BackgroundPediatric medications may possess a high erosive potential to dental tissues due to the existence of acid components in their formulations. The purpose was to determine the erosive and cariogenic potential of pediatric oral liquid medications through the analysis of their physicochemical properties in vitro.MethodsA total of 59 substances were selected from the drug reference list of the National Health Surveillance Agency (ANVISA), which belong to 11 therapeutic classes, as follows: analgesics, non-steroidal anti-inflammatory, corticosteroids, antihistamines, antitussives, bronchodilators, antibacterials, antiparasitics, antiemetics, anticonvulsants and antipsychotics. Measurement of pH was performed by potentiometry, using a digital pH meter. For the Total Titratable Acidity (TTA) chemical assay, a 0.1 N NaOH standard solution was used, which was titrated until drug pH was neutralized. The Total Soluble Solids Contents (TSSC) quantification was carried out by refractometry using Brix scale and the analysis of Total Sugar Content was performed according to Fehling’s method. In addition, it was analyzed the information contained in the drug inserts with regard to the presence of sucrose and type of acid and sweetener added to the formulations.ResultsAll drug classes showed acidic pH, and the lowest mean was found for antipsychotics (2.61 ± 0.08). There was a large variation in the TTA (0.1% - 1.18%) and SST (10.44% - 57.08%) values. High total sugar contents were identified in the antitussives (53.25%) and anticonvulsants (51.75%). As described in the drug inserts, sucrose was added in 47.5% of the formulations, as well as citric acid (39.0%), sodium saccharin (36.4%) and sorbitol (34.8%).ConclusionThe drugs analyzed herein showed physicochemical characteristics indicative of a cariogenic and erosive potential on dental tissues. Competent bodies’ strategies should be implemented in order to broaden the knowledge of health professionals, drug manufacturers and general consuming public about the risks from the consumption of medicines potentially harmful to dental tissues.
Increased fibrinogen was prevalent in the study population and was associated with ultrasensitive C-reactive protein and the presence of four or more cardiovascular risk factors; it should be included in the assessment of individuals at risk.
objectives: Discuss neuropsychiatric aspects and differential diagnosis of catatonic syndrome secondary to systemic lupus erythematosus (SLE) in a pediatric patient. Methods: Single case report. result: A 13-year-old male, after two months diagnosed with SLE, started to present psychotic symptoms (behavioral changes, hallucinations and delusions) that evolved into intense catatonia. During hospitalization, neuroimaging, biochemical and serological tests for differential diagnosis with metabolic encephalopathy, neurological tumors and neuroinfections, among other tests, were performed. The possibility of neuroleptic malignant syndrome, steroid-induced psychosis and catatonia was also evaluated. A complete reversal of catatonia was achieved after using benzodiazepines in high doses, associated with immunosuppressive therapy for lupus, which speaks in favor of catatonia secondary to autoimmune encephalitis due to lupus. conclusion: Although catatonia rarely is the initial clinical presentation of SLE, the delay in recognizing the syndrome can be risky, having a negative impact on prognosis. Benzodiazepines have an important role in the catatonia resolution, especially when associated with parallel specific organic base cause treatment. The use of neuroleptics should be avoided for the duration of the catatonic syndrome as it may cause clinical deterioration. resUMo objetivos: Discutir aspectos neuropsiquiátricos e o diagnóstico diferencial da síndrome catatônica secundária a lúpus eritematoso sistêmico (LES) em paciente pediátrico. Méto-dos: Relato de caso individual. resultado: Adolescente do sexo masculino com 13 anos de idade iniciou, após dois meses de diagnosticado com LES, quadro psicótico (alterações comportamentais, alucinações e delírios) que evoluiu para franca catatonia. Durante internação hospitalar foram realizados, entre outros, exames de neuroimagem, bioquímicos e sorologias para diagnóstico diferencial com encefalopatia metabólica, tumores neurológicos e neuroinfecções. Foi avaliada também a possibilidade de síndrome neuroléptica maligna, psicose e catatonia induzida por corticoides. Houve reversão completa da catatonia após o uso de benzodiazepínico em altas doses associado à terapia imunossupressora para o lúpus, o que fala a favor de uma catatonia secundária a uma encefalite autoimune de base lúpica.
