Spontaneous laceration of spleen with hilar lymph node metastasis: a case of primary splenic mantle cell lymphoma in elderly
Mantle cell lymphoma (MCL) is a type of non-Hodgkin (B-cell) lymphoma (NHL) with manifestations ranging from indolent to aggressive disease. It arises from mantle zone or primary follicle lymphocytes and is associated with translocation t (11;14) which is seen in almost all cases. Most of the cases present at stage III/IV with hepatospenomegaly, generalized lymphadenopathy, bone marrow involvement or lymphoid polyposis. Rate of relapse is high occurring in 50-60% patients and 5-year survival rates are low ~27-30%. Median overall survival is 3.5 years. Age >60 years, raised serum LDH, high mitotic count, Ki67>30%, blastoid or pleomorphic variants, TP53 mutation, gains in 3q,11q and deletions of 13q as well as 17p are important prognostic factors associated with worst outcome. Treatment involves conventional chemo-immunotherapy and stem cell transplantation (SCT). In our case the elderly patient had an atraumatic splenic rupture with no past medical history of trauma. The patient presented to the emergency department with severe abdominal pain in left upper quadrant. Thus emergency splenectomy was executed successfully, and the patient was stabilized. After receiving initial cycle of R-CHOP regime, he was lost to follow up. In this case report, we will discuss the clinical presentation, as well as current treatment guidelines for atraumatic splenic rupture

Steps towards collective sustainability in biomedical research
The optimism surrounding multistakeholder research initiatives does not match the clear view of policies that are needed to exploit the potential of these collaborations. Here we propose some action items that stem from the integration between research advancements with the perspectives of patient-advocacy organizations, academia, and industry
Study on role of fibular graft in non-union and complex fractures of long bone
Background: Road traffic injuries are the seventh most common cause of long bone fractures. Following high velocity limb trauma, the defects in the long bone are usually associated with appreciable soft-tissue losses. These open long bone injuries always require multidisciplinary managements to reconstruct the composite defects of bone and soft tissue.
Aims and Objectives: The aim of the study was to find out radiological and clinical outcome, complications, and union time in complex and non-union fractures of long bone managed by fibular graft.
Materials and Methods: Out of 50 cases, 40 cases were of complex fractures and ten cases were of non-union. We used Fibular strut grafts in reconstruction of bone defects and soft tissue injury.
Results: Thirty (60.0%) had excellent functional outcome, 10 (20.0%) had good, 6 (12.0%) had satisfactory, and 4 (8.0%) patients had poor outcome. Main complications were non-union 2 cases and 3 cases of superficial wound infection, which subsided by wound dressing and intravenous antibiotic treatment.
Conclusion: Free fibular grafting has been proven to be an ideal choice in the management of large segmental bone defects as well as in situations of biological failure of bone healing
Sudden hearing loss in a patient of Hodgkin’s lymphoma following vinblastine chemotherapy: a rare case report and review of the literature
Ototoxicity is a well-known complication of certain chemotherapeutic agents. There have been few reports of ototoxicity following administration of vincristine. However, vinblastine has seldom been implicated causing ototoxicity. We report a case of sudden bilateral hearing loss in a 32-year-old male patient of classical Hodgkin’s lymphoma following standard adriamycin, bleomycin, vinblastine, dacarbazine chemotherapy
Alterations in Cell-Extracellular Matrix Interactions during Progression of Cancers
Cancer progression is a multistep process during which normal cells exhibit molecular changes that culminate into the highly malignant and metastatic phenotype, observed in cancerous tissues. The initiation of cell transformation is generally associated with genetic alterations in normal cells that lead to the loss of intercellular- and/or extracellular-matrix- (ECM-) mediated cell adhesion. Transformed cells undergo rapid multiplication and generate more modifications in adhesion and motility-related molecules which allow them to escape from the original site and acquire invasive characteristics. Integrins, which are multifunctional adhesion receptors, and are present, on normal as well as transformed cells, assist the cells undergoing tumor progression in creating the appropriate environment for their survival, growth, and invasion. In this paper, we have briefly discussed the role of ECM proteins and integrins during cancer progression and described some unique conditions where adhesion-related changes could induce genetic mutations in anchorage-independent tumor model systems
A case report of all-trans retinoic acid-induced pseudotumor cerebri in an adult patient of acute promyelocytic leukemia
All-trans retinoic acid (ATRA), a derivative of vitamin A, is the first line drug for acute promyelocytic leukemia (APL). At the same time, ATRA is also associated with various side effects, including some life threatening conditions. We describe a case of ATRA-induced pseudotumor cerebri in an adult patient of APL
