Uticaj aeromonas salmonicida na obrastanje i mikrobijalnu koroziju prevlake od legure nikla i bakra na kavezne sisteme u moru

Biofouling acts one of the most serious problems to marine industry and aquaculture development. In the marine environment, surfaces immersed in seawater are colonized by micro-biofoulers such as marine bacteria, algae, and protozoa (Callow and Callow, 2002; Dobretsov et al., 2006). Biofouling of sea cages is a great concern for the salmon growers. When a sea cage is first immersed, there will be a succession of organisms that colonize the cage (Hodson et al., 1997). Bacteria produce an exo-polysaccharide layer (EPS), which act as a protective barrier from the treated surface but also harmful to the lower substratum, in case of the physical degradation or bio-deterioration of the metal surface. This situation is called Microbial corrosion (Yuan and Pehkonen, 2009). In addition, there is a possibility that cage can act as a reservoirs for some disease-causing organisms so one of these bacteria is Aeromonas salmonicida. This bacterium is an aquatic Gram-negative bacterium causing lethal disease furunculosis in salmonid fish. Along with other members of the family Vibrionaceae (V. anguillarum, V. ordalii, A. hydrophila), diseases caused by these organisms can rapidly decimate populations of farmed marine or freshwater fish (Garduna et al., 1994). To reduce the amount of fouling, increase the water quality and decrease the chance of disease occurrence, cage can be coated with antifouling copper alloys and paints (Hodson and Burke, 1994). On the other hand, the tremendous applications of Ni-Cu alloys in different industries, especially in ships where chloride containing waters are always used, making the corrosion processes under the influence of chloride ions understandable and the control of these processes important subject of intensive investigations (Badawy et al., 2005). Therefore this study examines the effects of A. salmonicida in biofouling on Ni-Cu cage coating and its microbial corrosion influence. This study was performed using pure cultures of the A. salmonicida, isolated from water samples. The isolated bacterium was characterized on the basis of 16S rRNA sequences and submitted to NCBI under Accession No. GU907676 (San et al., 2010). The bacterium was cultured then centrifuged and used for bio-corrosion experiments. Electrochemical measurements were carried out in a conventional three-electrode cell. The polarization curves were measured using CompactStat Potentiostat (IviumStat, The Netherlands). Mild steel was used as a working electrode in electrochemical studies. The Ag/AgCl (sat. KCl) electrode (CHI111, CH Instrument, USA) was used as the reference electrode and a platinum wire (CHI115, CH Instrument, USA) was used as counter electrode for all experiments. Ni-Cu alloy was electrodeposited from a nickel-copper bath. The corrosion potential of Ni-Cu electrodes was -0.08 V (vs. Ag/AgCl) but, the corrosion potential of Ni-Cu electrodes in the medium inoculated with the bacterium shifted to cathodic site, -0.63 V (vs. Ag/AgCl) means the increased rate of corrosion. In addition, increase of corrosion current and corrosion current densities with an increase in presence of bacterium means the increased rate of corrosion. Besides, pH values of the medium did not change throughout the experiment (6.8) but after immersion, the pH value decreased to acidic value, 5.5 Furthermore, SEM micrographs show influence of biofouling by bacterium to Ni-Cu alloy. As a consequence, A. salmonicida colonize, strongly adhere and biofouling on alloy surfaces. This situation results in causing the lethal disease in salmon fish and microbial corrosion of cage material

Bilateral Choroidal Detachment Induced by Unilateral Application of a Fixed Combination of Topical Timolol Maleate and Brinzolamide

We describe a 66-year-old man who developed bilateral choroidal detachment that was induced by unilateral topical administration of a fixed combination of 1% brinzolamide and 0.5% timolol maleate the day after an uneventful phacoemulsification surgery and intraocular lens implantation involving his right eye. We believe that the reaction was an idiosyncratic reaction, most likely against brinzolamide. The condition improved rapidly after the cessation of the fixed combination of brinzolamide and timolol maleate and treatment with 1% topical prednisolone acetate every hour and 1% cyclopentolate twice a day bilaterally. Although there are several similar cases involving choroidal detachment after oral acetazolamide and topical dorzolamide treatment mentioned in the literature, the present case is the first case report involving bilateral choroidal detachment after topical treatment with brinzolamide.Â

LIMPRINT study - the Turkish experience

Background: Lymphedema and chronic oedema is a major healthcare problem in both developed and non-developed countries The LIMPRINT study is an international health service based study to determine the prevalence and functional impact in adult populations of member countries of the International Lymphoedema Framework (ILF). Methods: 1051 patients from 8 centers in Turkey were recruited using the LIMPRINT study protocol. Data were collected using the core and module tools which assess the demographic and clinical properties as well as disability and QoL. Results: Most of the Turkish patients were recruited from specialist lymphedema services and were found to be female, housewives and having secondary lymphedema due to cancer treatment. The duration of lymphedema was commonly less than 5 years and most of them had ISL Grade 2 lymphedema. Cellulitis, infection and wounds were uncommon. The majority of patients did not get any treatment or advice before. Most of the patients had impaired QoL and decreased functionality, but psychological support was neglected. Although most had social health security access to Lymphedema centres nevertheless access seemed difficult due to distance and cost. Conclusion: The study has shown the current status and characteristics of lymphedema patients, treatment conditions, the unmet need for the diagnosis and treatment as well as burden of the disease in both patients and families in Turkey. National health policies are needed for the prevention, diagnosis and treatment in Turkey that utilise this informative data

Pediatric Ocular Acne Rosacea: Clinical Features and Long Term Follow-Up of Sixteen Cases

Purpose: To report the clinical characteristics, treatment modalities and long term follow-up of 16 pediatric ocular acne rosacea patients. Methods: The medical records of pediatric ocular acne rosacea patients were reviewed. Results: There were 16 patients with a mean age of 7.7 +/- 5 (1-16) years. The mean follow-up period was 52.8 +/- 52 (3-150) months. Eight patients had skin involvement. The mean duration of delay for diagnosis was 16.2 +/- 5.1 (4-48) months. Nine patients had a delayed diagnosis. Meibomitis, blepharitis, lid telangiectasia, and conjunctival hyperemia were present in all cases. Systemic antibiotics were prescribed in 12 patients. The mean delay in diagnosis was longer in patients with conjunctival/corneal involvement (p = .001) and these patients required longer systemic treatment (p = .001). Complete remission was achieved in 87.5% of cases. Conclusion: Children presenting with a long history of ocular irritation, meibomian gland disease, recurrent chalazia and peripheral corneal infiltrates should alert ophthalmologists to consider the diagnosis of ocular acne rosacea even in the absence of skin changes

Sexual function and Dyadic adjustment in women with urinary incontinence

WOS: 000464441700027PubMed ID: 31086529Objective: This study was planned to evaluate the effects of urinary incontinence (UI) on sexual function (SF) and dyadic adjustment. Methods: The study was conducted with 203 women with urinary incontinence. This study was conducted at Urogynecology Outpatient Clinic of our hospital between September 2017 and February 2018. Data were collected using the Dyadic Adjustment Scale (DAS), and "Female Sexual Function Index (FSFI). Results: The incidence of sexual dysfunction (SD) was higher in the patients who were in advanced age, had a husband older than them, entered menopause, had lower levels of education, had the higher frequency of UI and changed pads more frequently, and these patients had lower DAS scores. Conclusion: It was determined that the majority of the participating women with UI experienced SD and that those with SD had lower DAS scores

Subjective and objective clinical outcomes of a new trifocal toric intraocular lens and effect of femtosecond laser cataract surgery

Purpose: To evaluate the clinical outcomes and quality of life following implantation of PanOptix toric intraocular lens (IOL) and to compare the outcomes following femtosecond laser assisted cataract surgery (FLACS) and standard cataract surgery (SCS). Methods: This comparative retrospective study included 79 eyes of 55 patients underwent cataract or refractive lens exchange surgery between April 2017 and January 2020 in Bayindir Hospital and Kaskaloglu Eye Hospital. Corneal (CA) and refractive astigmatism (RA), uncorrected visual acuities for distant, intermediate, and near (UDVA, UIVA, and UNVA), low contrast distance visual acuity, rotational stability, defocus curves, photopic and mesopic contrast sensitivity (CS), visual function-14 (VF-14) test, presence of dysphotopsia, and need for spectacles were evaluated at postoperative third month. Outcomes were compared between FLACS and SCS group. Results: The mean UDVA, UIVA, and UNVA were 0.05 +/- 0.07, 0.08 +/- 0.08, and 0.06 +/- 0.07 logMAR, respectively. All patients achieved > 0.3 logMAR uncorrected visual acuity for all distances. UDVA was found significantly better in FLACS group (p = 0.03). All eyes had <= 1 D of subjective postoperative RA. Defocus curve had two peaks at 0 and -1.50 D. Spectacle independence was achieved in 88.7% of patients. Photopic and mesopic CS was within normal range in all patients. The mean VF-14 score was 98 +/- 2. The mean IOL axis rotation was 2.1 degrees +/- 2.3 degrees. Only one patient reported seeing disturbing halos. Conclusions: This trifocal toric IOL effectively reduced refractive astigmatism and provided excellent visual outcomes with high spectacle independence, patients' satisfaction, and good rotational stability. FLACS might have an impact on optimal postoperative results
