Infantile spasms in an infant with cytomegalovirus infection treated with ganciclovir

A 3-month-old male infant with cytomegalovirus infection and intractable partial seizures was treated with ganciclovir for 6 weeks. The drug was well tolerated, and virus shedding in the cerebrospinal fluid and urine was eliminated, although infantile spasms at the age of 6 months appeared. At the age of 12 months, intractable seizures persisted, and the psychomotor development of the infant was markedly delayed. To our knowledge, no previous similar case has been reported. These findings suggest that treatment with ganciclovir of infants with cytomegalovirus infection results only in cessation of virus shedding in the cerebrospinal fluid and urine without having a preventive effect on the future appearance of infantile spasms. This may be due to the irreversibility of previous brain damage from the cytomegalovirus infection and the virostatic nature of the drug

Long-term findings on brain magnetic resonance imaging in acute encephalopathy with bilateral striatal necrosis associated with measles

The long-term findings on brain magnetic resonance imaging (MRI) in a 7 10/12-year-old boy with a history of acute encephalopathy with bilateral striatal necrosis following measles at the age of 22 months are described. At the early stage of illness, brain MRI studies revealed bilateral, symmetric basal ganglia lesions, predominant on the globi pallidi, appearing as hyperintense signals on T-1- and T-2 weighted images. Six years later, follow-up brain MRI studies showed that the bilateral, symmetric lesions on the globi pallidi persisted with low signal on T-1- and high signal on T-2 weighted images. At present, the patient has some persistent neurologic signs. These findings suggest that both clinical and neuroradiologic findings may persist in children with acute encephalopathy with bilateral striatal necrosis following measles

Acute necrotizing encephalopathy associated with parainfluenza virus in a Caucasian child

Acute necrotizing encephalopathy is a severe parainfectious disorder with a clear racial predilection for Oriental children living in the Far East. The prognosis was originally reported as grave; however, a mild form of the disease has recently been described. A case of parainfluenza virus-associated acute necrotizing encephalopathy in a Caucasian child with a mild clinical course and excellent prognosis is presented. In this patient, the initial clinical picture was not very impressive, and the diagnosis was delayed until the third week of the illness, when neuroimaging was performed. Two months later, clinical and neuroimaging findings had almost completely resolved. Suggested criteria for a benign prognosis, such as normal liver function and cerebrospinal fluid protein levels, asymmetric thalamic lesions, and no brainstem involvement, were relevant in the present case. An extended diagnostic work-up for metabolic, vascular, coagulation, and infectious diseases was negative apart from a seroconversion for parainfluenza virus. To our knowledge, this is the first reported case of acute necrotizing encephalopathy associated with parainfluenza virus infection. Acute necrotizing encephalopathy, especially in the mild form, might not be fully recognized and could be underdiagnosed in Europe, where the reported incidence of the syndrome is very low

Serum amylase, pancreatic amylase and lipase concentrations in epileptic children treated with carbamazepine monotherapy

Background: Serum total amylase and lipase activities have been determined in epileptic patients treated with polytherapy using enzyme-inducing anticonvulsant drugs; however, to our knowledge, serum total amylase, pancreatic amylase and lipase activities have not previously been determined in patients receiving carbamazepine monotherapy. The purpose of this study was to investigate by a prospective, self-controlled method, whether early treatment with carbamazepine monotherapy may alter serum total amylase, pancreatic amylase and lipase concentrations of epileptic children. Methods: Serum total amylase, pancreatic amylase and lipase activities have been determined in 18 epileptic children before and at 6 and 12 months of treatment with carbamazepine monotherapy. Serum gamma-glutamyltransferase activities were also determined. Results: Serum total amylase concentrations were significantly increased at 6 months of treatment (p=0.034), and serum nonpancreatic amylase concentrations were significantly increased at 6 (p=0.016) and 12 months of treatment (p=0.039), whereas serum pancreatic amylase and lipase concentrations did not significantly change at 6 or 12 months of treatment with carbamazepine monotherapy. Furthermore, serum gamma-glutamyltransferase concentrations were significantly increased at 6 (p=0.000) and 12 months of treatment (p=0.000) with carbamazepine monotherapy. There was no significant correlation between serum nonpancreatic amylase concentrations and serum gamma-glutamyltransferase or carbamazepine concentrations at 6 and 12 months of treatment with carbamazepine monotherapy. Conclusions: These findings indicate that nonpancreatic amylase concentrations may be increased in patients treated with carbamazepine monotherapy. Therefore, measurement of serum pancreatic amylase and lipase concentrations is suggested in epileptic patients receiving carbamazepine monotherapy with symptoms suggesting pancreatic dysfunction, so that unnecessary discontinuing of treatment with carbamazepine should be avoided.
