We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy between the Tc-99m TRODAT-1 and Tc-99m ECD scan provides insight into the imbalance between direct and indirect circuits along the nigrostriatal pathway, as the fundamental genesis of HGHC. Furthermore, the hyperperfusion at the left thalamus represents thalamic disinhibition secondary to loss of pallidal negative control, which ultimately leads to HGHC through re-entrant outflow to the motor cortex.

OBJECTIVEAccuracy of diagnostic methods for detecting Helicobacter pylori (H. pylori) infection among patients with bleeding peptic ulcers has not been thoroughly investigated. The aim of this study was to compare the diagnostic tests and their combined usage in detection of H. pylori infection in patients with bleeding gastric ulcers and without the use of nonsteroidal anti-inflammatory drugs.

METHODSA total of 57 patients who presented with bleeding gastric ulcers by endoscopy were enrolled. The status of H. pylori was identified by performing the rapid urease test (RUT), histology and (13)C-labeled urea breath test (UBT). The criteria for having H. pylori infection was a minimum of two positive tests.

RESULTSThe prevalence of H. pylori infection in our patient group was 80.7%. Among the three tests used: RUT, histology, and UBT, sensitivities were 56.5%, 97.8% and 100%, while specificities were 100%, 45.5% and 81.8%, respectively. The overall accuracies of the tests were 78.3%, 71.6% and 90.9%, respectively. Although UBT obtained significantly higher accuracy than histology (P = 0.02) as opposed to RUT (P = 0.11), UBT had significantly higher sensitivity than RUT (P < 0.001). In terms of combining any two of the three tests, more accuracy (98.9%) was achieved when both UBT and histology were used to confirm the diagnosis of the other. Conversely, failure to use combined tests generated the potential of missing a proper H. pylori diagnosis.

CONCLUSIONSUBT is superior to the other two tests in bleeding gastric ulcers. RUT lacks sensitivity for detection of H. pylori infection. However, the concomitant use of UBT and histology seems to be more accurate when gastric ulcers present with bleeding.

Background: Compared with the Western population, central demyelinating disorders are relatively rare while the data on the prognostic value of autoantibodies together with clinical characteristics and cognitive dysfunction has rarely been explored in neuromyelitis optica (NMO) and multiple sclerosis (MS). Methods: Nineteen patients with MS and 14 with NMO underwent clinical profiling and cognitive assessment. According to serology tests, they are divided into four subgroups for further analysis. Results: There was higher frequency of aquaporin-4 immunoglobulin G. sero-positivity (64.3% vs. 10.5%; p=0.003) and antinuclear antibodies (ANA) and/or antibodies to extractable nuclear antigens (anti-ENA) in NMO compared to MS (42.9% vs. 5.2%; p=0.026). The presence of anti-ENA represented a unique clinical phenotype, with longer segment of myelitis (p=0.049), female preponderance, and an inverse correlation between age-of-onset and annual relapse rate (ρ= -0.88, p=0.021). Among patients with anti-ENA positivity, comprehensive serology panels revealed Sjögren’s syndrome A antibodies as the most common (83%), in contrast to limited clinical documentation of Sjögren’s syndrome (16%). There was no significant difference in cognitive assessment by anti-ENA status. MS and NMO represent two different serologic entities. Conclusions: Anti-ENA may have prognostic value for its linkage to a unique clinical phenotype, which has longer initial segment of myelitis, female preponderance, and higher annual relapse rate on earlier age-of-onset, but has limited clinical impact on cognition. Further studies are warranted to investigate whether anti-ENA represents an epiphenomenon of myelitis or simply a systemic inflammatory state.

Background:Reports on the aquaporin-4 immunoglobulin G (AQP4-IgG) status for cognitive performance and neuroimaging correlations are limited in neuromyelitis optica (NMO) and multiple sclerosis (MS) literature. Methods: Cognitive results of 19 MS and 15 NMO patients were compared with 47 agematched controls. Apparent diffusion coeffi cient (ADC) values were used to delineate gray matter and white matter damages and correlate with neuropsychological results. Results: Verbal memory test showed signifi cant differences between MS and NMO in the late registration, early and delay recall (p<0.05), while their retention rates were even. In MS, ADC values were signifi cantly elevated in the dorsolateral prefrontal and occipital gray matter which was in contrast with NMO group that showed elevation in the dorsolateral prefrontal gray matter and parieto-occcipital white matter. AQP4-IgG status exerted a limited effect on ADC values and neuropsychological results. Conclusions: Verbal memory test might be helpful in differentiating NMO and MS. ADC values can be used as a surrogate marker for tissue injury in NMO and MS since they were in line with the cognition scores. Anatomical regions with elevated ADC values were different in NMO and MS.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.
