Coristoma óseo epibulbar: caso clínico y revisión de literatura / Epibulbar osseous choristoma: A clinical case and review of the literatura

Presentamos el caso de un preescolar varón de 3 años con un coristoma óseo epibulbar. El paciente presentaba una masa subconjuntival de consistencia dura de 8×10 mm en el cuadrante superotemporal del ojo derecho con vascularización y presencia de cilios largos de aproximadamente 8 a 10 mm que tocaban la superficie corneal. El estudio histopatológico evidenció la presencia de trabéculas de hueso compacto maduro rodeado de tejido fibroso, canales de Havers con anillos concéntricos de hueso laminar sin médula ósea y con osteocitos normales, lo cual definió el diagnóstico de coristoma óseo epibulbar. El coristoma óseo es el tipo más raro de coristomas oculares y debe considerar en el diagnóstico diferencial de los tumores epibulbares pediátricos

We present the case of a 3-year-old male child with an epibulbar bone choristoma. The patient presented with a hard consistency subconjunctival mass of 8 × 10 mm in the superior-temporal quadrant of his right eye along with vascularisation and a long cilium of approximately 8 to 10 mm that touched the corneal surface. The histopathology study showed the presence of trabeculae of mature, compact bone surrounded by fibrous tissue, as well as Havers channels with concentric rings of laminar bone without bone marrow, and with normal osteocytes which defined the diagnosis of epibulbar bone choristoma. Osseous choristoma is the rarest type of the ocular choristoma and should be considered as a differential diagnosis among paediatric epibulbar tumour

Vasa previa, diagnóstico prenatal y manejo obstétrico / Vasa previa, prenatal diagnosis and management

Vasa previa ocurre cuando los vasos umbilicales no protegidos por el tejido placentario o cordón umbilical se sitúan en el segmento uterino inferior, delante de la presentación fetal a menos de 2 cm del orificio cervical interno. Los factores de riesgo son inserción velamentosa de cordón, placenta previa, placenta succenturiata y técnicas de reproducción asistida. El diagnóstico mediante ecografía transvaginal y Doppler color permite objetivar la presencia de vasos fetales por delante de la presentación fetal. El manejo incluye la maduración fetal con corticoides y cesárea electiva antes del parto. Describimos un caso clínico ocurrido en nuestro hospital

Vasa praevia is a condition in which the umbilical vessels, not supported by either the umbilical cord or placental tissue, cross the foetal membranes of the lower segment within 2 cm of the internal cervical os. The risk factors are velamentous insertion of the cord, placenta praevia, a bilobed and succenturiate placenta, and the use of assisted human reproductive techniques. The antenatal diagnosis by transvaginal ultrasound and colour Doppler can be used during the routine second trimester ultrasound in women with high risk. When the diagnosis is made in the antenatal period, the safest form of delivery is an elective caesarean with administration of corticosteroids prior to the onset of labour. A case diagnosed in our hospital is presented

Post-traumatic intraocular ophthalmomyasis due to Phormia sp. / Oftalmomiasis intraocular postraumática por Phormia sp.

CLINICAL CASE: An 18 year-old male patient presented with an injury to the left eye caused by a firearm. He remained unconscious for 2 days in an agricultural area, had a visual acuity of non-perception of light, wounds with loss of substance in upper and lower eyelid, atalamia, hypotonia, corneal oedema, wound with uveal exposure and exit of larvae in zone II. He was subjected to evisceration of the left eye. DISCUSSION: An untreated open ocular traumatism is a risk factor for intraocular ophthalmomyiasis.

Characterization of Pseudomonas syringae pv. actinidiae biovar 3 on kiwifruit in north-west Portugal.

AIMS: Bacterial kiwifruit canker disease, caused by Pseudomonas syringae pv. actinidiae (Psa) was detected in north-west Portugal in 2010, and has since caused significant losses. The objectives of this work were to characterize the Portuguese population(s) of Psa and to define the actual prevalence of Psa biovars in the most productive kiwifruit region in Portugal. METHODS AND RESULTS: Isolates obtained from Actinidia deliciosa orchards were characterized by morphological, biochemical, physiological, fatty acids and molecular tests (PCR, BOX-PCR, duplex-PCR, multiplex-PCR and RFLP), phaseolotoxin, housekeeping and effector genes and pathogenicity. Results established that only Psa biovar 3 is present in the north-west of Portugal, despite phenotypic and genetic variability among the isolates. CONCLUSIONS: This work provides new information on P. syringae pv. actinidiae (Psa) genetic profile in Portugal, indicating for the first time, that two genetically different subpopulations of Psa biovar 3 are present. SIGNIFICANCE AND IMPACT OF THE STUDY: A new subpopulation of Psa biovar 3 was found for the first time in Portugal, contributing to increase knowledge about this population worldwide and to support further understanding of the impact of Psa.

Ovarian hydatid disease.

Hydatid disease, also known as Echinococcosis is a zoonosis caused by the larval stage of Echinococcus. The human cystic variant primarily affects liver and lungs. The pelvic location of the disease is a rare finding usually secondary to a ruptured liver cyst, although it may also appear as a primary lesion affecting the genital organs. Despite its rarity, in endemic areas, pelvic hydatid disease should be considered in the differential diagnosis of complex adnexal cystic mass, to make an appropriate treatment strategy. The suspected diagnosis is based on imaging studies and serodiagnostic techniques, in which a new field of research attempts to find a standardized test with sufficient sensitivity and specificity. We report a case of primary pelvic hydatid disease in postmenopausal women operated for suspected ovarian cancer.

Aplicación de un protocolo de levantamiento radiométrico en instalaciones de radiodiagnóstico / Application of a radiometric inventory protocol in radiodiagnostics facilities

A radiometric study was carried out in two Radiodiagnostic Units, with seven rooms being assessed. Methodology of the Radiodiagnostics Quality Control Protocol ARCAL XLIX (Cooperation Agreement for the Promotion of Nuclear Science and Technology in Latin America and the Caribbean) of the International Atomic Energy Agency (IAEA) was used. From radiation protection viewpoint, effective dose rates on surface for different relevant positions were calculated.The eigthy-five percent (85 percent) of assessed positions showed effective dose rates within limit values established in the ARCAL XLIX Protocol. Nevertheless, occupationally-exposed personnel (OEP) placed at position A (controlled area) -one meter distant from the phantom- was found to be exceeding by 7 the ARCAL XLIX advised values.

Se realizó un Levantamiento Radiométrico en dos servicios de imaginología con un total de 7 salas de radiodiagnóstico evaluadas. Se utilizó metodología del Protocolo de Control de Calidad en Radiodiagnóstico ARCAL (Acuerdo de Cooperación Regional para la promoción de la ciencia nuclear y tecnología en América Latina y el Caribe) XLIX del Organismo Internacional de Energía Atómica (OIEA). Se calcularon las tasas de dosis efectiva en superficie en diferentes posiciones de interés desde el punto de vista de la protección radiológica. El 85 por ciento de las posiciones evaluadas presentan tasas de dosis efectivas que cumplen con los valores límites establecidos en el protocolo ARCAL XLIX. No obstante el personal ocupacionalmente expuesto (POE) ubicado a un metro del simulador (área controlada) supera hasta en un factor 7 el límite propuesto en ARCAL XLIX.
