ABSTRACT
Despite the rapid increase of Hispanics in the U.S., there continues to be a lack of adequate psychological assessment tools to examine Spanish-speaking patients with cognitive or neuropsychological disturbances. We investigated the clinical utility of the Multilingual Aphasia Examination-Spanish (MAE-S) in the evaluation of language functions of Hispanic subjects post-traumatic brain injury (TBI). The performance of 40 TBI patients was compared to that of 40 age-, gender-, and education-matched normal controls. Subject groups differed on the Visual Naming (VN), Controlled Oral Word Association (COWA), and Token Test subtests. The VN and COWA subtests were the best discriminators of group membership. Distribution of scores for the patient group on the Rating of Articulation scale additionally indicate subtle articulatory difficulties post-TBI. For all subtests, trauma severity per Glasgow Coma Scale was the best predictor of language performance, over and above the contribution of other clinical and demographic variables. These results are consistent with prior reports of dysphasia post-TBI and suggest that the MAE-S is a sensitive and accurate measure to assess language disturbances in Hispanic populations.

OBJECTIVE: The objective of this study was to compare penetrating and tangential gunshot wounds to the head with regards to demographic, neurobehavioural and clinical outcome measures. METHODS: Twenty-nine patients with penetrating gunshot wounds (P-GSW) and 11 patients with tangential gunshot wound (T-GSW) to the head admitted to an acute neurotrauma service were compared using standardized neurobehavioural and clinical outcome measures. RESULTS: The mean GCS was 10.5 +/- 0.79 for the P-GSW group and 13.4 +/- 0.72 for the T-GSW group. The mean AIS-CNS for the P-GSW group was 5.00 +/- 0 and for the T-GSW group was 3.7 +/- 0.27. Significance was found on Digit Span (p < 0.05) and Block Design (p < 0.009) subtests. Outcomes between the two groups were similar, except for significant differences were found for acute length of stay (LOS) (P-GSW was 47.72 +/- 13.2 and T-GSW group was 13.0 +/- 1.3, p = 0.005) and for acute care charges (P-GSW group was $150,533 +/- 23,834 and T-GSW group was $70,712 +/- 16,587, p = 0.05). CONCLUSIONS: Initially, a penetrating gunshot wound is a more severe and costly injury than a tangential gunshot wound to the head, however T-GSW possess significant deficits and, if the patient survives past the acute phase of recovery, the two groups have similar functional outcomes. Future standard classification, neuropsychological, and clinical outcome measures.

STUDY DESIGN: This was a blind, prospective study of the effect of sera from patients with spinal cord and head injuries on osteoblast proliferation. OBJECTIVES: The authors studied whether a humoral factor that stimulates the formation of heterotopic bone is released into the circulation after a neural injury. BACKGROUND DATA: Other authors have shown that a humoral osteoinductive factor may be released after head and spinal cord injuries. METHODS: Serum was obtained at certain times throughout the first 12 weeks post-injury and from control subjects. It was incubated with osteoblasts harvested from fetal rats, as well as with fibroblast controls. RESULTS: There was a significant rise in serum mitogenic activity after injury in both groups. When patients that developed heterotopic ossification were compared to other patients and controls, no significant differences were seen. CONCLUSIONS: This in vitro study fails to support a humoral mechanism for heterotopic ossification after spinal cord or brain injuries.

A patient with an acute ischemic stroke had an interatrial septal aneurysm shown by transesophageal echocardiography. Interatrial shunting, compatible with a patent foramen ovale, was observed on a follow-up study after a second stroke. This was seen in association with a right atrial thrombus. This case illustrates that an interatrial septal aneurysm serves as a marker for potential interatrial shunting, which can lead to paradoxical cerebral embolism.
