RESUMO
PURPOSE: The study was designed to prospectively evaluate the bacterial contamination of needles used for intravitreal injection during surgery. MATERIAL AND METHODS: Between December 2007 and December 2010, 549 eyes of 413 patients were treated with intravitreal injections of 1.25 mg bevacizumab. Of the patients 322 received a single injection and 91 multiple injections. Preoperatively the periorbital skin of all patients was treated with 10% povidone iodine (PVI) and the conjunctival sac was irrigated with 1% PVI. No pre-injection antibiotics were administered. Immediately after the injection the needles were rinsed 3 times in thioglycolate broth which was then cultured at 37°C for 5 days. As a negative control 73 sterile unused needles were treated in the same way. RESULTS: Out of the 549 needle points tested 8 (1,45%) were found to be contaminated after intravitreal injections. The isolated bacteria were coagulase negative Staphylococcus (n = 7), Propionibacterium acnes (n = 1) and Klebsiella pneumoniae (n = 1) (co-contamination in one case). CONCLUSION: Contamination of needles is minimal after prophylactic povidone iodine irrigation before intravitreal injections. Therefore, this prophylaxis technique is recommended before intravitreal injections in order to prevent postoperative infections.

RESUMEN En este trabajo presentamos nuestra experiencia en el tratamiento quirúrgico de 10 pacientes con Labio leporino unilateral y al mismo tiempo, el abordaje y corrección de la deformidad nasal presente en casi todos los casos. El tratamiento incluyó disecar delicadas estructuras anatómicas del labio y nariz para conseguir realinear elementos distorsionados y teniendo como meta conseguir una apariencia facial normal.
ABSTRACT In this work we present our experience in the surgical treatment of patient with Unilateral Cleft Lip and also, at the same time, the approach and correction of the nasal deformity present in almost all the cases. The treatment includes to dissect delicate anatomical structures of the lip and nose and thus achieve a realignment of the distorted elements and to reach a normal facial appearance.
