OBJECTIVES To assess the incidence, comorbidity, and patterns of resolution of DSM-IV mood, anxiety, and substance use disorders in individuals with traumatic brain injury (TBI). DESIGN The Structured Clinical Interview for DSM-IV Diagnoses (SCID) was utilized. Diagnoses were determined for three onset points relative to TBI onset: pre-TBI, post-TBI, and(More)
PRIMARY OBJECTIVES To determine the frequency and nature of post-TBI personality disorders (PDs) in a community-based sample of individuals with TBI. RESEARCH DESIGN One hundred individuals with TBI were administered a structural clinical interview to determine Axis II psychopathology. METHODS OF PROCEDURES: The Structured Clinical Interview for DSM-IV(More)
Sporadic and familial malignant melanoma susceptibility has been linked to defects in the chromosomal region 9p21. Recently, a putative 9p21 tumor suppressor gene, the cyclin dependent kinase inhibitor 2 (CDKN2) or p16 gene, has been shown to be deleted, mutated, or rearranged in a high percentage of sporadic melanoma cell lines, as well as mutated in the(More)
BACKGROUND Cholesteatoma is a destructive lesion of the middle ear or mastoid process or both. The molecular and cellular defects that result in the clinical hallmarks of acquired and congenital cholesteatomas, namely invasion, migration, uncoordinated proliferation, altered differentiation, aggressiveness, and recidivism, are unknown. Determining the(More)
Alterations in the tumor-suppressor gene p53 are common in many types of human malignancies, but the potential role of p53 in the pathogenesis of cutaneous melanoma is controversial. The gene product, p53 protein, is normally present in very small amounts in noncancerous tissues. Missense mutations lead to accumulation of mutant p53 in the cells, which(More)
OBJECTIVE This study examined the relationship between Beck Depression Inventory (BDI) scores and current diagnosis of depression, based on The Structured Clinical Interview for DSM-IV Diagnosis (SCID). DESIGN Correlation. SETTING Community-based sample. PARTICIPANTS 100 individuals with traumatic brain injury (TBI) participated in this study, 25 of(More)
The CD44 antigen (ECMRIII, Hermes antigen) is a highly glycosylated cell-surface polypeptide involved in diverse cellular functions, including cell adhesion and lymphocyte-homing receptor activity. CD44 is also expressed in vivo by several tumors, including astrocytomas, meningiomas, and colonic adenocarcinomas. In addition, it has been shown that(More)
The molecular events responsible for tumor progression in human cutaneous malignant melanoma remain unclear; however, critical to the process is the dysregulated proliferation of tumor cells and the development of new vascular channels which allow further growth and dissemination. Connective tissue mast cells (MC) have been implicated in tumor progression(More)
HYPOTHESIS Because many of the biologic phenomena in which mast cells are involved also are observed in human cholesteatoma pathology, the authors hypothesized that mast cells may play a role in this disease. The first test of this hypothesis is to determine whether there are an increased number of mast cells associated with cholesteatomas. BACKGROUND The(More)
