BACKGROUND: The purpose of this study was to evaluate the clinical and radiographic outcomes of internal fixation with locking T-plates for osteoporotic fractures of the proximal humerus in patients aged 65 years and older. METHODS: From January 2007 through to December 2015, we recruited 47 patients aged 65 years and older with osteoporotic fractures of the proximal humerus. All fractures had been treated using open reduction and internal fixation with a locking T-plate. We classified the fractures in accordance to the Neer classification system; At the final follow-up, the indicators of clinical outcome-the range of motion of the shoulder (flexion, internal rotation, and external rotation) and the presence of postoperative complications-and the indicators of radiographic outcome-the time-to-union and the neck-shaft angle of the proximal humerus-were evaluated. The Paavolainen method was used to grade the level of radiological outcome in the patients. RESULTS: The mean flexion was 155.0° (range, 90°–180°), the mean internal rotation was T8 (range, T6–L2), and the mean external rotation was 66.8° (range, 30°–80°). Postoperative complications, such as plate impingement, screw loosening, and varus malunion were observed in five patient. We found that all patients achieved bone union, and the mean time-to-union was 13.5 weeks of the treatment. The mean neck-shaft angle was 131.4° at the 6-month follow-up. According to the Paavolainen method, “good” and “fair” radiographic results each accounted for 38 and 9 of the total patients, respectively. CONCLUSIONS: We concluded that locking T-plate fixation leads to satisfactory clinical and radiological outcomes in elderly patients with proximal humeral fractures by providing a larger surface area of contact with the fracture and a more rigid fixation.

Since the anatomy of vocal fold and physiology of phonation are introduced, many surgical techniques for vocal fold disorders has advanced. Microflap and mini-microflap surgery were designed to protect the bare surface of the operated site. However, many new techniques have been based on common sense because of the absence of an accessible animal model with a vocal ligament. Therefore, authors studied to evaluate the differences of the results between mini-microflap surgery and microdissection surgery. Thirty-four mini-microflap surgeries(17 bilateral) and twenty-eight microdissection surgeries(14 bilateral) were performed on 31 patients. Patients' subjective evaluation and videostrobolaryngoscopic examination revealed that mini-microflap surgery was better than microdissection surgery. A mini-microflap surgery, as does limited mucosal resection, was more efficacious in the treatment of vocal nodules than microdissection surgery.

Mucoceles usually occur as solitary, asymptomatic, translucent, and dome-shaped cysts containing clear viscous fluid on lower lip or oral mucosa. The authors reviewed the clinical and histopathological findings in 33 patients with mucocele and attempted to clarify the difference between the histopathologic types (retention and extravasation). The results were summarized as follows. 1. Age distribution was from 2 to 53 years and mean age was 21.4 years. Male to female ratio was 1.2:1(18 males.15 females). 2. Histopathologic type was classified. 4 cases(12.1%, mean age.17.3 years) were retention type, 19 cases(57.6%, mean age.'21.5 years) mixed type, and 10 cases(30.3 %, mean age.20.9 years) extravasation type. Among 19 mixed types, 13 cases were retention dominant and 6 cases extravasation dominant. 3. Durations from the onset to the diagnosis could be clarified in 16 cases. Those were below 1 year in 14 cases(87.5% ) and below 3 years in 16 cases all. Mean duration was 9.4 months. 4. The sites of involvement were lower lip(72.7%), tongue(24.3%), and oral mucosa(3.0%), in decreasing order of frequency. 5. The visited departments were otolaryngology(72.7%), dentistry(12.1%), plastic surgery(9,1%) and dermatology(6.1%), in decreasing order of frequency. 6. In the histopathologic observation, surface epithelium was observed in 25 cases (75.8%), cyst in 23 cases(69.7%), granlation tissue in 29 cases(87.9%), mucin in 28 cases(84.8%), surrounding salivary glands in 20 cases(60.6%) and foamy macrophages in 32 cases(97.0% ), 7. Special stains(PAS, D-PAS, and alcian blue at pH2.5 and 0.4) for the mucin were performed in 10 cases. The results were compatible with sialomucin.

BACKGROUND: Domestic violence once considered an infrequently occurring event existing only in deviant relationships, it has been more recently recognized as a widely distributed phenomenon resulting from multiple cultural, social, psycological factors. According to declining world economics, family violence rises with a simultaneous curtailment of agencies available to assist battered persons and there is increasing pressure on emergency departments to serve those who might otherwise have sought help from public agency. In Korea, we don't have any clinical data about domestic violence, and authors analysed clinical pictures of domestic violence victims who came to the emergency department of Korean University medical center. METHOD: We reviewed the victims of the domestic violence retrospectively, who visited in ED, Korean Univ. Hospital from Jan. 1996 to the Dec. 1996. We Analysed data to Age, sex, Injury severity score, location of injury, mechanism, perpetrator. RESULTS: During the study period, total 134 domestic violence victims were identified. The young, females were predominantly victimized. And married women were more commonly violated. (about 70%). ISS was relatively mild (2.491), face and head were mainly injured by punching and objects throwing. The Prevalence of domestic violence victims almost presented at Emergency department between 6:00/P.M. and 8:00 A.M.. CONCLUSION: Emergency physicians suspect domestic violence victims who injured at face and head by punching or hitted would. In these patients, we need more detail history and physical exam. And in case of repeated domestic violence, refer to neuropychatry dept and social workers with perpetratrs, and need mere concerte social programs for domestic violence.

Primary transitional cell carcinoma of the bladder was treated with prophylactic and therapeutic Intravesical thiotepa in 7 cases. In 5 cases of stage A tumor, postoperative follow up was averaged 10.8 months and 4 cases were tumor free (80%). In 2 cases of infiltrating tumor, the instillation was not effective. Thiotepa can be given safely in the 7 days post-operative period and no leukopenia and bladder irritation symptoms were occurred.
