Lichen planus and chronic active hepatitis. A retrospective survey
Authors: Rebora A , Rongioletti F.
Published: August 2023

In a retrospective survey 95 in-patients with non erosive lichen planus (LP) were summoned to be investigated by means of routine liver tests. 44 patients responded. Remarkable abnormalities of liver tests were found in 6 patients who were further studied for antibodies to smooth muscle and mitochondria and submitted to liver biopsy. Histological diagnosis revealed chronic active hepatitis (CAH) in 5 cases (11.3%). Such an impressive prevalence and the histologic and immunologic similarities between the two diseases support the view that the association LP-CAH is not fortuitous and that both diseases may have the same autoimmune pathogenesis. Accordingly LP may be regarded as a major risk factor for liver cirrhosis.
Familial discoid lupus erythematosus associated with heterozygous C4 deficiency
Authors: Voigtländer V , Bahmer F , Hauptmann G.
Published: August 2023

Low levels of the fourth component of complement (C4) were found functionally and immunochemically in two sisters (17 and 22 years of age) suffering both from discoid lupus erythematosus. C4-typing of the family revealed that the two sisters and the mother had only two, and the father three of the four genes coding for C4 expressed. All carried the null allele C4B*QO. This observation adds to the increasing evidence that not only complete but also partial genetic complement deficiencies may predispose to lupus erythematosus.

Hereditary palmoplantar keratoderma in the northernmost county of Sweden
Authors: Gamborg Nielsen P.
Published: August 2023

A papular and a diffuse variety of hereditary palmoplantar keratoderma (Unna Thost) are described. It was not possible to demonstrate any histopathological differences between the two varieties. Of the patients examined 36.2% were found to have dermatophytosis in addition to hereditary palmoplantar keratoderma. The hyperkeratosis was smooth and uniform in both varieties. When scaling and fissuring did occur they were signs of dermatophytosis and not part of the clinical picture. The examination of biopsies stained with H&E and PAS showed that dermatophytosis in patients with hereditary palmoplantar keratoderma, especially those with recurrent vesicular eruptions, gave rise to a histopathological picture which was, in some respects, similar to that of acute vesicular eczema.

Clinical manifestations of erythema chronicum migrans Afzelius in 161 patients. A comparison with Lyme disease
Authors: Asbrink E , Olsson I.
Published: August 2023

Clinical symptoms were studied in 161 consecutive patients with erythema chronicum migrans Afzelius and in a follow-up study signs of late manifestations were investigated. General symptoms such as headache, fever, myalgia and/or arthralgia were found in about half of the patients with a disease duration of less than or equal to 3 weeks. Three patients had coexisting lymphadenosis benigna cutis. Two untreated patients developed meningitis/meningoradiculitis and one untreated patient arthritis. The importance of a sufficient antibiotic therapy to prevent late manifestations is stressed. Although there are many similarities between erythema chronicum migrans Afzelius and Lyme disease, the results of the present study also point to differences. Multiple skin lesions, pronounced general symptoms, laboratory abnormalities and major symptoms from the joints were less common in patients with erythema chronicum migrans Afzelius than reported in patients with Lyme disease, but a prolonged course of the skin eruption was more common.

Authors: Smolle J.
Published: August 2023

In normal human epidermis HLA-DR-antigen is only present on Langerhans´ cells and the acrosyringeal epithelium. We investigated the distribution of HLA-DR-antigen in 78 specimens of various skin diseases by an immunoperoxidase method using a monoclonal anti-HLA-DR antibody. HLA-DR-antigen bearing keratinocytes were not only found in lichen planus and mycosis fungoides, as it has been referred previously, but were also observed in some cases of cutaneous B-cell lymphoma, pseudolymphoma, lupus erythematosus, parapsoriasis en plaque, bullous pemphigoid, drug reaction, contact dermatitis, actinic keratosis and verrucous carcinoma. Direct contact of lymphoid cells with keratinocytes was not necessary for Ia-antigen expression.
Class Formation in Post 2018 Ethiopia; A Commentary
Authors: M Tolera
Published: August 2023

This commentary aims to explore the dynamics of class formation in post-2018 Ethiopia, with a focus on the emergence of a new middle class, the opportunities and challenges it presents, and its implications for the country’s economic and social development. The study employs a qualitative approach, drawing on existing literature, policy documents, and interviews with experts in the field. The findings indicates that the emergence of a new middle class in post-2018 Ethiopia is a complex and multifaceted process, influenced by a range of political, economic, and social factors. While the growth of this class presents opportunities for economic growth and social mobility, it also exacerbates existing inequalities and poses challenges to social cohesion. The study concludes that a comprehensive and inclusive approach to economic and social development is necessary to address these challenges. This includes policies that address income inequality, promote regional unity, invest in education and job creation, and support vulnerable populations. The government must also engage in collaborative and inclusive policy- making to ensure that the benefits of economic growth are shared more equitably across society. Based on these findings, the study recommends that policymakers in Ethiopia take a holistic approach to class formation, recognizing the diverse and evolving nature of the country’s social and economic landscape. By doing so, they can promote greater stability and prosperity for all Ethiopians, and ensure that the benefits of economic growth are shared more equitably.

Authors: Paganini Claudia
Published: August 2023

A 68-year-old woman with chronic plaque psoriasis for 37 years was seen in June 2021. The patient was under secukinumab treatment and showed generalized exfoliative dermatitis with severe itch. Many authors reports that some biological drugs can induce chronic inflammatory diseases such as psoriasis and atopic dermatitis, especially anti-IL17 drugs. Consequently, we decided to stop secukinumab treatment and to start dupilumab. After six weeks of dupilumab treatment, guselkumab was added to manage the psoriatic disease. At one month of combinate therapy, the patient reported significant improvement of various parameters such as PASI, EASI, NRS itch, NRS sleep, and DLQI. Currently, the patient is receiving only treated with guselkumab 100 mg every 8 weeks, maintaining complete recovery from the disease.

Development of Radiological Models for Three-Dimensional Reconstruction of the Stomach as a Surgical Planning Method in Revisional Bariatric Surgery
Authors: Fernando Trebolle Jose
Published: August 2023

It has been shown that three-dimensional radiological reconstruction from CT scan images is very useful in the preoperative planning of complex cases using the patient's preoperative studies. It has been seen to have the most benefit in hepatobiliary and colorectal surgery. Different reconstruction means have been proposed, but all of them are considered validated to plan the critical steps of the intervention. This paper presents our 3D reconstruction model of post-bariatric surgery anatomy, to propose its applicability in revisional surgery. Anatomical models of three-dimensional stomach imaging and post-surgery anatomy have been developed. CT scan images are obtained with the Siemens Somatom Perspective 64equipment. Image recovery is in DICOM format and the processing to achieve three-dimensional reconstruction is done with the OsiriX computer program, performing a complete segmentation of the entire surface to be reconstructed, and a modification of image density. The obtaining of three-dimensional reconstruction images of post-bariatric surgery anatomy allows to develop models that can improve preoperative planning in revision surgery cases, but the risk-benefit of the radiation produced by the CT scan must be assessed to do it systematically

Published: August 2023

Good service can help the organization improve efficiency and effectiveness in operations. Optimal service can also improve the customer experience and provide added value to an organization that provides services. One of the services that can be optimized is the Merdeka Belajar Kampus Merdeka (MBKM) program which is a learning program organized by the Ministry of Education, Culture, Research, and Technology (Kemendikbudristek), especially MBKM services at the Institut Teknologi Telkom Purwokerto (ITTP). The problem is that the MBKM service at ITTP is not optimal due to inaccessibility to anyone and so many programs available. Thus, resulting in not optimal services provided. Therefore, this study aims to implement a Chatbot service in the MBKM program at ITTP. The method used in building a Chatbot service is the Deep Learning Long Short-Term Memory (LSTM) algorithm. LSTM is a type of artificial neural network architecture that matches text data. The results show an accuracy score of 100% and a loss of 0.121%. Meanwhile, the results of the further evaluation are in the form of average weights consisting of precision, recall, and F1-score, respectively of 100%, 100%, and 100%.

The fundamental relations of the quasi-static problem of thermoelasticity are written for a finite layered orthotropic cylindrical shell of an antisymmetric structure. Under convective heat transfer on the surfaces of this shell and under a linear dependence of temperature on the transverse coordinate, the basic system of equations for the integral characteristics of temperature is given. The method is proposed for solving the formulated problems of thermoelasticity and thermal conductivity, using the double finite integral Fourier transform with respect to the corresponding coordinates of the transformation and Laplace transform with respect to the time. The results of a numerical analysis of temperature, deflections, and stresses for the considered two-layer shell hinged at the edges under local heating by the initially specified temperature field are presented.

In this study, we propose a discrete time mathematical model (SEIQR) that describes the dynamics of monkeypox within a human population. The studied population is divided into five compartments: susceptible (S), exposed (E), infected (I), quarantined (Q), and recovered (R). Also, we propose an optimal strategy to fight against the spread of this epidemic. In this sense we use three controls which represent: 1) the awarness of vulnerable people through the media, civil society and education; 2) the quarantine of infected persons at home or, if required, in hospital; 3) encouraging of vaccination of susceptible persons. To characterize these optimal controls, we apply the Pontryagin's maximum principle. The optimality system is solved numerically using Matlab. Therefore, the obtained results confirm the effectiveness of the proposed optimization approach.

Stroke in Indonesia was the second leading cause of death and third cause of disability in the world. In Indonesia, the proportion of disability adjusted life-years (DALYs) contribution from stroke is around 9.7% and is the number one cause of disability. People with disabilities will have difficulty doing daily activities, especially communication. Therefore it is necessary to develop communication aids that can help stroke sufferers communicate daily by utilizing palm movements. In this study, two flex sensors were placed on the fingers. Communication aids for stroke sufferers function to detect four basic movements, namely: "I want to eat", "I want to drink", "I want to urinate/poop",and “rest”. The four sentences are also displayed on a display and also on the Smartphone. The detection of these four movements is obtained by bending the two fingers which are detected using a flex sensor placed on a glove. This tool is expected to be the development of communication aids for stroke sufferers.

We conducted a Specific Absorption Rate (SAR) study and measurements of wireless and mobile phone networks to evaluate the hazard of RF radiation limit. Our measurements have been carried out at different locations on the campus of Cihan University – Erbil. The RF strength level measurement of a base station on site was done by using spectrum analyzer with a dipole antenna and Electro Magnetic Field detector (EMF) application in the handsets for mobile networks, then comparing our measurements with the international slandered SAR’s levels.

The aim of this study was to provide data on the frequency of Top 7 Shiga toxin-producing Escherichia coli (STEC) and microbial population counts on processed beef from Argentinean Kosher cattle abattoirs authorized to export to Israel. A total of 480 samples (forequarters, primal cuts, trimmings) were taken and analyzed for Top 7 STEC detection and isolation and for mesophilic aerobic organism, coliform and E. coli enumeration. Differences in stx detection and microbial population counts on forequarter samples before and after salting were not statistically significant (P >0.05). All samples were negative for Top 7 STEC. Differences were significant for all microbial counts in primal cuts (P <0.001). Neck samples showed a higher level of contamination with the three groups of microorganisms than fore shank and brisket samples. The prevalence of stx was lower than that reported worldwide and in Argentinean export abattoirs. Salting did not significantly reduce the microbial load on forequarters.

OBJECTIVE

To investigate the incidence and patterns of gunshot wound trauma in patients that were presented to an urban level 1 veterinary trauma center before and after the start of the coronavirus disease of 2019 (COVID-19) pandemic.

ANIMALS

24 dogs and 1 cat.

METHODS

Medical records were retrospectively reviewed for patients presenting with gunshot wound injuries between March 2018 and February 2020 (prepandemic) and March 2020 and February 2022 (pandemic). The total number of patients presented to the hospital during those same time periods was also obtained. Patient data were collected including species, breed, age, sex, location of injury, trauma score (if available), surgical procedures performed, length of hospitalization, and case outcome.

RESULTS

In the prepandemic period, 9 patients were presented for gunshot wound injuries, whereas there were 16 patients evaluated for gunshot wound injuries during the pandemic period. The total number of gunshot wound cases increased by 77.8% in the pandemic period. The total number of hospital patient visits, however, decreased by 12.2% in the pandemic period as compared to the prepandemic period: 65,168 versus 74,262 patients, respectively. Injuries were predominantly localized to the extremities (55%) in the prepandemic period versus maxillofacial (56%) in the pandemic period.

CLINICAL RELEVANCE

There was an increased number of gunshot wound injuries in companion animals presenting to an urban level 1 veterinary trauma center during the COVID-19 pandemic. A shift in the predominant location of injury was also identified during the pandemic period. This study highlights the ramifications that societal dynamics can have on animal health and welfare.
Use of mesenchymal stem cells for tendon healing in veterinary and human medicine: getting to the “core” of the problem through a one health approach

Published: August 2023

The purpose of this manuscript, which is part of the Currents in One Health series, is to take a comparative approach to stem cell treatment for tendon injury and consider how the horse might inform treatment in other veterinary species and humans. There is increasing experimental and clinical evidence for the use of bone marrow–derived mesenchymal stem cells to treat tendon injuries in the horse. The same evidence does not currently exist for other species. This manuscript will review why the equine superficial digital flexor tendon core lesion might be considered optimal for stem cell delivery and stem cell interaction with the injury environment and will also introduce the concept of stem cell licensing for future evaluation. The companion Currents in One Health by Koch and Schnabel, AJVR, October 2023, addresses in detail what is known about stem cell licensing for the treatment of other diseases using rodent models and how this information can potentially be applied to tendon healing.
The Influence of Warming on Phosphorus Burial in Continental Margin Sediments

The marine phosphorus cycle plays a critical role in regulating rates of primary productivity and thus the size of the marine biosphere. Yet, the cumulative effects of temperature change—and warming, in particular—on marine phosphorus burial remain poorly understood. Here, we explore a benthic biogeochemical model that accounts for the compounded effect of temperature on the kinetics of key diagenetic reaction pathways, diffusion coefficients, seawater pH, dissolved O2 concentration and bioturbation, in order to provide a new predictive framework for understanding the temperature response associated with P burial in continental margin settings. We find that temperature has a direct and positive impact on marine phosphorus burial, as it directly increases the formation rate of key mineral P-removal pathways—foremost carbonate fluorapatite (CFA). The increase in authigenic P burial during climate warming is likely to partially counter the effects of increased water-column P regeneration rate during climate warming events, and thus influence the extent of oceanic anoxia and organic matter burial, a factor that should be considered when assessing the response of the P cycle in the face of warming.

Selecta Recreation Park is one of the tourist recreational parks located in Batu City and is one of the tourist attractions that is able implement health protocols to provide comfort and health for tourists who want to visit in the midst of the ongoing pandemic. One of the things that becomes an important point during a pandemic when tourists visit tourist attractions is how they perceive the risks they face will generate trust from tourists in the tourist attractions they visit. This study aims to determine the effect of implementing health protocols on tourist trust with perceived risk as an intermediate variable. The research sample used in this study was domestic tourists who visited the Selecta recreational park with a total of 100 respondents. The data analysis technique is quantitative descriptive analysis using partial least squares (PLS) analysis to determine the effect of the independent variables on the dependent variable and the intermediate variables in it. The results obtained in this study show that the application of the CHSE health protocol has an effect the confidence of domestic tourists with a t-statistic value of 4.960 which is greater than the t-table (1.96) with a p-value of 0.000. Furthermore, the risk perception variable has an influence on trust with a t-statistic value of 2.057 which is greater than t-table (1.96) and a P-value of 0.003. on the effect of the risk perception variable on trust, the t-statistic value of 2.507 is greater than the t-table of 1.96 with a p-value of 0.013 which indicates that risk perception affects the confidence of domestic tourists who visit the Selecta recreation park. Furthermore, on the indirect effect between the CHSE health protocol on tourist trust, where the perception of risk as an intervening variable gets a t-statistic value of 1.985 which is greater than the t-table of 1.96 with a p-value of 0.048. These results indicate that the application of health protocols indirectly affects the confidence of domestic tourists with the perception of risk as an intervening variable.
