Rhinitis medicomentosa and substance addiction.

BACKGROUND: Rhinitis medicomentosa (RM) is a form of non-allergic rhinitis caused by the use of nasal decongestants for longer than the recommended duration. Because of this problem of use, addiction to the drug occurs in individuals. In our study, we aimed to evaluate the susceptibility of RM patients to substance addiction. METHODS: The study was planned as a prospective, multicentric study between September 2022 and September 2023. Patients diagnosed with RM were included in the study. Beck depression scale, Drug use disorders identification test, Substance Abuse Proclivity Scale were applied to the patients participating in the study. The research data were analyzed electronically with SPSS program version 25. RESULTS: The study included 86 patients with an average age of 31 years. The average duration of medication use was 22 months. Age, gender, duration of nasal congestion, duration of drug use and smoking were not independent predictors for depression and substance use tendency. CONCLUSION: The relationship between RM and addictive substances is not clear. The tendency to use drugs did not increase in RM patients. In the light of these data, we think that there is no need for a practice other than routine functioning in the use of drugs and similar substances that are likely to cause addiction in RM patients.

Comparison of effects of dexmedetomidine and amifostine against X-ray radiation-induced parotid damage.

Radiotherapy can be employed as a therapeutic modality alone in the early stages of cancer and is used together with other treatments such as surgery and chemotherapy in more advanced stages. However, exposure to ionizing radiation in association with radiotherapy affects several organs in the head and neck and can give rise to early and late side effects. Exposure to ionizing radiation used in radiotherapy is known to cause cell damage by leading to oxygen stress through the production of free oxygen radicals (such as superoxide radicals, hydroxyl radical, hydrogen peroxide, and singlet oxygen), depending on the total radiation dosage, the fractionation rate, radiosensitivity, and linear energy transfer. The purpose of the present study was to determine the potential protective role of a powerful and highly selective α2-adrenoreceptor agonist with a broad pharmacological spectrum against salivary gland damage induced by ionizing radiation exposure. Forty Sprague-Dawley rats were divided into five groups-control, ionizing radiation, ionizing radiation + dexmedetomidine (100 µg/kg), ionizing radiation + dexmedetomidine (200 µg/kg), and ionizing radiation + amifostine (200 mg/kg). Following exposure to ionizing radiation, we observed necrosis, fibrosis, and vascular congestions in parotid gland epithelial cells. We also observed increases in malondialdehyde (MDA) and cleaved Caspase-3 levels and a decrease in glutathione (GSH). In groups receiving dexmedetomidine, we observed necrotic epithelial cells, fibrosis and vascular congestion in parotid gland tissue, a decrease in MDA levels, and an increase in GSH. Dexmedetomidine may be a promising antioxidant agent for the prevention of oxidative damage following radiation exposure.

Dynamic thiol/disulphide balance in patients undergoing hypotensive anesthesia in elective septoplasties.

OBJECTIVE: We aimed to investigate the effects of hypotensive anaesthesia on oxidative stress with serum thiol/disulphide balance in patients undergoing elective septoplasty procedures under general anaesthesia. METHODS: Seventy-two patients between the ages of 18-60, with a physical condition I -II, according to the American Society of Anesthesiologists, were included in this prospective observational study. Septoplasty was chosen for standard surgical stress. According to the maintenance of anaesthesia, patients were divided into the groups as Hypotensive Anaesthesia (n = 40) and Normotensive Anaesthesia (n = 32). Serum thiol/disulphide levels were measured by the method developed by Erel & Neselioglu. RESULTS: The native thiol and total thiol values of both groups measured at the 60th min intraoperatively were significantly lower than the preoperative values (both P < .01). Intraoperatively, at the 60th min, there was no significant difference in terms of post-native thiol and post-total thiol levels between hypotensive and normotensive anaesthesia groups (P = .68 and .81, respectively). Age >40 years and female gender were found to have a significant effect on dynamic oxidative stress (P = .002 and .001, respectively). CONCLUSION: This pilot study has found that hypotensive anaesthesia had no adverse effect on dynamic thiol/disulphide balance in elective surgeries.

Sociodemographic Characteristics Associated With Speech and Language Delay and Disorders.

The aim of this study was to identify major risk factors and sociodemographic characteristics responsible for speech and language delay/disorders. Two hundred twenty-eight children (aged 24-72 months) with speech and language delay/disorders participated in this study. The Ankara Developmental Screening Inventory and The Peabody Picture Vocabulary Test were used to assess language profiles and developmental stages of children. Low income, nonattendance in preschool education, low maternal education, having two or more siblings, later birth order (order of siblings), family history of speech and language delay/disorders, preterm birth, low birth weight, and birth complications or the need for intensive care support during neonatal period were identified as risk factors (all p < 0.005). Both sociodemographic and biologic factors were associated with speech and language delay/disorders. Awareness of these factors may provide a chance for earlier diagnosis and intervention. Identification of risk factors of these children would contribute to our knowledge in this field.

The evaluation of prognostic factors in endoscopic cartilage tympanoplasty.

PURPOSE: The aim of the present study was to evaluate the prognostic factors that may affect the success in endoscopic cartilage tympanoplasty and determine the outcomes of endoscopic cartilage tympanoplasty. METHODS: This study included 312 patients who underwent transcanal endoscopic type I cartilage tympanoplasty. The effects of sex, the affected side, the size of the perforation, the location of the perforation, the absence of myringosclerosis, external ear canal protrusion, the condition of the contralateral ear, and surgical experience on the rate of graft success and hearing improvement were investigated. RESULTS: The affected side, sex, location of the perforation, myringosclerosis, the condition of contralateral ear, and surgical experience did not significantly affect the surgical success (p > 0.05). However, the size of perforation and ear canal wall protrusion were significantly related to both functional and anatomical success (p < 0.05). CONCLUSION: Endoscopic transcanal type I cartilage tympanoplasty can be performed with a high anatomical and functional success rate. However, surgeons should be more careful and design a case-specific operation strategy in patients with external ear canal anterior wall protrusion and large perforations.

The therapeutic effect of thymoquinone on acoustic trauma-induced hearing loss in rats.

Thymoquinone has antioxidant properties. We hypothesized that thymoquinone may prevent or alleviate hearing loss induced by acoustic trauma. We aimed to study thymoquinone's effect on hearing function with distortion-product otoacoustic emissions and auditory brainstem response. Thirty adult Spraque Dawley rats were randomized into four groups following exposure to acoustic trauma for 4 h. Control group (n = 7) did not receive further treatment. Thymoquinone-20 (n = 8) and Thymoquinone-40 (n = 8) received 20 and 40 mg/kg of intraperitoneal thymoquinone, respectively. Corn-oil group (n = 7) received 1 ml of corn oil intraperitoneally. Hearing function of both ears was tested with distortion-product otoacoustic emission and auditory brainstem response before, and shortly after acoustic trauma, and 96 h following acoustic trauma. Post-trauma signal/noise ratios and wave V amplitude/latencies of all groups were significantly low compared with pre-trauma values, which indicate no preventive effect of thymoquinone. Rats in Thymoquinone-20 showed a significantly improved distortion-product otoacoustic emission and auditory brainstem response results at 4000 frequency and above in post-treatment tests (p < 0.05). Improvement in Thymoquinone-40 at the same frequencies was insignificantly inferior to Thymoquinone-20, yet superior to control and corn-oil groups (p < 0.05). We conclude that thymoquinone may not prevent acoustic trauma-induced hearing loss, however, at 20 mg/kg for 96 h, may repair the damage.

Acute airway compromise due to ruptured inferior thyroid artery aneurysm.

A cervical hematoma secondary to the spontaneous rupture of an aneurysm is an uncommon but catastrophic life-threatening condition because it can potentially obstruct the airway. Inferior thyroid artery aneurysm and rupture is a very rare clinical entity and only a limited number of cases have been reported in the literature. In this article, we present the case of a female patient who suffered from a rapidly enlarging cervical mass followed by a rapid onset of dyspnea as a result of rupture of an inferior thyroid artery aneurysm. The diagnosis was confirmed by magnetic resonance angiography, and delayed surgery resulted in an uneventful outcome. We aim to draw the attention of emergency physicians to this rare condition.

The Effects of Curcumin on Wound Healing in a Rat Model of Nasal Mucosal Trauma.

We explored the effects of topical curcumin on the healing of nasal mucosal wounds. A total of 32 Sprague-Dawley Albino rats were randomized in equal numbers into four groups, and unilateral nasal wounds were created using an interdental brush. Group 1 (the sham-control group) contained untreated rats with traumatized right-side nasal cavities; Group 2 and 3 rats were similarly traumatized and treated with topical curcumin (5 and 10 mg/mL) dissolved in dimethyl sulfoxide daily for 7 days after trauma; Group 4 rats were treated with topical dimethyl sulfoxide only. All rats were decapitated on day 15 and the healing sites evaluated by blinded observers in terms of the presence of cellular hyperplasia, goblet cell hypertrophy and degeneration, leucocytic infiltration, ciliary loss and degeneration, edema, and vascular dilation. On histopathological evaluation, all of cellular hyperplasia, leukocytic infiltration, and edema were significantly reduced in Group 3 compared with Group 1 (p = 0.001, p = 0.004, and p = 0.008, resp.). Thus, curcumin reduced the inflammatory response and significantly accelerated wound healing.

Is there a relationship between myeloperoxidase activity and conductive hearing loss in chronic otitis media complicated by cholesteatoma?

We conducted a prospective, controlled study of patients with chronic otitis media and cholesteatoma (1) to examine the expression of myeloperoxidase (MPO) using immunohistochemical staining techniques and (2) to investigate the relationship between MPO activity and the degree of conductive hearing loss in these patients. Our study population included 51 adults-26 men and 25 women, aged 18 to 58 years (mean: 37.5)-who had been diagnosed with chronic otitis media and cholesteatoma by physical examination and computed tomography (study group). Another 30 patients-13 men and 17 women, aged 18 to 52 years (mean: 32.7)-who had chronic otitis media without cholesteatoma served as the control group. Following audiometric evaluations, all patients underwent appropriate surgery. Postoperatively, cholesteatoma samples were analyzed by immunostaining for MPO positivity as a marker for acute inflammation. We found that MPO activity was present in all 51 study patients (100%) but in only 10 controls (33.3%); the difference was statistically significant (p< 0.01). In the study group, the degree of MPO activity was slight in 6 patients (11.8%), moderate in 24 patients (47.1%), and intense in 21 patients (41.2%), while in the control group, all 10 MPO-positive cases showed only a slight degree of activity. We also found a statistically significant association in the study group between the degree of MPO activity and the degree of conductive hearing loss (χ(2) = 13.518; p < 0.001). We encourage further study of all steps in the process of cholesteatoma formation.

Comparison of Tone Burst, Click and Chirp Stimulation in Vestibular Evoked Myogenic Potential Testing in Healthy People.

OBJECTIVE: Vestibular evoked myogenic potential (VEMP) is a clinical test used in the diagnosis of vestibular diseases. VEMP uses several stimulants to stimulate the vestibular system and measure myogenic potentials. The aim of this study was to compare the effects of tone burst, click, and chirp stimulation in VEMP on the latency and amplitude of myogenic potentials. MATERIALS AND METHODS: We compared the results of 78 ears from 39 volunteers. We measured the sternocleidomastoid muscle potential of each ear following a 500-Hz tone burst, click, and chirp stimulation while in a sitting position and evaluated the latency and amplitude. RESULTS: The tone burst stimulus resulted in waves with longer latency (15.8±1.9 ms) but higher amplitude (35.9±17.1 µV) compared with the other stimuli, and the chirp stimulus resulted in waves with shorter latency (9.9±2.4 ms) but lower amplitude (33±18.6 µV) (p<0.001). The VEMP asymmetry ratio did not significantly differ. ONCLUSION: Because the amplitudes and latencies of different stimuli significantly differ, further studies including more patients and stimulus types are needed to obtain standardized VEMP protocols.

Could cellular proliferation be a predictive index for the relapse of nasal polyposis and down-regulated by nasal steroid treatment?

The aim of this article is to identify the cellular mitotic activity using Ki-67 monoclonal antibody for predicting relapses of nasal polyposis after surgery. A prospective study was conducted at Kartal Training and Research Hospital Otolaryngology Department between January 2006 and September 2008. Nasal polyps were obtained from all patients and pathological materials were analyzed for the Ki-67 staining using immunohistochemistry. Patients were followed after surgery for 12 months for relapse. There was no statistically significant difference between recurrent and nonrecurrent polyps. Polyp recurrence has a multifactorial origin. Ki-67 index alone does not provide sufficient information about polyp recurrence before the operation.

Skin prick test reactivity in patients with chronic eczematous external otitis.

OBJECTIVES: To investigate the incidence of skin prick test (SPT) positivity in patients with eczematous external otitis. METHODS: Forty-six patients with eczematous external otitis and forty-four healthy volunteers were included in the study. All the patients were skin-tested by prick test. Reactions were assessed by the degree of redness and swelling and the size of the wheal produced. RESULTS: According to SPT positivity and total immunoglobulin E values, the difference between the study and the control groups was statistically significant (P<0.05). The most common skin reactions were against to mites and grasses in this study. CONCLUSION: Eczematous external otitis is perhaps the most difficult to treat of all forms of external otitis because the provocative agents usually remain undiagnosed. Patients suffering from eczematous external otitis symptoms should be investigated for allergens and be informed for prevention of the causative agents. SPT might be performed in cases of prolonged or treatment-resistant external otitis.
