Endophthalmitis after intravitreal injection with or without triamcinolone – A 10-year investigation in a tertiary hospital
Authors: Chen Yen-Ju , Yeh Cyuan-Yi , Cheng Cheng-Kuo
Published: February 2025

PURPOSE:

Intravitreal injections (IVIs) have been the most important treatment strategies in retinal diseases. With the increasing use of IVIs, the incidence of endophthalmitis has inevitably risen. Triamcinolone acetonide (TA) used in IVIs has been suspected as a risk factor for post-IVI endophthalmitis. This study investigates the incidence, clinical presentations, and microscopic findings of post-IVI endophthalmitis with or without TA, aiming to provide a better understanding of this issue.

MATERIALS AND METHODS:

This retrospective study included patients receiving IVIs at a tertiary referral center from September 2010 to August 2020. Injections were performed under sterile conditions, and endophthalmitis was diagnosed based on acute ocular symptoms within 6 weeks postinjection. Statistical analysis was preformed between endophthalmitis with or without TA.

RESULTS:

Out of 18,365 IVIs, the incidence of endophthalmitis was 0.038%. The incidence of TA-associated endophthalmitis (TAAE) (5 in 939 IVIs, 0.532%) was significantly higher (P < 0.0001) than that of non-TAAE (2 in 17,426 IVIs, 0.011%). All five TAAE cases were culture negative, while the two non-TAAE cases were culture positive with Staphylococcus epidermidis (P < 0.0001). The outcomes for TAAE were generally good, with patients returning to their preendophthalmitis vision levels. Risk factors for TAAE included prior IVIs and prior TA injections. Microscopy revealed fern-like crystalline materials in the anterior chamber of one TAAE case.

CONCLUSION:

This study highlights that TA is significantly associated with a higher incidence of post-IVI endophthalmitis, which is also significantly associated with culture-negative results. This implies the possibility of a noninfectious cause in TAAE.

Introduction. In 2025, we will commemorate the 100th anniversary of the first pediatric case of Guillain–Barré Syndrome (GBS), initially documented by M. Monnier-Vinard. This significant milestone invites a reevaluation of our contemporary understanding of GBS in children. While the original description of GBS was thorough, the categorization has expanded over time to include a wider array of conditions, resulting in the term applied to various acute demyelinating polyneuropathies. The atypical forms of GBS present notable diagnostic challenges for healthcare providers.
Objective. To analyze the demographic and clinical characteristics, treatment methods, and prognosis of GBS in children in Russia.
Materials and methods. The study included fifty 6 months – 15 years patients with typical and atypical forms of Guillain-Barré syndrome (GBS). Neurological status was assessed using the Medical Research Council sum score and the Hughes disability scale. Additionally, data from cerebrospinal fluid analysis, nerve conduction study, magnetic resonance imaging of the spine, and peripheral nerves ultrasound was evaluated.
Results. The classic ascending subtype of GBS was diagnosed in 30 (60%) patients, while atypical manifestations were observed in 17 (34%). Three (6%) patients had an overlap syndrome: GBS with acute myelitis. The median age of the patients was 7 [5.0; 11.0] years. Two peaks of GBS incidence associated with respiratory and gastrointestinal infections were identified. The most common initial symptoms were pain (80%), weakness in the legs (64%), and difficulty walking (54%). All 26 (100%) GBS patients were followed for 12 months from the onset of the disease regained the ability to walk.
Conclusion. Both typical and atypical forms of GBS can occur in children. Overlap syndrome (GBS with acute myelitis) is a rare complication following COVID-19 and may go undiagnosed. With appropriate therapy the prognosis for both typical and atypical forms of GBS is generally favourable.
Features of the genetic diagnosis of merosin-deficient muscular dystrophy (a clinical case)
Authors: Monakhova Anastasia V. , Vlodavets Dmitry V. , Kanivets Dmitry V.
Published: February 2025

Merosin-deficient muscular dystrophy is a rare neuromuscular disease characterized by diffuse muscular and epileptic seizures. The disease is inherited in an autosomal recessive type and occurs as a result of biallelic variants in the LAMA2 gene. In this gene there are described all types of violations of the normal nucleotide sequence (single nucleotide variants, variations in the number of DNA copies) which can lead to difficulties in genetic search. The combination of phenotype features (hypomimia, elongated face, ophthalmoparesis, muscle hypotonia, and weakness, spinal rigidity, contractures of large joints), laboratory and instrumental research results (increased activity of creatinephosphokinase in the blood, leukopathy on brain MRI) will help you choose the right diagnostic search tactics. In this article, we present a clinical case of a patient with three identified variants in the LAMA2 gene: two point substitutions (c.4048C>T and c.4860+75G>C) and deletion of exons 2 and 3. The use of several methods of genetic testing (high-throughput sequencing, chromosomal microarray analysis, Sanger sequencing) allowed the establishing of the diagnosis, which subsequently led to successful prenatal diagnosis and the birth of healthy siblings.

Published: February 2025

L-aromatic amino acid decarboxylase deficiency (AADC) is a rare autosomal recessive neurometabolic disease characterized by impaired biosynthesis of neurotransmitters and manifested by disorders of movement and autonomic regulation. In the article there is discussed the diagnostic path and treatment options for a 7-year patient with severe AADC deficiency. Combination of severe neurological disorders (muscular hypotension, dystonia, hyperkinesis, oculogyric crises) and autonomic disorders (increased sweating, hypersalivation, thermoregulation disorders, nasal congestion, dyspepsia, etc.) is clearly demonstrated to require the detection of 3-O-methyldopa in dried blood spots to exclude AADC deficiency. Given the emergence of gene therapy, which is available to patients with a confirmed diagnosis of AADC deficiency in Russia within the criteria of the Circle of Kindness Foundation, it is necessary to popularize information about L-aromatic amino acid decarboxylase deficiency in the general medical community, to improve the prognosis and quality of life in AADC patients.

Published: February 2025

Poverty is one of the crucial social problems in rural areas. The problem of poverty in rural areas is increasingly in the spotlight because of its broad impact on the community's economic and social sustainability. The varying levels of poverty require an appropriate analytical approach to design effective intervention programs. In an effort to understand and address this problem, this study uses the K-Means Clustering method to group the poor population. We use K-Means clustering to identify and group hamlets based on their poverty levels. This study aims to categorize the hamlets in Bandar Kumbul Village into multiple clusters according to their poverty levels, thereby identifying which hamlets necessitate more focused attention. The research methods used include collecting data on the number of poor people from 2013 to 2022 in each hamlet, data preprocessing, applying the Elbow method to determine the optimal number of clusters, and applying the K-Means Clustering algorithm to group the hamlets. The results of the study show that there are three main clusters with different characteristics. Cluster 0 includes Hutaimbaru and Mailil Julu hamlets with high poverty levels. Cluster 1 only includes the Pasir Sidimpuan hamlet, which has medium poverty levels. Cluster 2 includes Aek Mardomu, Bandar Kumbul, Mailil Jae, Sidodadi, and Singga Mata hamlets with low poverty levels. Variations in distance from the cluster center indicate significant differences in the distribution of poverty in each hamlet. The K-Means Clustering method is effective in identifying and grouping hamlets based on poverty levels, providing useful insights for the government and stakeholders to design more targeted intervention programs. Clusters with high poverty levels require immediate intervention, while clusters with medium and low poverty levels require maintenance and support to prevent an increase in poverty. This study provides a strong foundation for decision-making and policies to reduce poverty levels in Bandar Kumbul Village more effectively and sustainably.

Authors: Xursanovna Umurzakova
Published: February 2025

This article explores the widespread use of slang and abbreviations among youth in social networks and their impact on language development and communication. While slang and abbreviations serve as tools for quick interaction among youth, they can negatively affect literary language and deepen generational linguistic gaps. The study provides solutions and recommendations based on the findings. This study examines the widespread use of slang and abbreviations among youth on social media, analyzing their linguistic, social, and cultural impacts. A mixed-methods approach was employed, including surveys (150 participants aged 18–25), interviews, qualitative and quantitative analysis, and document review. Results indicate that while slang enhances communication efficiency and social bonding, excessive usage degrades literary language standards and intergenerational communication. Although 62% of participants use slang in formal settings, 68% believe it contributes to language deterioration. The study concludes that balancing slang use with literary language preservation is crucial for maintaining linguistic and cultural integrity.

Published: February 2025

Introduction. Anthropogenic impact has affected the state of the lower reaches of the Don River, while reducing the natural reproduction of commercial fish species. Currently, for the conservation and reproduction of commercial fish species, passing and semi-passing fish species are released into the reservoir. Therefore, water quality control, including for the content of heavy metals, of the Lower reaches of the Don is especially important.
Materials and methods. The paper presents data from the analytical testing center of the Azov-Black Sea branch of the Russian Research Institute of Fisheries and Oceanography. Water samples were collected at eight monitoring stations in the lower reaches of the river. Dissolved forms of metals such as copper, lead, cadmium, and nickel were detected in the samples.
Results. In the course of research, in some samples the concentrations of copper were found to exceed MPC. Such metals as lead, cadmium, and nickel did not exceed MPC throughout the study. Annual and seasonal trend in metal concentrations in water were also established.
Limitations. The limitation of the research of this work lies in the fact that water samples were taken in the lower reaches of the Don River at only 8 monitoring stations, which does not provide complete information on the territory of the entire region.
Conclusion. The content of heavy metals such as lead, cadmium, and nickel in the water of the Lower Don is safe for the purposes of aquaculture and reproduction of commercial species, since no exceedances of MPC were detected. However, the copper content in some water samples exceeded the MPC, which indicates the contamination of the reservoir, as well as the need to carry out a set of measures to purify water in this facility.

Published: February 2025

Introduction. The paper presents the results of a study on the hygienic assessment of the cationic-anionic composition of drinking water of centralized water supply in the administrative centers of the Vladimir region.
Materials and methods. The object of the study was the water of the sources of the central water supply of the administrative centers of the Vladimir region. The content of water-soluble forms of anions and cations was determined by capillary electrophoresis. There were compared concentration values ​​with maximum permissible concentrations (MPC) and ranges of permissible hygienic standards (RHS).
Results. In some administrative centers, there has been established concentrations of nitrate ions, phosphate ions, magnesium ions, hardness exceeding the maximum permissible concentrations in drinking water of centralized water supply. Non‒compliance with permissible hygienic standards for chlorides in 16 localities was revealed as follows: for sulfates – in 11; for potassium ions – in 8; for sodium ions – in 9; for magnesium ions – in 3. Non-compliance with minimum RHS for calcium ions was found in the one city. The excess of RHS was noted in seven administrative centers for calcium ions. The drinking water of centralized sources in the city of Petushki is characterized by the highest compliance with hygienic standards (MPC and RHS) according to a set of indices; the smallest is the city of Murom.
Limitations are related to the one-time selection and small number of samples, which fails to allow for a broader interpreting of the obtained data.
Conclusion. The use of drinking water, the quality of which does not meet sanitary and hygienic requirements, may cause an increase in both the level of general morbidity of the population and in certain nosological forms. In order to reduce the potential adverse impact of drinking water with a high content of nitrate ions, phosphate ions, hardness salts on health, the population is recommended to use household water purification filters, the principle of operation of which is based on methods of adsorption and ion exchange, as well as to use household reverse osmosis systems with a mineralizer, allowing to purify drinking water by the membrane method get rid of excess anions and hardness salts and saturate it with trace elements necessary for the human body.

Authors: Syurin Sergei A.
Published: February 2025

Introduction. The high level of occupational morbidity in apatite miners emphasizes the unresolved problem of maintaining their health throughout the entire period of their working activity.
Aim. To study the characteristics of the occupational health in miners of various occupations engaged in open-pit and underground apatite ore mining.
Material and methods. The following databases were examined: 1) the results of medical examination of nine hundred twenty one open-pit and 2649 underground apatite miners; 2) the register of occupational diseases of the Murmansk Regional Center for Occupational Pathology; 3) the register of occupational disease records (Order of the Ministry of Health of Russia dated May 28, 2001 No. 176) in 2008–2021.
Results. In 2008–2021 occupational morbidity in underground and open-pit apatite ore miners at the Khibiny deposits reached 208.62 and 170.95 cases/10,000 workers. The increased labour severity (60.7%) and hand-arm vibration (10.1%) were of greater etiological importance in underground miners, while whole-body vibration played a more important role in open-pit miners (33.5%). In the structure of pathology, open-pit miners had a larger share of vibration disease (χ2=24.7; p<0.001), and in underground miners – scapulo humeralis periarthrosis (χ2=12.5; p<0.001), epicondylosis (χ2=7, 44; p=0.007), myofibrosis of the forearms (χ2=12.3; p<0.001), deforming osteoarthritis (χ2=7.58; p=0.006). Occupational diseases developed most often in drifters, underground mine drillers, and open-pit excavator operators: 40.8%, 39.1% and 35.1% of workers. The maximum incidence rate was found among drillers, while the minimum rate was in underground repairmen: 738.92 and 19.62 cases/10,000 workers.
Limitations. The number of observations in some groups of specialists is insufficient for statistical processing.
Conclusion. The new data obtained show that updated health-building measures should take into account the method of apatite ore mining and the specialty of the miners.
The effect of obstructive sleep Asghari on hearing impairment: A Cross-Sectional Study among Noise-Exposed Workers
Authors: Kabir-Mokamelkhah Elaheh , Aghilinejad Mashallah , Omid Asghari , Amini Marjan
Published: February 2025

Purpose. The principal goal of this investigation was to assess how obstructive sleep apnea affects hearing impairments in workers who are regularly exposed to occupational noise.
Materials and methods. In this investigation, we assessed 920 noise-exposure workers in one of the metal industries in Iran. Noise-induced, high-frequency, and low-frequency hearing loss were classified based on the mean hearing thresholds of more than 25 dB at 500–2000 Hz, 300–8000 Hz, and 4000 Hz, respectively. We used the STOP-Bang questionnaire for screening for sleep apnea, and a score of ≥3 indicated a high risk of obstructive sleep apnea.  Multivariable logistic regression analyses were used to evaluate the correlation between hearing impairment and obstructive sleep apnea risk.
Results. The mean hearing thresholds at 3000–8000 Hz and specifically at 4000 Hz were significantly higher among workers at high risk for obstructive sleep apnea compared to those at low risk (p-value <0.05). Following the multivariate logistic regression analysis and the confounding factor adjustment, individuals with high obstructive sleep apnea risk showed a higher incidence of noise-induced hearing loss (p = 0.002, OR = 1.85, 95% CI = 1.28–2.36) and high-frequency hearing loss (p = 0.02, OR = 2.05, 95% CI = 1.28–2.16) compared to those with low risk.
Limitations. The cross-sectional design and use of a subjective screening method instead of objective methods such as polysomnography for evaluating obstructive sleep apnea are weaknesses of this study.
Conclusion. The current study showed obstructive sleep apnea in noise-exposed workers increased the risk of developing high-frequency hearing loss and hearing impairment from noise. So, identifying and managing workers with obstructive sleep apnea risk, early hearing screening, and periodic audiometry can help to prevent hearing loss in the primary stage.

Zina merupakan hal yang rumit di dalam prakteknya, sebab  untuk mengetahui adanya  perzinahan   tersebut bukanlah  hal  yang mudah dan  umumnya hanya dapat dilakukan dengan persangkaan saja. Penelitian yang dilakukan adalah penelitian normatif dan didukung dengan data empiris. Data yang dipergunakan adalah data primer dan sekunder dan metode pengumpulan data yang digunakan dalam penelitian ini adalah penelitian kepustakaan Analisis data yang digunakan adalah data kualitatif. Upaya yang dilakukan penyidik Kepolisian Resort Kota Medan dalam mengurangi tindak pidana perzinahan adalah dengan melakukan upaya preventif yaitu melakukan pencegahan dan represif yaitu menjerat pelaku tindak pidana perzinahan dengan ancaman hukuman yang berat. Disarankan agar tindak pidana perzinahan (Pasal 284 KUHP) yang berlaku saat ini harus segera diganti karena telah gagal menjalankan fungsi pencegahannya dari berbagai dampak buruk yang mengancam masyarakat di Indonesia.

El artículo analiza las tasas mensualizadas de los delitos de alto impacto por cada cien mil habitantes en las localidades donde estarán ubicadas las dieciséis estaciones de la Primera Línea del Metro de Bogotá, abarcando el periodo entre el 2018 y el 2023. Para esto se aplicó una metodología cuantitativa descriptiva a través de un análisis exploratorio de series de tiempo, examinando los comportamientos promedio de los delitos antes, durante y después de las medidas que se tomaron contra el Covid-19. Se aplicaron la prueba de Dickey-Fuller aumentada, el índice de estacionalidad y pruebas de correlación de Spearman para identificar patrones de estacionalidad y correlación entre los datos recolectados. Este enfoque proporciona una comprensión de la evolución de las tasas de estos delitos. Como resultado se observa que el comportamiento promedio de las tasas de delitos de alto impacto en cada momento analizado no fue similar para todos. En particular, se identificó el mínimo para el mes de abril de 2020 en varios delitos de alto impacto en las distintas localidades. Por otra parte, se resalta que desde el segundo semestre del 2022 se registran los mayores picos de hurtos a personas en los espacios revisados.
