We report CT and MR findings in tow cases of primary malignant melanoma of the vagina, one arising from cervicovaginal junction mimicking squamous cell carcinoma of the cervix and the other one recurring at vagina after resection. Two cases of malignant melanoma had high-attenuation on CT and high signal intensity on T1-weighted MR images and enhanced well after gadopentetate dimeglumine administration.

Purpose:
This study examined the effects of heel raise exercises combined with neuromuscular electrical stimulation (NMES) on the muscle strength and postural control ability of subjects with functional ankle instability (FAI).
Methods:
Twenty-two subjects with FAI participated in this study. They were assigned randomly to two groups: 11 each in the NMES and the sham-NMES groups. Heel raise exercise was applied, and NMES electrodes were attached to the peroneus longus muscles. The NMES group applied NMES during the heel raise exercise. NMES was applied for 20 minutes during the heel raise exercise. The heel raise exercise was performed four times a week for five weeks. The muscle strength and balance error scoring system (BESS) were measured before and after the intervention.
Results:
A comparison of before and after the intervention within the groups revealed improved muscle strength in the NMES and Sham-NMES groups, but the BESS was improved under all conditions only in the NMES group. The Sham-NMES group showed no improvement in the unstable support surface. Furthermore, when comparing the amount of change before and after the intervention between the groups, there were significant differences in the total score and unstable support in the BESS and muscle strength.
Conclusion
NMES had a positive effect on the functional activities of the functional ankle instability subjects, such as balancing on an unstable support surface during postural control and increasing muscle strength.

PURPOSE: Great progress has been made in the adjuvant treatment of colon cancer. The aim of this study was to evaluate the efficacy of postoperative adjuvant chemotherapy using the FOLFOX regimen in patients with stage III and high-risk stage II colon cancer. METHODS: Eighty-two patients who underwent a potentially curative resection for stage III or high-risk stage II colon cancer were enrolled in this retrospective study. They received FOLFOX4 or modified FOLFOX6. The primary endpoint was disease-free survival. RESULTS: During the median follow-up of 37 months (range, 21 to 61 months), 14 patients experienced disease relapse. The disease-free survival rate at 3 years was 82.9%: 84.6% for stage II and 82.6% for stage III. At the time of the analysis, 8 patients were dead from recurrence. The probability of overall survival at 5 years was 74.5%: 90% for stage II and 74.6% for stage III. Grade 3 or 4 hematologic adverse events included neutropenia (40.2%), anemia (2.4%), and thrombocytopenia (1.2%). Gastrointestinal toxicities included grade 3 or 4 nausea (4.9%) and stomatitis (2.4%). Peripheral sensory neuropathy was observed in 81.7% of the patients during treatment. Of the 11 patients (13.4%) who had grade 3 peripheral sensory neuropathy during treatment, grade 3 symptoms were persistent in 3 patients with gait disturbance at the time of analysis. No treatment-related deaths were recorded. CONCLUSION: Postoperative chemotherapy using the FOLFOX regimen, oxaliplatin in combination with 5-fluorouracil and leucovorin, is effective and tolerable in patients with stage III and high-risk stage II colon cancer.

Purpose:
To evaluate the long-term clinical outcomes of vitrectomy with internal limiting membrane (ILM) removal for patients with macular hole retinal detachment (MHRD).
Methods:
We retrospectively reviewed the medical records of patients with MHRD who underwent vitrectomy with ILM removal. The incidence of retinal re-attachment and MH closure at 1 month were calculated. Factors associated with RD recurrence were investigated. Visual acuity before surgery was compared to that at the final visit.
Results:
Forty-two eyes were included; the mean follow-up period was 38.5 ± 19.1 months. Twenty-three eyes received gas injections and 19 silicone oil injections. Retinal re-attachment occurred in 41 (97.6%). Type 1 closure was noted in 21 eyes (51.2%) and type 2 in 20 (48.8%). Recurrent RD was noted in five eyes (14.6%) within 3 months of initial surgery. Type 2 closure was a risk factor for recurrence (p = 0.021). The logarithm of the minimum angle of resolution best-corrected visual acuity improved significantly from 1.79 ± 0.79 before surgery to 1.30 ± 0.75 after surgery (p < 0.001).
Conclusions
Retinal re-attachment was noted in most patients and the MH closed in approximately half of all patients after vitrectomy with ILM removal to treat MHRD. RD did not recur later than 3 months after initial surgery. Further efforts to increase the rate of type 1 closure are required.

PURPOSE: To evaluate the correlation between serum methotrexate (MTX) peak levels and clinical outcome of osteosarcoma, as well as to determine the correlation of these levels with the histologic response and event-free survival (EFS). METHODS: To maintain the homogeneity of the study population, we selected 52 patients with localized extremity osteosarcoma who had received two cycles of neoadjuvant chemotherapy consisting of high-dose (HD) MTX (12 g/m2), cisplatin (100 mg/m2), and doxorubicin (60 mg/m2). RESULTS: Totally, 204 courses of HD MTX were administered. The serial MTX levels (mean+/-SE) at 4 h (peak), 24 h, 48 h, and 72 h were 1292.14+/-12.83 micrometer, 9.29+/-3.89 micrometer, 1.73+/-1.37 micrometer, and 0.58+/-0.44 micrometer, respectively. The peak MTX serum level was 1292.14+/-12.83 micrometer. Neither the continuous average MTX peak level nor the dichotomized MTX peak level was related to the histologic response. However, the patients with a high 24-h MTX level (3.4 micrometer) had a poor histologic response (P=0.044). An inverse relationship was observed between MTX levels and survival: the EFS was better in the patients with a mean MTX peak level of less than 1,400 micrometer (P=0.002) and mean 24-h MTX level of less than 3.4 micrometer (P=0.011). CONCLUSION: The inverse correlation between the MTX level and the outcome is an unexpected finding. Further study on the pharmacokinetics of MTX is required to substantiate our findings and elucidate the mechanism involved.

Cystic lesions or progressive cystic changes in adenocarcinoma of the lung have rarely been reported. We report a case of lung adenocarcinoma that progressed from ground-glass opacities (GGOs) and consolidations or nodules to extensive cystic lesions during 12 months in a young adult patient. A 29-year-old male was initially diagnosed with primary lung adenocarcinoma by transbronchial lung biopsy of the right lower lobe and lung to lung metastasis in both lungs according to imaging findings. The initial chest computed tomography (CT) scans showed multifocal GGOs, consolidations, and nodules in both lungs. Despite treatment with palliative chemotherapy, the patient's follow-up CT scans showed multiple, cystic changes in both lungs and that the lesions had progressed more extensively. He died of hypoxic respiratory failure one year after his diagnosis.

Although, gastric cancer is quite common in Korea, the treatment outcome is relatively favorable compared to that of Western countries. However, there is no Korean multidisciplinary guideline for gastric cancer and thus, a guideline adequate for domestic circumstances is required. Experts from related societies developed 22 recommendation statements for the diagnosis (n=9) and treatment (n=13) based on relevant key questions. Evidence levels based on systematic review of literatures were classified as five levels from A to E, and recommendation grades were classified as either strong or weak. The topics of this guideline cover diagnostic modalities (endoscopy, endoscopic ultrasound, radiologic diagnosis), treatment modalities (surgery, therapeutic endoscopy, chemotherapy, radiotherapy) and pathologic evaluation. External review of the guideline was conducted at the finalization phase.
