A CADAVERIC STUDY ON THE ANATOMICAL VARIATIONS OF THE MUSCULOCUTANEOUS NERVE IN RELATION WITH MEDIAN NERVE AND CORACOBRACHIALIS MUSCLE

Musculocutaneous nerve is derived from the lateral cord of brachial plexus and supplies the muscles of the arm. Initially the nerve accompanies the lateral side of third part of axillary artery and then pierces the coracobrachialis muscle after supplying it, passes downwards and laterally in between biceps brachii and brachialis sending branches to both and continues as lateral cutaneous nerve of the forearm. Variations ofmusculocutaneous nerve is important for surgeons, orthopedic surgeons and traumatologists, so a detailed cadaveric study of musculocutaneous nerve was done to observe the variations.Material & Methods: Musculocutaneous nerve was studied in 50 human cadavers (30 males and 20 females) of age group 40-60 years at Department of Anatomy, Subharti Medical College, Meerut, India.Results: Musculocutaneous nerve was present in all the cases and was piercing the coracobrachialis muscle. In 4% of the cases, the nerve was rejoining the median nerve after piercing the coracobrachialis.

MORPHOLOGICAL STUDY OF VARIATIONS IN FORAMEN TRANSVERSARIUM OF ATLAS VERTEBRA

Foramen transversarium are the characteristic bony feature of the cervical vertebrae. They are located on the transverse process of cervical vertebrae through which second part of vertebral artery passes along with vertebral venous and sympathetic plexus. Their variations are common with regard to size, shape,incomplete, duplicated and may even absent.Material & Methods: Two hundred foramen transversarium of one hundred atlas vertebrae were examined for morphological variations.Results: Out of hundred atlas vertebrae examined, foramen transversarium was present in all. Absence of costal element was noticed in four atlas vertebrae. Four atlas vertebrae showed incomplete bilateral foramen transversarium while four showed unilateral duplicated foramen transversarium.Conclusion: The increasing incidence of neck injuries and related syndromes necessitates the study of bony variations of the atlas vertebra and its foramen transversarium. The second part of vertebral artery is prone to be damaged during neck surgeries and posterior cervical injuries due to incomplete formation of the foramentransversarium, hence the knowledge of such variations is important for surgeons, otorhinolaryngologists, neurologists, orthopedicians, radiologists and physicians.

DUALS OF A FRAME IN QUATERNIONIC HILBERT SPACES

Frames in a separable quaternionic Hilbert space were introduced and studied in [17] to have more applications. In this paper, we extend the study of frames in quaternionic Hilbert spaces and introduce different types of duals of a frame in separable quaternionic Hilbert spaces. As an application, we give the orthogonal projection of $\ell^2(\HH)$ onto the range of analysis operator of the given frame, in terms of elements of canonical dual frame and elements of the frame in quaternionic Hilbert space. Finally, we give an expression for the orthogonal projection in terms of operators related to the frame and its canonical dual frame in quaternionic Hilbert space.

Erythema nodosum leprosum (ENL) mimicking Pityriasis lichenoides et varioliform acuta (PLEVA): An atypical presentation

Erythema Nodosum Leprosum (ENL) or Type 2 lepra reaction is found in the lepromatous pole of leprosy. It usually presents as tender, erythematous, evanescent nodules associated with systemic features. Besides nodular lesions, various reported atypical presentations of ENL include pustular, bullous, ulcerated and erythema multiforme-like lesions. Atypical presentations often lead to delay in diagnosis and treatment which may lead to severe systemic complications in ENL. We are reporting a 50 year old male who presented with recurrent papular and pustular crusted skin lesions associated with mild fever and was misdiagnosed as PLEVA initially, but later on was proved to have lepromatous leprosy with erythema nodosum leprosum on histopathology.
