Valsalva Retinopathy Presenting as Subretinal Hemorrhage.

Purpose: To describe a case of subretinal hemorrhage due to the Valsalva maneuver in a patient with no underlying chorioretinal disease.

Methods: History and clinical examination, optical coherence tomography (OCT), fluorescein, and indocyanine green angiography.

Results: We report a case of a 35-year-old man with a 4-day history of central vision loss in the left eye (OS) after a vomiting episode.

Direct Molecular Characterization of Acid-Fast Bacilli Smear of Nontuberculosis Mycobacterium Species Causing Pulmonary Tuberculosis in Guna Yala Region, Panama.

Mycobacterium tuberculosis (MTB) stands out as the main causative agent of pulmonary tuberculosis (TB). However, nontuberculous mycobacteria (NTM) species also have the potential to infect and cause TB in susceptible individuals. The objective of this study was to identify NTM species that cause public health problems in remote areas.

Occupational allergic disease: socio-epidemiological aspects from a specialized outpatient clinic in the city of Sao Paulo, Brazil.

Background: Occupational diseases involving the immune system are considered to be occupational allergic diseases (OAD); 15% of occupational diseases are allergic. The social consequences of OAD are significant for both workers and employers.

Objectives: To describe demographic and clinical characteristics of patients with OAD and their social outcomes.

Ocular adverse effects after facial cosmetic procedures: a review of case reports.

To review indexed literature concerning adverse ocular effects of the most common aesthetic facial procedures (light-emitting therapy, dermal fillers injection, and botulinum toxin). Literature search using three online databases - PubMed, SciELO, and Capes - selecting case reports, series of cases and reviews, with no language restriction, published in a period of the last twenty years (1995-2015). After reviewing 48 case reports and most recent reviews, the authors found the most common ocular adverse effects of dermal fillers were related to vascular occlusion; light-emitting therapy was associated with pigmented tissue damage leading to anterior uveitis and iris atrophy, and ptosis presented the higher relative risk associated with botulinum toxin.

[Basocellular epithelioma. Considerations on its histogenesis].

Twenty-nine cases of basal cell carcinoma were studied with immunoperoxidase techniques for the detection of carcinoembryonic antigen. Results presented in the text would indicate that a high percentage of basal cell carcinomas have sweat gland histogenetic origins and that this is independent of its morphologic features. The use of immunohistochemical techniques in the detection of biological markers demonstrates once again their value not only in identifying a disease but also in determining its histogenetic origins.
