Epidemiological data on neonatal bloodstream infections (BSI) in sub-Saharan Africa are extremely limited. A comparative analysis of laboratory-confirmed neonatal BSI episodes was conducted retrospectively in two large neonatal units in Botswana and South Africa (January 1 to December 31, 2017). Routine laboratory and ward register data were used to determine BSI rates, the pathogen spectrum, and BSI outcomes. In 2017, the Princess Marina Hospital (PMH) and Tygerberg Hospital (TBH) neonatal units admitted 1187 and 2826 neonates, respectively. The BSI incidence rate was 12.1/1000 patient-days (95% confidence interval (CI) 10.2-14.3) at PMH and 3.5/1000 patient-days (95% CI 2.9-4.1) at TBH (p < 0.0001). Most BSI episodes were hospital-acquired (260/284; 91.6%). The blood culture contamination rate was substantially higher at PMH than TBH (152/1116 (13.6%) vs 122/2559 (4.8%); p < 0.001). The crude mortality rate in neonates with BSI was 21.2% (53/250) and significantly higher at TBH than PMH (38/128 (29.7%) vs 15/122 (12.3%), p = 0.001). Factors independently associated with death were birth weight <1500 g (adjusted odds ratio (aOR) 2.8, 95% CI 1.3-6.4; p = 0.02) and male sex (aOR 2.1, 95% CI 1.1-3.7; p = 0.01). Klebsiella pneumoniae was the dominant BSI pathogen in both units, accounting for two-thirds of BSI, and was associated with a large infection outbreak at PMH. Antibiotic resistance rates were substantial in both neonatal units, particularly for K. pneumoniae (98/122 (80.3%), extended-spectrum beta-lactamase (ESBL)-producers) and Staphylococcus aureus (22/33 (66.7%), methicillin-resistant). BSI rates and associated mortality were substantial in these two neonatal units in sub-Saharan Africa. ESBL-producing K. pneumoniae remains a leading BSI and outbreak pathogen.

Globally, mental health problems have been reported to be more common in youth living with HIV (YLWH) than in the general population, but routine mental health screening is rarely done in high-volu...

We conducted a survey of doctors working in the cardiac catheterisation laboratories in Africa on their knowledge, attitude and practice with respect to radiation protection. Of seventy-two respondents contacted, 61 (84.7%) completed the questionnaire. Twenty-eight, (45.9%) were younger than 45 years. Thirty-seven, (60.6%) had less than 10 years of experience in the laboratory. Only 28 (45.9%) had undertaken radiation protection training. Fifty-eight, (95.1%) consistently used lead aprons. Forty-seven, (77%) reported consistently using thyroid shields. Ten (16.4%) consistently used radiation protection eyeglasses, whilst 36 (59%) never used them. Thermoluminescent Dosimeter badges were consistently used in 23 (37.7%). Forty-two, (68.9%) reported having ceiling mounted lead/acrylic shields. Level of radiation exposure in the most recent one year was ≤2 mSv in 14, between 2 and 20 mSv in 8 and between 20 and 30 mSv in 2, whilst 33 did not know their dose readings. The use of basic radiation protection tools as well as the knowledge and measurement of radiation exposure among interventional cardiologists working in Africa is low. The unavailability of some of the protective tools and a knowledge gap in terms of radiation protection and monitoring of self-exposure were some of the reasons for suboptimal self-protection against ionising radiation among our respondents. We suggest that initiatives be taken by all stakeholders to train this group of medical professionals in basic radiation protection to avoid unnecessary exposure to themselves, co-workers and patients.

INTRODUCTION: Retinoblastoma is a primary malignant intraocular neoplasm that arise from immature retinoblasts with in developing retina. The commonest presenting sign in developing country is proptosis which is the late presenting sign. We report presenting signs of retinoblastoma in Ethiopian children seen at a tertiary level teaching hospitals in Ethiopia. METHODS: prospective case series study wasdone on children who presented with retinoblastoma between May 1, 2005 and September 1, 2006. This study was done as part of requirement for partial fulfilment of certificate of speciality study in ophthalmology during the year 2005 to 2006. SPSS 11 statistical package was used to analyse the data. RESULTS: among 41 patients seen during the study period, 24 (58.5%) were males and 17(41%) were females. Unilateral retinoblastoma wasfound in 32 (78%) patients and bilateral cases were found in 9(22%). Mean age of onset for right eye was 27.5 months and left eye 33.7 months.The mean ages of presentation at time of diagnosis for right and left eye were 34.4 and 40.2 months, respectively .In bilateral retinoblastoma mean age of presentation was 33.3 months.The commonest presenting sign was proptosis 22(53.7%) followed by leucocorea nine (22%),ocular inflammation four (9.0 %), strabismus three (7.3%), glaucoma one (2.4%), loss of vision one (2.4%)and hyphemaone (2.4%). CONCLUSION: the commonest presenting signs of retinoblastoma in our set up were Proptosis followed by leucocorea. This is due to late presentation of patient and late referral by medical professionals. Health education to the public and health professionals will help early detection of retinoblastoma.

Introduction: Microalbuminuria is considered the earliest sign of diabetic nephropathy among patients with type 1 diabetes mellitus (T1DM). The prevalence of microalbuminuria among African children with T1DM is reported to be high, yet its prevalence and population-specific risk factors in Botswana are not known. Aim: This study aimed to determine the prevalence of microalbuminuria among children and young adults with T1DM in Botswana and identify factors associated with microalbuminuria in this population. Methods: A retrospective cross-sectional study was conducted on 127 T1DM patients aged < 24 years followed at a pediatric endocrinology clinic in Botswana from 2010 to 2017. Clinical, laboratory, and demographic data were collected using chart review and patient surveys. Descriptive statistics were reported as mean and standard deviation for continuous variables, and frequency and percentage for categorical variables. Prevalence of microalbuminuria was calculated as a simple proportion. Group comparison was done using two-sample independent t-test, X²-test, or Fisher’s exact test and logistic regression to assess for associations. Level of significance was set at p< 0.05. Results: There were a total of 71 (55.9%) females. The mean age was 18.7 (± 5) years and mean duration of T1DM was 6.6 (± 4.6) years. Most study participants were of African descent. The prevalence of microalbuminuria was 28.3%. Group comparison revealed gender (p= 0.040), duration of diabetes (p= 0.002), systolic blood pressure (p=0.003), baseline glycated hemoglobin (HbA1c) (p=0.009) and Tanner’s stage (p=008) to be significantly associated with microalbuminuria. On binary logistic regression, only gender (p=0.039) and baseline HbA1c (p=0.039) were independently associated with the presences of microalbuminuria. Conclusion: This study identified a high prevalence of microalbuminuria among children and young adults with T1DM in Botswana and reaffirms the importance of early detection, glycemic control, and regular screening to prevent diabetic nephropathy.

Sepsis is the leading postnatal cause of neonatal mortality worldwide. Globally Klebsiella pneumoniae is the leading cause of sepsis in hospitalized neonates. This study reports the development and evaluation of an ELISA for anti-Klebsiella IgG using dried blood spot (DBS) samples and evaluates the association of anti-Klebsiella IgG (anti-Kleb IgG) antibodies in maternal and neonatal samples with the risk of neonatal sepsis. Neonates and their mothers were enrolled at 0–96 hours of life in the neonatal unit of a tertiary referral hospital in Gaborone, Botswana and followed until death or discharge to assess for episodes of blood culture-confirmed neonatal sepsis. Neonates with sepsis had significantly lower levels of Kleb-IgG compared to neonates who did not develop sepsis (Mann-Whitney U, p = 0.012). Similarly, samples from mothers of neonates who developed sepsis tended to have less Kleb-IgG compared to mothers of controls. The inverse correlation between Kleb-IgG levels and all-cause bacteremia suggests that maternal Kleb-IgG may be protective through cross-reactivity with common bacterial epitopes. These data support the continued use of immunoglobulin assays using DBS samples to explore the role of passive immunity on neonatal sepsis risk and reaffirm the critical need for research supporting the development of maternal vaccines for neonatal sepsis.
