Background: Schwannoma and neurofibroma constitute benign peripheral nerve sheath tumors (BPNSTs), which may present as single or multiple lesions. Multiple schwannomas are rare in the peripheral nerves of the upper extremity. Solitary small schwannoma is usually asymptomatic, while larger and multiple schwannomas may have different symptoms due to pressure effects. Median and ulnar nerve communications are often encountered in the upper limb, making these anastomoses clinically important. However, such communications with schwannomas in the axilla are rare. Case Report: The study protocol was designed per the prevailing guidelines of the Institute on the use of human cadavers for teaching and research. Written informed consent was obtained from the family of the body donor at the time of whole-body donation. The upper extremities, including the brachial plexuses of both sides, were carefully dissected as per the instructions in Cunningham’s Manual of Practical Anatomy15th edition. Discussion: Unusual anastomoses in the axilla and two encapsulated, highly vascular fusiform masses were observed. Another fairly large mass was noted on the right chest wall. Histological examination confirmed the masses to be schwannomas. Conclusion: Asymptomatic schwannomas often remain undiagnosed, and those lying in the axilla can be misdiagnosed. Awareness of such variant anatomy will enable clinicians and surgeons to plan more appropriate diagnostic and therapeutic interventions. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study aimed to assess the perceived need among surgical residents to revisit their anatomical knowledge and evaluate their attitude towards integrating clinical anatomists into surgical residency program curriculum. BACKGROUND: While medical students learn human anatomy during undergraduate years, the practical application of clinically oriented anatomy becomes vital in surgical specialties. However, this aspect has not been adequately addressed in Indian surgical residency programs. METHODS: An 11-item questionnaire, including closed-ended and Likert-scale questions, was administered to 153 surgical residents. Consent was obtained, and responses were collected via Google Forms. RESULTS: Half of the respondents (50%) felt confident in their self-d irected anatomy learning, but 87% believed integrating clinical anatomists would enhance their su rgical expertise. Additionally, 88% saw value in revisiting cadaveric dissection. Third-year residents showed a significantly higher inclination towards cadaveric dissection. Deficiencies in the curriculum and time constraints were identified as major barriers. CONCLUSION: The study highlights a perceived need among surgical residents to augment their anatomical knowledge, advocating for the integration of clinical anatomists and cadaveric dissection into training. A collaborative approach, emphasizing both horizontal and vertical integration of anatomy, is recommended to enhance surgical education and practice. (Tab. 4, Fig. 1, Ref. 25).

The median sacral artery (MSA) is the single unpaired dorsal branch of the abdominal aorta. The present case describes the relatively unusual origin of the median sacral artery in common with the fourth pair of lumbar arteries via a common trunk in a 74-year-old male cadaver. Unusual common trunk is prone for iatrogenic injury in surgeries of the lumbar and pelvic region. Owing to the deep seated nature of MSA close to the periosteum of lumbar vertebrae and sacrum, detection of accidental rupture of MSA and ligation thereof becomes a difficult task. MSA is also increasingly being utilized for intra-arterial embolization of pelvic tumours. The proximal portion of the common origin may at times undergo cone shaped dilatation which is referred to as infundibulum or infundibular dilatation and can also transform into aneurysm later. Knowledge of this variation is imperative for spine and pelvic surgeons to avoid unwanted complications. [ABSTRACT FROM AUTHOR]

This document is a letter to the editor of the Medeniyet Medical Journal, titled "Clarifications Regarding 'Investigation of Morphological and Biomechanical Properties of the Scapula for Shoulder Joint'." The authors of the letter express their interest in the article and commend the authors for their efforts. However, they raise several points of clarification and concern, including negative values in calculations, missing references, and incomplete information about the sample size and scapulae used. They also request clarification on the use of the term "biomechanics" in relation to a study conducted on dry bone. The authors conclude by expressing their appreciation for the editor's consideration and requesting a response from the original authors. [Extracted from the article]

Anterior external arcuate fibers (AEAF) are efferents of the arcuate nuclei, which are located on the ventral surface of pyramids. Several types of fibre bundles superficial to the pyramids have been described in early and mid 20th century. Recently, few of these have been studied in detail. Objective of present study was to observe the morphology of AEAF in the Indian population. Distinct AEAF were noted in 13 out of 50 brain specimens. Based on their relation to olive, AEAF were further classified as supraolivary, preolivary and supraolivary fibers and their prevalence noted as 25%, 15%, and 9% respectively. Supraolivary and preolivary fibers were present together in 9 brainstem sides, while co-presence of preolivary and circumolivary fibers was noted in only 1 side. All three types of fibres were observed together in 5 brainstem sides. When present bilaterally, supraolivary and preolivary fibers were seen in 92.30% and 66.66% of brainstem respectively, while circumolivary fibers were seen bilaterally in 28.57% of brainstem. Supraolivary and circumolivary fibers exhibited variable morphology as single, double and multiple fiber bundles. Morphometric analysis revealed presence of thicker supraolivary fiber bundle on right side, while thicker circumolivary fiber bundles were noted on left side. Present study will add to knowledge of this variable fiber bundle pattern, which has been reported to play an important role in regulation of crucial physiological functions such as breathing and cardiorespiratory mechanisms. These observations open avenues for further research into developmental factors involved in migration of neurons from the rhombic lip.
