Usefulness of dermoscopy/dermatoscopy to improve the clinical and histopathologic diagnosis of skin cancers

Multiple studies have shown that dermoscopy increases the sensitivity and specificity for the detection of skin cancers compared to naked-eye examination. Dermoscopy can also lead to the detection of thinner and smaller cancers. Furthermore, dermoscopy leads to more precise selection of lesions requiring excision. In essence, dermoscopy helps clinicians differentiate benign from malignant lesions through the presence or absence of specific dermoscopic structures. Therefore, since most dermoscopic structures have direct histopathologic correlates, dermoscopy can allow the prediction of certain histologic findings present in skin cancers, thus helping select management and treatment options for select types of skin cancers.

Dermoscopy/dermatoscopy and dermatopathology correlates of cutaneous neoplasms

Dermoscopy is increasingly used by clinicians (dermatologists, family physicians, podiatrists, doctors of osteopathic medicine, etc.) to inform clinical management decisions. Dermoscopic findings and/or images provided to pathologists offer an important insight into the clinician's diagnostic and management thought process. However, with limited dermoscopic training in dermatopathology, dermoscopic descriptions and images provided in the requisition form will provide little value to pathologists.

Orbital decompression in thyroid eye disease

Thyroid eye disease is an orbital inflammatory manifestation of autoimmune thyroid disease that results in orbital congestion and can lead to significant cosmetic disfigurement, diplopia, and vision loss. Typically, there is an active, inflammatory phase that transitions into a quiescent, fibrotic state. Management of this condition consists of regulation of the underlying thyroid disease, modulation of risk factors, supportive care for symptoms, and both medical and surgical treatment of ocular sequelae.

Indication and Technique of Orbital Exenteration

Orbital exenteration is a rare, severely disfiguring operation for the treatment of malignant orbital tumors. The tumors can arise from the orbit, metastasize to the orbit from distant sites, or invade the orbit from surrounding structures. The technique of exenteration mandates complete removal of the intraorbital contents, sometimes including the encompassing bony structures. This article will describe the indications and technique of orbital exenteration, as well as complications and several reconstructive strategies.

Imaging of the Human Orbit

Imaging of the human orbit has significantly improved the diagnosis and management of orbital conditions. Prior to the use of CT and MRI imaging, the value of plain radiographs of the orbit was very limited. Today, modern imaging techniques are an essential adjunct to the physical examination of the eye and orbit, can confidently limit the differential, and in many cases yield a specific diagnosis. In addition, the value of imaging cannot be understated in surgical planning for orbital conditions.

Anatomy of the Human Orbit

The contents of the human orbit develop from all embryonic germinal layers to form diverse and specialized interconnected structures, whose unified function is that of providing sight. A thorough knowledge of these structures and their inter-relationships is imperative for the head and neck surgeon. This article will discuss the structures contained within the orbit from a surgical perspective in the hope of expanding the head and neck surgeon's knowledge and comfort when treatment indication necessitates entry into this space.

Mutations in PERP cause dominant and recessive keratoderma

Investigation of genetic determinants of Mendelian skin disorders has substantially advanced understanding of epidermal biology. Here we show that mutations in PERP, encoding a crucial component of desmosomes, cause both dominant and recessive human keratoderma. Heterozygosity for a C-terminal truncation, which produces protein that appears to be unstably incorporated into desmosomes, causes Olmsted syndrome with severe periorificial and palmoplantar keratoderma in multiple unrelated kindreds. Homozygosity for an N-terminal truncation ablates expression and causes widespread erythrokeratoderma, with expansion of epidermal differentiation markers.

Background

Adipose tissue has classically functioned as a filler in restoring facial volume. Adipose tissue is also rich in stem cells, which may have a role in regenerative medicine.

Objective

To summarize the literature on the clinical uses of adipose tissue in scarring, wound healing, and hair growth and determine whether evidence exists for changes in clinical practice in dermatology.

Methods

We utilized the Preferred Reporting Items for Systemic Reviews and Meta-Analyses to conduct the review. The PubMed search engine was used to assess the available literature on adipose tissue in scarring, wound healing, and hair growth.

Results

A total of 13 studies matched our inclusion criteria; 6 of the 7 studies on scar treatment, all 3 studies on wound healing, and all 3 studies on hair growth demonstrated improved outcomes with adipose tissue treatments.

Limitations

The literature supporting the use of adipose tissue is limited to case series, cohort studies, and small randomized controlled trials, which have an overall low level of evidence.

Conclusion

The existing evidence for adipose tissue as a treatment option in scarring, wound healing, and hair growth is not strong enough to justify changes to current clinical practice. The literature does provide evidence for future large randomized clinical trials.



Stratégie de prise en charge initiale des brûlures de la face : à propos de 3 cas

Résumé
Introduction

La prise en charge des brûlures de la face au stade aigu conditionne la plupart des séquelles à venir. Un traitement initial de bonne qualité doit permettre de réduire voire d'éviter la rançon cicatricielle, et ne pas compromettre la réparation ultérieure éventuelle. Il s'appuie sur le respect des règles de base de la chirurgie faciale et sur l'utilisation de quelques points techniques particuliers.

Case reports

Nous avons illustré notre protocole chirurgical par le biais de trois cas cliniques. L'excision chirurgicale des lésions non cicatrisées est réalisée entre le douzième et quinzième jour post-brûlure, suivie dans le même temps opératoire d'une couverture par greffe de peau dermo-épidermique. Cette greffe doit être prélevée au niveau du cuir chevelu chaque fois que cela est possible. Les jonctions entre unités esthétiques sont impérativement respectées. Les lambeaux peuvent s'avérer nécessaires à ce stade de la prise en charge.

Discussion et conclusion

Les résultats cosmétiques et fonctionnels observés à long terme chez les patients victimes de brûlures de la face montrent une grande diversité en fonction du traitement initial. Des patients gravement brûlés correctement pris en charge initialement peuvent ainsi présenter un meilleur résultat que des patients brûlés moins sévèrement mais mal traités.

Summary
Introduction

The management of facial burns in their acute stage determines most of the sequelae aspect. An initial treatment of good quality should reduce and even prevent scar ransom and should not compromise potential future corrections. This treatment is based on the respect of facial surgery standards and on the use of some particular technical points.

Case reports

We described our surgical protocol through three case reports. We are performing a surgical excision of the unhealed lesions between the 12th and 15th postburn day. This excision is followed by a dermoepidermal skin graft in the same operative time. This graft must be harvested from the scalp every time it is possible and must be manually perforated. All the aesthetic units junctions are necessarily respected. Flaps can be necessary at this stage.

Discussion and conclusion

The long-term functional and cosmetic results observed in patients with facial burns vary a lot depending on the initial treatment. Patients with severe burns that benefited from an appropriate initial treatment may thus present better results than patients with less severe burns who were badly treated.



Development of Quantitative Estimates of Wood Dust Exposure in a Canadian General Population Job-Exposure Matrix Based on Past Expert Assessments

Abstract
Objectives
The CANJEM general population job-exposure matrix summarizes expert evaluations of 31 673 jobs from four population-based case–control studies of cancer conducted in Montreal, Canada. Intensity in each CANJEM cell is represented as relative distributions of the ordinal (low, medium, high) ratings of jobs assigned by the experts. We aimed to apply quantitative concentrations to CANJEM cells using Canadian historical measurements from the Canadian Workplace Exposure Database (CWED), taking exposure to wood dust as an example.
Methods
We selected 5170 personal and area wood dust measurements from 31 occupations (2011 Canadian National Occupational Classification) with a non-zero exposure probability in CANJEM between 1930 and 2005. The measurements were taken between 1981 and 2003 (median 1989). A Bayesian hierarchical model was applied to the wood dust concentrations with occupations as random effects, and sampling duration, year, sample type (area or personal), province, and the relative proportion of jobs exposed at medium and high intensity in CANJEM cells as fixed effects.
Results
The estimated geometric mean (GM) concentrations for a CANJEM cell with all jobs exposed at medium or high intensity were respectively 1.3 and 2.4 times higher relative to a cell with all jobs at low intensity. An overall trend of −3%/year in exposure was observed. Applying the model estimates to all 198 cells in CANJEM with some exposure assigned by the experts, the predicted 8-hour, personal wood dust GM concentrations by occupation for 1989 ranged from 0.48 to 1.96 mg m−3.
Conclusions
The model provided estimates of wood dust concentrations for any CANJEM cell with exposure, applicable for quantitative risk assessment at the population level. This framework can be implemented for other agents represented in both CANJEM and CWED.

Abstract

A new class of triazine ligands (E)-2-(2-(6–methyl-5-oxo-2,5-dihydro-1,2,4-triazin-3-yl)hydrazono)propanoic acid hydrate (HL1.H2O) and (Z)-2-(((E)-4-amino-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazin-3(2H)ylidene)hydrazono)propanoic acid (H2L2) has been synthesized by the condensation reaction of pyruvic acid with diaminoguanidine and triaminoguanidine respectively. The corresponding Schiff base cobalt complexes [Co(L1)2].2H2O (1) and [Co(HL2)(L2)].H2O (2) have also been synthesized and characterized by analytical, thermal, spectroscopic and diffraction studies. Strong field ligand results low spin Co(III) centre in 2, which was evidenced by the shorter bond length of Co(III) complex. In H2L2 there is a choice of coordination modes based on distinct sets of donor atoms, both of which are seen in complex 2, involving either an –NH2 group on position 4 of the triazine ring, or via a ring nitrogen of the triazine itself. The deprotonation of one version of L2 allows the formation of the ligand field stabilized low spin Co(III) in 2. In complex 1, each ligand binds to the metal via pyruvate oxygen, azomethine nitrogen and triazine nitrogen forming two five-membered stable chelate rings. In complex 2, the coordination sphere assembled by two types of coordinating atoms from the same ligand with different conformation. Their binding ability and mode of binding with CT-DNA and BSA was studied by UV- absorption, fluorescence and CD spectroscopy. Density Functional Theory (DFT) studies provide further insights into the mode of binding, structure and mechanism. The HOMO and LUMO energy gap values indicate that both the complexes are prone to interact with CT-DNA and BSA. We have also performed molecular docking calculations to understand the mode of binding and the corresponding results confirm our experimental findings.

Abstract

Wound healing is an essential process in which the separated or destroyed tissue attempts to restore itself into its normal state. In some instances, healing is prolonged and remains stagnant in the inflammatory phase, and is referred to as a chronic wound. At a cellular and molecular level, many factors are required during the process of successful wound healing, such as cytokines, polypeptide growth factors and components of the extracellular matrix (ECM). Transforming growth factor-beta (TGF-β) is considered as one of the essential growth factors in wound healing. Working through the Smad pathway, it is the main inducer of fibroblast differentiation which is essential for wound healing. Photobiomodulation (PBM) shows significant advantages in wound healing, and may stimulate cellular processes and tissue regeneration that results in an increase in growth factors and a decrease in inflammatory cytokines. Moreover, it leads to enhanced cell proliferation, migration, angiogenesis, and increased adenosine triphosphate (ATP) and cytochrome C oxidase (CCO) activity. In this review paper, we discuss the effects of PBM and its role on the activation of the TGF-β/Smad pathway in the process of wound healing.

Complicity and the responsibility dilemma

Abstract

Jeff McMahan famously defends a moral inequality of combatants, where liability to be attacked and potentially killed in war, should be grounded in the individual combatant's moral responsibility for posing an unjust threat. In a response, Seth Lazar shows that McMahan's criterion for liability leads to an unacceptable dilemma between "contingent pacifism" and "total war", i.e. between war being practically infeasible, or implausibly many civilians being legitimate targets. The problem is that McMahan grounds liability mainly in the individual's causal responsibility for posing an unjust threat, but where a large proportion of combatants and civilians are approximately equally causally responsible. Recently, Saba Bazargan has come to the aid of McMahan by injecting an alternative supplementary criterion for liability, namely the individual's complicity in a group act. This criterion is supposed to uphold the noted moral inequality, while avoiding the responsibility dilemma, by grounding moral incrimination in the individual's participatory intention, instead of her causal contribution. I argue that the complicity account fails to resolve the dilemma. It fails because complicity grounded in a causally inert participatory intention is insufficient for liability. Further, I show why this reveals a deeper problem with the complicity account itself, namely that though it purports to ground incrimination non-causally, it fails to do so to any serious extent.



Glioblastoma survival is improving despite increasing incidence rates: a nationwide study between 2000 and 2013 in Finland

Abstract
Background
We assessed population-level changes in glioblastoma survival between 2000 and 2013 in Finland, with focus on elderly patients (>70 years) in order to assess if changes in treatment of glioblastoma are reflected also in population-based survival rates.
Methods
We identified all patients (age ≥18 years) from the Finnish Cancer Registry (FCR) with a histopathological diagnosis of primary glioblastoma in 2000–2013. Patients were followed up until December 2015. The accuracy of register-based search of glioblastoma patients was internally validated. We report age-standardized relative survival ratios and relative excess risks of death (RER) between 2000–2006 (pre) and 2007–2013 (post-period).
Results
We identified 2,045 glioblastoma patients from the FCR. The accuracy of the FCR-based search was 97%. Median age was 63.3 years, and 42% were women. Incidence increased on average by 1.6% (p=0.004) and median age by 0.4 years per calendar year. Between the pre and post-period, the proportion of patients >70 years increased from 24% to 27%. In >70-year-old patients, the median survival time increased from 3.6 months in 2000–2006 to 4.5 months in 2007–2013 (RER 0.82, 95% CI 0.68–0.98). In ≤70-year-old-patients, the median survival time increased from 9.3 months in 2000–2006 to 11.7 months in 2007–2013 (RER 0.74, 95% CI 0.67–0.82).
Conclusion
Despite the increased proportion of elderly glioblastoma patients, population-level survival of glioblastoma patients have improved since year 2000. However, increasing incidence, increasing age of patients, and poor survival in elderly are alarming, and future studies should perhaps focus more on elderly.
