Mounier-Kuhn syndrome (MKS) or congenital tracheobronchomegaly is a rare disorder characterized by marked dilatation of the trachea and main bronchi, bronchiectasis, and recurrent respiratory tract infections. The etiology of this disorder is uncertain and the clinical presentation is variable. The diagnosis is usually made based on the characteristic computed tomography (CT) scan findings. This report describes a case of a 43-year-old man presenting with persistent cough and recurrent lower respiratory tract infections since childhood associated with copious amounts of purulent sputum, difficulty in breathing, and weight loss. In addition, he reported palpitations, dyspnea, orthopnea, abdominal and lower limb swelling. The chest X-ray showed a dilated trachea (35mm) and bronchi (26mm (right) and 27mm (left)) with cystic bronchiectasis and reticulolinear opacities predominantly involving the middle and lower lung zones. Chest CT scan confirmed the diagnosis of MKS as evidenced by dilated trachea and bronchi complicated by diverticula formation. Electrocardiogram, echocardiography and abdominal ultrasound scan showed features of right-sided heart failure secondary to pulmonary hypertension. MKS, although rare, should be considered as a possible diagnosis in patients presenting with productive chronic cough, recurrent pneumonia, or incomplete response to appropriate antibiotic therapy for pneumonia.

Background Computed Tomographic (CT) scanning of the head can detect acute intracranial injury and help to identify patients requiring neurosurgical intervention. The inappropriate utilization of CT scan strains meagre imaging resources especially in resource-constrained settings and risks the patients to unnecessary radiation. The Canadian CT head rule (CCHR) is a validated clinical tool used to predict mild head injury patients that will have a clinically significant intracranial injury on head CT scan. This reduces the number of requested CT scans while at the same time ensuring that those who would benefit from it are easily identified. However, this tool has not been previously applied in many low income settings where it would be very useful. Objective To determine the appropriateness of head CT scans performed among patients with mild traumatic head injury based on the Canadian CT head rule (CCHR). Methods This was a cross sectional study conducted at the emergency department of Mulago Hospital involving 259 adults clinically diagnosed with mild head injury with a head CT scan performed. They were assessed using the CCHR for a prediction of whether a head CT scan was appropriate or inappropriate. The proportion of appropriate head CT scans was obtained. The participants were followed up to assess their health status. Results The common abnormal CT scan findings were comminuted and depressed skull fractures. The proportion of appropriate head CT scans performed based on the CCHR was 70.7%. Most participants with positive CT scan findings were classified as appropriate when the CCHR was applied. 81.6% (n = 62) of the participants whose CT scans were classified as inappropriate had normal findings. There was a statistically significant association between categories of CCHR classification (appropriate vs inappropriate) and CT scan findings (normal vs neurologically insignificant). Conclusion About one-third of head CT scans performed in this study were inappropriate by applying the CCHR. Avoidance of CT scan in such patients is unlikely to miss any important injuries. Findings from the study can guide the adoption and adaptation of CCHR use in emergency departments.

Background Carotid Atherosclerotic Disease (CAD) Doppler findings including carotid artery stenosis, thickened intima media thickness, and high-risk atherosclerotic plaques are associated with increased risk of stroke and symptomatic cerebrovascular disease. However, few studies have explored these Doppler characteristics among stroke patients in Africa. This study, therefore, investigates these carotid artery Doppler characteristics among stroke patients in Uganda.Methods A hospital-based cross-sectional study of 95 stroke patients attending two national referral hospitals in Uganda between March and July 2022. Following the caption of their sociodemographic and clinical characteristics, they underwent Doppler sonography of the extracranial carotid arteries using a standard carotid Doppler protocol. Multivariate logistic regression was used to determine factors associated with abnormal carotid Doppler parameters (i.e., carotid intima-media thickness, carotid stenosis).Results The mean age of the study participants was 61 ± 13 years with 60% (57/95) of the participants being male. Most participants had an ischemic stroke (67%), hypertension (76.4%), and used alcohol (58.9%). The prevalence of significant carotid stenosis in participants with ischemic stroke was 12.5% (8/64) (i.e., 7.8% had severe carotid stenosis and 4.7% had moderate stenosis). The prevalence of high carotid intima media thickness (CIMT) and atherosclerotic plaques were 31.6% (30/95) and 26.3% (25/95), respectively. Most atherosclerotic plaques were echogenic. Age above 60 years (adjusted odds ratio [aOR] = 5.2, 95% Confidence Interval [CI]:1.97-14; p < 0.010), high low-density lipoprotein cholesterol (aOR = 4.2, 95% CI: 1.29–8.79; p = 0.013) increased the likelihood of having abnormal CIMT.Conclusion The burden of carotid atherosclerotic disease is increasing among stroke patients in Uganda. Large-scale epidemiological studies are needed to further profile the disease in high risk populations.

We present a histologically proven mucinous adenocarcinoma of the colon in a 40 year old female from Gulu, Northern Uganda. Her elder sister died at 25 years with advanced adenocarcinoma of colon similarly with her mother who died of the same illness 10 years apart. Using the Amsterdam criteria for the diagnosis of the carcinoma of the colon, this is descriptive of Hereditary Non Polyposis Colorectal Carcinoma (HNPCC). Blood examinations revealed microcytic hypochromic anaemia. The Renal and Liver function parameters were essentially normal. The abdominal ultrasonography showed an ill-defined mass in the right hypochondrial region which was heterogeneous with central echogenicity approximately 7.2cm wide and with no intra-abdominal lymphadenopathy or ascitis. At laparotomy, the sonographic findings were confirmed with a demonstrable mass in the hepatic flexure of the colon with hyperemic areas on its serosa. Macroscopically, there was an annular fungating mass with a central necrosis in the hepatic flexure measuring over 7.0cm. Histology of the colonic tumour showed a mucinous adenocarcinoma of the colon (Duke's B). This finding highlights the occurrence of colonic adenocarcinoma in the young person in Northern Uganda, a finding which draws the attention of the medical community towards having a higher index of suspicion for carcinoma of the colon in patients with similar presentation.
