Authors: Naumov Denis G. , Tkach Sergey G. , Ladygin Anton A. , Shchelkunov Mikhail M. , Karpushin Andrey A.
Published: February 2023

Background. Deep surgical site infection (DSSI) is one of the most severe complications in spinal surgery. The timing and nature of DSSI are the determining criteria in the choice of treatment tactics. The uniqueness of the clinical observation is the combination of early DSSI, epidural abscess and angular kyphotic deformity formed after a course of conservative antibacterial therapy in a patient who underwent surgery for degenerative-dystrophic disease of the cervical spine. Correction of angular kyphosis, removal of fractured vertebrae, interbody implants and three-column cervical reconstruction were performed in one surgical session.
Case presentation. A 57-year-old patient was admitted to the clinic after staged surgical interventions on the cervical spine for multilevel degenerative stenosis of the spinal canal. The primary surgical interventions were complicated by DSSI in the early period after the second surgery with formation of angular kyphosis of the cervical spine. The patient underwent revision one-stage reconstructive intervention to correct the deformity, decompress the spinal canal, and three-column reconstruction of C3-7 segments. Long-term follow-up showed persistent reduction of pain syndrome, improved quality of life and absence of recurrence of DSSI.
Conclusion. The presented case illustrates the possibilities of one-stage revision three-column cervical spine reconstruction for correction of sagittal profile, decompression of intracanal neural structures and ensuring stability of operated segments. Use of DSSI treatment algorithms based on Prinz V. and Vajkoczy P. classification contributes to the selection of the optimal tactics of patient management.
A Source Model for Earthquakes near the Nucleation Dimension
Authors: Cattania Camilla
Published: February 2023

Earthquake self-similarity is a controversial topic, both observationally and theoretically. Theory predicts a finite nucleation dimension, implying a break of self-similarity below a certain magnitude. Although observations of non-self-similar earthquake behavior have been reported, their interpretation is challenging due to trade-offs between source and path effects and assumptions on the underlying source model. Here, I introduce a source model for earthquake nucleation and quantify the resulting scaling relations between source properties (far-field pulse duration, seismic moment, stress drop). I derive an equation of motion based on fracture mechanics for a circular rupture obeying rate–state friction and a simpler model with constant stress drop and fracture energy. The latter provides a good approximation to the rate–state model and leads to analytical expressions for far-field displacement pulses and spectra. The onset of ground motion is characterized by exponential growth with characteristic timescale t0=R0/vf, with R0 the nucleation dimension and vf a limit rupture velocity. Therefore, normalized displacements have a constant duration, proportional to the nucleation length rather than the source dimension. For ray paths normal to the fault, the exponential growth results in a Boatwright spectrum with n = 1, γ=2 and corner frequency ωc=1/t0. For other orientations, the spectrum has an additional sinc(·) term with a corner frequency related to the travel-time delay across the asperity. Seismic moments scale as M0∼R(R−R0)R0, in which R is the size of asperity, becoming vanishingly small as R→R0. Therefore, stress drops estimated from M0 and fc are smaller than the nominal stress drop, and they increase with magnitude up to a constant value, consistent with several seismological studies. The constant earthquake duration is also in agreement with reported microseismicity: for 0<Mw<2 events studied by Lin et al. (2016) in Taiwan, the observed durations imply a nucleation length between 45 and 80 m.

Published: February 2023

OBJECTIVE: To assess the ability of hip and lumbopelvic neuromuscular control, endurance hip range of motion tests to predict transient low back pain development during 2 hours of prolonged standing in physical therapy students without a history of low back pain. DESIGN: Observational prospective study METHODS: Seventy-two physical therapy students with no history of back pain completed nine tests designed to assess hip and lumbopelvic neuromuscular control. They completed a 2-hour prolonged standing test on a second day during which the development of any low back pain was assessed using a 10 cm visual analog scale (VAS). Participants were classified as transient pain developers (PD) if they reported a [greater than or equal to]10mm increase on the VAS for low back pain. RESULTS: Thirty-seven and a half percent of students developed transient low back pain during the standing test. A cluster of three positive tests (self-rated active hip abduction, total hip passive internal rotation > 81.6 degrees, and non-dominant single leg squat > 5) demonstrated an increased probability (94.9%) of identifying PDs. Negative outcomes on the same three tests decreased the probability of developing transient back pain to 10.7%. Overall, the classification accuracy for the three-test model was 72.2%. The sensitivity for the model was 63% and specificity 77.8%. CONCLUSION: A 3-test cluster of hip and lumbopelvic neuromuscular control tests and hip internal rotation range of motion is an effective screening tool to identify physical therapy students who may develop transient LBP during 2 hours of prolonged standing.

Investigating the Plasmodium falciparum Mitochondrial Proteome for Functional Analysis of Conserved Essential Proteins
Authors:   , Lamb Ian  Michael , Vaidya Akhil B.
Published: February 2023

Mitochondrial functions are essential throughout the life cycle of malaria parasites and are validated as targets of antimalarial drugs such as atovaquone. Using a mitochondrially targeted proximity biotinylation approach, here, we explore the possibility that identification of novel, conserved, and essential proteins encoding mitochondrial functions may provide additional targets for the discovery of antimalarial drugs in P. falciparum. To initiate this investigation, we generated parasites that express a protein where the Hsp60 leader sequence (for mitochondrial targeting) is fused to the promiscuous biotin ligase TurboID from an ectopic locus. Initial experiments suggested inefficient targeting to the mitochondrion, as many cytosolic proteins were identified in the mass spectrometry analysis, presumably due to labeling by Hsp60L-TurboID proteins in transit to the mitochondrion. To overcome this challenge, we employed hypotonic lysis and centrifugation to fractionate parasite pellets into "soluble" and "membrane" fractions after labeling. After three biological replicates of this experiment and subsequent mass spectrometry analysis, we identified 121 proteins that we considered to be "putative mitochondrial" proteins. Of these, 26 were annotated as conserved Plasmodium proteins of unknown function. We characterized five of these 122 for their sub-cellular localization and found that four were localized to the mitochondrion. Of these, PF3D7_0707400 attracted our attention as a candidate for phenotypic characterization. This protein is abundantly expressed and is an ortholog of mammalian ATAD3A (ATPase family AAA+ domain-containing protein 3), a mitochondrial membrane localized protein. In mammals, ATAD3A spans the matrix, the inner and outer mitochondrial membranes, and communicates with the endoplasmic reticulum, playing a central role in mitochondrial biogenesis. ATAD3A orthologues are conserved in all apicomplexans, including Cryptosporidium, suggesting it to have a critical role in mitochondrial physiology of all of these parasites. To initiate its characterization in malaria parasites, we generated parasites in which this protein was endogenously tagged and subjected to conditional expression. These parasites grew normally in the presence of aTc but failed to thrive in the absence of aTc within 72 hours. Mitochondrial membrane potential in PfATAD3A knockdown parasites was collapsed by 48 hours. Native gel electrophoresis suggested PfATAD3A to be a part of a complex estimated to be >5 million Dalton. Characterization of this complex will likely reveal hitherto unknown essential features of mitochondrial physiology in malaria parasites.

Published: February 2023

Additive manufacturing technologies offer a multitude of medical applications due to the advances in the development of the materials used to reproduce customized model products. The main problem with these technologies is obtaining the correct cell viability values, and it is where three-dimensional (3D) bioprinting emerges as a very interesting tool that should be studied extensively, as it has significant disadvantages with respect to printability. In this work, the comparison of 3D bioprinting technology in hydrogels and thermoplastics for the development of biomimetic parts is proposed. To this end, the study of the printability of different materials widely used in the literature is proposed, to subsequently test and analyze the parameters that indicate whether these materials could be used to obtain a biomimetic structure with structural guarantees. In order to analyze the materials studied, different tools have been designed to facilitate the quantitative characterization of their printability using 3D printing. For this purpose, different structures have been developed and a characterization methodology has been followed to quantify the printability value of each material in each test to subsequently discard the materials that do not obtain a minimum value in the result. After the study, it was found that only gelatin methacryloyl (GelMA) 5% could generate biomimetic structures faithful to the designed 3D model. Furthermore, by comparing the printing results of the different materials used in 3D bioprinting and consequently establishing the approach of different strategies, it is shown that hydrogels need to be further developed to match the results achieved by thermoplastic materials used for bioprinting.
Design and fused deposition modeling of triply periodic minimal surface scaffolds with channels and hydrogel for breast reconstruction
Authors: Zhu Xiaolong , Chen Feng , Cao Hong , Li Ling , He Ning , Han Xiaoxiao
Published: February 2023

3D-printed scaffolds that forge a new path for regenerative medicine are widely used in breast reconstruction due to their personalized shape and adjustable mechanical properties. However, the elastic modulus of present breast scaffolds is significantly higher than that of native breast tissue, leading to insufficient stimulation for cell differentiation and tissue formation. In addition, the lack of a tissue-like environment results in breast scaffolds being difficult to promote cell growth. This paper presents a geometrically new scaffold, featuring a triply periodic minimal surface (TPMS) that ensures structural stability and multiple parallel channels that can modulate elastic modulus as required. The geometrical parameters for TPMS and parallel channels were optimized to obtain ideal elastic modulus and permeability through numerical simulations. The topologically optimized scaffold integrated with two types of structures was then fabricated using fused deposition modeling. Finally, the poly (ethylene glycol) diacrylate/gelatin methacrylate hydrogel loaded with human adipose-derived stem cells was incorporated into the scaffold by perfusion and ultraviolet curing for improvement of the cell growth environment. Compressive experiments were also performed to verify the mechanical performance of the scaffold, demonstrating high structural stability, appropriate tissue-like elastic modulus (0.2 – 0.83 MPa), and rebound capability (80% of the original height). In addition, the scaffold exhibited a wide energy absorption window, offering reliable load buffering capability. The biocompatibility was also confirmed by cell live/dead staining assay.

Published: February 2023

The purpose of this study was to examine the associations between meeting recommendations for 24-hour movement behaviors,
parental academic support, and student academic achievement in a sample of Alaskan adolescents. Data were obtained from
the 2019 Alaska Youth Risk Behavior Survey (YRBS; N = 1,897; mean age = 15.8 ± 1.3 years old). The associations between
meeting recommendations for the 24-hour movement behaviors of physical activity, screen use, and sleep with high academic
achievement (mostly A’s and B’s) were examined using weighted multivariable logistic regressions. Subpopulation analyses
determined if associations differed by levels of parental academic support. Approximately 18.8% of the sample met PA
recommendations, 70% met screen use recommendations, and 24.6% met sleep recommendations. Parents providing everyday
academic support are associated with higher odds of an adolescent reporting mostly A’s and B’s (OR = 2.03, p < .001). Meeting
screen use recommendations associated with high academic achievement in adolescents with less than every day pa-rental academic
support (OR = 1.87, p = .001) and meeting sleep recommendations associated with high academic achievement in adolescents with
less than every day (OR = 2.20, p = .005) and every day (OR = 1.77, p = .038) parental academic support. Meeting PA recommendations
did not associate with high academic achievement. These findings elucidate the complexity of these interrelationships but warrant
additional longitudinal investigation.

Objectives: To explore the expression levels of nuclear factor kappa B (NF-κB) and inhibitor of nuclear factor kappa B kinase (IKKβ) in epithelial ovarian cancer and the correlation analysis with multi-drug resistance-related genes 1 (MDR1), topoisomerase II (TOPOII) and nucleotide excision repair cross complementary group 1 (ERCC1). Methods: Immunohistochemical methods were used to detect the expression levels of NF-κB and IKKβ in epithelial ovarian cancer group (50 cases), ovarian benign tumor group (30 cases), and normal ovary group (10 cases). The expression levels of NF-κB, IKKβ, MDR1, TOPOII and ERCC1 messenger ribonucleic acid (mRNA) and protein were analyzed using real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot. Student’s t-test and one-way ANOVA were used for comparison of numerical data. Pearson’s chi-squared and Fisher’s exact tests were carried out for analysis of non-numerical data. Results: The levels of NF-κB, IKKβ, MDR1 and ERCC1 mRNA and protein were increased (P<0.05), and the expression levels of TOPOII were decreased (P<0.05) in the epithelial ovarian cancer group compared to the normal ovary and benign ovarian tumor groups. The expression of NF-κB and IKKβ in epithelial ovarian cancer was significantly increased in patients with higher tumor stage, lower differentiation and presence of lymph node metastasis and positively correlated with MDR1 expression. NF-κB and IKKβ were negatively correlated with the expression of TOPOII and antagonized each other with TOPOII. Conclusions: The expression of NF-κB and IKKβ was positively correlated with the expression of MDR1, and negatively correlated with the expression of TOPOII. The correlation of NF-κB, IKKβ and resistance related genes, including MDR1, TOPOII, ERCC1, can predict the resistance of chemotherapy individuals to chemotherapy.
COVID-19, firm performance, and the value relevance of earnings
Authors: Ali Ijaz
Published: February 2023

In the wake of the COVID-19 crisis, there has been a growing interest in investigating how stock markets behave during times of uncertainty and crisis. This is because it has been shown that stock prices seem to disconnect from fundamentals during moments of extreme uncertainty. Using earnings and returns data from publicly traded corporations for the twelve months beginning January 1, 2020, we assessed the performance of major industrial sectors during COVID-19. We also investigated the concurrent earnings/returns relation to discover whether earnings changes convey useful information during times of high uncertainty. Following prior literature along similar lines, we used firm-level earnings and returns data and estimated cross-sectional regressions to examine the earnings/returns relation. We found considerable variation in the earnings and returns data across and within the industrial sectors. Our results mostly showed a positive relationship between accounting income and concurrent stock returns, implying that accounting earnings numbers were value relevant during the pandemic. Positive earnings news (earnings increases) seemed to generate a greater market response than negative earnings news (earnings drops), leading to a shift in the overall stock market's outlook from negative to positive in the second half of 2020. These findings will help the decision-making of investors, creditors, policymakers, financial analysts, and other stakeholder groups.

Abordaré la crítica de Axel Honneth a la primera Escuela de Frankfurt y su aparente omisión de Herbert Marcuse. Defenderé a Marcuse contra algunas de las críticas hechas por Honneth a la teoría crítica temprana de la Escuela de Frankfurt. Luego argumentaré que Marcuse siempre estuvo en busca de una subjetividad radical, incluso cuando advirtió contra los mecanismos unidimensionales en curso de producción de sujetos. Finalmente, mostraré que Honneth también construye su proyecto en torno a la búsqueda de una subjetividad radical, pero aborda el problema a través de una teoría de la intersubjetividad que complementa el proyecto de Marcuse.

Published: February 2023

The aim. Today we are witnessing the actualization of research on plant sources for the pharmaceutical and food industries. It is caused by a significant increase in demand for these types of resources. Therefore, a variety of case studies aimed at identifying the characteristics of plant resources, are becoming more actual too. In accordance with this need, the present work aims to identify a relationship between the content of flavonoids in the raw material of such important source of plant raw material as Epilobium angustifolium and soil and climatic conditions and group of raw materials.

Methods. At the first stage of this work were applied cartographic, geographical methods and methods of geobotanical description of phytocenoses to determine the most suitable locations for the purposes of the study. At the second stage were applied the method of spectrophotometry to determine the amount of flavonoids in terms of rutin and the method of correlation analysis.

Results. As a result of the application of these methods were obtained data on the content of flavonoids in the Epilobium angustifolium raw materials, collected in various soil and climatic conditions, as well as in various morphological groups of raw materials. These data were compared by the method of correlation analysis and after that a positive correlation between the content of flavonoids in the leaves and inflorescences of Epilobium angustifolium was found.

Conclusion. It was determined, that the content of flavonoids fluctuation, depending on the Epilobium angustifolium place of growth, was 2.05% in the leaves and 2.5% in the inflorescences of this plant. An average positive correlation of 0.65 was found between the content of flavonoids in the leaf and inflorescences of Epilobium angustifolium. However, the correlation between the content of flavonoids and the latitude of Epilobium angustifolium growth wasn’t identified.
Ecological testing of varieties beetroot selection of FSBSI FSVC
Authors: Vetrova S. A. , Stepanov V. A. , Zayachkovsky V. A.
Published: February 2023

Relevance. The value of table beetroot as an indispensable vegetable crop in a rational human diet is beyond doubt. It is possible to fill the shortage of production of this crop in the Russian Federation by increasing yields, which is facilitated by a number of factors. It is believed that the yield depends more on the variety, but the role of the medium in identifying varietal characteristics is also of great importance. In this regard, the varieties and hybrids recommended for production, along with high potential productivity, should be characterized by a wide range of adaptive properties (environmental resistance) to the stressful effects of environmental conditions. One of the effective methods to determine the adaptability of varieties to the conditions of a particular region is their simultaneous assessment in a number of geographically remote locations, which allows expanding the range of their use.

Materials and methods. Research work on the environmental testing of six varieties of beetroot was carried out in 2020 according to generally accepted methods on the basis of the branches of the FSBSI Federal Scientific Vegetable Center. As a standard, the Bordo 237 variety was used - recommended for cultivation in all regions of the Russian Federation. Ecological assessment of the environment as a background for selection and assessment of the adaptive ability of varieties was carried out according to the methodology of A.V. Kilchevsky and L.V. Khotyleva.

Results. According to the totality of all parameters, the most adaptive for cultivation in different regions of the Russian Federation, according to the combination of yield and marketability, it is possible to recommend the varieties of beetroot Karina and Bordo 237; according to the mass of commercial root crops - Karina and Gazpadynya. The varieties characterized by the greatest responsiveness to the improvement of growing conditions were: Lyubava, Gaspadynya, Dobrynya. The most informative background for identifying the potential productivity of varieties is the environment on the Biryuchekutsk station, on the ecological stability of the complex of signs – the Voronezh station. The most typical environments for growing beets on the grounds of "yield" and "marketability" are the conditions of Biryuchekutsk station, by weight of commercial root crop – Voronezh station.
The dynamics of wild populations of Henosepilachna vigintioctomaculata Motch. (Coleoptera:Coccinellidae) in Primorsky Krai

Published: February 2023

Relevance. Population dynamics (population waves) is an intrinsic quality of population systems. These fluctuations can be induced by various factors, e.g. environmental conditions and resource availability, elements of a food chain from the same or a higher level (competitors, parasites, predators), and diseases. Few researchers have addressed the issue of the population dynamics of Henosepilachna vigintioctomaculata in the Russian Far East. This paper investigates the reasons why the potato ladybird beetle became a pest of introduced cultivated plants.

Materials and methods. To collect data on imagines, all research sites were examined at intervals of eight days during the entire period of the study. The examination of the research sites was conducted within one day. All the imagines taken from host plants were marked at the first encounter by puncturing their elytra with a sewing needle (0.4 mm in diameter) according to Hirano. The next generation of beetles was marked with nail polish (in two-three days after emergence) to avoid traumatizing the insects. At the second encounter, these beetles were also marked by puncturing their elytra with a needle. The methods implemented did not have an adverse effect on the survivability of the studied imagines. The beetles were released to the same plants where they had been taken from. The research data were analyzed by Jolly’s method.

Results. Overwintered imagines appeared in the fields and began ovipositing at the end of May. The first generation of imagines appeared at the end of June – the begging of July. The second generation of imagines could be observed at the end of July – the beginning of August. A part of the imagines migrated to overwintering sites without ovipositing approximately at the end of August. The overwintered beetles were observed to emerge on the Mongolian oak Q uercus mongolica, the greater celandine Chelidonium majus, and the bird cherry Prunus padus. A typical primary biotope of the potato ladybird beetle was a potato field at the stage of vegetative growth (5-7 leaves) surrounded by the couch grass Elymus repens, the common dandelion Taraxacum officinale, and the perennial sow-thistle Sonchus arvensis. Marking the overwintered and new generations of imagines showed that the presence of the potato ladybird beetle in an ecosystem depended on agricultural and agrometeorological conditions.

Authors: Greif Boris , Hojski Aljaž , Crnjac Anton
Published: February 2023

Purpose: We evaluated our one– year experience in the intraoperative measurement of parathyroid hormone (IOPTH) in parathyroid adenoma surgery. We also compared surgical outcome after minimally invasive parathyroidectomy (MIP) and conventional neck exploration (CNE).

Methods: Between April 2011 and April 2012, eight consecutive patients with primary hyperparathyroidism (PHP) underwent parathyroidectomy with IOPTH in our institution. Parathyroidectomy was defined as successful when a >50% decrease of IOPTH was observed 10 minutes after resection of the abnormal gland. The second criterion for success was a six month period of postoperative normocalcaemia.

Results: We performed four MIPs, two unilateral neck explorations, and two bilateral neck explorations, resulting in a total of seven solitary and one double adenomas. IOPTH level decrease expectations were met in all cases. The average length of surgery for MIP was 31 minutes, and 69 minutes for CNE. All patients were eucalcaemic with normal PTH levels during the 6 month follow–up period. Three patients had postoperative hypocalcaemia after CNE and there were no recurrences 6 months postoperatively.

Conclusion: The review of our series of eight consecutive patients with PHP showed a 100% cure rate after employing IOPTH measurement in both surgical approaches. The advantages of MIP are: shorter operating time, better cosmetic results, and a lower incidence of hypocalcaemia.
Acute syphilitic posterior placoid chorioretinitis: a case report
Authors: Skitek Petra
Published: February 2023

Purpose: To present a case of acute syphilitic posterior placoid chorioretinitis (ASPPC), one of the possible ocular manifestations of syphilis, and alert clinicians to the reemergence of syphilis worldwide.

Methods: Clinical findings, fluorescein angiography, indocyanine green angiography, autofluorescence imaging, time domain optical coherence tomography features, and management of the patient are presented.

Results: A 39–year–old male presented as an otherwise healthy man with a 3–day history of blurred vision in his right eye. Clinical examination revealed signs of posterior uveitis. Clinical features and additional imaging findings were consistent with the descripton of ASPPC. Syphilis was confirmed with a positive serological test for syphilis. Additional human immunodeficiency virus (HIV) testing was intended and the patient only then disclosed his medical history of being HIV positive and receiving antiretroviral therapy. Cerebrospinal fluid examination revealed neurosyphilis. He was treated with a 2– week course of intravenous penicillin and his visual acuity recovered fully.

Conclusions: Ocular findings may be the presenting feature of syphilis. Physicians' awareness of the variety of clinical presentations of syphilis is important for prompt recognition and early management of this curable disease, which can cause substantial morbidity and increased mortality if left untreated.
Predatory journals / Plenilske revije
Authors: Pahor Dušica
Published: February 2023

The name “predatory open access” was first used by Jeffrey Beall, researcher and librarian at the University of Colorado at Denver, to describe journals for profits and not for the promotion of scientific data. In 2010, he published the first list of predatory publishers. Beall's list includes potential, possible, or probable predatory scholarly open-access publishers. Predatory practice includes not only journals, but also monographs, conferences and conference proceedings (1).

Man reaps the reward when he follows his deepest intention. As graduates, we have been growing and developing over the years with the motivation to reach a day such as this one. We have dreamed that, after years of putting much effort and time into our studies, a door to a new world will be opened to us, so we shall be able to help people on their path to health using the knowledge and skills that we have acquired. Therefore, we are finally here today in front of the door and we are waiting to open it slowly before crossing over the threshold at doctors' surgeries, health centers, hospitals and clinics. Each one of us, in our own way, is following our dreams.
Atherosclerosis, epigenetic modifications, and arterial stiffness
Authors: Piko Nejc , Ekart Robert , Bevc Sebastjan , Hojs Radovan
Published: February 2023

Atherosclerosis is a chronic, inflammatory vascular disease, characterized by progressive plaque build-up in the vessel wall, leading to tissue ischemia. It is the most common cause of cardiovascular diseases and is a major epidemiologic concern in modern society. The pathophysiology of atherosclerosis includes two main events: endothelial injury and vessel wall inflammation. Recent findings indicate that the pathogenesis of atherosclerosis involves dynamic changes in epigenetic modifications and gene expression in a cell type- and stage-specific manner. Epigenetics is the study of gene expression and involves phenotypical variations without genotypic changes. Three major epigenetic mechanisms participate in atherosclerosis: DNA methylation, posttranslational modifications of histones, and non-coding RNA molecules (long non-coding RNA molecules [lncRNAs] and microRNA molecules [miRNAs]). The field of epigenetics has opened up new diagnostic and therapeutic options. Arterial stiffness is increasingly recognized as a surrogate endpoint for cardiovascular disease. Pulse wave analysis (PWA) and pulse wave velocity (PWV), determined by applanation tonometry, provide essential information on central aortic stiffness. PWA and PWV are strongly correlated with atherosclerosis and can be used as a tool for assessing cardiovascular status and the risk of mortality and morbidity in patients with coronary disease, cerebrovascular disease, diabetes, arterial hypertension, and kidney disease.
Bilateral Kienböck’s disease with bilateral negative ulnar variance: a case report
Authors: Sekej Marjan , Rupreht Mitja
Published: February 2023

Purpose: Kienböck’s disease usually occurs unilaterally on dominant hands. As such, bilateral avascular necrosis of the lunate, in concurrence with bilateral negative ulnar variance (NUV), is a very rarely described condition.

Case report: The case of a patient diagnosed with bilateral avascular necrosis of the lunate is presented. Plain film and magnetic resonance imaging confirmed bilateral NUV was also present.

Conclusions: Although the relationship between Kienböck’s disease and NUV remains unclear, the bilateral concurrent appearance of both might instigate a discussion of the possible etiology of avascular lunate necrosis.
Early diagnosis of giant cell arteritis - the basis of good outcome
Authors: Holc Iztok
Published: February 2023

Purpose: If untreated, giant cell arteritis can lead to blindness and stroke. The study objectives were to assess diagnostic procedures and treatment in early interventional clinic in University Clinical Centre Maribor in patients with temporal arteritis.

Methods: Retrospective study (from 2012 to 2017) of patients diagnosed with temporal arteritis. We assessed epidemiological data, delay of diagnosis, and diagnostic procedures. Results were assessed with statistical methods (SPSS 22.0).

Main goal: The main goal was to determinate the delay in days between symptom onset and admission to the interventional rheumatology clinic and to assess the causes of delay.

Results: Fifty-three GCA (66 % female) patients with mean age 76.25 (from 63–89 years) years were included. Mean time duration of symptoms before admission to our early interventional clinic was 33.74 (0–180) days. The diagnostic procedure was completed in mean time of 2.04 days from the presentation at our interventional rheumatology clinic. The median time to the temporal artery biopsy (TAB) performed in 52 /53 patients was 2 days, with the median 2 days to the preliminary histological results from admission. TAB was positive in 43 (81.1%) of cases. The median time from admittance to colour Doppler sonography (CDS) of aortic arch branches was 2 days and it was positive in all 19 (35.8%) performed cases. 16 (30.2%) patients had polymyalgia rheumatica, 35 (66%) patients had visual disturbances, permanent one eye blindness occurred in 12 (22.64%) patients, and 2 (2.8%) patients experienced permanent blindness on both eyes. Seventeen patients (32.1%) were initially treated with intravenous methylprednisolone pulse. The mean initial dose of oral methylprednisolone was 45.55 (± 15.54) mg. All patients received low dose Aspirin.

Conclusion: Early diagnosis and treatment of giant cell arteritis are very important as miss- or non-diagnosed GCA can lead to permanent blindness of the patient. With better education and public awareness, better access and better professional education of primary care physicians, and early admission to secondary interventional clinics we might spare these patients from the devastating consequences of the GCA.
