Hyperthyroidism and depression: a clinical case of atypical thyrotoxicosis manifestation.

The relationship between psychiatric symptoms and thyroid function has been well known and studied since antiquity. The common view is that clinical hypothyroidism is associated with depressive symptoms, whereas the psychiatric manifestations of hyperthyroidism are agitation, emotional lability, hyperexcitability, occasionally accompanied by angry outbursts, and euphoria. The case here reported overturns this conventional medical knowledge. A 73-year-old Italian woman experienced a severe major depressive episode with psychotic and melancholic features during laboratory thyrotoxicosis. No classical clinical signs and symptoms of thyrotoxicosis were present. Psychiatric symptoms improved together with the resolution of the hyperthyroid state. Historically, different cases of so-called 'apathetic hyperthyroidism' have been described. Recent neuroimaging and animal studies provided possible neurobiological explanations, showing how the excess thyroid hormones could affect brain structures involved in the regulation of mood, leading to depression. A direct link between hyperthyroidism and depression seems to be likely. This insight may be relevant in facilitating early diagnosis of thyroid disease and the planning of therapeutic strategies.

Compulsory and voluntary admissions in comparison: A 9-year long observational study.

BACKGROUND: Few studies, so far, have been specifically designed to highlight the features related to Compulsory Admissions (CA) and Voluntary Admissions (VA) in Italian psychiatric emergency wards. AIMS: The main purpose of this observational study was to compare the sociodemographic and clinical characteristics of VA and CA and to explore possible predictors of re-admissions. METHODS: During a 6-month Index Period (February, the 1st-July, the 31st 2008) all psychiatric admissions were documented and then followed-up through all available informatic systems for the next 9 years. RESULTS: Out of 390 hospitalizations, 101 (25.9%) were compulsory (CA rate was 2.79 per 10,000 inhabitants per year, mean duration of hospitalizations of 7.33 ± 7.84 days). Diagnoses were recorded for the 325 patients who had been hospitalized during index period: schizophrenic psychoses ([p = .042], in particular schizophrenia [p = .027]), manic episode (p = .044), and delusional disorders (p = .009) were associated with CA; conversely, the diagnosis of unipolar major depression (p = .005) and personality disorders (p = .048) were significantly more frequent in VA. The 325 admitted patients were followed up for 1,801 person-years. No significant differences were found in terms of drop-outs, transferring, and discharge rates, and mortality rates due to both natural causes and suicides. Factors associated with at least one compulsory readmission were younger age and having had a previous CA (p = .011); conversely having been engaged with psychiatric services for over 1 year prior to index hospitalization was protective for a subsequent CA (p = .013). CONCLUSIONS: After a 40-year old political reform, the current study shows that, in a context of integrated outpatient and inpatient services, engagement with outpatient care may be protective for compulsory rehospitalization.

Rates of comorbid obsessive-compulsive disorder in eating disorders: A meta-analysis of the literature.

BACKGROUND: The high comorbidity between Eating Disorders (EDs) and Obsessive-Compulsive disorder (OCD) is well known, as well as its implications in terms of worse outcome and need to adapt treatment. Estimates of OCD comorbidities in EDs are variable in different studies and poorly informative for clinical purposes. In this study, we sought to derive more consistent estimates, taking into account potential methodological and sampling confounding factors. METHODS: We searched published studies reporting lifetime and current rates of comorbid OCD in ED samples based on recent diagnostic criteria. Comorbidity rates were meta-analyzed using a binary random effects model. Heterogeneity among the studies and publication bias were systematically checked. Potential confounding factors were tested by meta-regression analysis and adjusted by sensitivity analysis. RESULTS: Globally, respectively 18% and 15% of all patients with an ED had a lifetime and current comorbidity with OCD. Rates were slightly higher in anorexia (19% and 14%) than in bulimia nervosa (13% and 9%), although only the current comorbid OCD was significantly higher in anorexia than in bulimia. Prospective follow-up studies provided considerably higher lifetime estimates (EDs 38%, anorexia 44%, bulimia 19%). LIMITATIONS: Temporal/causal relationship between ED and OCD could not be defined. CONCLUSIONS: OCD comorbidity in EDs is a relevant phenomenon, affecting almost one fifth of the patients in cross-sectional observations and up to nearly 40% in prospective follow-up studies. These data indicate the need for focused attention to non-food or body-shape related OCD symptoms, for better diagnostic and prognostic accuracy, and targeted treatment.
