Background Infantile hemangioma (IH) is a common vascular tumor in pediatric patients, and is commonly treated with propranolol. We describe our experiences with dosage, response to treatment, and side effects in 23 IH patients treated with propranolol. Methods For this nonrandomized comparative cohort study, the authors enrolled 23 patients treated with propranolol. Photographs were taken before propranolol administration and at 3, 6, 9, and 12 months after treatment. Treatment responses were objectively analyzed with a computer program. Results There were three male and 20 female patients. Common tumor locations were the head and neck (13 cases, 56.5%), trunk (four cases, 17.4%), extremities (three cases, 13.0%), and combined locations (three cases, 13.0%). The response to propranolol was significantly lower in patients with two or more lesions than in patients with a single lesion in terms of both color fading (P<0.001) and size reduction (P<0.001). In male patients ($42.2{\pm}3.9$), the change in a-values, indicating coloration, was higher than in female patients ($19.8{\pm}13.8$) (P<0.001). In patients who started treatment before 6 months after birth, the size reduction was greater than in their counterparts (62.3%; range, 3.0%-93.0% vs. 15.8%; range, 1.0%-79.0%; P<0.001). Conclusions Propranolol is an efficacious treatment with a good safety profile. In patients with a single lesion, the response to treatment was better in terms of color fading and size reduction. Furthermore, male patients responded better to propranolol treatment in terms of color fading than female patients, and starting treatment before 6 months after birth was more advantageous for size reduction.

외상에 의한 영구치의 손상은 소아와 청소년기에 많이 발생하며, 특히 상악 중절치가 가장 많이 손상을 받는 것으로 알려져 있다. 그 중 치관 파절은 영구치열에서 25-76%의 빈도로 나타나며, 이러한 치관 파절시 심미적, 기능적으로 만족스러운 수복을 하기 위한 다양한 노력이 시도되어 왔다. 성인에서 영구 전치 치관 파절이 발생한 경우에는 도재 소부 전장관, 라미네이트 등의 보철적 치료로 심미적인 수복이 가능하지만, 미성숙 영구 전치의 파절이 발생한 경우에는 치근 성장이 완료되지 않아 보철적 치료가 힘들고, 근관 치료가 필요한 경우 근관 치료를 완료하는데도 오랜 시간이 소요된다. 따라서 이러한 경우 과거에는 교정용 밴드, 기성 금속관, 글래스 아이어노머 시멘트 등을 이용한 수복이 시행되었는데, 심미적으로는 만족스러운 결과를 얻지 못하였다. 그러나 근래에는 수복 치과재료의 발달로 파절편을 재부착하거나, 광중합 복합 레진 수복을 통해 심미적 수복이 가능하게 되었다. 본 증례들은 경북대학교 치과병원 소아치과에 외상에 의한 상악 중절치 파절을 주소로 내원한 환아들로, 적절한 치수 처치 후, 치아 파절편 부착과 복합 레진 수복을 통해 심미적으로 양호한 결과를 얻었기에 이를 보고하고자 한다.

The ecosystem of Jaemin stream, flowing into the center of Gongju-si, had been damaged by low water quality and lack of water quantity of the steam. However, after applying the SSB (Sustainable Structured wetland Biotop) system to the flood plain and the upstream of Jaemin stream, the efficiency of ecological water purification and ecological restoration are as follows. Through the constant maintenance and monitoring from year 2009 to year 2013 after restorative design and construction the average influent concentration of BOD5 was 4.2 mg/L, and the average effluent concentration was 1.8 mg/L, reaching ecological water purification rate of 57%. As for the T-N, the average influent concentration was 9.983 mg/L, and the average effluent concentration was 6.303 mg/L, showing the rate of 37%. For the T-P, the average influent concentration was 0.198 mg/L, and the average effluent concentration was 0.098 mg/L, being the rate of 51%. The vegetation of Jaemin stream monitored for 2 years after the restoration was composed of 51 species in 28 families which show high ratio of planted native species. As for the animals in the site, 5 species in 3 families of reptiles and amphibians, 34 species of 23 families of birds, and 3 species in 2 families of mammals were monitored, indicating that the bio-diversity of the site has improved, as well.

Purpose: Multiple symmetric lipomatosis (MSL) is a relatively rare disorder characterized by presence of multiple, symmetric, nonencapsulated fat masses in face, neck, shoulder and other areas. There has been only a few cases reported in Korea. The main purpose of this research is to examine the Korean patients to see what kinds of special characteristics occurred due to this disease and to decide the proper treatment.Methods: A total of 16 patients were evaluated retrospectively. 5 patients were treated at our hospital. The other patients were reviewed from literature. We analyzed the biological characters of patients, location of fat deposit, morphologic characters of patients, clinical evidence of neuropathy, associated metabolic disorders and treatment modality.Results: All cases were male patient. The mean age of onset was 47.43 years. All patients were moderate to heavy alcoholics. The most common location of fat deposition was posterior neck and abdomen. In neurologic exam of 9 patients, 5 patients showed muscle weakness, tremor, pain and autonomic nerve dysfunction. In metabolic studies of 9 patients, total cholesterol values were higher in 1 patient. A glucose tolerance test was abnormal in 1 patient. In treatment modality, 14 patients were treated with surgical resection, 1 patient was treated with liposuction and surgical excision, 1 patient was treated only with liposuction. Conclusion: To treat MSL patients successfully, we should concentrate not only on the removal of the fatty tissue but also on neurologic abnormities, metabolic disorders and associated diseases.

The purpose of this study is to effectively treat low back pain for the out patients who have been treated at the oriental hospital. Sorting the low back pain patients into four types based on scapular and ilium tilting hyper/hypo mobility characteristics, it has used several kinds of acupuncture stimuli on the 4 motor points of limb skeletal muscles, analyzing the acupuncture treatment on the 12 acupuncture points with which oriental hospitals has given to the low back pain patients and comparing with this effect. It has been analyzed how effectively the acupuncture stimuli has been contributed to the low back pain patients who suffered from skeletal muscles of spinal limb thorax abdominal and spinal skeletal system. The results are as follows. 1. There has been changes after treatment in both the control and experimental groups for low back pain patients, but the latter has been more increased in changes than the former. 2. There were much effects on the balanced restorations for spinal skeletal muscle in both the control group and experimental one, but on terms of restoration degree, the degree of the experimental group was higher than that of the control group. 3. Both the contrastive treatment and the experimental one have been contributed to the balanced restoration for all of the limb thorax abdominal muscles, but there were a few differences in terms of the way for restoration and the effects for improvement according to body types. 4. On both the control and the experimental group, spinal skeletal system has been restored with balance, but the experimental group has been higher effective on the balanced restoration than the one of the control group. Considering these results both the control and the experimental treatments have been contributed to the balanced restorations for all of low back pain patients who were suffering from skeletal muscles of spinal limb thorax abdominal and spinal skeletal system, but the contribution degree for the experimental group has been higher than that of the control group.

Purpose: The rate of fistulas occuring followed by resection of oral cavity, oropharyngeal, hypopharyngeal, and laryngeal cancer are reported to be 9 ~ 23% according to various documents. Neglected treatment of the fistula can result in a setback in proper treatment with restrictions in oral intake leading to delayed return to daily life. Furthurmore, in severe cases, it may injure important vessels and adjacent structures of the neck area. The author reviewed previously reported cases of treatment methods for fistulas recurring after diverse head and neck operations and with sharing the treatment experiments of our patients, we tried to present a treatment algorism for different fistula types. Methods: Our study was based on retrograde analysis of 64 patients who were clinically diagnosed with fistula after operation for cancer of the head and neck from 1997 to 2008 at Severance Hospital. Their primary sites of cancer were 8 oral cavity, 22 oropharynx, 25 hypopharynx, and 9 larynx. The patients were aged 45 to 75 years and the male to female ratio was 11 to 1. The patient's operation records and progress notes were evaluated for determination of degree of fistula and treatment methods. Results: Most fistulas were clinically suspected after postoperative 5 days and symptoms noted for detection of the fistula were erythema, purulent discharge, edema, tenderness, and fluctuation. The fistula was definitely diagnosed at postoperative 2 weeks with barium test and treatment method ranging from conservative management to operative procedure were applied to each patients. Total 21 patients were managed with conservative protocol. In 15 cases, direct repair of the fistula was done and more stable repair of the fistula was possible with using of TachoComb$^{(R)}$. Pharyngostoma was performed in 14 patients. Among them, 4 patients healed spontaneously, 5 patients were taken direct closure, 4 patients were taken pectoralis major musculocutaneous flap, and one patient was taken esophageal transfer. The other 14 patients were taken 11 pectoralis major musculocutaneous flaps and 3 free flaps without pharyngostoma formation. Conclusion: Fistula is a troublesome complication resulting after resection of head and neck cancer. Early detection and adequate treatment according to the period and condition of the fistula may prevent further complications and reduce the pain of the patient.

This case report describes a technique in which endodontic treatment and permanent indirect restoration were completed in the same clinical appointment with the aid of a computer-aided design/computer-aided manufacturing (CAD/CAM) system. Two patients were diagnosed with irreversible pulpitis of the mandibular first molar. After access preparation, root canals were located, irrigation was performed until bleeding ceased, and the coronal tooth structure was prepared for indirect restoration. Then, utilizing an interim 3-mm build-up of the endodontic access cavity, a hemi-arch digital scan was performed with an intraoral scanner. Subsequent to digital scanning, restoration design was performed simultaneously with the endodontic procedure. The root canals were shaped using the Race system under irrigation with 2.5% sodium hypochlorite followed by root canal filling. The pulp chamber was subsequently filled with a 3-mm-thick composite resin restoration mimicking the interim build-up previously utilized to facilitate block milling in the CAD/CAM system. Clinical try-in of the permanent onlay restoration was followed by acid etching, application of a 5th generation adhesive, and cementation of the indirect restoration. Once the restoration was cemented, rubber dam isolation was removed, followed by occlusal adjustment and polishing. After 2 years of follow-up, the restorations were esthetically and functionally satisfactory, without complications.
