Members of the genus Myroides are aerobic Gram-negative bacteria that are common in environmental sources, but are not components of the normal human microflora. Myroides organisms behave as low-grade opportunistic pathogens, causing infections in severely immunocompromised patients and rarely, in immunocompetent hosts. A case of Myroides odoratimimus cellulitis following a pig bite in an immunocompetent child is presented, and the medical literature on Myroides spp. soft tissue infections is reviewed.
Although the role of human papillomavirus (HPV) in the development of uterine cervical cancer is well established, the role of HPV in lung carcinogenesis remains controversial. The detection rates of HPV DNA are subject to a wide variation from 0 to 100%. This is partly influenced by the detection techniques employed. To elucidate the impact of HPV infection on lung parenchyma, we analyzed 100 non-small cell lung cancer (NSCLC) specimens (39 squamous cell carcinomas, 50 adenocarcinomas, 5 samples with characteristics of both squamous cell and adenocarcinoma, 5 undifferentiated and 1 large cell carcinoma) from the region of Crete, Greece. Sixteen non-cancerous samples served as the negative controls. DNA was extracted from 100 paraffin-embedded tissue sections obtained from NSCLC patients. The specimens were examined for the detection of HPV DNA by Real-Time PCR using GP5+/GP6+ primers. Furthermore, the HPV-positive samples were subjected to genotyping. In contrast to the absence of viral genomes in the control samples, HPV DNA was detected in 19 NSCLC specimens (19%). In particular, 4 squamous cell carcinomas, 12 adenocarcinomas, 1 sample with characteristics of both squamous cell and adenocarcinoma, and 2 undifferentiated samples were HPV-positive. The distribution of HPV genotypes was as follows: HPV 16: eight cases (42.1%); HPV 11: three cases (15.8%); HPV 6: one case (5.2%); HPV 59: one case (5.2%); HPV 33: two cases (10.5%); HPV 31: two cases (10.5%) and HPV 18: two cases (10.5%). The presence of HPV in the tumor samples provides evidence of the potential role of HPV in NSCLC and strongly argues for additional research on this issue.
Carbapenems are broad-spectrum antibiotics increasingly used for the treatment of severe infections. We evaluated the effects of four carbapenems given as monotherapies or in combination with amikacin on the level of gastrointestinal colonisation by Candida albicans in a previously established mouse model. Adult male Crl : CD1 (ICR) BR mice were fed chow containing C. albicans or regular chow. The mice fed with Candida chow had their gut colonised by the yeast. Both groups were subsequently given imipenem, meropenem, ertapenem, doripenem or their combination with amikacin or normal saline subcutaneously for 10 days. Stool cultures were performed immediately before, at the end and 1 week after discontinuation of treatment. Candida-colonised mice treated with the antibiotics had higher counts of the yeast in their stools than control C. albicans-colonised animals treated with saline. All four carbapenems and their combination with amikacin caused a significant increase in C. albicans concentration. Mice fed regular chow and treated with the study antibiotics or saline did not have any Candida in their stools. Dissemination of Candida was not detected in any animal. These data suggest that carbapenems and carbapenem plus amikacin induce substantial increases in the murine intestinal concentration of C. albicans.
Παρά το ότι ο ρόλος του ιού των ανθρωπίνων θηλωμάτων ( Human Papilloma virus, HPV) στην εμφάνιση του καρκίνου του τραχήλου της μήτρας είναι καλά τεκμηριωμένος, ο ρόλος του HPV στην καρκινογένεση του πνεύμονα παραμένει αμφιλεγόμενος. Η συχνότητα ανίχνευσης του HPV DNA υπόκεινται σε ευρεία διακύμανση, από 0 έως 100 %. Αυτό εν μέρει οφείλεται στην τεχνική ανίχνευσης που χρησιμοποιήθηκε. Για να διευκρινίσουμε την επίδραση της HPV λοίμωξης στο πνευμονικό παρέγχυμα, αναλύσαμε 100 δείγματα από μη-μικροκυτταρικό καρκίνο πνεύμονα (39 πλακώδη καρκινώματα, 50 αδενοκαρκινώματα, 5 αδενοπλακώδη, 5 αδιαφοροποίητα και 1 μεγαλοκυτταρικό) από την περιοχή της Κρήτης στην Ελλάδα. Ως αρνητικός μάρτυρας χρησιμοποιήθηκαν 16 δείγματα υγειούς πνευμονικού ιστού. Έγινε εκχύλιση DNA από 100 τομές μονιμοποιημένες σε παραφίνη που πάρθηκαν από ασθενείς με μη-μικροκυτταρικό καρκίνο του πνεύμονα. Τα δείγματα εξετάσθηκαν για την παρουσία του HPV DNA με την τεχνική της Real Time PCR χρησιμοποιώντας τους γενικούς εκκινητές GP5+/GP6+. Επιπλέον, τα HPV θετικά δείγματα υπεβλήθησαν σε γονοτυπική ανάλυση. Σε αντιδιαστολή με την απουσία του ιϊκού γονιδιώματος στα δείγματα ελέγχου, HPV DNA ανιχνεύθηκε σε 19 από τα 100 εξετασθέντα δείγματα (19%). Συγκεκριμένα, 4 πλακώδη καρκινώματα, 12 αδενοκαρκινώματα, 1 αδενοπλακώδες και 2 αδιαφοροποίητα ήταν HPV θετικά. Η κατανομή των γονοτύπων του HPV ήταν η ακόλουθη : HPV 16 : 8 περιστατικά (42,1 %) , HPV 11 : 3 περιστατικά (15,8 %) , HPV 6 : 1 περιστατικό (5,2 %) , HPV 33 : 2 περιστατικά (10,5 %) , HPV 31 : 2 περιστατικά (10,5 %) και HPV 18 : 2 περιστατικά (10,5 %) . Η παρουσία του HPV στα δείγματα από καρκίνο παρέχει στοιχεία για τον πιθανό ρόλο του στο μη-μικροκυτταρικό καρκίνο του πνεύμονα και υποδεικνύει την ανάγκη για περαιτέρω έρευνα στο συγκεκριμένο πεδίο.
