Duration of remission phase of 36 Korean patients with glossopharyngeal neuralgia / 대한마취과학회지

BACKGROUND: Glossopharyngeal neuralgia has the characteristic of a long remission phase between the pain attack phases. Although the concept of remission is very important for the treatment of patients with glossopharyngeal neuralgia, due to the rarity of the disease, clear statistical studies on the remission phase for glossopharyngeal neuralgia are almost non-existent. METHODS: Previous chart reviews and phone interviews were conducted on a total of 38 patients. Among these study subjects, two patients were excluded because of their known secondary glossopharyngeal neuralgia from their brain tumors. Hence, the average duration of remission was investigated on 36 patients with idiopathic glossopharyngeal neuralgia. RESULTS: For the 27 patients who experienced their first remission, the average duration of the remission was 3.1 years. Among them, the average duration of the second remission of the 17 patients was 2.5 years, and for 4 patients who experienced a third remission, the average duration of the remission phase was 1.9 years. CONCLUSIONS: The difference in the mean duration of the remission phase of the 1st, 2nd, and 3rd are not statistically significant, and the occurrence rate of the left or right side and of the gender, male or female, are also statistically insignificant. However, it is possible to infer that a patient might face a pain attack phase when his or her remission phase has lapsed for about three years. This prediction may be applied when developing treatment plans for patients with glossopharyngeal neuralgia.

Respiratory insufficiency in a patient with preeclamsia and hypothyroidism developed after general anesthesia for emergency cesarean section: A case report / 대한마취과학회지

Anesthesia and surgery in a patients with undiagnosed or untreated hypothyroidism can carries the risk of potential complications such as prolonged unconsciousness, respiratory insufficiency, hypotension, hyponatremia, congestive heart failure, and even coma. A 33-year-old gravida was admitted at 36 weeks gestation with hypertension, proteinuria, generalized edema, and intrauterine fetal growth retardation. She had thyroidectomy for thyroid mass six years ago. Because of doubt of uterine abruption, emergency cesarean section was performed without result of thyroid function test. Preeclamsia and mild hypothyroidism show similar symptoms and it can make difficult to diagnose hypothyroidism. We experienced delayed recovery and respiratory insufficiency in a patient with preeclamsia and undetected hypothyroidism during emergence from general anesthesia. She was fully recovered after ventilatory care in intensive care unit.

Ketamine Infusion Therapy in a Patient of Posttraumatic Syringomyelia / 대한통증학회지

The clinical syndrome of posttraumatic syringomyelia can complicate major spinal trauma and develops many months after spinal injury. The 50-90% of patients experienced the pain and especially the component of central pain. In patients with central pain following spinal cord injury, ketamine has been shown to be an effective analgesic. We report a case of posttraumatic syringomyelia in a 30-year-old woman who complained of central pain, weakness of both legs and dysesthesia. She had not responded to pulsed radiofrequency, or lidocaine infusion therapy, but a continuous intravenous infusion of ketamine, an N-methyl-D-asparate receptor antagonist, reduced her severe central pain. In conclusion, a ketamine infusion therapy resulted in a significant reduction of central pain without decreasing of motor power and function.
