Abstract
OBJECTIVE Mucoepidermoid carcinomas (MEC) of the larynx account for less than 1% of all laryngeal tumors. The unique features and clinical behavior of these rare entities remain unknown. To fill this knowledge gap, we performed a scoping review of every reported case of laryngeal MEC to study the clinical behavior and the treatment modalities in this rare entity. REVIEW METHODS We followed the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) statement. DATA SOURCES MedLine, Google Scholar, and Science Direct databases were searched to identify eligible studies. RESULTS We concluded with 25 studies and overall 66 cases. Our study revealed that the average age of cases was 55.7 years, and the range was from 12 to 81 years, with younger onset in females. Supraglottic (60%) is the most common subsite of laryngeal MEC s followed by glottis (27.3%). Supraglottic carcinomas frequently present with metastatic neck disease at the time of the initial diagnosis and require more extensive surgical approaches. Surgery with negative surgical margins seems to be the cornerstone in the treatment of MEC. Radiation therapy has not been tested widely as monotherapy but is considered a useful adjuvant modality. CONCLUSION This study suggests that negative surgical margins seem to be associated to higher disease control rate and that high-grade supraglottic cases likely benefit from addressing neck disease simultaneously. LEVEL OF EVIDENCE NA Laryngoscope, 134:2578-2584, 2024.

Abstract
The standard dorsal portals are the most commonly used in wrist arthroscopy. This cadaveric study aims to determine safe zones, by quantitatively describing the neurovascular relationships of the dorsal wrist arthroscopy portals: 1-2, 3-4, midcarpal radial, midcarpal ulnar, 4-5, 6-radial and 6-ulnar. The neurovascular structures of twenty-one fresh frozen human cadaveric upper limbs were exposed, while the aforementioned portals were established with needles through portal sites. The minimum distance between portals and: dorsal carpal branch of radial artery, superficial branch of radial nerve, posterior interosseous nerve and dorsal branch of ulnar nerve, were measured accordingly with a digital caliper, followed by statistical analysis of the data. The median and interquartile range for each portal to structures at risk were determined and a safe zone around each portal was established. Free of any neurovascular structure safe zones surrounding 1-2, 3-4, midcarpal radial, midcarpal ulnar, 4-5, 6-radial and 6-ulnar portals were found at 0.46mm, 2.33mm, 10.73mm, 11.01mm, 10.38mm, 5.95mm and 0.64mm respectively. Results of statistical analysis from comparisons between 1-2, 3-4 and midcarpal radial portals, indicated that 1-2 was the least safe. The same analysis among 3-4, midcarpal radial, midcarpal ulnar and 4-5 portals indicated that midcarpal portals were safer, while 3-4 was the least safe. Results among midcarpal ulnar, 4-5, 6-radial and 6-ulnar portals indicated that 6-radial and specifically 6-ulnar were the least safe. This study provides a safe approach to the dorsal aspect of the wrist, enhancing established measurements and further examining safety of the posterior interosseous nerve.

Abstract
Rare facial nerve branching patterns, pose dangers due to their unexpected course. Cases with multiple branches may reduce the intraoperative risk, due to the compensation of adjacent branches. We present a case of a cadaveric specimen where an early trifurcation of the mandibular branch of the facial nerve was noted.

Abstract
PURPOSE The anatomy education literature suggests blended-learning approaches as more effective. We performed a literature review to answer the question if virtual dissection tables can play a significant role as supplements to traditional cadaver-based anatomy education methods. METHODS PubMed, SCOPUS, ERIC and Cochrane databases were searched for articles with purpose to explore the outcomes of the use of virtual dissection tables in conjunction with cadaver-based anatomy education. RESULTS Six articles were included. Three articles were comparative and comprised evaluation of participants' anatomy examinations results. Three articles were non-comparative and comprised only evaluation of participants' opinions about the educational intervention. In all studies, the participants expressed satisfaction about the educational value of this intervention, while the data about anatomy examinations' results suggest that virtual dissection tables may also enhance students' academic performance, when they are used in conjunction with cadavers. CONCLUSION Virtual dissection tables seem to do have a role in modern blended-learning anatomy curricula and could essentially supplement the educational power of cadaver-based methods. Our findings may stimulate further implementation of virtual dissection tables as supplementary tools to cadaver-based anatomy education.

Abstract
PURPOSE The superior thyroid artery (STA) point of origin is strongly debated with controversial results among studies. External carotid artery (ECA), carotid bulb, and common carotid artery (CCA) have been presented as points of origin with variable percentages among authors. We conducted a systematic review of all existing studies that included cadaveric, surgical, and angiographic specimens and recorded the origin of STA according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. MATERIALS AND METHODS Fifty-two studies, with an overall of 5488 specimens were included. RESULTS Our results indicated ECA as the most common site of origin (55.0 %) followed by carotid bifurcation at 27.5 % and CCA at 15.0 %. Absent STA or branching from the internal carotid artery (ICA) was an extremely rare finding. We proposed a new simple classification system based on our results. CONCLUSIONS The huge variability in the branching pattern of STA makes head and neck surgery and radiographic interventions challenging and poses the integrity of STA at risk. Therefore, we strongly recommend preoperative angiographic studies for STA identification to prevent an intraoperative iatrogenic injury.

Abstract
PURPOSE The educational use of gestures has resulted in positive outcomes in several fields. We performed a literature review to investigate the outcomes of the use of gestures to enhance the existing anatomy education methods. METHODS PubMed, SCOPUS, ERIC and Cochrane databases were searched for papers with purpose to investigate the outcomes of the use of gestures (either seeing or performing them or both) as adjuncts to existing anatomy education methods. RESULTS Six articles were included. Three studies comprised both seeing and performing gestures by the students, while the remaining three studies only comprised either seeing or performing gestures by the students. Most studies evaluated the acquisition of anatomical knowledge after the educational intervention and demonstrated that the addition of gestures resulted in significant benefit compared to control groups, while positive students' perceptions were recorded. It was not clarified whether seeing or performing gestures by the students leads to better educational outcomes. CONCLUSION Gestures-enhanced anatomy education seems to be a promising teaching strategy, given that it has led to significantly increased acquisition of anatomical knowledge compared to no gestures-enhanced modalities. The addition of gestures to existing anatomy education modalities seems able to increase their potential without increasing their cost. Further research is needed to determine if seeing or performing gestures by the students is more effective.

Abstract
The hypothenar muscle with the greatest frequency of variations is the abductor digiti minimi manus. Except for morphological variations of this muscle, have also been reported cases of an extra wrist muscle, the accessory abductor digiti minimi manus muscle. This case report presents a rare case of an accessory abductor digiti minimi muscle characterized by an unusual origin from the tendons of the flexor digitorum superficialis. This anatomical variation was identified on a formalin - fixed male cadaver of Greek origin during routine dissection. This anatomical variation, which may result in Guyon's canal syndrome or complicate common wrist and hand surgical procedures such as the carpal tunnel release, should be known to orthopaedic surgeons and hand surgeons in particular.

Abstract
OBJECTIVE We aimed to explore to what extent the literature supports that the use of cadaveric computed tomography can play an important role in anatomy education. MATERIALS AND METHODS PubMed, SCOPUS, Education Resources Information Center and Cochrane Databases were searched for papers with purpose to explore the outcomes of the use of cadaveric computed tomography scans in anatomy education. The following data were obtained from each paper: authors, number of participants, type of study (comparative or not), level of outcome according to Kirkpatrick hierarchy, possible evaluation of statistical significance, acquisition of anatomical knowledge after the educational intervention and perceptions about the effectiveness of this intervention in anatomy learning. RESULTS Seven articles were included. Four of them evaluated students' knowledge after the use of cadaveric computed tomography scans in anatomy education and three papers evaluated only students' perceptions. Generally, the outcomes, which mainly concerned students' perceptions, were positive, while it was showed that students' academic performance may also be improved. CONCLUSIONS The outcomes of the use of cadaveric computed tomography scans in anatomy education encourage the implementation of this teaching modality in anatomy curricula. Further research, including comparative studies with evaluation of acquisition of students' knowledge, is needed to show if cadaveric computed tomography will be proved a remarkable supportive tool in anatomy educators' hands.

Abstract
PURPOSE Team-based learning is a strategy which has resulted in positive outcomes concerning health professions education. We aimed to shed light on the role of this strategy when it is incorporated in the cadaveric anatomy laboratory. METHODS We explored PubMed, SCOPUS, ERIC and Cochrane databases for articles with purpose to investigate the educational outcomes of the integration of team-based learning in the cadaveric anatomy laboratory. RESULTS Six articles were eligible for inclusion. One of them assessed only participants' opinions about the educational intervention and five papers evaluated students' knowledge. Overall, the research showed significant improvement in students' examinations performance and significant superiority to control groups, as well as positive perceptions. There are limited data regarding the factors which may contribute to this success, but it seems that particularly the degree of teacher's involvement and competency needs to be further investigated. CONCLUSION Anatomy educators may consider further adopting team-based learning to facilitate the achievement of the learning objectives of the cadaveric anatomy laboratory and increase the teaching potential of cadavers.

Abstract
<b>Introduction:</b> Patients often suffer from an elongated styloid process. This clinical entity is well known and is described as Eagle syndrome. The presence of this anatomical variation is not always associated with symptoms. However, there is a strong correlation between the elongated styloid process and Eagle syndrome </br></br> <b>Aim:</b> This study aims to calculate the incidence of elongated styloid processes in the Greek population, to analyze the morphometric characteristics of styloid processes, and to compare these among sexes. </br></br> <b>Material and methods:</b> This is a single-center retrospective study. All skulls were donated to the Department of Anatomy, the Ari-stotle University of Thessaloniki from January 2013 to May 2019 for research purposes. A styloid process longer than 30 mm was considered elongated. We used Welch’s t-test for the statistical analysis of the data. </br></br> <b>Results:</b> The prevalence of elongated styloid processes was 35%. The average diameter was 3.32 mm and the average total length was 25.02 mm. There was no statistically significant difference between male and female skulls, though the female styloid processes were slightly longer and the male ones were slightly wider. Symmetry was recorded in 31% of skulls. Average axial angle was 650 but in 4% of cases it was less than 20<sup>0</sup>. </br></br> <b>Conclusions:</b> The elongated styloid process is not a rare entity. Eagle syndrome should always be considered in the differential diagnosis when patients report chronic sore throat. Our anatomical findings add a new dimension to the etiopathogenesis of Eagle syndrome.

Abstract
IMPORTANCE One characteristic histopathological event in Alzheimer disease (AD) is cerebral amyloid aggregation, which can be detected by biomarkers in cerebrospinal fluid (CSF) and on positron emission tomography (PET) scans. Prevalence estimates of amyloid pathology are important for health care planning and clinical trial design. OBJECTIVE To estimate the prevalence of amyloid abnormality in persons with normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia and to examine the potential implications of cutoff methods, biomarker modality (CSF or PET), age, sex, APOE genotype, educational level, geographical region, and dementia severity for these estimates. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional, individual-participant pooled study included participants from 85 Amyloid Biomarker Study cohorts. Data collection was performed from January 1, 2013, to December 31, 2020. Participants had normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia. Normal cognition and subjective cognitive decline were defined by normal scores on cognitive tests, with the presence of cognitive complaints defining subjective cognitive decline. Mild cognitive impairment and clinical AD dementia were diagnosed according to published criteria. EXPOSURES Alzheimer disease biomarkers detected on PET or in CSF. MAIN OUTCOMES AND MEASURES Amyloid measurements were dichotomized as normal or abnormal using cohort-provided cutoffs for CSF or PET or by visual reading for PET. Adjusted data-driven cutoffs for abnormal amyloid were calculated using gaussian mixture modeling. Prevalence of amyloid abnormality was estimated according to age, sex, cognitive status, biomarker modality, APOE carrier status, educational level, geographical location, and dementia severity using generalized estimating equations. RESULTS Among the 19 097 participants (mean [SD] age, 69.1 [9.8] years; 10 148 women [53.1%]) included, 10 139 (53.1%) underwent an amyloid PET scan and 8958 (46.9%) had an amyloid CSF measurement. Using cohort-provided cutoffs, amyloid abnormality prevalences were similar to 2015 estimates for individuals without dementia and were similar across PET- and CSF-based estimates (24%; 95% CI, 21%-28%) in participants with normal cognition, 27% (95% CI, 21%-33%) in participants with subjective cognitive decline, and 51% (95% CI, 46%-56%) in participants with mild cognitive impairment, whereas for clinical AD dementia the estimates were higher for PET than CSF (87% vs 79%; mean difference, 8%; 95% CI, 0%-16%; P = .04). Gaussian mixture modeling-based cutoffs for amyloid measures on PET scans were similar to cohort-provided cutoffs and were not adjusted. Adjusted CSF cutoffs resulted in a 10% higher amyloid abnormality prevalence than PET-based estimates in persons with normal cognition (mean difference, 9%; 95% CI, 3%-15%; P = .004), subjective cognitive decline (9%; 95% CI, 3%-15%; P = .005), and mild cognitive impairment (10%; 95% CI, 3%-17%; P = .004), whereas the estimates were comparable in persons with clinical AD dementia (mean difference, 4%; 95% CI, -2% to 9%; P = .18). CONCLUSIONS AND RELEVANCE This study found that CSF-based estimates using adjusted data-driven cutoffs were up to 10% higher than PET-based estimates in people without dementia, whereas the results were similar among people with dementia. This finding suggests that preclinical and prodromal AD may be more prevalent than previously estimated, which has important implications for clinical trial recruitment strategies and health care planning policies.

Abstract
<p><strong>Objective</strong>. This report presents a unilateral branching pattern of the axillary artery (AA) represented by an unusual common trunk division, vessel multiplications and concomitant neural variations.</p><p><strong> Case Report</strong>. In a Greek male cadaver, the right AA branched into a subscapular trunk and two accessory lateral thoracic arteries of variable origin and course. Concomitantly, a high-level interconnection between the musculocutaneous and median nerves was identified, as an accessory lateral root of the median nerve. More interestingly, a rare innervation of the upper part of the latissimus dorsi muscle by a lower subscapular nerve was also revealed.</p><p><strong>Conclusion</strong>. In-depth knowledge of the typical and variant AA branching patterns and coexisting neural variations is of paramount importance for surgeons and interventional physicians, for a safer diagnosis and for performing uneventful procedures in that area.</p>

Abstract
BACKGROUND Slow gait speed has recently emerged as a potential prodromal feature of cognitive decline and dementia. Besides objective measurements, subjective motor function (SMF) difficulties might be present prior to the manifestation of gait disorders. OBJECTIVES To examine the association of walking time and the presence of SMF with future cognitive decline in cognitively normal individuals. DESIGN Longitudinal study. SETTINGS Athens and Larissa, Greece. PARTICIPANTS 931 cognitively normal individuals over the age of 64 with longitudinal follow-up from the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD). MEASUREMENTS We used a simple chronometer for recording objective walking time (OWT) and SMF was assessed using a self-reported physical functioning questionnaire. Generalized estimating equations (GEE) models were deployed to explore the associations between baseline OWT and SMF difficulties and the rate of change of performance scores on individual cognitive domains over time. Models were adjusted for age, years of education and sex. RESULTS Each additional second of OWT was associated with 1.1% of a standard deviation more decline per year in the composite z-score, 1.6% in the memory z-score, 1.1% in the executive z-score and 1.8% in the attention-speed z-score. The presence of SMF difficulties was not associated with differential rates of decline in any cognitive domain. CONCLUSION Gait speed can be indicative of future cognitive decline adding credence to the notion that gait speed might serve as a simple and easily accessible clinical tool to identify a larger pool of at risk individuals and improve the detection of prodromal dementia.

Abstract
Glomus tumor (GT) constitutes a rare, benign, soft-tissue tumor emerging from neuro-myo-arterial glomus bodies. Due to its rarity, and absence of typical symptoms, GT is usually misdiagnosed, with a potential risk of rupture and infection, or even malignant transformation. The present manuscript reports a rare case of a 17-year-old young woman with multiple GTs in her lower back, breach and left thigh that was surgically treated. The manuscript aims to highlight the importance of prompt diagnosis and surgical treatment of this peculiar tumor in young patients and raise surgeons’ awareness.

Abstract
Bilateral femoral hernia is a peculiar clinical condition, with female predominance, with only a few cases reported in the literature. There are only two cases of bilateral strangulated femoral hernias, and these occur solely in females. To our knowledge, in the present manuscript, a bilateral strangulated femoral hernia in a male patient is reported for the first time. A 68-year-old male proceeded to the emergency department of our institution with symptoms of bowel obstruction. Abdominal computed tomography, magnetic resonance imaging and subsequent emergency laparotomy revealed obstruction of the sigmoid colon and simultaneous necrosis of several loops of the small intestine due to bilateral strangulated femoral hernia. The operation was uneventful. Despite the scarcity of this clinical condition, surgeons' awareness is fundamental, in addition to deep knowledge of the pathology and the anatomy of femoral hernias, in order to diagnose and treat adequately strangulated and incarcerated femoral hernias.

Abstract
In the current study, we display a rare association of an aberrant innervation of the sternocleidomastoid muscle by the ansa cervicalis (AC) with a tortuous common carotid artery (TCCA). In specific, in a male cadaver we observed on the right side of the cervical region, a nerval branch of remarkable size originating from the most distal part of the AC's superior root and after piercing the superior belly of the omohyoid muscle innervated the distal portion of the sternocleidomastoid muscle. Furthermore, we noticed a tortuous course of the initial part of the right common carotid artery. We discuss the surgical significance of the awareness of AC's variations during neurotisation of the recurrent laryngeal nerve in cases of its damage, as well as the importance of aberrant innervation of the sternocleidomastoid muscle by AC for the preservation of muscle's functionality after accessory nerve's damage. Furthermore, we highlight the fact, that the knowledge of the relatively uncommon variant, such as TCCA is crucial for the physician in order to proceed more effectively in differential diagnosis of a palpable mass of the anterior cervical region or deal with symptoms such as dyspnea, dysphagia or symptoms of cerebrovascular insufficiency.

Abstract
Iulius Casserius is to be remembered for his excellent contributions in Anatomy and especially in Neuroanatomy. His persistent and meticulous scientific anatomical work resulted in the first record of the arterial circle of the brain 37 years before the comprehensive description by Thomas Willis. Casserius' great interest in the human brain led him to the discovery of plenty anatomical structures before their official documentation. Casserius was an excellent teacher and anatomist of a humble origin, who managed to be distinguished among other famous physicians of his era.

Abstract
Objectives: To evaluate clinical, electrophysiological, and neuroradiological factors which correlate with the prognosis in patients with mesial temporal lobe epilepsy (MTLE). Methods: This was a single-center prospective outcome study in patients with MTLE. The patients' family history, clinical characteristics, neurophysiological data (electroencephalography - EEG), neuroimaging, antiepileptic therapy, and outcome were collected and analyzed. The population was divided into four groups depending on the frequency of the seizures when they attended their last follow up. All variables and outcome measures were compared between the four groups. Results: In total 83 consecutive patients were included within the four groups. Group 1 (seizure-free) consisted of 7 patients, (9%), Group 2 (rare seizures) consisted of 15 patients (18%), Group 3 (often seizures) consisted of 30 patients (36%), and Group 4 (very often seizures) consisted of 31 patients (37%). The groups did not differ significantly in demographic characteristics. There was a strong positive correlation between resistance to therapy and sleep activation on EEG (p = 0.005), occurrence of focal to bilateral seizures (p = 0.007), automatisms (p = 0.004), and the number of previously used antiepileptic drugs (AEDs) (p = 0.002). There was no association between febrile convulsions (FC), hippocampal sclerosis (HS), and the outcome that was found. Conclusion: MTLE is a heterogeneous syndrome. Establishing the factors responsible for, and associated with, drug resistance is important for optimal management and treatment, as early identification of drug resistance should then ensure a timely referral for surgical treatment is made. This prospective study shows that sleep activation on EEG, ictal automatisms, occurrence of focal to bilateral tonic-clonic seizures, and increased number of tried AEDs are negative prognostic factors.

Abstract
Isolated rupture of the flexor hallucis longus tendon is an unusual injury. We present the case of a neglected flexor hallucis longus tendon closed traumatic rupture at the plantar aspect of the first phalangeal head of the great toe in a middle-age male. The injury occurred while he was dancing. Because end-to-end tendon suture was impossible, the ensuing gap was repaired using a free plantaris tendon graft. We present the operative repair benefit of the flexor hallucis longus tendon rupture to regain the function and strength of the interphalangeal joint of the hallux, avoid extension of the distal phalanx, and maintain the longitudinal arch of the foot.

Abstract
OBJECTIVE The study adds valuable information regarding lymphovenous communications between the thoracic duct and the azygos vein, which are very rarely discovered during anatomical dissections and very few cases have been mentioned worldwide. A detailed description of our findings and a brief review of the relevant literature are also provided. CASE REPORST In the current study, two sizeable obliquely directed lymphovenous anastomoses between the thoracic duct and the azygos vein at the midportion of the mediastinum are described in the same cadaver. CONCLUSION The existence of such anastomoses in humans, as well in animals, is a scientific issue under debate. Cases of rapid cancer spread could be potentially explained by the likely presence of the abovementioned communications.

Abstract
Neuroendocrine carcinoma (NEC) of the colon is a rare and very aggressive tumor with poor prognosis. The current case report presents a 53-year-old male with a 6 cm × 10 cm ascending colon carcinoma, causing large intestine obstruction, with simultaneous multiple hepatic metastases and peritoneal carcinomatosis. Surgical resection of the primary tumor was performed, because of the bowel obstruction, to ameliorate the symptoms before the onset of chemotherapy. Histopathology revealed that the tumor was a small-cell undifferentiated NEC. During the post0operative period, the patient presented pulmonary metastases, and on the 36th post-operative day, death occurred due to respiratory failure.

Abstract
The objective of this study was to evaluate the contribution of the medial retinaculum to the stability of the patella, for several angles of knee flexion. For six cadaveric knees, the patella and patella retinaculum were exposed, and the force required to dislocate the patella laterally by 5 mm was measured, in 0, 45 and 90 degrees of knee flexion, preserving and dissecting the medial retinaculum. Wilcoxon singed rank test (SPSS, version 23, Chicago, USA) was used for data analysis. A p value of < 0.05 was considered as statistically significant. The force required to displace the patella laterally is smaller with the medial retinaculum dissected than intact, in 0, 45 and 90 degrees (p = 0.028, p = 0.046, p = 0.027 respectively). The lateral displacement force is greater as the flexion angle increases, with medial retinaculum intact or dissected (p = 0.028). Thus, an intact medial retinaculum provides more stability against lateral displacement forces to the patella, especially in lower flexion angles. Consequently, surgical methods reinforcing the medial retinaculum combined or not with lateral retinaculum release, are of great importance in the plan of the orthopedic surgeons. The engagement of the bones during flexion of the knee contributes significantly to the stability of the patella.

Abstract
BACKGROUND The aim of this study was to analyse the biomechanical role of medial retinaculum, as a stabilising factor against lateral patellar dislocation. MATERIALS AND METHODS This cadaveric-biomechanical study included the patellae of 10 cadaveric knees, which were surgically exposed and the medial retinaculum of each one was located. A stable 24.51 N force was applied to the four parts of the quadriceps, and an increasing lateral displacing force was applied to the patella, up to 5 mm dislocation. The study was repeated for 0o, 45o, and 90o of knee flexion, with the medial retinaculum intact and dissected. The Wilcoxon signed rank test was used for data analysis. A p value < 0.05 was considered as statistical significant. RESULTS After the dissection of medial retinaculum, the lateral displacement force was lower at every angle of knee flexion (p = 0.005, p = 0.007, p = 0.005, respectively). The lateral displacement force increased as the flexion angle increased (p = 0.005), regardless of medial retinaculum integrity. CONCLUSIONS Medial retinaculum acts as a stabilising factor for the patella, against its lateral dislocation in lower flexion angles. Therefore, methods of surgical reinforcement or repair of medial retinaculum could provide protection against recurrent patellar dislocation.

Abstract
Long-standing scapholunate instability frequently leads to progressive deterioration of the adjacent joint cartilages in a consistent repetitive sequence of arthritis. The purpose of this study was to investigate whether the capitate-triquetrum distance is related with the occurrence of carpal collapse in cases of static scapholunate instability. In this retrospective study, 41 patients formed two groups based on the capitate-triquetrum distance; twenty-four with distance of less than 5mm and 17 with distance of 5mm or more. No significant difference was detected with respect to age, sex distribution, dominant hand involvement, initial treatment and time from injury to final x-rays. Three patients (3/24, 12.5%) of the C-T < 5mm group and 10 patients (10/17, 58.8%) of the C-T ≥ 5mm group had no sign of carpal collapse. This difference was statistically significant (p=0.017). Capitate-triquetrum distance could reliably contribute in the decision making process in difficult cases of static scapholunate instability.

Abstract
Myocardial bridging (MB) is considered as a topic of high interest since its occurrence in different studies is statistically significant, and the clinical manifestations of this phenomenon are complicated with cardiovascular diseases. Whether the MB participates in heart diseases and has a decisive effect to life-threatening situations is still under research, and many studies have been conducted to clarify the abovementioned question. A case report with a MB on the left anterior descending coronary artery is presented in the current study, and a review of the literature is provided as well. Cardiologists as well thoracic surgeons and radiologists should bear in their mind the potential presence of such variant during interpretation of angiographies and multidetector-computed tomography.

Abstract
Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) was previously considered a rare, early-onset recessive form of small-vessel disease (SVD) caused by biallelic mutations in the serine protease gene HTRA1 with subsequent loss of its activity. However, very recently, there is growing interest of research showing heterozygous HTRA1 mutations as causes of SVD with a dominant inheritance pattern. This first Greek heterozygous CARASIL case with unusual clinico-radiological presentation extends our very recent knowledge on how heterozygous CARASIL mutations may be associated with cerebral SVD. Our findings highlight heterozygous HTRA1 mutations as an important cause of familial SVD, and that screening of HTRA1 should be considered in all patients with a hereditary SVD of unknown aetiology.

Abstract
In the current cadaveric study an unusual sizeable accessory phrenic nerve (APN) was encountered emerging from the trunk of the supraclavicular nerves and forming a triangular loop that was anastomosing with the phrenic nerve. That neural loop surrounded the superficial cervical artery which displayed a spiral course. The form of a triangular loop of APN involving the aforementioned artery and originating from the supraclavicular nerve to the best of our knowledge has not been documented previously in the literature. The variable morphological features of the APN along with its clinical applications are briefly discussed.

Abstract
OBJECTIVE In the current study a brief review is presented of the coracobrachialis muscle's morphological variability, action, embryological development and clinical significance. CASE REPORT We report a case of a left-sided coracobrachialis muscle consisting of two bellies. The deep belly inserts into the usual site in the middle area of the anteromedial aspect of the left humerus, whereas the superficial belly inserts through a muscular slip into the brachial fascia and the medial intermuscular septum, forming a musculo-aponeurotic tunnel in the middle region of the left arm, for the passage of the median nerve, brachial artery and veins, medial antebrachial cutaneous nerve and ulnar nerve. CONCLUSION Awareness of such a muscle variant should be kept in mind by physicians and surgeons during interpretation of neural and vascular disorders of the upper limb, since such a variant may potentially lead to entrapment neuropathy and/or vascular compression, predisposing to neurovascular disorders, as well as during preparation of that muscle in cases of utilizing it as a graft in reconstruction of defects.

Abstract
A double upper subscapular nerve on the right side was detected in a male cadaver, with the proximal one arising from the suprascapular nerve and the distal one from the posterior division of the upper trunk of the brachial plexus. Both of them penetrated and supplied the uppermost portion of the right subscapularis muscle. That anatomic variation was associated with a median nerve formed by two lateral roots. The origin and pattern of the upper subscapular nerve displays high variability, however the presented combination of the variable origin of a double upper subscapular nerve has rarely been described in the literature. The knowledge of such an anatomic variation is essential for the surgeon operating in the region especially in instances of brachial plexus' repair after any traumatic injury. Moreover, the awareness of the precise origin and topography of these nerves is important for the physician attempting to block these nerves or utilizing these nerves as grafts for neurotization of adjacent damaged nerves of the brachial plexus.

Abstract
Pathologic splenic rupture is defined as the spontaneous rupture of a diseased spleen and is quite rare. It is usually associated with oncologic, infectious, and hematologic diseases and more seldom with other rare causes. Pathologic splenic rupture related to hematologic malignancy seems to be rare with only 136 cases reported from 1861 until 1996 and a few cases thereafter. Non-Hodgkin lymphoma and acute myeloid leukemia are most frequently reported followed by chronic myeloid leukemia and lymphoblastic acute leukemia. However, even in cases of non-Hodgkin lymphoma, pathologic splenic rupture as the presenting symptom of the disease is rare as is the presence of primary splenic lymphoma. Conservative treatment is not an option, while operative intervention and emergency splenectomy is the only feasible treatment. We present a very rare case of pathologic rupture of primary splenic lymphoma which was the presenting symptom of the disease.

Abstract
An unusual combination of median nerve's variations has been encountered in a male cadaver during routine educational dissection. In particular, the median nerve was formed by five roots; three roots originated from the lateral cord of the brachial plexus joined individually the median nerve's medial root. The latter (fourth) root was united with the lateral (fifth) root of the median nerve forming the median nerve distally in the upper arm and not the axilla as usually. In addition, the median nerve was situated medial to the brachial artery. We review comprehensively the relevant variants, their embryologic development and their potential clinical applications.

Abstract
OBJECTIVE To evaluate the correlation between the Manchester Grading Scale and the American Orthopaedic Foot and Ankle Society (AOFAS) score in patients with a hallux valgus deformity. SUBJECTS AND METHODS The study sample included 181 feet of 122 patients with hallux valgus and 424 feet of 212 individuals without hallux valgus deformity as the control group. The severity of hallux valgus, utilizing a relative nonmetric scale, the Manchester Grading Scale, and the metric AOFAS score, was determined for all individuals in the hallux valgus and control groups. SPSS version 18 (Chicago, Ill., USA) was used for data analysis. RESULTS According to the Manchester Grading Scale, the 424 feet of the normal group were classified as 'no deformity'. In the hallux valgus group, 85 feet were classified as 'mild deformity', 67 as 'moderate deformity' and 29 as 'severe deformity'. The AOFAS total score in the control group was 99.14. In the hallux valgus group, patients with mild or moderate deformity had total scores of 86.20 and 68.19, respectively. For those with severe hallux valgus, the total score was 44.69 and the differences were statistically significant (p = 0.000). Using the Pearson correlation, strong negative correlations were found between the AOFAS score and the hallux valgus angle (HVA; r = -0.899, p = 0.000). Strong negative correlations were demonstrated between the AOFAS score and the first intermetatarsal angle (IMA) as well (r = -0.748, p = 0.000). CONCLUSIONS The AOFAS score was negatively associated with the Manchester Grading Scale, HVA and first IMA. As the severity of hallux valgus increased, the AOFAS score seemed to decrease.

Abstract
The current study displays a very rare combination of ossified interclinoid ligaments at the sella turcica region associated with bilateral foramina of Vesalius. In a macerated skull four osseous bars interconnecting the clinoid processes bilaterally were detected. Specifically, two bilateral osseous bars were observed bridging the gap between the anterior and middle clinoid processes forming the so called caroticoclinoid foramen on each side and two additional osseous bridges linked the anterior and posterior clinoid processes, bilaterally. Furthermore, two distinct bilateral foramina of Vesalius were documented just anterior and medial to the foramen ovale. The awareness of the osseous sellar bridges is crucial for the physician and especially the neurosurgeon since their presence may complicate the removal of clinoid processes and induce damage of the internal carotid artery and oculomotor nerves. Furthermore, the likely existence of the foramen of Vesalius may lead to transfer of an infected thrombus into the cranial cavity and complicate a percutaneous trigeminal rhizotomy.

Abstract
Migraine and tension type headache are the two most common primary headaches. The purpose of this study was to detect differences in clinical characteristics and headache triggers and in a Greek cohort of 51 migraineurs and 12 patients with tension-type headache. (TTH) Migraine patients had a significantly lower age at headache onset and frequency, higher mean visual analogue scale (VAS) and greater maximum duration of headache episodes compared to TTH patients. They did not differ from (TTH) patients in quality of headache, laterality of pain, way of headache installation and progression and temporal pattern of headaches. Nausea, vomiting and phonophobia were more frequent in migraine. Triggering of headaches by dietary factors was associated with migraine, whereas there was no difference between the two groups in any of the other headache triggers. Stress, both physical and psychological, were particularly common in both patient groups.

Abstract
BACKGROUND Varicose vein surgery is very commonly performed. Also, it is very frequently employed for recurrent disease. The recognition of the normal or variant veins, inducing incompetency, is a prerequisite for effective treatment. The thigh extension of the small saphenous vein, the so-called Giacomini vein, was extensively described in 1873 by Carlo Giacomini in an incidence of 72%. However, such a vein is usually underestimated in classic surgical textbooks. DESCRIPTION OF CASES We present two cases of Giacomini vein found in two cadavers, dissected for academic purposes in the Department of Anatomy, where the small saphenous vein displayed a thigh extension without terminating into the popliteal vein. In one case Giacomini vein drained into the large saphenous vein, while in the other case the vein divided into two branches, separately draining into the large saphenous vein and the subcutaneous tissue of the gluteal region. CONCLUSION Due to the fact that Giacomini vein could be incompetent, associated with or without varicose saphenous vein trunks, the vascular surgeon should keep in mind that anatomical entity, to include it in preoperative ultrasound scanning control. Moreover, this vein could be utilized as an autologous graft, when the large saphenous is not available. Hippokratia 2015; 19 (3): 263-265.

Abstract
PURPOSE Since numerous surgical procedures in oral and maxillofacial surgery as well as several aspects of dental practice involve the mental region, the knowledge of its anatomical variations is essential for the clinician. Therefore, the aim of the present study was to evaluate the incidence and the anatomical features of the accessory mental foramen, which is occasionally traced additionally to the main mental foramen. MATERIAL AND METHODS Ninety-six dry human mandibles of a Greek population and of unknown sex and age were examined in order to notice the presence of possible accessory mental foramina. The frequency of the accessory mental foramen was calculated, and its dimensions and its topographical relationship to the teeth of the mandible and the mental foramen were determined as well. RESULTS A single accessory mental foramen was identified in 4.17% of the sample, while its mean transverse diameter was measured to be 1.09 mm and its mean distance from the mental foramen was 5.24 mm. CONCLUSIONS The present study revealed an appreciable incidence of the accessory mental foramen in the Greek population, recognizably higher than the discovered incidence of past studies involving the Greek population. Consequently, the clinician should always be prepared to deal with an accessory mental foramen during surgical procedures.

Abstract
Two aberrant rami originating from the right transverse cervical nerve and innervated the midportion of the sternocleidomastoid muscle (SM) were detected during routine cadaver dissection. Although SM is commonly innervated by the accessory nerve, as well as by cervical nerves, it is likely to be innervated additionally by other nerves such as hypoglossal nerve, ansa cervicalis, facial or external laryngeal nerve. Some considerations as regards the possible composition of the aberrant rami of the transverse cervical nerve detected in the current study, as well as the relevant literature is discussed.

Abstract
OBJECTIVE The aim of this study was to evaluate the correlation between the Manchester scale and foot pressure distribution in patients with hallux valgus deformity. METHODS The study included 152 feet of 87 patients with hallux valgus and a control group of 391 feet of 241 individuals without hallux valgus deformity. The severity of hallux valgus was determined using the Manchester scale grading system. Plantar loading patterns in 10 foot areas were determined for all participants. RESULTS According to the Manchester scale, 72% of the participants had no, 12.9% mild, 10.7% moderate and 4.4% severe deformity. The Manchester scale grade was highly correlated with both hallux valgus angle and first intermetatarsal angle (p=0.00). Significant differences between the four grades were present for mean pressure under the hallux and the first and second metatarsal heads only (p=0.00). The load distribution under these areas was higher as the hallux valgus progressed from mild to more severe. In all groups, the highest pressure was observed under the second metatarsal head. CONCLUSION The Manchester scale was strongly associated with both the hallux valgus angle and the first intermetatarsal angle. The progression from mild to moderate and severe deformation is associated with peak pressure raise at the hallux, first and second metatarsal heads. The Manchester scale appears to be a useful tool to provide information for the degree of deformity and the pressure under painful foot areas.

Abstract
The effect of the lunate type on carpal collapse in cases of scaphoid nonunion has not been thoroughly investigated. The purpose of the present study was to determine whether any association exists or not between the capitate-triquetrum distance and occurrence of carpal collapse in cases of scaphoid nonunion. In a retrospective study, 76 patients with scaphoid nonunion formed two groups based on the capitate-triquetrum distance: forty-three patients with distance of less than 5 mm and 33 patients with distance of 5 mm or more. The two groups were comparable with respect to sex distribution, age, dominant hand involvement, manual labor, nonunion location and time from injury to final x-rays. Six patients (13.9%) in the capitate-triquetrum<5 mm group and 13 patients (39.4%) in the capitate-triquetrum≥5 mm group had no signs of collapse, with significant difference (p<0.05). Capitate-triquetrum distance could contribute in the decision making process for cases of scaphoid nonunion without straightforward indication for surgical intervention.

Abstract
Entrapment of the superficial peroneal nerve is an uncommon neuropathy that may occur because of mechanical compression of the nerve, usually at its exit from the crural fascia. The symptoms include sensory alterations over the distribution area of the superficial peroneal nerve. Clinical examination, electrophysiologic findings, and imaging techniques can establish the diagnosis. Variations in the superficial peroneal sensory innervation over the dorsum of the foot may lead to variable results during neurologic examination and variable symptomatology in patients with nerve entrapment or lesions. Knowledge of the nerve's anatomy at the lower leg, foot, and ankle is of essential significance for the neurologist and surgeon intervening in the area.
