Non-steroidal anti-inflammatory drugs (NSAID) are increasingly popular in hospital medicine and general practice and are readily available over the counter. The vast majority of healthy children who ingest therapeutic doses of NSAID for a limited duration tolerate them without any significant adverse effects. However, the risk of renal toxicity is potentially increased in situations where there is stimulation of the renin-angiotensin system such as with volume depletion or in pre-existing chronic renal disease. We describe four cases which illustrate this complication occurring in a children's hospital. We have not proven cause and effect, but further research is needed to define the true risk of the potential renal complications of NSAID in patients at risk of dehydration. 相似文献

We describe a 15 year old boy with renal hypouricemia who developed acute renal failure after a school athletics meeting, accompanied by appendicitis. During acute renal failure, the highest level of uric acid was 5.0 mg/dL, creatinine 7.9 mg/dL and urea nitrogen 58.6 mg/dL. After recovery, the serum uric acid fell to 0.9 mg/dL and the fractional excretion of uric acid (FEuA) exceeded the normal range. The probenecid and pyrazinamide tests showed that the patient had a total defect of uric acid reabsorption. This case suggested that strenuous exercise could be responsible for acute renal failure in patients with renal hypouricemia. 相似文献

PRF is encountered in 10-13% of adult heart transplants. Only one study of a single center's experience with PRF has been reported in pediatric patients. This study examines the effect of PRF on pediatric heart transplant outcome using the UNOS database. A total of 3598 patients met inclusion criteria, of whom 254 (7%) had PRF. The PRF group comprised 31 recipients requiring PRE and 223 recipients requiring POST. Compared with No-PRF patients, PRE patients had similar survival rate and POST patients had decreased survival rate at 30 days, one, five, and 10-yr post-transplant (p < 0.001). PRF patients also had significantly lower graft survival at one, five, and 10 yr (p < 0.001). Risk factors for developing PRF included ECMO, ventilator, and inotropic support at listing and CHD as the listing diagnosis. PRF increased the duration of hospital stay and the incidence of chronic severe renal dysfunction. PRF that requires POST (whether or not it began pretransplant) has a significant negative impact on pediatric heart transplant outcome. Specific characteristics identify patients at particular high risk of developing PRF. 相似文献

Acute scrotum is a rare complication of acute Kawasaki disease (KD), less well recognized than other disease manifestations. We describe the cases of two patients, aged 59 months and 19 months, with hydrocele testis in the acute phase of KD. Scrotal ultrasound and trans‐illumination were used in the diagnosis of hydrocele testis. One patient underwent eventual surgical intervention. We reviewed the literature for a better understanding of the pathogenesis of scrotal symptoms in acute KD and investigated the clinical importance of hydrocele testis. Careful further clinical observation may elucidate the true incidence of this extracardiac symptoms, thereby clarifying the diagnostic value of this possible complication in acute KD. 相似文献

A 10-year-old Japanese girl developed acute renal failure following a 100-meter dash during physical training at school. After the run, she experienced intense pain in the loins with nausea and vomiting lasting more than 12 h. On the following morning, she was found to have mild proteinuria and acute renal failure (ARF). Serum creatinine and blood urea nitrogen were elevated, but the serum uric acid level was normal (3.1 mg/dL). With recovery of renal function over the ensuing days, hypouricemia (0.6 mg/dL) became evident in the patient. Although the pathophysiological association between renal hypouricemia and ARF is not known, oxygen free radicals have been implicated in the pathogenesis for ischemic-reperfusion ARF. Superoxide production by neutrophils stimulated by N-formyl methionine leucyl-phenylalanine was normal in the patient both before and following exercise. Pyrazinamide and probenecid tests were undertaken on both the patient and her parents, who had borderline hypouricemia, to determine their renal tubular handling of uric acid. Results showed that the patient and her mother had a subtotal reabsorption defect, while the father had defective postsecretory uric acid reabsorption. 相似文献

A prospective study was performed to investigate the validity of renal failure index (RFI) or fractional excretion of sodium (FENa) in preterm infants. The subjects were 128 newborn infants, 72 with oliguria and 56 without renal dysfunction (control). Oliguric infants were divided into two categories: acute renal failure (ARF) and prerenal failure (PRF), according to creatinine clearance (Ccr). Furthermore, all subjects were divided into four groups according to gestation, that is, 38 infants with gestational age of 25–28 weeks (group 1), 28 with 29–30 weeks (group 2), 38 with 31–36 weeks (group 3) and 24 of > 37 weeks (group 4). As a result, differentiation between ARF and PRF was valid when the RFI or FENa was used in infants of > 29 weeks gestation (groups 2, 3 and 4). Although infants of > 31 weeks gestation (groups 3 and 4) who present with an RFI > 3 or an FENa > 3% may be diagnosed as having ARF, infants in group 2 with an RFI of > 8 or an FENa of > 6% may be diagnosed as having ARF. For the infants in group 1, the application of RFI or FENa for diagnosis of ARF may be limited because of some overlap among the groups. 相似文献

A case of P. falciparum malaria with acute renal failure is reported. The urinary sodium of 42 mEg/L pointed towards a tubular
pathology. There was no significant intravascular hemolysis as serum bilirubin was normal and plasma hemoglobin only mildly
elevated. The pathogenesis of acute tubular necrosis due to heavy parasitemia is discussed. The other interesting feature
which the patient exhibited was alternate day fever in the hospital and the peripheral smear showing only gametocytes repeatedly.
Gametocytes do not give rise to symptoms. The patient responded well to quinine hydrochloride and the gametocytes disappeared.
There is no satisfactory explanation for this phenomenon. 相似文献

Background: The aim of the present study was to determine, using the score for neonatal acute physiology and perinatal extension II (SNAPPE‐II), whether there is an association with acute renal failure (ARF) and whether it is possible to identify newborns at risk for ARF prior to a rise in creatinine in newborns. Methods: Information on postnatal risk factors and SNAPPE‐II on the first day of life (non‐ARF group, n= 475; ARF group, n= 78) were collected. Renal failure was defined as serum creatinine level >1 mg/dL and >1.3 mg/dL (for ≥33 weeks and <33 weeks, respectively) after 48 h of life. Results: In newborns with ARF (n= 78), the median (range) of SNAPPE‐II and mortality rate were significantly higher than those of the control group. Patent ductus arteriosus (PDA), disseminated intravascular coagulation (DIC), SNAPPE‐II, and resuscitation were identified as independent predictors of ARF in infants on forward stepwise logistic regression. Sepsis, respiratory distress syndrome, ARF, DIC, and SNAPPE‐II were identified as independent predictors of mortality in infants on the same analysis. Conclusions: SNAPPE‐II on the first day of life was significantly higher among babies with ARF, suggesting a positive association between higher scores and the development of ARF and mortality, but based on receiver operating characteristic curve results, SNAPPE‐II at admission did not enhance the assessment of risk for ARF prior to a rise in creatinine. 相似文献

Urinary tract infections, renal abscess formation and acute renal failure (ARF) after salmonella infection are rarely reported in children. We present a previously healthy teenager who developed ARF with renal abscess formation after salmonella infection, in whom we believe that acute salmonella pyelonephritis was the main causative factor for ARF and not dehydration, shock or rhabdomyolysis, which have already been described in the literature. With prolonged antibiotic treatment and adequate hydration, the boy’s condition improved, but chronic kidney disease was unfortunately inevitable. Conclusion: Salmonella pyelonephritis has, according to our knowledge, not yet been described to be the main causative factor of ARF in previously healthy children, as was the case in our patient. Long‐term antibiotic treatment of at least 6 weeks is probably a must in such patients, even though chronic kidney disease could not have been prevented. 相似文献

BACKGROUND: Despite anticoagulant therapy, many patients with Kawasaki disease and giant coronary artery aneurysm develop myocardial infarction. These patients have a high risk of sudden death, but the etiology is not clear. We studied autonomic function and the possibility of malignant ventricular arrhythmia through heart rate variability. METHODS: We studied six Kawasaki disease patients with myocardial infarction and 16 normal controls. Heart rate variability was investigated using a 24 h electrocardiogram. We assessed the standard deviation from the mean of the normal R-R intervals (SDNN), the proportion of adjacent R-R intervals with a difference greater than 50 msec (pNN50) and the root-mean square of successive R-R differences as time-domain analysis (rMSSD). We assessed very low-frequency power, low-frequency power (LF), high-frequency power (HF) and the LF/HF ratio in frequency-domain analysis. RESULTS: There was no significant difference in SDNN, but there was a significant difference in pNN50 and rMSSD. Patients with Kawasaki disease showed lower HF and higher LF/HF than normal controls. CONCLUSION: Our findings suggest that patients with Kawasaki disease and myocardial infarction show decreased vagal activity, which could cause malignant arrhythmia. 相似文献

BACKGROUND: Although seizures occur in association with meningitis or encephalitis in Kawasaki disease, febrile convulsions in Kawasaki disease are considered to be extremely rare. The aim of the present study is to elucidate the incidence of febrile convulsion in the acute phase of Kawasaki disease, in Niigata City General Hospital, Niigata, Japan. METHODS: The study included 177 patients with Kawasaki disease. Patients ranged in age from 2 months to 10 years (mean age 26.89 +/- 22.44 months). The study included 105 males and 72 females. The clinical records of Kawasaki disease patients were examined retrospectively. RESULTS: Febrile convulsions were not recognized in these 177 patients throughout the course of the disease, despite the presence of a high grade fever and their young age. However, eight of the 177 patients had experienced simple febrile convulsions during other febrile illness except for those with Kawasaki disease. In the acute phase of Kawasaki disease, only two patients showed generalized convulsion associated with prolonged consciousness disturbance and pleocytosis in the cerebrospinal fluid. CONCLUSION: The incidence of febrile convulsions in the acute phase of Kawasaki disease might be extremely low, confirming the results of previous reports. Kawasaki disease is characterized by systemic vasculitis and is sometimes complicated by intracranial vasculitis. The incidence of electroencephalographic abnormalities and pleocytosis in the cerebrospinal fluid is higher in patients with Kawasaki disease. However, the reason why febrile convulsions did not occur in the acute phase of Kawasaki disease remains unknown, despite the presence of central nervous system involvement. 相似文献

Recent studies have increased our understanding of the etiopathogenesis of Kawasaki disease (KD). The inflammatory infiltrate in KD coronary artery aneurysms has been shown to consist of CD8 T lymphocytes, macrophages, and IgA plasma cells, consistent with an immune response to an intracellular pathogen with a mucosal portal of entry. The identification of an oligoclonal IgA response in the vascular wall and the detection of a KD-associated antigen in inflamed KD tissues using a synthetic antibody derived from KD oligoclonal IgA antibodies have provided new approaches to identification of the etiologic agent. Highly effective therapy has evolved for KD, even in the absence of identification of the etiologic agent. The existence of incomplete KD cases remains a significant diagnostic dilemma for the clinician. Conclusion: the development of a diagnostic test, more specific therapy, and ultimate prevention of this potentially fatal illness of childhood are dependent upon continued advances in determining the etiopathogenesis of this fascinating disorder.Abbreviations KD Kawasaki disease - IVIG intravenous immunoglobulin 相似文献
