ABSTRACT

OBJECTIVE: This study aimed to compare daily and total recreational music exposure levels and extended-spectrum audiogram results in young adults without pre-existing hearing problems. DESIGN: The study included healthy volunteers aged 18-25 with no known ear disease or hearing loss. Participants completed a questionnaire, underwent otoscopic and tympanometric examinations, and determined preferred music volumes in an audiometry booth using calibrated music samples of their preferred genres. Hearing thresholds up to 16 kiloHertz (kHz) were measured. Daily music exposure for each participant was normalized to 8 h to calculate a time-weighted average of 8 h (TWA8). Total exposure (TE) was calculated by multiplying TWA8 by the number of years of music listening. RESULTS: A total of 32.4% of participants had TWA8s above 65 dB. Their hearing thresholds at 125, 250, 500, and 16,000 Hz and the average of 125 Hz-8 kHz were significantly higher. Participants with TWA8s above 65 dB were also more prone to speaking loudly and experiencing communication difficulties on the phone. Those with a TE of more than 400 experienced significantly more speech discrimination difficulty in noisy environments and temporary hearing loss/tinnitus after exposure to loud music. Participants with a TE above 700 had worse thresholds at 4, 14, and 16 kHz frequencies, as well as 125-8000 Hz and 500-4000 Hz averages compared to those with a TE below 700. CONCLUSIONS: This study provides evidence that recreational music with much lower exposure levels than the universally accepted TWA8 of 85 dB could negatively impact hearing in healthy young adults. Therefore, maintaining a maximum TWA8 of 65 dB is recommended.

ABSTRACT

OBJECTIVE: Horseshoe kidney is the most common renal fusion anomaly, accounting for 90%. The study aims to explore the variations in the renal arteries of individuals with horseshoe kidney anomalies and contribute to the classification in the literature. MATERIALS AND METHODS: Computed tomography images of 145 individuals who had intravenous contrast-enhanced abdominal computed tomography for any reason and had horseshoe kidney anomalies were analyzed retrospectively, and the presence, origin, and number of accessory renal arteries were evaluated. Then, classification was performed according to the origin of the accessory arteries. RESULTS: In 145 individuals, 44 different combinations of the accessory artery according to the origin and number were obtained. Most common accessory artery combination was type 2a (M1). According to our classification, 13.1% of the patients were type 1, 57.2% were type 2, 17.2% were type 3, 10.3% were type 4, and 1.4% were type 5. CONCLUSION: The classifications of arterial variations in horseshoe kidney anomalies did not match each other in previous studies and did not comprise all patients because they were conducted with a small number of cases. A more comprehensive new classification was created in our study according to accessory artery origins with the help of previous studies.

ABSTRACT

OBJECTIVE: Malignant bladder neoplasms can cause life-threatening persistent hematuria. Selective transarterial embolization is an effective way to achieve hemostasis in such patients. The purpose of our study is to share our experience in these patients and to evaluate the short- and long-term effectiveness of this procedure. METHODS: Twelve male patients with intractable hematuria due to bladder carcinoma were included in the study. A total of 17 selective transarterial embolization procedures (bilateral in 5 patients) were performed in 12 patients with microspherical particles and microcoils. RESULTS: Complete control of bleeding was achieved in 9 patients after the procedures whereas the need for transfusion continued in 3 patients. Approximately 75% bleeding control was achieved during our average 6-month (4- to 12-month) follow-up period. After the procedure, the patients had mild complaints that lasted for a few days, such as pain (66%), fever (42%), and nausea (50%). No major complications occurred. CONCLUSION: Selective transarterial internal iliac artery embolization is a reliable method that can be used for the palliative treatment of intractable hematuria due to bladder carcinomas.

ABSTRACT

BACKGROUND: In recent years, many studies have proven that percutaneous thermal ablation is an effective second-line treatment method with low complication rates in early-stage non-small cell lung carcinoma and lung metastases. Radiofrequency ablation and microwave ablation are commonly used for this purpose. PURPOSE: To evaluate the factors affecting the success of the percutaneous thermal ablation treatment with technical success, complication rates, and long-term follow-up results in metastatic lung lesions. MATERIAL AND METHODS: Computed tomography (CT)-guided percutaneous ablation was performed for 70 metastatic lung lesions in 35 patients (22 men, 13 women; mean age = 61.34 years; age range = 41-75 years). Radiofrequency ablation was performed in 53/70 (75.7%) lesions and microwave ablation in 17/70 (24.3%) lesions. RESULTS: The technical success rate was 98.6%. Median overall survival, progression-free survival, and local recurrence-free survival of the patients were 33.9 months (range=25.6-42.1 months), 12 months (range=4.9-19.2 months), and 24.2 months (range=8.2-40.1 months), respectively. One- and two-year overall survival rates were 84% and 74%, respectively. Median progression-free survival times were 20.3 months and 11.4 months, respectively, according to the number of metastatic lung lesions being single and multiple, and the difference was statistically significant (P = 0.046). According to the number of lesions ≤3 and >3, the difference was also found statistically significant (P = 0.024) (14.3 months and 5.7 months, respectively). CONCLUSION: In conclusion, CT-guided percutaneous thermal ablation is a safe and effective treatment method in metastatic lung lesions. The number of lesions is the most important factor in predicting treatment success.

ABSTRACT

PURPOSE: To evaluate the expansion effect of self-expandable stents during the first week after carotid artery stenting (CAS) procedure and to examine the variation of the effect according to the carotid plaque type. METHODS: Seventy stenotic carotid arteries of 69 patients were stented by using self-expanding Wallstents with diameters of 7 and 9 mm, after detection of stenosis and plaque type by Doppler ultrasonography. Post-stent aggressive ballooning was avoided and residual stenosis rates were measured with digital subtraction angiography. After the stenting procedure, the caudal, narrowest, and cranial diameters of stents were measured with ultrasonography at 30 min, first day and first week. Stent diameter increase and change according to plaque type were evaluated. Two-way repeated measure ANOVA test was used for statistical analysis. RESULTS: A significant increase was observed in the mean stent diameter in the three stent regions (caudal, narrow, and cranial) from the 30th minute to the first and seventh days (p < 0.001). The most prominent stent expansion occurred in the cranial and narrow segments within the first day. In the narrow stent region; Stent diameter increase between 30th minute-first day, 30th minute-first week, and first day-first week were all significant (p < 0.001). At 30 min, first day, and first week, no significant difference was detected between plaque type and stent expansion in caudal, narrow, and cranial regions (p = 0.286). CONCLUSION: We think that keeping the lumen patency limited to 30% residual stenosis after CAS procedure by applying minimal post-stenting balloon dilatation and leaving the remaining lumen expansion to the self-expanding feature of the Wallstent might be a sensible approach in order to avoid embolic events and excessive carotid sinus reactions (CSR).

ABSTRACT

PURPOSE: We aimed to correlate the presence or absence of embolic debris in filter-type embolic protection devices (EPD), which are frequently used during carotid artery stenting (CAS), with possible risk factors and ultrasonographic plaque features. MATERIALS AND METHODS: Eighty patients, who underwent CAS using a filter-type EPD in the period between July 2016 and March 2019, were included in our study. The modified Gray-Weale classification (mGWC) subtypes obtained in the pre-procedural ultrasonographic examinations were recorded. In addition, other patient-related risk factors considered to be related to a distal embolism were recorded. After the procedure the filters were evaluated to detect and examine embolic debris in the pathology clinic. The presence and features of embolic debris in the filters were recorded. RESULTS: In the examinations performed after CAS, embolic debris was macroscopically and microscopically detected in 22 (27%) and 34 (42.5%) of the filter-type EPDs, respectively. A significant correlation was found between the change in the mGWC category of stenotic plaques from type 5 to type 1 and the presence of embolic debris in the filter (p < 0.05). Furthermore, a significant relationship was found between stenotic segment length and the presence of embolic debris in the filter (p < 0.05). The presence of embolic debris was not statistically significantly related to predisposing risk factors for atherosclerosis (p > 0.05). CONCLUSIONS: During CAS, the likelihood of the presence of embolic debris in the EPDs increases as mGWC categories change from type 5 to type 1 and as the length of the stenotic segment increases.

ABSTRACT

PURPOSE: In this study, we proposed a "sliced-partial thickness cartilage graft" for nasal contour restoration purposes and compared the long-term graft survival and histological changes of sliced, crushed, and intact cartilage grafts. METHODS: Nasal septal and auricular cartilage grafts were harvested from 8 rabbits. Sliced, crushed, or intact cartilage grafts were measured in thickness with a micrometer and re-implanted. 4 months later, specimens were histologically evaluated and thickness were measured. RESULTS: Both nasal septal and auricular crushed cartilage lost significantly more chondrocytes than sliced samples together with fibrosis, multiple fracture lines, and even ossification. Sliced and intact cartilages were histologically similar except sliced cartilage had some minor changes limited to its cut surface. Sliced cartilages retained their thickness, histology, and structural properties in the long term similar to intact cartilages whereas -contrary to expectations- crushed specimens had significantly higher thickness measurements at the end of 4 months. CONCLUSION: Sliced cartilage grafts prepared with an atraumatic cartilage slicer are an ideal camouflaging material with its uniform thickness, and malleability. Crushed cartilages seemingly getting thicker without histological findings could be explained by lower than actual initial measurements due to its structural weakness and getting squeezed when the standard pressure of the micrometer was applied.

ABSTRACT

INTRODUCTION AND AIMS: Serebral silent ischemia is a complication of carotid stenting. If silent ischemia occurs 24 h later of carotid stenting, it called early serebral silent ischemia. The aim of this study was to evaluate the effect of heparin infusion on the prevention of early silent ischemia in patients who underwent carotid stenting. MATERIALS AND METHODS: We included 26 patients who underwent carotid stenting. Patients who had carotid stenting, we randomized into two groups. The first group of patients were given continuously heparin infusion a maximum of 20,000 units for 24 h, and screened the aPTT value each 6 h. The aPTT value aimed a range of 2-3 times to up baseline. The second group didn't take heparin infusion. Diffusion weighted magnetic resonance imaging (DWI-MRI) and gradient echo (GRE) sequences performed in all patients at the 24 h of carotid stenting. RESULTS: Early serebral silent ischemia was detected by DWI-MRI in 13 (50%) of 26 patients who underwent carotid stenting. Seven (53.80%) of 13 patients whit early serebral silent ischemia did not receive heparin treatment, while 6 (46.20%) received heparin treatment. There was no symptomatic or asymptomatic acute hemorrhage in patients who treated with heparin. CONCLUSION: In our study, the continuation of anticoagulant therapy for 24 h to prevent early silent ischemia was not statistically significant. Also there is no reduction for count of serebral silent ischemia between two groups. However, due to the small number of patients in the study, future studies are required with more patients.

ABSTRACT

PURPOSE: The aim of our study was to evaluate the availability of magnetic resonance spectroscopy (MRS) for the differentiation of benign or malignant pulmonary nodules and masses. METHODS: A total of 59 patients (45 male, 14 female) with pulmonary nodules and masses were included in this prospective study. MRS was applied to the pulmonary lesions of the patients and choline levels were determined. Afterwards CT-guided percutaneous needle biopsy was performed. According to the biopsy results, pulmonary lesions were benign in 25 patients and malignant in 34 patients. RESULTS: Choline levels were significantly higher in malignant lesions compared with benign lesions (p < 0.001). When the other conditions were kept constant, the probability of malignancy significantly increased by 17.38-fold (95% CI, 3.78-79.93) in those with choline levels >1.65 µmol/g compared to those with choline levels ≤1.65 µmol/g (p < 0.001). CONCLUSION: MRS is a noninvasive method that can be used in the differential diagnosis of pulmonary nodules and masses.

ABSTRACT

INTRODUCTION: Thyroid ultrasonography (US) is the first-step noninvasive and easily accessible diagnostic method widely used in the detection and characterization of nodular thyroid disease. We aimed to develop a TI-RADS, which is easy to apply and only relies on the counting of suspicious criteria. In order to measure the reliability of the system, we investigated its correlation with fine needle aspiration biopsy (FNAB) and post-surgery histological results. MATERIALS AND METHODS: In this prospective study, 242 patients who had undergone FNAB with simultaneous cytopathologist in the radiology department between April and August 2016 were analyzed. Before FNAB, the thyroid gland was re-evaluated with US, and TI-RADS classification was made. Demographic characteristics, family thyroid cancer history and radiotherapy history to the neck region were noted. RESULTS: Of the 242 patients, 17.3% were male (42 males/200 females). US-guided FNAB was applied to all patients. Mean age was 50 ± 13 years (min: 19, max: 82). Both FNAB and final post-surgery histology results showed that sex and age were not statistically significantly associated with malignancy (p = 0.193) TI-RADS criteria and FNAB results revealed a statistically significant association between irregular contours, the state of anteroposterior diameter being longer than transverse diameter, microcalcifications, marked hypoechogenicity, and malignancy (p < 0,05). Thirty patients were TI-RADS ≥ 4, 206 patients were TI-RADS ≤ 3 and there was a significant correlation between TI-RADS and Bethesda classification (p = 0.001). In addition, statistically significant associations were found between malignancy and family history of thyroid cancer (p = 0.035) and radiotherapy history to the neck region (p = 0.01). CONCLUSION: TI-RADS system after nodule identification is based only on the counting of suspicious criteria. It will be safe and effective to recommend follow-up with low score TI-RADS, benign characters and insufficient FNAB results, and thus, unnecessary thyroidectomy operations will be prevented. It will be easier for surgeons to recommend surgery and persuade the patients for it when patients have high TI-RADS scores. TI-RADS has high power in detecting malignancy by recommending biopsy of suspicious nodules.

ABSTRACT

PURPOSE: To assess the relationship between MP and coexisting non-neoplastic disorders. METHODS: Consecutive abdominal computed tomography (CT) scans of 4674 patients were evaluated retrospectively for CT features of MP between January 2017 and January 2018. Clinical findings of patients were analyzed. Four control patients were selected from our cohort for each MP patient such that they matched for age, gender and CT protocol. Statistical analysis was performed using a t, Mann-Whitney U, χ2, or Fisher's test. RESULTS: 976 patients were excluded from the study due to the exclusion criteria and finally, 102/3698 patients were diagnosed with MP (mean age = 57.2 ± 12.5 years, 52% male). On CT, a hyperattenuated fatty mass (120/120), subcentimeter lymph nodes (117/120), congregation of mesenteric vessels (82/120) within the mass, a fat halo sign (28/120) and a pseudocapsule (88/120) were seen at the mesentery.The intra-observer agreement was almost perfect for the fatty mass and lymph nodes and moderate or substantial for other CT features (p < 0.001). The most prominent disorders were metabolic syndrome (MetS) and urogenital diseases in MP (45%, 37%, respectively) and control groups (31%, 26%, respectively). Between groups, no significant differences were found in the history of abdominal surgery, gastrointestinal and autoimmune diseases (p-value range 0.064-0.663); however, significant differences were found in the rates of vascular, urogenital diseases and MetS (p-value range 0.012-0.036). CONCLUSION: MetS and urolithiasis were significantly more common in patients with MP than in those without MP. Therefore, there may be a clinically relevant association between these disorders. MetS may be a risk factor for MP and urolithiasis, and treatment of metabolic disorders should be undertaken to prevent these diseases.

ABSTRACT

PURPOSE: There are many variations of the iliac vein, and it is aimed to evaluate these variations using multidetector computed tomography (MDCT). METHODS: Pelvic MDCT images of 1071 adult patients (576 males; 495 females; age range 18-94 years; mean age 50.3 years) were retrospectively evaluated. Reconstruction images of the pelvic region in sagittal and coronal planes were evaluated. Except for the usual iliac venous anatomy, all types of iliac vein connections were defined as "iliac venous variation". RESULTS: Of the 1071 patients, 84.2% were considered as type 1 (usual). Different variations were observed in 15.8% of the patients, of whom, 63.9% of were male and 36.1% female, and this gender difference was statistically significant (p < 0.05). The rates of variations detected in the study were type 2 (49.7%), type 3 (29%), type 4 (4.7%), type 5 (6.5%), type 6 (4.8%), type 7 (1.8%) and type 8 (3.6%) respectively. New subtypes that we named as type 3c, type 6f, type 6 × and type 7b were first determined in our study. CONCLUSION: Knowledge and evaluation of iliac venous variations before pelvic surgery or interventional procedures is of importance in preventing possible complications.

ABSTRACT

OBJECTIVE: The aim of this report is to share our experience and treatment outcomes with far-advanced otosclerosis (FAO) patients. METHODS: Patients that underwent surgery from 2003 through 2014 at a tertiary referral center were retrospectively reviewed. Nineteen FAO patients were included in the study. Audiological results and the ability to communicate face to face and over telephone were considered as the main outcome measures. RESULTS: Six FAO patients benefited well from stapedotomy with an average of 5.9-decibel (dB) air-bone gap and 86% median speech discrimination. Cochlear implantation (CI) was performed in 13 patients; two had disease progression after stapedotomy, five had failed stapes surgeries elsewhere, and six preferred CI as primary treatment. Median speech discrimination score of CI patients was 78.4%. Overall, all patients had satisfactory face-to-face communication and 90% could use telephone. CONCLUSION: Bilateral stapedotomy and wearing hearing aid is an effective and cost-effective solution for restoring natural binaural hearing and requires no specific training. Should stapedotomy fail, cochlear implantation is always a successful back-up option.

ABSTRACT

In patients with hemophilia, the usual treatment for both iliopsoas hematoma and associated femoral nerve compression is conservative. The case presented herein is a moderate hemophilia A patient with significant femoral neuropathy due to iliopsoas hematoma whose symptoms could not be managed with an aggressive factor VIII replacement program for >2 weeks. An unusual treatment option - percutaneous catheter insertion and aspiration of the hematoma - alleviated the examination findings and reversed his abilities.

ABSTRACT

AIMS: Obstructive sleep apnea syndrome (OSAS) is strongly related with increased risk of cardiovascular diseases andvisceral obesity. Abdominal wall fat index (AFI) is an indicator of visceral fat accumulation determined by ultrasonography(US). Carotid intima-media thickness (C-IMT) and carotid plaque score (C-PS) are the indicators of cardiovascular risk. Theaim of this study was to investigate the relation between OSAS and AFI, C-IMT or C-PS. MATERIALS AND METHODS: One-hundred and four subjects (31 females, 73 males) between 23-73year-old, candidate for polysomnography (PSG) with suspect of OSAS and without other atherosclerotic risk factor, were evaluated by US. AFI, C-IMTmean and C-PS values were determined and the subjects were grouped according to their apnea-hypopnea index (AHI) values as follows: no OSAS (<5), mild OSAS (5-15), moderate OSAS (15-30) and severe OSAS (>30). RESULTS: There was a statistically significant correlation between AFI and AHI (p=0.019). The C-IMTmean values of subjects with OSAS (AHI >5) were significantly higher than those without OSAS (AHI <5) (p=0.035). C-PS was not correlated with AHI (p=0.345) and also there was not a statistically significant difference between OSAS groups in terms of C-PS (p=0.775). CONCLUSIONS: This study revealed that AFI correlates with AHI and C-IMT increases in OSAS. The two parameters could be used as indicators of risk of metabolic disorders and atheroscleroticdiseases in subjects with sleep apnea in the future.

ABSTRACT

PURPOSE: This study aims to evaluate the morphology of the coccyx in adults with multidetector computed tomography and to contribute to the classification of the coccyx using intercoccygeal and sacrococcygeal angle measurements. METHODS: The pelvic computed tomography images of 224 patients were retrospectively evaluated. The multiplanar reconstruction and 3D volume rendering images of the coccyx were obtained from all patients at sagittal and coronal planes. The morphology of the coccyx, number of bone segments, the presence of scoliosis, and presence of sacrococcygeal and intercoccygeal fusion were evaluated. After the measurement of coccygeal length, width, and thickness, intercoccygeal and sacrococcygeal angles were also calculated in all patients. RESULTS: The morphological classification showed that 136 patients (60.7%) had type 1, 65 patients (29%) had type 2, and 17 patients (7.6%) had type 3 coccyx. The intercoccygeal angle was zero degree in five patients (type 0) and one patient had retroverted coccyx (type 5). The coccyx had four segments in 155 patients (69.2%), three segments in 52 patients (23.2%), five segments in 15 patients (6.7%), two segments in one patient (0.4%), and one segment in one patient (0.4%). CONCLUSION: We determined patients with an intercoccygeal angle of zero degree, which is not mentioned in the literature before, and we propose to use the term "type 0" for these patients in the classification of coccyx. The coccygeal measurements and classification will be instructive for the radiologists and have a guiding role for the future studies.

ABSTRACT

BACKGROUND: In cases of blunt abdominal trauma, the abdomen is the third most affected region. Computerized tomography (CT) is the gold standard for the evaluation of these patients. However, considering its damaging effects and high cost, it may not be proper to refer every patient applying to the emergency unit for a CT examination. In this study, our objective was to compare the accuracy of ultrasonography (US) and physical examination in blunt abdominal trauma patients to the gold standard CT in order to prevent unnecessary CT examinations. METHODS: In this retrospective study, the files and images of 2248 patients, who applied to the emergency department of our hospital were screened. A total of 535 adult patients who underwent CT scanning after the ultrasonographic and physical examinations were included in the study. The findings of the US and physical examinations, the intraabdominal free fluid, and organ lacerations were compared to the results of CT. The compatibility, sensitivity, specificity, positive estimated value, and the negative estimated value of the obtained data were analyzed with statistical methods. RESULTS: The sensitivity of US in the demonstration of the intraabdominal free fluid was comparable with the sensitivity of CT in the patients with blunt abdominal trauma (p=0.302). The sensitivity and specificity of US was 49.6% and 99.3% respectively in the determination of the intraabdominal organ injuries. The sensitivity and specificity of the physical examination was 59% and 87% respectively in the determination of the free fluid and organ injury as compared to CT. Although the sensitivity and specificity of the physical examination were high separately in the organ injuries according to the statistical calculations, they seemed not to have had a statistically significant predictive value (p<0.001). CONCLUSION: Even though US is a reliable method for the determination of the intraabdominal fluid, US and physical examination are not reliable in the determination of the organ injuries as compared to CT.

ABSTRACT

PURPOSE: It is aimed to present endovascular treatment of carotid blowout syndrome (CBS) in patients with head and neck cancer. METHODS: A retrospective review was performed on patients with carotid blowout syndrome between 2012 and 2018 in our hospital. A total of ten patients with prior history of head and neck cancer surgery and radiation therapy were investigated with clinical, postoperative and follow-up findings as well as technical outcome. Digital subtraction angiography of the carotid arteries was performed in all the cases for the diagnosis of the source of bleeding. Detachable coils and covered stents were used in endovascular treatment of carotid blowout syndrome. After the procedures, all patients were admitted to the intensive care unit for the follow-up of both hemodynamic and neurologic conditions. RESULTS: Thirteen diagnostic and endovascular treatment sessions were performed in 10 patients. Seven patients had major surgery for head and neck cancer and all patients were treated with chemoradiotherapy. Head and neck cancers in seven of the ten patients were persistent and pharyngocutaneous fistula developed in five patients. Two patients had impending CBS and eight patients had acute CBS. A total number of 19 vascular lesions in 10 patients were detected and 4 patients had multiple lesions. In three patients, additional endovascular treatment of stent-graft deployment had required due to recurrent hemorrhage after a mean time of 5.33 days (range 1-11 days). CONCLUSIONS: As a conclusion, covered stent application with or without coil embolization is a safe and efficient technique in treatment of CBS secondary to head and neck cancers.

ABSTRACT

The association between idiopathic intracranial hypertension (IIH) and obstructive sleep apnea syndrome (OSAS) constitutes an interesting point of discussion regarding clinical approaches as well as the underlying pathophysiological mechanisms. Here, the case of a 42-year-old female with malignant IIH and OSAS is illustrated. Initially, the patient was treated with lumboperitoneal shunt surgery. However, OSAS surgery provided total recovery from the recurrent symptoms developing secondary to lumboperitoneal shunt malfunction. The authors point out the importance of identifying OSAS as a crucial causative agent in some IIH subtypes. Future studies are warranted to clarify this underestimated association.
