It is known that rotavirus gastroenteritis can accompany some neurological manifestations, including encephalitis/encephalopathy or seizures. However, the detailed pathogenesis involved has not been fully understood. To date, acute cerebellitis associated rotavirus gastroenteritis has not been previously reported, except for one case. Herein, we describe two cases of acute encephalitis/encephalopathy and concurrent cerebellitis, associated rotavirus gastroenteritis. Following vomiting and diarrhea, case 1 experienced convulsions and consciousness disturbance and case 2, transient loss of consciousness with eye deviation. After these symptoms subsided, cerebellar signs became evident and a brain MRI showed cerebellar involvement in both cases. Both cases showed speech disturbances, such as mutism, slow speech and dysarthria. In this report, we will discuss the possible pathogenesis of rotavirus associated acute encephalitis/encephalopathy and concurrent cerebellitis.

We reported a case of pontine infarction presenting with conjugate deviation and unilateral conjugate gaze palsy. A 75-year-old man was admitted to our hospital because of vomiting. On the day of admission, his neurological findings showed only conjugate deviation to the right without consciousness disturbance, hemispatial neglect, and hemiparesis. On day 5 after admission, the conjugate deviation to the right disappeared, but he could not gaze left with either of his eyes. The pathological lesions, therefore, were considered to be a unilateral paramedian pontine reticular formation (PPRF) and abducens nucleus. Diffusion-weighted imaging (DWI) on day 2 revealed a small high intensity lesion in the left paramedian pontine tegmentum. A diagnosis of brain infarction was made. A Holter electrocardiogram and electroencephalogram were normal. Transesophageal echocardiography disclosed ulcerated plaque in the aortic arch. This is the first case of pontine infarction presenting with conjugate deviation in which unilateral conjugate gaze palsy and DWI could confirm the pathological lesion.

Reversible posterior encephalopathy syndrome (RPES) is a clinical entity characterized with headache, nausea, vomiting, seizures, consciousness disturbance, and frequently visual disorders associated with neuroradiological findings, predominantly white matter abnormalities of the parieto-occipital lobes. The central nervous system manifestations of systemic lupus erythematosus (SLE) are highly diverse. However, SLE-associated RPES has been seldom reported. Here, we report a case with RPES in SLE and lupus nephritis with exclusive involvement of parietal and occipital cortices. A systematic review of the literature on the pathogenesis and treatment of SLE-associated RPES is included.

Valproate-induced hyperammonemic encephalopathy is an unusual but serious complication that may occur in people with normal liver-associated enzyme levels, despite normal therapeutic doses and serum levels of valproate. Here, we describe an adolescent girl who had absence seizure and complained about progressive dizziness and general malaise several days after restarting valproate. Then, she presented vomiting and decreased consciousness three weeks after valproate use. Notably, her serum ammonia level was five times the upper limit of normal (184 micrommol/L), with normal liver-associated enzyme and supra-therapeutic valproate level. EEG showed continuous generalized slowing. The tandem mass analysis revealed carnitine deficiency. Consciousness improved after emergent hemodialysis. Ammonia level and EEG also returned to normal. Possible mechanisms, risk factors and the treatments of valproate-induced hyperammonemic encephalopathy are described. Physicians should consider this possibility when consciousness disturbance occurs in patients treated with valproate.

Acetamiprid belongs to a new class of insecticides called neonicotinoids, which have different effects from other insecticides. Neonicotinoids act as selective agonists at the nicotinic acetylcholine receptors, therefore their toxicity is higher to insect pests than to humans. Cases of acetamiprid poisoning are still rare, because neonicotinoids have been released in the market only within the last decade. We experienced a case of acute acetamiprid poisoning and measured the blood concentration of acetamiprid. A 79-year-old man had ingested acetamiprid and got medical attention two hours after ingestion. On arrival, he had consciousness disturbance (GCS-8), hypotension, nausea, vomiting and hyperglycemia, but had no constricted pupils nor mucous supersecretion which are characteristic in organophosphate poisoning. Gastric lavage was performed and activated charcoal and laxative were administered. Paroxysmal atrial fibrillation persisted until 11 hours after ingestion. The next day, his symptoms with regards to the effects of acetamiprid improved and he was discharged from the hospital without complication. Blood concentration of acetamiprid on arrival, approximately 2 hours after the ingestion, was 21.1 microg/ml.

Valproate-induced hyperammonemic encephalopathy is an unusual but serious complication that can occur in people with normal liver-associated enzyme levels, and despite normal therapeutic doses and serum levels of valproate. Here, we describe an adolescent girl suffering from absence seizures, who complained of progressive dizziness and general malaise several days after restarting valproate. She developed vomiting and decreased consciousness after 3 weeks of valproate use. She had a serum ammonia level five times higher than the upper normal limit, normal liver-associated enzymes, and a supra-therapeutic valproate level. Electroencephalography (EEG) showed continuous generalized slowing. Tandem mass spectrometry analysis revealed carnitine deficiency. Her consciousness improved after emergent hemodialysis. Her ammonia level and EEG also became normal. Possible mechanisms, risk factors and treatments of valproate-induced hyperammonemic encephalopathy are described. Physicians should consider this possibility when consciousness disturbance occurs in patients treated with valproate.

Two patients presented with metastatic pineal tumors. A 69-year-old man had gait disturbance, dementia, and urinary incontinence but no history of previous malignancy. Magnetic resonance imaging of the brain revealed a 23-mm tumor in the pineal region and obstructive hydrocephalus. A 37-year-old man had been treated for thyroid cancer. He presented with vomiting and consciousness disturbance. Brain magnetic resonance imaging revealed a 28-mm pineal tumor associated with intratumoral hemorrhage and accompanying obstructive hydrocephalus. Both patients underwent neuroendoscopic biopsy and third ventriculostomy through the foramen of Monro, resulting in reliable histological diagnoses and subsidence of hydrocephalus.

Glyphosate-surfactant (GlySH) is a commonly used herbicide that has been used in attempted suicide. Most reports of GlySH toxicity in patients have followed ingestion of the commercial product "Round-up" (Monsanto Ltd; Melbourne, Victoria, Australia), which consists of a mixture of glyphosate (as a isopropylanine salt) and a surfactant (polyoxyethyleneamine). Ingestion of Round-up is reported to cause significant toxicity including nausea, vomiting, oral and abdominal pain. Renal and hepatic impairment and pulmonary oedema may also occur. Impaired consciousness and encephalopathy have been reported as sequelae but there are limited data on the central nervous system (CNS) effects of Round-up toxicity. We report a 71-year-old male who attempted suicide with GlySH and developed a prolonged but reversible encephalopathy suggestive of acute CNS toxicity.

A 42-year-old Indian man received 450 mg rifampicin (RIF) and 150 mg isoniazid (INH) daily after being diagnosed of a latent tuberculosis infection. Baseline serum aminotransferase and total bilirubin levels were within normal limits. On day 31 of treatment, the patient experienced epigastric discomfort and general malaise and one week later he developed nausea and episodic vomiting. The patient missed his first scheduled clinic appointment and he continued taking RIF-INH despite his symptoms. He visited the tuberculosis clinic on day 47 of treatment where he was found to be jaundiced and his liver enzymes were elevated. RIF-INH was stopped and the patient was admitted to our hospital as a case of RIF-INH induced hepatitis. On the 7th day of hospitalization, the patient developed consciousness disturbance with flapping tremor and high ammonia level. The patient was diagnosed with fulminant hepatic failure and transferred immediately to the medical intensive care unit, where he died 4 days later.

A 36-year-old female patient was admitted to our hospital with a rare case of aneurysm at the origin of the accessory middle cerebral artery (MCA) manifesting as severe headache and vomiting. Neurological examination did not detect any abnormalities or consciousness disturbance. Computed tomography demonstrated diffuse subarachnoid hemorrhage. Magnetic resonance angiography showed an aneurysm in the horizontal portion of the left anterior cerebral artery (A(1)). Digital subtraction angiography and three-dimensional digital subtraction angiography demonstrated a saccular aneurysm originating at the junction of the left A(1) and accessory MCA. Another accessory MCA originated at the proximal portion of the left A(2) without an aneurysm. Two accessory MCAs were found on the left. Neck clipping was performed via a left pterional approach. One month after admission, she was discharged without neurological deficits.
