Is it time for anatomists to enter the OT? Their role in clinical anatomy education of residents: A pre-trial survey research among surgeons.

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-directed anatomy learning, but 87% believed integrating clinical anatomists would enhance their surgical 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).

Accessory Flexor Carpi Ulnaris Muscle in Humans: A Rare Anatomical Case with Clinical Considerations.

Anatomical variations of the forearm flexor muscles are occasionally encountered. Though usually observed incidentally during autopsies or imaging studies, they may at times cause concern due to associated clinical symptoms. This report presents a case of unilateral accessory flexor carpi ulnaris (AFCU) muscle observed in a human male cadaver aged 78 years. During routine cadaveric dissection, an anomalous AFCU muscle was observed in the left forearm of a human male cadaver aged 78 years. Standard institutional guidelines pertaining to the use of human cadaver for teaching and research were followed. A thorough literature review about the flexor carpi ulnaris (FCU) through the PubMed, Embase and Google scholar databases was undertaken, using the keywords - accessory flexor carpi ulnaris muscle, aberrant flexor carpi ulnaris muscle and anatomical variation of flexor carpi ulnaris muscle. Relevant gross anatomical findings were recorded and photographed. AFCU was identified on the medial aspect of the distal third of the left forearm. The AFCU was found originating from the ante-brachial fascia and the fascia covering the FCU on the left forearm, forming a small separate belly deep to the main muscle. It terminated as a thin tendon running alongside the hypothenar muscles and attached distally to the base of the proximal phalanx of the little finger. The AFCU was found to be innervated by a branch of the ulnar nerve. Awareness about the rare AFCU muscle is clinically important as a possible cause of ulnar nerve compression but also as a possible graft in reconstruction surgeries.

A radio-anatomical study of median arcuate ligament syndrome: unveiling the morphology and morphometry of median arcuate ligament, celiac trunk, and superior mesenteric artery.

PURPOSE: In the context of medical literature, a significant lacuna exists in understanding median arcuate ligament syndrome (MALS). While clinical aspects are well documented, literature lacks a robust exploration of the anatomical relationship between the celiac trunk and the median arcuate ligament (MAL). METHODS: Morphometric parameters, including the vertebral level of MAL origin, MAL thickness, celiac trunk (CeT) origin level, diameter, and distances between CeT/Superior Mesenteric Artery (SMA) and the MAL center were observed on 250 CT angiograms. Cadavers (n = 11) were dissected to examine the same parameters and histo-morphological examination of MAL tissue was done. RESULTS: Radiological findings established average MAL thickness of 7.79 ± 2.58 mm. The celiac trunk typically originated at T12. The average distance between the celiac trunk and the MAL center was 1.32 ± 2.04 mm. The angle of the celiac trunk to the abdominal aorta was primarily obtuse. The average celiac trunk diameter was 5.53 ± 1.33 mm. Histological examinations revealed a diverse MAL composition, indicating variable mechanical properties. CONCLUSION: This study provides comprehensive morphometric data on the anatomical relationship between the MAL and the celiac trunk. In contrast to available literature which says the average MAL thickness of > 4 mm is an indicator of increased thickness, we observed much higher average thickness in the studied population. The findings contribute to a better understanding of normal anatomical variations which can serve as reference values for accurate radiological diagnosis of MALS. The histological examination revealed the heterogeneous nature of the MAL tissue composition, suggesting variable mechanical properties and functions in different regions.

The Attitude of Medical Students Toward Voluntary Body Donation: A Single Institute Survey and Narrative Review of Global Trends.

INTRODUCTION: Voluntary body donation (VBD) programs form the backbone of cadaveric teaching and learning in medical schools. It benefits the medical fraternity the most. Yet, there is a dearth of VBD practice among medical students. We aimed to understand the knowledge and attitude of first-year medical students in a tertiary institute with a systematic review of willingness toward VBD among undergraduate students worldwide. METHODS:  The first-year medical undergraduates were given a 12-item questionnaire to assess their knowledge and attitude toward VBD. Statistical tests were applied to analyze the difference between the variables. We systematically searched Google Scholar, PubMed, and SCOPUS databases until October 15, 2022. Data concerning knowledge, awareness, and attitude toward VBD among undergraduates of medical backgrounds were extracted and analyzed qualitatively. RESULTS: A total of 82.5% of students returned the completed responses. A significant association was seen between their attitudes toward whole body donation by strangers (p=0.043) and family members (p=0.035). The religion of the participants significantly affected their opinions on VBD and their willingness to pledge themselves (p=0.034). For the review, 20 studies were selected to be analyzed qualitatively. These studies included 4232 undergraduate students globally who were assessed for knowledge, awareness, and attitude toward VBD. Around 50% of the studies were published in India. The first study included was published in 2008. Seven studies were exclusively conducted on medical undergraduates, while the rest consisted of a mixed cohort. The attitude and knowledge of medical undergraduates on VBD were assessed via questionnaires containing both open-ended and closed-ended questions. CONCLUSION: Based on observations from our survey and review, we concluded that while undergraduate students have a highly positive attitude toward VBD, their rate of pledging is low. The most prominent barrier to this attitude is their experience with cadavers in the dissection hall. Hence, we recommend a revisit of cadaver handling practices and the establishment of appropriate protocols for safe and deferential cadaver handling.

A rare case of cavernous sinus thrombosis following oral squamous cell carcinoma - The etiology and management dilemma.

Intracranial cavernous sinus metastases of oral squamous cell carcinoma (OSCC) are rare, with a reported incidence of 0.4 %. Due to their extremely infrequent presentation the etiology and management modalities of such complications are not clearly represented in the literature. Here we present a case of a 58-year-old male diagnosed with OSCC of Right Lower Alveolus with underlying bone invasion, cT4aN1M0, Stage IV. He underwent Right Hemi-mandibulectomy with Modified Neck Dissection, Pectoralis Major Myocutaneous Flap, and 60 Gy/30# adjuvant radiotherapy. Six months later, the patient was diagnosed with recurrence involving the right infratemporal fossa with associated right cavernous sinus thrombosis. Immunohistochemistry block review showed PDL1 - Positive. The patient was subjected to Cisplatin and Pembrolizumab immunotherapy. After receiving 35 cycles of Pembrolizumab over a period of 2 years the patient is doing well with no recurrence.

Evaluation of undergraduate medical students' preference to human anatomy practical assessment methodology: a comparison between online and traditional methods.

PURPOSE: COVID 19 pandemic has brought crucial changes in the field of medical education. Ad mist university examinations in India medical schools have switched to online assessment methods to avoid student gatherings. In this context, we conducted online anatomy practical evaluation and we have aimed at quantifying the students' experience on virtual assessment. METHODS: A total of 250 first year MBBS students appeared for online anatomy practical examinations. Immediately after the completion of exams electronic feedback about their experience, in questionnaire format was obtained after getting informed consent. Their feedback was analysed and quantified. RESULTS: Completed feedback forms were submitted by 228 students. More than 50% of students favoured online anatomy spotter examinations. Only 32.8% of students were comfortable with soft parts discussion using images. For image based viva voce 61.4%, 80% & 82% of students responded that the features and orientation of osteology, radiology and embryology images, respectively, were good. For surface marking 55% of the participants preferred online verbal evaluation. Finally, more than 60% of the students preferred the conventional over online assessment methods. CONCLUSIONS: The inclination of students' preference for traditional anatomy examination methods mandates adequate training of both students and teachers for virtual examination. The superiority of conventional anatomy practical examination methods is unbiased but pandemic situations warrant adequate preparedness. In the future the anatomy teaching and evaluation methodology in Indian medical schools have to be drastically reviewed in equivalence with global digitalization.

Structural and functional significance of scrotal ligament: a comparative histological study.

Gubernaculum testes is the most important parameter in testicular migration. At the end of migration, it is described as scrotal ligament, which has implications in testicular torsion. The present study aims to examine the structure of scrotal ligament and compare it with gubernaculum. Sixteen adult cadaveric testicular specimens and fourteen fetal testicular specimens of different age groups were examined after getting ethical clearance from the institute ethics committee and consent from the parents. Meticulous dissection was done. The length, site of proximal, and distal attachment of scrotal ligament and gubernaculum were noted and histologically evaluated. A separate scrotal ligament could not be delineated in any adult specimens. It merged with testicular coverings. Histological examination showed the presence of patchy areas of dense collagen fibres of variable density amidst loose areolar connective tissue. In contrast, fetal specimens showed the presence of a definitive gubernaculum testes and revealed the presence of mesenchymal tissue, collagen, elastic fibres, and myocytes which varied according to gestational age of fetuses. Structure of scrotal ligament and gubernaculum testes is highly variable. Description of scrotal ligament as a firm attachment from lower pole of testes to scrotum is controversial, questioning its role as protective factor in testicular torsion.

Occipital meningoencephalocele with Cleft Lip, Cleft Palate and Limb Abnormalities- A Case Report.

A 21-week-old still born female fetus with occipital encepholocele, cleft lip and cleft palate was received from the Department of Obstetrics and Gynecology, Mahatma Gandhi Medical College and Research Institute, Pondicherry and was studied in detail. It was born to Primigravida, of a second degree consanguineous marriage, with unremarkable family history. The biometric measurements were noted which corresponded to the age of the fetus. Further the fetus was embalmed and dissected. On examination an encephalocele of 2.7×1.5 cm was seen in the occipital region with a midline defect in the occipital bone and herniated brain tissue. Other anomalies observed were right unilateral cleft lip, right cleft palate, and bilateral syndactyly of the lower limbs and associated Congenital Talipus Equino Varus of the right foot. Other internal organs were developed appropriate for the age of the fetus.

Skeletal muscle strength in young Asian Indian females after vitamin D and calcium supplementation: a double-blind randomized controlled clinical trial.

CONTEXT: Randomized control trials (RCT) of the effect of vitamin D/calcium supplementation on skeletal muscle strength have not shown promising effect in the elderly. OBJECTIVE: Our objective was to assess the effect of vitamin D and/or calcium on muscle strength in young adults with vitamin D deficiency. DESIGN AND SETTING: We conducted a RCT using a factorial design at a tertiary-care center from September 2010 to April 2011. SUBJECTS: A total of 173 healthy females with mean age, body mass index, and 25-hydroxyvitamin D [25(OH)D] of 21.7 ± 4.4 yr, 20.8 ± 2.96 kg/m(2), and 9.3 ± 3.37 ng/ml, respectively, were block randomized to 1) double placebo, 2) calcium/placebo, 3) cholecalciferol/placebo, and 4) cholecalciferol/calcium for 6 months. Cholecalciferol was given at 60,000 IU/wk for 8 wk followed by 60,000 IU/fortnight. Elemental calcium was given in doses of 500 mg twice per day for 6 months. METHODS: Assessment included hand grip (primary outcome) and pinch grip strength, distance walked in 6 min, dyspnea score, quality of life by Short Form (36) Health Survey (SP-36), serum 25(OH)D, 1,25-dihydroxyvitamin D, and intact PTH. RESULTS: The serum 25(OH)D increased significantly to 29.9 ± 8.35 and 27.0 ± 9.54 ng/ml in two groups on cholecalciferol. The mean hand grip strength (19.4 ± 3.92, 21.1 ± 3.31, 20.6 ± 3.92, and 20.1 ± 4.00 kg) and its increase from baseline (0.3 ± 2.25, 0.3 ± 2.64, -0.3 ± 2.41, and 0.6 ± 2.30 kg) were comparable in four groups at 6 months. Quality of life, urinary calcium/creatinine ratio, and adverse effects were also comparable in groups. CONCLUSION: Oral cholecalciferol/calcium supplementation in the dose/schedule used is effective and safe in increasing and maintaining serum 25(OH)D. However, this does not lead to improved skeletal muscle strength in young females.

Prevalence and progression of basal ganglia calcification and its pathogenic mechanism in patients with idiopathic hypoparathyroidism.

BACKGROUND: The pathogenesis of basal ganglia calcification (BGC) in hypoparathyroidism is not clear. Its occurrence in hypocalcaemic milieu of hypoparathyroidism is believed to be due to high serum calcium-phosphorus product and poor calcium control. OBJECTIVE: To report details of BGC in patients with idiopathic hypoparathyroidism (IH) and factors determining its progression during follow-up. METHOD: Clinical, biochemical characteristics and a meningioma-expressed antigen-6 (MGEA6) gene polymorphism were analysed in 145 patients with IH, recruited since 1998, to determine the factors associated with BGC. The progression of BGC and its relationship with metabolic control of serum calcium, phosphorus, serum 25(OH)D and 1,25(OH)(2) D were assessed after a mean of 6·9 ± 3·5 years in 49 of them. RESULTS: Basal ganglia calcification was present in 73·8% (95% CI: 66·6%-81·0%) of subjects affecting the globus pallidus (68·8%) putamen (55·9%) and caudate nucleus (54·8%). The other sites calcified were grey-white junction (39·8%), cerebellar parenchyma (31·2%), thalamus (29·0%) and dentate nuclei (24·7%). Parkinsonism and dystonic symptoms were present in three cases. The presence of BGC at presentation was associated with calcification of the choroid plexus, cataract and an increased risk of seizures but not tetany. The progression of BGC during follow-up was related to calcium/phosphorus ratio. For every 1% increase in this ratio, the odds of progression decreased by 5% (OR: 0·95, 95% CI: 0·93-0·99, P < 0·001). A MGEA6 polymorphism, serum 25(OH)D and 1,25(OH)(2)D did not affect progression of BGC. CONCLUSION: Basal ganglia calcification occurs in 73·8% of patients with IH and correlates with the duration of hypocalcaemia, choroid plexus calcification, seizures and cataract. The progression of BGC is related to the calcium/phosphorus ratio during follow-up. This brings forth the importance of adequate phosphorus control in the management of hypoparathyroidism.
