Knowledge about the morphology of BMC may help to understand the development course of condyle and differential diagnosis of fractures or tumors in condylar area. The aim of this study was to examine temporomandibular joint (TMJ) hard tissue morphology of BMCs.Materials and methods: 1900 cone beam computed tomography (CBCT) scans of the mandibular condylar heads examined for the presence of bifidity. When BMC were identified, morphological assessment and measurements of bone components of TMJ were done.Results: 69 BMC were detected in 56 patients (3%). It was observed that 43 (76.8%) patients presented unilateral and 13 (23.2%) patients presented bilateral BMCs. 59.4% of condyles were mostly seen in mediolateral (ML) orientation and 40.6% of them were both ML and anteroposterior (AP) orientation. 46.4% of cases showed wide and shallow groove; 53.6% had deep and narrow groove on coronal images. 60 BMCs had osteoarthritic changes.Conclusions: CBCT is an excellent imaging modality for accurate imaging of the bony components of TMJ. Due to the widespread use of CBCT, the prevalence of BMC is likely to be higher than has been previously reported and reported new cases in literature could be useful for dentists for improving their knowledge about this variation.","PeriodicalId":12251,"journal":{"name":"Folia morphologica","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their well-documented functions, the impact of preserving or reconstructing these ligaments during surgical procedures, particularly radical prostatectomy, on continence outcomes remains underexplored. This systematic review synthesizes current evidence on the anatomy, function, and clinical implications of the PPL and PVL. A comprehensive literature search was conducted in PubMed following PRISMA guidelines, selecting studies related to the anatomical characteristics, functional roles, and clinical management of these ligaments. Anatomical studies consistently highlight the structural complexity and supportive roles of the PPL and PVL in maintaining urethral and bladder neck positioning, which are essential for continence. Functional studies on the other hand further explain their involvement in the urethral closure process while clinical evidence demonstrates that sparing or reconstructing these ligaments during radical prostatectomy significantly improves both early and long-term continence outcomes, suggesting that their preservation is crucial for enhancing postoperative continence recovery. The findings emphasize the importance of these ligaments in continence mechanisms and advocate for their consideration in future surgical innovations. Further research is needed to refine surgical techniques and to better understand the biomechanical properties of these ligaments to optimize patient outcomes.","PeriodicalId":12251,"journal":{"name":"Folia morphologica","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its borders, during robotic, laparoscopic or open radical prostatectomy for intermediate or high-grade prostate cancer, have long been defined and must be usually respected; the genitofemoral nerve represents the extended pelvic lymph-node dissection lateral boundary and may vary from case to case putting its integrity at risk.Materials and methods: For the first time, here the authors report genitofemoral nerve branching pattern data obtained extended pelvic lymph node dissection during videolaparoscopic radical prostatectomyand propose a further sub-classification to identify the exact genitofemoral nerve bifurcation point in correlation with the injury risk.Results: The surgical results show the prevalence of a genitofemoral nerve originating as a single trunk which divides into two branches and highlight how this condition occurs at external iliac artery upper third in more than 75% of cases. Furthermore, at the femoral canal inlet the genitofemoral nerve two branches were mainly seen lying laterally sided and below the external iliac artery, or in the middle of external iliac artery and external iliac vein.Conclusions: Knowledge and recognition of the genitofemoral nerve course and bifurcation points deduced from the extended pelvic lymph node dissection and, in any case, applicable to all major pelvic surgery, can prove helpful in avoiding iatrogenic nerve injuries during extended pelvic lymph node dissection.","PeriodicalId":12251,"journal":{"name":"Folia morphologica","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library were searched through. The overall search process was conducted in 3 stages.Results: Overall, the analyses were based on the results of 3482 patients. The pooled mean surface area of the mastoid air cell system in adults was found to be 174.68 cm² (SE = 29.58). In children (14-18 years old) mean of the said parameter was found to be 114.36 cm² (SE = 44.21). The pooled mean volume of mastoid pneumatization in adults was found to be 7.74 cm³ (SE = 1.14). The pooled mean volume of the temporal bone pneumatization in adults was found to be 8.41 cm³ (SE = 0.58).Conclusions: The present meta-analysis analyzed the characteristics of TBP. Our results show the mean values of the morphometric properties of the air cell system in humans. This information may be highly significant when performing numerous otolaryngological procedures, such as mastoidectomies or skull base operations in the area of the petrous apex. Furthermore, the present study results prove how the size of the air cells increases with age.

Recent reports have suggested its potential involvement in mid-portion Achilles tendon tendinopathy. Therefore, this study aims to evaluate the morphological variations of the PM, focusing on its branching patterns at the level of insertion.Materials and methods: Dissections were performed on 58 lower limbs obtained from 29 adult cadavers preserved in a 10% formalin solution. The morphology of the PM was assessed concerning its branching patterns at the insertion level and its relationship with the calcaneal tendon.Results: The PM was present in 52 out of 58 cases (89.65%). In majority of these cases (37 limbs, 63.79%), there was no splitting of the plantaris tendon (PT) at the level of the extensor expansion (ExP). Bifurcation occurred in 10 cases (19.23%), trifurcation in 4 cases (7.69%), and in one instance, the tendon divided into four slips. In 11 cases (22.4%), the insertion blended with the Achilles tendon (Type VII), which may increase the risk of Achilles tendinopathy.Conclusions: The study indicates the existence of new types of PM tendon insertions that could potentially influence the development of Achilles tendinopathy. Variations in the anatomical morphology of the PM tendon may lead to potential conflicts with the Achilles tendon and the tibialis posterior tendon, thereby increasing the risk of tendinopathy.","PeriodicalId":12251,"journal":{"name":"Folia morphologica","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IMA artery was located between the origin of the brachiocephalic trunk and the left common carotid artery. The left vertebral artery was situated between the origin of the left common carotid artery and the left subclavian artery. No other variations in the origins of major vessels in the thoracic region, head, and neck were observed. The frequency of the left vertebral artery arising directly from the aortic arch is estimated to be 3-8%, and when combined with the IMA artery arising directly from the aortic arch, which occurs in less than 1% of cases, the variant described appears to be extremely rare.

Extracellular vesicles (EVs) are small secretory vesicles released from almost all mammalian cells. EVs-miRs cargo plays a significant role in regulating various aspects of the biological machinery of the recipient cells. EVs-miRs may play an essential role in promoting cellular regenerative functions. miRs contained within the EVs fractions are capable of preserving their function throughout their journey from the cell of origin to the host cells. The current review discusses the role of EVs-miRs in different renal diseases as a novel approach for managing particular renal injuries. We tried to simplify the possible modulatory impact of miRs at the ultrastructural cellular pathological signaling, demonstrating the hazardous and the beneficial subtypes based on the previous research work. Further investigations are still needed in this regard, as miRs may have dual effects, as EVs-miR-23a could attenuate renal fibrosis through activation of Akt and inhibition of FoxO1 signaling. Whereas, EVs-miR-23a was upregulated by the hypoxia-inducible factor (HIF-1a) in the hypoxic TECs and activated macrophages to accelerate the renal inflammatory cytokine storm and promote interstitial fibrosis.","PeriodicalId":12251,"journal":{"name":"Folia morphologica","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to evaluate knee morphology in Vietnamese women and assess the compatibility of available prostheses.Materials and methods: Using the full-leg CT scan datasets, we reconstructed 3D models of knee joints with software. After simulating femoral and tibial bone cuts with the mechanical alignment, the anteroposterior (AP) and mediolateral (ML) widths of the resection surfaces were measured. Six available prostheses were analyzed for their compatibility and coverage percent of the resected bone.Results: The study included 40 female patients with osteoarthritis (aged 51-79).

Smaller knees exhibited higher femoral aspect ratio (ML/AP) compared to larger knees. Increasing the tibial AP resulted in a smaller ML length of the proximal tibia relative to the tibial component. With the AP and ML mismatch set at ± 1.5 and ± 3 mm, prosthesis system provided the best femoral component fit at only 67.5%. Tibial component coverage rates varied among implant systems, with the best fit prosthesis system covering 92.5% at a tolerance of ± 3 mm for both AP and ML dimensions.Conclusions: The current prosthetic options show significant mismatches with the knee morphology of Vietnamese women, highlighting the need for better suited implant designs.
