Small intestinal bacterial overgrowth (SIBO) is a bowel disorder prevalent among patients with Parkinson's disease; SIBO treatment has been shown to modulate neurological inflammation, motor and cognitive outcomes there. However, to date, no link between Alzheimer's dementia and SIBO has been established. This pilot study sought to estimate the prevalence of SIBO in Alzheimer's dementia in the outpatient setting in Singapore General Hospital. It entailed performing a hydrogen breath test and objectively scoring gastrointestinal symptoms and their severity in 48 patients, comparing symptom scores and mean breath test values in those with mild to moderate Alzheimer's against age- and sex-matched controls that did not fulfill DSM-V criteria for probable Alzheimer's. Here, the prevalence of positive breath tests and symptoms of SIBO were no greater among Alzheimer's patients than in controls. This suggests that the gut microbiome changes and increased bowel inflammation seen in previous studies on Alzheimer's patients are likely effected through pathways other than SIBO, and are likely more complex than a mere increase in small bowel bacterial volume. Rather, future research could be directed along the lines of qualitative changes in small bowel microbiota, or pathologies in other parts of the gastrointestinal tract such as the colon or stomach, aspects which are not adequately captured by the hydrogen breath test.

The time window of IVT with recombinant tissue plasminogen activator (rt-PA) has been extended from post-stroke 3 to 4.5 hours. In patients with cerebral penumbra identified using cerebral perfusion imaging, IVT is still beneficial within 4.5 to 9 hours after onset of stroke. For those without clear stroke onset time, DWI-FLAIR mismatch by brain MRI indicates hyperacute infarct and IVT is indicative. For patients with large cerebral vessel occlusion, endovascular thrombectomy (EVT) alone is likely non-inferior to bridging therapy (IVT followed by EVT) and this issue is still under investigation. Serial studies have provided the evidence of safety and risk of IVT in specific groups of patients, such as elderly, anticoagulant users, and those having cerebral microbleeds or seizure. Tenecteplase has higher fibrin selectivity than rt-PA and large clinical trials have demonstrated its great potential for stroke therapy.

She underwent whole body multi-detector computed tomographic (MD-CT) to evaluate possible lytic bone lesions. MD-CT showed small, multiple osteolytic lesions, particularly at the skull level (Figure 1, 2). MM is a plasma cell disorder. It is characterized by the monoclonal proliferation of malignant plasma cells (1,2). These cells, among their various characteristics, determine an infiltrate haemopoietic locations (1). Pathogenesis of MM related bone disease is the uncoupling of the bone remodelling process. There is an increased activity of osteoclastogenesis with the suppressed osteoblastic one, resulting in bone loss (1- 3). This process creates lytic lesions without reactive bone formation (2). Bone disease could be from single lytic lesion to multiple lytic lesions affecting any part of skeleton, preferably skull, spine and long bones (3). MD-CT, with dedicated low-dose protocols, is able to provide whole body skeletal volume information with a greater sensitivity than conventional X-ray studies in MM patients (3). Whole body CT with lowdose protocols can detect lesions with less than 5% trabecular bone destruction, and it is the first-line diagnostic imaging procedure for the diagnosis of lytic bone disease in patients affected by MM (4). When skull is involved, its most common MD-CT presentation is by numerous, well-circumscribed and punched-out lytic bone lesions, without reactive bone formation and diffuse osteopenia (1-5), as in the case presented.</p>","PeriodicalId":7102,"journal":{"name":"Acta neurologica Taiwanica","volume":" ","pages":"81-82"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39440083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
