A simple technique for morphological measurement of cerebral arterial circle variations using public domain software (Osiris)

This article describes a straightforward method to measure the dimensions and identify morphological variations in the cerebral arterial circle using the general-purpose software program Osiris. This user-friendly and portable program displays, manipulates, and analyzes medical digital images, and it has the capability to determine morphometric properties of selected blood vessels (or other anatomical structures) in humans and animals. To ascertain morphometric variations in the cerebral arterial circle, 132 brains of recently deceased fetuses, infants, and adults were dissected. The dissection procedure was first digitized, and then the dimensions were measured with Osiris software. Measurements of each vessel's length and external diameters were used to identify and classify morphological variations in the cerebral arterial circle. The most commonly observed anatomical variations were uni- and bilateral hypoplasia of the posterior communicating artery. This study demonstrates that public domain software can be used to measure and classify cerebral arterial circle vessels. This method could be extended to examine other anatomical regions or to study other animals. Additionally, knowledge of variations within the circle could be applied clinically to enhance diagnostic and treatment specificity

Supplemental Information 2: Forrest plots for the origins of the medial circumflex femoral artery

Background and Objectives. The medial circumflex femoral artery (MCFA) is a common branch of the deep femoral artery (DFA) responsible for supplying the femoral head and the greater trochanteric fossa. The prevalence rates of MCFA origin, its branching patterns and its distance to the mid-inguinal point (MIP) vary significantly throughout the literature. The aim of this study was to determine the true prevalence of these characteristics and to study their associated anatomical and clinical relevance. Methods. A search of the major electronic databases Pubmed, EMBASE, Scopus, ScienceDirect, Web of Science, SciELO, BIOSIS, and CNKI was performed to identify all articles reporting data on the origin of the MCFA, its branching patterns and its distance to the MIP. No data or language restriction was set. Additionally, an extensive search of the references of all relevant articles was performed. All data on origin, branching and distance to MIP was extracted and pooled into a meta-analysis using MetaXL v2.0. Results. A total of 38 (36 cadaveric and 2 imaging) studies (n = 4,351 lower limbs) were included into the meta-analysis. The pooled prevalence of the MCFA originating from the DFA was 64.6% (95% CI [58.0–71.5]), while the pooled prevalence of the MCFA originating from the CFA was 32.2% (95% CI [25.9–39.1]). The CFA-derived MCFA was found to originate as a single branch in 81.1% (95% CI [70.1–91.7]) of cases with a mean pooled distance of 50.14 mm (95% CI [42.50–57.78]) from the MIP. Conclusion. The MCFA’s variability must be taken into account by surgeons, especially during orthopedic interventions in the region of the hip to prevent iatrogenic injury to the circulation of the femoral head. Based on our analysis, we present a new proposed classification system for origin of the MCFA

Assessment of chronic disease acceptance based on the example of patients with chronic obstructive pulmonary disease

Introduction. Chronic obstructive pulmonary disease is one of the most common diseases in the world. It is one of the most important social problems causing high mortality. The changes occurring in the lungs are characterized by not fully reversible airflow limitation through air passages. Treatment of patients with chronic obstructive pulmonary disease consists in the prevention of the disease progression and reduction of the factors that cause the disease and its exacerbation. The quality of life in patients with chronic obstructive pulmonary disease is significantly affected by pulmonary rehabilitation, which is part of the therapy. Rehabilitation includes all measures aimed at improving the physical, mental and social health of the patient. Aim. The aim of the study is to assess the level of acceptance of chronic disease based on the example of patients with chronic obstructive pulmonary disease and to study the impact of factors forming a certain level of the disease acceptance. Material and Methods. The study was conducted at the Provincial Hospital in Plock. The study group consisted of 100 patients in the Department of Pulmonary Diseases and Tuberculosis. The research was carried out by means of an estimating method and a diagnostic survey. The Disease Acceptance Scale as well as the survey questionnaire were used as the research tools. Results. The studies have shown that patients accept the disease at the secondary level. The disease acceptance assessment are affected by health, psychological and social factors. Conclusions. 1. The acceptance level of chronic obstructive pulmonary disease does not depend significantly on gender, age, education, marital status and the way of residing. 2. The acceptance of chronic obstructive pulmonary disease depends significantly on the place of one’s residence. Patients residing in the city exhibit a higher level of acceptance of the disease compared with those living in the countryside. 3. The acceptance of chronic obstructive pulmonary disease depends significantly on comorbidities. Patients with concomitant diseases present a lower level of acceptance of the disease than patients without other diseases

Venous configurations of the anterior cubital region

Venous configurations of the anterior cubital region were examined on the sample of 203 country children. The occurence of vessel connections of Y -type was found in 91,9%. The variant had 10 modificatins (a-j). Modification of j-type which was observed in boys was the most ramified one. The relation between the kind of the work and the kind of the vessel configuration has been suggested

BODY BUILD OF POLYTECHNIC PUPILS AND TRACTOR DRIVERS

BODY BUILD OF POLYTECHNIC PUPILS AND TRACTOR DRIVERS. The weight-and-height Rohrer’s index was calculated for 102 pupils of the Polytechnic for Agiculture Mechanization and 160 tractor drivers employed in state-owned farms.* It was found out that with age the pupils developed a tendency towards an athletic body build, whereas the tractor drivers with the passage of years of work a tendency towards a pyknic body build

Skeletopy of the brachiocephalic trunk and the common carotid arteries in human fetuses

By means of anatomical and radiological methods and with help of the Computer Digital Image Analysis System the brachiocephalic trunk and the common carotid arteries in relation to the vertebral column were studied in 60 human fetuses. The vessels were found to be between the upper borders: of the third thoracic vertebra and the first cervical vertebra (Th3s-C1s). In the 6th month of the ontogenetic development the vessels descended by one vertebra and established their location in the next prenatal compartment (8-9) between the lower borders: of these same vertebra (Th 3i - C 1i ). We have counted the skeletopic age correlation coefficients of these vessels andfound the diminuation of their values. Sexual skeletopic dimorphisms have not been observed. These investigations have clinical implications
