As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Nasopharyngeal angiofibroma is a relatively rare, but is a well known tumor that occurs almost in male, most frequently during the adolescent stage. Its character is histologically benign but clinically malignant because of locally invasive character to the adjascent structures, massive bleeding tendency during surgical procedure and high recurrence rate after treatment. Recently many advancements diagnostic method and surgical technique has reached satisfactory result in treating this difficult tumor. The authors present a case of nasopharyngeal angiofibroma in 16 years old male patient, who was received surgical removal of the tumor through the transpalatal approach after full diagnostic evaluation and preoperative hormonal therapy.

Ketotifen, a benzocycloheptathiophene, has an orally effective antiallergic as well as antihistaminic properties. In pervious studies, Ketotifen has shown encouraging results on patient with allergic rhinitis, either perennial or seasonal. 39 patients with allergic rhinitis had been treated with Ketotifen 1 mg twice daily for 8 weeks. And we obtained following results. 1) The efficacy rate in sneezing attack was 73.5%, in nasal discharge 71%, in nasal obstruction 58%. 2) Some improvements in at least one of three-major symptoms were noted within 1 week in 30.7%, within 2 weeks in 55.8%, within 3 weeks in 66.7%, within 8 weeks in 87.2%. 3) Physical findings such as colour, swelling of turbinate, character of rhinorrhea were not improved significantly. 4) Side effect was observed only in one patient with abdominal pain and diarrhea, which was subsided after interruption of administration. These results suggested that Ketotifen was effective in treatment of allergic rhinitis.

In 1962, a case of “generalized skeletal dysplasia with multiple anomalies” was reported by Taybi as a new clinical syndrome. The most characteristic features of the syndrome seemed to be hearing loss, cleft palate and peculiar digital anomalies, so, the syndrome designated as otopalatodigital syndrome by Dudding, et al. Recently, the authors have experienced a case of OPD syndrome who visited Yeungnam University Hospital with the chief complaint of hypernasality, and underwent pharyngoplasty for correction of VPI. We present here a new case and review the literature on the subject.

OBJECTIVE: The purpose of this study was to evaluate the outcome and safety of vaginal delivery after previous cesarean birth. METHODS: This study was based on 303 cases of delivery with previous cesarean birth at Masan, Fatima Hospital from May, 1997 to April, 1998. Among them, 62 cases had performed trial of labor. We had made a comparison between elective repeat section group and trial of labor group by analizing the frequency, successful rate, maternal morbidity, perinatal morbidity and mortality. RESULTS: Among 303 cases with previous cesarean birth, trial of labor was done in 62 cases(20.5%). Among trial of labor group, vaginal delivery was done in 54 cases (87.1%) and repeat section was done in 8 cases(12.9%). Indications for elective repea section before the onset of labor were refuse trial of labor(51.9%), request for tubal ligation(17.4%), and previous section > or =2(7.5%), etc. The successful rate of vaginal delivery according to indication for previous cesarean birth was 85.0%(17/20) in the cases of dystocia and 88.1%(37/42) in the cases except dystocia. The successful rate was not influenced by the indication for previous cesarean birth(P>0.05). There were no maternal death or uterine rupture in the cases of trial of labor. There were no significant difference between elective repeat section group and trial of labor group in maternal morbidity, perinatal morbidity and mortality(P>0.05). CONCLUSION: Under strict indications, vaginal delivery subsequent to cesarean birth may be safe, and can reduce the rate of cesarean section that was increased constantly.

BACKGROUND: Cyclin-dependent kinase (CDK) inhibitors are family of molecules that regulate the cell cycle. The CDKN2, a CDK4 inhibitor, also called p16, has been implicated in human tumorigenesis. The CDKN2 inhibits the cyclin/CDK complexes which regulate the transition from G1 to S phase of cell cycle. There is a previous report that homozygous deletion of CDKN2 region on chromosome 9p21 was detected frequently in astrocytoma, glioma and osteosarcoma, less frequently in lung cancer, leukemia and ovarian cancer, but not detected in colon cancer and neuroblastoma. However, little is known about the relationship between CDKN2 and laryngeal cancer. Therefore this study was initiated to investigate the role of CDKN2 in human laryngeal squamous cell carcinoma development. MATERIALS AND METHODS: We used 5 human laryngeal carcinoma cell lines whether they have deletions or losses of CDKN2 gene expression by DNA-PCR or RT-PCR, respectively. We examined 8 fresh frozen human laryngeal cancer tissues to detect the loss of heterozygosity (LOH) of CDKN2. PCR was performed by using microsatellite markers of short arm of human chromosome 9 (D9S126, D9S144, D9S156, D9S161, D9S162, D9S166, D9S171, D9S200 and D9SIFNA). For informative cases, allelic loss was scored if the signal of one allele was significantly decreased in tumor DNA when compared to the same allele in normal DNA. RESULTS: The CDKN2 DNA deletion was observed in 3 cell lines. The CDKN2 mRNA expression was observed in only one cell line, which was very weak. LOH was detected in 7 cases (87.5%). CONCLUSION: These results suggest that CDKN2 plays a role in the carcinogenesis of human laryngeal squamous cell carcinoma.

The operative methods for the choanal atresia or stenosis are transseptal, transnasal, transpalatal and transmaxillary approaches. Among them, endoscopic transnasal approach provides excellent visualization and little age limitation. The use of CO2 laser in the management of choanal atresia enables the accurate incision and vaporization. We experienced a case of acquired bilateral choanal stenosis which developed after external irradiation for nasopharyngeal carcinoma. She presented with the symptoms of slowly progressive bilateral nasal obstruction and persistent nasal discharge for the past three years prior to visiting hospital. We successfully managed her by endoscopic transnasal repair with CO2 laser and found this technique to safe and simple.

Most malignant lesions of the middle ear and mastoid cavity are usually originated from the epithelium. The squamous cell carcinoma accounts for 75-90% of all malignant tumors in this localization. However, malignant lymphoma of the middle ear cleft is very rare condition and usually occurs as an extension from the temporal bone, affected along the other organs in generalized lymphoma. Also, primary presentation of malignant lymphoma in the middle ear cleft is very extremely rare and only seven cases could be traced in the available literature2)5)6)11)12)13)14). We present a very rare case of diffuse large cell type non-Hodgkin's malignant lymphoma with primary presentation in the middle ear cleft in 30 year-old male patient. So, the authors first report a case of malignant lymphoma of the middle ear cleft in Korea with review of literature.

Different techniques for culturing respiratory epithelial cells have been developed to overcome the limitations of studies on in vivo and on bioptic material. Traditionally, culture systems are divided into organ cultures, explant cultures and dissociated cell cultures. The first two contain both epithelial and non-epithelial cells. However, in monolayer cultures of dissociated cells only epithelial cells are present, the effects observed are caused by a pure epithelial responses. The purpose of this study is to establish primary culture method of human nasal epithelium (HNEC) by monolayer culture of dissociated cells to evaluate the role of the epithelial cells in the allergic and non-allergic nasal inflammatory reactions. HNEC was prepared by primary culture method of monolayer culture of dissociated cells from human inferior nasal turbinate mucosa of septal deviation patients. Primary cultured cells were characterized by indirect immunofluorescence assay and transmission electron microscopy. The immunoreactivities of cytokeratin-pan and cytokeratin No. 8 were observed in cultured HNEC. However, the immnoreactivities of vimentin and von Willebrand factor were not observed in cultured HNEC. The tonofilaments and desmosome were observed in cultured HNEC. The cultured epithelial cells were identified to be pure nasal epithelial cells. The monolayer culture of dissociated cells could successfully be employed for further study to investigate the role of the epithelial cells in allergic or non-allergic nasal inflammatory diseases.
