The role of human papillomavirus (HPV) in the development of lung and esophageal cancer remains inconclusive, which is in contrast to the established role HPV plays in the development of uterine cervical cancer. One of the reasons for this is the difference among reported HPV infection rates in these cancers. An analysis of 485 lung and esophageal cancers (176 lung squamous cell carcinoma, 128 lung adenocarcinoma, 181 esophageal carcinoma) in eight institutions in Asia (Tokyo, Kochi, Kagoshima, and Okinawa, Japan; Seoul and Daegu, Korea; Changhua, Republic of China (Taiwan); Singapore, Singapore) was carried out in order to clarify infection rates with HPV. Samples were examined in one laboratory of the Department of Pathology, the University of Tokyo, Japan in order to avoid inter-laboratory variation using a combination of polymerase chain reaction and in situ hybridization (ISH). HPV was found in 6.3%, 7%, and 9.4% of patients with lung squamous cell carcinoma, lung adenocarcinoma, and esophageal cancer, respectively. Among the geographic areas surveyed, Kagoshima exhibited a significantly higher prevalence of HPV infection in cases of esophageal carcinoma (24.1%). There was no geographical difference in the infection rates of HPV in lung carcinomas. Subtype-specific ISH was also performed, which identified the high-risk HPV types 16/18 in the majority (75.7%) of the patients with lung and esophageal cancer positive for HPV. © 2011 Wiley-Liss, Inc..

We mainly refer to the acute setting of meningococcemia. Meningococcemia is an infection caused by Neisseria meningitidis, which has 13 clinically significant serogroups that are distinguishable by the structure of their capsular polysaccharides. N. meningitidis, also called meningococcus, is a Gram-negative, aerobic, diplococcus bacterium. The various consequences of severe meningococcal sepsis include hypotension, disseminated intravascular coagulation (DIC), multiple organ failure, and osteonecrosis due to DIC. The gold standard for the identification of meningococcal infection is the bacteriologic isolation of N. meningitides from body fluids such as blood, cerebrospinal fluid (CSF), synovial fluid, and pleural fluid. Blood, CSF, and skin biopsy cultures are used for diagnosis. Meningococcal infection is a medical emergency that requires antibiotic therapy and intensive supportive care. Management of the systemic circulation, respiration, and intracranial pressure is vital for improving the prognosis, which has dramatically improved since the wide availability of antibiotics. This review of the literature provides an overview of current concepts on meningococcemia due to N. meningitidis infection. © 2016 The Japanese Society of Internal Medicine. Source

Prion is an infectious particle composed of an abnormal isoform of the prion protein (PrP Sc) and causes prion diseases such as bovine spongiform encephalopathy (BSE), Creutzfeldt-Jakob disease (CJD) and scrapie. Host cells express cellular prion protein (PrP C), which plays roles in normal functions such as anti-oxidative stress. PrP Sc is derived from PrP C and produced by conformational conversion. Prion is notorious as a resistant pathogen, being difficult to inactivate with conventional sterilization procedures. Therefore, to prevent prion-caused iatrogenic diseases, the use of appropriate procedures to inactivate prions is important. For examples, alcohol treatment, autoclave (121°C, 20 min) and γ-ray irradiation, which are used for disinfection, antisepsis or sterilization of viruses and bacteria, are not effective against prion. This is a fundamental review of prions and methods of their inactivation. Source

A 60-year-old man was admitted to our hospital with a tumor in the thoracic esophagus, and squamous cell carcinoma was detected by endoscopic biopsy. On computed tomography, the tumor was suspected of having invaded adjacent organs by so the patient was given neoadjuvant chemotherapy consisting of low-dose CDDP and 5-FU. After 2 courses of chemotherapy, a subtotal esophagectomy was performed. The resected specimen showed no residual squamous cell carcinoma but another tumor was found in the submucosal layer which had a cribiform pattern in a solid nest. The tumor cells were positive for S-100 protein and an Alcian-blue-positive substance in the gland, so the tumor was diagnosed as an adenoid-cystic carcinoma. Source

Purpose: Whether closed tracheal suctioning systems (CTSS) reduce the incidence of ventilator-associated pneumonia (VAP) compared with open tracheal suctioning systems (OTSS) is inconclusive. We conducted a systematic review and meta-analysis of randomized controlled trials that compared CTSS and OTSS.Methods: PubMed, the Cochrane Central Register of Controlled Trials, the Web of Science, Google Scholar, and a clinical trial registry from inception to October 2014 were searched without language restrictions. Randomized controlled trials of CTSS and OTSS that compared VAP in mechanically ventilated adult patients were included. The primary outcome was the incidence of VAP. Secondary outcomes were mortality and length of mechanical ventilation. Data were pooled using the random effects model.Results: Sixteen trials with 1,929 participants were included. Compared with OTSS, CTSS was associated with a reduced incidence of VAP (RR 0.69; 95 % CI 0.54–0.87; Q = 26.14; I2 = 46.4 %). Compared with OTSS, CTSS was not associated with reduction of mortality (RR 0.96; 95 % CI 0.83–1.12; Q = 2.27; I2 = 0.0 %) or reduced length of mechanical ventilation (WMD −0.45 days; 95 % CI −1.25 to 0.36; Q = 6.37; I2 = 5.8 %). Trial sequential analysis suggested a lack of firm evidence for 20 % RR reduction in the incidence of VAP. The limitations of this review included underreporting and low quality of the included trials, as well as variations in study procedures and characteristics.Conclusions: Based on current, albeit limited evidence, it is unlikely that CTSS is inferior to OTSS regarding VAP prevention; however, further trials at low risk of bias are needed to confirm or refute this finding. © 2014, Springer-Verlag Berlin Heidelberg and ESICM.
