[Research and formal demonstration of evidence of efficiency in occupational medicine].

There is an increasing pressure on occupational health professionals to ensure that their practice is based on a quality standard and an evidence of appropriateness. The efficacy-effectiveness of their activity strictly depends on their intellectual and professional integrity, their technical and legal competence, but also on the quality of the relations with the company organisation they are able to establish. We asked to some occupational physician when they considered their interventions in the workplace to be efficacious. Then, accordingto our epexrience, we propose some effectiveness indicators, particular concerning health surveillance and health educttaon, that should be evaluated to verify the health professional agccvity agreement to quality standards.

[Efficacy in occupational medicine: proposals of the regional sections of SIMLII of Lombardy and Emilia Romagna].

The efficacy in Occupational Medicine is based on the degree of attainment of workers health and safety care. The Occupational Physician activity, attending on business parts, gives a contribution to the mission of the firm leading to the workers health/safety. The Occupational Physician actions are conditioned by workers features and by the other members of prevention system. It is necessary to verify the efficacy, the efficiency and the adequacy of the Occupational Physician activity finding goals and specific indicators.

[Validity of some urinary tests considered singly or in combination in the study of renal effects of cadmium].

A number of indicators of renal effect (N-acetyl-glucosaminidase, retinol binding protein, beta-2-microglobulin, albuminuria) were measured in 42 cadmium-exposed workers divided into 3 subgroups on the basis of the results of the last 10 years' biological monitoring (less than 3, 3-10, greater than 10 micrograms/l). An increase in the first three indicators was observed, particularly in the third subgroup, which, however, due to the wide dispersion of the values, was not statistically significant by the Kruskal-Wallis test. Taking the indicators singly, the marked increase in RBP and beta-2-microglobulin in the heavily exposed subjects was confirmed, along with an increasing sensitivity for NAG, while albuminuria levels were unchanged. Assessment of the "degree of association" of the altered tests demonstrated that the number and type of "association" varies between the subgroups in relation to the exposure conditions: in the first group there were no associations between the altered tests, whereas there were 2 duplicates in the second and 2 duplicates, 2 triplicates and 3 quadruplicates in the heavily exposed group. In the study of the renal effects of cadmium, it is therefore advisable to use several indicators and assess their behaviour both singly and combined, and also analyse the altered tests on the basis of the number and type of "association".

Sensory-motor conduction time in amyotrophic lateral sclerosis.

19 ALS patients were submitted to motor evoked potentials (MEP) and F-wave from thenar muscles. Somatosensory evoked potentials (SEP) from median nerve were recorded as well in 16 patients. MEP were bilaterally absent in 4 patients (21%) and monolaterally absent in 6 patients (3.6%). Among patients with recordable waves, MEP and F-wave were significantly delayed. Their upper motor neuron conduction time was clearly abnormal only in one case. In SEP recordings the N9-N13 was significantly delayed, but the N13-N20 was normal. Four patients showed a combined sensory-motor dysfunction (increase of both N19-N13 interval and F-wave latency).

Auditory and somatosensory evoked potentials in brain-dead patients.

The short latency evoked potentials, allowing to assess the brain stem's function, can supply useful information in the diagnosis of Brain Death (BD). 15 BD patients were submitted to the auditory brain stem response (ABR); in 7 cases somatosensory evoked potentials from the medial nerve (SEP) were also recorded. The ABR was absent in 11 cases (73.3%), while in 3 cases only the I wave was present (20%); in one case the low-voltage I-V waves were present. Regarding the SEP, in 3 cases (42.9%) only the N9-N13 and P9-P13 waves were present, while in another 3 cases (42.9%) a N13/P13 dissociation was observable. In the remaining case, which presented a still reproducible I-V interval, the SEP was normal, thus excluding the diagnosis of BD. The ABR and the SEP, which are not roughly influenced by general anaesthetics and sedatives, are thus helpful in diagnosing BD. The SEP seems able to supply useful information more frequently than the ABR, but their combined use can guarantee maximum security of excluding false positives.

Neurobehavioral functions in operating theatre personnel exposed to anesthetic gases.

Neurobehavioral functions in paramedical operating theatre personnel were assessed in a cross-sectional survey. Sixty-two subjects (40 males and 22 females) occupationally exposed to anesthetic gases were examined and compared to 46 unexposed hospital workers (18 males and 28 females). The Simple Reaction Time (SRT) test was selected from the MANS battery (Milan Automated Neurobehavioural System). In order to evaluate acute and subacute types of effects on performance, the test was administered before and after the work shift, at the beginning and at the end of the working week. In addition, the complete battery was administered during one working day without exposure to anesthetic gases. On the last day of the working week, atmospheric nitrous oxide (N2Oa) ranged from 7 to 553 ppm (geometric mean 62.6), atmospheric ethrane (ETHa) ranged from 0.1 to 18.8 ppm (geometric mean 1.3), and urinary N2O (N2Ou) ranged from 4 to 297 micrograms/l (geometric mean 26.8). An impairment of performance on the SRT test was observed at the end of the working week in subjects exposed to anesthetic gases compared to controls. This alteration was observed also considering only the subjects exposed to less than 55 micrograms/l (which is the Italian exposure limit for N2Ou, equivalent to 100 ppm for N2Oa). No significant differences were observed for the other psychometric tests. No dose-effect relationships where found between SRT test score and the indicators of exposure (N2Oa, ETHa, N2Ou).(ABSTRACT TRUNCATED AT 250 WORDS)

Neurobehavioral functions in operating theatre personnel: a multicenter study.

The study was conducted to evaluate neuropsychological symptoms, subjective stress and response speed functions in subjects occupationally exposed to low levels of anesthetic gases. A group of 112 operating theatre personnel exposed to anesthetic gases (nitrous oxide and isoflurane), and 135 non exposed hospital workers from 10 hospitals in Northern Italy were examined before and after the shift on the first and the last day of the working week. Three different tasks were administered: a complex reaction time test (the Stroop Color Word); a questionnaire for neuropsychological symptoms (EURO-QUEST); the block design subtest (WAIS). Biological and atmospheric indicators of exposure were measured. In the exposed group, the geometric mean of urinary nitrous oxide at the end of the shift was 7.1 micrograms/l (95th percentile 12.4, range 1.5-43) on the first and 7.8 micrograms/l (95th percentile 21.5, range 1.0-73.3) on the last day of the working week. On the same days, end of shift urinary isoflurane was 0.7 microgram/l (95th percentile 2.6, range 0-4.7) on the first day and 0.8 microgram/l (95th percentile 2.0, range 0-5.6) on the last. The exposed and control subjects were comparable for both basic intellectual abilities and subjective stress levels. No statistical differences were observed between exposed and control subjects for neuropsychological tests and symptoms. No dose-effect relationships were observed between the exposure indicators and the test results. In conclusion, no early behavioral effect on the central nervous system was detectable at the exposure levels measured. The biological exposure limits of 13 micrograms/l for nitrous oxide and 1.8 micrograms/l for isoflurane corresponding respectively to the atmospheric concentrations of 25 ppm and 0.5 ppm seem to be adequately protective for the integrity of workers' neurobehavioral functions, as measured with the tests used.
