Background: Sperm is more than just a mere transporter of paternal genetic information, although serving purposes other than conception. DNA integrity (DI) is regarded as a crucial aspect of semen quality and has great significance in predicting male fertility. Washing sperm is a form of preparation of sperm which is essential before processing intra-uterine-insemination since it removes chemicals from semen that might cause adversarial reactions in the uterus. During the process of washing, sperm gets separated from seminal fluid, which gradually improves the fertilizing capability of sperm, and numerous existing methods have faced complications with the determination of effective integrity in washing methods. The objective of the present study was to find the DI of the sperms through three washing methods that, include the density gradient (DG) method, swim up (SU) method, and magnetically activated cell sorting (MACS) method after the cryo-preservation (CP) for 3 months. Methodology: Semen samples were obtained from 40 oligoasthenospermic patients with progressive motility <32%, who underwent assisted reproductive technology procedure in Sumathi fertility center in Madurai between October 2021 and December 2021. Sperm washing is performed through three different mentioned techniques. The grades of the comet reflected five different classes from class 0 to class 4. These data were analyzed using one-way ANOVA test, and multiple comparisons were performed between these groups using Tukey's test. Results: The results showed a high level of normal sperm (68%) in the DG method than the SU (47%) and MACS (42%) sperm preparation techniques that specified by significant elevation (P < 0.001) of class 0 comet tails. Conclusion: It was observed that the DG method has the best and success rates for intracytoplasmic sperm injection and in vitro fertilization was relatively high.

Background: In the traditional method, students learn theory without contacting patients in the initial part of MBBS. Early clinical exposure creates a scope for students to correlate basic science and clinical application. Hence, there is a need to study the effectiveness of different forms of early clinical exposure (ECE). The objectives of the study were to compare the knowledge acquired and attitude toward ECE by the students after different forms of ECE. Methodology: An observational study was done with 1st-year MBBS (n = 150) students. Based on the National Medical Council (Then Medical Council of India) II ECE document for undergraduate medical education programs, 10 topics were selected. The first six ECE sessions were conducted in the classroom, the next two at the hospital, and the last two virtually. Phase-validated structured multiple-choice questions (MCQs) and feedback were given to students before and after every ECE. The MCQ scores and feedback conducted in three forms were statistically analyzed. Results: There was a notable disparity in the mean between pre- and posttest. The mean scores of the virtual mode were better than the other two forms. As per the feedback analysis, most of the students observed ECE aid to clear conceptualization, critical thinking, and correlate anatomical basis in clinical cases. However, students also felt that it is too early to understand the topic in such detail in 1st year. Conclusion: This longitudinal study on ECE showed there is an increase in the knowledge and analytical skills of students. Hence, we recommend continuing ECE and to have a blended learning environment along with limited content to be included for a better outcome.

Introduction: Histologically, the pineal gland shows pinealocytes, glial cells, and sometimes calcific concretions. Age-related changes in these three components have been reported by various workers. However, a statistically significant difference between the two sexes has not been found. This study was conducted to find out morphological and histological changes in human pineal gland in relation to advancing age and in relation to gender. Methodology: Forty pineal glands were taken for the study. The pineal glands were fixed in 10% formol saline and processed. Slides for microanatomical study were prepared and observed under microscope. Results: The size of the pinealocytes, size of their nuclei, and number of glial cells increased with age, but it was not significant. The number of pinealocytes decreased with age (P = 0.02). The size of the calcific concretions increased with age (P = 0.02). The difference in size of pinealocytes, nuclei of the pinealocytes, and the number of pinealocytes between genders was not significant. The difference in the number of glial cells between genders was significant (P = 0.03). The difference in the number of concentric lamellated type of calcific concretions between genders was significant (P = 0.03). Conclusion: A histological study of pineal gland in human is an area of interest for anatomists, radiologists, and neurologists. This study has paved a way for us for further research using immunohistochemistry and electron microscopy.

Background: Haglund's syndrome an important cause of posterior heel pain presents with a prominent bony contour, a retrocalcaneal bursitis or achillis tendinitis these can also occur in isolation hence for the diagnosis of etiology of Haglund's disease certain radiological parameters and soft tissue parameters have been created to evaluate the anatomical variations which will assist in its exact diagnosis. Study aims to distinguish between the bony and soft tissue causes of Haglund's disease radiologically. Methodology: After Institutional ethical committee clearance an observational cross-sectional study was conducted with subjects coming to radiology OPD for X-ray foot with complains of posterior heel pain fulfilling inclusion and exclusion criteria were examined for X-ray lateral view of foot. Parameters like calcaneal inclination angle (CIA), Fowler Philip angle (FPA), parallel pitch line (PPL), Steffenson & Evenson angle (SEA) measured, posterior/calcaneal spur and posterior calcaneal step were noted. The data obtained was analyzed for mean, Standard deviation, sensitivity % and false negative %. Result: Sensitivity of the parameters were analyzed to find CIA, SEA &PPL to be 63.3%, 55% and 55% sensitive respectively. CIA could be assigned most sensitive but regarding soft tissue parameters none were sensitive. Conclusion: CIA, SEA & PPL were found to be sensitive among bony parameters. But none of the soft tissue parameters were sensitive radiologically highlighting a need for its correlation with clinical symptom in peripheral health centers where MRI is not available. Sensitivity of bony and soft tissue parameters were analyzed to find CIA, SEA & PPL to be sensitive. CIA could be assigned most sensitive among bony parameter but with regards to soft tissue parameters none were sensitive.

In embryonic life developmental malformation of thoracic veins can lead to anomalies of the Superior vena cava and major thoracic veins like Azygos system. Double superior vena cava and double azygos vein are rare congenital anomaly with the incidence of 0.3%. These types of congenital anomalies may or may not be presented with clinical symptoms. This case was noted during the routine cadaveric dissection of thoracic region and heart for medical students in department of Anatomy, we found double superior vena cava (persistent left superior vena cava) along with double (paired) azygos vein in a female cadaver. Right superior vena was formed by the union of right subclavian and right internal jugular vein which receives the arch of right azygos before it opened into the right atrium. Left superior vena cava was formed by the union of left subclavian and left internal jugular vein and it also receives the arch of left azygos vein before it entered into the right atrium. In present case coronary sinus was separated from left persistent superior vena cava and it opened in the persistent left superior vena cava. There was no communication between both the superior vena cava. On right side Azygos vein was normal and open into right superior vena cava. On the left side hemiazygos was in continuation with the accessory azygos vein and it also forming the arch and opened into persistent left superior vena cava. There were no other congenital anomalies present in the heart. These types of congenital anomalies extremely very rare where the left superior vena cava opens into the right atrium directly and coronary sinus opens in to this left superior vena cava. Majority of such types of cases remain asymptomatic. Some cases may be detected accidently during diagnostic or surgical procedures like cardiac angiography, cardiac catheterization, by- pass and dialysis or during autopsy or institutional cadaveric dissection.

Background: The uniqueness of the human foot, in performing various functions, is intricately associated with different morphological parameters, and arch height index (AHI) is an important parameter for the same. The measurement of AHI has putative clinical implications in correcting the underlying causative factors, which contribute to foot pain. This study was an attempt to investigate these parameters as a correlation among asymptomatic versus patients complaining of foot pain (due to nontraumatic causes). Methodology: One hundred asymptomatic and 50 symptomatic adults were engaged in the study after taking prior consent. Various measurements (such as foot length, truncated foot length, foot breadth, arch height – [AH], and AHI) were taken in a standing position. In this study values of foot length, truncated foot length, foot breadth, AH and AHI were compared amongst the two groups . Comparison was done with earlier studies. Results: The difference in AH and AHI (P < 0.05) among the asymptomatic versus the foot pain patients, was significant. There was a considerable difference in body weight and Body Mass Index (BMI) affecting AH and AHI. AHI in the case of the symptomatic foot pain adults was 0.18 in both feet, with a standard deviation (SD) of 0.07. Conclusion: The AHI has been considered an essential parameter in defining and identifying the potential structural factors that predispose an individual to injuries of the foot. Our results indicate that the mean AHI in the case of foot pain adults (nontraumatic) was 0.18 in both feet, with an SD of 0.07. This is lower as compared to other studies. This can be attributed to the fact that earlier studies have been done on asymptomatic patients only. The present study was done to correlate between normal asymptomatic versus foot pain patients. There was a significant difference in the AH and AHI between our two study groups.

Background: Dorsalis pedis artery (DPA) is the chief artery of foot. It provides nutrition to the dorsum of the foot. Palpation of DPA is essential for the diagnosis of peripheral vascular diseases. Cutaneous flaps supplied by branches of DPA are used in various reconstruction surgeries. Methodology: 50 meticulously dissected lower limbs of both sides and known sex were observed for morphometry, asymmetry and sexual dimorphism of DPA and its branches. Variations like absent arcuate artery and extra lateral tarsal arteries were looked for. Results: Absent arcuate artery was seen in 12%. Three tarsal metatarsal arteries and two tarsal metatarsal arteries were seen in 4% and 16%, respectively. An extremely rare case of U-shaped loop joining two tarsal metatarsal arteries was seen in two limbs. Conclusion: Rare variations like multiple tarsal arteries joined by U-shaped loop and absent arcuate artery seen in our study are of importance for reconstruction surgeries using DPA flaps.

Background: First cervical vertebra has different anatomical features than other cervical vertebrae. It holds globe of skull and lacks body and spine. It is composed of 2 lateral masses linked by anterior and posterior arches. Posterior atlanto-occipital membrane is attached to posterior arch whose lateral edge sometimes ossifies thus converting groove into canal. Consequently, neurovascular groove gets converted into a bony ring “ponticulus posticus”. It can cause of neck pain and headache. Knowledge of this variation is important during various orthopedic procedures involving atlas including C1 lateral mass screw placement.Congenital defects of atlantal arch a developmental failure of chondrogenesis is a rare anomaly. These defects are a benign variation discovered incidentally. Detection of these anomalies is clinically important as they can cause acute neurologic deficits, which is associated with neck extension. Study was done: To determine the prevalence of Ponticulus Posticus and to report the frequency of various types of congenital malformations of the atlantal arch. Methodology: 250 computerized tomography (CT) head and neck in axial and sagittal sections from Picture Archiving and Communication System (PACS) of Dr RMLIMS, Lucknow was studied as CT is the best method to study the bony landmarks and any anomaly. Prevalence of variations was calculated. Data was analyzed statistically using SPSS version 21 by Chi-square test. Result: Prevalence of ponticulus posticus was 32.4%. Males had higher prevalence (20.4%) than females (12%). Incomplete ponticulus posticus (24.4%) was more than complete variant (8%). There was predominance of left sided ponticulus posticus(12% vs 8.4%) Deficient posterior arch was found in 9(3.6%) cases. 6 were of type A 3 were of type B. Conclusion: This study will help in determining cause of neurological deficit in patients due to presence of above variations.

Detection of these anomalies is clinically important as they can cause acute neurologic deficits, which is associated with neck extension. Study was done: To determine the prevalence of Ponticulus Posticus and to report the frequency of various types of congenital malformations of the atlantal arch. Methodology: 250 computerized tomography (CT) head and neck in axial and sagittal sections from Picture Archiving and Communication System (PACS) of Dr RMLIMS, Lucknow was studied as CT is the best method to study the bony landmarks and any anomaly. Prevalence of variations was calculated. Data was analyzed statistically using SPSS version 21 by Chi-square test. Result: Prevalence of ponticulus posticus was 32.4%. Males had higher prevalence (20.4%) than females (12%). Incomplete ponticulus posticus (24.4%) was more than complete variant (8%). There was predominance of left sided ponticulus posticus(12% vs 8.4%) Deficient posterior arch was found in 9(3.6%) cases. 6 were of type A 3 were of type B. Conclusion: This study will help in determining cause of neurological deficit in patients due to presence of above variations.","PeriodicalId":52750,"journal":{"name":"National Journal of Clinical Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45806569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anatomy reveals the human body and its architecture. Right from the intricate turn of an artery, loop of a duct, fold of the skin to the microscopic change in epithelium are studied through anatomy. These nuances are appreciated in a precise and accurate manner when a scalpel is laid on one's body. Today, learning anatomy complemented with new age techniques, enables us to visualize a structure along with their surrounding environment.
