OBJECTIVES: This study compared attitudes toward antipsychotic treatment according to awareness of the name of their illness in patients with schizophrenia. METHODS: Information on sociodemographic and clinical characteristics, including awareness of the importance of antipsychotic treatment, was obtained through a self-report questionnaire. The Drug Attitude Inventory (DAI) was administered. The data were compared according to awareness of the name of their illness. RESULTS: The study analyzed data for 199 patients with schizophrenia. Of these, 115 patients (57.8%) were aware that their illness was called schizophrenia, while 84 patients (42.2%) knew it by their psychotic symptoms or as another mental illness, such as depression. The patients aware of the name of their illness had significantly longer durations of illness and higher scores on the DAI. They were significantly more likely to have stopped taking medication on their own accord and to agree with the importance of antipsychotic treatment. Statistical significance was sustained in a logistic regression analysis after adjusting for the duration of illness and study site, except for the DAI score, which had borderline significance (p=0.055). In subjects with duration of illness > or =5 years, patients aware of the name of their illness had significantly higher scores on the DAI. CONCLUSION: Awareness of the name of their illness was associated with awareness of the importance of, and a positive attitude toward, antipsychotic treatments in patients. Psycho-education, including telling the patient the correct name of his or her illness, might be needed for maintaining antipsychotic treatment in patients with chronic schizophrenia.

Aberrant breast tissue is usually found in proximity to the normal breast, that is, in the axillary, sternal or clavicular regions. Carcinoma occurs more frequently in the aberrant tissue of the axilla than the extra-axillary site though the overall incidence of tumors of aberrant breast tissue is low. To our knowledge, studies regarding the carcinoma of aberrant breast tissue of the extra-axillary site have been reported rarely. Here we report a recent case of carcinoma originating from the extra-axillary aberrant breast tissue, presenting as a subcutaneous nodule on the right upper anterior chest wall. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be suspected for breast carcinoma as a differential diagnosis and treated properly.

Purpose: The goal of this study was to follow benign thyroid nodules confirmed by ultrasound (US)-guided core needle biopsy (CNB) after inconclusive cytology on fine-needle aspiration (FNA) biopsy. Methods: Sixty-two thyroid nodules from 62 patients with CNB-confirmed benign histology that initially had inconclusive cytology on FNA were retrospectively included. The thyroid nodules were followed for 38.7 months (median, 27.5 months; range, 6 to 101 months), and the US findings of biopsied nodules, such as the interval change in size, US characteristics, and imaging category based on the Korean Thyroid Imaging Reporting and Data System (K-TIRADS), were evaluated. In addition, patients’ clinical records were reviewed for any further management or newly diagnosed thyroid malignancy. Results: Among 62 cases, three (4.8%) showed interval size growth, while 59 (95.2%) demonstrated no interval change or a decrease in size. There was no upgrade of K-TIRADS category or any newly diagnosed malignancy during the follow-up period. Conclusion US-guided CNB-confirmed benign thyroid nodules with inconclusive cytology on FNA showed a stable status during follow-up, and repeated CNB could be helpful in the management of nodules with inconclusive cytology on FNA.

Reducing [Mg2+]o to 0.1 mM can evoke repetitive [Ca2+]i spikes and seizure activity, which induces neuronal cell death in a process called excitotoxicity. We examined the issue of whether cultured rat hippocampal neurons preconditioned by a brief exposure to 0.1 mM [Mg2+]o are rendered resistant to excitotoxicity induced by a subsequent prolonged exposure and whether Ca2+ spikes are involved in this process. Preconditioning by an exposure to 0.1 mM [Mg2+]o for 5 min inhibited significantly subsequent 24 h exposure-induced cell death 24 h later (tolerance). Such tolerance was prevented by both the NMDA receptor antagonist D-AP5 and the L-type Ca2+ channel antagonist nimodipine, which blocked 0.1 mM [Mg2+]o-induced [Ca2+]i spikes. The AMPA receptor antagonist NBQX significantly inhibited both the tolerance and the [Ca2+]i spikes. The intracellular Ca2+ chelator BAPTA-AM significantly prevented the tolerance. The nonspecific PKC inhibitor staurosporin inhibited the tolerance without affecting the [Ca2+]i spikes. While Go6976, a specific inhibitor of PKCalpha had no effect on the tolerance, both the PKCepsilon translocation inhibitor and the PKCzeta pseudosubstrate inhibitor significantly inhibited the tolerance without affecting the [Ca2+]i spikes. Furthermore, JAK-2 inhibitor AG490, MAPK kinase inhibitor PD98059, and CaMKII inhibitor KN-62 inhibited the tolerance, but PI-3 kinase inhibitor LY294,002 did not. The protein synthesis inhibitor cycloheximide significantly inhibited the tolerance. Collectively, these results suggest that low [Mg2+]o preconditioning induced excitotoxic tolerance was directly or indirectly mediated through the [Ca2+]i spike-induced activation of PKCepsilon and PKCxi, JAK-2, MAPK kinase, CaMKII and the de novo synthesis of proteins.

Increasing evidence implicates changes in [Ca²⁺]i and oxidative stress as causative factors in amyloid beta (Aβ)-induced neuronal cell death. Cyanidin-3-glucoside (C3G), a component of anthocyanin, has been reported to protect against glutamate-induced neuronal cell death by inhibiting Ca²⁺ and Zn²⁺ signaling. The present study aimed to determine whether C3G exerts a protective effect against Aβ₂₅₋₃₅-induced neuronal cell death in cultured rat hippocampal neurons from embryonic day 17 fetal Sprague-Dawley rats using MTT assay for cell survival, and caspase-3 assay and digital imaging methods for Ca²⁺, Zn²⁺, MMP and ROS. Treatment with Aβ25–35 (20 µM) for 48 h induced neuronal cell death in cultured rat pure hippocampal neurons. Treatment with C3G for 48 h significantly increased cell survival. Pretreatment with C3G for 30 min significantly inhibited Aβ₂₅₋₃₅-induced [Zn²⁺]i increases as well as [Ca²⁺]i increases in the cultured rat hippocampal neurons. C3G also significantly inhibited Aβ₂₅₋₃₅-induced mitochondrial depolarization. C3G also blocked the Aβ₂₅₋₃₅-induced formation of ROS. In addition, C3G significantly inhibited the Aβ₂₅₋₃₅-induced activation of caspase-3. These results suggest that cyanidin-3-glucoside protects against amyloid β-induced neuronal cell death by reducing multiple apoptotic signals.

PURPOSE: Allergic rhinitis (AR) is one of the common chronic diseases. Although it is not a life-threatening disease, its persistent symptoms may cause fatigue, mood change, discomfort at work, and academic disability as well as the decrease of quality of life. The prevalence of AR has been increasing steadily due to the Westernized lifestyle and environmental change. In previous studies, it has been found that AR has a clear relationship with smoking. However, there is no relationship study between AR and electronic cigarettes smoking (ECS). METHODS: The study was conducted on >19-year-old adults who participated in the 2015 Korea National Health and Nutrition Examination Survey. Sex, age, residence status, tobacco smoking, alcohol drinking, stress level, economic status, and diagnosis of AR were analyzed by using univariate and multivariate logistic regression analyses. RESULTS: AR tended to be associated with ECS in the Korean adult population in univariate analysis, but ECS was not statistically significant in multivariate analysis. By multivariate analysis, AR was significantly related with younger age, male sex, alcohol consumption, and stress. Moreover, the prevalence of AR was linearly decreased as age increased from 19 to 69 years. CONCLUSION: A diagnosis of AR was not significantly associated with ECS. Instead, AR showed an increased prevalence in adults at younger age, of male sex, and with alcohol consumption and high stress. To derive statistically significant results of relationship between AR and ECS, more well-designed studies focusing on the temporal causal are needed.

BACKGROUND: Peripheral blood stem cells (PBSCs) are mobilized by granulocyte-colony stimulating factor (G-CSF), which causes several side effects in allogeneic donors. We report on side effects of G-CSF administration and determine which side effects could be used in predicting the amount of harvested CD34+ cells. METHODS: Data from the first PBSC collections of 155 healthy donors between 2007 and 2010 were analyzed. Side effects were assessed using adverse event inventory, which was graded from 1 (mild) to 3 (severe) or 4 (disabling). RESULTS: G-CSF administration caused an elevation of WBC counts (mean 44,834/microL) and 86% of them were neutrophils. The mean mononuclear cells in apheresis products was 6.6x10(8)/kg and mean CD34+ cells was 6.0x10(6)/kg. Bone pain was reported by 151 healthy donors (97%) and severe bone pain was related to more CD34+ cells in apheresis products (P=0.041): 39 for grade 1 (5.1x10(6) CD34+cells/kg), 86 for grade 2 (6.0x10(6)), and 26 for grade 3 (7.1x10(6)). In addition, the percentage of collecting more than 5.0x10(6) CD34+cells/kg during the first leukapheresis showed correlation with the severity of bone pain. CONCLUSION: Bone pain was the most common side effect of G-CSF mobilization and more CD34+ cells were harvested in cases of severe bone pain.
