Signs and symptoms of spleen qi vacuity include fatigue hypertension 38 weeks pregnant olmesartan 40 mg order line, lack of strength blood pressure high symptoms generic olmesartan 40 mg fast delivery, somnolence heart attack jack smack u blue purchase olmesartan 10 mg, lack of warmth in the hands and feet, torpid intake, loose stools, a fat tongue with teeth-marks on its edges, and a fine, forceless pulse. Things which can damage the kidneys include excessive fear and fright, excessive use of steroids, excessive use of anti-asthmatics, inap- propriate use of antidepressants, premature sex, and artificial sweeteners. Signs and symptoms of kidney vacuity include fre- quent urination, nocturia, enuresis, low back and knees soreness the Chinese Medical Causes & Mechanisms of Enuresis 41 and limpness, the five softs, and the five slows, i. If there is kidney yang vacuity, then there will also be a pale tongue, a deep, slow pulse, and fear of cold. If there is kidney yin vacuity, there will also be a red facial complex- ion, hot hands and feet, and night sweats. There are several types of repletions of evil qi which may also be involved in enuresis. According to Chinese medicine, the liver is inherently replete in infants and chil- dren. When the liver becomes depressed, it commonly counter- flows to attack the spleen and stomach, especially if the spleen is vacuous and weak and unable to protect itself. What this means in clinical practice is that spleen vacuity is commonly complicated by liver depression. If the liver becomes depressed and the qi becomes stagnant, qi stagna- tion may transform into depressive heat. If this depressive heat joins with dampness, it may give rise to damp heat. However, because of the close association between the liver and the stom- ach, liver depression transforming heat may also give rise to depressive heat in the stomach. One of the functions of the stomach is to send the turbid part of water and foods downward to the kidneys and bladder for excretion. If a hot stomach sends too many water fluids downward, this can cause or contribute to flooding-over of the bladder. And finally, because the spleen is the root of the engenderment and transformation of the defensive qi which is sent up to the lungs for distribution through the exterior, it is said that children easily contract external wind evils. Since the lungs govern the defensive exterior, these wind evils inhibit the diffu- sion and depuration of the lung qi which then inhibits the descen- sion and depuration of water fluids. Some mention also needs to be made of the heart and its role in enuresis. The heart spirit is nothing other than an accumulation of the heart qi nourished and enriched by blood and kidney essence. Further, this heart qi mainly comes from the clear qi upborne by the spleen. Therefore, because of inherent spleen vacuity in chil- dren, there tends to be an inherent heart qi and blood vacuity which is compounded by the inherent kidney vacuity we talked 42 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine about above. When the spirit is quiet and tranquil, heart fire or yang moves downward to the kid- neys to transform cold water. But, when the spirit is disquieted, it tends to stir frenetically and counterflow upward. Hence, heart fire and kidney water fail to interact, and this may also lead to the kidney qi failing to secure and astringe and control urination. In this case, kidney vacuity is the proximate cause of enuresis, but a disquieted heart spirit is a complicating or even causative factor. Before moving on to the Chinese medical treatment of enuresis, I would also like to explain why deep sleep is such a common part of pediatric enuresis. We wake when the clear yang qi is upborne to the heart which allows the spirit to flow freely to and through the sensory orifices to connect with the outside world. We go to sleep when this clear yang qi retreats and descends to the inner and lower parts of the body away from the heart. The clear yang qi is a by-product of water and foods transformed by the spleen and catalyzed by the kidneys, and we have seen that the spleen and kidneys are inherently vacuous and weak in chil- dren. In addition, when the yang qi arises to the heart, it must penetrate any phlegm, dampness, and turbidity before it can flow freely to and through the orifices, and infants and children typical- ly have more phlegm, dampness, and turbidity than adults do. Thus the abnormal deep sleep of the pediatric enuresis patient is typically some combination of spleen-kidney vacuity complicated by phlegm, dampness, and turbidity. Therefore, pattern discrimination is the absolute prerequisite for treating enuresis with TCM. In gener- al, the patterns of enuresis can be divided into vacuity and reple- tion patterns, with vacuity patterns being the far more important in pediatric bed-wetting.

Imported products must be used with some caution heart attack 90 year old buy generic olmesartan pills, as some of them are problematic arteria haemorrhoidalis media purchase olmesartan on line amex, yet get past the investigators arteria rectalis superior buy genuine olmesartan on-line. There are a few patent remedies that are labeled with only herb ingredients, but also contain several West- ern drugs. Some patents from China contain only Western drugs (and say so on the box, in Chinese), but purchasers may be unaware of this because they are told only that this is an effective remedy that came from China. Thus, imported Chinese herb products should be taken solely on the basis of a prescription from a trained health professional. Negative interactions with Western drugs have not been noted for any of the common herb materials when used in the normal dosage range. A few people ex- perience allergic reaction to individual herbs, a problem that often cannot be pre- dicted in advance because these are idiosyncratic responses. A more common reaction is a gastrointestinal response, which might include constipation or diar- rhea, nausea or bloating. Such reactions may occur if the individual has poor diges- tive functions, or if the herbal formula is not quite right for the needs of the individual. In a few cases, use of Chinese herb formulas may cause dizziness, headache, agitation, sleepiness, hunger, decreased appetite, sensation of heat or cold, or other sensory reactions. If such responses persist after about three days of using the herbs, it may be necessary to change formulas. Most American practitioners find themselves too busy (because of the small number of practitioners in this country) to prepare detailed reports of their suc- cessful cases; thus, it is necessary to rely primarily on the large-scale clinical trials conducted in China to learn about the success rates. Such clinical reports, pub- lished in the Chinese language, are abstracted and published in English by the Chinese University of Hong Kong. Massage Chinese massage, or Tui Na as it is called, is a healing modality older than even acupuncture and herbs. It all began when prehistoric man discovered an ache on his body, began to (instinctively) rub it, and found that it felt better as a result. This ancient Chinese bodywork is now gaining rapid acceptance in the Western world. Tui Na (pronounced twee-nah) massage is a complete healing system, like acu- puncture and Chinese herbal medicine. It is probably the oldest system of body- work still practiced, yet its popularity continues to grow. Massage as a part of Chinese medical treatment goes back about 4,000 years. Written massage textbooks began to appear as early as the 4th century B. Massage appears to have developed along- side both therapeutic exercise (Qigong) and acupuncture, as it depends on the same understanding of the meridians and the flow of Qi in the human body. The type of massage known as Qi healing, or curing with external Qi (Medical Qigong Therapy), was developed by Master teachers of Qigong. Benefits Chinese massage is not intended to be an experience of pampering or relax- ation. It is a form of deep tissue therapy that conveys the following benefits: Speeding the healing of injuries and clearing bruises. Some forms of Chinese massage do not require extensive training and can be used at home—two more benefits. Chinese massage therapists use a range of techniques to accomplish this: They press, knuckle-roll, squeeze, knead, dig, drag, pluck, tweak, hammer, push, stretch, vibrate, knock, and even tread on the body with their feet. Massage accomplishes its purpose in three ways: it jump-starts the activity of Qi and blood; it regulates their movement and disperses stagnation; and it removes external causes of block- age (cold and dampness). In Tui Na massage, the patient is allowed or even encouraged to talk while the therapist is working. Tui Na massage takes its name from two Chinese words that mean lift and press. The practitioner pushes hard with the ball of the thumb, then rubs lightly around the area being treated. Tui Na is used to treat a wide variety of conditions that would require a team of physiotherapists, chiropractors, and physicians specializing in sports medicine to treat in the West. One Chinese medical book lists more than 140 conditions that can be treated with Tui Na, in- cluding disorders of the internal organs as well as sprains, pulled muscles, arthritis, and sciatica (a pain in the lower back and back of the thighs).

However, sample size deter- mination is there to ethically justify the study MULTIPLE COMPARISONS in advance – it has no consequences when the results are obtained. A respiratory trial usually contains a number In the respiratory area many test hypotheses of effect variables, and often also a number are stated in terms of mean values, and for of different treatments. Thus there are multiple such variables the sample size is (essentially) comparisons to be done. This poses a major proportional to the ratio (σ/ )2,whereσ is the problem, because of the risk of over-emphasising residual standard deviation and is the mean fluke significances because of many comparisons. When using a To handle the many effect variables we there- multiplicative model for a variable, these entities fore have to predefine which one is to be con- refer to the logarithm of the variable in question. It is from the result on Note that σ means different things in a crossover this variable that the overall statistical conclusion trial and in a parallel group trial – in the former from the study can be drawn. In general one study case it refers to a within-patient variability (more √ can have a few different objectives that are not exactly 2× the residual standard deviation of closely related (like efficacy and safety), and then the ANOVA) and in the latter to a between- a primary variable for each objective should be patient variability. However, it is probably a too sta- residual standard deviation from the proposed tistical approach to focus only on the primary analysis of variance, which might contain a variable when trying to understand the results of baseline adjustment. No variable fetches all aspects of the following table shows some typical values a respiratory disease, and the approach should be of the sample size parameters that can be used for to select the most sensitive variable as primary asthma trials. Each example will be discussed in variable, to decide on the overall conclusion, but more detail below. When it comes to the problem of multiple PEF morning PG 40–45 10–20 4–20 treatment comparisons, the study logic should be (L/min) Symptom score PG 0. With precisely formulated questions the 20 multiplicity problem here should at least diminish substantially. This approach will be illustrated in Here the range is not a range – the lower number what follows. Similarly, for inevitably presents itself, as in so many areas of the range is more of a typical range for which medical statistics. It is however no more sensible to dimensionalise, not a range on what can be to do such analysis on data on lung function obtained. For the crossover measurements of the table, In airways diseases, asthma in particular, the we just note that the AUC refers to AUC-based disease severity varies among patients. Thus average over the full period and that for that the magnitude of the response attainable will variable the pre-dose FEV1 value is used as vary between patients. For PEF morning a baseline numerical effects than patients with large lung is obtained as the mean value over a number volumes, like tall men. This does not mean of measurements, typically 1–2 weeks, and then that the actual benefit to the patient is less, the effect variable as the mean of 1–3 months only that the outcome variable suffers from of data. Similarly, for by measuring lung function in percent of pre- FEV1 the table refers to a measurement both at baseline and end of treatment, but the treatment dicted normal, which tries to capture size dif- value could well be a mean of a number of ferences, instead. Moreover, the FEV data refers to remedy to a larger problem – that there is a 1 the situation when visits to the clinic are spread large heterogeneity in response sizes for some out over the morning, the European style, as outcome variables, which does not necessarily discussed earlier. Changes is not a problem for the proper conclusions of in symptom scores are often small in studies in a clinical trial. Consider a randomised parallel asthmatics with mild–moderate severity, since group study in which treatments A and B they do not have many symptoms on entry. If properly conducted observed rhinitis studies a combination of symptom scores treatment differences should be explained by is often done. If we use the TNS discussed earlier different treatment effects alone, and any claim we typically have a standard deviation of about from the study should relate to the relative 1. Typically, therefore, rhinitis studies can be that the effects differ, say, between men and smaller than asthma studies.
