[EX Q]: Abstract: Transient global amnesia is an unusual form of the amnestic syndrome in that it is completely reversible in most patients. The etiology of transient global amnesia is poorly understood, although involvement of the medial temporal lobe is most likely. The literature suggests that once an underlying structural lesion has been ruled out, cases can be divided into three groups: patients with a past history of migraine headaches, those who have no obvious underlying precipitating factors, and those with associated neurologic deficits during a spell and risk factors for cerebrovascular disease. Patients in the first group tend to have attacks at an earlier age and to have an increased recurrence rate but, like those in the second group, have a good prognosis. Patients in the third group often have onset later in life, and as many as 10% may have a stroke or dementia. Whether or not this is a higher incidence than should be expected in persons of this age group has not been determined. Although sophisticated testing may show persistence of the memory defect, most patients eventually recover completely.

[EX Q]: Abstract: Twelve patients with intractable rheumatoid arthritis were treated with antilymphocyte globulin (ALG), prednisolone and a cytotoxic agent, usually azathioprine, and were followed for 1 year. There was a significant (p less than 0.05) improvement in the mean score for early-morning stiffness, grip strength and the severity of nodules and vasculitis at 6 weeks and 3 months when compared to the initial visit. However, in most patients, this benefit was not sustained despite continued cytotoxic and steroid therapy. A rise in the haemoglobin and fall in ESR was maintained throughout the study period.

[EX Q]: Abstract: The relationship between airway responsiveness to inhaled antigen and histamine, immunologic release of lung histamine, immunologic responsiveness of skin, and specific immunoglobulin E (IgE) antibodies were examined in 11 inbred allergic dogs immunized with extracts of ragweed and grass and 5 nonimmunized control dogs from the same colony. Airway responsiveness to antigen and histamine was characterized by the doses that increased the airflow resistance of the total respiratory system to twice the control values (ED200). Highly significant correlations were found between airway responsiveness and cutaneous responsiveness to antigen and other immunologic characteristics (e.g., IgE and histamine released from lung by inhaled antigen) in all dogs. In ragweed-sensitized dogs, there was an inverse correlation between immunologic responsiveness (reflected by the cutaneous response to antigen and histamine released from lung by inhaled antigen) and nonimmunologic responsiveness of airways (histamine ED200: r = 0.73, P less than 0.05 and r = 0.75, P less than 0.01, respectively). Antigen ED200 was also correlated with histamine release from lung after antigen inhalation (r = 0.74; P less than 0.01). We conclude that airway reactions to inhaled antigen in allergic dogs are dependent not only on immunologic factors but also on the degree of nonimmunologic airway responsiveness to histamine and that these factors are correlated inversely.
