RESUMO
Prior research suggests that fluvoxamine, a selective serotonin reuptake inhibitor (SSRI) used for the treatment of obsessive-compulsive disorder and major depressive disorder, could be repurposed against COVID-19. We undertook a prospective interventional open-label cohort study to evaluate the efficacy and tolerability of fluvoxamine among inpatients with laboratory-confirmed COVID-19 in Uganda. The main outcome was all-cause mortality. Secondary outcomes were hospital discharge and complete symptom resolution. We included 316 patients, of whom 94 received fluvoxamine in addition to standard care [median age, 60 years (IQR = 37.0); women, 52.2%]. Fluvoxamine use was significantly associated with reduced mortality [AHR = 0.32; 95% CI = 0.19-0.53; p < 0.001, NNT = 4.46] and with increased complete symptom resolution [AOR = 2.56; 95% CI = 1.53-5.51; p < 0.001, NNT = 4.44]. Sensitivity analyses yielded similar results. These effects did not significantly differ by clinical characteristic, including vaccination status. Among the 161 survivors, fluvoxamine was not significantly associated with time to hospital discharge [AHR 0.81, 95% CI (0.54-1.23), p = 0.32]. There was a trend toward greater side effects with fluvoxamine (7.45% versus 3.15%; SMD = 0.21; χ2 = 3.46, p = 0.06), most of which were light or mild in severity and none of which were serious. One hundred mg of fluvoxamine prescribed twice daily for 10 days was well tolerated and significantly associated with reduced mortality and with increased complete symptom resolution, without a significant increase in time to hospital discharge, among inpatients with COVID-19. Large-scale randomized trials are urgently needed to confirm these findings, especially for low- and middle-income countries, where access to vaccines and approved treatments against COVID-19 is limited.
RESUMO
BACKGROUND: Pre-eclampsia is the second leading cause of maternal death in Uganda. However, mothers report to the hospitals late due to health care challenges. Therefore, we developed and validated the prediction models for prenatal screening for pre-eclampsia. METHODS: This was a prospective cohort study at St. Mary's hospital lacor in Gulu city. We included 1,004 pregnant mothers screened at 16-24 weeks (using maternal history, physical examination, uterine artery Doppler indices, and blood tests), followed up, and delivered. We built models in RStudio. Because the incidence of pre-eclampsia was low (4.3%), we generated synthetic balanced data using the ROSE (Random Over and under Sampling Examples) package in RStudio by over-sampling pre-eclampsia and under-sampling non-preeclampsia. As a result, we got 383 (48.8%) and 399 (51.2%) for pre-eclampsia and non-preeclampsia, respectively. Finally, we evaluated the actual model performance against the ROSE-derived synthetic dataset using K-fold cross-validation in RStudio. RESULTS: Maternal history of pre-eclampsia (adjusted odds ratio (aOR) = 32.75, 95% confidence intervals (CI) 6.59-182.05, p = 0.000), serum alkaline phosphatase(ALP) < 98 IU/L (aOR = 7.14, 95% CI 1.76-24.45, p = 0.003), diastolic hypertension ≥ 90 mmHg (aOR = 4.90, 95% CI 1.15-18.01, p = 0.022), bilateral end diastolic notch (aOR = 4.54, 95% CI 1.65-12.20, p = 0.003) and body mass index of ≥ 26.56 kg/m2 (aOR = 3.86, 95% CI 1.25-14.15, p = 0.027) were independent risk factors for pre-eclampsia. Maternal age ≥ 35 years (aOR = 3.88, 95% CI 0.94-15.44, p = 0.056), nulliparity (aOR = 4.25, 95% CI 1.08-20.18, p = 0.051) and white blood cell count ≥ 11,000 (aOR = 8.43, 95% CI 0.92-70.62, p = 0.050) may be risk factors for pre-eclampsia, and lymphocyte count of 800 - 4000 cells/microliter (aOR = 0.29, 95% CI 0.08-1.22, p = 0.074) may be protective against pre-eclampsia. A combination of all the above variables predicted pre-eclampsia with 77.0% accuracy, 80.4% sensitivity, 73.6% specificity, and 84.9% area under the curve (AUC). CONCLUSION: The predictors of pre-eclampsia were maternal age ≥ 35 years, nulliparity, maternal history of pre-eclampsia, body mass index, diastolic pressure, white blood cell count, lymphocyte count, serum ALP and end-diastolic notch of the uterine arteries. This prediction model can predict pre-eclampsia in prenatal clinics with 77% accuracy.

BACKGROUND: Women of Afro-Caribbean and Asian origin are more at risk of stillbirths. However, there are limited tools built for risk-prediction models for stillbirth within sub-Saharan Africa. Therefore, we examined the predictors for stillbirth in low resource setting in Northern Uganda. METHODS: Prospective cohort study at St. Mary's hospital Lacor in Northern Uganda. Using Yamane's 1967 formula for calculating sample size for cohort studies using finite population size, the required sample size was 379 mothers. We doubled the number (to > 758) to cater for loss to follow up, miscarriages, and clients opting out of the study during the follow-up period. Recruited 1,285 pregnant mothers at 16-24 weeks, excluded those with lethal congenital anomalies diagnosed on ultrasound. Their history, physical findings, blood tests and uterine artery Doppler indices were taken, and the mothers were encouraged to continue with routine prenatal care until the time for delivery. While in the delivery ward, they were followed up in labour until delivery by the research team. The primary outcome was stillbirth 24 + weeks with no signs of life. Built models in RStudio. Since the data was imbalanced with low stillbirth rate, used ROSE package to over-sample stillbirths and under-sample live-births to balance the data. We cross-validated the models with the ROSE-derived data using K (10)-fold cross-validation and obtained the area under curve (AUC) with accuracy, sensitivity and specificity. RESULTS: The incidence of stillbirth was 2.5%. Predictors of stillbirth were history of abortion (aOR = 3.07, 95% CI 1.11-8.05, p = 0.0243), bilateral end-diastolic notch (aOR = 3.51, 95% CI 1.13-9.92, p = 0.0209), personal history of preeclampsia (aOR = 5.18, 95% CI 0.60-30.66, p = 0.0916), and haemoglobin 9.5 - 12.1 g/dL (aOR = 0.33, 95% CI 0.11-0.93, p = 0.0375). The models' AUC was 75.0% with 68.1% accuracy, 69.1% sensitivity and 67.1% specificity. CONCLUSION: Risk factors for stillbirth include history of abortion and bilateral end-diastolic notch, while haemoglobin of 9.5-12.1 g/dL is protective.

Chronic pulmonary aspergillosis (CPA) complicates treated pulmonary tuberculosis (TB), with high 5-year mortality. We measured CPA prevalence in this group.398 Ugandans with treated pulmonary TB underwent clinical assessment, chest radiography and Aspergillus-specific IgG measurement. 285 were resurveyed 2â years later, including computed tomography of the thorax in 73 with suspected CPA. CPA was diagnosed in patients without active TB who had raised Aspergillus-specific IgG, radiological features of CPA and chronic cough or haemoptysis.Author-defined CPA was present in 14 (4.9%, 95% CI 2.8-7.9%) resurvey patients. CPA was significantly more common in those with chest radiography cavitation (26% versus 0.8%; p<0.001), but possibly less frequent in HIV co-infected patients (3% versus 6.7%; p=0.177) The annual rate of new CPA development between surveys was 6.5% in those with chest radiography cavitation and 0.2% in those without (p<0.001). Absence of cavitation and pleural thickening on chest radiography had 100% negative predictive value for CPA. The combination of raised Aspergillus-specific IgG, chronic cough or haemoptysis and chest radiography cavitation had 85.7% sensitivity and 99.6% specificity for CPA diagnosis.CPA commonly complicates treated pulmonary TB with residual chest radiography cavitation. Chest radiography alone can exclude CPA. Addition of serology can diagnose CPA with reasonable accuracy.

ACS (ACS) is a serious complication of sickle cell anaemia (SCA). We set out to describe the burden, presentation and organisms associated with ACS amongst children with SCA attending Mulago Hospital, Kampala, Uganda. In a cross-sectional study, 256 children with SCA and fever attending Mulago Hospital were recruited. Chest X-rays, blood cultures, complete blood count and sputum induction were performed. Sputum samples were investigated by Ziehl-Nielsen staining, culture and DNA polymerase chain reaction (PCR) for Chlamydia pneumoniae. Of the 256 children, 22·7% had ACS. Clinical and laboratory findings were not significantly different between children with ACS and those without, besides cough and abnormal signs on auscultation. Among the 83 sputum cultures Streptococcus pneumoniae (12%) and Moraxella spp (8%), were the commonest. Of the 59 sputa examined with DNA PCR, 59·3% were positive for Chlamydia pneumoniae. Mycobacterium tuberculosis was isolated in 6/83 sputa. These results show that one in 5 SCA febrile children had ACS. There were no clinical and laboratory characteristics of ACS, but cough and abnormalities on auscultation were associated with ACS. The high prevalence of Chlamydia pneumoniae in children with ACS in this setting warrants the addition of macrolides to treatment, and M. tuberculosis should be differential in sub-Saharan children with ACS.

BACKGROUND: Ultrasonography is essential in the prenatal diagnosis and care for the pregnant mothers. However, the measurements obtained often contain a small percentage of unavoidable error that may have serious clinical implications if substantial. We therefore evaluated the level of intra and inter-observer error in measuring mean sac diameter (MSD) and crown-rump length (CRL) in women between 6 and 10 weeks' gestation at Mulago hospital. METHODS: This was a cross-sectional study conducted from January to March 2016. We enrolled 56 women with an intrauterine single viable embryo. The women were scanned using a transvaginal (TVS) technique by two observers who were blinded of each other's measurements. Each observer measured the CRL twice and the MSD once for each woman. Intra-class correlation coefficients (ICCs), 95% limits of agreement (LOA) and technical error of measurement (TEM) were used for analysis. RESULTS: Intra-observer ICCs for CRL measurements were 0.995 and 0.993 while inter-observer ICCs were 0.988 for CRL and 0.955 for MSD measurements. Intra-observer 95% LOA for CRL were ± 2.04 mm and ± 1.66 mm. Inter-observer LOA were ± 2.35 mm for CRL and ± 4.87 mm for MSD. The intra-observer relative TEM for CRL were 4.62% and 3.70% whereas inter-observer relative TEM were 5.88% and 5.93% for CRL and MSD respectively. CONCLUSIONS: Intra- and inter-observer error of CRL and MSD measurements among pregnant women at Mulago hospital were acceptable. This implies that at Mulago hospital, the error in pregnancy dating is within acceptable margins of ±3 days in first trimester, and the CRL and MSD cut offs of ≥7 mm and ≥ 25 mm respectively are fit for diagnosis of miscarriage on TVS. These findings should be extrapolated to the whole country with caution. Sonographers can achieve acceptable and comparable diagnostic accuracy levels of MSD and CLR measurements with proper training and adherence to practice guidelines.

AIM: There is limited literature on brain imaging studies of children with cerebral palsy (CP) in low and middle income countries. We investigated neuroimaging patterns of children with CP attending a tertiary referral centre in Uganda to determine how they differed from studies reported from high income countries and their relationship with prenatal and postnatal factors. METHODS: Precontrast and postcontrast computed tomography (CT) scans of 78 CP children aged 2-12 years were conducted using a Philips MX 16-slice CT scanner. Two radiologists, blinded to the patient's clinical status, independently reviewed the scans. RESULTS: Abnormal CT scans were detected in 69% of the children sampled, with very few having primary white matter injuries (4%). Primary grey matter injuries (PGMI) (44%) and normal scans (31%) were most frequent. Children with a history of hospital admission following birth were three times more likely to have PGMI (odds ratio [OR] 2.8; 95% CI 1.1-7.1), suggesting a perinatal period with medical complications. CONCLUSION: Brain imaging patterns in this group of CP children differed markedly from imaging studies reported from high income countries, suggesting a perinatal aetiology in full-term infants and reduced survival in preterm infants.

INTRODUCTION: Evidence that supports the use of COVID-19 convalescent plasma (CCP) for treatment of COVID-19 is increasingly emerging. However, very few African countries have undertaken the collection and processing of CCP. The aim of this study was to assess the feasibility of collecting and processing of CCP, in preparation for a randomized clinical trial of CCP for treatment of COVID-19 in Uganda. METHODS: In a cross-sectional study, persons with documented evidence of recovery from COVID-19 in Uganda were contacted and screened for blood donation via telephone calls. Those found eligible were asked to come to the blood donation centre for further screening and consent. Whole blood collection was undertaken from which plasma was processed. Plasma was tested for transfusion transmissible infections (TTIs) and anti-SARS CoV-2 antibody titers. SARS-CoV-2 testing was also done on nasopharyngeal swabs from the donors. RESULTS: 192 participants were contacted of whom 179 (93.2%) were eligible to donate. Of the 179 eligible, 23 (12.8%) were not willing to donate and reasons given included: having no time 7(30.4%), fear of being retained at the COVID-19 treatment center 10 (43.5%), fear of stigma in the community 1 (4.3%), phobia for donating blood 1 (4.3%), religious issues 1 (4.4%), lack of interest 2 (8.7%) and transport challenges 1 (4.3%). The median age was 30 years and females accounted for 3.7% of the donors. A total of 30 (18.5%) donors tested positive for different TTIs. Antibody titer testing demonstrated titers of more than 1:320 for all the 72 samples tested. Age greater than 46 years and female gender were associated with higher titers though not statistically significant. CONCLUSION: CCP collection and processing is possible in Uganda. However, concerns about stigma and lack of time, interest or transport need to be addressed in order to maximize donations.

INTRODUCTION: the third Sustainable Development Goal (SDG) relates to Universal Health Coverage (UHC) and provision of quality essential health services. The Government of Uganda has operationalized this through the National Health Policy which stresses the importance of availability of functioning medical equipment in health facilities. There have been efforts by the Ministry of Health and Atomic Energy Council in Uganda to compile an inventory of imaging equipment in the country, however, this information has not been widely published. The purpose of this study was to conduct an audit of registered radiology equipment in Uganda and establish their functional status. METHODS: a cross-sectional descriptive study that involved a desktop review of the equipment registry at the Uganda Atomic Energy Council was conducted. Data was collected on a number of variables including type of equipment, location, functional status, modality and density per million people. RESULTS: the audit revealed 625 pieces of equipment spread over 354 health facilities. The majority (397) were plain X-ray machines followed by dental X-ray machines at 120. There were only 3 Radiotherapy machines. Most were recorded as being functional with only 0.1% of the equipment non-functional. Most of the equipment was in the central region which has the third highest population density. The majority of the equipment belonged to private health facilities. CONCLUSION: Uganda lags behind the WHO recommended ratio of equipment versus the population (20 per million population). Most of the equipment is the plain X-ray machine with a few more advanced technologies in both public and private health facilities.

RATIONALE: Detailed data on the characteristics and outcomes of patients with COVID-19 in sub-Saharan Africa are limited. OBJECTIVE: We determined the clinical characteristics and treatment outcomes of patients diagnosed with COVID-19 in Uganda. MEASUREMENTS: As of the 16 May 2020, a total of 203 cases had been confirmed. We report on the first 56 patients; 29 received hydroxychloroquine (HCQ) and 27 did not. Endpoints included admission to intensive care, mechanical ventilation or death during hospitalisation. MAIN RESULTS: The median age was 34.2 years; 67.9% were male; and 14.6% were <18 years. Up 57.1% of the patients were asymptomatic. The most common symptoms were fever (21.4%), cough (19.6%), rhinorrhea (16.1%), headache (12.5%), muscle ache (7.1%) and fatigue (7.1%). Rates of comorbidities were 10.7% (pre-existing hypertension), 10.7% (diabetes) and 7.1% (HIV), Body Mass Index (BMI) of ≥30 36.6%. 37.0% had a blood pressure (BP) of >130/90 mm Hg, and 27.8% had BP of >140/90 mm Hg. Laboratory derangements were leucopenia (10.6%), lymphopenia (11.1%) and thrombocytopenia (26.3%). Abnormal chest X-ray was observed in 14.3%. No patients reached the primary endpoint. Time to clinical recovery was shorter among patients who received HCQ, but this difference did not reach statistical significance. CONCLUSION: Most of the patients with COVID-19 presented with mild disease and exhibited a clinical trajectory not similar to other countries. Outcomes did not differ by HCQ treatment status in line with other concluded studies on the benefit of using HCQ in the treatment of COVID-19.

Carotid artery disease which includes carotid artery stenosis, plaques, clots and increased intima media thickness, have been reported by many studies to be associated with dementia. Dementia is an end stage of usually asymptomatic cognitive impairment. Risk factors of carotid artery disease include; age, atherosclerosis, arteriosclerosis, shorter years in school, history of hypertension, diabetes mellitus, stroke and depression. This study set out to determine the prevalence of abnormal carotid ultrasound findings and their association with cognitive function among the adults ≥60â¯years in Wakiso district, Uganda in 2018. A total of 210 participants were included. Carotid artery stenosis, presence of plaque, stenosis and intima-media thickness were assessed by ultrasound. Cognitive status was assessed using a Mini Mental State Exam (MMSE) test. The prevalence of plaque was 21.4%. Variables which included; presence of plaque, age, education, gender, marital status, whether participant stayed alone or with someone else, care for self, occupation status, division of staying and history of smoking. The presence of plaque was associated with an abnormal cognitive function at both univariate and multivariate analysis with respective ORâ¯=â¯3.8 (95% CIâ¯=â¯1.90-7.54, p-valueâ¯=â¯0.0001) and ORâ¯=â¯3.4 (95% CIâ¯=â¯1.38-8.15, p-valueâ¯=â¯0.007). The cognitive function distribution was 43.8%, 19%, 34.3% and 2.9% within the normal, mild, moderate, and severe cognitive function status respectively. This study showed that prevalence of carotid artery plaque was high in this elderly population in Wakiso district Uganda. Also, carotid artery plaque was associated with abnormal cognitive function.

INTRODUCTION: The Faculty of Medicine, Makerere University, is the oldest health professionals' training institution in East Africa. It has been training health professionals since 1924. In 2001, a bachelors degree in radiography commenced. After a curriculum review, the university's longstanding traditional curriculum was converted to a problem based learning curriculum with a focus on Community Based Education and Service (COBES). As a component of COBES, radiography, medical, nursing, dentistry and pharmacy students are sent to community health facilities where they are expected to participate in community services and other primary healthcare activities. This study was designed to obtain radiography teachers' and students' opinions of the significance and relevance of this community based training to radiography training. METHODS: Cross-sectional descriptive study. RESULTS: Both students and teachers (91.4%) affirmed the community training to be significant and relevant to radiography training. In total, 71.4% of the students had participated in X-ray services and 39.2% in ultrasound services during COBES; and 68.6% of the students reported the need to be better prepared for the COBES training. CONCLUSION: Both students and teachers confirmed COBES to be relevant to Ugandan radiography training.

AIM: The aim of this study was to investigate epidemiological features of maxillofacial fractures within trauma patients who had head and neck computed tomography (CT) scan at the Mulago National referral hospital. METHODS: CT scan records of trauma patients who had head scans at the Department of Radiology over 1-year period were accessed. Data collected included sociodemographic factors, type and etiology of injury, and concomitant maxillofacial injuries. RESULTS: A total of 1330 trauma patients underwent head and neck CT scan in the 1-year study period. Out of these, 130 were excluded due to incomplete or unclear records and no evidence of injury. Of the remaining 1200, 32% (387) had maxillofacial fractures. The median age of the patients with maxillofacial fractures was 28 (range = 18-80) years and 18-27 age group was most common at 47.5%. Road traffic accidents constituted 49.1% of fractures. The single most affected isolated bone was the frontal bone (23%). The number of maxillofacial bones fractured was predicted by age group (df = 3 F = 5.358, P = 0.001), association with other fractures (df = 1 F = 5.317, P = 0.03). CONCLUSIONS: Good matched case-control prospective studies are needed to enable us tease out the finer difference in the circumstances and pattern of injury if we are to design appropriate preventive measures.
RESUMO
INTRODUCTION: Hysterosalpingography (HSG) is still a commonly used investigation in the evaluation of the female genital tract and the main indication for HSG is infertility. OBJECTIVE: The purpose of this study was to find the pathology detected at HSG in patients with infertility in our setting. MATERIALS AND METHODS: A retrospective review of 289 consecutive patients who underwent hysterosalpingography using ionic water-soluble contrast media was done at 2 private x-ray units in Kampala. Clinical notes and radiological findings were analysed for demographic data, uterine status, tubal and pelvic pathology. RESULTS: The commonest age group seen was 26-30 yrs. Most were of low parity. Secondary infertility was commoner than primary infertility. Abnormal findings at hysterosalpingography were found in 83.4%. The commonest finding was tubal blockage. CONCLUSION: The commonest pathology found on HSG in women presenting with infertility in Kampala is tubal blockage possibly secondary to chronic pelvic inflammation. The fact that secondary infertility is common points to pelvic infection complicating mismanaged pregnancies, septic abortions or sexually transmitted infections. A study to establish associated factors is recommended.

OBJECTIVES: Uganda, has limited health resources and improving performance of personnel involved in imaging is necessary for efficiency. The objectives of the study were to develop and pilot imaging user performance indices, document non-tangible aspects of performance, and propose ways of improving performance. MATERIALS AND METHODS: This was a cross-sectional survey employing triangulation methodology, conducted in Mulago National Referral Hospital over a period of 3 years from 2005 to 2008. The qualitative study used in-depth interviews, focus group discussions, and self-administered questionnaires, to explore clinicians' and radiologists' performancerelated views. RESULTS: THE STUDY CAME UP WITH FOLLOWING INDICES: appropriate service utilization (ASU), appropriateness of clinician's nonimaging decisions (ANID), and clinical utilization of imaging results (CUI). The ASU, ANID, and CUI were: 94%, 80%, and 97%, respectively. The clinician's requisitioning validity was high (positive likelihood ratio of 10.6) contrasting with a poor validity for detecting those patients not needing imaging (negative likelihood ratio of 0.16). Some requisitions were inappropriate and some requisition and reports lacked detail, clarity, and precision. CONCLUSION: Clinicians perform well at imaging requisition-decisions but there are issues in imaging requisitioning and reporting that need to be addressed to improve performance.
RESUMO
OBJECTIVES: The first objective of the study was to develop an index termed as the 'Imaging Coverage' (IC), for measuring the performance of the imaging health systems. This index together with the Hospital-Based Utilization (HBU) would then be calculated for five Ugandan hospitals. Second, was to relate the financial resources and existing health policy to the performance of the imaging systems. MATERIALS AND METHODS: This was a cross-sectional survey employing the triangulation methodology, conducted in Mulago National Referral Hospital. The qualitative study used cluster sampling, in-depth interviews, focus group discussions, and self-administered questionnaires to explore the non-measurable aspects of the imaging systems' performances. RESULTS: The IC developed and tested as an index for the imaging system's performance was 36%. General X-rays had the best IC followed by ultrasound. The Hospital-Based Utilization for the five selected hospitals was 186 per thousand and was the highest for general radiography followed by ultrasound. CONCLUSION: The IC for the five selected hospitals was 36% and the HBU was 186 per thousand, reflecting low performance levels, largely attributable to inadequate funding. There were shortfalls in imaging requisitions and inefficiencies in the imaging systems, financing, and health policy. Although the proportion of inappropriate imaging was small, reducing this inappropriateness even further would lead to a significant total saving, which could be channeled into investigating more patients. Financial resources stood out as the major limitation in attaining the desired performance and there is a need to increase budget funding so as to improve the performance of the imaging health systems.
RESUMO
INTRODUCTION: Uganda has limited health resources. It is important to measure the need for imaging in order to set policy and plan for imaging services. OBJECTIVES: The first specific objective was to develop and apply four imaging needs indices on a case study basis, in five selected Ugandan hospitals. The indices were: Imaging Load (IL), Imaging Burden (IB), Type Specific Imaging Burden (TSIB), and Disease Specific Imaging Burden (DSIB). The second objective was to explore the perceptions of the patient, referring clinician, and radiologist regarding the values, meaning, and objective of imaging in patient care. MATERIALS AND METHODS: This was a cross-sectional survey employing triangulation methodology, conducted in 5 Ugandan hospitals over a period of 3 years during 2005 - 2008. The subjects were divided into four clusters: Obstetrics and gynecology (obs/gynae), surgery, internal medicine, and pediatrics. For the quantitative component of the study, data from case notes was used to calculate the indices. The qualitative component explored the non-measurable aspects of imaging needs from the clinician's, radiologist's, and patient's perspective. RESULTS: A total of 1961 patient case notes were studied. The IB was 460 per 1000 hospital patients per year. The highest TSIB was for ultrasound at 232 per 1000 hospital patients per year, followed by 191 patients for general X-ray. The majority of the patients interviewed had special desires, expectations, and misconceptions. CONCLUSIONS: There is a high IB of 460 per thousand patient populations per year, mainly due to ultrasound. The majority of the patients have perceptions, misconceptions, beliefs, and values which influence the need for imaging. There is a need to address the medical and non-tangible imaging needs of the patient and to counteract imaging-related misconceptions and over-expectations. Public awareness of the value, capabilities, limitations, and adverse effects of various imaging modalities need to be addressed to ensure that the patients make informed imaging choices and readily avail themselves of interventions in situations when imaging is crucial, for example in suspected high-risk pregnancy.
RESUMO
BACKGROUND: Maternal mortality is related to obstetric complications in pregnancy some of which could be revealed by obstetric sonography. Obstetric sonography has become part of routine antenatal care in both urban and rural settings. The objective of the study was to assess the utilization of obstetric sonography in a rural hospital of Uganda, including the frequency and appropriateness of its usage as well as determine whether there was any relation between number of obstetric scans, patient management and obstetric outcomes. METHODS: It was a retrospective study in which review of all obstetric charts and obstetric scan requisition forms for all deliveries in Ndejje Health Centre (Uganda) was done. RESULTS: During the study period, there were 105 singleton deliveries, and these mothers underwent a total of 232 obstetric scans. More than half (53.4%) of the scans were classified as inappropriate. There were no significant differences in the number of scans between low- and high-risk pregnancies or between uncomplicated deliveries and those in which induction or instrumental or operative delivery occurred, nor was there any relation between number of scans and obstetric outcome. CONCLUSION: Obstetric sonography has become popular in rural health settings as part of antenatal care. However, it was over-used in the health centre. This overuse was not associated with any identifiable effect on obstetric outcome. Therefore, more appropriate use of obstetric sonography, in accordance with evidence-based guidelines, is recommended.

Camurati-Engelmann's disease is a rare condition worldwide. No cases have been documented in Uganda. A 26 year old female presented with a history of grinding pain in the limbs for over 20 years. Strong painkillers would temporally relieve the pain. She had an asthenic stature with generalised reduction in muscle bulk. Plain x-rays revealed the characteristic symmetrical thickening and sclerosis of the diaphyses of the appendicular skeleton and skull base, which is pathognomonic of Camurati-Engelmann's disease. Involvement of the metaphyses of these long bones as well as the metacarpal bones makes this an unusual case.
