Pneumatosis cystoides intestinalis

1977

Bei der Pneumatosis cystoides intestinalis handelt es sich um Gascysten von Stecknadelkopf- bis Kirschgrose, die sich in der Wand des Dunndarms, des Coecums und im linksseitigen Dickdarm finden. Aber auch ein Befall des gesamten Colons ist beschrieben worden. Die Erkrankung kann in jeder Altersstufe auftreten. Histologisch lassen sich bei Serienschnitten kommunizierende Systeme von Gascysten nachweisen, die bei Jugendlichen submucos und im hoheren Alter subseros liegen. Die Zusammensetzung des Gases entspricht der der Atemluft.

Veränderung von Inzidenz und Mortalität von Kopf-Hals-Malignomen in Rheinland-Pfalz, 2000–2009

2014

Hintergrund: Epidemiologische Daten zu Kopf-Hals-Malignomen werden trotz ihrer anatomisch-histologischen Heterogenitat oft aggregiert berichtet. In Deutschland gibt es bisher nur wenige Studien, die Trends von Inzidenz und Mortalitat detailliert nach Tumorentitaten analysiert haben. Weiterhin ist wenig daruber bekannt, ob die Inzidenz von HPV-assoziierten Tumorentitaten der Kopf-Hals-Region zugenommen hat. Methoden: Anhand von Krebsregisterdaten aus Rheinland-Pfalz von 2000–2009 wurden altersstandardisierte Inzidenz- und Mortalitatsraten fur alle Kopf-Hals-Tumorentitaten einzeln und nach Lokalisationsgruppen, die HPV-assoziiert sein konnten, berechnet. Zeitliche Trends wurden mittels Joinpo…

Enhancement of Gene Expression by Somatic Hybridization with Primary Cells: High-Level Synthesis of the Hepatitis B Surface Antigen in Monkey Vero Ce…

1990

Vero cells transfected with the S gene encoding the surface antigen (HBsAg) of the hepatitis B virus (HBV) synthesize HBsAg at low levels. We have obtained a large increase in S gene expression by somatic hybridization of Vero cells with primary hepatocytes, which are the natural target cells for HBV infection. Fusion with cells other than hepatocytes did not enhance expression of the S gene. The Vero/hepatocyte hybrid clones analyzed are stable and have maintained a high level of HBsAg synthesis over prolonged periods. Hybrid cell lines may be of general interest for the high-level synthesis of proteins using cloned genes.

Microbiota e HPV nel carcinoma orale

2021

La carcinogenesi è un processo multifattoriale in cui sono coinvolti differenti fattori esogeni; tra questi, il microbiota sembra svolgere un ruolo attivo nei mec- canismi di sviluppo del carcinoma orale [1]. Nella presente trattazione saranno descritti i principali aspetti epidemiologici, clinici e patogenetici che vedono coinvolto il microbiota orale nel processo di carcinogenesi omodistrettuale. A tal proposito, per facilità di trattazione, è stata condotta una distinzione del microbiota orale in due gruppi: microbiota orale batterico e microbiota orale non batterico (i.e. Candida spp, Human Papilloma Virus). Fra i microrganismi appartenenti a quest’ultimo gruppo, verrà condotta una disa…

Detection of Human Papillomavirus DNA in cervical samples: analysis of the new PGMY-PCR compared to Hybrid Capture II, MY-PCR and a Two-step nested P…

2004

The PGMY-PCR for human papillomavirus (HPV) was evaluated, in parallel with nested PCR (nPCR), in samples with noted Hybrid Capture II (HCII) and MY-PCR results. PGMY-PCR detected HPV DNA in 2.5% of HCII-negative-MY-PCR-negative samples and in 71.7% of HCII-positive-MY-PCR-negative samples; also, it detected the MY-PCR-negative-nPCR-negative types HPV-42, HPV-44, HPV-51, HPV-87, and HPV-89.

Augsta riska cilvēka papilomas vīrusa detekcija nieres transplantāta recipientēm ar imūnsistēmas supresiju dinamikā

2018

Šī darba ietvaros ar dāžadām testēšanas metodēm detektēja augsta riska cilvēka papilomas vīrusa (HPV) klātbūtni nieres transplantāta recipienšu vidū, kā arī pētīja vīrusa slodzes un detektējamības izmaiņas periodā no 2 nedēļām līdz 1 gadam pēc transplantācijas. Pētījumā tika iesaistītas 35 nieres transplantāta recipientes un 79 praktiski veselas sievietes kā kontroles grupa. Pētījumā tika izmantotas dzemdes kakla iztriepes un perifērās asinis plazmas izdalīšanai. Iegūtos rezultātus salīdzināja ar kontroles grupu, lai spriestu par imūnsupresēto indivīdu paaugstināto risku HPV infekcijai. Dzemdes kakla iztriepju šūnu suspensijās gan recipienšu, gan kotroles grupas sievietēm HPV DNS sākotnēji …

Human papillomaviruses in oral carcinoma and oral potentially malignant disorders: a systematic review.

2011

Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. Methods: Systematic review was performed using PubMed (January 1966-September 2010) and EMBASE (January 1990-September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk of bias was based on characteristics of study group, appr…

Human papillomavirus-associated cancers: a survey on otorhinolaryngologists' knowledge and attitudes on prevention.

2016

Human papillomavirus (HPV) infection is a recognised causal factor associated with oropharyngeal cancers. The global burden of HPVrelated oropharyngeal cancers is on the increase and is predicted to surpass the burden of cervical cancer in the near future. As evidence is accumulating on the potential effectiveness of an HPV vaccine in controlling the oropharyngeal cancer epidemic; otorhinolaryngologists assume a key role - not only in the diagnosis and treatment of HPV-related cancers - but also in educating and advocating on HPV prevention. We conducted a survey to assess Italian otorhinolaryngologists' knowledge and attitudes regarding HPV infection, HPV-related oropharyngeal diseases and…

Factors Associated with HPV Vaccine Refusal among Young Adult Women after Ten Years of Vaccine Implementation

2018

In Italy, the Human Papillomavirus (HPV) vaccination was implemented for twelve years old girls in 2007, but its coverage was lower than the recommended level. Sicily is one of the Italian administrative regions with lower vaccination coverage, with a value of 59% for those born in 1996 increasing to 62% coverage for those born in 1999. The aim of the study was to investigate factors associated with the refusal of HPV vaccination among young adult women of Palermo, Italy. The study was approved by the Ethics Committee of the Policlinico “Paolo Giaccone” Hospital (Palermo 1) and the questionnaire was validated in a convenience sample representing 10% of the young women. A cross-s…
