No cases of enuresis returned or increased after stopping treatment generic propecia 5 mg overnight delivery hair loss vitamins for women, and there were no side effects noted by any patients during the treatment generic propecia 1 mg on-line hair loss cure xx. The shorter the disease duration, the more pro- nounced the treatment outcome. Discussion: This doctor combines two traditional formulas together with modi- fications which results in their self-devised formula for the treat- ment of enuresis. The two main formulas (Si Jun Zi Tang and Wu Zi Yang Zong Tang) address the vacuity of the two main organs involved in enuresis—the spleen and the kidneys. From The Treatment of 30 Cases of Long-term Pediatric Enuresis with Gui Zhi Tang (Cinnamon Twig Decoction) by Wang Wei & Wang Yue, Ji Lin Zhong Yi Yao (Jilin Chinese Medicine & Medicinals), 1998, #4, p. The disease condition manifested as fre- quent enuresis during the night with long, clear urination. There was also sweating after slight exertion, a somber white facial complexion, cool limbs, and fear of cold. Treatment method: Jia Wei Gui Zhi Tang (Added Flavors Cinnamon Twig Decoction) was composed of: Gui Zhi (Ramulus Cinnamomi), 10g Bai Shao (Radix Paeoniae Albae), 10g Sheng Jiang (uncooked Rhizoma Zingiberis), 3 slices Da Zao (Fructus Jujubae), 5 pieces mix-fried Gan Cao (Radix Glycyrrhizae), 6g Yi Zhi Ren (Fructus Alpiniae Oxyphyllae), 15g Tu Si Zi (Semen Cuscutae), 15g Wu Yao (Radix Linderae), 10g Mu Gua (Fructus Chaenomelis), 2 pieces Twenty packets of these medicinals equaled one course of treat- ment. These medicinals were taken after supper, and the parents were instructed not to give the child any soup, water, or other flu- ids prior to the decoction. Also, every evening, the child was awakened in a timely manner to urinate. Study outcomes: There was full recovery in four cases, obvious improvement in 15 cases, and some improvement in 11 cases. Chinese Research on the Treatment of Pediatric Enuresis 55 Discussion: In ancient Chinese medicine, Gui Zhi Tang was a commonly used classical formula for the treatment of tai yang wind stroke (exteri- or vacuity) pattern. However, in modern Chinese medicine, this formula may be used as a basic formula for both external contrac- tions and internal damage. The authors of this article say that, if one analyzes the disease mechanism of pediatric enuresis, one will see that there is lung vacuity and qi weakness as well as vacuity cold of the lower origin. Gui Zhi Tang not only regulates and harmonizes the constructive and defensive, it also warms and frees the flow of the bladder channel. Yi Zhi Ren and Tu Si Zi are added to warm the kidneys and secure and contain. From The Treatment of 43 Cases of Pediatric Enuresis Combining Jin Suo Gu Jing Wan (Golden Lock Essence- securing Pills) with Liu Wei Di Huang Wan (Six Flavors Rehmannia Pills) by Zou Shi-chang, Ji Lin Zhong Yi Yao (Jilin Chinese Medicine & Medicinals), 1998, #5, p. Twenty-five cases were between the ages of 5-10, and 18 cases were between the ages of 10-16 years old. These children had enuresis as much as 2-3 times per night and as little as 3-4 times per week. Among the patients, 18 cases had frequent urination during the day, and 14 cases had urgency of urination, fatigued spirit, and lack of strength. Their tongues were pale with thin, white fur, and their pulses were fine and weak. Treatment method: Five to 10 year-olds took five grams of Jin Suo Gu Jing Wan (Golden Lock Essence-securing Pill) two times per day; 10-16 year-olds took eight grams two times per day. At the same time, 5-10 year-olds took three grams of Liu Wei Di Huang Wan (Six Flavors Rehmannia Pills) two times per day; 10-16 year-olds took 56 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine five grams of Liu Wei Di Huang Wan two times per day. Study outcomes: In general, after approximately seven days of treatment, the child was able to wake to urinate and the frequency of enuresis was reduced. Most times, it took 20-30 days of taking medicinals to stop the enuresis. Among the 43 patients, the longest a patient took the medicinals was 30 days and the shortest length of time was 10 days. Therefore, the author believes the appropriate treatment to stop enuresis is to strengthen, regulate, and supplement the kidneys and secure and contain. Jin Suo Gu Jing Wan secures the kidneys and astringes the essence and, therefore, can be used to treat enuresis due to kidney vacuity. Jin Suo Gu Jing Wan and Liu Wei Di Huang Wan are available in ready-made form from many different companies in North America and Europe.

Tus propecia 5 mg low price hair loss cure earache, they remained the normal female ovaries propecia 1mg without prescription hair loss on back of head, fallo- pian tube, and uterus we saw in the abdomen. All of this embryology and endocrinology had just been worked out in detail in animals and was only now being applied to cases in humans. Tere was a beauty to the embryological story that had been discovered, so sequential and understandable. And like all hu- man systems, it could go awry—as it had in this patient. Actually, the child would have been a perfectly nor- mal female except for the presence of excessive androgens from a defect in the adrenal gland. Te androgens after birth caused him to grow rapidly and to develop male secondary sexual characteris- tics at an early age (the growth of the penis and facial hair his wife told me about). Te cessation of growth came from the great ac- celeration of bone development that comes from male hormones (androgens) and the closure of the bone-growth centers when the bone age reaches about sixteen years. Te surgeon asked me why the patient did not menstruate or develop breasts at the age of puberty. In addition, the androgens opposed the action of estrogen at the tissue level, thus preventing the patient from menstruating through his penis. Male hormones will usually override female hor- mones and dominate the biologic scene, both during fetal develop- ment and later in life. In mild forms of this condition, menstruation has occurred in some cases, to the great consternation of everyone. Usually they think it is bleeding from the kidneys, and everyone is shocked to find a uterus in an otherwise normal boy. I told the surgeon and the gynecologist that I ruled out a rare masculinizing/androgen-secreting tumor because the process be- gan before birth; a tumor that secretes androgens is never congen- ital. It was clear that the removal of all internal genitalia, including the ovaries, was justified. It was clear to me that the patient was a fully functioning man, married, and responsible for Te Woman Who Believed She Was a Man 47 two adopted children. I could think of no good and plenty of harm from laying out all the facts. It seemed to me that our responsibility was to do everything we could to assist him in remaining the best possible man he could be. Tis meant removing all tissue which served no male purpose and which could be a source of cancer in later life. We agreed to call the operation an excision of aberrant go- nadal and genital tissue. After the operation, we collected some urine and confirmed the very high levels of adrenal androgens and the diagnosis of con- genital adrenal hyperplasia. I really did not need to see him at all after the operation, but I think my curi- osity was just too much for me. He was short, about five feet three inches, heavily bearded, and very muscular. He later ran for public office, and I saw his picture in the papers and on television a number of times. Here in one sense was indeed a woman (fe- male by chromosomes, gonads, and internal genitalia) who thought she was a man, so much so that it was impossible for all who knew him to tell the difference between him and any other man. Add a hydrogen atom to the basic mole- cule and you get testosterone and males. If he believes he has a disease, he will behave as if he has that disease. And as in this patient, if a person thinks he is a man, he will act as if he is a man. How else can we explain some people with severe disease who function so well, while others with little disease do so poorly? I became determined to learn how to change perceptions from unhealthy ones to healthy ones.
