Abstract
OBJECTIVES To understand the nomenclature of the hyoid bone. MATERIALS AND METHODS Hyoid, a small bone of the neck, is a bony part that is rather difficult to unearth and discover among skeletal remains. RESULTS The named was coined by the ancient Greeks, along with its anatomic description. Galen (2nd - 3rd c. AD) and Theophilus Protospatharius (7th century AD), facing religious and social barriers, succeeded in presenting its anatomy and suggesting its probable function in speech and swallowing, regarding the bone as a muscle pillar of the neck area. CONCLUSION Authorities of Hellenic antiquity surprise us with their accuracy and the resilience of their anatomical descriptions.

Abstract
Introduction: Cilostazol is a selective cyclic inhibitor of the 3-phosphodiesterase type (PDE3) that is recommended to be administered in cases of symptomatic peripheral vascular disease (YEI). It was discovered as a chemical compound in the 1980s, in Takao Nishi laboratory in Japan. Objective: The purpose of the present review was to evaluate the efficacy of cilostazol administration in a YEI with intermittent claudication or moderate to severe lower extremity ischemia. Materials and methods:A systematic review of the literature was carried out where articles were searched in the international database PubMed. The year 2005 was set as a time limit for the publication date of the articles. The following keywords were used: cilostazol, peripheral arterial disease, revascularization and lower limb. A total of 95 articles were found, of which only 10 were selected for the present study. Results:According to the results of the current review, the use of cilostazol increases the ability to walk, improves the quality of life, reduces the rates of re-narrowing of vessels and stents, reduces the likelihood of amputation and is co-administered with other antiplatelet and anticoagulant agents. Conclusion:Cilostazol administration should be a possible treatment option for symptomatic YEI. Further research is necessary to determine its safety after three years.

Abstract
BACKGROUND There are limited data on the attitudes and acceptance of the second booster (fourth dose) of the COVID-19 vaccination among physicians. METHODS A cross-sectional, questionnaire-based, online study was conducted among members of the Athens Medical Association (A.M.A.) who were invited to participate anonymously over the period from January to March 2023. RESULTS From the 1224 members who participated in the survey, 53.9% did not receive the fourth dose of the COVID-19 vaccine. The main reasons for no vaccination were the lack of obligation to receive the fourth dose, the history of three doses of the COVID-19 vaccine and the lack of sufficient information about the effectiveness of the fourth dose. Over half of the three-dose-vaccinated participants were willing to receive the fourth dose in the near future. Interestingly, the vaccination coverage among participants who had been informed about the fourth dose through scientific sources was low. CONCLUSIONS The low vaccination coverage with the fourth dose reported in this study can lead to broad and serious consequences, such as increase in COVID-19 infections, reduction of available healthcare staff and increased caseloads of COVID-19 in hospitals. Furthermore, hesitant physicians will adversely influence the vaccination uptake among the general population due to their key role in informing and recommending the vaccine. The healthcare system administration should acknowledge and address physician's concerns through effective communication and better support.

Abstract
The aim of the present paper is to contribute to the understanding of the history of the anatomical study of the intra-renal arteries. The vasculature and especially the intra-renal arteries of the kidneys are an intriguing field which was first studied through art and then perfected by medicine. Angiography and microsurgery have resulted in partial nephrectomy techniques for surviving kidneys with adequate functional results. Graves' categorization dating from 1954 opened the way for innovative approaches that have resulted in modern topographical anatomy. CONCLUSION: Our understanding of the anatomy of intra-renal arteries has played a significant role in surgical anatomy and internal medicine.

Abstract
The first extensor wrist compartment (FEWC) displays significant variants. This review highlights all possible variants that may be associated with the occurrence and pathophysiology of de Quervain's tenosynovitis. A thorough search of PubMed and MEDLINE databases, following the PRISMA guidelines, was conducted from 2002 to 2022 to evaluate all FEWC variants, including the following: 1) the presence of an inter-tendinous septum, 2) the number of tendinous slips of the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB) muscles, 3) their distal insertions and 4) the presence of a bony ridge within the FEWC. A total of 3878 wrists (1277 cadaveric and 1296 de Quervain patients) were included. Of the 1234 cadavers, a total of 701 (56.8%) were males and 533 (43.2%) were females. Regarding the 883 patients, 178 (20.2%) of them were males and 705 (79.8%) were females. An inter-tendinous septum was identified in 42.9% (47% of the patients' wrists compared to 39.3% of the cadaveric wrists, p<0.0001). Cadaveric wrists presented two or more slips for the APL in a significantly higher percentage (92.5%, p < 0.0001) compared to de Quervain patients' wrists (74.5%). Regarding the EPB muscle, de Quervain patients' wrists had a single slip in 93% (p=0.0007) and two or more slips in 3.6%, compared to cadaveric wrists (a single slip in 87%, and two or more slips in 11%, p< 0.0001). A bony ridge over the radial styloid process was recorded in 58.9% of the cadaveric wrists compared to 17.8% of the patients' wrists (p < 0.0001). Remarkable diversity concerning the structures within the FEWC was reported. The presence of an inter-tendinous septum dividing the FEWC and a single EPB muscle slip is more likely to be found in patients with de Quervain's disease.

Abstract
The aim of the present paper is to contribute to the understanding of the history of the anatomical study of the facial artery. The facial artery plays a fundamental role in the study of the anatomy of the face, and in maxillofacial and vascular surgery. The debate on the understating of this vessel is essential in the educational process, with special focus on the historical development of topographical and descriptive ideas about it. The comparison between the study of facial artery in the work of Thomas Turner (1793-1873) and modern anatomical concepts serves as an excellent educational paradigm. The documentary research method was used this short historical survey. CONCLUSION: Thomas Turner laid the scientific foundation for the accurate anatomical study of the facial artery.

Abstract
Healthcare workers are at high risk of influenza virus infection as well as of transmitting the infection to vulnerable patients who may be at high risk of severe illness. The aim of this cross-sectional study was to investigate the prevalence and related factors of influenza vaccination coverage (2020-2021flu season), among members of the Athens Medical Association in Greece. This survey employed secondary analysis data from a questionnaire-based dataset on COVID-19 vaccination coverage and associated factors from surveyed doctors, registered within the largest medical association in Greece. All members were invited to participate in the anonymous online questionnaire-based survey over the period of 25 February to 13 March 2021. Finally, 1993 physicians (60% males; 40% females) participated in the study. Influenza vaccination coverage was estimated at 76%. Logistic regression analysis demonstrated that older age (OR = 1.02; 95% C.I. = 1.01-1.03), history of COVID-19 vaccination (OR = 2.71; 95% C.I. = 2.07-3.56) and perception that vaccines in general are safe (OR = 16.49; 95% C.I. = 4.51-60.25) were found to be independently associated factors with the likelihood of influenza vaccination coverage. Public health authorities should maximize efforts and undertake additional actions in order to increase the percentage of physicians/health care workers (HCWs) being immunized against influenza. The current COVID-19 pandemic offers an opportunity to focus on tailored initiatives and interventions aiming to improve the influenza vaccination coverage of HCWs in a spirit of synergy and cooperation.

Abstract
There are limited data on the prevalence and determinants of COVID-19 vaccination coverage among physicians. A cross-sectional, questionnaire-based, online study was conducted among the members of the Athens Medical Association (I.S.A.) over the period 25 February to 13 March 2021. All members of I.S.A. were invited to participate in the anonymous online survey. A structured, anonymous questionnaire was used. Overall, 1993 physicians participated in the survey. The reported vaccination coverage was 85.3%. The main reasons of no vaccination were pending vaccination appointment followed by safety concerns. Participants being informed about the COVID-19 vaccines by social media resulted in lower COVID-19 vaccination coverage than health workers being informed by other sources. Logistic regression analysis demonstrated that no fear over COVID-19 vaccination-related side effects, history of influenza vaccination for flu season 2020–2021, and the perception that the information on COVID-19 vaccination from the national public health authorities is reliable, were independent factors of reported COVID-19 vaccination coverage. Our results demonstrate a considerable improvement of the COVID-19 vaccination uptake among Greek physicians. The finding that participants reported high reliability of the information related to COVID-19 vaccination provided by the Greek public health authorities is an opportunity which should be broadly exploited by policymakers in order to combat vaccination hesitancy, and further improve COVID-19 vaccination uptake and coverage among physicians/HCWs, and the general population.

Abstract
Background
The suprascapular notch (SN) represents the point along the route of the suprascapular nerve (SSN) with the greatest potential risk for injury and compression. Thus, factors reducing the area of the notch have been postulated for suprascapular neuropathy development.
Methods
Thirty-one fresh-frozen shoulders were dissected. The contents of the SN were described according to four types as classified by Polguj et al and the middle-transverse diameter of the notch was measured. Also, the presence of an ossified superior transverse scapular ligament (STSL) was identified.
Results
The ligament was partially ossified in 8 specimens (25.8%), fully ossified in 6 (19.35%), and not ossified in the remaining 17 (54.85%). The mean middle-transverse diameter of the SN was 9.06 mm (standard deviation [SD] = 3.45). The corresponding for type-I notches was 8.64 mm (SD = 3.34), 8.86 mm (SD = 3.12) was for type-II, and 14.5 mm (SD = 1.02) was for type III. Middle-transverse diameter was shorter when an ossified ligament was present (mean = 5.10 mm, SD = 0.88 mm), comparing with a partially ossified ligament (mean =7.67 mm, SD = 2.24 mm) and a nonossified one (mean = 11.12 mm, SD = 2.92 mm). No statistically significant evidence was found that the middle-transverse diameter depends on the number of the elements, passing below the STSL.
Conclusion
Our results suggest that SSN compression could be more likely to occur when both suprascapular vessels pass through the notch. Compression of the nerve may also occur when an ossified transverse scapular ligament is present, resulting to significant reduction of the notch's area.

Abstract
Juvenile idiopathic arthritis (JIA), is a term used to describe a group of inflammatory disorders
beginning before the age of 16 years. Although for the majority of children remission is achieved
early, those with systemic or polyarticular form of the disease may present persistent symptoms in
adulthood. Considering that there is overlap in the pathogenesis of JIA with adult rheumatic diseases,
concerns have been raised as to whether JIA patients could be at increased cardiovascular (CV) risk in
the long-term. In this review, we summarize evidence for CV involvement in JIA and present data on
CV risk factors and surrogate markers of arterial disease. We also provide information on beneficial and
harmful CV effects of anti-inflammatory medications in the context of JIA and suggest strategies for
CV screening. Overall, patients with systemic forms of JIA demonstrate an adverse lipid profile and
early arterial changes relevant to accelerated arterial disease progression. Although there is paucity of
data on CV outcomes, we recommend a holistic approach in the management of JIA patients, which
includes CV risk factor monitoring and lifestyle modification as well as use, when necessary, of antiinflammatory
therapies with documented CV safety.

Abstract
OBJECTIVE The aim of our paper is to depict an anatomical variation of the brachial plexus, concerning a communicating branch between the median and the musculocutaneous nerve and its clinical significance. Anatomical variations of the brachial plexus and especially those of the musculocutaneous nerve are quite common. Awareness of these variations is of paramount importance in clinical practice, mainly in achieving best results in minimal invasive or surgical procedures. CASE REPORT After dissection in upper extremities in a 89-year-old male cadaver, a communicating branch between the median and the musculocutaneous nerve was found. This communicating branch was formed before the musculocutaneous nerve perforated the coracobrachialis muscle. It also derived from the level of the ansa medianis and its course was of an approximately 2cm length. CONCLUSION The clinical significance of our study is the entrapment of the musculocutaneous nerve that may cause clinical findings similar to those of the carpal tunnel syndrome.

Abstract
Dental biofilm is a complex, organized microbial community that is the primary etiologic factor for plaque, the most frequently occurring oral contamination for gingivitis, dental caries and periodontal diseases. In dentistry, calculus is a form of hardened dental plaque, caused by precipitation of calcium (Ca) and phosphorous (P) ions deposited from saliva and gingival crevicular fluid. Although the dental biofilm cannot be eliminated, it can be controlled with comprehensive mechanical and chemotherapeutic oral hygiene practices. Chemotherapeutic agents have difficulty penetrating the polysaccharide matrix to reach and affect the microorganisms. The purpose of the present study was to evaluate the anti-calculus efficiency of a mouthwash containing an association of sodium tripolyphosphate, tetrapotassium pyrophosphate, sodium bicarbonate and citric acid in patients affected with gingivitis.

Abstract
PURPOSE In this study the temporal texture differentiation associated with the bone formation properties, around loaded oral implants after Platelet Rich Plasma (PRP) employment, was investigated in Panoramic Radiographs. MATERIALS AND METHODS Thirty eligible patients are randomly assigned to two groups. The test group received PRP application around new implants, while in the control group no PRP treatment was made. The bone-to-implant contact region was analyzed in a clinical sample of 60 Digitized Panoramic Radiographs, 30 corresponding to immediate implant loading (Class-I) and 30 after an 8 month follow-up period (Class-II). This region was sampled by 1146 circular Regions-of-Interest (ROIs), resulting from a specifically designed segmentation scheme based on Markov-Random-Fields (MRF). From each ROI, 41 textural features were extracted, then reduced to a subset of 4 features due to redundancy and employed as input to Receiver-Operating-Characteristic (ROC) analysis, to assess the textural differentiation between two classes. RESULTS The selected subset, achieved Area-Under-Curve (AUC) values ranging from 0.77-0.81 in the PRP group, indicating the significant temporal textural differentiation has been made. In the control group, the AUC values ranged from 0.56-0.68 demonstrating lesser osseo integration activity. CONCLUSION This study provides evidences that PRP application may favor bone formation around loaded dental implants that could modify the dental treatment planning.

Abstract
A study of the matrix effect was performed in order to evaluate the influence of some matrices on the gas chromatographic responses of representative organophosphorus insecticides. In particular, three fortification levels and the maximum residual level of four organophosphorus pesticide standard solutions were added into 18 matrices (15 belonging to five specific botanical categories and three botanically unclassified). The recoveries of the examined pesticides were determined using a simple official multiresidue method of detection, without any additional clean-up step. Recoveries were estimated based on standards prepared in solvent. The recovery percentages of the most polar pesticides, especially methamidophos (20.2-288.4%), were much higher than those of non-polar ones (chlorpyrifos and methidathion 25.7-136.4 and 37.6-292.6%, respectively), except for quince. Pronounced matrix effects (>120%) were observed to the lowest fortification levels (maximum residual levels established by the European Union), of dimethoate and methamidophos (i.e. the most polar analytes) in the majority of product extracts. Furthermore, it was proved that there is no correlation between the classification of plant products, according to their botanical characteristics, and the recoveries of pesticides in the equivalent extracts. Indeed, there were significant differences in the recoveries of pesticides in extracts, derived from matrices belonging to the same botanical group (especially in the categories of pome fruits and citrus). Consequently, it was shown that, under the examined conditions, obtaining recovery data, derived from only one representative matrix, with the purpose to validate an official method in its botanical category is, possibly, an erroneous practice.

Abstract
Tetanus is still a common problem in countries with poor health conditions. On the contrary, where there is a systematic program of vaccination in children it is very rare. The aim of this study was to check the immunity level of a representative sample of rural people from villages of Achaia County in Southern Greece. Samples were taken from 140 locals during a six-month period (January till July 2002). In each sample, we estimated IgG antibodies against Clostridium tetani toxin. A protection level of 0.1 IU/ml was set. 15.7% of the people had sufficient immunization cover while a statistically significant superiority of immunized men was found. The results of this study revealed low immunity percentage of the examined inhabitants and a vaccination program against the disease has been proposed to the local health authorities.

Abstract
From 1915 [corrected], the first time a flight surgeon participated in an aeromedical evacuation, to the present, the role has become more fundamental by working in wars and operations, experiencing search and rescue aeromedical evacuations from mass accidents or motor accidents, treating seriously ill individuals, and caring for wounded victims of attacks either at the scene or at the hospital. The improvements in cognitive and technological standards of medical science and in the education available have contributed in upgrading the role of flight surgeons; however, their presence in flight is considered essential in 20-60% of aeromedical evacuations, with the remainder of the flights being covered by paramedical personnel. In the Greek territory, the development of Air Force medicine began with the U.S. education of Panagiotis Korombilis, founder of the Center for Flight Crew Health Examination in 1936. In 1976, the Air Force Medical Center was established in the General Air Force Hospital while the educational and medical work of Air Force physicians led to the development of Air Force Medicine and supported Olympic Airways and Military Air Force development, which provides aircraft and personnel for patient aeromedical evacuations. An organized aeromedical evacuation system based on the National Health System, however, began operating in 1982 and was upgraded in 1994. Currently, the flight surgeon's work remains important in supporting the Military Air Force by offering regular examinations at the Air Force Medical Center for all personnel flying on civil and military aircrafts, and by educating all the Greek territory and Cypriot Air Force surgeons (of the National Emergency Assistance Center and the Military Services) at the Air Force Medical Center. Their presence at Air Force bases is important, as is their support of the overall well-being of flight personnel, their assistance in upholding the territory's future by improving aircraft and equipment and by purchasing search-rescue aeromedical evacuation helicopters and hospital aeromedical transportation aircraft capable of transporting seriously ill patients, their promotion of collaboration with other countries in educating Air Force surgeons, and in support of valuable human life according to the Hippocratic Oath.

Abstract
The penetration of ceftriaxone into the fetus at parturition was studied in 17 subjects. Despite its high protein binding, ceftriaxone quickly reached the umbilical cord blood, amniotic fluid, and placenta, achieving substantial concentrations, which then disappeared, with elimination half-lives of approximately 6 h, identical to that of the mother. The elimination half-life of ceftriaxone of 5 to 6 h in these mothers was somewhat shorter than that reported for normal subjects. The concentrations of ceftriaxone achieved in fetal tissues were sufficient for therapeutic effects. The penetration of ceftriaxone into milk was studied 3 days postpartum in 20 other patients. This antimicrobial agent entered breast milk rapidly and disappeared with a half-life of 12 to 17 h. The concentrations achieved were only 3 to 4% of those in maternal serum and were most likely of little clinical relevance.
