The presence of HPV DNA and the expression of p53 protein and proliferating cell nuclear antigen(PCNA) in head and neck squamous cell carcinoma were determined to evaluate the relationship of these factors and their association with their pathologic stages and cervical lymph node metastasis. Among 65 patients the presence of HPV DNA was found in 12 cases(18.5%), p53 was found positive in 32 cases(49.2%) and expression of PCNA was observed in 24 cases(36.9%). The expression of PCNA was more frequent in the HPV positive cancers compared with the HPV negative ones(p =0.0018), and p53 revealed its higher rate of cooccurrence with the expression of PCNA(p =0.008), which might suggest that PCNA expression has a positive relationship with HPV and p53 mutation in head and neck cancer. There might be inverse relationship between HPV and p53 mutation(p =0.063), but 3 cases showed both HPV DNA positivity and p53 expression. HPV was detected at a higher rate in the early pathologic stages than in the advanced stages of cancer, and p53 expression was more frequently found in the advanced stages(p =0.044). These results suggests that HPV and p53 mutation might have different etiologic roles in the development of head and neck cancer, or cases with p53 mutation might have more aggressive behavior. PCNA expression showed no difference between early and late stages of cancer, and between cases with and without cervical lymph node metastasis.

The purposes of this study were to evaluate the presence or absence of pain with the jerk test as a predictor of the success of nonoperative treatment for posteroinferior instability of the shoulder and to identify pathologic lesion responsible for the pain in the jerk test. Eighty-nine shoulders(81 patients), which had posteroinferior instability with positive posterior clunk in the jerk test, were nonoperatively treated. The patients were divided into two groups with respect to the presence of pain in the jerk test: painless jerk group(54 shoulders) and painful jerk group(35 shoulders). Response to the nonoperative treatment was evaluated after at least 6 months rehabilitation program. Patients who did not respond to the rehabilitation underwent arthroscopic examination to identify any pathologic lesion. The painful jerk group had higher failure rate with nonoperative treatment (p<0.001). In the painless jerk group, fifty shoulders (93%) responded to rehabilitation program after a mean of 4 months. Four shoulders(7%) were unresponsive to the rehabilitation. In the painful jerk group, five shoulders(16%) were successful with the rehabilitation while the other thirty shoulders(84%) failed. All 34 shoulders, which were unresponsive to the rehabilitation, had a variable degree of posteroinferior labral lesions. In conclusion, the jerk test is a hallmark for predicting the prognosis of nonoperative treatment in the posteroinferior instability. Shoulders with symptomatic posteroinferior instability and a painful jerk test have posteroinferior labral lesion.

Purpose: Trichoblastic fibroma originates from hair germ layer tumor which is a benign tumor mixture of epidermal and mesodermal factor. Trichoblastic fibroma was found only in adults and showed equal occurrence rate between men and women. Since it is a rare tumor, we report a case of a trichoblastic fibroma which developed on the right cheek. Methods: A 72 year-old male was treated with excisional operation 17 years ago due to a solitary tumor that developed on the same site. He returned to the hospital with an asymptomatic mass which have been increasing in size for the last 3 months. Results: In computerized tomography, a size of $2.7{\times}2.3{\times}0.8cm$ tumor was found in the subcutaneous tissue layer. Grossly, the mass was well-circumscribed, smooth-surfaced and flesh colored, and was lobulated and fragile. Pathologic observation showed diverse shaped and sized tumor cell nests and fibrocellular stroma consisting basophilic cells in dermal and subdermal layers. Immunohistopathologic staining showed positive reaction on pancytokeratin, CK-5/6, and bcl-2. Conclusion: By having no connection to the epidermis, and being positioned in the dermal and epidermal layers, typical pathologic findings make it possible to differentiate this tumor with basal cell carcinoma. This lesion is not clear whether it is a local recurrence or not, and it is necessary to observe a new recurrence in the future.

Background: Approximately 100,000 women are diagnosed with cancer each year in Korea. According to a survey by the Korean central cancer registry in 2016, uterine cervical cancer, uterine corpus cancer, and ovarian cancer were the 5th, 7th, and 8th most prevalent cancers respectively among Korean women. The present study aims to review the clinico-pathologic characteristics of patients who were treated for major gynecological malignancies at Yeungnam University Medical Center. Methods: Patients with invasive gynecological cancers from January 2012 to February 2019 were retrospectively identified. We analyzed the clinical features, demographic profiles, pathologic data, treatment modality used, adjuvant treatment used, complications, recurrence, and survival outcomes. Results: A total of 287 patients (cervical cancer 115; corporal cancer 86; and ovarian, tubal, or primary peritoneal cancer 90) were included. Most cervical (82.7%) and corporal cancers (89.5%) were diagnosed in the early stages (stage I or II), while more than half (58.9%) the cases of ovarian, tubal or peritoneal cancers were diagnosed in the advanced stages (stage III or IV). Surgical complications were observed in 12.2% of cervical cancers, 16.3% of uterine corpus cancers, and 11.1% of ovarian, tubal, and peritoneal cancers, respectively. The 5-year overall survival rate was 94.1%, 91.0%, and 77.1% for cervical, corporal, and ovarian, tubal, or peritoneal cancers, respectively. Conclusion: Surgical treatment was satisfactory in terms of the incidence of complications, and survival outcomes were generally good. Clinicians should be aware of the clinical and histopathological characteristics of patients with gynecological cancers to be able to provide optimal strategies and counseling.

Background: This study was designed to compare radioguided versus routine wire localization of nonpalpable non-malignant breast lesions in terms of efficacy for complete excision, ease of use, time saving, and cosmetic outcome. Materials and Methods: Patients with non-palpable breast masses and non-malignant core biopsy results who were candidates for complete surgical lumpectomy were enrolled and randomly assigned to radioguided or wire localization groups. Radiologic, surgical, and pathologic data were collected and analyzed to determine the difficulty and duration of each procedure, ease of use, accuracy, and cosmetic outcomes. Results: This prospective randomized study included 60 patients, randomly divided into wire guided localization (WGL) or radioguided occult lesion localization (ROLL) groups. The mean duration of localization under ultrasound guidance was shorter in the ROLL group (14.4 min) than in the WGL group (16.5 min) (p<0.001). The ROLL method was significantly easier for radiologists (p=0.0001). The mean duration of the surgical procedure was 22.6 min (${\pm}10.3min$) for ROLL and 23.6 min (${\pm}9.6min$) for WGL (p=0.6), a non-significant difference. Radiography of the surgical specimens showed 100% lesion excision with clear margins, as proved by pathologic examination, with both techniques. The surgical specimens were slightly heavier in the ROLL group, but the difference was not significant (p=0.06). Conclusions: The ROLL technique provides effective, fast, and simple localization and excision of non-palpable non-malignant breast lesions.

Objectives: The aim of this investigation was to evaluate the efficacy of KHchunggan-tang aqueous extract on the experimental nonalcoholic fatty liver disease(NAFLD) induced by palmitate. Materials and Methods: To generate a cellular model of NAFLD, we used HepG2 cells, a human hepatoma cell line, treated with 0.5 mM palmitate. By this cellular model, effects of KHchunggan-tang aqueous extract were evaluated. Intracellular lipid accumulation, free radical formation, and apoptosis were detected by Nile red staining, 2',7'-dichloroflourescin diacetate(H2DCF-DA), and 4',6-diamidino-2-phenylindole(DAPI)/propidium iodide(PI) staining, respectively. Some proteins related with NAFLD were determined by western blot. Results: Typical pathological features of NAFLD occurred in the cellular model. Palmitate increased the levels of intracellular lipid vacuoles, decreased cell viability, and increased apoptosis. Palmitate increased free radical formation and lipid peroxidation, too. However, KHchunggan-tang aqueous extract reduced palmitate-induced pathologic features, i.e. steatosis, free radical formation, and apoptosis. In addition, KHchunggan-tang aqueous extract suppressed palmitate-activated c-Jun N-terminal kinase(JNK) signaling, and SP600125, a JNK inhibitor, significantly reversed the palmitate-induced pathologic changes as KHchunggan-tang aqueous extract. It means that the signaling pathway other than JNK can be involved in the KHchunggan-tang mediated cellular protection of palmitate-treated Hep G2 cells. Conclusions: These results suggest that KHchunggan-tang aqueous extract has hepatoprotective effects on NAFLD with combined properties in cellular steatosis, ROS production, and cytoprotection, and thus may have valuable clinical applications for treatment of this chronic liver disease.

The researches for tumor and the developments for new anti-tumor medicine are being continuously developed in the oriental as well as the west. The principles therapy of anti-tumor activity was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils. But the major clinical features of tumor was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distinction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. In clinical study and experimental study, the effects of oriental medicine could be summarized as three that were decreasing toxicity of chemo-therapy, directly suppressing and killing cancerous cell and increasing chemo-effect through preventing metastasis. Improving organic immunity with oriental medicine could be summarized as five that were promoting phagocytosis of macrophage, inducing interferon, promoting formation of immnoglobulin, increasing number of T-cell and promoting transformation of lymphocyte. It is suggested that effective use of immune activating herbs inhibited metastasis and decreased recurrence and then we were able to expect increasing survival rate and improving clinical symptoms and quality of life(QOL) of tumor patients.

Objective : To analyze the incidence and characteristics of delayed postoperative fever in posterior cervical fusion using cervical pedicle screws (CPS). Methods : This study analyzed 119 patients who underwent posterior cervical fusion surgery using CPS. Delayed fever was defined as no fever for the first 3 postoperative days, followed by an ear temperature ≥38℃ on postoperative day 4 and subsequent days. Patient age, sex, diagnosis, laminectomy, surgical level, revision status, body mass index, underlying medical disease, surgical duration, and transfusion status were retrospectively reviewed. Results : Of 119 patients, seven were excluded due to surgical site infection, spondylitis, pneumonia, or surgical level that included the thoracic spine. Of the 112 included patients, 28 (25%) were febrile and 84 (75%) were afebrile. Multivariate logistic regression analysis showed that laminectomy was a statistically significant risk factor for postoperative non-pathological fever (odds ratio, 10.251; p=0.000). In contrast, trauma or tumor surgery and underlying medical disease were not significant risk factors for fever. Conclusion : Patients who develop delayed fever 4 days after posterior cervical fusion surgery using CPS are more likely to have non-pathologic fever than surgical site infection. Laminectomy is a significant risk factor for non-pathologic fever.

Introduction: The characteristics of oral tongue squamous cell carcinomas (SCC) and the treatment results were reviewed to determine the appropriate treatment strategies. Materials and Methods: The medical records of 140 patients diagnosed and treated for oral tongue SCC at Yonsei University Health System from January 1995 to December 2004 were reviewed. For statistic analysis, the survival rate was determined using the Kaplan-Meier method with SPSS version 12.0, and the difference in survival rates was evaluated using a log-rank test. Results: The mean age of the patients with oral tongue SCC patients was 55 (19-85 years old). According to the T, N and pathologic stage, the patients were distributed from a higher to a lower incidence of cases, as follows: T2 (46.4%), T1 (37.9%), T4 (8.5%), and T3 (7.1%); N0 (65%), N1 (20.7%), N2 (13.6%), and N3 (0.7%); and stage I (31.4%), stage II(25.7%), stage IV (22.2%), and stage III (20.7%). Local and regional recurrence and distant metastasis was present in 13.6%, 5% and 4.2% of patients, respectively. The five-year survival rate was 72.2%, and the prognostic factors for oral tongue SCC included neck metastasis, pathologic stage of the disease, cell differentiation, treatment modality, neck dissection as part of the treatment plan, and neck node recurrence. Discussion: It is suggested that ipsilateral neck dissection or bilateral neck dissection should be selected as a treatment of tongue SCC patients with advanced stage.
