Lesiones ungueales y cutáneas por Scytalidium dimidiatum en Medellín (Colombia), 1990-1999. Presentación de 128 casos y revisión del problema del nombre del agente
Authors: Escobar de Villalobos Marta Lucía , Carmona Fonseca Jaime 
Published: March 2023

Objetivo: Revisar el problema de la denominación del agente y presentar los rasgos epidemiológicos de 128 casos de lesiones en uñas o en piel por Scytalidium dimidiatum. Diseño: Estudio descriptivo, en parte retrospectivo (1990-1996) y en parte prospectivo (1997-1999). Marco de referencia: hasta hace poco tiempo hubo problemas con la nomenclatura del agente, pero ahora existen los argumentos para despejar las dificultades y ese es el primer objetivo del trabajo: presentar esos argumentos e indicar la manera de usar bien uno u otro nombre. Por otra parte, la importancia del S. dimidiatum como causa de lesiones en humanos aumenta cada día. Este informe, restringido a lesiones en uñas y piel, recoge una cifra muy alta de pacientes (128 casos), correspondientes al lapso 1990-1999. Métodos: los autores revisaron cada uno de los registros de laboratorio y, aplicando criterios de consenso, resolvieron las dudas. Se utilizaron criterios estándar de identificación micológica. El análisis estadístico de los datos se hizo con el programa EpiInfo versión 6.04. y consistió, principalmente, en evaluar la asociación de variables con la chi cuadrada y en comparar posiciones de datos continuos y ordenados según su magnitud con la prueba H de Kruskal-Wallis. Resultados: los diferentes nombres del agente (Nattrassia mangiferae, Scytalidium dimidiatum, Scytalidium hialinum, Scytalidium lignicola, Hendersonula toruloidea) deben usarse en situaciones precisas, que se describen aquí. Se estudiaron 128 muestras de las cuales se aisló por cultivo Scytalidium dimidiatum: 102 en uñas (92% en pies) y 26 en lesiones extraungueales (73% interdigitales en pies). Las características epidemiológicas de un caso típico de lesión ungueal por S. dimidiatum indican que en el 41% de las veces es una mujer, de 21 a 49 años, que usa zapatos de riesgo, que tiene hiperhidrosis y practica el deporte. Por otra parte, los rasgos epidemiológicos de un caso típico de lesión extraungueal por S. dimidiatum son semejantes a los anteriores pero en el 69% de los casos se trata de un hombre. El examen directo fue positivo en 97% de los casos y las estructuras más frecuente fueron los «restos de micelio» (74%), seguidos de hifas septadas solas o con clamidoconidias (21%) y de blastoconidias solas o acompañadas de seudomicelios (5%). No hubo diferencia significativa en el resultado del examen directo entre las lesiones en uñas y fuera de ellas.

Se ha considerado al Síndrome de Respuesta Inflamatoria Sistémica (SRIS), a la sepsis y a las complicaciones que de ellos se derivan, como responsables de un número importante de hospitalizaciones y consultas en los servicios de urgencias en centros de tercer nivel. En nuestros medios muchos aspectos relacionados con la epidemiología, la presentación clínica y la microbiología de estas entidades se encuentran aún por definir. Diseño: estudio de cohorte longitudinal. Población de estudio: pacientes hospitalizados por urgencias en dos hospitales de referencia, con criterios de SRIS de adquisición extrahospitalaria y etiología no traumática, entre agosto 1 de 1998 y marzo 31 de 1999. Metodología: recolección, en el momento de la admisión en urgencias, de variables relacionadas con las características clínicas, epidemiológicas y microbiológicas de la cohorte. Resultados: 503 pacientes ingresaron al estudio. El rango de edad osciló entre 14 y 97 años, con un promedio de 49 años. El 46.5% fueron mujeres. El 27.8% fueron amas de casa, desempleados el 12.7% y agricultores el 4.9%. El tiempo de hospitalización promedio fue de 11.3 días. Los principales diagnósticos de ingreso fueron neumonía, sepsis e infección de tejidos blandos. Los gérmenes más frecuentemente aislados en sangre fueron Staphylococcus aureus, Streptococcus pneumoniae y Escherichia coli, Las complicaciones más frecuentes fueron choque (17.2%) y síndrome de dificultad respiratoria (13.1%). El 58.8% de los pacientes presentaron síndrome de origen infeccioso sin germen cultivado, y entre estos los síndromes predominantes fueron neumonía e infecciones de tejidos blandos. Conclusiones: el SRIS y la sepsis son entidades frecuentes en nuestros hospitales. La población estudiada es heterogénea en cuanto a sus características epidemiológicas, microbiológicas y la edad de los pacientes, pero parece diferenciarse claramente de otras latitudes en cuanto a población más joven y menor tiempo de estancia hospitalaria. Aunque clínica mente se tenga un síndrome infeccioso, en un número importante de pacientes no se aislan los gérmenes responsables. Los principales diagnósticos de ingreso y los microorganismos documentados muestran similitudes con lo informado en la literatura mundial.

Published: March 2023

Lateral elbow tendinopathy is a common condition affecting two to three percent of the population. While non-operative management is the mainstay of treatment, 10-15% remain refractory. Ultrasonic percutaneous tenotomy is a recent therapeutic option for clinicians to treat lateral elbow tendinopathy. The goal of this study was to evaluate the survival rate of ultrasonic percutaneous tenotomy in the treatment of lateral elbow tendinopathy. 83 patients underwent ultrasonic percutaneous tenotomy from September 2015 to August 2018 and met full inclusion criteria to participate. 63 patients consented to enroll in the study, with 50 (79.4%) completing the postoperative questionnaire. Data obtained included range of motion, patients’ report of improvement, Quick Dash Score (Q-Dash), Visual Analogue Scale (VAS) pain, VR 12, Mayo Elbow Performance, patient satisfaction, further post-operative adjunct procedures which included additional steroid injections, platelet-rich plasma (PRP) injections or need for reoperation at a minimum of 12 months post procedure. Overall survival rate for ultrasonic percutaneous tendinopathy was 94% (47/50). Three patients required post-operative adjunct procedures, two received steroid injections and one required PRP injection. Mean VAS score improved from 8.1 to 2.8 in the no failure group vs 7.9 to 2.7 in the failure group. Mean postoperative Mayo Elbow score and Q-DASH score was 89 (range 60 to 100) and 12.7 (range 2.3 to 61.4), respectively. 84 percent of patients were either very satisfied (N=31) or satisfied (N=11) with their procedure. This three year study demonstrates that ultrasonic percutaneous tenotomy appears to be a safe and efficacious therapeutic option with a high survival rate for patients with recalcitrant lateral elbow tendinopathy.

Published: March 2023

: Ilizarov fixator for open tibia fractures permits axial micro mobility at fracture site to encourage bone regrowth. Literature search revealed dearth of studies from Indian centres which have evaluated its utility in open tibia fractures. : This was an observational prospective study conducted by Department of Orthopaedics at VVPF Medical College, Ahmednagar in Maharashtra, between July 2021 to June 2022. All patients who had open tibia fractures and managed by Ilizarov ring fixator were included. Duration of treatment with fixator was evaluated, along with range of motion at knee and ankle, union status and complications.: 30 patients were enrolled, majority being males (n=22, 73.33%). Most patients suffered from fractures of right side (n=21, 70%) confined to metaphyseal region (n=16, 53.33%). Commonest mode of injury was road traffic accidents (n=26, 86.67%). Based on Gustilo-Anderson classification, majority cases were grade IIIA (n=16, 53.33%). 23 cases (76.67%) were managed initially with external fixators, while 7 cases were directly managed with Ilizarov ring fixator. Most cases (n=15, 50%) received definitive fixation on day-3 of injury. Commonest complication noted was pin site infection (n=11, 36.67%) and delayed union (n=4, 13.33%). Knee stiffness at 30was noted in 3 cases, corrected by physiotherapy. All patients attained fracture union, with the earliest evidence of radiological union observed after 2 months of surgery. : As it allows for early full weight bearing mobilisation, has higher union rates and lesser incidences of malunion, use of Ilizarov external fixator maintains its importance in the management of open tibial fractures.
Terrible than terrible triad of elbow

Published: March 2023

The brachial artery is rarely injured in closed posterior dislocation, despite the anatomical proximity.Most cases of brachial artery injury after dislocation of the elbow are associated with fracture. The neurovascular examination that comprises checking for the distal pulse is mandatory, and the absence of the same is considered a warning sign. Investigations like doppler and arteriography should be done to prevent potential complications. Our study is about a patient with closed posterior dislocation with vascular insufficiency in the left ulnar and Radial artery due to following self-fall from a 2-wheeler. We treated her with Tissue reconstruction on the medial and lateral sides, including UCL and Common Flexor Origin and repaired LCL and Common extensor origin with Thrombectomy. At six months follow-up, no complications of vascular injury were noted.
Single dorsal incision approach for plate fixation of radius ulna midshaft fracture; interesting case report

Published: March 2023

Radius and ulna shaft fractures, also known as both bone forearm fractures, are common fractures caused due to direct or indirect trauma. Open reduction and internal fixation with plating by two separate incisions is a standard and widely accepted mode of fixation. We report a case where we approached the fracture with a single dorsal incision. An eighty years old female had fractures of both radius and ulna shaft with Gustilo Anderson type two open injury. We managed the patient with single-stage debridement, open reduction, and dynamic compression plate (DCP) fixation of both bones with a single dorsal curvilinear incision and followed up postoperatively for one year. At the end of the last follow-up, the patient had no pain with a full range of movement. There were no wound-related issues. Radiologically complete union occurred without complications mentioned in the literature, such as synostosis.: We found that under specific circumstances such as open injury where two separate incisions for radius and ulna are inappropriate, a single dorsal curvilinear incision for radius and Ulna midshaft fractures is a safe and effective alternative method.

Published: March 2023

The paper presents the results of a study of the regularities of the formation of granulometric composition, structure and properties of modifying ligatures with a high content of alloying component for the production of chrome bronzes. The kinetics of changes in the physico‑mechanical properties of granular compositions depending on the temperature in the grinding chamber and the ratio of the volume of working bodies to the volume of the charge has been studied. The results of the topography of granules and their structure are presented, showing that the granules obtained according to the optimal mode of mechanical fusion are dense bodies with microinclusions of chromium, the maximum size of which does not exceed 15–20 microns.Based on the results of thermodynamic modeling, thermodynamically justified refractory compounds synthesized in the process of obtaining a ligature have been established, which should effectively perform the role of modifiers of the first kind, ensuring the production of bronzes with a sub‑/microcrystalline type of base structure.The processes of compacting mechanically fused compositions were optimized and the influence of the main technological factors – the heating temperature of cold‑pressed briquettes and the extraction coefficient during hot pressing on the physical and mechanical properties of compact materials was investigated. The results of studying the structure and properties of the most promising Cu – 20 %Cr composition are presented, which make it possible to identify its microcrystalline type, which persists after prolonged high‑temperature exposure during the processing of the granular composition into a semi‑finished product, and to conclude about the dispersed nature of its hardening, which additionally confi ms the data of thermodynamic modeling on the possibility of mechanical synthesis of nanocrystals of refractory compounds to perform the role of modifiers.According to the results of the research, a comparative analysis of the properties of the developed ligature and beryllium bronze was performed, establishing the possibility of its use as an independent material for electrical purposes.
Detailed Geoseismic Structure of the Riphean Deposits in Buolkalakh–Lena Area Based on Deep Drilling and Seismic Exploration Data

Published: March 2023

Abstract
—The work considered an integrated approach to the study of deep-lying Riphean strata of the Buolkalakh–Lena region, which have certain prospects in terms of oil and gas potential. The method of revision and synthesis of acoustic and density logs is described in detail using the example of wells drilled in 80–90 for the purpose of correct reference to seismic sections. It has been shown that the Khaipakh, Debengdin, Arymas, Kyutingdinsky, and Sygynakhtakh formations of the Early and Middle Riphean eras overlook the pre-Permian surface in the middle part of the Lena–Anabar trough. The region also developed older Riphean deposits that are not exposed on the Olenek uplift and are not studied by deep drilling. The prospects for the oil and gas content of Riphean strata in the region are mainly associated with carbonate reservoirs formed in the top of the Riphean sequence and cropping out on the pre-Permian erosive surface, the most promising rocks are those constituting large carbonate platforms that were partially eroded and subjected to processes of hypergenesis and karst formation.

Correlating Sour Gas Testing with Successful Field Operations of High Strength Quenched and Tempered Coiled Tubing
Authors: Elliott Kevin , Davis Scott , Rentas Chris , Hayworth Jason , Woitas Tyler , Meadows Erica 
Published: March 2023

Abstract
Inhibition is considered critical to successful operations using high strength quenched and tempered coiled tubing in sour environments. Prior laboratory test results did not correlate well with initial field successes in Western Canada. The objective of this paper is to provide further testing that more closely matches real world applications and to provide additional field results from Western Canada.
Similar to prior work in Elliott et al (2022), the overall approach to this paper is twofold. The first part focuses on C-ring testing of quenched and tempered tubing to provide confidence, coiled tubing will not fail due to sulfide stress cracking (SSC) when properly inhibited. Testing was performed with a limited exposure time to account for the short window for CT operations and a reasonable inhibition effectiveness period. The second portion of the paper discusses best practices for coiled tubing operations in sour wells.
Laboratory C-Ring test results will be provided showing the effectiveness of the inhibition program as well as discussing the possible outcomes of utilizing coiled tubing in sour wells without inhibition based on the tests performed without inhibition. Discussion of the laboratory results will also describe the lessons learned in test plan development with respect to inhibitor effectiveness windows.
Following the practical best practices for sour well CT operations, the paper will also discuss field history of quench and tempered coiled tubing building on the initial trials reported in Elliott et al (2022). The paper will conclude with a qualification for each grade of quenched and tempered coiled tubing when used with inhibition for sour operations.
This paper expands upon the learnings of Elliott et al (2022) with testing program results that matches the field history of effective inhibition systems for high strength quenched and tempered coiled tubing in sour wells. This publication also explores the effects of sour exposure without the aid of inhibition, which serves to document the risks of forgoing inhibition in sour operations.
