    Title Use of Facility Assessment Data to Improve Reproductive Health Service Delivery in the Democratic Republic of the Congo.
    Date May 2010
    Journal Conflict and Health

    Prolonged exposure to war has severely impacted the provision of health services in the Democratic Republic of the Congo (DRC). Health infrastructure has been destroyed, health workers have fled and government support to health care services has been made difficult by ongoing conflict. Poor reproductive health (RH) indicators illustrate the effect that the prolonged crisis in DRC has had on the on the reproductive health (RH) of Congolese women. In 2007, with support from the RAISE Initiative, the International Rescue Committee (IRC) and CARE conducted baseline assessments of public hospitals to evaluate their capacities to meet the RH needs of the local populations and to determine availability, utilization and quality of RH services including emergency obstetric care (EmOC) and family planning (FP).

    Title Sequential Bilateral Central Retinal Artery Occlusions in a Female Carrier of Fabry Disease.
    Date October 2009
    Journal Clinical & Experimental Ophthalmology
    Title Candida Glabrata Endophthalmitis Treated Successfully with Caspofungin.
    Date August 2006
    Journal Clinical Infectious Diseases : an Official Publication of the Infectious Diseases Society of America

    A 39-year-old man with Candida glabrata endophthalmitis was successfully treated with a 28-day course of intravenous caspofungin. Presence of underlying renal insufficiency and infection with a drug-resistant strain precluded use of amphotericin B or fluconazole. Intravitreal administration of antifungals and vitrectomy were not required. The role of caspofungin in Candida endophthalmitis is discussed.

    Title Aspergillus Terreus Endophthalmitis.
    Date September 2005
    Journal Scandinavian Journal of Infectious Diseases

    We report a case of Aspergillus terreus endophthalmitis and review the 4 previously reported cases. Immunosuppression, intravenous drug use, intraocular surgery or trauma, and a compatible clinical picture should raise suspicion of the diagnosis. This species often exhibits resistance to amphotericin B and outcomes are poor despite current therapies.

    Title The Autogenous Dermis-fat Orbital Implant in Children.
    Date February 2002
    Journal Journal of Aapos : the Official Publication of the American Association for Pediatric Ophthalmology and Strabismus / American Association for Pediatric Ophthalmology and Strabismus

    PURPOSE: The autogenous dermis-fat graft orbital implant is one alternative for volume augmentation in the adult anophthalmic socket. We have reviewed our experience with dermis-fat grafts after primary enucleation in the pediatric population. METHODS: We reviewed the clinic charts of all patients under 8 years of age who underwent primary enucleation combined with dermis-fat graft implantation. We assessed subsequent orbital growth by measuring lid and fissure symmetry, superficial soft tissue socket volume, prosthetic fit, and periorbital symmetry. All measurements were obtained by 2 of the authors. RESULTS: Eight children had primary enucleations combined with a dermis-fat implant (Table 1). Age at the time of surgery ranged from 1 week to 8 years. Indications for enucleation were retinoblastoma (4), malignant teratoid medulloepithelioma (1), blind, painful eye secondary to trauma (2), or phthisis secondary to end-stage retinopathy of prematurity (1). Two patients were lost to follow up at 3 months and 6 months post enucleation. The remaining 6 patients had between 1 year and 6 years of follow up. All implants maintained appropriate volume allowing proper prosthetic fit and facial symmetry. Two children experienced excessive growth of their implants, managed by surgical debulking. Two children developed a central graft ulcer, managed by superficial revision and reclosure. CONCLUSIONS: We have observed that dermis-fat grafts in pediatric primary enucleations demonstrate good maintenance of orbital soft tissue volume and periorbital symmetry. The complications of excessive dermis-fat growth or central ulceration were easily corrected. We feel this is a promising implant for the pediatric anophthalmic socket.

    Title Preventing Fetal Alcohol Syndrome.
    Date July 2000
    Journal Journal of Pediatric Health Care : Official Publication of National Association of Pediatric Nurse Associates & Practitioners
    Title Inflammatory Opacities of the Vitreous in Rifabutin-associated Uveitis.
    Date November 1996
    Journal American Journal of Ophthalmology

    PURPOSE: To describe rifabutin-associated uveitis with opacities in the inferior and posterior vitreous in three patients with acquired immunodeficiency syndrome. METHOD: Case reports of the three patients are presented. RESULTS: The patients, who were being treated with rifabutin and fluconazole, developed anterior and posterior uveitis. The posterior uveitis was characterized by white-yellow inflammatory opacities located in the inferior and posterior vitreous. Discontinuation of rifabutin and the start of topical corticosteroid therapy resulted in improvement of the uveitis and visual acuity. CONCLUSION: Recognition of rifabutin-associated uveitis with opacities in the inferior and posterior vitreous may prevent unnecessary invasive diagnostic and therapeutic procedures.

    Title Ocular Histoplasmosis with Retinitis in a Patient with Acquired Immune Deficiency Syndrome.
    Date December 1991
    Journal Ophthalmology

    Disseminated histoplasmosis is one of the life-threatening opportunistic infections associated with acquired immune deficiency syndrome (AIDS). A 29-year-old man with AIDS and disseminated histoplasmosis complained of a hazy spot in the vision of his left eye. Results of examination showed distinct creamy white intraretinal and subretinal infiltrates in both eyes. The patient died within a month from pulmonary infection with Histoplasma capsulatum and cytomegalovirus. Examination with light microscopy showed that the right and left eyes contained histoplasma yeast cells in lesions of retinitis, optic neuritis, and uveitis. These lesions contained variable numbers of lymphocytes and histiocytes. Electron microscopy of the histoplasma in tissue showed characteristic features. This case illustrates the funduscopic appearance and histopathology of histoplasmic retinitis, an uncommon although important ophthalmologic complication of AIDS.

    Title Membrane Bilayer Balance and Platelet Shape: Morphological and Biochemical Responses to Amphipathic Compounds.
    Date May 1988
    Journal Biochimica Et Biophysica Acta

    Activated platelets adopt a characteristic spiculate morphology. A wide variety of anionic and zwitterionic amphipathic compounds were found to effect a similar shape change and to cause the open canalicular system to become less prominent. Several cationic amphipaths reversed thrombin-, PAF-, and amphipath-induced spiculation and restored the discoid shape. Higher concentrations of cationic amphipaths caused the cells to assume spheroid and indented forms, and caused the canalicular system to appear more prominent. Three amphipaths were studied further to address possible mechanisms underlying their morphological effects. Dilauroylphosphatidylcholine was found to induce spiculation without causing the changes in protein phosphorylation and inositide metabolism generally associated with platelet activation. Two other amphipaths, chlorpromazine (which induced sphering) and dilauroylphosphatidylserine (which caused spiculation followed by sphering) caused specific changes in protein and/or lipid phosphorylation, which may be responsible for some, but not all, of the morphological effects of these compounds. To account for these findings, we propose that platelet shape can be influenced by changes in the plasma membrane bilayer balance. Agents that bind to the membrane outer monolayer are accommodated by spiculation; those that bind to the inner monolayer are accommodated by sphering.

    Title Separation of Phosphoinositides and Other Phospholipids by Two-dimensional Thin-layer Chromatography.
    Date March 1987
    Journal Analytical Biochemistry

    A simple, rapid, two-dimensional TLC system is presented which resolves the four phosphoinositide cycle phospholipids as well as all commonly encountered major and minor phospholipids. Ca2+-free lipid samples are loaded onto silica gel HL plates and developed first in 48:40:7:5 chloroform:methanol:water:concentrated ammonia, and then in 55:25:5 chloroform:methanol:formic acid. The method was applied successfully to human erythrocytes, human platelets, and BL/VL3 murine lymphoma cells.
