Global Healthcare Issues in Dermatology

Evelyn Chow 


With global atmospheric temperatures rising, skin health is becoming more vulnerable, especially in parts of the world with limited access to medical care. In hotter regions like Africa, South America, and South Asia, people are exposed to intense sun rays and excessive heat. Climate change brings high humidity, which can weaken the skin barrier, allowing bacteria to penetrate more easily and cause infections such as fungal rashes and sores.

The increased heat also causes more sweating, trapping moisture on the skin. This creates an environment where skin conditions like heat rash, fungal infections, and acne thrive, especially in low-resource communities where clean water and hygiene products are scarce. Additionally, sun exposure is a major concern. Over time, exposure to ultraviolet radiation can result in sunburn, premature aging, and skin cancer. While people with darker skin have some natural protection due to melanin, it is still possible to get skin cancer. Unfortunately, in many of these regions, sunscreen is usually too expensive or not widely available. When skin cancer does occur, it is not easy to treat, especially given the shortage of dermatologists. According to Oxford Academic, many African countries have fewer than one dermatologist for every one million people. This lack of specialists means that many skin conditions go untreated or that people are not taught how to prevent them.

As climate change persists, increasing the number of trained dermatologists in underserved communities and teaching the importance of treating skin conditions would greatly improve early diagnosis. Improving skin health is crucial to lessen suffering and support fair access to healthcare worldwide.

  Understanding Neurological Disorders: The Brain, Nervous System, and Common Disorders Andreah Falame Neurology is the branch of study in the medical field that focuses primarily on the brain, spinal cord, and the nervous system. The nervous system is a significant system that controls everything we do. From thinking and feeling to moving and sensing the world around us. The study of neurology is an emerging field that continues to advance in more personalized treatments for patients that are battling neurological disorders.   The field of neurology circles on 3 main parts of the nervous system. Starting off with the brain, the brain is known to be a complex organ that serves to process various information. With its ability to send signals throughout different areas of the body, it leads to the works of the spinal cord. The spinal cord carries messages between the brain and the rest of the body. With the help of the nerves, the nerves transmit signals to and from the bra...

  Highlighting the Global Healthcare Issues In Neurology. Neurology is the branch of medicine associated with the diagnosis and treatment of the nervous system, encompassing the brain and spinal cord. Furthermore, neurology is a paramount medical concern as it integrates physical and mental health, grasping how we behave, theorize, and recognize neurological health disorders that control our daily lives. Most importantly, everything starts with the brain — it makes us capable of functioning, executing daily habits and conversing with the people we love. Our brain should be calm, safe, and healthy. However, due to circumstances in the healthcare system, this is a privilege, rather than a basic need. In fact, this shapes the reality of many deployed soldiers, and Palestinian citizens suffering from chronic Multiple Sclerosis (MS) disease. MS occurs in the central nervous system, where the body accidentally attacks itself.  Moreover, due to the low-income healthcare system lackin...

Neurosurgery Iasmina Ciocan  Neurosurgery is, as we all know, one of the most demanding medical fields, due to needing utmost precision. Here, even the tiniest mistakes bring horrible consequences. Therefore, neurosurgery requires cutting-edge technology, dedicated professionals, and tremendous financial resources. Sadly, in low- and middle-income areas, the proficiency of neurosurgical care is being brought down by numerous challenges. People could always be affected by neurosurgical conditions, no matter which country they live in, hence it is essential to address the obstacles faced in this medical field, on a global level. One of these crucial problems is the absence of trained personnel and adequate surgical equipment. Specialized neurosurgical care is mandatory for conditions like hydrocephalus, brain tumors, congenital anomalies, and spinal cord injuries. However, the growing scarcity of skilled neurosurgeons and neurosurgical facilities in some countries, means that a notab...
