ABSTRACT
Abstract Introduction Deficits in executive functioning, especially in inhibitory control, are present in children born very premature and/or with very low birth weight (VP/VLBW) and in children with attention-deficit/hyperactivity disorder (ADHD). Objective To evaluate whether ADHD imposes additional inhibitory control (IC) deficits in preschoolers born VP/VLBW. Methods 79 VP/VLBW (4 to 7 years) children were assessed for ADHD using the Schedule for Affective Disorders and Schizophrenia for School Aged Children - Present and Lifetime Version (K-SADS-PL). IC was measured with Conners' Kiddie Continuous Performance Test (K-CPT 2) and the Behavior Rating Inventory of Executive Function - Preschool Version (BRIEF-P).Results: No significant differences were found between ADHD (n = 24) and non-ADHD children (n = 55) for any of the measures (p = 0.062 to p = 0.903). Both groups had deficits in most K-CPT 2 scores compared to normative samples, indicating poor IC and inconsistent reaction times. Conclusions ADHD does not aggravate IC deficits in VP/VLBW children. Either neuropsychological tasks and parent reports of executive functions (EFs) may not be sensitive enough to differentiate VP/VLBW preschoolers with and without ADHD, or these children's EFs are already so impaired that there is not much room for additional impairments imposed by ADHD.

Obsessive-compulsive disorder (OCD) is a chronic and impairing condition. A very small percentage of patients become asymptomatic after treatment. The purpose of this paper was to review the alternative therapies available for OCD when conventional treatment fails. Data were extracted from controlled clinical studies (evidence-based medicine) published on the MEDLINE and Science Citation Index/Web of Science databases between 1975 and 2012. Findings are discussed and suggest that clinicians dealing with refractory OCD patients should: 1) review intrinsic phenomenological aspects of OCD, which could lead to different interpretations and treatment choices; 2) review extrinsic phenomenological aspects of OCD, especially family accommodation, which may be a risk factor for non-response; 3) consider non-conventional pharmacological approaches; 4) consider non-conventional psychotherapeutic approaches; and 5) consider neurobiological approaches
O transtorno obsessivo-compulsivo (TOC) é uma doença crônica e incapacitante. Uma pequena porcentagem de pacientes se torna assintomática após o tratamento. O objetivo deste trabalho foi revisar as alternativas terapêuticas para o tratamento de TOC quando os tratamentos convencionais falham. Os dados foram extraídos de estudos clínicos controlados (medicina baseada em evidências) publicados nas bases de dados MEDLINE e Science Citation Index/Web of Science entre 1975 e de 2012. Os resultados são discutidos e sugerem as seguintes abordagens para profissionais que lidam com TOC refratário: 1) rever aspectos fenomenológicos intrínsecos ao TOC, o que pode levar a entendimentos diferenciados e à escolhas terapêuticas distintas; 2) rever aspectos fenomenológicos extrínsecos ao TOC, principalmente acomodação familiar, que pode ser fator de risco para a não resposta; 3) considerar abordagens farmacológicas não convencionais; 4) considerar abordagens psicoterapêuticas não convencionais; e 5) considerar abordagens neurobiológicas
