Td vaccination - what is it?

Td is a diphtheria-tetanus toxoid with a reduced amount of diphtheria toxoid in comparison with DT toxoid. It is used for the prevention of diphtheria and tetanus in children older than 6 years and adults. 1 ml Td toxoid containing 10 units of diphtheria and tetanus toxoids, whereas in 1 ml of DPT vaccine contained 30 units of diphtheria toxoid.

When and how do Td vaccination

Vaccination is repeated booster against diphtheria and tetanus for children over 6 years of age who have previously received the first vaccination and revaccination against these infections DTP.

If a child after 6 years have not been vaccinated against diphtheria and tetanus vaccination him Td toxoid 2 vaccinations with an interval of 30-45 days, and then six months later - the first revaccination after 5 years and the second booster. Subsequent booster for adults are held every 10 years.

Td vaccination is also made to replace DTP or Td toxoid children with severe general reactions (40 ° C or higher) or post-vaccination complications to the previous administration of DTP or DT. If the reaction at the time of vaccination developed in the first administration of DTP (ADF), the second administration is performed Td toxoid not earlier than 3 months. If the reaction is developed in the second administration of the vaccine or toxoid within the vaccination, the course of vaccination against diphtheria and tetanus Tetanus - a constant companion of man  Tetanus - a constant companion of man
   is complete. In both cases, the first booster Td toxoid spend 9-12 months. If the reaction is developed on the third injection of the vaccine as part of DPT vaccination, first revaccination Td toxoid spend 12-18 months.

Td vaccines are also in the outbreak of diphtheria. Vaccination Td toxoid can be carried out simultaneously with vaccination against poliomyelitis Polio - why immunization of the population?  Polio - why immunization of the population?
   and other vaccines. Td toxoid administered intramuscularly or subcutaneously at a dose of 0, 5 ml.

Are there any contraindications for Td vaccines?

Permanent contraindications for this vaccination is not, is not recommended to conduct vaccinations to pregnant women only. Children and adults who recover from acute illness, depending on the severity of the disease and undergoing general state of Td vaccination is done 2-4 weeks after recovery. If the disease is mild, without fever, the vaccination can be done immediately after recovery.

If a child or adult suffers from some chronic disease, the Td vaccination is carried out within 2-4 weeks after the beginning of remission. Regular, non-progressive and life-threatening symptoms are not a contraindication for vaccination - it can be done with treatment of the underlying disease.

Td vaccination is not contraindicated in any immunodeficiency and HIV HIV - can be slow, can not be stopped  HIV - can be slow, can not be stopped
 -infektsii and during maintenance treatment of these conditions, including steroid hormones.

Before vaccination doctor must inspect the child or adult, it measures the temperature and makes an entry in the medical card of admission to the vaccination.

In outbreaks of diphtheria Td vaccination is even against the background of acute illness or exacerbation of chronic diseases. If the previous administration of Td toxoid there was a strong reaction of the body, a second dose is administered tetanus toxoid in patients receiving steroid hormones (eg, prednisone), appointed the day before vaccination and immediately after it.

Td vaccination - whether it is the reaction?

Td toxoid is generally well tolerated, and children and adults, general and local reactions to its introduction are extremely rare. Td vaccination is normally tolerated even by children suffering from atopic dermatitis and bronchial asthma.

However, even such a "lightweight" vaccination may be the reaction. Of the local reactions are redness, swelling and dense infiltrate at the injection site. All these events are themselves without treatment in a few days.

The general reaction to vaccination can be a small rise in temperature, malaise in the first two days after inoculation. Very rare allergic reactions, however, can not eliminate them. Allergic reactions often manifest as hives and swelling Prevention and treatment of edema - it is important to understand the root cause  Prevention and treatment of edema - it is important to understand the root cause

Pituitary adenoma in children - a rare disease

September 18, 2013

 pituitary adenoma in children
 Pituitary - is a small gland shaped like peanuts, located in the brain at about the same level as the eyes. Pituitary adenoma in children is rare, but still there are such cases. Typically such adenomas are benign, i.e., non-cancerous tumors. However, because the pituitary gland plays an important role in regulating the body's hormonal levels, even minor changes in its structure can have a serious impact on the mood of the child's ability to concentrate, as well as the overall development. Pituitary adenomas may also cause the symptoms associated with the pressure of the tumor on adjacent parts of the brain, such as headaches and vision problems.

The classification of pituitary adenomas

Pituitary adenomas that produce hormones are collectively called functional adenomas, but they are also called by the name of the hormone secretion which they cause. For example, an adenoma that produces prolactin, called prolactinoma; adenomas secreting corticotropin kortikotropinomy call, and so on. Each of these adenomas in patients causes a characteristic syndrome associated with the secretion of a hormone.

Adenomas that do not produce hormones called nonfunctional. They may cause problems that are a result of pressure on different portions of the tumor in the brain.

Symptoms

Symptoms of pituitary adenoma in children can range from small and poorly defined, such as lethargy or, on the contrary, the restlessness, to more serious symptoms, such as headaches, vomiting and dizziness. One of the problems associated with the diagnosis of pituitary adenoma, is that most of the children from time to time that are sluggish, but very active, and the parents do not always turn on this issue to the doctor. In most cases, they're right - as a rule, such changes are associated with the usual mood swings naturally to everyone. However, if the child's mood changes very often or abruptly, or it can be a long time irritable, contact your doctor.

In older children and adolescents may be other symptoms of pituitary adenomas, including - problems with growth and development. For example, girls and boys under the age of nine years, there may be signs of puberty - in such cases we say about early puberty. This may be a pituitary adenoma that produces luteinizing hormone. In this case, the girls begin to grow breasts, pubic hair appear, menstruation begins. The boys grow genitals and begin to grow pubic hair and face. Pituitary adenomas secreting FSH may, on the contrary, slow sexual maturation and development as a whole in both sexes.

If pituitary adenoma limits gonadotropin secretion, it may affect the development and function of the ovaries and testes. In this case, the teenage boys during puberty does not start on time and sometimes they fall out hair on the face and groin. In teenage girls, too, slowing down puberty; If menstruation has already begun, there may be a violation of the menstrual cycle, as well as the loss of pubic hair.

In children with decreased secretion of adrenocorticotropic hormone (ACTH) can be lowered blood sugar level Blood sugar - one of the main indicators of human health  Blood sugar - one of the main indicators of human health
 ; observed symptoms such as fatigue, low blood pressure, sometimes - dizziness, when the child gets up. On the other hand, pituitary adenoma that produce ACTH may cause delayed growth and puberty, weight gain, acne, deposits a large amount of subcutaneous fat on selected areas of the body such as on the back and base of the neck. Adenomas of this type may also cause weakness, depression, memory problems, and sudden partial or complete loss of vision.

Some pituitary adenoma can disrupt the thyroid gland, secreting too much thyroid-stimulating hormone (TSH). This leads to an increase in the thyroid gland, in the neck and the person has a noticeable bulge, which is called goiter. In children with these tumors develop hyperthyroidism - a violation whose symptoms include nervousness, increased heart rate, weight reduction, strong appetite, increased sensitivity to heat and sweating.

Pituitary adenomas, which lead to a decrease in TSH, can also have a significant impact on the child. As a rule, children have trouble concentrating and learning, there are symptoms such as fatigue, constipation, dry skin, increased sensitivity to low temperatures. In girls, low levels of TSH can lead to menstrual irregularities.

Another type of pituitary adenomas reduces secretion of vasopressin - a hormone which affects the reabsorption of water by the kidneys. The lack of vasopressin causes severe thirst, frequent urination, a very strong appetite, accompanied by exhaustion, weakness, and fainting.

Pituitary adenomas that produce excessive amounts of the hormone prolactin, can lead to the cessation of menstruation in women, and cause impotence Impotence - a female perspective on the problem  Impotence - a female perspective on the problem
   and young people. In young children, such adenomas often slow down or even stop puberty.

   produces excess growth hormone, in the absence of treatment, which may result in gigantism.

If a child has already begun or completed puberty, excess growth hormone can cause an abnormal increase in the feet, hands, lips, nose and jaw - a violation is called acromegaly. These patients are also observed excess sweating and fatigue.

The most common type of pituitary adenoma in children is craniopharyngioma - a tumor that forms from the embryonic cells of the pituitary gland. Such adenomas are innate. Often, they put pressure on the optic nerve, resulting in impaired vision. Craniopharyngioma also lead to a deficiency of the majority of hormones produced by the pituitary gland, resulting in that there may be any violation of the above symptoms.

Diagnostics

Pituitary adenomas can be detected using X-ray, computed tomography or magnetic resonance imaging. However, many pituitary adenomas are so small that they can not be seen with the help of medical imaging; they can be diagnosed using various laboratory tests. For example, doctors may do a blood test or urine test for certain hormones, a few hours after the child entered a substance that normally should stimulate or inhibit the secretion of certain hormones.

It is often used in the diagnosis of glucose tolerance test. In the morning, before breakfast, child drinks containing glucose solution, after which he bled for analysis, and the measured blood sugar and growth hormone.

Treatment

Pituitary adenomas that produce excessive amounts of prolactin, are successfully treated with the help of drug therapy in 89% of children with this disorder. Many other kinds of pituitary adenomas is also good to treat these or other drugs. If the child contraindicated medications commonly used for treatment of pituitary adenoma, or if they were ineffective, can be assigned to minimally invasive surgery, radiotherapy, or a combination of several methods applied. Invasive surgery, requiring craniotomy are needed only in rare cases - for example, when the tumor is very large and continues to grow, and, if an adenoma can lead to vision loss and other serious consequences to health.

In some cases, after treatment, patients can be assigned to hormone replacement therapy.
