article: In addition to reducing the overall load carried, you can also decrease the likelihood of soreness or injury by making sure that your child wears the backpack properly. The weight of the pack should be distributed primarily over the shoulders and upper back, with the chest in support these are some of your strongest muscle groups. Straps should be snug without cutting into the shoulders. The bag portion should be centered on the mid-back, with the bottom of the bag sagging no more than four inches below the waistline. The bag should never touch the child's backside while being worn. Ask your child to think of the backpack as a temporary conveyance like a delivery truck and not as a permanent home for her stuff like a motorhome. She should use it to carry what she needs when she needs it to where she needs it. Load and reload it frequently with what she needs right then. Kids should use a locker and/or desk as their primary storage spaces, not their backpacks. Recommend that she make more frequent trips to lockers or desks in order to unload and reload the backpack with what she needs at that moment. Procrastination can also cause overload problems, by causing a kid have to bring all her books home on Friday, for instance. Work with her to make sure homework and assignments don't back up to the point where everything needs to be done all at once. It may be a long shot depending upon your school's budget situation, but you may want to ask whether your child can have two copies of her textbooks one for school and one for home. The adoption of e-textbooks (at least as a supplement for homework) may be a more practical and cost-effective solution. Make sure you educate your child about avoiding carrying a bag on one shoulder. Some kids may want to switch from a backpack that rests on both shoulders to one shoulder, such as a messenger bag. This can put stress on that shoulder, in addition to the child hiking his shoulder up to keep the backpack in place. This can lead to shoulder and neck pain if it is done on a regular basis. Both shoulder straps must be used to effectively balance the load even if slinging the pack over only one shoulder is considered "cooler." Most of the prevention measures for backpack safety involve strains and injuries caused by overweight loads. However, when it comes to injuries that lead to emergency room visits, less than one-fourth involve the shoulders (12%) or back (11%), and the most common cause of significant backpack injuries is tripping over one (28%). The majority of all ER-worthy backpack injuries involve the head or face, hands, wrists, or elbows, all likely spots for trip-and-fall injuries. What does all this mean? While it is important to take precautions against your child lugging around a backpack that is too heavy, make sure she is just as vigilant about paying attention to her surroundings to avoid injuries caused by tripping over a backpack or being struck by a swinging bag, strap, buckle, etc.

article: The skin surface is made out of keratin, a thin layer of cells which protects the skin. The keratin layer is continuously shed and replaced with a new batch of cells. Instead of a normal exfoliation, the cells can move deeper into the skin and continue to proliferate. Keratin will be secreted towards the inside of your body, creating a cyst. This is, in itself, not harmful or dangerous -- it's simply not aesthetically pleasing. It's only if a tumor or infection develops that this abnormal proliferation is something to worry about. Sounds pretty harmless, huh? Even just a hair follicle can create a sebaceous cyst. If you were worried you were suffering from some serious health problem, know that it can really just be because of a hair. When this is the cause, a small pocket of modified skin found in the dermis, which is the second layer of the skin, is referred to as a hair follicle. Each hair grows from one of these pockets. Follicles damaged by a constant irritating factor or surgical wound will suffer damage and scarring, leading to an ingrown hair. If a cyst is ruptured, bacteria can contaminate it, leading to infection. The cyst will become painful and will start to resemble a pimple. It will ooze pus as well as moist keratin deposits. The area around it will be red and slightly swollen. If this happens, you need to seek medical treatment. If the infection goes untreated, it will get worse and worse and can eventually affect your entire body. While a cyst itself isn't anything to be greatly concerned about, an infected cyst does require action. Even if a cyst is not infected, it can still become inflamed. If the cyst is constantly exposed to an irritating factor, such as rubbing against a rugged fabric, it will become inflamed. Luckily, it's usually fairly easy to reduce the inflammation, either with NSAIDs (like ibuprofen) or just to remove the irritating factor. An inflamed cyst is difficult to remove because the area is vulnerable to infection. If a minor surgical procedure is necessary, it may be postponed until the inflammation goes away. A ruptured cyst will trigger an immune reaction if a foreign material infiltrates your skin. This will cause a collection of pus called an abscess to form. This is more likely to happen in large cysts. A ruptured cyst is better off seen by a doctor. A burst cyst needs to be kept as clean and hygienic as possible. Visit your doctor for advice on how to care for the cyst and what medical treatment you should seek.

article:
During the abdominal palpation, the vet feels the bitch's tummy for the presence of puppies. The earliest date that this is likely to be successful is at least 21 days after mating. At this early stage the vet is feeling for an enlarged, thickened womb rather than puppies (which are like small blobs of jelly at this point). The best time for abdominal palpation is day 28. This is because the puppies are now big enough to make a "bump" in the womb, much like beads strung along a necklace. By day 35, the each puppy is surrounded by his own fluid capsule and the vet feels something akin to a fluid string of sausages. Bear in mind that at 28 days each puppy swelling is a maximum of 25 mm (1 inch) in diameter, making it difficult to differentiate embryos in a womb from food in the gut or feces in the bowel. Furthermore, if your dog is tense and braces her belly wall, it can be impossible to feel anything worthwhilethe equivalent of trying to see through a window that has been painted over. Likewise, a single puppy can easily be missed, or mistaken for another structure such as the bladder, a kidney, or even feces in the bowel. Don't feel too frustrated with the veterinarian when she suggests a pregnancy test, as the abdominal palpitation can be inconclusive. The blood tests looks for high levels of the pregnancy hormone, progesterone. To be reliable, this test should be done after day 28. Before this it's possible to get false positive results, because the high levels might be a result of delayed decay of the hormone present during ovulation. However, after day 28, high levels of progesterone confirm pregnancy. Ultrasound scans are a popular way of confirming pregnancy, because in the hands of a skilled operator small changes in the womb can be detected as early as 18 days. The other advantage is that the technician may be able to give you an idea of how many puppies are in the litter, which is useful to know when it comes to the birth, or whelping. Placental units can be visible from day 18, and from day 28 the fetal heartbeats are visible. Note that the ultrasound is a noninvasive procedure that is done while your dog is conscious. The ultrasound equipment sends a beam of high-frequency sound waves toward your dog's uterus, and the waves created "echoes" which are converted into images. This is considered a safe procedure. The fur on your dog's abdomen needs to be clipped so that the probe can make good contact with the skin. X-rays have largely been replaced by ultrasound for detecting pregnancy in dogs. Because they are only of use once the fetal skeleton is calcified, which happens after day 49, the diagnosis is made relatively late in the pregnancy. As for safety, while the risk of irradiating puppies in the womb is unlikely to do harm, it is likely your dog will need to be sedated, because current health and safety regulations for the operators of x-ray equipment mean they are not allowed to be in the room when the exposure is made. Since many bitches, especially when heavily pregnant, are not comfortable lying still and are likely to get up when left, the only other option is to sedate them. Sedating a pregnant bitch is best avoided because of the risk of a drop in blood pressure to puppies in the womb. For these reasons, the use of radiography for pregnancy diagnosis has gone out of vogue.
