Febre persistente e expectoração hemoptóica – caso clínico

Foreign body aspiration (FBA) is a common and serious problem in children. Considering that signs and symptoms can be non-specific and subtle, it is of utmost importance to recognize vulnerable patient groups, combine an accurate history with complete physical examination, and follow a structured diagnostic approach towards correct diagnosis. In the present case, a high index of suspicion was essential to prevent a delay in FBA diagnosis, discuss the appropriate management strategy and improve patient outcomes.info:eu-repo/semantics/publishedVersio

Tuberculous otitis media with facial paralysis: microbiological and clinical study

Tuberculosis is a serious infectious disease affecting various organs and tissues even if the lung is the most commonly involved site.A case of tuberculous otitis media in a patient who had no history of tuberculosis is herewith presented with the aim of increasing the awareness of this disease whose diagnosis is often delayed because either of the rarity of this pathologic condition or of its usually indolent course

Multi-year prevalence and macrolide resistance of Mycoplasma genitalium in clinical samples from a southern Italian hospital

The use of azithromycin for the treatment of Mycoplasma genitalium infections has led to resistance to macrolides. From July 2014 to July 2020, 7150 samples were analysed for the detection of sexually transmitted infections at the Policlinico of Bari. A total of 67/7150 samples (0.93%) were positive for MG DNA and 47 samples were analysed for the evaluation of six azithromycin resistance-associated mutations. In 5/47 samples, the A2058G mutation was detected (10.63%). Although the cases of positive MG samples and mutations are low in our reality, diagnostic tests to detect azithromycin resistant-associated genes may provide a convenient way to monitor resistance rate

Rapid recovery of Mycobacterium tuberculosis complex from clinical specimens using the BACTEC 9000 MB system, a new automated fluorimetric technique

Objective: To evaluate the new non-radioactive automated method BACTEC 9000 MB system for the rapid detection of mycobacteria in clinical specimens.Methods: Ninety clinical specimens from 90 patients with a clinical diagnosis of tuberculosis were tested by both BACTEC 9000 and standard microbiological methods, and the results compared.Results: The BACTEC 9000, in comparison with the standard method, showed significantly higher detection rates (45 of 90 positive versus 34), shorter time to culture positivity (mean time 18.8 versus 27.4 days) and lower contamination rate (2.2% versus 5.5%).Conclusions: These results encourage the use of this new system and suggest its use in microbiological laboratories involved in mycobacteriology

What we have learned for the future about COVID-19 and healthcare management of it?

Background and aim of the work: COVID-19 is a current global pandemic. However, comprehensive global data analyses for its healthcare management are lacking. Methods: In this study we have researched through published scientific articles and international health care guidelines to find out actually about our knowledge for this new pandemic from SARS-CoV-2 and related COVID-19 disease that emerged from December 2019 in China in order to better manage this health emergency. Results: The pathogens represented by microorganisms (bacteria, mycetes or viruses) show their effect after days and are responsible for epidemics/pandemics as dangerous as the greater their possibility of transmission, especially by inhalation, and therefore their infectivity. Conclusions: The appearance of new pathogenic viruses for humans such as the COVID -19, which previously were found only in the animal world occurs through the spillover (is the third documented of an animal coronavirus to humans), it is thought that it could also be the same also for the origin of this virus. Furthermore, the trend of this pandemic in one of the countries most affected by Italy after China was also considered

In vitro activity of ceftazidime/avibactam alone and in combination with fosfomycin and carbapenems against KPC-producing Klebsiella pneumoniae

KPC-producing Klebsiella pneumonia (KPC-Kp) represents a major therapeutic challenge in critically ill patients. Ceftazidime-avibactam (CAZ-AVI) is a new effective drug against KPC-Kp but, due to emerging resistant strains during monotherapy, the association with a second antibiotic has been advocated. Therefore, intravenous fosfomycin may be a possible choice for combination therapy. The aim of this study was to evaluate the in vitro susceptibility of CAZ-AVI alone and in combination with fosfomycin and carbapenems against KPC-Kp clinical isolates by E-test method. The combination of CAZ-AVI with carbapenems showed synergistic activity, whereas with fosfomycin showed addictive activity, suggesting that fosfomycin may be a carbapenem-sparing strategy in antimicrobial stewardship programs

Tuberculous Otitis Media with Facial Paralysis: A Clinical and Microbiological Diagnosis—A Case Report

The tuberculosis of the ear is rare, and in most cases the clinical picture resembles that of a chronic otitis media. The diagnosis is often delayed, and this can lead to irreversible complications such as hearing loss and/or facial paralysis. In view of its rare occurrence, we report a case of primary tuberculous otitis media in a 87-year-old female patient. The diagnosis was made on the basis of both histological and microbiological findings. In particular, gene amplification techniques such as real-time polymerase chain reaction are useful method for rapid diagnosis and detecting tuberculous bacilli usually present at very low number. Early diagnosis is essential for the prompt institution of antituberculous therapy

Sopravvivenza di microrganismi potenzialmente patogeni su superfici porcellanate

È stata valutata la capacità di sopravvivere sulla superficie inerte porcellanata di tazzine da caffè di quattro microrganismi potenzialmente patogeni (Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli). Dopo inoculazione è stata dimostrata capacità di sopravvivenza fino a 24 ore di Streptococcus pyogenes, Staphylococcus aureus ma non di Pseudomonas aeruginosa, Escherichia coli. Questi dati suggeriscono il potenziale ruolo patogeno giocato dalle superfici di stoviglie di largo uso nella trasmissione di infezioni da alcuni microrganismi gram-positivi

Linfopenia B: Reporte de Casos

1 p.La linfopenia B (<2%) es un hallazgo poco frecuente. Cuando se acompaña de niveles séricos de inmunoglobulinas (Igs) menores a 2DS para la edad permite realizar un diagnóstico (Dx) posible de Agammaglobulinemia (AG).

Virulence and in vitro antifungal susceptibility of Candida albicans and Candida catenulata from laying hens.

Funder: Università degli Studi di Bari Aldo MoroIn spite of evidence that domestic and wild birds may act as carriers of human pathogenic fungi, data on the role of laying hens as reservoirs of drug resistant and virulent yeasts is lacking. Here, we assess several virulence factors (phospholipase and haemolysin activity) and the antifungal susceptibility profiles of 84 Candida albicans and 17 Candida catenulata strains isolated from cloacae (group A), faeces (group B) and eggs (group C) of laying hens. Of these strains, 95% C. albicans and 23% C. catenulata strains displayed phospholipase and haemolytic activities. For C. albicans, the highest values of phospholipase (Pz = 0.62) and haemolytic activities (Hz = 0.49) were recorded among the strains from group C whilst for C. catenulata (Pz = 0.54; Hz = 0.49) among those from group A. High minimum inhibitory concentration (MIC) values for azoles and amphotericin B (AmB) were recorded irrespective of their sources in all C. albicans strains. A total of 22 C. albicans strains were multidrug resistant, displaying resistance to fluconazole, itraconazole (ITZ), voriconazole (VOR) and posaconazole (POS). All C. catenulata strains from group C were resistant to ITZ, POS, micafungin and anidulafungin and susceptible to AmB. In this study, C. albicans and C. catenulata isolated from the cloacae, faeces and eggs of laying hens produced phospholipase and haemolysin and might be multidrug resistant. In the environment (faeces) or in eggs, C. albicans and C. catenulata strains might acquire pathogenic virulence traits and/or show multidrug resistance profiles. Based on these results, breeding and handling of laying hens and/or eggs may have implications for human and animal health
