PORPHYRIA AND THE VAMPIRE DISEASE
By Benjamin Levinson, MD INTRODUCTION The term “Vampire” immediately conjures up an image of a person who fears the sun, sleeps in a coffin during the day, and hunts for victims at night to drink their blood. It is quite a story that many have believed over the centuries. It has been recognized that a possible origin for this legend is a disease called porphyria (1). The term ‘porphyria’ comes from the Greek work ‘purple’ as most people who have this d

Activation of the Mesolimbic Pathway: What Happens When We Eat Sugar?
Introduction Why does a slice of cake feel so satisfying even when we are hungry? Beyond taste, beyond calories, beyond sweetness, sugar activates a network in the brain structure known as the mesolimbic pathway. When we eat sugar, this system releases dopamine, reinforcing behaviours the brain interprets as rewarding. While this response is a part of normal human physiology, the frequency and intensity with which it is stimulated in modern dietary environments is historicall

Is Too Much Potassium Bad for You? Understanding Hyperkalemia
If you've ever gotten muscle cramps before, one piece of advice you may have heard is "Make sure you eat some bananas!" Why? Because bananas have a lot of potassium. Potassium is an essential electrolyte that helps muscles and nerves function. What is hyperkalemia? While potassium is important, too much potassium can cause problems in your body. The most serious problems it can cause include paralysis and cardiac arrest (stopping your heart). "Hyperkalemia" the medical term f

Eat for Your Genes: The Emerging Science of Nutrigenomics
Introduction Nutrigenomics is the scientific study of how an individual’s genes influence their response to nutrients, and how nutrients in turn can affect gene expression (2). This emerging field explores the biological relationship between diet and the genome, aiming to explain why people may respond differently to the same foods (2). Traditional dietary guidelines are often designed as universal recommendations (5). However, genetic variation means that individuals metabol

What If Precision Medicine Became Preventive, Not Reactive?
The Reactive Nature of Modern Healthcare Modern healthcare largely intervenes after disease appears. Diagnosis triggers treatment, and medical innovation often focuses on improving therapeutic precision rather than preventing illness altogether. Even within precision medicine, genomic sequencing and biomarker analysis are typically applied once pathology has already emerged. Yet disease rarely begins suddenly. Many chronic conditions develop through gradual molecular and phys

Rotational (Twisting) Deformities in Deformities in Children
Figure 1. Clinical assessment of tibial torsion in a child: (A) prone examination with the knees flexed to 90°; (B) measurement of the thigh–foot angle (TFA); (C) assessment of the external transmalleolar (tibial) torsion angle (ETT). Rotational deformities are common childhood differences in the way the legs and feet point while standing, walking, or running. Parents often notice intoeing (“pigeon toes”) or out-toeing (feet pointing outward). In most children these patter

Post-operative delirium (POD) is a common but serious complication following surgery, particularly in older adults, characterized by sudden confusion, disorientation, and fluctuating consciousness. Raising awareness among healthcare providers and families is crucial, not only for early detection and prevention but also for responding with patience and compassion, recognizing that behind the confusion is a person deserving of dignity and understanding.

Pulmonary Function Tests: Understanding How Well Your Lungs Work
Image Credit: Drugs.com What Are Pulmonary Function Tests? Pulmonary Function Tests (PFTs) are a set of breathing tests used to evaluate how well your lungs take in air, move it out, and diffuse oxygen throughout the body. They help healthcare providers understand lung performance and identify conditions that may affect breathing. These tests are often used in both routine checkups and specialty clinics. What PFTs Measure Rather than focusing on one single number, PFTs provid

Sighing: An Overlooked Respiratory Reflex in Pulmonary Physiology and Emotional Regulation
By: Nesredin Hassen Yesuf LinkedIn | Email Introduction Sighing is something we all do. Often, we do not think about it. It is a deep breath in and a long breath out. We usually sigh when we feel relieved, frustrated, or tired. Sighing also helps keep our lungs working properly. Even though we sigh all the time, scientists are still learning exactly how important it is. Sighing connects how our lungs work to how we feel. Understanding sighing helps us see how the body keeps t

What is Ortho-K? (A "Retainer" for Your Eyes)
Orthokeratology, usually called Ortho-K, is a non-surgical vision correction treatment. You can think of it like orthodontics, but instead of wearing a retainer to straighten your teeth, you wear a special rigid gas-permeable contact lens to correct your eyesight. According to the American Academy of Ophthalmology, Ortho-K is mostly used for people who are nearsighted (meaning they have trouble seeing things far away). It is a great option for people who want to see clearly w

Digital Eye Strain: A Growing Problem in the Smartphone Era
Causes of Digital Eye Strain Digital eye strain, also called computer vision syndrome, happens when we spend too much time using devices such as computers, smartphones, and tablets. Looking at small text and images for long periods makes our eyes focus continuously, which tires them out faster than normal. Reading on a screen for several hours without breaks can make it hard to focus and cause headaches or blurred vision. Another factor is blinking less while using screens. N

The one–Jab revolution: how a Kenyan Trial rewrote the future of cervical cancer prevention
Author Micah Sagini * For a long time, cervical cancer has been a global health concern for women globally. Cervical cancer ranks fourth among cancer-related causes of death in women worldwide, with more than 500,000 new cases and around 300,000 deaths each year. Unlike most cancers, cervical cancer is caused by a virus known as human papillomavirus (HPV), which infects the human reproductive system. This virus is responsible for over 95% of cervical cancer cases [1]. The d
