INTRODUCTION: The Valsalva maneuver and its modifications have been utilized across several conditions in medicine; however, there have been difficulties in its application. Thus, at the University of Texas Health Science Center in San Antonio, we designed and patented an affordable and accessible device that mimics Valsalva called "Forced Inspiratory Suction and Swallow Tool (FISST). AREAS COVERED: In this review, we discuss the premise for the design of FISST, based on applications of the law of conservation energy, the continuity equation, and Bernoulli's principle. We then detail the mechanism by which FISST stimulates hiccup cessation by increasing negative inspiratory pressure when drinking through the apparatus, causing diaphragmatic contraction and disruption of the hiccup reflex. We then detail the efficacy and future applications of FISST in addressing other pathologies. EXPERT OPINION: FISST has been used to address hiccups by utilizing its reverse-Valsalva effect to increase parasympathetic stimulation by increasing vagal tone. In a prospective study that we conducted on a cohort of 249 hiccup subjects worldwide, this tool achieved 92% effectiveness. Additionally, several cases, including a published case report, have found FISST successful in terminating supraventricular tachycardias (SVT). FISST may be further utilized in diagnosing or addressing various upper airway pathologies and should be explored further.

Aim: Central hiccups following a stroke are a frequent complication, exerting adverse effects on both the stroke condition and the patient's daily life. Existing treatments exhibit limited efficacy and pronounced side effects. Acupuncture has been explored as a supplementary intervention in clinical practice. This study aims to investigate the clinical effectiveness of acupuncture for post-stroke hiccups.Methods: To identify published clinical randomized controlled trials addressing post-stroke hiccups treatment, comprehensive searches were conducted across PubMed, the Cochrane Library, EMBASE, Web of Science, Chinese Biological Medical (CBM), Wanfang Database, and China Science and Technology Journal (VIP). In addition, we scrutinized ClinicalTrials.gov and the Chinese Clinical Trial Registry. Employing Cochrane Handbook 5.1.0 and Review Manager 5.4 software, three authors independently reviewed literature, extracted data, and evaluated study quality. Data analysis was performed using Stata 16.0 and Review Manager 5.4.Results: A total of 18 trials were encompassed in the analysis. In comparison to standard treatment, acupuncture exhibited a significant enhancement in treatment effectiveness (RR: 1.27, 95% CI: 1.21-1.33; P < 0.00001). Notably, Hiccup Symptom Score displayed a considerable decrease (WMD: -1.28, 95% CI: -1.64 to -0.93; P < 0.00001), concurrent with a noteworthy improvement in the quality of life (WMD: 8.470, 95% CI: 7.323-9.617; P < 0.00001). Additionally, the incidence of adverse reactions decreased (RR: 0.45, 95% CI: 0.16-1.25; P = 0.13), and there was a significant reduction in SAS (WMD: -7.23, 95% CI: -8.47 - -5.99; P < 0.00001).Conclusions: Our investigation suggests that acupuncture could prove effective in post-stroke hiccup treatment. Nonetheless, due to concerns about the quality and size of the included studies, conducting higher-quality randomized controlled trials to validate their efficacy is imperative.

Objective: This study is aimed at investigating the clinical efficacy of anisodamine combined with chlorpromazine on intractable hiccups after stroke. Methods: 150 patients admitted to Affiliated Hospital of the Hebei University of Engineering from 2017 to 2021 were selected as the research objects, all of which received the computed tomography (CT) examination. During CT examination, intelligent algorithms were used to segment the images. An unsupervised multilayer image threshold segmentation algorithm was proposed by using Kullback-Leibler (K-L) divergence and the modified particle swarm optimization (MPSO) algorithm. All patients were divided into three groups, with each group of 50 patients. Patients in the control group (group A) took the calcium tablets, vitamin C tablets, and vitamin B1 tablets orally. Patients in the control group (group B) received the acupoint injection of anisodamine, and those in the observation group (group C) received the acupoint injection of anisodamine combined with chlorpromazine. The therapeutic effect and patient satisfaction of the three groups were compared. Results: The two-dimensional (2D) K-L divergence was applied for the multilayer segmentation of images, which was helpful to obtain accurate images. The MPSO algorithm was adopted to reduce the computational complexity. The total efficiency of group C was 98%, that of group B was 56%, and that of group A was 22%. The total efficiency and satisfaction rate of group C were signally better than those of group A and group B (P < 0.05). Conclusion: The combination of 2D K-L divergence and MPSO algorithm could improve the accuracy of multilayer image segmentation and CT imaging. Acupoint injection of anisodamine combined with chlorpromazine had better efficacy than the injection of anisodamine alone for the treatment of intractable hiccups after stroke, with high safety and clinical promotion value.

Recurrent and persistent bouts of hiccups impact the quality of life by interfering with eating, social interaction and work. Popular home remedies, such as breath holding and drinking ice water, target activity in the vagal and phrenic nerves that are thought to trigger these repetitive, myoclonic contractions. However, the pathophysiology of hiccups and the mechanism by which any of these methods work are unclear. Indeed, so little is known that there is no agreement whether the 'Hic' sound is due to the abrupt closure of the epiglottis or the glottis, including the vocal cords.Investigations were performed in a 50-year-old, otherwise healthy male with recurrent hiccups, in whom contractions persisted for up to 4 hours. Hiccups were initiated by drinking carbonated soda. The aerodigestive tract was visualised by video fluoroscopy. Hiccups were terminated by drinking a non-viscous contrast agent through a forced inspiratory suction and swallow tool. This device requires significant suction pressure (-100 mm Hg) to draw fluid into the mouth and is effective in approximately 90% of cases. The images were analysed together with concurrent audio recordings to gain insight into 'what causes the 'hic' in hiccups' and how this commonplace but annoying problem can be treated.

BACKGROUND: Persistent and intractable hiccups are a common clinical symptom that cause considerable physical pain to patients and severely damage their quality of lives. An increasing number of studies have demonstrated that acupuncture applied at acupoints dominated by Cuanzhu (BL2) can be used as one of the nonpharmacological therapies for controlling intractable hiccups. However, there is insufficient evidence evaluating the safety and effectiveness of those interventions. Therefore, this study is intended to conduct a systematic review and meta-analysis to provide evidence for a further study investigating alternative treatment options for persistent and intractable hiccups. METHODS AND ANALYSIS: Randomized controlled trials (RCTs) of adult patients aged >18âyears who meet the criteria for intractable hiccup diagnosis will be included, regardless of gender, nationality, and education level. Eight electronic databases will be searched, including 4 Chinese databases (CNKI, SinoMed, Wanfang Database, and Chinese Scientific Journal Database), 4 English databases (Web of Science, Medline, Embase, and Cochrane Library), from their date of establishment to September 2020. Two independent reviewers will evaluate the title summary for each RCT. Disagreements will be discussed with a third commentator. Data integration, heterogeneity analysis, subgroup analysis, and sensitivity analysis, will be performed using R-3.3.2 software. The RevMan 5.3 software will be used for the meta-analysis, and the "risk of bias" assessment will be conducted based on the methodological quality of the included trials recommended by the Cochrane Handbook 5.1. The quality evaluation of this study will be completed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). RESULTS: This study will summarize all the selected trials aimed at estimating the effectiveness, as well as safety, of applying acupuncture at acupoints dominated by Cuanzhu (BL2) to persistent and intractable hiccups. CONCLUSIONS: This systematic review will provide evidence to assess the validity and safety of applying acupuncture at acupoints dominated by Cuanzhu (BL2) for persistent and intractable hiccups, which may provide clinicians with more choices in the treatment of this disease.

Persimmon Calyx is a crude drug derived from the persistent calyx of mature fruit of Diospyros kaki Thunberg (Ebenaceae) and is used for the treatment of intractable hiccups. Although there are several reports on the isolation of constituents from Persimmon Calyx, its active constituents have not been elucidated. In this study, by focusing on the medicinal part of Persimmon Calyx, calyx on mature fruit of D. kaki, we examined the changes in the extraction amounts of 3 cultivars of D. kaki ('Hiratanenashi', 'Jiro', and 'Tonewase') to identify and quantify seasonally variable constituents during the maturation process by analysing their chemical compositions. We found that the extraction weight of the calyx, fruit of persimmons, and total tannin content in calyxes were significantly increased during maturation. Lupeol (1), betulinic acid (2), pomolic acid (3), ursolic acid (4), ß-sitosterol (5), rotungenic acid (6), barbinervic acid (7), catechin (8), gallocatechin (9), and sucrose (10) were identified in the calyx of D. kaki. Compounds 1, 6, and 7 were isolated from Persimmon Calyx for the first time. Moreover, the isolated compounds (1-7) and their analogue (oleanolic acid) were quantitatively analysed, and the results showed that the amounts of 4 and oleanolic acid were reduced during maturation, whereas that of 2, 3, 6, and 7 were increased.

BACKGROUND: Hiccups are involuntary contractions of the diaphragm and intercostal muscles, which lead to sudden contractions of the glottis. CAM, such as acupuncture is commonly used and stimulation of the vagus nerve and interference with phrenic nerve conduction are also used to treat hiccups. However, there is little evidence on the effectiveness of acupuncture for cancer-related hiccups. We will plan to conduct a systematic review and meta-analysis of RCTs to evaluate the current evidence on the effects of acupuncture for cancer-related hiccups. METHOD: The following databases will be searched: PubMed, the Cochrane Library, Wanfang Data, China National Knowledge Infrastructure (CNKI), SinoMed, VIP, Medline, Embase, and EI. Randomized controlled trials will be included to evaluate the effect and safety of acupuncture on cancer patients with hiccups. We will set standards for the curative effect on the basis of the standard of cure and improvement for clinical disease diagnoses. The risk of bias will be assessed by the Cochrane risk of bias tool. We will conduct a meta-analysis and sensitivity analysis, as well as a subgroup analysis if high heterogeneity is present, using Revman 5.3. We will use funnel plots to identify potential reporting biases. We will test asymmetry using Egger test. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) will be used to evaluate the quality of evidence. RESULTS: This study will be to assess the effect and safety of acupuncture for cancer-related hiccups. CONCLUSIONS: This study will assess the effect of acupuncture for cancer-related hiccups and provide reliable evidence for the choice of treatments.

RATIONALE: Hiccups are a common clinical symptom, and persistent hiccups and intractable hiccups severely impair the individual's quality of life. To date, there has been no effective treatment specifically for hiccups. Herein, we report 2 cases with intractable or persistent hiccups that were successfully treated with extracranial acupuncture. PATIENT CONCERNS: The first case is a 46-year-old woman who presented with a 7-year history of intractable hiccups that had worsened over the past 3 years. She also complained of chest tightness, dyspnea, palpitations, dreaminess, dysphoria, intolerance of cold, and hypohidrosis. The second case is a 75-year-old man who presented with a 7-day history of persistent hiccups and hematemesis for 3âhours. The patient's persistent hiccups were treated using traditional Chinese acupuncture, but the patient reported no remarkable benefit. DIAGNOSES: They were diagnosed as intractable or persistent hiccups. INTERVENTIONS: They were treated with extracranial acupuncture. OUTCOMES: The hiccups completely disappeared. During the follow-up period, the hiccups did not reappear. LESSONS: According to neural balance theory, an episode of the hiccups is caused by an imbalance of the nervous system. Extracranial acupuncture in the area adjacent to the external occipital protuberance affects the intracranial nervous system, which can effectively control the hiccups. Our study provides a new approach to the treatment of hiccups.

BACKGROUND: Persistent and intractable hiccups bring serious inconvenience to patients' work and daily life, and impair their quality of life. Relevant studies showed that acupuncture therapy might be effective in treating persistent and intractable hiccups. However, there is no consistent conclusion so far. The aim of our research is to investigate the safeties and effectiveness of acupuncture in treating patients with persistent and intractable hiccups. METHODS: We will search randomized controlled trials (RCTs) using acupuncture therapy to treat persistent and intractable hiccups in the following 6 English electronic databases and 3 Chinese electronic databases: MEDLINE, EMBASE, the Cochrane Library, Web of Science, PsycINFO, Allied and Alternative Medicine (AMED), Chinese National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP) and Wanfang data. The cure rate and the total effective rate will be considered as the primary outcomes. Complete cessation within a given period post-treatment of hiccups, changes in frequency or intensity of hiccups, concomitant symptom score, and adverse events will be considered as secondary outcomes. We will use Endnote software 9.1 for studies selection, Review Manager software 5.3, and STATA 13.0 software for analysis and synthesis. RESULTS: we will synthesize current studies to evaluate the the safeties and effectiveness of acupuncture for persistent and intractable hiccups. CONCLUSION: Our study will provide evidence of acupuncture therapy for persistent and intractable hiccups.

OBJECTIVE: To explore the rule of acupoint combination in acupuncture treatment of hiccups. METHODS: Original research articles on acupuncture treatment of hiccup were collected from databases of CNKI, Wanfang, VIP, and Pubmed by using key words of "hiccup", "acupuncture" "diaphragmatic spasm" "body acupuncture" "filiform needle" and "electroacupuncture". According to our inclusive and exclusive criteria, the collected data were extracted to establish an acupuncture prescription database for hiccup. Then, the regularities of acupoint combinations for hiccup were analyzed by using Gephi complex network analysis software. RESULTS: ;A total of 606 articles containing 634 acupoint prescriptions for acupuncture treatment of hiccups were brought into analysis. There were 133 single-acupoint prescriptions (20.98%), which was significantly lower than the multi-acupoint prescription (501, accounting for 79.02%). There were mainly acupoints in multi-acupoint prescriptions, and distal-proximal acupoint combination method were often used as the basis of acupoint selection (326, accounting for 65.07%). A total of 163 acupoints were involved, with a total frequency of 2 969. Among them, Neiguan(PC6) was used most frequently (400 times, accounting for 13.47%), followed by Zusanli (ST36), Zhongwan (CV12), Danzhong (CV17), and Taichong (LR3). The acupoints of the Conceptional Vessel(666 times, accounting for 22.43%), and Stomach Meridian, Pericardium Meridian and Liver Meridian were chiefly used. There were 67 specific acupoints, the frequency of use was 2 555 times(accounting for 86.05% of the total frequency), among which the frequency of the five Shu-points was the highest (875 times, accounting for 29.47% of the total frequency), and followed by eight confluence points. CONCLUSION: ;The core acupoints are PC6, ST36, CV12, etc. and the distal-proximal acupoint combination method found in this study are often used as the basis of acupoint selection and acupoint prescription for acupuncture treatment of hiccup.

Hiccups are occasionally experienced by most individuals, and although not life-threatening, they may leadto a decline in quality of life. Shitei extract(shitei, persimmon calyx)may be usedfor the treatment of hiccups. The effects of shitei extract were investigatedin patients admittedto the Japanese RedCross Musashino Hospital between October 2011 andM ay 2016. Numerous prescriptions for shitei extract were reportedin the Department of Respiratory Organs andNeurosurgery. The primary causes of hiccups were chemotherapy andbrain disease. Of 149 patients, 107(71.8%)sufferedfrom hiccups. None of the patients reported adverse events related to the administration of shitei extract. The incidence of hiccups was significantly higher in patients with brain disease(p=0.0075), treatedwith chemotherapy for cancer(p=0.0402), or requiring the insertion of a gastric tube(p=0.0065). Among those treatedwith chemotherapy for cancer, shitei extract was effective against hiccups in 82.0% patients(45 of 55). Furthermore, four patients receivedprophylaxis with shitei extract for the prevention of hiccups after chemotherapy. In conclusion, these results indicate that shitei extract is an effective and safe therapeutic drug for the treatment of hiccups. In particular, shitei extract was effective in the prevention of hiccups after chemotherapy.

Percutaneous endoscopic gastrostomy (PEG) is an established practice for long-term nutrition in dysphagia-suffering stroke patients. This study sought to determine the feasibility and safety of outpatient, unsedated PEG implementation in stroke patients. This retrospective cohort study involved stroke victims who underwent unsedated outpatient PEG insertion from 2014 to 2017 at our Surgical Endoscopy Unit. Patients were given pharyngeal anesthesia with lidocaine 10% spray, while the PEG tube was placed under local anesthesia. The incidence of intraprocedural and postprocedural complications and 30-day mortality rate were recorded. Data from 127 cases were analyzed. The procedures were performed with minor, transient complications, which resolved after rescue maneuvers. No intraprocedural and postprocedural major complications or death were observed. During the 30-day follow-up, the most important complication involved a single case of accidental PEG removal that was successfully resolved surgically. Unsedated PEG insertion appears to be a feasible, well-tolerated, and safe option for stroke-related dysphagia.

OBJECTIVE: There are multiple treatment options for hiccups, including non-pharmacological therapies, but little evidence of superiority of one treatment over another. The aim of this study was to investigate the effects of acupuncture on persistent hiccups after arthroplasty. METHODS: From April 2010 to December 2015, 15 patients with primary unilateral total hip/knee arthroplasty were diagnosed with persistent hiccups and given acupuncture at PC6, CV12 and ST36. Each acupuncture session lasted 30 min. The total number of treatment sessions was determined by the persistence of symptoms, but acupuncture was administered no more than three times over the course of a week. The hiccups assessment instrument (HAI) was used to assess the severity of hiccups pre-treatment and post-treatment. Adverse events were also recorded. RESULTS: Absolute resolution was observed in all 15 patients after less than three acupuncture sessions. Of these, 10 patients required only one acupuncture session, 3 patients required two sessions and 2 patients required three sessions. The HAI score improved after each round of acupuncture treatment (P<0.05). The average HAI score improved significantly post-acupuncture compared to baseline values pre-treatment (P<0.05). Symptoms accompanying the hiccups included pain in the diaphragmatic area (five patients), mild dyspnoea (three patients), dysphagia (two patients) and nausea/vomiting (one patient). All these accompanying symptoms disappeared at the point of resolution of the hiccups. There were no adverse effects related to acupuncture during the study period. CONCLUSION: Based on our results, acupuncture may represent a potential treatment option for hiccups after arthroplasty. Caution must be exercised, however, given the lack of a control group. Accordingly, randomised controlled trials will be required to verify the efficacy and effectiveness of acupuncture for the treatment of hiccups.

Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively (P<0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

OBJECTIVES: To assess the effectiveness and safety of acupuncture for hiccups following stroke. METHODS: Medline, Embase, CENTRAL, CINAHL, and four Chinese medical databases were searched from their inception to 1 June 2015. The dataset included randomised controlled trials (RCTs) with no language restrictions that compared acupuncture as an adjunct to medical treatment (effectiveness) or acupuncture versus medical treatment (comparative effectiveness) in stroke patients with hiccups. The Cochrane risk of bias tool was used to assess the methodological quality of the trials. RESULTS: Out of 436 potentially relevant studies, five met the inclusion criteria. When acupuncture was compared with other interventions (as sole or adjunctive treatment), meta-analysis revealed a significant difference in favour of cessation of hiccups within a specified time period (CHWST) following intervention when used as an adjunct (risk ratio (RR) 1.59, 95% CI 1.16 to 2.19, I2=0%), but not when used alone (RR 1.40, 95% CI 0.79 to 2.47, I2=65%, ie, high heterogeneity). No safety information was reported in these studies. CONCLUSIONS: Our systematic review and meta-analysis suggests that acupuncture may be an effective treatment for patients suffering from hiccups following stroke when used as an adjunct to medical treatment. However, due to the limited number of RCTs and poor methodology quality, we cannot reach a definitive conclusion, hence further large, rigorously designed trials are needed.

INTRODUCTION: Hiccup crises are generally benign and self-limiting, but longer episodes affect quality of life and must be treated. There are recognisable causes that otorhinolaryngologists must know and be aware for diagnosis and therapeutic alternatives. The main expression is a spasmodic glottic noise with characteristic neck alterations. PATIENTS AND METHODS: This was a retrospective study from 1979 with patients suffering persistent or recurrent hiccups. Chronobiology, comorbidity, findings from explorations, therapies and outcomes were noted. Thirty-seven patients were studied (mean age, 45.5±13.5 years; 30 males), with persistent hiccups in 23 (62%). RESULTS: A potential associated aetiology was observed in 24 cases (65%): oesophageal disorders -mainly gastroesophageal reflux- were detected in 14 cases and concomitant oncological disease was found in 8. Only 3 cases were admitted for surgery due to these findings. Therapeutic strategies with metoclopramide were used in 18 subjects, chlorpromazine in 17 and baclofen in 13, while carbamazepine or haloperidol were used in a minority. Phrenic nerve stimulation was employed in 6 patients. Hiccups disappeared in 32 cases. Out of 22 cases for which follow-up was possible, the hiccups recurred in 5 subjects (the subjects requiring new therapies) and 11 patients died. CONCLUSIONS: Chronic hiccup represents a multidisciplinary challenge that includes potential head and neck affection, a diagnostic schedule for ruling out causes, frequent base oesophageal alterations and high incidence of malignant neoplasm. Prokinetic and neuroleptic agents with antidopaminergic and anticholinergic effects are the pillars of its treatment.
