Vacuum-Assisted Closure for the Treatment of Fournier’s Gangrene

Background: Fournier’s gangrene (FG) is a very aggressive necrotizing fasciitis involving subcutaneous fat and skin of scrotal and perineal regions. Vacuum-assisted closure (VAC) is a well-known method used to treat complex wounds. The authors for the first time enhance a multimodal strategy to treat the FG using VAC, reducing the number of surgical debridements, allowing a one-step surgical reconstruction with locoregional fasciocutaneous flap. Methods: Six patients with the diagnosis of FG were reviewed retrospectively at our institution. All patients were affected by very extensive FG. The FG Severity Index (FGSI) was used to evaluate the prognosis of the case at admission. Following the acute phase (24–48 h), VAC was used to achieve wound cleaning and prepare the area to a single-stage reconstruction with superomedial thigh flap. Hyperbaric oxygen therapy was also used before final reconstruction. Results: The average FGSI was 10.5, ranging from 8 to 12. All patients survived and were completely healed at the mean follow-up time of 9 months (range 3–30 months). Conclusions: VAC therapy is effective to clean and prepare the wounds, cutting off the fasciitis process and reducing the hospital stay and patient discomfort. Multidisciplinary treatment is mandatory during this devastating infection.

Elevator Muscle Anterior Resection: A New Technique for Blepharoptosis.

AbstractBlepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

AAV vector encoding human VEGF165–transduced pectineus muscular flaps increase the formation of new tissue through induction of angiogenesis in an in vivo chamber for tissue engineering: A technique to enhance tissue and vessels in microsurgically engineered tissue

In regenerative medicine, new approaches are required for the creation of tissue substitutes, and the interplay between different research areas, such as tissue engineering, microsurgery and gene therapy, is mandatory. In this article, we report a modification of a published model of tissue engineering, based on an arterio-venous loop enveloped in a cross-linked collagen–glycosaminoglycan template, which acts as an isolated chamber for angiogenesis and new tissue formation. In order to foster tissue formation within the chamber, which entails on the development of new vessels, we wondered whether we might combine tissue engineering with a gene therapy approach. Based on the well-described tropism of adeno-associated viral vectors for post-mitotic tissues, a muscular flap was harvested from the pectineus muscle, inserted into the chamber and transduced by either AAV vector encoding human VEGF165 or AAV vector expressing the reporter gene β-galactosidase, as a control. Histological analysis of the specimens showed that muscle transduction by AAV vector encoding human VEGF165 resulted in enhanced tissue formation, with a significant increase in the number of arterioles within the chamber in comparison with the previously published model. Pectineus muscular flap, transduced by adeno-associated viral vectors, acted as a source of the proangiogenic factor vascular endothelial growth factor, thus inducing a consistent enhancement of vessel growth into the newly formed tissue within the chamber. In conclusion, our present findings combine three different research fields such as microsurgery, tissue engineering and gene therapy, suggesting and showing the feasibility of a mixed approach for regenerative medicine.

The reasons for end-to-side coaptation: how does lateral axon sprouting work?

Nerve fibers are attracted by sutureless end-to-side nerve coaptation into the recipient nerve. Opening a window in the epineurium enhances axon attraction and myelination. The authors analyze the features of nerve repair by end-to-side coaptation. They highlight the known mechanisms of axon sprouting and different hypotheses of start up signals (presence or absence of an epineurial window, role of Schwann cells, signaling from the distal trunk). The clinical literature is also presented and differences between experimental and clinical applications are pointed out. The authors propose their point of view and perspectives deriving from recent experimental and clinical experiences.

Lipofibromatous hamartoma of the median nerve: 3T MRI evaluation by constrained spherical deconvolution analysis

In this study we described a case of lipofibromatous hamartoma involving the median nerve. We adopted diffusion tensor imaging and constrained spherical deconvolution-based tractography to reconstruct the affected median nerve. Moreover, we extracted diffusion-based parameters reflecting axonal integrity loss of median nerve fibres. Our data showed that constrained spherical deconvolution-based tractography outperformed the diffusion tensor imaging-based method, allowing the detection of the entire median nerve, including its branches, thus offering a robust method to investigate the involvement of the median nerve in pathological conditions. All clinical and technical implications are extensively described.

Mastopexy with Implants

Breast ptosis occurs as a physiological downward dislocation of the breast as an effect of pregnancy and lactation in young women, or as a postmenopausal reduction of estrogen in the elderly. Certain medications, weight gain or loss, and genetic predisposition can also contribute to the development of ptosis.

Diffusion Tensor Imaging Tractography in Pure Neuritic Leprosy: First Experience Report and Review of the Literature

Five years after both right ulnar and median nerve decompression for paraesthesias and palsy, a patient, coming from Nigeria but living in Italy, came to our unit claiming to have persistent pain and combined median and ulnar palsy. Under suspicion of leprosy, skin and left sural nerve biopsy were performed. Skin tests were negative, but Schwann cells resulted as positive for acid-fast bacilli (AFB), leading to the diagnosis of Pure Neuritic Leprosy (PNL). The patient was given PB multidrug therapy and recovered from pain in two months. After nine months both High Resolution Ultrasonography (HRUS) and Magnetic Resonance Imaging (MRI) were performed, revealing thickening of the nerves. Since demyelination is common in PNL, the Authors started to use Diffusion Tensor Imaging Tractography (DTIT) to get better morphological and functional data about myelination than does the traditional imaging. DTIT proved successful in showing myelin discontinuity, reorganization, and myelination, and the Authors suggest that it can give more information about the evolution of the disease, as well as further indications for surgery (nerve decompression, nerve transfers, and babysitting for distal effector protection), and should be added to traditional imaging tools in leprosy.

Anatomical and aesthetical reconstruction of complex hair-bearing areas: a three-step procedure including implant of dermal regeneration templates, skin grafting, and hair micrografting.

AbstractReconstructive surgery of complex hair-bearing skin defects often represents a challenge for the plastic surgeon; indeed, a multistage procedure is to be planned, including a first reconstructive step including local flaps, even if pre-expanded, or for larger defects, microsurgical flaps. To date, the implant of dermal regeneration templates has been proven an effective alternative. The authors relate their results of a complex hair-bearing reconstruction of a scalp and brow defect after a friction road burn with those reported in literature, concluding that a 3-staged reconstruction (dermal template implantation, skin grafting, and finally hair micrografting) can achieve good results in this complex kind of reconstruction. Histological specimens taken 2 years later confirmed a full anatomical reconstruction of the hair-bearing areas. Finally, this paper reports the first case of brow reconstruction performed with these techniques.

Language Test for Accreditation: the experience of C.L.A.M. (Language University Centre, Messina).

Since June 2004, C.L.A.M. has introduced a language test for accreditation for University students wholly created, administered and delivered in electronic format. C.L.A.M.’ s target users include mainly University students who need to take a test in a foreign language, such as English, German, French and Spanish to get credits for their linguistic competence in receptive skills (i.e. listening and reading comprehension, including grammar and vocabulary). In the last exam session, almost 300 students per day were evaluated in a multimedia lab with 50 PCs connected by an Intranet. During the four annual exam sessions, students can log into online simulations and exercises via C.L.A.M. website (also available via mobile version through PocketPC) creating a flow of almost 20.000 visited pages (almost 150 unique accesses per day) in the period considered. This paper illustrates technicaloriented choices underlying the creation of the standard for the tests, specific tools, automation processes – from students’ subscription to the exam – and the making of on-line simulations, exercises and tests supported by QuestionMark platform software Perception. The procedure for the creation of the different parts of the test will be displayed, highlighting pros and cons of Perception, integration of multimedia objects and the software created by our Language Centre for automatic publishing of original materials produced by Item Writers directly in .doc and .txt extension. Furthermore, the various phases which each student has to accomplish will be analysed also considering the solutions, related to the automation, security and monitoring of operations.
