Aim: To compare 24-month pulp health outcomes of partial caries removal (PCR) and total caries removal (TCR) with composite restoration in primary molars. Methods: 48 children aged 3-8 years with at least one molar with a deep carious lesion were included. 120 teeth were randomized to control (TCR; n = 54; 69% class II) and test (PCR; n = 66; 63% class II) groups. Total absence of carious tissue was confirmed using a blunt-tipped probe in the TCR group. For PCR, excavation was stopped when hardened, dried dentin with a leathery consistency was achieved. Pulpotomy was performed in cases of pulp exposure. Results: Pulp exposure occurred in 2 and 27.5% of teeth treated with PCR and TCR, respectively (p < 0.01). The operative time was significantly higher for TCR than PCR. Success rates were 92 and 96% in the PCR and TCR groups, respectively (p = 0.34). The success rate tended to be lower in occlusoproximal (92%) than in occlusal (100%) lesions (p = 0.08). Conclusion: The clinical and radiographic success rates of PCR and TCR in primary teeth with deep carious lesions were high and did not differ significantly, indicating that PCR is a reliable minimally invasive approach in primary teeth and that the retention of carious dentin does not interfere with pulp vitality. Moreover, PCR provided other clinically relevant advantages over TCR, especially lower incidence of pulp exposure and lower operative time.

-Recurrent episodes of abdominal pain are common in childhood. Among the diagnostic possibilities are migraine and abdominal epilepsy (AE). AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since the age of 4. The pain was followed by cry, fear and occasionally secondary generalization. MRI showed tumor in the left temporal region. As a differential diagnosis, we report a 10 year-old boy who had long episodes of abdominal pain accompanied by blurring of vision, vertigo, gait ataxia, dysarthria, acroparesthesias and vomiting. He received the diagnosis of basilar migraine. In our opinion, AE is part of a large group (partial epilepsies) and does not require a special classification. Pediatric neurologists must be aware of these two entities that may cause abdominal pain. RESUMO -Episódios recorrentes de dor abdominal são freqüentes na infância e entre as causas neurológicas há migrânea e epilepsia abdominal (EA). EA é uma síndrome que consiste de episódios paroxísticos de dor abdominal associada à alteração de consciência, anormalidades eletrencefalográficas e boa resposta à terapia anticonvulsivante. Apresentamos uma menina de 6 anos que tinha desde os 4 anos episódios de curta duração de dor abdominal, seguidos por choro, medo e ocasional generalização secundária. A RM mostrou a presença de um tumor em região temporal esquerda. Como diagnóstico diferencial, apresentamos um menino de 10 anos que há 12 meses referia episódios de dor abdominal de longa duração acompanhados por turvação visual, vertigem, marcha atáxica, disartria, acroparestesia e vômito, recebendo posteriormente o diagnóstico de migrânia basilar. Em nossa opinião, EA faz parte de um grande grupo (epilepsias parciais) e não requer uma classificação especial. O neuropediatra deve estar alerta para essas duas entidades que podem cursar com dor abdominal. PALAVRAS-CHAVE: crises parciais, tumor do lobo temporal, migrânea basilar, dor abdominal e epilepsia sintomática.

The neuropsychological features of children with temporal lobe epilepsy are not yet well defined. The aim of this study was to identify the neuropsychological deficits in children with temporal lobe epilepsy. We evaluated 25 patients and compared them with 25 normal children. All children underwent a comprehensive neuropsychological assessment. We found a significant difference in favor of the control group in the following measures: IQ; forward digit; Trail Making Test for Children B; Wisconsin Card Sorting Test; block design; Boston naming test, verbal fluency; and Wide Range Assessment of Memory and Learning verbal learning, visual learning, verbal memory, visual memory, delayed recall of verbal learning, delayed recall of stories, and recognition of stories. Our findings show that children with temporal lobe epilepsy present with several neuropsychological deficits, despite normal IQ. These findings point to a dysfunction of cerebral areas other than temporal lobe, particularly the frontal lobes.

-The objective of this study was to evaluate the safety and efficacy of clobazam in children with refractory focal epilepsy. We investigated 100 consecutive patients concerning etiology of epilepsy, previously used antiepileptic drugs, seizure frequency and adverse events. Clobazam was introduced as add-on therapy in patients with previous failure of at least two monotherapies. Mean age was eight yearsold and 39 patients were girls. Clobazam mean dosage was 23.6 mg/day. Mean use of clobazam was 18.6 months. Twenty-two patients had adverse events. Twenty-six patients became seizure-free, 11 had an improvement of >75% and in 58 there was no modification in seizure frequency. Five patients had an increase in seizure frequency. Clobazam efficacy lasted for more than one year in 42% of the seizure-free patients. Clobazam seems to be safe and effective in the treatment of focal epilepsy in childhood and should be considered in patients with refractory seizures.KEY WORDS: clobazam, focal epilepsy, childhood. Eficácia do clobazam como terapia adjuvante em crianças com epilepsia focal refratáriaRESUMO -O objetivo deste estudo foi avaliar a segurança e eficácia do clobazam em crianças com epilepsia focal refratária. Nós investigamos 100 pacientes consecutivos em relação à etiologia da epilepsia, uso prévio de drogas anti-epilépticas, freqüência de crises e eventos adversos. Clobazam foi introduzido como terapia adjuvante em pacientes que não responderam a pelo menos duas monoterapias. A idade média foi 8 anos e 39 pacientes eram do sexo feminino. A dose média de clobazam foi 23,6 mg/dia. O uso médio de clobazam foi por 18,6 meses. Vinte e dois pacientes tiveram eventos adversos. Vinte e seis pacientes tornaram-se livres de crises, 11 tiveram melhora > 75% e em 58 não houve modificação na freqüência de crises. Cinco pacientes tiveram aumento na freqüência de crises. A eficácia do clobazam permaneceu por mais de um ano em 42% dos pacientes sem crises. Clobazam parece ser seguro e eficaz no tratamento de epilepsia focal na infância e deve ser considerado em pacientes com crises refratárias. PALAVRAS-CHAVE: clobazam, epilepsia focal, infância.
