Background: This case highlights the importance of considering hypersensitivity pneumonitis (HP) in the differential diagnosis of interstitial lung disease (ILD) and of obtaining an occupational history so that remediable risk factors may be identified and managed. Aims: To report a case of a chicken sexer with severe rheumatoid arthritis (RA) who developed progressively worsening dyspnoea and restrictive lung disease associated with pulmonary fibrosis. Methods: Clinical investigation included physical examination, occupational history, pulmonary function tests (PFTs), chest imaging and bronchoalveolar lavage (BAL), as well as serological tests including standard IgE bird feather mixture and local IgG precipitin preparation to chicken excrement...

OBJECTIVE: A hypothetical relationship between canine cranial length and the length of the periorbita could be used for intraconal anesthetic volume estimation. STUDY SUBJECTS: Forty-one canine cadaver heads and one macerated dog skull. PROCEDURES: Inion and nasion points were recognized in the macerated skull and used as landmarks for cranial length measure. Thirty cadavers classified as dolichocephalic, mesaticephalic and brachycephalic were distributed in three study groups...

This study presents the numerical analysis of stem fixation in hip surgery using with/without cement methods since the use of cement is still controversial based on the clinical studies in the literature. Many different factors such as stress shielding, aseptic loosening, material properties of the stem, surgeon experiences etc. play an important role in the failure of the stem fixations. The stem fixation methods, cemented and uncemented, were evaluated in terms of mechanical failure aspects using computerized finite element method...

Superior semicircular canal dehiscence (SSCD) describes a pathological aperture at the level of the arcuate eminence. Techniques for quantifying defect size are described with most studies using two-dimensional lengths that underestimate the pathology. The objective of this study is to describe a novel method of measurement that combines manual segmentation of high-resolution computed tomography (HRCT) images of the temporal bone and a morphological skeletonization transform to calculate dehiscence volume. Images were imported into a freely available image segmentation tool: ITK-SNAP (version 3...

Objectives This study aims to evaluate the difference in height between the floors of the posterior ethmoid and sphenoid sinuses with respect to the medial orbital floor (MOF) to confirm this difference as a landmark for identification of the posterior sinuses. It also aims to describe this difference regarding the type of pneumatization of the sphenoid sinus (conchal, presellar, and sellar). Design A cross-sectional study was conducted. Study Center The study was conducted at the Department of Radiology of Hospital de Clínicas de Porto Alegre, a tertiary care university hospital in Southern Brazil...

A 72-year-old male with nausea and heartburn was found to have early pharyngeal squamous cell carcinoma, superficial and advanced esophageal squamous cell carcinoma and early esophageal adenocarcinoma by esophagogastroduodenoscopy. Computerized tomography demonstrated left cardiac lymph node swellings. We prioritized the treatment for esophageal squamous cell carcinoma, as this was the most advanced cancer among the triple primaries. The patient underwent neoadjuvant chemotherapy for esophageal squamous cell carcinoma followed by esophagectomy...

The localization of intracranial electrodes is a fundamental step in the analysis of invasive electroencephalography (EEG) recordings in research and clinical practice. The conclusions reached from the analysis of these recordings rely on the accuracy of electrode localization in relationship to brain anatomy. However, currently available techniques for localizing electrodes from magnetic resonance (MR) and/or computerized tomography (CT) images are time consuming and/or limited to particular electrode types or shapes...

This study aimed to find a better dosimetric parameter in predicting of radiation-induced lung toxicity (RILT) in patients with non-small cell lung cancer (NSCLC) individually: ventilation(V), perfusion (Q) or computerized tomography (CT) based. V/Q single-photon emission computerized tomography (SPECT) was performed within 1 week prior to radiotherapy (RT). All V/Q imaging data was integrated into RT planning system, generating functional parameters based on V/Q SPECT. Fifty-seven NSCLC patients were enrolled in this prospective study...

The purpose of this study was to investigate the consistency of rectal sparing using multiple periodic quality assurance computerized tomography imaging scans (QACT) obtained during the course of proton therapy for patients with prostate cancer treated with a hydrogel spacer. Forty-one low- and intermediate-risk prostate cancer patients treated with image-guided proton therapy with rectal spacer hydrogel were analyzed. To assess the reproducibility of rectal sparing with the hydrogel spacer, three to four QACTs were performed for each patient on day 1 and during weeks 1, 3, and 5 of treatment...

OBJECTIVES: Missed pancreatic injury carries significant morbidity. Computerized tomography (CT) imaging is useful, but may lack sensitivity to identify pancreatic injury. New-generation CT scanners should improve sensitivity, but this has not been studied. A previous study published in 2002 evaluating the sensitivity for identifying pancreatic injury with single-slice CT scanners yielded a 68% correlation between operative and CT findings. We aim to study the accuracy of modern CT for diagnosis and grading of pancreatic injury...

Diagnostic errors in 49 patients with appendicitis handled by the Swedish Health and Social Care Inspectorate were analyzed. Diagnostic errors were more common in young or old patients, and among patients with atypical symptoms. Adjunct diagnostic tools, such as computerized tomography and/or ultrasound examination, also have limitations as regards diagnostic precision, and should therefore not be seen as golden standard. Increased individual knowledge, and not systems factors or safety culture, appears to be a suitable remedy against diagnostic errors...

Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant hereditary familial disorder characterized by development of malignant and benign neoplasms. Differential diagnosis of the adrenal and pancreatic masses are difficult in patients with VHLS. Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and indium-111 somatostatin receptor scintigraphies (In-111 SRS) have important roles in the differential diagnosis of adrenal and pancreatic masses in those patients. In this case report, we present the findings of I-123 MIBG single-photon emission computerized tomography (SPECT/CT) and In-111 SRS SPECT/CT in three members of a family with VHLS...

BACKGROUND/OBJECTIVES: Evaluation of our surveillance program for soft tissue sarcomas (STS) and borderline tumors (BT) for identification of local recurrence and lung metastases the first 2 years postoperatively. METHODS: We retrospectively assessed the medical files of all patients (n = 232) with STS and BT of the extremities and trunk wall who underwent surgery from 2010 to 2013. Two-hundred-and-thirty-two patients were included in the local recurrence study and 116 patients in the lung metastasis study...

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game...

BACKGROUND: SCUBE1 has recently been studied as a diagnostic biomarker for acute coronary syndrome, ischemic stroke, and acute mesenteric ischemia. The aim of this study is to evaluate the value of SCUBE1 and routine parameters used in patients diagnosed with acute appendicitis. METHODS: Of the 150 patients admitted to the emergency department whose initial diagnosis were acute appendicitis (AA), 103 patients were excluded from the study for various reasons. Forty-seven patients with a definitive diagnose of AA and 43 volunteers were enrolled in the study...
