Warning signs of skin cancer

Skin cancer can be a deadly battle to fight. With most symptoms left undiagnosed, it can become quite a threat to one’s health. The following guide will help you detect those early signs and seek treatment before it gets too late.

1. Actinic Keratosis
Also known as Solar Keratosis, this condition implies natural and scaly patches of skin found most commonly on the head, around the neck or hands, and these are a result of overexposure to the sun. Although these can deemed as the early signs of skin cancer, the chances of these patches becoming cancerous, is entirely subjective. However, most dermatologists recommend patients should attend to these patches to facilitate early treatment.

2. Farmer’s Lip

Clinically termed as Actinic Cheilitis, Farmer’s Lip condition is similar to Solar Keratosis in its manifestation. This is fairly common in older men and light skinned people. Characterised by swelling of lips, disappearance of the lip-skin border, general scaly texture and patches of unexplained redness, this type of affliction may become a malignant carcinoma if left untreated.

3. Cutaneous Horns

The appearance of funnel shaped growths with a red base is usually the most telling symptom of its appearance. The scaly texture is characterised by the presence of keratin, which is the same protein that constitutes nails. They start out with only a few millimeters in length and diameter, but can grow up to considerable amounts. The bases of these horns contain the carcinogenous cells that, later on, give way to skin cancer.

4. Atypical Moles

Clinically known as Dysplastic Nevi, these are larger, irregular shaped moles, occurring all over the body, with a fading border of mixed colour, which tend to grow with time. Although the appearance of these notch-like moles might not signify cancer straight away, if left untreated, it might soon become cancerous.

The Present Problems in Education






CHAPTER XIV

Conclusion - The Present Problems in Education


The first necessity of the present for teachers and for all concerned with the upbringing of children is to realise the true meaning of education—that it is the process by which we lead the child to acquire and organise experiences that will render future action more efficient; that by our educational agencies we seek to establish systems of knowledge that shall hereafter function in the efficient performance of services of social value; and that the only method which really educates and can educate is the method which evokes the constructive activity of reason in the establishment of the various systems of means. Education does not aim at culture nor at knowledge for its own sake, but at fitting the individual for social service. Our school system tends ever to forget this truth. It is in constant danger of losing sight of this ultimate aim of education by keeping its attention too narrowly fixed on some nearer and proximate aim. It tends often to lay too much stress on mere examinations and examination results. It forgets that the only true test of knowledge gained lies in the pupil's ability to use it intelligently in the furtherance of some purpose—and of some social purpose, and that the ultimate test of a system of education is the kind of social individual it turns out. If our educational system turns out boys and girls who in after-life become efficient workers, efficient citizens, and men and women who have learned how to use their leisure rightly, then it has fulfilled its function. If, on the other hand, it fails in a large number of cases to attain these three ends or any one of them, however it may satisfy the other tests applied, it has not performed its function, is not a system which is "organic" to the welfare of the State.
The second necessity is to realise the true place of the school as the formal agent in the education of the child. Mankind by a long and laborious process has discovered and established many systems of knowledge. He has created language and invented arts for the realisation of the many purposes of life. It is the business of the school to impart this knowledge to the child—to put him in possession at least of some part of this heritage which has come down to him, and to do so in such a manner that while acquiring the experience he shall also be trained in the method of finding and establishing systems of means for himself and by himself. If, however, we lay the emphasis on the mere imparting of the garnered experiences of the ages, the danger to be feared is lest our teaching degenerate into mere dogmatism or mere cram. If, on the other hand, we lay too much emphasis on the ability to self-find and self-establish systems, we are in danger of losing sight of the social purpose of all knowledge—of forgetting that the only justification for establishing a system of knowledge is that it may efficiently function in the attainment of some purpose of life.
Of the more important of the practical problems of our own day and generation the first and most important is to realise that our educational system as it exists at present is not fitted to produce and maintain an efficient and sufficient supply of all the social services which the modern State requires of its adult members, and that we must consider this question of education as a whole and in all its parts, and quite clear of mere party interests. Above all, we must get over the fatal habit of reforming one part of the system and leaving the other parts alone. The whole problem of education from the Primary School to the University requires consideration and organisation. We reform now our Universities, then after a period our Secondary School system, and so we proceed, advancing here, retrograding there, but of education as an organically connected whole we have no thought.
But apart from the want of organisation as a whole our educational system in its parts is at present defective. We require to reconsider the question of how best to educate the children of the very poor. At present we fail in a large number of cases to train up the children of this class to be socially efficient. Economically and morally we fail to reach any high standard. No doubt the home and social environment is all against the school influence; but by a more rational system of early education, by taking more care of the physical development of the child, and, if need be, for a time, making public provision for the feeding of the children of the very poor, we might do much to remove this defect. Above all, we must endeavour to stem the yearly flow of boys and girls at the conclusion of the Primary School period into mere casual and unskilled employments, and must endeavour by some means or other to continue the education of the child for some years further.
Again, we require to make better provision for the technical training of our workmen. By a system of Evening Continuation Schools having as their aim the instruction of the youth in the arts underlying or subsidiary to his particular calling, we might do much to amend this defect. Moreover, the Evening Continuation Schools might play a much more important part than they now do in the securing of the future moral and civic efficiency of the individual and of the nation.
Lastly, and this need is clearly felt by all acquainted with the subject, we require the development and extension of our Technical Colleges, in order that we may adequately train those whose duty in after-life will be the application of advanced scientific knowledge in the furtherance of the arts and industries of life.

10 Things You Need to Know About Immunizations

  1. Why your child should be immunized Children need immunizations (shots) to protect them from dangerous childhood diseases. These diseases can have serious complications and even kill children. More...
  2. Diseases that childhood vaccines prevent Note: Also available are audio, text-only, and other language versions of the Vaccine Information Sheets.
  3. Number of doses your child needs The following vaccinations are recommended by age two and can be given over five visits to a doctor or clinic:
    • 4 doses of diphtheria, tetanus & pertussis vaccine (DTaP)
    • 3-4 doses of Hib vaccine (depending on the brand used)
    • 4 doses of pneumococcal vaccine
    • 3 doses of polio vaccine
    • 2 doses of hepatitis A vaccine
    • 3 doses of hepatitis B vaccine
    • 1 dose of measles, mumps & rubella vaccine (MMR)
    • 3 doses of rotavirus vaccine
    • 1 dose of varicella vaccine
    • 2-3 doses of influenza vaccine (6 months and older) (number of doses depends on child's birthday)
    Recommended doses can also be viewed in chart form. And, concerns about multiple vaccines given in one visit are addressed.
  4. Like any medicine, there may be minor side effects Side effects can occur with any medicine, including vaccines.  Depending on the vaccine, these can include: slight fever, rash, or soreness at the site of injection. Slight discomfort is normal and should not be a cause for alarm. Your health care provider can give you additional information. More...
  5. It's extremely rare, but vaccines can cause serious reactions -- weigh the risks! Serious reactions to vaccines are extremely rare. The risks of serious disease from not vaccinating are far greater than the risks of serious reaction to a vaccination. More...
  6. What to do if your child has a serious reaction. If you think your child is experiencing a persistent or severe reaction, call your doctor or get the child to a doctor right away. Write down what happened and the date and time it happened. Ask your doctor, nurse or health department to file a Vaccine Adverse Event Report form or go to www.vaers.hhs.gov to file this form yourself electronically. More...
  7. Why you should not wait to vaccinate Children under 5 are especially susceptible to disease because their immune systems have not built up the necessary defenses to fight infection. By immunizing on time (by age 2), you can protect your child from disease and also protect others at school or daycare. More...
  8. Be sure to track your shots via a health record A vaccination health record helps you and your healthcare provider keep your child's vaccinations on schedule. If you move or change providers, having an accurate record might prevent your child from repeating vaccinations he or she has already had.  A shot record should be started when your child receives his/her first vaccination and updated with each vaccination visit. More...
  9. Some are eligible for free vaccinations A federal program called Vaccines for Children provides free vaccines to eligible children, including those without health insurance coverage, all those who are enrolled in Medicaid, American Indians and Alaskan Natives and those whose health insurance dues does not cover vaccines and go to Federally Qualified Health Clinics or Rural Health Centers.
