ABSTRACT
Estudo de corte avaliando efeitos de programa de ensino-aprendizagem sobre o metabolismo e controle de níveis séricos de cálcio (Ca), fósforo (PO4), paratormônio (PTH), produto Ca x PO4, em 33 pacientes estáveis em HD, randomizados para dois grupos: Controle (n=17) e Intervenção (n=16). O grupo Controle recebeu informação sobre acesso vascular: a Intervenção sobre metabolismo de Ca, PO4 e PTH. Mudanças de conhecimento avaliadas por testes pré e pós-classe; adesão à terapia por dosagens laboratoriais seriadas. Não houve mudança significativa de conhecimento em qualquer grupo [Intervenção: 8/17 vs. 14/17 pacientes competentes no pré e pós-teste, respectivamente (P<0.001); Controle: 11/16 vs. 13/16 pacientes competentes, respectivamente (P<0.001)]. Houve redução de PO4 e produto Ca x PO4 entre tempos 0 e 1 em ambos os grupos e entre tempos 1 e 2 no grupo Controle. Concluiu-se que o programa não induziu mudança de conhecimento ou comportamento e que os programas de ensino-aprendizagem para renais crônicos devem ser contínuos.
This cohort study evaluated the effects of an educational program about metabolism and control of serum levels of calcium (Ca), phosphorus (PO4), parathormone (PTH), Ca x PO4 product on 33 stable patients on hemodialysis. Patients were randomized into two groups: control (n=17) and intervention (n=16). The control group received information on vascular access. The intervention group was informed about Ca, PO4 and PTH metabolism. The changes in knowledge were evaluated using tests. Treatment compliance was assessed by serial laboratory tests. No significant change was observed in their knowledge [intervention: 8/17 vs. 14/17 competent patients before and after class, respectively (P<0.001); control: 11/16 vs. 13/16 competent patients, respectively (P<0.001)]. A reduction was observed in PO4 and Ca x PO4 product between time 0 and 1 in both groups and between time 1 and 2 in the control group. The program did not induce changes in knowledge or behavior. In conclusion, chronic renal patients should be offered continuous educational programs.

Existió reducción de PO4 y producto Ca x PO4 entre momentos 0 y 1 en ambos grupos y entre momentos 1 y 2 en el grupo Control. El programa no indujo cambios de conocimiento o comportamiento. Los programas de enseñanza-aprendizaje para enfermos renales crónicos deben ser continuos.

Hypokalemic periodic paralysis is a rare life-threatening syndrome, potentially reversible when detected at an early stage. Hypokalemia may also occur in other conditions characterized by muscle weakness. Acute myopathy associated with thyrotoxicosis has been described in Asian populations, although it seldom affects Caucasians or African-Americans. It can be difficult to recognize in western populations. Acute recurrent episodes of flaccid paralysis, symmetrically affecting the proximal muscles of the lower limbs, either following strenuous physical activity or carbohydrate overindulgence, is the usual presentation. Hypokalemia seems to result from transcellular shifts of potassium rather than losses. A case of thyrotoxic hypokalemic periodic paralysis occurring in a young Caucasian male diagnosed with Graves' disease is reported.
