    Nosocomial infections are the 11th leading cause of death in the United States, cost approximately $4.65 billion yearly--and can be prevented. Patients are at risk for nosocomial infection, especially when they undergo surgical procedures. It is important to know and carry out the principles of asepsis to reduce this risk of infection regardless of where the procedure occurs.

    This paper examines the origins of aseptic surgery in the German-speaking countries. It interprets asepsis as the outcome of a mutual realignment of surgery and laboratory science. In that process, phenomena of surgical reality were being modelled and simplified in the bacteriological laboratory so that they could be subjected to control by the researcher's hands and eyes. Once control was achieved, it was being extended to surgical practice by recreating the relevant features of the controlled laboratory environment in the surgical work place. This strategy can be seen in the adoption of Robert Koch's bacteriology by German-speaking surgeons, and the resulting technical changes of surgery, leading to a set of beliefs and practices, which eventually came to be called 'asepsis'.

    2004-09-01

    To evaluate hygiene in dental offices in Dakar, the authors questioned 64 public, private and semi-private dentists. From 62 practitioners who completed their questionnaire, it appeared that the dry-heated sterilizer (poupinel) was 5 times more used than the autoclave; The almost practitioners sayed respecting the sterilisation process and 66% of them said wearing gloves, masks and glasses during interventions. In spite of the hope these results give, this study is limited because it doesn't take into account many aspects of asepsis and antisepsis in dental office which require a rigorous application next to a personal who needs to be better trained.

    1996-01-01

    Competence as communication skills and as skilled practice of asepsis were studied by observing four nurses while interacting with patients and performing intravenous procedures. Nurses were observed using sterile equipment for methods of intravenous therapy. Asepsis is performed frequently, but through misunderstanding in the learning of asepsis or improper model learning the nurses may establish incorrect routines. When performing procedures, unexpected factors can distract both the expert and the inexperienced, resulting in a failure to apply basic aseptic techniques. The nurses showed an interest in the patient by listening and giving responses. Nurses may control interactions with the patient by using undesirable communication skills which include incomplete sentences, incomplete explanations and closed questions. Asked to evaluate their own behavior, the nurses did not estimate whether or not the appropriate skills were applied in observed situations. To improve the quality of nursing care performance it is recommended to further develop and apply skill training programs.

    The long saphenous vein may be harvested from the thigh or the lower leg, depending on the operating surgeon's preference. This prospective study compared the incidence of altered wound healing between these two sites in 175 patients undergoing routine coronary artery bypass grafting over a 3-month period. The patients were divided into 3 groups. In group A, the vein harvest site was restricted to above the upper border of the patella. Group B included harvest sites that started at the ankle but extended above the level of the upper border of the patella. In group C, the vein harvest site was restricted to below the upper border of the patella. The wounds were assessed daily using the ASEPSIS scoring system. In group A, significantly more patients (24%) had an ASEPSIS score > 10, compared to group B (3%) and group C (2%). The mean ASEPSIS score was significantly lower in group C than groups A or B, 1.5 +/- 2.4 vs. 6.5 +/- 3.2 or 3.7 +/- 1.7, respectively. The ASEPSIS score is reduced when vein harvest is restricted to below the level of the knee.

    The scrubbing of hands and forearms using antiseptic agents has been the standard pre-operative procedure to prevent surgical site infection. With the introduction of antiseptic agents, the need to use brushes for pre-operative disinfection has been questioned and it has been recommended that the procedure be abandoned due to the injuries it may cause to the skin. With the purpose to provide the foundations for the efficacy of pre-operative asepsis without using brushes or sponges, the objective of this study was to evaluate three methods of pre-operative asepsis using an antimicrobial agent containing chlorhexidine gluconate - CHG 2%; hand-scrubbing with brush (HSB), hand-scrubbing with sponge (HSS), and hand-rubbing with the antiseptic agent (HRA) only. A comparative crossover study was carried with 29 healthcare providers. Antimicrobial efficacy was measured using the glove-juice method before and after each tested method. Statistical analyses showed there were no significant differences regarding the number of colony-forming units when comparing HRA, HSB, and HSS techniques (p=0.148), which theoretically disregards the need to continue using brushes or sponges for hand asepsis.

    The possibility of transmission of infectious agents during tattooing has become a legitimate issue of concern for health care providers. A collaborative educational program was developed by a county health department, College of Nursing, and tattoo artists to address issues of medical asepsis with the goal of producing a mechanism for certification of tattoo studios. The group's effort was enhanced by recognizing each other's value systems and by the mutual need for a successful program. A framework for developing, implementing, and evaluating community partnerships was addressed. This program demonstrated that community health nurses can play an instrumental role in collaborating with both health care providers and personal-service workers to minimize transmission of infectious agents during cosmetic procedures.

    Full Text Available Pimpinella anisum, is a plant species popularly used as treatment for different diseases, although no studies exist which could prove its pharmacological activity. This species has no known methods of asepsis and adequate conditions to conduct in vitro propagation trials. To assess the most efficient method of seed sterilization and the most favorable concentration of agar and MS salts, five tests of asepsis and tests to evaluate the dry mass increase of germinated seed in 3g/L and 6g/L of agar and MS in concentrations of 0%, 25%, 50%, 75% and 100%, were carried out. The samples that were immersed in a concentration of 2% sodium hypochlorite for 20 minutes and then washed in distilled water produced 100% of sterile plantlets. The greatest increase in dry mass was obtained with 75% and 100% of MS salts. Furthermore, the different concentrations of agar did not influence the percentage of the plantlets dry mass. Pimpinella anisum é uma planta popularmente utilizada como medicinal para diversas enfermidades, embora não existam estudos que comprovem sua atividade farmacológica.

    Full Text Available Background: Banana leaf is used in many centers in India during the care of patients with toxic epidermal necrolysis (TEN and other extensive blistering disorders. Sepsis is an important cause of death in TEN patients and use of banana leaf may be a source of such infection. Aims: We conducted this study to detect the bacterial flora of the banana leaf and to examine various methods of rendering the leaf aseptic. Methods: Five pieces of banana leaf, 2 x 2 cm in size, were cultured separately in blood agar as follows: One piece was heated over a flame and one was soaked in boiling water and one was autoclaved. Methylated spirit was applied over one piece and ignited. One piece was placed on the media, ′as is.′ The Petri dishes were incubated examined after 48 h. Results: All the pieces except the autoclaved specimen of the leaf grew coagulase-negative staphylococci (CONS when aseptic precautions were not maintained and aerobic spore bearers when all aseptic measures were subsequently instituted during the procedure. Conclusion: We recommend measures to prevent possible transmission of bacterial infection by the leaf. Autoclaved and aseptically handled banana leaves may be used to reduce chance of infection in the treatment of TEN.

  14. The white epidemic and the asepsis of refined earthenware in Belle Époque São Paulo.

    Science.gov (United States)

    Souza, Rafael de Abreu E

    2012-12-01

    The article examines Brazilian refined earthenwares known as faiança fina (fine faience) and relates ideas about its production to the contextual backdrop of hygienist discourses in the city of São Paulo in the early twentieth century. Based on an analysis of glaze components, moisture expansion processes, and technological aspects of the production of earthenware recovered from the Petybon archeological site, it is suggested that the establishment of factories and the production and consumption of white ceramics in the city of São Paulo were partially a consequence of the vigorous hygienization policies and modernity projects then advocated by São Paulo's elites.

But he is reminiscent of an extremely skilful surgeon, always having a remarkable high rate of recoveries. For instance when it came to operate on bladder with a perineal approach (vesical cut), only three patients died out of one hundred and twenty operations. One century before Semmelweiss and more earlier than Pasteur, Pouteau thought that hospital-gangrene was not only caused by air miasma but also by direct contact, which could be indebted dirty instruments or hands, or hospital-made bandages. So he advised impeccably cleanliness for surgical students. According to his mind, soap was inadequate for cleaning hospital linen. Those must be pull out of neat material fitted by clean hands out of hospitals. It shall be supplied every day and never gathered inside. In order to keep clear of gangrene, the patient will not wait too long inside hospital. In case of bleeding, cautery must preferable to ligature for Pouteau "We can do without the bitter sadness of seeing a lighter wound become a lethal or incurable one ..." (Posthumous works, vol.

    Science.gov (United States)

    Al-Damouk, M; Pudney, E; Bleetman, A

    2004-02-01

    Hand hygiene and simple aseptic measures before invasive procedures are effective in reducing rates of healthcare-associated infection. The perceived urgency of a clinical situation in the emergency department, however, may influence medical staff's compliance with good practice in infection control. The aims of this prospective, single-blinded, observational study were twofold. First, to assess doctors' compliance with good practice in hand hygiene between patient episodes and asepsis during invasive procedures in the emergency department. Second, to assess the effect of clinical urgency on compliance with good practice in hand hygiene and asepsis during invasive procedures. Good practice standards for asepsis in invasive procedures and hand hygiene between patient episodes were compiled from a literature search. Doctors' compliance with these standards was observed in two emergency departments (UK and New Zealand). Observed clinical cases were classified as immediate, urgent and non-urgent based on the triage system. There was poor compliance with good practice guidelines for asepsis in invasive procedures in both centres. Staff achieved high compliance with the guidelines in only 27% of cases in the UK and 58% of cases in New Zealand. Clinical urgency did not appear to adversely affect compliance with aseptic good practice. Hand hygiene between patient consultations was very low at 14% in the UK and 12% in New Zealand. Asepsis and hand hygiene was poor in both the UK and New Zealand emergency departments. There may be a need for some compromise in standards of asepsis in very sick patients due to the urgency of the clinical situation. Compliance in all situations especially non-urgent procedures needs to be improved.

    Conclusions: Thalassemia is a chronic transfusion dependent disease complicated by the effects of iron overload on various organs leading to increased morbidity and mortality. The risk of transmission of TTI in thalassemia increases with time as number of transfusions increase. Use of advanced technology in blood screening, voluntary donations, donor selection, asepsis during blood transfusion should be used to curtail the transmission.

  10. Prevention of postoperative infections in ophthalmic surgery

    Directory of Open Access Journals (Sweden)

    Ram Jagat

    2001-01-01

    Full Text Available Postoperative endophthalmitis is a serious, vision-threatening complication of intraocular surgery. Better instrumentation, surgical techniques, prophylactic antibiotics and better understanding of asepsis have significantly reduced the incidence of this complication. Postoperative endophthalmitis may occur as an isolated event or as a cluster infection. Topical antibiotics, preoperative periocular preparation with povidone-iodine combined with a sterile operating room protocol significantly reduce the incidence of isolated postoperative endophthalmitis. The role of antibiotics in the irrigating fluid and subconjunctival antibiotics remains controversial. Cluster infections on the other hand are more likely to occur due to the use of contaminated fluids/viscoelastics or a breach in operating room asepsis. Prevention of postoperative endophthalmitis requires strict adherence to operating room norms, with all involved personnel discharging their assigned roles faithfully.

    2016-08-01

    We report an outbreak of healthcare-associated prostatitis involving rare environmental pathogens in immunocompetent patients undergoing transrectal prostate biopsies at Hôpital Édouard Herriot (Lyon, France) during August 13-October 10, 2014. Despite a fluoroquinolone-based prophylaxis, 5 patients were infected with Achromobacter xylosoxidans and 3 with Ochrobactrum anthropi, which has not been reported as pathogenic in nonimmunocompromised persons. All patients recovered fully. Analysis of the outbreak included case investigation, case-control study, biopsy procedure review, microbiologic testing of environmental and clinical samples, and retrospective review of hospital records for 4 years before the outbreak. The cases resulted from asepsis errors during preparation of materials for the biopsies. A low-level outbreak involving environmental bacteria was likely present for years, masked by antimicrobial drug prophylaxis and a low number of cases. Healthcare personnel should promptly report unusual pathogens in immunocompetent patients to infection control units, and guidelines should explicitly mention asepsis during materials preparation.

    Full Text Available Valvular heart disease in systemic lupus erythematosus (SLE is associated with substantial morbidity and mortality. Current therapy includes symptomatic measures and valve replacement. SLE can present major challenges because of accrued organ damage, coagulation defects and complex management regimes. The peri-operative goals are to maintain strict asepsis, avoid use of nephrotoxic drugs and thereby renal insult, and to promote early ambulation post-operatively.

    The First World War because of the use of new weapons, injured more than 3 500 000 people (500 000 in the face), more than diseases (tuberculosis, typhoid fever, etc.) or even weather circumstances. The healing of the war wounds through surgery undertook a significant evolution thanks to the use of asepsis and antiseptics. Mortality go down, opening the way to the physical and psychological rehabilitation of those injured by the war.

    1996-01-01

    Positive blood cultures in very low birthweight or preterm infants usually reflect bacteraemia, septicaemia, or failure of asepsis during sampling and lead to increased costs and length of stay. Rates of nosocomial, or hospital acquired, bacteraemia may therefore be important indicators of neonatal unit performance, if comparisons are adjusted for differences in initial risk. In a preliminary study the risk of nosocomial bacteraemia was related to initial clinical risk and illness severity me...

    Surgical site infection (SSI) is a common complication after abdominal surgery and the Centers for Disease Control and Prevention (CDC) criteria are commonly used for diagnosis and surveillance. The aim of this study was to evaluate whether SSI diagnosed according to CDC is clinically relevant (CRSSI) and whether there is agreement between evaluations according to the CDC criteria, the ASEPSIS score (Additional treatment, presence of Serous discharge, Erythema, Purulent exudate, Separation of the deep tissues, Isolation of bacteria and duration of Stay) and CRSSI. We included 54 patients diagnosed with SSI and a matched control group (N=46) without SSI according to the CDC criteria after laparotomy. Two blinded experienced surgeons evaluated the hospital records and determined whether patients had CRSSI, based on the following criteria: antibiotic treatment, surgical intervention, prolonged hospital stay or referral to an intensive care unit for SSI. The rate of CRSSI was 38 of 54 (70%) in patients with CDC-diagnosed SSI and none in patients without a CDC-diagnosed SSI. Sixty-one percent of the CDC-diagnosed SSIs were superficial, of which 48% were considered clinically relevant. There was substantial agreement between the CDC criteria and CRSSI [kappa=0.69; 95% confidence interval (CI): 0.55-0.83] and fair agreement between the ASEPSIS score and the CDC criteria (kappa=0.23; 95% CI: 0-0.49) and between the ASEPSIS score and CRSSI (kappa=0.39; 95% CI: 0.17-0.61). The CDC criteria represent a suitable standard definition for monitoring and identifying SSI, even if some cases of less clinically significant superficial SSI are included.

  18. Cutaneous and systemic complications associated with tattooing.

    2016-06-01

    Tattooing can result in a wide variety of complications, whose prevalence and incidence remain still unclear. Hypersensitivity reactions (or allergies) to tattoo pigments are currently the most common complication on a tattoo, however they are not predictable. Infections are nowadays directly related to the lack of asepsis and hygiene during the tattooing procedure or during the healing phase. Patients with a known cutaneous disease should be warned of a potential risk of localization of their disease to the tattoo. A skin eruption restricted to a tattoo may reveal sarcoidosis. Patients with chronic conditions and/or impaired immunity should discuss with their physician about the possibility and when to have a tattoo.

    Ozone is a strong oxidizing biocide that has broad-spectrum antimicrobial properties. The aim of the study was to compare the efficacy of ozone to a propanol-based hand rub for hand disinfection. Twenty subjects were enrolled in an in-vivo cross-over trial (prEN 12791). Subjects treated their hands with the reference procedure (propan-1-ol 60%) or with ozone (4 ppm). Post-wash bacterial counts were determined from one hand (immediate effect), and from the other hand that had been gloved for 3h (delayed effect). The investigation indicated that ozone is inferior to propan-1-ol 60% hand rub for hand asepsis.

    On June 14, 1905, Johann Anton von Mikulicz-Radecki, one of the most famous surgeons of the time, died. He was a disciple of famous Theodor Billroth of Vienna and the teacher of Ferdinand Sauerbruch in Breslau. Mikulicz-Radecki's merits in the field of the history of medicine are based on his achievements in developing the system of antisepsis and asepsis. He also devoted himself to urological surgery, and his name is linked with diseases, operations, and construction of new medical instruments. Mikulicz-Radecki created two surgical schools, one in Cracow and a second one in Breslau, where he worked for over 15 years until his death.

    Conclusions: Acute PID is common among young, single women with multiple sexual partners, who should be regularly screened for the various sexually transmissible infections. The micro-organisms frequently responsible for acute PID were genital tract mycoplasmas, whose identification should be included among the routine tests done to women with acute PID. Cases of acute PID due to intra-uterine procedures reminds us that adequate asepsis should be observed during these procedures. [Int J Reprod Contracept Obstet Gynecol 2015; 4(3.000: 809-813

    The principles of surgical asepsis apply to field surgeries with few exceptions. The minimum level for performance of surgeries in the field on free-ranging animals should be the same as for domestic animals undergoing surgery in animal hospitals. Surgeries in the field are typically done as part of research and management projects and usually involve a combination of biologists and veterinarians with the possibility of conflicts in scientific cultures. This article outlines a minimum standard of care for field surgeries and will serve as a resource for Institutional Animal Care and Use Committees and biologists and veterinarians planning projects that involve surgeries on free-ranging wildlife in field conditions.

    Dental extraction is a surgical act frequently carried out in the African dental structures. It requires the rigorous respect of the conditions of asepsis and antisepsis. Equipments and anaesthetic and avulsional products must be also sufficient. Our study undertaken among 46 dental services in areas health centers of Senegal aimed to determine the conditions under which dental extractions are carried out. The principle results of our study showed that 93% of dental practitioners wore sterilized gloves. 49% of the dentist's care activity consisted in dental extractions. 50% of the practitioners re-use anaesthetic needles, 2% re-use anaesthetic carpules. We noticed that the dental structures were facing a deficit of materials and products of extraction. Face to the outbreak of serious illnesses as infections of HIV and Hepatitis B, the practitioner and his team must be sensitized and trained to struggle against the transmissible infections and to carry out the dental extraction only if the conditions of asepsis and antisepsis are joined together. A pleading towards the medical authorities must be done to support the services in equipments and periodic renewals of the materials and products of extractions.

  4. Surgery, sterilization and sterility.

    Science.gov (United States)

    Green, V W

    1993-03-01

    The history of sterilization was not linked from the first with surgery. Surgery came first, fully 600 years before the principles of asepsis and anesthesia were even introduced in the middle of the 1800s. Also in the 1800s, the beginnings of thermal sterilization were being developed in the food industry. The basic principles of antisepsis and prevention of wound suppuration, including the destruction of germs on instruments, dressings, the hands of the surgeon and his assistants, and everything else in contact with the wound were clearly elucidated by Lister in the 1870s and remain the inviolate principles of surgical asepsis today. In general, the marriage between the surgeons and the sterilizers was a successful one; the major handicap to eternal bliss and harmony, however, was an incompatibility between the partners. As in many marriages, the partners made unwarranted demands upon each other, and became frustrated when these demands were unfulfilled. The field of surgical sterilization and surgical safety is less confused by technical inconsistencies than it is by semantic nightmares, such that we will never reach a universal definition of sterility. However, we do not really need a universal definition of sterility. Rather we should learn how to translate sterility tests in terms of the real world infections hazards.

  5. Pathogenicity of aseptic Bursaphelenchus xylophilus.

    Li-hua Zhu

    Full Text Available Pine wilt is a disease of pine (Pinus spp. caused by the pine wood nematode (PWN, Bursaphelenchus xylophilus. However, the pathogenic mechanism of pine wilt disease (PWD remains unclear. Although the PWN was thought to be the only pathogenic agent associated with this disease, a potential role for bacterial symbionts in the disease process was recently proposed. Studies have indicated that aseptic PWNs do not cause PWD in aseptic pine trees, while PWNs associated with bacteria cause wilting symptoms. To investigate the pathogenicity of the PWN and its associated bacteria, 3-month-old microcuttings derived from certain clones of Pinus densiflora Siebold & Zucc. produced in vitro were inoculated under aseptic conditions with aseptic PWNs, non-aseptic PWNs and bacteria isolated from the nematodes. Six-month-old aseptic P. densiflora microcuttings and 7-month-old P. massoniana seedlings were also inoculated under aseptic conditions with aseptic PWNs and non-aseptic PWNs. The results showed that the aseptic microcuttings and seedlings inoculated with aseptic PWNs or non-aseptic PWNs wilted, while those inoculated with bacterial isolates did not wilt. Nematodes were recovered from wilted microcuttings and seedlings inoculated with aseptic PWNs and non-aseptic PWNs, and the asepsis of nematodes recovered from aseptic PWN-inoculated microcuttings and seedlings was reconfirmed by culturing them in NB liquid medium at 30°C for more than 7 days. Taken together, the results indicate that the asepsis of PWN did not cause the loss of pathogenicity.

    We report an outbreak of healthcare-associated prostatitis involving rare environmental pathogens in immunocompetent patients undergoing transrectal prostate biopsies at Hôpital Édouard Herriot (Lyon, France) during August 13–October 10, 2014. Despite a fluoroquinolone-based prophylaxis, 5 patients were infected with Achromobacter xylosoxidans and 3 with Ochrobactrum anthropi, which has not been reported as pathogenic in nonimmunocompromised persons. All patients recovered fully. Analysis of the outbreak included case investigation, case–control study, biopsy procedure review, microbiologic testing of environmental and clinical samples, and retrospective review of hospital records for 4 years before the outbreak. The cases resulted from asepsis errors during preparation of materials for the biopsies. A low-level outbreak involving environmental bacteria was likely present for years, masked by antimicrobial drug prophylaxis and a low number of cases. Healthcare personnel should promptly report unusual pathogens in immunocompetent patients to infection control units, and guidelines should explicitly mention asepsis during materials preparation.

    Investigators of our research facility generally accept the concept of asepsis as an important component of adequate surgical care for animals. However, they experience difficulties putting it into practice, especially in the case of rodents. The reasons for this are inconvenience, cost, and lack of training. To better assist investigators in the implementation of aseptic surgical techniques in their laboratories, we have created an Operating Room (OR) Committee modeled after OR committees found in human hospitals. A reconstructive surgeon, a veterinarian, a research scientist, a nurse involved in the training of OR personnel, interns, graduate students, and an animal health technician were chosen as committee members in light of their OR and animal care expertise. The first task of the OR Committee was to establish institutional guidelines for aseptic surgery, taking into account the costs imposed on research budgets by these procedures. The OR Committee also supports a complete training program in aseptic surgery techniques, which consists of lectures, a training manual, videos, and a practical course. Furthermore, when experimental procedures require specialized equipment, the OR Committee collaborates with researchers to develop strategies to achieve asepsis. This OR Committee and the training program proved to be important tools to promote and improve the quality of animal care during surgery.

    A urethral dysuria cystograph (CUMS (Cistografia Ureteral Miccional Seriada)) is the first diagnostic procedure, by means of x-rays, to evaluate bladder-urethral reflux. It consists of a bladder catheter to administer a radiopaque contrast dye through the ureter. To use the aforementioned technique without any asepsis measures and without knowledge about it can lead to possible complications. By means of a retrospective study using a sample of 181 patients, the authors have evaluated the incidence of possible complications and/or subsequent discomfort due to a urethral dysuria cystograph (CUMS). As final results, by means of an after test telephone call, the authors observed that 96.7% of the children who underwent this technique did not manifest any type of complication nor urinary discomfort.

    Butreau-Lemaire, M; Botto, H

    1997-09-01

    The concept of nosocomial urinary tract infection now corresponds to a precise definition. It is generally related to bladder catheterization, constitutes the most frequent form of nosocomial infection (30 to 50% of infections), and represents the third most frequent portal of entry of bacteraemia. The organism most frequently isolated is Escherichia coli; but the flora is changing and the ecological distribution is continually modified. Despite their usually benign nature, these nosocomial infections can nevertheless influence hospital mortality; they increase the hospital stay by an average of 2.5 days and their treatment represents a large share of the antibiotic budget. Prevention of these infections is therefore essential, with particular emphasis on simple and universally accessible measures: very precise indications for vesical catheterization, use of closed circuit drainage, maximal asepsis when handling catheters, after washing the hands.

    Complications resulting from IUD use are essentially of 4 types: 1) uterine perforation, either at the time of insertion or by translocation of the device. Perforations can be avoided by exercising the utmost attention at time of insertion, and by choosing the proper time of insertion, usually postmentruation. It is also imperative that the IUD be right for the uterine cavity size; 2) pelvic infection, the most serious of IUD complications, since it can, however rarely, cause death; it is absolutely necessary to observe the strictest asepsy during IUD insertion; 3) menorrhagia, which, when severe, can cause anemia. Women with heavy menstrual flow should not wear an IUD; and, 4) ectopic pregnancy, which usually ends in spontaneous abortion, but which can cause infection.

    Alexis Carrel was a French surgeon in the 20th century. He made significant contributions to many advances in the fields of vascular surgery, cardiothoracic surgery and organ transplantation. He demonstrated that blood vessels can be united end-to-end and pioneered the triangulation suturing technique in vascular anastomosis. The methods he developed are still in use to this day. He insisted on the importance of absolute asepsis in vascular surgery when such practices were almost unheard of. He was also considered the father of solid organ transplantation. He was awarded the Nobel Prize in recognition of his work. Together with Charles Lindbergh, he developed the extracorporeal perfusion pump to keep organs alive outside the human body. His contribution to medicine also extended to tissue culture and wound management. He was one of the most controversial figures of his generation, believing in the idea of genetic superiority and eugenics and he was associated with fascism in the 1930s.

    Full Text Available Introduction, definition, rationale and scope: Dermatologists in India are now increasingly performing surgical and cosmetic procedures in their practice. This calls for minimum standards at the national level with the main focus of patient safety and hence the guidelines for setting up a dermatosurgical theatre. Facility: The dermatosurgery theatre can be created in either physician′s clinic, or a hospital depending on the procedure to be performed. The dermatosurgery theatre requires careful planning with regards to - location, dimension, shell design, lighting, electrical requirements, operation table, chair, trolley, surgical instruments, sterilization of devices, asepsis and advanced life support. Apart from physical considerations, other considerations including theatre etiquettes, consent for surgery, safety of dermatosurgeon, theatre staff and lastly biomedical waste management should be looked into. These issues are discussed in detail in the recommendations.

    The aim of this study is to experiment with the feasibility of the fractionation of radiopharmaceuticals cases on a majority of cases for labelling to technetium 99m at a temperature of -16 celsius degrees and -80 celsius degrees. The cases are pharmaceuticals to inject. They must have an obligatory asepsis. At every labelling, a monitoring of the radiochemical purity is completed by thin layer chromatography, by chromatography on paper, by high performance liquid chromatography. By the technique of fractionation studied here, a conservation at -16 degrees Celsius is enough for the diphosphonate, the albumin aggregates, the tetrofosmin and the phytate. for the H.M.P.A.O., the M.A.G.3, the D.M.S.A. and the biliary tracers it is necessary to have a conservation mean at very low temperature. The fractionation is a technique in nuclear medicine that dose not give any difficulties and can become a usual practice in nuclear medicine. (N.C.)

    2011-01-01

    Concerns have been raised about whether it is possible to perform aseptic procedures within a community setting. Hallett (2000) has described how community nurses often have a fatalistic view about whether such procedures can really be performed at home. At the same time there has been an increase in the number of patients being cared for at home who need interventions which must adhere to the principles of asepsis. While it has been acknowledged for some time that community nurses must be resourceful and adapt the procedure, the view that community nurses cannot really perform aseptic procedures is a fairly new phenomenon. This article explores the reasons why concerns about the performance of aseptic procedures in the community may have arisen and what steps can be taken to address these concerns to ensure that care at home is both safe and effective.

    Root growth in space is discussed and observations on root production from plants flown as part of the Chromex project that were defined as to their origin, stage of development and physiological status, are presented. Roots were generated from fully differentiated, aseptically maintained individuals of Haplopappus gracilis (Compositae) under spaceflight conditions. Results are compared for tissue culture generated plantlets and comparably sized seedling clone individuals, both of which had their roots trimmed on Earth before they were loaded into NASA's plant growth unit and subjected to a 5 day shuttle flight (STS-29). Asepsis was maintained throughout the experiment. Overall root production was 40 to 50 percent greater under spaceflight conditions than during ground control tests. However, root formation slowed down towards the end of the flight. This decrease in new roots did not occur in the ground controls that sought to simulate flight except for microgravity.

    Disinfection and maintenance of an acceptable level of asepsis in spacecraft potable water delivery systems is a formidable task. The major area of research for this project has been to monitor the formation and growth of biofilm, and biofilm attached microorganisms, on stainless steel surfaces (specifically coupons), and the use of ozone for the elimination of these species in a closed loop system. A number of different techniques have been utilized during the course of a typical run. Scraping and sonication of coupon surfaces with subsequent plating as well as epifluorescence microscopy have been utilized to enumerate biofilm protected Pseudomonas aeruginosa. In addition, scanning electron microscopy is the method of choice to examine the integrity of the biofilm. For ozone determinations, the indigo decolorization spectrophotometric method seems most reliable. Both high- and low-nutrient cultured P. aeruginosa organisms were the target species for the ozone disinfection experiments.

    Full Text Available Evolvement of urology as a separate scientific discipline depends on several factors. Endoscopic diagnostics, radiological diagnostics, and operative techniques in general surgery, had provided an ability to perform more complex and longer operations. Urology had evolved from the great schools of surgery in Germany and France, and their the most important surgeons, who were intersted in urological surgery. The first endoscope was introduced in 1806, and received today’s form in 1879. Application of "X" rays in medicine started in 1895, and it was later applied as a cystography, retrograde pyelography as well as intravenous urography. The most important thing for the operative technique evolution were application of anhestesia, asepsis and new hemostatic devices. During the one century long development, urology had passed the way from completely unknown field, up to the discipline with the best diagnostic preciseness.

    Les méningites sont des complications rares mais graves des anesthésies péridurales et des rachianesthésies. Les méningites bactériennes sont essentiellement dues à des cocci à Gram positif, ce qui sous-entend une contamination exogène pouvant être le témoin d'une faute d'asepsie. L’évolution est le plus souvent favorable sous traitement, mais au prix d'un accroissement des dépenses de santé et parfois d'importantes séquelles neurologiques. Nous présentons un cas de méningite bactérienne au décours d'une rachianesthésie effectué pour césarienne. PMID:27642477

    Staphylococcus epidermidis is a pathogenic organism with increasing importance in total parenteral nutrition therapy. Strict asepsis during catheter insertion prolongs the interval free from Staphylococcus epidermidis infection. Staphylococcus epidermidis colonizes the catheter after migrating from the skin. For protection, we advise a long subcutaneous tunnel for all catheters that are to be indwelling for longer than three weeks. Prompt recatheterization of a patient with Staphylococcus epidermidis sepsis can result in hematogenous seeding of the new catheter and persistence of the infection. Catheter related Staphylococcus epidermidis sepsis has subsided after catheter withdrawal, and there is no need for antibiotic therapy provided that other prosthetic materials are not placed in the vascular tree. Immunologic status of the patients is not related to the frequency or severity of Staphylococcus epidermidis infections, or both.

    Full Text Available Gingival recession may cause cosmetic changes and root hypersensitivity, which can alter mastication and tooth brushing, and thus contribute to the progression of periodontal disease. Treatment of gingival recessions with subepithelial conjunctive tissue grafting is very predictable due to its bilaminar nature. However, some factors may influence the success of the procedure, among them: selection of the lesion; characteristics of the defect with regard to the depth and width of the recession, the deeper and wider the recession, the worse the prognosis, and also the presence of restorations. Furthermore, it is necessary to control the etiologic factors of recessions, such as inflammation and traumatic brushing, control of systemic factors, occlusal trauma, smoking and harmful habits, technical considerations and asepsis. The success of the procedure must be based on observing the possible factors that might influence their predictability, as well as respecting the basic principles of mucogingival surgery.

    Vaccinia virus (VACV) is the cause of bovine vaccinia (BV), an emerging zoonotic disease that affects dairy cows and milkers. Some chemical disinfectants have been used on farms affected by BV to disinfect cow teats and milkers' hands. To date, there is no information about the efficacy of disinfectants against VACV. Therefore, this study aimed to assess the virucidal activity of some active disinfectants commonly used in the field. Sodium hypochlorite, quaternary ammonium combined with chlorhexidine, and quaternary ammonium combined with glutaraldehyde were effective in inactivating the virus at all concentrations tested. Iodine and quaternary ammonium as the only active component were partially effective. The presence of bovine feces as organic matter and light decreased the effectiveness of sodium hypochlorite. These results show that an appropriated disinfection and asepsis of teats and hands may be helpful in the control and prevention of BV and other infections with VACV. PMID:21734141

  9. A novel approach to the statistical evaluation of media fill tests by the difference from no contamination data.

    2004-01-01

    It is obvious that, in the media fill test and process simulation test, positive numbers in total fills should not have any significant difference from zero or asepsis. There are many reports concerning the definition of "sterility" or "asepsis." However, any scientific and practical methods to demonstrate "no significant difference from zero" have not been reported up to now. The existing criteria, such as "less than 0.1%," "less than 0.05%," and "less than two positives" are not appropriate to assure the integrity of processes, and sometimes lead to erroneous results. The purpose of this report is to demonstrate novel, reasonable and practical methods and criteria based on scientific and statistical consideration. According to the ISO 13408-1 Aseptic Processing of Health Care Products, Part 1 (1998), General Requirement for Aseptic Processing, the action level for the number of positive units in media fill tests is specified as 0.1%, and the alert level is 0.05%. In this paper it is shown that the existing ISO standard and other official methods are inappropriate in that zero contaminated units (sterile product) is outside the confidence range of probable distribution of contaminated units, even though the contaminated units are less than 0.1% in larger numbers of fills, and even less than 0.05%. This indicates that the limit of 0.1% or 0.05% is inappropriate in cases of larger numbers of fills. For sterile products, the number of contaminated units other than "zero" at the statistical confidence range must be judged to be contaminated units in process and as non-sterile. In order to harmonize this criteria-"no significant difference from zero"-with the existing criteria, the new criteria may be combined with only the existing criteria of 0.05% in smaller number of fills.

    The concept of core competencies in graduate medical education was introduced by the Accreditation Council for Graduate Medical Education of the American Medical Association to semiquantitatively assess the professional performance of students, residents, practitioners, and faculty. Many aspects of the career of J. Marion Sims, MD, are exemplary of those core competencies: MEDICAL KNOWLEDGE: Author of the first American textbook related to gynecology. MEDICAL CARE: Innovator of the Sims' Vaginal Speculum, Sims' Position, Sims' Test, and vesico-/rectovaginal fistulorrhaphy; advocated abdominal exploration for penetrating wounds; performed the first cholecystostomy. PROFESSIONALISM: Served as President of the New York Academy of Medicine, the American Medical Association, and the American Gynecologic Society. INTERPERSONAL RELATIONSHIPS/COMMUNICATION: Cared for the indigent, hearthless, indentured, disenfranchised; served as consulting surgeon to the Empress Eugénie (France), the Duchess of Hamilton (Scotland), the Empress of Austria, and other royalty of the aristocratic Houses of Europe; accorded the National Order of the Legion of Honor. PRACTICE-BASED LEARNING: Introduction of silver wire sutures; adoption of the principles of asepsis/antisepsis; adoption of the principles of general anesthesia. SYSTEMS-BASED PRACTICE: Established the Woman's Hospital, New York City, New York, the predecessor of the Memorial Sloan-Kettering Center for the Treatment of Cancer and Allied Diseases; organized the Anglo-American Ambulance Corps under the patronage of Napoleon III. What led him to a life of clinical and humanitarian service? First, he was determined to succeed. His formal medical/surgical education was perhaps the best available to North Americans during that era. Second, he was courageous in experimentation and innovation, applying new developments in operative technique, asepsis/antisepsis, and general anesthesia. Third, his curiosity was not burdened by rigid

    Full Text Available The neonatal mortality rate in India is high and stagnant. Special Care Newborn Units (SCNUs have been set up at different levels of Health Care Delivery System to provide quality newborn-care services in several hospitals to meet this challenge. Many units are located in the districts where the burden of neonatal deaths is high, and access to special newborn care is poor. The study was conducted to assess the functioning of SCNUs in six centers of India. The evaluation was based on an analysis of secondary data from the six units that had been functioning for at least three year. A cross-sectional survey was also conducted to assess the availability of Quality care and Aseptic practices implemented at different levels of SNCUs. Descriptive statistics were used for analyzing the inputs (Quality care and aseptic practices and outcomes (morbidity and mortality. The rate of mortality among admitted neonates was taken as the key outcome variable to assess the performance of the units. Chi-square test was used for analyzing the trend of case-fatality rate over a period of 3 years considering the first year of operationalization as the base. Correlation coefficients were estimated to understand the possible association of case-fatality rate with factors, such as bed:doctor ratio, bed:nurse ratio, average duration of stay, and bed occupancy rate, and the asepsis score was determined. The rates of admission increased from a median of 16.7 per 100 deliveries in 2012 to 19.5 per 100 deliveries in 2014. The case-fatality rate shows progressive decline in all the units in Last 3 years. Proportional mortality due to sepsis and low birthweight (LBW declined significantly over two years (LBW <2.5 kg. The major reasons for admission and the major causes of deaths were birth asphyxia, sepsis, and LBW/prematurity. The units had a varying nurse:bed ratio (1:1-1:2.14. The bed occupancy rate ranged from 83% to 121% (median 115%, and the average duration of stay

    Hygiene and asepsis of the dental office depend on medical ethics and legal obligation. The survey done with the participation of 33 practitioners over the 42 practicing in Yaounde allows apprehending the reality of the daily hygiene. The ways of cleaning, decontamination, disinfection or of sterilization of the premises, the dental equipment and instruments, hand-washing, disposable materials and the vaccination protection of the practitioners were analyzed. The cleaning of the floor and door mats is daily (100%); disinfection is done daily in 83% of the departments in all of the centers. The cleaning and disinfection of the dental chair is daily and is done using soap (23%) and/or bleaching-water (56%). Cleaning or disinfection of the suction machine is done with soap (24%) or with bleaching-water (47%). The hand-pieces and the turbines are cleaned and/or disinfected after each usage in (94%) with alcohol (17%) or with bleaching-water (32%) and sterilized with a heat sterilizer (45%), an autoclave(40%) or cold disinfected(15%). The frequency of the treatment of the instruments is well-respected (83%). Nevertheless the products used are very varied and are not always used in the prescribed order. Hand-washing is systematic after each patient; 50% of the practitioners use soap bars or powered soap and 50% use an antiseptic or a disinfectant solutions. With the regard to the vaccination, only 3 practitioners were properly vaccinated against hepatitis B, tetanus, diphtheria, poliomyelitis and tuberculosis. With regard to the protection of the practitioners, 72% do not wear caps, 56% do not wear eyeglasses, 40% do not wear masks, 95% do not use rubber dams, 56% do not disinfect the radiographic films and 37% do not disinfect the impressions; the habitual attire consists of a smock worn over street clothes (78%) and street shoes (90%). The debris is burnt in 35% of the centers. Better knowledge of the different stages (cleaning, decontamination, disinfection or

    The ectosymbiont actinobacterium Pseudonocardia was isolated from the integument of Acromyrmex leaf-cutter ants and seems to play a crucial role in maintaining asepsis of the nest. Currently, there has been an intensive search for Pseudonocardia associated with several attine species, but few studies have indicated that other actinobacteria may be associated with these ants as well. We therefore characterized the culturable actinobacteria community associated with the integument of the fungus-growing ant Acromyrmex subterraneus brunneus Forel, 1893 (Hymenoptera: Formicidae). Ectosymbionts were isolated using four different media and characterized by morphological and molecular (16S rDNA) methods. A total of 20 strains were isolated, of which 17 were characterized as Streptomyces spp., and one isolate each as Pseudonocardia, Kitassatospora and Propionicimonas. Unlike other Acromyrmex species, A. subterraneus brunneus is associated with a diversity of actinobacteria. Even though Pseudonocardia is present on this leaf-cutting ant's integument, the number and diversity of Streptomyces spp. found differs from those of previous studies with other attine ants and suggest that different culturing approaches are needed to characterize the true diversity of microbes colonizing the integument of attine ants. Moreover, understanding the diversity of the culturable actinobacteria associated with A. subterraneus brunneus should increase our knowledge of the evolutionary relationship of this intricate symbiotic association.

    Postoperative wound infection can greatly prolong hospital stay after cardiac surgery, so the identification of predisposing factors may help in prevention or early institution of treatment. Transfer of organisms from the leg to the sternum during coronary artery surgery has been proposed as a major additional cause of sepsis. The definition of wound infection is not standardised and therefore makes comparison between centres difficult. In a prospective study of 517 patients, a wound scoring method (ASEPSIS) has been used to register all abnormal wounds to maximise the chances of identifying factors predisposing to infection. Abnormal healing was noted in 99 (19%) sternal wounds and 29 (8%) leg wounds. Obesity was the principal risk factor (P less than 0.005). Diabetes, reoperation, length of preoperative hospital stay, age, sex, or previous cardiac surgery had little effect on wound healing. The range of bacteria isolated from chest wounds after coronary artery surgery was similar to that after valvular surgery, but the rate of isolation was significantly greater. With careful attention to technique, leg wound infection rarely presented a clinical problem and did not appear to be a source of bacteria infecting the chest wound.

    Comparison of postoperative surgical wound infection rates between institutions and over time is only valid if standard, valid and reliable definitions are used. The aim of this review was to assess evidence of validity and reliability of the definition and measurement of surgical wound infection. A systematic review was undertaken of prospective studies of surgical wound infection published over a seven-year period; 1993-1999. The information extracted from individual studies included: definition of surgical wound infection; details of wound assessment scale, scoring or grading scale systems; and evidence of assessment of validity, reliability and feasibility of identified definitions and grading systems. Two independent reviewers appraised 112 prospective studies, 90 of which were eligible for inclusion; eight studies assessed validity and/or reliability. Forty-one different definitions of surgical wound infection were identified, five of which were 'standard' definitions proposed by multi-disciplinary groups. Presence of pus was the most frequently used single component of any definition; the CDC definitions of 1988 and 1992 were the most widely implemented standard definitions; and the ASEPSIS wound assessment scale was the most frequently used quantitative grading tool. Only two formal validations of a definition were found, and six studies of reliability. This review highlights the extent of variation in definition of surgical wound infection used in clinical practice, and the need for validation of both content and organization of a surveillance system. However, realistically, there will have to be a balance between the quality of the measurement and the practicality of surveillance.

    Introduction Female sterilization is one of the best and effective methods of contraception for women who have completed their family. Tubectomy during caesarean operation and minilaparotomy are popular methods in developing countries whereas laparoscopic sterilization and hysteroscopic tubal occlusion are the preferred methods in developed countries. Aim To know the trends, incidence and immediate complications of methods of female sterilizations performed at our institute. Materials and Methods This is a retrospective analytical study conducted at our tertiary care centre from January 2010 to December 2014 in Karnataka Institute of Medical Sciences, Hubli, Karnataka. The case files of all the patients who underwent sterilization were taken from the medical records section and reviewed in detail. The cases were grouped as caesarean tubectomy, minilaparotomy and laparoscopic sterilization, based on the abdominal entry. For minilaparotomy and during caesarean tubectomy, modified pomeroy’s technique was used. For laparoscopic sterilization, falope rings were used. Data was analysed by Karl Pearson’s correlation co-efficient method and Chi-Square test. The p-value asepsis could be compromised when female sterilization is done in large numbers in camps. Hence target related approach towards female sterilization should be avoided. Laparoscopic sterilization has more procedure related complications, which can be better handled in tertiary care centres. PMID:26894125

    Full Text Available INTRODUCTION Central venous catheters (CVC are used in the treatment of critically ill patients. Indications for placement of CVCs include hemodynamic monitoring, administration of intravenous fluids, medications and total parenteral nutrition. MATERIAL AND METHODS We investigated risk factors and effects of glycopeptide antibiotics on the development of central venous catheter-related infections in 300 patients treated in intensive care units. A semiquntitative culture technique was used. The investigation included: age, diagnosis on admission, catheter insertion site, catheter duration, the first or next catheter and using of glycopeptide drugs. RESULTS 91 catheters (30.3% were colonised, catheter-related infection was found in 50 catheters (16.7%. Infections were more frequent in catheters inserted through the internal jugular vein than in subclavian venous catheters; they were also more frequent if duration of catheterization was longer than seven days, but less frequent in patients who received glycopeptide antibiotics. The isolated microorganism was Staphylococcus aureus. DISCUSSION According to the literature, a number of catheter-related risk factors for infections include: insertion site, type of catheter, the number of manipulations, inadequat asepsis, lumen number, type of antiseptic. The relative importance of one risk factor over another is difficult to assess, given that studies have no priority report. CONCLUSION The duration of catheterization and the insertion site were the most frequent risk factors for infection. The use of glycopeptide antibiotics during catheterization has protective effects.

The method used for the health test was the blotter test and, for the germination, gerbox had been used with paper substratum at temperature of 30ºC under constant light regime. The seeds, as much in the health test as in the germination, tests were sub sampled in one part that was submitted to superficial desinfestation with sodium hypochlorite of, and one part that wasn't. The fungi transmission had been evaluated through lesions found in the seedlings, during the germination test. Sixteen fungi had been identified and quantified: Cladosporium sp., Alternaria alternata, Epicoccum sp., Phoma sp., Geotrichum sp., Penicillium sp., Trichothecium sp., Phomopsis sp., Drechslera sp., Aspergillus spp., Curvularia sp., Fusarium spp., Macrophomina phaseolina, Nigrospora sp., Lasiodiplodia theobroma and Septoria sp. In general , the asepsis provided a drastic reduction in the incidence of all fungi, in both species, with an avarege rate of 90%. Like this, it can be inferred that most of the fungi was contaminating the seeds. The percentage of normal seedlings had not been interfered directly by the fungi. The asepsis reduced the germination in 64%, indicatinwas fitotoxic. In the transmission it had been observed, on average, 17% and 10% of seedlings with symptoms, in the samples without asepsis and with asepsis, respectively. The most frequent fungi transmitted by the ipê-amarelo and ipê-roxo seeds had been: Alternaria alternata, Fusarium spp., Aspergillus spp., Phoma sp. and Phomopsis sp.

    The purpose of this project was to evaluate e-learning versus classroom instruction in infection control by comparing outcomes of multiple-choice examination scores and clinical competency-based examinations (CBE) between two groups of first-year dental hygiene students (fall 2008 e-learning: n=26; fall 2009 classroom instruction: n=26). Contents of both instructional units were comparable and were developed by the Organization for Safety, Asepsis, and Prevention. All students in each group were required to complete infection control instruction as part of the preclinical curriculum (didactic and clinical) and were tested on the material using the multiple-choice examination and clinical CBE. Both groups' scores on the multiple-choice examination ranged from 74 percent to 94 percent (n=26 to 33 of 35), with e-learning mean score=82.8 percent, n=29 of 35, and classroom instruction mean score=86.8 percent, n=30 of 35. A two-tailed independent samples t-test indicated a statistically significant difference between the two groups on the multiple-choice examination (p=0.11). The Fisher's exact test indicated no statistically significant difference between the two groups on the first-time pass rate for the clinical CBE (p=0.668). Findings demonstrated little difference between the two methods for teaching infection control. Thus, either method may be chosen. Future research should examine a blended approach with larger samples and longitudinal data.

    Full Text Available The seriousness of postoperative infections and the increased susceptibility of patients undergoing cardiac surgery increase the demand for the operating theatre (OT asepsis to prevent bacterial infections. In fact, the organisms carried by the air reach the wound after having sedimented onto sterile field. The air represents a critical point for quality control of air filtration systems, for sanitization procedures and for the evolution of hygienic features of the OT environment.Aim of the study is to evaluate the prevalence of microorganisms found in the operating rooms (OR air monitoring in the Salam Center for Cardiac Surgery of Khartoum (Sudan between July 2008 and March 2009.The specimens were collected every month in two different times: “OR at rest” (after sanitization and “OR operational”, using sedimentation method (Fisher 1972. Results showed that each sample collected at rest had IMA (index of microbial air contamination < 5CFU/plt, whereas the bacterial growth was between 25 and 50 CFU/plt when the samples had been collected in the same places during operating activities.This indicate the effectiveness of sanitization procedures and confirm that people working in OT are an important source of bacteria causing postoperative infections. Coagulase negative Staphylococci, Gram negative bacillus and Staphylococcus aureus spp. were the predominant organisms isolated.

    Full Text Available Background: Strict asepsis is necessary in operating theatres (OT and intensive care units (ICU as the patients undergo invasive procedures. The filters of contaminated air conditioning (AC units provide a niche for proliferation of fungi and production of fungal spores. Methods: The routine procedure for maintenance of sterile atmosphere in our hospital, i.e. fumigation and mopping walls with disinfectants often fail to address these fungal spores of the AC filters. We therefore carried out a surveillance of the ACs in ICUs and OTs to find the level of contamination with fungal spores and also to improvise on intervention strategies to tackle the problem. Over 3 months period, 34 ACs from 7 OTs and 2 ICUs were screened by taking 2 swabs from each AC which were then tested for the presence of fungal spores as per standard methods. Results: The contamination rate was 88.2% before fumigation and 76.9% after fumigation. The fungal spore contamination rate was reduced to 20% (1 out of 5 ACs after servicing of the ACs was done. Aspergillus spp. was the most common fungal isolate. Conclusion: Based on the observations, we recommend regular servicing of the ACs as well as wet mopping of the ducts with sporicidal solution at regular intervals.

    Full Text Available Introduction: Peritonitis is the most frequent complication of peritoneal dialysis. It is the main cause of failure of the method and inclusion of patients in hemodialysis Purpose: The purpose of this study is to explore the risk factors of peritoneal dialysis peritonitis as well as the acute and long-term effects of peritonitis on peritoneal membrane function and success of the method. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during the period 1986 -2012.Results: Lack of patient compliance with the peritoneal changes protocol, lack of social support, systemic diseases and connection systems are risk factors of peritonitis. Peritonitis causes transient increase of peritoneum permeability, loss of the ability of the peritoneum for ultrafiltration and, consequently, overhydration. Long-term, recurrent episodes of peritonitis resulting in permanent loss of peritoneum capacity for ultrafiltration even fibrosis that leads to failure of the method. Finally, its effect on the reduction of the residual renal function seems to be remarkable. Conclusions: Peritonitis is the most common infectious complication of peritoneal dialysis and the main cause of morbidity associated with the method. Moreover, it is the major cause of failure of the method and patients accession in hemodialysis. Any attempt to prevent peritonitis passes through the careful patient selection and effective patient education on compliance with the rules of asepsis during peritoneal changes.

    Full Text Available Background: Hydrocephalus is a frequent central nervous system disorder in children, and despite its importance, it has not been sufficiently studied in developing countries. Patients and Methods: A prospective and descriptive study on 35 cases of infantile hydrocephalus was carried out in the neurosurgery unit of the Yaounde Central Hospital, from March 2008 to January 2010. Results: The mean age of the patients was 6.69΁1.58 months, and the majority of them were in the 0-6 months age group (71.43%. The most frequent causes were congenital malformations, with stenosis of the aqueduct of Sylvius being the most represented (31.43%. As radiological workup, a CT scan was done in more than half of the cases (57.15%, and ventriculo-peritoneal shunting was the main surgical method of management used (94.29%. Infectious complications were observed in 22.86% of our cases. Conclusion: Hydrocephalus is a frequent disorder in this Cameroonian setting affecting mostly the 0-6months age group. For early diagnosis to be made, the head circumference of neonates should be routinely measured in the labour room and followed-up in all medical visits. To avert complications following surgery, rigorous surgical procedures with effective asepsis and appropriate methods and materials for shunting should be used.

    Full Text Available Purpose: A prospective study of incisional surgical site infection in abdominal surgeries was conducted to find out incidence, common predisposing factors and microbiological profile. METHODS: 375 patients who underwent abdominal surgeries were studied in a span of 1 year. They were divided into two groups – group 1 – 316 cases who did not develop Surgical Site Infection (SSI, the 2nd group – 59 cases that developed SSI. These patients were studied by interviewing and examination according to a set proforma. The results were statistically analyzed by comparing averages using Chi square chart for finding significance of difference where applicable. RESULT: The overall SSI incidence was 15.7 % (59/375. In elective surgeries, the SSI rate was 5.7% and in emergency surgeries, it was 28.6%. It was found that SSI increased with increasing age linearly. Other significant factors involved were increasing class of wound (dirty > clean wound class, increased preoperative stay, presence of remote site infection, increased duration of surgery and use of drains. E. coli was found to be the most common organism causing SSI in abdominal operations. CONCLUSION: SSI can be reduced by decreasing the preoperative hospital stay, appropriate antibiotic administration policies, preoperative control of remote site infections, adequate preoperative patient preparation, reducing the duration of surgery to minimum, judicious use of drains and intraoperative maintenance of asepsis and following operation theatre discipline properly.

    In order to enhance the resistance to the pitting corrosion due to asepsis processes and to avoid structural fractures in dentistry drills, a plasma immersion ion implantation (PIII) treatment using nitrogen has been performed. The selected drill samples, made of AISI 434 based stainless steel with a 0.670 mm diameter, were treated at a -1kV bias between 350 C and 450 C, this temperature being controlled by both a 20-50 {mu}s pulse width and a 200-1000 Hz repetition rate in the bias. The drills were analysed by cyclic potentiodynamic tests showing a good pitting corrosion resistance when treated at around 400 C, as follows from a resulting very low hysteresis loop. Yet, the resistance appears somehow diminished by the presence of sputtering when processed at temperatures near 450 C. It is also found that the PIII nitriding effectiveness appears to be limited by the appearance of uniform corrosion. Finally, X-ray diffraction of the samples has revealed the presence of two new phases, namely {epsilon}-Fe{sub 2}N and Fe{sub 4.4}N, while scanning electron microscopy of the treated surfaces has suggested a sputtering enhancement at the highest temperatures.

    Full Text Available Background. Needleless connectors (NC are used on virtually all intravascular devices, providing an easy access point for infusion connection. Colonization of NC is considered the cause of 50% of postinsertion catheter-related infections. Breaks in aseptic technique, from failure to disinfect, result in contamination and subsequent biofilm formation within NC and catheters increasing the potential for infection of central and peripheral catheters. Methods. This systematic review evaluated 140 studies and 34 abstracts on NC disinfection practices, the impact of hub contamination on infection, and measures of education and compliance. Results. The greatest risk for contamination of the catheter after insertion is the NC with 33–45% contaminated, and compliance with disinfection as low as 10%. The optimal technique or disinfection time has not been identified, although scrubbing with 70% alcohol for 5–60 seconds is recommended. Studies have reported statistically significant results in infection reduction when passive alcohol disinfection caps are used (48–86% reduction. Clinical Implications. It is critical for healthcare facilities and clinicians to take responsibility for compliance with basic principles of asepsis compliance, to involve frontline staff in strategies, to facilitate education that promotes understanding of the consequences of failure, and to comply with the standard of care for hub disinfection.

    Full Text Available Introduction. Pacemakers are devices that modern medicine and cardiology cannot be imagined without. The technique of implantation comes to surgical procedure where all principles of asepsis and antisepsis have to be respected. Although some complications do happen, they are rather rare. Results. After the implantation of the device, the patient is not handicapped (unless the heart was additionally damaged. On the contrary, the patient returns to his work and functions normally within his family in most of the cases. The first medical appointment is scheduled a month after the implantation and the following are three and six months after. Types of devices. Today there are „new types of electrostimulation”- implantable cardioverter defibrillators and multisite electrostimulators. The former is implanted in patients at high risk of sudden cardiac death and the latter in patients with heart failure and left bundle branch block. Owing to these devices, the sudden cardiac death can be prevented successfully and the quality of a patient’s life is improved.

    Abstract Objective: this study analyzed the influence of scenario-based skills training on students' learning skills. Method: the author evaluated the nursing skills laboratory exam papers of 605 sophomores in nursing programs for seven years. The study determined the common mistakes of students and the laboratory work was designed in a scenario-based format. The effectiveness of this method was evaluated by assessing the number of errors the students committed and their achievement scores in laboratory examinations. This study presents the students' common mistakes in intramuscular and subcutaneous injection and their development of intravenous access skills, included in the nursing skills laboratory examination. Results: an analysis of the students' most common mistakes revealed that the most common was not following the principles of asepsis for all three skills (intramuscular, subcutaneous injection, intravenous access) in the first year of the scenario-based training. The students' exam achievement scores increased gradually, except in the fall semester of the academic year 2009-2010. The study found that the scenario-based skills training reduced students' common mistakes in examinations and enhanced their performance on exams. Conclusion: this method received a positive response from both students and instructors. The scenario-based training is available for use in addition to other skills training methods. PMID:27508922

    Full Text Available Fungi are organisms that can be found dispersed in the environment and in the atmospheric air. They interact with humans, animals and plants, and they may represent risks to human health.Therefore, this study aimed to identify and isolate airborne fungi in a private hospital in the municipality of Sinop, MT, from adult and neonatal intensive care units, surgery center and their doorknobs and phones. The study was carried out in May 2014, after asepsis of the sectors chosen. For the collection of fungi in the air, 75 Petri dishes (25 for each sector containing Sabouraud agar with chloramphenicol were exposed for 10 minutes. We collected samples of doorknobs and phones using swabs. The samples were stored in test tubes containing a 0.1% saline solution and then spread on plates with PDA medium supplemented with penicillin.The plates were incubated for 7 days at 25°C.The identification of airborne fungi was based on the association of macroscopic and microscopic characteristics of primary cultures. We identified 18 genera of filamentous fungi, and the highest colonization rates were found in the doorknobs and phones. The airborne fungi found in the evaluated sectors should be a warning to the hospital users, since these individuals can be considered the main disseminators of these fungi in hospital environments.

    For the last two years we have applied continuous dual-wavelength Nd:YAG 20 - 60 W power laser to various urologic operations. Transmission of laser irradiation via a flexible quartz fiber permitted operating at any depth of the wound. High-intensity irradiation of 1.06 mkm wavelength was effective in making thin incisions into a variety of tissues, including skin, subcutaneous fat, aponeurosis, muscles, urinary bladder wall, prostate gland, renal pelvis, renal capsule and parenchyma, and urethra. The incisions were especially effective if the contact method was used. Operational access was accomplished in 3 - 5 minutes. At the same time, hemostasis occurred in small diameter vessels. More reliable hemostasis could be achieved by means of 1.32 mkm wavelength. With the present laser device, we carried out 57 different urologic operations in our clinic. Examples of such operations include prostatectomy, pyelolithotomy, ureterolithotomy, nephrectomy, resection of renal cysts, condylomata acuminata of the urogenital organs, and papilloma of the urethra and bladder. The results suggest that a combination of these two wavelengths may prove most effective. Advantages of this approach include a decreased blood loss and decreased surgical time, asepsis, good short- and long-term results, and no complications.

    2008-09-01

    We present results on the analysis of 100 mL medium samples extracted from sterilized foam (Smithers-Oasis, Kent OH) used to support the growth of a representative dicotyledon ( Haplopappus gracilis) and a representative monocotyledon ( Hemerocallis cv Autumn Blaze) in NASA's Plant Growth Unit (PGU) during a 5-day Space Shuttle flight and ground experiments. At recovery, the media remaining within replicate ( n = 5) foam blocks (for both the spaceflight and ground experiments) were extracted under vacuum, filtered and subjected to elemental analyses. A unique aspect of this experiment was that all plants were either aseptically-generated tissue culture propagated plantlets or aseptic seedling clones. The design of the PGU facilitated the maintenance of asepsis throughout the mission (confirmed by post-flight microbial sampling) and thus any possible impact of microorganisms on medium composition was eliminated. Concentration levels of some elements remained the same, while some decreased and others increased. There was a significant two-fold difference between the final concentrations of potassium when the Earth-based and microgravity experiments were contrasted.

    Full Text Available Introduction: Tetanus is a serious infectious disease and the most common cause of neonatal mortality in developing countries. Although neonatal tetanus (NT can be prevented by immunization of expectant mothers, good hygiene and asepsis during delivery, total eradication of organism is not possible. Methods: The cross-sectional study was done on 480 pregnant women after delivery. Data was collected by a questionnaire and analysed using SPSS windows software program. Results: Prenatal immunization rate (complete and partial was 65/2% and 34/8%, respectively. There was a significant relationship between the vaccination status and age, education of mother, parity and length of time between pregnancy and previous pregnancy. The reasons reported by non immunized mothers (not receiving the two dose vaccine included complete tetanus vaccination coverage before pregnancy, lack of awareness about the needs for vaccination, improper counseling by persons responsible for antenatal care, e.t.c. Conclusion: Considering the results of the study, it is proposed that a complete history of the pregnant woman recorded at the first antenatal visit should be the basis of counseling and education of the woman and prenatal care staff should be also be fully educated.

    Full Text Available Abstract: Chronic cutaneous lesions affect 15% of diabetic human patients and represent a risk 15 to 46 times larger of limb amputations compared to people with normal glycemia. It is assumed that half of these amputations could be prevented by early treatment of wounds, for example, with proper cell therapy. Objectives: In this study, the action of the autologous transplant of mesenchymal stem-cells (MSC was evaluated compared to the treatment with autologous platelet rich plasma (PRP in the cicatrization of cutaneous lesions induced in diabetic mice. These animals were previously treated with streptozootocin to induce diabetes mellitus and round wounds of 1.5cm in diameter were created in the posterior region. Diameters of the wounds and healing time were evaluated during 30 days and the results were submitted to variance analysis and Tukey's test average. It was noticed that the animals treated with MSC presented a more accelerated cicatrization of the cutaneous lesion than the animals treated with PRP. However, the treatment with PRP presented better results than just the daily asepsis of the lesions with saline or covering them with semi-permeable bandage. Besides, the use of semi-permeable bandage kept the cutaneous lesions of diabetic mice did not interfere negatively with cicatrization, proved to be harmless to use, but kept the cutaneous lesions more hydrated than the ones exposed to the environment.

    Full Text Available Hepatitis C virus (HCV and hepatitis B virus (HBV are major causes for liver disease worldwide and potential causes for substantial morbidity and mortality in the future. The aim of this study was to assess the prevalence of hepatitis C and B virus infection and to identify the associated risk factors of viral hepatitis. In our experiments we use as materials 107 patients, 48 men and 59 women, aged from 7 to 67 years old. The maximum incidence of HBV and HCV hepatitis was observed at patients aged between 40 to 60 and especially at people in urban areas. The number of cases with HCV was twice higher at men than at women, while for HVB the incidence was higher for men than for women. Risk factors for transmission of HCV and HBV were medical procedure in the high-risk group, while vertical or sexual transmission belongs to the low-risk patient group. In conclusion, this study demonstrates that the prevalence of HBV and HCV infection is high, thus asepsis and antisepsis measures should be strictly followed.

    It is not unusual for a specialist or general practitioner to be presented with a pathology which necessitates the use of an intra-articular injection of corticosteroids, hyaluronic acid or a local anaesthetic. It would seem to be interesting to update and to precise the techniques and methods of intraarticular injections which have appeared in recent international publications, when we know that 30 % of the injections given into the knee and so called "dry" are incorrect and, therefore, inefficient. The indication of an articular injection depends, firstly, on the diagnosis which should be done with great care; after which should be an objective analysis complete with secondary effects linked to both the injection and the product used. The conditions of asepsis, the choice of needles and quantities of the injection and even the ways of the injections should be reviewed in detail. The last studies clearly question the secondary effects of the cartilage degradations of the cortisone given as an intra-articular injection and shows its efficiency on the pain and inflammatory phenomonen in osteoarthritis. Studies on hyaluronic acid are often contradictory going from a modest result to an important pain relief but it is necessary to be aware that the objective criteria are difficult to interpret. The use of local anaesthetics in intra-articular is limited by the few indications in view of the major risk of aggravating the pre-existing lesions by the disappearing signs of pain.

    Aseptic technique includes the use of sterile surgical gloves for survival surgeries in rodents to minimize the incidence of infections. Exam gloves are much less expensive than are surgical gloves and may represent a cost-effective, readily available option for use in rodent surgery. This study examined the effectiveness of surface disinfection of exam gloves with 70% isopropyl alcohol or a solution of hydrogen peroxide and peracetic acid (HP-PA) in reducing bacterial contamination. Performance levels for asepsis were met when gloves were negative for bacterial contamination after surface disinfection and sham 'exertion' activity. According to these criteria, 94% of HP-PA-disinfected gloves passed, compared with 47% of alcohol-disinfected gloves. In addition, the effect of autoclaving on the integrity of exam gloves was examined, given that autoclaving is another readily available option for aseptic preparation. Performance criteria for glove integrity after autoclaving consisted of: the ability to don the gloves followed by successful simulation of wound closure and completion of stretch tests without tearing or observable defects. Using this criteria, 98% of autoclaved nitrile exam gloves and 76% of autoclaved latex exam gloves met performance expectations compared with the performance of standard surgical gloves (88% nitrile, 100% latex). The results of this study support the use of HP-PA-disinfected latex and nitrile exam gloves or autoclaved nitrile exam gloves as viable cost-effective alternatives to sterile surgical gloves for rodent surgeries.

    Full Text Available Background: The health-care professionals, particularly paramedics are exposed to bloodborne infections during medical rescue operations. The aim of this study was to assess knowledge of bloodborne infections, their prevention and interrupted routes of infection transmission among paramedics. Materials and Methods: The study comprised 220 paramedics employed in emergency departments and ambulance services. Material was collected using an anonymus questionnaire, developed for the purpose of this study. Results: As many as 80% of the surveyed people reported frequent contact with patients' blood; 65% of the paramedics before establishing the intravenous access palpates the conduct of the vein; 81% introduce peripheral venous catheter directly after disinfection of the skin; and 98% apply personal protection measures. Conclusions: The analysis of knowledge of asepsis and antisepsis of bloodborne infections among paramedics points to a series of shortcomings in their adequate preparation to reduce the effects of exposure to infectious material. However, it should be emphasized that people with higher education presented a higher level of knowledge than those with postsecondary vocational education. In the opinion of the study group mandatory training in the discussed area would prove to be the most effective method for reducing the number of bloodborne infections. Med Pr 2013;64(2:239–243

    Cabello, Felipe

    2015-06-01

    Realism is a painting style that began with Millet and Courbet in politically convulsed France in the middle of the nineteenth century. In the second half of that century, the pragmatic and democratic tradition of the United States fostered the careers of many realist painters, including that of Thomas Eakins. Eakins, trained in France, developed his career completely associated with Philadelphia at a time when this city was in the vanguard of American emerging industry, culture and medicine. Eakins "The clinic of Dr. Gross" and the "The clinic of Dr. Agnew" are icons of these developments and symbolize a perfect union of art and medicine. Both paintings permit the viewer to appreciate the artist's mastery, originality and Americanism while simultaneously tracking the progress of surgery as evidenced by the introduction of asepsis, anesthesia and nursing. Eakins mastery is revealed by its use of some European Old Masters approaches to portray medical professionals undertaking their daily duties in their work environments with critical and unadorned vision. This combination of vision and skills led Eakins to create a highly original yet analytical art. Unfortunately, his representations were far ahead of his time and resulted in under appreciation of his paintings and a censorious reaction to their content. His contemporaries rejection of Eakins work negatively affected his career as a painter, as a teacher and even his private life. This judgment was overturned in subsequent years and by the twentieth century Eakins was recognized as an American master without parallel.

    Delivery room infections are frequent, and many of them could be avoided through higher standards of care. The authors examine this issue by comparing it to English and French reality. Unlike England, in Italy and France the relationship established between health facility, physician and patient is outlined in a contract. In England, the judges' decisions converge toward a better and higher protection of the patient-the actor-and facilitate the probative task. In case of infections, including those occurring in the delivery room, three issues are evaluated: the hospital's negligent conduct, damages if any and causal nexus. Therefore, the hospital must demonstrate to have taken the appropriate asepsis measures according to current scientific knowledge concerning not only treatment, but also diagnosis, previous activities, surgery and post-surgery. In order to avoid a negative sentence, both physicians and hospital have to demonstrate their correct behavior and that the infection was caused by an unforeseeable event. The authors examine the most significant rulings by the Courts and the Supreme Court. They show that hospitals can avoid being accused of negligence and recklessness only if they can demonstrate to have implemented all the preventive measures provided for in the guidelines or protocols.

    The Utrechtsch Geneeskundig Gezelschap [Utrecht Medical Society] Matthias van Geuns (1793 to the present) is the oldest still active local medical society in the Netherlands. Membership is select and limited to only one local representative from every medical specialty. Proceedings of the medical meetings have never been published, neither was a prize offered for a best essay. The minutes of the meetings, however, have been preserved. They give a fascinating insight into the way this small society reacted to the developments in medicine during two centuries. Infectious diseases, for example cholera, abdominal typhus and tuberculosis, and newly introduced surgical procedures like anaesthesia and antisepsis or asepsis were discussed. The lectures had to be attended by all members and were meant to be aimed at a general medical audience. The society members were expected to prepare themselves and take part in the discussion afterwards, everyone from his own point of view. This procedure was both instructive and stimulating. The minutes of the Utrechtsch Geneeskundig Gezelschap Matthias van Geuns are a valuable source for scientific research on medical developments in the Netherlands, particularly in Utrecht.

  6. Commercial considerations in tissue engineering.

    2006-10-01

    Tissue engineering is a field with immense promise. Using the example of an early tissue-engineered skin implant, Dermagraft, factors involved in the successful commercial development of devices of this type are explored. Tissue engineering has to strike a balance between tissue culture, which is a resource-intensive activity, and business considerations that are concerned with minimizing cost and maximizing customer convenience. Bioreactor design takes place in a highly regulated environment, so factors to be incorporated into the concept include not only tissue culture considerations but also matters related to asepsis, scaleup, automation and ease of use by the final customer. Dermagraft is an allogeneic tissue. Stasis preservation, in this case cryopreservation, is essential in allogeneic tissue engineering, allowing sterility testing, inventory control and, in the case of Dermagraft, a cellular stress that may be important for hormesis following implantation. Although the use of allogeneic cells provides advantages in manufacturing under suitable conditions, it raises the spectre of immunological rejection. Such rejection has not been experienced with Dermagraft. Possible reasons for this and the vision of further application of allogeneic tissues are important considerations in future tissue-engineered cellular devices. This review illustrates approaches that indicate some of the criteria that may provide a basis for further developments. Marketing is a further requirement for success, which entails understanding of the mechanism of action of the procedure, and is illustrated for Dermagraft. The success of a tissue-engineered product is dependent on many interacting operations, some discussed here, each of which must be performed simultaneously and well.

A secondary objective was to assess the incidence of surgical site infection (SSI).Methods Patients undergoing modified radical mastectomy were randomly assigned to coated VICRYL* Plus antibacterial (Polyglactin 910) suture or Chinese silk suture. Cosmetic outcomes were evaluated postoperatively at days 12 (±2) and 30 (±5), and the evidence of SSI was assessed at days 3, 5, 7, 12 (±2), 30 (±5), and 90 (±7). Cosmetic outcomes were independently assessed via visual analogue scale (VAS) score evaluations of blinded incision photographs (primary endpoint) and surgeon-assessed modified Hollander Scale (mHCS) scores (secondary endpoint).SSI assessments used both CDC criteria and ASEPSIS scores.Results Six Chinese hospitals randomized 101 women undergoing modified radical mastectomy to closure with coated VICRYL* Plus suture (n=51) or Chinese silk suture (n=50). Mean VAS cosmetic outcome scores for antibacterial suture (67.2) were better than for Chinese silk (45.4) at day 30 (P<0.0001)). Mean mHCS cosmetic outcome total scores, were also higher for antibacterial suture (5.7) than for Chinese silk (5.0) at day 30 (P=0.002).Conclusions Patients using coated VICRYL* Plus suture had significantly better cosmetic outcomes than those with Chinese silk sutures. Patients using coated VICRYL* Plus suture had a lower SSI incidence compared to the Chinese silk sutures, although the difference did not reach statistical significance.

    Full Text Available Background: In hair transplantation, the survival rate of harvested grafts depends upon many factors like maintenance of hydration, cold temperature, reduced mechanical handling and asepsis. All these factors are favourably improved if time out of body is reduced significantly. We have tried a modification called direct hair transplantation in the existing follicular unit extraction technique, in which the follicular unit grafts are implanted as soon as they are harvested. In this article, we have described the detailed methodology and a series of 29 patients who underwent direct hair transplantation. Aim: To evaluate the efficacy and feasibility of direct hair transplantation. Subjects and Methods: The patients willing to undergo hair transplantation by the technique of follicular unit extraction were enrolled for the surgery. After administration of local anaesthesia, the recipient sites were created. Thereafter, the processes of scoring the skin with a motorized punch, graft extraction and implantation were performed simultaneously. These patients were followed up to look for the time period of initiation of hair growth, the growth achieved at the end of 6-8 months and any adverse events. The results of patients with noticeable improvement in the photographs and reduction in baldness grade were taken as ′good′, whereas, in other patients, it was classified as ′poor′. Results: All patients were males with age ranging from 21 to 66 years (median 30 years. Twenty-six patients had androgenetic alopecia, 1 patient had traction alopecia and 2 patients had scarring alopecia. Twenty-seven patients showed ′good′ results, whereas 2 patients showed ′poor′ results. Conclusion: Direct hair transplantation is a simple and feasible modification in the follicular unit extraction technique. It is an efficacious surgical treatment modality for baldness.

  11. History of parenteral nutrition.

    The concept of feeding patients entirely parenterally by injecting nutrient substances or fluids intravenously was advocated and attempted long before the successful practical development of total parenteral nutrition (TPN) four decades ago. Realization of this 400 year old seemingly fanciful dream initially required centuries of fundamental investigation coupled with basic technological advances and judicious clinical applications. Most clinicians in the 1950's were aware of the negative impact of starvation on morbidity, mortality, and outcomes, but only few understood the necessity for providing adequate nutritional support to malnourished patients if optimal clinical results were to be achieved. The prevailing dogma in the 1960's was that, "Feeding entirely by vein is impossible; even if it were possible, it would be impractical; and even if it were practical, it would be unaffordable." Major challenges to the development of TPN included: (1) formulate complete parenteral nutrient solutions (did not exist), (2) concentrate substrate components to 5-6 times isotonicity without precipitation (not easily done), (3) demonstrate utility and safety of long-term central venous catheterization (not looked upon with favor by the medical hierarchy), (4) demonstrate efficacy and safety of long-term infusion of hypertonic nutrient solutions (contrary to clinical practices at the time), (5) maintain asepsis and antisepsis throughout solution preparation and delivery (required a major culture change), and (6) anticipate, avoid, and correct metabolic imbalances or derangements (a monumental challenge and undertaking). This presentation recounts approaches to, and solution of, some of the daunting problems as really occurred in a comprehensive, concise and candid history of parenteral nutrition.

    Full Text Available Abstract Introduction Since the 1980s, leeches have been ingeniously used in the management of venous flap congestion. The presence of anticoagulative substances in their saliva improves the blood drainage. Their digestive tract contains several bacterial species, the main ones being Aeromonas hydrophila and Aeromonas veronii biovar sobria, which contribute to the digestion of ingested blood. These bacteria can be the cause of infections. Case presentation We report two cases of septicemia related to Aeromonas veronii biovar sobria that presented after leeches had been applied to congested transverse rectus abdominis myocutaneous flaps for delayed mammary reconstructions. Patient number 1 was a 55-year-old Caucasian woman who underwent a delayed breast reconstruction procedure. On the sixth postoperative day she showed a clinical presentation of septicemia. Aeromonas veronii biovar sobria was identified in the patient’s skin and blood bacteriological samples. Her fever ceased after 4 days of antibiotic treatment. Patient number 2 was a 56-year-old Caucasian woman who underwent a delayed breast reconstruction procedure. On the seventh postoperative day we noticed that she showed a clinical presentation of septicemia. Aeromonas veronii biovar sobria was identified in the patient’s blood cultures and local bacteriological samples. An antibiogram showed resistance to amoxicillin/clavulanic acid. Her fever ceased on the eleventh postoperative day after 4 days of antibiotic treatment. Conclusion The rate of infection after application of leeches is not negligible. The concentration of Aeromonas inside the digestive tracts of leeches largely decreases when the patient is under antibiotic therapy. These germs are sensitive to third-generation cephalosporins and fluoroquinolones and resistant to amoxicillin/clavulanic acid. We recommend preventive treatment based on classical measures of asepsis and on oral antibioprophylaxy with a fluoroquinolone

    Currently, English scientific literature is lacking in studies showing that medical assistance may be delivered without errors. Since two years ago, the department of nephrology and urology of ASL BA has been establishing a process of clinical risk management.Starting with the reporting of a single error, a related database was subsequently developed, in order to validate technical and organizational procedures that would be of common use in the daily clinical practice.With regard to error reporting, the system of incident reporting was adopted: that is a structured collection of significant events for the safety of patients with a specific form for reporting to be filled out by health professionals. Reports have been collected, coded and analysed. Finally measures were adopted to reduce the recurrence of the error.This first phase consisted on writing the procedures in order to create structured diagnostic-therapeutic protocols. In 18 months of observation adopting the incident reporting form, 48 errors have been reported: 52% due to adverse events; 12.5% to adverse reactions; 31.2% near misses and 2% to sentinel events. In 35.4 % of cases the error occurred in the administration or prescription of drug therapies, in 18.7% of cases it occurred in the organizational stage, in 12.5% it was a surgical error, in 18.7% of cases the error was due to incorrect asepsis, in 8.3% of cases it occurred during the medical examination and finally in 8.3% during dialysis. An analysis of the error database resulted in the choice of more urgent procedures. It is our view that only the observation of procedures can ensure the achievement of a high quality with improved clinical outcomes, reduction of complications, elimination of inappropriate interventions and increased patient satisfaction.

    Full Text Available OBJECTIVE: The presence of Candida albicans on the surfaces of denture-base acrylic resins is strongly related to the development of oral stomatitis. This study evaluated the antifungal action of different agents over microwave-cured acrylic resin without polishing specimens previously contaminated with Candida albicans. MATERIAL AND METHODS: Sixty specimens were immersed in BHI broth previously inoculated with the yeast and stored for 3 h at 37ºC. They were divided into 5 experimental groups (n=10: G1: 2% chlorhexidine solution (10 min; G2: 0.5% sodium hypochlorite (10 min; G3: modified sodium hypochlorite (10 min; G4: effervescent agent (5 min; G5: hydrogen peroxide 10v (30 min. The specimens of the control group 1 (C1 were not disinfected. Ten additional specimens of the control group 2 (C2 were not infected with the yeast, aiming to check the asepsis during the experiment. The disinfection agents were neutralized and the acrylic resin specimens were immersed in BHI Broth for 24 h. Culture media turbidity was evaluated spectrophotometrically according to the transmittance degree, i.e. the higher the transmittance the stronger the antimicrobial action. Statistical analysis was performed (Kruskal-Wallis Test, p<0.05. RESULTS: The results, represented by the medians, were: G1 = 40; G2 = 100; G3 = 100; G4 = 90; G5 = 100; C1 = 40; C2 = 100. CONCLUSIONS: This in vitro study suggested that sodium hypochlorite-based substances and hydrogen peroxide are more efficient disinfectants against C. albicans than 2% chlorhexidine solution and the effervescent agent.

    Full Text Available Background: Hepatitis B is a disease of public health importance in Iran. We conducted this study to determine the epidemiology, clinical presentations of hepatitis B infection in Khuzestan province, Southwest of Iran.Methods: A cross-sectional study was conducted on hepatitis B virus (HBV positive individuals referred to the Ahwaz Jondishapour University Hospitals (AJSUH and Hepatitis Clinic from February 2002 to May 2007. Based on a specially-designed protocol, standard commercially-available tests and physical examinations were performed. All subjects were evaluated using a face-to-face questionnaire about demographic aspects. The analysis included data on past medical history, physical examination and periodic evaluation clinically and serologically.Results: 1264 patients infected with hepatitis B virus participated in the study. The patients consisted of 874 male and 390 female patients with the age range of 8-72 years. The most frequent age group was 20-40 years (56.4%. Anti-delta antibodies were observed in 4.7% of the carriers (59⁄1264, anti hepatitis C virus (anti-HCV antibodies in 0.9% (12⁄1095 and anti human immunodeficiency virus (anti-HIV antibodies in 0.1% (1⁄1095 of active carriers, respectively. Of 1264 patients infected with hepatitis B virus, 71 (5.6% were also hepatitis B e antigen (HBeAg positive, no difference in female to male ratio was observed between HBeAg-positive and HBeAg-negative patients with chronic hepatitis B.Conclusions: The family history of hepatitis, dental procedures and a history of transfusion are important risk factors for HBV infection in our area. More careful screening and preventive measures, strict attention to asepsis, evaluation of risk factors, and improvements in certain lifestyle patterns and customs in this area may be essential to prevent transmission of the infection.

    Marcelo Vial Roehe

    2006-08-01

    Full Text Available Partindo da analítica existencial do filósofo Martin Heidegger, o artigo propõe que o conhecimento é um correlato ontológico do modo de ser humano e que a tradição científica comete um erro ontológico quando, por meio de uma suposta assepsia metodológica, separa o conhecedor do conhecido. Sendo assim, argumenta-se que qualquer empreendimento científico está vinculado às características do ser humano, que qualquer que seja o foco de uma investigação científica, este já estará sempre submetido às possibilidades perspectivas humanas. Portanto, a objetividade que a tradição científica preconiza, de modo algum se realiza. Propõe-se também que a psicologia não necessita adotar o modelo naturalista tradicional, a fim de adquirir credibilidade científica.Based on German philosopher Martin Heidegger's existential analytic, this article proposes that knowledge is an ontological counterpart to man's mode of being, and the scientific tradition incurs in ontological error when, through the use of a so-called methodological asepsis, it separates who-knows (the "subject" of knowledge from what-is-known (the "object" of knowledge. Thus, it can be argued that any scientific enterprise is linked to the characteristics of human beings, and whatever focus a scientific investigation might have, this focus will always be limited by human perceptive capabilities and, therefore, the objectivity proclaimed by the scientific tradition is never achieved at all. The article also proposes that psychology does not need to adopt the traditional naturalistic model in order to achieve scientific credibility.

    Infection is a potentially serious complication of epidural analgesia and with an increase in its use in wards there is a necessity to demonstrate its safety. We aimed to compare the incidence of colonization of epidural catheters retained for short duration (for 48 h) postoperative analgesia in postanesthesia care unit and wards. It was a prospective observational study done in a tertiary care teaching public hospital over a period of 2 years and included 400 patients with 200 each belonged to two groups PACU and ward. We also studied epidural tip culture pattern, skin swab culture at the entry point of the catheter, their relation to each other and whether colonization is equivalent to infection. Data were analyzed using statistical software GraphPad. Overall positive tip culture was 6% (24), of them 7% (14) were from PACU and 5% (10) were from ward (P = 0.5285). Positive skin swab culture was 38% (150), of them 20% (80) were from PACU and 18% (70) were from ward (P = 0.3526). The relation between positive tip culture and positive skin swab culture in same patients is extremely significant showing a strong linear relationship (95% confidence interval = 0.1053–0.2289). The most common microorganism isolated was Staphylococcus epidermidis. No patient had signs of local or epidural infection. There is no difference in the incidence of epidural catheter tip culture and skin swab culture of patients from the general ward and PACU. Epidural analgesia can be administered safely for 48 h in general wards without added risk of infection. The presence of positive tip culture is not a predictor of epidural space infection, and colonization is not equivalent to infection; hence, routine culture is not needed. Bacterial migration from the skin along the epidural track is the most common mode of bacterial colonization; hence, strict asepsis is necessary. PMID:27076712

    Full Text Available Background: Percutaneous aspiration of abscesses under ultrasonography (USG and computer tomography (CT scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome. Materials and Methods: Twenty-nine patients with dorsolumbar spondylodiscitis without gross neural deficit with psoas abscess of size >5 cm were selected for PCD. It was done as a day care procedure under local anesthesia. Sequentially, aspiration followed by guide pin-guided trocar and catheter insertion was done without image guidance. Culture sensitivity was done and chemotherapy initiated and catheter kept till the drainage was <10 ml for 48 hours. Outcome assessment was done with relief of pain, successful abscess drainage and ODI (Oswestry Disability Index score at 2 years. Results: PCD was successful in all cases. Back and radicular pain improved in all cases. Average procedure time was 24.30 minutes, drain output was 234.40 ml, and the drainage duration was 7.90 days. One patient required surgical stabilisation due to progression of the spondylodiscitis resulting in instability inspite of successful drainage of abscess. Problems with the procedure were noticed in six patients. Multiple attempts ( n = 2, persistent discharge ( n = 1 for 2 weeks, blocked catheter ( n = 2 and catheter pull out ( n = 1 occurred with no effect on the outcome. The average ODI score improved from 62.47 to 5.51 at 2 years. Conclusions: Clinically guided PCD is an efficient, safe and easy procedure in drainage of psoas abscess.

    针刀治疗的实质是经皮微创软组织松解术.传统针灸学当中具备经皮微创软组织松解术,但在近现代逐渐被边缘化,因此针刀医学的发展是对针灸学的复古.与传统针灸学相比,针刀医学对经筋学说进行了现代解释,吸收了解剖学和病理学理论以及无菌和麻醉技术,并对传统针具进行了改进,因此钎刀医学又是对针灸学的创新.同时针刀医学的发展弥补了针灸学研究的不足,将在客观上促进针灸学的学科分化和学科交叉,是针灸学发展新的增长点.%Acupotomology is a technique of percutaneous minimally invasive soft tissue releasing. It can be found in traditional acupuncture, but is deemphasized in modern times. Therefore, the development of acupotomology is held as restoring of ancient ways of acupuncture. Compared with traditional acupuncture, acupotomology makes modern interpretations on the theory of muscle regions, absorbs theories of anatomy and pathology as well as techniques of asepsis and anaesthesia. It improves traditional needling tool. Therefore, it is also held as an innovation of acupuncture. The development of acupotomology makes up for the deficiency of acupuncture study. It will promote the differentiation and crossing of acupuncture discipline, and become a new trend of acupuncture.

    Full Text Available Introduction: Cross-contamination and cross-infection can occur by direct contact with micro-organisms, indirect contact with contaminated objects, droplet transmission, and inhalation of airborne pathogens. In dentistry, operatory surfaces can routinely become contaminated with patient saliva, blood, and other fluids during treatment. Aims and Objectives: This review is aimed to identify cross-contamination and spread of infection by various means and the appropriate preventive measures to be implemented. This review will also highlight the various aspects that are neglected in various dental schools/dental practice or any dental set up that potentiate cross-contamination ultimately affecting the dentist, dental team and the patients. Materials and Methods: A review of the dental literature concerning cross-contamination was performed. Material appearing in the literature before 1996 was reviewed as exhaustively as possible and materials after 1996 were reviewed electronically. In Medline, key words like cross-contamination, sterilization, asepsis, infection, infection control, prevention were used in various combinations to obtain a potential reference for review. A total of 2245 English Language titles were found, many were repeated due to recurring searches. The headings were shortlisted and reviewed for detailed examination. Results: A comprehensive review to evaluate the methods of preventing cross-contamination in dentistry involving various aspects and challenges encountered in a dental set up was constructed which was missing in the references of the review. Conclusions: Awareness and the necessary precautions play a pivotal role in preventing the occurrence of cross-contamination. It is the responsibility of the entire dental team to work in unison to prevent the menace of cross-contamination and spread of infection.

    Despite endophthalmitis being the most feared complication, antibioprophylaxis remains controversial in intravitreal injections. Therefore, we conducted a systematic review and meta-analysis on the effects of antibioprophylaxis in intravitreal injections in the prevention of endophthalmitis. The PubMed, Cochrane Library, Embase and Science Direct databases were searched for studies comparing groups with and without antibiotics in intravitreal injection, with the use of the following keywords: "antibiotic*", "endophthalmitis" and “intravitreal injection*”. To be included, studies needed to specify number of participants and number of endophthalmitis within each group (with and without antibiotics). We conducted meta-analysis on the prevalence of clinical endophthalmitis including both culture-proven and culture negative samples. Nine studies were included. A total of 88 incidences of endophthalmitis were reported from 174,159 injections (0.051% i.e., one incidence of endophthalmitis for 1979 injections). Specifically, 59 incidences of endophthalmitis were reported from 113,530 injections in the group with antibiotics (0.052% or one incidence of endophthalmitis for 1924 injections) and 29 incidences of endophthalmitis from 60,633 injections in the group without antibiotics (0.048% or one endophthalmitis for 2091 injections). Our meta-analysis did not report a significant difference in the prevalence of clinical endophthalimitis between the two groups with and without topical antibiotics: the odds ratio of clinical endophthalimitis was 0.804 (CI95% 0.384–1.682, p = 0.56) for the antibiotic group compared with the group without antibiotics. In conclusion, we performed the first large meta-analysis demonstrating that antibioprophylaxis is not required in intravitreal injections. Strict rules of asepsis remain the only evidence-based prophylaxis of endophthalmitis. The results support initiatives to reduce the global threat of resistance to antibiotics. PMID

Specifically, 59 incidences of endophthalmitis were reported from 113,530 injections in the group with antibiotics (0.052% or one incidence of endophthalmitis for 1924 injections and 29 incidences of endophthalmitis from 60,633 injections in the group without antibiotics (0.048% or one endophthalmitis for 2091 injections. Our meta-analysis did not report a significant difference in the prevalence of clinical endophthalimitis between the two groups with and without topical antibiotics: the odds ratio of clinical endophthalimitis was 0.804 (CI95% 0.384-1.682, p = 0.56 for the antibiotic group compared with the group without antibiotics. In conclusion, we performed the first large meta-analysis demonstrating that antibioprophylaxis is not required in intravitreal injections. Strict rules of asepsis remain the only evidence-based prophylaxis of endophthalmitis. The results support initiatives to reduce the global threat of resistance to antibiotics.

    Full Text Available Abstract Background and objectives: The increased prevalence of obesity in the general population extends to women of reproductive age. The aim of this study is to report the perioperative management of a morbidly obese pregnant woman, body mass index >50 kg/m2, who underwent cesarean section under general anesthesia. Case report: Pregnant woman in labor, 35 years of age, body mass index 59.8 kg/m2. Cesarean section was indicated due to the presumed fetal macrosomia. The patient refused spinal anesthesia. She was placed in the ramp position with cushions from back to head to facilitate tracheal intubation. Another cushion was placed on top of the right gluteus to create an angle of approximately 15° to the operating table. Immediately before induction of anesthesia, asepsis was carried out and sterile surgical fields were placed. Anesthesia was induced in rapid sequence, with Sellick maneuver and administration of remifentanil, propofol, and succinilcolina. Intubation was performed using a gum elastic bougie, and anesthesia was maintained with sevoflurane and remifentanil. The interval between skin incision and fetal extraction was 21 min, with the use of a Simpson's forceps scoop to assist in the extraction. The patient gave birth to a newborn weighing 4850 g, with Apgar scores of 2 in the 1st minute (received positive pressure ventilation by mask for about 2 min and 8 in the 5th minute. The patient was extubated uneventfully. Multimodal analgesia and prophylaxis of nausea and vomiting was performed. Mother and newborn were discharged on the 4th postoperative day.

    Full Text Available Infection is a potentially serious complication of epidural analgesia and with an increase in its use in wards there is a necessity to demonstrate its safety. We aimed to compare the incidence of colonization of epidural catheters retained for short duration (for 48 h postoperative analgesia in postanesthesia care unit and wards. It was a prospective observational study done in a tertiary care teaching public hospital over a period of 2 years and included 400 patients with 200 each belonged to two groups PACU and ward. We also studied epidural tip culture pattern, skin swab culture at the entry point of the catheter, their relation to each other and whether colonization is equivalent to infection. Data were analyzed using statistical software GraphPad. Overall positive tip culture was 6% (24, of them 7% (14 were from PACU and 5% (10 were from ward (P = 0.5285. Positive skin swab culture was 38% (150, of them 20% (80 were from PACU and 18% (70 were from ward (P = 0.3526. The relation between positive tip culture and positive skin swab culture in same patients is extremely significant showing a strong linear relationship (95% confidence interval = 0.1053–0.2289. The most common microorganism isolated was Staphylococcus epidermidis. No patient had signs of local or epidural infection. There is no difference in the incidence of epidural catheter tip culture and skin swab culture of patients from the general ward and PACU. Epidural analgesia can be administered safely for 48 h in general wards without added risk of infection. The presence of positive tip culture is not a predictor of epidural space infection, and colonization is not equivalent to infection; hence, routine culture is not needed. Bacterial migration from the skin along the epidural track is the most common mode of bacterial colonization; hence, strict asepsis is necessary.

    Full Text Available Background - Ocular surface disorders due to limbal stem cell deficiency are an important cause of ocular morbidity and visual loss. Although autologous limbal stem cell transplants have helped in the management of unilateral disease, allografts in those with bilateral disease often fail due to immunological reasons. The use of autologous buccal epithelium cultivated on amniotic membrane has been described as a useful approach in the management of this condition. It is the purpose of this study to explore the feasibility of using a novel thermo-gelatin polymer (TGP as a substrate to culture these cells, and to characterize them using RNA extraction and RT-PCR. Methods - Oral cheek mucosal biopsies were obtained from 5 adult patients undergoing Modified Osteo-Odonto Keratoprosthesis surgery. The specimens were transported to the laboratory in transport medium. The cells were released using enzymatic digestion and seeded in both convention culture medium and TGP. The resulting cellular growth was characterized using RNA extraction and RT-PCR. Results - Cells could be cultured from 4 of the 5 specimens. In one specimen, contamination occurred and this was discarded. In the other specimens, the cheek epithelial cells could be cultured in both the conventional culture medium and TGP, with equal ease. RT-PCR revealed the presence of K3, a marker for epithelial cells, and GAPDH indicating the presence of some adipose tissue as well. Conclusions - It is possible to culture autologous cheek mucosal epithelial cells using TGP, a synthetic scaffold, without the need for other biological substrates. Since the specimens are obtained from the oral cavity, stringent asepsis is required. Further studies are required for histopathological characterization of the cultured cells and to create a model for delivery onto the ocular surface of eyes with bilateral surface disease due to limbal stem cell deficiency.

  14. The Boundaries of Imposture. Reflections on Ethnographic Work Among Religious Minorities

    2008-06-01

    Full Text Available The author discusses the admission of subjectivity as a task in the service of the ideal of scientific asepsis. Those who argue that the interference caused by the impact of the idiosyncratic factor on the objectivity ideal can be eliminated by techniques of confession and self —control approve of, beyond the unlikely efficiency of such measures, the acknowledgement of objectivity as the ultimate goal of anthropological practice. In the ethnography of religions, the two— way suspicion between the researchers and the researched permeates into all aspects of the inquiry; fills with uncertainties the relationships with our informants and with our colleagues; and is present in our readings, in the texts we write and in the keys with which we interpret; in sum, conditions the production of knowledge from beginning to end, and takes us to ask ourselves for the meaning of that ideal at times when the very boundaries of imposture are often at stake.

    En este texto se discute el reconocimiento de la subjetividad como tarea puesta al servicio del ideal de asepsia científica. Quienes postulan que la interferencia causada por el impacto del factor idiosincrásico sobre el ideal de objetividad puede ser conjurada mediante técnicas de confesión y autocontrol aprueban, más allá de la improbable eficacia de tales medidas, el reconocimiento de la objetividad como meta última de la actividad antropológica. En la etnografía con religiones, la sospecha de doble dirección, entre investigadores e investigados, se cuela por todas las rendijas del trabajo; impregna de incertidumbres las relaciones con nuestros informantes, con nuestros propios colegas; está presente en las lecturas que hacemos, los textos que escribimos y las claves con las que interpretamos. Condiciona, en suma, la producción de conocimiento de principio a fin, y nos lleva a preguntarnos por el sentido de aquel ideal, cuando lo que a menudo está en juego son los límites mismos

Salmonella was identified in two scald water samples but was absent in the water from chiller and in the final product, which might be explained in terms of chlorine addition and temperature reduction. The analysis revealed that MPN of Escherichia coli was in the range of O objetivo deste trabalho foi identificar a contaminação microbiana no processo de escaldagem, assepsia e resfriamento do frango (chiller, e em linguiças de frango produzidas a partir destes. As amostras foram coletadas em um frigorífico de aves, em sete datas e analisadas em triplicata. A presença de Salmonella foi detectada em duas amostras da água de escaldagem não estando mais presente na água do chiller e nem no produto final. Isto se deve à redução de temperatura da água e adição de cloro. O NMP de coliformes fecais variou entre < 1 a 11/ml na água de escaldagem e < 1 a 64/ml na água do chiller, que embora em padrões aceitáveis, mostram tendência de acréscimo no chiller, devido principalmente ao processo de evisceração. As contagens de Aeromonas variaram de 5 a 3,5x10¹UFC/ml na água de escaldagem e 9 a 3,7x10²UFC/ml na água do chiller. Este acréscimo se deve, provavelmente, por Aeromonas ser psicrófila e também devido a retirada das víceras. As análises de linguiça de frango mostraram acréscimo nas contagens de Aeromonas, apresentando até 2,5x10³UFC/g. Esta tendência de aumento de crescimento no produto final, aliado a capacidade de causar infecções de Aeromonas demonstram a necessidade de incluir a análise destas nas avaliações microbiológicas de alimentos.

Para atingir esses objetivos os institutos recrutaram os melhores cientistas disponíveis em todos os lugares. Este foi um período fulgurante para a pesquisa sublinhado por inúmeras descobertas sobre as doenças infecciosas. Passada essa fase, os institutos entraram em depressão e até mesmo insolvência. Muitos se recuperaram, alguns não. Muitos ainda sofrem de uma "crise de identidade". Neste ensaio analisamos o destino dos institutos de pesquisa em saúde no Brasil, as causas de seu sucesso e eventuais fracassos e as medidas possíveis de ajudá-los a contornar suas presentes dificuldades.By the end of the 19th century, after the advances in surgical asepsis and the understanding of the role of microorganisms in the etiology of many infectious diseases, research institutes in the public health area were created worldwide with the objectives of undertaking "scientific research into the causes, prevention and treatment of disease in man and animals and to prepare and supply protective and curative materials such as vaccines and antitoxins". To pursue these objectives the institutes hired the best scientists from everywhere. This was an exhilarating period for research in which discoveries proliferated. After that, institutes got into depression and even insolvency. Most recovered, many not. Many are still suffering from an "identity crisis". In this paper we analyze the fate of the health research institutes in Brazil, the causes of their success and eventual failures and the possible ways to get out of their current difficulties.

Methods:Sterilized explants were prepared by using 0.1%HgCl2 and 0.5%Bavistin and callus was obtained when cultured onto Murashige Skoog’s (MS) medium by using different concentrations and combination of 2,4-D, NAA, BAP, IAA, IBA with 3%sucrose and 0.8%agar. Induced callus was immediately transferred to MS medium containing at different concentrations of phytohormones for shootlets and rootlets induction respectively. Results:Sterilization treatment of 0.1%HgCl2 for 2-3 min and Bavistin 0.5%for 10-12 min showed the highest percentage of asepsis and survival rate. Maximum induction of callus was obtained from a combination of 2.0 mg/L 2,4-D and 0.5 mg/L NAA from leaf. Highest shootlets number (4.83±0.17) and length (3.8±0.16) cm were observed on full strength MS medium when fortified with BAP 4.0 mg/L and KIN 0.5 mg/L. Concerted efforts of BAP 2.0 mg/L and NAA 0.5 mg/L on full strength MS medium showed highest leaf number (6.77±0.94). In vitro raised shoots were allowed to root on different strengths of MS medium fortified with IAA and IBA at different concentrations. Experimentally, 3.0 mg/L IBA was enabled to induce maximum rootlets number (10.0±9.82) on full strength MS medium. Afterwards, regenerated shoots with well developed roots were successfully subjected to hardening process and were acclimatized. The survived plantlets showed 66.67%survival frequency without any morphological abnormality. Conclusions: The results demonstrated that different explants were good source of callus induction, morphology analysis as well as indirect plantlets regeneration.

    A study of a process known as plasma immersion ion implantation (PIII) of nitrogen at low voltages (< 4 kV) into three kind of samples: 1) austenitic stainless AISI 316-L steel plates, 2) ferritic stainless AISI 434 steel-based dentistry drills and 3) commercially pure titanium (CPTi) disks. On the case of CPTi the study was conducted in nitrogen- oxygen calibrated mixtures: 90% N-10% O, 80% N-20% O, 70% N-30% O and in 99.5% pure oxygen and 99.9% pure nitrogen. The PIII process was carried out by using a direct current plasma source controlled both in voltage and current, a negative voltage pulse modulator, a stainless AISI 304 steel vacuum chamber and a rod of the same material, horizontally located in the upper region of the chamber, which plays the role of anode in the plasma discharge. The purpose of the nitriding is forming a relatively thick layer on the surface of the steel specimens in order to enhance their both microhardness and general corrosion performances, desirable in medical applications. This layer contains interstitial nitrogen atoms ({approx}24% at.) which gives place to a deformed lattice (expanded phase) of the steel. Vickers microhardness and potentiodynamic tests (the latter in agreement to the norm ASTM G-61-89) confirm an increase of microhardness up to three times and a decrease of general corrosion rate in one order of magnitude. The nitriding of de dentistry drills is aimed at inhibiting the pitting corrosion produced by the asepsis process which results in pit nucleations, their propagation and consequent fractures when being under cyclic stress (fatigue). Scanning electron microscope micrographs reveal the risks involved in surpassing the critical treatment simple temperature of 450 C as the PIII process itself induces pitting. On its part, cyclic (ASTM G-61) potentiodynamic tests indicate an excellent pitting corrosion resistance of the samples treated under 450 C. In turn, the treatment of CPTi was meant to develop oxidized and

    Full Text Available Statement of Problem: Nowadays Mineral Trioxide aggregate (MTA is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments.Investigations have shown similar physical and chemical properties for Portland cement and Root MTA with those described for MTA.Purpose: The aim of this in vitro study was to evaluate the tissue reaction to implanted MTA, Portland cement and Root MTA in the mandible of cats.Materials and Methods: Under asepsis condition and general anesthesia, a mucoperiosteal flap, following the application of local anesthesia, was elevated to expose mandibular symphysis. Two small holes in both sides of mandible were drilled. MTA, Portland cement and Root MTA were mixed according to the manufacturers, recommendation and placed in bony cavities. In positive control group, the test material was Zinc oxide powder plus tricresoformalin. In negative control group, the bony cavities were left untreated. After 3,6 and 12 weeks, the animals were sacrificed and the mandibular sections were prepared for histologic examination under light microscope. The presence and thickness of inflammation, presence of fibrosis capsule, the severity of fibrosis and bone formation were investigated. The data were submitted to Exact Fisher test, chi square test and Kruskal-Wallis test for statistical analysis.Results: No statistically significant differences were found in the degree of inflammation,presence of fibrotic capsule, severity of fibrosis and inflammation thickness between Root MTA, Portland cement and MTA (P>0.05. There was no statistical difference in boneformation between MTA and Portland cement (P>0.05. However, bone formation was not found in any of the Root MTA specimens and the observed tissue was exclusively of fibrosis type.Conclusion: The physical and histological results observed with MTA are similar to those of Root MTA and Portland cement. Additionally, all of these three materials are biocompatible

    hygiene standards despite difficult practice conditions, exacerbated by supply problems. In all applications, hygiene involves a succession of closely-related, logical steps, which form an asepsis chain aimed at preventing the transmission of infection. Our survey shows that fundamental elements of hygiene require attention to achieve this aim. The cleaning, disinfection and sterilizing of floor surfaces and equipment should be improved and more widespread use made of disposable items. It is important to define the hygiene level required for particular treatments, taking into account the oral and dental micro flora and whether the equipment has been decontaminated, disinfected or sterilized. A piece of equipment is decontaminated if it has been mechanically cleaned and decontaminated. It is disinfected if these steps are followed by rinsing with sterile water, drying and conditioning. An item is described as sterilized if it is cleaned, decontaminated, rinsed, dried, conditioned and then sterilized. We found that a wide variety of chemicals were used to clean hands, surfaces and equipment. The nature and appropriate methods of use of these chemicals were not widely known. Understanding the chemical composition of these chemicals makes it possible to classify them into cleaning agents, detergents, decontaminating agents and disinfectants. The definition, choice and use of antiseptics and disinfectants should be strictly controlled. It is also vital that single-use disposable items are used only once and are never reused. Hygiene in the dental surgery is a chain of processes aimed at protecting the patient and the medical staff. There are many links in the chain, involving floor and surface hygiene, hand washing by dentists and dental assistants, washing of surgery linen and treatment of equipment. Dental practitioners should continually focus on ensuring that the chain of hygiene procedures is not broken, in their own interests as well as in those of their patients.

    cord stimulators for the management of severe and intractable pain. Complications after the implantation of the electrodes are infrequent, but some as breakage, infection and displacement have been reported. The case of a young technical agricultural engineer with a medical history of allergy to acarus is described. He developed a septic shock following the sting of an insect (Simu-lium Damnasum on the top right limb, being admitted to intensive care for 48 hours. During his hospital stay, he had severe neuropathic pain with a poor response to conventional treatment. Three and a half years after this event, the patient was sent to the Pain Management Unit, where the first stage of an electrode implantation for a spinal cord stimulator was carried out. The system was withdrawn after six days due to a Staphylococcus Aureus infection. A series of epicutaneous test for regular substances and for those from the spinal cord stimulator components were made. The likelihood of an allergy to some component of the implantable device, responsible for an inflammatory reaction and subsequent infection of the catheter, was ruled out. It is important to point out that careful asepsis is still the best means to avoid infections. In patients with a medical history of atopia or allergic reactions, allergic tests should be considered as a measure to prevent rejections of devices.

    animals often mask the signs of infection to avoid attracting predators (Wobeser 2006). Guidance specific to sterilization of electronic devices for implantation is limited in the wildlife record (Burger et al. 1994; Mulcahy 2003). Few biologists have been formally trained in aseptic technique, but most biologists know that electronic devices should be treated in some way to reduce the chance for infection of the host animal by bacteria, viruses, parasites, and fungi. Most biologists (73%) who implant devices into fishes believe aseptic techniques are important (Wagner and Cooke 2005). However, I maintain that many biologists find it difficult to place the concept of asepsis into practice in their work because of confusion about what constitutes aseptic technique, a lack of surgical knowledge and training, the perception of increased costs, or the belief that aseptic surgeries are impractical or unnecessary for their application. Some have even argued that, while compromising surgical techniques in the field might result in complications or mortalities, the money saved would allow for a compensatory increase in sample size (Anderson and Talcott 2006). In this paper I define aseptic surgical techniques, document the legal and professional guidance for performing aseptic surgeries on wild animals, and present options for sterilizing electronic devices and surgical instruments for field use.

    Full Text Available BACKGROUND: The choice of wound closure after a surgical procedure has been a surgeon’s dilemma . The concerns have been as to how fast , uneventful , less painful , with minimal complications and comfortable will the patient’s recovery be. A well - known technology is surgical staples which are easier to use , less time consuming and a needle free method o f wound closure. OBJECTIVE: To compare skin staples with non - absorbable skin suture for skin closure in surgical laparotomy procedures for the following character : wound infection , dehiscence , cosmesis and postoperative pain . METHODS: This is a comparative study conducted on 100 patients divided in two groups randomly at Bapuji Hospital for cases undergoing surgical laparotomy procedures. Skin closure was done with 2 - 0 polyamide skin sutures in one group and skin closure was achieved with skin staples in th e other group. The outcome of wound was assessed on 3rd , 5th and 7th postoperative days using ASEPSIS score. Wound cosmesis was assessed on the 7th postoperative day and followed up at 1st month and 3rd month , using modified Hollander cosmesis scale. Postoperative pain was assessed using the visual analogue scale on the 1st , 3rd and 7th postoperative days. RESULTS : The mean wound ASPESIS scores on day 3 for skin staples and sutured group was 0.28 and 0.36 (p=0.7 respectively.

    Full Text Available INTRODUCTION: Hypotension during Spinal Anesthesia Subarachnoid block for LSCS is secondary to the sympathetic blockade and aorto - caval compression by the uterus and it can be deleterious to both fetus and mother. Ephedrine and phenylephrine improve venous return after sympathetic blockade during Subarach noid block. AIMS AND OBJECTIVES: The objective of this study was to assess the role of Intramuscular phenylephrine and ephedrine and to compare the efficacy of Intra muscular Phenylephrine and ephedrine in LSCS to avoid post spinal hypotension. MATERIALS A ND METHODS: Ninty patients undergoing subarachnoid block with 0.5% Bupivicaine heavy for LSCS in Left Lateral Position in L 3 - L 4 Interspinous space via 25 G Spinal Needle under full asepsis were randomly divided into 3 groups. GROUP A: Received neither i.m. phenylephrine nor i.m. ephedrine. Only Co - loading with crystalloid. GROUP B: Received intramuscular ephedrine (25 mg 10 minute prior to spinal anaesthesia & Co - loading with crystalloid. GROUP C : Received intramuscular phenylephrine (2 mg 10 minute prior to spinal anaesthesia. & Co - loading with crystalloid. PATIENT SELECTION CRITERIA : INCLUSION CRITERIA: Full Term Pregnancy, ASA Grade - I and Grade – II . EXCLUSION CRITERION: Contraindications for spinal block, coagulopathies, eclamptic and preeclampt ic patient. INVESTIGATION REQUIRED : Routine Investigation , CBC , PTT, APTT, INR, Urine Investigation . DISCUSSION : Phenylephrine and ephedrine are comparable vasopressors when used to treat hypotension during caesarian section after spinal anaesthesia. Signi ficant difference in HR between groups can primarily attributed to the decline in HR observed with phenylephrine and increase i n HR associated with Ephedrine. The incidence of tachycardia was significantly higher in Ephedrine group due to its B1 - agonist pr operty . Furthermore, the incidence of fetal tachycardia with Ephedrine was more significant in another study

    Objective To observe the effects of intravenous glutamine (Gln) support on plasma lipopolysaccharide (LPS,endotoxin) concentration and acitvities of phospholipase A2(PLA2) and neutrophil elastase (NE) in taurocholate-induced acute severe pancreatitis (ASP) in pigs. Methods Twenty-one pigs weighed 16 kg-22 kg were randomly divided into four groups: including sham-controlled group (sham group, n=5), ASP-controlled group(ASP group, n=5), ASP+glycine controlled group(Gly group, n=5) and ASP+Gln supported group (Gln group, n=6). Anesthesized pigs were subjected to ASP induced by injecting 1 ml/kg of mixed solution of 5% sodium taurocholate and 8 000~10 000 BAEE units trypsin/ml into pancreas via pancreatic duct, which was replaced by 0.9% sodium chloride phosphate buffer solution to be taken as sham group. Blood samples from caval vein was collected for the determinations of Gln, LPS, NE and PLA2. Plasma glutamine were measured by high performance liquid chromatography. Systemic plasma endotoxin levels was quantified by the chromogenic limulus amebocyte lysate (LAL) technique. All pigs were intravenously sacrificed by injecting 20 ml of 10%KCl. Anything involved in the processes of the sampling, preserving, measuring and so on had to be depyrogenated and to be asepsis. Results ASP porcine induced by sodium taurocholate mixed solution was associated with awfully lowed glutamine concentration but higher LPS, PLA2 and neutrophil elastase (NE) activities in plasma. There existed highly significant difference compared with the normal values (all P<0.01 ). Intravenous glutamine support could effectively prevent the decrease of systemic plasma glutamine level (P<0.01), and reduced the higher levels of systemic plasma LPS and the activities of plasma NE and PLA2 followed by acute severe pancreatitis induced by the mixed solusion of 5% sodium taurocholate and trypsin in pigs (all P<0.01), but all were still higher than the normal values except for NE activities at 72 h

The proposal is to mould the cavity, after local asepsis with fresh water plus soap, with a gelatinous plastic which contains silice, potassium alginate, calcium sulphate,magnesium oxide commercialized under the name of jeltrate® (Dentsply Laboratory, by solving 9-5g of jeltrate® in 20ml of fresh water and applying the gel on the ulcer which solidifies in 5 minutes. This mould is then filled with a self polymerising aciylic and its volume measured either by weight (by using an analytical balance - technique 1 - or by water displacement by applying Archimeds'principle - technique 2. We shoiu data in a field trial before and after 20 days treatment in 20 patients using three different schedules as follows: 7 received pentamidine isethionate, 7 patients received aminosidine sulphate and 6 received meglumine antimoniate. Tloe results point out that there was a uniforme reduction of ulcer volume occurred during this period in the three groups, in both technique. Regarding the therapeutic schedules we are sure that there was a significant statistical difference between the three schedules using the TStudent Test, which showed that aminosidine sulphate produced a better volume reduction of the ulcer than the other drugs. Serial moulds reflect clinical healing and ai'e a permanent record. We conclude that the measure of the volume of the skin ulceration can be usefull in the therapeutic evaluation, as a practical and cheap procedure, and 7nay be used in field trials..
