Three patients with an acute exacerbation of ulcerative colitis (a 40-year-old and a 31-year-old man and a 30-year-old woman) developed a protein C deficiency (serum protein C activity between 32 and 48%). In the two men the protein C deficiency was diagnosed only after the onset of severe thromboembolic complications (cavernous sinus thrombosis; pulmonary embolism) during heparin treatment. But in the woman protein C activity was measured immediately after hospital admission (in the knowledge of the first two cases) even before heparin administration was started. All three patients received treatment with sulphasalazine (3 g daily) and fluocortolone (60 mg daily), as well as full heparinization (22,500-36,000 IU daily). Protein C activity returned to normal on remission of the ulcerative colitis (in one case only after subtotal colectomy). These case reports show that acquired protein C deficiency can be reversed by rigorous treatment of the underlying disease.

A transudative pleural effusion develops when the systemic factors influencing the formation or absorption of the pleural fluid are altered. The pleural surfaces are not involved by the primary pathologic process. The diagnosis of transudative effusion is simple to establish by examining the characteristics of the pleural fluid. Transudates have all of the following three characteristics: The ratio of the pleural fluid to the serum protein is less than 0.5. The ratio of the pleural fluid to the serum LDH is less than 0.6. The pleural fluid LDH is less than two thirds the upper limit of normal for the serum LDH. Among the conditions that produce transudative pleural effusion, congestive heart failure is by far the most common. Pulmonary embolism, cirrhosis of the liver with ascites, and the nephrotic syndrome are the other common causes. Management of transudative pleural effusions involves managing the primary disease. Refractory, massive effusions can be controlled by tetracycline pleurodesis.

We report a 38-year-old man with a pure motor syndrome and IgM gammopathy leading to flaccid quadriplegia. Improvement followed treatment with dexamethasone, cyclophosphamide, and plasmapheresis, but he died of pulmonary embolism. At autopsy, he had a proximal motor axonopathy with lymphocytic infiltration of ventral roots. Proximal motor neuropathy may masquerade as motor neuron disease. The association with gammopathy and response to treatment suggest that patients with motor neuron disease should be routinely screened for serum protein abnormalities.

Hereditary protein S deficiency (HSPD) is a predisposing factor to recurrent venous thrombosis but is not currently associated with stroke. We report two cases of HSPD revealed by stroke in young adults. The first one was a 36-year-old patient whith a pure motor hemiplegia, who gradually recovered without sequelae. Total and free protein S was decreased (55 and 10%). One of his brothers died from pulmonary embolism at 20 years and a sister had low protein S level without clinical signs. The second case was a 26-year-old patient who had a right hemiplegia with aphasia due to an infarction in middle cerebral artery area. He partially recovered, but the course of the illness was complicated by deep venous thrombosis of the lower limbs and pulmonary embolism. Total and free serum protein S level was severely decreased (25 and 0%). The patient's mother and one of his sisters also had low protein S but never had clinical complications. In both case, dupplex scanning, transcranial doppler, echocardiography, serum antithrombin III and protein C were normal. Cigarette smoking was the only risk factor for arterial disease. These two cases suggest that HSPD must be investigated in young patients with stroke, even in cases of lacunar stroke.

Pulmonary tuberculosis is very prevalent in developing countries but its thrombogenic potential is a new entity. There are reports stating the relation of Deep Vein Thrombosis (DVT) with severe forms of tuberculosis but no literature is available for correlation of pulmonary tuberculosis and pulmonary embolism. We are presenting series of five patients with different forms of tuberculosis presenting with pulmonary embolism having no risk factor for hypercoagulability. Also, serum protein C, protein S, antithrombin and factor V levels were normal in all. We are highlighting an unreported phenomenon so that high suspicion, adequate prophylaxis and prompt management of pulmonary embolism can play a vital role in the survival of this subset of patients.
