The microbiome is mainly composed of lactic acid rods – <italic>Lactobacillus</italic>, the metabolism of which ensures an acidic pH, playing a protective role for vaginal homeostasis. One of the typical disorders of homeostasis is bacterial vaginosis, defined as predominance of group IV CST system bacteria (comprising different genera characterized by anaerobic metabolism), which is an essential problem of the female population all over the world. The maintenance of this homeostasis can be restored by medicinal preparations. In addition to well-known antibiotics aimed at inhibiting the development of bacterial pathogens, probiotics and products that promote the development of beneficial microbiota are increasingly used. It seems more relevant not to cure, but to prevent imbalance of homeostasis. For this purpose, women use different washing and care techniques of external genitalia. Women’s everyday practices also include the use of washing preparations from the group of cosmetics; however, little is known about their impact on the microbiota. These products potentially constitute an element of early prevention, which is highly beneficial for female health. The main controversial type of ingredients are cleaning surfactants, which can lead to disruption of the epidermal barrier and to breakthrough of pathogens.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2024-00032024-04-09T00:00:00.000+00:00Investigation of antimicrobial susceptibility, class I, II, and III integrons among clinical isolates of from hospitalized burn patients in Southern Iranhttps://sciendo.com/article/10.2478/ahem-2023-0011<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>Burn infection due to <italic>Pseudomonas aeruginosa</italic> poses a considerable challenge in terms of graft loss, systemic sepsis, prolonged hospital stays, and even enhanced mortality.

According to the latest WHO data 80,491 leukemias were diagnosed in 2020 alone. In the coming years the incidence worldwide will continue at a similar level. The morbidity correlates with biological determinants such age, gender and race. The etiology of leukemia formation is complex and depends on genetic, physiological, environmental and even prior treatment-related factors. Both the incidence and curability are also influenced by age, gender, and race. The peak of incidence of leukemia occurs between the ages of 1–4 years and 9–19. The etiology of leukemia formation is complex and depends on genetic, physiological, environmental and even prior treatment-related factors. Boys suffer from leukemia more often than girls. In 2020 58.2% of diagnoses were for boys. Numerous factors contribute to the development of acute leukemia. In the case of young children, a notable association exists between acute leukemia and infections caused by viruses such as EBV or HHV-6. Furthermore, the risk of leukemia can be elevated by allergies, which involve Th1/Th2 lymphocyte-dependent mechanisms. A familial predisposition to tumorigenesis in children is observed in Li-Fraumeni Syndrome. Also, genetic diseases such as Down syndrome and Fanconi anemia are associated with an increased risk of acute leukemia. Previous exposure to radiation therapy or the use of anti-cancer drugs can also lead to the development of secondary cancers, including leukemia. The analysis of risk factors can be used to support efforts aimed to reduce potentially harmful exposure and to decrease the risk of disease.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2023-00232024-03-14T00:00:00.000+00:00A debate on elimination of dog-mediated human rabies in developing countries by 2030https://sciendo.com/article/10.2478/ahem-2023-0026<abstract> <title style='display:none'>Abstract</title> <p>Rabies is a vaccine-preventable viral disease that affects over 150 countries and territories worldwide. This neglected disease is almost always fatal once clinical signs manifest and is thus responsible for approximately 59,000 annual deaths. Due to globalization, rabies continues to be seen as a disease of developing countries and more emphasis, both nationally and internationally, is put on fighting infectious diseases that also affect economically developed countries. Even though the elimination of dog-mediated rabies in Europe and North America has proved the possibility of its eradication, rabies is still a persistent public health concern in low- and middle-income countries. It is believed that the interplay of sustainable investment strategies and rabies education, through developed countries, could positively affect the cooperation of culturally diverse regions and could help garner coordinated action from different areas affected by dog-mediated rabies. Breaking the rabies transmission cycle requires a comprehensive approach that includes increased vaccination efforts, improved surveillance and control of wildlife populations, and public education and awareness. More global effort must be put into these efforts to effectively combat the spread of rabies and protect public health. We herein examine various strategies and innovative financing methods for eliminating dog-mediated human rabies from the developing world to achieve the World Health Organization’s (WHO) goal of zero rabies deaths by 2030.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2023-00262024-03-07T00:00:00.000+00:00Ocular ischemic syndrome – case report and literature analysishttps://sciendo.com/article/10.2478/ahem-2024-0001<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>Ocular ischemic syndrome (OIS) is a rare condition associated with ocular hypoperfusion caused by carotid artery occlusive disease.

There are many mechanisms that determine the development of taste disorders. One of them is believed to be zinc deficiency. Zinc is responsible for the processes of regeneration of taste and smell centres. It plays a significant role in the cells of the taste bud. Our study aims to present the role of zinc deficiency on the occurrence of taste disorders in selected medical aspects, such as in the course of diabetes, as a result of radiotherapy and chemotherapy of head and neck cancers, resulting from old age, and in the course of oral cavity halitosis. The study analyzed articles available in the PubMed database. The consequence of the reduced zinc content is its incorrect amount in the epithelium of the tongue, which may be the result of a reduced ability of cells to regenerate after the destructive effects of pathological factors. The result of zinc deficiency is its reduced amount in the salivary glands, which results in reduced activity of carbonic anhydrase 6 (gustin), which is a component of saliva. Zinc is also involved in the process of experiencing taste by affecting neuronal processes. Zinc ions inhibit oral malodor by binding directly to hydrogen sulfide gas and by inhibiting the growth of oral bacteria that produce volatile sulfur compounds. In the study, we focus on the mechanisms that determine the abnormal perception of taste and potential therapeutic possibilities based on current scientific reports.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2023-00252023-12-31T00:00:00.000+00:00Comparison of the effects of orbital decompression in Graves' ophthalmopathyhttps://sciendo.com/article/10.2478/ahem-2023-0021<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title><p>Graves' disease is an autoimmune disorder.

A mini-review of current conceptshttps://sciendo.com/article/10.2478/ahem-2023-0015<abstract> <title style='display:none'>Abstract</title> <p>Obesity is a chronic, relapsing, and progressive disease that leads to negative health consequences. Excessive adiposity frequently coexists with metabolic and nonmetabolic complications, deteriorating health and reducing quality of life and life span. Individuals with obesity are not a homogenous group and can present different obesity phenotypes. The most common obesity phenotypes include: metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO). The latter category involves those with developed metabolic syndrome (MetS) and non-fully-developed metabolic syndrome (pre-MetS). The fundamental factor leading to obesity is imbalance between energy uptake and expenditure. From this perspective the thyroid gland plays the pivotal role in metabolism regulation and obesity development. The thyroid regulates thermogenesis, appetite, and lipids turnover. Clinically, hypothyroid patients have decreased metabolic rate and subsequently experience increase of BMI and excess adiposity. The interaction between the thyroid gland and obesity is bidirectional. Several mechanisms of alteration of the hypothalamus-pituitary-thyroid axis in obesity are proposed. Excessive adiposity and dysfunction of adipose tissue may contribute to the development of thyroid functional and structural impairment, such as autoimmunity, thyroid nodules, and thyroid cancer. The prevalence of certain thyroid disorders in obese individuals is higher than in nonobese subjects and this trend is more pronounced in unhealthy obesity phenotypes. The aim of this mini-review is to present the current knowledge on the interaction between thyroid gland disorders and obesity, with special focus on obesity phenotypes.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2023-00152023-10-31T00:00:00.000+00:00The influence of reinnervation on the results of peripheral nerve repair after injurieshttps://sciendo.com/article/10.2478/ahem-2023-0012<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>Research on the possibility of increasing the effects of after-injury reconstruction of peripheral nerves conducted in the Department of Physiology at ŚUM resulted in the development of a new method of reconstruction after peripheral nerve injuries.

In clinical assessment, we concluded that recovery in motor, sensory and vegetative function after peripheral nerve injury treatment is better with the use of predegenerated grafts. The latent efficacy of reconstruction was measured months or years after reconstruction. In that amount of time, denervated synaptic sites in muscles can be reinnervated by nearby healthy non-injured nerves.

The pathology of DIHS has been connected with adverse reactions to drugs; however, it has been observed that viruses and other infectious factors may induce similar responses in the body. COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has recently become a major challenge for worldwide healthcare. The dermatological symptoms occur in approximately 5.95% of COVID-19 patients, however, they are not exclusively a manifestation of SARS-CoV-2 infection.</p> <p>Certain skin-related symptoms might result from therapeutic drug administration, personal protective equipment, or sanitizers used by medical personnel. The complex pathomechanism of those symptoms leads to multiple diagnostic difficulties. This article describes a case of a 40-year-old man who was admitted to the intensive care unit (ICU) due to heavy respiratory failure in the course of SARS-CoV-2 infection. The patient has been treated with olanzapine for anxiety disorder for approximately 4 years. On the seventh day of treatment, the patient presented with a maculopapular rash, fever, and swollen upper lip. Because of these presented symptoms, the patient has been diagnosed with drug-induced hypersensitivity syndrome (DIHS). The results of blood analysis showed elevated levels of acute phase markers, liver and kidney damage markers, which are present both during COVID-19 and DIHS. Furthermore, the patient presented with peripheral eosinophilia, which is a distinctive feature of DIHS. In the course of COVID-19, the laboratory-measured levels of eosinophilic granulocytes declined to 0. Therefore, in the active phase of SARS-CoV-2 infection, the eosinophilia connected with DIHS was difficult to assess. In this paper, we compare and contrast the clinical and laboratory symptoms of COVID-19 and DIHS syndrome, describe patient's case and explain the diagnostics difficulties resulting from the concomitance of those disease entities.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ahem-2023-00162023-10-08T00:00:00.000+00:00The carbohydrate-deficient transferrin as a marker of chronic alcohol consumption and assessment of its usefulness in patients with cardiovascular diseases – a pilot studyhttps://sciendo.com/article/10.2478/ahem-2023-0010<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>Cardiovascular diseases (CVDs) are the leading cause of death in the world.
