Fibromyalgia (FM) and chronic fatigue syndrome (CFS) are clinically overlapping stress associated disorders. Neuroendocrine perturbations have been noted in both syndromes, and they are more common in women, suggesting abnormalities of gonadal steroid hormones. We tested the hypothesis that women with FM and CFS manifest abnormalities of the hypothalamic-pituitary-gonadal (HPG) hormonal axis. ⋯ There is no indication of abnormal gonadotropin secretion or gonadal steroid levels in this small, but systematic, study of HPG axis function in patients with FM and CFS.

The concept that gut inflammation is implicated in the pathogenesis of spondyloarthropathies (SpA) has long been considered. Subclinical intestinal inflammation has been reported in adult patients with SpA by histological examination of intestinal biopsies. We assessed the presence of gut inflammation by abdominal 99mTc-hexamethyl propylene amine oxime (99mTc-HMPAO) labeled leukocyte scintigraphy in a group of children and adolescents with HLA-B27 positive SpA without gastrointestinal (GI) symptoms, and correlated the scintigraphic results to disease activity. ⋯ The presence of intestinal leukocyte uptake only in patients with active joint disease, even if intestinal inflammatory changes were minimal and clinical gut manifestations were absent, supports the role of gut inflammation in the pathogenesis of joint disease in HLA-B27 positive patients with SpA.

Randomized Controlled Trial Clinical Trial
Double blind randomized clinical trial examining the efficacy of bupivacaine suprascapular nerve blocks in frozen shoulder.
To determine whether the pain, contracture, and disability associated with idiopathic frozen shoulder are diminished by a series of 3 indirect bupivacaine suprascapular nerve blocks delivered in an ambulatory care clinic. ⋯ The use of bupivacaine suprascapular nerve blocks was effective in reducing the pain of frozen shoulder at one month. Clinical studies with a larger number of subjects and a longer study period will help determine the duration and nature of the effect of bupivacaine suprascapular nerve blocks in treating the pain, disability, and glenohumeral joint contracture of frozen shoulder.

Multicenter Study Comparative Study
Development and testing of a systemic lupus-specific risk adjustment index for in-hospital mortality.
Valid comparison of patient outcomes among hospitals requires adjustment for differences in the severity of patients' illness. Disease-specific indexes of severity of illness may permit more accurate risk adjustment than generic indexes. The objective of this study was to develop a systemic lupus-specific risk adjustment index for in-hospital mortality, and to compare its performance to that of the generic Charlson index. ⋯ The SLE-specific risk adjustment index developed from diagnoses recorded in administrative discharge abstracts performed similarly to the generic Charlson index in correctly classifying mortality outcomes, but the SLE-specific index stratified patients by their level of risk of mortality better than the Charlson index. Adjustment for SLE-specific risks of mortality did not alter the association between hospital experience and the risk of in-hospital mortality.

Comparative Study Clinical Trial Controlled Clinical Trial
Evaluation of patient partners in the teaching of the musculoskeletal examination.
To evaluate student preferences and examination outcomes of 2 different methods of teaching musculoskeletal (MSK) medicine examination techniques. ⋯ Patient partner teaching is as effective a method of teaching clinical skills in MSK medicine as a traditional resident based form of teaching, with student benefits from patient feedback and greater "hands-on" opportunities. The assessment process should incorporate patient partners to assess the unique aspects of patient educator based teaching of MSK examination techniques.
