BACKGROUND: Depression and anxiety are common psychiatric symptoms in patients with epilepsy, exerting a profound negative effect on health-related quality of life. Several issues, however, pertaining to their association with psychosocial, seizure-related and medication factors, remain controversial. In the present study we have investigated the association of depression and anxiety with various demographic and seizure-related variables in patients with newly-diagnosed and chronic epilepsy. METHODS: We investigated 80 patients with epilepsy (46.3% males, mean age 36.1+/-11.4 years, range 18~64; mean disease duration, 13.4+/-12.2 years). Depression and anxiety were assessed in the interictal state with the Beck Depression Inventory, 21-item version (BDI-21) and the state and trait subscales of the State-Trait Anxiety Inventory (STAI-S and STAI-T), respectively. The association of depression and anxiety with various variables was investigated using univariate analyses and multiple linear regression analyses. RESULTS: Duration of epilepsy, the number of side effects and the number of GABAergic anti-epileptic drugs were correlated with depression, together accounting for 25.1% of the variation of the BDI-21. The STAI-S index was significantly associated with occupation status and the number of GABAergic anti-epileptic drugs accounting for 27.4% of the variation of the STAI-S. Finally, the number of side effects was correlated with trait anxiety. CONCLUSIONS: Our study shows that the duration of epilepsy, occupation status, GABAergic anti-epileptic drugs and the number of side effects are risk factors for the development of depression and/or anxiety.

Background: and Purpose: Ventricle enlargement has been implicated in the pathophysiology of Alzheimer’s disease (AD). We studied the relationship between ventricular size and cognitive function in patients with AD. We focused on the effect of the initial ventricle size on the rate of cognitive decline in patients with AD. Methods: A retrospective analysis of probable clinical AD participants with more than 2 magnetic resonance imaging images was performed. To measure ventricle size, we used visual rating scales of (1) Cardiovascular Health Study (CHS) score and (2) conventional linear measurement method. Results: Increased clinical dementia rating (CDR) was correlated with a decreased MiniMental Status Examination (MMSE) score, and increased medial temporal lobe atrophy (MTLA) and global ventricle size (p<0.001, p<0.001, p=0.021, respectively). There was a significant correlation between the change in cognitive function in the group (70%–100%ile) with a large initial ventricle size (p=0.021 for ΔCDR, p=0.01 for ΔMMSE), while the median ventricle size (30%–70%ile) showed correlation with other brain structural changes (MTLA, frontal atrophy [FA], and white matter) (p=0.036 for initial MTLA, p=0.034 for FA). Conclusions In this study, the initial ventricle size may be a potential new imaging biomarker for initial cognitive function and clinical progression in AD. We found a relationship between the initial ventricle size and initial AD-related brain structural biomarkers.

PURPOSE: The tertiary lymphoid structure (TLS) is an important source of tumor-infiltrating lymphocytes (TILs), which have a strong prognostic and predictive value in triple-negative breast cancer (TNBC). A previous study reported that the levels of CXCL13 mRNA expression were associated with TLSs, but measuring the gene expression is challenging in routine practice. Therefore, this study evaluated the MECA79-positive high endothelial venule (HEV) densities and their association with the histopathologically assessed TLSs in biopsy samples. In addition, the relationship of TLSs with the CXCL13 transcript levels and clinical outcomes were examined. MATERIALS AND METHODS: A total of 108 TNBC patients treated with neoadjuvant chemotherapy (NAC) were studied. The amounts of TILs and TLSs were measured histopathologically using hematoxylin and eosin–stained slides. The HEV densities and TIL subpopulations were measured by immunohistochemistry for MECA79, CD3, CD8, and CD20. CXCL13mRNA expression levels using a NanoString assay (NanoString Technologies). RESULTS: The mean number of HEVs in pre-NAC biopsies was 12 (range, 0 to 72). The amounts of TILs and TLSs, HEV density, and CXCL13 expression showed robust correlations with each other. A lower pre-NAC clinical T stage, higher TIL and TLS levels, a higher HEV density, CD20-positive cell density, and CXCL13 expression were significant predictors of a pathologic complete response (pCR). Higher CD8-positive cell density and levels of CXCL13 expression were significantly associated with a better disease-free survival rate. CONCLUSION: MECA79-positive HEV density in pre-NAC biopsies is an objective and quantitative surrogate marker of TLS and might be a valuable tool for predicting pCR of TNBC in routine pathology practice.

PURPOSE: In the presence of interferon, proteasome subunits are replaced by their inducible counterparts to form an immunoproteasome (IP) plays a key role in generation of antigenic peptides presented by MHC class I molecules, leading to elicitation of a T cell‒mediated immune response. Although the roles of IP in other cancers, and inflammatory diseases have been extensively studied, its significance in breast cancer is unclear. MATERIALS AND METHODS: We investigated the expression of LMP7, an IP subunit, and its relationship with immune system components in two breast cancer cohorts. RESULTS: In 668 consecutive breast cancer cohort, 40% of tumors showed high level of LMP7 expression, and tumors with high expression of LMP7 had more tumor-infiltrating lymphocytes (TILs) in each subtype of breast cancer. In another cohort of 681 triple-negative breast cancer patients cohort, the expression of LMP7 in tumor cells was significantly correlated with the amount of TILs and the expression of interferon-associated molecules (MxA [p < 0.001] and PKR [p < 0.001]), endoplasmic reticulum stress-associated molecules (PERK [p=0.012], p-eIF2a [p=0.001], and XBP1 [p < 0.001]), and damage-associated molecular patterns (HMGN1 [p < 0.001] and HMGB1 [p < 0.001]). Patients with higher LMP7 expression had better disease-free survival outcomes than those with no or low expression in the positive lymph node metastasis group (p=0.041). CONCLUSION: Close association between the TIL levels and LMP7 expression in breast cancer indicates that better antigen presentation through greater LMP7 expression might be associated with more TILs.

Lymphedema refers to inflammation that occurs in a part of the body owing to impaired lymphatic transport. Lymphedema arises as a consequence of a malformation or malfunction of the lymphatic system. It commonly occurs on the face, vulva, and penis and can cause superficial lesions known as lymphangiectasia. Common presenting symptoms include pain, pruritus, oozing of lymphatic fluid, sexual dysfunction, and infection. Prolonged lymphedema can lead to fibrosis and epidermal hyperplasia with verrucous hyperkeratosis. In rare cases, the lymphedema may mimic a skin tumor. We report the case of a 69-year-old woman who presented with erythematous oozing papules and hard nodules on the vulva, which mimicked a fibrous tumor.

Purpose: Primary tumor at the carotid bifurcation is uncommon, which includes paraganglioma, schwannoma, and lymphoma. Due to their rarity, characteristics of these tumors and problems related to their surgical treatment have not been well known. We tried to elucidate different clinical characteristics and surgical complications of these tumors. Materials and Methods: We retrospectively reviewed 21 patients with carotid bifurcation tumor from the Vascular Surgery division of a Korean tertiary institution from 1995 to 2018. We investigated patients’ demographics and clinical features, image characteristics, treatment details, and surgical outcomes. Results: During the period from January 1995 to January 2018, we experienced surgical resections of 21 carotid bifurcation tumors which included 16 (76.2%) paragangliomas and 5 (23.8%) schwannomas. The most common clinical feature was a non-tender cervical mass. According to Shamblin classification, paragangliomas were classified into class II in 68.8% and class III in 25.0%. On the preoperative computed tomography images, all the paragangliomas showed characteristic splaying of the carotid bifurcation and hypervascularity of the tumors. On the contrary, all the schwannomas showed hypovascularity and splaying sign in 60%.Surgical complications related to cervical nerve injury developed in 50% and 60% of patients with Shamblin class III paraganglioma and schwannoma, respectively.During the mean follow-up period of 25 months (range, 1 to 163 months), distant metastases developed in 2 (12.5%) of paraganglioma patients. Conclusion Neurologic complications were more common after surgical resection of Shamblin class III paraganglioma and schwannoma. For patients with paraganglioma, postoperative periodic follow-up examination is advised to detect distant metastasis.

Purpose: Open surgical conversion (OSC) is the last treatment option for patients with endovascular aneurysm repair (EVAR) failure. We investigated the underlying causes of EVAR failure requiring OSC and attempted to determine strategies to avoid OSC after EVAR. Methods: We retrospectively reviewed the database of patients who underwent OSC after EVAR from 2005 to 2018 in a single institution. Twenty-six OSCs were performed in 24 patients (median age, 74.5 years; 79.2% of males) who had undergone standard EVAR. We investigated pre-, intra-, and postoperative computed tomography or angiographic images and outcomes of the OSCs. Results: Two main indications for OSC were persistent endoleak (50.0%) and endograft infection (EI) (38.5%). All 13 patients who underwent OSC due to endoleaks received EVAR outside of indications for use. Among 10 patients who underwent OSC due to EI, we found overlooked infection sources in 7 (70.0%) at the time of EVAR or during the surveillance period.OSC was performed at a median of 31.8 months (interquartile range, 9.4–69.8) after EVAR as an emergency (15.4%) or elective (84.6%) surgery. Aortic endograft was removed in 84.6% of cases (totally, 57.7%; partially, 26.9%), whereas it was preserved in 4 cases (15.4%). After 26 OSCs, 2 early deaths (7.7%) and 2 aortoenteric fistulae (7.7%) developed as major complications. Conclusion OSC after EVAR was associated with relatively higher perioperative morbidity and mortality. To avoid OSC after EVAR, we recommend careful assessment of coexisting infection sources and avoidance of EVAR for patients with especially unfavorable anatomy for EVAR, particularly the in proximal neck.

We report 17 patients with human granulocytic anaplasmosis between January 2015 and September 2018 at two tertiary university hospitals in Korea. Monthly incidence peaked in May and June. Among these patients, we identified three who were co-infected with scrub typhus, and one patient with hemorrhagic fever with renal syndrome.

PURPOSE: Adventitial cystic disease (ACD) is a rare condition that causes intermittent claudication and non-atherosclerotic disease without cardiovascular risk factors. The etiology and optimal treatment of ACD remain controversial. The purpose of this study was to analyze surgical treatment results for ACD and to elucidate optimal treatment options.MATERIALS AND METHODS: We retrospectively reviewed 30 patients with ACD who underwent surgery from 2006 to 2018. Twenty-two patients had arterial ACD, six had venous ACD, and two had combined venous and arterial ACD. We reviewed demographic and clinical characteristics, treatment details, and procedure outcomes.RESULTS: Recurrence occurred in 6 cases either after cyst excision alone (4/17) or patch angioplasty (2/2). There was no recurrence after vessel excision with interposition grafting (0/7). Therefore, vessel excision was a statistically significant factor in recurrence prevention (P=0.026). Among the six recurrences, joint connections of the cystic lesions were found in four of the six (66.7%).CONCLUSION: As a curative surgery for ACD, vessel excision with interposition grafting is a better strategy to prevent recurrence than simple cyst excision alone.

Purpose: The expression of major histocompatibility complex class I (MHC I) has previously been reported to be negatively associated with estrogen receptor (ER) expression. Furthermore, MHC I expression, level of tumor-infiltrating lymphocytes (TILs), and expression of interferon (IFN) mediator MxA are positively associated with one another in human breast cancers. This study aimed to investigate the mechanisms of association of MHC I with ER and IFN signaling. Materials and Methods: The human leukocyte antigen (HLA)-ABC protein expression was analyzed in breast cancer cell lines. The expressions of HLA-A and MxA mRNAs were analyzed in MCF-7 cells in Gene Expression Omnibus (GEO) data. ER and HLA-ABC expressions, Ki-67 labeling index and TIL levels in tumor tissue were also analyzed in ER+/ human epidermal growth factor receptor 2 (HER2)- breast cancer patients who randomly received either neoadjuvant chemotherapy or estrogen modulator treatment followed by resection. Results: HLA-ABC protein expression was decreased after β-estradiol treatment or hESR-GFP transfection and increased after fulvestrant or IFN-γ treatment in cell lines. In GEO data, HLA-A and MxA expression was increased after ESR1 shRNA transfection. In patients, ER Allred score was significantly lower and the HLA-ABC expression, TIL levels, and Ki-67 were significantly higher in the estrogen modulator treated group than the chemotherapy treated group. Conclusion MHC I expression and TIL levels might be affected by ER pathway modulation and IFN treatment. Further studies elucidating the mechanism of MHC I regulation could suggest a way to boost TIL influx in cancer in a clinical setting.
