A morphometric study of the celiac trunk and review of the literature.

The anatomy of the celiac trunk and its branches was examined in 77 adult human cadavers of Caucasian (Hellenic) origin. The celiac trunk followed the normal pattern, namely trifurcation to the common hepatic, splenic, and left gastric arteries, in 90.9% of the dissections (70/77). Two different types of trifurcation were observed: (a) a true tripod when the celiac trunk ended in a complete trifurcation (74.0%, 57/77) and (b) a false tripod when the three arteries did not have a common origin (16.9%, 13/77). Such a clear predominance of the true tripod is not reported elsewhere. Anatomic variations were found in 9.1% (7/77). Bifurcation of the celiac trunk into splenic and left gastric artery (splenogastric trunk) was observed in one specimen (1.3%), whereas the common hepatic artery emerged directly from the aorta. Absence of the celiac trunk was also found in two individuals (2.6%). The celiac trunk presented additional branches (lumbar and inferior phrenic arteries) in 5.2% (4/77). The median level of origin of the celiac trunk was at the upper third of L1 (22.7% to 17/75). The total length of the celiac trunk ranged from 1.1 to 5.0 cm, whereas the mean length was 2.8 cm (standard deviation = 0.80 cm, standard error of mean = 0.09 cm) irrespective of the existence of variations. The mean length of the celiac arteries which formed a false tripod was found to be larger than those of the arteries which formed a true tripod but only a weak statistically significant difference was established (P = 0.073).

Study of the Association of Insecure Attachment With the Dehumanization and Self-Dehumanization of Patients Hospitalized With Psychotic Disorder and Organic Disease.

Introduction Dehumanization is the phenomenon that concerns the non-attribution of humanness to other human beings and has two dimensions, animalistic and mechanistic. The aim of the present study is to study dehumanization and self-dehumanization in patients with psychosis and organic disease. Methods The sample consisted of 200 people who were hospitalized in Athens, Greece, in 2017. Participants were asked to answer the dehumanization questionnaire, the mechanistic self-dehumanization scale, the human nature and human uniqueness characteristics questionnaire, and the adult attachment questionnaire.  Results It was found that patients with organic disease and patients with psychosis do not perform mechanistic and animalistic dehumanization of themselves. Still, it seems that insecure attachment (anxiety and obsession) contributes positively to their mechanistic dehumanization and negatively to their mechanistic self-dehumanization. From the insecure attachment, only the dimensions of stress and obsession affect the mechanistic dehumanization.  Conclusions It is important to take measures to train specialists in the hospital so that they can establish a safe therapeutic relationship with the patient so that patients will not resort to dehumanization and self-dehumanization as a defense against the stress of hospitalization.

Health Professionals in a COVID-19 Reference Hospital: Post-traumatic Stress Disorder (PTSD) Levels and Their Associations With Psychological Resilience and Quality of Life.

Introduction The coronavirus disease 2019 (COVID-19) pandemic has affected the quality of life of both the general population and health professionals and has increased the levels of psychopathology among them. The present study aims to map the levels of post-traumatic stress disorder (PTSD), psychological resilience, and quality of life of healthcare professionals who work in a COVID-19 reference hospital in Athens, Greece, one year after the onset of the pandemic. Also, this study focuses on investigating the relationships among the study variables and demographics and examining possible mediating effects. Methods The sample consisted of 400 health professionals from Sotiria Hospital, of whom 102 were men. Participants were asked to complete the Post-Traumatic Stress Scale, Connor-Davidson Resilience Scale, and the WHO Quality of Life Questionnaire. The survey was conducted from May to July 2021. Results The findings show statistical differences in resilience levels regarding marital status and employee education. Also, 13.5% of the staff reported significant PTSD levels, which relate to low levels of psychological resilience and every pillar of quality of life. Conclusions Thus, research findings indicate that resilience levels could have a protective effect on the development of PTSD symptoms. Therefore, the design of group interventions that aim at building health workers' resilience will be discussed.

The Effect of Personality Traits on the Quality of Life of Health Professionals in COVID-19 Reference Hospital.

Introduction and objectives Coronavirus disease 2019 (COVID-19) has affected the quality of life of both general population and the healthcare workers and has increased the psychopathology levels. The objective of this research was to study the personality traits and the quality of life of healthcare professionals during the COVID-19 pandemic, in order to organize and apply interventions for the well-being of the staff. Materials and methods The study sample consisted of 400 healthcare workers, in Thoracic Diseases General Hospital "Sotiria". Participants were asked to provide sociodemographic information and to complete: (1) the WHOQOL-BREF, (2) the NEO-FFI. The questionnaire was administered in person to the hospital staff. The data were collected between May and July 2021, in Athens, Greece. Results Younger healthcare professionals had a better quality of life and with regard to gender differences, males reported higher scores of physical and psychological health compared to females. Also regarding personality traits, neuroticism and extroversion have a statistically significant effect on the quality of life. In contrast, education level, work area and specialty did not appear to affect the quality of life of hospital staff. Conclusions From our research findings, it appears that quality of life has been affected by the COVID-19 pandemic. Interventions are needed to apply mindfulness, increase well-being and form groups with the hospital staff in order to share their experiences.

Investigation of the Relationship Between Aggression and Adult Attachment in Healthcare Professionals.

Introduction Multiple references to the violent and especially difficult patient have been presented by the international literature. However, there is little literature on the aggressive behaviors of health professionals in their workplaces. The aim of this research is to record and correlate aggression and attachment type data of adult health professionals. Methods The sample includes 192 individuals (43 men and 149 women) health professionals in the private and public sector, aged 20 to 60 years, who were selected by the method of random sampling. The survey was conducted from February 2018 to May 2018. The Greek version of the Aggression Questionnaire and the Greek version of the Revised Experiences in Close Relationships (G-ECR-R) self-report inventory were used and the analysis was performed with the Statistical Package of Social Sciences (SPSS 26) (IBM Corp., Armonk, NY). Results The analysis shows that the dimension of avoidance has a positive correlation with hostility and physical aggression and the dimension of stress has a positive correlation with anger, physical aggression and hostility. It also seems that the stress dimension of the adult attachment contributes significantly positively to the prediction of anger and the stress dimension contributes significantly to the prediction of hostility. The dimension of avoiding adult attachment contributes significantly to the prediction of physical aggression. Conclusions To our knowledge, no studies were found in the literature to examine the relationship between the subscales of aggression and dimensions of attachment. It is important that violence in the workplace is recognized as an underlying occupational risk and not just as a matter of criminal law. Finally, more research is needed to study the phenomenon in order to make it more understandable.

Dehumanization of Hospitalized Patients and Self-Dehumanization by Health Professionals and the General Population in Greece.

Introduction Dehumanization is defined as the denial to people of their humanness. It is distinguished into animalistic and mechanistic dehumanization. The aim of this study is to examine whether professionals in a public hospital dehumanize the patient and self-dehumanize. Methods We used the Dehumanization Questionnaire, the Mechanistic Self-Dehumanization Scale, the Human Nature and Human Uniqueness Characteristics Questionnaire, the General Causality Orientation Scale and the Adult Attachment Questionnaire. The sample consisted of 135 mental health professionals (20 from a general hospital and 115 from a psychiatric hospital), 134 other health professionals from the general hospital and 84 people from the general population. Results  Health professionals dehumanize the hospitalized patient more than the general population. The secure attachment acts protectively on self-dehumanization and negatively on the dehumanization of the hospitalized patient. Finally, autonomous people are not self-dehumanized. Conclusions Our findings indicate that measures should be taken for health professionals so that they do not dehumanize the patient.

Cutaneous Vasculopathy in a COVID-19 Critically Ill Patient: A Histologic, Immunohistochemical, and Electron Microscopy Study.

We describe a critically ill, SARS-CoV-2 positive patient with respiratory failure and thrombotic/livedoid skin lesions, appearing during the course of the disease. The biopsy of the lesions revealed an occlusive, pauci-inflammatory vasculopathy of the cutaneous small vessels characterized by complement and fibrinogen deposition on vascular walls, pointing to a thrombotic vasculopathy. Transmission electron microscopy of the affected skin failed to reveal any viral inclusions. Clinical evaluation and laboratory findings ruled out systemic coagulopathies and disseminated intravascular coagulation, drug-induced skin reaction, and common viral rashes. Our hypothesis is that the, herein evidenced, microvascular occlusive injury might constitute a significant pathologic mechanism in COVID-19, being a common denominator between cutaneous and pulmonary manifestations.

Preventing syphilis in the 16th century: the distinguished Italian anatomist Gabriele Falloppio (1523-1562) and the invention of the condom.

By the end of the 15th century, syphilis had reached epidemic proportions in Europe. Unable to ascertain its causes, physicians resorted to superstition. At the beginning of the 16th century, the sexual transmission of the disease was established. Initially, the principal measure of infection control was sexual abstinence and mutual fidelity. However, during the same period the Italian anatomist Gabriele Falloppio (1523-1562) proposed a method of preventing syphilis transmission: the medication-soaked linen sheath. Thus was born the idea of a mechanical barrier against sexually transmitted diseases: the condom.

A morphometric study of multiple renal arteries in Greek population and a systematic review.

The aim of the study was to determine the distribution patterns of multiple renal arteries, evaluate how they are affected by gender and bilateral asymmetry and proceed on a systematic review. Two hundred and six kidneys from 103 Greek cadavers (53 males and 50 females) were investigated. The number and pattern of multiple renal arteries were determined according to side, gender and level of origin. The distances between the main renal and first multiple renal arteries were also measured. Multiple renal arteries were present in 11.2% of the kidneys. No statistically significant difference was found between side and gender (p>0.05). The incidence of multiple renal arteries was 87% unilaterally and 13% bilaterally. As regards the multiple renal arteries, a single artery was detected in 83%, two in 13% and three in 4.3%. In 30.4% (7/23) of the kidneys, there was a short common trunk (<1.5 cm), early dividing into the main renal artery and a thinner artery. Multiple renal arteries on the left side seemed to emerge lower than the right ones and displayed a greater variability at their origin. In the systematic review, we detected the patterns of multiple renal arteries which were classified according to population, gender, side and specimen (cadaveric, radiological or transplant). The awareness of morphology and topography of the multiple renal arteries is important in order to achieve a safe pre and intraoperative management of the renal vascular supply.

A rare variation of the axillary artery combined contralaterally with an unusual high origin of a superficial ulnar artery: description, review of the literature and embryological analysis.

During anatomical dissection of a female Caucasian cadaver in our department we observed a combination of two rare arterial patterns of the upper limb bilaterally; a superficial ulnar artery of high origin in the right upper limb and some rare variations of the left axillary artery: Right arm: The superficial ulnar artery originated from the second part of the axillary artery, before the origin of the subscapular artery. It proceeded superficially in the forearm. The axillary artery continued normally in the arm as brachial artery, and finally divided into the radial and the common interosseous artery. The normal ulnar artery was absent. The presence of the superficial ulnar artery is a rare variation given that its total incidence ranges from 0.67% to 9.38%, with only 0.17% to 2% originating from the axillary artery. Left arm: The second part of the axillary artery gave rise to a first common trunk (named A), lying between the two roots of the median nerve, which divided in two new common trunks (B and C). One of these gave origin to the subscapular and the posterior circumflex humeral artery while the other gave rise to the anterior circumflex humeral artery, two muscle twigs and then continued as profunda brachii artery. The incidence of anatomic variations of the major arteries of the upper extremities ranges from 11% to 24%. Nevertheless a pattern with three common trunks comprising the origin of the profunda brachii has not yet been cited in the literature.

An unusual termination of seven veins in the jugulo-subclavian junction / Inusual terminación de siete venas en la unión yugulo-subclavia

During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

Durante la disección anatómica de un cadáver caucásico femenino, se observó una inusual terminación de siete venas en el lugar de unión yúgulo-subclavia. Normalmente, la unión yúgulo-subclavia consiste en la unión de la vena yugular interna y la vena subclavia, que forman la vena braquiocefálica. En nuestro caso, además de estas dos venas, se observaron cinco venas adicionales, la vena cefálica, la vena cervical transversa, la vena yugular externa, la vena yugular anterior y la vena vertebral, la que también se unió en el nivel de la unión yúgulo-subclavia, a fin de formar la vena braquiocefálica. Tal variación no ha sido reportado en la literatura.
