Objective was to report the allergic fungal sinusitis (AFS) in children in Saudi Arabia and to review the experience of King Abdul-Aziz University Hospital in diagnosis and management of AFS in children. Hospital charts of 45 children reviewed retrospectively. Clinical presentation, radiological and operative findings, management and outcomes studied. Only 25 patients had >-4 diagnostic criteria, treated endoscopically between January 2000 and December 2005 and followed at least 2 years in KAUH, Riyadh, Kingdom of Saudi Arabia. Twenty-five patients had at least 4 criteria for AFS> All patients underwent functional endoscopic sinus surgery (FESS) with high recurrence rate 44%. Twenty-eight percent needed revision surgery even with medical treatment post operatively. Moreover, no other complications were reported in this study. Aspergillus spp is the most common fungal type in our review. Allergic fungal sinusitis in children is underestimated and understudied associated with poor outcome and high recurrence because of difficulty in management. Therefore, the most effective approach of AFS management in children is to have a high index of suspicion, adequate, preoperative evaluation, medical preparation preoperatively, meticulous surgery, medical management, postoperative including topical and systemic corticosteroids and close clinical follow-up with endoscopically guided debridement.

Objective: To evaluate CT characteristics of fungal ball in paranasal sinus caused by different fungi and to enhance differential diagnosis. Methods: CT results and clinical data of 74 patients with fungal ball arising from the paranasal sinuses proved by histopathology from 2007 to 2009 were analyzed retrospectively. The CT characteristics of fungal ball in paranasal sinus caused by different fungi were compared using χ 2 test with P<0.05 considered statistically significant. Results: Among 74 mycotic pathogenic agents,aspergillus was found in 58 cases (including 36 cases with aspergillus flavus, 15 cases with aspergillus fumigatus and 7 with aspergillus versicolor), the others including 5 cases with penicillium, 6 cases with schizophyllum commune, and 5 cases with scedosporium apiospermum. There were significant differences in the number of sinus involved (single sinus involvement was seen in 29 cases caused by aspergillus group and 2 cases caused by non-aspergillus-group, respectively, with χ 2 =7.245, P=0.007), the incidence of fungus ball in ethmoid sinus [39.7% (23/58) of cases caused by aspergillus group and 81.3% (13/16) of cases caused by non-aspergillus-group, respectively, with χ2=8.685, P=0.003] and calcification (40 of 58 cases caused by aspergillus group and 5 of 16 cases caused by non-aspergillus-group, respectively, with χ 2 =7.485, P=0.006), the location of calcification (26 of 40 cases with central calcification and 14 of 40 cases with peripheral calcification in cases caused by aspergillus group, while all of 5 cases caused by non-aspergillus-group with peripheral calcification, χ 2 =7.697, P=0.006). However, there was no significant difference in the incidence of bilateral lesions (χ 2 =1.002, P=0.317), maxillary sinus involvement (χ 2 =0.020, P=0.888), sphenoidal sinus involvement (χ 2 =0.704, P=0.401), frontal sinus involvement (χ 2 =0.126, P=0.723), bony sclerosis (χ 2 =2.024, P=0.155), lamellar calcification (χ 2 =2.045, P=0

To investigate aerob-anaerob microorganisms growth in maxillary and ethmoid sinuses by evaluating aspiration materials from patients with chronic sinusitis. The study was performed prospectively, and there were 31 patients (23 men, 8 women; mean age, 31.4+/-14.15, between 18-65 years) who had endoscopic sinus surgery because of chronic sinusitis. During the operation, when the maxillary sinus ostium and ethmoid sinus were opened, readily aspirated materials from sinuses were evaluated regarding aerob and anaerob bacteria. Nose and throat swap samples were collected preoperatively to determine the upper respiratory tract flora and also to understand the relationship between the flora and the microorganisms aspirated from sinuses. Total aerob bacteria count, which was isolated from preoperative nasal swab cultures, was 36, and aerob-anaerob bacteria count that included cultures taken from maxillary and ethmoid sinuses during the functional endoscopic sinus surgery was 42. For each 2 samples, the most common isolated aerob bacteria were coagulase (-) staphylococci. Microorganisms were isolated in 87.0% of 27 patients, in which cultures taken from maxillary and ethmoid sinuses during the functional endoscopic sinus surgery were included. It is determined that the isolated aerob bacteria rate was 90.4%, and the isolated anaerob bacteria rate was 14.2%. All of the 6 samples in which anaerob bacteria isolated were all maxillary sinus aspiration materials. Microorganisms that isolated from the nose and the sinuses were similar with the rate of 25.8%, and microorganisms that isolated from the throat cultures and sinuses were similar with the rate of 22.5%. This study reveals the aerob and anaerob microbiology of the maxillary and ethmoid sinuses so the treatment of chronic sinusitis will be easier.

Mycotic infection of paranasal sinus could be the etiological factor of chronic sinusitis. The increase in number of fungal sinusitis cases have been reported recently among nonimmunocompromised patient after endodontic treatment of maxillary teeth. Nonspecific clinical signs and incorrect radiologic pictures interpretation as well as loss of therapeutic standards seems to be the cause of false negative diagnosis and difficulties in treatment of fungal sinusitis. Clinical and radiological picture of maxillary sinus aspergillosis was described in this paper. In the period of 2006-2009 in the Department of Maxillo-Facial Surgery 19 patient with fungal maxillary sinusitis was treated. The endodontic treatment of maxillary teeth of the related side was performed previously in 80% examined cases. In 2 cases there were immunocompromised patients with immunosuppressive treatment. In 16 cases patients were referred to our Department due to metallic foreign body of the maxillary sinus. Routine diagnostic radiological imaging was performed in each case: paranasal sinus view--Water's view and panoramic radiograph (orthopantomograph). In 4 cases imaging was extended with computer tomography (CT) visualization. The surgical treatment was performed in each case. The final diagnosis was puted on histopathological examination and fungal culture. In 16 cases of analysed group histopathological examination and fungal culture revealed aspergilosis. In 2 cases fungal culture was negative, but histopathology slices confirm presence of hyphae of Aspergillus. In 1 case the root canal sealer was found in the maxillary sinus. In none case invasive form of aspergillosis was confirmed. In all cases Water's view of paranasal sinuses and ortopantomograph showed partially or totally clouded sinus with well-defined, single or multifocal radiopaque object similar to metallic foreign body. Characteristic finding in CT imaging was well-defined radiodence concretions that have been attributed to

Full Text Available Introduction: Clinical case report of rhinosporidiosis, a rare and chronic granulomatous disease, caused by Rhinosporidium seeberi. Objective: To include this disease in the differential diagnoses of polypoid lesions of the nasal mass. Report: A male patient from the North of Brazil evolved a three-year papilomatous polypoid lesion of the left nasal cavity. He was submitted to sinusectomy with resection of the entire lesion, located in ethmoid bulla and uncinated process. Inverted papilloma or fungal sinusitis were differential diagnoses. The histopathological examination revealed a strong infestation by numerous fungal structures with sporangia shape full of sporangiospores. The microorganisms were positive for colorations of Grocott, PAS and Mayer's Mucicarmin; opposite from Coccidioides immitis, which presents no contrast by the mucicarmin. We didn't choose complimentary treatment and after one year of follow-up he presents with no sign of recurrence. Final Comments: Rhinosporidiosis must be considered to be a nasal polypoid lesion differential diagnosis. In the intranasal lesions diagnosis we should keep in mind the patient's origin. The anatomopathological study is mandatory to set the diagnosis. In the rhinosporidiosis, the surgical exeresis can be a curative treatment.

We present a case of maxillary sinusitis caused by Schizophyllum commune, in a 50-year-old female. The patient presented with nasal obstruction, purulent nasal discharge from right side of the nose, cough, headache, and sneezing. Computed tomography revealed extensive opacity of the right maxillary sinus as well as erosion of the nasal wall and maxillary bone. Functional endoscopic sinus surgery was done, and fungal debris present on right side of the maxillary sinus was removed and sent to laboratory. Potassium hydroxide (KOH) examination of the nasal discharge showed hyaline, septate hyphae. Primary isolation on Sabouraud's dextrose agar (SDA) yielded a white woolly mould. Banana peel culture after 8 weeks showed macroscopically visible fan-shaped fruiting bodies. Lactophenol cotton blue (LPCB) mount of the same revealed hyaline septate hyphae, often with clamp connections. Identification was confirmed by the presence of clamp connections formed on the hyphae and by vegetative compatibility with known isolates.

Acute invasive fungal sinusitis (AIFS) is a frequently fatal infection for which extensive and debilitating surgical debridement is a mainstay of therapy. Resulting defects are often composite in nature, mandating free tissue-transfer reconstruction. Outcomes data for free flap reconstruction are limited. The purpose of this study was to examine surgical outcomes and survival in patients undergoing free flap transfer following invasive fungal sinusitis. Retrospective case series. Between 1995 and 2015, patients undergoing operative debridement for AIFS were identified. Surgical records were used to identify survivors of acute infection who subsequently underwent free flap reconstructive surgery. Patient demographics, cause of immune compromise, defect description, flap type, perioperative complications, indications for revision surgery, functional outcomes, and long-term survival were reviewed. Forty-four patients were treated for AIFS, of those, 30 (68%) survived acute infection. Ten patients underwent maxillectomy, six with orbital exenteration, and were designated candidates for reconstruction. Eight patients underwent reconstruction. Median time from debridement to reconstruction was 67.5 days. Flap types included latissimus dorsi, scapula, anterolateral thigh, rectus, radial forearm, and fibula. Median follow-up was 7.7 months. No perioperative complications were encountered, and all subjects remained disease-free, able to speak and eat normally without prosthetic supplementation. Seven patients (87%) are currently alive. Reconstruction of defects left by invasive fungal sinusitis using free-tissue transfer resulted in successful flap survival, with no disease recurrence for all defects and flap types reviewed. Survivors of AIFS are able to tolerate midface reconstruction, with favorable functional outcomes and survival rates. 4.

Full Text Available   Abstract   Background: Invasive fungal infection is an opportunistic infection caused commonly   by mucoraccae and aspergillus. It mostly occurs in patients with underlying disease.   Since it has a high mortality and morbidity rate, considering a treatment strategy seems   necessary.   Objective: Since there has not been a clear protocol for treating these patients, we decided   to establish a protocol for fungal infection of sinus and anterior skull base management.   Methods: This retrospective and descriptive case study series included 30 patients.   After confirming the pathogen, the authors came to a proper protocol for treatment which   is mentioned later.   Results: The site involvement included nose and orbital cavity (53.3%, anterior skull   base and brain in conjunction with sinonasal (36.6% and simple nasal cavity involvement   (10%. 86.6% of the patients had underlying diseases. 56.6% of patients had diabetes   as a single underlying disease, while 13.3% had both diabetes and renal failure in   combination. Acute lymphocytic leukemia was present in 6.6%, renal failure in 3.3%, lupus   in 3.3% and chronic lymphocytic leukemia in 3.3% of patients. Mortality rate was   40%. We categorized the patients into 3 groups: only sinonasal, sinonasal and orbit, and   associated anterior skull base and brain involvement.   Conclusion: Early diagnosis is an important factor in improving survival. Anterior   skull base and brain involvement has a very poor prognosis.

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

We investigated the types and numbers of inflammatory cells that infiltrated the ethmoid sinus mucosa in cases of chronic sinusitis in order to identify any associations with nasal polyp size and the grade of ethmoid sinus opacification on computer tomography images. The subjects were patients with chronic sinusitis who underwent endoscopic sinus surgery. Seventeen subjects also had bronchial asthma as a complication (six with aspirin-induced asthma, 11 with another form of asthma) and 24 did not have bronchial asthma as a complication (16 with allergic rhinitis, 8 with chronic sinusitis alone). The nasal polyps in the patients with bronchial asthma were significantly larger than those in the patients without bronchial asthma. Investigation of the numbers of infiltrating inflammatory cells according to polyp size revealed significantly more eosinophils as polyp size increased. In addition, infiltration of significantly more mast cells was observed when the polyps were large. Assessment of the grade of opacification of the ethmoid sinuses on computer tomography images showed a significantly higher grade of opacification in the patients with bronchial asthma than in the patients without bronchial asthma. Comparisons between the grade of opacification of the ethmoid sinuses and the number of infiltrating inflammatory cells revealed significantly more infiltrating eosinophils and mast cells in the patients with intense ethmoid sinus opacification. The above findings suggest that eosinophils and mast cells play a major role in forming the persistent inflammation of the sinus mucosa and nasal polyp tissue of patients with chronic sinusitis complicated by bronchial asthma.

Full Text Available BACKGROUND Allergic Fungal Sinusitis (AFS is a noninvasive type of fungal sinusitis, clinically and pathologically a unique entity of chronic rhinosinusitis. The aetiology, pathogenesis, and treatment of AFS are subject to controversy. In spite of aggressive endoscopic surgery, pre- and postoperative steroids and immunotherapy recurrence rates are high. Many additions are made to its original description and management since its early description in 1980. The aim of the present paper was to evaluate clinically. The response to high-dose itraconazole before endoscopic sinus surgery and in refractory postoperative patients. Related literature was reviewed in the light of the present study. MATERIALS AND METHODS A 2 year prospective study conducted on 68 AFS patients divided into two groups to clinically evaluate the results after using oral itraconazole preoperatively in one group and in refractory postoperative period in another. RESULTS The mean age of patients with typical AFS was 36±3.9 years. Patients with AFS with an average follow up of 21 months were included. Recurrence was 6/34 (17.64% in itraconazole group and revision FESS done in 3/34 (08.82%. Recurrence in patients without itraconazole was 16/34 (47.05% and refractory to conventional treatment, but responded to itraconazole in 14/16 (87.50%. Revision surgery required in 2/16 (12.50% after starting oral itraconazole. No side effects or reactions were observed in a total of 7920 doses administered. CONCLUSION Itraconazole is well tolerated by patients and effective in shrinking the polyposis preoperatively with low recurrence. Postoperative refractory AFS is amenable in (87.50% of patients avoiding repeat FESS. Overall, low recurrence rate and minimizing revision surgery when compared to patients treated without itraconazole was evident in the study.

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

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

International Nuclear Information System (INIS)

Zinreich, S.J.; Kennedy, D.W.; Rosenbaum, A.E.; Kumar, A.J.; Stammberger, H.

1986-01-01

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

Full Text Available 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.

SUMMARY Humans with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), a T cell–driven autoimmune disease caused by impaired central tolerance, are susceptible to developing chronic fungal infection and esophageal squamous cell carcinoma (ESCC). However, the relationship between autoreactive T cells and chronic fungal infection in ESCC development remains unclear. We find that kinase-dead Ikkα knockin mice develop phenotypes reminiscent of APECED, including impaired central tolerance, autoreactive T cells, chronic fungal infection, and ESCCs expressing specific human ESCC markers. Using this model, we investigated the potential link between ESCC and fungal infection. Autoreactive CD4 T cells permit fungal infection and incite tissue injury and inflammation. Antifungal treatment or depletion of autoreactive CD4 T cells rescues, whereas oral fungal administration promotes, ESCC development. Inhibition of inflammation or EGFR activity decreases fungal burden. Importantly, fungal infection is highly associated with ESCCs in non-autoimmune human patients. Therefore, autoreactive T cells and chronic fungal infection, fostered by inflammation and epithelial injury, promote ESCC development. PMID:28407484

We reviewed all journal articles relevant to endoscopic medial maxillectomy in patients with recalcitrant chronic maxillary sinusitis in order to present all indications, the underlying pathophysiology and the developed surgical techniques. Despite the high success rate of middle meatal antrostomy, cases with persistent maxillary sinus disease exist and often need a more extended endoscopic procedure for the better control of the disease. Such surgical option uses gravity for better sinus drainage and offers better saline irrigation, local application of medications and follow-up inspection. An endoscopic medial maxillectomy and its modified forms offer a wider surgical field and access to all 'difficult' areas of the maxillary sinus. Patients with previous limited endoscopic sinus surgery or extended open surgery, cystic fibrosis, extensive mucoceles, allergic fungal sinusitis, odontogenic infections, foreign bodies and so on may suffer from recurrent disease requiring an endoscopic medial maxillectomy. Depending on the disease, various modifications of the procedure can be performed preserving the anterior buttress, nasolacrimal duct and inferior turbinate if possible.

Sinonasal Fungal Infections and Complications: A Pictorial Review

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.

Surgical treatment of chronic sacrococcygeal pilonidal sinus. Open method versus primary closure

International Nuclear Information System (INIS)

Kareem, Tayeb S.

2006-01-01

Objective was to study the comparison between the primary closure and open technique after excision of chronic sacrococcygeal pilonidal sinus. A randomized study was designed and 77 patients with chronic sacrococcygeal pilonidal sinus were included in this study. This study took place in Rizgary Teaching Hospital, Erbil, Kurdistan, Iraq, from January 1997 to August 2003. The patients were separated into 2 groups; Group A (37 patients) were treated by open method (excision and healing by secondary intention) and Group B (40 patients) for whom primary midline suturing was performed after excision of the pilonidal sinus. The follow up ranged from 1.5-5.5 years (mean 4.16) was through outpatient visits. The Student t test was applied for statistical analysis for the operating time, hospital-stay, time off from work and wound healing time; and the results show extremely significant differences between the 2 groups (p<0.0001). The statistical analysis of the total number of postoperative complications of both techniques showed a significant difference (p=0.0401), while the differences were insignificant for each complication when analyzed separately. Excision and primary closure for chronic sacrococcygeal pilonidal sinus is superior to excision and healing by secondary intention. We believe that primary midline suturing is a useful method for management of chronic sacrococcygeal pilonidal sinus. (author)

Chronic Maxillary Sinusitis Associated with an Unusual Foreign Body: A Case Report

Yunus Feyyat Şahin

2012-01-01

Full Text Available Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical removal of the foreign body either endoscopically or with a combined approach, with Caldwell-Luc procedure if endoscopic approach is inadequate for visualisation. In this case, we present a 24-year-old male patient with unilateral chronic maxillary sinusitis due to a wooden toothpick in left maxillary sinus. The patient had a history of upper second premolar tooth extraction. CT scan revealed sinus opacification with presence of a foreign body in left maxillary sinus extending from the floor of the sinus to the orbital base. The foreign body, a wooden toothpick, was removed with Caldwell-Luc procedure since it was impossible to remove the toothpick endoscopically. There was no obvious oroantral fistula in the time of surgery, but the position of the toothpick made us to think that it was inserted through a previously healed fistula, willingly or accidentally.

Chronic cheek ulcer caused by odontogenic cutaneous sinus tract

Odontogenic cutaneous sinus tracts are often misdiagnosed, and they lead to facial wounds and scarring. Therefore, we must be aware of the possibility of this condition. A dental origin must be considered for chronic ulcers involving the cheek, chin and submental areas. The clinical course of this patient suggests two important clinical issues for prompt diagnosis. First, physical examination, including palpation and probing, are helpful for exploration of sinus tracts. Second, computed tomography is useful to detect the sinus tract and affected teeth. Computed tomography provides radiographic evidence of the relationship between the tooth and cutaneous region, and it may be superior to radiography.

Chapter 8: Invasive fungal rhinosinusitis.

Duggal, Praveen; Wise, Sarah K

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.

Tuberculous sacroiliitis with abscess accounts for approximately 50 % of all sacroiliac joint tuberculosis cases. Tuberculous abscesses spread into the sacroiliac joint capsule, subcutaneous tissue, and the skin, and finally becomes a skin sinus. As there are no previous reports about sacroiliac joint tuberculosis with a chronic sinus, we evaluated its clinical characteristics and management by negative pressure wound therapy. A retrospective analysis of 12 patients with sacroiliac joint tuberculosis with chronic sinuses treated between January 2005 and January 2010 was conducted. Patients were treated with negative pressure wound therapy (NPWT). Treatment was divided into three phases: control phase, standard dressing changes daily for 4 weeks; interphase washout period, dressing changes every 3 days for 1 week; and intervention phase, no dressing changes until minimal sinus tract drainage (sacroiliac joint tuberculosis with a chronic sinus can be difficult. NPWT provides better healing of sacroiliac joint tuberculosis with a chronic sinus than standard dressing changes.

In the period 1983 to 1985, 66 patients presented to six Japanese university hospitals with squamous cell carcinoma of the maxillary sinus. Using self-administered questionnaires, a case-control study was conducted to examine history of nasal diseases, occupational exposures, and other possible risk factors for this disease. For each patient, two controls were selected from the general population, matched to the patient by sex, age (+/- 5 years), and district of residence. A history of chronic sinusitis was associated with a 2.3-fold increase in risk (p = 0.05). A high relative risk was also observed in males with an occupational history of woodworking or joinery, particularly when these jobs involved sanding or lathing practices (RR = 7.5, p = 0.02). No association between cigarette smoking and maxillary sinus cancer was observed in this study and no evidence was found that indoor air pollution in the home is involved in cancer development.

Nasal nitric oxide in unilateral sinus disease.

Full Text Available Unilateral sinus disease (USD can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19, chronic rhinosinusitis (CRS without nasal polyps (n = 13, CRS with nasal polyps (n = 12 and sinonasal mass lesions (n = 22. nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0% and specificity (87.2% for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

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 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.

2005-01-01

During this randomized, double blind study versus placebo efficacy of 3 month treatment of patients with chronic sinusitis was assessed. Main efficacy criterion was defined as the change in computed tomography of paranasal sinuses, measured in V. Lund scale. In fenspiride group, overall score changed from 8.54 to 7.57 points (0.97 points i.e. 11.4% decrease, p=0.008), while in placebo group no statistically significant change was observed (change from 9.25 to 9.27 points--0.02 points i.e. 0.2% increase). Percentage of patients who experienced worsening (defined as at least 1 point increase between the beginning and the end of the study) in the placebo group was twice as big as in the fenspiride group (35.4% and 15.2% respectively; p=0.025). Clinical symptoms of chronic sinusitis--sneezing, itchy nose and purulent character of sputum--were decreasing in the fenspiride group significantly more than in the placebo group. Data from previous studies demonstrated beneficial effect of fenspiride treatment of patients with chronic sinusitis. During this study fenspiride treatment was proved to be relatively effective in terms of computed tomography results, and well tolerated during three month therapy.

Full Text Available Abstract Background: Fungal spores are present in large amounts in the nature which may cause diseases in the susceptible individuals. Fungal rhinosinusitis has been increased during recent decades. This study aims to investigate fungal rhinosinusitis in the patients with chronic needing endoscopic sinus surgery aims and to determine the sensitivity of the isolates to rhin sinusitis antifungal agents. Materials and Methods: In cross sectional study, specimens were obtained in sterile plates containing normal saline. from the suspected cases of chronic rhinosinusitis who had undergone endoscopic sinus surgery. Microscopic experiments and Cultures were done in Sabouraud Dextrose Agar medium. Minimum inhibitory concentration (MIC of the growth of fungi for seven antifungal agents against the isolates was determined using E-Test. Results: In total, specimens from 102 immunocompetent patients were examined. Nine positive specimens were presented, consisting of 3 for Aspergillus fumigatus, 3 for Penicillium, 2 for Aspergillus flavus and 1 for Alternaria. The mean age of the patients was 38 years, with 59 males and 43 females. The isolates were most sensitive to the voriconazole and amphotericin B. Conclusion: Since the prevalence of fungal rhinosinusitis is low, unfortunately, the clinicians are not attentive enough to the condition, and they initiate antifungal therapy if the patients are not responsive to antibiotics. Early diagnosis and suitable treatment can help more efficient management of patients.

We assessed the effects of pacing-induced chronic atrial fibrillation (AF) on sinus node function, intra-atrial conduction, and atrial refractoriness. In 15 mongrel dogs (20 to 30 kg), AV nodal block was produced by radiofrequency catheter ablation, and a ventricular-inhibited (VVI) pacemaker (Minix 8330, Medtronic) was implanted and programmed to pace at 80 pulses per minute. In 11 of these dogs, right atrial endocardial pacing leads were connected to a pulse generator (Itrel 7432, Medtronic) and set at a rate of 20 Hz to induce AF. Corrected sinus node recovery time, P-wave duration, 24-hour Holter ECG to assess AF duration, maximal heart rate in response to isoproterenol (10 micrograms/min), intrinsic heart rate after administration of atropine (0.04 mg/kg) and propranolol (0.1 mg/kg), and atrial effective refractory periods (ERPs) were obtained at baseline (EPS-1) and after 2 to 6 weeks (EPS-2) of VVI pacing alone (n = 4) or VVI pacing and rapid atrial pacing (n = 11). At EPS-2, corrected sinus node recovery time and P-wave duration were prolonged, maximal heart rate and intrinsic heart rate were decreased, atrial ERPs were shortened, and the duration of AF was increased significantly compared with EPS-1. These changes partially reversed toward baseline 1 week after conversion to sinus rhythm. Sinus node function and AF inducibility observed in the control dogs that underwent ventricular pacing alone (n = 4) did not change. Pacing-induced chronic AF induces sinus node dysfunction, prolongs intra-atrial conduction time, shortens atrial refractoriness, and perpetuates AF, changes that reverse gradually after termination of AF.

Cho, Hang Sun; Yang, Hoon Shik; Kim, Kyung Soo

2014-01-01

A fungus ball is an extramucosal fungal proliferation that completely fills one or more paranasal sinuses and usually occurs as a unilateral infection. It is mainly caused by Aspergillus spp in an immunocompetent host, but some cases of paranasal fungal balls reportedly have been caused by Mucor spp. A Mucor fungus ball is usually found in the maxillary sinus and/or the sphenoid sinus and may be black in color. Patients with mucormycosis, or a Mucor fungal ball infection, usually present with facial pain or headache. On computed tomography, there are no pathognomonic findings that are conclusive for a diagnosis of mucormycosis. In this article we report a case of mucormycosis in a 56-year-old woman and provide a comprehensive review of the literature on the "Mucor fungus ball." To the best of our knowledge, 5 case reports (8 patients) have been published in which the fungus ball was thought to be caused by Mucor spp.

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)

2012-01-01

Full Text Available This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation and concha bullosa for patients diagnosed with paranasal sinus fungus balls among the study group were 42.3% and 25%, respectively. About 63.6% sinuses with fungus balls were located on the ipsilateral side of the nasal septal deviation, and 46.2% were located on the ipsilateral side of the concha bullosa. When examined by Pearson’s chi-square test and the chi-squared goodness-of-fit test, no significant statistical difference for the presence of paranasal sinus fungus balls between ipsilateral and contralateral sides of nasal septal deviation and concha bullosa was noted (P=0.292 and P=0.593, resp.. In conclusion, we could not demonstrate any statistically significant correlation between the location of infected paranasal sinus, the direction of nasal septal deviation, and the location of concha bullosa, in location-limited rhinosinusitis lesions such as paranasal sinus fungal balls. We conclude that the anatomical variants discussed herein do not predispose patients to rhinosinusitis.

This paper describes our experience in the management of acute and chronic invasive fungal rhinosinusitis (IFRS) in adults. Medical files of all patients aged >18 years treated in our institutions for IFRS from 2002 to 2013 were retrospectively reviewed. A total of 18 cases (10 acute and 8 chronic) were recorded. In acute form, haematological malignancies represented the principal comorbidity (100%), while in chronic form this was diabetes mellitus (87.5%). All patients received systemic antifungal agents. Endoscopic sinus surgery was performed in 16/18 patients (88.9%). Among patients with an acute IFRS, 4/10 died of fungal infection (40%), on the other side 2/8 patients with chronic IFRS died of the evolution of the mycosis (25%). Acute and chronic IFRS are different entities: in acute form, prognosis is poor, so therapy should be promptly performed, although host immune status and evolution of the haematological disease are key factors for the outcome. In chronic form, a wide surgical excision of the disease is recommended in order to obtain a complete removal of fungal infection. In both forms, early clinical findings are non-specific and ambiguous, so diagnosis depends on a high index of suspicion, taking into account predisposing factors.

2018-03-01

Full Text Available Our work aimed to generate a preliminary estimation of severe and chronic fungal diseases in the Republic of Kazakhstan with a model proposed by LIFE (Leading International Fungal Education. Calculations were carried out on data from 2015. Published results of studies of mycoses in Kazakhstan were identified; in the absence of national data from the scientific literature, the frequency of life-threatening and serious mycoses in defined groups of patients at risk from other countries were taken into account. We also used analogous estimations of mycoses in the Russian Federation. We estimate that 300,824 patients (1.7% of the population were affected by severe and chronic mycotic diseases. There were an estimated 15,172 cases of acute mycoses, notably tinea capitis in children (11,847, Pneumocystis pneumonia and invasive candidiasis, and 285,652 of chronic fungal diseases. The most frequent were chronic recurrent vulvovaginal candidiasis (273,258 cases and chronic pulmonary aspergillosis (6231. There is uncertainty about the prevalence of asthma in adults; the official number is 12,478 patients, but a prevalence estimate of 1.47% from a WHO consortium yields a prevalence of ~170,000 affected. We have used the official figures to generate the prevalence of fungal asthma, but it is likely to be a significant underestimate. Conclusion: Results of investigation indicate significant prevalence of severe and chronic mycoses in the Republic of Kazakhstan.

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.

Sinus drainage is impeded by the transition spaces that the anterior paranasal sinuses drain into, not the ostia themselves. Addressing the transition spaces and leaving the ostia intact, using the minimally invasive sinus technique, should reverse chronic rhinosinusitis. To assess patient benefit following use of the minimally invasive sinus technique for chronic rhinosinusitis. One hundred and forty-three consecutive patients underwent the minimally invasive sinus technique for chronic rhinosinusitis. Symptoms (i.e. blocked nose, poor sense of smell, rhinorrhoea, post-nasal drip, facial pain and sneezing) were recorded using a visual analogue scale, pre-operatively and at six and 12 weeks post-operatively. Patients were also surveyed using the Glasgow benefit inventory, one and three years post-operatively. We found a significant reduction in all nasal symptom scores at six and 12 weeks post-operatively, and increased total quality of life scores at one and three years post-operatively (25.2 and 14.8, respectively). The patient benefits of treatment with the minimally invasive sinus technique compare with the published patient benefits for functional endoscopic sinus surgery.

Background Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by persistent sinonasal inflammation and sinus microbiome dysbiosis. The basis of this heterogeneity is poorly understood. We sought to address the hypothesis that a limited number of compositionally distinct pathogenic bacterial microbiota exist in CRS patients and invoke discrete immune responses and clinical phenotypes in CRS patients.

The paranasal sinuses often harbor distinct bacterial subpopulations, and in the early colonization phases there seems to be a migration from the sinuses to the lower airways, suggesting that independent adaptation...... and evolution take place in the sinuses. Importantly, before the onset of chronic lung infection, lineages with mutations conferring a large fitness benefit in CF airways such as mucA and lasR as well as small colony variants and antibiotic-resistant clones are part of the sinus populations.

Full Text Available Introduction. Invasive fungal infection is among the leading causes of morbidity, mortality, and economic burden for patients with acute leukemia after induction of chemotherapy. In the past few decades, the incidence of invasive fungal infection has increased dramatically. Its management has been further complicated by the increasing frequency of infection by non-Aspergillus molds (e.g. Mucorales. Neutropenic patients are at a high risk of developing an invasive mucormycosis with fulminant course and high mortality rate (35-100%. Case Outline. We are presenting the case of a 72-year-old male with an acute monoblastic leukemia. The patient was treated during five days with hydroxycarbamide 2 × 500 mg/day, followed by cytarabine 2 × 20 mg/sc over the next 10 days. He developed febrile neutropenia, headache, and edema of the right orbital region of the face. Computed tomography of the sinuses revealed shadow in sinuses with thickening of mucosa of the right paranasal sinuses. Lavage and aspirate from the sinuses revealed Rhizopus oryzae. Mucormycosis was successfully treated with amphotericin B (5 mg/kg/day followed by ketoconazole (400 mg/day. Two months later the patient died from primary disease. Conclusion. In patients with acute leukemia who developed aplasia, febrile neutropenia, and pain in paranasal sinuses, fungal infection should be taken into consideration. New and non-invasive methods for taking samples from sinuses should be standardized in order to establish an early and accurate diagnosis of mucormycosis with the source in paranasal sinuses, and to start early treatment by a proper antifungal drug. Clear communication between physician and mycologist is critical to ensure proper and timely sampling of lavage and aspirate from sinuses and correct specimen processing when mucormycosis is suspected clinically.

The primary objective was to ascertain the therapeutic usefulness of homeopathic medicine in the management of chronic sinusitis (CS). Multicentre observational study at Institutes and Units of the Central Council for Research in Homoeopathy, India. Symptoms were assessed using the chronic sinusitis assessment score (CSAS). 17 pre-defined homeopathic medicines were shortlisted for prescription on the basis of repertorisation for the pathological symptoms of CS. Regimes and adjustment of regimes in the event of a change of symptoms were pre-defined. The follow-up period was for 6 months. Statistical analysis was done using SPSS version 16. 628 patients suffering from CS confirmed on X-ray were enrolled from eight Institutes and Units of the Central Council for Research in Homoeopathy. All 550 patients with at least one follow-up assessment were analyzed. There was a statistically significant reduction in CSAS (P = 0.0001, Friedman test) after 3 and 6 months of treatment. Radiological appearances also improved. A total of 13 out of 17 pre-defined medicines were prescribed in 550 patients, Sil. (55.2% of 210), Calc. (62.5% of 98), Lyc. (69% of 55), Phos. (66.7% of 45) and Kali iod. (65% of 40) were found to be most useful having marked improvement. 4/17 medicines were never prescribed. No complications were observed during treatment. Homeopathic treatment may be effective for CS patients. Controlled trials are required for further validation. Copyright © 2012 Elsevier Ltd. All rights reserved.

1996-01-01

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

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

Diagnostic and treatment challenges in management of allergic fungal rhinosinusitis

Full Text Available Among infections pertaining to head and neck rhinosinusitis holds a significant position both with regard to the prevalence and morbidity. Allergic fungal rhinosinusitis (AFRS was initially considered a counterpart of allergic bronchopulmonary aspergillosis when first diagnosed by Sa firstein in 1976 due to its clinical presentations and seemingly similar pathogenesis. Initially only Aspergillus was known as the causative, but now various other fungal species are known to cause chronic rhinosinusitis; hence, the terminology allergic fungal sinusitis was preferred. Exposure to fungi results in similar as asthma in atopic individuals, but then, some nonatopic individuals may also present with similar symptoms. It has also been studied that the presence of serum immunoglobulin E does not ensure the presence of allergy. Till date, there are several controversies regarding pathogenesis, whether humoral or immune mediated, population at risk, variations in presentations, diagnostic parameters, and treatment protocols. In this review, we try to revisit and learn from past documented experiences to further our attempt toward better understanding of the disease process, its diagnosis, and management.

Full Text Available 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.

Sinonasal carcinoma presenting as chronic sinusitis and sequential bilateral visual loss

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.

An unusual foreign body as cause of chronic sinusitis: a case report

Dinerman Harry

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.

To compare the differences in clinicopathologic features of invasive fungal rhinosinusitis caused by Aspergillus and Mucorales, and to discuss the pathogenesis of tissue injury induced by these two kinds of fungi. The clinical and pathologic features of 19 patients with invasive fungal rhinosinusitis due to Aspergillus (group A) and 16 patients with invasive fungal rhinosinusitis due to Mucorales (group M) were retrospectively reviewed. HE, PAS and GMS stains were performed on all the paraffin-embedded tissues. The diagnosis was confirmed by histologic examination and microbiological culture results. Amongst the group A patients, the clinical course was acute in 4 cases and chronic in 15 cases. Thirteen cases had underlying predisposing conditions, including diabetes (number = 4), malignant tumor (number = 5), history of trauma (number = 1) and radical maxillary sinus surgery (number = 3). Follow-up information was available in 13 patients. Seven of them died, 4 due to fungal encephalopathy and 3 due to underlying diseases. Amongst the group M patients, the clinical course was acute in 14 cases and chronic in 2 cases. Fourteen cases had underlying predisposing conditions, including diabetes (number = 8), malignant tumor (number = 5) and history of wisdom tooth extraction (number = 1). Follow-up information was available in 14 patients. Four of them died of fungal encephalopathy. There was significant difference in clinical onset between the two groups (P = 0.01). There was however no difference in terms of underlying predisposing conditions and disease mortality. Histologically, the microorganisms in group A patients formed fungal masses and attached to the mucosal surface, resulting in necrotic bands (11/19). Epithelioid granulomas were conspicuous but multinucleated giant cells were relatively rare. Deep-seated necrosis, granulomatous inflammation against fungal organisms (3/19) and vasculitis with thrombosis (4/19) were not common. On the other hand, large areas

The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq 186 Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 ± 0.5 by patients self-evaluation and by physicians scoring of +0.81 ± 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

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

patients with aspergillosis. Among the 18 patients presenting with neoplasia, 8 patients (44.44% showed HPE of squamous. CONCLUSION The orbital complications of PNS diseases include chronic sinusitis, benign and malignant neoplasia and invasive and noninvasive fungal involvement of PNS. Vision was more affected in patients with fungal infection of the sinuses with orbital extension. CT scan is the mainstay in diagnosis of orbital involvement. In malignancies of the paranasal sinuses involving the orbit, an intraoperative assessment of involvement of the orbital periosteum and orbital contents is important in determining whether orbital exenteration should be added to total maxillectomy.

To determine the prevalence,location, and distribution of sinus tracts in patients referred for endodontic consultation. This cohort study included 1,119 subjects referred for endodontic consultation, 108 of whom presented with sinus tracts. Following clinical and radiographic examination, the diameter of the rarifying osteitis lesion on the radiograph was measured and the path and origin of the sinus tracts determined. Signs and symptoms, tooth site,buccal/lingual location, and diameter were recorded. Data were statistically analyzed using Pearson chi-square test. Sinus tracts originated mainly from maxillary teeth (63.1%); only 38.9% originated from mandibular teeth. Chronic periapical abscess was the most prevalent diagnosed origin (71.0%). Broken restorations were highly associated with the presence of sinus tracts (53.0%). The most frequent site of orifices was buccal(82.4%), followed by lingual or palatal (12.0%). Orifices on the lingual aspect of the gingiva were observed in mandibularmolars. There was an 86.8% correlation between the occurrence of an apically located sinus tract and apical rarifying osteitis(P<.01). Sinus tract in the lingual or palatal aspect of the gingiva is relatively common. Practitioners should look for signs of sinus tract during routine examination

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

Invasive fungal rhinosinusitis (IFRS) is a life-threatening inflammatory disease that affects immunocompromised patients, but animal models of the disease are scarce. This study aimed to develop an IFRS model in neutropenic rats. The model was established in three consecutive steps: unilateral nasal obstruction with Merocel sponges, followed by administration of cyclophosphamide (CPA), and, finally, nasal inoculation with Aspergillus fumigatus. Fifty healthy Wistar rats were randomly divided into five groups, with group I as the controls, group II undergoing unilateral nasal obstruction alone, group III undergoing nasal obstruction with fungal inoculation, group IV undergoing nasal obstruction with administration of CPA, and group V undergoing nasal obstruction with administration of CPA and fungal inoculation. Hematology, histology, and mycology investigations were performed. The changes in the rat absolute neutrophil counts (ANCs) were statistically different across the groups. The administration of CPA decreased the ANCs, whereas nasal obstruction with fungal inoculation increased the ANCs, and nasal obstruction did not change them. Histological examination of the rats in group V revealed the hyphal invasion of sinus mucosa and bone, thrombosis, and tissue infarction. No pathology indicative of IFRS was observed in the remaining groups. Positive rates of fungal culture in tissue homogenates from the maxillary sinus (62.5%) and lung (25%) were found in group V, whereas groups I, II, III, and IV showed no fungal culture in the homogenates. A rat IFRS model was successfully developed through nasal obstruction, CPA-induced neutropenia, and fungal inoculation. The disease model closely mimics the pathophysiology of anthropic IFRS.

Given the importance of rapid diagnosis for fungal rhinosinusitis, this study aimed to evaluate the use of nested PCR to identify Aspergillus and Mucor species in clinical samples from patients with suspected fungal rhinosinusitis. Functional endoscopic sinus surgery specimens were collected from 98 patients with rhinosinusitis from 2012 to 2013. All samples were ground and cultured on sabouraud dextrose agar. The isolated fungi were identified based on their macroscopic and microscopic features. Fungal DNA was extracted from the tissue samples and nested PCR was performed with two sets of primers for Mucor and Aspergillus. Direct microscopic showed that 5.1% contained fungal components and 9.2% exhibited growth of fungi in culture. The most common agents isolated were Aspergillus fumigatus (n= 3), Aspergillus flavus (n=2), Penicillium sp (n=3) and Alternaria sp. (n=1). Mucor sp. was identified in the pathology smear from 1 patient. Positive results for fungal rhinosinusitis were obtained for a total of 10.2% by culture or pathology smear. Positive PCR results were obtained in 72 samples for Aspergillus and 31 samples for Mucor. Our results suggest that endoscopic sinus surgery specimens are not suitable for nested PCR, probably because of the accumulation of fungi that contaminate the environmental air. This drawback is a limiting factor for diagnosis with nasal cavity specimens. Therefore, molecular methods and conventional culture techniques are helpful complementary diagnostic methods to detect fungal rhinosinusitis and determine appropriate management for these patients.

Invasive aspergillosis (IA) is a severe disseminated fungal disease that occurs mostly in immunocompromised patients. However, central nervous system IA, combining meningitis and skull base involvement, does not occur only in groups with classic risk factors for IA; patients with chronic renal failure and diabetes mellitus are also at risk for more chronic forms. In both of our proven IA cases, voriconazole monotherapy was effective without surgery, and cerebrospinal fluid and serum 1,3-β-d-glucan test results were initially positive, in contrast to galactomannan antigen results.

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

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

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

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

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

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)

Rhino-orbitocerebral mucormycosis associated with cavernous sinus thrombosis: case report

Directory of Open Access Journals (Sweden)

Haber, Daniel Martiniano

2008-12-01

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

Draining cutaneous sinus tract in chin area may be caused by chronic periapical dental infections. Misdiagnosis of these lesions usually leads to destructive invasive treatment of the sinus tract that is not correct and curative. A 31-year-old male patient referred to us with a chronically draining lesion on his chin. The lesion previously was misdiagnosed by medical doctors and had undergone two times surgery with a focus on the skin lesion and had received antibiotic therapy for a prolonged period of time. After clinical and radiologic examination the dental origin of the lesion was evident and proper endodontic and surgical treatment was performed. Three months later, after the treatment, the lesion showed total healing and reoccurrence occurred. The key to successful treatment of cutaneous sinus tract of dental origin must be in appropriate communication between the dentist and the physician in order to achieve correct diagnosis and therapy in such cases.

The primitive tentorial, occipital, and falcine sinuses are thought to attain the adult pattern or regress between the fetal stage and adulthood. The anatomy of these three primitive dural sinuses has seldom been studied in the infant population, and it remains unclear when these dural sinuses reach the adult condition. Using computed tomography digital subtraction venography (CT-DSV), we analyzed the anatomy of these embryonic dural sinuses in infants. We included 13 infants who underwent CT-DSV prior to neurosurgery and 35 cases with unruptured cerebral aneurysms as normal adult controls. Three embryonic dural sinuses, i.e., the primitive tentorial, occipital, and falcine sinuses, were retrospectively analyzed in CT-DSV images of infants and adults. We also analyzed the drainage patterns of the superficial middle cerebral vein (SMCV), determined by the connection between the primitive tentorial sinus and the cavernous sinus. The primitive tentorial, occipital, and falcine sinuses were present in 15.4%, 46.2%, and none of the infants, respectively, and in 10.0, 8.6, and 2.9% of the adults, respectively. The difference in SMCV draining pattern between infants and adults was insignificant. The incidence of the occipital sinus was significantly higher in infants than in adults. The connection between the primitive tentorial sinus and the cavernous sinus appears to be established before birth. The occipital sinus is formed at the embryonic stage and mostly regresses after infancy. The falcine sinus is usually obliterated prenatally. Our findings form the basis for interventions by pediatric interventional neuroradiologists and neurosurgeons.

Although encephalocele is a rare congenital abnormality, secondary encephalocele is extremely rare and can cause fatal complications. Here, we report a case of secondary encephalocele caused by frontal sinus wall defect due to chronic sinusitis, which was completely removed by cranialization with autologous bone graft. A 50-year-old man with a 10-year history of chronic sinusitis visited our hospital due to suddenly altered mentality characterized by stupor. Computerized tomography scanning and magnetic resonance imaging revealed an enlarged left frontal sinus with sinusitis. The frontal sinus cavity was calcified, and the left frontal lobe had herniated into the cavity accompanied by yellow pus. A large dural defect was also found around the frontal sinus area. After removal of the abscess and some of the frontal lobe, frontal skull base repair by cranialization was performed using autologous bone graft. Streptococcus pneumoniae was cultured from the cerebrospinal fluid (CSF), necessitating treatment with antibiotics. After the operation, the mental status of the patient improved and no CSF leakage was observed. In addition to correct diagnosis and early treatment including antibiotics, the surgical repair of defects is needed in patients with secondary encephalocele to prevent further episodes of meningitis. Surgical correction of frontal sinus encephalocele can be achieved through bifrontal craniotomy or endoscopic transnasal repair. If a patient has CSF leakage, open craniotomy may facilitate repair of the dural defect and allow for cranialization of the sinus. Removal of dysplastic herniated brain tissue and cranialization of the frontal sinus may be a good option for treating secondary encephalocele and its associated complications, including meningitis, abscess formation, and infarction of the herniated brain parenchyma.

The incidence and prevalence of fungal infections in Russia is unknown. We estimated the burden of fungal infections in Russia according to the methodology of the LIFE program (www.LIFE-worldwide.org). The total number of patients with serious and chronic mycoses in Russia in 2011 was three million. Most of these patients (2,607,494) had superficial fungal infections (recurrent vulvovaginal candidiasis, oral and oesophageal candidiasis with HIV infection and tinea capitis). Invasive and chronic fungal infections (invasive candidiasis, invasive and chronic aspergillosis, cryptococcal meningitis, mucormycosis and Pneumocystis pneumonia) affected 69,331 patients. The total number of adults with allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation was 406,082. © 2015 Blackwell Verlag GmbH.

Breathing vitally serves body homeostasis. The prevalence of upper airway infections is often taken as an indicator of overall health status of a population living at a given time. In the present study we examined the unearthed remains of skulls from the XIII-XV century inhabitants searching for signs of maxillary sinusitis. Maxillary sinuses of the skulls of 92 individuals were inspected macroscopically and, if necessary, endoscopically. Osseous changes, including the pitting and abnormal spicule formation were present in 69 cases (75.0 %). It was found that, overall, dental infection was a major cause of maxillary sinusitis (18.8 %). Severe bone changes were observed in the adults' skulls, but were also present in the sinus walls of children's skulls. Post-inflammatory changes were manifest as remodeling and damage to the sinus walls. The results indicate that both children and adults of the Middle Ages suffered from chronic sinusitis. These observations confirm that the climate, environment, and lifestyle of the medieval populations contributed to the morbidity of the upper respiratory tract.

The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

Compositionally and functionally distinct sinus microbiota in chronic rhinosinusitis patients have immunological and clinically divergent consequences.

Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by persistent sinonasal inflammation and sinus microbiome dysbiosis. The basis of this heterogeneity is poorly understood. We sought to address the hypothesis that a limited number of compositionally distinct pathogenic bacterial microbiota exist in CRS patients and invoke discrete immune responses and clinical phenotypes in CRS patients. Sinus brushings from patients with CRS (n = 59) and healthy individuals (n = 10) collected during endoscopic sinus surgery were analyzed using 16S rRNA gene sequencing, predicted metagenomics, and RNA profiling of the mucosal immune response. We show that CRS patients cluster into distinct sub-groups (DSI-III), each defined by specific pattern of bacterial co-colonization (permutational multivariate analysis of variance (PERMANOVA); p = 0.001, r 2  = 0.318). Each sub-group was typically dominated by a pathogenic family: Streptococcaceae (DSI), Pseudomonadaceae (DSII), Corynebacteriaceae [DSIII(a)], or Staphylococcaceae [DSIII(b)]. Each pathogenic microbiota was predicted to be functionally distinct (PERMANOVA; p = 0.005, r 2  = 0.217) and encode uniquely enriched gene pathways including ansamycin biosynthesis (DSI), tryptophan metabolism (DSII), two-component response [DSIII(b)], and the PPAR-γ signaling pathway [DSIII(a)]. Each is also associated with significantly distinct host immune responses; DSI, II, and III(b) invoked a variety of pro-inflammatory, T H 1 responses, while DSIII(a), which exhibited significantly increased incidence of nasal polyps (Fisher's exact; p = 0.034, relative risk = 2.16), primarily induced IL-5 expression (Kruskal Wallis; q = 0.045). A large proportion of CRS patient heterogeneity may be explained by the composition of their sinus bacterial microbiota and related host immune response-features which may inform strategies for tailored therapy in this patient population.

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

The purpose of this study was to determine the effect of uncinectomy without sinusotomy and natural ostial dilatation on maxillary sinus ventilation in chronic rhinosinusitis. Twenty patients with chronic rhinosinusitis were included in this study. The patients were randomly divided into two groups. Group 1 consisted of patients with uncinectomy (n = 10), while group 2 was made up of patients treated with natural ostial dilatation (n = 10). The CO(2) tension and pressure levels of the maxillary sinus during inspiration and expiration phases were obtained and compared before and after the procedures within and between the groups. The mean CO(2) tension levels in both groups were significantly decreased after the procedures. The mean maxillary sinus pressure during inspiration was significantly decreased to a negative value after uncinectomy; however, no significant change was observed during expiration. There were no significant changes in maxillary sinus pressures after natural ostial dilatation procedure. Both uncinectomy and natural ostial dilatation seem to be equally effective in decreasing maxillary sinus pCO(2) levels. The effects of decreased maxillary sinus pressure during inspiration after uncinectomy on mucociliary clearance and development mechanisms of chronic rhinosinusitis seem to be worth investigating.

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)

Median mental sinus in twins.

Sinus on the chin can be the result of a chronic apical abscess due to pulp necrosis of a mandibular anterior tooth. The tooth is usually asymptomatic, and a dental cause is therefore not apparent to the patient or the unsuspecting clinician. Not infrequently, the patient may seek treatment from a dermatologist or general surgeon instead of a dentist. Excision and repair of the fistula may be carried out with subsequent breakdown because the dental pathology is not removed. This paper reports the presence of median mental sinus of dental origin in twins. One case healed following root canal therapy while the other required both root canal therapy and surgery to eliminate the infection.

Full Text Available BACKGROUND Nasal polyposis is a disease entity characterised by formation of pseudoedema of sinonasal mucus membrane progressing to form polyps. It presents clinically with nasal obstruction and fleshy masses in the nasal cavity. The nasal mucosa reacts to formation of polypi in allergic fungal sinusitis also. The present study is an attempt to demonstrate possible fungal elements from the polypi removed during surgery by KOH study and HPE study. The aim of the study is to find out the incidence of fungal elements in sinonasal polyposis. MATERIALS AND METHODS 50 patients attending the ENT OPD for nasal obstruction and showing polypi on anterior rhinoscopy were selected. All the patients were subjected to surgery and specimens collected were subjected to KOH study and histopathology to demonstrate fungal elements. RESULTS Among 50 patients, the age range was from 9-57 years; mean age- 36.46 years. The male-to-female ratio was 1.5:1. Deviated nasal septum was found in 38% of patients. Among the unilateral cases, 47% were antrochoanal polyps and 53% were ethmoid polyps. Out of 50 patients, only 3 specimens were positive for fungal elements with KOH study and only 2 cases with fungal culture. Thus, the incidence of fungal elements in sinonasal polyposis was 6%. CONCLUSION The incidence of fungal elements in sinonasal polyposis was 6%. Histopathological examination of polypectomy specimen was negative for invasive fungal disease and showed inflammatory changes only. There is no difference in the detection of the presence of fungal by two methods.

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

The aim of this study was to assess the influence of spray cryotherapy on wound healing following endoscopic sinus surgery (ESS). A prospective, randomized, double-blinded, controlled trial. The study included 22 consecutive adult patients with chronic rhinosinusitis with and without polyps scheduled for bilateral ESS. At the end of the surgical procedure, patients were randomized to the distribution of spray cryotherapy in one middle meatus and saline contralaterally. Outcomes were only measured for endoscopy scores. Thus, postoperative healing and the amount of edema, crusting, secretions, and scarring were assessed using the validated Lund-Kennedy and Perioperative Sinus Endoscopy (POSE) scores. There were no baseline differences concerning POSE and Lund-Kennedy scores between the two groups. Nevertheless, a significant difference was recorded at one, 2, 4, 8, and 12 weeks in both POSE (P = .001, P = .012, P = .02, P = .006, P = .001) and Lund-Kennedy (P = .002, P = .005, P = .02, P = .02, P = .03) scores. These preliminary results reveal an improvement in postoperative scores, demonstrating enhanced healing following spray cryotherapy. However, without patient subjective outcomes, the study is limited. Additional studies with longer follow-up and larger samples are needed to describe the effects of cryotherapy on wound healing. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

Directory of Open Access Journals (Sweden)

Anil S Harugop

2013-01-01

Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

Background: Rabbits are useful for preclinical studies of sinusitis because of similar physiologic features to humans. The objective of this study is to develop a rabbit model of sinusitis that permits assessment of microanatomy and sampling for evaluating shifts in the sinus microbiota during the development of sinusitis and to test how the mucociliary clearance (MCC) defect might lead to dysbiosis and chronic rhinosinusitis (CRS). Methods: Generation of CRS was accomplished with an insertion of a sterile sponge into the left middle meatus of New Zealand white rabbits (n = 9) for 2 weeks. After sponge removal, 4 rabbits were observed for another 10 weeks and evaluated for CRS using endoscopy, microCT, visualization of the functional micro-anatomy by micro-optical coherence tomography (μOCT), and histopathological analysis of the sinus mucosa. Samples were taken from the left middle meatus and submitted for microbiome analysis. Results: CT demonstrated opacification of all left sinuses at 2 weeks in all rabbits (n = 9), which persisted in animals followed for another 12 weeks (n = 4). Histology at week 2 showed mostly neutrophils. On week 14, significant infiltration of plasma cells and lymphocytes was noted with increased submucosal glands compared to controls (p = 0.02). Functional microanatomy at 2 weeks showed diminished periciliary layer (PCL) depth (p < 0.0001) and mucus transport (p = 0.0044) compared to controls despite a thick mucus layer. By 12 weeks, the thickened mucus layer was resolved but PCL depletion persisted in addition to decreased ciliary beat frequency (CBF; p < 0.0001). The mucin fermenting microbes (Lactobacillales, Bacteroidales) dominated on week 2 and there was a significant shift to potential pathogens (e.g., Pseudomonas, Burkholderia) by week 14 compared to both controls and the acute phase (p < 0.05). Conclusion: We anticipate this reproducible model will provide a means for identifying underlying mechanisms of airway-surface liquid

The olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable and it is not clear whether functional endoscopic sinus surgery (FESS) significantly improves olfactory function. This study was performed to evaluate the influences of FESS on olfactory function in patients with chronic rhinosinusitis using three different types of olfactory tests. Seventy patients with chronic rhinosinusitis were administered the University of Pennsylvania Smell Identification Test (UPSIT), a single staircase phenyl ethyl alcohol odor detection threshold test (STT), and a short-term odor memory/discrimination test a day before and 6 months after FESS. A questionnaire inquiring about the patients' self-perception of olfactory function was administered also. Independent ratings of the severity of chronic rhinosinusitis before FESS were established from CT scans. Fifty-two (74.3%) of the patients reported that their olfactory function was impaired before surgery, and 68.6% of the patients reported impaired olfactory function after surgery, a difference that was not significant. No meaningful changes in any of the olfactory test scores were noted 6 or more months after FESS. Preoperatively, small correlations between CT scores and the symptom scores (r = 0.278; p = 0.024), threshold scores (r = -0.27; p = 0.031), and UPSIT scores (r = -0.36; p = 0.003) were observed. In patients with severe rhinosinusitis, FESS had little impact on the ability to smell, regardless of the method for assessing smell function. Subtle associations between olfactory function and the severity of chronic rhinosinusitis determined by CT were observed, however, preoperatively. The olfactory test measures were correlated with one another both pre- and postoperatively.

Atrial fibrillation (AF) is the most common cardiac arrhythmia. While the arrhythmia was initially thought to be little more than a nuisance, it is now clear that AF has a significant negative impact on quality of life and a corresponding increase in both morbidity and mortality. The aim of this study was to identify Doppler echographic patterns that allow prediction of atrial fibrillation reduction and maintenance of sinus rhythm within 12 months. One hundred and thirty patients having permanent atrial fibrillation, recent (51) or chronic (79) are included in the study, excepting those with valvular heart disease or thyroid dysfunction. The mean age was 63.5 +/- 11.3 years. Both transthoracic and transoesophageal echocardiography was performed using a Philips SONOS 5500 Echograph, before cardioversion. Were studied: end diastolic and systolic left ventricular diameters, left ventricular ejectionnal fraction, left atrial area (LAA), left atrial diameter, left atrial appendage area and peak emptying velocities of the left atrial appendage (PeV). Sinus rhythm was re-established in 102 patients (44 having recent and 58 chronic atrial fibrillation). Sinus rhythm was maintained for 12 months in 79 patients. Within the echographic parameters studied, the left atrial area (LAA) and peak emptying velocities of left atrial appendage (PeV) before cardioversion were the best predictors of restoration of sinus rhythm. On monovariate analysis, SOG is significantly lower and PicV is significantly higher in patients whose sinus rhythm had been restored in comparison with those with permanent atrial fibrillation. (Mean SOG: 27.7 +/- 7.62 vs. 34 +/- 7,6 cm2, ppredict on mono and multivariate analysis (p=0.05, OR=0.5, IC=0.36 à 3.56), re-establishing of sinus rhythm whereas in patients with chronic atrial fibrillation, peak emptying velocity of left atrial appendage predict better re-establishing of sinus rhythm (p=0.04, OR=1.29, IC=0.12 à 4.23). The threshold values of LAA and Pe

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.

Tissue infarction is known as one of the characteristic features of invasive fungal sinusitis (IFS). The purpose of this study was to investigate the prevalence and characteristic MR imaging findings of cervicofacial tissue infarction (CFTI) associated with acute IFS. We retrospectively reviewed MR images in 23 patients with histologically or microbiologically proven acute IFS. CFTI was defined as an area of lack of enhancement in and around the sinonasal tract on contrast-enhanced T1-weighted images. We divided CFTI into two groups, i.e., intrasinonasal and extrasinonasal. Particular attention was paid to the location of extrasinonasal CFTI and the signal intensity of CFTI on T1- and T2-weighted images. The presence of bone destruction on CT scans was also recorded. CFTI was found in 17 (74%) of 23 patients. All of these 17 patients had intrasinonasal CFTI, and 13 patients also had extrasinonasal CFTI. All 13 patients with extrasinonasal CFTI died of disease directly related to IFS. Various locations were involved in the 13 patients with extrasinonasal CFTI, including the orbit (n = 8), infratemporal fossa (n = 7), intracranial cavity (n = 3), and oral cavity and/or facial soft tissue (n = 4). Various signal intensities were noted at the area of CFTI on T1- and T2-weighted images. Bone destruction was found on CT scans in only 3 of 17 patients with CFTI. CFTI with preservation of the bony wall of the involved sinonasal tract may be a characteristic MR imaging finding of acute IFS. The mortality is very high once the lesion extends beyond the sinonasal tract.

2011-01-01

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

Chronic rhinosinusitis is a common disease process in humans; however, in the primate population of gorillas, it has rarely been described. This case describes lifesaving sinus surgery on a critically ill gorilla performed by a human otolaryngology team in collaboration with the gorilla's veterinary medicine team. The 35-year-old western silverback gorilla was treated for 3 months with aggressive medical therapy for a worsening sinus infection. When his condition became severe, a computed tomography (CT) scan was performed showing advanced chronic rhinosinusitis with nasal polyps vs other masses and some bone erosion. As his condition deteriorated further, a tertiary otolaryngology team performed sinus surgery using the latest technology available, including image guidance, steroid-eluting sinus stents, and balloon sinus dilation. The postoperative course was complicated by subcutaneous infection and eventual fistulization. Fortunately, with culture-directed antibiotic therapy his condition gradually improved. One year later he required revision sinus surgery. At that point allergy testing was performed followed by appropriate allergy medical therapy. Now, 3 years out from his initial surgery, he continues to do well and has fathered a young female gorilla. This case represents a unique collaboration between human physicians and veterinarians. The combined medical approach was critical to heal this ailing gorilla. This case discusses many of the challenges and offers recommendations for physicians who may be involved with similar care of animals in the future. The success of the surgical and medical treatment of this gorilla's life-threatening sinus infection required many experts, careful planning, and corporate generosity. The interaction between human and animal medicine would not have been successful without the close and trusting collaborations between human and veterinary health providers. We encourage human healthcare providers to seek volunteer

Maxillary sinusitis and periapical abscess following periodontal therapy: a case report using three-dimensional evaluation.

Science.gov (United States)

Huang, Chih-Hao; Brunsvold, Michael A

2006-01-01

Maxillary sinusitis may develop from the extension of periodontal disease. In this case, reconstructed three-dimensional images from multidetector spiral computed tomographs were helpful in evaluating periodontal bony defects and their relationship with the maxillary sinus. A 42-year-old woman in good general health presented with a chronic deep periodontal pocket on the palatal and interproximal aspects of tooth #14. Probing depths of the tooth ranged from 2 to 9 mm, and it exhibited a Class 1 mobility. Radiographs revealed a close relationship between the root apex and the maxillary sinus. The patient's periodontal diagnosis was localized severe chronic periodontitis. Treatment of the tooth consisted of cause-related therapy, surgical exploration, and bone grafting. A very deep circumferential bony defect at the palatal root of tooth #14 was noted during surgery. After the operation, the wound healed without incidence, but 10 days later, a maxillary sinusitis and periapical abscess developed. To control the infection, an evaluation of sinus and alveolus using computed tomographs was performed, systemic antibiotics were prescribed, and endodontic treatment was initiated. Two weeks after surgical treatment, the infection was relieved with the help of antibiotics and endodontic treatment. Bilateral bony communications between the maxillary sinus and periodontal bony defect of maxillary first molars were shown on three-dimensional computed tomographs. The digitally reconstructed images added valuable information for evaluating the periodontal defects. Three-dimensional images from spiral computed tomographs (CT) aided in evaluating and treating the close relationship between maxillary sinus disease and adjacent periodontal defects.

Full Text Available Midline congenital malformation of the nose is a very rare presentation and it's midline situation seems curious and is very difficult to explain on the basis of the present day conception of the embryology of the nose. The prevalence of lower lip sinuses has been estimated to be about 0.001 % of the general population. Upper lip sinuses are even more uncommon. We herein report a case of a 13 years old girl having congenital sinus affecting the upper part of the columella.

In spite of developing new drugs and modern formulations, the treatments of chronic fungal infections are still challenging. Fibrous wound dressings are new suggestions for the treatment of chronic superficial infections. In the present study, we formulated an antifungal agent, terbinafine hydrochloride (TFH), which is a hydrophobic drug, in wound dressings prepared by electrospun polycaprolactone, polycaprolactone/gelatin (50:50 w/w) and gelatin. To obtain more water-stable meshes, the preparations were treated by glutaraldehyde and their properties were determined before and after treatment. The morphology of fibrous meshes was observed by scanning electron microscopy. Drug loading efficiency and release rate were measured by high performance liquid chromatography (HPLC) and the release rate was monitored for 144h. Antifungal tests were performed on Trichophyton mentagrophytes, Aspergillus fumigatus and Candida albicans cultured on Muller-Hinton agar. The toxicity of the meshes was measured after 24h and 14days by MTT assay. Terbinafine loading of polycaprolactone/gelatin (50:50) was 100% and it released the highest amount of TFH too. In antifungal tests, all samples were able to hinderT. mentagrophytes and A. fumigatus but not C. albicans growth among them, polycaprolactone fibers made the largest inhibition zone. In MTT assay, none of prepared samples showed toxicity against L929 cells. Teken together, the prepared TFH-loaded PCL/gelatin electrospun meshes were able to release TFH slowly and in a steady state in time. With respect to no obvious cytotoxicity in MTT assay and stong antifungal activity toward T. mentagrophytesin vitro, these TFH-based meshes could be considered as potential candidates in clinical application as wound dressing for treatment of chronic dermatophytosis.

Full Text Available Objectives: To define the role of endoscopic evaluation of middle meatus in adult patients clinically diagnosed to have chronic rhino-sinusitis and its ability to predict intra-sinus mucosal involvement as compared to CT scan.Methods: This prospective analytical study was conducted on consecutive patients with diagnosis of chronic rhino-sinusitis who were symptomatic and fulfilled the American Academy of Otolaryngology - Head and Neck Surgery Task Force criteria. The patients were enrolled prospectively and were subjected to rigid diagnostic nasal endoscopy and classified as defined by the revised Sinus Allergy Health Partnership Task Force criteria. The patients then underwent non contrast CT sinuses on the same day. Results were analyzed as a diagnostic test evaluation using CT as a gold standard.Results: Among the 75 study patients with symptom based chronic rhino-sinusitis, nasal endoscopy was abnormal in 65 patients (87%. Of these patients, 60/65 (92% showed positive findings on CT scan. Ten patients had normal endoscopy, of these 6/10 (60% had abnormal CT scan. Sensitivity and specificity of diagnostic nasal endoscopy against CT scan were 91% (95% CI: 81-97 and 44% (95% CI: 14-79, respectively. The likelihood ratio for positive nasal endoscopy to diagnose chronic rhino-sinusitis was 1.6 and the likelihood ratio to rule out chronic rhino-sinusitis when endoscopy was negative was 0.2.Conclusion: Nasal endoscopy is a valid and objective diagnostic tool in the work up of patients with symptomatic chronic rhino-sinusitis. When clinical suspicion is low (90% of patients when clinical suspicion is high (88% as defined in this study by AAO-HNS Task Force criteria. Negative endoscopy, however, does not totally exclude the sinus disease in patients fulfilling task force criteria. CT scan may be needed on follow-up if there is clinical suspicion in 10% of these patients who are negative on endoscopy if symptoms persists. It is thus possible to reduce

Anatomic variations in skull base anatomy may predispose the surgeon to inadvertent skull base injury with resultant cerebrospinal fluid (CSF) leak during functional endoscopic sinus surgery (ESS). Our objective was to compare preoperative sinus imaging of patients who underwent FESS with and without CSF leak to elucidate these variations. In this retrospective case-control study, 18 patients with CSF leak following FESS for chronic rhinosinusitis (CRS) from 2000 to 2011 were compared to 18 randomly selected patients who underwent preoperative imaging for FESS for CRS. Measurements were obtained from preoperative computed tomography images with specific attention to anatomic differences in cribriform plate and ethmoid roof heights in the coronal plane, and the skull base angle in the sagittal plane. Mean values of measured variables were compared using a nonparametric Mann-Whitney test. When compared to controls, patients with CSF leak demonstrated a greater angle of the skull base in the sagittal plane (P variations may help to prevent iatrogenic CSF leak.

Durr, Megan L; Goldberg, Andrew N

2014-01-01

To describe a technique of endoscopic medial maxillectomy with mucosal flap for postoperative maxillary sinus mucoceles and to present a case series of subjects who underwent this procedure. This case series includes four subjects with postoperative maxillary sinus mucoceles who underwent resection via endoscopic partial medial maxillectomy with a mucosal flap. We will discuss the clinical presentation, imaging characteristics, operative details, and outcomes. Four subjects are included in this study. The average age at the time of medial maxillectomy was 52 years (range 35-65 years). Three subjects (75%) were female. One subject (25%) had bilateral postoperative maxillary sinus mucoceles. Two subjects (50%) had unilateral right sided mucoceles, and the remaining subject had a unilateral left sided mucocele. All subjects had a history of multiple sinus procedures for chronic sinusitis including Caldwell-Luc procedures ipsilateral to the postoperative mucocele. All subjects underwent endoscopic medial maxillectomy without complication and were symptom free at the last follow up appointment, average 24 months (range 3-71 months) after medial maxillectomy. For postoperative maxillary sinus mucoceles in locations that are difficult to access via the middle meatus antrostomy, we recommend endoscopic medial maxillectomy with mucosal flap. Our preliminary experience with four subjects demonstrates complete resolution of symptoms after this procedure. Copyright © 2014 Elsevier Inc. All rights reserved.

Sinus on the chin can be the result of a chronic apical abscess due to pulp necrosis of a mandibular anterior tooth. The tooth is usually asymptomatic, and a dental cause is therefore not apparent to the patient or the unsuspecting clinician. Not infrequently, the patient may seek treatment from a dermatologist or general surgeon instead of a dentist. Excision and repair of the fistula may be carried out with subsequent breakdown because the dental pathology is not removed. This paper reports...

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)

Kusaka, N.; Sugiu, K.; Katsumata, A.; Nakashima, H.; Tamiya, T.; Ohmoto, T.

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.)

Chronic rhinosinusitis is the most common chronic illness in the United States. An understanding of the anatomy of the paranasal sinuses, their functioning in health and in disease, and the contributing factors that are critical to the pathogenesis of rhinosinusitis is essential for nurses caring for patients with this prevalent disease. This paper will provide the otorhinolaryngology (ORL) nurse with an overview of the scientific principles important in rhinosinusitis, as well as presenting a framework for the understanding of rhinosinusitis and its treatment. (This paper is the first in a series of two articles. The second part will review the diagnosis and treatment of chronic rhinosinusitis.)

Optic neuropathy due to allergic fungal rhinosinusitis

Directory of Open Access Journals (Sweden)

Jiji Tresa Cyriac

2011-01-01

Full Text Available An uncommon case of allergic fungal rhinosinusitis presented to the ophthalmology outpatient department of our hospital with complaints of blurred vision in the right eye of a few days duration and vague complaints of pain around the eyes. The visual acuity on examination was grossly reduced in the right eye and normal in the left eye. Color vision was normal. Anterior segment examination including pupils was normal. Dilated fundus examination was normal except for temporal pallor in the right optic disc. Automated perimetry and magnetic resonance imaging (MRI scan of brain and orbit were done. The imaging report showed a bilateral pansinusitis with pressure on the right optic nerve. Perimetry showed a superior field defect on the right side. ENT consultation and computed tomography (CT with contrast helped to diagnose this as a case of allergic fungal rhinosinusitis. The patient was started on systemic steroids under the care of the ENT surgeon. After a few days, pre-operative assessment showed a gross improvement of visual acuity. Endoscopic sinus surgery was done to remove the polyps and thick mucus material. Histopathologic examination confirmed allergic fungal mucin. Days after surgery, the visual acuity improved further and repeat perimetry showed gross improvement in the visual field. Good history taking and a detailed ophthalmic examination, keeping in mind the probable causes of loss of vision of few days duration with no findings other than a decreased visual acuity and a suspicious disc, were key to the early diagnosis and investigation in this case. This helped in early referral and management of the case before permanent damage and irreversible visual loss occurred. The optic nerve is a cranial nerve which, once damaged permanently, will not regenerate. The amount of sinus involvement was extensive on both sides and invariably the left optic nerve would have been involved in a few days, if intervention was delayed.

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

Mantoni, M.; Larsen, P.; Hansen, H.; Tos, M.; Berner, B.; Oerntoft, S.

1996-01-01

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.)

Crestal Sinus Augmentation in the Presence of Severe Sinus Mucosal Thickening: A Report of 3 Cases.

Science.gov (United States)

Fang, Yiqin; An, Xueyin; Jeong, Seung-Mi; Choi, Byung-Ho

2018-06-01

In the presence of severe sinus mucosal thickening, the ostium can be blocked when the sinus membrane is lifted, causing drainage disturbances and sinusitis. Here, we present 3 cases in which maxillary sinus floor elevation was performed using a crestal approach in the presence of severe sinus mucosal thickening (>10 mm). The effects of maxillary sinus floor elevation using the crestal approach technique on sinus mucosal thickening and bone formation in the sinus were evaluated using cone beam computed tomography. None of the patients exhibited an increase in sinus membrane thickness. No complications were encountered during the follow-up periods, and bone formation was observed around the implants at the sinus floor. All implants were functioning successfully. Maxillary sinus floor elevation using the crestal approach technique in the presence of severe sinus mucosal thickening allows for minimally invasive sinus grafting and simultaneous implant placement and does not increase sinus membrane thickness.

Invasive maxillary aspergillosis masquerading as malignancy in two cases: Utility of cytology as a rapid diagnostic tool

Directory of Open Access Journals (Sweden)

Divya Sharma

2012-01-01

Full Text Available Fungi have emerged as important etiological agents for chronic sinusitis. Invasive aspergillosis has been reported in immunocompromised individuals or diabetics; however, it is uncommonly seen in immunocompetent patients. Definitive diagnosis of these lesions is based on histological examination and fungal culture. We report two cases of invasive maxillary lesions in immunocompetent patients, clinically suspected of malignancy; however, fine needle aspiration cytology showed fungal hyphae, morphologically suggestive of Aspergillus, which was later confirmed on histopathology. Aspiration cytology thus plays a crucial role in the early and definitive diagnosis of fungal sinusitis in cases clinico-radiologically suspected of malignancy. An early diagnosis will help the clinician for early and appropriate management and follow-up in order to decrease the high morbidity and mortality associated with it.

Objective The primary objective of this pilot study was to define the change in productivity costs following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Secondary objectives were to identify CRS-related characteristics that may influence the degree of productivity improvement after ESS. Study Design Prospective, multi-institutional, observational cohort study. Methods The human capital approach was used to define productivity costs. Annual absenteeism, presenteeism, and lost leisure time was quantified to define annual lost productive time (LPT). LPT was monetized using the annual daily wage rates obtained from the 2012 US National Census and the 2013 US Department of Labor statistics. Results 27 patients with refractory CRS who underwent ESS were followed for a mean of 15 [SD 4.0] months (range: 8 – 25 months). Following ESS, there were improvements in annual absenteeism (22 days reduced to 3 days), annual presenteeism (41 days reduced to 19 days), and annual household days lost (12 days reduced to 6 days). Overall, the preoperative productivity costs were reduced after ESS, $9,097 vs. $3,301, respectively (pproductivity is negatively impacted by the presence of CRS. The outcomes from this study provide the first insights into the reduced productivity costs associated with receiving ESS for refractory CRS. Future studies with larger sample sizes will need to validate the results from this pilot study. PMID:26371457

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

Pilonidal Sinus of the Glans Penis Associated with Actinomyces Case Reports and Review of Literature

Directory of Open Access Journals (Sweden)

Shylashree Chikkamuniyappa

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.

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

Anatomical Variations of Carotid Artery and Optic Nerve in Sphenoid Sinus Using Computerized Tomographic Imaging

Directory of Open Access Journals (Sweden)

Nikakhlagh

2014-12-01

Full Text Available Background Sphenoid sinus is surrounded by many vital vascular and nervous structures. In more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. Besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. Therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its proximity for nasal endoscopy, sinus surgeries and neurosurgeries. Objectives The aim of this study was to study sphenoid sinus proximity with carotid artery and the optic nerve using computerized tomographic imaging. Materials and Methods In this prospective study, computerized tomographic images of sphenoid sinus of patients referred to Imam Khomeini and Apadana hospitals were studied. The images were studied regarding any bulging, as well as not having a bone covering in sphenoid sinus regarding internal carotid artery and optic nerve. Furthermore, unilateralness or bilateralness of their relationships was studied. Results Among 468 coronal and axial CT scan images of sphenoid sinus, 365 (78% showed post-sellar pneumatization and 103 (22% pre-sellar pneumatization. Regarding existence of internal septa, 346 (74% cases showed multiple septation, and the remaining images were reported to have a single septum. According to the reports of CT scan images, the existence of bulging as a result of internal carotid artery and uncovered artery were 4.22% and 5.8% in the right sinus, 4.9% and 5.4% in the left sinus, and 4.34% and 4.6% in both sinuses, respectively. According to the reports of CT scan images, existence of bulging as a result of optic nerve and uncovered nerve were 5.7% and 4.3% in the right sinus, 6% and 5.4% in the left sinus, and 12% and 3.2% in both sinuses, respectively. Conclusions Due to variability of sphenoid sinus pneumatization and the separator blade of the two sinus cavities, careful attention is required during sinus surgery to avoid

Two hundred consecutive patients referred by otolaryngologists and internists for CT of the paranasal sinuses participated by completing a questionnaire immediately before undergoing CT. Three radiologists blinded to the patients' responses scored the degree of air/fluid level, mucosal thickening, bony reaction, and mucus retention cysts using a graded scale of severity (0 to 3 points). The osteomeatal complexes and nasolacrimal ducts were also evaluated for patency. Bivariate analysis was performed to evaluate the relationship between patients' localized symptoms and CT findings in the respective sinus. One hundred sixty-three patients (82%) reported having some form of facial pain or headache. The right temple/forehead was the most frequently reported region of maximal pain. On CT imaging the maxillary sinus was the most frequently involved sinus. Bivariate analysis failed to show any relationship between patient symptoms and findings on CT. Patients with a normal CT reported a mean 5.88 sites of facial or head pain versus 5.45 sites for patients with an abnormal CT. Patient-based responses of sinonasal pain symptoms fail to correlate with findings in the respective sinuses. CT should therefore be reserved for delineating the anatomy and degree of sinus disease before surgical intervention.

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

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

Global and Multi-National Prevalence of Fungal Diseases—Estimate Precision

Felix Bongomin

2017-10-01

Full Text Available Fungal diseases kill more than 1.5 million and affect over a billion people. However, they are still a neglected topic by public health authorities even though most deaths from fungal diseases are avoidable. Serious fungal infections occur as a consequence of other health problems including asthma, AIDS, cancer, organ transplantation and corticosteroid therapies. Early accurate diagnosis allows prompt antifungal therapy; however this is often delayed or unavailable leading to death, serious chronic illness or blindness. Recent global estimates have found 3,000,000 cases of chronic pulmonary aspergillosis, ~223,100 cases of cryptococcal meningitis complicating HIV/AIDS, ~700,000 cases of invasive candidiasis, ~500,000 cases of Pneumocystis jirovecii pneumonia, ~250,000 cases of invasive aspergillosis, ~100,000 cases of disseminated histoplasmosis, over 10,000,000 cases of fungal asthma and ~1,000,000 cases of fungal keratitis occur annually. Since 2013, the Leading International Fungal Education (LIFE portal has facilitated the estimation of the burden of serious fungal infections country by country for over 5.7 billion people (>80% of the world’s population. These studies have shown differences in the global burden between countries, within regions of the same country and between at risk populations. Here we interrogate the accuracy of these fungal infection burden estimates in the 43 published papers within the LIFE initiative.

Efficacy of endoscopic sinus surgery in the treatment of chronic rhinosinusitis

Directory of Open Access Journals (Sweden)

Basílio, Flávia Machado Alves

2010-12-01

Full Text Available Introduction: The endoscopic sinus surgery (FESS is currently regarded as the gold standard in the treatment of chronic rhinosinusitis (RNSC, with or without nasal polyposis refractory to medical therapy optimized. Objective: To evaluate the improvement of symptoms after FESS RNSC, through a questionnaire. Method: This is a prospective study, which included 34 patients undergoing FESS during the year 2009, the Service of Otorhinolaryngology, Hospital das Clínicas / UFPR. Of these, 22 were diagnosed as RNSC RNSC and 12 had associated nasal polyps. All patients underwent a questionnaire on preoperative symptoms, comorbidities and degree of symptom improvement after surgery, six months after the procedure. Results: The percentage improvement of symptoms more prevalent in the group with RNSC was as follows: nasal obstruction 87.4%, 80.5% headache, pain / facial pressure 91.6% 81.2% posterior nasal discharge. In the group with polyposis associated improvement was nasal obstruction 76.6%, 76.6% posterior nasal discharge, hyposmia, 68.7%, headache 83%. In our study we found an overall improvement in symptoms of 83.74% in patients with RNSC and 80.5% in patients with associated nasal polyposis. Conclusion: FESS is highly effective in controlling symptoms of RNSC with or without polyposis and is, in our study, its efficacy similar to that found in the literature. With respect to patients with nasal polyposis, studies are needed with longer follow up, since this disease has a high degree of recurrence.

The silent sinus syndrome (SSS) is a rare clinical entity characterized by painless spontaneous enophthalmos, hypoglobus, and facial deformities secondary to chronic maxillary sinus atelectasis. The aim of this study was to present an SSS diagnostic feature and evaluate the relationship between nasal septum deviation and maxillary sinus volume. A retrospective chart review of the clinical characteristics of 20 patients diagnosed with SSS between January 2013 and July 2014 were analyzed by the Department of Otorhinolaryngology of University Hospital Complex of Santiago de Compostela. 14 patients were females and six males. The mean age was 43 years (range 28-67 years). The right maxillary sinus was involved in 12 patients and the left maxillary sinus in eight patients. There was no statistical difference between gender and the presence of SSS. Maxillary sinus sizes were significantly smaller on the same side as the deviation (p craneo-caudal photographs. The present study demonstrates that, in adult patients, SSS generally presents a septal deviation to the affected maxillary sinus. We recommend performing a paranasal sinus CT scan when the patient has a deviated nasal septum, retraction of the malar eminence (evidenced from the viewpoint cranio-caudal facial) and hypoglobus. FESS performing postero-anterior uncinectomy and enlargement of the maxillary ostium is recommended to restore sinus pressure and prevent progression of the enophthalmos, hypoglobus and facial deformities.

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

A case report of incidental finding of fungus ball on CBCT of maxillary sinus in treatment planning of dental implant

International Nuclear Information System (INIS)

Lee, Byung Do

2010-01-01

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.

Chronic rhinosinusitis (CRS) is an inflammation of the nose and paranasal sinuses lasting for ≥12 weeks. Endoscopic sinus surgery (ESS) is considered during difficult to treat CRS. The minimally invasive technique focuses on the transition areas rather than on the ostia. The aim of this study was to evaluate symptoms, the number of acute sinusitis episodes, and satisfaction after ESS with either preservation or enlargement of the maxillary sinus ostium. Thirty patients with moderate nonpolypous CRS were enrolled. Uncinectomy only and additional middle meatal antrostomy were randomized for each side of each patient and performed single blindly. The symptoms questionnaires were filled at four time intervals. Significant symptom reduction was achieved independently of operation technique. The number of acute sinusitis episodes indicating the exacerbation rate decreased significantly at 9 and, on average, 68 months postoperatively. However, the exacerbation rate began to increase after 9 months postoperatively. Three revisions were performed on the side with uncinectomy only and one on the side with additional antrostomy. Most patients reported good satisfaction with both procedures. There was a trend for patients with asthma and/or job exposure to report insignificantly more frequently no satisfaction with surgery, especially with the uncinectomy-only procedure. Both procedures seem to be efficient in providing symptom relief and satisfaction. More studies are needed to evaluate if patients with risk factors benefit more from an ostium-enlarging procedure.

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

In previous studies, it has been shown that silk fibroin–nano silver solution can eliminate S. aureus biofilms in vitro, which suggests a potential role of this novel agent in the treatment of biofilm-associated diseases, such as sinusitis.Objective: The aim of this study was to investigate the efficacy of silk fibroin–nano silver solution as a topical anti-biofilm agent in a rabbit model of sinusitis.Methods: Biofilm-associated sinusitis models were established in 24 New Zealand White rabbits by gelatin sponge placement and S. aureus inoculation through a hole drilled into the anterolateral wall of the right maxillary sinus. After 4 weeks, indwelling catheters were placed into the maxillary sinus. Different concentrations of silk fibroin–nano silver solution or normal saline were irrigated slowly into the maxillary sinus via the indwelling catheters. After 7 days of irrigation, the rabbits were sacrificed. The sinus mucosa was harvested and examined for biofilm biomass as well as morphological integrity of the epithelium by scanning electron microscopy.Results: Silk fibroin–nano silver solution was found to be most effective in reducing the biomass of the S. aureus biofilms at a concentration of 384 mg/L, followed by the concentration of 153.6 mg/L, when compared with saline. After treatment with 384 mg/L silk fibroin–nano silver solution, the biofilms were completely

To develop a system for automatically controlling carotid sinus pressure in the study on baroreceptors. The preparation containing carotid sinus with parts of the connected vessels and carotid sinus nerve (CS-CSN) were isolated and perfused. A critical pressure controlling component (PRE-U, Hoerbiger, Deutschland) dictated by a computer was integrated into the system to clamp the intrasinus pressure. The pressure command and the relevant intrasinus pressure were compared to evaluate the validity of the pressure controlling system. A variety of sinus pressure-controlling patterns, including pulsation, ramp and step pressures, could be achieved accurately by using the system, and the pressure-dependent discharge activities of sinus nerve were confirmed. This system for clamping carotid sinus pressure could realize multiple pressure-controlling patterns and is a useful and flexible pressure controlling method that could applied in the study on mechano-electric transduction of baroreceptors.

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

To evaluate the prevalence of the opacification of paranasal sinuses and to correlate the prevalence and severity of the sinus opacification with presence of upper respiratory infection (URI) in infants and children using CT. We analyzed CT scans of 162 children aged under 16 who have no signs and symptoms of paranasal sinusitis. Both sides of maxillary and ethmoidal sinuses were evaluated. We scored from 0 to 3 according to the degree of soft tissue opacification of each sinus and then summed up the scores of each sinus. We divided the children into 5 groups according to their age. We paid particular attention to the following respects: 1) the prevalence of the opacification of the paranasal sinuses in each group; 2) the difference in the prevalence between the children with and without URI; 3) the correlation between the severity of the sinus opacification and the presence of URI. Of 162 children, one or more paranasal sinus opacification was noted in 76(47%): 31(65%) less than 1 year old; 11(52%) between 1 and 2 years old; 16(53%) between 2 and 6 years old; 15(28%) between 6 and 12 years old; and 3(33%) above 12 years old. In children less than 1 year old, no significant difference in the prevalence of the sinus opacification was found between URI-positive(71%) and URI-negative(58%) subgroups. In children between 1 and 12 years old, although the prevalence of the sinus opacification in URI-positive subgroups was much greater than that in URI-negative subgroup, statistically significant difference was noted only in children between 2 and 6 years old. As to the correlation between the severity of the sinus opacification and the presence of URI, these was a statistically significant difference in children between 2 and 6 years old and between 6 and 12 years old. Although the exact pathophysiology is not fully understood, the opacification of the paranasal sinuses is not an uncommon finding at CT in children without the signs and symptoms of sinusitis. We thick that

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.

Maxillary sinus augmentation

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

A rare case of vestibular sinus tract: A periodontist enigma

Directory of Open Access Journals (Sweden)

Disha Nagpal

2016-01-01

Full Text Available Sinus tract occurs commonly in teeth with periapical/periodontal infection but the formation of a vestibular opening, causing esthetic compromise and food lodgement, is uncommon. Definitive treatment of a chronic sinus tract requires treatment of the original problem, that is, the necrotic pulp treated by endodontic therapy or by extraction of the tooth. However, at times endodontic therapy may not be adequate necessitating periodontal intervention. The present case had vestibular opening communicating with root canal of concerned tooth appearing ten years after trauma. The diagnosis of such cases can only be made after careful evaluation and the treatment plan has to be modified from the conventional. The success of such cases depends on the regular follow up as presented here and careful observation after each phase of treatment.

This histobacteriologic study described the pattern of intraradicular and extraradicular infections in teeth with sinus tracts and chronic apical abscesses. The material comprised biopsy specimens from 24 (8 untreated and 16 treated) roots of teeth associated with apical periodontitis and a sinus tract. Specimens were obtained by periradicular surgery or extraction and were processed for histobacteriologic and histopathologic methods. Bacteria were found in the apical root canal system of all specimens, in the main root canal (22 teeth) and within ramifications (17 teeth). Four cases showed no extraradicular infection. Extraradicular bacteria occurred as a biofilm attached to the outer root surface in 17 teeth (5 untreated and 12 treated teeth), as actinomycotic colonies in 2 lesions, and as planktonic cells in 2 lesions. Extraradicular calculus formation (mineralized biofilm) was evident in 10 teeth. Teeth with chronic apical abscesses and sinus tracts showed a very complex infectious pattern in the apical root canal system and periapical lesion, with a predominance of biofilms.

Endoscopic sinus surgery (ESS) enjoys high success rates, but repopulation with pathogenic bacteria is 1 of the hallmarks of poorer outcomes. There are many hypothesized sources of repopulating bacteria; however, this process remains largely unexplored. This study examined changes in the sinus microbiome after ESS and medical therapies to identify potential sources for postsurgical microbial repopulation. Samples from the anterior nares, ethmoid sinus, and nasopharynx were taken at the time of surgery from 13 subjects undergoing ESS for chronic rhinosinusitis (CRS). Patients were treated postoperatively with 2 weeks of oral antibiotics and saline rinses. The ethmoid sinus was sampled at 2 and 6 weeks postoperatively; microbiota were characterized using quantitative polymerase chain reaction (qPCR) and 16S ribosomal RNA (rRNA) gene sequencing. The Morisita-Horn beta-diversity index (M-H) was used to compare similarity between samples. The bacterial burden of the ethmoid was higher 2 weeks postoperatively than 6 weeks postoperatively (p = 0.01). The 6-week samples most closely represented the anterior nares and ethmoid at surgery (M-H = 0.58 and 0.59, respectively), and were least similar to the nasopharynx (M-H = 0.28). Principal coordinates analysis (PCoA) plots illustrate that the ethmoid microbiota temporarily shifted after surgery and antibiotics but returned toward baseline in many subjects. Bacterial communities colonizing the ethmoid 6 weeks postoperatively were most similar to anterior nasal cavity and pretreatment sinus microbial profiles, indicating a high degree of resilience in the sinonasal microbiome of most subjects. Interestingly, surgery and postoperative antibiotic therapy does not appear to reduce bacterial burden, but rather, shifts the microbial consortia. © 2015 ARS-AAOA, LLC.

Atopic patients with chronic obstructive pulmonary disease (COPD) demonstrate more severe symptoms than their non-atopic counterparts. Also, Aspergillus hypersensitivity is known in COPD. However, allergic sensitisation to non-Aspergillus fungi has never been studied in COPD patients. To evaluate the prevalence of fungal sensitisation and its impact on the clinical presentation and outcome of COPD patients. Sensitisation to 17 fungi was studied in 55 COPD patients through skin prick tests, fungus-specific IgE, precipitating antibodies, total IgE and eosinophil counts. The clinical symptoms of patients were monitored thorough a patient-administered questionnaire. Overall, 5.4% (n = 3) of COPD patients were fungus sensitive. The sensitisation was noted to Alternaria alternata and Schizophyllum commune in two patients each, whereas another was sensitive to A. tamarii, Rhizopus spp. and Aspergillus fumigatus. Eosinophils were higher in fungus-sensitised patients (P = 0.001 vs. 0.003). No differences were noted in the clinical presentation of patients sensitised to fungi compared to those not sensitised to fungi or non-atopic. Although low, fungal sensitisation occurs in COPD but it is not limited to Aspergilli alone. Fungus-sensitised patients exhibit greater eosinophilia, implying more severe inflammation. Thus, such patients should be followed up regularly to recognise clinical worsening or development of ABPM. © 2015 Blackwell Verlag GmbH.

The pathomechanism of chronic rhinosinusitis with nasal polyposis (CRS/NP) seems to be unclear. Bacterial-, fungal- and combined biofilms might play a potential role in the pathogenesis of various inflammatory diseases and recently in CRS/NP. A prospective, blinded observational study was performed to confirm that the combination of conventional hematoxylin-eosin (HE) and Gram staining protocols could be used to detect bacterial and fungal biofilms in patients with CRS/NP. A total of 50 patients with CRS/NP undergoing endoscopic sinus surgery (ESS) were analyzed. The negative control group consisted of 12 patients undergoing septoplasty for nasal obstruction without CRS/NP. The nasal polyps and inferior turbinate mucosa specimens applied as negative controls were processed to HE and Gram staining. Biofilm was detected in 44 of 50 patients with CRS/NP and in none of 12 negative controls. In our series, HE method showed an obvious correlation with the results of Gram staining and was allocated to be a good predictor of biofilm existence. It was found that the microscopic structure and thickness of biofilms were strongly associated with the integrity of nasal mucosa and with the characteristics of subepithelial cellular infiltration. This study confirmed the presence of bacterial and fungal biofilms on the surface of NPs obtained from patients with CRS. Since biofilms may affect the severity and recurrence rate of CRS treated by ESS they should be detected histologically. In conclusion, HE staining combined with Gram protocol is a robust and reliable method for the detection of bacterial and fungal biofilms in CRS/NP.

Karatag, Ozan; Cosar, Murat; Kizildag, Betul; Sen, Halil Murat

2013-01-01

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

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.)

Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group. CT vascular studies of patients with idiopathic intracranial hypertension with pulsatile tinnitus ( n = 42), without pulsatile tinnitus ( n = 37), and controls ( n = 75) were independently reviewed for the presence of severe transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence according to published criteria. The prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence in patients with idiopathic intracranial hypertension with pulsatile tinnitus was compared with that in the nonpulsatile tinnitus idiopathic intracranial hypertension group and the control group. Further comparisons included differing degrees of transverse sinus stenosis (50% and 75%), laterality of transverse sinus stenosis/sigmoid sinus diverticulum/dehiscence, and ipsilateral transverse sinus stenosis combined with sigmoid sinus diverticulum/dehiscence. Severe bilateral transverse sinus stenoses were more frequent in patients with idiopathic intracranial hypertension than in controls ( P tinnitus within the idiopathic intracranial hypertension group. Sigmoid sinus dehiscence (right- or left-sided) was also more common in patients with idiopathic intracranial hypertension compared with controls ( P = .01), but there was no significant association with pulsatile tinnitus within the idiopathic intracranial hypertension group. While our data corroborate previous studies demonstrating increased prevalence of sigmoid sinus diverticulum

Radiology of chronic diseases of the ankle joint

1999-01-01

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

Fungus balls or mycetomas are extramucosal and noninvasive accumulations of degenerating fungal hyphae. In head and neck they may localized most frequently in the paranasal sinuses, especially in the maxillary sinus. These indolent infections are mostly caused by Aspergillus spp. In this article, we present two rare fungus ball cases: one occurring in an automastoidectomy cavity of a temporal bone and the other in a concha bullosa. Typically, both patients admitted with vague symptoms consistent with chronic infection resistant to conventional antibacterial medication.

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

2011-01-01

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

To determine the frontal sinus revision rate after nasal polyposis (NP) surgery including frontal recess clearance (FRC) and middle turbinectomy (MT), to search for predictive factors and to analyse surgical management. Longitudinal analysis of 153 patients who consecutively underwent bilateral sphenoethmoidectomy with FRC and MT for NP with a minimum follow-up of 7 years. Decision of revision surgery was made in case of medically refractory chronic frontal sinusitis or frontal mucocele. Univariate and multivariate analysis incorporating clinical and radiological variables were performed. The frontal sinus revision rate was 6.5% (10/153). The mean time between the initial procedure and revision surgery was 3 years, 10 months. Osteitis around the frontal sinus outflow tract (FSOT) was associated with a higher risk of frontal sinus revision surgery (p=0.01). Asthma and aspirin intolerance did not increase the risk, as well as frontal sinus ostium diameter or residual frontoethmoid cells. Among revised patients, 60% required multiple procedures and 70% required frontal sinus ostium enlargement. Our long-term study reports that NP surgery including FRC and MT is associated with a low frontal sinus revision rate (6.5%). Patients developing osteitis around the FSOT have a higher risk of frontal sinus revision surgery. As mucosal damage can lead to osteitis, FSOT mucosa should be preserved during initial NP surgery. However, as multiple procedures are common among NP patients requiring frontal sinus revision, frontal sinus ostium enlargement should be considered during first revision in the hope of reducing the need of further revisions.

Aliouat-Denis, Cécile-Marie; Chabé, Magali; Delhaes, Laurence; Dei-Cas, Eduardo

2014-01-01

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).

Badiane, Aida S; Ndiaye, Daouda; Denning, David W

2015-10-01

Senegal has a high rate of tuberculosis and a low HIV seropositivity rate and aspergilloma, life-threatening fungal infections, dermatophytosis and mycetoma have been reported in this study. All published epidemiology papers reporting fungal infection rates from Senegal were identified. Where no data existed, we used specific populations at risk and fungal infection frequencies in each to estimate national incidence or prevalence. The results show that tinea capitis is common being found in 25% of children, ~1.5 million. About 191,000 Senegalese women get recurrent vaginal thrush, ≥4 times annually. We estimate 685 incident cases of chronic pulmonary aspergillosis (CPA) following TB and prevalence of 2160 cases. Asthma prevalence in adults varies from 3.2% to 8.2% (mean 5%); 9976 adults have allergic bronchopulmonary aspergillosis (ABPA) and 13,168 have severe asthma with fungal sensitisation (SAFS). Of the 59,000 estimated HIV-positive patients, 366 develop cryptococcal meningitis; 1149 develop Pneumocystis pneumonia and 1946 develop oesophageal candidiasis, in which oral candidiasis (53%) and dermatophytosis (16%) are common. Since 2008-2010, 113 cases of mycetoma were diagnosed. In conclusion, we estimate that 1,743,507 (12.5%) people in Senegal suffer from a fungal infection, excluding oral candidiasis, fungal keratitis, invasive candidiasis or aspergillosis. Diagnostic and treatment deficiencies should be rectified to allow epidemiological studies. © 2015 Blackwell Verlag GmbH.

Ukraine has high rates of TB, AIDS and cancer. We estimated the burden of fungal disease from epidemiology papers and specific populations at risk and fungal infection frequencies. HIV/AIDS cases and deaths (2012) and tuberculosis statistics were obtained from the State Service of Ukraine, while chronic obstructive pulmonary disease (COPD) cases were from M. Miravitlles et al., Thorax 64, 863-868 (2009). Annual estimates are 893,579 Ukrainian women get recurrent vaginal thrush (≥4× per year), 50,847 cases of oral candidiasis and 13,727 cases of oesophageal candidiasis in HIV, and 101 (1%) of 10,085 new AIDS cases develop cryptococcal meningitis, 6152 cases of Pneumocystis pneumonia (13.5 cases per 100,000). Of the 29,265 cases of active respiratory TB in 2012, it is estimated that 2881 new cases of chronic pulmonary aspergillosis (CPA) occurred and that the 5-year period prevalence is 7724 cases with a total CPA burden of 10,054 cases. Assuming adult asthma prevalence is ~2.9%, 28,447 patients with allergic bronchopulmonary aspergillosis (ABPA) are likely and 37,491 with severe asthma with fungal sensitisation. We estimate 2278 cases and 376 postsurgical intra-abdominal Candida infections. Invasive aspergillosis in immunocompromised patients is estimated at 303 patients annually; 930 cases in COPD patients. Ninety cases of mucormycosis (2 per 1,000,000) are estimated. In total, ~1,000,000 (2.2%) people in Ukraine develop serious fungal infections annually. © 2015 Blackwell Verlag GmbH.

The aim of this study was to assess the presence of an occipital sinus in both children and adults, and to detail its main associated anatomical characteristics. One hundred of patients' MRI (3D T1 EG) between 0 and 86 years old were studied, in sagittal and axial sections, with the software DxMM. Occipital sinus length, perimeter, and cerebellar falx length measurements were performed with the software's tools. Forty-three percent of patients had an occipital sinus (average perimeter was 3.02 mm, average length was 19.85 mm), and 23.26% of these patients had a cerebellar falx, 30.23% of these patients had one vein or more draining into the occipital sinus. Sixty-two percent of children had an occipital sinus (average perimeter was 2.87 mm, average length was 21.63 mm), and 29.03% of them had a cerebellar falx. Twenty-four percent of adults had an occipital sinus (average perimeter was 3.4mm, average length was 15.28 mm), and 8.33% of them had a cerebellar falx. This work highlights a link between the age and the occipital sinus existence. The perimeter of this sinus seems to be superior for adults, but its length seems to be superior for children. A cerebellar falx with the occipital sinus was found more frequently for children. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Innovation represents a core value of the American Rhinologic Society (ARS), with multiple efforts to promote research in the advancement rhinologic care. We therefore sought to identify trends in extramural sinusitis funding and underutilized sources of support to facilitate future efforts. A systematic review of the National Institutes of Health (NIH) Research Portfolio Online Tools (RePORTER) database (fiscal year 1993 to 2017) was completed with the search strategy: ("chronic sinusitis" OR rhinosinusitis). All identified studies were accepted for review, with comparison to ARS membership rolls to identify studies supported by ARS investigators. Foundation awards were surveyed to identify and characterize additional sources of support. The systematic review identified 958 projects receiving NIH funding, of which 120 remain active. The percentage of sinusitis-related awards and total funding relative to all NIH awards increased over the past 10 years (2006 to 2016) from 0.06% (8 / 9128) and 0.09% ($2,151,152 / $3,358,338,602) to 0.87% (86 / 9540) and 0.90% ($37,201,095 / $4,300,145,614). Among active studies, 9 investigators maintain membership in the ARS and serve as principal investigator or project leader in 12 (10%) studies. ARS investigators received the greatest number of awards from the National Institute on Deafness and Other Communication Disrders (n = 8,66.7%), while only receiving 2.2% of awarded funding from the National Institute of Allergy and Infectious Diseases ($607,500/$26,873,022), the largest source of awards for sinusitis research. Support for sinusitis research is significantly growing, with the largest source of active funding not being fully utilized by members of the ARS. Further efforts to promote funding priorities among extramural sources is necessary to facilitate increased funding for ARS member initiatives. © 2017 ARS-AAOA, LLC.

MR diagnosis of dural sinus thrombosis. Diagnostico por RM de las trombosis de senos durales

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)

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

Bacterial biofilms are a major obstacle in management of recalcitrant chronic rhinosinusitis. NVC-422 is a potent, fast-acting, broad-spectrum, nonantibiotic, antimicrobial with a new mechanism of action effective against biofilm bacteria in in vitro conditions. The aim of this study was to investigate the safety and efficacy of NVC-422 as local antibiofilm treatment in a sheep model of rhinosinusitis. After accessing and occluding frontal sinus ostia in 24 merino sheep via staged endoscopic procedures, S. aureus clinical isolate was instilled in frontal sinuses. Following biofilm formation, ostial obstruction was removed and sinuses irrigated with 0.1% and 0.5% NVC-422 in 5 mM acetate isotonic saline at pH 4.0. Sheep were monitored for adverse effects and euthanized 24 hours after treatment. Frontal sinuses were assessed for infection and changes in mucosa after the treatment. S. aureus biofilms were identified with Baclight-confocal scanning microscopy protocol and the biofilm biomass assayed by applying the COMSTAT2 program to recorded image stacks. After 2 irrigations with 0.1% NVC-422, S. aureus biofilm biomass was reduced when compared to control sinuses (p = 0.0001), though this effect was variable in samples. NVC-422 0.5% solution irrigations reduced biofilm even more significantly and consistently over all samples (p biofilm biomass (p biofilms, with dose-dependent efficacy in this animal model of biofilm-associated sinusitis.

Full Text Available Objective: To estimate the burden of fungal infections in Jordan for the first time. Material and Methods: Population data was from UN 2011 statistics and TB cases from WHO in 2012. Fewer than 100 patients with HIV were recorded in Jordan in 2013. Approximately 100 renal transplants and eight liver transplants are performed annually. There were 12,233 major surgical procedures in Jordan in 2013, of which 5.3% were major abdominal surgeries; candidemia was estimated in 5% of the population based on other countries, with 33% occurring in the ICU. Candida peritonitis/intra-abdominal candidiasis was estimated to affect 50% of the number of ICU candidemia cases. No adult asthma rates have been recorded for Jordan, so the rate from the Holy Land (8.54% clinical asthma from To et al. has been used. There are an estimated 49,607 chronic obstructive pulmonary disease (COPD patients in Jordan, with 64% symptomatic, 25% Gold stage 3% or 4%, and 7% (3472 are assumed to be admitted to hospital each year. No cystic fibrosis cases have been recorded. Literature searches on fungal infections revealed few data and no prevalence data on fungal keratitis or tinea capitis, even though tinea capitis comprised 34% of patients with dermatophytoses in Jordan. Results: Jordan has 6.3 million inhabitants (65% adults, 6% are >60 years old. The current burden of serious fungal infections in Jordan was estimated to affect ~119,000 patients (1.9%, not including any cutaneous fungal infections. Candidemia was estimated at 316 cases and invasive aspergillosis in leukemia, transplant, and COPD patients at 84 cases. Chronic pulmonary aspergillosis prevalence was estimated to affect 36 post-TB patients, and 175 in total. Allergic bronchopulmonary aspergillosis (ABPA and severe asthma with fungal sensitization (SAFS prevalence in adults with asthma were estimated at 8900 and 11,748 patients. Recurrent vulvovaginal candidiasis was estimated to affect 97,804 patients, using a 6

Fat density in the dural sinus on computed tomography (CT) is described in eight cases. Of the eight cases, five had fat deposit in the torcular Herophili, and three in the superior sagittal sinus. This finding was incidentally found by CT and there was no common underlying disease in these cases. It is suggested that this finding represents normal adipose tissue in the dural sinus. (orig.)

Balloons for catheter dilation of paranasal sinuses were introduced in 2005, allowing sinus surgery to be safely performed either in the operating room or the office care setting, under local anesthesia. This change in care setting has raised concerns of overuse or expanded indications for sinus surgery. This study was thus designed to evaluate changes in surgical volumes in the United States, for the period 2006–2011, and to evaluate the impact of the sinus balloons on surgical practice. Methods: The MarketScan® Commercial Claims and Encounter Database was queried for the period 2006 to 2011 using CRS International Classification of Diseases, Ninth Revision codes (473.X and sinus surgery US-based Common Procedural Terminology (CPT codes (endoscopic sinus surgery: CPT codes 31254–31294 and 31299; balloon catheter dilation: CPT codes 31295–31297. MarketScan's projection methodology was applied to estimate the nationwide prevalence of CRS and the incidence of sinus surgery. Procedural case mix and total average payment per surgery were analyzed. Results: From 2006 to 2011, the yearly prevalence of CRS and sinus surgery volume remained flat with ~430 patients with CRS per 100,000 in the employer-sponsored insured population, of which ~117/100,000 underwent surgery. In 2006, 2.69 paranasal sinuses (95% confidence interval [95% CI]: 2.65–2.71 were treated during each individual sinus surgery, with an additional 1.11 nasal procedures (95% CI: 1.08–1.13 performed concurrently.

Miller, D L; Doppman, J L

Bilateral simultaneous sampling of the inferior petrosal sinuses is an extremely sensitive, specific, and accurate test for diagnosing Cushing disease and distinguishing between that entity and the ectopic ACTH syndrome. It is also valuable for lateralizing small hormone-producing adenomas within the pituitary gland. The inferior petrosal sinuses connect the cavernous sinuses with the ipsilateral internal jugular veins. The anatomy of the anastomoses between the inferior petrosal sinus, the internal jugular vein, and the venous plexuses at the base of the skull varies, but it is almost always possible to catheterize the inferior petrosal sinus. In addition, variations in size and anatomy are often present between the two inferior petrosal sinuses in a patient. Advance preparation is required for petrosal sinus sampling. Teamwork is a critical element, and each member of the staff should know what he or she will be doing during the procedure. The samples must be properly labeled, processed, and stored. Specific needles, guide wires, and catheters are recommended for this procedure. The procedure is performed with specific attention to the three areas of potential technical difficulty: catheterization of the common femoral veins, crossing the valve at the base of the left internal jugular vein, and selective catheterization of the inferior petrosal sinuses. There are specific methods for dealing with each of these areas. The sine qua non of correct catheter position in the inferior petrosal sinus is demonstration of reflux of contrast material into the ipsilateral cavernous sinus. Images must always be obtained to document correct catheter position. Special attention must be paid to two points to prevent potential complications: The patient must be given an adequate dose of heparin, and injection of contrast material into the inferior petrosal sinuses and surrounding veins must be done gently and carefully. When the procedure is performed as outlined, both inferior

[The estimation of clinical efficacy of eurespal in the postoperative period following surgical intervention on paranasal sinuses].

Science.gov (United States)

2011-01-01

The objective of the present study was to estimate the influence of Eurespal (Fenspiride) on the changes of fibrous coating in the nasal cavities, transport function of ciliated epithelium, and dynamics of electrochemical properties of the nasal secretion by means of direct joulemetry following surgical intervention on paranasal sinuses (PNS). The study included 30 patients aged from 18 to 65 years presenting with chronic purulent sinusitis in the phase of exacerbation, polypous rhinosinusitis, and acute pyogenic process in PNS. The results of the study indicate that the use of Eurespal significantly accelerates the recovery of the transport function of intranasal mucociliated epithelium which results in a faster regression of the fibrous coat on intranasal mucosa and mucosal oedema. These changes lead to the improvement of drainage and aeration of the paranasal sinuses.

Visualization of normal pleural sinuses with AMBER

1991-01-01

This paper reports that ventral and dorsal pleural sinuses are frequently better appreciated with advanced modulated beam equalization radiography (AMBER) than with standard chest radiography. The visualization of the sinuses with both techniques was compared and their typical configuration studied. Four hundred patients without known chest disease were evaluated. Two groups of 200 patients were studied with either AMBER or standard chest radiography. Visualization was evaluated by three radiologists using a four-point scale. The shape of the sinus was traced if sufficiently visible. A significantly larger segment of the respective sinuses was seen with the AMBER technique. The dorsal sinus was significantly easier to trace than the ventral. Various sinus configurations were noted. AMBER improves the visibility of the pleural sinuses. Knowledge of their normal configuration is the precondition for correctly diagnosing lesions hitherto frequently overlooked

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

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

Beyond the sniffer: frontal sinuses in Carnivora.

Curtis, Abigail A; Van Valkenburgh, Blaire

2014-11-01

Paranasal sinuses are some of the most poorly understood features of mammalian cranial anatomy. They are highly variable in presence and form among species, but their function is not well understood. The best-supported explanations for the function of sinuses is that they opportunistically fill mechanically unnecessary space, but that in some cases, sinuses in combination with the configuration of the frontal bone may improve skull performance by increasing skull strength and dissipating stresses more evenly. We used CT technology to investigate patterns in frontal sinus size and shape disparity among three families of carnivores: Canidae, Felidae, and Hyaenidae. We provide some of the first quantitative data on sinus morphology for these three families, and employ a novel method to quantify the relationship between three-dimensional sinus shape and skull shape. As expected, frontal sinus size and shape were more strongly correlated with frontal bone size and shape than with the morphology of the skull as a whole. However, sinus morphology was also related to allometric differences among families that are linked to biomechanical function. Our results support the hypothesis that frontal sinuses most often opportunistically fill space that is mechanically unnecessary, and they can facilitate cranial shape changes that reduce stress during feeding. Moreover, we suggest that the ability to form frontal sinuses allows species to modify skull function without compromising the performance of more functionally constrained regions such as the nasal chamber (heat/water conservation, olfaction), and braincase (housing the brain and sensory structures). © 2014 Wiley Periodicals, Inc.

Effects of Low Dose Chronic Radiation and Heavy Metals on Plants and Their Fungal and Virus Infections

A Dmitriev

2009-06-01

Full Text Available The effects of low dose chronic radiation on plant disease resistance and fungal and virus infections have been studied. The results obtained in the 10-km Chernobyl zone demonstrated a decrease in plant disease resistance and appearance of a "new" population of stem rust agents of cereal with a high frequency of more virulent clones. Radionuclide contamination and heavy metals lead to wider virus spread and a higher diversity of virus species. The Chernobyl zone is a territory of enhanced risk and potential threats for the environment. A special type of monitoring of microevolution processes in plant pathogens should provide better understanding of how serious these potential threats are.

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

Purpose: The purpose of this study was to define objective and reproducible standards for the quality of CT images as a function of radiation doses and therapeutic validity. Materials and methods: CT images of the paranasal sinuses of 145 patients (77 female, 68 male; 5-83 years old; mean age, 39.9 years) were classified both subjectively (with a view toward their validity for the planning of functional endoscopic sinus surgery, FESS) and objectively by defining the pixel noise (the standard deviation, STD, of the CT number) in a homogeneous region of interest (ROI), centered on the M. masseter and on the frontal lobe. These measurements were then compared to measurements obtained from scan images of a water-filled Perspex phantom. Results: The pixel noise measured in the phantom images was nearly identical to the respective values on the M. masseter on the patient images. The use of an edge-enhancing reconstruction algorithm and low-dose protocols, with a pixel noise amounting to 70-90 Hounsfield Units (HU), are indicated for children, chronic sinusitis, and septum deviation, while standard protocols, with a pixel noise of 50-70 HU, are recommended for the preoperative planning and postoperative control of FESS. The pixel noise for high-dose protocols is less than 50 HU; nonetheless, such protocols should generally be avoided. Conclusion: The pixel noise measured in a water-filled Perspex phantom is indicative of the clinical potential and image quality of paranasal sinus CT scans. Alternatively, the M. masseter can be chosen as an ROI to measure the pixel noise in order to obtain a rough estimate of the image quality or radiation dose class

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.

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

Guatemala is a developing country in Central America with a high burden of HIV and endemic fungal infections; we attempted to estimate the burden of serious fungal infections for the country. A full literature search was done to identify epidemiology papers reporting fungal infections from Guatemala. We used specific populations at risk and fungal infection frequencies in the population to estimate national rates. The population of Guatemala in 2013 was 15.4 million; 40% were younger than 15 and 6.2% older than 60. There are an estimated 53,000 adults with HIV infection, in 2015, most presenting late. The estimated cases of opportunistic fungal infections were: 705 cases of disseminated histoplasmosis, 408 cases of cryptococcal meningitis, 816 cases of Pneumocystis pneumonia, 16,695 cases of oral candidiasis, and 4,505 cases of esophageal candidiasis. In the general population, an estimated 5,568 adult asthmatics have allergic bronchopulmonary aspergillosis (ABPA) based on a 2.42% prevalence of asthma and a 2.5% ABPA proportion. Amongst 2,452 pulmonary tuberculosis patients, we estimated a prevalence of 495 for chronic pulmonary aspergillosis in this group, and 1,484 for all conditions. An estimated 232,357 cases of recurrent vulvovaginal candidiasis is likely. Overall, 1.7% of the population are affected by these conditions. The true fungal infection burden in Guatemala is unknown. Tools and training for improved diagnosis are needed. Additional research on prevalence is needed to employ public health measures towards treatment and improving the reported data of fungal diseases.

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

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)

Alongside the remarkable advances in medical and invasive therapies for the treatment of ischemic heart disease, an increasing number of patients with advanced coronary artery disease unsuitable for revascularization continue to suffer from angina pectoris despite optimal medical therapy. Patients with chronic angina have poor quality of life and increased levels of anxiety and depression. A considerable number of innovative therapeutic modalities for the treatment of chronic angina have been investigated over the years; however, none of these therapeutic options has become a standard of care, and none are widely utilized. Current treatment options for refractory angina focus on medical therapy and secondary risk factor modification. Interventions to create increased pressure in the coronary sinus may alleviate myocardial ischemia by forcing redistribution of coronary blood flow from the less ischemic subepicardium to the more ischemic subendocardium, thus relieving symptoms of ischemia. Percutaneous, transvenous implantation of a balloon expandable, hourglass-shaped, stainless steel mesh in the coronary sinus to create a fixed focal narrowing and to increase backwards pressure, may serve as a new device-based therapy destined for the treatment of refractory angina pectoris.

Oliveira, Marcela Schmidt B. de

2009-09-01

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.

2009-01-01

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

Comprehensive review on endonasal endoscopic sinus surgery

Weber, Rainer K.; Hosemann, Werner

2015-01-01

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

Ophthalmic comlications of functional endoscopic sinus surgery

Directory of Open Access Journals (Sweden)

Sergey A. Karpishchenko

2017-03-01

Full Text Available Functional endoscopic sinus surgery (FESS is an effective and safe surgical technique, which revolutionized the surgical management of nasal cavity and paranasal sinus diseases. The intimate connection between paranasal sinuses and the orbit places the orbital content at a risk of injury during sinus surgery, especially that of ethmoid sinuses. The orbit, the optic nerve, extraocular muscles and the lacrimal drainage system could be damaged during FESS. The risk of injury correlates to anatomical variations, degree and severity of disease, previous procedure results, and surgical experience. Ophthalmic complications can vary in severity from minor ones, such as localized hematomas, to extremely dangerous, such as optic nerve injury, that could lead to complete blindness. In order to minimize the risk of such complications, it is necessary to consider probable anatomic variations of paranasal sinuses and orbit, which are to be detected by CT scan before surgery.

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

Clinical and diagnostic pathways in pediatric fungal infections

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

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). 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. 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. 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.

Rebecca Sin Mei Lim

2013-01-01

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.

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

1993-01-01

To evaluate the normal development of the paranasal sinuses in children with CT, authors prospectively studied with brain CT scans of 260 children without known sinus disease, ranging image from 7 days to 16 years. Maximal anteroposterior and transverse diameters(mm) and maximal cross- sectional area(mm 2 ) of both sides of the maxillary sinus were measured with the aid of computer device. As to the ethmoidal and spheroidal sinuses, we simply documented the presence of the aplastic ethmoidal sinus and calculated the age-incidence of the spheroidal sinus pneumatization, respectively.There noted three phases in the development of the maxillary sinus. The anteroposterior and transverse diameters of the maxillary sinus increased nearly in parallel. The former was always greater than the latter. In no cases was the edathamil sinus aplastic and almost all sinuses were pneumatized even in infants as early as 7 old days. CT identified the conchal pattern of sphenoidal sinus pneumatization infants as early as 11 days old. Sphenoidal sinus pneumatization was seen in 38% of the children under the age of 1 year, 82% of the children between the age of 1 and 2 years, and almost all children older than 2 years. The anteroposterior and transverse diameters of the maxillary sinus seem to reach the adult size by 8 years of age, and the conchal pattern of sphemoidal sinus pneumatization can be recognized earlier with CT than on the plain radiographs

Myxoid Type of Malignant Fibrous Histiocytoma of the Maxillary Sinus: A Case Report

2011-04-01

Full Text Available Introduction: Myxofibrosarcoma was originally described as the myxoid variant of Malignant Fibrous Histiocytoma (MFH, a high-grade and aggressive sarcoma, which is very uncommon in the head and neck region, with about 100 cases reported up to now. MFH occurring in the maxillary sinus is so rare that only 23 cases have been reported. We hereby report a case of myxofibrosarcoma in the maxillary sinus. Case Report: The case was a 54-year-old male with symptoms of toothache in the right posterior maxillary teeth, a swelling adjacent to maxillary molar region and symptoms of chronic maxillary sinusitis. In clinical examination, the teeth were sensitive to percussion and palpation, but no caries and restoration was detected on his molar teeth. He was suffering from local pain and tenderness over his midface and mild fever, fatigue and some nonspecific vague pain. CT scan showed a mass lesion involving right nasal cavity, maxillary and ethmoidal sinuses. A low-grade malignancy arising from the right maxillary sinus was highly suspected. A surgery was done to remove the mass. The histological and immunohistochemical studies proved the diagnosis of myxoid variant of Malignant Fibrous Histiocytoma. Therefore radiotherapy and chemotherapy was started for the patient but six months later the symptoms returned and CT scan showed a right maxillary and ethmoidal mass that extended to base of the skull. Maxillectomy and ethmoidectomy were performed for the patient, but 2 months later he died because of the extension of the tumor, which confirmed the necessity of early diagnosis. Conclusion: Amplified radical surgery is the first choice of treatment. The second surgery has special value to the recurrent patients. Radiotherapy alone or chemotherapy alone is not effective to MFH of head and neck region

The superior sagittal sinus (SSS) and transverse sinus are the major dural sinuses that receive a considerable amount of venous drainage. The occlusion of them has been suggested to cause intracranial hypertension, hemorrhage, and lead to potentially fatal consequences. We reported a 35-year-old woman with headache presented to our emergency department with a decreased level of consciousness and epileptic seizures. The examination of speech, higher mental function, and cranial nerve were normal. Computed tomography (CT) demonstrated both subarachnoid and intraparenchymal hemorrhage and brain edema at the right temporal lobe accompanied by high density shadow in the right transverse sinus. Digital subtraction angiography (DSA) revealed extensive thrombosis of the SSS and bilateral transverse sinus. The SSS and transverse sinus thrombosis, accompanied by right temporal lobe hemorrhage, subarachnoid hemorrhage (SAH). An emergent mechanical thrombectomy by placed Solitair AB stent in the SSS, respectively, passed left and right sigmoid sinus-transverse sinus route. We removed the most clots, DSA revealed recanalization of the SSS and left transverse sinus was seen with normalization of the venous outflow, the occlusion of right transverse sinus was still present. There were 4 hours after patient back to neurosurgical intensive care unit (NICU), patient appeared anisocoria (R/L:4.0/2.5 mm), bilateral light reflexes disappeared, then we took a CT reexamination revealed intraparenchymal hemorrhage increased, brain edema was aggravated at the left temporal lobe, and mild midline shift. Subsequently, we performed decompressive hemicraniectomy and puncture the hematoma supplemented by B ultrasonic. Anticoagulation treatment was initiated 24 hours after surgery, and follow-up DSA showed gradually improved patency in the SSS and bilateral transverse sinus. Despite occlusion of the SSS and bilateral transverse sinus, patient's symptoms resolved after the operations and he

'Eosinophilic chronic rhinosinusitis (ECRS)' is a newly developed entity of chronic rhinosinusitis, which shows resistance against conventional treatment and poor prognosis. Pathologically, ECRS is manifested by high-degree of eosinophilic infiltration in the paranasal sinus mucosa. We structure the CT diagnostic criteria of ECRS and assess its availability. This diagnostic criteria consists of disease distribution (bilateral and predominant in the ethmoid sinus), existence of nasal polyp (s) and high attenuation which suggestive of allergic mucine. We retrospectively review CT of clinically diagnosed 14 ECRS cases to see if CT features of each case fit the criteria or not. The current CT diagnostic criteria of ECRS were proven to be useful to evaluate cases with clinical suspicion of ECRS. (author)

Sinus of valsalva aneurysm is a rare condition arising from any of the three aortic sinuses. Among them, an aneurysm arising from the left coronary sinus is the rarest. Most of these cases were earlier diagnosed using echocardiography and conventional angiography. But with the availability of advanced imaging modalities like 64 slice cardiac CT and MR modalities, this condition can be accurately assessed noninvasively. We report a case of ruptured aneurysm originating from the left coronary sinus with a long windsock type of fistulous track between the aneurysm and right atrium evaluated by 64 slice cardiac CT imaging. This was later confirmed perioperatively.

In patients affected by carotid sinus hypersensitivity, long-term vasodilator therapy might increase the risk of syncopal episodes by reducing systolic blood pressure and venous return to the heart. Thirty-two patients (mean age 73 +/- 9 years; 20 men) who met all the following criteria were included: (1) one or more episodes of syncope occurring during long-term (>6 months) treatment with angiotensin-converting enzyme inhibitors, long-acting nitrates, calcium antagonists, or a combination of these; (2) a positive response to carotid sinus massage, defined as the reproduction of spontaneous syncope in the presence of ventricular asystole > or =3 seconds or a fall in systolic blood pressure > or =50 mm Hg; (3) negative workup for other causes of syncope. The patients were randomly assigned to continue or to discontinue use of vasodilators; carotid sinus massage was repeated 2 weeks after randomization. By the end of the study period, the baseline values of systolic blood pressure were significantly different between the 2 groups of patients both in supine (P=.01) and upright (P=.03) positions. Syncope had been induced by carotid sinus massage in 81% of patients in the "on-vasodilator" group and in 62% of patients in the "off-vasodilator" group (P=.21). The cardioinhibitory reflex was of similar magnitude in the 2 groups, being found in 50% of the patients in each group, with a maximum ventricular pause of 7.1 +/- 2.7 and 6.7 +/- 1.8 seconds, respectively. The percentage decrease of blood pressure did not differ between the 2 groups, even if, in absolute values, the baseline difference of blood pressure roughly persisted for the duration of the test. In consequence of that, the rise of blood pressure to similar values was delayed approximately 30 seconds in the "on-vasodilator" group and took more than 2 minutes to return to baseline values. In patients affected by carotid sinus hypersensitivity, chronic vasodilator therapy does not have a direct effect on carotid

Accumulating evidence supports a role for inflammation in psychiatric illness, and the onset or exacerbation of psychiatric symptoms may follow non-CNS infections. Here, we provide the first detailed description of obsessive-compulsive and related psychiatric symptoms arising concurrently with sinusitis. We reviewed the charts of 150 consecutive patients evaluated in our Pediatric Acute-onset Neuropsychiatric Syndromes clinic for documented sinusitis as defined by the American Academy of Pediatrics guidelines. Sinusitis treatments, sinonasal imaging, and neuropsychiatric symptoms before, during, and after sinusitis onset were noted. Patients were included in the final review if they had a clear diagnosis of isolated sinusitis (without concurrent illness and/or immunodeficiency), and were evaluated during an episode of sinusitis. 10/150 (6.6%) patients had isolated sinusitis at the time of their neuropsychiatric deterioration. Eight patients received antibiotics to treat sinusitis, three of whom also received sinus surgery. Neuropsychiatric symptoms improved in all eight patients concurrent with resolution of sinusitis per parent report and clinician assessment. One patient did not follow through with recommended sinus surgery or antibiotics and her psychiatric symptoms persisted. One patient was lost to follow-up. Improvement of psychiatric symptoms correlated with resolution of sinus disease in this retrospective study. Identification, treatment, and resolution of underlying infections, including sinusitis, may have the potential to change the trajectory of some neuropsychiatric illnesses. Randomized clinical trials are needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

We obtained the following results by reviewing the radiographic findings of 15 cases of Sinus valsalva rupture who were diagnosed surgically at Seoul National University Hospital since 1979. 1. Among distribution was from 15 years to 40 years with the mean age of 24 years. Among the 15 cases, 9 cases were male and 7 were female. 2. Ruptured sinus is right coronary sinus projecting to right ventricle in all 15 cases. Combined diseases are ventricular septal defect in 12 cases, Aortic Valvular heart disease in 4 cases, and narrowing of right ventricular outflow tract in 2 cases, and aneurysmal dilatation of right pulmonary artery in 1 cases. 3. Chest X-ray findings were that of left to right shunt, i.e, cardiomegaly, increased pulmonary vascularity but were normal in 3 cases. 4. Aortography showed sequential leakage of dye from right coronary sinus to right ventricle and finally to pulmonary artery in 9 cases, and in 9 cases of them the leakage is directly to right ventricular outflow tract without filling of sinus portion of the ventricle., i.e., type I. 5. The leakage was well shown in left ventricular diastolic phase and not shown in systolic phase. 6. Ventricular septal defects were not detected definitely in spite of taking left ventriculography. 7. Cine angiography is essential for detecting accurate site, degree and direction of sinus valsalva rupture and other associated cardiac abnormality.

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

Methods of light, electron microscopy and immunohistochemistry were used to study the samples of maxillary sinus (MS) mucous membrane (MM) under normal conditions and in odontogenic sinusitis. To study the normal structure, the samples were obtained at autopsy from 26 human corpses 12-24 hours after death. Electron microscopic and immunohistochemical study was performed on biopsies of grossly morphologically unchanged MS MM, obtained during the operations for retention cysts in 6 patients. MS MM in perforative sinusitis was studied using the biopsies obtained from 43 patients. The material is broken into 4 groups depending on perforative sinusitis duration. Under normal conditions, MS MM is lined with a pseudostratified columnar ciliated epithelium. Degenerative changes of ciliated epithelial cells were already detected at short time intervals after MS perforations and become apparent due to reduction of specific volume of mitochondria and, rough endoplasmic reticulum, and increase of nuclear-cytoplasmic ratio. In the globlet cells, the reduction of nuclear-cytoplasmic ratio was associated with the disturbance of the secretory product release. At time intervals exceeding 3 months, epithelium underwent metaplasia into simple cuboidal and stratified squamous keratinized, while in MS MM lamina propria, cellular infiltration was increased. CD4+ cell content in sinus MM gradually increased, while at late periods after perforation occurrence it decreased. Low CD4+ cell count within the epithelium and the absence of muromidase on the surface of MS MM was detected. With the increase of the time interval since MS perforation, the number of CD8+ and CD20+ cells in MS MM was found to increase.

Although diseases of the paranasal sinuses have a relatively homogeneous clinical presentation, their causes can vary considerably. Radiological imaging only became relevant in paranasal sinus diagnostics following the introduction of cross-sectional imaging. In addition to technical details on imaging procedures and the individual criteria of the different modalities, anatomic details and congenital variations are presented. Particularly in acute inflammatory diseases as well as traumatic lesions, imaging is essential in preoperative planning and postoperative control. The article gives a detailed description of options in radiologic imaging of the paranasal sinuses. (orig.) [de

Full Text Available Carotid sinus hypersensitivity is a common cause of fainting and falls in the elderly, and can be diagnosed by carotid sinus massage. We present a 67-year-old diabetic man who was admitted with hyperglycemia. During thyroid examination, clouding of consciousness occurred with unilateral palpation. Asystole was documented for 4.8 seconds and suspected for 7 seconds upon carotid sinus massage. A cardioverter defibrillator was implanted. Carotid sinus hypersensitivity should be kept in mind when examining diabetic patients.

Sinusitis is a very common disease and improved diagnostic tools are desirable also in view of reducing over-prescription of antibiotics. A non-intrusive optical technique called GASMAS (GAs in Scattering Media Absorption Spectroscopy), which has a true potential of being developed into an important complement to other means of detection, was utilized in this work. Water vapor in the frontal sinuses, related to the free gas volume, was studied at around 937 nm in healthy volunteers. The results show a good stability of the GASMAS signals over extended times for the frontal sinuses for all volunteers, showing promising applicability to detect anomalies due to sinusitis. Measurements were also performed following the application of a decongestion spray. No noticeable signal change was observed, which is consistent with the fact that the water vapor concentration is given by the temperature only, and is not influenced by changes in cavity ventilation. Evaluated GASMAS data recorded on 6 consecutive days show signal stability for the left and right frontal sinus in one of the test volunteers. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Sinus stenosis occasionally occurs in dural arteriovenous fistulas. Sinus stenosis impedes venous outflow and aggravates intracranial hypertension by reversing cortical venous drainage. This study aimed to analyze the likelihood of sinus stenosis and its impact on cerebral hemodynamics of various types of dural arteriovenous fistulas. Forty-three cases of dural arteriovenous fistula in the transverse-sigmoid sinus were reviewed and divided into 3 groups: Cognard type I, type IIa, and types with cortical venous drainage. Sinus stenosis and the double peak sign (occurrence of 2 peaks in the time-density curve of the ipsilateral drainage of the internal jugular vein) in dural arteriovenous fistula were evaluated. "TTP" was defined as the time at which a selected angiographic point reached maximum concentration. TTP of the vein of Labbé, TTP of the ipsilateral normal transverse sinus, trans-fistula time, and trans-stenotic time were compared across the 3 groups. Thirty-six percent of type I, 100% of type IIa, and 84% of types with cortical venous drainage had sinus stenosis. All sinus stenosis cases demonstrated loss of the double peak sign that occurs in dural arteriovenous fistula. Trans-fistula time (2.09 seconds) and trans-stenotic time (0.67 seconds) in types with cortical venous drainage were the most prolonged, followed by those in type IIa and type I. TTP of the vein of Labbé was significantly shorter in types with cortical venous drainage. Six patients with types with cortical venous drainage underwent venoplasty and stent placement, and 4 were downgraded to type IIa. Sinus stenosis indicated dysfunction of venous drainage and is more often encountered in dural arteriovenous fistula with more aggressive types. Venoplasty ameliorates cortical venous drainage in dural arteriovenous fistulas and serves as a bridge treatment to stereotactic radiosurgery in most cases. © 2017 by American Journal of Neuroradiology.

Functional endoscopic sinus surgery (FESS) is nowadays the "gold standard" for frontal sinus pathologies, but management of acute situations and the aproach and/or the extent of the surgery perfomed in the frontal recess remains controversial nowadays. We report our experience in 4 patients with orbital celulitis due to frontal sinusitis who underwent combined external surgery (mini-trephination) and endoscopic sinus surgery. All patients managed sinus patency without any complications. We found this combined sinusotomy as an easy, effective and reproductible technique in order to resolve the difficult surgical management of complicated frontal sinusitis.

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

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

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

Allergic Aspergillus Rhinosinusitis

Full Text Available Allergic fungal rhinosinusitis (AFRS is a unique variety of chronic polypoid rhinosinusitis usually in atopic individuals, characterized by presence of eosinophilic mucin and fungal hyphae in paranasal sinuses without invasion into surrounding mucosa. It has emerged as an important disease involving a large population across the world with geographic variation in incidence and epidemiology. The disease is surrounded by controversies regarding its definition and etiopathogenesis. A working group on “Fungal Sinusitis” under the International Society for Human and Animal Mycology (ISHAM addressed some of those issues, but many questions remain unanswered. The descriptions of “eosinophilic fungal rhinosinusitis” (EFRS, “eosinophilic mucin rhinosinusitis” (EMRS and mucosal invasion by hyphae in few patients have increased the problem to delineate the disease. Various hypotheses exist for etiopathogenesis of AFRS with considerable overlap, though recent extensive studies have made certain in depth understanding. The diagnosis of AFRS is a multi-disciplinary approach including the imaging, histopathology, mycology and immunological investigations. Though there is no uniform management protocol for AFRS, surgical clearing of the sinuses with steroid therapy are commonly practiced. The role of antifungal agents, leukotriene antagonists and immunomodulators is still questionable. The present review covers the controversies, recent advances in pathogenesis, diagnosis, and management of AFRS.

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

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

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

Nosocomial sinusitis is a common complication of patients in ICUs. Its diagnosis is important, and early treatment is required to avoid serious complications such as pneumonia, sepsis, meningitis, and intracranial abscesses. To identify the germs causing sinusitis in ICUs by nasal swabs and maxillary sinus puncture, and to correlate these results. ICU patients with a diagnosis (CT confirmed) of maxillary sinusitis underwent nasal swab and puncture of the sinus to collect material for culture and antibiogram. This study evaluated 22 patients. The microbial agent isolated in the swab correlated with the agent in the puncture in 14 of 22 cases (63%). Gram-negative bacteria were the most frequent, as follows: Pseudomonas aeruginosa (29% of punctures), following by Proteus mirabillis (26%) and Acinetobacter baumanni (14%). The resistance index in the antibiogram was high to antibiotics. Maxillary sinus puncture of ICU patients with sinusitis appears to be the best method for identifying bacteria; antibiograms demonstrate resistance to therapy. The swab has little diagnostic value; the correlation was 63%. It may be used when sinus puncture is contraindicated.

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

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

Full Text Available A case of chronic sphenoidal sinusitis in a girl of 9 years old is proposed; in clinical picture oculomotor dysfunction occurred (ptosis, strabismus divergent, diplopia, epiphora. The condition was masked by neurological symptoms, and so initial differential diagnosis was between 1 ocular form of myopathy (including mitochondrial diseases, 2 ocular form of myasthenia and 3 onset of multiple sclerosis. The definite diagnosis «pansinusitis» was proposed by neurologist only after attentive analysis of clinical symptoms and data of MRI, only since 1,5 year after beginning of the disease. This clinical case demonstrates the complexity of differential diagnosis of chronic sphenoidal sinusitis in children and necessity of developed clinical thinking for a doctor of every speciality

Characterize indications, perioperative considerations, clinical outcomes and complications for concurrent endoscopic sinus surgery (ESS) and rhinoplasty. Chronic rhinosinusitis and septal deviation with or without inferior turbinate hypertrophy independently impair patient-reported quality of life. Guidelines implore surgeons to include endoscopy to accurately evaluate patient symptoms. Complication rates parallel those of either surgery (ESS and rhinoplasty) alone and are not increased when performed concurrently. Operative time is generally longer for joint surgeries. Patient satisfaction rates are high. Concurrent functional and/or cosmetic rhinoplasty and ESS is a safe endeavor to perform in a single operative setting and most outcomes data suggest excellent patient outcomes. Additional studies that include patient-reported outcome measures are needed.

2016-10-01

Introduction  Several surgical techniques and modifications have been described to reduce the high recurrence rate after excision of preauricular sinus. Objectives  The aim of this study is to review the literature regarding surgical approaches for preauricular sinus. Data Synthesis  We performed searches in the LILACS, MEDLINE, SciELO, PubMed databases and Cochrane Library in September, 2015, and the key words used in the search were "preauricular sinus," "sinusectomy," "supra-auricular approach," "methylene blue," and/or "recurrence." We revised the results of 17 studies, including 1270 preauricular sinuses that were surgically excised by sinusectomy in 937 ears and by supra-auricular approach in 333 ears. Recurrence with supra-auricular was 4 (1.3%) while sinusectomy was 76 (8.1%) with significant difference ( p  Supra-auricular approach had significantly less recurrence rate than tract sinusectomy approaches. Thus, it could be regularly chosen as the standard procedure for preauricular sinus excision. As such, it would be helpful for surgeons to be familiar with this approach.

In order to find out the validity of the vascular waterfall mechanism in coronary venous circulation, the role of coronary sinus pressure in the regulation of coronary return volume via the coronary sinus is studied in healthy animals. An experimental model of pressure regulation in the coronary sinus was prepared, and aortic pressure, EKG and the cardiac output (measured by thermodilution) were recorded. The return volume via the coronary sinus was measured at coronary sinus pressure of 10 or less, 15, 20, and 25 mmHg or more, for a total of 36 determinations. Increased coronary sinus pressure did not produce significant changes in aortic pressure, heart rate, cardiac index or coronary return volume via coronary sinus. When coronary sinus pressure was 25 mmHg or more, there was a significant decline in the average of coronary return volume via coronary sinus. Nevertheless, stepwise variant regression showed that the coronary sinus pressure per se does not condition the volume of coronary return via the coronary sinus. Our results suggest that in the healthy animals, the vascular waterfall mechanism in coronary venous circulation is not valid. Our results suggest that in the correction of congenital cardiac malformations using atriopulmonary anastomosis procedures, employing techniques that ensure coronary sinus drainage into the left atrium, in order to avoid the hemodynamic repercussions attributable to the vascular waterfall mechanism, is not justified.

The preoperative roentgenmorphology of the nasomaxillary sinuses was compared with the intraoperative findings. The dates of 285 patientes were evaluated. For the maxillary sinus there was correspondency in 85.7%. There were no differences in the cases explored with tomography. For the ethmoidal sinus there was correspondency in 89.5% and for the frontal sinus in 82.7%. The importance of the preoperative roentgenexamination with the standard-exposure in occipitomental projection was less the demonstration of the inflammation than of other findings. The sphenoidal sinus was best explored by tomography. The standardprojection did not always allow the differentiation of cystes, polypes and mucoceles in dieseased sinuses. The tomography was superior to the standardprojection. In tumorpatients the accompanying inflammation could not be separated from tumorinfiltration with certainty. (orig.) [de

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.

Numerous methods to achieve occipitocervical stabilization have been described, including the use of occipital plate/screw constructs. Bicortical screws may increase the pullout strength, but intracranial injuries to venous sinuses have been reported. This study was performed to analyze the variations in occipital sinuses to prevent sinus injury caused by the bicortical screw. Occipital sinuses of 1720 patients were examined using digital subtraction angiography. The data collected included patient age and sex, occipital sinus type, distance between occipital sinus and midline, depth from inion to occipital sinus, and distance between occipital sinus and midline occiput at different levels. The mean age of patients was 57 years ± 13. There were 807 (46.9%) men and 913 (53.1%) women. The most common occipital sinus type was single occipital sinus off-midline (type B2). The least common occipital sinus type was absent occipital sinuses (type A; 8.7% of patients). There was no significant difference between age and occipital sinus type (P = 0.310). Also, the difference between sexes was not significant in regard to occipital sinus type in general. However, in subgroup analysis of type B1 and B2, there was a significant difference between sexes (P occipital sinus was 19.913 mm ± 7.437. The occipital sinus shows several variations, and many morphologic differences can be seen. Preoperative detailed examination by magnetic resonance venography or vertebral angiography may be required for cases in which bicortical occipital screw fixation is necessary to avoid occipital sinus-related complications.

Odontogenic maxillary sinusitis diagnosed using conebeam x-ray CT

International Nuclear Information System (INIS)

Sato, Kiminori

2007-01-01

We evaluated the usefulness of conebeam x-ray CT in the diagnosis of odontogenic maxillary sinusitis in 21 patients. Among teeth causing odontogenic maxillary sinusitis, 95% had apical lesions after root canal treatment. Most root canals were filled with filling materials incompletely. Apical lesions in inappropriately treated teeth thus caused odontogenic maxillary sinusitis. Conebeam CT involves 3-dimensional isotropic voxel image date in up to 512 frames for transaxial, coronal, and sagittal planes, so resolution in imaging on the body axis was especially high. Multiplanar reconstruction and volume rendering images at any optional plane could be obtained without interpolation. The relationship between causative teeth and the maxillary sinus could be observed and measured, and odontogenic maxillary sinusitis accurately diagnosed. In addition to the accurate diagnosis of apical lesions, maxilla, and maxillary sinus, periodontal ligament space, lamina dura, pulp cavity, root canal, canal-treated root, apical periodontitis, alveolar ostitis, marginal periodontitis of causative teeth could be observed. Metal artifacts were minimized, making conebeam CT useful in the diagnosis of periodontal tissue and causative teeth, including root-canal-treated and crown-restored teeth. (author)

Two patients developed cavernous sinus thrombophlebitis from a tooth infection. A 36-year-old man experienced a severe headache with bilateral third and sixth cranial nerve palsies after extraction of his left upper third molar. Another 53-year-old diabetic man developed fever, headache, and bilateral complete ophthalmoplegia after a tooth infection. The brain magnetic resonance imaging scans of both patients showed bilateral cavernous sinus partial thrombosis. Broad-spectrum antibiotics plus low-molecular-weight heparin successfully resolved all symptoms. Both patients recovered fully without any recurrence at the 3-month follow-up visit.

Ibrutinib has revolutionized the management of chronic lymphocytic leukemia and is now being increasingly used. Although considered to be less immunosuppressive than conventional immunochemotherapy, the observation of a few cases of invasive fungal infections in patients treated with ibrutinib prompted us to conduct a retrospective survey. We identified 33 cases of invasive fungal infections in patients receiving ibrutinib alone or in combination. Invasive aspergillosis (IA) was overrepresented (27/33) and was associated with cerebral localizations in 40% of the cases. Remarkably, most cases of invasive fungal infections occurred with a median of 3 months after starting ibrutinib. In 18/33 cases, other conditions that could have contributed to decreased antifungal responses, such as corticosteroids, neutropenia, or combined immunochemotherapy, were present. These observations indicate that ibrutinib may be associated with early-onset invasive fungal infections, in particular IA with frequent cerebral involvement, and that patients on ibrutinib should be closely monitored in particular when other risk factors of fungal infections are present. © 2018 by The American Society of Hematology.

2001-01-01

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

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

Clinical Comparison of Sinus Lift via Summers Osteotomy and Piezosurgery

Directory of Open Access Journals (Sweden)

Mehrdad Radvar

2017-12-01

Full Text Available Introduction: Sinus lift is a process that could be performed by two methods. In the closed sinus lift, hybrid materials enter a suitable position through a created cavity. Afterwards, the materials are pressed without damaging the sinus membrane, and the implants are usually placed at the same time. Closed sinus lift is carried out via osteotomy and piezosurgery, and each of the techniques has certain advantages and limitations. The present study aimed to compare the clinical results of closed sinus lift using the summers osteotomy and piezosurgery. Materials and Methods: In this study, 20 patients requiring dental implants in the posterior segment of the maxilla via sinus lift surgery were randomly divided into two groups. The first group received piezosurgery, and the second group underwent summers osteotomy for sinus lift. Postoperative Schneiderian membrane perforation, inflammation, pain, bone gain, and bone loss were compared between the groups six months after the surgery using Mann-Whitney U test and two-sample t-test. Results: In the groups receiving piezosurgery and summers osteotomy, mean sinus lift was 3.6±0.9 and 4.0±2.2 mm, pain score was 1.1±1.2 and 0.9±0.8, bone gain was 2.2±0.8 and 3.1±1.3 mm, and crestal bone loss was 1.1±1.2 and 0.9±0.8 mm, respectively. Moreover, no Schneiderian membrane perforation was observed in the two methods, and the differences between the groups were not considered significant (P>0.05. Conclusion: According to the results, the clinical outcomes of piezosurgery in sinus lift are similar to those of summers osteotomy. Therefore, piezosurgery could be a proper alternative to summers osteotomy in sinus lift surgery.

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

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. But this kind of sinus

We demonstrate a novel nonintrusive technique based on tunable diode laser absorption spectroscopy to investigate human sinuses in vivo. The technique relies on the fact that free gases have spectral imprints that are about 10.000 times sharper than spectral structures of the surrounding tissue. Two gases are detected; molecular oxygen at 760 nm and water vapor at 935 nm. Light is launched fiber optically into the tissue in close proximity to the particular maxillary sinus under study. When investigating the frontal sinuses, the fiber is positioned onto the caudal part of the frontal bone. Multiply scattered light in both cases is detected externally by a handheld probe. Molecular oxygen is detected in the maxillary sinuses on 11 volunteers, of which one had constantly recurring sinus problems. Significant oxygen absorption imprint differences can be observed between different volunteers and also left-right asymmetries. Water vapor can also be detected, and by normalizing the oxygen signal on the water vapor signal, the sinus oxygen concentration can be assessed. Gas exchange between the sinuses and the nasal cavity is also successfully demonstrated by flushing nitrogen through the nostril. Advantages over current ventilation assessment methods using ionizing radiation are pointed out.

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

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)

[Does CT-navigation improve the outcome of functional endonasal sinus surgery?].

Computer-assisted surgery (CAS) has found widespread use in functional endonasal sinus surgery (FESS) over the past few years. The present study investigates if CAS leads to a better outcome in FESS. All patients who underwent endonasal sphenoethmoidectomy were enrolled in a prospective, non-randomized study. The procedures were done without CAS (group A) in 2003 and in 2004 with CAS (group B), using a Stryker navigation unit. 62 patients (113 sphenoidectomies) were included in group A and 61 patients (109 sphenoidectomies) in group B. The underlying disease was recurrent chronic sinusitis or polyposis nasi in all patients except for inverted papilloma in one patient of group A and in two patients of group B. The follow-up period was 6 months. Preoperatively and at 6 months postoperatively, a CT-scan was obtained and symptom scores were assessed using a questionnaire. No significant difference was found between group A and B with respect to symptom scores, and CT-scans preoperatively and at 6 months postoperatively. The operation strategy did not change by the introduction of CAS. The frontal sinus was entered in group A and B in 59% and 64%, respectively. All parameters significantly improved postoperatively, compared to the preoperative values. As far as complications are concerned, two anterior orbital injuries and one retrobulbar haematoma occurred in group A and one postoperative lacrimal stenosis in group B. CAS does not lead to a better clinical outcome in FESS. Our data suggest that the rate of complications may be reduced using CAS. However, studies with a much larger number of patients would be necessary for a definite answer to this issue.

More than 1·6 million people are estimated to die of fungal diseases each year, and about a billion people have cutaneous fungal infections. Fungal disease diagnosis requires a high level of clinical suspicion and specialised laboratory testing, in addition to culture, histopathology, and imaging expertise. Physicians with varied specialist training might see patients with fungal disease, yet it might remain unrecognised. Antifungal treatment is more complex than treatment for bacterial or most viral infections, and drug interactions are particularly problematic. Health systems linking diagnostic facilities with therapeutic expertise are typically fragmented, with major elements missing in thousands of secondary care and hospital settings globally. In this paper, the last in a Series of eight papers, we describe these limitations and share responses involving a combined health systems and public health framework illustrated through country examples from Mozambique, Kenya, India, and South Africa. We suggest a mainstreaming approach including greater integration of fungal diseases into existing HIV infection, tuberculosis infection, diabetes, chronic respiratory disease, and blindness health programmes; provision of enhanced laboratory capacity to detect fungal diseases with associated surveillance systems; procurement and distribution of low-cost, high-quality antifungal medicines; and concomitant integration of fungal disease into training of the health workforce.

Fungal endocarditis is a rare and fatal condition. The Candida and Aspergillus species are the two most common etiologic fungi found responsible for fungal endocarditis. Fever and changing heart murmur are the most common clinical manifestations. Some patients may have a fever of unknown origin as the onset symptom. The diagnosis of fungal endocarditis is challenging, and diagnosis of prosthetic valve fungal endocarditis is extremely difficult. The optimum antifungal therapy still remains debatable. Treating Candida endocarditis can be difficult because the Candida species can form biofilms on native and prosthetic heart valves. Combined treatment appears superior to monotherapy. Combination of antifungal therapy and surgical debridement might bring about better prognosis.

In Bangladesh there are several published papers on superficial mycoses. Deep mycoses are also recognized as an important emerging problem. Here, we estimate the annual incidence and prevalence of serious fungal infections in Bangladesh. Demographic data were obtained from world population reports and the data on TB and HIV extracted from the online publications on tuberculosis in Bangladesh and Asia Pacific research statistical data information resources AIDS Data HUB. All the published papers on fungal infections in Bangladesh were identified through extensive search of literature. We estimated the number of affected people from populations at risk and local epidemiological data. Bangladesh has a population of ∼162.6 million, 31% children and only 6% over the age of 60 years. The pulmonary TB caseload reported in 2014 was 119,520, and we estimate a prevalence of 30,178 people with chronic pulmonary aspergillosis, 80% attributable to TB. An anticipated 90,262 and 119,146 patients have allergic bronchopulmonary aspergillosis or severe asthma with fungal sensitization. Only 8,000 people are estimated to be HIV-infected, of whom 2900 are not on ART with a CD4 count Bangladesh. Candida bloodstream infection was estimated based on a 5 per 100,000 rate (8100 cases) and invasive aspergillosis based primarily on leukemia and COPD rates, at 5166 cases. Histoplasmosis was documented in 16 cases mostly with disseminated disease and presumed in 21 with HIV infection. This study constitutes the first attempt to estimate the burden of several types of serious fungal infections in Bangladesh.

Full Text Available The number of fungal infections at any given time in Argentina is not known. Here we estimate the burden of serious fungal infections in Argentina for the first time. Specific population statistics were searched from multiple sources, local literature was identified, and estimates made. Some additional data were sourced from the Ministry of Health, the Global Initiative for Asthma (GINA program, and national haematology and transplant societies. Argentina has a population of 43.8 million, with 25% of this total being children under 15 years. The predicted candidemia annual incidence is 2193 cases, with 50% occurring in the ICU. At a 6% prevalence rate, an estimated 593,695 women suffer from recurrent vulvovaginal candidiasis. Invasive aspergillosis is relatively common because of high smoking and chronic obstructive pulmonary disease (COPD rates, with 268 cases in immunocompromised patients and another 1938 in the 168,000 COPD patients admitted to hospital. Asthma is also common, affecting 14% of adults, and so allergic bronchopulmonary aspergillosis (ABPA and severe asthma with fungal sensitization (SAFS are major problems. An estimated 432 cases of cryptococcal meningitis (CM—90% of them in AIDS patients—and 1177 cases of Pneumocystis pneumonia (PCP occur each year. The estimated annual case number of disseminated histoplasmosis is 404 in AIDS patients, almost as frequent as CM. Paracoccidioidomycosis annual incidence is estimated at 219, and coccidioidomycosis at 16 cases. At least 881,023 people (>2.01% in Argentina are affected by a serious fungal disease annually, with considerable morbidity and mortality.

2012-08-15

We evaluated, by CFD simulation, effects of accessory ostium (AO) on maxillary sinus ventilation. A three-dimensional nasal model was constructed from an adult CT scan with two left maxillary AOs (sinus I) and one right AO (sinus II), then compared to an identical control model with all AOs sealed (sinuses III and IV). Transient simulations of quiet inspiration and expiration at 15 L/min, and nasal blow at 48 L/min, were calculated for both models using low-Reynolds-number turbulent analysis. At low flows, ventilation rates in sinuses with AOs (I ≈ 0.46 L/min, II ≈ 0.54 L/min), were both more than a magnitude higher than sinuses without AOs (II I ≈ 0.019 L/min, IV ≈ 0.020 L/min). Absence of AO almost completely prevented sinus ventilation. Increased ventilation of sinuses with AOs is complex. Under high flow conditions mimicking nose blowing, in sinuses II, III, and IV, the sinus flow rate increased. In contrast, the airflow direction through sinus I reversed between inspiration and expiration, while it remained almost constant throughout the respiration cycle in sinus II. CFD simulation demonstrated that AOs markedly increase maxillary sinus airflow rates and alter sinus air circulation patterns. Whether these airflow changes impact maxillary sinus physiology or pathophysiology is unknown. Copyright © 2012 Elsevier B.V. All rights reserved.

2017-01-01

Full Text Available Background. Thyroidectomy is one of the most frequently performed surgical procedures worldwide. Despite technical advances and high experience of thyroidectomy of specialized centers, it is still burdened by a significant rate of postoperative complications. Among them, the skin sinus formation is an extremely rare postthyroidectomy complication. Here, we first report the incidence of the skin sinus formation after thyroidectomy to identify the causes for skin sinus formation after thyroidectomy and to discuss its prevention and treatment options. Methods. A retrospective analysis was carried out of patients who underwent excision operation of fistula for postthyroidectomy skin sinus formation. Data were retrieved from medical records department of the Affiliated Hospital of Inner Mongolia Medical University. Results. Of the 5,686 patients who underwent thyroid surgery, only 5 patients (0.088% had developed skin sinus formation. All 5 patients successfully underwent complete excision of fistula. Conclusion. Infection, foreign body, thyroid surgery procedure, combined disease, and iatrogenic factors may be related with skin sinus formation after thyroidectomy. To reduce the recurrence of postoperative infections and sinus formation, intra- and postoperative compliance with aseptic processing, intraoperative use absorbable surgical suture/ligature, repeated irrigation and drainage, and postoperative administration of anti-inflammatory treatment are to be followed.

1996-01-01

The purpose of this study was to investigate by CT the origin of radiodense maxillary sinus concretions and whether CT densitometry is effective in the prediction of maxillary sinus aspergillosis and in the differentiation of the origin of these concretions. In a prospective study in 21 patients with radiodense maxillary sinus concretions detected by radiography, a preoperative CT study of the paranasal sinuses and the concretions was undertaken. Additional scans of the upper alveolar ridge were also performed. Radiological findings were compared with clinical symptoms and with CT findings, especially CT densitometry of the sinus concretions and dental root-filling material. All patients underwent a functional Caldwell-Luc operation; histological and microbiological examinations were performed. Fifteen of the 21 patients (71.4%) with radiodense concretions had a histological and microbiological diagnosis of sinus aspergillosis. The sinus concretions had CT densities higher than 2000 HU (Housfield units) in 15 patients and lower than 2000 HU in 6. Fourteen of 15 patients (93.3%) with concretions ahving CT densities higher than 2000 HU had a postoperative diagnosis of maxillary sinus aspergillosis. The mean CT density of the sinus concretions in patients with maxillary sinus aspergillosis was 2868 HU (range 1870-3070 HU), and in patients without aspergiollosis was 778 HU (range 228-2644 HU). The mean CT density of the dental root-filling material was 2866 HU (range 2156-3070 HU). Paranasal sinus CT with CT densitometry of a sinus concretion has a higher accuracy than standard radiogrpahy and clinical findings in the prediction of maxillary sinus aspergillosis (93.3% vs 71.4%). CT densitometry helps to confirm the dental origin of maxillary sinus concretions and to explain a possible dental pathogenesis of maxillary sinus aspergillosis. (orig.)

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.

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

2017-01-01

Full Text Available Background. Using a sinus tarsi rotational flap is an uncommon approach to treating chronic open infective lateral malleolus bursitis. Methods. We treated eight patients, including six males, using this approach. First, we debrided all the infected tissues and used a negative pressure wound closure system where needed. After acute infection had been controlled, the local rotational flap was used for cases where the wound could not be closed by a simple suture or bone exposure. The rotational flap was detached with a curved skin incision at the sinus tarsi next to the open wound and sutured to the defect, paying careful attention to the superficial peroneal nerve. The donor site was managed with a split-thickness skin graft. Results. The patients’ mean age was 74.1 years. Six patients had a wound after suppurative infection, but two patients had ulcer-type bursitis. Six patients demonstrated full flap healing, but two patients had venous congestion necrosis. Conclusion. A sinus tarsi rotational flap is a useful method to ensure healing and coverage of chronic open lateral malleolus bursitis, especially for small to medium wounds with cavity and bone exposure.

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.

Vertical bone loss in edentulous maxillary alveolar processes may necessitate a sinus lift before the placement of dental implants. We have measured and assessed maxillary sinuses meticulously before the operation and evaluated the postoperative results of the operation with magnetic resonance imaging (MRI). Thirteen edentulous maxillary regions in eight patients were included in the study. The patients were examined 1 week before and 3 months after the sinus lift operations using a 1.5 T superconductive MR imager that gave oblique sagittal T2-weighted images with slices 2 mm thick without a gap. The images that were obtained 3 months after the sinus lift operations confirmed that vertical height had increased. We obtained high quality images without any artefacts during a short examination period with a high-resolution scanner. The results showed that it is possible to assess the maxillary sinus before the sinus lift and to evaluate the postoperative results using MRI accurately in three dimensions without the risk of radiation. This makes MRI a suitable alternative to computed tomography (CT).

Introduction: Ectopic sphenoid sinus pituitary adenoma is a rare tumour originating from embryologic remnants of Rathke's pouch. Although it is considered a clinically benign neoplasm, necrosis is encountered in 25% of cases and it can invade adjacent bone structures. Aims: To establish clinical, radiological and histopathological features of ectopic sphenoid sinus pituitary adenoma. Material and methods: Analysis of three cases: two females and one man, aged 61-70. Results: One patient presented with a unilateral hearing loss, the other two with headache and vertigo. They all suffered from type 2 diabetes mellitus. Neurological examination revealed no abnormality. Radiological imaging showed a sphenoid sinus space-occupying soft-tissue lesion with bone erosion in 2 cases and empty sella in 2 patients whereas one had a normal pituitary gland. All were operated on via the transnasal approach. Total resection was achieved in one patient and subtotal in two; in two cases we observed intact sellar dura and in one intact sellar floor. Histopathology showed immunoreactivity for synaptophysin in all cases and cytokeratin in two. The Ki-67 index was less than 2%. Immunohistochemical staining demonstrated growth hormone cells in all cases whereas prolactin and adrenocorticotropin in two. The patients were discharged home in good condition with no neurological deficits. Conclusions: Ectopic sphenoid sinus pituitary adenoma should always be considered in differential diagnosis of sphenoid sinus lesion in the elderly, especially in coexistence with empty sella or type 2 diabetes mellitus. Since ectopic sphenoid sinus pituitary adenoma is a benign lesion, surgical removal is an effective treatment. .

MRV is an important blood vessel imaging and diagnostic tool for the evaluation of stenosis, occlusions, or aneurysms. However, an accurate image-processing tool for vessel comparison is unavailable. The purpose of this study was to develop and test an automated technique for vessel cross-sectional analysis. An algorithm for vessel cross-sectional analysis was developed that included 7 main steps: 1) image registration, 2) masking, 3) segmentation, 4) skeletonization, 5) cross-sectional planes, 6) clustering, and 7) cross-sectional analysis. Phantom models were used to validate the technique. The method was also tested on a control subject and a patient with idiopathic intracranial hypertension (4 large sinuses tested: right and left transverse sinuses, superior sagittal sinus, and straight sinus). The cross-sectional area and shape measurements were evaluated before and after lumbar puncture in patients with idiopathic intracranial hypertension. The vessel-analysis algorithm had a high degree of stability with <3% of cross-sections manually corrected. All investigated principal cranial blood sinuses had a significant cross-sectional area increase after lumbar puncture (P ≤ .05). The average triangularity of the transverse sinuses was increased, and the mean circularity of the sinuses was decreased by 6% ± 12% after lumbar puncture. Comparison of phantom and real data showed that all computed errors were <1 voxel unit, which confirmed that the method provided a very accurate solution. In this article, we present a novel automated imaging method for cross-sectional vessels analysis. The method can provide an efficient quantitative detection of abnormalities in the dural sinuses. © 2016 by American Journal of Neuroradiology.

The purpose of this study was to examine the differences in representation of a globular radiopaque mass on the pantomograms and Waters' views and to compare the efficacy of periapical radiograms, pantomograms and Waters' views in detection of defects on the internal walls of the maxillary sinus. This study was performed with dried human skull. For the study of difference of radiopaque mass shadow in the two views, rubber ball with a diameter of 10mm was used as the experimental lesion. It was placed successively on the internal wall of the anterior, posterior, medial, lateral walls and floor of the maxillary sinus. To examine the detectability of defects for radiographic techniques, defects were formed in the anterior, posterior, medial, lateral walls, and floor of the maxillary sinus. They were formed with 0.5 mm, 0.75 mm, 1.0 mm, 2.0 mm and 3.0 mm sized steel round burs with a slow speed dental handpiece. By subsequently plugging the holes with zinc oxide eugenol paste, radiopaque defects were produced. After that the periapical radiograms, the pantomograms and the Waters' views were taken each and every defect. The obtained results were as follows: 1. Rubber balls placed on each internal wall of maxillary sinus were correctly depicted on the posterior wall and the floor in case of the pantomogram, and on the anterior wall and the medial wall in case of the Waters' view. 2. On the detectability of defects for each radiographic technique, radiolucent defects were detected in different places of each technique. Periapical radiogram could detect 1.0 mm defect on the floor of the maxillary sinus, pantomogram could detect 2.0 mm defect on every internal wall of the maxillary sinus, and Waters' view could detect 3.0 mm defect on the anterior wall of the maxillary sinus. 3. On the detectability of defects for each radiographic technique, radiopaque defects were detected in different places for each technique. Periapical radiogram could clearly detect 0.5 mm defect on

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. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

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

Maxillary sinus agenesis - report of two cases

2000-01-01

Agenesis or aplasia of the maxillary sinuses is an extremely rare condition, and only eight cases have been reported in the world medical literature. These malformations may arise as a result of developmental defects. Two cases of unilateral agenesis of the maxillary sinus are presented and the radiological abnormalities and the embryology are discussed. The literature is also reviewed. (author)

We report a case of a 17-year-old male who had hit the front of his head in a traffic accident. CT scan revealed contusional hemorrhage and pneumocephalus of the left frontal lobe 10 hours after the accident. A month later he complained of rhinorrhea and CT scan revealed intracerebral pneumocephalus. One day he complained of headache and began to vomit after he sneezed. CT scan revealed that the pneumocephalus had become worse and air had spread throughout the subarachnoid space. Bone CT scan revealed the air communicated from the frontal sinus to the intracerebral air cavity. 3D-CT scan revealed bone defect in the roof of the ethmoid sinus. The intraoperative findings revealed that the intracerebral air cavity communicated with the frontal sinus and ethmoid sinus. Though the brain which dropped into the paranasal sinus, adhered to the dura mater around the bone defect, a part of the brain had come off from the dura mater around the frontal sinus. We suspected that the intracerebral air cavity communicated with the frontal sinus initially. When the air cavity communicated with the ethmoid sinus secondarily, intracranial pressure abated and air came into the subarachnoid space from the frontal sinus.

OBJECTIVE There are no guidelines for the management of postoperative lateral sinus thrombosis following posterior fossa surgery. Introducing treatment-dose anticoagulant therapy during the immediate postoperative period increases the risk of intracranial bleeding. This study assessed the incidence of and risk factors associated with postoperative lateral sinus thrombosis and the complications related to thrombosis and/or anticoagulation. METHODS This study was a retrospective monocentric analysis of adult patients who underwent surgical removal of a posterior fossa space-occupying lesion with available postoperative imaging. Postoperative lateral sinus thrombosis was defined as a T2 * hypointensity within the venous sinus and/or a filling defect on postcontrast MRI or CT scan. RESULTS Among 180 patients, 12 (6.7%; 95% CI 3.0-10.4) were found to have lateral sinus thrombosis on postoperative imaging, none of whom were symptomatic. Unadjusted risk factors for postoperative lateral sinus thrombosis were a history of deep venous thrombosis (p = 0.016), oral contraceptive pill (p = 0.004), midline surgical approach (p = 0.035), and surgical exposure of the sinus (p < 0.001). Seven of the patients (58.3%) with a postoperative lateral sinus thrombosis received immediate treatment-dose anticoagulant therapy. Lateral sinus recanalization occurred radiologically at a mean time of 272 ± 23 days in 85.7% of patients (6 of 7) undergoing treatment-dose anticoagulant therapy and in 20% of patients (1 of 5) not receiving treatment-dose anticoagulant therapy. Postoperative complications occurred in 56.2% of patients (9 of 16) who received treatment-dose curative anticoagulant therapy and in 27% of patients (45 of 164) who did not. CONCLUSIONS Incidental radiological lateral sinus thrombosis following posterior fossa surgery has an incidence of 6.7%. To further define the benefit-to-risk ratio of a treatment-dose anticoagulant therapy, a prospective trial should be considered.

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.

Frontal sinuses and head-butting in goats: a finite element analysis.

Science.gov (United States)

Farke, Andrew A

2008-10-01

Frontal sinuses in goats and other mammals have been hypothesized to function as shock absorbers, protecting the brain from blows during intraspecific combat. Furthermore, sinuses are thought to form through removal of ;structurally unnecessary' bone. These hypotheses were tested using finite element modeling. Three-dimensional models of domesticated goat (Capra hircus) skulls were constructed, with variable frontal bone and frontal sinus morphology, and loaded to simulate various head-butting behaviors. In general, models with sinuses experienced higher strain energy values (a proxy for shock absorption) than did models with unvaulted frontal bones, and the latter often had higher magnitudes than models with solid vaulted frontal bones. Furthermore, vaulted frontal bones did not reduce magnitudes of principal strain on the surface of the endocranial cavity relative to models with unvaulted frontal bones under most loading conditions. Thus, these results were only partially consistent with sinuses, or the bone that walls the sinuses, acting as shock absorbers. It is hypothesized that the keratinous horn sheaths and cranial sutures are probably more important for absorbing blows to the head. Models with sinuses did exhibit a more ;efficient' distribution of stresses, as visualized by histograms in which models with solid frontal bones had numerous unloaded elements. This is consistent with the hypothesis that sinuses result at least in part from the removal of mechanically unnecessary bone.

This article presents methods to improve MR imaging approach of disorders of the renal sinus which are relatively uncommon and can be technically challenging. Multi-planar Single-shot T2-weighted (T2W) Fast Spin-Echo sequences are recommended to optimally assess anatomic relations of disease. Multi-planar 3D-T1W Gradient Recalled Echo imaging before and after Gadolinium administration depicts the presence and type of enhancement and relation to arterial, venous, and collecting system structures. To improve urographic phase MRI, concentrated Gadolinium in the collecting systems should be diluted. Diffusion-Weighted Imaging (DWI) should be performed before Gadolinium administration to minimize T2* effects. Renal sinus cysts are common but can occasionally be confused for dilated collecting system or calyceal diverticula, with the latter communicating with the collecting system and filling on urographic phase imaging. Vascular lesions (e.g., aneurysm, fistulas) may mimic cystic (or solid) lesions on non-enhanced MRI but can be suspected by noting similar signal intensity to the blood pool and diagnosis can be confirmed with MR angiogram/venogram. Multilocular cystic nephroma commonly extends to the renal sinus, however, to date are indistinguishable from cystic renal cell carcinoma (RCC). Solid hilar tumors are most commonly RCC and urothelial cell carcinoma (UCC). Hilar RCC are heterogeneous, hypervascular with epicenter in the renal cortex compared to UCC which are centered in the collecting system, homogeneously hypovascular, and show profound restricted diffusion. Diagnosis of renal sinus invasion in RCC is critically important as it is the most common imaging cause of pre-operative under-staging of disease. Fat is a normal component of the renal sinus; however, amount of sinus fat correlates with cardiovascular disease and is also seen in lipomatosis. Fat-containing hilar lesions include lipomas, angiomyolipomas, and less commonly other tumors which engulf sinus

Computer-assisted surgery (CAS) has found widespread use in functional endonasal sinus surgery (FESS) over the past few years. The present study investigates if CAS leads to a better outcome in FESS. All patients who underwent endonasal sphenoethmoidectomy were enrolled in a prospective, non-randomized case-control study. The procedures were done without CAS (group A) in 2003 and with CAS (group B) in 2004, using a Stryker navigation unit. Sixty-two patients (113 sphenoidectomies) were included in group A and 61 patients (109 sphenoidectomies) in group B. The underlying disease was recurrent chronic sinusitis or polyposis nasi in all patients except for inverted papilloma in one patient from group A and in two patients from group B. The follow-up period was 12 months. Symptom scores were assessed preoperatively and at 12 months postoperatively, using a questionnaire. A CT-scan was obtained in all patients preoperatively and at 6 months postoperatively. No significant difference was found between group A and B, neither with respect to symptom scores at 12 months postoperatively, nor in postoperative CT-scans. The operation strategy did not change by the introduction of CAS. The frontal sinuses were entered in group A and B in 59% and 64% of the patients, respectively. All parameters improved significantly postoperatively, compared to the preoperative values. As far as complications are concerned, two anterior orbital injuries and one retrobulbar haematoma occurred in group A and one postoperative lacrimal stenosis in group B. CAS does not lead to a better clinical outcome in FESS. Our data suggest that the rate of complications may be reduced using CAS. However, studies with a much larger number of patients would be necessary in order to definitely answer the question of whether CAS reduce complications in FESS.

We aimed to define the classification of frontal sinus pneumatization patterns according to three-dimensional volume measurements. Datasets of 148 sides of 74 dry skulls were generated by the computerized tomography-based volumetry to measure frontal sinus volumes. The cutoff points for frontal sinus hypoplasia and hyperplasia were tested by ROC curve analysis and the validity of the diagnostic points was measured. The overall frequencies were 4.1, 14.2, 37.2 and 44.5 % for frontal sinus aplasia, hypoplasia, medium size and hyperplasia, respectively. The aplasia was bilateral in all three skulls. Hypoplasia was seen 76 % at the right side and hyperplasia was seen 56 % at the left side. The cutoff points for diagnosing frontal sinus hypoplasia and hyperplasia were '1131.25 mm(3)' (95.2 % sensitivity and 100 % specificity) and '3328.50 mm(3)' (88 % sensitivity and 86 % specificity), respectively. The findings provided in the present study, which define frontal sinus pneumatization patterns by CT-based volumetry, proved that two opposite sides of the frontal sinuses are asymmetric and three-dimensional classification should be developed by CT-based volumetry, because two-dimensional evaluations lack depth measurement.

To evaluate the anatomic variations of the paranasal sinuses on computed tomographs. The author examined the CT images of the paranasal sinuses retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The highest incidence of anatomic variation of the paranasal sinuses in bilateral structures was agger nasi cell (73.2%), followed by concha bullosa (31.1%), Onodi cell (24.0%), Haller cell (19.8%), maxillary sinus septum (13.0%), paradoxical middle turbinate (2.5%), pneumatized uncinate process (2.0%), and bent uncinate process. The highest incidence of anatomic variation in midline structures was nasal septum deviation(53.2%), followed by nasal septumaerated (29.4%), bulla galli (24.7%) asymmetric intersphenoid septum (22.3%), and nasal septum spur (13.8%). The correlation between anatomic variation and paranasal sinusitis was not found. The results of this study will aid in the diagnosis and treatment of paranasal sinus diseases, especially in the treatment planning before functional endoscopic surgery.

Skeletal changes among beta (β) thalassemia children are well documented, but without available data regarding sino-nasal passages alterations. The authors investigated the maxillary sinuses and sino-nasal passages changes in β-thalassemia children and correlated such changes with the amount of transfused red cells and the erythroid marrow activity. Clinical analyses including otorhinolaryngical examination (ORL) were obtained in twenty β-thalassemia children and 20 matched healthy controls. Hemoglobin (Hb), serum ferritin, soluble transferrin receptor (sTfR) levels and bone mineral density of the lumbar spine (BMD ls) were assayed. The two groups were analyzed for the CT image parameters: bone thickness, anterior and posterior choanae diameters, extramedullary hematopoiesis and chronic rhinosinusitis (CRS) RESULTS: Nasal congestion/obstruction was identified in 14 (70%) children. Eight patients (40%) had criteria of chronic rhinosinusitis. In comparison with the normal controls, the increase in the roof, floor, medial, anterior, lateral and posterior maxillary bony walls thickness was significantly higher (1.26, 2.46, 2.6, 2.9, 3.23 and 5.34-folds, respectively). The mean posterior choanae horizontal, vertical diameters and their surface area were significantly reduced in the patients compared to the controls. The mean anterior maxillary wall bone thickness directly correlated with sTfR (P=0.047) while that of the posterior wall correlated inversely with Hb level (P=0.013). The mean vertical posterior choanae diameter had positive correlation with the amount of transfused red cells (P=0.001) and negative correlation with sTfR (P=0.001). The Hounsfield unit of maxillary sinus wall had direct relation with BMDls (P=0.003) CONCLUSIONS: Thalassemia children are at risk of different folds increase of maxillary sinuses walls thicknesses utmost at posterior and lateral walls. Other sino-nasal morbidities include diminished posterior choanal diameter, nasal obstruction

Angiofibromas are histologically benign, but unencapsulated and highly vascular tumors with a potential of local destructive effect. Angiofibromas predominantly originate from the posterolateral wall of the nasopharynx. Extranasopharyngeal angiofibromas are extremely rare and mostly seen in maxillary sinus and ethmoid sinus. In this article, we report a 21-year-old male case who was admitted with headache and diagnosed with an angiofibroma originating from the sphenoid sinus.

Pediatric frontal mucocele secondary to a bifid frontal sinus septum.

Plikaitis, Christina M; Purzycki, Adam R; Couture, Daniel; David, Lisa R

A mucocele is a mucus-containing sac lined with epithelium that arises within a sinus when its drainage is compromised. The frontal sinus is the most common location, with frontal mucocele development occurring when the nasofrontal duct becomes obstructed because of polyps, bone tumors, prior surgery, sinusitis, trauma, or anatomic variation. We report an unusual case of a sterile pediatric frontal mucocele presenting as a slowly enlarging forehead mass due to a bifid frontal sinus septum. A 9-year-old girl presented to the craniofacial clinic for evaluation of a right frontal mass that had been slowly growing over the past year. She was otherwise healthy and had no history of previous trauma or sinus infections. Computed tomography (CT) scan results revealed a localized frontal fluid collection with protrusion and thinning of the anterior frontal bone between 2 midline bony septii. Surgical cranialization of the frontal sinus was performed. The anatomy of her lesion seen both on CT scan and intraoperatively likely explains this unusual case presentation. Instead of the usual inciting event of an intact frontal sinus drainage system becoming blocked, this patient seemed to have a primary developmental lack of any drainage system that led to her mucocele. During formation of her frontal sinus, she developed a bifid septum within the midline that excluded a portion of her frontal sinus from the lateral nasofrontal ducts. With mucus-producing epithelium trapped within these bony confines, pressure began to mount with expansion and thinning of the bone both anteriorly and posteriorly. The lack of any infectious symptoms and sterile culture results may support that this space developed primarily and was never in continuity with the external drainage system. Only 4 other patients have been reported with asymptomatic forehead swelling as the only presenting symptom, with the age ranging from 33 to 79 years. This patient represents the first clinical report of a congenital

Assessment of maxillary sinus volume for the sinus lift operation by three-dimensional magnetic resonance imaging.

To calculate sinus and bone graft volumes and vertical bone heights from sequential magnetic resonance imaging (MRI) examinations in patients undergoing a sinus lift operation. MRI scans were obtained pre-operatively and at 10 days and 10 weeks post-operatively, using a 0.95 tesla MRI scanner and a three-dimensional (3D) magnetisation prepared, rapid acquisition gradient-echo (MP-RAGE) sequence. Estimates of the bone graft volumes required for a desired vertical bone height were made from the pre-operative MRI scan. Measurements of the graft volumes and bone heights actually achieved were made from the post-operative scans. The MRI appearance of the graft changed between the 10 day and 10 week scans. We have proposed a technique which has the potential to give the surgeon an estimate of the optimum volume of graft for the sinus lift operation from the pre-operative MRI scan alone and demonstrated its application in a single patient. Changes in the sequential MRI appearance of the graft are consistent with replacement of fluid by a matrix of trabecular bone.

CT characterization of inflammatory paranasal sinus disease in cystic fibrosis

International Nuclear Information System (INIS)

Eggesboe, H.B.

2002-01-01

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

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

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

The European positional paper on rhinosinusitis and nasal polyps: has the introduction of guidance on the management of sinus disease affected uptake of surgery and acute admissions for sinusitis?

Rhinosinusitis is a common condition with adults experiencing 2-5 episodes per year. The European Positional Paper on Rhinosinusitis and Nasal Polyps (EP3OS) published in 2005 and updated in 2007 provided evidence-based guidelines on the management of sinus disease promoting a conservative approach to treatment. This study examines the effect of EP3OS on sinus surgery uptake and acute admissions for sinusitis in England and Wales. A retrospective study using the national electronic health databases of England (Hospital Episodes Statistics, HES online) and Wales (Patient Episodes Database of Wales, PEDW) was undertaken from 2000 to 2010 using the OPCS-4 codes E12-E17 (sinus surgery) and ICD10 code J01 (acute admission for sinusitis). Data were analysed for effect following the introduction of the EP3OS in 2005 using linear regression and Chi squared analysis. 116,370 sinus procedures and 10,916 acute admissions for sinusitis were made during the study period. No significant decrease in sinus surgery procedures occurred following the introduction of the EP3OS as may have been expected (p > 0.05), although subgroup analysis suggested a significant increase in Wales (p introduction of EP3OS (p 0.05). The EP3OS appears to have had little impact on the rates of sinus surgery but more conservative approaches to managing of sinus disease may have led to an increase in acute admissions. Further research is required to investigate whether changes in practice were adopted.

Management of frontal sinus trauma includes coronal or direct open approaches through skin incisions to either ablate or obliterate the frontal sinus for posterior table fractures and openly reduce/internally fixate fractured anterior tables. The objective of this prospective case-series study was to evaluate outcomes of frontal sinus anterior and posterior table trauma using endoscopic techniques. Prospective evaluation of patients undergoing surgery for frontal sinus fractures was performed. Data were collected regarding demographics, etiology, technique, operative site, length involving the posterior table, size of skull base defects, complications, and clinical follow-up. Forty-six patients (average age, 42 years) with frontal sinus fractures were treated using endoscopic techniques from 2008 to 2016. Mean follow-up was 26 (range, 0.5 to 79) months. Patients were treated primarily with a Draf IIb frontal sinusotomies. Draf III was used in 8 patients. Average fracture defect (length vs width) was 17.1 × 9.1 mm, and the average length involving the posterior table was 13.1 mm. Skull base defects were covered with either nasoseptal flaps or free tissue grafts. One individual required Draf IIb revision, but all sinuses were patent on final examination and all closed reductions of anterior table defects resulted in cosmetically acceptable outcomes. Frontal sinus trauma has traditionally been treated using open approaches. Our findings show that endoscopic management should become part of the management algorithm for frontal sinus trauma, which challenges current surgical dogma regarding mandatory open approaches. © 2017 ARS-AAOA, LLC.

Evaluation study of the sinus lift technique in combination with autologous bone augmentation in dogs' frontal sinus. Limited cone beam CT image and histopathological analyses

International Nuclear Information System (INIS)

Takahashi, Tatsuo

2002-01-01

The posterior area of the maxilla has often been considered inadequate for the insertion of dental implants due to insufficient height of the alveolar bone by atrophic reduction and the maxillary sinus expansion. This anatomic problem may be resolved with augmentation of the floor of the maxillary sinus. The purpose of this study is to evaluate the effectiveness of sinus lift and grafting with the iliac crest bone performed in the dog frontal sinus as a model of the human maxillary sinus. Time course evaluations of bone volume after insertion of implants were performed by the limited cone beam CT (Ortho-CT), histopathological study and NIH-image digital analysis. New bone formation was identified as early as 2 weeks after the implant insertion. The bone volume was increased continuously until 13th week. High-density bone was found in the cervix of the implant after 26 weeks. However, the bone was lost at apex area of the implant and air cavity of the frontal sinus expanded. Ortho-CT findings showed good correlation with histopathological course of the lesion and bone volume identified by the NIH image analysis. The results revealed first time whole course of the bone remodeling after implant insertion into the frontal sinus of a dog. The data also provide an appropriate timing of the implant prosthesis and promise usefulness of the Ortho-CT in planning efficient implant treatment. (author)

Objective: To study a rare CT finding of pulsatile tinnitus (PT) caused by sigmoid sinus abnormalities. Methods: The imaging data of PT caused by sigmoid sinus abnormalities were analyzed retrospectively in 15 patients (15 female). The median age was 45 years (24 to 63 years). The duration of persistence pulsatile tinnitus was from 0.5 year to 36.0 years (median time, 2.0 years). The tinnitus was at left side in 5 patients and right side in 10 patients. Fifteen patients underwent HRCT of the temporal bone. Of them, 12 patients underwent cerebral CT angiography and CT venogram (CTA/CTV), and 9 patients underwent cerebral digital subtraction angiography (DSA). Nine patients underwent transmastoid reconstruction surgery of the sigmoid sinus. Of them, the tinnitus was at left side in 2 patients and right side in 7 patients. Paired rank sum test was used to compare the cross-sectional area of the sigmoid sinus of the tinnitus side and normal side.Results: On HRCT, foca bony coarse defect is shown in the anterior sigmoid wall in 11 patients and anterolateral sigmoid wall in 4 patients. On CTA/CTV, the sigmoid sinus focally protuded into the adjacent mastoid air cells and formed diverticulum in 10 patients. The pulsatile tinnitus disappeared immediately after transmastoid reconstruction surgery of the sigmoid sinus in all 9 patients. The cross-sectional area of the sigmoid sinus of the tinnitus side was 100.6 (41.5-96.2)mm 2 , it was 77.0 (92.1-122.4)mm 2 in the nonmal side (Z=2.158, P=0.031). Conclusion: Focal bony defect of the sigmoid wall with sigmoid sinus diverticula is one of the causes which lead to pulsatile tinnitus, which can be easily identified by imaging examination.

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

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

Full Text Available Introduction: Endoscopic surgery is a new standard method of treatment for chronic sinusitis. During this operation even small amount of bleeding may reduce the visual field of surgeon significantly and make the procedure troublesome. In this study we have compared the operative condition between patients who receive either remifentanil or halothane for general anesthesia. Materials and Methods: Endoscopic sinus surgery was performed in 60 patents. Pre- medication was done by fentanil and midazolam and induction was done by propofol and atracurium. Halothane or remifentanil was used in two groups of patients respectively for anesthesia maintenance. Monitoring was performed during anesthesia. Bleeding volume was measured and operation field condition was assessed by the surgeon. Results: Personal characteristics such as age and sex were the same in both groups. Intra- operative systolic blood pressures was significantly lower in remifentanil group but diastolic and mean blood pressure and heart rate didn’t change after induction and during maintenance in both groups. Recovery time in remifentanil group was also significantly shorter than halothane group. Finally bleeding volume was lower and operation field condition was better significantly in remifentanil group. Conclusion: Remifentanil is a good choice to maintain an ideal anesthesia for endoscopic sinus surgery.

Full Text Available Background: Cerebral venous sinus thrombosis (CVST is a rare form of stroke seen in young and middle aged group, especially in women due to thrombus of dural venous sinuses and can cause acute neurological deterioration with increased morbidity and mortality if not diagnosed in early stage. Neurological deficit occurs due to focal or diffuse cerebral edema and venous non-hemorrhagic or hemorrhagic infarct. Aim and Objectives: To assess/evaluate the role of Magnetic Resonance Imaging (MRI and Magnetic Resonance Venography (MRV as an imaging modality for early diagnosis of CVST and to study patterns of venous thrombosis, in detecting changes in brain parenchyma and residual effects of CVST using MRI. Materials and Methods: Retrospective descriptive analysis of 40 patients of CVST diagnosed on MRI brain and MRV was done. Results: 29/40 (72.5% were males and 11/40 (27.5% were females. Most of the patients were in the age group of 21-40 years (23/40-57.5%. Most of the patients 16/40 (40% presented within 7 days. No definite cause of CVST was found in 24 (60% patients in spite of detailed history. In 36/40 (90% of cases major sinuses were involved, deep venous system were involved in 7/40 (17.5% cases, superficial cortical vein was involved in 1/40 (2.5% cases. Analysis of stage of thrombus (acute, subacute, chronic was done based on its appearance on T1 and T2WI. 31/40 (77.5% patients showed complete absence of flow on MRV, while 9/40 (22.5% cases showed partial flow on MR venogram. Brain parenchyma was normal in 20/40 (50% patients while 6/40 (15% cases had non-hemorrhagic infarct and 14/40 (35% patients presented with hemorrhagic infarct. Conclusion: Our study concluded that MRI brain with MRV is sensitive in diagnosing both direct signs (evidence of thrombus inside the affected veins and indirect signs (parenchymal changes of CVST and their follow up.

Full Text Available OBJECTIVE: Chronic lymphocytic leukemia (CLL is the most common adult leukemia. A few studies have been reported about the relationship between CLL and paranasal sinuses. We aimed to investigate the paranasal manifestations of CLL and to determine the expression of nuclear factor-ĸB (NF-kB and tumor necrosis factor (TNF-α in the nasal mucosa in patients with CLL. MATERIALS AND METHODS: This study was a clinical trial that involved 40 patients. Group CLL (n=20 consisted of patients with early-stage CLL who were followed-up at the hematology clinic and who did not receive any treatment. The control group (n=20 consisted of patients who had undergone concha surgery because of nasal obstruction. Paranasal sinus computer tomography scans of all patients were taken, they were scored on the basis of the Lund–Mackay system, and sinusitis findings were recorded. The biopsy material taken from the inferior concha head of all patients was immunohistochemically stained with primary antibodies against NF-kB and TNF-α. RESULTS: There were no statistically significant differences between the two groups with respect to NF-κB (p=0.716 and TNF-α staining scores (p=1.000. The Lund–Mackay scores were significantly higher in the CLL group than in the control group (p=0.004. Fourteen patients had sinusitis at different locations, while the most common diagnosis was maxillary sinusitis (n=8 in the CLL group. CONCLUSION: This study showed that patients with early-stage CLL tend to have rhinosinusitis. However, NF-kB and TNF-α may not have a role in the inflammatory process involving the paranasal sinuses in patients with CLL.

Full Text Available Background and Aims: There is no study in the literature that investigates an asymmetric morphological feature of the frontal sinus (FS. Materials and Methods: Four hundred and sixty-nine consecutive direct X-rays of FSs were analyzed for the asymmetry between the right and left sides. When an asymmetry in the height and contour of the FS existed, this difference was quantified. Results: Of the 469 patients, X-rays of 402 patients (85.7%, there was an asymmetry between right and left sides of the FS. Of these 235 (50.1% were dominant on the left side, whereas 167 (35.6% were dominant on the right, the sinuses of remaining 67 patients (14.3% was symmetric. Statistical Analysis: The comparisons between parameters were performed using Wilkinson signed rank test. The relationship between handedness and sinus asymmetry was also examined by two proportions test. There is statistically significant difference between the dominance of left and right FS. Conclusions: Hemispheric dominance may have some effect (s of on sinus asymmetry of the human cranium. Surgeons sometimes enter the cranium through the FS and knowledge of asymmetric FS is important to minimize surgical complications.

An occipital sinus draining into the sigmoid sinus has been termed the oblique occipital sinus (OOS). The frequency, anatomical features, patterns, and relationship with the transverse sinus of the oblique occipital sinus were analyzed in this study. The study included 1805 patients who underwent brain CT angiography during a 3-year period from 2013 to 2015. CT examinations were performed using a 64-slice MDCT system. The OOS was identified in 41 patients (2.3%). There were many anatomical variations in the oblique occipital sinuses. A hypoplastic or aplastic TS was seen in 31 (75.6%) of the 41 patients with OOS. Many anatomical variations in the oblique occipital sinus can be seen on CT venography. Some OOSs function as the main drainage route of the intracranial veins instead of the TS. Thus, careful examination is essential for preoperative evaluation in posterior fossa lesions.

Recently, several authors have shown that simultaneous sinus lift and implantation using autologous platelet-rich fibrin as the sole filling material is a reliable procedure promoting bone augmentation in the maxillary sinus. The aim of this study was to examine the effect of simultaneous sinus lift and implantation using platelet-rich fibrin as the sole grafting material on bone formation in a canine sinus model. An implant was placed after sinus membrane elevation in the maxillary sinus of six adult female mongrel dogs. The resulting space between the membrane and sinus floor was filled with autologous platelet-rich fibrin retrieved from each dog. The implants were left in place for six months. Bone tissue was seen at the lower part of the implants introduced into the sinus cavity. The height of the newly formed bone around the implants ranged from 0 mm to 4.9 mm (mean; 2.6 ± 2.0 mm) on the buccal side and from 0 mm to 4.2 mm (mean; 1.3 ± 1.8 mm) on the palatal side. The findings from this study suggest that simultaneous sinus lift and implantation using platelet-rich fibrin as sole grafting material is not a predictable and reproducible procedure, especially with respect to the bone formation around the implants in the sinus cavity.

Manor, Yifat; Garfunkel, Adi A

2018-01-01

To describe a rare case of odontogenic brain abscess. A healthy, 35-year-old male had two dental implants placed in a simultaneously augmented maxillary sinus. One implant failed and the patient developed a maxillary sinusitis that failed to improve following antibiotic treatment at home. The neglected sinus infection led to formation of a brain abscess. The patient was hospitalised only when he had pan sinusitis with neurological signs. Symptoms were headache attacks, a subfebrile fever and a purulent secretion from the left nostril. The osteomeatal complex was blocked, the maxillary sinus was filled with pus and the Schneiderian membrane thickened. The patient was treated with intravenous antibiotic treatment. Computerised tomography (CT) and magnetic resonance imaging (MRI) scans and functional endoscopic sinus surgery (FESS), were implemented. When his conditions worsened, the patient underwent a left frontal mini craniotomy. Following the craniotomy and antibiotic treatment, there was a gradual resolution and the patient was dismissed after 2 months in hospital with no neurological deficit or signs of sinusitis. Maxillary sinusitis following dental implant insertion and concomitant maxillary sinus elevation should be treated immediately and thoroughly since untreated sinusitis may cause life-threatening situations such as a brain abscess. In case of severe infection, clinicians should refer immediately the patient to hospital specialists. Conflict-of-interest statement: The authors have stated explicitly that there are no conflicts of interest. The manuscript was self-funded.

This paper assesses dural sinus patency with two-dimensional inflow MR angiography. Twelve patients with potential dural sinus (superior sagittal and transverse sinus) involvement related to tumors of the falx or the convexity (meningiomas, metastasis) were examined with digital subtraction angiography (DSA), Mr imaging (1.5-T Gyroscan system), including T1-weighted (pre- and post-agadolinium) and T2-weighted spin-echo imaging, and MR angiography. For the MR angiographic study, a gradient-echo fast field echo sequence with flow compensation was used. Thin (2-mm), contiguous coronal or transverse sections were acquired sequentially. Three-dimensional reconstruction with MIP processing was then performed. CT, DSA, and MR imaging were performed for presurgical evaluation. Surgical confirmation of sinus patency was obtained for all patients

Full Text Available Ectopic tooth eruption in a non-dental area is a rare entity, and is most common in oral cavity. There have been a few case reports of teeth erupting in mandibular condyle, chin, palate, coronoid process, and maxillary sinus. Ectopic tooth in the maxillary sinus are found incidentally on routine radiological examination, same time they can be symptomatic and associated with pathologies usually dentigerous cyst or odontogenic keratocyst. Facial pain, purulent rhinorrhoea, epistaxis, headache, swelling, and epiphora-related naso-lacrimal duct obstruction can also be seen. By Caldwell-Luc procedure the ectopic teeth within the maxillary sinus are often removed. In this study, a case of ectopic maxillary third molar tooth on right maxillary sinus is presented.

Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. This study was performed retrospectively on 23 patients who had sinus bone graft. Group 1 was 8 patients (10 sinuses) who had a mucous retention cyst, and group 2 was 15 patients (17 sinuses) who had no pathologic history about the maxillary sinus. For these patients, sinus bone graft was performed using the lateral approach technique. The total 51 implants were placed 6.22 weeks on the average after sinus bone graft. Sinus membrane perforation during operation, postoperative complications, marginal bone loss after restorative function, implant success rate, and survival rate were analyzed. There was no complication in group 1, and there were three complications in group 2. In group 2, two cases of implants failed. The types of postoperative complications consisted of two minor infections and one wound dehiscence. Two implants of total 51 implants were removed, and the survival rate of implants was 96.08 % (group 1 100 %, group 2 93.5 %). The total success rate of implants was 92.2 % (group 1 95 %, group 2 90.3 %). The clinical prognosis was not affected by the presence of mucous retention cyst.

A comparative study between the conventional radiological examination and the computed tomographical examination for the diagnosis of maxillary sinus carcinoma was done. CT scan has been more appreciated to detect the tumor invasion in the pterygopalatine fossa, orbit, posterior ethmoid sinus and skull base than the conventional examination. CT scan was most usefull for the determination of size and location of the tumor. The prognosis by the stage-grouping was significantly separated by the new classification with CT scan. Therefore, new TNM classification of maxillary sinus carcinoma with CT scan should be taken into account. (author)

2017-01-01

Full Text Available Fungal infections as a result of freshwater exposure or trauma are fortunately rare. Etiologic agents are varied, but commonly include filamentous fungi and Candida. This narrative review describes various sources of potential freshwater fungal exposure and the diseases that may result, including fungal keratitis, acute otitis externa and tinea pedis, as well as rare deep soft tissue or bone infections and pulmonary or central nervous system infections following traumatic freshwater exposure during natural disasters or near-drowning episodes. Fungal etiology should be suspected in appropriate scenarios when bacterial cultures or molecular tests are normal or when the infection worsens or fails to resolve with appropriate antibacterial therapy.

A lateral approach for sinus elevation using plasma rich in growth factors (PRGF) technology is described. The long-term survival of dental implants installed following a two-stage procedure after sinus elevation using this procedure is reported, using implant loss as the outcome variable. A retrospective cohort study design was used. Eighteen patients received 43 implants (BTI implants, Biotechnology Institute, Vitoria, Spain) with sinus floor elevation. All patients presented a residual bone height of class D (1-3 mm). Implants were installed using a low-speed drilling procedure (50 rpm) without irrigation. Finally, the histological and histomorphometric evaluation of eight samples from PRGF grafted sinus involved in the study was carried out 5-6 months posttreatment. The overall survival rate of dental implants was 100%. The mean follow-up period for all implants was 33 +/- 7 months ranging from 24 to 44 months. In addition, the histomorphometrical evaluation of the samples evidenced a 25.24 +/- 4.62% of vital newly formed bone, 50.31 +/- 15.56% of soft connective tissue, and the remaining 24.46 +/- 12.79% of bovine anorganic bone. Based on these results, this new approach for sinus elevation and implant installation using PRGF technology can be considered safe, simple, effective, and predictable.

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

patients (62%). Four patients with preoperative P. aeruginosa lung colonization (25%) had no regrowth during follow-up; 2 of these had P. aeruginosa sinusitis. Sinonasal symptoms were improved 12 months after ESS and we observed a trend toward better lung function after ESS. Conclusion We demonstrated...... an improvement in CRS-related symptoms after ESS and adjuvant therapy. In selected PCD patients, the suggested regimen may postpone chronic lung infection with P. aeruginosa and stabilize lung function....

Full Text Available Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry. The displacement of dental implants into the sinus membrane, a complication related to the maxillary sinus, is one of the most common accidents reported in the literature. The treatment for this complication is the surgical removal of the implant. A 60-year-old woman with three dental implants displaced into the maxillary sinus (one implant displaced into the left maxillary sinus and two implants displaced into the right maxillary sinus underwent surgery for removal of the implants. The surgery to remove the implants was performed under local anesthesia through the Caldwell-Luc technique. The patient was subsequently administered antibiotic, anti-inflammatory, and analgesic drugs. The patient returned 7 days after the surgery for suture removal and is being regularly monitored to determine whether future rehabilitation of the edentulous area is necessary. In conclusion, surgical removal of the dental implant displaced into the maxillary sinus is the treatment of choice. This technique is appropriate because it allows the use of local anesthesia and provides direct visualization for the removal of the implants.

The anatomic variations of the paranasal sinuses are common findings. The importance of such variations predisposing disease through the obstruction of the drainage pathway has been discussed by several authors, although it is not yet a matter of agreement. The literature was reviewed and a iconographic assay was prepared aiming the discussion of the importance of the main anatomic variations of the paranasal sinuses. The prevalence of anatomic variations of the paranasal sinuses varies largely amongst studies and its role in sinus disease is controversial. In this article, it is described the different variations associated to paranasal disease and how they relate to pathologic conditions. Most studies confirm the concept that anatomic variations of the paranasal sinuses are related to disease when they obstruct the drainage pathways. The knowledge of such alterations and its relations to pathologic conditions is expected from the general radiologist. (author)
