Intractable hiccup and nausea with periaqueductal lesions in neuromyelitis optica

Intractable hiccup and nausea (IHN) was found in eight of 47 cases of relapsing neuromyelitis optica (NMO) (17%) but in none of 130 cases of multiple sclerosis (MS). IHN resolved with methylprednisolone. In six cases, MRI detected linear medullary lesions involving the pericanal region, the area postrema, and the nucleus tractus solitarius. Like long and centrally located myelitis, a linear medullary lesion causing IHN may distinguish NMO from MS.

Hiccups: causes and cures

Hiccups result from a wide variety of conditions that act on the supraspinal hiccup center or that stimulate or disinhibit the limbs of its reflex arc. While scores of hiccup remedies have been reported over the centuries, no single "cure" stands out as being the most effective. Measures that stimulate the uvula or pharynx or disrupt diaphragmatic (respiratory) rhythm are simple to use and often help to speed the end of a bout of otherwise benign, self-limited hiccups. Such manueuvers may also terminate persistent hiccups. Drug therapy usually becomes necessary for more intractable hiccups; chlorpromazine and metoclopramide being two of the most widely employed agents for this purpose. Physical disruption of the phrenic nerve, hypnosis, and acupuncture are other modes of therapy that have been used in severe cases. Because so many reports of hiccup "cures" are based on anecdotal experience rather than controlled clinical studies, I review the available treatments to provide a rational approach for the management of hiccups.

Effectiveness of acupuncture and related therapies for palliative care of cancer: overview of systematic reviews

Acupuncture and related therapies such as moxibustion and transcutaneous electrical nerve stimulation are often used to manage cancer-related symptoms, but their effectiveness and safety are controversial. We conducted this overview to summarise the evidence on acupuncture for palliative care of cancer. Our systematic review synthesised the results from clinical trials of patients with any type of cancer. The methodological quality of the 23 systematic reviews in this overview, assessed using the Methodological Quality of Systematic Reviews Instrument, was found to be satisfactory. There is evidence for the therapeutic effects of acupuncture for the management of cancer-related fatigue, chemotherapy-induced nausea and vomiting and leucopenia in patients with cancer. There is conflicting evidence regarding the treatment of cancer-related pain, hot flashes and hiccups, and improving patients' quality of life. The available evidence is currently insufficient to support or refute the potential of acupuncture and related therapies in the management of xerostomia, dyspnea and lymphedema and in the improvement of psychological well-being. No serious adverse effects were reported in any study. Because acupuncture appears to be relatively safe, it could be considered as a complementary form of palliative care for cancer, especially for clinical problems for which conventional care options are limited.

Effect of antisecretory therapy on atypical symptoms in gastroesophageal reflux disease

The effect of proton pump inhibitor (PPI) therapy on extraesophageal or atypical manifestations of gastroesophageal reflux disease (GERD) remains unclear. This study aimed to evaluate the prevalence of atypical manifestations in patients with acid reflux disease and the effect of PPI treatment. Patients with symptoms and signs suggestive of reflux were enrolled. Erosive esophagitis was stratified using the Los Angeles classification. Demographic data and symptoms were assessed using a questionnaire and included typical symptoms (heartburn, regurgitation, dysphagia, odynophagia), and atypical symptoms (e.g., chest pain, sialorrhea, hoarseness, globus sensation, chronic coughing, episodic bronchospasm, hiccup, eructations, laryngitis, and pharyngitis). Symptoms were reassessed after a 3-month course of b.i.d. PPI therapy. A total of 266 patients with a first diagnosis of GERD (erosive, 166; non-erosive, 100) were entered in the study. Presentation with atypical symptoms was approximately equal in those with erosive GERD and with non-erosive GERD, 72% vs 79% (P = 0.18). None of the study variables showed a significant association with the body mass index. PPI therapy resulted in complete symptom resolution in 69% (162/237) of the participants, 12% (28) had improved symptoms, and 20% (47) had minimal or no improvement. We conclude that atypical symptoms are frequent in patients with GERD. A trial of PPI therapy should be considered prior to referring these patients to specialists.

Gabapentin as a drug therapy of intractable hiccup because of vascular lesion: a three-year follow up

BACKGROUND

Persistent and intractable hiccups indicate multiple neurologic and extraneurologic disorders. Chronic hiccup is not so rare in patients suffering from stroke: its impact on quality of life and on rehabilitation management is substantial, and it may be closely related to aspiration pneumonia, respiratory arrest and nutritional depletion.

REVIEW SUMMARY

Intractable hiccups can be associated with potentially fatal consequences and safe management may require inpatient rehabilitation. It has been suggested that hiccups could be a form of myoclonus, caused by repeated and abnormal activity of the solitary inspiratory nucleus. Because of this cause we decided to treat intractable hiccups in patients with ischemic lesions of the medulla with a short course of gabapentin.

CONCLUSIONS

The results were promising, with the immediate disappearance of the hiccups, and the complete absence of side effects. The 36-months follow up was favorable to all the patients, who, after 6 days of treatment remain asymptomatic.

Hoquet diabolique: intractable hiccups as a manifestation of multiple sclerosis

In three patients, intractable hiccups occurred as part of the symptomatology of multiple sclerosis. In one patient intractable hiccups were the presenting complaint, and in another patient exacerbations of symptoms were almost always heralded by intractable hiccups. Intractable hiccups occur in a variety of diseases, including many that affect the brainstem and cervical cord, but have not been reported in multiple sclerosis. The hiccup may be a "primitive" gastrointestinal reflex that is disinhibited by lesions such as multiple sclerosis plaques. Carbamazepine was successful in arresting the hiccups in one of the cases presented.

Hiccups

Hiccups result from a variety of causes and serve no known physiologic function. Although most episodes are time-limited, hiccups may become protracted, with serious consequences. Assessment of hiccups entails a focused history and physical examination coupled with selected laboratory tests. If a correctable malady is discovered, treatment should address the underlying disorder. However, if the cause remains unknown, therapeutic options include nonpharmacologic and pharmacologic measures. Since hiccups are common, this review provides a practical approach to the management of this bothersome symptom.

Psychogenic polydipsia with hyponatremia: report of eleven cases

Psychogenic polydipsia is an uncommon clinical disorder characterized by excessive water-drinking in the absence of a physiologic stimulus to drink. The excessive water-drinking is well tolerated unless hyponatremia supervenes. This report describes 11 patients with psychogenic polydipsia and hyponatremia (ten men and one woman) who were collectively hospitalized a total of 70 times for treatment of complications of this disorder. This group differs from the classical patient with psychogenic polydipsia, ie, a hospitalized schizophrenic, in that none was institutionalized and there was a high incidence of chronic alcoholism (10), intractable hiccups (7), self-induced vomiting (6), and laboratory evidence for rhabdomyolysis (5).

Lesional location of lateral medullary infarction presenting hiccups (singultus)

BACKGROUND

Hiccups are an infrequent result of lateral medullary infarction. Their importance may be underestimated and they can cause distress, exhaustion, and aspiration. Hiccups in lateral medullary infarction remain poorly understood

OBJECTIVE

To evaluate the relation between the lesional loci of lateral medullary infarction and hiccups.

METHODS

51 patients with lateral medullary infarction were investigated by magnetic resonance imaging within three days of the onset of infarction. Seven of the 51 patients developed hiccup.

RESULTS

All patients with hiccups had middle level lateral medullary lesions, including two with lower level lesions and four with upper level lesions. In the middle level lateral medullary lesions, dorsolateral lesions were most often involved. All patients with lateral medullary infarction presenting with hiccups also had vertigo, dizziness, nausea, vomiting, and dysphagia.

CONCLUSIONS

The observations suggest that middle level and dorsolateral lesion locations in lateral medullary infarction frequently induce hiccups.

Termination of intractable hiccups with digital rectal massage

A 60-year-old man with acute pancreatitis developed persistent hiccups after insertion of a nasogastric tube. Removal of the latter did not terminate the hiccups which had also been treated with different drugs, and several manoeuvres were attempted, but with no success. Digital rectal massage was then performed resulting in abrupt cessation of the hiccups. Recurrence of the hiccups occurred several hours later, and again, they were terminated immediately with digital rectal massage. No other recurrences were observed. This is the second reported case associating cessation of intractable hiccups with digital rectal massage. We suggest that this manoeuvre should be considered in cases of intractable hiccups before proceeding with pharmacological agents.

Intractable hiccup induced by brainstem lesion

Four patients with brainstem lesions presented with intractable hiccup and mild to moderate neurological signs. Two of the patients had been initially diagnosed as having a psychogenic cause for their hiccup. Magnetic resonance imaging (MRI) demonstrated brainstem infarction in one case, tuberculoma at the junction of the medulla oblongata and the cervical spinal cord in two, and a vermian tuberculoma compressing the brainstem in one. The brainstem infarct and one of the medullary tuberculoma were not detected on high resolution enhanced computed tomography. The 3 patients with CNS tuberculoma were free of hiccup 1-5 months after antituberculous chemotherapy. It is proposed that hiccup is not an abnormal reflex, but a myoclonus generated by repetitive activity of the "inspiratory solitary nucleus" due to release of higher nervous system inhibitory/-regulatory control. The neuroanatomical network and the mechanisms underlying the formation of intractable hiccup are outlined. The value of MRI in the initial diagnosis and follow-up of patients with intractable hiccup due to brainstem lesions is emphasised.

Persistent hiccup as presenting symptom in medulla oblongata cavernoma: a case report and review of the literature

A rare case of persistent intractable hiccup as presenting symptom of cavernous angioma in the medulla oblongata is reported. Pathophysiologic hypotheses about the triggering mechanism of hiccup are discussed, with special reference to the causes affecting the central nervous system. A review of the literature concerning medullary lesions presenting with persistent hiccup is also reported. Finally we have included some brief considerations about cavernous angiomas and the patterns of their clinical presentation, focusing on those located in the medulla oblongata.

Management of hiccups in the palliative care population

There are close to a hundred causes for hiccups, or singultus, the most common of which are gastrointestinal. Causes may be natural or drug induced, and the same agents that are used to treat hiccups may also induce them. Hiccups can be classified by their duration, as follows: up to 48 hours, acute; longer than 48 hours, persistent; and more than two months, intractable. Treatment options for hiccups can include both pharmacologic and nonpharmacologic agents. If the cause of hiccups can be identified, it is, of course, preferable to direct the treatment at that cause. However many times a cause cannot be identified; in this case, general measures or treatments should be instituted. Intractable hiccups can occur in the palliative care population. When they do, it can be extremely distressing and have a significant impact on quality of life. Pharmacologic approaches are often the most rational therapies for these patients. Baclofen seems to be a promising drug for use with both palliative care and perioperative patients, and using garabentin as an add-on to baclofen may also be a reasonable option to consider

Vagus nerve stimulation for chronic intractable hiccups

✓ Intractable hiccups are debilitating and usually a result of some underlying disease. Initial management includes vagal maneuvers and pharmacotherapy. When hiccups persist despite medical therapy, surgical intervention rarely is pursued. Cases described in the literature cite successful phrenic nerve blockade, crush injury, or percutaneous phrenic nerve pacing. The authors report on a case of intractable hiccups occurring after a posterior fossa stroke. Complete resolution of the spasms has been achieved to date following the placement of a vagus nerve stimulator.

Development of behaviors in preterm infants: relation to sleeping and waking

BACKGROUND

Although nurse clinicians and researchers use infant behaviors to indicate the responses of preterm infant to stimulation, little is known about how the biological factors of development, sleeping and waking states, infant characteristics, and infant illness severity affect preterm infant behaviors.

OBJECTIVE

This study examined the development of eight infant behaviors over the preterm period and determined the relation of these behaviors to sleeping and waking and to infant characteristics and illness severity.

METHODS

Seventy-one preterm infants were observed once per week from 7:00 p.m. to 11:00 p.m. from the time they were no longer critical until term or discharge. The occurrence of four sleep-wake states and eight behaviors were recorded every 10 seconds during the observations.

RESULTS

Negative facial expressions increased over the preterm period; sighs, startle/jerks, jitters, and the likelihood of having hiccups decreased. Infant characteristics had only minor effects: boys had more negative facial expressions, and longer mechanical ventilation was associated with more sighs and jitters. All behaviors showed state-related differences in frequency. In addition, only startle/jerks and jitters showed the same developmental patterns within each state.

CONCLUSIONS

Significant development of infant behaviors occurs over the preterm period but involves changes not only in the absolute percentage of each behavior but also in the percentages within each sleeping and waking state. Thus, preterm infant behaviors cannot be used clinically for assessment without consideration of the state in which they occur.

Respiratory problems in advanced cancer

Respiratory problems are an important issue in the palliative care setting, not only from a diagnostic and therapeutic point of view but also from emotion-related aspects involving both the patients and their families and also caregivers. In this paper we consider some of the most common respiratory problems, such as dyspnea, infections, hemoptysis, hiccup. A review of the literature was performed with reference to the frequency, diagnosis and management of the above respiratory problems in patients in advanced and terminal stages of the disease. Particular emphasis was given to the importance of communication with the patients and their families, which is considered a crucial point in the care and the cure of such patients.

Intractable hiccups during stroke rehabilitation

OBJECTIVE

To study the frequency of intractable hiccups during stroke rehabilitation and the impact on rehabilitation management.

DESIGN

Case series, retrospective chart review.

SETTING

Inpatient stroke rehabilitation floor within a tertiary care teaching hospital.

PATIENTS

Three patients admitted for stroke rehabilitation with hiccups of at least 48 hours out of 270 consecutive cases.

INTERVENTIONS

None.

MAIN OUTCOME MEASURE

Response to pharmacologic treatment.

RESULTS

All three subjects had pontine infarcts and required gastrostomy tube feedings and lengthy rehabilitation stays. Subjects suffered from significant complications including aspiration pneumonia, respiratory arrest, and nutritional depletion. Chlorpromazine treatment was terminated in all three subjects because of sedation that interfered with therapies. Treatment with carbamazepine was successful in only one patient; in the other two subjects, their hiccups were controlled with haloperidol or baclofen. All subjects were ultimately managed with a single agent.

CONCLUSIONS

Pharmacologic interventions for intractable hiccups must be tailored to the unique circumstances of the stroke rehabilitation patient. Intractable hiccups can be associated with potentially fatal consequences, and safe management may require an inpatient rehabilitation setting and multidisciplinary team approach to optimize the feeding management of this challenging population.

Hiccups. A case presentation and etiologic review

Hiccups (singultus) usually present as a common annoyance lasting for short periods. Rarely, they may be the harbinger of a serious disease. We present the case of a 19-year-old man in which intractable hiccups was the first and most prominent symptom of a serious underlying neurologic disorder. The patient had been examined by his pediatrician, and despite multiple medical regiments and physical maneuvers, his symptoms persisted. A thorough head and neck examination revealed a right-sided vocal cord paralysis. This finding prompted obtaining a magnetic resonance imaging scan, which demonstrated a type I Arnold-Chiari malformation associated with a large cervicothoracic syringomyelia. The patient was referred to the neurosurgical service and subsequently underwent a ventriculoperitoneal shunt placement. There was considerable initial improvement in his neurologic status and cessation of the hiccups. However, the symptoms recurred within 1 month. The case report as well as a brief review of the relevant pathophysiologic and etiologic considerations and several treatment modalities for hiccups is presented.

Persistent hiccup associated with thoracic epidural injection

Epidural steroid injections are commonly used to treat lumbosacral radicular and discogenic pain. When used in this manner, these agents can cause minor, transient systemic side effects and rarely result in any serious complications. Because adverse reactions are uncommon and transient, epidural injections are considered a safe therapeutic intervention. We describe the first case of persistent hiccups as a consequence of a thoracic epidural steroid injection in a patient with thoracic discogenic pain.

Intractable singultus: a diagnostic and therapeutic challenge

Hiccup or singultus is a repeated involuntary, spasmodic contraction of the diaphragm accompanied by a sudden closure of the glottis mediated by sensory branches of the phrenic and vagus nerves as well as dorsal sympathetic afferents. The principle efferent limb and diaphragmatic spasms are mediated by motor fibers of the phrenic nerve. Hiccup has been classified as a respiratory reflex and the central connection probably consists an interaction among the brainstem respiratory centers, phrenic nerve nuclei, medullary reticular formation and the hypothalamus. Chronic intractable hiccup may be due to brainstem seizures, and baclofen may be the long-awaited remedy for intractable hiccup as demonstrated in three illustrative cases.

A phylogenetic hypothesis for the origin of hiccough

The occurrence of hiccoughs (hiccups) is very widespread and yet their neuronal origin and physiological significance are still unresolved. Several hypotheses have been proposed. Here we consider a phylogenetic perspective, starting from the concept that the ventilatory central pattern generator of lower vertebrates provides the base upon which central pattern generators of higher vertebrates develop. Hiccoughs are characterized by glottal closure during inspiration and by early development in relation to lung ventilation. They are inhibited when the concentration of inhaled CO(2) is increased and they can be abolished by the drug baclofen (an agonist of the GABA(B) receptor). These properties are shared by ventilatory motor patterns of lower vertebrates, leading to the hypothesis that hiccough is the expression of archaic motor patterns and particularly the motor pattern of gill ventilation in bimodal breathers such as most frogs. A circuit that can generate hiccoughs may persist in mammals because it has permitted the development of pattern generators for other useful functions of the pharynx and chest wall muscles, such as suckling or eupneic breathing.

Comparison of propofol versus thiopentone with midazolam or lidocaine to facilitate laryngeal mask insertion

PURPOSE

To assess the ease of insertion of laryngeal mask airway (LMA) comparing propofol with lidocaine or midazolam followed by thiopentone and compare the costs with each technique.

METHODS

One hundred and fifty ASA 1 or 2 patients equally divided into three groups scheduled for elective surgery were recruited into this prospective, single blind, randomized, parallel groups study. Anaesthetic induction was achieved with 1 microgram.kg-1 fentanyl i.v. followed by either 2.5 mg.kg-1 propofol (group P), or a sequence of 1.5 mg.kg-1 lidocaine and 5 mg.kg-1 thiopentone (group LT), or midazolam 0.1 mg.kg-1 and, three minutes later, 5 mg.kg-1 thiopentone (group MT). The LMA was inserted by the blinded anaesthetist who assessed and graded the conditions for LMA insertion and noted any adverse responses (i.e., inadequate jaw relaxation, gagging, coughing, limb or head movement, hiccough and laryngospasm). Conditions were considered "excellent" if there were no adverse responses, and "satisfactory" if such a response was mild and transient.

RESULTS

Excellent or satisfactory conditions were observed in 48 (96%) patients in the midazolam-thiopentone group, 46 (92%) in the propofol group, and 34 (68%) in the lidocaine-thiopentone group (P = 0.0001). The incidence of gagging (P = 0.042), limb movement (P = 0.031), and laryngospasm (P = 0.0001) was higher in the lidocaine-thiopentone group.

CONCLUSIONS

With the above doses, a fentanyl-midazolam-thiopentone combination which is about 35% less expensive than fentanyl-propofol, provides equally good conditions for the insertion of LMA.
