Abstract
RATIONALE The patient in this case report has been diagnosed with multidrug resistant lymph node fistula tracheobronchial tuberculosis (TBTB). The PubMed was searched using the keywords "Tuberculosis, Multidrug-Resistant", "Tuberculosis", and "Bronchial Fistula", and the results yielded no similar case reports. Therefore, this report helps us to explore more on the causes of multidrug resistance and formation of lymph node fistula, as well as associated treatment strategies. PATIENT CONCERNS A 15-year old Tibetan girl who was previously treated in the local Hospital for Infectious Diseases for repeated TBTB demonstrated poor treatment outcomes, and so was further diagnosed in our hospital. After standard treatments, the cough and expectoration of the girl showed improvement, and mycobacterium culture showed negative results. Thoracic CT showed local compression of the right bronchus, and disappearance of stenosis. Bronchoscopy showed that the fistula was closed and healed. DIAGNOSES Multidrug resistant lymph node fistula TBTB. INTERVENTIONS Antituberculosis drugs such as pyrazinamide (0.75 g/time, twice per day), moxifloxacin (0.4 g per day), protionamide enteric-coated tablets (0.2 g/time, 3 times per day), pasiniazide tablets (0.3 g/time, 3 times per day), and capreomycin (0.75 g per day) were orally administered. The treatment included an 8-month intensive treatment phase and a 12-month consolidation phase. Bronchoscopic local injection combined with cryotherapy was also conducted. OUTCOMES Bronchoscopy showed that the fistula was closed and healed, mycobacterium culture showed negative results, and thoracic CT showed local compression of the right bronchus, disappearance of stenosis after treatment. LESSONS (1) This girl had a history of long-term oral intake of antituberculosis drugs, but the treatment effectiveness remained poor. Therefore, resistance to tuberculosis can be considered, and also mycobacterium culture and drug sensitivity tests should be considered. After these, the treatment strategies should be adjusted accordingly.(2) TBTB should be further classified by analyzing under the bronchoscope to decide the best treatment strategy accordingly.

Abstract
RATIONALE Every year, ∼40,000 people suffer burn-related injuries in the United States. Despite recent advances, the odds of dying from exposure to fire, flames, or smoke are one in ∼1500. Smoke inhalation causes injury to the airways via a complex physiological process, and the treatment is mainly supportive. Many recent interventions aim to decrease the formation of fibrin casts, the main cause of airway damage in these patients. Among these, treatment with a combination of nebulized heparin and N-acetylcysteine (NAC) has shown benefit. PATIENT CONCERNS We describe the case of a 58-year-old man who presented after smoke inhalation during a fire. Soot was found in the nostrils when he was admitted to our hospital, and after he began coughing up carbonaceous material, he was electively intubated and placed on volume assist control ventilation. DIAGNOSIS Bronchoscopy on the first day of intensive care confirmed the injury from smoke inhalation and revealed mucosal edema and soot involving the tracheobronchial tree. INTERVENTIONS AND OUTCOMES Inhaled unfractionated heparin of 10,000 IU in 3 mL of 0.9% normal saline alternating every 2 hours with 3 mL of 20% NAC was started 48 hours after admission and continued for 7 days. Bronchoscopy on the fifth day of intensive care showed significant improvement in airway edema and a resolution of soot. LESSONS On the basis of our experience with this case and limited literature, we posit that nebulized heparin and NAC may be of benefit in patients with inhalational smoke-induced lung injury and mild-to-severe lung injury scores.

A comparative study of the beneficial effects of ipratropium and beclomethasone against insulin-induced tracheal tissue contraction in a guinea pig model. Med Princ Pract 2015; 24:92-5. [PMID: 25278282 PMCID: PMC5588183 DOI: 10.1159/000366259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2013] [Accepted: 08/03/2014] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE To evaluate the acute effects of insulin on airway reactivity and the protective effects of beclomethasone and ipratropium against insulin-induced airway hyperresponsiveness on isolated tracheal smooth muscle in a guinea pig model. MATERIALS AND METHODS The trachea of each guinea pig was excised; one end of the tracheal strip was attached to the hook of the oxygen tube of a tissue bath and the other end was connected to a research-grade isometric force displacement transducer. The effects of varying concentrations of insulin (10(-7) to 10(-3)M) and insulin pretreated with a fixed concentration of beclomethasone (10(-6)M) and ipratropium (10(-6)M) on the isolated tracheal tissue were studied by constructing cumulative concentration-response curves. Changes in tracheal smooth muscle contractions were recorded on a 4-channel oscillograph. RESULTS The means ± standard error of the mean of the maximum amplitude of contraction with increasing concentrations of insulin and of insulin pretreated with fixed concentrations of beclomethasone and ipratropium were 35 ± 1.13, 22 ± 1.15 and 27.8 ± 1.27 mm, respectively. CONCLUSION The data showed that beclomethasone inhibited the contractile response of insulin to a greater extent than ipratropium. Thus we suggest that inhalational insulin pretreated with beclomethasone may be more efficacious than with ipratropium for the amelioration of potential respiratory adverse effects such as bronchoconstriction.

Abstract
Tracheal diverticulum, defined as a benign outpouching of the tracheal wall, is rarely diagnosed in clinical practice. It can be congenital or acquired in origin, and most cases are asymptomatic, typically being diagnosed postmortem. We report a case of a 69-year-old woman who was hospitalized after presenting with fever, fatigue, pleuritic chest pain, and a right neck mass complicated by dysphagia. Her medical history was significant: pulmonary emphysema (alpha-1 antitrypsin deficiency); bronchiectasis; and thyroidectomy. On physical examination, she presented diminished breath sounds and muffled heart sounds, with a systolic murmur. Laboratory tests revealed elevated inflammatory markers, a CT scan showed an air-filled, multilocular mass in the right tracheal wall, and magnetic resonance imaging confirmed the CT findings. Fiberoptic bronchoscopy failed to reveal any abnormalities. Nevertheless, the patient was diagnosed with tracheal diverticulum. The treatment approach was conservative, consisting mainly of antibiotics. After showing clinical improvement, the patient was discharged.

Abstract
Background and Study Aims Tracheobronchopathia osteochondroplastica (TO) is an uncommon disease of the tracheobronchial system that leads to narrowing of the airway lumen from cartilaginous and/or osseous submucosal nodules. The aim of this study is to perform a detailed review of this rare disease in a large cohort of patients with TO proven by fiberoptic bronchoscopy from China. Patients and Methods Retrospective chart review was performed on 41,600 patients who underwent bronchoscopy in the Department of Respiratory Medicine of Changhai Hospital between January 2005 and December 2012. Cases of TO were identified based on characteristic features during bronchoscopic examination. Results 22 cases of bronchoscopic TO were identified. Among whom one-half were male and the mean age was 47.45±10.91 years old. The most frequent symptoms at presentation were chronic cough (n = 14) and increased sputum production (n = 10). Radiographic abnormalities were observed in 3/18 patients and findings on computed tomography consistent with TO such as beaded intraluminal calcifications and/or increased luminal thickenings were observed in 18/22 patients. Patients were classified into the following categories based on the severity of bronchoscopic findings: Stage I (n = 2), Stage II (n = 6) and Stage III (n = 14). The result that bronchoscopic improvement was observed in 2 patients administered with inhaled corticosteroids suggested that resolution of this disease is possible. Conclusions TO is a benign disease with slow progression, which could be roughly divided into 3 stages on the basis of the characteristic endoscopic features and histopathologic findings. Chronic inflammation was thought to be more important than the other existing plausible hypotheses in the course of TO. Inhaled corticosteroids might have some impact on patients at Stage I/II.

Abstract
A 74-year-old man was referred to our hospital because of a tracheal stenosis circumscribed with soft tissue density and a left pulmonary nodule. Open biopsy of a right submandibular lymph node revealed diffuse large B-cell lymphoma, and the malignant cells were positive for Epstein-Barr virus gene products. Bronchofiberscopy revealed a tracheal necrotizing ulcer. After chemotherapy, the tracheal ulcer resolved. To our knowledge, this is the first report of a case of Epstein-Barr virus-positive diffuse large B-cell lymphoma of the elderly with a tracheal ulcer.

Abstract
Endotracheal involvement of tuberculosis (TB), a type of endobronchial TB, is defined as granulomatous infection of the tracheobronchial tree. We present the case of a 33 year-old female agriculture engineer with endotracheal tuberculosis (ETTB). It was treated successfully with prompt long-course antituberculous medication without complications or need for endotracheal intervention. This unusual case of ETTB, diagnosed promptly by fiberoptic bronchoscopy, and microbiological studies, is presented to emphasize the importance of macroscopic recognition to start anti-TB therapy in cases with significant airway obstruction. This case is important for countries where the various presentations of TB are encountered as well as in countries where TB is not endemic.

Abstract
Extranodal marginal zone lymphoma is a low-grade B cell lymphoma that presents with an indolent clinicopathologic nature. Although this tumor can occur in various sites, including the gastrointestinal tract and lungs, it develops and spreads extremely rarely along the trachea and central airway. We report a case of extranodal lymphoma of mucosa-associated lymphoid tissue with tracheobronchial involvement. An 83-year-old woman presented with a cough and dyspnea. Bronchoscopic evaluation confirmed diffuse, multiple nodular lesions in both the trachea and large bronchi, and she was diagnosed with an extranodal marginal zone lymphoma of the tracheobronchial tree. After systemic chemotherapy, she survived for more than 18 months.

Abstract
INTRODUCTION The impact on tracheal anatomy and respiratory function of recombinant human (rh)TSH-stimulated (131)I therapy in patients with goiter is not clarified. METHODS In a double-blinded design, patients (age 37-87 yr) with a large multinodular goiter (range, 99-440 ml) were randomized to placebo (n = 15) or 0.3 mg rhTSH (n = 14) 24 h before (131)I therapy. The smallest cross-sectional area of the trachea (SCAT; assessed by magnetic resonance imaging) and the pulmonary function were determined before, 1 wk, and 12 months after therapy. RESULTS Data on goiter reduction have been reported previously. In the placebo group, no significant changes in the lung function or SCAT were found throughout the study. In the rhTSH group, a slight decrease was observed in the forced vital capacity 1 wk after therapy, whereas the mean individual change in SCAT was significantly increased by 10.5% (95% confidence interval = 0.9-20.0%). A further increase in SCAT to 117 +/- 36 mm(2) (P = 0.005 compared with 92 +/- 38 mm(2) at baseline) was seen at 12 months, corresponding to a mean of 31.4% (95% confidence interval = 16.0-46.8%). The expiratory parameters did not change significantly, whereas forced inspiratory flow at 50% of the vital capacity (FIF50%) increased from initially 3.34 +/- 1.33 liters/sec to ultimately 4.23 +/- 1.88 liters/sec (P = 0.015) in the rhTSH group, corresponding to a median increase of 24.6%. By 12 months, the relative improvements in FIF50% and in SCAT were inversely correlated to the respective baseline values (FIF50%: r = -0.47, P = 0.012; SCAT: r = -0.57, P = 0.001). CONCLUSION On average, neither compression of the trachea nor deterioration of the pulmonary function was observed in the acute phase after rhTSH-augmented (131)I therapy. In the long term, tracheal compression is diminished, and the inspiratory capacity improved, compared with (131)I therapy alone.

Abstract
An elderly woman with post-tuberculous stricture of the lower trachea and main bronchi underwent laser re-canalization, balloon dilation, and silicone stent insertion in the lower trachea and main bronchi. Subsequently she had recurrent dyspnea develop due to obstructing granulomas, which necessitated four endoscopic procedures in 2 years. The tracheal stent was removed and topical mitomycin-C was applied using saturated pledgets at a dose of 0.5 mg/mL for 2 minutes each over the lower trachea and both orifices of the main bronchi. Follow-up for 24 months showed no recurrence of symptoms. Bronchoscopy and spirometry performed at 2, 6, and 12 months showed resolution of the granulomas.

Persistence of Mycoplasma hyopneumoniae in experimentally infected pigs after marbofloxacin treatment and detection of mutations in the parC gene. Antimicrob Agents Chemother 2006; 50:1959-66.

Abstract
The ability of Mycoplasma hyopneumoniae to persist despite fluoroquinolone treatments was investigated with pigs. Groups of specific-pathogen-free pigs were experimentally infected with M. hyopneumoniae strain 116 and treated with marbofloxacin at the therapeutic dose (TD) or half of the therapeutic dose (TD/2) for 3 days. Results showed that, despite tissue penetration of marbofloxacin, particularly in the trachea and the tracheal secretions, the treatments did not have any influence on M. hyopneumoniae recovery from tracheal swabs. Mycoplasmas were also isolated from inner organs and tissues such as liver, spleen, kidneys, and bronchial lymph nodes. Recontamination of pigs via environment could not explain mycoplasma persistence after medication, as decontamination of pigs and allocation to a new disinfected environment did not have any significant effect on the phenomenon. A significant decrease in the susceptibility level to marbofloxacin of 12 mycoplasma clones reisolated after the treatments (TD/2 and TD) was observed. Two point mutations were found in the ParC quinolone resistance-determining region (QRDR) of DNA topoisomerase IV (Ser80-->Phe and Asp84-->Asn), and one point mutation was observed just behind the QRDR of ParC (Ala116-->Glu). This is the first time that mutations in a gene coding for topoisomerase IV have been described for M. hyopneumoniae after in vivo marbofloxacin treatments in experimentally infected pigs. However, development of resistance is not sufficient to explain M. hyopneumoniae persistence in vivo since (i) marbofloxacin concentrations were above the marbofloxacin MIC of the wild-type strain and (ii) mycoplasmas reisolated after a single injection of marbofloxacin did not display an increased marbofloxacin MIC.

Abstract
Tracheobronchial candidosis is an impetuous complication in intensive care medicine. This article presents a concept to compare diagnostic procedure, Candida species and resistant species of different intensive care units with each other. This concept should encourage bench marking between similar intensive care units. The report and retrospective analysis of the intensive care course offer the opportunity to reflect own decisions and to adjust them to the current therapy strategies. Both procedures should improve the antimycotic therapy for intensive care units and should avoid the occurrence of resistant species. Candida species are often detected in the respiratory system of ventilated patients in intensive care, but this alone is no indication for antimycotic therapy. A strict retention is recommended, but this retention is diminished by an unclear infection, critical situation of the patient in the case of multiple organ failure, additional infection and long term ventilation. A therapy strategy for individual situations should be established and a close diagnostic procedure should be performed. A positive blood culture or detection of Candida species in two or more diagnostic materials indicate an early antimycotic therapy.

Abstract
BACKGROUND The aim of this study was to determine the impact of nosocomial tracheobronchitis (NTB) related to new bacteria on the outcome in patients with chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS A prospective observational case-control study was conducted in medical COPD patients requiring intubation and mechanical ventilation for more than 48 hours. Patients with nosocomial pneumonia were excluded. Six matching criteria were used, including the duration of mechanical ventilation before NTB occurrence. RESULTS 81 matched case-control pairs were studied. Although the mortality rate was similar (40% vs 34%; p = 0.48), median duration of mechanical ventilation (20 vs 12 days; p = 0.015) and intensive care unit (ICU) stay (25 vs 18 days; p = 0.022) were higher in cases than in controls. NTB was independently associated with a longer than median period of mechanical ventilation among case and control patients (OR = 4.7 [95%CI = 2-10.9]; p < 0.001). In cases with appropriate antibiotic treatment compared with those who did not receive antibiotics, a shorter median duration of mechanical ventilation (12 vs 23 days; p = 0.006) and ICU stay (16 vs 29 days; p = 0.029) were observed. CONCLUSION NTB is associated with an increased duration of mechanical ventilation and ICU stays. Further studies are required to determine whether antibiotics could improve the outcome of patients with NTB.

Abstract
Tracheomalacia (TM) is associated with expiratory airway collapse and potentially fatal respiratory distress. Internal and external tracheal stents and, recently, resorbable biopolymers have been used to treat this condition. In this study, the efficacy and biocompatibility of internal Palmaz stents and external poly-L-lactic acid-polyglycolic acid (PLPG) stents were compared in a model of severe TM induced in piglets. The tracheas were repaired with one of two stenting methods, and the animals survived for up to 16 weeks. Weight gain, adverse respiratory signs and symptoms, tracheal or lung histopathologic changes, and internal and external tracheal diameters were measured. The animals in the PLPG group uniformly were free of respiratory distress and tracheal stenosis or inflammation, whereas all animals in the Palmaz group developed respiratory distress as a result of pneumonia or tracheal stenosis caused by intraluminal granulation tissue. In conclusion, superior efficacy of external, resorbable PLPG stents was found relative to internal Palmaz stents for the surgical repair of severe TM.

Abstract
Pseudomembranous tracheobronchial aspergillosis coincident with systemic pulmonary aspergillosis represents a rare manifestation of fungal infection in immunocompromized hosts. We report on a patient with recurrent Hodgkin's disease, showing this infectious pattern after treatment with corticosteroids within the antineoplastic schedule, whereas neutropenia--the main risk factor for mold infections--had not occurred. An impaired number of helper T lymphocytes was merely detected as an additional, but hypothetical risk factor, when investigating the status of immunosuppression. Treated systemically with amphotericin B, the patient recovered quickly, although reported mortality rates are disastrous. What is crucial for the clinical management is an early diagnosis by bronchoscopy and cultural proof of the pathogen followed by an adequate antifungal treatment.

Abstract
We investigated whether saber sheath-type tracheomalacia could be treated by the slow release of bone morphogenetic protein (BMP)-2 from a gelatin sponge. A 1 cm gap was made in the middle portion of each of 10 consecutive tracheal cartilage rings in the canine cervix (control group, n = 3), then a gelatin sponge containing 12 microg of BMP-2 solution was implanted in the gap (12 microg group, n = 3). In another group (120 microg + P group, n = 3), the implanted gelatin sponge contained 120 microg of BMP-2 solution, and the gap was covered with periosteum. All of the control dogs developed saber sheath-type tracheomalacia, whereas tracheomalacia was not observed in the 12 microg and 120 microg + P groups. In the 12 microg group, fibrous cartilage was observed at the ends of the cartilage stumps. In the 120 microg + P group, newly formed bone and cartilage were observed to form a bridge between the cartilage stumps. The regeneration of cartilage or bone induced by the slow release of BMP-2 from a gelatin sponge might be useful for treatment of tracheomalacia.

Abstract
Inflammatory bowel disease is a systemic illness that may involve the lung. The most common manifestation of pulmonary involvement is an asymptomatic reduction in lung transfer factor for carbon monoxide (Dlco) and a small airway disorders easy to find in subjects with active disease. Some patients show a bronchial inflammation and suppuration with or without bronchiectasis poorly responsive to antibiotics but responding dramatically to inhaled steroids. Others present a severe tracheal inflammation and obstruction with an inflammatory mass bulging into the tracheal lumen, these subjects usually respond to methylprednisolone, in rare cases an emergency laser ablation may be necessary. Interstitial lung disease and pulmonary infiltrate with eosinophilia are the most difficult patterns to address because in some cases drugs such as sulfasalazina and 5-aminosalicylate may play a contributing role.

Abstract
BACKGROUND We report 10 cases of active endobronchial tuberculosis in female patients. PATIENTS AND METHODS Diagnosis of endobronchial tuberculosis was established by demonstrating the presence of Koch bacilli in the bronchial washings or at pathology examination of a bronchial mucosa biopsy. Follow-up was available for 5 of the 10 cases. RESULTS These women were aged 19 to 756 years. Clinical signs included persistent cough (n=10), wheezing (n=10), dyspnea (n=5), dysphonia (n=4) and fever (n=8). Chest x-ray was normal in 4 cases but showed condensation in 4 others with infiltration of the superior lobe in 2 cases. Bronchoscopy findings were characteristic with a thick layer of white caseum on the mucosa. Koch bacilli were found in all bronchial wash specimens. Pathology examination confirmed the diagnosis of tuberculosis in 5 of the 10 cases.

Abstract
Wegener's granulomatosis (WG) is a clinicopathologic entity of unknown cause characterised by a necrotising granulomatous vasculitis affecting multiple organs, especially the upper and lower respiratory tracts, lung and kidney. The lung is the most frequently, and sometimes the only involved organ. Single or multiple nodules, with or without cavitation, are the most common pulmonary manifestations in WG, but mediastinal involvement is atypical. The sole tracheal involvement is rare and hilar and mediastinal involvement has been thought not to be part of the clinical feature. We experienced a rare case of WG presenting as paratracheal mediastinal lesions with tracheal wall invasion, which responded dramatically to corticosteroid treatment. We present this case with a review of the literature.

Abstract
A case of endotracheal tuberculosis with expectorations of the lateral one-third of the multiple tracheal cartilages is reported. Fibreoptic bronchoscopy revealed caseous materials and loosening of the tracheal cartilages. The patient expectorated cartilaginous material several times before and after fibreoptic bronchoscopy. In spite of the loss of tracheal cartilages, tracheal lumen was maintained with a mild airflow limitation. The remaining two-thirds of the tracheal cartilage rings seemed to be strong enough to support the tracheal lumen opening during the respiratory cycle. Although rare, expectoration of bronchial cartilage can be one of the clinical features of endobronchial tuberculosis.

Abstract
Infection due to Coccidioides immitis usually begins in the lungs. Despite the initial pulmonary portal of entry, endotracheal and endobronchial coccidioidomycosis has rarely been described. Since the introduction of fiberoptic bronchoscopy and the AIDS epidemic, more C. immitis lesions of the large airways have been noted. We present data on 38 cases of coccidioidomycosis of the airways, including 6 cases detailed from our own experience and 32 from the literature. Direct infection of the airways (28 cases) is a more common mechanism of airways disease than is erosion into the airways from a lymph node (5 cases). Bronchoscopic findings vary and may show mucosal involvement or intrinsic obstruction. Endotracheal and endobronchial disease is not a self-limited disease and requires antifungal therapy. Disseminated disease in these patients is common. Coccidioidomycosis must be considered in the differential diagnosis of airway pathology.

Abstract
We studied the effect of AM-1155, a newly developed quinolone, against chronic airway infection with Pseudomonas aeruginosa using a previously described rat model. AM-1155 (25 mg/kg) or ciprofloxacin (25 mg/kg) or saline (controls) were injected s.c. for 14 days (from day 4 to day 17) after the inoculation of agar beads containing P. aeruginosa. The number of viable cells of intrapulmonary P. aeruginosa, histological findings of the lungs and immunoglobulin levels of serum and bronchoalveolar lavage fluid were examined in rats 11 and 18 days after the treatment. The findings indicated that the number of viable cells of P. aeruginosa in lungs was significantly decreased in the AM-1155- or ciprofloxacin-treated group compared with the non-treated control group. Histological examination in the non-treated control group showed hyperplasia of bronchus-associated lymphoid tissue as well as cellular infiltration in airways, but not prominently in the AM-1155- or ciprofloxacin-treated group. The IgG and IgA levels in serum and bronchoalveolar lavage fluid were significantly lower in the AM-1155- and ciprofloxacin-treated groups than in the control group. These in-vivo effects of AM-1155 were comparable to those of ciprofloxacin. These findings suggest that treatment with AM-1155 and ciprofloxacin suppressed excessive immune responses, preventing progression of airway damage in the chronic infectious state.

Abstract
Tracheomalacia is a congenital or acquired deficiency of the cartilages of the trachea. Treatment procedures include formation of external support by insertion of cartilage; bone for foreign material into the peritracheal tissue. A sclerosing agent, sodium morrhuate, was injected in the peritracheal tissue, blindly or after skin incision and subcutaneous tissue. In both groups peritracheal granulation tissue and inflammation evolved into peritracheal fibrosis surrounding the cartilage at the site of injection. The reaction was more pronounced following incision of the skin. No fibrosis was observed in a control group following hypertonic saline injection. The results suggest that injection of sclerosing agents might be considered as a conservative mode of treatment in tracheomalacia, by producing peritracheal fibrosis as external support.

Abstract
The action of the anti-asthmatic drug sodium cromoglycate (SCG) on airway inflammation remains uncertain. Using Evans blue dye as a maker of plasma leakage, we studied the effect of SCG on neurogenic vascular extravasation evoked by hypertonic saline (HTS) in the rat trachea. Inhalation of HTS (5-15%) caused a concentration-dependent increase in plasma leakage, but inhaled 0.9% NaCl had no effect. Inhalation of SCG did not affect the baseline level of vascular permeability, but it inhibited the effect of HTS in a dose-dependent manner: plasma extravasation induced by 10% NaCl was significantly reduced by 2 minutes of inhalation of SCG at concentrations of 10 and 50 mg/ml (p < 0.05 and p < 0.01, respectively). SCG (10 mg/ml), also inhibited the changes in microvascular permeability caused by aerosols of substance P (10(-4) M), whereas it did not affect the responses to aerosols of platelet-activating factor (3 x 10(-4) M). A similar dose of SCG did not significantly alter microvascular leakage caused by 5% NaCl. However, phosphoramidon, a selective inhibitor of neutral endopeptidase, potentiated the response to 5% NaCl, an effect that was inhibited by SCG (p < 0.05). These results suggest that SCG inhibits HTS-induced airway vascular permeability, presumably through a tachykinin-antagonist-like property, and that this inhibition is exaggerated when the activity of endogenous neutral endopeptidase is low.

Abstract
The clinical features of tracheobronchial tuberculosis are distinct from those of pulmonary tuberculosis in some aspects. Streptomycin (SM) is claimed by some investigators that it has a tendency to promote the development of bronchial stenosis. The purpose of the present investigation is to point out that aerosol therapy of SM is useful for patients with tracheobronchial tuberculosis. Prior to clinical application of the inhalation therapy, we confirmed that the therapy was not harmful. Serum concentration of SM, when inhaled, was measured in 9 volunteers. Before and after administration of SM aerosol, spirograms were examined in 4 volunteers, and no special abnormality was recognized. It seemed that serum concentration of SM after the administration was too low to evoke adverse reactions (less than 3.0 gamma). In 6 patients, blood gases were measured, and no obvious change was observed. In 41 patients with bronchial tuberculosis, bronchofiberscopic examinations were performed twice or more. We observed the ulcerous lesions of bronchial tuberculosis at various stages of healing, and could classify the ulcerous lesions into the following three stages. Active Stage: stage A; ulcer formation without regenerating epithelium, Healing Stage: stage H; ulcer formation with regenerating epithelium, Scarring Stage: stage S; and no ulcer formation. Only the lesions of stage A were observed before treatment. In many patients during the first and second month of treatment, the lesions were at stage A or H. It was found that healing of the lesions of tracheobronchial tuberculosis progressed through the stages A, H, and S, in this order.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 55-year-old man developed multiple erythematous skin lesions after surgery for acoustic neurinoma. Necrosis and detachment of the epidermis developed and a diagnosis of toxic epidermal necrolysis (TEN) was made. Progressive dyspnea was evident two days after the onset of the skin lesions. Chest X-ray revealed diffuse interstitial shadows in both lung fields. On bronchoscopic examination, erosion, vesicle formation, necrosis and desquamation of the epidermis were seen in the tracheobronchial mucosa. Therapy, including prednisolone, improved the skin lesions as well as the chest X-ray and bronchoscopic findings. Tracheobronchial and pulmonary lesions were followed before, during and after treatment of TEN.

Abstract
The beta 2-adrenergic agonist formoterol has been shown to inhibit plasma extravasation in the respiratory mucosa associated with neurogenic inflammation as well as that caused by histamine or bradykinin. It is unknown whether these effects of formoterol are mediated through an action of sensory nerves or through a direct effect on the leaky blood vessels. In the present study we sought to determine whether capsaicin-sensitive sensory nerves are essential for the anti-edema effect of formoterol in the rat trachea. Substance P (5 micrograms/kg), PAF (hexadecyl-PAF, 5 micrograms/kg), or bradykinin (10 mg/kg) was injected intravenously to increase vascular permeability. The amount of plasma extravasation was measured with two tracers, Evans blue dye and Monastral blue pigment. The effectiveness of formoterol's anti-edema action was assessed in two groups of rats. One was pretreated with capsaicin to eliminate tachykinin-containing sensory nerves and another, the control group, was not pretreated. We found that in control rats formoterol inhibited to a similar extent the extravasation of Evans blue and Monastral blue caused by all three mediators. The highest intravenous dose of formoterol (10 micrograms/kg) reduced substance P-induced extravasation of Monastral blue by 59%, reduced PAF-induced extravasation by 74%, and reduced bradykinin-induced extravasation by 58%. Pretreatment of rats with a dose of capsaicin that eliminated at least 94% of the substance P-immunoreactive nerve fibers did not significantly reduce the effectiveness of formoterol against any of the mediators.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Out of 404 patients with pulmonary and/or tracheobronchial tuberculosis treated during the last 10 years at Kurume University Hospital and St. Mary Hospital, in 41 patients, who had been histopathologically or bacteriologically diagnosed as having active tracheobronchial tuberculosis, tracheobronchial lesions were examined by use of bronchofiberscope. Most patients were treated by a combination of three antituberculous agents (INH, RFP and SM or EB). In 31 patients out of the 41 patients, broncho-fiberscopic examinations were performed twice or more. We observed the ulcerous lesions of bronchial tuberculosis at various stages of healing, and could classify the ulcerous lesions into the following three stages. Active Stage: stage A; ulcer formation without regenerating epithelium, Healing Stage: stage H; ulcer formation with regenerating epithelium, Scarring Stage: stage S; and no ulcer formation. Only the lesions of stage A were observed before treatment. In many patients during the first and second month of treatment, the lesions were stage A or H. It was found that healing of the lesions of tracheobronchial tuberculosis progressed through the stages A, H, and S, in this order. The smear positive rates in sputum were 88.5% in stage A, 12.9% in stage H and 5.0% in stage S. The culture positive rates in sputum were 88.5% in stage A, 20.0% in stage H, and 0% in stage S. We conclude that at least 3 months were generally required for the healing of tracheobronchial tuberculosis with ulcerous lesion. However, it seems that the period of time for healing of ulcerous lesions is shorter in patients who are treated by aerosol therapy with SM.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The conducting airways, also commonly referred to as the upper airways, provide for the passage of air to and from the atmosphere and lungs. Anatomical components include the nasal passages, pharynx, larynx, trachea, and mainstem bronchi. Clinical problems involving the conducting airways can be manifested by relatively mild clinical signs of stertorous breathing, by life-threatening dyspnea, or by chronic bouts of inspiratory stridor and cough. Concurrent disease of the lower respiratory system (ie, chronic bronchitis) as well as other organ systems (ie, cardiovascular, nervous, endocrine) may significantly contribute to the etiology and pathophysiology of upper airway disease. Diagnosis of the diseases of the conducting airways is primarily based on history and physical examination. The dynamic nature of some conditions, related to the phases of respiration, can make diagnosis more difficult. In addition to direct visualization, radiographic and endoscopic evaluation are often useful. Many upper airway problems, especially congenital conditions, lend themselves to surgical palliation that should be performed as early in life as possible. Medical management is often directed at treating underlying diseases and the relief of clinical signs. Historically, the use of variety of drugs have been advocated and frequently include decongestants, cough suppressants, bronchodilators, glucocorticoids, and antibiotics. However, their use may be detrimental and contraindicated. In addition, therapy for some conditions (ie, laryngeal paralysis and intrathoracic tracheal collapse) may be better directed at increasing airway muscle tone in order to stabilized airway patency. Therapeutic agents that may be useful include aspirin and digitalis. The overall objective to medical management must be to balance potential therapeutic benefit against untoward effects in order to minimize clinical signs and to improve the animal's quality of life.

Abstract
The clinical features of tracheobronchial tuberculosis are distinct from those of pulmonary tuberculosis in some aspects. Streptomycin (SM) is claimed by some investigators that it has a tendency to promote the development of bronchial stenosis due to scarred healing of the involved endobronchial mucosa, and, for that reason, they recommend not to use it in treatment of bronchial tuberculosis. In some patients with pulmonary tuberculosis, who have renal or hearing disturbance, SM avoided. Yet unless SM is used improvement of tuberculosis could be delayed. It is the purpose of the present investigation to point out that aerosol therapy of SM is useful for patients with respiratory tuberculosis. Furthermore, we wish to demonstrate that we can safely treat the patients with respiratory tuberculosis who suffer from renal function or hearing disorder by use of aerosol therapy of SM. Prior to clinical application of the inhalation therapy, we confirmed that the therapy was not harmful. Serum concentration of SM, when inhaled, was measured in 9 volunteers. Before and after administration of SM aerosol, spirograms were examined in 4 volunteers, nevertheless, no special abnormality was recognized. It seemed that serum concentration of SM after the administration was two low to evoke adverse reactions (less than 3.0 gamma). In 6 patients with pulmonary tuberculosis, blood gases were measured and no obvious change was observed. As a result, it was demonstrated that the endobronchial tuberculous lesions improved faster when treated by inhalation of aerosolized SM as compared with the conventional injection therapy, without evoking any apparent adverse reactions. In some of the patients with pulmonary tuberculosis, it seemed that the therapy was useful.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Tracheal collapse, one form of tracheal obstruction, is classically described as occurring in middle-aged or older toy breed dogs with a history of chronic "goose-honk" cough. Many dogs with tracheal collapse fit this description, but others are young and may wheeze, hack, or have no cough at all. Patients with a history and physical examination compatible with tracheal collapse are definitively diagnosed based on the findings of the following respiratory tract examinations: inspiratory/expiratory radiographs, fluoroscopy, culture and susceptibility, and a thorough endoscopic evaluation. Prosthetic ring tracheoplasty relieves many of the signs of tracheal obstruction but does not cure the disease. Early diagnosis and treatment are expected to give the dog a better quality life. Following prosthetic ring tracheoplasty, most dogs are more active, breathe easier, cough less, and require less medical treatment for respiratory disease.

Abstract
Analysis was made of 20 patients with endobronchial tuberculosis proven by fiberoptic bronchoscopy and bronchial biopsy. Unlike prechemotherapy reports, the disease affects the older age group and more men. Only one half of the patients had fever, and the characteristic localized wheeze was found in 15 percent of cases. Chest roentgenogram showed typical collapse-consolidation in most cases; however, it was clear in 20 percent of patients. Sputum/smear was negative for AFB in 85 percent of patients. When the gelatinous granulation tissue was not found during bronchoscopy, a diagnosis of bronchogenic carcinoma was made incorrectly in 30 percent of patients. At a mean period of 27 months postchemotherapy, all 12 patients recalled for study developed bronchostenosis proven by bronchoscopy/bronchography except one. Noninvasive methods such as chest roentgenogram and flow-volume loops were insensitive for detection of stenosis. Steroid therapy probably did not influence outcome of tuberculous endobronchitis.

Abstract
Tracheal mucous velocity was measured in 13 healthy non-smokers using a radioisotope-labeled aerosol and a multidetector probe during respiratory virus infections. The movement of boluses of tracheal mucous were either absent or reduced in number in five subjects with myxovirus infection (four influenza and one respiratory syncytial virus) within 48 hr of the onset of symptoms and in four subjects 1 wk later. One subject with influenza still had reduced bolus formation 12-16 wk after infection. Frequent coughing was a feature of those subjects with absent tracheal boluses. In contrast, four subjects with rhinovirus infection had normal tracheal mucous velocity at 48 hr after the onset of symptoms (4.1 +/- 1.3 mm/min). Tracheal mucous velocity was also normal (4.6 +/- 1.1 mm/min) in four subjects in whom no specific viral agent could be defined but of respiratory viral infection. During health tracheal mucous velocity was (4.8 +/- 1.6 mm/min) in the eleven subjects who had measurements made. Disturbances in tracheal mucous transport during virus infection appear to depend upon the type of virus and are most severe in influenza A and respiratory syncytial virus infection.
