Background: Cancer is a major health problem in developed countries and epidemiological evidence shows the emergence of a similar tend in developing countries, particularly in sub-Saharan Africa where HIV/AIDS is predicted to augment the cancer burden. The present study analyses the profile of cancers recorded in the first decade (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004) of establishment of the Kano cancer registry (KCR) a histology/ cytology-based registry in Kano, Nigeria. Methods: Records of cancer cases diagnosed based on histology or cytology and entered into the registry were retrieved and categorized by type/ organ sites affected according to International Classification of Diseases for Oncology.Results: There was a steady rise in frequency of cancer over the period where a total of 1990 cancer cases were recorded comprising of 1001 (50.3%) males and 989 (49.7%) females. Cancers of the cervix (22.9%), Breast (18.9%), Ovary (8.2%), non-melanoma skin cancer (6.3%), and Uterus (6.2%) were the most frequent female cancers. In males, cancer of the prostate (16.5%), bladder (10.2%), non-melanoma skin (9.9%), colorectum (9.3%) and connective tissue (6.3%) were most common. Burkitt's lymphoma (31.4%), other lymphoreticular cancers (23.8%) and retinoblastoma (20%) predominated in children. Conclusion:The KCR supports existing predictions of an increase in incidence of cancers in developing countries. There is need for establishment of comprehensive cancer control programmes in developing countries for the common cancers of the cervix, breast, prostate, bladder, skin and colorectum which are amenable to prevention, early detection and cure.

Backkground: The incidence of civilian gunshot injuries has been reported to be on the increase globally. This study was undertaken to determine the epidemiology of gunshot injuries in Kano, Northern Nigeria. Patients AND Methods:A retrospective analysis of patients with gunshot injuries seen at five major government hospitals in Kano metropolis over a four year period (1999-2002). Results: There were 224 cases, with males outnumbering females by a ratio of 27:1. Eighty-one point three percent of patients were aged between 20 and 44 years. The most commonly injured body regions were the lower limbs (31.6%), chest (15.6%) , upper limbs (9.4%) and head (9.0%). A fatal outcome was recorded in 12.5% of cases. Most injuries occurred among traders, students, farmers and security agents, and armed robbery attacks and civil conflicts were the aetiological factors in majority of cases. Conclusion: Gunshot injuries are a major cause of morbidity among adult men in Kano. Addressing the root causes of violence such as poverty, unemployment, and substance abuse will reduce the incidence of gunshot injuries in our society.

Background: Lymphadenopathy is a common clinical problem here in Kano, Northern Nigeria but there has been no formal study. We therefore undertook this review to evaluate the pattern in our locality. Method: This is a seven-year (1998)(1999)(2000)(2001)(2002)(2003)(2004) retrospective review of all histologically diagnosed lymph node biopsies received at Aminu Kano Teaching Hospital, Kano. Results: Cervical, axillary and inguinal nodes were the most frequently biopsied accounting for 46%, 23% and 13%, while tuberculosis, lymphomas and metastases were the most commonly diagnosed lesions comprising 30%, 24% and 19% respectively. In general, benign lesions were more common constituting 57% of nodal biopsies. Lymphadenopathy was observed to be most prevalent in the first three decades. Conclusion: Our findings were broadly similar to most other Nigerian studies and slightly at variance with other African countries but significantly different from the Western World. The limitations of lymph node histopathology in the absence of modern molecular diagnostic techniques are highlighted.Key words: Lymphadenopathy, tuberculosis, lymph node metastases, reactive hyperplasia Résumé Introduction: La lymphadenopathie est un probléme clinique courant ici à Kano, Nord du Nigeria, cependant il n'ya encore eu aucune étude formelle sur ce sujet. C'est pour cette raison que nous avons décidé d'entreprendre cette étude pour evaluer la distribution dans notre localité. Méthodes: Voici une etude retrospective faite en sept ans (1998)(1999)(2000)(2001)(2002)(2003)(2004)
