Angiogenesis and eosinophilia in the nasal mucosa of patients with different clinical phenotypes of chronic rhinosinusitis.

Introduction: Dense inflammatory cell infiltration and vascularization of the nasal mucosa are histological characteristics of chronic rhinosinusitis (CRS). We aimed to evaluate the association between eosinophilia and vascularization in the stroma of mucosal layer/nasal polyps (NP) and clinical parameters in patients with different phenotypes of CRS.

Methodology: This cross-sectional study involved 33 patients who had CRS with NP without aspirin sensitivity (CRSwNP), 20 NP patients as a part of aspirin-exacerbated respiratory disease (AERD), and 10 patients who had CRS without NP (CRSsNP), selected for surgery.

Retinal microvascular complexity as a putative biomarker of biological age: a pilot study.

Physiological changes associated with aging increase the risk for the development of age-related diseases. This increase is non-specific to the type of age-related disease, although each disease develops through a unique pathophysiologic mechanism. People who age at a faster rate develop age-related diseases earlier in their life.

TREND database: Retinal images of healthy young subjects visualized by a portable digital non-mydriatic fundus camera.

Topological characterization of the Retinal microvascular nEtwork visualized by portable fuNDus camera (TREND) is a database comprising of 72 color digital retinal images collected from the students of the Faculty of Medicine at the University of Montenegro, in the period from February 18th to March 11th 2020. The database also includes binarized images of manually segmented microvascular networks associated with each raw image. The participant demographic characteristics, health status, and social habits information such as age, sex, body mass index, smoking history, alcohol use, as well as previous medical history was collected.

Fractal characterization of retinal microvascular network morphology during diabetic retinopathy progression.

Objective: The study aimed to characterize morphological changes of the retinal microvascular network during the progression of diabetic retinopathy.

Methods: Publicly available retinal images captured by a digital fundus camera from DIARETDB1 and STARE databases were used. The retinal microvessels were segmented using the automatic method, and vascular network morphology was analyzed by fractal parametrization such as box-counting dimension, lacunarity, and multifractals.

The pterygopalatine fossa: morphometric CT study with clinical implications.

Purpose: The pterygopalatine fossa is a deep viscerocranial space containing the maxillary artery and nerve, the pterygopalatine ganglion, and the nerve of the pterygoid canal (vidian nerve). The endoscopic approach to this area relies on adequate preoperative imaging, such as computed tomography (CT). The aim was to determine the morphometric characteristics of the pterygopalatine fossa and its communications, including several previously unpublished measurements.

Superficial palmar branch of the radial artery: A study of occurrence and diameter.

The superficial palmar branch (SPB) of the radial artery (RA) is an important blood vessel in plastic surgery procedures of the hand. It is used as the axial artery in a free flap used for finger reconstruction. The occurrence of this arterial branch is variable, as well as its diameter and course.

Duplication of the middle cerebral artery in a neonate: case report.

The middle cerebral artery, a terminal branch of the internal carotid artery, participates greatly in the blood supply of the cerebral cortex and basal nuclei. The aim of this paper is to present a case of middle cerebral artery duplication in a 3-day-old neonate. A brief literature overview in this paper serves to summarize the research on the middle cerebral artery duplication.

Manually segmented vascular networks from images of retina with proliferative diabetic and hypertensive retinopathy.

In this article we present a data set that contains 37 image files obtained by manual vessel segmentation of raw retinal images from Structured Analysis of the Retina (STARE) database ("The STARE Project", 2018) [1]. Our expert segmented 8 images that are associated with the single diagnosis of hypertensive retinopathy and 9 images with the single diagnosis of proliferative diabetic retinopathy (Popovic et al., 2018) [2].

Asymmetry of the greater cornua of the hyoid bone and the superior thyroid cornua: a case report.

The hyoid bone consists of a body and two pairs of processes: the greater cornua (GC) and the lesser cornua. The GC is connected to the superior thyroid cornu (STC) by the lateral thyrohyoid ligament. The GC and the STC share a common embryological origin from the third pharyngeal arch.

Clinical significance of understanding lateral and medial circumflex femoral artery origin variability.

The common femoral artery (CFA) divides into the superficial femoral artery (SFA) and deep femoral artery (DFA). The lateral circumflex femoral artery (LCFA) and medial circumflex femoral artery (MCFA) are most often branches of the DFA, although a large number of different variations in their origin has been described. We performed microdissection on both lower limbs of 30 fetuses, gestational age from 7 to 10 lunar months.

Fractal dimension and lacunarity analysis of retinal microvascular morphology in hypertension and diabetes.

Hypertension and diabetes mellitus represent modifiable risk factors for vascular disease. They cause microvascular remodeling, and ultimately result in end-organ damage. Therefore, development of methods for noninvasive quantification of the effects of hypertension and diabetes mellitus on microvasculature is of paramount importance.

Complications of Laparoscopic Cholecystectomy: Our Experience from a Retrospective Analysis.

Aim: The aim of this study was to evaluate the intraoperative and postoperative complications of laparoscopic cholecystectomy, as well as the frequency of conversions.

Material And Methods: Medical records of 740 patients who had laparoscopic cholecystectomy were analysed retrospectively. We evaluated patients for the presence of potential risk factors that could predict the development of complications such as age, gender, body mass index, white blood cell count and C-reactive protein (CRP), gallbladder ultrasonographic findings, and pathohistological analysis of removed gallbladders.

Restricting sports activity in reducing the rate of varicocele and related infertility parameters in athletes.

Introduction: The aim of this study is to test the hypothesis that the cessation of sports training in young athletes reduces the prevalence of varicocele.

Material And Methods: 1,013 young males were divided into three age-matched groups based on their sport activity. The first group consisted of 305 athletically active boys in basketball, volleyball, handball, or football; the second of 44 active water-polo players, and the third of 664 sport-inactive controls.

Morphometric analysis of the fascicular organisation of the optic nerve.

Background/aim: The optic nerve is anatomically observed in four segments: intrabulbar, orbital, canalicular, and cranial. According to the literature, the surface of the transversal cut of the nerve is different through it. The aim of this study was to evaluate the fascicular organisation of the optic nerve, throughout its three segments fromthe eye.

Traumatic acute myocardial ischaemia involving two vessels.

Myocardial infarctions caused by coronary artery injury after blunt chest trauma is a fatal, but rare occurrence. In the case reported on here, a fatally injured 69-year-old male driver sustained such trauma in a frontal car collision. The autopsy found a laceration of the left anterior descending artery as well as a subsequent subepicardial haematoma surrounding this artery and the circumflex artery.

The bilateral anatomical variation of the sural nerve and a review of relevant literature.

The sural nerve is a sensory nerve, usually formed in the distal part of the leg by the union of the lateral sural cutaneous nerve or the communicating fibular branch with the medial sural cutaneous nerve. The aim of this paper is to present a case of a variant formation of the sural nerve and a review of the literature related to this case. During the dissection of an adult male cadaver, the medial sural cutaneous nerve and communicating fibular branch, after respectively deriving from the tibial and common fibular nerve, were noticed to continue their course without any formation of a unique nerve trunk on the posterior side of both lower limbs.

Biohumoral and endocrine parameters in assessment of surgical trauma in open and laparoscopic cholecystectomy.
