Orally administrated nonsteroidal anti-inflammatory drugs are effective in the treatment of a variety of acute and chronic pain conditions but their use may be associated with serious systemic adverse effects which are correlated with the therapeutic plasma levels of the drug. In order to minimize the incidence of drug related systemic events, topical formulations of the nonsteroidal anti-inflammatory drugs have been developed. A recently performed review of the evidence from randomized, double-blind, placebo controlled trials with topically applied NSAIDs in the treatment of acute pain confirmed the previously described pain relief effectiveness. For all topical nonsteroidal anti-inflammatory drugs combined, in comparison to placebo, the number needed to treat (NNT) to achieve a clinically meaningful pain relief of 50 % was 4.5 (3.9 to 5.3) for treatment periods of 6 to 14 days. Local skin reactions were generally mild and transient, and did not differ from placebo. ⋯ The results of the current post-authorization study confirm beneficial pain intensity reducing efficacy of Ketospray 10% associated with good local tolerability of 7 days treatment course. Concomitant administration of systemic pain relieving medication did not substantially contribute neither to the relief of pain at rest nor of pain on movement among the subjects of respective study populations.

X-linked Retinoschisis is a bilateral retinal disease with a recessive X-linked inheritance, characterized by a macular involvement. Maculopathy consists of bilateral star-shaped microcystic changes. Peripheral retina is sometimes involved with schisis. ⋯ OCT images showed a separation of neurosensorial retina that coincided with classical histopathological findings. Examination results were correlated with clinical examination and compared with ERG findings. OCT images underline an increase of retinal thickness with a separation in the nerve fiber layer in the foveal space.

Retrospective analysis of data obtained from 161 patients with ocular hypertension who performed the CET in 1980, and were subsequently followed to see whether they developed OAG. CET was performed always in the morning Eyelids were closed by bandaging for 1 h in a quiet environment, with the patient seated and not sleeping. IOP was measured again 8 to 10s after opening the eyelids. ⋯ Eyelid closure for 60 minutes results in a net elevation of IOP the extent of which depends on the balance between the increase of aqueous humour secretion and its outflow. Therefore, the CET may discriminate individuals with a normal outflow from individuals with a less functional outflow, which are evidently those at a higher risk of developing glaucoma.

A 16-years-old boy has developed subepithelial infiltrates and an epidemic keratoconjunctivitis from adenovirus in both eyes. Clinical case was analyzed by confocal microscopy (40x mode, Nidek ConfoScan 4) before and after administration of topical cyclosporine. ⋯ The confocal microscopy performed on the surface of the stroma before and after treatment with cyclosporine suggests the presence of a localized immune activation in subepithelial layer.

Guanosine has been reported to exert neuroprotective effects. We recently reported that, following intraperitoneal (i.p.) injection to rats, it resulted to be widely distributed. Its metabolic product guanine also rapidly increased in all the tissues, including brain, after i.p. injection of guanosine and consistently we found a significant enzymatic activity of a soluble purine nucleoside phosphorylase in the plasma of the treated animals. ⋯ Moreover the nucleobase was able to rescue the memory trace also when administered after training. Neither guanosine nor guanine had effects on locomotor activity. These results indicate that guanine can exert important biological activities which may be different from those mediated by its precursor guanosine, thus this evenience should be taken into account when the biological effects of guanosine are evaluated.
