Ureterosciatic Hernia A Rare Cause of Pyonephrosis
1989
A female patient presented as an emergency case with pyonephrosis and septicemia as a result of ureterosciatic hernia. Septicemia was treated successfully by immediate percutaneous nephrostomy tubing. After complete disappearance of symptoms, the hernia was closed operatively. Topographic anatomy of ureterosciatic hernia is presented.
Intraperitoneal injection of tetracyclines protects mice from lethal endotoxemia downregulating inducible nitric oxide synthase in various organs and…
1997
We have tested whether tetracyclines (TETs) are able to protect mice from lipopolysaccharide (LPS)-induced shock, a cytokine-mediated inflammatory reaction. Mice, injected with a single dose of tetracycline base (TETb; 1.5, 10 and 20 mg/kg of body weight) or doxycycline (DOXY; 1.5 mg/kg), were significantly protected from a lethal intraperitoneal injection of LPS (500 micrograms per mouse). TETs acted in early events triggered in response to LSP; in fact, they were no longer significantly protective if injected more than 1 h after the injection of endotoxin. LPS-treated mice protected by TETs showed a significant inhibition of tumor necrosis factor alpha (TNF-alpha), interleukin-1 alpha (IL…
Efficacy of NaOCl/H2O2irrigation and GaAlAs laser in decontamination of root canals in vitro
2003
Background and Objectives To investigate the bactericidal effect of an 809 nm semiconductor laser alone, and in combination with NaOCl/H2O2 irrigation in root canals in vitro. Study Design/Materials and Methods A total of 72 human single-rooted teeth extracted for periodontal reasons were included. The crowns were removed, the roots shortened to a length of 12 mm, and the canals enlarged up to an apical size of #50 file. The specimens were autoclaved and incubated with a suspension of Streptococcus sanguinis (ATCC 10556). Laser irradiation was performed on a PC-controlled XY translation stage. A 200 micron optic fiber was used. Twelve specimens were irradiated at a power output of 1.5, 3.0,…
Antimicrobial therapy in neonatal intensive care unit
2015
Severe infections represent the main cause of neonatal mortality accounting for more than one million neonatal deaths worldwide every year. Antibiotics are the most commonly prescribed medications in neonatal intensive care units (NICUs) and in industrialized countries about 1% of neonates are exposed to antibiotic therapy. Sepsis has often nonspecific signs and symptoms and empiric antimicrobial therapy is promptly initiated in high risk of sepsis or symptomatic infants. However continued use of empiric broad-spectrum antibiotic treatment in the setting of negative cultures especially in preterm infants may not be harmless. The benefits of antibiotic therapy when indicated are clearly enor…
Influence of microbiology on endodontic failure. Literature review
2019
Background: The main cause of endodontic failure is the persistence of microorganisms that cause an intraradicular or extratradicular infection and that become resistant to disinfection measures. The objective of this review is to identify the microbiota associated with endodontic failure, as well as the reasons why these microorganisms are capable of surviving basic disinfection measures. Material and Methods: Systematic search of scientific articles in the databases PubMed with the following keywords “Endodontic Infections”, “Endodontic Microbiology”, “Endodontic Failure”, “Enterococcus Faecalis”, “Endodontics Retreatment” was carried out. Case reports and articles with publication date p…
Physical Activity Differentially Affects the Cecal Microbiota of Ovariectomized Female Rats Selectively Bred for High and Low Aerobic Capacity
2015
The gut microbiota is considered a relevant factor in obesity and associated metabolic diseases, for which postmenopausal women are particularly at risk. Increasing physical activity has been recognized as an efficacious approach to prevent or treat obesity, yet the impact of physical activity on the microbiota remains under-investigated. We examined the impacts of voluntary exercise on host metabolism and gut microbiota in ovariectomized (OVX) high capacity (HCR) and low capacity running (LCR) rats. HCR and LCR rats (age = 27 wk) were OVX and fed a high-fat diet (45% kcal fat) ad libitum and housed in cages equipped with (exercise, EX) or without (sedentary, SED) running wheels for 11 wk (…
Comparing medical treatments for Crohn’s disease
2013
The drugs available for inflammatory bowel disease are aminosalicylates, antibiotics, steroids, immunosuppressors and biologics. The effectiveness of these drugs has been evaluated in many randomized clinical trials, mainly versus placebo. Few studies have been conducted comparing the different drugs among themselves, owing to the methodological problems raised by comparative trials, such as sample size and blindness. This review focuses mainly on the randomized clinical trials that have compared different treatments. Of course comparisons are mainly between drugs used in a particular setting (mild, moderate and severe disease). However, on many occasions there is no homogeneity in these cl…
Epidemiology of pneumococcal disease in children in Germany
2001
UNLABELLED Recently published and as yet unpublished data allow a reasonable estimate of the annual burden of pneumococcal disease in Germany. At least 277,000 episodes of otitis media and at least 2,000 episodes of sinusitis occur in children under the age of 5 y. Pneumococcal meningitis was found in 200 children under the age of 16 y; the estimate for all age groups ranges from 450 to 1100 cases. Of approximately 150,000 cases of ambulatory pneumococcal pneumonia, at least 63,000-105,000 patients are hospitalized each year. CONCLUSION Further studies of pneumococcal epidemiology in Germany are needed, and continued surveillance will be necessary for a better understanding of the overall b…
Oral capecitabine and Vinorelbine in Metastatic Breast Cancer. A Retrospective Analysis of Tolerability and Activity
2012
ABSTRACT Background The purpose of this study was to retrospectively analyze toxicity profile and activity of an all-oral combination schedule of Capecitabine (Cape) and Vinorelbine (VNR) in metastatic breast cancer (MBC) patients (pts). Methods All pts treated had a histological confirmed diagnosis of breast cancer (BC). Each 3-week cycle of treatment consisted of 500 mg/m2 cape twice daily (2 weeks on, 1 week off), and 60 mg/m2 VNR on days 1 and 8. Results From June'07 to December'11 we analyzed 77 MBC pts. Median age was 52 years (range 34-73). 58 pts (75,3%) had a performance status (PS) ECOG 0; 13 pts (16,8%) PS1, 6 pts (7,8%) PS2. 5 pts (6,5%) had metastatic disease at time of diagnos…
Modern Strategies in the Prevention of Implant-Associated Infections
2005
The application of medical devices either for temporary or permanent use has become an indispensible part of almost all fields of medicine. However, foreign bodies are associated with a substantial risk of bacterial and fungal infections. Implant-associated infections significantly contribute to the still increasing problem of nosocomial infections. To reduce the incidence of such infections, specific guidelines providing evidence-based recommendations and comprising both technological and nontechnological strategies for prevention have been established. Strict adherence to hygienic rules during insertion or implantation of the device are aspects of particular importance. Besides such basi…
