Prospective Randomized Study on the Use of Sentinel Node Biopsy for High-risk Cutaneous Squamous Cell Carcinomas of the Head and Neck.

Background: The use of sentinel lymph node biopsy (SLNB) for high-risk cutaneous squamous cell carcinoma (CSCC) is not yet clearly documented, especially for the head and neck area, due to its rich and cross-branching lymphatic system. We present the first prospective randomized study on the use of SLNB in high-risk CSCCs of the head and neck.

Methods: Seventy-six patients with high-risk CSCCs of the head and neck were randomly divided into two groups: A (n = 38) and B (n = 38).

The Role of Biomarkers in Lung Cancer Screening.

Aim: We aim to provide an up-to-date overview of the current evidence regarding the use of biomarkers in LCS.

Study Protocol of a Prospective, Monocentric, Single-Arm Study Investigating the Correlation of Endograft Properties with Aortic Stiffness in Abdominal Aortic Aneurysm Patients Subjected to Endovascular Aortic Repair.

The number of endovascular aortic repairs (EVARs) has surpassed the number of open surgical repairs of abdominal aortic aneurysms (AAAs) worldwide. The available commercial endoprostheses are composed of materials that are stiffer than the native aortic wall. As a consequence, the implantation of stent-graft endoprostheses during EVAR increases aortic rigidity and thus aortic stiffness, resulting in a decrease in abdominal aorta compliance.

Ablation for Single Pulmonary Nodules, Primary or Metastatic. Εndobronchial Ablation Systems or Percutaneous.

Single pulmonary nodules are a difficult to diagnose imagining artifact. Currently novel diagnostic tools such as Radial-EBUS with or not C-ARM flouroscopy, electromagnetic navigation systems, robotic bronchoscopy and cone beam-compuer tomography (CBCT) can assist in the optimal guidance of biopsy equipment. After diagnosis of lung cancer or metastatic disease as pulmonary nodule, then surgery or ablation methods as local treatment can be applied.

Immunotherapy for the elderly. Maybe the best option for lung cancer?

Lung cancer is usually diagnosed at advanced stage and systematic therapy is administered. New current diagnostic techniques such as the convex-endobronchial ultrasound, radial endobronchial ultrasound, cone beam ct, electromagnetic navigation and robotic bronchoscopy provide us with a high diagnostic yield. These techniques are minimal invasive and patients with comorbidities such as chronic obstructive pulmonary disease and heart failure can be diagnosed with minimal adverse effects.

Sotorasib after immune checkpoint inhibitor administration induces hepatotoxicity. True, false or just another adverse effect of NSCLC treatment.

Non-small cell lung cancer is still diagnosed at a late disease stage and systematic therapy is necessary. Currently we have three main treatment modalities; chemotherapy, targeted with tyrosine kinase inhibitors and immune check point inhibitors. In the recent years and based on new studies we can administer combination of chemotherapy and immunotherapy, or radiotherapy and immunotherapy.

Inhaled nintentanib, pirfenidone and macitentan for pulmonary fibrosis: a laboratory experiment.

Idiopathic pulmonary fibrosis is a rare disease with few efficient drugs in the market. The consequences of this disease are mainly respiratory failure and pulmonary hypertension. In our experiment we used the drugs pirfenidone, nintetanib and macitentan.

Epithelial Ovarian Cancer: A Five Year Review.

Ovarian cancer is a malignant disease that affects thousands of patients every year. Currently, we use surgical techniques for early-stage cancer and chemotherapy treatment combinations for advanced stage cancer. Several novel therapies are currently being investigated, with gene therapy and stem cell therapy being the corner stone of this investigation.

Excessive supraventricular ectopic activity and future onset of atrial fibrillation in patients with cryptogenic stroke.

Objectives: Although evidence has shown the association of excessive supraventricular ectopic activity (ESVEA) with future development of atrial fibrillation (AF), this relationship is not yet fully understood. This study examines whether ESVEA can predict the future onset of AF, in patients presenting with cryptogenic stroke.

Materials And Methods: A retrospective cohort of 124 non-AF, consecutive patients, hospitalized for cryptogenic stroke between 2014 and 2015, was retrieved.

The Gestational Effects of Maternal Bone Marker Molecules on Fetal Growth, Metabolism and Long-Term Metabolic Health: A Systematic Review.

Fetal exposure in adverse environmental factors during intrauterine life can lead to various biological adjustments, affecting not only in utero development of the conceptus, but also its later metabolic and endocrine wellbeing. During human gestation, maternal bone turnover increases, as reflected by molecules involved in bone metabolism, such as vitamin D, osteocalcin, sclerostin, sRANKL, and osteoprotegerin; however, recent studies support their emerging role in endocrine functions and glucose homeostasis regulation. Herein, we sought to systematically review current knowledge on the effects of aforementioned maternal bone biomarkers during pregnancy on fetal intrauterine growth and metabolism, neonatal anthropometric measures at birth, as well as on future endocrine and metabolic wellbeing of the offspring.

Evaluation of a Novel Αb Εxterno MicroShunt for the Treatment of Glaucoma.

The surgical management of glaucoma has been revolutionized by the introduction of minimally invasive glaucoma surgery (MIGS). The various MIGS options aim to meaningfully lower intraocular pressure with a better safety profile than traditional glaucoma surgery. The key clinical attributes and the emerging potential of an ab externo MicroShunt (PreserFlo™) are reviewed in the context of published evidence and clinical experience.

Methods: Retrospective, observational cohort study. We compared 134 eyes treated with the IntraLase 60 kHz, 112 eyes treated with the Femto LDV Z6, 206 eyes treated with the FS200, and 98 eyes treated with the Hansatome zero compression microkeratome.

Modification Tadalafil and Macitentan tablets to aerosol.

Introduction: Aerosolised drugs have been approved for several diseases such as cystic fibrosis and diabetes. Moreover; there are already drugs for pulmonary hypertension in aerosol form already on the market.

Materials And Methods: Two drugs for pulmonary hypertension (Tadalafil and Macitentan) were milled and transformed from tablets to powder.

The Gestational Effects of Maternal Appetite Axis Molecules on Fetal Growth, Metabolism and Long-Term Metabolic Health: A Systematic Review.

Increased maternal food intake is considered a normal pregnancy adjustment. However, the overavailability of nutrients may lead to dysregulated fetal development and increased adiposity, with long-lasting effects on offspring in later life. Several gut-hormone molecules regulate maternal appetite, with both their orexigenic and anorectic effects being in a state of sensitive equilibrium.

The emotional burden of the SARS-CoV-2 pandemic on medical students in Greece.

Medical students were found to be a vulnerable population, facing many challenges with the temporary suspension of clinical activities, as well as their confrontation with violent changes in their chosen profession. The purpose of the present study is to record and detect possible signs of emotional burden on the psychological profile of northern Greek medical students in the second wave of the European pandemic at the hitherto culmination point.

Emerging Treatment Modalities for Neovascular Age-Related Macular Degeneration: A Systematic Overview.

Introduction: Neovascular age-related macular degeneration (nAMD) represents a leading cause of irreversible visual loss affecting the quality of life of millions of elderly patients worldwide. Although the introduction of intravitreal injections with anti-vascular endothelial growth factors (anti-VEGF) agents has revolutionized the management of nAMD, their effectiveness and ultimate success are limited by several therapeutic challenges. Consequently, real-world efficacy appears significantly inferior to that reported by randomized controlled trials.

A new look at the safety and tolerability of prostaglandin analogue eyedrops in glaucoma and ocular hypertension.

Introduction: In the last 25 years, topical prostaglandin analogues (PGAs) have emerged to become first line and first choice therapeutic options in the management of glaucoma and ocular hypertension (OHT). Although the short-term efficacy and safety of PGAs has been extensively investigated, less is known about their long term safety and tolerability. This gap in current knowledge is clinically relevant, because treatment-related adverse events and long-term tolerability issues are key determinants of the overall success of long-term therapy and the final outcome of a lifelong, symptomless disease like glaucoma.
