Graves' ophthalmopathy is an autoimmune disease manifested as exophthalmus, lid lag and diplopia. As in the accompanying autoimmune thyroid disease, there is an autoimmune homoral and cellular attack on the orbita, mainly the retro-orbital tissues.

Steroids are the comerstone of therapy. We reviewed the evidence for a similar therapeutic effect of I.V., immunoglobulins (IVIGs) and their better side affect profile as compared to steroids. We also described an impressive therapeutic success with IVIG given to a patient with resistant ophthalmopathy. The clinical picture of Graves' ophthalmopathy is attributed to a pathologic hyper - activation of orbital fibroblasts, deposition of collagen and glycosaminoglycans in the extra-cellular matrix and eventually fibrosis. These are mediated by leucoregulin, IL-1, IFN-gamma, and TGF-beta - all secreted by lymphocytes and mast cells in the retorbital space.

Another mode of cell activation is by binding of autoantibodies (presumably thyroid stimulating Ab's) to an antigenic determinant on the surface of fibroblasts.

I.V. immunoglobulins, known today to be active in a variety of autoimmune processes, exert their effect on autoantibodies, complement, phagocytic cells etc. IVIGs also inhibit orbital lymphocytes and fibroblasts through inhibition of IL-1 or/and TGF-beta.

Choice of Infusion Site - Differences in the References of Nurses, Residents and Patients

Insertion of an intravenous (IV) line is a common and routine procedure in hospitalized patients. The literature recommends not to insert an IV line in a limb fold, but other than that there are no guidelines regarding optimal locations for the IV line. In this study we attempted to elucidate whether there are other possible preferences and guidelines for choosing the location of an IV line. We studied four groups: patients at the time of hospitalization, hospitalized patients, nurses and surgical interns on a surgical ward. We found that 91.8% of the patients request to take part in choosing the location of their IV line. Moreover, we found that most patients have a hand preference for the IV, whereas, the ward staff has little location preference. Despite these findings, we discovered that, in practice, most patients were not asked to participate in the decision making process regarding their IV line location. Analysis of the results showed that there is a need to include the patient's preference in choosing the location for the IV line, whenever possible. If the patient doesn't have a preference, the IV line should be inserted in the non-dominant hand or the hand in the bed which is more accessible to the medical & nursing staff.

Intraventricular hemorrhage in full-term neonates is rare; it may develop without any clinical signs. Its cause is not fully understood although some risk factors have been identified. A higher index of suspicion would ensure earlier diagnosis and treatment, which might reduce the rate of severe complications. We describe 2 cases in full-term neonates.

Second Degree A-V Block in Graves© Disease

Cardiac tachyarrhythmias are common in thyrotoxicosis. We report an uncommon case of a 53-year-old woman with Grave's disease who developed second degree A-V block while euthyroid on propylthiouracil. The most likely mechanism is an autoimmune response causing infiltration of the cardiac conduction pathways.
