RESUMEN
BACKGROUND: During recent outbreak of dengue fever in Delhi, there has been a significant increase in dengue-associated admission in hospitals. To better understand the pathology of dengue haemorrhagic fever, we conducted autopsies of dengue infections deaths within our hospital. METHOD: This was an autopsy study of dengue-associated deaths at a large tertiary care hospital. RESULTS: From Sep 2009 to Dec 2010, a total of 1032 patients with serological evidence of dengue infection were admitted to our hospital. There were twelve deaths and autopsies were conducted in six. Adult respiratory distress syndrome, bleeding diathesis, hypotension, hepatic failure and acute renal failure were the common causes of death despite early hospitalization, intravenous fluid, and blood-product support. CONCLUSION: Dengue is associated with severe disease, and deaths do occur despite current supportive management. Early predictors of disease severity and better clinical interventions are needed.
RESUMEN
BACKGROUND: Axshya SAMVAD is an active tuberculosis (TB) case finding (ACF) strategy under project Axshya (Axshya meaning 'free of TB' and SAMVAD meaning 'conversation') among marginalized and vulnerable populations in 285 districts of India. OBJECTIVES: To compare patient characteristics, health seeking, delays in diagnosis and treatment initiation among new sputum smear positive TB patients detected through ACF and passive case finding (PCF) under the national TB programme in marginalized and vulnerable populations between March 2016 and February 2017. METHODS: This observational analytic study was conducted in 18 randomly sampled Axshya districts. We enrolled all TB patients detected through ACF and an equal number of randomly selected patients detected through PCF in the same settings. Data on patient characteristics, health seeking and delays were collected through record review and patient interviews (at their residence). Delays included patient level delay (from eligibility for sputum examination to first contact with any health care provider (HCP)), health system level diagnosis delay (from contact with first HCP to TB diagnosis) and treatment initiation delays (from diagnosis to treatment initiation). Total delay was the sum of patient level, health system level diagnosis delay and treatment initiation delays. RESULTS: We included 234 ACF-diagnosed and 231 PCF-diagnosed patients. When compared to PCF, ACF patients were relatively older (≥65 years, 14% versus 8%, p = 0.041), had no formal education (57% versus 36%, p<0.001), had lower monthly income per capita (median 13.1 versus 15.7 USD, p = 0.014), were more likely from rural areas (92% versus 81%, p<0.002) and residing far away from the sputum microscopy centres (more than 15 km, 24% versus 18%, p = 0.126). Fewer patients had history of significant loss of weight (68% versus 78%, p = 0.011) and sputum grade of 3+ (15% versus 21%, p = 0.060). Compared to PCF, HCP visits among ACF patients was significantly lower (median one versus two HCPs, p<0.001). ACF patients had significantly lower health system level diagnosis delay (median five versus 19 days, p = 0.008) and the association remained significant after adjusting for potential confounders. Patient level and total delays were not significantly different. CONCLUSION: Axshya SAMVAD linked the most impoverished communities to TB care and resulted in reduction of health system level diagnosis delay.

BACKGROUND: There is a great deal of disparity in the incidence of breast cancer in rural and urban India on one hand and between India and Western population on the other. METHODS: We analysed steroid receptor status in cases of breast cancer in a small sample of patients in armed forces. Infiltrating duct carcinomas of breast recorded histologically in mastectomy specimens in last two years were accessioned in the present study with reference to patient and tumour characteristics. RESULT: In contrast to the higher rates reported in western literature, only 33 % of the tumours expressed estrogen receptors (ER) and progesterone receptors (PR), of which 24% were ER positive and 30% PR positive. Negative steroid receptor status did not correlate with presence or absence of metastatic nodes, however it was predominant amongst the high grade infiltrating duct carcinomas in this study. Necrosis and lymphovascular invasion demonstrated an inverse relationship with the ER/ PR reactivity. 70% of the node positive cases expressed Her -2/ Neu, reflecting a higher immunoreactivity in this subset of patients. Aneusomy for chromosomes 1, 11 and 17 was common in node positive cases. CONCLUSION: Evaluation of chromosomal aberrations by Fluorescent In Situ Hybridization (FISH) technique correlates well with traditional histological parameters.
RESUMEN
BACKGROUND: There is limited evidence on whether active case finding (ACF) among marginalised and vulnerable populations mitigates the financial burden during tuberculosis (TB) diagnosis. OBJECTIVES: To determine the effect of ACF among marginalised and vulnerable populations on prevalence and inequity of catastrophic costs due to TB diagnosis among TB-affected households when compared with passive case finding (PCF). METHODS: In 18 randomly sampled ACF districts in India, during March 2016 to February 2017, we enrolled all new sputum-smear-positive TB patients detected through ACF and an equal number of randomly selected patients detected through PCF. Direct (medical and non-medical) and indirect costs due to TB diagnosis were collected through patient interviews at their residence. We defined costs due to TB diagnosis as 'catastrophic' if the total costs (direct and indirect) due to TB diagnosis exceeded 20% of annual pre-TB household income. We used concentration curves and indices to assess the extent of inequity. RESULTS: When compared with patients detected through PCF (n = 231), ACF patients (n = 234) incurred lower median total costs (US$ 4.6 and 20.4, p < 0.001). The prevalence of catastrophic costs in ACF and PCF was 10.3 and 11.5% respectively. Adjusted analysis showed that patients detected through ACF had a 32% lower prevalence of catastrophic costs relative to PCF [adjusted prevalence ratio (95% CI): 0.68 (0.69, 0.97)]. The concentration indices (95% CI) for total costs in both ACF [-0.15 (-0.32, 0.11)] and PCF [-0.06 (-0.20, 0.08)] were not significantly different from the line of equality and each other. The concentration indices (95% CI) for catastrophic costs in both ACF [-0.60 (-0.81, -0.39)] and PCF [-0.58 (-0.78, -0.38)] were not significantly different from each other: however, both the curves had a significant distribution among the poorest quintiles. CONCLUSION: ACF among marginalised and vulnerable populations reduced total costs and prevalence of catastrophic costs due to TB diagnosis, but could not address inequity.

Metastatic tumor deposits in the umbilicus are not uncommon. Fine-needle aspiration cytology is an important, simple, cost-effective diagnostic tool for delineating the value of umbilical nodules. However, only a few reviews and case reports of diagnosis of umbilical metastases by fine-needle aspiration cytology are available. A review of 52 cases of umbilical nodule aspirates over a 16-yr period forms the basis of this brief report.

Fine needle aspiration cytology (FNA) has a well-documented role in the diagnosis of cysticercosis. However, little is discussed about the associated inflammatory response in the host tissues. Aspirates from 182 cases of subcutaneous cysticercosis were semiquantitated for the type and degree of inflammatory response, and the amount and preservation of the parasite. Tissue sections were reviewed where available. In the FNA where no parasite was observed but a confirmatory tissue diagnosis was available, it was found that eosinophils (52%), epithelioid cell granulomas (30%), palisading histiocytes (33%) and giant cells (28%) were seen less frequently than in those where larval fragments were identified in the aspirated material in varying quantities, the response being 88-92% eosinophils, 50-70% palisading histiocytes, 68-80% epithelioid cell granulomas and 46-74% giant cells. Repair cells were maximally seen when readily identifiable larval fragments were seen in the aspirate. Bizarre cells were equally distributed in these aspirates. The tissue response in FNA from subcutaneous cysticercosis can be varied and eosinophils are found to increase with the presence of the degenerating parasite. In soft-tissue aspirates, palisading histiocytes with epithelioid cell granulomas with or without giant cells and an inflammatory exudate with predominantly eosinophils alerts one to search diligently for a parasite.

Parasites in the human breast are uncommon but not rare. Cysticercus and filariasis in fine needle breast aspirates have been documented and their cytomorphology is well characterised. However, the host tissue response to these parasites and the factors responsible for their initiation are not clear. Over a 21 year period, 28 cases of breast parasites (16 cases of cysticercus and 12 of filariasis), diagnosed by fine needle aspiration cytology, were reviewed to assess the host tissue response.
