Extradural Endoscopic Dissection of the Anterior Skull Base
1998
A study was conducted from February 29, 1996, to March 28, 1996, at the University of Brno's Pathology Institute in the Czech Republic to explore the possible application of craniofacial intracranial endoscopic techniques through minimal skin incisions and trephines in fresh cadavers (3 to 12 hours old). Through the trephines the dura was totally dissected from the bone. After this dissection a standard bicoronal incision and a full craniotomy was performed to assess the integrity of the meninges. This minimally invasive dissection of the skull base with the aid of an endoscope is characterized by fewer skin incisions, thereby avoiding the exposure of subcutaneous tissue, muscle, cranial bo…
Echocardiography in diagnosis of aortic dissection.
1989
In a multicentre study the accuracy of echocardiography was measured in 164 consecutive patients with suspected aortic dissection. The diagnosis was subsequently proven (82 patients) on the basis of transthoracic and transoesophageal echocardiography and additional diagnostic procedures, including computed tomography (CT), aortic angiography, and surgery and/or necropsy. The sensitivity and specificity of echocardiography were 99% and 98%, respectively, with positive and negative predictive values of 98% and 99%. For CT sensitivity was 83%, specificity 100%, and positive and negative predictive values 100% and 86%, respectively. For aortography sensitivity and specificity were 88% and 94%, …
The value of intraoperative frozen section examination of sentinel lymph nodes in surgical management of breast carcinoma.
2009
PURPOSE: In breast cancer staging, the need for intraoperative sentinel lymph node (SLN) evaluation has still not been adequately established. This study investigates the impact of intraoperative frozen section (FS) evaluation of SLN to avoid subsequent axillary lymph node dissection (ALND) in patients with positive SLN. METHODS: A retrospective review of 364 breast cancer patients undergoing SLN biopsy with intraoperative FS evaluation of SLN was performed. RESULTS: Sensitivity and accuracy of FS examination of SLN were 76.4% and 94.2%, respectively. The sensitivity was significantly higher in larger tumors (p < 0.01). No significant correlation was found between FS and histologic type. A …
Expanding the clinical spectrum of late-onset Pompe disease: Dilated arteriopathy involving the thoracic aorta, a novel vascular phenotype uncovered
2011
Abstract Purpose Cerebro-vascular arteriopathy has been reported in late-onset Pompe disease (LOPD). Evidence of increased aortic stiffness in some patients and smooth muscle involvement in LOPD raises the possibility of aortic involvement. Our aim was to determine if aortic arteriopathy may be a complication of LOPD. Methods One patient with LOPD was diagnosed with aortic dilatation at Duke Metabolic clinic, 4 others were diagnosed at University of Mainz, Germany, where chest X-ray and echocardiography are routinely done for patients. Other causes of aortic vascular disease were assessed. Results We report evidence of dilated arteriopathy involving primarily the ascending thoracic aorta in…
A comparison of transhiatal and transthoracic resections on the prognosis in patients with squamous cell carcinoma of the esophagus
2006
The aim of this study was to investigate the long-term prognosis for squamous cell carcinoma of the esophagus treated either by the transhiatal (TH) or by the transthoracic (TT) operative approach.Two hundred and twenty-nine patients (median age: 56 (29-84) years) with squamous cell carcinoma of the esophagus underwent esophageal resection between September 1985 and April 2004. In 70 patients, the transhiatal approach and in 159, the transthoracic approach was applied. An extended mediastinal lymph-node dissection was only carried out in the course of the transthoracic technique.Demographic data and tumor stages were comparable in both groups. A significantly better long-term survival was o…
Vaginal reconstruction with bilateral island "extended" groin flaps: description of a personal technique.
1994
We propose a vaginal reconstruction method using two island "extended" groin flaps designed over the iliac crests and in axis with the superficial circumflex iliac arteries. After a surgical revision of the pelvic organs and dissection of the area between the bladder and the rectum, the two flaps pass, extraperitoneally by way of the abdomen, through an incision made along the lateral margin of the rectus muscle and, from before to behind, through the fibrovascular lamina lateral to the bladder, and finally are placed in the area between the bladder and the rectum, where they are sutured. The technique has been applied to one patient and allowed reconstruction of a vaginal canal with very s…
Carcinoma of the neovagina: case report and review of the literature.
2001
Abstract Background. Carcinoma of the vagina is a rare disease, and it is even more rare in the neovagina. Nevertheless, it has been well described. The aim of this report was to analyze the reported cases and to add observations concerning a risk profile for this rare occurrence of carcinoma. Case report. The 29-year-old patient's history included congenital absence of vagina as a result of Rokitansky–Kuster syndrome. In 1987, when the patient was 17 years old, a neovagina was constructed by dissection between the bladder and the rectum, according to the Warthon method, and the apex of the neovagina was covered with Dura-mater. In 1990 the patient underwent radiation treatment with brachyt…
Bilateral vertebral artery dissection, agenesis of both ICAs, and connective tissue aberrations
2013
A 35-year-old woman presented with acute signs of stroke (appendix e-1 on the Neurology® Web site at [www.neurology.org][1]). After initial CT with angiography, MRI with time-of-flight angiography confirmed agenesis of both internal carotid arteries (ICAs; figure 1A). It revealed bilateral vertebral artery (VA) dissections and ischemias in both middle artery territories (figure 1, A–E). Skin biopsy microscopy (figure 2) was consistent with ultrastructural connective tissue disease (uCTD), for which no further evidence was found apart from mild hypermobility of the finger joints. The underlying uCTD with structural instability of the arterial walls and the increased blood flow in the vertebr…
Is it really useful the Harmonic scalpel in axillary dissection for locally advanced breast cancer? A case series.
2017
Background. The seroma is one of the most common complications in the axillary lymph nodal dissection (different surgical approaches have been tried to reduce the seroma incidence). In our study we evaluate the outcome of patients using or not the ultrasonic scalpel (Harmonic scalpel) according to a standardized surgical technique. Patients and Methods. From January 2011 to December 2015 120 patients underwent axillary dissection for breast cancer. Patients were divided in two groups: patients belonging to the first group underwent Harmonic scalpel dissection and patients belonging to the second group underwent classical dissection. Each group consisted of 60 patients. Quadrantectomy (QUAD)…
The role of dispositional and social factors in Argentinian and Spanish women's sexuality
2019
This study examines the role of sociocultural and dispositional factors in the sexual expressions of young Argentinian and Spanish women. Three hundred young women self-evaluated their sexual practices, sexual orientation, and relationships. Results reveal differences in women's sexuality based on societal and dispositional variables. The latter seem to play a more important role in those sexual behaviors that are normative in Hispanic traditions, whereas gender dissimilarity is more relevant when these behaviors are socially censured. Therefore, women's sexuality in Hispanic traditions, such as in Argentina and Spain, seems to be more complex than past studies reported.
