ABSTRACT
INTRODUCTION: Device-aided therapy (DAT) is an established treatment for improving the quality of life (QOL) in individuals with advanced Parkinson's disease (APD). Criteria for starting DAT, including motor and non-motor symptoms, have been proposed. However, it remains unclear whether QOL differences among patients with APD influence DAT introduction. Therefore, we aimed to investigate QOL differences between patients with and without DAT introduction. METHODS: This retrospective observational cross-sectional study included 245 patients with PD who were followed up between January 1, 2020, and June 30, 2022. We defined cases that underwent DAT introduction after evaluation as "planned-DAT" and those that did not as "not-planned-DAT." We performed between-group comparisons of the PD questionnaire-39 (PDQ-39) summary index (SI) in patients with APD who met the 5-2-1 criteria (≥5 times the oral levodopa dose/day, ≥2 h of "off" symptoms/day, and ≥ 1 h of troublesome dyskinesia/day). RESULTS: Seventy-nine patients met the inclusion criteria for APD (median age: 68 [61.0-73.0] years; 62.8% [N = 52] women). The PDQ-39 SI scores were higher in the planned-DAT group (N = 12) than in the not-planned-DAT group (N = 67) (29.2 [22.1-33.6] vs. 19.0 [10.3-49.6] points, P < 0.05). After propensity-score matching according to age and sex, the PDQ-39 SI scores remained higher in the planned-DAT (N = 9) than in the not-planned-DAT group (N = 18) (40.0 [25.4-60.0] vs. 18.5 [7.9-46.8] points, P < 0.05). CONCLUSIONS: Our results suggest that QOL assessment using PDQ-39 can be used to identify patients eligible for DAT.

PURPOSE: Brain MRI with high spatial resolution allows for a more detailed delineation of multiple sclerosis (MS) lesions. The recently developed deep learning-based reconstruction (DLR) technique enables image denoising with sharp edges and reduced artifacts, which improves the image quality of thin-slice 2D MRI. We, therefore, assessed the diagnostic value of 1 mm-slice-thickness 2D T2-weighted imaging (T2WI) with DLR (1 mm T2WI with DLR) compared with conventional MRI for identifying MS lesions. METHODS: Conventional MRI (5 mm T2WI, 2D and 3D fluid-attenuated inversion recovery) and 1 mm T2WI with DLR (imaging time: 7 minutes) were performed in 42 MS patients. For lesion detection, two neuroradiologists counted the MS lesions in two reading sessions (conventional MRI interpretation with 5 mm T2WI and MRI interpretations with 1 mm T2WI with DLR). The numbers of lesions per region category (cerebral hemisphere, basal ganglia, brain stem, cerebellar hemisphere) were then compared between the two reading sessions. RESULTS: For the detection of MS lesions by 2 neuroradiologists, the total number of detected MS lesions was significantly higher for MRI interpretation with 1 mm T2WI with DLR than for conventional MRI interpretation with 5 mm T2WI (765 lesions vs. 870 lesions at radiologist A, < 0.05). In particular, of the 33 lesions in the brain stem, radiologist A detected 21 (63.6%) additional lesions by 1 mm T2WI with DLR. CONCLUSION: Using the DLR technique, whole-brain 1 mm T2WI can be performed in about 7 minutes, which is feasible for routine clinical practice. MRI with 1 mm T2WI with DLR enabled increased MS lesion detection, particularly in the brain stem.

BACKGROUND: Previously, we revealed that coadministration of particular enteral nutrients (ENs) decreases plasma concentrations and gastric absorption of phenytoin (PHT), an antiepileptic drug, in rats; however, the mechanism has not been clarified. METHODS: We measured the permeability rate of PHT using a Caco-2 cell monolayer as a human intestinal absorption model with casein, soy protein, simulated gastrointestinal digested casein protein (G-casein or P-casein) or simulated gastrointestinal digested soy protein (G-soy or P-soy), dextrin, sucrose, degraded guar gum, indigestible dextrin, calcium, and magnesium, which are abundant in the ENs, and measured the solution's properties. RESULTS: We demonstrated that casein (40 mg/ml), G-soy or P-soy (10 mg/ml), and dextrin (100 mg/ml) significantly decreased the permeability rate of PHT compared with the control. By contrast, G-casein or P-casein significantly increased the permeability rate of PHT. We also found that the PHT binding rate to casein 40 mg/ml was 90%. Furthermore, casein 40 mg/ml and dextrin 100 mg/ml have high viscosity. Moreover, G-casein and P-casein significantly decreased the transepithelial electrical resistance of Caco-2 cell monolayers compared with casein and the control. CONCLUSION: Casein, digested soy protein, and dextrin decreased the gastric absorption of PHT. However, digested casein decreased PHT absorption by reducing the strength of tight junctions. The composition of ENs may affect the absorption of PHT differently, and these findings would aid in the selection of ENs for orally administered PHT.

Amyotrophic lateral sclerosis (ALS) is one of the differential diagnoses of diseases that occur in adulthood and lead to progressive generalized muscle weakness. Neuronal intranuclear inclusion disease (NIID) is a disease in which histopathologically eosinophilic nuclear inclusion bodies are found in various systems. Both familial and sporadic forms of the disease have been reported. Most cases of sporadic NIID are of the dementia type, in which the main symptom is dementia at the first onset. Familial NIID is more diverse, with the main dominant symptoms being muscle weakness (NIID-M), dementia (NIID-D), and parkinsonism (NIID-P). Furthermore, recently, a GGC-repeat expansion in the Notch 2 N-terminal like C (NOTCH2NLC) gene, which produces a toxic polyglycine-containing protein (uN2CpolyG) in patients with NIID, has been associated with the pathogenesis of ALS. These results suggest that sporadic NIIDs may have more diverse forms. To date, no autopsy cases of NIID patients with an ALS phenotype have been reported. Here, we describe the first autopsy case report of a patient with sporadic NIID who had been clinically diagnosed with ALS. A 65-year-old Japanese man with no family history of neuromuscular disease developed progressive muscle atrophy and weakness in all limbs. The patient was diagnosed with ALS (El Escoriral diagnostic criteria: probable ALS, laboratory-supported ALS). He had no cognitive dysfunction or neuropathies suggestive of NIID. He required respiratory assistance 48 months after onset. He died of pneumonia at the age of 79 years. Postmortem examinations revealed neuronal loss in the spinal anterior horns and motor cortex. In these affected regions, eosinophilic, round neuronal intranuclear inclusions were evident, which were immunopositive for ubiquitin, p62, and uN2CpolyG. No Bunina bodies or TDP-43-positive inclusions were observed in the brain or spinal cord. Our findings suggest that a small proportion of patients with NIID can manifest a clinical phenotype of ALS. Although skin biopsy is commonly used for the clinical diagnosis of NIID, it may also be useful to identify cases of NIID masquerading as ALS.
ABSTRACT
OBJECTIVES: Forced vital capacity (FVC) is recommended as a respiratory function test in patients with amyotrophic lateral sclerosis (ALS). However, in ALS associated with orofacial palsy, FVC may be an unreliable test. Slow vital capacity (SVC) is an easier and more reliable test even in cases with bulbar symptoms. However, it remains unclear whether respiratory function tests using SVC and FVC are associated with prognosis after percutaneous endoscopic gastrostomy (PEG) placement. This study aimed to confirm whether both SVC and FVC are related to prognosis after PEG placement in patients with ALS. MATERIALS AND METHODS: We conducted this retrospective observational cohort study of 69 consecutive patients diagnosed with sporadic ALS who underwent PEG placement between July 2007 and February 2020. We analyzed the association with mortality 6 months after PEG placement and evaluated long-term prognosis. RESULTS: Forty-four patients met the inclusion criteria. In cases with decreased SVC (p < .01) and FVC (p < .01), a significant difference was observed in mortality 6 months after PEG placement, with an optimal cut-off of SVC ≤57.4% (sensitivity, 0.828; specificity, 0.867) and FVC ≤57.3% (sensitivity, 0.828; specificity, 0.867). Multivariate analysis showed that onset age ≥ 65 years (p < .05), SVC ≤57.4% (p < .01), and FVC ≤57.3% (p < .01) were associated with survival after PEG placement. CONCLUSIONS: SVC, like FVC, is an important prognostic factor after PEG placement in patients with ALS, and there is a possibility that evaluation using SVC can complement respiratory function testing even in cases where the evaluation of FVC is limited.

BACKGROUND: Guillain-Barré syndrome (GBS) and spinal epidural abscess (SEA) are known as mimics of each other because they present with flaccid paralysis following an infection; however, they differ in the main causative bacteria. Nevertheless, the two diseases can occur simultaneously if there is a preceding Campylobacter infection. Here, we report the first case of SEA with GBS following Campylobacter coli infection. CASE PRESENTATION: A 71-year-old Japanese man presented with progressive back pain and paralysis of the lower limbs following enteritis. Magnetic resonance imaging showed a lumbar epidural abscess that required surgical decompression; therefore, surgical drainage was performed. Blood cultures revealed the presence of C. coli. Despite surgery, the paralysis progressed to the extremities. Nerve conduction studies led to the diagnosis of GBS. Anti-ganglioside antibodies in the patient suggested that GBS was preceded by Campylobacter infection. Intravascular immunoglobulin therapy attenuated the progression of the paralysis. CONCLUSIONS: We report a case of SEA and GBS following Campylobacter infection. A combination of the two diseases is rare; however, it could occur if the preceding infection is caused by Campylobacter spp. If a cause is known but the patient does not respond to the corresponding treatment, it is important to reconsider the diagnosis based on the medical history.

Biomarkers of tumour response to radiotherapy may help optimise cancer treatment. The aim of the present study was to identify changes in extracellular microRNAs (miRNAs) as a biomarker of radiation-induced damage to human colorectal cancer cells. HCT116 cells were exposed to increasing doses of X-rays, and extracellular miRNAs were analysed by microarray. The results were correlated with the frequency of micronuclei. A total of 59 miRNAs with a positive correlation and 4 with a negative correlation between dose (up to 6 Gy) and extracellular miRNA expression were identified. In addition, for doses between 0 and 10 Gy, 12 miRNAs among those 59 miRNAs with a positive correlation were identified; for these extracellular miRNAs, a significantly positive correlation was observed between their expression and the frequency of micronuclei for doses up to 10 Gy. These results suggest that specific miRNAs may be considered as cell damage markers and may serve as secreted radiotherapy response biomarkers for colorectal cancer; however, the results must be further validated in serum samples collected from patients undergoing radiotherapy.
ABSTRACT
A 73-year-old man was presented with epigastric pain and indicated high CA19-9 levels, and computed tomography detected a tumor in the uncinate process of the pancreas infiltrated duodenum and superior mesenteric artery. The patient was diagnosed with borderline resectable pancreatic carcinoma and received neoadjuvant chemotherapy with gemcitabine and S-1. During neoadjuvant chemotherapy, the patient also received radiotherapy to control duodenal bleeding. After neoadjuvant chemotherapy, stable disease(SD)was proven on the Response Evaluation Criteria in Solid Tumors(RECIST), and subtotal stomach-preserving pancreaticoduodenectomy was performed. The pathological findings showed pancreatic adenosquamous carcinoma. After 7 days postoperatively, hepatic metastasis was detected, and after 78 days postoperatively, the patient died.

A 71-year-old female was referred to our hospital for abdominal distention and anorexia. Gastrointestinal endoscopy revealed wall thickening of the entire circumference. Abdominal CT scan showed diffuse thickening of the stomach, but there was no obvious metastasis. Scirrhous gastric cancer was strongly suspected, but endoscopic biopsies could not demonstrate malignant features. Staging laparoscopy was performed. There was a small amount of ascites and numerous peritoneal dissemination. She was diagnosed with gastric cancer pStage â £(pT4a, NX, H0, M1, P1, CY1)without HER2 positivity. We experienced a case of scirrhous gastric cancer in which staging laparoscopy was useful for histological diagnosis and staging.

Continuous intrajejunal infusion of levodopa-carbidopa intestinal gel (LCIG) is an established device-aided therapy for advanced Parkinson's disease (PD). Phytobezoar associated with LCIG is a rare device-related complication and presents with exacerbations of gastrointestinal and PD symptoms. We herein report the case of a phytobezoar that was formed at a knot on the pigtail-shaped J-tube and developed only in association with postprandial abdominal pain, similar to a feeling of a tube being pulled in without an exacerbation of PD symptoms. Such abdominal pain may be a warning sign of phytobezoar in LCIG-treated patients. Despite device-related complications, high-pressure alarms are not always present, and PD symptoms are not always exacerbated.

Mild palmar digital neuropathy may be underestimated because selective nerve conduction studies (NCS) of the palmar digital nerve are challenging. We herein report two cases of palmar digital neuropathy. We performed sensory NCS in each finger using the standard approach. Both cases showed a decrease in the amplitude of sensory nerve action potential (SNAP) in the localized finger. Furthermore, the sensory nerve inching test identified the lesion site. When performing NCS in patients with finger sensory impairment, we recommend recording the SNAP in each finger using standard NCS at the wrist, as well as sensory nerve inching testing.

A 66-year-old man presented with a 6-day history of progressive posterior cervical pain that included lower back pain and fever. Neurological examinations revealed neck stiffness. Computed tomography demonstrated convexity subarachnoid hemorrhage. A spinal T2-weighted image revealed a hypointense signal lesion with contrast enhancement of the intradural extramedullary space at Th12-L1. Digital subtraction angiography showed a fusiform aneurysm with a 10 mm diameter in the artery of Adamkiewicz. We diagnosed the patient's condition as a ruptured aneurysm of the artery of Adamkiewicz. By day 41 the aneurysm had disappeared following conservative treatment. Aneurysms arising from the artery of Adamkiewicz are extremely rare and can cause both convexity and spinal subarachnoid hemorrhages. Clinicians should therefore look for spinal lesions if patients with convexity subarachnoid hemorrhage of an unknown origin have lower back pain as their initial symptom.

BACKGROUND: The risk of venous thromboembolism (VTE) after surgery for malignancy in Japanese patients is unclear; therefore, standard prevention protocols have not been established, especially for minimally invasive procedures. We aimed to investigate the additional effect of low molecular weight heparin (LMWH) on prevention of VTE after laparoscopic surgery for gastrointestinal malignancy. STUDY DESIGN: From February 2013 to January 2017, 400 patients scheduled for laparoscopic surgery were included. Cases were randomly allocated to the physical therapy group (Control group; 201 patients) or to the combination-therapy group (LMWH group; 199 patients), in which enoxaparin sodium (20 mg [= 2000 IU] twice a day) was administered for 1 week postoperatively in addition to the physical therapy. A diagnosis of VTE was made by contrast-enhanced CT or ultrasonography when symptomatic or D-dimer was ≥10 µg/mL. RESULTS: VTE was observed in 1.2% and 4.0% of patients in the LMWH and Control groups, respectively (odds ratio [OR] 0.3, 95% confidence interval [CI] 0.03-1.53). Pulmonary embolism was confirmed only in the Control group (1.7%). No major bleeding occurred in either group. Logistic multiple regression analysis revealed that surgical time extension (OR 1.02, 95% CI 1.00-1.04) was a risk factor of VTE, while administration of LMWH (OR 0.21, 95% CI 0.03-0.99), male sex (OR 0.12, 95% CI 0.01-0.60), and early cancer (OR 0.17, 95% CI 0.02-0.82) reduced the risk of VTE. CONCLUSIONS: Postoperative LMWH administration is safe. The additional effect of LMWH administration on the physical therapy was not statistically proven in this study. However, it could be useful for the patients with risk factors such as female sex, long operation time, and higher cancer stage.

OBJECTIVES: Non-motor symptoms (NMSs) negatively impact the health-related quality of life (HrQOL) of patients with Parkinson's disease (PD). The Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) is a comprehensive scale for evaluating PD. It remains unclear whether the NMSs evaluated with MDS-UPDRS are predictive of HrQOL. This study aimed to investigate whether NMSs, as evaluated with the MDS-UPDRS, could predict the HrQOL of patients with PD. MATERIALS AND METHODS: We conducted a 2-year retrospective observational cohort study assessing 108 patients with PD who were recruited from a single tertiary center between January 2015 and December 2017. MDS-UPDRS was used to assess NMSs and motor symptoms and Parkinson's Disease Questionnaire-39 (PDQ-39) to measure patients' HrQOL. RESULTS: The median age of patients was 69 years, and 65.7% were female. The median MDS-UPDRS part I, part II, part III, and PDQ-39-summary index scores were 8, 10, 22, and 25, respectively. The final stepwise multiple linear regression model showed that female sex (standard partial regression coefficient ß = 0.131, P < 0.05) and baseline MDS-UPDRS part I (ß = 0.272, P < 0.01) and part II (ß = 0.571, P < 0.01) scores significantly predicted the PDQ-39-SI scores at the 2-year follow-up. CONCLUSIONS: In addition to motor symptoms, NMSs at the 2-year follow-up may be useful for predicting the HrQOL of patients with PD. In clinical practice, MDS-UPDRS-guided assessment and treatment of motor symptoms and NMSs may contribute to improving HrQOL in patients with PD.

A 51-year-old Japanese woman was admitted to our hospital because of speech difficulty following severe headache. Neurological examination showed dysarthria and tongue weakness on the right side, indicating right hypoglossal nerve palsy. Needle electromyography of the right side of the tongue showed fibrillation potentials. Magnetic resonance angiography and computed tomography angiography revealed a right, persistent, primitive hypoglossal artery (PPHA) that met Lie's diagnostic criteria. Digital subtraction angiography showed an extended PPHA with irregular caliber in the portion running through the right hypoglossal canal. We diagnosed compression neuropathy of the hypoglossal nerve due to PPHA enlargement based on the findings of ipsilateral hypoglossal nerve palsy, fibrillation that indicated peripheral nerve palsy, and the enlarged diameter of the portion of the PPHA running through the right hypoglossal canal. We prescribed antihypertensive therapy. At 1 year after onset, her tongue weakness was alleviated. Clinicians should consider compression neuropathy due to a PPHA as one of the possibilities in the differential diagnosis of hypoglossal nerve palsy.
