PURPOSE: Acute traumatic peroneal tendon dislocation is relatively rare disease and their methods of treatment is controversial, that we want to assess the characters and outcomes of 8 patients with early surgical treatments. MATERIALS AND METHODS: We evaluated the results of 8 patients who can follow up more than 28 months using sex, age, side, injury sports, concomitant injuries, Eckert and Davis classifications, anatomic variants, results and complications. RESULTS: All of 8 patients was male, average age was 27, Right side was dominant (5/8), causal sports was variable. Concomitant injuries were distal tibiofibular ligament syndesmosis injury, Peroneus longus injury, lateral collateral ligament injury. On behalf of Eckert and Davis classifications 5 patients were Grade 1 and other 3 patients were Grade 2. 1 case of low lying peroneus brevis belly was found as an anatomic variants. 6 of patients shown excellent results, 2 patients were good. Post operative complications were discomfort of operation site and mild limited dorsiflexion on ankle joint. CONCLUSION: Careful history and physical exam is important for diagnosis. And surgical treatments can expect good results.

PURPOSE: Posterior tibialis tendon dysfunction (PTTD) is one of the most common causes of acquired flatfoot deformity in western countries. But it was known that they were very rare in eastern countries. So we want to report the clinical features and outcomes of 12 patients with PTTD. MATERIALS AND METHODS: We evaluated the results of 12 patients using clinical features and results from March 2000 to January 2007 and mean follow up periods is 32 months. RESULTS: Average age was 45 years, 8 of 12 patients were female, 2 patient with hypertension and 1 with rheumatoid arthritis. 5 patients were overweighted and 5 patients were obese. 4 patients has a history of last trauma. 4 patients experienced progression of flatfoot. On behalf of Johnson and Strom classifications 6 cases were grade I, 4 cases were grade II, grade III, and grade IV was 1 case, relatively. As a treatment we used tenosynovectomy for 3 cases of grade I, additional FDL transfer was done for 2 cases of grade I and 2 cases of grade II. For other 2 patients of grade II flexor digitorum longus transfer and Medial displacement calcaneal osteotomy was done. Pathologic findings of tendon showed degenerative tendinitis. Lastly conservative treatment group was 3 cases of grade I, III, IV each. Average preoperative and postoperative American Orthopedic Foot and Ankle Society's hindfoot/ankle scoreFAS score was 58 and 90. Initial and follow up AOFAS scores of the conservative group was 38 and 57, relatively. CONCLUSION: As a cause of acquired flatfoot in adult, PTTD is not a rare disease any more in Korea. To prevent the disability and progression of flatfoot, careful clinical evaluation and proper treatment is important.

PURPOSE: The concurrent regimen of docetaxel, doxorubicin, and cyclophosphamide (TAC) has been categorized as a high-risk factor for febrile neutropenia (FN). The incidence of FN was reported to be as high as 17%–26% in studies conducted in Western countries. However, these rates may vary among different ethnic groups. This study aimed to evaluate the incidence of FN and its effect on prognosis following adjuvant TAC chemotherapy in Korean patients with advanced breast cancer. METHODS: We analyzed data from 187 patients who received 6 cycles of adjuvant TAC chemotherapy between July 2005 and December 2014. No patients received long-acting granulocyte-colony stimulating factor (G-CSF) as primary prophylaxis for FN due to guidelines for cost reimbursement in Korea. The incidence rates of FN, dose reduction of TAC, relative dose intensity (RDI), relapse-free survival (RFS), and overall survival (OS) were investigated. RESULTS: A total of 102 (54.5%) patients experienced FN, especially older patients (51 years vs. 49 years, p=0.045). RDI was lower in patients with FN than in those without (96.4% vs. 99.5%, p=0.001, respectively). Death was reported in 2 patients (2.35%) without FN and in 10 patients (9.80%) with FN (hazard ratio [HR]: 6.64; 95% confidence interval [CI]: 1.28 to 34.36; p=0.024). No significant differences in RFS (p=0.235) were found using Kaplan-Meier analysis. CONCLUSION The incidence of FN was significantly higher in Korea than in Western countries, and FN had a negative impact on the patients' prognosis. Primary prophylactic G-CSF should be prioritized in Korean patients with advanced breast cancer who receive adjuvant TAC chemotherapy.

Purpose: The regimen including concurrent docetaxel, doxorubicin, and cyclophosphamide (TAC) has been categorized as an important risk factor for febrile neutropenia (FN).This comparative study examined the clinical impact of long-acting granulocyte colonystimulating factor (G-CSF) (pegfilgrastim) during adjuvant TAC chemotherapy in Korean patients with advanced breast cancer. Methods: We analyzed data from 239 patients who received 6 cycles of adjuvant TAC chemotherapy. We categorized patients into 2 groups according to the use of primary prophylactic pegfilgrastim and compared the incidence and risk of FN, hospital care costs, and survival in the 2 groups. Results: The incidence of FN decreased from 54.2% to 21.2% in all patients, after the use of pegfilgrastim. The analysis of a total of 1,432 chemotherapy cycles showed that the incidence of FN decreased from 36.1% to 9.1% after the use of pegfilgrastim. Moreover, the decrease in the incidence of FN with the use of pegfilgrastim resulted in a significant decrease in the mean duration of neutropenia (4.15 to 1.29 days), the risk of hospitalization (99.5% to 29.7%) and the mean total hospital care cost (USD 3,038 to USD 2,347). High relative dose intensity (RDI) in patients treated with pegfilgrastim than in those not treated with pegfilgrastim (99.18% vs. 93.85%) was associated with a better overall survival (p = 0.033). Conclusions The use of pegfilgrastim during adjuvant TAC chemotherapy was significantly associated with a decrease in the incidence and risk of FN, hospital care costs, and risk of death compared to the use of adjuvant TAC without primary prophylaxis.

Purpose: Treatment with 4 cycles of docetaxel and cyclophosphamide (TC) in the adjuvant setting is associated with better outcomes than treatment with doxorubicin and cyclophosphamide (AC). However, Western guidelines have indicated that TC confers a high risk (>20%) of febrile neutropenia (FN), while AC confers an intermediate risk (10%–20%) of FN. Threrefore, we evaluated the incidence of FN and the clinical utilization of pegfilgrastim prophylaxis after adjuvant TC chemotherapy. Methods: We categorized 201 patients who received adjuvant TC chemotherapy into 3 groups according to the method of prophylaxis and compared neutropenic events, other adverse events, and hospital care costs in the 3 groups. Results: The incidence of grade 4 neutropenia decreased from 93.0% in patients without prophylaxis to 82.4% in those who received secondary prophylaxis and 16.7% in those who received primary prophylaxis. Although the incidence of FN was not different between patients without prophylaxis and patients who received secondary prophylaxis (15.7% and 14.9%), none of the patients who received primary prophylaxis developed FN. Moreover, a decrease in neutropenic events resulted in a significant decrease in the mean duration of neutropenia (2.50 days to 0.08 days, P < 0.001), the risk of hospitalization (29.8% to 2.2%, P < 0.001), and the mean total hospital care cost for all chemotherapy cycles (790.80 to 486.00 US dollars, P < 0.001). Conclusion The use of pegfilgrastim prophylaxis during adjuvant TC chemotherapy is associated with significant decreases in the incidence of neutropenic events, hospitalization, and hospital care cost compared to those seen in patients without prophylaxis.
