At the beginning of the 19th century, gynaecological cancer, mainly cancer of the uterus and cervix was a dreadful, incurable affection. However, the popularization of the three fundamentals in surgery, anesthesia, asepsis and haemostasis, ushered the golden age of operative gynaecology. During that period distinguished surgeons/gynaecologists such as Friedrich Benjamin Osiander (1759-1822), Elias von Siebold (1775-1828) and Joseph-Claude-Anthelme Récamier (1774-1852) contributed to the development of the operative techniques, providing a therapeutic solution in gynaecological cancer...

BACKGROUND AND STUDY AIMS: Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of unknown origin that persists or recurs after an initial negative investigation. Identifying the source of OGIB represents a diagnostic challenge that is frequently focused on visualizing the small intestine. Conventional diagnostic methods, such as push enteroscopy, small-bowel follow-through, radionuclide scanning, and angiography, each exhibit inherent limitations. Double balloon enteroscopy (DBE) was designed specifically to evaluate the entire small bowel...

Exercise has been demonstrated to have considerable effects upon haemostasis, with activation dependent upon the duration and intensity of the exercise bout. In addition, markers of coagulation and fibrinolysis have been shown to possess circadian rhythms, peaking within the morning (0600-1200 h). Therefore, the time of day in which exercise is performed may influence the activation of the coagulation and fibrinolytic systems. This study aimed to examine coagulation and fibrinolytic responses to short-duration high-intensity exercise when completed at different times of the day...

Post-partum haemorrhage (PPH) remains the major cause of maternal death worldwide, with the overwhelming majority of bleeding deaths occurring in low income countries. These bleeding deaths occur due to a complex network of biological and socioeconomic factors, including changes to haemostasis and fibrinolysis during pregnancy. Tranexamic acid (TxA) has been shown to reduce death in bleeding trauma patients safely and is effective in reducing bleeding in surgical patients, however its role in PPH has been less well established...

Probucol (PB) is an hypolipidaemic drug with potential antidiabetic effects. We showed recently using in vitro studies that when PB was incorporated with stabilising lipophilic bile acids and microencapsulated using the polymer sodium alginate, the microcapsules showed good stability but poor and irregular PB release. This suggests that PB microcapsules may exhibit better release profile and hence better absorption, if more hydrophilic bile acids were used, such as ursodeoxycholic acid (UDCA). Accordingly, this study aimed to produce PB-UDCA microcapsules and examine PB absorption and antidiabetic effects in our mouse-model of insulin-resistance and diabetes (fed high-fat diet; HFD)...

Pharmacological inhibition of platelet collagen interaction is a promising therapeutic strategy to treat intra-vascular thrombosis. S007-867 is a novel synthetic inhibitor of collagen-induced platelet aggregation. It has shown better antithrombotic protection than aspirin and clopidogrel with minimal bleeding tendency in mice. The present study is aimed to systematically investigate the antithrombotic efficacy of S007-867 in comparison to aspirin and clopidogrel in vivo and to delineate its mechanism of action in vitro...

Interaction between hypoxia and coagulation is important given the increased risk of thrombotic diseases in chronically hypoxic patients who reside at sea level and in residents at high altitude. Hypoxia alters the proteome of platelets favouring a prothrombotic phenotype, but studies of activation and consumption of specific coagulation factors in hypoxic humans have yielded conflicting results. We tested blood from 63 healthy lowland volunteers acclimatizing to high altitude (5,200 m) using thromboelastometry and assays of platelet function to examine the effects of hypoxia on haemostasis...

ADAMTS13 (A D: isintegrin A: nd M: etalloprotease with a T: hromboS: pondin type-1 motif, member 13: ) and von Willebrand factor (VWF) can be considered as scale weights which control platelet adhesion during primary haemostasis. In a very uncommon condition designated thrombotic thrombocytopenic purpura (TTP), functional absence of ADAMTS13 tips the balance toward VWF-mediated platelet adhesion in the microcirculation. TTP is associated with a high mortality and arises from either a congenital or acquired autoimmune deficiency of the plasma enzyme ADAMTS13...

Background: Four novel direct oral anticoagulants (DOACs) named dabigatran, rivaroxaban, edoxaban and apixaban have been recently introduced to overcome some of the drawbacks of existing anticoagulants. They have less interactions and do not require routine monitoring. However, there is not enough scientific data about the protocol to apply in these patients on DOACs undergoing dental treatment. Thus is necessary to evaluate the potential bleeding risk of these drugs, the possibility of thromboembolic events occurring if they are withdrawn or the need to change to heparin previously...

Sarah Robertson, Mark R Miller
Air pollution is a growing public health concern of global significance. Acute and chronic exposure is known to impair cardiovascular function, exacerbate disease and increase cardiovascular mortality. Several plausible biological mechanisms have been proposed for these associations, however, at present, the pathways are incomplete. A seminal review by the American Heart Association (2010) concluded that the thrombotic effects of particulate air pollution likely contributed to their effects on cardiovascular mortality and morbidity...

Antiplatelet drugs, such as aspirin, P2Y12 antagonists, and glycoprotein (GP) IIb/IIIa inhibitors, have proved to be successful in reducing the morbidity and mortality associated with arterial thrombosis. These agents are, therefore, the cornerstone of therapy for patients with acute coronary syndromes. However, these drugs all carry an inherent risk of bleeding, which is associated with adverse cardiovascular outcomes and mortality. Thus, the potential benefits of more potent, conventional antiplatelet drugs are likely be offset by the increased risk of bleeding...

Surgeon controlled study of 200 cold/cold and 200 hot/hot tonsillectomy cases in one institution Hot/hot resulted in higher overall rates of early and late post-tonsillectomy haemorrhage and return-to-theatre when compared to cold/cold methods. Bipolar diathermy tonsillectomy resulted in a statistically significant higher rate of secondary post-tonsillectomy haemorrhage than cold-steel of nearly three times. Trainee surgeons performed better in bipolar haemostasis than cold-steel dissection with regard to post-operative morbidity...

Background: Enoxaparin, a low-molecular-weight heparin approved for prophylaxis in patients at risk for venous thromboembolism (VTE), offers several advantages compared with unfractionated heparin (UFH). Enoxaparin is primarily excreted through renal elimination and is currently not recommended in patients receiving hemodialysis (HD) due to potential increased bleeding complications. To date, there are limited safety and efficacy data supporting the use of enoxaparin in this patient population for VTE prophylaxis...

A 32-year-old multigravid patient at 21 weeks gestation presents with major concealed placental abruption and subsequent fetal demise. During an eventually failed misoprostol regime aiming for vaginal delivery she develops severe disseminated intravascular coagulopathy. Subsequent hysterotomy reveals Couvelaire uterus with major haemorrhage and requires subtotal hysterectomy for haemostasis. This case highlights the severity of the systemic response to abruption and fetal demise in utero and the multifactorial nature of its management...
