Summary: Coronary artery ectasia (CAE) is found in 0.3-5% of patients undergoing coronary angiography. Atherosclerosis is the main cause, followed by Kawasaki disease and infectious emboli. The exact pathogenesis has not been diagnosed as yet, but an inflammatory process is underlying. Symptoms, if present, are usually related to myocardial ischemia. Angiography is the mainstay for diagnosis. The prognosis is generally favorable. Thromboembolic complications are rare with antiplatelet therapy, and spontaneous rupture generally is rare but occurs more commonly in Kawasaki disease. Management varies from antithrombotic therapy to surgical ligation. Controlling coronary heart disease risk factors sharply affects the prognosis in patients with CAE.

Background: Goblet cell carcinoid (GCC) of the appendix is a rare neoplasm that share histological features of both adenocarcinoma and carcinoid tumor. While its malignant potential remains unclear, GCC's are more aggressive than conventional carcinoid. The clinical presentations of this neoplasm are also varied. This review summarizes the published literature on GCC of the appendix. The focus is on its diagnosis, histopathological aspects, clinical manifestations, and management.

HAL and SI made a small but statistically significant contribution to hip fracture prediction that was independent of age and BMD measurement.

A major impediment in the development of novel drugs for chronic obstructive pulmonary disease (COPD) has been the scarcity of a well-validated, robust, and easily obtainable intermediate end point such as serum biomarkers. To date the best serum biomarkers in COPD have been non-speci"c pro-in"ammatory molecules synthesized largely by extra-pulmonary organs. In COPD, an ideal biomarker would be one that (1) was produced mostly in the lungs (and was reliably measurable in the peripheral circulation using commercially available kits), (2) changed with the clinical status of patients or with relevant exposures; and (3) had inherent functional attributes that suggested a possible causal role in the pathogenesis of the disease. In this paper, we review one promising systemic biomarker that ful"lls some of these criteria, surfactant protein D (SPD).

Background: The different physiological repertoire of CA3 and CA1 neurons in the hippocampus, as well as their differing behaviour after noxious stimuli are ultimately based upon differences in the expressed genome. We have compared CA3 and CA1 gene expression in the uninjured brain, and after cerebral ischemia using laser microdissection (LMD), RNA amplification, and array hybridization.

We found a very high prevalence of osteoporotic BMD measurements in institutionalized adults with developmental disabilities. Lower heel and forearm BMD measurements were significantly and independently associated with prior fragility fractures in this population.
