Primary Cutaneous Follicular Helper T-Cell Lymphoma: A Case Series and Review of the Literature
Authors: Wang James Y. , Nguyen Giang Huong , Ruan Jia , Magro Cynthia M. 
Published: April 2017

Abstract:Primary cutaneous follicular helper T-cell (Tfh) lymphoma is a recently described variant of peripheral T-cell lymphoma—not otherwise specified. This particular variant, usually presenting as a sudden onset of multiple plaques and nodules, is characterized by tumoral atypical T cells that express an array of Tfh markers, such as inducible T-cell costimulator, Bcl-6, CXCL13, PD-1, and CD10. The authors now present 3 patients whose known clinical skin findings are consistent with PTCL of Tfh origin (PTCL-Tfh). The typically protracted pattern of skin disease manifesting as scaly patches and plaques encountered in mycosis fungoides was not seen in our 3 cases, and there were distinguishing light microscopic and phenotypic features. These cases are similar to the few previous reported cases of PTCL-Tfh, although systemic involvement was not seen. The categorization of additional patients into this PTCL subtype in the medical literature would be needed to further characterize this new entity and may lead to better targeted treatments based on specific T-cell subtypes.
IncobotulinumtoxinA for Aesthetic Indications: A Systematic Review of Prospective Comparative Trials
Authors: Prager Welf , Nogueira Teixeira Diana , Leventhal Phillip S. 
Published: April 2017

BACKGROUND
IncobotulinumtoxinA is a botulinum toxin type A (BoNTA) indicated for temporary improvement in the appearance of upper facial lines with well-established efficacy and safety profiles. Whether incobotulinumtoxinA and other BoNTAs are equipotent is subject of debate.

OBJECTIVE
To compare the efficacy of incobotulinumtoxinA and other BoNTAs for aesthetic applications.

MATERIALS AND METHODS
PubMed and Embase were systematically searched for prospective clinical trials comparing incobotulinumtoxinA with onabotulinumtoxinA, abobotulinumtoxinA, or placebo for aesthetic applications.

RESULTS
Fifteen articles met the selection criteria. Two studies found that incobotulinumtoxinA was noninferior or equivalent to onabotulinumtoxinA for the treatment of glabellar frown lines (GFLs). Eight studies found no difference in efficacy between incobotulinumtoxinA and other BoNTAs. One study suggested differences in response rates at certain time points between incobotulinumtoxinA and onabotulinumtoxinA for GFLs, and one suggested differences for dynamic horizontal forehead lines but not for GFLs or lateral periorbital lines, but both had study design issues limiting the ability to draw conclusions. Finally, 3 placebo-controlled studies demonstrated the efficacy of incobotulinumtoxinA for treating GFLs and upper facial lines.

CONCLUSION
The weight of the evidence from comparative clinical trials indicates that incobotulinumtoxinA, onabotulinumtoxinA, and abobotulinumtoxinA have similar efficacy for aesthetic applications.
Safety of Cochlear Implants in Electrosurgery: A Systematic Review of the Literature
Authors: Behan James , Higgins Shauna , Wysong Ashley 
Published: April 2017

BACKGROUND
The implications of electrosurgical instrument use in patients with cochlear implants (CIs) are becoming increasingly relevant for dermatologic surgeons as the number of implanted CI devices continues to grow. The literature, however, fails to provide clear recommendations for appropriate treatment of these patients.

OBJECTIVE
To systematically consolidate and critique the current literature regarding electrosurgical instrument use in patients with CI, to determine implications of various electrosurgical devices and settings on CI function and health of cochlear tissues, and to devise recommendations for appropriate use.

MATERIALS AND METHODS
The manuscript was created based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. A broad search of PubMed, Access Medicine, Clinical Key, Ovid, Scopus, the Cochrane Library, and Web of Science was performed using key words such as CI, electrosurgery, and/or electrosurgical device. Criteria for inclusion included being written in English language and institutional access to manuscript. All years were included. Additional references were obtained from personal communication with CI manufacturers. Study biases were assessed through evaluation of funding and/or sponsoring agencies for included studies.

RESULTS
The authors' search yielded a total of 8 studies, 5 of which were a level of evidence 5, 2 of which were level of evidence 4, and 1 of which was a level of evidence 3. The remaining study was relegated only to device testing. These studies were complicated by inaccurate terminology and inconsistent recommendations.

CONCLUSION
The body of evidence evaluating electrosurgical instrument use in patients with CI is severely limited in number and quality. Thus, vague and inconsistent recommendations have emerged that place patients at risk of serious and costly adverse effects. In light of this, the authors suggest use of the most conservative recommendations available for electrosurgical instrument use in patients with CI.
Advancing Keloid Treatment: A Novel Multimodal Approach to Ear Keloids
Authors: Jones Michael E. , McLane Jennifer , Adenegan Rachael , Lee JoAnne , Ganzer Christine A. 
Published: April 2017

BACKGROUND/OBJECTIVE
Management of keloids of the pinna, in particular, those located in the helix and antihelix and lobule that occur as complications of ear piercing.

MATERIALS AND METHODS
Retrospective analysis of 49 patients treated with extralesional surgical excision of keloids localized to the ear followed by the application of autologous platelet-rich plasma (PRP) to wound site and postoperative in-office superficial radiation therapy (SRT). Radiation protocol consisted of 1 to 3 fractions, with cumulative dosage ranging from 1,300 to 1,800 cGy. Average follow-up was 24 months to assess for evidence of recurrence and adverse side effects.

RESULTS
Fifty ear keloids were treated with this method, age from 15 to 66 (mean = 32, SD = 16) of which 14 were male and 35 female. Almost 30% (n = 14) of patients acknowledged the source of injury that led to the development of the keloid was ear piercing. Treatment protocol achieved a 94% success rate with 3 patients who reported recurrence.

CONCLUSION
Surgical excision combined with intraoperative PRP, adjuvant postoperative in-office SRT achieved a 94% nonrecurrence rate on follow-up over a 2-year period. Outcomes provide preliminary, albeit, strong evidence to support this multimodal method as a viable alternative in the management of keloids localized to the ear.
Elongated Dorsal Nasal Flap to Reconstruct Large Defects of the Nose
Authors: Redondo Pedro , Bernad Isabel , Moreno Ester , Ivars Marta 
Published: April 2017

BACKGROUND
The typical reconstructive option for closing large-sized defects of the distal half of the nose is the paramedian forehead flap. Other alternatives are a melolabial interpolation flap and bilobed or trilobed flaps. The dorsal nasal (Rieger) flap is suitable for closing small-sized defects at this location, especially when they are medially located.

OBJECTIVE
The authors describe a modified dorsal nasal flap reconstruction for large nasal defects. The novelty of this study lies in lengthening the leading edge of flap rotation, which may provide tissue either from the adjacent nasal skin, the nasofacial groove, or the cheek.

MATERIALS AND METHODS
The authors performed a retrospective chart review of all patients with large defects (>20 mm) of the nose who underwent modified dorsal nasal flap repair between January 2004 and March 2015 at a single academic center.

RESULTS
Twenty-seven patients (16 male, 11 female; ages 44–88, mean age 62 years) had defects (the smallest 15 × 21 mm, and the largest 32 × 37 mm) on the lower portion of the nasal pyramid. Follow-up ranged from 12 months to 11 years with good or excellent results in all cases.

CONCLUSION
Elongated dorsal nasal flap is a reproducible one-stage flap for large defects of the nose, with minimal risk of aesthetic or functional complications.
Combined Treatment With Exenatide and Cyclosporine A or Parstatin 1-26 Results in Enhanced Reduction of Infarct Size in a Rabbit Model
Authors: Alexopoulos Panagiotis , Panoutsopoulou Konstantina , Vogiatzis George , Koletsis Efstratios , Dougenis Dimitrios , Tsopanoglou Nikos E. 
Published: April 2017

Abstract:
Exenatide and cyclosporine A have been shown to moderately protect against myocardial reperfusion injury leading to reduction of infarct size in patients. Our objective was to investigate whether the combined treatment with exenatide (glucagon-like peptide 1 receptor agonist) and cyclosporine A or parstatin 1-26 (inhibitors of mitochondrial permeability transition pore and/or inflammation) is more beneficial than either agent alone. Rabbits underwent 40 minutes of ischemia and 120 minutes of reperfusion. Intravenous bolus administration of exenatide or cyclosporine A, 10 minutes before reperfusion, reduced infarct size by 38% (P < 0.05) and 40% (P < 0.05), and cardiac troponin I (cTnI) plasma levels by 48% (P < 0.05) and 36% (P < 0.05), respectively, compared with control. The combined administration of both agents resulted in an additive decrease of infarct size by 55% (P < 0.05) and cTnI release by 61% (P < 0.05). Also, combined treatment of exenatide and parstatin 1-26 enhanced infarct size reduction (62%, P < 0.05), compared with monotherapies (41% for parstatin 1-26, P < 0.05; 43% for exenatide, P < 0.05). In contrast, the combined administration of parstatin 1-26 and cyclosporine A canceled out the cardioprotective effects observed by monotherapies. These results suggest that, for the therapy of myocardial reperfusion injury the combined administration of exenatide and cyclosporine A or parstatin 1-26 is more effective than monotherapies and may provide advantageous clinical outcome.

Authors: Harthan Jennifer , Nau Cherie B. , Barr Joseph , Nau Amy , Shorter Ellen , Chimato Nicolette T. , Hodge David O. , Schornack Muriel M. 
Published: April 2017

Objectives:
To assess current scleral lens prescription and management practices by conducting an international online survey of eye care providers.

Methods:
The SCOPE (Scleral Lenses in Current Ophthalmic Practice: an Evaluation) study group designed and administered an online survey regarding current scleral lens prescription and management practices. The survey was open from January 15 to March 31, 2015, and generated 723 responses from individuals who had fit at least 5 patients with scleral lenses.

Results:
Respondents (n=663) prescribed scleral lenses that ranged from 15 to 17 mm in diameter (65%), smaller than 15 mm (18%), and larger than 18 mm (17%). More than 50 lens designs were identified. Average daily wearing time of 11.8 hr was consistent across 651 respondents, and 475/651 (73%) recommended midday removal on some, most, or all days. Most respondents recommended nonpreserved saline to fill the bowl of the lens before application (single-use vials, 392/653 [60%]; bottled products, 372/653 [57%]). A hydrogen peroxide-based disinfection system was the most commonly recommended care product (397/651 [61%]).

Conclusions:
A reasonable degree of consensus exists regarding some aspects of scleral lens prescription and management (average lens diameter, daily wearing time, and use of nonpreserved products for lens application). Further study is needed to develop evidence-based guidelines for scleral lens prescription and management.
Glaucoma Drainage Device Erosion Following Ptosis Surgery
Authors: Bae Steven S. , Campbell Robert J. 
Published: April 2017

Purpose:
To highlight the potential risk of glaucoma drainage device erosion following ptosis surgery.

Methods:
Case report.

Results:
A 71-year-old man underwent uncomplicated superotemporal Ahmed glaucoma valve implantation in the left eye in 2008. Approximately 8 years later, the patient underwent bilateral ptosis repair, which successfully raised the upper eyelid position. Three months postoperatively, the patient’s glaucoma drainage implant tube eroded through the corneal graft tissue and overlying conjunctiva to become exposed. A graft revision surgery was successfully performed with no further complications.

Conclusions:
Caution and conservative lid elevation may be warranted when performing ptosis repair in patients with a glaucoma drainage implant, and patients with a glaucoma implant undergoing ptosis surgery should be followed closely for signs of tube erosion.
Targeting brain-derived neurotrophic factor in the medial thalamus for the treatment of central poststroke pain in a rodent model
Authors: Shih Hsi-Chien , Kuan Yung-Hui , Shyu Bai-Chung 
Published: April 2017

Abstract
Approximately 7% to 10% of patients develop a chronic pain syndrome after stroke. This chronic pain condition is called central poststroke pain (CPSP). Recent studies have observed an abnormal increase in the secretion of brain-derived neurotrophic factor (BDNF) in spinal cord tissue after spinal cord injury. An animal model of CPSP was established by an intrathalamus injection of collagenase. Mechanical and thermal allodynia was induced after lesions of the thalamic ventral basal complex in rats. Four weeks after the injection, the number of neurons decreased, the number of astrocytes, microglia, and P2X4 receptors increased, and BDNF mRNA expression increased in the brain lesion area. Nociceptive activity in the medial thalamus (MT) and the coherence coefficient of spontaneous field potential oscillations in the anterior cingulate cortex were enhanced in CPSP animals, and these enhancements were blocked by an acute injection of TrkB-Fc and TrkB antagonist Tat Cyclotraxin-B. Instead of being inhibited by the γ-aminobutyric acid (GABA) system in normal rats, multiunit activity in the MT was enhanced after a microinjection of muscimol, a GABAA receptor agonist, in CPSP animals. After CPSP, BDNF expression was enhanced in the MT, whereas the expression of GABAA channels and the cotransporter KCC2 decreased in the same area. These findings suggest that neuronal plasticity in the MT that was induced by BDNF overexpression after the thalamic lesion was a key factor in CPSP.
The postoperative Model for End stage Liver Disease score as a predictor of short-term outcome after transplantation of extended criteria donor livers
Authors: Benko Tamas , Gallinat Anja , Minor Thomas , Saner Fuat H. , Sotiropoulos Georgios C. , Paul Andreas , Hoyer Dieter P. 
Published: April 2017

Background
Recently, the postoperative Model for End stage Liver Disease score (POPMELD) was suggested as a definition of postoperative graft dysfunction and a predictor of outcome after liver transplantation (LT).

Aim
The aim of the present study was to validate this concept in the context of extended criteria donor (ECD) organs.

Patients and methods
Single-center prospectively collected data (OPAL study/01/11-12/13) of 116 ECD LTs were utilized. For each recipient, the Model for End stage Liver Disease (MELD) score was calculated for 7 postoperative days (PODs). The ability of international normalized ratio, bilirubin, aspartate aminotransferase, Donor Risk Index, a recent definition of early allograft dysfunction, and the POPMELD was compared to predict 90-day graft loss. Predictive abilities were compared by receiver operating characteristic curves, sensitivity and specificity, and positive and negative predictive values.

Results
The median Donor Risk Index was 1.8. In all, 60.3% of recipients were men [median age of 54 (23–68) years]. The median POD1–7 peak-aspartate aminotransferase value was 1052 (194–17 577) U/l. The rate of early allograft dysfunction was 22.4%. The 90-day graft survival was 89.7%. Out of possible predictors of the 90-day graft loss MELD on POD5 was the best predictor of outcome (area under the curve=0.84). A MELD score of 16 or more on POD5 predicted the 90-day graft loss with a specificity of 80.8%, a sensitivity of 81.8%, and a positive and negative predictive value of 31 and 97.7%.

Conclusion
A MELD score of 16 or more on POD5 is an excellent predictor of outcome in ECD donor LT. Routine evaluation of POPMELD scores might support clinical decision-making and should be reported routinely in clinical trials.
Risks and Benefits of Swaddling Healthy Infants
Authors: Nelson Antonia M. 
Published: April 2017

Abstract

Background:
Swaddling has been practiced since antiquity; however, there is controversy about its safety.

Objectives:
The purpose of this review is to update and build upon previous reviews and synthesize evidence on risks and benefits of swaddling in healthy-term, near-term, or older infants.

Data Sources:
MEDLINE (1960–May 13, 2016) and CINAHL (1963–May 13, 2016) searches were conducted, relevant articles retrieved, and citation lists reviewed for other references.

Synthesis Methods:
A table summarizes study details. Selected older references and supporting literature are integrated into the synthesis to provide context.

Results:
Swaddling calms infants and promotes sleep, but it is equally or less effective than other nonpharmacological methods in managing pain. There may be a slight risk for sudden infant death syndrome associated with supine swaddling, although the impact of confounding variables is unclear. Early skin-to-skin contact supports early breastfeeding, but swaddling does not have a negative impact on breastfeeding long term. Swaddling tightly around the hips is strongly associated with developmental dysplasia of the hip. More research is needed on the impact of swaddling on pain in term infants, infant vital signs, arousal thresholds, and a possible association between swaddling, vitamin D deficiency, and acute lower respiratory tract infection.

Limitations:
The number of studies was small, with few randomized control trials, and researchers used different definitions of swaddling.

Conclusions:
If a few precautions are taken, such as swaddling securely to minimize risk of unwrapping, avoiding overheating, placing infants to sleep supine, and discontinuing swaddling when infants first show signs of rolling over, swaddling presents minimal risk.

Clinical Implications:
Maternity and neonatal nurses should model swaddling practices based on the evidence and promote informed decision-making among infant caregivers.
Formin-Dependent Adhesions are Required for Invasion by Epithelial Tissues
Authors: Fessenden Tim B. , Beckham Yvonne , Perez-Neut Mathew , Chourasia Aparajita H. , Macleod Kay F. , Oakes Patrick W. , Gardel Margaret L. 
Published: April 2017

AbstractDeveloping tissues change shape, and tumors initiate spreading, through collective cell motility. Conserved mechanisms by which tissues initiate motility into their surroundings are not known. We investigated cytoskeletal regulators during collective invasion by mouse tumor organoids and epithelial MDCK acini undergoing branching morphogenesis. Inhibition of formins, but not Arp2/3, prevented the formation of migrating cell fronts in both cell types. MDCK cells depleted of the formin protein Dia1 formed polarized acini and could execute planar cell motility, either within the acinus or in 2D scattering assays. However, Dia1 was required to form protrusions into the collagen matrix. Live imaging of actin, myosin, and collagen in control acini revealed adhesions that deformed individual collagen fibrils, while Dia1-depleted acini exhibited unstable adhesions with minimal collagen deformation. This work identifies Dia1-mediated adhesions as essential regulators of tissue shape changes, through their role in focal adhesion maturation.

AbstractCancer drug screening in patient-derived cells holds great promise for personalized oncology and drug discovery but lacks standardization. Whether cells are cultured as conventional monolayer or advanced organoid cultures influences drug effects and thereby drug selection and clinical success. To precisely compare drug profiles in differently cultured primary cells, we developedDeathPro, an automated microscopy-based assay to resolve drug-induced cell death and proliferation inhibition. UsingDeathPro, we screened cells from ovarian cancer patients in monolayer or organoid culture with clinically relevant drugs. Drug-induced growth arrest and efficacy of cytostatic drugs differed between the two culture systems. Interestingly, drug effects in organoids were more diverse and had lower therapeutic potential. Genomic analysis revealed novel links between drug sensitivity and DNA repair deficiency in organoids that were undetectable in monolayers. Thus, our results highlight the dependency of cytostatic drugs and pharmacogenomic associations on culture systems, and guide culture selection for drug tests.
Disruption of perineuronal nets increases the frequency of sharp wave ripples

Published: April 2017

AbstractHippocampal sharp wave ripples (SWRs) represent irregularly occurring synchronous neuronal population events that are observed during phases of rest and slow wave sleep. SWR activity that follows learning involves sequential replay of training-associated neuronal assemblies and is critical for systems level memory consolidation. SWRs are initiated by CA2 or CA3 pyramidal cells and require initial excitation of CA1 pyramidal cells as well as subsequent participation of parvalbumin (PV) expressing fast spiking (FS) inhibitory interneurons. These interneurons are relatively unique in that they represent the major neuronal cell type known to be surrounded by perineuronal nets (PNNs), lattice like structures composed of a hyaluronin backbone that surround the cell soma and proximal dendrites. Though the function of the PNN is not completely understood, previous studies suggest it may serve to localize glutamatergic input to synaptic contacts and thus influence the activity of ensheathed cells. Noting that FS PV interneurons impact the activity of pyramidal cells thought to initiate SWRs, and that their activity is critical to ripple expression, we examine the effects of PNN integrity on SWR activity in the hippocampus. Extracellular recordings from the stratum radiatum of 490 micron horizontal murine hippocampal hemisections demonstrate SWRs that occur spontaneously in CA1. As compared to vehicle, pretreatment (120 min) of paired hemislices with hyaluronidase, which cleaves the hyaluronin backbone of the PNN, decreases PNN integrity and increases SWR frequency. Pretreatment with chondroitinase, which cleaves PNN side chains, also increases SWR frequency. Together, these data contribute to an emerging appreciation of extracellular matrix as a regulator of neuronal plasticity and suggest that one function of mature perineuronal nets could be to modulate the frequency of SWR events.
