BACKGROUND/OBJECTIVES: Despite multiple approaches of treatments for salivary duct carcinoma, there has been a need for more successful treatment methods because of its poor prognosis. Treatment options like immunotherapy using new technologies have been attempted. Based on recent study results indicating that targeting programmed death receptors are effective in treating various cancers, this study aimed to identify the frequency of PD-L1 expression and its impact on survival rate in salivary duct carcinoma.MATERIALS #SPCHAR_X0026; METHODS: We studied 33 patients with salivary gland cancer who were available for histologic specimens. We examined the expression of PD-L1 in the tissues and analyzed the association with the survival rate and the association with various clinical parameters.RESULTS: According to this study and review of similar studies, we discovered that the expression of PD-L1 in salivary duct carcinoma was lower than other types of cancers. The impact of PD-L1 on survival rate also showed inconsistency in salivary duct carcinoma.CONCLUSION: Immunotherapy by PD-1/PD-L1 checkpoint blockade in salivary duct carcinoma needs further evaluation for clinical application.

An esophagobronchial fistula is a life threatening complication of esophageal carcinoma. Although placement of esophageal stents is the preferred treatment for esophagobronchical fistula, experience of stenting at the proximal esophagus is limited due to technical difficulties, patients' discomfort and high risk of complications. We report here a patient with an esophagobronchial fistula at the proximal esophagus who was successfully treated by insertion of a self expandable metal stent and earlobe fixation by a connective tube for preventing stent migration. A 46-year-old man had an inoperable esophageal carcinoma and lung abscess due to esophagobronchial fistula. Our first placement of stent at the proximal esophagus failed because of foreign-body sensations and stent migration to the proximal region. For the second time, treatment adding an earlobe fixation tool for anti-migration to the esophageal stent was successful with no serious procedure-related complications. The stent completely sealed off the fistula in the patient without further aspiration and serious discomfort symptoms. Lung abscess and pneumonia gradually improved. Anti-migration esophageal stents can be effective in preventing stent migration for the treatment of proximal esophagobronchial fistula due to malignancy.

PURPOSE: Normal gallbladder mucosa shows unique and diverse patterns of mucin genes, and altered mucin expressions have been noted in the gallbladders with stones, dysplasia or carcinomas. The aim of this study was to characterize the expressions of MUC gene proteins in cholecystitis, adenoma and adenocarcinoma of the gallbladder. Differences of MUCs expressions according to the histopathologic parameters in gallbladder carcinomas were also studied. METHODS: Three tissue microarray blocks were made from 23 cases of cholecystitis, 40 cases of gallbladder adenoma, and 66 cases of gallbladder adenocarcinoma. Immunohistochemical stains for MUC1, MUC2, MUC4, MUC5AC and MUC6 were performed, and staining intensity and patterns were evaluated. RESULTS: MUC1, MUC2, MUC4, MUC5AC and MUC6 were overexpressed in 86 (66.7%), 20 (15.5%), 68 (52.7%), 74 (57.4%) and 47 (36.4%) of gallbladder lesions, respectively. MUC1 and MUC2 overexpression rates were higher in gallbladder carcinoma than in cholecystitis and gallbladder adenoma (P<0.05). MUC6 overexpression rate was higher in gallbladder adenoma than in cholecystitis and gallbladder carcinoma (P<0.05). Overexpression of MUC4 and MUC5AC showed no significant differences in cholecystitis, gallbladder adenoma and gallbladder carcinoma. In gallbladder carcinomas MUC1 overexpression rate was high in cases with deeper tumor invasion (P<0.05). MUC6 overexpression rate decreased in cases with larger tumor (P<0.05), higher histologic grade (P=NS), and deeper invasion (P=NS). MUC2, MUC4 and MUC5AC overexpression rates had no relations to the histopathologic parameters. CONCLUSION: Carcinomatous change of gallbladder may be related to MUC1 and MUC2 overexpressions. MUC1 overexpression seems to be related to aggressive biologic behavior of gallbladder carcinoma. MUC6 overexpression acts as a good prognostic factor.

PURPOSE: Tandem mass spectrometry (MS/MS) is effective screening test for inherited metabolic diseases. In this study, we estimate potential costs and benefits of using tandem mass spectrometry (MS/MS) to screen newborns for inherited metabolic diseases (phenylketonuria, BH4 deficiency, citrullinemia, maple syrup urine disease, propionic aciduria, isovaleric aciduria, glutaric aciduria type 1, LCHAD deficiency) in Korea. METHODS: From April 2001 to March 2004, 79,179 newborns were screened for amino acid disorders, organic acid disorders, and fatty acid oxidative disorders. Twenty-eight newborns were diagnosed with one of the metabolic disorder and the collective estimated prevalence amounted to 1 in 2,800 with a sensitivity of 97.67%, a specificity of 99.28%, a recall rate of 0.05%, and a positive preditive value of 6.38%. We calculated and compared the total costs in case when neonatal screening on phenylketonuria, BH4 deficiency, citrullinemia, maple syrup urine disease, propionic aciduria, isovaleric aciduria, glutaric aciduria type 1, LCHAD deficiency is implemented, and when not. RESULTS: If the neonatal screening on phenylketonuria, BH4 deficiency, citrullinemia, maple syrup urine disease, propionic aciduria, isovaleric aciduria, glutaric aciduria type 1, LCHAD deficiency is implemented, total benefits far exceed costs at a ratio of 1.40:1. CONCLUSION: Although, this study only concerns the monetary aspects of the neonatal screening, tandem mass spcetrometry for neonatal screening is cost-effective compared with not screening. The study appears to support the introduction of tandem mass spectrometry into a Korea neonatal screening programme for inherited metabolic diseases.

Typhlitis is one of the most ominous complications in immunocompromised patients. Neutropenic enterocolitis or typhlitis is a clinical syndrome characterized by fever, diarrhea and abdominal pain that occurs in neutropenic patients. It has been reported as a complication of childhood leukemia, but is now known to occur in adults with solid malignancies, acquired immunodeficiency syndrome (AIDS) or bone marrow transplantation (BMT). The association of typhlitis and propylthiouracil has not been previously reported. We report a case of a 42-year-old female patient with typhlitis due to propylthiouracil patient with hyperthyroidism.

BACKGROUND AND OBJECTIVES: The role of endolymphatic sac decompression (ELSD) for the treatment of intractable Meniere disease (MD) has been debated. However, considering few treatment options for medically intractable MD with serviceable hearing or intractable bilateral MD, ELSD has shown reasonable treatment results without ablating inner ear function. The aims of this study are to review the role of ELSD in the treatment of MD and clinical course and long-term outcome after ELSD. MATERIALS AND METHODS: The ELSD was performed in 7 patients among 603 definite Meniere disease patients between May 2003 and December 2010. Patient's medical history and clinical courses after surgery were obtained by medical record review and telephone interview. RESULTS: Mean duration of follow up until receiving ELSD was 575 days since initial visit. Six patients showed complete control or substantial control of vertigo, but one patient suffered from sustained vertigo attacks even after ELSD, the vertigo was controlled after intratympanic gentamicin injection (ITGI) at 20 months after ELSD. Another patient had recurrence of vertigo after 30 months, which was successfully controlled by ITGI. The preoperatively mean monthly vertigo was 4.8 and it was significantly decreased to 1.5 after postoperatively 1 year, 0 after postoperatively 2 years (p<0.001). Hearing was preserved in 6 patients during the follow-up period. CONCLUSION: Most patients who were uncontrolled vertigo with 3 to 6 months medication showed significantly reduced vertigo and hearing preservation after ELSD. The ELSD seems to be a beneficial treatment option for intractable MD.

Background:
The purpose of this study is to examine the combined effects of organizational climate (OC) with emotional labor (EL) on turnover intention in Korean firefighters.
Methods:
The data were obtained from the study Firefighters Research: Enhancement of Safety and Health. A total of 4,860 firefighters whose main duty was providing “emergency medical aid” were included. To examine the effects of OC on the relationships between five subscales of EL and turnover intention, four groups were created using various combinations of OC (“good” vs. “bad”) and EL (“normal” vs. “risk”): (1) “good” and “normal” (Group I), (2) “bad” and “normal” (Group II), (3) “good” and “risk” (Group III), and (4) “bad” and “risk” (Group IV). Multivariate logistic regression analyses were performed to estimate the risk of turnover intention for the combinations of OC and EL.
Results:
The results showed turnover intention was significantly higher in the group with “bad” OC (17.7%) than in that with “good” OC (7.6%). Combined effects of OC and EL on turnover intention were found in all five subscales with the exception of Group I for emotional demands and regulation. Groups II, III, and IV were more likely to experience risks of turnover intention than Group I (p for trend <0.001).
Conclusions
A positive and cooperative OC plays a role in decreasing the risk of turnover intention and in attenuating the negative effects of EL on turnover intention in firefighters.
