Altitude sickness is a clinical syndrome that occurs with abrupt ascents to altitudes of 3000 metres and above. Symptoms include headache, malaise, fatigue, dizziness, anorexia, nausea and vomiting, and oliguria. At higher altitudes more severe illness resulting from pulmonary oedema or cerebral oedema can occur.

A simultaneous approach to revascularization for combined coronary and carotid disease today is well accepted. The discussion about combined procedures of carotid and aortoiliac occlusive disease is still going on. We operated upon 3 patients, aged 63,56 and 65 years, who suffered from carotid, aortoiliac and renal artery disease. Main symptoms were hypertensive crisis with pulmonary edema and intermittent claudication. Dizziness, transient ischemic attacks and slight renal insufficiency were present in two, one and two patients respectively. After recompensation a simultaneous operation was performed: carotid endarterectomy with inlying shunt, reconstruction and patch-plasty of the renal arteries and implantation of a aortofemoral artery bypass graft. Postoperative complications: hypertensive crisis, low output syndrome and oliguria (1 pt.) and deep vein thrombosis (1 pt.) could be treated conservatively. 10 and 12 months later the patients are symptom-free except one, who suffers from angina NYHA II. In conclusion we recommend carotid endarterectomy simultaneously with any major vascular procedure, if a critical stenosis is visualized to improve long-term survival in addition to reducing operative mortality.

Acute mountain sickness (AMS) affects, to varying degrees, all travelers to high altitudes (elevations greater than 5280 feet). In a small percentage of patients, AMS can lead to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE). Symptoms of AMS range from a combination of headache, insomnia, anorexia, nausea, and dizziness, to more serious manifestations, such as vomiting, dyspnea, muscle weakness, oliguria, peripheral edema, and retinal hemorrhage. Although the primary cause of these symptoms is related to the reduced oxygen content and humidity of the ambient air at high altitudes, the physiologic pathway relating hypoxemia to AMS and its sequelae remains unclear. Tips on self-diagnosis and symptom recognition are critical elements to be included in educating patients who are contemplating a trip to high altitudes. Preventive strategies include allowing 2 days of acclimatization before engaging in strenuous exercise at high altitudes, avoiding alcohol, and increasing fluid intake. Conditioning exercise for patients older than 35 years is also recommended before departure. A high-carbohydrate, low-fat, low-salt diet can also aid in preventing the onset of AMS. Acetazolamide (125 mg two or three times daily, or once at bedtime) has also been shown to reduce susceptibility to AMS and the incidence of HAPE and HACE. Although effective in treating cerebral symptoms of AMS, dexamethasone is not routinely recommended as a prophylactic agent for AMS.

A 57-year-old woman was scheduled to receive recombinant interferon-alpha retreatment for chronic active hepatitis C. During the course of therapy, the patient showed rapid onset of oliguria, dizziness, edema, and a pre-shock state. She was subsequently admitted to hospital and was diagnosed as having nephrotic syndrome. After admission, albumin-dominant proteinuria persisted despite the discontinuation of interferon therapy. Light microscopy of a renal needle biopsy specimen showed interstitial lymphoid cell infiltration, but no marked changes of the glomeruli and no staining for immunoglobulin or complement. Electron microscopy showed diffuse effacement of the glomerular epithelial foot processes, leading to a diagnosis of minimal change nephrotic syndrome with interstitial nephritis. Proteinuria resolved after the initiation of oral prednisolone therapy (1 mg/kg per day). The number of patients with chronic hepatitis C requiring interferon retreatment is increasing rapidly. We herein report this rare case of acute onset of nephrotic syndrome during interferon-alpha retreatment.

Alisma orientale (Sam.) Juzep. (Alismataceae) is a traditional and famous Chinese medicinal herb. Its rhizomes, which possess versatile bioactivities, are commonly used to treat oliguria, edema, gonorrhea with turbid urine, leukorrhea, diarrhea and dizziness. Approximately 120 compounds have been isolated from A. orientale. Terpenoids have been identified as A. orientale's characteristic constituents, which include protostane triterpenoids and guaiane sesquiterpenoids. The traditional medical uses of A. orientale in TCM have been evaluated in modern pharmacological studies, which have shown that A. orientale and its active constituents exhibit a wide range of bioactivities, such as diuretic, anti-urolithiatic, antinephritic, anti-atherosclerotic, immunomodulatory, and hepatoprotective activities. The medicinal potential of A. orientale makes it an ideal candidate for new drug development. Further studies are still required to identify its bioactive constituents, and elucidate the structure-activity relationship and detailed mechanisms of action. Additionally, the use of the other medicinal parts of A. orientale may reduce resource waste and afford novel secondary metabolites.
