The hypothalamus is a small but important area of the brain formed by various nucleus and nervous fibers. Through its neuronal connections, it is involved in many complex functions of the organism such as vegetative system control, homeostasis of the organism, thermoregulation, and also in adjusting the emotional behavior. The hypothalamus is involved in different daily activities like eating or drinking, in the control of the body's temperature and energy maintenance, and in the process of memorizing. It also modulates the endocrine system through its connections with the pituitary gland. Precise anatomical description along with a correct characterization of the component structures is essential for understanding its functions.
Various biomarkers were used for Cancer Stem Cells (CSCs) identification in colon cancer patients: CD133, EpCAM (epithelial intracellular adhesion molecule)/CD326, CD44, CD24, or CD166 [1]. Cancer stem cells (CSCs) involvement in tumor mass formation, in cancer progression, in recurrence and, most important, in resistance to chemotherapy is acknowledg, likewise their major role in carcinogenesis and metastatic processes. CD133 or prominin-1 is a glycoprotein of 120 kDa encoded by the gene PROM1 positioned on the short arm of chromosome 4 [2]. Studies conducted so far in colon cancer found that high CD133 expression at tumoral level correlates with advanced stages of the disease and poor overall survival (OS) [3-5], supporting its use as a negative prognostic factor. The aim of this study was (1) to analyze CD133 expression in colon cancer samples, (2) to evaluate if CD133 expression
Colon cancer incidence is increasing in young people. Even if, so far, colon cancer had a maximum incidence in the sixth and seventh decades of life, lately its incidence in people age 50 and younger is increasing. Thus, colon cancer still represents a major health problem despite constant research made in the field. Early detection of colon cancer is mandatory for an appropriate treatment of the disease and to attain increased overall survival. Even if various stem cell markers have been studied in order to evaluate their prognostic value in colon cancer cases, results in literature are heterogeneous, and no clear consensus has been drafted so far. This paper aims to review the most important stem cell markers identified in colon cancer and to establish their role in both cancer diagnosis and progression.
Desmoid tumors (DT) are rare non-metastatic neoplasms that occur through myofibroblast proliferation in musculoaponeurotic or fascial structures of the body, being commonly diagnosed in young women during pregnancy or in the post-partum period. We present the case of a 38-year-old woman, who recently gave birth, manifesting non-specific abdominal symptoms. Computed tomography indicated the presence of a solitary tumor arising from the intestinal wall or from the mesentery. Surgery confirmed the diagnosis, revealing a tumor that was localized at the level of the jejunal mesentery, having about 7 cm in diameter, in tight contact with the duodenum and the mesenteric vessels. ‘‘En bloc’’ resection of the tumor was performed, together with the involved enteral loops followed by end-to-end anastomosis of the jejunum. Histopathological examination of the surgical specimen sustained the diagnosis of desmoid tumor.
Aim: Parathyroid carcinoma (PC) is a rare endocrine malignancy that represents 0.005% of all malignant tumors. Associated PC and differentiated thyroid carcinoma (DTC) is an exceptionally rare condition, and the preoperative diagnostics and proper treatment are challenging. Almost all PCs and the majority of DTCs are diagnosed postoperatively, making correct surgical treatment questionable. Specific guidelines for parathyroid and thyroid carcinomas association treatment are lacking. The purposes of our study were to identify the association between parathyroid and thyroid carcinomas, to analyze the available published data, and to evaluate the possible relationship between preoperative diagnostic and surgical decision-making, and outcome-related issues. Material and methods: We performed a literature review of several databases from the earliest records to March 2022, using controlled vocabulary and keywords to search for records on the topic of PC and WDTC pathological association. The reference lists from the initially identified articles were analyzed to obtain more references. Results: We identified 25 cases of PC and DTC association, 14 more than the latest review from 2021. The mean age of patients was 55, with a female to male ratio of about 3:1. Exposure to external radiation was identified in only one patient, although it is considered a risk factor the development of both PC and DTC. The preoperative suspicion of PC was stated by the authors in only 25% of cases, but suspicion based on clinical, laboratory, ultrasound (US), and fine needle aspiration (FNA) criteria could have been justified in more than 50% of them. With neck ultrasound, 40% of patients presented suspicious features both for PC and thyroid carcinoma. Intra-operatory descriptions of the lesions revealed the highest suspicion (83.3%) of PC, but en bloc resection was recommended and probably performed in only about 50% of the cases. Histopathological examinations of the thyroid revealed different forms of papillary thyroid carcinoma (PTC) in most cases. Postoperative normocalcemia was achieved in 72% of patients, but follow-up data was missing in about 25% of cases. Conclusion: Associated PC and DTC is an exceptionally rare condition, and the preoperative diagnostic and treatment of the patients is a challenge. However, in most cases pre- and intraoperative suspicious features are present for identification by a highly specialized multidisciplinary endocrine team, who can thus perform the optimal treatment to achieve curability.
Passionate about surgery, she completed her residency training through valuable professional fellowship programs in the field of hepato-bilio-pancreatic surgery and minimally invasive procedures in France (Centre Hepato-Biliare Paul Brousse, Paris, IRCAD Laparoscopic Training Center, Strasbourg) and the Netherlands (the Netherlands Cancer Institute-NKI, Amsterdam). This scientific activity has resulted in the publication of seven anatomy and surgery chapters and 11 scientific papers. Contents
