Evaluation of parathyroid function and mineral metabolism in psychiatric patients using lithium salts.

OBJECTIVE: To evaluate parathyroid function and mineral metabolism in psychiatric patients users of lithium salts. MATERIALS AND METHODS: We measured the serum levels of calcium, ionized calcium, inorganic phosphorus, alkaline phosphatase, albumin, parathyroid hormone (PTH), urea, creatinine, 25-hydroxy-vitamin D and lithium of 35 patients diagnosed with bipolar disorder in use of lithium carbonate (LC) for at least one year (Lithium Group - LG) and 35 healthy subjects (Control Group - CG). RESULTS: The LG and CG were matched by sex and age. There was only statistic difference in relation to the levels of PTH and ionized calcium, with p < 0.004 and p < 0.03, respectively. Secondary form of hyperparathyroidism (HPT) was found in eight (22.8%) LG patients and in none of the CG. There was no correlation between lithemia, usage time and dosage of LC. CONCLUSION: Our data demonstrate that lithium may create an imbalance in the parathyroid axis, characterized by elevated levels of PTH.

Objetivo: Avaliar a função paratireoidiana e o metabolismo mineral em pacientes psiquiátricos usuários de sais de lítio. Materiais e métodos: Foram avaliados os níveis séricos de cálcio total, cálcio iônico, fósforo inorgânico, fosfatase alcalina, albumina, paratormônio (PTH), ureia, creatinina, 25-hidroxivitamina D e lítio de 35 pacientes diagnosticados com transtorno afetivo bipolar usuários de carbonato de lítio (CL) há pelo menos um ano (Grupo Lítio – GL) e 35 indivíduos saudáveis (Grupo Controle – GC). Resultados: O GL e o GC foram pareados por sexo e idade. Somente se observou diferença estatística em relação aos níveis de PTH e cálcio iônico, com p < 0,004 e p < 0,03, respectivamente. Hiperparatireoidismo secundário foi encontrado em oito (22.8%) pacientes do GL e em nenhum do GC. No GL, não houve correlação entre litemia, tempo de uso e posologia do CL. Conclusão: Nossos dados demonstram que o lítio pode suscitar um desequilíbrio no eixo paratireoideano, caracterizado por níveis elevados de PTH. .

Adaptation to prostheses among patients with major lower-limb amputations and its association with sociodemographic and clinical data.

CONTEXT AND OBJECTIVE: Lower-limb amputation compromises patients' independence and autonomy, and therefore they should be referred for rehabilitation in order to adapt to prostheses and regain autonomy. The aim here was to assess adaptation to prostheses among patients with major lower-limb amputations and its association with sociodemographic and clinical data. DESIGN AND SETTING: This was a cross-sectional study in the city of Aracaju, Brazil. METHODS: The patients were identified by primary healthcare teams. The inclusion criterion was that these should be patients who underwent major lower-limb amputations of any etiology. Associations between sociodemographic and clinical variables and the adaptation to lower-limb prostheses were assessed. RESULTS: 149 patients were examined. Adaptation to the prosthesis occurred in 40% (60/149) of them, but only 62% (37/60) were using it. Adaptation occurred more often among male patients (P = 0.017) and among those who had a higher educational level (P = 0.013), with a longer time since amputation (P = 0.049) and when the etiology was trauma (P = 0.003). The result from logistic regression analysis showed that only patients with low education (P = 0.031) were significantly associated with a lower frequency of adaptation to prostheses. CONCLUSION: It was found that patients with a low educational level became adapted to the prosthesis less frequently.

CONTEXTO E OBJETIVO: A amputação de membros inferiores compromete a independência e a autonomia dos pacientes, por isso, eles devem ser encaminhados para a reabilitação para a adaptação das próteses e assim viabilizar a recuperação da autonomia. O objetivo foi avaliar a adaptação de prótese em pacientes com amputações maiores de membros inferiores e sua associação com dados sócio-demográficos e clínicos. .

TIPO DE ESTUDO E LOCAL: Estudo transversal realizado na cidade de Aracaju, Brasil. MÉTODO: Os pacientes foram identificados pelas equipes de atenção primária à saúde. O critério de inclusão foi pacientes submetidos a amputações de membros inferiores principais de todas as etiologias. Foram avaliadas as associações entre variáveis sociodemográficas e clínicas e a adaptação de próteses de membros inferiores. RESULTADOS: Foram examinados 149 pacientes. A adaptação da prótese ocorreu em 40% (60/149) deles, mas apenas 62% (37/60) a utilizavam. Adaptação ocorreu mais frequentemente em pacientes do sexo masculino (P = 0,017) e naqueles que tinham maior nível de escolaridade (P = 0,013), com maior tempo de amputação (P = 0,049) e quando a etiologia (P = 0,003) foi o trauma. O resultado da análise de regressão logística mostrou que apenas a com baixa escolaridade (P = 0,031) foi significativamente associada com uma menor frequência na adaptação de próteses. CONCLUSÃO: Verificou-se que pacientes com baixa escolaridade tiveram menor frequência de ajuste para a prótese. .
