The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

A 28-yr-old woman, weighing 61 kg with bleeding myoma of uterus was scheduled for total abdominal hysterectomy. There was no history of cardiac arrhythmia or syncope. She was not premedicated. The heart rate was 115 beats/min and arterial pressure was 155/95 mmHg, immediately before the induction of anesthesia. Under the preoxygenation, anesthesia was induced with IV injection of thiopental sodium 250 mg followed by succinylcholine 75 mg. About 20 seconds after the succinylcholine bolus, the ECG showed an abrupt change from sinus rhythm to asystole without any stimulus including laryngoscopy. After a precordial thump and atropine 0.5 mg IV, tracheal intubation and ventilation with 100% O2 were quickly accomplished. Normal sinus rhythm with heart rate of 87 beats/min returned during laryngoscopy and intubation. The interval from the sinus arrest to the reestablishment of normal sinus rhythm was only 15 seconds. Surgery proceeded uneventfully and the patient recovered without any complication.

BACKGROUND: Blunted perception of dyspnea, which may be related to the increased mortality, has been demonstrated in patients with a history of near-fatal asthma and in the elderly. OBJECTIVE: The purpose of this study was to evaluate the relationship between the perception of dyspnea and the severity of asthma. METHOD: Baseline spirometry and Borg score change(A Borg score) during breathing through an inspiratory muscle trainer were measured in 27 consecutive asthma patients and 11 normal subjects. RESULTS: The baseline Borg score was negatively related to FEV1 A Borg score was significantly lower in asthmatics than in controls at high level of loads. A Borg score was lower in severe asthma than in mild asthma. A Borg score was positively related to the baseline FEV1. Seventy-five percent of severe asthma, 62.5% of moderate one, and 9.1% of mild one showed impaired dyspnea perception. Dyspnea perception was related to age(r, = -0.49, p<0.001). CONCLUSION: Three quarters of patients with severe asthma showed impaired dyspnea perception to inspiratory resistive load. Dyspnea perception was related to asthma severity and age.

Crypt glandular infection theory is accepted as an explanation of anal fistula's major cause. However, the pathogenesis of an anal fistula in Crohn's disease is different from that of a conventional anal fistula because a Crohn's anal fistula is caused by ulceration which, in turn, is caused by transmural inflammation of the rectal wall due to Crohn's disease. The difficulty with operating on anal fistulas in Crohn's disease lies in the fact that healing of the wound is inhibited because of continuous inflammation of the anorectal tissue due to Crohn's disease. Hence, there is a high possibility of incontinence due to sphincter muscle injury. Especially, because almost all Crohn's disease patients have frequent defecation and diarrhea, the patients will suffer more if incontinence occurs. Nowadays, even with increased understanding of the etiology of Crohn's disease, new medications, and aggressive surgical approaches, the result of treatment is still not satisfactory. Recently, since Korean eating habits have changed to include more western-style food in the diet, inflammatory bowel disease, such as Crohn's disease, is expected to increase. Consequently, the number of cases of anal fistulas in Crohn's disease is also expected to increase. The authors reviewed 20 confirmed cases of anal fistulas in Crohn's disease, which were treated from January 1993 to December 1995 at Song-Do Colorectal Hospital. The results are as follows: 1) Anal fistulas in Crohn's disease were present in 20(0.6%) of the 3378 cases of anal fistulas treated during the time period considered. 2) The male to female ratio for these 20 cases was 2: 1, and the most Prevalent age group was the 3rd decade, followed by the 2nd decade, the 4th decade, and the 5th decade in that order. 3) Three cases of anal fistulas whose origins could be explained by crypt glandular infection theory and which did not involve the rectum healed, although the healing was delayed. 4) Seventeen cases of anal fistulas whose origins could not be explained by crypt glandular infection theory and which involved the rectum did not heal after the operation. he results of the study show that anal fistulas whose origins can be explanined by crypt glandular infection theory and which do not involve the rectum can be cured by conventional fistula surgery. However, perirectal fistulas whose origins can not be explained by crypt glandular infection theory and which involve the rectum do not heal. Because there is the possibility of incontinence after a conventional operation, it is suggested that, in the cases of perirectal fistulas in Crohn's disease, better results, although not completely satisfactory, can be obtained by long-term seton drainage and diversion colostomy.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.

Pneumoconisosis was the first reported occupational disease in korea and was the most common occupational disease until 1990. Nowadays pneumoconiosis is the second most common occupational disease which accounts for more than at least 40% of all the occupational diseases in Korea. Many studies have been carried out in the prevalence rate, incidence rate, and risk factors assessment of pneumoconiosis. Workers exposed to dust used to take health examination once annually by the Industrial Safety and Health Act(1981). The number of coal workers has steadily decreased due to coal rationalization projects which have been strongly driven by the government since 1988 and the occupational environment has been improving. So, the incidence rate of pneumoconiosis will probably be lower in the future. But a disease control system administed for patient control and compensation, which is not involved in epidemiologic studies may not figure out the prevalence rate, incidence rate, mortality rate and the extent of severity of pneumoconiosis. Several problems and expected solutions are mentioned here as follows: 1. workers exposed to dust and pneumoconiosis patients are under government control, but the retired workers are not. Since we evaluate only visiting retired workers, we don't know exactly the current status and whole scale of the retired workers. If possible, the construction of cohort in all the retired workers is needed. 2. Since most of pneumoconiosis patients retired from the work and had changed their job, it is difficult to figure out the prevalence rate of pneumoconiosis just depending on the annual health exam for those workers at risk. So, systemic control for all pneumoconiosis patients is needed. 3. It is difficult to diagnose the onset of pneumoconiosis. We make a decision the time when the patient is diagnosed with pneumoconiosis on its onset. It is difficult to estimate it, especially in the case of retired workers because we can evaluate only persons with respiratory symptoms. The solution of such a problem is construction of cohort in all of the retired workers. 4. Because the patients who died outside of hospital don't seem to be reported, the mortality rate of pneumoconiosis is underestimated. So, systemic control and follow-up observation for all pneumoconiosis patients is needed. 5. A definite severity classification criteria for pneumoconiosis hasn't been established in Korea. We should try to make one. 6. Since workers who had exposed to dust in various mines at least 1 yr are subject to pneumoconiosis laws, workers easily don't report their full dust exposure history. Therefore we can't obtain the exact lifetime dust exposure from administrative data. We should try to make basic raw data of whole dust exposure in workers. It's concluded that the construction of cohort in workers who are or were exposed to dust in various mines is required and epidemiologic study of pneumoconiosis should be carried out with the administrative control of pneumoconiosis side by side. With the database of these materials, we can speculate and devise the measure for the further affecting subjects who are presumed to be most common in manufacturing industries.
