Background: Tobacco smoking has been recognized as the most important risk factor for chronic obstructive pulmonary disease (COPD) for a long time, but recent studies have shown that nonsmokers also contribute to a significant proportion of COPD. This study was performed to find out the proportion of nonsmoker individuals among COPD patients and to determine various etiologies in nonsmoker COPD patients. Materials and Methods: This study was an observational cross-sectional study conducted in Department of Pulmonary Medicine, MLN Medical College, Allahabad. A total of 200 COPD patients, aged >18 years of either gender with COPD, diagnosed by clinical and spirometric criteria (GOLD guideline) were included in the study. Results: Of the 200 COPD patients, the proportion of nonsmoker patients was 56.5%, and the smoker was 43.5%. Among 113 nonsmoker COPD patients, maximum number of patients (69.03%) belonged to low socioeconomic status but most important and statistically significant risk factor was exposure to biomass smoke (53.98%), other significant risk factors were treated pulmonary tuberculosis (32.74%), and long-standing asthma (14.16%). Risk factors that were not statistically significant were occupational exposure (9.73%), exposure to outdoor air pollution (3.54%), and lower respiratory tract infection during childhood (1.77%). The patients who were exposed to more than one risk factors, developed COPD at an earlier age. Conclusions: This study revealed that nonsmokers contribute a significant proportion of COPD patients. Multiple risk factors other than smoking also play a major role in the development of COPD, particularly exposure to biomass smoke, treated pulmonary tuberculosis, and long-standing asthma.

Background: Cotton industry workers are exposed to various hazards in the different departments of textile factories. The major health problems associated with cotton dust are respiratory problems, byssinosis, bronchitis and asthma. Objective: To study the effect of cotton dust exposure on pulmonary function and respiratory symptoms. Settings and Design: This cross-sectional observational study was conducted at cotton mill in the Ahmedabad city. Materials and Methods: One hundred cotton mill workers of the weaving and spinning area participated in this study while 100 age- and gender-matched male subjects living in the residential area served as the control group. A questionnaire was used to inquire about respiratory symptoms and spirometry was done in both the groups. Statistical Analysis Used: Student's t-test was used to find the difference between spirometric parameters, and Chi-square test was used to find the difference between respiratory symptoms. Results: Respiratory symptoms were statistically significantly more common in the cotton mill workers compared to control group. Cotton mill workers group also showed significant (P < 0.0001) decrease in forced expiratory volume in 1 s (FEV1), ratio of FEV1 and forced vital capacity (FVC) and peak expiratory flow rate, and no significant difference of FVC between groups. There was an association of duration of exposure and symptoms with spirometric abnormality. Conclusion: Cotton mill workers showed a significant decrease in spirometric parameters and increase in respiratory symptoms. As the duration of exposure and symptoms increased, spirometric abnormality increased.

Malignant pleural effusion (MPE) denotes an advanced malignant disease process. Most of the MPE are metastatic involvement of the pleura from primary malignancy at lung, breast, and other body sites apart from lymphomas. The diagnosis of MPE has been traditionally made on cytological examination of pleural fluid and/or histological examination of pleural biopsy tissue that still remains the initial approach in these cases. There has been tremendous advancement in the diagnosis of MPE now a day with techniques i.e. characteristic Ultrasound and computed tomography features, image guided biopsies, fluorodeoxyglucose-positron emission tomography imaging, thoracoscopy with direct biopsy under vision, tumor marker studies and immunocytochemical analysis etc., that have made possible an early diagnosis of MPE. The management of MPE still remains a challenge to pulmonologist and oncologist. Despite having various modalities with better tolerance such as pleurodesis and indwelling pleural catheters etc., for long-term control, all the management approaches remain palliative to improve the quality of life and reduce symptoms. While choosing an appropriate management intervention, one should consider the clinical status of the patient, life expectancy, overall cost, availability and comparative institutional outcomes, etc.

Aims and Objectives: Environmental pollens are known to cause exacerbation of symptoms of patients with allergic rhinitis (AR) and asthma. During pollen months, number of patients visiting hospital has been shown to increase in some studies. However, in India, such studies are lacking. Therefore, we aimed to study pollen counts and to find its correlation with number of new patients attending Asthma Bhawan for 2 years. Materialsx and Methods: Aerobiological sampling was done using Burkard 24 h spore trap system. The site selected for the entrapment of the air spore was the building of Asthma Bhawan situated at Vidhyadhar Nagar, Jaipur. New patients coming with problems of respiratory allergy such as AR or asthma were recruited in the study. Skin prick tests (SPTs) were carried out after obtaining consent in these patients. Monthly pollen counts of trees, weeds and grasses were correlated with the number of new patients. Pollen calendar was prepared for 2 years. Results: Average annual pollen count during 2011 and 2012 were 14,460.5. In the analysis, 37 types of species or families were identified. Pollen count showed two seasonal peaks during March–April and from August to October. January and June showed the lowest pollen counts in 2 years. Average monthly count of grass pollens showed significant correlation with number of new patients (r = 0.59). However, monthly pollen count of trees and weeds did not correlate. The correlation of the pollen count of individual pollen with the SPT positivity to that pollen showed significant correlation with Chenopodium album only. Conclusions: It can be concluded that there were two peaks of pollen count in a year during March–April and August–October. Average monthly pollen counts of grass were significantly correlated with the number of hospital visits of new patients.

Background: The prevalence of Aspergillus hypersensitivity (AH) and allergic bronchopulmonary aspergillosis (ABPA) has been variably reported. Systematic data regarding Aspergillus sensitization and ABPA are lacking from this part of the country. Objectives: The aim of this study was to evaluate the prevalence of AH and ABPA in Uttar Pradesh. Setting and Design: This was prospective observational study. All patients attending outpatient Department of Pulmonary Medicine of our institute were included in the study. Subjects and Methods: Consecutive asthmatic patients underwent screening for ABPA using Aspergillus skin test (AST). Those showing a positive response to AST were further evaluated for ABPA. Results: During the study, 350 patients (192 males, 158 females, mean ± standard deviation age: 38.3 ± 12.8) were screened with AST. One hundred and twenty-three patients (35.1%) were tested positive for AST and 21.7% of patients were diagnosed as ABPA. Conclusions: A high prevalence rate of ABPA was observed at our chest clinic. Although comparable with published data from other tertiary centers, it does not represent the true prevalence rates in asthmatics because of high chances of referral bias.

Background and Objective: To evaluate the utility of fractional exhaled nitric oxide (FeNO) in monitoring asthma control. Materials and Methods: Steroid naïve nonsmoking asthmatics were recruited and followed for 6–8 weeks on standard treatment. Serial measurements of FeNO, peak expiratory flow rate (PEFR) variability, forced expiratory volume in 1 s (FEV1), bronchodilator reversibility (BDR), and asthma control test (ACT) score were measured at baseline and after 6–8 weeks of treatment. Results: One hundred and fifty-one patients were recruited over an 18-month period. These comprised 79 males (52.3%) with mean (standard deviation) age of 34.2 (11.6). Mean (SD) FeNO levels at baseline and after therapy were 45.4 (35.9) and 38.4 (23.7) ppb, respectively (P = 0.01). Baseline FeNO correlated strongly with FEV1 (r = −0.78, P < 0.001), ACT score (r = −0.76, P < 0.001), PEFR variability (r = −0.74, P < 0.001), and moderately with BDR (r = 0.50, P < 0.001). After treatment with inhaled steroids, the correlation remained strong with ACT score (r = −0.68, P < 0.001) but weakened with PEFR variability (r = −0.34, P = 0.01) and FEV1 (r = −0.36, P = 0.01). Conclusions: FeNO may be useful as an adjunctive noninvasive modality to assess asthma control in both steroid naïve asthmatics and asthmatics on treatment. However, the suboptimal sensitivity and specificity may limit its utility as a point-of-care single monitoring tool.

Background: Chronic obstructive pulmonary disease (COPD) attribute to systemic inflammation which is responsible for microalbuminuria reflecting endothelial dysfunction, could be a significant surrogate marker of potential cardiovascular morbidity. Objective: The aim of our study was to find out the possible association of COPD with early cardiovascular changes in the form of renal endothelial dysfunction. Settings and Design: Case–control, multi-group, cross-sectional hospital-based study was designed and conducted in the Department of Respiratory Medicine of BPS Government Medical College for Women, Khanpur Kalan, Sonipat, Haryana. Subjects and Methods: The study included 150 subjects, comprising of three groups with each having 50 subjects: Group 1 – acute exacerbation of COPD, Group 2 – stable COPD patients, Group 3 – asymptomatic smokers. Pulmonary function test, urine albumin creatinine ratio (UACR) and brachio-ankle pulse wave velocity were measured in all the subjects. Statistical Analysis: Data were analyzed using SPSS ver 20 (IBM, USA) software. Continuous variables were compared by unpaired Student's t-test while correlation was measured by Pearson correlation test, P < 0.05 was considered statistically significant. Results: The mean urine albumin creatinine ratio UACR value in acute exacerbation of COPD (283.30 mg/g; standard deviation [SD] ±871.98) was found significantly higher compare to control subjects (24.17 mg/g; SD ± 32.105;) P = 0.038. Besides this COPD patients with Type 2 respiratory failure having robust positive correlation in between UACR and arterial blood pH (r = 0.559; P = 0.030) while it was inverse and moderate with partial pressure of arterial oxygen (r = −0.470; P = 0.077). Conclusions: Acute state of COPD with or without Type 2 respiratory failure is having a significant impact on cardiovascular system in the form of early microvascular changes.

Central airway obstruction (CAO) can result from various benign and malignant etiologies. Anaplastic thyroid cancer (ATC) is the most aggressive form of thyroid cancer. Rapid airway compromise is the main cause of death in ATC. We report a patient with ATC who presented with a large neck mass leading to CAO with long segment tracheal and right main bronchial compression and respiratory failure. Urgent Rigid Bronchoscopy was performed for airway stabilization and patient was managed with a combination airway stenting approach. A combination of self expanding, metallic, covered inverted Y and straight tracheal stents was used to stabilize the near complete airway structure. We herein highlight the role of therapeutic rigid bronchoscopy with airway stenting as an efficacious treatment modality for management of malignant CAO.

Background: Tuberculosis (TB), a highly contagious disease that sees no gender, age, or race is mainly a disease of lungs. According to World Health Organization, a TB patient can be completely cured with 6–9 months of anti-TB treatment under directly observed treatment short course. Objectives: The aim of this study was to check the mono, multi- and triple-drug resistance to first line drugs (FLDs) among TB patients and to access their genetic profile using DR 3074, DR 0270, DR 0642, DR 2068, and DR 4110 using molecular techniques. Material and Methods: To gain a better understanding of drug resistant TB, we characterized 121 clinical isolates recovered from 159 drug resistant pulmonary tuberculosis patients by IS6110 genotyping. MTB isolates recovered from HIV- negative, and smear positive cases of both genders, age varied from 18 to 70 years with drug resistant-TB that was refractory to chemotherapy given for > 12 months. Of a total of 159 sputum smear positive patients sum number of male and female patients was 121 (76.10%) and 38 (23.89%), respectively. Among these patients, number of literate and illiterate patients were 123 (77.3%) and 36 (22.6%). 25 (15.7%) patients had farming as their occupation, 80 (50.3%) had nonagricultural occupation and 54 (33.9%) women were housewives. Results: Mono drug resistant, multi-drug resistant, and totally drug resistant (TDR) cases of TB were calculated as 113.83%, 125.1%, and 67.9%. Isoniazid showed the highest percentage of resistance among the patients. Conclusion: Any noncompliance to TB medications, lack of knowledge, and poor management in health centers, etc., results in the emergence of deadly direct repeat forms of TB, which are further complicated and complex to treat.

Pulmonary mucormycosis is an opportunistic fungal infection in immunocompromised individuals. It is difficult to diagnose as it requires tissue biopsy, and generally these patients are unfit to undergo invasive lung biopsies. We describe a novel technique in a case with uncontrolled diabetes mellitus with nonresolving pulmonary cavitary disease where convex probe endobronchial ultrasound (EBUS)-guided aspiration of lung cavity wall showed classical histopathological picture establishing the diagnosis of mucorale infection. EBUS being real-time, minimally invasive technique with minimal risk of complications, led to early diagnosis, and prompt treatment. This appears to be a novel diagnostic modality in pulmonary mucormycosis with minimal complications as compared with other biopsy methods with very high complication risk.

Actinomycosis is an indolent, slowly progressive infection caused by anaerobic or microaerophilic bacteria, primarily from the genus Actinomyces. Thoracic involvement is observed in approximately 15% of cases of infection with actinomycosis. Here, we present a case of a 61-year-old male who presented with recurrent endobronchial actinomycosis. The case is being presented because of its rarity on three counts – endobronchial involvement, which is uncommon, recurrence in different sites in the bronchial tree, which is even rarer and development of the disease following an endobronchial procedure.

Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis. Surprisingly, transthoracic biopsy and histopathology revealed metastasis from follicular carcinoma of thyroid. This prompted us for a retrograde evaluation for a primary thyroid malignancy for which an ultrasound and contrast enhanced computed tomography (CECT) of the neck was done which confirmed the presence of a solitary thyroid nodule. Ultrasonography-guided fine-needle aspiration cytology of the nodule revealed follicular carcinoma of thyroid. Histopathological evaluation subsequent to total thyroidectomy revealed follicular carcinoma thyroid, further confirming the diagnosis. The patient was then referred to Department of Nuclear Medicine and Radiotherapy for radionuclide ablation and chemotherapy. We chose to report this case because of its rare presentation as a large intrathoracic mass and the retrograde diagnosis of follicular carcinoma of thyroid. To the best of our knowledge, this is the first report of such a rare case.
