Patrick C Bonasso, Lori A Gurien, Samuel D Smith, Marie E Saylors, M Sidney Dassinger
BACKGROUND: Variation exists in pediatric vascular trauma management. We aim to determine practice patterns for vascular trauma management at American College of Surgeons (ACS) verified pediatric trauma centers and evaluate the resources available for management of vascular trauma at both freestanding children's hospitals (FSCH) and pediatric hospitals within general adult hospitals (PHGAH). METHODS: Pediatric surgeons and trauma medical directors at ACS designated pediatric surgery trauma centers completed a survey designed to evaluate anticipated management of traumatic arterial injuries and resource availability...

Background: The components of soft tissue are fibroblasts, collagen, vascular structures, fatty tissue, skeletal muscles, smooth muscles, and neural tissue. The real incidence of soft tissue tumors (STTs) is difficult to estimate because most of them are benign (Benign: Malignant-100:1). Aims: The aim of the present study was undertaken to note the patterns of presentation of patients with STTs and to evaluate the findings of imprint cytology (IC) and histopathological examination (HPE) of STTs...

PURPOSE: Adrenocortical lesions are characterized through imaging, hormonal and histopathological analysis. Our aim was to compare the radiological features of adrenocortical lesions with their cortisol-secreting status and histopathological Weiss score. METHODS: Seventy five patients operated between 2004 and 2016 in the University Hospital of Nancy for either adrenocortical carcinomas (ACC) or adrenocortical adenomas (ACA) were enrolled in this study. We collected cortisol parameters, Computed Tomography (CT) scans (unenhanced density, wash-out (WO) analysis) and 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) datas...

INTRODUCTION: The most common surgical treatment of traumatic spine fractures is through a posterior approach using pedicle screws and rods. Postoperative treatment protocols including the use of postoperative orthoses however differ between hospitals and surgeons. A three-point hyperextension orthosis is designed to support proper posture and unload the anterior column. Some motion remains when wearing an orthosis, and its main value in postoperative treatment is therefore believed to be pain relief and patient confidence...

This study aimed to measure the equilibrium equivalent radon (EECRn) concentration in an old building (Building-1) and a new building (Building-2) with mechanical ventilation and a natural ventilation system, respectively. Both buildings were located at the campus of University Kebangsaan Malaysia. The concentration of indoor radon was measured at 25 sampling stations using a radon detector model DOSEman PRO. The sampling was conducted for 8 h to represent daily working hours. A correlation of the radon concentration was made with the annual inhalation dose of the occupants at the indoor stations...

Context and Objective: This study aims to emphasize the importance of an appropriate CSF examination in patients of suspected CNS disease and the necessity of correlating it with the clinico-radiologic findings which will help in early diagnosis of CNS diseases and guide the further management of the disease. Design: In this 2 year study, 215 CSF samples from patients with clinically suspected diseases of the CNS were studied. The CSF samples were analyzed for gross examination, protein, sugar, adenosine deaminase (ADA) levels, microscopic examination and microbiologic examination...

Introduction: Scoliosis is a lateral spinal deformity of 10 degrees or more, resulting in a C-shaped or S-shaped curve of the spine. Information about adolescent idiopathic scoliosis (AIS) prevalence rate is important not only for paediatric health care planning strategy but also for parent's awareness. This study aims to find the suitable inclination cut-off angle and the prevalence rate of AIS in Surabaya, Indonesia. Materials and Methods: This is a descriptive cross-sectional study conducted in 2010. We performed stratified random sampling of 784 Elementary and Junior High School students in Surabaya between 9-16 years of age...

BACKGROUND: and Purpose: The surgical Simpson Grade, introduced in 1957 is the standard measure for meningioma resection and prediction of recurrences. We used an MR-based grading system for the radiological extent of resection, and assessed agreement of the extent of resection between the surgical Simpson Grade and the MR-based scale. MATERIALS AND METHODS: Patients were prospectively included during a two-year period. Immediately after surgery the surgeon determined the Simpson Grade...

OBJECTIVE: The role of ventriculomegaly and its interplay between various dementia entities and their pathogenesis, as well as its correlation to the levels of CSF protein markers, remains to be elucidated. Evans index (EI) is a well-established radiological marker in the diagnosis of idiopathic Normal Pressure Hydrocephalus (iNPH), assessing ventricular enlargement. However, there are no previous studies investigating the correlation between EI, age, beta amyloid (Aβ), tau and phosphorylated-tau (p-tau) proteins in the CSF...

REVIEW
Hiroshi Nishioka, Naoko Inoshita
WHO classification of pituitary adenomas was revised in 2017. The two major and significant changes are discussed. (1) The new classification focuses on adenohypophysial-cell lineage for the designation of adenomas, and thus, assessment of pituitary transcription factors is recommended. Its appropriate use has a complementary role in obtaining an accurate diagnosis, particularly in hormone-negative adenomas. Subclassification of nonfunctioning adenomas was revised accordingly and, consequently, null cell adenomas became quite rare...

BACKGROUND: High-grade gliomas (HGGs) induce both vasogenic edema and extensive infiltration of tumor cells, both of which present with similar appearance on conventional MRI. Using current radiological criteria, differentiation between these tumoral and nontumoral areas within the nonenhancing lesion area remains challenging. PURPOSE: To use radiomics patch-based analysis, based on conventional MRI, for the classification of the nonenhancing lesion area in patients with HGG into tumoral and nontumoral components...

PURPOSE: Use standardized methods to determine how assessment of protective value of radiation-protective garments changes under conditions employing standard beam qualities, scatter-mimicking primary beams, and a modified Hp (10) measurement. METHODS: The shielding properties of radiation-protective garments depend on the spectrum of beam energies striking the garment and the attenuation properties of materials used to construct the garment, including X-ray fluorescence produced by these materials...

Background: Recently, three-dimensional (3D) printing has shown great interest in medicine, and 3D printed models may be rendered as part of the pre-surgical planning process in order to better understand the complexities of an individual's anatomy. The aim of this study is to investigate the feasibility of utilising 3D printed liver models as clinical tools in pre-operative planning for resectable hepatocellular carcinoma (HCC) lesions. Methods: High-resolution contrast-enhanced computed tomography (CT) images were acquired and utilized to generate a patient-specific 3D printed liver model...

INTRODUCTION: Patients with Su Type III fractures based on total knee arthroplasty (TKA) constitute a patient group with problematic treatment and management. Although it has difficulties, open reduction and internal fixation is one of the treatment options. METHOD: A retrospective evaluation was made of 22 patients surgically treated in our clinic with double locking, low contact titanium plate and screw for a Su Type III periprosthetic fracture based on TKA. The patients were evaluated with bone mineral densitometry, postoperative Knee Society Score (KSS), WOMAC and radiological evaluations...

Background/aim: The incidence of adenoid hypertrophy is 2%-3% in children. Adenoidectomy is a commonly performed procedure in children that may cause complications such as early or late bleeding (4%-5%), recurrence of adenoid tissue (10%-20%), and postoperative respiratory problems (27%). Therefore, medical therapy alternatives to adenoidectomy are important and must be tried before surgery. In this study, we investigated the efficacy of mometasone furoate, montelukast, and a combination of these drugs in pediatric patients with adenoid hypertrophy who were scheduled for reduction with medical therapy after not being recommended for surgery...
