Hypoxia enhances immortality and metastatic properties of solid tumors. Deregulation of histone acetylation has been associated with several metastatic cancers but its effect on hypoxic responses of cancer cells is not known. This study aimed at understanding the effectiveness of the hydrazinocurcumin, CTK7A, an inhibitor of p300 lysine/histone acetyltransferase (KAT/HAT) activity, in inducing apoptosis of gastric cancer cells (GCCs) exposed to cobalt chloride (CoCl

Patients in the perioperative period and intensive care unit are commonly exposed to blood transfusion (BT). They are at increased risk of transfusion transmitted bacterial, viral and protozoal diseases. The risk of viral transmission has decreased steadily, but the risk of bacterial transmission remains same. Bacterial contamination is more in platelet concentrates than in red cells and least in plasma. The chances of sepsis, morbidity and mortality depend on the number of transfusions and underlying condition of the patient. Challenges to safe BT continue due to new emerging pathogens and various management problems. Strategies to restrict BT, optimal surgical and anaesthetic techniques to reduce blood loss and efforts to develop transfusion alternatives should be made. Literature search was performed using search words/phrases blood transfusion, transfusion, transfusion transmitted diseases, transfusion transmitted bacterial diseases, transfusion transmitted viral diseases, transfusion transmitted protozoal diseases or combinations, on PubMed and Google Scholar from 1990 to 2014. © 2014, Indian Society of Anaesthetists.

Aim: During the present investigation, two types of keratinized round cells (KRCs), large keratinized round cells (LKRCs) and small keratinized round cells (SKRCs), were observed in the exfoliated buccal smears of oral cancer patients. Therefore, the aim of the present study was to determine the practical utility of KRCs during difficult diagnosis and in the early detection of oral squamous cell carcinoma (OSCC) through cytomorphometric analysis. Materials and Methods: In a hospital-based case control study, exfoliated scrape smears were collected from 136 patients clinically diagnosed as suffering from pre-cancerous lesions and OSCC and a parallel set of 136 samples were also collected from non-addicted and non-cancerous healthy individuals from different regions of Odisha, and this was considered as the control group. Wet-fixed smears were stained by adopting Papanicolaou's staining protocol and counter-stained with Giemsa's solution. One thousand cells were screened and keratinized round cells along with other cytological atypia were scored. Cytomorphometry was carried out using a computer-assisted Cat Cam 1.30 (1.3 Mega Pixel) microscope camera. The findings were statistically analyzed and interpreted with respect to oral sites, age groups and sexes. Results: Cytomorphometrically, the nucleus to cytoplasmic ratio of the LKRCs was 1:4.7 in males and 1:4.3 in females, and in SKRCs it was calculated to be 1:4.6 in males and 1:5.2 in females. Conclusion: Cellular keratinization, hyperchromasia and increased N/C ratios in both LKRCs and SKRCs indicates the state of malignancy and thus the present finding has a practical value in early detection and diagnosis of OSCC patients.

Background: Cytopathology of human oral squamous cell carcinoma reveals cytological pleomorphism. In this investigation, cytometry was used in an attempt to analyse the importance of the rare occurrence of keratinized strap cells in the buccal mucosa of human oral neoplasms. Patients and methods: A case–control study was undertaken in which exfoliated cytosmears were collected, by scraping, from 136 clinically diagnosed oral cancer patients. Wet fixed cytosmears were stained by use of Papanicolaou’s staining procedure and counter-stained with Giemsa’s solution. One thousand cells were screened, and keratinized strap (Anitschkow) cells (KSC-A) and other cytological atypias were counted. Cytomorphometry was performed by use of a computer-assisted microscope camera. The findings were analysed statistically and interpreted in respect of age group, oral site, and sex. Results: Transformation of an angulated and polygonal normal oral squamous cell into a keratinized narrow strip or ribbon-like flat projection results in what is called a keratinized strap cell (KSC). Nuclear pleomorphism in keratinized strap cells was observed to be narrow spindle, rod, and bar-shaped and to resemble Anitschkow cells. From the nature of the staining, the structural peculiarity, and the resemblance to Anitschkow cells, KSC, a rarely observed oral cytological atypia, were renamed as keratinized strap (Anitschkow) (KSC-A) cells. Cytometrically, the nuclear-to-cytoplasmic (N/C) ratio for KSC-A was calculated to be 1:11.2 for males and 1:11.3 for females; these are more than those for the normal counterparts. Conclusion: Rare occurrence, cellular keratinization, nuclear pleomorphism, hyperchromasia, and increased N/C ratios for KSC-A in oral carcinoma, for both sexes, indicate a state of malignancy; this finding is, thus, of practical value for early detection and diagnosis of oral squamous cell carcinoma patients. © 2015, Japan Society of Clinical Oncology.

Carcinoma of male breast constitutes 1% of total breast malignancy. Carcinoma arising from ectopic breast tissue in male is an extremely rare entity and can be misdiagnosed. Ectopic breast tissue may be supernumerary or aberrant one. Despite morphologic difference, ectopic breast tissue presents characteristics analogous to orthoptic breast in terms of functional and pathologic degeneration. Most of the ectopic breast tissue occurs in thoracic or abdominal portion of milk line. If found in a location outside the milk line, it proves a diagnostic dilemma. We are reporting a case of 60-year-old male who presented with a fixed mass of size 10cm8cm, in right chest wall infraclavicular area of 6 months duration. Histopathology of the mass revealed invasive duct carcinoma. He had no evidence of malignant or occult primary lesion in the bilateral mammary glands. Due to the paucity of the literature, incidence of ectopic male breast cancer and its management is not well understood. There is high probability of misdiagnosis of this disease. To the best of our knowledge this is the first described case of ectopic male breast cancer in the chest wall, not along the milk line, which is being reported here for documentation.

Hypoxia promotes cancer progression, and metastasis. The major protein expressed in hypoxic solid cancer is hypoxia-inducible factor 1 (HIF1). We show that enhanced phosphorylation of a conventional protein kinase C isoform, PKC, at threonine 638 (T(638)) by hypoxia-mimetic cobalt chloride induces HIF1 in nuclei of gastric epithelial cells (GECs). Moreover, phospho-T(638)-PKC (P-PKC) interacts with p300-HIF1 complex in the nuclei of hypoxic GECs and PKC phosphorylation at T(638) enhances transcriptional activity of HIF1. High P-PKC expression in neoplastic gastric cancer biopsy samples as compared to nonneoplastic samples suggests that P-PKC might act as an indicator of gastric cancer progression.

Primary squamous cell carcinoma of the renal parenchyma is an extremely rare entity. The diagnosis of squamous cell carcinoma of the renal pelvis is usually unsuspected due to the rarity and inconclusive clinical and radiological features. Most of the patients are diagnosed at an advanced stage and are with poor outcome. Radical nephrectomy is the mainstay of the treatment. We reported a case of squamous cell carcinoma of the kidney in a 50-year-old female who presented with the right sided abdomen pain. The patient was treated with radical nephrectomy.

Cancer is a leading cause of mortality worldwide. Early diagnosis and treatment of cancer may curb the growing burden of the disease. Understanding cancer patients' navigation pathways for seeking treatment is important in order to facilitate early diagnosis and treatment. With this background we conducted a hospital-based cross-sectional study comprising 68 randomly selected cancer inpatients in a tertiary cancer specialty hospital in Odisha, India, to explore the treatment-seeking pathways of the cancer patients and the barriers and enablers in seeking treatment. Financial constraint is one of the major reasons for the delay in accessing treatment, even when patients are suspected of or diagnosed with cancer. Low awareness of the presenting signs and symptoms of cancer and limited knowledge of the availability of cancer diagnosis and treatment facilities are major factors contributing to delay. Family and friends' support is found to be the major enabling factor toward seeking treatment. Generation of awareness of cancer among the general population and primary-care practitioners - including those in alternative systems of medicine - is important. Information on diagnostic and treatment services appears to be a felt need. © 2013 Elsevier Ltd.

The EuroQol five-dimensions - 3-level (EQ5D) is a versatile quality of life (QOL) instrument with five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and a visual analog scale. It can be used to calculate quality-adjusted life years. We aimed to evaluate the validity, reliability, and responsiveness of an Odia version of EQ5D and to study the QOL of cancer patients in our part of the country as cancer treatment in India still focuses largely on longevity due to scarcity of resources.The EQ5D tool was translated into Odia language in collaboration with the EQ group. This tool and the World Health Organization-5 (WHO-5) questionnaires were administered to 155 surgical outpatients and 150 cancer patients in two hospitals of Eastern India. The convergent and discriminant validities (construct validity), concurrent validity, reliability (test-retest method of administering the tool to a part of the population after 7-14 days), and the internal consistency (Cronbachs alpha) were measured using preestablished hypotheses. The data from the cancer patients were analyzed separately.The QOL worsened with age and was worse in cancer patients proved that the tool had good construct validity. The Anxiety Depression dimension had good correlation with all the dimensions WHO-5 (rho > 0.4) indicating a good concurrent validity. Internal consistency and reliability of the tool were good (Cronbachs alpha > 0.7). Cancer patients had a poor QOL (mean EQ5D index 0.37SD 0.4) with male patients, patients with Grade II cancer or referred for pain care services and those with living spouses reporting worse QOL.The Odia version of the EQ5D has good reliability and validity for the measurement of health status in cancer and outpatient department patients. Cancer patients in this part of the country have a poor QOL and may need a closer look at pain management and improved societal support systems.
