Abstract
BACKGROUND To determine the efficacy and safety of intravitreal Avastin (bevacizumab) in the treatment of choroidal neovascularisation (CNV) secondary to pathological myopia (PM). METHODS This paper reports on a consecutive prospective study of patients with CNV secondary to PM who were treated with intravitreal bevacizumab (1.25 mg/0.05 ml). Patients underwent complete ophthalmic evaluation, which included best-corrected visual acuity testing measured with Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography (OCT), and fluorescein angiography. RESULTS There were 17 eyes of 17 patients, and the mean age was 55.4 (SD 10.0) years. At the 6-month follow-up, the mean visual acuity improved by 8.4 letters (p = 0.04). Forty-one per cent of patients increased at least one line, and 17% increased more than six lines. There were no cases of moderate vision loss (>or=3 lines) or severe vision loss (>or=6 lines). The mean OCT foveal thickness decreased by 79.6 mum (p = 0.002). Favourable outcomes were obtained in all subgroups. Patients received an average of one injection. As a complication, there was a tear of the retinal pigment epithelium. No other ocular or systemic side effects were observed. CONCLUSION In our study, intravitreal bevacizumab appeared to be safe and efficacious in eyes with CNV secondary to PM.

Abstract
PURPOSE To study the age distribution and survival in patients with uveal melanoma. METHODS A retrospective study was performed on 303 patients diagnosed with uveal melanoma. We analysed the clinical characteristics: age, gender, tumor size and origin, follow-up time, systemic state, survival time and cause of death. RESULTS The median age of the patients was 60.09 years. The 2-, 5-, and 10-year survival of patients less than 50 years of age at diagnosis was 91.41%, 81.83% and 61.45% respectively. The 2-, 5- and 10-year survival of patients equal to or older than 50 years was 90.86%, 73.18% and 58.28% respectively. No significant difference was found between these two age groups. When we considered a possible relationship between the sex factor and survival, in patients equal to or older than 50 years of age, we found a higher survival in men than in women (log-rank test; p=0.038). CONCLUSIONS Uveal melanoma in Spain has a similar age distribution to that of other countries, and it is not an infrequent diagnosis in patients under 40 years of age. Survival rates are also similar to that of other series. We have not found any significant difference between the age of our patients and the survival, although if we analysed the subgroups, we found that the men equal to or over 50 years of age had a better survival than the women of the same age.

Abstract
PURPOSE To study the prevalence of multiple neoplasms in patients affected by uveal melanoma in Spain and to relate these with survival. METHOD We carried out a longitudinal prospective study of the prevalence of multiple neoplasms in patients diagnosed to have a uveal melanoma during the years 1984-2005. The data has been analysed for the following variables: age, sex, date of diagnosis, affected eye, origin and tumoral size, classification according to COMS (Collaborative Ocular Melanoma Study), time of follow-up, presence of other neoplasms, current clinical state, date and cause of death. RESULTS Three hundred and five patients affected by uveal melanoma have been studied in the Ocular Oncology Unit of our institution; 24 patients (7.9%) had evidence in their medical reports of one or more additional neoplasms. Excluding cutaneous neoplasms originating in basal cells, this number reduced to 22 patients (7.2%). We did not find any statistically significant differences among the presentation age, sex or localization of the melanoma (ciliary body or choroid) and the presence or absence of a second neoplasm. When we analysed the proportion of patients with metastatic disease (both alive and dead) who presented with a second neoplasm (40.9%), we found a statistically significant relationship between these variables (Chi-square test, p=0.004). CONCLUSIONS We have observed a percentage of second neoplasms similar to that described in other international studies. We did not find a larger proportion with a second neoplasm according to the sex, age, or tumoral localization, nor did we observe a higher frequency of any particular second neoplasm. We have defined a relationship between metastasic uveal melanoma, and the development of a second neoplasm, which clearly indicates a need for increased systemic follow-up in such patients.

Abstract
BACKGROUND The objective of the study was to analyze optical coherence tomography (OCT) scan differences between patients with predominantly classic subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) treated with only photodynamic therapy (PDT) and patients treated with PDT combined with intravitreal triamcinolone acetonide (IVTA). METHODS In this prospective study, 61 patients were randomized to receive PDT (n = 30) or PDT combined with IVTA (n = 31). They were evaluated every 3 months with a refraction protocol for best-corrected visual acuity (VA) measured with Early Treatment Diabetic Retinopathy Study (ETDRS) charts, fluorescein angiography (FA), and OCT. When measuring foveal thickness on OCT scans, neuroretinal foveal thickness (NFT) was differentiated from outer high reflectivity band thickness (OHRBT). The main outcome measures were mean change in OCT measurements and correlation of VA and angiographic area of the lesion with OCT measurements. RESULTS At the 12-month follow-up, the mean change in NFT was not significantly reduced (P = 0.9), but the mean change in OHRBT was significantly lower (P = 0.004) in the group of patients who received combined therapy. There was no correlation between final VA and NFT in either patient group (P = 0.2). The final VA was significantly worse in eyes with a thicker OHRBT (P = 0.04) in the group of patients treated with only PDT. There was no correlation between angiographic area and NFT and OHRBT in either patient group (P > 0.3). There was a statistically significant difference between the pre-treatment angiographic area of the lesion and VA at the 12-month follow-up in the combined therapy group (P = 0.01), and more eyes treated with only PDT presented with intraretinal fluid at the last follow-up (P = 0.01). CONCLUSION Combined PDT+IVTA therapy was more effective than PDT alone at reducing OHRBT. This OCT measurement seems to be have a greater effect on VA than NFT.

Abstract
PURPOSE To determine whether intravitreal triamcinolone acetonide (IVTA) improves the efficacy of photodynamic therapy (PDT) with verteporfin in predominantly classic subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). DESIGN Prospective randomized study. PARTICIPANTS Sixty-one patients with predominantly classic subfoveal CNV secondary to AMD. METHODS Patients were randomized to receive PDT (n = 30) or PDT followed by approximately 11 mg IVTA (n = 31), with retreatment every 3 months when leakage was documented by fluorescein angiography. At baseline and each follow-up visit, best-corrected visual acuity (VA) was measured with Early Treatment Diabetic Retinopathy Study charts by a certified examiner masked to the patient's treatment, lesion size on fluorescein angiography, and foveal thickness on optical coherence tomography. MAIN OUTCOME MEASURES Mean change in VA (logarithm of the minimum angle of resolution [logMAR]) from baseline, percentage of patients losing fewer than 15 letters (3 lines) of VA, mean change in lesion size, mean change in foveal thickness, and retreatment rate. RESULTS At the 12-month follow-up, VA (mean logMAR change from baseline) was significantly better (P = 0.001) in the group of patients who received combined therapy. Seventy-four percent of patients treated with combined therapy compared with 61% treated with verteporfin alone lost fewer than 15 letters of VA (P = 0.78). Reduction in lesion size (P = 0.001) and in foveal thickness (P = 0.03) was significantly greater with combined therapy than with verteporfin. Retreatment rate was significantly lower (P = 0.04) in the combined therapy group. Triamcinolone-related adverse events included glaucoma (25.8%) and cataract progression (32%). CONCLUSIONS Combined PDT and IVTA therapy seemed to be more effective than PDT alone for managing predominantly classic subfoveal lesions secondary to AMD. The triamcinolone-related adverse events included glaucoma and cataract progression.

Abstract
AIM To use a model of economic evaluation to analyse the efficiency of therapy with the antiepileptic drugs indicated in recently diagnosed partial and generalised epilepsy. MATERIALS AND METHODS The treatment of partial epilepsy and generalised epilepsy in Spain was taken as the basis to design two flexible simulation models of the decision tree type. The time horizon of the study was one year and the perspective was that of the Spanish National Health System, and indirect costs were also included. Clinical effectiveness data were obtained from a review of the literature on clinical trials. Information about resources was obtained from the opinions of a panel of experts. Unitary costs of resources were drawn from Spanish databases (euro 2003). The findings of the study were expressed in terms of average cost per patient with each therapeutic strategy, as well as the incremental cost of the different treatment strategies with respect to valproic acid. RESULTS According to the literature that was reviewed, there are no differences in effectiveness from one antiepileptic drug to another. The incremental cost of the different therapeutic strategies, with respect to valproic acid, lies between 211 and 911 euros per patient and year in partial epilepsy, and between 1,355 and 1,297 euros per patient and year in the case of generalised epilepsy. CONCLUSIONS The use of sustained-release valproic acid in recently diagnosed partial and generalised epilepsy would allow savings to be made in resources, with respect to the other antiepileptic drugs, and can therefore be considered to be the most effective therapeutic option.

Abstract
The study of the singular hypersensitivity reactions to Anisakis simplex (A.s) proteins, may help us to undestand many of the unknown immune interactions between helmiths infections and allergy. We have developed a murine model of allergy to A. simplex, that mimics human A. simplex allergy to study the specific aspects of anaphylaxis induced by parasites. Male C3H/HeJ mice were intraperitoneally sensitized to A. simplex. Mice were then intravenous or orally challenged with A. simplex. Antigen-specific immunoglobulins, polyclonal IgE, anaphylactic symptoms, plasma histamine levels and cytokine profiles were determined. Comparative IgE immunoblot analyses were also performed. Specific IgE, IgG(1) and IgG(2a) were detected in sensitized mice since week 3. Polyclonal IgE raised and peaked with different kinetics. Intravenous A. simplex challenge produced anaphylaxis in mice, accompanied by plasma histamine release. Oral A. simplex challenge in similarly sensitized mice did not caused symptoms nor histamine release. Numerous A. simplex allergens were recognized by sensitized mouse sera, some of them similar to human serum. The A. simplex stimulated splenocytes released IL-10, IFN-gamma, IL-4, IL-13 and IL-5. We describe a new animal model of anaphylaxis. It exhibits characteristics of type I hypersensitivity reactions to Anisakis simplex similar to those observed in allergic humans. Different responses to i.v. or oral A. simplex challenges emerged, which did not reflect a window tolerization period. The cytokine profile developed (mixed Th(1)/Th(2) pattern) differed from the observed in classical models of anaphylaxis or allergy to food antigens. This model may permit to investigate the peculiar allergic reactions to parasitic proteins.

Abstract
This work describes, for the first time, the changes taking place in the antioxidative system of the leaf apoplast in response to plum pox virus (PPV) in different Prunus species showing different susceptibilities to PPV. The presence of p-hydroxymercuribenzoic acid (pHMB)-sensitive ascorbate peroxidase (APX) (class I APX) and pHMB-insensitive APX (class III APX), superoxide dismutase (SOD), peroxidase (POX), NADH-POX, and polyphenoloxidase (PPO) was described in the apoplast from both peach and apricot leaves. PPV infection produced different changes in the antioxidant system of the leaf apoplast from the Prunus species, depending on their susceptibility to the virus. In leaves of the very susceptible peach cultivar GF305, PPV brought about an increase in class I APX, POX, NADH-POX, and PPO activities. In the susceptible apricot cultivar Real Fino, PPV infection produced a decrease in apoplastic POX and SOD activities, whereas a strong increase in PPO was observed. However, in the resistant apricot cultivar Stark Early Orange, a rise in class I APX as well as a strong increase in POX and SOD activities was noticed in the apoplastic compartment. Long-term PPV infection produced an oxidative stress in the apoplastic space from apricot and peach plants, as observed by the increase in H2O2 contents in this compartment. However, this increase was much higher in the PPV-susceptible plants than in the resistant apricot cultivar. Only in the PPV-susceptible apricot and peach plants was the increase in apoplastic H2O2 levels accompanied by an increase in electrolyte leakage. No changes in the electrolyte leakage were observed in the PPV-inoculated resistant apricot leaves, although a 42% increase in the apoplastic H2O2 levels was produced. Two-dimensional electrophoresis analyses revealed that the majority of the polypeptides in the apoplastic fluid had isoelectric points in the range of pI 4-6. The identification of proteins using MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) and peptide mass fingerprinting analyses showed the induction of a thaumatin-like protein as well as the decrease of mandelonitrile lyase in peach apoplast due to PPV infection. However, most of the selected polypeptides showed no homology with known proteins. This fact emphasizes that, at least in Prunus, most of the functions of the apoplastic space remain unknown. It is concluded that long-term PPV infection produced an oxidative stress in the leaf apoplast, contributing to the deleterious effects produced by PPV infection in leaves of inoculated, susceptible Prunus plants.

Abstract
PURPOSE To evaluate the anatomic-functional results and complications associated with the use of photodynamic therapy (PDT) with verteporfin in the treatment of choroidal neovascularization (CNV) secondary to angioid streaks (AS). METHODS The authors retrospectively evaluated 10 consecutive patients (10 eyes) with CNV secondary to AS. All patients were treated with standard PDT with verteporfin protocol. The primary outcome to evaluate was the proportion of cases that lost < 3 lines of visual acuity (VA) measured on ETDRS charts. Secondary outcomes were changes in the greatest linear dimension (GLD) and in the area of the lesion. Seven previously examined patients were used as a control group. RESULTS The mean duration of follow-up was 18 months (SD 9.2, range 6-36 months). In nine cases CNV was subfoveal and in one case, juxtafoveal. Mean VA was 20/126 at baseline (range 20/40-20/320) and 20/500 at the final examination (range 20/64-20/800). Three patients (30%) lost< 3 lines of VA. Four patients (40%) lost > or =6 lines of VA. The mean line change was -4.9 lines. The mean GLD went from 2861 microm at baseline (SD 1086.6, range 1350-4300 microm) to 4452 microm at last visit (SD 2564.2, range 1260-9450 microm). The mean area of the lesion was 3.78 mm(2) at baseline (SD 1.9, range 1.0-5.7 mm(2)) and 12.1 mm(2) at the final examination (SD 15.1, range 0.8-50.6 mm(2)). One patient developed a subfoveal rip of the retinal pigment epithelium. In the control group, the mean duration of follow-up was 15 months (SD 2.4, range 12-18 months). At baseline, the mean VA was 20/160 (range 20/100-20/320) and the mean GLD was 2685 microm (SD 676.8, range 1800-3500 microm). At the last examination, mean VA was 20/640 (range: 20/400-20/800) and mean GLD was 5528 microm (SD 2106.90, range 3500-8000 microm). CONCLUSION PDT with verteporfin does not seem to be a good treatment for stabilization of VA and lesion size in CNV secondary to AS, although the overall results seem to be slightly better in the group of patients treated with PDT than in the control group.

Abstract
BACKGROUND The induction of an immune response to a biologically inert soluble protein requires an adjuvant. Here we have examined whether intact grains of pollen display such adjuvant effect, accounting for the immunogenic activity of pollen protein allergens that are devoid of intrinsic pro-inflammatory/adjuvant property. METHODS Human monocyte-derived dendritic cells (DCs) were cultured with intact grains of grass or ragweed pollen for 48 h. The state of DCs maturation was analyzed by FACS and their cytokine production by ELISA. T cell priming activity of DCs was examined in co-cultures with naïve cord blood-derived CD4(+) T cells. RESULTS Contact with grains of pollen induced a distinct maturation program in immature DCs. Pollen up-regulated the expression of CD54, CD80, CD83, CD86, HLA-DR, CCR7, and CD40 on DCs. Moreover, CCR5 expression was up-regulated by pollen but suppressed by LPS. In sharp contrast to LPS-stimulated DCs, pollen-treated DCs did not produce cytokines [interleukin (IL)-10, IL-12, tumor necrosis factor (TNF)-alpha] but retained the ability to secrete high levels of these cytokines upon simulation with soluble CD40 ligand and interferon (IFN)-gamma. Pollen-primed DCs strongly stimulated the proliferation of allogeneic naïve CD4(+) T cells and promoted their development into effector cells producing high levels of IL-5 and IL-13 together with moderate levels of IFN-gamma and IL-4. CONCLUSION Intact grains of pollen induce activation and maturation of DCs in vitro. Similar mechanisms may be effective in vivo, suggesting that pollen grain is not only an allergen carrier but also acts as an adjuvant in the induction phase of the allergic immune response.

Abstract
Cannabinoid receptors and the endocannabinoids anandamide and 2-arachidonoylglycerol have been suggested to regulate food intake in several animal phyla. Orthologs of the mammalian cannabinoid CB(1) and CB(2) receptors have been identified in fish. We investigated the presence of this endocannabinoid system in the brain of the goldfish Carassius auratus and its role in food consumption. CB(1)-like immunoreactivity was distributed throughout the goldfish brain. The prosencephalon showed strong CB(1)-like immunoreactivity in the telencephalon and the inferior lobes of the posterior hypothalamus. Endocannabinoids were detected in all brain regions of C. auratus and an anandamide-hydrolysing enzymatic activity with features similar to those of mammalian fatty acid amide hydrolase was found. Food deprivation for 24 h was accompanied by a significant increase of anandamide, but not 2-arachidonoylglycerol, levels only in the telencephalon. Anandamide caused a dose-dependent effect on food intake within 2 h of intraperitoneal administration to satiated fish and significantly enhanced or reduced food intake at low (1 pg/g body weight) or intermediate (10 pg/g) doses, respectively, the highest dose tested (100 pg/g) being inactive. We suggest that endocannabinoids might variously contribute to adaptive responses to food shortage in fish.
