Factors associated with development of complications after endoscopic foreign body removal

We analyzed the clinical characteristics of patients who underwent endoscopic foreign body removal and the risk factors of complications. The medical records of 415 patients treated from January 2000 to August 2011 for suspected foreign bodies were retrospectively reviewed. Patient characteristics, endoscopic findings, clinical outcomes, and risk factors of complications were analyzed. Foreign bodies were detected endoscopically in 315 patients. Fish bone fragment [36.9%] and coins [15.3%] were the most common type of foreign bodies in adults and children, respectively. Complications associated with endoscopic procedure occurred in 26 patients [8.3%]; 20 of the patients were treated conservatively and the other six patients underwent surgical treatment. Perforation [14%] was the most common complication. By univariate and multivariate analysis, the risk factors associated with complication after endoscopic foreign body removal were long duration from ingestion to endoscopy [P = 0.009] and existence of initial mucosal injury [P = 0.018]. Most foreign bodies were successfully removed by endoscopy without complication, but long duration from ingestion to endoscopy and mucosal injury were risk factors of complications of endoscopic foreign body removal. Patients with these risk factors could require more careful treatment

A Case of Type 1 von Hippel-Lindau (VHL) Disease associated with VHL Germline Mutation / 대한내분비학회지

Von Hippel-Lindau (VHL) disease is an autosomal dominant neoplasia syndrome that result from a germline mutation in the VHL gene. Germline mutation in the VHL gene lead to the development of hemangioblastomas of the central nervous system and retina, cysts and clear cell carcinoma of the kidney, cyst adenomas of other organs, and pheochromocytoma. VHL is a tumor suppressor gene on the short arm of chromosome 3. VHL disease has been classified into two main clinical subtypes depending on the presence (type 2) or absence (type 1) of pheochromocytoma. Type 2 has been subdivided into three categories depending on the presence (type 2B) or absence (type 2A) of renal cell carcinoma, with type 2C being a rare subtype in which pheochromocytoma is the sole manifestation of VHL disease. Recently we experienced a family with VHL type 1 who carry C to T (Q73X) transition in codon 217 nonsense germline mutation in exon 1 of VHL gene. The authors report this case with literature review.

Bronchoscopic Electrocautery with Electroprobe and Diathermic Snare in Patients with Malignant Airway Obstruction / 결핵및호흡기질환

BACKGROUND: Endobronchial tumors cause?life-threatening dyspnea and can lower the quality of life due to central airway obstruction.?In those cases with an intraluminal tumor, various bronchoscopic techniques are available for tumor debulking. The therapeutic effect of bronchoscopic electrocautery for palliation in patients with a symptomatic tumor obstruction was studied. METHOD: Nineteen patients with bronchogenic carcinomas (n=15) and metastatic tumors affecting the bronchi (n=4), between March 2002 and March 2005, were enrolled in this study. Electrocautery was performed under local anesthesia using an electroprobe and diathermic snare. Using flexible bronchoscopy, a follow-up bronchoscopic examination was performed 3-4 days later. Symptom improvement was evaluated by FEV1, FVC and dyspnea score (Modified Borg Category Scale (0~10)), both before and after the electrocautery. RESULTS: The success rate of electrocautery on the follow up examination was 84%. Patients with endoluminal airway lesions had a mean overall decrease in the size of the obstruction to 47.8+/-15.7%. The mean Improvement in the dyspnea score immediately after the endobronchial tumor debulking was 2.78+/-1.42.The average improvements in the FEV1 and FVC after electrocautery were 0.32+/-0.19L and 0.5+/-0.22L, respectively. There were 2 cases of complications related with electrocautery (one each of pneumothorax and pneumonia). CONCLUSION: Electrocautery using an electroprobe and diathermic snare was an effective and safe palliative treatment for a symptomatic endoluminal airway obstruction in lung cancer.

Changes of root length and crestal bone height before and after the orthodontic treatment in nail biting patients / 대한치과교정학회지

Although the purpose of orthodontic treatment is to increase the function and esthetics of the jaws along with increasing stability, there are many side effects during the treatment itself, such as root resorption and alveolar bone resorption. Such resorption of the apical root is unpredictable, and may even proceed into the dentin layer. Once the process has begun, it is irreversible. By evaluating the effect of many oral habits, especially that of nail biting, in correlation with the root and the periodontal tissues, the appropriate biomechanics for orthodontic treatment can be taken into consideration, along with the possibility of root resorption and alveolar bone loss during orthodontic treatment, and any legal problems that might occur. Among the male and female patients of the ages 10~15 without skeletal deformity, 63 were chosen as the experiment group with known nail biting habits at time of examination, and within the same age group without nail biting habits as the control. After the orthodontic treatment, number of the experiment group was 31 and the control group was 22. The periapical radiographies of anterior teeth were taken and the assesment of the root length and alveolar bone level were taken before(T1) and after(T2) the orthodontic treatment. The results from this study were as follows : 1. Before the orthodontic treatment, average crown-to-root ratio of the experimental group showed noticeably high values in 4 maxillary incisors and mandibular right central incisor. 2. Before the orthodontic treatment, comparing the root length, maxillary and mandibular right central incisors and both mandibular incisors had a smaller value in the experimental group. 3. Before the orthodontic treatment, comparing and evaluating the alveolar bone loss measured from the cemento-enamel junction to the alveolar bone crest, some crestal bone of the experiment group showed greater loss than the control. 4. After the orthodontic treatment, there was shortening of the root length and loss of the crestal bone in both groups. 5. After the orthodontic treatment, the changes of C/R ratio and the shortening of root length were significantly high in the experimental group. 6. After the orthodontic treatment, the level of alveolar crestal bone showed greater loss in the experimental group.
