When nonwords activate semantics better than words.

We conducted a strong test of the idea that visual word processing and the activation of a printed word's meaning proceeds at a rate scaled by the temporal evolution of a unique and stable phonological code. Using the lexical decision task, and readers fluent in the two alphabets of Serbo-Croatian, we compared the priming of a target word such as automat by the semantically related word ROBOT and by the nonword ROBOT. Whereas the Serbo-Croatian word ROBOT can support two phonological codes, /robot/ and /rovot/, the nonword ROBOT composed by illegally mixing Roman and Cyrillic letters can support only the phonological code /robot/, that corresponding to the word whose meaning is related to automat's. At a prime duration of 35 ms, the lexical decision on the target automat was facilitated by ROBOT but not by ROBOT. At a prime duration of 125 ms, the word ROBOT was the more effective prime. One consequence of phonology's leading role in visual word recognition is that a nonword can sometimes activate a given word's meaning better than the word itself.

Aortic occlusion in a patient with antiphospholipid antibody syndrome in systemic lupus erythematosus.

A 41-year-old woman with systemic lupus erythematosus and lupus anticoagulant developed aortic thrombosis. The patient was receiving low dose aspirin. Aortography showed a complete obliteration of the infrarenal aorta. Computed tomography and magnetic resonance imaging showed no evidence of aortitis. The patient improved with medical treatment. Six other published cases are reviewed.

[Spondylodiscitis caused by Fusobacterium nucleatum. Apropos of a case]. / Spondylodiscite à Fusobacterium nucleatum. A propos d'un cas.

Spondylodiscitis is rarely caused by anaerobic germs and occurs mainly in patients weakened by another infection. We report a case of Fusobacterium nucleatum spondylodiscitis in a 63-year-old man. This is the third such report and the second in a non-immunodepressed patient. The clinical presentation and laboratory findings in this type of spondylodiscitis vary little from those produced by other germs. Magnetic resonance imaging is the most useful diagnostic tool for spondylodiscitis. The germ is isolated from a discal puncture aspirate in 66% of the cases but can also be obtained from blood cultures. Anaerobic germs are usually sensitive to penicillin or cephalosporins.

Cervical epidural infection. Four case-reports.

The authors report four cases of cervical epidural infection, in two females (aged 58 and 82 years) and two males (aged 41 and 51 years). Risk factors were noninsulindependent diabetes mellitus in one patient and multiple myeloma treated by chemotherapy in another. Duration of cervical pain at evaluation was five to 15 days. Three patients had a fever and a neurologic deficit: one had brachial diplegia; the myeloma patient developed brachial diplegia after a lumbar puncture and the diabetic patient developed quadriplegia with respiratory disorders also after a lumbar puncture. Cerebrospinal fluid studies showed elevated protein levels with approximately 20 cells per mm3 and no pathogens in smears or cultures. Roentgenograms were normal at admission. The diagnosis was established by myelography (n = 2) and/or computed tomography (n = 2) and/or magnetic resonance imaging (n = 2). The infected area was anterior in three cases and posterolateral in one. Two to seven vertebral levels were affected. A Staphylococcus aureus was recovered from the blood cultures in all four cases and from a local specimen in one of the two patients who had a laminectomy. Of the two patients who did not have surgery, one had a normal neurologic evaluation and the other was an elderly patient with myeloma. In both, antimicrobial and corticosteroid therapy ensured complete resolution of the infection, and the myeloma patient recovered normal neurologic function. Residual neurologic loss was seen in one of the two surgically-treated patients. Two patients developed discitis.

Shrinking lung syndrome in systemic lupus erythematosus. A report of three cases.

Shrinking lung syndrome of systemic lupus erythematosus is characterized by dyspnea, diaphragmatic elevation with decreased mobility, and a restrictive defect. We report three cases in females with systemic lupus erythematosus aged 25, 29, and 42 years. Dyspnea and chest pain were present in all three patients. Elevation of the diaphragm was bilateral in two patients and unilateral in one. Two patients had a very severe restrictive defect. Onset of the pulmonary manifestations occurred in the absence of a flare of the connective tissue disease in two patients. Corticosteroid therapy consistently produced a clinical improvement with a decrease in the restrictive defect. Evidence suggesting diaphragmatic dysfunction is discussed.
