Paraneoplastic syndrome (PNS) is the rare manifestation of malignancy which presents as remote systemic features unrelated to direct tumour involvement. Often PNS can be the only presenting symptom of the cancer and may warrant search for underlying malignancy. Immune response against malignant cells sometimes cross reacts and destroys the normal cells. PNS can manifest at any point of time in course of malignancy, either it may presage diagnosis, or at relapse settings. Successful treatment of the malignancy is the key in managing PNS. Autoimmune haemolytic anaemia (AIHA) is a common presentation of haematological malignancy, but rarely reported with malignant solid tumours. We, hereby, illustrate a rare association of AIHA as PNS in a case of testicular non-seminomatous germ cell tumour and its management along with review of literature. To the best of our knowledge, this is the first such a case to be reported in the literature.

Colorectal cancer (CRC) continues to be one of the common causes of cancer-related deaths. A significant proportion of surgically cured CRC patients’ relapse and if these recurrences are not resectable, they carry a poor prognosis. Despite advances in cancer treatment with targeted monoclonal antibodies, only minority benefit. At present, tissue biopsy, imaging and serum tumour markers are standard of care in the management. There is a constant need for novel biomarkers to improve risk stratification, pickup recurrences early and selection of therapy. Cellular contents of cancer cells, including their DNA, are continuously shed into circulation. This non-invasive blood-based genotyping of circulating tumour DNA (ctDNA) appears to provide genetic information similar to tumour tissue molecular profiling. Besides, ctDNA can be quantified and levels may be used to assess tumour burden. Here, we review several emerging clinical applications of ctDNA in parallel to the standard of care to improve the management of CRC.

Aims We compared the immune response evaluation criteria in solid tumors (iRECIST) with immune adaptive positron emission tomography response criteria in solid tumors (imPERCIST) in lung cancer patients treated with nivolumab. Materials and Methods Twenty lung cancer patients underwent fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) scan at baseline (PET-0), after four cycles (PET-1) and six to eight cycles (PET-2) of nivolumab were included. Kappa coefficient (k) was derived to see the level of agreement in two response criteria. Progression-free survival (PFS) curves were computed by the Kaplan–Meier method and compared with the Log Rank test. Univariate and multivariate regression for the percentage change in the sum of diameters (SoD), standard uptake value maximum (SUVmax), sum of metabolic tumor volume (SoMTV), and sum of total lesion glycolysis (SoTLG) was computed. A p-value less than 0.05 was considered significant. Results Kappa coefficient showed a substantial level of agreement (k 0.769) in two response criteria. Mean PFS in partial response, stable disease, and progressive disease (PD) patients in iRECIST and imPERCIST was 27.3, 17.7, 4.2, and 23.3, 18.8, 3.8 months, respectively. The Kaplan–Meier method with the log rank test showed a significant difference in PFS on intracomparison within both criteria; however, it was not significant on intercomparison. On univariate analysis, the percentage change in SoD, SoMTV, SoTLG was significant. However, on multivariate analysis, only percentage change in SoD was a significant predictor. Conclusions We concluded that imPERCIST was equally effective as currently recommended criteria iRECIST for response evaluation of nivolumab in lung cancer patients.

Objective To evaluate MGMT gene positivity is associated with better survival in patients diagnosed with brain tumor World Health Organization (WHO) grades III and IV Material and Methods Single-institute restrospective study. A total of 80 patients were enrolled, all underwent surgery either total or subtotal excision of the tumor and MGMT gene testing on tumor tissue by RT-PCR. All received adjuvant radiation (60 Gy/30 fractions, 5 fractions/week) with concurrent temozolomide (75 mg/m2), followed by 12 cycles of adjuvant temozolomide (150 mg/m2 1st cycle followed by 200 mg/m2) with regular follow-up. Results A total of 80 patients, 75 underwent subtotal excision, 27 were WHO grade III vs. 48 WHO grade IV. Five underwent total excision 1 was WHO grade III vs. 4 WHO grade IV. The median PFS and OS in five patients in total excision in grade III patient was 9.0 and 20 compared with Grade IV, where the median PFS and OS was 8.8 and 17.8 months. Out of 75 patients in the subtotal group median PFS and OS, respectively, in Grade III group was 9.1 and 19.3 and, WHO grade IV with median PFS of 8.8 and OS of 18.8. Conclusion MGMT gene positivity is a prognostic factor in grade III and IV brain tumor.

Introduction: The cure of corneal blindness requires manifold increase in the rate of eye donation. The present study was undertaken to assess the knowledge and attitude about eye donation among medical students. A secondary objective of the study was to assess the impact of knowledge of eye donation after studying ophthalmology among the final year students of the MBBS (Bachelor of Medicine Bachelor of Surgery) graduation course. Aim: To assess knowledge and attitude about eye donation among first, second and final year medical students. Also, to assess the impact of studying ‘Ophthalmology’ on their knowledge. Materials and Methods: A cross-sectional study was conducted by collecting information on a predesigned, structured questionnaire on ‘Google forms’ and sending a soft copy to 601 students of two medical colleges i.e, GGS Medical College, Faridkot and Dayanand Medical College, Ludhiana, Punjab, India, by email, from March 2019 to April 2019. There were questions about awareness and source of information about eye donation in medical students, knowledge of criteria, and willingness to donate eyes. Responses were accepted till a period of seven days. Students were divided into two groups; group A (n=320 students) with 165 students in first professional year and 155 in second professional year, who had not studied Ophthalmology. Group B (n=281 students) with 142 students in final (part I) professional year and 155 in final (part II) professional year, who had/were studying Ophthalmology. Results were analysed and compared using Chi-square test. Results: Out of 601 students, 527 responded (272 of group A and 255 of group B). The results on knowledge and willingness to donate eyes were quite encouraging. Most of the questions were answered by more than 400 students. Majority of students cited teachers/friends as their source of knowledge. However, there was a saw significant gaps in knowledge in the students, specially before reading Ophthalmology (p-value

Immediate extubation is integral constituent of enhance recovery protocols. Purpose of this study was to examine success rates and safety of protocolized immediate extubation in pediatric living donor liver transplant recipients and to find out factors associated with non-immediate extubation in operation room.We performed retrospective analysis for data of small (≤20 kg) pediatric patients transplanted between 2017 and 2019 (protocolized duration) and compared with data of transplants done between 2014 and 2016 (non-protocolized duration). Further, we compared data during each time duration between immediate extubation and non-immediate extubation group to find risk factors in that particular duration.Immediate extubation rates were significantly higher during protocolized duration compared with non-protocolized duration (85.52% vs. 48.29%, p .001). Reintubation rates decreased during protocolized duration (10.9% vs. 4.6%). Hospital stays (20.47 ± 7.06 vs. 27.8 ± 6.2 days, p .001) and mortality (13.2% vs. 28%, p = .04) were significantly decreased in protocolized duration. Higher age (OR: 2.85, 95% CI 1.22-6.67, p = .02), weight 10 (OR: 4.37, 95% CI 1.16-16.46, p = .029) and high vasopressor support (OR: 32, 95% CI 6.4-160.13, p .001) found as significant predictors of non-immediate extubation however only high vasopressor support found to be independent predictor during protocolized duration.Outcomes in pediatric transplants can be optimized by immediate extubation in majority of cases when protocolized as part of policy.

The molecular pathogenesis of breast cancer (BC), the second most common cancer, varies significantly between sexes, with minimal data in the transgender population. The overall prevalence of BC in transgenders is estimated to be 0.02%. Besides experiencing social disparities, transgenders have to face a lot of discrimination in the healthcare system. Adversities faced, along with the urge to identify with physical attributes to the gender felt by them, forces transgenders to use non-prescribed hormones. Gender affirming hormone therapy (GAHT) is a key feature of transition-related care, rehabbing mental health, and the quality of life of transgenders, but at the expense of their health. Studies have reported that GAHT is associated with severe health conditions such as cancer in transgenders. Estrogens and testosterone are associated with a moderate risk of developing BC. The types of BC diagnosed in transgenders after cross-sex hormone therapy include invasive ductal and neuroendocrine carcinoma, in addition to tubular adenocarcinoma. Although diagnosed at an age earlier compared with ciswomen, BC screening recommendations for transgenders are the same as for ciswomen. This review studies in detail the types of transgenders, their characteristics, different types of breast cancers associated, issues faced while treatment, and their best possible solutions. We also hope to have well-designed research in the future, which will fill the existing gaps in knowledge and provide scientific insight into the transgender population and issues related to their health. There are no international guidelines on screening and management of transgender patients but it appears that breast screening before cosmetic mastectomy, exposure to hormonal therapy for more than 5 years, and as per natal women screening guidelines should be offered to the patient with detailed discussion on the harms and benefits of the same.

Posttreatment detection of residual/recurrence disease in the head and neck cancers is not an easy task. Treatment induces changes create difficulties in diagnosis on conventional imaging (computed tomography [CT], magnetic resonance imaging) as well as macroscopic inspection (direct laryngoscopy). Hence, we evaluate the diagnostic performance of contract-enhanced F-18 fluorodeoxyglucose positron emission tomography (FDG PET)/CT in restaging of laryngeal carcinoma Postchemotherapy-surgery and/or radiation therapy. We retrospectively analyzed patients of carcinoma larynx (n = 100) who has completed treatment and were referred for FDG PET/CT. Two reviewers performed image analysis to determine recurrence at primary site and/lymph nodes and distant metastases. Receiver operating characteristic (ROC) was used to determine the maximum standardized uptake value (SUVmax) cut off for disease detection. Histopathological examination and clinical or imaging follow-up were taken as gold standard for recurrence. One hundred laryngeal carcinoma patients with mean age of 57.2 years (range of 40–76) were included in the present study. Among the 100 patients, 96 were male and remaining 4 were female. The average interval between completion of treatment and FDG PET/CT scan was 8.5 months (minimum 6 months). Of the 100 patients, FDG PET/CT detected FDG avid lesions in 66 patients. Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of FDG PET/CT for residual/recurrence disease detection was 90.3%, 73.7%, 84.8%, 82.3%, and 84.0%, respectively (P < 0.05). In addition, in 10 patients, metachronous primaries were detected (lung-4, thyroid-2, tongue, colon, esophagus, and lymphoma-one each). On ROC curve analysis, SUVmax >6.1 had sensitivity and specificity of 80.6% and 94.7% respectively for detection of recurrent/metastatic disease. FDG PET/CT demonstrates high diagnostic accuracy for detection of residual/recurrent disease in treated laryngeal cancer patients and our findings suggest that this imaging modality should be the first-line diagnostic investigation in this cohort of patients.

Here we present a rare case of spontaneous pneumomediastinum complicated with pneumorrhachis (PR) in a young man who is a known case of carcinoma rectosigmoid region. Our young male was diagnosed with novel coronavirus disease 2019 (COVID-19) and remained asymptomatic for any respiratory complaints. Though an association of pneumomediastinum has been reported in COVID 19 patients, to the best of our knowledge, this is the first report of PR in a COVID-19 oncological case. The role of a radiologist is to identify this condition as cases reported earlier may have serious neurological consequences. Pursuing the cause can be a diagnostic challenge but it reaps the clinical benefit in the appropriate management.

OBJECTIVE The aim of this study was to evaluate the diagnostic performance of contrast-enhanced F-18 fluoro-2-deoxyglucose (F-18 FDG) PET/computed tomography (CT) in restaging of tongue carcinoma. MATERIAL AND METHODS Retrospectively analysis of carcinoma tongue patients (n = 110) who were treated and referred for FDG PET/CT. Histopathological examination and clinical or imaging follow-up were taken as gold standard. RESULTS Of 110 patients, FDG PET/CT detected FDG avid lesions in 69 (62.7%) patients. Sensitivity, specificity and diagnostic accuracy of FDG PET/CT were 92.9%, 90.0% and 91.8%, respectively, for residual/recurrence disease detection (P < 0.05). Additionally, in six patients, metachronous primaries were also detected [lung (4), esophagus and lymphoma (1) each]. The mean maximum standardized uptake value (SUVmax) with 95% confidence interval for primary site recurrence, regional lymph nodes and metastatic lesions was 11.51 (9.53-13.48), 69 (62.7%) (7.88-11.48) and 8.94 (3.11-14.76), respectively. CONCLUSION FDG PET/CT demonstrates high diagnostic accuracy for detection of residual/recurrent disease in treated tongue cancer patients and PET/CT should be considered as first-line diagnostic investigation in these patients.

Spinal extradural arteriovenous fistulas are rare vascular lesion which are defined as abnormal direct connection between an artery or arteries and the extradural venous plexus within the spinal canal and/or intravertebral foramen. These lesions with exclusive extradural venous drainage are even rarer. Because of the limited cases the natural history, demography and treatment understanding of these are limited. Endovascular treatment remains the mainstay of treatment for these lesions. This case and its management are thus presented for its rarity.

Objective The aim of this study is to investigate the effects of gemcitabine maintenance on progression-free survival (PFS) in patients with metastatic gallbladder cancer (GBC). Materials and Methods Sixty patients with unresectable or metastatic GBC having ongoing response to treatment with initial six cycles of gemcitabine and a platinum-based doublet chemotherapy were prospectively randomized on day 21 of the 6th cycle in 1:1 fashion to receive either maintenance gemcitabine 1 g/m2 intravenously on day 1 and day 8 of three weekly cycle or observation. Survival analysis was performed using the Kaplan–Meier method and comparisons by the log-rank test. A p-value < 0.05 was considered as statistically significant. Results Of 60 patients, a total of 56 were available for final analysis. The median PFS was 4.7 months (3.1–6.3) in gemcitabine arm and 2.6 months (2.4–2.8) in observation arm, hazard ratio (HR) 0.196 (95% confidence interval [CI]: 0.1–0.39), p < 0.001. Median overall survival in gemcitabine arm was 12.4 months (9.15–15.6) as opposed to 9.9 months (8.29–11.5) in observation arm, HR 0.76 (95% CI: 0.43–1.35), p = 0.354. The grade 3 or 4 side effects in maintenance arm were transaminitis (17.9%), thrombocytopenia (17.8%), neutropenia (14.2%), and febrile neutropenia (7.1%). Conclusions Maintenance gemcitabine therapy in unresectable/metastatic GBC patients responding to first-line gemcitabine and platinum treatment contributes to increase PFS with minimal and manageable side effects.

Background: Diagnosis of respiratory viral pathogens can lead to therapeutic changes, improvement in infection control practices and reduction in use of antibiotics. Methods: This is a retrospective study which looked into the case records of patients (June 2020-Dec 2021) who were diagnosed with a respiratory viral infection. Demographic, clinical and antibiotic prescription patterns of these patients were studied. Inter-group analysis was done between antibiotic de-escalation cohort and non-descalation cohort. Results: Total of 57 patients were identified with median age of 40 years (range: 3-68), out of which 38 (66.6%) were males. Hematological malignancies were present in 45 (78.9%) of patients, whereas 14 (24.5%) patients were stem cell transplant recipients. Severe neutropenia was seen in 32 (56.1%) patients with median duration of neutropenia of 7 (range 5-20) days. RSV (36.8%) was the most common virus detected followed by rhinovirus (19.3%) and influenza (19.3%). Antibiotic de-escalation was done in 33 (57.8%) of patients and in 13 (22.8%) bacterial co-infection was diagnosed. More than 3/4th patients were shifted to isolation and nearly 9000 INR per patient were saved by de-escalation of antibiotics. Death occurred in 4 (7.0%) patients. On inter-group analysis, non-de-escalation cohort had longer length of stay (10 vs 3 days; p =0.005), no antibiotic cost reduction (0 vs 9620; p=0.0003), higher mortality (16.6% vs 0%; p =0.01) & higher rhinovirus detection rates (41.6% vs 3%; p=0.0002).Conclusion: Diagnosis of respiratory viral infection helped in improving antibiotic stewardship and infection control practices.

Background: Cerebral vasospasm is a major cause of morbidity and mortality in patients with subarachnoid hemorrhage. Vasospasm is managed with triple H and vasodilators but sometimes, patients do not respond. Intra-arterial vasodilator infusion has been shown to improve outcome in such patients. In this study, we try to evaluate the efficacy of intra-arterial nimodipine therapy in 43 patients of post-aneurysmal subarachnoid hemorrhage refractory cerebral vasospasm. Methods: It is a prospective observational study of a group of 43 patients presenting with refractory cerebral vasospasm as per the inclusion criteria. Pre-procedure neurological assessment and Transcranial Doppler (TCD) monitoring were done. Endovascular spasmolysis was conducted and post-operative morbidity and outcomes were noted. Follow up of the patients was done at the time of discharge and at 6 months according to the Modified Rankin Scale and NCCT head. Results: Most of the patients developing refractory cerebral vasospasm belonged to Hunt and Hess Grade 2 and 3 and Fisher grade 3 and 4. 87.5% of the patients showed clinical recovery following endovascular spasmolysis and 58% of the patients showed complete angiographic recovery. Outcome after 6 months was good in 76%, moderate in 12% and poor in 12% patients. NCCT head showed no infarct in 58%, minor infarct in 28% and major vascular territorial infarct in 14% patients. Conclusions: Intra-arterial nimodipine infusion is a safe and effective therapy with minimum risk of complications if adhered to standard endovascular practice. By timely intervention, major ischemic insult to the brain can be averted, thereby significantly improving the prognosis.

Syphilis has a wide variety of ocular presentations such as anterior or posterior uveitis, chorioretinitis, retinal vasculitis, retinitis, perineuritis, papillitis, retrobulbar neuritis, optic atrophy and optic nerve gumma. Therefore, it is recommended to test every patient with ocular inflammation for syphilis. It is, however, a relatively rare cause of uveitis in HIV disease. A few studies suggested that HIV contributes to the ocular manifestations of syphilis and HIV co-infection in approximately 30%. Acute syphilitic posterior placoid chorioretinopathy is a rare ocular manifestation in immune-competent patients characterised by the development of a deposit in the outer retina. We describe an unusual such presentation with hypopyon.

Primary gastric squamous cell carcinoma is a very rare presentation. Its pathogenesis is obscure, and the treatment strategy is largely unknown and controversial. We report a case of primary squamous cell carcinoma of the stomach with liver metastases in a 66-year-old man. The patient presented with a 2-month history of abdominal pain, vomiting, hematemesis, and weight loss. Endoscopic examination revealed large ulceroproliferative growth in body of stomach. Integrated PET CT (positron emission tomography computed tomography) scan revealed metabolically active nodular wall thickening involving body of stomach with liver metastases. Multiple biopsies of the lesions revealed squamous cell carcinoma of the stomach. The patient was started on palliative chemotherapy and is presently in partial response to treatment. He is tolerating treatment with no major side effects.

Purpose Role of diffusion-weighted (DW) MR imaging in differentiating residual or recurrent neck malignancies from postoperative/post-radiation changes with histopathological correlation and comparison with PET-CT. Methods and materials Prospective observational study for a period of 1 year in 62 post-radiation/post-operative patients suspected to have residual/recurrent tumors of neck with lesion diameter more than 5 mm measured on MRI. Results Mean ADC for recurrent/residual tumors: 1.008 ± 0.220 × 10−3 mm2/s - significantly lower than mean ADC value for post-treatment changes of 1.69 ± 0.40 × 10−3 mm2/s (p Conclusion DW MRI is a promising non-invasive MRI technique used to differentiate recurrent/residual head and neck malignancies from posttreatment changes based on ADC values. DWI offers advantage as it has a short scanning time and can be safely added to standard MRI protocol with minimum patient discomfort. Complementary use of DWI and PET/CT imaging may increase diagnostic confidence for differentiating recurrent disease from radiation therapy-induced changes after 6–12 months in posttreatment cases.

Background Early oral cavity cancer has good prognosis but recurrence in them is still not uncommon. There is no general consensus on the prognostic factors and adjuvant therapy that would have a significant impact on survival. Methods A retrospective analysis of early oral cavity cancer patients during the time period 2009-2017. The data regarding demographics, histopathological features, and recurrence patterns were collected and analyzed. Results Depth of invasion (DOI) was the most important prognostic factor among all the factors analyzed. Further analysis showed that addition of adjuvant radiotherapy for patients with DOI >5 mm did not show survival benefits (P = .73). Another subset analysis of patients with DOI >10 mm also did not show any survival advantage with adjuvant therapy P = .24. Conclusion There is no benefit of adding adjuvant RT in patients with DOI > 5 mm or in patients who were upstaged to T3 based only on DOI.

Poly (ADP-ribose) polymerase (PARP) inhibitors are a unique class of therapeutic agents that focus on tumors with deficiencies in the homologous recombination DNA repair mechanism. Genomic instability outlines high-grade serous ovarian cancer, with 50% of all tumors displaying defects in the important DNA repair mechanism of homologous recombination. Earlier research studies have demonstrated considerable efficiency for PARP inhibitors in patients with germ line breast-related cancer antigens 1 and 2 (BRCA-1/BRCA-2) mutations. It has also been observed that BRCA wild-type patients with other defects in the homologous recombination repair mechanism get benefited from this therapy. Companion homologous recombination deficiency (HRD) scores are being developed to guide the selection of patients that are most likely to benefit from PARP inhibition. The selection of PARP inhibitor is mainly dependent upon the number of prior therapies and the presence of a BRCA mutation or HRD. The identification of cases which are most likely to get benefited from PARP inhibitor therapy in view of HRD and other biomarker assessments is still challenging. The purpose of this review is to focus and describe the current evidences for PARP inhibitors in ovarian malignancy, their mechanism of action, and the outstanding issues, including the rate of long-term toxicities and the evolving resistance.

The combination of cyclin dependent kinase 4/6 inhibitors with endocrine therapy is the standard therapy in hormone receptor positive HER-2 negative metastatic breast cancer (HR+/HER2− MBC). Several randomized trials have shown the benefits of this combination, however, real world evidence in the Indian patients is warranted. The present study reports the largest real world multicentric data from Indian population on the use of Palbociclib in HR+/HER2− MBC. A multicentric study on the HR+/HER2− MBC patients who received palbociclib with hormonal agent (Aromatase inhibitors/Fulvestrant) between February 2017 and May 2020 was conducted. Clinical and demographic information and survival data was retrieved from the Hospital medical records. Among a total of 188 patients, 57% patients were premenopausal and 17% patients had bone only disease. Altogether, 115 (61%) patients received palbociclib with Aromatase inhibitors in the first line whereas 73 (39%) patients received it in the second line with Fulvestrant. The median follow up period with advanced disease was 13 months. The median progression free survival in the first line and second line was 20.2 months and 12 months, respectively (p-value

Background Continuous Renal Replacement Therapy (CRRT) is often used to support the intraoperative course during liver transplantation (LT) for patients with HRS. However, the use of intraoperative CRRT (IOCRRT) is not without its problems. Living donor liver transplantation (LDLT) is a planned operation and is possible without IOCRRT as the recipient can be optimized. Aim To study the peritransplant outcomes of patients with CLD and HRS undergoing LT without IOCRRT. Methods Analysis of LT program database for perioperative outcomes in patients with HRS from Feb 2017 to Dec 2018. Results 87/363 (23.9%) adult LDLT patients had HRS, of whom 31 (35.6%) did not respond (NR) to standard medical therapy (SMT) prior to LT. Modified perioperative protocol enabled the NR patients (who were sicker and in persistent renal failure) to undergo LT without IOCRRT. Postoperative renal dysfunction was similar (2 in NR and 2 in R) at 1 year. Post-LT survival was also not different at one month (83.87% in NR and 87.5% in R [p = .640]) and at 1 year (77% in NR vs 80.4% in non-responders [p = .709]). Conclusion IOCRRT can be avoided in HRS patients undergoing LDLT without compromising their outcomes (post-LT survival and RD), even in patients who have not responded to SMT, preoperatively.

BACKGROUND: The Information Technology (IT) industry of India has proved its capabilities in delivering both on- and off-shore services to clients globally over the years. However, the technological advances and innovations taking place at the global level not only present a whole new range of growth prospects, but also challenges for this highly competitive industry. Moreover, the IT sector of India also witnessed the economic recession in 2008, which had an adverse impact on the prospects of this industry. In this scenario, it is imperative for Indian IT companies not only to maintain their focus on increasing their technical efficiencies, but also to deal with the increased competition emanating from the Asia Pacific region. OBJECTIVE: This study aimed to estimate the relative efficiency of the top 18 selected Indian IT software service companies in order to determine benchmarks, output slacks and target settings. METHODS: Data envelopment analysis has been used for achieving the stated objective. RESULTS: The paper found mixed trends in efficiency. The top five IT companies exhibited higher efficiency as compared to the rest of the selected IT companies. Tata Consultancy Services, HCL Technologies Ltd. and Tech Mahindra Ltd. are more efficient while Infosys Ltd. and Mphasis have lower efficiency. CONCLUSION: The inefficient companies have to increase their workers’ productivity to become more efficient, and have to catch-up and follow the best practices of the benchmark company HCL.

The recent outbreak of COVID‐19 has brought elective surgeries including liver transplantation to a standstill. The concerns in Living Donor Liver Transplant (LDLT) were that immunosuppressed recipients and healthy donors would be exposed to nosocomial SARS‐ CoV‐2 infection.1 However, as patients began to suffer and die, Liver Transplant Society of India (LTSI) revised its guidelines 2 and allowed LDLT for those who were very sick, or had just recovered from a life threatening decompensation (high MELD/ CTP score) or had malignancy. Over 90 % of transplants in India are from live donors as we have a very low donation rate.

Parotid gland is a rare site of metastasis from gastrointestinal (GI) tract primary cancer. Here, we present an interesting case report of parotid metastasis from unknown primary with probable lower GI tract as a primary site of cancer, with a normal colonoscopy and upper GI endoscopy. This case report highlights the importance of immunohistochemistry in taking treatment decisions during dilemmatic situations.

Background & objectives: Slums are considered as hotspots of tuberculosis (TB). The study of genetic diversity and drug susceptibility profile of Mycobacterium tuberculosis (MTB) will help understand the transmission dynamics and can be used for better prevention and control of the disease. The aim of this study was to determine the drug susceptibility profiles and genetic diversity using the random amplified polymorphic DNA (RAPD) and mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU VNTR) of MTB isolates from sputum samples of pulmonary TB patients residing in the two slums of Jaipur city in Rajasthan, India. Methods: Sputum samples collected from pulmonary TB patients, their contacts and suspects during 2010-2012 were processed for microscopy and mycobacterial culture. Drug susceptibility testing was done by one per cent indirect proportion method on Lowenstein–Jensen medium for first-line anti-TB drugs rifampicin, isoniazid, ethambutol and streptomycin. MTB DNA was extracted by physicochemical method, and DNA fingerprinting was done by RAPD and MIRU VNTR analysis. Results: Among 175 sputum samples collected, 75 were positive (43.8%) for acid-fast bacilli, 83 for MTB culture and four were contaminated. Fifty two isolates (62.7%) were fully sensitive to four drugs, and five (6%) were multidrug resistant (MDR). RAPD analysis of 81 isolates revealed six clusters containing 23 (28.4%) isolates, and 58 (71.6%) were unique. MIRU VNTR analysis clustered 20 (24.7%) isolates, and 61 (75.3%) were unique. Interpretation & conclusions: About 62.7 per cent isolates from the sputum samples from slum areas were sensitive to four drugs; six per cent of isolates were MDR. Poly-resistance other than MDR was high (16%). About one-fourth isolates were clustered by either method. RAPD was rapid, less expensive but had low reproducibility. MIRU VNTR analysis could identify to greater extent the epidemiological link in the population studied.

Aims and Objectives: During course of radiation therapy, anatomical variations occur risking overdose of parotid gland. We tried to quantify volume of parotid gland and mean dose to parotid gland after every 10 fractions (#). Materials and Methods: We conducted the prospective study from July 2016 to May 2017 in 25 patients of early-stage oropharyngeal carcinoma. Patients had Karnofsy Performance Score of 80–100, median age was 54 years, and 18 patients were males. Patients were planned with intensity-modulated radiation therapy planning with dose as 66 Gy/30# to planning target volume (PTV) including primary and 54 Gy/30# to PTV-nodal including elective neck irradiation. After each 10#, replanning was done, and variations in parotid volume were studied including Dmean(mean dose to parotids) and D50(the dose delivered to 50% of volume). Other tumor characteristic like PTV of primary was also assessed and minimum PTV volume covered by 95% isodose line was kept as 95%. Results: Average parotid volumes decreased by the mean value of 10% and 6% for the left and right parotids, respectively, and PTV of primary target decreased by mean of 13%. The difference in Dmeandoses to parotid glands was 32% and 42% and difference in D50dose was 30% and 35% on the left and right side, respectively. Conclusions: The parotid volumes differ considerably during adaptive planning done after every ten fractions. These differences in parotid volumes and doses received to parotid glands play a significant role in the risk of xerostomia observed during later follow-up.

Background and Aims: Viscoelastic haemostatic assays (VHA) namely Thromboelastogram (TEG) and Rotational thromboelastometry (ROTEM) are used for global assessment of coagulopathy and guiding transfusion during living donor liver transplant (LDLT).We conducted a study to compare the interchangeability of the values obtained from these devices in patients with End stage liver disease (ESLD) undergoing LDLT. Methods: In 76 patients undergoing LDLT, ROTEM and TEG were performed and assessed for interchangeability using Spearman Correlation. The direction and strength of correlation between equivalent parameters was calculated using Inter Class Correlation (ICC) and Bland Altman analysis. Results: The correlation ρ between CT (clotting time) of ROTEM and R of TEG was 0.16 (P = 0.19).The ICC was 0.15, with 95% confidence interval (CI) of -0.38-0.48 (P = 0.25).The ρ of CFT (ROTEM) with K (TEG) was 0.425 (P=

Objectives: To evaluate the role of apparent diffusion coefficient (ADC) values in assessing response after chemo-radiotherapy in cervix cancer and investigate the utility of ADC as a tool to identify residual disease, after the treatment completion. Methods: A prospective study was done in 100 patients with histopathologically proven cancer of uterine cervix who were classified as either complete response (CR) or residual disease posttreatment. MRI was done pretreatment and after 6 weeks post-treatment with chemo-radiation. 53 patients among the cohort also underwent a fluoro-deoxy glucose positron-emission computed tomography (FDG-PET CT). ADC values, change in ADC values, and metabolic activity obtained from FDG-PET CT were correlated with clinical outcome, and statistical analysis was done to determine the better tool for assessing response evaluation between ADC and PET-CT. Results: Residual lesions have notably lower ADC value than that of posttreatment changes. The mean ADC values of residual tumors: 1.26 ± 0.238 × 10−3 mm2/s and mean ADC values of lesions due to posttreatment changes: 1.540 ± 0.218 × 10−3 mm2/s (statistically significant difference between malignant and posttreatment lesions, P < 0.05). ADC has 67% sensitivity, 83% specificity, 35% positive predictive values (PPV), 95% negative predictive values (NPV), and 81% accuracy in differentiating residual disease from post treatment changes. PPV, NPV, sensitivity, and specificity with PET-CT were 93%, 89%, 98%, and 73%, respectively. PPV, NPV, sensitivity, and specificity of contrast MRI were 16%, 91%, 58%, and 59%, respectively. Conclusion: Diffusion imaging differentiates residual cervix malignancies from post treatment changes based on ADC values and can be a promising and evocative biomarker. Complimentary use of ADC and PET/CT may increase diagnostic confidence.

Breast cancer is the commonest and the lead cause of cancer deaths worldwide, which accounts for 23% of total cancer load and 14% of cancer-related mortalities. Preinvasive lesions of the breast rank fourth after invasive breast, lung, and colorectal cancer. These lesions are mainly grouped into lobular and ductal in situ carcinomas. This chapter discusses the various modalities used for detection of preinvasive breast lesion including imaging and biopsy of the lesion. This chapter also elaborates on the recent trends in the treatment of the same.
