BACKGROUND: The purpose of this study is to decrease the incidence of venous congestion occurring in the reversed flow posterior interosseous artery flap used for coverage of hand defects. METHODS: This may be achieved by studying the incidence of venous congestion in flaps including only 1 perforator and comparing the results with others including more than 1 perforator both in small and large sized flaps. RESULTS: This study showed that inclusion of only 1 perforator in the flap decreased the incidence of venous congestion with complete flap loss in flaps to 5%...

Wild-type and variant forms of HpmA265 (truncated hemolysin A) from Proteus mirabilis reveal a right-handed, parallel β-helix capped and flanked by segments of antiparallel β-strands. The low-salt crystal structures form a dimeric structure via the implementation of on-edge main-chain hydrogen bonds donated by residues 243-263 of adjacent monomers. Surprisingly, in the high-salt structures of two variants, Y134A and Q125A-Y134A, a new dimeric interface is formed via main-chain hydrogen bonds donated by residues 203-215 of adjacent monomers, and a previously unobserved tetramer is formed...

BACKGROUND: Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue defects in the lower limb. METHODS: The study was carried prospectively and 23 patients with lower limb defects treated with various perforator flaps (both elective as well as emergency) were included in the study...

INTRODUCTION: Reconstruction has evolved long way from primary closure to flaps. As time evolved, better understanding of vascularity of flap has led to the development of innovative reconstructive techniques. These flaps can be raised from various parts of the body for reconstruction and have shown least donor site morbidity. We use one such peroneal artery perforator flap for tongue reconstruction with advantage of thin pliable flap, minimal donor site morbidity and hidden scar. MATERIALS AND METHODS: Our patient 57yrs old lady underwent wide local excision with selective neck dissection...

The augmented reality on smart glasses allows the surgeon to visualize three-dimensional virtual objects during surgery, superimposed in real time to the anatomy of the patient. This makes it possible to preserve the vision of the surgical field and to dispose of added computerized information without the need to use a physical surgical guide or a deported screen. TECHNIQUE: The three-dimensional objects that we used and visualized in augmented reality came from the reconstructions made from the CT-scans of the patients...

BACKGROUND: Few studies have been conducted to explore the use of the vacuum sealing drainage (VSD) technique in complex hand injuries. The aim of this study was to report outcomes in patients with complex hand injuries receiving VSD as a coadjuvant treatment prior to second-stage surgery. METHODS: This case series study retrospectively reviewed the patients who underwent VSD for treatment of hand injuries. Inclusion criteria for the study were: (1) traumatic soft tissue defects of the hand and wrist, accompanied by different degrees of injury and exposure of bone, tendon, or blood vessel; (2) the wound surface of hand and wrist was seriously contaminated and direct wound closure was not possible; and (3) the soft tissues of hand and wrist were seriously lacerated or avulsed, and showed necrosis or acute infection...

Individuals with Rett syndrome (RTT) can have variable manifestations of stereotypies. In this nation-wide cross-sectional study, we recruited all individuals with RTT in Taiwan diagnosed as RTT by neurologists based on genetic findings and diagnostic criteria. The data were collected using questionnaire. A total 43 cases of typical RTT and 15 cases of atypical RTT, aged from 2.1 to 40.1 years, were enrolled. They included 3 (5.2%) in stage II, 42 (72.4%) in stage III, and 13 (22.4%) in stage IV. All individuals presented with at least one stereotypy...

BACKGROUND: The skin on the lower leg has abundant perforators and, thus, is an excellent donor site for transplant tissue flaps. However, due to vascular variations and body positions, tissue flaps at the posterolateral proximal portion of the lower leg are rarely used for transplantation. This study reports our experience with the use of superficial lateral sural artery perforator (SLSAP) flaps in the repair of moderate-sized hand wounds. METHODS: From March 2012 to April 2015, the hand wounds of 15 patients were planned for repair using a superficial sural artery perforator flap...

Implantable microelectrode arrays (MEAs) usually have on-site electronics that need to be powered, both in neural recording and stimulation applications. Interconnecting wires between implanted electrodes and the outside world constitute a major source of complications. Our solution to this tethering problem is to design a light waveguide that can collect the optical power transcutaneously and transmit it to the microelectrode array where it is to be converted to an electric current. A polydimethylsiloxane (PDMS)-based waveguide was fabricated and its attenuation was measured in vitro and found to be 0...

Autism is a complex developmental disorder that affects approximately 1 in 68 children (according to the recent survey conducted by the Centers for Disease Control and Prevention-CDC) in the U.S., and has become the fastest growing category of special education. Each student with autism comes with her or his own unique needs and an array of behaviors and habits that can be severe and which interfere with everyday tasks. Autism is associated with intellectual disability, impairments in social skills, and physical health issues such as sleep and abdominal disturbances...

PURPOSE: A reverse-flow pedicled flap from the posterior interosseous artery (PIA) has been used to cover defects on the dorsal and volar aspects of the hand. However, the original description of this flap does not reach further than the metacarpophalangeal joints of the 4 ulnar digits. In the present study, we describe a distal variant (type 2) of the PIA flap, which changes the pivot point of the classic variant (type 1) and which can provide full coverage of single or multiple digits in the entire dorsum and palmar surface of the fingers...

Mutilated hand injuries are a profound challenge to the plastic surgeon, and such injuries often lead to limb loss and severe functional impairment. Hyperbaric oxygen therapy (HBOT) appears to counteract tissue hypoxia and stimulate acute wound healing. This study was performed to evaluate the efficacy of HBOT as an adjunctive therapy in patients with a mutilated hand injury. Between January 2006 and December 2014, 45 patients with a mutilated hand injury were enrolled. After reconstruction or revascularisation, patients underwent 120 minutes of HBOT with oxygen at 2·5 atmospheres absolute while breathing 100% oxygen...

Soft tissue defects of the thumb with exposure of tendons, periosteum, or neurovascular bundles require a complex reconstruction aimed at restoring both skin coverage and the essential function of pinching and manipulation. When large defects are involved, a free tissue transfer is indicated. The proximal ulnar perforator flap represents an interesting solution without the drawbacks of other more widespread free flaps. This report describes the case of a patient with a squamous cell carcinoma of the thumb that required circumferential resection of the soft tissue of the distal phalanx and the interphalangeal joint...

Lennert Van Putte, Steven D M Colpaert
BACKGROUND: Ptosis of the earlobe is a common consequence of ageing, defined as an unappealingly large free caudal segment of over 5 mm. It is therefore important to consider reduction as a complement to rhytidectomy in selected patients. Moreover, facelifting operations can result in disproportionate or poorly positioned earlobes. Current earlobe-reducing techniques can leave a scar on the free lateral edge causing notching or involve complex pattern excisions with limited resection capability and the risk of deformities...

Deep hand burns usually lead to joint and tendon exposure. A simple skin graft is insufficient to achieve healing. Soft tissue reconstruction represents a surgical challenge that ranges from the simplest to the most complex flaps. In some areas, microsurgery is not technically possible. Choice is then limited to pedicled distant flaps such as the abdominal wall flap-graft. We report a case of an acute burned hand with exposure of metacarpophalangeal joints from the second to the fourth radius as well as proximal inter phalangeal joints from the second to the fifth radius and extensor tendons, treated in the burns and wound care unit of the Sylvanus Olympio Teaching Hospital in Lomé...
