BACKGROUND: Screening for ovarian cancer (OC) in women at high risk consists of a combination of carbohydrate antigen 125 (CA125) and transvaginal ultrasound, despite their low sensitivity and specificity. This could be improved by the combination of several biomarkers, which has been shown in average risk patients but has not been investigated until now in female BRCA mutation carriers. METHODS: Using a multiplex, bead-based, immunoassay system, we analyzed the concentrations of leptin, prolactin, osteopontin, insulin-like growth factor II, macrophage inhibitory factor, CA125 and human epididymis antigen 4 in 26 healthy wild type women, 26 healthy BRCA1 mutation carriers, 28 wildtype OC patients and 26 OC patients with BRCA1 mutation...

Lower extremity deep vein thrombosis (DVT) is a frequent cause of admission to the emergency departments (ED). Although the gold standard for diagnosis is the Duplex ultrasound examination, the current study used for diagnosis of DVT in the ED by emergency physicians is the point-of-care compression ultrasound (POCUS). To compare the sensitivity and specificity of the two-point and three-point compression ultrasound (2PCUS and 3PCUS respectively) for diagnosis of lower extremity DVT in an ED management. We prospectively recruited outpatients who were admitted to the ED with suspected lower extremity DVT...

- Primary hyperparathyroidism (PHPT) is characterised by elevated serum calcium levels due to elevated levels, or insufficient suppression, of parathyroid hormone (PTH).- The incidence of PHPT has increased in recent years. This is mainly the result of more frequently performed routine measurements of serum calcium, e.g. as part of postmenopausal screening.- The classically described features of PHPT - bones and stones - are not always observed and most patients are asymptomatic.- Diagnosis of PHPT is only established by biochemical testing, not by imaging...

OBJECTIVE: There are different imaging techniques to assess the parotid glands (i.e., sialography, salivary gland scintigraphy) in patients with Sjögren syndrome (SS). However, their use is limited by the invasive character or high cost. Ultrasound (US) is gaining interest by rheumatologists as a complementary diagnostic tool for SS. To date, there is an increasing body of evidence supporting its sensitivity in the assessment of salivary glands in SS. The aim of our study was to analyze the potential role of US as a diagnostic and prognostic tool in SS and to discuss existing evidence to support its application use...

Despite TSH screening in newborns is currently conducted in most developed countries, patients with thyroid ectopy born before the procedure was introduced or those in whom the screening failed to establish diagnosis, might still appear. In the paper we revise the current state of knowledge regarding the clinical presentation, diagnosis and treatment of patients with thyroid ectopy. As an example, we report diagnostic and therapeutic difficulties in our three patients with thyroid ectopy remaining undiagnosed and untreated during early childhood...

OBJECTIVES: Chronic low back pain (CLBP) is the most prevalent of the painful musculoskeletal conditions. CLBP is a heterogeneous condition with many causes and diagnoses, but there are few established therapies with strong evidence of effectiveness (or cost effectiveness). CLBP for which it is not possible to identify any specific cause is often referred to as non-specific chronic LBP (NSCLBP). One type of NSCLBP is continuing and recurrent primarily nociceptive CLBP due to vertebral joint overload subsequent to functional instability of the lumbar spine...
