Abstract
PURPOSE To investigate whether interleukine-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) are related with macular oedema in patients with branch retinal vein occlusions (BRVOs). DESIGN Retrospective case-control study. PARTICIPANTS Nineteen patients who had macular oedema due to BRVO and nine patients with non-ischaemic ocular diseases (control group). METHODS Macular oedema was examined by optical coherence tomography. Both venous blood and vitreous samples were obtained at the time of vitreoretinal surgery. IL-8 and MCP-1 levels in vitreous fluid and plasma were determined with enzyme-linked immunosorbent assay kits. Variables were compared with the Mann-Whitney U-test, Wilcoxon's signed-ranked test, and the chi2-test, when appropriate. To examine correlations, Spearman's rank-order correlation coefficients were calculated. Statistical significance was set at P<0.05. RESULTS The vitreous fluid levels of IL-8 (median: 63.5 pg/ml) and MCP-1 (median: 1522.4 pg/ml) were significantly higher in the patients with BRVO than in the control group (median: 5.1 and 746.5 pg/ml respectively; P<0.001 and <0.001 respectively). Vitreous IL-8 and MCP-1 were significantly correlated in patients with BRVO (P=0.009). CONCLUSIONS Both IL-8 and MCP-1 were elevated in the vitreous fluid of patients with BRVO and macular oedema. Both chemokines may contribute to the pathogenesis of macular oedema in patients with BRVO.

Abstract
BACKGROUND Sitaxentan inhibits the metabolism of warfarin, resulting in a need for adjustment of warfarin dose when both drugs are coadministered. We report the long-term effects on bleeding of acenocoumarol co-administered as part of conventional therapy for pulmonary hypertension with sitaxentan in a subset of patients enrolled in the Sitaxentan To Relieve ImpaireD Exercise-3 (STRIDE-3) study. MATERIALS AND METHODS STRIDE-3 is an ongoing, long-term, open-label trial, evaluating the safety and efficacy of sitaxentan, 100 mg once daily, in patients with pulmonary arterial hypertension. Information on bleeding events was collected prospectively, including the type of event, severity, anticoagulant use and investigator attribution of causality. Coagulation tests were performed on a monthly basis. A clinically significant interaction was defined as an international normalized ratio (INR) >/= 5.0, or any minor bleeding event plus an INR > 2.0 and < 5.0. RESULTS Of 55 patients enrolled in STRIDE-3, 50 received acenocoumarol. Average follow-up was 158.6 +/- 57.6 weeks. The average dose of anticoagulant therapy was 3.9 +/- 1.3 mg week(-1) (range, 1.5-7.0 mg week(-1)). Following treatment, an INR >/= 5 in at least one INR determination was observed in 13 patients, although none of these patients had a clinically significant bleeding event. Dose reductions in acenocoumarol were performed to adjust target INR to 1.5-2.0. Two patients died of massive haemoptysis, but these episodes were not attributed to a drug interaction. Four patients with an INR > 2.0 and < 5.0 experienced a minor bleeding event (nosebleeds/gingivitis). CONCLUSIONS No clinically significant bleeding events were recorded with coadministration of sitaxentan and acenocoumarol in this patient subgroup. These results suggest that coadministration of sitaxentan and acenocoumarol is clinically manageable and well tolerated.

Abstract
Background Multiple sclerosis (MS) is associated with human leukocyte antigen (HLA) HLA–DRB1*15. Recent evidence that CD8 T cells are implicated in MS suggests that HLA class I may also contribute. An association of HLA–A*02 and A*03 alleles has been described. Objectives We examined the influence of HLA–A*02 and HLA–A*03 in Portuguese patients with MS, independently of HLA–DRB1*15 using a logistic regression model. Conclusions DRB1*15 increased the risk of developing MS and HLA–A*02 decreased the risk. A*03 had no effect. To analyze if HLA–A*02 association was independent from DRB1*15, an interaction between these two alleles was introduced in the model; no significant interaction was found.

Abstract
We present a new determination of the parity of the neutral pion via the double Dalitz decay pi0-->e+e-e+e-. Our sample, which consists of 30,511 candidate decays, was collected from KL-->pi0pi0pi0 decays in flight at the KTeV-E799 experiment at Fermi National Accelerator Laboratory. We confirm the negative pi0 parity and place a limit on scalar contributions to the pi0-->e+e-e+e- decay amplitude of less than 3.3% assuming CPT conservation. The pi0gamma*gamma* form factor is well described by a momentum-dependent model with a slope parameter fit to the final state phase-space distribution. Additionally, we have measured the branching ratio of this mode to be B(pi0-->e+e-e+e-)=(3.26+/-0.18)x10(-5).

Abstract
The Fermilab KTeV experiment has searched for lepton-flavor-violating decays of the K(L) meson in three decay modes. We observe no events in the signal region for any of the modes studied, and we set the following upper limits for their branching ratios at the 90% C.L.: BR(K(L) --> pi(0) micro(+/-) e(-/+)) <7.6 x 10(-11); BR(K(L) --> pi(0)pi(0) micro(+/-) e(-/+)) <1.7 x 10(-10); BR(pi(0) --> micro(+/-) e(-/+)) <3.6 x 10(-10). This result represents a factor of 82 improvement in the branching ratio limit for K(L) --> pi(0) micro(+/-) e(-/+) and is the first reported limit for K(L) --> pi(0)pi(0) micro(+/-) e(-/+).

Abstract
This Letter is the first report of the K{L}-->pi{+/-}e{-/+}nue{+}e{-} decay. Based on 19 208+/-144 events, we determine the branching fraction, B(K{L}-->pi{+/-}e{-/+}nue{+}e{-}M_{e{+}e{-}}>5 MeV/c{2},E{e{+}e{-}}{*}>30 MeV)=(1.285+/-0.041)x10{-5}, and Gamma(K{e3ee}M{e{+}e{-}}>5 MeV/c{2})/Gamma(K{e3})=[4.57+/-0.04(stat)+/-0.14(syst)]x10{-5}. This ratio agrees with a theoretical prediction based on chiral perturbation theory (ChPT) calculated to O(p{4}). The measured kinematical distributions agree with those predicted by just ChPT O(p{4}), but show significant disagreement with ones predicted by leading-order ChPT.

Abstract
Behçet's disease (BD) is a chronic, multisystemic, inflammatory process of uncertain origin. Diagnosis criteria consist of recurrent oral ulceration plus two of the following: genital ulceration, ocular and skin lesions, and positive pathergy test. Pulmonary embolism and, especially intracardiac thrombi, are very rare. We report the case of a patient with BD presenting with bilateral pulmonary embolism and intracardiac mass in right atrium.
