Abstract
Globally, peripheral T-cell lymphomas (PTCLs) constitute about 12% of all non-Hodgkin lymphomas, of which the unspecified category is the most common subtype (30%). Mostly, the unspecified category shows a diffuse pattern of involvement in the lymph nodes. However, rarely, they may show a follicular/nodular pattern mimicking a follicular lymphoma. We report a case of a follicular variant of PTCL, not otherwise specified. This case displayed a striking nodular/follicular pattern with an admixture of small (centrocyte-like) and large (centroblast-like) cells, thus mimicking a follicular lymphoma. The neoplastic cells were strongly positive for both CD3 and CD20. In addition, they were positive for pan T-cell markers and PD-1. T-cell receptor gene rearrangement studies highlighted a monoclonal T-cell population. Even though this variant of PTCL is very rare, it is important to keep it as a differential for the lymphomas exhibiting nodular pattern.

Abstract
CONTEXT In view of low incidence of contralateral nodal metastasis and increase in the morbidity, the opposite neck is not routinely addressed. However, contralateral nodal metastasis is seen frequently in a certain group of patients. Identifying those factors associated with higher chances of contralateral nodal metastasis may help in optimizing the treatment. AIMS The aim of this study was to identify prognostic factors associated with contralateral nodal metastasis in cases of buccal mucosa cancers. SETTINGS AND DESIGN A retrospective audit of 125 patients with squamous cell carcinoma of buccal mucosa at a tertiary cancer center. SUBJECTS AND METHODS Those cases in which lesions were reaching or crossing midline were included in this study. All cases underwent surgery as primary modality of treatment and had bilateral neck dissection. STATISTICAL ANALYSIS USED Chi-square test is used for evaluating the variables predicting contralateral nodal metastasis. Finally, a multivariate analysis was performed using binomial logistic regression to identify those variables that were independently associated with the risk of contralateral nodal metastasis. RESULTS Among 125 patients, 53 cases were node negative. Ipsilateral nodal metastasis was seen in 44/125 (35.2%) patients, 26/125 (20.8%) had bilateral neck node metastasis, and 2/125 (1.6%) had isolated contralateral nodal metastasis. Among these 28 patients with contralateral nodal metastasis, 26 patients had ipsilateral nodal metastasis. Ipsilateral nodal metastasis and skin involvement were independently predictive of contralateral nodal metastasis. CONCLUSIONS Contralateral nodal metastasis in the absence of ipsilateral nodal metastasis is very rare and frozen section of ipsilateral neck dissection specimen can be an important pointer for addressing contralateral neck.

Abstract
Abstract
Background: Increased stromal tumor infiltrating lymphocytes (TILs) are predictive and prognostic for improved outcomes from neoadjuvant or adjuvant chemotherapy in triple negative breast cancer. Increased tumor mutational burden may promote neoantigens causing immune system upregulation. Microsatellite instability in gastrointestinal cancer predicts for response to checkpoint inhibition and is associated with inherited cancer predisposition. The immune system response in BRCA mutated breast cancer has not been described. The purpose of this study is to assess tumor infiltrating immune cells in early stage breast cancer patients with and without BRCA gene mutations.
Methods: We retrospectively investigated 124 early stage breast cancer patients with BRCA mutations (n=62, BRCA+) and without BRCA mutations (n=62, BRCA WT). The %TILs was measured manually by H&E. Our control group consisted of age, stage, and receptor status matched early stage untreated breast cancer patients who were deemed BRCA WT by extended gene panel testing or were negative for BRCA 1/2 and had a posttest probability of harboring an autosomal dominant mutated gene of ≤ 1% using the Bayes-Mendel algorithm. We used a two-sample binomial arcsin approximation to detect a 20% difference in TILs between cohorts to attain 80% power with a one-side alpha of 0.05. Wilcoxon Rank-Sums test was used to compare differences in the central tendencies for continuous variables. We used the Nanostring PanCancer immune profiling panel to immunophenotype a portion of the BRCA+ and BRCA WT cohorts and used nSolver for quality control, normalization, and bioinformatics analyses.
Results: Here we report TILs from the first 21 patients of our study. Thirteen patients harbored BRCA mutations and eight patients did not. All patients were HER2 negative. Eight (61%) and four (50%) patients were hormone receptor positive (HR+) in the BRCA+ and BRCA WT cohorts, respectively. Median %TILs were not significantly different between the BRCA+ (15, range 0-70) and BRCA WT (17.5, range 5-60; p=0.7) groups. Median %TILs in the HR+/BRCA+ (12.5, range 0-50) and HR-/BRCA+ (15, range 5-70) cohorts were not statistically different when compared to HR+/BRCA WT (10, range 5-15; p=0.4) and HR-/BRCA WT (30, range 20-60; p=0.2) cohorts, respectively. There were 2 patients with lymphocyte predominant breast cancer (n=1, HR-/BRCA+; n=1, HR-/BRCA WT).
Conclusions: This is the first study to characterize TILs and a tumor immune microenvironment phenotype in early stage breast cancer patients with BRCA mutations. These results suggest harboring a BRCA mutation is not associated with increased TILs in early stage untreated breast cancer patients. This conclusion stayed true regardless of hormone receptor status. However, a trend of decreased TILs was seen in HR-/BRCA+ patients when compared to those with HR-/BRCA WT disease. Moreover, the median and range of TILs were higher in the HR+/BRCA+ group compared to the HR+/BRCA WT group. This suggests increased TILs may exist in some HR+ patients with a BRCA mutation. Further investigation of TILs and immune profiling of early stage untreated breast cancer patients with and without BRCA mutations is warranted.

Abstract
INTRODUCTION Human Immunodeficiency Virus (HIV), Hepatitis B virus (HBV) and Hepatitis C virus (HCV) are the most common occupationally acquired infections amongst the healthcare workers (HCWs) with critically ill patients attending the emergency department being the most common source of occupationally acquired infections. Therefore, the present study was conducted at a 165 bedded level-1 trauma centre of India to ascertain the seroprevalence rate of HIV, HBV and HCV; and thus the risk associated with the occupational exposure in a busy emergency setting of the developing world. METHODOLOGY A retrospective, 7 years study (2007-2013) was carried out at the JPNA Trauma Centre of the 2,500 bedded All India Institute of Medical Sciences, New Delhi. Records of all patients whose serum samples were sent to the laboratory for viral markers testing were obtained and those falling in the red area were included. RESULTS A total of 11,630 patients were received in the red area; and samples from 7,650 patients were sent for testing. Seropositivity of HIV, HBV and HCV in these samples was 0.28%, 3.4% and 0.9% respectively. The number of samples received was lesser than the total number of patients received in the red area. CONCLUSION Adopting Standard Precautions (SP) can be used as an easy method to decrease the risk of occupationally acquired infections.

Abstract
Primary non-Hodgkin lymphomas of the oral region are rare, accounting for 3–5% of all malignant lesions. Of these, peripheral T-cell lymphomas (PTCLs) are extremely rare with only a few cases reported in literature. We describe a case of 50-year-old female who presented with an indurated lesion on the tongue. PTCL was diagnosed after immunohistochemical and T-cell receptor gene rearrangement analysis. Although PTCL of oral cavity is extremely rare, the possibility should always be considered in the differential diagnosis of T-lymphoid proliferations affecting this area.

Abstract
Despite advances in the diagnosis of prostate cancer over the past century, it remains a leading cause of cancer related death. A recent recommendation against screening has further complicated the diagnosis and management of this condition. It remains to be demonstrated if newer diagnostic modalities will have an impact on mortality rates. Most certainly, not all prostate cancers need to be diagnosed, and methods of accurately diagnosing those cancers that lead to death needs more work. In this review article, we describe the different techniques, approaches and diagnostic accuracies of the currently used biopsy methods.

Abstract
AIMS Endoplasmic reticulum (ER) stress exerts myocardial oxidative stress, apoptosis, and contractile anomalies, although the precise interplay between ER stress and apoptosis remains elusive. This study was designed to examine the impact of the cysteine-rich free radical scavenger metallothionein on ER stress-induced myocardial contractile defect and underlying mechanisms. METHODS AND RESULTS Wild-type friendly virus B and transgenic mice with cardiac-specific overexpression of metallothionein were challenged with the ER stress inducer tunicamycin (1 mg/kg, intraperitoneal, 48 h) prior to the assessment of myocardial function, oxidative stress, and apoptosis. Our results revealed that tunicamycin promoted cardiac remodeling (enlarged left ventricular end systolic/diastolic diameters with little changes in left ventricular wall thickness), suppressed fractional shortening and cardiomyocyte contractile function, elevated resting Ca(2+), decreased stimulated Ca(2+) release, prolonged intracellular Ca(2+) clearance, and downregulated sarco(endo)plasmic reticulum Ca(2+)-ATPase levels, the effects of which were negated by metallothionein. Treatment with tunicamycin caused cardiomyocyte mitochondrial injury, as evidenced by decreased mitochondrial membrane potential (∆Ѱm, assessed by JC-1 staining), the effect of which was negated by the antioxidant. Moreover, tunicamycin challenge dramatically facilitated myocardial apoptosis as manifested by increased Bax, caspase 9, and caspase 12 protein levels, as well as elevated caspase 3 activity. Interestingly, metallothionein transgene significantly alleviated tunicamycin-induced myocardial apoptosis. CONCLUSION Taken together, our data favor a beneficial effect of metallothionein against ER stress-induced cardiac dysfunction possibly associated with attenuation of myocardial apoptosis.

Abstract
To study the short-term functional outcomes of the endoscopic modified Lothrop procedure with well defined subjective and objective criteria. It's a retrospective cohort study with chart review carried out at a tertiary referral center. 31 patients with chronic frontal sinusitis who underwent endoscopic modified Lothrop's procedure with uncinate preservation during the period Jan 2011-2014 were followed up for a period of minimum 6 months. Assessment was done post-operatively based on subjective severity score and Kennedy's 5 point endoscopic criteria. Subjective improvement was seen in all symptoms whereas statistically significant improvement was found for the three parameters headache (p < 0.025), nose block (p < 0.03) and rhinorrhea (p < 0.05). Post operative nasal endoscopy revealed crusting and polypoidal mucosa in few patients which were managed conservatively. Asymptomatic narrowing of ostium seen in two patients. No complications were identified. The study illustrates the benefit obtained from endoscopic modified Lothrop's surgery in chronic frontal sinusitis refractory to medical treatment and standard endoscopic sinus surgery.

Abstract
Three histological subtypes of lymphomatoid papulosis (LyP), type A (histiocytic), type B (mycosis fungoides like) and type C (anaplastic large cell lymphoma like) are well recognized. Two new histological variants, type D (simulating an aggressive epidermotropic cytotoxic lymphoma) and type E (angioinvasive type) has been described recently. We describe a 27-year-old man presented with a history of asymptomatic erythematous papules on both upper and lower limbs noted since 10 years of age. There were no systemic symptoms. Biopsy revealed an atypical dermal lymphoid infiltrate with epidermotropism, and the immunohistochemical markers showed a diffuse positivity for CD3, CD8, CD56, T1A and granzyme B with the focal positivity of CD30. All other relevant tests were normal. In this case report of a recently described delineated variant of LyP we emphasize the indolent course of this entity although the histology would suggest a more aggressive disease.

Abstract
The aim of the present work was to study the epidemiology of Salmonella enterica serovar Enteritidis (S. Enteritidis) in Greece, comparing all the food and food animal isolates during a 3-year period with clinical isolates. Submission of the generated data to the PulseNet Europe database was carried out in order to study the population structure of this particular serovar and indicate possible connections with European strains. One hundred and sixty-eight (168) S. Enteritidis strains of human, animal, and food origin, isolated during the period 2008-2010 in Greece, were studied. Strains were characterized by phenotypic (antibiotic resistance) and molecular [pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST)] methods. PFGE revealed 39 XbaI, 48 BlnI, and 80 XbaI-BlnI distinct pulsotypes, suggesting several clones circulating through the food chain and multiple sources of transmission. Submission to the PulseNet Europe database indicated that PFGE profile SENTXB.0001, the most common PFGE profile in Europe, was also predominant in Greece (33.3 %). MLST showed that all the strains studied shared the same sequence type (ST11), representing the most common ST in Europe. High rates of resistance to nalidixic acid were observed among human and poultry isolates (~25 %), indicating the potential fluoroquinolone treatment failure. Our data suggest that strains originating from multiple reservoirs circulated in Greece through the food chain during the study period. Predominant profiles in Greece were common to PulseNet Europe profiles, indicating similarities between the S. Enteritidis populations in Greece and Europe.

Abstract
OBJECTIVE To evaluate 'Gold Line', a 24/7, nurse-led telephone and video-consultation support service for patients thought to be in the last year of life in Bradford, Airedale, Wharfedale and Craven. METHOD Data on the time and nature of all calls between 1 April 2014 and 30 March 2015 were obtained from the patient Electronic Records. Interviews with 13 participants captured patients and carers perspectives. RESULTS To date, 3291 patients have been referred to the Gold Line. During the study period, 42% of registered patients had a non-cancer diagnosis and 45.2% of service users were not known to Specialist Palliative Care services. The median time on the caseload was 49 days (range 1-504 days). 4533 telephone calls and 573 video consultations were made involving 1813 individuals. 39% of the 5106 contacts were resolved by the Gold Line team without referral to other services. 69% of calls were made outside normal working hours. Interviews with patients and carers reported experiences of support and reassurance from the Gold Line and the importance of practical advice was emphasised. Current data (year to October 2015) show that 98.5% of calls (4500/4568) resulted in patients remaining in their place of residence. CONCLUSIONS A nurse led, 24/7 telephone and video consultation service can provide valuable support for patients identified to be in the last year of life and for their carers. The line enabled them to feel supported and remain in their place of residence, hence reducing the pressure for avoidable hospital admissions and use of other services. Providing this service may encourage healthcare professionals to identify more patients approaching the last year of life, widening support offered to this group of patients beyond those known to specialist palliative care services.

Abstract
We present a case of extracavitary primary effusion lymphoma presenting, as jejunal polyps in a 38-year-old man. This is the first report of this entity from India. Although rare in our country, the diagnosis should be suspected in cases of CD20 negative large cell lymphoma with plasmablastic or immunoblastic differentiation in seropositive patients. Immunostaining for latency-associated nuclear antigen-1 and in situ hybridization for Epstein-Barr virus-associated RNA will confirm the diagnosis.

Abstract
SETTING Seventeen peripheral health institutions (PHI) in Kolar district (population: 0.5 million), South India. OBJECTIVE To assess the feasibility and results of screening patients with tuberculosis (TB) for diabetes mellitus (DM) at peripheral level. DESIGN From January to September 2012, all TB patients were assessed for DM. Those with unknown DM status were screened for the disease (free of charge) by trained laboratory technicians at each PHI, using a glucometer supplied by the national programme on a capillary blood sample. Those with fasting blood glucose (FBG) ≥ 126 mg/dl (≥7 mM) were diagnosed as DM-positive. RESULTS Of 362 TB patients, 358 (99%) were assessed for DM and 62 (17.1%) had the diseases-53 (14.6%) had a previous history of DM and 9 (2.9%) were newly diagnosed. All new DM patients were enrolled into DM care. Higher DM prevalence was found among TB patients aged ≥40 years, smokers and those with smear-positive pulmonary TB. To detect a new case of DM, the number needed to screen (NNS) among TB patients was 40. CONCLUSION Screening of TB patients for DM was feasible and effective in a peripheral setting. The availability of trained laboratory technicians and free services at every PHI made the intervention feasible. The study has contributed towards a national policy decision in this regard.
