Granulomatous Hepatitis with Miliary Mottling: A Rare Cause.

Miliary mottling is most commonly seen in tuberculosis. Clinical features of tuberculosis mimic many other lung diseases. Here we report a 40 yr old male with clinical features suggestive of tuberculosis, miliary mottling on skiagram chest and granulomatous hepatitis on histopathology. Case was finally diagnosed as sarcoidosis on liver biopsy and improved on oral corticosteroid.

An Unusual Presentation in Urinothorax.

Urinothorax is defined as the presence of urine in the pleural cavity. Leakage from the urinary tract can cause urinoma with retroperitoneal urine collection, and secondarily, urinothorax. We report the case of a 35-year-old female who presented with dyspnoea and right-sided chest pain. Chest radiograph revealed a right-sided pleural effusion. The patient had undergone left-sided ovarian cystectomy three months ago, had sustained a left-sided ureteric injury that required ureteric stent placement. Urinothorax was suspected as a consequence of ureteric injury; pleural fluid to serum creatinine ratio was found to be greater than one, confirming the diagnosis.

Tracheal diverticulum: an unusual cause of chronic cough and recurrent respiratory infections.

Tracheal diverticulum (TD) defined as a typical benign out-pouching of the tracheal wall due to structural weakness, congenital or acquired in origin, resulting in paratracheal air cysts. It is rarely diagnosed in clinical practice with only limited reports in the literature. Most cases found incidentally in the postmortem examination and located on the right side. Uncomplicated TDs are usually asymptomatic and when symptoms have occurred, they usually present with non-specific symptoms like pharyngeal discomfort, cough, dyspnea, and recurrent respiratory infection due to either the compression of adjacent organs or secondary bacterial infection. Imaging techniques like thoraco-cervical multi-slice spiral computed tomography (CT) and fiber-optic bronchoscopy are important diagnostic tools for this entity. Asymptomatic TDs usually require no treatment and managed conservatively while surgical excision is indicated in cases of compression of adjacent organs and recurrent infections. Here we report a case of tracheal diverticulum on the left side, which was diagnosed as part of a work-up for chronic cough and recurrent chest infection in a 40 year old female who was already on bronchodilator without any relief. Diagnosis of TD was based on findings of computed tomography, revealing small bud like projection on left para tracheal region and further confirmed by fiber-optic bronchoscopy while the barium contrast study showed no esophageal communication. She was managed conservatively and referred for surgical excision.

Stepping down in asthma.

Beta-2-agonists continue to find a dominant role in all the current guidelines on the management of chronic persistent bronchial asthma. However, the safety of the drugs remains doubtful. Thus, there is a case for review of the "Step up-Step down" approach in the management of chronic persistent bronchial asthma. Based on the currently available experimental and clinical data on bronchial asthma, the authors are of the opinion that chronic persistent bronchial asthma is best managed by a modified "Step I-Step II" approach.

Perspective on the Role of Antibodies and Potential Therapeutic Drugs to Combat COVID-19.

The sudden emergence of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the coronavirus disease of 2019 (COVID-19) has brought the world to a standstill. Thousands of people across the globe are biting the dust with every passing day and yet more are being tested positive for the SARS-CoV-2 infection. In order to dispense this current crisis, numerous treatment options have been tried and tested and many more are still under scrutiny. The development of vaccines may help in the prevention of the global pandemic, however, there is still a need for the development of alternate approaches to combat the disease. In this review we highlight the new discoveries and furtherance in the antibody based therapeutic options and the potent drugs, with special emphasis on the development of the monoclonal and polyclonal antibodies and the repurposed drugs, which may prove to be of significant importance for the treatment of COVID-19, in the days to come. It is an attempt to evaluate the currently presented challenges so as to provide a scope for the ongoing research and assistance in the development of the effective therapeutic options against SARS-CoV-2.

Erasmus Syndrome: Silicosis and Systemic Sclerosis.

Several occupational hazards, especially exposure to silica, have been implicated as causal factors for the development of scleroderma-like disorders. Compared to other connective tissue disorders, silica-associated systemic sclerosis (SA-SS) is relatively rare. Silica-induced scleroderma is indistinguishable from idiopathic systemic sclerosis. However, the former expresses a high predisposition of pulmonary involvement and anti-Scl-70 antibody. We report the case of a 42-year-old male, stone cutter by occupation, who was diagnosed as simple chronic silicosis and developed systemic sclerosis.

Consensus Statement : The Need for Tobacco Harm Reduction in India

Cigarette smoking is a major public health issue in India and leads to significant morbidity and mortality. Addressing the issue of smoking is a major challenge to public health, as the addiction is hard to break. Counseling smokers regarding smoking cessation is the first step to achieving cessation, but the quit rates remain low. Several pharmacological interventions have been developed over the years. Nicotine replacement therapy is available in a variety of formulations, each with different advantages, drawbacks, acceptability among smokers and quit rates. In addition, a range of novel nicotine and tobacco products, including Heated Tobacco Products (HTPs), have been developed which leverage nicotine to aid in smoking cessation. A group of medical experts convened to review the evidence on the burden of smoking, the concept of Tobacco Harm Reduction (THR), novel nicotine and tobacco products for THR, and the potential of HTPs to aid in smoking cessation. This paper outlines the findings and recommendations regarding THR in the Indian context. The panel opined that tobacco cessation centers and counseling remain the foundation of tobacco cessation in India. At the same time, there appears to be potential for the application of THR products in India. The relevant authorities must review the potential of THR products, and make these available, to provide the best possible cessation strategy for the Indian population that is currently at risk of mortality and severe morbidity.

A comparative study of itraconazole in various dose schedules in the treatment of pulmonary aspergilloma in treated patients of pulmonary tuberculosis.

INTRODUCTION: The optimal dose, duration, and efficacy of itraconazole in Indian patients of pulmonary aspergilloma (PA) are not clearly defined. Therefore, a study was carried out, to resolve these issues in diagnosed cases of PA complicating old treated patients of pulmonary tuberculosis. MATERIALS AND METHODS: The study patients randomly received itraconazole either in a fixed dose schedule of 200 mg (group I), 200 mg twice daily (group II) or a variable dose schedule (group III), for 12 months. All the patients were followed up for the entire duration of the study for clinical, radiological, and immunological response. The side effects were recorded as and when reported by the patients and managed symptomatically. RESULTS: A total of 60 patients were enrolled, 20, in each group. There were no intergroup differences with regard to age, sex, body weight, smoking status, alcohol intake, symptoms, Potassium hydroxide (KOH) mount, fungal culture, pattern of radiological lesions or anti-aspergillus antibodies (anti-Asp-Ab) titers. The radiological response was poor in group I patients, as compared to the other groups, at two months (P < 0.05). The dose of itraconazole was increased in five of the patients in group I due to poor response. A higher number of group II patients suffered side effects and the dose of itraconazole had to be decreased in three of these patients, but none of the patients on a variable dose schedule required a change in dose schedule. CONCLUSION: Thus, a weight-based variable dose schedule of itraconazole was found to be a more effective and safer modality in the management of PA than a fixed dose schedule.

Pattern of Drug of Resistance in Previously Treated Pulmonary Tuberculosis with Line Probe Assay

Background: Tuberculosis is global health problem known since ancient times. Drug-resistant TB has been known from the time of anti-TB drugs were first introduced for the treatment of TB. The emergence of drug resistant tuberculosis particularly MDR TB has become significant health problem worldwide and an obstacle to effective tuberculosis control. Line Probe Assay (LPA) is a Nucleic Acid Amplification Test (NAAT) which provides rapid diagnosis of R and H resistance and yield results in 72 hours.Literature on drug resistant pattern in patients who are previously treated for tuberculosis and/or suspected MDR cases with Line Probe Assay method are not studied hence this study was carried out. Aims and objectives: To know the drug resistance pattern of Rifampicin and Isoniazid in previously treated pulmonary tuberculosis cases and correlating with the demographic characteristics of patients. Methods: This study was carried out in department of Respiratory Medicine, Mahatma Gandhi Medical College and Hospital, Jaipur in AFB smear positive patients of pulmonary tuberculosis who have previously taken treatment, before reporting at OPD/IPD. The exclusion criterion was new cases of pulmonary tuberculosis. Detailed history, examination and investigations were carried out. The diagnosis of active pulmonary TB was based sputum smear examination by Ziehl - Nelson staining method. Sputum smear positive cases were subjected to line probe assay to detect resistant pattern at RNTCP accredited laboratory (SMS Medical College and Hospital, Jaipur). Results: A total of 175 previously treated sputum smear AFB positive patients of pulmonary tuberculosis were taken in this study. Out of which 141(80%) were males and 34(20%) cases were females with male : female ratio 4:1 and maximum cases (43.4%) belonged to 31-45 age group with mean age 38 years. Majority of cases belonged to rural area and lower middle class group. More than 2/3rd cases were smokers (72%) among male. Out of 175 cases, 100(57.1%) cases were drug resistant, 75(42.8%) cases were drug sensitive. Line probe assay with regard to resistant pattern was highest in grade +3 sputum (100%) followed by grade +2(98%) and grade +1(96%), while least in scanty sputum positive cases (3%). Resistance to Isoniazid (H), Rifampicin(R) and Both (H+R) were seen in 27%, 14% and 59% respectively. Half of patients (56%) out of total resistance belonged to default category of previously treated pulmonary tuberculosis cases. Resistance to H (27 cases) were 62.5% in relapse, 33.3% in default and 11% in failure cases. Out of R resistance (14 cases), 63% and 37% were in relapse and default cases. Out of 59 cases of H+R resistance 65% belonged to failure category and 20% default and 15% relapse category. Conclusion: Line Probe Assay (LPA) provides accurate and rapid diagnosis of R and H resistance and is recommended for diagnosis of DR-TB in previously treated pulmonary tuberculosis patients.
