Spider Veins – Cause and Treatments

Sometimes, you may have noticed red and blue blood vessels visible through your skin. Did you been a bit worried or embarrassed about them? Do you wonder what they are? They are known as spider veins. Let’s discuss the causes and various treatments of spider vein.

What causes spider veins?
Spider veins are a mild manifestation of venous reflux disease. This means a small, tangled groups of blood vessels that are found just under the surface of the skin. The veins are slightly dilated, and have the appearance of spider webs or branches, and usually occur spread out around the legs and feet.

What are the risk factors?
Spider vein risk factors are similar to those associated with varicose veins, including advancing age, obesity, occupations requiring extended periods of standing, heredity factors and hormonal changes. People can also develop this condition due to prolonged exposure to ultraviolet rays or as a result of weak vessel walls.

From the risk factors, it is clear that some people are prone to this problem than others. For example, if you work as a surgeon, a nurse or a teacher, chances are higher that you could suffer from this condition. Similarly, for people with a genetic history of weak vein valves, the probability of developing spider veins is also high. The same applies to hormonal changes, which mainly occur during puberty, pregnancy and menopause.

The exact cause of spider veins is yet to be established. Existing risk factors can be divided into two wide sub-divisions, i.e. congenital causes and acquired causes. In congenital causes, is port-wine stain, Maffucci’s syndrome and hereditary hemorrhagic telangiectasia (also known as osler-weber-rendu syndrome), among others. The acquired causes include chemotherapy, acne rosacea and lifestyle/occupation risk factors (as mentioned above).

Spider vein symptoms
Spider veins are painful in some cases, with cramping and aching. They often result in a feeling of heaviness in the legs, and burning, throbbing or tingling sensations. Also, other symptoms such as swelling, fatigue and itching can also be experienced. In advanced cases, this condition can establish ulcers, large sores and phlebitis. However, spider veins are noticed by their appearance in a majority of incidences.

Tests and Diagnosis
Doctors usually employ non-invasive diagnostic tests to diagnose this condition. These tests are perfectly safe and painless, with no scalpels, needles or medication needing to be involved. The entire procedure is normally very brief, and generally won’t take you more than an hour from start to finish.

There are three main things that doctors seek to answer through these diagnostic tests. First, they are seeking to establish any evidence of deep vein blood clots. Secondly, they ascertain if the veins are functioning properly. And last, they test the Greater Saphenous Vein (GSV) to determine if it is working well or not.

Any competent vein specialist will always undertake this exercise before treating your condition. Some of the procedures that you can expect include:

*Color-flow Duplex Exam – This is used to evaluate the anatomy of the affected veins. It determines the direction of blood flow, openings and blockages. This procedure is also important in the process of vein mapping (done for skin deep problems).

*Bi-directional Doppler Exam – This is an ultrasound exam used to determine the speed of blood flow and whether it pauses during normal breathing. It also identifies whether the veins are working properly.

*Photoplethysmography – Phew! Don’t let this complicated medical word intimidate you. Photoplethysmography is basically a diagnostic procedure that is used to determine the efficiency of your calf muscle pump.

*Pressure Calf Exam – In performing this exam, you’ll be asked to lie facing upwards with legs lifted higher than your chest. This diagnostic procedure seeks to identify any vessel blockages.

Treatment
After establishing the nature of your problem, the doctor can then outline the best treatment for you. Here are several available options:

Sclerotherapy
This procedure involves the doctor injecting a saline solution into the affected veins. The solution results in damage to the affected vessel walls, causing them to swell and seal shut. Eventually the scar tissue will fade away. The sclerotherapy procedure takes approximately thirty minutes, and has only mild side-effects. Though the injection may be a bit painful, the stinging sensation is usually gone within a few minutes.

Laser and Intense Pulsed Light
This treatment option employs the use of a specialized device that focuses laser energy to the affected tissue. The procedure only takes twenty minutes, and has minimal side-effects.

Natural Remedies
Using natural remedies can mean the difference between undergoing medical procedures or not, and are valuable alongside medical treatment. Some recommended herbal remedies include:

*Horse Chestnut Seed – Studies show that this seed helps to improve blood circulation in the legs thus strengthening the veins and capillaries.

*Bilberry Extract – This herbal extract is known to stimulate new capillary formation thus strengthening the capillary walls.

*Butchers Broom – This herb strengthens veins.

*Gotu Kola – A very effective extract which addresses venous insufficiency, foot swelling and water retention. It therefore provides a good solution to spider veins found on the legs.

*Distilled Witch Hazel – This is directly applied on the affected areas using a cotton ball. Numerous clinical studies show that this extract can help strengthen blood vessels.

Caution: For health safety purposes, do not start using any herbal remedies without consulting a qualified doctor.

Spider veins prevention
Two of the most important things regarding the prevention of spider veins are eating a balanced diet and getting regular exercise. Eating a diet higher in fresh, raw fruits and vegetables than meat and convenience food is very important, and if your job requires you to stand for a long time, you should regularly shift your body weight from one leg to another as well as standing evenly balanced.

To sum things up, the procedure of a spider vein removal is chosen by several key factors. Your specialist will determine the best treatment options based on the results obtained from the diagnostic tests. We hope that this article will provide all the necessary guidance you need in addressing this problem.

Metal Fabrication – History and Use in Mining Industry

Metal fabrication began in the earliest civilizations when the metals gold, mercury, silver, tin, iron, lead, and copper were discovered. These metals were worked by early artisans into decorative pieces, religious iconography, and jewelry. Items of a practical nature were forged from metal including coinage, tools, and weapons. Using heat and tools, metalworkers began to make functional objects and the industry developed through the years advancing and gaining value from society.

As an industrialised society, the world cannot live without metal; it is essential to almost every industry from mining and heavy industry to agriculture and medical equipment.

Specialist engineers and manufacturers fabricate metal and metal alloys, which are made from a combination of different metals for a staggering number of uses. The pivotal role of metal has been responsible for significant advances in technology, construction, transport, and agri-science. Metal has strength; it is very low maintenance and will last a lifetime and more. Specialist metal fabrication companies are made up of a group of skilled people who all have a role in the process of turning metal into supports for a building, heavy duty mining equipment or boilers and tanks to name a few.

Metal fabrication is a series of processes used to manufacture an object from metal. The specialised equipment involved includes laser cutting machinery, turret punches, machine centers, rollers, welding machinery, water jets, and metal shears. The metals most commonly used for fabrication are aluminium, stainless steel, and carbon steel, which is in the form of sheets, tubing and bars. Most metal objects start life as sheet metal in varying thicknesses depending on the application. Thicker sheets are known as metal plate.

The process starts with the design and then the fabrication begins with the metal sheet being sheared, laser cut or punched into shapes. Once the required basic shape is achieved, the object goes next to the press brake machine to form any bends a process known as forming. Dies are used in the press brake to make the correct accurate shape according to the design plans. The product may be finished at this stage or will be just one component in a series that requires moving on to the next process, which is welding.

Welding is a skilled practice and the artistry of the welder is to take the component parts shaped and formed previously and weld all the pieces together to make the final product in accordance with the design. This final assembly is critical and it is up to the welder to use the welding technique necessary for the job in hand.

Metal fabrication is essential to heavy industry such as mining. The manufacturing of support equipment, skids, conveyor belts, tanks, crushers, drill rigs and hydraulic lifting equipment through to pipe work are all the result of the metal fabrication process. In the mining industry there are very often special requests for one off pieces of equipment that are needed in a hurry and the metal fabrication business that can design and manufacture the product to implementation on site is the company that has the advantage. Metal fabricators may also be called upon to repair equipment or weld a broken object. Mining relies upon rugged, tough machinery often needing custom manufacturing or enhancements making metal fabricators an essential support service to the industry.

Reputable metal fabricators have the ability to design high quality, complex products with precision and manufacture them to full compliance with the specification, which is essential to mining companies who need to be operational at all times. Other metal fabrications for the mining industry include chutes, bins, screen stands, safety guards, stairs, catwalks, platforms and wear plates.

Metal is an essential material for mankind and industry and has the ability to be recycled over and over again which makes it a valuable resource for the global environment. The long working life of all metal fabrications due to its durability means once your product is manufactured, you will not have to worry about it, as it is highly unlikely it will need your attention again.

The mining industry is reliant upon the equipment and the expertise of metal fabricators not only for mine construction but also for ongoing support and maintenance in such rugged environments. For metal fabrication Mackay or metal repairs Mackay, contact 3D Engineering Mackay today.

Shrink Wrap Film – Presentsation Counts

Manufacturers across the divide continue to produce quality products. We are all too familiar, with the attractive transparent packaging of toys, imported fruits, clothes, pens amongst other things. Unlike the previous times, customers can still have a glimpse into their prospective purchases, carefully examining them without necessarily compromising their state or quality (food).

It is of note that, both polymers are ideal for different packaging purposes. The choice of shrink film is determined by the product, budget and level of technology the producer in question has.

The undeniable fact is, packaging being the cornerstone of branding and advertising can be responsible for high sales volume or the reverse. Manufacturers and producers alike are today faced with the tough task of choosing the ideal packaging material. In the end the functionality of the shrink wrap can only be determined by the manufactures and producers.

It is as a result of these demands that the skrink wrap film was developed. In the formative years; we were all accustomed to the brown paper bags which had our tree population on the decline. Subsequent move to the opaque store-name-christened polythene was a further disservice. Then came the perfect solution to all these problems, the shrink film.Initially, the shrink film was exclusively made from PVC (Polyvinylchloride).This is a plastic polymer (third most used plastic in the world) that had the capability of sealing products with a thin layer of plastic sheet. These sheets were often transparent to allow the customer have a view of the product.

The sheet would be wrapped over the product and passed over a heat tunnel or a heat gun. Normally, the length or circumference of the product would be measured, 10% of this value would be added then the sum is divided by two, this would give the size of PVC shrink wrapping to be used. PVC has the ability to shrink by 40% percent giving the packaging a tight grip of the product.

However, with time it was noticed that PVC could release small amounts of hydrogen chloride giving the products a characteristic smell in addition to poisoning. The sealers also would have small carbon deposits. The presence of a plasticizer in PVC had the drawback of hardening and shrinkage during cold weather and extreme stetching with subsequent temperature increases.

These drawbacks meant a suitable shrink film devoid of a plasticizer be developed. Polyolefin was found to have the packaging abilities of PVC but lacked the setbacks that faced the latter. It became a preferred choice of packaging. Offering a stronger seal and fewer odours. Its lack of plasticizer meant no physical changes to the shrink film. It would become the perfect storage solution; all weather .Lack of chlorine in its polymer meant no hydrogen chloride previously characteristic of PVC.

However, while its predecessor PVC enjoys machine compatibility and low cost purchases, polyolefin is the opposite, it remains relatively expensive and hard to use alongside machines.PVC on the other hand remains a suitable choice for manufacturers who don’t deal with edible products. Owing to its cheap price and machine compatibility it is a manufacturers darling.
