Glans penis volume is associated with lifelong premature ejaculation.

BACKGROUND: Although premature ejaculation (PE) is the most common male sexual dysfunction, the underlying mechanisms are not fully understood. AIM: The study sought to evaluate the possible associations among glans penis volume and tissue stiffness measured using penile ultrasonography and penile shear wave elastography (SWE) with PE. METHODS: Men 18 to 65 years of age with normal International Index of Erectile Function scores (>25) and who were diagnosed with PE between June 2021 and June 2022 were enrolled. The Premature Ejaculation Diagnostic Tool score and intravaginal ejaculation latency times were recorded. Healthy volunteers constituted the control group. The study group was divided into lifelong PE (LLPE) and acquired PE (AqPE) subgroups. In all groups, the glans penis volume was measured via penile ultrasonography and tissue stiffness of the glans penis, penile frenulum, postcircumcision mucosal cuff, and penile shaft were measured via SWE. The findings of the groups were compared using appropriate statistical methods. OUTCOMES: The outcomes included ultrasonographic and elastographic measurements of the glans penis. RESULTS: Data on 140 men, including 70 PE patients and 70 healthy volunteers, were evaluated. Of the patients, 20 had LLPE and 50 had AqPE. The median glans penis volume was significantly greater in the LLPE group (14.1 [range, 6.6-19] mm3) compared with the AqPE group (11.7 [range, 5.1-27] mm3) and control group (11.4 [range, 6.1-32] mm3) (P = .03). According to the Youden index, the best cutoff value for glans penis volume in LLPE compared with non-LLPE (AqPE + control) was 12.65 mm3 (area under the curve, 0.684; 95% confidence interval, 0.556-0.812; P = .009). The risk of having LLPE in those with a glans penis volume ≥12.65 mm3 was 3.326 (95% confidence interval, 1.234-8.965) times higher than the non-LLPE group (P = .014). There were no significant differences between the groups in the SWE evaluation of glans penis, penile frenulum, mucosal cuff, and penile shaft tissue stiffness. CLINICAL IMPLICATIONS: The high incidence of PE in those with high glans penis volume may make glans penis volume a predictor for the development of LLPE. STRENGTHS AND LIMITATIONS: This was the first study to show that PE is more common in individuals with a high glans penis volume. It was also the first to perform a penile elastographic evaluation in patients with PE. The most important limitation was that we did not evaluate glans penile nerve function with a test, but rather we made an indirect inference about the density of free nerve endings based on increased glans penile volume. CONCLUSION: Glans penis volume was a significant predictor for LLPE. However, there are no associations between PE and the glans penis, postcircumcision mucosal cuff, penile frenulum, or penile shaft tissue stiffness and development.

Laparoscopic transperitoneal adrenalectomy for adrenal tumours of 6 cm or greater: A single-centre experience.

BACKGROUND: The present study aimed to evaluate the safety and efficacy of transperitoneal laparoscopic adrenalectomy (LA) for large adrenal tumours by comparing the outcomes of tumours larger than 6 cm with those smaller than 6 cm and also to identify the risk factors associated with prolonged operative time in transperitoneal LA. PATIENTS AND METHODS: One hundred and sixty-three patients underwent LA at our clinic from January 2014 to December 2020. Bilateral LA was performed in 20 of these 163 patients. A total of 143 patients were included in this study. Data were analysed retrospectively from the patients' medical records collected. RESULTS: Large tumour (LT) group consists of 33 patients and the small tumour (ST) group consists of 110 patients. There was no statistically significant difference between the groups regarding conversion to open surgery and complications. A multiple regression analysis was conducted to identify the independent predictors of prolonged operation time. The tumour size ≥8 cm (odds ratio [OR], 19.132; 95% confidence interval [CI], 3.881-94.303; P < 0.001) and diagnosis of pheochromocytoma (OR, 2.762; 95% CI, (1.123-6.789, P = 0.026) were the significant predictors of prolonged operation time. CONCLUSION: Our study shows that LA can be considered the treatment of choice for small and large adrenal tumours. The tumour size ≥8 cm and diagnosis of pheochromocytoma are the independent risk factors for the prolonged operative time in transperitoneal LA.

Effect of Intracameral Carbachol and Epinephrine Use on Choroidal Thickness After Uncomplicated Phacoemulsification.

BACKGROUND Safety concerns about drugs used intracamerally during cataract surgery have been the subject of many studies. In this study, the effect of using intracameral carbachol and epinephrine on choroidal thickness was evaluated. MATERIAL AND METHODS This prospective interventional study included 81 eyes of 81 patients undergoing cataract surgery. During cataract surgery, intracameral carbachol was administered to 27 eyes, intracameral epinephrine was administered to 20 eyes, and 34 eyes were the control group. Macular choroidal thickness measurement was performed before, 1 day, and 1 week after phacoemulsification surgery in all patients using optical coherence tomography. RESULTS Subfoveal choroidal thickness was significantly reduced at day 1 and week 1 in the group receiving intraoperative carbachol compared with preoperative measurement (P=0.016). In addition, choroidal thickness in the 500 µm nasal fovea was significantly reduced in the carbachol group at 1st week compared to the preoperative measurement (P=0.008). There was no significant difference in postoperative subfoveal thickness in the intraoperative epinephrine group and control group (P=0.179 and P=0.953, respectively). Choroidal thickness at 1000 µm nasal fovea was significantly higher in the epinephrine group at postoperative 1st day than preoperative and postoperative 1st week values (P=0.009). CONCLUSIONS The use of intracameral epinephrine caused an increase in choroidal thickness 1000 µm nasal of the fovea, while intracameral carbachol caused thinning in the subfoveal and 500 µm nasal quadrant. Intracameral drug administration during cataract surgery may be associated with posterior segment complications.

New onset atrial fibrilation and risk faktors in COVID-19.

BACKGROUND: There is limited data concerning the prevalence of arrhythmias, particularly atrial fibrillation (AF), which may develop as a consequence of direct myocardial injury and the inflammatory state existing in COVID-19. METHODS: This single-center study included data concerning 658 COVID-19 patients, who were hospitalized in our institute, between April 20th, 2020 and July 30th, 2020. Demographic data, findings of the imaging studies, and laboratory test results were retrieved from the institutional digital database. RESULTS: New onset AF (NOAF) was identified in 33 patients (5%). Patients who developed AF were older (72.42 ± 6.10 vs 53.78 ± 13.80, p < 0.001) and had higher frequencies of hypertension and heart failure compared to patients without NOAF (p < 0.001, for both). The CHA2DS2-VASc score was higher in patients, who developed NOAF, compared to those who did not during hospitalization for COVID-19 (p < 0.001). Subjects, who developed NOAF during hospitalization, had a higher leukocyte count, neutrophil / lymphocyte ratio (NLR), C-reactive protein, erythrocyte sedimentation rate, and procalcitonin levels compared to those without NOAF (p < 0.001 for all comparisons). Diffuse lung infiltration was also more frequent in COVID-19 patients, who developed NOAF, during hospitalization (p = 0.015). Multivariate logistic regression analysis demonstrated that age, CHA2DS2-VASc score, CRP, erythrocyte sedimentation rate, and presence of diffuse lung infiltration on thorax CT were predictive for NOAF. CONCLUSION: The prevalence of NOAF in hospitalized COVID-19 patients is higher than the general population. Age, CHA2DS2-VASc score, C-reactive protein, erythrocyte sedimentation rate, and presence of diffuse lung infiltration on thorax CT may be used to identify patients at high risk for development of NOAF. Especially among these parameters, the presence of diffuse lung infiltration on thorax CT it was the most powerful independent predictor of NOAF development.

The evolution of the changes in the clinical course: a multicenter survey-related impression of the ophthalmologists at the peak of the COVID-19 pandemic in Turkey.

PURPOSE: The coronavirus disease-2019 (COVID-19) has become a difficult pandemic to control worldwide. The high transmission risk and mortality rates of COVID-19 cause serious concerns in ophthalmologists and may cause disruptions in clinical functioning. This study aims to identify changes in the clinical approaches of ophthalmologists, understand their anxiety levels, and exhibit how patients' follow-up processes progress during the pandemic. METHODS: A questionnaire that including demographic information, ophthalmology clinical activity scale, and Beck anxiety scale was sent to ophthalmologists in Turkey. Google Forms was used as a survey platform in this study. RESULTS: A total of 121 ophthalmologists participated in the study. The participants stated that they could not continue routine interventional diagnosis and treatment practices during the outbreak. It was clearly stated that there were changes in their clinical approach and decreased patient examination quality. For this reason, 14.9% of physicians said to missed the diagnosis in this process. Physicians who encounter infected patients state that it is more difficult to provide ophthalmological services and their clinical approaches are affected more negatively. Anxiety levels of physicians who could access personal protective equipment (PPE) and show positive solidarity with their colleagues in the process were found to be lower. CONCLUSION: Our study revealed that ophthalmologists, like other healthcare professionals, were severely affected by the COVID-19 outbreak. Accordingly, healthcare managers should provide adequate PPE for ophthalmologists, organize the clinical operation, and support the mental health of ophthalmologists.

Retinal nerve fibre and ganglion cell inner plexiform layer analysis by optical coherence tomography in asymptomatic empty sella patients.

Purpose: To investigate the clinical importance of the thicknesses of the retinal nerve fibre (RNFL) and ganglion cell and inner plexiform layer (GCL+) by spectral domain optic coherence tomography (SD-OCT) in asymptomatic empty sella (ES) patients.Materials and methods: In this cross-sectional, non-randomized prospective study, 44 ES patients and 74 age- and sex-matched healthy individuals were evaluated. All the patients and controls competed an automated 30-2 visual field (VF) test. The mean deviation (MD), pattern standard deviation (PSD), RNFL, and GCL + thickness values obtained with SD-OCT were compared statistically between the two groups.Results: No marked VF defects were found in either group, and there was no statistically significant between-group difference in MD or PSD values. In terms of RNFL thickness, the average and superior quadrant RNFL values of the ES patients were thinner than those of the controls, with statistical significance (p = 0.013 and p = 0.043, respectively). Although other measured RNFL quadrant thicknesses and foveal thickness (FT), macular volume (MV), and average macular thickness (AMT) values were reduced in the ES group, these differences were not statistically significant. The average GCL + value and GCL + values in six sectors in the patient group were significantly lower than those in the control group.Conclusions: Asymptomatic ES patients have a risk of primary ES syndrome and should be followed up using a multidisciplinary approach. Objective and quantitative RNFL and GCL + thickness measurements obtained with OCT can provide valuable data for monitoring these patients.

Pre-procedural shear wave elastography on prediction of hemorrhage after percutaneous real-time ultrasound-guided renal biopsy.

PURPOSE: To evaluate the relationship between renal elasticity which was determined with shear wave elastography (SWE) and hemorrhage in patients who undergone percutaneous renal parenchyma biopsy (PRB). MATERIALS AND METHODS: In total, 60 patients who were performed ultrasound-guided PRB after the B-mode ultrasonography and SWE assessment were recruited in this study. All patients' serum creatinine, blood urea nitrogen and coagulation tests before PRB were obtained from medical records. The patients were divided into two groups who did and did not develop hemorrhage after PRB. We investigated whether there was any statistically significant difference between the two groups in terms of laboratory findings, B-mode ultrasonographic measurements and SWE measurements. RESULTS: Of the 60 patients, 23 (38.3%) had post-procedure hemorrhage and 37 (61.7%) had not. Mean hemorrhage size was 17.04 mm (7-50 mm). The mean value of renal cortical shear wave velocity of all patients was 1.91 m/s (0.96-3.57 m/sn). Patients with post-procedure hemorrhage had significantly lower mean shear wave velocity compared with patients with no hemorrhage (p < 0.05). ROC curve analysis suggested that the optimum SWV cutoff point for hemorrhage presence was 1.21 m/sn, with 39.1% sensitivity and 97.3% specificity. There was no other statistically significant demographic, ultrasonographic or laboratory value differences between two groups. CONCLUSION: Although shear wave velocities have low sensitivity for hemorrhage after renal biopsy, high specificity and statistically significant difference in hemorrhage and non-hemorrhage group suggest that patients who have lower renal cortical shear wave velocity have a tendency to hemorrhage after PRB.

The Efficacy of Extracorporeal Shock Wave Therapy for Chronic Coccydynia.

OBJECTIVE: Coccydynia is a disorder that decreases quality of life with significant functional failure. Extra-corporeal shock wave therapy (ESWT) is used to treat several painful musculoskeletal disorders. SUBJECTS AND METHODS: The medical records of 34 patients (29 females, 5 males) who had been treated with ESWT between 2017 and 2018 for chronic coccydynia were evaluated. Visual analog scale (VAS) scores were noted at the initial consultation, at each session, and during the initial and follow-up (at 6 months) examinations after the treatment. The 36-item short form (SF-36) quality of life scale survey was conducted at the beginning and end of the treatment. MRI was performed before the start of the procedure and 1 month after the end of the treatment. RESULTS: The mean VAS score was 9.6 (9-10) before the treatment and 3.4 (0-2) after the treatment (p < 0.05). The VAS score decreased to ≤3 in 79.4% of patients. Bone marrow edema regressed in 6% of patients. Significant improvement was observed in all of the SF-36 parameters, except for two. CONCLUSION: In our patient group, ESWT provided effective pain control. In order to evaluate the efficacy of ESWT more accurately and sensitively, prospective randomized studies with longer follow-up periods, in which ESWT is compared with different energy doses and different treatment methods, are needed.

The impact of intravitreal dexamethasone implant (Ozurdex®) on retrobulbar hemodynamics in patients with diabetic macular edema and retinal vein occlusions.

Objective: To evaluate the effect of single intravitreal dexamethasone implant (Ozurdex®) on ocular blood flow velocities in patients with diabetic macular oedema (DME) and retinal vein occlusions (RVO). Methods: This prospective non-randomized interventional study included injected and fellow eyes of 12 patients with DME and of 16 patients with RVO treated with intravitreal Ozurdex®. Colour Doppler Ultrasonography (CDU) measures of the central retinal artery (CRA), posterior ciliary artery (PCA), ophthalmic artery (OA) those are peak systolic velocity (PSV), end diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) were performed in both injected and uninjected eyes before injection, at one week, one month after injection, and prior to re-injection. Results: Inter-eye comparison of all the measured CDU data (baseline, first week, first month, reinjection) showed no statistically significant difference in both DME and RVO group. PSV and EDV values of the CRA, OA, and PCA showed a decreasing trend in the first week and first-month visits and then increased at reinjection time. RI and PI measures of the CRA, OA, and PCA measures showed minimal alterations in the follow-up. But all these differences were not statistically significant. Significant visual gain and anatomic recovery were obtained by the intravitreal dex-implant both in the DME and RVO group. Conclusions: Single intravitreal dex-implant did not alter ocular blood flow in the treatment of macular oedema due to RVO and diabetes.

Effect of intravitreal aflibercept (Eylea®) on retrobulbar hemodynamics in patients with neovascular age-related macular degeneration.

PURPOSE: To investigate the short-term effect of single intravitreal aflibercept injection on retrobulbar blood flow in patients with neovascular age-related macular degeneration (nAMD). METHODS: Twenty eyes of 20 patients with nAMD scheduled for single intravitreal aflibercept (Eylea®) injection and 20 fellow eyes (uninjected) were enrolled in this prospective interventional study. The hemodynamic parameters of the ophthalmic artery (OA), central retinal artery (CRA) and posterior ciliary artery (PCA) comprising peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) were measured by using color Doppler ultrasonography (CDU) in both injected and uninjected fellow eyes at baseline and 1 week after the injection. RESULTS: The measured first-week values of PSV and EDV in the CRA, OA and PCA showed a statistically significant reduction when comparing baseline values in both injected and uninjected fellow eyes (p = 0.0001). Also, it was found a significant increase in the post-injection RI values of all the CRA, OA, PCA in injected eye and OA in the uninjected eye (p = 0.0001). There was any significant difference between pre- and post-injection RI values of the CRA and PCA in the fellow eyes (p = 0.137, p = 0.736, respectively). CONCLUSION: Single intravitreal administration of aflibercept alters retrobulbar blood flow velocities (BFVs) in both injected and uninjected fellow eyes in the short-term period.

Macular ganglion cell-inner plexiform layer thickness for detection of early retinal toxicity of hydroxychloroquine.

PURPOSE: This study evaluated the macular ganglion cell-inner plexiform layer (GC-IPL) thickness using spectral-domain (SD) optical coherence tomography (OCT) in patients with chronic exposure to hydroxychloroquine (HCQ). METHODS: A total of 90 patients (90 eyes) treated with HCQ for at least 5 years and normal controls were included in the study. A fundus examination, automated threshold perimetry, and GC-IPL thickness measurements using the Cirrus high-definition OCT ganglion cell analysis algorithm were performed in all patients treated with HCQ. Average, minimum, and sectorial macular GC-IPL thicknesses were compared between the patients and controls. RESULTS: There was no statistically significant difference in age or sex between the groups. The anterior segment and fundoscopy were normal in all patients and controls. Visual field (VF) testing was normal in all patients. The average, minimum, and sectorial macular GC-IPL thicknesses were significantly lower in patients than those in control subjects. CONCLUSIONS: There was significant thinning of the macular GC-IPL in the absence of clinically evident HCQ-related retinopathy and VF abnormalities. Measurements of the macular GC-IPL thickness using SD-OCT may therefore be useful in the early diagnosis and in monitoring the progression of retinal changes in patients receiving long-term HCQ therapy.

Effect of topiramate on choroidal thickness and anterior chamber parameters in the treatment of patients with migraine.

OBJECTIVE: To investigate the effects of topiramate on choroidal thickness and anterior chamber parameters using optical coherence tomography in the treatment of patients with migraine. METHODS: A total of 22 eyes of 22 adults (12 females, 10 males) diagnosed with migraine and scheduled to topiramate treatment for pain control were recruited in this prospective study. Choroidal thickness (CT), anterior chamber depth (ACD), anterior chamber angle (ACA), spherical refractive equivalent (SphEq) and intraocular pressure (IOP) measurements were recorded at baseline (prior the topiramate therapy), first and second month visits for the statistical analysis. One-way ANOVA with repeated measures test was used for the statistical evaluation. RESULTS: Mean age of the patients was 40.2 ± 6.5 years. Mean CT at central fovea was 324 ± 47 µm initially, 341 ± 45 µm in the first month and 344 ± 46 µm in the second month, thus first and second month measures were significantly higher than base values (p < 0.001). There was also a slight increase in IOP values among baseline (15.5 ± 2.4 mmHg) and follow-up visits (17.5 ± 2.6 mmHg, 19.0 ± 3.3 mmHg, respectively, ` p = 0.001). Baseline ACD (3.66 ± 0.22 mm) measures significantly decreased at the first month (3.63 ± 0.22 mm) and second month (3.62 ± 0.22 mm, p = 0.009). Also, a significant reduction was detected in the first (36.2 ± 4.9°) and second month (35.9 ± 5.1°) ACA measures comparing with baseline (39.1 ± 5.1°, p = 0.05). A significant myopic shift was determined in the first and second month SphEq values (-0.08 ± 0.6, -0.10 ± 0.6, respectively, p = 0.05). CONCLUSIONS: The study revealed increased CT and altered anterior chamber parameters and IOP due to topiramate therapy. Therefore, the patients using topiramate should be carefully monitored by an ophthalmologist considering the possible side effects.

Effect of eye trauma on mental health and quality of life in children and adolescents.

The purpose of this study is to evaluate the effects of eye traumas on mental health and quality of life of children, adolescents, and their parents. Medical records of 20 children and adolescents presented with blunt and open eye injuries between June 2009 and May 2014 were reviewed. Demographics of patients, timing and type of trauma, findings of initial examination, and medical and surgical interventions applied were recorded. To detect mental health, "Affect disorders and schizophrenia interview chart for school children, now and lifelong" (AFSIC-NL) and "Child Post-Traumatic Stress Reaction Index (CPTSD-RI)" were used. "Pediatric scale of quality of life" (PedsQL) was used to assess quality of life for both parents and children. According to AFSIC-NL, 9 patients were diagnosed with mental disorders including posttraumatic stress disorder (n = 3, 15 % patients), generalized anxiety disorder (n = 3, 15 % patients), and major depression (n = 3, 15 % patients). The PedsQL values of both children's and parents' were at their lowest in school and physical health domains for children and in physical health domain for parents. A reverse correlation was detected between the number of surgeries and PedsQL-child physical functionality, school functionality, psychosocial functionality, and total scale point. There was a statistically significant relationship between initial visual acuity or lens damage and PedsQL-parent emotional functionality scale. Regarding CPTSD-RI, the parents of these patients have a mild posttraumatic stress disorder. Eye injuries can lead development of psychopathology in children. Therefore, psychiatric support must be provided in follow-up period for these patients.

Carotid Intima-Media Thickness as the Cardiometabolic Risk Indicator in Patients with Nonfunctional Adrenal Mass and Metabolic Syndrome Screening.

BACKGROUND: Our purpose was to show the association of adrenal incidentaloma and metabolic syndrome in consideration of the studies and to detect the increase in the carotid intima-media thickness which is regarded as the precessor of atherosclerosis. MATERIAL/METHODS: Eighty-one patients who were diagnosed with adrenal mass were included in the study. Hormonal evaluation, insulin rezistance measurement with the HOMA-IR and 1-mg DST were performed of all patients. The patients were classified as follows: mass size <3 cm (K1) and mass size of at least 3 cm (K2). Echocardiography and carotid intima-media thickness of the patients were measured using B-mode ultrasound. Thirty-three healthy individuals were enrolled as the control group. RESULTS: Mass size of 64.19% K1, while mass size of the remainder (35.81%) K2 was calculated. Five of the patients with adrenal mass were detected to have subclinical Cushing syndrome. The remaining 76 patients were accepted as nonfunctional. It was seen with regard to metabolic and biochemical parameters that plasma glucose (p=0.01), insulin (p=0.00) and triglyceride (p=0.012) values of all patients were significantly high compared to those of the control group. It was detected that measured heart rate (p=0.00), end-diastolic diameter (p=0.02), end-systolic diameter (p=0.014) and carotid intima-media thickness (p=0.00) values of the patients with adrenal mass were significantly higher than those of the healthy control group. CONCLUSIONS: We found that the increased insulin resistance, increased risk of cardiovascular disease with the increase in the thickness of carotid intima-media and diastolic disfunction parameters, although the patients with adrenal incidentaloma are nonfunctional.

Comparison of hyperbaric oxygen versus iloprost treatment in an experimental rat central retinal artery occlusion model.

PURPOSE: Central retinal artery occlusion (CRAO) is one of the serious ophthalmological emergencies with poor visual prognosis. Iloprost is a stable prostacyclin analogue and has prominent anti-edema, anti-inflammatory, vasodilatory, and antiagregant effects. The main objective of this work was to investigate iloprost as an alternative agent versus hyperbaric oxygen (HBO) in the treatment of CRAO. METHODS: Twenty-eight healthy Wistar albino male rats were randomly assigned into control (n = 7, sham operation), HBO (n = 7), iloprost (n = 7), and sham groups (n = 7). CRAO model was created through optic nerve exploration and ligation. Full-thickness retina (FTR), outer nuclear layer (ONL), inner nuclear layer (INL) and ganglion cell layer (GCL) thickness were measured on Hematoxylin/Eosin (H&E) stained retinal sections and immunohistochemical analysis including terminal deoxynucleotidyl transferase-mediated biotindeoxyuridine triphosphate nick-end labeling (TUNEL) assay was performed to determine the apoptotic index (AI). RESULTS: AI values of HBO (0.204 ± 0.067) and iloprost (0.197 ± 0.052) groups were significantly lower than sham (0.487 ± 0.046) group (p < 0.001). Any significant difference was found between the HBO and iloprost groups in terms of AI (p = 0.514). A statistically significant increase in thickness of FTR, ONL, INL and GCL was detected in HBO, iloprost and sham groups compared to the control group (p = 0.002). FTR, ONL, INL and GCL thickness were significantly thinner in HBO and iloprost groups than in the sham group (p = 0.002). A significant lesser increase was observed in all the retinal layers thickness in iloprost group versus HBO group (p = 0.002) except for INL (p = 0.665). CONCLUSIONS: The study results demonstrated anti-edema, neuroprotective, and anti-apoptotic effects of iloprost quantitatively; thus, iloprost may be a beneficial alternative agent in the treatment of CRAO.

Successful One Stage Surgical Removal of Intravenous Leiomyomatosis with On Pump Beating Heart Technique.

An intravenous leiomyomatoma is a rare benign smooth muscle tumour originating from myometrial veins. Surgical resection is the best treatment for intracardiac extension of intravenous leiomyoma. Here we present a very rare case of intravascular and intracardiac leiomyomatosis. We successfully performed one-stage surgery to remove the leiomyomatosis with beating heart under cardiopulmonary bypass.

The Avaibility of Strain Elastography in a Hydatid Cyst - Interobserver Study.

BACKGROUND: To differentiate the hydatid cyst (HC) types by ultrasound elastography using two different sizes (4 mm and 8 mm) of the region of interest (ROI) and asking two different radiologists (interobserver) for their opinion. MATERIAL/METHODS: Patients with HC were evaluated by USG elastography. The statistical anayses were performed using Strain index (SI) which is the unit of strain elastography. RESULTS: A total of 26 out of 33 patients were female, and 7 were male. The mean age was 38.85±17.62 (range from 10 to 72 years). Type I: 6, Type 2: 6, Type III: 6, Type IV: 11, Type V: 4. There was no significant difference in HC SI (regardless of types) between O1 and O2, and 4-mm and 8-mm ROI (p>0.05). There was no statistically significant difference between SI of HC types of interobservers (O1-O2) and ROI sizes (4-8 mm) (p>0.05 for all parameters). The highest correlation between HC types and ROI sizes was in ROI size of 4 mm. CONCLUSIONS: The correlation between SI and types was reliable in standard-applied 4-mm ROI. There was no statistically significant difference between interobservers in SI values. Thus, elastography tecnhnique is objective for HC but not appropriate to differentiate the types.

Assessment of Thyroid Gland in Children with Point-of-Care Ultrasound (POCUS): Radiological Performance and Feasibility of Handheld Ultrasound in Clinical Practice.

Background: Point-of-Care Ultrasound (POCUS) refers to the use of portable ultrasound machines to perform quick and focused ultrasound examinations at a patient's bedside or point-of-care. POCUS can be performed by all health workers with specific training to use POCUS. This study aimed to investigate the radiological performance and feasibility of POCUS using a handheld ultrasound (HHUSD) system in children from the perspective of the thyroid gland perspective. Material-Methods: A pediatric endocrinologist performed thyroid imaging in children referred to our hospital with suspected thyroid disease using an HHUSD system. The same children underwent US imaging using the same device by the first radiologist, and a second radiologist performed thyroid US using an advanced high-range Ultrasound Device (AHUSD) (defined as the gold-standard method) within two hours. The data obtained by the three researchers were compared with each other. Results: This study included 105 patients (68.6% girls [n=72)]; mean age 12.8±3.6 years]. When the thyroid volume was evaluated, a strong correlation was found between the measurements of the three researchers (AA vs. MG: r=0.963, AA vs. GT: r=0.969, MG vs. GT: r=0.963, p<0.001). According to the Bland-Altman analysis, for total thyroid volume, AA measured 0.43 cc (%95 CI: -0.89-0.03) smaller than MG, and 0.11 cc (%95 CI: -0.30-0.52) larger than GT, whereas MG measured 0.52 cc (%95 CI: 0.09-0.94) larger than GT. When evaluated for the presence of goiter and nodules, a near-perfect agreement was found between the results of the three researchers (AA vs GT; κ=0.863, MG vs GT; κ=0.887, p<0.001, and AA vs GT; κ=1.000, MG vs GT; κ=0.972, p<0.001, respectively). When evaluated in terms of the longest axis of nodules, a high correlation was found between the measurements of the three researchers (AA vs MG; r=0.993, AA vs GT; r=0.996, MG vs GT; r=0.996, p<0.001). When evaluated in terms of the final diagnosis, the evaluations of the three researchers showed excellent agreement with each other (AA vs GT; κ=0.893, MG vs GT; κ=0.863, p<0.001, Accuracy rate AA vs GT: 93.3%; MG vs GT: 91.4%). Conclusion: A pediatric endocrinologist, equipped with sufficient training in thyroid US evaluation, incorporates the HHUSD as a routine tool for clinical examinations in outpatient settings, they can effectively assess normal thyroid tissue in pediatric patients. Moreover, the HHUSD system proves to be useful in detecting thyroid pathologies. However, it is crucial to note that for a more comprehensive evaluation of thyroid nodules, including detailed assessment and Thyroid Imaging Reporting and Data System "TIRADS" classification, patients should be referred to radiology departments equipped with AHUSD systems. These specialized devices, along with the expertise of radiologists, are essential for in-depth evaluations and accurate classification of thyroid nodules.

Thyroid volume in Turkish school-age children living in an iodine-sufficient region.

OBJECTIVES: We aimed to obtain local normative data on thyroid volume evaluated by ultrasonography and iodine status by measuring urine iodine levels in school-age children living in Aydin province. METHODS: In this cross-sectional study, a sample comprising 1,553 cases was meticulously selected from a total cohort of 170,461 children aged 6-17, drawn from 21 distinct educational institutions located within the Aydin region, as participants in the investigation. Those with a known chronic disease or thyroid disease were excluded from the study. The children underwent physical examinations and ultrasonography imaging of the thyroid gland, and urine samples were collected to measure urinary iodine concentration (UIC). RESULTS: The median UIC was 189.5 (IQR=134.4) µg/L, which was optimal according to WHO criteria. Thyroid volume was found to be 4.6 (IQR=3.5) mL in girls and 4.2 (IQR=4.0) mL in boys (p=0.883). The thyroid volumes in our study were found to be smaller when compared to the WHO. According to WHO age and body surface area criteria, thyroid volume was over 97 % in 0.9 % (n=15) of cases. Thyroid volume was found to have a positive correlation with age, height, weight, body mass index (BMI), and body surface area (BSA) in both genders (p<0.001). However, there was no significant correlation between thyroid volume and UIC. CONCLUSIONS: This cross-sectional study provides normative data on thyroid volume and iodine status in school-age children in iodine-sufficient population, revealing a low prevalence of goiter and correlations between thyroid volume and anthropometric measures.

Associations of Adipocyte-derived Versican and Macrophage-derived Biglycan with Body Adipose Tissue and Hepatosteatosis in Obese Children

Objective: In animal models of obesity, adipocyte-derived versican, and macrophage-derived biglycan play a crucial role in mediating adipose tissue inflammation. The aim was to investigate levels of versican and biglycan in obese children and any potential association with body adipose tissue and hepatosteatosis. Methods: Serum levels of versican, biglycan, interleukin-6 (IL-6), and high sensitivity C-reactive protein (hsCRP) were measured by ELISA. Fat deposition in the liver, spleen, and subcutaneous adipose tissue was calculated using the IDEAL-IQ sequences in magnetic resonance images. Bioimpedance analysis was performed using the Tanita BC 418 MA device. Results: The study included 36 obese and 30 healthy children. The age of obese children was 13.6 (7.5-17.9) years, while the age of normal weight children was 13.0 (7.2-17.9) years (p=0.693). Serum levels of versican, hsCRP, and IL-6 were higher in the obese group (p=0.044, p=0.039, p=0.024, respectively), while no significant difference was found in biglycan levels between the groups. There was a positive correlation between versican, biglycan, hsCRP, and IL-6 (r=0.381 p=0.002, r=0.281 p=0.036, rho=0.426 p=0.001, r=0.424 p=0.001, rho=0.305 p=0.017, rho=0.748 p<0.001, respectively). Magnetic resonance imaging revealed higher segmental and global hepatic steatosis in obese children. There was no relationship between hepatic fat content and versican, biglycan, IL-6, and hsCRP. Versican, biglycan, hsCRP, and IL-6 were not predictive of hepatosteatosis. Body fat percentage >32% provided a predictive sensitivity of 81.8% and a specificity of 70.5% for hepatosteatosis [area under the curve (AUC): 0.819, p<0.001]. Similarly, a body mass index standard deviation score >1.75 yielded a predictive sensitivity of 81.8% and a specificity of 69.8% for predicting hepatosteatosis (AUC: 0.789, p<0.001). Conclusion: Obese children have higher levels of versican, hsCRP, and IL-6, and more fatty liver than their healthy peers.
