Three cases of lipomas associated with heavy talc deposits are reported in local inhabitants near a fiber glass factory. Pathologic and mineralogical analysis by polarizing microscopy, scanning and transmission electron microscopy with energy dispersive X-ray analysis and X-ray diffraction of mass were done. Simultaneously, we performed an epidemiological survey and a mineralogical study of disposed fiber glass from waste site and ground water. All tumors consisted of mature fat tissue containing an abundant birefringent talc fibers and particles under polarized light. The concentrations of the fibers were 494.7, 6.7 and 50.7 million fibers per gram of dry tissue. The fibers were needlelike with rectangular fractured ends, up to 17 micrometer in length and 0.5 micrometer in diameter. EDX and X-ray diffraction analysis of the fibers showed that 71 to 100% of the fibers were magnesium silicate, talc. We also identified magnesium silicate fibers in the fiber glass from the waste site and in the ground water which were similar to talc fibers in lipomas,. We concluded that fibrous talc, a component of fiberglass waste, might be associated with the development of lipomas via unknown exposure route.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.

A 36 year old infertile was diagnosed endometrial adenocarcinoma by endometrial biopy due to vaginal bleeding. She was characterized by obesity, hirsutism and infertility. Diagnosis was confirmed endometrial adenocarcinoma(Geade I) associated with polycystic ovarian disease postoperatively. We experienced this case and so report this case with a brief review of literatures.

Mucocuaneous Lymph Node Syndrome(Kawasaki disease) is a new diseae entity that was first described by Kawasakiin 1967. It occures predominantly in children less than 5yrs old and acute febrile illness, which is mucocutaneousinvolvment associated with swelling of cervical lymph nodes. The coronary artery aneurysms have been revealed 20–30% of patients with Kawsaki disease. The authors report a case of multiple coronary artery aneurysms inKawasaki disease which was diagnosed by a coronary arteriography.

The purpose of this study was to evaluate clinical changes in graft size after treatment with strip gingival autograft in human. 57 premolar teeth in 27 patients having the following mucogingival problems were selected. The width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth were measured at the initial examination, 2, 12 and 24 weeks following the strip gingival autograft and free gingival autograft. The change of width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth according to healing process in both graft procedures was statistically analyzed by repeated measure ANOVA test and independent t-test using SPSS program. The results were as follows : 1. The change of keratinized gingiva in both graft procedures was increased significantly at 24 weeks post-op. 2. The clinical sulcus depth exhibited no marked changes throughout the entire investigation in both graft procedures. 3. No dimensional variation was seen in graft size in both graft procedures. 4. Shrinkage did not differ significantly in both graft procedures. From the day of grafting to 24 weeks after surgery the percentages of shrinkage were : strip gingival autograft 28% and free gingival autograft 29%.

This study was conducted to evaluate the health hazards and to develop diagnostic methods of glass fiber workers. We examined 40 male glass fiber workers (exposure group) and 57 male non-glass fiber workers (reference group) with a questionnaire, physical examination, chest x-ray and pathological examination in Mar, 1997. Also we examined 65 male glass fiber workers (exposure group) and 42 male non-glass fiber workers (reference group) with the same methods also we did some energy-dispersive x-ray analyses with a scanning electron microscopic examination in Sep. 1997. Most of the clinical symptoms were significantly more frequent among the exposure group than the reference group. Coughing (32.5%), itching of the nose (30.0%), irritation of eyes (27.5%), irritation of the nose (25.0%) and sputum (22.5%) were the major symptoms among the exposure group in Mar. 1997. Only itching of the nose was significantly more frequent in Sep. 1997. No cases of pneumoconiosis were observed among the groups and there were no differences in chest abnormalities between the exposure group with the reference group on both examinations. The prevalence of dermatosis among the exposure group was 20.0% (8 cases) and the cumulative prevalence was 72.5% (29 cases) in Mar. 1997. The prevalence of dermatosis among the exposure group was 23.1% (15 cases) and the cumulative prevalence was 58.5% (38 cases) in Sep. 1997. Onset of dermatosis among the exposure group was most frequent within one month after handling. The frequent sites of skin lesions were the hands and arms on both examinations. Glass fiber induced skin lesions can be diagnosed by the scotch tape method or KOH mount and then can be examined under the light, polarizing and phase-contrast microcopies. Glass fibers can be identified by some energy-dispersive x-ray analyses with a scanning electron microscopic examination.

Dextran is a macromolecular polymer of dextrose. Dextran is used as a plasma expander with reduction in blood viscosity and disruption of red cell aggregates. It also inhibits platelet aggregation and prothrombin activation. It has been reported that a hemostatic defect characterized by a prolonged bleeding time in subject receiving large amount of dextran. The present study was undertaken to observe the effect of dextran on bleeding time and platelet aggregation by increasing volume. In this study, bleeding time was checked and sampling was done at before infusion, after 5 ml/kg, 10 ml/kg and 15 ml/kg infusion of dextran in 15 patients with spinal or regional anesthesia. The results were as follows: 1) There was prolonged bleeding time by increasing volume of dextran 40, but within nonnal limit. 2) There was no platelet aggregation with 15ml/kg of dextran.

PURPOSE: Accommodation and convergence, the main factors of near vision complex on near vision associated with miosis are essential ocular movements for binocularity. Therefore, we attempted to find appropriate treatments for anomalies of accommodation and convergence. METHODS: The basic theories and anomalies of accommodation and convergence were reviewed. Various treatment modalities for anomalies of convergence were discussed and treatment guidelines were proposed. RESULTS: Anomalies of convergence were classified into convergence insufficiency, convergence insufficiency associated with accommodative insufficiency, convergence paralysis, convergence spasm, and convergence excess. Treatment was divided into non-surgical and surgical methods which include not only vision therapy and optical treatment using a prism after cycloplegic refraction, but also rectus muscle surgery. CONCLUSIONS: The choice of effective treatments according to various causes is necessary for anomalies of accommodation and convergence through complete eye examinations. Thus, not only simple refractive error measurement and glasses prescription for best corrected visual acuity are necessary, but also active treatment by fundamental ophthalmic and neurologic evaluation in hospitals.
