Motion sickness provides a unique setting for the study of nausea. Studies of illusory self-motion have linked nausea and objective measures of gastric dysrhythmias and the stress hormones vasopressin and epinephrine. Electrogastrographic methods utilize Ag-AgCl electrodes placed on the abdominal surface in the epigastric region to record electrogastrograms (EGGs), a noninvasive measure of gastric myoelectrical activity. The EGG frequencies of interest are the normal range (2.4-3.6 cpm), tachygastrias (3.6-9.9 cpm), and bradygastrias (1.0-2.4 cpm), and duodenal respiratory frequencies (10.0-15.0 cpm). Illusory self-motion or vection is produced with a rotating drum. Minutes before vection-induced nausea is reported, the baseline EGG signal shifts into tachygastrias or mixed tachygastrias and bradygastrias. Quantitative analyses show that the percentage of power in the tachygastria range correlates with the intensity of nausea. Plasma vasopressin levels correlate positively with intensity of nausea. Asian subjects have higher intensity nausea and higher vasopressin levels compared with Caucasian subjects, indicating a potential genetic susceptibility to vection-induced motion sickness and nausea. Vection-induced motion sickness represents an experimental model of acute-onset nausea with accompanying symptoms such as headache, drowsiness, cold sweating, and fatigue. Illusory self-motion is a purely central nervous system (visual-vestibular) stimulation that evokes dramatic shifts in gastric electrical activity and significant release of the posterior pituitary hormone vasopressin. Central nervous systems pathways that evoke gastric dysrhythmias and release vasopressin may also have a pathophysiologic role in the cyclic vomiting syndrome.

A 73-year-old man with general malaise and nausea following a common cold diagnosed by a local physician was found to have multiple hepatocellular carcinomas with enlarged bilateral adrenal glands, combined with adrenal insufficiency. Hydrocortisone replacement improved the symptoms and laboratory findings. Autopsy findings revealed that each adrenal gland was completely replaced by the tumor measuring 11 cm in diameter, and no adrenal tissue was recognized. Histologically, the adrenal tumors, as well as the liver tumors, were moderately differentiated Edmondson type II hepatocellular carcinomas. This is a second report of adrenal insufficiency due to hepatocellular carcinoma as a primary site of metastatic adrenal tumor.

The causes of pituitary apoplexy are unclear. We report a case of pituitary apoplexy presenting with headache and nausea. On June 17th, 1997 a 74-year-old woman had complained of retro-orbital headache, fever and vomiting. A cold was diagnosed for which she recurred medication. In addition to the previous symptoms she was getting to lose appetite. She was admitted to our hospital for further examination and treatment on June 21. On admission neurological examination showed left pupil mydriasis, the left eye had no light reflex and the right eye had only a slight response to the light. She could hardly move both eyeballs up. Laboratory data showed a normal white blood cell count and the CRP was 16.2 mg/dl. Lumbar puncture showed 97 mg/dl total protein and 82 cells per microliter, most of which were lymphocytes. We diagnosed viral infection based on the evidence of clinical symptoms and lumbar puncture data. The patient was treated with gamma-globulin and improved. From the 16th day of sickness we recognized symptoms of oculomotor paralysis and the syndrome of inappropriate antidiuretic hormone. On the 23rd day of sickness we strongly suspected pituitary apoplexy based on transaxial MR images. After absorption of intra-tumor hemorrhage, the oculomotor symptoms recurred. We finally reached a diagnosis of pituitary apoplexy based on pathological material, MR images, symptoms and laboratory data. We must think of pituitary apoplexy when we see an aged out-patient with severe headache, nausea, vomiting and oculomotor paralysis. It was difficult to diagnose this disease in the early time course of the disease.

The authors report a case of tianeptine abuse in a 30 year-old woman. After a medical prescription of the recommended dosage of 12.5 mg 3 times daily of oral tianeptine for a depressive illness, the patient spontaneously increased the dosage which after two months reached 150 tablets per day. No severe toxic effects were observed. As adverse effects, the patient, in the beginning of this high treatment period suffered from nausea, vomiting, abdominal pain, anorexia with weight loss, constipation. These side effects progressively disappeared. The biological tolerance was excellent, and hepatic parameters were not affected. The patient experienced and seek a psychostimulant effect. After seven months of such a therapy, she was hospitalized to undergo a withdrawal. The discontinuation of the tianeptine treatment occurs in four days. A withdrawal syndrome marked by myalgia, and cold feeling was transient, and alleviated by sedative phenothiazine (cyamemazine) and myorelaxant benzodiazepine (tetrazepam).

We encountered 4-year-old boy who developed paroxysmal cold hemoglobinuria (PCH) in the middle of August. He was admitted due to progressive jaundice and pallor following fever and nausea. Laboratory data revealed severe anemia, increased serum indirect bilirubin and LDH, and decreased serum haptoglobin. Direct/indirect Coombs tests were positive. These findings yielded a diagnosis of autoimmune hemolytic anemia. Serological test for syphilis was negative. The patient's symptoms and signs promptly subsided after treatment with prednisolone, which was started on the 2nd hospital day. The patient has been in a disease-free state for 16 months without any medication. After discharge, he was finally given a diagnosis of PCH because a Donath-Landsteiner test was positive. The antibody belonged to an IgM subclass and showed anti-I specificity. Considering that development of PCH is common in winter, this case was unique because it developed in August. We speculated that exposure to a cool air-conditioned atmosphere prior to hospitalization and the cooling mechanism of the body after admission were involved in the summer onset of PCH and its prolonged clinical course.

The patients was a 43-year-old woman whose chief complaints were nausea and heaviness of the heads. There was a history of toxemia of pregnancy. The patient had previously taken Tenshin Tokishigyaku-ka-goshuyu-shokyo-to for two years because of cold sensitivity. Fever, thirst, and loss of appetite developed from approximately 18 months after she started treatment with the Chinese herbal preparation, and she presented at our outpatient clinic 2.5 years later. On initial examination, deterioration of renal function was evident and the serum creatinine level was 3.4 mg/dl. A renal biopsy specimen showed marked interstitial fibrosis without inflammatory cell infiltration, leading to the diagnosis of Chinese herbs nephropathy (CHN). Steroid therapy was started on the 36th hospital day after a sharp rise in the serum creatinine level to 5.1 mg/dl. This resulted in the rapid improvement of renal function and reduction of the serum creatinine to 2.6 mg/dl by 8 weeks after the initiation of treatment. In a study on the use of steroids for patients with progressive moderate renal dysfunction caused by Chinese herbs, Vanherweghem et al. reported that the progression of renal failure was appreciably slowed in patients given steroids when compared with the control group. We were also able to slow the progression of renal dysfunction in our patient by steroid therapy, although the prognosis of CHN is generally considered to be very poor.

Although migraine is the main chronic headache in childhood and adolescence, it remains extensively misdiagnosed. Schematically, migraine is a severe headache evolving by stereotyped attacks frequently associated with marked digestive symptoms (nausea, vomiting, abdominal pain). Throbbing pain, sensitivity to sound, and light (and sometimes odors) are frequent additional symptoms. The attack is sometimes preceded by a visual or sensory aura. Rest brings relief, and sleep often ends the attack. Childhood migraine prevalence varies between 5 and 10%. Migraine episodes are frequently triggered by several factors: emotional stress (school pressure, vexation, excitement, upset), hypoglycemia, lack or excess of sleep (weekend migraine), sensory stimulation (loud noise, bright light, strong odor, heat or cold, etc.), sympathetic stimulation (sport, physical exercise). Attack treatments must be given at an early stage, oral ibuprofen (10 mg/kg) being particularly recommended. If the oral route is not available because of nausea or vomiting, rectal or nasal routes have then to be used. Non-pharmacological treatments (biofeedback and interventions combining progressive muscle relaxation) have demonstrated good efficacy as prophylactic measures. Daily prophylactic pharmacological treatments are prescribed as the second line after failure of non-pharmacological treatments.

In childhood and adolescence, migraine is the main essential chronic headache. This diagnosis is extensively underestimated and misdiagnosed in pediatric population. Lacks of specific biologic marker, specific investigation or brain imaging reduce these clinical entities too often to a psychological illness. Migraine is a severe headache evolving by stereotyped crises associated with marked digestive symptoms (nausea and vomiting); throbbing pain, sensitivity to sound, light are usual symptoms; the attack is sometimes preceded by a visual or sensory aura. During attacks, pain intensity is severe, most of children must lie down. Abdominal pain is frequently associated, rest brings relief and sleep ends often the attack. The prevalence of the migraine varies between 5p.100 and 10p.100 in childhood. At childhood, headache duration is quite often shorter than in adult population, it is more often frontal, bilateral (2/3 of cases) that one-sided. Migraine is a disabling illness: children with migraine lost more school days in a school year, than a matched control group. Migraine episodes are frequently triggered by several factors: emotional stress (school pressure, vexation, excitement: upset), hypoglycemia, lack of sleep or excess (week end migraine), sensorial stimulation (loud noise, bright light, strong odor, heat or cold.), sympathetic stimulation (sport, physical exercise). Attack treatments must be given at the early beginning of the crisis; oral dose of ibuprofen (10mg/kg) is recommended. If the oral route in not available when nausea or vomiting occurs, the rectal or nasal routes have then to be used. Non pharmacological treatments (biofeedback and interventions combining progressive muscle relaxation) have shown to have good efficacy as prophylactic measure. Daily prophylactic pharmacological treatments are prescribed in second line after failure of non-pharmacological treatment.

1.4 G, 1.7 G, and 2.0 G of +Gz and 60 minutes centrifugation was adopted to 20 healthy male subjects using 1.8 m radius centrifuge equipped to Nihon University School of Medicine. G was applied from lower G, considering G training effect for the subjects. Effects on performance decline and side effects of such a short-arm centrifugation were especially observed in the experiments, because this size of centrifuge could be used in space station in future for a strong countermeasure of cardiovascular deconditioning, demineralization from bone, etc. G training effect was observed same as higher and rapid G acceleration in fighter pilot. Subjects suffered from many types of discomfort; such as sensation of heaviness of diaphragm, cold sweat, nausea, irritable feeling, arrhythmia, tachycardia, rapid decrease of blood pressure, which sometimes caused interruption of G load. As 2.0 G and 60 minutes centrifugation seemed very tough load to the subjects, there should be necessary some G suit or other countermeasure, if we apply a higher G and/or longer G duration. Performance decline due to the load commonly continued for 1 hour or so. Side effects were observed in relation to neuro-vestibular, cardio-vascular, and autonomic nervous system.

A 21-year-old woman experienced severe headache and nausea one hour after taking pills containing 160 mg of phenylpropanolamine for common cold. She had no previous history of drug abuse or hypertension. Physical examination revealed slight left-sided hemiparesis. Her blood pressure was 100/52 mmHg. Subcortical hemorrhage was noted in the right frontal lobe with a cranial computed tomography. On the seventh hospital day, cerebral angiography demonstrated with segmental narrowing of a branch of the right anterior cerebral artery, indicating the presence of focal angitis. This finding disappeared on the 35th hospital day. In the majority of the reported cases of the intracerebal hemorrhage associated with the ingestion of phenylpropanolamine, focal angitis rather than induced hypertension is considered to be a causative factor for hemorrhage. Thus, we would like to emphasize that the administration of phenylpropanolamine should be avoided, even to the patients without hypertention or past history of intracerebral hemorrhage.
