Radar Remote Sensing of Precipitation in High Mountains: Detection and Characterization of Melting Layer in the Grenoble Valley, French Alps
Authors: Khanal Anil Kumar , Delrieu Guy , Cazenave Frédéric , Boudevillain Brice 
Published: December 2019

The RadAlp experiment aims at developing advanced methods for rain and snow estimation using weather radar remote sensing techniques in high mountain regions for improved water resource assessment and hydrological risk mitigation. A unique observation system has been deployed in the French Alps, Grenoble region. It is composed of a Météo-France operated X-band MOUC radar (volumetric, Doppler and polarimetric) on top of the Mt Moucherotte (1920 m ASL), the X-band XPORT research radar (volumetric, Doppler, polarimetric), a K-band micro rain radar (MRR, Doppler, vertically pointing) and in situ sensors (rain gauges, disdrometers), latter three operated on the Grenoble campus (220 m ASL). Based on the observation that the precipitation phase changes at/below the elevation of mountain-top MOUC radar for more than 60% of the significant events, an algorithm for ML identification has been developed using valley-based radar systems: it uses the quasi vertical profiles of XPORT polarimetric measurements (horizontal and vertical reflectivity, differential reflectivity, cross-polar correlation coefficient) and the MRR vertical profiles of apparent falling velocity spectra. The algorithm produces time series of the altitudes and values of peaks and inflection points of the different radar observables. A literature review allows us to link the micro-physical processes at play during the melting process with the available polarimetric and Doppler signatures, e.g., (i) regarding the altitude differences between the peaks of reflectivity, cross-polar correlation coefficient and differential reflectivity, as well as (ii) regarding the co-variation of the profiles of Doppler velocity spectra and cross-polar correlation coefficient. A statistical analysis of the ML based on 42 rain events (98 h of XPORT data) is then proposed. Among other results, this study indicates that (i) the mean value of the ML width in Grenoble is 610 m with a standard deviation of 160 m; (ii) the mean altitude difference between the horizontal reflectivity and the ρ H V peaks is 90 m and the mean altitude difference between the ρ H V and Zdr peaks is 30 m; (iii) even for the limited rainrate range in the dataset (0–8.5 mm h − 1 ), the “intensity effect” is clear on the reflectivity profile and the ML width, as well as on polarimetric variables such as ρ H V peak value and the Zdr enhancement in the upper part of the profile. On the contrary, the study of both the “density effect” and the influence of the 0 ° C isotherm altitude did not yield significant results with the considered dataset; (iv) a principal component analysis on one hand shows the richness of the dataset since the first 2 PCs explain only 50% of the total variance and on the other hand the added-value of the polarimetric variables since they rank high in a ranking of the total variance explained by individual variables.

Purpose: Specialisation in hepatopancreatobiliary (HPB) surgery has evolved over the past few decades based on better understanding of the biology and the behaviour of the diseases. In this review from a specialised HPB service, we aim to provide an overview of the HPB oncological cases managed in a tertiary care cancer hospital. Methods: All cases of HPB malignancies treated in our hospital between October 2014 and September 2015 were included in the study. Clinical findings, operative details and short-term post-operative outcomes were assessed from a prospectively managed database. Results: A total of 65 oncological procedures were performed over 1 year. These included 23 hepatic resections, 27 pancreaticoduodenectomies, 5 radical surgeries for gallbladder cancer, 2 distal pancreatectomy and 8 nephrectomies with exploration of the inferior vena cava. One patient successfully underwent Associated Liver Partition with Portal vein ligation and staged hepatectomy (ALPPS Procedure), which to our knowledge was the rst ALPPS procedure carried out in Pakistan. Conclusion: The short-term experience of patients managed in specialised HPB unit has shown good outcomes.There is a need for establishing HPB units in most tertiary care hospitals in the country.

Published: December 2019

Purpose: Aberrant hepatic arterial anatomy poses a challenge for surgeon during pancreaticoduodenectomy (PD). These anomalies are best picked up on pre-operative imaging to avoid inadvertent injury to the aberrant vasculature resulting in liver ischaemia or biliary-enteric anastomotic failure. We present our experience of dealing with aberrant hepatic vessels during PD. Methods: Patients with aberrant hepatic vasculature who underwent PD between September 2014 and August 2015 were included in the study. We used artery rst technique for dissection in cases identified on pre operative imaging. Aberrations were classed according to Hiatt classi cation. Results: A total of 23 PD were performed with aberrant arterial anatomy in 10 (43%) cases. These vessels were recognised and preserved in nine cases. In one patient, the replaced right hepatic artery (RRHA) arising from superior mesenteric artery (SMA) was coursing through pancreatic parenchyma needing resection and reconstruction with uneventful post-operative recovery. We also identified one RRHA arising from SMA coursing lateral to common bile duct and entering liver parenchyma in gallbladder fossa. Conclusion: Aberrant hepatic arterial anomalies are common and should ideally be picked up by pre-operative imaging. It is possible to preserve these vessels in most cases with careful surgical dissection using artery first technique. Surgeons performing PD should be well versed with the aberrant vascular anatomy to minimise any inadvertent damage. Key words: Aberrant hepatic artery, artery first technique, pancreaticoduodenectomy

Published: December 2019

Background: A high number of clinical T1 (cT1) stage renal cell carcinoma (RCC) is upstaged to pathological T3a (pT3a) stage on histopathological findings. Several study results show that there is no survival difference among those cT1 stage who are upstaged on histopathological findings to those who remain pT1 stage RCC.Objectives: The objectives of this study were to assess any survival difference for cT1 stage renal cell carcinoma (RCC) which is upstaged to pT3a stage as compared to those which remain pT1 stage RCC on histopathological findings.Materials and Methods: It was a retrospective cohort study looking at patient aged ≥18 years with cT1 RCC who underwent nephrectomy between January 2006 and December 2016. Patients were divided into two groups based on histopathological findings (pT1 vs. pT3a). Survival was analysed for the two groups using Kaplan–Meier method, and the difference in survival was calculated using log-rank model.Results: The study included 187 patients. The mean age at presentation was 52.56 years, with 58.3% of the patients being male while 41.7% were female. The most common presentation was incidental diagnosis (50.3%). Overall5-year survival for cT1a and pT1a RCC was 68% while that for cT1a and pT3a RCC was 100%. There was no significant survival difference among the two groups (P = 0.316). The overall 5-year survival for cT1b and pT1b RCC was 81% while that for cT1b and pT3a was 65%. There was no significant survival difference among the two groups (P = 0.136).Conclusion: We found no survival difference in cT1 RCC who were upstaged to pT3a on histopathology as compared to cT1 RCC-staged pT1 on histopathology.Key words: Clinical T1 stage, pathological T3a stage, radical nephrectomy, renal cell carcinoma, survival
WHAT IS YOUR UNDERSTANDING OF SPINAL AND EPIDURAL ATTEMPT?
Authors: Yahya Salman , Siddiqui Athar Mukhtar 
Published: December 2019

Background: The practice of spinal and epidural anaesthesia is well established the world over for a number of years. Sighting of spinal or epidural is conducted through various approaches at various levels of the spinal column. The number of attempts has its correlation with the post-spinal and epidural complications.Aim: The aim is to gather information about the understanding among the anaesthetists about the spinal/epidural attempt.Materials and Methods: A pro forma comprising of nine closed-loop questions was distributed to all the participants in the study, and they were requested to fill it anonymously and placed it back in a designated sealed box in anaesthetic office.Results: A total of 20 pro formas were distributed, and all of them received back with 100% responses. All the participants accepted universally that attempting through another space makes it a second attempt. One of the respondents thought any backward movement means 2nd attempt, the majority of the responders thought it does not count as an attempt. Almost everyone considered another attempt if a needle is completely withdrawn and enters through another puncture site whether through a midline or paramedian approach.Conclusion: Most of the complications after neuraxial blockade are associated with the number of attempts alongside other factors that may play a role. A universal definition of a spinal and epidural attempt may decrease the complications associated with the central neuraxial blockade.Key words: Epidural, single attempt, spinal

Abstract
We present X-ray and radio monitoring observations of the gamma-ray binary PSR J2032+4127/MT91 213 during its periastron passage in late 2017. Dedicated Chandra, XMM-Newton, NuSTAR X-ray observations, and Very Large Array radio observations of this long orbit (50 yr), 143 ms pulsar/Be star system clearly revealed flux and spectral variability during the passage. The X-ray spectrum hardened near periastron, with a significant decrease in the power-law (PL) photon index from Γ ≈ 2 to 1.2 and evidence of an increased absorption column density. We identified a possible spectral break at a few keV in the spectrum that suggests synchrotron cooling. A coincident radio and X-ray flare occurred one week after periastron, which is possibly the result of the pulsar wind interacting with the Be stellar disk and generating synchrotron radiation. However, a multiwavelength comparison indicates that the X-ray and radio spectra cannot be simply connected by a single PL component. Hence, the emission in these two energy bands must originate from different particle populations.

Abstract
Transit spectroscopy of terrestrial planets around nearby M dwarfs will be a primary goal of space missions in coming decades. Three-dimensional climate modeling has shown that slow-synchronous rotating terrestrial planets may develop thick clouds at the substellar point, increasing the albedo. For M dwarfs with T
eff > 3000 K, such planets at the inner habitable zone (IHZ) have been shown to retain moist greenhouse conditions, with enhanced stratospheric water vapor (fH
2O > 10−3) and low Earth-like surface temperatures. However, M dwarfs also possess strong UV activity, which may effectively photolyze stratospheric H2O. Prior modeling efforts have not included the impact of high stellar UV activity on the H2O. Here, we employ a 1D photochemical model with varied stellar UV, to assess whether H2O destruction driven by high stellar UV would affect its detectability in transmission spectroscopy. Temperature and water vapor profiles are taken from published 3D climate model simulations for an IHZ Earth-sized planet around a 3300 K M dwarf with an N2–H2O atmosphere; they serve as self-consistent input profiles for the 1D model. We explore additional chemical complexity within the 1D model by introducing other species into the atmosphere. We find that as long as the atmosphere is well-mixed up to 1 mbar, UV activity appears to not impact detectability of H2O in the transmission spectrum. The strongest H2O features occur in the James Webb Space Telescope MIRI instrument wavelength range and are comparable to the estimated systematic noise floor of ∼50 ppm.
