A Diabetic Woman with Insulin Injection Abscesses
Authors: Darwin Evan , Chen Lucy , Nichols Anna , Romanelli Paolo 
Published: June 2017

A 50-year-old diabetic woman developed multiple abscesses after daily injections of subcutaneous regular human insulin. Initial cultures from the draining fluid revealed no organisms, and the patient was unresponsive to multiple courses of antibiotics including doxycycline, amoxicillin/clavulanic acid, and intravenous vancomycin and piperacillin/tazobactam. After consulting dermatology, the patient underwent punch biopsy and tissue culture. The tissue culture grew mycobacterium fortuitum after 22 days of incubation. The patient was diagnosed with non-tuberculous mycobacterial infection and began to improve after treatment with ciprofloxacin. Non-tuberculous mycobacteria are common in the environment, although systemic manifestations of infection are rare in healthy individuals. In this paper, we discuss the risk factors, diagnostic methods, and treatment recommendations for these types of infections.

Published: June 2017

Background: Hypothyroidism is a common endocrine disorder which has been linked to the development of hyponatremia. However, the data supporting the development of hyponatremia is inadequate and confusing.Aims and Objectives: Therefore this study was conducted to investigate an association between hypothyroidism and hyponatremia and to correlate it with other related parameters like renal function status.Material and Methods: Retrospective analysis of laboratory records of one hundred fifty individuals with TSH level above the normal served as cases and one hundred fifty one individuals with normal TSH served as controls.Results: Hyponatremia(<135mEq/L) was observed in only twenty-one percent of cases of hypothyroidism. Although patients of hypothyroidism had a significantly lower sodium levels than controls, this was not evident with severity of disease. A high creatinine level evident in the overt cases did not affect the sodium level, although the chloride level was reduced.Conclusion: The present study showed that hyponatremia is not a commonly associated with hypothyroidism and screening for hyponatremia is not essential in such patients.Asian Journal of Medical Sciences Vol.8(4) 2017 6-10

Abstract
We have observed the protoplanetary disk of the well-known young Herbig star HD 142527 using ZIMPOL polarimetric differential imaging with the very broad band (∼600–900 nm) filter. We obtained two data sets in 2015 May and 2016 March. Our data allow us to explore dust scattering around the star down to a radius of ∼0.″025 (∼4 au). The well-known outer disk is clearly detected at higher resolution than before and shows previously unknown substructures, including spirals going inward into the cavity. Close to the star, dust scattering is detected at high signal-to-noise ratio, but it is unclear whether the signal represents the inner disk, which has been linked to the two prominent local minima in the scattering of the outer disk that are interpreted as shadows. An interpretation of an inclined inner disk combined with a dust halo is compatible with both our and previous observations, but other arrangements of the dust cannot be ruled out. Dust scattering is also present within the large gap between ∼30 and ∼140 au. The comparison of the two data sets suggests rapid evolution of the inner regions of the disk, potentially driven by the interaction with the close-in M-dwarf companion, around which no polarimetric signal is detected.
The Dynamical Origin of the Local Arm and the Sun's Trapped Orbit

Published: June 2017

Abstract
The Local Arm of the Milky Way, a short spiral feature near the Sun whose existence has been known for decades, was recently observed in detail with different tracers. Many efforts have been dedicated to elaborate plausible hypotheses concerning the origin of the main spiral arms of the Galaxy; however, up to now, no specific mechanism for the origin of the Local Arm has been proposed. Here we explain, for the first time, the Local Arm as an outcome of the spiral corotation resonance, which traps arm tracers and the Sun inside it. We show that the majority of maser sources belonging to the Local Arm, together with the Sun, evolve inside the corotation resonance, never crossing the main spiral arms but instead oscillating in the region between them. This peculiar behavior of the Sun could have numerous consequences for our understanding of the local kinematics of stars, the Galactic Habitable Zone, and the solar system evolution.
Analytic Expressions for the Inner-rim Structure of Passively Heated Protoplanetary Disks

Published: June 2017

Abstract
We analytically derive the expressions for the structure of the inner region of protoplanetary disks based on the results from the recent hydrodynamical simulations. The inner part of a disk can be divided into four regions: a dust-free region with a gas temperature in the optically thin limit, an optically thin dust halo, an optically thick condensation front, and the classical, optically thick region, in order from the innermost to the outermost. We derive the dust-to-gas mass ratio profile in the dust halo using the fact that partial dust condensation regulates the temperature relative to the dust evaporation temperature. Beyond the dust halo, there is an optically thick condensation front where all the available silicate gas condenses out. The curvature of the condensation surface is determined by the condition that the surface temperature must be nearly equal to the characteristic temperature ∼1200 K. We derive the midplane temperature in the outer two regions using the two-layer approximation, with the additional heating by the condensation front for the outermost region. As a result, the overall temperature profile is step-like, with steep gradients at the borders between the outer three regions. The borders might act as planet traps where the inward migration of planets due to gravitational interaction with the gas disk stops. The temperature at the border between the two outermost regions coincides with the temperature needed to activate magnetorotational instability, suggesting that the inner edge of the dead zone must lie at this border. The radius of the dead zone inner edge predicted from our solution is ∼2–3 times larger than that expected from the classical optically thick temperature.

Published: June 2017

Purpose: To compare objective image quality at distant, intermediate, and near foci with the corresponding visual acuity (VA) in patients symmetrically implanted with 5 different diffractive multifocal intraocular lenses (IOLs) (ReSTOR SV25T0, Tecnis ZKB00, Tecnis ZLB00, AT LISA 809, and AT LISA Tri 839MP) and a monofocal lens (Tecnis ZA9003) 3 months after cataract intervention. Methods: Objective image quality, measured as the area under the modulation transfer function curve (AMTF), was tested in vitro in an eye model. In addition, corrected distance visual acuity and distance-corrected intermediate and near visual acuities (DCIVA and DCNVA) were assessed in a group of 79 patients, randomly implanted with one of the lenses. Results: Image quality and VA at the distant focus was good for all lens designs, but was similarly compromised at the intermediate focus, where the best DCIVA corresponded to the low add ZKB00. At the near focus, the monofocal lens and the distance dominant SV25T0 had the worst AMTF values, with the ZLB00 presenting the best DCNVA. The relationship between AMTF and VA was found not to be linear, with VA being similarly good for AMTF values over a certain threshold. Conclusions: Visual acuity of pseudophakic patients reflected the optical quality of the specific IOL design within a certain range of measurements, beyond which maximum VA is limited by other ocular, optical, and neuropsychophysical factors.

Published: June 2017

Background The metabolism of vitamin D is complex, its receptor (VDR) and proteins encoded by the genes CYP27B2 and CYP24A1 can influence vitamin D serum levels. The aim of this study was to investigate the relationship of the polymorphisms of VDR (ApaI and BsmI), CYP27B1 and CYP24A1 with serum vitamin D levels in both forms, 25(OH)D3 (circulating form) and 1,25(OH)2D3 (active form), in colorectal cancer (CRC) patients. Methods One hundred fifty-two CRC patients and 321 controls were included. DNA was extracted from peripheral blood. Polymorphisms of BsmI and ApaI were identified by PCR-RFLP. Those of CYP24A1 (rs6013897, rs158552 and rs17217119) and CYP27B1 (rs10877012) were determined by gene sequencing. Results The median serum levels of circulating vitamin D were not different between CRC patients and controls; however, the percentage of those with deficient vitamin D was higher in patients with cancer. The active form of the vitamin D was higher in CRC patients. VDR, CYP27B1 and CYP24A1 polymorphic genotypes had no influence on serum levels of circulating vitamin D. The correlation between circulating and active vitamin D forms was lower among patients with CRC, regardless of the presence or absence of any genetic polymorphism. The mean serum levels of active vitamin D were higher among patients with polymorphic genotype variants of Apa1 or Bsm1. Conclusions CRC patients had a higher frequence of insufficient vitamin D and a higher concentration of active vitamin D. These concentration were higher between patients with polymorphic genotypes variants of ApaI and BsmI, CYP24A1 and CYP27B1. Polymorphic genotypes cause a lower correlation between the forms of vitamin D.

Tailgut cysts, also called retrorectal cystic hamartomas, are rare findings that usually occur in the retrorectal space. The incidence is estimated to be about 1 in 40,000. The aim of our review is to evaluate the potential pitfalls in the diagnosis of this rare pathologic condition, according to diagnostic procedures for this rare but misleading and subtle entity. We conducted a Medline literature review of the English literature discussing tailgut cysts in female patients. We concentrated on imaging technology used for diagnosis in gynecologic patients. For our search, we used the key words “tailgut cyst”, “retrorectal cystic hamartoma”, “gynecology”, focusing on clinical presentation, imaging technology used for diagnosis, presence of malignancy, and misdiagnosis with more common gynecologic pathology. Our search revealed 143 articles during the years 1975–2016 and, of these, 30 articles describing 91 female patients were considered. We concluded that tailgut cyst should be included in the differential diagnosis of pelvic lesions in gynecologic patients.

Introduction Cephalic arch stenosis is one of the most common reasons for repeated endovascular intervention and eventual abandonment of access in hemodialysis patients. There is no prediction model to identify risk factors for recurrent cephalic arch stenosis. We have developed a mathematical model to predict the need for reintervention in brachiocephalic (BC) fistulas with recurrent cephalic arch stenosis. Methods Single-center retrospective analysis of 143 patients with a BC fistula referred to the vascular clinic for access dysfunction who underwent cephalic arch angioplasty were included for the analysis. Twelve-month post-index angioplasty data were analyzed using parametric, non-parametric and multiple regression models using SPSS software. Results The mean need for re-intervention in 1 year since first index visit was 2.46 ± 1.404. Statistically significant correlation (p≤0.001) for re-intervention was observed with the severity of stenosis at index visit, access flow, vessel wall diameter proximal to the stenosis, average venous pressure >50% of the delivered blood flow rate and prolonged bleeding for >30 minutes as a reason for referral. Three equations have been derived for calculating the need for re-intervention based on the diameter of the vessel wall proximal to the stenosis. Conclusions Risk stratification of BC fistulas utilizing the above parameters could enable clinicians to identify accesses that are at risk for multiple re-interventions. Early identification of accesses that are at high risk for re-interventions at the cephalic arch might prolong access survival and reduce the cost for intervention by utilizing alternate strategies.

Published: June 2017

Abstract
A proton (1H) NMR spectroscopic method was established for the quality assessment of vegetable oils. To date, several research studies have been published demonstrating the high potential of the NMR technique in lipid analysis. An interlaboratory comparison was organized with the following main objectives: (1) to evaluate an alternative analysis of edible oils by using 1H NMR spectroscopy; and (2) to determine the robustness and reproducibility of the method. Five different edible oil samples were analyzed by evaluating 15 signals (free fatty acids, peroxides, aldehydes, double bonds, and linoleic and linolenic acids) in each spectrum. A total of 21 NMR data sets were obtained from 17 international participant laboratories. The performance of each laboratory was assessed by their z-scores. The test was successfully passed by 90.5% of the participants. Results showed that NMR spectroscopy is a robust alternative method for edible oil analysis.

MODIFICATION OF WAVE SPECTRA ON THE CONTINENTAL SHELF AND IN THE SURF ZONE
Authors: Bretschneider Charles L. 
Published: June 2017

This paper discusses the problem pertaining to the modification of the wave spectrum over the continental shelf. Modification factors include bottom friction, percolation, refraction, breaking waves, ocean currents, and regeneration of wind waves in shallow water, among other factors. A formulation of the problem is presented but no general solution is made, primarily because of lack of basic data. Several special solutions are presented based on reasonable assumptions. The case for a steep continental shelf with parallel bottom contours and wave crests parallel to the coast and for which bottom friction is neglected has been investigated. For this case it is found that the predominant period shifts toward longer periods. The implication is, for example, that the significant periods observed along the U. S. Pacific coast are longer than those which would be observed several miles westward over deep water.
The case for a gentle continental shelf with parallel bottom contour and wave crests parallel to the coast and for which bottom friction is important has also been investigated. For this case it is found that the predominant period shifts toward shorter periods as the water depth decreases. The implication is, for example, that the significant periods observed in the shallow water over the continental shelf are shorter than those which would be observed beyond the continental slope. In very shallow water, because shoaling becomes important, a secondary peak appears at higher periods.
The joint distribution of wave heights and wave periods is required in order to determine the most probable maximum breaking wave, which can be of lesser height than the most probable maximum non-breaking wave. In very shallow water the most probable maximum breaking wave which first occurs would be governed by the breaking depth criteria, whereas in deepwater wave steepness can also be a governing factor. It can be expected that in very shallow water the period of the most probable maximum breaking wave should be longer than the significant period; and for deeper water the period of the most probable maximum breaking wave can be less than the significant period.
Percolation connectivity, pore size, and gas apparent permeability: Network simulations and comparison to experimental data

AbstractWe modeled single‐phase gas flow through porous media using percolation networks. Gas permeability is different from liquid permeability. The latter is only related to the geometry and topology of the pore space, while the former depends on the specific gas considered and varies with gas pressure. As gas pressure decreases, four flow regimes can be distinguished as viscous flow, slip flow, transition flow, and free molecular diffusion. Here we use a published conductance model presumably capable of predicting the flow rate of an arbitrary gas through a cylindrical pipe in the four regimes. We incorporated this model into pipe network simulations. We considered 3‐D simple cubic, body‐centered cubic, and face‐centered cubic lattices, in which we varied the pipe radius distribution and the bond coordination number. Gas flow was simulated at different gas pressures. The simulation results showed that the gas apparent permeability kapp obeys an identical scaling law in all three lattices, kapp ~ (z‐zc)β, where the exponent β depends on the width of the pipe radius distribution, z is the mean coordination number, and zc its critical value at the percolation threshold. Surprisingly, (z‐zc) had a very weak effect on the ratio of the apparent gas permeability to the absolute liquid permeability, kapp/kabs, suggesting that the Klinkenberg gas slippage correction factor is nearly independent of connectivity. We constructed models of kapp and kapp/kabs based on the observed power law and tested them by comparison with published experimental data on glass beads and other materials.
