This virus is believed to have a causative role in the induction and/or maintenance of Kaposi sarcoma through perturbation of focally released cy to kines, growth fac to rs, and angiogenic agents. Clinical Features Tree diferent clinical patterns of Kaposi sarcoma have been described (Figures 4-22 to 4-25). Kaposi initially de The second pattern of Kaposi sarcoma was identifed in scribed the condition in 1872 as a rare skin lesion, pre Africa, where it is considered endemic. It is typically seen in dominantly in older men living in the Mediterranean basin the extremities of blacks. The clinical reddish-brown nodules primarily in the skin of the lower course is prolonged, and the overall prognosis is only fair. Oral le The third pattern of Kaposi sarcoma has been seen in sions are rare in this type. This classic form has a rather long patients with immunodefciency status, including patients indolent course and only a fair prognosis. Of signifcance is that oral lesions may be the initial site or the only site of involvement. Kaposi sarcoma has been de scribed in most oral regions, although the palate, gingiva, and to ngue seem to be the most commonly afected sites. Clinical presentation of oral Kaposi sarcoma ranges from • Figure 4-25 Advanced Kaposi sarcoma of the gingiva. This type difers from the Kaposi sarcoma may have other oral problems concomi other two forms in several ways. Skin lesions are not limited tantly, such as candidiasis, hairy leukoplakia, advancing to the extremities, and they may be multifocal. Visceral organs may also be involved, and a younger age His to pathology group is afected. The clinical course is relatively rapid and Early lesions of Kaposi sarcoma may be rather subtle, being aggressive, and the prognosis is correspondingly poor. Diferential Diagnosis Clinical considerations include hemangioma, erythroplakia, melanoma, and pyogenic granuloma. Another remarkable look-alike, known as bacillary angioma to sis, mimics Kaposi sarcoma both clinically and microscopically. This condition is cured with erythromycin or tetracycline • Figure 4-26 Early Kaposi sarcoma showing a subtle increase in therapy. Bacillary angioma to sis is uncommon in the skin the number of capillaries and extravasated red blood cells. Other types of chemotherapy directed against angiogenesis, and cy to kine pathways may also be benefcial. Surgery has been useful on localized lesions, as well as low-dose radiation and intralesional chemotherapy. Improvement in the underlying immunosuppression may help to reduce the size and number of lesions. Vitamin B Defciencies Etiology In various areas of the world, especially those with poor socioeconomic conditions, vitamin B defciencies may be relatively common because of inadequate dietary intake. Vitamin B defciencies may involve one or several of the water-soluble B complex vitamins. Decreased intake through malnutrition associated with alcoholism, starva tion, or fad diets may lead to clinically apparent disease. Others (vitamin B12 and folic acid) are in detailed in the following sections on anemia. Diagnosis and Treatment Signifcant oral changes have been well documented in de Diagnosis of B complex defciencies is based on the his to ry, fciencies of ribofavin (aribofavinosis), niacin (pellagra), clinical fndings, and labora to ry data. Replacement therapy folic acid (one of the megaloblastic anemias), and vitamin should be curative. Pernicious Anemia Clinical Features Etiology In general, oral changes associated with vitamin B defcien Pernicious anemia is essentially a defciency of vitamin B12 cies consist of cheilitis and glossitis. Pernicious anemia results from the inability to papillae, and patients complain of pain, tenderness, and transport vitamin B12 across intestinal mucosa because of a burning (Figure 4-29). This intrin In addition to these oral changes, ribofavin defciency sic fac to r is normally complexed to vitamin B12, making the results in keratitis of the eyes and a scaly dermatitis focused vitamin available to mucosal cells for absorption. Niacin defciency is mune response directed against the intrinsic fac to r producing associated with extraoral problems as well. The “four Ds” of parietal cells in the gastric mucosa is believed to be the probable niacin defciency are dermatitis, diarrhea, dementia, and mechanism responsible for pernicious anemia. The most striking and consistent feature is a sym consists of atrophic gastritis, achlorhydria, neurologic changes, metrically distributed dermatitis that eventually shows megaloblastic bone marrow, and macrocytic anemia. The glossitis in this defciency may be severe and may extend to Clinical Features other mucosal surfaces. In more severe cases, central nervous sys malities, including diarrhea and the general oral lesions tem manifestations (headache, dizziness, and tinnitus) described previously. Vitamin B12 defciency shares many of and gastrointestinal manifestations (nausea, diarrhea, and s to matitis) may be noted. Oral complaints center on the to ngue, with patients re porting pain and burning as typical symp to ms. The resul tant smooth, red appearance has been referred to as Hunter’s glossitis or Moeller’s glossitis. Angular cheilitis, oral candi diasis, recurrent oral ulcers, and a difuse erythema to us mucositis have been noted. Diagnosis The clinical picture of pernicious anemia can be only pre sumptive of this disease. Diagnosis is based on labora to ry demonstration of a megaloblastic, macrocytic anemia. Treatment Parenteral administration of vitamin B12 is curative for this condition. Increased risk of the development of gastric car cinoma is associated with the chronic atrophic gastritis that may occur in pernicious anemia.

This is a particularly frustrating problem for The mechanism by which such a varied group of fac to rs both patient and clinician, because usually no clear-cut causes symp to ms of burning mouth syndrome is com cause is evident once the previously stated conditions are pletely enigmatic; more attention has recently been placed ruled out, and no uniformly successful treatment is present.

It is apparent that burning mouth syndrome often is difcult to decipher clinically. Symp to ms of pain occurs in a diverse group of patients, although many indi and burning appear to be the result of one of many possible viduals will be sufering from depression or anxiety. The following fac to rs have been cited as having possible etiologic signifcance: Clinical Features • Microorganisms—especially fungi (Candida albicans) this condition typically afects middle-aged women.

Proliferation of Langerhans cells (histiocytes), which are normally found within the epidermis b. Melanocytic tumors include congenital nevi (birth marks, giant ones have increased risk of melanoma), nevocellular nevi (common moles with proliferating nevus cells; subclassified as junctional, compound, and intradermal), dysplastic nevi (larger, more irregular, and with more pigment variation than common moles, cy to logical and architectural atypia, may be part of au to somal dominant nevus syndrome with increased risk of melanoma if multiple), and malignant melanoma. Malignant melanoma (risk fac to rs: sun exposure, fair skin, dysplastic nevus syndrome) has a rapidly increasing incidence (peak middle age and older) and prognosis ranging from excellent (thin lesions that can be completely excised) to poor (metastatic lesions, often arising in primary sites with tumor thickness greater than 1 mm). In general melanomas cause asymmetric, irregular, large-diameter macules, papules, or nodules with variegated color, found most often on the upper back of men and the back and legs of women. Subtypes include lentigo maligna melanoma (best prognosis, face or neck of older individuals), superficial spreading melanoma (most common type, horizontal growth pattern), acral-Ientiginous rnelanoma (palms, soles, and subungual area of dark-skinned individuals), and nodular melanorna (vertical growth pattern with worst prognosis). Benign epidermal and dermal lesions include acanthosis nigricans (thickened, hyperpigmented skin in axillae and groin that may be associated with internal malignancy), seborrheic kera to ses (very common benign squarno-proliferative tan to brown coin-shaped plaques that appear "stuck on" the trunk, head, neck, and extremities of middle-aged end elderly people), and psoriasis (well demarcated erytherna to us plaques with silvery scale and pinpoint bleeding after scale removal commonly involving knees, elbows, and scalp; micro shows epidermal hyperplasia, parakera to sis, and Munro abscesses; genetic component and associations with arthritis, enteropathy, and myopathy).

A career in Permanent Make Up is not only exciting, varied and financially lucrative, but it is also incredibly fulfilling. Being a skilled technician, you have the power to make a positive difference every single day both to the lives of your clients and to yourself, by advancing your own personal journey of growth and development. In order to be successful in this highly competitive industry, you need to learn from the best. Our highly progressive training course will equip you with the knowledge, skills and support that you need to excel in Micropigmentation as well as providing you with national accreditation. Teaching for us means sharing knowledge, experience and a genuine passion to an art that we have dedicated our lives to. It means supporting you to develop technical skills and trying to get the best out of you. While some students learn quickly, others will need more time; you should not compare yourself to your colleagues during the first few weeks of your learning as everyone learns at different rates. It may be the case that you haven’t been in a classroom situation for a very long time, or you may be a perfectionist who becomes frustrated when you cannot grasp something new immediately and you have to start out as a beginner. During this course you will go through a rollercoaster of emotions and it is to tally normal. We are here to offer you guidance and support and to help you become the very best technicians in the world. Work hard, be patient and embrace the team spirit of learning with others to become colleagues and not competi to rs. We would like to thank you for choosing to train with us and have no doubt that this first platform to permanent make up will provide you with the foundations to build a long, skilled and successful career in this wonderful industry. It’s easy to become frustrated and angry when you can’t be perfect at something that initially may appear to be very easy, but listen to your trainers and be to tally open to their suggestions. Don’t take offence at their First Platform to Permanent Make Up critique as it’s purely to help you be the very best you can be. Our experienced trainers will not let you do anything on a client if they don’t feel that you’re ready. If you aren’t ready, watch the trainer take over, and use any free moment to practice on the mats provided – practice really does make perfect. It is essential that your 120 hours pre-study is completed before entering the classroom. If you haven’t got to grips with the fundamental theory of Permanent Make Up, you’re not ready to work in a practical environment where knowledge of hygiene and legislation is vital. The models on the course are real people and you should treat them with the same respect, courtesy and understanding that you would a regular client in your own clinic. If you feel nervous, if an issue arises that you feel uncomfortable with (such as they are bleeding a lot or you can’t get the colour in) or if there is something that you need to say to your trainer that may be inappropriate for your client to hear, ask to speak to your trainer privately and do not have the conversation in front of the model. Please note also that swearing, discrimina to ry and offensive language/behavior will not be to lerated. While we provide you with the to ols and methods to start your own brilliant business in Permanent Make Up, it is forbidden to plagiarize or copy any literature/images belonging to the Tracie Giles Ltd brand. Have fun and make the most of the opportunity to learn with some of the very best and most experienced Permanent Make Up trainers in the world! Client Satisfaction Surveys Appendix A: Medical His to ry and Consent Forms Appendix B: Pre-Procedural Advice Appendix C: Aftercare Advice Appendix D: Risk Assessment What is Permanent Make Upfi The pigments consist of organic and inorganic minerals in a glycerin base, all specifically selected for their hypo-allergenic qualities. It is sometimes described as a ‘cosmedic’ procedure, owing to the fact that it can be used to create perfectly realistic hair-by-hair brows, beautifully shaped lips and add First Platform to Permanent Make Up definition to the eyes for cosmetic purposes but also as a treatment for medical reconstruction and enhancement, providing that finishing to uch to reconstructive surgery after, for example, breast cancer or breast surgery where the areola has been removed/dis to rted. The Stages Involved • Preliminary Consultation • Patch Test • Pre-Drawing • Procedure • Re to uch • Annual Re to uch We would recommend that the client is seen for a preliminary consultation prior to starting the procedure. This time should be spent listening to what the client wants to achieve and for you to decide firstly whether your client is a suitable candidate for treatment (for example, a lip treatment will not be suitable for darker skin to nes as we will later discuss) and also whether you believe that you can successfully manage your clients expectations and that what they desire is appropriate. If there is any chance that the final outcome of the treatment is not an improvement, we would never recommend carrying out the procedure. A consultation will also allow for you to give the client a patch test (usually a small dot of pigment behind the ear) to ensure that when they come for their treatment, they have no allergy to the pigment. The next stage is carrying out the actual treatment which will be discussed in more depth later during this course pack, but in essence is comprised of the initial pre-drawing and then the actual cosmetic tat to oing procedure. When you are still in the early stages of your Permanent Make Up career, it is important that you allow yourself enough time to carry out your treatment so that you do not feel under pressure or rushed. We generally recommend First Platform to Permanent Make Up that you block out a 2 hour interval for the initial treatment to make sure that you achieve the optimum results. As a beginner, it should certainly not take you any time shorter than 2 hours, and you may find that you require a longer period of time to produce the desired outcome. The client will be required to return after 2-12 weeks (depending on the treatment method) to complete the process, otherwise known as their re to uch. The process will not necessarily be finished until the client has had this re to uch, as some skins will not sufficiently retain the pigment from the initial session. Moreover, it is advisable to start off ‘lighter’ in the first treatment as it is much easier to intensify and add to the colour in the second treatment than to remove a colour that is to o dark for the client. Some clients may even need 2 re to uches, although this is not common for experienced technicians. To keep the colour looking fresh and fabulous, we would suggest that on average, your client returns every 12 months for a yearly re to uch, but if it is correctional/medical work that has been carried out, this time period may vary. The Importance of Hygienic Practices Effective use of hygiene practices are necessary in the salon to prevent cross-infection. Some germs are harmless, some are even beneficial, but others present a danger to us because they cause disease. Cross-infection occurs when microorganisms capable of causing disease and/or infection are transferred through personal contact or by contact with infected to ols that have not been properly cleaned and sterilised. When you carry out your consultation it is important to check for any type of contraindication or signs of infection. Infection Infection occurs when the body becomes contaminated by micro-organisms, these usually include bacteria, fungal or viral causes. The reaction to the infection will depend on its cause and the part of the body which is infected. Secondary infection can occur if bacteria penetrate an existing injury or compromised skin that is already infected by a viral or a fungal infection. The germs which cause disease are usually spread by: • Unclean hands • Contaminated to ols/instruments • Sores and pus • Discharges from the nose and mouth • Shared use of items such as to wels and cups • Close contact with infected skin cells • Contaminated blood and tissue fluid Infectious diseases that are contagious are a contraindication to beauty treatments and clients presenting with a contraindication of this nature should be referred for medical attention. Clients with skin disorders that have caused the skin to crack and inflame should also not be treated as they are more susceptible to secondary infection. First Platform to Permanent Make Up Hygiene practices must always be strictly adhered to for every service offered as sometimes people have a contraindication they are not aware of. Sanitation and Sterilisation Refers to any procedure undertaken in the salon to remove contamination and reduce the risk of infection. Specific methods are required to ensure effective sanitisation of to ols, equipment and implements have taken place. As a permanent make up practitioner, you have a duty of care and it is absolutely imperative that you provide a clean and sanitised environment and equipment for your client. It is very difficult to maintain sterile conditions as once the items have been exposed to the air they are no longer classed as sterile. Articles that have been cleaned, sterilised and s to red hygienically are safe to use on clients. Methods of Cleaning Tools and Equipment: • Disinfectant inhibits the growth of disease-causing organisms (except spores) using chemical agents. Disinfectants only reduce the number of organisms however this is usually sufficient for maintaining hygienic conditions.

Rare cases of optic neuritis and demyelinating dis­ eases, including multiple sclerosis have been reported. Anti-integrins-Two monoclonal antibodies are avail­ able that target integrins, decreasing the trafficking of cir­ culating leukocytes through the vasculature and reducing.

Intestinal obstruction-Narrowing of the small bowel endoscopic findings include aphthoid, linear or stellate may occur as a result of infammation, spasm, or fbrotic ulcers, strictures, and segmental involvement with areas of stenosis. Patients report postprandial bloating, cramping normal-appearing mucosa adjacent to infamed mucosa. This may occur in patients 10% of cases, it may be difficult to distinguish ulcerative with active infamma to ry symp to ms (as above) or later in colitis from Crohn disease. Granulomas on biopsy are pres­ the disease from chronic fibrosis without other systemic ent in less than 25% of patients but are highly suggestive of symp to ms or signs of infammation. Penetrating disease and fistulae-Sinus tracts that often is obtained in patients with suspected small bowel penetrate through the bowel, where they may be contained involvement. Penetration through the bowel can result in an may identif bowel wall thickening and vascularity, muco­ intra-abdominal or retroperi to neal phlegmon or abscess sal enhancement, and fat stranding. Capsule imaging may manifested by fevers, chills, a tender abdominal mass, and help establish a diagnosis when clinical suspicion for small leukocy to sis. Fistulas between the small intestine and bowel involvement is high but radiographs are normal or colon commonly are asymp to matic but can result in diar­ nondiagnostic.

Surgical therapy is required for symp­ to matic fstulas that do not respond to medical therapy. Differential Diagnosis Fistulas that arise above (proximal to ) areas of intestinal stricturing commonly require surgical treatment. Chronic cramping abdominal pain anddiarrhea are typical of both irritable bowel syndrome and Crohn disease, but radiographic examinations are normal in the former.

Current treatment guidelines recommend common, a trial off dairy products is warranted if flatu­ lence or diarrhea is a prominent complaint. Antibiotics-Antibiotics also are widely used by clini­ diet, ie, no raw fruits or vegetables, popcorn, nuts, etc. Parenteral vitamin B 2 (1000 meg subcutaneously otics may reduce inflammation through alteration of gut 1 per month) commonly is needed for patients with previous flora, reduction of bacterial overgrowth, or treatment of ileal resection or extensive terminal ileal disease. Enteral therapy-Supplemental enteral therapy via ciprofoxacin (500 mg twice daily), or rifaximin (800 mg nasogastric tube may be required for children and adoles­ twice daily) are commonly administered for 6-12weeks. Corticosteroids dramatically suppress the patients with active disease and progressive weight loss or those awaiting surgery who have malnutrition but cannot acute clinical symp to ms or signs in most patients with both small and large bowel disease; however, they do not alter to lerate enteral feedings because ofhigh-grade obstruction, high-output fistulas, severe diarrhea, or abdominal pain.

Symp to matic Medications budesonide (6 mg/day) may be used for up to 1 year to There are several potential mechanisms by which diarrhea maintain remission. Budesonide is superior to mesalamine may occur in Crohn disease in addition to active Crohn but somewhat less effective than prednisone. A rational empiric treatment approach often yields because budesonide has markedly reduced acute and therapeutic improvement that may obviate the need for chronic steroid-related adverse effects, including smaller corticosteroids or immunosuppressive agents. Involvement reductions of bone mineral density, it is preferred to other of the terminal ileum with Crohn disease or prior ileal systemic corticosteroids for the treatment of mild to mod­ resection may lead to reduced absorption of bile acids that erate Crohn disease involving the terminal ileum or may induce secre to ry diarrhea from the colon.
