Defective fibrinolytic activity is often a contributory factor in deep venous thrombosis. A family with a high incidence of venous thrombosis in association with such a defect is presented. Of 13 family members who had had thrombosis, 12 showed a defective capacity to release fibrinolytic activity from vessel wall after venous occlusion and/or infusion of DDAVP, a vasopressin derivative. The fibrinolytic activator activity of the vessel wall was normal in all cases. This seems to be the first family in which there is evidence of an inherited abnormal fibrinolytic activity.

We describe two families with heterozygous plasminogen deficiency. In the first the patient was a 27 year-old female who suffered an acute episode of ischemic cerebrovascular disease affecting the left temporal lobe documented by arteriographic, gammagraphic and CAT studies. She had no family history of thrombotic conditions. In the other family the propositus was a 31 year-old man with spontaneous deep venous thrombosis in the left leg. His father was also symptomatic, with a history of recurrent thrombotic complications after predisposing factors, that included multiple venous thrombosis and a pulmonary embolism. Laboratory data showed normal hemostasis test results. Antigenic and functional levels of protein C, protein S and antithrombin III were within normal limits. The only abnormality found was decreased plasminogen activity in plasma; antigenic and functional levels were reduced to about half-normal levels. In both cases crossed immunoelectrophoresis revealed a normal migration pattern of plasminogen. Thus, we conclude that our patients were carriers of congenital hypoplasminogenemia or familial type I plasminogen deficiency, due to decreased synthesis. We also reported on fibrinolytic response to infusion of DDAVP, a synthetic analogue of the antidiuretic hormone. Fibrinolytic activity was normal in basal conditions as well as in response to DDAVP infusion.

Aa a plasma marker of an endothelial abnormality, the serum activity of angiotensin-converting enzyme (ACE) was investigated at rest and after stimulation either by local venostasis or infusion of an analogue of lysine-vasopressin (desmopressin acetate). Desmopressin acetate did not induce any significant change in ACE, in contrast to the effect of venostasis. Searching for an endothelial abnormality implicated in the genesis of deep vein thrombosis, we used the local venostasis test in patients affected by recurrent deep vein thrombosis. Patients, divided in three groups (group I, documented history of recurrent deep vein thrombosis; group II, only one deep vein thrombosis or recurrent superficial venous thrombosis; group III, history of arterial thromboembolism), and controls were screened for basal and stimulated levels of serum ACE, together with fibrinolytic activity and von Willebrand factor level. Two types of abnormalities of serum ACE activity were found: low basal level in group I, and low response to venostasis in groups I and III; group II did not differ from controls. Measures of fibrinolytic and ACE activities are not redundant because the two types of ACE abnormalities were not individually encountered in the same patients and were independent from abnormalities of the fibrinolytic system. These findings suggest that an endothelial lesion could participate in the pathogenesis of some forms of recurrent deep vein thrombosis and support interest in the measurement of serum ACE to discriminate some patients at high risk of deep vein thrombosis.

There are many common and significant medical complications of head injury. These include (1) cardiovascular problems such as hyperdynamic state, myocardial injury, and dysrhythmias; (2) respiratory changes such as neurogenic pulmonary edema, hypoxia, abnormal ventilatory patterns, pulmonary infections, and pulmonary emboli secondary to deep vein thrombosis; (3) consumption coagulopathy; (4) water and electrolyte derangements--hypo- and hypernatremia; (5) hypothalamic/pituitary dysfunction--syndrome of inappropriate secretion of antidiuretic hormone and diabetes insipidus; (6) increased general metabolism with loss of immunocompetence, respiratory compromise, and complications of decreased activity; (7) gastrointestinal difficulties, particularly stress gastritis; and (8) infectious problems including those related to contamination from open wounds and foreign bodies such as monitors.

A 52-year-old woman presented with polyuria and polydipsia. A diagnosis of central diabetes insipidus (DI) was made, which turned out to be the first sign of acute myeloid leukemia (AML). Cytogenetic analysis revealed a balanced translocation between chromosome 3 and 12 t(3;12)(q26;p12). The patient was treated with standard induction chemotherapy and vasopressin. Before consolidation chemotherapy could be administered, deep venous thrombosis was diagnosed and leukemia relapsed. Rescue chemotherapy was started. This is the first report of an association between AML with t(3;12) and DI. Its possible pathogenesis is discussed with a review of the literature.

OBJECT The purpose of this study was to describe complications associated with the endonasal, transsphenoidal approach for the treatment of adrenocorticotropic hormone (ACTH)-positive staining tumors (Cushing's disease [CD] and silent corticotroph adenomas [SCAs]) performed by 1 surgeon at a high-volume academic medical center. METHODS Medical records from Brigham and Women's Hospital were retrospectively reviewed. Selected for study were 82 patients with CD who during April 2008-April 2014 had consecutively undergone transsphenoidal resection or who had subsequent pathological confirmation of ACTH-positive tumor staining. In addition to demographic, patient, tumor, and surgery characteristics, complications were evaluated. Complications of interest included syndrome of inappropriate antidiuretic hormone secretion, diabetes insipidus (DI), CSF leakage, carotid artery injury, epistaxis, meningitis, and vision changes. RESULTS Of the 82 patients, 68 (82.9%) had CD and 14 (17.1%) had SCAs; 55 patients were female and 27 were male. Most common (n = 62 patients, 82.7%) were microadenomas, followed by macroadenomas (n = 13, 14.7%). A total of 31 (37.8%) patients underwent reoperation. Median follow-up time was 12.0 months (range 3-69 months). The most common diagnosis was ACTH-secreting (n = 68, 82.9%), followed by silent tumors/adenomas (n = 14, 17.1%). ACTH hyperplasia was found in 8 patients (9.8%). Of the 74 patients who had verified tumors, 12 (16.2%) had tumors with atypical features. The overall (CD and SCA) rate of minor complications was 35.4%; the rate of major complications was 8.5% (n = 7). All permanent morbidity was associated with DI (n = 5, 6.1%). In 16 CD patients (23.5%), transient DI developed. Transient DI was more likely to develop in CD patients who had undergone a second operation (37.9%) than in those who had undergone a first operation only (12.8%, p < 0.05). Permanent DI developed in 4 CD patients (5.9%) and 1 SCA patient (7.1%). For 1 CD patient, intraoperative carotid artery injury required endovascular sacrifice of the injured artery, but the patient remained neurologically intact. For another CD patient, aseptic meningitis developed and was treated effectively with corticosteroids. One CD patient experienced major postoperative epistaxis requiring another operative procedure to achieve hemostasis. For 2 CD patients, development of sinus mucoceles was managed conservatively. For 1 SCA patient, an abdominal wound dehisced at the fat graft site. No patients experienced postoperative CSF leakage, visual impairment, or deep vein thrombosis. CONCLUSIONS Transsphenoidal surgery is the treatment of choice for patients with CD and other ACTH-positive staining tumors. Recent advances in endoscopic technology and increasing surgeon comfort with this technology are making transsphenoidal procedures safer, faster, and more effective. Serious complications are uncommon and can be managed successfully.
