    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.)

    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

    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.

    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.

    2011-01-01

    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

  17. 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)

    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.

    2013-01-01

    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.

  7. 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.

    We present a case report of an auxiliary nurse who developed an adenoid cystic carcinoma in her left maxillary sinus following occupational exposure to formaldehyde in the operating theatre. Currently, the epidemiological evidence that formaldehyde can cause cancer in humans is considered to be limited. Previous case-control-studies of formaldehyde and sinonasal cancer have mainly investigated subjects who were concomitantly exposed to wood dust, a known risk factor to the development of sinonasal adenocarcinoma of intestinal type. Our case report presents a patient who has developed an adenoid cystic carcinoma following exposure to formaldehyde. We suggest that the occupational physician remains alert to formaldehyde as an occupational hazard among health care workers.

    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.

    Objective: To investigate the expression of epidermal growth factor receptor, a receptor tyrosine protein kinase, in the subcellular fractions of human salivary adenoid cystic carcinoma cell lines SACC-83 and SACC-LM. 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.

    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.

    Le carcinome neuro- endocrine cutané primitif (CNEC) est une tumeur cutanée rare et agressive du sujet âgé, favorisée par le soleil et l'immunodépression. Elle est caractérisée par une évolution agressive avec un fort taux de récidive, une évolution ganglionnaire régionale et un risque de métastases à distance. Nous rapportons un cas de cette tumeur chez un patient âgé de 67 ans sous forme d'un placard nodulaire hémorragique mesurant 16 /14 cm. Le patient a bénéficié d'une exérèse chirurgicale large avec couverture de la perte de substance par un lambeau musculo-cutané du muscle grand dorsal, un curage ganglionnaire axillaire et une radiothérapie adjuvante. Après un recul de 2 ans et 2 mois, le patient est toujours vivant sans métastase ni récidive. La littérature étant pauvre, la prise en charge diagnostique et thérapeutique est controversée et donc hétérogène. Globalement le pronostic est mauvais, et certains paramètres corrélés au pronostic sont précisés. PMID:26185585

[Conclusion] The shape and hypertrophy of ade noid are closely related with the incidence of SOM.

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

    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.

    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

  18. 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

  20. 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.

    2008-01-01

    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 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.

  16. 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.

    Directory of Open Access Journals (Sweden)

    Xi-Yuan Ge

    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.

    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.

    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.

  1. 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.

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.

    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.

    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

    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

    Objective Analises of tympanometry and otoacoustic emissions results in preschool children with adenoid hypertrophy. Methods Acoustic immittance and otoacoustic emissions results and parameters were collected in 75 preschool children (aged 3-7 years) with varying degrees of adenoidal hypertrophy. Results The rates of type A immitance curve and positive acoustic reflex and average peak ear canal pressure in children with degree III adenoid hypertrophy were all lower between those with degree I or II adenoid hypertrophy (p<0.05). The rate of positive DPOAEs in children with degree III adenoid hypertrophy were also lower than those with degree I (1–8 kHz) or II (1.5-8 kHz) hypertrophy (p<0.05). In chil-dren with type A tympanograms, the rate of positive DPOAEs (0.5 – 2 kHz) in those with no acoustic reflex was lower than those with positive acoustic reflex (p <0.05). Conclusion Preschool children with adenoidal hypertrophy should re-ceive routine acoustic impedance and/or otoacoustic emission tests for early diagnosis of secretory otitis media in this popu-lation. The level of hypertrophy adenoidal can affect middle ear functions in these children, with higher levels of adenoid hy-pertrophy more likely to cause secretory otitis media of greater severities.%目的:探讨与研究学龄前儿童腺样体肥大的声导抗和耳声发射。方法选取75例3~7岁不同程度腺样体肥大儿童,依次进行声导抗和耳声发射测试,并记录结果和参数。结果腺样体Ⅲ度肥大患儿出现A型鼓室图的概率、声反射引出率、平均峰压值均明显低于I度及II度肥大患儿,差异有统计学意义(P<0.05);腺样体III度肥大患儿的DPOAE较I度肥大患儿(1~8kHz),较II度肥大患儿(1.5~8kHz)引出率低,差异有统计学意义(P<0.05);声导抗为A型的患儿中,声反射未引出者的DPOAE在0.5~2kHz区域引出率低于声反射引出者,差异有统计学意义(P<0.05)。结论

    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

    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.

  7. 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

  14. 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

    We present the main MR features of cystic lesions around the knee joint. Popliteal cysts are the most frequently seen. The usually result from extrusion of joint fluid into the gastrocnemio-semimembranosus bursa but they can have an atypical location or extension. They are most often due to a meniscal, ligamentous, degenerative or inflammatory joint disease responsible for a chronic joint effusion. Meniscal cysts are always associated with a horizontal tear. Medial meniscal cysts are larger and can extend far from the joint. Bursitis occur as a result of inflammation or infection of a bursa. Their location is stereotyped and they do not communicate with the knee joint. Ganglion cysts or ganglia are benign cystic lesions which can affect peri-articular tissues as well as subchondral bone or cruciate ligaments. MRI is now a simple and noninvasive way of obtaining etiologic diagnosis and guiding therapy. (authors). 46 refs.

    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.

    Penile tumors are the rarest male urogenital tract tumors (1%). Squamous cell carcinoma is the most common histologic type (95%). Radical surgical excision, though often mutilating, remains the best treatment for localized stages, in terms of local control (6% local recurrence). There are other therapeutic weapons and their possible indications should be adapted to the locoregional extension and at a distance from the primary tumor. We report the case of Mr AS aged 61, without particular pathological antecedents, who consulted, 6 years before, for an ulcerated burgeoning in the anterior surface of the penile bleeding on contact, which extended along the penis, without involving the glans penis. Evolution was marked by tumor progression with extension to the anterior pelvic wall. The patient went into a critical state of hemorrhagic shock. After stabilizing the hemodynamic status, a biopsy of the penis lesion confirmed the diagnosis of well-differentiated squamous cell carcinoma. An evaluation of the extent of loco-regional recurrence and distant metastasis showed pulmonary micronodules in the right lung. The case was discussed at the Multidisciplinary Consultative Meeting and patient was deemed inoperable and offered palliative chemotherapy. The prognosis of advanced stages of penis cancer is reserved; their frequency in our context is related to the modesty of patients, which explains the causes of delay in medical examination. Only socio-cultural awareness allows early diagnosis and, therefore, a better prognosis. PMID:27231503

    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.

    ABSTRACT:Objective To investigate the curative effects of specific sublingual immunotherapy with Dermatophagoides farinae drops on allergic rhinitis complicated by adenoid hypertrophy in children.Methods Ninety children with allergic rhinitis and adenoid hypertrophy randomly re-ceived sublingual immunotherapy with Dermatophagoides farinae drops(group A,n=30),conven-tional treatment with anti-allergic drugs(group B,n=30),or their combination(group C,n=30). Nasal symptoms(nasal congestion,nasal itching,sneezing,runny nose,etc.)and snoring symp-toms(labored breathing,waking up repeatedly,snoring,mouth breathing,etc.)were evaluated u-sing the visual analogue scale(VAS)before and after treatment for 6 months.The maximum thickness of adenoid/anterior-posterior diameter of nasopharyngeal air space (A/N)ratio was measured by X-ray absorptiometry and computed tomography.Results Before treatment,there were no significant differences among the three groups in VAS scores of nasal symptoms and sno-ring symptoms,as well as in A/N ratio(P >0.05).After treatment for 6 months,VAS scores of nasal symptoms and snoring symptoms and A/N ratio obviously reduced in all the three groups (P 0.05).Compared with group B,VAS scores of snoring symp-toms and A/N ratio increased in group A but decreased in group C(P <0.05).Conclusion There is a close relationship between allergic rhinitis and adenoid hypertrophy in children.Specific sub-lingual immunotherapy not only improves nasal allergic symptoms,but also relieves snoring symptoms through reducing adenoid volume.Therefore,specific sublingual immunotherapy pro-vides a new method for non-surgical treatment of allergic rhinitis complicated by adenoid hyper-trophy.%目的:探讨儿童过敏性鼻炎伴腺样体肥大患儿采用舌下含服粉尘螨滴剂治疗的疗效。方法将90例过敏性鼻炎合并腺样体肥大的患儿按随机数字表法分为 A、B、C 3组,每组30例。A 组给予舌下含服粉尘螨滴剂治疗;B 组

    PURPOSE:To investigate the expression of ErbB3 binding protein ebpl, E-cadherin, ICAM-1 and matrix metalloproteinase-9 (MMP-9) in salivary adenoid cystic carcinoma (SACC), and to explore their relationship with clinical pathological features. METHODS:Two-step immunohistochemical staining method was used to detect the expression of ebpl E-cadherin, ICAM-1 and MMP-9 in 33 cases with human SACC and 33 with para-cancerous normal tissues. All data were analyzed with SPSS17.0 software package. RESULTS:Positive expression rate of ebpl in SACC was 84.85%, lower than in normal salivary tissues (96.97%). Ebpl expression was significantly correlated to pathological pattern and clinical stage (P<0.05),but not correlated to gender and age. Positive expression rate of ebpl at Ⅰ- Ⅱ stage was higher than that of SACC at Ⅲ - Ⅳ stage; in regard to pathological typing, higher expression was found in adenoid tubular type than in solid type; the positive expression rate in patients with tumor metastasis was lower than in patients without metastasis (P<0.05). Expression of ebpl had a positive relationship with E-cadherin (r=0.851 ,P<0.01), while a negative relationship was found with MMP-9 (r=-0.364,P<0.05). CONCLUSIONS:Expression of ebpl may be associated with progression of SACC. Ebpl has important role in the generation and evolution of adenoid cystic carcinoma, and can be used as a useful indicator for clinical assessment of tumor biological behavior and prognosis in patients with adenoid cystic carcinoma.

    We hereby report a case of diffuse pelvic peritoneal involvement by immunoglobulin G4-related disease (IgG4-RD). Numerous pelvic masses and nodules showing delayed enhancement on enhanced abdominal CT were found to congregate in the pelvic organs of a 57-year-old female presenting with intestinal subocclusion. The differentiation between peritoneal IgG4-RD and pelvic peritoneal carcinomatosis was only made by histopathology and immunohistochemistry performed after surgical resection. Autoimmune pancreatitis represents the historical prototype of IgG4-RD, but the spectrum of manifestations involving various organs has expanded during the last decade. In this report, we shortly review this clinical entity.

    Most of patients with hepatocellular carcinoma (HCC) cannot benefit from surgical therapies. Among non-surgical options, only radiofrequency can challenge surgery for small size tumours. Conformal radiotherapy is likely highly efficient on solitary tumours, but controlled studies are warranted to conclude. Other options are purely palliative. Trans-arterial hepatic chemo-embolization is the goal-standard for multifocal hepatocellular carcinoma and Sorafenib for hepatocellular carcinoma with portal vein invasion, leading to modest but significant benefit on survival rates. Yttrium-90 radio-embolization is under evaluation through controlled studies, and could be of major interest for multifocal hepatocellular carcinoma with or without portal venous invasion. (authors)

    As the study of radioactive nuclide, Holmium-166 in the treatment of liver cancer(hepatocellular carcinoma), this study was performed under the base of animal experimental. Using dog liver, percutaneous injection of Ho-166 MAA or chitosan with premade dose was done under the ultrasound guidance. Continuously the same procedure as previous one was performed in the skin hapatoma, which was developed by the injection of hepatocellular carcinoma cell in the nude mouse, In case of injected normal liver of dog, imaging study including ultrasound, CT and MRI was done in order to evaluate effect of Ho-166 and pathologic reaction. The result showed well defined nectosis of normal liver as well as skin hepatoma. The area of nectosis is dependent on the dose of injected Ho-166. Generally, pathologic reaction is tissue coagulation nectosis, Ho-166 particles, fibrosis and hemorrhage. In the clinical study, 50 patients with hapatoma was selected for this study under the agreement of patient. Under ultrasound guidance percutaneous injection of Ho-166 Maa or chitosan to tumor was performed and follow-up study was extended from 6 to 12 month. The result showed that 64% of patient were completely treated. Overall, the effect of treatment could be obtained in 41 patient (82%) among 50 hepatoma patient. Conclusively Ho-166 is thought to be a compromising agent in the treatment of hepatocellular carcinoma and one of therapeutic modality, if it is established internally and world-wide. In the future, the popular percutaneous ethanol injection method will be replaced to this method. 19 refs., 1 tabs., 14 figs. (author)

  14. Skeleton scintigraphy and radiologic data at 403 patients with prostata carcinom

    International Nuclear Information System (INIS)

    In a retrospective study 403 patients with prostatic carcinoma (PC) were examined to shed light on the relation between the rate of metastases and the stage of local tumor spread as well as the histomorphologic tumor type; to establish the rate of metastases detected by bone scanning versus radiology; and to compare the contributions of bone scanning versus radiology in monitoring the response of bone metastases to treatment. Results: (1) The rate of metastases was found to increase as a function of primary tumor size and increasing dedifferentiation; however, bone metastases were also seen in highly differentiated stage O and A PC. (2) Solitary metastases were confined to the pelvic bones and lumbar vertebrae. (3) About one third of all bone metastases were radiologically silent; in sporadic cases receiving contrasexual therapy they remained silent for more than 5 years. (4) Bone scnaning showed 73.3% of patients to respond to contrasexual therapy and 26.7% to be non- responders. (6) There were some differences or even discrepancies between bone scans and radiology in documenting the results of treatment. Conclusions: Repeated bone scans are required for monitoring the course of the disease even if the primary tumor is extremely small and histologically well differentiated. Bone scans are superior to radiology in detecting metastases. While repeat X-rays during the course of a disease furnish important information, they are unsuited for monitoring the response to treatment. (Author)

    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

    El carcinoma basocel•lular (CBC) és la neoplàsia més freqüent en l’ésser humà. La importància d’aquest tumor rau tant en la gran morbiditat que produeix com en l’enorme despesa sanitària que ocasiona als sistemes de salut de gairebé tot el món. Malgrat que el seu tractament és essencialment quirúrgic, existeixen casos on no està indicat aquest abordatge terapèutic i seria interessant el fet de conèixer les alteracions moleculars que comporten la formació de la neoplàsia per tal...

  20. Results of fast neutron therapy of adenoid cystic carcinoma of the salivary glands

    International Nuclear Information System (INIS)

    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 were the changes in the values of sodium, potassium, chlorides, calcium, phosphorus, iron, and copper in the blood plasma as well as in that of hemoglobin, hematocrit, and the total count of blood cells in turkey poults experimentally infected with Eimeria adenoeides. The birds were divided into three groups of 40 each. The first and second were infected with various numbers of sporulated oocysts, while the third group was kept as a control one. It was found that Na, chlorides, Ca, P, and Fe were lowered, and K and Cu were increased over the same period. The total blood cell count and the hematocrit rose on the 4th and 5th day following infection, while they dropped on the 6th to the eighth day. The same was true of hemoglobin values.

    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.

    The eardrum necrosis is a serious and dreadful complication but rarely described after irradiation of cavum cancers. We report in this work five cases of eardrum necrosis after radiotherapy of nasopharynx carcinomas. Patients and methods: between february 1993 and december 2004 239 patients suffering of anon metastatic nasopharynx cancer have been treated by classical irradiation associated or not to a chemotherapy. The radiotherapy was delivered at the dose of 70 to 75 Gy in the cavum and the ganglions initially reached according a classical modality of hyperfractionated one. We analysed retrospectively the delayed complications occurred six months or more after the radiotherapy beginning. Results: Five cases of eardrum necrosis were reported sixty five months after the end of radiotherapy. these patients suffered of hypoacusia and buzzing. The clinical examination allowed to bring out the eardrum perforation that did not exist before radiotherapy. The total dose of irradiation was 75 Gy for a patient and 71.5 Gy according a hyperfractionated modality for four patients. Three patients had an hearing prosthesis in order to improve their quality of life. Conclusion: the eardrum necrosis after radiotherapy for nasopharynx cancer is a rare and unusual complication, very few reported in the literature. The total dose of irradiation is considered as the principal factor of occurrence risk in such complication. (N.C.)

    Choanal stenosis is usually a congenital anomaly in children. Acquired choanal stenosis after radiotherapy for nasopharyngeal carcinoma is a very rare pathology; only two publications report seven cases in the literature. We describe the clinical history, preoperative evaluation, surgical treatment and outcome of a case of acquired choanal stenosis after radiotherapy. The patient, a 56-year-old woman, presented with a history of nasopharyngeal carcinoma (T2- NO-MO) one year before that had been successful treated with radiotherapy (68 Gy). At the end of radiotherapy, she complained of complete nasal obstruction, anosmia and hearing loss due to a bilateral serous otitis media. Bilateral complete choanal stenosis was confirmed by endoscopy and CT scan. Functional endoscopic surgery was performed, and nasal stents were left in place for 3 weeks. One year after, the patient have good airflow, and a patent nasopharynx without choanal stenosis. In conclusion, choanal stenosis is an unusual complication of radiotherapy that can be successfully treated with trans-nasal endoscopic resection. (authors)

    Merkel cell carcinoma (M.C.C.) are rare neuroendocrine malignant tumor of the skin, occurring in elderly patients. It affects primarily the sun-exposed areas of the skin, with approximately 50% of all tumors occurring in the face and neck and 40% in the extremities. Immunohistochemical markers (C.K.20+, C.K.7- and T.T.F.1-) are used to distinguish between M.C.C. and other tumors. M.C.C. have a tendency to rapid local progression, frequent spread to regional lymph nodes and distant metastases. Due to the rarity of the disease, the optimal treatment has not been fully defined. Localized stages (stages I and II) are treated by surgical excision of the primary tumor (with 2 to 3 cm margin) and lymphadenectomy in case of node-positive disease, followed by external beam radiotherapy (E.B.R.T.) to a total dose of 50 to 60 Gy in the tumor bed. Adjuvant E.B.R.T. has been shown to decrease markedly locoregional recurrences and to increase survival in recent studies. Treatment of lymph nodes area is more controversial. Chemotherapy is recommended only for metastatic disease. (authors)

    Maxillary sinus carcinomas are rare malignancies of the face, characterized by high local relapsing rate. Modalities of treatment are without consensus and respective roles of radiation therapy and surgery remain controversial. As those malignancies are often diagnosed at locally advanced stage, radiation therapy may frequently be used for patients having unresectable advanced disease. Nevertheless, surgery remains treatment of choice for more localized malignancies, in association with systematic postoperative radiotherapy. For those patients whose prognosis remains pejorative, it is necessary to precise the role of radiotherapy in first intention for inoperable tumors, to define necessity for nodal treatment performing and evaluate the place of neo-adjuvant or concomitant chemotherapy in a multimodal strategy.

    Radiotherapy is an essential treatment for many patients with head and neck squamous cell carcinoma. Its association with molecular targeted therapies represents a real progress. Among the recent advances in the molecular targeted therapy of cancer, the applications centred on E.G.F.R. are currently the most promising and the most advanced at clinical level. Considering the set of therapeutic tools targeting E.G.F.R., there are at present two well-identified emerging categories of drugs with monoclonal antibodies, on the one hand, and tyrosine kinase inhibitors, on the other. In many preclinical studies, the combination of anti-E.G.F.R. drugs with irradiation has led to additive or supra-additive cytotoxic effects. Furthermore, anti-angiogenic agents have shown promising results in association with anti-E.G.F.R. drugs and radiotherapy. This research effort has recently produced encouraging clinical results in advanced head and neck cancer with combination of cetuximab (an anti-E.G.F.R. monoclonal antibody) with irradiation with a significant impact on patient survival. Active and efficient clinical research is currently ongoing to determine the place of molecular targeted therapies in the treatment of head and neck cancer, particularly in association with radiotherapy.

    The increasing incidence of DCIS during the past 20 years needs a continuous evaluation of the treatment strategies and a multidisciplinary decision process. The management of the DCIS remains a challenging issue in 2003. Mastectomy should still be considered as the reference treatment which is able to guarantee cure in almost all cases, whereas breast conserving surgery followed by radiation therapy is associated with 7-10% of local recurrence. However, the increasing knowledge of the predictive factors of the local recurrence allows to propose a conservative treatment strategy to a large amount of patients, without negative impact on their prognosis. This review presents the arguments that permit to justify, the reasoned choice of the different therapeutic options according to the clinico-pathological situations. (author)

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    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.

    Neo-adjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery L. chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbi-mortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radio-chemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomized trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, oesophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center. (author)

    Purpose: To evaluate the treatment results of patients (pts) with Figo stage IB2, IIA, IIB cervical carcinoma (C.C.) treated with preoperative radio chemotherapy, followed by extended radical hysterectomy. Patients and methods: Retrospective study of 148 women treated to the Curie Institute for operable Figo Stage IB2 to IIB, biopsy proved C.C.. Among them, 70 pts, median age 46 years, were treated using the same regimen associating primary radio cis-platinum based chemotherapy,intracavitary LDR brachytherapy, followed by extended radical hysterectomy. Kaplan-Meier estimates were used to draw survival curves. Comparisons of survival distribution were assessed by the log-rank test. Results: Complete histological local-regional response was obtained in 56% of the pts (n = 39). Residual macroscopic or microscopic disease in the cervix was observed in 28 pts (40%). All but one had in situ microscopic residual C.C.. Lateral residual disease in the parametria was also present in nine pts, all with residual C.C.. Pelvic lymph nodes were free from microscopic disease in 56 pts (80%). Eight of 55 (11%) radiological N0 patients had microscopic nodal involvement, as compared to 6/15 (40%) radiological N1 (p = 0.03). Seventeen pts (25%) had residual cervix disease but negative nodes. After median follow-up of 40 months (range, 8-141), 38/70 patients (54.1%) are still alive and free of disease, six (8.6%) alive with disease, and 11 (15.8%) patients were lost for follow-up but free of disease. Conclusion: The treatment of locally advanced C.C. needs a new multidisciplinary diagnostic and treatment approach using new therapeutic arms to improve the survival and treatment tolerance among women presenting this disease.

    The authors report a work aimed at assessing the feasibility and toxicity of a re-irradiation treatment in stereotactic conditions using CyberKnife and cetuximab in the case of local relapses of epidermoid cancers of the ORL sphere. Thirty three patients have been submitted to this treatment between June 2007 and April 2009. Although six patients died by six months, this treatment seems to be a good alternative, and presents an acceptable short-term toxicity. Further studies are needed to compare this technique to other therapeutic techniques, and to assess the risk of long term complications. Short communication

    Occurrence of basal cell carcinoma (BCC) following radiotherapy for tinea capitis is well known. The aim of this study was to specify the clinical and histological features of these BCC seen in 33 patients (1995 000). Twenty seven men and six women were diagnosed with BCC. The age of onset varied between 32 an 62 years. Radiotherapy was received between 5 and 17 years of age. The interval between irradiation and the onset of carcinoma varied between 21 and 51 years. Total number of lesions was 55. Forty percent of BCC occurred on the occipital area, the number varied from 1 to 5 and the size from 2 to 45 mm. Clinically, the nodular type was found in 51% of cases. Pigment was present in 64% of cases. Histological study showed a nodular aspect in 76% and pigmentation in 63% of cases. Nodular and pigmented type were the predominant BCC occurring after radiotherapy for tinea capitis in our series. In the literature, BCC are the most frequent carcinomas occurring after radiotherapy (70-100%). Pigmentation was not described in other series. The nodular histological form was the most frequent.

    Objective To study the expression of p16, cyclin D1, Rb and phosphorylated Rb(Ser795) in the esophageal squamous cell carcinoma. Methods Immunohistochemistry was performed and analysed on 34 cases of paraffin-embedded tissues. Results The expression of phosphorylated Rb(Ser795) was positively correlated to that of cyclin D1 (r=0.401, P=0.021) and inversely to that of p16 (r=-0.348, P=0.044). In stepwise regression and the best subset regression, the expression of p16 (P=0.034) and phosphorylated Rb(Ser795) (P=0.030) were the only determinants of the mitotic index. Conclusion The expression of phosphorylated Rb(Ser795) could be considered as a mark of the interaction between p16 and cyclin D1. The detection of phosphorylated Rb, p16 and cyclin D1 will be possibly helpful to the oncogenesis investigation on the esophageal carcinoma.

    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.

    Case report: In order to stage hepatocellular carcinoma (H.C.C.), a patient was referred to PET/CT using fluorodeoxyglucose({sup 18}F) (F.D.G.) and, if necessary, fluoro choline({sup 18}F) (F.C.H.). H.C.C. was proven by biopsy of a hepatic mass discovered on CT performed for a biological recurrence of prostate cancer. Result: F.D.G. PET/CT did not show any anomaly. F.C.H. PET/CT was thus performed and showed various foci: the hepatic mass, a large abdominal adenopathy and an unexpected sub centimeter lung nodule. The diagnostic uncertainty mostly concerned this lung nodule which was biopsied and consisted of a metastasis of the prostate cancer. Due to the presence of two metastatic cancers, the patient's management was altered, with chemotherapy for the H.C.C. and hormone therapy for the prostate cancer. Conclusion: Several types of cancer take-up fluoro choline({sup 18}F), which is a powerful tool to detect metastases, in particular in case of rising levels of marker with a negative F.D.G. PET/CT. Even when F.D.G. PET/CT is positive, F.C.H. may reveal unexpected foci with other metabolic characteristics, although it is not specific of a given primary cancer, as well as F.D.G.. For staging of H.C.C., we thus recommend to perform PET/CT with both tracers. (authors)

    It is a prospective study in order to evaluate the feasibility and the toxicity of a chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil followed by a concomitant chemoradiotherapy in the treatment of non metastatic locally evolved undifferentiated carcinomas of the cavum. The conclusion was despite the low number of patients in our series, the observed results show that this neoadjuvant chemotherapy followed by a concomitant chemoradiotherapy in the locally evolved undifferentiated carcinomas of the cavum is feasible. however, the high acute toxicity needs the use of conformal irradiation techniques. Besides, a longer follow up is necessary to evaluate the therapy efficiency and the delayed toxicity of this protocol. (N.C.)

    The authors report a case of gastric, renal, pulmonary, and myocardial uptake of M.D.P.-Tc 99 m in a patient with parathyroid carcinoma. Parathyroid carcinoma is a rare cause of primary hyperparathyroidism which becomes complicated during its evolution by metastatic calcifications. Metastatic calcifications are frequently located in lungs and heart. If an adequate treatment is not undertaken, these calcifications progress and evolve into severe respiratory and cardiac complications. In our patient, quasi-complete disappearance of metastatic calcifications on the follow-up bone scintigraphy, performed four weeks after surgical cure of parathyroid tumour, indicates the great interest of this examination in early identification of metastatic calcifications and monitoring of their disappearance after treatment.

    Purpose. - To assess the potential benefit of a boost in patients treated with whole brain irradiation by a conventional linear accelerator for lung cancer solitary brain metastasis. Patients and methods. - From 2002 to 2006, a retrospective analysis was carried out from 64 unselected consecutive patients with secondary brain metastasis from lung cancer, treated with whole brain irradiation without surgical resection. Thirty patients (47%) received a boost in their brain metastases. Three potential prognostic factors were studied: sex, RPA score and improvement of neurological symptoms after radiotherapy. An analysis was conducted to determine whether an additional dose may improve survival in the absence of surgical resection. Results. - The mean follow-up was 4.9 months. The median overall survival was 8.5 months (6.4 to 10.7 months). The total dose of radiotherapy was the only significant prognostic factor for overall survival. The median overall survival was 6.2 months for patients without additional radiation versus 11.2 months for patients receiving a boost dose (p = 0.011). Sex, RPA score and improvement of neurological symptoms after radiotherapy were not found as prognostic factors for overall survival. Conclusions. - Boost delivered after whole brain radiation therapy by a conventional particle accelerator may provide a benefit in selected patients, especially for centres that do not have radiotherapy techniques in stereotactic conditions. This warrants further prospective assessment. (authors)

    In the department of nuclear medicine at Ibn Sina university hospital. Thyroid carcinoma follow-up strategy has been modified and includes cervical ultrasonography and thyroglobulin measurement. The role of radio-iodine scanning in the management of differentiated thyroid carcinoma is decreasing. Papillary and follicular carcinoma have good prognosis but late metastases exist and can lead to death. A lifelong follow-up is therefore mandatory. The main goal of follow-up is to detect earlier persistent or recurrent disease. (authors)

    Purpose. - While some patients presenting with hepatocellular carcinoma (HCC) benefit from curative therapies (transplantation, surgery, percutaneous ablation), others are only candidates for palliative options such as chemo-embolization or symptomatic care. Although conventional external-beam radiotherapy of the liver is regarded as little efficient and potentially toxic in cirrhotic patients, 3-dimensional conformal radiotherapy (CRT), by decreasing the amount of normal liver included in the radiation portal, allows dose escalation to occur without increasing the risk of radiation-induced hepatitis. This trial was designed to assess the efficacy and tolerance of CRT for small-size HCC in cirrhotic patients. Patients and methods. - Prospective phase II trial including stage A/B cirrhotic patients with small-size HCC not suitable for curative treatments; CRT consisted in a standard fractionation radiation, with a total dose of 66 Gy. Results. - Twenty-seven patients were included, 15 of whom had previously been treated for HCC; mean age was 68. Among the 23 assessable patients, 18 (78%) presented with complete response, 3 (13%) with partial response, and 2 with no response. Acute complications occurred in 24 patients, and were mainly acceptable (grade 1/2: 22 patients, grade 3/4: 11 patients, 4 (15%) of whom had clinical and/or hematological toxicities). Only 2 (9%) grade 3/4 clinical and/or hematological late toxicities are reported. Conclusion. - CRT is a non-invasive curative technique highly suitable for small-size HCC in cirrhotic patients; further investigations are needed to compare it to the other available treatments, and to integrate it into the curative therapeutic algorithm of HCC.

    Purpose. Using deformable registration methods from a phase two clinical study of air breath control during radiotherapy in patients suffering from severe respiratory insufficiency and non-small cell lung carcinoma. Patients and methods, Between April 2002 and November 2005, 22 patients with severe respiratory insufficiency were treated with curative intent by conformal therapy combined with active breathing control. Results. After a mean of follow-up of 22 months, the local control rate is 28% and the method is feasible despite the severe respiratory insufficiency. However the overall survival is still poor due to metastatic widespread. For the second part of the study, the clinical protocol was also used for two studies using deformable registration methods. In the first study, a deformable registration method has been developed in order to register several breath-hold 3D CT of the same patient acquired at several days of interval. It allowed quantifying the inter-fraction breath-hold reproducibility by analysing the resulting displacement field. For 6 patients, the breath-hold was effective, while for 2 patients, motion greater than 10 mm were detected. The second study aimed to simulate 4D images from 3D breath-hold images. Developing an ad-hoc methodology based on the interpolation of 3D dense deformation fields performed it. The approach has been validated with expert selected landmarks, with accuracy lower than 3 mm. Conclusion. ABC is feasible, even in case of severe insufficiency respiratory syndrome but metastatic widespread disease is still a major challenge even with an acceptable local control rate without serious side effects: regarding the deformable registration method. Such artificial 4D images could allow decreasing the dose need to acquire a full 4D image, to simulate irregular breathing pattern and to be used for 4D dosimetry planning. (author)

    Nasopharyngeal carcinoma (NPC) is a highly radiosensitive and chemo-sensitive. In the patient with locally advanced tumours, the results of conventional radiotherapy are unsatisfactory with significant rates of both local recurrences and distant metastases. The aim of this review is to report the innovative strategies for treatment of the nasopharyngeal carcinoma. Altered fractionation techniques can improve local control. The impact of the innovative techniques, including conformal radiation, stereotactic radiation and IMRT, on survival, must be evaluated in randomized trials. The encouraging early results obtained with concurrent (more than sequential) chemotherapy and radiotherapy must be confirmed in prospective randomized trial in endemic areas. (authors)

The aim of this study was to evaluate retrospectively the Antoine Lacassagne Cancer Center's experience in a treatment by concomitant bid radiotherapy and chemotherapy. Evaluation was based on analysis of the toxicity, the response rates, the survival, and the clinical prognostic factors. From 1992 to 2000, 92 consecutive patients were treated in our single institution. All of them had stage IV, unresectable squamous cell carcinoma of the pharynx and they received continuous bid radiotherapy (two daily fractions of 1.2 Gy, 5 days a week, with a 6-h minimal internal between fractions). Total radiotherapy dose was 80.4 Gy on the oropharynx and 75.6 Gy on the hypopharynx. Two or three chemotherapy courses of cisplatin (CP)-5-fluorouracil (5FU) were given during radiotherapy at 21 -day intervals (third not delivered after the end of the radiotherapy). CP dose was 100 mg/m{sup 2} (day 1) and 5-FU was given as 6-day continuous infusion (750 mg/m{sup 2}/day at 1. course; 430 mg/m{sup 2}/day at 2. and 3. courses). Special attention was paid to supportive care, particularly in terms of enteral nutrition and mucositis prevention by low-level laser energy. Acute toxicity was marked and included WHO grade III/IV mucositis (89%, 16% of them being grade IV), WHO grade III dermatitis (72%) and grade III/IV neutropenia (61%). This toxicity was significant but manageable with optimised supportive care, and never led to interruption of treatment for more than 1 week, although there were two toxic deaths. Complete global response rate at 6 months was 74%. Overall global survival at 1 and 3 years was 72% and 50% respectively, with a median follow-up of 17 months. Prognostic factors for overall were the Karnofsky index (71% survival at 3 years for patients with a Karnofsky index of 90-100% versus 30% for patients with a Karnofsky index of 80% versus 0% for patients with a Karnofsky index of 60-70%, p = 0.0001) and tumor location (55% at years for oropharynx versus 37% for pan-pharynx versus 28% for hypopharynx, p=0.009). These results confirm the efficacy of concomitant bid radiotherapy and chemotherapy in advanced unresectable tumor of the pharynx. The improvement in results will essentially depend on our capacity to restore in a good nutritional status the patients before beginning this heavy treatment. (author)

    As the human papillomavirus (HPV) is at the origin of 25% of upper aero-digestive tract cancers, and as these tumours present an increased radio-sensitivity compared to other tumours, probably due to a greater transcriptional activity of p53, the authors report the study on the influence of a decrease of the expression of the APP-BP1 in these tumours which could favour a radio-induced apoptosis. By using a reverse transcriptase polymerase chain reaction (RT-PCR), they assessed the APP-BP1 expression levels as well as expression levels of transcriptions coding onco-proteins known to be over-expressed in HPV+ tumours. They compared the radio-sensitivities of HPV+ and HPV- cells, the first one appearing to be greater than the second one. Short communication

    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.

    Metastatic lesions of the hand are uncommon. A report of a solitary metastasis to the hamate seems not to have appeared previously in the literature. A 46-year-old factory worker presented a rare tumor, clear-cell carcinom of the lung, metastasizing to an unusual location, the hamate. The symptoms simulated sympathetic dystrophy and diagnosis was delayed because of the late appearance of radiographic changes over 6 months after symptoms first appeared. Early bone scanning in patients with chronic pain may provide useful information prior to the appearance of X-ray changes.

    Summary L’ulcère de Marjolin désigne la transformation maligne d’une cicatrice de brûlure ou de toute autre plaie ou ulcération chronique. Le type histologique prédominant reste le carcinome épidermoïde, et il est caractérisé par son agressivité locale, des métastases plus fréquentes, un risque de récurrence et une mortalité plus importante que les carcinomes épidermoïdes classiques. Notre travail est une étude rétrospective portant sur 21 cas d’ulcère de Marjolin, colligés au service de chirurgie plastique du CHU Mohammed VI de Marrakech, avec pour but de relever les aspects épidémiologiques, thérapeutiques et évolutifs de cette pathologie. L’amélioration du pronostic nécessite non seulement un diagnostic et un traitement précoce, mais surtout une attitude préventive qui consiste en des greffes cutanées précoces et des soins réguliers de toute cicatrice de brûlure.

L’étude anatomopathologique et immunohistochimique est en faveur d'une tumeur neuroendocrine primitive du sein à grande cellules exprimant les récepteurs progestéroniques seulement. Vu le caractère inflammatoire de la tumeur une chimiothérapie est démarrée avec bonne évolution clinique. A la fin de la chimiothérapie on prévoit de réaliser une mastectomie avec curage axillaire et en fonction des résultats définitifs, une radiothérapie. Une hormonothérapie sera envisagée une 2ème étude immunohistochimique sur la pièce de mastectomie.

    2015-03-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Farhadi M

    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.

  1. 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.

    Cystic fibrosis (CF) has a high incidence in the French-Canadian population of Saguenay Lac-Saint-Jean (Quebec). The A455E mutation accounts for 8.3% of the CF chromosomes. This mutation was shown to be associated with a milder lung disease in the Dutch population. Twenty two CF patients distributed in 17 families and compound heterozygotes for the A455E mutation have been followed at the Clinique de Fibrose Kystique de Chicoutimi. Fourteen patients also carried the delta F508 mutation while the remaining eight patients had the 621 + 1G-->T mutation. Each patient was matched by sex and age to a patient homozygous for the delta F508 mutation. The pairs were analyzed for several clinical and laboratory variables. The A455E compound heterozygotes were diagnosed at a later age (P = 0.003) and had chloride concentrations at the sweat test lower than those homozygous for the delta F508 mutation (P = 0.007). More patients were pancreatic sufficient (P = 0.004). They had a higher Shwachman score (P = 0.001) and better pulmonary function tests (P < 0.02). CF patients compound heterozygous for the A455E mutation have a milder pancreatic and lung disease than the delta F508 homozygotes. Therefore, the A455E should be associated with a better prognosis.

    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.

  8. 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.

    2015-10-01

    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.

    Full Text Available Se realizó un estudio en 66 niños y 34 niñas de 2 a 12 años. Cincuenta fueron casos de otitis media con efusión (OME y 50 controles. El grupo etario más numeroso fue el de dos años. Los síntomas y signos más frecuentes fueron otalgia y fiebre (70% e hipoacusia (40%. Veintinueve casos (58% y sólo 12 controles (24% presentaron adenoides hipertróficas (p < 0.01 . La pérdida auditiva fue significativamente mayor en el grupo de casos y las curvas timpanométricas se relacionaron directamente con ella. No se demostró que la alergia fuera un elemento importante en la génesis de la OME, a diferencia de la hipertrofia de adenoides que constituyó nuestro hallazgo más importante.

    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.

  16. 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.

    Le cancer broncho-pulmonaire (CBP) de la femme enceinte est une entité rare, d’évolution péjorative. Cette situation devient de plus en plus fréquente, du fait de l'augmentation du tabagisme chez la femme. La transmission tumorale trans-placentaire avec atteinte fœtale est décrite surtout chez les femmes non traitées. Le traitement est multidisciplinaire et n'est pas bien codifié. Nous rapportons le cas d'une patiente de 23 ans chez qui le diagnostic d'un carcinome bronchique à petites cellules a été fait au cours de sa grossesse. Elle avait bénéficié d'une chimiothérapie pendant la grossesse, bien tolérée. L’évaluation radiologique a objectivé une stabilisation du processus pulmonaire.

The median age of the patients was 52 years old. Squam ous carcinom a was the most conmon type of malignancy (36 cases).Sixteen patients were inthe stage Ⅲ a and 20 patients in stage Ⅲb-Ⅳ Twenty patients had no prior chemotherapy and 20 received previous chemotherapy. Results Complete response was observed in 4 patients and partial response in 15 patients. The overall response rate was 47.5 %. The response rate of the primary chemothera-py was 60%. The secondary chemotherapy was 35%. The main toxity of NVB was neutropenia which was seen in all treated cases (80.5 % in Grade Ⅱ and Ⅲ) The local venous toxity was observed in 35 % of the patients. Conclusion The so-called standard chemotherapy with NVB plus PDD in the treatment of NSCLC may obtain a higher response rate and lower toxity. It is effective especially for the patients of in an earlier stage.

    Full Text Available Background: Saffron is harvested from the dried, dark red stigmas of Crocus sativus flowers. It is used as a spice for flavoring and coloring food as a perfume. It is often used for treating several diseases. We investigated the potential of the ethanolic extract of saffron to induce antiproliferative and cytotoxic effects in cultured carcinomic human alveolar basal epithelial cells in comparison with non-malignant (L929 cells. Materials and Methods: Both cells were cultured in Dulbecco′s modified Eagle′s medium and treated with the ethanolic extract of saffron at various concentrations for two consecutive days. Our study resulted in sequences of events marked by apoptosis, such as loss of cell viability, morphology changes that were evaluated by MTT assay and invert-microscope, respectively. Results: The results showed that the ethanolic extract of saffron decreased cell viability in malignant cells as a concentration and time-dependent manner. The IC 50 values against the lung cancer cell line were determined as 1500 and 565 μg/ml after 24 and 48 h, respectively. However, the extract at different concentrations could not significantly decrease the cell viability in L929 cells. Morphology of MCF7 cells treated with the ethanolic extract confirmed the MTT results. Conclusion: We also showed that even higher concentrations of saffron is safe for L929, but the extract exerts pro-apoptotic effects in a lung cancer-derived cell line and could be considered as a potential chemotherapeutic agent in lung cancer.

  1. Role of Natural Radiosensitizers and Cancer Cell Radioresistance: An Update

    Directory of Open Access Journals (Sweden)

    Arif Malik

    2016-01-01

    Full Text Available Cancer originates from genetic mutations accumulation. Cancer stem cells have been depicted as tumorigenic cells that can differentiate and self-renew. Cancer stem cells are thought to be resistant to conventional therapy like chemotherapy and radiation therapy. Radiation therapy and chemotherapy damage carcinomic DNA cells. Because of the ability of cancer stem cells to self-renew and reproduce malignant tumors, they are the subject of intensive research. In this review, CSCs radioresistant mechanisms which include DNA damage response and natural radiosensitizers have been summed up. Reactive oxygen species play an important role in different physiological processes. ROS scavenging is responsible for regulation of reactive oxygen species generation. A researcher has proved that microRNAs regulate tumor radiation resistance. Ionizing radiation does not kill the cancer cells; rather, IR just slows down the signs and symptoms. Ionizing radiation damages DNA directly/indirectly. IR is given mostly in combination with other chemo/radiotherapies. We briefly described here the behavior of cancer stem cells and radioresistance therapies in cancer treatment. To overcome radioresistance in treatment of cancer, strategies like fractionation modification, treatment in combination, inflammation modification, and overcoming hypoxic tumor have been practiced. Natural radiosensitizers, for example, curcumin, genistein, and quercetin, are more beneficial than synthetic compounds.

    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 Bowen′s disease is generally regarded as premalignant dermatoses. The disease affects both skin and the mucosa and has the potential to progress to invasive squamous cell carcinoma. There are descriptions of several histological variants of Bowen′s disease like psoriasiform, atrophic, pagetoid, etc. Acantholysis of anaplastic keratinocytes with bullae/cleft formation is described in premalignant condition like actinic keratosis and adenoid variant of squamous cell carcinoma, but there is lack of report describing this phenomena in Bowen′s disease. We present a case of unusual acantholytic variant of Bowen′s disease with focus of micro-invasive carcinoma.

    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

    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.

  5. 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.

    L’épithélioma basocellulaire est de loin la tumeur épithéliale maligne la plus répandue. L'atteinte faciale représente plus de 65% des cas et constitue un facteur de risque de récidive. L'objectif de notre travail est de rappeler les principes et modalités du traitement chirurgical. Sur une période de douze mois, nous avons pris en charge quarante-cinq patients atteints de carcinomes basocellulaires de la face. Le traitement chirurgical comprend deux volets: -carcinologique: emportant la tumeur et une marge de tissu sain; -et une chirurgie réparatrice faisant appel à la suture cutanée directe; greffes ou lambeaux loco -régionaux. L'examen histologique systématique des pièces opératoires permet la confirmation du diagnostic, le typage histologique et l'appréciation de la qualité de l'exérèse chirurgicale. Les résultats esthétiques sont jugés satisfaisants. Quant aux résultats carcinologiques, nous déplorons quatre récidives. Le traitement chirurgical des épithéliomas basocellulaires est le seul garant de la guérison. Au niveau de la face, il faut trouver le meilleur compromis entre impératifs carcinologiques et esthétiques. L'amélioration des résultats passe par: la prévention, le dépistage précoce des lésions, la collaboration étroite des anatomo-pathologistes et la création de comités de concertation pluri -disciplinaire pour la prise en charge des cas difficiles.

La perforation reste exceptionnelle âpres la pose d'un DIU cependant c'est une des complications les plus graves. Nous rapportant le cas d'une patiente de 49 ans, notion de pose de stérilet il y a 20 ans, suivie en oncologie pour un carcinome canalaire infiltrant du sein ayant bénéficiée d'un patey puis chimiothérapie adjuvante actuellement sous hormonothérapie, qui dans le cadre du bilan d'extension, un scanner thoraco-abdomino-pelvienne a objectivé la présence d'un DIU en sous hépatique. Sous guidage coelioscopique, on a réussie à retirer le DIU qui était enchâssé dans l’épiploon au niveau de la gouttière pariéto-colique droite. Nous insistons à travers cette observation et sous la lumière de la revue de la littérature sur l'efficacité et l'innocuité du DIU lorsque la technique et les indications sont rigoureusement respectées, mais aussi sur une des complications rarissime de la pose du DIU, et à mettre en évidence le rôle diagnostic et thérapeutique de la cœlioscopie dans la prise en charge de ces migrations.

    Le but de ce travail était d'analyser les caractéristiques cliniques, histologiques, thérapeutiques et pronostiques du cancer du sein chez l'homme. Il s'agissait d'une étude rétrospective portant sur six patients colligés au service de gynécologie obstétrique II, CHU Hassan II durant la période 2009-2012. L’âge moyen de nos patients est de 65.3 ans. Il s'agit dans 83.3% des cas, d'une tumeur rétroaréolaire dont la taille moyenne est de 44.16 mm. Nous avons retrouvé 4 (66.7%) T4, 1 (16.7%) T3 et dans un cas, une tumeur inclassable. Le type histologique le plus représenté est le carcinome canalaire infiltrant (66.7%). Le taux d'envahissement ganglionnaire axillaire est de 66.7%. L'hormonodépendance de ces tumeurs est prouvée dans 100% des cas. La survie à cinq ans est en cours d’évaluation. L'envahissement ganglionnaire, l'invasion du derme, le stade clinique TNM sont des facteurs qui influencent significativement la survenue de métastases. Aucun de ces facteurs de risque n'est apparu significatif en termes de survie globale. Le cancer du sein chez l'homme est une maladie rare (environ 1% des cancers du sein) au pronostic sombre. Le diagnostic est le plus souvent tardif et les lésions sont traitées à des stades avancés. PMID:24711870

    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.

    1982-08-01

    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.

  8. Replacement of Missing Anterior Teeth in a Patient with Chronic Mouth Breathing and Tongue Thrusting

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available Obstructive sleep apnea (OSA is a common condition in childhood and can result insevere complications if left untreated. It is showing a rising trend in India. A significantassociation with obesity has been observed; however, some children with enlargedtonsils and/or adenoids may even be underweight. The patient usually presents withsnoring and other respiratory problems like mouth breathing, choking and gaspingepisodes in night. Poor school performance and neurocognitive deficits have beenreported. Pulmonary hypertension and cor pulmonale are seen in severe cases. Besidesthe history and clinical examination, for definitive diagnosis an overnightpolysomnographic evaluation is the gold standard. In all cases, the specific treatmentranges from simple lifestyle modifications and medications to surgeries likeadenotonsillectomy.

    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.

  4. 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

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

  13. 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

  16. 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.

    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).

    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.

    Les tuméfactions cervicales représentent un motif fréquent de consultation, et les adénopathies en constituent l’étiologie la plus fréquente. L'examen clinique et les bilans paracliniques permettent, dans la majorité des cas de retrouver une étiologie. Néanmoins certaines de ces tuméfactions restent d'origine non précisée, portant donc l'indication d'une cervicotomie exploratrice. Il s'agit d'une étude rétrospective d'une série de 300 cas de tuméfactions cervicales isolées colligées au service d'ORL de l'hôpital militaire Avicenne de Marrakech entre 2001 et 2014. Tous nos patients ont bénéficié d'une cervicotomie exploratrice avec étude anatomo-pathologique. L’âge des patients varie entre 1 et 76 ans avec un âge moyen de 32,57 ans et une légère prédominance masculine de 52%. La symptomatologie qui a motivé une consultation chez 81% des patients était la tuméfaction latérocervicale. La localisation la plus fréquente était sous mandibulaire (33,34%). Les tuméfactions d'installation progressive ont été retrouvées chez 93,34% des patients. Les principales étiologies retrouvées dans notre étude après examen anatomopathologique étaient de deux types: soit d'origine ganglionnaire dominées par la tuberculose ganglionnaire cervicale (53,66%), le lymphome malin non hodgkinien (6,66%), les adénites réactionnelles non spécifiques (4,66%), la maladie deHodgkin (4,33%) et les métastases ganglionnaires cervicales (3,33%); soit d'origine non ganglionnaire dont le lipome cervicale (17,66%), les kystes branchiaux (6%), les kystes du tractus thyréoglosse (1,66%) et le lymphangiome kystique (1,66%). A la lumière des résultats obtenus et des données de la littérature, nous allons discuter l'intérêt et l'utilité de la cervicotomie exploratrice dans le diagnostic étiologique des tuméfactions cervicales lorsque les examens cliniques et paracliniques ne sont pas concluants, et ainsi d'analyser les aspects

    Bevezetés: A mikro-RNS-ek a gének szabályozásán keresztül szerepet játszanak a daganatok kialakulásában. Célkitűzés: A szerzők a „cancer field” elmélet tükrében nemcsak magát a tumoros folyamatot, hanem annak környezetét is vizsgálva igyekeztek feltérképezni a meso- és hypopharynxlaphám-carcinomák mikro-RNS-mintázatát. Módszer: A szerzők által kidolgozott térképbiopsziás (1.: tumor, 2.: tumortól 1 cm-re, 3.: 2 cm-re és 4.: 3 cm-re) mintavételt követően 13 friss fagyasztott szövetből real-time quantitative polimeráz láncreakciós módszerrel határozták meg a mikro-RNS-expressziót. Eredmények: A miR-221 csak mesopharynxszövetekben, míg a miR-21, miR-143 és miR-155 hypopharynxdaganatokban mutatott szignifikánsan magasabb expressziót. A tumoros és a hozzá közeli mikroszkóposan ép szövet mikro-RNS-mintázata hasonló volt, míg a távoli ép szöveteké eltért a tumortól. Következtetések: A szerzők a mikro-RNS-expressziós mintázat alapján sikeresen különítették el a hypopharynx- és mesopharynxdaganatokat, valamint a tumor környéki szöveteket. A módszer jövőbeni jelentőségét az adja, hogy betekintést enged a szövetek epigenetikus szabályozásába, így a tumoros folyamat olyan korán fellelhető, amikor a sejt még fenotípusosan ép. Orv.

    Introduction L'infection par le virus de l'hépatite B (VHB) est une affection grave suite à ses complications notamment la cirrhose et le carcinome hépatocellulaire (CHC). Les génotypes du VHB influent beaucoup sur son évolution et sur l'efficacité du traitement. Le but était d’évaluer les génotypes du VHB et les profils évolutifs des patients porteurs chroniques de l'AgHBs. Méthodes Étude transversale, menée au Centre hospitalo-universitaire de Kamenge et au Centre des maladies du tube digestif et du foie « CEMADIF » entre Juin 2013 et Mai 2014. Le génotypage, les dosages quantitatifs de l'AgHBe et de l'ADN virale B ont été réalisés au Laboratoire Cerba, Cergy Pontoise, France. L’évaluation de la fibrose était faite par le Fibrotest ou le FibroScan. Résultats Au total, 143 patients, 52,4% de sexe masculin, âge moyen 38,1 ans ont été inclus. Selon les marqueurs évolutifs, 112 patients (78,3%) avaient un AgHBe négatif. Quant à la charge virale, 106 patients (74,2%) avaient une virémie inférieure à 2000UI/ml et une fibrose minime inférieure à 7kpa selon le FibroScan. Parmi eux, 13 malades avaient un ADN du VHB indétectable (0,8UI/ml). Il a été possible de déterminer le génotype chez 51 patients qui avaient une virémie assez élevée pour permettre techniquement ce dosage. Ces patients avaient tous un génotype A. Conclusion Le génotype A du VHB est le plus fréquent à Bujumbura. Il est associé à un portage inactif élevé. PMID:27222687

    Full Text Available La prevención del cáncer de cuello uterino ha evolucionado rápidamente a consecuencia de la identificación de su causa, el Virus del Papiloma Humano (VPH. La asociación VPH/Cáncer de Cuello Uterino, es aplicable tanto al carcinoma escamocelular como al adenocarcinoma. Dos de los tipos oncogénicos, los VPHs 16 y 18, son responsables del 70% de los casos de cáncer de cuello uterino a nivel mundial. El VPH es muy prevalente entre personas sexualmente activas, y se puede identificar fácilmente mediante el uso de tecnologías capaces de detectar ADN y otros biomarcadores del VPH. El ADN y los biomarcadores se pueden detectar en todas las fases de la historia natural de la infección y del proceso neoplásico. Dicha trazabilidad unida a la validación clínica de las tecnologías de identificación, han permitido mejorar los protocolos de cribado del cáncer cervical. La proteína principal del virión, ya expresada, produce inmunógenos capaces de inducir fuertes respuestas inmunitarias cuando se administran vía intramuscular, y ésta es la base de la Vacuna frente a VPH.The UCC (Uterine Cervical Cancer prevention has suffered a great evolution because of the knowing of its cause, wich is the HPV (Human Papillomavirus.

    Cell sub-populations surviving to high radiation doses were selected. The KBm survival part was obtained by exposure to a mutagenic agent and irradiation, FaDum results of a progressive irradiation of FaDu. A semi-quantitative RT-PCR analysis revealed a significant overexpression of GST-μ and p53 genes for KBm and FaDum cell lines that remained stable for 18 months. The SF2, α, β, and MID parameters, determined by clonogenic assays, show no modifications of radiosensitivity. The variations of expression observed are not correlated to a radiosensitivity variation. The overexpression of GST-μ and p53 does not seem to be a radiosensitivity marker. Nous avons isolé des sous-populations de 2 lignées cellulaires humaines (KB et FaDu) de carcinomes des voies aéro-digestives supérieures survivant à de fortes doses d'irradiation. La fraction survivante KBm a été obtenu après exposition à un agent mutagène et à une irradiation, FaDum résulte de l'irradiation progressive de FaDu. Une analyse par RT-PCR semi-quantitative nous a permis de mettre en évidence une surexpression significative des gènes GST-μ et p53 pour les souches KBm et FaDum analysées après 18 mois de culture. Les paramètres, α, β, SF2, MID, déterminés par essais clonogéniques, n'indiquent pas de modification de la radiosensibilité. Les variations d'expression observées ne sont donc pas corrélées à une variation de radiosensibilité. La surexpression des gènes GST-μ et p53 ne semble pas constituer un marqueur de radiosensibilité.

    Introduction Décrire les aspects épidémiologiques, cliniques, endoscopiques et histologiques du cancer de l’œsophage (CO) au Togo. Méthodes Il s'agit d'une étude rétrospective descriptive et analytique menée sur 8 ans (Janvier 2005-Décembre 2012) dans le service d'hépato-gastroentérologie (HGE) du CHU Campus de Lomé. Etaient inclus les dossiers des patients hospitalisés pour CO confirmé histologiquement. Résultats Sur 8 ans, 24 patients remplissant nos critères d'inclusion ont été retenus soit 3cas de CO par an et 0,55% des hospitalisations. L’âge moyen des patients était de 57,08 ans (extrêmes: 32 et 82 ans). La dysphagie et l’épigastralgie étaient les motifs d'hospitalisation les plus rencontrés. L'alcool (n=15), le tabac (n=13) étaient les facteurs de risque les plus présents. A la fibroscopie, les lésions étaient ulcéro-bourgeonnantes et hémorragiques (n=12), ulcéro-bourgeonnantes (n=5); ces lésions siégeaient au niveau du 1/3 inférieur (n= 11), à l'union 1/3 supérieur 1/3moyen de l’œsophage (n= 13) et aucun au niveau du 1/3 supérieur. Seize lésions étaient des carcinomes épidermoïdes et 3 des adénocarcinomes. L’évolution dans le service a été fatale dans 2cas; 16 patients avaient été transférés en chirurgie pour des soins palliatifs et 5 patients (20,8%) étaient perdus de vue. Conclusion Le CO semble en augmentation au Togo. L'alcool et le tabac sont les facteurs de risque et le pronostic sévère dans notre série est lié au retard diagnostic. Son dépistage précoce passe par une consultation rapide devant toute dysphagie chez un sujet de 50 ans et plus. PMID:25883742

    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.

  14. 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.

  14. 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

    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.

  19. 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

  2. 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.)

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

    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.
