Background: Central venous catheters (CVCs) are frequently used for monitoring haemodynamic status and rapidly delivering fluid therapy during the peri- and postoperative periods. Indwelling CVCs are typically used 7-14 days postoperatively for additional monitoring and treatment, but patients may develop asymptomatic catheter-related thrombosis, leading to life-threatening pulmonary embolism and death. Early detection helps to avoid such complications. Methods: This prospective observational study investigated the risk factors associated with catheter-related right internal jugular vein thrombosis in patients undergoing chest surgery...

Acoustic Droplet Vaporization (ADV) has the potential to shorten treatment time of high intensity focused ultrasound (HIFU) while minimizing the possible effects of microbubbles along the propagation path. Distribution of the bubbles formed from the droplets during the treatment is the major factor shaping the therapeutic region. A numerical model was proposed to simulate the bubble area evolution during this treatment. Using a linear acoustic equation to describe the ultrasound field, a threshold range was defined that determines the amount of bubbles vaporized in the treated area...

BACKGROUND AND OBJECTIVE: Respiration is known to affect cerebrospinal fluid (CSF) movement. We hypothesised that increased inspiratory resistance would affect the dynamic relationship between blood pressure (BP) changes and subarachnoid space width (SAS) oscillations. METHODS: Experiments were performed in a group of 20 healthy volunteers undergoing controlled intermittent Mueller Manoeuvres (the key characteristic of the procedure is that a studied person is subjected to a controlled, increased inspiratory resistance which results in marked potentiation of the intrathoracic negative pressure)...

A 15-year-old competitive right-handed high school baseball pitcher experienced an acute onset of right elbow pain when throwing. He initially treated it conservatively with rest alone for 3 months, but on return to throwing, he was still experiencing pain. Radiographs revealed that he had a persistent olecranon physis. He proceeded with a trial of low-intensity pulsed ultrasound therapy and attained radiographic evidence of bony union at 7 months postinjury, thus avoiding surgical intervention. He returned to pitching competitively 9 months after injury without elbow pain...

Osteoporosis is a complex multifactorial disorder of gradual bone loss and increased fracture risk. While previous studies have shown the importance of many genetic factors in determining peak bone mass and fragility fractures and in suggesting involvement of fibroblast growth factor-2 (FGF-2) in bone metabolism and bone mass, the relationship of FGF-2 genetic diversity with bone mass/osteoporosis has not yet been revealed. The current study investigated the potential relevance of FGF-2 gene polymorphism in osteoporosis among a Zhuang ethnic Chinese cohort of 623, including 237 normal bone mass controls, 227 osteopenia, and 159 osteoporosis of different ages...

CONTEXT:   Understanding the factors associated with thicker cartilage in a healthy population is important when developing strategies aimed at minimizing the cartilage thinning associated with knee osteoarthritis progression. Thicker articular cartilage is commonly thought to be healthier cartilage, but whether the sagittal-plane biomechanics important to gait are related to cartilage thickness is unknown. OBJECTIVE:   To determine the relationship of a weight-bearing region of the medial femoral condyle's cartilage thickness to sagittal gait biomechanics in healthy individuals...

CASE REPORT: a 63-year old man, followed for a metastatic cardia cancer, develop a pericardial effusion with sign of pre-tamponade. A CT scanner suggests the presence of a gastro- esophageal-pericardial fistula. A surgical drainage brings a purulent fluid, infected by a polymicrobial flora. Despite early antibiotics with vancomycin and piperacillin-tazobactam, the patient dies five days after the drainage. DISCUSSION: purulent pericarditis associated with gastrointestinal neoplasia may be due to sepsis or a proximity invasion ...

CASE REPORT: Six Gilbert's potoroos (Potorous gilbertii) in a captive colony, five of which were closely related, died or were euthanased with severe renal disease. Clinical signs were mostly non-specific. Renal calculi were seen on ultrasound of two affected potoroos and oxalate crystalluria was seen in two of three affected potoroos that had urine samples examined. Necropsies revealed extensive severe renal oxalosis in all affected potoroos. These findings and markedly increased concentrations of glycolate in the urine of the four affected potoroos for which it was measured, confirmed a disorder of oxalate metabolism and suggested a condition similar to primary hyperoxaluria type 1 in humans...

Some studies have not considered body mass as a confounder in analysis of oblique abdominis muscles (OAM) (including the oblique externus [OE] and oblique internus [OI]), which may have led to improper interpretation of results. To assess the differences in the effect of age, gender, and physical activity between normalised for body mass and actual values of the OAM as well as to establish the effect of age, gender, and physical activity on normalised for body mass OAM thicknesses in adolescents. A real-time ultrasound was used to obtain images of the OAM...
