Fecalomas represent firm organized form of impacted feces. They are commonly seen in sigmoid colon. We report a case of large fecaloma in young adult female with chronic constipation, which was managed conservatively. 相似文献

Venous aneurysms are one of the rare causes of neck swellings. Among neck veins, external jugular vein aneurysms are uncommon. We present a case of a woman who presented with a nontender compressible swelling in the left lower neck region, which initially thought to be hemangioma, was later found to be external jugular vein aneurysm on Doppler ultrasound and CT angiography. 相似文献

Imidacloprid-induced hormesis in the form of stimulated reproduction has previously been reported in green peach aphid, Myzus persicae. Changes in gene expression accompanying this hormetic response have not been previously investigated. In this study, expression of stress response (Hsp60), dispersal (OSD, TOL and ANT), and developmental (FPPS I) genes were examined for two generations during imidacloprid-induced reproductive stimulation in M. persicae. Global DNA methylation was also measured to test the hypothesis that changes in gene expression are heritable. At hormetic concentrations, down-regulation of Hsp60 was followed by up-regulation of this gene in the subsequent generation. Likewise, expression of dispersal-related genes and FPPS I varied with concentration, life stage, and generation. These results indicate that reproductive hormesis in M. persicae is accompanied by a complex transgenerational pattern of up- and down-regulation of genes that likely reflects trade-offs in gene expression and related physiological processes during the phenotypic dose-response. Moreover, DNA methylation in second generation M. persicae occurred at higher doses than in first-generation aphids, suggesting that heritable adaptability to low doses of the stressor might have occurred. 相似文献

We present a case of Takotsubo Cardiomyopathy (TC) which is a non ischemic cardiomyopathy. It is stress related and also known as broken heart syndrome. The patient presented to our emergency department with symptoms of chest pain and breathlessness. The patient was diagnosed as acute coronary syndrome and various tests including ECG, Screening ECHO, Coronary CT and Cardiac Magnetic Resonance (CMR) were done before arriving at the diagnosis of TC. Currently CMR is the modality of choice as it detects the wall motion abnormalities (WMA), presence of wall edema and late gadolinium enhancement (LGE) characteristics can be well appreciated. No intervention was done and the case was managed medically. 相似文献
