PURPOSE: We analyzed the oncological outcome and prognostic factor of the chondrosarcoma arising from benign bone tumor due to malignant transformation. MATERIALS AND METHODS: From April 1986 to April 2009, 18 cases were considered eligible. We analyzed retrospectively the patient's characteristics and prognostic factors that affect to the local recurrence and distant metastasis. RESULTS: As classified by primary benign bone tumor, 4 cases were solitary osteochondroma, 11 cases were multiple osteochondromatosis and 3 cases were multiple enchondromatosis. The mean follow-up period was 85 months. The 5-year disease free survival rate of 18 patients was 85.9%. Their overall MSTS score was 25.2 (84%). There were local recurrence in 3 cases and no distant metastasis. We found that tumor location and surgical margin affected to the prognosis significantly. CONCLUSION: In secondary chondrosarcoma patients, the prognosis was good relatively and tumor location and surgical margin are important prognosis factor.

The immature teratoma is extremely rare tumor consisting of mature tissues and immature embryonal tissues. The immature teratoma in children occurs more frequently at the sacrococcygeal bone, testis and ovary. Only 9.5 percent of immature teratomas occur in retroperitoneum. Often the presenting manifestation is asymptomatic with increasing abdominal distention or mass discovered during physical examination. We report a case of congenital retroperitoneal immature teratoma in 3-week-old boy who was treated by surgical excision.

During the arthroscopic surgery of the shoulder, there was extravasation of fluid into the surrounding soft tissue due to the use of pressure pump irrigator. Clinically, the shoulder region became tense and intramuscular pressure of the deltoid could be elevated. To analyze the change of the intramuscular pressure of the deltoid and the efficiency of cryotherapy in the shoulder arthroscopy with pressure pump, we studied 35 consecutive patients who underwent various arthroscopic shoulder procedures at the Dankook University Hospital. We monitored intramuscular pressure using spinal needle connected to the patient monitoring system during arthroscopic procedures and postoperative period until return to preoperative pressure level. Twenty-seven patients were fitted with a cryotherapy. device in the operating room, and 8 were not according to the patient opinions. We evaluated the effect of cryotherapy with visual analog scales and amounts of analgisics for 3 days postoperatively. The results were followed; 1. Intraoperative highest intramuscular deltoid pressure was 293mmHg (average 169+/-68mmHg, 71293mmHg). 2. Immediate postoperative deltoid pressure was average 58.3+/-28.1mmHg (24-145mmHg). 3. Average time that the pressure had returned to the preoperative level was 114.3+/-38.6 minutes (p<0.05). There were no statistically significant between two groups, 113.9+/-41.1 min in the cryotherapy group and 115.7+/-32.6 min in the non-cryotherapy group. 4. Shoulder pain was less in the cryotherapy cases until second postoperative day. In conclusion, arthroscopic surgery of the shoulder can be performed with minimal complication in spite of high intramuscular deltoid pressure. More than 60 minutes may be needed for returning to normal intramuscular deltoid pressure. Cryotherapy is eftective in the pain relief but cannot minimize swelling postoperatively.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Osmidrosis axillae is a distressing problem characterized by foul odor at the axillae due to excessive apocrine sweat gland secretion. We introduce a new non-surgical method using a specially insulated needle and high frequency electrocoagulator. From September 2001 to January 2005, 52 patients were treated with this procedure for osmidrosis axillae. In authors' procedure, insulated needle which was designed to protect skin and dermal layer was inserted into the deep dermis of axilla area and apocrine sweat glands were removed by electrocoagulation. Fifty two patients were evaluated more than 6 months after surgery. Among these patients, 48 patients received secondary coagulation procedure. After second operation, all patients were satisfied with postoperation results. We conclude that our method has several advantages such as 1) short operation time, 2) no necessity of postoperative immobilization of shoulder joints, 3) no need of hospitalization, 4) minimal scarring and no bleeding, 5) prevention of skin necrosis, 6) a safer operative method for recurred cases as a secondary method.

BACKGROUND: Group B streptococcus (Streptococcus agalactiae, GBS) was reported as a major cause of neonatal infection and death. To prevent vertical transmission, CDC recommended that all women in week 35-37 of pregnancy should receive the GBS colonization test. We conducted a systematic review and meta-analysis to evaluate diagnostic accuracy and detection rate of real-time PCR for GBS in pregnant women. METHODS: The literature review for GBS using real-time PCR was done including KoreaMed, Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library on November 3, 2015. 443 articles were collected. Two authors select articles and evaluated the quality of studies using Scottish Intercollegiate Guidelines Network tool independently. RESULTS: Diagnostic accuracy of the real-time PCR was assessed by meta-analysis through 34 articles (13,516 for real-time PCR, 1,815 for culture and other comparison test). The GBS colonization was assessed through 34 articles, which reported varying values of 2.0–69.2% using real-time PCR. The real-time PCR for GBS was shown to have overall sensitivity of 0.93 (95% CI 0.92–0.94, I2=86.3%), overall specificity of 0.96 (95% CI 0.96–0.96, I2=90.2%), SROC AUC of 0.99. CONCLUSION: Real-time PCR is an effective test for detecting GBS colonization in pregnant women, resulted in preventing the infection in a new born baby.

OBJECTIVE: To explore the effect of visual and haptic vertical stimulation on standing balance in post-stroke patients. METHODS: Twenty-five post-stroke patients were recruited. We measured left/right standing pressure differences and the center of pressure (COP) parameters for each patient under three different conditions: no stimulation, visual, and haptic stimulated conditions. First, patients stood on a posturography platform with their eyes blindfolded. After a rest period, the patients stood on the same platform with their eyes fixed to a 1.5-m luminous rod, which was placed at a vertical position in front of the patients. After another rest period, the patients again stood touching a vertically placed long rod in their non-hemiplegic hand with their eyes blindfolded. We collected the signals from the feet in each condition and obtained the balance indices. RESULTS: Compared with the no stimulation condition, significant improvements were observed for most of the COP parameters including COP area, length, and velocity for both the visual and haptic vertical stimulation conditions (p<0.01). Additionally, when we compared visual and haptic vertical stimulation, visual vertical stimulation was superior to haptic stimulation for all COP parameters (p<0.01). Left/right standing pressure differences, increased, although patients bore more weight on their paretic side when vertical stimulation was applied (p>0.01). CONCLUSION: Both visual and haptic vertical stimulation improved standing steadiness of post-stroke patients. Notably, visual vertical stimulation was more effective than haptic stimulation.

We report a 77-year-old woman with bilateral pons infarction who presented with severe trismus, which was responsive to botulinum toxin-A injection. She was unable to open her mouth and showed anterior displacement of her temporo-mandibular (TM) joint on MRI findings. She was fed via nasogastric tube because of mouth opening limitation. There was no improvement of her mouth opening after range of motion exercise. She underwent closed reduction of the TM joints under general anesthesia but there was no significant improvement. Electromyography studies revealed continuous muscle activities on masseter and temporalis muscles during mouth opening. Botulinum toxin-A (Botox(R)) was injected into both the masseter and left temporalis muscles under ultrasonographic guidance. There was some improvement in mouth opening at post-injection 5 days. The inter-incisal distance improved gradually, and she could start oral feeding after 18 days. She could maintain an inter-incisal distance of 1.8 cm with favorable response during post-injection 4 months.
