Better Vein Care and Safer Injection

In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.

Blind loop syndrome (BLS), commonly referred to in the literature as small intestinal bacterial overgrowth (SIBO) or bacterial overgrowth syndrome (BOS), is a state that occurs when the normal bacterial flora of the small intestine proliferates to numbers that cause significant derangement to the normal physiological ...

Gallstone ileus is an important, though infrequent, cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by impaction of a gallstone in the ileum after being passed through a biliary-enteric fistula. The diagnosis is often delayed since symptoms may be intermittent and investigations fail to identify the cause of the obstruction. The mainstay of treatment is removal of the obstructing stone after resuscitating the patient. Gallstone ileus continues to be associated with relatively high rates of morbidity and mortality.

Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a woman's uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.

Epidermoid cysts, also called sebaceous, keratin, or epithelial cysts, are small, hard lumps that develop under the skin. These cysts are common. They grow slowly. They do not cause other symptoms and are nearly never cancerous. Epidermoid cysts are often found on the face, head, neck, back, or genitals

Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.

Retropharyngeal abscess (RPA) produces the symptoms of sore throat, fever, neck stiffness, and stridor. RPA occurs less commonly today than in the past because of the widespread use of antibiotics for suppurative upper respiratory infections. The incidence of RPA in the United States is rising, however. Once almost exclusively a disease of children, RPA is observed with increasing frequency in adults. It poses a diagnostic challenge for the emergency physician because of its infrequent occurrence and variable presentation.

A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include

What Is a Hair Transplant? It's a type of surgery that moves hair you already have to fill an area with thin or no hair. Doctors have been doing these transplants in the U.S. since the 1950s, but techniques have changed a lot in recent years. You usually have the procedure in the doctor's office. First, the surgeon cleans your scalp and injects medicine to numb the back of your head. Your doctor will choose one of two methods for the transplant: follicular unit strip surgery (FUSS) or follicular unit extraction (FUE). With FUSS, the surgeon removes a 6- to 10-inch strip of skin from the back of your head. He sets it aside and sews the scalp closed. This area is immediately hidden by the hair around it. Next, the surgeon’s team divides the strip of removed scalp into 500 to 2,000 tiny grafts, each with an individual hair or just a few hairs. The number and type of graft you get depends on your hair type, quality, color, and the size of the area where you’re getting the transplant. If you’re getting the FUE procedure, the surgeon’s team will shave the back of your scalp. Then, the doctor will remove hair follicles one by one from there. The area heals with small dots, which your existing hair will cover. After that point, both procedures are the same. After he prepares the grafts, the surgeon cleans and numbs the area where the hair will go, creates holes or slits with a scalpel or needle, and delicately places each graft in one of the holes. He’ll probably get help from other team members to plant the grafts, too. Depending on the size of the transplant you’re getting, the process will take about 4 to 8 hours. You might need another procedure later on if you continue to lose hair or decide you want thicker hair. Expectations and Recovery After the surgery, your scalp may be very tender. You may need to take pain medications for several days. Your surgeon will have you wear bandages over your scalp for at least a day or two. He may also prescribe an antibiotic or an anti-inflammatory drug for you to take for several days. Most people are able to return to work 2 to 5 days after the operation. Within 2 to 3 weeks after surgery, the transplanted hair will fall out, but you should start to notice new growth within a few months. Most people will see 60% of new hair growth after 6 to 9 months. Some surgeons prescribe the hair-growing drug minoxidil (Rogaine) to improve hair growth after transplantation, but it’s not clear how well it works. Risks and Costs of Treatment The price of a hair transplant will depend largely on the amount of hair you’re moving, but it generally ranges from $4,000 to $15,000. Most insurance plans don’t cover it.

The term subclavian steal describes retrograde blood flow in the vertebral artery associated with proximal ipsilateral subclavian artery stenosis or occlusion, usually in the setting of subclavian artery occlusion or stenosis proximal to the origin of the vertebral artery. Alternatively, innominate artery disease has also been associated with retrograde flow in the ipsilateral vertebral artery, particularly where the subclavian artery origin is involved. Subclavian steal is frequently asymptomatic and may be discovered incidentally on ultrasound or angiographic examination for other indications, or it may be prompted by a clinical examination finding of reduced unilateral upper limb pulse or blood pressure. In some cases, patients may develop upper limb ischemic symptoms due to reduced arterial flow in the setting of subclavian artery occlusion, or they may develop neurologic symptoms due to posterior circulation ischemia associated with exercise of the ipsilateral arm.[1] Treatment has traditionally consisted of open subclavian artery revascularization, typically via carotid-subclavian bypass or subclavian artery transposition, which are generally durable procedures. Newer, less invasive options include endovascular intervention with recanalization as appropriate and angioplasty and stenting if required. The clinical relevance of subclavian steal was described in 1961 by Reivich, Holling and Roberts; however, the recognition of retrograde vertebral artery flow dates back another 100 years to Harrison and Smyth. Some papers, including a previous version of this article, advocate restricting the term subclavian steal to patients with neurologic symptoms only, but this is incorrect in view of the substantial literature using this term to describe the hemodynamic scenario of retrograde vertebral flow and proximal subclavian artery disease.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.
