027; 95% CI 0.263-0.923) and tracheostomy (p=0.001; 95% CI 0.112-0.545) were the independent factors supporting survival. We found that acute physiology and chronic health evaluation II score, presence of bacteremia, and enteral nutrition did not have a significant effect on mortality.
 
  Use of tracheostomy and PN in patients with LO-VAP has a positive effect on survival. Our study also points out that mortality can be high in patients with advanced age and unconsciousness.

  The 
  genus, which belongs to the Rosaceae family, is known as Lady's mantle and is commonly used in traditional medicine. This study was designed to investigate the major metabolites isolation and gastroprotective effects of 
  .
 
  Phytochemical studies were carried out using column chromatography on 
  . The gastroprotective effect of ethanol extract of this plant was tested on indomethacin-induced gastric ulcer model in rats. In addition, superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione (GSH) parameters in the stomach tissue were examined.
 
  Quercetin-3-O-glucuronide, apigenin, and catechin were isolated from aerial parts of 
  . When macroscopic ulcer index and histopathological results were analyzed, the extract at 200 mg/kg dose was found to be most effective. All doses of extract reduced MDA level and enhanced SOD activity and GSH level.
 
  The results of this study showed that 
  has significant antiulcer activity. This effect was thought to be caused by antioxidant properties of flavonoids.

  We aimed to investigate effects of different concentrations (0.5-5%) of Sodium Hypochlorite (NaOCl) solution on healthy tissues, and determine the optimal concentration that does not harm to tissue.
 
  30 tibias of 15 male Wistar albino rats were used. The tibias were randomly divided into 5 groups (Salin, 0.5%, 1%, 2.5%, and 5% NaOCl). Tibias were reamed intramedullary, and irrigated with 20 ml of saline or increasing concentrations of (0.5-5%) NaOCl. The tibias were embedded in paraffin and the sections were stained with hematoxylin-eosin. All sections were assessed for edema, acute inflammation, or necrosis according to their density, in bone marrow and soft tissues.
 
  Pairwise comparisons revealed that irrigation of tibia with saline or 0.5% NaOCl solutions was not statistically significant in terms of necrosis in the bone marrows (p=0.320). However, irrigation of rat tibia with saline caused less necrosis in the bone marrows compared to high concentrations (1%, 2.5%, and 5%) of NaOCl (saline and 1% NaOCl, p=0.017; saline and 2.5% NaOCl, p=0.0007; saline and 5% NaOCl, p=0.001).
 
  As an irrigation solution, the effects of 0.5% NaOCl are similar to those of saline in terms of edema, inflammation, and necrosis. There is a need for evaluation of necrosis for extended periods such as one week or one month by immunohistochemical methods and flow cytometry.

  The aim of this study was to investigate pediatricians' practices toward screening in Greece.
 
  The survey was conducted within a six month period in a stratified random sample of 371 pediatricians. A questionnaire with three sections was created and pilot tested. Socio-demographic characteristics associated with inappropriate screening were identified using multivariable logistic regression models and latent class analysis.
 
  A total of 294 participants completed the telephone survey (response rate 78.6%). The median number of wrong answers to questions related to pediatricians' practice towards screening recommendations was 7±1.57 with minimum 2 and maximum 11 wrong answers. Pediatricians, with less than 15 years of experience, age >50 years old or view more than eighty patients per week, have had significantly higher odds of responding wrong to more than seven questions, hence be less compliant to USPSTF screening guidelines.  https://www.selleckchem.com/products/congo-red.html  Latent class analysis has shown that female gender, age <50 years old, and work in the private sector, were associated with a poor practice towards international screening guidelines.
 
  Our survey found gaps in screening practices among a nationwide sample of Greek pediatricians. Moreover considerable variability in reported practices of screening was noted. There is a need for the development of a national childhood screening program in Greece.

  Skin wounds after elliptical removal of benign tumors, are conventially sutured linearly for closure and often result in longer and undesirable scars. We aimed to evaluate the efficiency of four quadrant embedded intradermal purse-string suture closure technique for round defects in order to obtain satisfactory cosmetic outcomes and limited scar.
 
  We analysed the features of 143 patients for whom a total of 208 four quadrant embedded purse string sutures were used to completely close their postoperative surgical defects. The location and histopathological types of the tumors removed were noted. Tumors were located in the cervicofacial region, thoracic region, back, lower and upper extremities. The patient and observer scar assessment scale (POSAS) questionairre was utilized to evaluate objective results of the ultimate scar.
 
  The defects of the lesions after excision were closed using intradermal four quadrant buried purse-string suture. The wounds showed good final healing without obvious adverse events postoperatively.
