Vigabatrin-associated brain abnormalities on MRI and other neurological symptoms in patients with West syndrome.

OBJECTIVES: Report a series of children with West syndrome (WS) treated with vigabatrin (VGB) who developed characteristic MRI alterations. In the majority, these adverse events were asymptomatic; however, some of the patients developed movement disorders and acute encephalopathy. METHODS: This is a retrospective analysis of our epilepsy clinical and EEG database of 288 patients with WS seen between 2014 and 2020. All patients who received VGB alone or with concomitant therapies, such as adrenocorticotropic hormone (ACTH), high-dose oral corticosteroids, ketogenic diet, valproate, levetiracetam, or topiramate, were evaluated. RESULTS: In 44 of 288 patients with WS receiving VGB, MRI findings compatible with VGB-associated brain abnormalities were identified; median age at diagnosis was 6.29 months (range, 2 weeks to 11 months). The etiology of WS with vigabatrin-associated brain abnormalities on MRI (VABAM) was unknown in 22 (52.27%), genetic in seven (15.9%), genetic-structural in three (6.8%), structural malformative in three others (6.8%), and structural acquired in eight patients (18.2%). Vigabatrin-associated brain abnormalities on MRI was asymptomatic in 25 of 44 patients. Ten of 44 (22.7%) infants were reported to have had a movement disorder (choreoathetosis, dystonic posturing). Nine of 42 infants exhibited progressive psychomotor deterioration associated with signs and symptoms of encephalopathy. CONCLUSION: MRI abnormalities were observed in infants treated with VGB and they appeared to be dose dependent. In our study common locations for MRI abnormalities included globi pallidi and brainstem, followed by thalami and dentate nuclei. Risk factors for the development of VABAM may include age younger than 11 months and higher VGB dose of VGB (>165 mg/kg/day). Vigabatrin-associated brain abnormalities on MRI usually resolved following VGB discontinuation, probably after a period of 3 months.

Humanization in mental health plans in Spain. / La humanización en los planes de salud mental en España.

INTRODUCTION: Mental health (MH) care has important challenges, especially in the field of humanization. Our objectives were to identify the humanization measures in MH plans of the Spanish autonomous communities (CCAA) and the priorities to be developed in this area. MATERIAL AND METHODS: A large and multidisciplinary group of people involved in MH care participated in a consensus, according to a modified Delphi method, based on «design thinking¼, in three phases: (1) identification of humanization measures in MH plans of CCAA; (2) analysis of the implementation of these measures; and (3) identification of humanization priorities in MH. RESULTS: Fourteen of the 17 CCAA have current MH plans. They contained four types of humanization measures: (1) improvement of the quality of care; (2) promotion of user participation; (3) campaigns against stigma and discrimination; (4) caring for especially vulnerable people. Implementation of measures ranged from 6.3% (i.e.: specific budget) to 100%, with an average of 64.1%. We identified priority issues, operationalized in 5 proposals: (1) information campaigns; (2) multidisciplinary meeting forums; (3) platforms of support entities; (4) strategies on MH education; (5) humanization in study plans. CONCLUSIONS: Some MH plans include humanization among their objectives, but partially. The implementation of humanization proposals such as those identified in this study is essential to achieve a high-quality MH care.

Vitamin B12 Deficiency and West Syndrome: An Uncommon but Preventable Cause of Neurological Disorder. Report on Three Cases, One of Them with Late Onset during Vitamin B12 Treatment.

Vitamin B12 is a water-soluble vitamin that plays a fundamental role as an essential cofactor for two enzymes responsible for the production of succinyl-CoA and methionine. Vitamin B12 deficiency can occur in infants and may be related to the breastfeeding mother's adherence to a vegan diet or somatic diseases in the mother. It should be differentiated from inborn errors of vitamin B12 metabolism. Herein, we report the cases of three infants with West syndrome; all three were breastfed by mothers who followed a strict vegan diet. In one of the three infants, West syndrome developed during treatment with vitamin B12 and normalization of the vitamin B12 level. Early treatment and replacement therapy are worthwhile to prevent serious neurological problems and to improve the patient's clinical course.
