Single dose(1.0 cc) of 20 % 2, 6-diiodo-4-nitrophenol solution was injected to 82 hookworm infected cases and 79% of them became egg-negative within 2-3 weeks after the injection. Mild to severe local pain were experienced for several minutes in all cases. Two cases complained of paralysis of the arms of the same side. The tablet of the same formula was given orally to 21 cases for 1-4 days. The 2-4 day course with 360 mg/day were enough to eliminate the parasite, and showed no systemic side effects.

Takayasu's arteritis is briefly as an inflammatory process of unknown etiology occuring dominantly in young female most commonly involving the great vessels arising from the aortic arch. The disease process results in stenosis and obliteration of involved vessels. Syncope in Takayasu's arteritis is known to result from decreased blood flow to brain because of stenosing blood vessels. We herein describe a case of paroxysmal atrioventricular block in a 40-year old man with Takayasu's arteritis. The patient presented with spontaneous recurrent syncope associated with paroxysmal AV block. Carotid sinus pressure repeatedly induced paroxysmal AV block and syncope. Carotid sinus pressure after pretreatment of atropine failed to induce AV block or syncope. Coronary angiogram was normal. We concluded that syncope in this patients was attributed to carotid hypersensitivity rather than decreased blood flow to the brain due to vessel stenosis.

OBJECTIVE: To evaluate the changes of maximum fibrillation potential amplitude and root- mean-square (RMS) value of denervation potential after nerve injury using power spectrum analysis. METHODS: The sciatic nerve was transected in 8 rats, and was compressed in 6 rats. Denervation potentials were collected in gastrocnemius using monopolar needle weekly after nerve injury. The change of RMS value of 1 second epoch of denervation potentials with time was evaluated and compared with the change of maximun fibrillation potential amplitude. RESULTS: In nerve-transected rat, the RMS value declined linearly with time after injury. On the contrary, the amplitude of fibrillation potentials declined much rapidly during first 3 weeks. In nerve-compressed rat, both the RMS value and amplitude of fibrillation potential increased for 2 weeks after injury, and declined thereafter. As the result of simple regression analysis, the changes of RMS value correlated better than changes of fibrillation amplitude in all 8 nerve-transected rat. CONCLUSION: The RMS value of denervation potentials correlated well with time after nerve injury in animal experiments. Measurement of the RMS value might be helpful to evaluate the time after peripheral nerve injury, but long-term human data should be essential for clinical application.

This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malunioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort 1 osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

We obtained successful functional and esthetic results by grafting of iliac marrow-cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony support to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantral fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with pre-orthodontic treatment. The other case. Bone grafting was done after removal of prosthesis with no pre-orthodontic treatment. 2. After mucoperiosteal incision in cleft area, the mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiograph and prosthetic treatment of missing teeth were done.

Pre-surgical and post-surgical change in adult clef lip and palate patient following Le Fort I advancement osteotomy combined with bone graft was evaluated clinically and cephalometically. We obtained a successful function and esthetic improvement. The bone graft of alveolo-palatal clefts provides a stable bone support to the adjacent teeth of the cleft area, and well union of adjacent bone tissue, the closure of oronasal fistula and improvement of speech problem. Le Fort I osteotomy following the ostectomy of nasal septum for advancement of the maxilla was obtained relative improvement of esthetics and functional occlusion. 1. The orthodontic correction was required before and after surgery. 2. In this case, there was a limited range of anterior advancement of the Premaxillary-segment due to the scar tissue. 3. After 8 months of operation, we could show the new bone deposition on the cleft sites in dental radiograph and then the prosthetic treatment to the missing teeth was done.

Penetrating ocular injuries with intraretinal foreign body(IRFB) are increasing and may result in significant visual morbidity. We evaluated retrospectively 22 eyes of 22 patients who had undergone pars plana vitrectomy for removal of IRFB at Dong-a University Hospital from July 1990 to June 1996. The majority of patients were adult male(95.5%). The nature of all IRFB was magnetic property and the causes of injury were hammering and cutting work(77.3%). Preoperatively, eyes were complicated with vitreous hemorrhage and opacity(59.1%), traumatic cataract(45.%), retinal detachment(36.4%), and corneal opacity(22.7%). Postoperative complications included vitreous hemorrhage and opacity(36.4%), retinal detachment(22.7%), and proliferative vitreoretinopathy(18.2%). In our study, poor visual prognosis was obtained in cases of corneal entrance site, IRFB larger than 2mm in size, IRFB located posterior to equator and IRFB associated with retinal detachment.

PURPOSE: We investigated the impact of treatment on electroencephalogram (EEG) findings, and determined treatment efficacy according to EEG findings and antiepileptic drugs in children and adolescents with recurrent headaches. METHODS: We retrospectively analyzed the medical records of 131 patients, aged 5–18 years, with recurrent primary headaches and performed EEG study who visited the Chosun University Hospital Department of Pediatrics from January 2014 to December 2016. Headaches were classified according to the International Classification of Headache Disorders-III (ICHD-III, beta version), and EEGs were analyzed for changes after treatment for primary headache. RESULTS: Among 131 patients, we successfully collected completed all the data on 30 patients (18 boys, 12 girls). The frequency of abnormal EEG findings before treatment was not significantly different according to the type of primary headache (P= 0.390). The mean frequency (P=0.001), duration (P=0.002), and intensity of headaches (P < 0.001), and disability due to headache (P=0.003) were significantly decreased after treatment in patients with epileptiform discharges on EEG. The mean frequency and intensity of headaches and disability due to headache (P < 0.005) was also significantly decreased in the patients with both slow and normal EEG findings. The mean frequency (P=0.007), duration (P=0.01), and intensity (P < 0.001) of headaches, and disability due to headache (P=0.002) were significantly decreased after treatment with antiepileptic drugs in patients with epileptiform discharges. CONCLUSION: Abnormal EEG findings were no significant differences in terms of type of primary headaches. Our results suggest that antiepileptic drugs may alleviate headaches in patients with epileptiform discharges on EEG.
