Endometriosis is a relatively common gynecological condition in women of reproductive age. The rectosigmoid region is the most commonly affected segment when the gastrointestinal tract is involved. A differential diagnosis of colorectal neoplasia is difficult because of the similar clinical, endoscopic, and radiology findings. A 42-year-old female presented with abdominal distention and was subsequently diagnosed with a large bowel obstruction in the rectum. A temporary colostomy was performed, and endoscopy revealed a rectal mass obstructing the rectum. The biopsy showed normal mucosa, and it was difficult to exclude rectal malignancies even after the imaging workup. Endoscopic ultrasound demonstrated a hypoechoic lesion below the rectal mucosa, and fine needle aspiration confirmed the diagnosis of bowel endometriosis. Bowel endometriosis is a challenging diagnosis. Endoscopic ultrasound-guided fine-needle aspiration is useful for acquiring adequate samples for histological confirmation and a definitive diagnosis of bowel endometriosis.

BACKGROUND AND PURPOSE: Excessive daytime sleepiness (EDS) is a common complaint among patients with Parkinson's disease (PD). Several factors have been associated with EDS in PD, especially neuropsychiatric symptoms. This study aimed to determine the relationships between neuropsychiatric symptoms, sociodemographic and clinical parameters, and EDS in PD. METHODS: This cross-sectional study analyzed 85 patients with PD. All patients underwent socioeconomic and clinical data evaluations followed by a psychiatric interview and a neurological examination, including the assessment of sleep features. Patients were divided into two groups according to the presence or absence of EDS, which was defined as a score higher than 10 on the Epworth Sleepiness Scale. Binary logistic regression was performed in order to describe the predictors of EDS. RESULTS: We found that EDS affects 40% of PD patients and is associated with older age, restless legs syndrome, depressive and anxious symptoms, and worse sleep quality. In the multivariate analysis, older age, levodopa use, and worse sleep quality remained as significant predictors of EDS in PD. CONCLUSIONS: Nighttime sleep problems, older age, and levodopa use are significantly associated with EDS in PD. A careful assessment and the management of sleep problems in PD patients might help to improve their quality of life.

Purpose: This investigation was conducted to elucidate the effects of eugenol on bladder contractility through experimental and in silico approaches. Methods: To assess the impact of eugenol on muscular contractility, longitudinal strips of bladder tissue, measuring 2 mm by 6 mm, were mounted in perfusion chambers connected to an isometric force transducer. Furthermore, molecular docking studies were conducted to explore the potential of eugenol to target the M3 muscarinic acetylcholine receptor (M3R) and voltage-operated calcium channels (VOCCs) in muscle cells, utilizing in silico techniques. Results: Eugenol exhibited a concentration-dependent inhibitory effect on both the phasic and tonic components of the contraction induced by 60mM K+ and carbachol, completely suppressing this contraction at a concentration of 3mM. Additionally, eugenol inhibited the concentration-contraction curve elicited by Ba2+. Conclusions The in vitro and in silico results suggest that the mechanism of eugenol likely involves blockade of VOCCs and/or M3R, implicating eugenol as a promising molecule for the treatment of overactive bladder.
