Echinococcus granulosus, first reported by Goeze in 1782, is the causative parasite of cystic echinococcosis (hydatidosis) especially for countries that are endemic areas. Since the 1970s, the incidence of echinococcosis in Greece has been very high. Nevertheless, with the implementation of special prevention measures in the 1980s, a large reduction in the incidence of hydatidosis meant that it reached European levels. Therefore, we analyzed the demographics, multiple organ localizations of the parasite, diagnosis, and conservative and optimal surgical treatment over a total period of 39 years, especially for pulmonary and hepatic echinococcosis in children. The higher incidence of pulmonary echinococcosis compared with other localizations, male predominance, wide range of age, and various cystic sizes were some of the main demographics. Because cystic echinococcosis remains a main public health problem, we advocate a meticulous clinical investigation and treatment methodology to bridge the gap between knowledge and awareness of this important disease.
Background Double adenomas (DA) represents a distinct clinical entity of primary hyperparathyroidism (PHPT). DA may follow various embryologic distribution patterns and could be supernumerary and/or ectopic. Case presentation We describe the first case of PHPT which comes as a result of double ipsilateral adenoma, of which one was both ectopic and supernumerary. A 45 year-old Greek male patient with diagnosed PHPT due to a single lower right parathyroid adenoma was admitted to our department for surgical treatment. The preoperative tests (neck US, Sestamibi scan) were conclusive for single gland disease. The patient underwent focused parathyroidectomy. The frozen section revealed a parathyroid adenoma with a slight possibility for parathyroid carcinoma. Ten minutes after the excision, intact PTH (iPTH) dropped >50% related to preoperative values and was within normal range. Right hemithyroidectomy with additional ipsilateral central neck dissection was performed, because of the possibility for parathyroid carcinoma. The final pathology report showed that the first excised tissue proved to be a parathyroid adenoma, while a second subcapsular one and a normal right upper parathyroid gland were also found. Conclusions Preoperative localization of DA using routine imaging tests and the utility of intraoperative parathyroid hormone assay are still unreliable in detecting multiple adenomas. Furthermore, a slight possibility of a second and simultaneously supernumerary and ectopic adenoma maybe present. Therefore, it would be advisable to establish the use of more advanced imaging tests (such as 4D-CT, 4D-MRI) or other diagnostic tools when DA are suspected.
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.
