Serial Changes of Heat Shock Protein 70 and Interleukin-8 in Burn Blister Fluid

BACKGROUND: It has been reported that heat shock protein 70 (HSP70) and interleukin-8 (IL-8) play an important role in cells during the wound healing process. However, there has been no report on the effect of HSP70 and IL-8 on the blisters of burn patients. OBJECTIVE: This study aimed to evaluate the serial quantitative changes of HSP70 and IL-8 in burn blisters. METHODS: Twenty-five burn patients were included, for a total of 36 cases: twenty cases on the first day, six cases on the second, five cases on the third, three cases on the fourth, and two cases on the fifth. A correlation analysis was performed to determine the relationship between the concentration of HSP70 and IL-8 and the length of the treatment period. RESULTS: The HSP70 concentration was the highest on the first day, after which it decreased down to near zero. Most HSP70 was generated during the first 12 hours after the burn accident. There was no correlation between the concentration of HSP70 on the first day and the length of the treatment period. No measurable concentration of IL-8 was detected before 5 hours, but the concentration started to increase after 11 hours. The peak value was measured on the fourth day. CONCLUSION: While HSP70 increased in the first few hours and decreased afterwards, IL-8 was produced after 11 hours and increased afterward in burn blister fluid. These findings provide new evidence on serial changes of inflammatory mediators in burn blister fluid.

A Case of a Male Presenting with Periocular Pain and Diplopia at an Emergency Department: Tolosa-Hunt Syndrome

Tolosa-Hunt syndrome is a rare self-limiting disease characterized by a painful, unilateral ophthalmoplegia caused by an idiopathic granulomatous inflammation in cavernous sinus, the superior orbital fissure or the orbital apex. We report a case of a 51-year-old man who presented at the emergency department with periocular pain and diplopia. Physical examination, and radiological and laboratory testing performed at that time were diagnostically inconclusive. After hospitalization, the patient was diagnosed with Tolosa-Hunt syndrome. Treatment with high dose steroid was started; by 2 days later, the periocular pain was relieved and other symptoms had improved. The rarity of Tolosa-Hunt syndrome calls for knowledge of the disease and attention by an emergency physician. The case report includes as summary of the syndrome, its' diagnosis and treatment.
