Synchronous Ganglioneuroma and Schwannoma Mistaken for Carotid Body Tumor

Ganglioneuromas are a very rare benign neural tumor, commonly derived from the ganglia of the sympathetic system, and are composed of mature Schwann cells, ganglion cells, and nerve fibres. They may arise anywhere from the base of the skull to the pelvis along the paravertebral sympathetic plexus. We report a rare case of synchronous ganglioneuroma and schwannoma, mistaken for carotid body tumor. The coexistence of these two entities in head and neck region is very rare.

ObjectiveTo describe the endoscopic approach for management of large jaw cysts and assess the feasibility of endoscopic enucleation as well as analyze its outcome on a wide scale at Mansoura University Hospital MUH.MethodsThis prospective cohort study was done on 23 consecutive cases presenting with different types of large jaw cysts in the period from January 2013 to July 2016 at ENT Department, Mansoura University Hospital. All patients, (16 maxillary & 7 mandibular) cysts, were managed endoscopically. Follow up ranged from 6 to 48 months.ResultsAll patients showed complete resolution of their symptoms postoperatively except for 2 maxillary case who didn't undergo an antrostomy and 1 mandibular indicated a second look.ConclusionLarge jaw cysts lie at the border line of management options. Resection of the affected segment is a radical option but the most deforming. On the other hand, conservative procedures are prolonged and not definitive. To our knowledge this is the first case series of endoscopic enucleation of large maxillary and mandibular cysts, highlighting its advantages in variable types.

Autoimmunity occurs in chronic obstructive pulmonary disease (COPD). We describe an antigen microarray for detecting serum autoantibodies (AAbs) to determine how IgM, as well as IgG, AAbs distinguish patients with COPD from controls with a history of smoking without COPD. All COPD patients' sera contained elevated levels of AAbs to some of 30 autoantigens. There were significant differences in the autoantigenic specificities of IgM AAbs compared to IgG AAbs in the COPD sera: for example, AAbs to histone and scl-70 were mainly IgG, whereas AAbs to CENP-B and La/ssB were mainly IgM; by contrast, IgM and IgG AAbs to collagen-V were equally prevalent. Thus, a combination of IgM and IgG AAbs specific for multiple autoantigens are detected in all cases of COPD at a level at which all non-COPD controls are negative for AAbs. This highlights the importance of different classes of AAbs to a range of autoantigens in COPD.

Although autoantibodies have been used for decades as diagnostic and prognostic markers in type 1 diabetes (T1D), further analysis of developmental abnormalities in B cells could reveal tolerance checkpoint defects that could improve individualized therapy. To evaluate B cell developmental progression in T1D, immunophenotyping was used to classify circulating B cells into transitional, mature naïve, mature activated, and resting memory subsets. Then each subset was analyzed for the expression of additional maturation-associated markers. While the frequencies of B cell subsets did not differ significantly between patients and controls, some T1D subjects exhibited reduced proportions of B cells that expressed transmembrane activator and CAML interactor (TACI) and Fas receptor (FasR). Furthermore, some T1D subjects had B cell subsets with lower frequencies of class switching. These results suggest circulating B cells exhibit variable maturation phenotypes in T1D. These phenotypic variations may correlate with differences in B cell selection in individual T1D patients.

ObjectivesSignificant advances in laryngotracheal reconstruction over the last few decades have revolutionised the management of paediatric patients with complex congenital or acquired airway stenosis. The primary aim of laryngotracheal reconstruction has focused primarily on airway and surgery specific outcomes, often at the expense of voice, as well as swallowing function, which are all intricately related. There is currently a paucity of data on swallowing outcome. The goal of this paper is to review and discuss the existing research on the impact of laryngotracheal on swallowing.MethodsNarrative review.ResultsSuccessful and safe oral feeding in children requires a highly complex and integrated sensorimotor system for proper timing and coordination, beginning with a well-coordinated suck-swallow-breathe sequence in infancy. Factors to consider include the normal laryngeal anatomy, nutrition as a stimulus and the development of feeding skills on swallowing, the underlying aetiology and other risk factors, LTR procedures and their adjuncts. All these impact on the children's growth. Swallow assessments and rehabilitation is therefore an important part of the post-operative care.ConclusionsAs airway reconstructive surgeries have improved in airway and surgery specific outcomes, swallowing function is an important secondary outcome that impacts on the children's and their families' life. Management in a multi-disciplinary manner will optimise the outcome and improve their quality of life.

IntroductionThe Sinus and Nasal Quality of Life Survey (SN-5) is a validated quality of life (QOL) questionnaire for chronic rhinosinusitis in patients age 2–12. Its utility in the cystic fibrosis (CF) has been studied, but not yet validated. The purpose of this study is to determine the effectiveness of the SN-5 for evaluation of sinonasal symptoms in the pediatric CF population.MethodsThis retrospective study analyzed SN-5 surveys completed between 2012 and 2015 by pediatric CF patients and caregivers. Baseline and follow-up overall QOL scores and specific symptom scores were obtained from surveys completed in the three-year span. Non-parametric statistics were conducted to identify differences in survey data.ResultsA total of 165 patients completed baseline and follow-up surveys. The overall QOL of the patient cohort did not change over the duration of the study (p = 0.660). Thirty-seven patients indicated higher overall QOL, with all five symptom scores showing significant improvement. Analysis by age group showed that QOL was significantly correlated with all five symptoms for children ages 0–4. In patients 5–12 years, overall QOL was only correlated with sinus infection (r = −0.3090, p = 0.01). QOL was significantly correlated with sinus infection (r = −0.2903, p = 0.04) and allergy symptoms (r = −0.5644, p < 0.01) in patients >12 years of age.ConclusionThere remains a need for a validated CRS QOL tool for children with CF. Though the SN-5 has previously been described as a potential instrument, our data suggest that it may be more valuable in children ages 0–4.
