The growing emergence of antimicrobial resistance represents a global problem that not only influences healthcare systems but also has grave implications for political and economic processes. As the discovery of novel antimicrobial agents is lagging, one of the solutions is innovative therapeutic options that would expand our armamentarium against this hazard. Compounds of interest in many such studies are antimicrobial peptides (AMPs), which actually represent the host’s first line of defense against pathogens and are involved in innate immunity. They have a broad range of antimicrobial activity against Gram-negative and Gram-positive bacteria, fungi, and viruses, with specific mechanisms of action utilized by different AMPs. Coupled with a lower propensity for resistance development, it is becoming clear that AMPs can be seen as emerging and very promising candidates for more pervasive usage in the treatment of infectious diseases. However, their use in quotidian clinical practice is not without challenges. In this review, we aimed to summarize state-of-the-art evidence on the structure and mechanisms of action of AMPs, as well as to provide detailed information on their antimicrobial activity. We also aimed to present contemporary evidence of clinical trials and application of AMPs and highlight their use beyond infectious diseases and potential challenges that may arise with their increasing availability.
The aim of this study was to determine the specificity and sensitivity of the Pelli-Robson and Ishihara diagnostic methods in differing Parkinson's disease from essential tremor compared to DaTSCAN (dopamine transporter scan) findings. The intention was to investigate whether visual dysfunction appears in the early state of Parkinson's disease. Therefore, we included patients with the symptomatology of parkinsonism lasting between 6 and 12 months. The study included 164 patients of which 59 (36.0%) suffered from Parkinson's disease, 51 (31.1%) from essential tremor, and 54 (32.9%) healthy patients which presented the control group. The specificity of Pelli-Robson test in confirming Parkinson's disease was 53% and the sensitivity 81.4%. The specificity of Ishihara test in confirming Parkinson's disease was 88.2%, and sensitivity 55.9%. We found that the colour and contrast dysfunction are present as the earliest symptoms of Parkinson's disease. In this study the Pelli-Robson test is highly sensitive and the Ishihara tables are highly specific in the differential diagnosis between Parkinson's disease and essential tremor, but neither of these methods fulfils the criteria for the validity of a test. We suggest performing both of these methods to evaluate which patients are indicated for DaTSCAN.
IntroductionThe loss of quality of life is the major consequence following a non-fatal road traffic accident (RTA). Previous research regarding quality of life did not include uninjured RTA survivors. The research aim was thus to evaluate the quality of life of the RTA survivors regardless of whether or not they sustained injures, and to identify factors associated with decreased quality of life after the RTA.MethodsA cohort of 200 RTA survivors with and without injuries was followed after experiencing an RTA. The quality of life and mental health outcomes were assessed 1 month following RTA. A vast range of sociodemographic, pre-RTA health-related, RTA related, RTA injury-related, compensation-related factors and mental health outcomes were investigated.ResultsDecreased quality of life following an RTA showed an association with the low socioeconomic status of the RTA victims, poor pre-RTA health, injury-related factors, compensation-related factors and psychological disorders after the RTA.ConclusionsIdentifying predictors of decreased quality of life following an RTA will enable planning interventions targeting the most important factors that influence recovery of RTA victims. Assessing and recording of self-reported quality of life should be a part of the routine protocol in RTA survivors’ health-care.
Legionella pneumophila is defined as a bacterium that can cause severe pneumonia. It is found in the natural environment and in water, and is often found in water tanks. It can be an integral part of biofilms in nature, and the protozoa in which it can live provide it with food and protect it from harmful influences; therefore, it has the ability to move into a sustainable but uncultured state (VBNC). L. pneumophila has been shown to cause infections in dental practices. The most common transmission route is aerosol generated in dental office water systems, which can negatively affect patients and healthcare professionals. The most common way of becoming infected with L. pneumophila in a dental office is through water from dental instruments, and the dental unit. In addition to these bacteria, patients and the dental team may be exposed to other harmful bacteria and viruses. Therefore, it is vital that the dental team regularly maintains and decontaminates the dental unit, and sterilizes all accessories that come with it. In addition, regular water control in dental offices is necessary.
The aim of the study was to evaluate diagnostic tests for keratoconjunctivitis sicca (Schirmer test, tear break-up time (TBUT) test, and corneal staining with fluorescein and lissamine green dye) in patients with blepharospasm. This prospective study included 60 female patients older than 40 with blepharospasm, divided into two groups according to clinical symptoms. For fluorescein test, the surface under the ROC curve was 1.0 with standard error (SE) 0 and 95% confidence interval (95% CI) 0.940-1.0; for Schirmer test, the surface under the ROC curve was 0.817 with SE 0.0555 and 95% CI 0.696-0.905; for lissamine green test, the surface under the ROC curve was 0.813 with SE 0.056 and 95% CI 0.691-0.902; and for TBUT test, the surface under the ROC curve was 0.772 with SE 0.061 and 95% CI 0.645-0.870. According to the results of ROC curve, which determines the sensitivity and specificity of normal values, comparison of diagnostic tests for keratoconjunctivitis sicca used in this study showed that fluorescein test had the best sensitivity and specificity. Schirmer test should be avoided in patients with blepharospasm because its results are influenced by frequent blinking and are not appropriate for study interpretation. Despite the pathologic values of TBUT test (numerically), this test is still acceptable for patients with blepharospasm because its interval takes more time than the interval between two blinks.
The aim of this prospective study was to detect primary open angle glaucoma (POAG) in its early stage in patients at a higher risk of its development, and to identify the risk group with the highest prevalence of POAG. The study was conducted at Department of Ophthalmology, Osijek University Hospital Centre, and included 250 patients divided into five groups, as follows: group 1, patients with diabetes type 1 and type 2; group 2, patients with arterial hypertension (blood pressure >140/90 mm Hg); group 3, patients with positive family history of POAG; group 4, patients with myopia between -3.0 and -8.0 diopters; and group 5, control group including patients aged 40 with no risk factors for POAG development. Study results showed that distribution of glaucoma patients was not equal across the groups. The prevalence of POAG in all patients was 5.6%, whereas in patients with positive family history of POAG it was 14%, which was statistically significantly higher than in patients with diabetes and myopia (4% both), as well as in control group. The difference was greatest in comparison to control group. There was no statistically significant difference in glaucoma incidence between the group of patients with positive family history (14%) and patients with systemic hypertension (6%). The results obtained suggest that of all risk factors analyzed, positive family history of POAG is the most important risk factor for glaucoma development in all risk groups.
SUMMARY – The aim of the study was to determine the role of blepharospasm as a protective factor for the anterior segment of the eye by comparing the degree of blepharospasm and changes of the anterior segment structures. The study included sixty female patients older than forty years with the clinical diagnosis of blepharospasm. They were divided into two groups; the first group consisted of patients with stage I and II of blepharospasm with dominant dry eye symptoms, and the second group consisted of patients with stage III and IV of blepharospasm who required interventional therapy (all patients in this study were treated with botulinum toxin type A). Staining of ocular surface with vital dyes such as fluorescein was used to determine ocular surface defects. Fluorescein stains the corneal epithelial defects, which were statistically less pronounced in the interventional group. In conclusion, comparison of the results between the two groups of patients may implicate that advanced blepharospasm has a protective effect on ocular surface.
Stečeno oštećenje sluha jedno je od najčešćih kroničnih stanja odrasle i starije dobi. Njegov snažan socioekonomski utjecaj razvijene zemlje nastoje umanjiti preventivnim aktivnostima, a jedna od najbitnijih je bolje informiranje javnosti o svim implikacijama, te senzoričke promjene na kvalitetu života. Pritom je najbitnije sustavno informiranje mladih osoba koje su, zbog nedostatka formalnih mehanizama zaštite, pod dodatnim rizikom stjecanja oštećenja sluha zbog čestog izlaganja rekreacijskoj buci. Promjena znanja ove subpopulacije o stečenom oštećenju sluha i njegovim posljedicama ima potencijal promjene njihovih stavova o prevenciji, te u konačnici i mijenjanje rizičnih ponašanja koja pridonose razvoju oštećenja sluha u odrasloj ili starijoj dobi. Zato je važno poznavati početna znanja i stavove mladih osoba o stečenom oštećenju sluha, radi uvida u potrebu aktivnog i sustavnog stručnog rada na njihovoj promjeni, s ciljem podrške prevenciji teškoća slušanja uzrokovanih bukom u ovoj rizičnoj subpopulaciji. U ovom su istraživanju, pomoću ad hoc online upitnika, ispitani stavovi 112 mladih osoba iz čitave Hrvatske o stečenom oštećenju sluha. U skladu s početnom pretpostavkom istraživanja, pokazalo se da su stavovi sudionika o oštećenju sluha uglavnom negativni ili nedovoljno diferencirani, što govori o potrebi sustavnijeg obrazovanja mladih osoba o fenomenu oštećenja sluha, s ciljem prevencije oštećenja sluha stečenog u odrasloj i starijoj dobi.
