Background: Hemoptysis occurs due to either pulmonary diseases or bronchoscopy interventions. The aim of the present study was to compare the efficacy of the endobronchial instillation of adrenaline with that of tranexamic acid. Methods: Fifty patients were randomly selected as 2 double-blinded sample groups (n=25). In these patients, bleeding could not be controlled with cold saline lavage dur...

Introduction: The primary and definitive diagnosis of meningioma is based on histological assessment; however, employing imaging methods, like Magnetic Resonance Imaging (MRI) is very helpful to describe lesion’s characteristics. Accordingly, we decided to study the effect of imaging factors, like MRI data on the volume of hemorrhage (estimated blood loss) during meningioma surgery. Methods: T...

W HEN VESSELS ARE CUT OR INJURED, platelets adhere to exposed collagen and then to each other to form aggregates called primary hemostatic plugs. These plugs stop bleeding from the small skin vessels that are cut in performing a bleeding time. Therefore, the bleeding time is a test of the ability of platelets to function normally in the first step of hemostasis. The clinical usefulness of the b...

BACKGROUND A bleeding diathesis is a common feature of Noonan syndrome, and various coagulation abnormalities have been reported. Platelet function has never been carefully investigated. METHODS The degree of bleeding diathesis in a cohort of patients with Noonan syndrome was evaluated by a validated bleeding score and investigated with coagulation and platelet function tests. If ratios of pr...

results the hemostasis time for the ferric chloride concentration group was significantly less than for the control group (p < 0.001). materials and methods in this animal model study, 60 male wistar rats were used. an incision, 2 cm long and 0.5 cm deep was made on rat skin and the hemostasis time was recorded using ferric chloride at different concentrations (5%, 10%, 15%, 25%, and 50%) and t...

Unpredictable endometrial bleeding is the major side-effect of levonorgestrel-releasing s.c. implants (Norplant), otherwise a method of choice for long-term contraception. The mechanisms responsible for bleeding are still unknown and no reliable treatment is available. Several matrix metalloproteinases (MMP) are expressed and activated in human endometrium only at menstruation and specific synt...

BACKGROUND AND AIMS The transjugular intrahepatic portosystemic shunt (TIPS) is a new therapeutic modality for variceal bleeding. In this study we compared the two year survival and rebleeding rates in cirrhotic patients treated by either variceal band ligation or TIPS for variceal bleeding. METHODS Eighty cirrhotic patients (Pugh score 7-12) with variceal bleeding were randomly allocated to ...

The place of surgery in the management of patients with bleeding into the stomach or duodenum is largely governed by two aspects of the haemorrhage: the total volume of blood lost and the rate of bleeding. Other factors which are of importance are the cause of the bleeding and the age of the patient. Severe bleeding is one of the most demanding emergencies, and the decision may need to be made ...

The template bleeding time is a measure of platelet participation in primary hemostasis. Aspirin alters platelet function through interference with prostaglandin biosynthesis. In many individuals, aspirin will consistently prolong the bleeding time. Despite this observation, normal individuals rarely develop a bleeding disorder. This prompted us to investigate the influence of technical variabl...
