Introduction: Benign positional paroxysmal vertigo (BPPV) stands as the commonest cause for vertigo. It accounts for 20% of all cases of vertigo, even with its high prevalence rate it often goes underdiagnosed and undertreated. Development of the consensus document by the Bárány society's International Classification of Vestibular Disorders (ICVD)significantly facilitates the diagnosis of BPPV and its variants. This study assesses the utilisation of ICVD criteria for managing BPPV.
Methodology: This is a cross-sectional descriptive study conducted at a tertiary care hospital in Northern India spanning from November 1, 2022, to November 30, 2023. A total of 110 participants diagnosed with BPPV were enrolled consecutively. All participants underwent Dix-Hallpike and supine log roll positional maneuvers. Diagnosis was made based on the history and type of nystagmus seen, and classified as per the ICVD criteria.
Results: Posterior semicircular canalolithiasis (pc-BPPV) accounted for 25.45% of cases and horizontal canal canalolithiasis (hc-BPPV) accounted for 20.91% of cases. Probable BPPV, spontaneously resolved (pBPPVsr) was diagnosed in 16.36% of participants and possible BPPV(pBPPV) was diagnosed in 18.18% of participants. Multiple canal BPPV (mc-BPPV) accounted for 17.27% of cases. One participant was diagnosed with horizontal canal cupulolithiasis and anterior canal canalolithiasis respectively. No participant was diagnosed with posterior canal cupulolithiasis.
Conclusion: The most common type of BPPV was pc-BPPV followed by hc-BPPV. The affected canal in possible BPPV, can be identified, and appropriate repositioning maneuvers are effective in treating them as well as aids in confirming the diagnosis. The diagnostic clarity provided by ICVD, aids in effective management of BPPV. More studies with larger sample size are required to further validate its clinical utility.

Objective: Rapid on-site evaluation (ROSE) of respiratory cytology specimens is a critical technique for accurate and timely diagnosis of lung cancer. However, in China, limited familiarity with the Diff-Quik staining method and a shortage of trained cytopathologists hamper utilization of ROSE. Therefore, developing an improved deep learning model to assist clinicians in promptly and accurately evaluating Diff-Quik stained cytology samples during ROSE has important clinical value.

Background: This study aims to examine the relationship between maternal antenatal and postnatal depressive disorders and the risk of disruptive behavioural disorders (DBDs) in offspring, including conduct disorder (CD) and oppositional defiant disorder (ODD), to enhance understanding and address gaps in the literature.
Methods: We utilised a large administrative health dataset from New South Wales (NSW), Australia. Maternal perinatal depressive disorders and offspring DBDs were identified using International Classification of Diseases (ICD-10) codes.

Lung cancer remains a significant health concern worldwide, prompting ongoing research efforts to enhance early detection and diagnosis. Prior studies have identified key challenges in existing approaches, including limitations in feature extraction, interpretability, and computational efficiency. In response, this study introduces a novel deep learning (DL) framework, termed the Improved CenterNet approach, tailored specifically for lung cancer detection.

Background: Spinal pain affects up to 30% of school-age children and can interfere with various aspects of daily life, such as school attendance, physical function, and social life. Current assessment tools often rely on parental reporting which limits our understanding of how each child is affected by their pain. This study aimed to address this gap by developing MySpineData-Kids ("MiRD-Kids"), a tailored patient-reported questionnaire focusing on children with spinal pain in secondary care (Danish hospital setting).
