Successful localization of abnormal parathyroid tissue with ultrasound-guided methylene blue dye injection before surgery for metastatic or recurrent thyroid cancers and parathyroid adenomas.

OBJECTIVES: A surgery to be performed on a previously operated neck includes difficulties such as increased risk of complications and prolonged operation time. The aim of the present study is to analyze the benefit of pre-anesthetic ultrasound-guided injection of methylene blue into parathyroid adenomas and abnormal lymph nodes to simplify their safe and satisfactory extraction. METHODS: We analyzed the case series records of 14 patients who were operated for reoperative neck surgery due to recurrent thyroid cancer (8 patients) and parathyroid adenoma (6 patients) and in the technique; 0.2 ml of a 1:5 dilution of 1 % methylene blue solution was injected directly onto the target during real-time ultrasound guidance before the operating room. RESULTS: In adenomas, ultrasound-guided methylene blue injection was successfully applied in all cases, an average of 33.1 min before entering the operating room (range = 28-38 min). There were no complications related to dye injection. For patients with recurrent thyroid tumors, preoperative ultrasound-guided methylene blue injection was successfully applied in all patients, on average 27.5 min before entering the operating room (range = 20-35 min). No complications occurred due to dye injection. The blue stained lesion was easily identified during surgery. CONCLUSIONS: We analyzed the feasibility of the injection process, the certainty of defining pathological lymph nodes, and the complications of the procedure. Preoperative administration of methylene blue preserved its intraoperative efficacy and maintained the easy the detection of reoperative or primary pathologies. The present study suggest that methylene blue dye injection is a safe, sufficient, and quietly effective method for identifying recurrent tumors and parathyroid adenomas in scarred reoperative neck surgeries. Our cases had comparatively short operative times and lower complication rates.

A Rare Cause of Respiratory Distress in Newborn: Huge Nasal Chondromesenchymal Hamartoma; Patient Report.

ABSTRACT: Nasal chondromesenchymal hamartoma is a rare benign tumor of the sinonasal tract in pediatrics and only few cases in infantile, early pediatric, and adolescent population have been reported. Nasal chondromesenchymal hamartoma commonly presents as respiratory difficulty, intranasal mass, or facial swelling and typically arises from the nasal septum or vestibule, lest frequently maxillary or ethmoid sinuses, orbit, nasopharynx, and oropharynx. The authors report a case of nasal chondromesench- ymal hamartoma that caused respiratory distress since birth, in a 4- week-old (28 days) infant which was arised from the medial aspect of the middle turbinate, an unexpected localization.

Can isolated sudden sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) be symptoms of COVID-19?

OBJECTIVES: The symptoms of COVID-19 at the time of presentation mainly include fever, cough, respiratory distress and myalgia. On the other hand, as neurological symptoms, disruption of taste and smell and cerebrovascular pathologies are well-known, whereas other neurological symptoms and signs are being newly recognized. Sudden-onset sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) are otologic emergencies that are frequently encountered by otorhinolaryngology specialists. Although there are many articles describing SSNHL and Bell's palsy in the literature, the literature describing their relationship to COVID-19 is limited. In our study, we aimed to present the neuro-otologic relationship of SSNHL and Bell's palsy with COVID-19. MATERIAL AND METHODS: The pretreatment real-time oronasopharyngeal PCR tests, COVID-19 symptomatology and COVID-19 infection statuses of patients who presented to our clinic with isolated SSNHL and Bell's palsy between April 2020 and April 2021 were questioned, and the data of the patients were collected. Throughout their treatment, the patients were followed-up in terms of COVID-19 infection. This is a prospective study. Moreover, to observe the change in the incidence, the data of patients visiting between January 2019 and January 2020 were also collected. The data of the patients were statistically analyzed using SPSS. RESULTS: The study included a total of 177 patients. The SSNHL group consisted of 91 patients, and the Bell's palsy group consisted of 86 patients. Neither group showed a statistically significant difference in comparison to the year without the pandemic in terms of the patient numbers (incidence), sex, age, morbidity, response to treatment or social habits. There was a statistically significant difference in age only in the Bell's palsy group, but this difference was not medically significant. CONCLUSION: As a result of our study, we did not observe a relationship between COVID-19 and cases of SSNHL and Bell's palsy. It is recommended to apply standard otologic treatment to isolated SSNHL and Bell's palsy patients whose association with COVID-19 is not determined.

The Complication of Tension Pneumocephalus After Septoplasty.

ABSTRACT: This paper presents a case of tension pneumocephalus with severe headache 2 days after septoplasty surgery. In such cases, endoscopic sinus surgery (ESS) or open approach can be used for repair of the defect. However, pneumocephalus, especially caused by minor defects, improves spontaneously with conservative treatment. In our case, the pneumocephalus was responsive to conservative treatment with bed rest, head elevation. His examinations in the 3rd and 8th months after discharge were uneventful and CT scan revealed no signs of pneumocephalus. In severe headaches developing after septoplasty, the possibility of intracranial complications should be evaluated. Simple conservative treatment should be tried before surgery, but then the patient should be examined at regular intervals.

An Extraordinary Complication of Chronic Tonsillitis: Perforation of Posterior Plica.

ABSTRACT: Tonsillitis is a very common condition. It is usually of viral origin, is self-limiting, is generally treated conservatively in practice. Complications can be divided into non-suppurative and suppurative. According to the literature search, there is no reported case of posterior plica perforation caused by recurrent tonsil infections. The authors aimed to present the first case of posterior plica perforation caused by recurrent tonsillitis in the literature.

The effects of acute hypoxia on audition: An experimental study.

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) is a health problem that has increasing importance in society. In the literature, many studies about an audition in patients with OSAS are present. In this study, the effects of hypoxia on an audition that develop during the apnea attacks in OSAS were investigated experimentally. METHODS: This study was conducted in Inonu University Audiology Laboratory after the approval of Inonu University Faculty of Medicine Experimental Animal Research Ethics Committee (Protocol Number: 2011/A-102). In this study, 15 Wistar albino rats with a weight of 250-300 g were used. Anesthesia was performed by 40 mg/kg Ketamine and 5 mg/kg Xylazine through intramuscular administration. The processes were applied in the silence. This study involved 15 rats with normal auditory functions. Only tracheotomy was performed in the control group. Auditory assays were administered with otoacoustic emission (DP gram) before and after the process. In hypoxia group, hypoxia was created by making apnea attacks that lasted at least 10 seconds after the tracheotomy process. Auditory assays using DP gram were performed before tracheotomy and during hypoxia in the hypoxia group. RESULTS: In the control group, statistically significant values were not found. In the hypoxia group, statistically significant differences were detected in high frequencies. CONCLUSION: In conclusion, cochlear reply decreased in high frequencies during hypoxia that was created by apnea attacks.

A Rare Cause of Headache That Should Be Kept in Mind: Isolated Concha Bullosa Fungus Ball.

Concha bullosa is characterized by pneumotization of the middle turbinate and is a common variation of sinonasal anatomy and is often asymptomatic. The presence of a fungus ball in concha bullosa and the associated clinic symptoms are very rare. Concha bullosa fungus balls are a rare differential diagnosis in a patient presenting to the otorhinolaryngology outpatient clinic with headache.In this article, the authors aimed to present an isolated fungus ball case in concha bullosa as a rare cause of headache differential diagnosis.

Endovascular Treatment of Carotid Pseudoaneurysm Bleeding Due to Parapharyngeal Abscess.

Carotid artery pseudoaneurysm are a rare complication of deep neck infections, especially in the antibiotic era. Although it is rare, it may result in life-threatening conditions. Here, the authors present a case of pseudoaneurysm of the carotid artery caused by parapharyngeal abscess and causing massive oropharyngeal bleeding and treat with endovascular approach in a 40-year-old woman presenting with neck swelling and fever.

The effect of lycopene on the ototoxicity induced by cisplatin.

UNLABELLED: Background/aim: To determine the efficacy of lycopene, which is considered an antioxidant agent, in decreasing the cochlear damage induced by cisplatin. MATERIALS AND METHODS: A total of 38 rats were randomized into 4 groups: control, cisplatin, cisplatin + lycopene, and lycopene-treated groups. In all groups, the distortion-product otoacoustic emission measurements were performed on days 0, 1, 2, and 5. RESULTS: There were no significant differences between the control and lycopene groups at any frequencies. In the cisplatin group, the statistically significant differences were found in the measurements taken between day 0 and day 5 at all frequencies and between days 1 and 5 and days 2 and 5 at some frequencies (P < 0.05). In the cisplatin + lycopene group, a statistically significant difference was found at some frequencies between the measurements taken on days 0 and 5, days 1 and 5, and days 2 and 5 (P < 0.05). Contrary to the results found in the cisplatin group, hearing ability in the lycopene-treated group was observed as being preserved at low frequencies in the measurements taken on days 0 and 5 and days 2 and 5. CONCLUSION: The data of this study suggest that lycopene can prevent the development of ototoxicity induced by cisplatin, especially at low frequencies. Studies on this issue with longer durations and different dose ranges may contribute to the identification of potentially prophylactic effects of lycopene against cisplatin ototoxicity at higher frequencies, as well.
