Benefits of seat belt reminder systems.

This study sought to determine whether fitting a more aggressive seat belt reminder system to new vehicles would be cost-beneficial for Australia. While seat belt wearing rates have been observed around 95% in the front seat, non-wearing rates in casualty crashes are as high as 33% among persons killed and 19% among seriously injured occupants. Benefits were computed for three device options (simple, simple-2 and complex) and three introduction scenarios (driver-only, front seat occupants and all occupants).

Lower limb injuries to passenger car occupants.

A detailed examination was undertaken of hospitalized car occupants who sustained a lower limb injury in a frontal crash. The assessment included an analysis of the type, severity and causes of these injuries and mechanisms involved in lower limb fractures. The findings showed that fractures and dislocations occurred in 88% of lower limb injury cases, that more than half were from crashes < 48 km hour-1 and that the number of fractures was directly proportional with delta V.

[Heterotopic cloacogenic carcinoma of the lower lip].

Cloacogenic carcinoma is a tumour which develops from cylindric epithelial cells at the anorectal junction. Besides this usual localization, other sites have been described including the vagina, urethra, sigmoid colon, vulva and perianal skin. We observed a labial localization in a 50-year-old woman.

Neurotrophic trigeminal syndrome after pontine stroke.

The present study describes a patient, aged 72 yrs, with pontine crossed syndrome, displaying ipsilateral to the lesion a syndrome of cranial nerves V, VI, VII, VIII, on the right; a right neocerebellar syndrome; anhidrosis in the right hemibody; contralateral to the lesion: thermoalgic anesthesia with hyperhidrosis in the left hemibody. Concomitant with the pontine lesion, the patient developed torpid trophic ulcerations all over the right hemiface which, in the course of one year, became deformed, retractile, depigmented of hyperpigmented scars, the erosion being so deep at the level of the right nasal wing that the latter disappeared. This clinical picture developed in a patient with basilar invagination of 3 mm and left humeral micromelia.
