To describe the demographic characteristics and to assess possible risk factors related to the moment of presentation at Emergency Department (ED) for pediatric humeral supracondylar fractures.

This was cross-sectional study being conducted during 5-year period from 2013 to 2017 at ED of a regional hospital in Spain. We have included all the pediatric patients (

We have included 52 pediatric patients with supracondylar fractures in this series. The mean age was 7.48 ± 2.97 years with a minimum age of 2 years and a maximum of 14 years. Among the patients there were 32 (61.54%) male and 20 (38.46%) female. Age less than 7 years found to be a protective factor against unstable fractures [OR 0.33 (0.10 - 1.02)]. Fractures presented during daytime hours showed a greater instability [OR 3.49 (1.07-11.39)]. However, the risk of presentation at nighttime was higher during the summer months (June to September).

The older is the child, the greater is the risk of suffering an unstable fracture, which increases the need for surgery. This risk is greater during the daytime. Otherwise, during the summer months, there is a higher risk of patient presentation at nighttime.

With a global rising trend in prevalence of allergic diseases, more attention has been paid to investigation of environmental risk factors. Many risk factors have so far been identified. However, novel risk factors specific to Taiwanese environment and lifestyle were still relatively unknown.
To investigate the potential effects of a number of little-known indoor risk factors on the frequency of doctor's visit for respiratory problems in context of Taiwanese environment and lifestyle.
A cross-sectional, population-based study was performed on a 861 participants around Kaohsiung area, Taiwan. Survey investigation was employed to assess the household environment and the frequency of doctor's visit for respiratory problems.
Participants who performed “daily cleaning” was shown to have a significantly (p=0.007) higher mean number of doctor's visits in comparison to those who did not. Similar observation was made for participants who periodically took out beddings (p=0.042). Age had a significant positive correlation (linear regression β 0.089) with frequency of respiratory problems.
The habit of daily cleaning was implicated as a potential indoor risk factor due to the unique nature of Taiwanese cleaning habit and close contact with cleaning supplies, which could serve as chemical irritants. Bedding takeout was predicted to be an indicator of chronic allergies rather than an actual risk factor. However, both were controversial in their role as potential indoor risk factor, and required further examination.

Childhood disintegrative disorder (CDD) is a rare autistic-like clinical condition with unknown etiology, in that previously acquired age-appropriate language, social and adaptive abilities deteriorate significantly in 2-10-year-old healthy children, although physical and neurological evaluations display no observable abnormality. Our case is a 22-year-old female born of a consanguineous marriage, with the appearance of CDD symptoms in her fifth year of age following normal mental and physical development during her initial four years of life. Without any precipitating factor, she gradually lost her language abilities, social relational skills, affectionate behavior, adaptive capacities, peer play and meaningful interest in her surrounding, friends and family members over a period of 4 years, reaching a plateau in her ninth year of age. The unique special clinical symptom in this case is a seasonal total mutism, which after the beginning of her CDD symptoms is revealing every year covering the spring. As no additional physical or psychological change accompanies her total seasonal speech loss, it cannot be attributed to any mental condition known as having a seasonal pattern. Because in the literature CDD is presented mostly as case reports with lacking of advanced research data, describing any new case is recommended to improve the knowledge about this rare condition, especially if it displays some new unusual signs, not reported till now.

Various studies have shown a seasonal pattern in suicide in the developed societies; however, this pattern is not taken into consideration in most countries including Iran. The current paper studied the seasonal pattern of committing suicide in Northern Iran. The present study was a longitudinal study with time series features. Subject included suicide attempts recorded by emergency wards of all hospitals in Mazandaran province, Iran. The variable time, in this study, was defined as each month of study years (2005 - 2011), which included 84 monthly time points. To analyze data, the Student’s independent t-test and analysis of variance (ANOVA) test were used. Of the 14,437 suicide attempts reported during the seven-year period, 5359 (37.1%) were related to males. Suicide attempts reached a peak in June (1418 cases) and November (1352 cases), but were at their lowest level in March (991 cases) (P = 0.877). The suicide seasonality range is broad in this part of Iran. Moreover, there were two noticeable suicide peaks in June and November.

This study attempted to investigate traffic accident fatalities during 2004-2009 and the effect of fuel rationing on traffic accident fatalities. This was a cross-sectional study on available data of all traffic accident fatalities in Fars Province, Iran, during 2004-2009. To identify and fit the best model, various instruments, including the autocorrelation function (ACF), partial autocorrelation function (PACF), and Akaike information criterion (AIC), were used. To determine the accuracy of the model, the residual chart was evaluated in terms of independency, normality, and stationary. Then, the best model in terms of more accurate estimation was selected and analyzed using ITMS, Minitab, and Microsoft Excel software. During 2004 to 2009, 12954 people died due to road traffic fatalities in Fars Province. Among them, 10442 (80%) were male, and mean age at death was 36 ± 20. The number of traffic accident fatalities in Fars Province reduced from 45.5 per 100000 in 2004 to 44.8 per 100000 in 2007. After petroleum rationing, the traffic accident fatality average further reduced (to 42.2 per 100000 in 2009). T here was a difference between the observed value and predicted value with two different predication methods, as the number of observed fatalities was less than the estimated numbers. Seasonal Holt-Winters and autoregressive moving average (ARMA) methods’ predications were a close estimation of the accident fatality rate after petroleum rationing, and the difference between their estimations was not considerable. Although the overall rate of fatalities reduced after petroleum rationing, variation in fatality rate did not show any association with petroleum rationing. However, decrease in fatalities had a seasonal pattern. Further decrease in road traffic fatalities requires reinforcement of educational programs as well as application of effective laws.
