  • Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.

  • Acute fibrinous and organizing pneumonia is a newly recognized pattern of acute lung injury. A 49-year-old female presented with a cough and worsening dyspnea on exertion. She had no history of smoking and no specific past medical history except exposure of home humidifier containing sterilizer. A chest computed tomography scan showed patchy consolidation with fibrosis in the right lower lobe and ill-defined centrilobular ground glass opacity in both lungs. The pathological findings were patchy areas of lung parenchyma with fibrin deposits in the alveolar ducts and alveoli, and fibrin balls with hemosiderin deposition in the alveolar spaces. The histological pattern of our case is differentiated from diffuse alveolar damage by the absence of hyaline membranes, and from eosinophilic pneumonia by the lack of eosinophils. In our case, the patient was treated with corticosteroid pulse therapy. However, the clinical course became aggravated and she died within two weeks.

  • A 2-month-old male Jeju native black calf with respiratory distress was died and requested to the Veterinary Pathology Laboratory of Jeju National University for diagnosis. Grossly, lungs were focally attached to the pleura and heart with fibrin. Purple red sublobar consolidations were distributed in both apical and cardiac lobes of lungs. Histopathologically, diffuse severe bronchointerstitial pneumonia characterized by multifocal necrotizing bronchiolitis, formation of numerous multinucleated syncytial cells in bronchiolar and alveolar lumens, and diffuse alveolar wall thickening were observed in lungs. Eosinophilic intracytoplasmic inclusions were observed in bronchiolar epithelial cells and syncytial cells. According to reverse transcriptase polymerase chain reaction (RT-PCR), bovine respiratory syncytial virus (BRSV) was detected in the lung of calf. Based on the histopathologic findings and RT-PCR, this calf was diagnosed as BRSV infection. In our best knowledge, this is the first case of BRSV infection in Jeju native black calf.

  • Pathological studies were performed on the five piglets experimentally infected with Aujeszky's disease virus(pseudorabies), NYJ isolate, isolated from the naturally infected pigs in Korea: two piglets were inoculated intramuscularly, two piglets intranasally, and one piglet subcutaneously at the dose of 1$m\ell$ per animal with the 105.5 $TCID_50$/0.1ml titer. Clinical signs included dyspnea, high fever(>$41^{\circ}C$), anorexia, vomiting, diarrhea or constipation, ataxia, circling movement, posterior paralysis, intermittent convulsion, and coma followed by death although some variations by age and inoculated routes were observed. Gross features included multiple necrotic foci in the liver, congestion and hemorrhage in the lymph nodes and spleen, petechial hemorrhage in the kidney, hemorrhagic pneumonia, marked meningeal congestion, severe sub meningeal hemorrhage in the spinal cord, excessive cerebrospinal fluid retention, and muscular necrosis at the inoculated area. Microscopically, non suppurative meningoencephalitis with gliosis and perivascular cuffing in CNS, ganglioneuritis, necrohemorrhagic splenitis, necrotic hepatitis, tonsillitis and rhinitis, hemorrhagic or interstitial pneumonia, and non-suppurative myositis in the injected area were observed. Eosinophilic intranuclear inclusion bodies were found in a variety of tissues the including the liver, kidney, adrenal gland, spleen, lymph nodes, tonsil, and lung. Ultrastructurally, virus particles were confirmed in nucleus and cytoplasms of pneumocytes around the necrotic areas.

  • Background : Open lung biopsy(OLB) has conventionally been regarded as the gold standard for the diagnosis in interstitial lung disease. With recent advances in diagnostic technique such as high resolution computed tomography(HRCT), and transbronchial lung biopsy(TBLB) which provide relatively accurate diagnosis of ILD, it is necessary to reevaluate the role of these methods in the diagnosis of ILD. Methods: We carried out a retrospective analysis of nineteen patients who underwent OLB at Dankook University Hospital for the diagnosis of acute and chronic ILD, between May 1995 and June 1998. By reviewing the medical records, the demographic findings, underlying conditions, HRCT and TBLB findings, OLB diagnosis, therapy after OLB, and complication of OLB were evaluated. Results: Thirteen patients(68.4%) had chronic ILD(symptom duration over 2 weeks prior to OLB), and six patients(31.6%) had acute ILD(symptom duration less than 2 weeks). Specific diagnosis were reached in 92%(12/13) of chronic ILD(5 bronchiolitis obliterans organizing pneumonia(BOOP), 2 constrictive bronchiolitis, 3 usual interstitial pneumonia, 1 hypersensitivity pneumonitis, 1 eosinophilic pneumonia), and in all patients of acute ILD(5 acute interstitial pneumonia, 1 pneumocystis carinii pneumonia). HRCT were performed in all patients and a correct first choice diagnosis rate of HRCT was 42%(5/12) in chronic ILD. In chronic ILD patients, 62%(8/13) received specific therapy(steroid therapy in 7 patients and moving in one patient), after OLB, but in acute ILD, all patients received specific therapy(steroid therapy in 5 patients and steroid and antibiotic therapy in one patient) after OLB. The in-hospital mortality after OLB was 5.3%(1/19). Conclusion: OLB is an excellent diagnostic technique with relatively low complications in patients with ILD. Therefore OLB should be considered in patients with ILD when the specific diagnosis is important for the treatment, especially in patients with acute ILD.

  • A total of 5 animals including 3 raccoons, 1 badger, and 1 fennec fox kept in outdoor exhibits at the Everland Zoological Gardens showed depression, anorexia, dyspnea, serous oculonasal discharge, diarrhea, and convulsions. All the affected animals died within 10 days after the onset of clinical signs. This outbreak lasted about 4 months. On necropsy, major gross lesions were confined to the lungs. Red to grey sublobular to lobular consolidations with various sized tan to reddish spots were observed in the lungs. Histopathologically, the pulmonary lesions were characterized by acute to subacute bronchointerstitial pneumonia with secondary bacterial or adenoviral infections. Intracytoplasmic eosinophilic inclusion bodies compatible with canine distemper virus (CDV) were found in the lung, urinary bladder, kidney, intrahepatic bile duct, stomach, small and large intestines. Multifocal areas of severe demyelination and accumulation of gitter cells or nonsuppurative inflammation were seen in the brains of 2 raccoons. CDV -specific antigens were demonstrated in the lung sections on immunofluorescent assay. The present report describes an outbreak of CDV infection in a zoo and indicates the range of susceptible zoo animal species.

  • Background: Toxocariasis is a common cause of eosinophilia and eosinophilic lung disease in Korea. We analyzed the characteristics of eosinophilic lung disease in toxocariasis. Method: One hundred and forty one patients with eosinophilia caused by a toxocara larval infection were evaluated from September 1, 2001 through March 30, 2006. The plain chest x-ray, chest CT(computed tomography), and bronchoalveolar larvage(BAL) were examined. A diagnosis of toxocariasis was made by ELISA using that secretory-excretory antigen from the T. canis larvae. Results: Toxocarial eosinophilic lung diseases was diagnosed in 32 out of 141 patients. Ground glass attenuation was the main feature on the CT scans in 23 out of 141 patients (71.9%). Thirteen patients (40.6%) had a random in zonal distribution on CT. Pleural effusion was observed in 9 patients (28.1%). Twenty eight patients (87.5%) complained of respiratory symptoms. Eleven patients (34.4%) had gastrointestinal symptoms and 12 patients (37.5%) had liver infiltration. Conclusions: The most common findings of the chest CT in patients with toxocariasis was a randomly distributed ground grass attenuation. A toxocara infection should be considered in a differential diagnosis of patients who exhibit pulmonary infiltration with eosinophilia in Korea.

  • Background: Persistent cough has recently been found to be associated with Chlamydia pneumoniae infection. We aimed to investigate the infection rate of C. pneumonia in adult patients with chronic cough. Methods: We recruited 68 patients with persistent cough lasting in excess of 3 weeks, who visited Kangdong Sacred Heart Hospital from January 2005 to August 2005. On the first visit, chest and paranasal sinuses radiography, skin prick test of common allergens, and induced sputum samples for C. pneumoniae were performed in all of patients. Further evaluation for diagnosis included a methacholine provocation test and eosinophil counts in induced sputum. Results: The most common cause of chronic cough was upper airway cough syndrome (UACS) (26.5%), followed by eosinophilic bronchitis (20.6%) and cough variant asthma (16.2%). Idiopathic chronic cough was the cause in 33.8% of patients. The mean duration of cough was 11.7 months. C. pneumoniae was isolated by polymerase chain reaction (PCR) from one patient who had upper respiratory air way syndrome. Conclusion: Chlamydia pneumoniae appears to have a minor role as a cause of chronic cough in patients.

  • Tetanus is an acute, often fatal, and infectious disease of all species of domestic animals caused by the neurotoxin of Clostridium tetani (C. tetani). This disease is usually known to develop after microbial contamination in the deep or penetrating wound sites. In February 2017, a farmer who was raising 76 cows injected foot and mouth disease vaccine to three or more cows with one syringe. Their clinical symptoms were observed 2 to 16 days after the vaccination. The initial symptoms were stiffness, rigidity of the neck and limbs, pricked ears, and prolapse of the third eyelid. Subsequently, there was recumbency with extension of the limbs, convulsions and opistotonus and the affected 20 cows were all died. Two dead cows were submitted to Animal and Plant Quarantine Agency for disease diagnosis. At necropsy, a focal edematous abscess of 15 to 20 cm in diameter was grossly observed in the subcutaneous and intramuscular tissue of scapular region and filled with a large amount of greenish pus. The feed was full in oral cavity and slightly observed in the trachea and lobes of lung. Histopathologically, focal granulomatous nodules with eosinophilic materials in the tissue were observed. In the lung, aspiration pneumonia and gram (+) bacteria were seen. The C. tetani was isolated in samples anaerobically cultured using reinforced clostridial medium and identified by PCR. To our knowledge, no previous outbreak of tetanus in cattle has affected such a high number of animals; neither has it been associated with misuse of the same syringe and needle to administer multiple individuals.
