Migration of alloplastic bone graft material in infected conditions: a case study and animal experiment.

PURPOSE: Distant migration associated with sinus lifting procedures has not been investigated. In the present study, a case of distant migration of graft material was observed, and the potential mechanisms of migration were analyzed using material analysis and in vivo experiments. MATERIALS AND METHODS: The migrated graft material was biphasic calcium phosphate-based alloplastic material (BCP), and its physical properties were compared with those of xenogenic material (Bio-Oss). The comparisons of the physical properties were performed using scanning electronic microscopic, x-ray diffraction,

MEFV, TNF1rA, CARD15 and NLRP3 mutation analysis in PFAPA.

PFAPA is a periodic fever disease, of unknown etiology, characterized by aphthous stomatitis, pharyngitis and cervical adenitis. To inquire whether genes implicated in other auto-inflammatory diseases might be involved in its pathogenesis, predominant mutations in the genes causing familial Mediterranean fever, TNF receptor-associated periodic fever syndrome, Crohn's disease and Muckel-Wells syndrome were analyzed in PFAPA patients. Patients (n = 57) with PFAPA, according to previously published criteria were recruited, at the Meyer Children Hospital during 2006-2007. Clinical information was

[Neck abscess as primary manifestation of head and neck carcinoma: implications for diagnostic management].

BACKGROUND: Neck abscesses and deep neck infections are common diseases in the field of otorhinolaryngology. However, malignant lymph node metastases presenting as abscesses are uncommon and have rarely been described up to now. PATIENTS: A retrospective review between March 1997 and August 1999 was conducted of 40 patients with deep neck abscesses. RESULTS: In five patients (12.5%) the histological diagnostics revealed a malignancy. From these, in 3 cases the cervical abscess was the primary clinical symptom of an oropharyngeal as well as a hypopharyngeal carcinoma. With further 2 patients,

Predilection to Dermato-Lymphangio-Adenitis in Obstructive Lymphedema of Lower Limbs Depending on Genetic Polymorphisms at TNFα-308G>A, CCR2-190G>A, CD14-159C>T, TLR2 2029C>T, TLR4 1063A>G, TLR4 1363C>T, TGFβ 74G>C, and TGFβ 29T>C.

BACKGROUND: Infection is the most common type of complication observed in lymphedema and is promoted by lymphatic system dysfunction, which causes locoregional immune disorders. Infectious complications are primarily bacterial and most commonly cellulitis (dermato-lymphangio-adenitis, DLA) caused by patients' own skin Staphylococci epidermidis and aureus. The clinical course and outcomes in the immune response to infection have been shown to be associated with genetic polymorphisms. AIM: To investigate polymorphism of TNFα-308G>A, CCR2-190G>A, CD14-159C>T, TLR2 2029C>T, TLR4 1063A>G, TLR4 136

The ubiquity of asymptomatic respiratory viral infections in the tonsils and adenoids of children and their impact on airway obstruction.

BACKGROUND: Airway obstruction due to enlargement of tonsils and adenoids is a common pediatric problem resulting in sleep disordered breathing. The cause for the relatively abnormal growth of tonsils and adenoids is poorly understood. METHODS: Non-acutely ill children undergoing tonsillectomy and adenoidectomy (T&A) for various reasons were enrolled prospectively in a study to determine the frequency of asymptomatic respiratory viral infections in each lymphoid tissue and to relate the number and types of virus to the degree of airway obstruction. Molecular techniques were used to detect 9 r

Polyclonal, newly derived T cells with low expression of inhibitory molecule PD-1 in tonsils define the phenotype of lymphocytes in children with Periodic Fever, Aphtous Stomatitis, Pharyngitis and Adenitis (PFAPA) syndrome.

PURPOSE: PFAPA syndrome is a benign, recurrent inflammatory disease of childhood. Tonsillectomy is one of the therapeutic options with a yet unexplained biological mechanism. We tested whether specific lymphocyte subsets recruited from blood to human tonsils participate in PFAPA pathogenesis. METHODS: Paired tonsils/peripheral blood (PB) samples were investigated (a) from children with PFAPA that successfully resolved after tonsillectomy (n=10) (b) from children with obstructive sleep apnoea syndrome as controls (n=10). The lymphocyte profiles were analysed using 8-colour flow cytometry, immu

A taste of periodic fever syndromes.

Periodic fevers are acquired or inherited disorders of innate immunity, which were first described in the 1940s. The patients are typically young at onset and have regularly recurring fevers for a few days to a few weeks with systemic inflammatory symptoms that are interrupted by symptom-free periods. There is a variety of clinical manifestations including gastrointestinal complaints, myalgias, arthralgias, and rash. A differential diagnosis in these patients may include recurrent infections, other inflammatory disorders, and neoplastic disease. This clinical review focuses on a sample of auto

Analysis of rearranged T-cell receptor beta-chain genes by polymerase chain reaction (PCR) DNA sequencing and automated high resolution PCR fragment analysis.

Polymerase chain reaction (PCR)-directed amplification and sequencing of rearranged immune genes for identification of clone-specific markers are increasingly being used in acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL) patients instead of the time consuming and labor intensive Southern analysis. In previous reports, no single common V beta and J beta sequence had been identified that allowed reliable amplification of the majority of rearranged T-cell antigen receptor (TCR)-beta V-D-J junctions at the DNA level because of the relatively large number of possible TCR-beta va

Cervicothoracic lesions in infants and children.

Cervicothoracic lesions are not uncommon in children. All cervicothoracic lesions except superficial lesions extend from the neck to the thorax through the thoracic inlet. Evaluation of this area involves multiple imaging modalities: plain radiography, ultrasonography, nuclear medicine, computed tomography, and magnetic resonance (MR) imaging. However, MR imaging is the method of choice for assessing the full extents of cervicothoracic lesions and their relationships to neurovascular structures. Cervicothoracic lesions can be classified as congenital lesions, inflammatory lesions, benign tumor

The current BCG vaccination program of Japan is critically discussed based on recent knowledge, especially with regard to its epidemiologica … gnificantly against tuberculosis. It is possible, however, that it does protect against tuberculous lymphadenitis. The two above-mentioned possible mechanisms of BCG immunity were applied to a model analysis of BCG revaccination. It was known that revaccination effectiveness is very limited under any assumption, given the current Japanese epidemiological situat …

A dual-mechanism model of Selinexor in DLBCL: p53 reactivation and metabolic reprogramming.

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy with limited therapeutic options in the relapsed or refractory setting. Selinexor, a selective inhibitor of nuclear export targeting XPO1, has demonstrated clinical activity in DLBCL. However, the molecular mechanisms underlying its antitumor effects remain incompletely defined. METHODS: We evaluated the clinical efficacy of Selinexor in a real-world cohort of lymphoma patients and performed integrative transcriptomic and proteomic analyses in DLBCL cell models representing germinal center B-cell–like (GCB) and non-G
