Background: The present study was conducted for analysis of the morphometry shape and determination of sex by foramen Magnum. Methods: After applying inclusion and exclusion criteria 30 dried human skull of unknown age and sex were slected for present study from the Department of anatomy, S.M.S. Medical College, Jaipur, Rajasthan. In case of skull bones, all 30 cranial bases were visually assessed for FM shape classification. Each FM shape was classified into one of the 8 types: oval, egg, round, tetragonal, pentagonal, hexagonal, combination of 2 different semicircles and irregular. Results: The mean anteroposterior diameter of foramen magnum male and female skull bones were found to be 37.17±1.76 mm  and 33.92±3.50 mm respectively.The mean transverse diameter of foramen mgnum in male and female skull bones were found to be 29.49±2.68 mm and 29.38±2.47 mm respectively.The mean area of foramen magnum male and female skull bones were found to be 818.05±119.66 mm² and   847.57±105.85 mm² respectively.The mean index of foramen magnum in male and female skull bones were found to be 84.00±5.41 and 80.27±5.79 respectively.Overall skull bones showed a medium type of foramen magnum index . Conclusion: We concluded that the several anatomic parameters such as shape and dimensions of foramen magnum should be taken into consideration during surgery involving the craniovertebral junction. Also these can be used during forensic and anthropological investigation of unknown individuals for determining gender, ethnicity, etc Keywords: Skull, foramen magnum, skull.

The aim of the article is to the determination of transverse diameter and longitudinal axis in patients with cholecystitis and with the help of CT scan in the north Indian population for the estimation of epidemiology. Patients with cholecystitis and of ages between 17-80 years irrespective of gender were included in the study (cases). All patient's cases (100) and controls (100) were advised the night before that did not eat or drink. Control groups (Normal Gallbladder) were collected when patients are comprised of other abdominal disease diagnosed by computed tomography. The mean age of controls and cases was 47.24±11.57 and 45.20±16.22 years, respectively studied by computed tomography. More than half of cases (62%) and 50% of controls were females. The transverse diameter was significantly (p=0.0001) higher among cases (36.42±15.52 mm) than controls (24.12±9.11 mm) studied by computed tomography. Longitudinal axis was significantly (p=0.0001) higher among cases (33.23±14.73 mm) than controls (21.75±8.69) studied by computed tomography. Transverse diameter>25 correctly predicted cholecystitis and by CT in 38.5% cases with sensitivity and specificity of 77% (95%CI=68.8-85.2) and 74% (95%CI=55.7-74.3%) respectively. Longitudinal axis >25 correctly predicted cholecystitis and by CT in 34.5% cases with specificity and sensitivity of 69% (95%CI=59.9-78.1) and 71% (95%CI=62.1-79.9%) respectively. We concluded in this study, increased transverse diameter and longitudinal axis were observed. Good sensitivity and specificity of these two parameters were also found in predicting cholecystitis and by computed tomography. All such cases should be subjected to biopsy for examination to rule out the gallbladder carcinoma for better prognosis.

Cephalometry deals with measurement of body parts or radiological specimen. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica were reported. In this study, using computerized tomographic (CT) scans from a tertiary hospital, one hundred and seventy five (175) scans were analyzed using Radiant version 4.2 (Medixant 2017) for determination of sizes and shapes of the sella. Average dimensions from the study include: Length (12.4 mm), A-P diameter (14.1 mm), depth (9.6 mm) and transverse diameter (13.8 mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). In another classification of shape variation, the findings are: Normal (68.6%), anterior oblique (9.1%), pyramidal (6.9%), double contour floor (5.7%), notching on the posterior wall (5.1%) and sella bridge (4.6%). Males tend to have higher sella sizes than females and there is statistical significant difference between them especially in respect to A-P diameter and length parameters. However, there is no sex predilection to shapes.

[Abstract]BackgroundSacrum being a part of pelvis is an important bone for identification of sex in both living primates and fossil ones.AimAim of this work was to examine the sex differences of sacral parameters in rhesus macaques and to compare with those of the other primates.Materials and MethodsFifty-six adult scara of macaques (17 males and 39 females) have been investigated. Measurement of various parameters was done using sliding vernier calliper; and statistical analysis was done using SPSS 23.0 package.ResultsThe present study showed that the cranial breadth of the sacrum, the sacral length, transverse diameter and sagittal diameter of the cranial articular surface, and two indices of relative sacral breadth were highly significant for sex determination in Macaca mulatta. Comparison of the present data with other studies suggest that sex determination of sacrum can be very different in various types of primates.ConclusionThe results suggest that these measures may be functionally integrated in response to locomotion, obstetric adequacy and cephalopelvic proportions in primates. Sacral index is more reliable and should be applied for sex determination of sacrum in various anatomical and anthropological investigations.

Background: Sex classification of a bone is possible with a degree of certainty only if it can be compared to a series of bones of known sexual dimorphism. Different parameters and indices are available based on which the sex can be determined using sacrum. Thus, it always attracted the attention of the medico-legal experts for establishing the sex, because of its contribution to pelvic girdle and associated functional sex differences. Objective: Study the sexual dimorphism and regional differences of the varied features of the sacrum in West Bengal population and compare the significant anthropometric indices with similar observations across India. Material and method: The study comprised of 50 adult sacra (35 male and 15 female), obtained from the department of anatomy and department of forensic medicine of ICARE Institute of Medical Sciences and Research and Haldia Institute of Dental Sciences and Research, Haldia, West Bengal. Different parameters viz. mid ventral straight length, mid ventral curved length, ventral straight breadth, transverse diameter of base, transverse diameter of body of S1, antero-posterior diameter of body of S1, breadth of alae were measured and indices viz. sacral index, longitudinal curvature index and corporobasal index were calculated and statistically analyzed. Result: Sacral index was found to be the most useful criterion for identification of sex followed by breadth of alae, corporobasal index and the ventral straight breadth. Conclusion: In the present study, out of the eleven parameters of the sacrum, seven parameters yielded statistical significance between the two sexes. Therefore, it can be concluded that sex determination of the sacrum with 100% accuracy may possible only when maximum number of parameters are taken into consideration.

The present study investigated the maneuverability and reasonability of sensory analysis, which has been applied in TCM identification for a long time. Ten assessors were trained and generated the human panel to carry out the organoleptic evaluation of twenty-five batches of Sha-Ren samples. Accordingly, samples were scored from 0 (lowest) to 10 (highest) for sensory attributes. Based on this, samples were divided into three classes: high class (Yang-Chun-Sha from Guang-Dong), moderate class (Yang-Chun-Sha samples from Yun-Nan and Guang-Xi), and low class (Lv-Qiao-Sha from marketplaces). For further background, three instrumental approaches were employed: morphological measurement with three indices (longitudinal diameter, transverse diameter, and 100-fruit weight), GC for determination of bornyl acetate contents, and E-nose for aromatic fingerprint. It is demonstrated in the results that GC and E-nose analyses were in great agreement with organoleptic evaluation. It gives insights into further studies on searching better morphological indicators and improving discriminant model of E-nose.

Cephalometry deals with the measurement of the head or radiological specimen of the head. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica have been reported. However, in this study, using computerized tomographic (CT) scans, one hundred and seventy-five (175) scans were analyzed using Radiant version 4.2 for determination of sizes and shapes of the sella. Average dimensions from the study include length (12.4mm), A-P diameter (14.1 m), depth (9.6 mm) and transverse diameter (13.8mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). Males tend to have higher sella sizes than females and there are statistically               significant differences between them especially in respect to A-P diameter and length parameters. Also, there is a statistically significant relationship between age groups in terms of A-P diameter and depth of the sella turcica. However, there is no correlation between age and shapes found in the study.

ABSTRACT X-ray pelvimetry of 156 pregnant diabetic women showed a significantly positive correlation between the transverse diameter of the pelvic inlet and age at diagnosis of diabetes. Compared with the pelvic measurements in a control group of 50 nondiabetic, puerperal women, the transverse diameter of the pelvic inlet was significantly shorter among diabetic wcmen whose diabetes had set in before the age of 13 and significantly longer among diabetic women whose diabetes had been diagnosed after the age of 21. The shorter transverse diameter of the pelvic inlet in women with early-onset diabetes is related to the diabetic disease. The changes are non-specific, and their cause is unknown. The pelvic changes may contribute to the frequently complicated course of delivery in these women.

Objective: A clear knowledge of the location of supraorbital foramen (SOF) is vital for the surgeons, particularly in endoscopic surgery and regional block in crania. The aim of this study was to analyze SOF and notch in skulls of various ancestries. Methods: The anatomical variations of SOF and notch were examined in 100 adults skulls (55 males and 45 females) of the Malay, Chinese, and Indian ancestries by traditional measurement made with the Osirix software. The parameters included distance between supraorbital structure and nasal midline, shape, and transverse diameter of the SOF. Results: It was manifested that bilateral supraorbital notch (SON) was the most prevalent combination in both sexes and ancestries (61%), while combined SON and foramen (11%) were the least prevalent characteristic. The mean distances of supraorbital structure from nasal midline bilaterally in males were slightly greater than females. The horizontal diameter of SOF, notch and their distances from the nasal midline showed no difference between ancestries. Conclusion: This study would serve as a guide for the surgeons when surgery is performed on the scalp. It can help in the precise determination of reference points for supraorbital nerve blockade for the Malaysians. In addition, the variations exhibited in supraorbital measurements inevitably revealed that sex and ancestry should be taken into consideration when choosing samples for anatomical classification of crania.
