    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.

  2. 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)

    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.

    Full Text Available 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.

    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

  8. 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

    Chronic rhinosinusitis (CRS) is a common and potentially debilitating disease characterized by inflammation of the sinus mucosa for longer than 12 weeks. Bacterial colonization of the sinuses and its role in the pathogenesis of this disease is an ongoing area of research. Recent advances in culture-independent molecular techniques for bacterial identification have the potential to provide a more accurate and complete assessment of the sinus microbiome, however there is little concordance in results between studies, possibly due to differences in the sampling location and techniques. This study aimed to determine whether the microbial communities from one sinus could be considered representative of all sinuses, and examine differences between two commonly used methods for sample collection, swabs, and tissue biopsies. High-throughput DNA sequencing of the bacterial 16S rRNA gene was applied to both swab and tissue samples from multiple sinuses of 19 patients undergoing surgery for treatment of CRS. Results from swabs and tissue biopsies showed a high degree of similarity, indicating that swabbing is sufficient to recover the microbial community from the sinuses. Microbial communities from different sinuses within individual patients differed to varying degrees, demonstrating that it is possible for distinct microbiomes to exist simultaneously in different sinuses of the same patient. The sequencing results correlated well with culture-based pathogen identification conducted in parallel, although the culturing missed many species detected by sequencing. This finding has implications for future research into the sinus microbiome, which should take this heterogeneity into account by sampling patients from more than one sinus. PMID:26834708

    Fungal rhino-sinusitis is the common clinical disease in otorhinolaryngology, and its inci-dence increased year by year. Based on the fungus′s immunity function condition and the different pathology change of the patient,fungal rhino-sinusitis is divided into two types:invasive and noninvasive fungal rhino-sinusitis. Noninvasive fungal rhino-sinusitis is the most common clinical disease,and functional endonasal si-nus surgery is the major treatment for it. Endoscopic sinus surgery can have a better clinical effect,shorter op-eration time and less invasive can in treatment of fungal sinusitis than Caldwell-Luc surgery and can be popu-larized. To popularize the use of functional endonasal sinus surgery for noninvasive fungal rhino-sinusitis,this article summarized the clinical characteristics of noninvasive fungal rhino-sinusitis and discussed the method, curative effect and precaution of functional endonasal sinus surgery for noninvasive fungal rhino-sinusitis.%真菌性鼻-鼻窦炎是耳鼻喉临床常见疾病,其发病率逐年增高,依据病理特征和患者的免疫功能状态分为侵袭性和非侵袭性。临床上以非侵袭性真菌性鼻-鼻窦炎最为常见,其主要治疗方法为鼻内镜手术。与传统手术相比,鼻内镜术治疗非侵袭性真菌性鼻窦炎临床疗效好,手术时间短,创伤较小,在临床上具有推广意义。为了推广非侵袭性真菌性鼻窦炎的鼻内镜治疗,该文结合非侵袭性真菌性鼻-鼻窦炎的临床特征,就非侵袭性真菌性鼻-鼻窦炎的鼻内镜治疗的手术方法、疗效及常见并发症予以综述。

    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

    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

    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

    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.

    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.

    Full Text Available AIM : To establish the role of Sinusitis as Focal sepsis in Chronic Otitis media active mucosal disease, to emphasizethe need of proper diagnostic endoscopic evaluation and improvement in middle ear mucosal disease status after functional endoscopic sinus surgery.METHODS : 60 Patients in the age groups of 18-49 years Chronic otitis media active mucosal disease were identified and screened for evidence of Focal Sepsis in Pasanasal sinus by Diagnostic Nasal endoscopy andcomputed tomography of paranasal diseases. Then Functional endoscopic sinus surgery was done to clear sinusitis and middle ear mucosal disease status assessed.RESULTS :Evaluation revealed that sinusitis in these patients was the cause for persistent discharge. All patients hadone or more evidence of sinusitis like pus in middle meatus, deviated nasal septum and turbinoseptal deformities,prominent enlarged bullae, enlarged middle turbinate on DNE and CT. The otoendoscopy showed inflamed and boggy middle ear mucosal status. All patients underwent septoplasty/FESS depending on findings. Out of 60 patients 52 patient had improvement in middle ear mucosal status with surgery.In the adult population sinusitis is the most important focal sepsis in case of persistent ear discharge in ChronicOtitis Media active mucosal type of disease.A proper diagnostic nasal evaluation of all Chronic Otitis Media activemucosal type of patients is necessary in comprehensive management of the disease. The clearance of sinusitis hasimproved the middle ear mucosal status. Unilateral ear discharge is associated with sinusitis only on the corresponding side, which is in concurrence with our study. Functional endoscopic sinus surgery has emerged as the best procedure for clearance of sinusitis.

    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.

    The main objectives of this study were to estimate the frequency of chronic maxillary sinusitis of dental origin, and to evaluate the microbiology of odontogenic and non-odontogenic chronic maxillary sinusitis. Aspirates from 59 patients with chronic maxillary sinusitis (47 non-odontogenic, 12 odontogenic), collected during a 3-year period, were microbiologically processed for aerobic and anaerobic bacteria. Moreover, antimicrobial susceptibility was evaluated in the isolated bacteria. In this study, 20 % of chronic maxillary sinusitis cases were associated with a dental origin, and sinus lift procedures were the main aetiological factor. Our microbiological findings showed that all specimens from chronic maxillary sinusitis were polymicrobial. Sixty aerobes and 75 anaerobes were recovered from the 47 cases of non-odontogenic sinusitis (2.9 bacteria per specimen); 15 aerobes and 25 anaerobes were isolated from the 12 patients with odontogenic sinusitis (3.3 bacteria per specimen). The predominant aerobes were Staphylococcus aureus (27) and Streptococcus pneumoniae (16), while the more frequent anaerobes were Peptostreptococcus species (31) and Prevotella species (30). Haemophilus influenzae and Moraxella catarrhalis were absent in sinusitis associated with a dental origin. Overall, 22 % of Staphylococcus aureus isolates were oxacillin-resistant, and 75 % of Streptococcus pneumoniae isolates were penicillin-resistant and/or erythromycin-resistant; 21 % of anaerobic Gram-positive bacteria were penicillin-resistant, and 44 % of anaerobic Gram-negative bacteria were β-lactamase-positive. Vancomycin and quinopristin-dalfopristin had the highest in vitro activity against Staphylococcus aureus and Streptococcus species, respectively; amoxicillin-clavulanate and cefotaxime showed the highest in vitro activity against aerobic Gram-negative bacteria; and moxifloxacin, metronidazole and clindamycin were the most active against anaerobic bacteria.

  15. 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)

    Functional endoscopic sinus surgery (FESS) has almost completely replaced the radical Caldwell-Luc approach. About 20 years after its origin of FESS a comparative study with Caldwell-Luc Surgery (C-L) definitely should be on cards to validate the previous results. To compare the effectiveness of endoscopic middle meatal antrostomy and Caldwell-Luc's surgery in the management of Chronic Maxillary Sinusitis. This is a prospective randomized comparative study based on the analysis of eighty patients who were diagnosed to have chronic, unilateral, maxillary sinusitis and underwent surgery, after a failed trial of conservative management. One year after surgery 44% of the C-L patients and 89% of the FESS patients reported distinct improvement of their symptoms. Both are effective in the management of chronic sinusitis. Endoscopic middle meatal antrostomy is superior to Caldwell-Luc in intraoperative and postoperative parameters. PMID:22754797

    Objective:This paper aims to demonstrate the maxillary mucosa restoration after operation to the nasal fungal sinusitis. Methods Observation by microscopic, transmission electron microscopic and scanning electron microscopic was done to the same parts in the maxillary mucosa 3-4 months before and after the endoscopic sinus surgery in the 24 cases of the nasal fungal sinusitis during 2003-2005. Result: Before the operation, all the cases demonstrated epithelia shedding, proliferation, squamous metaplasia, glandular and fibrous tissue proliferation and lymphocytes infiltration. The microtubule was abnormal and mitochondria diminished,3-4 months after operation, the cavity was clear and smooth and the epithelia complete. The cilia average increased and the cilia lined in the same direction. The structure of microtubules was clear. The mitochondria was elongated and dense. Conclusion: There was no significant difference in the damage on ultramicrostructure of the maxillary mucosa between the chronic nasal sinusitis and chronic nasal fungal sinusitis. It is crucial in the successful recovery that the operation gives a thorough clean to the fungal clot and sinus aeration, and that good cleaning and sinus aeration are maintained after the operation. The ultramicrostructure restoration and the function recovery of mucosa will be achieved after careful cleaning for 3-4 months after operation.%目的:探讨慢性非侵袭性鼻窦真菌病术后鼻窦口黏膜的转归过程.方法:采用鼻内镜手术治疗非侵袭性鼻窦真菌病24例,疗效满意.分别于术前及术后3~4个月取相同部位的上颌窦口黏膜进行光、电镜观察,了解黏膜转归情况.结果:术中黏膜标本见鳞状上皮化生、上皮剥蚀、纤毛脱落、微管结构错乱、线粒体减少.术后3~4个月标本纤毛覆盖面积增加,微管结构正常,线粒体狭长致密.结论:慢性非侵袭性真菌性鼻窦炎的黏膜超微结构损害与普通的鼻窦炎没有明

    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

  4. 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

    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.

  6. 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.

    Objective Patients with diabetes mellitus (DM) are known to be liable to infection. However, the association between diabetes and chronic rhinosinusitis (CRS) has not been well studied. We sought to determine the effects of DM on CRS culture results and quality of life (QOL) after functional endoscopic sinus surgery (FESS). Methods We conducted a retrospective cohort study. Adult CRS patients undergoing FESS were recruited from 10/1/2007 to 12/31/2011. Patient demographics, comorbidities, medication use, Lund-Mackay CT scores were collected prior to FESS. Intraoperative culture was obtained. Preoperative and 1-, 3- and 6-month postoperative QOL was measured by the 22 item Sinonasal Outcome Test (SNOT-22) scores. A mixed effects model was performed for analysis. Results Among the 376 CRS patients included, 19 patients (5.05%) had DM. Compared to non-DM patients, DM patients were significantly more likely to have Pseudomonas aeruginosa (26.32% versus 7.56%, p=0.004) and gram negative rods (26.32% vs. 8.96%, p= 0.013), but there were no significant difference in the prevalence of Staphylococcus aureus; DM patients were also significantly more likely to have nasal polyps and gastroesophageal reflux disease. Additionally, DM patients had significantly less improvement of postoperative SNOT-22 scores from baseline to 6-month follow-up than non-DM patients (adjusted mean=11.14, 95% CI (0.14, 22.15), p=0.047) after adjusting for all the other risk factors for CRS. Conclusion DM patients may be prone to gram negative bacterial sinus infections, and have significantly worse short-term postoperative QOL. Special postoperative care may need to be considered in CRS patients with DM PMID:24415555

  10. 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)

    Sick Sinus Syndrome is a common and refractory arrhythmia, needing further study in which setting up a credible sinus node damage model is important. To explore the feasibility and superiority of an original formaldehyde pinpoint pressing permeation (FPPP) method for building a chronic sinus node damage (CSND) model, 5 rabbits were chosen from 35 as a sham-operation group, and the remaining were randomly divided into two groups: the formaldehyde wet compressing (FWC) group, in which models were established by applying a cotton bud dipped in 20% formaldehyde onto the sinus node (SN) area, and the FPPP group, in which models were established by injecting formaldehyde into the SN area through a self-made pinpointing and injecting electrode. We found that in both groups, the HR at 2 h, 24 h, 1 wk, and 2 wk after modeling decreased compared with premodeling; sinoatrial conduction time, sinus node recovery time, and corrected sinus node recovery time were prolonged compared with premodeling. The indexes mentioned shortened by 2 wk after modeling compared with 2 h in the FWC group, whereas they were stable after modeling in the FPPP group. The modeling achievement ratio in the FPPP group was higher and the death rate was lower. Under light microscope, paraffin sections of the SN tissue and cells showed severe injury in both groups. The results indicate that the CSND models in rabbits can be successfully established by the FPPP method, with higher achievement ratio, lower death rate, better stabilization effect, and less damaging comparing with the traditional method.

    Full Text Available Introduction: The chronic rhinosinusitis (CRS is a pathology that has structural and histological alterations. The association between CRS and the gastroesophageal reflux disease (GERD has been widely discussed in the last years. For this relationship to be confirmed, it is necessary to find evidences that the patients with CRS present a major incidence of GERD, that the physiopathology of both diseases explains the association between them and that the GERD treatment cures or improves the CRS' symptoms. Objectives: To evaluate the incidence of GERD in patients with CRS and a level of improvement of the nasosinusal disease symptoms after treatment with protons pump inhibitors. Methods: Retrospective study with 30 patients with CRS refractory to the clinical treatment and/or nasal cavity polypoid pathology with indication of the paranasal sinuses functional endoscopic surgery. We applied a questionnaire for evaluation of the symptomatology and previous treatment for gastroesophageal reflux. The data were submitted to statistical analysis by the Chi-Square test or Fisher's exact test with a significance of 5%. Results: Out of the patients with GERD, 33% had an improvement of the CRS' symptomatology with medications for treatment of the gastric pathology. Conclusion: It is not possible yet to state that the GER is a factor responsible for the CRS and it must be researched as a cofactor or eliciting factor when there is not other evident etiology. However, there are plausible biological mechanisms for such association.

    The present study included 201 adult patients presenting with exacerbation of chronic maxillary sinusitis. The presence of Chlamydia trachomatis and Chl. pneumoniae was verified by the direct immunofluorescencetechnique and polymerase chain reaction. The study material consisted of swipes und swabs from the mucous membrane of the middle nasal passage. The information from the patients was collected with the use of a questionnaire specially elaborated for the purpose of this study. The correlation relationships were established by means of gamma-statistics. The method is based on the calculation of the integral index characterizing the risk of development of chlamydial infection using the scoring scale for the evaluation of the clinical and anamnestic characteristics of the patients. The assessment of the risk of chlamydial colonization by the anamnestic method makes it possible to enhance the effectiveness of clinical diagnostics of chlamydial infection and thereby provides a basis for the prescription of the adequate anti-chlamydial treatment facilitating reduction of the frequency of complications and preventing dissemination of the causative factor of the disease. Moreover, this approach creates the conditions for the targeted selection of the patients to be referred to the laboratory verification of Chlamydia. Highoperating performance and effectiveness characteristics of the clinic-anamnestic diagnostics make it a method of choice for the wide application in the clinical practice. PMID:27500582

    Full Text Available Background Chronic rhinosinusitis (CRS and asthma are among the most important health-related conditions with evident socio-economic effects. The relationship between asthma and CRS has been considered in medical references for centuries. Previous studies have shown that treatment interventions targeting disease in one part of the airway are effective for general asthma management. However, the effect of endoscopic sinus surgery (ESS in CRS patients with concurrent asthma remains controversial. Therefore, we aimed to assess the effects of ESS on improvement of asthma in CRS patients with concurrent asthma. Objectives The aim of this study was to evaluate the impact of ESS on asthma in CRS patients. Methods Twenty-five CRS patients with asthma who met our inclusion criteria after taking a complete history underwent physical examination and diagnostic nasal endoscopy, and the asthma control test (ACT questionnaire was administered to them. Six months after ESS, the patients’ asthma was again assessed using the ACT questionnaire. Results Overall, the mean ACT score significantly increased from 12.56 at the baseline to 20.71 after a six-month follow up period (0.001. Conclusions Given the remarkable improvement in asthma control levels, ESS can be considered a useful method for treating CRS patients suffering from asthma.

    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

    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.

    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

Methods The clinical data of a patient with NIFS misdiagnosed in our hospital was retrospectively analyzed. Results The patient was misdiagnosed as having allergic rhinitis for having recurrent attacked rhinocnesmus, sneeze, and mass snot. Combined with paranasal sinuses CT detection, the patient was considered as having NIFS, and underwent endoscopic surgery. Pathology result confirmed the diagnosis of NIFS, and the patient received anti-fungi treatment without recurrence during a 5-year follow-up. Conclusion Misdiagnosis of NIFS is mainly due to atypical clinical manifestations and preconceived way of thinking by physicians. When the patient presents suspected symptoms of NIFS, the disease history should be collected thoroughly, and physical examination should be performed carefully for the purpose of timely diagnosis and treatment.

    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.

    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.

    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.

  13. Inter-subject variability in human atrial action potential in sinus rhythm versus chronic atrial fibrillation.

    Full Text Available Human atrial electrophysiology exhibits high inter-subject variability in both sinus rhythm (SR and chronic atrial fibrillation (cAF patients. Variability is however rarely investigated in experimental and theoretical electrophysiological studies, thus hampering the understanding of its underlying causes but also its implications in explaining differences in the response to disease and treatment. In our study, we aim at investigating the ability of populations of human atrial cell models to capture the inter-subject variability in action potential (AP recorded in 363 patients both under SR and cAF conditions.Human AP recordings in atrial trabeculae (n = 469 from SR and cAF patients were used to calibrate populations of computational SR and cAF atrial AP models. Three populations of over 2000 sampled models were generated, based on three different human atrial AP models. Experimental calibration selected populations of AP models yielding AP with morphology and duration in range with experimental recordings. Populations using the three original models can mimic variability in experimental AP in both SR and cAF, with median conductance values in SR for most ionic currents deviating less than 30% from their original peak values. All cAF populations show similar variations in G(K1, G(Kur and G(to, consistent with AF-related remodeling as reported in experiments. In all SR and cAF model populations, inter-subject variability in I(K1 and I(NaK underlies variability in APD90, variability in I(Kur, I(CaL and I(NaK modulates variability in APD50 and combined variability in Ito and I(Kur determines variability in APD20. The large variability in human atrial AP triangulation is mostly determined by I(K1 and either I(NaK or I(NaCa depending on the model.Experimentally-calibrated human atrial AP models populations mimic AP variability in SR and cAF patient recordings, and identify potential ionic determinants of inter-subject variability in human atrial AP

    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

    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.

    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.

    2016-01-01

    Full Text Available Fungal infections of the nose and paranasal sinuses can be categorized into invasive and non-invasive forms. The clinical presentation and course of the disease is primarily determined by the immune status of the host and can range from harmless or subtle presentations to life threatening complications. Invasive fungal infections are categorized into acute, chronic or chronic granulomatous entities. Immunocompromised patients with poorly controlled diabetes mellitus, HIV and patients receiving chemotherapy or chronic oral corticosteroids are mostly affected. Mycetoma and Allergic Fungal Rhinosinusitis are considered non-invasive forms. Computer tomography is the gold-standard in sinonasal imaging and is complimented by Magnetic resonance imaging (MRI as it is superior in the evaluation of intraorbital and intracranial extensions. The knowledge and identification of the characteristic imaging patterns in invasive - and non- invasive fungal rhinosinusitis is crucial and the radiologist plays an important role in refining the diagnosis to prevent a possible fatal outcome.

    Full Text Available Objective: to study trends in the incidence and prevalence of chronic pharyngitis, nasopharyngitis, sinusitis, and rhinitis (CPNSR in differentage groups in Moscow and the Russian Federation (RF in the period 1996 to 2009.Materials and methods. 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.

    Histoplasmosis is a systemic fungal mycosis caused by Histoplasma capsulatum. It is a dimorphic fungus which lives as a saprophyte in the environment and occasionally infects immunosuppressed people. H capsulatum is a ubiquitous fungus present throughout the globe and is more common in the temperate world. Human infection with H capsulatum occurs through respiratory route by inhalation of spores present in the air as droplet nuclei. Pulmonary histoplasmosis is difficult to diagnose, more so in the regions where tuberculosis is endemic, and many infected patients remain asymptomatic. In the case of immunosuppression, clinical symptoms of pulmonary infection may be seen along with chances of dissemination. We report a case of chronic pulmonary histoplasmosis in an immunocompetent individual. PMID:27688988

    Full Text Available 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.

    2014-01-01

    Background The bitter taste receptor T2R38 was recently described to play a role in upper airway innate mucosal defense. When activated by bacterial quorum-sensing molecules, T2R38 stimulates the ciliated epithelial cells to produce nitric oxide (NO), resulting in bactericidal activity and an increase in mucociliary clearance (MCC). Polymorphisms within the T2R38 gene (TAS2R38) confer variability in activation of the receptor yielding dramatic differences in upper airway defensive responses (NO production and accelerated MCC) to microbial stimulation based on genotype. Our objective was to determine whether the non protective TAS2R38 polymorphisms, which render the receptor inactive, correlate with medically recalcitrant chronic rhinosinusitis (CRS) necessitating surgical intervention in the context of known risk factors, and thus identify whether the TAS2R38 genotype is an independent risk factor for patients undergoing functional endoscopic sinus surgery (FESS). Methods CRS patients undergoing primary FESS were prospectively genotyped for TAS2R38. Chi-square analysis was performed on the genotype distribution with respect to other risk factors, including allergies, asthma, nasal polyposis, aspirin sensitivity, diabetes, and smoking exposure. Results Seventy primary FESS patients were genotyped demonstrating a statistically significant skewing from the expected distribution of the general population (p < 0.0383). CRS patients with a particular polymorphism seemed less likely to have allergies, asthma, nasal polyposis, aspirin sensitivity, and diabetes, but this did not demonstrate statistical significance. Conclusion Our investigation suggests that TAS2R38 genotype is an independent risk factor for patients failing medical therapy, necessitating surgical intervention. PMID:24302675

    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.

    2012-01-01

    Background It is estimated that about 10% of the population have IgE antibodies to common inhalant molds. Exposure to fungal allergens could be linked to the presence and persistence of asthma, rhinitis and atopic dermatitis. Mold sensitization is a risk factor for development and deterioration of upper airway allergy, especially chronic rhinosinusitis. We addressed the incidence of mold allergy measured as specific IgE to molds and skin prick tests in chronic sinusitis patients. We assessed prevalence of allergic reactions to mould among surgery treated chronic sinusitis patients. Methods A group of 28 chronic sinusitis patients after surgery were included into the study. Routine medical examination, skin prick tests with common inhaled allergens and extended mold panel (Alternaria alternate, Cladosporium herbarium, Aspergilus fumigatus, Candida albicans, Mucor mucedo, Botrytis cinerea, Rhisopus nigricans, Penicilliumi notatum, Fusarum moniliforme Pullularia pullulans (Allergopharma, Germany), tIgE, asIgE measurement were performed (Phadia, Sweden). All investigated patients were consulted by laryngologist and mycological examination was performed. Results We found that sensitization to at least one allergen was present in 43.8(14/32) of sinusitis patients. The most prevalent was sensitization to house dust mite Dermatophagoides pt., found in 21.8 % (7/32) patients. Positive results of skin prick tests with Candida albicans we observed in 18.8% (6/32), with Alternaria alternate in 15,6% (5/32), Cladosporium herbarium in 6,3% (2/32), Aspergilus fumigatus in 3,13 % (1/32). None of investigated patients presented sensitization to other mold allergens. Microbiological methods demonstrated fungal infection only in 2 patients. Conclusions Almost half of chronic sinusitis patients presented sensitization to at least one allergen. Fungal allergy is relatively rare in chronic sinusitis patients.

  16. Does closure of chronic pilonidal sinus still remain a matter of debate after bilateral rotation flap? (N-shaped closure technique

    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.

    The [symbol: see text] sinus-catheter was used to treat purulent sinusitis with septal perforation or defective septum of the sinuses. The procedure described implies simultaneous introduction of two sinus-catheters the functioning channels of which unite into one output by means of T-joint. The method has been successfully tried in the treatment of exudative and aggravated chronic purulent hemisinusitis (6 cases). The authors hold that communication between nasal sinuses is not a contraindication for sinus-catheter application. This fact widely extends potentialities of its use.

    Objective To study the relationship between 64-slice CT features and chronic rhino sinusitis in children with adenoid hypertrophy. Methods The noses of 125 children with adenoid hypertrophy were scanned by 64-slice CT. The relationship between incidence of chronic rhino sinusitis and the volume of adenoid measured by CT was analyzed statistically. Results Mild adenoid hypertrophy (A/N 0.05). While the moderate or severe hypertrophy is (A/N ≥ 0.61) more likely to cause chronic rhino sinusitis. There is positive correlation between the hypertrophy degree and the incidence of chronic rhino sinusitis(P<0.05). Conclusion The CT features of adenoid hypertrophy is closely related to chronic rhino sinusitis. It is of great significance to treat adenoid hypertrophy timely for the prevention of chronic rhino sinusitis.%目的 探讨腺样体肥大儿童中慢性鼻-鼻窦炎发病情况与其CT表现的关系.方法 对125例腺样体肥大的儿童行常规鼻部64排CT检查,统计分析慢性鼻-鼻窦炎的发生率与CT测量腺样体体积的关系.结果 腺样体轻度肥大(A/N<0.6)与慢性鼻-鼻窦炎发病与否无关(P >0.05).腺样体中重度肥大(A/N≥0.61)的患儿更易合并慢性鼻-鼻窦炎,且呈正相关关系(P <0.05).即随着腺样体肥大程度的增加,慢性鼻-鼻窦炎发病率亦增加.结论 儿童腺样体肥大CT表现与慢性鼻-鼻窦炎密切相关,及时治疗腺样体肥大对预防及治疗慢性鼻-鼻窦炎具有十分重要的意义.

    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...

  5. 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

    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.

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.

    Aspergilloma of the paranasal sinus is a non-invasive form of aspergillosis, most often in the maxillary sinus. This case presents an 86-year-old female with aspergilloma of the left maxillary sinus. The patient's chief complaint was intermittent pain on the left maxillary first premolar area. A radiopacification of the left maxillary sinus was observed on the panoramic radiograph. Cone-beam computed tomography revealed complete radiopacification of the left maxillary sinus and scattered multiple radiopaque mass inside the lesion. Biopsy was performed under local anesthesia. On microscopic examination, numerous fungal hyphae, which branch at acute angle, were observed. The diagnosis was made as an aspergilloma based on the histopathologic examination.

    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

  8. 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.

    Objective To realize the characteristics of occurrence and distribution of osteoma found in patients undergoing endoscopic sinus surgery (ESS) due to chronic rhinosinusitis with or without nasal polyps (CRSwNP/CRSsNP),and to discuss the surgical strategy for this tumor.Methods Clinical data of 520 adult patients undergoing ESS due to CRSwNP/CRSsNP from Nov.2006 to Jan.2010 was analyzed retrospectively.The clinical data included the occurrence and location of osteoma,involvement of lamina papyracea/anterior skull base,surgical strategy for the tumor,surgical complications and so on.Results Osteoma was found in 26 of the 520 cases.The occurrence rate was 5% (26/520 cases),with the size of0.4 cm×0.4 cm ×0.4 cm to 1.5 cm ×1.5 cm× 3.0 cm.Most of them were isolated (23/26) and located in frontal sinus (13 cases) or anterior ethmoid sinus (11 cases).Involvement of anterior skull base and orbital wall was respctively found in 7 and 4 cases.Of all the 26 patients,20 cases were treated with complete endoscopic resection,2 with partial endoscopic resection,and 7 without any intervention.All patients had neither immediate nor long-term postoperative orbit/skull base complications.Conclusions Osteoma is not uncommon in CRSwNP/CRSsNP patients undergoing ESS.This tumor is usually isolated without apparent symptoms and occasionally found in sinus CT.Anterior ethmoid sinus and frontal sinus are most frequently involved.Complete endoscopic resection of the tumor can be achieved in most cases.Under the premise of ensuring sufficient drainage,partial endoscopic resection or nonintervention of the tumor is also acceptable.%目的 了解因慢性鼻-鼻窦炎伴/不伴鼻息肉(chronic rhinosinusitis with or without nasal polyps,CRSwNP/CRSsNP)接受ESS的患者中骨瘤的发病情况、分布特点,讨论其术中处理原则.方法 回顾分析2006年11月~2010年1月因CRSwNP/CRSsNP接受ESS的520例患者中26例患者合并骨瘤的发病情况、术中

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

    Directory of Open Access Journals (Sweden)

    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.

Because the patients had pulsus alternans similar that observed in bigeminy, and because they did not have signs or symptoms of heart failure, we believe the arrhythmias represent intrinsic alterations of the electric activity of the sinus node

    Introduction: The surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. The aim of this study was to evaluate the result of Draf III in a series of patients who underwent this procedure. Materials and Methods: Twenty patients were included in this study. Demographic data, history of prior surgery, asthma, aspirin sensitivity and Lund–Mackay score were recorded. A visual analog scale was used for frontal-related symptoms. Patients were followed for a mean duration of 17.5 months and the patency of the frontal sinus ostium was closely monitored. Results: Fifteen patients with chronic frontal sinusitis, two patients with mucoceles, two with malignancy, and one with osteoma underwent Draf III. The mean symptoms score significantly decreased from 5.9 to 3. No ostial closure was seen in the follow-up period. Among 15 patients with chronic frontal sinusitis, 12 had patent ostia of whom three had significant stenosis. All patients with mucocele and osteoma had patent ostia in the follow-up period but patients with sinonasal malignancy showed significant stenosis. Conclusion: Draf III frontal sinusotomy is successful in alleviating patient symptoms and the frontal sinus neo-ostium will remain patent in long-term follow-up of most patients. Revision surgery will be required in some cases, which seems to be related to the nature of the underlying chronic sinus diseases. PMID:27738610

  5. The Putative Role of Viruses, Bacteria, and Chronic Fungal Biotoxin Exposure in the Genesis of Intractable Fatigue Accompanied by Cognitive and Physical Disability.

    Science.gov (United States)

    Morris, Gerwyn; Berk, Michael; Walder, Ken; Maes, Michael

    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

  9. 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.)

    The sinusitis is an inflammation of one or more breasts peri-nasals. It is common in the months of winter and it can last months or years if it is not treat. At the moment we have several means that try to offer our patients a better treatment. One of these instruments is the low power laser that for their properties to the interaction with the biological tissues offers therapeutic effects on the alive tissues, achieving at the level cellular important changes for a quick answer of the damaged tissue. We intended to demonstrate the effectiveness of the treatment with low power laser in patient with sinusitis. It was carried out an explanatory and retrospective study, where it was applied as treatment the low power laser, for that which a team of model Cuban production Fisser 21. The feminine sex, the affected age group prevailed it was among 36 to 50 years for both groups, the maxillary sinusitis prevailed regarding the frontal. The migraine, the nasal obstruction and the sensation of congestion of the head were present in most of the cases. 75% of the patients' treaties noticed improvement of the symptoms between the 1st and 3rd sessions. At the end 80% cured without necessity of a second treatment cycle. The accompanying symptoms almost disappeared in their entirety. We recommend using the treatment of low power laser, as therapy of first line for the treatment of sinusitis of infectious cause. (Author)

  15. Fungal endocarditis: current challenges.

    2014-10-01

    Whilst it used to affect mostly intravenous drug users and patients who underwent valvular surgery with suboptimal infection control procedures, fungal endocarditis is now mostly observed in patients with severe immunodeficiency (onco-haematology), in association with chronic central venous access and broad-spectrum antibiotic use. The incidence of fungal endocarditis has probably decreased in most developed countries with access to harm-reduction policies (i.e. needle exchange programmes) and with improved infection control procedures during cardiac surgery. Use of specific blood culture bottles for diagnosis of fungal endocarditis has decreased due to optimisation of media and automated culture systems. Meanwhile, the advent of rapid techniques, including fungal antigen detection (galactomannan, mannan/anti-mannan antibodies and β-1,3-d-glucans) and PCR (e.g. universal fungal PCR targeting 18S rRNA genes), shall improve sensitivity and reduce diagnostics delays, although limited data are available on their use for the diagnosis of fungal endocarditis. New antifungal agents available since the early 2000s may represent dramatic improvement for fungal endocarditis: (i) a new class, the echinocandins, has the potential to improve the management of Candida endocarditis owing to its fungicidal effect on yeasts as well as tolerability of increased dosages; and (ii) improved survival in patients with invasive aspergillosis with voriconazole compared with amphotericin B, and this may apply to Aspergillus sp. endocarditis as well, although its prognosis remains dismal. These achievements may allow selected patients to be cured with prolonged medical treatment alone when surgery is considered too risky.

    Maxillary sinusitis due to dental causes is usually secondary to periodontal disease or periapical infection and is commonly associated with mucosal thickening of the floor of the maxillary antrum. Computed tomography (CT) is currently the modality of choice for evaluating the extent of disease and any predisposing factors in patients with symptoms of chronic maxillary sinusitis, but it is unable to diagnose dental disease reliably. The presence of restorative dentistry is, however, easily seen at CT and is associated with both periapical and periodontal disease. We aimed to determine whether its presence at CT may predispose to maxillary sinusitis, and in particular to focal mucosal thickening of the sinus floor characteristic of dental origin. Three hundred and thirty maxillary sinus CT images in 165 patients were reviewed for the presence of restorative dentistry in the adjacent teeth, focal maxillary sinus floor mucosal thickening, any maxillary sinus disease (including complete opacification, air fluid levels, diffuse mucosal thickening, focal mucosal thickening) and evidence of a rhinogenic aetiology (osteomeatal complex pathology, mucosal thickening in other sinuses). One hundred and ninety two sinuses adjacent to restorative dentistry and 178 sinuses not adjacent to restorative dentistry were analysed. Focal floor thickening both with, and without, evidence of a rhinogenic aetiology, was significantly more common adjacent to restorative dentistry. Maxillary sinus disease overall was no more common adjacent to restorative dentistry. This work demonstrated that the presence of restorative dentistry predisposes to focal mucosal thickening in the floor of the maxillary sinus and its presence should prompt clinical and radiographical assessment to exclude dental disease as a source of chronic maxillary sinusitis.

  19. 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.)

    The subjective sensation of the patients and the treatment effect were compared prospec-tively between the no nasal packing group and the common nasal packing group. Method:The patients were divided into no nasal packing group and nasal packing group matched for the type of chronic sinusitis. All patients received operation of functional endoscopic sinus surgery. The patients of no nasal packing group were given thoroughly bleeding control without nasal packing, while the patients of nasal packing group received nasal packing with sponge after hemostatic seaweed covering of wound. The nasal stents in nasal packing group were removed two days after operation, and the other treatments were all identical in the two groups. The clinical symptoms and treatment effect were compared between the two groups using visual analog scale. The levels of headache, rhinal-gia, nasal obstruction, bleeding and nasal secretions volume at different time points, such as 1 day, 2 days and 3 days after operation, were evaluated and compared, as well as the recovering of operative region, such as crusta, secretion, reaction film, mucosal edema, vesicle and blockage of the sinus ostium. Result: At the 1st day after operation, the degrees of headache,rhinalgia and nasal obstructionin the no nasal packing group were milder than the nasal packing group, and the differences have statistical significance. Two days after operation, the degrees of headache, rhinalgia and nasal obstruction, as well as the volume of bleeding and nasal secretionsin the no nasal packing group were milder and lower than the nasal packing group,and the differences have statistical significance. Three days after operation, the differences of the indexes above were not statistically significant. The scores of total bleeding volume during the 3 days after operation showed no statistically significant difference between the two groups. Thirty-four patients were cured in no nasal packing group with the average

    Foreign bodies in paranasal sinuses are very rare and most of them are encountered in the maxillary sinus. These foreign bodies may be organic or inorganic and can enter the maxillary sinus through an oro-antral fistula. The oro-antral fistula is formed by a break in the bony segment of the maxillary sinus floor and usually arises subsequent to maxillary premolar and molar extractions. A 63-year-old female patient evaluated for a nonhealing, left, toothless palate lesion and chronic headache occurring over 4 years. Radiography and computed tomography revealed bone discontinuity in the left floor of the maxillary sinus and calcifications within the antrum. A blue foreign body, later identified as dental impression material, was removed by intranasal endoscopy. A careful oral examination is recommended prior to prosthetic restorations. In addition, paranasal sinus foreign bodies should be surgically removed to prevent secondary soft tissue reactions.

    2014-01-01

    Maxillary sinusitis of odontogenic origin is a well-known condition in both the dental and otolaryngology communities. It occurs when the Schneiderian membrane is violated by conditions arising from dentoalveolar unit. This type of sinusitis differs in its pathophysiology, microbiology, diagnostics and management from sinusitis of other causes, therefore, failure to accurately identify a dental cause in these patients usually lead to persistent symptomatology and failure of medical and surgical therapies directed toward sinusitis. Unilateral recalcitrant disease associated with foul smelling drainage is a most common feature of odontogenic sinusitis. Also, high-resolution CT scans and cone-beam volumetric computed tomography can assist in identifying dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent functional endoscopic sinus surgery or Caldwell-Luc operation is required. The aim of this article is to give a review of the most common causes, symptoms, diagnostic and treatment methods of odontogenic maxillary sinusitis. Search on Cochrane Library, PubMed and Science Direct data bases by key words resulted in 35 articles which met our criteria. It can be concluded that the incidence of odontogenic sinusitis is likely underreported in the available literature.

    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.

    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.

    Full Text Available According to our study, diseases of the nose and paranasal sinuses were found in 59.4% of patients with acute and chronic leukemias. In chronic leukemia purulent-inflammatory diseases had abortive clinical manifestation. In acute leukemia, especially during the induction of remission, purulent-inflammatory diseases of the nose and paranasal sinuses were associated with significant signs of purulent process. Inflammatory diseases of the paranasal sinuses are manifested by pronounced shift of hematological indices of intoxication that indicates increase of autointoxication, disturbance of adaptation mechanisms and transition of adaptive-compensatory immunological reactions in damaging ones.

    1992-05-01

    A total of 57 children aged between 5 and 15 years underwent endoscopic ethmoid surgery for recurrent acute or chronic rhinogenic sinusitis, chronic sinusitis associated with bronchial asthma or chronic bronchitis, early rhinogenous orbital complications and paranasal sinus disease associated with mucoviscidosis. The indications for surgical intervention are based on symptoms, the findings on nasal endoscopy and a CT scan of the paranasal sinuses in the coronal plane. The preoperative examination shows that in childhood there are endoscopically detectable anatomical variations of the ethmoid bone (pneumatised middle nasal concha, reversed curvature of the middle turbinate and contact between the uncinate process and the turbinate) that create the conditions for the development of inflammatory paranasal sinus diseases. Careful elimination of these obstructions can accomplish complete cure of the inflammation, and early orbital complications can be treated effectively by combination of surgery with infusion of antibiotics. All surgery was performed under endotracheal anaesthesia using the endoscopic technique described by Messerklinger. The follow-up period was between 6 and 18 months. With the exception of children suffering from mucoviscidosis, cure of the paranasal sinus disease and rhinomanometrically demonstrable improvement of the nasal breathing was achieved in all cases. On the basis of our results a conservative endoscopic approach is recommended as an effective surgical method for the treatment of paranasal sinus disease in childhood. PMID:1612930

    Full Text Available BACKGROUND: Sinus headache secondary to Chronic Rhinosinusitis refers to episode of pain over the sinus area of the face and is often associated with nasal congestion, rhinorrhea, facial pressure, lacrimation, nausea and sensory sensitivity. Any small lesions or anatomical variations over lateral wall of nose may giv e rise to sinus headache. CT scan play a vital role in accurate assessment of osteomeatal complex area and anatomical variations at this site. AIM: To study anatomical variations of osteomeatal complex area and deviated septum in cases of chronic sinus hea dache secondary to Chronic Rhinosinusitis. MATERIALS AND METHODS : This study was conducted in Jhalawar Medical College, ENT Department between Sept. 2012 to Dec. 2014. In this study 75 patients withchronic sinus headache was selected who had chronic headac he for more than 3 months duration not responding to medical line of treatment and who were willing to undergo function endoscopic sinus surgery. All patients underwent for CT scan para nasal sinus. RESULT: In this study deviated nasal septum was found in 77.33% patients, apart from that it was observed that 54.66% of the sinus headache cases had two or more anatomical variations and 28% had single anatomical variations, out of them commonest finding is concha bullosa followed by enlarge bulla ethmoid, para doxical middle turbinate, medialiseduncinate process, lateraliseduncinate process, prominent aggar nasi cells, haller cells and onodi cells in decreasing order . CONCLUSION: The study of CT scan PNS conclude that Deviated Nasal Septum and anatomical variati ons at lateral wall of nose causes narrowing of osteomeatal complex area which predisposed patients to sino nasal disease and sinus headache

    Inflammatory diseases of the maxillary sinuses affect up to 70% of the adult population. Odontogenic maxillary sinusitis represents 13-86% of the inflammatory processes of maxillofacial area, with the incidence range being explained rather by varying diagnosis criteria than the true incidence difference of odontogenic lesions. The aim of the study was to summarize the clinical and radiological characteristics of odontogenic sinusitis according to patients records in the Department of Maxillofacial Surgery of Omsk Clinical Hospital No11 and the oral surgery department of BUZ GKSP No1 in 2009-2014. A total of 948 records of patient (aged 17 to 68 years) with maxillary sinusitis were identified. X-ray examinations were performed by CT PISASSO TRIO ("KoYo", South Korea) and MSCT Brillians 6 and Brillians 64 ((Philips HealthCare), Netherlands). Images were obtained in axial projection with slice thickness of 0.2-0.6 mm with multiplanar reconstructions (MPR) in a variety of direct and oblique projections. Altogether 664 patients were diagnosed with foreign bodies in the maxillary sinuses (filling material in 569 cases, roots or root fragments? implants, rubber drains, fragments of endodontic instruments in 95 cases). In 284 persons odontogenic cysts were found. Almost every fifth case was complicated by mycotic infection. Analysis of the results showed that only a multidisciplinary approach including dentists, maxillofacial surgeons, otolaryngologists and radiologists, as well as dental volumetric tomography or multislice CT can ensure the correct clinical and radiological approaches to determine the tactics of treatment in patients with sinusitis, reduce the incidence of relapses and chronic inflammatory processes in the maxillary sinuses.

  19. Genetics and Sinus Node Dysfunction

    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.

    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.

    Sporotrichosis is commonly a chronic infection caused by Sporothrix schenckii, a saprophytic fungus and is usually limited to cutaneous and subcutaneous tissues. Disseminated systemic, osteoarticular or pulmonary sporotrichosis have been reported but nasal sinusitis by this fungus is extremely infrequent. Earlier report from southern India documented a case of maxillary sinusitis by Sporothrix schenckii. Here we report a similar case of bilateral maxillary sinusitis in a middle aged female from a village of Bihar, a state in eastern India. She underwent endoscopic maxillary sinus surgery for nasal symptoms and diagnosed to have sporotrichotic infection of maxillary sinuses. The diagnosis was done by mycological and histopathological examination and patient improved under antifungal chemotherapy. PMID:27134873

    In a marked part of patients suffering from acute frontal sinusitis, the symptoms do not resolve after initial therapy (antibiotics and/or trephination). The prolongation of the healing or recurrences may be caused by persistent inflammation or by structural abnormalities at the nasofrontal connection. During the last decade endoscopic surgery (FES) has become a very useful method to restore the frontonasal drainage although long term results of this kind of population are rare. We evaluated the results of endoscopic surgery in two patient groups (total number of 50) both operated after prolongation (persistent symptoms after 4 weeks) of the initial acute phase of the frontal sinusitis. The first group (A, 15 patients, first trephined) was followed-up 4 years, the number of recurrences after the first FES was 60% and in the other group (B, no initial trephination) with over 6 months follow-up, 91% of patients had recurrences. In group A pre- and postoperative CT-scanning was used to determine the possible anatomical variations that could be causing the failures. All but 3 patients showed some kind of abnormal anatomical variation. In group B only preoperative CT was done. In most cases the reasons for recurrences of frontal sinusitis were polyps and/or chronic inflammation at the ethmoidal region.

    We present a case of isolated sinusitis sphenoidalis caused by Trichoderma longibrachiatum, an emerging causal agent of fungal infections with an often fatal outcome. A Trichoderma strain was isolated from secretion obtained from the sinus sphenoidalis of a rhinosinusitis patient and identified by sequence analysis of two loci as Trichoderma longibrachiatum from the Longibrachiatum Clade of the genus Trichoderma. T. longibrachiatum can trigger a fatal pathomechanism in immunodeficient patients, but only rarely causes disease in healthy people. The case presented is unique because the patient was not immunocompromised.

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

    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

    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.

    Sick sinus syndrome refers to a collection of disorders marked by the heart's inability to perform its pacemaking function. Predominantly affecting older adults, sick sinus syndrome comprises various arrhythmias, including bradyarrhythmias with or without accompanying tachyarrhythmias. At least 50 percent of patients with sick sinus syndrome develop alternating bradycardia and tachycardia, also known as tachy-brady syndrome. Sick sinus syndrome results from intrinsic causes, or may be exacerbated or mimicked by extrinsic factors. Intrinsic causes include degenerative fibrosis, ion channel dysfunction, and remodeling of the sinoatrial node. Extrinsic factors can be pharmacologic, metabolic, or autonomic. Signs and symptoms are often subtle early on and become more obvious as the disease progresses. They are commonly related to end-organ hypoperfusion. Cerebral hypoperfusion is most common, with syncope or near-fainting occurring in about one-half of patients. Diagnosis may be challenging, and is ultimately made by electrocardiographic identification of the arrhythmia in conjunction with the presence of symptoms. If electrocardiography does not yield a diagnosis, inpatient telemetry monitoring, outpatient Holter monitoring, event monitoring, or loop monitoring may be used. Electrophysiologic studies also may be used but are not routinely needed. Treatment of sick sinus syndrome includes removing extrinsic factors, when possible, and pacemaker placement. Pacemakers do not reduce mortality, but they can decrease symptoms and improve quality of life.

    Full Text Available Cistos odontogênicos são lesões pouco comuns que podem ocorrer após inflamação da polpa dentária. A abordagem terapêutica destes cistos é realizada em consultórios odontológicos e, dependendo de sua extensão, pode ocasionar a formação de fístula oroantral e rinossinusite crônica. O objetivo deste trabalho é propor o tratamento videoendoscópico do cisto odontogênico com expressão em seio maxilar. Realizou-se um estudo retrospectivo de quatro casos de cistos de origem dentária, com extensão intra-sinusal, complicados com fístula oroantral e sinusite crônica de seio maxilar após curetagem em consultório odontológico. Utilizamos a técnica videoendoscópica via transmaxilar para acessarmos o cisto intra-sinusal. Os quatro pacientes apresentaram resolução do quadro infeccioso e cicatrização da fístula oroantral, sem recidiva durante o seguimento. A cirurgia videoendoscópica é um método seguro e efetivo para tratamento do cisto odontogênico descrito, podendo contribuir para prevenir a formação de fístula oroantral e supuração de seio maxilar.Odontogenic cyst is a common lesion that can happen after inflammation of the dental pulp.

    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).

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

    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.

    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.

    Sinus osteoma is a common nasal and sinus disease, while the clinical cases of osteoma with a diameter greater than 30 millimeter are rarely seen. This paper reports a case of a 39-years-old male patient discovered with one-year long swelling pain in the right eye. The patients' right eye was mildly prominent and he suffered from hypopsia and diplopia. After CT scanned, he have ethmoid osteoma been discovered, besides, the right media rectus compression and orbital apex compression and consequent pathologically were diagnosed. The solid tumor ranged widely from the anterior skull base to the superior and interior orbital walls,and thus deprived the patient's complete surgical resection. As an attempt to prevent complications, most parts of the tumors were sur gically removed.

  11. 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.)

  12. 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

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%.

    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 m...

    @@ Silent sinus syndrome (SSS) is characterized by spontaneous and progressive unilateral enophthalmos with no other symptoms. Maxillary sinus atelectasis displayed on CT will be helpful for clinical diagnosis. The operation for better maxillary sinus ventilation shows good therapeutic effects and prognosis. In 1964, Montgometry1 described the first case of patient whose enophthalmos was caused by mucocele of the maxillary sinus. Since then, all otolaryngologists have taken more and more attention to this syndrome. And by June 2000, a total of 45 cases had been reported worldwide.

    Full Text Available Introduction: The osteomas are osseous lesions with slow and asymptomatic growth that most of the times is a finding in radiological exams requested for other reason. It's the most common benign neoplasm of the paranasal sinuses. The osteomas are located mainly in the frontal sinus (57% to 80%, followed by the ethmoidal sinuses (20%, maxillary sinuses and rarely in the sphenoid sinus. It has a discreet predominance in the male sex 1.5 and its incidence is higher in the 3rd and 4th decades of life. The treatment is surgical no matter the size. Objective: To describe a case of giant osteoma of the ethmoidal sinus including a brief literature review. Case Report: JDA, male, 33 years old, presented with a right constant nasal obstruction for 01 year. Upon exam, he presented with facial asymmetry with lateralization of the right ocular globe. The computed tomography of the paranasal sinuses showed a lesion with density of soft parts occupying partially the right nasal cavity, ethmoid sinus and right maxillary. The patient was submitted to surgery with full exeresis of the lesion. The anatomopathological exam confirmed osteoma. The patient evolved without evidences of the lesion recurrence. Final Comments: The osteomas in the ethmoidal sinus, irrespectively of the size and due to the risk of complications, must be operated.

    We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despite the absence dental symptomatology, the dental origin of sinusitis was discovered. The majority of sinonasal symptoms resolved after appropriate dental treatment, and there was no need for nasal or sinus surgery.

    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.

    2015-10-01

    Olfactory dysfunction is a common complaint for patients with chronic rhinosinusitis, because smell loss decreases a patient's quality of life. Smell loss is caused by obstruction from polyps, nasal discharge, and mucosal edema, as well as inflammatory changes within the olfactory epithelium. Addressing olfaction before endoscopic sinus and skull base surgery is important in order to set postoperative expectations, because an improvement in smell is difficult to predict. Several commercially available olfactory testing measures are available and can easily be administered in clinic. During surgery, careful dissection within the olfactory cleft is recommended in order to optimize postoperative olfactory function.

    OBJECTIVE To investigate the risk factors for chronic obstructive pulmonary disease with pulmonary fungal infections. METHODS 63 cases of chronic obstructive pulmonary disease with pulmonary fungal infections and 92 patients with un-consolidated pulmonary fungal infection were chosen as the research object in the same period. The clinical data were taken for review and analysis. The gender, age, use time of antibiotics and corticosteroids, serum albumin concentration, mechanical situation in the same period, liver and kidney function, and complications were taken for statistical analysis. Patients in the observation group were taken with fluconazole and voriconazole treatment, and were followed up for three months. The effect and prognosis was taken for statistics. RESULTS The age, gender, liver and kidney function in the observation group compared with the control group, there was not significant differences without statistical significance (P> 0.0S). The serum albumin in the observation group was significantly lower than the control group, and the diabetes mellitus type II respiratory failure, and right heart failure was significantly more than the control group. The antibiotic use in patients of the observation group was significantly longer than the control group, long-term use of hormones, and mechanical ventilation were significantly more than in the control group. There was significant difference (P< 0.05). The mechanical ventilation, hypoproteinemia, diabetes and long-term use of antibiotics were the independent risk factors. 63 patients were all taken with pharmaceutical production Ruihui fluconazole and voriconazole treatment, in which 49 cases improved (77.78%), and 14 cases died (22.22%). CONCLUSION The clinical data for diabetes obstructive pulmonary disease with pulmonary fungal infections are taken for analysis. The risk factors of diabetes obstructive pulmonary disease are more complicated. We should take full consideration for these factors, and

    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.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50–70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    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

    Objective To evaluate the risk factors of chronic liver failure(CLF) complicated invnsive fungal infections(IFI) and prevention and treatment. Methods The clinical data and risk factors of 52 patients with CLF complicated IFI were analyzed retrospectively and were compared with those not complicated IFI. Risk factors were analyzed by chi-square test and Logistic regression test and Ridit test. Results In 52 patients with CLF complicated IFI, there were 69 fungal infections in different tissue and organs, the most were in oral cavity, but other tissue and organs especially bellows infections were rising. Candida albieans infeefions were the most, but cryptococcus neoformans infections and aspergillus infections were rising. The risk factors included species of bacteria infections, serum total bilimbin, hospital days, times of antibiotics using, number of invasive operation,species of antibiotics and degrees of aseites. The mortality of patients with CLF complicated IFI were much higher than those not complicated IFI. Conclusion Patients with CLF complicated IFI have poor progress and prognosis. The effective prevent methods are treating primary disease actively, reducing hospital days, detecting patients' body fluids closely, identifying source of infection as early as possible, using antibiotics correctly, reducing or avoiding invasive operation, using immunoactivators and disinfecting air regularly.%目的 探讨慢性肝衰竭(Chronic liver failure,CLF)患者合并侵袭性真菌感染(Invnsivefunsal infections,IFl)的危险因素及防治措施.方法 回顾性分析52例CLF合并IFI患者的I临床特点、危险因素以及预后,并与随机选取同期住院的52例CLF未合并真菌感染患者作为对照.结果 52例真菌感染者发生了69例次不同部位感染,感染部位虽然以浅部口腔为主,但是其他部位感染有上升趋势,尤其是肺部感染;感染真菌种属虽然仍以白色念珠菌为主,但是新型隐

    Four adult patients were diagnosed as having dural sinus thrombosis (DST) by means of magnetic resonance (MR). In the three cases of acute thrombosis, MR disclosed diffuse or segmental hyperintensity in the sinuses involved, which persisted regardless of the sequence and orientation of the plane selected. MR angiography (MRA) provided diagnostic information that proved useful in the chronic case, as well as in the two cases in which follow-up was carried out to determine the degree to which permeability was restored to the sinuses involved. MR diagnosis of DST can produce false positives and negatives, the causes of which should be known, as well as the ways to avoid them, in order to prevent diagnostic errors. MR, when applied and interpreted correctly, can be considered the first, and in many cases the only, choice as a diagnostic method in DST. (Author)

    ABSTRACT A collection of 163 strains of black yeast-like fungi from the CBS Fungal Biodiversity Center (Utrecht, The Netherlands), has been screened for the ability to grow on hexadecane, toluene and polychlorinated biphenyl 126 (PCB126) as the sole carbon and energy source. These compounds were chosen as representatives of relevant environmental pollutants. A microtiter plate-based culture assay was set up in order to screen the fungal strains for growth on the selected xenobiotics versus glucose, as a positive control. Growth was observed in 25 strains on at least two of the tested substrates. Confirmation of substrate assimilation was performed by cultivation on closed vials and analysis of the headspace composition with regard to the added volatile substrates and the generated carbon dioxide. Exophiala mesophila (CBS 120910) and Cladophialophora immunda (CBS 110551), both of the order Chaetothyriales and isolated from a patient with chronic sinusitis and a polluted soil sample, respectively, showed the ability to grow on toluene as the sole carbon and energy source. Toluene assimilation has previously been described for C. immunda but this is the first account for E. mesophila. Also, this is the first time that the capacity to grow on alkylbenzenes has been demonstrated for a clinical isolate. Assimilation of toluene could not be demonstrated for the human opportunistic pathogen Pseudoallescheria boydii (CBS 115.59, Microascales), but the results from microtiter plate assays suggest that strains of this species are promising candidates for further studies. The outstanding abilities of black yeast-like fungi to thrive in extreme environments makes them ideal agents for the bioremediation of polluted soils, and for the treatment of contaminated gas streams in biofilters. However, interrelations between hydrocarbonoclastic and potentially pathogenic strains need to be elucidated in order to avoid the possibility of biohazards occurring. PMID:27019541

    2012-12-01

    Full Text Available Sinus node dysfunction or sick sinus syndrome (SSS includes clinical conditions such as symptomatic sinus bradycardia, sinus pauses or arrest, sinus node exit block, atrial tachycardias and chronotropic incompetence. Even though SSS incidence increases in an exponential-like manner with age, it can occur at all ages, including in the newborn. The mean age of patients with the syndrome is 68 years, with both genders being affected in approximately equal proportion. This condition occurs in 1 of every 600 cardiac patients over 65. Degenerative fibrosis of the tissues of the node has been suggested to be a common cause of SSS. Although it is still disputed. SSS is frequently associated with atrial fibrillation and flutter, tachy-bradycardia syndrome. Tachy-bradycardia syndrome is defined as sinus bradycardia coupled with atrial flutter/fibrillation or reciprocal atrial tachycardia. This syndrome is common in young patients following a surgical treatment of a congenital heart disease. Patients with chronic or persistent atrial flutter/fibrillation show high rates of cardiovascular disorders and mortality while sinus bradycardia is thought as an independent risk factor of atrial flutter/fibrillation. There are certain restrictions to medical treatment: long-term administration of the same medication (sotalol, amiodarone for atrial flutter/fibrillation can cause symptomatic bradycardia while administration of other medication (a class 1 drug increases the likelihood of ventricular arrythmias or evident bradycardia that enhances the risk of sudden cardiac death. Following atrial fibrillation ablation patients saw a significant improvement in the sinus node function, or saw a better sinus node function disrupted due to remodelling that takes place during atrial fibrillation. The surgical methods applications proved most efficient in non-medicational treatment of atrial fibrillation. In the late 1980s American surgeon J. L. Cox developed a so-called Maze

    2013-01-01

    Full Text Available Purpose: The frequency of mycotic infections of the nose and paranasal sinuses has been increasing over the past three decades. Apart from the common causes of fungal rhinosinusitis such as Aspergillus species and Penicillium species, there have been reports of rare and unusual fungi isolated from India and other countries. Objective: The objective of this study is to find out the prevalence of fungal infections of the nose and paranasal sinuses caused by unusual fungal isolates at a tertiary care teaching hospital in South India. Materials and Methods: Duration of the study period was from April 2009 to March 2010. Specimens were collected from the nose and paranasal sinuses of all clinically and radiologically diagnosed cases of rhinosinusitis. All the clinical specimens were processed by standard methods for fungal culture. This included initial screening by 10% potassium hydroxide, inoculation of the specimen onto Sabouraud dextrose agar and incubation at 25°C and 37°C, followed by slide culture and other special techniques wherever necessary. Histopathological examination was also performed for the specimens. Results: A total of 60 specimens were received for fungal culture from cases of rhinosinusitis during the period, out of which 45 showed no growth. There were nine cases of Aspergillus flavus, 1 each of Aspergillus fumigatus and Penicillium species. The rest four specimens grew rare fungal isolates, i.e. Acremonium sp., Scedosporium apiospermun, Cladosporium cladosporioides and Lasiodiplodia theobromae. Histopathological findings were also positive for these four cases. Conclusion: Apart from the common causes, unusual fungal pathogens were isolated from cases of rhinosinusitis during the study period, which is in accordance with similar reports from other parts of India and some other countries.

    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.

    The opening of the frontal sinus is a common occurrence in surgical practice. It may involve many surgical disciplines. The complications that may derive from incorrect treatment of an opened frontal sinus are potentially fatal. Unfortunately, the treatment of patients with injured frontal sinus is not uniform and standardized. Here, we describe our technique of treatment. We propose our treatment modality on the basis of our personal experience, which has been excellent in the past 20 years, that is from the time of the technique's introduction and routine application.

    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)

    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.

    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

    We report a 57-year-old man with intraparenchymal pneumocephalus caused by ethmoid sinus osteoma. He had a history of severe allergic rhinitis, which caused him to frequently blow his nose, and he was referred to our hospital with headache and mild left hemiparesis. CT scans revealed a large volume of intraparenchymal air entrapped in the right frontal lobe related to an osteoma in the ethmoid sinus. The osteoma eroded the upper wall of the sinus and extended into the anterior cranial fossa. At operation, we observed that the osteoma had protruded intracranially through the skull base, disrupted the dura and extended into the frontal lobe. To our knowledge, this is the first report of a patient with intraparenchymal pneumocephalus caused by an ethmoid sinus osteoma.

    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.

    Full Text Available The keratocystic odontogenic tumor (KCOT is a frequently encountered developmental cyst of the jaws. The occurrence of KCOT in the maxillary sinus is rare. The mucosa of the maxillary sinus is susceptible to infections, allergic diseases, and neoplasm. The anatomic position of maxillary premolar and molar teeth is in close contact with the sinus predispose to spreading of pulp and periodontal infection, odontogenic cyst, and tumors to the sinus. Diagnosis and treating KCOT in maxillary sinus is challenging as treatment has to be rendered for sinusitis because of pathology in the sinus and for KCOT. We report a case of 35-year-old female with KCOT involving the lining of the maxillary sinus and put forward hypotheses for the origin of KCOT in the maxillary sinus.

    In order to evaluate the relative role of the automatic nervus system and of the intrinsic electrophysiologic properties on the sinus node function, we measured the corrected sinus node recovery time before and after autonomic nervous system blockade in 24 patients. Fourteen had a sick sinus syndrome, five had a carotid sinus syncope, two had syncope of unknown origin associated with bradycardia. Beta blockade was obtained by infusing metoprolol intravenously at a dosage of 0.2 mg/kg; complete automatic blockade was achieved by further i.v. administration of atropine at a dosage of 0.04 mg/kg. After beta blockade, the corrected sinus node recovery time increased in patients with sick sinus syndrome and intrinsic slow heart rate, whereas it decreased in patients with carotid sinus syncope or with syncope and bradycardia. In patients with sick sinus syndrome and normal intrinsic heart rate the response was variable. A positive direct correlation was found between the changes of the corrected sinus node recovery time induced by beta blockade and those induced by autonomic blockade; that is, both either prolonged or shortened the corrected sinus node recovery time. The changes of the corrected sinus node recovery time after beta blockade alone were inversely correlated with the intrinsic heart rate. We conclude that patients with intrinsic depression of the sinus node have an increased sympathetic tone.

  11. 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

    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

    We hypothesized that normal sinus rhythm-sinus bradycardia is common in young children following extracardiac Fontan. After excluding patients with sinus pauses, junctional rhythm, tachy-brady syndrome, frequent ectopics, or ectopic atrial rhythm, we found an ambulatory 24-h Holter monitor average heart rate of 78 ± 12 beats per minute (bpm) in 33 post-extracardiac Fontan children with a median age of 6 years (5-10). A 24-h average heart rate of 78 ± 12 bpm is statistically significantly lower than a 24-h average heart rate value of 90 ± 10 bpm derived from a similarly aged control population (p < 0.01). We conclude that after excluding those with significant arrhythmias, normal sinus rhythm-sinus bradycardia is common in children post-extracardiac Fontan.

    Biofilms are organized bacterial communities that may be homogeneous or heterogeneous. They play a significant role in the pathogenesis of chronic nasal sinusitis, chronic tonsillitis, cholesteatomas, and device-related infections. Despite this, few studies have been done that examine the presence of bacterial biofilms in tissues from patients with different types of COM or middle ear cholesteatomas. In the current study, we examined the presence of biofilms in surgical tissue specimens from humans with chronic ear infections using scanning electron microscopy (SEM). We hypothesize that bacterial biofilms present differently in patients with different types of chronic otitis media. Our results provide new insights regarding treatment of chronic otitis media. A prospective study was conducted in which middle ear tissues were obtained from 38 patients who underwent tympanoplasty and/or tympanomastoid surgery due to chronic ear infections. A total of 50 middle and mastoid tissue samples were processed for SEM analysis. In addition, 38 middle ear secretion specimens were obtained for routine bacterial culture analysis. Bacterial biofilms were present in 85 % (11 of 13) of patients with middle ear cholesteatoma, 92 % (12/13) of patients with chronic otitis suppurative media (CSOM), and 16 % of patients (2/12) with tympanic membrane perforation (TMP). Fungal biofilms were found in two cases of cholesteatoma. The positive coincidence rate between bacterial biofilms visualized by SEM and bacteria detected by culture was 82 %. Our findings suggest that bacterial biofilms are very common in CSOM and middle ear cholesteatomas. Positive bacterial cultures imply the presence of biofilm formation in CSOM and cholesteatomas. As such, our results provide new insights regarding treatment of chronic otitis media.

    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.

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

  2. 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)

  3. 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.

    Sigmoid sinus diverticulum (SSD) is a rare vascular disorder due to dehiscence of the sigmoid plate. It may be associated with prediverticular venous sinus stenosis (SS) and usually presents as pulsatile tinnitus. The mechanism of development of the SSD and tinnitus from a sinus diverticulum and associated SS is unclear. Previous case reports have suggested that remodeling of the venous system targeting the stenosis, elimination of the diverticulum, or both, have resulted in symptom relief. We present a case of SSD with SS, treated by stenting of the stenosis along with coil embolization of the diverticulum, resulting in complete relief of symptoms. We have also reviewed the literature and discussed the evolution of management from open surgical treatment to endovascular treatment. PMID:27610124

    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.

    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. Key words: Maxillary sinusitis/etiology, odontogenic, computed tomography, maxillary sinus. PMID:25858084

    2011-05-01

    Acute otitis media and acute bacterial sinusitis are 2 of the most common indications for antimicrobial agents in children. Together, they are responsible for billions of dollars of health care expenditures. The pathogenesis of the 2 conditions is identical. In the majority of children with each condition, a preceding viral upper respiratory tract infection predisposes to the development of the acute bacterial complication. It has been shown that viral upper respiratory tract infection predisposes to the development of acute otitis media in 37% of cases. Currently, precise microbiologic diagnosis of acute otitis media and acute bacterial sinusitis requires performance of tympanocentesis in the former and sinus aspiration in the latter. The identification of a virus from the nasopharynx in either case does not obviate the need for antimicrobial therapy. Furthermore, nasal and nasopharyngeal swabs are not useful in predicting the results of culture of the middle ear or paranasal sinus. However, it is possible that a combination of information regarding nasopharyngeal colonization with bacteria and infection with specific viruses may inform treatment decisions in the future.

    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.

    1975-11-01

    Sinus-node recovery times were measured, before and after atropine administration, in 21 patients with the clinical diagnosis of sick-sinus syndrome. The results were compared with those reported by other workers. It is concluded that sinus-node recovery times of more than 1 400 ms are most likely due to sinus-node damage (sick-sinus syndrome); normal recovery times are rare in such patients. The diagnosis of the syndrome is strengthened if the recovery time remains abnormally long even after atropine. Further useful diagnostic information can be obtained from the total stimulation phase (duration until restoration of the basic rhythm), this being overall longer in patients with the syndrome than in normal subjects. The increased incidence of A-V nodal rhythms before restoration of the basic rhythm is another indication of organic damage to the sinus node, especially if it also occurs after atropine. The significance of a recovery time which is prolonged before but normal after atropine is less clear: a raised sensitivity to vagotonic influences may be the determining factor here.

    Electrophysiologic studies were performed in 10 normals and 33 patients with sick sinus syndrome before and after total autonomic blockade with propranolol and atropine. In normals both corrected sinus node recovery time (SNRT) and sinoatrial conduction time (SACT) decreased significantly after autonomic blockade. In patients with sick sinus syndrome the corrected SNRT was abnormal (greater than 450 msec) in 16 (48.5%) cases before and 25 (76%) cases (greater than 285 msec) after autonomic ablation (P less than 0.02). Thirteen of 21 patients (62%) with normal intrinsic heart rate and all 12 cases with abnormally low intrinsic rate after autonomic blockade had abnormal corrected SNRT (greater than 285 msec). Mean SACT measured in 19 patients also shortened significantly following pharmacologic denervation. During control it was prolonged (greater than 226 msec) in 8 patients (44%). After autonomic blockade 2 of 13 patients with normal intrinsic heart rate and 3 of 6 with low intrinsic rate showed abnormal SACT (greater than 151 msec). The data suggest that the majority (76%) of patients with sick sinus syndrome have intrinsic abnormality of sinus node automaticity while in a minority (24%) disturbed autonomic regulation is the pathogenetic mechanism. Patients with normal intrinsic heart rate usually have normal intrinsic SACT, while a significant proportion of those with low intrinsic rate have abnormal perinodal conduction. Subjects with abnormal intrinsic heart rate have more severe disturbances of sinus node function than those with normal intrinsic rate.

    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.

    Ten patients with sick sinus syndrome having repetitive sinus node electrograms during long postpacing pauses were studied during programmed atrial stimulation. Sinus node activity was recorded using a percutaneous catheter electrode. A sinus node electrogram was recorded before the return atrial beat in seven patients; it was similar to the sinus node electrogram observed during postpacing pauses and is clearly identified because sinoatrial conduction time was markedly prolonged following the atrial extra beat. Complete sinoatrial exit block occurred in four patients. (1) Sinus node electrograms were thus validated both during postpacing pauses and during programmed atrial stimulation in most patients with sick sinus syndrome. (2) Sinoatrial conduction time was markedly prolonged after one extrasystole, accounting for supracompensatory atrial return cycles. (3) If it were cumulative following multiple extrasystoles, this effect could constitute the electrophysiologic link between an abnormal response during programmed atrial stimulation and the complete sinoatrial block recorded during the pauses that follow rapid atrial pacing.

    Full Text Available Background: Due to the anatomical variations of the paranasal sinuses and its great importance in sinus surgery, as this area is in very close proximity to vital structures including the optic nerve, carotid artery, and skull base, anatomical knowledge of this area is of high importance. The purpose of this study is defining a full and clear impression of paranasal sinus anatomy and its variations as a model for the human population of the country. Materials and Methods: This study was conducted on 45 cadavers in Isfahan forensic Medicine center during 2010 to 2011. Nasal and paranasal sinuses endoscopic dissection was done with (zero and 30 o lenses (Olympus. The methods of performed dissection were via the Stamberger technique. Results: This study showed that 88.9% (40 cases of middle turbinates were in a typical form, while 6.7% (3 cases were in medial and only 4.4% (2 cases were in the lateral form. We also observed 88.9% (40 cases with Agger nasi cells, 37.8% (17 cases with Onodi cells, 28.9% cases with accessory Ostia of maxillary sinus (13 cases, and 15.6% of the cases (7 cases with concha bullosa.

  16. 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.

    Full Text Available Because of its close anatomic relations with nosal and oral cavitis, the maxillary sinus is the place of most frequent inflammatory diseases of all paranasal sinuses. Introduction: The aim of this study was to establish differences in etiology and treatment of rhinogenic and odontogenic maxillary sinusitis. Materials and methods: In this study, we analyzed the etiology, clinical characteristics of the disease, x-ray findings, clinical course and treatment of 188 cases, which were diagnosed and treated as odontogenic or rhinogenic maxillary sinusitis in the Departments of Maxillofacial surgery and Otorhinolaringology – “St. Anna” Hospital, Sofia from 2005 to 2010. Patients were divided according to age and sex. Data was systematized and analyzed. Results: This study clearly showed that rhinogenic diseases of maxillary sinus are three times more frequent than odontogenic diseases. Also the etiology of odontogenic sinusitis most often is due to mistakes in the treatment of the upper teeth (alien corpuses, perforation after extraction, which is completely different from rhinogenic sinusitis. In the surgical treatment of rhinogenic maxillary sinusitis usually endonasal polypectomy was followed by operation according to Caldwell-Luc or functional sinus endoscopy. During the surgical treatment of odontogenic sinusitis the most frequent intervention was surgical plastic of oral-antral communication with mucogingival vestibular flap followed by operation according to Caldwell-Luck what is different from the treatment of rhinogenic sinusitis.Conclusion: Maxillary sinus often suffers from inflammatory diseases and should always be examined carefully by means of anamnesis, clinic exam and x-rays to identify its origin. Upper teeth should be treated carefully in everyday’s dental practice to avoid being cause of sinusitis.

    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.

    One of the most widely used tests for evaluation of sinus node function is sinus node recovery time (SNRT), which requires right heart catheterization. On the other hand SNRT has high specificity but only moderate sensitivity in the diagnosis of sick sinus syndrome (SSS). The authors studied acute electrophysiologic effects of dipyridamole (0.40 mg/kg IV) in 16 patients with clinical SSS. All of them had normal SNRT and had undergone permanent DDD pacemaker implantation. By the aid of temporary pacing inhibition, the authors noninvasively measured the corrected sinus node recovery time (SNRTc) and sinus cycle length (SCL) before and after dipyridamole administration. SCL was slightly decreased from a mean basal value of 1025 +/-323 to 913+/-213 msec after dipyridamole administration (mean -10%), but this was not statistically significant. SNRTc was increased from a mean basal value of 344+/-91 to 606+/-156 msec after dipyridamole administration (+76% Pnode function. SNRT measurement after intravenous dipyridamole may increase sensitivity of this test in patients with suspected SSS and normal SNRT.

    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

    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.

    Osteoma is a benign tumor that is composed of compact or cancellous bone. It is the most common benign neoplasm of the paranasal sinus, and ethmoid sinuses are the second most common sites of paranasal sinus osteoma. The symptoms of ethmoid sinus osteoma can give rise to various kinds and extent of symptoms. In symptomatic cases, surgical management is necessary, but appropriate surgical approach to the ethmoid sinus is not clearly established. We describe 2 male patients with a diagnosis of blow-out fractures after trauma; ethmoid sinus osteoma on preoperative computed tomography scans was coincidentally found, and the surgical correction was done simultaneously. The purpose of this article was to present the successful surgical removal of ethmoid osteoma through lamina papyracea and transcaruncular approach, resulting in both successful surgical correction and good cosmetic outcome.

    Management of fungal osteomyelitis and fungal septic arthritis is challenging, especially in the setting of immunodeficiency and conditions that require immunosuppression. Because fungal osteomyelitis and fungal septic arthritis are rare conditions, study of their pathophysiology and treatment has been limited. In the literature, evidence-based treatment is lacking and, historically, outcomes have been poor. The most common offending organisms are Candida and Aspergillus, which are widely distributed in humans and soil. However, some fungal pathogens, such as Histoplasma, Blastomyces, Coccidioides, Cryptococcus, and Sporothrix, have more focal areas of endemicity. Fungal bone and joint infections result from direct inoculation, contiguous infection spread, or hematogenous seeding of organisms. These infections may be difficult to diagnose and eradicate, especially in the setting of total joint arthroplasty. Although there is no clear consensus on treatment, guidelines are available for management of many of these pathogens.

    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.

    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.

    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

    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.

    The aim of this study was to explore the mechanism of racemic higenamine in the treatment of sick sinus syndrome (SSS). A total of 40 New Zealand rabbits were randomly divided into normal sinus node and damaged sinus node (SND) groups, and each group was randomly divided into treatment and control groups (n=10). The SND model was established by formaldehyde wet dressing of the sinus node area. The treatment groups were administered an intravenous infusion of 0.04 mg/kg racemic higenamine via the marginal ear vein within 5 min. The electrophysiological indicators of sinoatrial function, including the sinus node recovery time (SNRT), corrected sinus node recovery time (CSNRT), total sinoatrial conduction time (TSACT) and sinus cycle length (SCL), were determined before and 20 min after medication and the changes in these indicators were evaluated. The two control groups were administered 10 ml physiological saline. Following the administration of racemic higenamine, the SNRT, CSNRT, TSACT and SCL in the normal sinus node and SND groups were significantly shortened compared with those in the control groups (Pnode group (Pnode was statistically significant (Pnode self-discipline and improvement of sinoatrial and atrioventricular conduction function.

    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)

    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

    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.

    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.

  19. 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

    Maxillary sinus inflammation, when untreated or incorrectly treated, may extend locoregionally, the remaining paranasal sinuses being the first affected anatomical structures. This is why the understanding of the inflammatory pathology of the maxillary sinus, and particularly of the complications it can generate, is extremely important. The purpose of this presentation is to point out that inflammations of the paranasal sinuses are susceptible to develop complications in certain conditions and threaten the patient's life due to the proximity of vital structures. This is the case of a 16 years old male patient who developed a left maxillary and frontal sinusitis, complicated with cerebral abscess. Early detection, multidisciplinary approach and proper indication of surgical treatment, as well as early suspicion of complication, especially in young male adolescents, are extremely important.

  1. Natural Sources as Innovative Solutions Against Fungal Biofilms.

    Science.gov (United States)

    Girardot, Marion; Imbert, Christine

    2016-01-01

    Fungal cells are capable of adhering to biotic and abiotic surfaces and form biofilms containing one or more microbial species that are microbial reservoirs. These biofilms may cause chronic and acute infections. Fungal biofilms related to medical devices are particularly responsible for serious infections such as candidemia. Nowadays, only a few therapeutic agents have demonstrated activities against fungal biofilms in vitro and/or in vivo. So the discovery of new anti-biofilm molecules is definitely needed. In this context, biodiversity is a large source of original active compounds including some that have already proven effective in therapies such as antimicrobial compounds (antibacterial or antifungal agents). Bioactive metabolites from natural sources, useful for developing new anti-biofilm drugs, are of interest. In this chapter, the role of molecules isolated from plants, lichens, algae, microorganisms, or from animal or human origin in inhibition and/or dispersion of fungal biofilms (especially Candida and Aspergillus biofilms) is discussed. Some essential oils, phenolic compounds, saponins, peptides and proteins and alkaloids could be of particular interest in fighting fungal biofilms. PMID:27115410

  2. 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)

    2014-01-01

    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.

  4. 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

  5. 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

    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

    Fungi cause a wide spectrum of fungal diseases of the upper and lower airways. There are three main phyla involved in allergic fungal disease: (1) Ascomycota (2) Basidiomycota (3) Zygomycota. Allergic fungal rhinosinusitis (AFRS) causes chronic rhinosinusitis symptoms and is caused predominantly by Aspergillus fumigatus in India and Bipolaris in the United States. The recommended treatment approach for AFRS is surgical intervention and systemic steroids. Allergic bronchopulmonary aspergillosis (APBA) is most commonly diagnosed in patients with asthma or cystic fibrosis. Long term systemic steroids are the mainstay treatment option for ABPA with the addition of an antifungal medication. Fungal sensitization or exposure increases a patient's risk of developing severe asthma and has been termed severe asthma associated with fungal sensitivity (SAFS). Investigating for triggers and causes of a patient's asthma should be sought to decrease worsening progression of the disease. PMID:26776889

  8. THE EFFECT OF NORMAL SALINE AND 3.5% HYPERTONIC SALINE ON MUCOCILIARY CLEARANCE IN SINUSITIS

    Directory of Open Access Journals (Sweden)

    2014-10-01

    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

  9. 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

    Between January 1980 to December 1985, 248 patients with advanced squamous cell carcinoma of the pyriform sinus were retrospectively analysed. Criteria for inclusion in the study were the following: no previous treatment and treatment combining total pharyngolaryngectomy and postoperative radiotherapy. Mean follow up was 5 years with a minimum of 3 years. Seventy-one patients had a local regional recurrence (27,4%). Clinical staging at presentation and residual tumor at the primary site after surgery were factors significantly associated with higher local failure rates. The 5 year survival rate was 33 % and the median survival time was 32 months (plateau was reached after thee 6th year). The most frequent severe complication observed was pharyngeal stenosis occurring in 6 % of the cases. This study confirms the poor prognosis of squamous cell carcinoma of the pyriform sinus, in spite of the combination of radical surgery and high dose postoperative radiotherapy.

    2015-10-01

    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

  14. 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.

  15. 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

  16. 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

  17. 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

    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.

  20. MORPHOLOGICAL STUDY OF CORONARY SINUS IN HUMAN CADAVERIC HEARTS

    Directory of Open Access Journals (Sweden)

    R. Manoranjitham

    2015-09-01

    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.

    2012-08-01

    Diseases caused by fungi are increasingly impacting the health of the human population and now account for a large fraction of infectious disease complications in individuals with impaired immunity or breached tissue defenses. Antifungal therapy is often of limited effectiveness in these patients, resulting into treatment failures, chronic infections and unacceptable rates of mortality, morbidity and their associated costs. Consequently there is a real medical need for new treatments and preventive measures to combat fungal diseases and, toward this goal, safe and efficacious vaccines would constitute major progress. After decades of complacency and neglect of this critically important field of research, remarkable progress has been made in recent years. A number of highly immunogenic and protective vaccine formulations in preclinical setting have been developed, and at least two have undergone Phase 1 clinical trials as preventive and/or therapeutic tools against candidiasis.

    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

    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.

    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.

    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.

    Full Text Available Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT and also cone beam computed tomography (CBCT are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported.

    Full Text Available The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses.

    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.

    2011-12-01

    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 .

    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.

    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.

    Sinus nodal cells can generate a diastolic or "pacemaker" depolarization at the end of an action potential driving the membrane potential slowly up to the threshold for firing the next action potential. It has been proved that adult cardiac stem cells (CSCs) can differentiate into sinus nodal cells by demethylating agent. However, there is no report about adult CSCs-derived sinus nodal cells with pacemaker current (the funny current, I f). In this study, we isolated the mouse adult CSCs from mouse hearts by the method of tissue explants adherence. The expression of c-kit protein indicated the isolation of CSCs. Then we co-cultured mouse CSCs with mouse sinus node tissue to induce the differentiation of these CSCs into sinus node-like cells, which was proved by identifying the enhanced expression of marker proteins cTnI, cTnT and α-Actinin with Immunofluorescence staining. At the same time, with whole-cell patch-clamp we detected the I f current, which can be blocked by CsCl, in these differentiated cells. In conclusion, by confirming specific I f current in the induced node-like cells, our work shows a method inducing differentiation of CSCs into sinus node-like cells, which can provide helpful information for the further research on sick sinus syndrome.

    In the last few decades, aerially transmitted human fungal pathogens have been increasingly recognized to impact the clinical course of chronic pulmonary diseases, such as asthma, cystic fibrosis or chronic obstructive pulmonary disease. Thanks to recent development of culture-free high-throughput sequencing methods, the metagenomic approaches are now appropriate to detect, identify and even quantify prokaryotic or eukaryotic microorganism communities inhabiting human respiratory tract and to access the complexity of even low-burden microbe communities that are likely to play a role in chronic pulmonary diseases. In this review, we explore how metagenomics and comparative genomics studies can alleviate fungal culture bottlenecks, improve our knowledge about fungal biology, lift the veil on cross-talks between host lung and fungal microbiota, and gain insights into the pathogenic impact of these aerially transmitted fungi that affect human beings. We reviewed metagenomic studies and comparative genomic analyses of carefully chosen microorganisms, and confirmed the usefulness of such approaches to better delineate biology and pathogenesis of aerially transmitted human fungal pathogens. Efforts to generate and efficiently analyze the enormous amount of data produced by such novel approaches have to be pursued, and will potentially provide the patients suffering from chronic pulmonary diseases with a better management. This manuscript is part of the series of works presented at the "V International Workshop: Molecular genetic approaches to the study of human pathogenic fungi" (Oaxaca, Mexico, 2012).

    The purpose of this study was to find out whether transesophageal pacing could be utilized for assessment of sinus node function in patients with sick sinus syndrome (SSS). In 17 patients with SSS (study group) we compared the results of sinus node tests obtained both in the basal state and after pharmacological autonomic blockade by endocavitary stimulation and, 24 hours later, by transesophageal pacing. In another group of 17 patients with SSS (control group), we compared the results obtained by two endocavitary studies. In "study group", sinus cycle length (SCL) and corrected sinus node recovery time (CSRT) did not show significant differences between the two studies both in the basal state and after autonomic blockade, whereas sinoatrial conduction time (SACT) was more prolonged during esophageal pacing (P less than 0.01). In "control group", sinus node measures did not show significant differences between the two studies. In the "study group," the following coefficients of correlation were obtained in the basal state; SCL, r = 0.65, CSRT, r = 0.57, SACT, r = 0.52 and after autonomic blockade: SCL, r = 0.95, CSRT, r = 0.62 and SACT, r = 0.53. In the basal state, the correlation for SCL and CSRT between the two studies was lower in the "study group" than in the "control group" (P less than 0.05), whereas after autonomic blockade the correlation for sinus node measures did not show significant differences between the two groups of patients. These data suggest that transesophageal study influences the autonomic tone regulating the sinus node; however, it is not responsible for important variations in sinus node measures.(ABSTRACT TRUNCATED AT 250 WORDS)

    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

    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.

    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.

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

    Patients with episodic sinus tachycardia and associated orthostatic intolerance present a diagnostic and management dilemma to the clinician. We define this group of disorders to include sinus node reentrant tachycardia (SNRT), inappropriate sinus tachycardia (IAST), and postural orthostatic tachycardia syndrome (POTS). After a brief review of the current understanding of the pathophysiology and epidemiology of this group of disorders, we focus on the diagnosis and management of IAST and POTS. Our approach attempts to recognize the considerable overlap in pathophysiology and clinical presentation between these two heterogeneous conditions. Thus, we focus on a mechanism-based workup and therapeutic approach. Sinus tachycardia related to identifiable causes should first be ruled out in these patients. Next, a basic cardiovascular and autonomic workup is suggested to exclude structural heart disease, identify a putative diagnosis, and guide therapy. We review both nonpharmacologic and pharmacologic therapy, with a focus on recent advances. Larger randomized control trials and further mechanistic studies will help refine management in the future.

    2006-01-01

    Full Text Available In order to determine the risk factors of odontogenic maxillary sinusitis, a total number of 40 patients with this pathological condition was examined in three-year period. Oroantral communication was detected in 40% of patients, oroantral fistula in 25%, sinus foreign bodies in 15% and other pathological conditions in 10% of cases. The extraction of the upper lateral teeth was the cause of odontogenic sinusitis in 65% patients. Given the specific tooth, the first upper molar was the most common cause of the condition, i.e. in 40% of cases. It may be concluded that odontogenic sinusitis is the complication of the oral cavity surgery in 85% of patients, what should be taken into consideration in prevention.

    Full Text Available Background: Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic, etiologic, radiological and prognostic characteristics were evaluated. Results: The patients' mean age was 34.01±10.25. Eighty seven (70.16% were women and 37 (29.83% were men. The most frequent clinical manifestations were headache, papilledema and seizures. Fifty seven (65.51% women took oral contraceptive pills. Twenty of 57 women (35.08% took the pill longer than one month to be able to fast in Ramadan or perform the Hajj ceremonies. In the mean time they developed cerebral venous-sinus thrombosis. Superior sagital sinus, with or without lateral sinuses, was the most involved area (70.96%. High mortality and morbidity rates (14.51% and 35.48%, respectively were found in patients. Poor prognostic factors at the time of admission were stupor and coma (P=0.001 and evidence of hemorrhage in primary CT scan (P=0.005. Conclusion: Taking oral contraceptive pills was a main factor associated with cerebral venous-sinus thrombosis. Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Health care policy makers should design a plan to warn susceptible women of the risk of cerebral venous-sinus thrombosis, and to educate them the ways to prevent it

    Maw Pin Tan

    Full Text Available Carotid sinus syndrome is the association of carotid sinus hypersensitivity with syncope, unexplained falls and drop attacks in generally older people. We evaluated cardiac sympathetic innervation in this disorder in individuals with carotid sinus syndrome, asymptomatic carotid sinus hypersensitivity and controls without carotid sinus hypersensitivity.Consecutive patients diagnosed with carotid sinus syndrome at a specialist falls and syncope unit were recruited. Asymptomatic carotid sinus hypersensitivity and non-carotid sinus hypersensitivity control participants recruited from a community-dwelling cohort. Cardiac sympathetic innervation was determined using Iodine-123-metaiodobenzylguanidine (123-I-MIBG scanning. Heart to mediastinal uptake ratio (H:M were determined for early and late uptake on planar scintigraphy at 20 minutes and 3 hours following intravenous injection of 123-I-MIBG.Forty-two subjects: carotid sinus syndrome (n = 21, asymptomatic carotid sinus hypersensitivity (n = 12 and no carotid sinus hypersensitivity (n = 9 were included. Compared to the non- carotid sinus hypersensitivity control group, the carotid sinus syndrome group had significantly higher early H:M (estimated mean difference, B = 0.40; 95% confidence interval, CI = 0.13 to 0.67, p = 0.005 and late H:M (B = 0.32; 95%CI = 0.03 to 0.62, p = 0.032. There was, however, no significant difference in early H:M (p = 0.326 or late H:M (p = 0.351 between the asymptomatic carotid sinus hypersensitivity group and non- carotid sinus hypersensitivity controls.Cardiac sympathetic neuronal activity is increased relative to age-matched controls in individuals with carotid sinus syndrome but not those with asymptomatic carotid sinus hypersensitivity. Blood pressure and heart rate measurements alone may therefore represent an over simplification in the assessment for carotid sinus syndrome and the relative increase in cardiac sympathetic innervation provides additional clues to

    AIM: To elucidate the relationship between lymph nodesinuses with blood and lymphatic metastasis of gastric cancer.METHODS: Routine autopsy was carried out in the randomlyselected 102 patients (among them 100 patients died ofvarious diseases, and 2 patients died of non-diseasedreasons), their superficial lymph nodes locating in bilateralnecks (include supraclavicle), axilla, inguina, thorax, andabdomen were sampled. Haematoxylin-Eosin staining wasperformed on 10 % formalin-fixed and paraffin-embeddedlymph node tissue sections (Sum). The histological pattemsof the lymph sinuses containing blood were observed underlight microscope. The expression of CD31, a marker forendothelial cell, was detected both in blood and non-bloodcontaining lymph node sinuses with the method ofimmunohistochemistry.RESULTS: Among the 1322 lymph nodes sampled fromthe autopsies of 100 diseased cases, lymph node sinusescontaining blood were found in 809 lymph nodes sampledfrom 91 cases, but couldn't be seen in the lymph nodessampled from the non-diseased cases. According to histology,we divided the blood containing lymph node sinuses intofive categories: vascular-opening sinus, blood-deficient sinus,erythrophago-sinus, blood-abundant sinus, vascular-formative sinus. Immunohistochemical findings showed thatthe expression of CD31 was strongly positive in vascular-formative sinuses and some vascular-opening sinuses whileit was faint in blood-deficient sinuses, erythrophago-sinusesand some vascular-opening sinuses. It was almost negativein blood-abundant sinus and non-blood containing sinus.CONCLUSION: In the state of disease, the phenomenonof blood present in the lymph sinus is not uncommon. Bloodcould possibly enter into the lymph sinuses through thelymphaticovenous communications between the veins andthe sinuses in the node. Lymph circulation and the bloodcirculation could communicate with each other in the lymphnode sinuses. The skipping and distal lymphatic metastasisof gastric cancer may

The case was a 33-year-old woman with a history of controlled complex partial seizure who presented with headache, asthenia, and uncontrolled seizure for one month. She was febrile and a brain CT scan indicated hemorrhagic focus in the left posterior parietal and the temporal lobe. Magnetic resonance imaging and magnetic resonance venography also proved venous sinus thrombosis in the left transverse sinus. Besides [In addition], a laboratory assessment confirmed brucellosis. Following the treatment with anti-coagulant, anti-brucellosis, and anti-epileptic agents, the patient was discharged in good condition with medical orders. Clinical suspicion and accurate evaluation of a patient′s history is the most important clue in diagnosis and treatment of brucellosis and cerebral venous sinus thrombosis, especially in uncontrolled seizure in patients who had previously been under control.

    Manual segmentation of computed tomography (CT) datasets was performed for robot-assisted endoscope movement during functional endoscopic sinus surgery (FESS). Segmented 3D models are needed for the robots' workspace definition. A total of 50 preselected CT datasets were each segmented in 150-200 coronal slices with 24 landmarks being set. Three different colors for segmentation represent diverse risk areas. Extension and volumetric measurements were performed. Three-dimensional reconstruction was generated after segmentation. Manual segmentation took 8-10 h for each CT dataset. The mean volumes were: right maxillary sinus 17.4 cm(3), left side 17.9 cm(3), right frontal sinus 4.2 cm(3), left side 4.0 cm(3), total frontal sinuses 7.9 cm(3), sphenoid sinus right side 5.3 cm(3), left side 5.5 cm(3), total sphenoid sinus volume 11.2 cm(3). Our manually segmented 3D-models present the patient's individual anatomy with a special focus on structures in danger according to the diverse colored risk areas. For safe robot assistance, the high-accuracy models represent an average of the population for anatomical variations, extension and volumetric measurements. They can be used as a database for automatic model-based segmentation. None of the segmentation methods so far described provide risk segmentation. The robot's maximum distance to the segmented border can be adjusted according to the differently colored areas.

    Cope, E K; Lynch, S V

    2015-03-01

    The human microbiome, i.e. the collection of microbes that live on, in and interact with the human body, is extraordinarily diverse; microbiota have been detected in every tissue of the human body interrogated to date. Resident microbiota interact extensively with immune cells and epithelia at mucosal surfaces including the airways, and chronic inflammatory and allergic respiratory disorders are associated with dysbiosis of the airway microbiome. Chronic rhinosinusitis (CRS) is a heterogeneous disease with a large socioeconomic impact, and recent studies have shown that sinus inflammation is associated with decreased sinus bacterial diversity and the concomitant enrichment of specific sinus pathogens. Here, we discuss the potential role for probiotic supplementation for CRS in light of this increasing understanding of the airway microbiome and microbial interactions with the host. We focus on the ecological significance of microbiome-based probiotic supplementation and potential interactions with the gastrointestinal tract and consider microbial administration methods for treatment of CRS.

    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.

    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

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is the most frequent primary malignant tumor of the liver. It is usually seen in the 6th and 7th decades of life and chronic hepatitis B is the most frequent cause. Extrahepatic metastasis of HCC is an indicator of a poor prognosis and the most common sites are lungs, bones, lymph nodes, kidneys and adrenal glands. We reported a case of isolated metastasis in the right maxilla, which had been found initially, before the tumor in the liver was diagnosed. Case report. A 70-year-old man underwent dental surgery of the upper right molar. Prolonged bleeding control was difficult for up to two weeks, so the biopsy was performed. Histopathological analysis revealed a metastatic hepatocellular carcinoma. Computerized tomography (CT of the abdomen revealed a diffusely heterogeneous liver parenchyma with irregular borders and two foci of mass lesions. There were metastasis in the spleen and also two pathological retroperitoneal lymph nodes were detected, but no ascit, liver cirrhosis, cholestasis or portal vein thrombosis were seen. CT of the orbital and maxillary regions revealed a tumor mass in the right maxillary sinus, spreading to the alveolar sinus, nasal cavity and partially infratemporal space. A tumor mass was in the right orbit as well, infiltrating the surrounding bones and muscles. Clinically, there was proptosis of the right eye accompanied by amaurosis. The treatment started with chemotherapy based on 5-fluorouracil (sorafenib was not available. After three cycles, control CTs showed a stable disease in the liver, but progression in the right maxillary sinus and orbit. Enucleation of the right eye was performed and postoperative radiotherapy was planed. The patient deteriorated rapidly and died, about 6 months after the disease had been diagnosed. Conclusion. Extrahepatic metastasis of HCC represents a progressive phase of the disease with poor prognosis, so the main aim of the treatment should be

    Cerebral sinus-vein thrombosis may lead to severe hemodynamic changes, elevated intracranial pressure (ICP), and brain edema. It is supposed that progression of the thrombus from the sinus into bridging and cortical veins plays a key role in the development of these pathophysiological changes, but this hypothesis lacks experimental proof. The aim of this study, using a novel animal model of sinus-vein thrombosis, was to evaluate the effects of a standardized occlusion of the superior sagittal sinus and its bridging and cortical veins on hemodynamic alterations, on brain water content, and on ICP in domestic pigs. In 10 animals, the middle third of the superior sagittal sinus was occluded with a catheter-guided balloon. Five of these pigs received an additional injection of 1 ml fibrin glue into the superior sagittal sinus anterior to the inflated balloon, leading to an obstruction of bridging and cortical veins. In five control animals the balloon was inserted but not inflated. Five pigs underwent cerebral angiography. Four hours after occlusion, the brains were frozen in liquid nitrogen, and coronal slices were examined for Evans blue dye extravasation, regional water content, and histological changes. Occlusion of the superior sagittal sinus alone did not affect ICP or cerebral perfusion pressure (CPP). The additional injection of fibrin glue caused an obstruction of cortical and bridging veins as well as severe increases in mean (+/- standard deviation) ICP to 49.4 +/- 14.3 mm Hg, compared with 8.3 +/- 4.5 mm Hg in sham-treated controls and 7.1 +/- 3.9 mm Hg in animals with occlusion of the superior sagittal sinus alone. There was also a steep fall in the mean CPP to 34.2 +/- 19.6 mm Hg compared with 96.4 +/- 13.8 mm Hg in the control group. White-matter water content anterior to the occlusion site was elevated to 81.9 +/- 3.7 gm/100 gm frozen weight in the fibrin group as compared to 70.7 +/- 2.2 gm/100 gm in controls. Posterior to the occlusion site, water

  7. Maxillary sinus carcinoma: Natural history and outcome

    International Nuclear Information System (INIS)

    To assess natural history, treatment outcome and pattern of relapse in patients with maxillary sinus carcinoma. A review was conducted of the medical records of all adult patients with maxillary sinus carcinoma, who were treated at King Faisal Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, between January 1990 and December 1999. A total of 60 patients were identified for analysis, 36 men and 24 women; the median age was 58-years (range 23-95). Major presenting symptoms were facial swelling 55%, facial pain 50%, and nasal obstruction 43.4%, with a median duration of 5-months (range 1-24). Histology was quamous cell carcinoma in 71.7% and adenoid cystic in 16.7%. They were restaged according to American Joint Committee on Cancer classification 1997 as II, III and IV in 1, 10 and 49. Thirty patients received treatment with curative intent (surgery in 4 patients, radiotherapy in 2, and combined modality in 24), 6 patients refused treatment and 24 were treated palliatively. With a median follow up of 50-months (range 2-128) in surviving patients treated with a curative intent, 12/30 failed locally, 4/30 in the regional neck nodes and 2/30 had systemic relapse. The actuarial 5-year overall survival (OS), relapse free survival (RFS) and local control rate (LC) were 55%, 39% and 51%. Treatment modality was the only significant prognostic factor for outcome, with 5 year OS, RFS and LC of 72%, 49% and 61%, for combined modality using surgery followed by radiotherapy compared to 0% for single approach (p=0.0003, p=0.0052 and p=0.0098). This study indicates that the majority of our patients presented with advanced disease, resulting in poor outcome to conventional treatment modalities. Efforts should be directed to minimize the delay in diagnosis at the primary care level. Combined modality treatment should be offered to all patients with locally advanced disease. New approaches such as neoadjuvant or concurrent chemoradiotherapy with or without surgery need to

    International Nuclear Information System (INIS)

    Objective: To assess the frequency of the lacrimal recess in the maxillary sinus (MS) in computed tomography (CT) of the paranasal sinuses. Methods: CT of the paranasal sinuses (CT PNS) done in a total of 78 patients. According to the discoveries, the MS were classified in two types: anterior or lateral. Results: 41 CT PNS of 41 patients of a total of 78 patients preselected were excluded. 37 CT of the paranasal sinuses from 37 patients, in a total of 68 maxillary sinuses were studied. In the 33 right maxillary sinuses, 10 lacrimal recesses were found, 9 from male patients. Eleven left maxillary sinuses with lacrimal recess were found from a total of 35 left maxillary sinuses. Conclusion: From the analysis of 68 MS, a frequency of 30.9% of lacrimal recesses in the maxillary sinuses in CT was observed

  9. Differentiation of mucosal disease from partial development of the paranasal sinuses in pediatric patients

    International Nuclear Information System (INIS)

    On magnetic resonance (MR) images of pediatric patients, sinus mucosal disease may have an appearance similar to that of the normal partially developed sinus, leading to an increase in the number of patients labeled as having incidental sinusitis. The paranasal sinuses were retrospectively evaluated in 27 infants and children aged 0-11 years undergoing brain MR imaging for indications both unrelated and related to sinus disease. The authors developed criteria for grading paranasal sinus development and mucosal disease. Incidental mucosal disease is not uncommon, occurring in 28% of patients aged 0-7 years. In children under 3 years of age, inflammatory mucosal thickening and marrow surrounding the partially developed sinus have a high signal on many MR sequences and may be confused. Recognition of the low-intensity peripheral cortical margin of the sinus and awareness of the stages of normal sinus development allow differentiation

    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.

  12. Map kinases in fungal pathogens.

    MAP kinases in eukaryotic cells are well known for transducing a variety of extracellular signals to regulate cell growth and differentiation. Recently, MAP kinases homologous to the yeast Fus3/Kss1 MAP kinases have been identified in several fungal pathogens and found to be important for appressorium formation, invasive hyphal growth, and fungal pathogenesis. This MAP kinase pathway also controls diverse growth or differentiation processes, including conidiation, conidial germination, and female fertility. MAP kinases homologous to yeast Slt2 and Hog1 have also been characterized in Candida albicans and Magnaporthe grisea. Mutants disrupted of the Slt2 homologues have weak cell walls, altered hyphal growth, and reduced virulence. The Hog1 homologues are dispensable for growth but are essential for regulating responses to hyperosmotic stress in C. albicans and M. grisea. Overall, recent studies have indicated that MAP kinase pathways may play important roles in regulating growth, differentiation, survival, and pathogenesis in fungal pathogens. PMID:11273677

    Digoxin, in a common clinical dose and at a low serum level, brought out severe manifestations of sinus node dysfunction in a patient who had previously undergone successful mitral valve replacement. This report presents the results of extensive clinical and electrophysiologic studies of this patient before and after a digoxin challenge. In the absence of cardiac glycoside, the only demonstrable abnormalities of sinus node function were mild resting sinus bradycardia and failure to respond to atropine administration. Responses to isoproterenol administration, programmed premature atrial stimulation, and overdrive pacing at several cycle lengths were normal. Following the administration of intravenous digoxin, 1.025 mg/24 hrs, the resting sinus cycle length increased and the response to overdrive pacing became markedly abnormal. The latter was followed by sinus pauses in excess of six seconds, even at relatively slow overdrive pacing rates. The electrophysiologic and clinical implications of these data are discussed. It is suggested that despite previous reports that digitalis preparations are relatively well tolerated by patients with sick sinus syndrome, caution should be used when administering these drugs to this group of patients.

    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

    The diagnosis of fungal laryngitis is often overlooked in immunocompetent patients because it is commonly considered a disease of the immunocompromised. Further confusion is caused by clinical and histological similarity to more common conditions like Leukoplakia. Demonstration of hyperkeratosis particularly if associated with intraepithelial neutrophils on biopsy should trigger a search for fungus using specialized stains. These patients usually present with hoarseness of voice. Pain is present inconsistently along with dysphagia and odynophagia. We present three cases of fungal laryngitis in immunocompetent patients out of which one underwent microlaryngeal surgery with excision biopsy. All these patients responded well with oral antifungal therapy.

    Aim: To analyse several reference structures using axial computed tomography (CT) imaging of the temporal bone, which may reflect pneumatization of the entire temporal bone by statistical correlation to the actual volume of the temporal bone measured using three-dimensional reconstruction. Materials and methods: One hundred and sixteen temporal bones were studied, comprising 48 with normal findings and 68 sides showing chronic otitis media or temporal bone fracture. After measuring the volume of temporal bone air cells by the volume rendering technique using three-dimensional reconstruction images, classification of temporal bone pneumatization was performed using various reference structures on axial images to determine whether significant differences in the volume of temporal bone air cells could be found between the groups. Results: When the sigmoid sinus at the level of the malleoincudal complex was used in the classification, there were statistically significant differences between the groups that correlated with the entire volume of the temporal bone. Grouping based on the labyrinth and the ascending carotid artery showed insignificant differences in volume. Furthermore, there was no significant correlation between the cross-sectional area of the antrum and the entire volume of the temporal bone. Conclusion: The degree of pneumatization of temporal bone can be estimated easily by the evaluation of the air cells around the sigmoid sinus on axial CT images.

    Functional Endoscopic Sinus Surgery (FESS) is a challenging procedure for otolaryngologists and is the main surgical approach for treating chronic sinusitis, to remove nasal polyps and open up passageways. To reach the source of the problem and to ultimately remove it, the surgeons must often remove several layers of cartilage and tissues. Often, the cartilage occludes or is within a few millimeters of critical anatomical structures such as nerves, arteries and ducts. To make FESS safer, surgeons use navigation systems that register a patient to his/her CT scan and track the position of the tools inside the patient. Current navigation systems, however, suffer from tracking errors greater than 1 mm, which is large when compared to the scale of the sinus cavities, and errors of this magnitude prevent from accurately overlaying virtual structures on the endoscope images. In this paper, we present a method to facilitate this task by 1) registering endoscopic images to CT data and 2) overlaying areas of interests on endoscope images to improve the safety of the procedure. First, our system uses structure from motion (SfM) to generate a small cloud of 3D points from a short video sequence. Then, it uses iterative closest point (ICP) algorithm to register the points to a 3D mesh that represents a section of a patients sinuses. The scale of the point cloud is approximated by measuring the magnitude of the endoscope's motion during the sequence. We have recorded several video sequences from five patients and, given a reasonable initial registration estimate, our results demonstrate an average registration error of 1.21 mm when the endoscope is viewing erectile tissues and an average registration error of 0.91 mm when the endoscope is viewing non-erectile tissues. Our implementation SfM + ICP can execute in less than 7 seconds and can use as few as 15 frames (0.5 second of video). Future work will involve clinical validation of our results and strengthening the robustness to

  3. Sinusitis and intracranial sepsis: the CT imaging and clinical presentation

    International Nuclear Information System (INIS)

    The CT imaging and clinical presentation in 14 children with coexistent intracranial sepsis and sinusitis were reviewed. A routine CT head scan (10-mm thick semi-axial slices through the cranium done before and after intravenous contrast medium administration) was found to be an inadequate initial investigation as the intracranial collection was missed in four patients and the abnormal sinuses not shown in six. In half the children the dagnosis of sinusitis was unsuspected at the time of admission. The dominant clinical features were fever, intense headache and facial swelling in early adolescent males. In this clinical setting we recommend: (1) The routine scan is extended through the frontal and ethmoidal sinuses and photographed at a window level and width showing both bone detail and air/soft tissue interfaces; (2) direct coronal projections are performed through the anterior cranial fossa if no collection is seen on the routine study; (3) an early repeat scan within 48 h if the initial study shows no intracranial pathology but the fronto-ethomoidal sinuses are abnormal and there is a high clinical supicion of intracranial sepsis; and (4) in the presence of intracranial sepsis the vault is viewed at bone window settings to exclude cranial osteomyelitis.

    The Sinus Iridum region is one of the important candidate landing areas for the future Chinese lunar robotic and human missions. Considering its flat topography, abundant geomorphic features and complex evolutionary history, this region shows great significance to both lunar science and landing exploration, including powered descent, surface trafficability and in-situ exploration. First, we use Lunar Reconnaissance Orbiter (LRO) Altimeter (LOLA) and Camera (LROC) data to characterize regional topographic and geomorphological features within Sinus Iridum, e.g., wrinkle ridges and sinuous rilles. Then, we deduce the iron and titanium content for the mare surface using the Clementine ultraviolet-visible (UVVIS) data and generate mineral absorption features using the Chandrayaan-1 Moon Mineralogy Mapper (M3) spectrometer data. Later, we date the mare surface using crater size-frequency distribution (CSFD) method. CSFD measurements show that this region has experienced four major lava infilling events with model ages ranging from 3.32 Ga to 2.50 Ga. The regional magmatic activities evolved from Imbrian-aged low-titanium to Eratosthenian-aged medium-titanium. The inner Sinus Iridum is mainly composed of pyroxene-rich basalts with olivine abundance increasing with time, while the surrounding highlands have a feldspar-dominated composition. In the northern wall of Sinus Iridum, some potential olivine-rich materials directly excavated from the lunar mantle are visible. The Sinus Iridum region is an ideal target for future landing exploration, we propose two candidate landing sites for the future Chinese robotic and human missions.

    Background Surgery of pituitary adenomas invading cavernous sinus has always been thought as a challenge due to the complex anatomical structures and high risk of complications. The purpose of this study was to evaluate endoscopic trarssphenoidal approach to pituitary adenomas invading cavernous sinus.Methods The clinical data of 22 patients who admitted to Xuanwu Hospital with pituitary adenomas invading cavernous sinus were analyzed retrospectively. All patients underwent endoscopic transsphenoidal surgery. To expose the surgical field sufficiently, the opening of sellar floor was exceeded the bone overlying the invaded cavernous sinus, and synthetic dura was used to repair and strengthen the sella floor for preventing the leak of cerebrospinal fluid.Results Among 22 patients, total resection was achieved in 14, subtotal resection in 5, and partial resection in 3; no patient underwent insufficient resection. Visual symptoms improved in 7 of 9 patients. In one patient diplopia disappeared.Headache was relieved to various extents in all patients. No serious complications were found. Patient's hospital stay ranged from 7 to 20 days.Conclusion These data suggest that the endoscopic transsphenoid approach is a safe, minimally invasive, and efficient surgical technique, which might be an important therapeutic strategy for the pituitary adenoms invading cavernous sinus.

Results Mean RSA and mean positive RSA were nearly double with FV, both at baseline and following oleic acid. At baseline, mean RSA = 18.6 msec with CV and 36.8 msec with FV (n = 10; p = 0.043; post oleic acid, mean RSA = 11.1 msec with CV and 21.8 msec with FV (n = 9, p = 0.028; at baseline, mean positive RSA = 20.8 msec with CV and 38.1 msec with FV (p = 0.047; post oleic acid, mean positive RSA = 13.2 msec with CV and 24.4 msec with FV (p = 0.026. Heart rate variability was also greater with FV. At baseline the coefficient of variation for heart rate was 2.2% during CV and 4.0% during FV. Following oleic acid the variation was 2.1 vs. 5.6% respectively. Conclusion These findings suggest FV enhances physiological entrainment between respiratory, brain stem and cardiac nonlinear oscillators, further supporting the concept that RSA itself reflects cardiorespiratory interaction. In addition, these results provide another mechanism whereby FV may be superior to conventional CV.

    Full Text Available Cerebral venous sinus thrombosis (CVT is a rare cerebrovascular disease with variable presentation. CVT rarely causes hydrocephalus. Communicating hydrocephalus due to CVT is extremely rare. We describe a patient of CVT presenting with chronic headache and communicating hydrocephalus. The patient was successfully treated with ventriculoperitoneal (VP shunt. A 40 year old man presented with moderate to severe headache since six months and progressive visual loss since two months. Head Computed tomogram showed mild hydrocephalus without obstruction. Lumbar puncture (LP demonstrated elevated pressure but was otherwise normal. Magnetic resonance venogram showed extensive CVT. Repeated CSF drainage and thecoperitoneal shunt did not relieve the severe headache hence a VP shunt was placed. Post shunt headache subsided with resolution of hydrocephalus. CVT can present as communicating hydrocephalus. Gradual reduction of intra-ventricular pressure by repeated LPs followed by VP shunt can safely treat hydrocephalus due to CVT.

    Slowly inactivating Na+ channels conducting "late" Na+ current (INa,late) contribute to ventricular arrhythmogenesis under pathological conditions. INa,late was also reported to play a role in chronic atrial fibrillation (AF). The objective of this study was to investigate INa,late in human right......, and lower in AF than in SR. In conclusion, We confirm for the first time a TTX-sensitive current (INa,late) in right atrial cardiomyocytes from SR and AF patients at room temperature, but not at physiological temperature. While our study provides evidence for the presence of INa,late in human atria...... atrial cardiomyocytes as a putative drug target for treatment of AF. To activate Na+ channels, cardiomyocytes from transgenic mice which exhibit INa,late (ΔKPQ), and right atrial cardiomyocytes from patients in sinus rhythm (SR) and AF were voltage clamped at room temperature by 250-ms long test pulses...

    Many species of fungi naturally produce light, a phenomenon known as bioluminescence, however, the fungal substrates used in the chemical reactions that produce light have not been reported. We identified the fungal compound luciferin 3-hydroxyhispidin, which is biosynthesized by oxidation of the precursor hispidin, a known fungal and plant secondary metabolite. The fungal luciferin does not share structural similarity with the other eight known luciferins. Furthermore, it was shown that 3-hydroxyhispidin leads to bioluminescence in extracts from four diverse genera of luminous fungi, thus suggesting a common biochemical mechanism for fungal bioluminescence.

Methods A case of hepatitis B virus with sinus bradycardia in our hospital was retrospectively analyzed. Results The patient was admitted for anorexia, liver area pain for 9 days. Then the jaundice and nausea gradually appeared. 5 days after admission, serious sinus bradycardia appeared. The sinus node function test showed that the patient's sinus node function was low in the basic situation. Because of chronic hepatitis B virus history, the patient was diagnosed as having the sinus bradycardia caused by hepatitis B virus. The hepatitis B virus was controlled after the patient was treated with liver protecting, jaundice reducing and antiviral drugs, and the symptom of sinus bradycardia was also relieved. In the end the patient recovered. Conclusion Hepatitis B virus with sinus bradycardia is uncommon clinically. A good understanding of pathogenesis and clinical features of the disease will help to reduce the rates of misdiagnosis and mistreatment.

  13. Anatomical variations of paranasal sinuses: what to inform the otolaryngologist?

    International Nuclear Information System (INIS)

    Anatomic variations of paranasal sinuses are common findings in daily practice. For a radiologist, to know these variations is necessary because of the pathological conditions related to them, and also because they are import for planning a functional endoscopic endonasal surgery, the procedure of choice for diagnosis, biopsy and treatment of various sinonasal diseases. To assure that this surgery is done safely, preventing iatrogenic injuries, it is essential that the surgeon has the mapping of these structures. Thus, a CT is indispensable for preoperative evaluation of paranasal sinuses. Since a general radiologist is expected to know these changes and their relationship to pathological conditions, a literature review and a iconographic essay were conducted with the aim of discussing the importance of major anatomic variations of paranasal sinuses.

    Sick sinus syndrome is a generalized abnormality of cardiac impulse formation that may be caused by extrinsic causes or by intrinsic disease of the sinus node making it unable to perform pace making function. It can be manifested for the first time in pregnancy. First case was diagnosed as sick sinus syndrome at 8 weeks of gestation having Mobitz type I heart block (Wenckebach block), and needed temporary pacemaker during caesarean section. Second case was diagnosed at 24 weeks of gestation having complete heart block and needed permanent pacemaker at 38 weeks of gestation due to exaggeration of the symptoms. Both the cases were dealt successfully by caesarean section under general anesthesia in close collaboration with cardiologists and anesthesiologists.

    Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy, SHML) is a rare, non-hereditary, benign histiocytic proliferative disorder, presenting as painless bilateral cervical lymphadenopathy, with systemic symptoms. Extra nodal manifestations have been reported in 28-43 % cases with rare ocular involvement. We report a case of a 57 year old female presenting with gradual progressive decrease of vision OU since 8 months associated with epistaxis. Fundus examination revealed established optic atrophy in right eye with features of chronic papilloedema in left eye suggestive of compressive lesion. CT of brain, paranasal sinuses confirmed the presence of homogenously enhancing mass in left ethmoid sinus, left sphenoid sinus extending into suprasellar region. The biopsy of this mass revealed extra nodal SHML with tissue sections being S100 and CD68 positive with emperipolesis noted. Here we describe this atypical ocular presentation of extra nodal SHML to highlight that this rare disease can manifest as an aggressive sight threatening entity, even in older age group.

    AIM: To study the effect of capsaicin on carotid sinus baroreceptor activity (CBA). METHODS: The functional curve of carotid baroreceptor (FCCB) was constructed and the functional parameters of carotid sinus baroreceptor were measured by recording sinus nerve afferent discharge in anesthetized rats with perfused isolated carotid sinus. RESULTS: Low-concentration of capsaicin (0.2μmol/L) had no significant effect on CBA, while perfusion of the isolated carotid sinus with middle-concentration of capsaicin (1μmol/L) could shift FCCB to the left and upward,with peak slope (PS) increased from (2.47%±0.14%)/mmHg to (2.88%±0.10%)/mmHg (P<0.05) and peak integral value of carotid sinus nerve discharge (PIV) enhanced from 211%±5% to 238%±6% (P<0.01). The threshold pressure (TP) and saturation pressure (SP) were significantly decreased from 68.0±1.1 to 62.7±1.0mmHg (P<0.01) and from 171.0±1.6 to 165.0±0.6 mmHg (P<0.01). By perfusing with high-concentration of capsaicin (5μmol/L), FCCB was shifted to the left and upward further and the changes of the functional parameters such as PS, TP, and SP were concentration-dependent. Pretreatment with ruthenium red (100μmol/L), an antagonist of vanilloid receptor subtype 1 (VR1), blocked the effect of capsaicin on CBA. Preperfusion with glibenclamide(20μmol/L), a KATP channel blocker, could eliminate the effect of capsaicin on CBA. CONCLUSION: Capsaicin exerts a facilitatory role on the isolated carotid baroreceptor in a concentration-dependent manner. The facilitatory action of capsaicin may be attributed to the opening of KATP channels mediated by VR1.

    International Nuclear Information System (INIS)

    The significance of mycotic concretions of 'metal density' in the diagnosis of aspergillosis of the paranasal sinuses has been analysed in 47 patients with this diagnosis. The incidence, types, radiological appearances and chemical composition of these very dense calcifications are discussed. Demonstration of these concretions, if metal foreign bodies and displaced dental fillings are excluded, are evidence for a mycosis of the paranasal sinuses. Absence of these dense structures does not exclude aspergillosis and was present in our clinical material in only 50% of cases. (orig.)

    Facial vein thrombophlebitis is an uncommon complication of sinusitis. In cases where periorbital swelling complicating sinusitis is diagnosed, clinical findings of swelling and erythema extending beyond the orbital region into the cheek should alert the physician about this unusual complication and the need for further contrast-enhanced imaging and venography. The radiologist must be particularly careful in the evaluation of vascular structures of the face and neck in these children. CT and MRI with contrast material and MR venography are studies that clearly demonstrate the vascular anatomy and possible complications. However, MR venography confirms flow abnormalities within the venous system with the advantage of avoiding radiation exposure to the pediatric patient. (orig.)

    Full Text Available A 70-year-old black woman presented with intermittent palpitations and dyspnea was found to be bradycardic with a normal sinus rhythm. She had instilled her topical timolol maleate approximately 30 minutes prior to each of these episodes. Topical timolol was discontinued and the conduction abnormality resolved. She was diagnosed as having intermittent sinus bradycardia with intermittent atrioventricular block, likely induced by topical beta-blocker therapy. Topical timolol maleate is an effective treatment for ocular hypertension, acting by reducing aqueous fluid production. However, it can induce systemic side effects and should be used with caution in patients with, or predisposed to, cardiac or respiratory depression.

    A 49-year-old male patient with a carcinoma of the right pyriform sinus had a whole-body bone scan and gamma camera based F-18 FDG-PET for staging. Tc-99m MDP bone scan depicted diffuse increased uptake in the left femur due to chronic osteomyelitis but no skelectal metastasis. F-18-FDG-PET revealed increased focal bone uptake and uptake in the draining sinus due to chronic osteomyelitis in addition to visualization of the right pyriform sinus carcinoma and right neck nodal uptake. Fluorine-18 fluorodeoxyglucose-positron emission tomography is significantly more accurate than the bone scan in pinpointing chronic osteomyelitis focus and draining soft tissue infection.

  15. Imaging of chronic osteomyelitis

    International Nuclear Information System (INIS)

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI.

    2016-01-01

    The aim of this retrospective study was to report preliminary outcomes of a modified technique for transcrestal sinus floor elevation with simultaneous implant placement. A total of 165 implants were placed in 110 patients using a modified Summers technique. During implant site preparation, after fracturing the sinus floor, a small perforation of the membrane was made using the first osteotome. After grafting with anorganic bovine bone mixed with venous blood, standard-length implants were inserted. The prosthetic phase occurred after 4 to 5 months. Patients were followed for at least 2 years after loading. During the follow-up, sinus condition was assessed by cone beam computed tomography. Periapical radiographs were taken to assess graft height and peri-implant bone levels. Three implants failed within 2 months of placement, yielding an overall implant survival of 98.2%. The mean follow-up was 38.3 months (range: 28 to 60 months) from placement. All other implants were stable and peri-implant soft tissues were healthy throughout the observation period. Peri-implant bone loss averaged 0.62 ± 0.26 mm after 1 year of function. No biologic or biomechanical complications occurred. No evidence of graft material dispersion into the sinus space was detected, except for two cases that resolved spontaneously. After 1 year of loading the graft height averaged 4.8 ± 1.3 mm above the sinus floor level. In the presence of sinus membrane perforation, the proposed modified osteotome technique may allow a predictable rehabilitation of the atrophic posterior maxilla by means of standard length implants without the occurrence of adverse events.

  18. Subseafloor basalts as fungal habitats

    2013-12-01

    The oceanic crust makes up the largest potential habitat for life on Earth, yet next to nothing is known about the abundance, diversity and ecology of its biosphere. Our understanding of the deep biosphere of subseafloor crust is, with a few exceptions, based on a fossil record. Surprisingly, a majority of the fossilized microorganisms have been interpreted or recently re-interpreted as remnants of fungi rather than prokaryotes. Even though this might be due to a bias in fossilization the presence of fungi in these settings can not be neglected. We have examined fossilized microorganisms in drilled basalt samples collected at the Emperor Seamounts in the Pacific Ocean. Synchrotron-radiation X-ray tomography microscopy (SRXTM) studies has revealed a complex morphology and internal structure that corresponds to characteristic fungal morphology. Chitin was detected in the fossilized hyphae, which is another strong argument in favour of a fungal interpretation. Chitin is absent in prokaryotes but a substantial constituent in fungal cell walls. The fungal colonies consist of both hyphae and yeast-like growth states as well as resting structures and possible fruit bodies, thus, the fungi exist in vital colonies in subseafloor basalts. The fungi have also been involved in extensive weathering of secondary mineralisations. In terrestrial environments fungi are known as an important geobiological agent that promotes mineral weathering and decomposition of organic matter, and they occur in vital symbiosis with other microorganisms. It is probable to assume that fungi would play a similar role in subseafloor basalts and have great impact on the ecology and on biogeochemical cycles in such environments.

Fuelled by molecular oxygen, these enzymes can act on dozens of molecules of different chemical nature, and with the help of redox mediators, their spectrum of oxidizable substrates is further pushed towards xenobiotic compounds (pesticides, industrial dyes, PAHs), biopolymers (lignin, starch, cellulose) and other complex molecules. In recent years, extraordinary e...

    Full Text Available A pseudo-epidemic of environmental fungi, most likely by Fusarium spp., leading to inappropriate investigations for disseminated systemic mycosis is described. Subtle diagnostic clues, including the specimens affected, the nature of the host response, and the type of fungal elements noted helped to determine the nature of contaminants. The potential pitfall can be avoided by the knowledge of pertinent disease biology, prompt consultation for infectious diseases, and investigations of the potential environmental sources followed by source control.

    Full Text Available 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 infection by taking a systems biological approach, i.e., by a comprehensive quantitative analysis of the non-linear and selective interactions of a large number of functionally diverse, and frequently multifunctional, sets of elements, e.g., genes, proteins, metabolites, which produce coherent and emergent behaviours in time and space. The recent advances in systems biology will now make it possible to uncover the structure and dynamics of molecular and cellular cause-effect relationships within these pathogenic interactions.We review current efforts to integrate omics and image-based data of host-pathogen interactions into network and spatio-temporal models. The modelling will help to elucidate pathogenicity mechanisms and to identify diagnostic biomarkers and potential drug targets for therapy and could thus pave the way for novel intervention strategies based on novel antifungal drugs and cell therapy.

However, NCBI integrates many types of biomolecular data from variety of sources and makes it available to the scientific community as interactive web resources as well as organized releases of bulk data. These tools are available to explore and compare fungal genomes. Searching all databases with Fungi [organism] at http://www.ncbi.nlm.nih.gov/ is the quickest way to find resources of interest with fungal entries. Some tools though are resources specific and can be indirectly accessed from a particular database in the Entrez system. These include graphical viewers and comparative analysis tools such as TaxPlot, TaxMap and UniGene DDD (found via UniGene Homepage). Gene and BioProject pages also serve as portals to external data such as community annotation websites, BioGrid and UniProt. There are many different ways of accessing genomic data at NCBI. Depending on the focus and goal of research projects or the level of interest, a user would select a particular route for accessing genomic databases and resources. This review article describes methods of accessing fungal genome data and provides examples that illustrate the use of analysis tools. PMID:22737589

  4. Chronic Cough in Otorhinolaryngologic Routine

    Directory of Open Access Journals (Sweden)

    Palheta Neto, Francisco Xavier

    2011-04-01

    Full Text Available Introduction: The chronic cough is sometimes manifested as an imprecise symptom, but of great importance for both the diagnosis and the prognosis. In an otorhinolaryngologic approach, several illnesses that can occur with it can be numbered, including 2 of the 3 main causes of chronic cough. Objective: To identify the main otorhinolaryngologic diseases showing the chronic cough as one of their manifestations. Method: A literature's revision was performed in several scientific articles, specialized books and consultation in Birene and Scielo databases. Literature's revision: cough production in the upper airways is usually associated with an inflammatory reaction by stimulating sensitive receptors of these areas or by mechanic stimulus. The main cause of the chronic cough in the otorhinolaryngology day-to-day is the post-nasal drip, gathering together by itself 02 of the most common diseases: rhinitis and sinusitis. Laryngitis as a result of gastroesophageal reflux (GER stands out in the index of chronic cough etiology, but it is not as severe as GER . Neoplasias are also somewhat frequent causes of cough, and the difficulty in diagnosing the cough cause is common in this disease group. Motility disorder, laryngeal irritation persistence, parasitic disease and injuries by inhalation of toxic products were also found as a cause of cough for longer than 03 months. Conclusion:Chronic cough is a frequent and important finding in otorhinolaryngology and cannot be underestimated, and a careful anamnesis is the best way to determine the etiology and perform a correct treatment for the patient's disease.

    Background Subcutaneous fungal infections are caused by penetration of the causative fungi into the subcutaneous layer and are usually localised. We present a series of eight cases with subcutaneous fungal cystic lesions masquerading as benign lesions. Materials and Methods A retrospective study was conducted on subcutaneous fungal infections seen between January 2007 to July 2014 in the Department of Pathology. Eight patients with biopsy proven subcutaneous fungal infection were included. We collected and analysed their demographic, clinical and histopathological details. Results Among eight patients, six were male and two were female. The mean age was 47 years (Range: 21-70). All the eight patients presented with non-tender cystic swelling. The size of the swellings varied from a minimum of 3x3 cm to maximum of 10x4 cm. Out of eight, hand was involved in three, forearm in one, elbow in two, leg in one and foot in one. On H&E staining, all the cases showed fibro collagenous cyst wall, lined by histiocytes, granulomatous reaction, foreign body type of giant cells with acute and chronic inflammatory infiltrate containing fungal elements. Six were identified as hyalohyphomycosis and two were identified as phaeohyphomycotic cysts based on pigmentation of hyphae. Conclusion Fungal infection should be suspected in all subcutaneous cystic lesions. Excised tissue should always be sent for culture and histopathology. PMID:26557537

  6. Phylogenetic distribution of fungal sterols.

    Directory of Open Access Journals (Sweden)

    John D Weete

    Full Text Available 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 Delta(5 sterols in the earliest diverging fungal species to ergosterol in later diverging fungi. There are, however, deviations from this pattern in certain clades. Sterols of the diverse zoosporic and zygosporic forms exhibit structural diversity with cholesterol and 24-ethyl -Delta(5 sterols in zoosporic taxa, and 24-methyl sterols in zygosporic fungi. For example, each of the three monophyletic lineages of zygosporic fungi has distinctive major sterols, ergosterol in Mucorales, 22-dihydroergosterol in Dimargaritales, Harpellales, and Kickxellales (DHK clade, and 24-methyl cholesterol in Entomophthorales. Other departures from ergosterol as the dominant sterol include: 24-ethyl cholesterol in Glomeromycota, 24-ethyl cholest-7-enol and 24-ethyl-cholesta-7,24(28-dienol in rust fungi, brassicasterol in Taphrinales and hypogeous pezizalean species, and cholesterol in Pneumocystis. CONCLUSIONS/SIGNIFICANCE: Five dominant end products of sterol biosynthesis (cholesterol, ergosterol, 24-methyl cholesterol, 24-ethyl cholesterol, brassicasterol, and intermediates in the formation of 24-ethyl cholesterol, are major sterols in 175 species of Fungi. Although most fungi in the most speciose clades have ergosterol as a major sterol, sterols are more varied than currently understood, and their distribution supports certain clades of Fungi in current fungal phylogenies. In addition to the intellectual importance of understanding evolution of sterol synthesis in fungi, there is practical importance because certain antifungal drugs (e.g., azoles target reactions in

  7. Management of chronic paronychia

    2014-01-01

    Full Text Available Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management.

    2011-05-01

    Sick sinus syndrome is caused by sinus node dysfunction that renders it unable to function as a pacemaker. Patients with sick sinus syndrome are often asymptomatic or have symptoms that are mild and nonspecific. Lidocaine (0.5 mg/kg) injection is used for reduction of pain associated with intravenous injection of propofol. Episodes of marked bradycardia with sinus arrest after prophylactic lidocaine injection are reported in a 69-y-old man with no apparent preoperative cardiac disease or electrocardiographic abnormality. Surgery was postponed, and he was later diagnosed with sick sinus syndrome.

    2002-04-01

    Full Text Available A 55 year old male patient was operated on for a massive and vascular acoustic neurinoma in a sitting position. The tumor was completely excised. Post-operatively, the patient developed irritability and clinical features suggestive of contralateral cavernous sinus thrombosis. CT scan showed air within the dural walls of the cavernous sinus on the side of surgery. However, there was no radiological evidence of cavernous sinus thrombosis on the contralateral side. Cavernous sinus thrombosis as a post-surgery complication has not been reported. Air within the dural confines of the cavernous sinus has also not been observed or radiologically recorded in the literature.

  10. CT-demonstration of adipose tissue of the sinus cavernosus

    International Nuclear Information System (INIS)

    Adipose bodies of the sinus cavernosus - the only genuine intracranial adipose tissue - can be demonstrated well by CT. They appear as polymorph well defined hypodense objects in unilateral or bilateral manifestation. Adipose bodies most frequently show a size between 4 and 9 mm and densities about -20 to -40 HE. Occasionally the adipose bodies directly lead into the adipose tissue of the orbit. (orig.)

    Fat density in the cavernous sinus on computed tomography (CT) is described in 6 out of 16 (37.5%) patients with Cushing disease. This finding may aid in making a specific diagnosis in patients with a pituitary mass. It was not seen in 30 random CT studies of the sella; however, supra seller fat was incidentally noted in the patient with acromegaly.

  12. Left ventricular hemodynamics in patients with sick sinus syndrome

    International Nuclear Information System (INIS)

    The left ventricular (LV) systolic and diastolic functions in 31 patients with sick sinus syndrome (types I and II) were analyzed using LV time activity curves obtained by a 99mTc-RBC cardiac pool scintigraphy-forward and backward multiple gated study (FBMG) and compared with those in controls. On A-V sequential pacing (rate, 70 bpm; A-V delay, 150 msec), LV-peak ejection rate (PER) and peak filling rate (PFR) were significantly decreased compared to those in normal controls. As pacing rate was increased, PFR decreased significantly in patients in whom PER was decreased. The etiology of disturbed LV systolic and diastolic functions in patients with sick sinus syndrome remains unknown. No patient had significant organic coronary artery disease or other cardiac disorder. On the other hand, the frequency of vasospastic angina was higher in this group than in the controls. We suspect that sick sinus syndrome and vasospastic angina probably share a common pathophysiology. In patients with sick sinus syndrome, LV systolic and diastolic functions are impaired at rest and during A-V sequential pacing. (author)

    2016-01-01

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

    2014-03-01

    The link between natural disasters and subsequent fungal infections in disaster-affected persons has been increasingly recognized. Fungal respiratory conditions associated with disasters include coccidioidomycosis, and fungi are among several organisms that can cause near-drowning pneumonia. Wound contamination with organic matter can lead to post-disaster skin and soft tissue fungal infections, notably mucormycosis. The role of climate change in the environmental growth, distribution, and dispersal mechanisms of pathogenic fungi is not fully understood; however, ongoing climate change could lead to increased disaster-associated fungal infections. Fungal infections are an often-overlooked clinical and public health issue, and increased awareness by health care providers, public health professionals, and community members regarding disaster-associated fungal infections is needed.

    The valves in the venous system are surrounded by a thinner but expandable vein section that forms a pocket region known as the sinus. The exact function of the sinus pocket for the venous valves is not fully understood. This is especially an issue for the bioprostheticvalve, since most of the prosthetic valves do not have a sinus pocket. To determine the impact of the sinus pocket on the flow dynamics to a prosthetic valve, an in-vitro experiment was setup at normal physiological flow conditions to simulate the flow inside a venous system. Two different valve designs were tested in glass tubes simulating the vein vessel with and without the sinus pocket profile using 2-D particle image velocimetry (PIV). Velocity measurements were made, and vorticity and flow shear were calculated. The results show that vortex structures near the valve leaflet tip were preserved better with the sinus present. The jet width at valve exit was found to be narrower with sinus than without sinus, and the effect was more significant with longer leaflet length. The results suggest that the sinus pocket alters the flow around the valve and functions as a flow regulator. For prosthetic valve without sinus, a shorter leaflet would provide similar effect of sinus and thus is more preferable.

    Full Text Available Pneumosinus dilatans is an extremely rare condition which is characterized by gross enlargementof the paranasal sinuses. The etiology is not identified. Pneumosinus dilatans refers to an aeratedsinus which is abnormally expanded. Anatomical variations of the paranasal sinuses and nasalcavity are important in sinus diseases. We are reporting one patient with pneumosinus dilatanswho attended Duzce medical faculty ENT department with severe headache. We considered asfrontonasal complex and septum deviation disease by the CT and endoscopic examinations, andtreated by functional endoscopic surgery and septoplasty surgery. Headache and nasalobstruction symptoms disappeared completely in the follow up period. Frontal sinus size isfollowed up by CT. Frontal sinus enlargement was seen with the preoperative paranasal CTwhich are taken consecutive years. Frontal sinus size reduction was evaluated 18 months aftersurgery with the control paranasal sinus CT examination.

    To determine the factors affecting reproducibility of sinus node recovery time, the effects of basic pacing rate, pacing duration, milliamperage, vagal and beta-adrenergic stimulation, and sinud node injury, as well as its instantaneous and daily reproducibility, were studied in 36 anesthetized dogs. Corrected sinus node recovery time (CSNRT) showed a mean variation of 9.8 plus or minus 0.4 msec at an atrial pacing rate of 200 beats/min and 29.8 plus or minus 8 msec at an atrial pacing rate of 140 beats/min (P smaller than 0.05). CSNRT increased progressively from 55.4 plus or minus 10 msec to 103.7 plus or minus 13 msec with increase in pacing rate from 140 beats/min to 200 beats/min. It was reproducible when atrial pacing was carried out for 1-5 min, although a wide variation (10-30 msec) was seen from 7-60 minutes (P smaller than 0.05). This measurement was reproducible on two consecutive days and was unaffected by changes in milliamperage. Vagal stimulation consistently prolonged the CSNRT while beta-adrenergic stimulation decreased it from 132.9 plus or minus 34.5 msec to 50.0 plus or minus 6.5 msec. Sinus node injury consistently prolonged CSNRT at all paced rates. In summary, CSNRT is reproducible only if the same pacing rate and duration are utilized. Since vagal stimulation and sinus node injury prolong this measurement while beta-adrenergic stimulation shortens it, an "abnormal" CSNRT should be assessed in terms of the possible influence of the autonomic nervous system as well as sinus node dysfunction per se.

  5. Chronic Rhinosinusitis in Patients with Cystic Fibrosis.

    Science.gov (United States)

    Hamilos, Daniel L

    2016-01-01

    Chronic rhinosinusitis (CRS) is highly prevalent in patients with cystic fibrosis (CF) and accounts for significant morbidity and contribution to CF lung disease. Mutations of the cystic fibrosis transmembrane regulator gene occur with increased prevalence in patients with CRS without CF, suggesting some contribution to CRS pathophysiology. Nasal polyps (NPs) occur with increased prevalence in patients with CF of all ages and have a more neutrophilic appearance with fewer eosinophils and increased submucosal glandular elements in comparison to NPs from patients without CF. Mainstays of medical treatment include isotonic saline irrigations and topical intranasal glucocorticoids, with some evidence that topical intranasal glucocorticoids reduce NP size. Although inhaled hypertonic saline (7%) has been widely studied as a mucolytic agent for CF lung disease, there are no reports of its use in CF CRS. Mucolytics have also not been studied as a treatment for CRS in CF, and most evidence does not support their use for CF lung disease. Nasally nebulized dornase alfa (recombinant human deoxyribonuclease) following sinus surgery shows promise for treatment. Other unproven therapies include addition of baby shampoo to isotonic saline to potentially thin mucus and help prevent biofilm formation. There are no data to support the use of low-dose oral macrolide antibiotics or the use of prophylactic oral antibiotics for CRS in patients with CF. However, there is some support for the use of topical antibiotics, including colistimethate sodium or tobramycin, administered as a sinus irrigation or antral lavage in patients following sinus surgery when susceptible bacteria are cultured. Key components of CF sinus surgical management include extensive surgery to ensure that the maxillary, frontal, sphenoid, and ethmoid sinuses are all widely opened with smoothing of bony overhangs to prevent mucus retention and bacterial recolonization, postoperative meticulous daily nasal irrigations

    Full Text Available Abstract Background We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinuses, especially the thickness of the anterior wall of the maxillary sinus (at the canine fossa. To the best of our knowledge, this is the first report on the thickness of the canine fossa. This study aimed to (a estimate different dimensions of the maxillary and frontal sinuses measured on computed tomography (CT of the head, (b define cut-off values for the normal upper and lower limits of the different measured structures, (c determine differences in age, side and gender, (d compare manually and automatically estimated maxillary sinuses volumes, and (e present incidental findings in the paranasal sinuses among the study patients. Methods Dimensions of 120 maxillary and frontal sinuses from head CTs were measured independently by two radiologists. Results The mean value of the maxillary sinus volume was 15.7 ± 5.3 cm3 and significantly larger in males than in females (P = 0.004. There was no statistically significant correlation between the volume of maxillary sinuses with age or side. The mean value of the bone thickness at the canine fossa was 1.1 ± 0.4 mm. The automatically estimated volume of the maxillary sinuses was 14-17% higher than the calculated volume. There was high interobserver agreement with regard to the different measurements performed in this study. Different types of incidental findings of the paranasal sinuses were found in 35% of the patients. Conclusion We presented different dimensions of the maxillary and frontal sinuses on CTs. We believe that our data are necessary for further development of a clinically

    2016-08-01

    The ability of countless representatives of the Kingdom Fungi to adapt to and proliferate in diverse environments is facilitated by regulation of their secretomes to respond to changes in environmental conditions and to mediate interactions with other organisms. Secretome changes often fulfill common functions of nutrient acquisition, facilitation of host/symbiont interactions, cell wall modification, and optimization of the enzyme suite to adapt to new environmental resources. In this review, we expand on our recent work on signaling and the secretome in the pathogenic fungus Cryptococcus neoformans to consider a range of selected examples of regulation of fungal secretomes. These examples include the impact of carbon source and aspects of the response to plant and animal hosts. Additionally, the influence of key protein kinases (e.g., Pka1, Snf1) and transcription factors (e.g., Rim101/PacC) is highlighted to illustrate some underlying regulatory factors influencing the secretome. Although there is a wealth of information about fungal secretomes from both experimentation and genome sequence mining, there are also major gaps in our knowledge about the complete composition of fungal secretomes and mechanisms of dynamic change. For example, a more comprehensive understanding of the composition and regulation of the secretome will require consideration of the emerging roles of unconventional secretion and extracellular vesicles in delivering proteins outside the cell. Overall, changes in the secretome are well documented in diverse fungi and the underlying mechanisms are currently under investigation; however, there remain unknown steps in the regulation of secretory pathways and gaps in understanding the regulation of unconventional secretion, which warrant further research.

    The immune mechanisms of defence against fungal infections are numerous, and range from protective mechanisms that were present early in evolution (innate immunity) to sophisticated adaptive mechanisms that are induced specifically during infection and disease (adaptive immunity). The first-line innate mechanism is the presence of physical barriers in the form of skin and mucous membranes, which is complemented by cell membranes, cellular receptors and humoral factors. There has been a debate about the relative contribution of humoral and cellular immunity to host defence against fungal infections. For a long time it was considered that cell-mediated immunity (CMI) was important, but humoral immunity had little or no role. However, it is accepted now that CMI is the main mechanism of defence, but that certain types of antibody response are protective. In general, Th1-type CMI is required for clearance of a fungal infection, while Th2 immunity usually results in susceptibility to infection. Aspergillosis, which is a disease caused by the fungus Aspergillus, has been the subject of many studies, including details of the immune response. Attempts to relate aspergillosis to some form of immunosuppression in animals, as is the case with humans, have not been successful to date. The defence against Aspergillus is based on recognition of the pathogen, a rapidly deployed and highly effective innate effector phase, and a delayed but robust adaptive effector phase. Candida albicans, part of the normal microbial flora associated with mucous surfaces, can be present as congenital candidiasis or as acquired defects of cell-mediated immunity. Resistance to this yeast is associated with Th1 CMI, whereas Th2 immunity is associated with susceptibility to systemic infection. Dermatophytes produce skin alterations in humans and other animals, and the essential role of the CMI response is to destroy the fungi and produce an immunoprotective status against re-infection.

    The examination and treatment of 66 patients with rhinosinusogenic cerebral arachnoiditis (RCA) were performed using otorhinolaryngological and neurological tests with special emphasis on pneumoencephalography to provide objective assessment of the brain layers and ventricles. It is shown that RCA occurs most frequently in subjects suffering from chronic purulent axillary sinusitis or recurrent polysinusitis. RCA manifestations depend on the duration of rhinosinusitis and its recurrence rate. RCA onset is usually not acute and takes place at the time of rhinosinusitis exacerbation. There are also mild frontal headaches, pathological changes in the coats of the anterior cranial fossa. The above abnormalities were most pronounced at the side of rhinosinusitis or most affected sinus. The treatment should be first of all oriented on elimination of maxillary infection in line with pathogenetic treatment of RCA. An individual approach to treatment policy is advocated.

    Conidiobolomycosis is a rare chronic subcutaneous mycosis of nose and paranasal sinuse predominately affects the middle age men in tropical countries. It is caused by a saprophytic fungus "Conodiobolus coronatus", which can survives in soils and dried vegetables for long period of time. C. coronatus belongs to the class Zygomycetes, order Entomophthorales. It is a fungus composed of thick- walled, short hyphae that grows at temperatures of 30 to 37 degrees C. Here we report a case of conidiobolomycosis in a 55- year- old farmer presented with a subcutaneous swelling over the left side of nose extending to left cheek. PMID:26753137

    Full Text Available Purpose: The aim of this study was to determine the prevalence and location of maxillary sinus septa with the help of dental volumetric tomography. Methods: 760 patients’ 1520 maxillary sinus were evaluated by dental volumetric tomography for detecting maxillary sinus septa. Maxillary sinus was divided into 3 zones (anterior, middle and posterior zones while location of the maxillary sinus septa. Results: 47 of maxillary sinus septa existed in the anterior zone (24.7%, 35 of them in the middle zone (18.4% and 108 of them in the posterior region (56.8%. Conclusion: The formation of the maxillary sinus septa was affected by the existence or lack of the teeth. Correct detection of the presence of maxillary sinus septa was important prior to sinus lifting and dental implant surgery. Dental volumetric tomographical evaluation of maxillary sinus septa was more useful for a correct diagnosis and treatment planning. [Cukurova Med J 2013; 38(3.000: 467-474

    Full Text Available Background: Sex identification of unknown individuals is important in forensic sciences. At times when only skull remains are found and other means of identification fails, radiographs of frontal sinus can be used for identification. Frontal sinus morphology is unique to individual and can be used effectively in person identification; whereas its use in determining sexual dimorphism is limited. Aim: To determine sexual dimorphism among Indians by evaluating frontal sinus pattern using postero-anterior radiograph. Materials and Methods: The right and left areas, maximum height and width of frontal sinus were determined in 300 digital postero-anterior view radiographs obtained from 150 males and 150 females aged between 18-30 years. The measurements were carried out by transferring the image to Adobe® Photoshop® CS3 extended. Comparison of values were done using student′s t-test and accuracy of sex determination was assessed through Logistic regression analysis. Results and Conclusions: One hundred and forty seven males and 142 females show presence of frontal sinus with seven individuals showing unilateral/bilateral absence of frontal sinuses. The mean values of the frontal sinus height, width and area are greater in males. Right frontal sinus is larger than the left sinus in both the sex. The mathematical model based on logistic regression analysis gives an average concordance index for sex determination of 64.6%. Thus, frontal sinus provides average accuracy in sex determination among Indian population. This may be due to its greater variation in morphology.

  17. Complementary role of MR imaging of ethmomaxillary sinus disease depicted at CT in cystic fibrosis

    International Nuclear Information System (INIS)

    To assess whether MR imaging can improve characterization of ethmomaxillary opacification diagnosed at CT in patients with cystic fibrosis (CF) in order to select patients that may benefit from functional endoscopic sinus surgery (FESS). Material and methods: Sixty-two CF patients (26 females and 36 males) aged 4-50 years (median 20 years) with ethmomaxillary sinus disease at CT underwent MR examination of the paranasal sinuses (coronal T1 and STIR sequences). FESS had been performed in 28 of the patients prior to this study. MR signal intensities were interpreted as mucosal thickening or infectious material, according to a previous study. Results: Three major maxillary sinus MR patterns could be distinguished: Air-filled, oval-shaped pus-filled, and streaky-shaped pus-filled sinus lumen. For air-filled maxillary sinuses with mucosal thickening, CT and MR imaging were diagnostically equivalent. Where CT showed homogeneous opacification of the maxillary sinuses, MR imaging differentiated between thickened mucosa and pus-filled areas. Patients who had undergone FESS most commonly had air-filled or streaky-shaped pus-filled maxillary sinus lumen. In non-operated patients oval-shaped pus-filled sinus lumen was most common and could occur without ethmoid disease. Conclusion: MR imaging of the paranasal sinuses can differentiate between infectious material and thickened mucosa and should be used to select CF patients with pus-filled areas that can be eradicated with FESS

    To evaluate the relative diagnostic accuracy of panoramic radiography and Water's projection in maxillary sinus inflammatory diseases by comparing the radiodensities of the images with those of CT. Panoramic radiographs, Waters' projection, and CT images from 55 subjects (110 sinuses) were included in this retrospective study. The radiodensity of each maxillary sinus in panoramic radiography was recorded separately as upper and lower divided horizontally by hard palate. In Waters' projection, the overall sinus radiodensity was recorded. The CT images were considered as gold standard. In panoramic radiography, 83 sinuses had same upper and lower radiodensity and 72 of these were consistent with those of CT, 26 sinuses had different upper and lower radiodensity and 15 of these, upper radiodensity was consistent with CT, the remaining 11, lower radiodensity was consistent with CT. One sinus had upper radiolucency with lower radiopacity and both were consistent with those of CT. Altogether 73 (66.4%) among 110 sinuses in panoramic radiography showed full agreement with CT, 26 (23.6%) showed partial agreement with CT. 9 sinuses had no lower image under the hard palate in panoramic radiography due to the smaller size of sinus. In Waters' projection, the radiodensity of 105 sinuses (95.5%) were consistent with that of CT. The panoramic radiography showed 90.0% of the sinus conditions fully or partially which may appear less accurate than that of Water's view (95.5%) but with more detailed information of the inferior part of sinuses.

    Many forests are affected by chronic acid deposition, which can lower soil pH and limit the availability of nutrients such as phosphorus (P), but the response of mycorrhizal fungi to changes in soil pH and P availability and how this affects tree acquisition of nutrients is not well understood. Here, we describe an ecosystem-level manipulation in 72 plots, which increased pH and/or P availability across six forests in Ohio, USA. Two years after treatment initiation, mycorrhizal fungi on roots were examined with molecular techniques, including 454-pyrosequencing. Elevating pH significantly increased arbuscular mycorrhizal (AM) fungal colonization and total fungal biomass, and affected community structure of AM and ectomycorrhizal (EcM) fungi, suggesting that raising soil pH altered both mycorrhizal fungal communities and fungal growth. AM fungal taxa were generally negatively correlated with recalcitrant P pools and soil enzyme activity, whereas EcM fungal taxa displayed variable responses, suggesting that these groups respond differently to P availability. Additionally, the production of extracellular phosphatase enzymes in soil decreased under elevated pH, suggesting a shift in functional activity of soil microbes with pH alteration. Thus, our findings suggest that elevating pH increased soil P availability, which may partly underlie the mycorrhizal fungal responses we observed. PMID:26850158
