Non-wild-type cryptococcosis in a child with multivisceral organ transplant who owned bird pets.
2020
Cryptococcosis is the third most common invasive fungal infection in solid-organ transplant recipients, although it is rarely reported in transplanted children. It typically appears as a late-onset infection with central nervous system or pulmonary involvement. We present a case of cryptococcosis caused by a non-wild strain in a 10-year-old child who owned two pet birds, and review the existent literature.
Multiple pulmonary and multivesicular interatrial septum hydatid cysts in a native italian patient
2008
Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation. A rare case of multivesicular interatrial septum hydatid cyst with multiple pulmonary involvement in a native Italian farm labourer is reported. Clinical, radiological, serological and histological findings are described. MR imaging showed the exact anatomic location and the multivesicular nature of the cardiac cyst and was useful in planning surgical treatment. A successful outcome was achieved with a combination of…
Bacterial Contamination of Anterior Chamber Fluid Following Non-complicated Cataract Surgery
1993
Objective: To study the anterior chamber contamination during non-complicated cataract surgery and its relationship with normal conjuctival organisms. Setting: Ophthalmology Department, La Fe Hospital, University of Valencia. Patients: Forty patients who had undergone cataract extraction using either ECCE, phacoemulsification or nucleus fracture methods. Results: Positive cultures of aqueous humour were obtained in 32.5% of cases. The most commonly isolated organism was Staphylococcus coagulase-negative. Only in 7.7% of cases was the microorganism found in the conjunctiva the same as that found in the anterior chamber. The inoculum size ranged between 20 and 160 colonies/ml. One of the case…
Incidence of Staphylococcus aureus in meals from cafeterias
2002
A study to determine the incidence of Staphylococccus aureus in 705 meals from several cafeterias in Valencia, Spain was undertaken. Out of the 705 studied meals, 81 samples (I I. I %) had coagulase positive staphylococci with a range of S. aureus from 100 to 53000 cfu/g. me four highest values (> l0,ooO S. aureus &/g) were obtained with Russian type salad, meatballs, chicken croquettes and salad. These products involved more handling stages. These data show that food handlers may contribute to food poisoning and that there are some handling practices that require more attention.
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…
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…
Hydatidosis of the Central Nervous System in South America
2014
In this chapter, we reviewed the epidemiology of cystic hydatidosis in South America, especially focusing on hydatidosis of the central nervous system. Echinococcus granulosus and E. multilocularis are the most frequent species in humans. Hydatidosis is endemic in several Latin American countries, including Argentina, Bolivia, Brazil, Chile, Peru, and Uruguay. The global occurrence of hydatid cysts of the central nervous system is uniformly low, with a reported incidence of 0.9–2.1 % of all cases of hydatidosis.
Some epidemiological aspects of nosocomial infections. Antibiotic sensitivity rates of isolated bacteria from nosocomial infections - A prospective s…
2014
Results The total number of isolated strains was 413, 231 in 2012 and 182 in 2013. In the intensive care units 151 nosocomial infections were identified; 88 strains in the Surgical Department, 27 strains in the Department of Gynecology and Obstetrics, 24 strains in the Department of Neurosurgery and 23 in the Orthopedic Department. 19 strains were identified in the Neurology Department and also in the Internal Medicine Department, 17 strains were identified in the Urology Department, 14 in the Aesthetic Surgery Department, 8 in the Nephrology Department, 8 in the Hematology Department and 5 in the Gastroenterology Department. 3 strains were isolated in each of the following departments: Dia…
Molecular genetics of Staphylococcus epidermidis biofilms on indwelling medical devices.
2005
Staphylococcus epidermidis is an opportunistic pathogen associated with foreign body infections and nosocomial sepsis. The pathogenicity of S. epidermidis is mostly due to its ability to colonize indwelling polymeric devices and form a thick, multilayered biofilm. Biofilm formation is a major problem in treating S. epidermidis infection as biofilms provide significant resistance to antibiotics and to components of the innate host defenses. Various cell surface associated bacterial factors play a role in adherence and accumulation of the biofilm such as the polysaccharide intercellular adhesin and the autolysin AtlE. Furthermore, recent studies have shown that global regulators such as the …
