Is there a clinical usefulness for radiolabeled somatostatin analogues beyond the consolidated role in NETs?

Indian J Radiol Imaging 2017 Oct-Dec;27(4):509-516

Nuclear Medicine Unit, Department of Clinical and Experimental Medicine, F. Magrassi, A. Lanzara, Seconda Università di Napoli, Napoli, Italy.

The somatostatin (SS) receptor scintigraphy (SRS), using octreotide radiolabelled with In (Ocreoscan©, OCT), is a consolidated diagnostic procedure in patients with neuroendocrine tumors (NET) because of an increased expression of somatostatin receptors (SS-R) on neoplastic cells. Uptake of SS analogues (SSA) can also be due to SS-R expression on nonmalignant cells when activated as lymphocytes, macrophages, fibroblasts, vascular cells. Because of this uptake, clinical indications can be found either in neoplasms not overexpressing SS-R, as nonsmall cell lung cancer, and in active benign diseases. Read More

The pathogenesis of Graves' orbitopathy (GO) is not completely understood. Coexistent hyperfunction of the thyroid gland is frequent; however, GO may also coexist with hypo- or euthyrodism. The course of GO is largely independent of thyroid function, although elevated serum TSH is known to negatively interfere with GO course. Read More

Modified lateral orbital wall decompression in Graves' orbitopathy using computer-assisted planning.

Int J Oral Maxillofac Surg 2018 Feb 31;47(2):167-174. Epub 2017 Oct 31.

Department of Oral and Maxillofacial Surgery, Hannover Medical School, Hannover, Germany.

Graves' orbitopathy, a condition seen in the autoimmune syndrome Graves' disease, affects the fatty tissue and muscles inside the orbit. Graves' orbitopathy is associated with increasing exophthalmos and sometimes leads to compressive dysthyroid optic neuropathy, resulting in progressive vision loss. Dysthyroid compressive optic neuropathy, functional problems, and cosmetic problems are the main indications for surgical decompression of the orbit, especially if conservative treatment has not led to a reduction in symptoms.

Fat-removal orbital decompression for thyroid associated orbitopathy: The right procedure for the right patient.

Saudi J Ophthalmol 2017 Jul-Sep;31(3):156-161. Epub 2017 Jun 14.

Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Saudi Arabia.

Orbital decompression is an effective and invaluable procedure for addressing some of the chronic manifestations of Graves' Ophthalmopathy (GO) such as exophthalmos and orbital congestion. Fat-removal orbital decompression (FROD) started to gain popularity after its introduction in the late 20th century. Among the therapeutic armamentarium of techniques and approaches available for orbital decompression, FROD has proven its efficacy and safety in addition to its ability to reduce proptosis in a relatively predictable manner.

A case of concurrent silent sinus syndrome, thyroid eye disease, idiopathic orbital inflammatory syndrome, and dacryoadenitis.

Orbit 2017 Dec 16;36(6):462-464. Epub 2017 Aug 16.

c Oculoplastic and Orbital Surgery Service , Wills Eye Hospital , Philadelphia , Pennsylvania , USA.

This is a retrospective case description of a single female patient found to have concomitant bilateral silent sinus syndrome, bilateral thyroid eye disease, unilateral dacryoadenitis, and idiopathic orbital inflammation that presented as progressive unilateral right-sided proptosis. The spectrum of inflammatory orbital diseases can make discerning between different entities challenging, but more unique in this case was the simultaneous presentation with bilateral silent sinus syndrome, a rare entity in its own right. Identifying each of these concurrent disease processes is important to establishing a multidisciplinary treatment approach to address all the patient's orbital and peri-orbital pathology. Read More
