“The use of a dermal substitute and thin skin-grafts in the cure of complex leg ulcers”
No full textBACKGROUND In some chronic leg ulcers, a reconstructive operation using skin grafts may be extremely difficult or is quite likely to fail as a result of the position, the width, and the depth of the lesions.
OBJECTIVE To evaluate the effectiveness of a dermal substitute and thin skin grafts in the treatment of patients suffering from deep and wide chronic leg ulcers.
MATERIALS & METHODS Twenty-six consecutive patients with leg ulcers at least 1 year old were admitted to the study. The ulcers were large (4100 cm2) and deep (43mm) over at least 50% of the surface area. After surgical debridement of the wounds, the dermal matrix was modeled and applied. After 21 days, the attachment of the artificial dermis was tested, and in positive cases, the patient was
re-admitted for ‘‘thin’’ skin grafting.
RESULTS In all patients, at the first follow-up, a notable reduction in pain, exudate, and perilesional
edema was ascertained. After 2 weeks, the progressive substitution of granulation tissue with new yellow or gold derma became evident in all patients. After 21 days, the dermal matrix was completely integrated with the guest tissue. In 23 patients (88.5%), attachment of the skin graft was complete, and in three patients (11.5%), it was partial but nevertheless larger than 70% of the surface. Even in these cases, complete healing of the lesions was achieved within 4 weeks at most. All patients were checked for a minimum of 3 months, and none suffered an ulcerous recurrence.
CONCLUSION In our series, the use of this dermal matrix allowed for the complete refilling of the loss of tissue, the rapid disappearance of pain, and the rapid regeneration of a permanent dermis

Sutureless tension-free hernia repair with Human Fibrin Glue in soccer players with chronic inguinal pain: initial experience
No full textAbstract. Chronic groin pain is a common symptom experienced by soccer players, resulting in many athletes undergoing prolonged periods of conservative treatment. In a high proportion of these cases, however, the cause of groin pain is due to impalpable hernias, thus nullifying the usefulness of a conservative approach. Of the current surgical procedures for inguinal hernia repair, the Lichtenstein technique is widely used. The present study aims to evaluate the efficacy of mesh fixation with human fibrin glue (Tissucol) in open, tension-free inguinal repair, in the treatment of soccer players with groin hernia. A sutureless Lichtenstein technique was employed in 16 consecutive soccer players with primary groin hernia. Inguinal nerves were prepared and preserved. Human fibrin glue was used for mesh fixation, in place of conventional sutures. Results were rated as excellent in all cases, with no reported intra- or postoperative complications. All patients were discharged 4 - 5 h after the operation, and all returned to full pre-injury level sporting-activity, on average, 31 days (range 24 - 42 days) post surgery. This study confirms the efficacy of sutureless tension-free hernia repair with human fibrin glue for the treatment of soccer players suffering from chronic groin pain due to impalpable groin hernia

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
