Extraprostatic Spindle Cell Stromal Tumor of the Prostate: Case Report
2007
Several benign and malignant nonepithelial and stromal-like lesions arise in the prostate. Because such lesions are rare, their recognition is essential, because treatment and prognosis depend on an adequate pathohistologic classification. We report a case of an 83-year-old man with a stromal tumor of the prostate of uncertain malignant potential (STUMP). He presented with urinary retention and rectal constipation. On bimanual examination, a rectally and suprapubically palpable mass was found. Imaging studies revealed a 12 x 8 cm pararectal inhomogeneous mass of uncertain origin compressing rectum and urethra. The tumor was resected by a retropubic approach and examined immunohistochemicall…
Usefulness of ileostomy defunctioning stoma after anterior resection of rectum on prevention of anastomotic leakage A retrospective analysis
2016
Anastomotic leakage is one of the major complications occurring after anterior resection of rectum. A defunctioning stoma is usually created routinely or on surgeons' discretion. The aim of this study was to investigate the usefulness of temporary ileostomy to prevent anastomotic leakage comparing the postoperative course of patients with and without defunctioning loop ileostomy.Patients that underwent anterior resection of rectum were recruited. 140 patients were enrolled and divided in two groups: patients without and with defunctioning loop ileostomy. Patients' characteristics and other useful data were recorded. A comparison between the two groups was made. The minimum follow-up was 11 …
Procalcitonin and C-reactive protein as early predictors of anastomotic leak in colorectal surgery: a prospective observational study.
2013
Although the early diagnosis of anastomotic leak is a key point in reducing its clinical consequences, in daily practice, anastomotic leak diagnosis is often late.The aim of this study was to determine whether procalcitonin and C-reactive protein are good predictors of anastomotic leak in colorectal surgery.This is a prospective observational study.This study was conducted by a specialized colorectal multidisciplinary team of a tertiary teaching hospital.A series of 205 consecutive patients who underwent elective colorectal surgery in a specialized unit was prospectively analyzed. The following data were collected: demographic, surgical, ASA class, POSSUM, and morbidity. During the first 5 …
Expression of epithelial antigens EPM-1 and EXO-1 in normal, transitional, inflammatory and neoplastic colorectal mucosa
1993
EPM-1 (a high molecular weight glycoprotein) and EXO-1 (a carbohydrate epitope expressed on polar neutral glycolipids and mucins) are two developmental antigens of normal and neoplastic human epithelia and were characterised by monoclonal antibodies. Their distribution was investigated in normal and pathological human colorectal mucosa. In normal mucosa, EPM-1 and EXO-1 showed characteristic expression patterns. EPM-1 was differentially expressed along the crypt villus axis with maximum at the crypt basis. EXO-1 was present throughout the whole mucosa. The characteristic gradient of EPM-1 expression along the crypt axis in normal mucosa was no longer detectable in benign polyps. Intact grad…
EURECCA colorectal: multidisciplinary management: European consensus conference colon & rectum.
2014
Contains fulltext : 137861.pdf (Publisher’s version ) (Closed access) BACKGROUND: Care for patients with colon and rectal cancer has improved in the last 20years; however considerable variation still exists in cancer management and outcome between European countries. Large variation is also apparent between national guidelines and patterns of cancer care in Europe. Therefore, EURECCA, which is the acronym of European Registration of Cancer Care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012, the first multidisciplinary consensus conference about…
Short- and Long-Term Quality of Life and Bowel Function in Patients With MRI-Defined, High-Risk, Locally Advanced Rectal Cancer Treated With an Inten…
2015
Objective Intensified preoperative treatments have been increasingly investigated in locally advanced rectal cancer (LARC), but limited data are available for the impact of these regimens on quality of life (QoL) and bowel function (BF). We assessed these outcome measures in EXPERT-C, a randomized phase 2 trial of neoadjuvant capecitabine combined with oxaliplatin (CAPOX), followed by chemoradiation therapy (CRT), total mesorectal excision, and adjuvant CAPOX with or without cetuximab in magnetic resonance imaging-defined, high-risk LARC. Methods and Materials QoL was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR29 questionnaires. Bowel inc…
Storage Diseases: Diagnostic Position
2013
Storage diseases are metabolic multiorgan conditions, which may be divided into lysosomal and nonlysosomal diseases. Disorders of the lysosomal type require electron microscopy for morphological diagnosis. It is the metabolic substrate that determines involvement of the cell type or organ in the individual storage disease, allowing extracerebral biopsies, for instance, in the neuronal ceroid-lipofuscinoses (NCL). A hierarchy of tissues biopsied for diagnosis can be based on easy accessibility: blood lymphocytes, skin, conjunctiva, rectum, skeletal muscle. Lysosomal diseases are divided into vacuolar and nonvacuolar ones. NCL display variegated ultrastructural patterns. Drugs may induce lyso…
Solitary Rectal Ulcer
1979
Solitary ulcers of the rectum may be traumatic in origin and caused by thermometers, occasionally by digital removal of a fecal impaction, or by deviate sexual behavior. Solitary rectal ulcers may also be a manifestation of Crohn’s disease. Very rarely, ectopic gastric mucosa is their cause. For the vast majority of solitary rectal ulcers, the explanation remains unknown. Occasionally, the ulcers are accompanied by localized inflammation of the mucosa within the distal segment of the rectum with edema, erythema, and circumscribed whitish flecks in a thickened bowel wall covered by excessive secretions. The changes are found predominantly in the ventral portion of the rectum, and in contrast…
Hereditary familial polyposis and Gardner’s syndrome: Contribution of the odontostomatology examination in its diagnosis and a case description
2005
La poliposis adenomatosa familiar (PAF) y su variante fenotípica, el síndrome de Gardner, constituyen una infrecuente patología hereditaria autosómica dominante. Se caracterizan por el desarrollo, generalmente durante la segunda y tercera década de la vida, de múltiples pólipos adenomatosos en el colon y en el recto. Estos pólipos tienen un riesgo elevado de transformación maligna subsiguiente, cosa que suele ocurrir en las décadas tercera y cuarta de la vida. Las manifestaciones fenotípicas de la PAF pueden ser muy variadas. Así, además de los pólipos colorrectales, los individuos afectos pueden presentar manifestaciones extracolónicas, entre las que se destacan: pólipos gastroduodenales, …
Breakthrough Pain (BTP) in Opioid-Tolerant Cancer Patients: A Pan-European Open-Label Multicentre Study with Fentanyl Buccal Tablet (FBT)
2012
ABSTRACT BTP, a transitory exacerbation of pain that occurs on a background of otherwise controlled persistent pain, is a common problem in cancer patients. FBT is indicated for the treatment of BTP in adults with cancer already receiving maintenance opioid therapy for chronic cancer pain and should be titrated to an effective dose that provides adequate analgesia and minimises undesirable events. In this study, patients entered a screening period and were randomized during an open-label titration period to a starting FBT dose of 100 µg (group A) or 200 µg (group B) to identify the FBT effective dose and then treated in an open-label period (for 8 BTP episodes). Patients' inclusion followed…
