A systematic review of English and non-English articles using OVID MEDLINE (1980-2014) was performed to evaluate the potential value of prophylactic ligation of the thoracic duct in preventing chylous leakage after oesophagectomy for cancer. Search terms included [Oesophagectomy OR esophagectomy] AND [chylothorax] AND [thoracic duct ligation]. Only those papers that directly compared the incidence of chylothorax in patients who underwent prophylactic ligation [ligation group (LG)] with that in those who had conservative treatment were selected [preservation group (PG)]; all the articles presenting original data and supplying sufficient information on the chylothorax rate after oesophagectomy were included. Independent extraction of articles was performed by two authors using predefined data fields, including study quality indicators. The PRISMA guidelines were carefully adhered to. A total of 5254 subjects were included in the 7 clinical studies examined into the current meta-analysis. Of these, 2179 patients underwent prophylactic ligature of the thoracic duct (LG group) and 3075 had preservation of the thoracic duct (PG group). A significant difference in terms of chylothorax rate [odd ratios (ORs) 0.47 in favour of LG, 95% confidence interval (CI) 0.27-0.80] was noted between the LG group and the PG group. According to our meta-analysis and taking into account-specific caveats, prophylactic ligation of the thoracic duct could be considered as an effective preventative measure to reduce the incidence of postoperative chylothorax.
Over the last 50 years, the incidence of human thyroid cancer disease has seen a significative increment. This comes along with an even higher increment of surgery, since, according to the international guidelines, patients are sometimes addressed to surgery also when the fine needle aspiration gives undetermined cytological diagnosis. As a matter of fact, only 30% of the thyroid glands removed for diagnostic purpose have a post surgical histological report of malignancy: this implies that about 70% of the patients have suffered an unnecessary thyroid removal. Here we show that Raman spectroscopy investigation of thyroid tissues provides reliable cancer diagnosis. Healthy tissues are consistently distinguished from cancerous ones with an accuracy of ∼ 90%, and the three cancer typology with highest incidence are clearly identified. More importantly, Raman investigation has evidenced alterations suggesting an early stage of transition of adenoma tissues into cancerous ones. These results suggest that Raman spectroscopy may overcome the limits of current diagnostic tools.
The electronic nose (e-nose) is a promising technology as a useful addition to the currently available modalities to achieve lung cancer diagnosis. The e-nose can assess the volatile organic compounds detected in the breath and derived from the cellular metabolism. Volatile organic compounds can be analyzed to identify the individual chemical elements as well as their pattern of expression to reproduce a sensorial combination similar to a fingerprint (breathprint). The e-nose can be used alone, mimicking the combinatorial selectivity of the human olfactory system, or as part of a multisensorial platform. This review analyzes the progress made by investigators interested in this technology as well as the perspectives for its future utilization.
We describe a 12-year-old white girl with granuloma annulare localized to both ankles since she was five, necrobiosis lipoidica in the left pretibial region since she was ten, and a recent history of weakness, migraine, and weight loss. After initial evaluation, high fasting blood glucose levels and high hemoglobin A1c were found. The family history for non-insulin-dependent diabetes was suggestive of maturity-onset diabetes of the young. Coexistence of necrobiosis lipoidica and granuloma annulare, together with a family history of non-insulin-dependent diabetes, the age of onset, and the absence of ketosis, are specific features making possible, a clinical diagnosis. Genetic confirmation may not be so easily accessible or necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
