ABSTRACT
Presentamos el caso de un paciente con enfermedad de Wilson que tuvo un comportamiento poco habitual. Previoa la aparición de las manifestaciones neurológicas, tuvo tos como único síntoma, sospechándose una discinesiarespiratoria como forma de presentación. La forma clínica de su enfermedad fue de tipo neurológico puro y sin evidencias de compromiso hepático. No hubo una respuesta satisfactoria al tratamiento instituido y la evolución fue rápida y fatal en poco tiempo.
We present a case of Wilsons disease with an unusual course. Before the onset of neurological manifestations, cough was the only symptom, suggesting a respiratory dyskinesia as the form of presentation. The disease took a purely neurological type, without signs of hepatic compromise. There was no response to medical treatment, and the evolution was rapid and fatal.

Zinc has been developed as an effective and nontoxic therapy in Wilson’s disease. Zinc salts are generally well tolerated. Mild gastrointestinal discomfort is the major observed side effect and may be dependent on the zinc salt employed. Here, we report two Wilson’s disease patients who presented with severe gastric ulceration few months after beginning treatment with zinc acetate 50 mg three times a day. Our patients were not taking any ulcerogenic drugs and had no evidence of Helicobacter pylori infection. In both patients, zinc acetate was replaced by penicillamine and proton pump inhibitor therapy was initiated with complete resolution of gastrointestinal symptoms. To our knowledge, this is the first report of zinc acetate-induced gastric ulceration, which should be looked for in Wilson’s disease patients who develop abdominal discomfort while on this drug.

Objective: The aim of this study was to evaluate whether the association of chlorhexidine with zinc acetate in dentifrices formulations could reduce the emergence of extrinsic tooth stain. As second outcome check the clinical gingival parameters. Methods: 30 volunteers were randomly divided into three groups: CHX+Z, consisting of 10 participants who used a dentifrice with 0.8% chlorhexidine gluconate and zinc acetate 1.16%; CHX group, with 10 participants who used a similar formulation dentifrice without zinc acetate, and the Placebo group also with 10 participants who used a dentifrice formulation similar but without the chlorhexidine and zinc acetate. Patients were assessed at baseline and 60 days when the indexes of plaque, gingival bleeding and staining were collected. Results: The results showed that by day 60, there was a decrease of both plaque index(PI) and the gingival index(GI) for all groups. Additionally, it was observed that both groups using dentifrice containing chlorhexidine, showed more stain than placebo. The CHX+Z group showed less stain compared to the CHX group, but the difference was not statistically significant. The difference between Placebo and Chlorhexidine Groups was statistically significant (p < 0.05) when considered the stain intensity and area plus intensity scores. The CHX+Z group was as efficient in PI and GI reduction as the CHX group. Conclusions: The association of chlorhexidine with zinc acetate showed no additional benefits regarding reducing the staining. The dentifrices containing chlorhexidine presented higher reduction of GI and PI when compared to Placebo group.
Objetivo: O objetivo deste estudo foi avaliar se a associação de clorexidina com acetato de zinco em dentifrícios poderia reduzir o aparecimento de manchas dentárias extrínsecas. Como segundo objetivo verificar os parâmetros clínicos gengivais. Materiais e métodos: 30 voluntários foram divididos aleatoriamente em três grupos: CHX + Z, composta por 10 participantes que usaram um creme dental com 0,8% de gluconato de clorexidina e acetato de zinco 1,16%; grupo CHX, com 10 participantes que usaram uma formulação de dentifrício semelhante, porém sem acetato de zinco, e o grupo do placebo também com 10 participantes que usaram uma formulação dentífrica semelhante, mas sem a clorexidina e sem acetato de zinco. Os pacientes foram avaliados no início do estudo e após 60 dias, quando foram coletados os índices de placa, sangramento gengival e manchas. Resultados: Os resultados revelaram que ao dia 60, havia uma redução em ambos os índices, de placa (IP) e do índice gengival (IG) em todos os grupos. Além disso, observou-se que em ambos os grupos que utilizou dentifrício contendo clorexidina, mostrou um maior índice de manchas maior do que o placebo. O grupo CHX + Z apresentou um índice de manchas menor em relação ao grupo
