Background and Objectives : In order to evaluate the result of the $CO_2$ LASER laryngomicrosurgery for the treatment of glottic stenosis after inhalation injury. Patients and Methods : We retrospectively evaluated 7 patients with inhalation injury on larynx who received their surgical treatment at the Severance hospital on Jun. 2003. The average follow-up duration was 64.9 days and they were 3men and 4women. The average patient age was 30.1 years, We evaluated the preoperative state with neck CT and stroboscopy. The operation was $CO_2$ LASER laryngomicrosurgery and Mitomycin-C application. The postoperative state was evaluated with stroboscopy at POD#6 and POD#2months. Results : 6 patients had the intubation as the first care on accident. All 7 patients showed the glottic web and after operation, the vocal cord seemed to be almost normal. The glottic area was widened as 3 times as the preoperative state at POD#6. Conclusion : We could lessen the symptoms like dyspnea and hoarseness with laryngomicrosurgery and Mitomycin-C application for patients complaining some laryngeal problems because of the inhalation injury.

CT guided percutaneous fine-needle aspiration (FNA) of the liver for both cytologic and histologic examination has great value in diagnosing liver malignancy. From March, 1986 to April, 1990, 62 patients with the clinical impression of liver malignancy underwent CT guided percutaneous FNA biopsy. Of these, 43 cases were reviewed for this study, 19 were reported to be liver cell carcinoma, 2 were adenocarcinoma, 11 were reported as anaplastic cell present, and the rest (11 cases) were negative (9) or necrotic (2). Among the 11 cases of the last group, 9 were diagnosed as liver cell carcinoma and 2 were necrotic histologically. Retrospective review, in order to clarify the cause of cytologic diagnostic error, of both cytologic and histologic slides of all cases showed discordance of 23% between these diagnoses and sensitivity is 93.9% and specificity is 90.9%. The reasons were as follows ; 1) the lack of awareness of tumor cells of well differentiated liver cell carcinoma (4 cases), 2) missed tumor cells due to too scanty cellularity (1 case), 3) improper smear (2 cases) and no tumor cell In the cytologic smears (3 cases). In such cases, at the initiation of FNA, a correct diagnosis of liver malignancy could only be made by a combination of cytologic and histologic examinations. However after three years' experience we can conclude that cytomorphologic features of liver cell carcinoma are sufficiently distinctive from other liver malignancies to be diagnostic.

A total of 48 cases of tuberculous lesion in the lymph nodes (43 cases), lung (3 cases) and soft tissue (2 cases), was subjected to fine needle aspiration cytology (FNAC). The age of the patients ranged from 19 to 77 year-old (average 33.6 years in age) and the male to female ratio was 1 : 4. Thirty-four cases (70.8%) demonstrated distinct granulomatous reaction with or without caseation necrosis, nine cases (18.8%) showed no granulomas, but large amount of necrotic debris with numerous polymorphonuclear cells and histiocytes, and five cases (10.4%) revealed acellular material only. The overall AFB positivity in smears was 62.5%. In areas associated with granulomatous reaction and necrosis, AFB positivity was 55.8%, while it was 80.0% in cases with acellular necrotic material. There were 2 cases of parasitic infestation which could not be easily differentiated from tuberculosis based on aspiration smears only.

Purpose: Concept analysis was performed on the behavioral concept of endotracheal suctioning (ETS), to identify the goal, to develop astandardized clinical protocol, to identify the antecedents and consequences, and to differentiate the improper use of ETS. Method: Walker & Avant's concept analysis was employed using clinical guidelines, books and review articles in which the procedures of ETS were written in detail and published in Pubmed within the last 20 years. Result: The macro-goal of ETS was to remove accumulated respiratory secretions. Three defining attributes of ETS were identified; catheter, suctioning and asepsis. Each attribute involved empirical referents, such as the size and depth of the catheter, the suction pressure, duration and method for suctioning. The antecedents of ETS were identical to the clinical evidences for the need of ETS such as the nursing assessment data. The consequences of ETS serve as an evaluation criteria on the effectsof ETS based on the goal of ETS. Conclusion: The concept analysis of ETS demonstrates an example of considering a specific nursing protocol of ETS as a behavioral concept, applying concept analysis to it to identify it's key behavioral components as defining attributes and empirical referents and then developing and applying the standard ETS protocol.

The fine needle aspiration (FNA) cytology findings in 19 cases of primary neoplasia of the pancreas are reported. The aspirates were obtained under ultrasound guidance in 16 cases and under direct vision intraoperatively in three cases. These cases represented 79% of 24 diagnoses in a series of 30 pancreatic FNAs. Of these 30 cases no cytologic diagnoses were made in six cases (20%) because of insufficient or inadequate samples The cytologic diagnoses were confirmed by histologic examination following resection or biopsy of the tumors. The diagnoses included 9 duct ceil adenocarcinomas, 1 mucinous adenocarcinoma, 2 mucinous cystadenocarcinomas, 1 acinar cell carcinoma, 1 papillary cystic tumor 3 islet ceil tumors, 1 neuroendocrine carcinoma and 1 leiomyosarcoma. The cytologic features of the neoplasia were detailed and the differential diagnosis was discussed. The important criteria for the cytodiagnosis of pancreatic tumors were reviewed. This review leads us to think that nonoperative (percutaneous) cytologic approaches to the diagnosis of pancreatic tumor are advantageous for the management of patients, and that correct cytologic diagnosis with pancreatic FNAs can easily be made, if adequate samples are obtained.

A number of studies have shown the value of fine needle aspiration cytology for the diagnosis of breast lesions, but reports on the comparison of cytologic and histologic variations of breast cancers are few. We reviewed histologically proven 106 breast aspirates with an emphasis on the cytology of ductal carcinomas and of an area of uncertain atypia. Positive and negative predictive values of breast aspiration cytology were 100% On review of the cases originally diagnosed as atypia of uncertain nature (19 %), features more suggestive of malignancy or benignancy were recognizable in most underdiagnosed cases and a half of overdiagnosed cases, respectively. However, indistinguishable atypism also remained. Thirty seven cases out of 53 infiltrating duct carcinomas revealed malignant cytology, with variations in background, cellularity, morphology of cell groups, and extent of isolated tumor cells. When classifying the infiltrating duct carcinomas into scirrhous, solid-tubular, and papillotubular types, scirrhous type frequently appeared as irregularly shaped tight or loose cell clusters, and solid-tubular type as round-margined cell balls.

후두낭종은 후두소낭의 비정상적인 팽창으로 발생하는 드문 질환이다. 후두낭종의 크기와 증상에 따라 치료 방법은 단순 경과관찰에서부터 흡인, 경화제 주입, 수술적 치료까지 다양하다. 수술적 치료는 외적 접근법, 내시경적 접근법 또는 두 접근법을 혼용한 접근법을 통해 이루어진다. 최근 저자들은 경부 외적 접근법 및 연골막하 절제를 통한 혼합 후두점액낭종 1예의 치료를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Fine needle aspiration cytology as a diagnostic workup of parotid gland tumor is a simple and useful method. Although fine needle aspiration cytology could not predict accurate diagnosis in all cases, it is usually helpful in differentiating malignancy and benign lesions. A 35-year-old female was found to have a parotid mass for 1 year. Preoperative evaluation including computed tomography and magnetic resonance imaging were non-diagnostic, but, fine needle aspiration cytology on parotid mass showed the suspicion of a low-grade mucoepidermoid carcinoma. Superficial parotidectomy and selective neck node dissection were done based on cytology. However, final pathological examination confirmed benign pleomorphic adenoma. Here, the diagnostic accuracy and cautions in interpretation of result of fine needle aspiration cytology is discussed with respect to the case.
