We report here the case of a patient suffering from hemophagocytic syndrome (HPS) associated with toxic shock syndrome (TSS). A 50-year-old man was admitted because of fever, watery diarrhea and shortness of breath. Clinical analysis revealed systemic cyanosis, sunburn-like erythema and septic shock. Staphylococcus aureus was identified from both blood and(More)
POEMS syndrome is a rare plasma cell disorder, characterized by polyneuropathy, organomegaly, endocrinopathy, serum monoclonal protein, and skin lesions. Although not included in the acronym, renal lesions also are characteristic of this disease and sometimes require dialysis therapy. We treated a 61-year-old woman with POEMS syndrome with high-dose(More)
In healthy subjects, the blood volume (BV) increases rapidly after postural change from standing to the supine position. However, little is known about the effect of postural change on BV in long-term hemodialysis (HD) patients. Therefore, we have examined the BV change caused by adopting the supine position from standing by continuous hematocrit(More)
Epidermal growth factor (EGF) inhibits amiloride-sensitive Na(+) conductance in the apical membrane of the isolated rabbit cortical collecting duct. However, there is no information on the relationship between electrolyte transport and tyrosine kinase. We examined the effect of EGF on transport of potassium and chloride as well as sodium and the roles of(More)
We developed a new optical device (Nikkiso) to assess changes through blood volume monitoring (BVM) during hemodialysis and were able to determine the ideal levels in which changes in blood volume percentage (BV%) occur among hemodialysis patients in one hemodialysis center. We evaluated both the reliability of BVM and these ideal levels in a multicenter(More)
The following conventional calcium correction formula (Payne) is broadly applied for serum calcium estimation: corrected total calcium (TCa) (mg/dL) = TCa (mg/dL) + (4 - albumin (g/dL)); however, it is inapplicable to chronic kidney disease (CKD) patients. A total of 2503 venous samples were collected from 942 all-stage CKD patients, and levels of TCa(More)
The incidence of cholesterol crystal embolism (CCE) has increased along with increases in the prevalence of atheromatous diseases and intravascular procedures. CCE frequently results in the deterioration of renal function, which sometimes leads to end-stage renal failure. Although there has been no established therapy for CCE, the possibility that(More)
Hemodialysis(HD) patients are at risk for thiamine deficiency because of low intake and accelerated loss of thiamine during HD. We report here an HD patient, an 82-year-old woman, who developed acute encephalopathy due to thiamine deficiency with hyperammonemia. She was admitted to Nishikawa Town Hospital due to pneumonia and was treated with ABPC/SBT for(More)
Type 2 diabetic kidney disease (DKD) is frequently accompanied by uncontrollable hypertension due to the sodium sensitivity inherent in DKD and to diuretic-resistant edema. In general, diuretics are effective in treating this condition, but thiazide diuretics are thought to be innocuous in advanced chronic kidney disease (CKD). We examined the(More)
BACKGROUND/AIMS Patients undergoing hemodialysis (HD) have higher occurrence rates of cerebral diseases, including uremic encephalopathy, cognitive impairment, dementia, and cerebrovascular disease, than the general population. During HD, ultrafiltration is performed to maintain an adequate fluid condition and is associated with subsequent blood volume (BV)(More)
