Atividade epiléptica focal durante sono induzido na síndrome de Lennox-Gastaut secundária

Quinze pacientes com síndrome de Lennox-Gastaut secundária foram submetidos a exames clínicos e eletrencefalográficos mensais por períodos de tempo que variaram de 1 a 9 anos. Os exames eletrencefalográficos foram realizados durante sono induzido por barbitúrico. Doze pacientes apresentaram atividade epiléptica focal. No presente trabalho descrevemos a localização, morfologia e freqüência dos paroxismos epilépticos focais.

Hiperplasia nodular focal do fígado: apresentação de um caso e revisão da literatura

Neste trabalho apresentamos um caso de hiperplasia nodular focal que foi diagnosticado aos seis anos de idade e que está sendo acompanhado até o momento presente. Para o diagnóstico foram imprescindíveis as técnicas de imagem, tendo importância de realce a cintilografia hepatoesplênica e a tomografia computadorizada. Apresentamos, também, revisão da literatura sobre o assunto.

Padrões morfológicos de lesão glomerular e correlação com achados clinicolaboratoriais de 43 crianças com síndrome nefrótica

OBJETIVOS: Avaliar a associação entre os parâmetros clinicolaboratoriais e alteração morfológica de biópsias renais em crianças com síndrome nefrótica. MÉTODOS: Os dados foram obtidos dos prontuários médicos de 43 crianças com síndrome nefrótica submetidas a biópsia renal. RESULTADOS: Vinte e oito pacientes eram do sexo masculino (65,1%), idades entre 1,4 a 12 anos (média de 4,7±3,2). Quarenta e dois pacientes (97,7%) apresentaram edema; 83,7%, oligúria e 32,5%, hipertensão arterial. A média de proteinúria foi 15,3g/1,73m²SC/dia e 55,8% apresentaram hematúria microscópica. As biópsias renais mostraram: glomerulonefrite proliferativa mesangial (GNPM) em 37,2%, glomeruloesclerose segmentar e focal (GESF) em 27,9%, alterações glomerulares mínimas (LM) em 25,6%, glomerulonefrite membranoproliferativa (GNMP) em 7% e glomerulonefrite membranosa (GNM) em 2,3%. Vinte e seis pacientes (60,5%) apresentaram resistência ao corticosteróide. Idade, sexo, hipertensão arterial, oligúria, uréia e creatinina séricas não mostraram diferenças estatísticas significativas entre os pacientes com GNPM, GESF e LM. Os pacientes com GNPM e GESF apresentaram maior freqüência de hematúria microscópica (p < 0,003 e p < 0,03; respectivamente). Os pacientes com GESF apresentaram maiores níveis de proteinúria (p < 0,01 versus LM e p < 0,05 versus GNPM). Os pacientes com LM apresentaram sensibilidade ao corticosteróide (p < 0,001 versus GESF e p = 0,047 versus GNPM). CONCLUSÕES: Sexo, idade, presença de hipertensão arterial ou oligúria e níveis séricos de uréia e creatinina não auxiliaram na diferenciação entre pacientes com GNPM, GESF e LM. Os pacientes com LM apresentaram sensibilidade a corticosteróides e menos probabilidade de apresentar hematúria microscópica. Pacientes com GESF apresentaram maiores níveis de proteinúria.

Paulista registry of glomerulonephritis: 5-year data report

Background. The Paulista Registry of Glomerulopathies was created in May 1999 and comprises several centres of São Paulo, the most populous Brazilian State, that concentrates people from all regions of the country who look for health care.Methods. This report includes data from 2086 patients from Brazil submitted to renal biopsy due to the presumed diagnosis of glomerular diseases, registered prospectively since May 1999 until January 2005. Data were collected by the integrants of the 11 centres involved, utilizing a standardized questionnaire.Results. The mean age of the patients was 34.5 +/- 14.6 years. Primary glomerular diseases were more frequent in males (55.1%) than in females; on the other hand, secondary glomerular diseases were more frequent in females (71.8%). The most common clinical presentation was nephrotic syndrome and the frequency of hypertension, at this time, was 55.5%. There was a predominance of indication of biopsies in the third, fourth and fifth decades of life. The most common primary glomerular diseases were focal and segmental glomerulosclerosis (29.7%), followed by membranous nephropathy (20.7%), IgA nephropathy (17.8%), minimal change disease (9.1%), membranoproliferative glomerulonephritis (7%), crescentic glomerulonephritis (4.1%), advanced chronic glomerulopathy (4%), non-IgA mesangial glomerulonephritis (3.8%), diffuse proliferative glomerulonephritis (2.5%), focal segmental proliferative glomerulonephritis (1%) and others (0.3%). The most frequent secondary glomerular disease was lupus nephritis, corresponding to 66.2% of the cases, followed by post-infectious glomerulonephritis (12.5%), diabetic nephropathy (6.2%), diseases associated to paraproteinaemia (4.9%), hereditary diseases (4.6%), vasculitis (3.2%), malignancies (0.9.%), secondary focal segmental glomerulosclerosis (0.6%) and others (0.9%).Conclusion. Focal segmental glomerulosclerosis was the most frequent primary glomerular disease, followed by membranous nephropathy and IgA nephropathy. Lupus nephritis predominated over all the other secondary glomerular diseases.

Systemic hypertension in patients with glomerulonephritis

Although systemic hypertension is very common in patients with glomerulonephritis there is a dispute if this alteration is consequence of the glomerulonephritis per se or is a consequence of the renal failure secondary to the glomerular lesion. With the aim to analyze the factors associated with systemic hypertension, 196 patients with different forms of nephritis were studied. The systemic arterial pressure was measured by standard sphygmomanometer, renal function was evaluated by the determination of the serum creatinine concentration or creatinine clearance. The diagnosis of the type of glomerulonephritis was made on the basis of an examination of kidney biopsy specimens. The prevalence of arterial hypertension among patients with glomerulonephritis was 62.7%. The hypertensive patients were older (hypertensive = 30.6 ± 12.8; normotensive = 25.4 ± 1.6 years; P = 0.03). The prevalence of arterial hypertension was lower in patients with minimal glomerular lesion (12.5%), though their ages were also lower (18.1 ± 3.6 and 29.1 ± 1.03 years; P = 0.03). Arterial hypertension did not correlate with the serum levels of creatinine and albumin; creatinine clearance and 24-h proteinuria. In conclusion: In the patients with glomerulonephritis, the presence of arterial hypertension was associated with a higher mean age whereas the intensity of proteinuria, the level of renal function or the type of glomerulonephritis was not different between the two groups.

Técnica do grupo focal como método de avaliação do conhecimento de adolescentes sobre saúde bucal

This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique. The study was conducted at three public schools in the city of Araçatuba, São Paulo State, Brazil, with ten students in each. In order to conduct the focus groups, the following words, which featured high error levels, were addressed in survey questions on oral health: oral health; plaque, permanent teeth; fluoride; gum bleeds?; dental floss; transmission of cavities. During the discussions in the focus groups, it was observed that many teenagers were surprised at the situation to which they were submitted and at the topic they were discussing. The word 'oral health' was associated with the condition of cleanliness of the oral cavity, not identifying oral health as part of general health. The term 'transmission of cavities' did not have a sufficient understanding. The term 'permanent tooth' was well understood and was associated with a type of tooth that would not be replaced. The word 'fluoride' had more association with the task of cleaning than protection of the teeth. It is concluded that the use of the focus group technique is of great importance in the interpretation of the knowledge of adolescents on oral health and the appropriateness of the terminology of questionnaires on the same subject.
