Periosteal chondroma is a slow growing benign tumor with prevalence rate of less than 2% of all chondromas. This tumor is mostly observed in clavicle, ribs and humerus and only one previous case has been reported in pelvis. Here we present an unusual case of periosteal chondroma due to uncommon presentation, location and age range. Our case is a 39 year-old male diagnosed with periosteal chondroma in pelvis. He had unspecific signs and symptoms overlapping with low back pain and disk herniation. By the time of admission he had gluteal muscle atrophy and also claudication. Differentiation of periosteal chondroma from other malignant tumors are pivotal in order to prevent aggressive and inappropriate therapies. He underwent surgical procedures and periosteal chondroma was ascertained by both radiological and Histopathological evidence. 6 months after surgery, he declared no pain, he was able to walk freely. He claimed partial paresthesia but he also declared that his paresthesia has ameliorated.
  Burn injuries are a significant cause of morbidity and mortality. For patients with extensive burn injuries, mechanical ventilation (MV) is a critical management modality. However, limited data are available regarding the outcome of burn patients receiving mechanical ventilation. This study aimed to determine the outcome in terms of mortality and its associated risk factors in burn patients who required MV.
 
  A retrospective review of all consecutive burn patients, admitted to the Burn Unit and requiring mechanical ventilation at King Abdulaziz Medical City and King Abdullah Specialist Children Hospital in Riyadh, from 2016 to 2019. For each patient, demographic, clinical, and outcome variables were collected. The length of stay was calculated from the date of initiation of MV after admission into the earliest discharge date or death date. The overall mortality rate during the period of the study was also calculated.
 
  A total of 356 patients have been admitted to the Burn Unit during the study period. The median age was 18 years (IQR 4-35 years), and 67% were male. Flame burn (48%) was the most frequent type of burn, followed by scald burns (33%). Of the sample, 80 (20%) were placed on MV with a median length of stay of eight days. The APACHE-II severity score for patients who required MV was 16 (SD±6) and the mortality rate was 20%.
 
  This study reported the hospital outcomes of burn patients requiring MV. Resources should be planned to provide ultimate management plan for burn patients to reduce the mortality rate.

Consequently, it can have a negative influence on the daily lives of children and their parents. The present study aimed to evaluate the impact of complicated and uncomplicated TDI on the oral health-related quality of life (OHRQoL) of preschoolers and their families. A cross-sectional study was carried out according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. After sample calculation and application of the eligibility criteria, 76 children from public preschools (aged 2 to 5 years) with TDI were selected during a period of 5 months. TDI was diagnosed using the Dental Trauma Index and classified according to the severity as complicated or uncomplicated.  https://www.selleckchem.com/products/AZD2281(Olaparib).html  The Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) was used to determine OHRQoL. The Poisson regression model and Poisson regression model with robust estimates were calculated according to p-values 0.05) according to the type of TDI. Based on these findings, it can be concluded that severity of TDI did not influence the OHRQoL of preschoolers and their families.Cold injury remains one of the most complex and actual problems of emergency medicine. Frosting injuries are also observed in the regions with warm climate particularly in Uzbekistan able - bodies men suffer most often, 85-90% of them are admitted in the condition of alcohol intoxication. A retrospective review was performed of patients admitted to the Burn Department of the Centre of Emergency Medical Care with frostbite injury 92 individuals of 19 to 63 years of age. The data on each patient were collected including age, sex, period of injury, injuries of extremities, bacteriological investigations, along with general warming of victims, all patients were given intravenous injection of infusion spasm and to improve microcircula determination of the injury area and different general and local treatment. Treatment of these patients is very prolonged, expensive, frequently requiring crippling operations, resulting in disability.Alcohol and illicit drug use are common among burn-injured patients. Urine toxicology and alcohol screens are a part of our admission order sets and automatically ordered for all adult patients. Our objective was to determine the impact of bias in screening compliance and compare those results to patients who test positive. All adult patients admitted between January 1st, 2014 and December 31st, 2018 were eligible for inclusion. Multivariable logistic regression was used to identify potential predictors for compliance in obtaining samples for screens, and patient characteristics associated with testing positive. Four thousand nine hundred ninety-eight patients were included in the study. The biggest predictors for compliance in obtaining samples for screens were inhalation injury, intensive care unit stay, length of stay, burn size, and current smoking status. No differences in compliance with screens were seen across age, race, or ethnicity. Current smokers and patients with a history of major psychiatric illness were more likely to test positive for alcohol and illicit drugs. Non-Hispanic Black patients were more likely to test positive for illicit drugs. Male sex and pre-existing psychiatric conditions were significant predictors for compliance for alcohol screens, and, positive tests. Implicit bias based on age, race, or ethnicity played no predictive role in compliance for either screen, however, non-Hispanic Blacks were more likely to test positive for illicit drugs. More studies are needed to understand the effect of selection bias related to sample collection, and the significance of positive test results.
