Bacterical tracheitis is a very rare complication in adults after endotracheal intubation. We report a case of bacterial tracheitis associated with endotracheal intubation and corticosteroids. The patient was discharged with a permanent tracheostomy, and a resection and an end-to-end anastomosis of the trachea is planned.

The tracheostomy directs external air into the airway tract. This process causes mucosal dryness, irritation and inflammation in the tracheo-bronchial tree. In order to prevent such problems, several methods are applied; ointment application, humidification and careful suction etc. The heat-moisture exchanger (HME) is commercially sold device that assists heating and humidification of the inhaled air. The authors experienced successful treatment outcome of intractable tracheitis caused by repetitive and vigorous intra-tracheal suction by applying HME in a total laryngectomized patient. We report an interesting and didactic case with a brief literature review.

Background: This study aimed to analyze and describe the morbidity and mortality associated with tracheostomy in patients with oral cancer and to identify the risk factors associated with tracheostomy complications. Methods: We performed a retrospective chart review of patients who underwent tracheostomy during a major oral cancer resection between March 2001 and January 2016 at the National Cancer Center, Korea. Overall, we included 51 patients who underwent tracheostomy after oral cancer surgery. We assessed the morbidity and mortality of tracheostomy and determined the risks associated with tracheostomy complications. Results: Twenty-two tracheostomy-related complications occurred in 51 patients. The morbidity and mortality rates were 35.2 % (n = 18) and 0 % (n = 0), respectively. Tracheostomy-related complications were tracheitis (n = 4), obstructed tracheostomy (n = 9), displaced tracheostomy (n = 5), air leakage (n = 1), stomal dehiscence (n = 1), and decannulation failure (n = 2). Most complications (19/22) occurred during the early postoperative period. Considering the risk factors for tracheostomy complications, the type of tube used was associated with the occurrence of tracheitis (p < 0.05). Additionally, body mass index and smoking status were associated with tube displacement (p < 0.05). However, no risk factors were significantly associated with obstructed tracheostomy. Conclusions: Patients with risk factors for tracheostomy complications should be carefully observed during the early postoperative period by well-trained medical staff.

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.

Aspergillus infection is the most common cause of death due to fungi in immunocompromised hosts. Aspergillus tracheobronchitis is an uncommon but severe form of invasive pulmonary aspergillosis, which is limited entirely or mainly to the tracheobronchial tree and can often be life-threatening. We report a case of a 54-year-old man who died from Aspergillus tracheobronchitis without an underlying disease. Autopsy revealed an extensive yellowish plaque adhering to the trachea and bronchial wall. The microscopic examination of the trachea and bronchus revealed septate branching hyphae of Aspergillus.

The superiorly based flap tracheostomy(SBFT) has been advocated as an new technique of tracheostomy to manage a wide variety of causes of upper airway obstruction. This technique has particular applicability in patients who require long term tracheostomy such as in bilateral vocal cord paralysis and severe obstructive sleep apnea. SBFT has numerous advantages such as shortening of the gap between the skin and trachea : construction of a self-sustaining tract ; circumferential mucocutaneous junction to reduce infection, granulation tissue, bleeding, and stenosis of the tract : avoidance of the laryngotracheal damage : easy placement of a tracheostomal stent to promote speech, coughing and swallowing. Most of all, this technique can reduces the suprastomal buckling by the support of the superiorly based tracheal flap, and thus prevents the stenosis of suprastomal airway. The disadvantage of SBFT is more time-consuming procedure than the conventional tracheostomy, A retrospective analysis of 8 patients undergoing SBFT between June, 1994 and March, 1995 in Dankook University Hospital was performed to present the surgical technique and com-plication rates. The average duration of follow up was 11 months. The complications were consisted of a wound infection and a sternal granulation. The other complications including wound dehiscence, tracheitis, pneumonia, tracheal granulation, sternal narrowing and subglottic stenosis were not experienced.

A total of 3 hybridoma clones producing monoclonal antibody (MCA) against infectious laryngotracheitis virus (ILTV) was established by somatic cell hybridization between mouse myeloma cells and spleen, cells from mice immunized with ILTV. The MCAs were screened by the indirect flourescent antibody (IFA) staining and the specific hybridomas were cloned by limiting dilution method. The MCAs produced by the 3 hybriomas were all classified as immunogloblin G and found to be reacting against common antigen(s) of high and low pathogenic ILTV examined. The titer of these antibodies in mouse ascitic fluid was from $10^5$ to $10^6$. Indirect fluorescent antibody test using these antibodies was found to be quite effective for the detection of ILTV from infected chickens being the most sensitive among the test methods adopted.

Smoke toxicity is the test for the toxicity evaluation of smoke and hazardous gas, caused by combustion of building materials and finishing materials. Smoke toxicity can be evaluated by the mean incapacitation time of mice. This test result can be influenced by the health status of mice and test condition. In acute inhalation toxicity test of hazardous gas, no typical clinical findings and histopathologic abnormalities were observed. Tracheitis and bronchitis as well as acute lung inflammation around terminal bronchiole in some mouse of the highest dose group. Through this study, we established the method for inhalation toxicity test of hazardous gas as well as the SOP of inhalation toxicity test. However, in the future studies, the concentration control methods for inhalation technologies on hazardous gas will be needed to improve continuously and also further studies on other gas inhalation toxicity will be needed to conduct.

Tremella aurantialba, one of edible and medicinal mushrooms belonging to Tremellaceae of Basidiomycota, has been known to have outstanding curing effects on coughing, tracheitis and hypertension of humans and antitumor activity on the sarcoma 180 and Erhrlich carcinoma of mice. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to Fr. NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from fruiting body of the mushroom. In vitro cytotoxicity tests showed that all crude polysaccharides extracted from the fruiting body were not cytotoxic against cancer cell lines such as RAW 309 CR.1 and Sarcoma 180 at the concentration of $2000\;{\mu}g/ml$. Intraperitoneal injection with crude polysaccharides exhibited life prolongation effect of $11.1{\sim}66.7%$ in mice inoculated with Sarcoma 180. Fr. MeOH improved the immunopotentiation activity of B lymphocyte by increasing the alkaline phosphatase activity by 1.16 folds at the concentration of $200\;{\mu}g/ml$. In case of Fr. HW, the numbers of peritoneal exudate cells and circulating leukocytes were increased by 1.42 and 2.87 folds, respectively.
