Social demand for oral surgery in third age patients and its association with systemic pathologies
2010
Objectives: To determine the frequency of systemic pathologies in patients aged 65 years or more, who require oral care and possibly oral surgery. Study Design: We carried out a cross-sectional descriptive study reviewing 3,388 medical histories for patients from the Department of Medicine and Oral Surgery of the School of Dentistry at the Complutense University of Madrid, who had requested surgical treatment. Those selected were at least 65 years of age or more, and were grouped according to their medical histories into categories of pathologies, which include: systemic, cardiovascular, digestive, respiratory, endocrine-metabolic, genitourinary, osteoarticular, nervous system and the senso…
Low energy KTP laser in oral soft tissue surgery: A 52 patients clinical study
2011
Objectives: Since 1962 laser appliances have been used for soft tissues surgery of oral cavity with significant advantages compared to the traditional instruments: excellent bleeding control, possibility to avoid the use of suture, good patient compliance thanks to a decrease of intra- and post-operative discomfort and biostimulating effect. Unfortunately, the wavelengths so far used have been seen to cause, in association with an excellent ablation capacity, heat damage of the tissues that can decrease healing process and cause a greater discomfort to patients. The aim of this study was to evaluate the laser-assisted KTP laser surgery at low power in terms of characteristics of interventio…
A New Self-Expanding Nitinol Stent (JoStent SelfX) for Palliation of Malignant Biliary Obstruction: a Pilot Study
2004
Background and Study Aims: The JoStent SelfX is a new biliary uncovered self-expanding nitinol stent. The main advantage of this stent in comparison with the gold standard Wallstent is the minimal shortening (< 10%) that occurs during stent deployment. A prospective feasibility study was conducted to evaluate the method of stent implantation and the stent's short-term efficacy. Patients and Methods: Between April 2001 and December 2002, the JoStent SelfX was implanted in 20 patients with inoperable malignant biliary obstructions, mainly caused by pancreatic cancer (12 of 20). All patients underwent sphincterotomy prior to stent insertion. After implantation, laboratory parameters for choles…
Immediate effect of the MitraClip procedure on mitral ring geometry in primary and secondary mitral regurgitation.
2013
Percutaneous treatment of mitral regurgitation (MR) has been shown to reduce MR severity and improve functional outcomes. Surgical treatment of MR usually includes mitral annulus reduction. The influence of the MitraClip w on annulus geometry is not clear. We wanted to investigate whether the procedure itself reduces annulus diameter and if there may be differences between secondary or functional (SMR) and primary (PMR) MR. Methods and results We retrospectively assessed 3D echocardiography (3D-TEE) data of 55 patients acquired during the procedure shortly before and after clip placement for changes in annulus diameter and area. Measurements were done with QLAB software. Patients were categ…
Percutaneous Pedicle-Lengthening Osteotomy in Minimal Invasive Spinal Surgery to Treat Degenerative Lumbar Spinal Stenosis: A Single-Center Prelimina…
2018
Background Lumbar spinal stenosis (LSS) is a narrowing of the spinal canal due to spinal degeneration, and its main clinical symptom is neurogenic claudication. Surgical treatment is pursued for patients who do not improve with conservative care. Patients with symptomatic LSS who also have significant medical comorbidities, although clearly in need of intervention, are unattractive candidates for traditional open lumbar decompressive procedures. Thus it is important to explore minimally invasive surgical techniques to treat select patients with LSS. Methods This retrospective case series evaluated the clinical and radiographic outcomes of a new minimally invasive procedure to treat LSS: pe…
Management of Esophageal Perforations after Therapeutic Upper Gastrointestinal Endoscopy
1997
Esophageal perforation is one of the most dreaded complications in therapeutic gastrointestinal endoscopy. We assessed the frequency of esophageal perforation after endoscopic procedures in a highly specialized endoscopy unit and compared clinical outcomes in patients undergoing either surgical or conservative management.From January 1985 to June 1996, 1011 instrumental endoscopic procedures (dilatation and bougienage) were performed in our department. The computerized complication database was searched to identify all patients with esophageal perforation during this same period, and their records were reviewed.Seventeen esophageal perforations (1.7%) occurred in the course of 1011 procedur…
Endograft connector technique to treat popliteal artery aneurysm in a morbid obese patient.
2015
Surgical repair of popliteal artery aneurysm in morbid obese patients poses additional challenges. We report a morbid obese patient who had a 59 mm right popliteal artery aneurysm which was successfully treated with the endograft connector technique. This technique was used to perform the distal anastomosis of the below-knee femoro-popliteal bypass. A 10 mm Dacron graft was used as a main graft bypass and an 11 mm/10 cm stentgraft as endograft connector. Following the respective tunnel of the Dacron graft, an end-to-side proximal anastomosis was performed at distal femoral artery. The aneurysm exclusion was obtained through a proximal and a distal ligation. Postoperative duplex showed adeq…
Post Surgical Pyoderma Gangrenosum in flap surgery: diagnostic clues and treatment recommendations
2016
Background: Post Surgical Pyoderma Gangrenosum (PSPG) is a neutrophilic dermatosis causing aseptic necrotic ulcerations within surgical sites. It is often misdiagnosed as infection or ischemia and worsened by the inappropriate treatment. Therefore diagnostic clues must be identified and awareness for PSPG raised.Methods: We present two cases of PSPG after flap surgery and a review of the literature.Results: Seventeen cases of PSPG after flap surgery were found. Fever, pain and redness are the most common initial symptoms. In 63%, lesions were on the flap and the adjacent skin. In 63%, the donor site is also involved. Time to diagnosis was nine days to four years. Frequent debridement (89%) …
Pregnancy after syngeneic uterus transplantation and spontaneous mating in the rat.
2010
BACKGROUND: Uterus transplantation (UTx) research aims towards the introduction of UTx as a treatment for uterine factor infertility. The rat model is the principal rodent model used and this study aims to assess the potential for pregnancy and to assess effects on pregnancy outcome. METHODS: Female Lewis rats underwent hysterectomy and received syngeneic uterine transplants (with one horn removed) by end-to-side anastomosis between the common iliac vessels of the recipient and the graft. The graft was placed in an orthotopic position with anastomosis to the upper part of the native uterine horn and vagina to allow for pregnancy by mating. Controls had only one uterine horn removed. Mating …
Complications of trans-anastomotic externalised stents in open pyeloplasty: influence of the method of placement, the duration of stenting, and the a…
2010
To assess the influence of the method for stent placement, the duration of stenting, and the presence of bladder drainage on the complication rate of open pyeloplasty. Patients and methods: Complications were, retrospectively, compared in 228 consecutive open pyeloplasties performed at institution A using a trans-pyelostomic 6-Fr splint/stent for 5 days and no bladder drainage, and 150 consecutive open pyeloplasties performed at institution B using a trans-nephrostomic 6-Fr splint/stent for 9 days plus bladder drainage. Results: Median age at surgery was comparable between groups. The overall complication rate was 13% and was comparable at the two institutions, but for the presence of perio…
