A unique association of Sturge-Weber syndrome and atlanto-occipital assimilation is presented. A 18-year-old male was admitted in emergency because of the sudden severe headache and vomiting. He had vascular nevus in the right half of the face at birth and several episodes of generalized convulsive seizures. On admission craniogram demonstrated calcification in the right occipital area. Neurological examination revealed tenderness in the nuchal region, moderate limitation of cervical mobility in a antero-posterior direction, Bruns-Cushing type nystagmus, bilaterally diminished gag reflex, and positive Romberg's test. Spinal tap showed crystal clear CSF with normal pressure. EEG showed paroxysmal slowing focus in the right parieto-occipital area. Polytomography of the craniovertebral junction demonstrated the unilateral atlanto-occipital assimilation on the left associated with the aplasia of the right posterior arch. Myelography was negative. A right carotid angiography disclosed the dilatation of the basal vein of Rosenthal and abnormal venous vasculature. CT-scan demonstrated the calcified region of the right occipital area more distinctly than the plain roentogenogram, but the enhancement study of the leptomeningeal angioma of the Sturge-Weber syndrome was negative. Never been found this rare association in a review of the literature, the authors discussed the clinical and radiological findings of both diseases.

A case of hypertensive intracerebellar hematoma surgically treated and cured was reported. The 41-year-old male had two cerebrovascular attacks with headache and vomiting followed by left hemiparesis. Drowsiness and dysarthria appeared the next day. The patient was admitted to a hospital, where right facial palsy, loss of right gag reflex and paralytic hemiplegia on the left side were noted. On the 7th day, the patient's consciousness became clear byt the other neurological evidences did not change. On the 14th day, bradycardia and central hyperventilation appeared and he became drowsy again. The patient was transferred to the authors' clinic. When the patient was admitted, he showed typical cerebellar signs such as nystagmus, ataxia, and slurring speech with pyramidal sign on left side and cranial nerves paralysis on right side, and also showed the changes of vital signs as a medullary syndrome in the late stage of the course. The vertebral angiogram revealed a space taking process in the right cerebellar hemisphere. The old blood (30g) was removed by suboccipital craniectomy. The hematoma cavity had a communication with the IVth ventricle through a small perforation in the medial wall of the hematoma. Spontaneour intracerebellar hematoma including of hypertensive origin is not rare in the reports of autopsy but surgically treated case has only rarely been reported. The main reason of few survivals should be in its fulminate course.

A 40-year-old normotensive man suddenly developed dizziness, vomiting, hoarseness and swallowing disturbance. Neurologic examinations showed bilaterally decreased palatal elevation and gag reflex, upbeat nystagmus and gait ataxia. The diagnosis of medullary hemorrhage was first established by computed tomography (CT). Magnetic resonance imaging study further showed a hematoma in the paramedial medulla oblongata extending dorsorostrally to the pontomedullary junction. It gave the precise anatomic boundary of the intramedullary hematoma and was well correlated with the clinical findings. This patient's subsequent prognosis was good with gradual improvement of the clinical signs and symptoms. A follow-up CT scan showed resolution of the hematoma, and the prognosis was consistent with a good neurologic recovery.

We performed a prospective, randomized, double-blind study of 41 children (6-18 years of age) who were undergoing esophagogastroduodenoscopy (EGD) to compare the efficacy of diazepam and midazolam with respect to quality of sedation and amnesia. The endoscopist assessed the patients for control of salivation, gag reflex, vomiting and cooperation after intravenous injection of either 0.1-0.15 mg/kg of midazolam or 0.2-0.4 mg/kg of diazepam. The patients answered a questionnaire at 1 and 24 h after the procedure to assess recall of procedure details, pain and/or discomfort, and their medication choice for future procedures. Vital signs were monitored for 1 h after injection. Although midazolam caused greater mean maximum increase in heart rate than diazepam (30 vs. 14/min), no difference was found between the two treatment groups with respect to other vital signs. There was also no difference in physician's assessment or patient recall of specific events during the procedure. However, significantly fewer patients recalled pain or discomfort with midazolam at both 1 and 24 h following the procedure (p = 0.02). In addition, more patients receiving midazolam indicated preference for the same sedation for future procedures. We conclude that midazolam may provide better amnesia in children undergoing endoscopic procedures.

In a double-blind study, 80 adult patients, undergoing tonsillectomy, were randomly allocated to one of the four groups: d-tubocurarine (d-Tc) 50 micrograms/kg+alfentanil (Alf) 20 micrograms/kg, d-Tc 50 micrograms/kg+Alf 50 micrograms/kg, Alf 10 micrograms/kg+Alf 20 micrograms/kg, Alf 10 micrograms/kg+Alf 50 micrograms/kg. The first drug was given 2 min before thiopental and the second drug 1 min before inserting the mouth gag. Intubation was facilitated with suxamethonium. Anaesthesia was maintained with 70% nitrous oxide in oxygen and peripheral muscle relaxation during operation with vecuronium. For analysis of the induction characteristics, both d-Tc-pretreatment groups were treated together and compared with the results of the Alf-pretreatment groups. Muscle fasciculations occurred in 20% in the d-Tc group and in 70% in the Alf group. Neither d-tubocurarine nor alfentanil prevented the cardiovascular intubation response. Cardiovascular responses to the placement of the mouth gag occurred only in the lower-dose alfentanil groups. ECG changes during operation occurred in 25-45% of the patients. The most common ECG change was junctional rhythm. The operating conditions were good in 65-80% of the patients. The mean recovery score (0-10) ranged from 9.3 to 9.7 between the groups. The incidence of nausea ranged from 20-30% and that of vomiting from 10-25% between the groups. Bleeding from the operation site occurred in 20-30% of the patients. None of the patients needed sutures to stop the bleeding.

Resinferatoxin (100 micrograms/kg, s.c.), the ultrapotent analogue of capsaicin, when given acutely blocked radiation-(200 rads) and copper sulphate (40 mg% 30 ml, p.o.)-induced emesis in ferrets and substantially decreased loperamide (0.5 mg/kg, s.c.)-induced vomiting, without significantly affecting the von Bezold-Jarisch reflex or gag reflex. It also produced a decrease in core temperature as has been reported for capsaicin. The observation that resinferatoxin reduced or blocked emesis induced by both centrally (loperamide) and peripherally (CuSO4, radiation) acting stimuli suggests a novel anti-emetic action that may provide an insight into clinically useful innovative anti-emetics. The mechanism by which resinferatoxin has its anti-emetic effect is at present unknown, although the combination of results from the present study suggest a central site of action involving modulation of release of neurotransmitter, possibly in the nucleus tractus solitarius.

We report a 51-year-old man with mild left central facial palsy and left Avellis' syndrome due to a small medullary infarction. On admission, neurological examination revealed hoarseness, dysphasia, absent left gag reflex, palsies of the left vocal cord and left soft palate, and hypalgesia and thermohypesthesia on the right side of the trunk and extremities. In addition, he had a mild left central facial palsy. He had no nausea, vomiting, vertigo, hiccups, nystagmus, Horner's sign, facial numbness, or paresis or ataxia of the limbs. A T2 weighted MRI showed a small, high signal intensity area in the left dorsal region of the medulla and this lesion was presumed to involve the nucleus ambiguus and a part of the spinothalamic tract. These findings suggest that an aberrant supranuclear pathway, looping around the nucleus ambiguus to the facial nucleus exists in our patient.

The transmission modes of SARS-coronavirus appear to be through droplet spread, close contact and fomites although air borne transmission has not been ruled out. This clearly places dental personnel at risks as they work in close proximity to their patients employing droplet and aerosol generating procedures. Although the principle of universal precautions is widely advocated and followed throughout the dental community, additional precautionary measures - termed standard precaution may be necessary to help control the spread of this highly contagious disease. Patient assessment should include questions on recent travel to SARS infected areas and, contacts of patients, fever and symptoms of respiratory infections. Special management protocols and modified measures that regulate droplet and aerosol contamination in a dental setting have to be introduced and may include the reduction or avoidance of droplet/aerosol generation, the disinfection of the treatment field, application of rubber dam, pre-procedural antiseptic mouthrinse and the dilution and efficient removal of contaminated ambient air. The gag, cough or vomiting reflexes that lead to the generation of aerosols should also be prevented.

Blood specimens from 146 suspected gamma-hydroxybutyrate (GHB) overdose cases, presenting to an emergency department in Washington State over a 12-month period, were analyzed for GHB and other drugs. Of these 146 patients, GHB was confirmed in approximately one-third of the patients (N = 54), sometimes in potentially toxic concentrations. These patients were aged between 17 and 59 years (median 28 years), and 83% were male. Blood GHB concentrations ranged from 29 to 490 mg/L (mean 137 mg/L; median 103 mg/L). In 36 (67%) of the 54 patients, other drugs were additionally detected. Ethanol was measured in 22 (41%) patients, with concentrations ranging from 0.01 to 0.26 g/100 mL (median 0.04 g/100 mL). Other commonly co-administered drugs included 3,4-methylenedioxymethamphetamine, marijuana, methamphetamine, cocaine, and citalopram. Frequently observed clinical symptoms on admission for the GHB overdose group included copious vomiting, ataxia, lack of gag reflex, respiratory depression, mild acute respiratory acidosis, unconsciousness, and sudden altered states of consciousness. Many patients required intubation, and several became combative and required restraints. The majority of patients were discharged within 6 h of hospital admission. However, despite presenting with similar clinical symptoms on admission, GHB was not confirmed in 92 of the 146 overdose patients, suggesting that GHB overdose cases may frequently be indistinguishable from other drug overdoses or medical conditions.

A two-year-old male entire border collie dog was evaluated for a short history of mixed bowel diarrhoea, coughing, vomiting and stranguria. Physical examination revealed dyspnoea with increased ventral lung sounds and a flaccidly distended bladder. Neurological examination revealed poor pupillary light reflexes, an absent gag reflex and a poor anal tone. Thoracic radiography was consistent with megaoesophagus and aspiration pneumonia. Clinicopathological testing revealed an elevated muscular nicotinic acetylcholine receptor antibody titre. The dog was euthanased because of clinical deterioration. Cerebrospinal fluid (CSF) collected immediately post-mortem revealed macrophagic pleocytosis. Post-mortem histopathological examination was consistent with dysautonomia. This is the first report of coexisting autoimmune myasthenia gravis and dysautonomia in a non-human species. The concomitant diseases may suggest a common immunopathological aetiology.
