Melanoma immunotherapy has been an area of intense research for decades, and this work is now yielding more tangible results for patients. Work has focused on 4 main areas: cytokine therapy, administration of immune-modulating antibodies, adoptive T-cell therapy, and vaccines. Cytokine therapy is an established treatment for advanced melanoma, and immune-modulating antibodies have recently emerged as an exciting new area of drug development with efficacy now established in a phase III trial. ⋯ A review of the field of melanoma immunotherapy is provided here, with emphasis on those agents that have reached clinical testing. Novel strategies to induce the immune system to attack melanomas are reviewed. In the future, it is envisioned that immunotherapy will have further application in combination with cytotoxic and targeted therapies.

Irritable bowel syndrome is a functional gastrointestinal illness, defined by symptoms. Irritable bowel syndrome has been described as a biopsychosocial condition, in which colonic dysfunction is affected by psychological and social factors. As a result of this unusual constellation, irritable bowel syndrome may be subject to cultural variables that differ in different parts of the globe. ⋯ We describe our own research studies that have demonstrated possible adverse effects on disease severity from relationship conflict, attribution of symptoms to physical rather than emotional cause, and the belief that irritable bowel syndrome is enduring and mysterious. Also described is our finding that symptom patterns may differ significantly between different geographic locations. Finally, we discuss the importance of "cultural competence" on the part of healthcare professionals in regard to caring for patients of diverse cultural backgrounds.

Despite significant research efforts, a therapy to slow or halt the progression of Parkinson's disease ("neuroprotection") remains elusive. The discovery of such a therapy will likely require important observations from a number of perspectives: basic science investigation, clinical research, and careful observation in medical practice. Any possible insights will require confirmation in rigorous clinical trial testing. Combining the useful insights from all perspectives may be the most promising approach to discovering a neuroprotective therapy.

Malignant gliomas are the most common primary brain tumors in adults and carry a dismal prognosis. Despite aggressive therapy with maximal safe surgical resection, radiation and chemotherapy, these tumors invariably are refractory to or become resistant to treatment and recur. Gliomas are highly infiltrative cancers and display remarkable genetic heterogeneity making them challenging to treat. ⋯ In addition, the growing body of research in cancer immunology as well as cancer stem cells has made inroads in our understanding of tumorgenesis. Translational research has been particularly crucial to the development of these therapies as much preclinical and clinical work is needed to develop the rationale for treatments, to develop biomarkers of drug activity and to elucidate mechanisms of resistance. This brief overview will discuss some of the pivotal advances made in the pursuit of improved outcomes and survival for patients with this devastating disease.
