호산구성 폐렴은 혈중 호산구가 $1,000/mm^3$ 이상이거나 폐포 내 호산구 분획이 25% 이상으로 나타나는 다양한 폐 질환을 총괄하여 부르는 용어이다. 혈중 호산구증가증은 특발성 급성 호산구 폐렴의 초기나 이미 부신피질호르몬 제제를 투여받은 환자에서는 나타나지 않을 수 있다. 호산구성 폐렴은 무증상의 폐 침윤에서 기계 환기가 필요한 급성 호흡 부전 증후군까지 증상의 중증도도 다양하다. 호산구성 폐렴의 원인으로 약제나 기생충이 있지만 많은 경우 원인을 찾을 수 없다. 폐 외 증상이 동반될 경우 Churg-Strauss 증후군이나 과다호산구증가 증후군의 가능성을 생가해야 되며 이런 경우 심장을 침범하였는지 여부에 따라 예후가 결정된다. 가능한 원인에 대한 노출을 피하는 것 외에는, 부신피질호르몬 제제 투여가 가장 중요하며 대부분 극적인 호전을 보인다. 하지만 약제의 감량 중이나 치료 종결 후 재발하는 경우가 자주 있다. HES의 골수 증식성 변이형 치료에 imatinib의 효과가 최근 입증 되었다.

For the purpose of effective treatment and prevention of porcine respiratory diseases, Enrofloxacin(Baytril premix) was administered in the feed to trial herd occurred sporadically the respiratory diseases and then a serious investigation was carried out on the therapeutic effect, weight gain, feed conversion rate and lung lesion scoring. The results obtained were as follows, 1. The grower pigs which were administered with Baytril premix for 10 days gained the average body weight of 31kg for 33 days compared to 20.5kg of control group(p<0.05). Also drastical improvement of feed conversion rate(p<0.05) and disappearance of clinical signs were approved. 2. Average scorings of lung lesions were 7.92% in the medication group and 15.8% in the control group respectively. 3. Respiratory diseases outbreaked in the trial farm were pleuropneumonia caused by Actinobacillus (Haemophilus)pleuropneumoniae, Mycoplasmal pneumonia and Pasteurellosis.

Bronchiolitis obliterans is a clinical syndrome of chronic obstruction associated with inflammatory changes in the small airways. There are marked variations in the epidemiology of this disease. In childhood, bronchiolitis obliterans has been described as a result of a number of infections such as adenovirus, measles, Bordetella pertussis, Mycoplasma pneumoniae, and influenza A infection. Most common agents are adenovirus types 3, 7, and 21. Diagnosis of bronchiolitis obliterans can be made based on clinical findings, high resolution computed tomography (HRCT) and lung biopsy. In addition to diagnosis, treatment is not yet clearly established. The authors experienced a case of bronchiolitis obliterans developed in 3 year-old girl who suffered from type 7 adenoviral pneumonia. She had been hospitalized and treated for 15 days due to pneumonia. After discharge, productive cough was not improved and auscultation revealed wheezing. HRCT demonstrated multifocal mosaic patterns suggesting bronchiolitis obliterans. She was managed with inhaled steroid and bronchodilator, and her symptoms were improved. However, follow up HRCT showed no interval change.

Hormonal replacement therapy (HRT) has been proven for treatment of postmenopausal symptoms such as hot flushes, night sweats and urologic symptoms. HRT became very popular in the 1990's, when there were several reports showing that it also helped with other menopausal complications such as osteoporosis and cardiovascular disease. Recent studies report that the incidence of breast cancer, endometrial cancer, cerebral infarction, coronary artery diseases, deep vein thrombosis and pulmonary thrombembolism could rise after HRT. Among these side effects of HRT, the risk of pulmonary thromboembolism increases 2 to 4 fold after HRT, but can vary with the use of different doses and preparations. Here, we summarize the risk factors and clinical courses for 5 patients who developed pulmonary thromboembolism after postmenopausal HRT.

Vascular ring, originating from abnormal regression of the aortic arch during fetal life, can cause prolonged and recurrent respiratory symptoms and dysphagia when the diagnosis is delayed. We report a 4 month old girl with vascular ring, who had been treated for persistent respiratory symptoms including stridor, wheezing, and dyspnea soon after birth. Initially her respiratory symptoms were thought to be due to bronchiolitis, for which respiratory syncytial virus was confirmed by immunofluorescent staining. Her clinical course was again complicated with tracheitis and pneumonia due to Haemophilus influenzae type b. The possibility of anatomical anomaly was investigated when it was felt to be difficult to insert a suction catheter deep down through a endotracheal tube which was placed for adequate ventilatory management. A three-dimensional chest CT revealed a vascular ring consisting of a double aortic arch. For 5 months following surgery, her respiratory symptoms have slowly been improving. She developed another episode of pneumonia which was milder than the one which occurred before the surgery.

Purpose: This study aimed to investigate the association between respiratory virus infection and pneumococcal colonization in children. Methods: From May 2009 to June 2010, nasopharyngeal (NP) aspirates were obtained from patients under 18 years old who visited Seoul National University Children's Hospital for respiratory symptoms. NP samples were used to detect respiratory viruses (influenza virus A and B, parainfluenza virus 1, 2 and 3, respiratory syncytial virus A and B, adenovirus, rhinovirus A/B, human metapneumovirus, human coronavirus 229E/NL63 and OC43/HKU1) by RT-PCR and pneumococcus by culture. Results: Median age of the patients was 27 months old. A total of 1,367 NP aspirates were tested for respiratory viruses and pneumococcus. Pneumococcus was isolated from 228 (16.7%) of samples and respiratory viruses were detected from 731 (53.5%). Common viruses were rhinovirus (18.4%), respiratory syncytial virus (RSV) A (10.6%), adenovirus (6.9%), influenza virus A (6.8%). Pneumococcal isolation rate was significantly higher in the cases of positive virus detection than negative detection [21.3% (156/731) vs. 11.3% (72/636), P <0.001]. For individual viruses, pneumococcal isolation rate was positively associated with detection of influenza virus A [24.7% (23/93) vs 16.1% (205/1274), P=0.001], RSV A [28.3% (41/145) vs 15.3% (187/1222), P=0.001], RSV B [31.3% (10/32) vs 16.3% (218/1335), P=0.042], rhinovirus A/B [22.6% (57/252) vs 15.3% (171/1115), P=0.010]. Conclusion: The study revealed that pneumococcal isolation from NP aspirates is related with respiratory virus detection. The result of this study could be used to investigate how respiratory viruses and pneumococcus cause clinical diseases.

Background: We wanted to examine the clinical characteristics of adult patients with tracheobronchial foreign bodies (FBs) according to the risk of aspiration and the outcomes of intervention with using a fiberoptic bronchoscope. Methods: From December 1994 through December 2004 at Kyung Hee Medical Center, we retrospectively analyzed the medical records of 29 adult patients with FBs that were identified by using a fiberoptic bronchoscope. Results: 14 patients were not at risk of aspiration, whereas 15 had cerebrovascular diseases and they were at a high risk of aspiration. No history suggestive of FB aspiration was noted in 7 (24.1%) patients. Respiratory symptom(s) were noted in 22 patients, and these symptoms were cough (62.0%), dyspnea (44.8%), fever (20.7%), wheezing (13.8%), chest pain (10.3%) and hemoptysis (0.4%). Only 60% of those patients at a high risk of aspiration had symptom(s) (92.8% of those patients without a risk of aspiration had symptoms, p=0.005). Those patients at risk for aspiration had a longer duration of symptoms (median: 4 days vs. 2 days for those patients not at risk for aspiration, p=0.007) before diagnosis. Acute respiratory symptom(s) within 3 days after aspiration were more frequent in the patients without a risk of aspiration (9 vs. 4, respectively p=0.048). Chest x-ray revealed radiological abnormalities in 23 patients, and these were opacities suspicious of FB (n=11), pneumonia (n=8), air trapping (n=5) and atelectasis (n=3). There were no differences in radiological findings according to the risk of aspiration. FB aspiration developed most commonly during medical procedures (57.1% for the patients at risk) and during eating (35.7% for the patients without risk). The most common FB materials were teeth (n = 11). Alligator jaw biopsy forceps (n = 23) was the most commonly used equipment. All of the FBs were removed without significant complications. Conclusion: This study underlines that a tracheobronchial FB in the patients who are at a high risk of aspiration are more likely to overlooked because of the more gradual onset of symptoms and the symptoms develop iatrogenically in many cases.

Although diaphragmatic eventration in newborn infants is generally regarded as a rare condition, the need for accurate diagnosis and appropriate intervention according to the etiological factors is well known. Recently the authors experienced five consecutive cases of diaphragmatic eventration below the age of two months(one to 55 days) requiring surgery. All were in males, and were left sided. Respiratory symptoms were present in 4 patients, and one patient showed inability to gain weight. Diaphragms were elevated to the level of the third to fifth intercostal spaces. Diaphragmatic plication through the abdomen gave excellent results. There was no postoperative mortality.

Adenovirus (ADV) and human bocavirus (hBoV) cause acute respiratory tract infections, and are often associated with increased rates of hospitalization and death, particularly in infants and young children. The aim of this study was to analyze the clinical features and molecular phylogeny of ADV and hBoV isolated in Busan, from January 2011 to November 2013. In total, 3,230 specimens (throat swabs) were collected from patients with influenza-like illnesses and acute respiratory tract infections. Multiplex real-time RT-PCR was performed to detect eight respiratory viru [rhinovirus, adenovirus, respiratory syncytial virus, human coronavirus, human metapneumovirus, human bocavirus, parainfluenza virus and influenza virus] and detected 1,485(46.0%) cases. Among 1,485 positive specimens, 257(8.0%) cases were ADV and 68(2.1%) cases of hBoV. A significant clinical feature of ADV is fever and headache whereas hBoV is wheezing. Serotypic distributions of isolated ADV and hBoV were analyzed by sequencing of hexon and VP1/VP2 gene, respectively. ADV was identified seven different serotypes(1~6, 8), revealing a high similarity among the isolates (>97%). The predominant types of ADV were type 1 in 2011, type 3 and 4 in 2012, type 3 in 2013, respectively. ADV type 3 was major causative type during outbreaks in 2013. All of the hBoV was identified as hBoV type 1.
