Trichorrhexis nodosa is the most common hair shaft anomaly in which there is a chemical or physical traumatic injury, characterized by the development of node-like swelling, fragility of the shaft and paint brush effect on the side of the fracture. We report two cases of trichorrhexis nodosa in 15-year-old girl and 16-year-old-boy, occurring as results of repetitive hot-comb straightener and excessive scratching. Scanning electroscopic findings are typical to trichorrhexis nodosa.

OBJECTIVES: This study was conducted to assess the concentration of xylene exposure and exposure variability of a similar exposure group(SEG) in accordance with job title and confined space. METHOD: The study subjects included 28 workers working in the painting process in the ship-building industry. Measurement of subjects were repeated three times. Within and between-worker exposure variance components were estimated from log-transformed exposure concentrations employing a one-way nested random effects analysis of variance model. A uniformly exposed group was defined as one where the between-worker variance(sigmaB2) was less than or equal to 0.031 or bwR95 or=0.031) and the ratios of the 97.5th and 2.5th percentile workers of the log normally distributed exposures of each group of workers was more than 2. However dividing job title into confined space(in-block, out-block, in/out-block) decreased the between-worker exposure variability. CONCLUSION: This study focused on the quantitative aspects of exposure in painters in the ship-building industry. We cannot accept the assumption that SEG are uniformly exposed, as a major component of variation in exposure relates to differences in tasks or other factors. Therefore, the observational schemes can be improved by investigating jobspecific task and practice.

As an optimal quality of the restorations, there should be a least amount of seating discrepancy between the casting and abutment teeth. However, high viscosity of the cementing medium and its resulting thickness ay prevent complete seating of the restoration. The use of die spacing material provides adequate internal relief for the cementing medium. The purpose of this study is to compare the thickness of three commonly used die spacing materials. Materials and Methods : Stone plates were fabricated and divided into 12 sections to be painted with die spacers. Tru-Fit, Whip-Mix and Belle de St. Claire die spacer which are commonly used in dental practice were tested in this study. Each die spacers were painted layer by layer according to the manufacturer's recommendation. The average thickness of each die spacers were measured with light microscope(x100) and compared between them. Results and Conclusions: A silver-colored Tru-Fit die spacer has the lowest value of thickness without statistical significance comparing with a gold-colored Tru-Fit die spacer and a gray layer of Whip-Mix die spacer has the highest value of thickness without any statistical significance comparing with Belle de St. Claire die spacer. Three and four layers of Tru-Fit die spacer and two layers of Whip-Mix and Belle de St. Claire die spacers seem to be in the acceptable range of thickness of 25 to 45micrometer for optimal seating of the restorations. The standard experimental design and method should be further evaluated for more consistent and objective results.

OBJECTIVES: This study was conducted to estimate the characteristics of work-related musculoskeletal disorders and the effect of intervention program in shipyard workers. METHODS: Information on work related absences,due to musculoskeletal disorders, were collected between January, 1 2000 and August, 31 2002. Age, duration of work, job type, anatomical site of disease, cause and duration of absence due to sickness were investigated. RESULTS: From a total of 158 cases there were 108(68.4%)and 50(31.6%)cases of back, and other musculoskeletal complaints,respectively. 55(34.8%)of the cases were caused by repetitive trauma and 103(65.2%)were due to non-repetitive causes. 90(83.3%)of the back complaint cases were due to non-repetitive causes, but there was a repetitive cause of other musculoskeletal complaints in 37(74.0%)cases. Back complaints were higher in workers carrying heavy materials, but other musculoskeletal complaints were higher in painting workers.Half of workers after an absence due to sickness had returned to work within 32.0 weeks and 25.4 weeks,in the cases of back and other musculoskeletal complaints, respectively. After the application of an intervention program for musculoskeletal disease, the incidence rate of absence due to work-related musculoskeletal disorders was reduced significantly. CONCLUSION: The introduction of a musculoskeletal intervention program reduced absences due to work-related musculoskeletal disorders.
