This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as persistent ventricular fibrillation/tachycardia). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.

Worst Plantar Warts & Plantar Wart Removal
Worst Plantar Warts & Plantar Wart Removal samer kareem 60,106 Views • 3 years ago

Plantar warts are hard, grainy growths that usually appear on the heels or balls of your feet, areas that feel the most pressure. This pressure also may cause plantar warts to grow inward beneath a hard, thick layer of skin (callus). Plantar warts are caused by the human papillomavirus (HPV). The virus enters your body through tiny cuts, breaks or other weak spots on the bottom of your feet. Most plantar warts aren't a serious health concern and may not require treatment. But plantar warts can cause discomfort or pain. If self-care treatments for plantar warts don't work, you may want to see your doctor to have them removed.

Orchitis
Orchitis samer kareem 3,423 Views • 3 years ago

Orchitis (or-KIE-tis) is an inflammation of one or both testicles. It is usually caused by a bacterial infection or by the mumps virus. Bacterial orchitis can be caused by sexually transmitted infections (STIs), particularly gonorrhea or chlamydia. Bacterial orchitis often results from epididymitis, an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. In that case, it's called epididymo-orchitis. Orchitis causes pain and can affect fertility. Medication can treat the causes of bacterial orchitis and can ease some signs and symptoms of viral orchitis. But it may take several weeks for scrotal tenderness to disappear.

Hair Transplant Techniques: Difference between FUE vs FUT
Hair Transplant Techniques: Difference between FUE vs FUT Alicia Berger 3,174 Views • 3 years ago

Today, hair transplant physicians are able to make use of different techniques to extract and transplant large numbers of hair follicles (follicular units). There are two primary techniques for hair transplantation currently in use. The FUE (Follicular Unit Extraction) and the FUT (Follicular Unit Transplantation) methods. They differ primarily in the way hair follicles are extracted from the donor area. Follicular Unit Transplantation (FUT) The FUT process involves removing a small strip of tissue from the back of the head, from which the donor hair follicles will be extracted. The hair follicles are harvested from the strip by a skilled clinical team before being individually transplanted to the recipient areas. In most cases, and especially cases of advanced hair loss, FUT is the preferred method because it allows the physician to fully utilize the scalp area to deliver results consistent with patient expectations. FUT typically allows for the greatest number of grafts to be transplanted in a single session. Pain Management Some patients report higher levels of discomfort with FUT procedures compared to FUE due the potential swelling in the area where the strip of tissue was removed, but both methods have a very manageable recovery period and pain medication can be prescribed by your physician if needed. Both techniques of hair transplantation are relatively simple. Hair transplantation procedures are outpatient surgeries with some patients going back to work as soon as the very next day. Scarring The FUT strip extraction method typically results in a very narrow linear scar in the back of the head (typically 1mm in diameter or less in size). Since the scar is very thin, it’s easily concealed by all but the shortest of haircut styles. A short to moderate crop setting on most clippers is sufficient to conceal the scar for the majority of patients, and over time the scar will become less noticeable as it fades. Costs The industry norm for pricing is on a per-graft basis. This allows each individual to pay for only what they need and receive in number of grafts, and not a flat rate that in the end may cost you more. The per-graft cost of a FUT procedure is generally lower than that of a FUE procedure. Lately however, in response to the rising popularity of the FUE technique, many hair transplantation clinics have started lowering the per graft cost on FUE procedures, so that the cost difference between the two types of procedure are not as much as most people think. The costs of medical procedures always vary by patients’ conditions, needs and objectives. For the most accurate assessment of your hair loss and the associated cost of your hair restoration, you will need to speak to a physician. Follicular Unit Extraction (FUE) In an FUE hair transplantation, each follicular unit is individually taken directly from the scalp with no strip of tissue being removed. Hair follicles are removed in a random fashion and the result is less density in the donor area that many say is not even noticeable. This is the main difference between FUE & FUT. Since follicles are removed one at a time, fewer follicles can be harvested during a typical session, making FUE a better option to restore hair in smaller cases (number of grafts) compared to the traditional FUT method. FUE is constantly evolving and what was once utilized for only smaller cases is now being utilized for larger and larger cases. Some people that prefer the FUE method may have the option of splitting their procedure into two days in order to complete their recommended transplantation goals. Pain Management With no stitches required and no linear scar left to heal, FUE procedures do have a faster healing time and less post-procedure discomfort compared to the traditional FUT procedure. Scarring Since FUE procedures involve removing hairs individually from the scalp, there is no linear scar left behind. However, there will be tiny 1mm in diameter or less puncture marks that tend to heal by themselves after scabbing-over in the days following the procedure. These tiny wounds typically heal within three to seven days. Costs Since the physician must remove each hair follicle individually, the time-sensitive nature of an FUE procedure typically makes it more expensive than an FUT procedure. As stated earlier, FUE technology is improving as well as gaining popularity and many hair restoration practices (including Bosley) have started to lower the cost per graft price for FUE procedures. Nowadays, the cost difference between a FUE and a FUT procedures is less disparate.

Near the end of diastole, the ventricles nearly fill with blood, and then the atria contract, adding even more volume to the ventricles. The volume of blood in the ventricles at the end of diastole is referred to as the end-diastolic volume. The other phase of the cardiac cycle is called systole.

People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.

Open heart (coronary artery bypass, or CABG) surgery is performed in order to reroute, or "bypass," blood around blocked arteries, thereby improving the supply of oxygen-rich blood to the heart. Surgeons usually use an artery from the chest wall to construct the "detour" around the blocked part of the artery. Veins from the legs are also used.

interstitial cystitis
interstitial cystitis samer kareem 2,782 Views • 3 years ago

Interstitial cystitis is a clinical syndrome characterized by daytime and nighttime urinary frequency, urgency, and pelvic pain of unknown etiology. Interstitial cystitis has no clear etiology or pathophysiology, and diagnostic criteria for the syndrome remain undefined. Despite considerable research, universally effective treatments do not exist; therapy usually consists of various supportive, behavioral, and pharmacologic measures. Surgical intervention is rarely indicated. The International Continence Society has coined the term painful bladder syndrome (suprapubic pain with bladder filling associated with increased daytime and nighttime frequency, in the absence of proven urinary infection or other obvious pathology) and reserves the diagnosis of interstitial cystitis for patients with characteristic cystoscopic and histologic features of the condition.[1] An international consensus panel was able to generally agree on the following definition of interstitial cystitis/bladder pain syndrome (IC/BPS): unpleasant sensation (pain, pressure, discomfort) perceived to be related to the urinary bladder and associated with lower urinary tract symptoms of more than 6 weeks duration, in the absence of infection or other identifiable causes. American Urological Association (AUA) guidelines published in 2011 and amended in 2014 use an evidence-based approach to provide a clinical framework for the diagnosis and management of this condition.[2, 3, 4] In 1887, Skene initially described a condition characterized by inflammation that destroyed the urinary bladder "mucous membrane partly or wholly and extended to the muscular parietes." Guy Hunner popularized the disease with the description of characteristic bladder wall ulcers in association with a symptom complex of chronic bladder inflammation.[5] The first comprehensive epidemiologic description of interstitial cystitis is credited to Hand, who in 1949 described the widespread, small, submucosal bladder hemorrhages and the significant variation in bladder capacity characteristic of the condition. Despite years of intensive research, there are no specific clinical or urinary markers currently clinically available; no absolutely specific radiographic, laboratory, or serologic findings; and no biopsy patterns that are pathognomonic for interstitial cystitis. Some research suggests that the following may all play a role in the disease pathophysiology: (1) pelvic floor dyfunction, (2) dysregulated immune or inflammatory signals, (3) neural hypersensitivity, and (4) disruption of the proteoglycan/glycosaminoglycan (GAG) layer.[6] Interstitial cystitis, howerver, remains a diagnosis of exclusion (see Presentation, DDx, and Workup.) Intensive study has been done to attempt to identify biomarkers for IC/BPS. Some interesting studies have shown that bladder nitric oxide is an accurate marker for Hunner lesions, but these are not present in all patients, and the test requires specific equipment, which has limited widespread clinical use.[7] Differences in levels of cytokines and chemokines, specifically CXCL-10, have shown some ability to differentiate patients with and without Hunner lesions.[8] Other studies of ulcerative IC/BPS have shown that numerous other cytokines and chemokines are up-regulated as well, heralding a possible urinary test to identify patients.[9] An additional substance shown to be up-regulated in IC/BPS patients is antiproliferative factor (APF). This small 8–amino-acid peptide has been associated with suppression of cell growth, increases in transcellular permeability, and lowering of levels of proteins that form intercellular junctional complexes. It is synthesized and secreted from bladder epithelial cells from patients with IC/BPS and may play a key role in pathophysiology.[10] In vitro studies have shown that removal of APF from cell culture media restored cell proliferation and membrane integrity.[11] Studies have also suggested APF in the therapeutic effect of hydrodistension in patients with IC/BPS, although further confirmatory studies are necessary.[12] The most important element in treating patients with interstitial cystitis is education and emotional support. Periodic exacerbations are managed as they occur because no long-term therapy has been shown to prevent or delay recurrent episodes. Therefore, the purpose of treatment is to palliate and alleviate symptoms. Because no discrete pathognomonic pathologic criteria exist for assessing and monitoring disease severity, indications and goals for treatment are based on the degree of patient symptoms. Assessing patient response to treatment is also complicated because of the subjective nature of symptoms; the waxing and waning nature of symptoms without treatment; and the lack of objective serologic, physical, or histopathologic findings. Conservative measures and oral or intravesical treatments are considered first-line treatment. (See Treatment.)

Squamous Cell Carcinoma of Skin
Squamous Cell Carcinoma of Skin samer kareem 1,530 Views • 3 years ago

Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.

Both lower extremities must be evaluated to determine the presence or extent of any disease and to ascertain the pulse status of the patient. The feet are examined for signs of peripheral vascular disease and the anterior and posterior tibial pulses are palpated. Because an intact arch can supply retrograde flow to the major vessels of the foot, it can be helpful to put pressure on the anterior tibial artery when detecting the presence of a posterior tibial pulse and visa-versa. This "modified Allen's test" may detect proximal vessel obstruction masked by an intact foot arch. The need for preoperative angiography in young, healthy patients with a normal physical examination has been hotly debated. Our tendency has been to obtain preoperative angiograms as a guide. Although rare, we have seen lower extremities with a dominant peroneal artery nourishing the foot and distal anterior and posterior vessels, contraindicating sacrifice of the peroneal artery. MRI or CT angiography can also be used in many circumstances.
