Candida albicans is the most common cause of infectious esophagitis and usually is an opportunistic infection in immunocompromised patients. Dysphagia and odynophagia are the usual presenting complaints and, importantly, oral lesions are absent in 50 percent of patients. The role of gastrointestinal endoscopy in diagnosing fungal infections of the esophagus is primary. It is the most definitive and often the only method of detecting esophageal candidiasis. Accurate endoscopic diagnosis by biopsy or brushing leads to the initiation nf effective therapy. We have experienced a case of esophageal candidiasis in an 11-year-old girl who was immunologically normal and whose main symptoms were epigastric abdominal pain and nausea for 4 months. The endoscopic and pathologic findings of esophageal candidiasis were presented.

The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.

Objectives: The purpose of this study was to evaluate the postoperative anteroposterior stability and improvements in facial asymmetry after performing LeFort I osteotomy in the maxilla, sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO) in the mandible, and lateral corticectomy on the IVRO side. Materials and Methods: From July 2009 to October 2018, a retrospective analysis was performed on 11 subjects. Lateral cephalometric radiograph was performed preoperatively (T0), postoperatively (T1), and at 12 months of follow-up (T2), and the B point distance was measured. Posteroanterior cephalometric radiograph was performed preoperatively (S0) and at 12 months of follow-up (S1) and was used to measure five indicators (Ag angle, M-Ag, Co-Ag, Co-Me, and Ag-Me) of facial asymmetry. Results: The B point distances for T0 and T1 were significantly different (P=0.007), whereas those for T1 and T2 were not significantly different (P=0.1). In addition, there was a significant difference between the B point distances of T2 and T0 (P=0.026). Comparison of the facial asymmetry indicators before and after surgery showed a significant difference for all indicators between S0 and S1: the P-values of Ag angle, M-Ag, Co-Ag, Co-Me, and Ag-Me were 0.003, 0.003, 0.008, 0.006, and 0.004, respectively. The Z value was based on negative ranks. Conclusion There was no significant difference in the B point distances from postoperation to the 12-month follow-up. However, there were significant differences in all five indicators related to facial asymmetry before and after surgery. The values for the five indicators of facial asymmetry all increased postoperatively.

CDH-13(T-cadherin), which is one of a kind among the 20 cadherins, can be found mainly in wall of aorta, neuron, spleen, blood vessel etc. It is also called H-cadherin. This structural difference can explain that CDH-13 is thought to play a key role in maintaining mutual relation between extra and intra-cellular environment rather than in cell adhesion. The main function of CDH-13 is to participate in blood vessel function. Additionally, it is known to regulate cell growth and cell contact inhibition. When cells are proliferating, cell surface perceives other cells so that substance such as CDH-13 can inhibit their growth or proliferation resulting in homeostasis without endless proliferation or invasion of connective tissue boundaries. However, tumor cell itself appears to be different from normal cells' growth, invasion or transmission. Therefore, it can be diagnosed that these characteristics are closely related to expression of CDH-13 in tumor cells. This study is to investigate expression of CDH-13 in SCC and its correlation with promoter methylation. 20 of tissue species for the study are excised and gathered from 20 patients who are diagnosed as SCC in department of OMS, dental hospital, dankook university. To find development of CDH-13 in each tissue samples, immunohistochemical staining, RT-PCR gene analysis and methylation specific PCR are processed. The results are as follows. 1.Immunohistochemical staining: In normal oral squamous epithelial tissue, strong expression of CDH-13 was found in cell plasma membrane of basal cell layer. On the other hand, in case of low-differentiated oral SCC, development of CDH-13 was hardly seen. 2.The development of CDH-13 gene: In 9 of samples, expression of CDH-13 gene could be seen and 2 of them showed low expression compared to the others. And rest of the 11 samples showed no expression of CDH-13 gene. 3.Methylation of CDH-13 gene: Among 9 samples which expressed CDH-13 gene, 7 of them showed unmethylation. In addition, among 11 samples without CDH-13 gene expression, 10 showed methylation. According to the results stated above, promoter methylation were found in 13 samples(65%) among 20 of oral SCC samples. In low-differentiated SCC, suppression of gene expression could be seen accompanying promoter methylation. These phenomenon of gene expression was proved by immunohistochemical investigation. Finally, for development of oral SCC, conclusions can be made that suppression of CDH-13 played a main role and suppression of gene expression was originated from promoter methylation. Considering this, it is expected that suppression of CDH-13 from promoter methylation to be utilized as a good diagnostic marker of oral SCC.

Verrucous carcinoma is simply very well differentiated malignant neoplasm. It is unique only in that the diagnosis is difficult to make histologically and locally invasive but metastasis is rare. Clinically, verrucous carcinoma is often warty and usually exophytic. It can be multicentric. It looks uniquely epithelial. When biopsy is done, the pathologist uses words such as "hyperplasia", "keratosis" or "fibrosis", however is reluctant to use the word "carcinoma". Verrrucous carcinoma can be present in three forms: oral or mucosal, genital, and plantar. Base of tongue is uncommon site in it. Authors are reporting a case of huge verrucous carcinoma of base of tongue with a view of the related articles.

OBJECTIVE: The purposes of this study were to identify the incidence of subcortical aphasia and to investigate the different linguistic characteristics and prognosis. METHOD: Twenty-nine stroke patients(18 men and 11 women) with aphasia were investigated in the study. On the basis of the findings of brain CT and MRI images, the patients were divided into either cortical aphasia group or subcortical aphasia group. Fifteen cortical aphasia patients and 14 subcortical aphasia patients underwent an aphasia screening test. Fluency, comprehension, speech, naming, repetition, reading, and writing abilities were evaluated as the modalities of language. All patients received the speech therapy and were reevaluated at three months after the initial evaluation. RESULTS: The incidence of subcortical aphasia was 48.3% of all aphasia patients from the stroke. Subcortical aphasia patients showed more variable types of aphasia and less linguistic damage than the cortical aphasia patients. The prognosis of subcortical aphasia patients was better than the cortical aphasia patients. Especially the cases of global aphasia from the subcortical lesions showed a rapid recovery and good prognosis. CONCLUSION: Early recognition of the subcortical aphasia and a comprehensive speech therapy would be beneficial for the improvement of linguistic function in the subcortical aphasia patients.
