Dyspnea, back pain, edema, and cyanosis developed suddenly in a 23-year-old woman during the last trimester of her first pregnancy. Although she had been noticed to have the enlarged heart and exertional shortness of breath to a slight degree, she had been apparently in good condition without any significant heart murmurs. Clinically, recurrent episodes of disseminated intravascular coagulation, including pulmonary thrombosis, were thought to be superimposed to Eisenmenger syndrome associated with toxemia of pregnancy. Anticoagulant and fibrinolytic treatments were tried, but their effectiveness was limited by hemorrhagic diathesis. She died of respiratory and circulatory failure after delivery of a moribund baby. Autopsy revealed Eisenmenger complex (a defect in the membranous portion of the interventricular septum and pulmonary vascular disease) and many fresh hemmorrhages in both lungs with a lot of new and organized thrombi. Fresh thrombi were also seen in the heart, the pancreas and the kidneys. The high peripartal mortality in Eisenmenger syndrome could be attributed to pulmonary thrombosis, which may be related to DIC, as well as to peripartal changes in circulatory function.

Severe hemorrhagic diathesis caused by hemophilia A (factor VIII:C deficiency) was diagnosed in 2 related Quarter Horse colts. Clinical signs consisted of dyspnea and dysphagia attributable to cranial cervical hematoma in one colt and to intra-abdominal hemorrhage resulting in death of the second colt. Factor VIII:C deficiency, a defect of the intrinsic coagulation pathway, is suggested by results of coagulation studies--prolonged activated partial thromboplastin time, normal prothrombin time, and normal primary bleeding time. The diagnosis was confirmed by results of factor VIII:C assays. Hemophilia A is inherited as an X chromosome-linked trait.

This paper discusses causes, hemodynamics, symptoms, and signs of pulmonary embolism. Severe cases obstruct at least 60 percent of the pulmonary vascular bed. Small or moderate cases may be easily overlooked. Symptoms may be only slight chest pain or dyspnoea, fever, giddiness, or irregular heart beat. In the author's experience with 35 cases of acute massive pulmonary embolism at the Bromptom Hospital oral contraceptives were considered a predisposing factor in 5 cases (14 percent), pregnancy was a possible cause in 2 (6 percent), a recent operation in 24 (68 percent). No other recognized factor was thought to have predisposed more than a single case. Clinical features included cyanosis, collapse, sever chest pain, dyspnoea, sweating, rapid heart rate, falling blood pressure, and occasional coughing up of blood. Electrocardiograms sometimes gave helpful information. Chest x-ray was usually not helpful except to exclude other causes. Heart catheterization and pulmonary arteriography have been done to assess the extent of the embolism. Emergency surgical pulmonary embolectomy is recommended for extreme cases. Fibrinolytic agents such as streptokinase may be adequate for less severe cases who have not had a recent operation of do not suffer from a hemorrhagic disorder.

A patient who presented with dyspnea and suspected interstitial pulmonary fibrosis suffered a fatal pulmonary haemorrhage with no feasible cause for bleeding. Autopsy revealed abundant amyloid deposits in both lungs with a diffuse alveolar septal distribution pattern. Amyloid was also found in the cardiac interstitium and in many vessel walls. Considering the affected organs and the histological characteristics, the deposits were regarded as light chain-type. Amyloidosis, which is generally an uncommon disease, very rarely affects the lung predominantly. Haemorrhagic diathesis is a known complication in amyloidosis patients, although fatal haemorrhage is rare and has not yet been reported solely of pulmonary origin. This report describes an uncommon case of idiopathic systemic amyloidosis mainly manifesting in the lungs. The diagnosis was established after fatal pulmonary haemorrhage caused by vessel impairment due to additional vascular amyloid deposits.

TAFRO syndrome, a rare systemic inflammatory disease, can lead to multiorgan failure without appropriate treatment. Although thrombocytopenia is frequently seen in patients with TAFRO syndrome, little is known about its pathogenesis. Moreover, while recent studies have reported the presence of an anterior mediastinal mass in some patients, the pathological status of this remains unclear. Here, we report a case of fatal bleeding in a patient with TAFRO syndrome accompanied by an anterior mediastinal mass. A 55-year-old female was transferred to our hospital with a 2-week history of fever, epistaxis, and dyspnea. Laboratory tests revealed severe thrombocytopenia, computed tomography (CT) showed pleural effusions, and bone marrow biopsy revealed reticulin myelofibrosis. We suspected TAFRO syndrome, but the CT scan showed an anterior mediastinal mass that required a biopsy to exclude malignancy. She soon developed severe hemorrhagic diathesis and died of intracranial hemorrhage despite intensive treatment. She had multiple autoantibodies against platelets, which caused platelet destruction. An autopsy of the mediastinal mass revealed fibrous thymus tissues with infiltration by plasma cells. Our case suggests that thrombocytopenia could be attributed to antibody-mediated destruction and could be lethal. Hence, immediate treatment is imperative in cases of severe thrombocytopenia, even when accompanied by an anterior mediastinal mass.

Two pet rabbits were presented with an acute decrease in appetite and activity. Rabbit 1 showed severe hypothermia, bradycardia, arrhythmias, a heart murmur, dyspnea, occlusion of the nares with secretions, icterus, dehydration, and gaseous gastrointestinal dilation. The urine was dark yellow. Rabbit 2 was overweight, apathetic, and dehydrated; this animal presented with a heart murmur, gastric dilation, and intermittent nystagmus with dorsal strabismus in the right eye. Blood gas, electrolyte, hematology, plasma clinical biochemistry analysis, coagulation profile, plasma protein electrophoresis, urinalysis, and radiographic examinations were performed. The main shared findings were moderate thrombocytopenia, markedly decreased aspartate aminotransferase and alanine aminotransferase activities and fibrinogen concentrations, prolonged prothrombin and activated partial thromboplastin times, profoundly increased alkaline phosphatase and gamma-glutamyl transferase (GGT) activities, and high bile acid and bilirubin concentrations. Rabbit 1 also had respiratory acidosis, marked hypoglycemia, hyperphosphatemia, and a profoundly increased creatine kinase activity. Gastric dilation was observed on both radiographic exams. A low urinary pH of 5-6, marked bilirubinuria and proteinuria, and high urinary GGT levels were present in both patients. Marked icterus developed before death, which occurred within 22 and 30 hours post admission in rabbits 1 and 2, respectively. The necropsy of rabbit 1 showed a markedly accentuated hepatic lobular pattern, pulmonary hemorrhages, pericardial effusion with adhesions, peritoneal petechiae, and icteric and hemorrhagic abdominal fat. Histopathologic findings included hemorrhagic diathesis, severe centroacinar and midzonal hepatocellular necrosis, severe necrosuppurative bronchopneumonia, and moderate cardiomyocyte necrosis. A liver PCR assay was positive for Rabbit Hemorrhagic Disease Virus (RHDV) 2 (RHDV2) and negative for classic RHDV. This is the first description of the gross clinicopathologic abnormalities associated with naturally occurring RHDV2 infection in pet rabbits.
