Intractable hiccups may develop with cyclophosphamide infusion

Hiccups in Cancer Patients Receiving Chemotherapy: A Cross-Sectional Study

CONTEXT

Hiccups are a symptom in cancer patients but it's less researched.

OBJECTIVES

The aimed to determine of prevalence of hiccups and treatment approach used in hiccup management in cancer patients receiving chemotherapy for nursing care.

METHODS

This study used a descriptive cross-sectional design with self-reported questionnaires and was conducted from November 2018-May 2019 in Turkey. For collection of the data, a Patient Information Form (sociodemographic and disease characteristics), and a Hiccups Evaluation Form were used for the patients.

RESULTS

Hiccups were observed in 37 (23%) of the 160 patients who met the criteria for inclusion in the study. The great majority of the patients suffering from hiccups were male (65.9%) and the type of cancer in the majority of these patients was gastrointestinal cancer (54.1%). It was determined that the duration of hiccups in 83.8% of patients observed with hiccups was between 0 and 48 hours, that the average severity of their hiccups was 3.81 ± 2.25 (0-10), and that hiccups in 59.5% of these patients was of low severity. It was found that only 10.8% of patients suffering from hiccups used pharmacological methods for relief and that 27% used nonpharmacological methods.

CONCLUSION

The results of the study showed that over one-fifth of cancer patients suffered from hiccups. This situation reveals that hiccups are an important symptom that needs to be carefully emphasised in oncology practice.

Hiccup: mystery, nature and treatment

Hiccup is the sudden onset of erratic diaphragmatic and intercostal muscle contraction and immediately followed by laryngeal closure. The abrupt air rush into lungs elicits a "hic" sound. Hiccup is usually a self-limited disorder; however, when it is prolonged beyond 48 hours, it is considered persistent whereas episodes longer than 2 months are called intractable. A reflex arc involving peripheral phrenic, vagal and sympathetic pathways and central midbrain modulation is likely responsible for hiccup. Accordingly, any irritant in terms of physical/chemical factors, inflammation, neoplasia invading the arc leads to hiccups. The central causes of hiccup include stroke, space occupying lesions and injury etc, whereas peripheral causes include lesions along the arc such as tumors, myocardial ischemia, herpes infection, gastroesophageal reflux disease and applied instrumentations on human body etc. Besides, various drugs (eg, anti-parkinsonism drugs, anesthetic agents, steroids and chemotherapies etc) are the possible etiology. An effective treatment of persistent hiccup may be established upon the correct diagnosis of lesion responsible for the serious event. The pharmacotherapy of hiccup includes chlorpromazine, gabapentin, baclofen, serotonergic agonists, prokinetics and lidocaine. Non-pharmacological approaches such as nerve blockade, pacing, acupuncture and measures to hold breathing are also successful. Finally, alternative medicines and remedies are convenient to treat hiccups with uncertain effect. In conclusions, hiccup is likely to result from lesions involving the hiccup reflex arc. The lesion may need to be localized correctly for ablative treatment in patients with intractable hiccup. Apart from lesion ablation, drugs acting on reflex arc may be effective, while some other conventional measures may also be tried.

Persistent hiccups associated with epidural ropivacaine in a newborn

OBJECTIVE

To report a case of persistent hiccups associated with epidural ropivacaine in a newborn infant.

CASE SUMMARY

A term female infant (3.05 kg) received epidural ropivacaine for pain control during and after an operative procedure to correct a tracheoesophageal fistula. Three intermittent doses of ropivacaine were administered during the operative period (total dose 2.29 mg/kg) followed by a continuous epidural (caudal) infusion (0.1% ropivacaine; initial dose 0.23 mg/kg/h plus fentanyl 0.46 μg/kg/h). The infant was extubated in the recovery area and transferred to the intensive care unit. Within hours of transfer, she developed persistent hiccups. The epidural infusion was titrated for pain control, up to 0.32 mg/kg/h (ropivacaine). The hiccup frequency increased to every 10-30 seconds, with the patient appearing hypotonic with lip trembling and intermittent tongue fasciculation. An electroencephalogram did not show any epileptiform activity or focal features consistent with seizure activity. The epidural infusion was reduced to 0.26 mg/kg/h (ropivacaine), with dramatic improvement in hiccups and tone. The infusion was discontinued and complete resolution of hiccups was observed.

DISCUSSION

Ropivacaine is commonly used for infiltration anesthesia and peripheral and epidural block anesthesia. Use of the Naranjo probability scale determined that our patient's hiccups were probably caused by ropivacaine. To our knowledge, this is the first report of persistent hiccups associated with epidural ropivacaine.

CONCLUSIONS

Clinicians should consider the potential of neurotoxicity, manifested as persistent hiccups, when epidural ropivacaine is administered to young infants.

Severe hiccups during chemotherapy: corticosteroids the likely culprit

Hiccups generally are self-limiting and of short duration. Those lasting more than 48 h or recurring at frequent intervals are termed persistent. There are numerous causes of hiccups, with medications implicated only rarely. While hiccups are usually benign, severe attacks may lead to exhaustion, eating difficulties, and affect quality of life. We report a case of severe hiccups in a patient receiving chemotherapy (oxaliplatin, 5-fluorouracil, leucovorin) for metastatic colorectal cancer. Hiccups began on the day following chemotherapy and continued constantly for over 30 h until relief was obtained by sucking the juice of a fresh lemonade. A similar pattern occurred in the next two chemotherapy cycles. Dexamethasone had been prescribed as prophylaxis against emesis and this was considered a possible cause. Withholding dexamethasone in the next cycle led to elimination of hiccups without having an impact on control of nausea and vomiting. A number of case reports have linked corticosteroids, particularly dexamethasone, to the occurrence of hiccups. Antineoplastic agents have occasionally been reported as causing hiccups; however, in most of these cases, corticosteroids, as part of the treatment protocol or as antiemetics, may have been a more likely cause. This case serves an as important reminder that adverse effects appearing during chemotherapy may not necessarily be due to antineoplastic agents. In the case of hiccups, oncology health professionals should review all medications and non drug-related factors before assigning causality. J Oncol Pharm Practice (2009) 15: 233—236.

Microvascular decompression for intractable singultus: technical case report

OBJECTIVE

Intractable singultus is a rare but significantly disruptive clinical phenomenon that often accompanies other diseases but can present in isolation due entirely to intracranial pathology. We report a case of intractable singultus that improved after microvascular decompression and present a comprehensive review of singultus by discussing its similarity to other cases of microvascular decompression, its history and etiology, and its evolutionary basis.

CLINICAL PRESENTATION

The patient exhibited intractable singultus for 15 years, resistant to multiple medical regimens.

INTERVENTION

Microvascular decompression to relieve pressure on the tenth cranial nerve and medulla oblongata resulted in near total resolution of the singultus.

CONCLUSION

Neurovascular compression should be considered a potentially reversible cause of intractable singultus, a significantly disabling clinical phenomenon.

Hiccup and neurosurgeons: a report of 4 rare dorsal medullary compressive pathologies and review of the literature

OBJECTIVE

The aim of this study was to present 4 rare cases of medullary compressive lesions presenting with IH, to discuss the indications for neurosurgical decompression in such cases, and to review the possible etiologies of IH briefly.

METHODS

The reported cases include (1) a 19-year-old adolescent boy and a 21-year-old man with Chiari I malformation and cervical syrinx compressing or tightening the cervico-medullary junction; (2) a 35-year-old man with ependymoma extending from the lower half of the fourth ventricle to C1/C2 junction and compressing this part of the medulla; and (3) a 16-year-old adolescent boy who was referred to the emergency department in severe distress because of IH, occurring as a result of a distal PICA aneurysm located on the floor of the lower triangle of the fourth ventricle.

RESULTS

Surgical decompression in all the cases was successful in withholding the hiccups.

CONCLUSION

The dorsal medullary area is not an unusual location for genesis of hiccup. When encountering a case of IH, appropriate CNS imaging studies should be included in the evaluation protocol.
