  • Purpose : To assess the feasibility and the toxicity of the neoadjuvant chemotherapy on the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. Methods and Materials : We analyzed 77 previously untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with neoadjuvant chemotherapy followed by radiation therapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was as follows : AJCC stage III-2, stage IV-75. Sixty-six patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1$\~$5) and cisplatin (100 mg/m$^2$, on Day 1), eleven patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1 $\~$5) and carboplatin (300 mg/m$^2$, on Day 1) as neoadjuvant chemotherapy Prior to radiation therapy. The median follow-up for surviving patients was 44 months. Results : The overall chemotherapy response rates were 87$\%$. The toxicities of chemotherapy were mild. Only 3 patients experienced Grade 3 toxicities (1 for cytopenia, 2 for nause/vomiting). The degree of radiation induced mucositis was not severe, and ten patients developed Grade 2 mucositis. The 5-year overall survival rates were 68$\%$ and the 5-year disease free survival rates were 65$\%$. The 5-year freedom from distant metastasis rates were 82$\%$ and 5-year locoregional control rates were 75$\%$. Conclusion : This single institution experience suggests that neoadjuvant chemotherapy improves overall survival and disease free survival for patients with advanced stage nasopharyngeal carcinoma without increase of toxicity.

  • We present a case of nasopharyngeal stenosis which developed after adenotonsillectomy. A 11-year-old boy underwent adenotonsillectomy because of snoring at a local clinic using a $CO_2$ LASER. After the operation, he cannot breathe via nose due to severe cicatrical nasopharyngeal stenosis. Nasopharyngeal stenosis and oropharyngeal stenosis are rare and challenging problems in the pediatric population. The most common etiology is currently the surgical trauma associated with adenotonsillectomy. Stenosis can vary from a thin band to a complete obstructing cicatrix. Presenting symptoms range from mild hyponasal speech to severe airway obstruction. We treated the patient with velopharyngoplasty using two separate rotational mucosal flaps.

  • Nasopharyngeal stenosis is an obliteration of the normal communication between the nasopharynx and the oropharynx resulting from the fusion of the tonsillar pillars and soft palate to the posterior pharyngeal wall. It is a rare but serious problem. The most common etiology is currently the surgical trauma associated with uvulopalatopharyngoplasty or adenotonsillectomy. It can range in severity from a thin band to a complete obstructing cicatrix, Symptoms vary from mild hyponasal speech to almost complete nasal obstruction with oral breathing, We present a case of a 16 year-old male with nasopharyngeal stenosis after radiofrequency-assisted adenoidectomy in this paper. This patient was managed by synechiolysis, obturator and buccal mucosal graft.

  • Background : Chlamydia pneumoniae is one of common causes in upper and lower respiratory infections. Isolating C. pneumoniae from clinical specimens is very difficult due to the characteristics of the organism. Recently, we succeeded in isolating C. pneumoniae from a Korean patient, who suffered from acute pharyngitis. This is the first isolate from a clinical specimen in Korea. Methods : We attained a nasopharyngeal swab from a 22-year-old female patient, and inoculated it on a monolayer of the Hep-2 cell line. After 8 passages, we found the inclusion bodies of C. pneumoniae by an immunofluorescence(IF) test. The species-specific monoclonal antibody IF staining and species-specific PCR were done to confirm the species of the isolate, and electron microscopy was used to characterize the morphology. Results : The isolated was confirmed to be C. pneumoniae by species-specific IF and PCR, and the strain was named LKK-1. The shape of the elementary body was round and with a narrow periplasmic space, as shown by electron microscopy, which is similar to the Japanese strain, but not the Western strain. Conclusion : We succeeded in isolating C. pneumoniae from a 22-year-old patient with acute pharyngitis, which is the first isolate in Korea. In the future, this Korean strain will be useful to the study of C. pneumoniae.

  • For patients receiving chemotherapy and radiation therapy treatment progresses as vomiting, nausea, weight of the patient because of a loss of appetite it is reduced. The patient's weight and the distance from the skin and the treatment site is expected to be closer, thereby reducing the change in the skin because of this dose. This study tests using a loose see the difference between the volume change appears as the weight of the patient using the same phantom and the phantom body of the patient. To using the same as the position EBT film is attached to the skin of the treatment site and was adjusted to the thickness of the Bolus. And using a computerized treatment planning only tomotherapy equipment was passed under the conditions according to the thickness of the radiation dose. To baseline for accurate reproduction position using the MVCT was applied to treated with verification. By passing a total of three dose reduced the error, it was a measure of the film by using a dedicated scanner, EBT VIDAR scanner. Got an increase in the skin dose is displayed each time the thickness of the bolus reduced, in a bolus was completely removed with the highest value. If the changes appeared dose was greater weight loss patients to chemotherapy and therefore bolus thickness variation considering the weight loss of the patient when applying the tomotherapy of nasopharynx cancer was found that the increase in skin dose be increased. This large patient before treatment due to weight loss over the image verification is considered to be established should consider how to re-create your mask and treatment plan for fixing it.

  • Purpose: Cricopharyngeal incoordination is a rare cause of swallowing difficulties in newborns and infants; it is characterized by delayed pharyngeal contractions related to cricopharyngeal relaxation. Dysphagia and repeated aspiration are common findings despite normal sucking. We conducted this study to assess the clinical features of cricopharyngeal incoordination in newborns and infants. Methods: An analysis of the clinical data from 17 patients with cricopharyngeal incoordination who were admitted to the Department of Pediatrics, Pusan National University Hospital, between 2000 and 2006 was conducted retrospectively. The diagnosis of cricopharyngeal incoordination was established by the clinical characteristics and the videofluoroscopic swallowing studies. Results: The male to female ratio was 1:1.1 (males 8, females 9) the age range 1 to 60 days. The body weight of 11 patients (64.7%) was less than the $10^{th}$ percentile at diagnosis. Six patients (35.3%) were born prematurely. The associated anomalies or diseases were chromosomal anomaly (2 cases), congenital heart disease (3 cases), and laryngomalacia, hypoxic brain damage or neonatal seizures (1 case each). The chief complaints of patients were recurrent aspiration pneumonia (10 cases), feeding difficulty (9 cases), dyspnea (4 cases), and chocking (4 cases). The severity of aspiration on the videoesophagogram or esophagogram was mild in 12 cases. The correlation between the severity of aspiration and the duration of tube feeding after the diagnosis was significant (p<0.05). Conclusion: Cricopharyngeal incoordination should be considered in the differential diagnosis of newborns and infants, without known risk factors associated with swallowing dysfunction, when they present with unexplained respiratory problems. Although the prognosis of cricopharyngeal incoordination is good, early diagnosis and tube feeding are recommended to prevent the complications associated with this disorder.

  • Epithelial-myoepithelial carcinoma is rare, low grade malignant tumor of the salivary glands that exhibits a dual composition of epithelial and myoepithelial cells. Most of these tumors arise in the parotid gland, and only few occur in the submandibular gland or minor salivary glands. We describe here a rare case of epithelialmyoepithelial carcinoma arising from a minor salivary gland in the nasopharynx, one of the most unusual locations. The clinical and biological behavior of this tumor is not yet known.
