1/10. Spared comprehension of emotional prosody in a patient with global aphasia.

    BACKGROUND: Several studies have demonstrated that patients with right hemisphere damage, when compared with left-hemisphere damaged controls, are impaired at comprehending emotional prosody. Critics of these studies, however, note that selection may have been biased because left-hemisphere-damaged subjects had good verbal comprehension. OBJECTIVE: To learn whether a subject with a large left hemisphere stroke and global aphasia could comprehend emotional prosody in spoken material. METHOD: The authors formally tested speech and language with the Western aphasia Battery and comprehension of emotional prosody and emotional facial expression with the florida affect Battery. RESULTS: The patient could not perform verbally mediated tests but demonstrated spared ability to match emotional prosody to emotional facial expressions under a variety of conditions. CONCLUSIONS: These observations further support the idea that verbal and emotional communication systems are independent and mediated by different hemispheres.

2/10. Multiple cerebral infarcts following septic shock.

    A 60-year-old female in septic shock developed neurological signs and symptoms. She had left-sided hemiparesis, left homonymous hemianopia, bimanual coordination disorder, a language dysfunction of anomic aphasic type and a non-aphasic right hemispheric communication disorder. Computer tomography demonstrated bilateral anterior and posterior watershed as well as territorial infarctions. risk factors included chronic airways limitation, cardiac failure and heavy smoking. Carotid duplex studies were normal. The mechanisms can be explained by flow changes and thrombus formation.

3/10. Aortic root abscess complicated by fistulization and intracerebral hemorrhagic infarction.

    We report an unusual case of a 12-year-old male with aortic root abscess complicated by fistulization and intracerebral hemorrhagic infarction. Transesophageal echocardiography provided exact information about the location and dimension. color-flow mapping demonstrated fistulous communication between the abscess and both the aorta and the left ventricle, causing severe diastolic regurgitation through the paravalvular leak. Pulmonary autograft aortic root replacement was performed with good result.

4/10. Recurrent cerebral infarction during anticoagulation therapy in patients with mitral valve prolapse.

    mitral valve prolapse has been associated with an increased risk of transient or lasting ischemic events. recurrence is uncommon after initiation of antiplatelet or anticoagulant therapy. In this communication we report two patients, both female, who had mitral valve prolapse as the major risk factor for cerebrovascular disease and who developed cerebral infarction despite anticoagulation. The cerebral infarctions were bilateral and extensive in one patient and led to the patient's death. In the second case, three infarctions resulted in moderate disability.

5/10. Processing of visual syntax in a globally aphasic patient.

    A globally aphasic patient was trained on a computerized visual communication system. His ability to comprehend reversible locative prepositional phrases after training was studied and compared with the performance of Broca's aphasics on a similar task. This patient's ability to generalize symbols for actions was also investigated. The results demonstrate our patient's capacity to master a formal visual syntax in the absence of natural language and illustrate how this capacity may be used successfully in a visual communication system. A problem in generalizing symbols for actions is demonstrated, suggesting that certain heuristic and cueing capabilities in the approach may be helpful.

6/10. cerebral infarction and ventricular septal defect.

    With the availability of contrast echocardiography, patent foramen ovale is frequently detected in patients with stroke, especially in those with no clear etiology and/or the young patient with stroke. Before this report, an association of stroke with ventricular septal defect had not been reported. In this communication, we describe a 38-year-old patient who developed an occipital lobe infarction and who, on investigation, was found to have a ventricular septal defect. Other investigations, which included four-vessel cerebral angiography, collagen disease workup, and coagulation profile, were all normal. We believe this case further extends the spectrum of cerebral ischemic events that may occur with intracardiac shunts.

7/10. Treatment of chronic global aphasia with a nonverbal communication system.

    Four chronic global aphasics were treated with Blissymbols (C. K. Bliss, 1965, Semantography-Blissymbolics, Sydney: Semantography Pub.). As soon as possible the therapeutic communication was based solely on the use of the symbols. Three patients seemed to benefit from therapy. In one case therapy had to be discontinued because of massive perseveration. In one patient expression of needs relied solely on the use of the symbols. In another, expressive speech could be restored to such an extent that communication by the use of symbols was discontinued.

8/10. Internal carotid artery embolism by shotgun pellet.

    Various examples of foreign body embolization of cerebral arteries, usually followed by serious consequences, have been reported (Lindberg et al., 1961; Chason et al., 1963; Steele et al., 1972; Wetli et al., 1972). However, a shotgun pellet entering the left atrium of the heart through a gunshot wound of the chest with subsequent embolic occlusion of one of the carotid arteries appears to be unique. It is the subject of this short communication.

9/10. Comparison of the performances of a fluent and a nonfluent aphasic on a pantomimic referential task.

    The pantomimic performances of a typical Broca's (nonfluent) and Wernicke's (fluent) aphasic were compared with each other and with four normal control subjects on a simple task of nonverbal referential communication. Both aphasic subjects demonstrated only about 50% accuracy in their pantomimic communication. Also, measures were obtained of the motoric fluency of the pantomimes of all subjects and comparisons were made between the fluent and nonfluent aphasics. These measures demonstrated distinct differences in the fluency patterns of the pantomimes of the two aphasic subjects similar to the differences in speech fluency which distinguish and characterize these two types of aphasia; that is, the fluent aphasic pantomimed fluently and like the control subjects and the nonfluent aphasic pantomimed nonfluently. The quantitative and qualitative similarities in the fluency patterns of the speech and the pantomimic behaviors of the aphasic subjects are discussed in terms of their implications for a definition of aphasia.

10/10. Multiple systemic emboli complicating the course of a patient with an atrial septal defect, an atrial septal aneurysm and an endocardial right atrial pacemaker lead.

    We describe an adult patient with a large atrial septal defect, an atrial septal aneurysm and thrombus formation on a transvenous right atrial pacing lead. Because of right-to-left shunting through the atrial septal defect, she developed multiple systemic emboli to the spleen and left kidney (with infarcts), to the left leg, and probably to the brain as a cerebrovascular accident. The fundamental guiding principle of avoiding endocardial pacing leads in patients with congenital intracardiac communications, was violated in this patient, leading to serious dire consequences and complications.
