1Intentional ingestions of foreign objects among prisoners: A review显示文摘The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations.David C Evans Thomas R Wojda Christian D Jones Andrew J Otey Stanislaw P Stawicki 2015World Journal of Gastrointestinal Endoscopy2015,7,3:10
2Liver transplantation for metastatic neuroendocrine tumor: A case report and review of the literature显示文摘Neuroendocrine tumors are divided into gastrointestinal carcinoids and pancreatic neuroendocrine tumors. The WHO has updated the classification of these lesions and has abandoned the term 'carcinoid'. Both types of tumors are divided into functional and non-functional tumors. They are characterized by slow growth and frequent metastasis to the liver and may be limited to the liver for long periods. The therapeutic approach to hepatic metastases should consider the number and distribution of the liver metastases as well as the severity of symptoms related to hormone production and tumor bulk. Surgery is generally considered as the first line therapy. In patients with unresectable liver metastases,alternative treatments are dependent on the type and the growth rate. Initial treatments consist of long acting somatostatin analogs and/or interferon. Streptozocinbased chemotherapy is usually reserved for symptomatic patients with rapidly advancing disease, but generally the therapy is poorly tolerated and its effects are short-lived.Locoregional therapy directed such as hepatic-artery embolization and chemoembolization, radiofrequency thermal ablation and cryosurgery, is often used instead of systemic therapy, if the disease is limited to the liver.However, liver transplantation should be considered in patients with neuroendocrine metastases to the liver that are not accessible to curative or cytoreductive surgery and if medical or locoregional treatment has failed and if there are life threatening hormonal symptoms. We report a case of liver transplantation for metastatic neuroendocrine tumor of unknown primary source and provide a detailed review of the world literature on this controversial topic.Wojciech C Blonski K Rajender Reddy Abraham Shaked Evan Siegelman David C Metz 2005World Journal of Gastroenterology2005,11,48:5

16Two-color multiphoton in vivo imaging with a femtosecond diamond Raman laser显示文摘Two-color multiphoton microscopy through wavelength mixing of synchronized lasers has been shown to increase the spectral window of excitable fluorophores without the need for wavelength tuning.However,most currently available dual output laser sources rely on the costly and complicated optical parametric generation approach.In this report,we detail a relatively simple and low cost diamond Raman laser pumped by a ytterbium fiber amplifier emitting at 1055 nm,which generates a first Stokes emission centered at 1240 nm with a pulse width of 100 fs.The two excitation wavelengths of 1055 and 1240 nm,along with the effective two-color excitation wavelength of 1140 nm,provide an almost complete coverage of fluorophores excitable within the range of 1000–1300 nm.When compared with 1055 nm excitation,two-color excitation at 1140 nm offers a 90%increase in signal for many far-red emitting fluorescent proteins(for example,tdKatushka2).We demonstrate multicolor imaging of tdKatushka2 and Hoechst 33342 via simultaneous two-color two-photon,and two-color three-photon microscopy in engineered 3D multicellular spheroids.We further discuss potential benefits and applications for two-color three-photon excitation.In addition,we show that this laser system is capable of in vivo imaging in mouse cortex to nearly 1 mm in depth with two-color excitation.Evan P Perillo Jeremy W Jarrett Yen-Liang Liu Ahmed Hassan Daniel C Fernée John R Goldak Andrei Bonteanu David J Spence Hsin-Chih Yeh Andrew K Dunn 2017Light(Science & Applications)2017,6,1:1
