RESUMO

Lymphangioleiomyomatosis (LAM) is characterised by the proliferation of abnormal smooth muscle cells (LAM cells) in the lungs, lymph nodes and other organs. We report the case of a man in his 50s who had right-sided pleural effusion. On performing a diagnostic tap, the fluid was milky white in colour. An intercostal chest tube was inserted and after complete drainage of fluid, a high-resolution CT (HRCT) was done. HRCT revealed multiple cysts throughout both of the lungs. On subsequent bronchoscopy-guided transbronchial lung biopsy and histochemical staining, diagnosis of LAM was made. We started the patient on oral sirolimus. On subsequent follow-up, subjective and objective improvements were observed.

RESUMO

PURPOSE: Many underserved remote locations without specialists would benefit from the ability to quickly and easily share images of radiographs with trained radiologists using WhatsApp messenger. However, there is limited evidence on the role of WhatsApp messenger for sharing chest x-ray (CXR) images to aid diagnosis and management. The objective of the study was to determine the diagnostic accuracy and inter-observer agreement of WhatsApp messenger images of digital CXR compared to viewing on Picture Archiving and Communication System (PACS) monitor. METHODS: Two pulmonologists reported 400 WhatsApp messenger images of digital CXR each. After a wash period of two weeks, they reviewed the original CXR images on PACS and again reported their findings. Diagnostic agreement was measured using kappa value, diagnostic accuracy was evaluated by sensitivity and specificity. RESULTS: The diagnostic agreement between WhatsApp and PACS images for both the readers was high in case of normal CXR (0.84), Pneumonia (0.85) and Active Koch's (0.79) and Old Koch's (0.71). The inter-observer agreement between two readers on WhatsApp images was good in cases of normal chest x-ray (0.74), Active Koch's (0.61) and Pneumonia (0.74) and low in COPD (0.31) and Pleural Effusion (0.28) and Carcinoma Lung (0.40). In terms of radiological lesion, inter-observer agreement between two readers on WhatsApp images was good in terms of the zonal involvement, moderate in case of infiltrates, consolidation, nodules, and fibrosis, fair in cavity, effusion (0.28) and poor in hilar lymphadenopathy (0.14). The sensitivity in the diagnosis of nodules, effusion and hilar lymphadenopathy was <50% in both the readers. CONCLUSION: CXR transmission via WhatsApp is able to identify clinical findings similar to viewing the same image on a PACS monitor in cases of Pneumonia and normal subjects. Active and old Koch's has good comparability whereas; diagnostic agreement is poor in COPD, cavity, pleural effusion and hilar lymphadenopathy, requiring more caution during interpretation.

RESUMO

BACKGROUND: There is no experience of point-of-care (POC) microbiological confirmation for TB in India in field settings. METHODS: Under the TB-Free Haryana project, a mobile van-mounted digital x-ray and portable GeneXpert system screened all presumptive TB patients with strong clinic-radiological suspicion for TB. RESULTS: Of 1673 x-rays, 215 (13%) had findings suggestive of TB, 109 had strong clinical suspicion and were eligible for POC GeneXpert, in whom a test was performed in 82 (75%) cases; 59 (72%) tested positive and were initiated on treatment within 24 h. CONCLUSIONS: A mobile van equipped with digital x-ray and POC GeneXpert is feasible and has a good success rate with potential for replication.

RESUMO

BACKGROUND: The Tuberculosis (TB) Control Program in India changed the TB diagnostic algorithm and recommended sputum testing and chest x-ray (CXR) for presumptive TB up front. There is no experience of testing this algorithm in routine field settings. METHODS: In a public-private partnership (PPP), a private hospital provided mobile digital CXR services (mounted on a van) to complement the existing diagnostic services of sputum microscopy and GeneXpert testing. All presumptive TB patients (cough >2 weeks) underwent CXR and sputum microscopy, and GeneXpert testing if eligible (smear-negative CXR suggestive of TB). RESULTS: All 2973 presumptive TB patients underwent CXR and sputum microscopy; 471 (15.8%) had abnormal CXR findings suggestive of TB, 129 (4.3%) were smear positive and 17 were extrapulmonary TB. Of the remaining 325 with smear-negative and CXR suggestive of TB, 147 (45.2%) underwent GeneXpert testing, yielding 32 positives (21.8%). Of the remaining 178 with no GeneXpert test done, 106 (60.0%) had CXR definitely suggesting TB (clinically diagnosed TB). Thus a total of 284 cases of TB (161 microbiologically confirmed, 106 clinically diagnosed, 17 extrapulmonary TB) were identified, giving a potential diagnostic yield of 19.6%. CONCLUSIONS: Systematic screening with mobile digital X-ray service via a PPP model integrated into the national program is feasible and scalable with a high yield.

RESUMO

BACKGROUND: There is limited access to radiology facilities in most parts of India leading to significant under diagnosis and underreporting of smear negative clinically diagnosed tuberculosis (CDTB). Public Private Partnership (PPP) has a lot to contribute towards addressing this gap through providing access to chest x-ray (CXR) in far-off locations. METHOD: Mobile vans equipped with digital CXR equipment and support staff were provided by a Corporate Hospital working closely with government, with scheduled visits to government peripheral health institutes. Patients received upfront CXR and sputum microscopy along with GeneXpert in accordance with the revised TB diagnostic algorithm prescribed by the national program, Following a successful pilot in 2014 in district Rewari, "TB free Haryana" was launched in November 2015 with a phased roll out in 16 districts by 2018. RESULTS: The pilot initiative in 2014 confirmed practical and clinical feasibility and revealed a high rate (30% of people screened) of CDTB i.e. symptomatic cases with radiologic abnormalities compatible with Pulmonary TB. In the first year (2016), 5 districts were covered and a total of 3340 CXRs were carried out. There was an increase in the case notification rates of new CDTB (smear negative) in 2016 compared to 2015 (p = 0.036); yielding an additional 180 cases and an 11.67% increase in case detection. Scale up to a total of 13 and 16 districts took place successfully in 2017 and 2018 respectively; with 6268 CXRs and 8021 CXRs done in the respective years. CONCLUSION: PPP can involve Corporate Hospitals to improve the existing diagnostic infrastructure and provides access to CXR in a not-for-profit sustainable collaboration, with scale-up to the state level; and potential to replicate this initiative in other states.

RESUMO

BACKGROUND: Medanta - The Medicity, a multi-super specialty corporate hospital in Gurugram, Haryana launched a "TB-Free Haryana" Campaign; mobile van equipped with a digital CXR machine to screen patients with presumptive Tuberculosis (TB). OBJECTIVES: In this study, we aimed to assess the (1) yield and cost analysis of two strategies using mobile digital x-ray to detect Pulmonary TB in rural Haryana. METHODS: An observational study was conducted on all individuals screened by either of the two case finding strategies using a mobile x-ray unit (MXU) mounted on a mobile van in District Mewat, Haryana during Jan-March 2016. RESULTS: Strategy 1: Out of 121 smear negative cases, x-rays were suggestive of TB in 39(32%), of which 24 were started on TB treatment. Cost of identifying a smear negative TB was US$ 32. Strategy 2: Out of 596 presumptive TB, chest x-rays were suggestive of TB in 108 (18%), of which 67 were started on TB treatment (56 were smear negative TB). Cost of detecting any case of TB was US$ 08 (1 USD = 64 INR). CONCLUSION: The study reports a new initiative within a PPM model to improve the diagnosis of PTB by filling the gap in the current diagnostic infrastructure. We believe there is potential for replication of strategy 2 model in other states, although further evidence is required.

RESUMO

Nearly half of the smear negative pulmonary TB in National TB Programme remain undetected in Haryana (north Indian state), probably due to poor access to chest radiography. A corporate hospital stepped into fill this infrastructure gap in Rewari district of Haryana by sending a mobile van with digital x-ray facilities and paramedic staff. The staff of the public health facility coordinated with the eligible patients and ensured that they visited on the designated day. The District TB Officer interpreted the x-ray and made decisions about diagnosis and treatment. The support was provided between May and Dec 2014 in seven public health centres (primary/secondary level) of the district. A total of 355 patients were examined, of whom 122 (34.4%) were diagnosed as smear negative pulmonary TB and started on treatment according to programme guidelines. This public-private partnership needs to be scaled-up and better designed studies are required to assess community-level impact and cost-effectiveness.
