Background/Aims: This study aims to investigate the effect of a fermented rice drink with Lactiplantibacillus plantarum JSA22 on symptoms, blood tests, microbiomes, and fecal metabolites in patients with irritable bowel syndrome (IBS) who were overweight. Methods: Sixty overweight (body mass index ≥ 23 kg/m2 ) patients aged between 20 and 65 with IBS were enrolled. Patients were divided into 2 groups and administered either a fermented rice drink or an nonfermented rice drink for a month. The symptom questionnaire, blood samples, and stool samples for microbiome and metabolite were collected before and after the month of rice drink administration.The primary efficacy variable was the subject’s global assessment of IBS symptoms. Results: In both groups, global IBS symptoms, including abdominal pain, bowel habit, urgency, and abdominal distension, improved significantly (P < 0.01). The abdominal bloating was more significantly improved in the fermented rice drink group than in the nonfermented rice drink group (P < 0.05). Significant changes were not observed in metabolic syndrome-related blood tests or fecal metabolites in either group. However, microbiome analysis showed significant differences in genus levels before and after consuming fermented rice drink, such as in Blautia in stool (P = 0.020) and Prevotella (P = 0.017) and Oribacterium (P = 0.018) in saliva. Conclusions The fermented rice drink with L. plantarum JSA22 showed a beneficial effect in reducing abdominal distension in IBS patients. Bacteria that reduce visceral fat accumulation increased in the stool and saliva of patients who consumed fermented rice drinks.

We report the effective treatment of calcific tendinitis in the gluteus medius muscle with a single application of the barbotage technique. A 68-year-old man visited our hospital complaining of right hip pain with an intensity of 8 on a numeric rating scale. A simple radiograph of the right hip showed a calcific nodule at the insertion site of the gluteus medius tendon. The stage of the calcific lesion was inferred through the characteristics of the findings confirmed on radiographs. Ultrasonography was performed and the results were combined to determine the appropriate stage to apply the barbotage technique. He confirmed the pain relief effect after performing the intervention. After 1 month, it was confirmed that the calcific lesion was completely removed at follow-up.

Body donation trends in Korea have changed significantly over the last 3 decades. Establishing a body donation system will promote donations to universities for academic purposes. Yonsei University College of Medicine started its own body donation system in 1992, including documenting donors’ records. However, there has been no reported attempt to analyze the trend of these records, which could provide noteworthy information that can be interpreted for medical advances. This study performed a statistical analysis of the donors’ records between 1992 and 2019 to analyze the sociological and anthropological changes. Donor personal information such as sex, age, religion, and place and cause of death were extracted from the Yonsei University College of Medicine database. Our statistical analysis revealed significant correlations between donors’ records and the changes in the number of geriatric hospitals, religious beliefs, number of donations, and donor age.

Background: and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods: This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results: Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.

The goal of this study was to determine the characteristics of the horizontal cervical wrinkle and to investigate histological feature, especially with respect to elastin and collagen fiber. Histologic sample were harvested from two fresh adult cadavers where the cervical wrinkle is in the neck. The tissue sections were stained with hematoxylin and eosin (HE) or Masson's Trichrome. In sections of neck skin, keratinization was observed in the epidermis, and many collagen fibers were observed in the dermis layer as in other skin. Specifically, a lot of short and curly elastic fiber were observed between the collagen fibers in the dermis. These elastic fibers were not stained with eosin and observed in gray. This long ligament-like structures were observed in the dermis. The ligament-like structures were stained with dark red by trichrome. These results indicate that these ligament-like structures are neither typical ligament nor typical smooth muscles. The results obtained from present study showed a ligamentous structure originating from the fascial layer (platysma muscle or investing layer). The results may help to understand the reasons about the formation of horizontal cervical wrinkle.

PURPOSE: To describe technical methods for functional magnetic resonance imaging (fMRI) study with arterial spin labeling (ASL) compared to blood oxygenation level-dependent (BOLD) technique and discuss the potential of ASL for research and clinical practice. MATERIALS AND METHODS: Task-based (n = 1) and resting-state fMRI (rs-fMRI) (n = 20) were performed using ASL and BOLD techniques. Results of both techniques were compared. RESULTS: For task-based fMRI with finger-tapping, the primary motor cortex of the contralateral frontal lobe and the ipsilateral cerebellum were activated by both BOLD and ASL fMRI. For rs-fMRI of sensorimotor network, functional connectivity showed similar results between BOLD and ASL. CONCLUSION: ASL technique has potential application in clinical and research fields because all brain perfusion imaging, CBF measurement, and rs-fMRI study can be performed in a single acquisition.

Hanging is a common method of suicide that is being reported more frequently in many countries. Several complications including injuries to the cervical spine, neck vessels, and brain can occur after attempted suicide by hanging. There are only a few reports of brain computed tomography and magnetic resonance imaging of hanging victims. The most common abnormality was diffuse cerebral edema. A subarachnoid hemorrhage is an atypical complication by suicidal hanging. We report a case of a female patient who presented to an emergency department with altered mental status after attempting suicide by incomplete hanging. The patient was diagnosed with a non-aneurysmal and non-traumatic subarachnoid hemorrhage. This case shows that spontaneous subarachnoid hemorrhage can develop due to a sudden elevation of intracranial pressure, as occurs with hanging.
