Diagnostic accuracy of maxillofacial trauma two-dimensional and three-dimensional computed tomographic scans: comparison of oral surgeons, head and neck surgeons, plastic surgeons, and neuroradiologists.

Background: The authors' objectives were to study differences in diagnostic accuracy between two- and three-dimensional computed tomographic scans and among the specialties of plastic surgery, head and neck surgery, oral surgery, and neuroradiology, since this had not previously been done.

Methods: Four groups of subspecialists completed time-proctored tests of 20 maxillofacial trauma scans with zygomatic arch, zygomatic complex, orbital, Le Fort I, II, III, mandibular and panfacial fractures from five institutions (n = 40). Accuracy of diagnosis and indication for surgery, efficiency, and preference were assessed.

Incidence of cleft pathology in Greater New Orleans before and after Hurricane Katrina.

Background: Reports after the 2005 Hurricane Katrina have documented an increase in stress reactions and environmental teratogens (arsenic, mold, alcohol).

Objective: To assess the incidence of cleft pathology before and after the hurricane, and the distribution of cleft cases by gender and race.

Methods: Retrospective chart review of cleft lip with or without cleft palate (CL/P) and cleft palate (CP) cases registered with the Cleft and Craniofacial Team at Children's Hospital of New Orleans, the surgical center that treated cleft cases in Greater New Orleans between 2004 and 2007.

PTSD and dopaminergic genes, DRD2 and DAT, in multigenerational families exposed to the Spitak earthquake.

The objective of this study was to assess the generality of the association of DRD2 and DAT genes and Post-Traumatic Stress Disorder (PTSD) diagnosis/symptom severity. Two hundred ethnic Armenians from 12 multigenerational families exposed to the catastrophic 1988 Spitak earthquake were studied. Common polymorphisms A1/A2 alleles of the DRD2 and '9' repeat allele of DAT gene were genotyped.

Heritabilities of symptoms of posttraumatic stress disorder, anxiety, and depression in earthquake exposed Armenian families.

Objective: To examine the heritabilities of symptoms of posttraumatic stress disorder (PTSD), anxiety, depression, and the shared genetic component of these symptoms among family members exposed to the 1988 Spitak earthquake in Armenia.

Methods: Two hundred members of 12 multigenerational families exposed to the Spitak earthquake were studied using a battery that assessed earthquake exposure and symptoms of PTSD, anxiety, and depression. Heritabilities of these phenotypes were determined using variance component analyses and shared genetic vulnerabilities between these phenotypes were determined using bivariate analyses.

Depression and PTSD symptoms among bereaved adolescents 6(1/2) years after the 1988 Spitak earthquake.

Objective: To compare depression and PTSD symptoms of parentally bereaved adolescents and a comparison group after a catastrophic natural disaster.

Method: Six and a half years after the Spitak earthquake, 48 parentally bereaved adolescents and a comparison group of 44 subjects with no parental loss were evaluated using the Depression Self - Rating Scale (DSRS) and Child Posttraumatic Stress Disorder Reaction Index (CPTSD-RI).

Results: Orphans scored significantly higher on depression than those who lost a father (Mean DSRS scores: 20.
