Post-functional endoscopic sinus surgery methicillin-resistant Staphylococcus aureus sinusitis.

Methicillin-resistant Staphylococcus aureus (MRSA) is a highly virulent bacterium that is difficult to eradicate. It has become a common nosocomial pathogen, but it also causes sporadic infections in some outpatients. Among 358 chronic sinusitis patients who received functional endoscopic sinus surgery (FESS) for treatment between July 1995 and June 1997 in our department, 18 were infected postoperatively by MRSA by the end of August 1997. One patient was excluded because she received another nasal surgery, partial turbinectomy, and submucous resection of the nasal septum, after FESS. Most of 17 MRSA infected patients presented themselves with mucopurulent nasal discharge and/or nasal crust. The treatment was generally difficult because MRSAs were resistant to multiple antibiotics. When quinolone antibiotics were used to treat most patients, the improvement rate was 76.5%. We conclude that MRSA infections in post-FESS patients might affect the outcome of FESS.

Rapid thrombectomy of superior sagittal sinus and transverse sinus thrombosis with a rheolytic catheter device.

Thrombosis of the dural venous sinuses is a potentially lethal condition that remains a diagnostic dilemma. Clinical outcome is typically dependent on the timeliness of diagnosis and definitive treatment. We report a case of successful rapid thrombectomy of extensive thrombus within the superior sagittal and transverse sinuses using a rheolytic catheter device. This appears to be a promising treatment option, particularly in those patients who do not respond to other, more established, forms of therapy.

Carotid Sinus Syndrome: a review of the literature and our experience using carotid sinus denervation.

BACKGROUND: The Carotid Sinus Syndrome (CSS) is a rare condition causing spontaneous syncopal attacks or marked dizziness. METHODS: We studied 28 patients affected by CSS from January 1991 to October 1996. Eleven patients affected by cardioinhibitory type were treated by pace-maker (PM) implant. Seventeen patients had mixed type and all, but one who refused any treatment, entered this study. Carotid Sinus Denervation (CSD) was first performed in 2 of 10 patients who remained symptomatic after PM and in 6 patients as first choice therapy. RESULTS: At a mean follow-up of 30 months no patient submitted to CSD had recurrent syncopal attacks or dizziness. CONCLUSIONS: CSD is a safe and simple technique to abolish either the cardioinhibitory or the vasodepressor response in CSS.

[A comparative observation preoperatively and postoperatively of nasal mucosa in chronic sinusitis treated with endoscopic sinus surgery].

OBJECTIVES: To study morphologic and functional mucosal changes both preoperatively and postoperatively in chronic sinusitis (CS) treated with endoscopic sinus surgery (ESS). METHODS: 1. Saccharin test and light microscopic examination of nasal mucosa were taken preoperatively and postoperatively in 32 cases with CS and in 28 normal subjects as control. 2. Scanning and transmission electron microscopy were performed to exam preoperatively and postoperatively the nasal mucosa in 10 cases with CS and in 2 normal cases as control. RESULTS: 1. The preoperative saccharin test time (STT) in patients with CS was significantly longer than that in the controls (P < 0.001), and the postoperative STT became significantly shorter than that in preoperative one(P < 0.001). 2. The pathological changes of nasal mucosa, such as infiltration in inflammatory cells, edema, polypoid formations and pathologic glands were observed preoperatively. The infiltration in inflammatory cells, edema and polypoid formations were significantly released (P < 0.01) at four months after operation, and there was no significant difference comparing with the controls (P > 0.05). However, the pathologic glands were not reduced even after four months postoperatively. 3. The examination of electron microscopy demonstrated that the ultrastructure of nasal mucosa was impaired preoperatively and almost completely recovered at four months postoperatively. CONCLUSIONS: The normal structure and clearance function of nasal mucosa in patients with CS was impaired preoperatively, and the impaired structure and mucociliary clearing function of nasal mucosa were greatly improved after ESS and almost completely recovered at four months postoperatively. The pathologic glands and secretive function of nasal mucosa may need longer period for recovering.

Treatment for an endosseous implant migrated into the maxillary sinus not causing maxillary sinusitis: case report.

Placement of endosseous implants in the maxilla has been proven to be a reliable treatment modality. If there is lack of supporting bone, the placed implant may not have enough primary stability and may migrate into the maxillary sinus. Displaced implants must be removed. If there are no signs of maxillary sinusitis, augmentation of the resulting alveolar defect can be performed during the same procedure.

[Effect of endoscopic sinus surgery on asthmatic patients with chronic sinusitis and nasal polyps].

OBJECTIVES: To explore the effect of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis and asthma. METHODS: Forty-two patients with asthma who underwent ESS and control group were investigated. Interleukin-4 (IL-4), interferon-gamma (IFN-gamma), soluble interleukin-2 receptor (sIL-2R) and soluble CD23 (sCD23) levels in culture supernatant of peripheral blood mononuclear cell (PBMC) were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: Of these 42 patients 32 (76%), their asthma was relieved greatly after ESS comparing with that before ESS. 14 of 21 patients (67%) taken regular medication for asthma before ESS reported that less medicine was used after operation. CONCLUSION: This study demonstrates that ESS has a favorable effect on asthma in patients with symptomatic chronic sinusitis.

Transitional (cylindric) cell carcinoma with endodermal sinus tumor-like features of the nasopharynx and paranasal sinuses. Clinicopathologic and immunohistochemical study of two cases.

We report two cases of adult patients with primary tumors in the nasopharynx and paranasal sinuses, which were characterized histologically by areas of transitional cell (cylindric or "schneiderian") carcinoma and other foci virtually indistinguishable from endodermal sinus tumor (yolk sac carcinoma). Immunohistochemical studies supported the impression of yolk sac differentiation. Both patients were treated with irradiation and multidrug chemotherapy. One patient died of uncontrollable recurrence of tumor, whereas the other developed locally recurrent, transitional cell carcinoma in the absence of yolk sac tumor. The concurrence of these patterns of carcinoma, which has been undescribed previously to the best of our knowledge, seems to be associated with more aggressive biologic behavior than pure transitional cell carcinomas of this region.

Treatment of sick sinus syndrome with permanent cardiac pacemaker. (Sick sinus syndrome and artificial pacemaker).

Twenty nine patients with sick sinus syndrome were treated from November, 1972 through July, 1976. Six cases had sinus bradycardia, 14 cases had sinoatrial block/sinus arrest and 9 cases had bradycardia-tachycardia syndrome. Twenty five patients received the implantation pacemaker with good result. There was found that an adequate pacing of the heart was effective for the control of the attack of tachyarrhythmia in the case with bradycardia-tachycardia syndrome.

[Sinus node modification by catheter using radiofrequency current in a patient with inappropriate sinus tachycardia. Evaluation of early and late results].

This article reports the early and late results of a patient in whom radiofrequency current was used to ablate an incessant inappropriate sinus tachycardia. During successful radiofrequency application there was a sudden change of rate and subsequent emergence of a stable rhythm with the same sinus node P wave characteristics. During follow-up, normal cardiac cycles were still present after six months of the procedure, although the patient still complained of palpitations, suggesting no correlation with the heart rate.

[Naso-sinusal polyposis in children. Mid-term results of sinusal surgery].

Nasosinusal polyposis in the pediatric population is uncommon and its etiology is unclear. In this eleven-year retrospective study, we describe the etiologic features and evaluate the effectiveness of endoscopic sinus surgery in 49 children. Patients were divided into three groups according to whether nasosinusal polyposis was either isolated (n = 14), or associated with either asthma (n = 5) or cystic fibrosis (n = 30). An allergy was present in 10% of patients with isolated polyposis, 80% of patients with polyposis associated with asthma, and 19% of patients with polyposis associated with cystic fibrosis. The indications for surgery were disabling symptoms, specially chronic nasal obstruction, rhinorrhea and mouth breathing, and failure to respond to medical treatment. No surgical complications were encountered. Most patients reported improvement in quality of life with reduction of nasal obstruction in 83% of cases and rhinorrhea in 61%. Minor asymptomatic recurrence (i.e. a few micropolyp localized on the roof of the ethmoid cavity) was observed in 22.7% of the cases in this series, and major recurrence with the same functional symptoms as before surgery in 13.6%. However, recurrences were higher in patients with cystic fibrosis, since minor recurrence with no clinical manifestation was observed in 28.6% of cases and major recurrence in 17.8%. Endoscopic sinus surgery must be decided in collaboration with the pediatric and pulmonary physicians, and must be performed skillfully. With a mean follow-up of 4 years, results in this series are encouraging.

[Malignant neoplasms of the nasal cavity and paranasal sinuses. Analysis of 216 cases of malignant neoplasms of nasal cavity and paranasal sinuses].

This study is a retrospective analysis of 216 cases of malignant tumours of the nasal cavity and paranasal sinuses, treated from 1965 to 1980. The mean age at diagnosis was 59 years, 70 per cent were men and 30 per cent women. There were 121 (56%) epidermoid carcinomas, and 31 (14%) adenocarcinomas. Three-year and five-year actuarial survival rate was 40 and 33 per cent respectively for epidermoid carcinomas, 72 and 50 per cent respectively for adenocarcinomas. Recurrences occurred in 46 per cent of epidermoid carcinomas and 42 per cent of adenocarcinomas. Early diagnosis is important to improve the survival rate, and radical primary treatment should be carried out to reduce the rate of recurrence.

Chondrosarcoma of the ethmoidal and sphenoidal sinuses. A case of chondrosarcoma arising from postparanasal sinuses.

A case of chondrosarcoma originating within the postethmoidal and sphenoidal sinuses with intracranial invasion will be reported. The patient, a 54-year-old female, presented severe headaches and diminished visual acuity of the right eye. Angiographic findings showed both the left carotid artery to be completely occluded and the right inner carotid artery to be narrowed at the site of the carotid bifurcation. Computerized tomography scan findings showed a tumor, located mainly in the frontal base and temporal fossa, that had invaded the cranium through the skull base. Several tumor excisions were performed using a combined extranasal and transmaxillary approach. The diagnosis 'chondroma' was changed to 'chondrosarcoma' during autopsy.

The effect of endoscopic sinus surgery on mucociliary activity and healing of maxillary sinus mucosa.

The aim of this study was to determine histologic findings in the maxilaarysinus mucosa by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and ciliary activity within the nasal cavity by measuring the speed of mucociliary transport and after endoscopic sinus surgery (ESS). Thirty patients were enrolled. Thirty-eight antral mucosae of 24 24 patients were investigated according to ultrastructural changes and 6 patients were accepted as controls. At the 12th week, 12 antral nasal mucosae specimens of 8 patients were evaluated. All the specimens were taken from the medial rear wall of the antrum. The specimens were observed under a SEM and TEM. The mucociliary activity was measured within the nasal cavity by a saccharin test in all patients before the operation and after 12 weeks. Twenty people served as controls. In the specimens of the preoperative mucosa, the ciliated epithelium was heavily deciliated, interdigitation of the cell was loosened. In the samples taken 12 weeks after the operation, the ciliated cells were irregularly seen, the number of goblet cells was about the same as in the preoperative group and in the control, the number of the gland openings was higher than in the preoperative group and in the control. Also the interdigitation of the cells was enhanced. The histological and morphological features of the mucosa had improved. The period of the preoperative saccharin test was 12.15 minutes, whereas the period of the postoperative test was 9.08 minutes. The improvement was significant but both results were also significantly longer compared to the controls. These observations suggest that the histological, morphological and mucocilliary activity of the mucosa have not yet improved completely, it takes more than 12 weeks to recover, and the patients should be closely monitored in the postoperative months.
