Current and emerging bone resorption inhibitors for the treatment of osteoporosis.

Introduction: Osteoporosis is a metabolic skeletal disease characterized by low bone mass and strength, and increased risk for fragility fractures. It is a major health issue in aging populations, due to fracture-associated increased disability and mortality. Antiresorptive treatments are first line choices in most of the cases.

Pituitary Dysfunction as a Cause of Cardiovascular Disease.

The hypothalamic-pituitary axis is responsible for the neuroendocrine control of several organ systems. The anterior pituitary directly affects the functions of the thyroid gland, the adrenal glands, and gonads, and regulates growth and milk production. The posterior hypophysis, through nerve connections with the hypothalamic nuclei, releases vasopressin and oxytocin responsible for water balance and social bonding, sexual reproduction and childbirth, respectively.

The importance of postoperative analgesia after major thoracic surgery interventions, protocols, applications, and the following evaluation of the patient's quality of life.

Objectives: Major thoracic surgery procedures constitute a standard method of diagnosis and/or therapy against lung, mediastinal cancer and other non-malignant manifestations of the respiratory system. Such patients' recovery and rehabilitation depend directly from the applied postoperative analgesia, with purpose to determine an optimum and long-term quality of life.

Background: Our database consists of 300 individuals, submitted to major thoracic surgery procedure during a 2 - year period of time (between December 2016 and December 2018) at the "Thoracic Surgery Department" of "Theageneio" Cancer Hospital, Thessaloniki.

Objective: To evaluate the association of TSH and FT4 with incident fractures in euthyroid individuals.

Design: Individual participant data analysis.

A patient with situs inversus totalis and lung cancer-a rare combination.

Situs inversus totalis (SIT) is a rare clinical entity which is characterized by a complete reverse anatomy of the thoracic cage and abdomen. There are a few reports of patients with SIT and lung cancer. The number of the cases that have been treated surgically is also very small.

Percutaneous tracheostomy-beware of the thyroidea-ima artery.

Percutaneous tracheostomy is a minimally invasive operation performed in patients, in order to provide an air passage through the windpipe. A rare cause of severe bleeding during such operation is the injury of the thyroidea-ima artery. This case report presents a patient with hemorrhage after thyroidea-ima injury during percutaneous dilatational tracheostomy.

Successful surgical treatment of a complicated esophageal perforation, by use of primary closure and lung parenchyma reinforcement.

Esophageal perforation (EP) is a medical condition which demands urgent confrontation with significant complications. The cause of the perforation may be common, spontaneous or iatrogenic, with conservative or surgical therapeutic strategy, which is needed in the majority of incidents, depending on the characteristics of the lesion. We report a case of a 68-year-old man, with the existence of an ulcerative lesion 31 cm approximately from the dental barrier, and a coexistent stenosis, diagnosed through esophagogastroduodenoscopy, which evolved to an extensive purulent necrotic mediastinitis, diagnosed through a thorax CT scan after the patient began to complain of asphyxiation during eating.

Background: The purpose of this study is to review the anatomic characteristics of internal thoracic artery (ITA) and its branches, in order to pursue the extension of its utilization and avoid intraoperative and postoperative complications.

Methods: The study was carried out on anterior chest walls obtained during routine autopsies of 50 specimens (30 male, 20 female). Macroscopic and microscopic dissection was performed and the following were studied: origin, length and termination of ITA, size and distance from the sternum, and types of branches.

Double primary non-small cell lung cancer with synchronous small cell lung cancer N2 nodes: a case report.

Synchronous multiple primary lung cancer (SMPLC) is rare and very hard to distinguish from metastatic disease. Recent studies indicate the presence of this entity in the lung, with no mention to the involvement of the mediastinum. An extremely rare case of a 68-year-old male with double primary non-small cell lung cancer (NSCLC) in the left upper lobe and N2 positive nodes for small cell lung cancer (SCLC) is presented.

Thyrostimulin Regulates Osteoblastic Bone Formation During Early Skeletal Development.

The ancestral glycoprotein hormone thyrostimulin is a heterodimer of unique glycoprotein hormone subunit alpha (GPA)2 and glycoprotein hormone subunit beta (GPB)5 subunits with high affinity for the TSH receptor. Transgenic overexpression of GPB5 in mice results in cranial abnormalities, but the role of thyrostimulin in bone remains unknown. We hypothesized that thyrostimulin exerts paracrine actions in bone and determined: 1) GPA2 and GPB5 expression in osteoblasts and osteoclasts, 2) the skeletal consequences of thyrostimulin deficiency in GPB5 knockout (KO) mice, and 3) osteoblast and osteoclast responses to thyrostimulin treatment.
