Background Treeline ecotones of Mediterranean ecoregions have been affected by the increasing intensity and severity of droughts. Even though the effect of droughts on forest dynamics has been widely documented, knowledge is relatively scarce of how extreme climate episodes affect the hydraulic structure and, therefore, the phys-iology of woody plants. The Mediterranean Andes have experienced an uninterrupted period of drought since 2010, including an extremely dry year in 2019 with approximately 80% rainfall deficit. Here, we investigated shifts in wood anatomical and physiological traits of Kageneckia angustifolia, an endemic treeline species, in response to this drought *** We evaluated the xylem plasticity of three K. angustifolia populations across their natural distribution(31–35° Sl) based on anatomical(vessel structure and distribution) and physiological(intrinsic water-use efficiency) variables in the tree rings. We focused on the period 2000–2020 that corresponds to before the megadrought(2000–2007),(ii) megadrought(2008–2018) and(iii) hyperdrought(2019–2020). The variables were annualized and analyzed by linear mixed-effects *** Our results provide insights to the anatomical and physiological mechanisms underlying the resilience of treeline forests to persistent droughts in central Chile. We found that the extreme drought in 2019–2020 triggered shifts in vessel size and frequency that increased hydraulic safety. These significant shifts in vessel traits occurred in parallel with a decrease in pit aperture area and an increase in water-use efficiency, further increasing the resilience of K. angustifolia to extreme drought *** Our results revealed coordinated shifts in vessel size and frequency and water-use efficiency in response to the megadrought, thereby reducing vulnerability to hydraulic failure. The apparent resilience of K. angustifolia to extreme droughts suggests that this adaptation to drought stress may incre

Vertebroplasy is considered an alternative and effective treatment of painful oncologic spine disease. Major complications are very rare, but with high morbidity and occur in less than 1% of patients who undergo vertebroplasty. Spinal subdural hematoma(SDH) is an extremely rare complication, usual developing within 12 h to 24 h after the procedure. We report the case of a tardive SDH in an oncologic patient who underwent VP for Myxoid liposarcoma metastasis. Trying to explain the pathogenesis, we support the hypothesis that both venous congestion of the vertebral venous plexus of the vertebral body and venous congestion due to a traumatic injury can provoke SDH. To our best knowledge, only 4 cases of spinal subdural hematoma following a transpedicular vertebroplasty have been previously described in International literature and only one of them occurred two weeks after that surgical procedures. Percutaneous verteboplasty is a wellknown treatment of pain oncologic spine disease, used to provide pain relief and improvement of quality life and is considered a simple surgical procedure, involving a low risk of complications, but related to high morbidity, such as SDH. Therefore it has to be performed by experienced and skilled surgeons, that should also recognize possible risk factors, making SDH more risky.

Burn wound infection delays wound healing, leading to varying degrees of morbidity and mortality. Various antibiotics are administered to burn patients in burn wound management. The emergence of antibiotic resistance is a menace that costs families and the country. This review seeks to expound on infections related to burn wounds, common bacteria of burn wound infections and choice of antibiotics in burns treatment. Words such as burns, wound infection, burns injury and antibiotics were put into the Google search engine. Only articles related to the subject of burns, burn wound infection and antibiotics were used to write the review. Articles obtained included case reports on burns, research articles, review articles, short notes, briefs, literatures and other articles relating to burns. We found that the choice of antibiotics in the management of burns is an issue of major concern due to the evolution of pathogens causing these infections. The challenge of antibiotic resistance still persists in burns wound management. The commonly used topical antimicrobials included silver sulphadiazine, silver nitrate solution, silver impregnated dressings and mafenide acetate. Mafenide acetate has a wide antibacterial activity and also acts against the usual wound pathogens that were identified: Pseudomonas aeruginosa and Staphylococcus aureus. The role of antibiotic resistance is of major concern. Antibiotics must be administered after culture evidence in order to reduce the chance of increasing evolution of resistant strains of bacteria.

Objective: To determine the trends in burn admissions, and aetiology, severity and mortality of patients admitted to the Burns Intensive Care Unit of the Komfo Anokye Teaching Hospital from May 2009 to April 2016 (7 years). Methods: Patients' data used in this longitudinal and retrospective study were accessed from the records of the Reconstructive Plastic Surgery and Burns Unit. Processed data were depicted in tables and figures as appropriate. Univariate and multivariate analysis and Pearson's rank correlation were used in comparing relevant groups. Data analysis was conducted using Excel version 2013 and SPSS version 17.0. Results: A total of 681 patients, with a male to female ratio of 1.1:1.0, were analysed. The average annual incidence was 97.28 with a progressive decline in incidence. Mortality rate was 24.2%. Majority of the patients were children less than 10 years (43.5%) with scalds as the main aetiology in this group. Open flame was the major aetiology of burns (49.9%). Majority of the patients spent less than 10 days on admission (67.1%). Mean total body surface area was 30.54%. There was correlation between TBSA and disposition, total body surface area and aetiology and number of days in the Burns Intensive Care Unit, total body surface area and aetiology, and aetiology and number of days in the Burns Intensive Care Unit. Conclusions: Children below 10 years were the main victims. There was a shift from scald to open flame burns in this current study. Mean total body surface area and mortality rate have increased. There is urgent need for prevention campaign of flame burn and first aid education on intensive burns.
