ABSTRACT
Neuromyelitis optica spectrum disorder (NMOSD) may present with area postrema syndrome, which is characterized by intractable vomiting and hiccups. Hyponatremia is common in NMOSD and is mostly associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In contrast to SIADH, cerebral salt wasting syndrome (CSWS) causes hyponatremia, which is associated with severe natriuresis and extracellular volume depletion in patients with cerebral disease. To our knowledge, hyponatremia associated with CSWS has not been reported in a patient with NMOSD. Here, we describe a NMOSD presenting with hyponatremia, which may be caused by CSWS following area postrema syndrome.

There have been few reports on an antiemetic effect of bakumondoto. An 84 year old man was referred to the department of internal medicine for Kampo treatment of intractable vomiting since having a gastrectomy 6 years previously. He had experienced persistent regurgitation of gastric fluids at dawn and antiemetic and antiacid drugs were of little help. He had had a gastrojejunostomy 4 years previously for an intestinal obstruction. After the gastrojejunostomy, vomiting persisted despite of the administration of antiacids, rikkunshito or daikenchuto. Physical examination revealed only slight edema of the legs. An upper gastrointestinal series, blood tests and head CT scan revealed no specific vomiting cause. After referral to our department, we tried hangeshashinto, and shinbuto in vain. Then we prescribed bakumondoto. He reported that the frequency of his vomiting reduced in 3 weeks, and that the vomiting disappeared in 2 more weeks. Thus we consider that not only cough but also vomiting can be treated with bakumondoto.
