Here’s an example of how you can reduce a stress-response by focusing on why you chose to do something buy trihexyphenidyl 2mg otc, as opposed to what you did purchase trihexyphenidyl online pills. My patient Larry needed some help from a co-worker but he had been raised never to ask for anything trusted 2mg trihexyphenidyl. His parents always rejected his requests and made him feel invisible and not worthy enough to ask for anything. Feeling stressed, Larry mindfully noticed his inner voice criticizing him for his inaction. Larry shifted his attention from what he had or hadn’t done, to the workings of his inner child and its conditioned responses. Compassion is more easily expressed when you are reminded of the inner child’s core wounding and what strategies the child uses to cope. In Larry’s case, his inner child’s strategy was simply to not ask for any help no matter what. Once you identify the connection between fact and story you can ask yourself, “Why did I do or not do this? If you can be present to the story and say that it’s “not who I am,” then the story Mindfulness of the Inner Child: Putting It All Together • 227 remains a mental event and not something that defines you. Examine this relationship objectively to create space around what’s happening and give yourself more time to choose how you want to react. If there’s ownership happening, that is you notice yourself using a lot of “I” statements, then in knowing this, it may allow you to more consciously see the connection and not be carried along in an automatic and unconscious thought process. Finally, ask yourself, “What would it feel like if I could let go of this thought? D is for Dialogue Mindfulness is a wonderful technique that brings you into the present moment more fully, without having to change it or own it, in order to reduce the stress that comes from focusing on the past or the future. However, I have discovered that it can be difficult for people to let go of what their inner voices are saying, so that they can be fully aware of what’s happening in the present. If this is true for you, through inner-child dialogue you can develop insight into the origins of your inner voice, the one that tries to direct everything. Everything is judged against the inner child’s belief system, so that the child can feel safe, worthy and loveable. Use open-ended questions (questions that can’t be answered by saying “yes” or “no”) that begin with “Why…”. Dialoguing involves a certain sequence of steps, which you should review regularly until you really get the hang of it. However, inner-child dialogue is invaluable for understanding why you’re feeling the way you are. It brings light to the whole conditioned process so that you can transform and reframe it. The purpose of the inner-child dialogue is to discover the underlying core belief system, explore if it’s true and identify the child’s feelings. With practice, you’ll begin to change this belief system and heal the inner child so that you’ll be less reactive and less stressed in your daily life. Sometimes there are no words for it but you just feel uneasy physically or emotionally. Ask open-ended questions that can’t be answered with a simple “yes” or “no” response. If you can’t have an inner-child dialogue because you’re in public, bring up the memory of the event and your reaction to it, later, when there’s privacy and time. To realize the most benefits from dialoguing with your inner child, practice on a regular basis. E is for Empathy It’s vital that you bring a sense of empathy, compassion and understanding to your inner-child dialogues. After you have been having regular inner-child dialogues for a while, you’ll have discovered what the child’s belief system is and what it needs to feel safe, loved and worthy. With this knowledge, you’ll begin to reframe Mindfulness of the Inner Child: Putting It All Together • 229 the belief system. This reframing is basically just offering a different perspective, an alternate way to view life, so that the child will progressively have a more constructive, positive and healthier belief system. You, as the voice of the adult, can repeat positive affirmations (positive statements that are personal, reassuring and uplifting) or action statements that reflect what you intend to do in order to finally meet the inner child’s previously unmet feelings and needs. The adult in you can confirm that, as much as is possible, you’ll do what needs to be done in order to take care of whatever is worrying the child. You’ll begin to feel a sense of relief as the inner child starts to feel better as a consequence of knowing that it’s being understood and supported. Through empathic support, you’ll have the ability to transform the inner child’s reactions and you’ll experience less stress as a result. You can jump right to this shortened version, or summary, if you don’t have time to hold a longer dialogue during a stressful event. Here’s what you need to do in a shortened, or summary version, of an inner-child dialogue: • Describe the event • Express what the inner child is feeling • State the belief • Provide some reframing • State the actions and positive affirmations Do the shortened dialogue throughout the day or when you encounter troubling feelings, thoughts or events. The complete process of Awareness, Body and Breath, Connection, Dialogue and Empathy should still be practiced when there’s time and privacy to do so. It’s important to create a formal designated time to practice inner-child dialoguing and to do it as often as you can. You’ll need to hold frequent dialogues in order to become familiar with the core wounding, coping strategies and needs of your inner child. However, the real issue is how you deal with your mind on a moment-to-moment basis during a stressful event. You can either bring your attention to the breath or intentionally breathe in a relaxed manner. This, initially, may be all that you can do in the heat of a really stressful moment. However, as you become more experienced in the practice of mindfulness and more familiar with the inner child and its underlying feelings and needs, you’ll be able to apply some of the other techniques that you’ve learned. Try one or more of the following approaches during a stressful moment, but remember that they’ll all be much more effective and easier to do if you’re regularly practicing, mindfulness, relaxed breathing, and inner-child dialoguing: • Bring your attention to the physical sensations and rest in the body knowing that you’re directly experiencing how the inner child feels. Mindfulness of your thought process is a wonderful way to step out of the storyline and bring awareness to how your mind works. Remember, the story that Larry told himself: I bought the suit and now I’m terrible and will be penniless. Mindfulness of the Inner Child: Putting It All Together • 231 It was Larry’s story that was stressful, not the fact that he bought a suit. Once you’ve been practicing mindfulness and inner-child dialogue for some time and have truly begun to understand that the stressful mental states that you’re experiencing are fabrications of the mind, 232 • Mindfulness Medication invented stories based on your childhood belief system, you can be present in any given moment in a very freeing way. The qualities of any internal or external stressful sensation or event that you experience are all creations of your mind.

Sulfonamides chemically synthesized beginning with Domagk’s Prontosil rubrum were widely used as efficient and inexpensive antibacterial drugs for the treatment of both gram-positive and gram-negative pathogens, and they had a deep impact on the fate of Europe. In December 1943, British Prime Minister Winston Churchill had just completed a complex series of meetings, among them the fateful conference with Franklin D. Eisenhower in Tunis to discuss the D-day landings when he contracted a severe case of pneumonia. His doctor, Lord Moran, decided to treat his important patient with a new drug, a sulfonamide. The treatment was successful, and there is little doubt that the novel sulfa drug defeated the pneumonia and probably saved the life of this important European leader. The introduction of sulfonamide into clinical practice can be regarded as the birth of chemother- apy as defined by Paul Ehrlich. Through the years, however, the term chemotherapy has come to mean treatment with cyto- static agents in the treatment of tumors. The original distinction between chemotherapeutics, chemically synthesized antibacte- rial agents such as sulfonamides, and antibiotics produced by living organisms has been difficult to retain, not least because medicinal chemists have been increasingly skillful in modifying antibiotic structures: for example, to escape resistance develop- ment (Chapter 4). Instead, the word antibiotics has come to comprise all selectively acting antibacterial agents, even though the meaning of the word is not altogether correct when applied to antibacterial agents such as sulfonamides, trimethoprim, and linezolide. The original observation was made by Alexander Fleming at the bac- teriological laboratory of Saint Mary’s Hospital in London. In his research, Fleming was interested in staphylococci, particularly in the color and form of staphylococcal colonies on an agar plate. He had a hypothesis, which could never be verified, that there was a connection between the appearance of staphylococcal colonies and their pathogenicity. Among his staphylococcal plates, on one occasion, Fleming observed a plate with a large patch of mold growing on it (Fig. The staphylococcal colonies on the same plate seemed to maintain a distance from the mold, not growing in its vicinity. A replica of the original plate of Alexander Fleming showing a patch of Penicillium mold and Staphylo- coccus colonies seeming to avoid the mold patch. This phenomenon caught Fleming’s attention, and one of the many biographies about him (Gwyn Macfarlane, Alexander Fleming, The Man and the Myth, The Hogarth Press, London, 1984) describes how on a sunny September morning in 1928 on the lawn outside the laboratory, he showed the plate to two fellow bacteriologists. None of the three could explain the phenomenon on the plate or at all imagine that at that moment they had a tryst with destiny. The interpretation of this phenomenon would open the way for the greatest triumph of scientific medicine: the control of bacterial infections with selectively acting drugs. The diffusible agent inhibiting bacterial growth on the plate in the vicinity of the mold was named penicillin by Flem- ing, and together with its many derivatives, it would eventually become dominant among antibiotics in the treatment of bacterial disease. By its mechanism of action (Chapter 4), penicillin cannot act on resting nondividing bacterial cells—only on growing bacteria. This circumstance, together with the property of mold to grow much more slowly than staphylococci, led to the conclusion that penicillin could not have been discovered in the manner described. If the agar plate was already polluted with mold cells when Fleming streaked it with the staphylococci he was interested in, they would have grown out to be insusceptible to penincillin long before the mold had grown out enough to produce penicillin. The mold could also not have grown out to form a colony before inoculation with bacteria, since no microbiologist would use a contaminated agar plate. This microbiological mystery seems to be explained by a fantastic sequence of coincident circumstances. Fleming seems to have inoculated the agar plate at the end of the month of July and then left for summer holiday in Scotland, forgetting that the plate ◦ was on the bench and thus not placed in the 37 Cincubator. The weather records for London from 1928 show that the first week of August that year was unusually cold, followed by hot summer weather. Mold cells grow faster than bacteria at low temperatures, which means that a mold colony could have formed during the cold spell, while the staphylococci caught up in the following warm period, then to meet with the penicillin produced and diffused out from the mold, forming the famous zone. This could be looked at as an example of serendipity, a scientist finding something quite significant without having looked for it (Fig. The First Therapeutic Trial Fleming identified the penicillin-producing mold as Penicillium notatum and showed that extracts from cultures of it inhibited the growth of several pathogenic bacterial strains. Fleming left this research after about half a year, however, with a report delivered on May 10, 1929 and published in the June issue of British Journal of Experimental Pathology (No 3, volume 40). In this paper the therapeutic possibilities of penicillin are only mentioned in connection with the treatment of infected wounds. ItisanenigmainthehistoryofmedicinewhyFlem- ing left research on penicillin so quickly. Fleming’s basic observations on penicillin were developed further toward an antibacterial remedy only after a period of 12 years, in 1940. Rediscovery of Penicillin by a Basic Scientific Approach In 1940, Australian-born Howard Florey, a professor of pathol- ogy, German-born Ernst Chain, a biochemist, and British-born Norman Heatley, a biochemist, all three at Oxford, England, began scientific studies on penicillin. Fleming had shown that penicillin interfered with the bacterial cell wall, and the three men wanted to investigate agents that had the ability to dissolve the murein of the cell wall in parallel with the enzyme lysozyme, the mechanism of action of which Florey had just studied. Chain first thought of penicillin as an enzyme, but very soon during purifi- cation, it emerged as a small molecule. It is interesting to note that it was purely a scientific interest in bacterial cell wall degradation that led the three scientists to take up study of the phenomenon discovered by Fleming. The realization of therapeutic possibilities led to what has been called the most important pharmaceutical experiment ever carried out. It began on Saturday morning, May 25, 1940, in Oxford when Howard Florey injected eight laboratory mice intraperitoneally, each with 108 cells of S. One hour later, four of the eight mice were injected subcutaneously with 10 mg of a brown powder dissolved in water. At half past three on Sunday morning, all four of the mice injected with the brown powder solution were healthy and agile, whereas the other four were dead. Heatley was the co-worker who devised a purification method and also the method needed to assay penicillin activity. The penicillin produced quickly performed as a dramatically efficient remedy against bacterial infections. It immediately provided great relief in the treatment of infected war wounds, and very soon it found its way into clinical medicine in general. Alexander Fleming, Howard Florey, and Ernst Chain were awarded the Nobel Prize in Physiology or Medicine in 1945. Today, penicillin is produced in copious amounts all over the world using industrial procedures that are so efficient that the final product is pure enough for direct use in pharmaceutical products. The large global production of penicillin today has led to it being regarded as a commodity on the scale of coffee and tea. Organic chemists have succeeded in the total synthesis of peni- cillin, but industrial production today takes place in large tanks where penicillin-producing mold cells are grown. Betalactams The penicillin isolated originally, penicillin G, is acid labile and has to be administered parenterally lest it be destroyed by stomach acid.
