RESUMO
BACKGROUND: Hereditary transthyretin amyloidosis, caused by transthyretin gene mutations, progresses with systemic impact and often presents peripheral neuropathy. Recent research reveals central nervous system involvement, marked by leptomeningeal amyloid accumulation and transient focal neurological episodes displaying cortical dysfunction. CASE PRESENTATION: A 47-year-old Caucasian man with hereditary transthyretin amyloidosis presented with motor aphasia, right hemiparesis, fever, and an altered state of consciousness. Tests ruled out stroke or infection. While improving, the patient reported an ongoing auditory repetition phenomenon for 48 hours despite efforts to shift focus or introduce new stimuli. CONCLUSION: This represents the first known case report documenting palinacousis in hereditary transthyretin amyloidosis attributed to central nervous system involvement. This case highlights the complexities in assessment and management of patients when neurological and psychiatric symptoms overlap.

BACKGROUND: Cariprazine has emerged as a promising augmenting treatment agent for unipolar depression and as a monotherapy option for bipolar depression. We evaluated cariprazine's efficacy in treating acute major depressive episodes in individuals with major depressive disorder (MDD) or bipolar disorder. METHODS: A systematic review was conducted on MEDLINE, Embase, PsycINFO, Scopus and Web of Science, ClinicalTrials.gov and ScanMedicine. Study quality was assessed using the RoB 2 tool. Pairwise and dose-response meta-analyses were conducted with RStudio. Evidence quality was assessed with GRADE. RESULTS: Nine RCTs meeting inclusion criteria encompassed 4889 participants. Cariprazine, compared to placebo, significantly reduced the MADRS score (MD = -1.49, 95 % CI: -2.22 to -0.76) and demonstrated significantly higher response (RR = 1.21, 95 % CI: 1.12 to 1.30) and remission (RR = 1.19, 95 % CI: 1.06 to 1.34) rates. Subgroup analysis unveiled statistically significant reductions in MADRS score in MDD (MD = -1.15, 95 % CI: -2.04 to -0.26) and bipolar I disorder (BDI) (MD = -2.53, 95 % CI: -3.61 to -1.45), higher response rates for both MDD (RR = 1.19, 95 % CI: 1.08 to 1.31) and BDI (RR = 1.27, 95 % CI: 1.10 to 1.46), and higher remission rates only for BDI (RR = 1.41, 95 % CI: 1.24 to 1.60). A higher rate of treatment discontinuation due to adverse events was observed. LIMITATIONS: Reliance solely on RCTs limits generalisability; strict criteria might not reflect real-world diversity. CONCLUSIONS: Cariprazine demonstrates efficacy in treating major depressive episodes, although variations exist between MDD and BDI and tolerability may be an issue.

BACKGROUND: Compulsory treatment involves the hospital admission of individuals with mental disorders in appropriate facilities through judicial decisions. However, limited information is available regarding the similarities and differences in compulsory treatment legislation in Portuguese-speaking countries. AIMS: To analyse the commonalities and differences in compulsory treatment legislation in Portuguese-speaking countries, where Portuguese is the primary official language, including Angola, Brazil, Cape Verde, East Timor, Guinea-Bissau, Mozambique, Portugal, and São Tomé and Príncipe. METHODS: A comparative analysis of the specific legislation on compulsory treatment in Portuguese-speaking countries was conducted. National development plans were analysed in countries lacking legislation. A purposive sampling of mental health professionals was contacted to gather information on the countries under study. RESULTS: Among the eight Portuguese-speaking countries examined, specific legislation regarding compulsory treatment was found only in Brazil, Cape Verde, and Portugal. These countries, with the lowest poverty rates, exhibited a notable degree of homogeneity in the criteria supporting compulsory treatment, ensuring the protection of individual rights. In contrast, in Angola, East Timor, Guinea-Bissau, Mozambique, and São Tomé and Príncipe, compulsory treatment primarily relies on mental health development plans, resulting in significant variations in the presented criteria. CONCLUSIONS: The significant disparities in compulsory treatment policies among Portuguese-speaking countries, with only Brazil, Cape Verde, and Portugal having specific legislation, underscore the need for a collective effort to establish more consistent procedures and safeguard individual rights.

ABSTRACT: Electroconvulsive therapy (ECT) is a treatment of undisputed efficacy for severe and treatment-resistant psychiatric disorders. Notwithstanding extensive data on efficacy and safety, it is significantly underused, corresponding to one of the most stigmatized approaches in psychiatry. The list of problems for which ECT is potentially effective does not include obsessive-compulsive disorder (OCD), resulting in only a few available case reports in the literature in which OCD is the target of this specific therapeutic strategy. The authors describe a patient with refractory OCD for whom ECT was prescribed, with remarkable clinical response and functional improvement. The existence of a clear response to ECT in reported cases of OCD, albeit in a globally small number of patients, should make it essential to identify predictors of ECT response that could assist clinicians in assessing and guiding such cases, particularly those labeled as refractory to treatment.
