BACKGROUND AND OBJECTIVE: It is not uncommon to encounter labyrinthine fistulae during cholesteatoma surgeries. The aim of this study is to evaluate the postoperative changes of labyrinthine fistulae after removal of matrix and closure by bone pate with fibrin glue. MATERIALS AND METHODS: We evaluated 25 patients who had operatively closed labyrinthine fistulae of horizontal semicircular canal in the chronic otitis media with cholesteatoma using CT. Seven human temporal bones with labyrinthine fistulae were studied. The fistulae were closed with bone pate using fibrin glue and fascia. RESULTS: Postoperative CTs show that, in all cases, the layer closing the fistulae was indistinguishable from the surrounding bony otic capsule. CONCLUSIONS: Canal down mastoidectomy with closure of fistulae using bone pate with fascia were effective for new bone formation at the fistulae site.

BACKGROUND AND OBJECTIVE: During the last decade, the surgical use of alloplasts has become more and more widespread among otologists. But extrusion has been the general problem associated in using alloplasts. This study analyzes the change of' surface and microcomponent of the extruded Polycel prosthesis following a long-term middle ear implantation. MATERIALS AND METHODS: Nine extruded Polycel prosthesis were investigated using scanning electronmicroscopy (SEM) and energy dispersive spectrometer (EDS). RESULTS: They all showed a severe resorption of fibrous encapsulation and partial resorption of the shaft which faced stapes and footplate. The carbon component decreased and nitrogen and oxide increased more than the original Polycel due to microdegradation. CONCLUSION: Consistent microdegradation and resorption may be one of the factors causing extrusion of Polycel.

Cystitis glandularis is a benign metaplastic proliferative lesion of the urinary bladder which usually occurs in the setting of chronic irritation and infection or in some cases as a congenital process. Sometimes it presents as a tumor mass-like florid lesion, grossly mimicking malignancy. We report a case of 59-year-old man with multiple mass lesions around the trigone and the neck portion, which suggested the possibility of malignancy in clinical and radiological evaluations. Final diagnosis was confirmed by transurethral resection. The surface urothelial lining was intact. The submucosa showed von Brunn's nests, cystitis glandularis and cystitis cystica in the edematous lamina propria. There were numerous glands lined by tall columnar, mucin producing epithelium without atypia, conforming to the appearance of the intestinal variant of cystitis glandularis. The cystitis glandularis may mimic a neoplasm on gross evaluation. The intestinal variant of cystitis glandularis is particularly likely to be problematic when florid.

PURPOSE: Drug-induced non-cardiogenic pulmonary edema has been reported on in a drug case series. For most of the agents that cause pulmonary edema, the pathogenic mechanisms that are responsible for the pulmonary edema remain unknown. We report here on the cases of suspected drug-induced pulmonary edema and we analyze the clinical characteristics. METHODS: We reviewed the medical records of 1,345 patients who had drug adverse effects and drug poisoning from January 2005 to July 2010, and 480 of these patients were admitted to the EM Department. Among them, 17 patients developed abnormal chest radiological findings and they were analyzed for any clinical characteristics, the initial symptoms, securing the airway and the clinical results. RESULTS: Seventeen patients out of 480 (3.54%) developed drug-induced abnormal chest radiographic pulmonary edema; they displayed initial symptoms that included mental change (41.2%), dyspnea (17.6%), vomiting (11.8%), etc, and some displayed no symptoms at all (11.8%). Only 3 patients out of the 11 who died or had severe pulmonary edema were able to obtain an advanced airway prior to their arrival to the EM Department. Clinical recovery was generally rapid and this was mostly completed within 6 hours. The mortality rate was 11.8% (2 of 17 patients), and the causative drugs were found to be propofol (35.3%, 6 of 17 patients), multiple drugs (41.2% or 7 out of 17) and one patient each with ephedrine, ethylene glycol, doxylamine and an unknown drug, respectively. CONCLUSION: Drug-induced pulmonary edema and deaths are not uncommon, and recovery is typically rapid with few long-term sequelae when drug administration is discontinued. Oxygen therapy and securing the airway must be performed during transportation for patients with pulmonary edema.

Objectives: The prevalence of cumulative trauma disorders of upper extremities mons watch assembly workers in small-scaled industry was studied. Methods: In 83 workers at five watch assembly factories, symptoms and psychosocial questionnaire, ergonomic Interview, physical examination were conducted. Results: Prevalence of self-reported symptoms was 54.2% and neck 34.9%, wrist/hand 31.3%, shoulder 30.1%, elbow/arm 18.0% by anatomical site. Prevalence of cumulative trauma disorders was 45.8%. Most common disease was myofascial pain syndrome (31.3%). The other diseases were De Quervain disease (9.6%), tenosynovitis/tendinitis at wrist/hand (9.6%), bicipital tendinitis(6.0%), fat. epicondylitis(4.8%), meIn. epicondylitis(2.4%), and cervical disc disease(2.4%). As result of ergonomic interview, repetitiveness was 79(98.8%). There were no differences in the prevalence of self-reported symptoms and cumulative trauma disorders for age, sex, marital status, duration of work In the study, The significant factors of cumulative trauma disorders were occupational task and psychosocial stress in the study. The prevalence of cumulative trauma disorders in high strain group was hlgher (68.4%) than other three groups. The prevalence of self-reported symptoms and cumulative trauma disorders in assembly task was higher (70.0%, 64.0%) than other two tasks. Conclusions: Prevalence of self-reported symptoms was 54.2%, prevalence of cumulative trauma disorders was 45.8% in watch assembly workers. In this study, factor related to self-reported symptoms was occupational task and factors relaxed to cumulative trauma disorders were occupational task and psychosocial stress. This results suggest that differences of ergonomics and environment in occupational task cause differences of prevalence of self-reported symptoms and cumulatlve trauma disorders.

Tympanic membrane (TM) perforation is common. Acute persistent or chronic TM perforations require surgical interventions such as myringoplasty or tympanoplasty. Current strategies of tissue engineering are focused on the regeneration of TM perforation instead of surgical interventions. To regenerate TM tissue or restore acoustic-mechanical property, bioscaffold or growth factors are necessary that will act as a temporary matrix for cell proliferation and extracellular matrix deposition, with subsequent ingrowths. In recent years, various scaffolds, biomolecules have been used for TM tissue engineering. Cells in combination with supportive scaffolds have rarely reported. TM regeneration by tissue engineering approach may be considered the greatest advances in otology. This review examines the current evidence for their use and the limitations of knowledge.
