Objectives : The aim of this study was to investigate the factors related to stress perception. Methods : A self-reported questionnaire was filled out by 109 people living in Gimpo city from January 16 to April 15, 2013. The data were analyzed using SPSS window ver. 19.0(IBM CO., Armonk, NY, USA) for t-test, one-way ANOVA, and multiple linear regression analysis. Results : Men and group of 59 years old tended to have higher stress perception than women and those who over 60 years old, but the results were not statistically significant. Stress perception was higher among the group with systemic dryness and oral dryness(each${\geq}1$) and the group reporting high difficulty in daily living due to oral problem(${\geq}2$)(p<0.05). Especially, the factor that was most correlated to stress perception was systemic dryness(${\beta}$=0.347) followed by problem of daily living for oral problem(${\beta}$=0.278, p<0.01). Conclusions : Systemic dryness and oral problem can increase the level of stress perception, mouth dryness and oral problems are a part of stress responses. Therefore, the regular health checkup must be done and early treatment to reduce stress perception as well as negative aspects caused by stress. It will contribute to the enhancement of public health and life of quality.

Pheochromocytomas and paragangliomas (PPGLs) may secrete hormones or bioactive neuropeptides such as interleukin-6 (IL-6), which can mask the clinical manifestations of catecholamine hypersecretion. We report the case of a patient with delayed diagnosis of paraganglioma due to the development of IL-6-mediated systemic inflammatory response syndrome (SIRS). A 58-year-old woman presented with dyspnea and flank pain accompanied by SIRS and acute cardiac, kidney, and liver injuries. A left paravertebral mass was incidentally observed on abdominal computed tomography (CT). Biochemical tests revealed increased 24-hour urinary metanephrine (2.12 mg/day), plasma norepinephrine (1,588 pg/mL), plasma normetanephrine (2.27 nmol/L), and IL-6 (16.5 pg/mL) levels. ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/CT showed increased uptake of FDG in the left paravertebral mass without metastases. The patient was finally diagnosed with functional paraganglioma crisis. The precipitating factor was unclear, but phendimetrazine tartrate, a norepinephrine-dopamine release drug that the patient regularly took, might have stimulated the paraganglioma. The patient's body temperature and blood pressure were well controlled after alpha-blocker administration, and the retroperitoneal mass was surgically resected successfully. After surgery, the patient's inflammatory, cardiac, renal, and hepatic biomarkers and catecholamine levels improved. In conclusion, our report emphasizes the importance of IL-6-producing PPGLs in the differential diagnosis of SIRS.

Disease flare-up after discontinuing epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) has been considered as a critical issue in lung cancer patients who have experienced radiologic progression after showing initial durable response. This is a case of systemic nocardiosis that occurred after chronic steroid use for radionecrosis from stereotactic radiosurgery. It was initially thought as a disease flare-up after stopping EGFR-TKI.

Alterations in the amino acid structure or sequence can generate neo-epitopes from self-proteins causing autoaggressive immune attack. Reactive nitrogen species are an important factor that induces post-translational modification of proteins by cellular reduction and oxidation mechanism; cysteinyl-nitrosylation or tyrosine nitration leading to potentially pathogenic pathways. It was thought of interest to investigate the immunogenicity of nitrated poly L-tyrosine vis-$\`{a}$-vis its possible role in the induction of antibodies in systemic lupus erythematosus (SLE). Commercially available poly L-tyrosine was exposed to nitrating species and the damage was monitored by UV spectroscopy and alkaline gel electrophoresis. The results indicated the formation of 3-nitrotyrosine. Nitrated poly L-tyrosine induced higher titre antibodies as compared to the native form. Nitrated poly L-tyrosine was recognized by the autoantibodies present in the sera of patients suffering from SLE by enzyme immunoassays and band shift assay. The possible role of nitrated self-proteins has been discussed in the production of circulating anti-DNA antibodies in SLE.

Adult-onset Still's disease (AOSD) is an inflammatory disorder that's characterized by daily, spiking high fever, arthritis and an evanescent, salmon-pink rash. AOSD is diagnosed purely on the basis of the typical clinical features of the illness. The symptoms commonly include swelling of the lymph nodes, enlargement of the spleen and liver, and a sore throat. AOSD is difficult to differentiate from systemic lupus erythematosus (SLE) due to the similar clinical manifestations. We report here on a case of a 16-year-old female patient with autism and epilepsy and who complained of daily spiking fever for 20 days. The patient had maculopapular skin rashes on the face and whole body and lymphadenopathy. The liver function tests were elevated mildly. The initial rheumatoid factor (RF) and antinuclear antibody (ANA) tests were negative. We diagnosed her as having adult-onset Still's disease according to the criteria of Yamaguchi. We successfully treated her with oral prednisolone. But her antinuclear antibody test was changed to positive after discharge. So we finally diagnosed her as having SLE.

Objectives: This study was conducted by clinical dentistry hygienists to develop knowledge measurement tools and evaluate knowledge necessary to cope with emergencies related to systemic diseases occurring in dentistry. Methods: Basic questions were developed on the six most frequently occurring diseases in the dental office: diabetes, syncope, respiratory disease, coronary artery disease, cerebrovascular disease, and epilepsy. Fifty-eight preliminary questions were composed in a survey format through expert validation. The survey was then conducted on 290 dental hygienists to verify the composition validity and reliability. Factor and reliability analyses were performed using the SPSS 23.0 program, and the correct answer rate for each question was calculated. Results: 49 items of a total of 13 factors were adopted as the final items for signs, symptoms, prevention and treatment of five diseases. The question with the highest percentage of correct answers for each question was "Slowly set up the unit chair when raising the patient"(97.9%) during the prevention of unconsciousness and question with the lowest correct answer rate was "soft substances such as cloth should be put in the mouth to prevent trauma while the seizure persists" (16.6%). Conclusions: A total of 49 questions have been developed as tools to measure the knowledge of dental hygienists' first aid related to systemic diseases and it is expected that related curriculum can be operated or evaluated by using them.

This study was conducted to investigate antigenic potential of DA-3030, a recombinant human granulocyte-colony stimulating factor, in guinea pigs and mice. In the active systemic anaphylaxis test, the guinea pigs sensitized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone did not show any anaphylactic reaction. In the homologous passive cutaneous anaphylaxis reaction, anti-DA-3030 antibody was not detected in guinea pigs sensitized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone. On the other hand, the guinea pigs sensitized with 12.5 $\mu\textrm{g}$/heed of DA-3030 incorporated in Freund's complete adjuvant(FCA) or 1 mg/head of ovalbumin incorporated in FCA showed anaphylactic reaction. Anti-DA-3030 antibody was also detected in those guinea pigs. In immunodiffusion test using the sera sensitized with DA-3030 incorporated in FCA, precipitating antibodies were detected only in the sera sensitized with DA-3030 or DA-3030 incorporated in FCA showed. In 24-hour heterologous PCA reaction with sera of C57BL/6 mice immunized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone, none of the sera showed positive reaction. But sera of the animals immunized with 12.5 $\mu\textrm{g}$/head of DA-3030 incorporated in aluminum hydroxide gel(Alum) or 5 $\mu\textrm{g}$/head of ovalbumin incorporated in alum showed positive PCA reaction. DA-3030 did not cause anaphylactic shock or passive cutaneous anaphylaxis in guinea pigs and mice when given alone although DA-3030 incorporated in FCA or Alum induced anaphylactic shock and passive cutaneous anaphylaxis. From these results, it may be concluded the DA-3030 does not induce systemic allergic reaction when administered alone in its clinical use.

Background: In this study, we sought to evaluate whether systemic propentofylline (PPF) has antiallodynic effects in a rat model of postoperative pain, and to assess the mechanism involved. Methods: After plantar incision, rats were intraperitoneally injected with various doses of PPF to evaluate its antiallodynic effect. To investigate the involved mechanism, rats were intraperitoneally injected with yohimbine, dexmedetomidine, prazosin, naloxone, atropine or mecamylamine, following the incision of the rat hind paws, and then PPF was administered intraperitoneally. The mechanical withdrawal threshold (MWT) was evaluated using von Frey filaments at various time points and serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 were measured to determine the inflammatory response level. Results: MWT was significantly increased after intraperitoneal injection of 30 mg/kg of PPF when compared with the control group. Injection of PPF and yohimbine, atropine or mecamylamine showed significant decreases in the MWT, while injection of PPF and dexmedetomidine showed a significant increase. Systemic administration of PPF inhibited the post-incisional increase in serum level of TNF-α and IL-1β. Conclusions: Systemic administration of PPF following surgery presented antiallodynic effects in a rat model of postoperative pain. The antiallodynic effects against mechanical allodynia could be mediated by α-adrenergic and cholinergic receptors.
