Effect of Acidic Beverages on the Hardness, Elastic Modulus and Wear Resistance of Giomer and Nongiomer Bulk-fill Materials.

Objectives: The aim of this study was to evaluate and compare the effect of acidic beverages on the hardness, elastic modulus, and wear resistance of four different resin-based restorative materials.

Methods And Materials: A total of 128 specimens (10 mm diameter, 4 mm thickness) were prepared from a conventional resin composite (Filtek Z250 [Z250]), a giomer bulk-fill (Beautifil Bulk Restorative [BBR]) and two nongiomer bulk-fill materials (Tetric N-Ceram Bulk Fill [TNC] and SonicFill 2 [SF2]). Each material group was divided into four subgroups (n=8) according to the storage media: artificial saliva (control), orange juice, regular Coke, and sports drink.

Radiological manifestation of avascular necrosis (AVN) in sickle cell disease (SCD): a review of diagnostic imaging.

Symptomatic avascular necrosis (AVN) imposes a higher risk for acute care consumption in adults living with SCD. Symptomatic AVN, have higher rates of visits to the emergency department, higher rates of admissions, and longer lengths of stay in hospitals. Properly timed diagnosis and early interventions can reduce morbidity and enhance the quality of life in these patients.

Growth, bone maturation and ovarian size in girls with early and fast puberty (EFP) and effects of three years treatment with GnRH analogue (GnRHa).

Introduction: Early puberty (EP) in girls is defined as the onset of thelarche that begins after 6 years and before 8 years and/or acceleration in the tempo of pubertal development. The stage of puberty and the ovarian volume at presentation and the effect of treatment with GnRH analogue (GnRHa) on final adult height are still debated.

Patients And Methods: We analyzed the data of 22 girls, who presented early and fast puberty (FEP).

Proposed Scoring System for Evaluating Clinico-radiological Severity of COVID- 19 using Plain Chest X- ray (CXR) changes (CO X-RADS): Preliminary results.

Background: Plain chest radiograph (CXR), although less sensitive than chest CT, is usually the first-line imaging modality used for patients with symptomatic SARS-CoV-2 infection. The relation between radiological changes in CXR and clinical severity of the disease in symptomatic patients with COVID 19 has not been fully studied and there is no scoring system for the severity of the lung involvement, using the plain CXR.

Aim Of The Study: Current COVID-19 radiological literature is dominated by CT and a detailed description CXR appearances in relation to the disease time course is lacking.

Bone disease in β thalassemia patients: past, present and future perspectives.

Bone disorders in patients with thalassemia major (TM) and intermedia (TI) constitute complex conditions that result from various factors affecting the growing skeleton. Although much progress has been made in our understanding of the natural history, pathogenesis and clinical manifestations of β- and δβ-thalassemia, bone manifestations remain a puzzle for the clinician. In this review, we outline the key points in the current literature on the pathogenesis and management of bone disease in patients with TM and TI who were conventionally treated in recent decades with frequent blood transfusions and iron chelation.

Pros and cons for the medical age assessments in unaccompanied minors: a mini-review.

Unaccompanied minors refer to immigrants who are under the age of 18 and are not under the care of a parent or legal guardian. Age assessment is used in Europe mainly to establish whether or not an individual is under 18 years of age and therefore eligible for protection under the United Nations' Convention on the Rights of the Child (UN - CRC). EU Member States use a combination of techniques to determine the age of a minor and to certify minor status, including interviews and documentation, physical examinations (anthropometric assessment; sexual maturity assessment; dental observation); psychological and sociological assessment; radiological tests (carpal, dental or collarbone x-rays).

Transperineal sonographic anal sphincter complex evaluation in chronic anal fissures.

Objectives: The purpose of this study was to assess the role of transperineal sonography in assessment of pathologic changes to the anal sphincter complex in patients with chronic anal fissures.

Methods: We conducted a prospective case-control study of 100 consecutive patients of any age and both sexes with chronic anal fissures who presented to a colorectal clinic between January 2012 and August 2013 (group A) and 50 healthy volunteers (group B).

Results: The most common patterns of radiologic changes to anal sphincters associated with chronic anal fissures were circumferential thickening of the anal sphincter complex in 5 patients (5%), circumferential thickening of the internal anal sphincter in 3 patients (3%), preferential thickening of the internal anal sphincter at the 6-o'clock position in 80 patients (80%) and the 12-o'clock position in 7 patients (7%), preferential thickening of the internal and external anal sphincters in 3 patients (3%), and thinning of the internal anal sphincter in 2 patients (2%).

Comparative study between ultrasound determination and clinical assessment of the lumbar interspinous level for spinal anesthesia.

Background: The aim of the current study is to compare the accuracy of the ultrasound (US) versus clinical assessment for determination of the spinal level, using X-ray as the Gold Standard for control.

Methods: 200 patients were randomized into two equal groups. Patients in the Clinical Group were examined by landmarks to assess the Assumed Clinical Tuffier's Line, and then by fluoroscopy to determine the True Clinical Tuffier's Line.

Osteoporosis in thalassemia major: an update and the I-CET 2013 recommendations for surveillance and treatment.

In recent years, the issue of osteopenia/osteoporosis in children, adolescents and young adults with thalassaemia major (TM) has attracted much attention because it is a prominent cause of morbidity despite adequate transfusion and iron chelation therapy. The reported frequency of osteoporosis, even in well treated TM patients varies from 13.6% to 50% with an additional 45% affected by osteopenia.

Splenic Abscess: A Rare Complication of the UVC in Newborn.

Splenic abscess is one of the rarest complications of the UVC in a newborn and it is hypothesized that it could be due to an infection or trauma caused by a catheter. The case that is being reported presented with abdominal distension and recurrent desaturation with suspicion of neonatal sepsis versus necrotizing enterocolitis. However, the final diagnosis was splenic abscess as a complication of an inappropriate UVC insertion which was discovered by abdominal ultrasound.

Clinical, biochemical, and radiological manifestations of vitamin D deficiency in newborns presented with hypocalcemia.

Introduction: The Clinical and radiological manifestations of newborns with severe VDD have not been studied well.

Materials And Methods: We studied the clinical, biochemical, and radiological manifestations of 10 full-term (FT) newborns (6: M, 4: F) infant presented to with symptomatic hypocalcemia (seizure) secondary to vitamin D deficiency (VDD) during the first 10 days of life are described. All were exclusively breastfed since birth.

Growth and endocrine disorders in thalassemia: The international network on endocrine complications in thalassemia (I-CET) position statement and guidelines.

The current management of thalassemia includes regular transfusion programs and chelation therapy. It is important that physicians be aware that endocrine abnormalities frequently develop mainly in those patients with significant iron overload due to poor compliance to treatment, particularly after the age of 10 years. Since the quality of life of thalassemia patients is a fundamental aim, it is vital to monitor carefully their growth and pubertal development in order to detect abnormalities and to initiate appropriate and early treatment.

A Sacral Mass in a Newborn: A Variant of Type II Diastematomyelia with Triple Splitting of the Cord.

Ultrasonographic (US) evaluation of spinal anomalies is limited. MRI is increasingly being used in the diagnosis of spinal anomalies. MRI has been able to show clearly the detailed anatomy of this rare case of type II diastematomyelia with triple splitting of the cord.

Retroperitoneal filariasis diagnosed by fine needle aspiration: a case report.

Background: Filarial worms lodge anywhere, from body fluids to subcutaneous tissue, as various case reports prove.

Case: A 21-year-old Nepali male presented with bilateral groin swellings. Imaging studies showed dilated retroperitoneal lymphatics forming a mass, suggestive of lymphangioma or lymphangioleiomyoma.

Isolated ileocolic artery occlusion presented with segmental bowel infarction: a case report.

Acute mesenteric ischemia is a serious acute abdominal condition requiring early diagnosis and intervention to improve the outcome. Although transmural acute bowel infarction represents about 1% of all cases of acute abdomen, it has a higher annual mortality rate than colon cancer. It tends to affect the colon in segmental fashion, mostly the splenic flexure and rectosigmoid portions of the colon.

A 16-year-old boy with transfusion-dependent thalassemia major presented with tetany, numbness, bone pain, short stature and pubertal delay. His height SDS score=-2.6, BMI=22.

Review of radiologic skeletal changes in thalassemia.

The modern radiologist is unlikely to encounter the classic radiographic features of thalassemia other than in teaching files. The main pathological change that leads to radiological skeletal changes in beta thalassemia major is extensive marrow proliferation. The severity of the skeletal responses is related to the type of thalassemia, the extent and duration of the disease, the type of treatment and the volume of blood transfusions given to the patient, as well as the side effects of transfusion-chelation therapy, and also depends on the bone involved.

Linear growth, growth-hormone secretion and IGF-I generation in children with neglected hypothyroidism before and after thyroxine replacement.

We studied growth hormone (GH) stimulation and insulin-like growth factor -I (IGF-I) generation tests in 15 children with neglected congenital hypothyroidism (CH) (age = 6.4 +/- 4.2 years) and measured their growth parameters for >1 years after starting thyroxine (T4) replacement.
