Comprehensive treatments for social cognitive deficits in schizophrenia: A critical review and effect-size analysis of controlled studies

Recent advances in psychosocial treatments for schizophrenia have targeted social cognitive deficits. A critical literature review and effect-size (ES) analysis was conducted to investigate the efficacy of comprehensive programs of social cognitive training in schizophrenia. Results revealed 16 controlled studies consisting of seven models of comprehensive treatment with only three of these treatment models investigated in more than one study. The effects of social cognitive training were reported in 11/15 studies that included facial affect recognition skills (ES=.84) and 10/13 studies that included theory-of-mind (ES=.70) as outcomes. Less than half (4/9) of studies that measured attributional style as an outcome reported effects of treatment, but effect sizes across studies were significant (ESs=.30-.52). The effect sizes for symptoms were modest, but, with the exception of positive symptoms, significant (ESs=.32-.40). The majority of trials were randomized (13/16), selected active control conditions (11/16) and included at least 30 participants (12/16). Concerns for this area of research include the absence of blinded outcome raters in more than 50% of trials and low rates of utilization of procedures for maintaining treatment fidelity. These findings provide preliminary support for the broader use of comprehensive social cognitive training procedures as a psychosocial intervention for schizophrenia.

(Un)suitability of the use of pH buffers in biological, biochemical and environmental studies and their interaction with metal ions – a review

The use of buffers to maintain the pH within a desired range is a very common practice in chemical, biochemical and biological studies. Among them, zwitterionic N-substituted aminosulfonic acids, usually known as Good’s buffers, although widely used, can complex metals and interact with biological systems. The present work reviews, discusses and updates the metal complexation characteristics of thirty one commercially available buffers. In addition, their impact on biological systems is also presented. The influences of these buffers on the results obtained in biological, biochemical and environmental studies, with special focus on their interaction with metal ions, are highlighted and critically reviewed. Using chemical speciation simulations, based on the current knowledge of the metal–buffer stability constants, a proposal of the most adequate buffer to employ for a given metal ion is presented.

Estomatologia Pediátrica – Formação por Case-Studies

A Unidade de Estomatologia do HDE constitui local de referenciação de patologia complexa e com frequência rara. Os autores apresentam vários casos clínicos, com compromisso estomatológico relevante, seja por óbvia alteração do crescimento maxilo-facial, seja por alterações relevantes da mucosa, seja por doença multiquística dos maxilares. Assim, privilegiando-se a vertente clínica da comunicação, através da projecção de fotografias dos doentes e de outra imagiologia, apresentam-se casos de síndrome de Gorlin-Goltz, de disqueratose congénita, de síndrome de Ondine, de doença de Behcet e de síndrome autoinflamatório. Comentam-se, em cada situação, as dificuldades diagnósticas e as opções terapêuticas. Sempre que oportuno, discute-se a repercussão, quer da patologia quer da terapêutica, no crescimento da criança, na sua vertente maxilofacial.
