BACKGROUND CONTEXT: Whilst most cadaveric studies of the RLN have focused on course variations, they have usually been done on preserved (fixed and embalmed) cadavers which renders the RLN immobile and of less surgical landmark value. PURPOSE: Our aim was to perform a thorough exposure in fresh cadavers with the intention of investigating inferior thyroid artery and Berry's ligament as reliable landmarks for the identification of the RLN in anterior cervical spine surgery...

INTRODUCTION: Treatment of moderate to severe slipped capital femoral epiphysis (SCFE) is controversial. Over the last years, 3 institutions in Argentina adopted the modified Dunn procedure for capital realignment in selected cases of SCFE. Our aim in this study was to evaluate the clinical outcome and the rate of complications of patients who had undergone surgical hip dislocation and capital realignment. METHODS: A multicenter retrospective cohort study of patients who received the modified Dunn procedure from January 2009 to 2013 was performed...

: Neuronal activity plays a key role in the development of sensory circuits in the mammalian brain. In the gustatory system, experimental manipulations now exist, through genetic manipulations of specific taste transduction processes, to examine how specific taste qualities (i.e., basic tastes) impact the functional and structural development of gustatory circuits. Here, we used a mouse knock-out model in which the transduction component used to discriminate sodium salts from other taste stimuli was deleted in taste bud cells throughout development...

INTRODUCTION: Postmastectomy pain syndrome (PMPS) is a significant burden for breast cancer survivors. Although multiple therapies have been described, an evolving field of serratus anterior plane blocks has been described in this population. We describe the addition of the deep serratus anterior plane block (DSPB) for PMPS. METHODS: Four patients with history of PMPS underwent DSPB for anterior chest wall pain. A retrospective review of these patients' outcomes was obtained through postprocedure interviews...

Jie Li, Mark L Baccei
: It is well-established that sensory afferents innervating muscle are more effective at inducing hyperexcitability within spinal cord circuits compared to skin afferents, which likely contributes to the higher prevalence of chronic musculoskeletal pain compared to pain of cutaneous origin. However, the mechanisms underlying these differences in central nociceptive signaling remain incompletely understood, as nothing is known about how superficial dorsal horn (SDH) neurons process sensory input from muscle vs...

An injectable local anesthetic producing repeatable on-demand nerve block would be desirable for pain management. Here we present a phototriggerable device to achieve repeatable and adjustable on-demand local anesthesia in superficial or deep tissues, consisting of gold nanorods attached to low temperature sensitive liposomes (LTSL). The particles were loaded with tetrodotoxin and dexmedetomidine. Near-infrared light (NIR, 808 nm, continuous wave) could heat gold nanorods at low fluence (short duration and low irradiance), leading to rapid release of payload...

REVIEW
Betül Tuğcu, Hakan Özdemir
Optic disc drusen (ODD) are benign congenital anomalies of the optic nerve characterized by calcified hyaline bodies. While superficial drusen can be diagnosed easily during fundus examination, detecting buried drusen requires the use of additional imaging methods such as B-scan ultrasonography (USG), fundus fluorescein angiography (FFA), computed tomography (CT) and fundus autofluorescence (FAF). ODD can be detected by USG with the presentation of highly reflective round structures. ODD appear as hyperautofluorescent areas on FAF and bright spots on CT scans...

The presence of an accessory muscle in the forearm is likely to compress on the neurovascular structures and has clinical implications. We encountered an accessory humeral head of pronator teres during routine dissection of left upper limb in a male cadaver. The accessory head had fleshy origin from medial supracondylar line, medial intermuscular septum and brachialis fascia. It coursed downwards in the cubital region covering brachial artery and median nerve. Further, it narrowed becoming mostly tendinous and joined with the humeral head of pronator teres...

PURPOSE: To evaluate the transillumination test in showing the position of the superficial peroneal nerve (SPN) to quantify the effectiveness of this test. METHODS: Prospectively, we selected 53 ankle arthroscopy patients (71 patients were excluded because of the invisible SPN). Demographic data including gender, weight, height, and body mass index were recorded. The intraoperative transillumination test was performed during portal establishment and recorded as positive if the SPN was visible via transillumination...

OBJECTIVE: Challenges persist in the reconstruction of the ankle and the foot with exposed tendons, joints, and bones as a result of severe burns and trauma. In flap elevation involving the sensitive superficial nerve, the local nerve was always sacrificed to obtain an anesthetic donor site; however, such a procedure introduced the possibility of painful neuromas. In this study, we present a desired clinical application of a modified reversed superficial peroneal artery flap, in which the superficial peroneal nerve is preserved...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

A seven-month old female presented with left tibial hemimelia (or congenital tibial aplasia; Weber type VIIb, Jones et al type 1a), seven-toed preaxial polydactyly, and severe club foot (congenital talipes equinovarus). Definitive amputation surgery disarticulated the lower limb at the knee. This case report describes the anatomical findings of a systematic post-amputation examination of the lower limb's superficial dissection, X-rays, and computed tomography (CT) scans. From the X-rays and CT scans, we found curved and overlapping preaxial supernumerary toes, hypoplastic first metatarsal, lack of middle and distal phalanges in one supernumerary toe, three tarsal bones, hypoplastic middle phalanx and no distal phalanx for fourth toe, and no middle or distal phalanges for fifth toe...
