RESUMO
Introduction It is hypothesized that bronchoalveolar lavage (BAL) neutrophilia, Krebs von den Lungen-6 (KL-6), and C-reactive protein (CRP) predict the severity of chronic fibrosing interstitial lung diseases (CF-ILDs). Methods This cross-sectional study enrolled 30 CF-ILD patients. Using Pearson's correlation analysis, BAL neutrophils, KL-6, and CRP were correlated with forced vital capacity (FVC), diffusing lung capacity for carbon monoxide (DLCO), six-minute walk distance (6MWD), partial pressure of oxygen (PaO2), computed tomography fibrosis score (CTFS), and pulmonary artery systolic pressure (PASP). Using the receiver operator characteristic (ROC) curve, BAL KL-6 and CRP were evaluated against FVC% and DLCO% in isolation and combination with BAL neutrophilia for predicting the severity of CF-ILDs. Results BAL neutrophilia significantly correlated only with FVC% (r = -0.38, P = 0.04) and DLCO% (r = -0.43, P = 0.03). BAL KL-6 showed a good correlation with FVC% (r = -0.44, P < 0.05) and DLCO% (r = -0.50, P = 0.02), while BAL CRP poorly correlated with all parameters (r = 0.0-0.2). Subset analysis of BAL CRP in patients with CTFS ≤ 15 showed a better association with FVC% (r = -0.28, P = 0.05) and DLCO% (r = -0.36, P = 0.04). BAL KL-6 cut-off ≥ 72.32 U/ml and BAL CRP ≥ 14.55 mg/L predicted severe disease with area under the curve (AUC) values of 0.77 and 0.71, respectively. The combination of BAL neutrophilia, KL-6, and CRP predicted severity with an AUC value of 0.89. Conclusion The combination of BAL neutrophilia, KL-6, and CRP facilitates the severity stratification of CF-ILDs complementing existing severity parameters.
RESUMO
Tubercular empyema thoracis continues to be one of the leading causes of morbidity in low-income countries. Despite antitubercular therapy (ATT) and thoracostomy, empyema drainage is hampered by multiple septations, loculations, debris, and blood clots leading to complications. In a comparative experimental study to estimate the efficacy and safety of intrapleural streptokinase (IPSTK) in tubercular empyema, 30 cases of chronic multiloculated tubercular empyema were compared by radiological improvement by chest radiography, duration and volume of fluid drained, and degree of dyspnoea according to the modified Borg scale, depending on whether streptokinase was used or not. The former scored on all counts; we therefore conclude that intrapleural streptokinase is a safe, efficacious intervention in tubercular empyema. It decreases morbidity and reduces the need for surgery.

Background: Flexible bronchoscopy is an aerosol-generating procedure (AGP), which increases the risk of transmission of SARS-CoV-2 infection. We aimed to find COVID-19 symptoms among healthcare workers (HCWs) involved in flexible bronchoscopies for non-COVID-19 indications during the SARS-CoV-2 pandemic. Materials and Methods: The participants of this hospital-based single-center descriptive study were HCWs of our hospital involved in flexible bronchoscopies of patients with non-COVID-19 indications. These patients had no clinical features of COVID-19 and were tested negative for SARS-CoV-2 by the real-time polymerase chain reaction of nasopharyngeal and throat swabs before the procedure. The study outcome was the occurrence of COVID-19 in study participants after exposure to bronchoscopies. Results: Thirteen HCWs performed 81 bronchoscopies on 62 patients. Indications for bronchoscopies included malignancy (61.30%), suspected infections (19.35%), non-resolving pneumonia (6.45%), mucus plug removal (6.45%), central airway obstruction (4.84%), and hemoptysis (1.61%). The mean age of patients was 50.44 ± 15.00 years, and the majority was males (72.58%). Bronchoscopic procedures included 51 bronchoalveolar lavages, 32 endobronchial ultrasound- transbronchial needle aspiration (EBUS-TBNA), 26 endobronchial biopsies, 10 transbronchial lung biopsy (TBLB), 3 mucus plug removals, 2 conventional TBNA, and 2 radial EBUS-TBLB. Except for two HCWs who complained of transient throat irritation of non-infectious cause, none of the cases developed any clinical features suggestive of COVID-19. Conclusion: A dedicated bronchoscopy protocol helps in minimizing the risk of transmission of SARS-CoV-2 infection among HCWs involved in flexible bronchoscopies for non-COVID-19 indications during the SARS-CoV-2 pandemic.
RESUMO
Esophageal ultrasound-guided bronchoscopic needle aspiration (EUS-B-NA) is a relatively safe procedure with rare complications. A vasovagal attack after EUS-B-NA has not been reported to date. Usually benign and self-limiting, it can cause refractory bradycardia and sudden cardiac arrest. Timely intervention reduces morbidity and mortality. Here, we report a novel case of vasovagal attack after EUS-B-NA and was managed successfully. Management includes identifying the triggering event and keeping the patient in the Trendelenburg position. Atropine is reserved for refractory cases. (www.actabiomedica.it).

Disseminated Histoplasmosis, a systemic fungal infection caused by Histoplasma capsulatum is predominantly seen in immunocompromised cases. It is usually endemic, although sporadic cases have been reported. Following initial infection to the lungs, it disseminates to various organs by lymphatic and hematogenous routes. Clinical features are non-specific and depend on the extent and severity of organ involvement. A Biopsy is required for diagnosis and timely intervention decreases morbidity and mortality. Our case report describes an atypical association of progressive disseminated Histoplasmosis with bone marrow involvement in an immunocompetent adult from a non-endemic region and alerts the clinicians to a rare yet life-threatening mycosis.

RESUMO
BACKGROUND: The outbreak ofsevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has resulted inexponential rise in the number of patients getting hospitalised with corona virus disease 2019 (COVID-19). There is a paucity of data from South East Asian Region related to the predictors of clinical outcomes in these patients. This formed the basis of conducting our study. METHODS: This was an analytical cross-sectional study. Demographic, clinical, radiological and laboratory data of 125 patients was collected on admission. The study outcome was death or discharge after recovery. For univariate analysis, unpaired t-test, Chi-square and Fisher's Exact test were used. Receiver operating characteristic (ROC) curves were plotted for Sequential Organ Failure Assessment (SOFA) score and few laboratory parameters. Logistic regression was applied for multivariate analysis. RESULTS: Elderly age, ischemic heart disease and smoking were significantly associated with mortality. Elevated levels of D-dimer and lactate dehydrogenase (LDH) and reduced lymphocyte counts were the predictors of mortality. The ROCs for SOFA score curve showed a cut-off value ≥ 3.5 (sensitivity- 91.7% and specificity- 87.5%), for IL-6 the cut-off value was ≥ 37.9 (sensitivity- 96% and specificity- 78%) and for lymphocyte counts, a cut off was calculated to be less than and equal to 1.46 x 109per litre (sensitivity-75.2%and specificity- 83.3%). CONCLUSION: Old age, smoking history, ischemic heart disease and laboratory parameters including elevated D-dimer, raised LDH and low lymphocyte counts at baseline are associated with COVID-19 mortality. A higher SOFA score at admission is a poor prognosticator in COVID-19 patients.

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare idiopathic cystic interstitial granulomatous lung disease seen almost exclusively in cigarette smokers. It typically occurs between 20-40 years of age and equally distributed among both sexes. Management includes smoking cessation, avoidance of second-hand smoke, and close follow-up. Corticosteroids may be required in those with symptomatic disease with worsening lung function despite smoking cessation and progressive nodular stage of the disease. Here, we report an interesting case of biopsy-proven PLCH in a young never smoker female. Detailed questioning revealed significant exposure to incense smoke, highlighting a rare presentation of non-cigarette smoke-related PLCH. Avoidance of incense smoke combined with oral prednisolone (0.5mg/kg) tapered over 6 months led to complete resolution of symptoms, disappearance of nodules in high resolution computed tomography (HRCT) of the thorax and improvement in lung function.

Interstitial lung diseases (ILDs) are a frequently occurring pulmonary manifestation in patients of connective tissue diseases (CTD). Detailed understanding of this subset of lung diseases is vital, hence the study was conducted to analyze the clinico-radiological characteristics of CTD-ILD. The present study was conducted between March 2017 to February 2018 at a tertiary care teaching hospital from western India. A total of 100 patients having respiratory symptoms suggestive of ILD, who were either diagnosed cases of CTD or had clinical manifestations of underlying CTD, were included in the study. 27% of patients belonged to age group 41-50 years and 78% were females. Chief respiratory complaints were dyspnea and cough. Clubbing was present in 29% patients. The most common CTDs were rheumatoid arthritis [RA] (26%), systemic sclerosis [SSC] (21%), mixed connective tissue disorder [MCTD] (19%) and Sjogren's syndrome [SS] (16%). Restrictive defect on spirometry was seen in 58% cases and was most significant among patients with RA (65%) and SS (62%). Pulmonary arterial hypertension was seen in 40% cases and was most evident in MCTD (78%) and SSC patients (58%). Chest radiograph was normal in 47% of subjects. Most common radiological pattern on high resolution computed tomography (HRCT) thorax was non-specific interstitial pneumonia (42%) followed by usual interstitial pneumonia (21%). ILD is a common manifestation of CTD. Work-up for an underlying CTD should be offered to all ILD patients and vice versa.

BACKGROUND: Diagnosis and management of multidrug-resistant tuberculosis (MDR-TB) remains a global challenge and is associated with high morbidity and mortality. Burden of TB among symptomatic household contacts of MDR-TB is not extensively studied and screening of symptomatic contacts may provide a better opportunity for optimum management and effective TB control. METHODS: This prospective observational study was conducted in the department of Tuberculosis & Chest diseases, S.N. Medical College, Agra from February 2016 to January 2018. The study recruited 271 symptomatic household contacts of 87 index MDR-TB cases. Symptomatic contacts were screened for active disease and latent TB infection. Risk factors for the spread of disease were also looked for. RESULTS: Out of 271 symptomatic household contacts, 97 (35.79%) had active TB. Among 97 diseased, 62 (22.87%) had MDR-TB and 35 (12.91%) had drug-susceptible TB. 124 contacts (45%) had latent TB infection. Risk factors associated with occurrence of TB included age less than 18 years (OR = 7160, p = 0.1908, RR = 0.8082, p = 0.1887), male sex (OR = 2.3108, p = 0.0021, RR = 1.7444, p = 0.0034), Sibling as index case (OR = 0.6404, p = 0.0804, RR = 0.7520, p = 0.0806), lack of BCG vaccination (OR = 1.7763, p = 0.0271, RR = 1.4338, p = 0.0247) malnutrition (OR = 1.8980, p = 0.0138, RR = 1.5166, p = 0.0159) and lower socioeconomic status (OR = 3.2399, p < 0.0001, RR = 2.1524, p < 0.0001). CONCLUSION: The high case detection rate by screening symptomatic household contacts shows MDR-TB is highly transmissible and household contacts are at a higher risk of developing active disease. It provides an opportunity for early diagnosis, adequate treatment, and interrupt the chain of transmission. Identifying risk factors help prevent the progression of latent TB infection to active disease.

As no definitive therapy or vaccine is yet available for COVID-19, in a desperate attempt repurposed drugs are being explored as an option. A drug repurposing study identified Ciclesonide as a potential candidate. We reviewed the available evidence and clinical trials on the use of Ciclesonide in COVID-19. At present the evidence is limited to a report of three cases. However, five clinical trials are underway, and their results will help in elucidating the role of Ciclesonide in COVID-19.

Biphasic pulmonary blastoma (BPB) is an extremely rare highly aggressive malignant tumor that arises from fetal lung tissue and has the classical biphasic histology of epithelial and mesenchymal components. It is usually seen in adults with a slight male predominance and smokers. Previously grouped along with well-differentiated fetal adenocarcinoma (WDFA), and pleuropulmonary blastoma (PPB), now it is considered a separate variant and grouped under sarcomatoid neoplasms. Symptoms include chest pain, cough, hemoptysis and it is asymptomatic in at least one-third of the cases. A biopsy is essential for diagnosis and surgical excision is the treatment of choice. Prognosis is poor with 5-year survival less than 20% and recurrence occurring within 12 months of surgery. An aggressive multimodality approach is required for its management and active follow up surveillance is needed to look for recurrence.
