Treatment of pressure ulcers in patients with spinal cord injury: Conventional surgery vs. cellular therapy.

Context: Relapse and recurrence rates of pressure injuries (PIs) are very high in spinal cord injured patients. That is the reason why alternative therapies, such the stem cells derived from bone marrow, have been developed.

Objective: To compare this new technique of infiltration-infusion of mononuclear cells from bone marrow with conventional surgery.

Keratocyst Capnocytophaga superinfection.

Introduction: Capnocytophaga spp are Gram-negative bacteria that cause severe infections in immunosuppressed patients. This situation is extremely rare in immunocompetent patients.

Case Report: This clinical report describes the unusual infection of an immunocompetent patient with Capnocytophaga spp.

Use of Integra in oral reconstruction: a case series.

Objective: Small intraoral defects are usually reconstructed using skin autografts. However, the goal of this research was to describe an alternative to classic techniques using artificial dermis (Integra) in the reconstruction of these types of injuries.

Materials And Methods: Four patients with small intraoral lesions in different locations underwent resection.

Regeneration of mandibular defects using adipose tissue mesenchymal stromal cells in combination with human serum-derived scaffolds.

Bone regeneration is a challenging issue. Traditional solutions bring risks, potential complications, and morbidity. The aim of the present study was to regenerate critical-sized mandible defects in athymic rats with adipose tissue mesenchymal stromal cells (AT-MSCs) in combination with human serum-derived scaffolds.

[XXV Anniversary of the Endoscopy-Lithiasis-Laparoscopy (LEL) Working Group].

Introduction: The purpose of this article is to describe the structural vicissitudes and content changes experienced by our Work Group, LEL over the last twenty-five years.

Materials And Methods: The compiled material comes from three sources: the author's experiences; the iconography provided by the co-ordinators; and the data obtained from programmes, letters, etc. This material has been analyzed and organized into six stages and the following has been highlighted in each of these: specific data from each day; key structural data; and the most relevant facts during the period.

[Lasers in urology].

Unlabelled: The objective of this article is to quote under the form of a document the opinions expressed by the participants of the round table "Lasers in Urology Today" (january 2006). The material and method used is the compilation of critical and updated notions on the usefulness of lasers in urology, supplemented by bibliographic references, a limited iconography. The results achieved by lasers today enable us to state that: Holmium laser is the choice treatment for in situ lithotripsy; however, it has not significantly improved previous results when treating urologic tumours and stenoses.

Sebaceous adenoma of the parotid gland.

Tumors of the salivary glands constitute an important field of oral and maxillofacial pathology. The majority of salivary gland neoplasms are benign, with malignant salivary tumors accounting for 15 to 32 percent. The most common site for salivary gland tumors is the parotid gland, accounting up to 80 percent of all cases.

Maxillofacial cellulitis.

Of all infections associated to oral pathology, the most relevant ones are those that are related to dental pathology. Cellulitis is an infection of the cellular adipose tissue located in the aponeurotic spaces. It can be classified on the basis of location, severity and evolution.

Consensus statement on antimicrobial treatment of odontogenic bacterial infections.

The infection of the oral cavity is a common public health problem and constant cause for antibiotic prescription, with 10% of antibiotics used to treat this problem. However, few studies have so far aimed to determine its incidence. Added to this, its relationship with certain sytemic diseases (cardiac, endocrine, etc) confers this pathology vital importance.

[Radical or conservative surgery for upper urinary tract transitional cell carcinomas (TCC)?].

Objective: We expose the arguments supporting radical and conservative surgery based on international bibliography and our own experience, with special citation of endoscopic surgery (percutaneous and ureteroscopy).

Methods/results: We evaluate the criteria of multifocality, cell seeding and number of recurrences separately, as well as the diagnostic difficulties establishing tumor grade and stage, by connecting the various techniques and their results.

Conclusion: the choice between radical or conservative surgery for upper urinary tract TCC is conditioned by precise indications and the surgical technique chosen does not influence the final outcome of low grade/stage tumors.

Treatment of oral and oropharyngeal epidermoid carcinomas by means of CO2 laser.

Introduction: The effect of the wide long-wave CO2 laser is the thermal vaporization of the tissues, getting a maximum energy concentration with a minimum of tissue penetration. In oral surgery, it is generally used for the treatment of oral and oropharyngeal small mucous tumors, due to the scarce morbidity that takes place and the absence of reconstructive necessity.

Objective: To analyze the postoperative evolution, in the patients treated by oral and oropharyngeal epidermoid carcinomas, after CO2 laser resection.

Neck schwannomas.

Schwannomas are peripheral nerve tumours of nerve sheath origin. Twenty-five to 45 percent of extracranial schwannomas occur in the head and neck region. We present 2 cases of schwannomas that arise from the vagus and cervical plexus.
