Clinical manifestations due to pharmacological interactions in pediatric ophthalmic surgery. Topical drugs and general anaesthesia

Introduction. The authors consider the type and the incidence of the adverse effects due to the interaction between ophthalmic drugs and general anaesthesia in pediatric ophthalmic surgery. Patients and Methods. The experience included 176 general anaesthesia in 100 children aged between 9,2 months and 11,4 years (mean age 4,9 years). Results. In the 100 patients we reported: 4 cases (2.7% general anaesthesias) of sinus tachycardia with heart rhythm varying between 170 and 180 beats per minute (3.6%); 5 cases of sinus bradycardia, varying between 60 and 70 beats per minute (3.3%); 3 cases of bronchospasm (2%); 2 cases of psychomotor agitation/disturbances in pre-convulsive state after anaesthesia (1.3%); 3 cases of arterial hypotension (60-70 mmHg) (2%); 7 cases of skin rush around neck and chest (4.6%); 1 case of prolonged apnoea (0.6%). Conclusions. The clinical manifestations, principally on the cardio-circulatory and nervous system are subjected to critical revision, to foresee the pharmacological interferences and therefore to prepare the necessary measure of medical treatment.

Hepcidin and Ferritin Levels in Fever of Unknown Origin: Is There a New Biomarker?

Background and objectives: Significantly elevated serum ferritin levels are associated with both iron overload and some inflammatory conditions. Hepcidin is a protein that interferes with iron absorption in inflammatory states and acts as an acute-phase reactant. Materials and methods: Here we report the case a 33-year-old patient who presented with high fever, skin lesions and arthralgia lasting for 2 weeks. His ferritin level was 13,800 µg/l and his hepcidin level was 61 ng/dl. Results: The final diagnosis was adult onset Still's disease. The condition evolved satisfactorily with steroid treatment, but after several weeks the patient presented with an unexpected recurrence. Conclusions: Hepcidin is a good inflammatory marker that could be useful in the differential diagnosis of hyperferritinaemia.
