A combined course of primary health care practice and family medicine at the University of Gezira

The community-based course presented is a longitudinal course running through four semesters in the Faculty of Medicine, University of Gezira, Sudan. Students combine their regular work in primary health care centres with attachments to a number of families in Wad Medani town. They continue to visit these families regularly throughout their entire medical course with the aim of studying them and helping them with some of their medical and psychosocial problems.

Correlation between the intensity of cytomegalovirus infection and the amount of perivasculitis in aortic allografts

Abstract  We previously demonstrated that cytomegalovirus (CMV) infection enhanced perivascular inflammation in rat aortic allografts. In this study, we investigated the relationship between the CMV infection load and the magnitude of perivasculitis (chronic rejection) in aortic transplants. Rats received or-thotopic abdominal aortic grafts, different degrees of total body irradiation (TBI) for immunosuppres-sion and CMV inoculation. The spleens of the rats receiving 5 Gy of TBI contained more infectious virus and viral antigens than those of rats receiving 3 Gy of TBI or no TBI. Although the number of inflammatory cells infiltrating the perivascular area was decreased after TBI, CMV infection resulted in increased perivasculitis in rats that received 5 Gy of TBI as compared to non-infected animals. This virus-induced effect was characterized predominantly by an increased T-cell infiltration, including CD4 and CD8 T-cells. It is concluded that an enhanced systemic CMV infection during severe immunosuppressive therapy can accelerate the development of chronic rejection, which seems to be mediated mainly by T-cells.     

Understanding the pathologic Haglund's deformity

Pathologic conditions behind the calcaneus are common, and may initiate during early childhood. The authors discuss osseous and soft tissue conditions involving the posterior-superior surface of the heel. Radiographic and clinical evaluation is considered. Treatment alternatives are also reviewed.     

Long‐standing ulcerative colitis complicated by right subclavian artery occlusion and upper limbs arteriolitis with digital ischemia

A 48‐year‐old male patient with long‐standing ulcerative colitis since February 2001 which was diagnosed by endoscopy, developed acute digital ischemia affecting both hands with fixed colour changes in the left index finger which was followed shortly by digital ulceration. Magnetic resonance angiography (MRA) of both upper limbs showed evidence of vasculitis affecting digital arterioles on both sided and right subclavian occlusion. The patient received pulse methylprednisolone followed by cyclophosphamide pulse therapy, the latter continuing on a monthly basis for 6 months with appreciable improvement and remission of the vasculitic process; follow‐up MRA showed reperfusion of the previously occluded subcalvian artery. To the authors’ knowledge vasculitis complicating the course of ulcerative colitis is a rare association and is only sporadically reported in the literature. This rare entity should be diagnosed early and aggressively treated; MRA is a very promising diagnostic tool that is suitable for both diagnosis and follow‐up of patients with this rare entity.     

CO2 laser techniques in destruction of verrucae plantaris: discussion of the blister technique, a more complete method of wart ablation

The popular "Cross-hatch" method of CO2 laser surgery is compared with the "blister" technique of verrucae destruction. The blister technique provides greater reliability of wart tissue destruction through better visualization of normal skin lines and verrucoid tissue. The procedure can be performed quickly and easily, and is less painful to the patient than other conventional methods of wart destruction.
