The development of auditory and visual evoked potentials in early treated phenylketonuric children.

Brain-stem auditory evoked potentials (BAEPs) and flash visual evoked potentials (F-VEPs) were gathered from 8 early treated phenylketonuric (PKU) children in a prospective longitudinal investigation during the 1st to the 12th months after birth. No consistent differences were found in the wave morphology of evoked potentials in PKU children from that of age-matched controls. Studying the latency of some components showed that in BAEPs, wave I latency was similar to control values for the whole year, but that the I-V interpeak mean latency (I-V IPL) was always significantly longer than in controls. In F-VEPs wave N1 latency was significantly longer than in controls only at 1-2 months of age, but returned to control values at 3-4 months (when all children were on dietary therapy) and remained in this range up to the 12th month. The mean latency of the P2 wave of flash VEPs was always significantly longer in PKU children than in controls. These results show that relevant alterations in evoked potentials may be found in PKU children several months after starting dietary therapy. This suggests that information processing in the brain may be impaired for a long time, due to abnormal metabolic conditions between birth and the onset of dietary therapy.

Follow-up MR studies in Hallervorden-Spatz disease.

Follow-up magnetic resonance (MR) studies of a child affected by Hallervorden-Spatz disease were performed over a period of 3 years. The hyperintense pallidi shown in the first examination changed to a mixed intensity target-like appearance. All the patterns observed in our patient have been described in the literature but in different subjects. Our data show these findings to be different manifestations of the same disease during its evolution.

[Causes of exodontia in the Navarra Health Service-Osasunbidea: epidemiological study].

The aim of this paper is to show the causes of the dental extractions in the Navarra Health Service-Osasunbidea. For 6 months all the dental extractions carried out in the clinics of the Navarra Health Service in Pamplona were registered. Data was registered for each extraction carried out. A note was made of the age and sex of the patient, the tooth extracted and the cause of the exodontia. The causes considered were: periodontia, caries, mixed causes, orthodontia, fracture and others. 4,259 extractions were carried out; 62.1% were on men and 37.9% on women (significatively different from the general population, p < 0.0001). The average age was 53.14 years (SD = 16.77 years, 95% CI: 52.62 to 53.66 years). 49.9% of extractions were due to caries, 33.7% for periodontal reasons, 3.6% for mixed causes, 1.6% for orthodontia, 0.7% because of fracture, and 10.4% for other causes. There were statistically significant differences in the distribution by sexes of the exodontias due to periodontia (p = 0.0001), orthodontia (p < 0.0001) and other causes ((p = 0.0009). The average age of the exodontias due to periodontia, accumulated in the front teeth, was greater than that for caries (p < 0.0001), accumulated in the back teeth. The average age of the exodontias due to orthodontia was 20.16 years (p < 0.0001 with all of the other causes).
