    ABSTRACT: Kenyan media reports indicate escalating levels of child maltreatment, but the characteristics of the offence are undefined. At the Gender and Violence recovery Center of the Nairobi Women's Hospital, we analysed 342 consecutive children for age, gender, perpetrator characteristics, time and scene of assault and the nature of injuries between February 2003 and April 2004. The children comprised 43.5% of all assault survivors. The mean age was 10.0 years and about 20% of the children were < or =5 years. Most (71.5%) of the child sexual abuse (CSA) was perpetrated by people known to the victim. Intra-family CSA (incest) was highest among the one to five year olds. The proportion of assaults committed against boys reduced with the age of the child. Older children were more likely to be assaulted later in the day and by multiple perpetrators. Most recorded injuries were perineal. The majority of children are assaulted by people they had trusted. The epidemiological correlates of maltreatment differ for younger and older children. More effort is needed to further characterize child violence and protect this vulnerable section of the population.

    ABSTRACT: CRC (CRC) rates are low but increasing in Africa. Data on detection, treatment, and outcome are scarce. The aim of this study was to evaluate the presentation, treatment, and outcome pattern of CRC and to compare the care processes for two time periods. The setting was Kenyatta National Hospital (KNH), a teaching and referral center. A total of 259 patients seen over two time periods (1993-1998 and 1999-2005) were analyzed for admission date, sex, subsite involvement, diagnostic process, treatment, follow-up, and outcome. The distribution of variables between the time periods were analyzed using Student's t-test and chi2 as appropriate. Survival trends were generated using Kaplan Meier method; p<0.05 was statistically significant. The average number of CRC diagnoses showed a 2.7-fold increase during the study periods. The mean age at presentation was 49.7 years. The mean duration of symptoms was 29.6 weeks; and the commonest subsite was the rectum (55.3%). The overall resection rate was 67.7%. For rectal tumors the abdominoperineal rate was 51.4%. Mortality was higher for poorly differentiated cancer, advanced disease, age>50 years, and emergency surgery. There was no change in the age, duration of symptoms, proportion of patients<40 years, or the colon/rectal ratios of the cancer site. The second time period saw more adjuncts for diagnosis, less in-hospital mortality, and better staging data. CRC peaks during the fifth decade of life in Kenyans. The disease is characterized by late presentation, rectal preponderance, and inadequate pathology data. Improved patient follow-up will unravel the true pattern of disease outcome.

    ABSTRACT: Knowledge of the variant vascular anatomy of the subhepatic region is important for hepatobiliary surgeons in limiting operative complications due to unexpected bleeding. The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepatic artery. Accessory arteries were observed to originate from proper hepatic artery (n = 5), left hepatic artery (n = 2), and right hepatic artery (n = 1). Most of the arteries approached the gallbladder in relation to the common hepatic duct (anterior 45.1%, posterior, 46.1%). The other vessels passed anterior to common bile duct (2.9%), posterior to common bile duct (3.9%), or were given off in Calot's triangle. Cystic arteries in this data set show wide variations in terms of relationship to the duct systems. In about one tenth of patients, an accessory cystic artery may need to be ligated or clipped during cholecystectomy.

    ABSTRACT: Background:The developing world continues to experience a disproportionate burden of injury. About one half of injury deaths are due to motor vehicle collisions. Road traffic fatalities per 10,000 vehicles are ten to 20 times higher in Africa compared to Europe.Patients and Methods:233 patients were consecutively analyzed. Injury acuity was determined by calculating Injury Severity Scores (ISS) for each patient. Information on the care and treatment outcome was obtained from patient interviews, case notes and discharge summaries. Data analysis was performed using the SPSS version 10.0 statistical software.Results:Injury accounted for 48.8% of all emergency hospitalizations into the surgical units. Injury due to traffic comprised a third (31%) of trauma admissions. Injuries to the limbs were predominant (54%). Acuity ranged from ISS 1 to 43. The mean ISS was 8.78. Major injury (ISS > 15) constituted 13% of all the admissions. Operating room resources were utilized in 52% of the patients (major operations were performed in 12% of this group). The overall complication rate was 12.0%. Although the overall mortality amounted to 6%, mortality was 35.6% amongst those with major injury. It was also higher with associated head injury, pedestrian injury and weekend injury.Conclusion:The overall trauma acuity was moderate injury. Mortality escalated to 35% for major injury. There is need to explore the factors contributing to this high mortality and a system of care that can optimize outcome.

    ABSTRACT: Background The rise in the use of motorcycles in Kenya in the last 10 years has been associated with increased injury rates. Between 2004 and 2009, motorcycle injuries increased at a rate of 29 % and, in some hospitals, motorcycle users have become the predominant road user category injured. Although most road traffic injuries occur in Nairobi, there has been no previous account of motorcycle injury and associated outcomes at its main hospital. Objective To describe the injury patterns and outcomes following motorcycle trauma at the Kenyatta National Hospital. Methods All motorcycle trauma admissions during one calendar year were analyzed. The data captured included demographics, injury patterns and outcomes, lengths of hospital stay, hospitalization cost, and early hospital mortality. Factors associated with outcomes were analyzed by univariate and multivariate means. The probability of survival was estimated using the Trauma and Injury Severity Score (TRISS) methodology for each patient. Results Two hundred and five patients were reviewed. Motorcycle trauma admissions formed 22.3 % of all road traffic injury admissions. Male riders predominated. The average age and modal age group was 30.78 and 21–30 years, respectively. Half of riders and 20 % of passengers used protective helmets. Injuries were mostly to the extremities (60.7 %) and head/neck (32.07 %), and the average Injury Severity Score (ISS) was 7.57 + 4.0 (median 9.0). At 2 weeks, 9.0 % of patients had died. The estimated probability of survival ranged from 0.86 to 0.97. Surgical interventions were needed for 51.7 % of patients. The mean length of stay in the hospital was 24.3 days, while the cost of treatment was 31,783 Kenya Shillings (Kshs). Injury severity (P < 0.001), admission to the intensive care unit (ICU) (P < 0.001), non-surgical treatment (P = 0.003), blood transfusion (P = 0.029), head injury (P < 0.001), and low Glasgow Coma Scale (GCS) score at admission were significantly associated with mortality. Conclusion Injuries to the lower limbs and the head predominate in motorcycle trauma. The high mortality rate, need for surgery in the majority of patients, and prolonged admission days call for motorcycle control and expedited care. Significant head injury mortality calls for efforts to embrace helmet laws for riders and passengers.
