A 9-year-old female was admitted to our hospital due to a generalized seizure and consciousness disturbance. The patient had a fever and rash four days before admission, but she had no respiratory symptoms. The seizure and consciousness disturbance was prolonged and intractable. We diagnosed the patient as having encephalitis because of the increase in the cell count in the cerebrospinal fluid (CSF) and a diffuse slow EEG wave. The computed tomography of the head was normal. The causative agent was identified as Mycoplasma pneumoniae because of the increase of antibodies, and the detection of a specific DNA with a polymerase chain reaction. The interleukin (IL)-6 level of CSF was high (384 pg/ml). In spite of intensive treatment she had severe neurological sequelae. The invasion of Mycoplasma pneumoniae to the central nervous system appeared to have a role in the development of encephalitis in the patient. We speculated that there is a possible relationship between the IL-6 levels of CSF and clinical severity of encephalitis.

We studied seizures that occur during the acute phase of aseptic and bacterial meningitis in childhood. Of the 108 children with aseptic meningitis, five had seizures (4.7%). Four patients developed them within 24 hours of the onset of the initial symptom (fever in 3 cases), and three had repeated seizures on the first day. One case had SIADH complication, but another neurologic abnormalities were not observed. On the 18 children with bacterial meningitis, three cases (16.7%) had seizure, which occurred on the second day of illness. Disturbance of consciousness and cerebral hypertension were observed in 2 cases each, and abnormal cerebral CT findings in all the three. The NSE level in the cerebrospinal fluid was elevated in 2 cases. Thus, seizures occurring in the acute phase of aseptic meningitis may reflect transient cerebral functional abnormality accompanying fever or SIADH, whereas those in bacterial meningitis may result from neural tissue damage due to encephalopathy or angitis. In aseptic and bacterial meningitis, the presence of seizures in the acute phase was not correlated with the neurological outcome.

We reported a 10-year-old boy with an interhemispheric subdural empyema caused by acute excerbation of frontal sinusitis. He has suffered from allergic rhinitis and pansinusitis for years. He had fever and a generalized tonic-conic seizure, followed by prolonged consciousness disturbance and right hemiparesis. CT and MRI were useful to diagnose an interhemispheric subdural empyema, which showed a characteristic double-layer fluid collection pattern. Prompt diagnosis and treatment with craniotomy resulted in recovery without any neurological sequelae. His basic disorders, allergic rhinitis and pansinusitis, were successfully treated with macrolides and antiallergic drugs: pranlukast hydrate and sodium cromoglicate, administered per os and by inhalation, respectively.

Clinical outcome of dialysis patients after eating star fruit (Averrhoa carambola) varies, but it may be fatal. In the past 10 years, 20 such patients were treated in our hospital when they developed clinical symptoms after eating the fruit or drinking star fruit juice. Their initial presentations included sudden-onset limb numbness, muscle weakness, intractable hiccups, consciousness disturbance of various degrees, and seizure. No other major events that might be responsible for these symptoms could be identified. Eight patients died, including one patient with a serum creatinine level of 6.4 mg/dL who had not yet begun dialysis. The clinical manifestations of the survivors were similar to those who died except for consciousness disturbance and seizure. Death occurred within 5 days despite emergent hemodialysis and intensive medical care. The survivors' symptoms usually became less severe after supportive treatment, and these patients subsequently recovered without obvious sequelae. The purpose of this article is to report that patients with renal failure who ingest star fruit may develop neurological symptoms and also run the risk for death in severe cases. Mortality may also occur in patients with chronic renal failure not yet undergoing dialysis.

Cyclosporine (CSP) is the most frequently used immunosuppressive agent for prevention of graft versus host disease (GVHD) in allogeneic bone marrow transplantation (BMT). Some adverse effects such as hepatic and renal toxicity have been frequently encountered, but central nervous system (CNS) toxicity caused by CSP is rare. We report an adult male patient with acute myeloid leukemia who developed CSP-induced encephalopathy under treatment for allogeneic BMT from an unrelated donor. Methotrexate and CSP were used for GVHD prophylaxis. Leukocyte and platelet engraftment were successfully achieved on days 21 and 24 after BMT, respectively. Abrupt onset of mental confusion and disorientation occurred on day 25, followed by a generalized tonic clonic seizure and consciousness disturbance. The whole blood CSP level was 160.65 ng/mL. Magnetic resonance (MR) imaging revealed high signal intensities in the bilateral occipital lobes with predominant involvement of the cortical areas. The patient recovered from the CNS toxicity, but with slight memory impairment, 6 days after CSP was discontinued. When patients receiving CSP treatment for allogeneic BMT develop mental confusion, consciousness disturbance, or seizure, CSP-induced CNS toxicity should be taken into consideration.

Partial complex seizures are relatively frequent type of epileptic seizures. These attacks are having aura in 60% of cases, that can be vegetative, motor, sensor or psychological one. Important is aura in the form of uncinatus seizures (unpleasant odor), because we must exclude tumor of temporal region in these patients. Altered consciousness comes after aura, patient has opened eyes, face can be pale or red, and automatism appear, in the form of different movements. These automatisms are often considered insignificant by parents or eyewitnesses. There is often misdiagnosis of this type of seizures, because only about 20% of standard EEG recordings find specific epileptic grapho-elements. Therapy of these seizures is difficult, with the success in only 50% of cases. Ictal automatisms were tested in the group of 36 children with partial complex seizures aged 4 to 17 years. Duration of epilepsy was 1 to 5 years. All patients had proved diagnosis of partial complex seizures, clinically and on electroencephalography, CT scan and MRI in medically intractable seizures. Eleven patients were videotaped during the attack. All patients had questionnaire filled by parents, about automatisms. Thirty-four patients (94.4%) had ictal automatisms, and 2 with epileptic focus in frontal region did not. Some patients had different types of automatisms. Most frequent ones were mimicking (15.19%), sitting-standing up (10.76%), swinging (8.23%), swallowing (7.59%) etc. It can be concluded that automatisms are almost obligatory part of partial complex seizure, and their registration is essential for correct diagnosis and treatment of these seizures.

Nitrofen has been banned in Taiwan since January 1, 1983 due to its tetrogenicity. A 78-y-o female consumed about 500 ml of herbicide, labeled as nitrofen, in a suicide attempt. Consciousness disturbance occurred immediately. After 9 h, bloody-tarry stool was noted. Hematemesis occurred 19 h later. Hepatotoxicity and nephrotoxicity also developed. Twitching of head and both upper extremities lasting 20-30 sec and up to 5 min developed on day 3. Sometimes an upward gaze with the face turned to the right or a convulsion of the right upper extremity was observed. EEG showed alpha coma, generalized slow spike-and-wave complexes, and isolated generalized sharp waves mainly in the left occipital area. On day 7, endotracheal intubation was performed due to apnea; she expired on day 9. The pesticide was found to contain butachlor and chlornitrofen. The Agricultural Committee prohibited the marketing of chlornitrofen due to its generation of tumors in animals. The combination of butachlor and chlornitrofen can result in consciousness disturbance, leucocytosis, gastrointestinal hemorrhage, rhabdomyolysis, hypocalcemia, hypoalbuminemia, elevated amylase, nephrotoxicity, hepatotoxicity, seizures and death. The cytotoxicity of butachlor may be related to the patient's death. Active components of pesticides should be checked if the clinical course of a poisoned patient is unusual to allow appropriate interventions.

We reported a 15-year-old boy with an acute myelomonocytic leukemia and FK 506-induced leukoencephalopathy. He was received FK 506 for graft versus host disease occurred after peripheral blood stem cell transplantation. He, four weeks later, had generalized seizures and consciousness disturbance. The serum level of FK 506 was high (27.5 ng/ml). His brain MRI showed abnormal high intensity areas in the frontal and parietal white matter lesions on T2-weighted images. Neuropathological studies revealed the destruction of myelin sheeths and axons in the cerebral white matter corresponded with abnormal lesions on MRI. There were calcification and mineralization in the small vessel walls of the cortex and white matter. Osteopontin immunoreactivity was detected in the endothelial cells of small vessels. These findings suggest that the vascular damage was involved in the FK 506-induced leukoencephalopathy.

We reported a 37-year-old man who presented complex partial status epilepticus as the initial symptom of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS). He showed fluctuating consciousness disturbance, left homonymous hemianopsia, and paroxysmal conjugated eye deviation to the left. The lactic acid level was elevated in blood and CSF, and ragged-red fibers were observed in the biopsied muscle. MRI demonstrated T2-prolonged lesions in the right occipito-parieto-temporal lobes. Since a mutation of mitochondrial DNA (A3243G) was identified, he was diagnosed as having MELAS. On an ictal record, high amplitude, rhythmic sharp waves were observed at right parieto-temporo-occipital region. High amplitude slow waves were also observed on the right hemisphere, especially in the right frontal lobe. These ictal discharges gradually decreased at their amplitude and in frequency, and then ictal EEG turned to the interictal EEG. During an ictal period, conjugated eye deviation to the left side and consciousness loss were observed. These seizures were observed once every several minutes. During the interictal period, sharp waves and sharp-wave complexes were observed frequently at right parietal and posterior temporal lobes. The venous injection of diazepam (10 mg) normalized EEG quickly. When consciousness loss, especially fluctuating, was observed in the patients of MELAS, complex partial status epilepticus should be considered.

A 59-year-old man, who was diagnosed as having Parkinson's disease and depression seven years ago and was on oral antiparkinsonian agents, antianxiety agents, and antidepressants, developed a high fever, disturbed consciousness, and marked muscle rigidity after discontinuation of etizolam and amitriptyline. He was admitted to a nearby hospital. Hypothyroidism had been noted two months before admission. Marked muscle rigidity and increased serum CK were observed. Since discontinuation of benzodiazepine has been known to rarely trigger a neuroleptic malignant syndrome (NMS), he was diagnosed as having NMS. After receiving dantrolene and bromocriptine, these symptoms temporarily improved but he again developed consciousness disturbance, and convulsive seizures associated with an elevated serum CK. He was transferred to our hospital. On admission, the CK level was normal at 168 IU/l, while free T4 was 0.6 ng/dl (normal range, 0.9-2.3) and TSH was 108.7 mU/ml (normal range, 0.2-4.2) in serum, indicating the presence of primary hypothyroidism. As an increase in thyroid hormone dosage improved the thyroid function to normal level, his disturbed consciousness and muscle rigidity gradually improved. Convulsive seizure and recurrence of NMS in a short interval are unusual in neuroleptic malignant syndrome. In this patient, hypothyroidism may have contributed to the development of malignant syndrome through metabolic changes of the central dopaminergic system, and discontinuation of etizolam, a kind of benzodiazepine, may have triggered NMS, since there has not been reported that discontinuation of antidepressants including amitriptyline triggers NMS.
