Abstract Most adults with attention-deficit/hyperactivity disorder (ADHD) are not recognized and remain untreated, although a large fraction of these individuals are diagnosed and treated for other ...comorbid mental disorders, such as major depressive disorder (MDD). The fact that MDD is one of the most commonly occurring mental disorders with high comorbidity with adult ADHD raises the question whether such comorbidity is associated with differences in the clinical picture of ADHD. Three hundred and twenty adult ADHD outpatients were evaluated. Diagnoses followed DSM-IV criteria. Interviews to evaluate ADHD and oppositional defiant disorder (ODD) were performed based on the Portuguese version of K-SADS-E. Psychiatric comorbidities were investigated using SCID-IV and MINI. Regression models were applied to test MDD association with clinical and demographic outcomes. Subjects presenting ADHD and MDD had a higher frequency of generalized anxiety disorder and social phobia and a lower frequency of substance dependence, grade repetition and school suspensions, when compared to subjects with ADHD without MDD. Furthermore, adults presenting ADHD and MDD reported higher demand for psychotherapy and pharmacological treatment prior to enrollment in the study when compared to ADHD subjects free of MDD. However, contrary to what could be expected based on these data, the presence of MDD was not associated with an earlier ADHD diagnosis. These results point to the need for research and medical education into an earlier and more efficient ADHD diagnosis in patients who search for mental health care.
Abstract Objective The requirement in classificatory systems that some impairment from attention-deficit/hyperactivity disorder (ADHD) symptoms starts before 7 years of age (age of onset of ...impairment criteria – AOC) has been harshly criticized. Although there is evidence that late-onset ADHD is a valid diagnosis, little is known about the role of age of onset of impairment on the clinical profile of adult patients. Methods The diagnoses of 349 adults with ADHD followed DSM-IV criteria. ADHD and oppositional defiant disorder (ODD) were evaluated with the K-SADS-E, and other comorbidities with the SCID-IV and the MINI. Subjects were divided in early and late-onset groups (age of onset of impairment between 7 and 12 years old). The effect of age of onset over clinical and demographic characteristics was tested by regression models. Results Late-onset subjects were diagnosed later ( P = 0.04), had a lower frequency of problems with authority and discipline ( P = 0.004), and lower scores in SNAP-IV ( P < 0.001) and in Barkley’s scale for problems in areas of life activities ( P = 0.03). On the other hand, late-onset patients presented a higher prevalence of comorbid general anxiety disorder (GAD) ( P = 0.01). Both groups had a similar profile in the remaining comorbidities and sociodemographic characteristics. Conclusions This study provides initial evidence that adults with late-onset ADHD have less severity, lower frequency of externalizing symptoms and increased comorbidity with GAD, but similar profile in other comorbidities. In addition, the data suggest that late-onset patients have a higher probability of delayed diagnosis despite the significant impairment of their condition.
Previous studies have suggested that individuals with ADHD have high scores in novelty seeking and harm avoidance. However, it is not known whether personality is associated with specific subtypes ...and dimensions of the disorder. The aim of this study is to test for associations between scores in the temperament and character inventory of C.R. Cloninger with adult ADHD subtypes and severity.
The diagnostic interviews of 296 adult ADHD patients followed the DSM-IV criteria. ADHD dimensions were evaluated with the SNAP-IV scores, and personality dimensions were assessed using the Temperament and Character Inventory.
The combined subtype (n=168) was associated with higher scores in novelty seeking (p<0.001) and lower scores in cooperativeness (p=0.006) than the inattentive subtype (n=128). Higher inattention scores were associated with decreased self-directedness (p<0.001) and increased harm avoidance (p=0.02), whereas higher hyperactivity/impulsivity scores correlated positively with novelty seeking (p<0.001) and persistence (p=0.03).
These findings suggest that personality dimensions are strongly correlated with ADHD subtypes and severity dimensions, pointing to the need for studies evaluating the mechanisms behind this association.
Adults with attention-deficit/hyperactivity disorder (ADHD) are predisposed to smoking, but the neuropsychological correlates of this association have not been elucidated so far. The present study ...evaluates possible associations between cognitive performance and smoking and other comorbidities in adults with ADHD. Two hundred and sixty-four (264) patients were evaluated in the adult ADHD outpatient clinic of the Hospital de Clínicas de Porto Alegre. The diagnoses were based on the DSM-IV criteria and interviews were performed with the Portuguese version of K-SADS-E for ADHD and oppositional-defiant disorder. Axis I psychiatric comorbidities were evaluated with the SCID-IV and the cognitive performance with the Vocabulary and Block Design subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R). The evaluation of the influence of the WAIS-R scores on each dependent variable was performed with logistic regression analyses. Lower scores in the Block Design subtest of WAIS-R were associated with smoking and the presence of anxiety disorder. These results suggest that a subgroup of ADHD patients with lower Block Design subtest scores may be at increased risk of smoking as a cognitive enhancement. Our findings also confirmed the previously suggested association between anxiety and lower Block Design scores.
The aim of the present study is to verify if gender modifies the clinical, adaptative and psychological outcomes of adult attention-deficit/hyperactivity disorder (ADHD) subtypes. We evaluated 219 ...clinically referred adult patients. The interviews followed the DSM-IV criteria,using the K-SADS-E for ADHD and oppositional defiant disorder and SCID-IV for comorbidities. Regression models were used to analyze gender and subtype main effects and interactions in psychiatric outcomes. In the initial sample, 117 patients (53.5%) were of the combined subtype, 88 (40%) were inattentives and 14 (6.5%) hyperactives. There were no significant interactions between gender and subtype in any variable assessed. Men and women did not differ in the relative frequency of each subtype. Patients of the combined subtype in both genders presented a higher severity and increased rates of conduct and ODD disorders than inattentives. The main effects of gender and subtype in this sample are similar to those previously reported in other countries, suggesting the cross-cultural equivalence of the phenotype. The absence of significant interactions between gender and subtype suggests that, at least in clinical-based samples, DSM-IV adult ADHD subtypes present cross-gender validity.
The aim of the present study was to perform a systematic review of the literature on the effects of low-level laser therapy in the treatment of TMD, and to analyze the use of different assessment ...tools. Subjects and Methods Searches were carried out of the BIREME, MEDLINE, PubMed and SciELO electronic databases by two independent researchers for papers published in English and Portuguese using the terms: “temporomandibular joint laser therapy” and “TMJ laser treatment”. Results Following the application of the eligibility criteria, 11 papers were selected for in-depth analysis. The papers analyzed exhibited considerable methodological differences, especially with regard to the number of sessions, anatomic site and duration of low-level laser therapy irradiation, as well as irradiation parameters, diagnostic criteria and assessment tools. Conclusion Further studies are needed, especially randomized clinical trials, to establish the exact dose and ideal parameters for low-level laser therapy and define the best assessment tools in this promising field of research that may benefit individuals with signs and symptoms of TMD.
despite the increasingly careful attempts to reduce perioperative risks, pulmonary complications following surgery are still very common, leading to longer length of hospital stays or death.
to ...describe the incidence of pulmonary complications and identify their association with duration of extracorporeal circulation (ECC), surgery and ischemia, number of bypass grafts performed, location of drains and length of drainage following myocardial revascularization (MRV).
this contemporaneous cohort consisted of 202 patients undergoing elective myocardial revascularization (MRV) with saphenous vein graft and internal mammary artery graft and ECC, at a referral university cardiology hospital in Southern Brazil, from April 2006 to November 2007. The following outcomes were analyzed: duration of mechanical ventilation; pneumonia onset; atelectasis; pleural effusion; location of drains and time of removal; and length of hospital stay.
of the 202 patients, 90 developed some sort of pulmonary complication. The incidence of pleural effusion was 84%, whereas atelectasis was 65%. The following variables were associated with pulmonary complications: duration of ECC (p = 0.003), surgery (p = 0.040) and ischemia (p = 0.001); length of drainage (p = 0.050) and location of pleural drains (p = 0.033); age (p = 0.001); ejection fraction (p = 0.010); diagnosis of asthma (p = 0.047) and preoperative abnormal chest X-ray findings (p = 0.029).
variables related to the complexity of the surgery and preexisting comorbidities are associated with a high incidence of postoperative pulmonary complications. These data reinforce the importance of having patients undergo perioperative clinical assessment to detect early respiratory complications after MRV.
