Ocular manifestations of common pulmonary diseases: a narrative review.

Several pulmonary disorders can cause ocular involvement. Understanding these manifestations is critical for early diagnosis and treatment. Hence, we set out to examine the most common ocular manifestations of asthma, chronic obstructive pulmonary disease (COPD), sarcoidosis, obstructive sleep apnea (OSA), and lung cancer. Allergic keratoconjunctivitis and dry eye are two ocular manifestations of bronchial asthma. The inhaled corticosteroids used to treat asthma can cause cataract formation. COPD is associated with ocular microvascular changes as a result of chronic hypoxia and systemic inflammation spillover into the eyes. Its clinical significance, however, is unknown. Ocular involvement is common in sarcoidosis, occurring in 20% of cases of pulmonary sarcoidosis. It can affect nearly any anatomical structure of the eye. Obstructive sleep apnea has been linked to floppy eye syndrome, glaucoma, non-arteritic anterior ischemic optic neuropathy, keratoconus, retinal vein occlusion, and central serous retinopathy, according to research. However, while an association has been established, causality has yet to be established. The effect of positive airway pressure (PAP) therapy used to treat OSA on the aforementioned ocular conditions is unknown. PAP therapy can cause eye irritation and dryness. Lung cancer can affect the eyes through direct nerve invasion, ocular metastasis, or as part of a paraneoplastic syndrome. The goal of this narrative review is to raise awareness about the link between ocular and pulmonary disorders in order to aid in the early detection and treatment of these conditions.

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.
