Severe, life-threatening acute upper gastrointestinal bleeding may occasionally occur in patients receiving coumarol prophylaxis for prosthetic heart valves. These patients are exposed to two potential, serious risks: bleeding due to the severe blood loss induced by excessive anticoagulant effect or as a consequence of the cessation of anticoagulation subsequent thrombotic occlusion of the valve and loss of patency. Herein a short case report is presented. The elderly male patient had a prosthetic valve in the aortic position and also suffered from two malignant diseases: chronic lymphocytic leukaemia and a more recently developed lung cancer with metastatic spread into both lungs. The patient had a major gastrointestinal bleed, leading to a sudden fall of haematocrit (0.09), and to a collapse of peripheral circulation due to too excessive a coumarol effect (International Normalized Ratio > 8). An acute left ventricular failure developed during the early period of the emergency blood transfusion, so the correction of prothrombin time by fresh-frozen plasma (due to the large volume requirement) was not feasible. The patient received 50 microg/kg intravenous bolus of NovoSeven (recombinant active factor VII) in an almost desperate situation. The International Normalized Ratio changed to 2.1 in 30 min; bleeding had stopped immediately. There was neither evidence of disseminated intravascular coagulation (in spite of the age and underlying diseases) nor loss of valve patency or infective endocarditis during follow-up. This modest report may call attention to the potential use of recombinant active factor VII in the coumarol-induced severe bleeding episodes of prosthetic heart valve patients.

Endocarditis has been traditionally classified as infective and non-bacterial thrombotic endocarditis (NBTE). NBTE has been associated with connective tissue diseases, chronic inflammatory processes and malignancy. During the pre-echocardiography era, the diagnosis of NBTE was most commonly determined at postmortem examination. A 63-year-old female patient with transient cerebral ischemic attacks and weight loss, who subsequently presented with aortic stenosis, is reported. She was treated for infective endocarditis, but developed a clinical picture of sepsis with disseminated intravascular coagulation. Despite aortic valve replacement, she died early postoperatively. Autopsy found valvular NBTE, multiple vascular thromboses and associated metastatic adenocarcinoma of unknown primary site. NBTE associated with malignancy April clinically mimic sepsis and infective endocarditis.

A 7-year-old castrated male German Shepherd Dog was evaluated for lethargy, icterus, and sepsis. Porcupine quills had been removed from the dog's face 1 month prior to examination; progressive right forelimb lameness had developed soon after removal of the quills. Septic arthritis of the right elbow joint was diagnosed and was unresponsive to antimicrobial and anti-inflammatory treatments. At the time of referral, the dog had developed endocarditis, septicemia, and disseminated intravascular coagulation. Via ultrasonography, a foreign body consistent with a porcupine quill was detected in the medial portion of the right humeroradial joint. The dog did not respond to initial supportive treatment and died as a result of cardiac arrest. Postmortem examination confirmed the presence of a quill in the medial compartment of the right elbow joint and severe acute endocarditis with septic emboli to the kidneys and spleen. Ultrasonographic examination should be considered as a diagnostic tool when septic arthritis secondary to a foreign body is suspected in dogs.

Certain coagulation disorders can occur in patients with cancer and thromboembolic complications are frequent. We report the case of a 53-Year-old patient with metastatic adenocarcinoma of the lung treated with chemotherapy who presented several cerebral arterial thromboembolic events leading to death a few weeks after the initial diagnosis of cancer. This case illustrates the important role of certain satellite disorders related to coagulation activation: non-bacterial thrombotic endocarditis, disseminated intravascular coagulation, anti-phospholipid antibody syndrome. The role of anticancer chemotherapy as a favoring factor for thromboembolic events is also emphasized in patients with non-small-cell lung cancer.

A cerebrovascular thromboembolic event may precede the identification of cancer, and be the first clinical evidence of an underlying malignancy. The malignancy can cause either nonbacterial thrombotic endocarditis or hypercoagulable state, both of which may have clinical manifestions such as thrombotic or embolic occlusion of multiple major cerebral vessels. We present three cases with unusual cerebrovascular events. The first case is a 62-year-old woman who was admitted due to acute left limbs weakness and consciousness disturbance. Brain computed tomographic (CT) scan showed right middle cerebral artery (MCA) and posterior cerebral artery (PCA) infarctions with uncal herniation. The second case is a 44-year-old woman who was hospitalized due to acute bilateral limb weakness and consciousness disturbance. Bilateral MCA, left PCA, anterior cerebral artery (ACA) infarctions and deep vein thrombosis in the left leg were diagnosed. The third case is a 63-year-old man who developed sudden onset of right hemiplegia and consciousness disturbance. Brain CT scan showed bilateral MCA and left ACA infarction. The results of a series of examinations including biochemistry, lipid profile, carotid duplex, and transthoracic and transesophageal echocardiography were unremarkable. All patients had positive disseminated intravascular coagulation (DIC) tests with elevated D-dimers and fibrinogen degradation products (FDP). Further systemic evaluation for malignancy revealed ovarian cancer in the first patient, endometrial carcinoma in the second patient, and adenocarcinoma of lung in the third patient. They all died of the underlying malignancy. Because the hemostatic system can be altered by malignancy, intravascular coagulation abnormalities of these malignancy-related strokes may be disclosed by laboratory assays of hemostasis.

Cerebrovascular disease is common in cancer patients and often arises from mechanisms unique to malignancy. Direct tumor effects include intratumoral hemorrhage, arterial and venous sinus invasion by tumor mass or leptomeningeal infiltrates, and tumor emboli. Complications of chemotherapy, radiation therapy, and hematopoietic stem-cell transplantion for cancer can occur before, during, or years after treatment. Coagulopathic conditions involve disseminated intravascular coagulation, thrombocytopenia, nonbacterial thrombotic endocarditis, and cerebral intravascular coagulation. Finally, septic infarction from fungal or bacterial sepsis and infectious vasculitis manifest in cancer patients immunocompromised by malignancy or cancer therapy. In many cases a combination of mechanisms is causative, and both hemorrhagic and ischemic stroke can occur simultaneously. Stroke type and mechanism, as well as the stage and pathology of the neoplasm, dictate proper management and help delineate prognosis.

Mankind has a long history of body decoration and body piercing has now reached epidemic popularity within a large proportion of the population. Complications such as bleeding and local infection are common, but severe infections like septicaemia, endocarditis and transmission of hepatitis may occur. We describe a 39 year old man with genital piercing who spent 43 days hospitalized because of Foumier's gangrene with necrotizing fascitis starting in the genital tract and perineum. He developed septicaemia and disseminated intravascular coagulation. A young woman with breast implants got severe mastitis after piercing her mamills. People with immunodeficiency, heart valve abnormality and present or future artificial prosthesis or skin disease should be discouraged from piercing. Since many disorders are not diagnosed when the piercing takes place, general restriction is recommended. Medical risks and consequences of piercing, especially of mucosal surfaces and cartilage, should not be underestimated.

Ischaemic stroke in thromboembolic mechanism may be a first sign of neoplastic disease, as in the presented case of a 56-year-old woman. Progressive trombocytopenia, anaemia with reticulocytosis and schistocytes in peripheral blood smear, elevated serum LDH activity as well as coexisting myocardial infarction initially suggested Moschcowitz syndrome. However, plasma exchange did not improve her neurological status and D-dimer values increase in subsequent evaluations indicated chronic DIC. At the same time, on transesophageal echocardiography, thrombotic endocarditis was diagnosed. Screening for cancer showed high CA 125 marker and chest computed tomography revealed lung tumor, not visible on earlier chest X-ray. In further treatment she underwent palliative radiotherapy and continued low molecular weight heparin. The neoplastic process had an unfavorable course and she died after four months. The authors point out that in case of multifocal ischaemic stroke and coexistent thrombocytopenia, neoplastic hypercoagulable state and thrombotic endocarditis should be considered.

Disseminated intravascular coagulation is a pathologic syndrome with different medical disorders. Diagnosis and treatment of this syndrome is one of the difficult managements in medical science. Thromboelastogram is the only guide for early diagnosis and precise management of this syndrome. We describe a patient who developed disseminated intravascular coagulation due to endocarditis and spleen abscess. She was diagnosed by thromboelastography and treated successfully.

Venous thromboembolism (VTE) is a common occurrence in patients with cancer, and can sometimes precede the development of the clinical manifestations of cancer. The pathogenetic mechanisms of thrombosis involve a complex interaction between tumour cells and the host haemostatic system, in addition to cancer-related clinical risk factors. The risk of VTE increases in presence of distant metastases. The development of VTE in patients with cancer is a strong predictor of decreased survival. The most common medical situations that make cancer patients at a higher risk of VTE include immobilization and chemotherapy with or without adjuvant hormone therapy. Recent findings suggest that heparin-induced thrombocytopenia (HIT) and HIT-related thrombotic complications may occur in cancer patients with a higher frequency than in patients free from malignancy. Thromboembolism is a well-recognised complication of malignant disease. Clinical manifestations vary from venous thromboembolism (VTE) to disseminated intravascular coagulation, more commonly observed in patients with haematological malignancies and those with widespread metastatic cancer, to arterial embolism, more commonly observed in patients undergoing chemotherapy and in those with non-bacterial thrombotic endocarditis.
