Enflurane is a fluorinated volatile anesthetic, mostly eliminated unchanged in exhaled air. A few cases of hepatitis are reported to be associated with its administration.
Enflurane has been shown to increase slightly the percentage of abnormal spermatozoa in mice. It has more depressant effects on AV nodal recovery properties than halothane or isoflurane.
Enflurane can produce seizure activity in the cortical EEG, in vivo, at concentrations associated with surgical anaesthesia. The plasma bromide concentration increased significantly when halothane was used.

The predictability of the inspiratory and endexpiratory concentrations of the volatile anaesthetics isoflurane and enflurane by pharmacokinetic models was investigated. We investigated ketamine pharmacokinetics in eight dogs anesthetized with en flurane. We correlated ketamine concentration in plasma (KET) with its ability to reduce the en Flurane concentration required for anesthesia.

| Graves Disease A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy). | 0 | 1.96 | 1 | 0 |

| Status Epilepticus A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.

| Hypospadias A birth defect due to malformation of the URETHRA in which the urethral opening is below its normal location. In the male, the malformed urethra generally opens on the ventral surface of the PENIS or on the PERINEUM. In the female, the malformed urethral opening is in the VAGINA. | 0 | 1.96 | 1 | 0 |
| Dermatomyositis, Adult Type [description not available] | 0 | 1.96 | 1 | 0 |
| Dermatomyositis A subacute or chronic inflammatory disease of muscle and skin, marked by proximal muscle weakness and a characteristic skin rash. The illness occurs with approximately equal frequency in children and adults. The skin lesions usually take the form of a purplish rash (or less often an exfoliative dermatitis) involving the nose, cheeks, forehead, upper trunk, and arms. The disease is associated with a complement mediated intramuscular microangiopathy, leading to loss of capillaries, muscle ischemia, muscle-fiber necrosis, and perifascicular atrophy. The childhood form of this disease tends to evolve into a systemic vasculitis. Dermatomyositis may occur in association with malignant neoplasms.

| Polyneuropathies Diseases of multiple peripheral nerves simultaneously. Polyneuropathies usually are characterized by symmetrical, bilateral distal motor and sensory impairment with a graded increase in severity distally. The pathological processes affecting peripheral nerves include degeneration of the axon, myelin or both. The various forms of polyneuropathy are categorized by the type of nerve affected (e.g., sensory, motor, or autonomic), by the distribution of nerve injury (e.g., distal vs. proximal), by nerve component primarily affected (e.g., demyelinating vs. axonal), by etiology, or by pattern of inheritance. | 0 | 1.96 | 1 | 0 |

| Mitral Valve Stenosis Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause. | 0 | 1.95 | 1 | 0 |
