A 65-year-old male patient complained of diplopia after a cataract surgery. He had esotropia of 18 prism diopters (PDs) at distant and near deviation, and therefore, we performed the Hess screen test to identify any abnormal eye movement. However, the indicator was found to be out of bounds, and therefore, the test could not be completed. Therefore, the test was subsequently performed with a 20 PD base-out Fresnel prism, and an abduction deficit was observed in the right eye, but not in the left eye. Therefore, we speculated that the patient had abducens nerve palsy in the right eye. The results obtained in the present study imply that performing the Hess screen test with the Fresnel prism may be very useful in diagnosing ambiguous abnormalities in patients with extraocular movement. The Hess screen test can be performed for patients with a strabismus of greater than 15 PD by using a Fresnel prism. Thus, a Fresnel prism may be useful for performing both the Hess screen test and Lancaster screen test.

This study aimed to explore a deep learning radiomics (DLR) model based on grayscale ultrasound images to assist radiologists in distinguishing between benign breast lesions (BBL) and malignant breast lesions (MBL). A total of 382 patients with breast lesions were included, comprising 183 benign lesions and 199 malignant lesions that were collected and confirmed through clinical pathology or biopsy. The enrolled patients were randomly allocated into two groups: a training cohort and an independent test cohort, maintaining a ratio of 7:3.

Although the connection between muscular strength and flatfoot condition is well-established, the impact of corrective exercises on these muscles remains inadequately explored. This study aimed to assess the impact of intrinsic- versus extrinsic-first corrective exercise programs on muscle morphometry and navicular drop in boys with flexible flatfoot. Twenty-five boys aged 10-12 with flexible flatfoot participated, undergoing a 12-week corrective exercise program, with a shift in focus at six weeks.

The prevalence of prostate-specific antigen (PSA) testing has consistently fallen for several years. This study explored how the decreasing trend differs by selected variables and reasons for taking the PSA test. Analyses involved men, aged 40 years or older, who completed the Behavior Risk Factor Surveillance System (BRFSS) survey in even number years from 2008 through 2022.

Background: Women's preferences for time allocation reveal how they would like to prioritise market work, family life, and other competing activities. Whilst preferences may not always directly translate to behaviour, they are an important determinant of intention to act.
Objective: We present the first study to apply a discrete choice experiment (DCE) to investigate time allocation preferences among women diagnosed with breast cancer and women without a cancer diagnosis.

Visual hallucinations (VH) and pareidolia, a type of minor hallucination, share common underlying mechanisms. However, the similarities and differences in their brain regions remain poorly understood in Parkinson's disease (PD). A total of 104 drug-naïve PD patients underwent structural MRI and were assessed for pareidolia using the Noise Pareidolia Test (NPT) were enrolled.
