Background and Objectives: Gunshot Injuries used to be rare in Nigeria until the civil war of 1967-1970. Unfortunately, it has become very rampant recently. The objective of this paper is to look at the epidemiology of armed robbery-related gunshot injuries as seen in the University of Maiduguri Teaching Hospital over a five-year period. Materials and Methods: Data on patients that presented with gunshot injuries within the study period (January 2002 to December 2006) were collected and analyzed retrospectively. Results: We studied 129 patients with gunshot injuries that were managed during the study period. This comprises of 117 males and 12 females (M:F=9.8:1). Eighty four (65.1%) were young males between 20 and 40 years. One hundred and fifteen (89.2%) of the 129 victims were shot by armed robbers, the remaining 14 (10.8%) were shot under other circumstances not related to armed robbery. Analysis of the time of attack revealed 72% of victims were attacked at night. Over 80% of victims were shot along the highway. The anatomical sites of gunshot entry wound show the extremities having the highest of 46.1%. Ninety one (79.1%) victims were treated operatively while 16 (13.9%) were treated nonoperatively. Conclusion: Armed robbery is the motive behind most gunshot injuries in Nigeria. Most of these attacks are preventable if the government would support and motivate the security apparatus responsible. There is also need for the government to support the victims by shouldering their treatment and subsequent rehabilitation.

BackgroundInvolvement of the kidneys in patients with sickle cell anaemia is a well recognised chronic complication. This study seeks to determine the prevalence of chronic kidney disease in patients with homozygous sickle cell disease (HbSS) and to identify risk factors associated with its development.MethodologyThe subjects consisted of adolescents and adults with HbSS recruited sequentially from the adult haematology outpatient clinic and Daycare ward of the unit. Clinical variables including age at diagnosis of SCA, the frequency of vaso-occlusive crisis and transfusion therapy, as well as laboratory data including haematological profile and renal function tests were obtained. The glomerular filtration rate was estimated (eGFR) using the ‘modification of diet in renal disease’ (MDRD) formula.ResultsTwo hundred and eighty-four HbSS patients were recruited. The prevalence of CKD amongst them was 38.9%. Further stratification of the patients based on eGFR showed that sixty-nine (26.8%) had hyperfiltration; 35 (13.6%) stage 1 CKD; 53 (20.6%) stage 2 CKD; 33 (12.8%) stage 3a CKD; 28 (10.9%) stage 3b CKD; 30 (11.7%) stage 4 CKD and 9 (3.5%) had end stage renal disease. There was significant association between eGFR and clinical parameters such as age (r −0.353, p=0.000), SBP (r −0.148, p= 0.021), DBP (r −0.213, p=0.001) and total number of blood received (r −0.276, p=0.000); and laboratory parameters such as PCV (r 0.371, p=0.000); urea ( r 0.527, p=000); creatinine (r 0.625, p=0.000) and uric acid ( r −0.419, p=0.000).ConclusionsThe present study has revealed a high prevalence of CKD amongst patients with SCA in our region. Clinical and laboratory predictors of CKD using eGFR were identified to include age, SBP, number of units of blood transfusion, PCV, urea, creatinine and uric acid levels.

Epigastric pain is a common complaint throughout Africa, mostly in the form of non-ulcer dyspepsia. It has recently been suggested that Helicobacter (= Campylobacter) pylori, a bacterium that colonizes the gastric mucosa and causes type B gastritis, may be the cause of this epigastric pain. This paper reports the endoscopic, histological and bacteriological findings in 57 patients presenting with epigastric pain to the University of Maiduguri teaching hospital during one year, together with a review of the African literature. Of 57 patients, 49 had non-ulcer dyspepsia, 7 peptic ulceration and 1 carcinoma of the stomach. 93% of the patients had histological gastritis, and of these 87% were colonized with H. pylori. The bacterium was cultured from 13 patients. This high prevalence of gastritis and H. pylori has been found throughout Africa. The figures support a causative role for H. pylori in histological gastritis. At present the evidence in support of a causative role in non-ulcer dyspepsia is not strong enough to be able to recommend the routine use of anti-H. pylori therapy in patients with epigastric pain.

Introduction: The loss of splenic function is associated with an increased risk of infection in sickle cell disease (SCD); however, spleen function is rarely documented among SCD patients in Africa, due partly to the non-availability of sophisticated techniques such as scintigraphy. Methods of assessing splenic function which may be achievable in resource-poor settings include counting red blood cells (RBC) containing Howell Jolly Bodies (HJB) and RBC containing silver-staining (argyrophilic) inclusions (AI) using a light microscope. We evaluated the presence of HJB - and AI - containing RBC as markers of splenic dysfunction among SCD patients in Nigeria. Methods: We prospectively enrolled children and adults with SCD in steady state attending outpatient clinics at a tertiary hospital in North-East Nigeria.  The percentages of HJB - and AI-containing red cells were estimated from peripheral blood smears and compared to normal controls. Results: There were 182 SCD patients and 102 healthy controls. Both AI- and HJB-containing red cells could be easily identified in the participants blood smears. SCD patients had a significantly higher proportion of red cells containing HJB (1.5%; IQR 0.7% -  3.1%) compared to controls (0.3%; IQR 0.1% - 0.5%) (P = 0.0001). The AI red cell counts were also higher among the SCD patients (47.4%; IQR 34.5% - 66.0%) than the control group (7.1%; IQR 5.1% - 8.7%)  (P = 0.0001). The intra-observer reliability for assessment of HJB- (R = 0.92;  R2 = 0.86) and AI- containing red cells (R = 0.90; R2 = 0.82) was high. The estimated intra-observer agreement was better with the HJB count method (95% limits of agreement, -4.5 to 4.3; P = 0.579). There were 182 SCD patients and 102 healthy controls. SCD patients had a significantly higher proportion of red cells containing HJB compared to controls (median 1.5% vs 0.3% respectively; P = 0.0001). The AI red cell counts were also higher among the SCD patients than the controls (median 47.5% vs 7.1% respectively; P = 0.0001). The intra-observer reliability for assessment of HJB- (R = 0.92; R2 = 0.86) and AI- containing red cells (R = 0.90; R2 = 0.82) was high. The estimated intra-observer agreement was better with the HJB count method (95% limits of agreement, -4.5 to 4.3; P = 0.579). Conclusion: We have demonstrated the utility of light microscopy in the assessment of red cells containing - HJB and AI inclusions as indices of splenic dysfunction in Nigerian SCD patients. These methods can be easily applied in the routine evaluation and care of patients with SCD to identify those at high risk of infection and initiate appropriate preventive measures.
