Summary
A new chatbot, ChatLinoHans, was developed to aid healthcare professionals in managing leprosy. It demonstrated high validity and usability in expert and technical assessments, showing promise as a valuable support tool.
Area of Science:
- Medical Informatics
- Dermatology
- Human-Computer Interaction
Background:
- Leprosy management requires specialized knowledge and support for healthcare professionals.
- Existing tools may not adequately address the specific needs of leprosy care.
- A digital support tool could enhance the efficiency and effectiveness of leprosy management.
Purpose of the Study:
- To develop, validate, and test the usability of a chatbot named ChatLinoHans.
- To assess the chatbot's potential as a support tool for healthcare professionals managing leprosy lesions.
- To ensure the chatbot meets content and appearance standards for clinical use.
Main Methods:
- Methodological study adhering to SQUIRE 2.0 and OHDM principles.
- Content validation by ten healthcare professionals (Content Validity Index [CVI] = 0.98).
- Appearance validation by seven ICT specialists (agreement rates 85.7%-100%) and usability testing (scores 77.5-100).
Main Results:
- ChatLinoHans achieved a high CVI of 0.98, indicating strong content validity.
- Appearance validation showed high agreement among technical judges, confirming aesthetic and functional adequacy.
- Usability testing yielded scores indicating above-average performance, suggesting user-friendliness and effectiveness.
Conclusions:
- The ChatLinoHans chatbot is a credible and legitimate tool for supporting healthcare professionals in leprosy management.
- The chatbot's appearance and usability were validated, confirming its suitability for intended users.
- ChatLinoHans shows significant potential as an effective digital support system in clinical dermatology for leprosy care.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
