Clinical evaluation of piezoelectric ear surgery
2008
We evaluated the use of piezoelectric surgery (Piezosurgery; Mectron Medical Technology; Carasco, Genoa, Italy) as a means of avoiding some complications of osteotomy and osteoplasty in otologic surgery, particularly in classic canal-wall-up mastoidectomy. Piezoelectric surgery is a recently developed system for cutting bone with microvibrations created by the piezoelectric effect. This effect occurs when an electric current is passed through certain ceramics and crystals, causing them to oscillate at ultrasonic frequencies. Our study population was made up of 20 adults with unilateral chronic otitis media. In all patients, piezoelectric surgery allowed for effective, precise, safe, easy, …
Dental trait anxiety and pain sensitivity as predictors of expected and experienced pain in stressful dental procedures.
2004
A prevailing hypothesis suggests that exaggerated pain expectations in dentally anxious and pain-sensitive patients might usually be disconfirmed by a lower level of pain experienced during treatment. The present study was conducted to investigate whether this contention also holds during stressful dental procedures. Patients reporting high and low levels of dental fear and of pain sensitivity were compared in their expected and experienced pain and in the concordance between the two measures. Participants were 97 patients undergoing extraction and root canal treatment. The measuring instruments used were the Dental Anxiety Scale (DAS), the Pain Sensitivity Index (PSI), affective and sensor…
Extra-Adrenal Adult Neuroblastoma With Aberrant Germ Cell Marker Expression: Maturation After Chemotherapy as an Important Clue to a Challenging Diag…
2019
Adult neuroblastoma is an extremely infrequent neoplasm, usually occurring in the adrenal medulla or in the paraspinal sympathetic ganglia, as its childhood counterpart. We report a very unusual case of a Schwannian stroma-poor adult neuroblastoma of inguinal location, showing aberrant expression of germ cell markers: SALL4 and OCT4. This aberrant marker expression, the unusual positivity for NKX2.2 and the very scattered (instead of diffuse strong) PHOX2B expression, complicated the initial diagnosis. In this case, the posttreatment histological evaluation revealed the neuroblastic nature of the lesion. Neuroblastoma maturation after treatment is an unusual finding in adults, and in this …
THE USE OF ARGENTUM-QUARTZ SOLUTION IN PRIMARY OR RECURRENT PERIANAL FISTULAS: FIRST EXPERIENCE ON THREE CASES
2019
Primary perianal fistulous pathology represents a painful condition often noticeable in patients affected by Crohn's disease or Ulcerative colitis. It causes difficult defecation and can evolve in perianal abscess that should be urgently ascertained and drained. The present work aims to propose Argentum-Quartz® as valid non-surgical therapeutic treatment in order to reach a more comfortable perianal fistula healing. In fact, our preliminary data allow us to consider Argentum Quartz® ideally employable for treatment of perianal fistulas associated or not with IBDs, representing a reliable sphincter-sparing solution.
Adaptation and validation of the Spanish self-report version of the Spinal Cord Independence Measure (SCIM III).
2014
Study design: This is a cross-sectional validation study. Objective: The objective of this study was to adapt and validate a self-report version of the Spinal Cord Independence Measure (SCIM III) for the Spanish population. Methods: A cross-cultural adaptation of the self-report version of the SCIM III for the Spanish population was performed on the basis of international guidelines. A total of 100 patients with spinal cord injury (SCI) were recruited. A team of healthcare professionals administered the SCIM III by observation. In addition, the patients completed the Spanish self-report version (eSCIM-SR). Data from both questionnaires were analysed jointly. Results: A high correlation was …
Early Results of Fissurectomy and Advancement Flap for Resistant Chronic Anal Fissure without Hypertonia of the Internal Anal Sphincter
2010
The aim of this study was to assess the efficacy of fissurectomy with skin advancement flap in healing chronic anal fissures without hypertonia of the internal anal sphincter. Twenty-six consecutive patients who failed healing after well-practiced topical medical therapy were enrolled. Anorectal manometry was performed preoperative and 6 months postoperatively. All patients were treated with fissurectomy and advancement flap through healthy skin tissue. All patients healed completely within 30 days from operation. The intensity and the duration of pain post-defecation was reduced significantly with respect to the preoperative values starting from the first defecation. One patient suffered …
Management of chronic otitis by middle ear obliteration with blind sac closure of the external auditory canal.
2008
Objective: Description of a technique of middle ear obliteration (MEO) with blind sac closure of the external auditory canal with discussion of the indications for its use in cases of recalcitrant chronic otitis and in far advanced disease. Patients: All patients underwent otologic examination and audiologic and radiologic assessments in a quaternary center. Results: Fifty-three cases of MEO were analyzed. For 9 patients, primary surgery was performed. One case of residual disease was identified. The minimum follow-up was 2 years. Conclusion: The decision to perform a MEO is one that is made only rarely. However, this is a technique that should be part of every otologist`s armamentarium. Wh…
A minor modification of Lichtenstein repair of primary inguinal hernia: postoperative discomfort evaluation.
2010
The aim of this study was to evaluate the usefulness of a modification of the Lichtenstein hernioplasty procedure by evaluating its impact on postoperative discomfort. From December 1999 to May 2006, the Lichtenstein inguinal hernioplasty was performed in 406 patients with noncomplicated unilateral inguinal hernia. During reconstruction, the mesh was fixed to the inguinal canal floor without stitching its upper margin to the internal oblique muscle. Control of postoperative pain proved to be satisfactory; 72 hours after surgery, 26.1 per cent of patients no longer felt any pain, whereas 54.4 per cent had slight pain without the need for painkillers; on Day 7, 92.8 per cent felt no pain at …
Radical surgery and different types of urinary diversion in patients with rhabdomyosarcoma of bladder or prostate--a single institution experience.
2013
Abstract Purpose In a retrospective study we analyzed the outcome of patients treated for rhabdomyosarcoma (RMS) of the bladder/prostate with special attention to radical surgery. Methods In 25 patients with genitourinary RMS (15 bladder/10 prostate) the median age at diagnosis was 4 years [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , and 8 patients had a stage II RMS, 12 stage III and 5 stage IV. In 19/25 (12 bladder/7 prostate), radical surgery and urinary diversion were performed. Urinary diversion comprised 2 continent anal diversions, 11 continent cutaneous diversions, 4 colon conduits and 2 urethral diversions (2 +…
Autogenous tooth transplantation : evaluation of pulp tissue regeneration
2010
Objective: The aim of this study was to assess the pulp survival that occur in transplants of autologous teeth, by comparing two surgical techniques: the conventional technique (autotransplantation for newly formed alveoli), and an alternative technique, (autotransplants for alveoli in the initial phase of healing). In each surgical techniques were applied, randomly, either saline solution or Emdogain ®. Study Design:The study group comprised 26 patents, in which 28 teeth were transplanted to recipient sockets prepared mechanically. Of the 28 teeth transplanted, 4 were intentional replants, and of the remainer, 11 had the apex closed and 13 open. The mean age at the time of transplantation …
