Skin Cancer

5.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Skin Diseases and Disorders

4.5K
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...

Clinical Applications of Epidermal Stem Cells

3.0K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Area of Science:

  • Dermatology
  • Medical Informatics
  • Computer Science

Background:

  • Skin cancer is the most common cancer type, necessitating improved diagnostic tools.
  • Current medical data analysis often centralizes sensitive data, posing privacy and regulatory challenges.
  • The Personal Health Train (PHT) offers a decentralized approach, moving algorithms to data.

Purpose of the Study:

  • To assess the feasibility of the PHT infrastructure for analyzing distributed skin lesion data.
  • To demonstrate a privacy-preserving method for machine learning in dermatology research.

Main Methods:

  • A feasibility study was conducted using the Personal Health Train (PHT) infrastructure.
  • Distributed Analytics (DA) was employed, bringing algorithms to data sources instead of centralizing data.
  • Statistical analyses and Machine Learning models were applied to skin lesion datasets from three German data providers.

Main Results:

  • The PHT successfully performed statistical analyses on distributed skin lesion data.
  • Machine learning tasks were effectively executed across decentralized datasets.
  • The study demonstrated the PHT's capability to handle sensitive medical data while respecting privacy.

Conclusions:

  • The Personal Health Train (PHT) is a viable solution for privacy-preserving distributed analytics in medical research.
  • This approach overcomes data centralization limitations and enhances data sovereignty for medical data providers.
  • The PHT facilitates advanced analysis, including machine learning, on sensitive skin lesion data.
