treatment efficacy was measured upon pre-treatment and post-treatment on week 1, 3, 6, using visual analog scale for average pain intensity during 24 hours (24 h VAS), Shoulder Function Assessment scale (SFA), Shoulder Disability Questionnaire (SDQ), and active range of motion (AROM). Participants and the assessor were blinded for group assignment. RESULTS: Six weeks after injection, the 24 h VAS, the SFA, the SDQ, and the AROM (internal rotation, external rotation, and abduction) showed a significantly greater improvement in group 2 than group 1 (p <0.05). CONCLUSION: This study showed that in the treatment of periarticular shoulder disorders greater pain relief and functional improvement were obtained with a dose of 40 mg triamcinolone acetonide than with a dose of 10 mg.
