Deficiency of vitamin B12 and/or folic acid as a cause of pyrexia, though known, is rarely reported in literature. We aimed to report a case in a 51 year old woman, who presented with fever and pancytopenia and was diagnosed to have megaloblastic anemia secondary to vitamin B12 and folate deficiency. The pyrexia subsided following the intramuscular injection of vitamin B12 and oral folic acid a...

OBJECTIVES/HYPOTHESIS To evaluate the clinical outcome of patients with acute vocal fold paralysis treated with bovine collagen via percutaneous injection laryngoplasty under simple topical anesthesia. STUDY DESIGN Retrospective case series. METHODS The charts of 38 consecutive patients with acute unilateral vocal fold paralysis who underwent percutaneous injection laryngoplasty under simpl...

Patients with proliferative diabetic retinopathy (PDR) who are refractory to complete panretinal photocoagulation (PRP) have a high risk of severe vision loss. The aim of this study was to evaluate the effectiveness of single-dose intravitreal bevacizumab (IVB) after complete PRP in patients with refractory PDR. Patients with retinal neovascularization (NV) secondary to diabetes mellitus and re...

OBJECTIVES To evaluate the effectiveness of a single intra-articular injection of hylan G-F 20 (Synvisc) for symptomatic first metatarsophalangeal joint (MTPJ) osteoarthritis (OA). METHODS Participants (n = 151) with symptomatic first MTPJ OA were randomly allocated to receive up to 1 ml intra-articular injection of either hylan G-F 20 or placebo (saline). Participants and assessors were blin...

The intracerebral injection of N-methyl-D-aspartate (NMDA) has been proposed as a model for hypoxic-ischemic insult in the immature brain. In this light, the aim of this study was to describe the time course of the microglial reaction in the areas undergoing primary degeneration at the site of intracortical NMDA injection as well as in areas undergoing secondary anterograde and/or retrograde de...

PURPOSE To evaluate the results of intravitreal expansile gas injection, with or without recombinant tissue plasminogen activator (rtPA), followed by intravitreal bevacizumab injection for treatment of submacular hemorrhage (SMH) secondary to neovascular age-related macular degeneration (AMD). METHODS In this interventional case series, 5 eyes of 5 patients with SMH secondary to choroidal neo...

PURPOSE To determine the rate of postinjection endophthalmitis and compare microbial etiology and outcomes in office-based injection-related endophthalmitis versus those acquired after operating room procedures. METHODS Retrospective, observational case series. Consecutive cases of endophthalmitis seen at Retina Consultants of Houston between July 2000 and July 2010 were classified as postsur...

BACKGROUND Abscesses in the neck region can result from infection associated with injection of drugs into the neck muscles. To our knowledge, there have been no reports of osteomyelitis of the cervical vertebra and spinal cord compression secondary to an abscess in the neck. This case report describes the findings in a 9.5-month-old heifer with an abscess of the cervical spine secondary to inje...

PURPOSE To report the efficacy of intravitreal injection of bevacizumab 1.25 mg (IVB) in the treatment of choroidal neovascularization (CNV) secondary to angioid streaks (AS). METHODS Case review of two patients with CNV secondary to AS treated with three IVB with a 1-year follow up. RESULTS In both patients after 1 year fluorescein angiography and optical coherence tomography showed comple...

the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...
