PURPOSE: to study clinical-functional features of remodeling of carotid arteries and its relation to restructuring of the left ventricle (LV) in patients with chronic glomerulonephritis at pre-dialysis stage. MATERIALS AND METHODS: We examined 269 patients (189 men, 80 women) with chronic glomerulonephritis (CGN) aged 17-71 years, at pre-dialysis stages of the disease. We analyzed biochemical parameters of peripheral blood with the determination of daily proteinuria and glomerular filtration rate (GFR)...

We have retrospectively examined a wide range of clinical characteristics, sonographic features, microbiology, and antibiotic regimens in patients with breast abscesses to seek predictive features related to outcome. Because consensus for optimal treatment of breast abscesses has moved toward minimally invasive management using single or repeated needle aspiration (ASP) coupled with adjuvant antibiotics, we assessed whether any factors correlate with the need for repeat procedures by analyzing the number of ASPs and/or surgical incision and drainage (I&D) per abscess...

Partial nephrectomy (PN) is the preferred surgical treatment for T1 renal tumors whenever technically feasible. When properly performed, it allows preservation of nephron mass without compromising oncologic outcomes. This reduces the postoperative risk of renal insufficiency, which translates into better overall survival for the patients. PN can be technically challenging, because it requires the surgeon to complete the tasks of tumor excision, hemostasis and renorrhaphy, all within an ischemic time of preferably below 30 minutes...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a high diagnostic yield in lesions adjacent to the airways. However, complications associated with EBUS-TBNA, such as mediastinitis, have recently been reported. Oral bacteria contamination in punctured lymph nodes can cause severe infections. In the current study, we investigated whether endobronchial intubation using EBUS-TBNA can prevent oral bacterial contamination of punctured lymph nodes...

Skeletal muscle microvascular (capillary) blood flow increases in the post-prandial state or during insulin infusion due to dilation of pre-capillary arterioles to augment glucose disposal. This effect occurs independent of changes in large artery function. However, acute hyperglycemia impairs vascular function, causes insulin to vasoconstrict pre-capillary arterioles, and causes muscle insulin resistance in vivo. We hypothesize that acute hyperglycemia impairs post-prandial muscle microvascular perfusion, without disrupting normal large artery hemodynamics, in healthy humans...

Inflammatory arthritis is characterized by chronic inflammation in the synovium, associated with degradation of cartilage and erosion of juxta-articular bone. The bone loss and joint destruction mediated by aberrant immunological responses resulting in proinflammatory cytokine release and various immune cell activation are known as osteoimmunology. Areas covered: A structured literature search including Medline and PubMed, Cochrane meta-analyses and abstracts of international congresses was performed to review joint damage in inflammatory arthritis in terms of pathogenesis, novel imaging assessment and prevention...

Peripheral regional anesthesia procedures, such as femoral nerve block, are relatively safe procedures in clinical anesthesia. Nevertheless, it may lead to typical, usually transient and rarely even persistent complications. This article aims to highlight key aspects of complications in peripheral regional anesthesia and, in particular, strategies to reduce risk. Moreover, beside general complications, which might potentially occur in any peripheral nerve blockade ("bleeding/infection/nerve damage"), accidental co-blockades of other nerval structures are discussed using the example of the brachial plexus...

Neurofibromatosis type 1 is an autosomal dominant condition characterized by cutaneous and/or plexiform neurofibromas and hyperpigmented café-au-lait spots. It affects multiple endocrine and visceral organs and can be associated with several difficulties such as potential airway (ventilation/intubation) problems, abnormal spinal anatomy, and peripheral neurofibromas. Therefore, anesthesia technique selection becomes more of an issue in terms of avoiding complications and decreasing morbidity and mortality...

Contrast-enhanced ultrasound (CEUS) is an innovative ultrasound technique capable of visualizing both the macro- and microvasculature of tissues. In this prospective pilot study, we evaluated the feasibility of using CEUS to visualize the microvasculature of uterine fibroids and compared CEUS with conventional ultrasound. Four women with fibroids underwent gray-scale ultrasound, sonoelastography and power/color Doppler scans followed by CEUS examination. Analysis of CEUS images revealed initial perfusion of the peripheral rim, that is, a pseudo-capsule, followed by enhancement of the entire lesion through vessels traveling from the exterior to the interior of the fibroid...

BACKGROUND: Peripheral nerve injuries often undergo surgical repair, but poor postoperative functional recovery is frequently observed. CASE DESCRIPTION: We describe four cases of traumatic nerve lesions in whom postoperative recovery was prevented by complications such as detachment of nerve sutures or neuroma growth. To the best of our knowledge no similar cases have been reported in literature so far. It is important an early diagnosis of such condition because it prevents recovery and delays re-intervention, which should be performed before complete muscle denervation and atrophy...
