We discuss the imaging of several juvenile inflammatory arthropathies including juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile scleroderma, juvenile dermatomyositis, and chronic recurrent multifocal osteomyelitis. Juvenile idiopathic arthritis is the most common autoimmune chronic systemic disease of connective tissue in children. The remaining systemic juvenile connective tissue diseases are rare. However, they require early diagnosis and initiation of treatment to prevent injury, not only to the musculoskeletal system but also to the internal organs, and even death...

Advanced prostate cancer frequently metastasizes to bone and induces a mixed osteoblastic/osteolytic bone response. Standard treatment for metastatic prostate cancer is androgen-deprivation therapy (ADT) that also affects bone biology. Treatment options for patients relapsing after ADT are limited, particularly in cases where castration-resistance does not depend on androgen receptor (AR) activity. Patients with non-AR driven metastases may, however, benefit from therapies targeting the tumor microenvironment...

Advances in medical imaging are invaluable in the care of pediatric patients in the emergent setting. The diagnostic accuracy offered by studies using ionizing radiation, such as plain radiography, computed tomography, and fluoroscopy, are not without inherent risks. This article reviews the evidence supporting the risk of ionizing radiation from medical imaging as well as discusses clinical scenarios in which clinicians play an important role in supporting the judicious use of imaging studies.

Hirschsprungs disease (HD) in adults is extremely rare, only three publications in Czech and Czechoslovak journals making reference to the condition after childhood. We present two cases of adult patients with HD. The first case is a 46-year-old male patient suffering from chronic constipation since childhood and diagnosed with megacolon at the age of 16; however, no further detailed diagnosis was done. At the age of 41, he developed a sigmoid perforation due to fecaloma and underwent urgent rectosigmoid resection and colostomy...

Tuberculosis remains the leading cause of death from an infectious disease worldwide. Early and accurate diagnosis and detection of drug-sensitive and drug-resistant tuberculosis is essential for achieving global tuberculosis control. Despite the introduction of the Xpert MTB/RIF assay as the first-line rapid tuberculosis diagnostic test, the gap between global estimates of incidence and new case notifications is 4·1 million people. More accurate, rapid, and cost-effective screening tests are needed to improve case detection...

OBJECTIVE: Power Doppler ultrasonography (PDUS) and MRI are independently useful to predict structural damage in patients with rheumatoid arthritis (RA). We hypothesize that there is a complementary relationship between these modalities. The aim of this study is therefore to investigate the usefulness of the predictive value of composite assessment of PDUS and contrast-enhanced MRI in radiographic outcomes in patients with RA. METHODS: Twenty patients (17 women and 3 men) with RA on disease-modifying anti-rheumatic drugs (DMARDs) underwent PDUS and MRI of both hands at baseline...

Circumscribed solid nodules are common in pulmonary metastases from sarcoma, but cystic pulmonary metastases from sarcomas are extremely rare. An unusual case of a 33-year-old man presenting with left spontaneous pneumothorax in association with cystic pulmonary metastases from an epithelioid sarcoma in the left forearm was discussed in the present study. The patient underwent wide resection of an epithelioid sarcoma in the left forearm 6 years prior. Periodical computed tomography revealed a gradual increase in the number and size of bilateral multiple cystic pulmonary metastases despite repeated chemotherapy treatment...

BACKGROUND: Basal cell carcinomas (BCC) located in the sun-exposed regions are a serious therapeutic challenge. Therefore early diagnosis and adequate therapy should be of a high priority for every dermatologic surgeon. CASE PRESENTATION: We are presenting a patient with multiple BCCs, located on the area of the scalp, who had been treated several years ago with electrocautery and curettage after histopathological verification. However, the last few years the tumours have advanced, infiltrating firstly the tabula external and a year later the tabula interna of the cranium...

INTRODUCTION: A significant increase of the p-wave of a real-time intracavitary electrocardiography is a reliable and safe method to confirm the central venous catheter tip position close to the atrium. However, conflicting data about the feasibility of electrocardiography exist in patients with atrial fibrillation. METHODS: An observational prospective case-control cohort study was set up to study the feasibility and accuracy of the electrocardiography-controlled central venous catheter tip placement in 13 patients with atrial fibrillation versus 10 patients with sinus rhythm scheduled for elective surgery...

When planned and implemented appropriately, single-unit implant dentistry in the smile zone can be an excellent alternative to attempting to save a failing natural tooth. Historically, implant success has revolved around assessment of osseointegration and the healing of bone around the implant, without much regard for esthetics upon completion. As implant dentistry has evolved, the expectations of both restoring clinicians and patients have expanded to emphasize the esthetic outcome as well as faster treatment with immediate implant placement...

OBJECTIVE: Complex ventral hernia repair is performed increasingly, exacerbated by the obesity epidemic. Imaging can characterise hernia morphology and diagnose recurrence. By systematic review we investigated the extent to which studies employ imaging. METHODS: The PubMed database was searched for studies of ventral hernia repair January 1995 to March 2016. Hernias of all size were eligible. Independent reviewers screened articles and extracted data from selected studies related to study design, use of pre- and post-operative hernia imaging, and the proportion of subjects imaged...

Recognition of axial spondyloarthritis (SpA) remains challenging, as no unique reference standard is available to ascertain diagnosis. Imaging procedures have been used for long in the field, in particular pelvic radiography, to capture structural changes evocative of sacroiliitis, the key feature in SpA. The introduction of MRI of the sacroiliac joints (SIJs) has led to a major shift in recognition of the disorder. MRI has been shown to detect the initial inflammatory processes, in particular osteitis depicted by bone marrow oedema, even in patients having not yet developed structural lesions...

The treatment of soft tissue tumors has maderemarkable progress through advancements in diagnostic imaging and analysis ofsurgical materials. Changes in the treatment of soft tissue tumors are describedfrom my experience since 1977. Prior to the introduction of CT scans, radiography and angiography were the only methods for tumor localization. Wholebody CT, echography, and soft tissue radiography were introduced around 1980,and significant progress was seen in the localization of soft tissue tumors.Although the localization and diagnostic characteristics of tumors becameeasier with the introduction of MRI, radiography and ultrasound still remainedthe primary diagnostic method for soft tissue tumors...

Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients. Therefore, imaging is able to detect tears and describe the risk factors of impingement but cannot confirm subacromial impingement...
