Since the independent reports of Charcot and Marie and of Tooth, in 1886, interest in this familial disease has centered largely in the genetic and diagnostic aspects, and yet references in the literature to Surgical management are rare and inexact. Our experience with Charcot-Marie-Tooth disease in 4 patients operated at Seoul National University Hospital during the last 3 years is reported. Of 6 cases of Charcot-Marie-Tooth disease which have been studied, 4 patients have undergone surgery for the correction or amelioration of the crippling foot deformity. The authors' operation has consisted of triple arthrodesis, medial release, lengthening of the Achilles tendon, tendon transfer which was available and present evidence that properly designed surgical treatment can correct, prevent, or materially reduce disability of the deformed feet. Of the 4 cases reported here, all have either been reviewed or the patients have been interviewed in the last year. On the basis of adequate follow-up observations, thesurgical procedure outlined have been shown to improve the crippled condition. In spite of progressive musele wasting, the operative treatment could prevent or ameliorate the deformity. Three cases of Charcot-Marie-Tooth disease were evaluated in a long-term follow-up after having undergone surgery to correct their foot deformity. Excellent results were achieved from three of them which were maintained at final follow-up, and one is being gollowed up.

Experiences of 26 cases of electrical bone stimulation on normal adult rabbits was documented in this paper. The cathodic electrode was introduced longitudinally into the medullary cavity of the proximal tibia and the anodic electrode was introduced transversely in the distal femur of the same side. The contralateral tibia was used as the control, of which the Teflon coated Kirschner wire was introduced longitudinally into the medullary cavity. 10uA of direct current was passed continuously through the fixed wires between the proximal tibia and distal femur. At the second, fourth and sixth week, random bone scan with 99m-Tc was performed and the animals were sacrificed. The specimen X-rays of the tibia and femur were taken and the specimens were prepared for the microscopic study. The followings are obtained from this experimental study. 1. The rate of new bone formation is 69.2% in the stimulated group and 7.7% in the control group. There were also fibrosis and cartilage formation as well as the new bone formation. The fibrosis and cartrilage formation are observed only in the electrically stimulated side and their occurances are 69.2% and 11.1% respectively. So The new bone formation and fibrosis are definitely increased in the bones of the cathodic electrical stimulation than those of the control side. 2. The intramembraneous ossification is the predominent feature of this electrically stimulated new bone formation. 3. Bone and soft tissue necrosis was the main microscopic feature in the anode side. 4. Since new bone, fibrous tissue and sometimes new cartilage were observed in this study, it seems that the cathodic electrical stimulation is not specific for the new bone formation, but induce crude tissues such as bone, cartilage, fibrous tissue or vessels. Furthermore, it can be postulated that the 10uA electrical stimulation is only one of the best electrical environment for the formation of the crude tissues, especially for bone and fibrous tissue.

This clinical study is based on review of records of 87 patients with postoperative adhesive intestinal obstruction who were managed at the Department of Surgery of Dongbu City Hospital during 5 years from September, 1992 to August, 1997. The results of study were as follows: 1) The most prevalent age group was 5th decade(44.8%) and male to female ratio was 1.7:1. 2) The previous operations were operation for appendicitis(32.2%), operations for peritonitis due to peptic ulcer perforation(24.1%), gynecologic operations(13.8%), operation for gastric malignancy(8.1%). 3) The mean value of duration between previous operations and postoperative adhsive intestinal obstruction was 36 months and the mean value of duration of symptoms was two days. 4) 42(49.2%) of 87 patients were admitted under 24 hours after onset of symptoms. 5) The chief complaints on admission were abdominal pain(98.8%), vomiting(81.6%), abdominal distension(78.2%), failure to flatus(55.2%). 6) 23 cases(45.1%) of 51 cases having one or more abnormal physical and laboratory finding(fever, abdominal tenderness, abscence of defecation or gas out, or leukocytosis) were operated, and 5 cases(13.9%) of 36 cases having no physical finding were operated (p value < 0.05). 7) Emergency operation was performed in 9 cases, elective operation was performed in 19 cases which had deteriorating clinical course despite of conservative management for 48 hours, and conservative treatement was performed in 59 cases. 8) The postoperative complications were observed in 6 cases and the most common complication was wound infection(14.3%). In conclusions, The longer symptom duration and the longer interval between previous operation and onset of symptoms, the higer probability of surgical treatment is expected. The need for surgical treatment was increased acording the number of physical and laboratory findings(fever, abdominal tenderness, abscence of defecation or gas out, or leukocytosis). For the cases which have unimproving and deteriorating clinical course despite of conservative management for 72 hours, surgical operation shoud be considered.

Epidemiologic Studies*

Mass screening of cardiomegaly by chest X-ray in 144,021 (male 55,491, female 88,530) students of primary, middle and high school (6~17 years of age) in Seoul was performed and electrocardiograms of 217 cases of cardiomegaly were studied. The results were as follows; 1) Cardiomegaly (cardiothoracic ratio over 0.5) was seen in 0.19% of each sex and it was higher in middle and high school ages (12~17 years) than primary school ages (6~11 years). 2) Incidences of abnormal electrocardiogram in cardiomegaly were 59.5% in male and 54.7% of female students. Major abnormal electrocardiograms in cardiomegaly were right ventricular hypertrophy (24.8%), left ventricular hypertrophy (11.6%), biventricular hypertrophy(4.8%), complete right bundle branch block (7.7%), incomplete right bundle branch block (8.7%), first degree A-V block (5.8%) and premature beat (4.3%). 3) Left ventficular hypertrophy was seen most frequently in high school ages (15~17 years) and decreased with decreasing age. Right ventricular hypertropy was seen most frequently in primary school ages (9~11 years) and decreased with increasing age. Biventricular hypertrophy was seen most frequently in primary school ages (6~8 years) and decreased with increasing age. 4) Complete and incomplete right vundle branch block were seen commonly in 12~17 years of age and first degree A-V block in 9~11 years of age.

The tongue is located inside the oral cavity at rest, and the structural interrelations between the tongue and the oral cavity is essentially important for normal tongue function. Macroglossia is clinically diagnosed whenever the tongue does not fit the oral cavity, thus patients complain of noisy breathing, drooling, speech and swallowing dysfunction, malocclusion, and social ridicule. Partial glossectomy for macroglossia volume has been assumed to be difficult. In this study, we attempted to measure the tongue volume with the plaster tongue model in a 7-year-old macroglossia patient. This method is reliable and simple for measuring the tongue volume in macroglossia.
