ABSTRACT
We present a case diagnosed with hepatosplenic sarcoidosis with hypercalcemia. Elevated liver enzymes and hypercalcemia were detected in the patient who was admitted to the hospital with abdominal pain and dyspnea. Abdominal dynamic magnetic resonance imaging (MRI) showed diffuse, multiple, nodular hyperintense lesions on T2 weighted. Multinuclear giant cells and lymphocytic portal inflammation were seen in the patient's liver biopsy, whose angiotensin-converting enzyme level was high, and hepatosplenic sarcoidosis was diagnosed. Shortness of breath, abdominal pain, and calcium level improved with methylprednisolone treatment.
ABSTRACT
Purpose: GOLD 2019 proposed a novel treatment decision tool for follow-up based on the predominant trait (exacerbation or dyspnea) of patients, alongside treatment escalation and de-escalation strategies. This study was designed to provide an up-to-date snapshot of patient and disease characteristics, treatment pathways, and healthcare resource use (HRU) in COPD in real life, and comprehensively examine patients considering GOLD 2019 recommendations. Patients and Methods: This mixed design, observational, multicenter (14 pulmonology clinics) study included all patients with a documented COPD diagnosis (excluding asthma-COPD overlap [ACO]) for ≥12 months, aged ≥40 years at diagnosis who had a COPD-related hospital visit, spirometry test and blood eosinophil count (BEC) measurement under stable conditions within the 12 months before enrollment between February and December 2020. Data were collected cross-sectionally from patients and retrospectively from hospital medical records. Results: This study included 522 patients (GOLD group A: 17.2%, B: 46.4%, C: 3.3%, D: 33.1%), of whom 79.5% were highly symptomatic and 36.2% had high risk of exacerbation. Exacerbations (n = 832; 46.6% moderate, 25.5% severe) were experienced by 57.5% of patients in the previous 12 months. Inter-rater agreement between investigators and patients regarding the reason for visit was low (κ coefficient: 0.338, p = 0.001). Inhaled treatment was modified in 88 patients at index, mainly due to symptomatic state (31.8%) and exacerbations (27.3%); treatment was escalated (57.9%, mainly switched to LABA+LAMA+ICS), inhaler device and/or active ingredient was changed (36.4%) or treatment was de-escalated (5.7%). 27% had ≥1 hospital overnight stay over 12 months. Emergency department visits and days with limitation of daily activities were higher in group D (p < 0.001). Conclusion: Despite being on-treatment, many patients with COPD experience persistent symptoms and exacerbations requiring hospital-related HRU. A treatable trait approach and holistic disease management may improve outcomes by deciding the right treatment for the right patient at the right time.

This study was conducted with randomized controlled and experimental design to examine the effect of breathing exercise on daytime sleepiness and fatigue on patients with obstructive sleep apnea syndrome. The first application was performed by teaching patients in the intervention group breathing exercises including diaphragmatic and pursed lip breathing via the face-to-face interview technique. Then, the researcher applied breathing exercises in the same patient group every morning/evening for 10-15 min and a total of 20-30 min for eight weeks via the online interview method. The data were collected via a questionnaire, Epworth sleepiness scale (ESS), and Piper Fatigue Scale (PFS). Chi-square, Student's t, Mann Whitney U, paired sample t-test, analysis of variance (ANOVA) and generalized estimating equations were used to assess the data. It was determined that PFS total mean score of the intervention group which was 6.15 ± 1.65 before the application decreased to 5.34 ± 1.94 in the eighth week (p> 0.05) and PFS total mean score of the control group which was 5.59 ± 1.76 before the application increased to 5.77 ± 1.81 in the eighth week (p> 0.05). ESS total mean score of the intervention group which was 12.13 ± 4.34 at the baseline decreased to 9.13 ± 4.71 in the eighth week (p> 0.05) and ESS total mean score of the control group which was 10.37 ± 2.77 at the baseline increased to 10.5 ± 2.85 in the eighth week (p> 0.05). It was concluded that breathing exercise performed in the intervention group decreased the fatigue and daytime sleepiness mean scores of the patients at the end of the fourth and eighth week. In addition, the group-time interaction was significant, which was associated with the intervention group.

Introduction: The aim of our study is to investigate the etiological distribution of ILD in Turkey by stratifying the epidemiological characteristics of ILD cases, and the direct cost of initial diagnosis of the diagnosed patients. Material-Method: The study was conducted as a multicenter, prospective, cross-sectional, clinical observation study. Patients over the age of 18 and who accepted to participate to the study were included and evaluated as considered to be ILD. The findings of diagnosis, examination and treatment carried out by the centers in accordance with routine diagnostic procedures were recorded observationally. Results: In total,1070 patients were included in this study. 567 (53%) of the patients were male and 503 (47%) were female. The most frequently diagnosed disease was IPF (30.5%). Dyspnea (75.9%) was the highest incidence among the presenting symptoms. Physical examination found bibasilar inspiratory crackles in 56.2 % and radiological findings included reticular opacities and interlobular septal thickenings in 55.9 % of the cases. It was observed that clinical and radiological findings were used most frequently (74.9%) as a diagnostic tool. While the most common treatment approaches were the use of systemic steroids and antifibrotic drugs with a rate of 30.7% and 85.6%, respectively. The total median cost from the patient's admission to diagnosis was 540 Turkish Lira. Conclusion: We believe that our findings compared with data from other countries will be useful in showing the current situation of ILD in our country to discuss this problem and making plans for a solution.
ABSTRACT
We investigated whether the difference of antigen tube 2 (TB2) minus antigen tube 1 (TB1) (TB2-TB1) of the QuantiFERON-TB gold plus test, which has been postulated as a surrogate for the CD8+ T-cell response, could be useful in identifying recent tuberculosis (TB) exposure. We looked at the interferon gamma (IFN-γ) responses and differences in TB2 and TB1 tubes for 686 adults with QFT-plus positive test results. These results were compared among groups with high (368 TB contacts), low (229 patients with immune-mediated inflammatory diseases [IMID]), and indeterminate (89 asylum seekers or people from abroad [ASPFA]) risks of recent TB exposure. A TB2-TB1 value >0.6 IU·ml-1 was deemed to indicate a true difference between tubes. In the whole cohort, 13.6%, 10.9%, and 11.2% of cases had a TB2>TB1 result in the contact, IMID, and ASPFA groups, respectively (P = 0.591). The adjusted odds ratios (aORs) for an association between a TB2-TB1 result of >0.6 IU·ml-1 and risk of recent exposure versus contacts were 0.71 (95% confidence interval [CI], 0.31 to 1.61) for the IMID group and 0.86 (95% CI, 0.49 to 1.52) for the ASPFA group. In TB contact subgroups, 11.4%, 15.4%, and 17.7% with close, frequent, and sporadic contact had a TB2>TB1 result (P = 0.362). The aORs versus the close subgroup were 1.29 (95% CI, 0.63 to 2.62) for the frequent subgroup and 1.55 (95% CI, 0.67 to 3.60) for the sporadic subgroup. A TB2-TB1 difference of >0.6 IU·ml-1 was not associated with increased risk of recent TB exposure, which puts into question the clinical potential as a proxy marker for recently acquired TB infection. IMPORTANCE Contact tuberculosis tracing is essential to identify recently infected people, who therefore merit preventive treatment. However, there are no diagnostic tests that can determine whether the infection is a result of a recent exposure or not. It has been suggested that by using the QuantiFERON-TB gold plus, an interferon gamma (IFN-γ) release assay, a difference in IFN-γ production between the two antigen tubes (TB2 minus TB1) of >0.6 IU·ml-1 could serve as a proxy marker for recent infection. In this large multinational study, infected individuals could not be classified according to the risk of recent exposure based on differences in IFN-γ in TB1 and TB2 tubes that were higher than 0.6 IU·ml-1. QuantiFERON-TB gold plus is not able to distinguish between recent and remotely acquired tuberculosis infection, and it should not be used for that purpose in contact tuberculosis tracing.

INTRODUCTION: Hereditary angioedema (HAE) may be fatal and diagnosis can be delayed up to 10 years. We aimed to screen HAE in two villages based on an index case of HAE and to investigate for the mutation of the C1 esterase inhibitor (C1-INH) gene. MATERIAL AND METHODS: A total of 124 people were screened in two villages. The frequency and severity of symptoms were scored. C4, C1-INH levels and C1-INH activity were measured. We investigated for mutations of the C1-INH gene. RESULTS: Thirty-five cases of type I HAE and 7 cases of type II HAE were determined. Thirty-one (73.8%) patients diagnosed with HAE were 18 years old or younger. There was a positive correlation between C4 levels, C1-INH levels (p < 0.0001, r = 0.81), and C1-INH activity levels (p < 0.0001, r = 0.631) and between the age at diagnosis and severity score (p < 0.0001, r = 0.651). A positive correlation was found between the age at first symptom onset and C4 levels (p = 0.002, r = 0.774), and C1-INH levels (p = 0.006, r = 0.714). A marginally significant negative correlation was found between C1-INH activity levels and severity scores (p = 0.1, r = -0.515). We identified a novel heterozygous 1033G>T missense variant of the C1-INH gene, SERPING1, in patients with type I HAE. CONCLUSIONS: There are long delay periods in the diagnosis of HAE and when the index case is present, family screening may be very important and even life-saving, in particular, in paediatric patients without symptoms. Furthermore, the present study provides evidence to link a novel mutation, c.1033G>T, to the development of HAE in a large HAE family from Turkey.
ABSTRACT
BACKGROUND: Hereditary angioedema (HAE) is characterised by recurrent episodes of angioedema and can be fatal. OBJECTIVE: The present study aimed to screen HAE. METHODS: A total of 60 individuals were screened. The frequency and severity of symptoms were scored from 0 to 8. Measurements were taken of C4 and C1 esterase inhibitor protein (C1-INH) levels. Mutation in the C1 inhibitor gene was examined in 9 patients with HAE. RESULTS: A positive correlation between the C1 esterase inhibitor protein levels and C4 level was detected in the group as a whole (p < 0.001, r = 0.725, n = 60). Anegative correlation between the C1 esterase inhibitor protein level and severity score was observed in the whole group (p < 0.001, r = -0.486, n = 60). A negative correlation was also detected in the entire group between the C4 level and severity score (p = 0.002, r = -0.389, n = 60). In the patients with HAE, a positive correlation between the C1 esterase inhibitor protein level and C4 levels was detected (p = 0.034, r = 0.705, n = 9). A heterozygous c. 601A > T nonsense variant was identified at the C1 esterase inhibitor gene-SERPING1-in patients with Type 1 HAE. CONCLUSION: It is well known that there is a prolonged delay in the diagnosis of HAE. The present study demonstrates that it is very important and even life-saving to screen for HAE on the basis of an index case.

PURPOSE: The purpose of this study was to investigate the prevalence of obstructive sleep apnea (OSA) in patients with hemoptysis. METHODS: Files of patients who had undergone bronchial arterial embolization due to hemoptysis between 1 December 2009 and 2015 were evaluated and interviews of patients were conducted until 1 June 2016. Pittsburgh Sleep Quality Index (PSQI), STOP and STOP-BANG surveys were administered. OSA risk was determined with Berlin Questionnaire. RESULTS: Study group consisted of 53 patients and 58 control subjects. Mean age was 46.94 ± 14.36 and 41.97 ± 12.92 in patient and control group, respectively. Of these patients, seven had re-embolization procedure because of recurrence of hemoptysis. High OSA risk was more common among patients with hemoptysis (24.5%, n = 13) than the control group (8.6%, n = 5) (p = 0.023). Percentage of high risk OSA patients with massive hemoptysis, nonmassive hemoptysis, and control subjects was 29.7% (n = 11), 12.5% (n = 2), and 8.6% (n = 5), respectively (p = 0.022). There were more high OSA risk subjects among patients with idiopathic hemoptysis 44.4% (four out of nine), while 20.5% (nine out of 53) patients with a known etiology had high risk (p = 0.127). The number of patients with high OSA risk was also higher in patients who required a second embolization procedure (four out of seven, 57.1%), while 19.6% of patients without need for re-embolization had high risk (p = 0.031). CONCLUSIONS: OSA is found to be a risk factor for hemoptysis and also may provoke massive hemoptysis. It seems reasonable to consider OSA as an underlying condition in idiopathic hemoptysis. OSA may contribute to embolization failure.

Management of cryptogenic massive hemoptysis is difficult, and conservative treatment may be inadequate to stop the hemorrhage. Surgery is not a reasonable option because there is no underlying identifiable pathology. This study aimed to investigate the radiologic findings and bronchial artery embolization outcomes in cryptogenic hemoptysis, and to compare the results with non-cryptogenic hemoptysis. We evaluated 26 patients with cryptogenic hemoptysis and 152 patients with non-cryptogenic hemoptysis. A comparison of the bronchial artery abnormalities between the cryptogenic and non-cryptogenic hemoptysis groups showed that only extravasation was more statistically significant in the cryptogenic hemoptysis group than in the non-cryptogenic hemoptysis group, while the other bronchial artery abnormalities, such as bronchial artery dilatation, hypervascularity, and bronchial-to-pulmonary shunting, showed no significant difference between groups. Involvement of the non-bronchial systemic artery was significantly greater in the non-cryptogenic hemoptysis group than in the cryptogenic hemoptysis group. While 69.2% of patients with cryptogenic hemoptysis also had hypervascularity in the contralateral bronchial arteries and/or ipsilateral bronchial artery branches other than the bleeding lobar branches, this finding was not detected in non-cryptogenic hemoptysis. Embolization was performed on all patients using polyvinyl alcohol particles of 355-500 µm. Hemoptysis ceased in all patients immediately after embolization. While recurrence of hemoptysis showed no statistically significant difference between the cryptogenic and non-cryptogenic hemoptysis groups, it was mild in cryptogenic hemoptysis in contrast to mostly severe in non-cryptogenic hemoptysis. Transarterial embolization is a safe and effective technique to manage cryptogenic hemoptysis.

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea (OSA) is common in adult population and may cause many adverse clinical results. We aimed to investigate possible changes in cardiopulmonary exercise capacity in OSA patients after positive airway pressure treatment. DESIGN AND SETTINGS: Patients who were admitted to Gaziantep University Pulmonary Diseases Sleep Center and diagnosed OSA were included. Studies carried out between May 2010 and July 2011. Sixty-five consecutive patients were included in this prospective study. PATIENTS AND METHODS: Sixty-five adult sleep clinic patients diagnosed with OSA by polysomnography and in whom continuous positive airway pressure (CPAP) ventilation therapy was indicated were included. Cardiopulmonary exercise capacity was assessed by bicycle ergometry during diagnostic workup and at least 4 weeks later. RESULTS: There were 57 (87.7%) males. The mean age was 45.29 (10.57) years, apnea-hypopnea index 38.02 (23.19 events/h, body mass index 31.72 (4.87) kg/m2. Patients were grouped with respect to compliance with CPAP. The peak oxygen consumption (VO2) did not change in the CPAP compliant group (n=33) (22.52 [6.62] mL/[min.kg] to 21.32 [5.26] mL/[min.kg]; P=.111), and decreased from 21.31 (5.66) mL/(min.kg) to 19.92 (5.40) mL/(min.kg) (P=.05) in the CPAP noncompliant group. Work rate increased from 84.0% to 85.0% in the CPAP compliant group and decreased from 79.6% to 77.1% in the noncompliant group (P=.041). In the group that used the device, ventilation (VE)/VCO2 at anaerobic threshold (AT) declined from 28.42 to 27.36; however, it increased from 27.41 to 27.81 in the group that did not use the device (P=.033). CONCLUSIONS: Decline in the exercise capacity was prevented in patients with OSA after 4 weeks of CPAP therapy. The changes in VE/VCO2 at AT suggest the reversal of pathophysiologic changes in OSA with the CPAP therapy that may improve cardiac function and cause more efficient ventilation.

PURPOSE: Obstructive sleep apnea (OSA) syndrome causes systemic consequences due to hypoxia and endothelial dysfunction. The purpose of this study was to investigate whether OSA is more common in subjects with pulmonary embolism (PE). METHODS: This prospective study was conducted between November 2009 and December 2010 in the Department of Pulmonary Medicine of Gaziantep University. Twenty-eight patients with PE were included in the study group along with forty-five subjects with OSA as the control group. The control group was selected from among subjects who were referred to the sleep clinic. Full night polysomnography was performed for each subject. RESULTS: Mean apnea-hypopnea index (AHI) was found to be higher in the PE group compared with the control group (p=0.010). Severe OSA was detected in 21.4% of the PE group but in no controls (p=0.015). Sleep stage 2 was longer in control group whereas stage 1 and rapid eye movement (REM) sleep was longer in the PE group. Snoring and excessive daytime sleepiness were more common in the control group compared with the study group. AHI severity and thrombus localization were not significantly different between the groups (p=0.350). CONCLUSION: Our study findings suggest that OSA is more prevalent and severe in subjects with PE compared with control subjects. The clinical significance of less prevalent excessive daytime sleepiness and snoring in subjects with PE should be evaluated in further studies.

INTRODUCTION: Positive pressure ventilation is considered first line therapy in obstructive sleep apnea syndrome however compliance is limited by various factors. We aimed to investigate possible factors influencing compliance. MATERIALS AND METHODS: One hundred and forty patients were prescribed positive pressure ventilation for obstructive sleep apnea during June 2006-June 2008. Of these patients, 77% (n= 108) were reached by telephone and a questionnaire was administered regarding factors influencing treatment compliance. Airway passage was measured with C2 vertebrae level and narrowest airway passage on lateral skull radiographs. RESULTS: The mean age was 52.2 ± 12.3 years. Seventy one percent (n= 77) of subjects obtained the prescribed device. There was no difference in sex, age, marital status, educational level, symptoms, co-morbid conditions, and social security coverage between the subjects who have received the prescribed devices and who have not (p> 0.05). No difference was detected between these two groups of patients in view of Epworth sleepiness scale (ESS) and apnea hypopnea index (AHI). Mean duration of device usage was 6.3 ± 2.3 hours. The device use compliance was not affected by any of the following factors: age, gender, level of education, co-morbid diseases, ESS score, AHI, airway passage measurements, application of humidification and education concerning the device (p> 0.05). Patient (p= 0.057) and bed partners (p= 0.001) satisfaction about the device yielded higher compliance rates. CONCLUSION: Factors influencing compliance rates in obstructive sleep apnea syndrome seems to be related to satisfaction about the device use however upper airway morphology measured with C2 vertebrae level and narrowest airway passage has no impact on treatment compliance.

OBJECTIVES: Psychiatric disorders are common in obstructive sleep apnea syndrome (OSAS); however, interrelating factors influencing psychiatric comorbidity (PC) in OSAS are unclear. The aim of this study is to investigate gender related differences with PC in OSAS. METHODS: Data of patients diagnosed as OSAS in University of Gaziantep from January 2006 to January 2010 were retrospectively evaluated. Polysomnographic data were recorded with Viasys Sleep Screen (Viasys Healthcare, Germany). Patients younger than 18 years old were excluded. RESULTS: PC was present in 53.1% of OSAS patients. The rate of male subjects with PC was 42.6%; however, 76.26% of females had PC (P = 0.00). Age (P = 0.00) and body mass index (BMI) (P = 0.00) were higher in patients with PC. Ferritin levels were lower in patients with PC (P = 0.00). Male subjects with PC were older and had lower sleep efficiency and longer rapid eye movement latency than males without PC. BMI was the only contributory factor to PC in female subjects. CONCLUSION: PC in OSAS is common, especially in females. Apnea hypopnea index does not seem to influence probability of PC.

There is currently no national data on the effects of polyvinyl chloride (PVC) exposure on pulmonary function. In this study we recruited workers and administrative staff from two PVC plants between July 2008 and July 2009. A questionnaire, pulmonary function tests, carbon monoxide diffusion capacity, and peak flows were recorded. Particulate matter analyses were performed by the Adana Central Laboratory of the Directorate of Occupational Health and Safety. Data were analyzed with SPSS 13.0 software. Nine of the 147 subjects were female. The incidence of a cough was more common in the administrative group. Of the study population, 59.1% were smokers. Tobacco addiction significantly increased cough and dyspnea [OR= 1.10 (1.00-1.20, 95% CI) p= 0.007 and OR= 1.08 (1.02-1.14, 95% CI), p= 0.008, respectively]. Dust exposure was correlated with the incidence of a cough [OR= 0.20 (0.04-0.80, 95% CI) p= 0.008]. The period of work correlated with sputum production [OR= 1.00 (1.00-1.02, 95% CI) p= 0.044]. The FVC% was significantly higher in the administrative group, and FEV1/FVC and DLCO were higher in the exposed group. Tobacco addiction increased the risk of airflow limitation, as evaluated by FEV1/FVC < 70% and FEF25-75 < 50% [OR= 1.15 (1.06-1.25, 95% CI) p= 0.001 and OR= 1.09 (1.02-1.17, 95% CI) p= 0.010, respectively]. Tobacco addiction and increasing duration of work had a negative influence on DLCO in the exposed group (r= -0.270, p= 0.025 and r= -0.210, p= 0.037). In the exposed group PEF variability was significantly greater on workdays, compared with rest days. This study shows that tobacco consumption has a greater affect on the airways than PVC dust exposure. A median of 36 months exposure to PVC dust had no significant impact on pulmonary function parameters, except for DLCO and PEF variability.

In this study, we aimed to evaluate the performance of transbronchial needle aspiration (TBNA) combined with positron emission tomography/computed tomography (PET/CT) for the staging of lung cancer. Twenty-five patients having lymphadenopathies greater than 1 cm on thorax CT and maximum standardized uptake value (SUVmax) ≥ 2.5 on PET/CT were included in this prospective study performed between March 2006 and March 2008. Forty-three lymphnode stations were sampled by using TBNA. Surgical histology, as confirmed by mediastinoscopy, was accepted as the "gold standard". The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of combined TBNA and PET/CT for correct lymph node staging were 67%, 100%, 100%, 76% and 84%; respectively. The initial clinical staging was downstaged after TBNA in 13/19 (69%) patients with adequate TBNA samples, whereas staging was correct in 17/19 (89%) patients assessed by combined TBNA and PET/CT. Staging was completed by TBNA, without mediastinoscopy, in 6/25 (24%) patients. Among the clinical factors that were assessed, only the PET SUVmax was associated with positive TBNA results [odds ratio (OR) 1.27, 95% CI 1.004-1.61, p= 0.046]. A PET SUVmax ≥ 5 was eleven times more likely in patients with positive TBNA results [OR 10.68, 95% CI 1.91-59.62, p< 0.01]. In conclusion, the combination of TBNA with PET/CT increased the sensitivity of TBNA. Combined TBNA and PET/CT may also allow adequate mediastinal staging of lung cancer in most patients with enlarged lymph nodes, and reduce the need for mediastinoscopy. The SUVmax cut off point for a positive TBNA result was ≥ 5.

Diffuse alveolar haemorrhage (DAH) is indicated by the presence of red blood cells, fibrin and haemosiderin deposits in the lung parenchyma. We present a case of DAH in a 25-year-old male following 5-nitroimidazole treatment. The first episode of haemoptysis occurred following metronidazole treatment 10 months previously. The second episode of haemoptysis occurred following ornidazole treatment 10 days before admission. During his first admission, the patients haemoglobin concentration decreased to 40 g/L. The CXR was normal, whereas high resolution CT of the lungs revealed a diffuse acinonodular pattern. Serological tests for connective tissue diseases were negative. The haemorrhagic appearance of the BAL fluid obtained during fibreoptic bronchoscopy was consistent with DAH. Microbiological analysis of the BAL fluid showed no evidence for bacterial or mycobacterial infection. Haemosiderin laden macrophages were detected in BAL fluid and lung biopsy specimens. DAH due to use of 5-nitroimidazole was diagnosed on the basis of the patient's previous history and complete recovery following treatment with corticosteroid. This is the first reported case of DAH due to use of 5-nitroimidazole. Physicians should be aware of this side-effect when prescribing this group of drugs to patients.

UNLABELLED: To investigate the effectiveness oftoluidine blue-stained wet films in preliminary cytologic evaluation of bronchial washings. STUDY DESIGN: Bronchial washings were obtained by flexible fiberoptic bronchoscopy from 179 patients with suspected bronchial carcinoma. Each sample was evaluated with toluidine blue-stained wet films as benign, suspicious or malignant, and the diagnoses were compared to results of conventional smears and cell blocks. The sensitivity, specificity, positive predictive value and negative predictive value of wet films were determined. RESULTS: Of 179 samples, toluidine blue stains from 18 samples were classified as malignant, 4 samples as suspicious and 157 samples as benign. The sensitivity of the wet films was 83.3%, specificity was 98.7%, positive predictive value was 90.9% and negative predictive value was 97.5%. CONCLUSION: Initial cytologic evaluation of bronchial washings with toluidine blue-stained wet films is simple, fast and inexpensive. Moreover, it provides guidance for additional procedures for the definitive diagnosis.
