Cerebral cavernous malformations (CCMs) are present in up to 0.5% of the general population. While CCMs have been considered congenital lesions, numerous reports have observed de novo formations in patients with the familial form of CCM and in patients after cranial radiotherapy. Outside of these circumstances, there is scant evidence as to the potential etiologies of CCM. We present a 48-year-old woman with a medical history of endometrial hyperplasia concomitant endometrial polyps demonstrating a large de novo CCM, which grew to a large size in a period of 20 months...

INTRODUCTION: The development of mania during weaning is an underreported phenomenon that has received little attention in the recent past. Lack of timely diagnosis and effective management can negatively affect not only the mother but also her family. Main issue: I describe the case of a woman who experienced onset of mixed mania during weaning. At that time, she was diagnosed with bipolar I disorder, current episode manic, and a mixed-features specifier. The woman had a history of bipolar II disorder and a family history of postpartum depression and bipolar disorder...

Background & Aims: Pancreatic ductal adenocarcinoma (PDAC) remains the most aggressive malignancy with the lowest 5-year survival rate of all cancers in part owing to the lack of tumor-specific therapy and the rapid metastatic nature of this cancer. The gastrointestinal peptide gastrin is a trophic peptide that stimulates growth of PDAC in an autocrine fashion by interaction with the cholecystokinin receptor that is overexpressed in this malignancy. Methods: We developed a therapeutic novel polyplex nanoparticle (NP) that selectively targets the cholecystokinin receptor on PDAC...

Background: Sarcomatoid differentiation in renal cell carcinoma (sRCC) is histologically characterized by anaplastic changes of renal cell carcinoma (RCC) subtypes, which has been associated with a poor prognosis. sRCC is managed more aggressively than RCC without sarcomatoid components, so pre-operative detection of sarcomatoid differentiation would significantly affect surgical management. The purpose of this study is to compare the quantification of sarcomatoid features in RCCs on pre-operative magnetic resonance imaging (MRI) to standard histological examination...

The conservative management of large, odontogenic, developmental cysts involving the jaws in young children using the technique of decompression has become increasingly popular to reduce the incidence of morbidity associated with aggressive treatment modalities. The lack of development of a stock device has made clinicians to explore various possible and readily available materials to customize the devices. This paper highlights the use of a novel material to be used as a decompression device that is readily available and can be used with good patient compliance and a predictable outcome...

With dismal survival rate pancreatic cancer remains one of the most aggressive and devastating malignancy. Predominantly, due to the absence of a dependable methodology for early identification and limited therapeutic options for advanced disease. However, it takes over 17 years to develop pancreatic cancer from initiation of mutation to metastatic cancer; therefore, if diagnosed early; it may increase overall survival dramatically, thus, providing a window of opportunity for early detection. Recently, genomic expression analysis defined 4 subtypes of pancreatic cancer based on mutated genes...

Long non-coding RNAs (lncRNAs) have been shown to exert essential roles in development and progression of tumors. Here we discovered a novel lncRNA, RAB11B antisense RNA (RAB11B-AS1), which is markedly down-regulated in human osteosarcoma (OS) and associated with OS metastasis and poor prognosis. We find that reduction of RAB11B-AS1 significantly facilitates proliferation, migration and invasiveness and prevents apoptosis of OS cells and results in lower sensitivity to cisplatin in these cells. In contrast, up-regulation of RAB11B-AS1 suppresses the aggressive behaviors of OS cells...

Breast cancer is a complex disease exhibiting extensive inter- and intra-tumor heterogeneity. Inflammation is a well-known driver of cancer progression, often attributed to immune cells infiltrating the tumor stroma. However, tumor cells themselves are capable to secrete a variety of inflammatory molecules, of which we understand very little about their role in intra-clonal communication. We recently reported the capacity of triple negative cell lines to induce a cancer stem cell (CSC)-like phenotype and invasion properties into luminal cells, a mechanism mediated by pro-inflammatory cytokines that up-regulated the CXCL12/CXCR4/CXCR7 chemokine signaling axis...

Recent studies revealed that some passenger strands of miRNAs acted as anti-tumor or oncogenic miRNAs in cancer cells. In this study, we focused on miR-455-5p (the passenger strand) and miR-455-3p (the guide strand) based on microRNA (miRNA) expression signatures of cancer cells. Both miR-455-5p and miR-455-3p were downregulated in renal cell carcinoma (RCC) tissues and low expression of these miRNAs was significantly associated with poor prognosis. Cancer cell proliferation, migration and invasive abilities were significantly inhibited by ectopic expression of miR-455-5p and miR-455-3p ...

Small cell lung cancer (SCLC) is a very aggressive form of lung cancer. SCLC treatment requires multidisciplinary management and timely treatment. Radiation therapy is an important part of management of all stages of SCLC, in the curative as well as in the palliative setting. The role of radiation therapy in all stages of SCLC has changed in recent years; this article describes these changes and highlights the role of radiation therapy in the management of SCLC.

Non-small-cell lung cancer (NSCLC) accounts for ~80% of human lung cancer cases and is the most common cause of cancer-associated mortality worldwide. Reports have indicated that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and Iodine-131 (I-131) can induce tumor cell apoptosis. The purpose of the present study was to investigate the additive efficacy of TRAIL and I-131 on NSCLC cells. The present study demonstrated that additive treatment of TRAIL and I-131 (TRAIL-I-131) significantly inhibited the growth and aggressiveness of NSCLC cells compared with single TRAIL or I-131 treatment...

Colorectal carcinoma (CRC) is the second leading cause of cancer mortality worldwide. O-glycosylated mucins at the cell surface of colonic mucosa exhibit alterations in cancer and are involved in fundamental biological processes, including invasion and metastasis. Certain members of the GalNAc-transferase family may be responsible for these changes and are being investigated as novel biomarkers of cancer. In the present study the prognostic significance of GalNAc-T6 was investigated in patients with CRC patients...

Tumor protein 53 ( TP53 ) is a tumor suppressor gene that encodes tumor protein p53. Tumor protein p53 regulates the expression of target genes in response to cellular stress. Additionally, p53 participates in the regulation of cell cycle checkpoints, DNA repair and apoptosis. Mutations in the TP53 gene are associated with numerous types of human cancer, including breast cancer, sarcomas, brain tumors and adrenal cortical carcinomas. In breast cancer, TP53 mutations are a negative prognostic factor. Tumors with TP53 mutations are more likely to be aggressive (triple-negative or human epidermal growth factor receptor 2-positive breast cancer), and resistant to chemotherapy and radiotherapy...

p62 (also known as sequestosome 1) protein, is a small regulatory protein that accumulates in autophagy-defective cells that has been demonstrated to be involved in the prognosis and survival of patients with several types of cancer. However, to the best of our knowledge, there have been no such studies for osteosarcoma (OS). In the present study, the expression of p62 in 70 OS samples was determined using immunohistochemistry and its association with various clinicopathological factors was assessed. The results demonstrated that the overexpression of p62 protein was detected in 77...

Retroperitoneal liposarcoma is a rare type of cancer. Relapse after surgery is frequent, and relapsing tumors tend to be more aggressive and less differentiated each episode, worsening the prognosis. This report describes the case of a 42-year-old female diagnosed with retroperitoneal liposarcoma after complete tumor resection. At the 3-month follow-up, another expansive lipomatous mass in the retroperitoneal area almost the same size as the previous one was detected. The patient underwent a new surgery, followed by first-line treatment with a gemcitabine- and docetaxel-based regimen for 8 cycles...

Acute pancreatitis (AP) is an inflammatory disease presenting from mild localized inflammation to severe infected necrotic pancreatic tissue. In the literature, there are a few cases of hypothermia-induced AP. However, the association between hypothermia and AP is still a myth. Generally, mortality from acute pancreatitis is nearly 3-6%. Here, we present a 40-year-old chronic alcoholic female who presented with acute pancreatitis induced by transient hypothermia. A 40-year-old chronic alcoholic female was hypothermic at 81°F on arrival which was improved to 91...

Introduction: Mixed epithelial and stromal tumour of the kidney (MEST) is a rare and distinctive neoplasm accounting for 0.2% of all renal cancers. Most of these tumours behave in a benign fashion but 13 cases with malignant transformation have already been reported. We present the first case of an extremely aggressive MEST with rapid recurrence after radical treatment, demonstrating objective response to chemotherapy. Case presentation: A 31-year-old female presented to the hospital complaining of gross hematuria...

Background: Primary tumours of the gastrointestinal tract are very uncommon in children. They can present with anaemia caused by gastrointestinal acute or chronic bleeding. One of the most common gastrointestinal tumours is Burkitt lymphoma. This lymphoma is a highly aggressive, rapidly growing B-cell neoplasm, making survival without treatment possible only for a few weeks. For this reason it requires immediate hospitalization and treatment. Case report: We report a case of a gastric Burkitt lymphoma in an adolescent girl who presented with anaemia due to gastrointestinal bleeding...
