BACKGROUND: In Asian countries, glycerol solution that contains fructose (5%) is often used for management of brain edema. However, glycerol and fructose may cause severe hypoglycemia and metabolic acidosis in patients with fructose-1,6-bisphosphatase (FBPase) deficiency, even under stable conditions. The aim of the present study was to determine whether glycerol solution was used for brain edema during acute metabolic decompensation of hypoglycemia and metabolic acidosis in patients with unrecognized FBPase deficiency in Japan and to examine a long-term prognosis of the patients who had this kind of severe metabolic decompensation with or without glycerol therapy. METHODS: A retrospective study of 20 children with FBPase deficiency was conducted, based on their medical records. RESULTS: Six of the 20 children were given glycerol solution for the presence or possibility of brain edema during acute metabolic decompensation of hypoglycemia and metabolic acidosis; two of the six patients administered with glycerol were given dialysis. In four patients treated with glycerol alone without dialysis, two had no brain edema before glycerol administration but it developed later after the administration. These four patients treated with glycerol alone died or developed severe neurological complications. Fourteen patients who were not treated with glycerol solution had no brain edema and showed good prognosis. CONCLUSIONS: Glycerol solution, which contains fructose in Asian countries including Japan, should not be used as an osmotic agent for treatment of brain edema in patients who have hypoglycemia and retention-type metabolic acidosis, until FBPase deficiency is ruled out by measuring blood concentration of lactate. 相似文献

1. The plasma level of Z-300 reached a maximum (Cmax) at 30?min after the oral administration of Z-300 to dog, and disappeared from the systemic circulation with a halflife of 8-9 h. The bioavailability of Z-300 was 52% after the oral administration of Z-300, 3?mg/kg. At doses ranging from 3 to 30?mg/kg, Cmax and AUC (area under the plasma concentration-time curve) were proportional to the dose. 2. The plasma level of Z-300 reached Cmax at 10?min after the oral administration of Z-300 to rat, and disappeared from the systemic circulation with a half-life of 0.8-1.6 h. The bioavailability of Z-300 was 39% after the oral administration of Z-300, 10?mg/kg, and there was a non-linear relationship between the plasma level-time profile of Z-300 and the administered dose (3-50?mg/kg). 3. The binding of Z-300 to plasma protein was 92% in man, 65% in dog and 25% in rat. It is suggested that these species differences were due to the content of α1-acid glycoprotein (α1-AG), because Z-300 bound more strongly to α1-AG than to albumin. 相似文献

Cholestatic hepatocellular carcinoma, which grows into the bile duct and causes obstructive jaundice, is rare and difficult to diagnose. A case is presented in which cholestatic hepatocellular carcinoma was detected by deposit of Lipiodol. This is also the first case that was successfully treated by endoscopic retrograde biliary drainage and transcatheter arterial embolization. 相似文献

Intracranial pressure (ICP) measurements are fundamental in the present protocols for intensive care of patients during the acute stage of severe traumatic brain injury. However, the latest report of a large scale randomized clinical trial indicated no association of ICP monitoring with any significant improvement in neurological outcome in severely head injured patients. Aggressive treatment of patients with therapeutic hypothermia during the acute stage of traumatic brain injury also failed to show any significant beneficial effects on clinical outcome. This lack of significant results in clinical trials has limited the therapeutic strategies available for treatment of severe traumatic brain injury. However, combined application of different types of neuromonitoring, including ICP measurement, may have potential benefits for understanding the pathophysiology of damaged brains. The combination of monitoring techniques is expected to increase the precision of the data and aid in prevention of secondary brain damage, as well as assist in determining appropriate time periods for therapeutic interventions. In this study, we have characterized the techniques used to monitor patients during the acute severe traumatic brain injury stage, in order to establish the beneficial effects on outcome observed in clinical studies conducted in the past and to follow up any valuable clues that point to additional strategies for aggressive management of these patients. 相似文献

Plasma macrophage colony‐stimulating factor (M‐CSF) levels were measured in 13 haematologic patients treated with autologous peripheral blood stem cell transplantation (PBSCT). Six of the patients showed an increase in M‐CSF peak levels (> 3000 pg/ml) during the conditioning and stem cell infusion period. The peak levels of M‐CSF in this phase correlated with thrombomodulin levels, indicating the endothelial origin of plasma M‐CSF. However, the M‐CSF levels were not influenced by TNFα. More patients with high M‐CSF levels (> 5000 pg/ml) suffered from organ failure than those with lower M‐CSF levels. These results suggest that high M‐CSF levels may correlate with cellular or organ damage in patients treated with PBSCT. 相似文献

Background and objective: Cytomegalovirus (CMV) infection is a life‐threatening condition in patients with diffuse parenchymal lung diseases (DPLDs), who are receiving immunosuppressive therapy. The aim of this study was to describe the clinical features of CMV infection and to propose a strategy for managing CMV infection in patients with DPLD who are receiving immunosuppressive therapy. Methods: A retrospective longitudinal observational study was performed on 69 patients with DPLDs (39 with acute/subacute onset, 30 with chronic onset) who were receiving immunosuppressive therapy and were positive for CMV pp65 antigen (CMV‐pp65Ag) in peripheral blood leukocytes (PBLs). Results: Clinical CMV disease and subclinical CMV antigenaemia developed in 23 and 46 patients, respectively. The cut‐off level of CMV‐pp65Ag indicating clinical CMV disease, as determined by receiver operator characteristic curve analysis, was 7.5 cells per 5 × 104 PBLs. Multivariate analysis revealed that early CMV infection was associated with acute/subacute onset of underlying DPLD and with respiratory dysfunction at the commencement of immunosuppressive therapy. Multivariate analysis also suggested that the acute/subacute onset of underlying DPLD, a CMV‐pp65Ag titre of >7.5 cells per 5 × 104 PBLs, and C‐reactive protein levels ≥10 mg/L indicated a poor prognosis. Conclusions: We recommend that CMV‐pp65Ag antigenaemia of >7.5 cells per 5 × 104 PBLs in patients with DPLD should be treated with ganciclovir. Patients with lower levels of CMV‐pp65Ag antigenaemia should be closely monitored or treated with ganciclovir if the clinical findings suggest a poor prognosis. 相似文献

BACKGROUND: The kidney eliminates the major fraction of plasma oxalate. It is well known that oxalate is freely filtered by glomeruli and secreted by the proximal tubules. However, the renal handling of oxalate in distal nephrons, which is considered as playing an important role in stone formation, remains obscure. METHODS: At 15-180 min after intravenous injection of 14C-oxalate to rats, the intrarenal localization of radioactivity was quantitatively measured by the radioluminographic method using a bioimaging analyzer. Tissue radioactivity was compared with plasma, and urinary radioactivities were measured by a liquid scintillation counter. The control study was conducted with 14C-inulin. RESULTS: The radioactivity of 14C-oxalate in the papilla was 10 times greater than in the cortex and eight times greater than in the medulla 180 min after injection when almost no radioactivity was present in the urine. In contrast, the radioactivity of 14C-inulin was nine times less in the papilla than in the cortex at the same time. CONCLUSION: Oxalate remains in the renal papilla for an extended period. This accumulation of oxalate may be attributed to calcium oxalate crystal fixation along the deep nephron which is considered to be the first step of stone formation. 相似文献

Abstract: We studied 25 cases of minute (less than 5 mm in a diameter) superficial depressed neoplastic lesions during the period of March 1990 to September 1991. These depressed neoplastic lesions were recognized by colonoscopy as asteroid redness with surrounding elevation. The thickness and height of the surrounding elevations were modified by air volume. Occasionally, they seemed according to the air volume to be elevated lesions, though their fundamental form was confirmed as being superficial depressed lesions from observations of histopathological sections and using a dissecting microscope. The endoscopic figures were emphasized by sprinkling them with Methylene Blue. All of the minute depressed neoplastic lesions were histopathologically diagnosed as being tubular adenoma. For the purpose of confirming the histopathological character of the depressed neoplastic lesions (n = 25) and distinguishing them from conventional elevated adenomas (n = 71) of the same diameter, we compared the incidences of glandular crowding, nuclear stratification, nuclear pleomorphism and loss of nuclear polarity in two groups. Glandular crowding and nuclear pleomorphism were recognized significantly more often in the depressed neoplastic lesions than in the elevated adenomas. Although most of the minute depressed neoplastic lesions were fundamentally adenomas, because of their unique histopathologic character, they could give new insight into the development of colon cancer. 相似文献

Postventricular Pacing Preexcitation. Antegrade conduction over a Kent bundle was transiently manifested after the cessation of ventricular overdrive pacing in two patients; otherwise, the heart behaved as if it had a concealed accessory pathway. Conventional electrophysiologic study suggested either a longitudinal dissociation of an accessory pathway or closely located double accessory pathways. The mechanism of the transient manifestation of ventricular preexcitation was discussed. (J Cardiovasc Electrophysiol, Vol. 3, pp. 423–430, October 1992) 相似文献
