Growth of N-substituted polypyrrole layers in ionic liquids: Synthesis and its electrochromic properties

A new series of pyrrole family, N-substituted phenyl attached alkyl at the ortho, meta and para position were synthesized by a straight forward method and were exploited as an innovative monomer for electroactive polymers. Ionic liquids were employed as a medium for electro-polymerization of these monomers to obtain N-(methyl)phenyl polypyrroles. N-substituted polypyrroles show different morphologies and conductivity according to position of methyl group on the benzene ring and synthesis medium. The electrical conductivity value varies with the position of methyl group and was > 10(-5) S/cm, higher than the sample obtained from conventional media. The resulting polymer films were characterized by Fr-IR and UV-Vis spectroscopy, contact angle measurements, cyclic voltammetry and scanning probe microscopic technique along with their electrochromic behavior

Colonic Metastasis from Carcinoma of the Breast that Mimicks a Primary Intestinal Cancer

Although the lung, liver, or bones are the most common location for distant metastases in breast cancer patients, metastases to the intestinal tract are very rarely recognized in the clinic. We will present an unusual case of colonic metastasis from a carcinoma of the breast that mimics a primary intestinal cancer, along with a through review of English language medical literature. Despite the fact that isolated gastrointestinal (GI) metastases are very rare and much less common than benign disease processes or second primaries of the intestinal tract in patients with a history of breast cancer, metastatic disease should be given consideration whenever a patient experiences GI symptoms

Evaluation of prognostic factors and comparison of systemic treatment modalities in patients with recurrent or metastatic endometrial carcinoma

Background: Prognostic factors related to survival in patients with inoperable metastatic or recurrent endometrial carcinoma (MREC) have remained unclear due to lack of clinical trials.The management of these patients is also controversial.This study was performed to compare the efficacy and toxicity profiles of two different systemic therapies (chemotherapy vs hormonal therapy) given for the treatment of patients with MREC and to identify the impact of various prognostic factors on the survival

Prevalence of major depression in patients with cancer and related factors

Objective: Worldwide, cancer is the second most frequent cause of death after the ischemic heart disease. Lifetime prevalence of psychiatric co-morbidities in cancer patients is 30-40%. Major depression is the most prevalent psychiatric disorder in patients with cancer. Major depression has a negative effect on quality of life, self-care, treatment compliance, prognosis, and treatment response of the cancer patient. In this study, we evaluated the prevalence of major depression in patients with cancer and the related factors which might affect this co-morbidity. Methods: Hundred patients with cancer (53 men and 47 women) who attended to oncology outpatient units were recruited to the study. Participants were assessed with 'Structured Clinical Interview for DSM-IV (SCID) - Mood Disorders Module' and 'The Questionnaire for the Assessment of Patients with Cancer'. Results: The prevalence of major depression in patients with cancer was 22%. The prevalence of major depression was higher in women than in men. Insomnia was found in 50% of patients. Insomnia was recognizedin 20% of patients with breast cancer and 15% of patients with lung cancer. Suicidal ideation was found in 11% of the patients with cancer. The prevalence of suicidal ideation increased with age and it decreased as the disease progressed. Conclusion: Major depression is a frequent psychiatric problem in the patients diagnosed with cancer. By reason of frequency, early recognition of major depression and the related factors will provide appropriate treatment. The frequency of suicidal ideation is even important in this population. Psychosocial support and psychiatric treatment approaches should be the focus of further attention in oncology clinics
