Cerebrospinal fluid white blood cell counts and lactic acid dehydrogenase in Enterovirus type 71 meningitis.

An outbreak of aseptic meningitis involving 36 children is described. Enterovirus type 71, a recently recognized cause of central nervous system and systemic illness in children, was found to be the responsible agent. On initial lumbar puncture, cerebrospinal fluid (CSF) polymorphonuclear (PMN) cell predominance was seen in 64%, and greater than 200 CSF white blood cells (WBC)/mm3 was seen in 25% of these patients. Fifty-four per cent of the patients subjected to repeat lumbar puncture and a significant rise in the number of CSF WBC/mm3, the majority with the maintenance of a PMN cell predominance. The CSF white blood cell findings of individual patients did not allow for differentiation from patients concurrently seen with bacterial meningitis. Both initial and serial measurements of CSF lactic acid dehydrogenase reliably distinguished these two groups of patients.

Analysis of the use of Dycal with gutta-percha points as an endodontic filling technique.

The use of Dycal combined with gutta-percha cones as a permanent root canal filling material was analyzed. The following experiments were performed: 1. In vitro microscopic analysis of Dycal's adaptation in the dentin wall--gutta-percha cone interphase. 2. Study of the duration period of alkalinity. 3. Clinical and radiograhic posttreatment, inspection and evaluation, and follow-up. The results obtained in these studies showed: 1. There was correct adaptation and adherence of the material. 2. The alkalinity persisted up to 8 months after mixing. 3. There was clinically good postoperative tolerance. 4. Clinical and radiographic success was found in 90 percent of the cases in the treatment of normal vital pulps, vital inflamed pulps, and pulpless teeth with or without areas.

Microscopic study of standardized gutta-percha points.

Eleven brands of gutta-percha cones were analyzed with the optical microsocpy, showing deformations in the apical thirds which would not allow the correct adaptation of them in the apical section of the root canal.

Differentiation of orbital cellulitis from preseptal cellulitis by computed tomography.

Computed tomography (CT) was used in the management of four patients with periorbital inflammation. These patients were selected for CT scanning because of the difficulty, on clinical examination alone, in determining the degree of orbital disease. The CT scans confirmed the presence and defined the location of an orbital abscess in three patients and eliminated the presence of an abscess in the fourth. On the basis of this experience, CT scanning is recommended in the evaluation of children with periorbital inflammation in whom proptosis, ophthalmoplegia, or loss of visual acuity develops, or in whom severe eyelid edema prevents adequate eye examination.

Withdrawal from methadone maintenance. Rate of withdrawal and expectation.

One hundred twenty-seven successfully methadone-hydrochloride-maintained patients were randomly assigned to one of the following four groups and studied for 30 weeks: (1) known maintenance-patients were maintained on methadone under open conditions; (2) blind maintenance-patients were maintained on methadone under double blind conditions; (3) rapid withdrawal-patients were withdrawn under double-blind conditions at a rate of 10% of initial dose per week; (4) gradual withdrawal-patients were withdrawn under double-blind conditions at a rate of 3% of initial dose per week. Differences in dropout rates, illicit drug use, symptoms scores, and requests for study interruption indicate that withdrawal from methadone maintenance should be carried out at approximately 3% of initial dose per week. Better patient preparation also is indicated to reduce the effects of expectation.

[Use of thermoplasticized gutta-percha in retrograde obturation].

In 29 teeth, apicoectomies with retrograde instrumentation and retrofilling with low temperature thermoplasticized gutta-percha were performed. Nineteen of them were clinically an radiographically evaluated, showing the following average rate: successes 84.2% (16 cases), failures 10.5% (2 cases) and incomplete healing 5.2% (1 case). The observation period varied from 12 to 41 months. The use of retrograde instrumentation an retrofilling with thermoplasticized gutta-percha is suggested as a useful method in surgical procedures.
