The major benefits will occur in individuals at high risk and in developing countries like India. Financial assistance for drugs including erythropoietin has also been kept separately. Improving the standard of dialysis and auditing its delivery system to patients 10. Training dialysis physician and dialysis technician through a structured programme. To undertake activities related to policy/programme correction as & when required. Develop a manpower training program for dialysis physician and dialysis technician 6. There are mainly two aspects (i) increasing the opportunities for training programs for different categories and (ii) training the existing personnel for skill in the area of dialysis. New Dialysis units established and older ones strengthened (At least some centers in each metro) th 4. While former will need lifestyle modification, behavioral changes, improved information campaign etc. Deceased Organ Retrieval as well as living donors’ promotion is going to be main area for improving supply. More transplant centre, dialysis centre, transplant surgeons and nurse will build up the capacity of improved services. Free or subsidized diagnostic services & immunosuppressive drug supply will ensure better outcome of transplant services. India is also taking steps towards managing its population burden of diseases contributing to end- stage organ failure. Despite limited budgetary support for public health, several comprehensive prevention initiatives have been implemented. Inter-sectoral health promotion efforts will also contribute to decreasing the burden of these diseases. Prototype of Dialysis (stand alone) centre Advisory group meetings were held to develop prototype for standalone dialysis centers. The aim is to provide long term high quality hemodialysis facility for general public (& Govt. In this business model, Government does not make an outright purchase of capital equipment for a dialysis clinic and instead, Government enters into a contractual agreement to lease its capital equipment requirements to private hemodialysis provider company or patient brings his own dialysis disposables. During the contractual period, Government purchases its dialysis consumable requirements exclusively from private partner. There has to be a fixed term of payment to private partner, say every month or say 30 day. The concept is to set up a chain of dialysis centers that would have a non nephrologist dialysis trained physician present at the centre round the clock. A tie up could be made with identified agency for provision of services including equipments, manpower and consumables etc. There would be one standalone dialysis centre operationalised in 100 districts with private public partnership. States would be encouraged to have dialysis facilities through decentralized National Rural Health Mission planning. The average cost of dialysis in Delhi is as follows: Item Cost Average cost of Dialysis 1000 Per dialysis cost for Haemo dialyser ( 600 for 4 time use) 150 Haemodialysis fluid used in each dialysis 200 Saline drip used in each dialysis 100 Inj. Heparin in each dialysis 50 Total cost of Each dialysis 1500 Cost of investigations and medicines 600 Total cost per dialysis including investigations & medicines 2100 121 Till the time dialysis facilities are developed, chronic kidney patients who are below poverty line would be paid for dialysis on per case basis. Reputed large Hospital in the region would be taken on retainership basis and paid per case basis. For this purpose if 1000 dialysis per month are to be supported the expenses would be about Rs. This model would be shifted to private public partnership wherein 1000 dialysis per month per centre would be assured. While former will need lifestyle modification, behavioral changes, improved information campaign and pharmacological interventions etc. Deceased Organ Retrieval is going to be main area for improving supply, although living organ transplant particularly for kidney and to some extent for liver needs to be continued. More dialysis centres and its staff, transplant centre with transplant surgeons and nurses will build up the capacity of improved services. Free or subsidized diagnostic services & immuno-suppressive drug supply for the poor and needy will ensure better compliance and outcome of transplant services. Post-transplant services to transplant recipients and living donors Strategies: • Enhancing the facilities for organ transplantation throughout India • Establishing network for equitable distribution of retrieved deceased organs. Objectives: • To organize a system of organ procurement & distribution for deserving cases for transplantation. Each zonal unit would look after few hospitals in their respective jurisdiction for organ retrieval/transplantation. One new transplant centre would be established and one would be strengthened in Govt. A co-ordination committee could be formed to look into the actions and co-operation required from various ministries and departments. National and regional workshops on issue of organ transplantation would be carried out with purpose of advocacy at all levels for various stakeholders. Certificate of recognition to the donors will be given by the transplant centre on behalf of the appropriate authority. Steps would be taken to make provision for diagnostic tests at affordable and subsidized cost to the transplant recipients and donors patients in the public sector health care delivery system. Free annual health check to living donor & free treatment of all donor related complications would be promoted. Financial assistance for immunosuppressant drugs has also been kept separately which would benefit about 5000 patients every year @ Rs. Establishing 10new facilities for Kidney & 2 new for liver Transplantation in Govt. Strengthening of 10 existing kidney & 2 existing liver transplantation facilities in Govt. Training retrieval team members, transplant surgeon, dialysis physician, nurse, grief counselor, coordinator and dialysis technician through a structured programme. To undertake activities related to policy/programme correction as & when required. To start scheme for promoting/facilitating deceased donation & protecting donors/transplant surgeons.

As it is assumed that peri-implant mucositis is the precursor to peri-implantitis and that a continuum exists from healthy peri-implant mucosa to peri-implant mucositis and to peri-implantitis 5 mg fincar sale prostate on ct, prevention of peri-implant diseases involves the prevention of peri-implant 4 mucositis and the prevention of the conversion from peri-implant mucositis into peri-im- plantitis discount fincar 5 mg fast delivery man health recipe, by timely treatment of existing peri-implant mucositis (Jepsen et al 5 mg fincar overnight delivery androgen hormone used to detect. Preven- 5 tion is based on proper case selection generic fincar 5mg fast delivery mens health vs muscle fitness, proper treatment planning, proper implant placement and properly designed restorations, but also, on regular monitoring of the implants and me- 6 ticulous maintenance by both the dental care professionals and the patients (Tarnow, 2016). Aims of this thesis 7 The removal of bioflm from the surface of an implant-supported restoration, professionally administered and/or self-performed, constitutes a basic element for the prevention and treat- 8 ment of peri-implant diseases. Mechanical instruments and chemical agents are the instruments most commonly 9 used for this purpose. The frst aim of the thesis was to assess the effect of the abovementioned instruments on different titanium dental implant surfaces. The effcacy of various patient-administered, mechanical modalities for plaque removal from implant-supported restorations was also evaluated. A second aim of the thesis was to develop a clinical guideline to aid in decision-making regarding the diagnosis, prevention and treatment of peri-implant diseases. Recommenda- tions regarding the best available instruments to use on dental implant surfaces were also incorporated. In chapter 4, the aim was to systematically evaluate, based on the available evidence, the ef- 5 fect of different mechanical instruments on the biocompatibility of titanium dental implant surfaces. In chapter 5, the aim was to investigate in vitro the possible effect of fve commercially avail- 6 able air-abrasive powders, on the viability and cell density of three types of cells: epithelial cells, gingival fbroblasts and periodontal ligament fbroblasts. Disclaimer: The majority of the chapters in this thesis have already been published in scientifc dental jour- nals. The study design is comparable in various aspects and some text duplications were inevitable. Because most chapters are based on separate scientifc publications, but often concern similar topics, there is inevitably considerable overlap between chapters. Different journal requirements have also created some variations in terminology from one chapter to the next and different reference style.

Introduction 19 20 Chapter 2 / Titanium surface alterations following the use of different mechanical instruments: a systematic review / A. Peri-implant diseases include two entities: peri-implant mu- 2 cositis and peri-implantitis (Zitzmann & Berglundh 2008). According to the consensus report of the 6th European Workshop on Periodontology, peri-implant mucositis is defned as an in- fammatory reaction in the mucosa surrounding a functioning implant while peri-implantitis 3 describes an infammatory process that affects the soft tissues around an osseointegrated implant in function and results in the loss of supporting bone (Lindhe & Meyle 2008). Peri-implant diseases have been associated with predom- 5 inantly Gram-negative anaerobic fora (Mombelli & Lang 1998). Bacterial colonization on oral implant surfaces starts immediately after contact with the oral environment and occurs rapidly (Fürst et al. Within weeks after the placement of implants in the oral cavity, 6 a sub-gingival fora associated with periodontitis is established (van Winkelhoff et al. This colonization seems to be infuenced by the surface roughness, 7 surface-free energy and chemical composition (Quirynen et al. Currently, vari- ous types of implant surfaces, ranging from smooth machined to rough surfaces, are used in different implant components (Esposito et al. Hence, the removal of bacterial bioflm from an implant surface constitutes a basic element for the prevention and treatment of peri-implant diseases (Klinge et al. The instruments used for surface decontamination should not make the surface more bioflm-retentive but they should aim to minimize the de novo formation of bioflm. To our knowledge, there is no direct evidence for the effect of roughness induced by instruments on plaque accumulation. The main problem associated with the removal of plaque from 4 implant surfaces is the possible damage to the implant surfaces. Any damage to the surface induces changes in the chemical oxide layer that may result in increased corrosion. This pro- 5 cess impairs the adhesion of fbroblasts and thus the biocompatibility of the implant (Dmy- tryk et al. These results have led to a demand for plaque and calculus 6 removal only using instruments that cause little to no surface damage. Different treatment modalities and instruments have been suggested for the decontami- nation of implant surfaces, as part of the surgical treatment of peri-implantitis both in ani- 7 mals and in humans, either as stand-alone treatments or in various combinations including mechanical instruments, chemical agents and lasers (Schou et al. All of these methods 8 have been associated with advantages and disadvantages, with no defnitive gold standard. It should be noted, however, that surface decontamination was not the primary parameter evaluated in the abovementioned studies. The effect of different mechanical instruments on titanium surfaces with respect to sur- face changes, cleaning effcacy and cell adherence (biocompatibility) has been evaluated in several in vitro studies (Fox et al. Some of these instruments, such as metal curettes and conventional sonic and ultrasonic scalers, have shown to damage the implant surface severely. Other instruments such as non-metal instruments and air abrasives, although less damaging, have been associated with incomplete removal of plaque and potentially damag- ing products or possible surgical complications, such as emphysema (Schou et al. The surface profle and roughness produced by the different instruments may signifcantly impact the newly formed bioflm, thus playing an important role in peri-implant health maintenance. So far, there is little consensus regarding instruments that are more appropriate for use on implant surfaces. At present, systematic reviews are con- 2 sidered to be the strongest form of medical evidence. They are considered to be the primary tool for summarizing the existing evidence in a reproducible and systematic way, and they are crucial for evidence-based dentistry. To date, no systematic review has evaluated the existing 3 information regarding the infuence of mechanical instruments on implant surfaces. Therefore, the aim of this review is to systematically examine, based on the existing lit- 4 erature, the effects of different mechanical instruments on the characteristics and roughness of implant surfaces. The search was designed to include any published study that evaluated the effects of mechanical instruments on titanium surface characteristics. All possible treatment modalities for the cleaning of titanium surfaces were included, which ensured the inclusion of papers that used mechanical means as an alternative to other treatment modali- ties. All reference lists of the selected studies were hand-searched by the two reviewers (A. The papers’ titles and abstracts were frst screened independent- ly by two reviewers (A. Those papers that fulflled all selection criteria were processed for data extraction.

However, the true mechanisms underlying the effectiveness of acupuncture are still under debating. In this model, acupuncture is believed to treat the diseased organ of the patient by balancing the Yin and Yang conditions that are regulated by an energy substance (Qi) flowing constantly through the whole meridian, a network connecting all the organs of the body. Therefore, in the acupuncture treatment, it is crucial to select special acupoint(s) along the meridian that links the diseased organs, as well as to modulate the Qi flowing in the meridian through the induction of the needling sensation (De-Qi). On the other hand, a neurobiological model established in the recent decades, has supported the notion that an important mechanism of acupuncture in curing diseases is mediated by the nervous system. Stimulation by needles at acupoints is considered to initiate acupuncture signals through the nerve fibers (e. The acupuncture signal is transmitted through the central nervous system, which activates and integrates with the neurons located in broad areas, such as those in the cortex, limbic system, brainstem, spinal cord, which in turn, regulate other systems. The nerve-mediated model provides us a better explanation regarding the biological mechanisms of acupuncture signal transmission in the body which has been broadly documented by both in vivo and in vitro studies under controlled conditions. In this chapter, we will review in particular, the research concerning the influence of acupuncture-elicited signals in the nervous system and how the neural pathways mediate the therapeutic effects of acupuncture. Keywords acupuncture signal, afferent nerves, autonomic nervous system, central nervous system, transmission Acupuncture Therapy of Neurological Diseases: A Neurobiological View 3. Modern clinical research has confirmed the impressive therapeutic effect of acupuncture on numerous human ailments, such as controlling pain, nausea, and vomiting. According to this model, acupuncture is believed to treat the diseased organs by modulating two conditions known as Yin and Yang, which represent all the opposite principles that people find in the universe, both inside and outside the human body. Yin and Yang complement each other, and are subjected to changes between each other. The balance of Yin and Yang is thought to be maintained by Qi, an energy substance flowing constantly through the meridian, a network connecting all the organs of the body. The illness, according to this theory, is the temporary dominance of one principle over the other, owing to the blockade of the Qi from flowing through the meridian under certain circumstance. Thus, the goal of acupuncture treatment is to restore the balance of Yin and Yang conditions in the diseased organ(s). This theory has been considered to be useful to guide this ancient therapy, such as carrying out diagnosis, deciding on the principle, and selecting the acupoints. However, neither Qi nor meridian can be detected under a controlled condition in the animal model or in humans, using current scientific technology. In the past 50 years, extensive efforts have been taken to explore the biological mechanisms and its significance in acupuncture, using modern technologies. The successful results of the tests, ranging from animal experiments to clinical analysis, clearly support the neurobiological hypothesis of acupuncture in regulating multiple systems including the hormonal and immune system. Hypothetically, the acupuncture signal is initiated at the acupoints surrounding the nerve terminals, and is transmitted to the intro- and super-spinal regions, following the afferent nerve fibers. In the central nervous system, the acupuncture signal is believed to regulate the activity of the neurons in certain brain areas (i. Indeed, through controlled experiments, a chain of events triggered by the mechanical stimulation at the acupoints with needling or its electrical equivalent (electro-acupuncture) can be traced. For instance, in the human or animal model, the acupuncture-induced unit discharges of neurons could be recorded using electrophysiological methods, the level of synthesized and/or the release of a neurotransmitter or its receptor can be measured by biochemical assays, and the activity of a brain area owing to acupuncture can be monitored by noninvasive functional imaging methods, thus, investigating the association of acupoint-brain activity. The fact that acupuncture 82 3 Neural Transmission of Acupuncture Signal could activate or inhibit specific brain areas associated with functions of nociceptive, cardiovascular, and vision, suggests that a number of neural circuits and substrates are specifically involved in the therapeutic effect of acupuncture. Among them, the limbic system which mediates both the neural-endocrine system and the brainstem-descending control-spinal cord in the acupuncture analgesia has been perhaps the most extensivelystudied. The diagram shows that one of the mechanisms of acupuncture is regulation of the autonomic nervous activity that modulates the body homeostasis. The acupuncture signal is first transmitted to the central nervous system via the sensory nervous system (including afferent fibers, thalamus, cerebral cortex, etc. However, the biological mechanisms underlying acupuncture are yet to be fully understood. Neither the meridian model nor the neurophysiological model could completely elucidate all the findings obtained from the clinical tests and research, and both the theories have their shortcomings and limitations. In this chapter, we will discuss whether (1) the neural signal initiated by stimulation of acupoint could influence in the activation of numerous neural pathways in the central and peripheral nervous 83 Acupuncture Therapy of Neurological Diseases: A Neurobiological View systems; and (2) the activation changes of those neural pathways underlie the therapeutic effect of acupuncture.

Severe Skin and Soft Tissue Infections in Critical Care 305 Figure 6 Postoperative view in a diabetic patient with necrotizing fasciitis of right leg due to group G Streptococcus. Results are contradictory, with no real epidemiologically based studies performed (for treatment refer to Table 3). It is a fulminant, rapidly progressive subcutaneous infection of the scrotum and penis, which spreads along fascial planes and may extend to the abdominal wall. Fournier gangrene occurs commonly without a predisposing event or after uncomplicated hemor- rhoidectomy. Less commonly this can occur after urological manipulation or as a late complication of deep anorectal suppuration. Fournier gangrene is characterized by necrosis of the skin and soft tissues of the scrotum and/or perineum that is associated with a fulminant, painful, and severely toxic infection (58,59). Successful treatment is again based on early recognization and vigorous surgical debridement. Clostridial Myonecrosis (Gas Gangrene) Clostridium perfringens type A is the most common organism. Although initial growth of the organism occurs within the devitalized anaerobic milieu, acute invasion and destruction of healthy, living tissue rapidly ensues. Historically, clostridial myonecrosis was a disease associated with battle injuries, but 60% of cases now occur after trauma. It is a destructive infectious process of muscle associated with infections of the skin and soft tissue. It is often associated with local crepitus and systemic signs of toxemia, which are formed by anaerobic, gas-forming bacilli of the Clostridium sp. The infection most often occurs after abdominal operations on the gastrointestinal tract; however, penetrating trauma, and frostbite, can expose muscle, fascia, and subcutaneous tissue to these organisms. Common to all these conditions is an environment containing tissue necrosis, low-oxygen tension, and sufficient nutrients (amino acids and calcium) to allow germination of clostridial spores. Clostridia are gram-positive, spore-forming, obligate anaerobes that are widely found in soil contaminated with animal excreta. They may be isolated from the human gastrointestinal tract and from the skin in the perineal area. This organism produces collagenases and proteases that cause widespread tissue destruction, as well as a-toxin, which have a role in the high mortality associated with myonecrosis. The a-toxin causes extensive capillary destruction and hemolysis, leading to necrosis of the muscle and overlying fascia, skin, and subcutaneous tissues. Patients complain of sudden onset of pain at the site of trauma or surgical wounds, which rapidly increases in severity. Examination of the wound discharge reveals abundant large, boxcar-shaped gram-positive rods with a paucity of surrounding leukocytes. The usual incubation period between injury and the onset of clostridial myonecrosis is two to three days, but may be as short as six hours. A definitive diagnosis is based on the appearance of the muscle on direct visualization by surgical exposure. As the disease process continues, the muscle becomes frankly gangrenous, black, and extremely friable. Serum creatinine phosphokinase levels are always elevated with muscle involvement. Among the signs that predict a poor outcome are leukopenia, thrombocytopenia, hemolysis, and severe renal failure. Myoglobinuria is common and can contribute significantly to worsening of renal function. Frank hemorrhage may be present and is a harbinger of disseminated intravascular coagulation. Successful treatment of this life-threatening infection depends on early recogni- tion and debridement of all devitalized and infected tissues. The role of hyperbaric oxygen therapy has not been established (100% oxygen at 3 atm), but it may have a role early in the treatment of seriously ill patients (19,20). The mainstay of treatment is surgical debridement, and this should not be delayed. In this process, the bacterial tissue invasion is primarily superficial to the fascial layer, without muscle involvement. Prompt recognition and treatment, as described earlier, can reduce the associated morbidity and mortality. Protein synthesis inhibitors such as clindamycin when combined with penicillin has had considerable better efficacy than penicillin alone. Anaerobic streptococcal myonecrosis clinically resembles subacute clostridial gas gangrene. The involved muscles are discolored, in contrast to gas gangrene, early cutaneous erythema is prominent. The infection is usually mixed; anaerobic streptococci with group A Streptococcus or S. Treatment involves the use of high-dose penicillin and antistaphylococcal agent, if indicated, and surgical debridement. Cellulitis often develops within 12 to 24 hours, accompanied by excruciating pain, marked edema, and bullae. Infected vascular gangrene is a focal, usually indolent and primarily ischemic process in the small muscles of a distal lower extremity already gangrenous from arterial insufficiency. Diabetic patients are prone to develop this complication, which usually does not extend 308 Sharma and Saravolatz beyond the area of vascular gangrene to involve viable muscle. Bacterial infection of the muscle usually occurs after a penetrating wound, vascular insufficiency, or a contiguous spread. Common muscle involvement includes deltoid, psoas, biceps, gastrocnemius, gluteal, and quadriceps, though any muscle group can be involved. Patients will typically present with fever, pain, tenderness, and swelling of the involved muscle. Early modification of initial antimicrobial therapy is based on Gram stain and culture results. The most common lesion requiring hospitalization is the infected diabetic foot ulcer (Fig. Neuropathy plays a central role, with disturbances of sensory, motor, and autonomic functions leading to ulcerations due to trauma or excessive pressure on a deformed foot. This wound may progress to become actively infected, and by contiguous extension the infection can involve deeper tissues. Various immunological disturbances, especially involving the polymorphonuclear leukocytes, may affect some diabetic patients. Chronic wounds develop a more complex colonizing flora including enterococci; Enterobacteriaceae; obligate anaerobes, P. Therapy Initial therapy is empirical and should be based on severity of infection and available microbiological data, such as recent culture results or current smear findings from adequately obtained specimens. The microbiology can be identified by culture only if specimens are collected and processed properly. Deep tissue specimens, obtained aseptically at surgery, contain the true pathogens more often than do samples obtained from superficial lesions. A curettage or tissue scraping with a scalpel from the base of a debrided ulcer provides more accurate results. An antibiotic regimen should always include an agent active against staphylococci and streptococci.
