What is known and objective The botulinum toxin (BoNT) has been widely used for various conditions associated with pain. Case description Here, we report a case where celiac plexus block (CPB) with BoNT relieved intractable chronic pancreatic pain without complications. CPB was performed at the L1 level under fluoroscopic guidance, and 50 IU BoNT was injected on each side. After 15 weeks, pain was decreased to 0/10 on a visual analogue scale, without opioids or tramadol. What is new and conclusion Our case demonstrates the efficacy of CPB with BoNT in intractable pain due to severe chronic pancreatitis.Background Cigarette smoking is a major risk factor for head and neck squamous cell carcinoma. Still, the effect of cigarette smoke on the molecular level is unclear. The aim of the present study was to investigate the early effects of cigarette smoke on carcinogenesis of head and neck squamous cell carcinoma. Methods Human oral keratinocytes were exposed for 1 week to standardized cigarette smoke extract, and subsequently RT-quantitative PCR array was performed. Protein expression of dysregulated genes was determined by immunohistochemistry in tissue samples of oral squamous cell carcinoma, oral leukoplakia, and tonsil mucosa. Results RT-PCR revealed upregulation of ITGA-2 and MMP-1, whereas TEK receptor tyrosine kinase was downregulated in human oral keratinocytes. ITGA-2 and MMP-1 were significantly overexpressed in tissue samples of oral squamous cell carcinoma in comparison to normal mucosa (P less then .01 in all experiments). Conclusion Upregulation of ITGA-2 and MMP-1 induced by cigarette smoke contributes significantly to oral carcinogenesis.Objective To investigate olfactory dysfunction (OD) in patients with mild coronavirus disease 2019 (COVID-19) through patient-reported outcome questionnaires and objective psychophysical testing. Methods COVID-19 patients with self-reported sudden-onset OD were recruited. Epidemiological and clinical data were collected. Nasal complaints were evaluated with the sinonasal outcome-22. Subjective olfactory and gustatory status was evaluated with the National Health and Nutrition Examination Survey. Objective OD was evaluated using psychophysical tests. selleck inhibitor Results Eighty-six patients completed the study. The most common symptoms were fatigue (72.9%), headache (60.0%), nasal obstruction (58.6%), and postnasal drip (48.6%). Total loss of smell was self-reported by 61.4% of patients. Objective olfactory testings identified 41 anosmic (47.7%), 12 hyposmic (14.0%), and 33 normosmic (38.3%) patients. There was no correlation between the objective test results and subjective reports of nasal obstruction or postnasal drip. Conclusion A significant proportion of COVID-19 patients reporting OD do not have OD on objective testing.As COVID-19 continues to challenge the practice of head and neck oncology, clinicians are forced to make new decisions in the setting of the pandemic that impact the safety of their patients, their institutions, and themselves. The difficulty inherent in these decisions is compounded by potentially serious ramifications to the welfare of patients and health-care staff, amid a scarcity of data on which to base informed choices. This paper explores the risks of COVID-19 incurred while striving to uphold the standard of care in head and neck oncology. The ethical problems are assessed from the perspective of the patient with cancer, health-care provider, and other patients within the health-care system. While no single management algorithm for head and neck cancer can be universally implemented, a detailed examination of these issues is necessary to formulate ethically sound treatment strategies.Background In the face of the COVID-19 pandemic, cancer care has had to adapt rapidly given the Centers for Disease Control and Prevention and the American College of Surgeons (ACS) issuing recommendations to postpone nonurgent surgeries. Methods An institutional multidisciplinary group of Head and Neck Surgical Oncology, Surgical Endocrinology, and Medical Endocrinology devised Surgical Triaging Guidelines for Endocrine Surgery during COVID-19, aligned with phases of care published by the ACS. Results Phases of care with examples of corresponding endocrine cases are outlined. Most cases can be safely postponed with active surveillance, including most differentiated and medullary thyroid cancers. During the most acute phase, all endocrine surgeries are deferred, except thyroid tumors requiring acute airway management. Conclusions These guidelines provide context for endocrine surgery within the spectrum of surgical oncology, with the goal of optimal individualized multidisciplinary patient care and the expectation of significant resource diversion to care for patients with COVID-19.Based on investigations, there exist tight correlations between neurodegenerative diseases' incidence and progression and aberrant protein aggregreferates in nervous tissue. However, the pathology of these diseases is not well known, leading to an inability to find an appropriate therapeutic approach to delay occurrence or slow many neurodegenerative diseases' development. The accessibility of induced pluripotent stem cells (iPSCs) in mimicking the phenotypes of various late-onset neurodegenerative diseases presents a novel strategy for in vitro disease modeling. The iPSCs provide a valuable and well-identified resource to clarify neurodegenerative disease mechanisms, as well as prepare a promising human stem cell platform for drug screening. Undoubtedly, neurodegenerative disease modeling using iPSCs has established innovative opportunities for both mechanistic types of research and recognition of novel disease treatments. Most important, the iPSCs have been considered as a novel autologous cell origin for cell-based therapy of neurodegenerative diseases following differentiation to varied types of neural lineage cells (e.g. GABAergic neurons, dopamine neurons, cortical neurons, and motor neurons). In this review, we summarize iPSC-based disease modeling in neurodegenerative diseases including Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, and Huntington's disease. Moreover, we discuss the efficacy of cell-replacement therapies for neurodegenerative disease.
