Endoscopic Sinus Surgery in Patients Infected With HIV

Objectives To be able to plan appropriate surgical treatment for patients with HIV infection who have sinusitis refractory to medical therapy. Design We retrospectively reviewed the charts of 186 patients with HIV who required surgical treatment for sinusitis between 1987 and 1998. One hundred sicharts provided the necessary information and an adequate follow‐up to be included in the study. Collected data included preoperative and postoperative symptoms, radiographic staging, CD4 count at the time of surgery when available, and type and e‐tent of surgery. Results Surgical treatment evolved over the 12 years from limited surgery to standard endoscopic sinus surgery (ESS). Eighteen patients had invasive fungal disease or complications of sinusitis requiring radical surgery. Thirty‐six patients were treated with minimal procedures to address involved sinuses only. These patients were treated between 1987 and 1991. Recurrent disease or further complications occurred in 80.6% of the patients in this group. Since 1992, 52 patients were treated with standard ESS following the same indications for HIV? patients. This group had an improvement of symptoms in 75% of the cases, a rate comparable to the success rate in HIV? patients. Conclusions HIV+ patients undergoing standard ESS enjoy a satisfactory success rate. HIV+ patients with surgical indication for endoscopic sinus surgery should be treated as non‐HIV+ patients. Apparently, low CD4 count (< 100) does not serve as a contraindication for definitive surgery.     

The role of nasal cavity disinfection in the bacteriology of chronic sinusitis

OBJECTIVES: Several factors may influence the results of bacteriological studies in chronic rhinosinusitis. We investigated the potential role of nasal cavity disinfection in the bacteriology of the bulla ethmoidalis in patients suffering from chronic sinusitis. MATERIAL AND METHODS: Bacteriology of the bulla ethmoidalis was studied in 176 consecutive adult patients presenting a chronic sinusitis refractory to standard medical treatment who underwent functional endoscopic sinus surgery. Two different techniques were used: (A) a technique with nasal vestibule and facial disinfection with chlorhexedin (N = 89 patients and 165 samples) vs. (B) a technique with facial, nasal vestibule and nasal cavity disinfection with a povidone-iodine solution followed by a cleansing of the nasal cavity (N = 87 patients and 166 samples). RESULTS: Culture rate was 89.6% (183 bacterial isolates) for technique (A) vs 76.5% (164 bacterial isolates) for technique (B) (p < 0.001). Major bacteria encountered in the (A) group and in the (B) group were respectively: Coagulase Negative Staphylococcus: 77 vs 40 isolates (p < 0.001); Coagulase positive Staphylococcus: 44 vs 30 isolates (p = 0.061); Streptococcus pneumoniae: 4 vs 5 isolates; Others: Streptococcus sp.: 12 vs 16 isolates; Haemophilus influenzae: 8 vs 6 isolates; Enterobacteriacea: 33 vs 53 isolates (p = 0.013) and others Gram Negative Bacilli: 3 vs 7 isolates. CONCLUSIONS: The standard (A) technique to study the bacteriology of the bulla ethmoidalis in patients with chronic sinusitis yielded a higher percentage of positive culture and of bacterial isolates than a more advanced (B) technique. This is mainly due to the higher percentage of contaminant bacteria such as Coagulase Negative Staphylococcus recovered with the standard technique. Enterobacteriacea and others Gram Negative Bacilli were more often encountered into the bulla ethmoidalis with the technique where disinfection of the nasal cavity was performed.     

Bacteriology of chronic sinusitis: the bulla ethmoidalis content

OBJECTIVE: To study the microbiology of the bulla ethmoidalis of patients who suffered from chronic sinusitis. DESIGN: A prospective study performed at the Saint-Luc universitary clinic (University of Louvain) from June 1999 to December 2000. MATERIAL AND METHODS: Seventy seven patients underwent functional endoscopic endonasal surgery during this period for chronic sinusitis refractory to standard medical treatment. All the patients presented symptoms for more than 3 months. After Povidone-Iodine disinfection, samples were taken into the bulla ethmoidalis after its opening with an endoscopic endonasal control. Samples were transferred to the microbiology laboratory using a thioglycolate medium for aerobic and anaerobic cultures. RESULTS: One hundred forty eight samples were studied. Culture rate was 73.6%. Thirty nine samples remained sterile. In the 109 culture positive specimens, 135 bacterial isolates were recovered. The main results are: Staphylococcus coagulase negative: 31, Staphylococcus aureus: 22, Streptococcus sp: 20, other Gram positive Cocci: 5, Haemophilus influenzae: 4, non-fermentative Gram negative bacilli: 6, Enterobacteriaceae: 45, anaerobic bacteria: 2. CONCLUSION: Enterobacteriaceae or enteric gram negative bacilli were frequently encountered in the bulla ethmoidalis of patients suffering from chronic sinusitis. This report suggests that endoscopically guided culture obtained from the ethmoid sinus may accurate our understanding of the microbiology of chronic ethmoidal sinusitis and underline the importance of Enterobacteriaceae in this disease.     

Correlation between microbiology and previous sinus surgery in patients with chronic maxillary sinusitis

Aspirates of 108 chronically inflamed maxillary sinuses were processed for aerobic and anaerobic bacteria. There were 295 bacterial isolates: 109 aerobic and facultative, and 186 anaerobic. The predominant aerobic isolates were Staphylococcus aureus (17 isolates), alpha-hemolytic streptococci (14), Pseudomonas aeruginosa (12), Moraxella catarrhalis (10), and Haemophilus spp (8). The predominant anaerobes were Peptostreptococcus spp (61), Prevotella spp (45), Fusobacterium spp (15), and Propionibacterium acnes (14). Analysis of the medical histories revealed a correlation only between the microbial results and previous sinus surgery. Pseudomonas aeruginosa and gram-negative aerobic bacilli (GNAB) were more often isolated in patients who had surgery (9 of 33 patients had P aeruginosa and 17 had GNAB) than in patients who did not have surgery (3 of 75 had P aeruginosa and 7 had GNAB; p < .001). Anaerobes were isolated more often in patients who did not have surgery (69 of 75 patients) than in those who had previous surgery (21 of 33 patients; p < .001). These findings illustrate the unique microbiological features of chronic maxillary sinusitis that persist after sinus surgery.     

Timing of Endoscopic Sinus Surgery in Children: Is There an Impact on Outcome?

OBJECTIVES/HYPOTHESIS: Endoscopic sinus surgery in children continues to be a controversial issue. Major factors in determining when to operate are the duration of the disease and duration of medical treatment. STUDY DESIGN: Prospective study of children referred to a tertiary center. PATIENTS AND METHODS: Eighty-three patients underwent endoscopic sinus surgery for refractory chronic sinusitis. All patients were followed prospectively to evaluate their response to surgery for a mean follow-up period of at least 1 year. A chi2 analysis and logistic regression analysis were performed to determine statistical difference between duration of symptoms and outcome. RESULTS: The overall success rate of endoscopic sinus surgery was 80%. Children who had surgery between 6 and 12 months of symptoms despite continued medical therapy had an 84% success rate, those who had surgery between 12 and 18 months had a 74% success rate, and those with more than 18 months of treatment for symptoms had an 81% success rate (P > .05). CONCLUSIONS: Duration of the symptoms of chronic sinusitis in children of more than 6 months was not a predictor of success of endoscopic sinus surgery in these children. Although there seemed to be a trend toward having a more successful procedure in children who had surgery between 6 and 12 months of medical treatment versus those who had surgery after more than 12 months of medical treatment, this did not reach statistical significance. A prospective study with more patients may shed more light on this subject.     

Endoscopic sinus surgery in children with chronic sinusitis: a pilot study

This pilot study assessed the safety and preliminary data on the efficacy of endoscopic ethmoidectomy in children with chronic sinusitis. A total of 168 patients were evaluated for chronic sinusitis, and 31 were deemed appropriate candidates for ethmoidectomy. All patients were medical management failures. Twenty-six percent of the patients had asthma, 23% had some immune deficiency, 23% had allergies, and 2 patients (1%) had cystic fibrosis. All patients were followed for at least 1 year postoperatively. The only surgical complication was minor middle meatal scarring that developed in two patients. Overall, 71% of the patients were considered normal by their parents 1 year postoperatively. Of the 24 patients who did not have an underlying systemic disease (immune deficiency or cystic fibrosis) postoperatively, 80% were considered normal by their parents, 12% were improved but continued to have some symptoms, and 8% had unsatisfactory results. Seven children with underlying systemic disease had to undergo revision ethmoidectomy for persistent symptoms.     

Effect of telithromycin and azithromycin on nasopharyngeal bacterial flora in patients with acute maxillary sinusitis

OBJECTIVE: To explore the efficacy of the ketolide telithromycin compared with azithromycin in eradicating S pneumoniae from the nasopharynx of adults with acute maxillary sinusitis. The growing resistance of Streptococcus pneumoniae to penicillin and macrolides brought about the development of a new class of antibiotics-the ketolides-that are effective against resistant pneumococci. SETTING: Otolaryngology clinic. PATIENTS: One-hundred five patients with acute maxillary sinusitis. INTERVENTIONS: Nasopharyngeal cultures were obtained before therapy and 10 to 12 days after initiation of treatment. Fifty-nine patients were treated with 500 mg of azithromycin daily for 3 days and 46 were treated with 800 mg of telithromycin daily for 5 days. RESULTS: Sixty-seven potential pathogens were recovered prior to initiation of therapy in 57 patients, 32 treated with telithromycin and 25 treated with azithromycin: S pneumoniae (31 isolates), Haemophilus influenzae (non-type b) (13), Staphylococcus aureus (8), Streptococcus pyogenes (8), and Moraxella catarrhalis (7). The distribution of the pathogens was similar in both groups. The number of S pneumoniae isolates in the azithromycin group was reduced following treatment from 14 to 8 (43% reduction), and 5 of these 8 isolates were resistant to azithromycin. In contrast, the number of S pneumoniae isolates in the telithromycin group was reduced following treatment from 17 to 1 (94% reduction) (P < .01). This isolate was susceptible to azithromycin and telithromycin. No differences were noted in the eradication rate of all of the other potential pathogens, which were all susceptible to both azithromycin and telithromycin. Development of resistance to the antimicrobial agents used (defined as increase in the minimal inhibitory concentration by at least 2 tubes) was found only in 5 isolates (4 S pneumoniae and 1 H influenzae) recovered only from patients who received azithromycin (P < .05). CONCLUSION: These data illustrate the superiority of telithromycin to azithromycin in the eradication of S pneumoniae from the nasopharynx.     

Maxillary sinus disease of odontogenic origin

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

Sinonasal Disease and Olfactory Impairment in HIV Disease: Endoscopic Sinus Surgery and Outcome Measures

Objectives To investigate the effects of ESS (ESS) on olfactory impairment, disease‐specific symptoms, and general quality of well‐being In HIV+ patients with sinonasal disease. Study Design Study 1: Nasal cytology, rhinomanometry, nasal examination including endoscopy, disease‐specific sinonasal symptoms, olfactory threshold sensitivity, and odor identification testing were performed before and after ESS in HIV+ patients with sinonasal complaints. Study 2: Quality of well‐being was assessed before and after ESS in HIV+ patients with sinonasal complaints and controls. Results Significant olfactory sensitivity loss persisted for patients with chronic sinusitis after ESS, suggesting that the impairment in these patients may be due to viral disease rather than inflammation. Significant improvement in other disease‐specific symptom scores (nasal obstruction, nasal congestion, headache, sinus pain, etc.) and results of the general quality of well‐being assessment showed ESS to be beneficial in the extended health management of HIV illness. Conclusions The current study indicated both olfactory dysfunction and subjective negative symptoms in HIV+ patients with chronic sinusitis. Although olfactory dysfunction remained, ESS was successful in providing marked alleviation of symptomatology in HIV+ patients with chronic sinusitis. The results support ESS as an appropriate treatment option for HIV+ patients with chronic sinusitis.     

Correlation of middle meatus and ethmoid sinus microbiology in patients with chronic sinusitis

Empirical antibiotics constitute the cornerstone of medical therapy for chronic sinusitis due to difficulties of obtaining cultures from the paranasal sinuses. Indirect isolation of the pathogenic microorganisms outside the paranasal sinuses with a non-invasive method may enable administration of specific antibiotics. In this prospective study, we obtained cultures from the middle meatus and ethmoid sinuses of 193 sides from 127 patients who had undergone FESS for chronic sinusitis with a method that minimizes the risk of nasal contamination. The same bacterial species were isolated from both the ethmoid sinus and middle meatus in 59.3% of the cultures. There was no bacterial growth in either site in 32.3% of the cultures. The overall correlation rate of middle meatus and ethmoid sinus cultures was estimated to be 91.6%. In conclusion, middle meatal cultures can be used for the isolation of pathogenic microorganisms indirectly, while administration of specific antibiotics can be possible according to the results of these cultures.     

Presence of fungus in sinus cultures of cystic fibrosis patients

BACKGROUND: Sinonasal pathology is nearly universal in the cystic fibrosis (CF) population. The bacteriology of sinus cultures from CF patients and the implications of sinus bacterial pathogens in this group have been studied; however, sinus fungal isolates from CF patients have not been examined in the literature. METHODS: We reviewed 30 consecutive CF patients undergoing endoscopic sinus surgery at our institution for the presence of fungal isolates obtained from the sinuses at the time of surgery. RESULTS: Thirty-three percent of fungal cultures were positive in this sample; in addition, two patients were newly diagnosed with allergic fungal sinusitis. CONCLUSION: We examine the possible implications of positive fungal sinus cultures in the CF population.     

Sinusitis in patients with the acquired immunodeficiency syndrome

AIDS patients suffer from multiple immunologic deficits involving humoral and cell-mediated immunity. The humoral deficits place the patient at a higher risk for recurrent bacterial infection than the general population. Sinusitis has been recognized to be a more common problem in AIDS patients than was previously appreciated. A high level of clinical suspicion is important, especially in patients with fever, headaches, or symptoms referrable to the upper respiratory tract. Should sinusitis be demonstrated, aggressive medical management is indicated. Surgical drainage is indicated in patients who worsen in spite of appropriate medical therapy, patients who have signs of systemic toxicity from the sinusitis that do not rapidly improve, and patients with recurrent sinusitis. Further studies are indicated to determine the true incidence of sinusitis in the AIDS population and to elucidate further the immunologic defects involved.

Introduction

Isolated acute sphenoid sinusitis is an uncommon sinus infection, frequently misdiagnosed and not usually considered in the differential diagnosis of acute severe headache, with the potential of serious neurologic complications.

Aim

Describe four patients with acute sphenoid sinusitis who presented with acute onset of severe headache and consider the role of medical or surgical management. Two patients do not required surgical intervention and medical treatment was sufficient. One patient had sphenoidotomy due to meningitis. One patient was performed surgical intervention after fail of medical therapy. Acute isolated sphenoid sinusitis appears to be difficult to diagnose. It is important to be aware of acute sphenoid sinusitis in the setting of new onset severe headache, when imaging studies are unrevealing for intracranial pathology. Medical therapy focused on infection, inflammation, and obstruction may be adequate for resolution, but surgical intervention may be required in certain situations.     

Staphylococcus aureus sinus infections in children

Objective

Staphylococcus aureus can cause sinusitis in children. The predominant MRSA clone in the United States, USA300, has been associated with skin and soft tissue as well as invasive diseases. USA300 has increased among CA methicillin-susceptible S. aureus (CA-MSSA) isolates. We describe the clinical characteristics of pediatric patients with S. aureus cultured from sinus specimens, treated at Texas Children's Hospital (TCH), and characterized their isolates by molecular methods.

Methods

This was a retrospective study of children with endoscopic sinus surgery (ESS) cultures positive for S. aureus between 01/2005 and 12/2008 at TCH. Medical records were reviewed and associated S. aureus isolates were characterized by pulsed field gel electrophoresis (PFGE). Data were analyzed by Mann-Whitney U, Chi-square, Fisher's exact test, and Chi-square for trend.

Results

We identified 56 patients with S. aureus sinus infections; 12 (21%) were MRSA. Seven of 12 (58%) MRSA vs. 5/44 (11%) MSSA were USA300 (p < 0.01). All MRSA isolates were non-susceptible to erythromycin compared to 30% of MSSA (p < 0.01); 75% of the USA300 strains were non-susceptible to erythromycin compared to 36% of the non-USA300 strains (p < 0.04). Co-pathogens were isolated from 77% (43/56) of the patient specimens. Both MRSA and USA300 isolates were associated with Haemophilus influenzae co-isolation (p < 0.05). Patients with USA300 strains were significantly younger (p = 0.02) and more likely to experience snoring as a symptom associated with their sinusitis (p = 0.03) than those infected with non-USA300 strains. Children with MRSA (4/12) tended to have a greater recurrence rate than children with MSSA isolates (5/44) (p = 0.09). No significant differences were observed between groups for fever or complications such as neck cellulitis, nasal abscess, meningitis, subdural empyema, and orbital cellulitis.

Conclusion

MSSA was more commonly isolated than MRSA from sinus cultures of children who underwent ESS at TCH. The majority of ESS cultures positive for S. aureus, were mixed with other respiratory pathogens, principally H. influenzae. USA300 was the major clone among the MRSA sinusitis isolates, but was not associated with more complications than other S. aureus isolates.     

‘Eosinophilic Fungal Rhinosinusitis’: A Common Disorder in Europe?

OBJECTIVES/HYPOTHESIS: The traditional criteria for the diagnosis of allergic fungal sinusitis include chronic rhinosinusitis, "allergic mucin" (mucus containing clusters of eosinophils), and detection of fungi by means of histological examination or culture. In 1999, a group of Mayo Clinic researchers, with a novel method of mucus collection and fungal culturing technique, were able to find fungi in 96% of patients with chronic rhinosinusitis. Immunoglobulin E-mediated hypersensitivity to fungal allergens was not evident in the majority of their patients. Because the presence of eosinophils in the allergic mucin, not a type I hypersensitivity, is probably the common denominator in the pathophysiology of allergic fungal sinusitis, the Mayo Clinic group proposed a change in terminology from allergic fungal sinusitis to eosinophilic fungal rhinosinusitis. Using new techniques of culturing fungi from nasal secretion, as well as preservation and histological examination of mucus, we investigated the incidence of "eosinophilic fungal rhinosinusitis" in our patient population. STUDY DESIGN METHODS: In an open prospective study nasal mucus from patients with chronic rhinosinusitis as well as from healthy volunteers was cultured for fungi. In patients, who underwent functional endoscopic sinus surgery, nasal mucus was investigated histologically to detect fungi and eosinophils within the mucus. RESULTS: Fungal cultures were positive in 84 of 92 patients with chronic rhinosinusitis (91.3%). In all, 290 positive cultures grew 33 different genera, with 3.2 species per patient, on average. Fungal cultures from a control group of healthy volunteers yielded positive results in 21 of 23 (91.3%). Histologically, fungal elements were found in 28 of 37 patients (75.5%) and eosinophilic mucin in 35 of 37 patients (94.6%). Neither fungi nor eosinophils were present in 2 of 37 patients (5.4%). CONCLUSIONS: Our data show that the postulated criteria of allergic fungal sinusitis are present in the majority of patients with chronic rhinosinusitis. Either those criteria will be found to be invalid and need to be changed or, indeed, "eosinophilic fungal rhinosinusitis" exists in the majority of patients with chronic rhinosinusitis. Based on our results, fungi and eosinophilic mucin appear to be a standard component of nasal mucus in patients with chronic rhinosinusitis.     

Prevalence of noninvasive fungal sinusitis in South Australia

BACKGROUND: The aim of this study was to document the prevalence of noninvasive fungal sinusitis in patients with chronic sinusitis and thick viscous secretions in South Australia. METHODS: We studied of 349 patients with chronic rhinosinusitis undergoing endoscopic sinus surgery in a specialized rhinology practice. Patients with nasal polyposis and thick fungal-like sinus mucin had operative samples sent for microscopy and fungal culture. Evidence of atopy was taken as positive radioallergosorbent or skin-prick tests to fungi. RESULTS: One hundred and thirty-four (38%) patients were noted to have thick, viscid sinus mucin, raising suspicion of fungal disease. Ninety-three patients had positive fungal cultures or microscopy (26.6%). It was possible to classify 95.5% of the patients into subgroups of noninvasive fungal sinusitis or nonfungal sinusitis: 8.6% of patients with allergic fungal sinusitis, 1.7% of patients with allergic fungal sinusitis-like sinusitis, 15.2% of patients with chronic fungal sinusitis, one patient with a fungal ball, and the remaining 69% of patients with nonfungal chronic sinusitis. CONCLUSION: This is the first prospective study to evaluate the prevalence of these increasingly widely recognized conditions. It highlights the need for otolaryngologists to be alert to these not uncommon diagnoses in order for early, appropriate medical and surgical management to be instituted.     

Complications of frontal and ethmoid sinusitis

A small percentage of patients with acute frontal or ethmoid sinusitis develop orbital, cranial or CNS complications. At selected University of Tennessee affiliated hospitals, from 1974 to 1978, there were 14 such cases which required major surgical intervention in addition to intensive medical therapy. The most common complication in this series was subperiosteal orbital abscess. The most common bacterial isolates were streptococcus and staphylococcus. A discussion of complications associated with frontal and ethmoid sinusitis is included as well as recommendations for medical and surgical management.     

Resultados de cirugía endoscópica nasal en el tratamiento de sinusitis fúngica invasiva en niños con cáncer e inmunosupresión

Background and objectiveto describe the results of the treatment of invasive fungal sinusitis with nasal endoscopic surgery in an immunocompromised paediatric oncological population.Methodsretrospective study of all patients diagnosed with invasive fungal sinusitis operated in the National Paediatric Oncology Unit between 2012 and 2016. Data taken from their medical history included: epidemiological characteristics, oncological diagnosis, haematological data, symptoms, tomographic studies, surgical interventions, results of pathology and cultures, medications received, complications, evolution and survival.Results18 patients were identified, 7 male and 11 female. The average age was 12 years, 13 had a diagnosis of acute lymphocytic leukemia and 5 of acute myeloid leukemia. Seventeen patients presented severe neutropenia at the time of diagnosis. The most frequently identified aetiological agent was Aspergillus in 13 patients. In 16 patients (89%) the disease was controlled with nasal endoscopic surgery. Ten patients died due to unrelated causes throughout the study.Discussion and conclusionsInvasive fungal sinusitis should be considered a medical emergency due to its high mortality. The diagnosis is based on a high index of suspicion in patients with predisposing factors (leukaemia, neutropenia, persistent fever, nasogastric tube) and endoscopic nasal evaluation. Antifungal medical treatment and aggressive nasal endoscopic surgery is indicated regardless of the patient's condition to reduce the fungal burden and associated high mortality. The treatment must be provided by a multidisciplinary team that includes paediatrics, haemato-oncology, infectology and otorhinolaryngology.     

The association between sinusitis and survival among individuals infected with the human immunodeficiency virus.

The purpose of this study was to determine the association between sinusitis and survival among human immunodeficiency virus (HIV)-infected persons. All patients enrolled in the adult spectrum of disease data base from November 1, 1990 to November 1, 1999 were included. Patients were followed until death, loss to follow-up, or the end of the study on January 10, 2000. A Cox proportional hazard regression analysis was conducted to evaluate the association between sinusitis, various other cofactors, and survival. Of the 7513 HIV-infected patients followed, 57% were <35 years old, 59.5% were black, 78.5% were male, and 20.8% had an opportunistic infection (OI) at entry. The incidence of one or more diagnoses of sinusitis in the cohort was 14.5%. The mean entry CD4 count for the entire cohort was 347.8 (SD, 298.9) and the mean follow-up time was 33.2 months (SD, 25.7). The mean CD4 count at the time of sinusitis diagnosis was 391 (SD, 316). In the multivariate analysis, older age and lower CD4 cell count were associated with death. Sinusitis, gender, and race were not associated with survival. Sinusitis is frequent in individuals infected with HIV. After adjusting for level of immunodeficiency, age, gender, and race, sinusitis is not associated with an increased hazard of death. This may have implications for treatment, because a diagnosis of sinusitis does not portend a poor prognosis in individuals infected with HIV.     

The importance of the anaerobic bacteria in paranasal sinusitis.

The anaerobic examination of the material, obtained by 100 antral punctures, in 66 patients with paranasal sinusitis, showed the importance of the anaerobic bacteria. In 33% we found anaerobes: 12% of the cultures were pure anaerobic, 21% were mixed aerobic-anaerobic. The most frequent anaerobe is the Peptostreptococcus. Anaerobic cultures are more frequently found in the unilateral cases of paranasal sinusitis. The presence of anaerobes does not seem to be dependent on the patient's age, the duration of the sinusitis and the previous administration of antibiotics during the last 3 days. In 76% the anaerobes disappeared after the initial antral puncture and washing.
