In Belgium Infection Control Nurses must register postoperative wound infections, sepsis and ventilation associated pneumonia. At the author's hospital, the incidence of pressure sores is scored four times a year and there is a register of new patients with M.R.S.A. (methicillin resistant staphylococcus aureus) and tuberculosis. Procedures for hospital hygiene can be consulted in order to see which patients must be isolated and what kind of precautions must be taken. The microorganisms and diseases are sorted alphabetically and the cause of cross-infection, isolation procedure and duration of isolation are noted. These procedures must be translated to the different departments and individual patients. For instance a patient with M.R.S.A. is strictly isolated in the general hospital, but not in the psychiatric department. As far as the haemodialysis unit is concerned, patients with chronic renal disease are more sensitive to infections. For this reason correct hand hygiene is very important. Hand washing, hand disinfection techniques and the use of gloves must be promoted. A microbiological control of the hands of staff once a year, combined with an educational programme, can motivate staff in a positive way Needle-stick injuries present a serious occupational hazard for health care workers, especially those working in a haemodialysis unit. Information and needleless haemodialysis may reduce the risk of needle-stick injuries and the risk of viral transmission. Can a nurse, at risk of viral contamination and transmission, refuse to treat a patient? Is the use of hats, overshoes, glasses necessary? How many times are these materials changed, etc.? This paper presents the data of 1. years of M.R.S.A. registration at the author's hospital. M.R.S.A. has become a serious problem in many hospitals since the mid 1970s. Strenuous efforts need to be taken to control its spread. Screening of the nose of patients and of staff can be helpful. The carriers can be treated with mupirocin ointment. Body washing with chlorhexidine is preferred. The use of vancomycin and teicoplanin is a decision for the physician.

This review addresses our present-day knowledge on the role of different cellular adhesion molecules, cytokines and glycoproteins for the detection of sepsis-induced injury in the microvasculature of the human lung using immunohistochemistry. Through the induction and modulation of endothelial cell adhesion molecules, such as E-selectin (CD 62E), the vascular endothelium controls leukocyte extravasation into tissue. E-Selectin, not expressed by unstimulated endothelium, is activated by cytokines and initiates neutrophil recruitment in sepsis-induced lung injury. Since E-selectin is strongly expressed in the pulmonary microvasculature in sepsis-associated fatalities, the immunohistochemical detection of an intense expression of E-selectin in lung tissue is a valuable diagnostic tool in the forensic postmortem elucidation of death due to sepsis. VLA-4 (CD49d/CD29) is strongly expressed on intravascular, interstitial and intra-alveolar leukocytes in sepsis-associated fatalities, whereas in non-septic fatalities an irregular weak immunoreactivity can be observed on interstitial leukocytes and no positive immunohistochemical expression can be observed on intravascular or intra-alveolar leukocytes. ICAM-1 (CD54) is strongly expressed on endothelial cells of the pulmonary microvasculature and on pulmonary macrophages and lymphocytes in sepsis-associated fatalities. In contrast, an infrequent weak immunohistochemical reaction for ICAM-1 is found on pulmonary endothelium and on perivascular leukocytes in non-septic fatalities. The up-regulation of both cellular adhesion molecules can be considered as an useful immunohistochemical postmortem marker of sepsis. Lactoferrin (LF) is an iron-binding glycoprotein located in specific (secondary) granules of leukocytes and plays a central role in the host response to infectious stimuli in providing both bacteriostatic and bactericidal protection. There is a statistically significant association between an enhanced expression of LF on pulmonary leukocytes in sepsis-related fatalities in contrast to non-septic controls. The immunohistochemical detection of an enhanced expression of LF can contribute to the postmortem discrimination between sepsis and non-septic fatalities. Application of carbohydrate-specific lectins (ConA, UEA, GSA I, GSA II, MPA, PNA, Jac, WGA, MAA, LPA, SNA) on deparaffinated lung tissue sections from sepsis-associated fatalities and control cases results to some extent in different staining patterns of alveolar epithelial cells and subepithelial seromucous glands of the bronchi. Apart from differences in binding sites for alpha-mannose, N-acetyl-neuraminic acid and alpha-(2-6)-galactose (as detected by different expression for ConA, MAA and SNA), the main finding is that no binding sites for alpha-N-acetyl-galactosamine (as investigated by MPA immunoreactivity) can be detected on alveolar epithelial cells and mucous parts of subepithelial seromucous glands in sepsis cases in contrast to the presence of such binding sites in controls. Since most intracellular pathogens persist in macrophages and epithelial cells during infection, it is likely that these pathogens contribute to a continual deprivation or consumption, respectively, of glycoproteins physiologically secreted by alveolar epithelial and glandular cells at different time points and stages of infection and may, among other mechanisms, by reducing pathogen clearance amplify the inflammatory response. Vascular endothelial growth factor (VEGF), an angiogenic and chemotactic peptide, is abundantly expressed in normal lung tissue, especially in alveolar and bronchial epithelium, glandular cells of the bronchi, and activated alveolar macrophages. Pulmonary VEGF immunostaining differs in sepsis when compared to healthy individuals. In the latter a preponderant strong VEGF immunoreaction can be found on alveolar epithelium (predominately type II pneumocytes), bronchial epithelium and glandular cells of the bronchi and bronchioli, and activated alveolar macrophages. In contrast, in sepsis no VEGF immunopositivity can beivity can be observed on bronchial epithelium or glandular cells of the bronchi and bronchioli, and no or relatively sparse VEGF immunoreactivity is found on alveolar epithelial cells. The precise mechanisms of the decreased pulmonary VEGF expression in septic patients under conditions of intensive care medicine are not clear at present. During the complex cascade of excessive pro-inflammatory and anti-inflammatory mediator release involved in the host's systemic inflammatory response in the development of sepsis-induced lung injury, VEGF expression may be suppressed in sepsis by a hitherto not identified agent or the interaction of different mediators of cellular inflammation. For the detection of sepsis-induced lung injury the aforementioned markers can be used sufficiently, e.g. to give immunohistochemical evidence of a previously undiagnosed sepsis and to confirm or rule out a presumed diagnosis of a sepsis-associated fatality. The employment of the presented immunohistochemical methods will be particularly helpful when macroscopical and routine histological autopsy findings in cases of suspected fatal sepsis are unspecific or unconvincing, respectively, and clinical data on the patient's previous history are not available. Referring to the forensic argumentation regarding causality on the subject of possibly fatal septic complications, e.g. in the sequel of diagnostic or therapeutic iatrogenic injection procedures or being relevant to pressure sore-associated fatalities, aetiopathogenetic conclusions can be optimized on the basis of the described micromorphological investigations.

The treatment of pressure sores in elderly patients requires careful documentation and a comprehensive treatment plan, which takes into account the patient's overall situation. The treatment has to be evidence based. At the moment only three recommendations can be based on two or more prospective, randomized clinical studies: to use a dressing to maintain a moist environment at the wound/dressing interface, to reduce the risk of infection and enhance wound healing by hand washing, wound cleansing and debridement and to institute a systemic antibiotic treatment for patients with advancing cellulitis, sepsis and osteomyelitis. For other treatment options such as topical negative pressure, maggot therapy, electromagnetic therapy, therapeutic ultrasound or growth factors, the data at present are not sufficient to support general use in pressure sore treatment.

Classical familial amyloid polyneuropathy may have a course with progressive renal impairment. We studied 62 patients (24 males, 38 females) with FAP, transthyretin variant V30M, and end-stage renal disease (ESRD) treated with hemodialysis, all referred to a single center over a period of 11 years. Clinical course, morbidity and survival after dialysis were analyzed. Patient's mean age at first dialysis was 51.5 +/- 10.7 years, and mean duration of neuropathy was 10.2 +/- 3.8 years. The most frequent form of presentation of FAP nephropathy was nephrotic proteinuria with renal dysfunction. In the year prior to dialysis, renal function declined rapidly, and fluid overload was the main indication to initiate treatment. The presence of decubitus ulcers, significant disability, venous catheter for definitive vascular access for long-term treatment, and permanent bladder catheter, were related to death during the first year of dialysis. The mean duration of renal replacement therapy was 21 months, with a 54.5% one year, and 38.4% two year treatment survival. However, when the duration of neurological symptoms at first dialysis exceeded 10 years, survival was significantly lower. Infections, (41% were decubitus ulcers with sepsis) were the cause of early, as well as late mortality. Early creation of vascular access for hemodialysis, surveillance of skin wounds, and intervention on neurogenic bladder are essential to improve the prognosis of ESRD in FAP.

Sacral pressure sore treatment requires a multidisciplinary approach, the surgical procedures following nutritional and medical status rehabilitation, spasticity control and sepsis treatment. Serial surgical debridement might also precede flap coverage. Gluteal flaps design such as rotation, transposition or V-Y advancement is selected according to the shape and size of the sore. Our experience with 74 patients with 95 flaps includes 38 rotation flaps, 28 V-Y and 8 transposition flaps. Twenty one patients had bilateral gluteal V-Y flaps. Only 2 transposition flaps had marginal necrosis that healed per secundam. Delayed healing occurred in 12 cases due to sepsis, that healed spontaneously in 10 cases and required surgical reintervention for excision and flap reposition in 2. Prolonged bed immobilization, postoperative antibiotic therapy and late suture removal are important factors in surgical success.

Little is known as to what happens to people with Huntington's disease (HD) at the end of life. Exploratory analysis was performed for all admissions of people with HD in the Nationwide Inpatient Sample database, a 20% stratified sample of all US hospitalizations, from 1996 to 2002. Using the principal diagnosis and procedure, admission cohorts were determined. The common HD-associated reasons for admission were pneumonia (including aspiration, 22%), psychiatric (21.5%), debilitation (hypovolemia, nutritional deficiencies, and decubitus ulcers, 15.5%), trauma (5.7%), and nonpulmonary infections (urinary tract infections and sepsis, 11.%). Twenty-two percent were admitted for medical problems unrelated to HD. Emergency departments were the most frequent source of admission (60%), most had Medicare or Medicaid as the expected payer (80.6%), 54.4% of all admissions were discharged to long-term care facilities (LTCFs), and 3.7% died. The highest mortality was seen in the pneumonia (7.68%) and sepsis (7.39%) cohorts. Of the elective admissions, between 49.71% and 60.31% were discharged to LTCFs, representing new LTCF admissions. Based on this exploratory analysis, hospitalized HD patients are admitted late in the course of their illness, are severely disabled, and are commonly discharged to LTCFs. With 60.31% of the discharges representing new LTCF admissions, this finding shows that there is no going home from the hospital for people with HD.

A 51-year-old man with poliomyelitis was admitted to emergency because of a severe decubitus ulcer on his right hip that was associated with infection. His general condition deteriorated and he was malnourished and dehydrated. Despite adequate hyperalimentation and antibiotic administration, laboratory data indicated pancytopenia 4 days later. He was diagnosed as having secondary hemophagocytosis (HPS) associated with methicillin-sensitive Staphylococcus aureus sepsis due to decubitus inflammation based on bone marrow aspiration and a blood culture. Although granulocyte colony stimulating factor, packed red blood cell transfusions, platelet transfusions, and antibiotics gradually improved the pancytopenia, the patient died of massive gastrointestinal tract bleeding.

This study estimates that Medicare extra payments under the hospital prospective payment system (PPS) range from about $700 per case of decubitus ulcer to $9,000 per case of postoperative sepsis in the five types of adverse events identifiable in Medicare claims. Medicare extra payment for the five types of events totals more than $300 million per year, accounting for 0.27 percent of annual Medicare hospital spending. But these extra payments cover less than a third of the extra costs incurred by hospitals in treating these adverse events. We conclude that both Medicare and hospitals gain financially by improving patient safety.

Elder neglect, one of the 6 forms of elder maltreatment, is difficult to diagnose and is underreported both in the scientific literature and to law enforcement. Recognizing fatal neglect is even more challenging especially with concurrent organic disease. Many entities can mimic elder neglect, and many age-related changes can result in pathology that may be confused with maltreatment. We retrospectively reviewed all forensic cases of individuals age sixty-five years and older which were referred for autopsy. Cases of fatal neglect were analyzed as to age, sex, race, cause of death, location of incident, perpetrator, victim-to-perpetrator relationship, and autopsy and ancillary findings. The cases studies totaled 8. The age range was 74 to 94 years. Two were white, 6 black, one male, and 7 female. The causes of death were sepsis due to severe decubitus ulcers and severe dehydration. Five cases occurred in the victim's home, and 3 occurred in an institution (nursing home/care facility). In 5 cases, the perpetrators were family members. The pathophysiology of aging with respect to elder maltreatment is reviewed.

This article presents an overview of nutritional, herbal, and homeopathic treatment options from complementary and alternative medicine (CAM) as adjuncts in stroke prevention, treatment, and rehabilitation. Despite many promising leads, the evidence does not favor recommendation of most of these treatments from a public health policy perspective. However, simple preventive interventions such as use of a high-quality multivitamin/multimineral supplement in patients with undernutrition may improve outcomes with minimal long-term risk. Natural agents such as the antioxidant alphalipoic acid, certain traditional Asian herbal mixtures, and some homeopathically prepared remedies show promise for reducing infarct size and associated impairments. A number of nutrients and herbs may assist in treatment of stroke-related complications such as pressure sores, urinary tract infections, and pneumonia. Individualized homeopathy may even play a helpful adjunctive role in treatment of sepsis. However, a great deal of systematic research effort lies ahead before most of the options discussed would meet mainstream medical standards for introduction into routine treatment regimens.
