Phosphorylated STAT3 was observed in all cases with a strong and diffuse nuclear pattern. MYC rearrangements were not identified in any tumor, but MYC gains and amplification were detected in six cases and one case, respectively. MYC protein was expressed in all tumors independently of MYC gene alterations. These results indicate that ALK-positive large B-cell lymphomas express a complete plasmablastic differentiation program but, contrary to plasmablastic lymphomas, do not have MYC rearrangements. STAT3 is constantly activated and may be an alternative mechanism to promote MYC expression in these tumors. The relevance of the ALK/STAT3 SHP099 pathway in the pathogenesis of ALK-positive

large B-cell lymphomas may offer an attractive target for new therapies.”
“Aim British military ophthalmologists have not been deployed in support of operations since 2003. Eye injuries in British forces receive definitive treatment on return to the United Kingdom. We report the injury

patterns, management strategies, and outcomes for eye injuries in British Armed Forces in Iraq and Afghanistan.\n\nMethods Retrospective consecutive case series of eye injuries in British Armed Forces in Iraq or Afghanistan from July 2004 to May 2008. Outcomes assessed by final best-corrected visual acuity (VA; few patients lost to follow-up), rates of endophthalmitis, and proliferative vitreoretinopathy (PVR).\n\nResults There were 630 cases of major trauma, 63 sustained eye injuries (10%), and 48 sustained buy IPI-145 significant eye injuries. There were 21 open-globe injuries: 9 ruptures and perforating injuries, of which 7 were enucleated/eviscerated; 11 intraocular foreign body (IOFB) injuries, of which 1 was eviscerated. Primary repair was combined with posterior segment reconstruction in 9/11 cases with IOFB. Mean time to primary repair was 1.9 days (range 0-5). Intravitreal antibiotics were given at primary repair in five cases. All cases received early broad-spectrum systemic antibiotics. Median final

VA was logMAR 0.25 excluding evisceration/enucleations. There were two cases of PVR and none of endophthalmitis.\n\nConclusions The number of eye injuries as a proportion of all casualties is GSK1838705A supplier lower than recently reported. The injuries are more severe than in civilian practise. The outcomes were comparable with previous reports, this demonstrates that, in certain cases, primary repair can be safely delayed beyond 24 h in the patient’s best interests, in order to optimise the conditions for treatment.

“Objective. Fractures of the hyoid bone are rare occurrences. They are mainly caused by strangulation/asphyxiation injuries, trauma to the neck, and motor vehicle accidents (MVAs). As a result of their rarity, proper treatment guidelines are not in place for dealing with these injuries.
