Though ulnar arterial variations are rare, superficial ulnar artery (SUA) is one of its commonest variations. During routine dissection in our department, we observed a unilateral case of SUA in a 70-year-old male human cadaver. It originated from the left brachial artery in the middle of the arm, 13cm above the medial epicondyle of humerus (15cm below the outer margin of first rib). From its origin, it passed downwards in the medial part of arm and forearm in a superficial plane compared to normal ulnar artery. In the hand, the SUA anastomosed with the superficial palmar branch of the radial artery, creating the superficial palmar arch. The superficial palmar arch gave additional branches to the thumb and index finger. Brachial artery divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. The existence of a SUA is undeniably of interest to the clinicians as well as to the anatomists. We hereby present a case of unilateral SUA along with a brief review of the literature and analysis of its clinical significance.

Facial vein, being the largest vein of the face forms the common facial vein after joining with the anterior division of
retromandibular vein below the angle of the mandible. Usually, it drains into the internal jugular vein. During
routine dissection of head and neck region of a male cadaver, aged approximately 50 years, an unusual pattern in the
termination of veins on the left side of the neck was observed. The formation, course and termination of external
jugular vein were normal. The anterior division of retromandibular vein joined with external jugular vein about 5 cm
above the clavicle and the facial vein opened into the external jugular vein about 2.5 cm above the clavicle. In
addition, there was a thin venous communication between anterior division of retromandibular vein and external
jugular vein. The superficial veins of the neck are often used for cannulation; either for intravenous infusion or for
central venous pressure monitoring. Furthermore, these venous segments are used as a patch for carotid
endarterectomies. Hence, a thorough knowledge of the normal anatomy and their variations may be useful for
performing these procedures.

Facial vein is the main vein of the face. Though its origin is constant, it frequently shows variations in its termination. We report a rare type of variation of facial vein. The right facial vein coursed transversely across the masseter, superficial to the parotid duct and entered into the substance of the parotid gland, at its anterior border. Deep dissection of the gland revealed the abnormal termination of facial vein into the superficial temporal vein. The transverse facial vein drained into the facial vein. The superficial temporal vein after receiving the facial vein continued as retromandibular vein. Knowledge of this anomalous course and termination of facial vein may be important for the surgeons doing parotid, maxillofacial and plastic surgeries.

BACKGROUND AND OBJECTIVES: The purpose of this first of its kind study was to analyse the growth, development and attachment of cultured human umbilical cord stem cells alone or supplemented with basic Fibroblast Growth Factor (bFGF) on both healthy and periodontally diseased tooth surfaces in vitro. METHODS: Four groups of 12 root surface scaffolds each were classified as Group I- healthy root surfaces; Group II- periodontally diseased; Group III- Healthy with bFGF and Group IV- periodontally diseased root with bFGF. bFGF was applied in the concentration of 8 ng/ml on to the surface followed by incubation of cultured human umbilical cord stem cells (hUCMSCs) on the scaffolds. Scanning electron microscopy observations were made on 14th and 21st days to assess the proliferation and morphology of cells attached on the tooth surface. RESULTS: Cultured hUCMSCs demonstrated adhesion to tooth root scaffold. All the groups showed a significant increase in the number of cell attachment from 14th day to 21st day. The groups with bFGF showed a significant increase in attachment of cells when compared to the groups without bFGF. The cells showed an increase in number of flat cells from 14th day to 21st day in all the groups indicating an increased maturity of cells. Periodontally diseased groups had less maturity of cells than healthy groups. The groups supplemented with bFGF, had more mature cells than the groups without bFGF. CONCLUSIONS: hUCMSCs have the propensity to differentiate into cells that have the capacity to bind to root surfaces. hUCMSCs incubated with bFGF showed better proliferation and attachment to tooth root surfaces. The role of hUCMSCs can be further explored for periodontal regeneration.

Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vessels at the hilum of the kidney. During routine dissections, a variation in the branching pattern of the right renal artery was noted in an adult male cadaver. The right renal artery divided into upper and lower divisions 6cm away from the hilum of the kidney. The upper division gave 4 branches, and the lower division gave two branches. These two branches further bifurcated and gave 2 branches each. Thus, there were 8 prehilar branches of renal artery. The multiple prehilar branches led to a congested atmosphere at the hilum of the kidney. This arterial congestion might result in hindering the blood flow at the renal hilum. Apart from this, it might cause difficulties in diagnostic and therapeutic invasive procedures. Knowledge of this variation is of importance to radiologists and urologists in particular.
