Male patients with the X-linked lymphoproliferative syndrome (XLP) have an inherited immune deficiency to Epstein-Barr virus (EBV) infection that results in fatal infectious mononucleosis (IM), acquired hypogammaglobulinemia- or agammaglobulinemia, virus-associated hemophagocytic syndrome, and non-Hodgkin's malignant lymphoma (ML). A clinicopathologic analysis of 17 patients with XLP who developed ML was performed. The median age of the patients at the time of diagnosis was 4.0 years (range, 2-19 years). The median overall survival was 12 months (range, 1-216 months). Eight patients had maternally related male relatives with ML. Other phenotypes of XLP were documented in male relatives of the remaining nine patients. Common presenting symptoms were fever, nausea, vomiting, and abdominal pain. Nine patients had "B" symptoms. All ML occurred at extranodal sites. The intestines, most commonly ileocecal, were involved in 76.5% of the cases. Thirteen patients had localized disease (Stages I and II) and four patients had advanced disease (Stages III and IV). A diffuse histologic pattern of growth was observed in all cases. The distribution of histologic subtypes included small noncleaved (41.2%), large noncleaved (17.6%), immunoblastic (17.6%), small cleaved or mixed cell (11.8%), and unclassifiable (5.9%) ML. Surgical resection, radiation therapy, and chemotherapy resulted in disease-free survivals of up to 192 months in eight patients (median 114 months; range, 12-192 months). Eight of 17 patients (47%) are still alive. A median survival of only 6.0 months (range, 1-12 months) was observed in the nine patients who died. No residual ML was found at autopsy. The small noncleaved subtype had an adverse prognosis (seven of nine deaths versus one of eight survivors; P less than 0.05). Bacterial infection was the major cause of death (seven of nine patients). Characteristics that distinguish ML in XLP from other ML include a maternal family history of XLP, early age of onset, acquired hypogammaglobulinemia, post-EBV infection, and ileocecal involvement.

An 8-month-old male infant, previously well, developed acute changes of consciousness associated with high fever, vomiting, and respiratory failure. Brain CT showed hypodensity of the brainstem, which had shown hyperechogenicity on brain ultrasonography. Brainstem encephalitis caused by Epstein-Barr virus (EBV) was diagnosed, based on the clinical presentation, neuroimaging and paired serological examinations. The patient expired eventually due to central failure. We suggest that EBV infection should be a differential diagnosis in cases of brainstem encephalitis.

Following a febrile illness with nasal discharge and vomiting a 1.5-year-old girl developed monomorphous erythematous papular lesions on the face, buttocks and extremities. A diagnosis of Gianotti-Crosti syndrome on the basis of an Epstein-Barr virus infection was made. The patient recovered in eight weeks without treatment. In the Netherlands the originally described relationship with a hepatitis B infection is very improbable in patients with the Gianotti-Crosti syndrome. Other viral agents like Epstein-Barr virus are much more likely.

A 7-year-old boy presented with headache, vomiting, fever, epileptic seizure, and a left hemiparesis. Computed tomography revealed low-density areas in the left frontal lobe and right occipital lobe. Incisional biopsy of the right occipital lesion showed a diffuse and laminar destruction accompanied by microglial reaction in the cortex. An encephalitis of unknown etiology was suspected without data on viral titers in the serum and cerebrospinal fluid. Two months later right hemiparesis and ataxia appeared that were alleviated by prednisolone. Thereafter, similar symptoms repeatedly appeared, but disappeared after treatment with prednisolone. Approximately 5 years later, hemiparesis recurred: computed tomography revealed an 8 x 5 cm mass in the right lobe. A brain biopsy revealed non-Hodgkin's lymphoma of diffuse large, predominantly non-cleaved cell type of B-cell nature. The patient died 1 week after the surgery. The first biopsy specimen (taken at 7 years of age) did not contain Epstein-Barr virus genomes even when examined by polymerase chain reaction. The polymerase chain reaction and in situ hybridization techniques on the second biopsy specimens (taken at 12 years of age) revealed the Epstein-Barr virus sequences in the nuclei of diffuse large cell lymphoma. These findings suggested that the Epstein-Barr virus infection occurring between the first and second biopsies played an etiologic role in the pathogenesis of the brain lymphoma.

A 19 year-old man presented with pharyngitis and cervical lymphadenopathy, followed by vomiting and acute cerebellar ataxia. Serologic studies were consistent with a recent Epstein-Barr virus infection. Although contrast-enhanced brain computed tomography and MRI scans were normal, brain perfusion single photon emission tomography (SPECT) examination using 99mTc-HMPAO, performed on the 15th day of illness, showed marked cerebellar hyperperfusion, suggesting a diagnosis of acute post-infectious cerebellitis. After treatment with intravenous human immunoglobulin (IVIg, 2 g kg-1 over three days), progressive neurologic improvement occurred over two weeks. A brain SPECT study repeated after two additional weeks demonstrated a normal perfusion pattern. We conclude that brain perfusion SPECT examination is useful in identifying post-infectious cerebellitis and in monitoring its clinical course. In addition, IVIg may be helpful in treating this condition.

Fifty cases of postinfectious encephalomyelitis admitted to our Pediatric Department during the period 1980 to 1997 were consecutively collected and reviewed. There were 28 males and 22 females. The age of onset ranged from 9 months to 14 years. The antecedent infections included measles (6 cases), rubella (5 cases), mumps (4 cases), chicken pox (4 cases), Epstein-Barr virus infection (11 cases), mycoplasma infection (6 cases), and unknown etiology (14 cases). The cessation of measles, rubella, and mumps as causes for encephalomyelitis in our patients corresponds with the introduction of a measles-mumps-rubella nationwide vaccination program in Taiwan commencing in 1992. The main clinical symptoms were fever, headache, and/or vomiting, seizure, and motor weakness. The presenting signs included altered consciousness, meningeal signs, cranial nerve palsy, brainstem signs, involuntary movement, and cerebellar signs. Computed tomography scans were abnormal for 14 (56%) of 25 patients studied, whereas magnetic resonance imaging (MRI) disclosed lesions in 14 (82%) of 17 patients, with abnormal signals in various parts of the cerebral hemisphere, as well as in the basal ganglion, diencephalon, midbrain, brain stem, and cerebellum. Of the three patients with negative MRI findings, an abnormal finding on somatosensory evoked potential was noted for one patient, and a focal decrease in tracer uptake on single photon emission computed tomography (SPECT) was found for the other two patients. This study demonstrates that the causative agents of postinfectious encephalomyelitis in Taiwan have changed from those of traditional exanthematous diseases to nonspecific respiratory infections and suggests that this may also be the case in other parts of the world. MRI remains the imaging method of choice, whereas other neurofunctional studies such as evoked potentials and SPECT are complementary for the diagnosis.

Acute hepatic failure has been reported in the presence of Epstein-Barr virus (EBV) infection. Autoimmune hemolytic anemia may also occur in the course of this infection. We report a rare case of fulminant hepatic failure and autoimmune hemolytic anemia associated with Epstein-Barr virus. A seven-year-old girl was admitted with the complaints of abdominal pain, vomiting and jaundice. She was irritable, confused and had mild hepatomegaly with marked splenomegaly. Serum aminotransferase levels were moderately elevated, while direct and indirect bilirubin levels were markedly elevated. Prothrombin time was prolonged. Hemoglobin was 3.9 g/dl. Anti-HAV IgM, HbsAg, anti-HBc IgM, anti-HCV and anti-CMV IgM were negative, while IgM VCA EBV, IgG VCA EBV and anti-CMV IgG were positive. Serum copper and ceruloplasmin levels were normal. The patient received supportive therapy for hepatic failure. Meanwhile, the cause of the deep anemia was investigated and autoimmune hemolytic anemia was ascertained by means of increased reticulocyte count and positive Coombs test. Corticosteroid therapy was administered. The prognosis was good. Although not reported before, the combination of acute hepatic failure and autoimmune hemolytic anemia may complicate the course of EBV infection. Physicians need to be aware of this association.

Rheumatoid arthritis (RA) is an autoimmune disease associated with altered immunoregulation and resulting in a deforming polyarthritis. Methotrexate (MTX) is a commonly used second line agent for RA, and there have been several recent reports of Epstein-Barr virus (EBV)-associated polyclonal B cell lymphoproliferative disorder in MTX-treated RA patients. The patient in this report had long standing RA treated with MTX and had recently begun taking a cyclooxygenase-2 (COX-2) inhibitor. She developed a febrile illness associated with severe pancytopenia and leukocytoclastic vasculitic rash followed by diffuse adenopathy, with serologic and pathologic evidence of EBV infection. Previous studies have demonstrated the interaction of MTX and a variety of non-steroidal, anti-inflammatory drugs (NSAIDs) with various clinical manifestations including acute renal failure, pancytopenia, vomiting, diarrhea, elevated liver transaminases, jaundice, mucosal ulcerations, and pyrexia. However, we have not identified previous reports suggesting interaction between MTX and COX-2 inhibitors. We hypothesize that decreased renal elimination of MTX induced by the COX-2 inhibitor resulted in enhanced hematopoietic toxicity and immunosuppression causing the EBV-associated lymphoproliferative disease.

A 10-year-old boy presented with fever, headache, vomiting, and hypersomnolence. An akinetic-rigid syndrome with tremor, dysphagia, dysphonia, and sialorrhea, as well as pyramidal signs, developed. Slightly elevated protein content was found in the cerebrospinal fluid and serological investigations were suggestive of a primary Epstein-Barr virus infection. Magnetic resonance imaging (MRI) showed massive bilateral hyperintense striatal and punctiform periventricular lesions. After 2-month treatment with steroids and antiparkinsonian drugs, all features resolved without sequelae. Control MRI demonstrated only minimal residual lesions in both putamina. Strongly resembling the encephalitis lethargica-like syndrome, this case is an unusual presentation of parainfectious acute disseminated encephalitis.

Sevoflurane, a halogenated anesthetic, is associated with mild aminotransferase elevations but does not tend to cause clinically significant hepatotoxicity. We report a rare case of severe hepatic necrosis following exposure to sevoflurane during surgery. A 37-year-old man presented with nausea,vomiting, abdominal pain, and jaundice on the third postoperative day after an abdominal wall mass resection. Laboratory tests showed markedly elevated aminotransferase levels, hyperbilirubinemia, and coagulopathy. His viral hepatitis and human immunodeficiency virus (HIV) serologies were negative for acute infection, and his Epstein-Barr virus (EBV) and cytomegalovirus (CMV) serologies were suggestive of recent EBV infection and remote CMV infection. Antinuclear antibody and anti-smooth muscle antibody screens were negative. Ceruloplasmin and serum copper values were in the normal range. The histopathological findings included an acute centrilobular cholestatic hepatocellular injury compatible with the clinical history of acute drug-induced hepatotoxicity. The patient improved with conservative management. Unlike other halogenated anesthetics, proposed mechanisms of sevoflurane hepatotoxicity include production of compound A, increased cytosolic free Ca(2+), and activation of free radical metabolizing enzymes. The patient was likely susceptible to toxicity due to an underlying EBV infection and a probable history of exposure to halogenated anesthetics. Sevoflurane is generally considered to be relatively safe for subjects with mild liver dysfunction, in comparison with other halogenated anesthetics. However, this case suggests that sevoflurane can lead to severe life-threatening hepatic necrosis in at-risk individuals.
