#1
REVIEW
Hideki Tatewaki, Akira Shiose
In this review article, we describe pulmonary valve replacement (PVR) late after repaired Tetralogy of Fallot (TOF). Since the introduction of surgical intervention for patients with TOF in 1945, surgical management of TOF has dramatically improved early survival with mortality rates, less than 2-3%. However, the majority of these patients continue to experience residual right ventricular outflow tract pathology, most commonly pulmonary valve regurgitation (PR). The patients are generally asymptomatic during childhood and adolescence and, however, are at risk for severe PR later which can result in exercise intolerance, heart failure, arrhythmias, and sudden death...

BACKGROUND: Thoracic corpectomies are performed for various reasons including spinal deformity, trauma, neoplasms, and infection. Regardless of indication, both anterior and posterior approaches are surgical options, selected based on pathology, anatomy, patient characteristics, and surgical experience. Risk profiles and outcomes for these procedures are poorly characterized, however, and the choice between the two approaches remains inconclusive. OBJECTIVE: To compare risk factors and complications for adult patients undergoing anterior and posterior thoracic corpectomies...

OBJECTIVE: Multiple localization techniques to facilitate intraoperative identification of small or nonsolid pulmonary nodules have been developed. Radiotracer localization using technetium-labeled macroaggregated albumin has been our preferred localization method since 2009. We report our experience, including technical pitfalls and modifications, of our initial 77 patients who underwent this technique. METHODS: All patients undergoing preoperative radiotracer localization were identified from a prospective database...

Nitric oxide (NO) is a cellular signalling molecule widely conserved among organisms, including microorganisms such as bacteria, yeasts, and fungi, and higher eukaryotes such as plants and mammals. NO is mainly produced by the activities of NO synthase (NOS) or nitrite reductase (NIR). There are several NO detoxification systems, including NO dioxygenase (NOD) and S-nitrosoglutathione reductase (GSNOR). NO homeostasis, based on the balance between NO synthesis and degradation, is important for regulating its physiological functions, since an excess of NO causes nitrosative stress due to the high reactivity of NO and NO-derived compounds...

PURPOSE: The objective of the study was to describe the initial clinical and electroencephalographic findings in children with late-infantile neuronal ceroid lipofuscinosis (LINCL). METHOD: The clinical charts of 35 patients seen between 1990 and 2016 were reviewed. The patients were divided into two groups: Group 1 (G1) consisting of 12 patients with NCL type 2 (CLN2) disease confirmed by enzymatic activity in dried blood spots on filter paper and/or genetic studies, and Group 2 (G2) consisting of 23 patients with a diagnosis of LINCL based on pathology studies by muscle biopsy...

BACKGROUND: Spinal cord injury may cause cortical reconstruction. We, therefore, explored thechanges in cortical activation before and after anterior cervical decompression and fusion surgery in patients with Hirayama disease (HD). METHODS: 17 HD cases were performed anterior cervical decompression and fusion surgery. BOLD-fMRI scan was performed preoperatively, 3 months, 6 months and 1 year after surgery. Activated voxels were compared between both hands after adjusting for head motion, slice timing, spatial normalization and image smoothing...

REVIEW
Boye Dong, Zuyang Luo, Jiabao Lu, Yang Yang, Yixian Song, Jie Cao, Wanglin Li
BACKGROUND: Single-incision laparoscopic surgery has gained widespread attention because of its potential benefits such as less skin incision and faster recovery. Up to now, only one meta-analysis (performed in 2013; including 9 studies, a total of 585 cases) compared single-incision laparoscopic right colectomy (SILRC) with conventional laparoscopic right colectomy (CLRC). An updated meta-analysis was undertaken to explore more convinced comparative findings between SILRC and CLRC. MATERIALS AND METHODS: The search for studies that compared SILRC with CLRC was done on PubMed, Embase, Web of Science, and the Cochrane Library...

Pierre Robin syndrome (PRS) is characterized of a triad of clinical signs: micrognathia, glossoptosis and obstruction of the upper airways frequently associated with palatal cleft. It is a heterogenic pathological entity and it can be found as isolated disease (nsPRS) or in association with other syndromes (sPRS), with more pronounced symptoms and systemic involvement. This review aims to summarize the principal features of PRS, analysing the different aspects of the disease. Epidemiological data highlight incidence, severity and mortality of PRS; pathophysiological mechanism reports the etiology and pathogenesis of the disease distinguishing between isolated and syndromic form...

Spinocerebellar ataxia (SCA) is a neural disorder, which is caused by degenerative changes in the cerebellum. SCA is primarily characterized by gait ataxia, and additional clinical features include nystagmus, dysarthria, tremors and cerebellar atrophy. Forty-four hereditary SCAs have been identified to date, along with >35 SCA-associated genes. Despite the great diversity and distinct functionalities of the SCA-related genes, accumulating evidence supports the occurrence of a common pathophysiological event among several hereditary SCAs...

Miriam Turiel Miranda, Pau Agulles Simó
The levonorgestrel-releasing intrauterine device known as Mirena IUD(r) (20mcg/24h) is nowadays considered among the leading resources in the treatment of heavy menstrual bleeding. Nonetheless, due to either its effect of prevention of conception and especially to the possibility that it may also have an anti-implantation effect, there is a founded concern on whether its therapeutic use may be ethically licit. This article engages in an exhaustive literature review in order to ascertain the mechanism of action of Mirena(r) IUD, in view of an ethical evaluation of its therapeutic use, keeping in mind those two unwanted effects...

PURPOSE: Retrospective studies have shown that tracheotomy prior to total laryngectomy (TL) is associated with decreased survival. We sought to investigate whether this is due to higher local invasiveness associated with obstructive disease or whether it is the result of tracheotomy itself. METHODS: We reviewed patients with a T4a (AJCC 7th edition) laryngeal squamous-cell carcinoma treated with a primary TL followed by adjuvant radiotherapy between 2001 and 2013...

Anatomical variants of muscle are commonly encountered by surgeons and radiologists. The flexor carpi radialis brevis (FCRB) is an anomalous muscle in the distal forearm with an estimated prevalence of 2-8%. In the literature, there are a few case reports of symptomatic FCRB tenosynovitis without a concomitant tear, and treatment methods described include both conservative and surgical management. We present a case of one patient with radial sided wrist pain and a partial FCRB tear, which to our knowledge is the first case report of a symptomatic FCRB tear...

Alzheimer's disease (AD) is a neurodegenerative condition characterized by progressive cognitive decline and memory loss, and is the most common form of dementia. Amyloid plaques with neurofibrillary tangles are a neuropathological hallmark of AD that produces synaptic dysfunction and culminates later in neuronal loss. Amyloid PET is a useful, available and non-invasive technique that provides in vivo information about the cortical amyloid burden. In the latest revised criteria for the diagnosis of AD biomarkers were defined and integrated: pathological and diagnostic biomarkers (increased retention on fibrillar amyloid PET or decreased Aβ1-42 and increased T-Tau or P-Tau in CSF) and neurodegeneration or topographical biomarkers (temporoparietal hypometabolism on 18 F-FDG PET and temporal atrophy on MRI)...

REVIEW

Damaged cells at risk of neoplastic transformation can be neutralized by apoptosis or engagement of the senescence program, which induces permanent cell-cycle arrest and a bioactive secretome that is implicated in tumor immunosurveillance. While from an evolutionary perspective senescence is beneficial in that it protects against malignancies, the accumulation of senescent cells in tissues and organs with aging and at sites of various pathologies is largely detrimental. Because induction of senescence in cancer cells is emerging as a therapeutic concept, it will be important to consider these detrimental effects, including tumor-promoting properties that may drive the formation of secondary tumors or cancer relapse...

Receptor tyrosine kinases (RTKs) such as the insulin-like growth factor type 1 receptor (IGF-1R) control important biological activities as well as being involved in pathological processes. Due to their supportive nature in many human cancers they have long been considered attractive therapeutic targets. However, lessons learnt from early targeting trials highlight that a simple "active versus inactive" state model with classical kinase-only signaling is overly simplistic and does not describe reality...

Multiple myeloma is the second most frequent hematological malignancy in the western world and remains incurable, predominantly due to acquired drug resistance and disease relapse. The highly conserved Wnt signal transduction pathway, which plays a key role in regulating cellular processes of proliferation, differentiation, migration, and stem cell self-renewal, is associated with multiple aspects of disease. Bone homeostasis is severely disturbed by Wnt antagonists that are secreted by the malignant plasma cells in the bone marrow...

REVIEW
Ana-Maria Negulescu, Patrick Mehlen
Transmembrane receptors are usually seen as on and off switch: when the specific ligand is bound, the receptor is on and transduces a downstream signal, while when the ligand is absent, the receptor is off. Over the last two decades several reports have argued from an alternative view where some receptors, depending on the context, will be active both in the presence and in the absence of ligand, being sort of onA and onB switch rather than on and off. These receptors have been named Dependence Receptors (DR) and they share the ability to actively trigger cell death when unbound by their respective ligands...

BACKGROUND:  Microvascular reconstruction of the anterior cranial fossa (ACF) creates difficult challenges. Reconstructive goals and flap selection vary based on the defect location within the ACF. This study evaluates the feasibility and reliability of free tissue transfer for salvage reconstruction of low, middle, and high ACF defects. METHODS:  A retrospective review was performed. Reconstructions were anatomically classified as low (anterior skull base), middle (frontal bar/sinus), and high (frontal bone/soft tissue)...
