Primary palmar hyperhidrosis in children and adolescents may be severe enough to affect school and physical activities, causing emotional problems, stress in the patient's life, and a compromised quality of life. Nine patients with palmar hyperhidrosis underwent treatment with botulinum A. Before the session, and in the 1-, 3-, 6-, 9-, and 12-month post-session follow-ups, the patients were administered the Minor test, gravimetry, the Scales of Frequency and Severity, and the Questionnaire of Quality of Life. The mean age was 11 years, with seven girls and two boys. Each patient was administered at least one treatment of botulinum toxin in the palm of the hands (75-150 U for palm), with the mean number of sessions 2.2 (range: 1-4). All sessions in the patients resulted in drying of the hands, with a mean duration of effect of 7 months. Botulinum toxin A controls excessive sweat in the palms of children and adolescents who have primary palmar hyperhidrosis, with an improvement in the quality of life. The therapy is safe and effective in this pediatric group and can be considered before surgical interventions.
A presente investigação permitiu determinar a prevalência de Dirofilaria immitis em cães alojados no Canil da Prefeitura Municipal de Guaratuba, Paraná, por meio de três diferentes técnicas hematológicas: a) Exame direto do sangue a fresco, b) Método de KNOTT (1939) modificado, c) Canine Heartworm Antigen Test® (Snap Test). Foram avaliados 111 machos e 102 fêmeas, apreendidos e recolhidos pelo Serviço de Vigilância Municipal de Guaratuba entre maio de 2001 e dezembro de 2002. As amostras de sangue revelaram dois cães positivos para D. immitis. O primeiro reagiu de forma positiva aos três testes laboratoriais utilizados, enquanto o outro cão acusou positividade apenas no Snap Test, caracterizando dirofilariose oculta. A prevalência foi de 0,94% de cães infectados por Dirofilaria immitis, de um total de 213 animais avaliados.
