Background/Aims:
Adenoid cystic carcinoma (ACC) is a rare salivary gland tumor characterized by indolence, with a high rate of local recurrence and distant metastasis. This study aimed to investigate the effect of concurrent chemoradiation (CCRT) on locally advanced unresectable ACC.
Methods:
We retrospectively analyzed clinical data from 10 patients with pathologically confirmed ACC of the head and neck who received CCRT with cisplatin in Seoul National University Hospital between 2013 and 2018.
Results:
Ten patients with unresectable disease at the time of diagnosis or with positive margins after surgical resection received CCRT with weekly cisplatin. Eight patients (80%) achieved complete remission, of which three later developed distant metastases without local relapse; one patient developed distant metastasis and local relapse. Two patient achieved partial remission without progression. Patients experienced several toxicities, including dry mouth, radiation dermatitis, nausea, and salivary gland inflammation of mostly grade 1 to 2. Only one patient showed grade 3 oral mucositis. Median relapse-free survival was 34.5 months (95% confidence interval, 22.8 months to not reached).
Conclusions
CCRT with cisplatin is effective for local control of ACC with manageable toxicity and may be an effective treatment option for locally advanced unresectable ACC.

Purpose:
This study was aim to evaluate the patterns of failure according to radiotherapy (RT) target volume for cervical lymph nodes in metastases of unknown primary origin in head and neck region (HNMUO).
Materials and Methods:
Sixty-two patients with HNMUO between 1998 and 2016 were retrospectively reviewed. We analyzed the clinical outcomes and primary site failure depending on the radiation target volume. The target volume was classified according to whether the potential head and neck mucosal sites were included and whether the neck node was treated involved side only or bilaterally.
Results:
Potential mucosal site RT (mucosal RT) was done to 23 patients and 39 patients did not receive mucosal RT. Mucosal RT showed no significant effect on overall survival (OS) and locoregional recurrence (LRR). The location of primary site failure encountered during follow-up period was found to be unpredictable and 75% of patients with recurrence received successful salvage therapies. No significant differences in OS and LRR were found between patients treated to unilateral (n = 35) and bilateral neck irradiation (n = 21). Treatment of both necks resulted in significantly higher mucositis.
Conclusions
We found no advantages in OS and LRR of patients with HNMUO when mucosal sites and bilateral neck node were included in the radiation target volume.

BACKGROUND/AIMS:
Since patients with human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) have favorable outcomes after treatment, treatment de-escalation for these patients is being actively investigated. However, not all HPV-positive HNSCCs are curable, and some patients have a poor prognosis. The purpose of this study was to identify poor prognostic factors in patients with HPV-positive HNSCC.
METHODS:
Patients who received a diagnosis of HNSCC and tested positive for HPV from 2000 to 2015 at a single hospital site (n = 152) were included in this retrospective analysis. HPV typing was conducted using the HPV DNA chip assay or liquid bead microarray system. Expression of p16 in the tumors was assessed by immunohistochemistry. To determine candidate factors associated with overall survival (OS), univariate and multivariable Cox regression analyses were performed.
RESULTS:
A total of 152 patients with HPV-positive HNSCC were included in this study; 82.2% were male, 43.4% were current or former smokers, and 84.2% had oropharyngeal cancer. By univariate analysis, old age, performance status ≥ 1, non-oropharyngeal location, advanced T classification (T3–4), and HPV genotype 18 were significantly associated with poor OS. By multivariable analysis, performance status ≥ 1 and non-oropharyngeal location were independently associated with shorter OS (hazard ratio [HR], 4.36, p = 0.015; HR, 11.83, p = 0.002, respectively). Furthermore, HPV genotype 18 positivity was also an independent poor prognostic factor of OS (HR, 10.87, p < 0.001).
CONCLUSIONS
Non-oropharyngeal cancer, poor performance status, and HPV genotype 18 were independent poor prognostic factors in patients with HPV-positive HNSCC. Patients with these risk factors might not be candidates for de-escalation treatment.

BACKGROUND: Complementary and alternative medicine (CAM) use is popular and current trend suggests a demand for CAM education during residency training. Our objective was to assess perception, the need and experience of CAM education for family practice residents by training faculty. METHODS: A questionnaire was administered to family physicians (n=262) who were registered in the Korean Academy of Family Medicine as residency training faculty between February and May 2006. RESULTS: One hundred and seven (40.8%) of 262 faculty completed the questionnaires. Eighty three (77.6%) respondents recognized the need of CAM education during residency training and fifty two (46.8%) respondents have already educated some kind of CAM. Thirty nine (36.4%) respondents replied that partial CAM educational contents were given out at conferences. Seventy eight (72.9%) respondents recognized the need for educating residents on the general outlines of CAM along with education on verified CAM. Sixty six (61.7%) respondents replied that the Korean Academy of Family Medicine should host such education. CONCLUSION: Most family practice training faculty recognized the need for providing CAM education for family practice residents during residency training, but about an half of family practice training faculty did not have experiences of CAM education.

Von Meyenburg complexes (VMC) have many synonyms such as bile duct hamartomas and biliary hamartoma. These rare benign disorders are considered as congenital diseases caused by malformed differentiation of ductal plate. The diagnosis of VMC by common radiologic modality such as ultrasound and computed tomography was nearly impossible until the emergence of cholangiopancreatography by magnetic resonance imaging (MRCP) and the pathologic examination was the only way to confirm the diagnosis of VMC. But MRCP is now considered as most accurate noninvasive method for diagnosis of VMC. We report a histologically proven case of VMC associated with calculous cholecystitis, cerebral aneurysm and renal cortical cyst. To our knowledge, no comparable case has been reported and this would be the only second reported case of VMC, which was diagnosed by MRCP.

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) has been reported in a great variety of diseases and disorders of central nervous system (CNS). However, there has been only 7 cases of SLE reports in association with SIADH and correlation of SIADH and SLE has not been clearly demonstrated. Previous cases showed improvement of SIADH as lupus activity resolved during treatment. We report a case of SLE in association with SIADH which showed improvement during treatment with prednisolone and cyclophosphamide.

Lipomas are among the most common of all benign neoplasma and occur more frequently over the back, between the shoulders, and on the back of the neck. They are usually subcutaneous in origin, and characteristically multilobulated masses of fatty tissue that vary from small nodules to large masses weighing several kilograms.A mass in the anterior part of the neck may be initially thought to be thyroid nodules and then other cervical masses should be considered. Ultrasonographic examination of benign lipoma demonstrates solid and echogenic mass and may differentiate nonthyroid from thyroid masses. When lipoma is clinically suspected, the use of CTs can establish the correct diagnosis without the use of thyroid hormone suppression or the need for urgent surgery.We experienced a case of anterior cervical mass in a 51-year-old male patient presenting a non-tender and soft mass rapidly growing for recent several months and moved with swollowing, and diagnosed his case as benign lipoma using ultrasonography, computed tomographic scan, and fine niddle asperation biopsy and therefore when we encounter patients with anterior neck mass, we should consider benign lipoma mimicking thyroid nodule.

Cystic dilatation of bile duct, so called choledochal cysts are a well documented abnormalities. Although choledochal cyst is a relatively rare disease, the number of reports have been increasing especially in tht Orient. It may be easily overlooked by the conventional diagnostic methods, such as upper gastrointestinal series, intravenous cholangiography and abdominal ultrasonogrsphy. Recent advances on diagnostic methods, such as endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography had been helpful in demonstrating choledochal cysts. 29 patients with choledochal cysts who had been admitted in Hanyang Universty Hospital between September l981 and August 1991 were reviewed and the clinical endoseopic and rediographic findings were discussed comparing with that from foreign literatures.

Henoch-Schonlein purpura(anaphylactoid purpura) is a necrotizing vasculitis of small vessels in which systemic manifestation include palpable purpura on the lower extremities and buttocks due to leukocytoclastic vasculitis of dermal vessels; arthralgia of large joints, usually the knees and ankles; gastronitestinal involvement with colic and bleeding; and renal ievolvement, usually with a focal necrotizing glomerulonephritis. Gastrointestinal involvement occurs in about two thirds of all pediatric cases and in about,one third of adult cases, Any bowel segment may be involved, but the jejunum and ileum are most frequently affected. With a brief review of the literature, we report a case of H-S purpura involving stomach and duodenum.
