ReviewProposal for a multidisciplinary approach to the patient with morbid obesity: the St. Franciscus Hospital morbid obesity program.
Morbid obesity is a serious disease as it is accompanied by substantial co-morbidity and mortality. The prevalence is increasing to an alarming extent, in Europe as well as in the United States. In the past few decades, bariatric surgery has developed and gained importance. ⋯ The importance of a standardized protocol, the use of selection criteria, and a multidisciplinary approach have been stressed but not yet described in detail. Therefore, in this article, the multidisciplinary approach and the treatment protocol that have been applied in our hospital for more than 20 years are set out in a detailed manner. The application of a strict protocol may help to select and follow-up motivated patients and to organize multidisciplinary research activities.

Comparative StudyThe value of C-reactive protein as a marker of systemic inflammation in stable chronic obstructive pulmonary disease.
Systemic aspects of chronic obstructive pulmonary disease (COPD) include oxidative stress and altered circulating levels of inflammatory mediators and acute-phase proteins. C-reactive protein (CRP) reflects total systemic burden of inflammation in several disorders and has been shown to upregulate the production of proinflammatory cytokines. The aim of this study was to evaluate circulating CRP levels to determine the value of CRP as a biomarker of systemic inflammation and as an indicator of malnutrition or severity of COPD in stable COPD patients in comparison to the proinflammatory cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). ⋯ The present study confirms that circulating CRP levels are higher in stable COPD patients and may thus be regarded as a valid biomarker of low-grade systemic inflammation. In addition, CRP is significantly higher in COPD patients with a low BMI and thus, together with TNF-alpha, may be considered an indicator of malnutrition in COPD patients.

In 1997, a German group demonstrated that the antigen of the biomarker EMA (endomysial antibodies) in coeliac disease is a calcium-dependent thiol enzyme, transglutaminase type 2 (TG2). This most important discovery opened up an exciting field of research aimed at a better understanding of the pathogenesis of coeliac disease, a T-cell-driven autoimmune disorder with a prevalence of about 1%. The accidental activation of TG2, possibly caused by a stress-induced local deficiency of zinc in the intestinal wall, might play a key role where the enzyme catalyzes an atypical deamidation of specific glutamine residues of food gliadins. ⋯ These exciting developments might stimulate research within other fields of autoimmune disorders. With its focus on TG2, this review highlights some of the intriguing mechanisms of the pathogenesis of coeliac disease, such as the structure of the neo-antigen, the involvement of calcium and zinc, and the effects of coeliac antibodies on TG2 activity. Moreover, the many pitfalls due to dubious laboratory practice are addressed, as is the potential when a fundamental biological mechanism is understood at the molecular level.

Case ReportsSevere hemorrhagic syndrome due to similarity of drug names.
The names of many drugs look or sound like those of other drugs, which leads to confusion and potentially harmful medication errors. We report a nearly fatal permutation between two drugs including a vitamin K antagonist that resulted in a 68-year-old man being admitted to the emergency department with severe, spontaneous hemorrhagic syndrome. Such problems can be alleviated through actions by regulatory agencies, pharmaceutical manufacturers, health care professionals, and patients.

Comparative StudyPostmenopausal Canarian women receiving oral glucocorticoids have an increased prevalence of vertebral fractures and low values of bone mineral density measured by quantitative computer tomography and dual X-ray absorptiometry, without significant changes in parathyroid hormone.
Daily doses higher than 7.5 mg/daily of prednisone or equivalents confer a great risk of vertebral and hip fractures with a clear dose dependence of fracture risk. Information regarding the utility in assessing trabecular bone mineral density by quantitative computer tomography (QCT) in these patients, either in the Canaries or in Spain, is lacking. Moreover, in this setting, the importance of secondary hyperparathyroidism is still controversial. ⋯ In postmenopausal Canarian women, chronic glucocorticoid therapy is associated with low bone mineral density, measured either by DXA or QCT, with evidence of low turnover and high prevalence of fractures without significant changes in PTH. DXA and QCT provide similar information in the assessment of this high risk population.
