  • 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.

  • Purpose: Methimazole is an anti-thyroid drug that can cause life-threatening neutropenia in rare situations. The aim of this case report is to describe a set of oral complications associated with methimazole-induced neutropenia and the healing of the gingiva after proper treatment. Methods: A 31-year-old female patient hospitalized for systemic symptoms of sore throat and fever and showing extensive gingival necrosis with pain was referred to the Department of Periodontics from the Department of Endocrinology. Methimazole-induced neutropenia was diagnosed based on blood test results and her medical history. Methimazole was discontinued and a range of treatments was administered, including the injection of granulocyte colony stimulating factor. Results: After systemic treatment, the gingiva began to heal as the neutrophil count increased. Approximately one year later, the gingiva had returned to a normal appearance. Twenty-one months after treatment, sequestra of the alveolar bone that had broken through the gingiva were removed. Periodic supportive periodontal treatment has been continued uneventfully. Conclusions: The oral manifestations of gingival necrosis and ulcerations, in combination with systemic symptoms such as fever and sore throat, are the critical signs presented in the early stages of drug-induced neutropenia. Therefore, dentists need to be aware of these oral complications in order to make an accurate diagnosis and to ensure that prompt medical intervention is provided.

  • 헤노흐-쇤라인 자반증(HSP)은 소아에서 가장 흔한 혈관염으로 피부 자반증, 관절염, 복통, 그리고 신염 등을 특징으로 한다. HSP 소아에서 물집을 동반하는 경우는 매우 드물다. 관절염을 동반한 HSP를 보인 9세 여아에서 경구용 스테로이드 치료를 시작했음에도 불구하고 피부 자반이 빠르게 출혈성 물집 병변으로 진행되었다. 치료 7일 후 몇몇 궤양성 병변은 경미한 흉터로 남았으나 관찰 6개월 후 흉터는 완전히 소멸되었다. 현미경적 혈뇨는 관찰 6개월간 지속되었으나 단백뇨는 관찰되지 않았다. HSP 소아에서 물집이 동반되었을 경우, 신장의 예후에는 직접적인 연관은 없었다. 임상적으로 HSP 진단기준을 만족한다면 HSP 진단을 위해 피부조직검사는 필요 없을 것으로 보이며, 더 많은 증례가 모이면 정확한 결론을 내릴 수 있을 것으로 사료된다. 관절염을 동반한 HSP 9세 여자 소아에서 경구용 스테로이드 치료를 시작했음에도 불구하고 피부 자반이 빠르게 출혈성 물집 병변으로 진행되는 HSP 증례를 경험하였기에 보고하는 바이다.
