Ten years' blindness of the right eye: A rare presentation of an orbital melanoma.

Benign and malignant orbital tumours develop from the orbit or invade it from the surrounding tissues. Ocular melanoma is a rare but potentially devastating malignancy arising from the melanocytes of the uveal tract, conjunctiva, or orbit. The poor overall survival depends mainly on its high metastatic rate.

Prevalence of a decreased FEV3/FEV6 ratio in symptomatic smokers with preserved lung function.

Background: The ratio of forced expiratory volume in 3 seconds to forced expiratory volume in 6 seconds (FEV3/FEV6) has been proposed as an index of peripheral airway disease, and could be decreased in patients at risk for COPD. However, the prevalence of FEV3/FEV6 decrease has never been assessed in patients attending a pneumology clinic. Here we set out to assess the prevalence of a decreased FEV3/FEV6 in smokers with symptoms of chronic bronchitis, and to test its predictive value for COPD diagnosis.

Is there still a role for cytotoxic chemotherapy after targeted therapy and immunotherapy in metastatic melanoma? A case report and literature review.

Metastatic melanoma has long been considered to have a very poor prognosis and to be chemo-resistant. However, a subgroup of patients with metastatic melanoma presents remarkable responses to chemotherapeutic agents, even in the absence of a response to modern targeted therapies and immunotherapies; accordingly, determining predictive biomarkers of the response to chemotherapies for metastatic melanoma remains a priority to guide treatment in these patients. We report a case study of a patient with B-Raf proto-oncogene serine/threonine kinase-mutated metastatic melanoma harbouring many genetic mutations.
