Objectives
Bipolar disorder (BD) is intricately associated with chronic clinical conditions. Medical comorbidity is not only more prevalent in mood disorders, but is associated with increased costs, cognitive impairment and, ultimately, premature mortality. Oxidative stress and inflammation may mediate part of this association. To further investigate the association between medical comorbidity status and clinical improvement with adjuvant N acetyl cysteine (NAC) in the context of a placebo-controlled trial.Methods
Placebo-controlled randomized clinical trial assessing the effect of NAC over 24 weeks. Symptomatic and functional outcomes were collected over the study period. Medical comorbidities were self-reported, and we took special interest in cardiovascular and endocrine conditions. We evaluated change from baseline to endpoint and the interaction between change and reported medical comorbidities.Results
Fifty-one percent of patients reported have a cardiovascular or endocrine comorbidity. Although not found for depressive symptoms or quality of life, a significant interaction between medical comorbidity and change scores was consistently found for all functional outcomes. This indicated an advantage of NAC over placebo in those with a clinical comorbidity.Conclusion
Systemic illness moderated only the effect of NAC on functioning, not on depression. Demonstrating an improvement in functional outcomes with an agent that modulates redox and inflammatory pathways, this study lends empirical support to the idea that medical and psychiatric comorbidity are additive in contributing to allostatic states. One intriguing possibility is that comorbid clinical illness could be a marker for more severe oxidative stress states – and thus guide antioxidant use – in BD. 相似文献394.

Objective:
The aim of this study is to present a comprehensive profile of clinical and psychosocial characteristics of children with psychogenic nonepileptic seizures and to assess the short-term outcome of these patients.Materials and Methods:
The subjects were consecutive cases of children with a diagnosis of nonepileptic seizures (N=17, mean age = 10.7 years, S.D. = 1.26) and two groups of control groups matched on age and sex: true seizure group and healthy controls. All the children were recruited from the out-patient services of the Department of Pediatrics of a tertiary care teaching hospital in North India. Detailed history taking and clinical examination was done in the case of every child. A standard 18 channel EEG was done in all the children and a video EEG was done in 12 cases of children with nonepileptic seizures. The Childhood Psychopathology Measurement Schedule (CPMS) and Life Events Scale for Indian Children (LESIC) were used to measure the children''s emotional and behavioral functioning at home, and the number of life events and the stress associated with these events in the preceding year and the year before that. Short-term outcome was examined three to six months after the diagnosis of nonepileptic seizures was made.Results:
Unresponsiveness without marked motor manifestations was the most common “ictal” characteristic of the nonepileptic seizures. Pelvic thrusting, upper and lower limb movements, head movements, and vocalization were observed in less than one-third of the patients. Increased psychosocial stress and significantly higher number of life events in the preceding year were found to characterize children with nonepileptic seizures, as compared to the two control groups. The nonepileptic seizures and true seizures groups had a higher proportion of children with psychopathology scores in the clinically significant maladjustment range, as compared to those in the healthy control group. A majority of the patients (82.4%) either recovered completely or had more than 50% reduction in the frequency of their symptoms, after three to six months of initiation of therapy.Conclusions:
Psychosocial stress is common among children with nonepileptic seizures. Confirmatory diagnosis by video EEG, along with prompt psychosocial intervention, often results in a favorable outcome for most children with nonepileptic seizures. 相似文献396.

Depression is one of the most frequent comorbidities occurring in Parkinson's disease, affecting up to 50% of patients. Depression is associated with severe negative symptoms and has been shown to contribute to an increased rate of decline of both cognitive and motor function, profoundly impacting on the patient's quality of life. The symptoms of depression overlap with the motor features of Parkinson's disease, making detection difficult. Moreover, the lack of specialized screening tools means that depression remains undiagnosed and untreated in a high percentage of patients. However, depression in Parkinson's disease, when identified early, can be effectively treated with a variety of antidepressant medications, improving quality of life and preserving daily function. The focus of this review is to provide an overview of current knowledge regarding depression in Parkinson's disease, followed by a practical discussion addressing the issues of the detection, diagnosis and treatment. 相似文献
