    Full Text Available Background: Adenoid hypertrophy is one of the most common health problems affecting the paediatric population. This study aims to correlate adenoidal nasopharyngeal ratio (ANR with symptoms of enlarged adenoids in children with enlarged adenoids. Materials and Methods: It was a year, cross-sectional, hospital-based study conducted at Lautech Teaching Hospital, Osogbo. ANR was determined by dividing adenoidal depth with nasopharyngeal depth on the plain lateral radiographs. Results: A total of 90 consecutive children consisting of 61 males and 29 females were included in the study with M:F ratio of 2.1:1. Their ages ranged from 8 months to 11 years. All the patients presented with nasal obstruction, mouth breathing and noisy breathing. Majority (64.5% had severe obstructions with preponderance among children of 3-5 years (39.9%. Linear regression analysis showed significant association between age and ANR (t = 10.447, P < 0.001. There was high significant association (P < 0.05 between presenting symptoms and degree of nasopharyngeal airway obstruction; for snoring (r = 0.251, P = 0.000, sleep apnoea (r = 0.594, P = 0.000, nasal discharge (r = 0.314, P = 0.001, excessive daytime sleepiness (r = 0.219, P = 0.019 and failure to thrive (r = 0.240, P = 0.011. Conclusion: Lateral X-ray of the nasopharynx is an effective tool to evaluate children with suspected adenoid hypertrophy. It correlates well with patients′ symptoms and provides objective measures of adenoid hypertrophy.

    In 1978, Pratt challenged the otolaryngology community to identify an incidence of malignancy in individuals who have previously received radium therapy to the nasopharyngeal lymphoid tissues. This case report is a direct response to that quest and presents a well documented adenoid cystic carcinoma evolving 23 years after radium applicator treatment to the fossa of Rosenmuller. Although a cause-and-effect relationship cannot be scientifically proven, the case history raises several important questions concerning the stimulating effects of radiation on the later onset of frank malignancy.

    1976-09-01

    Epithelioma adenoides cysticum (EAC) is a well-known genodermatosis which follows an autosomal dominant mode of inheritance. Questions still remain, however, concerning an apparent excess of females with EAC. An analysis of nineteen previously published pedigrees and one newly ascertained pedigree, which in the aggregate included over 175 cases of EAC, induced no excess of affected females, but rather, a marked deficit males. This deficiency was not the consequence of sex linkage or decreased viability, and was most evident in large pedigrees and sibships, sibships not including the probands, and late birth orders. In these situations, the penetrance of EAC in male gene carriers was only 50%, but was close to 100% in female gene carries. Under maximum detection conditions, i.e. small pedigrees, small sibships, sibships containing the proband, and early birth orders, the penetrance in males increased to 85% and was again close to 100% in females. These findings suggested that the deficit of affected males was best explained by a comination of lessened expressivity and penetrance, effects which were magnified under situations of poor detection. A review of familial cases of EAC indicated no consistent associated anomalies such as those that characterize the naevoid basal cell carcinoma syndrome.

    Adenoid is a kind of tonsil located in the posterior wall of nasopharynx. Enlargement of the adenoid can produce obstruction of the nasopharynx and Eustachian tube. Disturbance in discharge of nasal and paranasal secretions can be a cause of chronic rhinitis, sinusitis, and otitis media. Diagnosis of enlarged adenoid simply by inspection is different due to its location. Measurement of nasopharyngeal airway and adenoid using lateral radiographs of nasopharynx may be inaccurate for magnification and rotation. It was some limitations in demonstrating the actual state of nasopharyngeal airway and adenoid because it gives only two dimensional information. The authors measured the size and areas of nasopharyngeal airway and adenoid using MRI with sagittal and oblique coronal pilot views of T1 weighted spin echo. We categorized the patients into 4 groups according to the scoring system by symptoms such as apnea, mouth breathing, and snoring. The results of several measurment and their ratios were evaluated in these 4 categorized patients. The ratios of area of adenoid and nasopharyngeal airway (AA/Na) in each patient group were 6.52, 7.76, 10.53, 15.93, respectively. And the ratios of adenoid and nasopharyngeal airway (A/N) by Fujioka's method were 0.6, 0.65, 0.69, 0.71, respectively. We found that AA/Na might be the most effective index as an objective indicator in the evaluation of nasopharyngeal obstruction by the enlarged adenoid.

    The aim of this article was to describe rarely occurred carcinoma adenoides cysticum located in the larynx, trachea and thyroid. Epidemiology, clinical course and medical therapy was demonstrated. In reported case concerning 65-year old woman early bilateral paresis of vocal folds was observed as results of the perineural infiltration. That caused sudden laryngeal dyspnea. It is important to pay attention on local extensiveness of neoplasm. Besides changes in larynx, neoplastic infiltration was found in trachea, preesophageal tissues and right lobe of thyroid. For above reasons there is no possible to exclude thyroid as a primary tumor of carcinoma adenoides cysticum.

    Radiograph of the nasopharynx is still the most commonly used imaging method to investigate the adenoidal tissue. Due to the variety and complexity of proposed methods to measure the adenoid size, some radiologists prefer subjective evaluation, which can, however, be imprecise and inaccurate. We review and describe several methods to determine the adenoid size, taking into account the practicity, accuracy and precision with the aim of pointing out the best methods to be applied in daily routine practice.

    Full Text Available Background: chronic adenoiditis, which causes the greater number of elective major surgeries in children, is a common disease in Cuba. Objectives to describe the clinical and epidemiological characteristics of chronic adenoiditis in children. Methods: a descriptive study with non-probability sampling was conducted in 98 children with chronic adenoiditis treated at the University Pediatric Hospital of Central Havana, between September 2009 and July 2011. The variables analyzed were age, sex, symptoms, signs and main clinical manifestations, personal medical history, family history, and major environmental and social risk factors. A survey was conducted to identify risk factors. Statistical analysis such as: the mean, relative frequency and frequency tables were performed. Results: highest morbidity was observed in children aged 1 to 9 years. The main features of the disease were nasal obstruction, dental malocclusion, mouth breathing and respiratory infection. The most common risk factors were attendance to day-care centers and exposure to cigarette smoke. Personal and family history of asthma and respiratory allergies was the most frequently found. Conclusion: chronic adenoiditis in pediatric patients is multifactorial in origin, and tends to decrease in the child population older than nine years.

    Full Text Available OBJECTIVES: To identify the common bacteria found in the nasopharynx of patients of serous otitis media, to study the prevalence of adenoiditis in patient of serous otitis media and to study the bacteria isolated from operated adenoid tissue of patients of serous otitis media. METHOD AND MATERIA LS : Study was carried out on clinically diagnosed 40 cases of serous otitis media. Patients were operated under general anaesthesia. At the commencement of the surgery, a sterile swab was taken with an applicator from the surface of the adenoid. Prior to surgery, the adenoid tissue was palpated and confirmed. Adenoidectomy was done by curettage method using adenoid curette and the specimen was immediately transported in normal saline to the microbiology lab in a sterile bottle along with the surface swab. RESULT: 95% culture shows bacterial growth , males are more common in serous otitis media and most bacteria isolated from nasopharyngeal swab and adenoid are Gram positive bacteria includes Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus species, Streptococcus viridians, Streptococcus pyogenes and Gram negative bacteria includes Moraxella catarrhalis, Klebsiella pneumonia. CONCLUSION: T he nasopharyngeal and adenoid bacterial flora is polymicrobial in nature and there is no difference in the pathogens isolated from nasopharynx swab or adenoid culture in patients of serous otitis media.

    The authors report the results of a study on the efficacy of topical application of the immunomodulator IRS 19 in children presenting with chronic adenoiditis and grade I-III hypertrophy of adenoid vegetation. The use of this preparation is shown to faster and more efficaciously normalize the volume of the lymphoid tissue than irrigation of the nasopharynx with saline solutions. Moreover, the treatment of chronic adenoiditis with IRS 19 promoted normalization of biocenosis of the nasopharyngeal secretion and significantly decreased the abundance of pathogenic microflora. Specifically, the overall frequency of exacerbations and the frequency of exacerbations of adenoiditis decreased three- and two-fold respectively while the duration of the disease shortened. It is recommended that the topical immunomodulator IRS 19 should be included in the programs of planned seasonal treatment of children suffering chronic adenoiditis (to be applied at least 2-3 times annually).

    2013-09-01

    To study the extent of surface adenoid biofilm and to evaluate its role in the pathogenesis of chronic otitis media with effusion (COME) in children. The study was carried out on 100 children between 3 and 14 years of age, who were divided into two groups. The first group (50 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (50 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. Microbiological study, Scanning electron microscope and multiplex- PCR were done for suspected adenoid biofilms and specimens from middle ear effusion. Adenoids removed from children with COME had higher grade biofilm formation (74 %) than the second group (42 %). No correlation was found between adenoid size and biofilm formation. Culture of adenoid tissue in group 1 patients was positive in 52 % of cases compared to 96 % by PCR, while in group 2 culture of adenoid tissue was positive in 38 % compared to 48 % by PCR. Culture of middle ear fluid was positive in 32 % of cases only compared to 80 % by PCR. A positive correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected and identified by PCR technique. On the other hand, no correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected by culture. The size of the adenoid is not the main determinant factor in OME pathogenesis but the degree of bacterial colonization is much more important. Adenoids in COME may act as a reservoir of chronic infection rather than causing mechanical Eustachian obstruction. Higher grade biofilm formation was found in cases with middle ear effusion than those with adenoid hypertrophy only. These findings support the hypothesis that there would be an association between adenoidal biofilm formation and COME. This study focused on the value of PCR

    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.

    Introduction:Patients with nasopharyngeal carcinoma (NPC) sporadically develop abnormal adenoids. Nasopharyngeal adenoids are usually included in the gross tumor volume (GTV) but may have different therapeutic responses than tumor tissue. Therefore, distinguishing adenoids from tumor tissue may be required for precise and efficient chemoradiotherapy and radiotherapy. We characterized nasopharyngeal adenoids and investigated the therapeutic responses of NPC and nasopharyngeal adenoids using magnetic resonance imaging (MRI). Methods:MRI data from 40 NPC patients with a coexisting adenoid mass before and after treatment were analyzed. The features of the adenoid masses, including location, striped appearance, size, interface, symmetry/asymmetry, and cysts, were evaluated. Treatment response were scored according to the World Health Organization guidelines. Results:A striped appearance was observed in 36 cases before treatment and in all cases after treatment. In these 36 cases, the average GTVs including and excluding the uninvolved adenoids were 19.8 cm3 and 14.8 cm3, respectively. The average percentage change after excluding the uninvolved adenoids from the GTV was 31.0%. Stable disease in the adenoids was identified in 27 (96.4%) of 28 patients after neoadjuvant chemotherapy, while NPC clearly regressed. Partial adenoid responses were identified in 33 (82.5%) of 40 patients at 3 months after chemoradiotherapy or radiotherapy, whereas complete tumor responses were achieved in all patients. Six months after treatment, the adenoids continued to atrophy but did not disappear, and tumor recurrence was not found. Conclusions:Nasopharyngeal adenoids and carcinoma tissue in NPC patients can be distinguished by using MRI and have different responses to chemoradiotherapy and radiotherapy. These findings contribute to better delineating the GTV of NPC, based on which spatially optimized strategies can be developed to render precise and efficient chemoradiotherapy and

  8. Adenoid cystic carcinoma of sublingual glands. Surgery and radiotherapy combination

    International Nuclear Information System (INIS)

    The Adenoid Cystic Carcinoma (ACC) or Cilindroma is a strange entity classified by the WHO within the carcinomas of salivary glands. It represents only 1 % of all the wicked tumours of the oral and maxillofacial region although, when making reference to the salivary glands, it constitutes 5% of the parotid, submaxilar and sublingual carcinomas, and about 50% of the smallest ones. The most frequent location is in the palatine glands and its main characteristics are: slow but persistent growth, high rates of local relapse and metastasis at distance originating the death between the first 5 and 10 years in 50-70% of the cases approximately. A case of localization is presented in sublingual gland which was first treated surgically and later with radiotherapy, obtaining good results. (author)

    Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site. PMID:25992095

    We present the case of a child with chronic adenoiditis caused by a PspK+ NESp. We tested the pneumococcal isolate, designated C144.66, for antimicrobial resistance, the presence of the pspK gene and the expression of PspK. Sequence typing and genome sequencing were performed. C144.66 was found to be resistant to erythromycin and displayed intermediate resistance to penicillin and trimethoprim/sulfamethoxazole. C144.66 has the pspK gene in place of the capsule locus. Additionally, PspK expression was confirmed by flow cytometry. NESp are a growing concern as an emerging human pathogen, as current pneumococcal vaccines do not confer immunity against them. An inability to vaccinate against NESp may result in increased carriage and associated pathology.

    Full Text Available Adenoid cystic carcinoma (ACC accounts for approximately 6-10% of all salivary gland tumors. Palatal minor salivary glands, parotid, and sub-mandibular glands are usually affected. Rarely, these lesions arising intraosseously have been reported. Mandible is commonly involved than maxilla. The present case is a giant ACC involving the right maxilla. A thorough clinical and radiographic evaluation was performed to assess the involvement of surrounding vital structures along with a meticulous metastatic work-up. Computed tomography showed a giant lesion in maxilla encroaching the left nasal fossa, antrum, buccal space, and oral cavity. No metastasis was noted. Histological evaluation from multiple sites showed both cribriform and solid patterns. Radiotherapy was given as patient did not comply for surgery. Though central ACC is extremely rare, especially in maxilla, it should be included in the differentials for lesions in maxilla. A prompt diagnosis with treatment and long-term follow-up is advised in such cases.

    The adenoids are exposed to a wide number and variety of microbes, environmental pollutants, and food antigens. Atopy and passive smoke may significantly affect immune responses, mainly in children. The aim of the present study was to investigate whether passive exposure to tobacco smoke and/or atopy could affect immunoglobulin production by adenoidal lymphocytes in a cohort of children presenting with adenoid hypertrophy. A total of 277 children (151 males and 126 females; median age 5.5 years), with adenoidal hypertrophy requiring adenoidectomy and or adeno-tonsillectomy, were consecutively enrolled in the study. Adenoid mononuclear cells were in vitro stimulated with LPS or CpG. When considering both the presence of smoke exposure and atopy, we observed that the CpG-induced decrease in IgA and IgM production was significantly associated with this combination of risk factors. In the T-independent immunoglobulin production assay we found a positive association between the two risk factors and IgA and IgM production. In particular, the presence of both risk factors, showed a significant increase in IgA and IgM production after stimulation. In conclusion, this is the first study that investigated the in vitro adenoidal B cell response after different stimuli in children, also evaluating possible exposure to passive smoke and/or an atopic condition.

    Introduction. Adenoid hypertrophy (AH) is a common childhood disorder. Adenoid plays a significant role in the pathogenesis of otitis media with effusion (OME). The aim of this study is to critically appraise the tympanometric finding among children with adenoid hypertrophy in Port Harcourt, Nigeria. Methodology. A Prospective, controlled study carried out among newly diagnosed cases of adenoid hypertrophy at the ENT clinic of the UPTH, between November 2014 and June 2015. Tympanometry was done on each child and each ear was considerably studied as a single entity. Types B and C tympanograms were used as indicators of OME. Data was collected and analyzed using SPSS version 20. Results. Sixty-eight cases of adenoid hypertrophy were seen within the study period and 136 ears were studied. Forty (29.4%) ears had type B tympanogram, while 36 (26.5%) ears had type C. The incidence of OME was 55.9%; there were 12 (17.6%) unilateral OME, while bilateral OME was 32 (47.1%). Grade 3 AH was prevalent and was statistically significant with the OME. Conclusion. This study had shown adenoidal hypertrophy as a significant risk factor for OME in children. There was more bilateral OME than unilateral. The more severe grade of AH was more prevalent and it was shown to be statistically significant with OME, thus being a significant risk factor for OME in children. This establishes the need for prompt hearing evaluation and management. PMID:27563311

    Full Text Available Background and Aim: Adenoids are normally large in children and their size starts to reduce during adolescence. Hypertrophic adenoids could be associated with allergic reactions. Enlarged adenoids result in nasal breathing difficulties and the child is forced to switch to mouth breathing. Airway obstruction causes postural alterations of jaw, tongue and head, and due to persistent obstruction, patient’s appearance changes to adenoid face. Evaluation of nasopharyngeal space in lateral cephalometic view is a simple and repeatable method for determination of the size and shape of adenoids and nasopharyngeal space which can provide a simple measurement of nasopharyngeal obstruction. The roof of nasopharyngeal space is covered by the sphenoid bone. Thus changes of nasorespiratory resistance by hypertrophic adenoids may affect the cranial base angles. In this study, the relationship between adenoid hypertrophy and cranial base angles was investigated. Materials and Methods: In this descriptive-analytic study, lateral cephalometric views of 7 to 14 y/o patients from the files of orthodontic centers in Rasht city were selected. The radiographs with proper resolution were separated for this research. Adenoid to nasorespiratory ratio (A/N Ratio was determined by Fujioka method and categorized in three groups: A (A/N 0.8, B (0.5adenoid hypertrophy (A and B groups was observed in 66% of cases whereas 34% were normal.

    Full Text Available Abstract Background Adenoid Cystic Carcinoma of the lacrimal gland is a rare tumour. Their aggressive behaviour, with a high-risk of local recurrence, and late distant spread of the tumour even after aggressive management has been reported. Metastasis to the liver is rare and when it occurs, it is usually part of widespread metastasis, and therefore surgical treatment is seldom considered. Case presentation We report a rare case of an isolated liver metastasis from a lacrimal gland adenoid cystic carcinoma 20 years after resection of the primary tumour. The patient presented with right upper quadrant pain radiating to the back and shortness of breath of 3 months duration. No local recurrence was detected during a 15 year follow-up with computerized tomography (CT of the head. Abdominal CT scan demonstrated a solitary liver tumour with no other primary source, and the bone scan was normal. The patient was treated with an extended right hemihepatectomy. The histology revealed a predominantly cribriform tumour with focal areas of basaloid type metastatic lacrimal gland adenoid cystic carcinoma. Conclusion This case illustrates the unpredictable behaviour of adenoid cystic carcinoma and the need for a life long follow up for these patients after treatment. The possibility of surgical resection for liver metastasis from adenoid cystic carcinoma should always be considered.

  18. Radiologic evaluation of adenoids and tonsils in children with obstructive sleep apnea: Plain films and fluoroscopy

    International Nuclear Information System (INIS)

    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.

    International Nuclear Information System (INIS)

    The objective of this study is to evaluate the role of radiological examination in the management of adenoidal hypertrophy. A retrospective study was carried out in the North West Armed Forces Hospital, Tabuk, Kingdom of Saudi Arabia on pediatric patients who had x-ray of lateral nasopharynx to exclude adenoidal hypertrophy, January 2001 to December 2001. The study included ; the age of patient, sex and reason for radiology examination and management rendered. A total of two hundred and ninety- seven pediatric patients were involved. Two hundred and thirteen males (71.7%) and 84(28.3%) females, age ranged between 2 months and 12 years. The reason given for radiological examination was one or more of following symptoms snoring,mouth breathing recurrent tonsillitis, runny nose, deafness and obstructive sleep apnea.Small adenoids reported in 63 patients (21.2%)and were treated for their complaints by primary physician. Two hundred and thirty four patients (78.8%) with large adenoids were referred to the otolaryngology department of these 33 patients lost follow up. One hundred and nineteen referred(40.1%) patients were treated conservatively, while 82 patients (27.6%) who showed resistance to medical treatment under went adeniodectomy with or without other related surgical procedures. It was concluded that radiological examination in the management of adenoidal hypertrophy had a limited role, increased Radiological Department workload wastage of resources in addition to unnecessary radiation exposure.

    Adenoid cystic carcinoma (ACC) is a malignant neoplasm that mainly affects the salivary glands but has been described in many other anatomical sites. It is composed of basaloid cells with myoepithelial/basal cell differentiation and ductal epithelial cells that proliferate in a fibrous stroma, with variable amounts of myxohyaline material. Three patterns (cribriform, tubular, and solid) occur, and the solid variant is characterized by a predominant compact sheet-like and nested pattern of rounded basaloid cells lacking obvious cribriform or tubular architecture. The solid variant has significant morphological and immunohistochemical overlap with a large range of neoplasms of different lineages, including other carcinomas and sarcomas. We describe a case of solid variant ACC of the paranasal sinuses, which showed an almost entirely solid pattern of growth (in >95% of cells) and which on initial biopsy showed no features of classical ACC. This highlights the potential for diagnostic misinterpretation with a variety of other neoplasms, which is particularly important because of the significant difference in treatment for ACC and tumors in its differential diagnosis.

    Summary The transcription factor MYB was recently proposed to be a promising oncogene candidate in salivary gland adenoid cystic carcinoma (ACC). However, the up-regulation of MYB in ACC could not be explained solely by deletion of its 3′ end. It is widely accepted that the promoter methylation status can regulate the transcription of genes, especially in human cancers. Therefore, it is important to know whether MYB promoter demethylation could explain the over-expression of MYB in ACC. By using the Methprimer program, we identified nine CpG islands in the promoter of MYB. All of these CpG islands were located within the −864 to +2,082 nt region relative to the transcription start site of MYB. We then used bisulfite genomic sequencing to evaluate the methylation levels of the CpG islands of MYB in 18 primary ACC tumors, 13 normal salivary gland tissues and nine cancer cell lines. Using cell lines, we also determined the relative MYB expression levels and correlated these with the methylation levels. With bisulfite genomic sequencing, we found no detectable methylation in the CpG islands of MYB in either ACC or normal salivary gland tissues. There was a variable degree of MYB expression in the cell lines tested, but none of these cell lines demonstrated promoter methylation. Promoter hypomethylation does not appear to explain the differential expression of MYB in ACC. An alternative mechanism needs to be proposed for the transcriptional control of MYB in ACC.

    There are a number of studies in the literature, that associate nasopharyngeal airway obstruction, as a result of adenoid enlargement, to the development of skeletal and dental abnormalities. However, the etiologic role of hypertrophied adenoids and tonsils in developing an aberrant dentofacial growth is not clear, yet. The present investigation attempted to study the incidence of maxillary posterior crossbite and oral habits, in a sample of 120 children, that displayed hypertrophied adenoids with or without enlarged tonsils, and underwent adenoidectomy. An attempt was also made to relate the presence of crossbite to the severity of upper respiratory airway obstruction. The severity of airway obstruction was assessed using radiographic and surgical criteria. A lateral cephalometric radiograph was obtained and studied for each patient. Results indicated, that 47% of the children examined, had developed a posterior crossbite. The presence of crossbite was high in children with severe airway obstruction, particularly in those with hypertrophied adenoids and tonsils. On the contrary, most of the children with a posterior crossbite did not have a history of pacifier or finger sucking. It was also concluded, that the study of a lateral cephalometric radiograph can be a valuable diagnostic method in the evaluation of children with upper airway obstruction.

    Full Text Available Objective. Adenoid hypertrophy is a common condition in childhood, which may be associated with recurring acute otitis media (RAOM, otitis media with effusion (OME, and obstructive sleep apnea syndrome (OSAS. These different clinical characteristics have some clinical overlap; however, they might be explained by distinct immunologic and infectious profiles and result in various histopathologic findings of adenoid specimens. Methods. A total of 59 children with adenoid hypertrophy undergoing adenoidectomy were studied. Three series of identical adenoid specimens were processed to hematoxylin-eosin (H.E. and Gram staining and to respiratory virus specific real-time PCR, respectively. Results. According to the clinical characteristics, patients were recruited into three groups: RAOM (. Bacterial biofilms were detected in 21 cases, while at least one of the studied respiratory viruses was detected in 52 specimens. RAOM cases were significantly associated with biofilm existence (. In contrast, OME group was characterized by the absence of bacterial biofilm and by normal mucosa. Showing a statistically significant correlation, all OME cases were positive for human bocavirus (HBoV, . Conclusions. Bacterial biofilms might contribute to the damage of respiratory epithelium and recurring acute infections resulting in RAOM. In OME cases persisting respiratory viruses, mainly HBoV, can cause subsequent lymphoid hyperplasia leading to ventilation disorders and impaired immunoreactivity of the middle ear cleft.

    Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Staphylococcus aureus colonization of the adenoids and nasopharynx in 103 preschool children who underwent adenoidectomy for recurrent upper respiratory tract infections was examined. Bacterial interactions and risk factors for bacterial colonization of the nasopharynx and adenoids, separately, were analysed statistically. The prevalence of simultaneous isolation from both anatomical sites was 45·6% for S. pneumoniae, 29·1% for H. influenzae, 15·5% for M. catarrhalis and 18·4% for S. aureus. Three pathogens were significantly more frequent together from adenoid samples; nasopharyngeal swabs more often yielded a single organism, but without statistical significance. M. catarrhalis and S. aureus significantly more frequently co-existed with S. pneumoniae and H. influenzae than with each other and a positive association of S. pneumoniae and H. influenzae in adenoid samples was evident. Several differences between risk factors for nasopharyngeal and adenoid colonization by the individual pathogens were observed. We conclude that the adenoids and nasopharynx appear to differ substantially in colonization by pathogenic microbes but occurrence of H. influenzae and S. pneumoniae in the nasopharynx could be predictive of upper respiratory tract infections.

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Allergic rhinitis (AR) and adenoid hypertrophy (AH) are common in children and are often associated with each other. Recent studies have shown improvement of respiratory symptoms and reduction in the adenoid volume after anti-allergic medical therapy (intranasal corticosteroids, antihistamines). The aim of our retrospective study is to evaluate the effectiveness of adenoidectomy on respiratory symptoms in pediatric patients with AR. We recruited 404 pediatric patients with AR, and we divided them into 4 groups (1. intermittent-mild rhinitis; 2. intermittent-moderate/severe rhinitis; 3. persistent-mild rhinitis; 4. persistent-moderate/severe rhinitis), using ARIA classification. For each patient we evaluated: age at onset of AR; family history of allergy; the presence of other allergic diseases; serum total IgE values; skin prick test (SPT) results; presence of AH evaluated by rhino-laringeal fibroscopy; adenoidectomy and its efficacy on respiratory symptoms. Our data show an association between AR and AH: 90 of 404 (22%) children with AR had AH of a degree greater than 2nd. A significant percentage (80%) of children suffering from AR did not present satisfactory benefits from adenoidectomy. They reported persistence or recurrence of rhinitic symptoms after surgery or only partial benefits, especially of recurrent respiratory tract infections and nasal obstruction. The local allergic persistent inflammation on nasal mucosa and adenoid tissue is probably the cause of the unsatisfactory results of adenoidectomy, therefore surgery cannot be the first therapeutic step for these children. It is important to extinguish the local inflammation by medical anti-allergic therapy to obtain improvements of nasal symptoms and to prevent adenoid regrowth.

Methods: Low metastatic and high metastatic cells of the adenoid cystic carcinoma, SACC-83 and SACC-LM, were cultured. Their subcellular fractions were extracted. The expression of epidermal growth factor receptor was detected with Western blot method, and the results of protein expression were quantitatively analyzed by FluorChem V2.0 software. Results: The results of Western blot analysis indicated that, EGFR expression on the membrane of SACC-83 cells was significantly higher than that of SACC-LM cells, but its expression in cytoplasm was significantly less in the former than the later (P<0.01). In SACC-83 cell line, EGFR was over-expressed in membrane (P<0.01), but in SACC-LM cell line, EGFR was over-expressed in cytoplasm (P<0.01). Conclusion: The results suggest that the obtaining of metastasis ability is related to the high expression of EGFR protein in cytoplasm, so the molecular targeting therapy to EGFR may be an ideal treatment for the invasion and metastasis of salivary adenoid cystic carcinoma.

    Background: Tonsilloliths are calcified concretions that develop in tonsillar crypts. They are usually small and asymptomatic, so they are found accidentally during routine dental radiogrphy procedure. Large tonsilloliths can occur with clinical signs and symptoms. The purpose of this study was to evaluate the prevalence and patterns of palatine and adenoid tonsilloliths in cone-beam computed tomography (CBCT) images. Materials and Methods: In this cross-sectional study, 0.5-mm axial and coronal slices of 134 CBCT images were evaluated to determine the presence of palatine and adenoid calcifications. Their patterns such as being unilateral or bilateral as well as single or multiple and their largest linear sizes were reported. Results: Fifty-four (40.3%) patients with palatine tonsilloliths and 17 (12.7%) with adenoid calcifications were found. Thirty (55.6%) palatine tonsilloliths were unilateral, 19 (35.2%) were detected in the left tonsils. Approximately, 54 cases of 78 palatine calcifications were multiple. Seventeen patients had adenoid calcifications that 41.1% of them were unilateral. Fourteen adenoid calcifications were single. The mean ages of patients with palatine tonsilloliths and adenoid calcifications were 45.59 years and 46.53 years, respectively. The range of linear measurements of palatine tonsil calcifications was 0.9–4.2 mm (2.47-mm mean size) while adenoid calcifications ranged from 0.5 to 2.2 mm (0.95-mm mean size). The level of statistical significant difference was <0.05. Conclusion: Gender did not affect total prevalence, the pattern of tonsilar calcifications and their linear sizes. The prevalence of tonsilloliths increased with aging, but this variable did not have an effect on their linear size. PMID:27605988

    Lower female genital tract tumors with adenoid cystic differentiation are rare, and data on their relationship with high-risk human papillomavirus (HPV) are limited. Here we report the clinicopathologic features from a case series. Tumors with adenoid cystic differentiation, either pure or as part of a carcinoma with mixed differentiation, arising in the lower female genital tract were evaluated by means of immunohistochemical analysis for p16 expression and in situ hybridization using 1 or more probes for high-risk HPV (a high-risk probe covering multiple types, a wide-spectrum probe, and separate type-specific probes for HPV16 and HPV18) and when possible by polymerase chain reaction for high-risk HPV. Six cervical carcinomas with adenoid cystic differentiation admixed with various combinations of at least 1 other pattern of differentiation, including adenoid basal tumor (epithelioma and/or carcinoma), squamous cell carcinoma (basaloid or keratinizing), and small cell carcinoma were identified in patients ranging in age from 50 to 86 years (mean, 73 y; median, 76 y). All of these tumors were characterized by diffuse p16 expression. High-risk HPV was detected in 5 of 6 tested cases: 4 cases by in situ hybridization (all positive for HPV-wide-spectrum and HPV16) and 1 by polymerase chain reaction (HPV45). Seven pure adenoid cystic carcinomas (6 vulvar and 1 cervical) were identified in patients ranging in age from 27 to 74 years (mean, 48 y; median, 48 y). All of these tumors were characterized by variable p16 expression ranging from very limited to more extensive but never diffuse. No high-risk HPV was detected in any of these pure tumors. Lower female genital tract carcinomas with adenoid cystic differentiation appear to comprise 2 pathogenetically distinct groups. Cervical carcinomas with mixed differentiation, including adenoid cystic, adenoid basal, squamous, and small cell components, are etiologically related to high-risk HPV and can be identified by diffuse

    We present a case of a 65-year-old female patient who was for the first time admitted to the clinic in 1997 due to a tuber of the tongue root. The removed tuber turned out to be histopatologically a polymorphic adenoma. The patient was re-admitted to the Clinic in 2001 due to a tuber of the tongue and of the oral cavity bottom. The tuber was removed entirely through a central incision, and an apart hypertrophic change has been found on the posterior pharynx wall and in the scar after the tracheostomy carried out during the previous surgery. In all cases carcinoma adenoides cysticum has been found, as well as metastasis into the thyroid gland and the lungs. The patient was qualified for chemotherapy in the Institute of Oncology, which she has been going through periodically every two weeks until now. In 2002 the patient was operated on a small tuber located hypodermically in the scar after the tracheotomy, which was removed. Carcinoma adenoides cysticum was found. In November 2002, during the surgery a tumorous infiltration of the thyroid gland was found comprehending trachea and reaching the mediastenum. In February 2003 the patient was re-admitted to the Clinic due to dyspnoea caused by a significant contraction of the trachea which occurred as a result of a focus of carcinoma adenoides cysticum and significantly enlarged lymph glands near the trachea. The patient was qualified for stent placement in the Institute of Pulmonary Disease and Tuberculosis (Instytut Chorób Płuc i Gruźlicy). The presented case describes an exceptionally aggressive and polyfocal regrowth and transformation of a polymorphic adenoma into cancer.

    We report a case of video-assisted thoracoscopic surgery (VATS) tracheal resection and carinal reconstruction in a patient with tracheal tumor. The patient presented with adenoid cystic carcinoma (ACC) of the distal trachea, extending along the right main bronchus with carinal invasion. The reconstruction procedure was assisted with cross-field ventilation. Postoperative clinical course of this case was good. The forced expiratory volume in the first second (FEV1) improved from 0.461 L (17% pred.) to 2.31 L (87% pred.) 1 month after the operation. VATS tracheal resection and carinal reconstruction is a feasible option for patients with tracheal tumor with carina involvement. PMID:26904230

    Four cases of rare familial multiple eccrine spiradenomas showing features of dermal cylindromas and associated with epithelioma adenoides cysticum of Brooke are reported. Skin biopsy specimens were obtained from three generations of this family and routine histochemical and immunoperoxidase stains were used. The eldest affected family member had multiple disfiguring facial and scalp tumors, which precipitated episodes of depression. Unlike other cutaneous genetic disorders, such as neurofibromatosis and tuberous sclerosis, the cutaneous adnexal tumors occurring in these patients continue to erupt and grow during their lifetimes.

    Full Text Available Adenoid cystic carcinoma (ACC is one of the most common malig¬nancy in secretory glands. It accounts for about 15% -25% of all malignant salivary gland carcinomas. Typically, ACC is slow growing tumors and develops distant metastasis via haematogenous. We report a case who presented with respiratory failure and multiple metastases. A 52-year-old male, underwent a radical craniofacial resection for a right parotid gland, followed by postoperative radiotherapy. He was followed-up with head CT scans for 5 years with no signs of locoregional recurrence. Physical examination was normal. Blood gases analyses showed moderate hypoxemia. pH; 7,49 pCO2; 31,8 Po2; 38,9 HCO3; 24,1 sat O2; 79,1. Thorax CT showed multiple lesions ranging in size from 5 mm to 4 cm distributed diffusely in both lungs. CT-guided fine-needle aspiration of the lung lesion was performed. Pathological analysis reported adenoid cystic carcinoma. Multiple pulmonary metastases may cause respiratory failure and requires constant vigilance by medical practitioners.

    Full Text Available Background. Mucociliary transport (MCT is a defense mechanism of the airway. To study the underlying mechanisms of MCT, we have both developed an experimental model of cultures, from human adenoid tissue of ciliated and secretory cells, and characterized the response to local chemical signals that control ciliary activity and the secretion of respiratory mucins in vitro. Materials and Methods. In ciliated cell cultures, ciliary beat frequency (CBF and intracellular Ca2+ levels were measured in response to ATP, UTP, and adenosine. In secretory cultures, mucin synthesis and secretion were identified by using immunodetection. Mucin content was taken from conditioned medium and analyzed in the presence or absence of UTP. Results. Enriched ciliated cell monolayers and secretory cells were obtained. Ciliated cells showed a basal CBF of 10.7 Hz that increased significantly after exposure to ATP, UTP, or adenosine. Mature secretory cells showed active secretion of granules containing different glycoproteins, including MUC5AC. Conclusion. Culture of ciliated and secretory cells grown from adenoid epithelium is a reproducible and feasible experimental model, in which it is possible to observe ciliary and secretory activities, with a potential use as a model to understand mucociliary transport control mechanisms.

    Helicobacter pylori is a well-known gastric pathogen. It plays a major role in the pathogenesis of chronic gastritis, duodenal and gastric ulcers, adenocarcinoma and gastric lymphoma. HP infection is one of the most common bacterial infections worldwide. Recently, the oral cavity was proposed as an extragastric reservoir of HP infection. HP was detected by culture and PCR in both dental plaque and saliva. It is supposed that HP infection can cause the same immunological changes in the oropharyngeal mucosa as in gastric mucosa and can also contribute to the progression of oropharyngeal diseases. HP can induce production of different cytokines and regulatory molecules, which are suggested to play a role in carcinogenesis of the oropharynx. Only a few studies have explored the presence of HP in tonsillar and adenoid tissue, where MALT is present similar to the gastric mucosa. The results of these studies were inconsistent. The question of persistence of HP in tonsillar and adenoid tissue and its role in the pathogenesis of oropharyngeal diseases still remains unclear. In this review, recent findings about oral HP are considered. Possibilities of diagnostics of HP in oral specimens are discussed. PMID:18498719

    Adenoid cystic carcinoma of the lacrimal gland is a rare tumor, although it is the malignancy most frequently arising in the gland. Treatment has been unsuccessful generally, with a 15-year survival of less than 20 percent. Our experience with this tumor in a 61-year-old woman has led to a proposal for therapeutic management based on awareness of the lesion's natural history, an understanding of regional anatomy, and familiarity with therapies reported in the literature. The feasibility of adequate tumor ablation is determined from preoperative evaluation, including CT scan, initial exploratory craniotomy, and frozen-section examination of the cranial nerves transversing the orbit. Once resectability is confirmed, "curative" intracranial and extracranial en bloc resection is performed, including the tumor, the lacrimal gland, and all contiguous structures. The defect is immediately resurfaced with and "ice cream cone" forehead flap in anticipation of adjuvant radiotherapy. An orbital prosthesis is fitted as soon as the radiation reaction subsides, and a postablative CT scan is obtained as the baseline for follow-up. It remains to be seen whether this application of the technology of CT scanning and the techniques of craniofacial surgery will improve the prognosis for adenoid cystic carcinoma arising in the lacrimal gland.

    Background:Adenoid hypertrophy (AH) is associated with pediatric chronic rhinosinusitis (pCRS),but its role in the inflammatory process of pCRS is unclear.It is thought that innate immunity gene expression is disrupted in the epithelium of patients with chronic rhinosinusitis (CRS),including antimicrobial peptides and pattern recognition receptors (PRRs).The aim of this preliminary study was to detect the expression of innate immunity genes in epithelial cells of hypertrophic adenoids with and without pCRS to better understand their role in pCRS.Methods:Nine pCRS patients and nine simple AH patients undergoing adenoidectomy were recruited for the study.Adenoidal epithelium was isolated,and real-time quantitative polymerase chain reaction (RT-qPCR) was employed to measure relative expression levels of the following messenger RNAs in hypertrophic adenoid epithelial cells of pediatric patients with and without CRS:Human β-defensin (HBD) 2 and 3,surfactant protein (SP)-A and D,toll-like receptors 1-10,nucleotide-binding oligomerization domain (NOD)-like receptors NOD 1,NOD 2,and NACHT,LRR and PYD domains-containing protein 3,retinoic acid-induced gene 1,melanoma differentiation-associated gene 5,and nuclear factor-KB (NF-κB).RT-qPCR data from two groups were analyzed by independent sample t-tests and Mann-Whitney U-tests.Results:The relative expression of SP-D in adenoidal epithelium of pCRS group was significantly lower than that in AH group (pCRS 0.73 ± 0.10 vs.AH 1.21 ± 0.15;P =0.0173,t =2.654).The relative expression levels of all tested PRRs and NF-κB,as well as HBD-2,HBD-3,and SP-A,showed no statistically significant differences in isolated adenoidal epithelium between pCRS group and AH group.Conclusions:Down-regulated SP-D levels in adenoidal epithelium may contribute to the development of pCRS.PRRs,however,are unlikely to play a significant role in the inflammatory process of pCRS.

  17. Transformation of epithelioma adenoides cysticum into multiple rodent ulcers: fact or fallacy. A historical vignette.

    Science.gov (United States)

    Howell, J B; Anderson, D E

    1976-09-01

    This historical study has examined the persistent controversy about the propensity of epithelioma adenoides cysticum (EAC) to transform into multiple rodent ulcers, by reviewing cases reported through the years that seemed to support the idea. After focusing on the biological behaviour and natural history of the tumours and comparing them with our present knowledge of the behaviour of EAC, we believe that these cases were incorrectly diagnosed. Rather than EAC, they were probably examples of the naevoid basal cell carcinoma syndrome. The latter syndrome was actually established by the recognition that patients who have multiple rodent ulcers that appear early in life and behave aggressively usually have a constellation of associated developmental defects and that the tumours sould be classified as genetically determined basal cell carcinomas and not as EAC.

    2001-01-01

    Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studied in vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observed in vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 mg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.

    White Wrolstad turkeys were each inoculated with 100,000 Eimeria adenoides oocysts and killed on days 4-14 postinoculation. Tissue samples, obtained from 4 areas of the ceca comparable to areas examined in chickens infected with E. tenella in previous studies, were processed by a modification of the osmium-thiocarbo-hydrazide-osmium technique and examined with a scanning electron microscope. The pathologic situation found in turkeys was slightly different from that in the ceca of chickens infected with E. tenella. The mucosal lesions are most severe at the proximal end of an infected cecum. Surface disruption was far less severe than with cecal coccidiosis in chickens of the same age exposed to an equal number of infective oocysts. Rupture of the epithelial cell often caused the mucosal surface to present a honeycomb appearance. Some specific stages of the life cycle were identified, including schizonts and oocysts.

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature.

    Objective: To examine expressions of chemokine receptor CXCR4 and its ligand CXCL12 in primary focus and lymphogenous metastasis of salivary adenoid cystic carcinoma (ACC) with lung metastasis. Methods: Using immunohistochemical hypersensitivity catalyzed signal amplification (CSA), expressions of chemokine receptor CXCR4 and ligand CXCL12 were detected in tissue specimens from 20 cases of primary cancer focus and lymphogenous metastasis of salivary adenoid cystic carcinoma, of which 7 cases were associated with lung metastasis and 3 with lympogenons metastasis. Twenty cases of tongue carcinoma (including 10 cases with lymphogenous metastasis) and 15 cases of mucoepidermoid carcinoma (including 5 cases with lymphogenous metastasis) were used as the malignant control group; and salivary mixed tumor ( n =10), tongue leukoceratosis ( n = 10) and cervical lymph node reactive hyperplasia ( n = 10) were used as the benign control group. Results: Expression of CXCR4 in the tissues and lymph metastases of oral and maxillofacial salivary ACC, mucoepidermoid carcinoma and tongue carcinoma was significantly higher than that of the benign control group ( P < 0.05); expression of CXCR4 in the primary focus of ACC was significantly higher than that of the malignant control group; and expression of CXCR4 in the ACC with lung metastasis was 87.1% (6/7), significantly higher than that without lung metastasis( P <0.01 ). There was evident positive expression of CXCL12 in endotheliocytes of microvessels within cancer and paracancer tissues and significantly high expression of CXCL12 in lymphogenous metastasis( P < 0.05). Conclusion: Chemokine receptor CXCR4 and its ligand CXCL12 may be associated with local invasion and lymphogenous metastasis of oral and maxillofacial cancer, especially with lung metastasis of salivary ACC.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    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

  8. Exclusive irradiation of cyst adenoid carcinomas: contribution of a dose complement in stereotactic mode

    International Nuclear Information System (INIS)

    The cyst adenoid carcinoma is a rare malignant tumor that reaches principally the salivary glands; It is characterized by a clinical aggressiveness, the presence of peri neural invasions, frequent local recurrences and a high rate of metastases dissemination at delayed distance. The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

    A 33-year-old woman presented with an unusual subglottic bulging mass accompanied by prolonged cough and wheeze. Laryngeal endoscopy revealed a bilateral, symmetrical mass immediately below the vocal cords with marked airway obstruction. Chronic subglottic laryngitis with inflammation or another condition such as amyloidosis was initially suspected. Cervicothoracic computed tomography revealed an obvious reduction of laryngeal caliber caused by an engulfing mass extending from just under the vocal cords to the cricoid ring, which was associated with thyroid, arytenoid, and cricoid cartilage destruction. Histopathological diagnosis of a biopsy specimen collected via a tracheotomy revealed that the lesion was a cT4aN0M0 adenoid cystic carcinoma (ACC) originating from the laryngeal minor salivary glands. The patient was treated by total laryngectomy with elective bilateral neck dissection under general anesthesia. Gross inspection of resected tissue confirmed yellowish-white, solid tumor mainly circumferentially encompassing the lumina of the cricoid ring. The histopathological findings confirmed typical ACC accompanied by a predominant cribriform appearance with no evidence of lymph node metastasis. The patient remains well and free of recurrence or metastasis. We herein describe laryngeal ACC and discuss radiological images and the surgical pathology. PMID:26803452

  10. Pattern of failure and role of radiotherapy in adenoid cystic carcinoma of the head and neck

    International Nuclear Information System (INIS)

    This retrospective study reviewed 55 patients with adenoid cystic carcinoma of the head and neck who were treated with radiotherapy for primary sites between 1980 and 1998. The treatment modality consisted of radiotherapy combined with surgery in 44 patients and radiotherapy without surgery in 11. Chemotherapy was also administered to 9 operated and 6 unoperated patients. The range of prescribed doses was 25-65 Gy (median 50 Gy) for patients who underwent surgery, and 60-70 Gy (median 65 Gy) for those who did not. Local failure occurred in 16 patients (29%), and 20 (36%) developed distant metastasis, which were common types of failure. Although not statistically significant different, local relapse free rates of early stage tumors were better than those of advanced stage tumors (p=0.08). The local relapse free rates were influenced by the primary sites (major vs. minor salivary glands) (p=0.04). These factors, however, had no impact on survival. Three patients developed recurrences in the skull base probably thorough perineural spread. Neck failure was also uncommon type of recurrence, occurring in only two patients. We also discuss elective irradiation to the neck nodes and the skull base. (author)

    Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

    P21 activated kinase 2 (PAK2) is a member of Group I PAKs family and highly expressed in various cancers. Current studies have demonstrated that PAK2 played a pivotal role in tumor progression. However, the role of PAK2 in salivary adenoid cystic carcinoma is still unclear. This study aims to explore the expression and the function of PAK2 in AdCC. Human salivary gland tissue microarray, including 18 normal salivary glands (NSG), 12 pleomorphic adenoma (PMA) and 72 AdCC, and immunohistochemistry were used to evaluate the expression of PAK2. The result showed that PAK2 was significantly increased in AdCC compared with NSG and PMA. Then the Pearson correlation analysis using serial tissue sections showed a close correlation of PAK2 with Cyclin D1, Phospho-STAT3 at Tyrosine 705 (p-STAT3) and Ki-67. Further in vitro study utilizing PAK2 knockdown via siRNA transfection revealed significantly reduced migration and proliferation of AdCC cell lines compared with control group. Knockdown of PAK2 decreased the expression of Cyclin D1 in AdCC cell lines. In addition, the inhibition of STAT3 reduced the expression of PAK2 in AdCC cell lines. These findings suggested that PAK2 promotes AdCC cell migration and proliferation and may be a potential therapeutic target. PMID:27648129

    Background Salivary gland adenoid cystic carcinoma (ACC) is a rare cancer, accounting for only 1% of all head and neck malignancies. ACC is well known for perineural invasion and distant metastasis, but its underlying molecular mechanisms of carcinogenesis are still unclear. Principal Findings Here, we show that a novel oncogenic candidate, suprabasin (SBSN), plays important roles in maintaining the anchorage-independent and anchorage-dependent cell proliferation in ACC by using SBSN shRNA stably transfected ACC cell line clones. SBSN is also important in maintaining the invasive/metastatic capability in ACC by Matrigel invasion assay. More interestingly, SBSN transcription is significantly upregulated by DNA demethylation induced by 5-aza-2′-deoxycytidine plus trichostatin A treatment and the DNA methylation levels of the SBSN CpG island located in the second intron were validated to be significantly hypomethylated in primary ACC samples versus normal salivary gland tissues. Conclusions/Significance Taken together, these results support SBSN as novel oncogene candidate in ACC, and the methylation changes could be a promising biomarker for ACC. PMID:23144906

    Objective: To investigate the growth inhibiting effect of tyrosine protein kinase inhibitor, genistein, on human salivary adenoid cystic carcinoma SACC-83 cell line in vitro, and its effects on the expression of CyclinB1 protein and cell cycle. Methods: Effects of genistein on the growth of SACC-83 cells in vitro were measured with MTT assay. Cell cycle was detected with flow cytometry. The expressions of CyclinB1 and Cdk1 proteins were measured with Western blot method, and the results of protein expression were quantitatively analyzed by FluorChem V2.0 software. The results were statistically analyzed by SPSS11.5 software. Results: Genistein inhibited the cell proliferation in a dose-dependant and time-dependant manner. The genistein-treated SACC-83 cells were arrested in the G2/M phase and had lower contents of CyclinB1 and Cdk1 proteins compared with the control group. Conclusion: The growth inhibiting effect of genistein on SACC-83 cells may be associated with the regulations of genistein on the CyclinB1 and Cdk1 protein expressions and the cell cycle.

    Monocyte/macrophage cells from human nasopharyngeal lymphoid tissue can be a source of bacteria responsible for human chronic and recurrent upper respiratory tract infection. Detection and characterization of pathogens surviving intracellularly could be a key element in bacteriological diagnosis of the infections as well as in the study on interactions between bacteria and their host. The present study was undertaken to assess the possibility of isolation of viable bacteria from the cells expressing monocyte/macrophage marker CD14 in nasopharyngeal lymphoid tissue. Overall, 74 adenotonsillectomy specimens (adenoids and tonsils) from 37 children with adenoid hypertrophy and recurrent infections as well as 15 specimens from nine children with adenoid hypertrophy, which do not suffer from upper respiratory tract infections (the control group), were studied. The suitability of immunomagnetic separation for extraction of CD14(+) cells from lymphoid tissue and for further isolation of the intracellular pathogens has been shown. The coexistence of living pathogens including Haemophilus influenzae, Staphylococcus aureus, and Streptococcus pyogenes with the bacteria representing normal nasopharyngeal microbiota inside CD14(+) cells was demonstrated. Twenty-four strains of these pathogens from 32.4 % of the lysates of CD14(+) cells were isolated. Concurrently, the fluorescent in situ hybridization (FISH) with a universal EUB388, and the species-specific probes demonstrated twice more often the persistence of these bacterial species in the lysates of CD14(+) cells than conventional culture. Although the FISH technique appears to be more sensitive than traditional culture in the intracellular bacteria identification, the doubts on whether the bacteria are alive, and therefore, pathogenic would still exist without the strain cultivation.

    Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-up of 79 months (range, 6-285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%-100%) and 82% (95% CI, 71%-93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%-100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%-100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%-100%) for the RT group versus 83% (95% CI, 54%-100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.

    Purpose Salivary gland adenoid cystic carcinoma (ACC) is a rare malignancy that is poorly understood. In order to look for relevant oncogene candidates under the control of promoter methylation, an integrated, genome-wide screen was performed. Experimental Design Global demethylation of normal salivary gland cell strains using 5-aza-2′-deoxycytidine (5-Aza dC) and Trichostatin A (TSA), followed by expression array analysis was performed. ACC-specific expression profiling was generated using expression microarray analysis of primary ACC and normal samples. Next, the two profiles were integrated to identify a subset of genes for further validation of promoter demethylation in ACC versus normal. Finally, promising candidates were further validated for mRNA, protein, and promoter methylation levels in larger ACC cohorts. Functional validation was then performed in cancer cell lines. Results We found 159 genes that were significantly re-expressed after 5-Aza dC/TSA treatment and overexpressed in ACC. After initial validation, eight candidates showed hypomethylation in ACC: AQP1, CECR1, C1QR1, CTAG2, P53AIP1, TDRD12, BEX1, and DYNLT3. Aquaporin 1 (AQP1) showed the most significant hypomethylation and was further validated. AQP1 hypomethylation in ACC was confirmed with two independent cohorts. Of note, there was significant overexpression of AQP1 in both mRNA and protein in the paraffin-embedded ACC cohort. Furthermore, AQP1 was up-regulated in 5-Aza dC/TSA treated SACC83. Lastly, AQP1 promoted cell proliferation and colony formation in SACC83. Conclusions Our integrated, genome-wide screening method proved to be an effective strategy for detecting novel oncogenes in ACC. AQP1 is a promising oncogene candidate for ACC and is transcriptionally regulated by promoter hypomethylation. PMID:21551254

    Full Text Available Context: Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from the salivary, lacrimal, or other exocrine glands. It is characteristically locally infiltrative in nature and has a tendency toward local recurrence, high propensity for perineural invasion, and prolonged clinical course. Aim: To analyze the presentation and natural history of cases of adenoid cystic tumors of salivary glands in our institution; and to compare with the existing literature. Design and Setting: Retrospective study at the Department of Radiotherapy. Materials and Methods: Data on 18 patients of ACC of the salivary glands treated between 2004 and 2008 were reviewed with respect to clinical presentation, stage, and histology. Results: There were 8 cases of major salivary gland tumors (47%, of which 2 were in the submandibular and 6 were involving the parotid. Ten patients (53% had minor salivary gland involvement. Two patients had metastasis at the time of presentation. All patients underwent surgery. Radiotherapy was delivered to 16 patients and chemotherapy to 6 patients (concurrent, n = 3 and adjuvant, n = 3 and no adjuvant therapy was given to 2 patients. All patients were alive at a median follow-up of 3 years. No patient developed local or distant failure during the study duration. Conclusion: ACC has locally aggressive behavior. Radiotherapy adjuvant to surgery improves local control in locally advanced disease. Longer follow-up is mandatory in view of incidence of late metastasis.

    Full Text Available Adenoid cystic carcinoma of the parotid gland is a rare and slowly growing, but highly malignant tumor. Surgical resection of a malignant parotid tumor should include resection of the facial nerve when the nerve is involved in the tumor. Facial nerve reconstruction is required after nerve resection. A 14 year-old female presented with complaints of painless enlargement of the right parotid gland and facial asymmetry. Physical examination revealed a firm mass in the region of the parotid gland as well as right facial paralysis. Biopsy obtained from the mass showed an adenoid cystic carcinoma of the parotid gland. A radical parotidectomy with a modified radical neck dissection was carried out. Grafting material for the facial reconstruction was harvested from the great auricular nerve. The proximal main trunk and each distal branch of the facial nerve were coapted with the greater auricular nerve. The patient received radiotherapy after surgery and was seen to achieve grade IV facial function one year after surgery. Thus, the great auricular nerve is appropriate grafting material for coaptation of each distal branch of the facial nerve.

    Full Text Available Introduction. The quality of our life is determined by the quality of the air that we breathe. Hence the influence of cigarette smoking and secondary exposure of persons within the smoking environment is significant. Previous studies have confirmed the influence of passive smoking to on the accumulation of given elements in the tonsils. The subject of the study is to determine the importance of ETS exposure for the accumulation of Pb, Be, Ba, Ca, Mg and Sr in the pharyngeal tonsils. Material and methods. The study involved 162 adenoids from boys and girls living in Tychy and Chorzów. exposed and not exposed to passive smoking. All biological samples were subjected to mineralization with nitric acid (V from Merck. The chemical composition of the samples was determined by the ICP – AES method. Results. The statistical analysis of the elements in the tonsils of children exposed and not exposed to ETS is performed taking into account as an additional criterion of distribution the place of residence and gender of the children. Conclusions. There was no significant effect of passive smoking on the increase of the examined metals in the adenoid. However the role of gender and place of residence to the process of accumulation of elements in this organ remains significant.

    Full Text Available Introduction. The nonsquamous carcinomas of the larynx are considered rare with the majority of malignant tumors in this area, reaching the rate of 95%, to be squamous cell neoplasms. Case Report. The case refers to a 53-year-old man that presented with symptomatology of motor nerve disease. During the evaluation of the neurologic disease, a subglottic mass of the larynx was revealed accidentally in the imaging examination. Under general anesthesia, we performed direct laryngoscopy and biopsy of the mass. The histopathologic examination revealed a hybrid carcinoma coexistence of two different carcinomas, an adenoid cystic carcinoma and an adenocarcinoma, not otherwise specified with poor differentiation. Regarding the therapeutic plan, the mass was considered inoperable due to its expansion to trachea and the patient received radiotherapy. Conclusions. Both the adenocarcinoma and adenoid cystic carcinoma are extremely rare types of malignant tumors in the larynx. The special interest of the present case is the coexistence of these two rare tumors in the same region of the larynx, being a hybrid tumor of the salivary glands in the larynx, which is the second reported case, based on our systematic literature review.

  6. Reactive oxygen species and autophagy associated apoptosis and limitation of clonogenic survival induced by zoledronic acid in salivary adenoid cystic carcinoma cell line SACC-83.

    Full Text Available Salivary adenoid cystic carcinoma is an epithelial tumor in the head and neck region. Despite its slow growth, patients with salivary adenoid cystic carcinoma exhibit poor long term survival because of a high rate of distant metastasis. Lung and bone are common distant metastasis sites. Zoledronic acid, a third generation bisphosphonate, has been used for tumor-induced osteolysis due to bone metastasis and has direct antitumor activity in several human neoplasms. Here, we observed that zoledronic acid inhibited salivary adenoid cystic carcinoma cell line SACC-83 xenograft tumor growth in nude mice. In vitro, zoledronic acid induced apoptosis and reduced clonogenic survival in SACC-83. Flow cytometry and western blotting indicated that the cell cycle was arrested at G0/G1. Zoledronic acid treatment upregulated reactive oxygen species as well as the autophagy marker protein LC-3B. Reactive oxygen species scavenger N-acetylcysteine and autophagy antagonist 3-methyladenine decreased zoledronic acid-induced apoptosis and increased clonogenic survival. Silencing of the autophagy related gene Beclin-1 also decreased zoledronic acid-induced apoptosis and inhibition of clonogenic formation. In addition, isobolographic analysis revealed synergistic effects on apoptosis when zoledronic acid and paclitaxel/cisplatin were combined. Taken together, our results suggest that zoledronic acid induced apoptosis and reduced clonogenic survival via upregulation of reactive oxygen species and autophagy in the SACC-83 cell line. Thus, zoledronic acid should be considered a promising drug for the treatment of salivary adenoid cystic carcinoma.

    Background Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome. Methods ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms. Findings Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1–306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively. Interpretation Using an international collaborative database we have created the first nomograms which

    Adenoids as a first line of host defense against respiratory microbes play an important role in majority of upper airway infectious and noninfectious illnesses. Bacterial pathogen can colonize on the adenoid tissue and probably act as a reservoir for them. To determine phenotypic and genotypic characterization of biofilm forming capacity of Staphylococcus aureus isolates from children with adenoid hypertrophy and prevalence of Panton-Valentine leukocidin (PVL) gene we collected 17 consecutive, clinically significant S. aureus isolates from children with adenoid hypertrophy undergoing adenoidectomy with one or more of the upper airway obstruction symptoms, nasal obstruction, mouth breathing, snoring, or sleep apnea. Biofilm formation was evaluated by colorimetric microtiter plate's assay. Gene encoding PVL and adhesion- or biofilm formation-encoding genes were targeted by polymerase chain reaction (PCR) assay. According to the results, all strains produced biofilm. Seven (41.2%) isolates produced strong biofilm whereas 7 (41.2%) isolates produced week and 3 (17.6%) isolates produced medium biofilm. Regarding the adhesion- or biofilm formation-encoding genes, 16 (94.1%) isolates were positive for the gene eno, 13(76.4%) for icaA, 13 (76.4%) for icaD, 10 (58.8%) for fib, 10 (58.8%) for fnbB, 4(23.5%) for can, and 1(5.8%) for fnbA. The high prevalence of genes encoding biofilms and adhesins and phenotypic ability to form a biofilm by S. aureus strains emphasizes the pathogenic character of strains isolated from children with adenoid hypertrophy.

    Full Text Available Adenoid cystic carcinoma (ACC is the most common salivary gland malignancies, with high rate of local recurrence and unpredictable prognosis. Based on previous research, prognosis of ACC in salivary gland which is correlated with survival rates, is related with histopathological malignancy degree based on its growth pattern type. This study was conducted in Pathology Anatomy Department of Medical Faculty, Padjadjaran University Bandung in 2009. The aim of this study was to analyze the alteration of immunoexpression of E-cadherin (adhesion molecule of epithelial cells and C-erbB2 proto-oncogen (the family of C-erbB/epidermal growth factor receptor in salivary gland. Adenoid cystic carcinoma correlated with cross-sectional non-random study on 51 paraffin blocks, from patients with salivary gland ACC retrospectively. The repeated histopatologic examination was to diagnose ACC and to get data of the histopathological malignancy degree (according to Szantos and Batsakis modification, and it was continued with immunohistochemistry examination of E-cadherin and C-erbB2. The alteration of negative immunoexpression of E-cadherin (82% had correlation significantly (p<0.001 with the histological malignancy degrees 1, 2, and 3 (4%, 33% and 46%. The C-erbB2 immunoexpression change had no correlation with the increasing histopatologic malignancy degree (p=0.11. The alteration of C-erbB2 immunoexpression, increased from first (5% to second degree (11% but decreased on the third degree (8%. In conclusions, the immunoexpression of E-cadherin can be used as tumor marker to predict malignancy prognosis of salivary gland ACC. The expression changes of C-erbB2 in ACC indicate its biological behavior and the main role of C-erbB2 on salivary gland ACC is in the initiation and promotion phase of carcinogenesis.

    Full Text Available Abstract Background Adenoid Cystic Carcinoma (ACC is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread. We report the first case of the 5th and 6th nerve palsy due to cavernous sinus invasion by adenoid cystic carcinoma. Case presentation A 49-year-old African American female presented to the emergency room complaining of severe right-sided headache, photophobia, dizziness and nausea, with diplopia. The patient had a 14 year history migraine headaches, hypertension, and mild intermittent asthma. Physical examination revealed right lateral rectus muscle palsy with esotropia. There was numbness in all three divisions of the right trigeminal nerve. Motor and sensory examination of extremities was normal. An MRI of the brain/brain stem was obtained which showed a large mass in the clivus extending to involve the nasopharynx, pterygoid plate, sphenoid and right cavernous sinuses. Biopsy showed an ACC tumor with a cribriform pattern of the minor salivary glands. The patient underwent total gross surgical resection and radiation therapy. Conclusion This is a case of ACC of the minor salivary glands with intracranial invasion. The patient had long history of headaches which changed in character during the past year, and symptoms of acute 5th and 6th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5th and 6th cranial nerve involvement as histopathology revealed no perineural invasion.

    The cyst adenoid carcinoma is a rare malignant tumor that reaches principally the salivary glands; It is characterized by a clinical aggressiveness, the presence of peri neural invasions, frequent local recurrences and a high rate of metastases dissemination at delayed distance. The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

    Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In the present study, we investigated the effects of a DNA methyltransferase (DNMT) inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the RECK gene and tumor invasion in SACC cell lines. Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR were used to investigate the methylation status of the RECK gene and expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment.

    Salivary gland tumors usually occur as single lesions. To have more than one tumor is unusual. We report a case of an adult male who presented with a mucoepidermoid carcinoma involving the minor salivary glands of the palate at age 57 years, followed by an adenoid cystic carcinoma of the floor of mouth at age 63 years. The patient later succumbed to non-Hodgkin lymphoma at age 72 years. There are 31 acceptable cases of multiple malignant salivary gland neoplasms reported in the world literature. Multiple malignant tumors of the same histologic type are more common than those of different histologic type. Bilateral acinic cell adenocarcinoma was the most frequent combination of multiple salivary gland malignancy, accounting for 14 cases (10 synchronous and four metachronous). All involved the parotid glands bilaterally with the exception of one case that involved parotid and submandibular gland. Polymorphous low-grade adenocarcinoma accounted for three of the four cases of multiple malignant tumors involving minor salivary glands. Individuals with a history of malignancy are at risk for the development of additional malignant tumors and should receive appropriate clinical follow-up. PMID:20614341

    Naltrexone (ReVia®) is a long-acting oral pure opiate antagonist which is approved for the treatment of alcohol addiction as a 50mg per day tablet. The mechanism of action is complete opiate blockade, which removes the pleasure sensation derived from drinking alcohol (created by endorphins). Low Dose Naltrexone ("LDN") in the range of 3-4.5 mg per day has been shown to have the opposite effect - brief opiate receptor blockade with resulting upregulation of endogenous opiate production. Through the work of Bihari and Zagon, it has been determined that the level of the endogenous opiate methionine-enkephalin is increased by LDN. Met-enkephalin is involved in regulating cell proliferation and can inhibit cancer cell growth in multiple cell lines. Increased met-enkepahlin levels created by LDN thus have the potential to inhibit cancer growth in humans. Phase II human trials of met-enkephalin, case reports published by Berkson and Rubin, and the clinical experience of Bihari confirmed the potential role of LDN in treating pancreatic and other cancers. However, large scale trials are lacking and are unlikely to be funded given the current non-proprietary status of naltrexone. A case report is presented of successful treatment of adenoid cystic carcinoma as further evidence of LDN's potential as a unique non-toxic cancer therapy. PMID:25284545

    Dinoflagellate plastid genomes are unique in having a reduced number of genes, most of which are found on unigenic minicircles of 2-3 kb. Although the dinoflagellate Adenoides eludens has larger minicircles of about 5 kb, they still carry only one gene. In addition, digenic circles of about 10 kb were detected and mapped by PCR. The non-coding regions of both unigenic and digenic circles share a number of common features including a pair of conserved cores in opposite orientation, four large families of tandem repeats and a number of double hairpin elements (DHEs). They most closely resemble the non-coding regions of the Symbiodinium psbA minicircles, but are much longer, less conserved and have an even greater variety of DHEs and tandem repeats. The presence of so many recombinogenic elements suggests models for the origin of minicircles from a multigenic ancestral chloroplast genome, and raises the possibility of recombination-directed replication rather than defined replication origins in the minicircles.

    2016-06-01

    Adenoid cystic carcinoma (AdCC) is known as a biphasic tumor composed of ductal and myoepithelial cells. The present study aimed to evaluate the amount and distribution of the myoepithelial cells in cribriform, tubular and solid subtypes of AdCC and analyze their relationship with histological grading and prognosis. A panel of myoepithelial markers including CK5/6, p63, p40, D2-40, calponin, α-SMA, S-100, and vimentin, together with a luminal cell marker CK7, and Ki-67 were used for immunohistochemical study in 109 AdCCs that included 38 cribriform, 36 tubular and 35 solid subtypes. The myoepithelial cells were labeled and found lined cystic-like paces, located at the periphery of the cribriform arrangements, and presented at the nonluminal cells of the two-layered tubular structures, while absent or dispersed in the solid pattern. Meantime, the solid subtype presented a higher proliferation rate assessed by mitotic count and Ki-67 labeling index, followed by poorer overall survival and recurrent-free survival. Furthermore, CK7 expression was found higher in solid pattern than in cribriform-tubular subtype, which showed negative correlation with the myoepithelial markers including D2-40, Calponin, α-SMA, p63, p40 and vimentin. The solid pattern of AdCC showed gland differentiation but loss of myoepithelial differentiation with a higher proliferation and more aggressiveness as well as poorer prognosis compared with the cribriform-tubular subtypes, which implies that loss of MEC differentiation might contribute to the poor prognosis of the solid subtype of AdCC. However, further studies are required to clarify its exact role in AdCC progression.

  12. Epithelial mesenchymal transition is required for acquisition of anoikis resistance and metastatic potential in adenoid cystic carcinoma.

    Directory of Open Access Journals (Sweden)

    Jun Jia

    Full Text Available Human adenoid cystic carcinoma (ACC is characterized by diffused invasion of the tumor into adjacent organs and early distant metastasis. Anoikis resistance and epithelial mesenchymal transition (EMT are considered prerequisites for cancer cells to metastasize. Exploring the relationship between these processes and their underlying mechanism of action is a promising way to better understand ACC tumors. We initially established anoikis-resistant sublines of ACC cells; the variant cells revealed a mesenchymal phenotype through Slug-mediated EMT-like transformation and displayed enhanced metastatic potential both in vitro and in vivo. Suppression of EMT by knockdown of Slug significantly impaired anoikis resistance, migration, and invasion of the variant cells. With overexpression of Slug and Twist, we determined that induction of EMT in normal ACC cells could prevent anoikis, albeit partially. These findings strongly suggest that EMT is indispensable in anoikis resistance, at least in ACC cells. Furthermore, we found that the EGFR/PI3K/Akt pathway acts as the common regulator for EMT-like transformation and anoikis resistance, as confirmed by their specific inhibitors. Gefitinib and LY294003 restored the sensibilities of anoikis-resistant cells to anoikis and simultaneously impaired their metastatic potential. In addition, the results from our in vivo model of metastasis suggest that pretreatment with gefitinib promotes mouse survival by alleviating pulmonary metastasis. Most importantly, immunohistochemistry of human ACC specimens showed a correlation between the overexpression of Slug and EGFR staining. This study has demonstrated that Slug-mediated EMT-like transformation is required by human ACC cells to achieve anoikis resistance and their metastatic potential. Targeting the EGFR/PI3K/Akt pathway holds potential as a preventive strategy against distant metastasis of ACC.

    Full Text Available Background : Mexico′s National Institute of Respiratory Diseases (NIRD is a third-level national reference center. Primary adenoid cystic carcinoma (PACC is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed. Materials and Methods: This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009. Results: We identified 9 cases of PACC (67% female out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57, and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO 2 and 28.5 mmHg for pCO 2 . Median FVC was 78%, while FEV 1 was 77% with an FEV 1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26 after the initial diagnosis. Conclusions: The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%. According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.

    2014-11-01

    Full Text Available Carcinoma of the Bartholin’s gland is very rare, comprises below 2% of Bartholin’s gland lesions and adenoid cystic carcinoma (ADC is one of the most uncommon variants and accounts for 10-15% of Bartholin’s gland malignancies. There is no consensus on treatment of ADC of the Bartholin’s gland: reported cases were treated with local excision or vulvectomy with or without lymphadenectomy followed or not by radiotherapy. The survival of patients varies significantly, so we present a case of interdisciplinary treatment of ADC resulting in 15 years’ survival. The patient was initially treated with local excision, but the margins were not clear. Then vulvectomy, inguinal lymphadenectomy and adjuvant brachytherapy were performed resulting in 7 years free of the disease. Relapses were excised by abdominoperineal amputation of the rectum and distal part of the vagina with sigmoideostomy, excisions of local recurrences in vagina and metastasectomy of isolated lung metastases. The patient died manifesting multiple lung metastases 15 years after the initial diagnosis. Based on our experience and world literature, in cases of adenoid cystic carcinoma of the Bartholin’s gland, vulvectomy with or without lymphadenectomy should be considered as a treatment of choice and in patients with positive margin, surgery should be extended by adjuvant radiotherapy.

  16. Growth of the nasopharynx and adenoidal development in Brazilian subjects Crescimento da nasofaringe e desenvolvimento da adenóide em brasileiros

    2006-03-01

    Full Text Available The purpose of this research was to study the growth of the nasopharynx and adenoid development. Lateral cephalometric radiographs obtained from 320 white Brazilian subjects between 4 and 16 years of age were used. All the participants were nose breathers and none of them had previously undergone adenoidectomy. Tracings were made from the radiographs and cephalometric measurements were performed. The results showed that adenoid sagital thickness is larger in the age group 4 - 5 years and decreases progressively. There is a slight increase in the age group 10 - 11 years, but afterwards the decrease continues. However, the nasopharyngeal free airway space does not decrease in the age group 10 - 11 years, despite the increasing thickness of the adenoid. This is attributable to the downward displacement of the hard palate, resulting in an increase of the free airway space due to growth. Although the nasopharynx follows a growth pattern similar to that of the rest of the body, adenoid tissue does not. Adenoidal development seems to differ from that of other lymphatic tissues, showing a peculiar pattern that can be revealed when hypertrophy due to infections and allergies is eliminated.O objetivo da pesquisa foi estudar o crescimento da nasofaringe e o desenvolvimento da adenóide. Foram utilizadas as radiografias cefalométricas de perfil obtidas de 320 indivíduos brasileiros brancos, cujas idades variavam entre 4 e 16 anos. Todos os participantes apresentavam respiração predominantemente nasal e não haviam sido submetidos previamente à adenoidectomia. A partir das radiografias foram feitos traçados cefalométricos, sobre os quais foram realizadas medições. Os resultados revelaram que a espessura sagital da adenóide é maior na faixa etária de 4 a 5 anos, regredindo, então, progressivamente, até a faixa etária de 10 a 11 anos, quando ocorre um leve aumento, voltando a diminuir em seguida.

Method:Clinical data of adenoid hypertrophy patients who had accepted the surgery therapy, were retrospectively analyzed;Symptoms of night snore, nasal obstruction, rhinorrhea, acouesthesia and the adenoid residue among the patients who had got three different surgerys.were compared among them. Result: Adenoid residue were found in six cases of group A. No adenoid residue were found in group B and C . Recovery of nasal obstruction and night snore in group C were much better than that in group A and B(P<0. 01,<0. 05). Conclusion:The ideal way to cure adenoidal hypertrophy is the adenoidectomy done through mouth and nose under nasal endoscope.

    Background A20, also known as tumor necrosis factor α induced protein 3 (TNFaip3), is a cytoplasmic zinc finger protein that inhibits nuclear factor kappa-B (NF-κB) activity and prevents tumor necrosis factor (TNF)-mediated programmed cell death. NF-κB is a transcription factor that regulates expression of genes involved in cell proliferation,cell survival and anti-apoptosis. Several studies have implicated that the NF-κB signal pathway is associated with angiogenesis and clinico-pathological process of adenoid cystic carcinoma (ACC) of the salivary glands.Methods The ability of overexpression of A20 to influence the biological behavior and invasion of ACC cells was examined. The cells were stably transfected with full-length A20 cDNA. Stable gene transfer was verified by realtime-polymerase chain reaction (PCR) and Western blot analysis. The change of cell biological behavior was examined by methyl thiazolyl tetrazolium (MTT) and NF-κB luciferase reporter assay and the invasion of the cells was examined by a Matrigel invasion chamber.Results pEGPFN3-A20 gene was stably transferred into ACC-2 cells and overexpressed. When cells were treated with TNFα, the NF-κB activity of ACC-2-A20 cells could be down-regulated about 46.32% in contrast to ACC-2-GFP cells (P<0.05). A20 potently inhibited growth of A20 transfectant ACC-2-A20 compared with control vector transfected groups and the ACC-2 empty control group (P<0.05). The ACC-2-A20 cells showed significantly reduced ability to invade through Matrigei-coated filters compared to ACC-2-GFP and ACC-2 cells. The inhibition rate was up to 71.05% (P<0.05).Conclusions A20 gene transfer is associated with decreased tumor invasion, in part via the down-regulation of NF-κB expression, providing evidence for a potential application of A20 in designing a treatment modality for salivary gland cancers such as ACC.

    Objective To examine the expression of cysteinyl leukotriene receptor-1 (CysLTR-1) and cysteinyl leukotriene receptor-2 (CysLTR-2) in the adenoid tissues from children with adenoid hypertrophy (AH) and to explore the role of leukotrienes in the pathogenesis of AH. Methods Sixty children with AH who were treated by adenoidectomy and/or tonsillectomy were classified into two groups: simple AH and AH plus allergic rhinitis (n=30 each). Twenty children who underwent tonsillectomy due to recurrent purulent tonsillitis were selected as the control group. The expression of CysLTR-1 and CysLTR-2 in the excised tonsil and/or adenoid tissues was determined by immunolfuorescence histochemical labeling and integrated optical density measurement. Results The expression of CysLTR-1 and CysLTR-2 in the adenoid and tonsil tissues increased signiifcantly in both the simple AH group and AH plus allergic rhinitis group compared with the control group (P<0.01). The expression of CysLTR-1 and CysLTR-2 in the AH plus allergic rhinitis group increased more signiifcantly compared with the simple AH group (P<0.01). Conclusions CysLTR-1 and CysLTR-2 are highly expressed in the adenoid tissues from children with AH, suggesting that leukotrienes are involved in the pathogenesis of AH.%目的:检测腺样体肥大(adenoid hypertrophy, AH)患儿腺样体组织中半胱氨酸白三烯受体1(CysLTR-1)和半胱氨酸白三烯受体2(CysLTR-2)的表达,探讨白三烯在AH发病中的作用。方法将60例行腺样体/扁桃体切除的AH患儿分为单纯AH组与伴变态反应性鼻炎AH组(每组30例),以反复化脓性扁桃体炎行扁桃体切除的20例患儿作为对照组。通过免疫荧光组织化学标记法及累积光密度(IOD)测量方法观察各组患儿术后扁桃体/腺样体组织中CysLTR-1和CysLTR-2的表达。结果在两个AH组的腺样体组织和扁桃体组织中,CysLTR-1和CysLTR-2的表达强度均明显高于对照组(P

    The authors discuss the characteristics and the radiotherapy treatment procedures of cystic adenoid carcinomas, and more precisely the treatment of two of such cases of nasopharyngeal carcinomas. The first one had an incomplete resection surgery followed by curing radiotherapy: he has then been in local-regional control situation for 8 months. The second one had lung metastases, was treated chemotherapy and radiotherapy (decompressive treatment), and died six months after diagnosis. Radiotherapy is considered to be the treatment basis, whereas chemotherapy is a matter of controversy. Short communication

    We report the case of a 63-year-old woman with adenoid cystic carcinoma of the lower trachea treated by resection of 11 of the 18 cartilaginous rings (61%) of the total length. The little remaining membranous portion of the carina was sewn up to create a margin for anastomosis. The anastomotic sites could be approximated by the mobilization of the cervical trachea and the left main bronchus, pulling across the traction sutures, and anteflexion of the neck. The patient's postoperative course was uneventful without any complications associated with anastomosis. Because both the proximal and distal margins showed microscopic tumors, radiation therapy was performed with 50 Gy 2 months after surgery. The patient has a good social life without recurrence 20 months after surgery. PMID:25261213

    The objective of the present retrospective study based on the analysis of 791 medical cards was to investigate microflora localized at the pharyngeal tonsil surface in the children living in the city of Chelyabinsk and presenting with exacerbation of chronic adenoiditis. 66% of the patients with this condition were 4-6 year old children. The most commonly documented were the associations composed of resident species S. alpha-haemoliticus and S. epidermidis together with pathobiontic S. aureus. S. beta-haemoliticus and S. pneumoniae occurred most frequently whereas H. influenza and some representatives of the genus Enterobacteriaceae were less numerous. Fungi of the genus Candida were identified in 25.4% of the samples at a titer above 10^4. In 23.7% of the cases, these fungi were found in the associations with S. aureus which resulted in mutual potentiation of the pathogenicity factor. PMID:26977565

OBJETIVOS: objetivou-se (a conhecer quais exames os otorrinolaringologistas solicitam para avaliar o EAN; (b verificar o conhecimento da cefalométrica por otorrinolaringologistas; (c comparar a avaliação de otorrinolaringologistas nas duas técnicas radiográficas para a medição e a visualização do EAN e da adenoide; (d correlacionar os resultados do método de inspeção visual com os da medição de Schulhof. MÉTODOS: foram obtidas, no mesmo dia, radiografias cefalométricas e de cavum de 15 pacientes respiradores bucais. Essas foram cobertas com papel cartão, deixando visível apenas o EAN e adenoides e foram avaliadas por 12 otorrinolaringologistas. Estes respondiam sobre sua familiaridade com a cefalométrica, quais exames solicitam para visualizar EAN e adenoides e se utilizam algum método de medição do grau de obstrução. Avaliavam qual das radiografias apresentava a melhor visualização da adenoide e do EAN, e classificavam o tamanho dos mesmos em pequeno, médio ou grande, através de método visual. RESULTADOS: os resultados demonstraram que todos os otorrinolaringologistas costumam solicitar a radiografia de cavum. Apenas um solicita a cefalométrica, dois estão familiarizados com essa técnica e um utiliza algum método de medição do EAN. A cefalométrica foi preferida por 49,4% dos otorrinolaringologistas, a de cavum por 22,8%, enquanto 27,8% não observaram diferença entre ambas. Foi encontrada baixa correlação entre o método de medição visual e o de Schulhof.INTRODUCTION: The lateral cephalometric as well as the cavum radiograph allow the evaluation of the nasopharyngeal airway (NAW.

    Adenoid cystic carcinoma is a frequently occurring malignant salivary gland neoplasm. We studied the induction of protease activity by the laminin-derived peptide, SIKVAV, in cells (CAC2) derived from this neoplasm. Laminin α1 and matrix metalloproteinases (MMPs) 2 and 9 were immunolocalized in adenoid cystic carcinoma cells in vivo and in vitro. CAC2 cells cultured on SIKVAV showed a dose-dependent increase of MMP9 as detected by zymography and colocalization of α3 and α6 integrins. Small interfering RNA (siRNA) knockdown of integrin expression in CAC2 cells resulted in decreased adhesion to the peptide. SIKVAV affinity chromatography and immunoblot analysis showed that α3, α6, and β1 integrins were eluted from the SIKVAV column, which was confirmed by mass spectrometry and a solid-phase binding assay. Small interfering RNA experiments also showed that these integrins, through extracellular signal-regulated kinase (ERK) 1/2 signaling, regulate MMP secretion induced by SIKVAV in CAC2 cells. We propose that SIKVAV increases protease activity of a human salivary gland adenoid cystic carcinoma cell line through α3β1 and α6β1 integrins and the ERK 1/2 signaling pathway. PMID:17591960

    目的:探讨钙粘素12(Cadherin 12,CDH12)对涎腺腺样囊性癌(Salivary adenoid cystic carcinoma,SACC)细胞侵袭和转移能力的影响.方法:以人涎腺腺样囊性癌高转移细胞株(Salivary adenoid cystic carcinoma cell line with high metastatic ability,SACC-M)为研究对象,利用CDH12小分子干扰RNA(Small interfering RNA,siRNA)对CDH12基因进行沉默,Western blot检测转染前后CDH12的表达变化.Cell Counting Kit-8法检测转染前后细胞的生长速度,体外侵袭实验比较细胞侵袭能力变化,体外迁移运动实验比较细胞运动能力的改变.结果:CDH12 siRNA明显下调CDH12基因的表达.CDH12表达下调后,SACC-M细胞体外侵袭能力显著降低,体外迁移运动能力明显降低.结论:CDH12明显地促进了SACC细胞的体外侵袭和迁移运动,提示CDH12可能在SACC的恶性进展中起着重要作用.%Objective:To study the effect of CDH12 on invasion and migration of human salivary adenoid cystic carcinoma cells in vitro. Methods:The highly metastatic human salivary adenoid cystic carcinoma cell line SACC-M was transfected by CDH12 siRNA to silence CDH12 gene. The protein expression of CDH12,before and after siRNA transfection,was examined by Western blot. Cell growth rate was determined with Cell Counting Kit-8.At the same time,the invasive capability and migration capability were evaluated by tumour invasion assay and migration assay, respectively. Results CDH 12 siRNA transfection specifically down-regulated the CDH 12 protein in SACC-M cells. The downregulation of CDH12 supressed the invasive capability and migration capability of SACC-M cells. Conclusion:CDH12 obviously promotes the invasion and migration of SACC cells in vitro. These results suggest that CDH12 may play an important role in the malignant progression in salivary adenoid cystic carcinoma.

    This study investigates whether Wnt components play a role in carcinogenesis, or the invasion and metastasis of salivary glands, also referred to as adenoid cystic carcinoma (sAdCC). Several sAdCC cell lines with low invasive potential (ACC-2), high metastatic potential (ACC-M), and higher invasive potential (T-ACC-M) were examined to determine whether Wnt components correlate with tumors' invasive and metastatic behavior. Immunohistochemistry was performed in a sAdCC tissue array. ACC-M expressed higher levels of Wnt-1, beta-catenin and lower WIF-1 compared to ACC-2 (PWIF-1 compared to ACC-2 and ACC-M. Immuno-histochemistry showed up-regulation of Wnt-1 and down-regulation of WIF-1 in sAdCC compared with normal salivary glands. Beta-catenin was found in the cytoplasm and nuclei of sAdCC. Dislocation of E-cadherin in sAdCC was observed. These results suggest that sAdCC exhibits diverse expressions of Wnt components. It has an important relationship with the invasive phenotype of these cells. PMID:26405993

    Adenoid cystic carcinoma (ACC) is an exocrine gland tumor accounting for approximately 10%-15% of all epithelial salivary neoplasms and occurs most often in the parotid and submandibular glands. Metastatic pituitary tumors are rare, and there is only 1 previously reported case of parotid ACC metastatic to the pituitary. Magnetic resonance elastography (MRE) is a dynamic magnetic resonance imaging (MRI)-based technique that measures the propagation of mechanically induced shear waves through a particular tissue to determine stiffness and offers a method to evaluate tissue consistency. We present the case of a 72-year-old woman with a remote history of parotid gland ACC and subsequent lung metastases presented after a fall that resulted in facial trauma. A non-contrast head computed tomography scan revealed a sellar/suprasellar mass, and follow-up MRI revealed a well-defined, enhancing 3.8-cm lesion. MRE showed the tumor to be firm. The tumor was resected through a transsphenoidal approach and was consistent with the MRE findings. Pathology returned as metastatic ACC. We report the second case of ACC metastatic to pituitary and the first firm pituitary tumor found by MRE and discuss the potential diagnostic value of MRE in pituitary lesions. PMID:27018011

    Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare adnexal skin tumor first described in 1975, of which merely 62 cases have so far been studied in detail and reported in the English literature. PCACC is usually regarded as apocrine in origin/differentiation, but its precise histogenesis is still not well known. PCACC has in most cases a rather indolent course but can produce local recurrences and, more rarely, regional (lymph node) and distant (pulmonary) metastases. We report herein a Greek woman with a long-standing PCACC that grew slowly over several years and produced metastasis in the regional lymph nodes, highlighting the potentially aggressive course of this tumor. The primary and metastatic tumors were studied immunohistochemically and proved to express several (sweat gland-related) antigens (such as keratin 7, epithelial membrane antigen, CD10, and CD117) but neither hormonal receptors nor p63 or Gross Cystic disease Fluid Protein 15. The salient clinicopathologic features of this rare cutaneous adnexal tumor are reviewed. PMID:23812021

    Beclin 1 plays a critical role in autophagy and functions as a haploinsufficient tumor suppressor. The expression and prognostic significance of beclin 1 in head and neck adenoid cystic carcinoma (ACC) are largely unexplored. Therefore, we investigated the expression of beclin 1, Bcl-2, and p53 in head and neck ACC tissue. Tissue samples from 35 cases (15 females, 20 males) of head and neck ACC were utilized for immunohistochemistry. Beclin 1 expression was observed in 32 cases (91.4%) and considered to be high in 15 cases (42.9%) and low in 20 cases (57.1%). Beclin 1 expression was significantly correlated with a histological growth pattern (P=0.046) and histological grade (P=0.037). Beclin 1 expression was inversely correlated with Bcl-2 expression (P=0.013) and significantly associated with overall survival (P=0.006). Bcl-2 and p53 expression were observed in 21 cases (60.0%) and 16 cases (45.7%). Bcl-2 expression was significantly correlated with perineural invasion (P=0.041) and not associated with overall survival (P=0.053). p53 expression was directly correlated with beclin 1 expression (P=0.044). Our results indicated that beclin 1 may be a novel, promising prognostic factor for clinical outcome in head and neck ACC patients and may play a part in the development of head and neck ACC by interacting with Bcl-2 and p53.

    Objective: To explore the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell and Survivin gene expression in adenoid cystic carcinoma (ACC) of lacrimal gland. Methods:ACC-2 cell in human with ACC of lacrimal gland was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin gene expression was analyzed by RT-PCR and Western blotting. Results: EGB had inhibitory effect on the proliferation of ACC-2 cell with significant dose-effect relationship, and there was statistical difference when compared with the control group (P<0.01). The inhibitory concentration 50 % (IC50) is 88 mg/L. The flow cytometer test indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell was obviously increased (P<0.05 or P<0.01). EGB had certain inhibitory effect on Survivin gene expression of ACC-2 cell, and Survivin gene expression was decreased with the increasing of the EGB concentration (P<0.01). Conclusions:EGB can effectively inhibit Survivin gene expression of ACC-2 cell in human with ACC of lacrimal gland, induce the apoptosis of ACC-2 cell and inhibit tumor cell proliferation.

    Adenoid cystic carcinoma (ACC) is an aggressive malignant neoplasm of the secretory glands. Conventional chemotherapy has poor effectiveness against metastatic ACC. Thus, a novel effective therapy is needed against metastatic ACC. A majority of ACCs (up to 94%) express c-kit. Imatinib is monoclonal antibody with specific activity against c-kit but has not been found to be effective in treating patients with ACC in which c-kit is overexpressed and activated. The NF-κB and mTOR pathways have been shown that ubiquitously and concurrently activated, indicating that the inhibition of these pathways may represent a novel treatment approach for patients with ACC. Curcumin has been shown to inhibit NF-κB and NF-κB-related pathways. 43-year-old patient was diagnosed ACC from submandibular salivary gland. After complete resection of tumor adjuvant radiotherapy was initiated. Seven years later multiple lung metastases were detected and ACC was confirmed by re-biopsy. First-line chemotherapy failed. NF-κB and c-kit were overexpressed in the metastatic specimens. Therefore, we treated the patient with metastatic chemoresistant ACC with imatinib 400mg/day and intravenous curcumin 225mg/m(2) twice a week plus oral bioavailable curcumin Arantal(®) 2×84mg/day. At 24 months, we observed near complete anatomic and complete metabolic response. To our knowledge, this is the first report of a patient with a c-kit-positive ACC that is successfully treated with the combination of imatinib and curcumin in an integrative approach. PMID:27515884

    Full Text Available Adenoid cystic carcinoma (ACC is an aggressive malignant neoplasm of the salivary glands in which c-Kit is overexpressed and activated, although the mechanism for this is as yet unclear. We analyzed 27 sporadic ACC tumor specimens to examine the biologic and clinical significance of c-Kit activation. Mutational analysis revealed expression of wild-type c-Kit in all, eliminating gene mutation as a cause of activation. Because stem cell factor (SCF is c-Kit's sole ligand, we analyzed its expression in the tumor cells and their environment. Immunohistochemistry revealed its presence in c-Kit–positive tumor cells, suggesting an activation of autocrine signaling. We observed a significant induction of ERK1/2 in the cells. SCF staining was also found in other types of non-cancerous cells adjacent to tumors within salivary glands, including stromal fibroblasts, neutrophils, peripheral nerve, skeletal muscle, vascular endothelial cells, mucous acinar cells, and intercalated ducts. Quantitative PCR showed that the top quartile of c-Kit mRNA expression distinguished ACCs from normal salivary tissues and was cross-correlated with short-term poor prognosis. Expression levels of SCF and c-Kit were highly correlated in the cases with perineural invasion. These observations suggest that c-Kit is potentially activated by receptor dimerization upon stimulation by SCF in ACC, and that the highest quartile of c-Kit mRNA expression could be a predictor of poor prognosis. Our findings may support an avenue for c-Kit-targeted therapy to improve disease control in ACC patients harboring the top quartile of c-Kit mRNA expression.

  19. Adding concurrent chemotherapy to postoperative radiotherapy improves locoregional control but Not overall survival in patients with salivary gland adenoid cystic carcinoma—a propensity score matched study

    International Nuclear Information System (INIS)

    To compare the long-term outcomes in patients with salivary gland adenoid cystic carcinoma (SGACC) treated with post-operative chemoradiotherapy (POCRT) versus post-operative radiotherapy (PORT). We retrospectively reviewed the records of 91 SGACC patients treated with surgery followed by PORT (n = 58) or POCRT (n = 33) between 2000 and 2013. Treatment outcomes between groups were compared using propensity score matching (1:1 nearest neighbor). The median radiation dose was 66 Gy, and patients were followed up for a median of 71 months. Cisplatin-based concurrent regimens were the most commonly used chemotherapy schedules. In the entire study cohort, patients undergoing POCRT showed a trend toward higher locoregional control (LRC) rates than those treated with PORT alone at both 5 and 8 years (97 and 97 % versus 84 and 79 %, respectively; P = .066). Distant metastases were the most common form of treatment failure and occurred in 31 (34 %) patients (PORT, n = 17; POCRT, n = 14). After propensity score matching (33 pairs), patients receiving POCRT had 5- and 8 year LRC rates of 97 and 97 %, respectively, compared with 79 and 67 % for patients treated with PORT alone (P = .017). The two groups did not differ significantly in terms of distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS). However, a significantly better opioid-requiring pain-free survival (ORPFS) was achieved in POCRT group (P = .038). Subgroup analyses revealed that patients with stage III − IV disease (P = .040 and .017), positive surgical margins (P = .011 and .050), or perineural invasion (P = .013 and .035) had significantly higher 5- and 8 year LRC and ORPFS when treated with POCRT, respectively. In SGACC patients, adding concurrent chemotherapy to PORT may increase LRC and ORPFS rates, particularly in presence of stage III − IV disease, positive surgical margins, or perineural invasion. However, no significant differences in DMFS, DFS, and OS were

    Adenoid cystic carcinoma (AdCC) of the breast is an uncommon but distinct neoplasm composed of a dual cell population polarized around true glandular (luminal) spaces and pseudolumina. The aim of this study was to clarify whether various immunohistochemical markers (CK7, EMA, CD117, p63, calponin, CD10, S100, CK5/6, CK14, vimentin, and type IV collagen) can distinguish between the two cell types in classical AdCC (n = 14) and in collagenous spherulosis (n = 5). The sensitivity and specificity of these 11 markers to distinguish luminal from abluminal cells were evaluated using a curve created by plotting the true-positive rate (sensitivity) against the false-positive rate (1 - specificity) at threshold settings of 0, 10, 50, and 70 %. The most sensitive and specific markers for luminal cells in AdCC were CK7 and EMA; those for abluminal cells were type IV collagen, p63, and vimentin. CD10 and S100 did not act as abluminal markers in AdCC. CK5/6, one of the basal/myoepithelial markers, was expressed more frequently in luminal than in abluminal cells of AdCC. Thus, CK5/6 immunostaining resulted in a reverse expression pattern, analogous to what we recently documented in clear cells in mammary adenomyoepithelioma. In conclusion, compared with myoepithelial/abluminal cells of normal breast or collagenous spherulosis, the neoplastic abluminal cells of classical AdCC are characterized by enhanced vimentin and attenuated CD10 and S100. Furthermore, the luminal cells of AdCC show a unique aberrant staining pattern for CK5/6 that may aid in the differential diagnosis. PMID:27240462

    Purpose To investigate the clinicopathologic features of cervical adenoid basal cell carcinoma. Methods Clinical and pathological data were analyzed in 12 cases of cervical adenoid basal cell carcinoma and the relevant literatures were reviewed. Results The age of 12 cases of with cervical adenoid basal cell cancer patients ranged from 36~70 years ( mean:53. 3 years) , with a medi-an age of 51. 5 years. Amongst 12 patients who contained no gross definite lesion, 5 patients (41. 7%) had the symptoms of vaginal bleeding. 8 cases of patients underwent hysterectomy, while the other four received cervical conization. Cervical intraepithelial neopla-sia ( CIN) lesions were observed in all 12 cases. The tumor cells were small and uniform, with dark oval nuclei without conspicuous nucleoli and scanty cytoplasm. Tumor infiltrated into the stroma in nests and cords. Glandular differentiation within tumor nests were seen in 12 cases, including two cases of squamous cell differentiation accompanied by partial and minor interstitial edema. Peripheral palisading cells around tumor nests were also found. The infiltrating depth of tumor ranged from 0. 5~10 mm with the average 4. 12 mm. Cancer embolis were available in 2 cases with no lymph node metastasis. 10 cases followed up for 3~78 months with no recur-rence and metastasis, but 2 cases were lost. Conclusion Adenoid basal cell carcinoma is a rare uterine cervical tumor found in post-menopausal women, which are often accompanied with CIN. This tumor has a favorable prognosis and should be clearly separated from adenoid cystic carcinoma and other tumors which also have infiltrative growth pattern.%目的:探讨子宫颈腺样基底细胞癌的临床病理学特征。方法回顾性分析12例子宫颈腺样基底细胞癌患者的临床病理资料、组织学特征及免疫表型,并复习相关文献。结果12例子宫颈腺样基底细胞癌患者年龄36~70岁,平均53.3岁。5例(41.7%)有阴道出血症状,12例中8

  6. The T-box transcription factor Brachyury regulates epithelial–mesenchymal transition in association with cancer stem-like cells in adenoid cystic carcinoma cells

    International Nuclear Information System (INIS)

    The high frequencies of recurrence and distant metastasis of adenoid cystic carcinoma (AdCC) emphasize the need to better understand the biological factors associated with these outcomes. To analyze the mechanisms of AdCC metastasis, we established the green fluorescence protein (GFP)-transfected subline ACCS-GFP from the AdCC parental cell line and the metastatic ACCS-M GFP line from an in vivo metastasis model. Using these cell lines, we investigated the involvement of the epithelial–mesenchymal transition (EMT) and cancer stem cell (CSCs) in AdCC metastasis by real-time RT-PCR for EMT related genes and stem cell markers. Characteristics of CSCs were also analyzed by sphere-forming ability and tumorigenicity. Short hairpin RNA (shRNA) silencing of target gene was also performed. ACCS-M GFP demonstrated characteristics of EMT and additionally displayed sphere-forming ability and high expression of EMT-related genes (Snail, Twist1, Twist2, Slug, zinc finger E-box binding homeobox 1 and 2 [Zeb1 and Zeb2], glycogen synthase kinase 3 beta [Gsk3β and transforming growth factor beta 2 [Tgf-β2]), stem cell markers (Nodal, Lefty, Oct-4, Pax6, Rex1, and Nanog), and differentiation markers (sex determining region Y [Sox2], Brachyury, and alpha fetoprotein [Afp]). These observations suggest that ACCS-M GFP shows the characteristics of CSCs and CSCs may be involved in the EMT of AdCC. Surprisingly, shRNA silencing of the T-box transcription factor Brachyury (also a differentiation marker) resulted in downregulation of the EMT and stem cell markers. In addition, sphere-forming ability, EMT characteristics, and tumorigenicity were simultaneously lost. Brachyury expression in clinical samples of AdCC was extremely high and closely related to EMT. This finding suggests that regulation of EMT by Brachyury in clinical AdCC may parallel that observed in vitro in this study. The use of a single cell line is a limitation of this study. However, parallel data from in vitro and

    Full Text Available A tonsila faríngea ou adenóides é a extensão superior do anel linfático de Waldeyer e está localizada na porção alta da cavidade nasofaríngea, próxima à tuba auditiva e à coana. Ela desempenha um papel relevante nas otites médias recorrentes e freqüentemente sua hipertrofia é responsável pela obstrução das vias aéreas superiores. A tonsilectomia é um tratamento comumente realizado para doenças crônicas das tonsilas e ainda é o procedimento cirúrgico mais freqüente e mais antigo realizado em crianças e adultos jovens. Os critérios para a realização da tonsilectomia, o efeito da mesma na integridade imunológica do paciente e seus riscos inerentes à cirurgia são muito discutíveis e controversos em todo o mundo. Estudos de imagem utilizando-se o raio-X do cavo é um método simples, fácil e confortável para avaliar o tamanho das adenóides e o grau de obstrução das vias aéreas superiores. Um estudo nasofibroscópico da nasofaringe pode fornecer uma informação melhor sobre essa região, tendo em vista que ele mostra todas as estruturas presentes na nasofaringe e o grau de obstrução das vias aéreas superiores de forma dinâmica. FORMA DE ESTUDO: Clínico não randomizado. MATERIAL E MÉTODO: Este estudo comparou o grau de hipertrofia e de obstrução das vias aéreas superiores, usando os dois métodos acima, em crianças de 3 a 10 anos de idade, constatando que a nasofibroscopia flexível é um método diagnóstico excepcionalmente mais fidedigno do que o raio-x do cavo, na avaliação volumétrica da adenóide.The pharyngeal tonsil (adenoid constitutes the upper portion of the Waldeyer's ring and is located at the top of the nasopharynx, next to the auditory tube and choana. It plays an important role in recurrent otitis of the middle ear and many times its enlargement is responsible for upper airway obstruction. Tonsillectomy is often the treatment of choice for tonsillar diseases. So far, it is the most

    We analyzed 41 oral salivary gland carcinomas from consecutive 290 salivary gland carcinoma database (14%) with emphasis on the histological spectrum and clinical outcome of adenoid cystic carcinoma (ACC) and polymorphous low-grade adenocarcinoma (PLGA). The cohort included 14 ACCs, 14 mucoepidermoid carcinomas (MECs), 8 PLGAs, 3 adenocarcinomas, not otherwise specified and 2 acinic cell carcinomas. Mean age was 48, 58 and 61 yrs for ACC, MEC and PLGA, respectively. Eight patients (19.5%) died of tumor at a mean interval of 66.5 months. ACC and PLGA showed similar mean age, gender distribution, predominant palatal localization, nodal metastasis, perineural invasion and MIB-1 index. However, ACC tended to show higher tumor stage and residual tumor (R1/R2) more frequently than PLGA, but this was statistically not significant. ACC and PLGA showed overlapping architectural patterns. However, ACCs displayed well organized basal-luminal differentiation, highlighted by CK5/CK7 immunostaining. In contrast, PLGA showed a disorganized histological and immunohistological pattern. C-Kit expression (CD117) was common in ACC, generally mirroring that of CK7 and virtually lacking in PLGA. Kaplan-Meier analysis demonstrated a similar clinical course for ACC and PLGA with 5 years survivals of 87% and 80%, respectively. Fluorescence in situ hybridization (FISH) performed on all 290 salivary carcinomas confirmed the specificity of the translocation t (11; 19) for MEC and its absence in all other carcinomas including ACC and PLGA. Our results emphasize the diversity of oral salivary gland carcinomas and the overlapping clinicopathological features of ACC and PLGA.

    Full Text Available Objectives: This study was organized to assess the relationship of enuresis nocturna (EN and upper airway obstruction (UAO in children. Material and Methods: This study was multi-centrically and prospectively designed including 79 children who presented to a urology clinic with symptoms of EN between January 2013 and February 2014. Sixty-four age-matched children with no history of urological complaints were randomly recruited from children admitted to a pediatric clinic as a control group. All children and parents were asked to fill out a dysfunctional elimination syndrome (DES questionnaire and children were examined by an ear, nose and throat (ENT specialist to evaluate the UAO. Descriptive statistics, chisquare and Mann-Whitney-U tests were used to compare variables. Results: The mean ages of the 79 children (48 male, 31 female in the study group and the 64 children (41 male, 23 female in the control group were 10.14+/-3.38 and 9.17+/- 2.85, respectively. Family history of the study showed that 19% of the children’s mothers, 10% of the children’s fathers and 37% of the children’s siblings had experienced EN. There was a significant difference between the study and the control groups in terms of urge to urinate, bladder emptying, bowel symptoms and psychological stress. There was also a significant difference between rates of tonsillar hypertrophy and nasopharynx obstruction in the EN group (p = 0.009. Conclusion: In this study we found that half of the children with EN had tonsillar hypertrophy, which was significantly higher than in the control group. Further studies are needed to clarify the exact relationship between UAO and EN.

    PURPOSE: To detect the expression of p65, a subunit of NF-κB proteins, and apoptosis after adenoid cystic carcinoma cells (ACC-2) irradiated by high energy X-ray, and to investigate the interaction between them. METHODS:ACC-2 cells were cultured and then irradiated by high energy X-ray of different dose (2, 4, 6, 8,10Gy). At the next six time points (1, 3, 6, 10, 24, 48h), the expression of p65 protein in cytoplasm and nucleus was detected by immunocytochemistry and Western blotting. The apoptotic cells were counted by flow cytometry and then observed by TUNEL technique. The data of radiant intensity and apoptotic rate were statistically analyzed by Spearman method with SPSS11.5 software package. RESULTS: In ordinary condition, p65 protein seldom appeared in the nucleus, and mostly stained in the cytoplasm by immunocytochemistry. After irradiation, the protein was observed around the nuclear. Then it went through the nuclear membrane more and more as time going on, finally to the center of the nucleus. The quantity of p65 among the total protein changed gradually after radiation, rising at first, which got to a peak after about 6 to 10 hours,according to the results of Western blotting. At the same time point, p65 protein was found to have a higher expression with a higher dose of irradiation correspondingly. The proportion of apoptotic cells also varied from time to time, and an obvious valley of the apoptotic curve was at the 10th hour after radiation. Compared with the outcome of Western blotting,the results indicated a negative correlation between the apoptotic rate and the radiant intensity or p65 protein expression (P<0.05). CONCLUSIONS: The expression of p65 protein is affected by the irradiation of p65 of high energy X-ray,which is dose-time dependent. The proportion of apoptotic cells decreases as the expression increases. Supported b Shandong Provincial Science and Technology Development Plan(2006GG2202034).%目的:将唾液腺腺样囊性癌ACC-2细

    72 consecutive patients with ACC were treated with fast neutrons, 66 after surgery, 6 for primarily unresectable disease, 43/66 for macroscopic residual disease, 23/66 for unresectable recurrent disease. 45/72 tumors were localized in the minor, 27 in the major salivary glands. T-stage was in 13 pts T2, in 33 T3, in 26 T4; positive nodes were in 10 pts. M+ in 15 pts. Mean tumor volume was 89 cm3. Neutron therapy was 15.03 Gy in 3 weeks with 1.67 Gy per fraction three times per week. Individual computer assisted treatment planning was performed based on CT and/or MRI, using bolus material if necessary. Target volume was the macroscopic tumor volume with a generous safety margin. Results: Complete response was achieved in 28 pts, partial response in 35 pts. Local control was observed in 73.4% after a mean observation period of 36 months. Overall and recurrence free survival was 85%/81% at two years, and 58%/53% at 5 years (Kaplan-Meier). In univariate analysis tumor volume (> 100 cm3), distant metastases, histologic subtype (solid) and neutron dose (<15 Gy) turned out to be significant parameters for predicting outcome, in multivariate analysis tumor volume and histologic subtype remained the only significant parameters. Acute morbidity was grade III/IV (EORTC/RTOG) in 6% for skin (desquamation), in 4% for mucosa (ulceration), late morbidity (grade III/IV) in one patient with local temporal brain necrosis. (orig.)

    Studied was the anticoccidial activity of the preparations monensin, salinomycin, lassalocid, lerbek, arpocox, and chimcoccid in the prevention of coccidiosis in turkey poults infected with Eimeria adenoeides. A total of 80 turkey poults were used. The prophylactic effect produced by the coccidiostatics was recorded as judged by the anticoccidial index, the liveweight at the beginning and at the end of the experiment, the amount of food intake, and the index of feed conversion. Best effect was produced by chimcoccid which was to be preferred to the other preparation in the prophylaxis of turkey cocidiosis. Comparatively good results were likewise obtained with the use of lerbek, followed by salinomycin and arpocox. Monensin and lassalocid ranked last.

    In malignancies that have a propensity for PI such as ACC, patients may present atypically with nerve palsies. In infiltrative lesions, the primary tumour may not be evident on magnetic resonance imaging. Therefore, to achieve a diagnosis, a high index of suspicion is required. When the diagnosis is in question, deep biopsy and positron emission tomography may be useful.

    Full Text Available ACC is a rare malignant tumor that affects most commonly the major and minor salivary glands and rarely the paranasal sinuses, lacrimal gland, larynx, ear, vulva, and so forth. The maxillary sinus when affected is considered having a poor prognosis due to delayed diagnosis and delayed treatment credited to its slow spread, late symptoms, and complex anatomy which hampers surgical resection. The expressions of tumor markers too have a significant role in determining the prognosis. The treatment of choice consists of wide radical resection of the tumor followed by radiotherapy. Rehabilitation options in cases with huge maxillary defects still need further exploration.

    The aim of our study was to assess the efficacy and safety of endoscopic coblator adenoidectomy compared to cold curettage in paediatric patients. Forty homogeneous children (4-16 years of age) with adenoid hypertrophy were divided in 2 groups to receive adenoidectomy using cold curettage (A) or coblator (B). After surgery the following outcomes were evaluated: pain score on first day, days reporting pain, analgesic days, liquid diet days, absent from school days, pain score, days with nausea, days with fever, endoscopic adenoid grade and intraoperative bleeding. Forty days after surgery, basal rhinomanometry and nasal decongestion test were measured. The coblation group reported significantly less pain on the first post-operative day, days reporting pain, analgesic days, liquid diet days and absent school days. Patients in group A showed a higher grade of adenoid persistence by rhinoendoscopy, with high values of nasal resistances at the rhinomanometry even after nasal decongestion, consistent with greater adenoid persistence after cold curettage causing air flow obstruction even after turbinate decongestion. Intra-operative bleeding during coblation was significantly less compared the group undergoing cold curettage. Coblator treatment significantly improved patient recovery compared to curettage. Endoscopic coblation adenoidectomy ensures complete removal of adenoids and reduces postoperative adenoid grade. It can also be considered safer because it is under endoscopic control and can reach the cranial portion of the adenoid and its intranasal extension.

    Full Text Available OBJECTIVE: To investigate the contributions of adenoid and tonsil size to childhood obstructive sleep apnea (OSA and the interactions between adenotonsillar hypertrophy, age, and obesity in children with OSA. METHODS: In total, 495 symptomatic patients were recruited. The patients were assigned to four groups according to age: toddler (age 1-3, n=42, preschool (age 3-6, n=164, school (age 6-12, n=200, and adolescence (age 12-18, n=89. All subjects had tonsil size graded by otolaryngologists, adenoid size determined on lateral radiographs (Fujioka method, and a full-night polysomnography. The apnea-hypopnea index (AHI, adenoid size, and tonsil size were compared in obese and non-obese children in the four age groups. Adjusted odds ratios (ORs and 95% confidence interval (CI of adenotonsillar hypertrophy and OSA risk were estimated by multi-logistic regression. RESULTS: The AHI was positively related to tonsil grade (r=0.33, p <0.001 and adenoid size (r=0.24, p <0.01 in all patients. Tonsil grade was positively related to AHI in all four age groups. Adenoid size was positively related to AHI in the toddler, preschool, school groups, but not in the adolescent group (r=0.11, p=0.37. Tonsil grade and adenoid size were both positively related to AHI in obese and non-obese children. In the regression model, obesity (OR=2.89; 95% CI 1.47-5.68, tonsillar hypertrophy (OR=3.15; 95% CI 2.04-4.88, and adenoidal hypertrophy (OR=1.89; 95% CI 1.19-3.00 significantly increased OSA risk. CONCLUSIONS: Adenotonsillar hypertrophy and obesity are the major determinants of OSA in children. However, the influence of adenoid size decreases in adolescence.

    Tonsillectomy and adenoidectomy (T&A) is currently recommended in children with Obstructive Sleep Apnea (OSA). However, the condition persists after surgery in about one third of cases. It has been suggested that Drug Induced Sleep Endoscopy (DISE) may be of help for planning a more targeted and effective surgical treatment but evidence is yet weak. The aim of this review is to draw recommendation on the use of DISE in children with OSA. More specifically, we aimed at determine the proportion of cases whose treatment may be influenced by DISE findings. A comprehensive search of articles published from February 1983 to January 2014 listed in the PubMed/MEDLINE databases was performed. The search terms used were: "endoscopy" or "nasoendoscopy" or "DISE" and "obstructive sleep apnea" and "children" or "child" or "pediatric." The main outcome was the rate of naive children with hypertrophic tonsils and/or adenoids. The assumptions are that clinical diagnosis of hypertrophic tonsils and/or adenoids is reliable and does not require DISE, and that exclusive T&A may solve OSA in the vast majority of cases even in the presence of other concomitant sites of obstruction. Five studies were ultimately selected and all were case series. The median (range) number of studied children was 39 (15-82). Mean age varied from 3.2 to 7.8 years. The combined estimate rate of OSA consequent to hypertrophic tonsils and/or adenoids was 71% (95%CI: 64-77%). In children with Down Syndrome, the combined estimated rate of hypertrophic tonsils and/or adenoids was 62% (95%CI: 44-79%). Our findings show that DISE may be of benefit in a minority of children with OSA since up to two thirds of naive cases presents with hypertrophic tonsils and/or adenoids. Its use should be limited to those whose clinical evaluation is unremarkable or when OSA persists after T&A.

  16. Inflammatory cytokine detection in adenotonsill and peripheral blood mononuclear cells- culture in adenotonsillectomy patients: a comparative study

    2013-04-01

    Full Text Available Background: Tonsils and adenoid hypertrophy is a major respiratory symptom in children which is partly due to recruitment of inflammatory cells in upper airway lymph nodes as a result of the effects of synthesis and release of different inflammatory cytokines. It seems that infections play role in concert with these cytokines leading to tonsilar hypertrophy and other pathologic consequences. It is proposed that cellular infiltrate of tonsils and adenoids may secrete different quantities of these cytokines compared with peripheral blood mononuclear cells (PBMC cultures.Methods: Among patients who were admitted for adenotonsillectomy to the ENT ward, 37 patients, under 1-12 years old patients with fulfill criteria selected to include the study. Excised adenoid and tonsils cultured and inflammatory cytokines Interferon-γ (INF-γ, Interlukine-1 (IL-1, IL-6, IL-8 and tumor necrosis factor-α (TNF-α measured in cellular culture supernatant. The same cytokines measured in PBMC cultures.Results: The data shows that there is a significant difference between IFN-γ and IL-8 amounts in adenoid tissue culture supernatant and PBMC culture of our patients. Furth-ermore, the amounts of IFN-γ, IL-1 and IL-8 showed considerable difference between tonsilar tissue culture supernatant and PBMC culture of these patients. Although there is a significant correlation between IL-6 amounts in tissue culture supernatant and PBMC culture (P=0.02, the respective data for TNF is only almost significant.Conclusion: Inflammatory cytokines may have significant role in the early provoke of inflammation occurred in hypertrophied tonsils and adenoid. The majority of these cyt-okines increase the expression of adhesion molecules on epithelial cells and influence the recruitment of leucocytes and inflamed tonsils. On the other hand lack of sufficient cytokine release may lead to persistent infections and may cause chronic inflammation and hypertrophied tissue.

  17. CT and MRI features of perineural tumor spreading along the trigeminal nerve in malignant head and neck tumors

    International Nuclear Information System (INIS)

    Objective: To study the imaging features regarding perineural spread of tumor along the trigeminal nerve in malignant head and neck tumors, investigate its usefulness in improving diagnostic accuracy and palnning for clinical treatment. Methods: Images in 9 patients with clinical or radiological findings suggestive of perineural spread along trigeminal nerve were retrospectively studied. Results: Among the 9 patients, 6 were adenoid cystic carcinoma of the hard palate (n=3), maxillary sinus (n=1), parotid gland (n=1) and buccal space (n=1), respectively. Two were nasopharyngeal carcinoma and 1 was squamous carcinoma of the maxillary sinus. Enlargement and fat effacement of greater palatine foramen and pterygopalatine fossa distant from primary diseases were seen in all the 3 patients with adenoid cystic carcinoma of the hard palate and 1 with squamous carcinoma of maxillary sinus, furthermore, enlargement of foramen ovale and invasion of meckal cave was seen in 1 case. Erosion of infraorbital foramen and enlargement of the pterygopalatine fossa was seen in 1 patient with adenoid cystic carcinoma of maxillary sinus. Enlargement of pterygopalsatine fossa and foramen rotundum and invasion of the Meckal cave were seen in 1 patient with adenoid cystic carcinoma of buccal space. Perineural spread along auriculotemporal nerve and intracranial invasion through foramen ovale were seen in 1 patient with adenoid cystic carcinoma of parotid gland. Enhancement of mandibular nerve was seen in 2 patients with nasopharyngeal carcinoma. Conclusion: Perineural tumor spread along trigeminal nerve can be seen in malignant head and neck tumors, and knowledge of the anatomy of trigeminal nerve and its surrounding structures is important for correct diagnosis.

    Full Text Available Aim of our study is to compare the efficacy and safety of coblation adenoidectomy versus conventional cold steel adenoidectomy. The study design included 40 children between age groups 4 – 8. Twenty of these children underwent coblation adenoidectomy while the other group of 20 underwent conventional cold steel adenoidectomy. The parameters taken into consideration for comparison included Post operative pain, operating time, intraoperative bleeding and presence of residual adenoid tissue 6 weeks after surgery. In this study the coblation group demonstrated less post operative pain, less intraoperative bleeding and more complete removal of adenoid tissue. Operative time was found to be significantly higher in coblation group when compared to conventional cold steel adenoidectomy group.

  1. Assessment of nasal obstruction with flexible nasal endoscopy

    International Nuclear Information System (INIS)

    Objective was to report the value of nasal endoscopy as an outpatient procedure in the diagnosis of posterior nasal obstruction. Over one year period, from March 2002 to March 2003, we evaluated 130 adult patients that attended the Ear, Nose and Throat Department of Sohag University Hospital in Egypt with persistent nasal obstruction via anterior rhinoscopy and flexible nasopharyngoscopy. We reported the cause and site of obstruction in relation to the choanae. We confirmed the diagnosis by CT scanning, rigid endoscopic examination under general anesthesia, and histopathological analysis of biopsies taken. Forty-six percent of our cases had posterior nasal obstruction, 43.5% due to post-choanal lesions (mainly adenoid), 33% due to pre-choanal lesions (mainly choanal polyps), and 23.5% due to choanal lesions (mainly choanal adenoid). We conclude that flexible nasal endoscopy is superior to visual examination in the evaluation of nasal obstruction; hence, we recommend its routine use. (author)

    Monensin was effective within the range 60-100 p.p.m. in control of coccidiosis in turkey poults in a series of laboratory experiments. Under conditions of heavy infections with Eimeria meleagrimitis and E. adenoides, 100 p.p.m. of monesin was significantly more effective than 60 p.p.m. in protecting weight gains. When light or moderate infections with E. meleagrimitis, E. adenoides and E. gallopavonis were used, there were no significant differences among monesin-medicated treatments. In all instances the monensin-medicated treatments gained significantly more weight than noninfected, nonmedicated controls, when measured at 7 days post-inoculation. Similarly, oocyst, passage was reduced, feed conversion was protected and mortality was controlled in monensin-treated poults.

    1989-01-01

    The relationship between hypoplasia of the upper maxillary bone and nasal respiratory insufficiency in a group of twenty infants with malocclusion being treated by rapid maxillary expansion (RME) were studied. Prior to treatment all patients presented endognatia with discrepancies of from -4 to -7 mm in the transverse basal skeleton. These were often associated with adenoid hypertrophy (70% of the cases), increased total nasal resistance (70%), oral respiration (80%) and middle ear diseases (30%). RME led to resolution of occlusion alterations in all cases and often also brought about a regression in adenoid hypertrophy (57% of the cases), normalization of the total nasal resistance (70%) and respiration (80%). These effects were achieved alone without association with any other form of medical or surgical E.N.T. treatment. The functional results confirmed by the radiological and clinical findings indicate an increase in the diameters of the nasal fossa and in the distance between the canines, between premolars and between molars as well as reduction in adenoid vegetation and in the diffuse hypertrophic tissues lining the naso-pharyngeal space. Nonetheless, hypoplasia of the upper maxillary bone and nasal respiratory insufficiency remain strictly linked and are bound to a variable, and at times uncertain, cause-effect relationship. Is nasal stenosis the moving force of maxillary-mandibular dysmorphism and gnatological dysfunction or does it result from an overall genetic conditioning of facial skeleton development? During their vast experience in adenoid and metadenoid pathologies in infancy the authors have, at times, observed significant maxillo-facial dysmorphisms. They have likewise found that "facies adenoidea" were not always associated with hypertrophy of the pharyngeal tonsil.(ABSTRACT TRUNCATED AT 250 WORDS)

    Obstructive diseases of children's upper airways are frequent, mostly caused by tonsils and adenoids hypertrophy. A nasal septum deviation or a lower turbinate hypertrophy may also cause a significant obstruction. Tonsillectomy and adenoidectomy must be performed in case of clinical obstruction, sometimes documented by a sleep study. A tonsils' hypertrophy without significant obstruction and clinical symptoms is not an indication of adenotonsillectomy, even in case of snoring or if an orthodontic treatment is planned.

    Conclusion: The SPA is similar to the fibrocystic changes, sclerosing adenosis and adenoid tumors of the mammary gland. The main location of the SPA is the parotid gland and it is considered a disease due to a pseudotumoral inflammatory reaction with a possible association with the Epstein–Barr virus. There is evidence that monoclonal cell populations exist. The treatment consists in excision of the tumor with a superficial parotidectomy, which has demonstrated high cure rates.

    The Brooke-Spiegler syndrome is an autosomal dominant one characterized by cylindromas, trichoepitheliomas and occasionally spiradenomas. Within a given family, some members may have cylindromas whereas others may have trichoepitheliomas or both. We describe the coexistence of trichoepithelioma papulosum multiplex (also known as epithelioma adenoides cysticum of Brooke) and cylindromas in a 30-year-old man, and discuss the relationship between these two autosomal dominant syndromes.

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

    Basal cell carcinoma is the most common malignant tumor of the skin, and it develops most frequently on the areas of the body that make its treatment and care extremely difficult, especially in cases of neglecting or aggressive growth and invasion. Both typical mild cases as well as locally aggressive tumor types do not tend to metastasize, and it has been postulated that they should share some common biological and morphological features that might explain this behavior. In this study, we have utilized a high-resolution three-dimensional reconstruction technique on pathological samples from 15 cases of common aggressive (fibrosing and adenoid types) and mild (superficial type) basal cell carcinomas, and showed that all these types shared contact points and bridges with the underlying basal cell layer of the epidermis or with the outmost layer of the hair follicle. The connections found had in fact the highest number for fibrosing type (100%), compared to the superficial (85.71%) and adenoid (55%) types. The morphology of the connection bridges was also different, adjacent moderate to abundant inflammatory infiltrate seeming to lead to a loss of basaloid features in these areas. For the adenoid type, tumor islands seemed to be connected also to each other more strongly, forming a common "tumor lace", and while it has been showed that superficial and fibrosing types have higher recurrence risks, all together these data might iterate a connection between the number of bridging points and the biological and clinical manifestation of this skin tumor.

    Recently, reduced Nasal nitric oxide (nNO) nNO levels have been reported in children with adenoidal hypertrophy predisposing to chronic nasosinusal inflammation. Given the strict anatomic and physiopathologic link between the nasopharyngeal and middle ear compartments, and considering the high prevalence of otitis prone children among those affected with chronic adenoiditis, we designed a study aimed to test any possible difference in nNO levels between non-allergic children with and without recurrent acute otitis media (RAOM) associated with chronic adenoiditis. The study involved 54 children with RAOM (44.4% males; mean age= 7.5±3.5 years) and 51 children without RAOM (47.4% males; mean age= 7.0±3.8 years). nNO levels were significantly reduced in children with RAOM compared to children without RAOM (676.9±250.7 ppb vs 831.8±320.4 ppb, respectively; p= 0.02). Our results could be related to reduced NO production by the ciliated paranasal, nasopharyngeal and middle ear epithelium and the impaired sinusal ostial and Eustachian tube patency due to chronic inflammation, and seem to confirm the involvement of NO pathway in recurrent upper airway infections related to impaired ciliated respiratory mucosa.

  8. High rates of detection of respiratory viruses in tonsillar tissues from children with chronic adenotonsillar disease.

    Directory of Open Access Journals (Sweden)

    Jose Luiz Proenca-Modena

    Full Text Available Chronic tonsillar diseases are an important health problem, leading to large numbers of surgical procedures worldwide. Little is known about pathogenesis of these diseases. In order to investigate the role of respiratory viruses in chronic adenotonsillar diseases, we developed a cross-sectional study to determine the rates of viral detections of common respiratory viruses detected by TaqMan real time PCR (qPCR in nasopharyngeal secretions, tonsillar tissues and peripheral blood from 121 children with chronic tonsillar diseases, without symptoms of acute respiratory infections. At least one respiratory virus was detected in 97.5% of patients. The viral co-infection rate was 69.5%. The most frequently detected viruses were human adenovirus in 47.1%, human enterovirus in 40.5%, human rhinovirus in 38%, human bocavirus in 29.8%, human metapneumovirus in 17.4% and human respiratory syncytial virus in 15.7%. Results of qPCR varied widely between sample sites: human adenovirus, human bocavirus and human enterovirus were predominantly detected in tissues, while human rhinovirus was more frequently detected in secretions. Rates of virus detection were remarkably high in tonsil tissues: over 85% in adenoids and close to 70% in palatine tonsils. In addition, overall virus detection rates were higher in more hypertrophic than in smaller adenoids (p = 0.05, and in the particular case of human enteroviruses, they were detected more frequently (p = 0.05 in larger palatine tonsils than in smaller ones. While persistence/latency of DNA viruses in tonsillar tissues has been documented, such is not the case of RNA viruses. Respiratory viruses are highly prevalent in adenoids and palatine tonsils of patients with chronic tonsillar diseases, and persistence of these viruses in tonsils may stimulate chronic inflammation and play a role in the pathogenesis of these diseases.

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that has morphologic features similar to secretory carcinoma of the breast and that also harbors the same ETV6 translocation. Diffuse mammaglobin and S-100 immunoreactivity are used to differentiate MASC from its morphologic mimics, especially acinic cell carcinoma and adenocarcinoma, not otherwise specified. However, the combination of mammaglobin and S-100 immunoreactivity has not been well studied in other types of salivary gland carcinomas that may have focal areas reminiscent of MASC. Here we evaluated mammaglobin and S-100 immunoreactivity in 15 cases each of polymorphous low-grade adenocarcinoma, adenoid cystic carcinoma and mucoepidermoid carcinoma, and also in 2 cases of adenocarcinoma, not otherwise specified, and 1 mucinous adenocarcinoma. Cases with significant co-expression of mammaglobin and S-100 (moderate or strong immunoreactivity in >25% of tumor cells) were further analyzed by fluorescence in situ hybridization using the ETV6 (12p13) break-apart probe. Nine cases (60%) of polymorphous low-grade adenocarcinoma and two (13.3%) of adenoid cystic carcinoma met the criteria for significant co-expression of mammaglobin and S-100. All were negative for the ETV6 translocation by fluorescence in situ hybridization. Although mammaglobin and S-100 positivity was seen in the majority of polymorphous low-grade adenocarcinomas and a minority of adenoid cystic carcinomas, none were positive for the ETV6 translocation characteristic of MASC. This indicates a need for caution in the use of immunohistochemistry for diagnosing MASC, especially in the absence of cytogenetic confirmation.

Methods Retrospective analyse the clinical data of 180 patients with tonsil and adenoidal hypertrophy. Clinical treatment efficacy to resect tonsil and adenoidal was observed in all cases between the low-temperature plasma with nasal endoscopic and the traditional surgical treatment. Results During 6 months after operation, children with snore were significantly reduced in all cases, however, the difference between the nasal endoscopic group and the traditional surgical group was significant (P<0.05), and the similar result was shown in the efficacy of secretory otitis media (P<0.05). The nasal endoscopic group was significantly better. Conclusion The treatment to resect tonsil and adenoidal of children with snore by the low-temperature plasma with nasal endoscopic appears to produce good results, and it is worth of increasing clinic use.

    Crouzon syndrome is characterized by abnormal craniofacial growth due to craniosynostosis. Skull base may also be involved in the pattern of malformations. Grisel's syndrome, an inflammation-mediated atlanto-axial instability occurs rarely in children after adenoidectomy. We report a 9-year-old female Crouzon patient, without vertebral anomalies, who developed severe torticollis few days after adenoid curettage. A deformity of the skull base alone might have induced an irregular arrangement of the craniocervical junction elements, thus increasing the susceptibility to cervical spine complications.

    This review summarizes the mechanisms that control the activity of the c-Myb transcription factor in normal cells and tumors, and discusses how c-Myb plays a role in the regulation of the cell cycle. Oncogenic versions of c-Myb contribute to the development of leukemias and solid tumors such as adenoid cystic carcinoma, breast cancer and colon cancer. The activity and specificity of the c-Myb protein seems to be controlled through changes in protein-protein interactions, so understanding how it is regulated could lead to the development of novel therapeutic strategies.

    Salivary gland tumors generate considerable interest because of their heterogeneous and variable histology, grade of malignancy, and clinical behavior. Fine needle aspiration cytology (FNAC) is considered the first diagnostic modality for salivary neoplasms due to its ready availability and ease of performance. However it cannot always be relied upon in isolation, and should be used in conjunction with other investigations like incisional biopsy. We present two cases, which highlight the drawbacks of relying on FNAC alone, which resulted in misdiagnosis of adenoid cystic carcinoma as pleomorphic adenoma. PMID:25848154

    Full Text Available Pediatric obstructive sleep apnea (OSA is not always resolved or improved with adenotonsillectomy. Persistent or complex cases of pediatric OSA may be due to sites of obstruction in the airway other than the tonsils and adenoids. Identifying these areas in the past has been problematic, and therefore, therapy for OSA in children who have failed adenotonsillectomy has often been unsatisfactory. Sleep endoscopy is a technique that can enable the surgeon to determine the level of obstruction in a sleeping child with OSA. With this knowledge, site-specific surgical therapy for persistent and complex pediatric OSA may be possible.

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the variation in shape, size and area of the pharynx and adenoids, and to analyze the relationship between pharyngeal cavity and upper facial cranium which effected on morphology of those parts in Korean. Age changes and sex differences in those areas were comprised in this study. Materials included 272 lateral cephalograms, which were divided into 4 groups by age; (1) 7-year-old group consisted of 29 males and 30 females,(2) 12-year-old group consisted of 30 males and 30 females, (3) 17-year-old group consisted of 30 males and 40 females, (4) 20-year-old group consisted of 37 males and 46 females, In subjects each variable was measured and evaluated statistically introducing 17 reference points and 17 reference lines respectively. Conclusions from this study were as follows. 1. Linear measurements of the bony nasopharynx revealed that the depth and height were larger in male than those in female in 17 and 20-year-old groups. 2. Linear measurements of the upper facial cranium were larger in male than those in female in all age groups. 3. Angular measurements of the bony nasopharynx and upper facial cranium did not show, on an average, sex differences in each age group. 4. As regards area of the bony nasopharynx, it increased gradually with age in both sexes. And the area was greater in male than that in female in 17 and 20-year-old groups. 5. There were sex differences in area of the adenoids of which the area was larger in male than that in female in 17 and 20-year-old groups. And the area reached a peak at 17-year-old group in male and at 12-year-old group in female. 6. Area of the pharyngeal cavity increased gradually with age in both sexes, but no sex differences were noted in each age group. 7. Rate of area of the adenoids to that of the pharyngeal cavity decreased continually with age, and no sex differences were noted in all age groups. 8. In amounts and its differences of the growth, there were sex differences in the

    Childhood obesity is a common and significant public health problem all over the world. As a well-known fact obese children have an increased risk of obesity-associated comorbidities, including obstructive sleep apnea, diabetes, and cardiovascular disorders at an earlier age compared to their normal weight peers. They also have an increased risk of poor self-esteem, greater body dissatisfaction, and increased peer teasing that lead to a lower health-related quality of life. While the presence of adenoid hypertrophy and increased rate of obstructive sleep apnea frequently co-exists in majority of cases. We have limited knowledge about the effect of adenotonsillar hypertrophy on development of childhood obesity. In this study, we aimed to investigate the association between obesity, presence of adenotonsillar hypertrophy and the quality of life parameters in obese children as measured by the OSA-18 quality of life questionnaire. Fifty obese children aged between 3 and 18 years and 50 age- and gender-matched otherwise children were enrolled to the study. All subjects were routinely examined by the otolaryngologist before enrollment. The size of adenoid hypertrophy was measured using lateral cephalometric radiographs. The tonsils were also graded using the schema recommended by Brodsky et al. We used OSA-18 questionnaires to evaluate the subjects' quality of life issues. We found, 34 % of obese group had tonsillar hypertrophy while the rate was 6 % in control group. Similarly 16 % of obese group had tonsillar hypertrophy compared to only 4 % in non-obese group. It was also noted that total OSA-18 scores of obese group were significantly higher than those of non-obese group. In subgroup analysis of obese group, total OSA-18 score of obese subjects with either adenoid and/or tonsillar hypertrophy was significantly higher than that of obese subjects without adenoid or tonsillar hypertrophy. As the related literature suggests that the impact of adenotonsillar size on OSA

    Full Text Available Nasal obstruction is a common symptom. Usually it is due to the presence of enlarged inferior turbinates, adenoid hypertrophy or pathological nasal mass. The most commonly encountered is nasal polyp. The presence of a physically obstructing mass causing the symptom can be easily explained. However, there are some patients with nasal polyp who do not have the feeling of congestion or nasal obstruction. There might be due to the mechanoreceptor that is free from stimulation despite the presence of the polyp. This review was made in the process of understanding the presence and type of mechanoreceptors in animal as well human nose.

    Direct visualization of the nasopharynx gives the otolaryngologist a unique advantage for addressing difficult nasopharyngeal anatomy. One common situation is being consulted to assist when the blind placement of a nasogastric tube has failed. A novel technique for managing a patient with a nasogastric tube embedded in the adenoid remnant is described with illustrations. The atraumatic method is easily employed by a resident armed with a portable nasolaryngoscope and plain suture. By using a repeated pull-through technique, the nasogastric tube can be guided past difficult nasopharyngeal anatomy and into a position from where it can be advanced into the patient's esophagus.

    Full Text Available Aims: Otitis media with effusion (OME is a common cause of hearing and speech impairment in children. The correlation of the clinical, audiological, radiological, and intraoperative findings was carried out so as to make a protocol for early diagnosis and management of OME. It will help prevent the more serious sequelae of OME such as tympanosclerosis, chronic adhesive otitis media, and even chronic suppurative otitis media. Methods: 300 clinically diagnosed patients of OME were studied prospectively. Thereafter, patients underwent impedance audiometry, pure tone audiometry, and X-ray soft tissue nasopharynx for adenoids. The patients were given adequate medical treatment for 3 to 6 months, and the patients who did not respond to the treatment were subjected to adenoidectomy with ear examination under magnification and myringotomy with or without grommet insertion. Results: The mean age at presentation was 5.96 years. Only 32% patients gave a history of hearing loss. About 90% patients had mouth breathing, followed by snoring (84%. About 79% ears had abnormal tympanic membrane appearance and mobility; 65.5% had an abnormality on impedance audiometry; and 69.75% had an air condition threshold level of >20 dB. About 78% patients had either Grade III or Grade IV Adenoid hypertrophy. Adenoidectomy was done in all 300 patients with myringotomy in 472 ears. Grommets were inserted in 365 ears. There was a significant reduction in mean air conduction threshold with an improvement of 8.0 dB and 7.5 dB in right and left ears, respectively at 2 months postoperatively. At 6 th month postoperative, the average improvement from baseline dropped to 6.0 dB in right ear and 5.5 dB in the left ear. Conclusion: OME is the most frequent causes of silent hearing impairment in young children which needs a close vigil. All suspected children (on clinical and otoscopic findings must be subjected to impedance audiometry and X-ray soft tissue nasopharynx for adenoids

    Full Text Available Alterations in the functions of the facial muscle can establish changes in facial skeleton and in the development of occlusion. The effect of mouth breathing on the facial morphology is probably greatest during the growth period. Removal of nasal obstruction, adenoids, and tonsils have not given beneficial results in the reversion of the habit unless intercepted with various muscle exercises. Hence, this study was conducted to ultrasonographically evaluate the effectiveness of circumoral muscle exercises in the developing dentofacial morphology in adenotonsillectomized children.

    Among malignant neoplasms of the sino-nasal tract, tumors of the nasal vault have special features: their higher incidence in woodworkers, their frequent local recurrence and invasiveness in the skull base. Histologically too, they are peculiar by the predominance of the glandular tumors, of colonic or enteric type especially. Microscopic examination allows histological grading of these adenocarcinoma. Squamous carcinoma and adenoid cystic carcinoma are less frequent than in other parts of the sinonasal tract. Rare other tumors, often undifferentiated, can be diagnosed by immuno-staining as esthesioneuroblastomas, malignant melanomas, neuro-endocrine carcinomas, malignant lymphomas or sarcomas. A retrospective study of 147 patients yielded similar data.

    Full Text Available Polymorphous low-grade adenocarcinomas (PLGA are distinctive salivary gland neoplasms, with an almost exclusive propensity to arise from the minor salivary glands. PLGA frequently manifests as an asymptomatic, slow-growing mass within the oral cavity, which must be separated from adenoid cystic carcinoma and benign mixed tumor for therapeutic and prognostic considerations. We report a case of a 67-year-old male, who presented with a long-standing mass in the palate. This lesion was diagnosed as PLGA based on histopathological findings, which was further confirmed by the immunohistochemical marker.

    Submucous cleft palate refers to a situation where the soft palate is largely composed of mucosa with little or no muscle. The defect is often not obvious on inspection of the mouth and pharynx. There is considerable clinical variation, with speech ranging from normal or minimal nasality to severe nasality and defective articulation. Many patients who have latent submucous cleft palate have the condition unmasked by an adenoidectomy because the adenoid pad had served as a compensatory factor in effecting palatopharyngeal closure. All physicians who perform tonsillectomy and adenoidectomy should be aware of the signs and symptoms which may suggest the diagnosis. ImagesFIG. 2 PMID:4758872

    Tumors of the lacrimal gland comprise a wide spectrum, of which the most common demonstrate epithelial and lymphoid differentiation. The diagnosis of lacrimal gland tumors depends primarily on histological evaluation, as do the choice of treatment and prognosis. For some lacrimal gland neoplasms......, such as adenoid cystic carcinoma, the outlook is grave. Optimal treatment for several lacrimal gland tumors is also a matter of controversy. However, recent progress has been made in the molecular and genetic understanding of tumorigenesis for such lesions. This article presents an overview of the histopathology...... of lacrimal gland tumors, together with their epidemiological features, clinical characteristics, and treatment strategies....

    Sleep is important for children pertaining to their physical and mental growth. Obstructive sleep apnea syndrome (OSAS) in children has been shown to have different effects as compared to OSAS in adults, including deficits in cognition and neuropsychological functions, hyperactivity, ADHD, behavior problems, aggressive behavior, learning problems and nocturnal enuresis. Hypertrophy of the adenoids and tonsils is a major cause of OSAS in children; therefore, adenotonsillectomy may decrease the effects of OSAS pertaining to physical and mental growth. It is important to accurately diagnose and appropriately treat OSAS in children to prevent OSAS in their adulthood. PMID:27115764

    Full Text Available Aim. To evaluate the prevalence and possible etiological factors associated with molar incisor hypomineralization (MIH among a group of children in Jeddah, Saudi Arabia. Methods. A group of 8-12-year-old children were recruited (n=267  from the Pediatric Dental Clinics at the Faculty of Dentistry, King Abdulaziz University. Children had at least one first permanent molar (FPM, erupted or partially erupted. Demographic information, children’s medical history, and pregnancy-related data were obtained. The crowns of the FPM and permanent incisors were examined for demarcated opacities, posteruptive breakdown (PEB, atypical restorations, and extracted FPMs. Children were considered to have MIH if one or more FPM with or without involvement of incisors met the diagnostic criteria. Results. MIH showed a prevalence of 8.6%. Demarcated opacities were the most common form. Maxillary central incisors were more affected than mandibular (P=0.01. The condition was more prevalent in children with history of illnesses during the first four years of life including tonsillitis (P=0.001, adenoiditis (P=0.001, asthma (P=0.001, fever (P=0.014, and antibiotics intake (P=0.001. Conclusions. The prevalence of MIH is significantly associated with childhood illnesses during the first four years of life including asthma, adenoid infections, tonsillitis, fever, and antibiotics intake.

  13. Primary tumors of the trachea. Results of radiation therapy

    International Nuclear Information System (INIS)

    From 1959 to 1986, 24 patients with primary malignant tumors of the trachea received radiotherapy as all or part of treatment. Common presentations included respiratory symptoms in 20 patients and hemoptysis in 15. Thirteen patients had squamous carcinomas with undifferentiated and adenoid cystic cancers in five and four patients, respectively. Overall actuarial survival was 45% at 1 year, 25% at 5 years, and 13% at 10 years. Survival was significantly correlated to histologic type (adenoid cystic versus squamous, P less than 0.03), but not to tumor extent or to patient age or sex. Local control was attained in 10 of 24 patients overall and was more frequent for patients with tumors localized to the trachea and for patients who were treated with combined surgery and radiotherapy. For the 18 patients treated with radiotherapy alone, complete response (CR) was seen to be significantly (P less than 0.001) related to dose: six of seven (86%) patients receiving greater than or equal to 6000 cGy attained CR versus one of 11 (9%) receiving less than 6000 cGy. Three patients developed complications related to radiotherapy. Radiotherapy can provide durable local control of localized tracheal tumors and should be considered for medically inoperable patients with localized tumors and for patients with high risk of recurrence after resection

    To date, the underlying genomic changes in benign and malignant tumors of salivary-gland and paranasal-sinus origin are poorly understood. This is due in part to the low incidence of these tumors and the enormous histological variety of tumors within this head and neck region. We examined 58 of these tumors (14 adenoid cystic carcinomas, 9 adenocarcinomas, 5 cylindrical carcinomas, 11 pleomorphic adenomas, and 19 inverted papillomas) by dual fluorescence in situ hybridization (FISH) with centromere-specific probes on six chromosomes (3, 7, 9, 11, 17, and 18) for numerical changes. In adenoid cystic carcinomas, monosomy of chromosome 17 and polysomy of chromosomes 3, 9 and 11 were most frequently encountered. In adenocarcinomas, monosomy of chromosome 17 and polysomy of chromosomes 7 and 11 were most frequent. In cylindrical cell carcinomas, polysomy of chromosomes 7, 9, 11 and 17 was present in the majority of tumors. Disomy is rare, even in benign tumors. Polysomy is more frequent in malignant tumors than in benign. Tetrasomy is found almost only in malignant tumors. In summary, the occurrence of polysomy might reflect a step towards malignancy in tumors of the salivary glands and paranasal mucosa. Polysomy of chromosome 11 could be defined as typical for all investigated histological types of malignant tumor in this region of the head and neck. PMID:16211271

    The purpose of this study was to identify and compare the results of the findings from speech-language pathology evaluations for orofacial function including tongue and lip rest postures, tonus, articulation and speech, voice and language, chewing, and deglutition in children who had a history of mouth breathing. The diagnoses for mouth breathing included: allergic rhinitis, adenoidal hypertrophy, allergic rhinitis with adenoidal hypertrophy; and/or functional mouth breathing. This study was conducted with on 414 subjects of both genders, from 2 to 16-years old. A team consisting of 3 speech-language pathologists, 1 pediatrician, 1 allergist, and 1 otolaryngologist, evaluated the patients. Multidisciplinary clinical examinations were carried out (complete blood counting, X-rays, nasofibroscopy, audiometry). The two most commonly found etiologies were allergic rhinitis, followed by functional mouth breathing. Of the 414 patients in the study, 346 received a speech-language pathology evaluation. The most prevalent finding in this group of 346 subjects was the presence of orofacial myofunctional disorders. The most frequently orofacial myofunctional disorder identified in these subjects who also presented mouth breathing included: habitual open lips rest posture, low and forward tongue rest posture and lack of adequate muscle tone. There were also no statistically significant relationships identified between etiology and speech-language diagnosis. Therefore, the specific type of etiology of mouth breathing does not appear to contribute to the presence, type, or number of speech-language findings which may result from mouth breathing behavior.

    Helicobacter pylori (H. pylori) is one of the frequently encountered micro-organisms in the aerodigestive tract. Although infections caused by H. pylori are this common, the exact mode of transmission has not been fully understood yet. Oral-oral, fecal-oral and gastrointestinal-oral routes are the possible modes of transmission. This infection is usually acquired in childhood and may persist for the whole life of the patient. However, about 80% of the infected humans are asymptomatic. Human stomach was considered to be the only reservoir of H. pylori until bacteria were discovered in human dental plaque, in oral lesions, in saliva, in tonsil and adenoid tissue. It is suggested that H. pylori enters the nasopharyngeal cavity by gastroesophageal reflux and colonize in the dental plaques, adenoid tissues and tonsils. From these localizations, the bacteria ascend to the middle ear and to the paranasal sinuses directly or by the reflux again and may trigger some diseases, including otitis, sinusitis, phyrangitis, laryngitis and glossitis. But still, the exact mechanism remains unclear. PMID:18942285

    Full Text Available Objectives. Detection of extraesophageal reflux (EER in children with chronic otitis media with effusion (OME using three different diagnostic methods. Methods. Children between 1 and 7 years with OME who underwent adenoidectomy and myringotomy with insertion of a ventilation tube were included in this prospective study. EER was detected using three methods: oropharyngeal pH was monitored for 24 hours using the Restech system; detection of pepsin in middle ear fluid obtained during myringotomy was done using Peptest, and detection of pepsin in an adenoid specimen was done immunohistochemically. Results. Altogether 21 children were included in the study. Pathological oropharyngeal pH was confirmed in 13/21 (61.9% children. Pepsin in the middle ear fluid was present in 5/21 (23.8% children; these 5 patients were diagnosed with the most severe EER established through monitoring of oropharyngeal pH. No specimen of adenoids tested was positive for pepsin upon immunohistochemical examination. Conclusions. Diagnosis of EER in patients with OME using Restech is sensitive but less specific when compared to the detection of pepsin in middle ear fluid using Peptest. Pepsin in the middle ear was consistently present in patients with RYAN score above 200, and these patients in particular could potentially profit from antireflux therapy.

    Patients who undergo segmental or hemi-mandibulectomy suffer from various postoperative problems in esthetics and function. The solution to such problem is providing a mandibular guidance appliance to correct mandibular deviation to resected side due to loss of muscle action on the affected side. This article describes the treatment of a female patient who underwent segmental mandibulectomy on right side secondary to adenoid cystic carcinoma of the base of tongue. An acrylic guidance appliance was constructed to help control the mandibular deviation and co-ordinate masticatory movements. The prosthesis was worn continuously by the patient for 1 month which corrected the occlusion on the left side. To compensate for the open-bite caused due to rotation of mandible following partial mandibulectomy, an overlay removable partial denture was given. The patient was satisfied with the improvement in esthetics and mastication.

    A retrospective study was performed on 47 patients with primary malignant neoplasms of the parotid gland treated in our department between 1982 and 1999. Most of the patients were male and over age 40, and 23 patients were of stage IV in clinical classification. The most frequently observed histological type was adenocarcinoma (12 patients), and the next was adenoid cystic carcinoma (11 patients). A radical parotidectomy with postoperative radiation therapy was administered in 38 patients, and palliative treatment in 9. The global survival rate was 74.1% at 5 years, and 89.4% in the patients treated with the radical procedure. Radical operative treatment and subsequent over 50-Gy of irradiation supposed to be the important factor to improve the prognosis. (author)

    Basal cell adenoma of the salivary glands is an uncommon type of monomorphous adenoma. Its most frequent location is the parotid gland. It usually appears as a firm and mobile slow-growing mass. Histologically, isomorphic cells in nests and interlaced trabecules with a prominent basal membrane are observed. It is also characterized by the presence of a slack and hyaline stroma and the absence of myxoid or condroid stroma. In contrast to pleomorphic adenoma, it tends to be multiple and its recurrence rate after surgical excision is high. Due to prognostic implications, differential diagnosis with basal cell adenocarcinoma, adenoid cystic carcinoma and basaloid squamous cell carcinoma is mandatory. We describe a case of basal cell adenoma of the parotid gland. We also review the literature and discuss the diagnosis and management of this rare entity.

    Anterior mediastinal tracheostomy (AMT) is performed to establish an airway after resection of advanced tumors in the cervicothoracic region. We report a case of successful placement of a covered retrievable self-expandable nitinol stent for a stoma stricture that developed after AMT in a patient with adenoid cystic carcinoma of the trachea. Two stent placements and removals, at two and three months after their initial placement, were performed due to loosening of the stents. Although we did not achieve long-term results as the patient died of massive hemorrhage, the stent placement was both feasible and safe, thus suggesting that temporary stent placement may be a valuable option for treating stoma stricture occurring after AMT.

    Full Text Available The lung tumors with carinal involvement are frequently managed with tracheal sleeve pneumonectomy and tracheobronchial anastomosis without use of cardiopulmonary bypass (CPB. Various modes of ventilation have been described during tracheal resection and anastomosis. Use of CPB during this period allows the procedure to be conducted in a more controlled way. We performed tracheal sleeve pneumonectomy for adenoid cystic carcinoma of left lung involving carina. The surgery was performed in two stages. In the first stage, left pneumonectomy was performed and in the second stage after 48 h, tracheobronchial resection and anastomosis was performed under CPB. Second stage was delayed to avoid excessive bleeding (due to heparinization from the extensive vascular raw area left after pneumonectomy. Meticulous peri-operative planning and optimal post-operative care helped in successful management of a complex case, which is associated with high morbidity and mortality.

    A powder preparation of the oral probiotic Streptococcus salivarius K12 has been given to 19 young otitis media-prone children following a 3-day course of amoxicillin administered as a preliminary to ventilation tube placement. In two subjects, the use of strain K12 appeared to effect the expansion of an indigenous population of inhibitory S. salivarius. In other children, strain K12 colonisation extended beyond the oral cavity to also include the nasopharynx or adenoid tissue. The relatively low proportion (33%) of subjects that colonised was attributed to failure of the amoxicillin pre-treatment to sufficiently reduce the indigenous S. salivarius populations prior to dosing with strain K12 powder.

    Full Text Available Bacterial biofilms play a role in upper respiratory tract diseases, including acute and chronic middle ear diseases, and are involved in chronic infections and resistance to antibiotic treatment. In particular, the nasopharynx and the surrounding tissues act as important reservoirs of resistant bacterial biofilms, which have been detected in biopsies taken from adenoid and/or middle ear mucosa of children with chronic middle ear effusion. Here we describe the management of a child with congenital immunodeficiency and a chronic middle ear effusion, resistant to traditional medical treatment and presumably due to nasopharyngeal colonization by bacterial biofilms, which has been successfully treated by means of medicated nasal douches delivering antibiotic and a biofilm-destroying compound.

    The most frequent malignant salivary gland tumours are the mucoepidermoid tumour, adenoid cystic carcinoma and adenocarcinoma. The major salivary glands and the minor glands of the mouth and upper respiratory tract may potentially develop any of these malignant lesions. Malignant lesions most frequently present as a palpable mass and tend to enlarge more rapidly than benign neoplasms. Pain, paresthesia, muscle paralysis and fixation to surrounding tissue are all ominous signs and symptoms. The only reliable means of differential diagnosis of these lesions is biopsy and histologic analysis. Therapy involves surgery or a combination of surgery and radiation therapy. The ultimate prognosis is governed by the intrinsic biologic behaviour of the neoplasms, the extent of disease and adequate clinical therapy.

    Satheesh B. Haralur

    2013-01-01

    Full Text Available The loss of anterior teeth has serious functional, esthetic disabilities, in addition to compromising the patients' quality of life. Various etiologies can be attributed to the anterior tooth loss, including trauma, caries, and periodontal diseases. The chronic mouth breathing due to nasal adenoids is known to enhance the gingival and periodontal diseases. The dental literature proves the association of nasal breathing, tongue thrusting, and anterior open bite. Arch shape and tooth position are primarily determined by the equilibrium of the forces from tongue and perioral musculature. Increased force from tongue musculature in the tongue thrusting patient leads to flaring of anterior teeth, making them susceptible for periodontal and traumatic tooth loss. Replacement of the anterior teeth in this patient will also help in restoration of anterior guidance, which is critical for the health of temporomandibular joint, posterior teeth, and musculature.

    2007-01-01

    Tonsillectomy and adenoidectomy, 2 of the most common childhood surgeries, are performed for a number of indications, the most common being airway obstruction caused by adenotonsillar hypertrophy. Other indications for tonsillectomy include recurrent pharyngotonsillitis, streptococcal carriage, recurrent peritonsillar abscess, halitosis, and presumed neoplasia. Although adenotonsillar surgery is a safe and effective technique for treating disease and obstruction, parents remain concerned about postoperative morbidity, for which the potential is much greater after tonsillectomy than adenoidectomy. Postoperative pain and hemorrhage are 2 unpleasant side effects that can prolong postoperative recovery. Surgeons use a variety of surgical techniques to remove the tonsils and adenoids. When compared with older techniques, such as cold steel dissection and monopolar electrocautery, a new technique named Coblation that uses lower temperatures than electrocautery to remove tonsil tissue and achieve hemostasis, has been shown to reduce pain and decrease postoperative narcotic use, leading to shorter recovery times and a quicker return to normal in children.

    @@ Adenomatoid tumors are the most commonly located in male and female genital tracts, but they are rarely found in extragenital locations, especially in adrenal glands.~1 These tumors are considered as benign neoplasms of mesothelial derivation, and pathologically show glandular tubules lined by epitheloid cells with intervening trabeculae with a characteristic mixture of adenoidal, angiomatoid, cystic and solid patterns, in addition to focal calcifications and signet-ring like cells frequently.~2 Because of the lack of radiological specificity, there is usually a wide range of differential diagnoses. Radiologically adrenal adenomatoid tumors are commonly solid but rarely may be extensively cystic.~1 We present a case of a giant cystic adenomatoid tumor of the adrenal gland.

    Based on 15 years of experience with neutron therapy at the former facility at Munich research reactor FRM, fast neutron therapy with fission neutrons of FRM II is performed at the new facility MedApp since June 2007. General indications are superficially located tumors with insufficient response to conventional radiotherapy. Until August 2009, 58 patients were treated, 25% of them with curative intention (adenoid cystic carcinoma of major salivary glands, malignant melanoma, sarcoma). The most frequent palliative indications were breast wall recurrences of breast cancer and skin or lymph node recurrences of squamous cell carcinomas, resulting in response rates of 84% and 42%, respectively. Short treatment times of fast neutron therapy (3-5 fractions in 2-3 weeks) are advantageous in palliative treatment strategies.

    Necrotizing sialometaplasia (NS) was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory process involving minor salivary glands of the hard palate. Before that recognition, many patients with this condition had been improperly treated because of its clinical and histologic resemblance to malignancy such as mucoepidermoid carcinoma and squamous cell carcinoma. We report two cases of necrotizing sialometaplasia. One case involved a 58-year-old male who had an ulcerative palatal lesion exposing underlying bone which has the typical features of the above mentioned condition. Another case involved a 59-year-old male who developed a necrotizing sialometaplasia in association with a dome-shaped palatal swelling which was proves as an adenoid cystic carcinoma after operation biopsy.

    Palatal tumors commonly arise from the minor salivary glands, and benign tumors account for approximately half of all minor salivary gland tumors. Minor salivary gland tumors have an affinity for the posterior hard palate and soft palate and virtually never arise in the midline, probably because of the distribution of palatal salivary glands. The majority of benign salivary gland tumors of the palate are pleomorphic adenomas, while the most common malignant salivary gland tumor is adenoid cystic carcinoma, followed by mucoepidermoid carcinoma, adenocarcinoma, and polymorphous low-grade adenocarcinoma. Epithelial tumors frequently arise from the soft palate. The majority of benign epithelial tumors of the palate are papillomas, while most malignant epithelial tumors are squamous cell carcinomas. Various types of mesenchymal tumors, including fibromas, lipomas, schwannomas, neurofibromas, hemangiomas, and lymphangiomas, also involve the palate. This article describes the CT and MR findings of benign and malignant palatal tumors.

    Monensin at 60, 80, or 100 ppm in feed reduced mortality and lesion scores while protecting against weight loss of turkeys infected with the major pathogenic species: Eimeria adenoides, E. meleagrimitis, and E. gallopavonis. With single and mixed infections in battery-cage experiments, the death rate of unmedicated turkey poults was 33-75%. Weight gains were significantly (P is less than or equal to 0.05) better with 100 ppm monensin than 60 ppm, as were also lesion scores. Under floor-pen conditions there were no significant differences among monensin treatments. Moisture content of the litter was significantly lower in all monensin-medicated pens (40%, compared with 52% moisture in pens of unmedicated controls).

    The facial patterns of 29 children under the age of 15 years with tonsil and/or adenoid and sleep disorder problems was analysed. The lateral-cephalograms of these patients was digitized in a zero-based computer program using Ricketts analysis to examine facial patterns. Results of the analysis were compared with the mean of the control group, n = 41 (9-year-old Japanese children). There were significant differences (P < 0.01-0.001) between the patient group and the control group when comparing the facial axis, lower facial height, mandibular arc, total facial height, and McNamara-Pogonion. The facial pattern of children with sleep breathing disorders was discovered to be the dolico facial pattern.

Among large cell undifferentiated carcinomas, lymphoepithelial carcinomas have to be distinguished, the latter of which are endemic in the Arctic regions and southern China where virtually all cases...... of these tumors are associated with the Epstein-Barr virus (EBV). Association with EBV may also be observed in sporadic cases, and detection of EBV gene products may aid their diagnosis. Immunohistology may be employed to resolve the differential diagnosis of undifferentiated salivary gland carcinomas, comprising...... malignant lymphomas, amelanotic melanomas, Merkel cell carcinomas, and adenoid cystic carcinomas, in particular in small biopsy materials. Because of the rarity of undifferentiated salivary gland carcinomas, the differential diagnosis should always include metastases of undifferentiated carcinomas arising...

Four had adenoid cystic carcinoma and two a mucoepidermoid carcinoma. All patients were male...

  8. Retrievable Airway Stent Placement for Stoma Stricture after Anterior Mediastinal Tracheostomy: Case Report

    International Nuclear Information System (INIS)

    Anterior mediastinal tracheostomy (AMT) is performed to establish an airway after resection of advanced tumors in the cervicothoracic region. We report a case of successful placement of a covered retrievable self-expandable nitinol stent for a stoma stricture that developed after AMT in a patient with adenoid cystic carcinoma of the trachea. Two stent placements and removals, at two and three months after their initial placement, were performed due to loosening of the stents. Although we did not achieve long-term results as the patient died of massive hemorrhage, the stent placement was both feasible and safe, thus suggesting that temporary stent placement may be a valuable option for treating stoma stricture occurring after AMT.

    HSV-tk/ACV induced and killed human adenoid cystic carcinoma cell (ACC-M) in vivo and in vitro, which were observed through optical imaging and green fluorescence protein (GFP) tagging technique. ACC-M was transfected with TK-GFP, and the single clone cell ACC-M-TK-GFP was selected by G418. With fluorescent stereomicroscope, whole-body fluorescent imaging system and fluorescent microscope, we could observe ACV treated ACC-M-TK-GFP cells in cell level and nude mice. The therapies of tumor were visualized clearly with optical imaging. This study proves that optical imaging is a very good approach for studying the effect of HSV-tk/ACV on the ACC-M tumor cells and decreasing the amount of vessel about tumors cell. Optical imaging will become a visual groundwork for monitoring tumor growth and evaluating in vivo curative effect of antitumor drugs.

    Full Text Available The incidence of multiple primary malignant neoplasms increases with age, reflecting an increase in overall cancer risk in older patients. Cases of two or more concurrent primary cancers are still rare, although its incidence is increasing. Here, we report the case of a 41-years female who was referred to our institution with synchronous papillary carcinoma of thyroid and Adenoid cystic carcinoma of submandibular gland. The case is being presented to emphasize that the clinicians should keep in mind that the appearance of another tumour in a patient suffering from cancer could be either a synchronous or a metachronous or a metastatic lesion.

    Full Text Available Abstract Background Tracheal malignancies are usual victim of delay in diagnosis by virtue of their symptoms resembling asthma. Sometimes delayed diagnosis may lead to almost total airway obstruction. For difficult airways, not leaving any possibility of manipulation into neck region or endoscopic intervention, femorofemoral cardiopulmonary bypass can be a promising approach. Case Presentation We are presenting a case of tracheal adenoid cystic carcinoma (cylindroma occupying about 90% of the tracheal lumen. It was successfully managed by surgical excision of mass by sternotomy and tracheotomy under femorofemoral cardiopulmonary bypass (CPB. Conclusion Any patient with recurrent respiratory symptoms should be evaluated by radiological and endoscopic means earlier to avoid delay in diagnosis of such conditions. Femorofemoral cardiopulmonary bypass is a relatively safe way of managing certain airway obstructions.

    Hyaluronic acid (HA) treatment has been successfully performed in patients with recurrent upper airway infections or rhinitis. The aim of this study was to assess the efficacy and safety of the topical nasal administration of an HA-based compound by investigating its effects in children with recurrent or chronic middle ear inflammations and chronic adenoiditis. A prospective, single-blind, 1:1 randomised controlled study was performed to compare otoscopy, tympanometry and pure-tone audiometry in children which received the daily topical administration of normal 0.9% sodium chloride saline solution (control group) or 9 mg of sodium hyaluronate in 3 mL of a 0.9% sodium saline solution. The final analysis was based on 116 children (49.1% boys; mean age, 62.9 ± 17.9 months): 58 in the control group and 58 in the study group. At the end of follow-up, the prevalence of patients with impaired otoscopy was significantly lower in the study group (P value = 0.024) compared to baseline but not in the control group. In comparison with baseline, the prevalence of patients with impaired tympanometry at the end of the follow-up period was significantly lower in the study group (P value = 0.047) but not in the control group. The reduction in the prevalence of patients with conductive hearing loss (CHL) (P value = 0.008) and those with moderate CHL (P value = 0.048) was significant in the study group, but not in the control group. The mean auditory threshold had also significantly improved by the end of treatment in the study group (P value = 0.004) but not in the control group. Our findings confirm the safety of intermittent treatment with a topical nasal sodium hyaluronate solution and are the first to document its beneficial effect on clinical and audiological outcomes in children with recurrent or chronic middle ear inflammations associated with chronic adenoiditis.

    Prominin-1 (CD133) is physiologically expressed at the apical membranes of secretory (serous and mucous) and duct cells of major salivary glands. We investigated its expression in various human salivary gland lesions using two distinct anti-prominin-1 monoclonal antibodies (80B258 and AC133) applied on paraffin-embedded sections and characterized its occurrence in saliva. The 80B258 epitope was extensively expressed in adenoid cystic carcinoma, in lesser extent in acinic cell carcinoma and pleomorphic adenoma, and rarely in mucoepidermoid carcinoma. The 80B258 immunoreactivity was predominately detected at the apical membrane of tumor cells showing acinar or intercalated duct cell differentiation, which lined duct- or cyst-like structures, and in luminal secretions. It was observed on the whole cell membrane in non-luminal structures present in the vicinity of thin-walled blood vessels and hemorrhagic areas in adenoid cystic carcinoma. Of note, AC133 labeled only a subset of 80B258-positive structures. In peritumoral salivary gland tissues as well as in obstructive sialadenitis, an up-regulation of prominin-1 (both 80B258 and AC133 immunoreactivities) was observed in intercalated duct cells. In most tissues, prominin-1 was partially co-expressed with two cancer markers: carcinoembryonic antigen (CEA) and mucin-1 (MUC1). Differential centrifugation of saliva followed by immunoblotting indicated that all three markers were released in association with small membrane vesicles. Immuno-isolated prominin-1-positive vesicles contained CEA and MUC1, but also exosome-related proteins CD63, flotillin-1, flotillin-2 and the adaptor protein syntenin-1. The latter protein was shown to interact with prominin-1 as demonstrated by its co-immunoisolation. A fraction of saliva-associated prominin-1 appeared to be ubiquitinated. Collectively, our findings bring new insights into the biochemistry and trafficking of prominin-1 as well as its immunohistochemical profile in certain types

  17. MRI analysis on soft tissue around upper airway in obese adolescent patients with obstructive sleep apnea syndrome

    International Nuclear Information System (INIS)

    Objective: To investigate the correlation of soft tissue structure of upper airway with the pathogenesis of obstructive sleep apnea syndrome (OSAS) in adolescents age group by analyzing magnetic resonance imaging (MRI) of upper airway. Methods: The subjects were divided into obese OSAS, obese controls and normal weight controls groups according to the results from polysomnography and body mass index measurements; Upper airway was scanned by MRI sagittally and axially; upper airway at all levels and soft tissue was analyzed by Amira Medical image analysis system. Results: Tongue volumes in obese OSAS and obese controls were significantly greater than that in normal weight controls (P<0.05); tonsil and adenoid volumes in obese OSAS were significantly higher than those in two control groups (P<0.05 or P<0.001), but no significant difference was found between two control groups. The volumes of lateral pharyngeal wall in obese OSAS were higher than those in obese controls and normal weight controls (P<0.05 or P<0.001), and they were higher in obese controls compared with normal weight controls (P<0.05). In obese OSAS group, positive correlations were found between volumes of lateral pharyngeal wall and apnea/hypopnea index (AHI) (r=0.879, P<0.01), as well volumes of tonsils and AHI (r=0.824, P<0.01). Conclusion: Obesity can increase the soft tissue volumes around upper airway, there by increase the upper airway obstruction; lateral pharyngeal wall and adenoid volumes play major roles in evaluating the severity of OSAS in adolescents.

    Nocturnal enuresis is defined as intermittent urinary incontinence during sleep that occurs at least twice a week for three consecutive months. There is no unifying etiology for nocturnal enuresis in the pediatric population and the disorder is likely to be multifactorial. We aimed to investigate the relationship between primary nocturnal enuresis, allergic rhinitis, and related complications in a paediatric case series from a single Center. We retrospectively reviewed and prospectively followed-up at our Institution (i) 32 children (14 females, 18 males; mean age 6.31±1.21 yrs) affected by allergic rhinitis with adenoidal hypertrophygrade I-II (group A) and (ii) 27 children (11 females, 16 males; mean age 6.52±1.33 yrs) affected by allergic rhinitis with adenoidal hypertrophy grade III-IV (group B). Allergic rhinitis was diagnosed on the basis of (a) typical nasal symptoms due to atopic sensitization (e.g., rhinorrhea , itching, sneezing fits, and nasal congestion and obstruction) and (b) positive skin prick testing and/or increased level of total serum IgE. We identified discrepancies between group A and group B in terms of risk of primary nocturnal enuresis. In fact, only 1 child of group A (3.12%) reported uncomplicated primary nocturnal enuresis; conversely, 6 children of group B (22.22%) showed a history of uncomplicated primary nocturnal enuresis (p=0.040). There was no statistically significant difference between the two groups in terms of atopic sensitization and serum total IgE levels (p=0.43). Allergic rhinitis may potentially influence the onset and the natural history of nocturnal enuresis in some children. Children with allergic rhinitis and more severe respiratory manifestations, seem to be more prone to developing primary nocturnal enuresis, likely due to potential multi-factorial causes (e.g., sleep disorders, chronic phlogosis, immune deregulation).

    A few cases of death worldwide during GH treatment in pediatric patients with Prader-Willi syndrome (PWS) have been recently described. The evaluation of further cases is needed to better identify possible causal mechanism(s), as well as to suggest some additional guidelines for prevention. We report the death of 2 additional children with genetically confirmed PWS in the first months of GH therapy. Case 1: This 3.9-yr-old girl was born at 39 weeks gestation. Low GH response to two stimulation tests was observed. GH administration was started at the age of 3.5 yr (0.33 mg/kg per week), when the patient was at 130% of her ideal body weight (ibw). Hypertrophy of adenoids was previously demonstrated. Snoring and sleep apnea were present before GH treatment, and did not increase during therapy. Four months later she died at home suddenly in the morning. Case 2: This patient was a 6.3-yr-old boy. He was born at term after an uneventful pregnancy. At the age of 6 yr, his weight was at 144% of his ibw. He showed reduced GH secretion during provocation tests, and GH therapy was started (0.20 mg/kg per week). The previously reported nocturnal respiratory impairment had worsened after beginning GH administration. Tonsils and adenoids hypertrophy were noted. At the age of 6.3 yr he died at home in the morning following an acute crisis of apnea. These additional cases seem to confirm that some children with PWS may be at risk of sudden death at the beginning of GH therapy. PMID:16117198

  20. MRI study of the non-thyroid-related exophthalmos

    International Nuclear Information System (INIS)

    Objective: To investigate the manifestation and diagnostic value of MRI in the patients with non-thyroid-related exophthalmos. Methods: One hundred and sixty-eight patients with non-thyroid related exophthalmos confirmed by histopathology underwent MRI examination using 8-channel phased array head coil. Of 168 patients,165 underwent contrast-enhanced MRI. Results: Of the 168 cases,68 were hemangioma, 34 were lymphoma, 14 were pleomorphic adenoma of the lacrimal gland, 12 were inflammatory pseudotumor, 6 were adenoid cystic carcinoma of the lacrimal gland, 6 were Schwannoma, 5 were dermoid cyst, 5 were meningioma, 3 were solitary fibrous tumor, 2 were optic nerve glioma, 2 were embryonal rhabdomyosarcoma, 2 were lipoma, et al. Of the 165 enhanced cases,the MRI diagnosis was in accordance with surgical pathology findings in 111 cases (67.3%). The tumor was hemangioma in 65, lymphoma in 22, pleomorphic adenoma of the lacrimal gland in 10, inflammatory pseudotumor in 5, meningioma in 3, adenoid cystic carcinoma of the lacrimal gland in 3, optic nerve glioma in 1, Schwannoma in 1, and dermoid cyst in 1. Eleven cases simultaneously had dynamic contrast-enhanced (DCE) MRI, the MRI diagnosis was consistent with pathological findings in 10 cases,which included 7 hemangioma, 2 lymphoma, and 1 meningioma. The time-intensity curves of DCE-MRI showed persistent enhancement type, rapidly enhancing and rapid wash-out and plateau-shaped type, and rapidly enhancing and rapid wash-out, respectively. Three cases showed soft tissue mass on only plain MRI. Conclusions: The conventional orbital MRI can explore the causes of proptosis, which is helpful to determine the location and nature of the mass.Enhanced and DCE MRI can further observe blood supply of the lesions.

    2008-08-01

    Otitis media with effusion (OME) affects 28-38% of pre-school children, and it occurs due to the dysfunction of the auditory tube. Anatomical development of the auditory tube depends on the craniofacial growth and development. Deviations of normal craniofacial morphology and growth using cephalometric studies, may predict the evolution of otitis. Our goal in this paper is to determine if there are differences in craniofacial morphology between children with adenoid enlargement, with and without otitis media with effusion. This is a prospective study in which the sample consisted of 67 children (male and female) from 5 to 10 years old. All patients presented chronic upper airway obstruction due to tonsil and adenoid enlargement (>80% degree of obstruction). Thirty-three patients presented otitis media with effusion, for more than 3 months and 34 did not. The latter composed the control group. Standardized lateral head radiographs were obtained for all subjects. Radiographs were taken with patient positioned by a cephalostat and stayed with mandibles in centric occlusion and lips at rest. Radiographs were digitalized and specific landmarks were identified using a computer program Radiocef 2003, 5th edition. Measurements, angles and lines were taken of the basicranium, maxilla and mandible according to the modified Ricketts analysis. In addition, facial height and facial axis were determined. Children with otitis media with effusion present differences in the morphology of the face, regarding these measures: N-S (anterior cranial base length), N-ANS (upper facial height), ANS-PNS (size of the hard palate), Po-Or.N-Pog (facial depth), Ba-N.Ptm-Gn (facial axis), Go-Me (mandibular length) and Vaia--Vaip (inferior pharyngeal airway).

    2009-01-01

    Full Text Available Problem statement: Helicobacter pylori (H. pylori is a microaerophilic, gram negative bacillus, which can cause peptic ulcer and gastric cancer. Recurrent infection with this agent is considered as one of the reasons for failure of peptic ulcer treatment. Some studies have reported colonization of H. pylori in dental plaques, tonsils and adenoid tissues. Therefore oral cavity could be the source of H. pylori and it might be the reason for unsuccessful eradication. Approach: In this cross sectional study, 95 patients with the average age of 12.1±7.5 years undergoing adenotonsillectomy were chosen consecutively. Intra-operatively a 2 mm section of the tonsils were removed and investigated for H. pylori by Rapid Urease Test (RUT. Post-operatively the removed tonsils were stained by hematoxylin-eosin (H and E and Gimsa for direct investigation of H. pylori bacterium. Serum samples of the patients were also tested for the presence of H. pylori IgG antibody. Results: Overall 70 patients (73.7% had positive anti- H. pylori IgG antibody in their sera. The results of RUT on adeno-tonsils showed that 42.1% of the specimens were positive for H. pylori. In histology examination, 9 patients (9.5% were positive for the presence of bacterium. Conclusion: Based on our findings it seems that tonsils and adenoid tissues are the candidate places for the growth of H. pylori. Further studies about the role of tonsillar colonization of H. pylori in re-infection after treatment are recommended.

    Full Text Available PURPOSE: To present experience with high dose-rate endobronchial brachytherapy in the treatment of primary tracheal tumors. PATIENTS AND METHODS: Four patients with nonresected primary tracheal tumors are presented: 2 cases of squamous cell carcinoma of the trachea, 1 of recurrent adenoid cystic carcinoma, and 1 with recurrent plasmacytoma. All received brachytherapy, alone or as a boost for primary irradiation, in 3 or 4 fractions of 7.5 Gy, calculated at a depth of 1 cm. Follow-up was considered to start from the end of brachytherapy. RESULTS: Local control was achieved in all cases at the time of first bronchoscopic evaluation. Two patients with squamous cell carcinoma died at 6th and 33rd months after brachytherapy, respectively. The first had no evidence of disease, and the latter had local recurrence. The other 2 patients were alive after 64 and 110 months of follow-up, respectively, both with no evidence of disease. Tracheal stenosis developed in these 2 cases, 22 and 69 months after brachytherapy. Tracheal stent placement was needed only for the patient with an adenoid cystic carcinoma. CONCLUSIONS: Endobronchial high dose-rate brachytherapy may be used for tracheal tumors, even as a boost for external beam irradiation, or in recurrences. Local control in 3 out of 4 patients indicates that individual cases may benefit from the treatment. Long-term survival may also be expected, mainly for tumors with adenoid cystic histology.OBJETIVO: Apresentar a experiência do tratamento de 4 pacientes com tumores primários de traquéia, não operados, submetidos à braquiterapia endobrônquica de alta taxa de dose.

  9. Availability and quality of paraffin blocks identified in pathology archives: A multi-institutional study by the Shared Pathology Informatics Network (SPIN)

    International Nuclear Information System (INIS)

    Shared Pathology Informatics Network (SPIN) is a tissue resource initiative that utilizes clinical reports of the vast amount of paraffin-embedded tissues routinely stored by medical centers. SPIN has an informatics component (sending tissue-related queries to multiple institutions via the internet) and a service component (providing histopathologically annotated tissue specimens for medical research). This paper examines if tissue blocks, identified by localized computer searches at participating institutions, can be retrieved in adequate quantity and quality to support medical researchers. Four centers evaluated pathology reports (1990–2005) for common and rare tumors to determine the percentage of cases where suitable tissue blocks with tumor were available. Each site generated a list of 100 common tumor cases (25 cases each of breast adenocarcinoma, colonic adenocarcinoma, lung squamous carcinoma, and prostate adenocarcinoma) and 100 rare tumor cases (25 cases each of adrenal cortical carcinoma, gastro-intestinal stromal tumor [GIST], adenoid cystic carcinoma, and mycosis fungoides) using a combination of Tumor Registry, laboratory information system (LIS) and/or SPIN-related tools. Pathologists identified the slides/blocks with tumor and noted first 3 slides with largest tumor and availability of the corresponding block. Common tumors cases (n = 400), the institutional retrieval rates (all blocks) were 83% (A), 95% (B), 80% (C), and 98% (D). Retrieval rate (tumor blocks) from all centers for common tumors was 73% with mean largest tumor size of 1.49 cm; retrieval (tumor blocks) was highest-lung (84%) and lowest-prostate (54%). Rare tumors cases (n = 400), each institution's retrieval rates (all blocks) were 78% (A), 73% (B), 67% (C), and 84% (D). Retrieval rate (tumor blocks) from all centers for rare tumors was 66% with mean largest tumor size of 1.56 cm; retrieval (tumor blocks) was highest for GIST (72%) and lowest for adenoid cystic carcinoma (58

    Purpose: To assess the outcomes, toxicity, and quality of life (QOL) of patients with primary parotid carcinoma treated with surgery and postoperative radiotherapy at the Daniel den Hoed Cancer Center. Methods and Materials: Between 1995 and 2010, 186 patients with parotid carcinoma were treated with parotidectomy with or without neck dissection, followed by radiotherapy. Elective nodal irradiation (ENI) was applied to high-risk, node-negative disease. End points were locoregional control (LRC), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS), late toxicity, and QOL. Results: After a median follow-up of 58 months (range, 4-172 months), the 5-year Kaplan-Meier estimates for LRC, DFS, CSS, and OS were 89%, 83%, 80%, and 68%, respectively. Forty-five events were reported: 24 distant metastases (DM) and 21 locoregional failures (LRF). Event-free survival rates by histological types were 89%, 78%, 76%, 74%, and 70% for acinic cell, mucoepidermoid, adenoid cystic, adenocarcinoma, and squamous cell carcinoma, respectively. More LRF were reported in patients with squamous cell and high-grade mucoepidermoid carcinoma (21% and 19%, respectively) than in patients with other histological types (p = 0.04) and more DM in patients with adenoid cystic and adenocarcinoma (20% and 19%, respectively) than in patients with other types (p = 0.03). None of the high-risk node-negative patients who received ENI developed regional failure. On multivariate analysis, T stage, N stage, grade, and presence of perineural invasion and facial paralysis correlated significantly with DFS. The 5-year cumulative incidence of grade {>=}2 late toxicity was 8%. QOL scores deteriorate during and shortly after treatment but returned in almost all scales to baseline scores within 6 months. Conclusions: Of the entire group, surgery and postoperative radiotherapy resulted in excellent outcomes with minimal side effects and preservation of good QOL scores. However, in

    Full Text Available As glândulas ceruminosas são glândulas apócrinas modificadas encontradas na região profunda da derme que reveste a porção cartilaginosa do meato acústico externo. Os tumores originados dessas glândulas são raros. Existem controvérsias em relação ao termo ceruminoma, que nos parece impróprio. Na verdade, esses tumores são atualmente classificados como adenoma, adenocarcinoma, carcinoma adenóide cístico e adenoma pleomórfico. Relatamos o caso de uma mulher de 39 anos, apresentado-se com cefaléia, hipoacusia e zumbidos à direita, além de vertigem e náuseas. A TC de crânio evidenciou tumoração do ouvido médio, invadindo os limites ósseos e cartilaginosos, com extensão intracraniana. Foi submetida a cirurgia, com exérese parcial do tumor, seguida de radioterapia (6000 cG. A histologia mostrou tratar-se de carcinoma adenóide cístico de glândulas ceruminosas. A paciente apresentou no pós-operatório paralisia facial periférica à direita, mantendo os déficits anteriores. Após um ano da cirurgia encontra-se estável clinicamente.Ceruminous glands are modified apocrine glands, confined to the skin lining of the cartilaginous part of the external auditory meatus. Tumors arising from these glands are rare. Controversy exists regarding the term "ceruminoma". Actually this neoplasia should be classified as adenoma, adenocarcinoma, adenoid cystic carcinoma and pleomorphic ceruminous adenoma. We report a 39-year-old woman first seen at Santa Casa of Belo Horizonte, in 1998, presenting with headache, nausea, vertigo, hearing loss and tinitus on the right for the past two years. CT scan showed a tumor eroding cartilaginous and bony limits with intracranial invasion. She was submitted to multidisciplinary treatment with surgery followed by radiotherapy (6000 cG. Histology showed a ceruminous adenoid cystic carcinoma. The patient manifested a right peripherical facial palsy and had no recovery of the previous deficits. After one

    Allergic rhinitis (AR) is a very common childhood disease that is associated with a significant reduction in the patients' quality of life. Its treatment combines educating the patients and their parents, immunotherapy and drug administration. However, even the best approach does not relieve the symptoms of a number of patients. Alternative therapies are particularly needed for children because the fear of adverse events frequently reduces parental compliance to the prescribed drugs, and immunotherapy is less easy to administer than in adults. In this prospective investigator-blinded study we evaluated whether children, with a documented history of seasonal grass pollen-related AR, benefit from nasal irrigation by assessing the effects on nasal signs and symptoms, on middle ear effusion and on adenoidal hypertrophy. We randomized children aged 5 to 9 years (median age 82 months) to normal saline or hypertonic saline (a 2.7% sodium chloride solution), administered twice-daily using a disposable 20 ml syringe, or no treatment. Nasal symptoms (rhinorrhea, itching, sneezing, nasal obstruction), swelling of turbinates, adenoid hypertrophy or middle ear effusion were assessed at baseline and after 4 weeks of treatment. Two hundred and twenty children (normal saline: 80; hypertonic saline: 80; no treatment: 60) completed the study. After four weeks, all the considered items were significantly reduced in the group receiving hypertonic saline (P < 0.0001), whereas in the group receiving normal saline only rhinorrhea (P = 0.0002) and sneezing (P = 0.002) were significantly reduced. There was no significant change in any of the items in the control group. The duration of oral antihistamines was significantly lower in the children receiving hypertonic saline than in those treated with normal saline or in controls. No adverse events were reported and parental satisfaction and compliance with the procedure were globally very good, regardless of the solution used. Using our

    Full Text Available Abstract Background Allergic rhinitis is one of the commonest atopic diseases which contribute to significant morbidity world wide while its epidemiology in Tanzania remains sparse. There was paucity of information regarding allergic rhinitis in our setting; therefore it was important to conduct this study to describe our experience on allergic rhinitis, associated co-morbidities and treatment outcome in patients attending Bugando Medical Centre. Methods This was descriptive cross-sectional study involving all patients with a clinical diagnosis of allergic rhinitis at Bugando Medical Centre over a three-month period between June 2011 and August 2011. Data was collected using a pre-tested coded questionnaire and analyzed using SPSS statistical computer software version 17.0. Results A total of 190 patients were studied giving the prevalence of allergic rhinitis 14.7%. The median age of the patients was 8.5 years. The male to female ratio was 1:1. Adenoid hypertrophy, tonsillitis, hypertrophy of inferior turbinate, nasal polyps, otitis media and sinusitis were the most common co-morbidities affecting 92.6% of cases and were the major reason for attending hospital services. Sleep disturbance was common in children with adenoids hypertrophy (χ2 = 28.691, P = 0.000. Allergic conjunctivitis was found in 51.9%. The most common identified triggers were dust, strong perfume odors and cold weather (P χ2 = 4.583, P = 0.032. In this study family history of allergic rhinitis was not a significant risk factor (P =0.423. The majority of patients (68.8% were treated surgically for allergic rhinitis co morbidities. Post operative complication and mortality rates were 2.9% and 1.6% respectively. The overall median duration of hospital stay of in-patients was 3 days (2 – 28 days. Most patients (98.4% had satisfactory results at discharge. Conclusion The study shows that allergic rhinitis is common in our settings representing 14.7% of all

    Between 1970 and 1975 cytological examination was applied to the diagnosis of nasopharyngeal malignancies in a series of 216 consecutive patients who had either a tumour in the nasopharynx or clinical signs of nasopharyngeal carcinoma, or who were locally asymptomatic but had enlarged cervical lymph nodes. Smears were taken by introducing a small rough pad of compressed gauze through the mouth into the nasopharynx with an upward-angled forceps. In each case the cytological smear was taken immediately before biopsy; often, a lymph node was removed subsequently. When morphological diagnoses were doubtful and histological findings were at variance with positive cytological findings, the patients were reexamined clinically, and diagnosis was postponed. The case material was made up of 90 nasopharyngeal carcinomas, 24 lymphomas, one malignant melanoma, one adenoid cystic carcinoma and 100 patients without malignancies. Cytological findings from the first smear were positive in 77.8% of nasopharyngeal carcinomas, in 66.6% of lymphomas and in the cases of melanoma and adenoid cystic carcinoma. There were no false-positive results. When the nasopharyngeal carcinomas were subdivided into undifferentiated carcinomas of the nasopharyngeal type and squamous-cell carcinomas, cytological findings were positive in ,0% and 73%, respectively. Positivity of histological findings was distributed as follows: 91.7% for malignant lymphomas, 86.6% for undifferentiated carcinomas and 86.6% for squamous-cell carcinomas. With respect to clinical suspicion of malignancy, positive cytological findings were obtained in 50% of clinically occult cases and in 84.6% of patients with obvious malignancies; intermediate figures were found for clinically doubtful (64.3%) and for highly suspicious (77.8%) cases. Cyto-histological concordance was shown in 70% of cases; false-negative histological results were obtained in 7.8% and false-negative cytological results in 16.6% of cases. Combined cyto

    High-risk human papillomavirus (HPV) is an established cause of head and neck carcinomas arising in the oropharynx. The presence of HPV has also been reported in some carcinomas arising in the sinonasal tract, but little is known about their overall incidence or their clinicopathologic profile. The surgical pathology archives of The Johns Hopkins Hospital were searched for all carcinomas arising in the sinonasal tract from 1995 to 2011, and tissue microarrays were constructed. p16 immunohistochemical analysis and DNA in situ hybridization for high-risk types of HPV were performed. Demographic and clinical outcome data were extracted from patient medical records. Of 161 sinonasal carcinomas, 34 (21%) were positive for high-risk HPV DNA, including type 16 (82%), type 31/33 (12%), and type 18 (6%). HPV-positive carcinomas consisted of 28 squamous cell carcinomas and variants (15 nonkeratinizing or partially keratinizing, 4 papillary, 5 adenosquamous, 4 basaloid), 1 small cell carcinoma, 1 sinonasal undifferentiated carcinoma, and 4 carcinomas that were difficult to classify but exhibited adenoid cystic carcinoma-like features. Immunohistochemistry for p16 was positive in 59/161 (37%) cases, and p16 expression strongly correlated with the presence of HPV DNA: 33 of 34 (97%) HPV-positive tumors exhibited high p16 expression, whereas only 26 of 127 (20%) HPV-negative tumors were p16 positive (Pcarcinomas occurred in 19 men and 15 women ranging in age from 33 to 87 years (mean, 54 y). A trend toward improved survival was observed in the HPV-positive group (hazard ratio=0.58, 95% confidence interval [0.26, 1.28]). The presence of high-risk HPV in 21% of sinonasal carcinomas confirms HPV as an important oncologic agent of carcinomas arising in the sinonasal tract. Although nonkeratinizing squamous cell carcinoma is the most common histologic type, there is a wide morphologic spectrum of HPV-related disease that includes a variant that resembles adenoid cystic carcinoma.

    Full Text Available Human adenoviruses are known to persist in T-lymphocytes of tonsils, adenoids and intestinal tract. The oncogenic potential of different adenovirus types has been widely studied in rodents, in which adenovirus inoculation can induce multiple tumors such as undifferentiated sarcomas, adenocarcinomas and neuroectodermal tumors. However, the oncogenic potential of this virus has never been proven in human subjects. Using a highly sensitive broad-spectrum qRT-PCR, we have screened a set of different human sarcomas including leiomyosarcoma, liposarcoma and gastro intestinal stroma tumors. Primers binding the viral oncogene E1A and the capsid-coding gene Hexon were used to detect the presence of adenovirus DNA in tumor samples. We found that 18% of the tested leiomyosarcomas and 35% of the liposarcomas were positive for the presence of adenovirus DNA, being species C types the most frequently detected adenoviruses. However, only in one sample of the gastro intestinal stroma tumors the virus DNA could be detected. The occurrence of adenovirus in the tumor sections was confirmed by subsequent fluorescence in-situ-hybridization analysis and co-staining with the transcription factor Bcl11b gives evidence for the presence of the virus in infiltrating T-lymphocytes within the tumors. Together these data underline, for the first time, the persistence of adenovirus in T-lymphocytes infiltrated in muscular and fatty tissue tumor samples. If an impaired immune system leads to the viral persistence and reactivation of the virus is involved in additional diseases needs further investigation.

    Whilst rhabdomyosarcoma (RMS) is the third most common solid tumour in children, congenital RMS of the tongue is extremely rare and usually present as painless progressive mass since birth (Dagher and Helman in Oncologist 4:34-44, 1999; Childs and Goudy in Int J Pediatr Otorhinolaryngol 5:126-128, 2010). In neonates, presentation with respiratory distress is unexpected as neonates are preferential nasal breathers and restricted oral breathing due to tumour usually poses no problem. We herein report a case of rhabdomyosarcoma of the tongue with co-existent unilateral choanal atresia, presenting with respiratory distress. The baby developed upper respiratory tract infection following which developed severe respiratory distress. Airway symptoms were precipitated as there was combined obstruction of both the nostrils due to infection or adenoid enlargement and unilateral chonal atresia. Treatment of respiratory distress in the presence of RMS and bilateral nasal pathology must first prioritise the security of the airway, before taking a multi-factorial approach to the therapy of the lingual mass (Childs and Goudy in Int J Pediatr Otorhinolaryngol 5:126-128, 2010). This case illustrates the importance of vigilance with respect to co-existent nasal pathology, in order to avoid the occurrence of complete airway obstruction. We therefore feel that any diagnosis of lingual RMS should warrant a formal examination of both nasal cavities. PMID:27408448

    It is well known that FDG Fusion PET (PET) has a good diagnostic nature in patient with head and neck cancer. But, there is a few PET study about salivary gland cancer which had a different histopathology. We analyzed the usefulness of PET in patients with biopsy confirmed salivary gland cancer. Eleven patients (M: F=8: 3, age = 61.29.3 yr) with PET and CT exam were enrolled (The interval=4263 day). All of them didn't have previous chemotherapy or radiotherapy. PET and CT were compared with pathologic TNM stage. All of eleven patients had salivary gland biopsy and confirmed as malignancy (parotid gland: submandibular gland =8: 3). Pathologic type was adenocarcinoma (1), poor differentiated carcinoma (1), mucoepidermoid carcinoma (n=2), adenoid cystic carcinoma (2), salivary duct carcinoma (2), carcinoma ex pleomorhic adenoma (3). One patient didn't operation due to metastatic lesions which was detected on PET. From 10 patients, PET had a 100 % of tumor detection rate (maxSUV =4.72.1) and 60 %(6/10) of coincident result with pathologic N stage. CT had 100 % of tumor detection rate and 40% (4/10) and 60 % (6/10) of coincidence results with TN stage. Even though PET didn't have a better coincidence with pathologic N stage than that of CT, it is useful method to discriminate metastatic lesion.

    Our aim was to define typical magnetic resonance (MRI) findings in malignant and benign parotid tumours. This study is based on retrospective evaluation of pre-surgical MRI of 94 patients with parotid gland tumours. Histology results were available for all tumours. There were 69 cases of benign (73%) and 25 cases of malignant (27%) tumours, including 44 pleomorphic adenomas, 18 Warthin's tumours, 7 various benign tumours, 6 squamous cell carcinomas, 3 carcinoma ex pleomorphic adenomas, 2 mucoepidermoid carcinomas, 1 adenoid cystic carcinoma and 13 various malignant tumours. The following MRI parameters were evaluated: shape, site, size, margins, signal intensity (SI) on T1w and T2w images, contrast enhancement, signal of cystic content, presence or absence of a capsule, perineural spread, extraglandular growth pattern and cervical adenopathy. Statistical analysis was performed to identify the MRI findings most suggestive of malignancy, and to define the most typical MRI pattern of the most common histologies. Ill-defined margins (p parotid inferior process (p < 0.001) and mild or incomplete contrast enhancement (p = 0.01). SI on T1w and T2w images and contrast enhancement enables differential diagnosis between pleomorphic adenoma and Warthin's tumour. PMID:26824912

    A retrospective analysis was performed on 55 patients with malignant parotid tumor who were treated with radiation therapy between March, 1979 and July, 1989. Of these patients, 8 patients received radiation therapy(RT) alone and 47 patients were treated with combined operation and radiation therapy(OP+RT). The follow-up period of the survivors ranged form 1 to 129 months with a median of 48 months. The common histologic types were mucoepidermoid carcinoma (25 cases), malignant mixed tumor(12 cases), adenoid cystic carcinoma(6 cases). The 5 and 10 year local control rate were 69.8% and 65.7% in all patients. In OP+RT group, prognostic factors related to local control were histologic grade, tumor size, lymph node metastasis. Resection of facial nerve did not affect the local control rate significantly(p=0.129). Distant metastasis developed in 23.6% of patients, mostly to the lung. Actuarial overall survival rate was 72.2% at 10 years and formed plateau after 5 years. Disease-free (NED) survival rate was 49.4% at 10 years and was better achieved in OP+RT group and low grade lesions. Based on our result, a well planned postoperative RT following parotidectomy is highly efficacious in controlling malignant tumors of the parotid gland and preservation of facial nerve.

    Full Text Available The Rare Cancer Network (RCN was formed in the early 1990’s to create a global network that could pool knowledge and resources in the studies of rare malignancies whose infrequency prevented both their study with prospective clinical trials. To date, the RCN has initiated 74 studies resulting in 46 peer reviewed publications. The First International Symposium of the Rare Cancer Network took place in Nice in March of 2014. Status updates and proposals for new studies were heard for fifteen topics. Ongoing studies continue for cardiac sarcomas, thyroid cancers, glomus tumors, and adult medulloblastomas. New proposals were presented at the symposium for primary hepatic lymphoma, solitary fibrous tumors, Rosai-Dorfman disease, tumors of the ampulla of Vater, salivary gland tumors, anorectal melanoma, midline nuclear protein in testes carcinoma, pulmonary lymphoepithelioma-like carcinoma, adenoid cystic carcinoma of the trachea, osteosarcomas of the mandible, and extra-cranial hemangiopericytoma. This manuscript presents the abstracts of those proposals and updates on ongoing studies, as well a brief summary of the vision and future of the RCN.

    Full Text Available Background: Human beings are conditioned to breathe through the nose and feed through the mouth, when this physiological mechanism is interrupted facial and general growth is also affected. Objective: To characterize Angle´s Class II malocclusions in oral breathers with nasorespiratory and orthopedic dysfunctions. Method: A correlational, observational and descriptive study was developed from December 2004 to November 2005 including clinical examination of 833 children out of which 60 were selected to take part in this study. Each case was analyzed in Orthodontia, Orthopedics and Otolaryngology consultations. The studied variables were: age, sex, nasorespiratory disorders, orthopedic dysfunctions, dental-maxillofacial irregularities. Results: The mot frequent dental-maxillofacial irregularities were: bilabial incompetence, transversal micrognathism, vestibular version, overjet and overbite. The most important nasorespiratory dysfunctions found in these children were adenoiditis, and tonsil hypertrophy. The most outstanding orthopedic dysfunction was ciphosis. Conclusion: It is conclusive to state that there is a high relationship between dentomaxillofacial anomalies and nasorespiratory and orthopedic dysfunctions.

  9. Radiation to the head, neck, and upper thorax of the young and thyroid neoplasia

    International Nuclear Information System (INIS)

    It is now generally accepted that an association exists between external radiation administered to the head, neck and upper thorax of infants, children and adolescents and the subsequent development of neoplastic changes in the thyroid gland. Until recent years external radiation was frequently administered to shrink an enlarged thymus, or for the treatment of tonsillitis, adenoiditis, hearing loss, hemangioma, acne, tinea capitis and other conditions. During the course of these treatments, the thyroid gland was exposed to scattered radiation. It is stressed that the use of external radiation therapy was then accepted practice and its value was attested by many. The likelihood of adverse effects was not initially apparent, primarily because of the long periods of time between the administration of the therapy and the recognition of changes in the thyroid. The availability and effectiveness of other therapeutic measures and the growing concern about the delayed effects of radiation therapy when administered to the young for relatively benign conditions has, in recent years, largely eliminated use of this form of therapy, except in a few unusual conditions

    2013-12-01

    Full Text Available By means of Doppler echocardiography there have been studied disturbances of intracardiac hemodynamics in 44 children aged 8-17 years with chronic rheumatic cardiac disease and developed mitral aortal and combined heart defects, as well as in chronic rheumatic cardiac disease without developed valvar defect. Differential approach has been defined to administration of inhibitors of angiotensin-converting factor in rheumatic heart defects: developed insufficiency of mitral and/or aortal valves II-III stage leads to remodeling of the left heart portions with developing chronic insufficiency of blood circulation, being an index for prolonged, not less than a year usage of the angiotensin-converting factor. In the presence of isolated mitral regurgitation, I stage in children with chronic rheumatic cardiac disease usage of the angiotensin-converting factor may be cancelled due to insignificant disturbances of valvar hemodynamics and a small risk of developing blood circulation insufficiency. Timely sanation of chronic infection foci in nasopharynx (conservative and surgical treatment of chronic tonsillitis, adenoid vegetations, therapy of hemolytic streptococcus presence decreases risk of developing rheumatic heart defect in children suffered acute rheumatic fever.

    Salivary gland tumours are an important part of the Oral and Maxillofacial Pathology, unfortunately, only few studies on these tumours have been done in Latin-American population. The aim of this study was to compare demographic data on salivary gland tumours in a Mexican sample with those previously published from Latin American and non-Latin American countries. All cases of salivary gland tumours or lesions diagnosed in our service were reviewed. Of the reviewed cases,67 were confirmed as salivary gland tumours. Out of these 64.2% were benign neoplasms, 35.8% were malignant and a slight female predominance (56.7%) was found. The most common location was palate followed by lips and floor of the mouth. Mean age for benign tumours was 40.6 years with female predominance (60.5%). Mean age for malignant tumours was 41 years and female predominance was found again. Palate followed by retromolar area were the usual locations. Pleomorphic adenoma (58.2%), mucoepidermoid carcinoma (17.9%) and adenoid cystic carcinoma (11.9%) were the more frequent neoplasms. All retromolar cases were malignant and all submandibular gland tumours were benign. We found a high proportion of salivary gland neoplasms in children. Our results showed that differences of the studied tumours among our sample and previously reported series exist. These differences can be related to race and geographical location.

  14. Application of dynamic CT for various diseases in the oral and maxillofacial region

    International Nuclear Information System (INIS)

    Objective: To investigate whether dynamic CT enables quantitative differentiation between inflammation, benign tumors, and malignant tumors in oral and maxillofacial regions. Methods: Sixteen malignant tumors (14 squamous cell Ca, one adenoid cystic Ca, one mucoepidermoid Ca), six benign tumors (one Warthin tumor, two pleomorphic adenomas, one lipoma, one Schwanoma, one hemangioma), and seven inflammation cases (three submandibular adenitis, two osteomyelitis, two perimandibular inflammations) were examined. Contrast agent (0.8 ml/kg) was injected intravenously at 5 ml/s. CT (Toshiba TCT 900S) scanning was performed at the time of the beginning of contrast medium injection. Parameters from the time-density curve were investigated: peak height (PH), relative CT value from the base CT value when the curve reached peak point; peak time (PT), the time when the curve reaches the peak point from contrast medium infusion; transit time (TT), time between two transit points on the time-density curve; and peak time ratio (PR), the ratio of peak time from the lesion to the artery and peak time from the vein to the artery. Results: PH was highest in inflammation, followed by malignant tumors and benign tumors. TT was significantly longer in benign tumor cases compared with malignant tumor and inflammation cases. PR for malignant tumor and inflammation were between the artery and vein phase, and that for benign tumor was beyond the vein phase. Conclusion: Parametrical analysis of a contrast enhanced dynamic CT study may serve to differentiate the lesions in the oral and maxillofacial region

    Mechanisms leading to Obstructive Sleep Apnea Syndrome (OSAS) in obese children are not well understood. We previously analyzed polysomnographic and demographic data to study the anatomical characteristics of the upper airway and body composition in two groups of obese children with and without OSAS, where object volume was evaluated. In this paper, in order to better understand the disease we expand the analysis considering a variety of features that include object-specific features such as size, surface area, sphericity, and image intensity properties of fourteen objects in the vicinity of the upper airway, as well as inter-object relationships such as distance between objects. Our preliminary results indicate several interesting phenomena: volumes and surface areas of adenoid and tonsils increase statistically significantly in OSAS. Standardized T2-weighted MR image intensities differ statistically significantly between the two groups, implying that perhaps intrinsic tissue composition undergoes changes in OSAS. Inter-object distances are significantly different between the two groups for object pairs (skin, oropharynx), (skin, fat pad), (skin, soft palate), (mandible, tongue), (oropharynx, soft palate), (left tonsil, oropharynx), (left tonsil, fat pad) and (left tonsil, right tonsil). We conclude that treatment methods for OSAS such as adenotonsillectomy should respect proportional object size relationships and spatial arrangement of objects as they exist in control subjects.

    Background Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. Material and Methods Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data included demographic information, clinical manifestations, treatment plans, and histopathology of the tumor. Results There were 69 (62.16%) male and 42 (37.83%) female patients (male-to-female ratio of 1.6:1), with a median age of 49±12.2 years (range 21 to 88 years). A high level of occurrence was noticed in the fifth (26.3%) decade of life. The most frequent histological types were squamous cell carcinoma (43.5%) and adenoid cystic carcinoma (19%). Among clinical manifestations, nasal obstruction was the most frequent followed by diplopia, and facial swelling. Fifty three patients (47.74%) were treated with combined approach of surgery and radiation therapy. Conclusions Paranasal sinuses malignancies are rare conditions with nonspecific symptoms which make early diagnosis of the lesions more challenging. The optimal therapeutic protocol for patients suffering from these tumors is still a somewhat controversial entity and requires further studies. Key words:Paranasal sinuses, malignancy, surgery,radiotherapy. PMID:27475693

  17. Clinical study on osteoradionecrosis of the jaws

    International Nuclear Information System (INIS)

    In the present study osteoradionecrosis which had developed after radiotherapy for malignant tumor was studied clinically and therapeutically and the following results were obtained. 1. The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5. As the method of treatment, sequestrectomy was performed in 14 of 19 cases of the limited area type and 4 of 11 cases of the wide range type and excision of the jaws in 4 cases. 6. Hyperbaric oxygen therapy was carried out in 3 cases and had good effect. (J.P.N.)

    Full Text Available Purpose: This retrospective study was done to report our experience with the management of patients with primary malignant tumors of minor salivary glands that were treated with various combinations of surgery, radiation, and chemotherapy and to review treatment outcome. Methods: The records of all patients with malignant minor salivary gland tumors presenting for treatment at our department between 2000 and 2010 were retrospectively reviewed. Variables were collected and outcome measures were defined in terms of overall survival, disease-free survival. Descriptive statistics were compiled and statistically evaluated. Survival was described using the Kaplan-Meier method. Results: Twenty eight patients (10 males and 18 females ranging in age from 18 to 80 years (median, 64 years met the criteria for inclusion in the study. The majority of tumors were located in the oral cavity (n = 20, followed by nasal cavity and paranasal sinuses (n = 8. Adenoid cystic carcinoma was the most common neoplasm (n = 18. All patients were treated with surgery as the primary modality. Neck dissection was performed in 18% of patients, and all patients (n = 28 were treated with adjuvant external beam radiation therapy to a dose of 50 to 60 Gy. The disease-free survival rate and overall survival at 5 years were 80% and 85%, respectively. Conclusion: Postoperative radiation therapy is effective in preventing local recurrence in most patients with minor salivary gland tumors after gross total excision.

    Full Text Available Background: There are malignant and benign intra-oral pathologic lesions of salivary gland. Reevaluation of paitants’ age, sex and location of lesions can help to have better diagnosis and accurate comparison with other studies in other countries.Materials and Method: In a retrospective study, cases of benign and malignant salivary gland during 1369 to 1385 retrieved from the files and histopathologic records of cases diagnosed at Shiraz School of Dentistry.Results: From 110 cases, 70 cases had mucocele, 15 had sialadenitis, 7 of pleomorphic adenoma, 3 mucoepidermoid carcinoma and the remaining 3 cases had adenoid cystic carcinoma. The mean age for patients with mucoceles was 20. 8 and the most common site were mucosa of the lower lips. The mean age for patients with sialadenitis was 34. The most common sites were mucosa of the lips and submandibular gland. The mean age of pleomorphic adenoma was 32 and the most common site was hard palate. Mucoepidermoid carcinoma was detected in 3 males at the ages of 44 to 54. Adenoidcystic carcinoma was seen in 3 patients at the ages of 18 to 32.Conclusion: Mucocele was the most common lesion (71% and pleomorphic adenoma constituted 70% of all salivary gland diseases and 53% of all neoplasms. Mucocele was the most common lesion in lower lip, in the second and third decades with equal gender distribution. Pleomorphic adenoma occurs more in third and fourth decades and the most common site was hard palate

  20. Cutaneous cylindroma: it's all about MYB.

    Corda, Gabriele; Sala, Arturo

    2016-08-01

    Cutaneous cylindroma is a rare benign tumour that occasionally turns into malignant cylindrocarcinoma. The cancer can be sporadic or emerge in the context of Brooke-Spiegler syndrome (BSS), an inheritable condition characterized by mutation of the gene CYLD, encoding a tumour suppressor protein that controls the activity of the transcription factor NF-kB. Sporadic cylindromas present histological features shared with adenoid cystic carcinoma (ACC), a head and neck cancer originating from salivary or other exocrine glands. Like ACCs, sporadic cylindromas express, although at lower frequency, the aberrant fusion transcript MYB-NFIB. In a paper recently published in the Journal of Pathology, the research teams led by Neil Rajan and Goran Stenman demonstrate that CYLD-defective cyclindromas in BSS patients are negative for the MYB-NFIB fusion. Only the wild-type MYB oncoprotein is activated in the majority of these tumours. RNA interference studies in cells derived from BSS patients indicate that ablating MYB expression results in a striking reduction of cylindroma cell proliferation, suggesting that MYB plays a pivotal role in the biology of this cancer. The take-home message of the study is that activation of MYB, in its wild-type form or fusion derivatives, is a common feature of spontaneous and hereditary cylindromas, constituting a potentially actionable therapeutic target.

    Apoptosis plays an essential role in normal organism development which is one of the main types of programmed cell death to help tissues maintain homeostasis. Defective apoptosis can result in cell accumulation and therefore effects on tumor pathogenesis, progression and therapy resistance. A family of proteins, known as caspases, is typically activated in the early stages of apoptosis. Therefore, studying the kinetics of activation of caspases induced by antitumor drugs can contribute to antitumor drug discovery and explanation of the molecular mechanisms. This paper detected the Caspase-3 activity induced by cisplatin in human adenoid cystic carcinoma cell line (ACC-M), human hepatocellular liver carcinoma cell line (HepG2) and human epithelial carcinoma cell line (Hela) with stably expressing ECFP-DEVDDsRed (CD3) probe, a fluorescent probe consisting of Enhanced Cyan Fluorescent Protein (ECFP), red fluorescent protein (DsRed) and a linker with a recognition site of Caspase-3, by using the capillary electrophoresis (CE) and fluorescence resonance energy transfer (FRET) imaging system. Under the same concentration of cisplatin, ACC-M cells responded the most rapidly, and then HepG2 cells and Hela cells, respectively, in the early 30 hours. Later, HepG2 cells represented acceleration in the Caspase-3 activation speed and reached full activation the earliest comparing to other two cell types. The results demonstrated that ACC-M cell is more sensitive than the other two cell types under the treatment of cisplatin.

    Full Text Available Acute respiratory viral infections (ARVI and influenza are among the topical problems of healthcare. The children’s morbidity index in preschool educational institutions in Krasnoselsky district of St. Petersburg in 2008–2014 varied from 1359.6 to 1768.5 per 1000 children attending these institutions. In general educational schools the morbidity index in the aforesaid period were 422.6–521.6 (p < 0.001. From 49.3 to 55.4% of children were vaccinated against influenza; from 3600 to 4700 children annually stayed unimmunized due to medical contraindications and parents’ refusals from prophylactic immunization. The research objective is clinical-epidemiological substantiation of effectiveness of application of Echinacea botanical medicine to reduce the ARVI morbidity and the rate of complications after the disease among children attending educational institutions. As a result of the research it was established that the ARVI morbidity index in the group of the children who received the Echinacea preparation was 76.8; in the comparison group it was 94.2 per 100 people (p < 0.01; RR = 0.80; CI = 0.7–0.9. The rate of complications (bronchitis, otitis, adenoiditis, pneumonia, sinusitis among the children who received the preparation was 2–4.8 times lower.

    Midkine (MK), a heparin-binding growth factor,can regulate cell growth, survival and differentiation. MK is expressed at high levels in a variety of human carcinomas. Recently, the urine and serum MK concentration was analyzed in gastric cancer patient. However, the association of the cytokine mRNA expression with the categorical clinicopathological variables of the tumors and the location of its protein expression in the tumor tissues are still elusive. MK mRNA expression from the surgically resected specimens of healthy gastric tissues (9 cases), gastric cancer tissues and the matched non-cancerous tissues adjacent to the cancer (37 cases) were assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time PCR. Immunohistochemical analysis was performed to locate MK in gastric cancer. The expression of MK mRNA in gastric cancer was much higher in tumor tissues than that in the non-cancerous tissues and control tissue samples. And its expression was significantly associated with the pTNM stage and distant metastasis, but not with the differentiation grade, tumor size and nodal involvement. MK protein was ubiquitous in the tumor, especially in the adenoid part of tumors. In addition, it was found in the cytoplasm of tumor cells and highly concentrated in nucleus and nucleolus. The expression level and location of MK in gastric tumor tissues of Chinese Patients may be related to the tumor genesis and progression. Further study is necessary on the mechanism of MK in gastric tumorigenesis and tumor growth.

    Background/Objective There have been several operative techniques for adenoidectomy and their efficacy and morbidity are different according to the technique. This prospective multicenter study was aimed to compare the efficacy and morbidity of coblation adenoidectomy (CA) with those of power-assisted adenoidectomy. Study Design Prospective multi-institutional study. Methods Children who underwent CA, power-assisted adenoidectomy with cauterization (PAA+C) or without cauterization (PAA-C) due to adenoid hypertrophy were enrolled from 13 hospitals between July 2013 and June 2014. Mean operation time, degree of intraoperative bleeding and postoperative bleeding rate were evaluated. Results A total of 388 children (mean age ± standard deviation = 6.6 ± 2.5 years; 245 males and 143 females) were included. According to the adenoidectomy technique, the children were classified into 3 groups: (1) CA (n = 116); (2) PAA+C (n = 153); and (3) PAA-C (n = 119). Significant differences were not found in age and sex among three groups. In the CA group, mean operation time was significantly shorter (P < 0.001) and degree of intraoperative bleeding was significantly less (P < 0.001) compared to PAA+C or PAA-C group. Delayed postoperative bleeding rate of PAA-C group was significantly higher than that of CA or PAA+C group (P = 0.016). Conclusions This prospective multicenter study showed that CA was superior to PAA in terms of mean operation time and degree of intraoperative bleeding. PMID:26267337

    Anoctamin-1 (ANO1) (DOG1, TMEM16a) is a calcium-activated chloride channel initially described in gastrointestinal stromal tumors, but now known to be expressed in a variety of normal and tumor tissues including salivary tissue in murine models. We herein perform a comprehensive survey of DOG1 expression in 156 cases containing non-neoplastic human salivary tissues and tumors. ANO1 mRNA levels were significantly higher (8-fold increase, Pcells, striated and excretory ducts were invariably negative. All acinic cell carcinomas (n=28) were DOG1 positive demonstrating a complex mixture of intense (3+) apical membranous, cytoplasmic and complete membranous staining. Most ductal tumor types were negative or only showed a subset of positive cases. Within the biphasic tumor category, adenoid cystic carcinomas (18/24 cases) and epithelial-myoepithelial carcinomas (8/15 cases) were frequently positive, often showing a distinctive combined apical ductal and membranous/cytoplasmic myoepithelial staining profile. Thus, DOG1 staining is a marker of salivary acinar and to a lesser extent intercalated duct differentiation. Strong staining can be used to support the diagnosis of acinic cell carcinoma. DOG1 may also be a marker of a 'transformed' myoepithelial phenotype in a subset of biphasic salivary gland malignancies.

    Cephalometry is useful as a screening test for anatomical abnormalities in patients with obstructive sleep apnoea syndrome (OSAS). To evaluate comprehensively the cephalo metric features of children with OSAS, with or without adenotonsillar hypertrophy, and to elucidate the relationship between cephalometric variables and apnoea-hypopnoea index (AHI) severity. The study population consisted of 39 children, aged 4-12 years, with OSAS. Cephalometry was analysed using 11 measurements of the bony structures, their relationships and the size of the airways. Additionally, adenoid and tonsillar hypertrophy were graded. Cranial base angles (BaSN and BaSPNS) were found to correlate with increasing levels of AHI scores (P<0.001). Protrusion of the maxilla (SNA) and mandible (SNB) did not correlate with AHI scores (P>0.05). The length of the mandibular plane (GnGo) and the minimal posterior airway space (MPAS) were inversely correlated with AHI scores (P<0.001). There was positive correlation between MPAS and GnGo (r=0.740, P<0.001), and negative correlation between MPAS and gonial angle (ArGoGn) (r=-0.541, P<0.001). There was significant correlation between cephalometric data and adenotonsillar hypertrophy concerning BaSN, BaSPNS, ArGoGn, GnGoH, BaN-GnGo, MPAS, GnGO and MPH. (orig.)

    Adaptive humoral immune responses in the airways are mediated by B cells and plasma cells that express highly evolved and specific receptors and produce immunoglobulins of most isotypes. In some cases, such as autoimmune diseases or inflammatory diseases caused by excessive exposure to foreign antigens, these same immune cells can cause disease by virtue of overly vigorous responses. This review discusses the generation, differentiation, signaling, activation, and recruitment pathways of B cells and plasma cells, with special emphasis on unique characteristics of subsets of these cells functioning within the respiratory system. The primary sensitization events that generate B cells responsible for effector responses throughout the airways usually occur in the upper airways, tonsils, and adenoid structures that make up the Waldeyer ring. On secondary exposure to antigen in the airways, antigen-processing dendritic cells migrate into secondary lymphoid organs, such as lymph nodes, that drain the upper and lower airways, and further B-cell expansion takes place at those sites. Antigen exposure in the upper or lower airways can also drive expansion of B-lineage cells in the airway mucosal tissue and lead to the formation of inducible lymphoid follicles or aggregates that can mediate local immunity or disease.

    longest apnea time between the mild group and the moderate group( P > 0. 05 ) . The longest apnea time of severe group was prolonged significantly compared with the other two groups( P < 0. 05 ) . There was significantly diflerent in hypopnea among three groups ( P < 0. 05 ) , and the severe group had the highest total number of hypopnea. There was significantly different in the longest hypopnea among three groups(P < 0. 05 ) ,and the severe group had the highest the longest hypopnea. There was no significant difference in snoring frequency between moderate group and severe group( P > 0. 05 ) , and snoring in both groups was significantly increased compared with mild group( P < 0. 01 ) .There was aigmficantly different in AHI and ODI among the three groups( P <0. 01 ) , and the severe group had the highest AHI and ODI.There was a significant difference in prone position and the right of supine sleep time( P < 0. 05 ) . The severe group took a more prone and right position of sleep. There was no significant difference in the incidence of adenoids hypertrophy and tonsil hypertrophy( P > 0. 05 ) . but there was significant in the pharyngeal adenoids ratio A/N among the three groups.and the severe group had the largest ratio of A/N( P < 0. 01 ) . Conclusion There were different characteristics in clinical performance , sleep apnea events , sleep position of OSAHS children of varying degrees . The degree of adenoids hypertrophy and tonsils hypertrophy could not determine the severity of the disease. The degree of airway stenosis caused by adenoidal hypertrophy was the key to OSAHS severity. Polysomnography combined with imaging could evaluation the severity of OSAHS more accurately.

    Full Text Available A tonsila faríngea quando aumentada, pode causar obstrução nas vias aéreas superiores e levar à respiração bucal de suplência¹. Em alguns casos adenoidectomia e/ou adenoamigdalectomia são indicadas para remoção do fator obstrutivo, possibilitando a respiração nasal. Temos observado que algumas crianças mesmo sem apresentar queixas e/ou alterações vocais no período pré-operatório, desenvolvem uma qualidade vocal hipernasal após adenoidectomia12. Este artigo tem como objetivo descrever um caso de hipernasalidade após adenoidectomia e relatar o tratamento fonoaudiológico, bem como, os possíveis riscos e seqüelas após o procedimento cirúrgico.Hipertrophic adenoid is a frequent cause of obstruction of the upper respiratory tract and may lead to a mouth breathing condition. in some cases, surgical procedures such as adenoidectomy and or tonsillectomy are necessary to reestablish the nasal breathing. We have observed that following adenoidectomy, many children present with vocal hipernasality, even when there is no previous history or complains. In this paper, the authors describe a case of severe hipernasality following adenoidectomy, as well as detailed steps of the speech therapy approach. The risks and sequelae of this vocal condition related to adenoidectomy are also discussed.

    Streptococcal infections of oral tissues are mainly seen in young children who experience a variety of upper respiratory tract infections. The disease is characterized by fever, lymphadenopathy, and ulcers on the gingiva, lips, and tonsils. This case report presents an atypical streptococcal infection of the gingiva in an 18-year-old man. The patient was referred to the periodontology department complaining of a 2-month history of gingival enlargement. He had persistent fever (39.5 degrees C) and general malaise for 2 weeks. Intraoral examination revealed extremely inflamed and enlarged gingiva with spontaneous bleeding and suppuration. Based on the otolaryngologic consultation and the hematologic, immunologic, and microbiologic tests, the final diagnosis was an atypical streptococcal gingivitis with chronic adenoid-related mouth breathing and oral hygiene neglect as contributing factors. Treatment consisted of a broad-spectrum antibiotic regimen, supragingival and subgingival debridement, adenoidectomy, and scaling and root planing. A good response to nonsurgical therapy was achieved despite poor patient compliance, and no recurrence of gingival enlargement was observed after 1 year. Streptococcal gingivitis should be included in the differential diagnosis of suppurative gingival enlargements. Furthermore, chronic mouth breathing may initiate and/or contribute to this disease.

    Full Text Available Benign and malignant salivary gland tumours are clinically heterogeneous and show different histology. Little is known about the role of human herpes virus 8 (HHV-8, Epstein-Barr virus (EBV, and human papillomavirus (HPV infection in salivary gland neoplasms. We investigated the presence of the three viruses in formalin-fixed, paraffin-embedded tissue samples in a cohort of 200 different salivary gland tumours. We performed EBV-LMP-1 and HHV-8 and p16 immunohistochemistry, a specific chip based hybridization assay for detection and typing of HPV and a chromogenic in situ hybridization for EBV analysis. Only one case, a polymorphic low-grade carcinoma, showed HHV-8 expression and one lymphoepithelial carcinoma was infected by EBV. In 17 cases (9% moderate or strong nuclear and cytoplasmic p16 expression was detected. The HPV type was investigated in all of these cases and additionally in 8 Warthin’s tumours. In 19 cases HPV type 16 was detected, mostly in Warthin’s tumour, adenoid cystic carcinoma, and adenocarcinoma NOS. We concluded that HHV-8 infection and EBV infection are not associated with salivary gland cancer, but HPV infection may play a role in these tumour entities.

    Carbon-ion radiotherapy (C-ion RT) possesses physical and biological advantages. It was started at NIRS in 1994 using the Heavy Ion Medical Accelerator in Chiba (HIMAC); since then more than 50 protocol studies have been conducted on almost 4000 patients with a variety of tumors. Clinical experiences have demonstrated that C-ion RT is effective in such regions as the head and neck, skull base, lung, liver, prostate, bone and soft tissues, and pelvic recurrence of rectal cancer, as well as for histological types including adenocarcinoma, adenoid cystic carcinoma, malignant melanoma and various types of sarcomas, against which photon therapy could be less effective. Furthermore, when compared with photon and proton RT, a significant reduction of overall treatment time and fractions has been accomplished without enhancing toxicities. Currently, the number of irradiation sessions per patient averages 13 fractions spread over approximately three weeks. This means that in a carbon therapy facility a larger number of patients than is possible with other modalities can be treated over the same period of time.

    Full Text Available OBJECTIVE: To study the role of adenoidectomy in the management of otitis media with effusion. TYPE OF STUDY: A prospective clinical study. MATERIALS AND METHODS: 20cases studied in department of ENT, GMCH. The duration of study was from February 2011 to December 2011. Hearing loss assessment in the form of PTA & TYMPANOMETRY before and after adenoidectomy was done. OBSERVATIONS AND RESULTS: Children <14 years were included in the study. Sex wise distribution was observed. Patients categorized according to the symptoms, gender and degree of hearing loss. Satisfactory results observed after adenoidectomy in relation to the improvement in hearing loss. There can be some complications after adenoidectomy but in our studies proper precautions were taken and no complications seen. CONCLUSION: Adenoidectomy is a very effective surgical modality of treatment in patients who are having otitis media with effusion due to adenoid hypertrophy. Conservative management has no role and grommet insertion is not of much value. Adenoidectomy alone has been shown to produce otoscopic clearance of middle ear effusion, alteration of tympanometric status and improvement of hearing loss.

    Carinal reconstruction is a difficult technique combined with video-assisted thoracoscopic surgery (VATS). It has a high requirement on the operator's skills in operating thoracoscope and meanwhile requires the close cooperation from anesthesiologists. Tracheal intubation and ventilator-assisted ventilation are key steps to ensure the success of surgery. However, tracheal intubation itself may influence the exposure of surgical field and increase the difficulty of anastomosis. In close cooperation of anesthesiologists, we did not perform tracheal intubation; rather, we carried out non-intubated complete VATS carinal reconstruction in a patient with adenoid cystic carcinoma (ACC) of the lower trachea. The awake complete VATS carinal reconstruction was successfully performed. The anastomosis lasted about 36 hours, and the whole surgical procedure lasted 230 min. The intraoperative blood loss was about 80 mL. The patient recovered well 100 min after surgery. A semi-solid diet began 6 hours following the surgery. This non-intubated anesthesia method makes the surgery easier, especially during the anastomosis of stumps. It is feasible and safe to apply this anesthesia technique in carinal reconstruction.

    Hadrontherapy, a type of radiation therapy dealing with heavy charged particles, has become for the past decade one of the most sophisticated and attractive approach in the management of cancer. This is related with major technological innovations that have made available, at a relatively cheap cost, compact proton accelerators equipped with rotational gantries. The implementation of pencil beam scanning should also make treatment planning and delivery much easier and faster than conventional approaches. Until now, approximately 100,000 patients have been treated with protons worldwide. Due to more complex technological and biological challenges, light ion therapy - mainly carbon ions - has developed at a lower pace, except in Japan where most of the 15,000 treated patients have been enrolled. Current indications for protons include firstly, locally aggressive tumours non or incompletely resected, that are located close to critical normal structures: ocular melanomas, skull base and spinal canal low grade sarcomas, selected ENT carcinomas (like adenoid cystic); secondly, improvement of tolerance to radiations: delayed, mainly in paediatric malignancies, due to the exquisite sensitivity of organs under development (including to carcinogenesis); immediate, on bone marrow, mucosae… mainly in concomitant radiation-chemotherapy interactions (tested in esophagus, and lung). Most promising indications for carbon ions include inoperable highly radioresistant primaries, such as mucosal melanomas, high grade bone and soft part sarcomas, and pancreatic carcinomas. Altered fractionations are also of interests that could translate in clinical and economical benefits. Controversies have risen whether more common indications, like prostate, should also be explored.

    Eustachian tube dysfunction is closely related to the development of otitis media and result from several factors including inflammation within the nasal cavity and nasopharynx, adenoid hypertrophy, cleft palate and nasopharyngeal carcinoma. To some extent, eustachian tube dysfunction may be related to weakness of the paratubal muscles, such as the tensor veli palatini and levator veli palatini muscles. The aim of the study is to find out myogenic factors in eustachian tube dysfunction using electromyography (EMG), and to evaluate the clinical feasibility of EMG. Ten patients with unilateral eustachian tube dysfunction were included in this study. The healthy side of each patient was used as a control. EMG tests on paratubal muscles were conducted under the view of a 30° endoscope or fiberoptic laryngoscope. EMG on the tensor veli palatini showed decreased amplitudes on the affected side in one patient during phonation. EMG on the levator veli palatini showed decreased amplitudes on the affected side in two patients during both deglutition and phonation, one patient during phonation only, and two patients during deglutition only. The only patient who had decreased amplitude on EMG of the tensor veli palatini also had decreased amplitude on EMG of the levator veli palatini. In conclusion, although it is generally accepted that the tensor veli palatini plays a major role in opening the eustachian tube, reduced activity of the levator veli palatini may be related to eustachian tube dysfunction. When assessing eustachian tube function, EMG is useful for evaluating myogenic factors.

    Caveolin-1, a tyrosine-phosphorylated protein, is supposed to have different regulatory roles as promoter or suppressor in many human cancers. However, no published study concerned its expression in benign and malignant salivary gland tumors. The aim of this study was to evaluate and compare the expression of Cav-1 in the most common benign and malignant salivary gland tumors and evaluate its correlation with proliferation activity. In this cross-sectional retrospective study, immunohistochemical expression of caveolin-1 and Ki67 were evaluated in 49 samples, including 11 normal salivary glands, 15 cases of pleomorphic adenoma (PA), 13 adenoid cystic carcinomas (AdCC), and 10 mucoepidermoid carcinomas (MEC). The expression of Cav-1 was seen in 18 % of normal salivary glands and 85 % of tumors. The immunoreaction in the tumors was significantly higher than normal tissues (P = 0.001), but the difference between benign and malignant tumors was not significant (P = 0.07). Expression of Cav-1 was correlated with Ki67 labeling index in PAs, but not in malignant tumors. Cav-1 expression was not in association with tumor size and stage. Overexpression of Cav-1 was found in salivary gland tumors in comparison with normal tissues, but no significant difference was observed between benign and malignant tumors. Cav-1 was inversely correlated with proliferation in PA. Therefore, this marker may participate in tumorigenesis of salivary gland tumors and may be a potential biomarker for cancer treatments.

    KIT (CD117, c-kit) is a receptor tyrosine kinase involved in the tumorigenesis of several neoplasms. KIT is expressed by the secretory cells of normal sweat glands. We studied the KIT expression and KIT mutational status in various benign and malignant tumors of eccrine and apocrine glands. We included a total of 108 cases comprising 10 benign and 6 malignant sweat gland tumors, and KIT expression was immunohistochemically detected (positive rate): 10 syringomas (0%), 8 poromas (25%), 20 mixed tumors (40%), 21 spiradenomas (43%), 1 cylindroma (0%), 5 hidradenomas (40%), 7 syringocystadenoma papilliferum cases (0%), 1 papillary hidradenoma (100%), 2 tubulopapillary hidradenomas (50%), 8 hidrocystomas (29%), 2 adenoid cystic carcinomas (100%), 5 porocarcinomas (20%), 6 apocrine carcinomas (33%), 10 extramammary Paget diseases (30%), 1 spiradenocarcinoma (100%), and 1 syringocystadenocarcinoma papilliferum (0%). Most KIT-positive cells were luminal cells, arising from glandular structures. We performed polymerase chain reaction-single-strand conformation polymorphism for detecting KIT mutational status. All cases showed no mutations at hot spots for KIT (exons 9, 11, 13, and 17). KIT mutation does not seem to be mechanism for KIT expression, but the expression may be from native sweat glands.

    Full Text Available Objective: This study was designed to compare the pattern of obstructive sleep apnea (OSA among obese and nonobese subjects regarding clinical and polysomnographic data obtained for a polysomnographic study. Methods: A cross-sectional retrospective descriptive study was conducted by analyzing polysomnographic data in 112 consecutive patients underwent a sleep study at our sleep laboratory from January 2009 to July 2010. Out of them, 81 were diagnosed to have OSA (apnea-hypopnoea Index ≥5. These patients were classified in two groups with body mass index (BMI 0.001. The minimal oxygen saturation was lower in the obese than the nonobese group (68.5 ± 13.00 vs. 80.3 ± 7.40, P0.001 and was well below 90% in both groups. Overall, the OSA in nonobese patients was mild-to-moderate as compared to that of the obese and no significant differences were observed between them as regard to age, gender, mean neck circumference, excessive daytime sleepiness, adenoid or tonsillar enlargement, smoking, and remaining polysomnographic parameters. Conclusion: Obstructive sleep apnea can occur in nonobese persons though with less severity as compared to obese leading to a concept that OSA is not restricted to obese persons only and there is a high demand of its awareness regarding evaluation, diagnosis, and management in such individuals.

    A complex lymphoepithelial gland is a constant feature in the larynx of Atlantic bottlenose dolphins, Tursiops truncatus, based on study of 56 animals. Larynges were removed from fresh, non-decomposed beach-stranded animals for gross examination and histological sampling. A large lymphoepithelial gland occurs in the rostro-ventral mucosa of the larynx, overlying the cricoid cartilage. It presents as a well-defined, elevated, and heavily trabeculated area. Histological examination reveals a pseudostratified columnar epithelium which branches into the underlying submucosa. The epithelial-lined folds and crypts thus formed are surrounded by aggregations of lymphocytes, which infiltrate this epithelium. Mucous glands are often associated with these lymphoid aggregations. The histological appearance of the laryngeal gland is remarkably similar to the palatine, or dorsal oropharyngeal tonsils, of T. truncatus. It may be analogous to the nasopharyngeal adenoid of terrestrial animals. Age-related involution of the laryngeal gland is not as obvious with increasing animal age (or length) as it is in other mucosa-associated lymphoid tissue. The distribution of this gland among cetaceans is not yet known. We have observed it in individuals of every species we have studied, including Lagenodelphis hosei, Stenella coeruleoalba, Stenella attenuata, Globicephala macrorhynchus, Steno bredanensis, Physeter catodon, Pseudorca crassidens, Mesoplodon europaeus, and Kogia breviceps.

    Acute otitis media and otitis media with effusion (OME) are the main causes of hearing impairment in children which require proper treatment, mainly antibiotic therapy. Patients whom were appropriate candidates for adenoidectomy were divided into two groups regarding the presence of middle ear effusion. Adenoid tissue specimens were cultured in both groups and the bacterial flora and anti-microbial resistance pattern were determined. 72 patients were studied, 42 % had OME while 58 % did not. The following bacteria were isolated and cultured from both groups with no meaningful difference in prevalence: Streptococcus viridans (p = 0.265), Staphylococcus aureus (p = 0.72), H. influenza (p = 0.806), Entrococcus. spp (0.391), Streptococcus pneumonia (p = 0.391), nonhemolytic Streptococcus (p = 0.230). Bacterial sensitivity was similar for Amoxicillin-clavulanate (p = 0.935), Amoxicillin (p = 0.935), Cephalexin (p = 0.806), Cefixime (p = 0.391) and Azithromycin in both groups. The two groups showed no meaningful difference considering the bacterial flora of nasopharynx and their sensitivity. Bacteria in both groups were sensitive to Amoxicillin and Amoxicillin-clavulanate and resistant to Azithromycin, Cefixime and Cephalexin. PMID:25929414

    With the aim of assessing a possible increase in tumour rates due to damage to the respiratory tissues of the upper respiratory tract the study, based on the inhalation effects found in rats, investigated into the cancerogenic effects of very thin glass fibers and crocidolite as well as into the combined effects of glass fibers and sulfur dioxide. Although there were no significantly higher tumour rates found with any of the fibers applied, high rates of bronchio-alveolar hyperplasies (74%), plate epithel metaplasy in one case, and adenoidal cancer after crocidolite treatments were found to be indicative of the tendency of crocidolite to induce neoplasms. After i.p. injections of 0.5 mg tumour rates were 17% in the case of JM 104/475 glass fibers and 55% in the case of crocidolite of South African origin. The parallelism of the diagnoses of humans exposed to crocidolite and of i.p. injections in rats shows the validity of the i.p. model. Valuable results were obtained with regard to the persistence of glass fibers in lungs after inhalation.

    1988-07-01

    In the present study osteoradionecrosis which had developed after radiotherapy for malignant tumor was studied clinically and therapeutically and the following results were obtained. 1. The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5. As the method of treatment, sequestrectomy was performed in 14 of 19 cases of the limited area type and 4 of 11 cases of the wide range type and excision of the jaws in 4 cases. 6. Hyperbaric oxygen therapy was carried out in 3 cases and had good effect. (J.P.N.).

    Purpose: To study MR findings for clues to the diagnosis of lingual thyroid. Material and methods: MR findings and clinical and scintigraphic data of 5 cases of lingual thyroid were reviewed and the MR findings were compared to those of 16 cases of other submucosal lesions in the base of the tongue. Results: Four of the 5 patients with lingual thyroid were women and all had hypothyroidism. MR imaging depicted lingual thyroid in the midline in the base of the tongue (n=5) and additional ectopic thyroid glands in the floor of the mouth (n=2) or between the right and left sternohyoid muscles (n=1). Ectopic thyroid glands appeared isointense or hyperintense relative to muscle tissue on T1-weighted images and showed slight or fair contrast enhancement. All glands had low to intermediate T2 signal, which was also seen in 1 case of non-Hodgkin's lymphoma and 1 case of adenoid cystic carcinoma. All ectopic thyroid glands had well-defined margins, whereas malignant tumors tended to have ill-defined margins and to invade the surrounding structures. All but the 5 cases of lingual thyroid had an MR-demonstrable thyroid gland in the normal cervical position. Conclusion: A well-defined mass of low-intermediate T2 signal in the midline base of the tongue, neither with invasive tendency nor with a cervical thyroid gland in the normal site on MR imaging, may strongly indicate lingual thyroid.

    Ninety three patients with obstructing tracheobronchial tumors were treated with Neodymium: Yttrium - Aluminum - Garnet (Nd:YAG) laser photocoagulation over a period of six years. There were sixty seven Males and 26 Females with a mean age of 44.3 years (range 6- 79 years). 21 benign and 72 malignant lesions were treated with a total 212 sessions of laser photocoagulation (mean 2.4 sessions). The anatomical distribution of lesions were as follows; larynx 9 (three benign and 6 malignant) trachea 39 (27 benign and 12 malignant) left main bronchus 27 (14 malignant) right main bronchus 24 (14 malignant) and vocal cords - 9 (three malignant). There were 21 patients with squamous cell carcinoma, two adenocarcinomas, one adenoid cystic carcinoma, 7 cases of locally infiltrating tumors from thyroid and esophagus, 6 cases of carcinoid tumor and 16 benign lesions. Twenty one patients had a tracheostomy tube in place when treatment was started. Eighteen of the 21 patients with tracheostomy were weaned off the tube in a mean of 5.5 days from the start of treatment. Lumen was restored in 31 (79.4%) patients. In the other eight (20.6%), lumen was achieved, but not sustained. Complications included bleeding in three cases which were managed conservatively, two cases of pneumothorax, and four cases of bronchospasm. There were six deaths during the follow up but none attributable to the procedure. Laser photocoagulation offered effective treatment in the majority of patients with obstructing tracheobronchial tumors, with acceptable morbidity.

    CT and MR findings of nine cases with intra temporal facial nerve neuromas were described and compared with CT findings of 3 cases with facial nerve palsy and facial nerve canal erosion which may mimic facial nerve neuroma. The tympanic segment of the facial nerve was involved in 8 cases, mastoid segment in 7 cases and labyrinthine segment in 5 cases. The lesions were easily diagnosed with high resolution CT with bone algorithms by showing the expansion of bony structures along the course of the facial nerves. In 4 cases with large vertical segment tumors, extensive destruction of mastoid air cells and external auditory canals posed difficulty in making a diagnosis. Two out of 5 cases with labyrinthine segment involvement were presented as middle cranial fossa masses. MRI with enhancement was performed in 4 cases and was useful in characterizing the lesion as a tumor with its superior sensitivity to enhancement. Three cases of facial neuroma-mimicking lesion including post-inflammatory peri neural thickening, peri neural extension from parotid adenoid cystic carcinoma, and congenita; cholesteatoma showed irregular erosion or mild expansion of the facial nerve canal which may be helpful for differential diagnosis from neuromas.

    Full Text Available Benign or malignant tumors of mouth and oropharyngeal region often result in the maxillofacial defects. The acquired maxillectomy defects results in the impairment of speech, mastication, swallowing and facial esthetics. The Prosthodontist plays a significant role in the rehabilitation of the acquired maxillectomy defects with the special emphasis to the reduction of the weight of the prosthesis and thereby enhancing the retention and stability. The weight of the obturator can cause a dislodging force. It must therefore be as light as possible. A suitable technique of fabrication should be selected to achieve this. This case report describes the fabrication of a hollow bulb obturator for a hemi- maxillectomy patient (Aramany’s class 1 defect who had undergone wide excision and alveolar resection squeal of management of adenoid cystic carcinoma of the right palate. This article describes the step by step clinical and laboratory procedure involved in the rehabilitation of a hemimaxillectoy dentate patients using obturator lined with soft liner to restore the functions such as esthetics, mastication, deglutition and speech

    This is an autopsy report of multiple primary cancers observed in a patient who had clinically been diagnosed as chronic arsenic poisoning. An 88-year-old man, non-smoker, had worked in an arsenic mine for 6 years from the age of 47. He had undergone operations for Bowen's disease and gastric cancer at ages 80 and 86, respectively. At autopsy, squamous cell carcinoma of the lung and a polypoid lesion in the piriform recess were found. Furthermore, microscopic examination revealed latent prostatic adenocarcinoma and oncocytoma in the kidney. The polypoid lesion of the piriform recess appeared to originate from the duct of the minor salivary gland in the pharynx, showing an adenoid cystic carcinoma-like pattern with squamous cell carcinoma in part. The cause of death was thought to be respiratory failure due to bronchopneumonia and pulmonary edema as well as hydrothorax, and chronic heart failure following ischemic heart disease. Bowen's disease was followed by four internal malignant tumors, even though the etiological relation between these cancers and arsenic is not clear.

    Epithelial cell adhesion molecule (EpCAM) is the epithelial-specific molecule expressed on various epithelial cell types. The function of EpCAM involves cellular adhesion, proliferation, and signaling in both normal tissues and cancers. The purposes of this study were to investigate the EpCAM expression in salivary gland neoplasms and examine its relationship with pathologic characteristics. Forty-two cases of salivary gland neoplasms, including 20 mucoepidermoid carcinomas (MECs), 11 adenoid cystic carcinomas (ACCs), 9 pleomorphic adenomas (PAs), and 2 polymorphous low-grade adenocarcinomas (PLGAs) were enrolled. Epithelial cell adhesion molecule expression was analyzed immunohistochemically using MOC-31 and BerEP4 antibodies. Results showed that the majority of MECs and all PLGAs showed EpCAM expression in more than 50% of neoplastic cells, whereas most PAs and ACCs did not express this protein. In MECs, most EpCAM-positive neoplastic cells were clear cells, glandular epithelial cells, and intermediate cells, whereas squamous cells and mucous cells were largely negative. The expression was limited to ductal epithelium in EpCAM-positive PAs and ACCs. The decreased EpCAM expression in MECs was significantly associated with microscopically diminished cystic components, the presence of small nest invasion at invasive front, cellular anaplasia, vascular invasion, and high pathologic grade. These data suggested that EpCAM showed different expression pattern among salivary gland neoplasms and in different grades of MECs. PMID:27649957

    We conducted a retrospective case-series review to identify the various diagnoses of neoplasms of the nasal cavity and paranasal sinuses in a pediatric population. Our study group was made up of 54 children-23 boys and 31 girls, aged 8 months to 16 years (mean: 9 yr). All patients had been diagnosed with a tumor of the nasal cavity or paranasal sinuses between Jan. 1, 1955, and Dec. 31, 1999, at one of four university-based, tertiary care referral centers. We compiled data on tumoral characteristics (location, size, and histopathology), morbidity and mortality, and rates of recurrence. Lesions included adnexal neoplasm, ameloblastic fibro-odontoma, basal cell carcinoma, benign fibrous histiocytoma, blue nevus, chondrosarcoma, compound nevus, epithelioma adenoides cysticum, esthesioneuroblastoma, Ewing sarcoma, fibrosarcoma, giant cell granuloma, granulocytic sarcoma, hemangioma, hemangiopericytoma, Langerhans cell histiocytosis, lymphangioma, lymphoma, melanoma, neuroblastoma, neurofibroma, ossifying osteofibroma, osteochondroma, osteosarcoma, port wine stain, rhabdomyosarcoma, Spitz nevus, and xanthogranuloma. To the best of our knowledge, this is the largest such study of its kind to date. We believe that the large size of this study and the data on disease incidence will allow clinicians to be better informed of the differential diagnosis of neoplasms of the nasal cavity and paranasal sinuses in the pediatric population.

    A twenty eight-year-old male presented with a two week history of dyspnea, cough, hemoptysis, chest pain, and fever 38-39°C. He also complained of loss of appetite, general weakness and left leg pain for two months preceding admission. He was referred with suspicion of lung tumor to our institution. Chest X-ray showed almost total atelectasis of the right lung with compensatory overinflation of the contralateral lung. Using computed tomography (CT), a lesion of diameter of 19.3 x 14.1 x 19.1 cm in the right lung, pleuritis, Th3 osteolysis, and compensatory overinflation of the left lung was seen. Bronchoscopy revealed a total obstruction of the right main bronchus due to submucosal infiltration and compression of the right main bronchus with negative histology of bronchial biopsy specimens. Transthoracic fine needle aspiration revealed celullae suspectae probabiliter neoplasmaticae suggesting tumor fusocellularis. USG of the abdomen revealed liver with numerous heterogeneous, solid areas hypo- and hyperechogenic, some of them with features of liquid or the disintegration up to diameter of 74 mm. Subsequent fine needle aspirations of the thorax and liver revealed fibrolamellar hepatocarcinoma and carcinoma adenoides of the lung. Patient underwent chemotherapy with 5-FU/DDP/VCR with no response. This report presents a case of a rare lung metastasis from FL-HCC.

    Familial cylindromatosis (turban tumor syndrome; Brooke-Spiegler syndrome) (OMIM numbers 123850, 132700, 313100, and 605041) is a rare autosomal dominantly inherited tumor syndrome. The disorder can present with cutaneous adnexal tumors such as cylindromas, trichoepitheliomas, and spiradenomas, and tumors preferably develop in hairy areas of the body such as head and neck. In affected families, mutations have been demonstrated in the CYLD gene located on chromosome 16q12-13 and reveal the characteristic attributes of a tumor suppressor. Here, we studied familial cylindromatosis in a multigeneration family of German origin. Clinically, some individuals only revealed discrete small skin-colored tumors localized in the nasolabial region whereas one family member showed expansion of multiple big tumors on the trunk and in a turban-like fashion on the scalp. Histologically, cylindromas as well as epithelioma adenoides cysticum were found. We detected a frameshift mutation in the CYLD gene, designated 2253delG, underlying the disorder and were able to show that a single mutation can result in distinct clinical and histologic expression in familial cylindromatosis. The reasons for different expression patterns of the same genetic defect in this disease remain elusive, however. Identification of mutations in the CYLD gene enable us to rapidly confirm putative diagnoses on the genetic level and to provide affected families with genetic counseling.

    Two trials were conducted to compare the efficacy of currently approved anticoccidials for turkeys against challenge using a field isolate of mixed Eimeria species; E. adenoides, E. gallopavonis, and E. meleagrimitis. Poults in wire-floored cages were fed unmedicated diets from day-old to 3 wk of age. Diets were supplemented with either amprolium (AMP, 125 mg/kg), butynorate (BUT, 375 mg/kg), monensin (MON-60, 60 mg/kg; MON-100, 100 mg/kg), halofuginone (HAL; 3 mg/kg), zoalene (ZOA; 125 mg/kg), or sulfadimethoxine plus ormetoprim (SUL + ORM, 62.5 mg/kg and 37.5 mg/kg, respectively). After 2 days on the test diets, poults were individually weighed and inoculated with sporulated coccidial oocysts from the field isolate. Total fecal collections were obtained for Days 0 to 5 and 6 to 10 to estimate oocyst output. At 10 days postinoculation, the birds were individually weighed and killed to determine severity of intestinal lesions. The HAL and MON were most effective and AMP, ZOA, and SUL + ORM were least effective in maintaining weight and in reducing the severity of intestinal lesions. All the coccidiostats tested reduced oocyst passage, but poults fed HAL produced fewer oocysts. The results demonstrated differences in efficacy among anticoccidials with the more recently approved drugs providing the best protection against coccidiosis.

    Cancers of pranasal sinuses are rare neoplasms in humans. In 2003, in Poland there were 132 new patients diagnosed for this disease. Squamous cell cancer is the most frequent one in this region. Other types of cancer in this region are adenocarcinoma (about 30%), carcinoma adenoides cysticum or neoplasms such as rhabdosarcoma, chondrosarcoma, lymphoma or melanoma malignum. There is a very rare neoplasm as a olfactory neuroblastoma in this localization. Cancer of the paranasal sinuses infiltrates only locoregionally. Metastases to the lymph nodes are seldom--below 30%; this is why elective lymphangiectomy or irradiation are not obligatory treatment in this case. The most important is histopathological verification performed by biopsy. For clinical staging it is obligatory to perform endoscopy, CT or MR examination. The treatment of cancers of paranasal sinuses is always surgery with adjuvant irradiation. The modern radiotherapy techniques provide the possibility to spare healthy tissues and organs at risk. The organs at risk in this localization are optical nerves and chiasm, and parotid glands. The conformal radiotherapy is used most frequently. In case of the tumour being of complex shape and located in the vicinity of the organs at risk the IMRT technique is used. The radiation treatment combined with chemotherapy is applied in cases of not radical surgery in the region of ethmoides sinuses.

    Norton, R A

    1997-01-01

    The pathogenicity of Trichomonas gallinarum (TG) in turkeys and chickens was assessed in a series of four experiments. TG was shown to be resistant to freezing for a period of 1 hr at -20 C; birds administered an emulsion of previously frozen TG were readily infected. Young birds receiving this inoculum were more likely to be infected with TG in both ceca compared with birds administered TG emulsion that had remained at room temperature for the same length of time. In this and other experiments, birds infected with the parasite consistently produced a yellow frothy liquid in the ceca, as well as small raised papulae on the mucosal surface of the ceca. Histologically, the lesions were located in the lamina propria, with openings that extended from the apex of the lesion to the crypts. The lamina propria was consistently infiltrated by lymphocytes and scattered heterophiles. Although TG is likely involved in the pathogenesis of the lesions, the resulting pathology could not be linked definitively to TG alone because inoculation was performed with a cecal contents homogenate containing significant numbers of cecal bacteria. Combined infections of TG and Eimeria adenoides (EA) were also studied. Turkeys administered both parasites were more frequently infected with TG in both ceca compared with those that received TG alone. Ceca infected with TG alone tended to be enlarged and gas filled, whereas those infected with the combination of TG and EA were smaller and usually lacked the yellow frothy liquid contents.

    Hadrontherapy, a type of radiation therapy dealing with heavy charged particles, has become for the past decade one of the most sophisticated and attractive approach in the management of cancer. This is related with major technological innovations that have made available, at a relatively cheap cost, compact proton accelerators equipped with rotational gantries. The implementation of pencil beam scanning should also make treatment planning and delivery much easier and faster than conventional approaches. Until now, approximately 100,000 patients have been treated with protons worldwide. Due to more complex technological and biological challenges, light ion therapy - mainly carbon ions - has developed at a lower pace, except in Japan where most of the 15,000 treated patients have been enrolled. Current indications for protons include firstly, locally aggressive tumours non or incompletely resected, that are located close to critical normal structures: ocular melanomas, skull base and spinal canal low grade sarcomas, selected ENT carcinomas (like adenoid cystic); secondly, improvement of tolerance to radiations: delayed, mainly in paediatric malignancies, due to the exquisite sensitivity of organs under development (including to carcinogenesis); immediate, on bone marrow, mucosae… mainly in concomitant radiation-chemotherapy interactions (tested in esophagus, and lung). Most promising indications for carbon ions include inoperable highly radioresistant primaries, such as mucosal melanomas, high grade bone and soft part sarcomas, and pancreatic carcinomas. Altered fractionations are also of interests that could translate in clinical and economical benefits. Controversies have risen whether more common indications, like prostate, should also be explored. PMID:24007956

  19. High throughput generation and trapping of individual agarose microgel using microfluidic approach

    Microgel is a kind of biocompatible polymeric material, which has been widely used as micro-carriers in materials synthesis, drug delivery and cell biology applications. However, high-throughput generation of individual microgel for on-site analysis in a microdevice still remains a challenge. Here, we presented a simple and stable droplet microfluidic system to realize high-throughput generation and trapping of individual agarose microgels based on the synergetic effect of surface tension and hydrodynamic forces in microchannels and used it for 3-D cell culture in real-time. The established system was mainly composed of droplet generators with flow focusing T-junction and a series of array individual trap structures. The whole process including the independent agarose microgel formation, immobilization in trapping array and gelation in situ via temperature cooling could be realized on the integrated microdevice completely. The performance of this system was demonstrated by successfully encapsulating and culturing adenoid cystic carcinoma (ACCM) cells in the gelated agarose microgels. This established approach is simple, easy to operate, which can not only generate the micro-carriers with different components in parallel, but also monitor the cell behavior in 3D matrix in real-time. It can also be extended for applications in the area of material synthesis and tissue engineering. © 2013 Springer-Verlag Berlin Heidelberg.

    Salivary gland cancers (SGCs) are rare diseases and their treatment depends upon histology, stage and site of origin. Radical surgery is the mainstay of treatment but radiotherapy (RT) plays a key role in both the postoperative and the inoperable setting, as well as in recurrent disease. In the absence of prospective randomized trials, a wide retrospective literature suggests postoperative RT (PORT) in patients with high risk pathological features. SGCs, and adenoid cystic carcinoma (ACC) in particular, are known to be radio-resistant tumors and should therefore respond well to particle beam therapy. Recently, excellent outcome has been reported with radical carbon ion RT (CIRT) in particular for ACC. Both modern photon- and hadron-based treatments are effective and are characterized by a favourable toxicity profile. But it is not clear whether one modality is superior to the other for disease control, due to the differences in patients' selection, techniques, fractionation schedules and outcome measurements among clinical experiences. In this paper, we review the role of photon and particle RT for malignant SGCs, discussing the difference between modalities in terms of biological and technical characteristics. RT dose and target volumes for different histologies (ACC versus non-ACC) have also been taken into consideration. PMID:27394087

    Apoptosis is an evolutionary conserved cellular process that plays an important role during development, but it is also involved in tissue homeostasis and in many diseases. To study the characteristics of suicide gene system of the herpes simplex virus thymidine kinase (HSV-tk) gene in tumor cells and explore the apoptosis phenomena in this system and its effect on the human adenoid cystic carcinoma line ACC-M cell, we detected apoptosis of CD3- (ECFP-CRS-DsRed) and TK-GFP-expressing ACC-M (ACC-M-TK-GFP-CD3) cells induced by acyclovir (ACV) using fluorescence resonance energy transfer (FRET) technique. CD3 is a FRET-based indicator for activity of caspase-3, which is composed of an enhanced cyan fluorescent protein, a caspase-3 sensitive linker, and a red fluorescent protein from Discosoma with efficient maturation property. FRET from ECFP to DsRed could be detected in normal ACC-M-TK-GFP-CD3 cells, and the FRET efficient was remarkably decreased and then disappeared during the cells apoptosis induced by ACV. It was due to the activated caspase-3 cleaved the CD3 fusion protein. In this study, the results suggested that the AVC-induced apoptosis of ACC-M-TK-GFP-CD3 cells was through caspase-3 pathway.

    HSV-tk/GCV system, which is the virus-directed enzyme/prodrug therapy of herpes simplex virus (HSV) thymidine kinase (tk) gene / the anti-viral reagent ganciclovir (GCV), is one of the promising approaches in the rapidly growing area of gene therapy. As gene therapy of cancer such as suicide gene therapy has entered the clinic, another therapy effect which is called 'bystander effect' was reported. Bystander effect can lead to killing of non-transduced tumor cells in the immediate vicinity of GCV-treated HSV-TK-positive cells. Now the magnitude of 'bystander effect' is an essential factor for this anti-tumor approach in vivo. However, the mechanism which HSV-tk/ACV brings "bystander effect" is poorly understood. In this study, we monitor the activation of caspase-3 in HSV-tk/GCV system by a FRET probe CD3, a FRET-based indicator for activity of caspase3, which is composed of an enhanced cyan fluorescent protein, a caspase-sensitive linker, and a red fluorescent protein from Discosoma with efficient maturation property. Through application of CD3 we have visualized the activation of caspase-3 in tk gene positive human adenoid cystic carcinoma (ACC-M) cells but not in bystander effect of HSV-tk/GCV system induced by GCV. This finding provides needed information for understanding the mechanisms by which suicide gene approaches actually kill cancer cells, and may prove to be helpful for the clinical treatment of cancers.

    Cytotoxic gene therapy mediated by gene transfer of the herpes simplex virus thymidine kinase (HSV-tk) gene followed by acyclovir (ACV) treatment has been reported to inhibit malignant tumor growth in a variety of studies. The magnitude of "bystander effect" is an essential factor for this anti-tumor approach in vivo. However, the mechanism by which HSV-tk/ACV brings "bystander effect" is poorly understood. In this report, the plasmid CD3 (ECFP-CRS-DsRed) and TK-GFP were transferred to the human adenoid cystic carcinoma line ACC-M cell line. The CD3-expressing cells apoptosis was monitored using fluorescence resonance energy transfer (FRET) technique. First, CD3 and TK-GFP co-expressing ACC-M cells apoptosis was monitored using FRET technique. The apoptosis was induced by ACV and initiated by caspase3. The FRET efficient was remarkably decreased and then disappeared during cellular apoptosis, which indicated that the TK-GFP expressing ACC-M cells apoptosis, induced by ACV, was via a caspase3-dependent pathway. Secondly, CD3 and TK-GFP mixed expressing ACC-M cells apoptosis, induced by ACV, were monitored using FRET technique. The apoptotic phenomena appeared in the CD3-expressing ACC-M cells. The results show that HSV-tk/ACV system killed ACC-M cells using its bystander effect. These results confirm that HSV-tk/ACV system is potential for cancer gene therapy.

    Full Text Available Introduction: mucopolysaccharidoses known as MPS are a group of hereditary metabolic diseases, caused by the absence or bad functioning of certain lysosomal enzymes necessary for the processing of molecules called glycosaminoglycans (GAGs ormucopolysaccharidos. When the deterioration process of GAGs is altered, a progressiveintralysosomal store of the insufficiently catabolized substrates is produced, whichentails to the clinical manifestations of MPS.Clinical cases: Five cases of MPS are presented. They correspond to five patientswho are natural, resident and proceeding from Cartagena, between 4.5 and 12 yearsof age. Two of them were women and three of them were men. There were not norconsanguinity between their parents, neither important family histories. Two patientshad retard in their psychomotor development. Two had history of respiratory problemssuch as adenoiditis and pneumonia. In the physical exam, all of them had coarse facies.Two had dolichocephaly, one had turricephaly and other had cranial asymmetry. Onlyone patient showed corneal opacity, all patients had short neck and broad hands. Onepatient presented hepatomegaly, two presented scoliosis and one presented kyphosis.Conclusions: Early diagnosis of MPS continues being a challenge for the clinical doctor. The early recognition of symptoms is necessary. Some enzymatic replacement therapiesalready exist to prevent or to mitigate the morbimortality.

    We used a mobile positron emission tomography (PET) scanner positioned within the proton therapy treatment room to study the feasibility of proton range verification with an in-room, stand-alone PET system, and compared with off-line equivalent studies. Two subjects with adenoid cystic carcinoma were enrolled into a pilot study in which in-room PET scans were acquired in list-mode after a routine fractionated treatment session. The list-mode PET data were reconstructed with different time schemes to generate in-room short, in-room long and off-line equivalent (by skipping coincidences from the first 15 min during the list-mode reconstruction) PET images for comparison in activity distribution patterns. A phantom study was followed to evaluate the accuracy of range verification for different reconstruction time schemes quantitatively. The in-room PET has a higher sensitivity compared to the off-line modality so that the PET acquisition time can be greatly reduced from 30 to <5 min. Features in deep-site, soft-tissue regions were better retained with in-room short PET acquisitions because of the collection of {sup 15}O component and lower biological washout. For soft tissue-equivalent material, the distal fall-off edge of an in-room short acquisition is deeper compared to an off-line equivalent scan, indicating a better coverage of the high-dose end of the beam. In-room PET is a promising low cost, high sensitivity modality for the in vivo verification of proton therapy. Better accuracy in Monte Carlo predictions, especially for biological decay modeling, is necessary.

    Full Text Available We have measured total levels of alpha-2-macroglobulin (α2-MG, its immune complexes with IgG (α2-MG-IgG, along with IL-6, IL-8, IL-10, TNFα, lactoferrin (LF and alpha-1-antitrypsin (AT contents in blood sera of children with verified chronic adenoiditis (ChA, pharyngeal tonsil hypertrophy (PhTH, and in sera of healthy children. It was shown, that α2-MG, α2-MG-IgG, AT, IL-10 serum concentrations in ChA and PhTH were significantly increased in comparison with appropriate values in healthy children. Moreover, we have detected significant increase in LF, and slight decrease of IL-6 and IL-8 contents in sera of ChA patients. All general trends of detected changes were similar for both diseases, but some changes proved to be differently expressed. In ChA, however, we found higher levels of circulating α2-MG molecules in circulation, some deficiency in IL-6 and IL-8, and significant abundance of IL-10 and LF at the beginning of ChA, thus resulting into a chronic disorder. In PhTH patients, there was no such remarkable abundance of α2-MG and LF in circulation, and no deficiency in IL-6 and IL-8, but higher levels of damaged α2-MG molecules complexing with IgG, total α2-MG, AT and IL-10 excess may provoke distinct metabolic changes and compensatory proliferation of tissues in this disorder.

    This study was performed to analyze the factors affecting local control in malignant tumors of the parotid gland treated with surgery and postoperative radiation. Twenty-six patients were treated for malignant tumors of the parotid gland from 1986 to 1995 at Department of Therapeutic Radiology. Chonnam University Hospital. Age of the patients ranged from 14 to 72 years (median: 55 years). Histologically 10 patients of mucoepidermoid carcinoma, 7 of squamous cell carcinoma. 4 of acinic cell carcinoma, 4 of adenoid cystic carcinoma and 1 of adenocarcinoma were treated. Total parotidectomy was performd in 15 of 26 patients, superficial in 7, subtotal in 4. Facial nerve was sacrificed in 5 patients. Postoperatively 4 patients had residual disease, 4 had positive resection margin. Radiation was delivered through an ipsilateral wedged pair of photon in 11 patients. High energy electron beam was mixed with photon in 15 patients. Electron beam dose ranged from 900 cGy to 3800 cGy (median: 1760 cGy). Total radiation dose ranged from 5000 cGy to 7560 cGy (median: 6020 cGy). Minimum follow-up period was 2 years. Local control and survival rate were calculated using Kaplan-Meier method. Generalized Wilcoxon test and Cox proportional hazard model were used to test factors affecting local control. Five (19%) of 26 patients had local recurrence. Five year local control rate was 77%. Overall five year survival rate was 70%. Sex, age, tumor size, surgical involvement of cervical lymph node, involvement of resection margin, surgical invasion of nerve, and total dose were analyzed as suggested factors affecting local control rate. Among them patients with tumor size less than 4 cm (p=0.002) and negative resection margin (p= 0.011) were associated with better local control rates in univariate analysis.

    Full Text Available Introduction: The role of sentinel node biopsy has revolutionized breast cancer treatment. This determination reduces the mobility of a complete axillary lymphadenectomy. The aim of our study is to analyze the value of sentinel node in low-grade histological breast tumors, studied with hematoxylin and eosin techniques, Immunohistochemistry, and molecular chain reaction in real-time quantitative polymerase (RT-PCR.Materials and methods: In a pilot study we studied a total of 21 patients with histological diagnosis of mucinous carcinoma, adenoid cystic carcinoma, and medullar carcinoma that underwent the sentinel node technique. Once the lymph node was removed, it was sent to pathology, where it was fragmented and evaluated, using between 25% and 50% of the lymph node for molecular biology laboratory studies.Results: The sentinel nodes studied were 32, corresponding to the 21 patients. Of the 32 lymph nodes analyzed, 29 (90.6% were negative on histopathological examination and the molecular identification, 2 (6.2% were positive in both techniques and 1 (3.125% lymph node was positive with quantitative RT-PCR and negative in histology (H&E, which – subsequently by immunohistochemistry (IHC – was diagnosed as isolated tumor cells (ITC.Conclusion: When comparing the techniques of hematoxylin and eosin, immunohistochemistry, and molecular RT-PCR technique, we found greater sensitivity of molecular techniques; this can reduce the false negative andimprove diagnosis of sentinel node metastases. Patients with low  histological grade carcinomas have high survival rates, less aggressive tumor behavior, and reduced lymph node at diagnosis.

    Use of the herpes simplex virus thymidine kinase gene/ganciclovir (HSV-tk/GCV) system is one of the promising approaches in the rapidly growing area of gene therapy. The "bystander effect," a phenomenon in which HSV-tk+ cells exposed to GCV are toxic to adjacent HSV-tk- cells, was reported to play an important role in suicide gene therapy. However, the mechanism by which HSV-tk/GCV induces the bystander effect is poorly understood. We monitored the activation of caspase-3 in living cells induced by the HSV-tk/GCV system using a genetically encoded fluorescence resonance energy transfer (FRET) probe CD3, , a caspase-3 recognition site fused with a cyan fluorescent protien (CFP) and a red fluorescent protein (DsRed) which we reported and named in a previous paper. Fluorescence protein (FP)-based multicolor cellular labeling, combined with the multichannel fluorescence imaging and FRET imaging techniques, provides a novel and improved approach to directly determine whether the activation of caspase-3 involved in the HSV-tk/GCV system induces cell apoptosis in tk gene-expressing cells and their neighboring cells. FRET ratio images of CD3, and fluorescence images of the fusion protein of thymidine kinase linked with green fluorescent protein (TK-GFP), indicated that HSV-tk/GCV system-induced apoptosis in human adenoid cystic carcinoma (ACC-M) cells was via a caspase-3 pathway, and the activation of caspase-3 was not involved in the bystander effect of HSV-tk/GCV system.

    Tumours arising from oral minor salivary glands may exhibit an overlap of clinical and morphological features that may produce diagnostic and therapeutic dilemmas. The aim of this study is to asses the value of fine needle aspiration cytology (FNAC) in differentiation of benign and malignant tumours and to render a specific diagnosis. We evaluated the team work of surgeon and cytologist to improve diagnostic accuracy. Two steps are important for accuracy: sampling aspirate that should be done together by surgeon and cytologist and cytological microscopic analysis of the smears that should be performed by an experienced cytologist. The study included 132 patients with intraoral minor salivary gland tumours between 2002 and 2011. Adequate material was obtained from 121 (91.7%) patients. FNAC was usually performed by cytologist in a team with maxillofacial surgeon at cytology department that is more convenient for preparing the samples and especially for ROSE procedure (rapid-on site evaluation) of smears. In such a way the cytologist checked the adequacy of samples and decided whether some ancillary techniques should be used and therefore repeat FNAC. A total of 82 patients underwent surgery, 40 with malignant and 42 with benign tumours. Preoperative cytological diagnoses were compared with histopathological ones using histopathology as a gold standard. The most common benign tumour was pleomorphic adenoma and among malignant tumours adenoid cystic carcinoma. The most commonly affected site was the palate. The team work of surgeon and cytologist achieved specificity of 95.1%, sensitivity of 97.6% and diagnostic accuracy of 96.3%. We can conclude that although subclassification of some tumour types of salivary glands remains poor, FNAC is invaluable in patient triage and therefore should be considered in the first line investigations of these lesions by the cytologist and surgeon.

    Full Text Available Oral breathing is a respiratory dysfunction that affects approximately 10-15% of child population. It is responsable of local effects and systemic effects, both immediate and long-term. They affect the growth of the subject and his physical health in many ways: pediatric, psycho-behavioral and cognitive. The etiology is multifactorial. It’s important the establishment of a vicious circle involving more areas and it is essential to stop it as soon as possible. In order to correct this anomaly, the pediatric dentist must be able to make a correct diagnosis to treat early the disfunction and to avoid the onset of cascade mechanisms. Who plays a central role is the pediatrician who first and frequently come into contact with little patients. He can identify the anomalies, and therefore collaborate with other specialists, including the dentist. The key aspect that guides us in the diagnosis, and allows us to identify the oral respirator, is the “adenoid facies”. The purpose of the study is to highlight the importance and benefits of an early and multidisciplinary intervention (pediatric, orthopedic-orthodontic-functional. A sample of 20 patients was selected with the following inclusion criteria: mouth breathing, transverse discrepancy > 4 mm, early mixed dentition, central and lateral permenent incisors, overjet increased, lip and nasal incompetence, snoring and/or sleep apnea episodes. The protocol of intervention includes the use of the following devices and procedures: a maxillary rapid expander (to correct the transverse discrepancy, to increase the amplitude of the upper respiratory airway and to reduce nasal resistances tract in association with myo-functional devices (nasal stimulator and oral obturator. They allow the reconstruction of a physiological balance between the perioral musculature and tongue, the acquisition of nasal and lips competence and the reduction of overjet. This protocol speeds up and stabilizes the results. The

For repeated tonsil inflammation and nocturnal sleep apnea in children with OSAHS, tonsillectomy and adenoidectomy is the most effective treatment. But children s postoperative immune function remain in dispute, this review focuses on immunologic function change and influence in the OSAHS children after tonsillectomy and adenoidectomy, according to the existing research results can be confirmed. The immune parameters in OSAHS children who had tonsillectomy and adenoidectomy will vary differently after a short period of several, considering these manifestations are the stress response after operation, and its long-term immune parameters can recover to the normal level. Thus, the postoperative immune function of OSAHS with tonsillitis in children after the adenoid and tonsil resection has no negative effects, providing theory basis for clinicians treatment for clinicians to parents of children with answers to questions provide ihe theory basis.

    SUMMARY Our aim was to define typical magnetic resonance (MRI) findings in malignant and benign parotid tumours. This study is based on retrospective evaluation of pre-surgical MRI of 94 patients with parotid gland tumours. Histology results were available for all tumours. There were 69 cases of benign (73%) and 25 cases of malignant (27%) tumours, including 44 pleomorphic adenomas, 18 Warthin's tumours, 7 various benign tumours, 6 squamous cell carcinomas, 3 carcinoma ex pleomorphic adenomas, 2 mucoepidermoid carcinomas, 1 adenoid cystic carcinoma and 13 various malignant tumours. The following MRI parameters were evaluated: shape, site, size, margins, signal intensity (SI) on T1w and T2w images, contrast enhancement, signal of cystic content, presence or absence of a capsule, perineural spread, extraglandular growth pattern and cervical adenopathy. Statistical analysis was performed to identify the MRI findings most suggestive of malignancy, and to define the most typical MRI pattern of the most common histologies. Ill-defined margins (p < 0.001), adenopathies (p < 0.001) and infiltrative grown pattern (p < 0.001) were significantly predictive of malignancy. Typical findings of pleomorphic adenoma included hyperintensity on T2w images (p = 0.02), strong contrast enhancement (p < 0.001) and lobulated shape (p = 0.04). Typical findings of Warthin's tumour included hyperintense components on T1w images (p < 0.001), location in the parotid inferior process (p < 0.001) and mild or incomplete contrast enhancement (p = 0.01). SI on T1w and T2w images and contrast enhancement enables differential diagnosis between pleomorphic adenoma and Warthin's tumour. PMID:26824912

    Purpose: In this retrospective investigation, the outcome and toxicity after reirradiation with concurrent cetuximab immunotherapy of recurrent head and neck cancer (HNC) in patients who had contraindications to platinum-based chemotherapy were analyzed. Materials and Methods: Ten patients with locally advanced recurrent HNC were retrospectively evaluated. In 9 cases, histology was squamous cell carcinoma, in one case adenoid cystic carcinoma. External beam radiotherapy was part of the initial treatment in all cases. Reirradiation was carried out using step-and-shoot intensity-modulated radiotherapy (IMRT) with a median dose of 50.4 Gy. Cetuximab was applied as loading dose (400 mg/m{sup 2}) 1 week prior to reirradiation and then weekly concurrently with radiotherapy (250 mg/m{sup 2}). Results: The median overall survival time after initiation of reirradiation was 7 months; the 1-year overall survival (OS) rate was 40%. Local failure was found in 3 patients, resulting in a 1-year local control (LC) rate of 61%. The 1-year locoregional control (LRC) rate was 44%, while the 1-year distant metastasis-free survival (DMFS) was 75%. Acute hematological toxicity was not observed in the group. Severe acute toxicity included one fatal infield arterial bleeding and one flap necrosis. Severe late toxicities were noted in 2 patients: fibrosis of the temporomandibular joint in 1 patient and stenosis of the cervical esophagus in another. Conclusions: IMRT reirradiation with concurrent cetuximab immunotherapy in recurrent HNC is feasible with acceptable acute toxicity. Further investigations are necessary to determine the clinical role of this therapy concept. (orig.)

  8. Heavy charged particle therapy

    International Nuclear Information System (INIS)

    A pilot study of heavy charged particles with heavy ion medical accelerator in Chiba (HIMAC) for advanced H and N cancer has been carried out from June 1994 at National Institute of Radiological Sciences (NIRS). As of the beginning of August 1994, three patients were treated by 290 MeV carbon ions. The patients had adenocarcinoma of the cheek mucosa, squamous cell carcinoma of the ethmoid sinus and adenoid cystic carcinoma of the sublingual gland. Patients were immobilized by individual head coach and thermosplint facial shell. Individual collimators and bolus were also prepared for each ports. Dose fractionation for the initial pilot study group was 16.2 GyE/18 fractions/6 weeks, which would be equivalent to standard fractionation of 60.0 Gy/30 fractions/6 weeks with photons. This dose fractionation was considered to be 20% lesser than 75 GyE/37.5 fractions/7.5 weeks, which is estimated to be maximum tolerance dose for advanced H and N cancers. HIMAC worked well and there was no major trouble causing any treatment delay. Acute skin reactions of 3 patients were 2 cases of bright erythema with patchy moist desquamation and one of dull erythema, which were evaluated as equivalent reaction with irradiated dose. Acute mucosa reactions appeared to have lesser reaction than predicted mucositis. Tumor reactions of three patients were partial reaction (PR) at the end of treatment and nearly complete remission (CR) after 6 months of treatment. From October 1994, we started to treat patients with advanced H and N cancer with 10% high dose than previous dose. And new candidates of pilot study with non small cell lung cancer, brain tumor and carcinoma of the tongue were entered into pilot study. At the end of February 1995, a total of 21 patients were treated by carbon ions. (J.P.N.)

    Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult to interpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases of histologically confirmed primary lung cancer from January 1974 to April 1982 at Seoul National University. The results are as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex radio was 3.8 : 1 and there was no sex difference in Adenocarcinoma. 2. Distribution of histologic types of primary lung cancers as follows; Squamous cell carcinoma 50.6%, Small cell carcinoma 22.5%, Large cell carcinoma 9.3%, Bronchogenic adeno carcinoma 10.5%, Bronchioloalveolar cell carcinoma 1.9%, Adenosquamous carcinoma 0.6%, Carcinoid tumor 0.3%, Adenoid cystic carcinoma 0.3%. 3. Radiologic findings by histologic types are follows; a) Squamous cell carcinoma commonly present as collapse (51.8%), peripheral mass (40.8%), pneumonitis (37.2%), hilar involvement (34.8%), and in single abnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement (78.1%), mediastinal widening or mass (53.4%) and in single abnormality, hilar involvement (58.3%). c) Large cell carcinoma commonly present as hilar involvement (50%), pneumonia (46.7%), collapse (40%), peripheral mass (36.7%) and in single abnormality, large peripheral mass (33.3%). d) Bronchogenic adenocarcinoma commonly present as peripheral mass (44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass (50%). e) Solitary peripheral mass commonly present as lobulation (48%) and spiculated margin (51%), but no specific findings by histologic types. Cavitary formation was most common in Squamous cell carcinoma.

    Salivary gland tumors are relatively rare and morphologically diverse and heterogeneous tumors; therefore, histogenesis-based tumor markers are sorely needed to aid in diagnosing and determining the cell type of origin. SRY-related HMG-box 10 (SOX10) protein is a transcription factor known to be crucial in the specification of the neural crest and maintenance of Schwann cells and melanocytes. In addition, positive expression has also been implicated in the major salivary gland. Here, we examined SOX10 expression in various salivary gland tumors to correlate this expression with myoepithelial markers. Overall, 76 malignant and 14 benign tumors were examined. SOX10 expression clearly delineated two distinct subtypes of human salivary gland tumors; acinic cell carcinomas, adenoid cystic carcinomas, epithelial-myoepithelial carcinomas, myoepithelial carcinomas, and pleomorphic adenomas, including the pleomorphic adenoma component of carcinoma, were SOX10 positive, while salivary duct carcinomas, mucoepidermoid carcinomas, an oncocytic carcinoma, Oncocytomas, and Warthin tumors were SOX10 negative. Also, SOX10 was expressed in solid-type or non-specific morphology salivary gland tumors, but was not expressed in poorly differentiated squamous cell carcinomas. In normal human salivary gland tissue, SOX10 expression was specific to the nuclei of acini and both luminal and abluminal cells of intercalated ducts but not in other sites. Moreover, the murine model suggested that SOX10 continued to be expressed from the developmental stage to adulthood in the acinar and both luminal and abluminal intercalated ducts in the major salivary gland. Thus, SOX10 is a novel marker for diagnosing and understanding the histogenesis of salivary gland tumors. PMID:23558573

    AIM: To develop orthotopic gastric cancer mouse models from different cell lines and characterize the tumor features to assist further in preclinical trials and clinical treatment strategies. METHODS: Human gastric cancer SGC-7901 and BGC- 823 cell suspensions were injected subcutaneously into nude mice to develop solid tumors, and tumor tissue pieces were then implanted under the serous coat of the stomach. An autopsy was performed on all animals of the SGC-7901 and BGC-823 models to observe the primary tumor growth and metastases using pathological and immunohistochemical methods. RESULTS: Both models showed large tumors in situ resulting in pressure and infiltration of the adjacent organs. The gastric cavity became smaller, along with stenosis of the cardia or pylorus. There were biological and statistical differences between the two models. The metastasis rate in involved organs (lymph nodes, kidney, spleen, testis) was significantly higher in the BGC-823 model compared to the SGC-7901 model (P < 0.05 or P < 0.01). The median survival of the BGC-823 model was shorter than that of SGC-7901 (23 d vs 84 d, P < 0.05). Histopathologically, the primary tumor and metastatic lesions of the two models showed obvious atypia and mucus in the cytoplasm. Compared with the SGC-7901 model, BGC-823 appeared more poorly differentiated (absence of adenoid structure), had a smaller volume, and richer capillary structure. Immunohistochemical staining revealed cytokeratin 20 and epithelial membrane antigen expression was positive in the SGC-7901 tumors, while negative in BGC-823 ones. CONCLUSION: Models using the SGC-7901 and BGC-823 cell lines were established which could function in gastric cancer research on carcinogenesis mechanism and drug discovery. The two models showed different tumor behavior and the latter was more malignant than the former.

    Salivary gland tumors are relatively rare and morphologically diverse and heterogeneous tumors; therefore, histogenesis-based tumor markers are sorely needed to aid in diagnosing and determining the cell type of origin. SRY-related HMG-box 10 (SOX10) protein is a transcription factor known to be crucial in the specification of the neural crest and maintenance of Schwann cells and melanocytes. In addition, positive expression has also been implicated in the major salivary gland. Here, we examined SOX10 expression in various salivary gland tumors to correlate this expression with myoepithelial markers. Overall, 76 malignant and 14 benign tumors were examined. SOX10 expression clearly delineated two distinct subtypes of human salivary gland tumors; acinic cell carcinomas, adenoid cystic carcinomas, epithelial-myoepithelial carcinomas, myoepithelial carcinomas, and pleomorphic adenomas, including the pleomorphic adenoma component of carcinoma, were SOX10 positive, while salivary duct carcinomas, mucoepidermoid carcinomas, an oncocytic carcinoma, Oncocytomas, and Warthin tumors were SOX10 negative. Also, SOX10 was expressed in solid-type or non-specific morphology salivary gland tumors, but was not expressed in poorly differentiated squamous cell carcinomas. In normal human salivary gland tissue, SOX10 expression was specific to the nuclei of acini and both luminal and abluminal cells of intercalated ducts but not in other sites. Moreover, the murine model suggested that SOX10 continued to be expressed from the developmental stage to adulthood in the acinar and both luminal and abluminal intercalated ducts in the major salivary gland. Thus, SOX10 is a novel marker for diagnosing and understanding the histogenesis of salivary gland tumors.

    Background and aims. Various morphologies are seen in different salivary gland tumorsor within an individual tumor, and the lesions show divers biological behaviors. Experimental results support the hypothesis that increased CrkII proto-oncogene is associated with cytokine-induced tumor initiation and progression by altering cell motility signaling pathway. The aim of this study was to assess the CrkII expression in common malignant salivary gland tumors and pleomorphic ade-noma. Materials and methods. Immunohistochemical analysis of CrkII expression was performed on paraffin blocks of 64 car-cinomas of salivary glands, 10 pleomorphic adenomas, and 10 normal salivary glands. Biopsies were subjected to immu-nostaining with EnVision detection system using monoclonal anti-CrkII. Evaluation of immunoreactivity of CrkII was based on the immunoreaction intensity and percentage of stained tumor cells which were scored semi-quantitatively on a scale with four grades 0 to 3. Kruskal-wallis test and additional Mann-Whitney statistical test were used for analysis of CrkII expression levels. Results. Increased expression of CrkII was seen (P=0.005) in malignant tumors including: mucoepidermoid carcinoma, adenoid cystic carcinoma, and carcinoma ex pleomorphic adenoma, but CrkII expression in acinic cell carcinoma was weak. CrkII expression in pleomorphic adenoma was weak or negative. A weak staining was sparsely seen in normal acinar serous cell. Conclusion. Increased expression of CrkII and its higher intensity of staining in tumors with more aggressive biologic behavior in carcinomas of salivary gland is consistent with a role for this proto-oncogene in salivary gland tumorigenesis and cancer progression.

    International Nuclear Information System (INIS)

    Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult to interpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases of histologically confirmed primary lung cancer from January 1974 to April 1982 at Seoul National University. The results are as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex radio was 3.8 : 1 and there was no sex difference in Adenocarcinoma. 2. Distribution of histologic types of primary lung cancers as follows; Squamous cell carcinoma 50.6%, Small cell carcinoma 22.5%, Large cell carcinoma 9.3%, Bronchogenic adeno carcinoma 10.5%, Bronchioloalveolar cell carcinoma 1.9%, Adenosquamous carcinoma 0.6%, Carcinoid tumor 0.3%, Adenoid cystic carcinoma 0.3%. 3. Radiologic findings by histologic types are follows; a) Squamous cell carcinoma commonly present as collapse (51.8%), peripheral mass (40.8%), pneumonitis (37.2%), hilar involvement (34.8%), and in single abnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement (78.1%), mediastinal widening or mass (53.4%) and in single abnormality, hilar involvement (58.3%). c) Large cell carcinoma commonly present as hilar involvement (50%), pneumonia (46.7%), collapse (40%), peripheral mass (36.7%) and in single abnormality, large peripheral mass (33.3%). d) Bronchogenic adenocarcinoma commonly present as peripheral mass (44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass (50%). e) Solitary peripheral mass commonly present as lobulation (48%) and spiculated margin (51%), but no specific findings by histologic types. Cavitary formation was most common in Squamous cell carcinoma

    Full Text Available El tricoepitelioma, descrito por Brooke en 1892 y también llamado epitelioma adenoideo quístico, es una genodermatosis autosómica dominante originada en el complejo pilosebáceo. Existen dos formas clínicas: la solitaria y la múltiple. Algunos autores recomiendan no tratarlo; sin embargo las lesiones múltiples tienden a deformar la anatomía y la resección parcial presenta recidivas así como cicatrices excesivas y en algunos casos tienen un comportamiento agresivo. Presentamos un caso clínico de tricoepitelioma con deformidad severa de la cara en el que se realizó tratamiento radical con restitución de unidades estéticas mediante colgajos locales. Consideramos que los casos agresivos o deformantes deben ser tratados de forma radical, eliminando todo el espesor de la piel para obtener resultados satisfactorios.Trichoepithelioma, first described by Brooke in 1892, also known as cystic adenoid epithelioma, is a dominantly inherited genodermatosis originated in the follicle bulb. There are two clinical forms, solitary and multiple. Some authors advocate not to treat them, but multiple trichoepithelioma presents a significant cosmetic problem and partial resection can lead to recurrence and excessive scarring, some cases with an aggressive behavior. We present a clinical case of multiple tricoepithelioma with severe deformity of the face in which we realized radical resection with restitution of anatomical units by local flaps. We consider that the multiple cases should be excised with total skin to avoid recurrence and obtain acceptable results.

  18. Obstructive sleep apnoea syndrome in a patient with retrosternal goiter: a case report

    International Nuclear Information System (INIS)

    Full text: Introduction: Obstructive sleep apnoea syndrome (OSAS) is associated with a large number of predisposing factors (obesity, nasal obstruction, adenoid hypertrophy, macroglossia etc.). In addition to these factors goiter and hypothyroidism have been reported to be associated with OSAS. Objectives and tasks: In our case with retrosternal goiter, values of OSAS before and after thyroidectomy were shown. Materials and methods: Seventy-two years old, BMI: 26,8 kg/m2, female patient was admitted our hospital because of complaints to stop breathing during sleep, snoring, morning headache and daytime drowsiness. Results: Thorax CT and ultrasonography of thyroid shown retrosternal goiter and left tracheal deviation. Severe OSAS was diagnosed by polysomnography (PSG). Thyroid function tests were normal. Apneahypopnea index (AHI) was 63,1/h. Patients was performed 7 cm H2O nasal continuous positive airway pressure (gvrnCPAP). AHI was 11,4/h under nCPAP. One month after OSAS diagnosis the patient underwent thyroidectomy operation. Pathological examination was reported as multinodular GOITER. In postoperative period CPAP treatment couldn't continue, because patient was not compliant. In postoperative 8-th weeks, PSG was performed; AHI was 34,8/h. The patient's weight and BMI didn't change. Conclusion: In our case, despite absence of continued CPAP treatment after thyroidectomy, symptoms and PSG values improved partially. As a result of these findings, especially, compression of upper airway and deterioration of venous circulation of patients with large goiter may lead to an increase in OSAS symptoms. During patients with OSAS are treated with CPAP, goiter needs to be investigated

    Long P Le

    Full Text Available Apocrine-eccrine carcinomas are rare and associated with poor prognosis. Currently there is no uniform treatment guideline. Chemotherapeutic drugs that selectively target cancer-promoting pathways may complement conventional therapeutic approaches. However, studies on genetic alterations and EGFR and Her2 status of apocrine-eccrine carcinomas are few in number. In addition, hormonal studies have not been comprehensive and performed only on certain subsets of apocrine-eccrine carcinomas. To investigate whether apocrine-eccrine carcinomas express hormonal receptors or possess activation of oncogenic pathways that can be targeted by available chemotherapeutic agent we performed immunohistochemistry for AR, PR, ER, EGFR, and HER2 expression; fluorescence in situ hybridization (FISH for EGFR and ERBB2 gene amplification; and molecular analyses for recurrent mutations in 15 cancer genes including AKT-1, EGFR, PIK3CA, and TP53 on 54 cases of apocrine-eccrine carcinomas. They include 10 apocrine carcinomas, 7 eccrine carcinomas, 9 aggressive digital papillary adenocarcinomas, 10 hidradenocarcinomas, 11 porocarcinomas, 1 adenoid cystic carcinoma, 4 malignant chondroid syringomas, 1 malignant spiradenoma, and 1 malignant cylindroma. AR, ER, PR, EGFR and HER2 expression was seen in 36% (19/53, 27% (14/51, 16% (8/51, 85% (44/52 and 12% (6/52, respectively. Polysomy or trisomy of EGFR was detected by FISH in 30% (14/46. Mutations of AKT-1, PIK3CA, and TP53 were detected in 1, 3, and 7 cases, respectively (11/47, 23%. Additional investigation regarding the potential treatment of rare cases of apocrine-eccrine carcinomas with PI3K/Akt/mTOR pathway inhibitors, currently in clinical testing, may be of clinical interest.

    Numerous researchers report the interaction between deviant respiratory patterns (airway obstruction) and craniofacial growth. Many of these studies consisted of cephalometric evaluations of children with enlarged adenoids, obstruction turbinates, or other nasal obstructions. Other experimental studies of the airway's influence on growth include studies that have induced nasal obstruction in animals by plugging the external nares. No investigations were found that examined the role of the paranasal sinuses in craniofacial growth by filling a sinus in growing animals. Furthermore, nothing appears in the literature that considers the paranasal sinuses in the oronasopharyngeal functional matrix theory. The purpose of this study was twofold: (1) to determine the effect of decreasing the pneumatization of the maxillary sinus on ultimate craniofacial growth and development, and (2) to determine the effect on future morphology by obturating a growing sinus. New Zealand white weaning rabbits were used as the experimental animals. Unilateral maxillary sinuses were injected in 18 animals--nine animals were injected on the right side and nine on the left. Eight rabbits served as controls: five received left-side and three right-side sham injections. Dorsal view cephalometric radiographs were taken at (1) the start, (2) at three progress intervals, and (3) at the end of the experiment. Dried skull direct measurements also were performed at the conclusion of the experiment. No statistical significance was found when comparing right and left sides within groups or when comparing any measurement between groups. This demonstrated that filling the maxillary sinuses had no effect on craniofacial growth; the sinuses grew normally in all animals.

    Full Text Available Background: Teeth, apart from their physiologic function, play an important role in general appearance of indivduals. Therefore any disorder in their growth and evolution, will cause psychologic, social and even economic problems for the person. This observational cross- sectional study aimed to investigate relationship between dental occlusal patterns and obstructive nasal-upper airway- diseases. Methods: This study was perfromed in schools of No.4 Education at district of Isfahan in educational year 1381-82 between 607 students (277 male, 330 female aged 9-12 years old. Results of accurate ENT and dentistry physical examination were registered and analyzed using SPSS software and Chi-square and Mantel - Hanzel test. Results: With increasing age, The frequency of abnormal occlusal patterns increases (from 45.5% to 68.2% in males and 25.8% to 48.5% in females, p=0.015. The increasing in degree of palatal tonsilar hypertrophy was related to higher frequency of abnormal occlusal patterns (36.7% in +1 tonsilar hypertrophy, and 70% in +4 tonsilar hypertrophy, p=0.02. Also, history of frequent common colds, and history of previous nasal fractures were related with abnormal patterns [58.9% (p=0.032, and 83.4% (p= 0.043%, respectively].Five other parameters including sinusitis, hypertrophy of nasal turbinates, rhinitis, nasal polyposis and nasal septal deviation were not associated with abnormal occlusal patterns (p>0.1. Conclusion: Some of obstructive upper airwacy diseases are related with abnormal dental occlusal patterns. These parameters can be simply diagnosed, treated or prevented. Key words: dental occlusion, malocclusion, obstructive nasal disorders, nasal turbinates, adenoid, rhinitis, tonsillectomy, open mouth breathing

    Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy. PMID:26078091

    Background and aims. Mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. The distribution and significance of mast cells in many tumors have been demonstrated. However, few studies have evaluated mast cell infiltration in salivary gland tumors. In this study, mast cell counts were evaluated in benign and malig-nant salivary gland tumors. Materials and methods. This descriptive and cross-sectional study assessed 30 cases of pleomorphic adenoma, 13 cases of adenoid cystic carcinoma, 7 cases of mucoepidermoid carcinoma (diagnosed on the basis of 2005 WHO classifica-tion), with adequate stroma in peritumoral and intratumoral areas, and 10 cases of normal salivary glands. The samples were stained with 5% diluted Giemsa solution and the average stained cell counts were calculated in 10 random microscopic fields in peri- and intra-tumoral areas. Data were analyzed by t-test and Mann-Whitney and Krusskal-Wallis tests. Results. The average mast cell counts increased in the tumors compared to normal salivary glands. There was no signifi-cant difference between benign and malignant tumors and also between different malignant tumors. Infiltration was signifi-cantly denser in peri-tumoral stroma in both tumoral groups (P = 0.001). Minor salivary glands contained significantly more numerous mast cells. Conclusion. Although mast cell counts increased in benign and malignant salivary gland tumors, there were no signifi-cant differences between the tumoral groups. Further studies are suggested to determine the type of these cells which might be useful in the assessment of biological nature of the tumor and its future treatment modality.

    Objective To determine at the mRNA level whether the MAGE-A1 and -A3 genes are expressedin cancer cell lines from salivary glands and relevant clinical carcinomas, andthus to distinguish cancerous tissues from normal tissues and benign tumors in salivary glands.MethodsThe expression of the MEGE-A1 and MEGE-A3 genes at the mRNA level was determined by reverse transcription and polymerase chain reaction (RT-PCR) in 2 cell lines of human adenoid cyst carcinomas (ACC-2 and ACC-M), in 18 malignant tumors and 9 benign salivary gland tumors, and in 10 samples of normal salivary glandtissues.ResultsBoth MAGE-A1 and -A3 genes were expressed in ACC-2 and ACC-M cell lines. None of the 9 benign tumors or the 10 normal tissue samples of salivary glands expressed the genes. The MAGE-A1 and -A3 genes were expressed in 9 (50%) and 11 (61%) of 18 salivary gland carcinomas, respectively, and at least 1 of the 2 genes was expressed in 14 (78 %) of them. Of the 18 salivary gland carcinomas, 6 low-differentiated carcinomas (33%) expressed both genes, whereas 4 high-differentiated carcinomas (22%) expressed neither gene. ConclusionsThe MAGE-A1 and -A3 genes can be expressed in cancer cell lines of salivary glands and relevant clinical carcinomas in addition to other malignant tumors of various histological origins. The results suggest the possibility of immunotherapy against salivary gland carcinomas by using MAGE-gene-encoded products as target antigens for tumor-rejection.

    Background: In Sweden, there are over 3000 new lung cancer cases every year. There are still numerous patients with undetermined lesions after routine diagnostic evaluation by clinical examination, chest radiography, computed tomography (CT) of the thorax, and bronchoscopy. An appropriate method for further diagnostic workup is therefore needed. Purpose: To evaluate the diagnostic value of the somatostatin analogue depreotide in patients with suspected lung cancer, and to determine in which clinical settings it would be beneficial to use 99mTc-depreotide scintigraphy. Material and Methods: We included 99 consecutive patients referred to our hospital with suspected lung cancer. A clinical examination, bronchoscopy, chest radiography, CT of the thorax and upper abdomen, and scintigraphy were done. Scintigraphy was performed after injection of 740 MBq 99mTc depreotide with tomographical imaging of the thorax and whole-body scanning. The diagnostic outcome of the scintigrams was compared to CT, using morphology or clinical outcome as the endpoint. Results: 99mTc-depreotide uptake was found in 62 out of 66 malignancies, including 57 of 58 primary lung cancer cases. Two cases of lung metastasis (one from a colon cancer and one from an adenoid cystic carcinoma originating in the palate) and one rib chondrosarcoma did not show depreotide uptake. There were 33 patients with benign lesions, of whom 16 displayed false-positive 99mTc-depreotide uptake, whereof 11 were pneumonias. Tc-99m-depreotide uptake was absent in 17 patients with benign lesions, including all 10 hamartomas. The sensitivity in detecting malignancy was 94%, and in detecting lung cancer 98%. The specificity was calculated based on two sets of data. When all cases were used, the specificity was 52%. If the 12 pneumonias are excluded, the specificity was 77%. Conclusion: 99mTc-depreotide scintigraphy has a high sensitivity in detecting lung cancer. The method is useful in decision-making with respect to

    Full Text Available Adenoviruses are important human pathogens that have been developed as vectors for gene therapies and genetic vaccines. Previous studies indicated that human infections with adenoviruses are self-limiting in immunocompetent hosts with evidence of some persistence in adenoid tissue. We sought to better understand the natural history of adenovirus infections in various non-human primates and discovered that healthy populations of great apes (chimpanzees, bonobos, gorillas, and orangutans and macaques shed substantial quantities of infectious adenoviruses in stool. Shedding in stools from asymptomatic humans was found to be much less frequent, comparable to frequencies reported before. We purified and fully sequenced 30 novel adenoviruses from apes and 3 novel adenoviruses from macaques. Analyses of the new ape adenovirus sequences (as well as the 4 chimpanzee adenovirus sequences we have previously reported together with 22 complete adenovirus genomes available from GenBank revealed that (a the ape adenoviruses could clearly be classified into species corresponding to human adenovirus species B, C, and E, (b there was evidence for intraspecies recombination between adenoviruses, and (c the high degree of phylogenetic relatedness of adenoviruses across their various primate hosts provided evidence for cross species transmission events to have occurred in the natural history of B and E viruses. The high degree of asymptomatic shedding of live adenovirus in non-human primates and evidence for zoonotic transmissions warrants caution for primate handling and housing. Furthermore, the presence of persistent and/or latent adenovirus infections in the gut should be considered in the design and interpretation of human and non-human primate studies with adenovirus vectors.

    The purpose of this study was to evaluate the efficacy of transoral or transnasal endoscopic-guided adenoidectomy compared with endoscopic nasopharyngeal inspection at the end of curettage adenoidectomy. A prospective case series of patients who had adenoidectomy. A total of 27 girls and 34 boys (age range 2.5-18 years) in whom adenoidectomy with or without tonsillectomy procedure was planned were included in the study. The cases were divided into three groups. Group 1 Transoral endoscopic-guided adenoidectomy performed patients. Group 2 Transnasal endoscopic-guided adenoidectomy performed patients. Group 3 Transnasal endoscopic nasopharyngeal exploration performed at the end of the conventional curettage adenoidectomy. The study was completed on 61 children. Mean age and sex frequency were not significant different between the groups. Mean operative time were 11.6 ± 2.9, 15.6 ± 4.4 and 9.7 ± 2 min, respectively (p > 0.05). On the other hand, significant differences were observed in operative time between group 1 and group 2 (p < 0.05), and between group 2 and group 3 (p < 0.05). Transnasal endoscopic examination at the end of curettage adenoidectomy is an appropriate method to assess the residual adenoid tissue after conventional curettage adenoidectomy. Also, operative time of this method is shorter than transoral or transnasal endoscopic-guided adenoidectomy. We recommend transnasal endoscopic inspection in all patients after conventional curettage adenoidectomy.

    Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Discovered on GIST-1 (DOG1) is a recently described protein expressed in GISTs irrespective of mutation status. The aim of this study was to investigate the immunohistochemical expression of DOG1 using 2 different monoclonal antibodies (DOG1.1 and the commercially available K9 antibody) in 668 GIST cases and to compare the results with the expression of KIT. DOG1 and KIT expression also were studied in most human normal tissues and several nonmesenchymal and mesenchymal tumors other than GIST. KIT was expressed in 643 (96.3%) GISTs. DOG1.1 and K9 were positive in 538 (80.5%) and 642 (96.1%) GIST cases, respectively. In 25 (3.7%) KIT-negative GIST cases, DOG1 was expressed in 5 (20.0%) and 19 (76.0%) using DOG1.1 and K9 antibodies, respectively. Only 0.9% of GISTs were negative for KIT, DOG1.1, and K9. Most normal human tissues did not reveal KIT and DOG1 expression. DOG1.1 was positive in only 2 of 57 synovial sarcomas and 1 of 61 soft tissue leiomyosarcomas. K9 was positive in 5 of 57 synovial sarcomas, 1 of 14 angiosarcomas, 1 of 61 soft tissue leiomyosarcomas, 3 of 4 adenoid cystic carcinomas of the head and neck, and in myoepithelial cells of 9 of 11 fibroadenomas of the breast. In conclusion, the commercially available K9 is of great utility for the diagnosis of most KIT-negative GISTs, and the combination of both KIT and K9 antibody in a panel of immunohistochemistry can define the diagnosis of GIST in more than 99% of cases.

Objective: To relate the nasolaryngoscopic findings with prolonged pH probe esophageal monitoring in children with clinical manifestations of extra-esophageal reflux. Method: Transversal prospective clinical study, in which we evaluated 44 children from one to 12 years old, of both genders, by means of nasolaryngoscopy. All were submitted to pH probe monitoring for research of hidden reflux due to cases of otitis, sinusitis, asthma, laryngitis and/or dysphonia in the last 12 months. Results: Out of 44 children, 15 (34% presented with normal pH monitoring and 29 (66% with altered monitoring. Out of 29 with altered pH monitoring, 19 (65.5% were boys and 10 (34.5% were girls. There was no statistically significant difference between gender and the positive results of pH monitoring, in spite of a discreet predominance of occurrence in the male population. All children had smaller adenoids than 75% of the cavity of concha aerial column. Six presented with purulent secretion in nasal cavity. Eight (18% had nodes in vocal cords and five (11% of whom had an altered pH monitoring and three (7% of whom were normal. We found at least one alteration upon nasolaryngoscopy in 80% of the 15 children with normal pH monitoring and in 89.7% of the 29 who had an altered pH monitoring. Conclusion: The prevalence of gastroesophageal reflux in children with recurrent respiratory and otorhinolaryngological affections was high. However, the data obtained didn't show any statistically significant difference (p<0.05 among the nasolaryngoscopic findings, associated or not with gastroesophageal reflux, confirmed by pH monitoring. Therefore, no relationship was found between the pathological gastric acid reflux and nasolaryngoscopic alterations.

    Full Text Available Lakshman Gollapalli, Rudramanaidu Muppuri Department of Anesthesiology and Pain Medicine, Wayne State University/Detroit Medical Center, Detroit, MI, USA Abstract: In patients with advanced stages of cancer, severe pain is commonly encountered and is very difficult to treat. It affects the quality of life of the patient and the families involved. Pain can be managed using analgesics and adjuvant therapy. However, studies have shown that at least 10%–15% of patients fail to control pain adequately and will experience severe pain. We discuss the case of a 66-year-old female with metastatic adenoid cystic carcinoma of the left submandibular gland and developed paraplegia following intercostal neurolysis with phenol. After a successful diagnostic T6 to T12 intercostal nerve block, the patient was scheduled for an intercostal neurolytic block. We injected 2 mL of 10% aqueous phenol at each level on the left from the T6 to T12 ribs. One hour after the procedure, the patient developed bilateral lower extremity weakness with difficulty moving. A physical examination showed the absence of sensation to pinpricks and vibration from T10 to S5 and an absence of anal sphincter tone and sensation. Magnetic resonance images of the thoracic and lumbar spine showed leptomeningeal metastatic disease and myelitis. We postulate that the paraplegia could be from phenol diffusing along either the spinal nerves or the paravertebral venous plexus into the subarachnoid space. This case report points to the risks involved with phenol neurolysis close to the spine, and we propose alternative methods to minimize neurological complications.

    Salivary gland basaloid neoplasms are diagnostically challenging. Limited publications report that some basal cell adenomas harbor CTNNB1 mutations, and nuclear β-catenin expression is prevalent. We evaluated β-catenin expression in basal cell adenomas and adenocarcinomas in comparison with salivary tumors in the differential diagnosis and performed targeted genetic analysis on a subset of cases. β-catenin immunohistochemistry was performed on formalin-fixed, paraffin-embedded whole sections from 73 tumors. Nuclear staining was scored semiquantitatively by extent and intensity. DNA was extracted from 6 formalin-fixed, paraffin-embedded samples (5 basal cell adenomas, 1 basal cell adenocarcinoma) for next-generation sequencing. Nuclear β-catenin staining was present in 18/22 (82%) basal cell adenomas; most were diffuse and strong and predominant in the basal component. Two of 3 basal cell adenocarcinomas were positive (1 moderate focal; 1 moderate multifocal). All adenoid cystic carcinomas (0/20) and pleomorphic adenomas (0/20) were negative; 2/8 epithelial-myoepithelial carcinomas showed focal nuclear staining. Most β-catenin-negative tumors showed diffuse membranous staining in the absence of nuclear staining. Four of 5 basal cell adenomas had exon 3 CTNNB1 mutations, all c.104T>C (p.I35T). Basal cell adenocarcinoma showed a more complex genomic profile, with activating mutations in PIK3CA, biallelic inactivation of NFKBIA, focal CYLD deletion, and without CTNNB1 mutation despite focal β-catenin expression. Nuclear β-catenin expression has moderate sensitivity (82%) for basal cell adenoma but high specificity (96%) in comparison with its morphologic mimics. CTNNB1 mutation was confirmed in most basal cell adenomas tested, and findings in basal cell adenocarcinoma suggest possible tumorigenic mechanisms, including alterations in PI3K and NF-κB pathways and transcriptional regulation.

  12. Expandable metallic stents in the palliative treatment of malignant tracheobronchial stenosis

    International Nuclear Information System (INIS)

    The purpose of this study is to report the outcome of using expandable metallic stent in the management of malignant tracheobronchial stenosis with dyspnea. Under fluoroscopic and bronchoscopic guidance, seven patients with malignant airway stenosis were treated with ten expandable metallic stents. The cause of stenosis was metastasis from esophageal cancer in five patients, recurrent adenoid cystic carcinoma of the trachea in one, and primary lung cancer in one. The major sites of obstruction were the trachea in four patients, the left main bronchus in one, the trachea and left main bronchus in one, and the trachea and both bronchi in one. Chest radiography (n=7), bronchoscopy (n=5), pulmonary function test (PFT)(n=3), and spirometry(n=1) were performed before and after stent placement. In all seven patients, the stent was successfully placed at the lesion sites and dyspnea began to improve immediately. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After stent placement, forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) improved 53% and 56%, respectively. Peak flow velocity also changed from 46 L/min to 200 L/min. During median follow-up of 67 (41-1565) days, one stent migration occurred. In one patient, proximal tumor overgrowth occurred, and in one, tumor ingrowth was treated with balloon dilatation. For in the palliative treatment of malignant tracheobronchial stenosis with dyspnea, placement of expandable metal stents is safe and effective. (author). 21 refs., 1 tabs., 3 figs
