The use of macro-radiography in the initial examination of the petrous temporal region.

The results of the survey show that macroradiography of the petrous temporal region is not a common practice. However, the results of the tests show that an increase in discernible detail can be achieved with only a slight increase in geometrical unsharpness, no loss in resolution and, if departmental protocol is to produce AP images through the magnified orbits, a reduction of over 100 times in the radiation exposure dose to the lens of the eye by producing PA macroradiographs instead. Taking into consideration both the image quality of the macro-radiographs obtained, and the radiation exposure dose received by the lens of the eye, the most suitable macroradiographic technique has been implemented within the department as a routine procedure.

Rothmund-Thomson syndrome. A case report, phototesting, and literature review.

Rothmund-Thomson syndrome is a rare hereditary syndrome with developmental defects. Characteristics of this syndrome, based on a review of 107 reported cases in the literature, are (in descending order) as follows: early onset of poikiloderma, short stature, absence or sparseness of eyebrow and/or eyelash hair, familial juvenile cataracts, small hands and bone defects, sunlight sensitivity, hypogonadism, defective dentition, nail abnormality, hyperkeratosis, and mental retardation. Recently we encountered a 25-year-old white woman who had developed this syndrome but without juvenile cataracts, hypogonadism, or mental retardation. She had developed a basal cell epithelioma, which has not previously been described in this syndrome. Phototesting with monochromatic radiation and with a solar simulator showed photosensitivity in the ultraviolet A range but not in the ultraviolet B range. This case may represent an example of the Thomson type. The case is described and the literature reviewed.
