We report here the first case of disseminated Emmonsia pasteuriana infection in a patient with AIDS in India. The patient presented with weight loss, dyspnoea, left-sided chest pain and multiple non-tender skin lesions over face and body for 3 months. Disseminated emmonsiosis was diagnosed on microscopic examination and fungal culture of skin biopsy and needle aspirate of lung consolidation. It was confirmed by sequencing internal transcribed spacer region of rDNA, beta tubulin, actin, and intein PRP8. The patient responded to amphotericin B and itraconazole therapy.

Primary yolk sac tumor of the liver is extremely rare in adults. We report a case of a young man with an unresectable primary yolk sac tumor of the liver, who had a platinum-refractory disease that progressed despite 2 lines of chemotherapy. We review the literature pertaining to primary yolk sac tumor of the liver and its management.

Background While several parameters have emerged as predictors of prognosis of COVID-19, a simple clinical score at baseline might help early risk stratification. We determined the ability of National Early Warning Score 2 (NEWS2) to predict poor outcomes among adults with COVID-19. Methods A prospective study was conducted on 399 hospitalised adults with confirmed SARS-CoV-2 infection between August and December 2020. Baseline NEWS2 score was determined. Primary outcome was poor outcomes defined as need for mechanical ventilation or death within 28 days. The sensitivity, specificity and Area under the curve were determined for NEWS2 scores of 5 and 6. Results Mean age of patients was 55.5 ± 14.8 years and 275 of 399 (68.9%) were male. Overall mortality was 3.8% and 7.5% had poor outcomes. Median (interquartile range) NEWS2 score at admission was 2 (0–6). Sensitivity and specificity of NEWS 2 of 5 or more in predicting poor outcomes was 93.3% (95% CI: 76.5–98.8) and 70.7% (95% CI: 65.7–75.3) respectively [area under curve 0.88 (95% CI: 0.847–0.927)]. Age, baseline pulse rate, baseline oxygen saturation, need for supplemental oxygen and ARDS on chest X ray were independently associated with poor outcomes. Conclusions NEWS2 score of 5 or more at admission predicts poor outcomes in patients with COVID-19 with good sensitivity and can easily be applied for risk stratification at baseline. Further studies are needed in the Indian setting to validate this simple score and recommend widespread use.

11064 Background: Reaching to the correct histo-pathological diagnosis of soft tissue sarcomas (STS) is a great challenge and is cornerstone for treatment planning. Need of expertise for diagnosis is limited by lack of expert pathologists and dedicated sarcoma oncologists in India. Through this study we highlight the pattern of pathological diagnosis and accuracy outside specialist centre. Methods: We did retrospective analysis of all patients referred to us with diagnosis of STS in the last 12 months (January 2016 to 2017). According to protocol, all patients had pathology review from our institute. If blocks were available then they were reviewed and if necessary, fresh biopsy was performed. Besides, pathological diagnosis was reviewed in joint clinic, giving clinico-radiological inputs to sarcoma pathologists. For patients diagnosed outside and had discordant report, we divided them into major discrepancy (including change of diagnosis of sarcoma to benign or other histological entity that could potentially change the treatment plan) or minor discrepancy (like mild change in grade or histopathological diagnosis not affecting the treatment plan). Results: There were 149 patients registered with median age of 36 years (14-77 years) and 93 patients (62.4%) were males. 85(57%) patients had localized disease. Most common subtypes were synovial sarcoma 16%, liposarcoma 9%, soft tissue ewings sarcoma 9%, MPNST 9%, leiomyosarcoma 8%, pleomorphic undifferentiated sarcoma 8% etc. Of 149 patients, 42 had not been worked up outside and thus comparison was not possible while 4 patients couldn’t retrieve blocks and repeat biopsy could not be performed. Of 97 patients (biopsy = 84, FNAC = 13) who had diagnosis from outside, 37% had major discrepancy and 24% had minor discrepancy compared with our biopsy review. Major discrepancy was more in non extremity than extremity STS (p = 0.003). Conclusions: Pathological diagnosis of more than half of patients referred from outside was discordant with respect to diagnosis of our centre with major implications on 37%. We believe this is due to lack of sarcoma pathology experts and virtually non-existent multidisciplinary clinics in set up outside tertiary care centres.
