The most common ocular findings were anomalies of retinal fundus and minor changes in the outer region of the eyes. The authors noted better VA and less severity of disease than others, which might be due to a different selection of patients, different pattern of alcohol consumption, or genetic differences.

SUMMARYIn this paper we suggest a distribution-free state space model to be used with the Kalman filter in run-off triangles. It works with original incremental amounts and relates the triangle with a column of observed values, which can be chosen in order to describe better the risk volume in each year. On the traditional application of run-off triangles (the paid claims run-off), this model relates the amount paid j years after the accident year with a column of observed values, that can be the claims paid on the first year, the number of claims, premiums, number of risks, etc. Two advantages of this model are the perfect split between observed values and random variables and the capacity to incorporate the changes in the speed of the company's reality into the model and in its projections.Particular care is taken on the evaluation of the final forecast mean square error as well as on the estimation of the model parameters, specially the error variances. Also, two sets of claims data are analysed. In comparison with other methods, namely, the chain ladder, the analysis of variance, the Hoerl curves and the state space modelling with the chain ladder linear model, the proposed model gave a final reserve with a mean square error within the smallest.

Periorbital cellulitis is a relatively common ocular disease in the pediatric population. Early diagnosis of this disease with a prompt intervention is critical to avoid vision and life-threatening complications. In the last years, medical therapy has been expanding for the treatment of orbital cellulitis, instead of the standard surgical approach. The purpose of this study was to describe the outcome of treatment with intravenous antibiotic of periorbital cellulitis in children. A retrospective review of all children admitted with periorbital cellulitis in our hospital between January 2002 and July 2013 was conducted. Cases were divided in two subgroups, pre-septal and post-septal infection. The demographics, clinical findings, treatment and outcomes were analyzed. In total 110 children were included, 93 with pre-septal and 17 with post-septal cellulitis. The mean age was 3.5 years in children with pre-septal cellulitis and 5.5 years in those with post-septal cellulitis (p = 0.149). For both subgroups the most common predisposing factor was sinusitis. Intravenous antibiotic therapy was successful in all except one patient with an orbital abscess who required surgical intervention. In our study complete recovery was achieve in all (except for one) children with periorbital cellulitis treated with intravenous antibiotics only.
