The interrelations of radiologic findings and mechanical ventilation in community acquired pneumonia patients admitted to the intensive care unit: a multicentre retrospective study

BACKGROUND: We evaluated patients admitted to the intensive care units with the diagnosis of community acquired pneumonia (CAP) regarding initial radiographic findings. METHODS: A multicenter retrospective study was held. Chest x ray (CXR) and computerized tomography (CT) findings and also their associations with the need of ventilator support were evaluated. RESULTS: A total of 388 patients were enrolled. Consolidation was the main finding on CXR (89%) and CT (80%) examinations. Of all, 45% had multi-lobar involvement. Bilateral involvement was found in 40% and 44% on CXR and CT respectively. Abscesses and cavitations were rarely found. The highest correlation between CT and CXR findings was observed for interstitial involvement. More than 80% of patients needed ventilator support. Noninvasive mechanical ventilation (NIV) requirement was seen to be more common in those with multi-lobar involvement on CXR as 2.4-fold and consolidation on CT as 47-fold compared with those who do not have these findings. Invasive mechanical ventilation (IMV) need increased 8-fold in patients with multi-lobar involvement on CT. CONCLUSION: CXR and CT findings correlate up to a limit in terms of interstitial involvement but not in high percentages in other findings. CAP patients who are admitted to the ICU are severe cases frequently requiring ventilator support. Initial CT and CXR findings may indicate the need for ventilator support, but the assumed ongoing real practice is important and the value of radiologic evaluation beyond clinical findings to predict the mechanical ventilation need is subject for further evaluation with large patient series

Styropor Kullanılarak Elde Edilen Hafif Betonların Fiziksel Özelliklerinin Deneysel Olarak Araştırılması

Bu çalışmada; beton karışımına styropor ilave edilerek elde edilen hafif betonun fiziksel özellikleri deneysel olarak araştırılmıştır. Araştırma yapılan numuneler, katkısız ağırlığından %10, 20, 30 ve % 40 oranlarında azalma oluşturacak miktarlarda styropor ilave edilerek hazırlanmıştır. Deneyler ilgili Türk Standartları gözetilerek yapılmıştır. Araştırılan fiziksel özellikler; donma-çözülme dayanımı, su emme, boşluk oranı ve birim ağırlık oranının belirlenmesidir. Numunelerdeki styropor oranının artması ile malzemenin birim ağırlığında azalma olurken, su emme ve boşluk oranında artma olmuştur. Donma-çözülme neticesinde numunelerde çatlamalar ve az miktarda da parçalanmalar olmuştur

Protective effect of celtis tournefortii against copper-induced toxicity in rat liver

WOS:000654628800012This study aimed to investigate the antioxidant and hepatoprotective effects of Celtis tournefortii fruit extract (Ct) against copper-induced liver damage in rats. Thirty-two Wistar Albino rats were divided into four equal groups (n = 8): Control, Copper (Cu), Copper + C. tournefortii (Cu+Ct), and C. tournefortii (Ct). Superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activities, glutathione (GSH) concentration, malondialdehyde (MDA), total antioxidant status (TAS) and total oxidant status (TOS) were analysed in the liver tissues. Liver histopathology was also evaluated. Alanine aminotransferase and lactate dehydrogenase significantly decreased in the Cu+Ct group compared with the Cu group. Oxidative stress parameters MDA and TOS significantly increased with copper administration, whereas they decreased with C. tournefortii co-treatment compared to Cu group. GSH concentration and TAS showed significant decreases with copper administration. Celtis tournefortii co-supplementation with copper significantly enhanced antioxidant parameters such as TAS, SOD, and GPx. Celtis tournefortii remarkably attenuated degenerative and necrotic changes caused by the oral exposure of copper in the liver tissue of rats. Celtis tournefortii may provide amelioration of the antioxidant status and moderation of severity of liver damage against copper toxicity. The therapeutic use of C. tournefortii may exhibit protective effects in liver injury treatment.This research was supported by the Van Yuzuncu Yil University Scientific Research Projects Foundation (grant number FYL-2016-5479)

Epidermal cyst in an unusual site: A case report

Introduction: Epidermoid cysts can occur in a variety of locations including face, trunk, neck, extremities and scalp. Up to now, those vulvar epidermal cysts reported in the literature were localized on the labia majora and the clitoris. This is the first case of epidermal cyst reported on the labia minora. Presentation of case: A 47-year-old, multiparous woman presented with a history of a palpable vulvar mass, without pain but causing difficulty in walking. The large mass was 6 cm in diameter and located in the left labium minus. The labial mass was surgically removed. The final pathologic diagnosis was a vulvar epidermoid cyst. The patient was discharged from hospital without any complications. Discussion: Total surgical excision of the mass is more appropriate for definitive histopathological diagnosis and for the prevention of future development of complications. MRI is very important in the localization of the mass and relationship with other tissues regarding treatment planning of larger vulvar masses. Conclusion: Epidermal cysts should be considered in the differential diagnosis of a vulvar mass
