Combined sedation with oral chlordemethyldiazepam and midazolam by nasal route in third molar surgery.

AIM: This study was performed to evaluate the effects on the cardiocirculatory system, on perioperative anxiety and compliance of sedation with 2 benzodiazepines, chlordemethyldiazepam (CDDZ) a long acting oral drug for presedation and midazolam, a short acting drug, administered by nasal route to induce intraoperative sedation. METHODS: Fifty randomized patients undergoing third molar extraction at the Dental Clinic, University of Padua, were preoperatively evaluated. Anxiety was evaluated through a visual, analogue, scale (VAS) of 10 cm, a questionnaire of adjectives called interval scale of anxiety response (ISAR) and the Newman test was applied to evaluate the changes in psychomotor functions. All patients were treated with 1 ml of oral CDDZ for presedation and midazolam by the nasal route for intraoperative sedation at doses of 1 mg in Group 1 (25 patients) and 2 mg in Group 2 (25 patients). In all patients preoperative cardiocirculatory parameters were evaluated and in the first 20 min after the beginning of intervention. At the end of intervention the Newman test was reapplied, anxiety and postoperative cardiocirculatory data were reevaluated and the quality of the intervention judged in an interview made 1 week after the intervention (quality of the sedation technique, perioperative pain intensity, assumption of analgesic drugs, swelling, amnesia etc. after intervention). RESULTS: The treatment with 1 mg CDDZ + 2 mg midazolam by nasal route is the best association to slightly attenuate intra- and postoperative cardiocirculatory response, anxiety and to improve the quality of the treatment without interfering on the psychomotor response of patients at the time of the discharge. CONCLUSION: To conclude, the sedative technique employed is easily applied by the dentist, and is safe, efficacious and well tolerated by patients.

Electron-beam tomography coronary calcium scores are superior to Framingham risk variables for predicting the measured proximal stenosis burden.

Previous studies of electron-beam tomography (EBT) have correlated coronary calcium scores with simplistic visual estimates of disease severity. In a clinical trial designed to evaluate 2 treatment strategies in coronary artery disease (CAD) patients with low levels of high-density lipoprotein cholesterol, we used quantitative coronary angiography to measure composite proximal stenosis burden from the baseline coronary angiogram and assessed the traditional Framingham risk variables in 146 patients. Stenosis burden is the sum, per patient, of percent stenosis for the worst lesion found in each of 9 standard proximal coronary segments. EBT estimates of coronary calcium (Agatston score, calcium volume score) were obtained for 115 of these patients. Stenosis burden was correlated with the calcium scores and risk variables. The best traditional correlates of stenosis burden were smoking status (r = 0.31, p = 0.001), prior myocardial infarction (r = 0.24, p = 0.005), body mass index (r = 0.23, p = 0.005), pack-years smoking (r = 0.20, p = 0.05), and age (r = 0.17, p = 0.04). With adjustment for age, all these correlations improved (eg, body mass index x age [r = 0.28, p = 0.001]). In addition, total cholesterol x age (r = 0.22, p = 0.008), fibrinogen x age (r = 0.19, p = 0.03), and systolic blood pressure x age (r = 0.18, p = 0.03) became significant correlates. Spearman correlations of the calcium scores with stenosis burden were considerably greater (Agatston: r = 0.62, p <0.0001; calcium volume: r = 0.63, p <0.0001). In multivariate regression analysis, calcium score, body mass index, and history of myocardial infarction were independent correlates of stenosis burden (R(2) = 0.45). At a given point in time, the EBT coronary calcium scores are greatly superior to the Framingham risk factors in predicting the measured proximal stenosis burden. Agatston and calcium volume scores are comparably predictive of stenosis burden.

High-risk sexual behaviors among adolescents engaged through a street-based peer outreach program--(the Adolescent HIV Project).

On-the-street peer based programs can overcome barriers and successfully engage teens in HIV counseling and testing. This initiative combines on-the-street peer outreach with on-the-street HIV testing in a mobile counseling and testing van. A survey was conducted to measure HIV risk behaviors concern about HIV infection. In year one, the program engaged 1550 youth. Of these, 666 completed HIV counseling and testing. Only 18% indicated that they had not had unprotected sexual intercourse in the preceding year. Thirty-nine percent of the males and 52% of the females had caused or been pregnant. Sixty-six percent of the males and 53% of the females believed that they could become HIV infected. Fifty-three percent of the male and 75% of the female respondents had had a previous HIV test. However concern about HIV did not significantly decrease the prevalence of HIV risk behaviors. Peer outreach and on-the-street counseling and testing is a successful method of increasing HIV testing among high risk youth. Youth are concerned about HIV infection but that concern does not translated into a change in risk behaviors.

Quantification and measurement of human lens opacities using the lens opacity meter.

Lens opacity was quantified in 85 cataractous patients, using a new instrument: the lens opacity meter 701 (LOM; Interzeag, Schlieren, Switzerland). Cataracts were classified as nuclear, cortical, subcapsular and mixed forms. Sensitivity, specificity and reproducibility of the results were evaluated by statistical analysis. Visual acuity was correlated with LOM values in patients with nuclear and mixed cataracts. Moreover, the instrument gave a good degree of reproducibility only in patients who presented these forms of lens opacities. Our findings demonstrate that the LOM 701 is able to detect and to measure only lens opacities which affect the central area of the lens.

[Oroantral communications. The gold foil method].

The Authors propose the method of the golden leave to close oro-antral communications. The main advantages offered by this technique are the following: 1) marked reduction of the previously observed loss of vertical height of the alveolar bone (7-8% of the original values); 2) the post-operative phase is, most of the time, uneventful.

Bendazac and benzydamine for treatment of cataract: individualized therapy by the "BLOA test".

It was found that two chemically very close Non-Steroid Antiinflammatory Drugs (NSAID), bendazac and benzydamine, were able to reduce the Biological Liquid Oxidant Activity (BLOA) in vitro (bendezac) and in vivo (bendazac and benzydamine). Four hundred and seven patients were treated with bendazac and 599 with benzydamine. After a single dose oral administration they effected a BLOA Reducing Activity (BRA) ranging from 5% to over 20% in about 40% of cataractous patients. When these drugs were able to reduce the BLOA, they showed anticataract activity in about 50% and about 90% of patients according to the extent of BRA, i.e., less than 20% and greater than or equal to 20% of the basal value. This fact suggests that the anticataract agent is not the original NSAID (prodrug) but a NSAID metabolite or an elicited endogenous compound which produced the BLOA reduction. Individual BLOA could be reduced in vivo by benzydamine or bendazac, by both or by neither of them. This finding may be accounted for by selective biotransformation of each patient's original NSAID into the antioxidant anticataract compound. However, other possible mechanisms of the anticataract activity beside antioxidant activity might take place, such as protein and membrane stabilization, together with a not yet defined activation of enzymes within the lens effecting the reversal of cataractous opacity. Several side effects were apparent in short and long term treatments. The final conclusion of our study is that bendazac at a dosage ten-fold lower than that used in the clinics is anticataract drug when orally administered to "BLOA test selected" patients, at least for short term treatment of young, otherwise healthy humans with cortical cataract.
