Distinguishing epileptic seizure from non-epileptic seizure is a common diagnostic problem. Neurogenic or cardiac syncope can appear similar to atonic and even convulsive seizures. Classic migraine and transient ischemic attacks may also resemble epileptic seizures. Sleep disorders including REM sleep behavior disorder, nocturnal paroxysmal dystonia, and narcolepsy likewise simulate an epileptic seizure. Movement disorders such as paroxysmal dyskinesia can be misinterpreted as epileptic seizures (reflex epilepsy or myoclonic seizures). Psychogenic seizures are often misdiagnosed as an intractable epilepsy. Prior to the definitive diagnosis of epilepsy, possible non-epileptic seizures should be excluded. For the correct decision, a thorough and systematic history taking is important. In addition, EEG, pseudoseizure induction test, head-up tilt test, EKG, sleep studies, and video-EEG monitoring may be necessary. Misdiagnosis of non-epileptic seizures as epilepsy may result in unnecessary anti-epileptic drug use. At the same time, we should let the patients understand what the epilepsy is and that epilepsy is a treatable disease.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

Sixteen microvasular free flap transfers have performed during recent two years in this department, which was first attempt in Korea. Neurovascular free flap was nine and vascular free flap was seven. The donor flaps were thirteen dorsalis pedls falps, two groin flaps and one latissimus dorsi flap respectively. The recipient sites were heel pad loss, vital organ exposure and scar contracture lesions in extremity. Their main cause of soft tissue defect was traumatic in all. All patients have experienced more than two times of split thickness skin graft before free flap transfer. The success rate of vascular free flap transfer was 94%. The only one failure case was due to venous thrombosis, but secondary split thickness skin graft performed with satisfactory result. The follow up period was from 5 months to 20 months. Sweating in transferred free flap was found at all neurovascular free flap within postoperative 4 months. Adequate 2-point discrimination was obtained at six patients of nine neurovascular free flaps and protective sensation seems to progressively improve in remained three patients. Two point discrimination was shortened at hand after neurovascular dorsalis pedis flap transfer in two cases. The weight bearing function at heel pad region and tactile sensation at hand have satisfactorily recovered after free flap transfer. Free flap transfer have many advantages compare to conventional skin graft, such as shorter therapeutic time, lesser physical and economic burdens, primary covering to vital organs and protective sensation of neurovascular free flap transfer. The most important factors are meticulous microvascular operation technique and anatomic knowledge.

The tuberculous infection of the skeletal system especially, tuberculous spondylitis is frequently encountered with orthopedic fields. Up to date, Various methods of the treatment are present but each method has problems. Recently, as a development of the microsurgical instrumentation and surgical technique, we had been tried to the two patients of tuberculous spondylitis by vascularized fibular bone graft and anterior fusion. The advantages were as follows; 1. Shortened the bony union times by this operative method. 2. Earlier returning to the social activities compared to the ordinary method. 3. The children involved tuberculous spondylitis with severe kyphosis, who can be corrected the severe kyphosis by this operative method. 4. We can be obtained the rigid graft bone fixation with adequate length of bone by this operative method.

The vascular graft used for the reconstruction of certain types of vascular occlusive diseases and traumatic damages of the vessel, is very important, especially for the reconstruction of microvascular damages as occuring in hand injuries. Until recently microvascular graft done by microsurgical techniques was rare compared to the many- numbered large vessel grafts. But their biologic fate is currently uncertain. We studied the histologic changes occuring in the microvesseles of 1.5cm in length and 2mm in diameter, which were grafted to the femoral artery of rabbits by recently developed microsurgical techniques. Histologic changes were observed between different donor materials with different time intervals. For 60 rabbits which were used as experimental material, 15 cases received autogenous venous graft (group I). 15 cases autogenous arterial graft (group II) and 15 cases homogenous arterial graft (group I). The observd post-operative dates were 3,7,14.60 and 90 days for each respective group. The results were summerized as follows: 1. The patency rate of grafted vessels using microsurgical technique was 91.2%. 2. The histological changes observed were: a. On the 3rd and 7th day post-operatively, mainly inflammation, formation of thrombus, increased population of endothelium and formation of suture granuloma around the suture site were observed. b. On the 14th day, decreased numbers of inflammatory cells, progressed organization of thrombus, disorganization of the medial muscle layer of the grafted vessels and degeneration of endothelium were observed. c. On the 60th day, inflammatory cells and previously formed thrombi were no longer found and increased amount of fibrosis was prominent instead. 3. The autogenous venous graft group showed less histological changes in every aspect compared to the other two groups. 4. The autogenous arterial graft group showed considerable histological changes, but endothelial lining cells were well preserved. 5. In the homogenous arterial graft group, good patency rate of grafted vessel were observed despite of severe inflammatory change initially. 6. It can be concluded from the above observation that the micrcvascular graft thought to be most useful in recstablishing circulation of injured vessels was the autcgenous venous graft. Homogenous vessel graft and autogenous graft artery were also found to be applicable when autogenous vencous graft is not available.

It is notoriously difficult to obtain a sound bony union of large segmental bone defects secondary to trauma or following tumor resection, infected nonunion, congenital pseudarthrosis of the tibia, and avascular necrosis of the femoral head with conventional methods. Recent advances in microsurgery have made it possible to provide a continuing circulation of blood in bone grafts so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. Thus, the grafted bone is achieved more rapid stabilization of bone fragments separated by a large defect without sacrificing viability. Thirty nine cases of the free vascularized fibular graft had been performed in the Department of Orthopedic Surgery, Kyung Hee University Hospital during the period of 3 years from October 1978 to December 1981. Of these, ll cases were congenital pseudarthrosis of the tibia, 4 cases were tuberculous spondylitis, 4 cases were infected nonunion, 7 cases were large segmental bone defects secondary to trauma, 9 cases were avascular necrosis of the femoral head and the other was one case. The results were obtained as follows: 1. The advantages of free vascularized living fibular graft are one stage procedure, resistance of torsion and angular stress, union with rapid hypertrophy of the graft, a shorter immobilization period and more rapid incorporation of the graft into the recipient area. 2. Free vascularized fibular graft can be widely used in the field of Orthopedic surgery. 3. The fibula is the bone best suited for reconstruction of a defect in a long bone. 4. In children, distal tibiofibular synostosis must be performed. 5. For prevention of clawing toe, the muscles around the bone is meticulously dissected, 6. Evaluation by selective arteriography and isotopic scanning both before and after operation may be used to assess the viability of the fibula graft.

Of the shoulder injuries in trauma, none are more common than those involving the acromioclavicular joint. There are many procedures described for treatment of injuries of the acromioclavicular separation but difficulties continues to be encounted. To know the functional anatomy of this joint and mechanism of injuries makes more proper treatment. We operated the 16 cases of acromioclavicular separation in the Dept of Orthopedic Surgery, Kyung Hee College of Medicine from January 1975 to August 1978. The following results were obtained. 1. This injuries is more prevalent in male with peak incidence in the third and fourth decades. 2. The mechanism of injuries were traffic accident, falling down and the other direct injuries with in orders. 3. The difference of distance between coracoid process and clavicle gives the information of Type II and Type III. 4. The operative procedures in Type II and Type III are good treatment of acromioclavicular separation.
