Ethnicity and psychopathology: A meta-analytic review of 31 years of comparative MMPI/MMPI-2 research.

Meta-analyses were performed on 25 comparative Minnesota Multiphasic Personality Inventory (MMPI) and MMPI-2 studies of 1,428 male African Americans versus 2,837 male European Americans, 12 studies of 1,053 female African Americans versus 1,470 female European Americans, and 13 studies of 500 male Latino Americans and 1,345 male European Americans. Aggregate effect sizes suggest higher scores for ethnic minority groups than for European Americans on some MMPI/MMPI-2 scales and lower scores on others. However, none of the aggregate effect sizes suggest substantive differences from either a statistical or clinical perspective. The MMPI and MMPI-2 apparently do not unfairly portray African Americans and Latinos as pathological. Effect sizes across studies generally did not vary as a function of sociodemographic variables, research setting, or use of the MMPI versus MMPI-2. It is recommended that additional between- and within-ethnic groups psychopathology research continue. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Anterior segment OCT-based diagnosis and management of retained Descemet''s membrane following penetrating keratoplasty

PURPOSE: To report a case of retained Descemet's membrane after penetrating keratoplasty for congenital hereditary endothelial dystrophy (CHED) documented by anterior segment optical coherence tomography and review of literature. METHODS: Case report and review of literature. RESULTS: A 14-year-old boy underwent penetrating keratoplasty for CHED. A retained host Descemet's membrane was detected with a supernumerary anterior chamber on the first postoperative day. The retained Descemet's membrane was documented using slit lamp adapted anterior segment optical coherence tomography (SLOCT). Surgical intervention for the Descemet's membrane removal was done in the third postoperative week. The complete removal of the membrane was confirmed on SLOCT. CONCLUSION: Inadvertent retention of the host Descemet's membrane is a rare but possible complication in penetrating keratoplasty for CHED. Proper anticipation, early detection and removal will help in preventing any undue risk of graft failure.     

Paradoxes of masochism.

Presents 5 paradoxes of masochism, which delineate intrapsychic and interpersonal patterns in which pain and "unpleasure" seem to become aims. Elements of the apparent contradictions inherent in masochistic disorders and some of their transference and countertransference implications are discussed. The 5 paradoxes highlight (1) intrapsychic conflict around issues of drive and defense, (2) conflict between autonomy and gratification through depending on others, (3) pain inherent in the quest for perfection, (4) pain associated with attachment to the object, and (5) pleasure evokes physical pain and injury, a screen for early dire physical trauma. Case material illustrates each paradox. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Aquatic passive sampling of herbicides on naked particle loaded membranes: accelerated measurement and empirical estimation of kinetic parameters

Water-sampler equilibrium partitioning coefficients and aqueous boundary layer mass transfer coefficients for atrazine, diuron, hexazionone and fluometuron onto C18 and SDB-RPS Empore disk-based aquatic passive samplers have been determined experimentally under a laminar flow regime (Re = 5400). The method involved accelerating the time to equilibrium of the samplers by exposing them to three water concentrations, decreasing stepwise to 50% and then 25% of the original concentration. Assuming first-order Fickian kinetics across a rate-limiting aqueous boundary layer, both parameters are determined computationally by unconstrained nonlinear optimization. In addition, a method of estimation of mass transfer coefficients--therefore sampling rates--using the dimension-less Sherwood correlation developed for laminar flow over a flat plate is applied. For each of the herbicides, this correlation is validated to within 40% of the experimental data.The study demonstrates that for trace concentrations (sub 0.1 microg/L) and these flow conditions, a naked Empore disk performs well as an integrative sampler over short deployments (up to 7 days) for the range of polar herbicides investigated. The SDB-RPS disk allows a longer integrative period than the C18 disk due to its higher sorbent mass and/or its more polar sorbent chemistry. This work also suggests that for certain passive sampler designs, empirical estimation of sampling rates may be possible using correlations that have been available in the chemical engineering literature for some time.
