Abstract:Commonest cause of axillary nerve lesion is trauma. Many workers have studied the safe area for axillary nerve by measuring its distance from various landmarks. Sixty formalin fixed cadaveric shoulders were dissected. After proper exposure of axillary nerve and acromian process of scapula, distance of axillary nerve was measured from lateral edge, anterior and posterior edge of acromian process in neutral position. Distance was noted in adduction and abduction. Arm length and full arm length were measured. Mean, standard deviation, range was calculated. Mean distance of the nerve in neutral position was compared to the arm length and the full arm length using SPSS 11 software.
Keywords:Acromian process, Axillary nerve, nerve injury, Shoulder surgery

Abstract:A carotid body tumour is a rare presentation of an extra-adrenal pheochromocytoma which typically present as a slow growing, painless neck mass found along the anterior border of the sternocleidomastoid muscle, and careful preoperative evaluation is required to find out the functional and vascular status of these tumours. Carotid body paragangliomas were diagnosed by Doppler ultrasound, carotid artery angiography, cranial computed tomography and magnetic resonance imaging. These tumours are generally benign but possess aggressive local growth potential. Therefore, definitive treatment requires surgical resection. Here we describe a case of a carotid body tumour in a 45-year-old female presenting with a neck mass, its evaluation, management and the final outcome and review the most recent literature on this unusual topic.

Abstract:Fertility is an important predictor of maternal mortality: high fertility levels being associated with high maternal mortality. Factors like use of contraception, fertility preferences are empirically shown to influence fertility levels. Choosing a method of birth control, its effectiveness and safety are the key considerations. Objectives of the study were to determine the proportion of women using hormonal and non-hormonal contraceptive methods among modern contraceptive users and to determine factors associated with use of hormonal and non-hormonal contraceptive methods.
