Basics of Echocardiography
Transcript of the video: Echocardiography is now not restricted to the echocardiographic laboratory. It is used in the emergency department, at bedside, in the intensive care unit as well as in the operating room. Hence a basic knowledge is needed for all physicians and paramedics. During echocardiography, a transducer transmits the ultrasound beam towards the heart. Echoes received by the transducer from various structures of the heart are analysed by the echocardiograph and a graphical representation
displayed on the monitor.
Location of the transducer is at the top of the image sector. Structures nearer to the tr...

The shifting landscape of gastroenterology manpower and compensation
The field of gastroenterology in the United States has undergone a significant transformation over the past 5 to 10 years, driven by a confluence of historical changes in training programs, changing demographics among GI doctors due to the relatively new specialty of GI endoscopy, and a dwindling supply of gastroenterologists. These factors have culminated in

Video Capsule Navigates the Stomach
Researchers at George Washington University have created a swallowable capsule containing a video camera that can assist in identifying lesions in the stomach. However, unlike similar devices that have been developed previously, this capsule can drive around the stomach under the control of a clinician. This allows it to thoroughly navigate and screen the entire area to identify any health issues in the stomach mucosa, such as ulcers or bleeding. The technology requires an external magnet to be placed near the stomach, and the clinician can use a joystick, just like with a video game, to control the movement of the capsule...

Rapid Diagnosis: Vomiting Blood
The dispatcher reports that the patient is vomiting blood. Hemataemesis if you want to be technical about it. It could be a whole bunch of things right? … Well yes it could. Before you e-mail me to say that you can’t believe I missed Bolivian Hemorrhagic Fever, here’s one web site that lists 113 possibilities.
But if you want to play the numbers, it’s going to be one of four things. And if you want to play “stump your partner” you can narrow it down quite a bit based on your patients age and disposition.
There are four things that tend to cause a person to vomit blood. Before you click on the little ...

You ’re a doctor when you’re not giving anesthesia?
One recent afternoon in the GI endoscopy suite (not my favorite place to work, but that ’s a topic for another day), I walked up to the bedside of my next patient and introduced myself as I always do. “Hi,” I said, holding up my name badge for the patient and his wife to see. “I’mRead more …You ’re a doctor when you’re not giving anesthesia? originally appeared inKevinMD.com.

A man in his 60s woken from sleep by epigastric pain. Would you have been able to correctly diagnose him?
Written by Pendell MeyersA man in his mid 60s with history of CAD and stents experienced sudden onset epigastric abdominal pain radiating up into his chest at home, waking him from sleep. He called EMS who brought him to the ED. He had active chest pain at the time of triage at 0137 at night, with this triage ECG:I sent this ECG, without any text at all, to Dr. Smith, and he replied: " LAD OMI with low certainty. V3 is the one that is convincing. " After his response I sent him the baseline ECG (below), still with no context at all except that this was his prior ECG:Dr. Smith replied: " Now high certainty. By the way,...

A Man With Sudden Onset of Gastroparesis
By HANS DUVEFELT
Leo Dufour is not a diabetic. He is in his mid 50s, a light smoker with hypertension and a known hiatal hernia. He has had occasional heartburn and has taken famotidine for a few years along with his blood pressure and cholesterol pills.
Over the past few months, he started to experience a lot more heartburn, belching and bloating. Adding pantoprazole did nothing for him. I referred him to a local surgeon who did an upper endoscopy. This did not reveal much, except some retained food in his stomach. A gastric emptying study showed severe gastroparesis.
The surgeon offered him a trial of metoclopra...

Is IBD an underrecognized health problem in minority groups?
As many people know, inflammatory bowel disease (IBD) is a complex condition affecting the intestine, which is the part of the digestive tract that helps digest food and remove water, salt, and waste.
But you might not know this: in recent years in the US, IBD is being diagnosed more often among people who are Black, Hispanic/Latinx, East and Southeast Asian, or from other minority groups than it was in past decades.
Is this a true rise in cases? Is IBD underrecognized in minority populations? While we don’t have all the answers yet, exploring health disparities in IBD and explaining its symptoms may encourage more peopl...

Functional dyspepsia: Causes, treatments, and new directions
Functional dyspepsia (FD) is a common condition, loosely defined by some physicians as a stomach ache without a clear cause. More specifically, it is characterized by the feeling of fullness during or after a meal, or a burning sensation in the mid-upper abdomen, just below the rib cage (not necessarily associated with meals). The symptoms can be severe enough to interfere with finishing meals or participating in regular daily activities.
Those with FD often go through multiple tests like upper endoscopy, CT scan, and gastric emptying study. But despite often-severe symptoms, no clear cause (such as cancer, ulcer disease, ...

Gastrointestinal Diseases in America: The Costly Impact on Employers and Patients
SPONSORED POST
By SAM HOLLIDAY
Medically reviewed by Jenny Blair, MD
Gastrointestinal diseases like inflammatory bowel disease (IBD), gastroesophageal reflux disease (GERD), and irritable bowel syndrome (IBS) are more prevalent—and costlier—than many employers realize. Up to 70 million Americans are affected by gastrointestinal (GI) diseases each year—twice as many people as those living with diabetes (34.2 million).[1],[2] Overall direct healthcare costs for GI diseases are estimated to be $136 billion each year in the U.S., more than heart disease ($113bn) and mental health disorders ($99bn) [Figure 1]...

PENTAX Releases IMAGINA LED Powered Endoscopy System
PENTAX is releasing its IMAGINA Endoscopy System in the U.S., having just received FDA clearance for the GI imaging platform.
The endoscope sports two powerful and long lasting LEDs at the tip that do not require regular replacement, unlike traditional bulbs that can be costly to regularly swap for new ones. Given enough procedures, a clinic can end up saving significant amounts by using the IMAGINA over a system containing conventional bulbs. The system also features a HD+ CMOS light sensor and a touchscreen display on the control unit with 1080p resolution.
A combination of high end illumination with high resoluti...

Eosinophilic esophagitis: A new food-related allergic condition on the rise?
In the early 1990s, doctors began describing a new condition affecting the esophagus of patients who were predisposed to allergies including food allergy, asthma, and eczema, and who were having trouble swallowing. Today, we call this condition eosinophilic esophagitis (EoE).
What is EoE?
EoE is an allergic inflammation of the esophagus that causes a range of symptoms. Adolescents and adults most often experience it as difficulty swallowing, sometimes feeling like food moves too slowly through the esophagus and into the stomach. In some cases, food actually gets stuck (and may require urgent removal). Children and some adu...

Electronic Pill Popping to Detect GI Bleeds: Interview With EnteraSense
Getting a clear view of your GI tract typically involves the uncomfortable process of having a long endoscope snaked down the esophagus. Thankfully, capsule endoscopy technology is replacing many procedures that have required an endoscope. These swallow-able devices are able to withstand the harsh, acidic environment of the gut, and can provide high-resolution images, as well as temperature, pH, and pressure data.
EnteraSense, an early-stage startup based in Galway, Ireland, has developed a device that utilizes the “Pill Cam” form factor to detect upper GI bleeds. The technology is elegant, but challenging, ...
