MR evaluation of factors predicting the development of rotator cuff tears.

PURPOSE: The purpose of this work was to assess the incidence of various factors predicting impingement in the shoulder. METHOD: MR examination was used to assess various anatomic parameters in 46 patients with clinical abnormalities of the shoulder and 40 asymptomatic volunteers. All patients had undergone surgery, showing no rotator cuff tear. RESULTS: A few of the parameters evaluated were significantly different in the two groups: The acromion was more frequently curved or hook-shaped in patients than in volunteers. The acromiohumeral distances differed (4.87 mm in patients and 6.05 mm in volunteers); so did the coracohumeral distances (7.9 mm in patients and 8.9 mm in volunteers). The shape of the acromioclavicular joint and the anterior covering of the humerus, defined on the coronal view, also differed (1.07 mm in patients and 1.49 mm in volunteers). Only the shapes of the acromioclavicular joint and of the acromion were linked with age. CONCLUSION: All these factors reflected a decrease in the acromiohumeral space, except for the anterior covering of the acromial arch, which could be due to anterior instability.

[The P300 component of evoked potentials in the evaluation of schizophrenia: new evidence and future visions].

OBJECTIVE: To analyze the character as pathophysiological marker of the P300 component in the evaluation of schizophrenic illness. We therefore review clinical and neuropsychological evidence of studies in which this was used as a tool for evaluation to reach a diagnosis. DEVELOPMENT: The P300 component is useful for studying not only cognitive processes but also the physiopathology of complex disorders such as schizophrenia. This component reflects the state of functions of attention control and memory, both necessary for final evaluation of a stimulus. These cognitive functions become altered in schizophrenic illness, as is shown by abnormality in the generation of the P300 component. We review the most relevant results, which permit characterization of the many features of schizophrenia from genetic, symptom, morphology and neuropsychological studies in which the P300 component is particularly relevant. Similarly, we analyze current controversies due to the great heterogeneity of methodology and the nature of the illness itself. CONCLUSIONS: Current understanding allows us to establish that the P300 is a biological marker of relevant aspects of schizophrenia such as the genetic risk of suffering a psychotic episode, determine the type and gravity of the symptoms of the disease, as well as the degree of structural deterioration of the patient. The P300 component is sensitive to the effect of different neuroleptic drugs, on both the symptoms and neuropsychological functions of the patient. These findings let us suggest the P300 component as a valid marker for the evaluation of schizophrenia and the neuropsychological processes.

A case of fetal alcohol syndrome is reported in a intrauterine growth retarded female newborn with dysmorphic features and congenital cardiopathy whose mother suffered from a chronic ethylism during pregnancy. Authors compare this case findings with the reported revisions of other authors.
