Most current cartilage testing devices require the preparation of excised samples and therefore do not allow intra-operative application for diagnostic purposes. The gold standard during open or arthroscopic surgery is still the subjective perception of manual palpation. This work presents a new diagnostic method of ultrasound palpation (USP) to acquire applied stress and strain data during manual palpation of articular cartilage. With the proposed method, we obtain cartilage thickness and stiffness. Moreover, repeated palpations allow the quantification of relaxation effects...

The purpose of this study was to present the management of a series of patients referred with infraorbital nerve paraesthesia that developed after insignificant orbital floor fracture without diplopia or exophthalmos, and that did not require initial surgical repair. This is a retrospective interventional case series. The main outcome and measures were assessment of preoperative symptoms including neuralgia and sensory symptoms; review of periorbital computed tomography (CT) scans; and assessment of postoperative effects of surgery for infraorbital nerve decompression...

BACKGROUND/PURPOSE: Evidence-based practice (EBP) has been identified as a foundation of mainstream medical practice, yet pediatric surgery has been slow in the acceptance and implementation of EBP. METHODS: Semi-structured interviews of 14 pediatric surgeons were conducted to determine barriers and facilitators to EBP. Resulting data were analyzed using a systematic 3-step approached of coding, generation of specific beliefs, and identification of domains relevant to practice change...

The seasonally changing photoperiod controls the timing of reproduction in most fish species, however, the transduction of this photoperiodic information to the reproductive axis is still unclear. This study explored the potential role of two candidate neuropeptide systems, gonadotropin-inhibitory hormone (Gnih) and kisspeptin, as mediators between the pineal organ (a principle transducer of photoperiodic information) and reproductive axis in male European sea bass, Dicentrarchus labrax. Two seven-day experiments of pinealectomy (Px) were performed, in March (end of reproductive season) and August (resting season)...

OBJECTIVE: The tumor microenvironment frequently displays abnormal cellular metabolism, which contributes to aggressive behavior. Metformin inhibits mitochondrial oxidative phosphorylation, altering metabolism. Though the mechanism is unclear, epidemiologic studies show an association between metformin use and improved outcomes in head and neck squamous cell carcinoma (HNSCC). We sought to determine if metformin alters metabolism and apoptosis in HNSCC tumors. STUDY DESIGN: Window of opportunity trial of metformin between diagnostic biopsy and resection...

Several studies have suggested both a local and network reorganization of the sensorimotor system following amputation. Transplantation of a new limb results in a new shifting of cortical activity in the local territory of the transplanted limb. However, there is a lack of information about the reversibility of the abnormalities at the network level. The objective of this study was to characterize the functional connectivity changes between the cortical territory of the new hand and two intrinsic network of interest: the sensorimotor network (SMN) and the default mode network (DMN) of one patient whom received bilateral forearm transplants...

Titanium (Ti) staples are not biodegradable, and anastomotic complications related to Ti staples are reported frequently. In the present study, the biocompatibility and degradation behavior of high-purity magnesium (HP Mg) staples with the small intestine were investigated. HP Mg staples did not affect the relative growth rate, cell cycle and apoptosis of primary rectal mucosal epithelial cells (IEC-6) in vitro. At one, two and three days after immersion in intestinal juice, the weight of the 30 rinsed HP Mg staples reduced by 7...

REVIEW
Andrew J Beamish, Thomas Reinehr
Adolescent obesity has markedly increased worldwide in both its extent and prevalence in recent decades and obesity prevention strategies are failing. As a result, effective treatment strategies are urgently needed. As behavioral and pharmacological treatment approaches have only moderate effects in severe obesity, bariatric surgery has begun to emerge as a treatment option. In this debate article, we offer arguments opposing and supporting bariatric surgery in the treatment of severe obesity in adolescents...

Women and girls living with female genital mutilation (FGM) are more likely to experience psychological problems than women without FGM. As well as psychological support, this population may need additional care when seeking surgical interventions to correct complications of FGM. Recent WHO guidelines recommend cognitive behavioral therapy for women and girls experiencing anxiety disorders, depression, or post-traumatic stress disorder. The guidelines also suggest that preoperative counselling for deinfibulation, and psychological support alongside surgical interventions, can help women manage the physiological and psychological changes following surgery...

BACKGROUND: Chronic pain often results in cognitive impairment. Our previous study showed that trigeminal neuralgia induced by cobra venom leads to spatial learning and memory deficits, although the underlying mechanism remains unclear. However, recent evidence indicates that the c-AMP-responsive element binding protein (CREB)/brain derived neurotrophic factor (BDNF) pathway plays a critical role in various etiologies of cognitive deficits. OBJECTIVES: Our aim was to explore the CREB/BDNF pathway to determine the molecular mechanisms involved in the pathogenesis of cognitive impairment caused by cobra venom-induced trigeminal neuralgia...

The current study evaluated the effects of Xiao Yao San (XYS) on anxiety-like behaviors and sought to determine whether the c-Jun N-terminal kinase (JNK) signaling pathway is involved. A total of 40 rats were divided into 5 groups (n=8): the control group (deionized water, per os (p.o.)), the model group (deionized water, p.o.), the SP600125 group (surgery), the per se group (surgery), and the XYS group (3.9 g/kg/d, p.o.). A 1% dimethyl sulfoxide (DMSO) citrate buffer solution (2 µL/ventricle/d) and SP600125 (10 µg/ventricle, 2 µL/ventricle/d) were separately and bilaterally injected into the rats of the two surgery groups via the ventricular system of the brain...

BACKGROUND: Alstonia scholaris commonly known as 'Saptaparni' is an Indian traditional medicinal plant used in Ayurveda. It is commonly used to treat various disorders like asthma, bronchitis, diarrhea, dysentery and malaria. In folklore medicine the milky juice of the plant is applied on wounds and ulcers to treat pain, ear ache and also in rheumatic pains. AIM: The present study was designed to investigate the potential of A. scholaris R. Br. in chronic constriction injury of sciatic nerve (CCI) induced neuropathic pain in rats...

Postoperative pain is a critical problem in clinical pain administration. Due to the unclear formation mechanism of postoperative pain, the treatment of postoperative pain is still in the symptomatic treatment stage and lacking satisfactory analgesic effect. Postoperative pain can be simulated by using a rat incision pain model. We observed changes in pain-related behavior of rats affected by the 5-hydroxytryptamine 2A receptor (5-HT2AR) agonist, TCB-2, and antagonist, ketanserin, through intrathecal delivery...

BACKGROUND: The operating theatre, anaesthesia induction and separation from parents create fear and anxiety in children. Anxiety leads to adverse behavioral changes appearing and sometimes persisting during the postoperative period. Our aim was to compare the effects of midazolam (0.3 mg kg(-)(1): MDZ) for premedication with age-appropriate tablet game apps (TAB) on children anxiety during and after ambulatory surgery. METHODS: A randomized controlled trial was conducted from May 16th, 2013 to March 25th, 2014 at the Children Hospital of Lyon...

BACKGROUND: Results from a previous multicenter randomized controlled trial (RCT) on preoperative pain neuroscience education (PNE) for lumbar radiculopathy found no significant difference in patient reported outcomes between groups. However, patients who received PNE viewed their surgical experience more favorably and utilized significantly less healthcare compared to those that did not. The purpose is to determine if the reduction in healthcare costs from 1-year would be continued at 3-year following surgery, and to explore differences (if any) in patient reported outcomes...
