Surgical and Prosthetic Management of a Juvenile Ossifying Fibroma In a 5-Year-Old Child: A Clinical Report

Juvenile ossifying fibroma (JOF) is a rare and benign fibro-osseous lesion of the craniofacial skeleton commonly seen in children under 15 years of age. Despite being classified as benign, JOF lesions are aggressive in nature and reach large dimensions in a short period of time. Thus, their resections may cause large orofacial defects which have serious detrimental effects on the functional and nutritional requirements of pediatric patients being in the period of growth. Therefore, its early diagnosis and proper surgical and prosthetic management are of vital importance for the survival of patients. However, no detailed reports in the literature describe the prosthetic management of large intraoral defects in pediatric patients under 10 years old

Impact of transcatheter aortic valve implantation on the left ventricular mass

Background: Aortic stenosis (AS) induces pressure overload of the left ventricle (LV) and results in left ventricular hypertrophy. The remodeling of the LV in patients with AS is a com­plex process including structural and functional disturbances. After aortic valve replacement, reverse remodeling of LV begins. The aim of this study was to evaluate the impact of transcatheter aortic valve ımplantation (TAVI) on LV mass (LVM) in early and mid-term follow-ups after the procedure. Methods and Results: We enrolled consecutive 75 patients who underwent successful TAVI. Transthoracic echocardiography was performed prior to TAVI and at hospital discharge, in the 1st month and 6th month of the follow-ups. The mean LV ejection fraction improved significantly after TAVI (54.2 ± 15.0% to 57.3 ± 11.7%, p < 0.001). There were no significant changes between the baseline and discharge mean LVM and LVM index values (LVMI; p = 0.1). However, LVMI decreased significantly in the 1st month of follow-up compared to baseline (123.3 ± 20.3 to 127.9 ± 21.3 g/m2, respectively, p < 0.001). Also, significant regression of LVM was observed at the 1st month of follow-up compared to baseline (228.3 ± 33.5 g vs. 236.5 ± 34.2 g, respectively, p < 0.001). Furthermore, the significant regression in both of LVM and LVMI continued at 1st and 6th months of the follow-ups (p < 0.001). Conclusions: A significant regression of LVM was observed after TAVI. These changes may have prognostic value in patients with severe AS

Immediate recovery of the left atrial and left ventricular diastolic function after transcatheter aortic valve implantation: A transesophageal echocardiography study

Background: Chronic increased afterload due to severe aortic stenosis (AS) results in com­pensatory concentric left ventricular (LV) hypertrophy and LV dysfunction. These in turn cause remodeling of the left heart. The aim of this study was to investigate the acute effect of transcatheter aortic valve implantation (TAVI) on left atrial (LA) mechanics and LV diastolic function. Methods: The study consisted of a total of 35 consecutive patients (mean age was 77.7 ± 5.0 years, 25 female) undergoing TAVI. All TAVI procedures have been performed under the transesophageal echocardiography (TEE) guidance. Before and 24 h after TAVI, all patients underwent transthoracic echocardiography (TTE) and mitral inflow velocities with pulsed-wave (PW) Doppler including early filling wave (E), late diastolic filling wave (A), and E/A ratio were obtained. LV diastolic function was also explored by pulsed tissue Doppler imaging (TDI). Early (E’) and late (A’) diastolic annular velocities, E’/A’ ratio and E/E’ ratio were obtained. In addition, during the procedure before and minutes after the valve implantation, the left atrial appendage-peak antegrade flow velocity (LAA-PAFV) was measured and recorded with TEE. Results: Compared with baseline, the mean mitral E, septal E’ and E’/A’ ratio increased significantly after TAVI. In addition, the LAA-PAFV increased significantly within minutes of TAVI (32.45 ± 10.7 cm/s vs. 47.6 ± 12.6 cm/s, p < 0.001). Conclusions: TAVI improves LV diastolic function and LA performance immediately

Impact of transcatheter aortic valve implantation in patients with reduced ejection fraction

Background: Aortic stenosis increases with age. According to guidelines, left ventricular systolic dysfunction is an indication for aortic valve replacement, even in asymptomatic patients. There is no clear data on the application of transcatheter aortic valve implantation (TAVI), which is a method showing continuous improvement in recent years, in patients with reduced ejection fraction (REF) having a poor prognosis for surgical aortic valve replacement. We therefore aimed to investigate the effect of TAVI on left ventricular ejection fraction (LVEF) and also its efficacy and safety in patients with REF. Methods and results: The study included 104 patients who underwent transfemoral TAVI in our clinic. The patients were divided into two groups: LVEF ≤ 45% (REF group, n = 28) and LVEF > 45% (preserved ejection fraction [PEF] group, n = 76). Follow-up measure­ments were performed at baseline, discharge, 1st, 6th and 12th months. No statistical difference was found between the groups with respect to complications and mortality rates. A statistically significant difference was detected in LVEF after TAVI, either in all patients (53.9 ± 14.6, 57.0 ± 11.4, 59.4 ± 8.4, 60.4 ± 6.8, 63.2 ± 3.9, respectively, at baseline, discharge, 1st, 6th and 12th months, p < 0.001) or in the groups separately. A statistically significant increase in LVEF (p < 0.001) was determined at discharge, 1st, 6th and 12th months, whereas LVEF increased in all follow-ups of the PEF group, however this elevation reached a statistical significance only at the 1st month (p = 0.04). Conclusions: Our study has shown the positive effect of TAVI on LVEF and its effective and safe applicability in patients with REF.

Primary parotid tuberculosis mimicking parotid neoplasm: a case report

<p>Abstract</p> <p>Introduction</p> <p>Tuberculosis of the parotid gland is a rare clinical entity which causes some difficulties in diagnosis because of the similarities in presentation to that of a neoplasm. Diagnosis mainly relies in the treating physician having a high index of suspicion. The diagnosis is generally overlooked by otolaryngologists and most cases are undergoing unnecessary surgery.</p> <p>Case presentation</p> <p>A 20-year-old male presented with a mass in the right parotid region. The mass had been present for one year. Physical examination revealed a mobile, non-tender mass occupying the superficial lobe of the right parotid gland. Radiologic investigations revealed a well-defined, solid, mass lesion located in the posterior part of the superficial lobe of the right parotid gland. A provisional diagnosis of a neoplasm of the parotid gland was made and a right superficial parotidectomy was performed. Histopathologic examination of the specimen was reported as tuberculosis of the parotid gland. The patient was commenced on antitubercular chemotherapy.</p> <p>Conclusion</p> <p>Although rare, tuberculosis should be kept in mind and considered in the differential diagnosis of patients presenting with a solitary tumor in the parotid gland in order to avoid unnecessary surgery.</p

Fibrous dysplasia as a rare cause of nasolacrimal duct obstruction

Fibrous dysplasia of the paranasal sinuses is mostly asymptomatic, but sometimes may cause signs and symptoms de- pending on its location. We report two cases of maxillary fibrous dysplasia obstructing the lacrimal drainage system as a reason of chronic dacryocystitis, and reviewed the related literature. The first case underwent an endonasal endoscopic approach combined with external dacryocystorhinostomy. He had a patent lacrimal system at one-year follow-up. The le- sion was completely removed via an endonasal endoscopic approach in the second case, wherein the patient was asymp- tomatic of the six-month follow-up period.

Osteoma and Ectopic Tooth of the Left Maxillary Sinus: A Unique Coexistence

Background: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. Case Report: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell- Luc procedure. Conclusion: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma. Pediatric patients with maxillofacial trauma should be carefully watched for dental injury both clinically and radiologically
