hiccup/nausea

The area postrema (AP) is a small, circumventricular organ located in the dorsal medulla and is characterized by an anastomosed capillary network with no blood-brain barrier. It contains the chemoreceptor trigger zone for vomiting, which is activated by noxious stimuli in the blood. Lesions to the

Neuromyelitis optica (Devic's disease) is a chronic autoimmune disease associated with the production of anti-bodies to aquaporin-4 (AQP4). Area postrema lesions is the third, after optic neuritis and myelitis, syndrome of opticomyelitis-related disorders. Clinical symptoms of this disorder include

Vomiting and hiccups can be the manifestations of numerous systemic and neurological illnesses. Intractable nausea, vomiting and hiccups (INH) are reported as possible initial manifestations of neuromyelitis optica (NMO), but not correctly identified. Awareness of these atypical presentations is

A 45-year-old female was positive for anti-aquaporin-4 antibody with disturbance of consciousness, respiratory failure, and ophthalmoplegia associated with extensive brain stem involvement with intractable hiccup and nausea as an initial manifestation. Her level of consciousness and state of

Nausea, vomiting, and hiccups are troubling complications associated with sedation and general anesthesia. This article will review the basic pathophysiology of these events and current recommendations for their prevention and management.

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

Dexamethasone is likely to play a role in the etiology of hiccups in patients receiving cisplatin-based regimens. Two hundred seventy-seven patients received three doses of ondansetron 8mg intravenously (IV) at 4hour intervals plus dexamethasone 20mg IV from the start of chemotherapy, followed by

A 61-year-old female, having intractable hiccups, nausea, and syncope. Her systolic blood presure decreased by 30 mmHg on sitting position from supine position. Sinus arrest lasting more than three seconds were detected 52 times per day by 24 hour Holter electrocardiography. Brain MRI disclosed a

BACKGROUND Intractable hiccup and nausea (IHN) are unique symptoms in neuromyelitis optica (NMO). Recent studies have strongly suggested that the pathogenesis of NMO is closely associated with anti-aquaporin-4 (AQP4) antibody. However, clinical implications of IHN and the relationship with anti-AQP4

A 48-year-old female with multiple sclerosis (MS) accompanied by intractable hiccups of over one month' duration and the sleep apnea syndrome was reported. This MS patient had been well controlled until September 16, 1991 when she experienced nausea, vomiting and hiccups. The patient was admitted to
