BACKGROUND AND PURPOSE: Valproic acid (2-propylpentanoic acid) which enhances GABA synthesis and blocks it's degradation has been useful treatment of migraine and may activate GABA receptors to modulate trigeminal nociceptive neurons innervating the meninges. But the mechanism and action of sodium valproate in headache is not clear. To investigate the mechanism of valproic acid action in headache model, we compared the change of dural plasma protein extravasation in both substance-P neurogenic inflammation rats with valproic acid pretreatment and without valproic acid pretreatment. METHOD: Sprague-Dawely rats were pretreated with valproate 30 minutes prior to substance-P administration in order to test the effects of sodium valproate on dural plasma protein extravasation by detecting the amount of extravasated Evans blue in the dura matter. To examine the abilities of either bicuculine (GABAA antagonist) and phaclofen (GABAB antagonist) to reverse the effect of valproate, they were administered 5 min before valproate administration. After then we also test the effect of muscimol (GABAA agonist) and bicuculine (GABAA antagonist) in substance-P induced neurogenic inflammation rats. RESULTS: Intraperitoneal injection of sodium valproate and muscimol reduced dural plasma protein extravasation after intravenous substance-P administration. The GABAA antagonist bicuculine completely reversed the effect of valproate and muscimol on plasma extravasation following substance-P administration, whereas the GABAB receptor antagonist, phaclofen, did not. CONCLUSION: We concluded that the attenuation of dural plasma protein extravasation by valproate and muscimol is mediated by via GABAA receptors within the meninges. Agonists and modulators at the GABAA receptor may become useful for the development of selective therapeutic agents for migraine headache.

During the period from July 1975 to June 1982 we performed 17 Putti-Platt operations on 16 males and one female, ranging from 19 to 39 years. The average follow-up period was 3.8 years in 13 cases of them. The results were as follows: 1. The ages in initial dislocation were ranged from 14 to 31 with an average of 18.5 years. 2. Right side was involved in 15 cases and. left in 2 cases. 3. On radiological finding Hill-Sachs lesion was found in 41%.0n pathological finding at operation of 15 cases, Bankart lesion was seen in 73%, Hill-Sachs lesion in 60%, glenoid erosion in 33%, capsular loosening in 33%, and capsular tear in 13%. 4. Limitation of external rotation compared with sound opposite side was measured in 12 to 40 with an average of 19.2 degrees. 5. The Putti-Platt operation is considered as sound, surgical procedure that gives excellent functional results.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.

A sphenoid mucocele often presents late due to its deep seated anatomical site. And it has varied presentation due to its loose relationship to the cavernous sinus and the base of the skull. We describe a case of large sphenoid sinus mucocele. A middle aged old man suddenly developed third cranial nerve palsy. Brain imaging study revealed an isolated sphenoid sinus mucocele, compressing right cavernous sinus. Endoscopic marsupialization of the mucocele via transnasal approach led to complete resolution of the third cranial nerve palsy. Involvement of the third cranial nerve in isolated mucocele is rare but important neurosurgical implications which must be excluded. In addition, proper and timely treatment must be performed to avoid permanent neurologic deficit.

Pediatric urolithiasis is a rare disease. Although the causes of pediatric urolithiasis are unknown, the metabolic conditions account for more than 50% of diagnoses. Because pain originating from stones may mimic a colic in infants, it is difficult to diagnose a stone in pediatrics. To our knowledge there is no case of urolithiasis reported in Korean infants. Here we report a case of a calcium-uric acid urolithiasis in an infant.

Although it is known that hypothyroidism can cause cardiac dysfunction, it is very hard to find a case report on sudden death due to hypothyroidism. There are only two reported cases on medline; one is about a 15-year-old girl who died suddenly of Hashimoto's thyroiditis and the other is about a 31-year-old man who also died suddenly of hypothyroidism associated with chronic lymphocytic thyroiditis. Recently we found a young woman who unexpectedly died while she was sleeping. She was diagnosed as hypothyroidism when she went to hospital about a month before she died. At autopsy there were roughly four abnormal findings; Hashimoto's thyroiditis, mild chronic active hepatitis, diverticulosis and accessory spleen. Trace of chlorpheniramine was detected in gastric remains and blood alcohol level was 0.37 percent. To our knowledge, this is the first case reporting sudden and unexpected natural death associated with hypothyroidism in Korea.
