The orbital neurilemmoma originates exclusively from Schwann cells of the cranial nerve, any myelinated peripheral nerve, and sympathetic nerve. The incidence of this benign neoplasia is reported as rare and arises usually in the intraconal. A 28-year-old female complained of lid swelling and palpable mass on the right upper lid for a period of 8 months. The mass wsa excised totally and histopathologic examination revealed a typical neurilemmoma(Schwannoma). In this case, there was no proptosis because the mass was located extraconally. It is to report a rate case of extraconal neurilemmoma of the orbit.

Several studies have shown that curcumin, which is derived from the rhizomes of turmeric, possesses antimicrobial, antioxidant and anti-inflammatory properties. The antitumor properties of curcumin have also now been demonstrated more recently in different cancers. This study was undertaken to investigate the modulation of cell cycle-related proteins and the mechanisms underlying apoptosis induction by curcumin in the SCC25 human tongue squamous cell carcinoma cell line. Curcumin treatment of the SCC25 cells resulted in a time- and dose-dependent reduction in cell viability and cell growth, and onset of apoptotic cell death. The curcumin-treated SCC25 cells showed several types of apoptotic manifestations, such as nuclear condensation, DNA fragmentation, reduced MMP and proteasome activity, and a decreased DNA content. In addition, the treated SCC25 cells showed a release of cytochrome c into the cytosol, translocation of AIF and DFF40/CAD into the nuclei, a significant shift in the Bax/Bcl-2 ratio, and the activation of caspase-9, caspase-7, caspase-6, caspase-3, PARP, lamin A/C, and DFF45/ICAD. Furthermore, curcumin exposure resulted in a downregulation of G1 cell cycle-related proteins and upregulation of p27KIP1. Taken together, our findings demonstrate that curcumin strongly inhibits cell proliferation by modulating the expression of G1 cell cycle-related proteins and inducing apoptosis via proteasomal, mitochondrial, and caspase cascades in SCC25 cells.

OBJECTIVES: The aim of this study is to develop guideline for evaluation of depression. METHODS: Development of this guideline was processed according to the ADAPTE manual, which was developed for adaptation of good clinical practice guidelines. Important key questions were determined, and a systematic review of clinical practice guidelines was performed. The contents of guidelines selected by comparison of the methodological quality and currency were evaluated with regard to the applicability and acceptability. Answers to key questions and clinical recommendations were established by peer review. RESULTS: Careful evaluations on the characteristics of depression, including subtype, severity, suicidality, and psychiatric and physical comorbidities were recommended because these factors can have an influence on course and prognosis in treatment of depression. CONCLUSION: The results of this study may contribute to the systematic evaluation of depression, based on clinical importance. However, this guideline did not include systematic reviews regarding useful scales for evaluation of depression. In the future, amendment of this guideline might be needed in order to supplement limitations.

OBJECTIVES: The aim of this study is to develop guideline for use in diagnosis of depression. METHODS: Development of this guideline was processed according to the ADAPTE manual, which was developed for adaptation of good clinical practice guidelines. Important key questions were determined, and a systematic review of clinical practice guidelines was performed. The contents of guidelines selected by comparison of the methodological quality and currency were evaluated with regard to the applicability and acceptability. Answers to key questions and clinical recommendations were established by peer review. RESULTS: There has been no evidence on strategies to improve the accuracy and rate of diagnosis of depression. The screening tools for depression were useful in diagnosis of depression in clinical practice. CONCLUSION: The results of this study may suggest the necessity of strategies to improve the validity and reliability of diagnosis of depression. In contrast, scales for screening depression can be useful in diagnosis of depression. This guideline did not include systematic reviews regarding useful scales for diagnosis of depression. In the future, amendment of this guideline might be needed in order to supplement limitations.

BACKGROUND AND PURPOSE: The one-day rivastigmine patch is reportedly well tolerated and has minimal side effects. However, Asian patients show more side effects than those in Western countries. We evaluated tolerability of the rivastigmine patch in South Korean patients with Alzheimer's disease (AD) and the specific factors affecting adverse events of the skin. METHODS: A 6-month, open labeled, multi-centered, observational study was carried out in 440 patients with probable AD from July 2009 to September 2010 (NCT01312363). RESULTS: A total of 25.9% of the patients experienced adverse skin events at the rivastigmine patch application site and 17.0% discontinued treatment due to adverse events at the skin application site. The most common adverse events were itching and erythema. Patients with an allergic history and users of electric heating appliances reported skin discomfort. Older age was associated with discontinuing treatment. CONCLUSION: These results suggest that the rivastigmine patch induced some adverse skin events and may contribute to understanding and improving skin tolerability to the rivastigmine patch.

Resistance to hypomethylating agents (HMAs) in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) is a concerning problem. Polo-like kinase 1 (PLK1) is a key cell cycle modulator and is known to be associated with an activation of the PI3K pathway, which is related to the stabilization of DNA methyltransferase 1 (DNMT1), a target of HMAs. We investigated the effects of volasertib on HMA-resistant cell lines (MOLM/AZA-1 and MOLM/DEC-5) derived from MOLM-13, and bone marrow (BM) samples obtained from patients with MDS (BM blasts >5%) or AML evolved from MDS (MDS/AML). Volasertib effectively inhibited the proliferation of HMA-resistant cells with suppression of DNMTs and PI3K/AKT/mTOR and ERK pathways. Volasertib also showed significant inhibitory effects against primary BM cells from patients with MDS or MDS/AML, and the effects of volasertib inversely correlated with DNMT3B expression. The DNMT3B-overexpressed AML cells showed primary resistance to volasertib treatment. Our data suggest that volasertib has a potential role in overcoming HMA resistance in patients with MDS and MDS/ AML by suppressing the expression of DNMT3 enzymes and PI3K/AKT/mTOR and ERK pathways. We also found that DNMT3B overexpression might be associated with resistance to volasertib.

Safe and effective sedation depends on various factors, such as the choice of sedatives, sedation techniques used, experience of the sedation provider, degree of sedation-related education and training, equipment and healthcare worker availability, the patient’s underlying diseases, and the procedure being performed. The purpose of these evidence-based multidisciplinary clinical practice guidelines is to ensure the safety and efficacy of sedation, thereby contributing to patient safety and ultimately improving public health. These clinical practice guidelines comprise 15 key questions covering various topics related to the following: the sedation providers; medications and equipment available; appropriate patient selection; anesthesiologist referrals for high-risk patients; pre-sedation fasting; comparison of representative drugs used in adult and pediatric patients; respiratory system, cardiovascular system, and sedation depth monitoring during sedation; management of respiratory complications during pediatric sedation; and discharge criteria. The recommendations in these clinical practice guidelines were systematically developed to assist providers and patients in sedation-related decision making for diagnostic and therapeutic examinations or procedures. Depending on the characteristics of primary, secondary, and tertiary care institutions as well as the clinical needs and limitations, sedation providers at each medical institution may choose to apply the recommendations as they are, modify them appropriately, or reject them completely.

Background and Objectives:
De-escalation of dual-antiplatelet therapy through dose reduction of prasugrel improved net adverse clinical events (NACEs) after acute coronary syndrome (ACS), mainly through the reduction of bleeding without an increase in ischemic outcomes. Whether the benefits of de-escalation are sustained in highly thrombotic conditions such as ST-elevation myocardial infarction (STEMI) is unknown. We aimed to assess the efficacy and safety of de-escalation therapy in patients with STEMI or non-STsegment elevation ACS (NSTE-ACS).
Methods:
This is a pre-specified subgroup analysis of the HOST-REDUCE-POLYTECH-ACS trial. ACS patients were randomized to prasugrel de-escalation (5 mg daily) or conventional dose (10 mg daily) at 1-month post-percutaneous coronary intervention. The primary endpoint was a NACE, defined as a composite of all-cause death, non-fatal myocardial infarction, stent thrombosis, clinically driven revascularization, stroke, and bleeding events of grade ≥2 Bleeding Academic Research Consortium (BARC) criteria at 1 year.
Results:
Among 2,338 patients included in the randomization, 326 patients were diagnosed with STEMI. In patients with NSTE-ACS, the risk of the primary endpoint was significantly reduced with de-escalation (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.48– 0.89; p=0.006 for de-escalation vs. conventional), mainly driven by a reduced bleeding. However, in those with STEMI, there was no difference in the occurrence of the primary outcome (HR, 1.04; 95% CI, 0.48–2.26; p=0.915; p for interaction=0.271).
Conclusions
Prasugrel dose de-escalation reduced the rate of NACE and bleeding, without increasing the rate of ischemic events in NSTE-ACS patients but not in STEMI patients.

Pediatric differentiated thyroid cancers (DTCs), mostly papillary thyroid cancer (PTC, 80-90%), are diagnosed at more advanced stages with larger tumor sizes and higher rates of locoregional and/or lung metastasis. Despite the higher recurrence rates of pediatric cancers than of adult thyroid cancers, pediatric patients demonstrate a lower mortality rate and more favorable prognosis. Considering the more advanced stage at diagnosis in pediatric patients, preoperative evaluation is crucial to determine the extent of surgery required. Furthermore, if hereditary tumor syndrome is suspected, genetic testing is required. Recommendations for pediatric DTCs focus on the surgical principles, radioiodine therapy according to the postoperative risk level, treatment and follow-up of recurrent or persistent diseases, and treatment of patients with radioiodine-refractory PTCs on the basis of genetic drivers that are unique to pediatric patients.
