SWALLOWING, SPEECH AND OROFACIAL DISORDERS IN CHILDREN WITH ADENOTONSILLAR HYPERTROPHY
2022
A prospective observational study was conducted to evaluate the presence of swallowing, speech and orofacial muscle imbalance (OMI) disorders in patients with adenotonsillar hypertrophy and their regression after surgery. ENT, speech therapist and dentistry examination were conducted before and 12 months after surgery in 78 children between the ages of 2 and 12 with dysphagia, speech disorders and OMI adenotonsillar hypertrophy related with sleep-disordered breathing. Of the 78 patients enrolled, 62 underwent adenotonsillectomy, 9 adenoidectomy and 7 volume reduction of the palatine tonsils with a 12-month post-operative increase in SWAL-QOL score, weight gain, correction of ogival palate, …
Role of β1H for the binding of C3b-coated particles to human lymphoid and phagocytic cells
1981
Coating of EAC14oxy23b with highly purified human serum beta 1H globulin (beta 1H) led to acceleration of rosette formation with human peripheral blood lymphocytes (PBL), tonsil lymphocytes, B lymphoblastoid (Raji) cells, granulocytes and monocytes. This reaction was discernible from C3bi-dependent rosette formation. Enhancement of rosette formation of C3b cells by beta 1H was most effective at limiting amounts of C3 per EAC14oxy23b. The beta 1H effect was not due to trace contamination with C3b inactivator. beta 1H-dependent rosette formation with the various lymphoid and phagocytic cells could be suppressed by the F(ab')2 fragment of anti-beta 1H suggesting beta 1H-mediated binding of bet…
Extramedullary plasmacytoma of the tonsil: A new management
2015
Introduction: Extramedullary plasmacytoma (EMP) is a rare tumor of all plasma cell neoplasms. The tumor is mainly localized in the head and neck region, but rarely involving the tonsil. Case presentation: The authors report the 5th case of EMP of the tonsil in the literature occurred in a 57-year-old Caucasian male. Conclusions: Through a review of the relevant literature, we consider adjuvant radiotherapy not necessary for EMP of tonsil because of an adequate resection achieved by surgery.
In situ transcriptional profile of a germinal center plasmablastic burst hints at MYD88/CD79B mutants-enriched Diffuse Large B-cell Lymphomas
2021
AbstractThe germinal center (GC) reaction results in the selection of B-cells acquiring effector Ig secreting ability by progressing towards plasmablastic differentiation. This transition is associated with exclusion from the GC microenvironment. The aberrant expansion of plasmablastic elements within the GC fringes configures an atypical condition, the biological characteristics of which have not been defined yet. We investigated the in situ immunophenotypical and transcriptional characteristics of a non-clonal germinotropic expansion of plasmablastic elements (GEx) occurring in the tonsil of a young patient. Compared to neighboring GC and peri-follicular regions, the GEx showed a distinct…
Preliminary data revealing efficacy of Streptococcus salivarius K12 (SSK12) in Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adeniti…
2023
ObjectiveTo evaluate the potential role of Streptococcus salivarius K12 (SSK12) in controlling febrile flares in patients with Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis (PFAPA) syndrome. Further aims were to assess the impact of SSK12 on (i) flare duration, (ii) variation in the degree of the highest body temperature during flares, (iii) steroid-sparing effect, and (iv) change of PFAPA accompanying symptoms before and after SSK12 introduction.Patients and methodsThe medical charts from 85 pediatric patients with PFAPA syndrome (49 males and 36 females) enrolled in the AIDA registry and treated with SSK12 for a median period of 6.00 ± 7.00 months in the period b…
Difensil immuno reduces recurrence and severity of tonsillitis in children: A randomized controlled trial
2020
Oral supplements (OS) support the immune system in fighting upper airways infection. This study aimed to analyze the effect of Difensil Immuno (DI) on the recurrence of tonsillitis and fever in children. A multicentric randomized clinical trial was conducted. One-hundred and twenty children with chronic tonsillitis were randomly assigned to group A, B or control. Patients in group A were treated with 10 mL of DI for 90 consecutive days, patients in group B underwent treatment with 15 mL of DI for 45 consecutive days. The following data were collected at baseline (T0), T1 and T2: tonsillitis and fever episodes, tonsillar volume, blood test results. One-way ANOVA was used to analyze within an…
Rapid maxillary expansion and obstructive sleep apnea: a review and meta-analysis
2016
Background: OSAS during childhood leads to significant physical and neuropsychomotor impairment. Thus, it needs to be recognized and treated early in order to avoid or attenuate the chronic problems associated with OSAS, which are deleterious to a child’s development. Adenotonsillectomy and, in select cases, continuous positive airwaypressure (CPAP) have been the preferred treatments for OSAS in children, and yet they are ineffective at fully ameliorating the disease. Minimally invasive treatments have recently been proposed, comprising intra-oral and extra-oral devices as well as speech therapy. Objetive: to conduct a meta-analysis on studies from around the world that used rapid maxillary…
Electron microscopic observation of tonsillar tissue as a diagnostic aid in early juvenile neuronal ceroid-lipofuscinosis.
1987
An electron microscopic observation in a tonsil of a patient with early juvenile neuronal ceroid-lipofuscinosis (NCL) demonstrated characteristic lipopigments in lymphocytes, i.e., fingerprint profiles (FPP) and granular matrixes. While numerous FPP, curvilinear profiles (CLP) and granular matrixes were found in reticulo-endothelial and plasma cells, tonsillar lymphocytes contained only FPP and granular matrixes as seen in circulating lymphocytes. These findings suggest that a tonsil biopsy, an easy and simple technique, may provide more reliable information than a skin biopsy not only for the diagnosis of but also for differentiating the clinical forms of childhood NCL.
Incidence of childhood cancer of the head and neck in Germany.
2007
Background: Only very limited data are available in the literature on the incidence of childhood cancer of the head and neck worldwide. Methods: Based on data obtained from the national German Childhood Cancer Registry, a total of 370 malignancies of the head and neck in children under the age of 15 (199 boys and 171 girls), which were reported to this institution between 1994 and 2003, were analysed in this study. Results: The overall incidence of malignancies of specific sites of the head and neck in Germany is 4.48 per 100000 children. The most frequently observed entities, representing primary tumours, are soft tissue sarcomas (0.39/100000), lymphomas (0.09/100000) and thyroid carcinoma…
Impact of adenotonsillectomy on the evolution of inflammatory markers
2019
Background Tonsils are first-line host defence organs against pathogenic agents and participate in local and systemic immunity. Persistent increases in systemic inflammatory responses may contribute to associated morbidity. The aim of this study was to verify the short- and long-term impact of adenotonsillectomy on the evolution of inflammatory markers in 3- to 9-year-old children. Methods A prospective and longitudinal study was conducted over 1 year in 29 children who underwent tonsillectomy due to either chronic tonsillitis or adenotonsillar hypertrophy. Measurements of high-sensitivity C-reactive protein (hs-CRP) levels were taken. Levels of Th1-type cytokines [interleukin-1, interferon…
