A randomized prospective double-blind study was performed to compare the efficacy of a single 5 min 1072 nm narrow waveband light application against topical aciclovir applied five times daily in the treatment of herpes labialis. Treatment was initiated within 36 h of the onset of symptoms and the end point was defined as the day that the crust was discarded leaving an uninterrupted underlying skin at the site of the cold sore. The results demonstrated that a single 5 min light treatment significantly reduced cold sore healing time by 4 days; 1072 nm light healed cold sores in 4.3 +/- 1.8 days (mean +/- SD) as compared with aciclovir applied five times daily, 8.5 +/- 3.0 days (P < 0.0001).

Injuries to the spinal cord may be associated with increased healing of fractures. This can be of benefit, but excessive bone growth can also cause considerable adverse effects. We evaluated two groups of patients with fractures of the spinal column, those with neurological compromise (n=10) and those without (n=15), and also a control group with an isolated fracture of a long bone (n=12). The level of transforming growth factor-beta (TGF-beta), was measured at five time points after injury (days 1, 5, 10, 42 and 84). The peak level of 142.79 ng/ml was found at day 84 in the neurology group (p<0.001 vs other time points). The other groups peaked at day 42 and had a decrease at day 84 after injury (p

SUMMARY. Total. ultrafiltrable and ionised calcium concentrations were determined in anaerobic serum from healthy volunteers. patients immediately before and after haemodialysis and patients on continuous ambulatory peritoneal dialysis (CAPO). Protein-bound. complexed and albumin-corrected total calcium concentrations were calculated from the results. During haernodialysis, complexed calcium did not change, whereas the other fractions increased. For patients on CAPO, the total, ionised and protein-bound calcium results were frequently lower than the reference group, whereas the ultrafiltrable and albumin-corrected total calcium results were within or higher than the reference group. Albumin-corrected total calcium for all subjects correlated better with ultrafiltrable calcium than with ionised calcium. It was concluded that low ionised calcium concentrations found in CAPO patients may be related to low albumin concentrations, and the concentration of physiologically active calcium may be normal in these patients.
