    Full Text Available Power plant dust is believed to be the main source of the increased presence of the element beryllium in the environment which has been detected in the atmospheric air, surface waters, groundwater, soil, food, and cigarette smoke. In humans, beryllium absorption occurs mainly via the respiratory system. The pharyngeal tonsils are located on the roof of the nasopharynx and are in direct contact with dust particles in inhaled air. As a result, the concentration levels of beryllium in the pharyngeal tonsils are likely to be a good indicator of concentration levels in the air. The presented study had two primary aims: to investigate the beryllium concentration in pharyngeal tonsils in children living in southern Poland, and the appropriate reference range for this element in children’s pharyngeal tonsils. Pharyngeal tonsils were extracted from a total of 379 children (age 2–17 years, mean 6.2 ± 2.7 years living in southern Poland. Tonsil samples were mineralized in a closed cycle in a pressure mineralizer PDS 6, using 65% spectrally pure nitric acid. Beryllium concentration was determined using the ICP-AES method with a Perkin Elmer Optima 5300DVTM. The software Statistica v. 9 was used for the statistical analysis. It was found that girls had a significantly greater beryllium concentration in their pharyngeal tonsils than boys. Beryllium concentration varies greatly, mostly according to the place of residence. Based on the study results, the reference value for beryllium in pharyngeal tonsils of children is recommended to be determined at 0.02–0.04 µg/g.

    Full Text Available Abstract Background Tonsils are secondary lymphoid organs located in the naso- and oropharynx of most mammalian species. Most tonsils are characterised by crypts surrounded by dense lymphoid tissue. However, tonsils without crypts have also been recognised. Gut-associated lymphoid tissue (GALT, although not well-organised and lacking tonsillar crypts, is abundant in the avian oropharynx and has been referred to as the “pharyngeal tonsil”. In this context the pharyngeal folds present in the oropharynx of ratites have erroneously been named the pharyngeal tonsils. This study distinguishes between the different types and arrangements of lymphoid tissue in the pharyngeal region of D. novaehollandiae and S. camelus and demonstrates that both species possess a true pharyngeal tonsil which fits the classical definition of tonsils in mammals. Results The pharyngeal tonsil (Tonsilla pharyngea of D. novaehollandiae was located on the dorsal free surface of the pharyngeal folds and covered by a small caudo-lateral extension of the folds whereas in S. camelus the tonsil was similarly located on the dorsal surface of the pharyngeal folds but was positioned retropharyngeally and encapsulated by loose connective tissue. The pharyngeal tonsil in both species was composed of lymph nodules, inter-nodular lymphoid tissue, mucus glands, crypts and intervening connective tissue septa. In S. camelus a shallow tonsillar sinus was present. Aggregated lymph nodules and inter-nodular lymphoid tissue was associated with the mucus glands on the ventral surface of the pharyngeal folds in both species and represented the Lymphonoduli pharyngeales. Similar lymphoid tissue, but more densely packed and situated directly below the epithelium, was present on the dorsal, free surface of the pharyngeal folds and represented a small, non-follicular tonsil. Conclusions The follicular pharyngeal tonsils in D. novaehollandiae and S. camelus are distinct from the pharyngeal folds in

     Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction.  To verify the correlation between nasopharyngoscopy and cephalometric examinations in the diagnosis of pharyngeal tonsil hyperplasia.  This was a cross-sectional, clinical, experimental, and quantitative study. Fifty-five children took part in this study, 30 girls and 25 boys, aged between 7 and 11 years. The children underwent nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5% significance level was used to verify the correlation between these exams.  In the nasopharyngoscopy evaluation, most children showed grade 2 and 3 hyperplasia of the pharyngeal tonsil, which was followed by grade 1. In the cephalometry assessment, most children showed grade 1 hyperplasia of the pharyngeal tonsil, which was followed by grade 2. A statistically significant regular positive correlation was observed between the exams.  It was concluded that the evaluation of the pharyngeal tonsil hyperplasia could be carried out by fiber optic nasopharyngoscopy and cephalometry, as these examinations were regularly correlated. However, it was found that cephalometry tended to underestimate the size of the pharyngeal tonsil relative to nasopharyngoscopy.

    Full Text Available Background. The aim of the study was to determine the influence of secondary dust and car emission on the intoxication of adenoids. Material and methods. The amount of Pb, Be, Ba, Ca, Mg and Sr in pharyngeal tonsils of children living in Tychy (n 86, and in Chorzów (n 76 as well as the amount of the selected elements in suspended dust was determined by the ICP – AES method. The biological material had previously been subjected to mineralization using of nitric acid (V spectrally pure Merck. Results. Secondary emission as a potential additional source of trace elements in tonsils is described by secondary emission coefficient and by the additional weight of the metal present in general air pollution. Conclusions. The degree of accumulation of analyzed elements in the adenoid tissue mostly depends on the content of these elements in soluble form in suspended dust in the ground layer of air, as a result of secondary and car emissions.

    Full Text Available Introduction: Sinus infections, sore throats, and upper respiratory tract infections (URI are common reasons patients seek medical care. Well-established treatment guidelines exist for prescribing antibiotics in these clinical scenarios, but are not often followed. Objective: The objective of this study is to determine practice patterns related to prescribing antibiotics for sinusitis, URI, and pharyngitis. The main hypothesis is that attending physicians improve their adherence to antibiotic guidelines with a learner present. Methods: A retrospective cohort study was performed on patients treated for URI, sinusitis, and pharyngitis at an ambulatory faculty practice. The use of relevant ICD-9 codes from January 1, 2008 to January 30, 2012 resulted in 1,548 patient encounters which were reviewed for guideline adherence. Univariate analysis and multivariate logistic regression was performed for each outcome variable to determine if they influence antibiotic adherence. Variables studied were physician, presence of a learner, BMI, age, gender, day of the week, month, diabetes, immunosuppression, and COPD. Results: Multivariate analysis showed the statistically significant variables were age (p=0.038 for pharyngitis and provider (p=0.013 for URI. There were no significant findings for sinusitis. Guideline adherence was 24% in patients with pharyngitis, 42% in acute sinusitis, 79% in URI, and 57% overall. Conclusion: Guideline adherence varies depending on the treating physician and decreases when treating younger patients with pharyngitis. The presence of a learner did not improve prescribing habits. The reason for these findings remain unclear, but considerations for improvement could include following antibiotic adherence as a quality measure, giving patients handouts educating them about the impact of overprescribing antibiotics, and further education amongst faculty and residents about adhering to nationally recognized guidelines.

    Full Text Available Introduction: Children with cleft lip and palate (CLP are known to have airway problems. Introduction of ConeBeam CT (CBCT and imaging software has facilitated generation of 3D images for assessing the volume of maxillary sinuses and pharyngeal airway. Consequently, the present study aimed at evaluating and comparing the maxillary sinus and pharyngeal airway volume of patients with cleft lip and palate in healthy patients, using cone beam computed tomography (CBCT images. Materials and method: The sample group included 27 individuals (15 with cleft lip and palate subjects and 12 healthy subjects. The pharyngeal airway and each maxillary sinus were three-dimensionally assessed, segmented and their volume was calculated. A comparison between the right and left sinus was performed by Student t-test, and the differences between the control and cleft groups were calculated using ANOVA. Results: No statistically significant differences were found when the maxillary sinuses volumes from each side were compared (p >0.05. The unilateral CLP patients presented the lowest sinus volume. Individuals with CLP did not exhibit a total airway volume smaller than the nonCLP controls. Conclusions: 3D imaging using CBCT and Romexis software is reliable for assessing maxillary sinus and pharyngeal airway volume. The present study showed that the pharyngeal airway is not compromised in CLP individuals. The unilateral CLP individuals present maxillary sinuses with smaller volumes, no differences being recorded between the cleft and non-cleft side.

    Anatomy, nomenclature, first clinical observations: In ancient Greece and Rome and in the Middle Ages the posterior opening of the nasal passage was known (Greek "choane" = funnel) as an atomical structure, and it was also known that chronic nasal catarrh is common in children, but it was not realized that this was associated with special pathological alterations. The anatomist H. von Luschka in Tübingen, Germany, was the first to describe the nasopharynx in detail, and he coined the term "pharyngeal tonsil." The otologists of the 19th century like Kramer and Toynbee had placed the Eustachian tube in the center of their investigations and carried out numerous dissections with demonstration of the tubal orifice. They also knew that middle ear infections usually originated in the nasopharynx, but they did not realize that the hypertrophic pharyngeal tonsil was the cause. Posterior rhinoscopy and the diagnosis of the hypertrophy of the pharyngeal tonsil: Czermak in Budapest in 1860 had invented posterior rhinoscopy, and he was the first to diagnose hypertrophic alterations around the tubal orifice and the first to realize that they were the cause of tubal malfunction. Wilhelm Meyer in Kopenhagen in 1868 and 1873-1874 described hypertrophy of the pharyngeal tonsil ("adenoid vegetations") in detail and associated this finding with a syndrome characterized by mouth-breathing, snoring, a typical facial expression, deafness, recurring middle-ear affections, and characteristic alterations of speech. He based his conclusions on 5 years' experience with 175 observations in his office and on examination of 2700 children in Denmark and England. Surgical therapy of adenoid vegetations: Voltolini in Breslau in 1865 had observed a few cases of hypertrophy of the pharyngeal tonsil, and he was the first to treat them by galvanic cauterization. Meyer developed various instruments for reducing the pharyngeal tonsil. They were introduced through the nose while the application of the

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

    Full Text Available OBJECTIVES: The aims of this study were to evaluate the correlation between oropharyngeal examination and objective palatine tonsil volume in snoring adults and verify the influence of the oropharyngeal anatomy, body mass index, age, and severity of obstructive sleep apnea on actual tonsil volume. In addition, we aimed to assess the influence of tonsil size on obstructive sleep apnea in adults. INTRODUCTION: Pharyngeal wall geometry is often altered in adults who have obstructive sleep apnea, and this might influence the findings of the oropharyngeal examination that, in turn, are the key factors when considering surgical management for this condition. Furthermore, the correlation between the actual tonsil volume and the severity of obstructive sleep apnea in adults is currently unknown. METHODS: We prospectively studied 130 patients with obstructive sleep apnea or primary snoring who underwent pharyngeal surgery with intraoperative measurement of tonsil volume. We compared tonsil volume with preoperative polysomnography, oropharyngeal examination, and anthropometric data. RESULTS: We found a significant correlation between actual tonsil volume and subjective tonsil grade. We also found a significant correlation between tonsil volume and the apnea-hypopnea index. Using a multivariate linear regression model, tonsil volume was found to be significantly correlated with age, body mass index, and oropharyngeal examination, but not with polysomnography. Clinically, only the rare tonsil grade IV was indicative of more severe obstructive sleep apnea. CONCLUSIONS: There is a strong correlation between clinical tonsil grade and objective tonsil volume in snoring adults, and this correlation exists regardless of the presence or severity of obstructive sleep apnea. Pharyngeal tissue volume likely reflects the body mass index rather than obstructive sleep apnea severity.

  18. Streptococcal acute pharyngitis

    Lais Martins Moreira Anjos

    2014-07-01

    Full Text Available Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine.

    To understand the high incidence of pharyngeal ulcer in patients with acquired immune deficiency syndrome (AIDS). By analyzing the clinical features in AIDS patients with pharyngeal ulcer, this study provided reference for clinicians. Twenty AIDS patients with pharyngeal ulcer were retrospectively analysed to explore its clinical features and mechanism, and to explore the feasible therapeutic methods. The patients generally had severe sore throat and dysphagia for 7 days to 8 months, resulting in significant weight loss. Common therapeutical method does not work. The ulcers developed mainly at vestibule of pharynx (10 cases), tonsil (3 cases), epiglottis (3 cases) and pyriform sinus (2 cases). Ulcer types included major aphthous ulcer (MaAU, 14 cases), fungal ulcer (2 cases), herpes zoster (1 case), ulcer secondary to drug eruption(1 case ), and lymphoma(2 cases). The disease course was long with CD4(+) T lymphocytes decreased significantly. Treatment was given with highly active antiretroviral therapy (HARRT), regulation of immune function, analgesic, anti-inflammatory and anti fungal. Treatment lasted from 2 weeks to 3 months, ulcer healed in 13 cases; 1 patient lost to follow-up, 6 patients dead. The manifestation of pharyngeal ulcer in AIDS patients has its particularity. It is often associated with a variety of opportunistic infection and tumors. Local treatment is preferred. HAART therapy and systemic comprehensive treatment play more important and effective role. Pharyngeal ulcer persists for a long time, complicated with fever, diarrhea and other symptoms. The history of blood transfusion, injection drug use or unsafe sexual behavior may predict HIV infection.

    Full Text Available We examined 1824 patients with diphtheria treated in Clinical Infectious Diseases Hospital Botkin (St. Petersburg in 1993 – 1994, and more than 500 patients referred to the clinic with a diagnosis of «angina». Based on published data and our own research observations investigated the etiology of acute tonsillitis. Bacterial tonsillitis should be treated with antibiotics, and this is important aetiological interpretation of these diseases. Streptococcal tonsillitis should always be a sore throat syndrome as a diagnostic sign of support. For other forms of lymphoma lesion of the tonsils should not be defined as «angina», and called «tonsillitis». Аngina as β-hemolytic streptococcus group A infection is recognized as the leader in the development of rheumatic fever. On the basis of a large clinical material briefly analyzed the clinical manifestations of various forms of diphtheria with membranous tonsillitis.

    Lymphoid organs are supplied by many nerve endings associated with different kinds of cells and macrophages. The role of this innervation on the release of locally active molecules is still unclear. Lingual tonsils belong to Waldeyer's Ring, in close association with palatine tonsils and nasopharyngeal (adenoids) tonsils, thus constituting part of NALT (nasal-associated lymphoid tissue) together with the tubal tonsils and lateral pharyngeal bands. In this study, we focused our attention on the expression of some neurotrophins (NTs) and their high- and low-affinity receptors in human lingual tonsils. Light immunohistochemistry showed that human tonsillar samples were generally positive for all the NTs investigated (NGF, BDNF, NT-3, NT-4) and their receptors (TrKA, TrKB, TrKC and p75) with some different expression levels. NGF and TrKC were strongly expressed in macrophages, but weakly in lymphocytes. However, BDNF and TrKB was highly expressed in lymphocytes and weaker in macrophages. The low-affinity receptor for NGF, p75, was mainly moderately expressed in the analysed samples. These results suggest the presence of a pattern of neurotrophin innervation in the human lingual tonsil which may play a role in sustaining inflammatory conditions and in modulating a close interaction between the nervous system and the different immune cellular subtypes.

    Full Text Available As sinusites, otites médias agudas e tonsilites são muito freqüentes em crianças. A maioria dessas infecções é causada por vírus, mas em geral, elas são tratadas com antibióticos. O uso inapropriado de antibióticos favorece a seleção, crescimento e disseminação de bactérias resistentes que colonizam as vias respiratórias, atingindo toda a comunidade. A emergência de bactérias resistentes dificulta os tratamentos das infecções respiratórias, sendo essencial desenvolver estratégias efetivas para restringir o uso de antibióticos sem prejudicar as crianças que realmente precisam desses medicamentos. OBJETIVO: Analisar os resultados de estudos randomizados e controlados sobre critérios clínicos e laboratoriais utilizados para diagnóstico e tratamento das tonsilites, sinusites e otites. MÉTODOS: Levantamento dos estudos randomizados e controlados sobre o tema, publicados no MEDLINE e SCIELO, de 2000 a 2006. CONCLUSÕES: Como a maioria dessas infecções evolui bem sem antibióticos, deve-se evitar o uso desses medicamentos a menos que a criança pertença aos grupos de alto risco para complicações ou apresente persistência ou piora dos sintomas com tratamento sintomático. É necessário que os médicos e leigos conheçam melhor a evolução natural das infecções respiratórias agudas e que seja garantido o acesso das crianças a serviços médicos de boa qualidade para orientação e reavaliação, quando necessária.Sinusitis, acute otitis media and tonsillitis are very frequent in children.

    Full Text Available Lymphoepithelial cyst (LEC is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.

    Cine MRI has become a useful tool in the evaluation of patients with persistent obstructive sleep apnea (OSA) despite previous surgical intervention and in patients with underlying conditions that render them susceptible to multilevel airway obstruction. Findings on cine MRI studies have also increased our understanding of the mechanisms and anatomic causes of OSA in children. To compare lingual tonsil size between children with OSA and a group of normal controls. In addition, a subanalysis was made of the group of children with OSA comparing lingual tonsils between children with and without underlying Down syndrome. Children with persistent OSA despite previous palatine tonsillectomy and adenoidectomy and controls without OSA underwent MR imaging with sagittal fast spin echo inversion-recovery images, and lingual tonsils were categorized as nonperceptible at imaging or present and measurable. When present, lingual tonsils were measured in the maximum anterior-posterior diameter. If lingual tonsils were greater than 10 mm in diameter and abutting both the posterior border of the tongue and the posterior pharyngeal wall, they were considered markedly enlarged. There were statistically significant differences between the OSA and control groups for the presence vs. nonvisualization of lingual tonsils (OSA 33% vs. control 0%, P=0.0001) and mean diameter of the lingual tonsils (OSA 9.50 mm vs. control 0.0 mm, P=0.00001). Within the OSA group, there were statistically significant differences between children with and without Down syndrome for the three lingual tonsil width categories (P=0.0070) and occurrence of markedly enlarged lingual tonsils (with Down syndrome 35% vs. without Down syndrome 3%, P=0.0035). Enlargement of the lingual tonsils is relatively common in children with persistent obstructive sleep apnea after palatine tonsillectomy and adenoidectomy. This is particularly true in patients with Down syndrome. (orig.)

    Chronic tonsillitis is the persistent inflammation of the tonsillar tissue that occurs due to recurrent, acute or subclinical infection. The recurrent and chronic inflammation of palatine tonsils sometimes results in hypertrophy. Apoptosis provides an important balance between lymphocytes in tonsillar lymphoid tissue. The aim of this study is to investigate the apoptosis in tonsillar diseases. 43 patients with chronic tonsilitis and tonsillar hypertrophy underwent tonsillectomy. The specimens were examined immunohistochemically for apoptosis. Tonsils were assembled into groups according to their size. Specimens were compared for their apoptotic cell count. The apoptosis difference between the tonsil size groups is not statistically significant (p>0.05). However, when the study group was divided into two at age 6, the difference was not statistically significant for patients at and below 6 years of age; but, the difference was statistically significant for patients above 6 years of age (phypertrophy groups revealed no statistical significance (p>0.05). There was a statistically significant positive correlation between intrafollicular and interfollicular, interfollicular and intraepithelial & subepithelial and intraepithelial areas (phypertrophy and atrophy. Apoptosis functioned to balance lymphocyte proliferation in tonsil tissue. The association of apoptosis with tonsillar hypertrophy seemed to be age-dependent. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Introduction: Today bacteriological and patho-anatomical considerations too are taken into account while treating a case of tonsillitis. Past decade has seen the rise of resistance amongst the common pathogens, as well as rise in the number of unusual offenders. Determination of the true offending organism and prescribing an antibiotic as per the sensitivity pattern is of utmost importance.  Materials and Method: A prospective longitudinal study was conducted in a tertiary care hospital in Kolkata. The study population consisted of patients presenting with recurrent attacks of acute tonsillitis. Determination of throat swab micro flora, ASO titre and core tissue microflora was done and correlated statistically. Result: There was poor correlation between throat swab and core tissue microflora. Positive predictive value of throat swab was 10%. Pseudomonas is the predominant flora harbouring tonsillar core in our study population. Amoxicillin the most commonly prescribed antibiotic stands out to be the most resistant one. No statistical significance could be reached comparing streptococcal tonsillitis with ASO titre. Discussion: The real pathology within the tonsil core is not always reflected in routine throat swab and bacteriology of recurrent tonsillitis may differ in different regions. ASO titre estimation adds up to the economic burden if rheumatic fever is not suspected. Judicious use of antibiotics based on true sensitivity pattern is encouraged. In the era of antibiotics Tonsillectomy still holds an important position in the management of recurrent attacks. Conclusion: Pseudomonas was found to be the most common pathogen in recurrent acute tonsillitis. Core tissue study remains the Gold standard in identifying the pathogenic organism. Oral third generation Cephalosporin was the most efficacious antibiotic for recurrent tonsillitis in our study population.

    Surgical quality registers provide tools to measure and improve the outcome of surgery. International register collaboration creates an opportunity to assess and critically evaluate national practices, and increases the size of available datasets. Even though millions of yearly tonsillectomies and tonsillotomies are performed worldwide, clinical practices are variable and inconsistency of evidence regarding the best clinical practice exists. The need for quality improvement actions is evident. We aimed to systematically investigate the existing tonsil surgery quality registers found in the literature, and to provide a thorough presentation of the planned Nordic Tonsil Surgery Register Collaboration. A systematic literature search of MEDLINE and EMBASE databases (from January 2016, to December 2016) was conducted to identify registers, databases, quality improvement programs or comprehensive audit programs addressing tonsil surgery. We identified two active registers and three completed audit programs focusing on tonsil surgery quality registration. Recorded variables were fairly similar, but considerable variation in coverage, number of operations included and length of time period for inclusion was discovered. Considering tonsillectomies and tonsillotomies being among the most commonly performed surgical procedures in otorhinolaryngology, it is surprising that only two active registers could be identified. We present a Nordic Tonsil Surgery Register Collaboration-an international tonsil surgery quality register project aiming to provide accurate benchmarks and enhance the quality of tonsil surgery in Denmark, Finland, Norway and Sweden.

    Lingual tonsils are lymphatic tissues located at the base of the tongue that may hypertrophy causing difficulty and sometimes inability to ventilate or intubate during anesthesia. Routine airway assessment fails to diagnose lingual tonsil hypertrophy. There is limited experience with use of videolaryngoscopy in cases of lingual tonsil hypertrophy. We present a case of difficult airway due to unanticipated lingual tonsil hypertrophy successfully managed by atypical video laryngoscope positioning. Copyright © 2016 Elsevier Inc.

    Full Text Available Introduction Controversy regarding treatment of tonsillitis based on throat culture report still persists. If surface culture is a determinant of bacteriology of the core, then rational therapy could be aimed at organisms cultured by surface swab. Materials and Methods A Cross-sectional study was conducted on 100 patients of chronic tonsillitis who underwent tonsillectomy. Tonsil surface and core swabs were studied for aerobic and anaerobic growth. Result Eighty seven percent patients had aerobic growth on tonsil surface and ninety percent in tonsil core. Staphylococcus aureus was the commonest aerobic bacteria isolated. Anaerobic growth was present in 47% patients on tonsil surface, and 48% in core. Porphyromonas sp. was the commonest anaerobic bacterium isolated. Discussion There was no statistically significant difference between aerobic and anaerobic bacteria found in tonsil surface and core.  Conclusion Throat swabs adequately represent core pathogen, and are dependable in detecting bacteriology of chronic tonsillitis.

    To elucidate the variations of the lateral pharyngeal wall anatomy on physical examination and to assess the clinical importance of the examination of the lateral pharyngeal wall on the presence and severity of obstructive sleep apnoea syndrome. The cross-sectional study was conducted at Ege University Medical School, Izmir, Turkey, between May 2010 and April 2011. The patients were divided into four equal groups: Group 1--snoring without apnoea (age 20-40); Group 2--snoring without apnoea (age 40-60); Group 3--apnoea-hypopnoea index 30/hr. Calibrated oropharynx pictures were taken. Distance between palatoglossal and palatopharyngeal arches, height of palatoglossal and palatopharyngeal arches, uvula width, uvula length and distance between tonsils were measured. SPSS 17 was used for statistical analysis. Of the 80 patients in the study, 44 (55%) were men. Mean distance between palatopharyngeal and palatoglossal arches were 1.55 ± 0.34 cm and 2.70 ± 0.43 cm respectively. Mean height of palatopharyngeal and palatoglossal arches were 0.60 ± 0.21 cm and 1.37 ± 0.36 cm respectively (p > 0.05). Mean uvula width and uvula length were 0.80 ± 0.12cm and 1.25 ± 0.27 cm respectively (p > 0.05). Mean distance between tonsils was 2.24 ± 0.56 cm (p > 0.05). Distance between palatopharyngeal arches was significantly different between groups 3 and 4 (p < 0.05). Palatopharyngeal arch anatomy was found to be significantly associated with obstructive sleep apnoea syndrome severity, especially in patients with normal or small tonsil size. Patients with the palatopharyngeal arches, which narrow the oropharyngeal inlet more than the tonsils, should further be investigated with polysomnography.

  15. Ontogeny of the Middle-Ear Air-Sinus System in Alligator mississippiensis (Archosauria: Crocodylia).

    Dufeau, David L; Witmer, Lawrence M

    2015-01-01

    Modern crocodylians, including Alligator mississippiensis, have a greatly elaborated system of pneumatic sinuses invading the cranium. These sinuses invade nearly all the bones of the chondrocranium and several bony elements of the splanchnocranium, but patterns of postnatal paratympanic sinus development are poorly understood and documented. Much of crocodylomorph--indeed archosaurian--evolution is characterized by the evolution of various paratympanic air sinuses, the homologies of which are poorly understood due in large part to the fact that individual sinuses tend to become confluent in adults, obscuring underlying patterns. This study seeks to explore the ontogeny of these sinuses primarily to clarify the anatomical relations of the individual sinuses before they become confluent and thus to provide the foundation for later studies testing hypotheses of homology across extant and extinct Archosauria. Ontogeny was assessed using computed tomography in a sample of 13 specimens covering an almost 19-fold increase in head size. The paratympanic sinus system comprises two major inflations of evaginated pharyngeal epithelium: the pharyngotympanic sinus, which communicates with the pharynx via the lateral (true) Eustachian tubes and forms the cavum tympanicum proprium, and the median pharyngeal sinus, which communicates with the pharynx via the median pharyngeal tube. Each of these primary inflations gives rise to a number of secondary inflations that further invade the bones of the skull. The primary sinuses and secondary diverticula are well developed in perinatal individuals of Alligator, but during ontogeny the number and relative volumes of the secondary diverticula are reduced. In addition to describing the morphological ontogeny of this sinus system, we provide some preliminary exploratory analyses of sinus function and allometry, rejecting the hypothesis that changes in the volume of the paratympanic sinuses are simply an allometric function of braincase

    Full Text Available ABSTRACT OBJECTIVE To analyze the trend of oral and pharyngeal cancer mortality rates in the period of 2002 to 2013 in Brazil according to sex, anatomical site, and macroregion of the country. METHODS The mortality data were obtained from the Mortality Information System and the population data were obtained from the Brazilian Institute of Geography and Statistics. The trend of the rates standardized by sex and age was calculated using the Prais-Winsten estimation, and we obtained the annual percentage change and the respective 95% confidence intervals, analyzed according to sex, macroregion, and anatomical site. RESULTS The average coefficient of oral cancer mortality was 1.87 per 100,000 inhabitants and it remained stable during the study period. The coefficient of pharyngeal cancer mortality was 2.04 per 100,000 inhabitants and it presented an annual percentage change of -2.6%. Approximately eight in every 10 deaths occurred among men. There was an increase in the rates of oral cancer in the Northeast region (annual percentage change of 6.9% and a decrease in the Southeast region (annual percentage change of -2.9%. Pharyngeal cancer mortality decreased in the Southeast and South regions with annual percentage change of -4.8% and -5.1% respectively. Cancer mortality for tonsil, other major salivary glands, hypopharynx, and other and unspecified parts of mouth and pharynx showed a decreasing trend while the other sites presented stability. CONCLUSIONS Pharyngeal cancer mortality decreased in the period of 2002 to 2013. Oral cancer increased only in the Northeast region.

    Full Text Available Abstract Introduction Cervical necrotizing fasciitis is an aggressive infection with high morbidity and mortality. We present a case of cervical necrotizing fasciitis and descending mediastinitis in a healthy young man, caused by unilateral tonsillitis with a successful outcome without aggressive debridement. Case presentation A 41-year-old man was admitted to our unit with a diagnosis of severe acute unilateral tonsillitis. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. Computed tomography scan of his neck and chest showed evidence of cervical necrotizing fasciitis and descending mediastinitis secondary to underlying pharyngeal disease. He was treated with broad-spectrum intravenous antibiotics. His condition improved over the next 3 days but a tender and fluctuant swelling appeared in the suprasternal region. A repeat scan showed the appearance of an abscess extending from the pretracheal region to the upper mediastinum which was drained through a small transverse anterior neck incision. After surgery, the patient's condition quickly improved and he was discharged on the 18th day of admission. Conclusion Less invasive surgical techniques may replace conventional aggressive debridement as the treatment of choice for cervical necrotizing fasciitis and descending necrotizing mediastinitis.

    Radiofrequency surgery is a widely used modern technique for submucosal volume reduction of the tonsils. So far there is very limited information on morphologic changes in the human tonsils after radiofrequency surgery. We performed histopathological study of tonsillectomy specimens after previous bipolar radiofrequency induced thermotherapy (RFITT). A total of 83 patients underwent bipolar RFITT for hypertrophy of palatine tonsils. Tonsil volume reduction was measured by 3D ultrasonography. Five patients subsequently underwent tonsillectomy. Profound histopathological examination was performed to determine the effect of RFITT on tonsillar architecture. All tonsillectomy specimens showed the intact epithelium, intact germinal centers, normal vascularization, and no evidence of increased fibrosis. No microscopic morphological changes in tonsillectomy specimens after bipolar RFITT were observed. RFITT is an effective submucosal volume reduction procedure for treatment of hypertrophic palatine tonsils with no destructive effect on microscopic tonsillar architecture and hence most probably no functional adverse effect.

    Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome refers to a group of primary immunodeficiencies, namely autoinflammatory diseases. Most pediatricians and otolaryngologists do not suspect PFAPA syndrome when treating recurrent pharyngitis (according to Ukrainian classification - tonsillitis) and stomatitis. Therefore, patients with a given syndrome receive unnecessary treatment (antibiotic therapy or antiviral drugs) and the diagnosis is made late. The aim of the research was to provide pediatricians, family physicians and otolaryngologists with information on the importance of early diagnosis of PFAPA syndrome. The analysis of the prevalence and diagnosis of PFAPA syndrome in Ukraine and worldwide has been made as well as a late diagnosis of PFAPA syndrome in a child living in Ivano-Frankivsk, Ukraine has been described (case report). The Сase report 7-year-old boy, who grows and develops normally. The symptoms of pharyngitis including high body temperature (>40 º С), sore throat and white spots on the tonsils appeared for the first time at the age of two years. The boy received antibacterial drugs about 10 times a year. During a four-year period of recurrent episodes of the disease antimicrobial susceptibility testing to determine susceptibility of the oropharyngeal flora to the antibiotics were continuously performed, different blood tests for herpes viruses, Epstein-Barr virus infection and cytomegalovirus in particular were made using the enzyme immunoassay (EIA) and polymerase chain reaction (PCR) in addition to long-term treatment. An example of late diagnosing PFAPA syndrome (four years after the onset of first symptoms) resulting in regular examinations, medical manoeuvres, outpatient and inpatient treatment, use of antibiotic therapy including intravenous injections on a monthly basis has been studied.

    We studied the usefulness of cephalometry and pharyngeal findings in determining efficient primary diagnosis of obstructive sleep apnea syndrome (OSAS). Subjects were 171 adult men with sleep-disordered breathing, who underwent cephalometry and polysomnography (PSG) and had pharyngeal findings evaluated by modified Mallampati grade (MMP) and palatine tonsil size. An apnea-hypopnea index (AHI) of > or = 15 in PSG was considered to indicate OSAS. We analyzed the correlation between AHI and other parameters and conducted stepwise multiple regression analysis to predict AHI, and studied the screening performance of prediction equations using a receiver operating characteristic (ROC) curve. Of the 8 cephalometric parameters examined, the length of the soft palate (PNS-P; p = 0.011) and the distance from the mandibular plane to the hyoid bone (MP-H; p (a) > (b). Sensitivity and of equation (c) with a cutoff of 15 were 0.95 and specificity 0.25. These results indicate that both cephalometric parameters and pharyngeal indices should be included in conducting an efficient primary diagnosis for OSAS.

    The rectal tonsil is a reactive proliferation of lymphoid tissue located in the rectum. The morphology of the lymphoid proliferation of the colon is usually polypoid or, less commonly, nodular. Only in exceptional cases does lymphoid proliferation of the colon present as a mass in the rectum (rectal tonsil), although this is the most common presentation in middle-aged patients. It is important to be familiar with the rectal tonsil because in cases of exuberant growth it can be difficult to distinguish it from other types of masses. We present the case of rectal tonsil in a four-year-old girl. We describe the magnetic resonance imaging findings and review the literature. Copyright © 2011 SERAM. Published by Elsevier Espana.

    Several pathologies, including pharyngitis, are associated with abdominal pain that can mimic appendicitis. We sought to further understand the link between appendicitis-like symptoms and streptococcal (strep) pharyngitis. All patients undergoing ultrasound imaging for appendicitis in our emergency department during 2013 were reviewed (n = 1572). A total of 207 patients were identified who underwent both ultrasound for appendicitis and testing for strep pharyngitis. Demographic and outcomes data between rule out appendicitis patients who underwent strep testing and those who did not were compared. Strep testing was more common in younger patients (mean age = 8.26 vs 10.26 years P appendicitis and 35 (16.9%) patients tested positive for strep pharyngitis. No cases of concurrent strep pharyngitis and appendicitis were identified. The negative appendectomy rate in the strep pharyngitis tested group was 38.5% (5/13), compared with 7.7% (23/296) ( P = .003) in the nontested group. The appendicitis rate among the strep tested group was 3.8% (8/207) compared with 20% (273/1365) in the nontested group ( P appendicitis, and had a higher rate of negative appendectomy. A diagnosis of concurrent appendicitis and strep pharyngitis is rare. In cases of patients with sufficient symptoms to warrant testing for strep pharyngitis a diagnosis of appendicitis is less likely and surgical intervention leads to higher negative appendectomy rates.

    We have performed a study on 11 human embryos regarding the development of the tympanic ossicles and their relationship with the first pharyngeal arch. After performing measurements to date the embryos and foetuses chronologically, we performed a meticulous dissection of the temporal bones. Subsequently, they were fixed in 10% formol, decalcified with 2% nitric acid, embedded in Paraplast, sectioned in 7-mm sequences and stained with Martin's trichrome technique. In the 21- and 24-mm cranium-raquis (CR) length human embryos, we have observed the head of the malleus and the body of the incus close to Meckel's cartilage, in addition to the handle of the malleus, the long limb of the incus and the stapes. Between them there was a mesenchymal band inside the primordium of the tympanic cavity. In the 27-mm CR embryo, the various components of the malleus and incus were fusing, and in the 30-mm CR embryo the union was complete. From our observations, we can conclude that the malleus and the incus are derived from the first and second pharyngeal arches.

    In clinical F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) studies of the head and neck region, remarkable symmetric tonsillar FDG uptake is sometimes observed. We determined the incidence and degree of tonsillar FDG uptake and investigated the significance of tonsillar FDG uptake. Between June 1998 and August 1998, we obtained informed consent from 17 patients who were scheduled to undergo a FDG-PET study for their own disease (11 men and 6 women; aged 22 to 77 yr) and who did not have head and neck disease to perform FDG-PET scanning of the head and neck region in addition to their target organs. The incidence and degree of tonsillar FDG uptake were determined. Remarkable tonsillar FDG uptake was found in 9 patients. The SUVs of these FDG uptakes ranged from 2.48 to 6.75, with a mean of 4.29±1.20 (SD). Tonsillar FDG uptakes in the remaining 8 patients were not remarkable, and their SUVs ranged from 1.93 to 3.31, with a mean of 2.46±0.45. Head and neck disease does not appear to have been responsible for the increase in tonsillar FDG uptake. Differences among tonsillar FDG uptake in these 17 patients without head and neck disease appear to reflect differences in activity of ''physiological'' inflammation of the palatine tonsils.

    Gastroesophageal reflux is associated with numerous pathologic conditions of the upper aerodigestive tract. Gastric pepsin within reflux contributes to immunologic reactions in the tonsil. In this study, we aimed to find the relationships between pepsin and tonsillar hypertrophy. We explored the notion whether tonsillar hypertrophy was due to pepsin-mediated gastric reflux in tonsil hypertrophy. Fifty-four children with tonsil hypertrophy and 30 adults with tonsillitis were recruited before surgical treatment. Blood and tonsil tissues from each patient were harvested for analysis of changes in lymphocyte and macrophage numbers coupled with histological and biochemical analysis. Pepsin was expressed at different levels in tonsil tissues from each tonsillar hypertrophy. Pepsin-positive cells were found in the crypt epithelium, surrounding the lymphoid follicle with developing fibrosis, and also surrounding the lymphoid follicle that faced the crypt. And also, pepsin staining was well correlated with damaged tonsillar squamous epithelium and TGF-β1 and iNOS expression in the tonsil section. In addition, pepsin and TGF-β1-positive cells were co-localized with CD68-positive cells in the crypt and surrounding germinal centers. In comparison of macrophage responsiveness to pepsin, peripheral blood mononuclear cells (PBMNCs) were noticeably larger in the presence of activated pepsin in the child group. Furthermore, CD11c and CD163-positive cells were significantly increased by activated pepsin. However, this was not seen for the culture of PBMNCs from the adult group. The lymphocytes and monocytes are in a highly proliferative state in the tonsillar hypertrophy and associated with increased expression of pro-inflammatory factors as a result of exposure to stomach reflux pepsin.

    Streptococcus salivarius K12 (BLIS K12) is a probiotic strain strongly antagonistic to the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. Shown to colonize the oral cavity and to be safe for human use, BLIS K12 has previously been reported to reduce pharyngo-tonsillitis episodes in children or adults known to have experienced recurrent streptococcal infection. The present study was focussed upon evaluating the role of BLIS K12 in the control of streptococcal disease and acute otitis media in children attending the first year of kindergarten. By randomization, 222 enrolled children attending the first year of kindergarten were divided into a treated group (N = 111) receiving for 6 months a daily treatment with BLIS K12 (Bactoblis®) and a control group (N = 111) who were monitored as untreated controls. During the 6 months of treatment and 3 months of follow-up, the children were evaluated for treatment tolerance, and for episodes of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media. During the 6-month trial (N = 111 per group) the incidence of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media was approximately 16%, 9% and 44% respectively in the treated group and 48%, 4% and 80% in the control group. During the 3-months follow-up (N = 29 per group) the corresponding rates of infection were 15%, 0% and 12% in the treated group and 26%, 6% and 36% in the controls. No apparent side effects were detected in the treated group either during treatment or follow-up. All of the enrolled children completed the study. The daily administration of BLIS K12 to children attending their first year of kindergarten was associated with a significant reduction in episodes of streptococcal pharyngitis and acute otitis media. No protection against scarlet fever was detected.

    Twenty-six children with obstructive sleep apnea were evaluated by lateral neck radiographs during wakefulness, and by polygraphic monitoring and upper airway fluoreoscopy during natural sleep. Children with craniofacial abnormalities, palatal surgery, and central nervous system disease were excluded from the study. Moderate or marked enlargement of tonsils and adenoids was noted on lateral neck radiographs of 18 of 26 patients. An objective measure of adenoidal enlargement, the adenoidal-nasopharyngeal ratio, correlated well with subjective judgment of adenoidal size but was not generally more useful than subjective estimation. Upper airway fluroescopy demonstrated the site and mechanism of obstruction in all patients. Because all children with moderate to marked adenotonsillar enlargement demonstrated obstruction at the adenoidal or tonsillar level on fluoroscopy, we now screen children with suspected sleep apnea with lateral airway radiographs and polysomnography. Fluoroscopy is reserved for children with mild adenotosillar enlargement, craniofacial dysplasia, prior cleft palate repair, or neuromuscular disorders. These results suggest that the pathogenesis of obstuctive sleep apnea in children involve anatomic factors which narrow the upper airway, sleep-related hypotonia of pharyngeal dilator musculature, and compensatory mechanisms to prevent or alleviate asphyxia.

    The study was conducted to find out the association of various naso-oro-pharyngeal structures with sleep macro-architecture in suspected obstructive sleep apnea subjects. Study included 51 subjects with suspected obstructive sleep apnea. Subjects with possible central apnea and those consuming any substance that can affect sleep architecture were excluded. Level I polysomnography was performed after thorough physical examination. Overnight study was scored in 30 s epochs to find out the polysomnographic variables. Surgical treatment was offered wherever indicated. Subjects with moderate to severe obstructive sleep apnea were manually titrated on CPAP with the polysomnogram. SPSS v 17.0 was used for statistical analysis. We did not find any difference in the sleep architecture between genders. Sleep Efficiency was better in subjects with dental overjet, dental attrition, high tongue base, macroglossia, lesser oral cavity volume, edematous uvula, increased submental fat, hypertrophied facial muscles and Mallampatti grade III-IV. Shorter Sleep Latency was seen in subjects with tender TMJ and Mallampatti Gr III-IV. REM latency was shorter in subjects with high tongue base, macroglossia and hypertrophied muscles of mastication. Increased REM was observed in subjects with high tongue base, edematous uvula and tender TMJ. Enlarged tonsils had reversed effect with poor sleep efficiency, increased REM latency and decreased REM. CPAP therapy (N = 20) lessened awake time, decreased N2 and increased REM. Oro-pharyngeal structures affect the sleep architecture in suspected OSA subjects. Nasal structures do not affect the sleep architecture in these subjects and enlarged tonsils have opposite effect. Sleep architecture changes on the titration night with CPAP.

    Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH. PMID:25548709

    Computational analysis of swallowing mechanics (CASM) is a method that utilizes multivariate shape change analysis to uncover covariant elements of pharyngeal swallowing mechanics associated with impairment using videofluoroscopic swallowing studies. The goals of this preliminary study were to (1) characterize swallowing mechanics underlying stroke-related dysphagia, (2) decipher the impact of left and right hemispheric strokes on pharyngeal swallowing mechanics, and (3) determine pharyngeal swallowing mechanics associated with penetration-aspiration status. Videofluoroscopic swallowing studies of 18 dysphagic patients with hemispheric infarcts and age- and gender-matched controls were selected from well-controlled data sets. Patient data including laterality and penetration-aspiration status were collected. Coordinates mapping muscle group action during swallowing were collected from videos. Multivariate morphometric analyses of coordinates associated with stroke, affected hemisphere, and penetration-aspiration status were performed. Pharyngeal swallowing mechanics differed significantly in the following comparisons: stroke versus controls (D = 2.19, P mechanics associated with each comparison were visualized using eigenvectors. Whereas current literature focuses on timing changes in stroke-related dysphagia, these data suggest that mechanical changes are also functionally important. Pharyngeal swallowing mechanics differed by the affected hemisphere and the penetration-aspiration status. CASM can be used to identify patient-specific swallowing impairment associated with stroke injury that could help guide rehabilitation strategies to improve swallowing outcomes.

    The syndrome of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) is an autoinflammatory disorder of unknown aetiology. Tonsillectomy may cause a prompt resolution of the syndrome. The aim was to study the histologic and immunological aspects of the palatine tonsils in PFAPA, to help understand the pathophysiology of the syndrome. Tonsils from children with PFAPA (n = 11) and children with tonsillar hypertrophy (n = 16) were evaluated histologically after haematoxylin and eosin staining. The number of different cell types was identified immunohistochemically by cluster of differentiation (CD) markers: CD3 (T cells), CD4 (T helper cells), CD8 (cytotoxic T cells), CD15 (neutrophils), CD20 (B cells), CD45 (all leucocytes), CD57 (NK cells) and CD163 (monocytes and macrophages). Tonsils from children with PFAPA showed reactive lymphoid hyperplasia dominated by well-developed germinal centres with many tingible body macrophages. The histologic findings were unspecific, and a similar morphologic appearance was also found in the tonsils from controls. The number of CD8+ cells in germinal centres differed between children with PFAPA [median 9 cells (quartiles: 5, 15)] and controls [18 cells (12, 33) (P = 0.001)] and between children with PFAPA with (median 14 cells; 9, 16) and without (4 cells; 3, 8) aphthous stomatitis (P = 0.015). For the other cell types, no differences in germinal centres were found between children with PFAPA and controls. In conclusion, a lower number of CD8+ cells were found in germinal centres of tonsils in children with PFAPA compared to controls, which may be a feature linked to the aetiology of the syndrome. © 2015 John Wiley & Sons Ltd.

    Full Text Available Treatment of dentofacial deformities with jaw osteotomies has an effect on airway anatomy and therefore mandibular setback surgery has the potential to diminish airway size. The purpose of this study was to evaluate the effect of mandibular setback surgery on airway size. 8 consecutive patients were examined prospectively. All patients underwent mandibular setback surgery. Cephalometric analysis was performed preoperatively and 3 months post operatively with particular attention to pharyngeal airway changes. Pharyngeal airway size decreased considerably in all, patients thus predisposing to development of obstructive sleep apnea. Therefore, large anteroposterior discrepancies should be corrected by combined maxillary and mandibular osteotomies.

    Allergic fungal sinusitis is a recently described clinical entity that has gained increased attention as a cause of chronic sinusitis. Consist in a benign noninvasive sinus disease related to a hypersensitivity reaction to fungal antigens. It should be suspected in any atopic patient with refractory nasal polyps. Computed tomography (CT) findings are characteristics, but not diagnostic. Diagnosis requires show allergic mucin in the histopathologic examination and hiphae in special fungal stains. The suitable treatment includes the allergic mucin removal and sinus aeration accomplished endoscopically, perioperative systemic steroids and immunotherapy with fungal antigens. We present a case of this kind of chronic sinusitis describing the characteristic histopathologic and radiologic findings, the pathogenic theories and recent advances in immunotherapy.

    To describes how tonsil surgery was performed in Sweden from 2013 to 2015 with data from the National Tonsil Surgery Registry in Sweden (NTSRS). The registry collects data from both professionals and patients through questionnaires. A total of 33,870 tonsil surgeries were analysed, comprising approximately 80% of all tonsil surgeries in Sweden from 2013 to 2015. The two most common procedures were tonsillectomy (41%) and tonsillotomy with adenoidectomy (38%). Tonsillectomy was most commonly performed to treat frequent tonsillitis, while the main indication for tonsil surgery with combined adenoidectomy and for tonsillotomy alone was upper airway obstruction. The most commonly used techniques were cold steel (70%) for tonsillectomy/adenotonsillectomy and radiofrequency (79%) for tonsillotomy/adenotonsillotomy. Ninety-five percent of patients reported symptom relief after 180 d. Day surgery was utilised in 70% of the surgeries. The rate of readmission due to post-tonsillectomy haemorrhage was 5.1%. Male patients more often underwent tonsil surgery at preschool ages due to upper airway obstruction; in comparison, female patients to a larger extent underwent surgery in their early teens because of previous infections. The NTSRS provides an opportunity to survey tonsil surgery in Sweden and to launch and follow up improvement programmes as desired.

    Full Text Available Interest in the mechanisms and causes of recurrent tonsillitis is considerable. CD4+CD25+ T-lymphocytes have an important role in the maintenance of immunological tolerance. The aim of our research was to compare the diagnostic value of palatine tonsils histological and microbiological screening in patients with hypertrophic and recurrent tonsillitis. 14 patients with hypertrophic and 10 patients with chronic tonsillitis undergoing tonsillectomy were enrolled in the study. Rapid diagnosis of adenovirus, parainfluenza, influenza A and B, and respiratory syncytial virus infection was made before tonsillectomy by viral antigen detection using the immunofluorescence procedure from tonsils. Herpes simplex and cytomegaloviruses DNA were detected by the polymerase chain reaction. Samples for bacteriological studies were collected using a cotton swab. Immunohistochemical methods were used to evaluate S-100 and TGF-beta1 expression. The obtained results showed that patients with recurrent tonsillitis had less S-100 and TGF-beta1 positive cells in parafollicular regions compared to patients with hypertrophic tonsillitis. In both groups, tonsils were colonized predominantly by gram-positive microorganisms and adenovirus (36% of cases. However, in patients with recurrent tonsillitis, associations of gram-positive, gram-negative bacteria and viruses (40% of cases were observed. To conclude, recurrent tonsillitis is characterized by the breakdown of the immunological tolerance to oral microflora.

    Full Text Available Complex research of rheological properties of blood at patients with lacunar tonsillitis lead depending on the period of disease. It is shown, that inflammatory process at patients to a great extent defines disturbances of rheological properties of blood. During normalization of a clinical presentation of disease there is no full recovery of rheological properties of blood due to preservation of blood raised viscosity and low deformability of erythrocytes membranes.

    Full Text Available The Polyomaviruses KI and WU have been identified in 2007 in nasopharyngeal aspirates of patients with acute respiratory tract infections.They have been further isolated in faecal samples, lymphoid tissue, bronchoalveolar lavages and blood, although their pathological associations, molecular epidemiology and tissue tropism are still not widely known.The aim of this study was to determine the presence of KIV and WUV in tonsillar tissue of immunocompetent patients to assess whether the tonsils may represent a site of infection and/or persistence.The presence of Polyomavirus BKV, JCV and SV40 was also evaluated. The presence of Polyomavirus KI,WU, BK, JC and SV40-DNA was evaluated in a prospective study on tonsillar samples obtained from 29 immunocompetent patients (adults and children undergoing tonsillectomy by a commercially available Taqman Real-time quantitative PCR (BKV Q-PCR Alert Kit, Nanogen and a home-made system (for KIV,WUV, SV40, JCV.The amplification conditions were optimized and standardized. KIV-DNA was detected in 2/29 (6.9% tonsil tissue (obtained from an adult and a child, while WU, BK, JC and SV40 were negative in all cases. Our prevalence results are consistent with those reported in the literature on samples from the respiratory tract and lymphoid tissue such as tonsils. Further studies are needed to understand the significance of the presence of KIV in tonsil tissue and assess the possibility that the virus can establish latent and/or persistent infection at this level.

    Purpose: To assess, through a retrospective review, clinical outcomes of patients with squamous cell carcinoma of the tonsil treated at the M. D. Anderson Cancer Center with unilateral radiotherapy techniques that irradiate the involved tonsil region and ipsilateral neck only. Methods and Materials: Of 901 patients with newly diagnosed squamous cell carcinoma of the tonsil treated with radiotherapy at our institution, we identified 102 that were treated using unilateral radiotherapy techniques. All patients had their primary site of disease restricted to the tonsillar fossa or anterior pillar, with <1 cm involvement of the soft palate. Patients had TX (n = 17 patients), T1 (n = 52), or T2 (n = 33) disease, with Nx (n = 3), N0 (n = 33), N1 (n = 23), N2a (n = 21), or N2b (n = 22) neck disease. Results: Sixty-one patients (60%) underwent diagnostic tonsillectomy before radiotherapy. Twenty-seven patients (26%) underwent excision of a cervical lymph node or neck dissection before radiotherapy. Median follow-up for surviving patients was 38 months. Locoregional control at the primary site and ipsilateral neck was 100%. Two patients experienced contralateral nodal recurrence (2%). The 5-year overall survival and disease-free survival rates were 95% and 96%, respectively. The 5-year freedom from contralateral nodal recurrence rate was 96%. Nine patients required feeding tubes during therapy. Of the 2 patients with contralateral recurrence, 1 experienced an isolated neck recurrence and was salvaged with contralateral neck dissection only and remains alive and free of disease. The other patient presented with a contralateral base of tongue tumor and involved cervical lymph node, which may have represented a second primary tumor, and died of disease. Conclusions: Unilateral radiotherapy for patients with TX-T2, N0-N2b primary tonsil carcinoma results in high rates of disease control, with low rates of contralateral nodal failure and a low incidence of acute toxicity

  4. The localization of the larvae of the nostril fly (Cephenemyia trompe L in the pharynx of reindeer in an earlier unknown tonsil tissue

    Full Text Available The localization of the larvae of the reindeer nostril fly (Cephenemyia trompe L in the pharynx was investigated in 21 reindeer, 11 months old, during April, and in 5 animals during November. In reindeer, without the presence of larvae, no preformed pharyngeal pouch was found at the predilection site, dorsomedially in the pharynx, but an unpaired tronsil, tentatively named Tonsilla pharyngis dorso-medialis. In 12 of the animals investigated during April, a puch containing larvae of C. trompe was found at the predilection site, i.e. the site of the dorsomedially located tonsil. Histologically remnants of tonsil tissue was present at the opening of the pouch. In 3 animals a pouch, containing larvae, was found in the left lateral wall and in 2 animals in the right lateral wall of the pharynz between the opening of Tuba auditiva and the tonsil. In one animal 2 pouches were found, one in the tonsil tissue and one located in the right lateral wall of pharynx. In serial sections from two animals investigated during November, 1 :st instar larvae of Cephenomyia trompe were found in the crypts of the tonsills. The fact that the tonsil tissue is a predilection site for C. trompe larvae may be due to the mechanical protection the 1st instar larvae can find in the crypts. Larvae may, however, also attach to other parts of the pharyngeal mucosa. During their development the larvae penetrate the mucosa forming a pouch. The wall of this pouch consists of a naked acute granulation tissue heavily infiltrated with eosinophilic leucocytes. In connection with the healing process, starting when the larvae have left, a pouch may remain, characterized by walls of chronic granulation tissue covered by a mucous membrane. This pouch could well be misinterpreted as a preformed pouch.Lokalisationen av svalgkormflugans (Cephenemyia trompe L larver i svalget på ren i en tidigare okänd tonsillvävnad (Tonsilla pharyngis dorso-medialis.Abstract in Swedish / Sammanfattning

    Full Text Available Aim: Helicobacter pylori is the major gastric pathogen which has an important role in the etiopathogenesis of chronic gastritis. We investigated the presence of Helicobacter pylori as an extragastric reservoir in the tonsillectomy specimens to display if it is an etiologic factor in the development of chronic tonsilitis. Material and Method: In the current study, 100 cases with chronic tonsilitis were examined in bilateral tonsillectomy specimens. The colonization of the microorganism have been evaluated with hematoxylin-eosin and giemsa stains under the light microscope.Results: Helicobacter pylori has been detected in 33 cases (33% on one side of the bilateral tonsillectomy specimens while it has been seen in 15 cases (15% on both sides which demonstrated positivity in 48 cases (48% in total. No colonization has been observed in the remaining 52 cases (52%. Discussion: Due to the considerable positivity in our study, the histopathologic evaluation of tonsillary Helicobacter pylori colonization may be instrumental in the etiologic association with chronic tonsillitis.

    Dysphagia (impaired swallowing) is common in patients with Parkinson disease (PD) and is related to aspiration pneumonia, the primary cause of death in PD. Therapies that ameliorate the limb motor symptoms of PD are ineffective for dysphagia. This suggests that the pathophysiology of PD dysphagia may differ from that affecting limb muscles, but little is known about potential neuromuscular abnormalities in the swallowing muscles in PD. This study examined the fiber histochemistry of pharyngeal constrictor and cricopharyngeal sphincter muscles in postmortem specimens from 8 subjects with PD and 4 age-matched control subjects. Pharyngeal muscles in subjects with PD exhibited many atrophic fibers, fiber type grouping, and fast-to-slow myosin heavy chain transformation. These alterations indicate that the pharyngeal muscles experienced neural degeneration and regeneration over the course of PD. Notably, subjects with PD with dysphagia had a higher percentage of atrophic myofibers versus with those without dysphagia and controls. The fast-to-slow fiber-type transition is consistent with abnormalities in swallowing, slow movement of food, and increased tone in the cricopharyngeal sphincter in subjects with PD. The alterations in the pharyngeal muscles may play a pathogenic role in the development of dysphagia in subjects with PD.

    The aim of this study is to look into the roles of iron and zinc metals in etiopathogenesis of recurrent tonsillitis and tonsillar hypertrophy by evaluating the levels of iron and zinc elements in the palatine tonsillar tissue. In total, 40 patients who underwent a tonsillectomy to treat recurrent tonsillitis and tonsillar hypertrophy were included in the study. Patients were classified into two groups, recurrent tonsillitis and tonsillar hypertrophy, determined by the results of clinical and histopathological examination. The levels of iron and zinc elements were determined for each tonsillar tissue sample. There was a significant difference in the iron and zinc concentrations (phypertrophy and recurrent tonsillitis groups. The levels of iron and zinc were significantly lower in the recurrent tonsillitis group. This study suggests that low tissue concentrations of iron and zinc may lead to recurrent tonsillitis.

    2013-02-01

    This study aimed to evaluate the palatine tonsils of patients with chronic tonsillitis and spinocellular carcinoma to determine the presence of nano-sized particles. Tonsil samples from adult patients with chronic tonsillitis and spinocellular carcinoma of the palatine tonsil were dried and analyzed using a scanning electron microscope with the X-ray microprobe of an energy-dispersive spectroscope. Demographic data and smoking histories were obtained. The principal metals found in almost all tissues analyzed were iron, chromium, nickel, aluminum, zinc, and copper. No significant difference in elemental composition was found between the group of patients with chronic tonsillitis and the group with spinocellular carcinoma of the palatine tonsil. Likewise, no significant difference was found between the group of smokers and the group of nonsmokers. The presence of various micro- and nano-sized metallic particles in human tonsils was confirmed. These particles may potentially cause an inflammatory response as well as neoplastic changes in human palatine tonsils similar to those occurring in the lungs. Further and more detailed studies addressing this issue, including studies designed to determine the chemical form of the metals detected, studies devoted to quantitative analysis, biokinetics, and to the degradation and elimination of nanoparticles are needed for a more detailed prediction of the relation between the diagnosis and the presence of specific metal nanoparticles in tonsillar tissue.

    An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case. (orig.)

    An encephalocele is a protrusion of the cranial contents beyond the normal confines of the skull. It is a rare cause of seizure in adults. A 38-year-old woman presented with a first-onset seizure. Brain CT was interpreted as right frontal sinus opacification suggestive of sinusitis. The patient was discharged home with an amoxicillin prescription. A few days later, she was re-admitted with another seizure. Careful evaluation of the brain CT and MRI revealed a right frontal sinus posterior wall defect and possible brain encephalocele. The patient had complained of chronic nasal discharge for years and had also noticed a watery discharge from her right nostril. We suspected cerebrospinal fluid rhinorrhea. A bifrontal craniotomy was performed, the encephalocele was resected and cranialisation of the frontal sinus was completed. The patient remained free of seizures at the last follow-up. PMID:23188840

    We evaluated the effectiveness and safety of ipsilateral radiotherapy for the patient with well lateralized tonsil cancer: not cross midline and <1 cm of tumor invasion into the soft palate or base of tongue. From 2003 to 2011, twenty patients with well lateralized tonsil cancer underwent ipsilateral radiotherapy. Nineteen patients had T1-T2 tumors, and one patient had T3 tumor; twelve patients had N0-N2a disease and eight patients had N2b disease. Primary surgery followed by radiotherapy was performed in fourteen patients: four of these patients received chemotherapy. Four patients underwent induction chemotherapy followed by concurrent chemoradiotherapy (CCRT). The remaining two patients received induction chemotherapy followed by radiotherapy and definitive CCRT, respectively. No patient underwent radiotherapy alone. We analyzed the pattern of failure and complications. The median follow-up time was 64 months (range, 11 to 106 months) for surviving patients. One patient had local failure at tumor bed. There was no regional failure in contralateral neck, even in N2b disease. At five-year, local progression-free survival, distant metastasis-free survival, and progression-free survival rates were 95%, 100%, and 95%, respectively. One patient with treatment failure died, and the five-year overall survival rate was 95%. Radiation Therapy Oncology Group grade 2 xerostomia was found in one patient at least 6 months after the completion of radiotherapy. Ipsilateral radiotherapy is a reasonable treatment option for well lateralized tonsil cancer. Low rate of chronic xerostomia can be expected by sparing contralateral major salivary glands.

    Full Text Available Pulmonary renal syndrome is a class of small vessel vasculitides that are characterized by the dual presentation of diffuse alveolar hemorrhage (DAH and glomerulonephritis. Pulmonary renal syndrome has multiple etiologies, but its development has been rarely reported following infection with group A streptococcus. We present the case of a 36-year-old Native American male who was transferred to our facility due to refractory hypoxic respiratory failure. He had been diagnosed with streptococcal pharyngitis 2 weeks prior to admission. Given the presence of hemoptysis, bronchoscopy was performed and was consistent with DAH. Urinalysis demonstrated hematuria and proteinuria, in the setting of elevated creatinine and blood urea nitrogen. Additionally, antistreptolysin O titer was positive. Given the constellation of laboratory findings and history of streptococcal pharyngitis, the patient was diagnosed with PRS secondary to streptococcal infection. High-dose methylprednisolone was initiated with concomitant plasmapheresis. He was extubated successfully after his respiratory status improved and was eventually discharged home after making a full recovery within 2 weeks after admission. This case illustrates the importance of clinically relevant sequelae of streptococcal infection as well as the appropriate treatment of PRS secondary to streptococcal pharyngitis with plasmapheresis and intravenous corticosteroids.

    The purpose of this study was to investigate the effects of tonsil-derived mesenchymal stem cells (MSCs) on osteoradionecrosis (ORN). We generated a mandibular ORN rat model using a combination of 20-Gy single-dose irradiation and tooth extraction. Study groups were negative control (tooth extraction only), ORN group (irradiation, tooth extraction), Matrigel-1 group (Matrigel; BD Biosciences, San Jose, CA; irradiation, Matrigel application immediately after tooth extraction), tonsil-derived MSC-1 group (irradiation, tonsil-derived MSC application immediately after tooth extraction), Matrigel-4 group (irradiation, Matrigel application 4 weeks after tooth extraction), and tonsil-derived MSC-4 group (irradiation, tonsil-derived MSC application 4 weeks after tooth extraction). Bone mineral density was significantly lower in the ORN group than in the negative control group. The tonsil-derived MSC-1 group showed significantly higher bone mineral density than did the ORN and tonsil-derived MSC-4 groups. A single 20-Gy dose of irradiation combined with tooth extraction successfully generated ORN in the rat model. The tonsil-derived MSCs can be effective for bone regeneration in ORN, particularly when applied immediately after dentoalveolar trauma or surgery. © 2017 Wiley Periodicals, Inc.

    1991-01-01

    Ah receptor was identified and characterized in cytosol and nuclear extracts from human tonsils obtained at surgery from children 2 to 6 years of age. Ah receptor was found in cytosol prepared from whole-tonsil homogenates as well as in cytosol and nuclear fractions prepared from tonsil lymphocytes or tonsil fibroblasts grown in primary culture. Cytosolic Ah receptor was detectable in tonsillar tissue with either halogenated (2,3,7,8-[3H]tetrachlorodibenzo-p-dioxin (TCDD)) or nonhalogenated (3-[3H]methylcholanthrene and [3H]benzo[a]pyrene) aromatic hydrocarbons and sedimented at approximately 9 S after velocity sedimentation on sucrose gradients. The apparent binding affinity (Kd) of [3H]TCDD for Ah receptor ranged from 3 to 12 nM in cytosols from seven different donors. The same analyses indicated a concentration of Ah receptor in human tonsils of approximately 100-300 fmol/mg cytosolic protein. Incubation of either tonsil lymphocytes or tonsil fibroblasts with [3H]TCDD resulted in transformation of cytosolic Ah receptor to a nuclear binding form which could be detected as a specifically labeled peak sedimenting at approximately 6 S on sucrose gradients. These data demonstrate the existence of Ah receptor in human tonsils and suggest that this immune organ may be an appropriate model for further studies on the mechanism and manifestation of aromatic hydrocarbon-induced immunotoxicity in man

  15. Maxillary sinus augmentation

    Full Text Available Placing dental implants in the maxillary posterior region can be both challenging and un-nerving for a regular implant dentist who is not well versed with advanced surgical procedures. It is vital for a general dentist to understand the fundamentals of bone grafting the maxillary sinus if he/she is really committed to providing the best health care for their patients. The dental practice is seeing an increasing group of patients who are living longer, and this group of older baby boomers often has an edentulous posterior maxilla either unilateral or bilateral. When edentulous, the posterior maxilla more likely has diminished bone height, which does not allow for the placement of dental implants without creating additional bone. Through grafting the maxillary sinus, bone of ideal quality can be created (allowing for placement of dental implants, which offer many advantages over other tooth replacement modalities. The sinus graft offers the dental patient a predictable procedure of regenerating lost osseous structure in the posterior maxilla. This offers the patient many advantages for long-term success. If dentists understand these concepts, they can better educate their patients and guide them to have the procedure performed. This article outlines bone grafting of the maxillary sinus for the purpose of placing dental implants. This review will help the readers to understand the intricacies of sinus augmentation. They can relate their patient's condition with the available literature and chalk out the best treatment plan for the patient, especially by using indirect sinus augmentation procedures which are less invasive and highly successful if done using prescribed technique.

  16. MRI of maxillary sinuses

    1993-01-01

    A mucous membrane of the maxillary sinus is clinically important in the dental fields. Magnetic resonance imaging (MRI) can demonstrate a mucous membrane because the mucosa contains rich free water. However, the morphology and location of the mucous membrane of normal maxillary sinuses have not been studied well by MRI. T2-weighted coronal images were obtained by spin echo technique in 40 normal volunteers. The eight maxillary sinuses were classified into four groups (Type 1∼IV) according to the morphology and also classified into five groups (Type a, b1, b2, b3, c) according to the location of the mucous membrane. Coronal images obtained at a standard angle of 77 degree to the Frankfort horizontal (FH) plane was the best for the evaluation of maxillary sinus because the image displayed the maximum cross-section of the maxillary sinus. In the normal cases, Type I (no high signal intensity) was observed in 20 sites, Type II (linear high signal intensity) in 48 sites, Type III (belt-like high signal intensity) in 11 sites and Type IV (mass-like high signal intensity) in 1 site. Type a (medial∼basal wall) was observed in 46 sites, Type b1 (medial wall alone) in 4 sites, Type b2 (basal wall alone) in 8 sites and Type c (entire wall) in 2 sites. Half of the cases showed the same findings bilaterally. Thus, MRI could demonstrate the morphology and location of the mucous membrane in the normal maxillary sinus so clearly that MRI was considered to be a useful diagnostic tool in the dento-maxillo-facial region.

    Purpose: Denervation of the carotid sinus causes baroreflex and chemoreflex failure, resulting in labile hypertension and loss of hypoxic responsiveness. We investigated whether radiation therapy for laryngeal or pharyngeal cancer affects baroreflex and chemoreflex function. Methods and Materials: Twelve patients were studied after radiation therapy for locally advanced laryngeal or pharyngeal cancer (11 male, 1 female, age: 56.0 ± 7.9 years), 3.3 years (median; range 1.0-4.7) after radiotherapy and 15 healthy controls (11 male, 4 female, 53.4 ± 9.2 years). We measured baroreflex sensitivity (phenylephrine), blood pressure level and variability (24-h Spacelabs and 5-h Portapres recordings), responses to cardiovascular reflex tests, and the ventilatory responses to normocapnic and hypercapnic hypoxia. Results: Baroreflex sensitivity was lower in patients (9.7 ± 7.8 ms/mm Hg) than in controls (17.5 ± 10.3 ms/mm Hg, p=0.011). Mean office blood pressure was significantly higher in patients (141.5 ± 27.8/89.2 ± 10.6 mm Hg, 63.3 ± 12.3 bpm) than in controls (117.3 ± 10.1/75.1 ± 6.8 mm Hg, 61.8 ± 10.8 bpm). Blood pressure variability was not different between groups, nor were the responses to reflex tests. The normo/hypercapnic ventilatory response to hypoxia was similar in patients (0.21 ± 0.10/1.37 ± 0.60 L/min/%) and controls (0.22 ± 0.16/1.19 ± 0.78 L/min/%). Conclusions: Radiation therapy for laryngeal or pharyngeal carcinoma does not affect chemoreflex function, but results in an attenuated baroreflex sensitivity. Clinically relevant blood pressure lability is absent however

    Full Text Available The article presents basic features of the mineral metabolism in adolescent children suffering from chronic tonsillitis and secondary affection of the cardiovascular system in disease dynamics. Aim of this work was to study the dynamics of zinc, iron, potassium and magnesium in adolescents with disorders of the cardiovascular system and chronic tonsillitis. Materials and methods. 63 patients with chronic tonsillitis were examined, among them – 31 children suffered from chronic tonsillitis without pathology of the cardiovascular system (I group, 32 – were patients with disorders of the cardiovascular system on the background of chronic tonsillitis (II group. Determination of concentration of trace elements of iron, zinc, potassium, magnesium in blood serum was measured by atomic absorption spectrophotometry. Results. The content of trace elements zinc, iron, minerals potassium and magnesium was analyzed. It breaches of macro- and trace element composition in the blood serum of children with chronic tonsillitis in the form of lower concentrations of iron and zinc in patients with damage to the cardiovascular system, and in patients without cardiac disease. It should be noted that children with tonsillogenyc cardiac lesions had a significant decrease in the level of macro-magnesium during hospitalization compared to children without cardiovascular pathology. After treatment, levels of such elements as iron, zinc, magnesium were not normalized. Moreover, significant changes were observed in patients with heart disease on the background of chronic tonsillitis. After the standard treatment, concentrations of iron and zinc in both groups, and magnesium in children from the second group remained at a low level, compaed with children without cardiac disease. Conclusion. The analysis of micro and macro elements in the serum of children with chronic tonsillitis, showed a significant decrease of iron and zinc concentration in the first days of

    We report a case of isolated pharyngeal plexus injury following posterior plating of a C2 fracture in an 84-year-old white male. Methods include a case report with literature review. The patient presented with dense pharyngeal paralysis and inability to initiate swallowing but maintained true vocal cord movement. The patient required gastrostomy tube feeding for 3 months but eventually recovered his swallowing function. Prior literature on acute pharyngeal paralysis following upper cervical spine fracture repairs is reviewed with recommendations for care of this unique patient population. Traumatic C2 fracture repair can lead to isolated dense pharyngeal paralysis due to pharyngeal plexus injury with subsequent severe dysphagia. Observation may be appropriate in this population, with consideration of tracheotomy for recurrent aspiration. © The Author(s) 2015.

    We assessed the morphological and radiological characteristics of ethmomaxillary sinus (EMS), which is an enlarged posterior ethmoidal air cell occupying the superior portion of the maxillary sinus while draining into superior meatus. This study is based on 1450 patients submitted to CT examination of the paranasal sinuses between 1998 and 2002. Sequential CT scans were obtained in the coronal plane in all the patients with 2.5- to 5-mm section thickness and were evaluated for EMS. The diagnosis of EMS was made when there was a posterior ethmoidal cell occupying the superior part of the maxillary sinus while draining to the superior meatus. When EMS was diagnosed, the morphology of the septum between the and maxillary sinus, and width of the superior meatus, were noted. The EMS was found in 10 of 1450 (0.7%) patients. The coexisting anatomic variations were concha bullosa (50%), upper concha pneumatization (20%), maxillary sinus hypoplasia (20%), uncinate bulla (10%), hypertrophied inferior concha (10%), paradoxic middle concha (10%), and septate maxillary sinus (10%). There was no relation between EMS and sinus disease. The EMS is a rare anatomic variation and does not appear to be associated with sinusitis. The EMS is not a well-studied anatomic variation, and the literature is lacking adequate information about this anatomic variation. This study performed in a large series of patients will possibly contribute to better understanding of this particular anomaly. (orig.)

    Objective: To explore the relation between venous sinus stenosis and pseduotumour cerebri and to discuss the efficacy and strategy of venous sinus stenting for its treatment. Methods: Venous sinus stenting was performed in a total of 9 patients with pseudotumour cerebri accompanied by dural sinus stenosis. The clinical data, including the clinical presentations, intracranial pressure, angiographic findings, pressure of dural sinus,methods of treatment and the therapeutic results, were retrospectively analyzed. Results: Bilateral disc edema was seen in all patients. The pressure gradient in the lateral sinuses was obviously high before stenting (22.67±7.25)mmHg in all patients and a reduction in intra-sinus pressure and pressure gradient was also found (5.78±3.77)mmHg. The symptoms associated with intracranial hypertension were gradually improved or disappeared in two weeks after the placement of the stent in all cases, and the intracranial pressure dropped evidently (12.78±5.97)cm H 2 O. Vision was improved in 7 cases at three months, whereas it remained poor in 2 cases despite normalized intracranial pressure. There was no other permanent procedure-related morbidity. The patients were followed up for 3 months to 5 years, and no recurrence developed. Conclusion: Lateral sinus stenting is an effective method for the treatment of pseudotumour cerebri with dural sinus stenosis. (authors)

  7. Pharyngolaryngeal paralysis in a patient with pharyngeal tuberculosis.

    2015-02-01

    Pharyngeal tuberculosis is a rare disease, and its commonly reported symptoms include sore throat, dysphagia, and throat discomfort. The dysphagia in pharyngeal tuberculosis cases is not due to pharyngolaryngeal paralysis but due to odynophagia. Herein, we describe the first case of dysphagia caused by pharyngolaryngeal paralysis secondary to pharyngeal tuberculosis. An irregular mass at the right nasopharynx was detected in a 57-year-old female patient, along with dysphagia and hoarseness. She had poor right soft palate elevation, inadequate right velopharyngeal closure, poor constrictor pharyngus muscle contraction, and an immobilized right vocal cord, which collectively indicate right pharyngolaryngeal paralysis. Pathological examination and culture testing revealed pharyngeal tuberculosis. She was diagnosed with pharyngolaryngeal paralysis secondary to pharyngeal tuberculosis. The pharyngolaryngeal paralysis resolved after beginning anti-tuberculous treatment. Right pharyngolaryngeal paralysis was attributed to glossopharyngeal and vagus nerve impairment in the parapharyngeal space. Prior reports indicate that peripheral nerve paralysis, including recurrent laryngeal nerve paralysis caused by tuberculous lymphadenitis, often recovers after anti-tuberculous treatment. Pharyngeal tuberculosis rarely causes dysphagia and hoarseness attributable to pharyngolaryngeal paralysis. The neuropathy may recover after anti-tuberculous treatment. Pharyngeal tuberculosis is a new potential differential diagnosis in pharyngolaryngeal paralysis. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to analyze the prevalence and antibiotic resistance of Staphylococcus aureus strains from 118 tonsillectomized adults due to recurrent tonsillitis (RT). The study included strains isolated from the tonsillar surface prior to tonsillectomy, recovered from the tonsillar core at the time of surgery, and from the posterior throat 2-4 weeks after the procedure. Susceptibility of isolates to 19 antibiotics was tested in line with the Clinical and Laboratory Standards Institute recommendations. Irrespective of the stage, the most commonly isolated bacteria were gram-positive cocci, and among them S. aureus. The tonsillar core was the most common site of S. aureus isolation (30.5%), followed by the tonsillar surface (10.8%) and the posterior pharynx (5.9%). This difference turned out to be statistically significant (p Staphylococcus aureus seems to be the most common pathogen isolated from patients tonsillectomized due to RT. Staphylococcal isolates associated with RT are present mostly within the tonsillar core and susceptible to most antibiotics. They are typically isolated from patients between 21 and 30 years of age. Tonsillectomy results in less frequent isolation of S. aureus strains. © 2016 APMIS. Published by John Wiley & Sons Ltd.

    Full Text Available INTRODUCTION: There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp in adenotonsillar tissue. OBJECTIVE: A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. METHODS: Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction. RESULTS: Hp IgG was detected in 57 (89% patients' serum. A total of seven tissue samples from 64 patients (10.9% were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. CONCLUSION: This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas.

    The obturating pharyngeal flap used in correcting velopharyngeal insufficiency has been implicated in creating difficulty in nasal breathing for some patients and/or in causing hyponasal speech, obstructive sleep apnea, and snoring. This is a case report of an individually designed removable prosthesis that positions an acrylic tube through each port lateral to the pharyngeal flap, with the goal of preventing the collapse of the ports during sleep and the consequent snoring. The acrylic tubes maintain an opening through both lateral ports preventing the soft tissues of the lateral walls from vibrating against the pharyngeal flap (causing the snoring sound) and allowing nasal breathing. The acrylic tubes effectively eliminated the patient's problem of snoring. This case study demonstrates that snoring associated with a pharyngeal flap can be controlled prosthetically by maintaining an opening through the two lateral ports, preventing the soft tissues of the walls of the lateral ports from vibrating against the flap.

Initial vitals were temperature of 37.6oC, blood pressure 122/82, heart rate 135, respiratory rate 18, and oxygen saturation 100% on room air. Significant findings: Her physical exam was significant for bilateral tonsillar exudates, cervical lymphadenopathy, and a morbilliform rash that included the palms (Figure 1-4. Laboratory testing was significant for white blood cell (WBC count of 16.5 thous/mcl with an elevation in absolute lymphocytes of > 10 thous/mcl. The monospot and EBV (Epstein-Barr virus panel were positive. Discussion: Infectious mononucleosis (IM is a clinical syndrome characterized by a triad of fever, tonsillar pharyngitis, and lymphadenopathy, and is most commonly associated with primary Epstein-Barr virus (EBV infection.1,2 The incidence of IM in the United States is 500 cases/100,000 person-years, with the highest incidence between ages 15 to 24 years.1 EBV transmission occurs predominantly through exposure to infected saliva3, with an incubation period of 30 – 50 days.1 The majority of patients with IM recover without apparent sequelae and most clinical and laboratory findings resolve by 1 month after diagnosis. Cervical adenopathy and fatigue may resolve more slowly ( > 6 months for fatigue.4,5 IM may be associated with several acute complications including splenic rupture (0.5 – 1% and airway obstruction (1%.6 A morbilliform rash occurs in up to 95% of patients with IM who are treated with beta-lactam antibiotics for presumed group A streptococcal infection.1 Diagnosis is typically made in the setting of the clinical syndrome combined with laboratory test to detect antibodies to certain EBV-associated antigens.7 Primary EBV

    Chronic upper airway obstruction most often occurs when both tonsils and adenoid are enlarged but may occur when either is enlarged. Obstructive sleep syndrome in young children has been reported to be associated with an adverse effect on learning and academic performance. The aim of this study was to evaluate the effect of relative size of the tonsil on academic performance in 4th grade school children. In 320 children, physical examination to determine the size of tonsils was performed by t...

    Full Text Available Abstract Background Dysphagia is a major complication of different diseases affecting both the central and peripheral nervous system. Pharyngeal sensory impairment is one of the main features of neurogenic dysphagia. Therefore an objective technique to examine the cortical processing of pharyngeal sensory input would be a helpful diagnostic tool in this context. We developed a simple paradigm to perform pneumatic stimulation to both sides of the pharyngeal wall. Whole-head MEG was employed to study changes in cortical activation during this pharyngeal stimulation in nine healthy subjects. Data were analyzed by means of synthetic aperture magnetometry (SAM and the group analysis of individual SAM data was performed using a permutation test. Results Our results revealed bilateral activation of the caudolateral primary somatosensory cortex following sensory pharyngeal stimulation with a slight lateralization to the side of stimulation. Conclusion The method introduced here is simple and easy to perform and might be applicable in the clinical setting. The results are in keeping with previous findings showing bihemispheric involvement in the complex task of sensory pharyngeal processing. They might also explain changes in deglutition after hemispheric strokes. The ipsilaterally lateralized processing is surprising and needs further investigation.

    Full Text Available Introduction and Objectives: Acute pharyngitis in adults (APA is one of the most frequent reasons for consultation in primary care. The main objective of this review is to update the therapeutic options for the prevention and treatment of APA and to determine which interventions have the greatest impact in reducing morbidity and improving the quality of life of patients, which directly affects the consumption of health resources. Material and Methods: First clinical criteria of the FAA, indications of tonsillectomy and patterns of antibiotic therapy according to clinical guidelines of national and international scientific societies were defined. Subsequently, the literature related to the treatment of the FAA including other therapeutic options not covered in previous clinical guidelines (P. Leucotomos extract, vaccination by the mucosal route, AM3 and beta-glucans, homeopathy and herbal medicine was revised. ClinicalKey bases and PubMed data were used. Results: The comparison of the studies was difficult due to the disparity of criteria for inclusion and diagnostics, sample sizes, time tracking and poor uniformity in the clinical scales measuring variations. Conclusions: Therefore we cannot conclude whether a therapeutic option is more effective than another in the treatment and prevention of adult APA.

    The purpose of this investigation was to compare child behavior before surgery with experience of pain and anxiety in relation to two techniques of tonsil surgery, to relate previous experiences of surgery/tonsillitis with anxiety and pain, and to compare the children's, parent's and nurse's rating of pain. Ninety-two children (5-15 years) with sleep-disordered breathing (SDB) and with or without recurrent tonsillitis were randomized to partial tonsil resection/tonsillotomy (TT) or full tonsillectomy (TE). Parents: Child Behavior Checklist (CBCL). Children: State-Trait-Anxiety Inventory for Children (STAIC) and seven-point Faces Pain Scale (FPS). Parents/staff: seven-point Verbal Pain Rating Scale (VPRS). Pain relievers were opoids, paracetamol and diclophenac. These children with SDB scored significantly higher on CBCL than did normative groups, but no connection was observed between CBCL rating and experience of pain. There was no relation between pre-operative anxiety and pain. The post-operative anxiety level (STAIC) correlated with pain. The TE-group scored higher on STAIC after surgery. Previous experience of surgery or tonsillitis did not influence post-operative pain. The TE-group rated higher experience of pain despite more medication. The nurses scored pain lower than the parents/children and under-medicated. SDB may influence children's behavior, but with no relation to post-operative pain. The surgical method predicts pain better than does the child's behavior rating. The nurses underestimated the pain experienced by the child.

    Myxoma is a slow growing, benign neoplasm, which pathogenesis still remains disputed. The lesion has well-defined borders but a true capsule is absent. Because of that myxoma can be locally invasive causing bone destruction. A change is mainly observed among persons between 20-30 years of age and is very uncommon in the pediatric population. Most myxomas are observed in myocardium, but rarely may also manifest in the head and neck region. In the paper we describe an unusual case of myxoma of maxillary sinus in a female infant. Diagnostic challenges, treatment, outcome, post-operative follow-up are discussed as well as a review of the literature in order to present many features of this rare pathology. © 2016 MEDPRESS.

    A two-part study using medium field strength magnetic resonance imaging (MRI) was designed to describe normal paranasal sinus development and to prove preliminary criteria for clinical sinus disease. In part 1 of the study the paranasal sinuses were retrospectively evaluated in 80 infants and children aged 0-17 years undergoing brain MRI for indications both unrelated and related to sinus disease. MRI criteria were developed for independent grading of paranasal sinus development and 'anatomical' sinus disease, i.e., diseases as seen by the radiologist. The variability was in extent quantified of sinus pneumatization (a measure of sinus development) in infants and young children. Part 2 was a double-blind prospective study in 21 patients to correlate 'anatomical' disease with 'clinical' sinus disease. In this limited preliminary study, clinical sinus disease was only seen in the patients with moderate or severe anatomical disease (sensitivity 100 percent; specificity 100 percent).

    The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.

    Filling defects of dural venous sinuses are considered to be a challenging problem especially in case of symptomatic patients. Many lesions have to be ruled out such as sinus thrombosis, arachnoid granulations and tumours. Encephalocele into dural sinus is also a rare cause of these filling defects of dural sinuses. Here, we report an extremely rare case with spontaneous occult invagination of temporal brain tissue into the left sigmoid sinus and accompanying cerebellar ectopia. PMID:24311424

    A group of 86 patients with osteomas on the bones of the skull and face, 21 suffered from osteomas of the paranasal sinuses. The mean age of the patients was 50 years, with a predominance of male subjects (2/1). The frontal sinus was the frequently involved (57%), followed by the maxillary, ethmoid and the sphenoid sinuses. Diagnosis was made accidentally in 45% of the cases. The most frequent presenting symptom was headache (57%). Simple excision of the osteoma paranasal sinus was possible in 18 cases. We realize a study of the facts, as well as a review of the literature to know the incidence, diagnosis, indications and surgery technics used in these type of osteomas.

    Acute paranasal sinus infection in children is often diagnosed clinically without the need for radiographic confirmation. Most cases have a favorable outcome following appropriate antibiotic therapy. A small percentage of cases where symptoms and signs are persistent or severe will require emergent imaging to rule out complications related to local spread of disease intraorbitally or intracranially. A strong index of suspicion is required in such cases, and cross-sectional imaging evaluation with CT and MRI should include axial and coronal images of the paranasal sinuses and, where appropriate, the orbits and brain (with attention to the cavernous sinus). There is no role for plain radiography in the evaluation of the complications of acute sinusitis in the pediatric patient. (orig.)

    2013-05-01

    An adult walleye (Sander vitreus) was submitted to Cornell University for evaluation of a hard pale-tan pharyngeal mass attached to the gill arches. Dozens of hard white conical structures radiated from the surface. Microscopically, conical structures were identified as denticles and rested on plates of dysplastic orthodentine, cementum, and acellular bone. A diagnosis of compound odontoma was made based upon the presence of proliferative epithelial and mesenchymal odontogenic tissues that recapitulated tooth structures normally present on gill rakers. Odontomas are classified as hamartomas and typically develop in immature diphyodont mammals. The pharyngeal location and lifelong regeneration of teeth in fish, however, both qualify the present diagnosis in the pharyngeal region of an adult teleost. Ontogenic and morphologic differences between mammalian and piscine dentition and differentials for tooth-bearing tumors in fish are presented within the context of a developmental anomaly.

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Twenty gnotobiotic piglets were inoculated with 5 x 10(8) colony forming units of an Actinobacillus pleuropneumoniae biotype 1-serotype 9 strain onto their tonsils. Five other piglets (controls) were inoculated with phosphate-buffered saline solution. Pigs were euthanized at 30 min, 90 min, 180 min, 6 h, 9 h, 12 h or 24 h after inoculation. At necropsy, samples were taken from the tonsils for bacteriological, histological, immuno-histochemical and electron microscopical examination. A. pleuropneumoniae was isolated from tonsils of all the infected pigs, but not from tonsils of the control pigs. Early after inoculation bacteria were mainly associated with the stratified squamous epithelium and detached epithelial cells. Vacuolization and desquamation of the epithelium was observed and many transmigrating neutrophils were present. At later times after inoculation, bacteria were found closely associated with the crypt-walls and with detached cells present in the crypts. A strong neutrophil migration was observed mainly in the deeper parts of the crypts. It is concluded that attachment of A. pleuropneumoniae to tonsillar epithelial cells probably constitutes a first step in establishing bacteria at this body site.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T 1 , 16T 2 , 32T 3 and 22 T 4 . Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T 1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs

    Chronic upper airway obstruction most often occurs when both tonsils and adenoid are enlarged but may occur when either is enlarged. Obstructive sleep syndrome in young children has been reported to be associated with an adverse effect on learning and academic performance. The aim of this study was to evaluate the effect of relative size of the tonsil on academic performance in 4th grade school children. In 320 children, physical examination to determine the size of tonsils was performed by the otorhinolaryngologist. A questionnaire was developed to assess sleep patterns and problems, and socio-demographic data for the student participants. Furthermore, their school performance was assessed using their grade in mathematics, science, reading, spelling, and handwriting. No association between tonsil size and academic performance was found. Snoring frequency, body mass index and body weight showed a positive relation with tonsil size. There was no association between tonsil size and sleepiness during the day, sleeping habits, hyperactivity, enuresis, history of tonsillectomy in children and parental cigarette smoking and education. In conclusion, this study did not show any significant relationship between tonsil size and academic performance in 4th grade students. Further studies are recommended with a larger sample size, cognitive exams for evaluation of attention, and follow-up of the students until high school, when the discrepancy of the students' academic performance is more obvious.

    Although group A Streptococcus (GAS) pharyngitis is the most common cause of bacterial pharyngitis in children and adolescents, many viral and bacterial infections mimic the symptoms of GAS pharyngitis. Emergency clinicians must recognize the symptomatology of GAS pharyngitis and use appropriate means of diagnosis and treatment to promote good antibiotic stewardship. This issue reviews the signs and symptoms of GAS pharyngitis, as well as associated complications, and provides recommendations for appropriate treatment that focuses on reducing the severity and duration of symptoms, reducing the incidence of nonsuppurative complications, and reducing transmission.

    1976-01-01

    A study was performed to investigate the size of pharyngeal cavity and sexual differences between Korean adult mal e and female by introducing linear analysis of the lateral cephalogram. The radiograms were composed of 46 adult male aged 24.64 and 52 adult female aged 22.74 respectively. In order to study and measure the pharyngeal area, the following skeletal landmarks were selected: S,N,A,Ptm, B,H,H', M ,S-N, FH and CV, and the angle CV-FH was measured to provide a factor for correction of error resulting from improper he ad positioning of subjects, especially in the relative positions of A and H, while radiography. All points to be measured were projected at right angles to the Frankfort plane. For the purpose of measuring the anteroposterior dimensions of pharyngeal cavity the distances were measured in A-Ptm, A-S, S-Ptm and CV-H, and vertical measurements were made in SN-A, SN-PNS, SN-H' and M-H. The obtained results were as follows: 1. The pharyngeal cavity is broader in the vertical than in the anteroposterior diameter in both sex and the maximum sexual differences were showed in the distances between SN and H', and minimal sexual differences in the distances between S and Ptm. 2. In general, the measurements of male were larger than those of female in the anteroposterior dimensions of pharyngea l cavity, but the distances between A and S, between CV and H showed significant sexual differences when evaluated statistically. 3. All of the measurements were larger in male than in female in vertical dimensions of pharyngeal cavity, and there were statistical significances of sexual differences in all variables.

    To describe the diagnosis and treatment of ectopic pyriform sinus parathyroid adenoma. A 44-year-old woman presented with persistent primary hyperparathyroidism after previous failed cervical exploratory surgery. Diagnosis of ectopic pyriform sinus parathyroid adenoma was suggested by computed tomography and technetium-99m sestamibi scintigraphy (99mTc-MIBI SPECT/CT). A submucosal tumor was identified under laryngoscopy and resected by endoscopic CO2 laser. Histopathology confirmed the diagnosis of parathyroid adenoma. Ectopic pyriform sinus locations are rare in parathyroid adenoma. 99mTc-MIBI SPECT/CT facilitates diagnosis, especially in case of previous failed neck exploration. Endoscopic CO2 laser resection is the treatment of choice. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    An osteoblastoma is a benign bone tumor that most often occurs in the vertebral column and the long bones of the extremities. Paranasal sinus involvement is very rare. We report an osteoblastoma of the ethmoid sinus in a 13-year-old boy who presented with exophthalmos. CT demonstrated an expansile, lesion of the right ethmoid sinus, which caused the orbital contents to be compressed and deviated to the right. A mixture of ground glass opacity and dense bone was present. The less dense portions of the lesion showed intense enhancement on MRI; a signal void was present on all sequences in the densely sclerotic areas. Curettage was performed. Histologically, the lesion was composed of proliferating osteoblasts along with small trabeculae of woven bone and rich vascular fibrous stroma. The literature concerning occurrence of osteoblastoma in this unusual location is reviewed and discussed. (orig.)

    Fibrous dysplasia (FD) of the paranasal sinuses is rare and often presents a diagnostic challenge. It is usually secondary to extension of disease from adjacent bones and is rarely limited to the sinuses. We have described three cases of FD involving the paranasal sinuses, including the first reported case of FD isolated to the sphenoid sinus. A brief update of the clinical aspects, radiographic appearance, diagnosis, and management of craniofacial FD is provided.

    Full Text Available Aim: To observe the light and scanning electron microscopy (SEM of the caprine tubal tonsil. Materials and Methods: The study was conducted on six crossbred male goats of 6 months of age. From the median sections of the head, tissue pieces from the nasopharynx around the auditory tube were collected and fixed for histology and SEM. Results: Tonsillar lymphoid tissue was located in the nasopharynx ventral to the auditory tube opening in the lateral wall of the pharynx. The height of the surface epithelium of the tubal tonsil measured 80.17±1.08 μm and was a pseudostratified ciliated columnar type with basal, supporting, and goblet cells. Above the dome of lymphoid nodules, the epithelium was modified into a follicle associated epithelium (FAE, also called lympho-epithelium or reticular epithelium and was characterized by the absence of goblet cells and cilia, reduced number of cell layers, and a large number of lymphoid cells due to interrupted basement membrane. The height of FAE was smaller than that of the surface epithelium and measured 34.33±0.92 μm. The surface of tubal tonsil showed folds and invaginations, which formed crypts. The lamina propria-submucosa underneath the epithelium was formed by the meshwork of reticular and, thin and loose collagen fibers with dome-like accumulation of lymphoid nodules. In the secondary lymphoid nodules, a corona, parafollicular area, and interfnodular area were observed. The average number of lymphoid nodules counted per field under low power magnification of microscope was 1.17±0.17, and the internodular distance was 34.00±4.37 μm.

    Palatine tonsils are principally B cell organs that are the initial line of defense against many oral pathogens, as well as the site of infection for others. While the size of palatine tonsils changes greatly in the first five years of life, the cellular changes during this period are not well studied. Epstein Barr virus (EBV) is a common orally transmitted virus that infects tonsillar B cells. Naïve B cells are thought to be the target of primary infection with EBV in vivo, suggesting that they are targeted by the virus. EBV enters B cells through CD21, but studies of older children and adults have not shown differences in surface CD21 between naïve B cells and other tonsil B cell populations. In this study, we used an 11-color flow cytometry panel to detail the changes in B cell subpopulations in human tonsils over the first five years of life from 33 healthy US children. We provide reference ranges for tonsil B cell subpopulations over this age range. We show that the frequency of naïve tonsil B cells decreases over the early years of life, and that naïve B cells expressed higher surface levels of CD21 relative to other tonsil B cell populations. We show that young children have a higher frequency of naïve tonsil B cells, and importantly that these cells express increased surface EBV receptor, suggesting that young children have a larger pool of cells that can be infected by the virus. © 2017 International Clinical Cytometry Society. © 2017 International Clinical Cytometry Society.

    The rectal tonsil is a rare polypoid lesion exclusively found in the rectum and is considered a reactive proliferation of the lymphoid tissue. Although this lesion is benign, we recommend that it should be differentiated from carcinoid or polypoid type of mucosa-associated lymphoid tissue lymphomas, based on gross findings. In this case report, we describe a case of rectal lesions with a unique appearance in a 41-year-old man. Colonoscopy revealed two 5-mm-sized nodules located opposite from each other on the left and right sides of the lower rectum. Endoscopic mucosal resection was conducted. Histopathologically, both lesions were mainly located in the submucosa and consisted of prominent lymphoid follicles with germinal centers of various sizes. No immunoreactivity of Bcl-2 was seen in the germinal centers. Immunohistochemical staining for kappa and lambda light chains revealed a polyclonal pattern. Therefore, these lesions were diagnosed as rectal tonsils.

    We report herein on 5 patients with odontogenic maxillary sinusitis caused by a dental restoration (caries cutting, cavity preparation, inlay restoration). Odontogenic maxillary sinusitis was noted following dental restoration. Even though the pulp cavity and dental pulp were intact, the odontogenic maxillary sinusitis occurred caused by an apical lesion. Infection by way of the dentinal tubules was suggested to be a cause of the pathophysiology. Endoscopic sinus surgery was indicated in patients with intractable odontogenic maxillary sinusitis caused by the dental restoration. Cone-beam x-ray CT was useful for the accurate diagnosis of odontogenic maxillary sinusitis caused by a dental restoration. Physicians should thus be aware of the possibility that a tooth, which has undergone dental restoration, may cause odontogenic maxillary sinusitis.

    The cost of treatment as it affects comparative effectiveness is becoming increasingly more important. Because cost data are not readily available, we evaluated the charges associated with definitive nonsurgical therapy for early-stage lateralized tonsil cancers. Patients treated with unilateral radiation therapy (RT) for T1 or T2 tonsil cancer between 1995 and 2007 were retrospectively reviewed. Total and radiation-specific charges, from 3 months before to 4 months after radiation, were adjusted for inflation. All facets of treatment were evaluated for significant associations with total billing. Eighty-four patients were identified. Three-year overall survival, disease-specific survival, and recurrence-free survival were 97 % [95 % confidence interval (CI) 0.88-0.99], 98 % (95 % CI 0.89-1), and 96 % (95 % CI 0.88-0.99), respectively. The median for radiation-specific charges was $60,412 (range $16,811-$84,792). The median for total charges associated with treatment was $109,917 (range $36,680-$231,895). Total billing for treatment was significantly associated with the year of diagnosis (p = 0.008), intensity-modulated radiation therapy versus wedge pair RT (p = 0.005), preradiation direct laryngoscopy (p charges associated with definitive nonsurgical therapy for early-stage lateralized tonsil cancer have a wide range likely due to treatment-related procedures, the use of chemotherapy, and evolving RT technologies. These benchmark data are important given renewed interested in primary surgery for tonsil cancer.

    Full Text Available A comparative assessment of cardiac performance by the data of clinical-instrumental examination of 50 patients aged 5-15 years with persisting form of partially-controlled atopic bronchial asthma in the period between the attacks of the disease was made. Children were divided into two groups depending on presence of concomitant chronic tonsillitis (18 patients or absence of the latter (32 patients. In all cases by the data of spirography in children against chronic tonsillitis in the period between the attacks of the disease there were revealed ventillation disorders in the lungs by obstruction type, this promoted elevation of pressure in the pulmonary artery. Only in this group of patients in 27,8% of cases pulmonary arterial hypertension of moderate severity was revealed. By echocardiography data in children with asthma against chronic tonsillitis reliably more often (р<0,01 there was revealed decrease of contractile function of myocardium of the left cardiac ventricle; this was caused by the presence of metabolic disturbances in the myocardium in the majority of cases (83,3%. These changes were registered on the electrocardiogram in the form of repolarisation changes of the ventricular complex. Presence of concomitant chronic tonsillitis in children with bronchial asthma favored formation of pulmonary hypertension on the one side and worsening of contractile ability of myocardium of the left cardiac ventricle on the other side; this required performing therapeutic-preventive measures for sanation of chronic infectious focus in the nasopharynx to prevent formation of chronic cardiac insufficiency during asthma course.

    The objective of this study was to comparatively evaluate 3 different sinus lift tools, namely umbrella-shaped sinus lift curette YSL-04, our recently designed probe-improved sinus lift curettes, and our newly invented elevator 014, using our previous developed goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time. Goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time were generated according to our previously developed protocol. The effectiveness for each tool was evaluated through the length of sinus mucosa detached in mesial and distal directions or buccal and palatal directions, and the space volume created by detaching maxillary sinus mucosa in mesial, distal, buccal and palatal directions. The results showed that all 3 sinus lift tools could transcrestally detach the maxillary sinus mucosa and create extra space under the elevated sinus floor on the goat ex vivo sinus models. Moreover, our newly invented elevator 014 had advantages over the other 2 in term of the capability to detach the sinus mucosa. Our newly invented elevator 014 might be a promising tool for detaching maxillary sinus mucosa in transcrestal maxillary sinus floor elevation.

    The objective of the study was to evaluate the association between changes in laryngeal sensation and initiation of swallowing reflex or swallowing function before and after (chemo)radiotherapy. A prospective study was conducted in a tertiary referral university hospital. Thirteen patients who received (chemo)radiotherapy for treatment of laryngeal or hypopharyngeal cancer were included. Laryngeal sensation was evaluated at the tip of the epiglottis before and 1, 3 months, and 1 year after (chemo)radiotherapy. Videofluoroscopy was performed at the same time. Quantitative determinations included changes in laryngeal sensation, computed analysis of pharyngeal delay time, the distance and velocity of hyoid bone movement during the phase of hyoid excursion, and pharyngeal residue rate (the proportion of the bolus that was left as residue in the pharynx at the first swallow). Laryngeal sensation significantly deteriorated 1 month after (chemo)radiotherapy, but there was a tendency to return to pretreatment levels 1 year after treatment. Neither pharyngeal delay time nor displacement of the hyoid bone changed significantly before and after (chemo)radiotherapy. In addition, there was no significant difference in the mean velocity of hyoid bone movement and the amount of stasis in the pharynx at the first swallow before and after (chemo)radiotherapy. After (chemo)radiotherapy, laryngeal sensation deteriorated. But, in this study, videofluoroscopy showed that swallowing reflex and function were maintained.

    The purpose of this study was to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). The author examined the extent and the recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus (67.9%), posterior ethmoid sinus (48.9%), frontal sinus (42.0%) and sphenoid sinus (41.4%). The characteristic features of CT images of the sinusitis were sinus opacification (22.4%), mucoperiosteal thickening (34.3%), and polyposis (2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babbel's classification. They were 1) infundibular (13.0%), 2) ostiomeatal unit (67.4%), 3)sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns (18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus, both posterior sinuses were 11.4%, 66.8%, 6.3%, respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%, 79.2%, 45.1% respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess 5.2%. The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns and the proximity of the important structures to the posterior paranasal sinuses.

    2014-10-01

    Full Text Available Chronic tonsillitis are the most common diseases of the upper respiratory tract. One of the causes of tonsillitis, with severe clinical manifestations or erased is the Epstein - Barr virus (EBV. According to the literature, more than 90% of the adult population infected with EBV and are lifelong carriers of the virus. After primary infection replication of the virus in asymptomatic or in the case of a weakened immune system may develop infectious mononucleosis. Primary EBV infection in adolescence and adults is much greater than in children and often causes the formation of chronic forms. The main entrance gate is EBV oropharyngeal epithelium. In epithelial cells undergoing complete EBV replication with lysis of cells and the formation of a large number of virions. EBV infects B lymphocytes through the interaction of the surface gp320 virus with CD21 (receptor for complement component C3d. In EBV-infected B lymphocytes are two possible kinds of replication: lytic and latent process. During replication of EBV lytic expressed approximately 100 proteins are immunogenic but are 4 types of proteins, which have specific antibodies: early antigen - EA; viral capsid antigen - VCA; Epstein-Barr nuclear antigen - EBNA; latent membrane protein - LMP. LMP-1 induced bcl-2 (a blocker of apoptosis in B-cells and promotes proliferation and migration of B-lymphocytes. Thus, EBV infection is characterized by widespread, reactivation of infection from infected parts that most often manifests itself with recurrent infection with symptoms of chronic tonsillitis. Objective: what features of general and local immunological parameters inherent in chronic tonsillitis in the acute stage, caused by reactivation of EBV infection. Materials and methods. The study included 311 patients with chronic tonsillitis subcompensated in the acute stage. Microbiological testing of samples produced from the throat, determined EBV DNA in saliva, EVB-VCA-IgM, EVB-EA-IgG and EVB-NA-IgG in

    Full Text Available Introduction: The sphenoid adenoid cystic carcinoma is a rare malign neoplasm, in the head and neck and when located in the paranasal sinuses, it is formed in the minor salivary glands. It grows slowly and is characterized by a large invasion of the adjacent tissues, and also has a large capacity of metastasis. The surgery associated with post-operative radiotherapy is used as treatment. Objective: To describe a case of sphenoid sinus adenoid cystic carcinoma in a male, black, 62 year patient. Case Report: N.L.B., 62 years of age, male, had bloody rhinorrhea for 6 months associated with bilateral nasal obstruction. The nasofibroscopy showed lesion of polypoid aspect in the left nasal cavity. He was submitted to biopsy and the anatomopathological exam showed adenoid cystic carcinoma and the patient was forwarded to oncology. Conclusions: The importance of conducting the differential diagnosis between chronic nasosinusal infection and nasosinusal tumors.

    Osteoblastoma is a rare benign bone tumor that occurs unusually in the nasal sinuses. We report one case of sinonasal osteoblastoma in a 12-year-old girl who presented with nasal obstruction and telecanthus on the right side. Computed tomography revealed a lesion of the right ethmoid sinus with heterogenous bony density, which was displacing the orbital contents and the skull base. Biopsy caused significant bleeding. Magnetic resonance imaging showed intense homogeneous enhancement with typical flow-void areas due to large pathological vessels. This MRI feature must alert the clinician on the diagnosis before biopsy and surgical resection after embolization is performed. This case report describes the diagnostic and therapeutic difficulties of this rare tumor.

    Respiration involves the complex coordination of several pump and upper airway/pharyngeal muscles. From a respiratory perspective, the major function of the pharyngeal muscles is to keep the airway patent allowing for airflow in and out of the lung with minimal work by the respiratory pump muscles. The activity of each of the pharyngeal muscles varies depending on its function, but many reduce their activity during sleep. In healthy individuals, these muscles can respond to respiratory stimul...

    The purpose of this study was to investigate the incidence and the prognostic value of retro-pharyngeal lymphadenopathy in nasopharyngeal carcinoma patients using contrast enhanced computed tomography (CT). In conclusion, using CT imaging, the presence of retro-pharyngeal lymphadenopathy in patients with nasopharyngeal carcinoma does not appear to affect the prognosis. In patients with clinical NO disease, the identification of retro-pharyngeal lymphadenopathy based only on CT imaging is not sufficient evidence for an N1 classification. (N.C.)

    Assess paranasal sinus distribution of topical solutions following endoscopic sinus surgery (ESS) using various delivery devices. Experimental prospective study. Ten cadaver sinus systems were irrigated with Gastroview before surgery, after ESS, and after medial maxillectomy. Delivery was via pressurized spray (NasaMist), neti pot (NasaFlo), and squeeze bottle (Sinus Rinse). Scans were performed before and after each delivery with a portable CT machine (Xoran xCAT), and blinded assessments were made for distribution to individual sinuses. Total sinus distribution was greater post-ESS (P squeeze bottle > pressurized spray (P spray solutions in un-operated sinuses provide little more than nasal cavity distribution. Use of squeeze bottle/neti pot post-ESS offers a greatly enhanced ability to deliver solutions to the paranasal sinuses.

    Coronal CT of the paranasal sinuses and the ostiomeatal complex (OMC) was performed before and 12 months after bilateral functional endoscopic sinus surgery (FESS) in 30 patients with sinusitis and 12 patients with nasal polyposis. The extent of sinus mucosal thickening was graded, and the patency of the OMC was evaluated. After FESS, the percentage of open OMCs had increased from 42% to 83% in the sinusitis group, and from 8% to 45% in the polyposis group. There was only a small improvement in mucosal score in sinuses with opened OMC, so that the overall extent of sinus opacification before and after FESS was almost the same. Despite this, 91% of the patients reported clinical relief of symptoms. Preoperative coronal CT of the paranasal sinuses serves as an anatomical map for the surgeon, but there is no benefit of routine postoperative CT. (orig.)

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

  15. Odontogenic sinusitis: an ancient but under-appreciated cause of maxillary sinusitis.

    Patel, Nimish A; Ferguson, Berrylin J

    2012-02-01

    For well over 100 years, it has been appreciated that maxillary dental infections can cause sinusitis. This insight has been largely overlooked with the advent of functional endoscopic sinus surgery (ESS) and its emphasis on the osteomeatal complex. We review several recent case series and reviews of odontogenic sinusitis that characterize and discuss emerging diagnostic modalities in odontogenic sinusitis. In recent publications on odontogenic sinusitis, up to 40% of chronic bacterial maxillary sinus infections are attributed to a dental source, which is far higher than the previously reported incidence of 10%. Plain dental films and dental evaluations frequently fail to detect maxillary dental infection that can be causing odontogenic sinusitis. However, sinus computed tomography (CT) or Cone Beam Volumetric CT (CBVCT) are far more successful in identifying dental disease causing sinusitis. The microbial pathogens of odontogenic sinusitis remain unchanged from earlier reviews; however, the clinical findings in odontogenic sinusitis are better described in recent reviews. Successful treatment of odontogenic sinusitis requires management of the odontogenic source and may require concomitant or subsequent sinus surgery. Odontogenic sinusitis is frequently recalcitrant to medical therapy and usually requires treatment of the dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent ESS is required. Evaluation of all patients with persistent chronic rhinosinusitis (CRS) should include inspection of the maxillary teeth on CT scan for evidence of periapical lucencies. Unilateral recalcitrant disease associated with foul smelling drainage is especially characteristic of odontogenic sinusitis. High-resolution CT scans and CBVCT can assist in identifying dental disease.

  16. Bone suture and lateral sinus lift surgery

    2015-01-01

    Full Text Available Bone suture in lateral sinus lift has four indications. Three of them depend on creating a hole in the lateral maxillary sinus wall above the antrostomy window for securing the elevated medial maxillary sinus membrane to manage perforated Schneiderian membrane. Covering the buccal antrostomy window with the buccal fat pad (BFP for better nourishment of the inserted graft and as an alternative for bone tags in fixation of collagen membrane has been reported previously. A new indication for firmly anchoring the BFP to the medial maxillary sinus wall as the last resort for the management of perforated Schneiderian membrane is explained in this article.

    1994-01-01

    To describe MR findings of cerebral venous sinus thrombosis. We reviewed 11 MR images of six patients with cerebral venous sinus thrombosis. The MR images were retrospectively analyzed in terms of location and signal intensity of the thrombi, parenchymal lesions such as hemorrhage and edema, and changes in follow up study obtained in 4 patients. The thrombus in venous sinus was visualized on MRI in all six patients. The most frequently involved sites were superior sagittal sinus(n=4) and left transverse sinus(n=4). Signal intensity of the thrombus was isointense or hyperintense on both T1- and T2-weighted images with loss of normal signal void of the sinus on all sequences in all patients. Parenchymal lesion was patients in five of six cases, manifested as local hemorrhage in three and edema in three cases(one case overlapped). Local edema seen in three patients was completely resolved on follow up study of seven to 29 days intervals. It is concluded that iso- or high signal intensity with loss of signal void in venous sinus is virtually diagnostic of venous sinus thrombosis. If there are local parenchymal lesions such as hemorrhage and/or edema of unknown causes, cerebral venous sinus thrombosis should be included in differential diagnosis

    Streptococcus pyogenes is a human-specific and globally prominent bacterial pathogen that despite causing numerous human infections, this bacterium is normally found in an asymptomatic carrier state. This review provides an overview of both bacterial and human factors that likely play an important role in nasopharyngeal colonization and pharyngitis, as well as the development of acute rheumatic fever and rheumatic heart disease. Here we highlight a recently described role for bacterial superantigens in promoting acute nasopharyngeal infection, and discuss how these immune system activating toxins could be crucial to initiate the autoimmune process in rheumatic heart disease.

    An aberrant sinus anatomy or pathology can influence the sinus lift technique if it is encountered during surgical exposure. The purpose of the present study was to determine the prevalence of sinus disease and variations of normal anatomy among edentulous patients prior to sinus augmentation. 120 patients attending a private surgical practice (53 women and 67 men, with a mean age of 62.02 years, ranging between 34 and 81 years old) for whom treatment was planned for sinus augmentation were evaluated--medical history, radiographic and clinical examinations. Computerized tomograms (CT) and 3D reconstructions from 240 sinuses were analyzed using Dental CT. Abnormalities were diagnosed in 74.2% of cases. Mucosal thickening was the most prevalent abnormality (68.3%), followed by retention cysts (15.8%) and opacification (9.2%). The diagnosed conditions included mucosal thickening, chronic sinusitis, sinus cysts and polyps. The prevalence of one or more septa per sinus was found to be 30%. Males present pathology more often than females (p=.028). No statistical correlation could be found between age and pathology (p>0.05) No significant differences in age or gender between patients with and without sinus septum were found (p>0.05). The results reinforce the importance of thorough history taking and clinical and radiographic assessment prior to performing sinus augmentation, to prevent the probability of complications.

    Full Text Available Observation of the swallowing dynamics is an issue that demands close attention by the health professionals involved in the diagnosis and management of patients with dysphagia. This article is a review of the literature aimed to enhance the knowledge regarding the speech therapy assessment of pharyngeal dysphagia in elder adults. The disorder of the swallowing is called dysphagia and it is defined as difficulty swallowing. The dysphagia is often caused by affectation of mechanical or neuromuscular components of the swallowing mechanism. This type of disorder is likely to impact the the oral, pharyngeal and esophageal phases of the swallowing. The speech therapist should take into account assessing aspects such as level of consciousness, vital signs, whether or not the patient is ventilator dependent, means of feeding, if intubated what type of cannula, whether or not the patient uses a speaking valve (if a trach tube is present, nutritional status, the patient’s expressive and receptive language, the anatomical and physiological state of the oral motor structures. When assessing swallowing clinicians should also make sure to develop an adequate beside clinical, voice assessment and videofluoroscopy.

  12. Hallucigenia's head and the pharyngeal armature of early ecdysozoans.

    The molecularly defined clade Ecdysozoa comprises the panarthropods (Euarthropoda, Onychophora and Tardigrada) and the cycloneuralian worms (Nematoda, Nematomorpha, Priapulida, Loricifera and Kinorhyncha). These disparate phyla are united by their means of moulting, but otherwise share few morphological characters--none of which has a meaningful fossilization potential. As such, the early evolutionary history of the group as a whole is largely uncharted. Here we redescribe the 508-million-year-old stem-group onychophoran Hallucigenia sparsa from the mid-Cambrian Burgess Shale. We document an elongate head with a pair of simple eyes, a terminal buccal chamber containing a radial array of sclerotized elements, and a differentiated foregut that is lined with acicular teeth. The radial elements and pharyngeal teeth resemble the sclerotized circumoral elements and pharyngeal teeth expressed in tardigrades, stem-group euarthropods and cycloneuralian worms. Phylogenetic results indicate that equivalent structures characterized the ancestral panarthropod and, seemingly, the ancestral ecdysozoan, demonstrating the deep homology of panarthropod and cycloneuralian mouthparts, and providing an anatomical synapomorphy for the ecdysozoan supergroup.

    The search for developmental mechanisms driving vertebrate organogenesis has paved the way toward a deeper understanding of birth defects. During embryogenesis, parts of the heart and craniofacial muscles arise from pharyngeal mesoderm (PM) progenitors. Here, we reveal a hierarchical regulatory network of a set of transcription factors expressed in the PM that initiates heart and craniofacial organogenesis. Genetic perturbation of this network in mice resulted in heart and craniofacial muscle defects, revealing robust cross-regulation between its members. We identified Lhx2 as a previously undescribed player during cardiac and pharyngeal muscle development. Lhx2 and Tcf21 genetically interact with Tbx1, the major determinant in the etiology of DiGeorge/velo-cardio-facial/22q11.2 deletion syndrome. Furthermore, knockout of these genes in the mouse recapitulates specific cardiac features of this syndrome. We suggest that PM-derived cardiogenesis and myogenesis are network properties rather than properties specific to individual PM members. These findings shed new light on the developmental underpinnings of congenital defects.

    Objective: To evaluate the efficacy and risk of endovascular treatment for intracranial venous sinus thrombosis. Methods: Twenty seven patients with intracranial venous sinus thrombosis confirmed by CT, MRI, MRV and/or DSA, from 2004 September to 2006 September, were treated with anticoagulant therapy but without response and then followed by multiple modalities including endovascular treatment. Nineteen of them accepted intravenous thrombolysis and mechanical thrombus maceration, another 5 accepted intravenous thrombolysis, mechanical thrombus maceration and intraarterial thrombolysis and the last 3 with stenting. Results: After thrombolysis, symptoms and signs of 23 patients improved obviously and headache disappeared in 18 of them, but with only mild degree in other 5 and no improvement in 3. Twenty one patients among them achieved recanalization of sinuses completely as confirmed on postprocedural angiography, MRI and MRV studies taken prior to hospital discharge and other 3 achieved recanalization of sinuses partly. Conclusion: Endovascular treatment is an effective and safe measure for potentially catastrophic intracranial dural sinus thrombosis. (authors)

    Perioperative straight sinus thrombosis is extremely rare. A 59-year-old female was admitted to our department because of incidentally found small anterior cerebral artery (A1) aneurysm with microbleeding. After clipping the cerebral aneurysm, she had delayed emergence from anesthesia, total aphasia, and right hemiparesis. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the head showed hyperintensity in the bilateral caudate nuclei, putamina, and thalami, and computed tomography of the head showed a hyperdense straight sinus, suggesting straight sinus thrombosis. Her neurologic symptoms improved gradually, and she achieved a full clinical recovery, with radiological evidence of recanalization of the straight sinus at follow-up. The possibility of straight sinus thrombosis should be considered in postoperative patients with unexplained postoperative deficits when MRI demonstrates hyperintensity in the bilateral basal ganglia and thalami on FLAIR signal images.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. © 2016 The authors.

    Haemophilus influenzae (Hi) causes respiratory tract infections and is also considered to be a commensal, particularly in preschool children. Tonsils from patients (n = 617) undergoing tonsillectomy due to chronic infection or hypertrophy were examined. We found that 51% of tonsils were positive for Hi, and in 95% of cases analyzed in detail (n = 39) Hi resided intracellularly in the core tonsillar tissue. Patients harbored several intracellular unique strains and the majority were nontypeable Hi (NTHi). Interestingly, the isolated NTHi bound soluble immunoglobulin (Ig) D at the constant heavy chain domain 1 as revealed by recombinant IgD/IgG chimeras. NTHi also interacted with B lymphocytes via the IgD B-cell receptor, resulting in internalization of bacteria, T-cell-independent activation via Toll-like receptor 9, and differentiation into non-NTHi-specific IgM-producing cells. Taken together, IgD-binding NTHi leads to an unspecific immune response and may support the bacteria to circumvent the host defense.

    The present randomised, double-blind, placebo-controlled study was conducted to determine whether consumption of probiotic Lactobacillus rhamnosus GG (GG) would lead to the recovery of GG in tonsil tissue. After 3 weeks’ daily consumption of GG as a single strain (n 20), GG as a part of a multispecies combination (n 17) or placebo (n 20), tonsil tissue samples were collected from fifty-seven young adults during tonsillectomy due to chronic or recurrent tonsillitis. Strain-specific real-time PCR was used to detect GG in the tonsil tissue. GG was recovered in the tonsil sample of 40% of the subjects in the GG group, 41% in the multispecies group and 30% in the placebo group (P value between groups 0.79). In all subjects with positive recovery of GG in the tonsil tissue, GG was also recovered in the faecal sample taken at the start of the intervention and at the time of the tissue sample collection, which indicates more persistent adherence of the probiotic. To conclude, GG can be recovered from tonsil tissue after oral administration as a singlestrain probiotic or as a part of a multispecies probiotic combination. The present results suggest that individual variation exists in the ability of GG to adhere to tonsil tissue. Persistence of GG appears to be high in tonsil tissue as well, in addition to persistence in faecal samples, which has been demonstrated previously. Further clinical trials are warranted to evaluate whether probiotic adherence in the tonsil tissue could have a role in respiratory symptom prevalence.

    Objective: A description is made of transcrestal sinus lift using the sinus balloon technique, evaluating the bone height achieved and implant success one year after prosthetic loading. Material and method: Between January and July 2007, transcrestal sinus lift using the sinus balloon technique for dental implant placement was carried out in 6 patients. A panoramic X-ray study and maxillary computed tomography scan were carried out before the operation, in order to discard possible sinus pathology. During the intervention, the integrity of the sinus membrane was evaluated using a Medi Pack Pal endoscope (Farol Store and Co., Tuttlingen, Germany), and the intraoperative complications were analyzed. The dental implants were placed in the same surgical step in the presence of 3 mm or more of residual bone. Following the operation, panoramic X-rays were used to assess the bone height gained. One year after prosthetic loading, the implant success rate was determined based on the criteria of Buser. Results: One patient was excluded due to Schneider’s membrane perforation as confirmed by endoscopy. Trans-crestal sinus lift was carried out in 5 males with a mean age of 41.6 years (range 27-51), without antecedents of sinus disease. There were no intraoperative complications. In four patients the implants were placed simultaneous to sinus lift, while in another case implant placement was postponed due to insufficient remaining bone height. The mean gain in height after the operation was 8.7 mm. One year after prosthetic loading, the implant success rate was 100%. Conclusions: Transcrestal sinus lift using the sinus balloon technique is a minimally invasive procedure. In 5 patients the bone height gained proved sufficient to allow implant placement even in the presence of 3 mm of residual bone. Key words: Sinus lift, balloon, sinus complications. PMID:22157670

    Over 80 per cent. of school sickness, whether judged by the number of cases or by the time lost, is transmitted by "droplet" infection.The alleged increase in sickness in public schools is partly apparent, due to increased attention to minor febricula and partly real, due (1) to increased influenza prevalence, the aftermath of the great epidemic of 1918, and (2) to the increased demand for public school education leading to pressure upon accommodation, and especially to overcrowding in dormitories.The bulk of the droplet infections are accounted for by (1) influenza; (2) feverish cold, chill, or P.U.O.; (3) tonsillitis; regular infectious diseases make a comparatively small showing. The incidence and bacteriological findings and the variations in the incidence of pneumonia and otitis media are discussed. Are these complications really secondary epidemics? Tonsillitis, bacteriological findings, milk.Prophylaxis.-Efficacy of vaccines uncertain. Some evidence that they may diminish the onset of complications. If given vaccines should be administered before the danger period, i.e., not later than November.Intensive prophylaxia other than vaccines during the first half of the Lent term would probably amply repay any trouble. It should include:-(a) Special efforts to prevent boys returning to school after the Christmas holidays infected with influenza or febricula.(b) Temperature taking for three weeks.(c) Immediate isolation of all pyrexias and catarrhs.(d) No work before breakfast for at least the first six weeks of the term.(e) All hot baths and showers taken during the day or after games to be followed by cold showers.(f) Prevention of chill in watching games, etc.(g) Increased provision for drying clothes, uniforms and boots.Infection mainly takes place in sleeping quarters, and proper spacing out of beds and thorough "cross" ventilation in dormitories is of paramount importance; instances of cross infection due to proximity of beds; illustrated by bed charts and

    With the introduction of Onyx, transarterial embolization has become the most common endovascular approach to treating dural arteriovenous fistulas (dAVFs), often via the middle meningeal or occipital arteries. The ascending pharyngeal artery (APA) is a less frequently explored transarterial route because of its small caliber, potential anastomoses to the internal carotid and vertebral arteries, and vital supply to lower cranial nerves. To review our institutional experience and highlight the prevalence of APA supply to dAVFs and cases where it is a safe and effective pedicle for embolization. We reviewed our endovascular database (January 1, 1996 to March 1, 2016) for cranial dAVFs, evaluating dAVF characteristics and embolization results for those treated transarterially via the APA. Of 267 endovascularly treated dAVFs, 68 had APA supply (25%). Of these 68 dAVFs, embolization was carried out via this pedicle in 8 (12%) and 7 were ultimately occluded. No complications, including post-treatment cranial neuropathies or radiographic evidence of non-target embolization, were found. For 5 dAVFs, the APA was selected as the initial pedicle for embolization (two marginal sinus, one distal sigmoid, one cavernous, one tentorial). In four of these five cases, dAVF occlusion was achieved via the initial APA feeding artery pedicle. In one case, near-complete, stagnant occlusion was achieved after APA embolization; complete occlusion was achieved after adjunctive embolization of a single additional middle meningeal artery pedicle. In three other cases of complex transverse/sigmoid dAVFs, the APA was used after multiple attempts via middle meningeal and occipital artery pedicles. Occlusion was not achieved transarterially; two of these three dAVFs were ultimately occluded transvenously. In rare, select cases, the APA is an excellent route for transarterial embolization of cranial dAVFs. Published by the BMJ Publishing Group Limited. For permission to use (where not already

    Nonmammalian vertebrates have the capacity of lifelong tooth replacement. In all vertebrates, tooth formation requires contact and interaction between the oral or pharyngeal epithelium and the underlying mesenchyme. To secure lifelong replacement, the presence of odontogenic stem cells has been postulated, particularly in the epithelial compartment. This study uses an advanced teleost fish species, the marine medaka Oryzias melastigma, a close relative to Oryzias latipes, to examine the expression and distribution of telomerase reverse transcriptase (Tert), the catalytic unit of telomerase, in developing pharyngeal teeth and to relate these data to the proliferative activity of the cells. The data are complemented by expression analysis of the pluripotency marker oct4 and bona fide stem cell marker lgr5. Tert distribution and tert expression in developing tooth germs show a dynamic spatiotemporal pattern. Tert is present first in the mesenchyme but is downregulated as the odontoblasts differentiate. In contrast, in the epithelial enamel organ, Tert is absent during early stages of tooth formation and upregulated first in ameloblasts. Later, Tert is expressed and immunolocalized throughout the entire inner enamel epithelium. The pattern of Tert distribution is largely mutually exclusive with that of proliferating cell nuclear antigen (PCNA) immunoreactivity: highly proliferative cells, as revealed by PCNA staining, are negative for Tert; conversely, PCNA-negative cells are Tert-positive. Only the early condensed mesenchyme is both Tert- and PCNA-positive. The absence of tert-positive cells in the epithelial compartment of early tooth germs is underscored by the absence of oct4- and lgr5-positive cells, suggesting ways other than stem cell involvement to secure continuous renewal.

    Dermal sinus tracts are rare congenital lesions located in the midline characterized by a cutaneous pit or dimple. They occur all along the midline neuroaxis, from the nasion and occipital area down to the lumbar and sacral regions, most frequently in the lumbar and lumbosacral region. Here we report a 5-year-old girl who presented with occasional headache. There were two dimples, one on the dorsal aspect of her head and another on her neck. Dermal sinuses are almost always singular and the co-existence of double dermal sinuses has not been reported previously.

It may or may not be associated with Pott′s puffy tumor. In this article, we present 2 cases. A case of frontocutaenous fistula with opening in the upper eyelid at the lateral portion of floor of frontal sinus and another case of chronic frontal sinusitis with sub-periosteal abscess in the forehead on the right side near the eyebrow. Relevant literature has also been reviewed.

  1. A Rational Approach to Sinus Augmentation: The Low Window Sinus Lift

    Directory of Open Access Journals (Sweden)

    Full Text Available Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique that also exploits the guided surgery approach for design and preparation of a lateral window for sinus augmentation, the Low Window Sinus Lift. To illustrate the use of this approach, a case is presented in which the 50-year-old patient had the left maxillary first molar extracted, followed two months later by sinus augmentation and placement of three implants. One year after delivery of the definitive prosthesis, all three implants were successful, and the prosthesis was fully functional. Controlled studies should be undertaken to assess whether this technique provides significant advantages compared to other sinus augmentation approaches.

    Aspiration due to dysphagia is a factor associated with pneumonia during acute stroke. In such cases, it is likely that secretions in the pyriform sinuses enter the laryngeal inlet. The present study was based on the idea that it is possible to reduce aspiration pneumonia by periodically suctioning and removing such secretions (pyriform sinus suctioning), a study was conducted in a single facility. The incidence of pneumonia as a dependent variable was compared between before (control) and after (intervention group) intervention with pyriform sinus suctioning as an independent variable. With a view of unifying the quality and frequency of intervention, two programs to: initially confirm the safety of such suctioning; subsequently enhance/evaluate knowledge and skills related to the procedure (educational); and specify conditions for the implementation and criteria for determining its appropriateness (practical), were developed. The study involved 33 (mean age: 74.6 ± 12.4) and 30 (80.0 ± 8.8) control and intervention group members, respectively, 25 (83.3%) of the latter were treated with pyriform sinus suctioning for 5 days after a stroke. Pneumonia developed in 7 (21.2%) and 2 (6.7%) of the former and latter, respectively. As individuals with a Japan Coma Scale (JCS) score of III or a midline shift on head CT tend to develop pharyngeal dysphagia, the patients were also divided into 2 groups to compare the incidence of pneumonia based on the risk level: low: Japan Coma Scale scores of I-II without a midline shift on head CT; and high: scores of II-III with it. In the latter, the incidence after intervention was markedly lower (p = 0.06, φ = 0.326), while the former did not show changes (p = 0.574, φ = 0.066), supporting the effectiveness of pyriform sinus suctioning to prevent aspiration pneumonia among patients with a low risk level.

    A total of 156 tonsils and 156 mandibular lymph nodes from fattening pigs originating from 13 farms were sampled in Croatian slaughterhouses and examined for Salmonella spp. (n=78 per organ) and Yersinia enterocolitica (n=78 per organ) by cultural methods. Salmonella was isolated from two tonsils only, both originated from animals from the same farm (5.12%), while Y. enterocolitica were recovered from 26 tonsils (33.33%) which could be traced back to 10 farms. Salmonella was absent in mandibular lymph nodes, and Y. enterocolitica was isolated from eight lymph nodes (10.25%) which originated from six farms. Y. enterocolitica was present inside the lymph nodes of two pigs. The high prevalence of Y. enterocolitica in/on pig tonsils could be the result of cross-contamination during splitting the carcasses with head. This procedure may result in higher prevalence of Y. enterocolitica on surface of mandibular lymph nodes than in their depth. Traditional veterinary postmortem examination of pig halves will not necessarily contribute to cross-contamination with Salmonella or Yersinia under conditions of present slaughter practice.

    Objective: Our aim was to determine whether inward or outward movement of the secretions in the paranasal sinuses due to nose blowing after nasal decongestion has any effect on the paranasal sinus computed tomography (CT) images in patients with sinusitis and to asses whether nose blowing may result in misdiagnosis or overdiagnosis in radiological evaluation of sinusitis. Materials and methods: Twenty-four patients with chronic sinusitis were evaluated in an academic tertiary care hospital and data were collected prospectively. After coronal sinus computed tomography scans were performed at 100 mA setting which was half the value of the standard radiation dose suggested by the manufacturer, topical decongestion was applied to each nostril followed by nose blowing 10 min later. Sinus CT scans were then repeated at the same setting. We evaluated the mucosal thickness of medial, lateral, superior and inferior maxillary and frontal sinus walls and the maximal thickness in anterior ethmoidal cells. The measurements prior to and following nose blowing were compared with Wilcoxon signed ranks test. The obtained images were also staged using Lund-McKay staging system separately and the scores were compared with Student's t-test. Results: We observed a tendency towards reduction in mucosal thickness after nose blowing. There were statistically significant differences between maxillary sinus inferior wall and frontal sinus inferior wall mucosal thickness values prior to and after nose blowing. The difference however was very small, about 0.5 mm in magnitude and Lund-McKay score did not change in any of the patients after nose blowing. Conclusion: Nose blowing and topical nasal decongestion does not have any effect on the diagnostic accuracy of sinus CT in chronic sinusitis patients.

    This study determined emm subtypes of Streptococcus pyogenes strains isolated from asymptomatic carriers and children with pharyngitis. All strains were previously investigated for fibronectin-binding genes (prtF1 and prtF2) and antimicrobial susceptibility. The most significant differences between the two groups, which share only 5 of the 14 detected emmsubtypes, concern the presence of the two more common emmsubtypes, 12.0 (50.0% vs. 3.1%, for asymptomatic carriers and children with pharyngitis, respectively) and 1.0 (28.1% vs. 0%, for children with pharyngitis and asymptomatic carriers, respectively).

    Limited evidence exists as to the benefit of tonsillectomy in adult patients. We sought to determine the short-term efficacy of tonsillectomy for recurrent pharyngitis in adults. We conducted a randomized, controlled, parallel-group trial at a tertiary care ear, throat and nose centre in Oulu, Finland, between October 2007 and December 2010. Adult patients with recurrent pharyngitis were randomly assigned to the control group (watchful waiting) or the tonsillectomy group. Our primary outcome was the difference in the proportion of patients with severe pharyngitis (severe symptoms and C-reactive protein level > 40 mg/L) within 5 months. Our secondary outcomes included differences between groups in proportions of patients who had episodes of pharyngitis with or without medical consultation, rates of pharyngitis and numbers of days with symptoms. Of 260 patients referred for tonsillectomy because of recurrent pharyngitis, we recruited 86 participants for our study. Of these, 40 patients were randomly allocated to the control group, and 46 were randomly allocated to the tonsillectomy group. One patient in the control group and no patients in the tonsillectomy group had a severe episode of pharyngitis (difference 3%, 95% confidence interval [CI] -2% to 7%). Seventeen patients in the control group (43%) and 2 patients in the tonsillectomy group (4%) consulted a physician for pharyngitis (difference 38%, 95% CI 22% to 55%). Overall, 32 patients in the control group (80%) and 18 patients in the tonsillectomy group (39%) had an episode of pharyngitis during the 5-month follow-up (difference 41%, 95% CI 22% to 60%). The rate of pharyngitis and number of symptomatic days were significantly lower in the tonsillectomy group than in the control group. There was no significant difference in the number of episodes of severe pharyngitis between the control and treatment groups, and episodes were rare. However, tonsillectomy resulted in fewer symptoms of pharyngitis, consequently

    To properly understand the basic theory and the clinical application of the functional endoscopic sinus surgery and the traditional technique. The indications, extend of excision, operative approach, complication and curative effect of 1,740 cases(3,140 sides) done in the China-Japan Friendship Hospital and Jining Jiaotong Hospital were analysed. Among them, 522 cases(1,032 sides, 30%) received the traditional technique for sinusitis; 1,218 cases(2,108 sides, 70%) received functional endoscopic sinus surgery. Three hundred and ninety-eight cases of traditional ethmoid sinus operation and 352 of functional sinus surgeries were followed-up and their cure rates were 80% and 93% respectively. Both groups had no serious complications. The main indications of functional sinus surgery are infectious nasal sinus diseases or meatus nasi lesion that may interfere with the drainage. Such kinds of diseases have high morbidity than the diffused polyposis and deserves attention. Traditional operations for frontal and maxillary sinusitis should be controlled appropriately, but the traditional sphenoid sinus operation is still an effective treatment for the diffused polyposis.

    This study was performed to compare paranasal sinus tomosynthesis with computed tomography (CT) imaging as a radiologic tool to evaluate the paranasal sinuses, using measurement of the soft tissue thickness of the maxillary sinus. A total of 114 patients with sinusitis who underwent both paranasal sinus digital tomosynthesis (DT) and CT were enrolled in this retrospective study. Two observers independently assessed soft tissue thickness in both maxillary sinus chambers using both DT and CT images. The mean difference in soft tissue thickness measured by each observer was −0.31 mm on CT and 0.15 mm on DT. The mean differences in soft tissue thickness measured with DT and CT were −0.15 by observer 1 and −0.31 by observer 2. Evaluation of the agreement in measurement of soft tissue thickness in the maxillary sinus using DT and CT showed a high intraclass correlation, with the 95% limit of agreement ranging from −3.36 mm to 3.06 mm [intraclass correlation coefficient (ICC), 0.994: p<0.01] for observer 1 and from −5.56 mm to 4.95 mm (ICC, 0.984: p<0.01) for observer 2. As an imaging tool, DT is comparable to CT for assessing the soft tissue thickness of maxillary sinuses in patients with sinusitis.

    Yersiniosis is a common bacterial zoonosis in Europe and healthy pigs are known to be the primary reservoir of human pathogenic Yersinia enterocolitica and Y. pseudotuberculosis. However, little information is available about the prevalence of these pathogens within pig batches at time of slaughter. The tonsils of 7047 fattening pigs, belonging to 100 farms, were aseptically collected immediately after evisceration in two Belgian slaughterhouses. The batch size varied between 70 and 930 pigs. On average, 70 pigs were sampled per batch. The tonsils were examined by direct plating on cefsulodin-irgasan-novobiocin (CIN) agar plates and the number of suspect Yersinia colonies was counted. Pathogenic Y. enterocolitica serotype O:3 were found in tonsils of 2009 pigs (28.5%), originating from 85 farms. The within-batch prevalence in positive farms ranged from 5.1 to 64.4%. The number of Y. enterocolitica in positive pigs varied between 2.01 and 5.98 log10 CFU g(-1) tonsil, with an average of 4.00 log10 CFU g(-1) tonsil. Y. pseudotuberculosis was found in seven farms, for which the within-batch prevalence varied from 2 to 10%. In five of these farms, both Y. enterocolitica and Y. pseudotuberculosis were simultaneously present. Human pathogenic Yersinia spp. are widespread in slaughter pig batches in Belgium as 87% of the tested batches were infected with these pathogens at the time of slaughter. The large variation of the prevalence between batches may lead to different levels of contamination of carcasses and risks for public health. Copyright © 2014 Elsevier B.V. All rights reserved.

    Keratin-specific immune responses in tonsils may be associated with the pathogenesis of pustulosis palmaris et plantaris (PPP). Evaluation of keratin-specific immune responses in tonsils might be useful to predict the effectiveness of tonsillectomy for patients with PPP. The aim of the present study was to clarify the role of keratin-specific immune responses in the pathogenesis of PPP in tonsils. It has been reported that anti-keratin antibodies in serum were higher in patients with PPP and decreased after tonsillectomy, indicating that anti-keratin antibodies might be generated in tonsils. In order to demonstrate the presence of keratin-specific immune responses in tonsils, the numbers of keratin-specific antibody-forming cells (AFCs) in tonsillar and peripheral blood lymphocytes were examined by enzyme-linked immunospot assay. The prognosis of PPP was compared after tonsillectomy. The numbers of keratin-specific IgM and IgG AFCs in tonsils and of IgG AFCs in peripheral blood were significantly increased in patients with PPP. The numbers of keratin-specific IgG AFCs in peripheral blood correlated positively with tonsil and serum IgG antibodies specific to keratin. Our data show that a good prognosis in patients with PPP depended on the numbers of keratin-specific IgG and IgM AFCs in peripheral blood and the levels of keratin-specific IgG antibodies in serum being significantly decreased 6 months after tonsillectomy.

  17. Intracellular persisting Staphylococcus aureus is the major pathogen in recurrent tonsillitis.

    Directory of Open Access Journals (Sweden)

    Andreas E Zautner

    Full Text Available BACKGROUND: The two major indications for tonsillectomy are recurrent tonsillitis (RT and peritonsillar abscess (PTA. Unlike PTAs, which are primarily treated surgically, RT is often cured by tonsillectomy only after a series of failed drug therapy attempts. Although the bacteriological background of RT has been studied, the reason for the lack of success of conservative therapeutic approaches is not well understood. METHODS: In a prospective study, tonsil specimens from 130 RT patients and 124 PTA patients were examined for the presence of extra- and intracellular bacteria using antibiotic protection assays. Staphylococcus aureus isolates from RT patients were characterized by pulsed-field gel electrophoresis (PFGE, spa-typing and MSCRAMM-gene-PCR. Their ability for biofilm formation was tested and their cell invasiveness was confirmed by a flow cytometric invasion assay (FACS, fluorescent in situ hybridization (FISH and immunohistochemistry. FINDINGS: S. aureus was the predominant species (57.7% in RT patients, whereas Streptococcus pyogenes was most prevalent (20.2% in PTA patients. Three different assays (FACS, FISH, antibiotic protection assay showed that nearly all RT-associated S. aureus strains were located inside tonsillar cells. Correspondingly, the results of the MSCRAMM-gene-PCRs confirmed that 87% of these S. aureus isolates were invasive strains and not mere colonizers. Based upon PFGE analyses of genomic DNA and on spa-gene typing the vast majority of the S. aureus isolates belonged to different clonal lineages. CONCLUSIONS: Our results demonstrate that intracellular residing S. aureus is the most common cause of RT and indicate that S. aureus uses this location to survive the effects of antibiotics and the host immune response.

    Fibrous dysplasia is an uncommon benign bone disorder of unknown etiology in which normal medullary bone is replaced by fibrotic and osseous tissue. Solitary involvement of the sphenoid sinus is unusual. Here, we present the case of a 28-year-old man complaining of occipital and vertical headache. Imaging modalities demonstrated an expansile lesion filling the entire sphenoid sinus. Biopsy specimen was obtained by endoscopic sphenoidotomy. Diagnosis of fibrous dysplasia was made by imaging results and pathologic examination.

    Sinusitis of odontogenic origin, which is frequently encountered in routine otolaryngological and dental clinical practice, has been described as a reactive maxillary inflammation secondary to maxillary tooth infection or trauma to an odontogenic disease of maxillary bone, dental extractions, implant placement, or endodontic treatment impairing the integrity of the Schneiderian membrane. The aim of the present review was to investigate and discuss the most recent pathophysiological findings, predisposing odontogenic factors, microbiology, and the possible involvement of bacterial biofilms (BB) in the development of sinusitis. The narrative literature review showed that there might be a correlation between the bacteria present in pathological teeth in communication with the sinus and those found in infected sinus. The formation of a BB might be also involved in the etiopathogenesis of sinusitis of odontogenic origin. In conclusion, the true origin of odontogenic sinusitis is still unresolved. In clinical terms, the choice of suitable therapy depends on the characteristics of the biofilm. Further microbiological studies are required to better investigate the role of BB. © 2015 Wiley Publishing Asia Pty Ltd.

    The volume of the maxillary sinus was estimated by coronal CT scan. The purpose of this study was to compare the estimated volume of the normal maxillary sinus with that of the inflamed maxillary sinus. Patients were classified following evaluation by CT scan of the paranasal sinuses into 3 categories. Group A (n=12): Patients suffered from headache, facial pain and epistaxis, but CT scans of their nasal cavity and paranasal sinus were within normal limits without inflammatory change. Group B (n=69): Patients with bilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory changes in both maxillary sinuses. All of the patients in this group underwent sinus surgery after coronal CT scans. Group C (n=14): Patients with unilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory change in unilateral maxillary sinuses. CT scans of these patients were measured by Plannimeter to take the area of each image of the maxillary sinus. Consecutively imaged areas were summated by integral calculus to obtain an estimate of the sinus volume. The mean maxillary sinus volume in the affected sinuses was significantly smaller than those in the contralateral normal sinuses (p<0.05, Wilcoxon-test). The various volumes of the maxillary sinuses and the developmental cause were discussed. Comparison of groups A with B suggested three distinct patterns; the maxillary sinus volume has decreased due to inflammatory changes in the bone. The small sinuses have a tendency to develop chronic inflammatory change. The aeration in the maxillary sinus may be decreased when anatomic variations that may obstruct the ethmoid infundibulum exist. (K.H.)

    1980-01-01

    Pharyngeal formation was examined in cases where normal or X-irradiated head pieces were transplanted into the postpharyngeal region of normal or irradiated worms. Transplantation experiments were carried out in four different combinations of hosts and grafts: (1) normal host and graft (control), (2) normal host and irradiated graft, (3) irradiated host and normal graft, (4) irradiated host and graft. In the first experiment, well developed pharynges were formed in the areas both anterior and posterior to the graft on the 14th day after transplantation. In the second experiment, formation of new pharynges was delayed compared with that in the first group. In the third experiment, only one pharynx developed in the area posterior to each graft in most cases. In the last experiment, no new pharynx appeared at all. From these results, the influence of X-rays on factors participating in pharyngeal induction was discussed. (author)

  5. Four-bar linkage modelling in teleost pharyngeal jaws: computer simulations of bite kinetics

    2006-01-01

    The pharyngeal arches of the red drum (Sciaenops ocellatus) possess large toothplates and a complex musculoskeletal design for biting and crushing hard prey. The morphology of the pharyngeal apparatus is described from dissections of six specimens, with a focus on the geometric conformation of contractile and rotational elements. Four major muscles operate the rotational 4th epibranchial (EB4) and 3rd pharyngobranchial (PB3) elements to create pharyngeal bite force, including the levator posterior (LP), levator externus 3/4 (LE), obliquus posterior (OP) and 3rd obliquus dorsalis (OD). A biomechanical model of upper pharyngeal jaw biting is developed using lever mechanics and four-bar linkage theory from mechanical engineering. A pharyngeal four-bar linkage is proposed that involves the posterior skull as the fixed link, the LP muscle as input link, the epibranchial bone as coupler link and the toothed pharyngobranchial as output link. We used a computer model to simulate contraction of the four major muscles, with the LP as the dominant muscle, the length of which determined the position of the linkage. When modelling lever mechanics, we found that the effective mechanical advantages of the pharyngeal elements were low, resulting in little resultant bite force. By contrast, the force advantage of the four-bar linkage was relatively high, transmitting approximately 50% of the total muscle force to the bite between the toothplates. Pharyngeal linkage modelling enables quantitative functional morphometry of a key component of the fish feeding system, and the model is now available for ontogenetic and comparative analyses of fishes with pharyngeal linkage mechanisms.

    Studies on the interaction of magnetic fields and biological organisms have centred on the influence of applied magnetic fields on the physiology and behaviour of organisms, including humans, and a search for magnetic sources within the organisms themselves. Evidence continues to accumulate that a wide range of organisms, from bacteria to vertebrates, can detect and orient to ambient magnetic fields (for examples see refs 2-4). Since the discovery that magnetic orientation by bacteria was due to the presence within the organism of magnetic particles of the ferric/ferrous oxide, magnetite, the search has begun for other biogenic deposits of inorganic magnetic material and ways in which the possession of such material might confer on the organism the ability to orient to ambient magnetic fields. Such magnetic material, often identified as magnetite, has been discovered in bees, homing pigeons, dolphins and various other organisms, including man. A variety of hypotheses for the use of magnetite in magnetic field detection have been proposed. We report here that bones from the region of the sphenoid/ethmoid sinus complex of humans are magnetic and contain deposits of ferric iron. The possible derivations and functions of these deposits are discussed.

    Proptosis due to intraorbital process is frequent and secondary to various aetiologies. Its findings in ENT practice is the sign of a serious complication. The purpose of this study is to review a series of patients who presented an exophtalmy. We conducted a retrospective analysis of 15 patients with exophthalmos complicating a rhinosinusal benign disease, diagnosed and treated in our department between January 2003 and December 2010. As their management is different, we excluded all cases of orbital cellulitis. Average age of presentation was 38 years, without sex predominance. Exophthalmos was unilateral, non axial and irreductible in all cases. The average duration of symptoms installation was 18 months. The most common aetiology was fronto-ethmoidal osteomas (9 cases), followed by fronto-ethmoidal mucoceles (5 cases) and spheno-orbito-frontal fibrous dysplasia (1 case). The functional prognosis of the affected eye depended on the aetiology and the degree of ocular injury. In our experience, sinusal causes of exophthalmos comprise osteomas and ethmoidal mucoceles. Medical history, clinical and radiological data as provide the diagnostic. In case of benign tumours, surgery is the curative treatment.

    This study sought to investigate the proportion of patients with suspected sinusitis referred for radiological examination who have radiologically verified sinusitis of odontogenic origin and to describe this type of sinusitis. This investigation is a retrospective study. A total of 303 sinus examinations involving cone beam computed tomography (CBCT) performed at Sunderby Hospital, Luleå, Sweden in 2012 were independently reviewed by two radiologists. The number of cases of maxillary sinusitis and the correlation between maxillary sinusitis and odontogenic infections were determined. Overall, 24% of the verified cases of sinusitis were odontogenic. An odontogenic origin was identified in 40% of unilateral maxillary sinusitis cases but only 6% of bilateral maxillary sinusitis cases ( p  = 0.0015). Forty-nine out of 54 patients with periapical destruction had adjacent mucosal swelling in the maxillary sinus, but only 15 of these patients satisfied the criteria for sinusitis. The present study confirms the close relationship between odontogenic infections and unilateral maxillary sinusitis. Level of Evidence 4.

    Recent work indicates that upper airway dilator muscles of individuals with obstructive sleep apnea syndrome (OSAS) demonstrate an increased level of activity during wakefulness compared with normal subjects. In addition, massive bursts of pharyngeal dilator activity are associated with the termination of upper airway occlusive events during sleep. This complex pattern of altered pharyngeal dilator activation is also observed in the English bulldog, an animal model of OSAS. In the present study, it was hypothesized that such alterations in activity level might lead to changes in the structure of pharyngeal muscles in the bulldog. Full-thickness biopsies were obtained from two pharyngeal dilator muscles, the sternohyoid (SH) and geniohyoid, as well as a limb muscle, the anterior tibialis, in bulldogs (n = 5) and control dogs (n = 7). Immunohistochemical analysis of myosin heavy chain expression revealed an increased contribution of fast type II myosin heavy-chain fibers to SH in bulldogs. The bulldog SH also demonstrated increased connective tissue content compared with control dogs, consistent with the presence of fibrosis. Both pharyngeal dilators in the bulldog exhibited an elevated proportion of morphologically abnormal fibers indicative of ongoing or prior injury. No differences in any of the above parameters were seen between bulldogs and control dogs in the anterior tibialis limb muscle. We conclude that the chronic load and altered pattern of usage imposed on the upper airway dilators in OSAS lead to myopathic changes that may ultimately impair the ability of these muscles to maintain pharyngeal patency.

    Clinical prediction rules do not incorporate real-time incidence data to adjust estimates of disease risk in symptomatic patients. To measure the value of integrating local incidence data into a clinical decision rule for diagnosing group A streptococcal (GAS) pharyngitis in patients aged 15 years or older. Retrospective analysis of clinical and biosurveillance predictors of GAS pharyngitis. Large U.S.-based retail health chain. 82 062 patient visits for pharyngitis. Accuracy of the Centor score was compared with that of a biosurveillance-responsive score, which was essentially an adjusted Centor score based on real-time GAS pharyngitis information from the 14 days before a patient's visit: the recent local proportion positive (RLPP). Increased RLPP correlated with the likelihood of GAS pharyngitis (r(2) = 0.79; P biosurveillance data into clinical guidelines for GAS pharyngitis and other communicable diseases should be considered for reducing missed cases when the contemporaneous incidence is elevated and for sparing unnecessary antibiotics when the contemporaneous incidence is low. Delivering epidemiologic data to the point of care will enable the use of real-time pretest probabilities in medical decision making.

    To assess the presentation of allergic fungal sinusitis and describe the line of management in our setup. Culture and sensitivity / fungal stain proven 20 cases of allergic fungal sinusitis were selected for the study, irrespective of age and gender. Data including age, gender, socioeconomic status, signs, symptoms, laboratory findings (especially Immunoglobulin E and eosinophil count) and imaging studies (Computed Tomography and /or Magnetic Resonance Imaging) were noted for the study. Pre and postoperative medical treatment, surgery performed, follow-up; residual/recurrence disease and revised surgery performed were also recorded. In this series, allergic fungal sinusitis was a disease of younger age group with an average age of 20.75 years with male dominance (70%). Poor socioeconomic status (80%), allergic rhinitis (100%) and nasal polyposis (100%) were important associated factors. Nasal obstruction (100%), nasal discharge (90%), postnasal drip (90%) and unilateral nasal and paranasal sinuses involvement (60%) were the commonest presenting features. Aspergillus (60%) was the most common etiological agent. In all cases (100%), increased eosinophil count and IgE levels were present. Orbital (20%) and intracranial (10%) involvement were also seen. Surgical management was preferred in all cases. Functional endoscopic sinus surgery in 90% cases and lateral rhinotomy in 10% cases were performed. Recurrence / residual disease was seen in 20% cases. In this series, allergic fungal sinusitis was seen in immunocompetent, young males, belonging to poor socioeconomic status, suffering from allergic rhinitis and nasal polyposis, presenting with nasal obstruction, nasal discharge and postnasal drip. Functional endoscopic sinus surgery was the most important problem solving procedure while lateral rhinotomy was reserved for extensive disease. (author)

    Variations of the dural venous sinuses may result in inaccurate imaging interpretation or complications during surgical approaches. One variation of the dural venous sinuses reported infrequently in the literature is the occipital sinus. We report an exceptional case of occipital sinus thrombosis. A 48-year-old right-handed man with a 5-month history of hypertension and chronic renal failure presented with cephalalgia, vomiting, and blurred vision evolving over 48 hours. Neurological examination revealed papillary edema stage 1 with no others abnormalities. An initial brain computed tomography (CT) scan performed was normal. The opening pressure of cerebrospinal fluid (CSF) was 35 cmH2O with normal level of protein and no hypercellularity in CSF analysis. The evolution was marked by the occurrence of generalized tonic-clonic seizure. A second CT scan performed showed a hyperdensity of the occipital sinus. Magnetic resonance imaging and magnetic resonance venography studies confirmed the diagnosis with highlighting the thrombosis of the occipital sinus in association to an ectasia of the torcular. The patient received adequate anticoagulation for 6 months in association to antiepileptic drugs with a good evolution. According to our review, such a thrombosis must be a rare condition, because our literature search has shown a lack of any report describing this condition. Herein, we review the anatomy of the occipital sinus and we illustrate the characteristics of this unusual thrombosis with multiple imaging modalities. Understanding of the cerebral venous anatomy and recognition of venous variations essentially help when dealing with a pathology, which presents along with a particular venous variation, no matter how rare this combination is.

Diabetes mellitus type 1 (also known as type 1 diabetes, or T1DM is one of the important factors that could significantly complicate the therapy of chronic tonsillitis. T1DM is a form of diabetes mellitus that results from the autoimmune destruction of the insulin-producing beta cells in the pancreas. The aim of our study was to explore the dynamics of immunologic indicators during the active disease and treatments in patients with various forms of chronic tonsillitis, including tonsillitis complicated with T1DM. Materials and methods. 64 patients with various forms of chronic tonsillitis in active period of disease observed during the study. Patients were divided into the following groups: 21persons with the compensate form of CT (CTC, 24 persons with the decompensate form of CT (CTD and 9 persons with the decompensate form of CT complicated with T1DM (CTD+ T1DM. The control group consisted of 15 apparently healthy persons. Concentrations of sIgA and IgA in the oropharyngeal secret were determined by the method of radial immune diffusion by Manchini. Lysozyme content was determined using the test system "Lysozyme" ("Reakompleks", Russia. Levels of lactoferrin and SLPI in the oropharyngeal secret of patients were evaluated using ELISA test systems of "BioChemMack", Russia. Patients of group CTC were divided into subgroups CTC1 and CTC2, depending on the applied treatment. Both subgroups treated with standard therapy for two weeks, on the fifteenth day of therapy patients of subgroup CTC2 received Respibron during 10 days by 1 tablet once a day and Licopid during 10 days by 1 mg once a day. Similarly patients of group CTD were divided into subgroups CTD1 and CTD2. Patients of subgroup CTD2 received therapy according to the scheme of CTC2. Patients of group CTD+ T1DM divided into subgroups CTD1+ T1DM and CTD2+ T1DM. Patients of

    The purpose of this study was to determine the prevalence of sinus opacification among dental paediatric patients. Two hundred and eight Cone Beam Computed Tomography (CBCT) scans of dental patients under the age of 18 were reviewed for sinus opacification. Patients with any sinus-related signs or symptoms were excluded. The overall prevalence of sinus opacification was 48.1%. The ethmoid (28.4%) and maxillary (27.8%) sinuses were most frequently affected. There were no statistically significant differences for both age and gender. The high prevalence of sinus opacification in asymptomatic children emphasizes the necessity of clinical correlation.

    Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female. It is one of the fibrous osseous lesions and should be differentiated from osteoma and ossifying fibroma. Radiographically, fibrous dysplasia showed "groundglass" bone appearance on CT scans with bone window. Histopathologically, it presents woven-type bone embedded in a cellular fibrous stroma without osteoblastic rimming. We presented a case of 25-year-old female with fibrous dysplasia in her right side ethmoid sinus. She visited to us with the chief complaint of right side headache since adolescence. The lesion was removed by endoscopic sinus surgery and pathology proved fibrous dysplasia. The patient was free of headache after operation. The advance of endoscopic sinus surgical technique, makes it an optimal method for the pathological diagnosis and treatment to avoid the cosmetic problems caused by external approach in limited paranasal sinus fibrous osseous lesions.

    To analyze the clinical patterns, etiologies, treatment, and outcome of cerebral venous sinus thrombosis (CVST) in 2 major cities of Saudi Arabia, Jeddah and Al-Baha. One hundred and eleven patients diagnosed as CVST were identified from the medical records at King Abdulaziz Medical City, Jeddah, and King Fahad Hospital, Al-Baha, Saudi Arabia, from January 1990 through November 2010. We retrospectively analyzed the data, compared it with local and international studies, and reviewed the literature. There were 92 adults and 19 children. Among adults, females predominated, while more boys were affected than girls. The mean age of onset was 29.5 years. The most common clinical presentations were headache, focal neurologic deficits, seizures, papilledema, and decreased level of consciousness. The main risk factors identified were pregnancy/ puerperium, antiphospholipid antibody syndrome, oral contraceptive pills, malignancy, and infections. Multiple sinuses were affected in 51 patients (45.9%). When a single sinus was involved, the superior sagittal sinus (24.3%) was the most common. Seventy-four patients recovered completely, 23 patients recovered partially, and 10 patients died. Bad prognostic factors included incurable co-morbid conditions, late presentation, and status epilepticus. Pregnancy/puerperium was the most common etiological factor in our series. Clinical features were similar to international series. Behcet`s disease was not a major etiological factor in our series. Most patients had involvement of multiple sinuses. Prompt treatment with anticoagulation resulted in complete or partial recovery in 87.4% of patients.

    Diseases of nose and paranasal sinuses can complicate to involve the orbit and other surrounding structures because of their close proximity. These diseases are usually infective or can be neoplastic in origin. Method: All the patients presenting in ENT or Eye Departments of Ayub Teaching Hospital during the one year study period who had complicated nose or paranasal sinus disease were included in the study. A detailed history and examination followed by CT scanning and laboratory investigations to assess the type and extent of the disease, was carried out. Results: Infections were the most common cause of complicated sinus disease 11 (75%). The rest of the 4 (25%) cases were tumours. 12 (80%) of the cases presented with proptosis. In 1 of these 12 cases, there was complete blindness. In 2 (13%) of the cases there was only orbital cellulitis. Two of these patients had facial swelling and 2 had nasal obstruction and presented as snoring. Two patients presented with history of weight loss and these patients had malignant tumour of the paranasal sinuses. One patient presented with early signs of meningitis. In 1 case sub periosteal scalp abscess (Pott's puffy tumour) was the only complication noted. Conclusion: Nose and paranasal sinus diseases can complicate to involve mostly the orbit, but sometimes brain, meninges and skull bones can also get involved. (author)

  20. Does evolutionary innovation in pharyngeal jaws lead to rapid lineage diversification in labrid fishes?

    Directory of Open Access Journals (Sweden)

    Wainwright Peter C

    2009-10-01

    Full Text Available Abstract Background Major modifications to the pharyngeal jaw apparatus are widely regarded as a recurring evolutionary key innovation that has enabled adaptive radiation in many species-rich clades of percomorph fishes. However one of the central predictions of this hypothesis, that the acquisition of a modified pharyngeal jaw apparatus will be positively correlated with explosive lineage diversification, has never been tested. We applied comparative methods to a new time-calibrated phylogeny of labrid fishes to test whether diversification rates shifted at two scales where major pharyngeal jaw innovations have evolved: across all of Labridae and within the subclade of parrotfishes. Results Diversification patterns within early labrids did not reflect rapid initial radiation. Much of modern labrid diversity stems from two recent rapid diversification events; one within julidine fishes and the other with the origin of the most species-rich clade of reef-associated parrotfishes. A secondary pharyngeal jaw innovation was correlated with rapid diversification within the parrotfishes. However diversification rate shifts within parrotfishes are more strongly correlated with the evolution of extreme dichromatism than with pharyngeal jaw modifications. Conclusion The temporal lag between pharyngeal jaw modifications and changes in diversification rates casts doubt on the key innovation hypothesis as a simple explanation for much of the richness seen in labrids and scarines. Although the possession of a secondarily modified PJA was correlated with increased diversification rates, this pattern is better explained by the evolution of extreme dichromatism (and other social and behavioral characters relating to sexual selection within Scarus and Chlorurus. The PJA-innovation hypothesis also fails to explain the most dominant aspect of labrid lineage diversification, the radiation of the julidines. We suggest that pharyngeal jaws might have played a more

    Although oropharyngeal candidiasis is associated with inhaled corticosteroid (ICS) usage, there is sparse data on the prevalence of posterior pharyngeal candidiasis in those without any detectable oral candidiasis on clinical examination. We systematically investigated the relationship between oral candidiasis on clinical examination and the presence of posterior pharyngeal candidiasis at bronchoscopy. We conducted a cross-sectional study on a convenience sample of 100 patients undergoing bronchoscopy at our institution. Patients were assessed for symptoms of and risk factors for candida infection and had an examination of their oropharynx for evidence of candidiasis before bronchoscopy. They subsequently had a detailed assessment for posterior candidiasis at bronchoscopy. We performed a posteriori subgroup analysis, which focused solely on those patients on ICS maintenance therapy. Median age was 54.7 (27-84) years, and 55 patients were male; 47 % of patients were on ICS, and 20 % of this cohort received recent oral corticosteroids. Twenty-eight percent of this convenience sample had posterior pharyngeal candidiasis; however, only 10.7 % (3/28) of these patients had clinically detectable oral candidiasis on clinical examination before bronchoscopy. Factors that were independently associated with the presence of pharyngeal candidiasis at bronchoscopy were OR (95 % CI) ICS usage 6.9 (2.5-19.2), particularly fluticasone usage 6.8 (2.62-17.9) and the presence of dysphonia 3.2 (1.3-8.0). In the subgroup analysis of ICS usage, posterior pharyngeal candidiasis was correlated with the presence of dysphonia but was not independently associated with fluticasone or budesonide dosage. This study demonstrates that posterior pharyngeal candidiasis in the absence of clinically overt oral candidiasis is frequent amongst ICS users. A history of ICS use, particularly fluticasone usage, as well as the presence of dysphonia are associated with posterior pharyngeal candidiasis at

Decreasing the score of patients with Centor values of 3 by one point for RLPP biosurveillance data into clinical guidelines for GAS pharyngitis and other communicable diseases should be considered to reduce missed cases when the contemporaneous incidence is elevated and spare unnecessary antibiotics when the contemporaneous incidence is low. Delivering epidemiologic data to the point of care will enable the use of real-time pre-test probabilities in medical decision-making.

    Group C streptococci (GCS) and group G beta-haemolytic streptococci (GGS) have caused well-documented epidemics of acute pharyngitis in children, but the importance of these organisms in causing endemic or sporadic pharyngitis is uncertain. The heterogeneity of GCS and GGS may obscure the role of certain subtypes, such as the large-colony-forming strains of group C (Streptococcus dysgalactiae subsp. equisimilis) or group G, in endemic pharyngitis. For a 1-year period, children (aged 6 months to 18 years) (n = 2085) who presented with pharyngitis to the children's hospital emergency department and two outpatient offices were enrolled in a cross-sectional study to ascertain the role of large-colony-forming GCS and GGS in acute pharyngitis. Control patients (n = 194) were children who presented to the same locations during the same time period with non-respiratory tract symptoms or to the orthopaedic cast clinic. Throat cultures were obtained by a standard reference method, and swabs were plated on Strep-Selective Agar. Lancefield grouping and species identification was performed on all beta-haemolytic isolates. In total, 65 (3%) large-colony-forming GCS and GGS strains were obtained from pharyngitis patients, and three (1.5%) were obtained from the control group (odds ratio 2.0; 95% confidence interval 0.6-6.1). The low isolation rate of large-colony-forming strains of GCS and GGS indicates that even if these organisms are associated with acute, sporadic pharyngitis in paediatric patients, they represent an unusual pathogen.

    The tonsils, oral cavity and faeces of 94 pigs at slaughter were sampled to assess the numbers of total aerobic bacteria, Enterobacteriaceae and Escherichia coli in the rectal content, tonsils and oral cavity of pigs at time of evisceration. Moreover, the prevalence, numbers and types of Salmonella spp. were determined. Mean numbers of Enterobacteriaceae in tonsils and the oral cavity differed between slaughterhouses. The proportion of Enterobacteriaceae relative to total aerobic bacteria differed between the different tissues, though large variations were observed between animals. Salmonella spp. were mostly detected in oral cavity swabs (n = 51, 54%), of which six samples were contaminated in numbers over 2.0 log CFU/100 cm 2 . Salmonella spp. were also recovered from 17 tonsillar tissue samples (18%) and 12 tonsillar swabs (13%). Out of the 29 rectal content samples from which Salmonella was recovered (31%), most were lowly contaminated, in the range between -1 and 0 log CFU/g. The predominant serotypes were S. Typhimurium and its monophasic variant, which were recovered from 33 and 13 pigs, respectively. In most cases, the same serotypes and MLVA profiles were found in pigs slaughtered during the same day, thus suggesting a common source of contamination. Copyright © 2017 Elsevier Ltd.

    Tonsillitis is a common illness in the childhood period. There are about 7,455,494 cases of tonsillitis in India per year. Tonsillitis can be compared with Tundikeri in Ayurveda. In the present study, Kanchnara Guggulu tablets and Pratisarana of Tankana-Madhu were selected. To evaluate the effect of Kanchnar Guggulu and Tankana-Madhu Pratisarana in the management of Tundikeri in children. In the present study, a total of 31 patients aged between 5 and 16 years attending the outpatient department of Kaumarbhritya Department and Shalakya Tantra Department were registered. Among them, 26 patients completed the treatment. Kanchnara Guggulu tablets were administered orally in Group A and in Group B, Pratisarana with Tankana-Madhu was done along with the oral administration of Kanchnara Guggulu tablets. The results showed that in Group A, 21.43% of patients got complete remission, 42.86% of patients got marked improvement and 35.71% of patients got moderate improvement. In Group B, 25% of patients got complete remission, 58.33% of patients got marked improvement and 16.67% of patients got moderate improvement. Both the groups showed highly significant results in all cardinal and associated features of Tundikeri . Kanchnara Guggulu and Tankana-Madhu Pratisarana are a safe and effective modality for the treatment of Tundikeri .

    Full Text Available Dysautonomia in Guillain-Barre syndrome (GBS rarely causes serious cardiovascular complications, such as sinus arrest. Miller Fisher syndrome (MFS is recognized as a variant of GBS. There have been few reports regarding the association between MFS and dysautonomia. We describe a case of a 68-year-old man with ophthalmoplegia, bulbar palsy, truncal ataxia, and areflexia. He was diagnosed with MFS because he exhibited the classical clinical triad and had elevated serum anti- GQ1b immunoglobulin G levels. A magnetic resonance imaging scan of his head was normal. His 24-hour Holter recording showed sinus arrest. He was treated with intravenous immunoglobulin, whereupon his symptoms gradually improved. This included the sinus arrest, which was considered a symptom of dysautonomia in MFS. Therefore, clinicians should be mindful of dysautonomia not only in GBS patients, but also in cases of MFS.

    Investigations into the distribution of sinus irrigations have been limited by labor-intensive methodologies that do not capture the full dynamics of irrigation flow. The purpose of this study was to validate the accuracy of a computational fluid dynamics (CFD) model for sinonasal irrigations through a cadaveric experiment. Endoscopic sinus surgery was performed on 2 fresh cadavers to open all 8 sinuses, including a Draf III procedure for cadaver 1, and Draf IIb frontal sinusotomies for cadaver 2. Computed tomography maxillofacial scans were obtained preoperatively and postoperatively, from which CFD models were created. Blue-dyed saline in a 240-mL squeeze bottle was used to irrigate cadaver sinuses at 60 mL/second (120 mL per side, over 2 seconds). These parameters were replicated in CFD simulations. Endoscopes were placed through trephinations drilled through the anterior walls of the maxillary and frontal sinuses, and sphenoid roofs. Irrigation flow into the maxillary, frontal, and sphenoid sinuses was graded both ipsilateral and contralateral to the side of nasal irrigation, and then compared with the CFD simulations. In both cadavers, preoperative and postoperative irrigation flow into maxillary, frontal, and sphenoid sinuses matched extremely well when comparing the CFD models and cadaver endoscopic videos. For cadaver 1, there was 100% concordance between the CFD model and cadaver videos, and 83% concordance for cadaver 2. This cadaveric experiment provided potential validation of the CFD model for simulating saline irrigation flow into the maxillary, frontal, and sphenoid sinuses before and after sinus surgery. © 2016 ARS-AAOA, LLC.

    Background and Purpose— Dysphagia is common after stroke, associated with increased death and dependency, and treatment options are limited. Pharyngeal electric stimulation (PES) is a novel treatment for poststroke dysphagia that has shown promise in 3 pilot randomized controlled trials. Methods— We randomly assigned 162 patients with a recent ischemic or hemorrhagic stroke and dysphagia, defined as a penetration aspiration score (PAS) of ≥3 on video fluoroscopy, to PES or sham treatment given on 3 consecutive days. The primary outcome was swallowing safety, assessed using the PAS, at 2 weeks. Secondary outcomes included dysphagia severity, function, quality of life, and serious adverse events at 6 and 12 weeks. Results— In randomized patients, the mean age was 74 years, male 58%, ischemic stroke 89%, and PAS 4.8. The mean treatment current was 14.8 (7.9) mA and duration 9.9 (1.2) minutes per session. On the basis of previous data, 45 patients (58.4%) randomized to PES seemed to receive suboptimal stimulation. The PAS at 2 weeks, adjusted for baseline, did not differ between the randomized groups: PES 3.7 (2.0) versus sham 3.6 (1.9), P=0.60. Similarly, the secondary outcomes did not differ, including clinical swallowing and functional outcome. No serious adverse device-related events occurred. Conclusions— In patients with subacute stroke and dysphagia, PES was safe but did not improve dysphagia. Undertreatment of patients receiving PES may have contributed to the neutral result.

    As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism.

    Full Text Available Although pathogens must infect differentiated host cells that exhibit substantial diversity, documenting the consequences of infection against this heterogeneity is challenging. Single-cell mass cytometry permits deep profiling based on combinatorial expression of surface and intracellular proteins. We used this method to investigate varicella-zoster virus (VZV infection of tonsil T cells, which mediate viral transport to skin. Our results indicate that VZV induces a continuum of changes regardless of basal phenotypic and functional T cell characteristics. Contrary to the premise that VZV selectively infects T cells with skin trafficking profiles, VZV infection altered T cell surface proteins to enhance or induce these properties. Zap70 and Akt signaling pathways that trigger such surface changes were activated in VZV-infected naive and memory cells by a T cell receptor (TCR-independent process. Single-cell mass cytometry is likely to be broadly relevant for demonstrating how intracellular pathogens modulate differentiated cells to support pathogenesis in the natural host.

    Full Text Available Background: As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH. Patients and Methods: A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients′ data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Results: Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1 belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years. The age group of 3-5 years had the highest (n = 40, 40% number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85% surgery performed on patients who had obstructive sleep apnea (OSA. The commonest (n = 6, 6% complication was haemorrhage, and only few (n = 3, 3% patients had blood transfusion. However, mortality was recorded in some (n = 3, 3% patients. Conclusion: This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion

    Swallowing impairment (dysphagia) is a common sequela in patients with motor neuron disease (MND). The purpose of this retrospective, observational pilot investigation was to characterize how pharyngeal swallowing mechanics are impacted in patients with MND using a comparison with healthy, non-dysphagic control group. Computational analysis of swallowing mechanics (CASM) was used to determine covariate biomechanics of pharyngeal swallowing from videofluoroscopic assessment in 15 patients with MND and 15 age- and sex-matched healthy controls. Canonical variant analysis with post hoc discriminate function analysis (DFA) was performed on coordinate data mapping functional muscle groups underlying pharyngeal swallowing. Differences in swallowing mechanics associated with group (MND; control), motor neuron predominance (upper; lower), onset (bulbar; spinal), and swallow task (thin, pudding) were evaluated and visualized. Pharyngeal swallowing mechanics differed significantly in patients with MND compared with healthy controls (D = 2.01, p mechanics by motor neuron predominance (D = 5.03, p mechanics of patients with MND differ from and are more heterogeneous than healthy controls. These findings suggest patients with MND may compensate reductions in pharyngeal shortening and tongue base retraction by extending the head and neck and increasing hyolaryngeal excursion. This work and further CASM investigations will lead to further insights into development and evaluation of targeted clinical treatments designed to prolong safe and efficient swallowing function in patients with MND.

  9. Introducing a Virtual Lesion Model of Dysphagia Resulting from Pharyngeal Sensory Impairment

    2018-01-01

    Full Text Available Background/Aims: Performing neurophysiological and functional imaging studies in severely affected patients to investigate novel neurostimulation techniques for the treatment of neurogenic dysphagia is difficult. Therefore, basic research needs to be conducted in healthy subjects. Swallowing is a motor function highly dependent on sensory afferent input. Here we propose a virtual peripheral sensory lesion model to mimic pharyngeal sensory impairment, which is known as a major contributor to dysphagia in neurological disease. Methods: In this randomized crossover study on 11 healthy volunteers, cortical activation during pneumatic pharyngeal stimulation was measured applying magnetoencephalography in two separate sessions, with and without pharyngeal surface anesthesia. Results: Stimulation evoked bilateral event-related desynchronization (ERD mainly in the caudolateral pericentral cortex. In comparison to the no-anesthesia condition, topical anesthesia led to a reduction of ERD in beta (13-30 Hz and low gamma (30-60 Hz frequency ranges (p<0.05 in sensory but also motor cortical areas. Conclusions: Withdrawal of sensory afferent information by topical anesthesia leads to reduced response to pneumatic pharyngeal stimulation in a distributed cortical sensorimotor network in healthy subjects. The proposed paradigm may serve to investigate the effect of neuromodulatory treatments specifically on pharyngeal sensory impairment as relevant cause of neurogenic dysphagia.

    The objective of this study was to determine the seasonal pattern of group A streptococcal pharyngitis in children attended at a hospital emergency department in the Mediterranean island of Mallorca (Spain), and its association with meteorologic factors and schooling. We conducted a retrospective review of the medical records of children aged 1-15 years with a diagnosis of Streptococcus pyogenes pharyngitis between January 2006 and December 2011. The number of S. pyogenes pharyngitis was correlated to temperature, humidity, rainfall, atmospheric pressure, wind speed, solar radiation, and schooling, using regression and time series techniques. A total of 906 patients (median, 4 years old) with S. pyogenes pharyngitis, confirmed by throat culture, were attended during the study period. A seasonal pattern was observed with a peak activity in June and a minimum in September. Mean temperature, solar radiation, and school holidays were the best predicting variables ( R 2 = 0.68; p a clear seasonality predominating in springtime, and an association with mean temperature, solar radiation, and schooling was observed. The resulting model predicted 68 % of S. pyogenes pharyngitis.

    Full Text Available Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation. Conclusion. Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery.

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Since an accurate description on the pathophysiology of the nasal cavity and paranasal sinus (PNS) was established, a detailed evaluation of their anatomic and pathologic status, especially of the ostiomeatal unit, has become important, and computed tomography (CT) has increasingly been used for evaluating chronic sinusitis. This study was undertaken to assess the value of CT in chronic or recurrent paranasal sinusitis and to ascertain the theory of rhinogenic origin as the pathophysiologic basis of sinusitis. We retrospectively analyzed the PNS CT findings of 108 patients with chronic or recurrent sinusitis. The CT scan were obtained in thin-section (3mm or 5mm) coronal and axial planes after contrast medium administration. With respect to the location of the sinusitis, the anterior ethmoid sinus was involved in 98 (91%), maxillary sinus in 93 (86%), frontal sinus in 60 (56%), posterior ethmoid sinus in 35 (32%), and sphenoid sinus in 32 cases (30%). CT finding of the sinusitis consisted of sinus opacification (74%), mucoperiosteal thickening (69%), mucosal enhancement (36%), air-fluid level (18%), and bony wall thickening (11%). Complications included retention cysts (29%), mucoceles (8%), and orbital cellulitis (1%). Obstruction of the ostiomeatal unit was noted in 104 cases (96%), which were composed of inflammatory process, nasal polyps, concha bullosae, inverting papillomas, paradoxic middle turbinates, severe septal deviations, and large ethmoidal bulla. Of the 17 cases with a past history of Caldwell-Luc operation, 15 cases showed obstruction of the ostiomeatal units. We concluded the CT was a very useful modality for evaluating chronic or recurrent sinusitis and for demonstrating the finely detailed pathologic anatomy of the nasal cavity and paranasal sinuses.

    Objective: To study the imaging features of meningiomas of ethmoid sinuses. Methods: Six cases of meningiomas of ethmoid sinuses verified pathologically were analyzed retrospectively. Results: CT scans of 6 cases exhibited huge cystic masses (n = 3), huge cystic-solid masses (n = 2), huge solid mass (n = 1). The cystic walls were remarkable osteosclerosis. The density of solid masses were homogeneous, or heterogeneous with calcifications and cystic changes, and prominent contrast-enhancement. MR images of 1 case (1/6) showed a cystic-solid mass, the cystic portion was high signal intensity on T 2 WI and low signal intensity on T 1 WI, while the solid mass was iso-signal intensity on T 1 WI and T 2 WI. The solid portion was enhanced. X-ray plain films of 3 cases (3/6) displayed ethmoid sinuses enlargement and high density. Conclusion: For the meningiomas of ethmoid sinuses, CT finding was specific, MRI was helpful in differential diagnosis, and X-ray plain films was of no qualitative value

    Full Text Available Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative metronomic chemotherapy between August 2011 and August 2014. The demographic details, symptomatology, previous treatment details, indication for palliative chemotherapy, response to therapy, and overall survival (OS details were extracted. SPSS version 16 was used for analysis. Descriptive statistics have been performed. Survival analysis was done by Kaplan-Meier method. Results: Five patients had received metronomic chemotherapy. The median age was 60 years (range 37-64 years. The proportion of patients surviving at 6 months, 12 months, and 18 months were 40%, 40%, and 20%, respectively. The estimated median OS was 126 days (95% confidence interval 0-299.9 days. The estimated median survival in patients with an event-free period after the last therapy of <6 months was 45 days, whereas it was 409 days in patients with an event-free period postlast therapy above 6 months (P = 0.063. Conclusion: Metronomic chemotherapy in carcinoma maxillary sinus holds promise. It has activity similar to that seen in head and neck cancers and needs to be evaluated further in a larger cohort of patients.

    To demonstrate a cost-effective, quick, and easily reproducible three-dimensional sticky note model to enhance the understanding and conceptualization of the geometry and steps of the pharyngeal flap and sphincter pharyngoplasty. The method involves making specified incisions and rearrangements of readily available components, including disposable clear plastic cups, yellow and pink sticky notes, and white paper. Once assembly is complete, further incisions and remodeling are performed to simulate a pharyngeal flap or sphincter pharyngoplasty. The cost of the materials to make one model was $0.94. Average construction time was less than 10 min. This three-dimensional model is an efficient, interactive, and simple visual aid to teach surgical trainees the geometry and steps of the pharyngeal flap and sphincter pharyngoplasty.

    To describe the molecular epidemiology of emm types associated with circulating pharyngeal group A streptococcus (GAS) isolates in Auckland, New Zealand. GAS isolates were collected over a 10-day period from a community pathology provider in Auckland. PCR analysis and sequencing of the emm gene was performed at the Institute of Environmental Science and Research. A total of 52 emm types were identified from 278 GAS isolates. The three most common emm types were emm1, emm89 and emm12. Overall, the experimental 30-valent GAS M protein vaccine covered 19 / 52 (37%) of emm types in our study. Our study provides baseline data on the circulating pharyngeal GAS emm types in Auckland. Future clinical and molecular surveillance of GAS pharyngitis is essential in the context of ongoing GAS vaccine development.

    Dermal sinus tracts are remnants of incomplete neural tube closure. Dermal sinus tracts in the spine range from asymptomatic pits to tracts with significant disease. Congenital spinal dermal sinus tract can produce significant morbidity if not adequately managed. Spinal subdural abscess caused by the spread of an infection within the dermal sinus tract is rare in children. We now described a 3-year-old male who presented with extensive spinal subdural abscess resulting from dermal sinus tract that was low-lying in the sacral area.

    Full Text Available Introduction: A few patients with asymmetric palatine tonsils have lymphoma; but most lymphomas in palatine tonsils evolve with tonsillar asymmetry. Objective: To report the profile of patients and histopathological changes in patients submitted to adenotonsillectomy/tonsillectomy with disproportional palatine tonsils. Method: Retrospective study based on data analysis from the Pathologic Anatomy Service Database and in the review of reports of patients submitted to adenotonsillectomy and tonsillectomy with palatine tonsils asymmetry during the period from October 1999 through October 2009 at the Clinical Hospital (HC of the Federal University of Paraná (UFPR. Results: 50 patients took part, aged between 3 to 53 years old, mean age of 14.05 years. The anatomopathological exam confirmed 48 patients (96% with lymphoid hyperplasia and 2 cases of lymphoma (4%. These included men aged from 40 to 53 yeas with complaint of unilateral increase of the tonsil, one of whom had other symptoms (asthenia and weight loss. Upon physical examination: tonsils disproportion without involvement of other organs or lymph nodes. Conclusion: Our study is according to the literature as regards the fact the lymphomas are more common in men, the patient is the first one to notice the increase in volume and the asymmetry is larger than 2 degrees between palatine tonsils in cases of lymphoma. Although it is rare, even in the presence of differences, there are chances for the asymmetry to evolve to a malignant profile. The need for anatomopathological evaluation of a part must be considered along with other clinical data that suggests a malignant profile.

    Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

    Genital ambiguity is a very common phenomenon in disorders of sex development (DSD). According to the Chicago Consensus 2006, feminizing genitoplasty, when indicated, should be performed in the most virilized cases (Prader III to V). Advances in the knowledge of genital anatomy in DSD have enabled the development and improvement of various surgical techniques. Mobilization of the urogenital sinus (MUS), first described by Peña, has become incorporated by most surgeons. However, the proximity of the urethral sphincter prompts concern over urinary incontinence, especially for full mobilization of the urogenital sinus. To retrospectively evaluate the short-term surgical results of feminizing genitoplasty with total mobilization of the urogenital sinus in patients with DSD. Review of medical records of all patients undergoing feminizing genitoplasty with mobilization of the urogenital sinus. We evaluated the rates of complications from surgery and of urinary incontinence, as well as cosmetic results, according to the opinion of the surgeon and the family. A total of 8 patients were included in the study. The mean age at surgery was 51months. Congenital adrenal hyperplasia (CAH) was diagnosed in six patients, and gonadal dysgenesis in the other two. The vagina was separated from the urethra, with suitable distance in all cases. No patient had urinary incontinence after surgery. The mean follow-up of patients was. 20months (3-56months). In all cases, surgeons recorded being satisfied with the aesthetic result of post-surgical genitalia. The family was recorded as satisfied with the aesthetic result of the genitalia after surgery. In every case, there was no need for a second surgical procedure. The total mobilization of the urogenital sinus is a feasible and safe technique. The technique permits good cosmetic results, and urinary incontinence is absent. Therapeutic study. Level III. Copyright © 2017 Elsevier Inc. All rights reserved.

    Nasofrontal dermal sinuses are very rare and generally occur in children. This congenital malformation can be revealed by midface swelling, which can be complicated by local infection or neuromeningitis. Such complications make the dermal sinus a life-threatening disease. Two cases of nasofrontal dermal sinuses are reported in this work. The first case is an 11-month-old girl who presented with left orbitonasal soft tissue swelling accompanied by inflammation. Physical examination found fever, left orbitonasal thickening, and a puncture hole letting out pus. Computed tomography revealed microabscesses located at the left orbitonasal soft tissues, a frontal bone defect, and an intracranial cyst. Magnetic resonance imaging showed the transosseous tract between the glabella and the brain and affirmed the epidermoid nature of the intracranial cyst. The second case is a 7-year-old girl who presented with a nasofrontal non-progressive mass that intermittently secreted a yellow liquid through an external orifice located at the glabella. MRI revealed a cystic mass located in the deep layer of the glabellar skin related to an epidermoid cyst with a nasofrontal dermal sinus tract. In both cases, surgical excision was performed, and pathological confirmation was made for the diagnoses of dermal sinuses. The postoperative course was favorable. Through these cases, the authors stress the role of imaging methods in confirming the diagnosis and looking for associated cysts (dermoid and epidermoid) to improve recognition of this rare disease. Knowledge of the typical clinical presentations, imaging manifestations, and most common sites of occurrence of this malformation are needed to formulate a differential diagnosis.

    We attempted to investigate the role of nasal allergy in sinusitis to elucidate whether it results from an immediate-type allergic reaction of the sinus mucosa or from allergic edema-induced sinus ostial obstruction. Forty-two patients with chronic sinusitis were selected for allergen skin tests, measurements of serum total and specific IgE, and sinus tissue-specific IgE. The data were then correlated to examinations of nasal mucosal scrapings and histopathology of the sinus mucosa. We found that serum levels of total IgE and house dust mite-specific IgE antibodies were significantly higher in patients (n = 12) allergic to house dust than in the nonatopics (n = 30; p less than 0.0001). There was no difference in the sinus tissue-specific IgE antibody. Eosinophils and basophilic cells in epithelial scrapings from the inferior turbinates, assessed by Hansel staining, were high in 66.7% and 50% of the atopic patients, respectively, and 36.7% and 26.7% of the nonatopics, respectively. The rates were influenced by the existence of infection and nasal polyps. The increase in eosinophils, mast cells and plasma cells, assessed by histopathologic examination, were not prevalent in the sinus mucosa of atopic patients. It is concluded that nasal allergy may be a predisposing factor to sinusitis and that the pathologic change of the sinus mucosa is mainly secondary, due to sinus ostial obstruction.

    Malignant tumours of maxillary sinus are rare. They are usually diagnosed in the late stages when they perforate the sinus walls. The presence of large air space in the maxillary sinus facilitates asymptomatic growth of the sinus malignancy. The clinical presentation of these tumours depends on the sinus wall involved by the disease. The medial wall is usually the first to become eroded, leading to nasal obstruction, epistaxis or discharge. Rarely, symptoms of maxillary sinus carcinoma can resemble dental infection and the affected patients may visit dental clinic seeking treatment. This report presents a case of carcinoma of maxillary sinus mimicking odontogenic infection. Computed tomographic findings explained the reason for the present lesion to masquerade as an inflammatory condition. The importance of advanced imaging modalities for prompt identification of such lesions is discussed.

    Full Text Available In the therapy of decompensated form of chronic tonsillitis (CT were used as immunomodulatory agents IRS and Ismigen. These bacterial lysates differ in the bacterial setting, the method of preparation (chemical, mechanical and the method of application.Rheumatoid arthritis (RA is one of the important factors that could significantly complicate the therapy of chronic tonsillitis. RA is a chronic immune inflammatory disease that progressively affects connective tissue mostly of the peripheral joints and it has a wide range of extra-articular manifestations. The aim of our study was to explore the dynamics of immunologic indicators during the active disease and treatments in patients with decompensate form of chronic tonsillitis, including tonsillitis complicated with RA. Materials and methods. 33 patients with decompensate form of chronic tonsillitis in active period of disease observed during the study. Patients were divided into the following groups: 24 persons with the decompensate form of CT, 9 persons with the rheumatoid arthritis and 9 persons with the decompensate form of CT complicated with RA in remission stage. The control group consisted of 15 apparently healthy persons. Concentrations of serum IgA, IgM, IgG were determined by the method of radial immune diffusion by Manchini. Levels of sIgA, IFN – γ and rheumatoid factor in the blood serum of patients were evaluated using ELISA test systems of "Vector-best". Patients of group CTD (with decompensate form of chronic tonsillitis were divided into subgroups CTD1 and CTD2, depending on the applied treatment. Both subgroups treated with standard therapy for two weeks and received Derynat during 1 month by 2 drops in each nostril twice a day. After 30 days of the standard therapy beginning the subgroup CTD1 patients received IRS 19 during two weeks, one intranasal inhalation in each nostril 3 times a day.

    Antioxidants can play a significant role in chronic inflammatory process. The aim of this study was to evaluate the content of selenium (Se), zinc (Zn), copper (Cu), and total antioxidant status (TAS) of patients with chronic tonsillitis (CT). The study group consisted of 84 patients with CT from 18 to 62 years old and the control group of 67 healthy people aged 19-65 years. Se, Zn, and Cu concentration in serum samples were determined by atomic absorption spectrometry. Serum TAS was measured spectrophotometrically, using the test by Randox Laboratories-Us Ltd. The mean content of Se and Zn in the serum of patients with CT (61.122 ± 12.73 μg/L, 0.887 ± 0.26 mg/L, respectively) was lower compared to the control group (77.969 ± 12.73 μg/L, 0.993 ± 0.32 mg/L, respectively). The mean serum concentration of Cu in patients with CT (1.219 ± 0.35 mg/L) was higher compared to its serum concentration in healthy people (1.033 ± 0.37 mg/L). Serum TAS of patients with CT (1.171 ± 0.33 mmol/L) was lower in comparison with healthy volunteers (1.333 ± 0.42 mmol/L). The serum concentration of Se, Zn, and TAS in patients with CT was lower, whereas the concentration of Cu was higher compared to healthy volunteers. Smoking has an influence on reducing the concentration of Se and TAS of patients with CT.

  19. Angiosarcoma: a case report of gingival disease with both palatine tonsils localization

    Full Text Available Angiosarcomas are one of the rarest subtypes of sarcomas; those are malignant vascular tumors arising from vascular endothelial cells. Occurrence of intra-oral angiosarcoma is extremely rare (0.0077% of all cancers in Europe. We present here, to our knowledge, the first case of a 83-year-old man with gingival and both palatine tonsils localization of a grade-two angiosarcoma discovered after a two months history of a painful lesion followed by hematoma and spontaneous bleeding. Chemotherapy with paclitaxel and hemostatic radiotherapy were inefficient and he died seven months after the first symptoms. It is essential to use the vascular markers, such as CD34, CD31, ERG and FLI1, for a correct histological diagnosis, which remains difficult because it displays a wide range of morphological appearances and multiple patterns may be present in the same tumor. The main prognostic factors are chronic pre-existing lymphedema and tumor size greater than five centimeters. Malignancy grade and stage classification should be provided in all cases in which this is feasible because of predictive meaning. When possible, wide surgical resection with negative margins remains the cornerstone for the treatment of localized angiosarcomas, but despite the improvement of surgical techniques the prognosis is poor with more than half of patients died within the first year. Adjuvant radiotherapy is the standard treatment of high–grade (two and three, deep lesions, regardless of size, because it improved the local recurrence-free survival. For advanced disease, if possible, metastasectomy should be considered. The first-line chemotherapy with doxorubicin or paclitaxel should be discussed compared to best supportive care according to patient comorbidities and preference.

    As tissue engineering and regenerative medicine have evolved recently, stem cell therapy has been investigated in the field of impaired wound healing. Several studies have reported that mesenchymal stem cells derived from various tissues including bone marrow and adipose tissue can exert the regenerative efficacy in the wound healing. Previously, we have demonstrated the isolation and characterization of tonsil-derived mesenchymal stem cells (TMSCs) with excellent proliferative property. In the present study, we aimed to evaluate the regenerative efficacy of TMSCs in the wound healing process. Two distinct cutaneous surgical defects were generated in the dorsum of mice. Each wound was treated with TMSCs or phosphate-buffered saline (PBS), respectively. After sacrifice, the skin and subcutaneous tissues around the surgical defect were harvested and assessed for inflammation, re-epithelialization, dermal regeneration, and granulation tissue formation. The administration of TMSCs into wound beds significantly promoted the repair of surgical defects in mice. Especially, TMSCs efficiently contributed to the attenuation of excessive inflammation in the surgical lesion, as well as the augmentation of epidermal and dermal regeneration. To elucidate the underlying mechanisms, TMSCs were analyzed for their potency in immunomodulatory ability on immune cells, stimulatory effect on the proliferation of keratinocytes, and fibroblasts, as well as the regulation of fibroblast differentiation. TMSCs inhibited the non-specific or T-cell-specific proliferation of peripheral blood mononuclear cells, as well as the M1 polarization of macrophage-like cells. Moreover, TMSCs augmented the proliferation of skin-constituting fibroblasts and keratinocytes while they suppressed the differentiation of fibroblasts into myofibroblasts. Taken together, our findings demonstrate the regenerative potential of TMSCs in wound healing process through the regulation on inflammation, proliferation

    We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

    We report a case of sphenoid sinusitis which could be diagnosed by orbital CT after detecting Strepotococcus pneumoniae from blood culture. A previously healthy 47 year-old Japanese male was admitted to our hospital with severe left-sided headache of 2 days duration. From 9 days before hospitalization (1st day), the patient complained of cough and sputum. On physical examination, his neck was supple and his temperature was 38.3 degrees C. The rest of the examination was normal. A chest radiograph, sinus radiograph, and head computed tomographic (CT) scan without contrast material disclosed no abnormalities. Lumbar puncture was done and cerebrospinal fluid was clear and cell counts and the levels of glucose and protein were normal. The peripheral white blood cell count was 14,400/fl, and the C-reactive protein level was 9.6 mg/dl. After blood, urine, pharyngeal mucus and cerebrospinal fluid cultures were obtained, empirical antibiotic therapy with 2 gms of piperacillin twice daily was begun. He complained sever left-sided retro-orbital headahe on the next day too. The lumbar puncture and head CT scan with contrast material was done again but gave no diagnostic clues. The examinations by the otolaryngologist, ophthalmologist and dentist found no abnormal findings. On the 3rd hospitalized day, Strepotococcus pneumoniae was detected from the blood culture taken on the 1st hospitalized day. A CT scan focused on orbita was done and revealed a low density area of the left sphenoid sinus. The dose of piperacillin was increased to 4 gms twice daily and continued for 24 days. The patient's headache improved and piperacillin was changed to oral levofloxacin 100 mg, three times daily on the 26th day. The medication was stopped on the 73th day. Isolated sphenoid sinusitis is rare, but crtitical complications such as cranial nerve involvement, brain abscess, and bacterial meningitis may happen. It is necessary to also think of sphenoid sinusitis in practices of patients with

    Yersiniosis is the third most common reported zoonoses in Europe, with Y. enterocolitica and Y. pseudotuberculosis responsible for 98.66% and 0.94% of the confirmed human cases in 2013. From June 2013 to October 2014, 201 pigs at slaughter belonging to 67 batches were tested for Y. enterocolitica and Y. pseudotuberculosis in tonsils. Diaphragm muscle samples were tested for antibodies against Yersinia by a commercially available ELISA test. Y. enterocolitica 4/O:3 was detected in 55/201 pig tonsils (27.4%; 95% CI 23.1-37.1). The positive pigs came from 38/67 batches (56.7%) and were reared in 36/61 farms (59.0%). There was no statistical difference between farrow-to-finish and finishing farms. The mean count of Y. enterocolitica was 3.56±0.85log10CFU/g with a minimum of 2.0log10CFU/g and a maximum of 4.78log10CFU/g. Y. pseudotuberculosis was isolated from 4/201 pig tonsils (2.0%; 95% CI 0.0-4.5). Three isolates belonged to serotype O:3 and one to serotype O:1. The positive pigs belonged to 4/67 batches (6.0%) and came from finishing farms only. Y. pseudotuberculosis could be enumerated in one sample only (4.27log10CFU/g). The ELISA test demonstrated that 56.1% of the meat juice samples were positive for Yersinia antibodies. Serological positivity was found in 67.9% (36/53) of the Y. enterocolitica- and 75.0% (3/4) of the Y. pseudotuberculosis positive pigs. A significant association was found between serological results and the presence of Y. enterocolitica in tonsils (OR=1.97, p=0.044). All the Y. enterocolitica 4/O:3 isolates were susceptible to amoxicillin-clavulanic acid, gentamicin, ceftazidime, ertapenem and meropenem, 94.5% to cefotaxime, 89.1% to kanamycin and 78.2% to tetracycline. The highest resistance rates were observed for ampicillin (100%), sulphonamides (98.2%) and streptomycin (78.2%). Y. pseudotuberculosis strains were sensitive to all the antimicrobials tested, i.e. amoxicillin, amoxicillin/clavulanic acid, azithromycin, cephalothin, cefoxitin

    Full Text Available Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review. Previous meta-analysis showed that survival rates of implants placed in grafted maxillary sinuses had similar survival rates whether autogenous, allogenous, or alloplastic grafts were used. This paper aims to review scientific data on the direct sinus elevation technique without use of any grafting material, volume of new bone formed, and also mechanism behind this technique. Articles were searched from 1997 to October 2014 in PubMed, Google Scholar, and Cochrane CENTRAL. The study eligibility criteria were (1 direct sinus lift procedure without any graft material during implant placement and (2 human or animal studies with a minimum follow-up of 6 months or more. Two authors independently scrutinized the literature and if any controversy was raised, third author's opinion was sought to arrive at a mutual consensus for including the study in the review. Due to the heterogeneity across all studies in all study designs, the data were not pooled and a meta-analysis was not performed. Taking into consideration all factors reviewed in this regard along with the outcomes, the direct sinus lift technique without grafting can be suggested as a viable treatment option keeping in mind the limitations involved. The average bone gain was seen across all studies ranging from 2.37 to 10 mm and with an implant survival rate ranging from 79

    1995-01-01

    In order to isolate ActinobacillIus pleuropneumoniae from mixed bacterial flora a selective and indicative medium was developed. The optimal concentrations of antibiotics were determined for selective chocolate agar (S-TSA) and selective blood agar (S-MBA) using a set of 25 strains of A....... pleuropneumoniae. Following optimization of the media 96 isolates of A. pleuropneumonine were tested on S-TSA and S-MBA. For isolation of A. pleuropneumoniae from 101 pig tonsils collected at slaughter the S-MBA proved significantly better than both S-TSA and the two non-selective agars tested. Furthermore...

    Several experimental studies have shown osteitis after the onset of sinusitis, supporting the idea that bone involvement could participate in the dissemination and perpetuation of this inflammatory disease. However, procedures commonly performed for the induction of sinusitis, such as antrostomies, can trigger sinusitis by themselves. To evaluate osteitis in an animal model of sinusitis that does not violate the sinus directly and verify whether this is limited to the induction side, or if it affects the contralateral side. Experimental study in which sinusitis was produced by inserting an obstructing sponge into the nasal cavity of 20 rabbits. After defined intervals, the animals were euthanized and maxillary sinus samples were removed for semi-quantitative histological analysis of mucosa and bone. Signs of bone and mucosal inflammation were observed, affecting both the induction and contralateral sides. Statistical analysis showed correlation between the intensity of osteitis on both sides, but not between mucosal and bone inflammation on the same side, supporting the theory that inflammation can spread through bone structures, regardless of mucosal inflammation. This study demonstrated that in an animal model of sinusitis that does not disturb the sinus directly osteitis occurs in the affected sinus and that it also affects the contralateral side.

    To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm 3 , respectively. There was a significant sex difference in the sinus volume (p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p<0.0001). In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

    The authors studied the epidemiology of pharyngitis in children and evaluated the contribution of a rapid streptococcal test. This prospective study was conducted from June 2007 to May 2008 in a primary health care institution (Policlinique de la Caisse Nationale de Sécurité Sociale) in Tunisia. Clinical findings were recorded; throat swabs were performed, and a rapid streptococcal test was made. Five hundred and four children were included in this study. The mean age was 5 years and 8 months. Culture was positive for group A streptococcus in 166 cases (32.9 %). Group A streptococcus was more frequently isolated in children aged 5 to 8 years. There was no difference in clinical features between groups of streptococcal and non-streptococcal pharyngitis. The sensitivity and specificity of the rapid test were respectively 93.2 and 95.3 %. Pharyngitis was of bacterial origin in one third of cases; among these, group A streptococcus was the most frequent bacterium. The rapid test is a quick and reliable tool for the diagnosis of pharyngitis and hence an appropriate treatment. Copyright 2009 Elsevier Masson SAS. All rights reserved.

    Biomarkers that predict clinical response, tumor recurrence or patient survival are severely lacking for most cancers, particularly for oral and pharyngeal cancer. This study examines whether gene-promoter methylation of tumor DNA correlates with survival and recurrence rates in a population of patients with oral or pharyngeal cancer. The promoter methylation status of the DNA repair gene MGMT and the tumor suppressor genes CDKN2A and RASSF1 were evaluated by methylation-specific PCR in 88 primary oral and pharyngeal tumors and correlated with survival and tumor recurrence. Quantitative MGMT methylation was also assessed. 29.6% of the tumors presented with MGMT methylation, 11.5% with CDKN2A methylation and 12.1% with RASSF1 methylation. MGMT promoter methylation was significantly associated with poorer overall and disease-free survival. No differences in methylation status of MGMT and RASSF1 with HPV infection, smoking or drinking habits were observed. A significant inverse trend with the amount of MGMT methylation and overall and disease-free survival was observed (p trend = 0.002 and 0.001 respectively). These results implicate MGMT promoter methylation as a possible biomarker for oral and pharyngeal cancer prognosis. The critical role of MGMT in DNA repair suggests that defective DNA repair may be correlative in the observed association between MGMT promoter methylation and tumor recurrence. Follow-up studies should include further quantitative MSP-PCR measurement, global methylation profiling and detailed analysis of downstream DNA repair genes regulated by promoter methylation

    To compare clinical and bacteriologic responses to intramuscular benzathine penicillin G (BPG) and single dose of amoxicillin in Group A streptococcal (GAS) pharyngitis. This study included 571 children from 6 to 15 years old age, with pharyngitis, who were admitted to 45 elementary and guidance schools from 7 regions of Education Organization in North-East of Iran, Mashhad. They were screened for enrollment and if he/she presented pharyngitis with clinical criteria of sore throat, erythema, exudate and tender or enlarged anterior cervical lymph nodes. Exclusion criteria included reports of antibiotic use, negative throat culture for GAS and history of allergy to the drugs. Clinical and bacteriologic responses to BPG and once daily orally amoxicillin were considered and compared. In the amoxicillin group, treatment failure was more than the penicillin group (18.9% vs. 6.4%, respectively) but the difference was not statistically significant (p amoxicillin. Our study was in line with studies comparing the two drugs. The results show that once-daily therapy with amoxicillin is as effective as intramuscular benzathine penicillin G for the treatment of GAS pharyngitis, but penicillin was significantly more effective in reducing exudate and concurrent signs vs. amoxicillin.

    Full Text Available This exploratory study of Jordanian and Moroccan Arabic (JA and MA aims to evaluate whether pharyngealization is associated with an epilaryngeal constriction which causes ‘retraction’ and tense voice quality in surrounding vowels, following the Laryngeal Articulator Model (LAM (Esling, 2005. Twenty male speakers (10 per dialect produced vowels preceded by /d or dˤ/. Thirteen acoustic correlates obtained at the onset and midpoint were used to assess this type of constriction. A predictive modeling approach was used; starting with Bayesian Generalized Linear Mixed Effects modeling followed by Conditional Random Forest for classification. Vowels in the pharyngealized context were more open (higher F1, Z1-Z0, more back (lower F2, higher Z3-Z2, more compact (lower Z2-Z1, and showed spectral divergence (higher Z3-Z2. Voice quality results showed these vowels to be produced with a tense voice. High classification rates of 93.5% for JA and 91.1% for MA were obtained and variable importance score showed formant-based measures outperform voice quality ones. This suggests pharyngealization has ‘retraction,’ with a 'back and down 'gesture, as a primary correlate followed by [+CONSTRICTED GLOTTIS]. The implications of these results provide strong support for LAM, the feature [+CET], and the use of the epilarynx to describe pharyngealization.

    Streptococcal toxic shock syndrome (STSS) is a re-emerging infectious disease in Japan and many other developed countries. Epidemiological studies have revealed that the M1 serotype of Streptococcus pyogenes is the most dominant causative isolate of STSS. Recent characterization of M1 isolates revealed that the mutation of covS, one of the two-component regulatory systems, plays an important role in STSS by altering protein expression. We analyzed the M1 S. pyogenes clinical isolates before or after 1990 in Japan, using two-dimensional gel electrophoresis (2-DE) and pulsed-field gel electrophoresis (PFGE). PFGE profiles were different between the isolates before and after 1990. Markedly different profiles among isolates after 1990 from STSS and pharyngitis patients were detected. Sequence analysis of two-component regulatory systems showed that covS mutations were detected not only in STSS but also in three pharyngitis isolates, in which proteins from the culture supernatant displayed the invasive type. The mutated CovS detected in the pharyngitis isolates had impaired function on the production of streptococcal pyrogenic exotoxin B (SpeB) analyzed by 2-DE. These results suggest that several covS mutations that lead to the malfunction of the CovS protein occurred even in pharyngeal infection.

  1. Anatomy of the bucco-pharyngeal cavity of Salminus brasiliensis (Cuvier, 1817 (Pisces, Characidae, Salmininae

    Directory of Open Access Journals (Sweden)

    Eliane Menin

    2006-03-01

    Full Text Available The bucco-pharyngeal cavity of Salminus brasiliensis, an ichthyophagous species of fresh water, is anatomically adapted to predation. The wide buccal rift, the oral-aboral enlargement of the buccal cavity and the reduced thickness of the pharyngeal mastigatory apparatus favor the capture and deglutition of larger prey. In function of the oral and pharyngeal dentition type, pre-digestive food preparation does not occur. The pointed and curved teeth, together with the tongue which is relatively mobile, prevent the prey’s escape from the buccopharyngeal cavity. The passage of the food is facilitated by the absence of pronounced folds in the mucous membrane of this cavity and by the disposition of the oral and pharyngeal teeth. The characteristics of flat and thin lips, developed oral dentition, relatively mobile tongue, mucous membrane without folds, pharynx with denticules disposed in dentigerous areas and plates, and short and sharp gill-rackers are anatomical adaptations which are shared by S. brasiliensis and other ichthyophagous Characiformes species such as Salminus maxillosus, Salminus hilarii, Hoplias malabaricus, Hoplias lacerdae, Acestrorhynchus lacustris and Acestrorhynchus britskii. However, different to the mentioned species, except other Salmininae, S. brasiliensis possesses oral teeth of an unique type, present only in the jawbones and distributed in two series.

    Cavernous sinus syndrome (CSS) is a rare condition characterised by ophthalmoplegia, proptosis, ocular and conjunctival congestion, trigeminal sensory loss and Horner's syndrome. These signs and symptoms result from the involvement of the cranial nerves passing through the cavernous sinus. We report the case of a 53-year-old man with a history of daily stabbing headache associated with dizziness, progressive blurred vision, right ocular pain, ptosis and ophthalmoplegia. After working up the patient, a meningioma was identified as the cause of the CSS. Despite advances in neuroimaging techniques, in some cases, the aetiology of CSS remains difficult to determine. We highlight the clinical and radiological features of a meningioma, one of the causes of CSS. Early diagnosis and treatment of CSS play a key role in a better prognosis. 2015 BMJ Publishing Group Ltd.

    Full Text Available Lateral sinus thrombosis (LST is usually occurs as a complication of middle ear infection .The involvement of lateral sinus during the course of ear infection was a well known complication in preantibiotic days .The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment. Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.

    During sedation for upper gastrointestinal endoscopy, oxygen delivery via a nasal cannula is often necessary. However, the influences of the oxygen delivery route and breathing pattern on the F(IO2) have not been thoroughly investigated. The aim of this simulation study was to investigate the difference in the F(IO2) with a pharyngeal cannula versus nasal cannula during high- or low-tidal volume (V(T)) ventilation and open- or closed-mouth breathing. Six healthy volunteers were asked to breathe using 2 patterns of ventilation (high or low V(T)) via a sealed face mask connected to an endotracheal tube that was retrogradely inserted into the trachea of a mannequin. The mannequin also had a pharyngeal or nasal cannula inserted into the pharynx or attached to the nose, through which oxygen (2 or 5 L/min) was delivered. The mouth of the mannequin was kept open or closed by packing. We measured the F(IO2) of every breath for 1 min at each setting. During low- and high-V(T) ventilation, the F(IO2) was highest at a flow of 5 L/min with a pharyngeal cannula. Oxygen delivery was higher with the pharyngeal cannula compared with the nasal cannula at all settings. Differences in flow did not result in significant differences in the F(IO2) with high- and low-V(T) ventilation. At a flow of 5 L/min via a pharyngeal cannula, open-mouth breathing resulted in a significantly higher F(IO2) compared with closed-mouth breathing. A pharyngeal cannula provided a higher F(IO2) compared with a nasal cannula at the same oxygen flow. Open-mouth breathing resulted in a higher F(IO2) compared with closed-mouth breathing when 5 L/min oxygen was delivered via a pharyngeal cannula. The breathing pattern did not affect the F(IO2) in this study. Copyright © 2015 by Daedalus Enterprises.

    Discrepancies in the management of pharyngitis in children have been reported in Europe and the United States, and recommendations concerning the use of clinical scores, rapid antigen diagnostic tests (RADTs) or throat cultures, and the indications for antibiotic treatment largely differ. This article summarizes the Italian guidelines on the management of pharyngitis in children issued by the National Institute of Health. A multidisciplinary panel of experts (the Guidelines Development Group) developed and used a set of key questions to conduct a systematic review of the literature. Relevant publications in English were identified through a systematic review of MEDLINE and the Cochrane Database of Systematic Reviews from their inception through April 30, 2011. Final recommendations were scaled according to the Italian National Guidelines Program grading. Eighteen clinical questions were defined, and 44 recommendations were issued. None of the available scoring systems is sufficiently accurate to identify group A β-hemolytic streptococci (GABHS) pharyngitis in settings with low prevalence for rheumatic disease. RADT should be performed by trained personnel in every child with a history and signs/symptoms suggestive of GABHS pharyngitis. RADT is not recommended in children with a McIsaac score of 0 or 1 with ≥2 signs/symptoms suggestive of viral infection. Backup culture in children with negative RADT result is not recommended. Culture test with antibiotic susceptibility assay should be performed exclusively for epidemiologic purposes. Streptococcal antibody titers are of no value in diagnosing acute pharyngitis. Antibiotic therapy is recommended in microbiologically documented GABHS pharyngitis. Because penicillin V is not available in Italy, amoxicillin (50 mg/kg/d in 2-3 doses orally) for 10 days is the first choice of treatment. In noncompliant cases, benzathine penicillin may be administered. Although not routinely recommended due to the high cost and wide

    Five of 34 patients (ages 4-21 years), who were subsequently diagnosed histologically as having fibrous dysplasia of the maxillary sinus, rapidly developed soft tissue masses of the malar region over a period of less than 4 months with accompanying pain (2 patients) and nasal obstruction and exophthalmos (2 patients). Each was clinically suspected of having a sarcoma. After resection, all lesions developed regrowth. At histopathologic examination, both initial and recurrent masses proved to be typical fibrous dysplasia. (orig./UWA)

    Full Text Available Objectives: The objective of this study was to assess the clinical characteristics, patterns, and factors associated with headache in patients with cerebral venous sinus thrombosis (CVT. Methods: In this prospective cohort study, we recruited conscious CVT patients who were able to give reliable history after consent. Institutional ethics approval was obtained. The diagnosis of CVT was based on the clinical and imaging parameters. Data regarding headache characteristic, severity (visual analog scale [VAS], imaging findings and outcome was recorded. Results: Forty-seven patients (19 males and 28 females with mean age 29.7 ± 8.7 years were recruited. The mean duration of headache was 12.6 ± 26.8 days, and VAS was 79.38 ± 13.41. Headache onset was acute in 51.1%, subacute in 42.6%, thunderclap in 4.3%, and chronic in 2.1%; location was holocranial in 36.2%, frontal in 27.7% patients; description was throbbing in 44.7% and aching in 25.5% patients. Superior sagittal sinus and transverse sinus were involved in 63.8% cases each. The prothrombotic factors were anemia in 55.3%, puerperal in 38.3%, hyperhomocysteinemia in 29.8%, and polycythemia in 19.1%. Conclusion: Holocranial and bifrontal headache of increasing severity may be a marker of CVT. This may be useful in clinical judgment in identifying conscious patients with CVT.

A complete surgical resection was carried out. The histopathological examination revealed deposits of dark-brownish pigments lining the submucosal tissue with adjacent lymphocytic inflammatory infiltrate and multinucleated giant cells phagocyting pigments. There was a negative staining for both iron and melanin. One year after lesion removal, the patient reported that the sinusitis crises had ceased after repeated episodes for years. It may be speculated that the inflammatory process related to amalgam tattoo seems to lead to a local immune response that causes sinusitis because it enhances the human leukocyte antigen DR (HLA-DR tissue expression.

  18. Early events in the pathogenesis of foot-and-mouth disease in pigs; identification of oropharyngeal tonsils as sites of primary and sustained viral replication.

    Directory of Open Access Journals (Sweden)

    Carolina Stenfeldt

    Full Text Available A time-course study was performed to elucidate the early events of foot-and-mouth disease virus (FMDV infection in pigs subsequent to simulated natural, intra-oropharyngeal, inoculation. The earliest detectable event was primary infection in the lingual and paraepiglottic tonsils at 6 hours post inoculation (hpi characterized by regional localization of viral RNA, viral antigen, and infectious virus. At this time FMDV antigen was localized in cytokeratin-positive epithelial cells and CD172a-expressing leukocytes of the crypt epithelium of the paraepiglottic tonsils. De novo replication of FMDV was first detected in oropharyngeal swab samples at 12 hpi and viremia occurred at 18-24 hpi, approximately 24 hours prior to the appearance of vesicular lesions. From 12 through 78 hpi, microscopic detection of FMDV was consistently localized to cytokeratin-positive cells within morphologically characteristic segments of oropharyngeal tonsil crypt epithelium. During this period, leukocyte populations expressing CD172a, SLA-DQ class II and/or CD8 were found in close proximity to infected epithelial cells, but with little or no co-localization with viral proteins. Similarly, M-cells expressing cytokeratin-18 did not co-localize with FMDV proteins. Intra-epithelial micro-vesicles composed of acantholytic epithelial cells expressing large amounts of structural and non-structural FMDV proteins were present within crypts of the tonsil of the soft palate during peak clinical infection. These findings inculpate the paraepiglottic tonsils as the primary site of FMDV infection in pigs exposed via the gastrointestinal tract. Furthermore, the continuing replication of FMDV in the oropharyngeal tonsils during viremia and peak clinical infection with no concurrent amplification of virus occurring in the lower respiratory tract indicates that these sites are the major source of shedding of FMDV from pigs.

    This cross-sectional study investigates the abundance of cefotaxime-resistant Escherichia coli (CREC) in the faeces and tonsils of 96 pigs during slaughter. Moreover, different isolates from a selected number of pigs were tested to study the diversity of bla ESBL genes within E. coli isolates from one pig. Cefotaxime-resistant bacteria (based on enumeration results on MacConkey agar supplemented with 1mg/L cefotaxime) were found in the faeces of 77 pigs (80%; 95% CI: 70-87%) and the tonsils of 91 pigs (95%; 95% CI: 88%-98%). Cefotaxime-resistant E. coli (based on enumeration results on Tryptone Bile X-glucuronide agar supplemented with 1mg/L cefotaxime) were detected in 72 faecal samples (75%; 95% CI: 64-83%) and 45 tonsil samples (47%; 95% CI: 35-59%), in numbers up to 5.5 and 5.6log 10 CFU/g, respectively. On average, around 1/10,000 E. coli in both faeces and tonsils were cefotaxime-resistant, though large variations were observed between pigs. Within one sample, CREC isolates with up to five different combinations of ESBL genes were observed. In three out of 16 faecal samples and six out of 14 tonsil samples, only one ESBL gene profile was found. The high numbers of CREC that are occasionally found in the faeces and tonsils of pigs during slaughter may represent an important source of contamination of carcasses and subsequently pork.

    Acute tonsillitis is the leading diagnosis in pediatric ambulatory care, and group A beta-hemolytic streptococcus is the main reason for antibiotic prescriptions in patients with acute tonsillitis. The aim of this study was to analyze trends in prescribing antibiotics and to investigate the prescription patterns for acute tonsillitis in pediatric ambulatory care in Taiwan from 2000 to 2009. Data on children younger than 18 years with a primary diagnosis of acute tonsillitis were retrieved from the National Health Insurance Research Database of Taiwan from 2000 to 2009. Concomitant bacterial infections were excluded. Sex, age, seasonality, location, level of medical institution, and physician specialty were analyzed. Annual and monthly changes in antibiotic prescriptions and classification were also evaluated. A total of 40,775 cases were enrolled, with an overall antibiotic prescription rate of 16.8%. There was a remarkable decline in the antibiotic prescription rates for tonsillitis from 28.4% in 2000 to 10.9% in 2009. Factors associated with a higher prescription rate included older age, visits from eastern Taiwan, medical centers, and nonpediatrician physicians. Otolaryngologists had higher antibiotic prescription rate, whereas pediatricians had the lowest (21.9% vs. 11.6%). The rates of obtaining throat cultures were low although the culture performing rate in the medical centers was significantly higher (12.3%, p < 0.001). From 2000 to 2009, there was a remarkable decline in the antibiotic prescription rates for tonsillitis. Further studies to evaluate diagnostic tools such as rapid antigen detection tests or throat cultures to decrease antibiotic prescriptions are warranted. Copyright © 2015. Published by Elsevier B.V.

    In Taiwan, a distinct ethnic group variation in incidence and mortality rates has been suggested for most carcinomas. Our aim is to identify the role of prognostic factors associated with the survival of oral and pharyngeal carcinoma in Taiwan. Taiwan Cancer Registry records of 9039 subjects diagnosed with oral and pharyngeal carcinoma were analyzed. The population was divided into three ethnic groups by residence, which were Taiwanese aborigines, Hakka and Hokkien communities. Five-year survival rates were estimated by Kaplan-Meier methods. Ethnic curves differed significantly by log-rank test; therefore separate models for Taiwanese aborigines, Hakka and Hokkien were carried out. The Cox multivariate proportional hazards model was used to examine the role of prognostic factors on ethnic survival. The five-year survival rates of oral and pharyngeal carcinoma were significantly poorer for Hokkien community (53.9%) and Taiwanese aborigines community (58.1%) compared with Hakka community (60.5%). The adjusted hazard ratio of Taiwanese aborigines versus Hakka was 1.07 (95%CI, 0.86–1.33) for oral and pharyngeal carcinoma mortality, and 1.16 (95%CI, 1.01–1.33) for Hokkien versus Hakka. Males had significantly poor prognosis than females. Subjects with tongue and/or mouth carcinoma presented the worst prognosis, whereas lip carcinoma had the best prognosis. Subjects with verrucous carcinoma had better survival than squamous cell carcinoma. Prognosis was the worst in elderly subjects, and subjects who underwent surgery had the highest survival rate. Our study presented that predictive variables in oral and pharyngeal carcinoma survival have been: ethnic groups, period of diagnosis, gender, diagnostic age, anatomic site, morphologic type, and therapy

    Full Text Available BACKGROUND: Regulatory T cells (Treg cells, which are essential for regulation of immune response to respiratory syncytial virus (RSV infection, are promoted by pharyngeal commensal pneumococcus. The effects of pharyngeal microflora disruption by antibiotics on airway responsiveness and relative immune responses after RSV infection have not been clarified. METHODS: Female BALB/c mice (aged 3 weeks were infected with RSV and then treated with either oral antibiotics or oral double distilled water (ddH(2O from 1 d post infection (pi. Changes in pharyngeal microflora were analyzed after antibiotic treatment for 7 d and 14 d. At 8 d pi and 15 d pi, the inflammatory cells in bronchoalveolar lavage fluid (BALF were investigated in combination with tests of pulmonary histopathology, airway hyperresponsiveness (AHR, pulmonary and splenic Treg cells responses. Pulmonary Foxp3 mRNA expression, IL-10 and TGF-β1 in BALF and lung homogenate were investigated at 15 d pi. Ovalbumin (OVA challenge was used to induce AHR after RSV infection. RESULTS: The predominant pharyngeal commensal, Streptococcus, was cleared by antibiotic treatment for 7 d. Same change also existed after antibiotic treatment for 14 d. After RSV infection, AHR was promoted by antibiotic treatment at 15 d pi. Synchronous decreases of pulmonary Treg cells, Foxp3 mRNA and TGF-β1 were detected. Similar results were observed under OVA challenge. CONCLUSIONS: After RSV infection, antibiotic treatment cleared pharyngeal commensal bacteria such as Streptococcus, which consequently, might induce AHR and decrease pulmonary Treg cells.

    Full Text Available Annually in Russia primary diagnosis of new-onset pharyngeal cancer is made in approximately 6–7 thousand people. To modern methods of diagnosing pharyngeal cancer belong: direct and indirect laryngoscopy, microlaryngoscopy, stroboscopy, fibrolaryngoscopy, X-ray study examination, computed tomography, multispiral computed tomography, magnetic resonance tomography, ultrasonographic examination of the throat and organs of the neck, acoustic analysis of voice and morphological studies.Recent years witnessed the development of novel methods of both conservative and surgical management of patient with pharyngeal cancer. Treatment of patients with stage T1–2 and in some patients with stage T3 includes the following methods: radiotherapy, chemoradiotherapy, endolaryngeal surgery with laser, photodynamic therapy, open functionally sparing operations. According to the data of the authors, today currently there is no common algorithm for treatment of stage T1–3 pharyngeal malignant neoplasms.Locally disseminated tumors of the throat and laryngopharynx, corresponding to stages T3–4N0–2M0 as a rule are treated by combined management with pre- or postoperative irradiation. Such approach results in leads to impairment of all functions of the organ and invalidity disablement of patients. The most important task after combined treatment is rehabilitation of the voice function, which may be restored by means of logopedic methods, voice-forming devices and reconstructive plastic operations.Hence novel approaches to treatment of pharyngeal cancer – both conservative and surgical have recently been worked out. However the problem concerning regarding therapeutic decision-making followed by rehabilitation of patients remains disputable.

    Coffee is one of the most popular and consumable drinks worldwide. However, there are conflicting results on the influence of this drink in oral and pharyngeal cancer risk. To clarify this, we aimed to systemically review and carry out a meta-analysis of the relevant literature on the association between coffee and oral and pharyngeal cancer. We carried out an electronic search of publications up to August 2016 from PubMed, National Library of Medicines Medline, Embase, Science Direct and the Cochrane Central Register. The Newcastle-Ottawa scale was used to address the quality of the studies a meta-analysis was carried out using random-effects models. From the 22,515 entries identified in the search, 13 case-control and 4 cohort studies were selected. With regards to quality on the Newcastle-Ottawa scale, an overall value of 6.06 was obtained. The analysis for oral and pharyngeal cancer grouped together indicated a pooled OR of .69 (95% CI of .57-.84; pcancers we observed a pooled OR of 0.82; 95% CI =.58-1.16; p=.257) and for pharyngeal cancers a pooled OR of .72 (95% CI of 0.54-.95; p=.019). There was no significant publication bias. The results show an inverse association between high coffee consumption and the risk of oral and pharyngeal cancers, which indicates that coffee may have a protective role against these cancers. Further larger prospective observational cohort studies are needed to address any effect of other possible co-factors.

    Full Text Available Mucoceles of the paranasal sinuses are slowly growing, epithelium-lined cystic lesions with sterile content. When the mucocele content becomes infected with a bacterial super-infection, the lesion is defined as mucopyocele. Mucoceles or mucopyoceles are commonly located in the frontal and anterior ethmoidal sinuses and can manifest with ocular signs and symptoms, mostly proptosis. In this report, we demonstrate a case of bilateral ethmoidal mucopyocele in a 53-year-old female who presented with reduced vision, diplopia, and proptosis. Computed tomography (CT scanning of the paranasal sinuses revealed cystic lesions filling the maxillary sinuses and anterior ethmoidal cells bilaterally and causing erosion in the walls of the sinuses. After marsupialization of the mucopyoceles was performed by endoscopic sinus surgery, the symptoms of the patient recovered rapidly. (Turk J Ophthalmol 2011; 41: 354-6

    Full Text Available Introduction: The sphenoid sinus is often neglected because of its difficult access. The deep position of the sphenoid sinus hinders early diagnosis of pathologies in that location. Delayed diagnosis can cause serious complications due to proximity to many important structures. Objectives: The aim of this study is to demonstrate different pathologies which can affect the sphenoid sinus and elucidate the findings. Methods: Cases of isolated sphenoid sinus lesions encountered in the neurosurgical setting which had rare pathologies are discussed. Pathologies such as Langerhans cell histiocytosis, solitary plasmacytoma, chordoma, pituitary adenoma, leiomyosarcoma, fungal infection, and mucocele which appeared primarily in sphenoid sinus are discussed along with their imaging features and pathological findings. Conclusion: Multitude of different pathologies can occur in sphenoid sinus. Detailed preoperative imaging is very helpful, but transnasal biopsy and histological study are required often for definitive diagnosis. The possible advantages of early diagnosis before spread of pathology for prognosis cannot be overemphasized.

    The frontal sinuses are pneumatic cavities located in the thickness of the squama frontalis, which communicate with the nasal cavity through the frontonasal duct. These cavities develop by the pneumatisation extent of some anterior ethmoidal cells. Morphologically, there is a large variability of the frontal sinus shape, size and extent, the position of the intersinusal septum, the existence and number of intrasinusal septa. There exist morphologically atypical frontal sinuses as: uni- or bilateral frontal sinuses aplasia, supernumerary sinuses, great extent of the cavities. Paranasal sinuses can be explored by different methods, but the most accessible and easy to perform is conventional radiological imaging. The radiographs can be morphometrically assessed in order to prove the individuality of these air cavities.

    Full Text Available Introduction: Fungal sinusitis is a well known disease in immunocompromised patients, but recently many reports have indicated an increased prevalence of fungal sinusitis in otherwise healthy individuals. The aim of this study was to assess the frequency of invasive fungal sinusitis (IFS in neutropenic patients and to determine outcome factors that may affect their survival. Methods: A total of 142 patients who were undergoing chemotherapy were followed by clinical and radiological features suggestive of fungal sinusitis. Patients with fever, headache, facial swelling and radiological finding underwent endoscopic sinus surgery. The biopsy materials were studied by mycological and histopathological methods. Results: Eleven from 142 patients were identified to have IFS. The ethiologic agents were Aspergillus flavus (5 cases, Alternaria sp. (3 cases, Aspergillus fumigatus (2 cases and mucor (1 case. Eight of 11 cases died. Conclusions: Invasive fungal sinusitis causes a high rate of mortality among immunocompromised patients. Therefore, early diagnosis with aggressive medical and surgical intervention is critical for survival.

    Full Text Available Purpose: We reported on the clinical approaches of ophthalmology and otorhinolaryngology departments in the treatment of the orbital complications of sinusitis. We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female. Thirty-two (62.7% were diagnosed with preseptal cellulitis and 19 (37.3% with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA, and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10 and statistically significant for preseptal and postseptal cellulitis groups (p<0.001. All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT scan can detect the extent of the infection. An initial trial of intravenosus (IV antibiotics may be appropriate when

    Long-term retrospective evaluation was performed of computed tomography (CT) images and endoscopic findings after endoscopic sinus surgery for 88 cases of chronic pediatric sinusitis with nasal polyps. The objective was to determine the appropriate duration of such postoperative evaluation for children. Fifty-one patients had both sinusitis and nasal polyps (BSP group), and the surgical procedure was decided in consideration of each patient's age (for less than 10 years of age, polypectomy (n=12); for 10-13 years old, anterior ethmoidectomy plus opening of the fontanelle and nasofrontal duct (n=20); and for serious cases older than 13 years, total sinusectomy (n=19)). On the other hand, for cases of unilateral sinusitis with antrochoanal polyps (USP group), anterior ethmoidectomy plus opening of the fontanelle was performed regardless of the patient's age (n=37, 5-15 years old). The postoperative endoscopic findings indicated that the polyps had been eliminated in approximately 91% of total patients. Good postoperative findings of CT images in most patients of USP group are observed at one year after the operation like the same of the postoperative course of adult chronic sinusitis. On the other hand CT images in BSP group evaluated one year after the operation were rated as unchanged or worsened in approximately half of the patients. However, at 4 years after the operation nearly all the patients were rated as improved or better. In addition, comparison of the age at final observation and the postoperative course found a striking decrease in the proportion of unchanged and worsened patients aged 12 and above. Accordingly, it was concluded that there is difference of healing process after the operation between USP and BSP group. Postoperative evaluation of BSP group should be performed for 4 years and up to an age of at least 12 years although post-ESS following of USP group is similar to that of adult sinusitis.

    The purpose of this study was to clarify the relationships between upper airway factors (nasal resistance, adenoids, tonsils, and tongue posture) and maxillofacial forms in Class II and III children. Sixty-four subjects (mean age, 9.3 years) with malocclusion were divided into Class II and Class III groups by ANB angles. Nasal resistance was calculated using computational fluid dynamics from cone-beam computed tomography data. Adenoids, tonsils, and tongue posture were evaluated in the cone-beam computed tomography images. The groups were compared using Mann-Whitney U tests and Student t tests. The Spearman rank correlations test assessed the relationships between the upper airway factors and maxillofacial form. Nasal resistance of the Class II group was significantly larger than that of the Class III group (P = 0.005). Nasal resistance of the Class II group was significantly correlated with inferior tongue posture (P Class III group was significantly correlated with anterior tongue posture (P Class III group was significantly correlated with mandibular protrusion. The relationships of upper airway factors differ between Class II and Class III children. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

    Pott's puffy tumor is an extremely rare and potentially life-threatening complication of frontal sinusitis. We report a case of a 64-year-old man who presented at our emergency department with mild tenderness on the glabellar area and diplopia. Computed Tomography (CT) revealed frontal sinusitis and osteomyelitis of the frontal bone. Following sinus trephination and long-term antibiotic therapy, the patient achieved a complete recovery.

    Nasal congestion is a common problem for many people. It is a symptom of chronic sinusitis and also a characteristic of allergic rhinitis. Individuals frequently confuse sinusitis and allergic rhinitis. The expert system described below will diagnose the problem to be either rhinitis or sinusitis. In this paper we describe the expert system, the need for such an expert system and the process of developing the system.

    A rare case of straight sinus thrombosis in a 36-year-old female with sudden onset of status migrainosus is presented. This condition was demonstrated by a linear density in the midline on a noncontrast computed tomography scan, as a filling defect at the location of straight sinus on magnetic resonance imaging, and by the inability to visualize blood flow in the straight sinus on magnetic resonance venography, with a similar demonstration on a 4-vessel digital subtraction angiography.

    The CT scores and scoring for improvement based on them, which we proposed previously, is a simple and highly reproducible method of evaluation of sinus units before and after an operation for chronic sinusitis. We compared this evaluation method with the results of quantitative assay and showed its advantages and disadvantages. The subjects were 258 sinuses in patients who underwent endonasal sinus surgery (ESS) in the department of otolaryngology, Kyoto Prefectural University of Medicine Hospital from April 1996 to April 1997. The subjects were evaluated according to the following 4 grades negligible shadow in the paranasal sinus CT scored 0, less than 50% shadow scored 1, more than 50% of shadow scored 2, and mostly filled with shadow scored 3. Furthermore, the preoperative and postoperative CT scores were compared and the rate of improvement was rated in the following 3 grades: score 0 for unchanged or aggravated subjects, score 1 for subjects showing improved CT score by 1 grade, and score 2 for those showing improved CT score by 2 grades or a postoperative CT score of 0. Quantitative image analysis was input into a personal computer and the ratio occupied by the shadow was calculated, as the shadow ratio. While some discrepancies were seen in parts in the comparison of the quantitative image analysis and CT scores as the former captures minute shadows, a positive correlation was obtained overall. Attention is needed to accurately evaluate small paranasal sinuses such as the frontal sinus, and small amounts of shadow, which are areas where errors may occur. A satisfactory correlation was obtained between the score for the improvement rate and the difference in the shadow ratios before and after surgery. The CT scores and the scores for the improvement rate showed no difference from the results of other evaluation methods reported in the past, and evaluation of similar precision was possible. It was thought that this simple evaluation method of CT findings in

    Fibrous dysplasia is an uncommon benign disease of the bone, with slow progression. Monostotic involvement of the paranasal sinuses is rare. We report a 54-year-old woman who had complaints of facial asymmetry, chronic sinusitis, recurrent headaches, and nasal obstruction for two years. Conventional radiography showed opacification and expansion of the maxillary sinus. Axial and coronal computed tomography scans showed a heterogeneous mass that expanded the right maxillary sinus, leading to nasal obstruction and cortical thickening of the maxilla. No signs of destruction or erosion in the cortical bone were identified. An endonasal endoscopic biopsy was performed and the diagnosis of fibrous dysplasia was confirmed histologically.

    We conducted prospective study comparing different methods (plain X-rays, computed tomography and ultrasonography mode-A) for the initial diagnosis of maxillary sinusitis. Twenty patients (40 maxillary sinuses) with a clinical history suggestive of sinusitis included in this study. The results were classified as abnormal or normal, using computed tomography as gold standard. The sensitivity for ultrasonography and plain X-rays was 84.6% and 69.2%, respectively. The specificity of both methods was 92.6%. This study suggests that ultrasonography can be used as a good follow-up method for patients with maxillary. sinusitis. (author)

    Trichomonal disease typically involves the genital and occasionally respiratory tracts. Although exposure of the upper respiratory tract to infected genital secretions is not uncommon with contemporary sexual practices, trichomonal sinus disease has been rarely described. The present report describes the case of a healthy 17-year-old male admitted to an intensive care unit following multiple trauma, who developed purulent sinusitis on the 4th day of hospitalization. Numerous trichomonads were noted on microscopic examination of sinus aspirate. Further investigation revealed orofacial sexual exposure of the patient to a partner with trichomoniasis. The patient's sinusitis resolved following a course of parenteral metronidazole-containing antibiotics.

    Full Text Available Inflammatory diseases of the paranasal sinuses (SNPs are one of the most urgent problems of otorhinolaryngology. The number of patients with inflammatory diseases of the UNP remains high in our country and abroad, despite the development and introduction of new advanced methods of treatment. From 15to 36% of patients with sinusitis are treated in the ENT departments. Over the last two decades the SNPs diseases increased more than 10 times in Russia. Therefore the diagnosis and treatment of sinusitis is an actual problem of modern otorhinolaryngology. It is necessary to develop effective, reliable and non-invasive diagnostic methods of sinusitis.

  1. Adaptive phenotypic plasticity in the Midas cichlid fish pharyngeal jaw and its relevance in adaptive radiation

    Full Text Available Abstract Background Phenotypic evolution and its role in the diversification of organisms is a central topic in evolutionary biology. A neglected factor during the modern evolutionary synthesis, adaptive phenotypic plasticity, more recently attracted the attention of many evolutionary biologists and is now recognized as an important ingredient in both population persistence and diversification. The traits and directions in which an ancestral source population displays phenotypic plasticity might partly determine the trajectories in morphospace, which are accessible for an adaptive radiation, starting from the colonization of a novel environment. In the case of repeated colonizations of similar environments from the same source population this "flexible stem" hypothesis predicts similar phenotypes to arise in repeated subsequent radiations. The Midas Cichlid (Amphilophus spp. in Nicaragua has radiated in parallel in several crater-lakes seeded by populations originating from the Nicaraguan Great Lakes. Here, we tested phenotypic plasticity in the pharyngeal jaw of Midas Cichlids. The pharyngeal jaw apparatus of cichlids, a second set of jaws functionally decoupled from the oral ones, is known to mediate ecological specialization and often differs strongly between sister-species. Results We performed a common garden experiment raising three groups of Midas cichlids on food differing in hardness and calcium content. Analyzing the lower pharyngeal jaw-bones we find significant differences between diet groups qualitatively resembling the differences found between specialized species. Observed differences in pharyngeal jaw expression between groups were attributable to the diet's mechanical resistance, whereas surplus calcium in the diet was not found to be of importance. Conclusions The pharyngeal jaw apparatus of Midas Cichlids can be expressed plastically if stimulated mechanically during feeding. Since this trait is commonly differentiated - among

    Full Text Available Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality. Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity. Results: Among our cases, 111 (43.5% were male and 145 (56.5% were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%, 55.5% of which were male and 44.5% were female (P=0.001. Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1%; P<0.01. Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed

    The detection of lesions of the paranasal sinuses as incidental findings during magnetic resonance imaging of patients suspected of intracranial disease who have no nasal symptoms has been far more common than we expected. The present study was performed on 325 patients with a mean age of 60.7 years. Medical histories were taken whether they had any nasal symptoms or not. Asymptomatic sinus disease was present in 41.6% of the 257 patients who had no nasal symptoms, and 9.7% of the patients had either marked mucosal thickening, excessive fluid or polyps in the maxillary sinuses. Although the mean age of these patients was comparatively high, we can infer that 1 in 10 have relatively severe sinus lesions. Mucociliary transport time was measured using the saccharin method in 15 patients who had sinus disease but no nasal symptoms. The mean transport time was 15.6 minutes and within normal limits. Routine ENT examination revealed no lesions in the nasal cavity of any of the subjects. We classified the patients with asymptomatic sinus disease into two groups -- group A: patients with sinus disease associated with some nasal manifestations but who did not complain about them, and group B: patients who had sinus disease but did not have any nasal problems. Group B represents genuine asymptomatic sinus disease in the narrow sense. Most asymptomatic patients in this study appeared to belong to group B. They had some sinus disease, but because their mucociliary function in their nasal cavity was normal, they did not have any nasal symptoms. When we find patients with asymptomatic sinus disease, we have to determine which group they belong to by examining their nasal cavity and measuring their saccharin time. Patients in group A should be medically treated, but those in group B should be followed without medical treatment. (author)

    A slow-growing frontal sinus osteoma has been followed up since the year 2001 by clinical, endoscopic, and radiological examination in the Department of Otolaryngology, New Medical Centre Specialty Hospital, Abu Dhabi, for 10 years until the year 2010. The last computed tomography scan of paranasal sinuses was done on April 5, 2010, which revealed increasing size of the osteoma by 38.1 mm; and it has become symptomatic. No specific cause of the sudden change of growth of the osteoma could be evaluated from the history and clinical examination. There was an increase in the frequency of headache and feeling of pressure in the forehead. Choice of surgical approach was difficult in this popular era of endonasal endoscopic sinus approach. A great deal of effort was made after reviewing the literature and consultation with the radiologist and neurosurgeon to accept the bicoronal osteoplastic flap approach. A broad-based posterior frontal sinus is found to be ideal for external approach. Copyright © 2011 Elsevier Inc. All rights reserved.

    The anatomic distribution of smooth muscle myosin, a contractile protein, was determined in a variety of lymphoid tissues (spleen, lymph nodes, tonsils) with the use of highly specific rabbit antibodies to human uterine smooth muscle myosin and an indirect immunoperoxidase technique. In the spleen, in addition to the anticipated immunoreactivity in the walls of arteries, veins, splenic capsule, and trabeculas, other staining patterns were observed. Smooth muscle myosin-containing cells which comprised the adventitia of the trabecular arteries appeared continuous with myosin-containing reticular cells of the white pulp. The latter cells assumed a circumferential pattern within the periarteriolar lymphoid sheaths, then blended delicately with the red pulp at the marginal zone. Ultrastructurally, immunogold techniques demonstrated that smooth muscle myosin in these cells was localized to cytoplasmic filaments. Within the red pulp, a different and distinct staining pattern was observed for the splenic sinuses. Short, regular, orderly, and repetitive bands of immunoreactivity, aligned parallel to the long axis of the sinus, extended between contiguous ring fibers. By immunoelectron microscopy these structures corresponded to distinct bundles of filaments in the endothelial lining cells of the splenic sinuses. Factor VIII associated antigen was also identified in the splenic lining cells in cryostat and paraffin sections, and ultrastructurally. Within the red pulp of the spleen, the sheaths of sheathed capillaries also revealed strong immunoreactivity for smooth muscle myosin. Other sites of immunohistochemical localization of smooth muscle myosin included dendritic reticulum cells present in reactive follicles and in nodular non-Hodgkin's lymphomas. Certain vascular structures, specifically sinus lining cells and Schweigger-Seidel capillary sheaths of the spleen and postcapillary venules of lymph nodes and tonsils, coexpressed smooth muscle myosin and Factor VIII

    Intrasinus new bone formation (BF) has been observed after no-grafting osteotome sinus augmentation, and it is hypothesized to be influenced by the dimensions of the maxillary sinus. The aim of this clinical trial is to evaluate the influence of lateral-medial sinus width (SW) on no-grafting osteotome sinus augmentation outcomes using cone-beam computed tomography. All patients recruited for this prospective study were treated with no-grafting osteotome sinus augmentation with simultaneous implant placement. Cone-beam computed tomography was obtained before, immediately after, and 6 months after the surgical procedure to use for measurements. Descriptive statistics were calculated and univariate, bivariate, and multivariate analysis were conducted to evaluate the influence of average SW and other relevant factors on procedure outcomes, including new BF, residual bone resorption (BR), and change of peri-implant bone height (CPBH). A total of 48 implants placed in 32 elevated sinuses of 29 patients were included. The average SW was 11.3 ± 1.8 mm. Intrasinus BF measured 1.7 ± 0.9 mm at 6 months after surgery. The amount of BR was 0.3 ± 0.9 mm, and CPBH was calculated as 1.3 ± 1.3 mm. Multivariate analysis showed a negative correlation between SW and BF (r = -0.469, P = .001), as well as between SW and CPBH (r = -0.562, P = .001). A positive correlation was discovered between SW and BR (r = 0.311, P = .027) in general. The lateral-medial SW was observed to have a negative correlation with new BF and CPBH after no-grafting osteotome sinus augmentation.

    2015-01-01

    Fibrous dysplasia is a benign fibro-osseous lesion progressing with one or more bone involvements in the skeleton. Even though it is a benign tumor, it may potentially transform into a malignant one. While the most frequently involved zones in the head-neck zone include the maxilla, mandible, parietal, occipital, and temporal zones, the involvement of the ethmoid bone is rather rare. This article presents the case of a female patient who was diagnosed with fibrous dysplasia in the right ethmoid sinus based on the paranasal computerized tomography scan that was taken due to the symptoms of pain around the right eye, pressure, and a feeling of being pushed.

    Radiography and endoscopy of a 17-day-old Standardbred foal that had right-sided facial swelling and dyspnea since birth revealed a soft tissue mass in the right nasal passage and right maxillary and frontal sinuses. A bone flap was used to expose the mass, and a fluid-filled structure was removed surgically. After surgery, the dyspnea was alleviated. The facial deformity resolved by the time the foal was 6 months old. The upper airway obstruction was absent clinically and endoscopically by the time the foal was 17 months old

    Full Text Available Diseases of the tonsils are becoming more resistant to antibiotics due to the persistence of bacteria through the formation of biofilms. Therefore, understanding the microbiology and pathophysiology of such diseases represent an important step in the management of biofilm-related infections. We have isolated the microorganisms, evaluated their antimicrobial susceptibility, and detected the presence of bacterial biofilms in tonsillar specimens in correlation with the clinical manifestations of tonsillar diseases. Therefore, a total of 140 palatine tonsils were collected from 70 patients undergoing tonsillectomy at University Malaya Medical Centre. The most recovered isolate was Staphylococcus aureus (39.65% followed by Haemophilus influenzae (18.53%. There was high susceptibility against all selected antibiotics except for cotrimoxazole. Bacterial biofilms were detected in 60% of patients and a significant percentage of patients demonstrated infection manifestation rather than obstruction. In addition, an association between clinical symptoms like snore, apnea, nasal obstruction, and tonsillar hypertrophy was found to be related to the microbiology of tonsils particularly to the presence of biofilms. In conclusion, evidence of biofilms in tonsils in correlation with the demonstrated clinical symptoms explains the recalcitrant nature of tonsillar diseases and highlights the importance of biofilm’s early detection and prevention towards better therapeutic management of biofilm-related infections.

  13. Dicer activity in neural crest cells is essential for craniofacial organogenesis and pharyngeal arch artery morphogenesis

    Nie, Xuguang; Wang, Qin; Jiao, Kai

    2014-01-01

    MicroRNAs (miRNAs) play important roles in regulating gene expression during numerous biological/pathological processes. Dicer encodes an RNase III endonuclease that is essential for generating most, if not all, functional miRNAs. In this work, we applied a conditional gene inactivation approach to examine the function of Dicer during neural crest cell (NCC) development. Mice with NCC-specific inactivation of Dicer died perinatally. Cranial and cardiac NCC migration into target tissues was not affected by Dicer disruption, but their subsequent development was disturbed. NCC derivatives and their associated mesoderm-derived cells displayed massive apoptosis, leading to severe abnormalities during craniofacial morphogenesis and organogenesis. In addition, the 4th pharyngeal arch artery (PAA) remodeling was affected, resulting in interrupted aortic arch artery type B (IAA-B) in mutant animals. Taken together, our results show that Dicer activity in NCCs is essential for craniofacial development and pharyngeal arch artery morphogenesis. PMID:21256960

    The technique was used in nondysphagic volunteers and in dysphagic patients. Our normal values in nondysphagic volunteers are in accordance with normal values in the literature. Regarding catheter movement we found the a previously not described sensor movement where the sensor in the upper esophageal sphincter followed the laryngeal elevation with no response to soft palate elevation. We found a longitudinal asymmetry in the pharynx with higher contraction pressures at lower levels. In the experimental model we found that intrabolus pressure was dependent on bolus volume, lumen narrowing, sensor position, flow rate, and bolus viscosity. In patients with a cricopharyngeal indentation we found weak pharyngeal constrictors with outpouching of the lumen above and below. Finally, in dysphagic patients with a normal radiologic investigation, videomanometry displayed abnormalities in 74% of the patients. We conclude that barium swallow and manometry are complementary and we suggest the addition of pharyngeal solid state manometry, preferably with simultaneous videoradiography, in dysphagic patients. 128 refs, 4 figs

    Sparc (Osteonectin), a matricellular glycoprotein expressed by many differentiated cells, is a major non-collagenous constituent of vertebrate bones. Recent studies indicate that Sparc expression appears early in development, although its function and regulation during embryogenesis are largely unknown. We cloned zebrafish sparc and investigated its role during development, using a mo rpholino antisense oligonucleotide-based knockdown approach. Consistent with its strong expression in the otic vesicle and developing pharyngeal cartilages, knockdown of Sparc function resulted in specific inner ear and cartilage defects that are highlighted by changes in gene expression, morphology and behavior. We rescued the knockdown phenotypes by co-injecting sparc mRNA, providing evidence that the knockdown phenotype is due specifically to impairment of Sparc function. A comparison of the phenotypes of Sparc knockdown and known zebrafish mutants with similar defects places Sparc downstream of sox9 in the genetic network that regulates development of the pharyngeal skeleton and inner ear of vertebrates.

    The aim of this clinical investigation was to evaluate the clinical and radiologic outcomes of a single-step surgical procedure that includes functional endoscopic sinus surgery (FESS) and maxillary sinus elevation by the lateral window approach in patients with reversible contraindications to sinus elevation. Thirty-eight patients with insufficient bone height in the posterior maxilla caused by pneumatization of the sinus and with reversible ear-nose-throat (ENT) contraindications to sinus elevation were recruited for this investigation between January 2010 and January 2012. All patients were treated in a single session under general anesthesia for a total of 69 consecutive sinus augmentations. FESS was performed by an ENT specialist, and an oral surgeon carried out sinus elevation through the lateral window approach. Particulate xenograft was used beneath the sinus membrane. Intraoperative and postoperative complications (eg, membrane tears, rhinosinusitis, graft infection or loss) were reported. Nasal endoscopies were performed at 7, 14, and 30 days and 3 months after treatment. After a healing period of 6 months, 137 implants were inserted. Computed tomography scans were performed after 6 months and 1 year. Intraoperative membrane perforation occurred in only one case. No implant failures were recorded during the follow-up period. Radiologic and clinical findings showed the resolution of ENT disease and good bone graft integration after 1 year. A relapse of mucosal thickening observed in some patients did not influence the graft healing. Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

  1. An unusual case of fibrous dysplasia of the maxillary sinus.

    Science.gov (United States)

    Crawford, Larry B

    2003-12-01

    Fibrous dysplasia of the maxillary sinus might initially become apparent because of facial asymmetry. It can be differentiated from other osseo-odontogenic dysplasias radiographically by its occupancy of the affected sinus and by its diffuse, ground-glass, radiopaque appearance; it can be further confirmed with histologic findings. It is normally self-limiting in growth and does not usually become malignant.

    2013-01-01

    Full Text Available Introduction. An antrolith is a calcified mass within the maxillary sinus. The origin of the nidus of calcification may be extrinsic (foreign body in sinus or intrinsic (stagnant mucus and fungal ball. Most antroliths are small and asymptomatic. Larger ones may present as sinusitis with symptoms like pain and discharge. Case Report. We report a case of a 47-year-old lady who presented with heaviness on the left side of the face and loosening of the left 2nd molar tooth since two months. CT scan of the osteomeatal complex and paranasal sinuses showed an opacification of bilateral maxillary sinus and an amorphous area of bone density in the left maxillary sinus. Because of the size of the mass, benign neoplasms were considered in the differential diagnosis. During an endoscopic sinus surgery, it was found to be an antrolith, which was successfully managed by antrostomy and Caldwell-Luc Surgery. Discussion. Antrolith is a rare condition. Rhinoliths are known to invade into the maxillary antrum, but a localised lesion in the antrum is very unusual. A case of an isolated antrolith is presented for its rarity and for differential diagnosis of localised antral disease. Conclusion. Antrolith should be considered as differential diagnosis of unilateral radio-opaque paranasal sinus lesions.

    In everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results. We couldn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate. CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis. (author)

    2015-10-01

    Full Text Available ABSTRACT INTRODUCTION: Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE: To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contamination of the sinus in patients who develop maxillary sinus infection. METHODS: Cross-sectional study in 60 palatal roots of the first maxillary molars near the maxillary sinus, that underwent endodontic treatment for apical periodontitis. After removal of the filling material, dentin shavings were collected and placed in test tubes containing Sabouraud dextrose agar and chloramphenicol. The phenotype was determined by macroscopic and microscopic examination of the colonies. For polymerase chain reaction, the primers ITS-5 and ITS-4 were used. The sequences obtained were compared with those deposited at GenBank using the Basic Local Alignment Search Tool program. RESULTS: Filamentous fungi were isolated from 6 of 60 canals (10%:Aspergillus niger (6.7%, Aspergillus versicolor (1.6%, and Aspergillus fumigatus(1.6%. CONCLUSION: Root canals near the maxillary sinus with endodontic treatment and apical periodontitis may exhibit positive cultures for filamentous fungi. Interested professionals should be alert, because these microorganisms have pathogenic characteristics that can cause disease of odontogenic origin in the maxillary sinus.

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean{+-}SD; 19.72{+-}0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study. (orig.)

  7. Effects of mandibular setback with or without maxillary advancement osteotomies on pharyngeal airways: An overview of systematic reviews.

    Directory of Open Access Journals (Sweden)

    Su Keng Tan

    Full Text Available Mandibular setback osteotomies potentially lead to narrowing of the pharyngeal airways, subsequently resulting in post-surgical obstructive sleep apnea (OSA.To summarize current evidence from systematic reviews that has evaluated pharyngeal airway changes after mandibular setback with or without concomitant upper jaw osteotomies.PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched with no restriction of language or date. Systematic reviews studying changes in pharyngeal airway dimensions and respiratory parameters after mandibular setback with or without concomitant upper jaw osteotomies have been identified, screened for eligibility, included and analyzed in this study.Six systematic reviews have been included. While isolated mandibular setback osteotomies result in reduced oropharyngeal airway dimensions, the reduction is lesser in cases with concomitant upper jaw osteotomies. Only scarce evidence exists currently to what happens to naso- and hypo-pharyngeal airways. There is no evidence for post-surgical OSA, even though some studies reported reduced respiratory parameters after single-jaw mandibular setback with or without concomitant upper jaw osteotomies.Although mandibular setback osteotomies reduce pharyngeal airway dimensions, evidence confirming post-surgical OSA was not found. Nevertheless, potential post-surgical OSA should be taken into serious consideration during the treatment planning of particular orthognathic cases. As moderate evidence exists that double-jaw surgeries lead to less compromised post-surgical pharyngeal airways, they should be considered as the method of choice especially in cases with severe dentoskeletal Class III deformity.PROSPERO (registration number: CRD42016046484.

    Consensus guidelines recommend against testing or treating adults at low risk for group A streptococcal (GAS) pharyngitis. To help patients decide when to visit a clinician for the evaluation of sore throat. Retrospective cohort study. A national chain of retail health clinics. 71 776 patients aged 15 years or older with pharyngitis who visited a clinic from September 2006 to December 2008. The authors created a score using information from patient-reported clinical variables plus the incidence of local disease and compared it with the Centor score and other traditional scores that require clinician-elicited signs. If patients aged 15 years or older with sore throat did not visit a clinician when the new score estimated the likelihood of GAS pharyngitis to be less than 10% instead of having clinicians manage their symptoms following guidelines that use the Centor score, 230 000 visits would be avoided in the United States each year and 8500 patients with GAS pharyngitis who would have received antibiotics would not be treated with them. Real-time information about the local incidence of GAS pharyngitis, which is necessary to calculate the new score, is not currently available. A patient-driven approach to pharyngitis diagnosis that uses this new score could save hundreds of thousands of visits annually by identifying patients at home who are unlikely to require testing or treatment.

    Cryptosporidium spp. infection was associated with aural-pharyngeal polyps in three iguanas (Iguana iguana). All iguanas were presented for masses protruding from the ear canal, and the disease was characterized by a chronic clinical course. The masses consisted of nests of cystic glands surrounded by abundant fibrous connective tissue and lined by hyperplastic cuboidal to pseudostratified columnar epithelium that was moderately to heavily colonized by cryptosporidial organisms. Electron microscopy revealed that the majority of organisms were trophozoites.

    Stimulation of the esophagus activates the pharyngeal swallow response (EPSR) in human infants and animals. The aims of this study were to characterize the stimulus and response of the EPSR and to determine the function and mechanisms generating the EPSR. Studies were conducted in 46 decerebrate cats in which pharyngeal, laryngeal, and esophageal motility was monitored using EMG, strain gauges, or manometry. The esophagus was stimulated by balloon distension or luminal fluid infusion. We found that esophageal distension increased the chance of occurrence of the EPSR, but the delay was variable. The chance of occurrence of the EPSR was related to the position, magnitude, and length of the stimulus in the esophagus. The most effective stimulus was long, strong, and situated in the cervical esophagus. Acidification of the esophagus activated pharyngeal swallows and sensitized the receptors that activate the EPSR. The EPSR was blocked by local anesthesia applied to the esophageal lumen, and electrical stimulation of the recurrent laryngeal nerve caudal to the cricoid cartilage (RLNc) activated the pharyngeal swallow response. We conclude that the EPSR is activated in a probabilistic manner. The receptors mediating the EPSR are probably mucosal slowly adapting tension receptors. The sensory neural pathway includes the RLNc and superior laryngeal nerve. We hypothesize that, because the EPSR is observed in human infants and animals, but not human adults, activation of EPSR is related to the elevated position of the larynx. In this situation, the EPSR occurs rather than secondary peristalsis to prevent supraesophageal reflux when the esophageal bolus is in the proximal esophagus.

    Full text: Children with cerebral palsy (CP) may have abnormal respiratory function because of aspiration pneumonitis, chest deformity, upper airways obstruction or central respiratory control abnormalities. The diagnosis of aspiration has long confounded clinicians and is often made indirectly after exclusion of other causes of respiratory disease in susceptible individuals. The radiosalivagram is a technique which permits the demonstration of aspiration of pharyngeal contents in individuals with pharyngeal incoordination. It is a simple procedure which provides both qualitative and quantitative evidence of aspiration. Over an hour and while supine, 20 mL of {sup 99m}Tc-sulphur colloid is instilled into the pharynx via a thin plastic tube using a syringe pump. The neck, thorax and upper abdomen are imaged continuously In normal individuals, radioactivity is demonstrated in the pharynx, oesophagus and stomach; in the presence of pharyngeal incoordination, radioactivity is seen within one or both main bronchi and adjacent lung fields. The rate of clearance from the lungs varies and can be quantified. We have studied 31 children with severe non-ambulant CR The time to first aspiration, maximum quantity aspirated, and retention of aspirated material at 2h have been determined. These data have been compared with measurements of respiratory function. Preliminary results of this ongoing study reveal a broad range of outcomes. Seventeen children (17/31) had aspiration, in 15/17 aspiration was unilateral and in 14/17 there was spontaneous early clearance. The investigation was well tolerated by patients. The radiosalivagram is a simple, quantifiable investigation for demonstrating or excluding pharyngeal incoordination and aspiration in children with unexplained respiratory disease.

    Conclusion: The result of the present study showed that penicillin and erythromycin are still the most effective antibiotics against the organism. The emm typing revealed that emm type-3 was detected in most of the isolates from patients with purulent pharyngitis. On the basis of the findings of this study, we may conclude that emm typing provides new insights on the genetic diversity of the M proteins, and is of demonstrable value for molecular studies of GAS.

    Artmann, A; Henninger, W

    2001-12-01

    Documentation of the psittacine paranasal sinuses has been limited. To provide more published detail, spiral computed tomography (CT) was used to scan the cephalic and cervical region from cadavers of 10 psittacine birds (Ara ararauna, Ara chloroptera, Ara macao, and Anodorhynchus hyacinthinus). Skeletal studies, histologic examinations, and evaluation of deep-frozen sections and anatomic preparations confirmed the results of the CT scans. New morphologic details of the paranasal sinus and some compartments were discovered. The paranasal sinuses of these macaws consist of two unpaired rostral compartments, followed caudally by eight paired compartments. Histologic examinations revealed that the walls of the paranasal sinuses consist of flat or cubic monolayer epithelium with underlying connective tissue. The described method of CT examination of these macaws, especially the positioning, scan orientation and parameters, and documentation of the normal paranasal sinus, provides a basis for future clinical use of CT.

    Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

To date, there has been no documented report of brain abscess as a complication of spinal dermal sinus. Here, we report an 8-month-old girl who was presented initially with a brain abscess at early infancy but lumbar dermal sinus and associated spinal abscess were discovered afterwards. The probable mechanisms of this rare association have been discussed.Keywords: brain abscess, spinal dermal sinus, spinal abscess

    We examined the effect of electrical stimulation of the hypoglossal nerve and pharyngeal lubrication with artificial surfactant (Surfactant T-A) on the opening of obstructed upper airway in nine anesthetized supine dogs. The upper airway was isolated from the lower airway by transecting the cervical trachea. Upper airway obstruction was induced by applying constant negative pressures (5, 10, 20, and 30 cmH2O) on the rostral cut end of the trachea. Peripheral cut ends of the hypoglossal nerves were electrically stimulated by square-wave pulses at various frequencies from 10 to 30 Hz (0.2-ms duration, 5-7 V), and the critical stimulating frequency necessary for opening the obstructed upper airway was measured at each driving pressure before and after pharyngeal lubrication with artificial surfactant. The critical stimulation frequency for upper airway opening significantly increased as upper airway pressure became more negative and significantly decreased with lubrication of the upper airway. These findings suggest that greater muscle tone of the genioglossus is needed to open the occluded upper airway with larger negative intraluminal pressure and that lubrication of the pharyngeal mucosa with artificial surfactant facilitates reopening of the upper airway.

    Historically at The Hospital for Sick Children in Toronto, pharyngeal flap pharyngoplasty has been the treatment of choice for treatment of velopharyngeal insufficiency, regardless of velopharyngeal closure pattern. The authors hypothesize that pharyngeal flap pharyngoplasty is more effective in treating velopharyngeal insufficiency in patients with circular or sagittal velopharyngeal closure and less effective in treating the coronal closure pattern. Ninety-three patients who underwent superiorly based pharyngeal flap surgery for velopharyngeal insufficiency were evaluated in a retrospective chart review. Closure pattern was determined preoperatively by nasopharyngoscopy or multiview videofluoroscopy. Nasalance was assessed preoperatively and at 6 weeks and 1 year postoperatively. Nasalance during nonnasal speech was decreased on average, for all closure patterns, postoperatively. However, a significantly higher percentage of patients were corrected to normal nasalance scores in thenoncoronal group than in the coronal group (57 percent versus 35 percent, respectively) at 1 year postoperatively (p approach to the management of velopharyngeal insufficiency and are more inclined to treat coronal pattern velopharyngeal insufficiency with sphincter pharyngoplasty.

    Full Text Available Background: The morphometry of the palate and pharyngeal airway has a crucial role in the development of disorders like apnea. Therefore the present study aims to explore the shape and dimensions of the palate and the pharyngeal airway. Materials and Methods: The study was carried out on normal sagittal and axial sections of head and neck in 100 CT images. Results: The average length of the hard and soft palates measured 4.49±0.38 and 3.44±0.61cm respectively. The anteroposterior dimension of the soft palate was 0.90±0.33 cm. The velopalatine angle measured 130.23±9.98º. The luminal areas were 4.59±1.81, 2.058±1.09 and 2.99±1.08 cm in naso, oro and laryngo pharynx respectively. The soft palate showed varied shapes which were classified as a straight line, leaf-like, rat-tail, distorted S, crooked and butt like. Conclusion: The present study attempts to provide a normal database to understand the anatomy of the soft palate and pharyngeal airways.
