This article continues our presentation of the Brazilian Psychiatric Association guidelines for the management of patients with suicidal behavior, with a focus on screening, intervention, postvention, prevention, and promotion. For the development of these guidelines, we conducted a systematic review of the MEDLINE (via PubMed), Cochrane Database of Systematic Reviews, Web of Science, and SciELO databases for research published from 1997 to 2020. Systematic reviews, clinical trials, and cohort/observational studies on screening, intervention, and prevention in suicidal behavior were included. This project involved 14 Brazilian psychiatry professionals and 1 psychologist selected by the Psychiatric Emergencies Committee of the Brazilian Psychiatric Association for their experience and knowledge in psychiatry and psychiatric emergencies. Publications were evaluated according to the 2011 Oxford Center for Evidence-Based Medicine (OCEBM) Levels of Evidence Classification. Eighty-five articles were reviewed (of 5,362 initially collected and 755 abstracts on the drug approach). Forms of screening, intervention, and prevention are presented. The intervention section presents evidence for psychotherapeutic and drug interventions. For the latter, it is important to remember that each medication is effective only for specific groups and should not replace treatment protocols. We maintain our recommendation for the use of universal screening plus intervention. Although the various studies differ in terms of the populations evaluated and several proposals are presented, there is already significant evidence for certain interventions. Suicidal behavior can be analyzed by evidence-based medicine protocols. Currently, the best strategy is to combine several techniques through the Safety Plan. Nevertheless, further research on the topic is needed to elucidate some approaches with particular potential for intervention and prevention. Systematic review registry number: CRD42020206517

Suicide is a global public health problem that causes the loss of more than 800,000 lives each year, principally among young people. In Brazil, the average mortality rate attributable to suicide is approximately 5.23 per 100,000 population. Although many guidelines have been published for the management of suicidal behavior, to date, there are no recent guidelines based on the principles of evidence-based medicine that apply to the reality of suicide in Brazil. The objective of this work is to provide key guidelines for managing patients with suicidal behavior in Brazil. This project involved 11 Brazilian psychiatry professionals selected by the Psychiatric Emergencies Committee (Comissão de Emergências Psiquiátricas) of the Brazilian Psychiatric Association for their experience and knowledge in psychiatry and psychiatric emergencies. For the development of these guidelines, 79 articles were reviewed (from 5,362 initially collected and 755 abstracts). In this review, we present definitions, risk and protective factors, assessments, and an introduction to the Safety Plan. Systematic review registry number: CRD42020206517

Objective: To present the essential guidelines for pharmacological management of patients with psychomotor agitation in Brazil. Methods: This is a systematic review of articles retrieved from the MEDLINE (PubMed), Cochrane Database of Systematic Reviews, and SciELO databases published from 1997 to 2017. Other relevant articles in the literature were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools. Results: Of 5,362 articles retrieved, 1,731 abstracts were selected for further reading. The final sample included 74 articles that met all inclusion criteria. The evidence shows that pharmacologic treatment is indicated only after non-pharmacologic approaches have failed. The cause of the agitation, side effects of the medications, and contraindications must guide the medication choice. The oral route should be preferred for drug administration; IV administration must be avoided. All subjects must be monitored before and after medication administration. Conclusion: If non-pharmacological strategies fail, medications are needed to control agitation and violent behavior. Once medicated, the patient should be monitored until a tranquil state is possible without excessive sedation. Systematic review registry number: CRD42017054440.

Objective: To present the essential guidelines for non-pharmacological management of patients with psychomotor agitation in Brazil. Methods: These guidelines were developed based on a systematic review of articles published from 1997 to 2017, retrieved from MEDLINE (PubMed), Cochrane Database of Systematic Review, and SciELO. Other relevant articles identified by searching the reference lists of included studies were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools. Results: We initially selected 1,731 abstracts among 5,362 articles. The final sample included 104 articles that fulfilled all the inclusion criteria. The management of agitated patients should always start with the least coercive approach. The initial non-pharmacological measures include a verbal strategy and referral of the patient to the appropriate setting, preferably a facility designed for the care of psychiatric patients with controlled noise, lighting, and safety aspects. Verbal de-escalation techniques have been shown to decrease agitation and reduce the potential for associated violence in the emergency setting. The possibility of underlying medical etiologies must be considered first and foremost. Particular attention should be paid to the patient’s appearance and behavior, physical signs, and mental state. If agitation is severe, rapid tranquilization with medications is recommended. Finally, if verbal measures fail to contain the patient, physical restraint should be performed as the ultimate measure for patient protection, and always be accompanied by rapid tranquilization. Healthcare teams must be thoroughly trained to use these techniques and overcome difficulties if the verbal approach fails. It is important that healthcare professionals be trained in non-pharmacological management of patients with psychomotor agitation as part of the requirements for a degree and graduate degree. Conclusion: The non-pharmacological management of agitated patients should follow the hierarchy of less invasive to more invasive and coercive measures, starting with referral of the patient to an appropriate environment, management by a trained team, use of verbal techniques, performance of physical and mental assessment, use of medications, and, if unavoidable, use of the mechanical restraint.

Este artigo revisa o potencial papel do tratamento medicamentoso para os adenomas hipofisários secretores de ACTH, TSH e aqueles clinicamente não-funcionantes (ACNF), Metirapona, mitotano e cetoconazol (preferível por causar menos efeitos colaterais) são as drogas mais eficazes no controle do hipercortisolismo, mas nenhuma delas supera a eficácia da cirurgia transesfenoidal (TSA). O tratamento medicamentoso da doença de Cushing está, portanto, melhor indicado para pacientes aguardando o efeito pleno da radioterapia ou, como alternativa para esta última, em casos de hipercortisolismo persistente após TSA, e para pacientes com rejeição ou limitações clínicas para a cirurgia. Outra indicação potencial seria em idosos com microadenomas ou pequenos macroadenomas, ou em casos associados a sela vazia. No que se refere aos adenomas secretores de TSH, os análogos somatostatínicos (SRIFa) proporcionam normalização dos hormônios tiroideanos em até 95% dos casos. Assim, eles podem se mostrar úteis em casos de insucesso da cirurgia ou como terapia primária de casos selecionados. Ocasionalmente, agonistas dopaminérgicos (DA), sobretudo a cabergolina, também podem ser eficazes. Em contraste, DA e SRIFa raramente induzem uma significante redução das dimensões dos ACNFs. Por isso, em pacientes com tais tumores, essas drogas devem ser principalmente consideradas diante de contra-indicações ou limitações clínicas para a cirurgia ou quando a cirurgia e a radioterapia tenham sido mal-sucedidas.

This article reviews the potencial role of medical treatment for both ACTH and TSH secreting pituitary adenomas, as well as for clinically non-functionning pituitary adenomas (CNFPA). Metyrapone, mitotane and ketoconazole (preferable for causing less side-effects) are the most effective drugs for the control of hypercortisolism but none of them surpasses the efficacy of transsphenoidal surgery (TSA). Drug therapy in Cushing's disease is therefore better indicated for patients waiting for the full effect of radiotherapy or, as an alternative to radiotherapy, for cases of TSA failure as well as patients that refuse or have clinical limitations to surgery. Other potential indications for medical treatment in Cushing's disease include elderly patients with microadenomas or small macroadenomas, as well as cases associated to an empty sella. Concerning TSH-secreting adenomas, somatostatin analogues (SRIFa) lead to normalization of thyroid hormones in up to 95% of treated patients. Therefore they may represent an useful tool for long-term treatment of such rare tumors in case of surgery failure or as primary therapy for selected cases. Occasionaly, dopamine agonists (DA), especially cabergoline, may also be efficacious in normalizing hormone levels. In contrast, DA and SRIFa rarely induce significant tumor shrinkage in patients with CNFPA. Thus, these drugs should be considered particularly for patients who are poor candidates for surgery or in whom surgery and radiotherapy have failed to control the disease.

O recente desenvolvimento de novas drogas, particularmente os análogos da somatotastina (SRIFa), representou um grande progresso na terapia dos tumores hipofisários. Os SRIFa mostram-se bastante eficazes na normalização dos níveis de GH e IGF-1 em acromegálicos e podem ser uma alternativa para a cirurgia transesfenoidal, mas seu uso como terapia primária da acromegalia fica limitado pelo pequeno efeito dessas drogas na redução das dimensões do tumor. Os resultados preliminares com os antagonistas do receptor de GH, como o pegvisomant, são bastante animadores. Tais drogas permitem a normalização do IGF-1 e melhora clínica em mais de 80% dos casos; entretanto, não causam redução tumoral. Agonistas dopaminérgicos (DA) representam a terapia de escolha para microprolactinomas sintomáticos e macroprolactinomas, permitindo normalização dos níveis da prolactina e redução do volume do adenoma na maioria dos pacientes. Podem também ser eventualmente eficazes em acromegálicos, sobretudo naqueles com adenomas co-secretores de prolactina e níveis não muito elevados de GH e IGF-1. Devido a sua maior eficácia e melhor tolerabilidade, a cabergolina representa o DA de escolha para o manuseio dos prolactinomas e da acromegalia.

The recent development of new drugs, particularly the somatostatin analogues (SRIFa), represents a great advance in the therapy of pituitary tumours. SRIFas are very effective in normalizing GH and IGF-1 levels in acromegaly and may be an effective alternative to transsphenoidal surgery. However, their usefulness as primary therapy for acromegaly is limited due to the small effect on tumour size. According to early data from clinical trials, pegvisomant, a GH receptor antagonist, seems to be a promising therapeutic tool in the management of acromegalic patients. This drug induces significant clinical improvement and normalization of IGF-1 levels in nearly all patients. However, it does not induce tumor shrinkage. Dopamine agonists (DA) are the preferred therapy for both symptomatic microprolactinomas and macroprolactinomas; their use result in normalization of prolactin levels and tumor shrinkage in most treated patients. They also may be useful in acromegaly, mainly in patients whose adenoma co-secrete prolactin and those with mild elevation of GH and IGF-1 levels. Due to its greater effectiveness and better tolerability, cabergoline represents the DA of choice for the management of prolactinomas and acromegaly.
