ABSTRACT

AIM: To investigate the role of smoking, alcohol, coffee consumption, demographic factors, toxic agents, and occupation in laryngeal carcinogenesis. MATERIALS/METHODS: A case-control study included 70 patients with histologically confirmed laryngeal cancer and 70 controls with non-neoplastic conditions unrelated to diet/smoking/alcohol. Relative risk, odds ratio (OR), and 95% confidence intervals were estimated using multiple logistic regression. RESULTS: Current smokers had 19.46 OR of laryngeal cancer compared to non-smokers (p = 0.006). The respective OR for alcohol consumption was 3.94 (p = 0.006). While the risk increased in heavy drinkers, there was no difference in duration of alcohol consumption. There was a strong and consistent relation between laryngeal cancer and the consumption of Greek/Turkish coffee cups/day (p = 0.002, OR = 1.77). Diesel exhaust fumes also seemed to increase the risk of laryngeal cancer, although the association was found to be no longer significant after analysis with logistic regression. CONCLUSION: The present study confirmed the relation of smoking and alcohol with laryngeal cancer. However, other factors such as coffee and diesel exhaust fumes may play an important role in laryngeal carcinogenesis.

ABSTRACT

The case is presented of a 73-year-old male with a history of right-sided nasal obstruction, hyponasal speech and three episodes of recurrent epistaxis. On examination, there was a tumour in the right nasal cavity. Computed tomography showed a mass in the right nasal cavity extending to the right maxillary sinus, ethmoidal cells and right sphenoid sinus. The patient underwent a functional endoscopic removal of the tumour. Biopsy revealed a small cell neuroendocrine carcinoma. This is an extremely rare tumour of the nasal cavity and sinuses. Because of the aggressive behaviour of this tumour, he was also treated with combined chemotherapy and radiation. Ten months later, he remains free of disease.

ABSTRACT

OBJECTIVE: To determine whether tympanostomy tube insertion has benefit, compared with simple myringotomy, in children with otitis media with effusion who receive concurrent adenoidectomy as treatment for obstructive sleep apnoea syndrome caused by adenoid hypertrophy. METHODS: Fifty-two children older than three years with obstructive sleep apnoea syndrome were randomly assigned to receive either adenoidectomy plus tympanostomy tube insertion (group one, n = 25) or adenoidectomy plus myringotomy (group two, n = 27). Pre- and post-operative health-related quality of life was assessed using the otitis media-6 (OM-6) tool, and audiological outcomes were recorded six and 12 months post-operatively. RESULTS: Group one showed better quality of life scores six months post-operatively (score difference -0.38, confidence interval -0.65 to -0.10) but not 12 months post-operatively (score difference -0.23, confidence interval -0.76 to 0.11), compared with pre-operative values. Audiological outcomes did not differ significantly at either time point, compared with pre-operative values. CONCLUSION: Tympanostomy tube insertion confers a short term benefit, compared with simple myringotomy, in children older than three years with otitis media with effusion who receive concurrent adenoidectomy as treatment for obstructive sleep apnoea syndrome. Further studies are necessary to identify which of these children will receive long-lasting benefit from tympanostomy tube insertion.

ABSTRACT

BACKGROUND: Endoscopic sinus surgery has become popular for the management of sinonasal inverted papillomas (IP). OBJECTIVE: The purpose of this report is to review our 13 years of experience in managing IPs. METHODS: Retrospective chart study. Sixty-seven patients with sinonasal IPs were treated in our department from 1991 to 2004. Seventeen were managed using an endonasal non-endoscopic approach, 39 endoscopically, 8 through external techniques, and the remaining 3 using a combined approach. RESULTS: After 1994, as we gained experience using endoscopic sinus surgery, most cases were treated endoscopically. In only 3 cases, where the tumour attachment site was in the lateral / anterior wall of the maxillary sinus and in the lateral wall of the frontal sinus, could the lesions not be accessed by extended endoscopic techniques, and an appropriate combination with external methods was required. The mean follow up period was 91 (range, 36-146) months. The recurrence rate was 59% using an endonasal non-endoscopic approach, 12.5% using an external incision, and 12.8% using endoscopic techniques. Average time to recurrence was 15 months. CONCLUSION: Our findings suggest that endoscopic sinus surgery for sinonasal IP is a viable approach, with a low rate of recurrence and minor morbidity. Complete tumour resection at the site of attachment, including a surrounding rim of normal mucosa and drilling the underlying bone, is the key to successful treatment when it is combined with the preservation of healthy tissue. Non-endoscopic endonasal surgery is no longer a treatment option because the recurrence rate is too high.

ABSTRACT

We present a case of a 34-year-old woman with myoepithelial carcinoma of the retromolar area. Myoepithilial carcinoma is a rare tumor of small salivary glands most usually located in the parotid gland. The major differential diagnosis of myoepithelioma is from pleomorphic adenoma. Little is known about the clinical and biological behavior and the prognosis of myoepithelial carcinoma and there is no consensus for its treatment. It is considered a low-grade malignancy; it sometimes shows aggressive behavior and may locally recur. Our patient was treated successfully with wide-local resection and remained free of disease for 6 months.

ABSTRACT

The study aimed to investigate the expression of p53, Bcl-2 and Ki-67 in relation to the histologic and nuclear qualitative and spatial characteristics of chronic rhinosinusitis with polyposis (CRP). Imprint smears obtained from surgically removed nasal polyps of 20 patients were studied. The polyps were classified according to their histological characteristics as: hyperplasia (simple and pronounced) and squamous metaplasia. The expression of p53, Bcl-2 and Ki-67 was assessed by immunocytochemistry. DNA spatial distribution and nuclear orientation were studied by staining with propidium iodide and examined by confocal microscopy. Positive immunoreaction for p53, Ki-67 and Bcl-2 was observed in 50, 65, and 50% of polyp's smears, respectively. For each diagnosis, the rates were simple hyperplasia 60, 80 and 30%, pronounced hyperplasia 80, 100 and 40%, metaplasia 0, 0 and 100%, respectively. Abnormal chromatin distribution and nuclear disorientation was observed in three cases of pronounced hyperplasia combined with positive immunoreaction for Ki-67 and p53 and negative immunoreaction for Bcl-2. CRP demonstrated different proliferation and apoptotic rates, according to their histology. Nuclear characteristics observed by confocal microscopy are associated with the immunocytochemical markers of proliferation and apoptosis.

ABSTRACT

PURPOSE: To examine the acoustic results over a long period of time, in patients who underwent ossiculoplasty with Plastipore, and to report the percentage of prosthesis extrusion and factors related to the prognosis. PROCEDURES: Forty-two patients, who underwent ossiculoplasty with Plastipore, were studied. Patients were followed up for the next 14 years. The surgical procedures were classified as: tympanoplasty, tympanoplasty with mastoidectomy with canal wall up, and tympanoplasty with mastoidectomy with canal wall down. A successful hearing result was defined as a postoperative air-bone gap (ABG) of 20 dB or less. RESULTS: Successful results were seen in 65% of our patients, 68.8% with a partial ossicular replacement prosthesis (PORP) and a 62.5% success rate with a total ossicular replacement prosthesis (TORP). The mean value for ABG improvement was 25.5 dB. Prosthesis extrusion occurred in 4.7%. CONCLUSIONS: The ossiculoplasty-Plastipore technique leads to good hearing results and a low percentage of prosthesis extrusion in long-term follow-ups.

ABSTRACT

AIM OF THE STUDY: To evaluate the ability of VEMP to disclose spatial dissemination of Multiple Sclerosis. MATERIALS AND METHODS: Forty-six MS patients with auditory and/or vestibular symptoms were studied. Patients were divided in two groups. Group 1 included 24 patients with brainstem MRI findings, and Group 2 included 22 patients without MRI findings. VEMP and BAEP have been recorded and assessed. RESULTS: Abnormal p13n23 wave was observed in 50%, while unilateral absence or bilateral delay of the n34p44 in 43% of the patients. The overall diagnostic value considering abnormal cases suggested by both first and second VEMP waves was increased to 71%. Statistically significant differences revealed between patients and controls for p13 latency (p=0.018). The p13n23 was abnormal in 7 patients, although MRI scanning did not reveal brainstem lesions. In 9 out of 18 MS patients suffering from unilateral hearing loss, n34p44 was present in the unaffected ears and absent in the affected side, although p13n23 was normal. CONCLUSION: Abnormal VEMP imply the presence of lesions undetected by MRI neuroimaging, which verifies the diagnostic value of the method. Unilateral absence of n34p44 complex was related with sensorineural hearing loss, supporting the hypothesis that n34p44 is of cochlear origin.

ABSTRACT

OBJECTIVE: To validate a disease-specific health related quality of life (HRQOL) instrument for children with chronic suppurative otitis media with or without cholesteatoma. METHODS: Caregivers of 45 children with chronic suppurative otitis media, who were offered an operation (tympanoplasty or radical mastoidectomy) in a tertiary children's hospital, were administered a 5-item quality of life survey (COM-5) The COM-5, which is a modified version of OM-6, was administered four times: few weeks and few days before operation and six months and one year postoperatively. Psychometric characteristics and more specifically test-retest reliability, internal consistency, construct validity, and responsiveness to clinical change of the COM-5 score were the main outcome measures. RESULTS: Median COM-5 score was 2.6 (1- to 7-point scale) with higher scores indicating poorer quality of life. Test-retest reliability was good (interclass correlation coefficient=0.73) Construct validity was demonstrated by significant correlations between COM-5 score and global ear-related quality of life (R=-0.485), between physical suffering and ear-related physician visits (R=0.41) and between caregiver concerns vs ear-related physician visits (R=0.44). The mean change in COM-5 score after successful tympanoplasty was 1.1 and correlated well with the change of global ear-related quality of life rating (R=-0.545) as well as with the degree of clinical change reported by the caregiver (R=0.494). The mean standardized response was 1.3 after tympanoplasty indicating the instrument's large responsiveness to clinical change after this procedure, but only 0.7 after radical mastoidectomy. CONCLUSIONS: The COM-5 is a valid, reliable and responsive instrument. Apart from its satisfactory psychometric characteristics, it can be easily administered in caregivers of children who require a tympanoplasty due to chronic suppurative otitis media.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate hearing in a population of industrial workers exposed to occupational noise by using both conventional and extended high-frequency (EHF) audiometry, and to compare our results with the findings from a control group. METHODS: A total of 139 industry workers exposed to noise were examined over a period of two years and 32 healthy subjects were used as controls. Conventional audiometry in the frequency range 0.25-8 kHz and EHF audiometry in the frequency range 9-20 kHz were performed. RESULTS: Thresholds in the noise-exposed group were higher than in the control group for both standard and extended high frequencies, but variability was greater in EHF. Larger differences were found in the 4,000-18,000 Hz frequency region, and especially in the 12,500-18,000 frequency zone. A statistically significant correlation between the elevation of puretone thresholds and time of exposure was found across all frequencies (from 250 to 20,000 Hz), with the exception of 10,000 Hz. CONCLUSIONS: EHF audiometry is a useful adjunct to conventional audiometry in the audiological assessment of subjects exposed to occupational noise. This test performs well in the frequency range 12,500-18,000 Hz, but there is greater variability in the results compared with conventional audiometry.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate expression of the neuropeptides substance P, vasoactive intestinal peptide and heat shock protein 70 in the nasal mucosa cells of patients with seasonal allergic rhinitis, in order to obtain more information on the pathophysiological and immunological role of these markers in allergic rhinitis. MATERIAL AND METHODS: Nasal epithelium specimens obtained from 42 patients with allergic rhinitis were studied, using Shandon's Papspin liquid-based cytology method. Smears were immunostained with antibodies against substance P, vasoactive intestinal peptide and heat shock protein 70, and the results were correlated with the clinical features of seasonal allergic rhinitis. RESULTS: A positive reaction for substance P, vasoactive intestinal peptide and heat shock protein 70 was observed in 73.8, 66.7 and 69.0 per cent of the allergic rhinitis mucosal smears, respectively. The Pearson chi-square test showed that 40.5 per cent of the immunostained smears had a positive reaction for one or two of the markers studied (i.e. substance P, vasoactive intestinal peptide or heat shock protein 70), and that 47.6 per cent of the smears had a positive reaction for all the markers (p < 0.0001). CONCLUSIONS: We found a high level of expression of substance P and vasoactive intestinal peptide in the nasal mucosa smears of patients suffering from allergic rhinitis. This indicates a role for these neuropeptides in the neuroregulation of immunity and hypersensivity in this disease. Furthermore, expression of heat shock protein 70 may contribute to the development of allergic rhinitis.

ABSTRACT

BACKGROUND: Vestibular Evoked Myogenic Potentials (VEMPs) are saccular responses to acoustic stimuli. They can be recorded from the sternocleidomastoid muscle ipsilaterally to the stimulated ear. Their reflex arc includes the ipsilateral vestibular nuclei. OBJECTIVE: To determine the usefulness of VEMPs in localising brainstem lesions. METHODS: We used VEMPs, Blink Reflex (BR) and Brainstem Auditory Evoked Responses (BAERs) to evaluate six patients presenting with acute ischaemic or haemorrhagic brainstem lesions, or basilar dolichoectasia. RESULTS: MRI in patient one revealed a dorsolateral medullary infarct on the right. VEMP amplitude was reduced ipsilaterally. The R2 BR component was delayed bilaterally upon stimulation of the affected side. Patients two and three had suffered a left lateral lower pontine infarct and a right lateral lower pontine haemorrhage. In patients four and five, MRA revealed dolichoectasia of the basilar artery exerting pressure on the lower lateral pons. VEMP amplitude was reduced ipsilaterally. Patient six had an ischaemic lesion in the right upper lateral pons. The R1, R2i and R2c BR components were delayed ipsilaterally. BAERs waves IV and V were absent on the right. VEMPs were normal. CONCLUSIONS: VEMPs are affected by lesions of the lateral lower pons and upper medulla. Our results suggest that they may be a useful addition in the localisation of such lesions.

ABSTRACT

Aim of this study was to investigate the clinical characteristics, management and prognosis of non-Hodgkin lymphomas of the nasal cavity and paranasal sinuses. Overall 12 patients with non-Hodgkin malignant lymphoma, at our Institute, were studied over an eight-year period from 1997 to 2005. Patients' data collected were age, sex, presenting signs and symptoms, histology, treatment, complications, and outcome. Also available were computerised tomography findings, and paraffin-embedded tissue bocks. Mean age was 62 years (range: 42-81), with a male dominance (male to female ratio: 7:5). Most patients had not presented any specific symptoms, such as nasal obstruction, headaches, epistaxis and facial swelling. Using immunocytochemistry on paraffin-embedded tissue sections, the predominance of large B-cell subtype was detected. Treatment administered: only radiotherapy (stage IEA) or in combination with chemotherapy (IIE-IVE). Of these patients, 5 died from the disease, 4 survived without disease, 2 survived with the disease, and one died of non-related causes. Non-Hodgkin's lymphomas are relatively rare. Early diagnosis, based mainly on tissue biopsy and computerised tomography, is essential in the management of non-Hodgkin lymphoma.

ABSTRACT

UNLABELLED: The effect of very low birth weight on otoacoustic emissions. OBJECTIVES: The aim of this study was to examine the effect of very low birth weight (VLBW) on the measurement of transiently evoked otoacoustic emissions (TEOAEs) in newborns. METHODS: TEOAEs were recorded in all VLBW newborns (birth weight < 1500 g) who were admitted in the Neonatal Intensive Care Unit of the Iaso Maternity Hospital, during a period of 1 year. Twenty-four VLBW newborns were included in the study. Their mean birth weight was 1283 g and they had mean gestational age 31.3 weeks. Forty full-term newborns with absence of any risk factor for hearing impairment were used as controls. RESULTS: TEOAEs were present in 97.5% of controls, but only in 79.2% of the VLBW group. Statistically significant differences were found between VLBW newborns and controls in most TEOAE measures. CONCLUSIONS: Increased rate of initial 'fail' in hearing screening, in conjunction with statistically confirmed lower TEOAE measures in VLBW newborns, justifies special care and long term follow-up for this group of newborns.

ABSTRACT

The remnants of the acoustic ossicles have been used in ossicular reconstruction during mastoid surgery for many decades. The present study assessed the status of the acoustic ossicles in 114 patients (57 with cholesteatoma and 57 without) during surgery for chronic otitis media using the operating microscope. In 52 cases, the ossicles (malleus and/or incus) were assessed using both the surgical and scanning electron microscope in order to reveal any erosions and compare the findings. From the 57 operated ears with cholesteatoma, 45 (79%) had ossicular erosion whereas 12 (21%) did not. In the group of 57 operated ears with chronic otitis media without cholesteatoma, 33 (58%) had ossicular erosion whereas 24 (42%) did not. This difference was statistically significant (p = 0.02). With regard to the 52 operated cases who were studied with both microscopes, in the cholesteatoma patients the surgical microscope was not able to reveal any ossicular erosions in 39% of the cases, whereas the scanning electron microscope revealed moderate or severe erosions in the same ears. This suggests that the operating microscope is not reliable enough to determine if ossicular remnants can be used in ossicular reconstruction following cholesteatoma surgery. There is a considerable risk that epithelia or other cholesteatoma particles remain in the areas of erosions that cannot be seen with the operating microscope. The use of such ossicular remnants may lead to cholesteatoma recurrence and failures in mastoid surgery. Therefore, autoclaving or alternative prosthesis may be considered in such cases.

ABSTRACT

OBJECTIVE: The identification of a reliable circulating tumor marker in squamous cell carcinoma of the head and neck (SCCHN) could assist in diagnosis and monitoring response to therapy. AIM: The aim of this study was to investigate the effectiveness of the serum tumor markers CYFRA 21-1, TPA-M, SCCA, and CEA. STUDY DESIGN: Serum levels of CYFRA 21-1, TPA-M, SCCA, and CEA were measured in 136 patients with a histologically proven SCCHN before and after treatment and in 125 healthy subjects, as controls. We evaluated the sensitivity and specificity of these tumor markers and to correlate their levels with tumor staging, grading, or performance status. RESULTS: The study showed that none of the above markers presented satisfactory specificity and sensitivity in early diagnosis. In comparison with the other markers, TPA-M was the most effective of all markers and indicated a positive correlation with the grade of differentiation and nodal status. A remarkable correlation between high levels of TPA-M and CYFRA 21-1 in advanced stages (III, IV) of cancer has been shown. CONCLUSIONS: All the tumor markers that were studied have significant limitations in the early diagnosis of cancer, but TPA-M and CYFRA 21-1 may have a role in monitoring the success of therapy and follow up of patients with SCCHN.

ABSTRACT

BACKGROUND: In contrast to the recommendations of the Joint Committee on Infant Hearing, neonatal hearing screening programs are still not universally available, and many countries implement elective screening in high-risk newborns. OBJECTIVE: To assess the failure rates of neonates in hearing screening and the relative importance of risk factors for hearing impairment, both in neonatal intensive care units and in well-baby nursery neonates. The impact on cost-effectiveness is also evaluated. SUBJECTS: In the current study, 25,288 newborns were assessed; 23,574 were full-term newborns in the well-baby nursery and 1,714 neonates were in neonatal intensive care units. METHODS: All neonates had a general examination (including assessment for congenital anomalies and related history) and were assessed using transient evoked otoacoustic emissions. All newborns were older than 36 weeks at examination and thus had reliable transient evoked otoacoustic emissions. RESULTS: From the 23,574 full-term neonates in the well-baby nursery, 23,123 (98.1%) passed the test and 451 failed (1.9%). Fifty-three of the 23,574 neonates (0.2%) had a risk factor for hearing impairment; 44 (83%) passed the test and 9 failed (17%). Family history of congenital hearing loss and congenital anomalies were the most frequent risk factors for hearing loss. From the 1,714 neonates in neonatal intensive care units, 1,590 (93%) passed the test and 124 failed (7%). Two hundred thirty-two of the 1,714 neonates (14%) had a risk factor for hearing impairment; 205 (88%) passed the test and 27 failed (12%). In neonatal intensive care unit neonates, toxic levels of ototoxic drugs, mechanical ventilation for more than 24 hours, prematurity, and low birth weight were the most frequent risk factors for hearing loss. Congenital anomalies/syndromes were the most important risk factors for failing screening in both the neonatal intensive care unit and the well-baby nursery, as they showed the highest risk of failing hearing screening. The second most important factor in neonatal intensive care unit newborns was low birth weight, and the third was prematurity in relation to the possibility of failing hearing screening. CONCLUSION: The present study found 575 neonates failing hearing screening of 25,288 tested newborns (2.3%). The fact that 78% of newborns who failed hearing screening were in the well-baby nurseries further supports the necessity of universal hearing screening instead of selective screening in neonatal intensive care units, even with the obvious impact on cost-effectiveness. Even if limited funding lead to selective screening in neonatal intensive care units, this should not be applied to high-risk newborns but to all neonatal intensive care unit neonates. Continuous assessment of risk factors and the related possibility of failing hearing screening are of paramount importance in designing hearing screening programs and refining the respective criteria.

ABSTRACT

Activation of telomerase, present in the vast majority of all human cancers, is associated with elongation of chromosomal telomeres and consequent cell immortalization. Telomere length homeostasis is a dynamic process governed by the negative feedback mechanism of the telomeric repeat binding factor 1 (TRF1) which inhibits the action of telomerase in telomerase-positive cells. In an attempt to investigate markers of tumour growth as possible prognostic indicators in laryngeal cancer, we studied the expression of TRF1 and of the proliferation marker Ki67 on 96 invasive squamous carcinomas of the larynx. A standard three step immunoperoxidase staining method was applied on paraffin sections incubated with appropriate polyclonal antibodies. The percentages of Ki67- and TRF1-immunopositive cancerous cells were calculated by image analysis. Univariate and multivariate statistical analysis of the staining results were performed in order to detect any association of the examined immunomarkers with the tumours' classical clinicopathological variables including nuclear morphometric features as well as with patients' disease-free survival. Ki67 immunostaining was positively linked with advanced patients' age, nodal involvement as well as presence of early recurrence. No relation was found between proliferative fraction and TRF1 immunoexpression. TRF1 was expressed in 55.2% of all cases and was positively linked only to tumour size. Multivariate statistical analysis revealed the presence of lymph nodal metastasis and Ki67 immunopositivity index > or = 20% as significant predictors of relapse. Increased Ki67 immunostaining appears to be a promising marker of tumour aggressiveness in laryngeal cancer. After one point at the tumour's natural history, the maintenance of tumour growth does not seem to depend on cell proliferation but on TRF1 immunoexpression. Whether the latter can be used for the identification of immortalized cells in every-day practice is worth investigating.

ABSTRACT

Various recognized prognostic factors in squamous cell carcinoma of the larynx influence the therapeutic option offered to an individual patient in order to extend the survival expectancy. Additional prognostic indicators are required in specific patient subgroups. We performed a retrospective study by using a standard immunohistochemical technique in order to evaluate the accumulation of cathepsin-D as possible prognostic marker of laryngeal squamous cell carcinoma. Formalin fixed, paraffin embedded tumor materials were obtained from a series of 64 patients with cancer of the larynx. Immunostaining was evaluated by computerized image analysis. Cathepsin-D immunostaining was observed in tumor parenchymal and stromal cells (31.25% and 37.5% of all cases respectively); it was found to be useful in defining patient subgroups with differences in relapse-free survival. Among patients with positive lymph nodes, those with cathepsin-D immunopositive tumor cells were in higher risk for relapsing (p = 0.0395). Although the classical prognostic factors of laryngeal carcinoma retain their predominance, cathepsin-D immunoreactivity may serve as an additional prognosticator in specific patient subgroups.

ABSTRACT

OBJECTIVES: To present a rare occurrence in ear, nose and throat practice of upper airway allergic edema from use of juice extracted from the fruit of Ecballium elaterium. INTRODUCTION: Ecballium elaterium is a plant indigenous to the Mediterranean region that bears the common name squirting cucumber. Many people in this region for the treatment of sinusitis use the juice of its fruit. However, allergy-prone patients after using it may sometimes present with edema at various sites of the upper respiratory tract. Otolaryngologists are frequently asked to diagnose and treat such an emergency situation. STUDY DESIGN: Retrospective review of the records of 42 patients with this condition during the last 4 years. METHODS: Patient records were retrospectively reviewed for age, sex, presenting symptoms, physical examination, and medical treatment. Seasonal distribution and data from the history of the patients were also considered. Skin prick and prick-to-prick testing to various allergens was performed in 12 patients. RESULTS: Most of the patients presented with localized swelling of the uvula and the nasal mucosa, whereas in the remainder of the patients various sites of swelling of the upper respiratory tract were observed. Skin tests elicited positive reactions to pollen weeds and to various fruits of the Cucurbitaceae family. Treatment of the patients with corticosteroids and antihistamines resulted in an uneventful recovery, and we did not need to resort to therapeutic modalities, such as intubation or tracheotomy. CONCLUSIONS: We think a further study of the pharmaceutical properties of the plant's fruit juice is needed, especially regarding its curative properties of rhinitis and sinusitis. However, adverse reactions in some patients with a positive history of allergy should always be considered.
