Theophylline is commonly believed to stimulate central respiratory centers. We studied the effect of oral theophylline therapy on ventilatory responses to hypercapnia and hypoxia during a double-blind placebo-controlled trial with a slow release oral theophylline preparation. We measured hypercapnic
The diagnosis and quantification of severity of acute mountain sickness (AMS) continue to be problematic. What symptoms should be included in a score and how to weigh any given symptom in the total score remain matter of debate. Seventy seven healthy male (n=43) and female (n=34) volunteers, aged
Nausea and vomiting during the infusion of cryopreserved peripheral blood stem cells (PBSC) are common. The aim of this study was to explore the effect of lollipop with strawberry aroma on the infusion-related nausea and vomiting of cryopreserved autologous PBSCs. We compared 2 groups of adult
Acute mountain sickness (AMS) develops within a few hours after arrival at high altitude and includes headache, anorexia, nausea, vomiting, and malaise. This afflicts 15-25% of the general tourist population at moderate altitudes. High-altitude cerebral edema (HACE) is considered to be the end stage
A 58 year old male with a history of cirrhosis (hepatitis B and C), a long smoking history, and a recently diagnosed high-grade transitional cell carcinoma of the bladder wall presented three days after a biopsy procedure with abdominal pain, nausea, and new hypoxemia on room air. The chest
BACKGROUND
SR4554 is a fluorine-containing 2-nitroimidazole, designed as a hypoxia marker detectable with 19F magnetic resonance spectroscopy (MRS). In an initial phase I study of SR4554, nausea/vomiting was found to be dose-limiting, and 1400 mg m(-2) was established as MTD. Preliminary MRS studies
BW12C (5-[2-formyl-3-hydroxypenoxyl] pentanoic acid) stabilizes oxyhaemoglobin, causing a reversible left-shift of the oxygen saturation curve (OSC) and tissue hypoxia. The activity of mitomycin C (MMC) is enhanced by hypoxia. In this phase II study, 17 patients with metastatic colorectal cancer
Hyponatraemia is the most common electrolyte disorder encountered in clinical practice. Symptomatic hyponatraemia reflects brain damage because of cerebral swelling. Some coexisting factors such as extreme ages, hypoxia and female sex are associated with poor prognosis. In this report, we describe
Indigo carmine (also known as 5,5'-indigodisulfonic acid sodium salt or indigotine) is a blue dye that is administered intravenously to examine the urinary tract and usually is biologically safe and inert. Indigo carmine rarely may cause adverse reactions. We treated a 66-year-old man who had
Respiratory insufficiency is a major cause of death in Duchenne muscular dystrophy (DMD). The earliest sign is a hypoventilation which appears in REM sleep. We administered 20 mg of clomipramine hydrochloride before sleep to two DMD patients with periodic nocturnal hypoxemia. The complaints such as
Hypobaric hypoxia can produce neuropsychological disorders such as insomnia, dizziness, memory deficiencies, headache and nausea. Here we report the changes in adrenomedullin (AM) expression observed in rats exposed to hypobaric hypoxia and different times of reoxygenation. AM immunoreactivity was
OBJECTIVE
Postoperative nausea and vomiting (PONV) is one of most frequently encountered problems after dental treatment of mentally and/or motor disabled patients under sedation or general anesthesia. In this study, we aimed to investigate whether PONV incidence in disabled patients differs between
OBJECTIVE
To perform a Phase I study of SR-4554, a fluorinated 2-nitroimidazole noninvasive probe of tumor hypoxia detected by (19)F magnetic resonance spectroscopy (MRS).
METHODS
SR-4554 administration, on days 1 and 8, was followed by plasma sampling for pharmacokinetic studies and by three MRS
Importance: Opioid-induced ventilatory depression and hypoxemia is common, severe, and often unrecognized in postoperative patients. To the extent that nonopioid analgesics reduce opioid consumption, they may decrease postoperative
For people unaccustomed to high altitude, exposure to height often leads to Acute Mountain Sickness, with headaches, difficulty breathing and gastrointestinal symptoms. Nausea and loss of appetite may result in less calorie intake and weight loss. At altitudes greater than 4000 m about 50-80% of
