Evaluation of delays during diagnosis and management of lung cancer in India: A prospective observational study.

OBJECTIVE: The majority of lung cancers are diagnosed at an advanced stage; the reasons for which are variable and unclear. METHODS: Lung cancer patients were evaluated prospectively to quantify various timelines and establish reasons for delays. Timelines were defined as time intervals between symptom onset, first physician visit, first specialist visit, date of diagnosis and treatment. RESULTS: A total 410 patients were included, majority having advanced disease. The median period for a first visit to a physician was 30 days (interquartile range [IQR] 20-90), 50 days (IQR 20-110) for referral to our centre, 23 days (IQR 14-33) to reach diagnosis, and 24 days (IQR 14.5-34) to initiate treatment. Administration ofanti-tuberculosis treatment further delayed referral to specialist centre. Treatment delays were related to performance status, disease stage and treatment type. On multivariate analysis, education and histology affected diagnosis delay and treatment delay. Treatment delay was less in those who received targeted therapy compared to chemotherapy. Various time delays did not affect the overall survival. CONCLUSION: Poor education status and inappropriate anti-tubercular treatment were primary factors associated with longer diagnostic delays. Creating disease awareness and high clinical suspicion are essential to overcome these lacunae in lung cancer care.

Early trends of socio-economic and health indicators influencing case fatality rate of COVID-19 pandemic.

Coronavirus disease 2019, i.e. COVID-19, started as an outbreak in a district of China and has engulfed the world in a matter of 3 months. It is posing a serious health and economic challenge worldwide. However, case fatality rates (CFRs) have varied amongst various countries ranging from 0 to 8.91%. We have evaluated the effect of selected socio-economic and health indicators to explain this variation in CFR. Countries reporting a minimum of 50 cases as on 14th March 2020, were selected for this analysis. Data about the socio-economic indicators of each country was accessed from the World bank database and data about the health indicators were accessed from the World Health Organisation (WHO) database. Various socioeconomic indicators and health indicators were selected for this analysis. After selecting from univariate analysis, the indicators with the maximum correlation were used to build a model using multiple variable linear regression with a forward selection of variables and using adjusted R-squared score as the metric. We found univariate regression results were significant for GDP (Gross Domestic Product) per capita, POD 30/70 (Probability Of Dying Between Age 30 And Exact Age 70 From Any of Cardiovascular Disease, Cancer, Diabetes or Chronic Respiratory Disease), HCI (Human Capital Index), GNI(Gross National Income) per capita, life expectancy, medical doctors per 10000 population, as these parameters negatively corelated with CFR (rho = -0.48 to -0.38 , p<0.05). Case fatality rate was regressed using ordinary least squares (OLS) against the socio-economic and health indicators. The indicators in the final model were GDP per capita, POD 30/70, HCI, life expectancy, medical doctors per 10,000, median age, current health expenditure per capita, number of confirmed cases and population in millions. The adjusted R-squared score was 0.306. Developing countries with a poor economy are especially vulnerable in terms of COVID-19 mortality and underscore the need to have a global policy to deal with this on-going pandemic. These trends largely confirm that the toll from COVID-19 will be worse in countries ill-equipped to deal with it. These analyses of epidemiological data are need of time as apart from increasing situational awareness, it guides us in taking informed interventions and helps policy-making to tackle this pandemic.

Revisiting bronchoscopic intratumoral chemotherapy in malignant central airway obstruction via EUS-B approach and its review of literature.

Critical central airway obstruction has always been a dreaded complication to which interventional pulmonologist commonly encounters. There have been various modalities which are used for the management and palliation, which includes mechanical coring, laser, cryoextraction, electrocautery and airway stenting. Rigid bronchoscopy with or without jet ventilation has been corner stone of therapeutics and palliation of central airway obstruction. There are only a few conditions where it is not possible to use rigid bronchoscopy. Here we report a case of metastatic tracheal tumour which presented with critical airway obstruction in a patient who had atlantoaxial instability (AAI) due to rheumatoid arthritis. Here we used endobronchial ultrasound scope (EBUS) via esophageal route, i.e. EUS-B guided approach for sampling of the tracheal tumour, and intratumoral chemotherapy was instilled in multiple sessions, which resulted in shrinking of tumour, thus relieving the critical airway obstruction. This is the first report of using EUS-B approach for intratumoral chemotherapy for tracheal tumors. Bronchoscopic intratumoral chemotherapy therapy (BITC) in tracheal tumors is also one of the options but has not been explored much and there has been a dearth of literature for it.

Effects of stage-matched repeated individual behavioural counselling session (RIBCS) as an intervention for decreased and stopping smoking.

We aimed to evaluate the effects of stage-matched repeated individual behavioural counselling (RIBCS) on the basis of the transtheoretical model (TTM) as an intervention to reduce and stop smoking. This study was conducted over a period of one year where all smokers presenting to a chest clinic in a tertiary centre were enrolled, each was classified on the basis of stage of readiness to change and underwent repeated counselling for a period of six months and each session was preceded and succeeded with filling of Fagerstorm test for nicotine dependence. Over the period of a year, 207 patients participated in this study, the mean age was 50.74±14.74 years; mean duration of tobacco use was 29.43±14.72 years; 64.3% were illiterate, 11.6% primary education, 14.1% were matric and while 10.1% were graduate. About 73% of smokers reported high level of nicotine dependence (FTND score >5/10). In the present study mean dependence score was 6.0±1.96; 44 (21.3%) were in pre-contemplation stage, 93 (44.9%) were in contemplation, 57 (27.5%) were in preparation and 13 (6.3%) were in action. The point prevalence excellence rate in follow up-I was 15%, follow up-II was 35.3% and follow up-III was 61.9% which was statistically significant. When we took both abstinence and reduction in smoking behaviour as one, p-value was <0.05. The point prevalence of abstinence rate (questionnaire validated) 1 month to 6 months was almost 4 times. Our intervention (RIBCS) succeeded in increasing the abstinence rates during the study period among smokers with a lower motivation to quit (pre-contemplators and contemplators) as well as those ready to quit (preparators). This is significant because of most existing smoking-cessation interventions target only motivated smokers, with few having a positive effect in smokers with a lower motivation to quit.

Personal Protective Equipment: A Pandora's Box.

Countries all over the world writhing under the wrath of coronavirus face not only the challenge of protecting their population but the tougher challenge of protecting their healthcare workers (HCWs) dealing with the patient population. This pandemic has put unprecedented pressure on global healthcare systems, with personal protective equipment (PPE) being the most notable one. Apart from the challenge of procurement of PPE, the major challenge is rationalizing the use of PPE in this war against corona virus disease 19 (COVID19). Using PPE comes with its own set of problems such as extreme exhaustion, rashes, inability to consume food, or use washroom which can result in clouding of judgment and breach of infection barrier. Making PPE user-friendly and limiting the interaction of HCW with COVID19 patients coupled with the use of robotics, telemedicine, and other innovations is the need of the hour.

Obstructive sleep apnoea with co existent Kleine-Levine syndrome in a middle-aged man.

Hypersomnia is a symptom which is pathognomonic of patients with Kleine-Levin syndrome (KLS), but the cause of this finding remains undefined. Given the pervasive association between obstructive sleep apnoea (OSA) and excessive daytime sleepiness, there exists the possibility that OSA might contribute to the sleepiness exhibited by these patients. Here we report a middle age man who had excessive daytime sleepiness and diagnosed as OSA after polysomnography. Prescribing of continuous positive airway pressure (CPAP) lead to unmasking of episodes of increased sleepiness and other behavioural features of KLS.

Pancreatic pleural effusion masquerading as right sided tubercular pleural effusion.

Pleural effusion is easily diagnosed often managed optimally with standard protocols. It at times, is a diagnostic dilemma as it comes with big list of differential diagnosis. Pleural effusion due to pancreaticopleural fistula (PPF) is a rare and on right side is even rarer. Detailed history along with high index of suspicion in required to diagnose PPF, which is confirmed by increased level of pleural fluid amylase and lipase along with magnetic resonance cholangiopancreatography (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP) demonstrating fistula tract. Here we report the case of a young patient who presented with respiratory distress and was wrongly diagnosed as right sided tubercular effusion which later turned out to be pancreatic effusion. Management in our case was multi-disciplinary involving pulmonologist, gastroenterologist, radiologist and thoracic surgeon.

A Rare Case of Neurogenic Pulmonary Edema Following High-voltage Electrical Injury.

Electrical injuries though infrequent, are potentially devastating form of injuries which are associated with high morbidity and mortality. The severity of the injury depends upon intensity of the electrical current which is determined by the voltage and the resistance offered by the victim. These injuries vary from trivial burns to death. There have been few reports about pulmonary injuries due to electrical current but none mentioning neurogenic pulmonary edema (NPE). Here we report a young boy who when exposed to high-voltage current developed neurogenic pulmonary edema and was successfully managed. Though there is no specific protocol for electrical injury but identifying the organs involved along with type of disease facilitates the management.

Noninvasive Ventilation for Acute Respiratory Failure due to Noncystic Fibrosis Bronchiectasis.

PURPOSE OF THE STUDY: Data regarding the use of noninvasive ventilation (NIV) for treatment of acute respiratory failure (ARF) among patients with noncystic fibrosis (CF) bronchiectasis are limited. We intend to describe our experience with NIV use in this setting. METHODOLOGY: This was a retrospective study which included 99 patients with bronchiectasis and ARF who required either NIV or invasive mechanical ventilation (IMV). RESULTS: NIV was started as the primary modality of ventilatory support in 81 (66.3%) patients. Fifty-three (65.4%) patients were managed successfully with NIV. Twenty-eight (34.56%) patients failed NIV and required endotracheal intubation. Reasons for NIV failure were worsening or nonimprovement of ventilatory or oxygenation parameters (n = 15), hypotension (n = 6), worsening of sensorium (n = 3), and intolerance (n = 4). None of the patients failed NIV due to excessive respiratory secretions. The rate of correction of arterial blood gases was comparable between NIV and IMV groups. The total duration of stay (median [interquartile range] days) in hospital was comparable between patients treated with NIV and IMV (8 [7-10] vs. 11 [5-11]; P = 0.99), respectively. The mortality rate between NIV and IMV groups were statistically comparable (8.64% vs. 16.6%; P = 0.08). High APACHE score at admission was associated with NIV failure (odd's ratio [95% confidence interval]: 1.21 (1.07-1.38)]. CONCLUSIONS: NIV is feasible for management of ARF with non-CF bronchiectasis. High APACHE may predict NIV failure among these patients.

Indian tubercular belly: A prospective study of 140 patients of abdominal tuberculosis and their outcomes.

Background: Abdominal tuberculosis is an important yet ignored entity in the spectrum of tuberculosis which has been dominated by pulmonary tuberculosis. Diagnosis and treatment are often delayed due to nonspecific symptoms. In this study, we aimed to highlight the clinical features, diagnostic methods and outcomes of abdominal tuberculosis. Methods: A prospective study was conducted in tertiary referral centre where all patients referred to drug distribution centres (DOTS centre) for abdominal tuberculosis were identified. Their demographic clinical and radiological profile was evaluated. These patients were followed-up for their treatment course for complications and outcomes. Results: A total of 140 patients who were labelled abdominal tuberculosis over a period of 2 years were reviewed at tuberculosis drug distribution centre (DOTS). Mean age of study population was 35.42 ± 12.53 years and majority of the population were males, 58.6% (82). The most common presenting symptom was abdominal pain which was seen in 82.8% (n = 116) of the patients, followed by feverin 65.6% (n = 92); 22.8% (n = 32) were seropositive for HIV and 44.2% (n = 62) had luminal tuberculosis of which ileocecal was the most common site. Peritoneum was second most common site which was involved in 26.4% (n = 37) of the patients followed by mixed tuberculosis involving more than one type. Confirmed diagnosis was achieved in 74 patients (52.8%), while the remaining 66 patients (47.14%) were diagnosed clinically. During follow-up, 12 patients were lost to follow-up; 113 (80.7%) had complete response, while 3 (2.14%) patients died during treatment. Conclusion: Abdominal tuberculosis usually presents with nonspecific complaints which require high index of suspicion. Most patients require only medical therapy which has good results.

Air flow limitation in smokers - A cause of concern.

Introduction: In India smoking is a common habit prevalent in both urban and rural areas irrespective of mode of smoking i.e., cigarettes, bidis, pipes, cigar, hookah etc., Spirometry can be helpful to determine effects of smoking on pulmonary functions. We aimed to study the effect of smoking on the pulmonary function tests. Materials and Methods: This study was conducted on 300 subjects including 150 smokers and 150 non-smokers aged between 25 and 60 years attending a tertiary health care center in northern part of our country. Quantification of tobacco smoking was performed by calculating smoking index. All the study subjects underwent spirometry. Results: All the spirometric variables (FVC, FEV1, PEFR, FEF 25-75%) were lower in smokers as compared to non-smokers and this difference was statistically significant. 76% of the smokers had obstructive, 10.7% had normal, 6.7% had restrictive, and 6.7% had mixed pattern on spirometry. 65.3% of the non-smokers had normal, 28.7% had obstructive and 6% had restrictive pattern on spirometry. Conclusion: Almost all the pulmonary function parameters were significantly reduced in smokers compared to non-smokers and obstructive impairment was common amongst smokers. As early quitting is associated with improved survival, it is important that these asymptomatic smokers are identified early and helped to quit. Primary care physicians being the first point of contact, can play a major role.

Esophageal Cancer, Central Airway Obstruction, and Lots More: A Collaborative Approach to a Challenging Scenario.

Esophageal cancer is the most common cause of extrapulmonary malignant central airway obstruction (MCAO). MCAO is usually managed by a multidisciplinary approach involving tumor debulking, stent placement, and palliative radiotherapy. MCAO is a challenge in itself; here, it becomes even more challenging as it was accompanied by grade 3 oral submucous fibrosis, nasal synechiae, and multiple enlarged cervical nodes causing excessive compression of the trachea along with acute hypercapnic respiratory failure. Herein, a 65-year-old woman with multiple challenges, where death was imminent, managed with a collaborative approach involving awake nasal intubation in the sitting position and placement of a stent via a flexible bronchoscope, as rigid bronchoscopy was not possible in view of limited mouth opening. Overcoming these challenges led to completing the procedure successfully and palliating the symptoms.

New twist to an old problem: COVID-19 and idiopathic pulmonary fibrosis.

Iidiopathic pulmonary fibrosis (IPF) diagnosis and treatment during this COVID-19 pandemic have been affected. COVID-19 has not only impacted the prognosis of these patients but also the approach to these patients. Pulmonary function tests (PFT) and lung biopsies are less encouraged now. Traditional antifibrotics used in IPF should be encouraged irrespective of patient lung function and in those with non-definite usual interstitial pneumonia in high resolution computed tomography.

A review of Ciclesonide in COVID-19. Still a long way to go.

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.

Defying the paradigm - rescue thrombolysis in a postoperative patient with pulmonary embolism.

Parenteral anticoagulation is recommended for patients of intermediate - high early mortality risk pulmonary embolism. Rescue reperfusion is considered if signs of hemodynamic decompensation appear. Recent surgery is a contraindication to thrombolysis. Percutaneous catheter directed thrombolysis and surgical embolectomy can be done in such patients. However, they are not readily available. We hereby report a case of rescue thrombolysis in a post lower segment caesarean section (LSCS) patient with pulmonary thromboembolism. We could successfully achieve thrombolysis in our patient with improvement in clinical and hemodynamic parameters and with no major bleeding from any site.

Mediastinal germ cell tumour masquerading as loculated pleural effusion.

Benign mediastinal teratomas often discovered while patients are still asymptomatic. Almost all arise in the anterosuperior mediastinal compartment. Most symptoms result from compression of adjacent structures. We report a case of a large teratoma arising from the anterior mediastinum that presented a confusing clinical picture of loculated pleural effusion which was successfully diagnosed and treated by surgical excision.

A young non-smoker with high ADA pleural effusion. It's not always tuberculosis.

Lung cancer is posing an ever-increasing medical and social problem due to its increasing morbidity and mortality. Here we report a case of a young male who was being treated as tubercular pleural effusion but was ultimately diagnosed with non-small cell carcinoma. While considering the diagnosis of pleural effusion, in the context of country endemic for tuberculosis like India, it is not surprising that many clinicians rather prefer to consider pulmonary tuberculosis as the first differential, while keeping diagnosis of malignancy as the least likely differential diagnosis in the young patient.
