Background: The paired parotid glands are the largest of the major salivary glands and produces mainly serous secretions. The secretion of this gland reaches the oral cavity through single parotid duct (Stensen’s duct). The parotid duct begins at the anterior border of the gland, crosses the masseter muscle, and then pierces the buccinator muscle to reach the mucosa lining the mouth at the level of the cheek. The purpose of this study is determine the morphologic features of the parotid duct and describe an anatomical variation until now unreported. Methods and Findings: A total of 17 cadavers were used for this study in the Morphology Laboratory at the University of Pamplona. In a cadaver were findings: The main parotid duct originated two conducts: Left superior parotid duct and Left inferior parotid duct, is observed the criss-cross of the ducts, and then perforated the buccinator muscle and entered the oral cavity at a double parotid papilla containing a double opening, separated from each other in 0,98 mm. In the remaining  33 parotid regions (97.06%) the parotid duct is conformed to the classical descriptions given in anatomical textbooks. Conclusions: The parotid duct anatomy is important for duct endoscopy, lithotripsy, sialography and trans-ductal facial nerve stimulation in the early stage of facial palsy in some cases. The anatomical variations also has clinical importance for parotid gland surgery and facial cosmetic surgery. To keep in mind the parotid duct variation will reduce iatrogenic injury risks and improve diagnosis of parotid duct injury.

Cervical vertebrae have a cardinal part that is a closeness of and through it passes the vertebral course, vertebral vein and sharp plexus of nerves. The vertebral course enters the of C6 and this way, the FT of C7, which transmits just the vein and nerve, might be near nothing or even occasionally absent. A vertebral channel may enter through C7 in 2% cases as necessities be combinations of this may affect the anatomical course of vascular and neural structures, and this way may cause over the top conditions. The explanation behind the investigation was to watch the anatomical mixes in the of seventh cervical vertebrae. Present work was carried on 156 dry seventh cervical vertebrae of cloud sex and age. We observed each for shape, symmetry, number or accessory and spicules. We observed nine different types of shape of . Round shapes of were present in 28.75 %, accessory in 28.84% and spicules in 12.17 % of vertebrae also noted incomplete FT in 5 vertebrae. Disclosures of present evaluation may be helpful for a radiologist in the comprehension of X-segments, dealt with and scans for spine specialists in preoperative arranging and for blocking injury of a vertebral vessel near to sharp nerves during the careful cervical approach.

Abstract Background and aim: The variations in the course and communicating branches of musculocutaneous nerve is of clinical importance in the treatment of recurrent compression neuropathies and in the diagnosis of median nerve lesions. Most of the reports on anatomical variations of musculocutaneous nerve are single case studies and such studies with emphasis on gender difference in a sample of Keralite population are rarely reported. The objective of the present study is to observe the variations in the course of musculocutaneous nerve with special reference to communications with other nerves of the arm and to study the correlation between gender and variations of the nerve. Materials and Methods: Two hundred and sixty four arms were dissected in the department of Anatomy, Government medical college, Thrissur and studied for variations of muculocutaneous nerve. Analysis was done with epi info, using proportions, confidence interval and Chi Square test. The communications noted were classified using the available classifications of Le Minor, Venieratos and Anagnostopoulou and Choi et al. Results: Nerve variations were seen in 24.2 % cases which include, absence of the nerve (3.4%), nerve not piercing coracobrachialis (12.4%) and communication to median nerve (15.1 %). All the variations observed were statistically not significant. The embryological basis for the axonal pathfinding is considered as a result of both guidance molecules and electrical activity that change the calcium homeostasis within the growth cone to regulate growth cone turning. Conclusion: Variations that were observed in the present study may give sufficient and relevant data on the nerves, among Keralite population in which studies are few.

Abstract BACKGROUND Many approaches are used for midline anterior cranial fossa meningioma resection. In the subfrontal approach, the anterior superior sagittal sinus (SSS) is commonly ligated to release the anterior falx. The transbasal approach allows access to the origin of the anterior SSS, allowing for maximum venous preservation. OBJECTIVE To investigate variations in the first and second veins draining into the SSS. METHODS We performed stepwise dissections for a transbasal level 1 approach on 8 anatomic specimens. We visualized the first and second veins draining into the sinus and measured the distance from the foramen cecum to these veins. We also measured the orbital bar height to determine the length of sagittal sinus that could be preserved with orbital bar removal. RESULTS The distance between the foramen cecum and the first vein ranged from 4 to 36 mm while the distance to the second vein ranged from 6 to 48 mm. The mean orbital bar height was 26.4 mm. Based on these measurements, with a traditional bicoronal craniotomy without orbital bar removal, 81% of first veins and 58% of second veins would be sacrificed. CONCLUSION A supraorbital bar or nasofrontal osteotomy, part of the transbasal skull base approach, is helpful to preserve the first and second veins when ligating the anterior SSS. Based on this study, it may be difficult to preserve these veins without orbital bar removal. Preservation of these veins may be of clinical importance when approaching midline anterior fossa pathologies.

Background: Variations in origin, course, branching pattern, termination and connections of the musculocutaneous nerve in the arm are not as uncommon as was once thought. Variational study of nerve in Nepalese is very less and can be of surigical-clinical importance. This opinion led us to performing this study. Objectives: The aim of this study was to a study in Nepalese which could be important for clinical investigation and the surgical treatment of peripheral nerve injury. Materials and methods: This study was carried out in Manipal College of medical sciences (MCOMS). Dissection of formalised 16 cadavers (n=32 upper limbs) were carried out using normal dissection kit with the help of standard dissection manual in two and half years. Results: The study revealed the variation in course, branching pattern and termination of musculocutaneous nerve in 6.25% of cases unilaterally on the right side. No statistically significant differences by gender and side were observed. Conclusion: This present study provides the evidence of variation of musculocutaneous nerve in Nepalese. The knowledge of the anatomical variations of the peripheral nerve system can help explain an incomprehensible clinical sign. Key words: Musculocutaneous nerve; Median nerve; Brachial plexus; Peripheral nerve repair. DOI: 10.3126/kumj.v7i4.2763 Kathmandu University Medical Journal (2009) Vol.7, No.4 Issue 28, 408-410

Background The clavicle is the most frequently fractured bone of the human skeleton. 70–80% of fractures occur at the middle third of the shaft of the bone. Anatomical variations in the clavicle of relevance to form intramedullary fixation. Objectives The purpose of this study was attempted to know about comparative differences between curvatures of the right and left clavicles, from certain metrical parameters. Methods The materials for the present study consisted of 257 (135 right and 122 left) adult clavicles, which were collected from the Department of Anatomy and from the students of the first year M.B.B.S during the period 2010 - 2011, Department of Anatomy, Kathmandu University School of Medical Sciences, Dhulikhel, Nepal. The deepest points of the curvatures of the clavicle, where the convexities were the maximum. These angles were measured with the help of a protractor. The sum of the two angles constituted the total curvature of the bone. Results The average medial angle, lateral angle and sum of the two angles of right side were 150.97º ±6.16 SD, 139.76º ±7.55 SD and 290.73º ±11.14 respectively and that of the left side were 151.50º ±5.67SD, 141.73º ±8.44 SD and 293.23º ±11.69SD respectively. The present study revealed that the medial and lateral angles of the left clavicle were greater than that of the right clavicle and medial curvature was more than the lateral curvature of the same clavicle. Conclusions It is important to recognize anatomical variations in the curvatures of clavicle when considering intramedullary nailing techniques. It also helps Anthropologists in their study of evolution.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6344 Kathmandu Univ Med J 2011;9(4):279-82

Muchos pacientes sufren de disfagia, vértigo, dolor en el brazo, entumecimiento o debilidad. Estos problemas pueden ser debidos a la aparición de osteofitos en las vértebras cervicales. El propósito de esta investigación ha sido estudiar las localizaciones y tamaño de los osteofitos en las vértebras cervicales. Se han usado 200 columnas cervicales (139 varones y 61 mujeres) de vértebras secas C3-C7, de un promedio de edad de 71 años (36-98 años). Se han encontrado osteofitos en 184 columnas (92 %), la mayoría en C5, C6, C4, C7 y C3 (83, 77, 74, 65 y 64%, respectivamente). La media del tamaño de los osteofitos en C3 (4.44 ±1.31 mm) ha sido mayor que los de C4-C7. La mayor cantidad de osteofitos se encontraron en los cuerpos vertebrales, carilla articular y foramen transverso (49,35 y 16%) respectivamente. La mayor longitud de los osteofitos en el cuerpo de las vértebras se encontraron en la vértebra fue 4.28 ±1.65 mmen C6, en la cara articular fue 5.07 ±1.57 mmen  C5 y en el transverso foramen fue  2.49 ±1.57 mmen C6. La longitud de los osteofitos del lado anterior superior y de la cara inferior del cuerpo ha sido más larga que la de los lados posterior y lateral. La longitud de los osteofitos muestra una correlación significativa y directa con la edad. Conclusión: Los osteofitos que han aparecido en el cuerpo de las vértebras, la cara y el foramen transverso pueden incidir en las estructuras cercanas. Este estudio puede ayudar a explicar algunos problemas clínicos como la disfagia, insuficiencia vertebrobasilar y braquialgia. Many patients suffer from dysphagia, vertigo, arm pain, numbness or weakness. These problems may arise from osteophytes in the cervical vertebrae. The purpose was to study the distribution and lengths of osteophyte in the cervical vertebrae. We used 200 cervical columns (139 male and 61 female) of dry C3-C7 vertebrae. Osteophytes were found in 184 columns (92%), mostly at C5, C6, C4, C7 and C3 (83, 77, 74, 65 and 64% respectively) . The average length of osteophytes of C3 (4.44 ± 1.31 mm) was longer than those of C4-C7. The quantity of osteophytes mostly was found at vertebral bodies, articular facets and transverse foramen (49, 35 and 16%) respectively. The greatest osteophyte length of vertebral bodies was at C6 (4.28 ± 1.65 mm.), that of articular facet was at C5 (5.07 ± 1.57 mm.) and that of foramen transversarium was at C6 (2.49 ± 1.57 mm.). The osteophyte length of anterior area of superior and inferior surface of body was longer than posterior and lateral area.  The osteophyte length was significantly correlated with age. Conclusion: The osteophytes that occurred at vertebral bodies, facet and transverse foramen may impinge on nearby structures. This study may help in explaining some clinical problems such as dysphagia, vertebrobasilar insufficiency and brachialgia.

The church burials of Room-94 and Church-79 as well as the Tower 35-Tomb were excavated within the ancient Byzantine settlement in Khirbet es-Samrā, North Jordan. They were initially dated between the 7th and 9th centuries AD. The report provides the results of macroscopic analyses of the obtained human skeletal remains. These include demographic, anthropometric, epigenetic, and pathologic features. The available biological and archaeological evidence tend to suggest that the five adults and child buried in Room-94 tomb were related males, possibly of one local and highly positioned family that was associated with the adjacent Church 95. The six were successively buried in the “private” tomb in Room-94 of Church-95 and not in the “public” cemetery just outside the settlement. The two probable cases of brucellar lesions on the cervical vertebrae of two adults could be indicative of an animal breeding family and that dairy products were part of the local diet. The report also suggests a possible relatedness between Room-94 tomb burials and the 7th century AD senile female burial in Church-79, which was previously assumed to be a male church-functionary burial. Despite being marked by a cross-engraved stone and a probably lethal arrow injury, the available evidence lead to conclude that the male Tower burial, previously identified as of the 9th century AD, was in fact a medieval burial and that it is neither related to the ancient settlement nor to its ancient population. Also presented are some rarely reported biological features, e.g. the “en bloc” manifestation of the transverse foramen division on the cervical vertebrae C5 to C7. Keywords: Jordan - Byzantine Period - Church Burial – Anthropometry - Epigenetics- Paleopathology.
