Cavernous hemangioma of the glans penis: Concomitant surgical excision with circumcision in an uncircumcised patient

Hemangiomas are usually superficial, localized, and commonly involve the heador neck, although up to 30% may be seen in the liver. Hemangioma involving theglans penis is extremely rare. A patient with red swelling on the glans penis wasadmitted for circumcision to our clinic. We performed concomitant surgicalexcision together with circumcision, and presented the advantages of surgicaltreatment in such a case

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Enhancement of Photocatalytic Performance with Metal Oxide V2O5 Catalyst Under Different Light Source Illumination

For utilizing of multifunctional catalysts in the photocatalytic systems, V2O5 nanopowders with addition of different metal oxides were prepared by a facile solid-state dispersion method, and then characterized by Brunauer-Emmett-Teller (BET), X-ray powder diffraction, UV-vis diffuse reflectance spectroscopy, scanning electron microscopy, and Fourier transform infrared spectra. Photocatalytic activities of catalysts were evaluated by degradation of bisphenol A (BPA). Degradation rates of BPA and its mineralization effectiveness were analyzed by high performance liquid chromatography (HPLC) and total organic carbon (TOC) measurements. The 50wt% Bi2O3-V2O5 showed a total degradation (100%) of BPA and almost total TOC removal value (98%) in 45min. Results indicated that activity of pure V2O5 could be increased by doping of second metal oxides. Optimum operation conditions were designated by changing the reaction parameters such as light source, presence of peroxide, and catalyst type. Improvements of surface hydroxyl group frequency and the chemical interaction between two metal oxides were presumed to enhanced activity

Selective dehydration of glycerol to acrolein over mesoporous WO3-KIT-6: effects of mesoporosity and acidity

The catalytic performance of tungsten oxide, WO3-KIT-6 in the selective dehydration of glycerol to acrolein was studied. The chemical and structural properties of the catalysts were examined by X-ray diffraction (XRD), nitrogen adsorption-desorption (BET) isotherms, temperature-programmed ammonia (TPD-NH3) desorption, and X-ray photoelectron spectroscopy (XPS), SEM, TGA, Raman and pyridine adsorption FTIR. Catalysts synthesized by the hydrolytic sol-gel (HSG) method showed quantitative conversion of glycerol and acrolein selectivity. The medium-strength surface acidity of the catalyst and mesoporosity played a crucial role in the dehydration of glycerol to acrolein. The maximum stable acrolein selectivity of 55% at 98% glycerol conversion was obtained over 25 wt%W-KIT-6(100) (7.9 nm average pore size) catalyst having the highest concentration of medium-strength acid sites. The effects of mesopore sizes and the selective dehydration of glycerol were elucidated. The catalyst with the largest mesopores diameter displayed higher reactivity, longer lifetime, and improved selectivity

Preliminary characterisation of cornelian cherry (Cornus mas L.) genotypes for their physico-chemical properties

Fruit weight, antioxidant capacity. total anthocyanins, total phenolics. ascorbic acid, soluble solid content (SSC), reducing sugar and acidity of a number of selected cornelian cherry (Cornus mas L.) genotypes of varied pigmentation were investigated. Two methods, namely beta-carotene bleaching and ferric reducing antioxidant power (FRAP) were used to determine total antioxidant capacity, while Folin-Ciocalteu reagent was used to determine total phenols. Fruit weight, SSC and ascorbic acid content of genotypes were 2.09-9.17: 12.53-21.17% and 29-112 mg/100 g, respectively. Antioxidant activity and total phenolic content varied among genotypes and 44-18 genotype had the highest antioxidant capacity using both methods. This genotype also had the highest total phenolic (74.8 mg GAE/g DW) and total anthocyanin (115 mg cyanidin-3-glucoside equivalents /100 g FW) content. There are linear relationships between antioxidant capacities and total phenols. The present study demonstrates the potential of certain cornelian cherry genotypes, notably 44-18, for improvement of nutritional value through germplasm enhancement programmes.

Genetic Relationships Among Some Hawthorn (Crataegus spp.) Species and Genotypes

The genus Crataegus is well distributed in Turkey as a wild plant, with numerous, inherently variable species and genotypes. RAPD markers were used to study 17 hawthorn genotypes belonging to Crataegus monogyna ssp. monogyna Jacq (2 genotypes), C. monogyna ssp. azarella Jacq (1), Crataegus pontica K.Koch (3), Crataegus orientalis var. orientalis Pallas Ex Bieb (3), Crataegus pseudoheterophylla Pojark (1), Crataegus aronia var. dentata Browicz (1), C. aronia var. aronia Browicz (4), and Crateagus x bornmuelleri Zabel (2). The 10 RAPD primers produced 72 polymorphic bands (88% polymorphism). A dendrogram based on Jaccard's index included four major groups and one outgroup according to taxa. The lowest genetic variability was observed within C. aronia var. aronia genotypes. The study demonstrated that RAPD analysis is efficient for genotyping wild-grown hawthorns

Evaluation of Turkish apricot germplasm using SSR markers: Genetic diversity assessment and search for Plum pox virus resistance alleles

Apricot (Prunus armeniaca L.) is an important fruit crop in Turkey, where a rich diversity of apricot cultivars and seedlings is prevalent. The genetic diversity of the Turkish apricot germplasm was investigated. The profiles of 18 simple sequence repeat (SSR) loci of 239 accessions in the genetic source collection of the country as well as those of European and Pakistani accessions were obtained. Eleven SSRs were selected from the apricot molecular linkage group 1 (LGI), and these are located close to the major Plum pox virus (PPV) resistance locus. The remaining seven SSRs represent the other six linkage groups. A high level of genetic diversity (He = 0.74, Ho = 0.63) was observed. Stark Early Orange (SEO)/Harlayne-type resistance alleles of three SSR loci (PGS1.21-240, PGS1.23-161 and PGS1.24-119) were found to be rare in the Turkish accessions (1.7%) but were abundantly found in the Pakistani accessions (41.7%). The genetic clustering analyses, the neighbor-joining tree constructed from the genetic distances of the proportions of shared alleles and the population genetic structure did not distinguish the European accessions from the Turkish accessions. However, 'Harlayne', 'SEO' and the putative resistant apricot accessions were grouped together, indicating a common heritage for the resistant accessions. SSR profiles of the accessions will improve the management of apricot gene banks, and information on the genetic variation in Turkish apricots will assist the international research community.
