Refractory singultus and area postrema syndrome as a presentation of neurocysticercosis.

Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system, caused by the pork tapeworm, Taenia solium Common presenting features are seizures, headaches and focal neurodeficits. The present report details the anecdote of a middle-aged Asian man, who presented with subacute onset of persistent nausea, vomiting and hiccups. Following unsuccessful trials with numerous prokinetic, antipsychotic, muscle relaxant and anticonvulsant medications, as well as an uneventful battery of gastrointestinal tests, he was referred for neurological evaluation. The constellation of symptoms was congruent with the diagnosis of area postrema syndrome. Although initial CT scan of brain was normal, MRI with contrast evaluation revealed a circumscribed, ring-enhancing lesion of the dorsal medulla oblongata, reminiscent of colloid vesicular stage of NCC. The patient was successfully treated with steroids and albendazole. The association of refractory singultus, nausea and vomiting and NCC is thus far, not reported in the literature.

Persistent hiccups after acute COVID-19 successfully treated with chlorpromazine: a case report.

INTRODUCTION: Hiccups are among the rare complications of COVID-19 infections. There are several published reports of persistent hiccups presenting during the acute COVID-19 period. However, there are very few published reports of persistent hiccups occurring in the post-acute COVID-19 period. Consequently, most clinicians may not be aware of this rare presentation. This case highlights an atypical presentation of persistent hiccups that manifested during the post-acute COVID -19 period that clinicians need to be aware of. The caseadds to the ever increasing body of knowledge about symptoms and signs associated with Severe Acute Respiratory Syndrome Corona Virus type 2 (SARS CoV-2) infection. CASE PRESENTATION: A 27 year old male black Zambian patient presented to the emergency department of our hospital with persistent hiccup, 35 days after the initial acute episode of COVID-19. This was associated with breathlessness. There were no other symptoms. He had no history of pulmonary, gastrointestinal, neurological disease or malignancy. He did not take any alcohol or smoke. He had never used any recreational drugs. He was employed as a monitoring and evaluation officer at one of the main COVID centres in the capital. On examination, the patient was anxious. Blood pressure was 141/82, pulse rate was 95 beats per minute, respiratory rate was 26 breaths per minute, temperature was 36.8C and oxygen saturation was 97% on room air. Systemic examination was normal. Chest X-ray and abdominal ultrasonography were normal. A rapid COVID-19 antigen test, and COVID-19 Polymerase Chain Reaction (PCR) test that were done the following day were negative. All other haematological and biochemical tests, including D-dimer and C-reactive protein (CRP), were also normal. A diagnosis of post-acute COVID-19 associated hiccups was made. The patient responded well to treatment with chlorpromazine 25 mg 8 hourly. The hiccups disappeared completely after the fourth dose of chlorpromazine. CONCLUSION: This is one of the few published cases of COVID-19 associated persistent hiccups, occurring more than a month after the initial presentation. Most of the published cases report hiccups occurring in the acute COVID-19 period. Consequently, hiccups occurring in the post-acute COVID-19 period may not be attributable to COVID-19. This case has highlighted the need to consider post-acute COVID-19 in the differential diagnosis of persistent hiccup.

Intractable cough and hiccups after resuscitation and acute coronary syndrome treatment successfully treated using the Kampo medicine bukuyoingohangekobokuto: A case report.

BACKGROUND: Even in patients who survive resuscitation through multidisciplinary treatment, minor persistent symptoms can make hospital discharge difficult. Herein, we report a case of myocardial infarction with intractable symptoms following resuscitation, which were successfully treated using Kampo medicine. CASE PRESENTATION: A 71-year-old man experienced intractable cough and hiccups following resuscitation for acute myocardial infarction. Despite successful invasive treatment for his cardiac condition, the patient's persistent symptoms hindered his recovery and discharge from hospital. The patient was diagnosed with qi and blood deficiency, qi stagnation, and fluid retention, before being prescribed the Kampo medicine "bukuryoingohangekobokuto (BRIHK)". Within days of treatment initiation, his symptoms notably improved, allowing him to be discharged. CONCLUSION: This case highlights the potential of Kampo medicine for addressing post-resuscitation symptoms that are refractory to conventional treatments, and emphasizes the importance of integrating Kampo medicine with Western medical practices to enhance patient care and quality of life.

Prolonged hiccups induced by renal infarction: a case report.

BACKGROUND: Hiccups are common symptoms that last for less than 48 hours. However, we encountered a case of renal infarction in a patient with prolonged hiccup. The relationship between hiccups and renal infarction is important in differentiating patients with prolonged hiccups. CASE PRESENTATION: An 87-year-old Japanese man with atrial fibrillation and receiving antithrombotic therapy presented to the emergency department with prolonged hiccups. The patient discontinued antithrombotic therapy for atrial fibrillation due to subcortical bleeding, after which he experienced right back pain. He was diagnosed with right renal infarction based on computed tomography images, and the antithrombotic therapy was continued. The patient's hiccups ceased, and he was discharged on hospital day 11. CONCLUSION: Hiccups can be induced by various clinical conditions. It is hypothesized that the inflammation of the right kidney infarction stimulated the diaphragm and induced prolonged hiccups in this patient; this theory is supported by the computed tomography images. This case report shows that internal organ diseases irritating the diaphragm can cause hiccups, and renal disease should be considered in patients with prolonged hiccups.

Rare case report of moxifloxacin-induced persistent hiccups.

Moxifloxacin is a broad-spectrum antimicrobial agent that is commonly used in clinical practice. Here we report an unusual case of a patient with persistent hiccups caused by moxifloxacin. A man aged in his 40s was treated with moxifloxacin for tuberculous pleurisy. Hiccups occurred 2 hours after intravenous injection of moxifloxacin and lasted into evening. On the second day after injection, hiccups occurred again and made it difficult for him to fall asleep. The clinician ruled out gastrointestinal disease, nervous system disease, electrolyte disturbance and other factors. On assessing causality of the adverse drug reaction, the Naranjo scale for moxifloxacin was six, indicating a probable relationship of hiccups with moxifloxacin. Hiccups stopped 2 min after intramuscular injection of metoclopramide. To our knowledge, this is the first case report about moxifloxacin-induced persistent hiccups. Clinicians should be aware of the rare adverse reaction.

Baclofen for hiccups: a large mixed methods multisite study.

OBJECTIVE: Hiccups can be bothersome and spawn morbidity. Although oral baclofen is perhaps the most prescribed agent for hiccups, a paucity of data supports its use. METHODS: This multisite, single institution study examined the medical records of patients who had hiccups and had been prescribed baclofenas noted in a clinical encounter. Mixed methods were used to assess baclofen's palliative efficacy. In view of the sometimes transient nature of hiccups and other such factors, cessation or palliation of hiccups in 75% of patients was sought to indicate true palliation. RESULTS: A total of 301 patients with a median age of 61 years (range 20-87 years) and a male predominance are the focus of this report. Baclofen was most often prescribed at 10 mg orally three times a day. Only 105 patients (35%) (95% CI: 30% to 41%) acquired hiccup palliation. Corroborative medical record quotations included, 'Still has hiccups.'Quotations such as, 'Responding to baclofen this AM', were also recorded. Baclofen appeared more likely to benefit patients with hiccups of >48 hours (chronic) duration in univariable analyses (OR for benefit: 0.51 (95% CI: 0.29 to 0.91; p=0.02) with similar conclusions drawn from multivariable analyses. Adverse events occurred in 15 patients with drowsiness the most common. CONCLUSIONS: Baclofen did not meet this study's a priori threshold for successful hiccup palliation, but further study is indicated to learn whether baclofen might help patients with chronic hiccups.

Successful termination of persistent hiccups via combined ultrasound and nerve stimulator-guided singular phrenic nerve block: a case report and literature review.

Persistent hiccups that occur after abdominal surgery seriously affect postoperative rehabilitation. Phrenic nerve block therapy has been recommended after failure of medication or physical maneuvers. However, the phrenic nerve is often difficult to accurately identify because of its small diameter and anatomic variations. We combined ultrasound with the use of a nerve stimulator to quickly and accurately identify and block the phrenic nerve in a patient with postoperative persistent hiccups. The ongoing hiccups were immediately terminated with no adverse effects. The patient reported no recurrence during the 2-week follow-up period. We conclude that the combined use of real-time ultrasound guidance and a nerve stimulator for singular phrenic nerve block might be an effective intervention for terminating postoperative persistent hiccups, although further studies are needed to evaluate the safety and efficacy of this technique. The findings in this case suggest a potential clinical application for this technique in managing persistent hiccups, thereby contributing to improved patient care and outcomes.

Ultrasound-guided bilateral pulsed radiofrequency of the phrenic nerve for prolonged hiccups: a case report.

Singultus is the sudden onset of erratic diaphragmatic and intercostal muscle contraction immediately followed by laryngeal closure. Pathophysiology involves afferent, central and efferent components. Bilateral phrenic nerve block was performed to a 46-year-old woman with a brain tumor with persistent hiccups, with initially positive response but later symptom recurrence. Bilateral pulsed radiofrequency of the phrenic nerve was performed guided by ultrasonography (US). In the follow-up, absence of hiccups was confirmed. The patient was discharged 24 h later. Persistent or untreatable singultus is an infrequent condition that should not be dismissed. This approach is a safe, accurate and effective therapeutic approach for patient's refractory to conservative treatment. Further studies are needed to establish safety and effectiveness of the treatment.

What percentage of patients with cancer develop hiccups with oxaliplatin- or cisplatin-based chemotherapy? a compilation of patient-reported outcomes.

BACKGROUND: Chemotherapy-induced hiccups are understudied but can cause sleep deprivation, fatigue, pain in the chest and abdomen, poor oral intake, aspiration, and even death. As a critical next step toward investigating better palliative methods, this study reported patient-reported incidence of hiccups after oxaliplatin- or cisplatin-based chemotherapy. METHODS: The current study relied on 2 previous studies that sought to acquire consecutive direct patient report of hiccups among patients who had recently received chemotherapy with cisplatin or oxaliplatin. These patient-reported data in conjunction with information from the medical record are the focus of this report. RESULTS: Of 541 patients, 337 were successful contacted by phone; and 95 (28%; 95% CI: 23%, 33%) of these contacted patients reported hiccups. In univariable analyses, male gender (odds ratio (OR): 2.17 (95% confidence ratio (95% CI): 1.30, 3.62); p = 0.002), increased height (OR: 1.03 (95% CI: 1.00, 1.06); p = 0.02), and concomitant aprepitant/fosaprepitant (OR: 2.23 (95% CI: 1.31, 3.78); p = 0.002) were associated with hiccups. In multivariable analyses, these statistically significant associations persisted except for height. CONCLUSIONS: These patient-reported data demonstrate that oxaliplatin- or cisplatin-induced hiccups occur in a notable proportion of patients with cancer. Male gender and concomitant aprepitant/fosaprepitant appear to increase risk.

Hiccups: An atypical side effect experienced during chemo-radiotherapy in carcinoma nasopharynx.

ABSTRACT: Nasopharyngeal carcinoma is an uncommon cancer but has a distinct racial and geographic distribution. Patient presents with constellation of signs and symptoms due to its vicinity to critical structures and are best treated by conformal concurrent chemo-radiotherapy. We present a case of 45-year-old male diagnosed with carcinoma nasopharynx, referred to us for radiotherapy after three cycles of neoadjuvant chemotherapy. As per the prevailing standard of care, patient was planned for radiotherapy by volumetric arc technique with concurrent cisplatin. Initial days of treatment were uneventful. After fourth week of treatment, patient developed persistent hiccup which was not relieved on conservative medications. Plan was re-evaluated and it revealed maximum dose of 54.6 Gy to the brainstem. Radiotherapy induced edema that could have stimulated vagus nerve leading to hiccups was suspected. Patient was started on injectable steroid and chlorpromazine. There was prompt recovery from the symptom within five days of conservative treatment.

A randomized, double-blinded feasibility trial of educational materials for hiccups in chemotherapy-treated patients with cancer.

PURPOSE: Chemotherapy can cause hiccups but few randomized controlled trials have focused on hiccups. This trial examined the feasibility of such research. METHODS: This single-institution, multi-site trial used phone recruitment for patients: (1) 18 years or older, (2) able to speak/read English, (3) with a working e-mail address, (4) with hiccups 4 weeks prior to contact, and (5) with ongoing oxaliplatin or cisplatin chemotherapy. The primary outcome was feasibility. Patients were randomly assigned to one of two sets of educational materials, each of which discussed hiccups and palliative options. The experimental materials were almost identical to the standard materials but provided updated content based on the published medical literature. At 2 weeks, patients responded by phone to a 5-item verbally administered questionnaire. RESULTS: This trial achieved its primary endpoint of recruiting 20 eligible patients within 5 months; 50 patients were recruited in 3 months. Among the 40 patients who completed the follow-up questionnaire, no statistically significant differences between arms were observed in hiccup incidence since initial contact, time spent reviewing the educational materials, and the troubling nature of hiccups. Twenty-five patients tried palliative interventions (13 in the experimental arm and 12 in the standard arm), most commonly drinking water or holding one's breath. Eleven and 10 patients, respectively, described hiccup relief after such an intervention. CONCLUSIONS: Clinical trials for chemotherapy-induced hiccups are feasible and could address an unmet need.

Effectiveness and safety of metoclopramide in treatment of intractable hiccup: a protocol of systematic review and meta-analysis.

INTRODUCTION: Hiccup is a common disease that not only occurred on adults but also on infants, which can severely do harm to patients' physical and psychological health. Metoclopramide has been reported to have effects on intractable hiccup. However, there is a limited evidence that describes the efficacy and safety of metoclopramide in the treatment of intractable hiccup. The aim of this article is to obtain evidence on the effectiveness and safety of metoclopramide in treating patients with intractable hiccup. METHODS AND ANALYSIS: We will search the following databases, including PubMed, Cochrane Library, Embase, Web of Science, CBM, Wan-fang, VIP database, CNKI and MEDLINE from their inception to 11 November 2021. All the randomised controlled trials associated with metoclopramide in treating intractable hiccup will be included. Articles screened, selected and extracted will be performed by two researchers independently. The risk of bias will be assessed by using the Cochrane Collaboration. We will carry out the meta-analysis by using RevMan V.5.4 software. PROSPERO REGISTRATION NUMBER: CRD42021293000.

A Medication Hiccup: Chlorpromazine-Induced Agranulocytosis in a 72-Year-Old Male.

INTRODUCTION: Agranulocytosis, a severe decrease or absence of neutrophils, is a side effect of several medications, including chlorpromazine. If not promptly recognized, it can lead to overwhelming infection, sepsis, and death. CASE PRESENTATION: A 72-year-old man with adenocarcinoma of the lung status-post recent lobectomy was admitted for postsurgical pain and electrolyte derangement. During his admission, he had intractable hiccups and was started on chlorpromazine 25 mg by mouth 3 times a day. Within a week, he developed pneumonia, type 1 respiratory failure, and a progressive neutropenia. Chlorpromazine-induced agranulocytosis was suspected and chlorpromazine was discontinued; however, the patient expired, with postmortem findings of aspergillus bronchopneumonia as cause of death. DISCUSSION: Chlorpromazine is a well-studied cause of agranulocytosis. This case is novel in its rapid time course of less than 1 week; most cases report the resultant agranulocytosis on the order of weeks rather than days. CONCLUSION: This case highlights an important need to recognize this medication side effect early so the offending agent may be stopped and the patient properly supported, so as to avoid the severe risk of neutropenic infection, sepsis, and death.

Persistent Hiccups Induced by Supratentorial Infarcts and Successful Treatment With a Combination of Perampanel and Baclofen: A Case Report.

CASE: A 52-year-old man developed a cerebral infarction from the right middle cerebral artery occlusion, and the infarction extensively damaged the right insula. Three months after the onset of the cerebral infarction, persistent hiccups appeared, occurring during sleep. The thoracic and abdominal cavities showed no lesions; hence, the hiccups were considered to be caused by central nervous system dysfunction. Administration of metoclopramide, chlorpromazine, and diazepam were ineffective, while levetiracetam had a partial effect. Combining perampanel with baclofen finally suppressed the symptoms. DISCUSSION: Lesions at the right insula impair respiratory reflex and may present with hiccups as a symptom of respiratory reflex disinhibition. Here, we review similar cases of treatment-resistant hiccups, as well as perampanel and baclofen efficacy in myoclonus cases. CONCLUSIONS: Our patient's case suggested that perampanel with baclofen may be effective for myoclonus due to respiratory reflex disinhibition and can be used to treat hiccups derived from cerebral infarctions.

Observation of Clinical Efficacy of Anisodamine and Chlorpromazine in the Treatment of Intractable Hiccup after Stroke.

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.

Effective Treatment of Intraoperative Hiccups With Chlorpromazine Under General Anesthesia Without Muscle Relaxants: A Case Report.

Hiccups are common reflexes and many treatment methods have been reported. Chlorpromazine is a known treatment option for hiccups, but its efficacy under general anesthesia remains unclear. We report the case of a patient with vagal schwannoma who developed hiccups while under general anesthesia. Muscle relaxants were not used because the patient was under neuromonitoring. The depth of anesthesia was deepened; however, the hiccups did not disappear. The hiccups were relieved by intravenous chlorpromazine administration (total; 5 mg), which allowed for surgery under neuromonitoring. This case indicates that chlorpromazine may be effective to treat hiccups under general anesthesia.

Olanzapine for cisplatin-induced hiccups: observations from a 338-patient study.

BACKGROUND: Several case reports suggest that olanzapine palliates hiccups. To our knowledge, however, no larger scale studies have confirmed that olanzapine prevents or palliatives hiccups. Hence, the current study sought to substantiate the conclusions from these earlier case reports. METHODS: This multi-site single institution study focused on cisplatin-treated cancer patients because this chemotherapy agent is associated with hiccups and because olanzapine is often used as an antiemetic with this agent. Relevant data were extracted from medical records. Hiccup incidence shortly after chemotherapy was compared between olanzapine exposed and non-exposed patients. Other relevant variables were also assessed descriptively in an exploratory manner. RESULTS: A total of 338 patients were studied. One hundred forty-one had received olanzapine and 197 had not. Twenty-one (6%) developed hiccups. Eleven (8%) of these patients with hiccups had received olanzapine, and 10 (5%) had not [odds ratio (OR): 1.58; 95% confidence interval (CI): 0.65-3.83; P=0.31]. Of note, hiccups were more often observed in men 17 of 188 (9%) than in women 4 of 150 (3%) (OR: 3.64; 95% CI: 1.20-11.02; P=0.01). CONCLUSIONS: Despite previous case reports and despite the relatively low incidence of hiccups in this study, it does not appear olanzapine prevents or palliates hiccups. The study of other promising agents is warranted. Furthermore, this study invites caution in relying on single case reports in making clinical decisions.
