BACKGROUND: Entrapment of the superficial sensory branch of the radial nerve (SRN) commonly results in debilitating pain of the dorsoradial wrist. Symptom relief following SRN neurolysis is often incomplete or temporary due to recurrent perineural scarring. METHODS: We performed a retrospective review with prospective follow-up of all patients with SRN neuropathy who were treated with neurolysis and nerve wrapping using an amnion-based allograft adhesion barrier over a one-year interval...

The free radial forearm flap is considered as the gold standard in penile reconstruction for good functional and aesthetic results. The scar on donor site could be considered as pathognomonic of their situation by transsexual patients. The development of microsurgical flaps provides new therapeutic options. This options are discussed and a therapeutic algorithm is presented. The main techniques used are the pedicled anterolateral thigh perforator flap and free muscle sparing latissimus dorsi flap. Principal criteria are listed, the choice of patient and the local anatomical conditions are the most important...

RATIONALE: A pedicle pectoralis major musculocutaneous (PMMC) flap is one of the strategies for head and neck reconstruction. Seldom studies reported the case in which the skin area of previous modified radical mastectomy (MRM) had been used as a PMMC flap in head and neck reconstruction. PATIENT CONCERNS: An 84-year-old female who had suffered from left breast cancer and undergone a left modified radical mastectomy (MRM) more than 20 years earlier. DIAGNOSES: She had squamous cell carcinoma of the tongue and had undergone partial glossection and left modified radial neck dissection...

The control of spatial and polarization modes of optical beams enables the production of topological singularities encoded on the polarization of the light. This allows the study of topological disclinations not easily found in the natural setting. In this article we report on the observation of new features in disclinations realized with singular optical beams. They were prepared using three spatial modes bearing optical vortices in non-separable superpositions with circular polarization states. The disclinations involve asymmetric rotational dislocations, whose optical counterparts in the optical far field are known as C-points, and which are classified as monstars...

RATIONALE: Elbow injury in children by improper treatment or a delay of more than 3 weeks could lead to old unreduced Monteggia fracture, which are difficult to manage. Conservative or normal surgical methods usually fail. PATIENT CONCERNS: Herein, we present a 6-year-old boy with sustaining injury approximately 1 month to his left elbow. Activity in his elbow was restricted, and his ability to extend his wrist and fingers was impaired. DIAGNOSES: Type III Monteggia elbow fracture-dislocation consisting of radial head dislocation and malunion of the ulna associated with posterior interosseous nerve palsy were confirmed, which requiring surgical treatment...

Rubber band syndrome is a rare entity seen in younger children mainly in communities where rubber bands are worn around the wrist for decorative purposes. When the band is worn for a long duration, it burrows through the skin and soft tissues resulting in distal edema, loss of function, and even damage to the neurovascular structures. These symptoms are difficult to relate to this rare but typical condition. We report a case of a 2¾-year-old girl with the history of a linear circumferential scar at the right wrist combined with the limited use of a swollen hand for several weeks...

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...

INTRODUCTION: Breast radial scar (RS) management remains controversial. The need for surgical excision is supported by the concern of an associated high-grade lesion missed in the biopsy. The aim of this study was to assess histologic upgrade rate after a percutaneous biopsy, to determine if vacuum assisted biopsy prevents the need for subsequent RS surgical resection and to evaluate the upgrade risk factors. PATIENTS AND METHODS: This was a uni-institutional retrospective study of consecutive patients with RS histologically diagnosed from January 2010 to December 2015...

In humans and other mammals, the neural retina does not spontaneously regenerate, and damage to the retina that kills retinal neurons results in permanent blindness. In contrast to embryonic stem cells, induced pluripotent stem cells, and embryonic/fetal retinal stem cells, Müller glia offer an intrinsic cellular source for regenerative strategies in the retina. Müller glia are radial glial cells within the retina that maintain retinal homeostasis, buffer ion flux associated with phototransduction, and form the blood/retinal barrier within the retina proper...

When coherent charge carriers cross micron-scale cavities, their dynamics can be governed by a few resonant states, also called "quantum scars", determined by the cavity geometry. Quantum scars can be described using theoretical tools but have also been directly imaged in the case of high-quality semiconductor cavities as well as in disordered graphene devices, thanks to scanning gate microscopy (SGM). Here, we discuss spatially resolved SGM images of low-temperature charge transport through a mesoscopic ring fabricated from high-quality monolayer graphene lying on top of hexagonal boron nitride...

BACKGROUND: Fibrin clot formation, which acts to stabilize a wound following injury, is among the key early aspects of dermal wound healing. This preliminary matrix is eventually degraded via a process known as fibrinolysis and replaced with a collagen-rich matrix that continues to be remodeled to minimize scarring. Disruptions in these carefully coordinated events lead to certain undesirable conditions such as fibrosis and the formation of abnormal scars that are associated with excess amounts of collagen...

PURPOSE: In contemporary practice, 5% of women with non-malignant needle biopsies of screen-detected lesions still require diagnostic open biopsy (OBx). Our aims are to (i) capture a snapshot of the contemporary indications for OBx in screen-detected lesions; (ii) determine upgrade rates to malignancy (DCIS or invasive cancer); (iii) identify indications with sufficiently low upgrades to justify avoidance of OBx and (iv) propose plausible non-surgical alternatives. METHODS: Between Jan 2005 and Dec 2014, women assessed for a screen-detected lesion and recommended for OBx are included...

Since a few years, the transoral robotic surgery reduced the morbidity of oropharyngeal tumors excision. Large posterior tumors can now be removed without any scar visible on the face. In this context and to respect the thinness required for reconstructions at the junction of the upper aerodigestive tract, the free radial forearm flap still remains the solution of choice. However, if the transoral robotic surgery respects the anatomy and the aesthetics of patients at the visible and social area that represents the face, the forearm flap provides visible scars on the other region of social interaction that represents the upper limb...

REVIEW

The anterolateral thigh (ALT) perforator flap for phalloplasty is gaining popularity because it avoids the well-known scars of the radial forearm flap. However, scars are not eliminated, just moved to a different location, the thigh, that can for some patients be of great sexual value. Preexpansion of the ALT flap allows primary donor site closure, thus avoiding not only the unsightly appearance of a skin grafted ALT donor site, but also the skin graft donor site scar. Preoperative perforator location by means of computed tomography angiography allows safe expander placement through 2 small remote incisions...

BACKGROUND: The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. METHODS: A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy...

Percutaneous imaging-guided core needle biopsy (CNB) is a less invasive and less expensive alternative to surgical biopsy for the evaluation of breast lesions. After a CNB the radiologist determine if there is concordance between the pathology, imaging, and clinical findings. Patient management after CNB diagnosis of high-risk breast lesion varies. Surgical excision is warranted for lesions yielding a CNB diagnosis of ADH; however controversy exists regarding the need for surgical excision after CNB diagnosis of radial scar, papillary lesion, atypical lobular hyperplasia (ALH), or lobular carcinoma in situ (LCIS)...
