Estudio de la etiología, patogenia y diagnóstico de las dermatomicosis del cuero cabelludo, uñas, pies, manos, piel lisa y dermatofitosis inguinal

Introduction: The increased incidence and preponderance of dermatomycosis cause the issue of determining antimycotic agents of systemic and external action to be particularly pertinent, considering the etiology, clinical form, and majority of mycoses, the sensitivity of pathogens to them, and the existence of concurrent conditions. The study aims to analyze the etiology, pathogenesis, and diagnosis of dermatomycosis of the scalp, nails, feet, hands, smooth skin, and inguinal dermatophytosis. Patients and methods: To meet the aim of the study, it is attempted to generate an algorithm for pharmaceutical counseling of patients suffering from various types of dermatomycosis. Over the span of five months, a survey was carried out of 25 visitors to the pharmacy with a diagnosis of dermatomycosis. Results: Based on the results, it was revealed that most of the visitors suffer from dermatomycosis of the feet - 10 people (40%), the second in terms of incidence is onychomycosis - 5 people (19%), the third in terms of incidence is dermatomycosis of the groin area - 4 people (15%), the fourth in the incidence is dermatomycosis of the scalp - 4 people (14%). Conclusion: To treat different types of dermatomycosis, various antifungal drugs in different dosage forms can be used. For each type of disease, a specific course of treatment is selected. The duration of the course of treatment depends on the skin lesion area, the duration of the disease, and the presence of complications.Introducción: El aumento de la incidencia y preponderancia de las dermatomicosis hace que el tema de la determinación de agentes antimicóticos de acción sistémica y externa sea particularmente pertinente, considerando la etiología, forma clínica y mayoría de las micosis, la sensibilidad de los patógenos a las mismas y la existencia de condiciones.

Pacientes y métodos: Para cumplir con el objetivo del estudio, se intenta generar un algoritmo para el asesoramiento farmacéutico de pacientes que padecen diversos tipos de dermatomicosis. Durante cinco meses se realizó una encuesta a 25 visitantes de la farmacia con diagnóstico de dermatomicosis. Resultados: Con base en los resultados, se reveló que la mayoría de los visitantes padecen dermatomicosis de los pies - 10 personas (40%), el segundo en cuanto a incidencia es la onicomicosis - 5 personas (19%), el tercero en cuanto a la incidencia es dermatomicosis del área de la ingle - 4 personas (15%), el cuarto en la incidencia es dermatomicosis del cuero cabelludo - 4 personas (14%). Conclusión: Para tratar diferentes tipos de dermatomicosis, se pueden utilizar diversos fármacos antifúngicos en diferentes formas de dosificación. Para cada tipo de enfermedad, se selecciona un curso de tratamiento específico. La duración del curso del tratamiento depende del área de la lesión cutánea, la duración de la enfermedad y la presencia de complicaciones

Turbulent Transport in a Stratified Shear Flow

Within the framework of the theory of unsteady turbulent flows in a stratified fluid, a new parameterization of the turbulent Prandtl number is proposed. The parameterization is included in the k-ε-closure and used within the three-dimensional model of thermohydrodynamics of an enclosed water body where density distribution includes pycnocline. This allows us to describe turbulence in a stratified shear flow without the restrictions associated with the gradient Richardson number and justify the choice of closure constants. Numerical experiments, where the downward penetration of turbulence was considered, confirm the advantage of the developed approach in describing the effects neglected in the classical closures

A new setup for the study of adsorption/desorption processes and nanoparticles formation in porous alumina

We present a setup devoted to the study of adsorption and desorption processes of alkali atoms after deposition on a 300 nm thick porous alumina substrate in an Ultra High Vacuum chamber. Rubidium atoms, delivered by a dispenser source, enter the 20-30 nm diameter pores, diffuse in and stick to their walls. A 1 W power laser is used in order to induce detachment and take the atoms back in the vapor phase in a very tight confinement region. The desorbed atoms coming out the sample can be monitored via both a resonant optical detection and an electronic amplifier after ionization. The desorbing laser is also able to promote the formation of Rubidium nanoparticles, as the high Rb vapor density in the pores favors aggregation around nucleation point defects. In this way, the apparatus allows for the study of the fundamental processes related to atom – surface interactions in presence of light as well as of several promising application to nanomaterials
