Decrease of intraocular pressure after fat-removal orbital decompression in Graves disease.

Abstract

PURPOSE: To address the efficacy of fat-removal orbital decompression to reduce intraocular pressure in patients with Graves disease. METHODS: This cohort study included 64 eyes of 39 patients with Graves disease. Thirteen men and 36 women, with a mean age of 52.5 years (range, 27 to 80 years), underwent fat-removal orbital decompression. Intraocular pressure (applanation) and proptosis (Hertel exophthalmometry) were prospectively investigated before surgery and 1 week and 6 months after surgery. RESULTS: The volume of resected fat was 6.4+/- 4.5 (3 to 12) ml. The intraocular pressure in primary position decreased from 19.3+/- 4.4 mm Hg to 17.0+/- 2.9 mm Hg at 1 week (p<0.001) and 15.9+/- 3.7 mm Hg at 6 months (p<0.001). Mean proptosis dropped from 24.3+/- 2.5 mm before surgery to 19.9+/-3.0 mm at 1 week (p<0.01), and 19.9+/-3.1 mm at 6 months (p<0.01). Intraocular pressure decrease neither correlated to the volume of resected fat nor to proptosis reduction. CONCLUSIONS: Fat removal reduces intraocular pressure in patients with Graves disease, with no correlation to the volume of resected fat.

Rapidly decellularized adipose tissue induces soft tissue vascularization in potential anatomical spaces.

Decellularized tissues provide biological cues owing to the wealth of structural and regulatory factors that promote angiogenesis, adipogenesis, and myogenesis and facilitate neurite outgrowth. Here, we demonstrated the advantages of decellularized adipose tissue (adipoECM) over defined collagen-based biomaterials for host tissue integration. Three batches of human adipose tissue were decellularized using a rapid decellularization protocol and analyzed using mass spectrometry. To assess the biological activity of the decellularized materials, adipoECM and a reference standard of care biomaterial (Integra&#xae;DRT, also containing collagen I and glycosaminoglycans) were implanted subcutaneously, but far from the wound bed (in anatomical potential spaces) of immunocompetent BALB/c mice. The mice were euthanized in the acute (1 day) and chronic (day 60) inflammatory reaction phases, followed by biomaterial excision and Masson&#x2019;s trichrome immunohistofluorescence imaging of the paraffin-embedded specimens. Each batch of processed tissue passed a quality control check, showing a low level of donor genomic DNA, lack of nuclei, lipids, endotoxins, and bacterial contamination. Mass spectrometry revealed that all batches of decellularized tissue mainly contained collagen I and, to a lesser degree, collagen III, collagen IV, collagen V, laminin, fibrillin, fibronectin, tenascin, and elastin. No acute inflammatory reaction was observed in either material one day post-transplantation. At 60&#x2009;days post-implantation, different cell types were detected in adipoECM specimens, whereas Integra&#xae;DRT remained acellular. Additional immunohistochemical staining of adipoECM revealed CD31-positive cells in the blood vessels. Mesenchymal (CD90 positive) and myeloid (CD14 positive) cells were also detected. Primary cell types involved in soft tissue healing and remodeling were found in the adipoECM-treated group. The ingrowth of blood vessels and mesenchymal cells confirmed the effective integration of adipoECM with host tissues. Our results demonstrate that decellularized adipose tissue implanted away from the wound bed possesses contextual biological activities that promote efficient integration with host tissues.

Clinical trials in elderly patients.

The increasing size of the elderly population means that both the relative and absolute numbers of prescriptions for elderly patients are increasing. Depending on the age group, between 60% and 80% of elderly people are taking medication, and between 20% and 30% are taking at least three drugs. Prescribing for elderly patients as opposed to younger patients is thus ever more important. This has inevitably meant that the drug development process must increasingly recognise the importance of identifying and developing therapeutic targets relevant to older patients. Clearly, the scientific ethical and regulatory principles that determine conduct of clinical trials in younger individuals apply equally to older people. In addition, the development of drugs to be used in older patients requires an awareness of a number of physiological, pathophysiological and sociological considerations.
