Inexplicable irrationality
For mysterious reasons, there have been anti-vaccination movements since vaccination was invented.* The eradication of smallpox from the earth; the near eradication of polio (which terrified the population in the 1950s); and the near elimination of measles, mumps, rubella, diphtheria, typhus and other diseases which formerly maimed and killed many children; and many other triumphs ought to have convinced people that vaccination was an unalloyed benefit to humanity. But somehow it ' s profitable to deny this obvious reality.The near miraculous success of the Covid 19 vaccines turns out to be one more opportunity for charlat...

Clinical Examination of Cardiovascular System For Medical Students
Discussion on blood pressure is not included here as a separate topic is dedicated to it. Though the most commonly examined pulse is the radial, to check some of the characteristics, a more proximal pulse like the brachial or carotid needs to be examined. Following parameters of the pulse are routinely documented: 1. The rate: Normal rate in adult is 60-100 per minute. It is higher in children. Younger the child, higher the pulse rate. Rhythm: Regular and irregular rhythms are possible. Mild variation with respiration is called respiratory sinus arrhythmia, with higher rate in inspiration. Respiratory sinus arrhythmia may...

The (sort of, partial) Father mRNA Vaccines Who Now Spreads Vaccine Misinformation (Part 2)
By DAVID WARMFLASH, MD This is part 2 of David Warmlash’s takedown of Robert W. Malone’s appearance (transcript) on the Rogan podcast. Part 1 is here Menstruation and Fertility Much more than the line about reproductive damage in the Wisconsin News clip that we used to open the story, Malone used the Rogan interview to dive more deeply into the topic, starting with:  …there’s a huge number of dysmenorrhea and menometrorrhagia… By that, he meant excessive menstrual cramping and very heavy, often irregular, bleeding, which he followed up with: …they DENY it… Judging by other parts ...

The Death Cult
While there has always been an anti-vaccination fringe, ever since there was such a thing as vaccination (and no, I ' m not sure why) the Republican party and conservatives have never as a class been hostile to the vaccine mandates that have been in place in every state for decades.Until now.  The ginned up hysteria about Covid-19 vaccine, based on batshit insane conspiracy theories about microchips and alterations to DNA and lizard people, was just one more manufactured outrage to stir up the MAGAts, like Critical Race Theory, the castration of Mr. Potatohead, and of course the Big Steal, better known as the Big...

Your New Life In 2021 (Mid-Post COVID)
At the beginning of the pandemic, we wrote a lot about how the pandemic should and could be handled. In addition to providing real-world advice on what technology can do to support us (like Digital Health Apps To Use During Quarantine or The State of A.I. in the Fight Against COVID-19), we often provided forecasts (When And How Will COVID End?) and predictions about the management and the potential outcome of the epidemic (Will There Be A Second Wave). We even created an entire handbook to give away for free! After drawing attention to the privacy and data protection issues raised by the pandemic (we issued a guide for ...

The Miracle of Modern Medical Research
Marian L. TupyHumanity has suffered from deadly diseases for millennia without fully knowing what they were, how they were transmitted, or how they could be cured. Smallpox, which killed between 300 million and 500 million people in the 20th century alone, originated in either India or Egypt at least 3,000 years ago. But it was not until the late 18th century that the English physician Edward Jenner vaccinated his first patient against the disease. It took another two centuries before smallpox was finally eradicated in 1980. Similar stories can be told about other killer diseases. The fate of humanity, our ancestors t...

Patent ductus arteriosus
Ductus arteriosus normally closes by 72 hours after birth. The structure becomes fibrotic later and remains as the ligamentum arteriosus. Endothelium of mature ductus responds to oxygen which acts as the stimulus of constriction as it receives oxygenated blood from the lungs. Premature ductus does not respond to oxygen that well. Patent ductus arteriosus is much more common in the premature infant than the mature infant. The higher the prematurity, the higher the chance of having a patent ductus arteriosus (PDA). PDA can occur as part of the congenital rubella syndrome. Patent ductus arteriosus – angio Patent ductus...

Congenital heart disease overview
Congenital heart disease can be broadly classified into cyanotic and acyanotic. Acyanotic congenital heart disease can be further subdivided into left to right shunts, obstructive lesions and a miscellaneous group. Cyanotic congenital heart disease can be classified into those with decreased pulmonary blood flow and those with reduced pulmonary blood flow. Left to right shunts include atrial septal defect, ventricular septal defect, patent ductus arteriosus and aortopulmonary window. One person can have more than one of these shunts. Large left right shunts can induce the development of pulmonary hypertension and lead to ...

General examination – eyes and facial dysmorphism
General examination – eyes and facial dysmorphism Clinically examination is guided by the symptoms. Unless the history is not correlated with findings, important diagnostic possibilities may be missed. Clinical examination starts off with a focused general examination followed by a detailed examination of the cardiovascular system. Relevant points in other systems like basal crepitations, hepatosplenomegaly and neurological deficits should be looked for. Examination strategy should be fitting to the clinical situation. When a patient presents to the emergency room, it should be a short but focused examination to perm...

Vaccines for COVID-19 moving closer
As the world reels from illnesses and deaths due to COVID-19, the race is on for a safe, effective, long-lasting vaccine to help the body block the novel coronavirus SARS-CoV-2. The three vaccine approaches discussed here are among the first to be tested clinically in the United States. How vaccines induce immunity: The starting line In 1796, in a pastoral corner of England, and during a far more feudal and ethically less enlightened time, Edward Jenner, an English country surgeon, inoculated James Phipps, his gardener’s eight-year-old son, with cowpox pustules obtained from the arm of a milkmaid. It was widely believed ...

Sunday Sermonette: The Diagnostic and Statistical Manual of Skin Diseases
For those who claim that the Bible is the literal and inerrant word of God, and who claim to live by the Bible, Leviticus 13 and 14 ought to pose a considerable problem. Of course nobody who makes that claim is sincere. They just skip the embarrassing parts. Noah ' s ark is a fun story with animals. You can build a theme park around it. These chapters, however, are just deeply weird.It ' s important to note that " leprosy " here does not mean the disease which has been given that name in modern times, now more properly called Hansen ' s Disease. None of the symptoms described here correspond to those of Hansen ' s disease,...

No Relationship Between Notifiable Diseases and Immigrant Populations
Alex Nowrasteh andAndrew C. ForresterThe international spread of the SARS ‐​CoV‐​2 virus that causes the disease COVID-19 has prompted many governments to close their borders. Immigration policy plays an important role in limiting the international spread of contagious diseases.Prior to the COVID-19 crisis,several commentators were concerned that immigrants – especially illegal immigrants – were spreading serious diseases in the United States. This blog post is the first in a series to answer the question of whether immigrants spread serious notifiable diseases other than COVID-19 in the United States. This ...

Why follow a vaccine schedule?
Right now, many people are hoping for a vaccine to protect against the new coronavirus. While that’s still on the horizon, new research suggests that families who do vaccinate their children may not be following the recommended schedule. Vaccines are given on a schedule for a reason: to protect children from vaccine-preventable disease. Experts designed the schedule so that children get protection when they need it — and the doses are timed so the vaccine itself can have the best effect. When parents don’t follow the schedule, their children may not be protected. And yet, many parents do not follow the schedule. A th...

The real cost, and longer term implications, of the Wuhan coronavirus
It ' s too soon to know for sure how the tale of the novel coronavirus will play out,but at this point we have a pretty good idea. A stipulation in both of the scenarios at the linked essay is that yeah, it gets loose into the wild and eventually can show up anywhere in the world. I think that ' s pretty much definitely going to happen if it hasn ' t already.Scenario number 1, and most likely, in my view, it will just be one more virus that causes what amounts to a common cold and in a few people who are otherwise debilitated goes on to be complicated by pneumonia. In that case, for a year or two it will circulate as a nov...
