RESUMO
In view of the high burden of latency of tuberculosis (TB) in India, tackling latent TB in the right way is a menace. All latent TB’s infection (LTBI) are treated in countries having low burden such as the United States. However, this approach cannot be implemented in high burden countries like India until concrete evidence or consensus by experts on this subject is made. There are very specific risk groups where these patients are to be treated as far as current evidence-based medicine is concerned. Hence, the need to develop a document was felt, through which the treatment of LTBI becomes homogeneous by each and every physician who is practicing and treating TB. The last attempt to review the topic was made in 2015, after which there have been many changes and update in this subject.
RESUMO
Purpose: In this study, we intend to analyze ropivacaine and bupivacaine in various parameters during phacoemulsification under deep topical fornix nerve block (DTFNB), a known form of nerve block for phacoemulsification. Methods: This prospective randomized study was conducted on 100 patients undergoing elective cataract surgery by phacoemulsification under DTFNB. Patients were divided into two equal groups of fifty patients each, Groups B (bupivacaine) and Group R (ropivacaine). Two sponges, approximately 2 mm × 3 mm dimensions, saturated with either 0.5% bupivacaine or 0.75% ropivacaine were placed deep in the conjunctival fornices to perform the deep topical block. Both groups were evaluated for magnitude of pain and discomfort at various stages of phacoemulsification using a simple pain scoring system. The level of surgeon satisfaction, requirement for supplementary anesthesia, and surgical complications were also evaluated. Quantitative variables between the two groups were compared using unpaired t-test. Qualitative variables were correlated using Chi-square test. Results: Overall demographic parameters of patients were similar in both groups. Similar mean pain scores were found in the ropivacaine and bupivacaine groups, with no statistical significance. Surgical satisfaction and the need for supplemental anesthesia were also statistically insignificant. Conclusion: Ropivacaine is a good alternative for deep topical anesthesia as it has a better safety margin and lesser toxic effect than other comparable local anesthetic agents.
RESUMO
Pulmonary nocardiosis is an infrequent and severe infection due to Nocardia species, microorganisms that may behave both as opportunists and as primary pathogens. Diagnosis of pulmonary nocardiosis is frequently delayed and a high level of suspicion is required in patients with underlying diseases or chronic corticosteroid therapy. Hereby we are presenting a case of pulmonary nocardiosis mimicking tuberculosis in an immonocompromised patient.
