The role of vehicle safety glass in eye injuries.

Despite the introduction of compulsory seat belt legislation, the incidence of eye injuries, and their severity, is greater in Auckland, New Zealand, than in London, Canada. A comparison has been made between Auckland (83 cases) and London (50 cases) in a survey from 1 July 1970, to 31 December 1974. Consideration is given to the fact that New Zealand vehicles are equipped with heat-toughened (tempered) glass, whereas in Canada, vehicles are fitted with laminated windscreens.

Health hazards associated with curing light in the dental clinic.

The assessment of side effects of substances encountered in odontology by patients and the dental team must include the direct and indirect effects of irradiation emitted from polymerisation devices. The eyes of the lamp operators are at risk from acute and cumulative effects, mainly due to back-reflection of the blue light. Furthermore, phototoxic and photoallergic reactions originating from absorbed radiation in endogenous or exogenous substances accumulated in the operators' eyes and skin (hands) as well as the patients' oral mucosa must also be taken into consideration. Preventive measures include reading the manufacturers' operating instructions for curing devices and using radiation-filtering protection goggles.

[Stenting for carotid artery stenosis of 55 cases].

OBJECTIVE: To introduce the procedure of carotid stenting, and to summary experiences of 55 cases. To study the theory and clinical significance of carotid stenting for carotid artery stenosis. METHODS: Fifty-five patients with severe carotid atheromatous stenoses were treated by stent implantation. Fifty-eight stents were implanted. Forty-one of these stents were Wallstent, 14 were Smart stents and 3 were OptiMed stents. Cerebral protection device was furnished for 18 patients. RESULTS: During operation, there were 2 cases of small stroke and 2 cases of major stroke. One patient suffered from left eye area deficit, who had a little signs after 3 months. Another patient had consciousness loss and right-side paralysis and had a recovery in consciousness after salvage. The incidence of nervous system complications was 6.9%. Serious stroke rate was 3.5%. The incidence of circulatory system complications was 10.3%. Those patients who received cerebral protection device did not have nervous complication. CONCLUSION: Carotid stenting is effective for the treatment of carotid artery stenosis. The experienced surgeon can make this procedure safe. The procedure's safety is enhanced by using cerebral protection device.

Radiation exposure benefit of a lead cap in invasive cardiology.

BACKGROUND: Occupational head exposure to radiation in cardiologists may cause radiation induced cataracts and an increased risk of brain cancer. OBJECTIVE: To determine the effectiveness of 0.5 mm lead equivalent caps, not previously used in invasive cardiology, in comparison with a 1.0 mm lead equivalent ceiling mounted lead glass screen. DESIGN: An anthropomorphic Alderson-Rando phantom was used to represent the patient. Scatter entrance skin air kerma to the operator position (S-ESAK-O) was measured during fluoroscopy for all standard angulations and the S-ESAK-O per dose-area product (DAP) calculated, as applied to the phantom. RESULTS: Measured mean (SD) left/right anterior oblique angulation ratios of S-ESAK-O without lead devices were 23.1 (10.1), and varied as a function of tube angulation, body height, and angle of incidence. S-ESAK-O/DAP decreased with incremental operator body height by 10 (3)% per 10 cm. A 1.0 mm lead glass shield reduced mean S-ESAK-O/DAP originating from coronary angiography from 1089 (764) to 54 (29) nSv/Gy x cm2. A 0.5 mm lead cap was effective in lowering measured levels to 1.8 (1.1) nSv/Gy x cm2. Both devices together enabled attenuation to 0.5 (0.1) nSv/Gy x cm2. The most advantageous line of vision for protection of the operator's eyes was > or = 60 degrees rightward. CONCLUSIONS: Use of 0.5 mm lead caps proved highly effective, attenuating S-ESAK-O to 2.7 (2.0) x 10(-3) of baseline, and to 1.2 (1.4) x 10(-3) of baseline where there was an additional 1.0 mm lead glass shield. These results could vary according to the x ray systems used, catheterisation protocols, and correct use of radiation protection devices.

Analysis of hurling and camogie injuries.

In 1984, 4500 people with sport injuries attended the Cork Regional Hospital. Of these, 817 were injured in the national game of hurling and camogie. Hand injuries were the most frequent occurring in approximately one third of injured players (33 per cent) and of these, just half had a closed metacarpal fracture. Facial injuries were the second most frequent category (28 per cent). Almost one third of these were nasal fractures, while forehead and eyebrow lacerations, fractured zygoma, loss of teeth are also common. Sport eye injuries referred to the Eye, Ear and Throat Hospital in Cork during the same period amounted to 107, of which 26 occurred in hurling. It is believed that a properly designed protective head gear would largely eliminate such facial and eye injuries.
