Isolated orbital mucoceles in the absence of obstructive sinus disease.

Orbital surgeons are quite familiar with the diagnosis and management of paranasal sinus mucoceles due their frequent involvement of the orbit. These benign masses form and expand following sinus outflow obstruction secondary to various causes including trauma, inflammation and malignancy, amongst others. The authors present two cases of isolated orbital mucoceles without associated sinus outflow obstruction. There were notably no connections between the paranasal sinuses and the lesions. The mucoceles were diagnosed following orbitotomies and excisional biopsies with confirmatory histopathology. These rare orbital lesions should be considered when evaluating cystic orbital lesions, and the orbital surgeon should be familiar with the proposed pathophysiology and treatment recommendations.

Ocular injuries from fireworks: the 11-year experience of a US level I trauma center.

PurposeCharacterize ocular trauma and visual outcomes from firework injuries at a level I trauma center.MethodsRetrospective review of all firework injuries at Harborview Medical Center between 2003 and 2013.ResultsThree hundred and twenty-seven patients sustained firework injuries, of which 100 (31%) sustained ocular injuries. The average age of all patients who sustained fireworks injuries was 24.2 years, 89% were male and 54% of injuries occurred within 48 h of 4 July. Ocular injuries were most commonly caused by mortars (24%) and rockets (22%). Rockets were associated with four times the frequency of ocular injuries as compared with non-ocular injuries (P<0.001). Spectators were more likely to sustain ocular injuries than non-ocular injuries (P=0.001). The most common injuries sustained were corneal abrasions (67%), hyphemas (42%), eyelid injuries (39%), and ruptured globes (17%). Twenty-eight percent of patients with ocular injuries required surgical intervention. Ruptured globes occurred in 17% of patients, with the majority being complex corneoscleral lacerations. Fifty-eight percent of patients who sustained ruptured globes were left with no light perception in the affected eye. Average follow-up was 188 days. Average visual acuity significantly improved from logMAR 1.8±1.6 at presentation to logMAR 1.3±1.8 at last follow-up.ConclusionsFirework-related ocular trauma frequently results in vision-threatening pathology. Prompt referral to and treatment by ophthalmologists is critical. This study documents the dangers inherent in the personal use of fireworks and provides data that may help guide public policy to decrease the frequency of these devastating injuries.

La siembra del M. leprae en el saco de la yema del embrion de pollo en desarrollo

1- Hemos inoculado gran cantidad de bacilos de ansen procedentes de lesiones lepromatosas, en el caso de la yema de huevos embrionados en distintos estados de incubación. 2- Hemos examinado los huevos, en intervalos, en búsqueda de bacilos ácidoresistentes (eliminado las posibilidades de M. avium). 3- Hemos hecho hasta 6 pases, en un caso, pudiendo considerar que el M. leprae, a nuestro juicio, no encuentra, en el saco de la yema del embrión de pollo, un ambiente favorable a su multiplicación. 4- Que a pesar de este resultado adverso aquí anotado, pensamos seguir estas investigaciones sobre las bases del mismo principio, con otro método de inoculación, los cuales publicaremos en el futuro.
