    Notes: Summary Thirty-six patients fulfilling the criteria for Reiter's disease were studied (29 men and 7 women; 4:1). The mean age of onset was 23.8 years; in 75% of patients the onet was in the second and third decades. Clinical manifestations included low back pain and stiffness (69%), non specific urethritis (53%), heel pain (44%), radiographic sacroiliitis (42%), conjunctivitis (39%), dysentery and diarrhoea (33%), mucosal ulcerations (17%) kidney disease (14%), anterior uveitis (19%), and keratoderma blennorrhagicum (8%). Peripheral arthritis was mono or oligoarthritis in 58% of patients, mainly affecting the large joints of lower extremities, and it was often asymmetric (mean degree of asymmetry=0.37). HLA-B27 antigen was detected in 83% of 36 patients compared with 5.9% of 118 controls (relative risk 79, corrected Fisher's P=7.719E-18).

    Notes: Abstract In seven recently diagnosed and untreated patients with tobacco amblyopia the light and dark adapted electroretinograms were recorded together with visual acuity, central fields and the Farnsworth-Munsell 100-Hue test. After 3 months treatment with injections of hydroxocobalamin all these tests were repeated. An improvement in visual acuity resulted in all cases. A significant reduction in the Farnsworth-Munsell total error score of the seven patients was noted (p 〈 0.01). A significant increase in the amplitude of the light adapted b-wave of the ERG was found (0.01 〈 p 〈 0.02) following the course of hydroxocobalamin injections. No other significant changes in the ERG were demonstrated. It is suggested that the ERG changes demonstrated an improvement in an abnormal biochemical state in those bipolar and perhaps Müller cells of the inner nuclear layer of the retina which make electrophysiological connections chiefly with foveal cones.

    Notes: Abstract A cooling fin attached to a cylinder of circular cross section is considered. We obtain sharp upper and lower estimates for the maximum heat dissipation under the constraint that the total weight of the fin should not exceed a given bound. It is assumed that the boundary of the cylinder has a constant temperature and that Newton's law of cooling holds.
