Abstract Background To gain more insight into the involvement of inflammatory response and neurohumoral activation in Takotsubo cardiomyopathy (TTC), we investigated C-reactive protein (CRP), ...leukocytes, plasma catecholamines levels, iodine 123 meta-iodobenzylguanidine (123 I-mIBG) myocardial uptake, myocardial perfusion (thallium 201 201 Tl or technetium Tc 99m-tetrofosmin myocardial single photon emission computed tomography SPECT), and metabolism (fluorine 18-fluorodeoxyglucose positron emission tomography). Methods and Results Inflammatory status and brain natriuretic peptide (BNP) levels in 17 patients with TTC were compared with 14 age-matched patients. In TTC, elevated levels of CRP were evidenced on admission, reaching a peak in the following days ( P < .01). CRP levels were correlated to baseline left ventricular ejection fraction (LVEF) and BNP levels ( P < .05). Leukocytes were correlated to BNP and noradrenaline levels. Myocardial123 I-mIBG SPECT showed a reduced activity in the midventricle and apex corresponding to 35% ± 23% of the total myocardial mass, partially reversible at follow-up. An identical pattern was retrieved when assessing myocardial glucose metabolism. At rest, no relevant abnormalities of myocardial perfusion could be evidenced at the subacute phase. Conclusion Inflammatory status in TTC was related to LVEF impairment and to the extent of neurohormonal activation. The hypothesis of a catecholamine-induced myocardial “stunning” is emphasized by the evidence of a reduced123 I-mIBG myocardial activity, impairment of myocardial glucose metabolism, and wall motion kinetic after the same temporospatial distribution.
Background Primary hyperparathyroidism (PHPT) may be related to a single gland disease or multiglandular disease, which requires specific treatments. At present, an operation is the only curative ...treatment for PHPT. Currently, there are no biomarkers available to identify these 2 entities (single vs. multiple gland disease). The aims of the present study were to compare (1) the tissue metabolomics profiles between PHPT and renal hyperparathyroidism (secondary and tertiary) and (2) single gland disease with multiglandular disease in PHPT using metabolomics analysis. Methods The method used was1 H high-resolution magic angle spinning nuclear magnetic resonance spectroscopy. Forty-three samples from 32 patients suffering from hyperparathyroidism were included in this study. Results Significant differences in the metabolomics profile were assessed according to PHPT and renal hyperparathyroidism. A bicomponent orthogonal partial least square-discriminant analysis showed a clear distinction between PHPT and renal hyperparathyroidism (R2 Y = 0.85, Q2 = 0.63). Interestingly, the model also distinguished single gland disease from multiglandular disease (R2 Y = 0.96, Q2 = 0.55). A network analysis was also performed using the Algorithm to Determine Expected Metabolite Level Alterations Using Mutual Information (ADEMA). Single gland disease was accurately predicted by ADEMA and was associated with higher levels of phosphorylcholine, choline, glycerophosphocholine, fumarate, succinate, lactate, glucose, glutamine, and ascorbate compared with multiglandular disease. Conclusion This study shows for the first time that1 H high-resolution magic angle spinning nuclear magnetic resonance spectroscopy is a reliable and fast technique to distinguish single gland disease from multiglandular disease in patients with PHPT. The potential use of this method as an intraoperative tool requires specific further studies.
Abstract Atypical (bizarre) leiomyoma is a benign uterine smooth-muscle tumor characterized by a) a significant number of cells with dense eosinophilic cytoplasm and enlarged, bizarre single/multiple ...hyperchromatic or multiple nuclei without tumor necrosis and b) poor mitotic activity. We report the case of an atypical (bizarre) leiomyoma revealed by focal fluoro-deoxyglucose (FDG) uptake during a PET-CT in a patient with relapsing abdominal and retroperitoneal leiomyosarcoma.

A panel of experts in the field of endometriosis expressed their opinions on management options in a 28-year-old patient, attempting pregnancy for 1 year, with severe cyclic pelvic pain and with ...clinical examination and imaging techniques suggestive of adenomyosis. Many questions this paradigmatic patient may pose to the clinician are addressed, and all clinical scenarios are discussed. A decision algorithm derived from this discussion is also proposed.
