Background: Excessive daytime sleepiness (EDS), a cardinal symptom of obstructive sleep apnea (OSA) is assessed using Epworth Sleepiness Scale (ESS). Some limitations of ESS include graded responses, inapplicable situations and equal scores for active and passive situations. To overcome these limitations, we developed a novel sleepiness scale and evaluated its performance in patients with OSA. Methods: The study was executed in multiple phases. After determining applicability of items in the ESS, a 6-item questionnaire was developed comprising OSA symptoms and self-reported ‘sleepy’ situations, dichotomized responses and weighted scoring. After content and face validation by experts, the scale was tested for applicability and its performance was compared with ESS in patients with suspected OSA. Results: In phase I, applicability of ESS was tested in 189 participants, of whom 98 (51.8 %) participants found multiple items inapplicable.In phase II, 34 self-reported sleepy situations from 200 participants were narrowed down to a 6-item questionnaire, based on expert validation. This scale was named the Indian Sleepiness Scale (ISS) and was tested for applicability in phase III in 226 participants from diverse literacy backgrounds, who found all situations applicable.In phase IV, ISS and ESS were administered to 335 patients with suspected OSA. OSA was confirmed on polysomnography in 294 (87.7 %) patients. A cut-off score of ≥6 was derived for ISS; at this cut-off score, the ISS which was more sensitive than ESS (71.1 % vs 43.2 %). Conclusions: The Indian Sleepiness Scale was found to be widely applicable and more sensitive than ESS for sleepiness evaluation in patients with OSA.

Abstract Massive pulmonary thromboembolism (PE) is a cardiorespiratory emergency and can be fatal if left untreated. The recommended treatment for PE in the presence of right ventricular dysfunction and hemodynamic instability is thrombolysis. However, the latter is a double‐edged sword as life‐threatening bleeding manifestations can occur post‐thrombolysis. Timely identification and management of these complications can prevent a catastrophic outcome. We report a case of mediastinal hematoma with new onset hemodynamic compromise following thrombolysis for acute massive pulmonary embolism. Clinico‐radiological features and Point of Care Ultrasound (POCUS) findings helped in the identification of the bleeding site in our case. Despite early diagnosis and timely intervention, the patient succumbed to secondary complications.

Mucormycosis is a fatal angio-invasive fungal infection associated with a high mortality. Apart from the traditional risk factors, COVID-19 infection and steroid therapy for the same have been recently identified to predispose to this life-threatening infection. Usual presentations of mucormycosis include rhino-orbito-cerebral, pulmonary, gastrointestinal, renal and cutaneous involvement. We report an unusual case of mediastinal involvement by mucormycosis in a patient recovering from moderate COVID-19 pneumonia. Early diagnosis, prompt initiation of antifungal therapy accompanied by timely surgical debridement were pivotal in averting morbidity and mortality in this patient.

Background: Although muscle dysfunction is a major contributor to morbidity in chronic obstructive pulmonary disease (COPD), assessment of skeletal muscle, and diaphragm function is not routinely performed in COPD patients.Objectives: (1) The aim is to assess muscle dysfunction in COPD by measuring the zone of apposition of diaphragm, diaphragm excursion, thickness of diaphragm, and rectus femoris cross-sectional area (RFCSA) with ultrasonography.(2) To correlate the above assessments with spirometric parameters; notably forced expiratory volume in 1 s (FEV1).Methods: Twenty-four consecutive stable COPD patients and 18 controls were included after obtaining written informed consent. Demographic and clinical data, spirometric values, 6-min walk distance, and sonographic parameters mentioned above were compiled for the analysis. Results: All included participants were male with a mean age of 62.5 ± 8.4 years. The mean FEV1in cases was 1.12 ± 0.4 L versus 2.41 ± 0.5 L in controls. The diaphragm thickness (1.8 ± 0.5 mm vs. 2.2 ± 0.6 mm;P = 0.005) and RFCSA was significantly lower in COPD patients (4.8 ± 1.3 cm[2] vs. 6.12 ± 1.2 cm[2];P = 0.02). However, diaphragm excursion (5.35 ± 2.8 cm vs. 7 ± 2.6 cm) although lower in COPD patients, was not significantly different between the groups. Correlation between FEV1and ultrasound diaphragm measurements and RFCSA by Spearman's Rho correlation was poor (ρ= 0.2). Conclusion: Ultrasonographic assessment of the diaphragm and rectus femoris can be used as markers to assess skeletal muscle dysfunction in COPD as diaphragmatic function and RFCSA were lower in COPD patients.

Background: Administration of local airway anesthesia is the principal determinant of procedural comfort during flexible bronchoscopy. However, the ideal method of administration is still unknown. In this study, we compared lignocaine administration using a spray catheter (SC) with “spray-as-you-go” technique. Methods: Patients undergoing bronchoscopy were randomized to receive airway anesthesia with 2% lignocaine through the SC (SC group) or “spray-as-you-go” technique through the working channel (WC group). The primary outcome parameter was cough count, and the secondary outcome parameters compared were need for sedation, operator-rated procedural satisfaction and cough, and patient-rated comfort on a Visual Analog Scale (VAS). Results: One hundred and thirty patients were randomized with comparable baseline parameters. The median (interquartile range [IQR]) cough count was 28 (19, 37) in the WC group and 15 (9, 23) in the SC group (P < 0.001). Requirement for sedation was lower in the SC group (5 vs. 18; P = 0.003). The mean (standard deviation [SD]) VAS score for operator-rated satisfaction was 66.5 (16.8) in the WC group and 80.6 (14.2) in the SC group; P < 0.001. The median (IQR) VAS score for operator-rated cough was 35 (23, 44) in the WC group and 18 (11, 28) in the SC group; P < 0.001. However, there was no difference in the patient-rated comfort VAS (mean [SD] of 66.4 [14.5] in the WC group and 69.9 [13.0] in the SC group; P = 0.07). Conclusion: Lignocaine instillation using the SC during bronchoscopy reduced cough, need for sedation, and improved operator satisfaction.

Electronic nicotine delivery systems were developed over a decade ago to simulate the experience of smoking, although with a lower exposure to toxins than in conventional smoking. However, they have their own unique profile of side effects, some of which can be life threatening. We report the case of a young male, who in a desperate bid to de-addict himself from smoking developed a serious adverse effect related to the e-cigarettes.

Abstract Background Pneumothorax can present as a respiratory emergency and has varied etiology. However, literature available on assessment and management of primary spontaneous pneumothorax (PSP) based on radiological quantitation is scarce. This study was undertaken to compare two different methods of quantitating pneumothorax size with that recommended in American Thoracic Society (ATS) guideline on chest radiogram with respect to possible change in management practices. Patients and methods A prospective cohort of adults presenting with spontaneous pneumothorax (SP) over 3 years to Emergency and Pulmonology Department, St John’s Medical College Hospital, Bangalore, was included. Demographic characteristics and clinical presentation were compiled. Management of SP was based on ATS guidelines. PSP size on chest radiogram was requantitated in the included patients using Light’s index and Collin’s method and was compared with that proposed by the ATS guideline. Results Seventy-six participants with SP were studied; their mean age was 43.7 years, with a preponderance of male patients (84.2%). Twenty-four (31.6%) patients had PSP and 52 (68.4%) patients had secondary spontaneous pneumothorax. In PSP, there was poor agreement between various methods of estimating size of pneumothorax on chest radiogram (Kappa statistic=0.23; ICC of 0.263). Three (12.5%) of the 24 incidences of PSP, which were treated conservatively as per ATS guidelines, would have required invasive intervention if Light’s index or the Collin’s formula were taken into consideration. Conclusion There was poor agreement of radiological pneumothorax size estimation by Collin’s, Light’s, and that proposed in the ATS guidelines. Thus, a unified, standardized method of radiological assessment of PSP is required.

Aims: The aim of our study was to compare the outcome of Kasai portoenterostomy (KPE) in children with biliary atresia (BA) older than 90 days to children less than 90 days and to study its safety and efficacy in children older than 90 days. Subjects and Methods: Relevant data were collected from our prospectively maintained database of all children with BA who underwent KPE over a 5-year period. Children were divided into two groups: Group 1 ≤90 days and Group 2 >90 days. Data analyzed and compared included total and direct bilirubin, aspartate aminotransferase-to-platelet ratio index (APRI), and the outcome of procedure which was defined as a serum direct bilirubin

Background/Aims: Biliary atresia (BA) is a cholangio-destructive disease of the infant liver presenting with features of obstructive cholangiopathy. The Kasai portoenterostomy (KPE) is the first line of management. The aim of our study was to identify the characteristic features of liver histology in BA that impact the outcome of KPE. Patients and Methods: Data from 30 consecutive children was retrieved from our prospectively maintained database of children undergoing KPE. This included basic demographics, laboratory values and histopathological data from liver biopsy. The stages of fibrosis, presence of ductal plate malformation (DPM), giant cell transformation, extramedullary hematopoiesis and area percentage of α-SMA (α-smooth muscle actin) expression was correlated with jaundice clearance after KPE using standard statistical tests. Native liver survival was computed. Results: Overall, 13 (43%) children cleared jaundice in this series and 10 (33%) are alive with native liver. Lower area percent expression of α-SMA correlated with increased probability of jaundice clearance after KPE (P < 0.001). There was no correlation between stage of fibrosis and jaundice clearance (P = 0.52). DPM, giant cell transformation and extramedullary hematopoiesis did not correlate with outcome. All children who are alive with native liver had lower expression of α-SMA. Conclusion: α-SMA expression may be a potential predictor of jaundice clearance and native liver survival after KPE.

INTRODUCTION: Asthma is a significant public health problem. The severity of asthma varies from patient to patient and the reasons for this are not fully understood. Atopy is known to play an important part in the pathogenesis of asthma. Sensitization to aeroallergens like house dust mite, animal dander from pets and environmental fungi are evaluated in asthmatics. Severe asthma seems to be associated to environmental fungi with sensitization especially to Aspergillus species. AIMS AND OBJECTIVE: The study aimed at determining the prevalence of Cutaneous Sensitization to Aspergillus species by Skin Prick Test (SPT) in moderate- severe asthmatics. MATERIAL AND METHODS: This study was done on 205 clinically diagnosed asthmatic patients, between September 2012 and August 2013. SPT and spirometry was done in all subjects along with a detailed history. RESULTS: The prevalence rate of Aspergillus sensitized patients is 59.5%. Observations of this study also suggest that the severity of asthma is more in Aspergillus sensitized patients when compared to non-sensitized patients and the duration of asthma was more in Non sensitized. There was no significant association between AEC, total IgE levels and Aspergillus species culture positivity in Aspergillus sensitized patients. Aspergillus terreus was the predominant fungal isolate from both SPT positive and negative patient. There was no significant correlation of fungal culture with SPT. CONCLUSIONS: High levels of Aspergillus sensitization is seen in south Indian subjects and is associated with greater severity and shorter duration of asthma.

Aims and Objectives: Biliary atresia (BA) is a cholangiodestructive disease of the biliary tree. The first line of treatment is a Kasai portoenterostomy (PE) following which patients may develop cholangitis. We studied the effect of early cholangitis on the outcome of PE, namely jaundice clearance and early native liver survival (NLS). Methods: We reviewed the data of all children who developed cholangitis after PE from our prospectively maintained database of children with BA. The standardized treatment of all children in the database is described. The frequency and nature of these episodes were characterized, and the outcome of PE and NLS 1 year after PE was calculated. Results: Of 62 children who underwent PE in our institutions, 27 developed cholangitis. All episodes of cholangitis occurred within 14 months of PE. Of 25 children who cleared jaundice in the overall series, 19 had cholangitis. The incidence of cholangitis was significantly higher in children who cleared jaundice. Nine children who had cholangitis are alive with native livers for more than 1 year after PE. Twelve children had intractable cholangitis. Three of these children are alive with native liver 1 year after PE. Conclusion: In our series, cholangitis occurred in most children who cleared jaundice. Furthermore, the 1-year NLS of children who developed cholangitis was 33%.

Opportunistic infections caused by fungi and unusual bacteria are predominantly encountered in the setting of immunosuppressed host. Co-infections with multiple such organisms can pose multiple challenges even to the astute clinician from establishing the diagnosis to drug interactions during treatment of such infections. We hereby present one such case of a triple opportunistic infection in an immunocompetent host and the difficulties faced in the therapeutic decision making.

The diverse clinicopathological spectrum of pulmonary aspergillosis is a consequence of varying levels of invasiveness of this ubiquitous fungus, which largely depends on the host immune response and pre-existing lung disease. The clinical presentation of pulmonary aspergillosis spans a wide spectrum from hypersensitivity to life threatening angio-invasive and disseminated disease. We report the case of a young immunocompetent male with no underlying lung disease, who presented with an incidentally detected ‘infective mass’ lesion in the lung associated with minimal respiratory symptoms. The diagnostic challenges posed by the unusual clinical, radiological and histological picture as well as the therapeutic dilemmas faced are discussed in this report.

BACKGROUND: Scant information is available on the prevalence of restless legs syndrome (RLS) among patients with chronic kidney disease (CKD) on hemodialysis and its correlation with peripheral iron status. This study was carried out to estimate the prevalence of RLS among patients with chronic renal failure on hemodialysis and to correlate the presence of RLS with peripheral iron status. METHODS: Adults diagnosed with CKD were studied. Demographic details, comorbid illness, and the number of years diagnosed with CKD and on dialysis were noted. RLS was diagnosed based on the International RLS Study Group criteria. Severity of RLS was assessed by international restless legs scale (IRLS) severity score. The presence of RLS was correlated with peripheral iron status. RESULTS: The mean age of 116 subjects was 50.7±13.6 years. Of the total subjects, 79 (68.1%) were men. The mean body mass index of the subjects was 22.02±3.5kg/m2. The subjects had CKD for a mean duration of 3.5±3.2 years and were dialyzed for 2.5±2.3 years. The prevalence of RLS was found to be 10.3% (12/116). Five subjects each had mild and moderate RLS by IRLS severity score and two had severe RLS. All 12 patients with RLS were hypertensive. Hemoglobin and serum ferritin levels were higher in patients with RLS as compared to those who were RLS negative with CKD. CONCLUSION: RLS was previously undiagnosed in this population. Considering RLS, peripheral iron measures are of questionable validity in patients on hemodialysis. Measures to early diagnosis and prompt treatment should be taken, as RLS is known to cause impairment of daytime functioning, disturbed sleep, and increased mortality.

Lung ultrasound (LUS) has been proven to yield valuable information for lung and pleural pathology. It is well validated for assessing extravascular lung water. It can also be used to monitor stages of controlled lung de-aeration in whole lung lavage (WLL) which is the treatment for Pulmonary Alveolar Protienosis (PAP),characterized by abnormal surfactant in the alveoli affecting gas exchange .LUS can help decide the point of termination of lung flooding. A 55 year old lady with biopsy proven pulmonary alveolar proteinosis presented with respiratory failure. WLL was planned. LUS was used to study the stages of lung flooding as previously described for ARDS model.6 areas screened based on six areas that are normally examined like upper zone, mid zone and lower zone showed alveolar interstitial pattern. One lung ventilation (OLV) was done and isolation of lavage lung was confirmed which was seen as lung collapse (lung pulse) on LUS. Saline infusion resulted in increase in B lines followed by tissue like pattern with fluid bronchogram on LUS(alveolar flooding) in all the areas. During the lavage of the second lung, appearance of alveolar flooding pattern resulted in termination of saline infusion. The use of LUS in monitoring WLL reduced amount of saline used for lavage, pick up complications like pleural effusion and spillage.

Objectives: To estimate the occurrence of obstructive sleep apnea (OSA) and its risk factors in a rural Indian population using screening questionnaire and Level III sleep study. To determine the feasibility to train community health workers to administer Level III sleep study in the high-risk population. Materials and Methods: The study was conducted from seven villages with adult population of 2247, in Mugalur, near Bengaluru, from January to April 2014. Berlin questionnaire was used to screen 321 participants chosen by stratified random sampling. A total of 26 out of 321 patients underwent Level III sleep study at home, administered by the health workers, who were trained in three sessions to hook up the machine. Data were verified by a certified sleep physician. Results: The mean age was 39.43 ± 15.6 years with the M:F ratio of 0.98:1. Prevalence of risk of OSA by Berlin questionnaire was 8.72% (95% confidence interval [CI] 5.63, 11.81) in the total population, 7.4% in males and 11.7% in females. Older age (odds ratio [OR] 3.97; CI 1.63, 9.6), hypertension (OR 11; CI 4.3, 28.2), obesity (OR 2.35; CI 1, 5.5), and higher Mallampati score (OR 3.78; CI 1.7, 8.4) were significantly associated with high risk of OSA (P = 0.0001–0.04). Twenty-six patients underwent Level III sleep study and OSA was diagnosed in 12 patients. The mean apnea–hypopnea index (AHI) of this group was 9.7/h. The prevalence of OSA by AHI criteria was 3.74%. Conclusions: OSA is underdiagnosed in rural populations, although risk factors are present. Training community health workers to administer Level III sleep study is a feasible and cost-effective strategy.

Actinomyces naeslundii is a commensal flora of the oral cavity and is generally considered as an avirulent saprophytic bacterium in immunocompetent patients. It can become an opportunistic anaerobic pathogen in oral cavity in patients with poor oral hygiene or tooth extraction and can cause periodontal disease. Pulmonary Actinomycosis is a rare manifestation and may be suspected in middle-aged male patients with cough and hemoptysis showing radiological findings of a peripheral mass or chronic consolidation in whom repeated aerobic cultures have yielded negative results. Here, we report isolation of A. naeslundii from the bronchoalveolar lavage sample from an immunocompetent patient who presented with chronic nonresolving pneumonia of 6 months duration.

Aims: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing "extended" Kasai portoenterostomy (KPE), a modification of the original procedure. Materials and Methods: Since 2013, we have used the technique of "extended KPE" and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). Results: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ΁ 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. Conclusion: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA.

Background: Chylothorax is a rare complication of gastric adenocarcinoma and data on its identification, prevalence and outcomes are scant. Objectives: To enable identification of gastric carcinoma as a cause of chylothorax. Methods: A case report and a systematic review were conducted of all reported cases of gastric adenocarcinoma with chylothorax as the presenting complaint in the English literature. Results: Chylothorax is a rare presenting complaint of gastric adenocarcinoma. There are only 18 case reports in the world literature, of which six are in English. Chylothorax occurred variably in gastric adenocarcinoma, either as a presenting feature or as a complication of therapy. Here, we analyze the index case and six patients in whom gastric carcinoma presented with chylothorax as the initial symptom. Respiratory features of cough and dyspnea preempted any abdominal complaint. Bilateral chylothorax (66%) with associated chylous ascites (50%) was common. Four of the six patients had skin lymphedema also as a prominent feature. The chylothoraces have been treated by therapeutic pleurocentesis, intercoastal tube drainage and restriction of oral intake. Gastric adenocarcinoma was associated with high mortality (50%) and morbidity. Conclusions: Chylothorax can be the presenting feature of gastric adenocarcinoma. A thorough search for this life-threatening disease should be done before labeling the chylothorax as idiopathic.

Aims and Objective: The aim of this study was to describe the occurrence of sleep disordered breathing/obstructive sleep apnea (OSA) in patients admitted with acute myocardial infarction (MI) in a tertiary care hospital. Materials and Methods: All consecutive patients with a recent MI, presenting to the hospital for a period of over 1 year, were administered with a well-designed questionnaire and subjected to polysomnography (PSG) after obtaining a written informed consent. Results: A total of 55 patients were screened with the questionnaire and 44 patients were subjected to PSG. Of the 55 patients 42 (76.4%) were snorers and 14 (25.5%) were insomniacs. OSA was diagnosed in 12 (28.6%) of the 44 patients. There was no significant difference in the presence of hypertension, diabetes mellitus or hypercholesterolemia among the patients diagnosed with OSA and those without OSA. Conclusions: There is a high prevalence of previously undiagnosed OSA in patients admitted to the hospital with acute MI as compared to the general population. OSA is under-recognized in India. Early recognition of undiagnosed OSA in this population of patients with coronary artery disease (CAD), and treatment of the same would help in reducing cardiovascular morbidity and mortality. This study reinforces the need for the routine screening of MI/CAD patients for the presence of OSA.

Biliary diversion offers a potential option for intractable pruritus in children with chronic cholestatic disorders. Progressive familial intrahepatic cholestasis (PFIC) is an inherited disorder of impaired bile acid transport and excretion, which presents with jaundice and pruritus in the first few months of life and progresses to cirrhosis by infancy or adolescence. We report a child with PFIC type 1 who underwent internal biliary diversion for intractable pruritus and was relieved of his symptoms.

We describe anaesthesia in a child suffering from Treacher Collins Syndrome (TCS) posted for craniofacial reconstruction by mandibular distraction with external fixator
