The Primarily application of Ophthalmic Surgical Microscope
Surgical Microscopes have been introduced recently and they are one the advances in medicine. The leica microscopes are a head mounted microscopes. Most people would think of being used in medicine but this is not a regular microscope. To have a magnified view from all sides and inside the area the head gear allows the surgeon.
With magnification capabilities that can be used for surgeries, this is an apparatus that is worn on the head and has flexible properties and loupes. When used for invasive procedures and for the most serious procedures including delicate paediatric surgeries, this head gear offers sharp 3D images. One of the essential tools that surgeons are depending on more and more for vascular, cardio and thoracic surgeries is the Leica microscope that is head mounted. In plastic surgery, reconstructive and cosmetic surgeries this tool is frequently used and more importantly this is one of the tools that is being used in paediatric surgeries. In orthopaedic, spinal, urology, as well as general and trauma surgeries, Medical head gear-the surgical microscope is utilized. For these types of surgeries and for the surgeon performing delicate procedures, this is become one of the most important tools.
Ophthalmic surgical microscopes are primarily used for or ophthalmology and ophthalmic eye surgery. The full motorization of the controls and the zoom magnification are the main features of these surgical microscopes. The foot and hand controls the motors. The surgeon can rotate the main head to convenient angle.
Binocular is the main head and another binocular is the assistant head but it is not tilt able and is on a fixed angle. The whole head assembly is rotated by one of the motorized functions on an angle.
By moving the whole head assembly on an X - Y grid, the other motorized function locates the specimen in the viewing optics. In the field of view, this motor centres the specimen. The zoom magnification is operated by another motorized function. The assistant's binocular head has a three step magnification allowing different powers to be seen as desired. Zoom optics are not found in the assistant head. It must be manually selected between the three magnifications.
For reduction in lens aberration, the lens is made from high quality imported German glass. All optics is multi-coated and includes mildew-proof and antireflection coatings. An extra monocular teaching tube is a useful option allowing a third observer to view the surgery simultaneously. This ophthalmic surgical microscope is made in a US FDA registered manufacturing facility as well as has CE certification.

Genital Warts Signs And after that Therapy
Genital warts, induced by some kinds of HPV(human papilloma virus) , can appear on your skin anywhere in the genital area as white or flesh- colored, smooth, small bumps, or larger, fleshy, cauliflower- like lumps. You can find more than 100 different subtypes of HPV, and around 30 of them specifically affect the genitals. Other HPV subtypes cause warts to grow on different parts of the body, such as the hands.
Certainly not everyone infected with HPV will develop genital warts. Some will be infected with a strain that does not produce warts, or they will remain asymptomatic(i. e. no warts will appear) even though the virus is present in the skin or mucous membranes around the genital area or on the cervix in women. Those who do go on to develop warts will usually notice them 1 to 3 months following initial infection.
If genital warts symptoms do arise then the infected person may notice pinkish/white small lumps or larger cauliflower- shaped lumps on the genital area. Warts can appear on or around the penis, the scrotum, the thighs or the anus. In women warts can develop around the vulva or inside the vagina and on the cervix. Whenever a woman has warts upon her cervix, this may cause slight bleeding or, very rarely, an unusual colored vaginal discharge.
Warts might occur singly or in groups. The warts may itch, but they are usually painless. Sometimes the warts are often difficult to spot. In severe cases, it is possible for warts to spread from the genitals to the area around the anus, even if anal intercourse has not occurred.
Sometimes, people can confuse skin problems caused by other STDs(such as genital herpes, syphilis or molluscum) with genital warts. Others may become very worried because they mistake perfectly normal and non- infectious lumps and bumps for genital warts.
Ailments that may be confused with genital warts include:
Pearly penile papules- tiny white or skin- colored bumps that, when numerous, appear in a ring around the edge of the head of the penis.
More rarely, similar papules may be found on the vulva.
Angiokeratomas- vivid red or purple spots that look slightly like blood blisters.
Sebaceous glands(furthermore known as 'Fordyce spots') - hard white, yellowish or skin- colored little bumps that may be found all over the skin of the penis and scrotum in men, and the vulva in women. Sebaceous glands produce a substance called sebum, which keeps the skin healthy.
Pimples or spots- caused by blocked sebaceous glands, pimples and spots can form just as easily around the genital area as they do on the face, and may become sore and inflamed in a similar way.
All of the above are common, non- infectious skin manifestations which are not sexually transmitted.
Some doubt about lumps and bumps on the genitals can usually be resolved by a quick visit to a doctor or sexual health clinic.
Genital HPV is transmitted through genital skin- to- skin contact, or through the transfer of infected genital fluids. This is usually during vaginal or anal sex, but it is also possible to pass it on through non- penetrative sexual activity.
In extraordinary circumstances, a woman can pass HPV on to her baby during vaginal childbirth.
A medical doctor or nurse can usually tell whether you have genital warts just by looking closely at the affected area. If warts are suspected but are not obvious, the doctor may apply a weak vinegar- like solution to the genital area; this turns any warts white and therefore makes them more visible.
In order to check for hidden warts, the doctor may carry out an internal examination of the vagina, cervix as well as/or anus.
If a person suspects they have been exposed to HPV, but does not yet have symptoms, their doctor may be able to take a swab to test for high- risk strains of the virus(this isn't available in all countries) . In women, this may be performed alongside a cervical Pap smear test.
Not everyone diagnosed with HPV will develop warts, and patients may be asked to come back for another examination at a later date if nothing is yet visible.
In case you have any symptoms or you are worried you may have been infected with an STD, you should talk about your worries with a doctor. They may be able to run tests or offer you treatment themselves, or refer you on to someone who can.
There is no treatment that can completely eliminate genital warts once a person has been infected. Often outbreaks of genital warts will become less frequent over time, until the body naturally clears the virus and the warts disappear of their own accord. However, in some people the infection may linger.
Any doctor can give patients various treatments to clear genital warts, but they may reappear even after treatment. A virus, not a bacterium, causes genital warts so antibiotics will not get rid of them. Common treatments include:
Podophyllin resin – a brown liquid which is painted on to the wart(s) by a doctor or nurse and must be washed off 4 hours later(or sooner, if the location is irritated) . Podophyllin resin and podofilox lotion remove genital warts by stopping cell growth and may require several applications to work effectively. Podophyllin has to be applied by a medical professional as it must be applied carefully to avoid damaging the healthy tissue around the wart.
Podopfilox lotion/gel – is applied to the wart(s) by the patient at home. The usual schedule is twice a day for 3 days, followed by 4 days without any lotion. This cycle is repeated for 4 weeks. It has few side effects and is well suited for procedure at home.
Cryocautery(also called cryotherapy) – uses liquid nitrogen to freeze more persistent warts every 1 to 3 weeks for a short period. It may cause some discomfort and is not recommended for young children.
Laser remedies – this approach, which uses an intense beam of light, can be expensive and is usually reserved for very extensive and tough- to- treat warts.
Electrocautery – an electrical current is used to super- heat a needle that burns the wart cells and cauterizes the blood vessels. A local anesthetic is used to prevent any pain and the procedure is usually accomplished at a doctor's surgery. Electrocautery is used only after other treatments have failed.
Surgical excision – the doctor will perform minor surgery to remove the wart under local anesthetic.
The physician or nurse should give the patient advice about having sex while receiving treatment.
There are some non- prescription treatments available for genital HPV, but it is advisable to always seek medical advice. Never try to treat genital warts by yourself.
It is necessary that a woman, who is pregnant, or trying to become pregnant, informs her doctor. Podophyllin treatment could harm the developing baby and an alternative treatment should be used.
In June 2006 the first vaccine to prevent four key subtypes of cervical genital HPV was licensed for use in the United States of America.
The vaccine is called Gardasil and it protects women against HPV subtypes 6 and 11, which cause 90% of genital warts, and 16 and 18, which jointly cause 70% of cervical cancers in American women.
The vaccine is claimed to be between 95- 100% effective. It is approved for use in the US for girls and women aged 9- 26 years old. The vaccine may be less effective in women who are already sexually active, as they may have already been infected with HPV.
If you have genital warts, following these suggestions will make an outbreak easier to deal with, and will help protect your mate.
Use condoms when having sex. But remember that condoms will only prevent the transmission of genital warts if they cover the affected areas. Talk to your doctor or nurse for more advice on safer sex.
Take care that your partner has a check- up too, as they may have warts that they haven't noticed.
Keep your genitals clean and dry. Don't use scented soaps and bath oils or vaginal deodorants, as these may irritate the warts.
It is necessary to return regularly for treatment until all of the genital warts have gone so that the doctor or nurse can check progress and make any necessary changes in your treatment. Sometimes therapy can take ages.
Most of people whose genital warts initially disappear will get a recurrence.
In the majority of cases, the immune system keeps the virus under control and eventually destroys it a few years after the first infection.
A few types of the human papilloma virus(notably types 16 and 18) have been linked to changes in cervical cells that can lead to cancer. This is why it is important that all sexually active women have a regular cervical Pap smear test.
A smear test is done by opening the vagina using a speculum(a metal instrument that gently stretches the entrance and the walls of the vagina) and taking a small sample of cells from the cervix with a special swab.
Those cells will be looked at under a microscope. If any changes to the cells are noted, the woman may be asked to repeat the test or will be referred for treatment that may prevent the cells from growing into cervical cancer.
It is necessary to note that cell changes(also called cervical dysplasia) do not indicate that a woman already has cancer. They simply suggest that she is more likely to develop cancer in the future if she does not receive treatment.
A girl who has received an abnormal Pap smear result may sometimes be given a colposcopy to look at cells on the cervix. A colposcope is a kind of small microscope with a light, which is used to view the cervix. The scope magnifies the cervix so the doctor can see any changes or problems. The doctor may take a small sample of cells(called a biopsy) , which will be looked at in a laboratory.
The colposcopy may feel slightly awkward. If the patient has a biopsy taken then they may have a dull ache like a mild period cramp, with slight bleeding.
Medication to remove abnormal cells on the cervix will usually consist of Cryocautery(freezing the cells using a special cold probe) , electrocautery(heating the cells with electricity) or using laser treatment to 'zap' the cells. None of these procedures should be painful, but they may lead to dull aching(like period pains) and watery vaginal discharge that may last several weeks.
A lady who has had visible genital warts in the past is not necessarily at any greater risk of cervical cancer, as genital warts tend to be linked to non- cancer causing subtypes of HPV.
The subtypes of HPV than can lead to cervical tumor may also pose a risk for men and women who have regular anal sex. Though few countries offer regular screening for anal and rectal cancer, several doctors recommend that people who have frequent anal sex(such as gay or bisexual men) should still receive a regular Pap smear test of the rectum and anus. As with cervical cell changes, early detection and therapy can help to prevent cancer from growing.
