RESUMEN
BACKGROUND: Esophageal surgery has always been considered extremely demanding, given the surgical experience and skills required, due to the anatomic location of the esophagus as well as the impact of such extensive operations on patients' homeostasis. The intention of the present study is to review all historical time points of esophageal surgery, from its inception to the modern era of minimally invasive esophageal surgery. METHODS: The first clear description of esophageal surgery is dated back to 1738, in an attempt to remove a foreign body from the thoracic esophagus. However, the high morbidity and mortality rates of esophageal surgical operations led to the invention and application of less invasive surgical procedures. RESULTS: Esophageal surgery has evolved from extensive surgical operations to minimally invasive esophagectomies, aiming exclusively to reduce perioperative morbidity and mortality, while maintaining surgical effectiveness. Despite the fact that benign esophageal pathologies were the main stimulus for this evolution, minimally invasive esophageal surgery is now applied even in patients with esophageal cancer, with outcomes comparable to those of traditional surgical approaches. CONCLUSION: It would be interesting to see how all these new surgical techniques may evolve, altering further the current status of esophageal surgery in the future.

Colorectal cancer represents a leading cause of cancer-related morbidity and mortality. Despite improvements, chemotherapy remains the backbone of colorectal cancer treatment. The aim of this study is to investigate the variation of circulating microRNA expression profiles and the response to irinotecan-based treatment in metastatic colorectal cancer and to identify relevant target genes and molecular functions. Serum samples from 95 metastatic colorectal cancer patients were analyzed. The microRNA expression was tested with a NucleoSpin miRNA kit (Machnery-Nagel, Germany), and a machine learning approach was subsequently applied for microRNA profiling. The top 10 upregulated microRNAs in the non-responders group were hsa-miR-181b-5p, hsa-miR-10b-5p, hsa-let-7f-5p, hsa-miR-181a-5p, hsa-miR-181d-5p, hsa-miR-301a-3p, hsa-miR-92a-3p, hsa-miR-155-5p, hsa-miR-30c-5p, and hsa-let-7i-5p. Similarly, the top 10 downregulated microRNAs were hsa-let-7d-5p, hsa-let-7c-5p, hsa-miR-215-5p, hsa-miR-143-3p, hsa-let-7a-5p, hsa-miR-10a-5p, hsa-miR-142-5p, hsa-miR-148a-3p, hsa-miR-122-5p, and hsa-miR-17-5p. The upregulation of microRNAs in the miR-181 family and the downregulation of those in the let-7 family appear to be mostly involved with non-responsiveness to irinotecan-based treatment.

PURPOSE: New training methods sprung up using communication technologies after the suspension imposed on Greek Universities due to restrictive measures against the COVID-19 pandemic. The current questionnaire-based study evaluates the efficacy and utility of the interactive online anatomy labs (ONALs) in assisting the assimilation of anatomy and substituting dissection labs during the pandemic. METHODS: ONALs consisting of video recorded demonstrations of dissected cadavers were developed so that real-time dialogue and interaction between tutor and students was feasible. First- and second-year medical students who were taught neuroanatomy and splanchnology and first-year dental students who were taught head and neck anatomy evaluated the ONALs. RESULTS: One hundred and sixty students participated. The 61 students (38.13%) attended the splanchnology, 58 (36.25%) the neuroanatomy, and 41 (25.63%) the head and neck anatomy course. 86.9% of the participants found the ONALs beneficial for their study. The 75.5% with previous experience of a "face-to-face" dissection replied that the ONALs cannot substitute satisfactorily "face-to-face" dissections. 63.8% replied positively to the ONALs maintenance after the pandemic. CONCLUSIONS: The study's novelty is based on the maintenance of the greater possible interaction between tutors and students during the ONALs, in contrast to the previously described usage of dissection educational videos in anatomy. Our findings reinforce the established statement that "a teaching dissection is an irreplaceable tool in anatomy education". However, the ONALs were well-received by the students and can be kept on as a supplementary teaching modality and can be proven quite useful in Medical Schools that lack cadavers.

BACKGROUND: Tailgut cysts (TGCs) are benign congenital abnormalities that usually present with non-specific symptoms, constituting a diagnostic dilemma for physicians. The aim of this study was to systematically review the literature concerning clinical manifestations, diagnostic modalities and histologic findings of TGCs and highlight current knowledge on therapeutic management of this rare entity. METHODS: PubMed and Embase databases were systematically searched by two independent investigators (last search 18 February 2021) for studies concerning TGCs published in the past two decades. RESULTS: Totally, 144 articles, including 135 case reports and 9 case series, met our inclusion criteria. One hundred eighty-four patients were included (3:1/female:male) with an age of 42.3 ± 18.7 years (mean, SD), while 5 cases concerned new-born infants. Pain was the prevailing clinical manifestation (41.8%), whereas 16.8% were asymptomatic. MRI and CT were utilized for diagnosis in 58.7% and 54.7% of cases, respectively. The majority of cysts were multilocular, while ciliated columnar epithelium and smooth muscles of the cyst wall were the prevailed histological findings. Malignant degeneration of TGCs was reported in 32.1% of cases, while carcinoid tumours were the most frequent malignancies. Surgical resection was performed in 155 cases, while laparoscopic and robotic approach was preferred in 18 and 2 cases, respectively. A posterior approach was implemented in 80.9%, anterior technique in 9% and combined technique in 6.7% of cases. Postoperative complications and recurrence of the cystic lesion were reported in 17.4% and 7.6% of cases, respectively. CONCLUSIONS: TGCs constitute a dilemma for the physicians. Surgical resection comprises the ultimate treatment to avoid complications or malignant transformation of the cyst. Concrete follow-up strategies and optimal therapeutic options should be outlined through consensus guidelines and at the time being, such decisions can be made only on the basis of extrapolation and on a case-by-case approach.

Edward Delos Churchill, one of the most notorious American surgeons of the 20th century, influenced countless surgeons and set medical practices that were used for decades. His scope of interests included surgery of the lungs, heart, thyroid, parathyroid glands, and military surgery among others. Churchill was one of the first to expand the field of the newly found parathyroid bodies by performing several experimental excisions of the glands and publishing numerous guidelines based on his innovative work. Additionally, he aspired to address many of the literature gaps that led him to conclusions that would benefit both the surgeons and patients throughout the country. Most importantly, his deep interest in endocrinology and his aggregate approach of medicine led him to discoveries that paved the way to the modern endocrine surgery practices.

Sir William Arbuthnot Lane (1856-1943) is considered a pioneer in orthopedic surgery, especially for his breakthrough for the time technique for bone and mainly femoral surgery, the so-called screw and plates technique, which was also accompanied by his aseptic surgical approach. Apart from his innovations in colon, nose, ear, throat, and reconstructive surgery, his treatises on orthopedic surgery were considered as masterpieces. Femoral anatomy and surgical anatomy attracted mainly his interest as seen in his treatises.

Johann Friedrich Horner is remembered in ophthalmology due to his brief report in the German scientific journal 'Klinische Monatsblatter fur Augenheilkunde', in which emphasized the clinical value of a cluster of external signs of damage to the cervical sympathetic nerve. Although J .F .Horner was not the first to describe such a syndrome, he was credited with the nomination. For the French, Francois Pourfour du Petit was the pioneer in that case. Born in Zurich, travelled Europe to be further educated, becoming later on Professor and Director of the University Clinic of Ophthalmology in his native city. In conclusion, J .F .Horner's adamantine character, hard work, assiduous teaching and skills in eye surgery made him one of the main contributors for the evolution of ophthalmology in the nineteenth century Central Europe.

Aromatase inhibitors (AIs) are widely used as adjuvant hormonal therapy in postmenopausal women with hormone receptor-positive breast cancer. The purpose of this study was to investigate the potential impact of AIs on the anterior segment of the eye and especially the ocular surface. Participants in our study were 41 hormone receptor-positive early stage breast cancer patients (80 eyes), treated with AIs, while 80 eyes of 40 age- and gender-matched healthy controls, not previously used AIs for any purpose, were also evaluated. All participants underwent a complete ophthalmological examination, including best corrected visual acuity (BCVA) assessment, slit-lamp biomicroscopy, and dilated fundus examination. Ocular surface disease-related symptoms and signs were also recorded. The most common symptom was found to be blurred vision, while other symptoms included foreign body sensation, tearing, redness, and photophobia. Slit-lamp examination revealed blepharitis and meibomian gland dysfunction in 75% and 42.5% of patients, respectively. Superficial punctate keratitis and conjunctival injection were also present. Our results demonstrated a high prevalence of ocular surface disease-related symptoms and signs in patients receiving AIs compared to healthy controls. This study may raise a flag regarding the use of AIs. However, further and larger prospective longitudinal studies are needed to examine the possible effect of AIs alone or in combination with chemotherapy in the eyes of breast cancer patients.

BACKGROUND: The present cross-sectional study has the purpose to investigate the impact of aromatase inhibitors (AIs) on retinal nerve fiber layer (RNFL) thickness, optic nerve and macular function in patients using AIs for breast cancer treatment. METHODS: Participants in our study were 41 hormone-receptor-positive earlystage breast cancer patients who were treated with AIs in the adjuvant setting. Moreover, 40 age- and gender-matched control subjects, having neither ocular nor systemic disorders, were included in this study. All participants underwent a complete ophthalmological examination, including best corrected visual acuity (BCVA) assessment, RNFL thickness and central foveal thickness (CFT) measurement, visual evoked potentials (VEP) recording and multifocal-electroretinogram (mf-ERG) recording. Univariate and multiple regression analyses were performed. RESULTS: At the multiple regression analyses, patients receiving AIs presented with lower average RNFL and inferior RNFL. Moreover, similarly to the univariate analysis, intake of AIs was associated with lower amplitude P100, lower retinal response density in ring 1 and ring 2, longer peak time P100 and longer P1 time in ring 1. CONCLUSION: Our study is the first in the literature investigating the potential effect of AIs on RNFL thickness, optic nerve and macular function in patients using AIs for breast cancer treatment. The principal message of our study is that patients using AIs exhibited a significant decrease in RNFL thickness (average, superior and inferior), retinal response density and visual acuity compared to healthy controls, while VEP findings (both amplitude and peak time of P100) differ significantly as well.

Male breast cancer is an uncommon malignancy; little is known regarding hormonal manipulations for tamoxifen-resistant male breast cancer patients. This is the first pooled analysis of the literature to synthesize all available data and to evaluate the efficacy and safety of fulvestrant in male breast cancer. This study was performed in accordance with the PRISMA guidelines. All studies that examined the efficacy of fulvestrant in male breast cancer, regardless of sample size, were considered eligible. The search strategy retrieved 31 articles; of these, five articles were eligible (23 patients) for this pooled analysis. The mean age of the study sample was 63.1 years. Adjuvant hormonal treatment was administered in 87.5 % of cases. Fulvestrant was given as first or second line in 40 % of patients, while as third line or beyond in 60 % of patients. 79.0 % of patients at fulvestrant administration had visceral metastases. Regarding best response, in 26.1 % PR was achieved, in 47.8 % of cases SD was recorded, whereas in 26.1 % of patients PD was noted. The median PFS was equal to 5 months. No grade 3 and 4 adverse events were recorded; of note, hot flashes were reported in 18.2 % of male breast cancer patients. Fulvestrant may potentially play a promising role in the optimal therapeutic strategy for male patients with breast cancer diagnosis. However, further clinical and pharmacokinetic investigations are more than warranted before fulvestrant use becomes a common practice in male breast cancer patients.

Although several studies have shown the efficacy of third-generation aromatase inhibitors (AIs) in women with breast cancer, the role of such molecules remains elusive in male breast cancer patients. It is also unknown whether the addition of gonadotropin-releasing hormone (GnRH) analogues to AIs would be a superior strategy or not. This pooled analysis was conducted in accordance with the PRISMA guidelines. All studies that examined the efficacy of AIs in metastatic male breast cancer were considered eligible. Overall, 15 studies (105 cases) were eligible for this pooled analysis. The mean age of the study sample was 62.8 years. ER status was positive in all eligible cases. AI was given as first line in 61.5 % of cases. GnRH analogue was co-administered with AI in 37.1 % of cases (n = 39). CR, PR, SD and PD were achieved in 5.7, 23.8, 37.2 and 33.3 % of cases, respectively. The median PFS and OS were equal to 10.0 and 39.0 months, respectively. Co-administration of GnRH analogues was associated with more than threefold increase in rates of clinical benefit (OR = 3.37, 95 % CI 1.30-8.73) but did not seem to correlate with better PFS or OS. No statistically significant associations between the examined outcomes and the other parameters were noted. Available data suggest that AIs may potentially play a promising role in the optimal therapeutic strategy for metastatic male breast cancer patients. Especially, co-administration of AI with a GnRH analogue seems to increase the rate of clinical benefit and could be more effective, warranting further consideration.

CONTEXT: The potential of lazaroid U-74389G in attenuating injury after ischemia and reperfusion has been reported in various organs. OBJECTIVE: The present study focuses specifically on the pancreas and aims to examine any effects of U-74389G in a swine model of pancreatic ischemia and reperfusion, encompassing ischemic preconditioning. METHODS: Twelve pigs, weighing 28-35 kg, were randomized into two experimental groups. Group A (control group, n=6): Two periods of ischemic preconditioning (5 min each) separated by a 5-min rest interval; then ischemia time 30 min and reperfusion for 120 min. Group B (n=6): the same as above, with U-74389G intravenous injection in the inferior vena cava immediately prior to the initiation of reperfusion. Blood sampling and pancreatic biopsies were conducted at 0, 30, 60, 90 and 120 min after reperfusion. RESULTS: Repeated-measures ANOVA was undertaken to evaluate differences between the two study groups. No statistically significant differences were noted concerning the histopathological parameters in the control and therapy groups (P=0.563 for edema, P=0.241 for hemorrhage, P=0.256 for leukocyte infiltration, P=0.231 for acinar necrosis and P=0.438 for vacuolization). In accordance with the above, serum metabolic data (glucose, creatinine, urea, total and direct bilirubin, total calcium, amylase, lipase, SGOT/AST, SGPT/ALT, ALP, GGT, LDH, CRP, insulin) were not significantly different between the two groups; similarly, tumor necrosis factor-α values (P=0.705) and tissue malondialdehyde levels (P=0.628) did not differ between the two groups. CONCLUSION: This swine model of pancreatic ischemia and reperfusion, encompassing preconditioning, indicates that U-74389G lazaroid does not seem to exert protective effects from pancreatic damage.
RESUMEN
BACKGROUND: Oxidative stress is a crucial factor in the pathophysiology of acute pancreatitis and its systemic complications. Lazaroids are a novel class of antioxidants that potently protect pancreatic acinar cells against oxidant attack. The aim of our study was to evaluate the therapeutic potential of 21-aminosteroid U-74389G in pancreatic injury after ischemia and reperfusion of the organ in a swine model. MATERIALS AND METHODS: Twelve pigs (weighing 28-35 kg) were randomized into the following two experimental groups: group A (control group, n = 6): ischemia of pancreas (30 min) followed by reperfusion for 120 min; and group B (n = 6): ischemia of pancreas (30 min), U-74389G intravenous injection (10 mg/kg) in the inferior vena cava, and reperfusion for 120 min. Tissue and blood sampling was conducted at 0, 30, 60, 90 and 120 min after reperfusion. Repeated measures analysis of variance was performed for the evaluation of differences between the two groups. RESULTS: Histopathologic evaluation did not reveal a statistically significant difference concerning hemorrhage (P = 0.193), leukocyte infiltration (P = 0.838), acinar necrosis (P = 0.183), and vacuolization (P = 0.185) in the pancreatic tissue between the two groups; nevertheless, edema seemed to be more pronounced in the U-74389G group (P = 0.020). Serum metabolic data in the control and therapy groups were not significantly different; accordingly, tissue malondialdehyde levels (P = 0.705) and tumor necrosis factor α values (P = 0.863) did not differ between the two groups. CONCLUSIONS: On the basis of the histologic data and the absence of reduction in the malondialdehyde and tumor necrosis factor α levels, it is concluded that the administration of U-74389G does not seem to exert a sizable therapeutic effect in attenuating pancreatic damage from ischemia-reperfusion injury.

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.

Patellofemoral instability is a complex pathology with multiple risk factors, which affects mostly young females and may avert them from both activities of daily living and sports participation. Risk factors for instability include patella alta, trochlea dysplasia, abnormal lateral patellar tilt, and increased tibial tuberosity-trochlea groove distance. The knowledge of these anatomical abnormalities is the key to identifying the problem and succeeding in treating the patients.
RESUMEN
Patellofemoral instability (PFI) is a common condition in children and adolescents, ranging from mild discomfort and mal-tracking to lateral patellar dislocation [1]. A number of anatomical risk factors have been described in the literature, such as trochlear dysplasia, patella alta, excessive tibial tuberosity to trochlear groove (TT-TG) distance, patellar tilt and soft tissue alterations [2]. Among them, TD has been identified as the main anatomical risk factor with the strongest association with PFI [1, 2]. In the study by Dejour et al. [2] radiographically observed TD was identified in 96% of patients with a history of patellofemoral dislocation [1, 2]. Patients with Dejour Type D dysplasia are characterized by a prominent and convex lateral facet with a vertical connection to a hypoplastic medial facet (Figure 1), which provides inadequate tracking of the patella in the trochlea during flexion leading to patella subluxation [2]. Non-operative treatment of lateral patellar dislocation presents a rate of re-dislocation up to 70% within 24 months of the first episode [3]. Sulcus deepening trochleoplasty is indicated for Type B and D dysplasia, in order to improve patella tracking, reduce the rate of re-dislocation and achieve good functional outcomes [2, 4]. Trochlea dysplasia is defined as a shallow or flattened groove with decreased resistance to lateral patellar translation. TD can be assessed on computed tomography (CT) and magnetic resonance imaging (MRI) with the use of overlapping axial images and are able to show perfectly the global shape of the femoral trochlea [2]. The thresholds for identifying trochlear dysplasia are established based on the sulcus angle ≥ 145°, medial/lateral trochlea facet asymmetry < 40%, trochlear depth < 3 mm and lateral trochlear inclination ≤ 11° and therefore it can be used in young adolescents [4, 5]. A deep knowledge of anatomic variations and abnormalities of the patellofemoral joint, which may predispose to PFI, is crucial in order to choose the appropriate treatment for each patient.

OBJECTIVE: The subscapular artery vascularizes a substantial region of the thoracic wall, and the significance of its distribution is well depicted in the diversity of reconstructive procedures that rely on its blood supply. The aim of this study is to present an uncommon anatomical variation of the artery and discuss the clinical implications of its presence. CASE REPORT: This case report depicts a rare variant of compression and the kinking of the subscapular artery by the radial nerve on the posterior wall of the axilla that was encountered during dissection of a male cadaver of Greek origin. CONCLUSION: The use of autologous tissues in the reconstruction of defects and treatment of lymphedema is expanding, so the need to establish safer surgical dissections is also becoming more apparent. The case of entrapment of the subscapular artery by the radial nerve is extremely rare, however, utilizing tissues perfused by this artery for reconstructive purposes could potentially be futile and unsuccessful due to the inadequate blood supply or vessel thrombosis. Hence, the surgeon should adapt the treatment plan according to preoperative findings, as the presence of anatomical variants should always be suspected.
RESUMEN
OBJECTIVE: The objective of this paper is to present and document a specific case of breast reconstruction using an adapted Type IV Keystone Flap technique, with a droplet-shaped design with a reduced flap ratio, and to identify the qualities of this method. CASE REPORT: A 41-year-old woman, with a history of myocardial infarction and low ejection fraction, underwent a lumpectomy, resulting in a lower medial quadrant deficit in her left breast. After she developed skin and tissue necrosis and infection, implementing the Type IV Keystone Flap effectively addressed the deficit, ensuring sufficient coverage. The flap extended dropwise beneath the deficit, progressing anteriorly towards the upper rectus abdominis, with a ratio of 2.5:1. The flap's novel droplet shape allowed for the utilization of fewer perforators, while ensuring adequate blood supply and tissue coverage, leading to improved perfusion and aesthetic outcome. CONCLUSION: The application of the adapted Type IV Keystone Flap highlights its capacity as a versatile and effective method for breast reconstruction post-lumpectomy. With the advantages of a short learning curve, easy execution, and acceptable risk profile, it offers a valuable alternative for patients who may not be suitable for more complex surgeries. Further research is recommended to confirm its broader applicability and to conduct a comparative analysis with other techniques.
RESUMEN
The purpose of this article is to present a well-known physician and highlight his contribution into an essential, but neglected anatomical feature. George Sclavunos (1869-1954) was a 20th century Greek physician, whose scientific work was a significant milestone in global medical knowledge. In 1899 he became Professor of Anatomy and Head Director of the Department of Anatomy. In 1906 Sclavunos G. published the first volume of the three volume book "Human Anatomy" (1906-1926), which is characterized by its unparalleled illustrations. For more than a century it was the most important book of medical literature in Greece. In 1926 he became a Full Member of the Academy of Athens and was named Life Partner of the International Anatomical Society. His interests included Anatomy, Physiology, Histology, as well as Osteology and Syndesmology. In his book "Human Anatomy", he described for first time the "Sialine Groove of the Stomach", which was described by Waldeyer-Hartz almost at the same time as the "Magenstrasse", a German word that means "stomach road". It is a ribbon-like path that extends along the lesser curvature of the stomach from the gastric cardia to the antrum and releases the gastric content directly into the small intestine. Its importance is confirmed by its association not only with drug delivery, but also with anti-obesity surgical techniques. The old German term has come back into common medical usage in view of the commonly performed Magenstrasse and Mill procedure, a form of bariatric surgery. CONCLUSION: Sclavunos G. managed to observe an anatomical structure that has remained of great importance until today.

OBJECTIVE: The external jugular vein drains a considerable part of the head and neck and constitutes a vessel implicated in various procedures in the cervical region. The aim of this study is to present an uncommon anatomical variation of the external jugular vein, and discuss the clinical implications of its presence. CASE REPORT: We present a rare case of an ectopic external jugular vein terminating into the axillary vein, that we came across during routine dissection of a male cadaver of Greek origin. CONCLUSION: The venous system of the external jugular vein is used during procedures for the treatment of various conditions such as cardiac arrhythmias, hydrocephalus and defects of the head and neck. Hence, encountering the unpredictable course of a variant draining into the axillary vein may complicate these interventions, leading to multiple manipulations and undesirable results. Surgeons should be aware of the alternate anatomy of the venous system of the cervical region, and mindful of the possibility of encountering them.
