analysis of endocanalicular light pipe transillumination in endoscopic dacryocystorhinostomy: Anatomic considerations and cautions for the transitioning.

Orbit 2021 Jun 3:1-5. Epub 2021 Jun 3.

Department of Ophthalmology, Harvard Medical School, Boston, Massachusetts, USA.

: Localization of the lacrimal sac is a critical step during endoscopic dacryocystorhinostomy (endo-DCR). A "light pipe" can be used to transilluminate the lacrimal sac endonasally. We hypothesized that this may misguide the surgeon learning endo-DCR to create an osteotomy mostly posterior to the maxillary line if only the bone overlying the transillumination was to be removed, as the thinner lacrimal bone will transmit light more readily than the thicker maxillary bone of the frontal process of the maxilla that forms the anterior lacrimal sac fossa.

Outcomes of Conventional External Dacryocystorhinostomy with and without Mitomycin C: Experience from Eastern Nepal.

Nepal J Ophthalmol 2020 Jul;12(24):209-215

Bharatpur Eye Hospital, Bharatpur, Chitwan, Nepal.

Introduction: Dacryocystorhinostomy (DCR) is the commonest surgery for nasolacrimal duct obstruction. Inhibition of the scarring process within the anastomosis and rhinostomy site which has been attributed to the failure of this procedure, might improve the success rate of DCR. The objective of this study was to evaluate the outcomes of DCR with Mitomycin-C (MMC) and to compare the results of DCR with and without MMC. Read More

NIS in non-thyroidal tissues and impact on thyroid cancer therapy.

Endocr Relat Cancer 2021 May 1. Epub 2021 May 1.

J Sipos, Endocrinology, The Ohio State University, Columbus, 43210, United States.

Radioiodine (131I) has been used to ablate thyroid tissue not removed by surgery or to treat differentiated thyroid cancer that has metastasized to other parts of the body for the past 80 years. However, the Na+/I- symporter (NIS), which mediates active iodide uptake into thyroid follicular cells, is also expressed in several non-thyroidal tissues. This NIS expression permits 131I accumulation and radiation damage in these non-target tissues, which accounts for the adverse effects of radioiodine therapy. Read More

Novel Findings in Floating-Harbor Syndrome and a Mini-Review of the Literature.

Mol Syndromol 2021 Mar 30;12(1):52-56. Epub 2020 Nov 30.

Department of Medical Genetics, Faculty of Medicine, Ataturk University, Erzurum, Turkey.

Floating-Harbor syndrome (FHS) is a rare autosomal dominant genetic disorder characterized by proportionate short stature with delayed bone maturation, lack of expressive language, and distinctive facial features including a large nose, long eyelashes, deeply set eyes, and triangular face. Mutations in the gene cause truncated SNF2-related CREBBP activator protein (SRCAP) and lead to FHS. SRCAP is one of several proteins that act as coactivator for the CREB-binding protein which is associated with Rubinstein-Taybi syndrome (RSTS). Read More
