The ultrasound images obtained using the phantom are realistic and useful for ultrasound education. This study was undertaken to analyze the characteristics and risk factors relating to fatalities and injuries caused by paragliding. The judicial examination reports and hospital documents of 82 patients traumatized in 64 accidents during 242 355 paragliding jumps between August 2004 and September 2011 were analyzed. In these accidents, 18 of the 82 patients lost their lives. In the patients with a confirmed cause of accident, most of them were involved with multiple fractures and internal organ injuries (n=8, 44.4%). We investigated the incidence of paragliding injuries, the types of the injuries, and the severity of affected anatomical regions. The findings are significant for the prevention of paragliding injuries and future research.We investigated the incidence of paragliding injuries, the types of the injuries, and the severity of affected anatomical regions.

Pakistan has been hugely struck with massive bomb explosions (car and suicide bombs) resulting in multiple casualties in the past few years. The aim of this study is to present the patterns of skeletal and soft tissue injuries and to review the outcome of the victims who presented to our hospital. This is a retrospective chart review from January 2008 to December 2012. The medical record numbers of patients were obtained from the hospital Health Information and Management Sciences (HIMS) as per the ICD-9 coding. During the study period, more than 100 suicide and implanted bomb blast attacks took place in the public proceedings, government offices, residential areas and other places of the city. Altogether 262 patients were enrolled in the study. The mean age of the patients was 31±14 years. The shrapnel inflicted wounds were present on to the upper limb in 24 patients and the lower limb in 50. Long bone fractures were the most common skeletal injuries. The fractures were complicated by penetrating fragments and nails which result in post operative infections and prolonged hospital stay.Long bone fractures were the most common skeletal injuries.

The quality of treatment for critically ill children varies widely at different hospitals. This study aimed to analyze the characteristics of mortality in a pediatric emergency department (PED) at a tertiary children's hospital in Guangzhou, China and to investigate the risk factors associated with the mortality. The mortality of pediatric patients at the hospital from 2011 to 2013 was retrospectively analyzed using descriptive statistics. Altogether 466 919 patients visited the PED during the period and 43 925 of them were admitted for further observation. In 230 deaths, the ratio of boys to girls was 1.41, and their age ranged from 2 hours to 16 years (median, 5 months). The time from admission to death ranged from 0 to 216 hours (median, 1.5 hours). https://www.selleckchem.com/products/ly333531.html There were 92 (40%) patients who died within 24 hours after admission and 104 (45.2%) patients who died on arrival. The prominent causes of the deaths were respiratory diseases, neuromuscular disorders, cardiovascular diseases, and sepsis, most of which were ascribed to severe infection. Sixty-five deaths were associated with more than one concomitant problem. The top concomitant problems were congenital malformation, low gestational age, and severe birth asphyxia. In our center, 40% of the patients in the PED died of fatal acute diseases, and pneumonia was the first leading cause of the deaths. Almost half of the deaths occurred on arrival and the rest were due to end-stage malignant diseases. This study emphasized the importance of prevention of birth deficits by reducing deaths in infants and children.In our center, 40% of the patients in the PED died of fatal acute diseases, and pneumonia was the first leading cause of the deaths.

But their mechanism has not yet been clarified. We investigated possible relationships between ischemic stroke and weather conditions including atmospheric pressure, temperature, relative humidity, and wind speed. One hundred and twenty-eight patients with ischemic stroke who had been admitted to our hospital between January 1 and December 31, 2010 were enrolled in this study. We investigated the relationship between daily cases and weather conditions the same day or 1, 2, and 3 days before stroke. A negative correlation was found between maximum wind speed and daily cases 3 days before stroke. As the relationship between daily cases and changes of weather conditions in consecutive days was evaluated, a negative correlation was found between daily cases and change of atmospheric pressure in the last 24 hours. The maximum wind speed 3 days before stroke and change of atmospheric pressure in the last 24 hours were found to increase the cases of ischemic stroke. We recommend that individuals at risk of ischemic stroke should pay more attention to preventive measures, especially on days with low maximum wind speed, on subsequent 3 days, and on days with low atmospheric pressure in the last 24 hours.The maximum wind speed 3 days before stroke and change of atmospheric pressure in the last 24 hours were found to increase the cases of ischemic stroke.

The effect of increased oxidative stress on the development of chronic obstructive pulmonary disease (COPD) is well known. One of the antioxidative systems against oxidative stress in human body is paraoxonase (PON) enzyme that protects low density lipoproteins (LDL) against oxidation. This study aimed to explore the polymorphisms on PON1, Q192R, L55M genes of patients with COPD. DNAs extraction was obtained from blood samples of 50 patients diagnosed with COPD and 50 patients as a control group who were presented to emergency clinic. Genotypes were obtained with polymerase chain reaction (PCR) and AIw I and Hsp92II restriction enzymes were used for Q192R and L55M polymorphisms, respectively. Analysis of data was done with the Chi-square test and Fisher's exact test. A statistically significant difference in Q192R polymorphism was found between the COPD patients and the control group (P=0.05). There was no statistically significant difference in L55M polymorphisms between the patient and control groups (P>0.05). Q192R polymorphism was significantly correlated with the PON1 gene and cigarette smoking; however other risk factors did not show any significant correlation with this polymorphism. Though L55M polymorphism was significantly correlated with family history and tuberculosis, there was no significant correlation with other risk factors. We believe that more studies are needed to study the correlation of L55M polymorphism with other factors.We believe that more studies are needed to study the correlation of L55M polymorphism with other factors. Because the continuity and integrity of the trachea are likely damaged to some extent after tracheostomy, the implementation of sequential ventilation has certain difficulties, and sequential invasive-noninvasive ventilation on patients after tracheostomy is less common in practice. The present study aimed to investigate the feasibility of invasive-noninvasive sequential weaning strategy in patients after tracheostomy. Fifty patients including 24 patients with withdrawal of mechanical ventilation (conventional group) and 26 patients with sequential invasive-noninvasive weaning by directly plugging of tracheostomy (sequential group) were analyzed retrospectively after appearance of pulmonary infection control (PIC) window. The analysis of arterial blood gases, ventilator-associated pneumonia (VAP) incidence, the total duration of mechanical ventilation, the success rate of weaning and total cost of hospitalization were compared between the two groups. Arterial blood gas analysis showed that the sequential weaning group was better than the conventional weaning group 1 and 24 hours after invasive ventilation. The VAP incidence was lowered, the duration of mechanical ventilation shortened, the success rate of weaning increased, and the total cost of hospitalization decreased. Sequential invasive-noninvasive ventilator weaning is feasible in patients after tracheostomy.Sequential invasive-noninvasive ventilator weaning is feasible in patients after tracheostomy. There are over 15 million children who have cardiac anomalies around the world, resulting in a significant morbidity and mortality. Early recognition and treatment can improve the outcomes and lengthen life-expectancy of these patients. The NIH and WHO have promoted guidelines for screening for congenital cardiac anomalies using ultrasound in rural environments. Our study took place in Bocas Del Toro, Panama where a mobile clinic was established for community healthcare screening and ultrasonographic evaluation by medical student volunteers and volunteer clinical faculty. This was a non-blinded, investigational study utilizing a convenience sample of pediatric patients presenting for voluntary evaluation. Seven first-year medical students were recruited for the study. These students underwent a training program for advanced cardiac ultrasound instruction, termed "Pediatric Echocardiography Cardiac Screening (PECS)". Ten patients were enrolled in the study. Nine patients had adequate images as defined by the PECS criteria and were all classified as normal cardiac pathology by the medical students, resulting in a sensitivity and specificity of 100%. A single patient was identified by medical students as having a pathologic pulmonic stenosis. This was confirmed as correct by a blinded ultrasonographer. In this pilot study, the first-year medical students were able to correctly identify pediatric cardiac anatomy and pathology in rural Panama after undergoing a 12-hour ultrasound PECS training session. We believe that with this knowledge, minimally trained practitioners can be used to screen for cardiac anomalies in rural Panama using ultrasound.In this pilot study, the first-year medical students were able to correctly identify pediatric cardiac anatomy and pathology in rural Panama after undergoing a 12-hour ultrasound PECS training session.

The inclusion of cardiopulmonary resuscitation (CPR) in formal education has been a useful approach to providing basic life support (BLS) services. However, because not all students have been able to learn directly from certified instructors, we studied the educational efficacy of the use of peer-assisted learning (PAL) to train high-school students to perform BLS services. This study consisted of 187 high-school students 68 participants served as a control group and received a 1-hour BLS training from a school nurse, and 119 were included in a PAL group and received a 1-hour CPR training from a PAL leader. Participants' BLS training was preceded by the completion of questionnaires regarding their background. Three months after the training, the participants were asked to respond to questionnaires about their willingness to perform CPR on bystander CPR and their retention of knowledge of BLS. We found no statistically significant difference between the control and PAL groups in their willingness to perform CPR on bystanders (control 55.
