Radiographic evaluation of periradicular repair after endodontic treatment of dog's teeth with induced periradicular periodontitis.

Eighty-four root canals of premolars from six dogs were left open for 7 days, and then sealed and followed for 45 days until periradicular periodontitis developed. The root canals were then treated endodontically using 5.25% sodium hypochlorite as the irrigating solution. After instrumentation, all root canals were filled with a calcium hydroxide-based antibacterial dressing (Calen PMCC or Calasept) that was left in place for 30 days. After this period the root canals were filled with gutta-percha cones and a root canal sealer (Sealapex or AH Plus)--group I: Calen PMCC + Sealapex; group II: Calasept + Sealapex; group III: Calen PMCC + AH Plus; and group IV: Calasept + AH Plus. Periapical radiographs of the teeth were made after root canal filling and after 90, 180, 270, and 360 days. Radiographic images were digitalized by scanning, and the Mocha program was used to measure the periapical lesions. Analysis showed that the lesions of groups I to III were statistically similar reduction in size, whereas group IV had a smaller reduction in lesion size (p < 0.05).

[Aicardi syndrome: case report].

We report a case of Aicardi syndrome in a female child with 2 month old, ocular abnormalities "chorioretinal lacunae", flexion in spasms, hipsarrhythmic "split brain", callosal agenesis referred to Service of Neuropediatric and Neurophysiology of Base Hospital of São José do Rio Preto, SP, Brazil.

[Migration in different sorts of work, unemployment and retirement of 81 epileptic patients. 3 years of ambulatory follow-up].

This study aims to assess epileptic patients migration in different sorts of paid/non paid and formal/informal work, unemployment and retirement. Eighty one epileptic patients were evolutively analyzed (cohort) at the Epilepsy Department of Hospital de Base, Medical School, São José do Rio Preto, Brazil. The epileptic percentages in different sorts of work, in March 1996 was compared with the one after three-year follow-up period in March 1999. There were no statistical significant changes among the same sorts of work in this period. However, there were intense migrations in relation to different sorts of work. Paid work showed migration to unemployment and retirement. This research shows the significant migration of epileptic patient either to some kind of a less qualified work or to some social security dependence as well as to early retirement.

[Duration and age range of epilepsy and its correlation with work: prospective ambulatory study in 379 epileptics].

This study aims to evaluate, prospectively, the relationship of the active epilepsy length and the work, of the 379 out-patients from Hospital de Base, São José do Rio Preto. Epilepsy length was subdivided into 5 time rates and by age, into 3 age-groups. There was no relationship, not considering the age of patient among the epilepsy length and the work, but young patient (14 at 29 years old) and with recent epilepsy (length of 0 at 5 years) lost more work than the adult and elderly epileptic.

[Epileptic syndromes and seizures and their relationship with work: a prospective ambulatory study in 412 epileptic patients].

This study aims to evaluate, prospectively, the epileptic syndromes and seizures types upon work based on a sample of 412 out-patients from Hospital de Base, São José do Rio Preto, SP, Brazil. It was observed that the epileptic syndromes were significant in relation to the patients' labor skills (p= 0.001): the idiopathic syndromes showed less prejudiced, while the symptomatic was more. The seizures types also had some influence in relation to the patients' labor skills (p=0.016): the generalized non-convulsive seizures had no involvement; the simple partial and the non-classified had moderately involvement; and the simple partial seizures evolving to complex and tonic-clonic generalized were the seizures which mostly have taken the patients away from work. The seizure severity was also analyzed.

A comparison of molar root canal preparation using stainless-steel and nickel-titanium instruments.

Fifty-four extracted human mandibular molars were embedded and sectioned at two levels. The reassembled mesial root canals were prepared with stainless-steel hand K-files (Flexofiles) and either Nitiflex or Mity nickel-titanium hand K-files using a push-pull anticurvature filing technique. Each of the three experimental groups contained 36 mesial canals randomly distributed. Superimposed pre- and post-instrumentation cross-sectional root images were magnified using a stereomicroscope and transferred to a computer for measurement and statistical analysis. The direction and extent of canal center movement were evaluated. At the apical level, the groups produced no significant difference of direction of canal center movement. In cervical sections, all groups tended to move in a distolingual direction. The three groups, however, produced no significant difference in the cervical sections in the extent of canal center movement. In apical sections, Nitiflex produced the least canal center movement.

[Age of appearance and disappearance of rolandic spikes of 160 children treated in ambulatory. Actuarial study].

UNLABELLED: This study aims to determine the age at which the rolandic spikes (RS) appear and disappear in routine EEGs. METHOD: It has been carried out a hospital based prospective study of 412 EEGs records of 160 children who had been assisted at the neuropediatric out-patient department during the period between March, 1989 and March, 1998. Recordings were made on 8-channel instruments and 10/20 system has been to place the electrodes. The children have been divided into 4 groups, according to their age (1 to 4; 5 to 8; 9 to 16; 1 to 16), and the actuarial curve method has been used to show the disappearance of the rolandic spikes. RESULTS: RS distribution between boys and girls has been 64/36 ratio. RS have been found at average age of 7 years (boys, 7.2 and girls, 6.6). In a small group of children with normal EEGs previous to the RS appearance, the average age has been 6.8 years old. After this 7-year follow up period, the percentage of patients free from RSs was 60% for 1 to 4 year old group at admission; 84% for the 5 to 8 year old group and for the 9 to 16 year old group. For the total group (1 to 16 year old), the percentage of those free from RSs after this 7 year follow up period was 78%. CONCLUSION: This study shows that RSs appear at the average age of 7 years old, and are likely to disappear up to the end of a 7-year follow up period, independently on the appearance age.
