BACKGROUND: Internal carotid artery stenosis (ICAS) is associated with significantly higher risk of stroke. Autonomic function can be impaired in the presence of atheroma in the carotid sinus region. Two parameters of autonomic nervous system (ANS) function e.g. heart rate variability (HRV) and baroreflex sensitivity (BRS) are respected predictors of cardiovascular prognosis. We assessed the effect of elective unilateral carotid endarterectomy (CEA) on cardiovascular autonomic functions as a major prognostic factor for cardiovascular health...

BACKGROUND: Ventilator-Associated Pneumonia (VAP) is an undesired side effect of mechanical ventilation in intensive care units (ICUs). AIM: We evaluated whether endotracheal tubes with subglottic secretion drainage (SSD) would reduce the incidence of VAP among patients undergoing mechanical ventilation in an ICU. METHODS: The analysis of medical records of patients undergoing mechanical ventilation exceeding 48 h who were hospitalised in ICUs between 2007 and 2014 led to separating two groups of patients: those in whom no subglottic drainage was applied (NSSD) (records dating from 2007-2010) and those whose treatment involved endotracheal tubes with subglottic secretion drainage (SSD) (records dating from 2011-2014)...

BACKGROUND AND AIM: The otolaryngologist often meets with fractures of the orbital floor. The most serious complication is diplopia, arising as a result of herniation of the orbital contents, with or without fixation of the inferior rectus muscle. The aim of our work was to create a mathematical model to calculate the volume of prolapsed soft tissue of the orbit in blow-out fractures, as a factor in deciding on the need for surgical treatment. PATIENTS AND METHODS: In a retrospective study (2007-2013), we evaluated 80 patients with blow-out fractures, divided into two equal groups: 40 conservatively treated and 40 surgically treated patients...

Backgroung and Aim. This work builds on our publication on the subject of creating a mathematical model for calculating the volume of proplaped soft tissue of the orbit in blow-out fractures, which aids us greatly in our choice of the most effective treatment immediately post-accident. PATIENTS AND METHODS: In this prospective study (2014 - 2016) we treated 29 patients with blow-out fractures. 18 (62%) were treated conservatively and in 11 (38%) we proceeded surgically. We decided whether surgical or non-surgical therapy was appropriate on the basis of clinical ENT, eye examination and the total volume of prolapsed orbital soft tissue...

CASE REPORT: We describe an unusual case of pelvic lymph node endometriosis with an aberrant immunophenotype mimicking metastasis of adenocarcinoma. A 37-year-old patient with a history of invasive cervical adenocarcinoma stage pT1a2 is presented. Due to insufficient loop electrosurgical excision procedure (LEEP) conization, total laparoscopic hysterectomy with pelvic lymphadenectomy was indicated. Intraoperatively, the diagnosis of deep infiltrating endometriosis of parametrial ligament and vesicouterine pouch, endometrioma of the left ovary and Allen Master's syndrome was suspected; the patient had no history or clinical symptoms of endometriosis...

BACKGROUND: Goblet cell carcinoids belong to neuroendocrine tumors, according to the WHO classification. The tumors are diagnosed based on a typical histological pattern and using neuroendocrine markers. However, some tumors do not react with these markers and yet expression of proliferative markers is high. Do these tumors belong to G1 and G2 neuroendocrine tumors? METHODS: The sample comprised nine cases of tumors of the appendix identified by immunohistological methods as goblet cell carcinoids or adenocarcinoma ex goblet cell carcinoid...

Cardiovascular (CV) disease is the primary cause of death in diabetic patients and one of the explanations may be increased arterial stiffness. Arterial stiffness assessment using pulse wave analysis, is a predictive factor of CV events. The aim of this paper is to review the current knowledge of relations between diabetes mellitus and pulse wave analysis. A MEDLINE search was performed to retrieve both original and review articles addressing the relations and influences on arterial stiffness in diabetics. Pulse wave analysis is considered as a gold standard in CV risk evaluation for patients at risk, especially diabetics...
