Numerous studies have confirmed a positive correlation between premature tooth loss, reduction in masticatory function and significant cognitive decline observed through learning disabilities, including overcoming ordinary life problems to early and advanced forms of dementia. Reduced numbers of teeth in the main food processing area, i.e., loss of large molars, have been implicated as a possible cause of cognitive impairment. In research in this area, some groups of major etiopathogenetic causes of this issue have also been established. A significant etiopathogenetic cause of tooth loss is the disappearance of their mechanoreceptors in the periodontium, causing the disappearance of sensorimotor excitation via the cranial nerve V and the associated atrophic changes in the trigeminal brain nuclei and their branching in the Locus Coeruleus area. It may cause further neurodegenerative involvement in this area, one of the centers of the adrenergic system involved in cognitive function. Relatively well-studied factors are the lack of blood supply to the cerebral area during inadequate mastication caused by loss of molars and the consequent hypoxia of brain and nerve structures. In the research and development of Alzheimer's disease, there have been many recent references to the fact that the primary bacterium causing periodontitis, Porphyromonas gingivalis, can infect the neurons of the cranial nerve V ending close to the Locus Coeruleus and thus tau proteins, after tooth extractions, can spread to other subcortical nuclei in the brain. These findings are of great relevance to clinical practice in dentistry as we strive to prevent tooth loss in the distal compartment, which is made possible by the tremendous expansion of endodontic techniques and technologies to save de facto every tooth and its periodontium with the mechanoreceptors necessary to preserve sensorimotor nerve excitability and sensorimotor nerve networks. We uncompromisingly eliminate every periodontal infection in the subgingival region as part of our preventive-therapeutical procedures.</p>","PeriodicalId":94154,"journal":{"name":"Neuro endocrinology letters","volume":"45 7-8","pages":"468-474"},"PeriodicalIF":0.0,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142908149","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}

We diagnosed pheochromocytoma and performed a right adrenalectomy in September 2021. Postoperatively, the patient's palpitations disappeared and his laboratory findings normalized. Glucose intolerance is well known to occur before surgery in patients with pheochromocytoma, but it is extremely rare that hypoglycemia is indicated by a presurgery OGTT, as in our patient's case. Only three similar cases are reported to date, and in all three, hypoglycemia occurred ≥2 hr after loading, accompanied by excessive insulin secretion compared to the plasma glucose level. Our patient's case is the only one in which preload hyperglycemia was observed. Before his OGTT, he had run from the train station to the hospital, which was likely to be the cause of the preload hyperglycemia.
