Carbon dioxide is the fourth most abundant gas in the earth's atmosphere, and it is widely used in the chemical industry. Solid carbon dioxide is commonly known as dry ice. At low concentration, carbon dioxide appears to have little toxicological effect. At higher concentrations, however, it can produce an increased respiratory rate, tachycardia, cardiac arrhythmia, loss of consciousness, convulsion, and even death. Management of carbon dioxide poisoning requires the immediate removal of an individual from the toxic environment and administration of oxygen. It is important to know the concentration of carbon dioxide to which a patient has been exposed. We report a case of acute poisoning from solid carbon dioxide in a patient presenting with drowsiness and diminished mental capacity when she arrived in the emergency department. She recovered completely after administration of oxygen with conservative treatment.

It is common m childhood that children suffer intracavity or head injury, falling down backward, having chopsticks in their mouth. But most of them have paralysis of upper and lower extremity because of secondary damage by penetrating injury of brainstem and spine. We could not find this case which have shown infaction of medulla oblangata on MRI and paralysis by impact only without clear penetrating evidence. So the authors report this case with study of literature because we experience one case that have high signal density in brainstem on MRI, Loss of consciousness, and left hemiplegia without clear penetrating evidence after falling down backward, having chopsticks in her mouth and regard it rare case.

Few preoperative extrapontine myelinolysis (EPM) cases with pituitary adenoma have been reported. No such case had long follow-up to see the outcome of EPM. We reported a 38-year-old man complaining of nausea, malaise and transient loss of consciousness who was found to have severe hyponatremia. Neurologic deficits including altered mental status, behavioral disturbances, dysarthria and dysphagia developed despite slow correction of hyponatremia. Endocrine and imaging studies revealed hypopituitarism, nonfunctional pituitary macroadenoma and extrapontine myelinolysis. Transsphenoidal surgery was performed after three weeks of supportive therapy, when neurological symptoms improved significantly. The patient recovered function completely 3 months after surgery. Our case indicates that outcome of EPM can be good even with prolonged periods of severe neurologic impairment.

We studied the factors that would affect the severity of psychiatric symptoms of the Sampoong accident survivors. In this study, the analyzed factors are sex, age, marital status, educational level, loss of consciousness, witness of death, death of related person, duration until the rescue, duration of hospitalization, and psychiatric treatment after the accident. Although our study has some limitations, we found some factors that affect the severity of psychiatric symptoms after the severe traumatic accident.

Choroid plexus carcinomas are extremely rare in adults. They can behave aggressively and their optimal management is uncertain. A 35-year-old woman was admitted with an episode of loss of consciousness. Magnetic resonance imaging showed a homogeneously enhancing mass in the trigone of the right lateral ventricle. Detailed examinations found no evidence of an extraneural primary focus. She underwent total removal of the tumor. Pathological diagnosis was confirmed as a choroid plexus carcinoma. She is doing well eight months after surgery.

Cerebral air embolism combined with cardiomyopathy secondary to pulmonary barotrauma is rare. Here, we report an unusual case of cerebral air embolism combined with transient cardiomyopathy secondary to large bulla rupture during a pulmonary function test after lung cancer surgery. The patient experienced loss of consciousness. Computed tomography and magnetic resonance imaging suggested a cerebral air embolism. Electrocardiography showed ST-segment elevation and abnormally high plasma levels of cardiac enzymes. Echocardiography and coronary angiography suggested cardiomyopathy. The patient was discharged with no sequelae.

Syncope is defined as a transient loss of consciousness and postural tone, characterized by rapid onset, short duration, and spontaneous recovery. Stellate ganglion block (SGB) is a nerve block method that is used for treatment of neuropathic pain in the head, neck and upper extremities, especially trigeminal neuralgia, postherpetic neuralgia and complex regional pain syndrome. SGB can modulate and stabilize the sympathetic nervous system, which prevents it from overexcitation and improves symptoms of syncope. The authors report a patient who was treated for pain and edema of both upper extremities with SGB, then showed improvement in recurrent syncope followed by chest pain and overall quality of life.

Single subcutaneous injection to SD rats of both sexes was performed to investigate the acute toxicity of new skin allergy-remedy ointment, Banaron. Banaron is composed of lidocaine hydrochloride, chloro-pheniramine maleate, prednisolone acetate, chlorohexidine hydrochloride, methyl salicylate, 1-menthol and d-camphor. The results were as fellows. $LD_{50}$, /TEX> values of Banaron were 8373.6 mg/kg for male and 8260.1 mg/kg for females. Death occurred within 24 hours after administration at doses up to 6600 mg/kg. The main cause of deaths seemed to be respiratory disturbance. General symptoms decreased of activity and respiratory rate, salivation, tremor and loss of consciousness which were commonly observed by some survived animals and all dead animals. No significant gross findings of internal organs and body weight changes in treatment groups in comparison with these of control group were observed at the maximum dose levels in Banaron.

Stellate ganglion block(SGB) is frequently performed to relieve a patient from headache of various. We experienced a rare case of subarachnoid hemorrhage by aneurysmal rupture after SGB. A 46-year-old female patient diagnosed with tension headache, and normal MRI finding consulted our pain clinic. We performed right SGB in combination with greater occipital nerve block. The next day, we performed left SGB with 6 ml of 0.25% bupivacaine. She had no evidence of subarachnoid block or intravascular injection. 15 minutes after injection, she abruptly developed convulsion and loss of consciousness. She was given artificial respiration with oxygen. The diagnosis of ruptured left posterior communicating aneurysm was confirmed by 4-vessels angiography.

Single subcutaneous administration to S.D rats of both sexes was performed to investigate the acute toxicity of Syndella gel, a new topical drug containing deproteinised dialysate of calf's blood and micronomicin sulfate. $LD_{50}$ values for S. D rats were 23,047 mg/kg for male and 23,725 mg/kg for female. The death occurred within 24 hours after administration at doses over 19,200 mg/kg. The main cause of death seemed to be respiratory disturbance by acute shock. Major general symptoms induced by injection subcutaneously with Syndella gel were underactivity, decreased respiratory rate, salivation, tremor and loss of consciousness. No significant body weight changes and gross findings of internal organs in treatment groups in comparison with those of control groups was observed at any dose levels in Syndella gel.
