Abstract
The pterygoid hamulus is a bony process that protrudes from the medial pterygoid plate of the sphenoid bone. In spite of its small size and fragile structure, the pterygoid hamulus is an important anatomical structure in many clinical aspects. Orofacial pain may be related to inflammation or irritation of the pterygoid hamulus; if not, other possible explanations should be explored. In addition, the pterygoid hamulus is an important landmark in the oral cavity and is utilized in a number of dental and medical procedures. Thus, the purpose of this work was to review recent studies demonstrating the role and significance of the pterygoid hamulus in clinical practice.

Abstract
The aim of this paper is to present our experience in transabdominal ultrasonography of ileocecal valve lesions. The ileocecal valve, located in the central part of the ileocecal bowel segment, is rarely the primary site of disease processes. It is usually involved by pathologies in adjacent bowel segments. These are primarily infectious diseases such as yersiniosis, campylobacteriosis and salmonellosis. Typical location of Crohn's lesions also promotes valve involvement. The appearance of the lesions in these cases is characterized by a symmetrical submucosal thickening of the bowel involved over a longer segment. Non-malignant valvular hyperplasia is relatively commonly identified as lipomatosis, manifested by symmetrical enlargement and smooth outlines. However, valvular lipoma causing an asymmetrical hyperechoic bulge is a rare finding. ileocecal valve lipomatosis or lipoma should not be misdiagnosed as a lipoma of the cecoascending part of the colon and, the other way round, a right colonic lipoma should not be mistaken for a fatty valve. Polyps on the ileocecal valve, although sometimes detected, were not identified in our material. Adenocarcinoma, which is found in the cecum in approximately ¼ of cases, is the most common malignancy, followed by neuroendocrine tumor and, rarely, lymphoma. In three cases of malignant involvement of the ileocecal valve, we observed irregular hypoechoic thickening with complete loss of wall stratification, with the lesions causing symptoms of small bowel obstruction in two of these cases. The nearly forgotten ileocecal valve syndrome, also known as Bauhin's ileocecal valve syndrome, characterized by intermittent right iliac fossa pain, is also briefly discussed. Transabdominal ultrasound can be used as an initial diagnostic tool in some of these pathologies.

Abstract
The ileocecal valve is a part of the gastrointestinal tract that separates two intestinal segments differing in both anatomy and function. Dysfunction or surgical removal of the valve usually results in the development of small intestinal bacterial overgrowth syndrome. The available literature lacks a broader discussion and ultrasound presentation of the ileocecal valve. The aim of this study is to present our experience in transabdominal ultrasound of the ileocecal valve in comparison with colonoscopic and computed tomography colonography data. In this part of the manuscript, we discuss the anatomical structures in the right iliac fossa that make up the ileocecal segment of the intestine. The ileocecal valve, which comes in two morphological forms: labial and papillary, is its central part. As shown in computed tomography colonography, the first type is more common, accounting for 76%, the second type accounts for 21%, whereas ileocecal valve lipomatosis is found in 3% of cases. Post-mortem studies have shown a significantly higher incidence of valve lipomatosis, which was found in up to 4 out of 5 cases. Our observations correspond with these findings. Ileocecal valve lipomatosis presents on ultrasound as a hyperechoic, well-circumscribed lesion, with no evident vascularity on color Doppler. This image should be differentiated especially from a lipoma, a relatively common large intestinal pathology. The paper presents two methods of preparation for an ultrasound scan (i.e. only on an empty stomach or after cleansing the intestine) and determines the optimal imaging methods for the ileocecal valve using transabdominal ultrasound. At the end of the ileocecal examination, it should be remembered to assess the lymph nodes in the right iliac fossa.

Abstract
BACKGROUND The annular pancreas (AP) is a rare gastrointestinal congenital malformation, in which malrotation of the pancreatic ventral bud in the seventh week of embryonic development manifests in a partial or complete ring of tissue around the second part of the duodenum. METHODS The main online medical databases such as PubMed, ScienceDirect, Wiley online library, Web of Science, and EBSCO discovery service were used to gather all relevant studies on the AP. RESULTS A total of 12,729,118 patients were analyzed in relation to the prevalence of AP. The pooled prevalence of AP was 0.0045% (95% CI: 0.0021%-0.0077%). The most frequent comorbidity in adults and children was duodenal obstruction, with a pooled prevalence of 24.04% and 52.58%, respectively (95% CI: 6.86%-46.48% and 35.56%-69.31%, respectively). The most frequent operation in adult patients with AP was duodenojejunostomy, with pooled prevalence established at 3.62% (95% CI: 0.00%-10.74%). CONCLUSION The diagnostic complexity of AP is accentuated by its nonspecific clinical symptoms, making accurate identification reliant on imaging studies. Therefore, having a thorough knowledge of the clinical characteristics of the AP and its associated anomalies becomes paramount when faced with this rare congenital condition.

Abstract
The paper presents an anatomical study involving rare variations in the pterygospinous bridges found in Mongolian skulls. These structures extend between the lateral pterygoid plate and the sphenoid spine. Particularly interesting is the division of these bridges into two distinct parts of the similar length. The junctions within these structures resemble morphological patterns characteristic for the plain and zigzag sutures, which articulate the cranial bones.

Abstract
The clinical issues related to the anatomical variation of the mandibular canal have been extensively analyzed since the 19th century. Evolving dentistry techniques and advancements in the prosthetics forced to collect detailed information about anatomical variations of the mandibular canal due to its neurovascular content. Therefore, its radiographic imaging became an essential part of the oral surgery, in order to avoid complications resulted from an accidental damage of the mandibular canal.

Abstract
The objective of the present meta-analysis was to evaluate recent and applicable data regarding the location and variation of the atrioventricular nodal artery (AVNA) in relation to adjacent structures. In order to minimize postoperative risks and maintain physiological anastomosis for proper cardiac function, understanding such possible variations of vascularization of the AV node is of immense importance prior to cardiothoracic surgery as well as ablations. In order to perform this meta-analysis, a systematic search was conducted in which all articles regarding, or at least mentioning, the anatomy of the AVNA was searched. In general, the results were based on 3919 patients. AVNA was found to originate only from the RCA in 82.41% (95% CI: 79.46%-85.18%). The pooled prevalence of AVNA originating only from LCA was found to be 15.25% (95% CI: 12.71%-17.97%). The mean length of AVNA was found to be 22.64 mm (SE = 1.60). The mean maximal diameter of AVNA at its origin was found to be 1.40 mm (SE = 0.14). In conclusion, we believe that this is the most accurate and up-to-date study regarding the highly variable anatomy of the AVNA. The AVNA was found to originate most commonly from the RCA (82.41%). Furthermore, the AVNA was found to most commonly have no (52.46%) or only one branch (33.74%). It is hoped that the results of the present meta-analysis will be helpful for physicians performing cardiothoracic or ablation procedures.

Abstract
INTRODUCTION Osteoporosis affects over 200 million people worldwide causing nearly 9 million fractures annually, with more than half in America and Europe. OBJECTIVES This meta-analysis was conducted to investigate whether low milk intake is associated with an increased risk of fractures by summarizing all the available evidence. METHODS Relevant studies were identified by searching the PubMed and EMBASE databases up to June 2020. The pooled relative risks with 95% confidence intervals were calculated. RESULTS In a meta-regression analysis of 20 included studies (11 cohort and 9 case-control studies), a higher milk intake was not associated with a reduction in the total fracture risk in both sexes (OR 0.95, 95% CI: 0.84- 1.08), either in cohort (OR 0.91; 95% CI: 0.79-1.05) or case-control studies (OR 1.09; 95% CI: 0.82-1.44), as well as separately in men (OR 0.87; 95% CI: 0.71-1.07) and women (OR 0.95; 95% CI: 0.80-1.13). CONCLUSION Higher milk consumption is not associated with fracture risk reduction and should not be recommended for fracture prevention.

Abstract
BACKGROUND In cardiac resynchronization therapy, the coronary venous system is used for left ventricular pacing electrode placement. Despite the well-known anatomy of the coronary sinus and its tributaries, heart failure patients' remodeled and enlarged left ventricles may impede the successful lead placement because of acquired anatomical obstacles. MATERIALS AND METHODS Fifty-five patients qualified for cardiac resynchronization therapy treatment (CRT) were divided into ischemic and non-ischemic cardiomyopathy. Forty-four control groups without heart failure underwent dual-source computed tomography (CT). Rendered reconstructions of cardiac coronary systems were compared. RESULTS The presence of main tributaries was comparable in all groups. The left marginal vein, small cardiac vein, and oblique vein of the left atrium were present in 63%, 60%, and 51% of the hearts in all the groups. CRT referred CT's had significantly longer distances between posterior and lateral cardiac veins over the left ventricle (p < 0.05), wider angles of tributaries (p = 0.03), and smaller lumen of coronary sinus (p = 0.03). In the non-ischemic group, the posterior interventricular and great cardiac veins are more extensive than in the control group. Age-related analysis of vessel size shows a moderate correlation between age and diminishing mean vessel size in all the groups studied. CONCLUSIONS The general structure of the coronary heart system is consistent in patients with and without heart failure. The variance of the general structure, or the presence of adequate veins, is an individual variation. The use of CT and analysis of the coronary veins allow better planning of the CRT-D implantation procedure and may reduce the risk of ineffective left ventricular electrode implantation.

Abstract
Three-dimensional (3D) printed model of the renal vasculature shows a high level of accuracy of subsequent divisions of both the arterial and the venous tree. However, minor artifacts appeared in the form of oval endings to the terminal branches of the vascular tree, contrary to the anticipated sharply pointed segments. Unfortunately, selective laser sintering process does not currently permit to present the arterial, venous and urinary systems in distinct colors, hence topographic relationship between the vascular and the pelvicalyceal systems is difficult to attain. Nonetheless, the 3D printed model can be used for educational purposes to demonstrate the vast renal vasculature and may also serve as a reference model whilst evaluating morphological anomalies of the intrarenal vasculature in a surgical setting.

Abstract
PURPOSE The aims of this paper are to describe the morphological alterations within an infant craniofacial skeleton caused by an orbital tumor and present how the bone reacts in contact with a spreading tumor mass. METHODS A study was performed on the dry skull of a child at the age of approximately 2 years. Morphological alterations of the craniofacial skeleton were analysed by visual inspection, and the intracranial cavity was examined with the aid of a digital camera. Subsequently, the skull was examined using computed tomography. RESULTS The skull was identified as having unilateral symptoms of orbital destruction caused by a malignant tumor, probably retinoblastoma or rhabdomyosarcoma. The left orbit and surrounding bones showed extensive malformation caused by the invading tumor. Profound deformities were also observed in the nasal cavity, which was partially occluded by the collapsed medial wall of the left orbit. The tumor extended to the wall of the orbit, spread out of the orbit, penetrated to the anterior cranial fossa, and probably invaded the brain. CONCLUSIONS Extensive pathological cranial destruction and possible metastases to inner organs suggest that the orbital tumor was the cause of death. Anatomical alterations observed in the craniofacial skeleton indicate a highly aggressive character of the orbital tumor.

Abstract
BACKGROUND AND AIM OF THE STUDY The study aim was to develop an in-vitro model of human aortic valve homograft (AVH) mineralization, as a basis for further research on the subject of calcific aortic valve disease (CAVD). METHODS Human aortic valves were excised during autopsy (12-24 h post-mortem) from donors who had died due to accident or suicide. The mean (±SD) donor age was 32.5 ± 11.4 years. Under sterile conditions each aortic cusp (three cusps per valve) was cut in half to provide a total of 240 tissue samples. AVH mineralization was assessed in solutions with different Ca and P concentrations and CaxPO4 ionic product values. The impact of time on aortic valve mineralization rate was assessed using energy-dispersive X-ray fluorescence (ED-XRF). RESULTS The model showed that human AVH mineralization can be best observed in a solution with a CaxPO4 ionic product of 2.2 mmol2/l2. The optimum incubation time for observing AVH mineralization was 21 days. CONCLUSION A novel in-vitro AVH mineralization model was developed for use in future studies.

Abstract
BACKGROUND AND THE AIM OF THE STUDY A major feature of aortic stenosis is massive mineralization of the aortic valve, though the mechanism of the process remains unclear. The study aim was to characterize the chemical composition and morphology of inorganic deposits from surgically excised natural aortic valves and to seek similarities to minerals in bones and teeth. METHODS Mineral deposits from 30 surgically excised natural aortic valves were examined. The control group consisted of autopsy samples (aortic valves, vertebral bodies) and teeth obtained after extraction. Micro-computed tomography (micro-CT) was used to describe the morphology and density of the minerals. X-ray fluorescence and Fourier transform infrared spectroscopy were applied to determine the chemical composition. RESULTS A poorly crystalline, B-type carbonate-containing hydroxyapatite (HAP) was found to constitute the mineral phase of the aortic valve leaflets. No other chemical compounds were identified. The elemental composition of the minerals in aortic valves and bone/tooth did not differ markedly, except that the Mg concentration was fourfold higher in valve material. The aortic valve deposits were irregular in shape and occupied ca. 40% of the leaflet volume. The volume of the deposits were spread over a broad range (0.001-0.3 mm3), while the density ranged from that of dentine to enamel (average value 2.2 g/cm3), slightly higher than that of compact bone. CONCLUSION The aortic valve deposits were identified as B-type carbonate-containing HAP, and were not identical to those found in bones and teeth, the main difference being a fourfold elevated Mg content. Mg may have been deposited as a separate compound, as micro-CT results suggested that the formation of mineral deposits in aortic valves was a multi-factorial process. The morphological parameters and densities of the valve deposits were spread over a broad range (factor approximately 300). An unequivocal identification of the mechanism responsible for the aortic valve pathological calcification was not possible, however.

Abstract
INTRODUCTION The anterior communicating artery (ACoA) is the most frequent site of intracranial aneurysm location. Despite many studies the frequency of aneurysm occurrence with anatomical anomalies is still poorly described. Moreover the significance of the A2 segment of anterior cerebral artery anomalies has been neglected. The aim of this study was to determine the frequency and types of variations of the anterior cerebral circulation in patients with ACoA aneurysms and to analyze their relation to aneurysm occurrence in the Polish population. MATERIALS AND METHODS We studied 50 patients with an established radiological diagnosis of ACoA aneurysm and 100 healthy age- and sex-matched controls using Computed Tomgraphy Angio- graphy. Maximum Intensity and Volume Rendering Projections were used to examine the cerebral arterial circulation. Univariate logistic regression was used to determine the statistical association between ACoA complex anomalies and aneurysm occurrence. RESULTS Patients in the study group had a significantly higher incidence of hypoplastic A1 seg- ment of the anterior cerebral artery (24% vs. 7%; p <0.01) and aplastic A1 segment of the anterior cerebral artery (12% vs. 3%; p = 0.03). The frequency of A1 segment hypoplasia or aplasia in the study group was 36%. There was a statistical trend regarding A2 segment aplasia/hypoplasia as a potential predictor of ACoA aneurysm (6% vs. 1%; p = 0.07). CONCLUSION Occurrence of an ACoA aneurysm is associated with hypoplasia or aplasia of the A1 segment of the anterior cerebral artery. A2 segment anomalies may potentially be associated with aneurysm formation.

The whole vascular bed of 16 uteri was injected with synthetic resin Mercox CL-2R and then the uteri were corroded in potassium hydroxide. Next 16 uteri were injected with acrylic emulsion, Liquitex R. Their vascular bed was studied using immunohistochemistry for von Willebrandt's factor. Immunohistochemistry allowed to visualize the vessels within the intratumoral septa, while SEM allowed to differentiate the vessels, which were mainly the venules and the veins. Apart from the veins the intratumoral septa were consisted of small arteries and capillaries.

Abstract
This report presents the craniofacial morphology of a skull afflicted with hydrocephalus, belonging to an adult male who lived in the 19th century in Vienna. The volume of the skull (2022 cm3) exceeds normal capacity of a male skull which is estimated to be 1500 cm3. Diameters of the neurocranium and head circumference of the specimen differ significantly from normative values, while the facial diameters remain in normal range of variation. Characteristic features of the investigated skull are numerous accessory bones and sutures of the neurocranium. Overall the morphology of the cranial bones suggests that the male suffered from congenital hydrocephalus.

Abstract
AIM he main goal of this study was assessment of vascular structure of cervical uterine leiomyomata. MATERIALS AND METHODS The study was carried out on ten human uteri collected upon autopsy. Vessels were injected with synthetic resin, next corroded and coated with gold, finally observed using scanning electron microscope. RESULTS Most of cervical fibroids were observed in the middle third of the wall of cervix. They were surrounded by relatively dense 'vascular capsule'. consisted of flattened vein, arterioles and capillaries. CONCLUSIONS Structure of cervical uterine leiomyomata was similar to those observed in initial stage of growth of myometrial fibroids.

Abstract
BACKGROUND The aim of this study was to determine the prevalence of the different types of median nerve thenar motor branch and to compare them with literature data. MATERIAL AND METHODS This study was conducted using median nerves dissected from cadavers stored in a 10% solution of formaldehyde at the Department of Anatomy of Jagiellonian University Medical College (JUMC) and cadavers from the Department of Forensic Medicine JUMC. The research protocol was approved by the Jagiellonian University Ethics Committee (registry KBET/ /209/B/2002). RESULTS The studied group comprised 8 (26.7%) women and 22 men (age between 23 and 92 years), yielding a total of 60 thenar motor branches (30 right vs. 30 left). Forty-seven (78.3%) nerves were classified as extraligamentous, 12 (20%) were subligamentous, and 1 (1.7%) was transligamentous. As for the side of origin of the thenar motor branch, in 45 (75%) cases it was the radial side and in 2 (3.33%) cases it was the ulnar side. CONCLUSIONS The obtained results confirm that the extraligamentous type of thenar motor branch is the most common and that the ulnar origin of the thenar motor branch is the rarest.

Abstract
BACKGROUND AND AIM The aim of this study was to assess the histological structure of the median nerve and its motor branch (number and arrangement of nerve bundles) and the cross-sectional area (CSA) of the median nerve (on the level of the carpal tunnel). MATERIAL AND METHODS This study has been conducted using median nerves dissected from cadavers stored in a 10% solution of formaldehyde at the Department of Anatomy of the Jagiellonian University Medical College and cadavers from the Department of Forensic Medicine of the Jagiellonian University Medical College. After dissection the median nerves were stained with haematoxylin and eosin and histological slides were prepared. These were later photographed (16 x magnification) and analysed using ImageJ software. The research protocol was approved by the Jagiellonian University Ethics Committee (registry KBET/209/B/2002). RESULTS The studied group comprised 8 women and 22 men (age between 23-92 years), yielding a total of 60 median nerves (30 right vs. 30 left). In 4 (6.67%) cases an accessory motor branch was found. The mean CSA of the median nerve was 0.19 cm(2). The median nerves from the right hand had a statistically larger CSA (p = 0.017). The number of nerve bundles in the median nerve varied between 13 to 38 and in the motor branch of the median nerve between 4 to 14. CONCLUSIONS The nerve bundles of the median nerve, at the level of the carpal tunnel, display no particular type of arrangement. ImageJ software proved useful in the assessment of the histological structure of the human median nerve and its motor branch.
