PublicationArticle Analysis of status of surgery in thoracic tuberculosis.(1998) T.K. Lahiri; D. Agrawal; R. Gupta; S. KumarA retrospective analysis of the surgical procedure in 1655 patients in twenty years in a university hospital for thoracic tuberculosis revealed that the varieties of procedures were necessary in 2.2% cases only. They can be grouped as tubercular empyema with or without bronchopleural fistula in 1507 (91%), complicated pulmonary tuberculosis in 78 (4.7%), cold abscess in the chest wall with or without lymphadenitis in 54 (3.2%) and osteomyelitis of the ribs and sternum in 16 cases (0.9%). This is statistically significant with a confidence interval of 0.1248 to 0.2348. In tubercular empyema 222 procedures were performed of which 162 were minor procedures, intercostal drainage with irrigation: 89 cases, thoracostoma: 56 cases and continuous chest wall tube 17 cases and 60 were major procedures (decortication in 45 cases, thoracoplasty [modified] in 14 cases and muscle transfer in one case). All the above procedures were preceded by an intercostal drainage. In complicated pulmonary tuberculosis the operative procedures were as follows: lobectomy in 33 cases, pneumonectomy in 35 cases and thoracoplasty in 10 cases. Drainage of cold abscess with or without lymphnode resection was performed in 54 cases and in 16 cases of osteomyelitis of the ribs and sternum resection were necessary. All procedures were performed under the cover of antitubercular therapy and supportive treatment with the aim of resolution of process, obliteration of the empyema space, control of sepsis and improvement of activity performance. The morbidity was extensive and mortality was high in major procedures. Good results could be obtained in over 92% cases, and only 66.2% on major surgery cases.PublicationArticle Carcinoma of the esophagus in childhood(Springer-Verlag, 1993) N.C. Aryya; T.K. Lahiri; A.N. Gangopadhyay; A.K. AsthanaCarcinoma of the esophagus in children is a rare occurrence. This report describes a case of squamous cell carcinoma of the esophagus in a 10-year-old boy with a brief review of the literature. © 1993 Springer-Verlag.PublicationArticle Cardiovascular patients in pregnancy(1980) T.K.

Lahiri; Anand Kumar[No abstract available]PublicationArticle Discotic nematic-isotropic phase transition properties for a disc-like mesogen(2011) T.K. Lahiri; Shri SinghA statistical mechanical perturbation theory has been used to describe discotic nematic-isotropic phase transition for a discotic liquid crystal, hexa(p-octyl phenyl ethynyl)benzene. We have employed the decoupling approximation, which introduces anisotropy in the pair correlation function, to investigate the discotic nematic-isotropic transition properties. The variation of second rank orientational order parameter with temperature has been computed and it shows qualitatively similar behavior to that of experimental studies of Aver'yanov [1]. However, the numerical value of order parameter at the transition found in the present work is larger than that of Aver'yanov's. The various thermodynamic properties have also been calculated at the transition.

Rajesh; S. SinghWe study in detail the influence of deviations from the molecular cylindrical symmetry on the fundamental elastic properties of uniaxial nematic liquid crystals. Results for the elastic constants are obtained for a range of molecular length-width ratio, temperature, density and molecular parameters. We compare calculated values with the experimental data of 8 OCB. It is observed that the effect of non-cylindrical molecular symmetry on the values of elastic constants of uniaxial of a nematic phase is small. © 1997 Taylor & Francis Ltd.PublicationArticle Hemangioendothelioma of the lung with metastasis.(1993) T.K.

Lahiri; Siddharth Lakhotia; Gopalji GuptaPulmonary blastoma is a rare but aggressive malignancy of the lung comprising epithelial and mesenchymal elements that resemble fetal lung tissue. This report described a case of an 18-year-old male who presented with cough and weight loss for a month. Computed tomography (CT) of the thorax revealed a large mass with mixed solid and cystic lesions on the right side of chest along with pleural effusion and mediastinal lymphadenopathy. Massive debulking was performed followed by chemotherapy. A biphasic pulmonary blastoma was diagnosed on histopathology.PublicationArticle Pulmonary fungal ball in non-immunocompromised patient: A case report(2007) Ragini Jain; D. Agarwal; T.K. Lahiri; Vijai Tilak; A.K. GulatiFungal ball caused by Aspergillus species is an opportunistic infection. We describe a case report of a patient with culture positive Aspergillus fumigatus who presented with complaints of cough and expectoration with recurrent episodes of haemoptysis. Tuberculosis is the commonest cause of haemoptysis in India. However fungal ball is also one of the leading cause of haemoptysis. Hence laboratory evaluation of haemoptysis should not only include work up for tuberculosis but sample should also be submitted for mycological evaluation.PublicationArticle Pulmonary mucoraceous fungal ball.(2001) T.K. Lahiri; D. Agarwal; G.E. Reddy; A. BajoriaA case of opportunistic pulmonary infection in the form of fungal ball produced by the family of mucoraceae in the class of phycomycetes having nonseptate hyphae (cellophane tubules) with haphazard branching in a post-tubercular immunocompetent patient is described. Clinical course was chronic with right upper lobe cavity invaded by fungi of mucor species, pathology was granuloma with blood vessel thrombosis, and a fungus ball. The host had no associated predisposing diseases. Segmental resectional surgery of the right upper lobe along with removal of fungus ball under the coverage of modified dose of amphotericin B was performed. Literature scanning revealed rarity of mucormycosis in immunocompetent host.PublicationArticle Pulmonary nocardiosis presenting as fungal ball--a rare entity.(2008) Ragini Tilak; D. Agarwal; T.K. Lahiri; Vijai TilakPulmonary intracavitary infection caused by Nocardia is an opportunistic infection and is believed to be a rare entity. We describe a case report of a patient with culture positive Nocardia asteroides who presented with complaints of cough and expectoration with episodes of haemoptysis and dyspnoea. The diagnosis of nocardiosis was made by microscopic examination of the surgically resected portion of the lung and confirmed on culture.
