Abstract

Background
Scarce evidence associates the first-year estimated glomerular filtration rate (eGFR) variability and longitudinal change scales concomitantly to the risk of developing end-stage renal disease (ESRD), acute coronary syndrome (ACS) and death following pre-ESRD program enrollment in chronic kidney disease (CKD).

Methods
We conducted a prospective cohort study of 5092 CKD patients receiving multidisciplinary care between 2003 and 2015 with careful ascertainment of ESRD, ACS and death during the follow-up. First-year eGFR variability and longitudinal change scales that were based on all first-year eGFR measurements included coefficient of variation of eGFR (eGFR-CV), percent change (eGFR-PC), absolute difference (eGFR-AD), slope (eGFR-slope) and area under the curve (AUC).

Results
A total of 786 incident ESRD, 292 ACS and 410 death events occurred during the follow-up. In the multiple Cox regression, the fully adjusted hazard ratios (HRs) of progression to ESRD for each unit change in eGFR-CV, eGFR-PC, eGFR-AD, eGFR-slope, eGFR-AUC were 1.03 [95% confidence interval (CI) 1.02–1.04], 1.04 (1.03–1.04), 1.16 (1.14–1.18), 1.16 (1.14–1.17) and 1.04 (1.03–1.04), respectively. The adjusted HRs for incident ESRD comparing the extreme with the reference quartiles of eGFR-CV, eGFR-PC, eGFR-AD, eGFR-slope and eGFR-AUC were 2.67 (95% CI 2.11–3.38), 8.34 (6.33–10.98), 19.08 (11.89–30.62), 13.08 (8.32–20.55) and 6.35 (4.96–8.13), respectively. Similar direction of the effects on the risk of developing ACS and mortality was observed. In the 2 × 2 risk matrices, patients with the highest quartile of eGFR-CV and concomitantly with the most severely declining quartiles of any other longitudinal eGFR change scale had the highest risk of all outcomes.

Conclusions
The dynamics of eGFR changes, both overall variability and longitudinal changes, over the first year following pre-ESRD program enrollment are crucial prognostic factors for the risk of progression to ESRD, ACS and deaths among patients with CKD. A risk matrix combining the first-year eGFR variability and longitudinal change scales following pre-ESRD enrollment is a novel approach for risk characterization in CKD care. Randomized trials in CKD may be required to ascertain comparable baseline eGFR dynamics.
Tuberculosis and Leprosy Coinfection: A Perspective on Diagnosis and Treatment
Authors: Mangum Lisa , Kilpatrick Dustin , Stryjewska Barbara , Sampath Rahul 
Published: June 2018

AbstractBoth leprosy and tuberculosis (TB) are known to have similar geographic endemicity. In the setting of coinfection, interferon-gamma release assays (IGRAs) to detect latent TB can be falsely positive. We report a case of leprosy with a positive IGRA and asymptomatic active pulmonary TB. Minocycline and dapsone therapy was initiated during the workup for TB and changed to rifampin (Rif), isoniazid, pyrazinamide, and ethambutol, with the addition of dapsone once coinfection was confirmed. Our review of the literature revealed a preponderance of coinfection reported with borderline and lepromatous disease. Ten patients were diagnosed with leprosy as the first infection; 7 of these patients (70%) were treated with Rif before TB diagnosis, and 70% (7/10) of coinfected patients were on steroids. If treatment for leprosy is a consideration before ruling out active TB, then minocycline may temporarily replace the Rif. The dire implications of Rif monotherapy in undiagnosed coinfection may warrant chest radiography with or without sputum microbiology as routine initial workup for all leprosy cases.

Published: June 2018

Abstract

BACKGROUND
A number of vertical prolongations of the superior longitudinal fasciculus, which we refer to as the vertical rami (Vr), arise at the level of the supramarginal gyrus, directed vertically toward the parietal lobe.

OBJECTIVE
To provide the first published complete description of the white matter tracts (WMT) of the Vr, their relationship to the intraparietal and parieto-occipital sulci (IPS-POS complex), and their importance in neurosurgical approaches to the parietal lobe.

METHODS
Subcortical dissections of the Vr and WMT of the IPS were performed. Findings were correlated with a virtual dissection using high-resolution diffusion tensor imaging (DTI) tractography data derived from the Human Connectome Project. Example planning of a transparietal, transsulcal operative corridor is demonstrated using an integrated neuronavigation and optical platform.

RESULTS
The Vr were shown to contain component fibers of the superior longitudinal fasciculus (SLF)-II and SLF-III, with contributions from the middle longitudinal fasciculus merging into the medial bank of the IPS. The anatomic findings correlated well with DTI tractography. The line extending from the lateral extent of the POS to the IPS marks an ideal sulcal entry point that we have termed the IPS-POS Kassam-Monroy (KM) Point, which can be used to permit a safe parafascicular surgical trajectory to the trigone.

CONCLUSION
The Vr are a newly conceptualized group of tracts merging along the banks of the IPS, mediating connectivity between the parietal lobe and dorsal stream/SLF. We suggest a refined surgical trajectory to the ventricular atrium utilizing the posterior third of the IPS, at or posterior to the IPS-POS Point, in order to mitigate risk to the Vr and its considerable potential for postsurgical morbidity.

Abstract
Proximal junctional kyphosis (PJK) is a common problem after multilevel spine instrumentation for adult spinal deformity. Various anti-PJK techniques such as junctional tethers for ligamentous augmentation have been proposed. We present an operative video demonstrating technical nuances of junctional tether “weave” application. A 70-yr-old male with prior L2-S1 instrumented fusion presented with worsening back pain and posture. Imaging demonstrated pathological loss of lumbar lordosis (flat back deformity), proximal junctional failure, and pseudarthrosis. The patient had severe global and segmental sagittal malalignment, with sagittal vertical axis (SVA, C7-plumbline) measuring 22.3 cm, pelvic incidence (PI) 55°, lumbar lordosis (LL) 8° in kyphosis, pelvic tilt (PT) 30°, and thoracic kyphosis (TK) 6°. The patient gave informed consent for surgery and use of imaging for medical publication. Briefly, surgery first involved re-instrumentation with bilateral pedicle screws from T10 to S1. After right-sided iliac screw fixation (left-sided iliac screw fixation was not performed due to extensive prior iliac crest bone graft harvesting), we then completed a L2-3 Smith–Petersen osteotomy, extended L4 pedicle subtraction osteotomy, and L3-4 interbody arthrodesis with a 12° lordotic cage (9 × 14 × 40 mm). Cobalt Chromium rods were placed spanning the instrumentation bilaterally, and accessory supplemental rods spanning the PSO were attached. An anti-PJK junctional tether “weave” was then implemented using 4.5 mm polyethylene tape (Mersilene tape [Ethicon, Somerville, New Jersey]). Postoperative imaging demonstrated improved alignment (SVA 2.8 cm, PI 55°, LL 53°, PT 25°, TK 45°) and no significant neurological complications occurred during convalescence or at 6 mo postop.
Hypersensitivity reactions to beta-lactams in children
Authors: Graham François , Tsabouri Sophia , Caubet Jean-Christoph 
Published: June 2018

Purpose of review
To present the most recent evidence on beta-lactam hypersensitivity reactions in children.

Recent findings
Drug provocation tests (DPTs) are the gold standard when investigating beta-lactam allergy in children and evidence is increasingly supporting DPTs without skin tests as a safe approach when evaluating children with nonimmediate mild reactions to beta-lactams. Of note, data are limited in the adolescent population, and this attitude may not apply to this age group. Standardization of DPT protocols is required in nonimmediate reactions, as many protocols ranging from 1 to 10 days have been described. The optimal duration of DPT is still unknown, with extended protocols providing slightly more sensitivity and possible higher long-term compliance, at the expense of potential side effects associated with prolonged antibiotic use. On the other hand, 1-day DPTs will identify the vast majority of patients, and the rest will only develop a mild rash during a subsequent full treatment. The natural history of beta-lactam allergy in children is not well studied with recent evidence pointing to the resolution of most confirmed beta-lactam allergies after 3 years.

Summary
Further studies are needed for the standardization of DPT protocols and to confirm the favourable natural history of beta-lactam drug allergies in children. In addition, multicentric studies are required to confirm the increasingly accepted position of performing DPTs without skin tests in nonimmediate mild reactions to beta-lactams and to further evaluate the possibility of performing DPTs in benign immediate reactions to beta-lactams in children.
Monoclonal antibodies for the treatment of atopic dermatitis
Authors: Renert-Yuval Yael , Guttman-Yassky Emma 
Published: June 2018

Purpose of review
To evaluate the treatment revolution atopic dermatitis, the most common inflammatory skin disease, has been going through in recent years, thanks to breakthroughs in disease understanding, delineating the immune fingerprint of atopic dermatitis.

Recent findings
The treatment for moderate-to-severe atopic dermatitis patients has been largely unchanged for decades and relied on broad-acting immunosuppressants. A huge unmet need existed for effective, well tolerated and narrow-targeted therapeutics. Multiple therapies, targeting various aspects of the complex immune activation of atopic dermatitis, are now assessed in clinical trials, and hold promise for a new era in the treatment of atopic dermatitis, comparable with the treatment shift seen for psoriasis in the last decade. The first effective monoclonal antibody licensed for the treatment of atopic dermatitis, dupilumab, not only offers a much-needed systemic agent for moderate-to-severe patients but also provides strong evidence for the potential role of other monoclonal antibodies in disease management.

Summary
In this rapidly changing field, new atopic dermatitis-targeted monoclonal antibodies will be reviewed in light of the recently discovered pathomechanisms of the disease.
Systemic juvenile idiopathic arthritis and macrophage activation syndrome: update on pathogenesis and treatment
Authors: Yasin Shima , Schulert Grant S. 
Published: June 2018

Purpose of review
The past decade has seen substantial progress in defining the cause and pathogenesis of the chronic childhood arthropathy systemic juvenile idiopathic arthritis (SJIA) and its related complication macrophage activation syndrome (MAS). The purpose of this review is to describe and synthesize advances in this field, particularly since 2016, with the potential to transform clinical practice.

Recent findings
Newly developed MAS classification criteria have been further studied and validated in other diseases and populations, as well as a recently proposed score to distinguish MAS from familial hemophagocytic lymphohistiocytosis. There has also been substantial progress toward understanding the genetic underpinnings of SJIA and MAS, both through targeted study of specific genes and the results of a large genome-wide association study. The immunopathogenesis of SJIA has been further elucidated through several studies regarding the proinflammatory cytokines interleukin-18, interferon (IFN)γ, and how their interplay impacts emergence of MAS. Finally, big data studies integrating genomic information with immunophenotypes have potential to provide novel insights into disease mechanisms in SJIA.

Summary
Collectively, these research advances have significant implications regarding the classification and diagnosis of SJIA and MAS, and support a next generation of biologic treatments including kinase inhibitors and targeted interleukin-18 or IFNγ blockade.
Cardiovascular disease in systemic lupus erythematosus: an update
Authors: Liu Yudong , Kaplan Mariana J. 
Published: June 2018

Purpose of review
The mechanisms leading to the development of premature atherosclerosis and vascular injury in systemic lupus erythematosus (SLE) remain to be fully elucidated. This is a comprehensive review of recent research developments related to the understanding of cardiovascular disease (CVD) in lupus.

Recent findings
SLE patients with lupus nephritis display significantly increased risk of myocardial infarction and CVD mortality than SLE patients without lupus nephritis. SLE disease-related parameters could be taken into consideration when calculating CVD risks. The type I interferon pathway is detrimental to the vasculature and may contribute to the development of insulin resistance. The level of low-density granulocytes, a distinct subset of proinflammatory neutrophils present in SLE, was independently associated with coronary plaque burden and endothelial dysfunction. Invariant natural killer T cells may promote an atheroprotective effect in SLE patients with asymptomatic atherosclerotic plaques. Oxidized lupus high-density lipoprotein promotes proinflammatory responses in macrophages.

Summary
Recent discoveries have further strengthened the critical role of SLE-related immune dysregulation and metabolic disturbances in promoting accelerated CVD. Understanding how these pathogenic factors promote vascular injury may provide better molecular candidates for therapeutic targeting, and ultimately to improve CVD outcomes.

Study Design.
A cross-sectional study.

Objective.
To estimate the prevalence of adolescent idiopathic scoliosis (AIS) in cities in the state of São Paulo, Brazil, as well as to identify demographic, clinical, and lifestyle factors associated with AIS.

Summary of Background Data.
AIS is a common three-dimensional spinal deformity. Epidemiological data about the condition in the southern hemisphere are scarce, and Brazil has no public health policies to implement school-based scoliosis screening programs.

Methods.
We assessed 2562 adolescents between 10 and 14 years of age. The screening procedure included measurement of the angle of trunk rotation using a scoliometer in the Adams forward bend test and the radiographic examination.

Results.
The overall prevalence of AIS was 1.5% (95% confidence interval [CI]: 1%–1.9%). The AIS prevalence was higher among the females than among the males—2.2% (95% CI: 1.4%–2.9%) and 0.5% (95% CI: 0.1%–0.9%), respectively. The following factors were associated with the development of AIS: being female (OR = 4.7, 95% CI: 1.8–12.2; P = 0.001) and being in the 13- to 14-year age group (OR = 2.2; 95% CI: 1.0–4.8; P = 0.035). Double curves and right laterality were more common (59.4% and 56.8%, respectively), although the curves were of low magnitude (75% of the curves having a Cobb angle ≤22°), as was the progression factor (≤1.2 in 75% of the cases).

Conclusion.
The prevalence of AIS in cities within the state of São Paulo was similar to that reported in the literature, was higher among females, and was higher during puberty (13–14 years of age). Because puberty occurs later for males than for females, the recommendation to screen both sexes at 10 to 14 years of age should be reconsidered.

Fatigue, a major still underestimated issue
Authors: Ripamonti Carla Ida , Antonuzzo Andrea , Bossi Paolo , Cavalieri Stefano , Roila Fausto , Fatigoni Sonia 
Published: June 2018

Purpose of review
Cancer-related fatigue (CRF) is a frequent and distressing symptom present at any stage of the disease. However, it is still underreported, rarely properly assessed and undertreated.

Recent findings
There are international guidelines available, but also several barriers to their implementation into clinical practice.

Summary
According to guidelines, all patients should be clinically screened for CRF on regular basis, at the initial cancer visit and at intervals during every clinic visit, also at posttreatment follow-up visits. Generally, any treatable contributing factors should be identified and possibly treated. After the concomitant factors have been improved or removed, pharmacological and or nonpharmacological treatments of CRF can be considered.
Further research is needed to better understand the causes, the better treatments, the easier assessment tool for CRF for clinical practice and to identify barriers and facilitators to implementing CRF guidelines.
Primary Cutaneous Follicle Center Lymphoma Clear Cell Variant: Expanding the Spectrum of Cutaneous Clear Cell Neoplasms
Authors: Cassisa Angelo , Colpani Francesco , Rinaldi Rosa , Cima Luca 
Published: June 2018

Abstract:
Primary cutaneous follicle center lymphoma is the most frequent cutaneous B-cell lymphoma despite the fact that is an uncommon disease. Mild biological behavior and good prognosis characterized this neoplasm with a low aggressiveness compared with classic nodal follicular lymphoma (FL). Rare histological variants have been described. We present the case of a 72-year-old man who underwent surgery for a cutaneous nodule on his left scapula. The biopsy showed a dermal clear cell proliferation arranged in a nodular and diffuse pattern. The cells stained positive for CD20 and Bcl-6 supporting B-cell follicular differentiation. The final diagnosis was “primary cutaneous follicle center lymphoma” with “clear cell changes” according to the 2016 World Health Organization classification of lymphoid neoplasms. Additional tests to rule out a systemic involvement were performed. The prognosis was favorable with a disease-free survival of 7 years after complete surgical excision. It has been assumed that cutaneous tumors composed of clear cells may have an epithelial, melanocytic, adnexal, mesenchymal, or metastatic origin. The correct histopathological diagnosis required immunohistochemistry and even molecular techniques. To the best of our knowledge, this is the first report of a cutaneous clear cell lymphoma and of a FL with clear cell features. Our findings provide evidence that the heterogeneity of FL is greater than previously thought and expand the spectrum of differential diagnosis in cutaneous clear cell neoplasms. Dermatopathologists should be aware of this entity and should comprise a PanB marker in their first- or second-line immunohistochemistry for the correct diagnosis of a dermal clear cell proliferation.
Normative Database and Color-code Agreement of Peripapillary Retinal Nerve Fiber Layer and Macular Ganglion Cell-inner Plexiform Layer Thickness in a Vietnamese Population
Authors: Perez Claudio I. , Chansangpetch Sunee , Thai Andy , Nguyen Anh-Hien , Nguyen Anwell , Mora Marta , Nguyen Ngoc , Lin Shan C. 
Published: June 2018

Purpose:
Evaluate the distribution and the color probability codes of the peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell-inner plexiform layer (GCIPL) thickness in a healthy Vietnamese population and compare them with the original color-codes provided by the Cirrus spectral domain–optical coherence tomography.

Methods:
This is a cross-sectional study. We recruited nonglaucomatous Vietnamese subjects and constructed a normative database for peripapillary RNFL and macular GCIPL thickness. The probability color-codes for each decade of age were calculated. We evaluated the agreement with κ coefficient between optical coherence tomography color probability codes with Cirrus built-in original normative database and the Vietnamese normative database.

Results:
In total, 149 eyes of 149 subjects were included. The mean age of enrollees was 60.77 (±11.09) years, with a mean spherical equivalent of +0.65 (±1.58) D and mean axial length of 23.4 (±0.87) mm. Average RNFL thickness was 97.86 (±9.19) µm and average macular GCIPL was 82.49 (±6.09) µm. Agreement between original and adjusted normative database for RNFL was fair for average and inferior quadrant (κ=0.25 and 0.2, respectively); and good for other quadrants (range, κ=0.63 to 0.73). For macular GCIPL κ agreement ranged between 0.39 and 0.69. After adjusting with the normative Vietnamese database, the percent of yellow and red color-codes increased significantly for peripapillary RNFL thickness.

Conclusions:
Vietnamese population has a thicker RNFL in comparison with Cirrus normative database. This leads to a poor color-code agreement in average and inferior quadrant between the original and adjusted database. These findings should encourage to create a peripapillary RNFL normative database for each ethnicity.
Change in Eyelid Carcinoma T Category With Use of the 8th Versus 7th Edition of the American Joint Committee on Cancer: Cancer Staging Manual
Authors: Ding Stephanie , Sagiv Oded , Guo Yunxia , Kandl Thomas J. , Thakar Sudip D. , Esmaeli Bita 
Published: June 2018

Purpose:
To evaluate the frequency and nature of changes in T category when eyelid carcinomas are staged using the criteria in the 8th edition instead of the 7th edition of the American Joint Committee on Cancer staging manual.

Methods:
Following Institutional Review Board approval, a retrospective review was conducted for all consecutive patients with the diagnosis of eyelid carcinoma treated by the senior author from January 2012 through December 2016. After a review of the clinical and pathologic data, each patient’s disease was staged using both the 7th-edition and 8th-edition American Joint Committee on Cancer criteria for eyelid carcinomas. Changes in T categories between the 2 staging systems were examined.

Results:
The review initially identified 167 patients with the diagnosis of eyelid carcinoma. Four patients were excluded because of incomplete or unclear data. The remaining 163 patients included 78 men and 85 women aged 21 to 97 years (median, 68 years). Eighty-two patients had basal cell carcinoma; 35, squamous cell carcinoma; 32, sebaceous carcinoma; 6, mucinous eccrine carcinoma; 3, Merkel cell carcinoma; 3, adenocarcinomas; and 2, adnexal carcinoma. The most common T category according to the 7th-edition criteria was T2a; the most common T category according to the 8th-edition criteria was T1b. Of the 163 patients, 64 (39%) had a lower T category with the 8th-edition than with the 7th-edition criteria, 59 (36%) had a higher T category, and 40 (25%) had the same T category.

Conclusions:
Application of the 8th-edition American Joint Committee on Cancer criteria for eyelid carcinoma changed the T category in 75% of patients. In general, the new 8th-edition American Joint Committee on Cancer tumor, node, metastasis (TNM) designations allow for a more objective and consistent designation of the T category.
