Background and Objectives : Despite of numerous treatment modalities for glottic insufficiency, it still remains unresolved problem. Recently, autologous collagen injection was introduced as a new treatment for glottic insufficiency. This study was attempted to evaluate the efficacy of this treatment modality. Materials and Methods : Ten patients diagnosed as symptomatic sulcus vocalis with glottic insufficiency and agreed with this procedure were selected. Injectable collagen was obtained from the patient's dermis. It was injected into the pathologic area of the vocal fold. After injection, 4 of 10 patients were 1311owe4 up more than 5 months, and their voice were evaluated prior to injection and at 5 months after injection, using subjective, perceptual, aerodynamic, acoustic and videostroboscopic assessments. Results : In the aerodynamic assessment, 2 of 4(50%) patients was improved in MFR(mean flow rate), but no change was noted in MPT(maximum phonation time). In the acoustic assessment, no definite improvement was noted. In the subjective and perceptual assessments, 2 of 4(50%) patients was improved. In the videostroboscopic assessment, chink was reduced but still remained. Serious complication was not noted. Conclusion : Autologous collagen injection was reported as ideal treatment for glottic insufficiency, but our results were relatively unsatisfactory. But considering that our study is preliminary, it is too hasty to determine the efficacy of autologous collagen injection. We think that further study is required.

Esophageal cancer is relatively uncommon except in isolated endemic areas, but it generally devastating to the patient. Usually, by the time the disease becomes clinically evident, it is incurable. The aim of treatment is then relegated to attempting to palliate the symptoms in the best possible manner with the least morbidity and mortality. Squamous cell carcinoma in by far the commonest type of malignancy involving the body of the esophagus, accounting for more than 95 percent of all esophageal malignancies. Because the tumor’s microscopic spread is much greater than its macroscopic extent, it is necessary to resect a sufficiently long segment of the esophagus. And second tumors may occur either in the esophagus as a manifestation of a field change or in other organs. Recently we had experienced a case with in situ carcinoma away from the invasive squamous cell carcinoma of the esophagus. A 58 year-old male was admitted with the chief complaint of swallowing difficulty for a month prior to admission. While we studied the esophagogram and chest CT, we found that the mass was protruded to the lumen of esophagus at the level of the 7th-9th thoracic vertebral columns. We performed esophagectomy with lymph node dissection and esophagogastrostomy by thoracic and abdominal approaches. The pathologic result showed separation of another in situ carcinoma away from the invasive squamous cell carcinoma of esophagus at the level of esophagogastric junctions. Postoperative course was uneventful. Now he is taking the postoperative irradiation at out patient department.

Since the start of the antibiotic era, syphilis has become rare. However, in recent times, it has tended to be prevalent concomitantly with human immunodeficiency virus (HIV) infection and coinfection in North America and Europe. Now, such cases are expected to increase in elsewhere including Korea. A 40-year-old male patient visited hospital complaining of a headache for about one month. Brain computed tomography and magnetic resonance imaging, showed leptomeninged enhancing mass with edema an right porisylvian region, which was suspected to be glioma. Patient underwent a blood test and was diagnosed with syphilis and acquired immune deficiency syndrome. Partial cortical and subcortical resection were performed after small craniotomy. The dura was thick, adhered to the brain cortex, and was accompanied by hyperemic change of the cortex. The pathologic diagnosis was meningovascular syphilis (MS) in HIV infection. After the operation, the patient was treated with aqueous penicillin G. Thereafter, he had no neurological deficit except intermittent headache. At first, this case was suspected to be glioma, but it was eventually diagnosed as MS in HIV coinfection. At this point the case was judged to be worth reporting.

This study was performed to understanding on guidelines for using therapeutic modalities according to injury phases of soft tissue. Clinical decisions on how and when therapeutic modalities may be used should be based on recognition of signs and symptoms. as well as some awareness of the time frames associated with the various phases of the Healing process. The physical therapist must have a sound understanding of that process in terms of the sequence of the various process of healing stage. The results of this study are as follows: 1. Once an acute injury has occured, the healing process consists of the imflammatory response phase, the fibroblastic-repair phase, and the maturation-remodeling phase and can impede by various pathologic factors. 2. Modality use in the initial acute injury phase and the inflammatory response phase should be directed toward limiting the amount of swelling and reducing pain. 3. Modality use in the Fibroblastic repair phase may be change from cold to heat. The purpose of heat is to increase circulation to the injured area to promote healing. 4. During the Maturation-Remodeling phase, some type of heating modalities, ultrasound, or short wave and microwave diathermy should be used to increase circulation to the deeper tissue. In this phases, physical therapists must control training and conditioning habits to allow the injury to heal sufficiently.

Open lung biopsy still has important roles for the marking of diagnosis of diffuse infiltrative lung disease even though transbronchial bronchoscopic lung biopsy and percutaneous needle aspiration biopsy gain popularity nowadays. This is clinical retrospective review of the 56 patients with diffuse infiltrative lung disease undergoing open lung biopsy by minithoracotomy from 1984 to Dec. 1992 in the Department of Thoracic & Cardiovascular Surgery of Catholic University Medical College. 27 men and 29 women, aged 17 to 73 year [mean 49 year , were enrolled & divided into 2 groups;Group A consisted of patients with immunocompromised state [n=19 , Group B patients with non-immunocompromised state[n=38 . Pathologic diagnosis was made in 54 cases[96.4% of these two groups and as follows: infectious; 12 patients[21.4% , Neoplastic; 10 patients[17.9% , granulomatous; 4 patients[7.1% , interstitial pneumonia; 12 patients[21.4% , Pulmonary fibrosis; 8 patients[14.3% , others; 3 patients[5.4% , nonspecific; 5 patients[8.9% , and undetermined; 2 patients[3.6% . Therapeutic plans were changed in 39 patients[69.6% after taking of tissue diagnosis by open lung biopsy. Group B has higher incidence of infectious diseases and change of therapeutic plan than the Group A. The postoperative complications developed in 8 cases[14.3% ,and there is no difference of incidence between the 2 groups. 4 patients belongs to group A, died of respiratory distress syndrome [2 and sepsis [2 which were not related with open lung biopsy procedure. In conclusion, open lung biopsy is a reliable method to obtain a diagnosis in diffuse pulmonary infiltrates and can be performed safely, even in acutely ill, immunosuppressed patients.

Recently we observed and treated a 49-year-old postmenopausal female with enlarged uterine myoma who taking through the hormone replacement therapy(H.R.T). We regard the cause of this case as insufficiency of kidney-yin(腎陰虛), stagnation or the phlegm and pathologic blood(痰瘀阻滯) and H.R.T. ln general cases, myomas grow in size if estrogen and progesterone is present and do not increase in size if estrogen and progesterone levels are low. So if a woman can get to menopause without having symptoms from the myomas, then it is likely that she will never have problems from the growths that require treatment. But Taking postmenopausal estrogen and progestin replacement therapy can cause myomas to grow. So we recommended her to stop the H.R.T. gave herbal-medicine and acupuncture therapy. Thus we could get a good result as follows. The uterine myomas were significantly declined but no change on it's characters. Hot flush and general conditions were also significantly improved And body weight was lessened for about 4.7kg. But vaginal dryness was appeared, So we planed another therapy for that symptom.

Impaction of tooth is a situation in which an unerupted tooth is wedged against another tooth or teeth or otherwise located so that it cannot erupt normally. The supernumerary tooth is also called as hyperdontia and defined as the condition of having additional tooth to the regular number of teeth. The most common supernumerary tooth is a mesiodens, which is a mal-formed, peg-like tooth that occurs between the maxillary incisors. The supernumerary tooth is commonly impacted but they are frequently impacted on maxilla. Ectopic impaction of supernumerary tooth on mandibular condyle, coronoid process, ascending ramus, and pterygomandibular space is very rare condition. In this case, we report a case of impacted supernumerary tooth on mandibular sigmoid notch without definite pathologic change.

Previous studies have introduced the technique of spinous process osteotomy to decompress spinal stenosis, a procedure which aims to afford excellent visualization while minimizing destruction of tissues not directly involved in the pathologic process. However, biomechanically it has not been investigated whether the sacrifice of posterior spinous process might have potential risk of spinal instability or not, even though supra-spinous and inter-spinous ligaments are preserved. Therefore the aim of this study is to evaluate the biomechanical properties after spinous process osteotomy, using finite element analysis. The model of spinous process osteotomy exhibited no significant increase in disc stress or change in segmental range of motion. It is due to the fact that the instability of lumbar spine has been maintained by the two-types of ligaments compared with the prior surgical technique. Therefore, according to the finite element result on this study, this osotetomy was considered to be a clinically safe surgical procedure and could not cause the instability of the lumbar spine.

Among the various diagnostic methods for the voice disorders, video laryngo-stroboscopy is one of the most practical techniques for clinical examination of the vocal fold vibration. It provides valuable informations about the nature of vocal folds' vibration, the extent of pathologic change and data recording for analysis. To obtain the stroboscopic characteristics of several voice disorders, and apply those informations to the diagnosis and management of disorders, we reviewed the stroboscopic findings obtained from the patients with voice disorders at Voice laboratory, the Institute of Logopedics and Phoniatrics form April 1992 to March 1993.

Palatogingival groove (PGG) is an anomaly in the maxillary anterior teeth, often accompanied by the area of bony destruction adjacent to the teeth with no carious or traumatic history. The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. Related diseases can involve periodontal destruction, combined endodontic-periodontal lesions, or separate endodontic and periodontal lesions. Disease severity and prognosis related to PGG depend on several factors, including location, range, depth, and type of the groove. Several materials have been used and recommended for cases of extensive periodontal destruction from PGG to remove and block the inflammatory source and recover the health of surrounding periodontal tissues. Even in cases of severe periodontal destruction, several studies have reported favorable treatment outcomes with proper management. With new options in diagnosis and treatment, clinicians need a detailed understanding of the characteristics, treatment, and prognosis of PGG to successfully manage the condition.
