Hemolytic uremic syndrome (HUS) can be clinically classified into two types: typical cases with a diarrheal prodrome of association with E. coli O157, and atypical cases without antecedent diarrhea. However, HUS is not common in Taiwan. To evaluate the clinical course, complications and outcome of HUS in children, and to identify the risk factors for mortality, retrospectively, seven cases of HUS in our hospital in the past 6 years were studied. Six of them were boys, and one was a girl. Their ages ranged from 0.67 to 3 years. None of them were preceded by diarrheal prodrome. Acute renal failure, hypertension and liver involvement were noted in all cases. Stroke and seizure developed in three of the cases with sequelae. Two cases progressed into end-stage renal disease (ESRD). One case developed acute respiratory distress syndrome (ARDS). Two cases (28.5%) expired. ESRD especially associated with ARDS was highly related to mortality.

Acute renal failure in Burkitt lymphoma is commonly the result of tumor lysis syndrome. We present a 15-year-old boy who developed hypertension, seizures, and acute renal failure due to extrinsic compression of the bladder and ureters by a large retrovesical Burkitt lymphoma. The causes of acute renal failure in Burkitt lymphoma and the incidence of acute urinary obstruction in this disease are reviewed.

A 14-year-old girl had an acute episode of rhabdomyolysis after vigorous exercise and seizures. Laboratory studies revealed elevated creatine phosphokinase (CPK) activity and myoglobinuria without acute renal failure, as well as mild indirect hyperbilirubinemia, and hyperuricemia. The elevated CPK activity, mild indirect hyperbilirubinemia, and hyperuricemia persisted during a 10-month follow-up period, during which chronic hemolysis without overt anemia was also noted. A muscle biopsy specimen from the left biceps muscle revealed occasional muscle fiber necrosis and mild excess of glycogen accumulation on periodic acid-Schiff staining. Histochemical reactions were negative with phosphofructokinase (PFK) stain when fructose-6-phosphate was used as the substrate, but positive when fructose 1,6-bisphosphate was used as the substrate. These findings confirmed the diagnosis of muscle PFK deficiency (Tarui's disease), which is a defect of glycolysis in muscles and erythrocytes. Less than 40 such patients have been reported to date. When a specific metabolic myopathy is suspected in children with rhabdomyolysis, symptoms of hemolysis should also be sought to identify Tarui's disease. To the best of our knowledge, this is the first case of Tarui's disease identified in Taiwan.

Nontraumatic rhabdomyolysis is an important but under-recognized cause of acute renal failure. In alcoholics, rhabdomyolysis most frequently develop following muscle necrosis during alcohol-induced coma, but has also been described rarely in those without prolonged coma or seizures. We describe a patient who developed myoglobinuric acute renal failure requiring dialysis following binge drinking in the absence of convulsions or coma. The renal biopsy showed acute tubular necrosis with pigment casts.

A 9-year-old boy with nephrotic syndrome was transferred to our hospital because of acute renal failure and disturbance of consciousness after high-dose methylprednisolone therapy. He developed severe headache, visual disturbance, and generalized seizures. Brain computed tomography (CT) scan revealed multiple, bilateral, low-density areas in the parieto-occipital lobes. Magnetic resonance imaging (MRI) disclosed a high signal intensity area on T2-weighted images and a low signal intensity area on T1-weighted images in the same lesion. Follow-up brain CT scan and MRI, 2 weeks after the first studies, showed complete resolution of the abnormal lesions, which suggested the diagnosis of reversible posterior leukoencephalopathy syndrome (RPLS). Hypertension and high-dose methylprednisolone administration to the patient in the nephrotic state may be causes of this uncommon syndrome in this case. This is the first report of RPLS in nephrotic syndrome with hypertension not associated with cyclosporine administration.

Acute tumor lysis syndrome (TLS) occurs frequently in hematologic malignancies such as high-grade lymphomas and acute leukemia, which are rapidly proliferating and chemosensitive tumors. It occurs rarely in solid tumors and has never been reported in gastric adenocarcinoma. Typical biochemical findings of acute tumor lysis syndrome are hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia in patients with a malignancy. Rapid changes of these electrolytes may cause cardiac arrhythmia, seizure, acute renal failure and sudden death. Therefore, as soon as it is detected, it should be taken care of immediately. Until now almost all cases of TLS associated with solid tumor have developed after cytoreductive therapy in chemosensitive tumors. We report here a case of spontaneous acute tumor lysis in a patient of advanced gastric cancer with hepatic metastases and multiple lymphadenopathy. The biochemical finding of TLS improved with the management and tumor burden also showed slight response to the one cycled combination chemotherapy but the patient died of progressive pneumonia.

Acute renal failure is the most common complication of rhabdomyolysis, with an 8-20% reported incidence. In particular, rhabdomyolysis associated with acute renal failure is frequently observed in critically ill patients, with a 6-16% reported incidence in Intensive Care Units. Dialytic treatment is necessary to correct hydroelectrolytic imbalance and renal function alterations and it may be a pathogenetic therapy by myoglobin removal. In the present study we evaluated our experience on patients suffering from rhabdomyolysis and acute renal failure subjected to dialytic treatment. We retrospectively studied 28 patients, 17 admitted in our Intensive Care Unit (ICU-patients) and treated by continuous renal replacement therapy (particularly by continuous venovenous hemofiltration, continuous venovenous hemodialysis and continuous venovenous hemodiafiltration) and 11 admitted in our Nephrology Department (NICU-patients) and treated by high-efficiency daily hemodialysis. We excluded one ICU-patient from the study because she was affected with lung end-stage neoplasia and it would have been difficult to evaluate the effects of the dialytic treatment on RML biochemical index and on her final outcome. ICU-patients were older, with a mean age of 64 +/- 10 yrs, and were suffering from MODS and typical elderly diseases, such as cardiac and respiratory chronic failure, except from 3 patients with acute liver failure resulting from poisoning, who were relatively younger. In NICU-patients, instead, the mean age was 36 +/- 16 yrs and the causes of RML were narcotic drugs abuse, repetitive seizures and vigorous exercise, more frequently observed in young people. In three relatively older NICU-patients RML was due to lipid lowering drugs assumption. Before starting the dialytic treatment, in ICU-patients CPK plasma level was 2615 +/- 3586, while K+ was 5.10 +/- 1.08 and sCr was 5.69 +/- 4.06 In NICU-patients, on the other hand, CPK was 14273 +/- 9266, while K+ was 5.75 +/- 0.92 and sCr was 5.9 +/- 0.4. ICU-patients mortality rate was 50% (8/16 patients) in spite of the good recovery of renal function and the biochemical RML indexes improvement. In NICU-patients, instead, only one patient died for septic complications (he was a heroin-addict and suffered from overdose syndrome). Early dialytic treatment of RML allows not only to avoid life-threatening complications (first of all the acute renal failure) but moreover it's a pathogenetic treatment because it removes great amount of myoglobin from the plasma. Beside this, continuous renal replacement therapy allows a successful management of critically ill patients with severe hemodynamic conditions. Nevertheless, the final outcome may be very different between ICU- and NICU-patients, with a higher mortality rate in ICU-patients, suffering from MODS.

The importance of an acute encephalopathy associated with nontyphoidal salmonellosis has recently been recognized, but the disease entity has been poorly established. In this study, we describe two encephalopathic patients associated with nontyphoidal salmonellosis. The patients exhibited a rapid evolution of coma after the onset of lethargy or seizure. Fever and diarrhea due to salmonellosis preceded these events. Secondary factors inducing encephalopathies, such as severe dehydration, sepsis, meningitis, electrolyte or metabolic disturbances, acute renal failure, and multiple organ failure, were excluded in the differential diagnosis at the onset of encephalopathic features. These clinical findings and rapid development of encephalopathic features from localized intestinal infection without any significant abnormalities in a variety of blood tests may suggest a toxic etiology. However, endotoxin was not found in serum from both patients. From these results, we conclude that nontyphoidal salmonellosis can cause a toxic encephalopathy syndrome, like shigellosis or verocytotoxin-producing Escherichia coli infection.

Reversible posterior leucoencephalopathy syndrome (RPLS) has previously been described in patients who have renal insufficiency, eclampsia, hypertensive encephalopathy and patients receiving immunosuppressive therapy. The mechanism by which immunosuppressive agents can cause this syndrome is not clear, but it is probably related with cytotoxic effects of these agents on the vascular endothelium. We report eight patients who received cyclosporine A (CSA) after allogeneic bone marrow transplantation or as treatment for severe aplastic anemia (SSA) who developed posterior leucoencephalopathy. The most common signs and symptoms were seizures and headache. Neurological dysfunction occurred preceded by or concomitant with high blood pressure and some degree of acute renal failure in six patients. Computerized tomography studies showed low-density white matter lesions involving the posterior areas of cerebral hemispheres. Symptoms and neuroimaging abnormalities were reversible and improvement occurred in all patients when given lower doses of CSA or when the drug was withdrawn. RPLS may be considered an expression of CSA neurotoxicity.

Doxylamine succinate is an antihistaminic drugwith additional hypnotic, anticholinergic and local anesthetic effects first described in 1948. In Korea and many other countries, it is a common-over-the counter medication frequently involved in overdoses. Clinical symtomatology of doxylamine succinate overdose includes somnolence, coma, seizures, mydriasis, tachycardia, psychosis, and rhabdomyolysis. A serious complication may be rhabdomyolysis with subsequent impairment of renal function and acute renal failure. We report a case of acute renal failure and acute pancreatitis complicating a doxylamine succinate intoxication.
