Sinonasal and Laryngeal Sarcoidosis-An Uncommon Presentation and Management Challenge

Sarcoidosis is a chronic inflammatory disease of uncertain etiology characterized by the formation of noncaseating granulomas. The thorax is involved in 95% of cases, but any organ can be involved. Sinonasal or laryngeal involvement is uncommon and can be difficult to diagnose. The reported incidence of sarcoidosis in the upper airway clearly depends on study characteristics, and this creates uncertainty about the actual incidence. In a large prospective study in the United States, upper respiratory tract involvement occurred in 3% of the patients. Some patients have upper airway involvement without thoracic disease, and this presentation may cause delays in diagnosis. These patients have nonspecific symptoms which range from minimal nasal stuffiness to life-threatening upper airway obstruction. Currently, there is no established standard therapy for the management of upper airway sarcoidosis. These patients often respond poorly to nasal and/or inhaled corticosteroids and require long courses of oral corticosteroids. Patients with poor responses to oral corticosteroids or severe side effects may respond to tumor necrosis factor alpha inhibitors. In this review, we will discuss the clinical presentation, pathogenesis, diagnostic tests, drug treatment, surgical management options and the challenges clinicians have managing these patients.

Cholesteatoma and coexisting findings diagnosed incidentally on MRI

The explosive growth in the use of diffusion-weighted magnetic resonance imaging (MRI) in the pre- and postoperative evaluations of patients with cholesteatoma has led to a concomitant increase in the number of incidental findings in this population. We describe our retrospective examination of MRI studies in cholesteatoma patients to look for the presence of other coexisting abnormalities. We examined the brain MRIs of 103 patients-45 males and 58 females, aged 3 to 81 years (mean: 31.9 ± 21.3)-who had undergone pre- or postoperative imaging during the management of a cholesteatoma. The MRIs revealed the presence of at least one other anomaly in 79 of these patients (76.7%)-36 males and 43 females, aged 3 to 81 years (mean: 43.5 ± 18.2). These 79 MRIs detected a total of 124 lesions that had been coexisting with cholesteatomas; some of these lesions had overlapped with the cholesteatoma. The two most common findings were sinonasal mucoperiosteal thickening and polyposis (n = 66) and white-matter changes (n = 29). Our results establish the need for routine skilled interpretation of brain MRIs by expert neuroradiologists to ensure that findings coexisting with cholesteatoma are detected so that appropriate management can be provided.

Underestimation of Rhinogenic Causes in Patients Presenting to the Emergency Department with Acute Headache

OBJECTIVES

Differential diagnosis is essential, since secondary headache due to paranasal sinus lesions are similar in headache characteristics to primary headache. However, since patients visiting the emergency department due to acute severe headache are primarily treated by neurologists, paranasal sinuses lesions and anatomical variations of the nasal cavity causing the headache are commonly overlooked because of the clinician's lack of knowledge about rhinosinugenic headache. This study investigated the prevalence of paranasal sinus lesions and anatomical variations that may cause secondary headaches in patients who were diagnosed as primary headache and treated by neurologists in the emergency room.

METHODS

A retrospective study was done involving 1235 patients who visited the emergency department from January 2008 to December 2012 and who were diagnosed with primary headache. From the axial view of brain computed tomography, examination of sinusitis, mucosal contact points, concha bullosa, isolated sphenoid lesion, and osteoma were done, and location and morphology was analyzed.

METHODS

Three hundred fifty-five of 1235 (28.7%) patients had sinusitis, mucosal contact points, concha bullosa, isolated sphenoid lesion, and osteoma as possible causes for secondary headaches.

CONCLUSION

Differential diagnosis of primary headaches requires knowledge of paranasal sinus lesions including rhinosinusitis or anatomical variations. Also, interdisciplinary evaluation of acute headache presenting to the emergency room is necessary for accurate diagnosis and proper management.

[The clinical research of aviatic nasal diseases with medical evaluation prevention and control intervention]

OBJECTIVE

Exploring the clinical features of aviatic nasal diseases to provide references for medical evaluation, prevention and control measures in aircrew.

METHOD

To analysis and summary 605 cases with 503 pilots of nasal diseases in aircrew during 1966 to 2013.

RESULT

(1) There were 605 cases of aviatic nasal diseases, including 550 cases of general diseases and 55 cases of specific diseases. The general nasal diseases included 140 cases of anatomical abnormalities in nasal cavity type, 290 cases of inflammation in nasal cavity, 73 cases of allergy type, 47 cases of cyst and tumor type, and the specific nasal diseases were 55 cases of sinus barotrauma (SB). (2) The, constituent ratio of SB, which was happened in frontal sinus and /or maxillary sinus, was 95.55%. (3) The constituent ratio of cyst and tumor type in nasal cavity was easier causing to SB than anatomical abnormalities, inflammation, allergy disease in nasal cavity (P < 0.05). (4) The grounded constituent ratio of secondary SB was higher than anatomical abnormalities, inflammation, allergy, cyst and tumor disease in nasal cavity (P < 0.05). (5) The ways of hypobaric chamber tests were different for the kinds of aircrew. The qualified adjustment function of sinuses for barometric pressure was an essential condition for aircrew to continue flying. (6) The key point for the treatment of aviatic nasal diseases was to remove pathological change in nasal cavity and sinus and restore sinus ostium patency. The key point for the medical evaluation was to restore normal sinus pressure balance function.

CONCLUSION

The key point of medical evaluation about aviatic nasal diseases is to assess the sinus pressure balance function in hypobaric chamber tests. Normative treatment and medical evaluation can effectively avoid flight accidents and improve the attendance rate for aircrew.

Low prevalence of oral and nasal human papillomavirus in employees performing CO2-laser evaporation of genital warts or loop electrode excision procedure of cervical dysplasia

Risk of human papillomavirus (HPV) transmission during laser vaporisation of genital warts or loop electrode excision procedure is controversial. An oral rinse, a nasal swabs, history of HPV related diseases and data on HPV exposure were collected from 287 employees at departments of dermato-venerology and gynaecology in Denmark. A mucosal HPV type was found among 5.8% of employees with experience of laser treatment of genital warts as compared to 1.7% of those with no experience (p = 0.12). HPV prevalence was not higher in employees participating in electrosurgical treatment or cryotherapy of genital warts, or loop electrode excision procedure compared with those who did not. HPV 6 or 11 were not detected in any samples. Hand warts after the age of 24 years was more common among dermatology than among non-dermatology personnel (18% vs. 8.0%, p = 0.03). Mucosal HPV types are infrequent in the oral and nasal cavity of health care personnel, however, employees at departments of dermato-venereology are at risk of acquiring hand warts.

[Relationship between children's obstructive sleep apnea hypopnea syndrome and nasal diseases]

OBJECTIVE

To explore the relationship between children obstructive sleep apnea hypopnea syndrome (OSAHS) and nasal diseases.

METHODS

Three hundred and thirty-eight cases of pediatric OSAHS confirmed by polysomnography (PSG) had been enrolled as the treatment group, and divided into mild subgroup, moderate subgroup and severe subgroup according to the obstructive apnea index (OAI) and apnea hypoventilation index (AHI). The other two hundred and seven pediatric vocal cord nodule cases without OSAHS had been randomly selected as the control group. The retrospective analysis of upper respiratory tract infection frequency per year, expression levels of total IgE (tIgE) and allergen-specific IgE (sIgE), results of electronic nasopharyngoscope test and nasal sinus CT scans had been performed in all the pediatric cases. The data were analyzed by SPSS 17.0.

RESULTS

The upper respiratory tract infection frequency per year, ratio of cases with positive results of tIgE, ratio of cases with nasosinusitis, ratio of cases with narrow nasal cavity in the experiment group were respectively 8.7 ± 5.7, 60.9%, 79.9% and 50.0%, while those in the control group were respectively 4.4 ± 2.6, 32.8%, 12.1% and 6.3%, with significant difference between groups (t = 7.578,χ(2) value was 41.943, 237.704, 110.322, all P < 0.01). The multiple regression analysis indicated that, nasosinusitis and narrow nasal cavity were the two major risk factors of pediatric OSAHS (OR1 = 16.008, OR2 = 4.671, all P < 0.01), with combined effects (OR = 113.430, P < 0.01) . The rank test analysis in term of risk factors of severity of OSAHS had indicated that, prevalence of nasosinusitis and narrow nasal cavity were increased as rising severity of OSAHS (χ1(2) = 21.571, χ2(2) = 17.304, all P < 0.01).

CONCLUSIONS

Infection and allergy are risk factors of pediatric OSAHS. Nasosinusitis and narrow nasal cavity are two major risk factors of pediatric OSAHS, which have positive relationship with the severity of OSAHS.

Risk factors associated with asthma phenotypes in dental healthcare workers

BACKGROUND

Exposure in the dental environment can increase the risk of respiratory disease in dental healthcare workers (HCWs). This study investigated the prevalence of asthma phenotypes in dental HCWs and associated risk factors.

METHODS

A cross-sectional study of 454 dental HCWs in five dental institutions in South Africa was conducted. A self-administered questionnaire elicited the health and employment history of subjects. Sera was analyzed for atopic status and latex sensitization. Pre- and post-bronchodilator spirometry was performed.

RESULTS

The prevalence of atopic asthma was 6.9%, non-atopic asthma 5.9% and work-exacerbated asthma (WEA) 4.0%. Atopy and work-related ocular-nasal symptoms were strong predictors of WEA (OR: 3.4; 95% CI: 1.07-10.8; OR: 6.7, 95% CI: 2.4-19.1), respectively. Regular use of personal protective equipment (PPE) was associated with a protective affect (OR: 0.23, 95% CI: 0.1-0.7) among non-atopic asthmatics, while glove use and respiratory protection was protective among atopic asthmatics (OR: 0.39, 95% CI: 0.17-0.89).

CONCLUSION

Identification of risk factors associated with specific asthma phenotypes in dental HCWs can be used to focus preventive strategies for asthmatics.

Three years audit of the emergency patients in the department of ENT of a rural medical college

Surgical audit is a systematic, critical analysis of the quality of surgical care provided, with the aims of improving quality of care, continuing education for surgeons, and guiding appropriate use of health resources. Emergency service is an integral part of any discipline of clinical medicine and it is considered as an indicator of quality of healthcare system. A three years record based, retrospective, cross-sectional study was carried out in the department of ear, nose and throat (ENT) of Midnapore Medical College, Paschim Medinipur,West Bengal to identify the total attendance of various emergency patients, diagnosis made thereafter, the mode of interference and outcome and the potential problems in the quality of care provided to the community. A total of 9051 patients had been admitted/attended in the ENT emergency from January 2008 to December 2010 who were included in this audit. Detailed statistical analysis of the data showed male: female (2.38:1) with the peak in the first decade of life. Majority of the patients were from Medinipur sadar (58.43%). The total otological cases were maximum (42.41%) in comparison to nose (28.98%) and throat (28.60%). The most common ear emergencies were earache due to impacted wax, acute suppurative otitis media, foreign body ear and the trauma/injury. Chronic suppurative otitis media with complications were the least. Amongst the sinonasal emergency, the most common aetiology was the epistaxis and foreign body nose in children. The different types of foreign body impaction in the throat and the inflammatory condition of throat or the inspiratory stridor due to upper airway obstruction were the main emergency situation recorded. Some cases were fatal. The overall mortality was 0.44%.

Classification and prevalence of nasal septal deformity in Koreans according to two classification systems

CONCLUSION

Guyuron type 2 and Mladina type 1 were the most common types of nasal septal deformity (NSD) in Koreans. The Guyuron classification showed a higher concordance rate with computed tomography (CT) findings than the Mladina classification.

OBJECTIVES

The purpose of this study was to classify the NSD according to the Guyuron and Mladina classifications, and to evaluate the correlation between anterior rhinoscopy and CT findings.

METHODS

Each septum of the patients who visited Seoul National University Hospital Health Care Center was classified according to the Guyuron and Mladina classifications. For the patients who underwent septoplasty, the correlation of NSD between anterior rhinoscopy and CT findings was evaluated.

RESULTS

Of 970 patients, 50.3% had NSD. According to the Guyuron and Mladina classifications, type 2 (41.4%) and type 1 (35.4%) were most common, respectively. Among 64 patients who underwent septoplasty, the concordance rates with CT findings were 71.9% for the Guyuron classification and 50% for the Mladina classification. This difference was statistically significant (chi-squared test, p = 0.026).

Methicillin-resistant Staphylococcus aureus (MRSA) on the skin of long-term hospitalised horses

Given the significance of methicillin-resistant Staphylococcus aureus (MRSA) infections for both horses and staff in equine veterinary hospitals, protocols are required to minimise the risk of nosocomial transmission, including the screening of the skin and nasal chambers of equine patients for evidence of infection. The objective of this study was to clarify the potential existence and extent of MRSA on the skin of horses requiring long-term hospitalisation (≥ 6 months). Thirty such horses were sampled at eight different locations on their skin and from their nasal chambers. MRSA was isolated from 12 animals (40%), with all sample sites testing positive on at least one occasion. Organisms were most frequently detected in the nasal chambers (relative sensitivity, 83.3%; 34.5% positive horses; isolation rate 33.3%). Skin presence was found in 30% of animals with the highest isolation rates found at the carpus (16.7%), neck, withers and croup (13.3% each). To achieve a relative screening sensitivity of >90%, at least one skin site was required in addition to nasal sampling. This evidence of skin as well as nasal reservoirs of MRSA in long-term hospitalised horses should facilitate the design of effective screening and containment protocols.

[Mucormycosis. An emergent mycosis]

Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales. It is characterized by rapid progression and high morbidity and mortality in the absence of early diagnosis and prompt treatment. It was an infrequent disease, but in recent years, its incidence appears to have increased. The aim of this paper is to report the cases of mucormycosis diagnosed from 1982 to 2010 at the Hospital de Clinicas José de San Martín, University of Buenos Aires. We diagnosed 10 cases of mucormycosis; the first three between 1982 and 2004 and the last 7 between 2005 and 2010. The incidence from 1980 to 2004 was 0.13 patient-years and the frequency 0.1/10 000 discharges (95% CI 0.00- 0.3). In the period 2005 to 2010, the incidence was 0.86 patients per year with 1.1/10 000 discharges (95% CI 0.5-2.4). There was a pulmonary mucormycosis case (in a patient treated with corticosteroids) and nine rhinocerebral cases, two in neutropenic and seven in diabetic patients. The diagnosis was made by observation of cenocytic hyphae in 10/10 patients. Mucorales were recovered in 8/9 cultures (5 Rhizopus spp and 3 Mucor spp.). In one case diagnosis of pulmonary mucormycosis was made post-mortem. Nine patients were treated with amphotericin B deoxycholate (in 3 patients supplemented with liposomal amphotericin B) and surgery. Three patients underwent hyperbaric chamber. Seven patients had favorable outcome. In conclusion, mucormycosis is a rare disease, but its incidence has increased over the past five years. A good evolution of the patients is linked to early diagnosis and treatment.

Clinico-pathological profile of sinonasal masses: a study from a tertiary care hospital of India

The present study examined the clinico-pathological profile of sinonasal masses in patients attending an Ear Nose Throat clinic of a rural tertiary care hospital of western Maharashtra in India, between May 2007 to June 2009. During the study period, 112 patients presented with sinonasal masses (male 68, female 44; age group 8-70 years). Nasal polyploid masses were non-neoplastic in 80 (71.4%) subjects, and neoplastic in 32 (28.6%) cases. Nasal obstruction was the most common (97.3%) presenting complaint, followed by rhinorrhoea (49.1%), hyposmia (31.25%), intermittent epistaxis (17.9%), headache (16.9%), facial swelling (11.6%) and eye-related symptoms (10.7%). The most common site of origin of polyploid masses was the middle meatus (54.4%) followed by the lateral wall of the nasal cavity (16.1%) and superior meatus (10.7%). Unilateral nasal masses was present in 47.7% patients, while the remaining patients had bilateral nasal masses. Allergic (62.5%) and inflammatory (25%) polyps were the most common non-neoplastic mass. Haemangioma (47.3%) and inverted papilloma (36.8%) were most common benign neoplastic mass; 92.3% of all malignant masses were squamous cell carcinoma. Surgery was the major mode of treatment. It included Caldwell-Luc operation (7.1%), polypectomy (17.8%), excision of mass (25.0%) and functional endoscopic sinus surgery (44.6%). Malignancies were treated with radiotherapy.

Nose and throat complications associated with passive smoking among Congolese school children

OBJECTIVE

To assess associations between nose-throat (NT) diseases and passive smoking prevalence among school children.

METHODS

A cross-sectional survey was carried out on a randomized multistage sample of 381 school children (50.9% males, aged 9.8 ± 3.5 years) from Kinshasa town. Parents and children were asked to fill in a questionnaire detailing their smoking habits. The NT symptoms and diseases were assessed by the survey NT specialist.

RESULTS

The prevalence of passive smoking was 38.6% (n = 147). Residence in peripheral areas, catholic school system, elementary level, exposure of family to passive smoking, history of NT surgery, medicines and menthol inhaling, headache, nasal pain, dysphagia, odynophagia, dysosmia, dysphonia, pharyngeal irritation, dry throat, snooze, and chronic pharyngitis were more reported by passive smokers. After adjusting for confounding factors, passive smoking (OR = 16.7 95%CI 3.3-83.3), catholic system(OR = 2 95%CI 1.2-3.2), and elementary degree(OR = 1.4 95%, CI 1.1-2.1) were identified as independent determinants of chronic pharyngitis.

CONCLUSION

Parents should not smoke in the same room used by their children.

[Mucormycosis: retrospective evaluation of 12 cases]

Mucormycosis is a rare and often fatal invasive fungal infection. Disseminated or pulmonary forms are common in patients with immune deficiency while rhinocerebral form is common in diabetes mellitus. The aim of this study was to evaluate retrospectively the adult mucormycosis cases which were followed up in our hospital between 2007-2010. The cases were evaluated in terms of demographic characteristics, underlying diseases, laboratory, clinical and treatment results. A total of 12 mucormycosis cases (6 were male; age range: 18-74 years; mean age: 50.83 ± 18.27 years) were evaluated. Ten of the 12 cases had definitive diagnosis of invasive fungal infection according to EORTC/MSG (European Organization for Research and Treatment of Cancer/Mycoses Study Group) criteria whereas two had possible mucormycosis. Six cases had rhinoorbital, four had rhinocerabral, one had pulmonary and one had rhinocerebral and pulmonary mucormycosis. Fever (n= 10; 83%), edema in face (n= 8; 67%) and eyes (n= 6; 50%) were the most common symptoms and findings. Mycologic culture was performed in ten cases and was found positive in five cases (four cases had Rhizopus spp. one case had Mucor). In two cases direct microscopy revealed mycelium but culture did not yield any pathogen. Two cases had concomitant Aspergillus spp. growth. Overall mortality rate was determined as 50% (6/12). All of the cases received antifungal therapy (liposomal amphotericin B and posaconazole or itraconazole), however, surgical intervention was applied to five cases. Mean duration of antifungal treatment was 60.8 ± 47.4 days. Mortality rate was lower in cases who received concomitant surgical therapy, but the difference was not found statistically significant (2/5 vs. 4/7, p> 0.05). Hematologic diseases (n= 6) and diabetes mellitus (n= 3) were the most common underlying diseases in mucormycosis cases. Voriconazole prophylaxis applied to three cases with hematologic diseases was detected as a risk factor. Development of mucormycosis in those cases who were under voriconazole prophylaxis, deserves attention. Since this is the largest 3-years series of adult mucormycosis cases reported from a single center and includes the first cases treated with posaconazole, the results of this evaluation may aid to the management of patients with mucormycosis.

Prevalence of Staphylococcus aureus and lack of its lytic bacteriophages in the anterior nares of patients and healthcare workers at a rural clinic

BACKGROUND

Nearly 30% of people in the United States are colonized with Staphylococcus aureus and 1% to 2% with methicillin-resistant Staphylococcus aureus (MRSA) in the anterior nares. However, it is not known if lytic bacteriophages against S. aureus are present in the anterior nares, and if they are, what the prevalence rate is, or if they interfere with S. aureus colonization. The aim of this study was to determine the prevalence of nasal carriage of S. aureus and MRSA and to screen for S. aureus lytic bacteriophages in healthcare environment workers and ambulatory patients.

METHODS

We enrolled 202 individuals into this study. The anterior nares were swabbed to isolate S. aureus, MRSA, and any lytic S. aureus bacteriophages that may be present. Putative S. aureus colonies on blood agar plates were identified using gram stain, catalase and coagulase tests, and confirmed by S. aureus-specific PCR. Presence of staphylococcal lytic bacteriophages were screened by a plaque assay technique using a methicillin-sensitive reference S. aureus strain ATCC 29213.

RESULTS

Of the 49 (24%) individuals who screened positive for S. aureus, two (1%) were positive for MRSA. None of the samples were positive for lytic bacteriophages against S. aureus. Subgroup analysis found no significant difference in the prevalence of S. aureus in the house staff compared to other healthcare environment workers or ambulatory patients of the clinic. Similarly, no significant difference in colonization was noted across the population with respect to age, sex, body mass index, or presence of diabetes mellitus.

CONCLUSION

The prevalence of nasal carriage of S. aureus and MRSA in the studied population was 24% and 1%, respectively, similar to the rate of prevalence in the United States. The study also showed that the anterior nares do not seem to harbor lytic bacteriophages against S. aureus.

Rhinocerebral zygomycosis in Pakistan: clinical spectrum, management, and outcome

OBJECTIVE

To study the disease spectrum and salient management features of 36 patients with histopathologically-confirmed rhinocerebral zygomycosis seen at our academic center over a 16-year period.

METHODS

Retrospective review of patients admitted to the Aga Khan University Hospital in Karachi, Pakistan from January 1991 to December 2006 with histopathologically-confirmed zygomycosis of the head and neck.

RESULTS

Mean patient age was 40 +/- 5.0 years (range, 34-63 years), and 23 (64%) patients were male. Thirty-two (89%) patients were referred from clinical services other than otolaryngology. Underlying predisposing conditions included diabetes mellitus (21 patients), haematologic diseases (9), and renal failure (6). Twenty (55%) patients had limited sinonasal disease, ten (28%) had orbital involvement, and six (17%) had intracranial extension. All patients underwent rigid nasal endoscopy and biopsy, and black necrotic tissue was seen in 22 (61%) instances warranting endoscopic or open surgical debridement. Four of 6 patients undergoing open surgery required orbital exenteration. Overall patient survival was 56% (20/36 patients). Diabetic patients had improved survival (17/21, or 81%) compared to patients with haematologic disorders (3/9, or 33%) (p = 0.001). All six patients with intracerebral disease died. Eighteen of the 22 (82%) patients treated with surgery plus amphotericin B survived vs. two of 14 (14%) receiving amphotericin B alone (p < 0.001).

CONCLUSIONS

In rhinocerebral zygomycosis, an aggressive, multidisciplinary, diagnostic and therapeutic approach that utilizes CT or MRI staging, and combines endoscopic or open surgical debridement with amphotericin B-based antifungal therapy offers the best chance of recovery.

Environmental safety risk research

Pilot epidemiology survey has been conducted with the aim to study the effect of occupational factors on workers in the Zestafoni Manganese Processing Plant. Overall 102 workers have been surveyed. They were selected from the list circulating in the plant ambulance. Selected workers have been surveyed through a standard questionnaire. The survey revealed that prevalence of such diseases as Radiculitis, hypertension, bronchitis, gastritis, and ulcer, ocular and nasal-pharyngeal diseases are high among the workers of the Zestafoni Processing Plant. Study results have shown direct correlation between development of diseases and distance residence from the plant. Prevalence of hypertension, ocular and nasal-pharyngeal diseases, bronchitis was higher among workers lived within distance of 2-5 kilometers from the plant. Positive correlation revealed between length of job and prevalence of bronchitis, ocular diseases, Radiculitis, hypertension, cardiac diseases and gastritis. Among plant workers revealed high prevalence of symptoms characterized the central nervous system disorders such as sleep disorder, insomnia, backache, walking disorders. The results proven correlation between occupational factors and diseases and different symptoms.

[The influence of application of the assisted reproductive technologies on the state of ENT organs in children]

The objective of the present study was to estimate the state of ENT organs in the children born after assisted reproductive technologies (ART). A group of 208 children at the age from 1 to 3 years enrolled in the study included 97 ones born following application of the assisted reproductive technologies. It is concluded that the use of the assisted reproductive technologies has no appreciable effect on the extent and the structure of ENT organ morbidity in the children.

[Quality of life before and after surgery in patients with nasal polyposis]

OBJECTIVES

The postoperative symptoms, paranasal computed tomography (CT) findings and quality of life of the patients who had undergone surgical treatment for nasal polyposis were evaluated.

PATIENTS AND METHODS

This study included 32 patients (18 females, 14 males; mean age 43 years; range 14 to 64 years) who applied to our clinic between January 2008 and January 2009 and were operated on with diagnosis of pure nasal polyps. In addition, 36 healthy volunteers were randomized to the control group. The patients were evaluated before and after surgery, on the 3rd week and 3rd month with routine ear nose and throat physical examination and through the Short Form-36 (SF-36) questionnaire as the nasal symptom scores and quality of life. The SF-36 questionnaire was used in the control group as well. In this SF-36 questionnaire the patients were evaluated for eight domains. Control paranasal CT findings at 6th months after surgery were compared with the CT findings before surgery.

RESULTS

We determined improvement of nasal symptoms in patients (nasal obstruction, headache, loss of sense of smell, rhinorrhea and posterior rhinorrhea) at the 3rd week and 3rd month after surgery compared to before surgery (p<0.05). We also determined improvement in the domains of SF-36 questionnaire (general healthy, physical functioning, problems of emotional role, social functioning, pain, vitality and mental health) at the 3rd week and 3rd month after surgery compared to before surgery (p<0.05). Control paranasal CT findings of patients at 6th months after surgery was also improved significantly compared to before (p<0.001).

CONCLUSION

We determined improvement in all symptoms and quality of life for a short period of time after the surgical treatment performed on patients with nasal polyposis. The paranasal CT has an important place for diagnosis and treatment.

Respiratory and nasal symptoms, immunological changes and lung function among petroleum refinery workers

OBJECTIVE

To assess adverse respiratory effects and immunological changes among petroleum refinery workers.

METHODS

We performed a cross-sectional study including 80 subjects employed in the coking unit of a petroleum refinery (54 males and 26 females, aged 28-56 years, duration of exposure 7-28 years) and an equal number of office workers, matched by sex, age and smoking habits. Asthma and allergic rhinitis diagnosed by a physician, as well as respiratory and nasal symptoms in the last 12 months, were recorded by questionnaire. Evaluation of the subjects under study also included skin prick tests for common inhalable allergens and lung function tests.

RESULTS

We found a similar prevalence of asthma and allergic rhinitis in both examined groups. Prevalence of overall respiratory symptoms was higher among petroleum refinery workers (33.7% vs. 22.5%) with a statistically significant difference for cough (30.0% vs. 13. 7%, p = 0.018) and wheezing (21.1% vs. 8.6%, p = 0.029). Prevalence of overall nasal symptoms was higher among petrol refinery workers (36.2% vs. 23.7%) with a statistically significant difference for runny nose (28.7% vs. 12.5%, p = 0.014). We found a similar prevalence of allergic sensitization to common inhalable allergens in both examined groups. The results of lung function tests showed significantly lower value of MEF50 (61.9% vs. 67.4%, p = 0.019) and MEF75 (56.1% vs. 62.9%, p = 0.000) among petroleum refinery workers. Respiratory impairment was observed in both smoking and non-smoking petroleum refinery workers.

CONCLUSION

Our data suggest that workplace exposure among petroleum refinery workers may lead to respiratory and nasal symptoms and lung function impairment.

[Impact of ambient air pollution by a pulp-and-paper mill on the cytological status of the nasal and oral mucosa in children]

The cytological state of nasal and oral mucosae in the children and adolescents living in the town of Koryazhma was evaluated at the schools located differently from the Kotlas pulp-and-paper mill (PPM). All the Kozyazhma children under examination were found to have an increased epithelocytic alteration index, which is likely to suggest cytotoxic exposure, which was shown to a greater extent with the duration of residence at the school more adjacent to the PPM. The first-form pupils from the school locates more closely to the PPM were found to showed a higher index of natural microflora colonization with buccal epitheliocytes and a trend for an increase in the epitheliocytic differentiation coefficient characterizing the high incidence of diseases.

Dopplerographic correlates of headaches accompanying the chronic nasal and nasopharyngeal pathology

The present study aimed at research of cerebral blood flow in patients with chronic nasal and nasopharyngeal pathology with accompanying headaches before and after appropriate treatment. One hundred and six patients with chronic nasal and nasopharyngeal pathology, aged from 6 to 75 years, 57 male and 49 female have been investigated. According to the type of nasal and nasopharyngeal pathology patients were classified in 5 groups, and were divided in three age categories: 6 -18 years (39 patients), 19- 65 years (38 patients), 66-75 years (29 patients). Headaches were estimated by neurologist before appropriate surgical and conservative treatment, after treatment and 6 months later. Cerebral blood flow was studied before treatment, after treatment and 6 months later by means of Transcranial Dopplerography. Control consisted of 30 age-matched healthy persons. Chronic headaches were established in 63 patients (59%). In all age categories the mean blood velocity in middle cerebral artery, anterior cerebral artery, basilar artery was significantly increased against control (p<0.05), and pulsation index (PI) found to be decreased compared to control. After treatment blood flow velocity in the middle cerebral artery, anterior cerebral artery and in basilar artery in all age groups did not differ significantly from control (p<0.5), and PI was significantly elevated against previous data (p<0.05). Cephalic pains disappeared in 75% of treated patients and 25% noted the significant decrease in pain intensity and frequency. Treatment of chronic nasal and nasopharyngeal pathology can prevent the certain kind of cephalic pains, and improve the clinical course of accompanying headaches.

The effects of silica exposure on upper airways and eyes in denim sandblasters

OBJECTIVE

Silicosis due to denim (or jean) sandblasters is newly described cause of silicosis. In such cases lungs are severely affected due to heavy exposure to silica without serious protection. We aimed to investigate whether silica had an effect on the upper airways and eyes.

METHODS

The study included the patients recently diagnosed with silicosis. For comparisons, a control group was constituted. Firstly, a questionnaire was performed to obtain demographic and exposure characteristics of the cases. Later, routine nasal examination by endoscope and routine eye examination by slit-lamp microscope were performed to investigate presence of rhinitis and/or adenoid vegetation and eye findings associated with dust exposure, respectively, in both patient and control groups. Punch biopsies of the adenoid tissue were obtained using an endoscopic telescope with the patient under local anesthesia and sent for histopathologic examination. In addition, nasal pH and mucociliary clearance were investigated. Both pH and saccharin nasal transport time (SNTT) measurements were performed by two physicians, who reached a final consensus.

RESULTS

The study group consisted of 83 male silicotics with an average age of 23 +/- 6 years, and the control group consisted of 84 age and gender matched healthy individuals. Their mean exposure time was 40 +/- 26 months. On routine nasal examination, silicotics had higher rates of rhinitis (28.9% versus 16.7%) mostly ipsilaterally (p = 0.01), adenoid vegetation (32.5% versus 13.3%/, p < 0.05), conjunctival hyperaemia (70% versus 45%, p < 0.001), pingueculae (68% versus 23%, p < 0.01), papillar formation (40% versus 28%), and higher nasal pH values (7.9 +/- 0.7 versus 6.9 +/- 0.6, p < 0.001), higher SNTT values (19.9 +/- 2.9 versus 10.9 +/- 1.9, p < 0.001) compared with the controls.

CONCLUSION

The results of our study suggest that upper airways and eyes are considerably affected in the patients with silicosis. Thus, appropriate protection is required to prevent the development of such problems in denim sandblasters.

Sublabial transseptal approach to pituitary adenomas with special emphasis on rhinological complications

OBJECTIVE

The aim of this presentation is to show that the sublabial transseptal transsphenoidal approach to pituitary adenomas is the least invasive anatomic route with the lowest postoperative complication rates.

PATIENTS AND METHOD

This study was based on a retrospective analysis of 276 patients with a diagnosis of pituitary adenoma who were surgically treated via the sublabial transsphenoidal route.

RESULTS

The overall complication rate of the presented series was 14.8%. The recurrence rate was 14.1%; there were no deaths or intranasal complications in this series. Postoperative rhinological complications, such as septal perforation, synechiae, and mucosal tear which impaired nasal function, occur rarely with this approach compared to other approaches.

CONCLUSION

Besides the technical advantages of this approach, performance of the initial phase of the operation by an otorhinolaryngologic surgeon is the basis of the low intranasal complication rate in our series.

Acute rise in methicillin-resistant Staphylococcus aureus infections in a coastal community

OBJECTIVE

Describe the incidence of head and neck community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections over a 5-year period at a coastal tertiary medical center.

STUDY DESIGN

Retrospective chart review.

SUBJECTS AND METHODS

All patients presenting to the otolaryngology service with cultures taken from head and neck infections between 1999 and 2004 were eligible for inclusion. Statistical analysis was used to determine significance of the changing incidence of isolated organisms over the study period.

RESULTS

CA-MRSA infections rose from 21% to 64% over the 5-year period. The increasing trend in CA-MRSA infections reached statistical significance from 2003 to 2004. All CA-MRSA isolates were resistant to cefazolin and penicillin, but most were sensitive to clindamycin.

CONCLUSIONS

Our data demonstrates a striking increase in the incidence of CA-MRSA. We have tailored our treatment of cutaneous head and neck infections to include empiric treatment for CA-MRSA using clindamycin. Awareness and monitoring of this trend will be important for all practitioners involved in the care of these patients.

Complications in primary and secondary acquired cholesteatoma: a prospective comparative study of 62 ears

OBJECTIVES

This study aimed to compare the clinicopathologic behavior of complications in primary and secondary acquired cholesteatoma and figure out the differences between them.

DESIGN

This was a prospective cross-sectional study.

METHODS

This was a study conducted in a tertiary referral medical college hospital comprising of 62 ears, of which 32 were in the primary acquired cholesteatoma group (PACG) and 30 were in the secondary acquired cholesteatoma group (SACG). We compared the 2 groups with respect to 7 prognostic variables, as follows: age distribution, sex, duration of ear discharge, pathology in the ear, predisposing disease focus in nose and throat, pattern of complications, and microbiology of ear.

OBSERVATION AND RESULTS

The presence of cholesteatoma increased the risk for complications by more than 2 times in PACG, but the presence of granulation tissue did not show the same risk. More than half of the ears with complication contained some or the other predisposing disease focus in the nose or throat. The PACG was 3 times more prone to complications than the SACG in the presence of these foci. They showed a similar pattern of complications. Brain abscess and mastoid infections were the commonest complications.

CONCLUSIONS

The PACG was more prone to complications than the SACG in the presence of cholesteatoma and focus in the nose and throat. Irrespective of the different pathologic origin of the 2 types, the patterns of complications remained the same with no major differences, indicating a common final pathway in the natural course of the disease.

Trigeminal trophic syndrome

Trigeminal trophic syndrome (TTS) is a rare cause of facial ulceration, which is believed to develop after insult to the trigeminal ganglia or other parts of the peripheral/central nervous system in the trigeminal pathway. The pathogenesis of TTS is poorly understood. Developing a better understanding of TTS will allow early recognition and improved treatment. Although the ulcers develop predominantly on the ala nasi, the literature on ulcer locations is limited. In this article, we review the epidemiologic aspects of TTS, expand on our knowledge of the anatomic location of the ulcers, and discuss current theories for its aetiology and briefly review the approaches to its management.

Head and neck manifestations and quality of life of patients with ectodermal dysplasia

OBJECTIVES

Ectodermal dysplasias (EDs) are a group of genetic disorders characterized by deficient ectodermal and mesodermal development. Studies examining resultant otolaryngologic issues are few. The objectives of this study were to delineate the head and neck manifestations and quality of life in EDs.

STUDY DESIGN AND SETTING

For 75 individuals, comprehensive histories were taken and otolaryngologic examinations were performed, and subjects rated their otolaryngologic symptom severity. A validated quality of life instrument (SF-8) was administered.

RESULTS

The majority of subjects had a diagnosis of hypohidrotic ED (72%). Otolaryngologic conditions included otitis media (28%), cerumen impaction (48%), nasal obstruction/crusting (51%), heat intolerance (76%), and eczema (39%). Physical findings included peg teeth/hypodontia (76%), alopecia (41%), nasal crusting (41%), and saddle nose deformity (44%). Quality of life scores were generally high. Overall, health was rated "good to excellent" by 87 percent.

CONCLUSION

Patients with ED frequently experience significant otolaryngologic symptoms, although most patients report a good quality of life.

SIGNIFICANCE

A greater understanding of the otolaryngologic issues in ED should help facilitate diagnosis and improve management.

Nasal symptoms and signs in children suffering from asthma

OBJECTIVE

A link between the upper and lower airways has been convincingly demonstrated both in health and disease. To what extent the nose may be involved in children's asthma, has so far not been thoroughly investigated. In this study, we compared symptoms and signs from the upper airways in children with asthma and in children without to find out more about this.

METHODS

The study group included 27 asthmatic children, the control group 29 age and sex-matched healthy volunteers. The children were investigated by a senior ENT-specialist. Their parents completed questionnaires about symptoms and signs of upper airway disorders. Skin prick tests, total IgE, acoustic rhinometry, and an X-ray of the epipharynx were performed. The data from the groups were compared.

RESULTS

Nasal blockage, mouth breathing, day time sleepiness, apnoeas, itching, sneezing, and hearing impairment were more prevalent in asthmatics compared with controls (p<0.05). For nasal blockage the mean VAS-scores were 52.4 and 30.6 for asthmatics and controls, respectively. For daytime sleepiness the corresponding figures were 34.6 and 23.1. The adenoid-nasopharynx-index was larger, indicating reduced palatal airway in the former compared with the latter (p<0.05).

CONCLUSIONS

As the site of upper airway obstruction in asthmatic children appears to be the epipharynx, the adenoids may play a key-role.

Characterisation of Staphylococcus aureus nasal and skin carriage among patients undergoing haemodialysis treatment

The aim of the study was to investigate the rate of Staphylococcus aureus nasal and skin carriage in patients undergoing haemodialysis. The cultured staphylococcal isolates were subsequently characterized by molecular methods. The study group comprised 43 haemodialysed patients from whom nasal and skin swabs from the vascular access sites were collected. The identification of staphylococcal isolates and antibiotic susceptibility testing were performed on the basis of conventional diagnostic procedures. The staphylococci were further characterized using Pulsed-Field Gel Electrophoresis (PFGE). S. aureus was cultured from 12 (27.9%) patients. Only one (8.3%) patient was colonized with the microorganism both in the anterior nares and the vascular access site representing a single strain, as evidenced by PFGE analysis. Antibiotic susceptibility testing identified one (7.6%) methicillin-resistant S. aureus (MRSA) strain. PFGE typing identified several S. aureus genotypes with the lack of one specific strain responsible for colonization. However, it should be noted that among two (A and D) PFGE patterns genetically indistinguishable and closely related isolates (two isolates for each pattern) were identified. The obtained results revealed a relatively low rate of S. aureus carriage accompanied by low methicillin resistance rate and a significant genetic diversity of cultured isolates with the lack of one predominant strain responsible for colonization.

Rhinologic manifestations of ectodermal dysplasia

BACKGROUND

The Ectodermal Dysplasias (ED) are a group of uncommon genetic disorders characterized by deficient development of tissues derived from ectoderm and mesoderm. Abnormalities of the respiratory epithelium prevent normal mucociliary function. We explored the prevalence and severity of sinonasal features in affected individuals.

METHODS

Thirty-four subjects with ED were evaluated. A focused history and thorough nasal examination including flexible nasopharyngoscopy were performed. Patients and caregivers rated the severity of rhinologic symptoms with a standard scale. Standardized smell tests were also performed.

RESULTS

The study included 21 males and 13 females whose mean age was 18.8 years (range, 4 months to 85 years). The majority (79%) had Hypohydrotic ED. Nearly half of the individuals evaluated reported moderate to severe nasal obstruction. Allergic symptoms were present in 44% of individuals whereas 41% had a history of sinusitis. Nasal concretions were significantly more troublesome in those aged 15 and under (p = 0.028). Eighteen percent had undergone sinonasal surgery. On examination, normal intranasal structures were identifiable in all patients. However, dry mucosae, prominent crusts, and concretions were found in most (79%). A deviated nasal septum was present in 23% of individuals and a saddle nose deformity in 18. Smell tests were normal for age in all subjects.

CONCLUSION

Rhinologic issues are prevalent and problematic in individuals with ED. Management should focus on humidification, nasal debridement, and tailored therapy for allergic rhinitis and sinusitis. Increased awareness of the sinonasal concerns in ED will facilitate diagnosis and improve the care of these patients.

Upper respiratory tract involvement of sarcoidosis in the Turkish population

PRINCIPLES AND METHODS

Upper respiratory tract (URT) involvement is rare in sarcoidosis. In this descriptive study, we retrospectively evaluated the clinical and demographic features of 12 (2.19%) patients with URT involvement out of the 546 sarcoidosis patients with follow-up visits at our center within the last 40-year period.

RESULTS

Out of the 546 patients, 12 (2.19%) had upper respiratory tract involvement, 5 (0.91%) had laryngeal involvement, 4 (0.73%) had sinonasal tract involvement, 2 (0.36) patients had salivary gland involvement, and 1 patient had tonsillary involvement. The number of stage 0 subjects among other sarcoidosis patients was significantly lower than that among those with URT involvement.

CONCLUSIONS

URT involvement is rarely diagnosed in patients with systemic sarcoidosis. The most common site for URT involvement among the Turkish population is the larynx, followed by the sinonasal tract.

Yearly incidence of rhinitis, nasal bleeding, and other nasal symptoms in mature women

OBJECTIVES/HYPOTHESIS

To evaluate, by a prospective questionnaire study, the incidence of spontaneous nasal pathology in mature women over a 12-month period, in particular nasal bleeding and the relationships of these symptoms with various factors.

METHODS

Participants were drawn from a sample of 12,735 adult French volunteers participating in a study of antioxidant nutrients ("SU.VI.MAX"); 3500 women aged 50-64 years were randomly selected from good responders in the SU.Vl.MAX population. The responses of 2197 women were analysed.

RESULTS

Nearly 70% of subjects reported at least one episode of rhinitis, with a mean (SD) of 1.88 (2.17) episodes per subject. Rhinitis was related to passive exposure to tobacco smoke (adjusted odds ratio [OR] 1.31, 95% CI 1.05-1.63), menopause (OR 1.47, 95% CI 1.16-1.88), and occupational exposure to vapours or dusts (OR 1.55, 95% CI 1.01-2.37). Nasal bleeding was reported as traces of blood by 16.5% of subjects, and as epistaxis (significant nasal bleeding) by 7.6%. Both symptoms were related to passive exposure to tobacco smoke (OR 1.63, 95% CI 1.22-2.19; OR 1.56, 95% CI 1.05-2.32, respectively) but not to use of systemic or topical medication.

CONCLUSION

A substantial number of mature women experience nasal symptoms during the course of a year. Rhinitis and nasal bleeding were correlated with passive exposure to tobacco smoke.

[The cutaneous leishmaniasis of the face in Gafsa area, Tunisia]

The cutaneous leishmaniasis is a frequent affection in Tunisia. In the Gafsa region it is a endemoepidemic infection. Our prospective study was carried out on 225 cases of cutaneous leishmaniasis of the face collected over two years in the outpatients' department of dermatology at Gafsa hospital. The aim of our study was to know more about the evolutive epidemio-clinical particularities of the cutaneous leishmaniasis of the face. The relative frequency of the cutaneous leishmaniasis of the face for the new patients reached 5%. An equal distribution between the two sexes was noted. The average age of our patients was 24 years old and 6 months old with extremes ranging from 3 months to 77 years. The nodular and ulcerated forms were the most frequent (35.3%), followed by impetiginoid forms (23%), then the lupoid forms (15%). The papular form was quite frequent (13%). Impetiginoid lesions occurred frequently in the child. Lupoid lesions appeared particularly on the nose. The complicated forms: the cutaneuos necrosis or erysipelas of the face appeared after intralesional injections of meglumine antimoniate (Glucantime). The intramuscular meglumine antimoniate was used in 172 patients, among them 47 needed two treatments or more because of a particular resistance of the lesions of the face. The pimple of Gafsa, term initially used for ulcerated skin nodules, was actually characterised by a lesional polymorphism. The prognosis was good however the risk of in aesthetic scar of the face was important.

Seasonal variations in rhino-cerebral Mucor infection

OBJECTIVES

Rhino-orbito-cerebral mucormycosis (ROCM) is an uncommon, potentially lethal infection that occurs mostly in immunocompromised hosts. The seasonal occurrence of ROCM was studied in two of Israel's largest medical centers.

METHODS

A total of 36 patients were seen during a 25-year period in this retrospective bi-institutional cohort study. Meteorologic data were obtained and analyzed for a possible linkage of infection with precipitation and temperature.

RESULTS

Twenty-one of the 36 patients (58%) presented between the months of August and October, and 27 patients (75%) presented between the months of August and December. A peak incidence of ROCM was noted in the month of September (13/36 patients; 36%). No association was noted between meteorologic conditions and the incidence of ROCM infection.

CONCLUSIONS

A consistent seasonal peak was observed in ROCM. Heightened awareness is important for early recognition and treatment of this disease.

Staphylococcus aureus and MRSA nasal carriage in general population

OBJECTIVE

Assessment of Staphylococcus aureus (S. aureus) and MRSA nasal carriage in our general population.

DESIGN

Cross-sectional analytical study.

PLACE AND DURATION OF STUDY

A private Pathology Laboratory in Lahore city from January 2002 to December 2003.

MATERIALS AND METHODS

Nasal swabs were obtained from the apparently healthy persons accompanying the patients attending the laboratory. These swabs were inoculated on blood and mannitol salt agar plates and incubated at 37 degrees C. The isolate(s) were identified as S. aureus on the basis of colony morphology, Gram staining, catalase and coagulase tests. Sensitivity to Oxacillin was determined using standard Kirby Bauer technique.

RESULTS

Nasal swabs from 1660 subjects from the community were studied. Out of these samples, a total of 246 (14.82%) samples were positive for growth of S. aureus (nasal carriers of S. aureus). Out of 246 S. aureus isolates, 48 (19.51%) isolates were methicillin resistant S. aureus (MRSA). Nasal carriage was higher in males (15.47%) as compared to females (13.26%), in urban areas (16.99%) as compared to rural areas (11.32%) and in the year 2002 (16.02%) as compared to year 2003 (13.08%). However, the difference was significant only for the urban vs. rural comparison (p<0.05). MRSA isolates were also significantly higher among S. aureus isolates from the nasal cavities of urban subjects (22.98%) as compared to rural ones (11.11%). Maximum nasal carriage was present in the age group upto 9 years (20.23%) with decrease in the age groups 10-19, 20-29 and 30-39 years followed by small rise in the older subjects.

CONCLUSION

The nasal S. aureus carriage as well as methicillin resistance among these isolates are more common in urban community.

Staphylococcus aureus nasal carriage in patients on haemodialysis: role of cutaneous colonization

We performed a prospective study of Staphylococcus aureus nasal carriage in patients on chronic haemodialysis to determine the role of cutaneous colonization in the aetiology of recurrent nasal colonization. From February 2000 to September 2001, 71 patients on chronic haemodialysis in the dialysis unit at a university hospital were screened monthly for S. aureus nasal carriage. Carriers received nasal mupirocin for five days and were tested for nasal and cutaneous carriage two days later and monthly thereafter. Using genotyping results, recurrence was defined as relapse if pretreatment and subsequent nasal isolates were clonally identical; if the isolates were different, it was considered recolonization. Thirty-nine patients (55%) were nasal carriers: 11 initially and 28 during follow-up. Among the mupirocin-treated patients, the eradication of S. aureus nasal carriage rate was 88.5%. Nasal recurrence was documented in 17 patients (43.5%), and S. aureus nasal strains were available for molecular typing in 14 patients with a total of 23 recurrence episodes. On the basis of pulsed-field gel electrophoresis analysis, 16 (70%) recurrence episodes were considered relapses and seven were considered (30%) recolonizations. Among the episodes of relapse, prior cutaneous colonization was detected in only three cases. In haemodialysis patients, the majority of nasal carriage recurrences after mupirocin therapy were due to relapses. Cutaneous colonization does not appear to be relevant in the development of these relapses.

Investigation of nasal disease in the cat--a retrospective study of 77 cases

A retrospective study was undertaken to determine the prevalence of different diseases in cats referred for investigation of chronic nasal disease, to identify historical, clinical and diagnostic features which may assist in making a diagnosis, and to provide information pertaining to outcome in these cats. Diagnoses included neoplasia (30 cases), chronic rhinitis (27), foreign body (8), nasopharyngeal stenosis (5), Actinomyces infection (2), nasal polyps (2), stenotic nares (2), and rhinitis subsequent to trauma (1). The most common neoplasia was lymphosarcoma (21 cases), with a median survival of 98 days for cats treated with multiagent chemotherapy. Cats with neoplasia were older on average than the other cats, and were more likely to be dyspnoeic and have a haemorrhagic and/or unilateral nasal discharge than cats with chronic rhinitis. Cats with neoplasia were more likely to have radiographic evidence of nasal turbinate destruction, septal changes, or severe increases in soft tissue density than cats with chronic rhinitis. It was unusual for cats with diseases other than neoplasia to be euthanased as a result of their nasal disease.

Radiographic signs in cats with nasal disease

Radiographic signs in 64 cats that had radiography as part of the diagnostic work-up for suspected nasal disease were reviewed in a blinded fashion. Final diagnoses in these cats were rhinitis in 27, primary nasal neoplasia in 21 and non-nasal disease in 16. The signs with highest predictive value for nasal neoplasia were displacement of midline structures (73%), unilateral generalised soft tissue opacity (70%), unilateral generalised loss of turbinate detail (69%) and evidence of bone invasion (64%). The only radiographic finding that occurred more frequently in cats with rhinitis was a nasal cavity within normal limits, and the predictive value of this sign was only 38%. Radiographic signs in cats with nasal neoplasia are similar to those reported in dogs, whereas the radiographic signs in cats with rhinitis are variable and non-specific, and may be absent.

Influence of heavy traffic, city dwelling and socio-economic status on nasal symptoms assessed in a postal population survey

BACKGROUND

The association between social position, living environment and nasal symptoms is inconsistent. We wanted to test how living environment, occupation and social position were associated with nasal symptoms.

METHODS

In a postal survey study of a random sample of 12,079 adults, aged 20-59 years living in the southern part of Sweden the relationship between nasal symptoms, socio-economic status and environmental factors was analysed.

RESULTS

The response rate was 70% (n = 8469) of whom 33% reported significant nasal symptoms. Nasal discharge, thick yellow discharge, a blocked nose, sneezing and itching were strongly associated with living close to heavy traffic or living in cities. Most of the nasal symptoms provoked by extrinsic factors were more frequently reported among subjects who lived close to heavy traffic and in cities. Apart from thick yellow discharge and nasal symptoms provoked by damp/cold air which were more common in the socio-economic position "low" no relation to the socio-economic group was found. The prevalence of self-reported hay fever was neither affected by site of living nor by socio-economic status. Nasal symptoms evoked by "allergic" factors were linked to asthma but symptoms evoked by non-allergic factors were linked to chronic bronchitis/emphysema CBE.

CONCLUSIONS

To conclude, we found a strong relation between geographical site and the prevalence of self-reported nasal symptoms which emphasizes the environment as a risk factor for nasal symptoms. Only by merging the socio-economic groups into "low" and "middle/high" an association to nasal symptoms was apparent. Nasal symptoms evoked by "allergic" factors were linked to asthma but symptoms evoked by "non allergic factors" were linked to CBE.

The correlation between septal deviation and concha bullosa

OBJECTIVES

To investigate the incidence of concha bullosa (CB) in patients with septal deviation and the correlation between the angle of deviation and degree of pneumatization. Study and design This study was designed as a prospective trial.

METHODS

Computerized tomography scans of the paranasal sinuses of 100 consecutive patients with the chief complaint of nasal obstruction and the diagnosis of septal deviation were taken. CB, sinus diseases, and septal deviation angles were recorded.

RESULTS

Angles of deviation ranged between 3 and 25 degrees (mean, 13.0 +/- 4.1 degrees). The mean of angle of deviation in cases with CB and in cases without CB was 13.0 +/- 4.0 and 13.0 +/- 4.2 degrees, respectively. No statistical difference was found between them (P > 0.05). Pneumatization of the contralateral CB was statistically significantly higher than that of ipsilateral CB (P < 0.05).

CONCLUSION

Septal deviation does not appear to give rise to the formation of CB, but augments the pneumatization of the middle turbinate depending on the degree of deviation angle.

[Oto-rhino-laryngology and geriatrics in the Ivory Coast]

Geriatrics medicine develops more and more as a specialized branch of medicine. We report a prospective study of 69 cases of geriatric patients hospitalized in the ENT department of Treichville's teaching hospital from 1996 till 2001. The frequency of hospitalization was estimated at 6.5%. The cohort consisted of 48 males (69.5%) and 21 females (30.5%) with an overall average age of 66.5 years. The majority of the patients lived in the city of Abidjan (61%) with a low socio-economic level (54%). 50.7% were married and 75.4% lived in a house-bold of several persons. The main lesions were at the level of the larynx (36.2%) and nose and sinuses (21.7%) cancers (52%) were more frequent. The patients were little dependent (84%), however 11.6% presented with psychological troubles. Associated pathologies were identified in 18.8% of case. The age, dependence and pathology determined the average duration of stay and the mode of exit. Mortality, of tumoral cause (cancer of the larynx), was estimated at 11.6%. An improved service requires a mutli-disciplinary approach an ORL-based presentative programme and prospective multicentre studies.

Ocular, nasal, dermal and general symptoms among commercial airline crews

OBJECTIVE

To study symptoms among a commercial cabin crew, in relation to personal risk factors, perceived psychosocial work environment, occupation, and work on intercontinental flights, with exposure to environmental tobacco smoke (ETS).

METHODS

A standardized questionnaire (MM 040 NA) was mailed in February-March 1997 to all Stockholm aircrew on duty in a Scandinavian flight company ( n=1,857), and office workers from the same company ( n=218). During this time, smoking was allowed only on intercontinental flights. The participation rate was 81% ( n=1,513) of the aircrew, and 77% ( n=168) of the office group. Statistical analysis was performed by multiple logistic regression analysis, keeping age, gender, atopy, current smoking, occupation, and perceived psychosocial work conditions simultaneously in the model.

RESULTS

The most common symptoms among the aircrew were fatigue (21%), nasal symptoms (15%), ocular symptoms (11%), dry or flushed facial skin (12%), and dermal hand symptoms (12%). The aircrew had more nasal (odds ratio (OR) = 3.12), throat (OR=5.75), and dermal symptoms on the face (OR=2.03), and hands (OR=3.68), than the office workers. The aircrew with a history of atopy had an increase of most symptoms (OR=1.5-3.8), but age, gender, or smoking was not associated with symptoms. Perceived stress due to excess of work was associated with fatigue (OR=7.33), feeling heavy-headed (OR=9.52), headache (OR=5.10), and facial dermal symptoms (OR=3.75), while those crew with better work control and work satisfaction had less fatigue. For most symptoms, there were no differences between different categories onboard, but pilots had fewer ocular (OR=0.28) nasal (OR=0.52), and dermal hand symptoms (OR=0.39). Airline crew that had been on an intercontinental flight the previous week had more complaints of fatigue (OR=1.87), heavy-headedness (OR=1.89), and difficulties concentrating (OR=3.22).

CONCLUSION

There was an association between symptoms and work stress, lack of influence on working conditions, atopy, and work on intercontinental flights where smoking was allowed. In view of the increase of civil aviation, the working conditions for aircrews need further attention.

A long-term study of 277 cases of equine sinonasal disease. Part 1: details of horses, historical, clinical and ancillary diagnostic findings

The clinical and ancillary diagnostic findings in equine sinnasal disease were studied. The diagnoses in 277 referred (1984-1996) cases of equine sinonasal disease included the following (% all cases): 67 cases (24.2%) primary sinusitis, 61 (22.0%) dental sinusitis, 37 (13.4%) sinus cysts, 22 (7.9%) sinonasal neoplasia, 21 (7.6%) progressive ethmoid haematoma, 17 (6.1%) sinonasal trauma, 13 (4.7%) sinonasal mycosis, 11 (4.0%) rostral maxillary cheek tooth infection, 7 (2.5%) sinonasal polyps, 7 (2.5%) cases of nasal epidermal inclusion cysts and 14 (5.1%) miscellaneous sinonasal disorders. Many disorders showed similar clinical signs including nasal discharge (present in 88% of all cases) and facial swelling (46%). Most disorders were chronic, with a median duration of signs of 12 weeks (range 3 days- 6 years) prior to referral. Sinus cysts and sinonasal neoplasia were significantly (P<0.05) more frequently associated with gross distortion of the nasal passages and facial bones than the other sinonasal disorders. Endoscopic changes were detected per nasum in 91% of cases, but contributed to the exact diagnosis in only 20%. Radiography revealed abnormalities in 81% of cases but was diagnostically useful in only 36%. Sinoscopy was diagnostically useful in 70% of the 61 cases where used.

[Human nasal myiasis due to Oestrus ovis]

One case of human nasal myiasis caused by second and third instar larvae of Oestrus ovis was observed in Lille (North France). Oestrosis is a common myiasis of sheep and goats in Mediterranean and Tropical countries. The authors examine the oestrosis pathogenesis in the usual host (sheep) or in humans, and analyse the epidemiology, the symptomatology and the treatment of human oestrosis.

Nasal, eye, and skin irritation in dockyard painters

OBJECTIVES

To determine whether the risk of irritant symptoms in painters is related to their exposure to paint.

METHODS

The prevalences of skin, eye and nasal symptoms were compared in 260 United Kingdom and 109 Chinese dockyard painters, 539 British community controls, and 255 Chinese dockyard controls, relative to their exposure to paints.

RESULTS

Painters showed an excess of irritant symptoms compared with controls. Adjusted relative risks (RRs) (95% confidence interval (95% CI) were: for skin irritation 1.58 (1.19 to 2.08) in British painters and 2.68 (1.73 to 4.09) in Chinese painters; for eye irritation, 1.41 (0.98 to 2.05) and 3.01 (1.90 to 4.76); and for nasal irritation, 1.53 (1.10 to 2.14) and 6.73 (3.53 to 12.82), respectively. Exposure duration-response relations were found for these symptoms; the risks decreased with time after exposure ended.

CONCLUSIONS

Irritant symptoms occur more often in dockyard painters than in controls, and this is likely to be a response to exposure to paint.

Prevalence of Pneumonyssoides caninum infection in dogs in Sweden

A prospective study of 474 dogs, 145 cats, and 66 wild red foxes submitted for necropsy to the Departments of Pathology at the National Veterinary Institute and the Swedish University of Agricultural Sciences, Uppsala, Sweden, was conducted to examine for the presence of Pneumonyssoides caninum, the canine nasal mite. Pneumonyssoides caninum (P. caninum) was found in 95 (20%) of the dogs but in none of the cats or foxes. The median number of P. caninum mites per infected dog was 13 (range, 1 to 250). Dogs older than 3 years of age were more often infected with P. caninum than younger dogs, and large-breed dogs were more often infected than small-breed dogs. No sex predisposition was found.

Laryngeal and nasal involvement in pemphigus vulgaris

BACKGROUND

The presence of lesions of pemphigus vulgaris in the larynx and nasal cavity has been reported in individual case reports. However, the frequency with which these sites are involved is not known.

OBJECTIVE

Our purpose was to investigate the incidence of laryngeal and nasal disease involvement in patients with pemphigus vulgaris.

METHODS

This was a retrospective analysis conducted in a referral private practice in an academic department of dermatology. A total of 53 sequential patients with pemphigus vulgaris diagnosed by clinical, histologic, and immunofluorescence criteria were selected on the basis of having been treated by one of us (J. C. B.) during most of their illness. Patients' charts were reviewed for documentation of laryngeal and nasal symptoms, ear/nose/throat evaluation, and response to treatment.

RESULTS

Twenty-six (49%) of the patients complained of laryngeal or nasal symptoms at some time during the course of their disease. Twenty-one patients had laryngeal symptoms and 12 had nasal symptoms. More than 80% of patients with laryngeal or nasal symptoms had evidence of pemphigus involvement based on ear/nose/throat examination or rapid response to increased doses of corticosteroids, and 2 patients had candidiasis confirmed by fungal culture.

CONCLUSION

These observations indicate that laryngeal and nasal symptoms are common in pemphigus vulgaris. In the majority of cases, this appears to be a result of involvement with the disease or with candidiasis.
