Povzetek: Renal pathology is common in childhood. Imaging plays a critical role in the diagnosis of kidney diseases and encompasses a range of modalities. Advanced imaging is typically performed in specialised paediatric hospitals, where experienced paediatric radiologists are familiar with the relevant techniques, protocols, indications, and limitations. However, children are often first admitted to general hospitals, where radiologists may have more limited experience in paediatric imaging. Renal cysts in children differ from those in adults, most commonly presenting as cystic kidney diseases. In the majority of cases, ultrasound (US) is the sole diagnostic modality required. Imaging is not necessary for the diagnosis of urinary tract infection (UTI), but it is essential for detecting underlying anomalies and potential complications. Urinary tract dilatation is a common finding in children; however, only up to 30% of cases require further evaluation to diagnose urinary tract obstruction or vesicourinary reflux. Urolithiasis is relatively uncommon in children and is primarily diagnosed with US, although computed tomography (CT) may occasionally be necessary. Solid renal lesions identified on US should be further evaluated in highly specialised paediatric centres. Mild to moderate renal trauma can be diagnosed and monitored using US, whereas CT remains the modality of choice for assessing severe trauma.

Povzetek: Objectives: Conventional plaque assessment methods, such as clinical indices and planimetry, rely on plaque-disclosing agents and may overemphasize thin biofilm areas due to plaque thickness variations. This study introduces a digital 3D method to quantify and visualize dental plaque volume from consecutive intraoral scans (IOS) and compares it with the Turesky Modification of the Quigley-Hein Plaque Index (TMQHPlI) and planimetry. Methods: After professional supragingival debridement at baseline (T0), fifteen participants refrained from oral hygiene for four days (T4). De novo plaque formation was assessed at T4 using TMQHPlI after application of a two-tone (pink/purple) plaque-disclosing agent. IOSs (3Shape TRIOS 4) were obtained at T0 and T4. Plaque accumulation was quantified using color-coded IOS comparisons with the Volumetric Plaque Index (VPI) and Adjusted VPI (AVPI). Machine learning (Trainable Weka Segmentation) was used to calculate the Planimetric Plaque Index (PPI). Results: A correlation between plaque surface area and volume was observed only for purple/mature plaque (p = 0.043). Early plaque growth was dominated by expansion of pink-stained, newly formed plaque. Once more than one-third of the surface was covered, further increases resulted mainly from vertical thickening rather than lateral spread. Conclusions: 3D volumetric analysis offers a comprehensive, objective, and clinician-friendly method for assessing dental biofilms. Clinical relevance: The proposed 3D approach enables accurate monitoring of plaque accumulation and maturation, improving personalized oral hygiene assessment, patient education, and clinical decision-making.

Povzetek: Juvenile Idiopathic Arthritis (JIA) is a major contributor to chronic diseases, affecting around 1–2 in 1000 children under the age of 16. With modern treatments, the morbidity has been reduced; however, there is increasing evidence that many, if not most, children with JIA will have a chronic disease with ongoing activity into adulthood. Many studies discuss the possibility of an early window of opportunity in which patients have the best chance of responding to therapy, thereby underscoring the importance of timely and appropriate imaging. Children typically present at 4–5 years of age with one or more stiff and painful joints. If JIA is suspected, the child should undergo an ultrasound of the involved joint(s), performed by a radiologist with experience in paediatric imaging. If this is normal, with no abnormal laboratory tests and low clinical suspicion of JIA, no further imaging is required. If there is inconsistency between ultrasound and clinical findings, then they should proceed to MRI, including intravenous contrast, of the involved joint. Additional radiographs, or low-dose CT for the axial joints to examine for potential destructive change, deformation, or growth abnormalities, should be considered. In children presenting with monoarthritis, bacterial infection must be ruled out.
