Everyone knows that it is easier to wake up in the morning when the next day holds promise and excitement discount 15 gr differin visa. Star charts use this concept to their advantage by offering a child a star on the cal- endar for each dry night. When the child collects or obtains a cer- tain number of stars (usually 3-7), they are given a small reward. When the child is dry for a longer duration, such as 21 nights, he or she receives a larger, more appreciated and anticipated prize. The explanation for the effectiveness of this treatment is that, by rewarding the child, you put the reticular activating system of the brain in a more heightened state of readiness and it is better able to wake up when the bladder signals that it is full. For some, this method alone is sufficient to make them responsive to a full blad- der. However, according to some authorities, if this treatment does not improve the enuresis within two weeks, its use should not be continued without being combined with another therapy. Dr Richard Butler, a psychologist, suggests using a point system The Western Medical Treatment of Enuresis 33 instead of the star charts. This does not have to be an expensive gift or reward but instead may be time set aside for a particular activity that the child enjoys doing with their parent. For example, the child may have to earn 30 points to enjoy an afternoon at the zoo, playing baseball, or having a camp-out. You agree that a certain amount of points will be rewarded to them for positive behavior outcomes that have previously been identified and agreed upon and then help the child achieve these over a period of time. Children will soon become competitive if supported by the adults that are around them and will strive to attain this goal. Butler argues that this method is preferable to the star system of only rewarding the child when they do not wet the bed. He feels the child will be totally demoralized and stop trying if he or she accu- mulates too many consecutive nights of wetting the bed. Pharmacological therapy This section is an introduction to the pharmacological treatments currently available in modern Western medicine to treat enuresis. The intent of this section is to educate the practitioner on possible treatments their patients may have received prior to coming to your office and to supply the practitioner with information to bet- ter educate their patients and their families on an effective treat- ment plan.
