Because vitamin D deficiency has been previously reported in patients with systemic lupus erythematosus (SLE), we decided to examine the prevalence of vitamin D deficiency in Thai SLE patients, to identify possible independent factors affecting serum 25-hydroxyvitamin D(2) and D(3) [25(OH)] vitamin D levels, and to examine the associations of serum 25(OH) vitamin D and disease activity and damage in Thai SLE patients. ⋯ Vitamin D deficiency and insufficiency are common in SLE patients despite more than half of them taking vitamin D supplementations. Higher serum creatinine level and higher current daily glucocorticoid dose are associated with lower serum 25(OH) vitamin D levels. These patients may require higher doses of vitamin D supplementations.

The prevalence of spondyloarthritis (SpA) varies across populations. In Mexicans, the prevalence of SpA is still unknown. ⋯ The prevalence and sex distribution of patients classified with SpA in this community study--as well as that of patients diagnosed with AS--are consistent with those found in recent studies. Expert assessment of individuals with positive responses to questionnaires is relevant for the classification of IBP and SpA.

Chronic opioid therapy in the treatment of chronic nonmalignant pain has increased drastically over the past decade. This is a worrisome trend in general, but specifically, given pathophysiologic characteristics seen in fibromyalgia (FM) syndrome patients, the use of this class of medication deserves special scrutiny. We first describe the current understanding of the etiology and pathophysiology of FM, including the role of genetic and environmental factors in the development of this syndrome. ⋯ Next, we review the pharmaceutical treatment options for FM, including 3 Food and Drug Administration-approved medications, and the evolution of treatment guidelines since 2004. We then highlight the various consequences associated with the mechanism of action of opioids and the specific concerns for FM patients. Finally, summarizing the existing literature, we make the case that chronic opioid use is inappropriate in the treatment of FM because of the interaction of unique pathophysiologic characteristics of the patients and effects associated with chronic opioid use.

Review Case Reports
Dropped head syndrome in a patient with scleromyositis.
Dropped head syndrome (DHS) occurs in patients with severe weakness of the neck extensor muscles, of diverse origin, but most frequently because of neuromuscular diseases. Exceptionally, DHS may be the first manifestation of a systemic autoimmune disease. This report describes the case of a patient with DHS as a presenting sign of scleromyositis. We analyze the clinical features of the case and discuss the most important aspects of its pathogenesis and differential diagnosis.
