BACKGROUND: Kawasaki disease (KD) sometimes presents with only fever and cervical lymphadenopathy before other clinical signs materialize. This lymphadenopathy-first-presenting Kawasaki disease (LKD) may be misdiagnosed as bacterial cervical lymphadenitis (BCL). We investigated characteristic imaging and clinical data for factors differentiating LKD from BCL. METHODS: We compared imaging, clinical, and laboratory data of patients with KD and BCL. We included patients admitted to a single tertiary center between January 2015 and July 2018. RESULTS: We evaluated data from 51 patients with LKD, 63 with BCL, and 218 with typical KD. Ultrasound imaging revealed multiple enlarged lymph nodes in both LKD and BCL patients. On the other hand, computed tomography (CT) showed more abscesses in patients with BCL. Patients with LKD were younger and showed higher systemic and hepatobiliary inflammatory markers and pyuria than BCL patients. In multivariable logistic regression, younger age and higher C-reactive protein (CRP) retained independent associations with LKD. A comparison of the echocardiographic findings in LKD and typical KD showed that patients with LKD did not have a higher incidence of coronary artery abnormalities (CAA). CONCLUSIONS: LKD patients tend to have no abscesses on CT and more elevated systemic hepatobiliary inflammatory markers and pyuria compared to BCL patients. The absence of abscess on CT, younger age, and elevated CRP were the most significant variables differentiating LKD from BCL. There was no difference in CAA between LKD and typical KD.

목 적 : 초기 증상이 발열과 경부림프절종대인 Kawasaki병 환아와 경부 림프절염의 임상적 특징을 비교 관찰함으로써 Kawasaki병의 조기 진단과 치료에 도움을 주고자 하였다. 방 법 : 초기 진단이 임상적으로 경부 림프절염, 경부 농양, 비정형성 Kawasaki병 의증 등으로 치료받다 후에 임상적 진단 기준에 의해 Kawasaki병으로 최종 진단된 환아와 경부 림프절염 환아의 후향적 의무기록 조사를 하였다. 결 과 : 발열과 경부 림프절염이 주증상인 Kawasaki병은 일반적 Kawasaki병 보다 좀 더 나이든 환아에서 발생하였으며, 전신적 염증을 시사하는 소견이 더 높게 나타났다. 경부 림프절염 환아들과 비교하였을 시도 전신적 염증을 시사하는 소견이 의미있게 높았다. 경부 림프절염 환아는 항생제 치료 후 0~3.5일(평균 1.4일)내에 임상적 호전을 보였으나, Kawasaki병의 환아들은 항생제에 반응하지 않거나 다른 소견들이 나타나 입원 1~5일(평균 2.9일)에 감마 글로부린을 사용하였으며, 감마 글로부린 사용 후 평균 11.7시간 내에 발열이 소실되었다. Kawasaki병에서 심장에 나타나는 변화는 3례(20%)였으며, 림프절종대 유무와 관계가 없었다. 결 론 : 발열과 경부 림프절종대를 주소로 경부 림프절염 진단 하에 항생제 치료를 받는 환아 중 항생제에 반응하지 않는 경우, Kawasaki병의 검사실적 소견을 보일 때 다른 감염성 질환 외에 Kawasaki병을 꼭 고려해야 한다. Kawasaki병의 다른 임상적 소견들이 나타나는지 주의 깊게 관찰하여, 신속한 진단과 치료를 통해 심장 합병증을 방지하도록 해야 한다.

The study characterized Trueperella pyogenes (T. pyogenes) from caseous lymphadenitis (CLA) in Korean native goats (KNG). CLA samples (n=191) were obtained from abattoir-slaughtered KNG. Pus were obtained and Corynebacterium pseudotuberculosis was detected by PCR using PLD gene. Three PLD-negative samples (1.57%) from supramammary lymph node were subjected to bacterial culture. Isolates were identified using 16S rRNA and biochemically characterized by APIZYM. Phylogenetic and biochemical analyses identified the isolates as T. pyogenes, and have shown separate clusters and varied enzyme reaction, suggesting genotypic and phenotypic diversity. This first report of T. pyogenes-induced CLA in KNG provided information for further investigations.

목적: 경부 림프절 종대를 먼저 보인 가와사키병(node-first presented Kawasaki disease [NFKD])에 대한 임상 연구를 통해 세균 경부 림프절염(bacterial cervical lymphadenitis [BCL]), 전형적인 가와사키병(Kawasaki disease [KD])과 구별되는 특징을 찾고자 하였다. 방법: 2007년부터 2015년까지 BCL, NFKD, 전형적인 KD로 입원한 환자들의 의무기록을 검토하여 인구학적 특성, 임상 양상, 혈액검사 및 영상의학적 검사 결과를 후향적으로 비교 분석하였다. 결과: 22명의 BCL, 37명의 NFKD, 132명의 전형적인 KD 환자가 연구에 포함되었다. BCL과 NFKD의 비교에서 BCL군의 입원 기간이 더 길었고 NFKD군은 양측, 다발형 림프절 비대를 보이면서 혈소판 수가 적고 호중구 백분율과 CRP 수치가 높았다. NFKD와 전형적인 KD의 비교에서 NFKD군의 나이가 더 많았고 백혈구 수, 호중구 백분율, 호중구 수, CRP 수치가 높고 혈소판 수와 ALT 수치가 낮았다. 결론: 발열과 경부 림프절 종대가 있는 환자에서 호중구 백분율과 CRP 수치가 높고 혈소판 수치가 높지 않으면서 양측, 다발형 경부 림프절 비대를 보인다면, KD의 진단 및 치료가 지연되지 않도록 NFKD 진단을 신속하게 고려하여야 한다.

Caseous lymphadenitis (CLA) is a chronic and contagious disease of sheep and goats caused by Corynebacterium (C.) pseudotuberculosis. A four-year-old female Saanen dairy goat was submitted to the Animal Disease Diagnostic Center at National Veterinary Research and Quarantine Service. The clinical signs of the goat were emaciation, abortion and quadriplegia. The multifocal nodules of lymph nodes were encapsulated and filled with whitish caseous contents on the cut surface. Histopathologically, lymph nodes displayed suppurative and necrotizing granulomas. Caseous necrosis was diffusely observed in the center of the lymph nodes. Gram positive bacilli were shown in the lesions. C. pseudotuberculosis was isolated and confirmed by the biochemical tests and PCR assay. Based on clinical signs, histopathological examination and bacterial isolation, we diagnosed this case as CLA. To our knowledge, this is the first report of CLA in a Saanen dairy goat in Korea.

A female domestic ferret (Mustela putorius furo) presented to a veterinary clinic with a clinical history of anorexia and poor body condition. Due to gradual deterioration of the body condition, explorative laparotomy was performed. Diffusely, the mesentery was severely thickened and adhered with prominent mesenteric lymph nodes. A portion of the mesentery and mesenteric lymph nodes were biopsied and fixed. Microscopic analysis revealed severe pyogranulomatous peritonitis and lymphadenitis, but staining revealed no bacterial organisms. However, immunohistochemistry for feline coronavirus exhibited strong immunoreactivity, primarily in the macrophages. Based on these results, the case was diagnosed as ferret coronavirus infection.

Purpose: With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. Methods: From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. Results: The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Conclusion: Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

Mycobacterium scrofulaceum is an environmental and slow-growing atypical mycobacterium. Emerging evidence suggests that M. scrofulaceum infection is associated with cervical lymphadenitis in children and pulmonary or systemic infections in immunocompromised adults. However, the nature of host innate immune responses to M. scrofulaceum remains unclear. In this study, we examined the innate immune responses in murine bone marrow-derived macrophages (BMDMs) infected with different M. scrofulaceum strains including ATCC type strains and two clinically isolated strains (rough and smooth types). All three strains resulted in the production of proinflammatory cytokines in BMDMs mediated through toll-like receptor-2 and the adaptor MyD88. Activation of MAPKs (extracellular signal-regulated kinase 1/2, and p38, and c-Jun N-terminal kinase) and nuclear receptor (NF)-${\kappa}B$ together with intracellular reactive oxygen species generation were required for the expression of proinflammatory cytokines in BMDMs. In addition, the rough morphotypes of M. scrofulaceum clinical strains induced higher levels of proinflammatory cytokines, MAPK and NF-${\kappa}B$ activation, and ROS production than other strains. When mice were infected with different M. scrofulaceum strains, those infected with the rough strain showed the greatest hepatosplenomegaly, granulomatous lesions, and immune cell infiltration in the lungs. Notably, the bacterial load was higher in mice infected with rough colonies than in mice infected with ATCC or smooth strains. Collectively, these data indicate that rough M. scrofulaceum induces higher inflammatory responses and virulence than ATCC or smooth strains.

Background: The clinical manifestation of $M.$ $tuberculosis$ infection ranges from asymptomatic latent infection, to focal forms with minimal symptoms and low bacterial burdens, and finally to advanced tuberculosis (TB) with severe symptoms and high bacillary loads. We investigated the diagnostic sensitivity of the whole-blood interferon-${\gamma}$ release assay according to the wide spectrum of clinical phenotypes. Methods: In patients diagnosed with active TB that underwent $QuantiFERON^{(R)}$ (QFT) testing, the QFT results were compared with patients known to be infected with pulmonary tuberculosis (P-TB) and extra-pulmonary TB (EP-TB). In addition, the results of the QFT test were further analyzed according to the radiographic extent of disease in patients with P-TB and the location of disease in patients with EP-TB. Results: There were no statistical differences in the overall distribution of QFT results between 177 patients with P-TB and 84 patients with EP-TB; the positive results of QFT test in patients with P-TB and EP-TB were 70.1% and 64.3%, respectively. Among patients with P-TB, patients with mild extents of disease showed higher frequency of positive results of QFT test than that of patients with severe form (75.2% vs. 57.1%, respectively; p=0.043) mainly due to an increase of indeterminate results in severe P-TB. Patients with TB pleurisy showed lower sensitivity by the QFT test than those with tuberculous lymphadenitis (48.8% vs. 78.8%, respectively; p=0.019). Conclusion: Although QFT test showed similar results between overall patients with P-TB and EP-TB, individual sensitivity was different according to the radiographic extent of disease in P-TB and the location of disease in EP-TB.
