Unfortunately the fresh? nature of minimally processed fruits and vegetables prevents the use of traditional processing such as cooking/heating, and consumers are demanding that our foods contain no chemical preservatives. Thus, application of biocontrol concepts may be useful to create extra preservation hurdles for fresh-cut products. Antagonistic organisms to control growth of either spoilage or pathogenic species (biopreservation) 2. Francis and O?Beirne (1998) found that mixed populations of bacteria isolated from shredded lettuce generally diminished the growth of Listeria innocua, when mixed in model media, and they concluded that species of Enterobacter competed with the Listeria species. Pseudomonads also produce antifungal compounds [chitinase and laminarinase enzymes (Lim et al. This will only be possible after complete investigation of the microbial ecology of the system. Microorganisms such as lactic acid bacteria are used as biopreservative agents in foods to inhibit the growth of other undesirable species. Mechanisms of antago nism include competition for nutrients, binding of nutrients and production of met abolic products with antimicrobial activity. In recent years, lactic acid bacteria have also been used as competitive biocontrol agents and antagonists in nonfermented foods (Breidt and Fleming, 1997). Lactic acid bacteria are known to produce antimicrobial metabolites such as lactic and acetic acids, hydrogen peroxide and enzymes including lysozyme. These are described as groups of potent antimicrobial peptides or proteins that are active against other microorganisms (Holzapfel et al. Several studies have described the use of bacteriocin-producing lactic acid bacteria to improve the safety of ready-to-eat salads. Strains of lactic acid bacteria selected for their ability to grow and produce antimicrobial compounds at refrigeration temperatures inhibited the mesophilic? Psychrotrophic strains of Lactobacillus casei, Lactobacillus plantarum and Pediococcus spp. Choi and Beuchat (1994) used a bacteriocin from Pediococcus acidilactici M to inhibit the growth of L. Addition of crude bacteriocin powder (10 mg bacteriocin/150 g salad) was initially lethal to L. Plantaricin D was found to exhibit antilisterial activity, and the authors suggested use of the compound or the biopreservative culture to improve the safety of ready-to-eat vegetables. The commercially available bacteriocin, nisin (from Lactobacillus lactis), has been used in foods such as pasteurized cheese spreads to inhibit outgrowth of Clostridia spores, and it is approved in a number of European countries for addition to fresh cheese, processed vegetables and canned foods (Holzapfel et al. At 12?C (abuse temperature), addition of bacteriocins was necessary to prevent growth of the pathogen. Interest in the use of these compounds is encouraged by consumer demands for natural foods. To date, interest in application of volatiles to fresh produce has focused on treatment of fruits to inhibit the growth of postharvest decay fungi. Ten compounds including hexanal, 1-hexanol, methyl salicylate and methyl benzoate, prevented the growth of Botrytis on blackberries, strawberries and grapes. Volatiles from stone fruit origin including benzaldehyde (5000?10,000 ppm) and hexanal (2500 ppm) were shown by Caccioni et al. Application of natural plant volatiles to fresh-cut salads to improve quality and safety has been investigated by Dawson et al. In this study, a number of volatile compounds (acetic acid, ethanol and several pyruvates) were added to fresh cut, mixed lettuce and cabbage to control the growth of pathogens such as L. Acetic acid and the pyruvates reduced the total count of these vegetables by up to 2 log cycles, and populations of the pathogens were also reduced. Disadvantages of fumigation with volatiles include tainting effects resulting from compounds such as acetic acid, corrosive effects and toxic effects. Nonvolatile compounds such as essential oils may also be used to inhibit spoilage? Plant defense mechanisms and methods to induce resistance were recently reviewed by Forbes-Smith (1999). To date, there are no published reports examining induced resistance and fresh-cut fruits and vegetables. The following section aims to introduce the concepts of plant defense mechanisms and induced resistance. Lignin is a polymeric polyphenol that combines with cellulose and pectin in the plant cell wall to increase resistance to pathogen penetration (Forbes-Smith, 1999). Phytoalexins or phenolic antibiotics? are also produced as a response to infection by microbial plant pathogens. Synthesis of Pathogenesis-Related Proteins Some plant tissues produce antifungal proteins in response to invasion by microor ganisms or as a response to exposure to ethylene (Schlumbaum et al. For example, plant cells produce the lytic enzymes chitinase and chitosinase to degrade fungal cell walls (Baldwin et al. Induced Resistance It is possible to treat plant tissues with substances to elicit the natural defense mecha nisms. Compounds such as methyl salicylate and chitosan are known to be antifungal and have been used to elicit resistance in fruits, including strawberries (Forbes-Smith, 1999). Application of induced resistance methods to fresh-cut produce should be considered as an alternative biocontrol hurdle, as the cutting processes involved in fresh-cut processing may induce an elicitor response. Areas for future research include the effectiveness of elicitors in this environment and the effects of treatment on the sensory quality of fresh-cut products. Optimization of processes to ensure freshness and safety and the application of innovative biocontrol techniques will rely on fundamental investigation of the growth, interactions and biochemical activity of associated microbial species and the mechanisms underlying their development.

A preliminary report to the national advisory committee on microbiologic criteria for foods. The mechanism of the antibacterial action of glycinol, a pterocarpan phytoalexin synthesized by soybeans. Microorganisms on plant surfaces are also commonly associated with, or are contaminants from, soils, insects, mammals, and other animals (Jay, 1997). With the exception of plant pathogens, most microorganisms are gener ally prevented from penetrating produce tissue by outer protective layers such as the epidermis. Plant pathogenic microorganisms can directly attack plant tissues and destroy the whole plant or plant parts. Cutting destroys the internal cell compartment and creates wounds on the plant organs. The wounded tissue releases plant juice or cell contents that serve as nutrients for microorganisms. Thus, cut surfaces, in most cases, are ideal for the growth of microorganisms, including human pathogens. Once in contact with plant, microorganisms are subjected to various levels of microbial-plant interactions or interrelationships for their population expansion. At the low end, plants only provide a physical space or nutrients for microorganisms. The interaction depends on the nature of the microorganisms, the host plant condition and the occurrence of favorable environmental factors. A response to these parameters could involve the coordination expression of the microbial genes. With facultative plant pathogens, the interaction switches between the saprophytic and the pathogenic phases. To participate in the microbe-plant interaction and explore the food sources, microor ganisms may secrete enzymes, toxins, growth regulators and polysaccharides (Agrios, 1997), and the host plants may react to these substances accordingly. Cell cytoplasm contains nutrients that are readily used by microorganisms (such as simple sugars and amino acids) and carbon and energy reserves (such as starches, proteins and fats). The undisrupted surface of a fruit or vegetable is covered with a protective layer called cuticle consisting of cutins.

Surgery should be avoided before 6 months (unless a source of sepsis cannot be drained otherwise), in order to allow the peritoneal cavity to be re-established. It is important to remember that prolonged periods of illness and hospitalisation require psy chological support of both the patient and their relatives. Also, throughout the process, advice and assistance can be obtained from regional centres that specialise in intestinal failure. Some surgeons place a temporary bar under neath this to support it while it heals. The bowel should sit snugly but not tightly within the tract and should be free from ten sion. Sometimes this may be treated conservatively, but it may require resiting of the stoma. This requires reoperation, resection of the affected seg ment and creation of a new stoma. Parastomal hernia: predisposing factors include obesity, increased intra-abdominal pressure and a wide opening in the fascia. These are mostly asymptomatic, but they can interfere with appli ances and can strangulate. Predisposing factors are as for parastomal her nias and also include excessive mobility of the bowel or the presence of a redundant loop. Treat ment includes excision of the redundant portion if the stoma is permanent, or reversal of the stoma if it is temporary. Loop transverse colostomies are best avoided as they are notorious for this problem (consider a loop ileostomy instead). Usually this is asympto matic, but it may cause discharge of blood and mucus per rectum. The cause is considered to be due to lack of contact of the mucosa with short-chain fatty acids. Despite this, malnutrition is much more common in surgical patients than has previously been appreciated, even though its relevance to outcome is well established. Con temporary estimates suggest that up to 39 per cent of surgical patients are malnourished. Although many cases are due to the nature of the disease process itself, many are down to inad equate consideration of, and delivery of, nutrition. Detrimental effects of malnutrition include increased infectious morbidity, impaired immunological function, prolonged ventilator depend ence, decreased wound healing, prolonged hospital stay and increased mortality. It is therefore necessary to have the necessary tools to diagnose, assess and intervene in cases of malnutrition. Impairment of wound healing: can increase the likelihood of surgical wound dehiscence, anasto motic breakdown,? Water and electrolyte disturbances: retention of whole-body sodium and water, with peripheral and pulmonary oedema. There is also depletion in whole-body potassium, magnesium and phosphate, which are essential for protein synthesis. Impairment of psychosocial function: malnutrition results in apathy, depression and self-neglect? An isolated biochemical marker such as serum albumin is not useful, as this is a negative acute-phase protein and normally reduces with surgical stress. Changes in weight in the intensive care setting are largely due to changes in total body water and so do not re? Enteral feeding is the preferred choice whenever possible, using either oral supplements or formulated enteral feeds via feeding tubes. In patients with a non-functioning or inaccessible gut, who need parenteral nutrition, every attempt needs to be made to move on to enteral feeding as soon as possible. Enteral feeding is associated with fewer septic complications, a reduction in gut mucosal atrophy with an improvement of gut barrier function through the direct contact of nutrients (in particular, glutamine), and a lower risk of hepatic steatosis. Enteral feeding Indications and contraindications for enteral feeding See Table 10. Access for enteral tube feeding the choice depends on the expected period of feeding, the clinical condition and the anatomy: ? Nasogastric tubes: easily passed on the ward for short-term feeding of patients with functioning gut but poor appetite and reduced ability to maintain oral intake. Surgically inserted gastrostomies are reserved for patients in whom endoscopic or radiological placement has failed or is not possible. Parenteral nutrition Parenteral nutrition refers to the administration of nutrients by the intravenous route. It is administered via a dedicated central or peripheral line and is used where there is a failure of gut function and the consequent intestinal failure has persisted for and is likely to do so for 5 days. Parenteral nutrition is invasive, expensive and associated with multiple potential complica tions. Normal intravenous nutri tion solutions are not tolerated well by peripheral veins, resulting in early thrombophlebitis. Internal jugular venous access has a lower risk of pneumothorax than subclavian access but is less suited to ambulatory patients. If this is not practical, one lumen of a multi-lumen catheter should be devoted solely to feeding. An excessive dependence on glucose as the energy source in critically ill patients can result in poor utilization due to insulin resistance. Therefore in the criti cally ill patient more than 50 per cent of energy needs should be from lipids. During periods of starvation it is muscle that provides the main labile pool of amino acid pre cursors for hepatic gluconeogenesis to meet cerebral energy requirements (about 100 g of glu cose per day). For each gram of nitrogen that is excreted as a result of amino acid oxidation, 6. It is a cofactor in more than 10 enzymes involved in protein and nucleic acid synthesis, and is required for tissue healing and immune function. It is absorbed from the duodenum and transported in the circulation bound to low and very low-density lipoproteins.

The panel was of interest with development group activity, by written instructed to answer questions and develop evidence disclosure. Disclosures reflected all current and planned pertaining to important aspects of spinal interventional commercial services, including services from which a techniques. Members of the panel were also requested clinician derives a substantial portion of income, non to develop comprehensive systematic reviews on various commercial, intellectual, institutional, and patient/ related subjects in preparation for spinal interventional public activities pertinent to the potential scope of the techniques guidelines (9-32,82-84). The majority of the participants reviews have the potential to improve the decisions attended multiple meetings. The committee Evidence assessment for systematic reviews was formulized the elements of the guideline preparation based on methodological quality assessment criteria process, including literature searches, literature synthe recommended for randomized trials, observational sis, consensus evaluation, open forum presentations, studies, and diagnostic studies (336-356). However, there were no patients, review process derived from evidence-based system patient advocates, or patient/consumer organizations atic reviews and meta-analyses of randomized trials, represented in the guideline development process, observational studies, and diagnostic accuracy studies which may be considered as a deficiency. Overall, good to fair evidence is logic quality or validity assessment were performed. Even though none of these instruments or sures were taken to avoid any conflicting opinions from criteria has been systematically assessed and the advan authors receiving funding from the industry. Patients ex the predetermined minimum number of studies was pect that their doctors and other health care providers available, and finally, analysis of evidence was based know what type of treatment to recommend. The analysis was conducted using 3 systematic reviews of the evidence are objective, trans levels of evidence, ranging from good, fair, and limited parent, and scientifically valid. Consequently, the high prevalence the theoretical basis of controlled diagnostic of chronic spinal pain, the numerous modalities of blocks is that if a patient genuinely has pain from a treatments applied in management of the problem, particular target structure, complete or near complete and the growing social and economic costs continue relief of that pain should be obtained consistently to influence medical decision-making. Despite its whenever that structure is anesthetized, and repeat commonality, both in primary care and tertiary care, ing the diagnostic block can increase the diagnostic it is often difficult to reach a definite diagnosis of accuracy by testing for consistency of response and the origin of spinal pain. If a particular structure is said to source of exponential growth in treatment modali be the target, it must be shown that the structure is ties is the inherent difficulty in obtaining an accurate anesthetized and either does or does not produce a diagnosis. In the search of a diagnosis, an inaccurate result within the distribution of that structure. Face or incorrect diagnosis, may lead not only to expen validity can be tested and established either by a study sive diagnostic ventures, but to treatment failures whose results can be replicated or by testing for face resulting in wasted health care dollars, and diver validity in each and every case. Fundamental be established by radiographic imaging with injection to proper treatment is an accurate diagnosis which of a contrast agent or by a physiological approach uti is based on the reliability of the test used to make lizing a detectable and testable function other than the diagnosis. Construct validity ventional techniques or interventional techniques measures if the test actually works or not, and how (415-422). For diagnostic interventional techniques, there is no conventional criterion standard, such as imaging 1. Thus, and nerve conduction studies in non-radicular pain, a Bogduk (383) has developed testing for construct precise cause of pain may be identified in only approxi validity of diagnostic blocks by other means. However, it such as the false-positive rates can be estimated by has been described that with application of controlled determining how often a diagnostic block is positive diagnostic interventional techniques, a diagnosis may in patients who should not, or demonstrably do not, become a reality in 85% of the patients rather than have the condition in question. Under these conditions, a true-positive Low back pain is the most common of all spinal, response would be the one in which the patient and even chronic, pain problems. Lumbar intervertebral obtained relief on each occasion that an active agent discs, facet joints, sacroiliac joints, ligaments, fascia, was used, but no relief when the inactive agent was muscles, and nerve root dura have been shown to be used. The blocks are performed on separate oc agnosed with physical examination, radiological assess casions using local anesthetic agents with different ment, and neurophysiological assessment (368,374,552 durations of action (383,384,415-422). For chronic low back pain without disc herniation proach, the consistency of response and the duration or radiculitis, the precision diagnostic blocks applied of response are tested. Failure to respond to the include lumbar facet joint nerve blocks, lumbar provo second block constitutes inconsistency, and indicates cation discography, and sacroiliac joint blocks, and to that the first response was false-positive. A response a lesser extent, lumbosacral selective nerve root blocks concordant with the expected duration of action of or transforaminal epidural injections in the diagnosis of the agent used strongly suggests a genuine, physi difficult radicular pain syndromes (11,17,33,36,374). Low back pain is treated based on diagnosis with various modalities including epidural injections, per 2. Facet joint interventions and sacroiliac ity of spinal pain problems and ability of diagnostic joint interventions are utilized in managing facet joint blocks to identify sources of chronic spinal pain. Removal or correction of structural abnormalities of the spine may fail to cure Chronic, persistent low back, lower extremity pain, and may even worsen painful spinal conditions (3,8 and radicular pain may be secondary to disc herniation, 38,82,139,177,195,196,202,207,232,260,261,295,367 disc disruption, disc degeneration, spinal stenosis, or 374,505-551). The degenerative processes of the spine post lumbar surgery syndrome resulting in disc-related and the origin of spinal pain are complex without cor pain with or without radiculitis. Herniated lumbar disc relation of radiographic changes to the clinical picture is a displacement of disc material (nucleus pulposus or and prognosis (8,413-504). The effectiveness of a large annulus fibrosis) beyond the intervertebral disc space. Finally there is increasing evidence supporting numerous treatment modalities for herniated disc pain, the use of spinal interventional techniques in managing following the description of disc herniation by Mixter chronic spinal pain (4-38). The are epidural injections including adhesiolysis, facet prevalence of a symptomatic herniated lumbar disc joint interventions, sacroiliac joint interventions, intra is about 1% to 3% (554) with the highest prevalence discal therapies, mechanical disc decompression, and among people aged 30 to 50 years (555), with a male implantable therapies. Lumbar disc displacement may present as in epidural fibrosis, sacroiliac joint pain, disc herniation, ternal disc disruption, disc prolapse, disc protrusion, disc discogenic pain, spinal stenosis, arachnoiditis, and facet extrusion, disc herniation, or simply discogenic pain. The joint pain, along with inappropriate surgery (8,519,522 estimated prevalence of lumbar radiculopathy or sciatica 524,526,612-626). Lumbar radiculopathy sec spine surgery with multiple authors describing a lack of ondary to disc herniation resolves spontaneously in 23% association (614-617), one study found that patients with to 48% of patients, but up to 30% to 70% will still have extensive epidural fibrosis were 3. Further, experimental studies have first described by Wirshow in 1857, the pathophysiology provided electrophysiological evidence of neurologic and the mechanism of pain due to disc herniation remain disturbances caused by peridural scar formation (622). However, the intervertebral disc multitude of other abnormalities including mechanical has been implicated as a source of spinal pain based tethering of nerve roots secondary to epidural fibrosis on decades of pre-clinical, clinical, and epidemiological in the vertebral canal (623,624), disturbances in blood research, though the precise mechanisms still continue flow (625), and expression of proinflammatory cytokines to be debated as the literature evolves (36,374,379 causing irritation of exposed dorsal root ganglion and 381,566-598). Further, based on controlled evaluations, triggering painful responses have been described (626). Further, in a study that paraspinal muscle spasms, tail contracture, pain behav sought to determine the prevalence of discogenic pain iors, tactile allodynia, epidural and perineural scarring, without assessing internal disc disruption, the reported and nerve root adherence to the underlying discs and prevalence rate was 26% (378). Spinal stenosis can be defined as a narrowing of the In any type of disc-related pain, spinal stenosis, or spinal canal, resulting in symptoms and signs caused by radiculitis, radiographic evidence of disc herniation or entrapment and compression of the intraspinal, vascular, spinal stenosis does not accurately diagnose low back or and nervous structures (374,599-603).

Open discectomy and decompression, with or with Symptoms of central spinal stenosis may be related out fusion, are the most common surgical interventions to a neurovascular mechanism such as arterial flow in performed for disc herniation, spinal stenosis, and post cauda equina, venous congestion, and increased epi surgery syndrome. However, absolute indications for sur dural pressure (603-611); nerve root excitation by local gery, even though rare, include altered bladder function inflammation; or direct compression in the central and progressive muscle weakness (629). Thus, spinal stenosis is a multifactorial tion for surgery is to provide for the rapid relief of pain disorder, and clinical presentation can be variable with and to address the possibility of impending disability in or without neurogenic claudication manifested by pain the majority of patients whose recovery is unacceptably in the buttocks or legs when walking, which disappears low. While it appears that surgery provides good pain with sitting or lumbar flexion (603,609,610). In fact, bar spine and it should not be confused with radicular Carragee et al (550) showed poorer surgical outcomes in pain. The cardinal distinctions lie in the quality of pain patients with massive annular defects and in those with and its behavior. Table 1 shows the differences between an intact annulus and no identifiable fragment in a re radicular and somatic pain. Similarly, it was review of diagnostic procedures for neck and low back also shown that with sequestered or extruded lumbar disc pain, showed that a number of factors can be identified herniations, the prognosis was better than with contained which can assist the clinician in identifying sciatica due to disc herniations with single level microdiscectomy (631). However, they were Patients with contained disc herniations, a predominance unable to show any evidence based on history leading to of back pain, and smoking are expected to have poorer a diagnosis not related to radicular pain.
