Criterion-Related Validity of the Cognitive Function Score with the Revised Hasegawa's Dementia Scale and the Bedriddenness Rank with the Barthel Index and the Katz Index: A Multi-Center Retrospective Study.

Introduction: The cognitive function score (CFS) is a public scale for assessing the activities of daily living (ADL) in older adults with dementia in Japan. In contrast, the scores of the revised Hasegawa's dementia scale (HDS-R), an easy-to-use dementia screening tool developed in Japan, are significantly correlated with mini-mental state examination scores and are widely utilized in various countries. This novel study aimed to elucidate the previously unexplored criterion-related validity of the CFS and HDS-R and the Bedriddenness Rank (BR), Barthel index (BI), and Katz index (KI).

Potential Indicators of Intestinal Necrosis in Portal Venous Gas: A Case Report of an 82-Year-Old Woman on Long-Term Hemodialysis with Ascites and Pneumatosis Coli.

BACKGROUND Several factors have been reported as possible predictors of intestinal necrosis in patients with portal venous gas (PVG). We describe potential indicators of intestinal necrosis in PVG identified by contrasting 3 episodes of PVG in a patient on hemodialysis against previously verified factors. CASE REPORT An 82-year-old woman undergoing hemodialysis was admitted to our hospital thrice for acute abdominal pain.

Validation and Improvement of the Saga Fall Risk Model: A Multicenter Retrospective Observational Study.

Purpose: We conducted a pilot study in an acute care hospital and developed the Saga Fall Risk Model 2 (SFRM2), a fall prediction model comprising eight items: Bedriddenness rank, age, sex, emergency admission, admission to the neurosurgery department, history of falls, independence of eating, and use of hypnotics. The external validation results from the two hospitals showed that the area under the curve (AUC) of SFRM2 may be lower in other facilities. This study aimed to validate the accuracy of SFRM2 using data from eight hospitals, including chronic care hospitals, and adjust the coefficients to improve the accuracy of SFRM2 and validate it.

Heidenhain Variant of Sporadic Creutzfeldt-Jakob Disease with a Variety of Visual Symptoms: A Case Report with Autopsy Study.

BACKGROUND Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal disease caused by the change of prion protein (PrP). Affected patients present with rapidly progressive cognitive dysfunction, myoclonus, or akinetic mutism. Diagnosing the Heidenhain variant of sCJD, which initially causes various visual symptoms, can be particularly difficult.

A Prospective Observational Study Conducted at a Single Center in Japan to Validate a Previously Developed Predictive Formula of In-Hospital Mortality for Patients Aged ≥65 Years with Endogenous Diseases Transported by Ambulance.

BACKGROUND In 2019, we developed a predictive formula of in-hospital mortality for inpatients aged ≥65 years transported by ambulance for endogenous diseases. In this study, we aimed to validate this previously developed predictive formula. MATERIAL AND METHODS In this single-center prospective observational study, we enrolled all patients aged ≥65 years who were transported by ambulance and admitted to an acute care hospital in Japan for endogenous diseases.

Late-Onset Ornithine Transcarbamylase Deficiency Complicated with Extremely High Serum Ammonia Level: Prompt Induction of Hemodialysis as the Key to Successful Treatment.

BACKGROUND Ornithine transcarbamylase deficiency (OTCD) is an X-linked semi-dominant disorder, causing possible fatal hyperammonemia. Late-onset OTCD can develop at any time from 2 months after birth to adulthood, accounting for 70% of all OTCDs. CASE REPORT A 35-year-old man with chronic headaches stated that since childhood he felt sick after eating meat.

Unilateral syphilitic optic neuritis without meningitis or uveitis.

A 69-year-old man with left eye pain and visual impairment was diagnosed with syphilitic optic neuritis, who was successfully treated by penicillin. Although it is difficult to decide syphilis as the direct cause of optic neuritis, it is essential to diagnose syphilis in every patient with optic neuritis.

Relationships between sites of abdominal pain and the organs involved: a prospective observational study.

Objectives: Abdominal pain is one of the most frequent chief complaints in primary care settings. The aim of the present study was to determine the positive likelihood ratios (PLRs) and negative likelihood ratios (NLRs) of the relationships between the sites of abdominal pain and the organs involved.

Design: Prospective observational study.

Pegfilgrastim-associated large-vessel vasculitis developed during adjuvant chemotherapy for breast cancer: A case report and review of the literature.

Introduction: Granulocyte colony-stimulating factor (G-CSF) is widely used as a neutrophil supportive therapy in breast cancer chemotherapy. Common adverse events of G-CSF include bone pain, headache, and fatigue; however, reports of G-CSF-associated vasculitis are few.

Case Report: A 66-year-old woman who had undergone surgery for breast cancer received adjuvant chemotherapy with prophylactic use of pegfilgrastim (peg-G).

Proliferative Fasciitis/Myositis Involving the Facial Muscles Including the Masseter Muscle: A Rare Cause of Trismus.

BACKGROUND Proliferative fasciitis/myositis is a benign disease that can be treated conservatively. However, some patients are mistakenly treated surgically because of a misdiagnosis of the condition as a malignant tumor. CASE REPORT A 50-year-old Japanese man developed swelling in his left cheek 12 days before admission; he developed a fever and trismus 3 days later.
