Full-text available
Branching pattern of aortic arch (AA) has a direct impact on the outcomes of thoracic surgical and angiographic procedures. Since, geographical variations in the branching pattern of AA have been described, this descriptive cross-sectional study describes the AA variations in a Sri Lankan population compared to the available global data. For that,...

Background The accuracy of internal organ volume estimation done with ultrasound (US) was found to be multifactorial. Hence, we aimed to describe and validate the volume assessment of ultrasound and standard volume estimation formulae for different shaped intra-abdominal organs using spleens and kidneys. Materials and methods Dissected cadaveric k...

Neurological manifestations of SARS-CoV-2 are increasingly being recognised and can arise as a result of direct viral invasion, para-infectious or postinfectious immune mechanisms. We report a delayed presentation of COVID-19 postinfectious immune-mediated encephalitis and status epilepticus occurring in a 47-year-old woman 4 weeks after SARS-CoV-2...
Article
Full-text available
Background Association between early diagnosis of chronic kidney disease (CKD) and low morbidity and mortality rate has been proven. Thus, tools for early CKD diagnosis are vital. Ultrasonography has been widely used to diagnose and monitor the progression of CKD. Objectives To determine the performance of selected renal ultrasonographic parameter...

Objective: To evaluated the prevalence and some associated factors of basilar invagination (BI) in a group of Sri Lankan adults. Material and methods: Brain computed tomographic images (CT) of adults admitted to Teaching Hospital Rathnapura, Sri Lanka were studied, excluding subjects with craniofacial syndromes, cerebral or spinal pathologies. The...

Schwannoma typically a slow-growing tumour that bears the reputation of the most common benign peripheral nerve sheath tumour. Sciatic nerve schwannoma is rare (1%) tumour that can manifest with symptoms of sciatica. Diagnosis of schwannoma is often delayed, notably when presents with symptoms of sciatica

Abstract Introduction: Renal sizes are of immense use to diagnose renal pathologies. As ethnic variations are known to influence renal sizes, we aimed to assess the ethnic variations in bipolar renal length (RL) and kidney to body height ratio (KBR) of a young adult Sri Lankan population. Methods: Healthy adults were recruited, by excluding subjec...

Cerebral venous sinus thrombosis (CVST) is an uncommon disease entity. In contrast-enhanced computed tomography (CT) or magnetic resonance venography (MRV) images of the brain, CVST usually manifests as a filling defect of the dural venous sinuses. Brain parenchymal involvement in CVST can be ranged from parenchymal oedema to haemorrhagic infarctio...
Article
Background In image assisted volume estimation, the volume of the object is calculated with a formula, using linear measurements of the objects. Since the volume estimation accuracy is thought to be influenced by the shape of the object, the volume estimation error would be related to the calculation formula used. Purpose To evaluate the volume es...

Background Aetiology of chronic kidney disease (CKD) has shown geographical clustering. Renal ultrasound (USS) is used to diagnose CKD, but USS features are known to vary with aetiology of CKD. Objectives To describe aetiological factors and USS features of CKD. Methods Renal USS was performed in diagnosed adult CKD patients (n=100) and a control...

Full-text available
Ultrasonography (USS) and computer-tomography (CT) are frequently warranted for volume estimation of internal organs. Volume estimation accuracy is said to be influenced by the shape of the object. The scanner utilizes a formula to calculate the volume of a specific shaped object. Therefore the volume estimation error described for non globular obj...
Article
Full-text available
Background: Volume estimation of organs using two-dimensional (2D) ultrasonography is frequently warranted. Considering the influence of estimated volume on patient management, maintenance of its high accuracy is empirical. However, data are scarce regarding the accuracy of estimated volume of non-globular shaped objects of different volumes. Pur...

Full-text available
Introduction: Chronic kidney disease (CKD) is a global & local health problem. Serum creatinine (Scr) is an indicator of renal function. Ultrasound is a freely available safe, reliable imaging modality, commonly used to assess kidneys in CKD. Association of renal length and Scr in CKD is evaluated in this study, as such data is lacking for Sri Lank...

Dengue infection is a mosquito born endemic disease with rising trend in Sri Lanka. Diagnosis of DF is clinical, supported by investigations. The phase of illness, warning signs, hydration and hemodynamic status of the patient determine the need for hospitalization and fluid management. Fluid management is crucial in prognosis. Ultrasonography (USG...
