Introduction

Eagle syndrome is a rare disease that causes elongation (>30 mm) of the temporal styloid process (SP) through osteogenesis (Type I) or ossification of the stylohyoid ligament (SHL) (Type II). Eagle syndrome implicates the styloid apparatus and can cause difficulty with swallowing, pain with neck movement, dissection of the internal carotid artery, and stroke. Reports investigating the Eagle syndrome gross anatomy and SP microstructure are scarce. This study seeks to investigate a case of Eagle syndrome SPs in a human cadaver with gross and micro-CT analysis and discuss its clinical significance.

Methods

The case was discovered during routine academic dissection of an adult male human cadaver. The styloid apparatus was examined bilaterally for any non-typical morphologies. The SPs were stripped of extraneous tissue and photographed. Linear and angular dimensions of the SPs were measured, and micro-CT analysis was performed on a section of the right SP. A comprehensive review of Eagle syndrome etiology, epidemiology, symptomology, diagnostic parameters, subtype descriptions, and treatment was compiled from current literature as a basis for clinical discussion.

Results

The long axes of the right and left SPs measured 41.4 mm and 33.0 mm, respectively, and the proximal, middle, and distal SP diameters averaged 4.2 mm, 3.5 mm, and 1.7 mm, respectively. Both SPs exhibited a mid-shaft tubercle, after which they decreased diameter by over 25% within 2 mm distance, increased angle of descent by more than 20.0° in the sagittal plane and exhibited noticeably different surface characteristics. Micro-CT analysis revealed relatively consistent trabeculae and cortical structure throughout the SP.

Conclusions

Clinical understanding of SP hyperplasia vs. SHL metaplasia as it applies to Eagle syndrome etiology and subsequent implications to the styloid apparatus is important for Eagle syndrome diagnosis, treatment, and patient outcomes. As Eagle syndrome can present with broad symptomology, this report may benefit primary care physicians, dentists, neurologists, radiologists, otorhinolaryngologists, and other medical professionals with information that can be used to improve diagnostic testing and treatment approaches in patients with Eagle syndrome.
eagle综合征是一种罕见的疾病,通过成骨(I型)或茎突舌骨韧带(SHL)骨化(II型)导致颞骨茎突(SP)伸长(30mm)。Eagle综合征累及茎突,可引起吞咽困难、颈部运动疼痛、颈内动脉夹层和中风。关于Eagle综合征大体解剖和SP显微结构的报道很少。本研究通过大体和显微ct分析对1例人尸体的鹰综合征SPs进行研究,并探讨其临床意义。方法本病例是在对一具成年男性尸体进行常规学术解剖时发现的。双侧检查茎突器官有无非典型形态。SPs被剥去外部组织并拍照。测量SP的线性和角度尺寸,并对右侧SP切片进行显微ct分析。根据现有文献,对Eagle综合征的病因学、流行病学、症状学、诊断参数、亚型描述和治疗进行综合综述,作为临床讨论的基础。结果右、左SP长轴直径分别为41.4 mm和33.0 mm,近端、中端和远端SP长轴直径分别为4.2 mm、3.5 mm和1.7 mm。两种SPs均表现为中轴结节,此后在2 mm距离内直径减小25%以上,矢状面下降角增加20.0°以上,表面特征明显不同。显微ct分析显示整个SP的小梁和皮质结构相对一致。结论SP增生与SHL化生的临床认识,因为它适用于Eagle综合征的病因和随后对茎突器官的影响,对Eagle综合征的诊断、治疗和患者预后都很重要。由于Eagle综合征可以表现出广泛的症状,本报告可以为初级保健医生、牙医、神经科医生、放射科医生、耳鼻喉科医生和其他医疗专业人员提供信息,用于改进Eagle综合征患者的诊断测试和治疗方法。

Background

Musculoskeletal (MSK) anatomy is fundamental to clinical practice in various healthcare disciplines, including medicine, physiotherapy, and orthopedics. Advancements in technology have led to an increased focus on online learning tools, providing alternatives to traditional teaching methods.

Objective

This systematic review assesses the impact of online learning (e-learning) modules on musculoskeletal anatomy education among health professionals.

Methods

A comprehensive search was conducted across Scopus, PubMed, Cochrane, Web of Science, and CINAHL. The eligibility criteria included studies involving health professionals and students in anatomy education using online learning interventions such as video lectures, 3D models, and virtual labs. The risk of bias of the studies was evaluated via the JBI Checklist.

Results

Out of 947 records, 18 studies were included in this review. This review included 8 quasi experimental, 7 cross-sectional, 1 case‒control, and 2 randomized controlled trials (RCTs). A total of 78 % of the studies incorporated multiple online interventions, such as video tutorials, interactive 3D models, and virtual laboratories. Additionally, 67 % of the studies indicated that learners preferred hybrid models that combined online and in-person teaching, as they significantly enhanced the learning experience compared with traditional methods in improving anatomical knowledge and musculoskeletal competency. Modules that incorporated practical elements significantly increased learners’ confidence in handling musculoskeletal cases. The pandemic accelerated the adoption of online anatomy education, with many studies demonstrating that digital platforms successfully replaced traditional methods while achieving comparable educational outcomes.

Conclusions

Online educational modules offer a beneficial alternative to traditional anatomy teaching methods, particularly when interactive and hybrid models are in use. They enhance MSK knowledge retention, clinical skills, and learner satisfaction. Future studies should aim to optimize these technologies to integrate theoretical knowledge with clinical practices and patient education.

Introduction

According to standard anatomical description, the radial artery typically originates as one of two terminal branches of the brachial artery within the cubital fossa. Despite the common embryological process of the upper limb arteries, there are anatomical variations in the origin of the radial artery such as the radial artery originating from the axillary artery or from the brachial artery in the arm. The present study aimed to investigate the origin of the radial artery within a select adult cadaveric South African sample.

Methods

A total of thirty adult cadaveric specimens (n = 60 upper limbs) were dissected at the University of KwaZulu-Natal (BREC/00006978/2024).

Results

The radial artery originated from the brachial artery in the cubital fossa as per standard anatomical description in 90 % of the upper limb specimens. In 10 % of the sample, the aberrant radial artery originated from the axillary artery (four unilaterally, and one bilaterally in an 80-year-old male cadaver). The aberrant radial arteries originated an average 172 ± 20.81 mm above the inter-epicondylar line of the humerus, with external and internal diameters of 5.45 ± 1.71 mm, and 3.10 ± 0.70 mm respectively.

Conclusion

This study reports an incidence of 10 % of the sample in which the radial artery originated from the axillary artery. Knowledge of the variations in the origin of the radial artery within this select South African population may assist the clinician during coronary and neuro-interventional procedures.
根据标准的解剖学描述,桡动脉通常起源于肘窝内的肱动脉的两个末端分支之一。尽管上肢动脉具有共同的胚胎学过程,但桡动脉的起源在解剖学上存在差异,如桡动脉起源于腋窝动脉或臂动脉。本研究旨在调查桡动脉的起源在一个选择的南非成人尸体样本。方法在南非夸祖鲁-纳塔尔省大学(BREC/00006978/2024)对30例成人尸体标本(n = 60例上肢)进行解剖。结果90%的上肢标本桡动脉起源于肘窝的肱动脉,符合标准解剖描述。在10%的样本中,异常的桡动脉起源于腋窝动脉(4例单侧,1例双侧,一例80岁男性尸体)。异常桡动脉平均发源于肱骨上髁间线上方172±20.81 mm,外径5.45±1.71 mm,内径3.10±0.70 mm。结论本研究报告了10%的病例中桡动脉起源于腋窝动脉。了解这些选定的南非人群中桡动脉起源的变化可能有助于临床医生进行冠状动脉和神经介入手术。

Introduction

An empty sella anatomical finding is characterized by the pituitary gland (hypophysis) being flattened against the wall of the sella turcica (hypophyseal fossa). Many neurologic and endocrinologic symptoms can ensue from pituitary gland deformity, resulting in empty sella syndrome (ESS) which is often diagnosed via computed tomography that showing the apparent “empty sella.” Gross cadaveric imaging and histological analysis of empty sella findings are scarcely reported in the literature but may help understand the condition. The objective of this study is to investigate a cadaveric case of complete primary empty sella (PES) with gross imaging, histological analysis, and a comprehensive clinical review.

Methods

An empty sella finding was discovered during routine dissection of the basicranium in an elderly male human cadaver obtained from an ethically approved body donor program. The case was photographed in situ from multiple viewpoints. The head was sectioned in the midsagittal plane and photographed with scale to show the morphology of the remnant pituitary gland. Consistent dissections, photographs, and measurements were performed on another cadaver with typical pituitary anatomy for side-by-side comparison. Histological analysis was performed on the compressed pituitary gland and examined via light microscopy.

Results

Gross examination of this empty sella case revealed a characteristic complete PES due to herniation of cerebrospinal fluid (CSF) through a collapsed diaphragma sellae. Despite the significant compression and reduction of pituitary gland volume, its tissue organization and cell characteristics remained proportionally consistent with typical pituitary tissue. The cadaver's age (90+ years) and sex (male) made for unique and valuable clinical discussion.

Conclusions

The present case offers a thorough analysis of an empty sella case, uniquely including gross anatomy photos, histological examination, and a thorough review of clinical implications regarding the rarity of a complete PES in an advanced-aged male individual. This report serves to provide important clinical insights to anatomists, neurologists, endocrinologists, and medical educators about empty sella clinical implications.
空鞍解剖表现为垂体(垂体窝)紧贴鞍壁被压平。垂体畸形可引起许多神经系统和内分泌系统症状,导致空蝶鞍综合征(ESS),通常通过计算机断层扫描诊断,显示明显的“空蝶鞍”。大体的尸体成像和空鞍的组织学分析在文献中很少报道,但可能有助于了解这种情况。本研究的目的是通过大体影像、组织学分析和全面的临床回顾来研究一例完全性原发性空鞍(PES)的尸体病例。方法在对一具经伦理批准的捐献者老年男性尸体进行常规解剖时发现空鞍。该案件是从多个视点拍摄的。在中矢状面对头部进行切片,并用比例照相显示残余垂体的形态。在另一具具有典型垂体解剖结构的尸体上进行了一致的解剖,照片和测量,以进行并排比较。对压缩后的垂体进行组织学分析,并进行光镜检查。结果该空蝶鞍病例的大体检查显示特征性完全性PES,是由经蝶鞍膈塌陷的脑脊液(CSF)疝引起。尽管垂体体积明显压缩和缩小,但其组织组织和细胞特征仍与典型垂体组织保持比例一致。尸体的年龄(90岁以上)和性别(男性)是独特而有价值的临床讨论。结论:本病例对一例空蝶鞍病例进行了全面的分析,包括大体解剖照片、组织学检查,并全面回顾了一例老年男性个体完全性PES罕见的临床意义。本报告为解剖学家、神经学家、内分泌学家和医学教育者提供了关于空鞍临床意义的重要临床见解。

Background

Enteric nervous system comprises enteric neurons and glia, derived from neural crest cells, and regulates the gastrointestinal function. Previous animal studies have highlighted the essential roles of RET and SOX10 genes, along with PGP9.5 and S100b proteins, in the development of neurons and glia. This study investigates the expression of these genes and proteins in the human fetal gut wall.

Methods

Tissue samples of the human fetal gut wall were stained using haematoxylin and eosin, phosphotungstic acid haematoxylin, Beilschowsky silver, and Masson's trichrome to examine the histomorphology of neurons and glia. Immunohistochemistry and qPCR were used to analyse the expression of PGP9.5, S100b proteins, RET and SOX10 genes.

Results

Human fetal stomach and small intestine showed diverse neuronal and ganglionic morphologies. Neuronal migration occurred from the serosa through the muscle layers to the submucosa throughout all trimesters. As fetal age advanced, the number of neurons and glia decreased in the serosa and increased in the muscle layers and submucosa. PGP9.5 showed strong expression in the serosa and moderate expression in the deeper layers of the colon during the first trimester. Its expression diminished in the serosa and intensified in the inner layers with advancing gestation. S100b followed a similar pattern but was absent in epithelium. Expression of RET and SOX10 genes increased during the second and third trimesters.

Conclusion

The expression patterns of RET and SOX10 genes, and PGP9.5 and S100b proteins support their roles in the development of enteric neurons and glia in the human fetal gut wall.
肠神经系统由肠神经元和神经胶质组成,它们来源于神经嵴细胞,并调节胃肠功能。先前的动物研究已经强调了RET和SOX10基因以及PGP9.5和S100b蛋白在神经元和胶质细胞发育中的重要作用。本研究探讨了这些基因和蛋白在人胎儿肠壁中的表达。方法采用苏木精和伊红、磷钨酸苏木精、Beilschowsky银和Masson三色染色法对人胎儿肠壁组织样本进行染色,观察神经元和神经胶质的组织形态学变化。采用免疫组织化学和qPCR分析PGP9.5、S100b蛋白、RET和SOX10基因的表达。结果人胎儿胃和小肠的神经元和神经节形态多样。在整个妊娠期,神经元从浆膜通过肌肉层迁移到粘膜下层。随着胎龄的增加,浆膜中的神经元和胶质细胞数量减少,而肌肉层和粘膜下层的神经元和胶质细胞数量增加。在妊娠早期,PGP9.5在浆膜中表达强烈,在结肠深层中表达适度。随着妊娠的推进,其在浆膜的表达减少,在内层的表达增强。S100b具有类似的模式,但在上皮中不存在。RET和SOX10基因的表达在妊娠中期和晚期增加。结论RET和SOX10基因以及PGP9.5和S100b蛋白的表达模式支持它们在人胎儿肠壁肠神经元和胶质细胞发育中的作用。

Background

Sciatic nerve injury, characterised by radiating pain from the lumbosacral region and associated motor-sensory deficits, remains a challenging condition with limited regenerative therapies. Clitoria ternatea (CT), a medicinal plant known for its neuroprotective and anti-inflammatory properties, has shown promise in promoting nerve regeneration. This study aimed to evaluate the therapeutic efficacy and safety of CT extract in a rat model of sciatic nerve crush injury.

Methodology

A total of 54 Sprague-Dawley rats were divided into six groups: normal, toxicity control, negative control (injury without treatment), positive control (methylcobalamin), and three CT treatment groups (250, 500, and 1000 mg/kg/day for 28 days).

Results

Hepatic and renal histology confirmed no toxicity in CT-treated groups. Functional recovery was assessed on days 14 and 28 using walking track analysis, rotarod, toe-spreading reflex, and hot plate tests, all showing significant improvement in CT-treated and positive control groups. Muscle histology (gastrocnemius, soleus, and extensor digitorum longus) and weight analysis revealed reduced atrophy and enhanced regeneration, particularly in the high-dose CT and positive groups. Morphometric evaluation using toluidine blue and cresyl violet staining indicated accelerated remyelination and increased neuronal cell body preservation. Transmission electron microscopy (TEM) further demonstrated increased myelin sheath thickness in treated groups.

Conclusion

These findings suggest that CT promotes axonal regrowth and functional recovery without detectable toxicity. This study provides novel preclinical evidence supporting the neuro regenerative and protective potential of Clitoria ternatea in peripheral nerve injuries, highlighting its promise as a plant-based therapeutic candidate for future translational applications.

Background

Infertility remains a significant challenge in reproductive medicine, affecting both men and women. Recent advances in animal-based simulations of implant surgery have provided translational platforms for developing innovative reproductive therapies.

Objectives

To review the role and progress of animal-based surgical implant models in enhancing gametogenesis, hormone production, and reproductive organ integrity, and to discuss their translational potential for treating infertility in men and women.

Methods

In this review, animal model studies simulating implant surgeries for reproductive organs were analyzed to assess their potential in treating infertility. The investigation included a comprehensive review of advancements in microsurgical techniques, biological implants, and robotic-assisted procedures that enhance the precision and effectiveness of implant placement. Ethical guidelines governing preclinical development were also considered to ensure the suitability and safety of these approaches for future human application. Additionally, histopathological and genetic evaluations were examined as critical tools for optimizing implant design and function.

Results

The results indicate that a broad spectrum of implants has been developed, ranging from autologous testicular and ovarian tissue grafts to artificial reproductive tissue scaffolds. In male infertility, testicular implants and prostheses designed for vasectomy reversal have demonstrated efficacy in restoring sperm production and addressing azoospermia. For female infertility, ovarian implants have been shown to support follicular growth, while fallopian tube and uterine prostheses facilitate embryo transfer and implantation. Technological advancements, including microsurgical and robotic assistance, have significantly improved the accuracy and success rates of these interventions. Preclinical studies have emphasized strict adherence to ethical standards and have utilized histopathological and genetic analyses to guide the refinement and optimization of these implants for clinical use.

Conclusions

Surgical implants, when combined with assisted reproductive technologies, offer promising avenues for restoring fertility. However, clinical translation faces challenges related to biological compatibility and long-term function. Future research will focus on bioengineered constructs that integrate stem cells and smart biomaterials to further enhance therapeutic outcomes.

Introduction

Anatomical variations of the iliopsoas complex can have clinical relevance, particularly those involving the femoral nerve. This report describes a previously undocumented psoas muscle variant and two additional muscular anomalies which may have implications for nerve entrapment and hip dysfunction, though further research is required to establish clinical significance.

Methods

Routine dissection of the posterior abdominal wall was performed in 2024 on an adult female cadaver as part of an anatomy course at Liberty University. The dissection was carried out by a graduate teaching assistant (medical student) under the supervision of faculty anatomists. Detailed anatomical observations were recorded and compared to existing literature on iliopsoas variants.

Results

A bilateral muscle was identified originating from the medial aspect of the iliolumbar ligament and inserting into the posterior fibers of psoas major. It received distinct innervation from the femoral nerve. A review of literature revealed no prior documentation of this variant. Two additional variants were observed: prominent medial loops of the iliacus muscle and bilateral psoas quartus muscles dividing the femoral nerve.

Conclusion

These variants may contribute to femoral nerve compression or snapping hip syndrome, especially in patients with idiopathic or recurrent symptoms. Recognition of such anatomical variations can aid in diagnosing unexplained groin pain or failed regional anesthesia and supports the need for more comprehensive documentation of iliopsoas morphology.
髂腰肌复合体的解剖变异具有临床意义,特别是涉及股神经的变异。本报告描述了一种以前未记载的腰肌变异和另外两种可能与神经卡压和髋关节功能障碍有关的肌肉异常,尽管需要进一步的研究来确定其临床意义。方法于2024年在利伯缇大学解剖学课程中对一具成年女性尸体进行常规后腹壁解剖。解剖是由一名研究生助教(医科学生)在教员解剖学家的监督下进行的。详细的解剖观察记录下来,并与现有的髂腰肌变异文献进行比较。结果发现双侧肌起源于髂腰韧带内侧,伸入腰大肌后纤维。它受到股神经的明显支配。文献回顾显示没有此变体的先前文档。观察到另外两种变异:髂肌和双侧腰阔肌的突出内侧袢分隔股神经。结论这些变异可能导致股神经受压或咔髋综合征,特别是在有特发性或复发症状的患者中。识别这种解剖变异有助于诊断不明原因的腹股沟疼痛或区域麻醉失败,并支持对髂腰肌形态进行更全面记录的需求。

Background

Alveolar regeneration is essential for maintaining lung function and enabling recovery following lung injury. Impairment of this process contributes to the progression of various respiratory diseases. A detailed understanding of the cellular and molecular mechanisms driving alveolar repair is crucial for the development of effective therapeutic strategies.

Methods

A literature search was conducted in PubMed, Scopus, and Google Scholar focusing on the history of alveolar regeneration and the cells involved in this process, the effects of aging, and associated therapeutic implications. The keywords used in the search included “alveolar regeneration,” “aging,” “cell senescence,” “stem cells,” “growth factors,” and “therapeutic potential.”

Results

This review explores the key cellular players involved in alveolar repair, focusing particularly on alveolar type 2 cells and other progenitor populations that contribute to alveolar epithelial renewal. This review also highlights how aging affects regenerative capacity, as age-related cellular dysfunction may impair lung repair and exacerbate chronic pulmonary conditions. Furthermore, novel insights into alveolar regeneration are reviewed, including recent advancements in in vivo and in vitro models as well as single-cell technologies that provide a deeper understanding of the regenerative process. Emerging therapeutic strategies, such as stem cell–based therapies, gene editing, and pharmacological interventions, are also discussed in the context of enhancing alveolar regeneration.

Conclusions

By integrating recent discoveries and identifying key knowledge gaps, this review provides a comprehensive overview of alveolar regeneration and emphasizes potential therapeutic approaches for promoting lung repair and restoring respiratory function.

Reliability of using CBCT scans to derive the parameters of the facial canal 使用CBCT扫描得出面部管参数的可靠性
Q3 Medicine Pub Date : 2025-06-10 DOI: 10.1016/j.tria.2025.100409

Purpose

Studies have analysed the facial canal (FC) parameters using dissection or imaging technologies. To date, no studies have analysed the differences between these methods. The purpose of this study was to evaluate the reliability and accuracy of deriving the parameters from the FC on cone-beam computed tomography (CBCT) scans by comparing it to FC morphometric analyses of dissected heads.

Methods

Ten embalmed heads (n = 20) were CBCT scanned and analysed using ImageJ. Next, each FC segment was dissected. Measurements for both methods included the proximal and distal diameters and lengths for each segment, and angles of the first and second genua.

Results

The paired t-test indicated significant differences (p < 0.05) between the CBCT and dissected measurements for most FC segments measured. The respective dissection measurements were consistently higher than the CBCT measurements. However, the Bland-Altman plots showed agreement between the two modalities in measuring FC segments. Interobserver error values were 0.963 and 0.950 for the CBCT and dissection groups, respectively, indicating a high repeatability.

Conclusion

Although the current study showed differences between the parameters of the FC derived from CBCT scans and dissected measurements, CBCT scans remain a valuable tool for non-invasive assessments. However, the differences have implications for modelling in that CBCT measurements underestimate the true size for the various segments of the FC. It is worth noting that a potential difference in segment sizes may exist between populations but will have no effect on using CBCT scans as a pre-operative assessment of the FC.
目的研究采用解剖或成像技术对面管(FC)参数进行分析。迄今为止,还没有研究分析过这些方法之间的差异。本研究的目的是评估锥束计算机断层扫描(CBCT)中FC参数的可靠性和准确性,并将其与解剖头部的FC形态计量学分析进行比较。方法对20例经防腐处理的头颅进行CBCT扫描,并用ImageJ进行分析。接下来,切开每个FC节段。两种方法的测量包括每个节段的近端和远端直径和长度,以及第一和第二膝的角度。结果配对t检验显示差异有统计学意义(p <;对于大多数FC节段的测量,CBCT和解剖测量之间的差异为0.05)。各自的解剖测量值始终高于CBCT测量值。然而,Bland-Altman图显示在测量FC段时两种方式是一致的。CBCT组和夹层组的观察者间误差值分别为0.963和0.950,重复性高。尽管目前的研究显示CBCT扫描和解剖测量得出的FC参数存在差异,但CBCT扫描仍然是一种有价值的非侵入性评估工具。然而,这些差异对建模有影响,因为CBCT测量低估了FC各个部分的真实大小。值得注意的是,人群之间可能存在潜在的节段大小差异,但对使用CBCT扫描作为FC术前评估没有影响。
