RESUMO

We conducted a retrospective study to investigate the clinical differences between subtypes of rhinitis patients. Our findings were based on a detailed history and nasal examination. The study population was made up of 910 patients who had at least two rhinitis symptoms. These patients were categorized into one of three rhinitis groups: nonallergic rhinitis (NAR), seasonal allergic rhinitis (SAR), and perennial allergic rhinitis (PAR); there were 212 patients (23.3%) in the NAR group, 473 (52.0%) in the SAR group, and 225 (24.7%) in the PAR group. In addition to demographic data, we compiled information on the season when each patient presented, specific symptoms and their triggers, parental history, associated allergic diseases (e.g., skin, lung, and eye allergies), and nasal examination findings. The SAR patients represented the youngest of the three groups. Most SAR patients presented in spring and summer, and this group had the highest incidence of eye itchiness, pharyngeal itchiness, eye redness, and palatal itchiness. In terms of triggering factors, a visit to a green area was significantly more common in the SAR patients, while detergent odor, sudden temperature change, and cold air were significantly more common in the NAR patients. On nasal examination, a pale nasal mucosa was significantly more common in the NAR group. In clinical practice, it is crucial to differentiate between allergic and nonallergic rhinitis. We conclude that relevant information from the history can predict allergic rhinitis. Future studies of prevalence should take into consideration the important findings of our study, including the significance of age and the seasonality of exacerbation of rhinitis symptoms.

RESUMO

BACKGROUND AND GOALS: Growth retardation is one of the most important signs of childhood celiac disease (CD); however, it is not very well known whether craniofacial growth is also affected. We aimed to carry out a detailed craniofacial morphological study to derive a conclusion on the craniofacial features of children with CD. PARTICIPANTS AND METHODS: Eighty-four 2-16-year-old children with biopsy-proven CD and 84 age-matched and sex-matched healthy children were included. Of these, 37 children (44.0%) had been newly diagnosed and 47 (56.0%) were on a gluten-free diet. Anteroposterior and lateral photographs were evaluated using the Scion Image software program for the measurements of the distances between reference points on the face. RESULTS: Except for nasofrontal angle (nfa), nasolabial angle (nla), pronasale height (prnh), nasal dorsum height (ndh), and nasal radix height (nrh), all measurements were significantly greater in patients compared with controls. In celiac children, all facial proportions except forehead/face height (t-gl/t-gn) and nose length/face height (n-ns/t-gn) were significantly different from those of controls. Except for nla, prnh, ndh, nrh, t-gl/t-gn, face height to total face height ratio (sn-gn/t-gn), n-sn/t-gn, ear length to face height ratio (s-sba/t-gn), and face width to face height ratio (z-z/t-gn), all measurements were statistically different in those on a gluten-free diet and newly diagnosed children. CONCLUSION: Most of the facial measurements and proportions of celiac children were different from those of controls. Our data confirm those of a previous study reporting that the forehead proportion is not altered in childhood CD. Pathophysiological mechanisms underlying these alterations are not clear but disruptions of growth during certain critical periods may be responsible.

RESUMO

A 31-year-old male patient with a fatal thrombosis of the internal carotid artery caused by gun shot injury was presented in this case report. The patient was referred to the hospital with a diffuse edema on his left cheek. On otolaryngologic examination, there was a bullet entrance hole at the left mandibular corpus. No exit hole could be found. The finding from his axial computed tomography of neck and paranasal sinuses was normal. On neurological examination, a dense right hemiparesis was observed. In his cerebral angiogram, left common carotid artery was totally obliterated. Diffuse ischemia was observed in the left cerebral hemisphere. Despite intensive interventions, the patient died 4 days after the accident. In the autopsy, a large thrombosis was obtained in the left common carotid artery. This case emphasizes a fatal kinetic energy effect in vascular structures. It is stressed that a gun shot injury could be fatal with its indirect kinetic energy effects at subacute phase.

RESUMO

BACKGROUND: Epistaxis is an important emergency that can sometimes be life threatening without effective intervention. Persistent and recurrent bleeding can lead to aspiration, hypotension, hypoxia, or even severe and mortal cardiovascular complications. Providing prompt hemostasis is important, and the hemostatic method used must be easily and locally applicable, efficient, and inexpensive. OBJECTIVE: The aim of this study was to assess the hemostatic efficacy of Ankaferd Blood Stopper (ABS) in an experimental epistaxis model and to determine the histopathologic alterations with topical ABS application. METHODS: Twenty-eight New Zealand rabbits were evaluated in 4 study groups. Topical ABS, gelatin foam (GF), adrenalin + lidocaine (AL), and serum physiologic as negative control (C) were applied to the animals for controlling epistaxis. The bleeding was generated with a standard mucosal incision in all groups. Cotton pieces soaked with ABS, AL, C, and GF were applied to the nasal bleeding area. Time of hemostasis was recorded. Tissue samples were obtained after hemostasis for histopathologic examination. The samples were stained with hematoxylin and eosin (HE) and phosphotungstic acid hematoxylin (PTAH) and were examined under a light microscope. In this experimental study, the observers were blind to ABS, AL, and C but not to GF, because of its solid nature. RESULTS: Median durations required for hemostasis in ABS, AL, GF, and C groups were recorded as 30, 90, 90, and 210 seconds, respectively. The time until termination of bleeding in the ABS group was significantly shorter than that in the AL, GF, and C groups (P = 0.002, P = 0.002, and P = 0.001, respectively). On histopathologic evaluation, after staining with HE, minimal fibrin at the incision edges and a few extravasated erythrocytes were observed in the C, AL, and GF groups. In the ABS group, a dark amorphous material surrounded by fibrin, filling the space between the edges of incisions, was noticed. Fibrin was determined in the C, GF, and AL groups with PTAH stain and in the positive control group. In the ABS group, it was observed that the amorphous substance surrounded by fibrin seen in the HE sections was not stained with PTAH. CONCLUSIONS: Topical nasal ABS application controlled epistaxis faster than C, GF, and AL in this animal bleeding model. The bleeding model used here might fail to replicate the type of injury that would be likely to result in life-threatening bleeding in humans, which should be considered a limitation of the present study. The histopathologic findings in the nasal incision area suggest that ABS might affect global hemostasis by inducing a unique protein network formation, potentially representing a different mechanism of action among conventional antihemorrhagic applications.

RESUMO

OBJECTIVES: In this study, the effect of local heparinoids on prevention of periorbital edema and ecchymosis due to rhinoplasty was investigated. PATIENTS AND METHODS: Twenty patients (12 males, 8 females, mean age 23.3 years; range 19 to 34 years) who had bilateral osteotomy were randomly administered postoperative local heparinoid on one periorbital region, without performing any care in the other one. One and a half centimeter of heparinoid was applied once a day for nine days. The other periorbital region was used as control group. The heparinoid was applied additionally, 8 mg dexamethasone i.v was administered to all patients 30 minutes before the surgery and 24 hours after the surgery. Photographs of each patient which were taken on postoperative days 1, 3, 5 and 9 were evaluated as double-blind by two observers. Scoring was performed according to edema and ecchymosis scales. RESULTS: There was no statistical difference with respect to edema and ecchymosis between local heparinoid treated and control eyes. CONCLUSION: No hypersensitivity to drugs occurred in any patients. After analysing the scores, we observed that heparanoids administered locally was not effective in preventing periorbital edema and ecchymosis after rhinoplasty (p>0.05).

RESUMO

OBJECTIVES: To investigate the clinical and laboratory outcomes both objectively and subjectively in nasal polyposis patients with or without comorbidity (CoM; asthma and allergy). PATIENTS AND METHODS: Thirty-three nasal polyposis patients (13 women and 20 men) were included into the study. Their mean age was 39.23 +/- 9.13 years. CoM(+) and CoM(-) nasal polyposis patients were compared with each other. Evaluations contained endoscopic nasal examination, acoustic rhinometry, rhinomanometry, visual analog scale score of nasal blockage, olfactory function score, respiratory function test, skin prick tests, and paranasal sinus computed tomography. RESULTS: Recovery was statistically significant in all observed evaluations for endoscopic and radiologic staging, nasal obstruction, and sense of smell compared with the first evaluation in all patients regardless of the subgroups. Although objective measurements of respiratory functions did not show any change, clinical improvement was detected in CoM(+) patients with a decrease of need to their antiasthmatic medical treatment. CONCLUSIONS: Results of CoM(+) patients led to no statistical difference when compared with CoM(-) subgroup. When applying predefined nasal polyposis treatment protocol, the polyp patients with CoMs do not need close follow-up compared to the patients without CoMs.

RESUMO

Osteomas are slow-growing benign tumors of the paranasal sinuses. They originate from the sinus wall and generally fills the sinus cavity. Many osteomas are asymptomatic and diagnosed incidentally on radiographs. The well-circumscribed, dense bony appearance on radiographs is usually diagnostic. Osteomas become symptomatic when they extend to the orbit or cranium. We report a rare case of ethmoido-orbital osteoma. Case reports and a review of the literature concerning osteoma and surgical techniques are presented. Treatment is not recommended in asymptomatic osteomas. If treatment is indicated, external or endoscopic approach can be chosen. The choice of surgical approach depends on the size of the lesion, location, and the experience of the surgeon.

RESUMO

The objective of this study was to evaluate the effect of intranasal estrogen therapy on female vocal quality. Thirty-two women who had surgically induced menopause were included into the study group and examined through hall year for this study. Estrogen treatment was proposed to all of the patients. Twenty-three of them accepted the treatment protocols including oral (n=12) (2mg estradiol; Estrofem; Novo Nordisk, Denmark) and intranasal (n=11) (300 mc g 17beta-estradiol; Aerodiol; Servier, Chambray-les-Tours, France) form of estrogen. The rest of patients refused estrogen treatment and those patients constituted the control group (n=9). Vocal changes were evaluated with Voice Handicap Index (VHI) and acoustic analysis of voice variations (fundamental frequency [F0], SD F0, jitter, shimmer, normalized voice energy, and harmonics-to-noise ratio) at baseline and after 1-year follow-up. According to VHI, while voice improvement was not clear in oral estrogen group, it was significant at intranasal estrogen group. Voice quality in patients treated with hormone replacement therapy (HRT) was significantly higher than patients without HRT. But between two treatment groups, there were no any statistical discrepancy. According to acoustic analysis, vocal stability among the women who use HRT was significantly better than those who did not use. Intranasal estrogen exerted the most significant effects on vocal stability. The data of our study support that voice undergoes changes in lack of estrogen in surgically induced menopausal women. Taken together with the relevant studies, while oral estrogen replacement therapy shows a favorable influence on voice quality, it seems to be more pronounced with intranasal estrogen than oral form.

RESUMO

INTRODUCTION: Conductive hearing loss is affected by physical changes imposed on the mechanical system of the outer or middle ear. Maxillary expansion can affect conductive hearing loss, and the changes have been investigated with pure-tone audiograms. Semirapid and slow methods of maxillary expansion have some advantages over rapid maxillary expansion, but the effects on conductive hearing loss have not been investigated. The purpose of this study was to investigate long-term effects of semirapid maxillary expansion (SRME) with an acrylic bonded appliance on conductive hearing loss by using audiometric and tympanometric records. METHODS: The effects of SRME with a bonded appliance were studied in 19 growing subjects who had narrow maxillary arches and conductive hearing loss. Hearing levels were determined with pure-tone audiometric and tympanometric records. Four records were taken from each subject. The first records were taken before SRME, the second after maxillary expansion (mean, 3.4 months later), the third after retention (mean, 6 months later), and the fourth after fixed-appliance treatment (approximately 2 years later). The data were analyzed with ANOVA. The least-significant difference test was also used to determine when the changes in the measurements were significant. RESULTS: Hearing improved and air-bone gaps decreased at a statistically significant level after active expansion, and these changes remained relatively stable during the last 2 periods. Middle-ear volume increased at a statistically significant level after maxillary expansion and continued to increase until the end of treatment. No significant change was observed in the static compliance value. CONCLUSIONS: SRME treatment has a positive and statistically significant effect on both hearing and normal functioning of the eustachian tubes in patients with transverse maxillary deficiency and conductive hearing loss.

RESUMO

OBJECTIVE: To test the null hypothesis that rapid maxillary expansion (RME) with a rigid bonded appliance has no effect on conductive hearing loss (CHL) in growing children. MATERIALS AND METHODS: Fifteen growing subjects (mean age 13.43 +/- 0.86 years) who had narrow maxillary arches and CHL participated in this study. Three pure-tone audiometric and tympanometric records were taken from each subject. The first records were taken before RME (T1), the second after maxillary expansion (T2) (mean = 0.83 months), and the third after retention (mean = 6 months) and fixed appliance treatment (approximately 2 years) periods (T3). The data were analyzed by means of analysis of variance (ANOVA) and least significant difference (LSD) tests. RESULTS: Hearing levels of the patients were improved and air-bone gaps decreased at a statistically significant level (P < .001) during active expansion (T2-T1) and the retention and fixed appliance treatment (T2-T3) periods. Middle ear volume increased in all observation periods. However, a statistically significant increase was observed only in the T2-T3 period. No significant change was observed in the static compliance value. CONCLUSIONS: The hypothesis is rejected. RME treatment has a positive and statistically significant effect on both improvements in hearing and normal function of the eustachian tube in patients having transverse maxillary deficiency and CHL.

RESUMO

We investigated the incidence and co-existence of hearing impairment and renal abnormalities in healthy children with preauricular tags and pits. Study population consists of 13,740 primary school children from routine health check. Thirty-five children with preauricular tags and pits were noted. Control group consisted of 91 patients without pits and tags, who underwent renal ultrasound and were scheduled to pediatric outpatient clinic. Urinalysis, renal ultrasound, otoacoustic emission were performed in both the groups. The prevalence of renal abnormality (1/36; 2.7%) and hearing impairment (1/36; 2.7%) in patients with preauricular tags and pits was similar to that of control group (3/91; 3.2% and 4/91; 4.3%) (P = 0.87, P = 0.64, respectively). According to our results, it is not necessary to investigate hearing or urinary abnormality in patients with preauricular tag or pit, unless there is an association of a syndrome or family history of hearing or renal impairment.

RESUMO

It has long been known that the major irreversible toxicity of aminoglycosides is ototoxicity. Among them, streptomycin and gentamicin are primarily vestibulotoxic, whereas amikacin, neomycin, dihydrosterptomycin, and kanamicin are primarily cochleotoxic. Cochlear damage can produce permanent hearing loss, and damage to the vestibular apparatus results in dizziness, ataxia, and/or nystagmus. Aminoglycosides appear to generate free radicals within the inner ear, with subsequent permanent damage to sensory cells and neurons, resulting in permanent hearing loss. Two mutations in the mitochondrial 12S ribosomal RNA gene have been previously reported to predispose carriers to aminoglycoside-induced ototoxicity. As aminoglycosides are indispensable agents both in the treatment of infections and Meniere's disease, a great effort has been made to develop strategies to prevent aminoglycoside ototoxicity. Anti-free radical agents, such as salicylate, have been shown to attenuate the ototoxic effects of aminoglycosides. In this paper, incidence, predisposition, mechanism, and prevention of aminoglycoside-induced ototoxicity is discussed in the light of literature data.

RESUMO

Proper selection of anesthetic technique is important in otologic surgical procedures. In the middle ear microsurgery an anesthetic agent must provide bloodless, good surgical field visibility for safe tympanic membrane reconstruction, safe ossicular reconstruction with respect to the basic anatomic structure of the middle ear. Additionally, no alteration of intratympanic pressure is acceptable during the anesthetic act and after its discontinuation. Consequently, postoperative nausea and vomiting should be minimal after tympanoplasty operations for the stability of tympanic graft and ossicles. Therefore, the anesthesiologist must use a technique that provides a sufficiently deep level of anesthesia with minimal intraoperative movement, rapid emergence, good hemodynamic control and tympanometric stability. Currently, many inhaler and intravenous (IV) anesthesia could be preferred for otologic surgical procedures and they offer ideal intraoperative conditions. Dexmedetomidine is a novel analgesic agent that helps this inhaler or IV anesthesia at preoperative state, postoperative period and during surgery especially for hemodynamic stability. In this article, pharmacocinetic properties of dexmedetomidine were described, its advantages for patients undergoing surgery,related patents and its role in otologic surgery were discussed.

RESUMO

Nitric oxide (NO) plays role in a great range of important functions in the organism, such as vasodilatation, relaxation of muscles, neurotransmission, neuromediation, and host defense reactions. In the upper airways, nasal cavities and paranasal sinuses are the main sources of this biological mediator. Although the exact role of NO in nasal physiology remains poorly understood, the functions are thought to be host defense, ciliary motility and improved ventilation-perfusion ratio in the lungs by auto-inhalation. Low NO concentrations were reported in certain diseases such as primary ciliary dyskinesia, cystic fibrosis, and acute and chronic maxillary sinusitis whereas high concentrations were detected in upper airway infection, allergic rhinitis and nasal polyposis. Additionally this ubiquitous radical is being implicated in the regulation of cochlear blood flow, sensorineural hearing loss, middle ear effusions, and outer hair cell and vestibular functions. Solid tumors is another area where NO appears to have both tumor-promoting and tumor-inhibiting effects. The presence of NO with high levels within the nose and paranasal sinuses makes it reasonable to believe that this pluripotent gas is involved in a variety of physiological as well as pathophysiological events in the airways. Although NO has an ever-increasing role in various areas related to the practice of otolaryngology, further research is required to understand fully the role of NO in the upper airways.

RESUMO

It is known that cigarette smoke induces cytological alterations on the respiratory and olfactory mucosa of the nasal cavity. We evaluated whether cigarette smoking had adverse effects on the epithelium of the vestibule, in the absence of any published ultrasutructural studies. We evaluated ten patients suffering from septum deviation, eight of whom were long-term smokers. While each layer of the epithelium obtained from the non-smokers consisted of a homogeneous cell population, each from the long-term smokers consisted of a heterogeneous cell population. The most prominent changes occurred in the shape and size of the cells and nuclei, the number and length of the cytoplasmic projections, the number and distribution pattern of the desmosomes, and the width of the intercellular spaces. We concluded that cigarette smoke produces hyperplastic and dysplastic changes, important factors related with cancer development, on the epithelium of the vestibule.

RESUMO

Experimental acute sinusitis was induced in 21 New Zealand hybrid rabbits by occluding the ostium and inoculating them with Streptococcus pneumonia. While a group of rabbits with sinusitis was left untreated, two other groups were administered parenteral sodium nitroprussid (SNP) and oral levofloxacin for ten days. While staphylococci species, non-hemolytic streptococcus and contaminated flora were isolated from the sinuses of controls, Streptococcus pneumonia was re-isolated in two of six untreated rabbits, in one of six SNP administered rabbits and none of the levofloxacin treated rabbits. Serum and maxillary sinus mucosal nitric oxide (NO) levels were correlated. While the mean maxillary sinus NO level of controls was significantly higher than that of untreated rabbits, the mean maxillary sinus and serum NO levels were significantly higher in SNP administered rabbits than in the others. Although goblet cell hyperplasia and squamous cell metaplasia were detected in some slides, edema and neutrophil infiltration were the prominent findings. The most severe inflammatory changes were found in the untreated sinusitis group on the third and fifth days. The earliest improvement was observed in the levofloxacin treated rabbits.
