    Full Text Available Allergic fungal sinusitis (AFS is a disease of young immune competent adults. Nasal obstruction, nasal discharge, nasal allergy and proptosis were the most common presentations. Initial diagnosis of allergic fungal sinusitis requires high index of suspicion in patients presenting with chronic rhino sinusitis, such cases should be properly evaluated. Differentiation from invasive forms of fungal sinus disease is crucial

  2. Clinical consideration of fungal paranasal sinusitis

    International Nuclear Information System (INIS)

    Fungal paranasal sinusitis is included in the differential diagnosis of unilateral paranasal lesion. Recently the incidence of fungal paranasal sinusitis has been increasing. We reviewed 24 patients (9 males and 15 females) with fungal paranasal sinusitis treated at Muroran City Hospital between January 2001 and May 2006, and clinical presentation and CT findings with those of 56 patients (36 males and 20 females) with chronic unilateral sinusitis. Fungal sinusitis patients ranged in age from 45 to 87, and the average age was 65.9 years old. In contrast, the age of chronic sinusitis patients ranged from 24 to 83, and the average age was 54.4 years old. The chief complaint of both fungal sinusitis and chronic sinusitis included rhinorrhea, nasal obstruction and post nasal discharge. CT exam was performed in all patients. In 23 cases of paranasal fungal sinusitis and 54 cases of chronic sinusitis the findings involved the maxillary sinus. The most common observation (69.6%) was bone density within the affected sinus in fungal sinusitis. However, only 2 cases of chronic sinusitis (3.9%) showed calcification. All cases of fungal sinusitis were diagnosed by pathological examinations. Most cases were proved to be aspergillus, while only one case was mucor. We treated all cases surgically, 18 cases underwent Caldwell-Luc's procedure and 5 cases underwent endoscopic sinus surgery under local anesthesia. (author)

    Allergic fungal sinusitis (AFS) is a condition that has an allergic basis caused by exposure to fungi in the sinonasal tract leading to chronic inflammation. Despite standard treatment modalities, which typically include surgery and medical management of allergies, patients still have a high rate of recurrence. Subcutaneous immunotherapy (SCIT) has been used as adjuvant treatment for AFS. Evidence exists to support the use of sublingual immunotherapy (SLIT) as a safe and efficacious method of treating allergies, but no studies have assessed the utility of SLIT in the management of allergic fungal sinusitis. A record review of cases of AFS that are currently or previously treated with sublingual immunotherapy from 2007 to 2011 was performed. Parameters of interest included serum IgE levels, changes in symptoms, Lund-McKay scores, decreased sensitization to fungal allergens associated with AFS, and serum IgE levels. Ten patients with diagnosed AFS were treated with SLIT. No adverse effects related to the use of SLIT therapy were identified. Decreases in subjective complaints, exam findings, Lund-McKay scores, and serum IgE levels were observed. Thus, sublingual immunotherapy appears to be a safe adjunct to the management of AFS that may improve patient outcomes. PMID:25902841

    A young female complained repeated nasal discharge for over three months with discomfort of right cheek, and oral antibiotics had less effect. She has a history of "root canal therapy" five years before. Physical examination found purulent secretion in the right middle nasal meatus, and light tenderness in the right side of the maxillary sinus area. The CT scan of paranasal sinus shown possible fungal infection of right maxillary sinus. Finally the nasal endoscopic surgery confirmed the fungus ball of right maxillary sinus with foreign body (the root canal filling material). PMID:26685411

    Full Text Available Fungal involvement of the paranasal sinuses is frequently observed in the immunocompromised host and it can become lifethreatening if it is not diagnosed. Definitive diagnosis is made by tissue biopsy and culture. In this study biopsy materials of maxillary, ethmoidal and frontal sinuses of 60 patients with clinical manifestation of sinusitis and no response to medical therapy were assessed by mycological and pathological methods for the presence of fungi. Invasive fungal sinusitis was diagnosed in 3 patients and etiologic agents were Candida albicans, Rhizopus sp. and Aspergillus fumigatus. Predisposing factors in these patients were leukemia, diabetes mellitus and previous sinus and polyp surgery, respectively. Allergic fungal sinusitis also was seen in one patient and Alternaria sp. isolated from the biopsy material. Only the patient with allergic form of disease survived but all the patients with invasive form of fungal infection were expired. This clearly underscores the need of early recognition of fungal sinusitis in at risk population in order to start urgent treatment. In this study Nocardia asteroids also was isolated from the biopsy sample in a patient with sinunasal adenocarcinoma.

    Full Text Available Nasal septal perforation presents a distinct challenge to otorhinolaryngologists, and is aproblem for patients. Although it has a variety of causes, previous septal surgery is the mostcommon reason. We present a 57-year-old woman who had recurrent chronic sinusitis. Aleft nasal mass was noted and excised via endoscopic sinus surgery. Invasive aspergillosissinusitis was proven both grossly and histopathologically, and a nasal septal perforation wasalso noted during the operation. Although there has been only a single other case presentedby Siberry in 1997, we postulate that perforation of the nasal septum as with the casedescribed herein is a rare complication of invasive fungal sinusitis.

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation. PMID:26758863

  9. CT findings of fungal infection of maxillary sinuses

    International Nuclear Information System (INIS)

    In recent years, fungal infection of the paranasal sinuses has increased. However, the preoperative diagnosis is often difficult. We report four cases of fungal infection of the paranasal sinuses. Their CT scans. Showed: 1) A high density area in the homogeneous shadow. 2) A mass suspected of being a fungus ball surrounding the opening of the maxillary sinus to the nasal cavity. 3) Thickening of bone in the maxillary sinus except in the inner wall. These results indicate that CT scanning is useful in the diagnosis of fungal infection of the paranasal sinuses. (author)

  11. Allergic fungal sinusitis: clinico-pathological aspects. Findings on CT and MR

    International Nuclear Information System (INIS)

    Allergic fungal sinusitis (AFS) represents the most recently described form of chronic sinusitis caused by fungi. It occurs in affects teenagers and young adults with atopic antecedents. This disease is a non-invasive chronic sinusitis, fungus acts as the allergen, causing a host immune response, mediated by type I and III reactions. Typically, several paranasal sinuses are usually involved with unilateral predominance. Most common clinical findings are headache, different grades of nasal obstruction and proptosis. Diagnostic criteria have been proposed for this entity, including imaging findings obtained with computed tomography (CT). Computed tomography and magnetic resonance imaging findings together have recently been postulated as practically pathognomonic. Treatment and prognosis of this entity, different from other types of fungal sinusitis, makes important to achieve a correct diagnosis. On this task, imaging studies as CT and MR play an important role. (Author) 23 refs

    Mucociliary clearance is an important defence mechanism of upper and lower respiratory tracts. Any disturbance in the mechanism leads to stagnation of secretions and secondary infection with prolonged mucociliary clearance time. The present study was undertaken to establish normal mucociliary clearance time in our region and to evaluate its diagnostic and prognostic potential in chronic sinusitis of variable duration with and without obstructive diseases.

    Objective. The aim of our study was to try to determine the possible environmental risk factors for noninvasive fungal sinusitis in Egyptian patients. Methods. This is a prospective epidemiological case control study on the environmental risk factors of noninvasive fungal sinusitis. It included 60 patients and 100 age and sex matched controls. Results. There was a statistically significant relation between apartment floor, surface area, exposure to dust, exposure to cockroaches, poor air conditioning, and fungal sinusitis. Yet, no statistical significance was found between allergy related occupations, exposure to animals or plants, although their percentages were higher among cases, smoking, and urban or rural residence. Conclusion. We suggest that for patients with noninvasive fungal sinusitis a change in their living environment must be implied with better exposure to sunlight, larger well ventilated homes, proper cleaning of dust and cockroach extermination, and if possible the judicious use of air conditioners.

    2010-09-01

    Full Text Available Allergic fungal sinusitis (AFS has been recognized as an important cause of chronic sinusitis commonly caused by Aspergillus spp. and various dematiaceous fungi like Bipolaris, Alternaria, Curvalaria, and etc. Ulocladium botrytis is a non pathogenic environmental dematiaceous fungi, which has been recently described as a human pathogen. Ulocladium has never been associated with allergic fungal sinusitis but it was identified as an etiological agent of AFS in a 35 year old immunocompetent female patient presenting with chronic nasal obstruction of several months duration to our hospital. The patient underwent FESS and the excised polyps revealed Ulocladium as the causative fungal agent.

    Objective. We aim to describe the first case in the literature of allergic fungal sinusitis (AFS) presenting with hyperprolactinemia due to compression of the pituitary gland. Case Presentation. A 37-year-old female presented with bilateral galactorrhea and occipital headaches of several weeks. Workup revealed elevated prolactin of 94.4, negative pregnancy test, and normal thyroid function. MRI and CT demonstrated a 5.0 × 2.7 × 2.5 cm heterogeneous expansile mass in the right sphenoid sinus with no pituitary adenoma as originally suspected. Patient was placed on cabergoline for symptomatic control until definitive treatment. Results. The patient underwent right endoscopic sphenoidotomy, which revealed nasal polyps and fungal debris in the sphenoid sinus, consistent with AFS. There was bony erosion of the sella and clivus. Pathology and microbiology were consistent with allergic fungal sinusitis caused by Curvularia species. Prolactin levels normalized four weeks after surgery with resolution of symptoms. Conclusion. Functional endoscopic sinus surgery alone was able to reverse the patient's pituitary dysfunction. To our knowledge, this is the first case of AFS presenting as hyperprolactinemia due to pituitary compression. PMID:26998375

    Allergic Fungal Sinusitis (AFS) is a newly recognized form of benign, non invasive sinusitis the histopathologic features of which are similar to those of allergic bronchopulmonary aspergillosis. AFS is a rare condition. However, because treatment and prognosis vary widely, it is important that this disorder be recognized and differentiated from chronic bacterial sinusitis and other forms of fungal sinusitis. AFS does not discriminate by age although it is primarily found in young adults. AFS patients are usually atopic, often having a history of asthma and nasal polyposis. Many have suffered from the symptoms of chronic sinusitis for years while others have had multiple sinus surgery. Radiographs reveal the involvement of multiple sinuses, often with bone destruction. Laboratory findings support an allergic state with a marked increase in eosinophilia and total IgE. At times RAST testing proves positive for fungi and immediate cutaneous reactivity to fungi is also present. Histologic review of the sinus contents reveals characteristic "allergic mucin", with numerous eosinophiles, Charcot-Leyden crystals and fungal hyphae, without any fungi tissue invasion. A wide variety of fungal agents has been implicated, although the majority belong the Dematiacee family. Those patients with allergic mucin but no documented fungi are indicated as having AFS-like syndrome. The pathogenesis of AFS is uncertain. There is controversy in the literature as to what role hypersensitivity (Gell and Coombs type I and type III responses) in infection play. To date current therapeutic recommendations include complete exenteration of all allergic mucin. Adjunctive, short-term systemic steroids often prove useful and nasal steroid spray should be continued for long term. Systemic antifungal agents are not recommended in AFS. Recurrence is common and thus close clinical, endoscopic and radiographic follow-up is important. The clinicopathologic features of one patient with AFS are reported

  20. Differential diagnosis of fungal and nonfungal infection of the paranasal sinuses using CT: value of intralesional expansile ball-like high density

    International Nuclear Information System (INIS)

    To determine the usefulness of CT findings of an expansile ball-like high density mass in the differential diagnosis of fungal and nonfungal sinusitis. Paranasal sinus CT findings in 62 patients (36 males and 26 females) with pathologically proven chronic paranasal sinusitis were retrospectively analyzed. Sinusitis was fungal in 21 patients (34%) and nonfungal in 41 (66%). Bone and soft tissue window settings were reviewed by two radiologists in terms of the presence, expansibility, bilaterality, and location of the ball-like high density mass, involved sinuses, bone thickening of the sinus wall, and associated calcification. The ball-like high density mass was more common in fungal sinusitis patients (81%), in whom it was expansile in 88% of cases and unilateral in 94% (p<0.05). In all patients, the mass was located in the maxillary sinus; in 88% of fungal cases and 90% of nonfungal, it was present in both its medial and lateral portions. Bone thickening (76%) and calcification (86%) were more common in fungal sinusitis (p<0.05). A ball-like high density expansile mass appears to be a valuable finding in the diagnosis of fungal sinusitis

    Full Text Available The aetiology of fungal sinusitis is diverse and changing. Aspergillus species has been the most common cause for fungal sinusitis, especially in dry and hot regions like India. Trichosporon species as a cause for fungal sinusitis has been very rarely reported the world over. Here, we report a rare case of allergic fungal sinusitis caused by Trichosporon inkin in a 28-year-old immunocompetent woman. Bilateral nasal obstruction, nasal discharge and loss of smell were her presenting complaints. Diagnostic nasal endoscopy showed bilateral multiple polyps. Functional endoscopic sinus surgery was performed and many polyps were removed. Based on mycological and histopathological studies, the pathogen was identified as T. inkin.

The diagnosis of sinusitis is often clinical, but confirmation is thought to require a CT scan due to the difficulty of interpreting a Water’s view sinus X-ray.Objectives: The purposes of the study were (1 to examine the frequency of an abnormal sinus X-ray in children with a chronic cough of more than 4 weeks duration; (2 to compare the interpretation of the sinus film between allergy/pulmonary clinicians and radiologists; and (3 to correlate symptoms with X-ray results.Methods: A chart review of 2- to 18-year-old patients with coughing exceeding 4 weeks was performed. Data was collected for patients who had received a Water’s view sinus film as part of their evaluation. Exam, X-ray results, and clinical outcomes were categorized and statistical analyses performed.Results: A total of 86 patients were included. Clinicians found that 65% of the children had positive Water’s view films, compared with the radiologist’s reading of 62% (non significant. Significant associations between post-tussive emesis (P = 0.01 and purulence (P = 0.03 were noted with a positive film. Positive sinus X-ray was highly associated with all findings except wheeze when present together (P < 0.001.Conclusions: Sinus abnormalities on X-ray are associated with prolonged cough in 65% of children. The Water’s view sinus film is a clinically useful screening tool for clinicians in the workup of chronic cough. Certain physical findings and clinical complaints, when present concurrently, correlate with the X-ray results.Keywords: Water’s view sinus X-ray, asthma, allergic rhinitis, radiologist, post-tussive emesis, wheezing

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

    The aim of this study was to evaluate whether multislice CT enables quality improvement and dose reduction in the imaging of the paranasal sinuses, especially when using secondary reconstructions. We compared the imaging quality of direct CT scans and secondary reconstructions of single-slice CT (SSCT) as a criterion standard with multislice CT (MSCT) of the paranasal sinuses in 80 patients suspected of having chronic sinusitis. Coronary secondary reconstructions were calculated from all transversal CT data sets. Coronary reconstructions of transversal MSCT showed a significantly better image quality compared with coronary reconstructions of SSCT. Because of the absence of dental metal artifacts, coronary reconstructions of MSCT were superior even to direct coronary images of SSCT. MSCT offered a superior examination quality compared to SSCT. A halving of radiation dosage can be reached by eliminating one examination plane. PMID:15546176

    Full Text Available Abstract Background Risk factors and outcomes in hematological patients who acquire invasive fungal sinusitis (IFS are infrequently reported in the modern medical era. Method A retrospective study of hospitalized patients with hematological disease was conducted at National Taiwan University Hospital between January 1995 and December 2009. Results Clinical characteristics and outcomes with their associated radiographic and microbiological findings were analyzed. Forty-six patients with IFS and 64 patients with chronic non-invasive sinusitis were enrolled as comparsion. IFS developed more commonly in patients with acute myeloid leukemia (AML and with prolonged neutropenia (absolute neutrophil count less than 500/mm3 for more than 10 days (p Aspergillus flavus was the most common pathogen isolated (44%. Serum Aspergillus galactomannan antigen was elevated in seven of eleven patients (64% with IFS caused by aspergillosis but negative for all three patients with mucormycosis. Bony erosion and extra-sinus infiltration was found in 15 of 46 (33% patients on imaging. Overall, 19 of 46 patients (41.3% died within 6 weeks. Patients with disease subtype of AML (p = 0.044; Odds Ratio [OR], 5.84; 95% confidence interval [95% CI], 1.02-30.56 and refractory leukemia status (p = 0.05; OR, 4.27; 95% CI, 1.003-18.15 had worse prognosis. Multivariate analysis identified surgical debridement as an independent good prognostic factor (p = 0.047 in patients with IFS. Conclusions Patients of AML with prolonged neutropenia (> 10 days had significantly higher risk of IFS. Early introduction of anti-fungal agent and aggressive surgical debridement potentially decrease morbidity and mortality in high risk patients with IFS.

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

    Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults from the western world. No curative treatments of CLL are presently known so the treatment strategy today is primarily to prolong patient survival,1 why we have initiated new activities towards discovery of novel compounds...... with potential tumor specificity. Our starting point is a diverse fungal collection of thousands of Penicillium and Aspergillus species. These fungi have proven to be a very rich source of various bioactive compounds and yet our dereplication investigations have demonstrated that there are still...... numerous unknown compounds to be identified within these species. Until now we have found that 11 out of 289 fungal extracts are active against CLL cells. Using our established chemotaxonomic discovery approach we have dereplicated and fractionated these extracts to track the activity into single fractions/compounds...

  15. A combined study of CT and MRI in chronic maxillary sinusitis

    International Nuclear Information System (INIS)

    With CT of the paranasal sinusitis mucosal swelling can not be distinguished from fluid accumulation within the sinuses in patients with chronic sinusitis. We studied 12 cases of chronic sinusitis (17 sides) by means of CT and MRI, with which we could distinguish mucosal swelling from fluid accumulation in the maxillary sinuses. It was found that in a majority of cases with total clouding of the maxillary sinus the degree of swelling of mucous membrane was relatively small. This indicates that the main cause of total clouding of the maxillary sinus found in CT is due to accumulation of fluid rather than from obliteration of the sinus due to swelling of mucous membrane within the maxillary sinus.

    Chronic rhinosinusitis (CRS) is a very common disorder that remains poorly understood from a pathogenic standpoint. Recent research on the pathogenesis of CRS has been focused on the potential role of biofilms in this chronic infection. The aim of this study was to assess the sinuses' microflora and biofilm formation on the sino-nasal mucosa in patients with CRS. Paranasal sinus mucosa specimens were harvested at the time of functional endoscopic sinus surgery (FESS). Classical microbiology techniques for the isolation and identification of sinus mucosa microbial flora were used. Scanning electron microscopy (SEM) was used to detect biofilm on the surface of mucosa. A microtiter plate assay for in vitro biofilm formation was employed, divided into three aliquots. One part was assessed for bacterial presence, utilizing an API manual system and the Vitek(®) 2 Compact system. The two remaining aliquots were tested by in vitro conventional microbiological assay with the use of the Infinite M200 (Tecan) microtiter plate reader, and also by scanning electron microscopy (SEM). A microbiological examination of mucosal specimens had taken during FESS operation revealed the presence of various types of bacteria in 29 out of 30 tested samples. Out of 62 different strains isolated from patients with CRS, 23 strains of coagulase-negative Staphylococcus epidermidis and 6 strains of Escherichia coli were the most frequently isolated microorganisms, accounting for 37.1 and 9.7 %, respectively. Among the 62 isolated strains, 58 were used to assess biofilm formation. From the total of 58 isolates, 8.6 % were strong biofilm producers, 20.7 % were moderate, and 70.7 % of isolates were considered to be non- or weak biofilm producers. SEM of the 30 nasal concha mucosal samples taken from patients with CRS revealed biofilm in 23 specimens. A marked destruction of the epithelium was observed, with variation in degrees of severity, from disarrayed cilia to complete absence of cilia

  19. Aspergillosis of the maxillary sinus. A clinical analysis of 24 cases. Comparision with 30 cases of non-fungal maxillary sinusitis

    International Nuclear Information System (INIS)

    The clinical and radiographic findings of 24 patients with aspergillosis of the maxillary sinus treated from 1989 through 2004 were compared with those of 30 patients with non-fungal maxillary sinusitis to clarify factors related to differential diagnosis. The subjects with aspergillosis were 9 men and 15 women aged 26 to 78 years (mean, 52 years). The patients with non-fungal sinusitis were 25 men and 5 women aged 23 to 73 years (mean, 46 years). The most common clinical finding at presentation was cheek pain, followed by nasal symptoms in the aspergillosis group. Nasal symptoms were more common in the non-fungal group than in the aspergillosis group. Thus, pain was more often associated with aspergillosis. Radiographically, diffuse radiopacity was observed in the maxillary sinus of all patients in both groups. In addition, dense antral radiopacities indicative of calcification were seen in a patient with aspergillosis. On X-ray-CT scans, bone thickening of antral walls (23 cases), sand-like high density areas (20 cases), extension of soft tissue masses to the nasal cavity (17 cases), foamy low density areas (13 cases), and bone destruction (6 cases) were seen in the aspergillosis group. These findings were rarely seen in the non-fungal group. All patients in both groups were treated by radical surgery of the maxillary sinus. The postoperative course was uncomplicated, and there was no recurrence as of 1 year postoperatively. In conclusion, the presence of pain, bone thickening of antral walls, sand-like high density areas, extension of soft tissue masses to the nasal cavity, foamy low density areas, and bone destruction on X-ray-CT scans were valuable for diagnosing aspergillosis of the maxillary sinus.

  20. Why Caldwell-Luc and nasoantral window procedures fail in patients with chronic sinusitis

    International Nuclear Information System (INIS)

    CT was performed on 80 patients with recurrent symptoms of chronic sinusitis after Caldwell-Luc and/or nasoantral window procedures. In each case there was anterior ethmoid sinus inflammatory disease with obstruction of the normal ipsilateral maxillary sinus drainage, the ostiomeatal unit. When the ipsilateral frontal sinus was also diseased, the anterior ethmoid sinus inflammatory process was found to block the frontal recess. These findings indicate that patients who have chronic sinusitis after Caldwell-Luc and/or nasoantral window procedures fail because of persistent disease. The disease is characteristically situated in the anterior ethmoid cells, with blockage of mucociliary clearance from the maxillary and frontal sinuses. Therefore, the cure is predicated on surgical procedures directed to restoring patency of the ostiomeatal unit and frontal recess

    Full Text Available Background Identifying predisposing factors for chronic sinusitis is very important. Objectives Anatomical variation of the lateral nasal wall has been investigated in several studies and it has been suggested as a predisposing factor for sinusitis. Patients and Methods In this case-control study, 74 patients who were diagnosed with chronic sinusitis (the case group based on clinical criteria and CT scan were entered into the study and 74 patients without chronic sinusitis were considered as the control group. CT scans of all patients were reviewed by a radiologist to interpret and evaluate anatomic variations of anterior osteomeatal complex including nasal deviation, concha bullosa, agger nasi, lateralized uncinate, Haller’s cells, paradoxical middle turbinate, and maxillary hypoplasia. Data were analyzed using the chi-squared test and Fisher’s exact test with SPSS software version 18. P < 0.05 was considered statistically significant. Results Results showed that the most common sinus involved was maxillary sinus. Among anatomic variations, septal deviation and concha bullosa were associated with chronic sinusitis (P < 0.01 and P < 0.032, respectively. Conclusions Among anatomic variations, septal deviation and concha bullosa are predisposing factors for chronic sinusitis and we recommend that patients with chronic sinusitis be treated by surgical procedures.

    The prevalence of Aspergillus sinusitis is often underestimated because the vast majority of cases are classified as "unspecified sinusitis". Two possible aetio-pathogenic mechanisms can be involved in the development of this fungal infection. Traditionally, the literature emphasised the "anglophone" hypothesis which is based on the inhalation of spores. More recently, the "french" model, based on oro-sinusal fistula and/or the perforation of the maxillary sinus by root canal-filling material, is believed to explain the majority of cases in our industrialised environments. Still, neither model explains the totality of cases and several remain beyond comprehension. The disease most commonly presents as a chronic bacterial sinusitis. The process can however become invasive, thus resembling malignancy, with eventually a fatal outcome. Doctors and dentists should know the possible danger, presented by zinc-oxide-eugenol-paste in the sinus. Radical surgery is the treatment of choice, since a prolonged conservative approach (antibiotics, corticosteroids) can only worsen the prognosis. This paper discusses different aspects of the disease, and presents 10 cases, observed at the University Hospitals of Paris (France) and Leuven (Belgium). PMID:2406288

  5. Automatic region detection of maxillary sinus from human face radiographs in the assessment of recovery in chronic sinusitis

    International Nuclear Information System (INIS)

    Automatic region detection of the maxillary sinus from human face X-ray pictures is studied and presented. Firstly a new algorithm for transformation from X-ray images to bi-level images is introduced, which is based on the local properties of the images. Secondly, a region detection algorithm is used to determine global shape parameters of the maxillary sinus such as area, perimeter length, and complexity. It is shown that the regions of the maxillary sinus detected by the new algorithm coincide well with clinical diagnosis. It is also shown that the cumulative distribution function calculated from the density histogram of detected regions is a useful parameter for assessing the stage of recovery in chronic sinusitis.

  6. Basilar Artery Territory Stroke Secondary to Invasive Fungal Sphenoid Sinusitis: A Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Katherine A. Fu

    2015-03-01

    Full Text Available Background: Mucormycosis is a fungal infection with the following 5 classic forms: cutaneous, pulmonary, gastrointestinal, disseminated, and rhinocerebral. The rhinocerebral form can be rapidly progressive and invasive with a high mortality rate. We present a case of a 38-year-old man with invasive mucormycosis that led to a basilar artery territory stroke. Rhinocerebral mucormycosis is an unusual cause of stroke. Case Report: A 38-year-old man with a past medical history of diabetes mellitus presented with altered mental status. A lumbar puncture revealed eosinophilic pleocytosis with a mildly elevated total protein and borderline low glucose level. CT revealed a left medullary and cerebellar infarct confirmed by MRI. MRI also displayed a diffuse marrow signal abnormality in the clivus with contiguous sinus disease. Endoscopic sinus surgery confirmed that the fungal sinusitis was mucormycosis of the Rhizopus genus, which had affected the left sphenoid sinus, invaded through the skull base, and involved the basilar artery. He was given liposomal amphotericin (500 mg i.v. with posaconazole (400 mg i.v. twice daily. Due to the severity of the invasion and poor prognosis, the patient was discharged with comfort care measures. Discussion: Clinicians should be aware of invasive sinusitis as a rare cause of stroke in diabetics. Once the subarachnoid space and basal arteries of the brain have been invaded, the prognosis is very poor. The key to improvement of outcomes is early recognition and treatment, and examination of the sinuses on neuroimaging in all cases of stroke is vital.

  7. Morpho-functional evaluation of osteomeatal complex in chronic sinusitis by coronal CT

    International Nuclear Information System (INIS)

    The objective was to determine whether or not there exists a clinical-radiological correlation in chronic sinusitis of anterior paranasal sinus and to quantitatively evaluate the importance of osteomeatal complex structures and anatomic variants in chronic sinusitis etiopathology. We analyzed 208 nasal fossae with high-resolution and low-irradiation coronal computed tomography. The following inclusion criteria we established: one case control and one control group. We considered any chronic thickness of sinusal mucosal as a radiological indicator of chronic sinusitis. We evaluated the mucosal thickness of internal, external, superior and inferior maxillary walls, the addition of four maxillary walls and the maximal mucosal thickness in frontal sinus and anterior ethmoidal cells. We also obtained 15 parameters of osteomeatal complex structures and anatomical variants in each nasal fossa, and we correlated them statistically with chronic sinusitis radiological indicators. Uncinate process length is the only anatomic element from which we have been able to obtain a statistically significant cut point between case and control groups, but only with a sensitivity of 51.6%, specificity of 71.2%, positive predictive value of 74.2%, and negative predictive value of 47.9%. No association of radiological parameters exists that can explain chronic sinusitis. (orig.)

    Winfried Möller

    Full Text Available OBJECTIVES: Chronic rhinosinusitis (CRS is a common chronic disease of the upper airways and has considerable impact on quality of life. Topical delivery of drugs to the paranasal sinuses is challenging, therefore the rate of surgery is high. This study investigates the delivery efficiency of a pulsating aerosol in comparison to a nasal pump spray to the sinuses and the nose in healthy volunteers and in CRS patients before and after sinus surgery. METHODS: (99mTc-DTPA pulsating aerosols were applied in eleven CRSsNP patients without nasal polyps before and after sinus surgery. In addition, pulsating aerosols were studied in comparison to nasal pump sprays in eleven healthy volunteers. Total nasal and frontal, maxillary and sphenoidal sinus aerosol deposition and lung penetration were assessed by anterior and lateral planar gamma camera imaging. RESULTS: In healthy volunteers nasal pump sprays resulted in 100% nasal, non-significant sinus and lung deposition, while pulsating aerosols resulted 61.3+/-8.6% nasal deposition and 38.7% exit the other nostril. 9.7+/-2.0 % of the nasal dose penetrated into maxillary and sphenoidal sinuses. In CRS patients, total nasal deposition was 56.7+/-13.3% and 46.7+/-12.7% before and after sinus surgery, respectively (p<0.01. Accordingly, maxillary and sphenoidal sinus deposition was 4.8+/-2.2% and 8.2+/-3.8% of the nasal dose (p<0.01. Neither in healthy volunteers nor in CRS patients there was significant dose in the frontal sinuses. CONCLUSION: In contrast to nasal pump sprays, pulsating aerosols can deliver significant doses into posterior nasal spaces and paranasal sinuses, providing alternative therapy options before and after sinus surgery. Patients with chronic lung diseases based on clearance dysfunction may also benefit from pulsating aerosols, since these diseases also manifest in the upper airways.

    Individuals who survive near drowning often suffer from complicated infections, including multi-organ and polymicrobial events. This pattern may be especially pronounced among patients exposed to infectious agents during catastrophic events like that of the Great East Japan Earthquake and the associated tsunami disaster. We report here on a patient who presented with Escherichia coli (E. coli) pneumonia in combination with fungal sinusitis and meningitis. A 73-year-old woman survived the tsunami that engulfed the Sanriku coast. By the time of hospital admission, the patient exhibited high fever, severe cough, and sputum production. Chest X-ray and CT scan showed consolidation in the left upper lobe. Administration of an antibacterial agent improved this pneumonia. However, the patient's consciousness was increasingly impaired. Brain CT showed the low-density lesions and partial high-density spot in the sinus, which suggests the fungal infection. MRI showed the inflammation in the sinus spread into the central nerve system. The examination of the cerebrospinal fluid showed the low glucose level, high mononuclear cell count, and highβ-D glucan level, the findings of which supported the diagnosis of fungal meningitis. Although the patient improved temporarily in response to combination treatment with anti-fungal agents, no further improvement was seen. In conclusion, this patient, who suffered from infections of pneumonia, sinusitis, and meningitis, presented a quite rare clinical progress. We propose that fungal infection should be taken into consideration in individuals who suffered near drowning, a profile expected to be frequent among tsunami survivors. PMID:22729220

    Full Text Available Introduction: There are suspended fungal spores in the air and in the nasal mucosa of adults, especially in areas with a humid climate. Several studies have revealed the role of fungi in the pathogenesis of chronic rhinosinusitis (CRS in recent years but it is a topic of controversy, especially in regions with low humidity. The aim of this study was to evaluate the prevalence of fungal species in intraoperative specimens from patients who underwent functional endoscopic sinus surgery (FESS for CRS in Hamadan, a high altitude region of Iran.                  Materials and Methods: In this prospective cross-sectional study specimens were obtained from 62 patients with a diagnosis of CRS according to clinical and computed tomography criteria who underwent endoscopic sinus surgery. During the functional endoscopic sinus surgery, specimens were collected from the nose and sinuses of patients and preserved in conical centrifuge tubes containing Sputolysin and chloramphenicol. The specimens were then plated on Sabouraud dextrose agar, Mycosel agar, Niger seed agar, and Chrom Agar/Candida plates and incubated at 30°C for up to 1 month. At the end of the incubation period the samples were evaluated microscopically to detect fungi and identify their genera and species. Results: The fungal cultures were positive in 16 out of 62 patients with CRS (25.8%. In order of frequency the fungal genera and species were: Aspergillus fumigatus (9, Aspergillus niger (3, Candida albicans (2, Penicillium sp. (1 and Cladosporium sp. (1. The percentage of positive cultures collected was higher in winter but the difference was not statistically significant compared to the rest of the year. Conclusion: Our data show that 25.8% of patients tested positive for the presence of fungi. The results strengthen the theory regarding the role of fungi in the pathogenesis of CRS even in areas with low humidity. Aspergillus was the most commonly isolated fungus.

  6. MRI in preoperative evaluation of chronic paranasal sinusitis - a comparison with CT

    International Nuclear Information System (INIS)

    Purpose: To determine the value of MRI in the preoperative evaluation of chronic paranasal sinusitis and to compare the results with CT and intraoperative findings. Method/Materials: 42 patients with clinical signs of chronic paranasal sinusitis underwent MRI after CT evaluation on one day, with subsequent functional endoscopic sinus surgery on the next day. Coronary CT was obtained with 5-mm slices and table-feed in the prone position, while MRI was performed in the supine position with coronary T2-TSE+pd and coronary and transverse HASTE, each with 5-mm slice thickness. Aquisition time in MRI was less than 8 minutes. Two radiologists reviewed the CT and MRI scans for signs of sinusitis and detection of anatomical landmarks. The results were correlated with the intraoperative findings. Results: MRI offered no artifacts of dental work and showed more often high quality pictures than CT. CT and MRI demonstrated a good correlation in the detection of mucosal pathologies (κ=0.46-0.87) and anatomic variants (κ=0.55-0.86). All important anatomical structures could be evaluated sufficiently with MRI for preoperative management. Both diagnostic tools showed an unsatisfactory correlation with intraoperative findings in the ethmoidal complex and maxillary sinus (τ=-0.08-0.3). (orig.)

  7. Isolated sphenoid sinusitis. An analysis of 15 cases

    International Nuclear Information System (INIS)

    Isolated sphenoid sinusitis is rare and difficult to diagnose. The difficulty arises because it is located in the deepest part of the nasal sinuses and the associated inflammation does not lead to typical symptoms of sinusitis. There are many important structures in the vicinity of the sphenoid sinus: the internal carotid artery, cavernous sinus and cranial nerves. Therefore, sphenoid sinusitis causes severe complications. From January 2003 to December 2007, we encountered 15 patients with isolated sphenoid sinusitis. Its incidence in all sinus diseases is 2.2%. Many patients complain of headaches, and they often visit neurologists or neurosurgeons. The pathological spectrum included 10 cases of bacterial sinusitis (5 acute sinusitis, 3 chronic sinusitis and 2 asymptomatic sinusitis), 3 fungal sinusitis, 1 mucocele and 1 retention cyst. When we diagnose isolated sphenoid sinusitis, CT and endoscopy are essential. CT becomes a more useful tool for performing a differential diagnosis when we independently change the window height and width. The endoscopic findings regarding draining from the sphenoethmoidal recess may indicate the severity of inflammation. A detailed observation with CT and endoscopy is the most important to accurately diagnose the pathology of isolated sphenoid sinusitis. (author)

    Full Text Available Introduction: Chronic suppurative otitis media (CSOM is defined as infection of the middle ear that lasts for >3 months and is accompanied by tympanic membrane perforation. The incidence is higher in developing countries, especially among the low socioeconomic strata of the society. Many authors have focused their attention on the bacterial flora of CSOM, but very little is known about the mycological aspects of these, the importance of which has been increasing in the recent years. Objective: The present study was aimed to speculate the etiological fungal flora responsible for the cases of CSOM among patients who attended the Ear, Nose, and Throat Department of our hospital a tertiary care center in Uttarakhand. Materials and Methods: The total of 107 patients (both males and females who were clinically diagnosed with CSOM and were on any antibiotics (oral, topical or systemic for >14 days and still persisted with symptoms were included in this study. Results: Among the 107 cases of CSOM studied, fungi were isolated in 83 (77.57%. Majority of the patients were in second and third decades of life (62.62%. Of the 83 fungal culture positive cases, the predominantly isolated fungi were Aspergillus species (47%, Candida species (41%, and Penicillium species (9.6%. Among the Aspergillus, the predominant species were Aspergillus flavus (17 isolates and Aspergillus niger (12 isolates. Candida albicans (19 isolates and Candida tropicalis (9 isolates were the commonly isolated species of Candida. Conclusion: A definite search for fungal etiology is desirable in all cases of CSOM. Prolonged use of topical antibiotics or antibiotics-steroids ear drops may cause suppression of bacterial flora and the subsequent emergence of fungal flora. This probably increases the incidence of fungal superinfection. Otologists should suspect mycotic otitis media in patients with continuous otorrhea and who do not respond to the antibacterial treatment.

    2015-03-01

    Odontoma is a mixed odontogenic hamartoma involving both epithelial and mesenchymal tissues. If left untreated, it can lead to complications in certain conditions. Here is a rare presentation of an extensive complex odontoma in maxillary sinus pushing third molar near the orbital floor causing transient diplopia in upward gaze occasionally and chronic sinusitis. Although odontomata are not uncommon and are familiar to practitioners, but some aggressive cases may cause problematic sequelae. Even postoperative complications may result if oral surgeons are not aware of the potential pitfalls associated with the surgical removal of large maxillary antrum odontomata. This article reports a rare presentation which can be considered unique because when obstruction of sinus drainage is evident, serious complications such as orbital infections, epidural and subdural empyema, meningitis, cerebritis, cavernous sinus thrombosis, brain abscess and death can occur. It also addresses points and pitfalls concerning surgery to remove odontoma. PMID:25848139

    Full Text Available Abstract Introduction Chronic pyelonephritis is associated with progressive renal scarring and occurs, most of the time, in patients with major anatomical anomalies, including urinary tract obstruction, calculi, renal dysplasia or vesicoureteric reflux. We report the computed tomography imaging findings of a patient with chronic pyelonephritis appearing as a renal sinus mass. To our knowledge, it is the first time that such a case has been published in the literature. Case presentation We present a case of a 68-year-old woman who underwent a computed tomography scan of the abdomen in the work-up for recently diagnosed hypertension. A non-enhancing left renal sinus mass was detected extending to the para-aortic space. The initial diagnosis was that of a tumor of the collecting system. Nephro-ureterectomy was performed and the pathology results revealed changes of chronic pyelonephritis. Conclusion Chronic pyelonephritis presenting as a renal sinus mass is reported for the first time in the literature. This may lead to the conclusion that diagnostic ureteropyeloscopy and biopsy should be performed prior to radical surgery for possible upper tract urothelial tumors.

    Background. The management of complex pilonidal sinus disease (PSD) with multiple pits on and beside the natal cleft is variable, contentious, and problematic. Wide excision of the sinus and reconstruction of the defect using different flap techniques have become more popular in recent years. Case Report. We report a case with a complex chronic PSD to which we applied primary closure after S-shaped wide excision. The patient's postoperative course was uneventful, and at the end of one-year followup he is now disease-free and comes for routine checkups. Conclusion. The simplicity of the technique and the promising results support the applicability of the S-shaped wide excision in chronic bilaterally extended large PSDs. Further studies entailing large patient populations are needed to reach a definite conclusion. PMID:24987541

    Background Chronic sinusitis is one of the most common chronic diseases involving different age groups. Because the nature and etiology of chronic sinusitis are not completely known, there is not any standard treatment for this disease. It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage. In this research, intra-oral radiation of low-level laser has been described and implemented for the first time. Suggested hypotheses about the efficacy of this type of radiation (intra-oral) in treating chronic maxillary sinusitis includes this fact that the depth of maxilla’s vestibule is also the floor of maxillary sinus and sinus discharges collect in this area because of gravity effect. Therefore, with considering suitable radiation angle, this area gets the most benefits of laser’s anti-inflammatory effects. Material and Methods In this study, 20 patients with chronic maxillary sinusitis were included. They were assessed before and after treatment. Treatment plan was performed in 8 sessions every other days using low-level diode laser with 810 nm. Snot-22 questionnaire and rhinomanometry were used for evaluating patients. Changes of signs and symptoms were recorded in questionnaire every session and 6 months after treatment. Friedman and Wilcoxon tests were used for data analyses. In this study, P value < 0.05 was considered statistically significant. Results All variables and all symptoms of patients were improved using intra-oral low-level laser and this improvement was statistically significant (P value<0.05). There was also significant decrease in nasal airway resistance and significant increase in air flow (P value<0.05). Six month after treatment completion, there was no significant difference between the results of completion and the results of 8th treatment session (P value< 0.05). Conclusions Using intra-oral low-level laser is a suitable way to treat patients with chronic maxillary

  16. Sinonasal carcinoma presenting as chronic sinusitis and sequential bilateral visual loss

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Sinonasal undifferentiated carcinoma-related rhinogenic optic neuropathy is rare and may lead to visual loss. To the best of our knowledge, this is the first report of bilateral sequential visual loss induced by this etiology. It is important to differentiate between chronic sinusitis and malignancy on the basis of specific findings on magnetic resonance images. Surgical decompression with multidisciplinary therapy, including steroids, chemotherapy, and radiotherapy, is indicated. However, no visual improvement was noted in this case, emphasizing the rapid disease progression and importance of early diagnosis and treatment.

  17. Expression of cysLT1 and cysLT2 Receptor in Chronic Hyperplastic Eosinophilic Sinusitis

    International Nuclear Information System (INIS)

    Elevated production of cysteinyl leukotrienes (cysLTs) from sinus tissues and abundant sinus eosinophils are characteristic features of chronic hyperplastic eosinophilic sinusitis (CHS). CysLTs exert their action through G-protein-coupled receptors named cysLTs receptor type I (cysLT1R) and type II (cysLT2R). These expressions of cysLT receptors in the sinus mucosa have yet to be clarified and the relationship between eosinophilia and the expression of these receptors remains obscure. We compared the expressions of cysLT1R and cysLT2R in the sinus mucosa in patients with CHS, non-eosinophilic chronic sinusitis (NECS), and control sinus tissues; and analyzed the correlation between the expression of CysLTRs and the presence of sinus eosinophils by immunohistochemistry and real-time PCR. A significantly higher percentage of eosinophils expressing cysLT2R protein was observed in patients with CHS compared with NECS and controls. In addition, cysLT2R mRNA expression in CHS was significantly higher than in NECS and controls. Furthermore, a positive correlation was observed between cysLT2R mRNA expression and the number of infiltrated eosinophils. In contrast, the cysLT1R mRNA expression did not differ significantly among these groups. The effect of cysLTs on sinus eosinophils may be mediated through the cysLT2R in patients with CHS. These results may suggest the therapeutic benefit of cysLT2R antagonists in CHS

  18. Diagnosis of chronic rhino sinusitis in patients with cystic fibrosis: correlation between anamnesis, nasal endoscopy and computed tomography

    International Nuclear Information System (INIS)

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    International Nuclear Information System (INIS)

    Objective: To search for the mechanism of 32P-colloid perfusion therapy in the animal models of chronic maxillary sinusitis. Methods: 32P-colloid were injected into the male sheep maxillary sinuses of the animal-models of chronic maxillary sinusitis in different dosage group. The changes of bacteria and mucosael pathomorphology were observed by periodic germiculture and pathology in 1,3,6 months after injection. Results: After 32P-colloid perfusion therapy, the amounts of bacterial species and chronic phlogistic cells were remarkable reduced, and the structure of cilia cells did not change. The curable rate was 83.3% in 6 months. There were remarkable difference in groups. Conclusions: 32P-colloid was provided with antibiosis and reducing chronic phlogistic responses. The authors had found the optimal dose of 32P-colloid perfusion in the maxillary sinuses through the study. The curable rate of single dose of 32P-colloid perfusion in the maxillary sinuses was higher than other therapy, 32P-colloid perfusion was simple and convenient. There was high selectivity of 32P in the target organ, when there was no effect on other important organs through radiobiological measurement. (authors)

    2010-05-01

    Full Text Available Abstract Introduction The presence of a foreign body in the nose is a relatively uncommon occurrence. Many unusual foreign bodies in the nose have been reported in the literature, but no case of a nasal packing occurring as a foreign body in the nasal cavity for a prolonged time has been found. Case presentation We describe a unique case of the largest foreign body left in situ in the nasal cavity for over 10 years. Our patient was a 71-year-old Caucasian man with diabetes. Because of this, he was at high risk of developing complications from the foreign body and the chronic sinusitis. Amazingly, though, the foreign body had not caused any symptoms on our patient for many years, except for nasal discharge during the last few years. To the best of our knowledge, this is the first case in the literature of such a large intra-nasal foreign body described in an adult without mental illness and without trauma that remained in situ for such a long time. Conclusion Undoubtedly, even illnesses with no complications could prove difficult for clinicians to diagnose. Clinicians should recognize the underlying causes that are responsible for the symptoms of chronic sinusitis and a unilateral nasal discharge should be assumed to be caused by an intra-nasal foreign body until proven otherwise.

  1. The relation between mastoid pneumatization and sigmoid sinus position in chronic otomastoiditis

    International Nuclear Information System (INIS)

    If significantly influenced by chronic otomastoiditis(COM), mastoid pneumatization and the position of the sigmoid sinus affect the operative procedure and postoperative complications in middle ear surgery. We evaluated mastoid pneumatization and sigmoid sinus position, and their relationship in COM, especially its during onset. Using temporal bone CT and referring to any relevant medical records, we retrospectively analyzed 107 cases of COM and 49 cases of normal ear. The total case load comprised an adult group, aged above 16 years [100 cases of COM (M:F=46:54, mean age = 45 years), and 42 cases of normal ear, (M:F=20:22, mean age = 44 years)], and a childhood group, aged less than 16 years [7 cases of COM (M:F=4:3, mean age = 8.4 years), and 7 cases of normal ear (M:F=4:3, mean age = 7 years)]. We determined the thickness of the mastoid bone by measuring the shortest distance between the outer cortex of this bone and the deepest border of the sigmoid sinus; the depth of the sigmoid sinus; and the degree of mastoid pneumatization and sclerosis. Fifty-three patients whose medical history clearly included the onset of otomastoiditis were divided into a child-onset group and an adult-onset group, and the relationship between the onset of otomastoiditis and the thickness of the mastoid bone was compared between the two groups. The mean axial thickness of the mastoid bone was 9.672±2.745 mm in COM and 12.430±3.027 mm in normal ear. The difference was statisfically significant (ρ < 0.0001). The mean depth of the sigmoid sinus was 7.557±1.868 mm in COM and 7.591±2.315 mm in normal ear, with no statistically significant difference. In the childhood group, the mean axial thickness of the mastoid bone was 8.672±2.978 mm in COM and 11.778±3.087 mm in normal ear. This difference was statistically significant (ρ < 0.05). In the adult group, the corresponding figures were 9.742±2.731 mm in COM and 12.538±3.041 mm in normal ear, a difference which was also

  2. Transcoronary sinus administration of autologous bone marrow in patients with chronic refractory stable angina

    International Nuclear Information System (INIS)

    Purpose: Based on our preclinic studies with autologous unfractionated bone marrow (AUBM) via coronary sinus with transitory occlusion, a clinic study in patients with chronic stable angina was designed. The objectives were to evaluate safety, tolerance and feasibility. Methods and materials: A multicenter prospective study with inclusion and exclusion criteria defined by an Independent Clinical Committee was carried out. Fourteen patients underwent transcoronary sinus administration of freshly aspirated and filtered AUBM (60-120 ml). Safety and tolerance were evaluated. Feasibility was evaluated with Seattle Angina Questionnaire (SAQ), Canadian Cardiovascular Society (CCS) angina classification (baseline-Day 180), myocardial perfusion (baseline-Day 90) with independent core laboratory and coronary angiography (baseline and Day 30). Results: There were no changes in the safety and tolerance parameters. Preliminary clinical efficacy at Day 180 disclosed a significant improvement of 38%, evaluated by the SAQ. The CCS angina classification shows that the mean angina class was 3.0±0.55 at baseline and improved to 2.0±0.00 at Day 180 (P<.001). Semiquantitative radionuclide perfusion imaging (core lab) showed a significant improvement at Day 90 in 13/14 patients, with a mean improvement of 24% at rest (P<.01) and 33% at stress (P<.05). Coronary angiography showed more collateral vessels in 9/14 patients. Conclusions: We can conclude that AUBM via coronary sinus with transitory occlusion is tolerable and safe. Significant improvement in the myocardial perfusion at Day 90 and in the quality of life at Day 180 was observed

    Fungal infections of the lung are uncommon and mainly affect people with immune deficiency. There are crucial problems in the diagnosis and treatment of this condition. Invasive pulmonary aspergillosis and candidiasis are the most common opportunistic fungal infections. Aspergillus species (spp.) are saprophytes molds that exist in nature as spores and rarely cause disease in immunocompetent individuals. In patients with immune deficiency or chronic lung disease, such as cavitary lung disease or bronchiectasis, Aspergillus may cause a variety of aspergillosis infections. Here we present a case of a 57-year-old patient without immunodeficiency or chronic lung disease who was diagnosed with endotracheal fungus ball and chronic fungal infection, possibly due to Aspergillus. Bronchoscopic examination showed a paralyzed right vocal cord and vegetating mass that was yellow in color, at the posterior wall of tracheal lumen. After 3 months, both the parenchymal and tracheal lesions were completely resolved. PMID:27418930

    Chronic mucocutaneous or invasive fungal infections are generally the result of primary or secondary immune dysfunction. Patients with autosomal recessive CARD9 mutations are also predisposed to recurrent mucocutaneous and invasive fungal infections with Candida spp., dermatophytes (e.g., Trichophyton spp.) and phaeohyphomycetes (Exophiala spp., Phialophora verrucosa). We study a consanguineous family of Turkish origin in which three members present with distinct clinical phenotypes of chronic mucocutaneous and invasive fungal infections, ranging from chronic mucocutaneous candidiasis (CMC) in one patient, treatment-resistant cutaneous dermatophytosis and deep dermatophytosis in a second patient, to CMC with Candida encephalitis and endocrinopathy in a third patient. Two patients consented to genetic testing and were found to have a previously reported homozygous R70W CARD9 mutation. Circulating IL-17 and IL-22 producing T cells were decreased as was IL-6 and granulocyte/macrophage colony-stimulating factor (GM-CSF) secretion upon stimulation with Candida albicans. Patients with recurrent fungal infections in the absence of known immunodeficiencies should be analyzed for CARD9 gene mutations as the cause of fungal infection predisposition. PMID:26961233

  6. Maxillary Sinus mucormycosis mimicking sinus malignancy

    International Nuclear Information System (INIS)

    Mucormycosis is an opportunistic fulminant fungal infection in diabetic and immunocompromised patients. The infection is acquired in the nose and paranasal sinuses by the inhalation of the fungal spores. We report of a case of maxillary sinus mucormycosis in a 32-years-old non diabetic woman. She had right side facial pain, headache, unilateral right side nasal obstruction, and post nasal discharge (PND) for five years. Nasal endoscopy revealed pus and granulation tissue, and semi-black middle turbinate in right side nasal cavity. Computed tomography showed bone erosion and a large soft tissue mass similar to sinus carcinoma in maxillary sinus with extension into the ethmoidal sinus. She underwent functional Endoscopic sinus surgery. Macroscopically, the specimen consisted of multiple tissue fragment 0.8-1 cm. Microscopic findings included an inflammatory cells and deposited fungal elements (mucormycosis). So in the paranasal sinus and nasal cavity mass, mucormycosis should be included in the differential diagnosis, especially in the non diabetic and young patients. (author)

  8. Hyperostosis of the maxillary sinus wall in aspergillosis: is it a characteristic finding

    International Nuclear Information System (INIS)

    To determine whether the wall thickening of the maxillary sinus is a characteristic finding in aspergillosis. In 103 patients, including 26 with aspergillosis, 21 with inverted papilloma (IP), and 56 with unilateral chronic sinusitis, the thickness of the maxillary sinus wall was determined by CT scanning. All cases were proven pathologically, and patients with a history of previous surgery of bone destruction were excluded. Two neuroradiologists retrospectively reviewed the CT scans using bone window settings for sinus wall hyperostosis and the presence of intrasinus calcification. Thickening of the maxillary sinus wall was assessed visually in a semiquantitative manner, and graded as 'none' (absence of thickening), 'mild' (thickening of up to 1.5 times), or moderate ot severe(over 1.5 times thicker than normal contralateral sinus wall at its thickest point). Moderate to severe wall thickening was found only in patients with aspergillosis (21/26, 80.8%). Mild wall thickening was seen in two patients with aspergillosis (2/26, 7.7%), in 12 of 21 with IP (57.1%), and in 5 of 56 with chronic maxillary sinusitis (8.9%). Most cases of chronic maxillary sinusits( 51/56,91.1%), 9/21 IP cases (42.9%), and 3/26 cases of aspergillosis (11.5%) showed no thickening of the maxillary sinus wall. Calcifications were found in 18 patients with aspergillosis (69.2%), in no patient with IP (0%), and in one with chronic maxillary sinusitis (1.8%). We suggest that 'moderate to severe' wall thickening of the maxillary sinus is the characteristic finding of aspergillosis. Although various sinonasal diseases can cause bone change, CT findings of hyperostosis of the maxillary sinus and intrasinus calcification are very helpful in differentiating fungal sinusitis from other types of chronic inflammatory lesions

    2016-01-01

    Background: Chronic granulomatous invasive fungal rhinosinusitis (CGIFRS) is a rare disease. The underlying immune responses that drive the development of CGIFRS, as opposed to successful pathogen clearance and controlled inflammation, are not currently known. Objective: To characterize the immune responses associated with CGIFRS. Methods: In addition to a battery of basic investigations, more in-depth immunologic testing involves ex vivo whole-blood stimulation with the polyclonal T-cell mitogen phytohemagglutinin and fungal antigens with interleukin (IL) 12, was undertaken to investigate cell-mediated immune responses associated with CGIFRS. Results: Ex vivo whole-blood stimulation with the polyclonal T-cell mitogen phytohemagglutinin and fungal antigens with IL-12 identified reduced interferon gamma and increased IL-17A levels within the supernatant, which indicated increased in vivo T-helper (Th)17 responses and impaired Th1 responses compared with healthy controls. Conclusion: These findings suggest that the development of CGIFRS may be associated with an abnormally exaggerated host Th17 response, which caused failure to clear the fungal pathogen with refractory fungal infection of mucosal membranes, resulting in chronic tissue inflammation.

    Duggal, Praveen; Wise, Sarah K

    2013-01-01

    Invasive fungal rhinosinusitis (IFRS) is a disease of the paranasal sinuses and nasal cavity that typically affects immunocompromised patients in the acute fulminant form. Early symptoms can often mimic rhinosinusitis, while late symptoms can cause significant morbidity and mortality. Swelling and mucosal thickening can quickly progress to pale or necrotic tissue in the nasal cavity and sinuses, and the disease can rapidly spread and invade the palate, orbit, cavernous sinus, cranial nerves, skull base, carotid artery, and brain. IFRS can be life threatening if left undiagnosed or untreated. While the acute fulminant form of IFRS is the most rapidly progressive and destructive, granulomatous and chronic forms also exist. Diagnosis of IFRS often mandates imaging studies in conjunction with clinical, endoscopic, and histopathological examination. Treatment of IFRS consists of reversing the underlying immunosuppression, antifungal therapy, and aggressive surgical debridement. With early diagnosis and treatment, IFRS can be treated and increase patient survival. PMID:23711036

    There are numerous surgical approaches for oro-antral-fistula (OAF) closure. Secondary sinus disease is still considered by many experts a relative contra indication for primary closure. To describe a single-stage combined endoscopic sinus surgery and per-oral buccal fat pad (BFP) flap approach for large OAF causing chronic maxillary sinusitis. The records of all the patients with OAF and chronic manifestations of secondary rhinosinusitis that were treated between 2010 and 2013 in our tertiary care medical center were reviewed. The exclusion criteria were: OAF 5 mm, resolved sino-nasal disease, OAF secondary to malignancy, recurrent fistula, medical history that included radiotherapy to the maxillary bone and age halitosis (n = 6, 13.3%) and pain (n = 5, 12.2%). Surgical complications included local pain (n = 2, 4.4%), persistent rhinitis (n = 2, 4.4%) and synechia (n = 1, 2.2%). One patient required revision surgery due, to an unresolved OAF. The OAF of all the other 44 patients (97.8%) was closed after the first procedure and the paranasal sinuses on the treated side were completely recovered. The mean follow-up time for the group was 7.6 ± 4.3 months (7-21 months), and no untoward sequelae or recurrence were reported. Combined, one step, endoscopic Maxillary sinus drainage together with per-oral BFP flap approach is an efficacious surgical approach for safe closure of OAFs that are complicated with secondary chronic maxillary sinusitis.

The effects were still present after 8 years with SF-36 physical component score 0.38 (0.10; 0.65 and mental component score 0.74 (0.49; 1.00. Conclusion This observational study showed relevant improvements that persisted for 8 years in patients seeking homeopathic treatment because of sinusitis. The extent to which the observed effects are due to the life-style regulation and placebo or context effects associated with the treatment needs clarification in future explanatory studies.

  19. Facial osteomyelitis as complication of chronic sinusitis in hemophiliac-AIDS patients - scintigraphic evaluation with technetium-99m-MDP and Gallium-67

    International Nuclear Information System (INIS)

    In the paper six cases of facial osteomyelitis as a complication of chronic sinusitis in hemophiliac-AIDS patients are reported. Osteomyelitis was suggested by an increasing of erythrocyte sedimentation rate. The diagnosis was confirmed by a positive 99m Tc MDP scintigraphy. The patients were submitted to clinical treatment. The erythrocyte sedimentation rate and 67-gallium citrate scans were used in the follow-up of the therapy. Three patients had negative gallium after three weeks of organism-specific antibiotic therapy; in two patients the gallium scintigraphy remained positive. One patient did not undergo the radionuclide scan for this clinical conditions. These results suggest that MDP scans showed higher sensitivity and specificity in detection of bone disease in chronic sinusitis. Gallium scans appeared to be valuable tool in the follow-up of the infection. There are no reports in the literature of osteomyelitis as a complication of chronic sinusitis in AIDS patient. (author)

    AIM: To investigate the early diagnostic methods of bacterial and fungal infection in patients with chronic cholestatic hepatitis B.METHODS: One hundred and one adult in-patients with chronic hepatitis B were studied and divided into 3 groups:direct bilirubin (DBil)/total bilirubin (TBil)≥0.5, without bacterial and fungal infection (group A, n=38); DBil/TBil <0.5, without bacterial and fungal infection (group B, n=23);DBil/TBil≥0.5, with bacterial or fungal infection (group C,n=40). The serum biochemical index and pulse rate were analyzed.RESULTS: Level of TBil, DBil, alkaline phosphatase (ALP)and DBil/ALP in group A increased compared with that in group B. The level of ALP in group C decreased compared with that in group A, whereas the level of TBil, DBil and DBil/ALP increased (ALP: 156±43, 199±68, respectively,P<0.05; TBil: 370±227, 220±206, respectively, P<0.01;DBil: 214±143, 146±136, respectively, P<0.01; DBil/ALP:1.65±1.05, 0.78±0.70, respectively, P<0.001). The level of DBil and infection affected DBil/ALP. Independent of the effect of DBil, infection caused DBil/ALP to rise (P<0.05).The pulse rate in group A decreased compared with that in group B (63.7±6.4, 77.7±11.4, respectively, P<0.001),and the pulse rate in group C increased compared with that in group A (81.2±12.2, 63.7±6.4, respectively, P<0.001).The equation (infection=0.218 pusle rate +1.064 DBil/ALP -16.361), with total accuracy of 85.5%, was obtained from stepwise logistic regression. Pulse rate (≥80/min) and DBil/ALP (≥1.0) were used to screen infection. The sensitivity was 62.5% and 64.7% respectively, and the specificity was 100% and 82.8% respectively.CONCLUSION: Bacterial and fungal infection deteriorate jaundice and increase pulse rate, decrease serum ALP and increase DBil/ALP. Pulse rate, DBil/ALP and the equation (infection=0.218 pusle rate+1.064 DBil/ALP-16.361) are helpful to early diagnosis of bacterial and fungal infection in patients with chronic

    Rhinosinusitis affects approximately 20% of the population, and the chronic rhinosinusitis represents over 90% of all cases of rhinosinusitis. The correct diagnosis is important for proper treatment and to predict its evolution. This study presents two cases of atypical frontal sinus disease, which the follow-up revealed a diagnosis of fungal rhinosinusitis. The present study aims to describe the cases of two patients with atypical lesions on the left frontal sinus; the treatment options, surgical approach, results, diagnosis and follow-up are further discussed. A significant increase in the reported cases of fungal rhinosinusitis has been seen in the last two decades, justified by the use of broad-spectrum antibiotics and steroids, as well as the increased number of immunocompromised individuals. This study reports the cases of two patients with a type of fungal rhinosinusitis named "fungal ball", characterized by a tangle of hyphae in the sinuses without tissue invasion. The treatment included surgical removal of the fungal infectious process with aeration of the affected sinus, and the procedure was successfully performed in our patients.

The epidemic significance of CPNSR in Moscow and the RF was estimated, by analyzing the records available in the annual official statistical sources (Form No. 12.Results. The incidence of CPNSR in Moscow in the study period remains lower than those in the RF. Its prevalence among the population in the city and in the country as a whole shows a significant increasing trend. Among the adolescents in both Moscow and the RF, the incidence of CPNSR is higher than that in children and constitutes 24.4 and 31.6 versus 3.3 and 21.8 per 10,000 population, respectively. The childrenand adolescents in the RF are the highest risk groups in the incidence of CPNSR. In 2009, its prevalence rates in Moscow and the RF were 99.5 and 121.3 per 10,000, respectively; which were well above those in 2007 (81.2 and 117.5 per 10,000, respectively.Conclusion. The high incidence and prevalence rates for CPNSR remain high in all population strata in Moscow and the RF, which may be associated with decreased diagnostic alertness and inadequate treatment for upper airway diseases.

    A vast variety of nonstructural proteins have been studied for their key roles and involvement in a number of biological phenomenona. Interleukin-32 is a novel cytokine whose presence has been confirmed in most of the mammals except rodents. The IL-32 gene was identified on human chromosome 16 p13.3. The gene has eight exons and nine splice variants, namely, IL-32α, IL-32β, IL-32γ, IL-32δ, IL-32ε, IL-32ζ, IL-32η, IL-32θ, and IL-32s. It was found to induce the expression of various inflammatory cytokines including TNF-α, IL-6, and IL-1β as well as macrophage inflammatory protein-2 (MIP-2) and has been reported previously to be involved in the pathogenesis and progression of a number of inflammatory disorders, namely, inflammatory bowel disease (IBD), gastric inflammation and cancer, rheumatoid arthritis, and chronic obstructive pulmonary disease (COPD). In the current review, we have highlighted the involvement of IL-32 in gastric cancer, gastric inflammation, and chronic rhinosinusitis. We have also tried to explore various mechanisms suspected to induce the expression of this extraordinary cytokine as well as various mechanisms of action employed by IL-32 during the mediation and progression of the above said problems.

    Full Text Available Rhinosinusitis affects approximately 20% of the population, and the chronic rhinosinusitis represents over 90% of all cases of rhinosinusitis. The correct diagnosis is important for proper treatment and to predict its evolution. This study presents two cases of atypical frontal sinus disease, which the follow-up revealed a diagnosis of fungal rhinosinusitis. The present study aims to describe the cases of two patients with atypical lesions on the left frontal sinus; the treatment options, surgical approach, results, diagnosis and follow-up are further discussed. A significant increase in the reported cases of fungal rhinosinusitis has been seen in the last two decades, justified by the use of broad-spectrum antibiotics and steroids, as well as the increased number of immunocompromised individuals. This study reports the cases of two patients with a type of fungal rhinosinusitis named "fungal ball", characterized by a tangle of hyphae in the sinuses without tissue invasion. The treatment included surgical removal of the fungal infectious process with aeration of the affected sinus, and the procedure was successfully performed in our patients.

  11. Computed tomography of the paranasal sinus for endonasal sinus surgery

    International Nuclear Information System (INIS)

    In a retrospective study 170 computed tomographies recorded in patients with chronic sinus disease were evaluated. The extent of sinus disease and the involvement of the different paranasalsinuses were well seen. Up to now 50 patients have undergone surgical treatment. The coincidence of the preoperative CT with the intraoperative findings was about 90%. Anatomic particularities of the paranasal sinus in an individual patient may predispose to recurrent sinusitis or mean there is an increased risk of intraoperative complications. The main risk factors are a far lateral location of the posterior ethmoid cells (28.8%), a much lower position of the cibriform plate in comparison to the ethmoid roof (11.8%), and extensive lateral aeration of the sphenoidal sinus (1.2%). All patients should undergo CT scanning in coronal and axial planes prior to endonasal sinus surgery. This gives a guide for detection of inflammatory lesions and anatomic variations or anomalies, thus making it possible to prevent intraoperative complications. (orig.)

    Sinus pericranii is a rare anomaly that occurs when there is communication between the intracranial and extracranial venous systems. Accurate diagnosis is complicated because several other cranial masses can mimic sinus pericranii. Clinical, laboratory, and imaging assessments are all essential for identifying the anomaly. This article examines the comparative advantages of various diagnostic imaging modalities, current imaging techniques, and typical findings associated with sinus pericranii. Treatment and management options also are discussed. PMID:22461344

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    Full Text Available Introduction: Fungal ball of the sinuses is a not invasive infection that if characterizes for its chronicity, being the majority related with previous endodontic treatment. Affect mainly the breasts to maxillary; even so all the breasts can be involved. The main etiological agent is the Aspergillus spp. The computed tomography, had to characteristic the radiological presentations, suggests the diagnosis that is carried through definitively through histopathological analyses. The treatment standard-gold is the sinus surgery with average meatal antrostomy. Objective: Reporting two cases of fungal ball of the sinuses and to stand out important aspects of this pathology. Story of the Cases: Case 1 Patient of the feminine sex, 78 years old, presented itself with complaints of face pain has 6 months and previous history of endodontic treatment. To the physical examination it was evidenced purulent secretion presence in left average meatus. Ray X presented complete veiling of the breasts to maxillary left, while the computed tomography showed injury calcified in this place. Sinusotomy was become fulfilled that evolved well. Case 2 Patient of the feminine sex, 70 years old, looked attendance for history of sinusitis of repetition. To the physical examination no particularity was not perceived. The computed tomography, as well as the magnetic resonance, detected thickening of the mucous wall of the breasts to maxillary left, beyond a calcified mass. It was become fulfilled same sequence of treatment and the patient also evolved well. Final Considerations: The fungal infection must be considered in the patients who if present with chronic sinusitis, that they do not answer to the antibiotic use and that they possess history of endodontic manipulation.

    2006-01-01

    Full Text Available Background: Controversy still exists about the exact cause of pilonidal sinus either acquired or congenital, and also about what is the best surgical technique for the treatment of the disease. We successfully treated chronic pilonidal sinus with a new flap technique {N-shaped bilateral rotation flap} for closure of the defect. Materials and Methods: Thirty-two patients (30 men and two women were treated by eccentric elliptical excision of the diseased tissues down to the postsacral fascia and closure of the defect with our flap [which is a random pattern flap], then a closed suction drain was placed at the base of the wound, with its tip being brought out in the gluteal region at least 5 cm lateral to the lower end of the suture line. Results: All our patients healed completely without recurrence during a period of average follow-up of two years. Mean hospital stay was 1.5 days (range 1-5 days. Mean time to complete healing was 11.9 days (range 6-18 days. Mean time off work was 13.7 days (range 10-21 days. Two patients had wound infection and one patient a partial breakdown. The recurrence rate was 0%. Conclusions: A tension-free suture via bilateral rotation flaps with a good suction at the button of the wound for drainage of blood from the bottom of the wound is the key to the success of repair without recurrence.

    Full Text Available Objective. Determining the indications for osteoplastic frontal sinus obliteration (OFSO for the treatment of inflammatory frontal sinus disease. Study Design. Retrospective case series from a single tertiary care facility. Methods. Thirty-four patients who underwent OFSO for chronic frontal sinusitis ( and frontal sinus mucocele ( comprised our study group. Data reviewed included demographics, history of prior frontal sinus operation(s, imaging, diagnosis, and operative complications. Results. The age range was 19 to 76 years. Seventy percent of patients with chronic frontal sinusitis underwent OFSO as a salvage surgery after previous frontal sinus surgery failures, while 30% underwent OFSO as a primary surgery. For those in whom OFSO was a salvage procedure, the failed surgeries were endoscopic approaches to the frontal sinus (69%, Lynch procedure (12%, and OFSO outside this study period (19%. For patients with frontal sinus mucocele, 72% had OFSO as a first-line surgery. Within the total study population, 15% of patients presented for OFSO with history of prior obliteration, with a range of 3 to 30 years between representations. Conclusions. Osteoplastic frontal sinus obliteration remains a key surgical treatment for chronic inflammatory frontal sinus disease both as a salvage procedure and first-line surgical therapy.

    Summary Chromoblastomycosis is a chronic skin infection caused by the fungus Fonsecaea pedrosoi. Exploring the reasons underlying the chronic nature of F. pedrosoi infection in a murine model of chromoblastomycosis, we find that chronicity develops due to a lack of pattern recognition receptor (PRR) costimulation. F. pedrosoi was recognized primarily by C-type lectin receptors (CLRs), but not by Toll-like receptors (TLRs), which resulted in the defective induction of proinflammatory cytokines...

  8. Sinusitis with eosinophilic otitis media

    International Nuclear Information System (INIS)

    Eosinophilic otitis media is an intractable inflammation of the middle ear combined with bronchial asthma. According to a national epidemiological investigation on eosinophilic otitis media, it is assumed that eosinophilic otitis media are combined with sinusitis in about 74% of their cases. On the other hand, organizational images of eosinophilic otitis media and eosinophilic sinusitis are similar, and steroid therapy is effective together, and it is thought that they are involved in the idea of one airway one disease, but the details of sinusitis combined with the eosinophilic otitis media are unidentified. Therefore, we examined the kinds of the sinusitis combined with eosinophilic otitis media. We diagnosed 18 cases (male: 2 cases, female: 16 cases) (average age: 54.6 years old) as eosinophilic otitis media according to the diagnostic criteria. And, by the CT views of a paranasal sinus, blood tests, existence of the nasal polyp, etc, we investigated the kinds of sinusitis combined with eosinophilic otitis media. It turned out that bronchial asthma was combined with eosinophilic otitis media in 17 of 18 cases (airway hypersensitivity did sthenia of one case, but the asthma did not yet developed), and 6 cases were combined with aspirin induced asthma (AIA), and 3 cases were combined with Churg-Strauss syndromes (CSS). 10 case (55.6%) of 17 eosinophilic otitis media were combined with eosinophilic sinusitis. And 4 cases (22.2%) of 17 eosinophilic otitis media were combined with chronic sinusitis, 4 cases (22.2%) of 17 eosinophilic otitis media were not combined with sinusitis. We concluded that eosinophilic otitis media was not always combined with eosinophilic sinusitis. The idea of one airway one disease was not applied to this examination. (author)

  9. Volumetric measurement of the maxillary sinus by coronal CT scan

    International Nuclear Information System (INIS)

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

  12. Pneumatisation of the maxillary sinus in normal and symptomatic children

    International Nuclear Information System (INIS)

    The pattern of pneumatisation and normal width of the maxillary sinus in 191 Nigerian infants and children whose age range was 6 months to 14 years was determined. Fifty-four percent of children with no respiratory tract or sinus infection had opaque maxillary sinus. A figure of 44.5% was obtained amongst children with suspected bronchopneumonia. Only 41.5% of suspected cases of sinusitis, acute and chronic middle ear disease had opaque sinus. The highest rate of sinus opacity was seen in children under 2 years who were asymptomatic. The mean maximal width of normally aerated sinus was 8.74 mm for children under 2 years, 16.5 mm for 3-6 years, 21.5 mm for 7-11 years and 25 mm for children 12 years and above. We conclude that maxillary sinus opacity in our experience is an unreliable index for the diagnosis of sinusitis in children. (orig.)

  14. CT and MR findings of mycotic infection of the paranasal sinus: Differentiation from sinonasal neoplasm

    International Nuclear Information System (INIS)

    When a soft tissue mass in the bony wall of the paranasal sinus is present. It is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific areas on CT. This is a report of four proven cases of fungal sinusitis, aspergillosis in 3 cases and mucormycosis in 1 case. All 4 patients had CT and one patient had MRI. On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI

    The coronary sinus (CS) has become a clinically important structure especially through its role in providing access for different cardiac procedures such as arrhythmia ablation, biventricular pacing and recently, percutaneous valvular interventions. Fluoroscopy with or without two-dimensional transesophageal echocardiography is the widely used method for guidance. A 78-year-old female patient undergoing percutaneous CARILLON mitral annuloplasty device therapy for chronic severe symptomatic mitral regurgitation. After insertion of the CS catheter through the right internal jugular vein, multiple trials for CS cannulation guided by fluoroscopy and two-dimensional transesophageal echocardiography were unsuccessful. So, real time three-dimensional zoom mode was used. Then, the volume was rotated to have the anatomically oriented enface view of the interatrial septum from the right atrial perspective. The CS ostium was identified adjacent to the eustachian valve. Then the catheter was reintroduced through the superior vena cava into the right atrium then easily navigated to cannulate the CS ostium. The position was confirmed by the fluoroscopically known course of the CS plus the pattern of the invasive pressure wave form. CS cannulation is not always feasible using fluoroscopy and/or two-dimensional Echocardiography guidance. Real time three-dimensional transesophageal echocardiography can be used to guide CS cannulation as it provides an anatomically oriented and informative enface view of the CS ostium. It can help reducing fluoroscopic radiation time. PMID:25231878

    Chronic granulomatous disease (CGD) is a rare genetic disorder in which phagocytes fail to produce superoxide because of defects in one of several components of the NADPH oxidase complex.

    2004-04-01

    Odontogenic sinusitis is a well-recognized condition and accounts for approximately 10% to 12% of cases of maxillary sinusitis. An odontogenic source should be considered in patients with symptoms of maxillary sinusitis who give a history positive for odontogenic infection or dentoalveolar surgery or who are resistant to standard sinusitis therapy. Diagnosis usually requires a thorough dental and clinical evaluation with appropriate radiographs. Common causes of odontogenic sinusitis include dental abscesses and periodontal disease perforating the Schneidarian membrane, sinus perforations during tooth extraction, or irritation and secondary infection caused by intra-antral foreign bodies. The typical odontogenic infection is now considered to be a mixed aerobic-anaerobic infection, with the latter outnumbering the aerobic species involved. Most common organisms include anaerobic streptococci, Bacteroides, Proteus, and Coliform bacilli. Typical treatment of atraumatic odontogenic sinusitis is a 3- to 4- week trial of antibiotic therapy with adequate oral and sinus flora coverage. When indicated, surgical removal of the offending odontogenic foreign body (primary or delayed) or treatment of the odontogenic pathologic conditions combined with medical therapy is usually sufficient to cause resolution of symptoms. If an oroantral communication is suspected, prompt surgical management is recommended to reduce the likelihood of causing chronic sinus disease. PMID:15064067

    Background Long-term maintenance of sinus rhythm after successful conversion of chronic atrial fibrillation (CAF), often ameliorates patients' symptoms, reduces the risk of ischemic stroke and improves cardiovascular hemodynamics. This prospective study aims to evaluate the long-term efficacy and safety of very low-dose amiodarone (100 mg daily) for the maintenance of sinus rhythm after successful direct-current (DC)cardioversion in patients with CAF and rheumatic heart disease (RHD) post intervention.Methods This study was a randomized prospective trial. One day after successful DC cardioversion (remained normal sinus rhythm) in patients with CAF and RHD post intervention for more than six months and adequate anticoagulation, all were randomly administered either amiodarone 200 mg daily in group A or amiodarone 100mg daily in group B.Results A total of 76 patients (40 men and 36 women) were examined from February 1998 to December 1999.The mean age of the patients was (66±10) years, and the mean follow-up was (67±8) months (range 61 to 84months). Actuarial rates of the maintenance of sinus rhythm were similar in the two groups after 5 years of follow-up. Four patients (11%) in group A but none in group B experienced significant adverse effects that necessitated withdrawal of amiodarone. No death occurred during the study period.Conclusion A very low dose of amiodarone results in adequate long-term efficacy and is safe for maintaining sinus rhythm in patients with CAF and RHD post intervention after successful DC cardioversion.

  10. Helical computed tomography of the paranasal sinuses in children: evaluation of sinus inflammatory diseases

    International Nuclear Information System (INIS)

    We conducted a retrospective analysis of 71 selected pediatric patients, aged 1 to 7 years, which were submitted to helical computed tomography examination of the paranasal sinuses in the period between March, 1997 and April, 1998 due to recurrent acute sinusitis and chronic sinusitis. Clinical and helical computed tomography findings were compared by evaluating the pneumatization of the paranasal sinuses, ostiomeatal complexes, anatomic variants, the status of mucosal surface and lesion extension. The most common CT findings were total or partial opacification of one or more paranasal cavities (92.9%), followed by mucosal thickening (67.6%). In the majority of cases there was association between sinusitis and ostiomeatal obstruction. Anatomic variants were identified from the age of one year. The most common anatomic variant was septonasal deviation (14.1%) that was associated to sinusitis in about 71% of the patients. (author)

    Highlights: •Atrial Fibrillation (AF) may affect CCTA image quality. •We compare the results of single heartbeat CCTA in subjects with chronic AF and in sinus rhythm. •Single heartbeat CCTA may be feasible also in subjects with cAF and HR <72 bpm. •In cAF patients with heart rate higher than 72 bpm, CCTA has more movement-associated artefacts. •Mean effective dose of single heartbeat CCTA in cAF group was higher than in sinus rhythm one. -- Abstract: Objectives: To evaluate image quality and radiation dose of single heartbeat 640-slice coronary CT angiography (CCTA) in patients with chronic Atrial Fibrillation (cAF) in comparison with subjects in normal sinus rhythm. Methods: A cohort of 71 patients with cAF was matched with 71 subjects in normal sinus rhythm (NSR) and HR ≤ 65 bpm using a matched by propensity analysis. All subjects underwent a single heartbeat CCTA with prospective gating. In subjects with cAF, we manually established the acquisition of data only from a single heartbeat. Mean effective dose and image quality, with both objective and subjective measures, were assessed. Results: 96.4% of all segments in the cAF group had diagnostic image quality. The rate of subjects with at least one non-diagnostic segment was 14% and 2.8% (p = 0.031) in the cAF and NRS groups, respectively. In the cAF group, the percentage of patients with at least one non-diagnostic segment for acquisition HR ≤ 72 was 1.8% (1/55), and it did not significantly differ from the NSR group (2.8%; 2/71) (p = 1.0). Objective quality parameters did not show a statistically significant difference between the two groups. The mean effective dose was 4.24 ± 1.24 mSv in the cAF group and 2.67 ± 0.5 mSv in the sinus rhythm group (p < 0.0001) with an increase by 59% in the cAF group with respect to the SNR group. Conclusions: A single heartbeat acquisition protocol with a 640-slice prospectively ECG-triggered CT angiography may be feasible in patients with cAF and HR below 72

    Chronic active Epstein-Barr virus infection (CAEBV) is characterized by chronic infectious mononucleosis-like symptoms associated with very high viral load, as assessed by quantitative polymerase chain reaction. We present an unusual case in a French woman who was followed up over 25 years with cutaneous and sinus lymphoproliferation. This white woman presented with a long history of recurrent cutaneous necrotic papules of the skin, which started during childhood and healed spontaneously with depressed scars. The lesions spread to the left maxillary sinus and were associated with hepatomegaly and splenomegaly with no other visceral locations. Pathological examination of the skin and sinus revealed a dermal monoclonal T-cell lymphoproliferative disorder, CD7(+) and CD20(-) , with no epidermotropism. T-cell receptor rearrangement was positive, showing the monoclonality from the first biopsy. This T-cell proliferation was positive for EBV-encoded small RNA and was associated with a high EBV viral load. Since then, the patient has been in good health, despite a permanently high EBV viral load. Hydroa vacciniforme (HV)-like lymphoma and natural killer/T-cell lymphoma were discussed, but none really fit our case. Natural killer cell lymphoma was ruled out because of the indolent course, but sinus lesions do not exist in HV-like lymphoma. A therapeutic approach is difficult because of the coexistence of viral infection and monoclonal T-cell proliferation. Chemotherapy is not efficient and induces immunosuppression, which may worsen the prognosis. Although rituximab may have an immunomodulatory function, it was not effective in our case. PMID:26148205

    In the paper six cases of facial osteomyelitis as a complication of chronic sinusitis in hemophiliac-AIDS patients are reported. Osteomyelitis was suggested by an increasing of erythrocyte sedimentation rate. The diagnosis was confirmed by a positive {sup 99m} Tc MDP scintigraphy. The patients were submitted to clinical treatment. The erythrocyte sedimentation rate and 67-gallium citrate scans were used in the follow-up of the therapy. Three patients had negative gallium after three weeks of organism-specific antibiotic therapy; in two patients the gallium scintigraphy remained positive. One patient did not undergo the radionuclide scan for this clinical conditions. These results suggest that MDP scans showed higher sensitivity and specificity in detection of bone disease in chronic sinusitis. Gallium scans appeared to be valuable tool in the follow-up of the infection. There are no reports in the literature of osteomyelitis as a complication of chronic sinusitis in AIDS patient.

    Pilonidal sinus is a chronic inflammatory disease commonly observed in the sacrococcygeal region. The authors report a patient of a pilonidal sinus in a rare location-the lateral orbital region. The authors' patient was misdiagnosed with an epidermal cyst, and the subsequent incomplete excision of the sinus tract led a pilonidal sinus with a high morbidity resulting in the destruction of bone tissue in the lateral orbital wall. It was, therefore, crucial to accurately diagnose and treat before the infection progressed through the bone and caused osteomyelitis. PMID:27391513

  6. A Possible Association of Staphylococcus Enterotoxin B-induced Asthma and Sinusitis

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    In order to gain insight into a possible association between chronic sinusitis and asthma,85 patients with sinusitis and asthma underwent functional endoscopic sinus surgical treatment and serum antibodies and cytokines were measured. The results showed that 51 out of 85 patients with high serum anti-Staphylococcus enterotoxin B (SEB) antibody before treatment obtained satisfactory results for both sinusitis and asthma. The high level of Th2 cytokine IL-4 was down regulated tothe levels of normal controls after sinus surgery. Thirty-four out of 85 patients did not show high serum anti-SEB antibody before sinus surgery and did not show much improvement in their asthmatic symptoms although sinusitis symptoms were resolved by sinus surgery. It was concluded that bacterial superantigen SEB (in the sinuses) might play a crucial role in the pathogenesis of lower airway hypersensitivity.

  8. Maxillary Antrolith: A Rare Cause of the Recurrent Sinusitis

    Directory of Open Access Journals (Sweden)

    Vijendra Shenoy

    2013-01-01

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

  10. Sinusitis: imaging findings before and after treatment

    International Nuclear Information System (INIS)

    Full text: Learning objectives: To present the possibilities of Computed Tomography (CT) as a gold standard for investigation of inflammatory sinunasal diseases. The role of CT is very important in acute rhinosinuitis when sign and symptom suggest complication and in chronic sinusitis, especially before endonasal sinus surgery, for postoperative assessment and in cases of recurrences. As this method allows optimal differentiation of the air, bone and soft tissues it is able to achieve an exact visualization of a particular anatomic structures. The best representation in coronal plane of ostiomeatal unit OMU/maxillary sinus ostia, infundibulum, hiatus semilunaris, and the middle nasal turbinate and lateral nasal wall, and in axial plane of the relation: ethmoidal cells:orbit and sphenoidal sinus:internal carotid artery, are one of the biggest advantages of CT. This examination displayed not only the regional anatomy and the spread of the inflammation in the sinuses and adjacent regions, but also aided the operator in his choice of surgical approach. As CT is the best imaging modality in the evaluation of the paranasal sinuses, the question about the radiation dose became very important. The dose was reduced to protect the eye lenses, with no loss of image quality and no signification noise increase. There are many different techniques and recommendations for the CT study of the sinuses, but still no definite idea about the optimal technique for investigation in this region. This is the aim of the lecture - to develop an optimal study for preoperative and postoperative CT examination of the paranasal sinuses

    2016-05-01

    Patients who present with severe intractable apparently idiopathic fatigue accompanied by profound physical and or cognitive disability present a significant therapeutic challenge. The effect of psychological counseling is limited, with significant but very slight improvements in psychometric measures of fatigue and disability but no improvement on scientific measures of physical impairment compared to controls. Similarly, exercise regimes either produce significant, but practically unimportant, benefit or provoke symptom exacerbation. Many such patients are afforded the exclusionary, non-specific diagnosis of chronic fatigue syndrome if rudimentary testing fails to discover the cause of their symptoms. More sophisticated investigations often reveal the presence of a range of pathogens capable of establishing life-long infections with sophisticated immune evasion strategies, including Parvoviruses, HHV6, variants of Epstein-Barr, Cytomegalovirus, Mycoplasma, and Borrelia burgdorferi. Other patients have a history of chronic fungal or other biotoxin exposure. Herein, we explain the epigenetic factors that may render such individuals susceptible to the chronic pathology induced by such agents, how such agents induce pathology, and, indeed, how such pathology can persist and even amplify even when infections have cleared or when biotoxin exposure has ceased. The presence of active, reactivated, or even latent Herpes virus could be a potential source of intractable fatigue accompanied by profound physical and or cognitive disability in some patients, and the same may be true of persistent Parvovirus B12 and mycoplasma infection. A history of chronic mold exposure is a feasible explanation for such symptoms, as is the presence of B. burgdorferi. The complex tropism, life cycles, genetic variability, and low titer of many of these pathogens makes their detection in blood a challenge. Examination of lymphoid tissue or CSF in such circumstances may be warranted. PMID

  15. Correlation of x rays and computed tomography in paranasal sinus diseases

    International Nuclear Information System (INIS)

    Objective of the study was to evaluate the diagnostic yield of X-rays taking CT scan as gold standard in acute and chronic sinusitis. Study Design: Validation study. Place and Duration of study: The study was conducted in the Radiology Department CMH Rawalpindi, from 1 Aug, 2007 to 31 July, 2008. Patients and Methods: This study involved 95 patients of both genders above 18 years of age who presented with acute and chronic sinusitis in ENT department of CMH Rawalpindi. Patients were referred to Radiology department for their X-ray paranasal sinuses (PNS) and findings were correlated with CT scan. Results: Out of 43 patients clinically suspected of having acute sinusitis, x ray PNS shows imaging findings of acute sinusitis in 26 (60%) patients while 17 patients were having normal x-ray PNS. When CT scan was performed to correlate the findings, it showed 30 (69%) patients were having acute sinusitis while 13 (30%) patients had no imaging findings of sinusitis. Out of 48 patients, X ray PNS showed chronic sinusitis in 26 (54%) patients and 22 patients were having normal x ray PNS. While CT scan showed 33 (68%) patients were having chronic sinusitis and 15 patients were normal. Four patients either didn't reported for their CT scan or they refused to get their CT scan done. Conclusion: Plain radiographs were once the mainstay of diagnosis of sinus disease and now have been replaced by high-resolution CT scan for the evaluation of acute and chronic sinusitis. Plain radiographs do not allow adequate evaluation of the osteomeatal complex or of the sphenoid and ethmoid sinuses because of overlapping anatomic structures. CT is the modality of choice for imaging acute and chronic sinusitis and provides the surgeon with important information of the osteomeatal complex and normal variations, preoperatively. (author)

  18. Chronic bacterial pneumonia in free-ranging Eastern box turtles (Terrapene carolina carolina).

    Science.gov (United States)

    Evans, R H

    1983-10-01

    Chronic bacterial pneumonia was diagnosed in two free-ranging Eastern box turtles. Mucoid exudation into the upper respiratory tract and bilateral, caseating pneumonia were seen grossly. Microscopically, chronic, active inflammation with pseudomembrane formation occurred in the nasal sinuses and lungs while caseating granuloma-like structures were also observed in alveoli and associated infundibulae. Since viral, protozoal or fungal agents could neither be demonstrated in tissue sections by light or electronmicroscopy, nor could they be isolated in vitro, the gram-negative bacteria, seen in large numbers within the lesions and easily cultured in vitro, were considered the etiologic agents of this disease.

  14. Helical CT of the paranasal sinuses prior to bone marrow transplantation

    International Nuclear Information System (INIS)

    Purpose: To investigate the clinical necessity of CT of the paranasal sinuses before bone marrow or peripheral blood stem cell transplantation. Patients and methods: 80 patients with malignant disease underwent coronal CT of the paranasal sinuses prior to transplantation to exclude sinusitis. Results: CT revealed sinusitis requesting therapy in 17/80 patients (21%). Patients with leukaemia and non-Hodgkin lymphoma were significantly more affected. Chronic sinusitis was found in two patients, mucosal swelling not requesting therapy in 22, and normal findings in 39. Conclusion: CT of the paranasal sinuses is advised in patients suffering haemoblastoses with an increased risk of infectious complications during the transplantation phase, because pathological findings can be expected in 21% of the patients. Diagnosis and therapy of an infectious focus within the paranasal sinuses is especially important prior to allogenous bone marrow transplantation. (orig.)

    Mucormycosis is a highly invasive, devastating and usually fatal fungal infection of the sinuses, brain, or lungs that occurs primarily in people with immune disorders. Despite advances in diagnosis and treatment, a high mortality still exists. We present a middle aged diabetic male with this serious fungal infection involving nose, paranasal area and adjacent periorbital regions with a high risk of progressing further towards the dura mater. He was promptly diagnosed and managed with serial surgical debridements with systemic antifungals and was later fitted with a nasal prosthesis. (author)

  6. MRI of maxillary sinuses

    International Nuclear Information System (INIS)

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

  7. CT features in second cancers of the maxillary sinus

    International Nuclear Information System (INIS)

    Five patients with a second maxillary cancer (squamous cell carcinoma), which developed 6 to 17 years after initial treatment for the first cancer on the opposite side, were compared with 21 control cases with a primary cancer on the basis of computed tomography (CT) findings. Generally, the second cancer was found at an earlier stage. The specific CT findings of early sinus carcinoma were uneven soft tissue distribution in the antrum and tumor permeation with bone fragments remaining at the original tumor site. These findings may be helpful for distiguishing this cancer from benign chronic sinusitis and/or other malignant sinus disease. The pterygoid process, medial bony wall, and ethmoid sinus had a tendency to be spared in most of the 5 patients with second maxillary cancer compared to the 21 control cases. (orig.)

  15. The importance of venous hypertension in the formation of dural arteriovenous fistulas: a case report of multiple fistulas remote from sinus thrombosis

    International Nuclear Information System (INIS)

    Various hypotheses have been reported concerning the pathogenesis of dural arteriovenous fistulas (DAVFs). However, it is still controversial whether sinus thrombosis or venous hypertension has a greater influence on the formation of DAVFs. We present a rare case of multiple DAVFs that developed after sinus thrombosis. Chronic venous hypertension secondary to sinus thrombosis in the left transverse-sigmoid sinus induced the multiple DAVFs, including one in the right cavernous sinus, which was remote from the occluded sinus. This case indicates the importance of venous hypertension in the formation of DAVFs. (orig.)

Voriconazole is rapidly becoming the drug of choice for all fungal keratitis because of its wide spectrum of coverage and increased penetration into the cornea.Implementation: Repeated debridement of the ulcer is recommended for the penetration of topical medications. While small, peripheral ulcers may be treated in the community, larger or central ulcers, especially if associated with signs suggestive of anterior chamber penetration should be referred to a tertiary center.

    Pilonidal sinus is a chronic inflammatory condition owing to the subcutaneous trapping of hair. Most commonly it is found in the sacrococcygeal region (natal cleft) but rarely it is found on the penis with very few cases reported in the literature worldwide. We are reporting a case of a pilonidal sinus growing on the distal penile shaft with the sinus opening to the mucosal layer of the foreskin, in a young and fit patient. The cyst was removed with a circumcision and found to contain hair. This was confirmed by histology as a pilonidal sinus cyst. PMID:23697453

    Full Text Available Abstract Introduction Fungal infection of the paranasal sinuses is an increasingly recognized entity both in immunocompetent and immunocompromised individuals. Treatment has been via use of either surgical or medical modalities, or a combination of the two. Here, we present a case of utilization of intra-antral application of an anti-fungal agent in the management of recurrent fungal sinusitis in an indigent Nigerian patient. Case presentation We present the case of a 30-year-old West African Yoruba man, an indigent Nigerian clergyman, who presented to our facility with a history of recurrent nasal discharge (about one year, recurrent nasal blockage (about five months, and right facial swelling (about one week. After intra-nasal antrostomy for debulking with a systemic anti-fungal agent, our patient had a recurrence after four months. Our patient subsequently had an intra-antral application of flumetasone and clioquinol (Locacorten®-Vioform® weekly for six weeks with improvement of symptoms and no recurrence after six months of follow-up. Conclusions We conclude that topical intra-antral application of anti-fungal agents is effective in patients with recurrent fungal maxillary sinusitis after surgical debulking.

    Hyperprolactinemia is a rare entity in the pediatric population. The most common causes of hyperprolactinemia include drug use, hypothyroidism and renal insufficiency, though rarely a pituitary or sellar mass is discovered. We present an immunocompetent pediatric patient who presented with gynecomastia and was found to have hyperprolactinemia. Imaging showed a sphenoid mass and referral was made for a pituitary tumor. The mass was not a pituitary tumor and he was formally diagnosed with allergic fungal sinusitis and treated surgically. There are no previous reports of allergic fungal rhinosinusitis causing pituitary dysfunction in a pediatric patient. We also present a brief review and discussion of the treatment of allergic fungal sinusitis. PMID:26768883

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

    Full Text Available Pilonidal sinus usually develops in the sacrococcygeal area or other hair-bearing areas. However, it can present at some other sites with varied presentations and can mimic like other infective pathologies which are more common in that area. It has also been described as an occupational hazard in barbers, especially when presented interdigitally. Occupational pilonidal sinuses tend to occur even in non-hair-bearing areas where there is no presence of individual’s own hair. Pilonidal sinus occurs in many areas of the body such as web of fingers, penis shaft, axilla, intermammary area, groin, nose, neck following trauma during shaving, clitoris, sternum, suprapubic area, occiput, prepuce, chin, periungual region, breast, face or navel. Sporadic incidences of implantation of pilonidal sinus have been reported. The disease is mostly observed in hairdressers, but it has also been reported sporadically in other professions, as male sheep shearer, dog groomer, slaughter men or milker of cows. Short customers’ hairs that penetrate the supple interdigital skin of the hands produce barber’s disease. Though there are only a few reports about these peculiar sinuses in the available literature, they should be suspected in any chronically discharging, non-healing sinus or wound. A clinical suspicion of malignant transformation or affection with tuberculosis in the endemic area should also be kept in mind to avoid any delay in the treatment and the outcome of the disease.

  4. Venous sinus stenting for pseudotumour cerebri with venous sinus stenosis

    International Nuclear Information System (INIS)

    Objective: To explore the relation between venous sinus stenosis and pseduotumour cerebri and to discuss the efficacy and strategy of venous sinus stenting for its treatment. Methods: Venous sinus stenting was performed in a total of 9 patients with pseudotumour cerebri accompanied by dural sinus stenosis. The clinical data, including the clinical presentations, intracranial pressure, angiographic findings, pressure of dural sinus,methods of treatment and the therapeutic results, were retrospectively analyzed. Results: Bilateral disc edema was seen in all patients. The pressure gradient in the lateral sinuses was obviously high before stenting (22.67±7.25)mmHg in all patients and a reduction in intra-sinus pressure and pressure gradient was also found (5.78±3.77)mmHg. The symptoms associated with intracranial hypertension were gradually improved or disappeared in two weeks after the placement of the stent in all cases, and the intracranial pressure dropped evidently (12.78±5.97)cm H2O. Vision was improved in 7 cases at three months, whereas it remained poor in 2 cases despite normalized intracranial pressure. There was no other permanent procedure-related morbidity. The patients were followed up for 3 months to 5 years, and no recurrence developed. Conclusion: Lateral sinus stenting is an effective method for the treatment of pseudotumour cerebri with dural sinus stenosis. (authors)

    2015-04-01

    Our objective was to estimate the burden of fungal disease on the island of Ireland, as part of a coordinated project estimating the global burden. Published epidemiology data describing fungal infection in Ireland were identified. Population and underlying disease data were collected for 2010 and a structured set of assumptions were applied to estimate burden of fungal disease based on immunosuppression, chronic disease, and other demographic information indicating predisposition to fungal infection. From Ireland's population of 6.4 million, we estimate 117, 000 patients develop significant fungal disease each year. By far the most common fungal disease is recurrent Candida vaginitis, with an estimated 95, 000 episodes annually (3000 per 100 000 women). Other fungal diseases which may be less well recognized are severe asthma with fungal sensitization and allergic bronchopulmonary aspergillosis, with estimated episodes per year of 11, 700 and 9000, respectively (182 and 140 per 100, 000 population, respectively). The model also estimates 450 episodes of invasive aspergillosis, 200 of chronic pulmonary aspergillosis, 600 of oesophageal candidiasis and 450 of candidaemia per year (7, 3, 9 and 6 episodes per 100, 000 population, respectively). This is, we believe, the first attempt to estimate the burden of fungal disease in our population and provides a basis for estimating its impact on human health and resource use. PMID:25596121

    Paranasal sinus cancers are rare diseases, accounting for about 5% of all head and neck malignancies. The variety of histological types and the overlapping pathological features with other entities constitute difficulties in pathologic interpretation, often requiring a skilled interpretation or a second opinion. Treatment of locally advanced disease relies on surgery and radiation therapy for operable disease, with a possible role for systemic treatment in selected histologies within a multimodal approach; unresectable paranasal sinus cancers are generally treated with a combination of radiotherapy and chemotherapy. The employment of high conformal radiation techniques, such as Intensity Modulated Radiation Therapy orcharged particle therapy, proton or carbon ion therapy may improve outcome and reduce late effects. Surgical treatment has evolved due to the progressive application of transnasal endoscopic techniques for naso-ethmoidal malignancies and due to innovative reconstructive techniques after resection of cancers of the maxillary sinus. Because of the rarity and complexity of this disease, multicenter trials represent an urgent need to improve prognosis and to reduce treatment-related effects. PMID:26520459

  9. Radiology of chronic diseases of the ankle joint

    International Nuclear Information System (INIS)

    The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or

    This report was to show the radiographic appearances of the fungus ball in a paranasal sinus and to emphasize the scan area of cone beam computed tomography (CBCT) to detect the calcification in the paranasal sinus. A seventy four-year-old woman visited our department for the implant rehabilitation at both maxillary posterior edentulous region. Pre-operative radiographic examinations including the panoramic, CBCT, and multidector CT images were taken. An opacification in the right maxillary sinus was observed on the multiplanar image of CBCT, however the pre-determined scan area of CBCT in this report hardly showed the calcifications at the central portion of the maxillary sinus. The opacification in the maxillary sinus could be misdiagnosed as chronic maxillary sinusitis if the calcification of fungus ball was not simultaneously detected. The scan area of pre-operative CBCT needs to be enough to scan the paranasal sinus from top to bottom.

    The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child. The child presented with an acute onset of significant visual impairment and headache. His vision gradually improved after trans-nasal sphenoidotomy and drainage of the sinus content with return of complete normal baseline vision after 2 months. (orig.)

    2015-12-01

    Expanded indications for cardiac resynchronization therapy and the increasing incidence of cardiac implantable electronic device infection have led to an increased need for coronary sinus (CS) lead extraction. The CS presents unique anatomical obstacles to successful lead extraction. Training and facility requirements for CS lead extraction should mirror those for other leads. Here we review the indications, technique, and results of CS lead extraction. Published success rates and complications are similar to those reported for other leads, although multiple techniques may be required. Re-implantation options may be limited, which should be incorporated into pre-procedural decision making. PMID:26596810

    International Nuclear Information System (INIS)

    Primary site control, anatomical site of failure, survival, and complications of treatment were determined in a retrospective review of primary maxillary sinus carcinoma. Sixty-one patients were treated by radiation followed by surgery and 35 by radiation alone. Primary tumor control was achieved in 69% of patients receiving combined treatment, 14% of patients treated with radiation alone, and 49% of all patients. Local control did not differ with histological type. Virtually all epidermoid and undifferentiated carcinoma recurrences occurred within 2 years, but 27% of adenocarcinomas recurred after 2 years

    The purpose of the present work is a clinical study of photodynamic therapy of maxillary sinusitis. 0.1%-Methylene Blue aqueous solution in combination with He-Ne laser irradiation (632.8 nm) have been used for treatment of maxillary sinus mucous of patients with acute and chronic maxillary sinusitis. The differences between the results of the treatment with dye and light versus treatment with a drug for every group of patients were statistically analyzed by Student’s t test. The efficacy of the photodynamic therapy was estimated with the use of the following criteria: the state of respiration, olfaction, duration of purulent discharge, reconstruction of transport function of ciliary epithelium, etc. The obtained results have shown that the photodynamic therapy is effective in comparison with conservative methods of treatment of the disease.

    2004-01-01

    Full Text Available Pilonidal sinus is a well-recognized condition that occurs most commonly in the sacrococcygeal area of younger men. It is hypothesized to be an acquired chronic inflammation condition due mainly to hair trapped beneath the surface. A pilonidal sinus in the sacrococcygeal region is associated with recurrent infection, abscess formation, cellulitis, fistulae, and rarely, squamous cell carcinoma. A pilonidal sinus of the penis is a rare entity. The association of a penile pilonidal cyst and Actinomyces is even more uncommon with only three cases reported previously. Two cases of pilonidal sinus are reported in this paper. One of the cases was associated with actinomycosis. Pilonidal sinus of the penis should be considered in the clinical and pathological differential diagnosis and has to be distinguished from balanoposthitis, epidermal cyst, and carcinoma. The knowledge about possible association with actinomycosis is important to ensure early treatment.

    Full Text Available Sinus node dysfunction (SND is commonly encountered in the clinic. The clinical phenotype ranges from asymptomatic sinus bradycardia to complete atrial standstill. In some cases, sinus bradycardia is associated with other myocardial conditions such as congenital abnormalities, myocarditis, dystrophies, cardiomyopathies as well as fibrosis or other structural remodeling of the SA node.1-8 Although there are many etiologies for symptomatic slow heart rates, the only effective treatment available today is the implantation of a pacemaker. The predominant ion channel currents contributing to the pacemaker activity in the sinoatrial node (SAN include currents flowing through hyperpolarization-activated, cyclic nucleotide-gated (HCN channels,9 L- type Ca, T- type Ca,10 delayed rectifier K,1112 and acetylcholine (ACh-activated13,14 channels. However, their relative contribution remains a matter of debate and the cellular mechanisms contributing to abnormal sinus node function leading to bradycardia are not fully elucidated. Sodium channel current (INa, encoded by SCN5A, is responsible for the cardiac action potential (AP upstroke and therefore has an important role in initiation and propagation of the cardiac action potential. Although it is largely absent in the sinus node, it plays an important role at the periphery of the sinus node in transmitting electrical activity from the sinus node to the rest of the atria.

  20. The development of maxillary sinus in children

    International Nuclear Information System (INIS)

    Developmental pattern of the maxillary sinuses was determined roentgenographically on Waters' view of 791 children ranged 11 months to 15 years of age. The width of maxillary sinuses increased according as age, the maximum width was measured in 14 ∼ 15 years. The maxillary sinuses developed inferolaterally, and the significant correlation was recognized between the width of maxillary sinuses, and neurocalvarium and facial bone. The incidence of opacity of maxillary sinuses were 50 % or more in children below 8 years of age, this means that opaque sinus are not necessarily abnormal. No significant correlation was recognized between the pattern of pneumatization and the size of the maxillary sinuses. (author)

    Mitchell, R B; Pereira, K D; Younis, R T; Lazar, R H

    1997-09-01

    Functional endoscopic sinus surgery (FESS) has become the surgical procedure of choice for the treatment of chronic sinusitis that is refractory to medical treatment. It has become routine to perform endoscopy in children under general anesthesia 2 to 3 weeks after FESS to facilitate examination and cleaning of the operative site. We compared the clinical outcome of 50 children who underwent FESS without a second-look endoscopy with 50 children who underwent a routine second look. Patients with systemic disease (cystic fibrosis, immotile ciliary syndrome, immunoglobulin deficiency) or undergoing a revision procedure were excluded from the study. The results show that the postoperative improvement in nasal obstruction, nasal drainage, and chronic cough was the same for both groups. We conclude that in the vast majority of children without systemic disease and not undergoing a revision procedure, a second endoscopic procedure may not offer any apparent advantage. PMID:9292615

    We aimed to determine the value of neutrophil-to-lymphocyte (NLR) ratio for prediction of recurrence in patients subjected to endoscopic sinus surgery. Higher neutrophil counts mean more chronic inflammation so the NLR value could show the inflammatory level resulting with higher incidence of recurrence. From January 2011 to March 2013, we performed a retrospective review of the complete blood count samples from 192 patients with chronic sinusitis who underwent endoscopic sinus surgery. The patients were divided into two groups based on the presence of nasal polyps. NLR and platelet-to-lymphocyte (PLR) ratios were analyzed. Receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value for significant differences in variables between the recurrence and non-recurrence groups. The ROC analysis results revealed an NLR cut-off of 3.13 and a PLR cut-off of 208.75. Our analysis revealed that NLR is an independent risk factor for recurrence of chronic sinusitis in patients subjected to endoscopic sinus surgery (p = 0.006), whereas the PLR was not a predictive factor for recurrence (p = 0.167). Our study revealed that the NLR could be used to predict disease recurrence before endoscopic sinus surgery. However, additional studies are needed to confirm these results. PMID:26285781

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

    The incidence and prevalence of fungal infections in Russia is unknown. We estimated the burden of fungal infections in Russia according to the methodology of the LIFE program (www.LIFE-worldwide.org). The total number of patients with serious and chronic mycoses in Russia in 2011 was three million. Most of these patients (2,607,494) had superficial fungal infections (recurrent vulvovaginal candidiasis, oral and oesophageal candidiasis with HIV infection and tinea capitis). Invasive and chronic fungal infections (invasive candidiasis, invasive and chronic aspergillosis, cryptococcal meningitis, mucormycosis and Pneumocystis pneumonia) affected 69,331 patients. The total number of adults with allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation was 406,082. PMID:26449508

  12. Radiotherapy in cancer of the paranasal sinuses

    International Nuclear Information System (INIS)

    Carcinomas of the paranasal sinuses are usually advanced when diagnosed and present a therapeutic challenge. During the period between February 1970 and June 1981 44 patients were treated. 22 received postoperative irradiation, seven in combination with chemotherapy. 18 patients were treated with radiation alone, eleven with concomitant chemotherapy. Four patients received preoperative irradiation, three in combination with chemotherapy. The three-year survival is 43% and the five-year survival 33%. For those 26 patients who were irradiated pre- or postoperatively with or without concomitant chemotherapy the five-year survival is 45%. We believe the patient will be afforded the greatest opportunity for cure with the combined efforts of the radiotherapist and the surgeon. The combination of chemotherapy and radiotherapy did not provide better results but increased acute and chronic toxicity of the therapy. (orig.)

    Full Text Available Background: Individual identification is a subtle concept and often one of the most important priorities in mass disasters, road accidents, air crashes, fires, and even in the investigation of criminal cases. Matching specific features detected on the cadaver with data recorded during the life of an individual is an important aspect in forensics, and can be performed by fingerprint analysis, deoxyribonucleic acid matching, anthropological methods, radiological methods and other techniques which can facilitate age and sex identification. Sinus radiography is one such method that has been used for determination of the sex of an individual. Hence, an attempt is being made to use the different dimensions of the maxillary sinus in the determination of sex using coronal and axial sections of plain computed tomography (CT scan. Materials and Methods: A total of 30 patients including 17 male and 13 female, visiting the Outpatient Department of the Mamata General Hospital were included as the study subjects. The dimensions of right and left maxillary sinuses of 30 subjects from plain CT were measured using SYNGO software and statistical analysis was done. Results: Sex determination using height, length, width, and volume of the maxillary sinus on both sides showed statistically significant results with a higher percentage of sexual dimorphism in the case of volume. Conclusion: Volume of the right maxillary sinus can be used as accurate diagnostic parameter for sex determination.

    Cancers of the paranasal sinuses are rare tumors, with treatment based on a multidisciplinary approach. Surgery and radiation therapy, possibly associated with chemotherapy are used to obtain 5 years specific survival rate of 60-70 %. Advances in radiotherapy, including the use of imaging for 3D conformal approach require precise knowledge of the radio-anatomy for this type of tumor to determine the different volumes of interest. Purpose of this study was to specify radio-anatomy and conformal radiation modalities for cancers of the sinuses, and is illustrated by a case report. (authors)

  20. CT findings of change of the maxillary sinus after caldwell-luc operation

    International Nuclear Information System (INIS)

    This study describes the CT findings of changes in the maxillary sinus after the Caldwell-Luc procedure. The maxillary sinus-related findings in 35 cases among 20 patients (17 cases in 10 males and 18 cases in 10 females) who had undergone the Caldwell-Luc procedure mean 14.6 years earlier were reviewed. CT scans were obtained in the axial and coronal planes, with 5mm thickness. By means of the T test, changes in the size of the bony wall of the maxillary sinus, as well as antral volume change, were compared with normal maxillary sinus group (41 male and 23 female cases). Males and females were compared separately, and surgical bony defect of naso-labial antrotomy and nasoantral window, fibro-osseous proliferation, compartmentation and mucosal thickening of the postoperative maxillary sinus were evaluated, as were findings of chronic or recurrent maxillary sinusitis and postoperative complications. Naso-labial antrotomy was clearly identified in 27 of 35 cases, and irregular bony surface in the remaining eight, as were 27 bony defects and one irregular bony margin among a total of 28 cases of nasoantral window. Due to shortening of the height of the orbit, reductions in maxillary width, nasoantral communication width and anteroposterior diameter of the maxilla, and widening of the width of the inferior meatus, the maxillary sinus tended to become hypoplastic and centripetally contracted. Reduced cavitary volume of the maxillary sinus was noted (p less than 0.05), and fibro-osseous proliferation (n=3D29), compartmentation (n=3D11), and mucosal thickening (n=3D22) of the postoperative maxillary sinus were also seen. There were findings of chronic sinusitis (n=3D22), as well as complications of postoperative mucocele (n=3D3) and oroantral fistula (n=3D2) of the maxillary sinus. The characteristic maxillary sinus-related findings seen after the Caldwell-Luc procedure are helpful in distinguishing postoperative change from recurrent paranasal diseases and resulting

    The clinical features were correlated with the coronal CT scan appearance of the paranasal sinuses of 49 patients who had received the Caldwell-Luc operation 16 to 58 years ago. The clinical diagnosis at the time of the CT scan was postoperative maxillary cyst in 22 patients, chronic sinusitis in 21 patients, trigeminal neuralgia in 3 patients, radicular cyst, postoperative ethmoid cyst and inverted papilloma in one patient each. The CT scans of the 91 operated maxillary sinuses showed obliterated cavity in 21 cases, small cavity in 46 cases, and cystic formation in 24 cases. The authors speculated that some maxillary sinuses which appeared in CT scans as small cavities might cause the clinical symptoms of postoperative maxillary cyst in the future. (author).

  2. Osteoma of paranasal sinuses of a horse

    International Nuclear Information System (INIS)

    A 2-year-old Quarter Horse gelding was examined for torticollis, facial protuberances over the frontal and maxillary sinuses, and persistent nasal discharge unresponsive to antibiotics. Radiograph revealed an osseous mass in the right paranasal sinuses. Histologic examination of the biopsied mass led to a diagnosis of osteoma. The mass was removed surgically in sections from the right frontal and maxillary sinuses through separate bone flaps, and sinuses were irrigated with saline solution for 8 days after surgery. Two weeks after surgery, radiography revealed small osseous opacities in the right paranasal sinuses. These opacities remained unchanged in radiographs obtained up to 23 months after surgery

    Purpose:.Cholesterol granuloma is usually associated with chronic middle ear disease..Involvement of the ethmoid sinus by cholesterol granuloma is rare..We describe a case with cholesterol granuloma of the posterior ethmoid sinus causing optic nerve compression..No previous reports were found in our review of the literature. Case report:.A 48-year-old man had impaired visual acuity and a relative afferent pupillary defect in the right eye. Fundus fluorescein angiography showed a swollen optic nerve head and optic disc leakage. Automated perimetry revealed a severe peripheral visual field defect with tunnel vision. Computerized tomography demonstrated an expansile,.isodense mass in the right posterior ethmoid sinus, remodeling of the bony walls of the right sphenoid sinus, and lateral displacement of the optic nerve in the right orbit..Compressive optic neuropathy caused by posterior ethmoid sinus lesion was diagnosed..A transnasal endoscopic exploration of the right ethmoid sinuses demon-strated a soft expansile cystic lesion with a thick yellow cap sule that filled the inside of the posterior ethmoid sinus. Brownish fluid with shiny crystals was drained by fine needle aspiration. The capsule was removed completely, and the mu-cociliary clearance of the sinus was reestablished..The patho-logic pictures confirmed the diagnosis of cholesterol granulo-ma, which included typical cholesterol clefts surrounded by inflammatory cells with focal multi-nucleated giant cells. Visu-al function fully recovered without recurrent lesions after a three-year follow-up. Conclusion:.Compressive optic neuropathy can be rarely caused by cholesterol granuloma in the posterior ethmoid si-nus. The visual prognosis may be good after transnasal endo-scopic decompression in such patients.

    2008-12-01

    Full Text Available Introduction: Mucormycosis is a rare opportunistic infection caused by Mucorales fungi, and the Rhizopus is the most common one (70% of the cases. It is an acute invasive fungal disease whose form is disseminated, cutaneous, pulmonary, gastrointestinal and rhino-orbitocerebral. The latter is the most common form and its symptoms comprise of unilateral sinusitis, fever and headache. Once established in the orbit the symptoms can be chemosis, diplopia and reduced vision. The infection can spread to the brain via the orbital apex, orbital arteries or via the cribriform plate. Mucormycosis is a medical emergency and the treatment consists of a surgery to an aggressive debridement and in the use of antifungal therapy. Despite the appropriate management, the mortality rate can reach 40% of the cases. One possible intracranial complication of Mucormycosis is the Cavernous Sinus Thrombosis which is a rare and fatal infective disease. The initial symptoms of Cavernous Sinus Thrombosis are headache, retro-orbital pain, periorbital edema, proptosis, diplopia and reduced vision. Case Report: We describe the case of 43-year-old woman with medical history of diabetes mellitus and use of immunosuppressant drugs after kidney transplantation. The patient developed Acute Bacterial Sinusitis and Rhino-orbitocerebral Mucormycosis associated with Cavernous Sinus Thrombosis.

  9. MRI feature of dural sinus arachnoid granulations

    International Nuclear Information System (INIS)

    Objective: To evaluate the MRI feature of dural sinus arachnoid granulations. Methods: All of the brain MRI studies in 2010 were retrospectively analyzed with emphasis on the distribution, size and signal characteristics of dural sinus arachnoid granulations. Results: Superior sagittal sinus was the most location followed by transverse sinus, straight sinus, and sigmoid sinus. The size ranged from 2 mm to 16 mm with the majority smaller than 8 mm in diameter. All of arachnoid granulations were hypointense on T1WI and FLAIR-weighted images slightly higher than cerebrospinal fluid, hyperintense on T2WI slightly lower than cerebrospinal fluid. Most of them did not enhance with contrast with the larger ones showing punctate or linear enhancement. Filling defects were seen on cerebral MRV. Conclusion: MRI characteristics of arachnoid granulations are reliable for distinguishing arachnoid granulations from other lesions of dural sinus. (authors)

    2014-12-01

    Full Text Available [english] Diseases of the pediatric nose and nasal sinuses as well as neighboring anatomical structures encompass a variety of pathologies, especially of inflammatory nature. Congenital disease, such as malformations and structural deviations of the nasal septum, as well as systemic metabolic pathologies affecting the nose and sinuses, rarely require medical therapy from an Otolaryngologist. The immunological function of the mucosa and genetic factors play a role in the development of disease in the pediatric upper airway tract, especially due to the constantly changing anatomy in this growth phase. Disease description of the nose and nasal sinuses due to mid-facial growth must also take developmental age differences (infant, toddler, preschool, and school age into account. Epidemiological examinations and evidence based studies are often lacking in the pediatric population.The wide range of inflammatory diseases of the nose and paranasal sinuses, such as the acute and chronic rhinosinusitis, the allergic rhinitis, and adenoid disease, play a role in the susceptibility of a child to infection. The susceptibility to infection depends on the pediatric age structure (infant, young child and has yet to be well defined. The acute rhinosinusitis in children develops after a viral infection of the upper airways, also referred to as the “common cold” in the literature. It usually spontaneously heals within ten days without any medical therapy. Antibiotic therapy is prudent in complicated episodes of ARS. The antibiotic therapy is reserved for children with complications or associated disease, such as bronchial asthma and/or chronic bronchitis. A chronic rhinosinusitis is defined as the inflammatory change in the nasal mucosa and nasal sinus mucosa, in which the corresponding symptoms persist for over 12 weeks. The indication for CT-imaging of the nasal sinuses is reserved for cases of chronic rhinosinusitis that have been successfully treated with

    Full Text Available Background. Mucocoele is histopathologically benign, cystic change of paranasal sinuses filled with mucoid contents, which with its growth is pressuring and destroying local bone walls. In only 3% of the cases it can be localized in maxillary sinuses. Etiology is unknown. Pyocoele develops by secondary infection. Case report. The male patient was 21 years old. His symptoms were runny nose with thick contents and heavy breathing on the right side of the nose, headaches, as well as the swelling of the right cheek. During clinical examination, the expansive change was found. It was completely closing the right side of the nose cavity. Computerized tomography (CT of paranasal cavities showed excessive expansion of the right maxillary sinus, with very thinned walls, while the cavity was filled with liquid. After antibiotics therapy, the radical operation of the right maxillary sinus was performed, based on Caldwell Luc method. The frontal wall was found to be extremely convex and thinned, while the medial wall was with dehiscention. The cystic change was extirpated. Mucocoele was proved by pathohistologic findings. Its wall was about 2 mm thick and it showed squamous metaplasia in the large part of the mucocoela epithel. In the submucosa fibrosis and inflammatory infiltrate was present. Postoperative follow-up was under control. Clinically and radiographycaly, six months after therapy, the patient does not have troubles. Conclusion. The rare localization of the mucocoeles in maxillary sinus can be explained with the width of the maxillary ostia. Infected mucocoeles, expanded to the local anatomical structures, should be operated on with classic radical surgical operation. .

    Full Text Available Carcinoma of the gallbladder is relatively uncommon but it is a very lethal disease. Gallbladder cancer constitutes 3−4% of all malignant lesions and ranks 5th among the digestive system tumors. Gallblader carcinoma is difficult to detect and diagnose in early stage because it usually has very slight symptoms or asymptomatic. It becomes increasingly necessary to make early diagnosis and identification of high-risk patient,as well as gallstone and history of chronic cholecystitis. Chronic cholecystitis is a chronic inflammation of gallbladder associated with cholelithiasis in more than 90% of cases. Cholelithiasis is one of the important etiological factors in carcinoma of the gallbladder. The histological examination of chronical cholecystitis shows the presence of Rokitansky Aschoff sinuses. Genetic approaches have proven that the components of inflammation such as primary inflammatory cytokines, interleukin-1 (IL-1, tumor necrosis factor (TNF, IL-6 and nuclear factor-kB (NF-kB play the key roles in carcinogenesis. The purpose of this study was to understand the correlation between the immunoexpression of NF-kB and Rokitansky Aschoff sinuses in chronic cholecystitis. The method was cross sectional of 30 cases of chronic cholecystitis from Department of Pathology Anatomy of Dr. Hasan Sadikin General Hospital Bandung/Faculty of Medicine Universitas Padjadjaran in 2010−2011. A section from 4 µm-thick paraffin embedded tissue of chronic cholecystitis was stained with hematoxylin eosin for histopatological evaluation and immunohistochemical using polyclonal NF-kB antibody. Immunoreactive cells was counted in five tumor areas of 400x field by light microscopy. The result showed a significant correlation between the immunoexpression of NFkB and Rokitansky Aschoff sinuses (p=0.000. In conclusion, there is a correlation between immunoexpression of NFkB and Rokitansky Aschoff sinuses because as the immunoexpression of NFkB increase, more Rokitansky

    Full Text Available Abstract Background Ectopic fat accumulation in the renal sinus is associated with chronic kidney disease and hypertension. The genetic contributions to renal sinus fat accumulation in humans have not been well characterized. Methods The present analysis consists of participants from the Framingham Offspring and Third Generation who underwent computed tomography; renal sinus fat and visceral adipose tissue (VAT were quantified. Renal sinus fat was natural log transformed and sex- and cohort-specific residuals were created, adjusted for (1 age, (2 age and body mass index (BMI, and (3 age and VAT. Residuals were pooled and used to calculate heritability using variance-components analysis in SOLAR. A genome-wide association study (GWAS for renal sinus fat was performed using an additive model with approximately 2.5 million imputed single nucleotide polymorphisms (SNPs. Finally, we identified the associations of renal sinus fat in our GWAS results with validated SNPs for renal function (n = 16, BMI (n = 32, and waist-to-hip ratio (WHR, n = 14, and applied a multi-SNP genetic risk score method to determine if the SNPs for each renal and obesity trait were in aggregate associated with renal sinus fat. Results The heritability of renal sinus fat was 39% (p Conclusions Renal sinus fat is a heritable trait, even after accounting for generalized and abdominal adiposity. This provides support for further research into the genetic determinants of renal sinus fat. While our study was underpowered to detect genome-wide significant loci, our candidate gene BMI risk score results suggest that variability in renal sinus fat may be associated with SNPs previously known to be associated with generalized adiposity.

  14. Atopic cough and fungal allergy

    Science.gov (United States)

    Fujimura, Masaki; Ohkura, Noriyuki; Makimura, Koichi

    2014-01-01

    We have shown that some patients presenting with chronic bronchodilator-resistant non-productive cough have a global atopic tendency and cough hypersensitivity without nonspecific bronchial hyperresponsiveness, abbreviated as atopic cough (AC). The cough can be treated successfully with histamine H1 antagonists and/or glucocorticoids. Eosinophilic tracheobronchitis and cough hypersensitivity are pathological and physiological characteristics of AC. Fungus-associated chronic cough (FACC) is defined as chronic cough associated with basidiomycetous (BM) fungi found in induced sputum, and recognition of FACC has provided the possibility of using antifungal drugs as new treatment strategies. Bjerkandera adusta is a wood decay BM fungus, which has attracted attention because of its potential role in enhancing the severity of cough symptoms in FACC patients by sensitization to this fungus. Before making a diagnosis of “idiopathic cough” in cases of chronic refractory cough, remaining intractable cough-related laryngeal sensations, such as “a sensation of mucus in the throat (SMIT),” which is correlated with fungal colonization, should be evaluated and treated appropriately in each patient. The new findings, i.e., the detection of environmental mushroom spores that should not be present in the human airways in addition to the good clinical response of patients to antifungal drugs, may lead to the development of novel strategies for treatment of chronic cough.

  15. Computerized Tomographic Study on the Paranasal Sinusitis

    International Nuclear Information System (INIS)

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

    To evaluate the MR findings of septic thrombosis of the cavernous sinus. Eleven MR images of six patients with septic cavernous sinus thrombosis obtained over a five-year period and proven clinically or radiologically were retrospectively reviewed. The contour and enhancement pattern of the cavernous sinus, changes in the internal carotid artery, orbit, pituitary gland and sphenoid sinus, and intracranial abnormalities were analyzed and compared with the findings of follow-up studies. In all six patients, contrast study revealed asymmetrical enlargement of the ipsilateral cavernous sinus and multiple irregular filling defects within it. Narrowing of the cavernous portion of the ipsilateral internal carotid artery was noted in five patients, upward displacement of the ipsilateral internal carotid artery in four, ipsilateral proptosis with engorgement of the superior ophthalmic vein in two, pituitary enlargement in five, and inflammatory change in the sphenoid sinus in six. Associated intracranial abnormalities included edema and enhancement in the meninx, temporal lobe, or pons adjacent to the cavernous sinus in four patients, hydrocephalus in one, and cerebral infarction in one. Follow-up MR imaging indicated that the extent of asymmetrical enlargement of the cavernous sinus, filling defects within it, as seen on contrast study, and enlarged pituitary glands had all decreased, without significant interval change. MR imaging is useful in the diagnosis of septic cavernous sinus thrombosis. Asymmetrical enlargement of the cavernous sinus, multiple irregular filling defect within it, as seen on contrast study, and changes in the internal carotid artery are characteristic findings.

    Full Text Available Background: Intracranial fungal masses (IFMs, granulomas and abscesses are uncommon lesions, infrequently encountered by neurosurgeons. There is no conclusive evidence on the ideal surgical management of these lesions. Aims: To summarize the recent literature on the prevalence, presentation, surgical management and outcome of patients with IFMs. Materials and Methods: The recent published literature was searched using standard search engines (PubMed and Google for articles reporting on the databases and surgical management of IFMs. A special effort was made to include publications from Indian centers. Results: Intracranial fungal masses were rarely seen even in major neurosurgical centers in India with a prevalence of around one to two per year. While most patients with IFM have immunosuppressed states, nearly 50% of patients with IFMs (especially in India have no obvious predisposing causes and are apparently immunocompetent. The clinical presentation could be categorized into three groups: 1. Involvement of the cranial nerves 1 to 6 with orbital and nasal symptoms. 2. Focal neurological deficits due to involvement of any part of the neuraxis; and 3. "Stroke-like" presentation with sudden onset of hemiparesis. Based on the presence or absence of radiological evidence of paranasal sinus disease, IFMs were classified into two types: 1. Rhinocerebral type; 2. Purely intracranial type that was further divided into a. intracerebral or b. extracerebral forms. Aspergillus species was the commonest fungal organism causing IFMs but a number of other fungi have been reported to cause IFMs. Surgery for IFMs can be of different types, namely 1. Stereotactic procedures; 2. Craniotomy; 3. Shunt surgery; and 4. Treatment of fungal aneurysms. Generally, radical surgery is advocated for IFMs but there is no unanimity regarding the radicality of the excision especially for the rhinocerebral form of the disease. Surgery should always be followed by antifungal

    The frontal sinus recess consists of anatomically narrow passages that are prone to stenosis in endonasal frontal sinus surgery for chronic sinus disease. Over the past 100 years, diverse frontal sinus stents have been developed and evaluated in clinical and animal studies. However, superinfection, formation of granulations tissue, stent dislocation and late stenosis of the duct have remained challenges and subject of debate in the literature. Currently developed biodegradable materials, including rare earth-containing magnesium alloys are promising candidates for application as temporary implant materials. The Mg 2 % wt Nd alloy (MgNd2) was used to design a nasal stent that fit the porcine anatomy. In the current study, we evaluate biocompatibility, biodegradation and functionality of a frontal sinus stent in 16 minipigs over 6 months. Intraoperative endoscopy revealed free stent lumen in all cases. Blood examination and clinical examinations indicated no systematic or local inflammation signs. The histopathology and elements analysis showed a very good biocompatibility. The μ-computed tomography-based volumetric analysis showed substantial stent degradation within 6 months. Our MgNd2 based stent appears to be a promising, solid basis for the development of a frontal sinus stent for clinical use. PMID:26341887

  1. Ganglia of the tarsal sinus: MR imaging features and clinical findings

    International Nuclear Information System (INIS)

    Purpose: To analyze MR imaging and clinical findings associated with ganglia of the tarsal sinus. Materials and methods: In a record search, ganglia of the tarsal sinus were retrospectively identified in 26 patients (mean age 48 ± 16 years), who underwent MR imaging for chronic ankle pain. Images were reviewed by two radiologists in consensus for size and location of ganglia, lesions of ligaments of the ankle and the tarsal sinus, tendon abnormalities, osteoarthritis, osseous erosions and bone marrow abnormalities. Medical records were reviewed for patient history and clinical findings. Results: Ganglia were associated with the interosseus ligament in 81%, the cervical ligament in 31% and the retinacula in 46% of cases. Signal alterations suggesting degeneration were found in 85%, 50% and 63% in case of the interosseus ligament, the cervical ligament and the retinacula, respectively. Scarring of the anterior talofibular ligament and the fibulocalcaneal ligament was found in 68% and 72% of the patients, respectively, while only 27% of the patients recalled ankle sprains. Ganglia at the retinacula were highly associated with synovitis and tendinosis of the posterior tibial tendon (p < 0.05). Conclusion: All patients with ganglia in the tarsal sinus presented with another pathology at the ankle, suggesting that degeneration of the tarsal sinus may be a secondary phenomenon, due to pathologic biomechanics at another site of the hind foot. Thus, in patients with degenerative changes of the tarsal sinus, one should be alerted and search for underlying pathology, which may be injury of the lateral collateral ligaments in up to 70%.

  3. Mucocele-like lesions of the sphenoid sinus with hypointense foci on T2-weighted magnetic resonance imaging

    International Nuclear Information System (INIS)

    Lesions limited to the sphenoid sinus are relatively rare, and are obscure with respect to symptoms and physical findings. The differential diagnosis of isolated sphenoid sinus disease includes bacterial sinusitis, fungal infection, granulomatous inflammation, mucocele, and tumors. Magnetic resonance imaging (MRI) can provide information that closely reflects the composition of the tissues, sometimes permitting differentiation between pathologically distinct lesions showing similar density by computed tomography. We describe two cases involving mucocele-like lesions of the sphenoid sinus where preoperative MRI revealed a focus of hypointensity within the lesions. In both patients the sphenoid sinus was opened by a transnasal endoscopic approach, and diseased tissue corresponding to the hypointense area was removed under direct endoscopic vision. Histopathological diagnosis revealed colonies of Aspergillus in one case and necrotic granulation tissue without fungus in the other. We concluded that MRI is a crucial part of preoperative evaluation and that the transnasal endoscopic approach represents a safe and effective method for treating nonmalignant isolated sphenoid sinus disease.

  4. Coronal CT of the paranasal sinuses before and after functional endoscotic sinus surgery

    International Nuclear Information System (INIS)

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

  5. Sinus Node and Atrial Arrhythmias.

    2016-05-10

    Although sinus node dysfunction (SND) and atrial arrhythmias frequently coexist and interact, the putative mechanism linking the 2 remain unclear. Although SND is accompanied by atrial myocardial structural changes in the right atrium, atrial fibrillation (AF) is a disease of variable interactions between left atrial triggers and substrate most commonly of left atrial origin. Significant advances have been made in our understanding of the genetic and pathophysiologic mechanism underlying the development and progression of SND and AF. Although some patients manifest SND as a result of electric remodeling induced by periods of AF, others develop progressive atrial structural remodeling that gives rise to both conditions together. The treatment strategy will thus vary according to the predominant disease phenotype. Although catheter ablation will benefit patients with predominantly AF and secondary SND, cardiac pacing may be the mainstay of therapy for patients with predominant fibrotic atrial cardiomyopathy. This contemporary review summarizes current knowledge on sinus node pathophysiology with the broader goal of yielding insights into the complex relationship between sinus node disease and atrial arrhythmias.

    2013-04-01

    Full Text Available Endodermal sinus tumor (or Yolk Sac tumor of the vagina is a rare malignant germ-cell tumor which is seen exclusively in children younger than 3 years of age. We report two cases of endodermal sinus tumor of the vagina. In both cases no radiological investigation was done and serum alpha-fetoprotein was elevated. The histopathological examination of both the tumor masses revealed vaginal endodermal sinus tumor. Periodic-acid-Schiff stain with diastase showed diastase resistant hyaline globules. These findings confirmed the diagnosis of endodermal sinus tumor in both cases. Vaginal endodermal sinus tumor is both locally aggressive and capable of metastasis. The serum alpha-fetoprotein level is a useful marker for diagnosis and monitoring the recurrence of vaginal endodermal sinus tumor in infants. Early detection and therapy is important because of its aggressive nature and good response to chemotherapy.

  7. Imaging the sphenoid sinus: pictorial essay

    International Nuclear Information System (INIS)

    This paper focuses on the spectrum of sphenoid sinus lesions that may be seen radiologically and the mapping of disease extent. Imaging plays a central role in the assessment of sphenoid sinus disease. Although primary sphenoid sinus disease is uncommon, this sinus is nevertheless affected secondarily by a variety of pathological processes. Computer tomography is effective in demonstrating sphenoid lesions in most cases. However, magnetic resonance imaging is the modality of choice as it can identify early soft-tissue thickening, so delineating the lesion in relation to the cavernous sinus and related abnormalities in the sphenoid sinus. Imaging also plays an important part in helping a surgeon plan a biopsy approach. Copyright (1999) Blackwell Science Pty Ltd

  8. Excision and primary closure of pilonidal sinus disease: worthwhile option with an acceptable recurrence rate.

    Gilani, S N S

    2012-01-31

    BACKGROUND: Treatment of pilonidal sinus disease is controversial. Many claim policy of marsupialisation and healing by secondary intention. This is demanding in terms of nursing care and time lost from work. AIMS: To examine outcome of excision and primary closure of chronic pilonidal disease on recurrence rate and patient\\'s daily activities. PATIENTS AND METHODS: One hundred and fourteen consecutive elective patients who had excision and primary closure of pilonidal sinus disease were reviewed. The demographic data and the post-operative outcome were studied. RESULTS: The recurrence of pilonidal sinus was noted in 9% of patients, wound breakdown occasioning delayed healing in 9%, patients able to drive by day 16 on average. The mean time to return to work was 20.5 days; duration of analgesia, 2.4 days; and duration of antibiotic treatment, 4.7 days. CONCLUSION: Excision and primary closure of chronic pilonidal sinus has low recurrence rate with early return to activities. Primary closure appears to be a cost-effective option for uncomplicated pilonidal sinus disease.

    Physicochemical characteristics of a biomaterial directly influence its biological behavior and fate. However, anatomical and physiological particularities of the recipient site also seem to contribute with this process. The present study aimed to evaluate bone healing of maxillary sinus augmentation using a novel bioactive glass ceramic in comparison with a bovine hydroxyapatite. Bilateral sinus augmentation was performed in adult male rabbits, divided into 4 groups according to the biomaterial used: BO-particulate bovine HA Bio-Oss(®) (BO), BO+G-particulate bovine HA + particulate autogenous bone graft (G), BS-particulate glass ceramic (180-212 μm) Biosilicate(®) (BS), and BS+G-particulate glass ceramic + G. After 45 and 90 days, animals were euthanized and the specimens prepared to be analyzed under light and polarized microscopy, immunohistochemistry, scanning electron microscopy (SEM), and micro-computed tomography (μCT). Results revealed different degradation pattern between both biomaterials, despite the association with bone graft. BS caused a more intense chronic inflammation with foreign body reaction, which led to a difficulty in bone formation. Besides this evidence, SEM and μCT confirmed direct contact between newly formed bone and biomaterial, along with osteopontin and osteocalcin immunolabeling. Bone matrix mineralization was late in BS group but became similar to BO at day 90. These results clearly indicate that further studies about Biosilicate(®) are necessary to identify the factors that resulted in an unfavorable healing response when used in maxillary sinus augmentation.

  11. Cancer of the nasal cavity and ethmoid/sphenoid sinuses

    International Nuclear Information System (INIS)

    During the period from October 1964 to September 1975, 32 patients were treated at the University of Florida for a variety of malignant tumors of the nasal cavity and ethmoid/sphenoid sinuses. All were treated with radical irradiation, 6091 to 7972 rad, in 6 to 9 weeks, cobalt-60. Pretreatment work-up revealed evidence of orbital invasion in 7 patients and involvement of the cranial contents, base of skull, or nasopharynx in an additional 15 patients. Local control was achieved in 95% of nasal cavity cases and 71% of ethmoid/sphenoid sinus cases at 2 years or more. The 5-year actuarial survival rate was 59%, and 5-year survival without evidence of disease as 50% (13/26). Patterns of extension in advanced lesions are clues to potential undetected extension in early cases which must be included in the treatment volume. Eye complications were minimal when it was possible to avoid treatment of the entire eye, but developed in all cases requiring treatment of the entire orbit. Acute and chronic complications involving the eye, ear, central nervous system, sinuses, and nose were reviewed and correlated with initial tumor extent, dose, and radiation treatement technique

  12. The Etiology and Pathogenesis of Chronic Rhinosinusitis: a Review of Current Hypotheses.

    Lam, Kent; Schleimer, Robert; Kern, Robert C

    2015-07-01

    Chronic rhinosinusitis (CRS) is a broad clinical syndrome that is characterized by prolonged mucosal inflammation of the nose and paranasal sinuses, and is typically divided into two subtypes based on the presence or absence of nasal polyps. The etiology and pathogenesis of both forms remain areas of active research. Over the last 15 years, a number of hypotheses have been proposed to explain all or part of the clinical CRS spectrum. These hypotheses reflect the concept that CRS results from a dysfunctional interplay between individual host characteristics and factors exogenous to the host. Six broad theories on CRS etiology and pathogenesis are discussed as follows: (1) the "fungal hypothesis," (2) the "superantigen hypothesis," (3) the "biofilm hypothesis," and (4) the "microbiome hypothesis," all of which emphasize key environmental factors, and (5) the "eicosanoid hypothesis" and (6) the "immune barrier hypothesis," which describe specific host factors. These theories are reviewed, and the evidence supporting them is critically appraised. PMID:26143392

    To facilitate safe placement of orthodontic anchor screws (miniscrews), we investigated the frequency of maxillary sinus perforation after screw placement and the effect of sinus perforation on screw stability. Maxillary sinus perforations involving 82 miniscrews (diameter, 1.6 mm; length, 8 mm) were evaluated using cone-beam computed tomography. All miniscrews were placed in maxillary alveolar bone between the second premolar and first molar for anchorage for anterior retraction in patients undergoing first premolar extraction. The placement torque and screw mobility of each implant were determined using a torque tester and a Periotest device, and variability in these values in relation to sinus perforation was evaluated. Eight of the 82 miniscrews perforated the maxillary sinus. There was no case of sinusitis in patients with miniscrew perforation and no significant difference in screw mobility or placement torque between perforating and non-perforating miniscrews. The sinus floor was significantly thinner in perforated cases than in non-perforated cases. A sinus floor thickness of 6.0 mm or more is recommended in order to avoid miniscrew perforation of the maxillary sinus. PMID:26062857

    Catheter ablation for inappropriate sinus tachycardia (IST) is recommended for patients symptomatic for palpitations and refractory to other treatments. The current approach consists in sinus node modification (SNM), achieved by ablation of the cranial part of the sinus node to eliminate faster sinus rates while trying to preserve chronotropic competence. This approach has a limited efficacy, with a very modest long-term clinical success. To overcome this, proper patient selection is crucial and an epicardial approach should always be considered. This brief review will discuss the current role and limitations of catheter ablation in the management of patients with IST. PMID:26310299

  15. Imaging studies of pyriform sinus fistula

    International Nuclear Information System (INIS)

    Pyriform sinus fistula (PSF) refers to a persistent embryologic third or fourth pharyngeal pouch, which typically presents as a congenital sinus tract that originates from the pyriform sinus. The sinus tract is often diagnosed by a barium study or direct endoscopic inspection. Utilization of advanced imaging studies, including ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), may aid in the diagnosis of this disease entity. To review the imaging findings of PSF and demonstrate the value of various cross-sectional imaging (US, CT, and MRI) in the diagnosis of PSF. PSF in five children was verified surgically. Preoperative barium esophagography, US, CT, and MRI were performed selectively in these patients. The clinical and imaging findings are reviewed retrospectively. Barium studies demonstrated the sinus tract in all five patients. US, CT, and MRI demonstrated an associated inflammatory process. By utilizing the trumpet maneuver, the presence of sinus tract was evident in two patients during US. The sinus tract is also demonstrated by CT in another patient. Although barium esophagography is advantageous in demonstration of the sinus tract in PSF, US and CT are also capable of showing the sinus tract. The extent of inflammatory process related to PSF is better delineated by US, CT, and MRI. (orig.)

    2016-07-01

    Most sinus infections are viral and only a small percentage develop bacterial infection. Rhino-, influenza, and para-influenza viruses are the most frequent viral causes of sinusitis. The most common bacterial isolates from children and adult patients with community-acquired acute bacterial sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. Staphylococcus aureus and anaerobic organisms (Prevotella and Porphyromonas, Fusobacterium, and Peptostreptococcus spp.) are the commonest isolates in chronic rhinosinusitis (CRS). Aerobic and anaerobic beta lactamase-producing bacteria (BLPB) were recovered from over a third of these patients. Methicillin-resistant S. aureus (MRSA) accounted for over 60 % of S. aureus isolates. Pseudomonas aeruginosa and other aerobic and facultative Gram-negative rods are frequently recovered in nosocomial sinusitis, the immunocompromised host, individuals with human immunodeficiency virus infection, and in cystic fibrosis. The CRS infection evolves the formation of a biofilm that might play a significant role in the pathogenesis and persistence of CRS. The microbiology of sinusitis is influenced by previous antimicrobial therapy, vaccinations, and the presence of normal flora capable of interfering with the growth of pathogens. Recognition of the unique microbiology of CRS and their antimicrobial susceptibility is of great importance when selecting antimicrobial therapy. PMID:27086363

    The JGI Fungal Genomics Program aims to scale up sequencing and analysis of fungal genomes to explore the diversity of fungi important for energy and the environment, and to promote functional studies on a system level. Combining new sequencing technologies and comparative genomics tools, JGI is now leading the world in fungal genome sequencing and analysis. Over 120 sequenced fungal genomes with analytical tools are available via MycoCosm (www.jgi.doe.gov/fungi), a web-portal for fungal biologists. Our model of interacting with user communities, unique among other sequencing centers, helps organize these communities, improves genome annotation and analysis work, and facilitates new larger-scale genomic projects. This resulted in 20 high-profile papers published in 2011 alone and contributing to the Genomics Encyclopedia of Fungi, which targets fungi related to plant health (symbionts, pathogens, and biocontrol agents) and biorefinery processes (cellulose degradation, sugar fermentation, industrial hosts). Our next grand challenges include larger scale exploration of fungal diversity (1000 fungal genomes), developing molecular tools for DOE-relevant model organisms, and analysis of complex systems and metagenomes.

  5. Endovascular treatment for intracranial venous sinus thrombosis

    International Nuclear Information System (INIS)

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

    Full Text Available Introduction: The pneumocele is a pathological expansion of paranasal sinus containing only air, which can move the nearby structures. Radiologically is a hiperneumatizacion and elongation of paranasal sinus, that can be associated with bone loss. Description: Patient with facial fullness and pains on right side, occasionally nasal blockage that worsen with pressure changes, at exploration presents protrusion of maxillary mucosa into the nostril. Discussion: Pneumoceles can occur in any paranasal sinus. Usually remain asymptomatic and they are not diagnosed until it takes place an external deformity or displacement of neighbouring structures to the sinus, causing symptoms. Conclusion: The maxillary sinus neumoceles are a rare differential diagnosis of mucocele, tumors and trigeminal neuralgia. Surgery is curative, preferring an endoscopic approach.

    2016-01-01

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

    Full Text Available Ectopic tooth eruption into an area other than the oral cavity is rare. Nasal septum, mandibular condyle, coronoid process and infratemporal fossa space have been reported as frequent locations for ectopic tooth eruption. Ectopic teeth located within the maxillary sinus may be asymptomatic, found only in routine examinations. Headache, sinusitis and nasal obstruction are some of the associated symptoms. The differential diagnosis includes foreign bodies (rhinolith, infections (syphilis and tuberculosis, benign lesions (hemangioma, osteoma, calcifi ed polyp and malign lesions (osteosarcoma. Upper third molars located within the maxillary sinus may be associated with the development of mucocele or dentigerous cyst. The aim of this paper was to describe the case of a 24-year old female patient with an ectopic right upper third molar in the maxillary sinus. A hyperdense area was observed with sinus obliteration, consistent with mucous material.

Its key project, the Genomics Encyclopedia of Fungi, targets fungi related to plant health (symbionts, pathogens, and biocontrol agents) and biorefinery processes (cellulose degradation, sugar fermentation, industrial hosts), and explores fungal diversity by means of genome sequencing and analysis. Over 50 fungal genomes have been sequenced by JGI to date and released through MycoCosm (www.jgi.doe.gov/fungi), a fungal web-portal, which integrates sequence and functional data with genome analysis tools for user community. Sequence analysis supported by functional genomics leads to developing parts list for complex systems ranging from ecosystems of biofuel crops to biorefineries. Recent examples of such 'parts' suggested by comparative genomics and functional analysis in these areas are presented here

    Fungal toenail infection (onychomycosis) is characterised as infection of part or all of the toenail unit, which includes the nail plate, the nail bed, and the nail matrix. Over time, the infection causes discoloration and distortion of part or all of the nail unit. Fungal infections are reported to cause 23% of foot diseases and 50% of nail conditions in people seen by dermatologists, but are less common in the general population, affecting 3% to 12% of people.Infection can cause discomfo...

  12. Clinical study on the observation of unilateral shadows in the maxillary sinus

    International Nuclear Information System (INIS)

    In the everyday examination of patients exhibiting a unilateral shadow in the maxillary sinus upon imaging, the differentiation of chronic sinusitis from other diseases, including malignant tumors, is extremely important. A unilateral shadow in the maxillary sinus was detected on scout films and a subsequent CT examination of the sinus was performed in 108 patients who visited our department between January 1994 and December 1998. Bone destruction was suspected after scout films were taken in 2 patients with malignant tumors. These 2 patients account for only a small percentage of the total patient population, but account for as much as 50% of the patients with malignant tumors. In cases of malignant tumors, the CT images suggesting bone destruction agreed with operative findings. CT seems to be a useful tool for evaluating the condition of the bone. When the density of scout films and CT images were compared, no significant difference was detected, suggesting that scout films can be used for the screening of malignant tumors. The density was (+++) in both the scout films and the CT images of the 2 patients with malignant tumors. Finally, we present a flow chart for the diagnosis of unilateral maxillary sinus shadows that has been recently adopted as the basic protocol used in our department. (author)

    Full Text Available Objective : Chronic granulomatous disease (CGD is an inherited disorder of the Nicotinamide adenine dinucleotide phosphate reduced oxidase complex characterized by recurrent bacterial and fungal infections. Disseminated infection by combination of opportunistic agents is being increasingly reported in CGD patients. We presented in the retrospective review of medical records, the etiology, presentation, clinical characteristics the infections detected, predisposing condition and outcome of nocardiosis and actinomycosis involved in a group of pediatric patients diagnosed with CGD. Materials and Methods: The clinical presentation of CGD-related infections was reviewed retrospectively from the medical records of all 12 patients with CGD. We studied respectively 12 patients between 2001 and 2008, and we analyzed two pediatric patients with CGD who acquired Nocardia and Actinomyces infections, and their clinical and microbiological characteristics were described. The material for investigations was collected from scrapings, crusts, pus from subcutaneous abscesses or exudation from sinus tracts, surgical debridement, and biopsy specimens. The microbiological diagnosis was determined by biochemical tests, histology, microscopy, and culture of clinical samples. Results: The medical records of 12 diagnosed CGD patients with suspected nocardiosis or actinomycosis were reviewed. One patient was diagnosed with actinomycosis and one patient with nocardiosis. Patients consisted of seven males and five females with ranging ages of 3 to 18 years. Nocardiosis and actinomycosis isolated in the two patients were confirmed by histology and culture methods. Neutrophil oxidative burst were absent (NBT=0 in both patients. The most common manifestations of CGD due to fungal infections, actinomycosis, and nocardiosis were osteomyelitis (42.8%, pulmonary infections (28.6%, lymphadenopathy (14.3%, and skin involvement (14.3% during their illness. Conclusion: Nocardiosis

    Full Text Available ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01. RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006 between the tooth roots in diseased maxillary sinuses (6.09% and those in normal sinuses (3.43%. The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001. Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.

    2002-08-01

    Full Text Available Maxillary sinus atelectasis is a rare and relatively unknown disease. Most patients present with non-sinonasel complaints. Negative intracavitary pressure due to ostial obstruction is suggested as the most probable etiology. Two patients with sinus atelectasis are presented in this paper: Case 1 presented with enophthalmus and maxillary sinus opacity and atelectasis in imaging. Endoscopic uncinectomy and midle antrostomy was done for this patient. Case 2 presented with mid-facial deformity and depression. Caldwel-Luc procedure with inferior meatal antrostomy was done. In 1 year follow up, they were asymptomatic and with no deterioration of facial deformity.

  16. Postoperative imaging of paranasal sinuses

    International Nuclear Information System (INIS)

    The radiological interpretation of postoperative changes of the paranasal sinuses requires knowledge of why and how the surgical intervention was performed and what the basic clinical findings were. It is important to know whether there was an inflammation, a reconstructive procedure, or a tumorous process. Multidetector computed tomography (MDCT) evaluated in a high-resolution bone window level setting represents the method of choice for imaging after nonfunctional and functional procedures after inflammatory changes as well as for imaging after reconstructive surgery because of facial trauma or before dental implantation. In the postoperative follow-up of tumor patients contrast-enhanced MDCT evaluated in a soft tissue window and bone window and especially magnetic resonance imaging (MRI) represent the standard. In many cases it is possible to differentiate tumor recurrence from inflammation with the help of contrast-enhanced multiplanar MRI and to detect bone marrow changes prior to CT. (orig.)

    International Nuclear Information System (INIS)

    Radiation-induced cancer of the head and neck is well known, but radiation-induced sarcoma is rare. Only nine cases have been reported in the Japanese literature. We treated a patient with post irradiation sarcoma arising in the maxillary sinus. She is now 60 years old and had received radiation therapy for left maxillary carcinoma in 1952. In 1972, left maxillary sarcoma was found and she received postoperative radiation therapy again. Then right nasal carcinoma was found in 1980, and she again received postoperative radiation therapy. Then left maxillary sarcoma was found in 1992. There have been no previous reports of three consecutive radiation-induced malignancies developing in a patient. (author)

  20. Diagnostic value of computerized tomography of nasal sinuses in qualification for functional endoscopic sinus surgery (FESS)

    International Nuclear Information System (INIS)

    Functional endoscopic sinus surgery (FESS) gained indisputable reputation as method of choice in treatment of nose and nasal sinus diseases. The introduction of this method was possible, among others, due to precise radiological diagnostics (CT). Traditional radiological examinations of nasal sinus do not allow for detailed diagnostics and analysis of anatomic anomalies such as: dehiscention in vicinity of carotic artery or ophthalmic nerve which have basic significance while establishing surgical risk. The paper presents 20 cases of nasal sinus CT of patients qualified for functional endoscopic surgery comparative analysis with traditional radiograms were performed. (author)

    Methamphetamines are the second most commonly used illicit drug worldwide and cost the United States health-care system ∼$23.4 billion annually. Use of this drug affects multiple organ systems and causes a variety of clinical manifestations. Although there are commonly known sequelae of methamphetamine abuse such as "meth mouth," there is limited evidence regarding maxillary sinus manifestations. The following cases highlight the initial evaluation and management of two methamphetamine abusers with loculated purulent collections within the maxillary sinus as a result of methamphetamine abuse. Our aim was to delineate the otolaryngologic symptoms associated with the patients' methamphetamine abuse. Computed tomography and magnetic resonance imaging studies revealed loculated purulent collections within the maxillary sinus of probable odontogenic origin in both patients. Methamphetamine abuse leading to rampant caries and poor oral hygiene may predispose individuals for craniofacial infections and fluid collections. These cases illustrate the development of maxillary sinusitis and maxilla mucoceles that have been associated with methamphetamine use. PMID:25675268

    Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

  3. Sympathoinhibition and hypotension in carotid sinus hypersensitivity

    Smith, M. L.; Ellenbogen, K. A.; Eckberg, D. L.

    1992-01-01

    Carotid sinus reflex hypersensitivity is a known cause of syncope in humans. The condition is characterized by cardioinhibition and vasodepression, each to varying degrees. The extent and importance of sympathoinhibition has not been determined in patients with carotid sinus hypersensitivity. This study reports on the extent of sympathoinhibition measured directly directly during carotid massage with and without atrioventricular sequential pacing, in a patient with symptomatic carotid sinus reflex hypersensitivity. Carotid massage elicited asystole, hypotension and complete inhibition of muscle sympathetic nerve activity. Carotid massage during atrioventricular pacing produced similar sympathoinhibition, but with minimal hypotension. Therefore, sympathoinhibition did not contribute importantly to the hypotension during carotid massage in the supine position in this patient. Further investigations are required to elucidate the relation of sympathoinhibition to hypotension in patients with carotid sinus hypersensitivity in the upright position.

  5. Development of maxillary sinuses in childhood

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the development of the maxillary sinuses in childhood. Between June 1983 and December 1985, a total of 120 children under 15 years old were enrolled in this study. Cranial X-ray CT scans were performed using a GE CT/T 8800 and slice thickness were 1.5 mm under 2 years old and 5.0 mm for age above 3 years. Forty-five patients who had facial anomalies, or growth retardation, or premature infants were excluded from further analysis. The remaining 75 patients were evaluated for the development of the maxillary sinuses. The scans were made in the coronal and saggital planes. Anterior-posterior diameter (length) and mid-lateral diameter (width), and volume of the maxillary sinuses were measured by using the image processing system that was developed by us. Cranio-caudal diameter (height) was calculated by multiplying the slice thickness by the total number of the slices taken from the area of the maxillary sinus. Three dimensional structures of the maxillary sinuses were also displayed using the same system. The sizes of maxillary sinuses in the new born were 7.3 ± 1.9 mm(mean ± S.D.) in length, 6.7 ± 1.6 mmin height, and 5.2 ± 1.3 mm in width. These results were similar to those reported by others. The sizes of the maxillary sinuses were increased rapidly by the age 3 - 4 years. The numerical values for theses three measurements were greater than those previously reported, especially for height. The levels of upper borders of these maxillary sinuses in infants and young children were higher than those of inferior rimbs of the orbits. The results for the three dimensional displays and volume measurements performed on 66 children above 1 year old are also presented. (author)

    The study builds on the concept of united airways, which describes the link between the upper and lower airways. Explorations of this concept have mainly related to asthma and less to chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate paranasal sinus opacification at magnetic resonance imaging (MRI) in COPD, self-reported asthma and respiratory symptoms. In this cross-sectional study, 880 randomly selected participants in the Nord-Trøndelag health survey (HUNT) (mean age 57.7 years, range 50-66 years, 463 women) were investigated using MRI of the paranasal sinuses. Participants were allocated to four mutually exclusive groups: (1) COPD (n = 20), (2) asthma (n = 89), (3) respiratory symptoms (n = 199), and (4) reference group (n = 572). Paranasal sinus opacifications were categorised as mucosal thickening, polyps and retention cysts, and fluid. In each participant, measurements ≥1 mm from all sinuses were summed to give a total for each category of opacities. The sums for these three categories were further added together, and referred to as the total sum. Using the 75th percentile cut-off values, the likelihood of having paranasal sinus opacifications was more than six times higher in participants with COPD and twice as high in participants with asthma than among the reference group. Respiratory symptoms were only associated with mucosal thickening. The present study shows that paranasal sinus opacification is associated not only with asthma, but also with COPD and respiratory symptoms. This is in accordance with the united airways hypothesis, and should be kept in mind when handling patients with these conditions. PMID:26499376

  10. Absence of pulmonary aspiration of sinus contents in patients with asthma and sinusitis

    International Nuclear Information System (INIS)

    The frequent association of asthma and paranasal sinusitis has been ascribed to a nasobronchial reflex, aspiration of sinus secretions, or enhanced beta-adrenergic blockade. We investigated possible pulmonary aspiration in a pilot study (eight patients) and follow-up study (13 patients) by means of a radionuclide technique. In the pilot study, the aim was to demonstrate aspiration as well as visibility of the radionuclide in the thorax during a period of 24 hours. The radionuclide was initially placed bronchoscopically in the bronchial tree in four patients and was still clearly visible in the same position after 24 hours in three patients. Aspiration from the nasopharynx was unequivocally demonstrated in two of four patients with depressed consciousness. The follow-up study population consisted of four patients with maxillary sinusitis only and nine patients with sinusitis and asthma. The radionuclide was placed in a maxillary sinus during therapeutic puncture. In the patients with only sinusitis as well as patients with asthma and sinusitis the radionuclide could be demonstrated in the maxillary sinus, nasopharynx, esophagus, and lower gastrointestinal tract during a 24-hour period. However, no pulmonary aspiration of radionuclide could be demonstrated in any patient. We conclude that seeding of the lower airways by mucopurulent secretions is unlikely to account for coexistent pulmonary disease. The association is probably related to generalized mucosal disease affecting both upper and lower airways

    Traumatic injuries in childhood may disrupt root development leading to a tooth with open apex. Apexification procedures in such cases aim at root end closure after reasonable period of time. In some chronic cases, complete healing of the periapical area does not occur resulting in development of a nonhealing sinus. Failure of nonsurgical approach in such cases needs surgical intervention permitting thorough periapical curettage. In the present case, apexification procedure with MTA achieved ...

    International Nuclear Information System (INIS)

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

    2012-08-01

    This review details some of the advances that have been made in the recent decade in the diagnosis, treatment and epidemiology of pulmonary fungal infections. These advances have occurred because of increasing knowledge regarding the fungal genome, better understanding of the structures of the fungal cell wall and cell membrane and the use of molecular epidemiological techniques. The clinical implications of these advances are more rapid diagnosis and more effective and less toxic antifungal agents. For example, the diagnosis of invasive pulmonary aspergillosis, as well as histoplasmosis and blastomycosis, has improved with the use of easily performed antigen detection systems in serum and bronchoalveolar lavage fluid. Treatment of angioinvasive moulds has improved with the introduction of the new azoles, voriconazole and posaconazole that have broad antifungal activity. Amphotericin B is less frequently used, and when used is often given as lipid formulation to decrease toxicity. The newest agents, the echinocandins, are especially safe as they interfere with the metabolism of the fungal cell wall, a structure not shared with humans cells. Epidemiological advances include the description of the emergence of Cryptococcus gattii in North America and the increase in pulmonary mucormycosis and pneumonia due to Fusarium and Scedosporium species in transplant recipients and patients with haematological malignancies. The emergence of azole resistance among Aspergillus species is especially worrisome and is likely related to increased azole use for treatment of patients, but also to agricultural use of azoles as fungicides in certain countries.

A 3-year-old CF patient presented for evaluation with complaints of chronic periocular erythema, conjunctival injection, and irritation for 2 years. He was treated for presumed allergic conjunctivitis with no improvement and continued to have overall worsening of symptoms on the right greater than the left eye in a waxing and waning pattern. On presentation to the Bascom Palmer Eye Institute, he was noted to have telecanthus and prominent erythema in the region of the medial canthus. Orbital imaging disclosed a mucocele in the right ethmoid sinus. The patient underwent functional endoscopic sinus surgery, with successful marsupialization of the ethmoidal mucocele, which was found on culture to be infected with E. coli. Post-operatively with continuous pulmonary care, the patient remains free of allergic conjunctivitis and E. coli colonization of the upper airway. This case highlights the importance of analyzing the adjacent sinus in patients with chronic, relapsing allergic conjunctivitis refractory to medical management, particularly in patients with underlying systemic diseases such as CF.Keywords: allergic conjuncitivitis, Escherichia Coli, cystic fibrosis, mucocele

    This study is to find out the histopathological characteristics of lymph node sinus containing blood. Routine autopsy was carried out in the randomly selected 102 patients(among them,100 patients died of various diseases, and 2 of non-diseased causes),their superficial lymph nodes locating in the bilateral neck, axilla, inguina, thorax and abdomen were sampled. Haematoxylin-eosin staining was performed on 10% formalin-fixed and paraffin-embedded lymph node tissue sections(5μm).The histological characteristics of the lymph node sinuses containing blood were observed under light microscope. Among the 1362 lymph nodes sampled from the 100 autopsies, lymph sinuses containing blood were found in 809 lymph nodes sampled from 91 cases, but couldn't be seen in the lymph nodes sampled from the non-diseased cases. According to histology, five kinds of lymph sinuses containing blood were found:vascular-opening sinus, blood-deficient sinus, erythrophago-sinus, blood-abundant sinus, and vascular-formative sinus. It is concluded that in the state of disease, the phenomenon of blood in the lymph sinus is not uncommon. Blood could possibly enter into lymph sinus through lymphatic-venous communications between the veins and sinuses in the node. Lymph circulation and blood circulation could communicate with each other in the lymph sinus.

    Surgical site infections (SSIs) are the second most common health care associated infection reported to the National Health Safety Network of the centre of disease control and prevention. SSIs by Mycobacterium tuberculosis are uncommon and diagnosis can be missed. Our patient had primary tuberculosis at surgical site without any evidence of tuberculosis at initial investigation. She presented with repeated discharging sinus at the wound of elective lower uterine caesarean section (LUCS). The case was diagnosed by histo-pathological evidence of chronic granulomatous lesion suggestive of tuberculosis from the excised tissue from wound and detection of acid fast bacilli (AFB) from swab by Ziehl Neelsen staining. After proper diagnosis the patient was treated with anti-tubercular drugs regiment for six months as per schedule of national guidelines for management of tuberculosis of Bangladesh Government. Then the patient was cured from unusual long sufferings. PMID:26007279

    Full Text Available The standard treatment in the early stage of maxillary sinus cancer is surgical resection followed by postoperative radiation therapy. However, for locally advanced maxillary sinus cancer, a multimodality treatment approach is strongly recommended to improve the survival rate and quality of life of the patient. We determined the treatment outcomes of induction chemotherapy, concurrent chemoradiation therapy, and surgical resection for locally advanced maxillary sinus cancer. Forty-four patients with locally advanced maxillary sinus cancer, who had been treated between January 1990 and April 2008 at Kangnam St. Mary's Hospital, were retrospectively analyzed. The objective response rates were 70%, 53%, and 57% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and concurrent chemoradiation therapy groups, respectively. The orbital preservation rates were 83%, 100%, and 75% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and surgical resection groups, respectively. In seven of nine patients in whom the orbit could be preserved after induction chemotherapy, the primary tumors were removed completely. However, although the orbits were preserved in three patients who underwent surgical resection as a primary treatment, all three cases were confirmed to be incomplete resections. We found that active induction chemotherapy for locally advanced cancer of the maxillary sinus increased the possibility of complete resection with orbital preservation as well as tumor down-staging.

  2. CT images of unilateral sinus lesions

    International Nuclear Information System (INIS)

    Computed tomographic images of 49 cases of unilateral sinus lesions were examined, and 4 findings were obtained as follows; 1) On the C.T. images of malignant tumors, detection of bone destruction was easy, but its early erosion was difficult. 2) Fungus infections and papilloma of paranasal sinuses demonstrated bone thickness as well as destruction, and this finding would serve as a differential point from malignant diseases. 3) From the C.T. values of soft tissue shadows in the maxillary sinus, it was impossible to differentiate malignant from benign lesions. However, a calcified or non-homogenous soft tissue shadow was seen only in cases of fungus infections and maxillary adenocarcinoma in malignant tumors, and it would be clinically a very important differential point. 4) Many of the unilateral sinus lesions will prove to be indications for surgery, except acute and allergic sinusitis. The paranasal C.T. examinations should be performed if the case does not respond to a conservative therapy over a month, and a case showing bone destruction by the C.T. images would require an exploratory Caldwell-Luc operation.

  3. Complication of nose and paranasal sinus disease

    International Nuclear Information System (INIS)

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

  4. Diagnosis and Treatment of Odontogenic Cutaneous Sinus Tracts in an 11-Year-Old Boy

    Abstract Odontogenic cutaneous sinus tracts (OCSTs) are generally primarily misdiagnosed and inappropriately treated by virtue of their rarity and the absence of dental symptoms. Accurate diagnosis and treatment and the elimination of the source of infection can reduce the incidence of complications and relieve the pain of the patient. In this case report, we present the case of an 11-year-old patient with an apparent abscess but an unobvious draining sinus tract in his left cheek. Intraorally, a glass-ionomer-cement filling on the occlusal surface of the left mandibular first molar (tooth 36) was noted. Radiographic examination revealed a radiopaque mass inside the crown and pulp chamber and an irregular, radiolucent periapical lesion surrounding the distal root apex. He was diagnosed with an OCTS secondary to a periapical abscess of tooth 36. Precise root canal therapy (RCT) and chronic granuloma debridement was performed; 6 months later, the abscess and sinus had healed completely, and the periapical lesion had resolved. Odontogenic cutaneous sinus tracts are uncommon in the clinic. This case report reminds us of the significance of OCSTs and provides some implications for their diagnosis and treatment.

    A case of primary frontal sinus aspergilloma in a 79 year old non-immunocompromised woman, who presented with a right sided pyocele expanding into the orbit, is presented. The low susceptibility of the frontal sinus is probably related to the brachycephalic shape of the human skull which locates this sinus far anterosuperiorly to the nasal cavity. In human frontal sinus aspergillosis nasal symptoms are absent; the clinical manifestation of this rare disease is initiated by complications, espe...

  13. MR imaging of sacrococcygeal pilonidal sinus

    International Nuclear Information System (INIS)

    The purpose of this study is to evaluate the characteristic MR findings of sacrococcygeal pilonidal is simus. Eight MR images of pathologically proven sacrococcygeal pilonidal sinus were retrospectively reviewed [M:F 7:1 ; age range 9-41(median, 17) years]. In all cases, a sacrococcygeal mass was present. Five of the eight patients experienced pain, and in three was discharge. MR findings were evaluated with regard to the location and extent of the lesion, and the presence of sinus or cyst, and the results were compared with the pathologic findings. According to the clinical manifestations, each case was assigned to one of four groups: the first type (n=3) showed dermal thickening with subcutaneous fatty infiltration of the ipsilateral natal cleft while pathologically, a follicular cyst with dermal fibrosis and multiple fatty lobules with fibrous septa were found to be present. In the secone type (n=3), fluid was observed in the sinus tract, while the pathologic findings demonstrated the presence of an abscess in this area. In the third type (n=1), a cystic lesion with air-fluid level was present; pathologically, an abscess was revealed. The fourth type (n=1) showed only a low signal intensity sinus tract on both T1 and T2-weighted images, while the pathologic findings indicated the presence of hairs and follicles within the tract. The MR findings of sacrococcygeal pilonidal sinus depend on the clinical mainfestation and include subcutaneous fatty infiltration, a sinus tract with or without fluid retention, and a cystic lesion with air fluid level. These findings could be helpful for differentiating between this and other sacrococcygeal lesions

    Thrombosis of the sinuses is a distinct cerebrovascular disorder that, unlike arterial stroke, most often affects young adults and children. The symptoms and clinical course are highly variable. During the past decade, increased awareness of the diagnosis, improved neuro-imaging techniques, and more effective treatment have improved the prognosis. More than 80% of all patients now have a good neurologic outcome. This review summarizes recent insights into the pathogenesis of sinus thrombosis, risk factors, and clinical and radiological diagnosis and discusses the current evidence and controversies about the best treatment.

    Inappropriate sinus tachycardia (IST) is a clinical syndrome lacking formal diagnostic criteria. It is generally defined as an elevated resting heart rate (HR; >90-100 bpm) with an exaggerated response to physical or emotional stress and a clearly sinus mechanism. Clinical manifestations are broad from a complete lack of symptoms to incapacitating incessant tachycardia. Now understood to be relatively prevalent, it is observed to have a generally benign prognosis, though symptoms may persist for years. Whether IST is a single discrete entity or a heterogeneous condition with overlap to other syndromes such as postural orthostatic tachycardia syndrome remains a matter of debate. PMID:26310298

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

    1989-05-01

    In a controlled randomized double-blind trial carried out by 47 physicians in private practice with totally 152 patients with sinusitis the therapeutic success of the following homeopathic drug preparations was investigated: Group A: combination of luffa operculata D4, kalium bicromicum D4 and cinnabaris D3. Group B: combination of kalium bicromicum D4 and cinnabaris D3. Group C: luffa operculata D4. Group D: placebo. Criteria for the therapeutic result were headache, blocked nasal breathing, trigeminal tenderness, reddening and swelling of nasal mucosa and postnasal secretion. There was no remarkable difference in the therapeutic success among the investigated homeopathic drug combinations nor between the active drugs and placebo. Averaged over all four groups 81% of the patients with acute sinusitis and 67% of the patients with chronic sinusitis recovered. In the literature comparable therapeutic results are reported for antibiotic therapy, decongestant nose drops and for the drainage of nasal cavities. PMID:2667526

  6. Prevalence of the subclinical sinus disease in HIV positive patients evaluated by the computed tomography versus a control population

    International Nuclear Information System (INIS)

    To determine the prevalence of subclinical sinus disease in patients infected with the human immunodeficiency virus (HIV), cerebral computed tomography scans (CCT) done at the Tourcoing hospital over an 18-month period in 139 HIV-positive patients and 140 control patients without evidence of active sinus disease were reviewed retrospectively. CCTs were evaluated independently by two physicians who were blinded to clinical data. Mucosal thickening and/or a full patients (20/139, 14.4%) than in the controls (8/140, 5.7%) (p=0.016). Mucosal thickening was the most common abnormality in both groups. CD4+cell counts were not correlated with the radiographic abnormalities studies. These radiographic data suggest that subclinical chronic sinusitis independent from the degree of immune deficiency may be more common in HIV-positive than in HIV-negative subjects. (author)

    Using plate counting and ergosterol assay, single and joint effects of acetochlor and methamidophos on the dynamics of soil fungal population and total fungal biomass in the black soil zone of Northeast China were investigated. The results demonstrated that acetochlor at high concentration levels (150 and 250 mg kg-1) had an acute and mostly chronic toxicity on both the soil fungal population and total fungal biomass, but at a low concentration (50 mg kg-1) generally had a stimulating effect that was stronger with total fungal biomass than with the soil fungal population. Methamidophos at a high concentration level (250 mg kg-1) alone and almost all of its combinations with various dosages of acetochlor increased the soil fungal population, whereas at most sampling dates with 250 mg methamidophos kg-1 soil, total fungal biomass increased, but in combination with acetochlor it was decreased in the early period of incubation and then increased 28 days after incubation. Thus, through measuring the number of colony forming unit of the soil fungal population along with the total fungal biomass, a better understanding on effects of agrochemicals on soil fungi could be made.

    We report six cases of transverse-sigmoid dural arteriovenous fistulae (TS DAVF) treated with percutaneous transvenous embolisation through the occluded sinus. All patients had sinus occlusive lesions: an isolated sinus in five cases and a distal occlusion of the affected sinus in one. Leptomeningeal retrograde venous drainage via the vein of Labbe or the sylvian vein was observed in all patients with an isolated sinus. In five patients a microcatheter was easily passed through the occluded sinus. In four of them, a complete angiographic cure was achieved by packing the sinus with coils. However, in one, sinus packing was ineffective and surgical excision of the affected sinus was necessary. The microcatheter could not be passed through the occluded sinus in one case, and direct packing of the isolated sinus was later required. In all cases, complete cure was achieved without complications. This safe, not very invasive and highly effective treatment for TS DAVF with sinus occlusion is thus worth trying when the occluded segment is relatively short. (orig.)

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

    Background Proximity of the dental roots to the sinus floor makes dental disease a probable cause of maxillary sinusitis. The aim of this study was to find out if maxillary sinus pathologic changes were more prevalent in patients with dental disease and to evaluate the performance of computed tomography (CT) in analyzing and detecting apical periodontitis and other odontogenic causes on the maxillary sinusitis etiology in a Portuguese Caucasian population. Material and Methods Retrospective cohort study. The total sample of 504 patients and their CT was included in this study. The patients were from a private dental clinic, specializing in oral surgery, where the first complaint was not directly related to sinus disease, but with dental pathology. For each patient, the etiological factors of maxillary sinusitis and the imaging CT findings were analyzed. All the axial, coronal and sagittal CT slices were evaluated and general data were registered. The latter was selected based on the maxillary sinus CT published literature. Results 32.40% of patients presented normal sinus (without any etiological factor associated), 29.00% showed presence of etiological and imaging findings in the maxillary sinus, 20.60% had only imaging changes in the maxillary sinus and 18.00% of patients presented only etiological factors and no change in the maxillary sinus. Conclusions Radiological imaging is an important tool for establishing the diagnosis of maxillary sinus pathology. These results indicate that the CT scan should be an excellent tool for complement the odontogenic sinusitis diagnosis.

    2016-01-01

    Nasal polyps are semi-translucent mucosal outgrowths of the paranasal sinuses which typically arise in the setting of chronic rhinosinusitis (CRS). Nasal polyps are also associated with asthma, aspirin sensitivity, cystic fibrosis and allergic fungal rhinosinusitis (AFS). The majority of nasal polyps are bilateral and characterized by tissue edema and eosinophil infiltration. Patients with nasal polyps often present with complaints including nasal obstruction, congestion, rhinorrhea or altered sense of smell. The differential diagnosis ranges from benign masses such as schneiderian papilloma, antrochoanal polyp, angiofibroma and encephalocele to malignant neoplasms such as squamous cell carcinoma (SCC), esthesioneuroblastoma, nasal lymphoma and rhabdomyosarcoma. These lesions may have a similar appearance as nasal polyps and particular attention to an alternative diagnosis for nasal polyps should be entertained if the mass is unilateral or congenital in nature. Workup for patients with a unilateral mass should include radiographic imaging, possible biopsy and careful follow-up when appropriate. Here, we review the disease etiology of nasal polyps and describe the approach to the patient with nasal polyps with emphasis on differential diagnosis and workup. PMID:27466841

  14. Sinus valsalva aneurysm on cardiac CT angiography: assessment and detection

    International Nuclear Information System (INIS)

    After the advent of ECG gated cardiac CT angiography (CCTA) there has been significant improvement in image quality of the ascending aorta. As a result the sinuses of valsalva are readily assessable. Sinuses of valsalva aneurysm can cause significant dysfunction of the aortic root and annulus and can be congenital or acquired. The aneurysm most commonly originates from the right coronary sinus. Complications related to sinuses of valsalva aneurysm can cause chest pain and can be life threatening. The cardiac imager should actively assess the sinuses of valsalva in every CCTA study.

  15. Intraspinal Abscess Associated with Congenital Dermal Sinus: Case Report

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    The author have observed mucoid retention cyst in the right maxillary sinus of the patient, 41 year old woman, complained discharging of purulent exudate on the right maxillary molar area, and obtained the following conclusions; 1. The mucoid retention cyst in maxillary sinus casts a faint dome shaped shadow into the radiolucent image of maxillary sinus. 2. The mucoid retention cyst in maxillary sinus may occurred without the history of trauma. 3. Intraoral standard films are also valuable for the interpretation of the lesions in maxillary sinus but only extraoral roentgenograms.

    We evaluated histologically and tomographically the effects of fresh frozen bone allograft (FFB) or bovine bone mineral (BBM) in maxillary sinus floor augmentations. In total, 30 maxillary sinuses from 30 patients (mean age = 51.17 ± 10.86 years) underwent sinus augmentation. Patients were divided in two test groups (15 sinuses each). The first group was grafted with allograft bone, and the second group received bovine bone mineral. After 6 months, bone samples from each group were collected for histological examination. Implant survival rates were 97.78% (FFB group) and 100% (BBM group) 6 months after functional loading. Median volumetric reductions of 31.2% (11.33-40.56) and 12.22% (9.91-20.59) were observed in the FFB and BBM groups, respectively. Comparisons between the groups for differences in initial and final volumes of bone (p = 0.015) and the rate of resorption (p = 0.009) showed statistically significant differences. The FFB group showed osteoblastic cells in close contact with osteoid matrix, connected through bridges between allograft bone particles and new bone formation. The BBM group showed BBM particles in close contact with new bone, with visible osteoid matrix bridges and osteoblastic cells surrounding it. None showed signs of acute or chronic inflammatory infiltrate. Despite better results with BBM, both FFB and BBM in maxillary sinus augmentation resulted in high percentages of new bone formation, and allowed implant placement with a low rate of failure of osseointegration at a 6-month follow-up.

    Elucidation of pathogenicity mechanisms of the most important human pathogenic fungi, Aspergillus fumigatus and Candida albicans, has gained great interest in the light of the steadily increasing number of cases of invasive fungal infections. A key feature of these infections is the interaction of the different fungal morphotypes with epithelial and immune effector cells in the human host. Because of the high level of complexity, it is necessary to describe and understand invasive fungal i...

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

  20. Radiologic study of the maxillary sinusitis

    International Nuclear Information System (INIS)

    Radiographic features of maxillary sinusitis, type of mucosal thickening, types of bony wall change, and relationship between the radiographic features and symptoms of patients were observed and classified in the Waters' view of 360 patients with 441 maxillary sinuses demonstrating radiologic change was observed in the 154 periapical films. Finally, the value of orthopantomography in the diagnosis of maxillary sinusitis was evaluated in the 138 cases, The obtained results were as followings. 1. Among 441 maxillary sinuses examine by Waters' projection, mucosal thickening was seen in 56.7% and generalized opacification was seen in 36.3%. 2. Among 270 mucosal thickenings classified 8 types, overall regularly thickened type cortical plates was the highest in incidence (36.3%). 3. Bony wall change was seen in 35.6% of all cases and the indistinct while line of the cortical plates was the highest in incidence (78.2%) among the 6 types. 4. Pain (419%) and pus discharge (21.0%) were the most frequent symptoms. And pus discharge, foul odor, and headache was more prevalent in type of generalized opacification than any other types. 5. Regular pneumatization involving all roots of premolars and molars was the highest in incidence (55.0%). The first molar presented the most frequent involvement (61.0%). 6. In orthopantomography, 46.4% showed apparent increased radiopacity and 23.9% showed suspicious increased radiopacity in comparison to Water's projection.

    Full Text Available Traumatic injuries in childhood may disrupt root development leading to a tooth with open apex. Apexification procedures in such cases aim at root end closure after reasonable period of time. In some chronic cases, complete healing of the periapical area does not occur resulting in development of a nonhealing sinus. Failure of nonsurgical approach in such cases needs surgical intervention permitting thorough periapical curettage. In the present case, apexification procedure with MTA achieved root end closure but failed to heal the sinus for which surgical treatment was completed with thorough periapical curettage and application of platelet rich fibrin (PRF and a combination of β-tricalcium phosphate and hydroxyapatite resulted in healing.

  3. Radiological findings in paranasal sinus mucoceles

    International Nuclear Information System (INIS)

    To evaluate the utility of computed tomography (CT) as the technique of choice in the diagnosis and study of the extension of paranasal sinus mucoceles and to assess the role of magnetic resonance (MR) imaging. We carried out a retrospective study of 57 paranasal sinus mucoceles in 56 patients who had been diagnosed and treated from 1977 to 1997. Forth-eight patients had been examined by CT and, of these, six had also undergone MR imaging. Eight patients had only plain X-rays. Most of the mucoceles (73,2%) were located in frontal or frontal-ethmoidal sinus, followed by maxillary sinus (21.5%), the sphenoid sinus was the least frequent sites (5.3%). Of the 49 mucoceles (bilateral in one case) diagnosed by CT, 27 (56.25%) presented expansion and bone destruction, 16 (33,3%) showed only expansion and 6(12%) showed no clear evidence of expansion. Thirty extended to the orbit, four to the endocranium, two to the soft tissues of the forehead and one to the pterygomaxillary fissure and the sphenoidal ridge in one, involvement of both orbits in two and pyomucocele in another. The CT findings were characteristic in nearly every case: well-defined mass, low attenuation (high attenuation when the secretions were very thick), expansive and unenhanced by contrast agents. CT is the technique of choice for the diagnosis of mucocele and to assess their extension and the degree of bone involvement. The utilization of MR imaging facilities the definition of the interface between intracranial and intraorbital structures. (Author) 25 refs

  4. Midface swelling reveals nasofrontal dermal sinus

    International Nuclear Information System (INIS)

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

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

    The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or

    2016-01-01

    Introduction Silent sinus syndrome (SSS) is a rare disorder with protean manifestations. An absence of familiarity with ambiguous and atypical presentations may complicate diagnosis and delay management. Case presentation A 28 year old female patient presented with a chronic history of headache, post-nasal discharge and recurrent facial pain refractory to analgesics. Enophthalmos and hypoglobus progressed over a period of 2 months, and a diagnosis of SSS was confirmed via imaging. Definitive treatment was withheld given the patient’s postpartum state and improvement of symptoms. Discussion SSS typically manifests with painless and progressive, unilateral, enophthalmos and hypoglobus. Since presentation is dominated by ophthalmologic complaints, the ordinary route by which SSS is diagnosed is through ophthalmology review. The predominant complaint in our patient was chronic headaches with facial pain, and mild enophthalmos and hypoglobus were only noted 2 months later at follow-up. This represents an atypical presentation of SSS, and exemplifies the subtle and often ambiguous presenting features of this disorder. Conclusion The protean manifestations of SSS mean that patients may initially present to specialities other than ophthalmology. To ensure rapid diagnosis and appropriate management, it is important that clinicians, particularly in ophthalmology, maxillofacial surgery, and ears, nose and throat (ENT), are familiar with this obscure condition.

  10. Measurement of maxillary sinus volume using Computed Tomography

    International Nuclear Information System (INIS)

    To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm3, respectively. There was a significant sex difference in the sinus volume (p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p<0.0001). In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

    Background: We report the recovery of ophthalmoplegia in 11 patients with cavernous sinus dural arteriovenous fistula (CSDAVF) after sinus packing at follow-up. Methods: Of 18 patients with CSDAVF treated with transvenous cavernous sinus packing between August 2002 and December 2007 at Beijing Tiantan Hospital, there were 9 patients with initial CNIII or CNVI dysfunction and 2 patients with CNVI dysfunction immediately after cavernous sinus packing selected and reevaluated. Results: Of 11 patients with CNIII or CNVI palsy, recovery was complete in 10. In 1 patient, complete CNVI palsy was unchanged because the CSDAVF was not cured. There were 6 men and 5 women with a mean age of 52.9 years. In 5 patients, CNVI palsy was associated with chemosis, proptosis and pulsatile tinnitus. Timing of treatment after onset of symptoms was from 4 to 35 days in 9 patients. All CSDAVFs were Barrow type D. Mean follow-up after treatment was 17.7 months (range, 2-54 months). Conclusion: CSDAVF-induced CNIII or CNVI palsies can be cured after cavernous sinus packing transvenously in most patients.

    Data regarding the prevalence of fungal infections in Vietnam are limited yet they are likely to occur more frequently as increasingly sophisticated healthcare creates more iatrogenic risk factors. In this study, we sought to estimate baseline incidence and prevalence of selected serious fungal infections for the year 2012. We made estimates with a previously described actuarial method, using reports on the incidence and prevalence of various established risk factors for fungal infections from Vietnam, or similar environments, supplemented by personal communications. Global data were used if local data were unavailable. We estimated 2,352,748 episodes of serious fungal infection occurred in Vietnam in 2012. Frequent conditions included recurrent vaginal candidiasis (3893/100,000 women annually), tinea capitis (457/100,000 annually) and chronic pulmonary aspergillosis (61/100,000/5 year period). We estimated 140 cases of cryptococcal meningitis, 206 of penicilliosis and 608 of Pneumocystis jirovecii pneumonia. This is the first summary of Vietnamese fungal infections. The majority of severe disease is due to Aspergillus species, driven by the high prevalence of pulmonary tuberculosis. The AIDS epidemic highlights opportunistic infections, such as penicilliosis and cryptococcosis, which may complicate immunosuppressive treatments. These estimates provide a useful indication of disease prevalence to inform future research and resource allocation but should be verified by further epidemiological approaches. PMID:26449514

    Full Text Available Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococcus aureus growth and the child improved with intravenous cloxacillin therapy. This case is presented due to the rarity of its presentation in this age group and for awareness to consider this entity in children having fever and peri-orbital swelling.

  15. Cavernous sinus extension of pituitary tumors

    International Nuclear Information System (INIS)

    This paper investigates the capability of ultrafast dynamic MR imaging to delineate cavernous sinus extension of pituitary region tumors. The dynamic imaging technique captures a temporal phase when Gd-DTPA-laden blood is in the vascular spaces, but the tumors have not yet enhanced and they appear as filling defects. This phase lasts less than 10 seconds. This information was helpful in the interpretation of seven equivocal cases (five positive, two negative), four of which were confirmed surgically. Dynamic imaging did not add to the determination of the pre- and postcontrast T1SE images in the remaining 15 patients. Dynamic imaging can be useful for delineating cavernous sinus extension of pituitary and perisellar tumors in cases in which the pre- and postgadolinium T1SE images are equivocal

  16. Fungal keratitis: A review

    International Nuclear Information System (INIS)

    Keratomycosis is a vision-threatening fungal corneal infection. The dramatic increase in the number of cases over the past three decades is attributable not only to better diagnostic recognition, improved laboratory techniques and greater awareness by the ophthalmic society as a whole, but is also due to a true increase in the incidence of keratitis related to the indiscriminate use of topical broad-spectrum antibiotics, corticosteroids and immunosuppressive drugs, as well as surgical trauma. Corneal trauma has remained the main predisposing factor over the years, though in recent years HIV-positive cases and AIDS are taking lead in certain areas. Aspergillus, Fusarium and Candida species remains the commonest 'organisms' isolated worldwide. Although the approach to this form of keratitis is similar to other types of microbial keratitis, it remains the most difficult in terms of diagnosis and management. Early recognition, prevention, prompt treatment and timely keratoplasty are crucial for a better outcome. (author)

    Conclusion: Sinus restoration is preferable in patients with severe cerebral venous congestion due to multiple sinus occlusions and/or a restricted collateral venous outlet. CT venography is useful for precise evaluation of the length and configuration of the occluded segment, which thus make it possible to evaluate the feasibility of stenting.

The policies of treatment-surgery, irradiation, or combined treatment-at the University of Texas M.D. Anderson Hospital are discussed for each site. The techniques of treatment are described and the results detailed

  1. Clinical and diagnostic pathways in pediatric fungal infections

    Directory of Open Access Journals (Sweden)

    Elio Castagnola

    2013-07-01

    Full Text Available Generally speaking, in pediatrics the patients mostly affected by fungal infections are hematological patients, followed by those with solid tumors, and transplant recipients. Candida infections generally occur just after birth, whereas Aspergillus infections are age-related, and increase their incidence with age. However, among infections, the incidence of bacteremias are still greater than that of mycoses. In pediatrics, in Italy the immunocompromised patients – thus particularly susceptible to fungal infections – are mainly those with severe combined immunodeficiency, chronic mucocutaneous candidiasis, and chronic granulomatous disease. Particular Aspergillus or Scedosporium infections should be considered in peculiar kinds of patients, such as those affected by cystic fibrosis. Finally, different kinds of fungi should be considered in those who come from or spend a lot time in specific areas, such as South America (e.g. coccidioidomycoses, for which differential diagnosis is with tuberculosis.http://dx.doi.org/10.7175/rhc.v4i1S.859

  2. Prognostic factors of maxillary sinus epithelial carcinoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the relation between clinicopathological character- isties and prognosis in maxillary sinus epithelial carcinoma (ECMS). Methods: 124 such patients were reviewed retrospectively. There were treated by radiotherapy alone (RT-, 40 patients), surgery alone(S-, 18 patients)and combined modality therapy (R+ S-, 66 patients). Kaplan-Meier method was used to analyze the survival, Logrank test was used to compared the difference between groups. Multivariate analysis was performed by Cox proportional hazard model. Results: The overall 5-year survival, cancer-specific survival and progression-free survival rates were 32.5%, 37.4% and 27.2%, respectively. Univariate analysis showed that tumor location, histological type, T stage, N stage, clinical stage and treatment modality were associated with cancer-specific survival and progression-free sur- vival, while age was only associated with cancer-specific survival. Multivariate analysis indicated that histological type, T stage, clinical stage and treatment modality were independent prognostic factors. Conclusions: T stage and clinical stage are the independent prognostic factors for maxillary sinus epithelial carcinoma. Prophylactic neck irradiation is necessary even for T3-T4N0 patients. The best treatment strategy for maxillary sinus carcinoma needs further research. (authors)

    2011-01-01

    Frontal sinus fractures make up about 2-15% of all facial fractures.This is relatively low frequency of occurrence, but it has a large potential of complication and may involve not only the frontal sinuse but more importantly the brain and the eyes. The management depends of the complexity. If anterior wall is fractured with grossly involved nasofrontal duct (NFD) in the injury it is paramount to occlude NFD. Very often, sinus obliteration is done at the same time. In our expirience autogenous cancellous bone graft is considered to be the best grafting material. It has the less short - or long-term complications and the donor site morbidity is insignificant. PMID:21950235

    Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was ...

    In the literature, clinical descriptions of sigmoid sinus thrombosis occurring after closed head injury in children are rare. One to 5 days after trauma to the back of the head, five children (aged 1 to 7 yr) presented with gait ataxia, vomiting, and headache. Trauma was mild in four children. Computed tomography of all the children, performed within 5 days after the injury, showed focal hyperdensity in the region of the left sigmoid sinus. Four children had extra-axial hyperdense collections along the left transverse sinus, and three had skull fractures adjacent to the left sigmoid sinus. Magnetic resonance imaging (MRI) of all the children, performed 2 to 6 days after injury, showed left sigmoid-sinus thrombosis and decreased flow or thrombosis within the lateral third of the left transverse sinus. All the children had MRI scans 4 to 6 weeks after their diagnosis and were followed up for 1 to 12 months. In four children whose symptoms subsided completely within 2 to 10 weeks, MRI showed recanalization of the sigmoid sinus within 4 to 6 weeks after injury. In one child whose symptoms resolved after 6 months, sigmoid-sinus thrombosis persisted with the formation of collateral flow. We conclude that traumatic sigmoid-sinus thrombosis should be suspected when a child has persistent or delayed gait ataxia and vomiting after injury to the back of the head. Computed tomography characteristically demonstrated focal hyperdensity within the sigmoid sinus that we term the dense sigmoid-sinus sign. Because the sinus recanalized and the symptoms subsided in most children within 6 weeks, we conclude that prophylactic medical or surgical intervention is not indicated. PMID:8474644

    The aim of this study was to investigate the relationship between the morphological characteristics of the sphenoid sinus and endoscopic localization of the cavernous sinus (CS) using an extended endoscopic endonasal transsphenoidal approach. Thirty sides of CS in 15 adult cadaver heads were dissected to simulate the extended endoscopic endonasal transsphenoidal approach, and the morphology of the sphenoid sinus and anatomic structures of CS were observed. The opticocarotid recess (OCR), ophthalmomaxillary recess (V1V2R), and maxillomandibular recess (V2V3R) in the lateral wall of the sphenoid sinus were presented in 16 sides (53.3%), 6 sides (20%), and 4 sides (13.3%) of the 30 sides, respectively. OCR is a constant anatomic landmark in endoscopy and coincides with the anterior portion of the clinoidal triangle. The C-shaped internal carotid artery (ICA) in the lateral wall of the sphenoid sinus was presented in 11 sides (36.7%), the upper one-third of which corresponds to the middle portion of the clinoidal triangle, and the lower two-thirds of which correlates to the supratrochlear triangle, infratrochlear triangle, and ophthalmic nerve in CS, around which the medial, lateral, and anteroinferior interspaces are distributed. From a front-to-behind perspective, the C-shaped ICA consists of inferior horizontal segment, anterior vertical segment, clinoidal segment as well as partial subarachnoid segment of the ICA. OCR and C-shaped ICA in the lateral wall of the sphenoid sinus are the 2 reliable anatomic landmarks in the intraoperative location of the parasellar region of CS. PMID:26221856

    Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

    Trichomonal disease typically involves the genital and occasionally respiratory tracts. Although exposure of the upper respiratory tract to infected genital secretions is not uncommon with contemporary sexual practices, trichomonal sinus disease has been rarely described. The present report describes the case of a healthy 17-year-old male admitted to an intensive care unit following multiple trauma, who developed purulent sinusitis on the 4th day of hospitalization. Numerous trichomonads were noted on microscopic examination of sinus aspirate. Further investigation revealed orofacial sexual exposure of the patient to a partner with trichomoniasis. The patient's sinusitis resolved following a course of parenteral metronidazole-containing antibiotics. PMID:19204647

    International Nuclear Information System (INIS)

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

    Pneumatization of the maxillary sinus limits the quantity of alveolar bone available for implant placement and may result in a lack of primary stability and difficulty in achieving osseointegration. The purpose of this study was to retrospectively analyze a group of patients who had implants placed in the posterior maxilla, calculate the prevalence of sinus augmentation, and identify factors related to sinus augmentation. With institutional review board approval, dental records from a population of patients who had implants placed in the maxillary posterior region between January 2000 and December 2004 were used to create a database. Independent variables were classified as continuous (age of the patient at stage 1 implant surgery [S1], time between extraction and S1, time between extraction and sinus augmentation, and time between sinus augmentation and S1) and categorical (gender, implant failure, American Society of Anesthesiologists system classification, smoking, osteoporosis, residual crestal bone height, implant position, implant proximity, prostheses type, and implant diameter and length). The dependent variable was the incidence of a sinus augmentation procedure. Simple logistic regression was used to assess the influence of each factor on the presence of sinus augmentation (P rate of 93.2% over a mean follow-up period of 35.7 months. Of 502 implants, 272 (54.2%) were associated with a sinus augmentation procedure. Among variables, residual crestal bone height (P edentulism. Sinus augmentation was significantly associated with implant failure and wide implants. PMID:21651386

  1. Pathologic changes in the maxillary sinus wall after conservative therapy in odontogenic maxillary sinusitis. Examination using bone scintigraphy

    International Nuclear Information System (INIS)

    Single photon emission computed tomographic bone scintigraphy (bone SPECT) was performed in 16 patients with odontogenic maxillary sinusitis to compare inflammatory changes in the maxillary sinus wall including the alveolar process (bony lesions) before and after conservative therapy. Morphologic changes in bony lesions as evaluated by bone SPECT images correlated with those of the maxillary sinus mucosa (mucosal lesions) as evaluated by CT images. Morphologic changes in the bony lesions also correlated with changes in inflammatory activity in the maxillary alveolar process as functionally evaluated by bone SPECT before and after conservative therapy. Odontogenic maxillary sinusitis is considered a disease in which maxillary alveolitis causes mucosal lesions as well as bony lesions. Changes in alveolitis are associated with morphologic changes in bony lesions after conservative therapy, and these changes affect the pathophysiologic nature of odontogenic maxillary sinusitis. Bone SPECT is valuable for predicting outcome and treatment planning in patients with odontogenic maxillary sinusitis. (author)

  2. Fungal quorum sensing molecules: Role in fungal morphogenesis and pathogenicity.

    2016-05-01

    When microorganisms live together in high numbers, they need to communicate with each other. To achieve cell-cell communication, microorganisms secrete molecules called quorum-sensing molecules (QSMs) that control their biological activities and behaviors. Fungi secrete QSMs such as farnesol, tyrosol, phenylethanol, and tryptophol. The role of QSMs in fungi has been widely studied in both yeasts and filamentous fungi, for example in Candida albicans, C. dubliniensis, Aspergillus niger, A. nidulans, and Fusarium graminearum. QSMs impact fungal morphogenesis (yeast-to-hypha formation) and also play a role in the germination of macroconidia. QSMs cause fungal cells to initiate programmed cell death, or apoptosis, and play a role in fungal pathogenicity. Several types of QSMs are produced during stages of biofilm development to control cell population or morphology in biofilm communities. This review article emphasizes the role of fungal QSMs, especially in fungal morphogenesis, biofilm formation, and pathogenicity. Information about QSMs may lead to improved measures for controlling fungal infection. PMID:26972663

    Serious fungal infections (SFIs) could be more frequent than are recognised. Estimates of the incidence and prevalence of SFIs are essential in order to identify public health problems. We estimated the rates of SFIs in Mexico, following a methodology similar to that used in prior studies. We obtained information about the general population and populations at risk. A systematic literature search was undertaken to identify epidemiological reports of SFIs in Mexico. When Mexican reports were unavailable, we based our estimates on international literature. The most prevalent SFIs in Mexico are recurrent vulvovaginal candidiasis (5999 per 100,000) followed by allergic bronchopulmonary aspergillosis (60 per 100,000), chronic pulmonary aspergillosis (15.9 per 100,000), fungal keratitis (10.4 per 100,000), invasive candidiasis (8.6 per 100,000) and SFIs in HIV (8.2 per 100,000); coccidioidomycosis (7.6 per 100,000), IA (4.56 per 100,000). These correspond to 2,749,159 people affected in any year (2.45% of the population), probably >10,000 deaths and 7000 blind eyes. SFIs affect immunocompromised and healthy populations. Most are associated with high morbidity and mortality rates. Validation of these estimates with epidemiological studies is required. The burdens indicate that an urgent need to improve medical skills, surveillance, diagnosis, and management of SFIs exists. PMID:26449505

  6. Anaerobic fungal populations

    International Nuclear Information System (INIS)

    The development of molecular techniques has greatly broadened our view of microbial diversity and enabled a more complete detection and description of microbial communities. The application of these techniques provides a simple means of following community changes, for example, Ishii et al. described transient and more stable inhabitants in another dynamic microbial system, compost. Our present knowledge of anaerobic gut fungal population diversity within the gastrointestinal tract is based upon isolation, cultivation and observations in vivo. It is likely that there are many species yet to be described, some of which may be non-culturable. We have observed a distinct difference in the ease of cultivation between the different genera, for example, Caecomyes isolates are especially difficult to isolate and maintain in vitro, a feature that is likely to result in the under representation of this genera in culture-based enumerations. The anaerobic gut fungi are the only known obligately anaerobic fungi. For the majority of their life cycles, they are found tightly associated with solid digesta in the rumen and/or hindgut. They produce potent fibrolytic enzymes and grow invasively on and into the plant material they are digesting making them important contributors to fibre digestion. This close association with intestinal digesta has made it difficult to accurately determine the amount of fungal biomass present in the rumen, with Orpin suggesting 8% contribution to the total microbial biomass, whereas Rezaeian et al. more recently gave a value of approximately 20%. It is clear that the rumen microbial complement is affected by dietary changes, and that the fungi are more important in digestion in the rumens of animals fed with high-fibre diets. It seems likely that the gut fungi play an important role within the rumen as primary colonizers of plant fibre, and so we are particularly interested in being able to measure the appearance and diversity of fungi on the plant

  7. Fungal Biotransformation of Tetracycline Antibiotics.

    2016-08-01

    The commercial antibiotics tetracycline (3), minocycline (4), chlortetracycline (5), oxytetracycline (6), and doxycycline (7) were biotransformed by a marine-derived fungus Paecilomyces sp. to yield seco-cyclines A-H (9-14, 18 and 19) and hemi-cyclines A-E (20-24). Structures were assigned by detailed spectroscopic analysis, and in the case of 10 X-ray crystallography. Parallel mechanisms account for substrate-product specificity, where 3-5 yield seco-cyclines and 6 and 7 yield hemi-cyclines. The susceptibility of 3-7 to fungal biotransformation is indicative of an unexpected potential for tetracycline "degradation" (i.e., antibiotic resistance) in fungal genomes. Significantly, the fungal-derived tetracycline-like viridicatumtoxins are resistant to fungal biotransformation, providing chemical insights that could inform the development of new tetracycline antibiotics resistant to enzymatic degradation.

    Background Ergosterol has been considered the “fungal sterol” for almost 125 years; however, additional sterol data superimposed on a recent molecular phylogeny of kingdom Fungi reveals a different and more complex situation. Methodology/Principal Findings The interpretation of sterol distribution data in a modern phylogenetic context indicates that there is a clear trend from cholesterol and other Δ5 sterols in the earliest diverging fungal species to ergosterol in later diverging fungi.

  11. Chronic complicated osteomyelitis

    International Nuclear Information System (INIS)

    Fourteen patients with prior trauma and/or surgery of the lower extremity and suspected active chronic osteomyelitis underwent MR imaging. Eleven patients also underwent In-111 scanning. All patients had surgical confirmation, MR imaging could assess the extent of abnormal marrow and distinguish abnormal marrow due to granulation tissue from active osteomyelitis. The presence and extent of soft-tissue infection could be determined and distinguished from bone involvement in spite of tissue distortion. The course and origin of sinus tracts could be followed. MR imaging was more sensitive to active infection than In-111 scanning. All 11 cases of active osteomyelitis were correctly diagnosed with MR imaging. In-111 scans were positive in only five of the eight cases of active infection in which scans were obtained. MR imaging is useful in chronic complicated osteomyelitis

  12. A study of the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume

    International Nuclear Information System (INIS)

    In an attempt to study the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume, sinus volumes were measured by coronal CT scans of the paranasal sinus. Two hundred and four maxillary sinuses of 102 patients, the frontal sinuses of 62 patients and the sphenoid sinuses of 68 patients with no inflammatory changes detectable on CT scans of the each paranasal sinus and nasal cavity were analyzed. The volumes of the maxillary sinus showed a normal distribution, and its mean volume and standard deviation were 20.5±9.2 cm3. The logarithms of both frontal and sphenoid sinus volumes exhibited an normal distribution. The mean volume of the frontal sinus and the sphenoid sinus, which were calculated using logarithms of the sinus volumes statistically, were 8.3 cm3 and 9.6 cm3 respectively. The correlation coefficient was 0.134 between the maxillary and frontal sinus, 0.445 between the maxillary and sphenoid sinus and 0.315 between the frontal and sphenoid sinus. It is suggested that differences in the volume distribution pattern between the maxillary sinus and frontal or sphenoid sinus might be caused by differences in the growing process of each sinus.

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

    Full Text Available Of the ceramide monohexosides (CMHs, gluco- and galactosylceramides are the main neutral glycosphingolipids expressed in fungal cells. Their structural determination is greatly dependent on the use of mass spectrometric techniques, including fast atom bombardment-mass spectrometry (FAB-MS, electrospray ionization (ESI-MS, and energy collision-induced dissociation mass spectrometry (ESI-MS/CID-MS. Nuclear magnetic resonance (NMR has also been used successfully. Such a combination of techniques, combined with classical analytical separation, such as HPTLC and column chromatography, has led to the structural elucidation of a great number of fungal CMHs. The structure of fungal CMH is conserved among fungal species and consists of a glucose or galactose residue attached to a ceramide moiety containing 9-methyl-4,8-sphingadienine with an amidic linkage to hydroxylated fatty acids, most commonly having 16 or 18 carbon atoms and unsaturation between C-3 and C-4. Along with their unique structural characteristics, fungal CMHs have a peculiar subcellular distribution and striking biological properties. Fungal cerebrosides were also characterized as antigenic molecules directly or indirectly involved in cell growth or differentiation in Schizophyllum commune, Cryptococcus neoformans, Pseudallescheria boydii, Candida albicans, Aspergillus nidulans, A.fumigatus and Colletotrichum gloeosporioides. Besides classical techniques for cerebroside (CMH analysis, we now describe new approaches, combining conventional TLC and mass spectrometry, as well as emerging technologies for subcellular localization and distribution of glycosphingolipids by SIMS and imaging MALDI TOF .

    2016-05-01

    Odontogenic cutaneous sinus tracts (OCSTs) are generally primarily misdiagnosed and inappropriately treated by virtue of their rarity and the absence of dental symptoms. Accurate diagnosis and treatment and the elimination of the source of infection can reduce the incidence of complications and relieve the pain of the patient.In this case report, we present the case of an 11-year-old patient with an apparent abscess but an unobvious draining sinus tract in his left cheek. Intraorally, a glass-ionomer-cement filling on the occlusal surface of the left mandibular first molar (tooth 36) was noted. Radiographic examination revealed a radiopaque mass inside the crown and pulp chamber and an irregular, radiolucent periapical lesion surrounding the distal root apex. He was diagnosed with an OCTS secondary to a periapical abscess of tooth 36. Precise root canal therapy (RCT) and chronic granuloma debridement was performed; 6 months later, the abscess and sinus had healed completely, and the periapical lesion had resolved.Odontogenic cutaneous sinus tracts are uncommon in the clinic. This case report reminds us of the significance of OCSTs and provides some implications for their diagnosis and treatment. PMID:27196471

  17. A RETROSPECTIVE STUDY OF THE IMPACT OF MEAN ARTERIAL PRESSURE ON ESTIMATED BLOOD LOSS DURING ENDOSCOPIC SINUS SURGERY

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available The current practice of lowering mean arterial pressure (MAP during endoscopic sinus surgery (ESS is common, but unproven with regard to peer reviewed literature. The controlled hypotension induced is aimed for improved surgical field and lower the blood loss. Lower mean arterial pressures especially for prolonged surgeries may result in end organ hypoperfusion. The authors reviewed all patients who underwent outpatient endoscopic sinus surgery for the diagnosis of chronic sinusitis from January 1, 2012 to December 31, 2012 at Memorial Hermann Hospital – Texas Medical Centre. We individually reviewed case sheets of every patient and documented blood loss as recorded on the anaesthesia record or in the surgical procedure note, among other variables. A total of 326 patients were included in this study. The median estimated blood loss (EBL was found to be 50 ml. The multivariate regression analysis between these three groups showed that EBL was higher in MAP 75 group. The average of EBL in MAP75 group and the average of EBL in MAP 65-70 group is 42% higher than that in MAP>75 group when other variables were fixed. Hence we found the trend toward higher blood loss with lower MAP. The authors conclude that lower MAP does not result in lower EBL in endoscopic sinus surgery. Furthermore, increases in BMI and crystalloid administered during an aesthetic management of these cases correlates with increased estimate blood loss.

    The objective of the present study was to estimate the influence of isolated and combined acute suppurative Highmore maxillary sinusitis on the serum lactoferrin (LF) and interleukin-8 (IL-8) levels in the children. A total of 70 children at the age varying from 4 to 15 years were available for the examination. Twenty of them constituted the control group, 29 presented with acute suppurative Highmore maxillary sinusitis, in 21 cildren this condition was combined with frontitis, ethmoiditis, otitis, and adenoiditis. Serum lactoferrin and interleukin-8 levels were measured by solid phase enzyme-linked immunoassay. It was shown that all the aforementioned forms of rhinosinusitis were associated with a significant increase of the serum LF level, an universal factor inactivating the propagation of bacterial, viral, and fungal pathogens. The level of IL-8 known to activate chemotaxis was increased only in the children presenting with combined forms of suppurative Highmore maxillary sinusitis. It is concluded that this difference can be used for the purpose of dufferential diagnostics of different forms of suppurative maxillary sinusitis. PMID:25588485

    5-Fluorouracil (5-FU) is a commonly used anti-neoplastic agent. 5-FU has been not uncommonly associated with cardiotoxicity, although the many potentially causative mechanisms are yet to be established. Here, we present the case of a 61-year-old gemstone miner who developed symptomatic sinus bradycardia while receiving a continuous 5-FU infusion combined with radiotherapy for locally advanced rectal cancer. This dysrhythmia is an unusual type of 5-FU toxicity, our case being the second described. We review the actions of 5-FU and the various proposed mechanisms of its cardiotoxic effects. PMID:21762335

  20. Radio scanning studies of ear and sinuses

    International Nuclear Information System (INIS)

    Radiophotoscanners are relatively new diagnostic tools. They provide visual images as well as quantitative information about the behavior in the human body of special substances called radionuclides. A preliminary report is presented about the use of a radioactive gas, xenon-133, to study the ventilation of the middle ear and sinuses. At this point these results cannot be considered definitive or conclusive. If standardization and control of variables is achieved, this technique may play an important role in the physiological and pathological assessment of these cavities. (U.S.)

  1. Radiation Therapy of Maxillary Sinus Cancer

    International Nuclear Information System (INIS)

    Purpose: Maxillary sinus cancers usually are locally advanced and involve the structures around sinus. It is uncommon for this cancer to spread to the regional lymphnodes. For this reason, local control is of paramount important for cure. A policy of combined treatment is generally accepted as the most effective means of enhancing cure rates. This paper reports our experience of a retrospective study of 31 patients treated with radiation therapy alone and combination therapy of surgery and radiation. Materials and Methods: Between July 1974 and January 1992, 47 patients with maxillary sinus cancers underwent either radiation therapy alone or combination therapy of surgery and radiation. Of these, only 31 patients were eligible for analysis. The distribution of clinical stage by the AJCC system was 26%(8/31) for T2 and 74%(23/31) for T3 and T4. Eight patients had palpable lymphadenopathy at diagnosis. Primary site was treated by Cobalt-60 radiation therapy using through a 45 .deg. wedge-pair technique. Elective neck irradiation was not routinely given. Of these 8 patients, the six who had clinically involved nodes were treated with definite radiation therapy. The other two patients had received radical neck dissection. The twenty-two patients were treated with radiation alone and 9 patients were treated with combination radiation therapy. The RT alone patients with RT dose less than 60 Gy were 9 and those above 60 Gy were 13. Results: The overall 5 year survival rate was 23.8%. The 5 year survival rate by T-stage was 60.5% and 7.9% for T2 and T3, 4 respectively. Statistical significance was found by T-stage (p30.1). The 5 year survival rate for RT alone and combination RT was 22.5% and 27.4%, respectively. The primary local control rate was 65%(20/31). Conclusion: This study did not show significant difference in survival between RT alone and combination RT. There is still much controversy with regard to which treatment is optimum.

To our knowledge there are no previous reports in the literature of a benign maxillary ameloblastoma extending into the frontal sinuses.

  8. Relation between intraocular pressure and size of transverse sinuses

    International Nuclear Information System (INIS)

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

  9. CT-MPR invaluable in diagnosing odontogenic maxillary sinusitis

    International Nuclear Information System (INIS)

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

    2011-01-01

    Full Text Available Many organisms participate in symbiotic relationships with other organisms, yet studies of symbioses typically have focused on the reciprocal costs and benefits within a particular host-symbiont pair. Recent studies indicate that many ecological interactions involve alliances of symbionts acting together as mutualistic consortia against other consortia. Such interacting consortia are likely to be widespread in nature, even if the interactions often occur in a cryptic fashion. Little theory and empirical data exist concerning how these complex interactions shape ecological outcomes in nature. Here, we review recent work on fungal-fungal interactions between two consortia: (i leaf-cutting ants and their symbiotic fungi (the latter grown as a food crop by the former and (ii tropical plants and their foliar endophytes (the cryptic symbiotic fungi within leaves of the former. Plant characteristics (e.g., secondary compounds or leaf physical properties of leaves are involved in leaf-cutting ant preferences, and a synthesis of published information suggests that these plant traits could be modified by fungal presence. We discuss potential mechanisms for how fungal-fungal interactions proceed in the leaf-cutting ant agriculture and suggest themes for future research.

    ObjectiveTo investigate the risk factors and clinical features of fungal rhinosinusitis. MethodThe preoperative clinical data of the fungal rhinosinusitis and chronic rhinosinusitis patients in our hospital from April 2012 to May 2014 were given a case-control study, and were analyzed by univariate and multivariate Logistic regression.ResultThe difference of age and duration of the two groups were significant (P0.05); the two groups of patients with nasal congestion, runny nose, epistaxis, nasal purulent secretions and new biological proportion of the difference were signiifcant (P0.05). There were signiifcant differences in calciifcation spots, the proportion of unilateral sinus lesions of CT between the two groups (P0.05). The independent risk factors of fungal rhinosinusitis were age, blood cried, calciifcation spots of CT and unilateral sinus lesions, The regression prediction equation was Y=-7.32+1.14X1+4.12X8+4.53X14+2.95X15. TheOR values of blood cried, calciifcation spots of CT and unilateral sinus lesions were far over 1, so the three factors were the strong correlation factors of fungal rhinosinusitis. Histological examination showed that among 54 cases of fungal rhinosinusitiss patients, 16 cases were chronic invasive, 38 cases were noninvasive.ConclusionOver the age of 40 years old, cried blood, calciifcation spots of CT and unilateral sinus lesions are the independent risk factors of fungal rhinosinusitiss, and can be forecasted through the relevant regression equation.%目的:探讨真菌性鼻-鼻窦炎发病的相关因素和临床特征。方法选取2012年4月至2014年5月本院收治的确诊为真菌性鼻-鼻窦炎的患者与同期确诊的慢性鼻-鼻窦炎患者的术前临床资料进行病例对照研究,并进行单因素及多因素Logistic回归分析。结果两组患者年龄、病程比较差异具有显著性(P<0.05),真菌性鼻-鼻窦炎好发于≥40岁年龄段,病程一般<3年。两组患

  15. Value of imaging modalities in sinus tarsi syndrome

    International Nuclear Information System (INIS)

    Sinus tarsi syndrome consists of ankle pain, giving way of the ankle, and tenderness over the sinus tarsi after acute ankle injury (usually inversion). Plan radiographic evaluation is unrewarding. This paper reports on stress CT scanning performed in 25 patients with sinus tarsi syndrome; 18 of these patients also underwent MR imaging; and all patients had routine radiographs. No consistent significant abnormalities were seen on CT. Ligamentous injury of the calcaneofibular or talocalcaneal ligament was suggested on MR images in six cases. Therefore, CT was not helpful in evaluating sinus tarsi syndrome, and the MR findings were present in only one-third of cases, suggesting either that MR imaging is not at present sufficiently accurate to detect all abnormalities or ligamentous injury is not the underlying cause for sinus tarsi syndrome

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

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

    Full Text Available Introduction: Sinusitis is usually treated with antibiotics, decongestants, mucolytics and steroids. Long term use of these drugs has many side effects. This has led to the use of other modalities of treatment such as saline nasal irrigation. Saline nasal irrigation helps in clearance of secretions, debris and crusts, thus improving the mucociliary clearance. OBJECTIVE: This randomized comparative study was undertaken to assess the ciliary function by performing saccharine test and to evaluate the effect of 3.5% hypertonic saline nasal drops against normal saline nasal drops on mucociliary transit time of saccharine. MATERIALS AND METHODS: Fifty patients diagnosed as chronic sinusitis in the age group of 18 to 45 years were randomized into two groups; Group A treated with 0.9% normal saline and Group B with 3.5% hypertonic saline for a period of 4 weeks. Mucociliary transit time was recorded by performing saccharine test before and after treatment. RESULTS: Significant improvement was seen in both the groups but when compared to normal saline, hypertonic saline significantly improved the mucociliary clearance. The mean mucociliary transit time of saccharine in Group A patients before treatment was 19.860 minutes and after treatment was 17.634 minutes (t=14.012, p=0.0001. The mean mucociliary transit time of saccharine in Group B patients before treatment was 21.881 minutes and after treatment was 16.689 minutes (t=14.662, p=0.0001. All the patients reported relief of symptoms, but relief was much earlier in Group B when compared to Group A. Mild burning sensation in the nose and throat was reported by 4% of patients in Group A and 8% in Group B. CONCLUSION: Both 0.9% normal saline and 3.5% hypertonic saline significantly improved the mucociliary clearance. Hypertonic saline is more efficacious than normal saline in the treatment of chronic sinusitis

    Objective Three-dimensional anatomical appreciation of the matrix of the cavernous sinus is one of the crucial necessities for a better understanding of tissue patterning and various disorders in the sinus. The purpose of this study was to reveal configuration of fibrous and adipose components in the cavernous sinus and their relationship with the cranial nerves and vessels in the sinus and meningeal sinus wall. Materials and Methods Nineteen cadavers (8 females and 11 males; age range, 54–89 years; mean age, 75 years) were prepared as transverse (6 sets), coronal (3 sets) and sagittal (10 sets) plastinated sections that were examined at both macroscopic and microscopic levels. Results Two types of the web-like fibrous networks were identified and localized in the cavernous sinus. A dural trabecular network constituted a skeleton-frame in the sinus and contributed to the sleeves of intracavernous cranial nerves III, IV, V1, V2 and VI. A fine trabecular network, or adipose tissue, was the matrix of the sinus and was mainly distributed along the medial side of the intracavernous cranial nerves, forming a dumbbell-shaped adipose zone in the sinus. Conclusions This study revealed the nature, fine architecture and localization of the fine and dural trabecular networks in the cavernous sinus and their relationship with intracavernous cranial nerves and vessels. The results may be valuable for better understanding of tissue patterning in the cranial base and better evaluation of intracavernous disorders, e.g. the growth direction and extent of intracavernous tumors.

    Diagnosing sinusitis remains a challenge for primary care physicians. There is a need for a simple, office-based technique to aid in the diagnosis of sinusitis without the cost and radiation risk of conventional radiologic imaging. We designed a low-cost near-infrared (NIR) device to transilluminate the maxillary sinuses. The use of NIR light allows for greater interrogation of deep-tissue structures as compared to visible light. NIR imaging of 21 patients was performed and compared with computed tomography (CT) scans. Individual maxillary sinuses were scored on a scale from 0 to 2 based on their degree of aeration present on CT and similarly based on the NIR signal penetration into the maxilla on NIR images. Our results showed that air-filled and fluid/tissue-filled spaces can be reasonably distinguished by their differing NIR signal penetration patterns, with average NIR imaging scores for fluid-filled maxillary sinuses (0.93+/-0.78, n=29) significantly lower than those for normal maxillary sinuses (1.62+/-0.57, n=13) (p=0.003). NIR imaging of the sinuses is a simple, safe, and cost-effective modality that can potentially aid in the diagnosis of sinusitis. Long-term, significant device refinement and large clinical trials will be needed to determine the diagnostic accuracy of this technique.

  1. Variations in reciprocal distances between the ethmoidal sinus, sphenoidal sinus and posterior orbit. Measurement on CTscans

    International Nuclear Information System (INIS)

    In concluding surgery of the paranasal sinuses (anterior and posterior) and the sphenoidal sinus, caution is demanded because intraorbital complications may develop in the skull. It is well-known that there is substantial variation in the form of the internal wall of the orbit, and the anterior and posterior walls of the sphenoidal sinus. In the present study, we measured the size of the structure around the paranasal sinus on patient CTscans to be used in surgery on the paranasal sinuses. A total of 387 people (184 males and 203 females) with no destructive bone lesions who visited the Juntendo University Hospital between 1999 and June 2002 were investigated. A plane was selected 14 mm above a line drawn between the medial angle and the external acoustic orifice on CTscans performed using axial projection. This framework was used to conduct the measurements. We employed this method because we consider it ideal for rendering the ethmoidal sinuses, the internal wall of the orbit, medial rectus muscle, optic nerve, and the anterior and posterior walls of the sphenoidal sinus most clearly visible. We measured the length between these anatomically important regions. We measured 1) the length of a line drawn between the opening of the nose and the line drawn between the right and left optic canals, 2) the length between the nasal opening and the posterior wall of the sphenoidal sinus, on the same horizontal line drawn between the posterior end of the eyeball and the nasal septum, 3) the length of a line from the site where the optic nerve adheres to the nasal septum, 4) the length between the lateral wall of the ethmoidal sinus, 5) the length between the nasal septum and the medial side of the medial rectus muscle, 6) the length between the medial side of the medial rectus muscle and the medial side of the optic nerve. The measurements were performed on both sides. We analyzed the above results statistically according to gender and age. The results of the analysis

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis. Methods: Ten patients with intracranial venous sinus thrombosis, confirmed by CT, MRI, MRV and / or DSA and encountered during the period of Aug. 2005-Aug. 2007, were treated with endovascular management after they failed to respond to anticoagulant therapy. Of ten patients, intravenous thrombolysis and mechanical thrombus maceration were carried out in 6, while intravenous thrombolysis, mechanical thrombus maceration together with intra-arterial thrombolysis were employed in 4. After the treatment, the anticoagulant therapy continued for 6 months. The patients were followed up for 12-29 months (mean 21 months). Results: After the treatment, the clinical symptoms and signs were completely or partially relieved in eight patients, including disappearance of headache (n=6) and relive of headache (n=2). No obvious improvement was found in one patient and linguistic function disturbance was seen in the remaining one. Lumbar puncture showed that the cerebrospinal fluid pressure returned to normal in all patients. Neither recurrence of thrombosis nor new symptom of neuralgic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation. Conclusion: Endovascular treatment is an effective and safe procedure for the potentially catastrophic intracranial venous thrombosis. (authors)

  3. Magnetic resonance imaging of the cavernous sinus

    The magnetic resonance (MR) appearance of the cavernous sinus (CS) was studied in 10 normal and 23 abnormal CSs (11 vascular and 12 neoplastic lesions) using T{sub 1}-wighted spin echo images with and without Gd-DTPA. In normal CSs, the intracavernous carotid artery (ICA) was disclosed as an area of signal void that was not enhanced with Gd-DTPA. Most venous flow showed low intensity and was markedly enhanced with Gd-DTPA. Venous flow, however, was heterogeneous, which suggested the distribution of flow velocities. In the carotid-cavernous sinus fistulas (CCFs), the ICA and shunted flow were disclosed as areas of signal void and their relationship was clearly shown. Normal venous flow appeared as a low intensity area even with CCFs. In the cavernous aneurysms, thrombosis and patent arterial flow were shown, but in one case it was impossible to differentiate patent arterial flow from calcification. In neoplastic lesions, CS invasion was suspected by encasement or marked dislocation of the ICA, disappearance of venous flow, and extension of extrasellar tumors to the medial wall and extension of sellar tumors to the lateral wall. MR was found to be a promising diagnostic modality for the evaluation of the CS. (author).

  5. A clinical analysis of maxillary sinus cancer

    International Nuclear Information System (INIS)

    Thirty-two patients (23 males, 9 females) with maxillary sinus cancer were treated at Kyushu University Hospital during 2000-2008. They were classified by T classification as 5 cases with T2, 13 with T3, 12 with T4a, and 2 with T4b. Between 2000 and 2003, 16 patients were given irradiation, intra-arterial 5-fluorouracil (5-FU) infusion chemotherapy, maxillectomy and postoperative irradiation. After 2004, two patients with T4b maxillary sinus cancer were treated by superselective intra-arterial chemotherapy with Cisplatin (CDDP) and Docetaxel (DOC) and irradiation. Other patients were given irradiation and chemotherapy with S-1 and intra-arterial infusion of 5-FU. The 3-year survival rate was 68.3% for all patients. The 3-year survival rate was 74.6% for patients treated after 2004, whereas it was 62.5% for patients treated between 2000 and 2003. Chemotherapy with S-1 or superselective intra-arterial chemotherapy with CDDP and DOC improved cause-specific survival rates. (author)

    Thrombosis of the dural sinus and encephalic veins (CVT) is an infrequent condition accounting for less than 1% of all strokes. Several recent prospective series, in particular the large International Study on Cerebral Vein and Dural Sinus Thrombosis cohort, definitely have shown a more benign prognosis compared with that of arterial strokes: CVT has an acute case fatality of less than 5%, and almost 80% of patients recover without sequelae. However, patients surviving the acute phase of CVT are at risk of a number of complications such as recurrence of any thrombotic events in about 7%, recurrence of CVT in about 2-12%, seizures in 5 to 32%, visual loss due to optic atrophy in percentages that range from less than 1 to 5%, presence of dural fistula (there are no data available about exact frequency) and neuropsychological and neuropsychiatric sequelae characterized by aphasia, abulia and depression. However, there is only little information on the long-term neuropsychological outcome. Studies investigating professional status, cognitive performance, depressive symptoms and quality of life evidenced depression and anxiety in 2/3 of CVT patients despite an apparent good recovery in 87% of these patients. Thus, patients should be encouraged to return to previous occupations and hobbies and reassured about the very low risk of recurrence. PMID:18004061

    The clinical course and pathologic features of a 72 year old female who presented with epistaxis are presented. Radiographic findings were notable for a large, soft tissue lesion filling the maxillary sinus with significant bony erosion and expansion. The patient was ultimately diagnosed with epithelioid hemangioendothelioma (EHE) and underwent endoscopic resection. She has no evidence of local, regional or distant recurrence 14 months post-surgery. The rarity of this neoplasm, the unusual anatomic location and non-specific symptoms present diagnostic and management challenges. Epithelioid vascular tumors encompass a spectrum of benign and malignant tumors. EHE itself is thought to have an intermediate malignant behavior pattern, though cases with indolent behavior have been reported. Differentiation of EHE from other lesions has historically based on histopathology. Additionally, recent studies have described a recurrent genetic fusion WWTR1-CAMTA1 in EHE, involving t(1;3) (p36;q25). This represents the second reported case of EHE arising in a paranasal sinus. The histopathologic findings of this lesion are reviewed. PMID:25963905

  8. Maxillary sinus carcinoma: result of radiation therapy

    International Nuclear Information System (INIS)

    This hundred and sixteen patients with carcinoma of the maxillary sinus received primary therapy consisting of external beam irradiation alone or in combination with surgery and/or chemotherapy at the Department of Radiology, Tokyo Medical and Dental University Hospital, between 1953 and 1982. In our institution, methods of treating cancer of the maxillary sinus have been changed from time to time and showed different control rates and clinical courses. An actuarial 10-year survival rate of 21% has been obtained by the megavoltage irradiation alone as well as 34% actuarial 10-year survival rate by megavoltage irradiation with surgery. After the introduction of conservative surgery followed by conventional trimodal combination therapy, the local control rate has been improved. The amount of functional, cosmetic, and brain damages have been remarkably decreased by this mode of therapy. The actuarial five year survival rate was 67%. In addition, along with the improvement of the local control rate, the control of nodal and distant organ metastases have been emerging as one of the important contributions to the prognosis of this disease

  9. Microbiological diagnostics of fungal infections

    Full Text Available Laboratory tests for the detection of fungal infections are easy to perform. The main obstacle to a correct diagnosis is the correlation between the laboratory findings and the clinical diagnosis. Among pediatric patients, the most common fungal pathogen is Candida. The detection of fungal colonization may be performed through the use of chromogenic culture media, which allows also the identification of Candida subspecies, from which pathogenicity depends. In neonatology, thistest often drives the decision to begin a empiric therapy; in this regard, a close cooperation between microbiologists and clinicians is highly recommended. Blood culture, if positive, is a strong confirmation of fungal infection; however, its low sensitivity results in a high percentage of false negatives, thus decreasing its reliability. Molecular diagnostics is still under evaluation, whereas the detection of some fungal antigens, such as β-D-glucan, galactomannan, mannoprotein, and cryptococcal antigen in the serum is used for adults, but still under evaluations for pediatric patients.http://dx.doi.org/10.7175/rhc.v4i1S.862

    To survive inside a host, fungi have to adapt to a changing and often hostile environment and therefore need the ability to recognize what is going on around them. To adapt to different host niches, they need to sense external conditions such as temperature, pH and to recognize specific host factors. The ability to respond to physiological changes inside the host, independent of being in a commensal, pathogenic or even symbiotic context, implicates mechanisms for sensing of specific host factors. Because the cell wall is constantly in contact with the surrounding, fungi express receptors on the surface of their cell wall, such as pheromone receptors, which have important roles, besides mediating chemotropism for mating. We are not restricting the discussion to the human host because the receptors and mechanisms used by different fungal species to sense their environment are often similar even for plant pathogens. Furthermore, the natural habitat of opportunistic pathogenic fungi with the potential to cause infection in a human host is in soil and on plants. While the hosts' mechanisms of sensing fungal pathogens have been addressed in the literature, the focus of this review is to fill the gap, giving an overview on fungal sensing of a host-(ile) environment. Expanding our knowledge on host-fungal interactions is extremely important to prevent and treat diseases of pathogenic fungi, which are important issues in human health and agriculture but also to understand the delicate balance of fungal symbionts in our ecosystem.

    Squamous cell carcinoma (SCC) is a rare complication observed mainly in chronic, recurrent and untreated primary pilonidal disease. It is associated with poor prognosis, and its recurrence rate after surgery is high. Here we present a patient diagnosed with SCC arising from a neglected pilonidal sinus. A 44-year-old male, who is a heavy truck driver, applied to the hospital with chronic discharge from sacrococcygeal region. He had symptoms of the disease with multiple recurrent abscesses and spontaneous drainage for 10 years. The patient underwent cyst excision and the defect was left open for secondary healing. One year later, the patient was admitted to the hospital with a mass of 3 x 3 cm in the same area. Re-excision and a sigmoid colostomy were performed. The patient died after two years. This case study illustrates that since SCC is a fatal complication of recurrent and long-standing pilonidal sinus, the proper treatment of this disease should be carried out as soon as the diagnosis is established. To this end, we believe, that all pilonidal sinus lesions should be sent for pathologic examination. PMID:24600504

    Full Text Available Fungi are an emerging source of peptide antibiotics. With the availability of a large number of model fungal genome sequences, we can expect that more and more fungal defensin-like peptides (fDLPs will be discovered by sequence similarity search. Here, we report a total of 69 new fDLPs encoded by 63 genes, in which a group of fDLPs derived from dermatophytes are defined as a new family (fDEF8 according to sequence and phylogenetic analyses. In the oleaginous fungus Mortierella alpine, fDLPs have undergone extensive gene expansion. Our work further enlarges the fungal defensin family and will help characterize new peptide antibiotics with therapeutic potential.

    2011-09-01

    Full Text Available Background: Traumatic ulcer is a common form of ulceration occured in oral cavity caused by mechanical trauma, either acute or chronic, resulting in loss of the entire epithelium. Traumatic ulcer often occurs in children that are usually found on buccal mucosa, labial mucosa of upper and lower lip, lateral tongue, and a variety of areas that may be bitten. To properly diagnose the ulcer, dentists should evaluate the history and clinical description in detail. If the lesion is allegedly accompanied by other infections, such as fungal, bacterial or viral infections, microbiological or serological tests will be required. One of the initial therapy given for fungal infection is nystatin which aimed to support the recovery and repair processes of epithelial tissue in traumatic ulcer case. Purpose: This case report is aimed to emphasize the importance of microbiological examination in suspected cases of ulcer accompanied with traumatic fungal infection. Case: A 12-year-old girl came to the clinic of Pediatric Dentistry, Faculty of Dentistry, University of Indonesia on June 9, 2011 accompanied with her mother. The patient who had a history of geographic tongue came with complaints of injury found in the middle of the tongue. The main diagnosis was ulcer accompanied with traumatic fungal infection based on the results of swab examination. Case management: This traumatic ulcer case was treated with Dental Health Education, oral prophylaxis, as well as prescribing and usage instructions of nystatin. The recovery and repair processes of mucosal epithelium of the tongue then occured after the use of nystatin. Conclusion: It can be concluded that microbiological examination is important to diagnose suspected cases of ulcer accompanied with traumatic fungal infection. The appropriate treatment such as nystatin can be given for traumatic fungal infection.Latar belakang: Ulkus traumatic merupakan bentuk umum dari ulserasi rongga mulut yang terjadi akibat trauma

  19. CT characterization of inflammatory paranasal sinus disease in cystic fibrosis

    International Nuclear Information System (INIS)

    Purpose: In patients with cystic fibrosis (CF) the prevalence of paranasal sinus affection approaches 100%. We hypothesized that the hyper viscous mucus reducing mucociliary clearance in CF patients could give sinonasal inflammatory patterns different from those in non-CF patients. We wanted to compare the extent and distribution of paranasal sinus disease and the inflammatory patterns in these two groups of patients. Material and Methods: One-hundred-and-eight CF patients (3-54 years old) and 79 controls (7-51 years old) with paranasal sinus disease confirmed at coronal CT were compared. The extent of disease was noted for each sinus and summed for all sinuses. Inflammatory patterns were identified and classified into: 1) routine surgery group (sporadic, infundibular and ostiomeatal complex (OMC) patterns) and 2) complex surgery group (sinonasal polyposis and sphenoethmoid recess (SER) patterns). Results: CF patients had more widespread sinonasal inflammatory changes and more advanced disease for each sinus. Most CF patients displayed sinonasal polyposis and SER patterns while most controls displayed sporadic, infundibular or OMC patterns. As a result, 67% of CF patients were classified to the complex surgery group, compared to only 19% of controls. Conclusion: The impaired mucociliary clearance in CF causes widespread inflammatory paranasal sinus disease, with inflammatory patterns more often requiring extensive surgery, with a higher risk of cerebrospinal fluid leak or bleeding, or involving areas that are more difficult to reach with the endoscope

  20. Evolution of the Sinus Venosus from Fish to Human

    Directory of Open Access Journals (Sweden)

    Bjarke Jensen

    2014-03-01

    Full Text Available The sinus venosus, the cardiac chamber upstream of the (right atrium, is a severely underinvestigated structure. Yet, its myocardium harbors the cardiac pacemaker in all vertebrates. In human, ectopic pacemaking and subsequent pathologies may originate from sinus venosus-derived myocardium surrounding the coronary sinus and the superior caval vein. In ectothermic vertebrates, i.e., fishes, amphibians and reptiles, the sinus venosus aids atrial filling by contracting prior to the atrium (atria. This is facilitated by the sinuatrial delay of approximately the same duration as the atrioventricular delay, which facilitates atrial filling of the ventricles. In mammals, the sinuatrial delay is lost, and the sinus venosus-derived myocardium persists as an extensive myocardial sheet surrounding the caval veins, which is activated in synchrony with the myocardium of the atria. The caval vein myocardium is hardly of significance in the healthy formed heart, but we suggest that the sinus venosus functions as a chamber during development when cardiac output, heart rate, blood pressure and architecture is much more like that of ectothermic vertebrates. The remodeling of the sinus venosus in mammals may be an adaptation associated with the high heart rates necessary for postnatal endothermy. If so, the endothermic birds should exhibit a similar remodeling as mammals, which remains to be investigated.

  1. Preoperative radiotherapy of maxillary sinus cancer

    International Nuclear Information System (INIS)

    This study was to evaluate the effectiveness of preoperative radiotherapy in maxillary sinus cancer. A retrospective analysis was done for 42 patients with maxillary sinus cancer who were treated with radiation with or without surgery from April 1986 to September 1996. There were 27 male and 15 female patients. Patients' age ranged from 24 to 75 years (median 56 years). Stage distribution showed 2 in T2, 19 in T3, and 21 in T4 lesions. The histologic type was squamous cell carcinoma in 38, undifferentiated carcinoma in 1, transitional cell carcinoma in 1, and adenoid cystic carcinoma in 2 patients, All patients were treated with radiation initially with a dosage range of 50.4-70.2 Gy (median 70.2 Gy) before further evaluation of remnant disease. Eleven patients were given induction chemotherapy (2 cycles of 5-fluorouracil and cisplatin) concurrently with radiotherapy. Six to eight weeks after radiotherapy with or without chemotherapy, computerized tomography (CT) of paranasal sinus was taken to evaluate remnant disease. If the CT finding showed remnant disease, a Caldwell-Luc procedure was done to get the specimen of suspicious lesions. A radical maxillectomy was done if the specimen was proven to contain malignancy. In contrast periodic follow-up examination was done without any radical surgery if the tissue showed only granulation tissue. Follow-up period ranged from 3 to 92 months with a median 16 months. Nine (21.4%) patients showed complete response (CR) and 33 patients (78.6%) showed persistent disease (PER) to initial radiotherapy. Among the 9 CR patients, 7 patients had no evidence of disease (NED), 1 patient had local failure, and 1 patient had regional failure. Among 33 PER patients, salvage total maxillectomy was done in 10 patients, and the surgery was not feasible or refused in 23 patients. Following the salvage radical surgery, 2 patients were NED and 8 patients were PER status. Overall and disease- free survival rate at 5 years was 23.1% and 16

    Full Text Available Background: The coronary sinus is a dilated venous channel opening into the right atrium of the heart. The coronary venous system has gained importance in recent years for electrophysiological procedures like arrhythmia ablation, biventricular pacing and implantation of cardiac pacemakers. The present study aims to study the formation and tributaries of coronary sinus and also the morphology of thebesian valve. Materials and Methods: 30 formalin fixed cadaveric hearts available in the department of Anatomy, Dhanalakshmi Srinivasan Medical College and Hospital, Perambalur, Tamil nadu, was used for the study. The formation and tributaries of coronary sinus were noted. The length of coronary sinus in millimeters was measured from the union of great cardiac vein and left marginal vein upto the opening of the coronary sinus in the right atrium with vernier calipers. The width of the coronary ostium in the right atrium was measured in millimeters with vernier calipers. Results: In 93.33% specimens the coronary sinus was formed by the union of great cardiac vein and left marginal vein. In 3.33% specimens it was formed by the union of great cardiac vein and posterior vein of left ventricle, and in 3.33% specimens it was formed by the union of great cardiac vein and oblique vein of left atrium. The left marginal vein was absent in 2 specimens and small cardiac vein was absent in 1 specimen. The mean length of coronary sinus was 54.98 + 12.2mm. The mean width of coronary sinus ostium was 9.35 + 3.24mm. The Thebesian valve was present in 93.33% specimens and it was semilunar in shape. Conclusion: The knowledge of coronary sinus anatomy will be helpful during electrophysiological procedures.

A cutaneous sinus tract of odontogenic origin is a pathway through the alveolar bone that typically begins at the apex of an infected tooth or of an infected portion of the dental alveolus and empties infected material (pus through the skin. Where as the more common finding of an oral fistula is a pathway from the apical periodontal area of a tooth to the surface of the oral mucous membrane, permitting the discharge of suppurative material. Diagnosis, etiology and treatment are discussed with reference to patient history, clinical examinations, imaging, and treatment perspectives.Keywords: dental abscess, fistula, cutaneous sinus tract, odotogenic infection

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

  6. Aspergillosis of the sphenoid sinus simulating a pituitary tumor

    International Nuclear Information System (INIS)

    Sphenoidal aspergillosis is an unusual cause of sella turcica enlargement. Pituitary abscess secondary to Aspergillus had been reported. In the present case, a woman with sphenoid sinus aspergillosis mimiced a pituitary tumor. This patient survived her infection with intact pituitary function following a transsphenoidal approach. No postoperative amphotericine-B and 5-fluorocytosine were necessary. CT scan revealed a mass occupying the sphenoid sinus extending to the sella turcica. Factors that should alert the clinican to the presence of a sphenoidal and pituitary abscess in a patient with sella turcica enlargement are prior episodes of sinusitis, meningitis and immunosuppression and, as in the present case, hyperglycemia.

    Purpose Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT). Materials and Methods Seventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement. Results Maxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology. Conclusion Based on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.

    Lymphocyte proliferation, mobility and longevity make them prime targets for virus infection. Myeloid cells that process and present environmental antigens to lymphocytes are consequently an important line of defence. Subcapsular sinus macrophages (SSMs) filter the afferent lymph and communicate with B-cells. How they interact with B-cell-tropic viruses is unknown. We analysed their encounter with murid herpesvirus-4 (MuHV-4), an experimentally accessible gammaherpesvirus related to Kaposi's sarcoma-associated herpesvirus. MuHV-4 disseminated via lymph nodes, and intranasally or subcutaneously inoculated virions readily infected SSMs. However, this infection was poorly productive. SSM depletion with clodronate-loaded liposomes or with diphtheria toxin in CD169-diphtheria toxin receptor transgenic mice increased B-cell infection and hastened virus spread to the spleen. Dendritic cells provided the main route to B-cells, and SSMs slowed host colonization, apparently by absorbing virions non-productively from the afferent lymph. PMID:25872742

    In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. PMID:26389051

    Full Text Available Tumors of the nasosinuous tract developed in the air cavities usually present a considerable growing before the patient feel any symptom or sign. Great part of the symptomatology is given due to the invasion of the tumor to neighbour structures such as oral and nasal cavities and orbits. A case of a 62 year-old male patient is presented after being under a dental extraction. A bucco-sinuous communication was diagnosed. It did not respond to different treatments and after some moths an epidermoid carcinoma of the right maxillary sinus appeared. It is of great interest to let this case been known in order to outstand the importance of an early diagnosis to get a better vital prognosis in this kinds of lesions.

    Five cases of dural fistulas of the cavernous sinus are reported. The clinical aspect of this lesion is often misleading in the absence of subjective or objective bruits. The diagnosis is made at angiography which should systematically include the internal and external carotid arteries bilaterally. The goal of this study was to elucidate the great variability of the venous drainage and to correlate it with the clinical symptoms and course. The main problem is to know when and how these fistulas should be treated. Vascular ligatures should not be performed. Therapeutic angiography is the treatment of choice, but should be limited to the following indications: poorly tolerated bruits, severe ophthalmic damage (elevated ocular tension, diminished visual acuity, or oculomotor paralysis), angiographically demonstrated massive arteriovenous shunting, and a high degree of cortical venous reflux. Whatever the indication, the course after embolisation is rarely predictable and in particular the risk of extensive venous thrombosis or recurrence is great.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

  14. The nose, paranasal sinuses and nasopharynx

    International Nuclear Information System (INIS)

    The production of radiographs of a good standard is the first essential in the examination of the sinuses, and this requires a constant attention to detail which is best achieved by a continuing close collaboration between the radiologist and the radiographer. Before examination patients must be asked to remove dentures, hair pins, zip fasteners, earrings and other similar adornments. After surgery or head injury, casualty officer and nurses must be encouraged to remove bandages so that dressings can be taken off before examination to remove artefactual shadows. The timing of sinus radiographs in relation to a possible early pregnancy is irrelevant, but in the case of a known pregnancy it is a sensible general principle for the radiologist to discuss the clinical problem with the doctor involved before the examination is carried out. Whenever possible a specialized unit such as a Lysholm table should be used since it allows accurate replication of positioning and unvarying focus-film distances with a moving grid. If a machine of this type is not available a long cone covering 15 cm at a distance of 65 cm can be used. Fast screen-film combinations should be used and standard exposures for particular views established for each machine. Rare earth screens have some advantages in reducing radiation dosage to the eyes, particularly during tomography. Automatic film processing is preferable to hand processing whenever possible because of the reproducibility of film densities in properly maintained machines. It is essential to use small diaphragms and tight coning to the area of interest because of the loss of detail caused by secondary radiation, and the appearance of the film can be further improved by a metal mask placed next to the cassette

    In this study of 110 cranial cavities from adult cadavers, the superior sagittal sinus was found to divide into two channels. In most cases, the division was associated with a dural partition. Essentially, the variations as observed in this study could be grouped into three types: Type 1 includes those specimens in which the sagittal sinus drains into one lateral sinus and the straight sinus into the other, with no connection between the two. Type 2 includes those specimens in which the superior sagittal sinuses and the straight sinus fork, and the forks from both sinuses join to form the lateral sinuses. Type 3 includes those specimens in which a confluence of sinuses exists, varying from a common pool to merely a potential confluence, depending upon the presence of pads, incomplete partitions, and complete partitions of dura mater. Rare findings previously not reported consist of double straight sinuses draining into one transverse sinus; the superior sagittal sinus dividing into three channels with two transverse sinuses on one side; a transverse sinus originating from a tentorial vein; and drainage of a tentorial vein into the confluence of sinuses.

  19. The value of panoramic radiography in assessing maxillary sinus inflammation

    International Nuclear Information System (INIS)

    To evaluate the value of panoramic radiography in diagnosing maxillary sinus inflammation. A total of 214 maxillary sinuses from 114 panoramic radiographs were assessed in this study. Two independent experienced oral radiologists evaluated the images in random order for sinus inflammation. Using Cone beam CT images as the gold standard, the sensitivity and specificity of panoramic radiography were calculated, and inter- and intraobserver agreement for panoramic interpretation were obtained. The mean sensitivity and specificity of panoramic radiography were 81.0% and 85.6%, respectively. The weighted kappas for inter- and intraobserver agreement of panoramic radiography were 0.56 and 0.60, respectively. Panoramic radiography is a reasonably accurate method for diagnosing maxillary sinus inflammation and can be used for screening. However, additional examinations should be considered in patients with potentially significant pathology.

  20. Comparison of CT and MRI features in sinusitis

    International Nuclear Information System (INIS)

    Objective: To correlate the features of inflammatory changes in the paranasal sinuses on magnetic resonance imaging (MRI) with computed tomography (CT). Methods and patients: One hundred and fourteen patients with histologically proven nasopharyngeal carcinoma (NPC) were staged with both CT and MRI. All CT and MRI images of patients with mucosal thickening but no tumour involvement of the sinuses were retrospectively analysed. Results: There were inflammatory changes in 36 maxillary, 21 sphenoid and 16 ethmoid sinuses. These changes include mucosal thickening, retention cysts, retained secretions, inspissated secretions and dystrophic calcification. MRI is superior to CT in separating thickened mucosa, retained secretions and retentions cysts. Conclusion: It is important to appreciate CT changes of sinusitis and the corresponding spectrum of MRI features. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)
