Descending necrotizing mediastinitis(DNM) can occur as a complication of oropharyngeal and cervical infections that spread to the mediastinum via the cervical spaces. Delayed diagnosis and inadequate mediastinal drainage through a cervical or minor thoracic approach are the primary causes of a high mortality rate. Therefore, We emphasize that aggressive and emergent mediastinal drainage by surgical approach is most important method of DNM treatment. We studied 5cases diagnosed as DNM from 2005 through 2007. All patients underwent emergent surgical drainage of deep neck infection combined with mediastinal drainage through a thoracic approach. Primary oropharyngeal infection lead to DNM in four cases(80%) and odontogenic abscess in one case(20%). The outcomes were favorable 5patients. Overall mortality rate was 0%. The time interval from diagnosis based on manifestation of initial symptoms(oral or pharyngolaryngeal area) to surgical intervention was $7.4{\pm}4.2$days. One patient required reoperation due to remnant mediastinal abscess and pericardial effusion. Early diagnosis and emergent combined drainage with neck and chest incisions, together with broad spectrum intravenous antibiotics, should be considered standard care for this disease. And intensive postoperative care which it is continuous mediastinal irrigation and antibiotics use can significantly reduce the mortality rate.

Background and Objectives: Squamous cell carcinoma of retromolar tringone (RMT) is an uncommon head and neck tumor. RMT cancer has unique clinical feature and specific considerations for surgical treatment are needed but, reports on the treatment of RMT cancer are still lacking. Patients and Methods: From May 1997 to July 2004, 8 patients with histologically proven squamous cell carcinoma of the RMT were treated in Severance Hospital. Surgical excision of the primary lesion and neck dissection were performed in all patients. Reconstruction was accomplishing using several methods. Charts and other medical records were reviewed. Results: In early cases, lower cheek flap was appropriate but, mandibular swing or madibulectomy approach was appropriate in advanced cases. Reconstruction was needed in all patients and excision of mandible was needed in majority of patients. 6 patients were disease free status and one died from recurrence and one was lost to follow up. Conclusion: In treatment of RMT cancer, several surgical approach methods and reconstruction should be considered before treatment. Surgical treatment of RMT cancer may be one of a useful primary treatment modality.

Total of 7,495 children including 3,908 boys and 3,587 girls from a kindergarten and 15 primary schools were examined for head lice infestation (HLI). The overall prevalence of HLI in this study was found to be 5.8%. Head lice were much more commonly detected in girls than in boys with prevalence of 11.2% and 0.9%, respectively. Sixty-nine children with HLI were treated with 1% lindane shampoo alone (group 1), and 45 children with HLI were treated with 1% lindane shampoo and oral trimethoprim/sulfamethoxazole (group 2), and follow-up visits were conducted 2 and 4 weeks later, The children who still had HLI 2 weeks after the primary treatment were treated again. At the 2-week follow-up visit, the treatment success rates of groups I and 2 were 76.8% and 80.7%, respectively, and at the 4-week follow-up visit, the rates were 91.3% and 97.8%, respectively. No statistically significant synergistic effect was observed for the combination of a 1% lindane shampoo and oral trimethoprim/sulfamethoxazole.

강원도내 국민학생들에게서 머릿니 감염상황을 알아보기 위하여 1990년 12월 도내 4개 국민학교에서 성충이나 서캐 감염 여부를 조사하였다. 912명의 대상 학생들 가운데 37.2%가 성충이나 서캐에 감염되어 있었다. 270명에서는 성충 및 서캐 감염을 구분하여 조사하였는데, 서캐만 발견된 경우가 36.3%, 성충만 발견된 경우 1.5%, 둘다 보인 경우가 21.9%로 머릿니 성충 감염율은 23.3% 이었다. 어떠한 구제법도 시행하지 알고 6개월 뒤 재조사한 한 학교에서 감염율이 처음 66.0% 에서 57.3%로 나타나 유의한 차이가 얼었다. 이러한 현상은 고도 감염집단에서 짧은 기간 동안 화학요법 시행 없이 자연적인 감염율의 감소를 기대하기 어려움을 잘 보여준다. 머릿니 감염의 역학에서 충체 양성율이 한 집단에서 직접적인 전파력을 표현하는 지수로 중요하다고 판단한다.

Small cell carcinoma mainly occurs in the lung. Approximately 2.5-5% of small cell carcinomas are primary extrapulmonary which are commonly found in the esophagus, GI tract, skin, uterus, and urinary tract. Small cell carcinoma of the head and neck is extremely rare and its prognosis is poor. We report a case of supraglottic small cell carcinoma with cervical lymph node and rib metastasis in a 75-year-old man. The patient was treated with sequential combination of chemotherapy and radiotherapy, but the cancer has progressed. We concluded that we have to find an effective therapy for laryngeal small cell carcinoma.

Objectives: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide. Inconsistency in various histopathologic features for predicting nodal metastasis and overall prognosis and a better understanding of molecular mechanisms of tumourigenesis have shifted the focus to a search for more definitive predictive markers. To identify the role of two immunohistochemical (IHC) markers, E-cadherin and cyclin D1, as predictive markers of aggressiveness in HNSCC and to assess clonal expansion of tumour cells. Materials and Methods: A total of 66 cases of HNSCC with neck node dissection were studied. IHC was performed on primary tumour sections and lymph nodes showing metastatic deposits. Histopathological parameters such as tumour grade and TNM stage together with nodal status were compared according to expression of the two markers. Fischer's chi-square test was used to assess the correlation between the two markers and histopathological parameters. Results: Out of 66 cases studied, 37 showed LN metastasis. Most of the patients were male, and the most common tumour site was buccal mucosa. We found a significant association between loss of E-cadherin and node metastasis (P<0.001) and higher TNM stage (P<0.001). Cyclin D1 overexpression was significantly associated with only nodal metastasis (P=0.007). No significant association with tumour grade was found for either marker. The subgroup of E-cadherin loss with cyclin D1 overexpression was associated with the maximum incidence of nodal metastasis and higher TNM stage, highlighting the importance of using a combination of these two markers. A significant association was noted between the expression of markers at the primary site and at nodal deposits, indicating clonal expansion. Conclusion: A combination of the two markers E-cadherin and cyclin D1 can predict prognosis in HNSCC, although tumour heterogeneity may affect this association in some cases.

목적 : 두경부종양에서 근치적 목적의 방사선치료를 시행하는 경우 종양의 방사선 반응도를 예측하는 것은 방사선치료 계획을 세우는 데 있어서 매우 중요하다. 따라서 본 저자들은 방사선치료 46 Gy 시점과 종료 시점에서 FDG-PET을 시행하여 방사선치료 반응성을 예측할 수 있는지 알아보고자 하였다. 대상 및 방법 : 2002년 10월부터 2003년 5월까지 서울아산병원 방사선종양학과에서 두경부종양으로 진단 받고 근치적 목적의 방사선치료를 시행 받은 22명에 대한 전향적 분석을 시행하였다. 본 연구계획서는 본원 임상윤리위원회를 통과하였고, 자발적으로 참여한 환자들에서 서면으로 동의를 받고 연구대상에 포함하였다. 모든 환자는 1차 FDG-PET을 방사선치료 시작 4주 이내에 시행하고 방사선치료 45 Gy 시점에서 제 2차 FDG-PET을 촬영하였고, 처음 계획된 선량이 모두 조사되는 시점에서 제 3차 FDG-PET을 시행하였다. 모든 환자는 최소한 방사선치료 종료 후 3개월 이상 추적하여 방사선치료 반응을 평가하였다. 로즈노 연구대상에 포함된 환자 중에서 남자는 19명이었고 여자는 3명이었다 이들의 연령은 25세에서 70세까지 분포하였고, 중앙연령은 56세였다. 종양의 발생 부위에 따라 나누어 보면 비인강암이 13명이었고, 후두암이 6명이었고, 설암, 하인두암, 접형동암이 각각 1예였다. 방사선치료 46 Gy 시점에서 FDG- PET의 섭취가 변화 없는 경우는 1예였고 방사선치료 종료 시점에서 FDG-PET상 완전반응을 보인 경우는 20예였고 1예는 부분반응을 보였다. FDG-PET상 완전반응을 보인 20예 중에서 2예는 국소재발하였고 1예는 국소재발과 경부림프절에 동시에 재발하여 현재까지 3명이 재발하였다 결론 : 방사선치료 46 Gy 시점에서 FDG-PET의 FDG섭취 감소가 현저한 경우는 방사선에 반응을 보이는 것으로 생각되었고 FDG 섭취의 변화가 전혀 없거나 방사선치료 종료 시점에서 FDG-PET 촬영상 완전반응을 보이지 않는 경우 잔존종양의 가능성이 매우 높다고 생각되었다.

Background: The optimal sequence and extent of multimodality therapy remains to be defined for extrapulmonary small cell carcinoma because of its rarity. The purpose of our study was to assess the response to neoadjuvant chemotherapy followed by chemoradiation/radiation in patients with extrapulmonary small cell carcinoma. Materials and Methods: Four consecutively diagnosed patients were included in this study. The primary tumor site was oropharynx in three patients and esophagus in one. The patients with the limited disease were treated with chemotherapy followed by concurrent chemoradiation (n=2) or radiotherapy (n=1). The patient with the extensive disease with the primary site in vallecula was treated with chemotherapy and palliative radiotherapy to the metastatic site. Results: The median follow-up was 22.5 months (range, 8-24 months). Three patients with the limited disease (base of tongue, n=2; esophagus, n=1) were in complete remission. The patient with the extensive disease died of loco-regional tumor progression at 8 months from the time of diagnosis. Conclusions: The combination of chemotherapy and radiotherapy is the preferred therapeutic approach for patients with extrapulmonary small cell carcinoma. Induction chemotherapy followed by concurrent chemoradiation or radiation provides a good loco-regional control in patients with limited disease.
