Exploring the Risk Factors, Diagnostic Tests, Outcome Measurements and Exercise Treatment *,1,2 1 2 Konstantinos Papadopoulos, Demetris Stasinopoulos and Dimitar Ganchev 1 School of Sciences, Department of Health Sciences, Physiotherapy programme, European University of Cyprus 6, Diogenes Str. Studentski grad, 1700, Sofia, Bulgaria Abstract: Background: Literature has shown a growing number of published studies on Patellofemoral Pain Syndrome every year. The increasing evidence base has revealed a significant number of reviews which makes it confusing for clinicians and researchers to choose from the best evidence. This study aimed to gather the reviews on Patellofemoral Pain Syndrome and provide information about the most common clinical tests, risk factors, exercise treatment and outcome measures. In addition, secondary questions aimed to report the study settings and patient characteristics of the primary included studies. Methods: Studies eligible for this Review of Reviews were those published from 1993 to July 2013. The keywords for the four research topics were a) risk factors; b) exercise treatment; c) diagnostic clinical tests and d) psychometric outcome measurements. At first, the level of evidence was graded and then the methodological quality of each review was assessed. After excluding duplicates, 144 primary studies were screened to answer the secondary questions. The quadriceps strength deficits are still the only evidence based risk factors along with the dynamic malalignment of the lower limb. More research is still required on strength and flexibility deficits of other lower limb muscles. The quadriceps-based exercises are still the only ones to have strong evidence together with hamstrings, quadriceps, gastrocnemius and anterior hip muscles stretching. Finally, the usage of Activities of Daily Living Scale is recommended as the best outcome measure. Conclusion: There is no evidence on whether the above treatment and assessment methods should be used in sedentary people or differently across population groups or gender. Keywords: Anterior knee pain, clinical tests, exercise treatment, outcome measures, patellofemoral pain syndrome, participant characteristics, risk factors. Researchers have identified this problem and studies on healthcare interventions every year [1]. One started gathering these studies in systematic reviews in order category of healthcare intervention that contains nebulous to appraise and summarise evidence [3]. As the number of reviews began to grow, so have the number of protocols for the *Address correspondence to this author at the School of Sciences, conduct of systematic reviews. One such an example is the Department of Health Sciences, Physiotherapy programme, European Cochrane Collaboration which in 2008 included only one University of Cyprus 6, Diogenes Str. Since then, eight more reviews have been Tel: +35722559562; Fax: +35722713013; published. The secondary aim was to determine the context processes to identify and appraise reviews, describe the and characteristics of participants in included studies. The keywords for the four research topics were a) risk factors; b) exercise the protocol and the questions of the current study were treatment; c) diagnostic clinical tests and d) psychometric designed beforehand; however the protocol was not outcome measurements. The second level of screening criteria in order to answer a specific questions, were involved the screening of abstracts, and was conducted by two selected [21]. Along with the abstracts, full-text articles Only reviews in English language were obtained. When, even after analysing the full text, the eligibility of an article remained uncertain, it was planned to reviews (country) was imposed. Therefore, a two-stage be either patients of National Health Service or evaluation was performed in each review assessment. At first, patients visiting a private clinic or private practice the level of evidence was graded [3] and then the physiotherapists. This framework is a widely used critical appraisal and evidence hierarchy which has the advantage of Study design: Studies with no clear search strategy and being simple and clear to use. Studies that did not report clear graded from 1++ to 2depended on the study design. According to Clarke [28], the methodological conduct of a Case definition: Studies focusing on other named knee review plays an important role in the successful interpretation of pathologies (such as Osgood Schlatter disease, Sinding results from systematic reviews. In the tool consists of 11 items and was created to assess the earlier years (1955 to 1980) surgical interventions were more methodological quality of systematic reviews and found to have common than non-operative treatment and most of the articles good inter-rater reliability (Kappa scores >0. Each item is given a score of 1 if the specific criterion is met, or a score of 0 if the criterion is not met, is unclear, or is not applicable. Levels 0-3 can be considered as low quality, 4-7 as identify additional reviews [25]. Consequently, the study also set out to identify After screening titles and abstracts 31 reviews remained. In case 1 about clinical tests and risk factors and 1 regarding all 4 of any disagreement regarding grading of evidence, quality components of this study. Study Characteristics Data Collection Process Examination of the 13 reviews that were excluded after Titles and abstracts were screened for eligibility full texts were obtained revealed 11 with no clear according to the aforementioned inclusion and exclusion methodology about how the included studies were gathered, criteria. When the appropriateness of some reviews was not one review with combined exercise treatment and other clear, the full text was obtained. Studies could be funded question, therefore in some cases the subject matter related by an external source or not. Supplementary Material 2 shows all 31 full-text Risk of Bias in Individual Studies assessed reviews, their topic, design and which reviews were included and which not. Critical Appraisal the level of evidence for the selected reviews is Summary Measures presented in Table 1. No level of evidence was reported for the four reviews which were not systematic or meta-analysis. Data with and without significant differences were the results showed two clinical test reviews of high quality presented in this study.

One of the two systematic reviews tightness, mediolateral patellar mobility, tight quadriceps, also reported meta-analysis on one clinical test [34]. The most common the other three studies were systematic reviews with were the q-angle, tilting and patellar compression. Two of them [9, 17] were high quality angle and tilting tests were reported by Fredericson and systematic reviews of case control and cohort studies whilst Yoon [31] and Selfe [33] and were found to have low Lankhorst et al. The first authors the last review was the highest and should be taken into reported low sensitivity and specificity. Only Fredericson and Yoon [31] reported functional declaration any conflict of interest. However, they also found important case control and cohort studies [9] reported that a larger Qdisadvantages across the studies i. However no flexibility tests were reported as risk factors and they called for more research in high-risk Risk Factors groups such as athletes and military populations. Two of them [31, 33] could not enough evidence for flexibility deficits components. Larger q-angle, muscle strength deficits, muscle reported biomechanical and neuromuscular risk factors and not tightness and joint and patella laxity were the components structural (static) risk factors. Most of the risk factors showed contradictory results and totally different Exercise Treatment methodology across the primary studies. This explains why in these two studies comparison across the included studies Eight reviews met the inclusion criteria of exercise was difficult if not impossible. Two of the anthropometric risk factors such as body weight, age and reviews were not systematic; the one was narrative [32] and sex, however the evidence was limited and in some cases the other was a critical review [33], respectfully. Additionally, three One review was entitled as systematic with no metareviews were identified as high quality meta-analysis or analysis [37]. As mentioned before the review from Selfe [33] was the other two studies were identified as high systematic identified to have low level of evidence and had only one out reviews of case controls or cohort studies. Contrasting To answer the secondary questions of this review only results were reported between Frye et al. The former reported significant results between were excluded from this section were the following: supervised and not supervised exercise prescription whilst Malanga et al. The 14 systematic reviews included Only two of the reviews [13, 14] included information about 213 studies; 69 duplicates were identified and 144 primary whether stretching is beneficial and which structures studies were screened to answer the secondary questions of clinicians should aim for greater flexibility. This backtracking search revealed 43 studies that the Iliotibial band is one of these components. In terms of the research setting, there Three studies were identified in this section were 21 studies which did not report where the research was (Supplementary Material 6). The earliest one was the review conducted; however, most of the studies (67) took place at from Selfe [33] which did not focus on outcome measures university laboratories and not in clinical environments. As mentioned previously the study was a critical rest were conducted either in military bases, research centres review with low methodological evidence (1/11). Most of the studies also did not mention the the result revealed many contradictions on specific muscle patients general activity levels or sport at all. However, hamstring flexibility) and the only risk factor that they there were 40 studies which reported that their patients were agreed on was the quadriceps strength deficit and the low athletic or participated in sports such as running and dancing. Recent systematic reviews [9, 17] In addition to those 40 studies, 14 studies included military also revealed contradictions on strength and flexibility risk populations which researchers assume to be athletic as well. It is that most of the patients were from military studies where worth mentioning that these risk factors are for athletes with large numbers of participants were recruited. Moreover, researchers call for more research in however, 1888 women were recruited in the other 114 athletic or military population. These questions were about the number of participants, there was no evidence that strengthening the hip muscles the systematic reviews used, the gender and the participants could be beneficial. Generally, this RoR literature as many methodological contradictions between showed that the recent reviews stronger evidence compared primary studies were observed. In addition, fundamental to the earlier ones, because the level of evidence and principles such as whether exercise is better than no exercise methodological quality of the reviews have been positively were still debated. An analytical discussion of all components of this still not enough evidence to report that patients would systematic RoR is provided below.

Keywords: Cholesterol level, Recurrent oral ulcer, Assesment Introduction Ulcer is defined simply as a break in the skin or mucous membrane with loss of surface tissue, disintegration and necrosis of epithelial tissue [1]. The recurrent oral ulcers are the most common oral mucosal lesions characterized by the repeated formation of benign and non-contagious oral lesion that can be observed by the dentists [2]. It is usually occurring on nonkeratinized or poorly keratinized surfaces of the oral mucosa such as labial and buccal mucosa, maxillary and mandibular sulcus, unattached gingiva, soft palate, floor of the mouth, and ventral surface of the tongue [3]. Oral ulcers are one of the various developing conditions within oral cavity that is associated with painful lesions, They may be fungal, bacterial, viral infection-associated or noninfection-associated conditions. The standard treatment protocol for these oral ulcers includes the elimination of etiologic factors, pain reduction, and promote normal healing [4]. They can be classified as acute or chronic according to their presentation *Corresponding Author: Basma Ezzat Mustafa Aland progression.

Blood cholesterol level of the patient was taken and analysed by using multi parameter system meter Discussion device (Human Sens Plus). Patient blood pressure was Since the recurrent oral ulcers are the most common measured when the patient is sitting during rest, using chronic inflammatory disease of the oral mucosal tissues sphygmomanometer device. It was measured twice with characterized by the presence of single or multiple ulcers interval of 5 minute between the two measurements then persisting and recurring for variable period of time [25]. Everything noted down on the oral medicine case sheet and the picture of the oral ulcers were In normal conditions, mucous membrane are protected taken as a proof.

Ezetimibe, brates, and nicotinic acid represent the second-choice drugs to be used in combination with statins if lipid targets cannot be reached. However, the costs for these new therapies made the costeffectiveness debate more complicated. Introduction Cholesterol is a fatty substance necessary for the proper functioning of the body. In fact, it participates in the synthesis of some hormones and vitamin D, and it is a constituent of cell membranes. Cholesterol is produced by the liver but can also be introduced with the diet (foods rich in animal fats such as meat, butter, salami, cheese, egg yolk, and liver) [1]. Cholesterol is transported through the blood thanks to a particular class of particles called lipoproteins. There are four types of lipoprotein classied by density, which is inversely proportional to the amount of cholesterol present [1]. This process, called atherosclerosis, can lead to the formation of true plaques (or atheromas) thus altering blood ow, or even block it completely. When the heart does not get enough oxygen-rich blood, angina pectoris may developa condition characterized by chest pain, which can radiate to the arms or jaw, usually at the same time as effort or stress. In addition, the plaques may detach and form a thrombus, which can cause a sudden stopping of the bloodstream [4]. For all these reasons, with dyslipidemia, it is important to identify a desirable cholesterol value that should be reached or not exceeded in order to maintain cardiovascular risk within acceptable limits. High cholesterol levels do not produce direct symptoms: many people ignore the fact that they suffer from hypercholesterolemia. However, cholesterol can be easily measured with a simple blood test and must be kept under constant control. When plasma cholesterol concentrations exceed these levels, it is referred to as hypercholesterolemia. Prevention and treatment of dyslipidemia should therefore be considered as an integral part of individual cardiovascular prevention interventions, which should be addressed primarily to those at higher risk who will benet most. The most commonly used options for the pharmacologic treatment of dyslipidemia are statins, resins, brate, niacin, and their combinations. A PubMed/Medline systematic search was performed using the key phrases management of hypercholesterolemia, guidelines for management of hypercholesterolemia, and pharmacological management of hypercholesterolemia. All the most signicant studies on the pharmacological management of hypercholesterolemia were selected. Statins Statins lower cholesterol levels through three mechanisms linked to each other [10]. Only lovastatin and simvastatin are inactive lattons, which are hydrolysed in vivo into the corresponding active hydroxy acid form [12]. Pharmacy 2018, 6, 10 3 of 16 All statins possess very low systemic bioavailability due to an extensive rst-pass effect. Lovastatin and simvastatin, unlike most statins, are administered as inactive lactone prodrugs [13]. Statins differ mainly in the degree of metabolism and the number of active and inactive metabolites. All statins have active metabolites so that their activity depends also on the prole of both parent compound and active metabolites. Pravastatin has the lowest protein-binding (around 50%) when compared to other statins (>90%); furthermore, statins have a low half-life (14 h), while atorvastatin and rosuvastatin possess the longest terminal half-life (1120 h) [13]. All statins are indicated in cases of primary hypercholesterolemia and mixed dyslipidemia in patients who do not respond to diet, exercise, and other non-pharmacological methods. All statins can be used in cardiovascular prevention as adjuvants to reduce other risk factors with other cardioprotective therapies [15]. Only rosuvastatin should be initiated with a dosage of 510 mg/day, reaching maximum doses of up to 40 mg/day only in patients who have not reached the therapeutic goals established with the lowest doses [11]. In the case of homozygous familial hypercholesterolemia, the recommended dose is 40 mg/day in the evening. In the case of cardiovascular prevention, the usual dose ranges from 20 to 40 mg/day administered in single dose at night, while for atorvastatin, a dose of 10 mg/day is used, although it may be increased as needed [15]. However, we have to mention that important pharmacokinetic interactions can affect the activity/toxicity of statins [16]. The combination of statins with fusidic acid, brates, niacin, or cyclosporine may cause a greater risk of severe myopathy or rhabdomyolysis. The interaction between spironolactones and statins can lead to additive effects of decreasing concentration and activity of endogenous steroid hormones. Cimetidine, ranitidine, and omeprazole may increase blood levels of uvastatin, while rifampicin causes more rapid elimination [17]. The anticoagulant activity of warfarin may increase if administered with uvastatin, lovastatin, rosuvastatin, or simvastatin [17]. Cholesterol and triglyceride metabolism, and molecular mechanisms of lipid-lowering Figure 1. Cholesterol and triglyceride metabolism, and molecular mechanisms of lipid-lowering drugs [12,18]. The recommended dose for adults of Bezafibrate is 200 mg three times a day, or 400 mg of the recommended dose for adults of Bezabrate is 200 mg three times a day, or 400 mg of modified release tablet a day at the main meals [21].

Nahum and I pored over the records of these 21 patients culling out demographic information topical antibiotics for acne vulgaris best 200mg viramune, bed placement p11-002 - antibioticantimycotic solution cheap viramune 200 mg, exposure to virus bulletin purchase discount viramune line medications (particularly injectables) antibiotics for uti elderly buy 200 mg viramune otc, medical examinations patients had undergone antibiotic resistance exam questions order viramune 200mg on-line, and presence of indwelling intravenous devices antibiotics youtube discount viramune 200mg. There was only one significant finding; although cases and controls were equally likely to have intravenous devices in place during their hospital stay, the five case patients were more likely to have a heparin lock in place. In fact, from April 26 to May 2, all five cases had had this device at some point compared with only 5 of 21 of susceptible controls (24%) (P = 0. I knew a few basic things about heparin locks from my internal medicine residency. A heparin lock is a small tube connected to a catheter that is maintained in a vein to allow convenient venous access. I was ignorant, however, about how heparin locks were maintained and went back to the ward the next day eager to follow up on this lead. I was careful to begin with some questions about other, unrelated procedures on the ward. Eventually, I asked the critical question, Could you tell me about the insertion and maintenance of heparin locks on the unit The only difference between the maintenance of an intravenous line and a heparin lock was that the barrel of the heparin lock tube was flushed at regular intervals using heparin solution. This is done so that the blood in the heparin lock barrel will not clot off and eliminate access to the vein. I probed further and asked whether the heparin flush solution came directly from the pharmacy. The nurse stated that no, in general, the heparin solution was prepared on the unit once a day, usually just after the morning change of shifts. Trying to sound offhand, I asked whether each patient had his or her own designated heparin flush solution vial or whether one vial served as the flush solution for all patients on the ward who needed heparin lock maintenance. She stated that the heparin flush solution was kept at the nurses station and that nurses would draw up solution as they needed it. I asked whether the same syringe was used to flush multiple heparin locks and received a shocked look. A new, prepackaged, sterile syringe is used to draw up heparin flush solution, and the same syringe is never inserted into the heparin lock of different patients. The April 26 to May 2nd interval that we were scrutinizing coincided with Passover, an important Jewish holiday. As a result, ward A staffing was minimal, much as it would have been during the Christmas Holidays in the United States. If one of the hepatitis B carriers housed on ward A had a heparin lock in place during this interval, an overburdened staff member might have reused a syringe that had been contaminated while flushing that carriers heparin lock. By readvancing it into the multidose heparin/saline flush solution, the solution itself would have been contaminated. Adding to the plausibility of this mechanism was the fact that additional medical record reviews revealed that of the four hepatitis B carriers on medicine A in late April and early May, only one was in the hospital on April 29, the day when all five cluster patients had been on the unit on the same day. This carrier individual had a heparin lock in place from April 23 through the morning of May 1. Although there was no way to definitively prove it, I had a highly plausible explanation for the first cluster. This explanation was biologically plausible, consistent with available data, and credible given the tendency for error when staff are rushed or overburdened. With some excitement, I called my supervisor, Steve Hadler, and he agreed that I had identified the probable cause of the outbreak but suggested one additional analysis to bolster my case. He speculated that the kind of mistake I was hypothesizing would probably be a one-time event because it represented a gross breach of standard practice. Steve therefore suggested that I examine the association between heparin lock placement on each day of the April 26 to May 2 interval (Table 9-1). Of special interest were the data from April 29th, the only day when all five cluster patients were on the unit. On this date, the Table 9-1 Percentage of Cases and Susceptible Controls With InDwelling Heparin-Lock Placement on Medicine A on Consecutive Days in late April and Early May Date 4/26 4/27 4/28 4/29 4/30 5/1 5/2 % Cases (n) 75 (4) 100 (4) 100 (4) 80 (5) 67 (3) 100 (3) 100 (3) % Controls (n) 11 (9) 36 (11) 9 (11) 0 (9) 11 (9) 11 (9) 14 (14) P (Fishers exact). Specifically, four of five cases had a heparin lock on that day compared to none of nine controls. How could I explain the one patient who did not have a heparin lock in place on the 29th I carefully reviewed the medical record again and found that he was admitted to medicine A from the coronary care unit on the 29th on continuous intravenous therapy. From my own experience as a resident, I knew that when a patient is transferred from one unit to another the patient is jostled and transferred from bed to stretcher and that transient interruptions in intravenous fluid administration may frequently occur. It was possible that while being transported, this case patients intravenous line clotted off. If so, a staff person on ward A may have flushed the line with the contaminated heparin normal saline solution soon after the patient arrived on ward A. This would be done to salvage the line and avoid the need to reinsert an intravenous line at a different site. Statistically, significant associations are demonstrated on other calendar days in the April 26 through May 2 interval, but no other date included all five case patients. Furthermore, it did not surprise me that other days would show an association; a patient who requires a heparin lock on any given day is likely to continue to require it on ensuing days. Although I remained busy during the following days, it mainly amounted to tying up loose ends. Death certificates from those 18 medicine A patients who had died after their April/May admission did not reveal any hint of a liver-related cause of death. Furthermore, the hepatitis B serologic testing performed on patients who had been co-residents of the patients who died of fulminant hepatitis in the June cluster on ward A revealed no other patients with evidence of acute hepatitis B. Thus, the sixth case that had occurred in August was an isolated event, not part of a second cluster, and in fact, he did not have a heparin lock in place. He did, however, undergo a bone marrow biopsy during his stay, had a permanent cystostomy in place, and had an indwelling intravenous line for much of his stay. Three of the dying June cluster patients were present on the ward during his admission. All of these patients had marked coagulopathies, and one was noted to have ongoing blood oozing from his intravenous line insertion site. We hypothesized that the sixth case may have acquired hepatitis B through cross-contamination with blood derived from the June cluster hepatitis patients. After completing the basic investigation, it was time to brief the staff of the Rambam Hospital on my findings and to make recommendations. In that presentation, I reviewed my findings carefully, not only summarizing my positive findings but refuting other potential mechanisms. Further strengthening the case for a common-source, multidose exposure was the tight temporal clustering of the cases and the short incubation periods. The short incubation period favored a high inoculum exposure like that which might result from the direct injection of a contaminated injectable, rather than that which would result if small amounts of infected materials were splashed or rubbed onto an intravenous site. After completing my presentation, I was taken aback when the chief of staff raised his hand and said that I had left out one important possible explanation for the outbreakintentional sabotage. He was concerned that a disgruntled or criminal employee had obtained hepatitis B contaminated fluid and intentionally injected it into these patients. I thought about this and asked why a saboteur would inoculate only those with a heparin lock when intravenous lines would provide equivalent ease of access to the blood stream of patients. Without hesitation, he stated that heparin locks have a flat rubberized port, whereas intravenous systems have a rounded rubberized section for introducing needles. With the latter, it is easier to poke yourself, which might have deterred a saboteur. I advanced other arguments against the sabotage theory, pointing to the fact that use of potassium chloride or poisons would be a more typical approach, but these were countered by the assertion that they would have raised greater suspicion of foul play. I had acquitted myself well during the investigation and had made a good impression. Before I departed, I was offered a position at the Rambam Hospital and the challenge of developing an infectious disease service there. I seriously considered this offer and even inquired about potential positions for my wife, Judy, who was also a physician. At the end of my stay in Israel, I was told that the outbreak investigation was to be kept strictly confidential. Families of the cases would have to be told first and then the decision about publication would be reassessed. I was disappointed in part because it meant that the work might not be published, which affected me personally, but also because the wider world could not benefit from the findings of our investigation. At the airport, when I was getting ready to board my airplane to return to the United States, I was interviewed by security. With some trepidation, I told them that I had been working on a scientific investigation in Haifa with colleagues at the Rambam Hospital. The security agent must have sensed my unease and continued to probe for increasingly specific details of my investigation. Eventually, I divulged that I had been working on an outbreak at the Rambam Hospital. The security official left me alone for a few minutes, and when she came back, I was told I could leave. A few weeks after my return to the United States, I found out that the story had been leaked to the Israeli media. I still consider those 2 years the most exciting professional experience that Ive ever had. Nonetheless, there have been times that I have wondered about the roads I didnt take. Both of my children have graduated from high school now, and as I finish this chapter, I can hear the call of the muezzin from a nearby Mosque. I am in Jakarta, Indonesia launching the first international investigation I have undertaken since I left Israel 22 year ago.

Ramadan occurs in the ninth month of the Islamic calendar, a lunar calendar, changing dates on the Gregorian calendar each year. In the month of Ramadan, Muslims fast during the day, eating at night and avoiding salty foods. There are exceptions to the requirement of fasting, including for those who are menstruating, pregnant, postpartum, traveling, ill, or in battlean important point because the Gulf War had only recently ended and coalition troops were still present in the region. In 1991, the Egyptian Holiday Sham-el-Nessim fell on April 8, coincidental with Ramadan. Sham-el-Nessim is an annual springtime holiday; it is nonsectarian and is celebrated by Islamic and Coptic Egyptian citizens. It is a public holiday occurring annually on Monday, the day after the Coptic Easter Sunday. He had received a call from a doctor in his state who was Egyptian and had relatives in Cairo. She told him there were three adults with botulism intoxication in a hospital in Cairo, all on ventilators, and wanted to know how to obtain antitoxin. After consultation with others in the branch, I recommended that this physician contact companies in Europe that produce antitoxin, as shipment from there would be faster. He said there were hundreds of Cairo citizens crowding the gates of the embassy and pleading for antitoxin. It was front-page news in the Egyptian newspapers, and the Minister of Health was being called into Parliament to explain what had happened and what was being done. This was the first time botulism had ever been reported in Egypt, and it sounded much larger than a typical botulism outbreak. Antitoxin was ultimately obtained from several European companies and the United States Armed Services. Ban Mishu, the preventive medicine resident in the branch, and I were invited to Cairo to investigate the outbreak. Agency for International Development paid for it at the request of their office in Cairo. Second, preventive measures may be taken on the basis of the report of a single case of botulism (Exhibit 10-1). This single case may be a sentinel for a larger outbreak, requiring an investigation to prevent further cases from occurring. Such an investigation is usually carried out by the state or local health department. Food and Drug Administration is notified of each possible case so that suspect foods may be seized and have their production investigated. Without preservation of the cold chain, the antitoxin, scarce and expensive, can be rendered ineffective.

Ideal dosage is unclear but animal studies suggest that increasing the glutamine conAnti-diarrhoeal agents tent of feeds to 25% total amino acids may enhance Loperamide and codeine can be used to slow tranadaptation [56]. Luminal nutrients are the single most important stimulus for adaptation so maximising the time Short bowel syndrome in older children during which nutrients are in contact with the intestine will optimise the potential for adaptation. Intestinal adaptation begins 2448 hours after resection but can continue for up to 3 years. Feeds need to be age appropriate and Continuous feeding allows for maximum nutrient always given at the maximum level of tolerance. Oral feeding will also stimulate gallbladder contraction and gastrointestinal secretions and perhaps therefore contribute Weaning from parenteral nutrition to a reduced risk of intestinal failure associated liver disease.
