Liver transplanted patients with preoperative autoimmune hepatitis and immunological disorders are at increased risk for Post-Transplant Lymphoprolif…
2010
Long term immunosuppression and therapy of acute rejections result in a 20-120-fold increased risk to develop Non Hodgkin lymphoma (NHL). Since immunosuppressive therapy and immunological disorders are major risk factors for the development of NHL in the non-transplant population we aimed to analyze risk factors for PTLD in our cohort of liver transplanted (LT) patients.We analyzed retrospectively 431 patients liver transplanted between 1998 and 2008.PTLD was diagnosed in eleven of 431 patients (2.6%). PTLD, especially late PTLD, was significantly more frequent in patients who received steroids before LT (Kaplan-Meier: p0.001). Moreover PTLD in immunocompromised patients with preoperative s…
Simple endoscopic decompression of cubital tunnel syndrome with the Agee system: anatomic study and first clinical results.
2010
BACKGROUND Simple decompression in ulnar nerve compression syndromes offers options for endoscopic applications. OBJECTIVE The authors present their initial experience with the Agee device. PATIENTS AND METHODS The monoportal endoscopic technique (Agee system) was evaluated on 10 cadaveric arms. Subsequently, 32 arms of 29 patients were operated on between January 2006 and March 2009. All patients presented with typical clinical signs and neurophysiologic studies. Long-term follow-up examinations were obtained in 27 of 32 arms. RESULTS In the cadaver study, the ulnar nerve was always correctly identified. No nerve damage occurred, and sufficient decompression of the ulnar nerve was always a…
Inflammation and endothelial activation are linked to renal function in long-term kidney transplantation
2006
The aim of this study was to investigate the relationships between inflammation and adhesion molecules in long-term kidney transplantation. We measured serum concentrations of tumor necrosis factor-alpha (TNFalpha) and intercellular and vascular cell adhesion molecules (ICAM-1 and VCAM-1) in 35 renal transplant recipients (mean age of transplantation 5 +/- 3 years) and in 35 chronic renal insufficiency (CRI) patients; twenty-six healthy subjects were enrolled as controls. Transplanted showed higher values than controls of TNFalpha (P < 0.0001), ICAM-1 (P < 0.0001), and VCAM-1 (P < 0.0001). CRI group as well exhibited higher concentrations than controls of TNFalpha (P < 0.0001), ICAM-1 (P < …
Allogenic simple limbal epithelial transplantation (alloSLET) from cadaveric donor eyes in patients with persistent corneal epithelial defects
2020
Background/aimTo describe the clinical outcome of allogenic simple limbal epithelial transplantation (alloSLET) utilising tissue from cadaveric donor eyes after failed re-epithelialisation of the corneal surface.MethodsMedical records of 14 eyes from 14 patients treated for persistent corneal epithelial defects with alloSLET were reviewed. The primary outcome measure was complete epithelialisation of the corneal surface. Secondary outcome measures were best corrected visual acuity (BCVA) and postoperative side effects due to surgery or medical therapy.ResultsOf the 14 eyes, 7 received alloSLET only and 7 alloSLET together with penetrating keratoplasty (PK). Thirteen (92.9%) of 14 eyes had a…
Real-time control for transscleral cyclophotocoagulation.
1998
• Background: In transscleral cyclophotocoagulation, the surgeon cannot directly observe the applied laser effects. Overdosage, possibly resulting in unwanted pop effects, or underdosage with no therapeutic effect therefore often occur. • Method and materials: Laser radiation passing through the sclera and ciliary body is partly reflected from the fundus and can be monitored from outside the eye by a detector system. Since all other parameters influencing the intensity of the recorded radiation are constant in time during one laser exposure, the time dependence of this radiation directly reflects the change of transmission of the treated tissue. The laser exposure therefore can be stopped b…
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…
Superior pedicle retroauricular island flap for ear and temporal region reconstruction: anatomic investigation and 52 cases series.

Superior pedicle retroauricular island flap for ear and temporal region reconstruction: anatomic investigation and 52 cases series. Cordova A, Pirrello R, D'Arpa S, Moschella F. Source Cattedra di Chirurgia Plastica e Ricostruttiva, Dipartimento di Discipline Chirurgiche ed Oncologiche, Università degli Studi di Palermo, Palermo, Italy. adriana.cordova@excite.com Abstract BACKGROUND: On the basis of a previously published anatomic study on the superior auricular artery (SAA) and on a series of 52 consecutive cases, the authors propose a new superior pedicle retroauricular island flap (SP-RIF) for defects of the upper half of the ear and for temporal region or superficial helical defects.

A ballistometer for the study of the plasto-elastic properties of skin.
1977
The ballistrometer is based on the "drop impact" of a body onto a stationary surface. A collision in one dimension is provoked by allowing a bard body to drop from a given height onto the skin surface to be tested. After the collision, the impacting body undergoes a variable number of rebounds decreasing in amplitude. By measuring the height of the rebounds, the amount of energy returned by the tissue is calculated in terms of coefficient of restitution e. The equipment, consisting of a hammer unit, a feeder-amplifier, and a plotter, is described. Ballistometry has been carried out on skin areas of 46 normal subjects ranging in age from 8 to 80 years, as well as on pathologic and cadaveric …
Surgical Anatomy of the Rectovaginal Space: Does a Standalone Rectovaginal Septum or Denonvilliers Fascia Exist in Women?
2021
Background Below the anterior peritoneal reflection, the anterior rectal wall and mesorectum are separated from the posterior vaginal wall by a virtual rectovaginal space. In this space, the description of a specific and independent rectovaginal septum as a female counterpart of Denonvilliers fascia has been the subject of debate over the years. Objective The aim of this study is to perform an accurate anatomical study of the rectovaginal area in a cadaveric simulation model of total mesorectal excision to evaluate the possible structures and the dissection planes contained within the rectovaginal space. Design and setting This is a cadaveric study performed at the University of Valencia. P…
