Intermittent Prophylaxis In Febrile Seizure With Oral Diazepam: Study Of 82 Cases [profilaxia Intermitente Com Diazepam Via Oral Na Convulsao Febril: Estudo De 82 Casos]

We present our results of intermittent prophylaxis with oral diazepam in febrile seizures. We treated 82 patients aged between 3 months and 5 years. They have had simple or complex febrile seizures. Recurrence occurred in 22 patients (26%), none had a long-lasting febrile convulsion. Transient side effects occurred in 21.95% of the cases. We conclude that diazepam is a safe and effective drug for prophylaxis of febrile seizures when used as soon as any sign of illness appears. We suggest, however, that the administration of the drug should be indicated if the child presents at least one consistent predictor of risk of recurrent febrile seizures.54219720

Lamotrigine In Epilepsy Of Difficult Control In Children [lamotrigina Em Epilepsia De Dificil Controle Na Infancia]

We present the results of a prospective, add-on, open trial with lamotrigine in 30 pediatric patients (aged 1 year 4 months to 16 years 8 months - average 6.5 years) with refractory seizures. The mean follow-up period was 25.7 months. Patients were classified according to the major epileptic syndrome. The best results obtained were patients with symptomatic partial epilepsy and myoclonic-astatic epilepsy. Fifteen patients had at least 50% reduction in seizure frequency. Fourteen patients had side effects; 5 patients who were taking valproate simultaneously exhibited skin rash after lamotrigine. This drug was withdrawn in 4 children and 1 patient had a rash that subsided with valproate withdrawal. The other side effects were transient and disappeared spontaneously with lamotrigine dose reduction or with valproate withdrawal.2211111

Mineral composition and dry mass production of the corn plants in response to phosphorus sources and aluminum concentration

The corn plants were evaluated with different phosphate fertilizer sources and aluminum (Al) concentrations in a sandy substrate. A totally randomized experiment design was set up with two corn plants in the pots containing 2 kg of a sandy substrate, two phosphate sources (Triple Super Phosphate - TSP or Arad Phosphate - AP) and four Al concentrations. When Al concentrations increased, pH (CaCl2) substrate values decreased. There was an increase in the calcium and phosphorus contents in the sandy substrates that received the TSP and AP sources. The calcium, magnesium, phosphorus, and potassium concentrations of the corn plant's shoot were higher in the TSP than without P and AP sources. When the Al concentration increased, the concentration values of the former elements decreased. The dry mass production of the corn plants responded positively to P sources. As the Al concentration increased, the dry mass values decreased significantly in the TSP source.<br>Foram avaliadas plantas de milho submetidas a diferentes fontes de fertilizantes fosfatados e diferentes concentrações de alumínio em um substrato de areia. O experimento foi conduzido com duas plantas por vaso contendo 2 kg de areia, duas fontes de fósforo (Fosfato Supertriplo -TSP ou Fosfato de Arad -AP) e quatro concentrações de Al. Com o aumento das concentrações de Al houve diminuição dos valores de pH (CaCl2) do substrato. Os valores de cálcio e fósforo aumentaram no substrato nos tratamentos com TSP e AP. As concentrações de cálcio, magnésio, fósforo e de potássio das plantas de milho foram maiores em TSP do que nos tratamentos sem P ou com AP. Como o aumento da concentração de Al observou-se redução na concentração de cálcio, magnésio, fósforo e de potássio nas plantas. A produção de massa seca da parte aérea respondeu positivamente com as fontes de P. Com o aumentou da concentração de Al os valores de massa seca diminuíram significativamente com TSP
