Patients undergoing thoracic surgery show various lesions such as chronic obstructive lung diseases, pleural adhesion, pneumonia, acute respiratory distress syndrome, atelectasis, pleural effusion, pulmonary edema, and pneumothorax throughout preoperative, operative, and recovery periods. Therefore, lung ultrasonography has potential for perioperative use in thoracic surgery. Benefits of lung ultrasonography over conventional chest X-ray are convincing. First, ultrasonography has higher sensitivity than X-ray in various lesions. Second, it can be performed at bed side to obtain diagnosis immediately. Third, it does not expose patients to radiologic hazard. If anesthesiologists can obtain necessary skills and perform lung ultrasonography as a routine evaluation process for patients, territory of anesthesia would become broader and patients would obtain more benefit.

The purpose of this study was to report and discuss the diagnosis and treatment of obstructive atelectasis secondary to pus obstruction in a patient who had developed a maxillofacial abscess, and to review the literature on similar cases. Persistently discharging pus within the oral cavity can act as an aspirate, and may lead to obstructive atelectasis. Additionally, maxillofacial surgery patients should be carefully assessed for the presence of risk factors of obstructive atelectasis, such as, epistaxis after nasotracheal intubation, oral bleeding, and mucus secretion. Furthermore, patients with these risk factors should be continuously followed up by monitoring SPO₂, breath sounds, and chest x-ray.

BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

OBJECTIVETo understand the clinical characteristics of allergic bronchopulmonary aspergillosis (ABPA) so as to diagnose and treat the disease earlier.

METHODA retrospective study was conducted on ABPA patients diagnosed in the Second Department of Respiratory Medicine, Beijing Children's Hospital Affiliated to Capital Medical University from April 2010 to March 2014. The literature of children's ABPA retrieved from the databases at home and abroad in recent 10 years were analyzed.

RESULT(1) Among the 4 cases of ABPA, cystic fibrosis (CF) and asthma were diagnosed in 2 and 1 cases, respectively. Cough was present in 3 patients, recurrent wheezing in 2 and chest tightness in 1 case. CT scans showed central bronchiectasis in all 4 cases, while 1 patient had migratory shadows. All cases had elevated serum total IgE, immediate cutaneous reaction to aspergillus fumigatus; A. fumigatus-specific IgE and IgG were positive in 4 cases. The diagnosis of the 4 cases was confirmed according to the history, radiologic investigations and laboratory findings. All of them were improved after the treatment with glucocorticosteroid and antifungal agents (voriconazole or itraconazole). (2) We retrieved articles on the ABPA in the databases at home and abroad published in the recent 10 years, there were 22 foreign reports and only one case in domestic report. Among the 22 foreign cases, 16 patients were CF, 3 were asthmatics. ABPA was diagnosed as the initial presentation in only one case with CF.

CONCLUSIONIn asthmatics or the patients with allergic disease, if there are highly elevated serum total IgE, central bronchiectasis or recurrent atelectasis in chest imaging, the patients should be further investigated for ABPA. The diagnosed cases of ABPA should be screened for CF routinely.

OBJECTIVE: To summarize the specific CT characteristics and the endoscopic findings of primary tracheobronchial amyloidosis (PTBA) for improvement of the diagnostic accuracy.
 METHODS: The imaging features of 6 patients with PTBA were analyzed by multiplanar reconstructed CT and the fiberoptic bronchoscope, and the pathology were summarized retrospectively.
 RESULTS: All PTBA patients received bronchoscopic examination and the definite diagnosis were confirmed by positive staining with Congo red. PTBA presented diffuse thickening of major airway and lumen stenosis in various degrees with scattered hemorrhage of the mucous membrane under CT and bronchoscope, which was more obvious in low part of trachea, main bronchus and lobar bronchus. The mucosa of trachea and bilateral main bronchi were irregular and bumpy with jutting nodes in 5 patients, which was called "wavy path" pattern. Widely nodular or stripy calcifications of airway were found in 4 patients, which was considered as specific imaging features in PTBA and was involved bilateral main bronchi largely. There were obstructive atelectasis in 2 patients, and calcifications of hilus of lung with longitudinal diaphragm lymph nodes in 3 patients, but they were not specific. Ignoring the extensive circumferential thickening of large airway, "wavy path sign" and rail-like calcification was mainly responsible for misdiagnosis of PTBA as endobronchial tuberculosis or other diseases.
 CONCLUSION Attentions to the specific imaging features on multiplanar CT and the endoscopic findings are the fundamentals to avoid the misdiagnosis of PTBA.

PURPOSE: Necrotizing pneumonia (NP) is a complication of invasive pneumonia. Few studies have reported on the clinical features of NP in children. METHODS: Nineteen patients with NP who were admitted to Pusan National University Hospital and Pusan National University Children's Hospital between December 2008 and March 2013, were studied in terms of sex, age at diagnosis, clinical characteristics, detected organisms, radiologic findings, treatments and clinical outcomes. RESULTS: Twelve patients (63.2%) were males and seven patients (36.8%) were female. Eight patients (44.4%) were younger than 5 years of age, seven patients (38.9%) were at 6-10 years of age and four patients (21.1%) were older than 11 years of age. Most patients had fever and cough at the time of diagnosis. Minorganism were identified in 9 cases (47.4%): Mycoplasma pneumonia in 4 (21.1%), Streptococcus pneumonia in 1 (5.3%), Staphylococcus aureus in 1 (5.3%), G+cocci in 1 (5.3%), and M. pneumonia + S. pneumoniae coinfection in 2 (10.5%). The diagnosis of NP was established by computerized tomography. Cavitary necrosis was shown in all patients, and pleural effusion was shown in 15 patients (78.9%). Six patients (31.6%) presented local atelectasis and 2 patients (10.5%) presented pneumothorax. Five patients (26.3%) treated with only antibiotics were cured completely. Invasive treatment was needed by 14 patients (73.7%): 10 patients (52.6%) needed chest tubing, and 5 patients (26.3%) needed surgery. Only one patient (5.3%) expired. CONCLUSION: NP is a rare complication of pneumonia in children and has a good prognosis, typically resolving completely with medical treatment alone. However, patients who present with the worsening of clinical status or pleural complications despite the use of appropriate antibiotics should be evaluated for surgical indications.

Rupture limited to the lobar bronchus from blunt trauma is especially rare, and the symptoms are light so diagnosis is difficult. In a patient who visited the hospital complaining of shortness of breath after falling down, atelectasis continued in the chest x-ray. Four days after visiting the hospital, a left upper lobar bronchial rupture was diagnosed through a bronchoscopy and 3 dimensional chest computerized tomography. When diagnosis is delayed in the case of a rupture limited to the lobar bronchus, bronchial obstruction can occur from the formation of granulation tissue, so regular monitoring is important. Therefore, when atelectasis continues after blunt trauma, it is important to differentially diagnose a lobar bronchial rupture through tests such as bronchoscopy.

OBJECTIVETo analyze the diagnosis and treatment characteristics of patients with severe Influenza A.

METHODA retrospective investigation on the clinical manifestation, chest radiography, electronic fiber bronchoscopy and the histology of the cast, rescue course and outcome was conducted in 15 children with severe influenza A during January to May of 2013.

RESULTEleven cases were male, the range of age was 2 to 6 years; 5 cases were female, the range of age was 1 month to 6 years, accouting for 4.2% of hospitalized children with influenza. Three patients had an underlying chronic disease, two had nephrotic syndrome, and one had congenital heart disease. All the 15 cases were diagnosed as severe influenza A virus infection complicated with pneumonia and respiratory failure, of whom 10 cases were infected with H1N1 virus , the other 5 cases could not be identified as H1N1 virus by using H1N1 kit, but none of the 15 cases were infected with H7N9 virus. Of 15 cases, 8 had atelectasis, 4 had pneumothorax, 3 had pneumomediastinum, 4 had pleural effusion, 1 had pneumorrhagia; 12 patients required mechanical ventilation. 1 only required noninvasive mask CPAP, 2 did not require assisted ventilation, they were just given mask oxygen. Seven cases' sputum culture showed combined infection with bacteria and fungi, sputum smear examination detected: G(+) cocci in 2 cases, and G(-) bacilli in the other 2. By using electronic fiber bronchoscopy, bronchial cast was detected in 5 patiens. Histological examination of the bronchial cast revealed a fibrinous exudation containing large quantity of eosinophils, neutrophils in 1 patients, fibrinous exudation and necrotic material containing large quantity of neutrophils in 4 patients. After the bronchial casts were removed, 4 patients were improved greatly. All patients were treated with postural drainage of left and right side position, massage of electric oscillation, strengthening the sputum suction aiming to improve pulmonary ventilation function. Three patients died: 1 case was compliicated with nephrotic syndrome, another case had congenital heart disease, and 1 case hads pneumorrhagia, renal failure and multiple organ dysfunction syndrome (MODS).

CONCLUSIONThe mortality of severe Influenza A is higher if it is complicated with underlying chronic diseases. In children undergoing rapid and progressive respiratory distress with lung atelectasis, consolidation or emphysema on chest X-ray, plastic bronchitis should be considered. Electronic fiber bronchoscopy should be performed early Lung physicotherapeutics still are important assistant measures for improving the pulmonary ventilation function.
