Ultrastructural evaluation of explanted opacified Hydroview (H60M) intraocular lenses.

AIM: To describe the ultrastructural appearance of explanted opacified Hydroview H60M intraocular lenses. METHODS: 14 explanted lenses were examined by scanning electron microscopy, and their appearance compared with a non-implanted H60M lens from the same time period. Wavelength-dispersive x ray spectroscopy (WDX) was performed on two opacified lenses. RESULTS: Subsurface deposits were seen in all explanted opacified lenses. These deposits broke only onto the surface of more densely opacified lenses. WDX confirmed that the deposits contained both calcium and phosphorous, consistent with their being calcium apatite. CONCLUSION: These findings challenge the widely accepted opinion that H60M intraocular lens opacification begins on the surface of the optic.

Psychiatric disposition of patients brought in by crisis intervention team police officers.

BACKGROUND: As part of an effort to improve police interactions with mentally ill citizens, and improve mental health care delivery to subjects in acute distress, the University of Louisville, in conjunction with the Louisville Metro Police, established the crisis intervention team (CIT). CIT is composed of uniformed officers who receive extensive training in crisis intervention and psychiatric issues and who are preferentially called to investigate police calls that may involve a mentally ill individual. METHODS: In an effort to determine the characteristics of the individuals brought to the emergency psychiatric service (EPS) by CIT officers, a comparative (CIT vs. mental inquest warrant [MIW, a citizen-initiated court order to bring someone for psychiatric evaluation because of concerns regarding dangerousness] vs non-CIT/non-MIW), descriptive evaluation was performed. RESULTS: With the exception of a higher rate of schizophrenic subjects brought in by CIT (43.0% vs. 22.1%, non-CIT, P = .002), the demographics, diagnosis, and disposition of CIT-referred subjects were not different in any way from non-CIT patients. Subjects referred on MIWs were more likely to be admitted to a psychiatric hospital than non-MIW patients (71.6% vs. 34.8%, P < .0001), but CIT-referred hospitalization rates were not different from hospitalization rates of self-referred subjects (20.7% vs. 33.3%, ns). CONCLUSIONS: CIT officers appear to do a good job at identifying patients in need of psychiatric care.
