PURPOSE: Birt-Hogg-Dubé Syndrome (BHDS) is a rare autosomal dominant condition that can predispose patients to numerous cutaneous fibrofolliculomas and other cutaneous lesions, pulmonary cysts with spontaneous pneumothorax, and multifocal renal tumors and cancer. The genetic mutations responsible for BHDS are related to tumor suppression and the mammalian target of rapamycin (mTOR) pathway. Previous reports of the ocular findings in BHDS include eyelid fibrofolliculomas, "flecked chorioretinopathy," and one report of choroidal melanoma...

With the growing number of fluoroscopic guided endoscopic procedures, radiation-related risk needs to be further assessed. Recent evidence indicates that radiation cataractogenesis occurs at a lower dose threshold than previously believed. While body aprons and thyroid shields are well-established standard protection during fluoroscopy, ocular safety and the use of protective eyewear are not as well defined. This prospective study answered two important questions: Does the standard body dosimeter provide an accurate ocular dosimetry? And what is the time of fluoroscopy needed to warrant using lens protection? It also raises the question whether current guidelines need to be updated...

Conjunctival tumors encompass a broad range of diagnoses. The 3 most important malignant tumors include ocular surface squamous neoplasia (OSSN) (14%), melanoma (12%), and lymphoma (7%). Conjunctival malignancies are rarely found in children. Regarding OSSN, pre-disposing conditions include chronic solar radiation, immune deficiency (HIV), organ transplant, autoimmune conditions, xeroderma pigmentosum, and chronic exposure to cigarette smoke. OSSN is managed surgically or with topical/injection immunotherapy or chemotherapy...

REVIEW

Endovascular procedures expose both patients and physicians to fluoroscopic ionizing radiation that carries a dose-dependent risk of acute toxicity and a small, but demonstrable, long-term risk of malignancy due to resultant genetic mutations. Exposure doses vary widely based upon patient-related factors including body size and anatomic complexity, operator technique, procedure type (diagnostic vs. therapeutic), vascular bed imaged, and imaging equipment employed. Effective dosage may vary as much as 200-fold for physicians and 20-fold for patients depending upon the procedure: for example, complex aortic interventions with branched graft devices may convey mean effective doses of more than 0...

PURPOSE: Neonates are particularly challenging to treat. A novel patented drug delivery device containing a rapidly disintegrating tablet held within a modified nipple shield (NSDS) was designed to deliver medication to infants during breastfeeding. However concerns exist around dermatological nipple tolerability with no pharmaceutical safety assessment guidance to study local tissue tolerance of the nipple and the areola. This is the first Slug Mucosal Irritation (SMI) study to evaluate irritancy potential of GRAS excipients commonly used to manufacture rapidly disintegrating immediate release solid oral dosage form METHODS: Zinc sulphate selected as the antidiarrheal model drug that reduces infant mortality, was blended with functional excipients at traditional levels [microcrystalline cellulose, sodium starch glycolate, croscarmellose sodium, magnesium stearate]...
