Background: As part of efforts to control Japanese encephalitis (JE), the World Health Organization is producing a set of standards for JE surveillance, which require the identification of patients with acute encephalitis syndrome (AES). This review aims to provide information to determine what minimum annual incidence of AES should be reported to show that the surveillance programme is active.

No copy number changes were associated exclusively with metastatic CoMs. However, further investigation of the role of CDKN1A and RUNX2 in CoMs development and that of MLH1, TIMP2, MGMT, and ECHS1 in metastatic CoMs is warranted. Validation of the observed gene and chromosome arm copy number changes in a larger cohort of primary and metastatic CoMs is necessary to identify the patients at highest risk for CoMs metastasis.

The most common intraocular vascular tumours are choroidal haemangiomas, vasoproliferative tumours, and retinal haemangioblastomas. Rarer conditions include cavernous retinal angioma and arteriovenous malformations. Options for ablating the tumour include photodynamic therapy, argon laser photocoagulation, trans-scleral diathermy, cryotherapy, anti-angiogenic agents, plaque radiotherapy, and proton beam radiotherapy.

ABSTRACT.Purpose: Almost 40% of uveal melanomas (UM) are fatal, because of metastatic disease that usually involves the liver. Partial or complete deletion of chromosome 3 (i.e., monosomy 3) is a strong predictor of metastatic mortality; however, genetic analysis is not always possible. The aim of this study was to determine whether heat shock protein 27 (HSP-27) protein expression could reliably predict prognosis. Methods: Immunohistochemical analysis of HSP-27 protein expression was performed on formalin-fixed, paraffin-embedded sections from 99 UM of known chromosome 3 status, as determined by multiplex ligation-dependent probe amplification. Slides were evaluated blind by three independent observers. The percentage of tumour cells staining for HSP-27 was categorized as: 0 (<1%); 1 (1-24%); 2 (25-49%); 3 (50-74%) or 4 (>74%). The staining intensity was categorized as: 0 (no staining); 1 (weak); 2 (moderate) and 3 (strong). These two categories were multiplied together to obtain the HSP-27 expression score. All data were processed in spss for statistical analyses. Results: Heat shock protein 27 score was lower in monosomy 3 melanomas than in disomy 3 tumours (p < 0.001; Mann-Whitney U-test). An 'accelerated failure time model' was used to generate predicted survival for all patients included in the study. Kaplan-Meier analysis indicated a significantly decreased predicted 8-year survival rate for patients with an HSP-27 Score £6 (p = 0.03; Log rank test). Predicting monosomy 3 was enhanced by considering the HSP-27 score together with basal tumour diameter, melanoma cytomorphology and mitotic rate. Conclusions: Low HSP-27 expression correlates with monosomy 3 in UM and with increased predicted mortality. When assessed together with other clinical and pathological variables, the HSP-27 score enhances estimation of survival probability.
