الوصف: Background: Knowledge of the variant anatomy of the brachial artery is important in radial arterial grafts for coronary bypass, percutaneous trans-radial approach to coronary angiography, angioplasty and flap surgery. These variations show ethnic differences but data from black populations are scarce. This study therefore describes the course in relation with median nerve, level and pattern of termination of brachial artery in a black Kenyan population. Methods: This was a cadaveric dissection study of 162 upper limbs at the Department of Human Anatomy University of Nairobi, Kenya. The brachial artery was exposed entirely from the lower border of teres major to its point of termination. The course in relation to the median nerve and the level of termination were recorded. The results were analyzed using SPSS version 17.0 for Windows. Results: 72.2% of the brachial arteries followed the classical pattern described in Gray’s Anatomy. Superficial brachioradial and superficial bra- chial arteries were present in 12.3% and 6.1% of the cases respectively. Brachial artery terminated at the radial neck in 79% of the cases, radial tuberosity (8.6%), and proximal arm (11.1%), mid arm (1.2%). Pattern of termination was either a bifurcation into the radial and ulnar arteries (90.1%) or trifurcation into radial, ulnar and common interosseous arter-ies (9.3%). We also report a case of trifurcation of the brachial artery into the profunda brachii, radial and ulnar arteries (0.6%). Conclusion: Variations of the brachial artery in its relationship with the median nerve, level and pattern of termination are common. These may complicate arm surgical exposures, flap and vascular surgery. Pre-opera-tive angiographic evaluation is recommended.

الوصف: Gastrointestinal tuberculosis is common in Africa. Nonetheless, isolated duodenal involvement is rare, and is more likely to mimic other causes of duodenal obstruction. We report a patient who succumbed to an isolated mid duodenal tuberculosis, diagnosed at laparatomy, whose clinical presenta-tion, endoscopy and computerised tomography scans resembled annular pancreas. The limitations of clinical evaluation, endoscopy and radiology are highlighted as the importance of diagnostic laparoscopy is emphasized.

الوصف: Background Accurate evaluation of low back pain is essential for its rational manage-ment. The extent of use of clinical and imaging findings in identification of prolapsed intervertebral disk varies between centers. In Kenya, the diagnostic procedure is obscure. Objective To assess the evaluation of low back pain patients for prolapsed inter-vertebral disk at Kenyatta National Hospital, a teaching and referral hospital in Kenya. Study Design A retrospective chart study Patients and Methods Historical, physical and imaging findings of patients who presented with low back pain and subsequently diagnosed with prolapsed inter-vertebral disk between Jan 1997 and December 2007 were evaluated. Results Of the six hundred and three patients (267 males, 336 females) who were evaluated, risk factors were recorded in 39.5% patients, 35.3% patients had sciatica while straight leg raising test was performed in 52.2% patients. Investigations performed in these patients included plain roentograms (38.5%), CT scan (9.1%) and MRI (44.1%). Conclusion The evaluation of low back pain for prolapsed inter-vertebral disk was incomplete. History of sciatica, SLRT, crossed SLRT and MRI use are recommended for routine evaluation of low back pain for PID.

مصطلحات موضوعية: Saphenous, Varicose Veins
الوصف: p. 418 - 421 ; Lower extremity venous insufficiency is a common condition and increases with age. In addition to classical symptoms, it may result in skin changes and venous ulcers . I his disease has a great impact on the patients' quality of life and is associated with considerable health care cost. We assessed the age distribution, mode of presentation and management of saphenous varicose veins in a Christian Mission Hospital in Kenya. Forty adult patients (26 females and 14 males) with a diagnosis saphenous varicose vein at PCEA Kikuyu Hospital were evaluated. The patients' bio data, presenting complains, investigations, management and outcome were noted. The data collected was analyzed for means and variances using the SPSS version 17 for Windows and represented using charts and graphs. Most varicosities were bilateral and affected both the thighs and legs. Six patients were pregnant while 15% of the patients presented with venous ulcers. Most (90%) ulcers were found in the elderly patients. Saphenous varicose veins are common in the Kenyan population. Lack of adequate public education predisposes the elderly in the community to are presentation of saphenous varicose veins with ulcers

مصطلحات موضوعية: Recurrent hip dislocation, Labrum avulsion
الوصف: Recurrent traumatic hip dislocation in adults is very rare. It is often associated with fractures of the acetabulum wall and or column. There have been very few cases of recurrent traumatic hip dislocation secondary to avulsion of the acetabular labrum. We report a patient with traumatic recurrent posterior hip dislocation who had acetabular labrum avulsion, with torn short external rotators, who benefitted from surgical repair of the labrum, with plate augmentation. Clinicians should be wary of post traumatic labral tears as a rare cause of recurrent posterior hip dislocation in the absence of acetabular fractures. They are amenable to surgical repair.Key words: Recurrent hip dislocation, Labrum avulsion

الوصف: Experience in maintaining excellence in teaching of human anatomy is important in informing strategies to mitigate worldwide decline in the level of knowledge of human anatomy among medical students and qualifying doctors. Factors responsible for the decline include reduction in teaching time, inadequate teachers and undermining of cadaver dissection. Measures to address these challenges have resulted in wide disparities in curriculum design teaching methods, number and composition of instructors. Inspite of the challenges, the Department of Human Anatomy of the University of Nairobi (UON) maintained excellence of teaching for over 40yrs. This article describes the teaching of anatomy at the UON with a view of elucidating the learning points from which other departments can learn. Analysis reveals that human anatomy is allocated 630hrs per year of which 350hrs are allocated to gross anatomy with 270hrs devoted to dissection. Although dissection has remained the cornerstone of instruction, it is combined with clinically oriented problem based instruction, use of prosections, diagnostic imaging, computer aided and small group learning. Teaching of gross anatomy is integrated with microscopic, developmental and neuroanatomy. The department runs and intercalated Bachelor of Science (B.Sc.) anatomy degree which is a reliable source of members of staff. Over 70% of the staff are surgeons. They are assisted by demonstrators drawn from trainee surgeons and young B.Sc. Anatomy graduates. Excellence in teaching anatomy can be maintained by reclaiming sufficient teaching time, combined dissection with contemporary methods of instruction, integrating gross, microscopic, developmental anatomy, neuroanatomy, involvement of clinicians in teaching, commencing training anatomy early and engagement of demonstrators.Keywords: Anatomy teaching, University of Nairobi

مصطلحات موضوعية: internal carotid, topography, landmarks
الوصف: We studied the extra cranial portion of the internal carotid artery and structures associated with it, which are vulnerable to iatrogenic injury during surgical approach to the neck region in 18 individuals. Distances from the origin of the artery to hypoglossal nerve and posterior belly of digastric muscle were measured. The mastoid process and the hyoid bone were also used as landmarks in locating the nerve and respective distances measured. Hypoglossal nerve and posterior belly of digastric muscle crossed the ICA at variable positions with a mean distance of 10.1mm and 17.9mm respectively from the common carotid bifurcation. From the mastoid process, the internal carotid artery ascends underneath the posterior belly of the digastric muscle a third the distance to the hyoid bone. The external carotid artery is located lateral to the internal carotid artery in 63.8% of the cases, posterior in 16.7% and anterior in 19.4%. The posterior belly of digastric muscle and its attachments are key landmarks in identifying the internal carotid artery and thus avoiding injury to vital neurovascular structures which may help structures, which may help, improve clinical outcomes during surgery.Keywords: internal carotid, topography, landmarks

مصطلحات موضوعية: Common carotid, Trifurcation, Quadrifurcation, Pentafurcation, African, Ascending Pharyngeal, Occipital, Posterior auricular arteries
الوصف: Knowledge of variant termination of common carotid artery is important to prevent inadvertent vascular injury during surgical, interventional and diagnostic radiological neck procedures. The variations show population differences but there are scanty data from the black African populations. Further, though trifurcations have been reported, quadrifurcations and pentafurcations are hitherto undocumented. This study therefore examined the pattern of termination of 208 left common carotid arteries in the black Kenyan population by cadaveric dissection at the Department of Human Anatomy, University of Nairobi. The conventional bifurcation into internal and external carotid arteries occurred in only 128 (61.5%) of cases. Trifurcation occurred in 66 (31.7%), quadrifurcation in 11(5.4%) and pentafurcation in 3 (1.4%). In all cases of trifurcation, superior thyroid artery was the third branch. The common carotid artery quadrifurcated into external, internal carotid, superior thyroid and ascending pharyngeal arteries. The pentafurcations comprised internal carotid, external carotid, superior thyroid, occipital and posterior auricular arteries. These findings imply that the black Kenyan population has over 38% frequency of variant termination of common carotid arteries comprising trifurcation, quadrifurcation and pentafurcation which may complicate radical neck dissection, vascular surgery, carotid catheterization and selective embolization. Surgeons and radiologists should approach the common carotid bifurcation with extra caution.Keywords: Common carotid, Trifurcation, Quadrifurcation, Pentafurcation, African, Ascending Pharyngeal, Occipital, Posterior auricular arteries

مصطلحات موضوعية: Foramen magnum, variations
الوصف: Foramen magnum is a useful landmark in the base of the skull. Its shape and dimensions show ethnic and gender differences. This data is useful in forensic medicine and anthropology but are unknown among Kenyans. Two hundred and two dry adult skulls from the Osteology Department at the National Museums of Kenya, were studied. The shape of the foramen magnum was oval, circular and polygonal in 13%, 24% and 63% of the cases respectively. The foramen magnum does not show sexual dimorphism in shape among Africans. The shape of foramen magnum cannot be used in solitude to ascertain the gender of skulls.Keywords: Foramen magnum, variations
