Low Thyroid - Could It Be A T3 Problem?
Low Thyroid - Could It Be A T3 Problem? samer kareem 5,807 Views • 2 years ago

NTIS refers to a syndrome found in seriously ill or starving patients with low fT3, usually elevated RT3, normal or low TSH, and if prolonged, low fT4. It is found in a high proportion of patients in the ICU setting, and correlates with a poor prognosis if TT4 is <4ug/dl. The patho-physiology includes suppression of TRH release, reducedT3 and T4 turnover, reduction in liver generation of T3, increased formation of RT3, and tissue specific down-regulation of deiodinases, transporters, and TH receptors. Although long debated, tissue TH levels are definitely reduced, and tissue hypothyroidism is presumably present. This is often not clinically evident because of the brief duration, and reduced but not absent tissue levels of TH. Although recognized for nearly 4 decades, interpretation of the syndrome is contested, because of lack of data. Some observes, totally without data, argue that it is a protective response and should not be treated. Other observers (as in this review) present available data suggesting, but not proving, that thyroid hormone replacement is appropriate, not harmful, and may be beneficial. The best form of treatment (TRH,TSH,or T3+T4) and possible accompanying treatments (GHRH, Cortisol, nutrition, insulin) lack consensus. In this review current data are laid out for reader’s review and judgment.

Aspirin fights against cancer
Aspirin fights against cancer Doctor 7,390 Views • 2 years ago

A new well designed randomized study has suggested that long term baby aspirin usage may aid in fight against cancer. The suggested mechanism is that cancers induce inflammatory responses so the anti-inflammatory mechanism of prostaglandins inhibitors may cease the progress of many cancers. There are some concerns about the study because despite the well-designed randomized study; the study didn't include a satisfying number of female participants. The study was also conducted on esophageal, colorectal and lung cancers.

Amyotrophic lateral sclerosis 3D Animation
Amyotrophic lateral sclerosis 3D Animation Mohamed 15,392 Views • 2 years ago

Amyotrophic lateral sclerosis The disorder causes muscle weakness and atrophy throughout the body caused by degeneration of the upper and lower motor neurons. Unable to function, the muscles weaken and atrophy. Affected individuals may ultimately lose the ability to initiate and control all voluntary movement, although bladder and bowel sphincters and the muscles responsible for eye movement are usually, but not always, spared. Cognitive function is generally spared for most patients although some (~5%) also have frontotemporal dementia.A higher proportion of patients (~30-50%) also have more subtle cognitive changes which may go unnoticed but are revealed by detailed neuropsychological testing. Sensory nerves and the autonomic nervous system, which controls functions like sweating, are generally unaffected but may be involved for some patients. The earliest symptoms of ALS are typically obvious weakness and/or muscle atrophy. Other presenting symptoms include muscle fasciculation (twitching), cramping, or stiffness of affected muscles; muscle weakness affecting an arm or a leg; and/or slurred and nasal speech. The parts of the body affected by early symptoms of ALS depend on which motor neurons in the body are damaged first. About 75% of people contracting the disease experience "limb onset" ALS i.e. first symptoms in the arms ("upper limb", not to be confused with "upper motor neuron") or legs ("lower limb", not to be confused with "lower motor neuron"). Patients with the leg onset form may experience awkwardness when walking or running or notice that they are tripping or stumbling, often with a "dropped foot" which drags along the ground. Arm-onset patients may experience difficulty with tasks requiring manual dexterity such as buttoning a shirt, writing, or turning a key in a lock. Occasionally, the symptoms remain confined to one limb for a long period of time or for the whole course of the illness; this is known as monomelic amyotrophy. About 25% of cases are "bulbar onset" ALS. These patients first notice difficulty speaking clearly or swallowing. Speech may become slurred, nasal in character, or quieter. Other symptoms include difficulty swallowing, and loss of tongue mobility. A smaller proportion of patients experience "respiratory onset" ALS where the intercostal muscles that support breathing are affected first. Regardless of the part of the body first affected by the disease, muscle weakness and atrophy spread to other parts of the body as the disease progresses. Patients experience increasing difficulty moving, swallowing (dysphagia), and speaking or forming words (dysarthria). Symptoms of upper motor neuron involvement include tight and stiff muscles (spasticity) and exaggerated reflexes (hyperreflexia) including an overactive gag reflex. An abnormal reflex commonly called Babinski's sign (the big toe extends upward and other toes spread out) also indicates upper motor neuron damage. Symptoms of lower motor neuron degeneration include muscle weakness and atrophy, muscle cramps, and fleeting twitches of muscles that can be seen under the skin (fasciculations). Around 15–45% of patients experience pseudobulbar affect, also known as "emotional lability", which consists of uncontrollable laughter, crying or smiling, attributable to degeneration of bulbar upper motor neurons resulting in exaggeration of motor expressions of emotion.

To avoid pregnancy and STDs, always remember to use a condom every time you have sex — including oral, vaginal, or anal sex. Whenever oral sex is being performed on a girl, a dental dam should be used. A guy receiving oral sex should wear a latex condom — or, if he or his partner is allergic to latex, a polyurethane condom.

Laparoscopically Assisted Vaginal Hysterectomy samer kareem 2,852 Views • 2 years ago

procedure is usually done in the hospital or outpatient surgical center under general anesthesia (while you are asleep and pain-free). The procedure is performed in the following way: The surgeon makes a small cut (incision) below the belly button (navel). A needle or tube is inserted into the incision. Carbon dioxide gas is passed into the abdomen through the needle or tube. The gas helps expand the area, giving the surgeon more room to work, and helping the surgeon see the organs more clearly. A tube is placed through the cut in your abdomen. A tiny video camera (laparoscope) goes through this tube and is used to see the inside of your pelvis and abdomen. More small cuts may be made if other instruments are needed to get a better view of certain organs. If you are having gynecologic laparoscopy, dye may be injected into your cervix area so the surgeon can view your fallopian tubes. After the exam, the gas, laparoscope, and instruments are removed, and the cuts are closed. You will have bandages over those areas.

Amnesia
Amnesia samer kareem 5,655 Views • 2 years ago

Amnesia refers to the loss of memories, such as facts, information and experiences. Though having no sense of who you are is a common plot device in movies and television, real-life amnesia generally doesn't cause a loss of self-identity. Instead, people with amnesia — also called amnestic syndrome — are usually lucid and know who they are, but may have trouble learning new information and forming new memories. Amnesia can be caused by damage to areas of the brain that are vital for memory processing. Unlike a temporary episode of memory loss (transient global amnesia), amnesia can be permanent. There's no specific treatment for amnesia, but techniques for enhancing memory and psychological support can help people with amnesia and their families cope.

Bartter vs Gitelman syndrome samer kareem 1,816 Views • 2 years ago

Bartter syndrome has traditionally been classified into three main clinical variants, as follows: Neonatal (or antenatal) Bartter syndrome Classic Bartter syndrome Gitelman syndrome Advances in molecular diagnostics have revealed that Bartter syndrome results from mutations in numerous genes that affect the function of ion channels and transporters that normally mediate transepithelial salt reabsorption in the distal nephron segments. Hundreds of mutations have been identified to date. Such advances may result in the development of new therapies (see the image below). [2] (See Pathophysiology and Etiology.)

Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.

Aneurysm Clipping
Aneurysm Clipping samer kareem 2,029 Views • 2 years ago

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.

First aid steps to help stop or shorten a seizure or prevent an emergency situation. This may involve giving a rescue treatment (often called "as needed" medicine or treatment) that has been recommended by your health care team. The rescue treatments described here can be given by non-medical people who are not in a hospital setting. They are intended for use by anyone (the person with seizures, family member or other observer) who has been trained in their use. These therapies can be given anywhere in the community
