Childhood Asthma


Eczema and Asthma Part 2 - Childhood Asthma
Jimi Windmills

Introduction
In part two, we will look at childhood asthma, first exploring some fundamental differences between the physiology of children compared to adults, and the importance of inspection as a diagnostic technique in paediatrics. We will then compare the treatment of asthma in children to the treatment of asthma in adults, with reference to Scott and Barlow’s text on paediatric acupuncture, and other relevant texts and articles.

Physiology of Children
There are many aspects in which the physiology of children differs from that of adults. For a large part, this centres on the development of a well functioning digestive system. The spleen coordinates and drives the entire digestive process, and since, as Scott and Barlow point out, before birth, a baby has received all its nourishment from its mother, it has never had to rely on the proper functioning of its own mechanisms for generating Qi. This results in immense pressure on the spleen, as it tries to take all the food coming into the body for the first time, and convert it into Qi and Blood. This makes children particularly susceptible to disorders involving the spleen (Scott and Barlow 1999: 3-4).

Children are often Yin deficient. This is evidenced by their susceptibility to Hot diseases, fevers and convulsions. Children are Yang in nature, compared to adults, they are always moving, and always changing (Scott and Barlow 1999: 4). Given their propensity for rapid change, children are particularly vulnerable to changes in diet, succumb rapidly to viruses, and are affected quickly by hot or cold weather. When sickness takes hold, progression of the disease is often frighteningly rapid, quickly developing fevers, acute diarrhoea leading to dehydration, or chest infections that transform into pneumonia, threatening the child’s life (Scott and Barlow 1999: 4-5).

While it is certainly true that children get sick easily, and progression of disease can be very fast, it is reassuring that they also respond very quickly to all manner of treatment (Scott and Barlow 1999: 5). This capacity to be influenced easily by external forces holds true for the impact of the seven emotions on children, who having little awareness of their emotional state, are directly involved in the emotional affairs of their parents, and others close around them. Stress, anxiety and frustration in the parents are quickly mirrored by their children. In saying this, it is important to clarify that in general, children do not suffer from Qi stagnation as a result of repressing emotions. Patterns that look like Liver Qi Stagnation or Yang rising, are most often food stagnation and accumulation disorder. The most common sign of liver involvement is stirring of Liver Wind causing febrile convulsions (Scott and Barlow 1999: 5).

The Importance of Inspection
It is difficult to take a child’s pulse, and often they are unable to speak for themselves because they have not learned how, or are too shy. Sometimes an otherwise verbal child might be inhibited in a clinical setting. This makes asking (the parents), and inspection, particularly of the child’s face, the two most important methods for diagnosing children. Inspection is the most important of the four diagnostic methods for several reasons. It does not rely on subjective information provided by an anxious parent, or unwell child, who may or may not fully grasp the meanings of the questions. Inspection is the best way to assess the overall level of Qi of a child, and the vividness of the colours of the face in an immediate clue to the health of the child. It also provides a way to gauge the efficacy of previous treatments, as the child will appear healthier and more Qi-full (Scott and Barlow 1999: 58-60). The face of a child is the most important area for inspection. By looking at the face, particularly focusing on the eyes, and the quality of the Shen, a practitioner is able to assess the child's spirit, and make a prognosis on the recovery. The colour of the face also provides key diagnostic information, and is often more reflective of the health of the child, than either the tongue or the pulse. Other important aspects of inspection are the movement of the child, inspection of the orifices, and the finger vein. The finger vein is located on the radial side of the index finger, and when present can be interpreted diagnostically (Scott and Barlow 1999: 59-61).
Asthma – Treatment in children and Adults
Asthma patterns in children under 5 years of age are very different from those seen in older children and in adults, according to Scott and Barlow. When a child under 5 has asthma two factors will always be present: Phlegm and Lung deficiency. In a majority of cases there will also be an underlying lingering pathogen (1999: 229). Scott and Barlow assert that the most common aetiology of asthma is repeated use of antibiotics to treat acute coughs. Their pattern of asthma in children under 5 is accumulation of Phlegm in the Lungs, with underlying Lung and Spleen Qi deficiency, complicated by a lingering pathogenic factor. They describe the pathogenesis of the disease as beginning with accumulation of food which restricts the flow of Qi, this generates Phlegm which accumulates in the Lungs. The Lungs become deficient and combined with the already deficient Spleen, leads to asthma. This pattern can be complicated by a lingering pathogen, which may be Hot or Cold in nature (Scott and Barlow 1999: 230-1). As the signs and symptoms listed in Scott and Barlow are extensive, they will be supplied in Appendix 1.

Scott and Barlow’s stress that in this pattern with Phlegm, Lung deficiency and a lingering pathogenic factor, that it is important to treat the Lungs and the Phlegm first, and not treat the lingering pathogen until there is a reduction of Phlegm and an increase in Lung Qi.

From Scott and Barlow:
  • The main points are Lu5, Lu7, Lu9, Ren12, Ren22 and St401.
  • For Phlegm with accumulation disorder add Si Feng (M-UE-9)2.
  • Lung and Spleen Qi deficiency (normal and hyperactive) add Sp6 and St36.
  • Lingering pathogenic factor (cold) add Bai Lao (M-HN-30), Bl12, Bl20, Bl18, Bladder points can also have moxa applied, along with moxa at Ren123.
  • Lingering pathogenic factor (hot) add Lv2, Lu10, and apply a dispersing technique to the main points, particularly Lu5 and Lu7 (1999: 233-4).

The aetiology of asthma in adults begins with Wind-Heat or Wind-Cold repeatedly invading the body, and settling in the Lungs where it impedes the flow of Lung Qi, which results in the accumulation of Phlegm. Similar to Scott and Barlow’s pattern for children, Maciocia also identifies improper diet injuring the spleen as being a contributor to the production of Phlegm. Another aetiological factor is weak constitution. A child who suffers a long illness, will develop Lung and Spleen deficiencies, impeding the transformation of fluids and leading to the production of Phlegm. While Scott and Barlow assert that adult patterns of asthma are very different to those of young children, Maciocia's, aetiology and pathogenesis seems quite similar. Asthma, according to Maciocia, can be split into two categories, acute phase, and chronic phase. Acute phase can be further subdivided into Cold Phlegm and Hot Phlegm patterns. Acute phase treatment happens during an attack, or between attacks during a period in which they occur frequently. Maciocia's differentiating features are listed in Appendix 2. The treatment principal for Cold Phlegm is to warm the Lungs, scatter Cold, resolve Phlegm, and relieve breathlessness (Maciocia 1994: 176). The point prescription is Lu7, Bl13, Lu1, Lu6, Ren22, Ren17, St40, Pc6, reducing or even technique, and moxa (Maciocia 1994: 176). The treatment principle and points for Hot Phlegm is to clear Heat, restore the descending of Lung Qi, resolve Phlegm and stop wheezing. Lu5, Lu10, Lu6, Bl13, Lu1, LI11, Pc5, St40, Ren22 (Maciocia 1994: 176).

Recent Research
In a research article published in the Journal of Traditional Chinese Medicine children diagnosed with bronchial asthma were treated using acupuncture and herbs. In the article there is very little mentioned about the pattern diagnosis, this was a common failing among most of the articles I located to do with acupuncture, there were very few dealing specifically with acupuncture to treat asthma exclusively in children. The article, Clinical Research of Acupoint Application for "Treatment of Winterdisease in Summer" Used to Prevent and Treat Bronchial Asthma in Children, was particularly interesting in that it placed a big emphasis on the season in which the treatment took place. This was an element that was not present at all in the works of Scott and Barlow, or Maciocia. In this article, points were chosen (all of which seem reasonable, in the absence of a treatment principle), including Bl13, Bl43, Dingchuan, Ren22, Ren17, Du14, Ren4, Ren8, Bl26, and Pc6, many of these were used in the other protocols previously explored, however points specifically to clear Phlegm, a pathological component in each of the other authors works, are notable in their absence. These points were needled on the hottest days in summer, and on the coldest days of winter. The authors of the study also prescribed herbal treatment.

Conclusion
In this second part of the assignment, we looked at childhood asthma, and some of the most important differences between the physiology of children compared with that of adults. We saw that the most important element of diagnosis in paediatrics is inspection, especially of the face. We then compared the treatment of asthma in children to the treatment of asthma in adults, and saw that they were quite similar. Finally we took a brief look at a research article, which in comparison to our other two texts outlined a unique method of treatment for paediatric asthma using acupuncture.

1 Scott and Barlow caution not to use St40 in cases where the patient is extremely Phlegmy for fear of provoking asthma attack. Use Ren22 and Ren12 for the first few treatments.

2 Like ST40 we are cautioned again against the use of Si Feng in cases of extreme phlegm, since the point can release a lot of heat and Phlegm into the system and make the patient worse. Again use Ren 22 and Ren12 until a lot of the Phlegm has cleared.

3 Do not treat lingering pathogenic factor until Phlegm had been resolved and deficiency almost completely tonified.

ECZEMA


Eczema and Asthma Part 1 - Eczema.
Jimi Windmills

Introduction
It has been a while since I posted so I thought I would post a two part short article I wrote a little while back. In these two brief articles I discuss two conditions that often present simultaneously in patients, Eczema and Asthma (particularly in children).

Aetiology and Pathogenesis
In Chinese Medicine, eczema is traditionally known as seeping sap sores. It is an inflammatory response that occurs superficially on the skin. It typically presents with red skin, papules and vesicles, weeping and crusting. In more chronic cases it can eventually lead to scaling, pigmentation change, and lichenification (Crawford 1988: 18).

There are both internal and external causative factors. External Wind, and internal Heat and Damp. A person generates internal Heat, primarily by regular consumption of hot, pungent food. This causes a disruption to the spleen which leads to the accumulation of Damp, and a deficiency of Wei Qi. Wind invades while the Wei Qi is low, and having penetrated, accumulates at the skin level with the Damp and Heat to cause Eczema (Crawford 1988: 18). In the deficient pattern of eczema, Blood is consumed by a chronic heat in the intestines, causing a deficiency of Blood. This Blood deficiency leads to a rising internal Wind. The Wind and the dryness from the Blood deficiency, fail to nourish the skin, resulting in dry skin and eczema (Crawford 1988: 18).

Yan and Zhu agree that there are two predominant patterns of eczema (Yan and Zhu 2005: 89). Both agree on the acute pattern involving Wind Dampness and Heat, Yan and Zhu call it “Fulminant wind, dampness & heat” (2005: 89), while Crawford in her article titled The Acupuncture Treatment of Skin Diseases calls this pattern “Damp-Heat complicated with EPF Wind” (1998: 18). While their pattern identification is similar, their treatment principles differ, and point prescriptions utterly divergent. First we will examine the excess condition.

Excess Pattern Eczema - Wind, Dampness and Heat.
This pattern is characterised by a red rash with exudate and itching, and the expression of the pattern can change depending on which pathogenic factor predominates (Yan and Zhu 2005: 89). Crawford adds the following differentiating features; erythema, vesicles, erosion, oozing, crust, bitter taste and stickiness in the mouth, scanty deep yellow urine, constipation, a red tongue with sticky yellow coating, and a soft, rolling or rapid pulse (1998: 18-19). Yan and Zhu point out that in excess patterns of eczema, one of the three external influences will often predominate;

  • Wind dominates – Most likely to affect the upper body, or widely spread with minimal exudate.
  • Heat dominates – Affected area will be bright red and may have many pustules.
  • Damp dominates – There will be raised blisters with excess exudate. This may be accompanied by heaviness in the chest and difficult inhalation (Yan and Zhu 2005: 89).

The treatment principle for this pattern, according to Yan and Zhu, is to expel the wind, clear the heat, and resolve the dampness (2005: 89). Crawford tells us to clear Damp-heat and relieve itching (1998: 18). It is interesting to note that while Yan and Zhu have included GB31 in their point prescription, they neglected to include 'stopping the itch' in their treatment principle. Crawford on the other hand overlooks wind clearing, from her principle and core prescription1. Yan and Zhu and Crawford pick quite different points, with only LI11 being a common component of their core prescriptions. To treat this condition Yan and Zhu have the primary point prescription of Du14, LI11 ST36, SP6, and GB31 (Yan and Zhu 2005: 89). To this they add auxiliary points: LI4 for prevalent wind; SP62 and Ren12 for prevalent damp; LV1 prick and bleed for prevalent heat; LV5 and Ren3 for damp affecting the scrotum (Yan and Zhu 2005: 89). Needle using a sedating technique, once a day, with 20-30min needled retention (Yan and Zhu 2005: 89).

Crawford prescribes LI11, SJ5, BL25, and SP9 with a reducing method, and recommends Du14, if there is concomitant fever, and HE7 if there is itch. Crawford also suggests surround needling with electro-stimulation (Crawford 1998: 19).

Deficiency Pattern Eczema – Yin/Blood Xu, Wind and Dryness.
This is chronic eczema that tends to reoccur. The skin is dry, thick and itchy. The itch is generally worse at night. The patient is often skinny, with a fine, soggy pulse, and a pale tongue (Yan and Zhu 2005: 89). To these differentiating features Crawford adds that the affected area may have a change of pigmentation, may ooze when scratched, and that there may be some desquamation of the skin. The tongue has a white coat, and the pulse will be thready, rapid, or rolling and rapid (1998: 19).

Yan and Zhu and Crawford’s patterns for the deficient pattern of eczema are different in their emphasis. Yan and Zhu call their deficient pattern “Yin vacuity, dry blood & fulminant wind” (2005: 90), while Crawford calls it “Deficiency of Xue complicated with Dryness of Wind” (1998: 19). While at first it may seem a superficial difference, it actually changes the way they develop their treatment principle and point prescriptions. While both Yan and Zhu and Crawford admit elements of Yin/Blood deficiency, Dryness and Wind, the critical difference is the origin of the Wind. It is obvious that Yan and Zhu are treating the Wind as an external pathogen, since their principle to dispel the Wind, is matched in their prescription with the point BL12 Fengmen the Wind Gate typically used to expel external Wind (2005: 90). Crawford on the other hand, acknowledging the chronic aspect of the condition, asserts through her principle and prescription, that the Wind is born of the Blood deficiency. Her principle to nourish Xue and eliminate Wind, is matched with more appropriate points for this pattern; BL17, SP10, ST36, and SP6 (1998: 19), All of which serve to build the Blood, eliminating the Wind.

Yin vacuity, dry blood, and fulminant Wind (Yan and Zhu 2005: 89).
The treatment for this pattern is to expel the Wind, nourish the Blood, and moisten the Dryness. The point prescription given by Yan and Zhu is; LI11, SP10, BL17, BL12, with modifications of HT7 for vexation (disturbed Shen from the itch), and GB31 to relieve the itch. They suggest a tonifying needle technique (Yan and Zhu 2005: 89).

Yan and Zhu also recommend moxa to treat this type of deficient pattern eczema. Moxa is to be applied at LI11, SP10, and over the centre and periphery of the affected area. In addition to these points they also moxa DU14, LI4, SP6, ST36 and any place that is itchy (2005: 89). Yan and Zhu also suggest ear points Spirit Gate, Heart, Lungs, Liver, Spleen, and any tender ear points, and using a dermal hammer over the affected area, and parallel to the spine3, until there is a little bleeding (2005: 89).

Deficiency of Xue complicated with Dryness of Wind (Crawford 1998: 19).
As mentioned above, Crawford pays more attention to the chronic, deficient nature of the condition, recognising that the Dryness of Wind is a result of a long-standing Blood deficiency. Crawford prescribes BL17, SP10, ST36, SP6, and if there is pronounced itching, PC7. Dermal hammer is suggested to break up the thickened skin, with cups applied once there is blood seeping out. Another option to treat locally is moxa cones burned directly on area of thickened skin, between 1-7 cones, each burned down a little further as tolerance to the heat develops (1998: 19). Like Yan and Zhu, Crawford also suggests ear points for deficient patients. The auricular points Shenmen, Subcortex, Adrenal, Heart, Diaphragm, and points relating to the anatomical location of the eczema. Use only 3 or 4 of these points each treatment, retaining needles for 20 minutes. Use ear seeds unilaterally in particularly chronic cases.

Conclusion
In this analysis of the treatment of eczema with acupuncture and moxibustion, I first outlined the aetiology and pathogenesis of the disease, and described the patterns of eczema. I compared these descriptions and treatments from the set text to a journal article, with particular attention given to inspection as a diagnostic method. I also noted as a comparison, the differences between treating internal and external diseases, in particular the confusion that can arise around mis-diagnosing the source of pathogenic wind.

1  Crawford includes Du14 in her additional points, to be added in the case of fever. However if included in the core set of points, could effectively expel the wind.

2  Yan and Zhu name San Yin Jiao with no point number in their text. I believe this is an error, as they previously list Yin Ling Quan (SP9) as an auxiliary point in this treatment, and go on to list SP6 (which is already in the primary prescription) as a point for prevalent damp. I have left their prescription intact with this note to point out that it should indeed be Yin Ling Quan (SP9), in conjunction with Ren12 for prevalent damp.

3  I presume they mean to dermal hammer the Bladder channel of the back.
