PURPOSE: To compare the anatomical and functional results achieved with subretinal fluid drainage (SRFD) and perfluorocarbon liquid (PFCL) use in patients with rhegmatogenous retinal detachment (RRD) treated by primary pars plana vitrectomy (PPV). METHODS: The study included 162 eyes of 162 patients who underwent PPV for RRD, either with PFCL (n = 108) or SRFD (n = 54). The 2 groups were matched in 2:1 ratio for age, gender and lens status. Groups were compared for rates of retinal reattachment, visual improvement, and the occurrence of recurrent RRD and any other postoperative complications...

Aniba canelilla (H.B.K.) Mez is an aromatic plant from the Amazon region whose essential oil has 1-nitro-2-phenylethane (NP) and methyleugenol (ME) as major compounds. Despite of the scientifically proven antifungal and anti-inflammatory activities for these compounds, there is no report up to date about the topical permeation or quantification of NP and ME on skin samples. The aim of this study was the validation of an optimized bioanalytical method by solid-phase microextraction in headspace mode in gas chromatograph with flame ionization detector (HS-SPME-GC-FID) for the determination of NP and ME from the oil in different samples from permeation study, such as porcine ear skin (PES) layers (stratum corneum, epidermis and dermis) and receptor fluid (RF)...

Diuretic resistance is a powerful predictor of adverse outcome in acute heart failure (AHF), irrespectively of underlying glomerular filtration rate. Metrics of diuretic efficacy such as natriuresis, urine output, weight loss, net fluid balance, or fractional sodium excretion, differ in their risk for measurement error, convenience, and biological plausibility, which should be taken into account when interpreting their results. Loop diuretic resistance in AHF has multiple causes including altered drug pharmacokinetics, impaired renal perfusion and effective circulatory volume, neurohumoral activation, post-diuretic sodium retention, the braking phenomenon and functional as well as structural adaptations in the nephron...

Intrapelvic mass formation as a result of particulate wear debris induced osteolysis is a recognised late complication of cementless total hip arthroplasty. Clinical presentation typically involves hip and/or leg pain resulting in functional impairment, and obstructive urinary symptoms developing 3-20 years after surgery. An acute confusional state has never been described in this scenario. We report the case of an 86-year-old gentleman with a diagnosis of dementia brought to our emergency department with an acute confusional state...

One of the potential cardiotoxic action of anti-inflammatory drugs is the occurrence of heart failure (HF), due to their effects on fluid retention and blood pressure. The risk of hospitalization for HF is roughly doubled for both Coxibs, cyclooxygenase-1 (COX-1) and cyclooxygenase- 2 (COX-2) inhibitors, and all the conventional nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs are also associated with a risk of vascular thrombosis, which for NSAIDs is different in relation to their different ability to inhibit COX-1 and COX-2...

Fluid volume overload is common and is associated with adverse outcomes in hemodialysis patients. Practicing physicians individually manage fluid volume balance in their dialysis patients according to blood pressure, interdialytic weight gain, cardiac function, nutritional status, and other comorbidities. However, accurate assessment of fluid volume status remains a concern. Indicators of dry weight target have been explored further with newer concepts and technologies. In general, total body water comprises approximately 50%-60% of adult body weight (range, 45%-75%), and water comprises 73...

Vitamin D3 supplementation is important to prevent and treat hypovitaminosis that is a worldwide public health issue. Most types of supplementation are by oral route or fortification foods. The alternative route must be investigated, as transdermal route, for people with fat malabsorption or other diseases that impair the absorption of vitamin D3 . This study focused on verifying the feasibleness of vitamin D3 skin retention and permeation with the presence of chemical penetration enhancers (soybean lecithin, isopropyl palmitate, propylene glycol, ethoxydiglycol, and cereal alcohol) at different pharmaceutical forms (gel and cream) through a human skin...

Refractory hypertension (RfHTN) is an extreme phenotype of antihypertensive treatment failure defined as lack of blood pressure control with ≥5 medications, including a long-acting thiazide and a mineralocorticoid receptor antagonist. RfHTN is a subgroup of resistant hypertension (RHTN), which is defined as blood pressure >135/85 mm Hg with ≥3 antihypertensive medications, including a diuretic. RHTN is generally attributed to persistent intravascular fluid retention. It is unknown whether alternative mechanisms are operative in RfHTN...

The detection of intrathoracic volume retention could be crucial to the early detection of decompensated heart failure (HF). Transthoracic Bioimpedance (TBI) measurement is an indirect, promising approach to assessing intrathoracic fluid volume. Gel-based adhesive electrodes can produce skin irritation, as the patient needs to place them daily in the same spots. Textile electrodes can reduce skin irritation; however, they inconveniently require wetting before each use and provide poor adherence to the skin...

PEGylated polylysine dendrimers have demonstrated potential as inhalable drug delivery systems that can improve the treatment of lung cancers. Their treatment potential may be enhanced by developing constructs that display prolonged lung retention, together with good systemic absorption, the capacity to passively target lung tumours from the blood and highly selective, yet rapid liberation in the tumour microenvironment. This study sought to characterise how the nature of cathepsin B cleavable peptide linkers, used to conjugate doxorubicin to a PEGylated (PEG570) G4 polylysine dendrimer, affect drug liberation kinetics and intravenous and pulmonary pharmacokinetics in rats...

Heart failure is among the socially significant diseases, involving over 2% of the adult population in the developed countries. Diagnostics of the HF severity remains complicated due to the absence of specific symptoms and objective criteria. Here we present an indicator of the HF severity based on the imaging tissue parameters around the nailfold capillaries. High resolution nailfold video capillaroscopy was performed to determine the perivascular zone (PZ) size around nailfold capillaries, and two-photon tomography with fluorescence lifetime imaging was used to investigate PZ composition...

Arterial hypertension (HT) is one of the most frequently recorded comorbidities among patients under antiangiogenic therapy. Inhibitors of vascular endothelial growth factor (VEGF) and VEGF receptors (VEGFR) are most commonly involved in new onset or exacerbation of pre-existing controlled HT. From the pathophysiology point of view, data support that reduced nitric oxide release and sodium and fluid retention, microvascular rarefaction, elevated vasoconstrictor levels and globular injury might contribute to HT...
