Disseminated mycobacterial infection after bacillus Calmette-Guerin (BCG) vaccination is a very rare disorder, occurring mostly in patients with immunologic deficiency. We report a case of disseminated BCG infection in a 16-month-old girl with severe combined immunodeficiency. Plain radiographs showed multiple osteolytic lesions in the femora, tibiae, humerus, and phalanges. Abdominal sonography and CT scanning revealed multiple nodules in the spleen, and portocaval lymphadenopathy.

We report a pediatric patient admitted with abdominal pain, diffuse lower extremity edema and watery diarrhea for two months. Laboratory findings including complete blood count, serum albumin, lipid and immunoglobulin levels were compatible with protein losing enteropathy. Colonoscopic examination revealed diffuse ulcers with smooth raised edge (like "punched out holes") in the colon and terminal ileum. Histopathological examination showed active colitis, ulcerations and inclusion bodies. Immunostaining for cytomegalovirus was positive. Despite supportive management, antiviral therapy, the clinical condition of the patient worsened and developed disseminated cytomegalovirus infection and the patient died. Protein losing enteropathy and disseminated cytomegalovirus infection a presenting of feature in steroid-naive patient with inflammatory bowel disease is very rare. Hypogammaglobulinemia associated with protein losing enteropathy in Crohn's disease may predispose the cytomegalovirus infection in previously healthy children.

Epstein-Barr virus(EBV) infection is common and usually asymptomatic in young infants and children. However, EBV infections in transplant recipients and other immunosuppressed patients can be fatal. EBV-related neurological complications in immunocompetent adults are extremely rare and self-limited. Acute disseminated encephalomyelitis(ADEM) may also follow EBV infection; ADEM is characterized by abrupt onset and rapid progression. We report an immunocompetent adult patient who developed diffuse meningoencephalitis with ADEM-like features caused by EBV infection. A 35-year-old Vietnamese woman was admitted presenting with urinary retention, altered mental status, and paraplegia. PCR of the patient's cerebrospinal fluid showed positive results for EBV. Brain and spine magnetic resonance imaging showed ADEM-like features. She was treated with acyclovir, steroid, and immunoglobulins. We report the case of an immunocompetent adult Vietnamese woman who presented with rapidly progressive diffuse meningoencephalitis associated with EBV infection and was treated with antivirals, corticosteroids, and immunoglobulins.

BCG는 M. bovis로부터 유래된 생백신으로 5-6세 미만의 소아 결핵 특히 결핵성 수막염이나 속립성 결핵과 같은 중증 결핵의 예방 효과가 인정되고 있다. BCG 접종 후 이상반응은 국소 궤양 형성, 국소 림프절염이 가장 흔하며, 드물지만 골수염, 파종성 감염과 같은 치명적인 합병증도 있다. 파종성 BCG 감염은 주로 면역저하 환자에게서 흔하게 관찰되며 면역 저하가 없는 소아에게서 발생한 파종성 BCG 감염은 국내 문헌상 보고가 없었다. 저자들은 13개월 여환이 BCG 접종 5개월 뒤 발생한 발열, 피부 결절 및 다발성 림프절 종대를 주소로 내원하여, 백 신 접종 부위 외에 2군데에서 M. bovis BCG를 확인한 후 파종성 BCG 감염으로 진단된 1례를 경험하였다. 환아는 isoniazid와 rifampin으로 치료받았으며 약 2주 간의 입원 치료 후 임상 증상이 호전되어 퇴원하였다. 3주뒤 외래 추적 관찰에서 역설적 반응으로 생각되는 림프 절 종대와 피부 결절이 진행하였으나 동일 약제를 유지하면서도 다시 임상 증상이 호전되었고 환아의 면역학적 검사상 이상 소견이 관찰되지 않았기에 이를 보고하는 바이다.

Treatment guidelines for postnatal cytomegalovirus (pCMV) infection in preterm have not been established yet. Neutropenia, thrombocytopenia, hepatitis, colitis, and sepsis-like disease are among the clinical manifestations, which range from moderate to serious. We present a case of autopsy diagnosed as pCMV infection in a premature infant delivered at gestational age of 24 weeks and 5 days. On the 7th and 14th days of birth, urinary CMV polymerase chain reaction samples were negative, ruling out congenital CMV infection. However, autopsy examination revealed that the patient had disseminated pCMV infection. CMV inclusion bodies were found in the majority of tissues, including the lung, liver, pancreas, breast, kidney, and adrenal gland, but not the placenta. The thymus exhibited significant cortical atrophy and T-cell immunodeficiency, possibly induced by dexamethasone treatment for bronchopulmonary dysplasia or by pCMV infection itself. If dexamethasone treatment is extended or high doses are considered, it may be beneficial to test the CMV infection status to prevent aggravation of infection. This case demonstrates that, despite the low prevalence, pCMV infection should be considered a differential diagnosis in preterm if other conditions or etiology cannot justify clinical deterioration.

Herpes zoster is a cutaneous infection that is characterized by an acute vesicobullous rash with ipsilateral one or two dermatomal distribution and painful allodynia, while predominantly being found in the elderly. Extensive cutaneous dissemination has been reported in immune-compromised patients, such as those who suffer from HIV infections, cancer, chemotherapy, and corticosteroid therapy patients. However, we report a case of disseminated herpes zoster infection in an immuno-competent elderly individual.

Purpose: Tuberculosis (TB) is one of the most important diseases that cause significant mortality and morbidity in young children. Data on TB transmission from an infected child are limited. Herein, we report a case of disseminated TB in a child and conducted a contact investigation among exposed individuals. Methods: A 4-year-old child without Bacille Calmette-$Gu{\acute{e}}rin$ vaccination was diagnosed as having culture-proven disseminated TB. The child initially presented with symptoms of inflammatory bowel disease, and nosocomial and kindergarten exposures were reported. The exposed individuals to the index case were divided into 3 groups, namely household, nosocomial, or kindergarten contacts. Evaluation was performed following the Korean guidelines for TB. Kindergarten contacts were further divided into close or casual contacts. Chest radiography and tuberculin skin test or interferon-gamma-releasing assay were performed for the contacts. Results: We examined 327 individuals (3 household, 10 nosocomial, and 314 kindergarten contacts), of whom 18 (5.5%), the brother of the index patient, and 17 kindergarten children were diagnosed as having latent TB infection (LTBI). LTBI diagnosis was more frequent in the children who had close kindergarten contact with the index case (17.1% vs. 4.4%, P=0.007). None of the cases had active TB. Conclusion: This is the first reported case of TB transmission among young children from a pediatric patient with disseminated TB in Korea. TB should be emphasized as a possible cause of chronic diarrhea and failure to thrive in children. A national TB control policy has been actively applied to identify Korean children with LTBI.

A 2-year-old outdoor, spayed, female Korean Jindo dog was referred for thoracic and abdominal masses. Diagnostic imaging revealed generalized lymphadenopathy and a significant amount of pleural effusion. The cytological evaluation of the pleural effusion and fine-needle aspiration of the mediastinal lymph nodes confirmed the presence of fungal hyphae. The histopathological examination of the mediastinal lymph nodes stained with Grocott's methenamine silver revealed fungal mycelia, and Aspergillus terreus was identified based on fungal DNA sequencing. Thus, the dog was diagnosed with disseminated canine aspergillosis caused by A. terreus. This case report describes a rare case of disseminated canine aspergillosis caused by A. terreus in a Korean Jindo dog.

Acute disseminated encephalomyelitis (ADEM) and acute hemorrhagic leukoencephalitis (Hurst's disease) are rare autoimmune demyelinating disorders, which show a monophasic illness with preceding infection. We report a 42-year-old woman presented with multiphasic and progressive neurologic deterioration without definite evidences of infection. She developed hypesthetic ataxia, followed by ipsilateral weakness after a weak, and finally encephalopathy after a month. In contrast to the first MRI showing a small longitudinal lesion, the next images revealed massive bilateral frontal lesions with hemorrhagic necrosis and biopsy unveiled inflammatory demyelination.
