THE SAXOPHONIST'S HERNIA: A RARE CASEREPORT OF ANTERIOR PRIMARY PERINEAL HERNIA IN A YOUNG MALE PATIENT.
2017
Perineal hernia is the protrusion of an intra-abdominal structure into the perineal area, that could be primitive or secondary to trauma or abdominoperineal resection. Main treatment could be transabdominal, transperineal or combined. Here is a rare case of anterior perineal hernia in a young saxophone male patient, treated with a mininvasive perineal approach. A 25-year-old Caucasian male patient referred 1-year history of perineal pain. The pain was more severe when he played his saxophone. Local exam was negative but a dynamic perineal ultrasonography revealed a small anterior perineal hernia. The defect was repaired with a polypropylene plug and the patient was discharged the day after.…
Diagnosis and Classification of 17 Diseases from 1404 Subjects via Pattern Analysis of Exhaled Molecules.
2016
We report on an artificially intelligent nanoarray based on molecularly modified gold nanoparticles and a random network of single-walled carbon nanotubes for noninvasive diagnosis and classification of a number of diseases from exhaled breath. The performance of this artificially intelligent nanoarray was clinically assessed on breath samples collected from 1404 subjects having one of 17 different disease conditions included in the study or having no evidence of any disease (healthy controls). Blind experiments showed that 86% accuracy could be achieved with the artificially intelligent nanoarray, allowing both detection and discrimination between the different disease conditions examined.…
High-flow nasal cannula versus non-invasive ventilation for acute hypercapnic respiratory failure in adults: a systematic review and meta-analysis of…
2022
Abstract Background Non-invasive ventilation (NIV) with bi-level positive pressure ventilation is a first-line intervention for selected patients with acute hypercapnic respiratory failure. Compared to conventional oxygen therapy, NIV may reduce endotracheal intubation, death, and intensive care unit length of stay (LOS), but its use is often limited by patient tolerance and treatment failure. High-flow nasal cannula (HFNC) is a potential alternative treatment in this patient population and may be better tolerated. Research question For patients presenting with acute hypercapnic respiratory failure, is HFNC an effective alternative to NIV in reducing the need for intubation? Methods We sear…
Transforming Growth Factor Beta 1 Serum Levels in Patients with Preinvasive and Invasive Lesions of the Breast
2004
Transforming growth factor beta (TGF-beta)1 is thought to be involved in breast carcinogenesis. TGF-beta1 acts in an antiproliferative manner in the early stages of breast carcinogenesis, but promotes tumor progression and metastases in the advanced stages of the disease. No data have been published on serum TGF-beta1 in breast cancer. We investigated TGF-beta1 serum levels in patients with breast cancer (n=135), ductal carcinoma in situ (DCIS) I to III (n=67) or fibroadenoma (n=35), and in healthy women (n=40) to determine its value as a differentiation marker between malignant, pre-invasive and benign diseases and as a predictive marker for metastatic spread. Median (range) TGF-beta1 seru…
Phase 2 Trial of Docetaxel, Gemcitabine, and Oxaliplatin Combination Chemotherapy in Platinum- and Paclitaxel-Pretreated Epithelial Ovarian Cancer
2009
Background: This phase 2 trial was designed to evaluate the efficacy and toxicity of a combination of docetaxel, gemcitabine, and oxaliplatin for platinum- and paclitaxel-pretreated epithelial ovarian cancer. Patients and Methods: Heavily pretreated patients (N = 30; median age, 61 years) received docetaxel, 55 mg/m2; gemcitabine, 500 mg/m2 (day 1); and oxaliplatin, 70 mg/m2 (day 2) biweekly. Twelve patients had platinum-sensitive disease, and 18 patients had platinum-resistant disease. Results: Median follow-up was 18.6 months. No differences in patient characteristics were observed between patients with carboplatinum-sensitive and carboplatinum-resistant disease. In patients with carbopla…
Monocyte Chemoattractant Protein-1 Serum Levels in Patients with Breast Cancer
2003
The chemokine monocyte chemoattractant protein (MCP)-1 is thought to be involved in breast carcinogenesis. We evaluated MCP-1 serum levels in patients with breast cancer (n = 135), ductal carcinoma in situ (DCIS) I-III (n = 30), benign breast lesions (n = 143) and in healthy women (n = 27). We determined the value of MCP-1 serum levels as a differentiation marker between malignant, preinvasive and benign breast diseases and as a predictive marker for the biological phenotype of breast carcinoma. Median (range) MCP-1 serum levels in patients with breast cancer, DCIS I-III, benign breast lesions and healthy women were 200 (57-692) pg/ml, 194 (58-525) pg/ml, 174 (39-529) pg/ml and 175 (67-425)…
Multivariate independent prognostic factors in endometrial carcinoma: A clinicopathologic study in 181 patients: 10 years experience at the Departmen…
2003
The aim of this study was to evaluate the biologic outcome of endometrial carcinomas as compared to clinical and pathologic parameters and to identify multivariate independent prognostic factors. Charts were abstracted from patients with endometrial carcinoma from 1985 to 1995. Data on clinicopathologic variables, adjuvant treatment, site of recurrence, and survival were collected. chi2 test was used to test association between variables. Kaplan-Maier method was used for survival analysis and Cox proportional hazards model for multiple regression analysis. Univariate analysis revealed that FIGO stage, tumor grade, depth of myometrial invasion, biochemical analysis of progesterone receptor s…
Imunohistochemical Demonstration of Carcinoembryonic Antigen (CEA) in 120 Mammary Carcinomas and its Correlation with Tumor Type, Grading, Staging Pl…
1985
Antisera to CEA were used for the immunohistochemical localization and quantification of this antigen in 120 Bouin-fixed, paraffin embedded mammary carcinomas. These results were compared to tumor type, grading, staging, biochemical receptor status, cytosolic CEA-levels of the same tumors, and preoperative plasma CEA-levels. Mammary carcinomas were usually characterized by a low percentage of CEA-positive tumor cells: 50.9% of the cases contained more than 5% CEA-positive tumor cells and were therefore defined as being CEA-histopositive in this study. A relation could be shown between CEA-histopositivity and the histologic tumor type. The majority of invasive lobular carcinomas, tubular, an…
Adhesive and invasive features in gliomas
2000
Summary This study aims at the in situ identification of factors mediating glioma cell invasion requiring adhesion, extracellular matrix degradation, and migration. Fortyfive gliomas (astrocytomas, glioblastomas, oligodendrogliomas, and mixed gliomas) were investigated for the immunohistochemical expression of the membrane protein CD44s, the basal lamina proteins laminin, collagen IV, and fibronectin, the lectin galectin-3 recognizing tenascin and N-CAM, as well as for the matrix-degrading enzymes metalloproteinases MMP-2, MMP-9, and cathepsin D. Besides vessels expressing basal lamina proteins, tenascin, MMP-2, MMP-9, and galectin-3, tumor cells revealed strong immunoreactivity for CD44s, …
Prospective seroepidemiologic study of human papillomavirus infection as a risk factor for invasive cervical cancer
1997
Background: Major risk factors for invasive cervical cancer include infection with human papillomavirus (HPV), infection with other sexually transmitted pathogens (e.g., Chlamydia trachomatis), and smoking. Since exposures to these risk factors can be related, the contribution of any single factor to cervical carcinogenesis has been difficult to assess. We conducted a prospective study to define the role of HPV infection in cervical carcinogenesis, with invasive cancer as an end point. Methods: A nested case‐control study within a joint cohort of 700 000 Nordic subjects was performed. The 182 women who developed invasive cervical cancer during a mean follow-up of 5 years were matched with 5…
