The chronic paranasal sinusitis are caused by various orign such as dental, general and anatomic problem. Among them, the odontogenic maxillary sinusitis which concerned by cral & maxillofacial surgeon have been treated by medicine, conservative treatment such as endodontic treatment, and Caldwell-Luc operation. But, New technique, so called Functional Endoscopic Sinus Surgery, have recently been performed in the ENT dept. This technique have the mechanism that widening maxillary ostium through removal of involved nasal mucosa and adjacent tissue accelerates adequate drainage and regeneration of normal mucosa and have merits such as minimum morbidity and complication. So, we would report one case, 22 years old female, of 3 patents who were diagnosed as odontogenic maxillary sinusitis and treated by Functional Endoscopic Sinus Surgery and Apicoectomy, and had good results.

The Pumping technique generally has been known as a diagnostic method that predicts intracapsular status and selects required evaluation and treatment. But, in addition to this indication, when it is followed by Lavage and Manipulation technique, this may be used as therapeutic method that is effective on Closed Lock with limited mouth opening and pain. Therefore, we examined results of this technique abut Closed Lock and would like to report therapeutic effects of Lavage and Manipulation technique. We selected 40 patients of 200 patients diagnosed as Closed Lock over 53 months from SEP. 1991 to PEB. 1996, who were possible follow-up and performed by Lavage and Manipulation technique. Appraisal between pre-procedure and post-procedure was performed just after procedure, in 1 month and in 3 months, and therapeutic effects were divided by marked, useful, a little useful and ineffective. As a result, Lavage and Manipulation technique had remarkable increase of maximum mouth opening(>5mm) in 39 persons(98%) just after proceure, 36 persons(90%) in 1 month, and 39 persons(98%) in 3 months, and subsided pain completely just after procedure and had remarkable decrease of pain in 30 persons(75%) in 1 month, 32 persons(80%) in 3 months. So we concluded that the Lavage and Manipulation technique is effective therapy of Closed Lock which can be used with ease.

The incidence of multiple primary malignancy is extremely rare although the prevalence rate is increasing recently. There are several reasons of increment of multiple primary malignancy. First, the advances in the treatment and the diagnostic modality of malignancy have led to increased survival rate. So many of the patients who survived the first cancer could live long enough to develop additional primary cancers. Second, the long term effects of chemotherapy and radiation therapy have been proved oncogenic. Third, increasing age, environmental carcinogen, some kinds of viral infection, and genetic predisposition have potentials for multiple carcinogenesis. Most of multiple primary cancer is double primary, however triple primary cancer is rare. We experienced a case of triple primary cancer involving endometrium, colon, and stomach. We report this case with a review of literatures.

BACKGROUND AND OBJECTIVES: Quinolone-induced arthropathy is an unusual toxic effect observed in juvenile animals of multiple species. Such toxic effects are usually found in joint cartilages. The reports of chondrotoxic potential of quinolones in juvenile animals were mainly performed in weight bearing joints such as hips and knees. The purpose of this study was to investigate the morphological changes in the incudomalleolar joint of immature rats dosed with ciprofloxacin, and to draw relationship between the incudomalleolar joint pathology and hearing. MATERIALS AND METHODS: An experimental group of 21-day-old rats were administrated intraperitoneally with 200 mg ciprofloxacin/kg for 10 days. The hearing threshs of the control and experimental animals were determined with auditory brainstem response (ABR). Their ossicles were obtained and fixed, and we observed them with light microscopy (LM) and transmission electron microscopy (TEM). RESULTS: The ABR threshs were increased in the ciprofloxacin administrated group, and the increased latency of the first waves were identified in the ciprofloxacin administrated group, but there were no differences in the interval of wave I-III. The LM findings of incudomalleolar joint in the ciprofloxacin administrated group showed cartilage lesions such as disrupted articilar surface, irregular cellularity of the chondrocytes, matrix swelling, cleft formation, decreased matrix staining. The TEM findings of the incudomalleolar joint cartilage in the ciprofloxacin administrated group showed decreased bundle-like matrix and cell process, condensed nucleus, and vacuolated cytoplasm. CONCLUSION: From the results of recent works and the present study, we suggest that ciprofloxacin may induce morphological changes in the incudomalleolar joint, and that such morphological changes may induce conductive hearing loss.

BACKGROUND AND OBJECTIVES: Cisplatin is frequently used in the treatment of various forms of malignancies. It's therapeutic efficacy, however, is limited due to the occurrence of sensorineural hearing loss. Little is known about the course of hearing loss after cessation of cisplatin administration. We observed the cochlear duct morphology with normal and cisplatin treated animals. MATERIALS AND METHODS: Healthy rats (strain Sprague-Dawly, weighting 80-100 mg) were used for all experiments. Total 15 rats were selected. They were divided into two groups, a treated group and a control. Four survival groups (n=3, respectively) were assigned as the treated group. After treatment with cisplatin, each survival group was sacrificed 1, 4, 10, 20 days. Except for the normal control (n=3), twelve animals were treated with cisplatin by daily I.P. injection of 1.5 mg/kg for 8 consecutive days. RESULTS: One day after cessation of cisplatin administration, outer hair cells (OHCs) loss and stria vascularis were degenerated especially in the basal turn. At 4, 10, 20 days, the OHCs and stria vascularis morphology of the survival group were similar to those of the survival group at one day. CONCLUSION: Our findings suggest cisplatin ototoxicity is predominantly involved in the basal turn of cochlear duct. This finding was significantly correlated with high frequency hearing loss of cisplatin ototoxicity.

Extramedullary plasmacytomas (EMPs) are rare, low-grade and malignant transforming solitary tumors consisting of neoplastic plasma cell proliferation that occurs in the bones of the head and neck. Ninety percent of solitary EMPs occur in the head and neck region: these constitute, however, less than 1% of all head and neck malignancies. EMPs represent up to 4% of nonepithelial lesions of the upper respiratory tract. On initial presentations, they must be differentiated from multiple myeloma. At first, EMPs are frequently seen as masses or swellings, accompanied by nasal or pharyngeal symptoms. EMPs are of special interest to otolaryngologists, because the majority of these unusual tumors are present in soft tissues of the head and neck. We present the patient with EMPs of tonsil and adenoid and discuss the related literature on the presentation, epidemiology, workup and management of patient with this rare neoplasm.

Cervical cancer is the most common malignancy of the female genital tract in Korea. The most common histologic type of cervical cancer is squamous cell carcinoma. The simultaneous occurrence of histologically distinct squamous cell carcinoma of the cervix and invasive adenocarcinoma of the cervix is extremely unusual. We have experienced two cases of synchronous squamous cell carcinoma and adenocarcinoma of the uterine cervix. We report these cases with a brief review of the literature.

OBJECTIVE: The objectives of this study were twofold: to verify whether the type of metastasis (lymphatic vs. hematogenous) is a prognostic factor, and to identify molecular markers associated with survival in patients with disseminated cervical cancer. METHODS: Between April 1997 and May 2008, 30 patients with disseminated cervical cancer who had supraclavicular lymph node (N=13) or hematogenous metastases (N=17) were initially treated at our institute. We reviewed medical records to extract clinicopathologic variables. For 17 patients with available pathological specimens, we evaluated the association of immunohistochemical staining for metalloproteinase (MMP)-2, vascular endothelial growth factor (VEGF)-A, and laminin V gamma (LAMC)-2 with survival and clinicopathologic variables via a log-rank test and Cox regression analysis. RESULTS: Patients who had only lymphatic metastasis (odds ratio [OR], 5.3; 95% confidence interval [CI], 1.4 to 19.5) or completed initial treatment (OR, 3.2; 95% CI, 1.1 to 9.9) showed better survival than patients who did not, but none of the molecular markers were associated with survival. Out of 13 patients with only lymphatic metastasis, three patients who had received volume-directed radiation with concurrent chemotherapy had a long-term survival of over two years. However, patients with hematogenous metastasis showed extremely poor prognosis. CONCLUSION: The type of metastasis and completion of initial treatment were associated with prolonged survival in patients with disseminated cervical cancer, and over 20% of patients with lymphatic metastasis were salvaged with volume-directed radiation with concurrent chemotherapy. None of the molecular markers were associated with survival in patients with disseminated cervical cancer.

There were few studies about anatomic characteristics in Korean humerus recently. In addition, there was no comparison between Westerner (European and American) and Korean in anatomic characteristics of humerus. The aims of this paper are therefore to investigate anatomic characteristics in Korean humerus and to compare them with those of Westerner humerus. The seventy-two humerus (male : 66, female : 6) were scanned by computed tomography and three dimensional (3D) models of humerus were then reconstructed from acquired cross-section images. The twenty-one anatomic characteristics of the humerus were analyzed and were measured for each humerus. From the results, humeral head vertical diameter in the present study was generally bigger than that in the previous study (p<0.05). There was no significant difference between the anatomic characteristics of the right and left humerus in the present Korean (p>0.05). Humeral head inclination angle, greater tuberosity lateral offset distance, humeral head height in Korean were generally bigger than those in Westerner (p<0.05). This study may contribute to develop an optimal implants and prostheses for the treatment of humerus fractures of Koran.
