Unusual case of soft palate and uvula haematoma in a patient on anticoagulant drugs.
    BMJ case reports, 2020, Dec-22, Volume: 13, Issue:12

    A 91-year-old Caucasian man on warfarin for atrial fibrillation presented in view of sudden-onset haemoptysis with fresh bleeding with clots immediately after having eaten a piping-hot traditional cheesecake (pastizz) and burning the soft-palate of his mouth. The haemoptysis had resolved by the time that the patient had arrived to hospital. On examination, a 2 cm by 2 cm dark red, solitary mass could be seen just anterior to the uvula. This was not causing any pain or discomfort to the patient. Blood results were mostly unremarkable except for a raised international normalised ratio (INR) of 3.53. The patient was administered 5 mg vitamin K orally in attempt to lower the INR level and warfarin was subsequently omitted for 7 days. He was also prescribed oral steroids on discharge. The lesion resolved in 7 days and warfarin was restarted then with no further consequences.

Less Is More: Low-dose Prothrombin Complex Concentrate Effective in Acute Care Surgery Patients.
    The American surgeon, 2015, Volume: 81, Issue:6

    Optimal dosing of prothrombin complex concentrate (PCC) has yet to be defined and varies widely due to concerns of efficacy and thrombosis. We hypothesized a dose of 15 IU/kg actual body weight of a three-factor PCC would effectively correct coagulopathy in acute care surgery patients. Retrospective review of 41 acute care surgery patients who received 15 IU/kg (± 10%) actual body weight PCC for correction of coagulopathy. Demographics, laboratory results, PCC dose, blood and plasma transfusions, and thrombotic complications were analyzed. We performed subset analyses of trauma patients and those taking warfarin. Mean age was 69 years (18-94 years). Thirty (73%) trauma patients, 8 (20%) emergency surgery patients, 2 (5%) burns, and 1 (2%) nontrauma neurosurgical patient were included. Mean PCC dose was 1305.4 IU (14.2 IU/kg actual body weight). Mean change in INR was 2.52 to 1.42 (p 0.00004). Successful correction (INR <1.5) was seen in 78 per cent. Treatment failures had a higher initial INR (4.3 vs 2.03, p 0.01). Mean plasma transfusion was 1.46 units. Mean blood transfusion was 1.61 units. Patients taking prehospital warfarin (n = 29, 71%) had higher initial INR (2.78 vs 1.92, p 0.05) and received more units of plasma (1.93 vs 0.33, p 0.01) than those not taking warfarin. No statistical differences were seen between trauma and nontrauma patients. One thrombotic event occurred. Administration of low-dose PCC, 15 IU/kg actual body weight, effectively corrects coagulopathy in acute care surgery patients regardless of warfarin use, diagnosis or plasma transfusion.

Intrathoracic and intraabdominal wall implantation of a centrifugal blood pump for circulatory assist.
    Artificial organs, 1998, Volume: 22, Issue:6

    An implantable centrifugal pump (ICP) 320 ml in volume and 830 g in weight has been developed for prolonged circulatory assist. The antithrombogenicity of the ICP is provided by a balancing hole in the center of the impeller. The watertightness and histocompatibility of the ICP are supported by its silicone ring seal and its casing of titanium and acrylic resin, respectively. The total efficiency of the ICP was 30% at a 5 L/min flow rate and a 100 mm Hg head. The heat generation, watertightness, and anatomical fitting of the ICP were assessed in an intrathoracic implantation in a goat (66 kg) and in an intraabdominal wall implantation in a goat (70 kg). Warfarin was given for anticoagulation in each experiment to keep the prothrombin time around 1.7 times that of the control. The temperatures of the pump surface, the pleura, and the room were measured every 3 h. Anatomical fitting was evaluated by pathological observation after the termination of the experiment. The ICP could run for 40 days in the chest cavity and for 11 days in the abdominal wall. The temperature of the motor remained about 1.8 degrees C higher than the reference in both experiments. The ICP was completely covered by a layer of smooth fibrous tissue. The moisture content of the seals remained normal. Although a small amount of atelectasis was found in the lingula, neither lung adhesion nor necrotic change of the chest wall was observed. The inflammation of the surrounding tissue including foreign body reaction and thermal burn was minimal. In conclusion, the ICP has satisfied in vivo testing of its watertightness, exothermicity, and anatomical fitting.
