Purpose: An ingrown nail is common in military trainees who are exposed to highly demanding activities. Although the matrixectomy procedure has been the main treatment modality, several drawbacks may follow after the procedure, such as infection, periostitis, and continued pain that causes a delayed return to duty. This study examined the outcomes of a simple partial nail extraction with the hypothesis that this procedure may bring an earlier return to duty, lower the perioperative complications, and produce a comparable recurrence rate. Materials and Methods: The medical records of patients who had surgical treatment for an ingrown nail in the authors' institution between April 2016 and December 2017 were reviewed retrospectively. Under the inclusion and exclusion criteria, 28 patients with a simple partial nail extraction (group A) and 29 patients with a partial nail extraction with matrixectomy (group B) were investigated. As the clinical outcome, the visual analogue scale (VAS) and satisfaction score, time to return to duty, complications, and recurrence rate were checked and compared between the groups. Results: The VAS scores of group B were significantly higher during the first (p<0.001) and second (p=0.026) follow-up week than group A. The time to return to duty was shorter in group A (7.8 days) than group B (10.1 days), and this difference was significant (p<0.001). Group B had five patients with complications, whereas group A had none (p=0.028). No differences in the recurrence rate (p=0.197) and patient satisfaction (p=0.764) were found between the groups. Conclusion: In this study, simple partial nail extraction in military trainees resulted in lower postoperative pain, lower complication rates, and earlier return to duty than the procedure with matrixectomy. Military trainees are temporarily exposed to highly demanding activities. Thus, a satisfactory outcome would be expected with simple partial nail extraction without performing a radical procedure, such as a matrixectomy.

As the demand for natural and beautiful smiles increases, the demand for anterior aesthetic treatment is increasing. Orthodontic treatment is often necessary for esthetic, healthy and natural treatment outcome. Particularly, in the case of middle-aged patients, minor tooth movement limited to anterior teeth is more effective than comprehensive orthodontic treatment which requires a long-term treatment period. Clinician who is in charge of aesthetic dentistry should have the ability to select a case that can be treated with partial orthodontic treatment and to determine the most effective treatment method. This article provides decision flowchart for case selection and choosing the best treatment modality for anterior teeth alignment.

Statment of problem : Little in known about the importance of selection of various double crowns as retainer in determining the outcome of treatment with double crown retained removable partial denture. Purpose : To obtain information about the effects and the results of this treatment modality. Material and methods : This study describes 61 double crown retained removable partial dentures worn by 51 patients from Samsung Medical Center, Seoul a time ranging between 6 and 48 months and evaluate occlusal contacts on the denture teeth, denture movement, incidence of denture relining, denture retention, fracture of dentures and abutments, hygiene, residual ridge inflammatory changes, number of lost abutment,. interruption of denture use. Results : One tenth of all the restorations were relined. Restorations in 21 arches fractured repeatedly for various reasons . There was no apparent interrelationship between fractures and the five groups. Conclusion : Good prognoses of removable partial dentures were shown in all groups(Kennedy Classes I, II, III, combination and few remaining abutment).

Objective: To evaluate whether data acquired from perfusion computed tomography (PCT) parameters can aid in the prediction of treatment outcome after palliative chemotherapy in patients with unresectable advanced gastric cancer (AGC). Materials and Methods: Twenty-one patients with unresectable AGCs, who underwent both PCT and palliative chemotherapy, were prospectively included. Treatment response was assessed according to Response Evaluation Criteria in Solid Tumors version 1.1 (i.e., patients who achieved complete or partial response were classified as responders). The relationship between tumor response and PCT parameters was evaluated using the Mann-Whitney test and receiver operating characteristic analysis. One-year survival was estimated using the Kaplan-Meier method. Results: After chemotherapy, six patients exhibited partial response and were allocated to the responder group while the remaining 15 patients were allocated to the non-responder group. Permeability surface (PS) value was shown to be significantly different between the responder and non-responder groups (51.0 mL/100 g/min vs. 23.4 mL/100 g/min, respectively; p = 0.002), whereas other PCT parameters did not demonstrate a significant difference. The area under the curve for prediction in responders was 0.911 (p = 0.004) for PS value, with a sensitivity of 100% (6/6) and specificity of 80% (12/15) at a cut-off value of 29.7 mL/100 g/min. One-year survival in nine patients with PS value > 29.7 mL/100 g/min was 66.7%, which was significantly higher than that in the 12 patients (33.3%) with PS value ≤ 29.7 mL/100 g/min (p = 0.019). Conclusion: Perfusion parameter data acquired from PCT demonstrated predictive value for treatment outcome after palliative chemotherapy, reflected by the significantly higher PS value in the responder group compared with the non-responder group.

Objective : The authors retrospectively analysed the factors affecting the favorable outcomes in the treatment of the Failed Back Surgery Syndrome(FBSS) or six years. Method : From March 1991 to December 1996, seventy-five patients were diagnosed as FBSS and its incidence was 3.4% of admitted patients with back pain in our department. We analysed the demographic data, etiologies, clinical menifestations, outcomes according to methods of operation, numbers of previous surgery, and time intervals between initial operation and final operation. Result : The most common etiology and previous surgical method of FBSS were insufficient surgery(54.7%) and partial laminectomy(53.3%). Patients were managed as followings ; Total laminectomy and spinal fusion with instrument in 41 cases(54.7%), total laminectomy without fusion in 23 cases(30.7%), and only partial laminectomy in 11 cases(14.7%). The overall treatment outcome was satisfactory in 48 cases(64%). Satisfactory results were observed in those patients who were treated by spinal fusion after complete laminectomy(34 cases), who had underwent only one operation previously(45 cases), and when the time interval between the initial operation and reoperation is shorter than 12 months(43 cases). Conclusion : The treatment outcome in FBSS was favorable in cases of the complete total laminectomy and spinal fusion with instrument, only one previous back surgery, and short time interval between initial and final operations.

Objectives: This study evaluated the clinical results of partial sublingual glandectomy accompanying the excision of ranula as new treatment modality. Materials and Methods: A total of 43 patients who were treated between 1999 and 2007 for oral or plunging ranula were reviewed. All patients were treated surgically by various methods with a total of 55 different procedures performed. Ten cases of partial sublingual glandectomy with excision of the ranula were conducted. All excised specimens were examined. We compared the clinical outcomes resulting from each treatment method. Results: The recurrence rates for marsupialization, excision of ranula, marsupialization with gauze packing, total excision of sublingual gland and ranula, and partial sublingual glandectomy with excision of ranula were 50%, 25%, 25%, 0% and 10%, respectively. Of the 10 patients treated by partial sublingual glandectomy with ranula excision, only one experienced recurrence (10%), i.e., plunging ranula. None of the ranulas contained an epithelial lining, and the excised portion of the feeding sublingual glands showed degenerative changes. Conclusion: In removal of ranulas, we found that excision of the attached sublingual gland, which removed the feeding portion and degenerative acinar cells, yielded good outcomes. Thus, as a new conservative method for treatment, we recommend partial sublingual glandectomy to accompany excision of the ranula.

Primary malignant bone tumors of the scapula are very rare, and little literature is available regarding their characteristics and outcome. We studied the clinical characteristics, and outcome of patients with primary malignant bone tumors of the scapula. From 1979 to 2008, we treated 7 patients at our institute (4 men and 3 women; chondrosarcoma 3, Ewing's sarcomas 3, Osteosarcoma 1). The mean age was 45 years (range, 5~65 years). The follow-up period was 2 - 180 months. Six patients were performed operations: total scapulectomy 3, partial scapulectomy 1, forequarter resection 1, total resection of the shoulder girdle (Tikhoff-Linberg procedure) 1. No-operative treatment was chosen for one patient with a limited life expectancy. Local recurrence occurred in one patient. Distant metastasis occurred in 3 patients. Of the 7 patients, 4 patients are died because of propagation of the disease. Three patients were alive and apparently disease-free, and these patients were evaluated for functional results with the functional evaluation system of the International Society of Limb Salvage (ISOLAS). Functional result of partial scapulectomy was excellent, however, the function after total scapulectomy or Tikhoff-Linberg procedure is severely impaired. Our study indicates reconstruction procedure needs to be reconsidered following total scapulectomy or Tikhoff-Linberg procedure.

We report five patients of esophageal injuries confirmed by clinical signs and radiological evidences. They include a partial tear and a perforation which were not noticed during the operation, a perforation which was primarily repaired during the operation, and two perforations which occurred during the reoperations for the removal of mal-positioned screws or plate. The partial tear was not repaired. The perforation which occurred during the operation was primarily sutured and didn't receive further treatment. Two perforations which occurred during the reoperations were treated by irrigation, debridement with surgical drainage, and systemic antiobiotics. One who was diagnosed later after the operation showed the poorest outcome and required longest hospital days among our series. Early detection and appropriate treatment of esophageal injury following anterior spinal surgery can only improve the prognosis by preventing secondary complications.

Forty-nine partial thickness rotator cuff tears underwent arthroscopic debridement or repair, and were followed up for a minimum of two years. Follow-up evaluations of the results were completed using a detailed functional questionnaire which was comprised of a rating of the UCLA shoulder scale and return to the previous sports activity and job. The average age of the 49 study patients was 46.5 years(range, 14 to 67 years). The patients were divided into four groups on the basis of the onset of the patient's symptoms. Thirty-five patients(72%) had partial tearing only on the articular surface, six(12%) on the bursal surface, and eight(16%) on both surfaces. Group I consisted of 21 patients with an average age of 56.7. Partial tearing in group I was attributed to the impingement syndrome. In group II, partial tearing of the rotator cuff was related to the anterior instability of the shoulder. This group included 9 patients with an average age of 27.9. In group III, all of the 8 patients were overhead athletes with an average age of 21.8. In this group, no isolated instances of significant trauma were related to the development of the shoulder pain. In group IV, 11 patients noted that a significant traumatic event preceded the onset of their pain. The average age of the patients was 34.9. Overall, 82% of the patients demonstrated satisfactory results and 18% revealed unsatisfactory results. The worst UCLA score and rate of return to the prior activity was noted in group III. In conclusion, partial thickness rotator cuff tear can be caused by subacromial impingement, instability, repetitive microtrauma, and macrotrauma. Arthroscopic debridement of partial tear of the rotator cuff provides a favorable outcome except in overhead athletes.
