Transient hyperkalemia is well known to occur in man following intravenous administration of succinylcholine chloride. We studied the change of the serum potassium concentration after injection of succinylcholine in nonburn patients and electricburn patients, physical status 1 or 2 adopted by the American Society of Anesthesiologists. We compared two groups: Non-burn patient group(Group 1) as control, Electric burn patient group (Group 2) as experimental. The following results were obtained: 1) In non-burn patient group(Group 1) serum potassium concentration was slightly decreased in the 1st, 2nd, 3rd, 4th, 5th, 6th and 10th minute after succinylcholine injection compared with control, but nostatistical significance was noticed in this group. 2) In electric burn patient group (Group 2) serum potassium concentration was maximally increased compared with the controls. Statistical significance was noticed at the 2nd and 3rd minute after succinylcholine injection in this group.

The cataract extraction in vitrectomized proliferative diabetic retinopathy(PDR) may be different from the ordinary non-vitrectomized patients in several points. We tried to know what`s the problems during the operation, how`s the visual outcomes and the postoperative complications in these eyes. In 18 previously vitrectomized PDR patients(25 eyes), we performed the extracapsular cataract extraction(ECCE) in 7 eyes and the phacoemulsification in 18 eyes. The intraoperative problems were insufficient dilation of pupil, unstability of (anterior and posterior) chamber depth, and difficulty in removal of cortex, which is firmly adherent to the posterior lens capsule. Opacity of posterior lens capsule, elevation of intraocular pressure, exudative pupillary membrane, posterior synechia and corneal edema were the major postoperative complications. In 22 eyes(88%), the visual acuity was increased more than 2 lines, Cataract extraction was easier and less postoperative complications these cases.

The cataract extraction in traumatic cataract with corneal laceration is likely to be different from the ordinary cataract extraction in several points. We tried to know the problems of the operation, the visual outcomes and the postoperative complications in these eyes. In 25 traumatic cataract with corneal laceration, we performed cataract extraction and corneal suture at the same time in 11 eyes and at different time in 14 eyes. The intraoperative problems were difficult anterior capsulotomy, corneal opacity, difficult lens delivery etc.The major postoperative complications were anterior chamber inflammation, corneal edema, posterior capsular opacity and exudative pupillary membrane. In 23 eyes[92%], the visual acuity was increased more than 2 lines. Cataract extraction in traumatic cataract with corneal laceration was very effective surgery, and cataract extraction after primary corneal suture has done had good results in severe corneal laceration with suspicious posterior capsular rupture and non-fitted preoperative preparation.

Hirayama disease usually selectively involves lower cervical myotomes (C8, T1). Thus, patients usually manifest with atrophy and weakness of small hand muscle. Predominant isolated involvement of proximal arm is rarely reported in Hirayama disease. Here, we report a case of Hirayama disease who had focal weakness and wasting, mainly confined to right biceps brachii muscle, with prominent shifting of dural sac in C4-5 segment by dynamic flexion magnetic resonance imaging (dfMRI), which may explain this unusual distribution of the disease.

Nerve compression syndromes can be caused by compression of the peripheral nerve from interior or exterior of the nerve. In the upper extremities, brachial plexus, ulnar nerve and median nerve can be compressed in thoracic outlet syndrome, cubital tunnel syndrome and carpal tunnel syndrome respectively. Because these syndromes are caused by compression, decompressive management can be expected to be the principle of treatment. From Jan. 1980 to Dec. 1988, 94 patients were admitted and treated for nerve compression syndromes of the upper extremities in Seoul National University Hospital. Among these, 52 patients suffered from carpal tunnel syndrome and operation was performed to 86 hands. Twelve patients suffered from thoracic outlet syndrome and 25 from cubital tunnel syndrome. Ten patients were treated with conservative method and 84 with decompressive surgery. Satisfactory results were obtained in 92.3% of carpal tunnel syndrome and 84% of cubital tunnel syndrome. Of 4 operated cases of thoracic outlet syndrome, 3 cases were satisfactory.

After the clinical introduction of halothane, the problem of hepatotoxicity and mechanism has major implications for the practice of anesthesiology. This study was undertaken to investigate the liver function change after halothane anesthesia in 22 cases of electric burn patient. In this study, all cases had a great elevation of SGOT and SGPT levels, and previous experience of inhalation anesthesia, jaundice and who had not been transfused during this study. The following results were obtained: 1) Elevation of the SGOT and SGPT in electric burn patients may be influenced by damage of skeletal muscle and transaminase released into systemic circulation. 2) In the electric burn patients, elevation of the SGOT and SGPT does not enhance the susceptibility of the liver to injury by halothane.

In 1971 inclusion body myositis was reported by Yunis and Samaha. This disease is similar with chronic multiple myositis clinically. Pathologically, inclusion body myositis is characterized by intracytoplasmic vacuole with degenerating fibers and accompanied with inclusion body in internal nucleus and cytoplasm. Since then 240 cases of inclusion body myositis have been reported in the world including 3 cases in Korea. A 27 years-old lady had inclusion body myositis, which show slowly progressive muscular weakness. We confirmed this with clinical symptom, muscle biopsy, and electrophysiologic study. We report the typical manifestation of inclusion body myositis in a 27 years-old lady with the brief review of literature.

Cubitus varus deformity following elbow fracture in children rarely limits the function of the upper extremity, but the patients and/or their parents often request an operation for the aesthetic purpose. Various surgicsl techniques have been proposed to correct the deformity, however, the complications following operation are still common. We critically reviewed 55 patients with cubitus varus deformity treated by supracondylar closing osteotomy at Seoul National University Hospital between January, 1980 and April, 1989, and report on 25 patients who had at least one year follow-up (average 4.0 years). The results were graded as excellent (13 cases), good (8 cases), and poor (4 cases). The average amount of correction was 29.1 degrees by humero-elbow-wrist angle. There were two cases with ulnar nerve palsy and one case with radial nerve palsy, however, all of which were spontaneously recovered with time. The factors related to poor results were age at operation, degree of deformity, improper wedge size, and nerve palsy. In this article, we also illustrate our new, simple and safe technique of supracondylar closing spring (incomplete) osteotomy based on careful preoperative planning and special attention to surgical details.

Purpose: This study aimed to find a correlation between the occlusal plane and two reference planes that are frequently used in semi-adjustable articulators. Materials and Methods: Sixty-two males and fifty females with normal articulation were recruited and the lateral cephalograms of these patients were taken. The angles between the Frankfort horizontal (FH) and the occlusal planes, the angles between the gnathologic and the occlusal planes, and the angles between the FH and gnathologic planes were measured on the lateral cephalograms.Result: The mean angles between the FH and the occlusal planes was 8.29°±3.62°, with 8.88°±3.09° and 7.63°±4.10°for male and female patients, respectively. The mean angles between the gnathologic and the occlusal planes was 2.77°±3.62°, and the angle between the FH and the gnathologic planes was 5.52°±3.62°. No significant differences were found in the measured angles between the male and female patients (P>0.05). Conclusion Different guidance angles may be applied to articulators for prosthodontic restoration, depending on the reference planes that the articulators use.
