Cirrhosis is a chronic condition resulting from inflammation and fibrosis of the liver. Patients with cirrhosis may have a myriad of physical examination findings that reflect the severity of the underlying liver disease. Although many signs and symptoms related to cirrhosis are nonspecific, such as abdominal pain, nausea, and malaise, some findings are more specific and point to complications of liver disease. In this article, key physical findings in patients with cirrhosis, including hepatomegaly, splenomegaly, jaundice, ascites, encephalopathy, dilated abdominal wall veins, spider nevi, palmar erythema, and others, are discussed...

Acrocerid flies are endoparasitoids of spiders that are distributed in all ecosystems except deserts and the poles. This group was historically classified into three subfamilies. However, molecular analyses have indicated two new subfamilies. One of these is Cyrtinae Newman, which is made up of two clades: the north, with Palearctic species, and the south, with Chilean species (except for the fossil genus Villalites Hennig). In the southern clade, endemic genera Holops Philippi and Villalus Cole have been poorly described over time by different authors...

BACKGROUND: Rosacea is a common chronic skin condition, but data on its epidemiology and related comorbidities are scarce. OBJECTIVES: To analyze the prevalence and associated cutaneous comorbidities of rosacea in Germany. METHODS: Voluntary dermatological full-body examinations were conducted between 2001 and 2016 in more than 500 German companies by experienced dermatologists and documented electronically. Point-prevalence rates were calculated, and associations were tested with chi-squared tests and logistic regression analysis...

BACKGROUND: Telangiectasias (spider veins) and reticular veins on the lower limbs are very common, increase with age, and have been found in 41% of women. The cause is unknown and the patients may be asymptomatic or can report pain, burning or itching. Treatments include sclerotherapy, laser, intense pulsed light, microphlebectomy and thermoablation, but none is established as preferable. OBJECTIVES: To assess the effects of sclerotherapy, laser therapy, intensive pulsed light, thermocoagulation, and microphlebectomy treatments for telangiectasias and reticular veins...

Purpose: Although acne vulgaris (AV) is a common disease and can persist into adulthood, there are few large-scale epidemiological studies on the prevalence of acne vulgaris in adults. The aim of our study was to characterise the epidemiology and comorbidity of acne vulgaris in working adults in Germany. Patients and Methods: Within the framework of a cross-sectional study, a total of 161,269 employees underwent dermatological whole-body examinations in more than 500 German companies between 2001 and 2016...

Extracellular vesicles (EVs), including exosomes and microvesicles, are membranous vesicles released from nearly all cellular types. They contain various bioactive molecules, and their molecular composition varies depending on their cellular origin. As research into venomous animals has progressed, EVs have been discovered in the venom of snakes and parasitic wasps. Although vesicle secretion in spider venom glands has been observed, these secretory vesicles' origin and biological properties are unknown. In this study, the origin of the EVs from Ornithoctonus hainana venom was observed using transmission electron microscopy (TEM)...

INTRODUCTION: Carotid artery stenting (CAS) has been indicated as an alternative to carotid endarterectomy in high risk patients. Sometimes, an aortic arch can be anatomically unfavourable for CAS. Herein we report our experience in a case of CAS with transcervical approach. PRESENTATION OF CASE: A 77-year-old male was referred to our hospital for severe subtotal occlusion of the left internal carotid artery. He had a past medical history of radiation to the head and neck for laryngeal cancer...

BACKGROUND AND OBJECTIVES: Treatment of vascular lesions is one of the main applications of cutaneous laser technology, while the other is laser hair removal. We present here a vascular laser pumped by a commercial hair removal laser. STUDY DESIGN/MATERIALS AND METHODS: A novel 524 nm vascular laser was designed using a 755 nm hair removal laser as a pumping source. This 524 nm vascular laser was used to treat facial redness and leg telangiectasias in 24 subjects...

Artificial recapitulation of the hierarchy of natural protein fibers is crucial to providing strategies for developing advanced fibrous materials. However, it is challenging due to the complexity of the natural environment. Inspired by the liquid crystalline spinning of spiders, we report the development of natural silk-like hierarchical fibers, with bundles of nanofibrils aligned in their long-axis direction, by self-assembly of crystallized silk fibroin (SF) droplets. The formation of self-assembled SF fibers is a process of coalesced droplets sprouting to form a branched fibrous network, which is similar to the development of capillaries in our body...

BACKGROUND: There is limited data on complications associated with the use of coronary embolic protection devices (EPDs). METHODS: We queried the Manufacturer and User Facility Device Experience database between November 2010 and November 2020 for reports on coronary EPDs: Spider FX (Medtronic, Minneapolis, MN) and Filterwire EZ (Boston Scientific, Natick, MA). RESULTS: We retrieved 119 reports on coronary EPD failure (Spider FX n = 33 and Filterwire EZ n = 86), most of which (78...

OBJECTIVE: This study evaluated the effect of low-energy radiofrequency thermocoagulation added to standard liquid sclerotherapy on clinical outcomes of patients with venous insufficiency. PATIENTS AND METHOD: We included 111 patients with spider veins CEAP/C1 stage. The patients were randomized into sclerotherapy (Group 1) and sclerotherapy + sclerotherapy immediately followed by low energy percutaneous RF thermocoagulation (Group 2) groups and followed up with same protocols prospectively...

Sclerotherapy is the chemical occlusion of vessels using an intravenous injection of a liquid or foamed sclerosing agent that is used in the therapy of blood and lymphatic vessels malformations in the young, and for spider veins, smaller varicose veins, hemorrhoids and hydroceles in adults. This study aimed to assess the effectiveness of mechanosclerotherapy of venous veins with a new device-Flebogrif® -based on an animal model. The experiment was performed on nine Polish Merino sheep weighing 40-50 kilograms...

Spider vein is mostly seen in patients with liver disease, although the underlying problem is sometimes unknown. If spider vein appears on the face, it can affect the self-esteem and self-image of patients. Particularly, females are more vulnerable to these complications. Spider nevi are mostly left untreated since they are considered a cosmetic matter; in case of treatment, the procedure is costly with limited satisfaction. Therefore, this study reports the successful treatment of a spider vein case using a microneedling procedure...

Treatment of skin unaesthetic vascular lesions is still suboptimal. In this article, we present a multicenter study evaluating the efficacy and safety of the sequential 755 nm Alexandrite and 1064 nm ND:YAG lasers for the treatment of acquired and congenital vascular lesions of the skin. A total of 171 patients were included in the study (141 female and 30 male), median age 38, skin type from I to IV. Numbers of patients categorized for treated disease: 22 spider angiomas, 67 facial telangiectasia/spider veins, 58 leg telangiectasia/reticular leg veins, 24 port wine stains (PWS)...

Ogcodes Latreille is the largest genus of Acroceridae. They exhibit a cosmopolitan distribution and parasitize several spider families. Eleven Neotropical species are currently recognized in the genus, with five of them occurring in Chile, though distribution data is limited in this group of rarely collected flies. In this work, we describe a new species, Ogcodes kunkunche sp. nov. Barahona-Segovia from the evergreen forest of Chiloé Island, provide an identification key to the Chilean species of Ogcodes, and include novel distributional data for other species of spider flies (Acrocerinae and Ogcodinae)...

In an attempt to induce experimental varicosity, reverse perforant vein development was initiated in the rat leg by applying a chronic (14 and 32 weeks) partial stricture on the main branch of the deep femoral vein. At surfacing of the incompetent perforantes, typical reticular vein plaques and spider veins were identified by video-microscopy and quantitative histology. Deep vein blood was channeled by them into the saphenous vein system, the extra flow deforming these vessels, causing local dilations and broken course, even undulations of larger branches...

RATIONALE: Colonic telangiectasia, also known as colonic angiodysplasia, refers to arteriovenous malformations that occur in the colon, which are common vascular lesions in the GI tract. PATIENT CONCERNS: We report a patient, who was admitted to our hospital for colonoscopy. DIAGNOSES: Under a microscope, all the segments of the whole colon and the varicose veins showed multiple flaky spider-like telangiectasia changes. The blood vessels were radially distributed and converged in the center...

BACKGROUND AND OBJECTIVE: Varicose veins are the most common complaints of referrals to vascular surgeons. Upon the cause, liquid sclerotherapy could be an efficient solution first in regard to competent main superficial valves. To find the impact of diluted liquid sclerotherapy in varices in patients with no superficial valve refluxes compare to whom wearing only stockings. MATERIALS AND METHODS: Sclerotherapy with 0.3-0.5% liquid form of Sodium Tetradecyl Sulphate (STS) for reticular and spider varicosis, ulcers feeder veins and grade 3-4 sporadic varices were used...

In this study, a novel type of chimeric spider silk proteins (spidroins) NTW1 - 4 CT was blended with poly(L-lactic-co-ε-caprolactone) (PLCL) to obtain nanofibrous scaffolds via electrospinning. Spidroins are composed of a N-terminal module (NT) from major ampullate spidroins, a C-terminal module (CT) from minor ampullate spidroins and 1-4 repeat modules (W) from aciniform spidroins. Physical characteristics and structures of NTW1 - 4 CT/PLCL (25/75, w/w) blend scaffolds were carried out by scanning electron microscope (SEM), water contact angles measurements, Fourier transform infrared (FTIR) spectroscopy and tensile mechanical tests...

BACKGROUND: Chronic venous disease (CVD) is a common vascular disorder with manifestations ranging from asymptomatic spider veins to venous ulcers. Elevated right atrial pressure, otherwise called central venous pressure (CVP), can also result in edema and hyperpigmentation similar to chronic venous insufficiency. Obstructive sleep apnea (OSA) is a known risk factor for elevation of CVP. Prevalence rates of elevated CVP or OSA are unknown in patients presenting with a diagnosis of CVD...
