Atopic dermatitis, conjunctivitis, and hand dermatitis among Swedish dental personnel, including use of personal protective devices.

A previous study on dental personnel in northern Sweden show that dentists had a significantly higher prevalence of self-reported and physician-diagnosed atopic dermatitis and conjunctivitis, compared to chair assistants and referents (Lönnroth & Shahnavaz 1998). Further, significantly more male dentists reported experience of hand dermatitis compared to male referents. To compare the prevalence among dental personnel working in other geographical areas of Sweden, and survey the use of personal protective equipment, a questionnaire study was conducted during 1997, which included all dentists and his/her chair assistants, working in general private and public dental care in Sweden. A total of 7384 dental personnel were included in the study, 4293 dentists (54.7% male and 45.3% female), and 3090 chair assistants. Logistic regression was used for analysing data. Results show that significantly more dentists reported symptoms of atopic dermatitis, conjunctivitis, and hand dermatitis, and had been diagnosed by a physician, compared to chair assistants. However, they did not report more sick-leave due to symptoms, compared to chair assistants. More female used protective devices, than male, and more chair assistants than dentists. Significantly more dental personnel in public dental care used protective devices, than in private dental care. Use of gloves, and face mask, decreased with increasing age but, use of eye protection, mainly in form of prescription spectacles, increased. The prevalence of hand dermatitis decreased significantly with increasing age but, more for female (p < 0.0001), than for male (p = 0.01).

Association between health information, use of protective devices and occurrence of acute health problems in the Prestige oil spill clean-up in Asturias and Cantabria (Spain): a cross-sectional study.

BACKGROUND: This paper examines the association between use of protective devices, frequency of acute health problems and health-protection information received by participants engaged in the Prestige oil spill clean-up in Asturias and Cantabria, Spain. METHODS: We studied 133 seamen, 135 bird cleaners, 266 volunteers and 265 paid workers selected by random sampling, stratified by type of worker and number of working days. Information was collected by telephone interview conducted in June 2003. The association of interest was summarized, using odds ratios (OR) obtained from logistic regression. RESULTS: Health-protection briefing was associated with use of protective devices and clothing. Uninformed subjects registered a significant excess risk of itchy eyes (OR:2.89; 95%CI:1.21-6.90), nausea/vomiting/dizziness (OR:2.25; 95%CI:1.17-4.32) and throat and respiratory problems (OR:2.30; 95%CI:1.15-4.61). There was a noteworthy significant excess risk of headaches (OR:3.86: 95%CI:1.74-8.54) and respiratory problems (OR:2.43; 95%CI:1.02-5.79) among uninformed paid workers. Seamen, the group most exposed to the fuel-oil, were the worst informed and registered the highest frequency of toxicological problems. CONCLUSION: Proper health-protection briefing was associated with greater use of protective devices and lower frequency of health problems. Among seamen, however, the results indicate poorer dissemination of information and the need of specific guidelines for removing fuel-oil at sea.

[Pars plana implantation of a ganciclovir drug carrier in patients with cytomegalovirus retinitis and AIDS. Indications, follow-up and postoperative complications].

UNLABELLED: We performed an open clinical trial to assess the safety and efficacy of a 1 microgram/h ganciclovir implant for the treatment of newly and pretreated cytomegalovirus (CMV) retinitis in patients with the acquired immunodeficiency syndrome (AIDS). PATIENTS AND METHODS: Thirty-two eyes (20 patients) received the ganciclovir intraocular device and were prospectively followed up from 30 to 365 days. We used a modified technique for fixation of the device in half of the patients. The modification improved the fixation of the implant with a two-hole technique in the strut. RESULTS: Thirty eyes showed stabilization of the retinitis over the time, but in two patients resistance against ganciclovir and other nucleoside analogue compounds developed. Postoperative complications included vitreous hemorrhage (n = 1), cataract (n = 1), and uveitis anterior (n = 1). Late retinal detachment was seen in five eyes (25%) at 30 to 60 days after implantation. Followup until 1 year after implantation did not show progression of CMV retinitis in 18 to 20 patients. All received antiviral CMV therapy to protect noninfected eyes and intestinum against CMV infection. CONCLUSIONS: The ganciclovir intraocular device seemed to be effective in most cases of CMV retinitis and offers a promising alternative for cytomegalovirus retinitis. Patients pretreated longer than 6 months with i.v. ganciclovir have to be carefully selected for implantation, because resistance against ganciclovir could be three times more likely than in i.v.-therapy naive patients.

Ocular blunt trauma: loss of sight from an ice hockey injury.

A case of ocular blunt trauma is described in which a 17 year old male ice hockey player collided with an opponent during a game. The opponent's stick travelled under the patient's half face visor and struck his left eye causing hyphema, angle recession, lens subluxation, and choroidal rupture over the macula, permanently reducing his vision to counting fingers. Sequelae of ocular blunt trauma are discussed along with methods of injury prevention by addressing players' behaviour and safety equipment. This injury is unlikely to have occurred with properly used full face protection.

Early components of the human vestibulo-ocular response to head rotation: latency and gain.

To characterize vestibulo-ocular reflex (VOR) properties in the time window in which contributions by other systems are minimal, eye movements during the first 50-100 ms after the start of transient angular head accelerations ( approximately 1000 degrees /s(2)) imposed by a torque helmet were analyzed in normal human subjects. Orientations of the head and both eyes were recorded with magnetic search coils (resolution, approximately 1 min arc; 1000 samples/s). Typically, the first response to a head perturbation was an anti-compensatory eye movement with zero latency, peak-velocity of several degrees per second, and peak excursion of several tenths of a degree. This was interpreted as a passive mechanical response to linear acceleration of the orbital tissues caused by eccentric rotation of the eye. The response was modeled as a damped oscillation (approximately 13 Hz) of the orbital contents, approaching a constant eye deviation for a sustained linear acceleration. The subsequent compensatory eye movements showed (like the head movements) a linear increase in velocity, which allowed estimates of latency and gain with linear regressions. After appropriate accounting for the preceding passive eye movements, average VOR latency (for pooled eyes, directions, and subjects) was calculated as 8.6 ms. Paired comparisons between the two eyes revealed that the latency for the eye contralateral to the direction of head rotation was, on average, 1.3 ms shorter than for the ipsilateral eye. This highly significant average inter-ocular difference was attributed to the additional internuclear abducens neuron in the pathway to the ipsilateral eye. Average acceleration gain (ratio between slopes of eye and head velocities) over the first 40-50 ms was approximately 1.1. Instantaneous velocity gain, calculated as Veye(t)/Vhead(t-latency), showed a gradual build-up converging toward unity (often after a slight overshoot). Instantaneous acceleration gain also converged toward unity but showed a much steeper build-up and larger oscillations. This behavior of acceleration and velocity gain could be accounted for by modeling the eye movements as the sum of the passive response to the linear acceleration and the active rotational VOR. Due to the latency and the anticompensatory component, gaze stabilization was never complete. The influence of visual targets was limited. The initial VOR was identical with a distant target (continuously visible or interrupted) and in complete darkness. A near visual target caused VOR gain to rise to a higher level, but the time after which the difference between far and near targets emerged varied between individuals.
