Leuconostoc mesenteroides subsp. strain NTM048 ameliorated nasal symptoms in patients with Japan cedar pollinosis: Randomized, double-blind, and placebo-controlled trial.

Background: Lactobacillales including L mesenteroides have beneficial effects on human health, including improvement of psychological status and alleviation of allergic rhinitis. In mice, L mesenteroides subsp. strain NTM048 (NTM048) increased intestinal s-IgA.

Improvement of Surgical View and Working Space at the Lower Pole by Three-Dimensional Exoscope-Assisted Coblation Tonsillectomy: A Case Series.

Advantages of hot devices for tonsillectomy, represented by coblation, have been highlighted in recent years. During hot technique tonsillectomy it is important to identify and coagulate the vessels of the tonsillar capsule, especially at the lower pole of the tonsil. Hot technique tonsillectomy under microscope or endoscope has therefore been recommended to achieve accurate identification of the microstructure of the surgical field.

Investigation on the virulence of non-encapsulated Streptococcus pneumoniae using liquid agar pneumonia model.

Introduction: Since the introduction of pneumococcal conjugate vaccine, there have been warnings of an increase in infections caused by non-vaccine type of Streptococcus pneumoniae strains. Among them, nonencapsulated Streptococcus pneumoniae (NESp) has been reported to cause invasive infections, especially in children and the elderly. Due to low virulence, however, basic experimental reports on invasive infections are limited.

Lateral approach contributes to shortened surgical time in video-assisted neck surgery (VANS) for thyroid nodule.

Background: Despite endoscopic thyroid surgery contributing to excellent cosmetic outcomes, it requires longer surgical time than open surgery. This study evaluates the factors associated with operative time in video-assisted neck surgery.

Methods: We retrospectively reviewed patients who underwent hemithyroidectomy by video-assisted neck surgery at a single hospital between 2017 and 2021.

Impact of the practical guideline on appropriate usage of antimicrobial treatments for surgical site infections in reconstructive surgery of head and neck cancer.

Objectives: In 2016, Japanese Society of Chemotherapy and Japan Society for Surgical Infection presented the practical guideline for appropriate usage of antimicrobial agents to prevent postoperative infections. This study aims to exhibit the validity of the guideline as a series of effective strategies for prevention of surgical site infections (SSIs) during reconstructive surgery of the head and neck cancer.

Methods: We retrospectively evaluated patients who underwent head and neck reconstructive surgery with free or pedicle flaps in a single institute in Japan between July 2010 and July 2020.

The Roles of Transient Receptor Potential Vanilloid 1 and 4 in Pneumococcal Nasal Colonization and Subsequent Development of Invasive Disease.

Transient receptor potential (TRP) channels, neuronal stimulations widely known to be associated with thermal responses, pain induction, and osmoregulation, have been shown in recent studies to have underlying mechanisms associated with inflammatory responses. The role of TRP channels on inflammatory milieu during bacterial infections has been widely demonstrated. It may vary among types of channels/pathogens, however, and it is not known how TRP channels function during pneumococcal infections.

Improvement in the appropriate antimicrobial usage for treating pediatric acute otitis media in Japan: A descriptive study using nation-wide electronic medical record data.

Objectives: We investigated changes in prescriptions for antimicrobial agents to treat children with acute otitis media (AOM).

Methods: A descriptive study using an electronic medical record database. Of 199,896 patients enrolled between 2001 and 2019, a total of 10,797 were aged <16 years and had AOM as their first and primary disease (overall pediatric AOM cohort).

Pneumococcal capsular phase shift is associated with invasion into cell-to-cell junctions and is inhibited by macrolides.

Streptococcus pneumoniae frequently colonizes the human nasopharynx beginning in the early childhood. Pneumococci exhibit a spontaneous and reversible phase shift between opaque and transparent allowing them to adapt to different environments. This is the first report of the dynamics of pneumococcal phase shift during the course of adhesion and subsequent invasion into epithelial cell monolayers by bacteria-cell co-culture assay with a time-lapse microscopy.

Recurrent bacterial translocation from gut and sepsis in Head and neck cancer patients and its prevention by probiotics.

Head and neck cancers are the 6th most common cancer type in human malignant tumors and treated with chemoradiotherapy and surgery. Chemotherapy during these treatment modalities leads to damage of intestinal epithelial barriers and results in translocation of intestinal bacteria in bloodstream through invasion in these damaged regions. In this report, we report two cases of hypopharyngeal cancer patients, both of whom received chemotherapy before surgery.

A molecular mucosal adjuvant to enhance immunity against pneumococcal infection in the elderly.

Streptococcus pneumoniae (the pneumococcus) causes a major upper respiratory tract infection often leading to severe illness and death in the elderly. Thus, it is important to induce safe and effective mucosal immunity against this pathogen in order to prevent pnuemocaccal infection. However, this is a very difficult task to elicit protective mucosal IgA antibody responses in older individuals.

Genetic characteristics of Haemophilus influenzae and Streptococcus pneumoniae isolated from children with conjunctivitis-otitis media syndrome.

Acute conjunctivitis is the most common ocular disorders among children and frequently concomitant with acute otitis media (AOM) as conjunctivitis-otitis syndrome. In this study, we evaluated prevalence of causative pathogens and PCR-based genotypes of Haemophilus influenzae and Streptococcus pneumoniae among children with conjunctivitis-otitis media syndrome. Nontypeable H.

An application of outer membrane protein p6-specific enzyme-linked immunosorbent assay for detection of haemophilus influenzae in middle ear fluids and nasopharyngeal secretions.

An enzyme-linked immunosorbent assay specific to outer membrane protein P6 (P6-ELISA) was applied for detecting Haemophilus influenzae in middle ear fluids (MEFs) from acute otitis media (AOM) patients and in nasopharyngeal secretions (NPSs) from acute rhinosinusitis patients. P6-ELISA had a sensitivity of 83.3% for MEFs and 71.

Evaluation of a rapid immunochromatographic ODK-0901 test for detection of pneumococcal antigen in middle ear fluids and nasopharyngeal secretions.

Since the incidence of penicillin-resistant Streptococcus pneumoniae has been increasing at an astonishing rate throughout the world, the need for accurate and rapid identification of pneumococci has become increasingly important to determine the appropriate antimicrobial treatment. We have evaluated an immunochromatographic test (ODK-0901) that detects pneumococcal antigens using 264 middle ear fluids (MEFs) and 268 nasopharyngeal secretions (NPSs). A sample was defined to contain S.

Clinical effectiveness of ototopical application of mupirocin ointment in methicillin-resistant Staphylococcus aureus otorrhea.

Objective: Methicillin-resistant Staphylococcus aureus (MRSA) otorrhea has become an increasing problem with regard to infection through the tympanic membrane perforation and postsurgical infection. In particular, dry ear, at the preoperative stage, is considered to be a crucial factor in surgery. We evaluated how to control MRSA otorrhea before and after ear surgery.

[Immuno-histological and-cytological examinations on distribution of newly reported co-stimulatory molecules in germinal center of human tonsils].

Object: Co-stimulatory molecules are important for cell-cell interactions between immune cells, not only for cell activation, but for suppression. Several new co-stimulatory molecules have recently been discovered, and in this study we used immuno-histological and -cytological methods to investigate the distribution of such molecules in the germinal center of human tonsils.

Materials And Methods: Tonsils surgically removed from patients with sleep apnea and habitual tonsillitis were examined.

Genetic dissection of anxiety in autoimmune disease.

Systemic lupus erythematosus (SLE), a complex multigenic disease, is characterized by hypergammaglobulinemia, autoantibody production and immune complex-type lupus nephritis. In addition to these signs and symptoms in SLE, there can be symptoms of neurological disorders, including anxiety. To clarify mechanisms governing the anxiety seen in lupus, we carried out genome-wide scans, and found that the region including interferon-alpha (IFN-alpha) on NZB chromosome 4 is significantly linked to the anxiety-like behavior seen in SLE-prone New Zealand Black (NZB) x New Zealand White (NZW) F(1) (B/W F(1)) mice.
