Excessive chronic alcohol users, and particularly patients with alcohol use disorder, may present an alcohol withdrawal syndrome if they abruptly stop drinking. Alcohol withdrawal syndrome requires pharmacological treatment for the treatment of withdrawal symptoms and to prevent withdrawal complications. Medically assisted withdrawal treatment is used in alcohol treatment units, but it is also frequently required in patients admitted to hospital for other conditions.Review of major guidelines covering treatment of withdrawal syndrome with the aim to describe recent evidence and recommendations about the pharmacological treatment for alcohol withdrawal syndrome.Four major guidelines concerning treatment of withdrawal syndrome were selected (National Institute for Health and Care Excellence, American Society of Addiction Medicine, World Federation of Societies of Biological Psychiatry and American Psychiatric Association) and screened for the recommendations and level of evidence on drug prescribing for alcohol withdrawal syndrome. The Maudsley guidelines were also considered in this review.All the four reviewed guidelines recommended benzodiazepines as the first line treatment for alcohol withdrawal syndrome. The association of anticonvulsivants, adrenergic alpha-2 agonists, betablockers and antipsychotics with benzodiazepines is recommended for symptom reduction in severe alcohol withdrawal syndrome. Thiamine should be administered to all patients to prevent Wernicke-Korsakoff encephalopathy. If there is any electrolytic imbalance it should be corrected.Maintaining a high level of suspicion for alcohol withdrawal syndrome is important across all clinical settings, and it should be promptly treated.Introdução: Quando os consumidores excessivos crónicos de álcool, particularmente os indivíduos com o diagnóstico de perturbação de uso de álcool, suspendem abruptamente o consumo de bebidas alcoólicas, pode surgir um quadro clínico denominado síndrome de abstinência alcoólica. Nestes casos, é necessário muitas vezes instituir tratamento farmacológico para aliviar os sintomas e prevenir as complicações da abstinência. O tratamento farmacológico da síndrome de abstinência alcoólica é utilizado em unidades especializadas no tratamento de perturbação de uso de álcool, mas também pode ser necessário em serviços médico-cirúrgicos, quando esta síndrome se manifesta em doentes com perturbação de uso de álcool internados por patologias orgânicas.Métodos: Revisão de guidelines disponíveis na literatura sobre tratamento da síndrome de abstinência alcoólica com o objetivo de determinar qual o tratamento farmacológico recomendado.Resultados: Foram analisadas as quatro guidelines sobre tratamento farmacológico da síndrome de abstinência alcoólica (National Institute for Health and Care Excellence, American Society of Addiction Medicine, World Federation of Societies of Biological Psychiatry e American Psychiatric Association), em relação às suas recomendações e evidência da eficácia dos fármacos para tratamento da síndrome de abstinência alcoólica. Esta análise foi ainda complementada pela consulta das guidelines de Maudsley.Discussão: As guidelines analisadas recomendam, como tratamento de primeira linha, o uso de benzodiazepinas. A associação de anticonvulsivantes, agonistas adrenérgicos alfa-2, betabloqueantes e antipsicóticos com benzodiazepinas está recomendada para controlo sintomático em quadros de privação mais exuberantes. É recomendado administrar tiamina para profilaxia da encefalopatia de Wernicke-Korsakoff a todos os doentes. Caso existam desequilíbrios hidroelectrolíticos, estes deverão ser corrigidos.Conclusão: É fundamental manter um nível elevado de suspeita para o eventual aparecimento da síndrome de abstinência alcoólica em todos os contextos clínicos. Nesses casos, importa saber intervir precocemente.

Restless legs syndrome (RLS) is a chronic sensorimotor disorder, with a negative impact in the quality of life and sleep architecture. Despite its reported high prevalence, remains under-recognized and under-treated. The diagnosis is based on the presence of four essential criteria, three supportive clinical features, and other three associated features. The primary or idiopathic RLS is the most common presentation form, but it is very important to exclude other RLS secondary forms and other differential diagnosis. The physiopathology of the idiopathic RLS remains unclear, however changes in the dopamine pathway have been proposed, and justifies the use of dopaminergic agents as first line treatment. Iron therapy, opioids, anti-epileptics (gabapentin) and benzodiazepines are others non-dopaminergic options of treatment in selected patients.
