Brain metastases from malignant melanoma have a poor prognosis, and treatment can be difficult because of rapid progression of the disease. To help define the treatment of this disease, we reviewed the published literature on brain metastases from melanoma. If a solitary metastasis is present, surgery might be beneficial, especially if systemic disease is absent. ⋯ External beam whole-brain radiation therapy can produce responses and frequently palliates symptoms, but as the sole therapy, it is unlikely to eradicate brain metastases. Chemotherapy may be gaining a role with newer agents that penetrate the blood-brain barrier. Combined modality therapy appears to be the future direction of treatment of multiple metastases.

Prevalence of severe hypovitaminosis D in patients with persistent, nonspecific musculoskeletal pain.
To determine the prevalence of hypovitaminosis D in primary care outpatients with persistent, nonspecific musculoskeletal pain syndromes refractory to standard therapies. ⋯ All patients with persistent, nonspecific musculoskeletal pain are at high risk for the consequences of unrecognized and untreated severe hypovitaminosis D. This risk extends to those considered at low risk for vitamin D deficiency: nonelderly, nonhousebound, or nonimmigrant persons of either sex. Nonimmigrant women of childbearing age with such pain appear to be at greatest risk for misdiagnosis or delayed diagnosis. Because osteomalacia is a known cause of persistent, nonspecific musculoskeletal pain, screening all outpatients with such pain for hypovitaminosis D should be standard practice in clinical care.

Case ReportsSudden progression of lumbar disk protrusion during vertebral axial decompression traction therapy.
Vertebral axial decompression (VAX-D) is a form of spinal traction that is widely promoted as an effective and safe treatment of degenerated and herniated lumbar intervertebral disks. Information targeted at the general public emphasizes that the treatment is completely risk-free. ⋯ To our knowledge, this is the first reported complication of VAX-D therapy. This case shows that VAX-D therapy has the potential to cause sudden deterioration requiring urgent surgical intervention.

Comparative StudyAssociation between hyperglycemia and increased hospital mortality in a heterogeneous population of critically ill patients.
To investigate the relationship between hyperglycemia and hospital mortality in a heterogeneous group of critically ill patients. ⋯ Even a modest degree of hyperglycemia occurring after intensive care unit admission was associated with a substantial increase in hospital mortality in patients with a wide range of medical and surgical diagnoses. Analysis of glucose values added predictive power above that achieved by APACHE II scores alone. These results have important implications for the glycemic management of critically ill patients.
