RESUMO

Woakes' syndrome (WS) is a rare entity, defined as severe recalcitrant nasal polyposis with consecutive deformity of the nasal pyramid. WS occurs mainly in childhood and its aetiology remains unclear. We report a case of a 68-year old woman, with aspirin-exacerbated respiratory disease, who presented with recurrent nasal polyposis and progressive broadening of the nasal dorsum. CT scan revealed extensive bilateral nasal polyposis and diffuse osteitis, with anterior ethmoidal calcified lesions. The patient underwent revision endoscopic sinus surgery and nasal pyramid deformity was successfully managed without osteotomies.

RESUMO

Woakes' syndrome is a rare entity defined as recurrent sinonasal polyposis with a consequent nasal pyramid deformity. Only a few cases are reported in the literature. The goal of this study is to present the features of Woakes' syndrome through a clinical case. A 42-year-old man presented with a history of ASA triad. He started self-medication for 5 years. He returned to the otorhinolaryngology department for the aggravation and persistence of symptoms. CT scans showed the deformity and thinning of the nasal bones. A functional endoscopic sinus surgery and correction of nasal pyramid deformity were performed. At 6 months' follow-up, good functional and aesthetic outcomes were observed. Woakes' syndrome was described more than 130 years ago. Treatment includes endoscopic sinonasal surgery and local treatment. Adequate management and good adherence to the therapeutic protocol could be factors to prevent this syndrome.

RESUMO

OBJECTIVES: The aim of the present prospective, randomized, double-blind, and placebo-controlled investigation (approved by the Ethical Committee of Padova University Hospital [Italy]) was to assess the effect of a nasal gel containing a combination of silver sucrose octasulfate and potassium sucrose octasulfate (Silsos gel® [SG]) in wound healing after endoscopic sinus surgery (ESS) for chronic rhinosinusitis in terms of: nasal symptoms (SNOT22), endoscopic appearance of the sinonasal mucosa (Lund-Kennedy score), nasal air flow (anterior active rhinomanometry), evidence of mucosal inflammatory processes (nasal cytology and histology), and microbiological growth. METHODS: Thirty-four patients with chronic rhinosinusitis were randomized on a 1:1 ratio to receive after ESS either SG or placebo (contained only the excipients [carbopol and propylene glycol] in the same concentrations as in SG). RESULTS/CONCLUSIONS: Judging from the present prospective investigation on patients who underwent ESS for chronic rhinosinusitis, treatment with SG seems to enable a significantly faster improvement in specific symptoms (assessed on the validated SNOT22 scale) than placebo. Patients treated with SG also had a quicker improvement in the endoscopic appearance of their nasal mucosa after ESS than patients treated with placebo. These endoscopic improvements in the SG group were also confirmed at the long-term follow-up, while the same did not apply to the placebo-treated group.

RESUMO

The facial region is infrequently affected by necrotizing infections. Orbital necrotizing infections are even rarer, seen following trauma, local skin infection, and sinusitis. The authors report a unique case of orbital necrotizing fasciitis and osteomyelitis resulting from Arcanobacterium Haemolyticum ethmoid sinusitis. No prior occurrences of Arcanobacterial species orbital necrotizing fasciitis/osteomyelitis have been reported.A 16-year-old boy presented to the ER with a 3-day history of fever, chills, headache, and sinus pressure. CT scan revealed soft tissue swelling of the right orbit, forehead, and ethmoid sinusitis. Within 24 hours of admission, he suffered rapidly progressive swelling and erythema of the right orbit and forehead with diminished visual acuity, despite broad-spectrum antibiotics. Orbital exploration revealed frankly necrotic fascia and periosteum along the superior aspect. Lateral canthotomy, cantholysis, decompression of the optic nerve, and soft tissue debridement with bone biopsy was performed. Operative specimens isolated Arcanobacterium Haemolyticum. Pathologic examination revealed right orbital osteomyelitis.

RESUMO

BACKGROUND: Chronic rhinosinusitis (CRS) may occur through heterogeneous disease processes. It is possible that more than 1 inflammatory process underlies CRS in any given patient. If so, heterogeneity in processes may be a function of the spatial organization of the paranasal sinuses. Density characteristics of sinus opacities on computed tomography (CT) scans offer insight into the nature of sinus opacities and disease, in general, and may thus be used to detect spatial heterogeneity of sinus disease within a given patient. METHODS: The study was a retrospective chart review of CRS patients with available sinus CT scans. Radiographic density profiles of sinus opacities were assessed by raw measures of densities (in Hounsfield units [HU]). Radiographic density profiles of the different affected sinuses were compared to each other, checked for correlation, and finally, checked for evidence of clustering using a principal component analysis. RESULTS: Frontal sinus opacities appear to be more heterogeneous, with both higher and lower density components than other sinuses. There was strong correlation between the radiographic density profiles of opacities in the frontal, anterior ethmoid, and sphenoid sinuses (p < 0.001). However, on principal component analysis the radiographic density characteristics of the opacities of the frontal and anterior ethmoid sinuses appeared to cluster together more than the other sinuses. CONCLUSION: Radiographic properties of sinus opacities suggest the nature of sinus opacities are related not only to some common underlying pathology but also to factors related to the specific sinus as well as other spatially close affected sinuses. This suggests an anatomic orientation for sinus pathophysiology in CRS.

RESUMO

BACKGROUND: Initial attention on the pathophysiology of chronic rhinosinusitis (CRS) has focused on eosinophils. Other immune cells such as mast cells (MCs) have been identified and appear to be elevated in CRS with nasal polyp (NP) patients. MCs are commonly linked to immunoglobulin E (IgE)-mediated inflammatory changes characterized by elevated T helper 2 cytokines. Although atopy is a common comorbid condition with CRS, the objective of this study was to determine if elevated MCs are linked primarily to atopic status in CRS patients and to understand the significance of MCs in the pathophysiology of CRS. METHODS: Ethmoid sinonasal mucosa from patients undergoing endoscopic sinus surgery was harvested from 3 groups: healthy control (HC), CRS without NP (CRSsNP), and CRS with NP (CRSwNP) and analyzed by flow cytometry to quantify CD117(+) /CD203c(+) MCs and CRTH2(+) CD4(+) T cells. Relative expression of prostaglandin D(2) synthase in ethmoid mucosa was determined by quantitative real-time polymerase chain reaction (PCR). RESULTS: MCs were significantly elevated in CRSwNP patients as compared to CRSsNP patients and HCs. This elevation was not solely dependent on the presence of IgE-mediated hypersensitivity. Relative expression of prostaglandin D(2) synthase was also increased in CRSwNP patients along with an associated presence of a CRTH2(+) memory CD4(+) T cell population. CONCLUSION: Elevated percentages of MCs are found in the sinonasal mucosa of CRSwNP patients, regardless of atopic status. Secreted by MCs, elevated prostaglandin D(2) may play a role in the recruitment of CRTH2(+) cells to the inflamed mucosa of CRSwNP patients.

RESUMO

OBJECTIVE: Endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) may be compromised by postoperative inflammation, polyposis, and adhesions, often requiring subsequent intervention. To address this issue, the authors investigated the safety and effectiveness of controlled delivery of mometasone furoate to the sinus mucosa via bioabsorbable implants deployed at the time of ESS. STUDY DESIGN: Prospective, multicenter, randomized, controlled, double-blind trial using an intrapatient control design. SETTING: Otolaryngology-head and neck surgery centers; both academic and private practices. SUBJECTS AND METHODS: The study enrolled 105 patients with CRS undergoing bilateral ethmoidectomy to compare the effect of drug-releasing to non-drug-releasing implants using an intrapatient control design. Postoperative interventions, polyposis, and adhesions were assessed postoperatively. Efficacy was determined through independent analysis of randomized video-endoscopies by 3 blinded sinus surgeons. Safety assessments included ocular examinations. RESULTS: Implants were successfully deployed in all 210 ethmoid sinuses. Compared with control sinuses with non-drug-releasing implants, the drug-releasing implant provided a 29.0% relative reduction in postoperative interventions (P = .028) and a 52% (P = .005) decrease in lysis of adhesions. The relative reduction in frank polyposis was 44.9% (P = .002). Similar reductions were observed in real-time grading performed by the clinical investigators. No clinically significant changes from baseline in intraocular pressure or cataracts were observed. CONCLUSION: This study provides a high level of evidence that use of steroid-releasing implants that apply a sustained release of corticosteroid improves surgical outcomes by reducing synechiae formation, polyposis, and the need for postoperative interventions, with no observable ocular safety risk.

RESUMO

OBJECTIVE: To determine whether variations in gene expression exist at multiple subsites along the sinonasal tract in patients with chronic sinusitis with polyps and in healthy controls. STUDY DESIGN: Prospective, controlled study. SETTING: Academic medical center. SUBJECTS AND METHODS: Tissue expression levels of 5 genes, previously found to be characteristic of ethmoid polyps, were measured using real-time quantitative polymerase chain reaction in 100 sinonasal tissue samples. Specimens harvested from 5 regions--the ethmoid sinus, septum, inferior turbinate, middle turbinate, and lateral nasal wall--in 10 patients with chronic sinusitis and ethmoid polyps were compared to tissue from similar regions in 10 control patients without sinusitis. Western blot analysis was performed to validate differential gene expression at the protein level. RESULTS: Gene expression levels of ethmoid polyps differed significantly from those of healthy ethmoid mucosa, as well as tissue from 4 surrounding anatomical sites in both patients with chronic sinusitis and controls. Alterations specific to the polyp tissue included downregulated genes, prolactin-induced protein (fold change 377.2 ± 169.0, P < .0001), and zinc α2-glycoprotein (fold change 72.1 ± 26.5, P < .0001), as well as upregulated genes, met proto-oncogene (fold change 2.5 ± 0.7, P = .029), and periostin (fold change 7.5 ± 3.4, P = .003). No significant differences in gene expression was found for neurabin 2 (fold change 1.0, P = .99). CONCLUSION: The transcriptional pattern of ethmoid polyps appears to be unique compared with other subsites in the sinonasal cavity of patients with chronic sinusitis. Care must be taken when collecting specimens for molecular studies of the sinonasal tract to differentiate polyp from nonpolyp tissue in chronic sinusitis.

RESUMO

It seems apparently that the 2 separate anatomical areas (nasal cavity and paranasal sinus mucosa) are indeed one single unit with an identical behavior during inflammatory process. Similar histopathologic evidence in long-term condition could emphasize on the concept of rhinosinusitis in patients with inflammatory paranasal sinus disease. Prospective study was performed on 50 consecutive patients with polyposis in 2 different groups, one with and the other without asthma. Inferior turbine and polyp with ethmoid sinus origin were selected to compare the histopathologic findings of the surgical specimens from the 2 sites (affected sinus vs apparently unaffected nose). The general degree of inflammation, epithelial thickening, and inflammatory cell count were measured. The degree of inferior turbinate inflammation correlated with that of the ipsilateral polyp of ethmoid sinus in both groups. In addition, the total inflammatory cell count was comparable. There was no statistically significant difference in total polymorphonuclear, lymphocyte, and eosinophil count between the 2 sites in each group (P > .05). The ethmoid sinus inflammation in polypoid chronic sinusitis is accompanied by a proportionate inferior turbinate inflammation, not only in the patients with asthma but also in those with isolated sinonasal polyposis.

RESUMO

BACKGROUND: Collecting mucosal biopsies is invasive and creates additional inflammation, hampering a better understanding of nasal and sinus disease evolution and response to treatment. We examine whether sinus secretion collection can replace tissue biopsy for protein determination. METHODS: Prior to surgical intervention for chronic rhinosinusitis (CRS), a piece of gelatin foam was used to collect secretions from the ethmoid mucosa. A tissue biopsy was then taken from the same location. Matrix metalloproteinase-9 (MMP-9) protein levels were measured in each sample. RESULTS: MMP-9 protein levels in secretions and tissues were significantly correlated (p = 0.0033, r = 0.52, by Pearson correlation). CONCLUSION: Secretion collection can replace tissue biopsy for MMP-9 determinations, reducing morbidity. Furthermore, secretion collection allows sequential sampling from the same location.

RESUMO

Multiple theories were described concerning the pathogenesis of orbital infection in rhinosinusitis, but no theory was proved. Understanding the cause of complication can allow its proper management. We speculate that subperiosteal orbital abscess (SPOA) secondary to rhinosinusitis is similar to subperiosteal abscess associated with osteomyelitis of bone all over the body. The objective was to evaluate bony changes of the ethmoidal sinuses in complicated rhinosinusitis patients with SPOA. This prospective controlled study was performed on eight patients undergoing endoscopic sinus surgery drainage for rhinosinusitis complicated with SPOA. Age, radiographic bony characteristics, and histopathological findings were all documented. Ethmoidal bone specimens were examined and assessed histopathologically. Purulence of SPOA was collected and sent for cultures. The authors evaluated normal ethmoidal bone specimens taken endoscopically from the medial wall of obstructing concha bullosa in ten control patients. The analysis revealed CT and histopathologic changes consistent with high grades of ethmoidal bone pyogenic osteitic changes. Coagulase-positive staphylococci were the predominant cultured bacteria (62.5%) in SPOA. These findings suggest that orbital subperiosteal abscess in rhinosinusitis patients is attributed to diffuse higher grades of ethmoidal sinus bony pyogenic osteitis. Staphylococcus aureus is the most commonly involved cultured bacteria. Bony osteitis in rhinosinusitis patients with SPOA is similar clinically and histopathologically in its character and behavior to osteomyelitis of bone all over the body with associated subperiosteal abscess.
