Disorders of the Immune System and Susceptibility to Various Diseases in Children with Diabetes Mellitus

The article examines the features of emerging disorders of the immune system in children suffering from diabetes mellitus, as well as the susceptibility of such children to various diseases. The authors note that children with diabetes have some disorders of the immune system, which, combined with high glycemia, increase the risk of infections and their severity, and they should be immediately detected and treated. Infections, even typical childhood diseases, significantly interfere with glycemic control. As a result of the infectious process, the level of counter-regulating hormones, cortisol, adrenaline and growth hormone increases, which leads to increased neoglycogenesis, glycogenesis and increased insulin resistance. This increase in insulin resistance requires adjustment of the patient's usual insulin dose, both basal and bolus. There are usually several hours or days before such a need arises, and it may take time to increase the dose, which can lead to hyperglycemia during this period. The presence of an infectious condition, in turn, increases blood glucose levels and increases the risk of decompensation, so pediatricians should be warned against the need to strengthen monitoring and insulin therapy. Patients with diabetes are often not fully vaccinated against various diseases. Vaccines are vital for these patients, significantly reducing the risk of infections and exacerbating the development of the underlying ailment.

Major approaches to antiseptic management for endodontic treatment in the COVID-19 pandemic: a guideline

Introduction: In the COVID-19 pandemic scenario, in addition to the pathogenesis of SARS-CoV-2, microbial coinfection increases the difficulties of diagnosis, treatment, the prognosis of COVID-19, as well as it can worsen comorbidities and affect the risk of the life of patients. COVID-19 has had a profound impact on dentistry. In addition to endodontic treatment, a management protocol was suggested. Objective: To present the importance of effectively performing endodontic asepsis in the context of the COVID-19 pandemic, to elucidate that infection by the SARS-CoV-2 virus can lead to coinfection, worsening the conditions for endodontic treatment. Methods: The research was carried out from July 2021 to August 2021 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, following the Systematic Review-PRISMA rules. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 70 articles were found involving the endodontic treatment and COVID-19. A total of 58 articles were evaluated in full and 39 were included and evaluated in the present study. It was found that ozone has high antimicrobial action. N-acetylcysteine (NAC) has a potent effect against endodontic biofilms. Calcium hydroxide is more effective as a root canal disinfectant in primary teeth than formocresol and camphorphenol. The association of 2% chlorhexidine followed by ozone gas for 24 seconds promoted the complete elimination of Candida albicans and Enterococcus faecalis. Low-intensity laser therapy has the property of oral sterilization, facilitating tissue healing and sterilization. Combining antimicrobial photodynamic therapy with antimicrobial irrigants may provide a synergistic effect. Conclusion: There are effective treatments for the sterilization of endodontic tissues, to avoid as much as possible the coinfection with SARS-CoV-2 and the consequent worsening of the infectious condition, highlighting calcium hydroxide, ozone therapy, and laser therapy.

Prevalence and Antibiotic Resistance Profile of Bacterial Pathogens in Aerobic Vaginitis: A Retrospective Study in Italy

Aerobic vaginitis (AV) is a vaginal infectious condition, characterized by a high inflammatory response and/or signs of epithelial atrophy, a decrease in the amount of Lactobacillus spp. and an increase in enteric origin bacteria. AV, often misdiagnosed, is difficult to treat due to the emerging spread of multi-drug resistant bacterial strains. The present study aimed to define the prevalence of AV, to detect causative bacteria and their antimicrobial resistance pattern. Women 10–95 years old, admitted to San Giovanni di Dio e Ruggi d’Aragona Hospital, Salerno, Italy (in the years 2015–2019) are included in the study. Bacterial identification and antibiotic susceptibility tests were carried out by VITEK® 2. Among 2069 patients, 1176 tested positive for microbial growth. A higher incidence of infection was found in the 55–64 age group. Among the pathogenic strains, 50.4% were Gram-negative, and 49.6% were Gram-positive. Escherichia coli (E. coli) (32.5%) was the most representative strain, followed by Enterococcus faecalis (E. faecalis) (29.4%), Klebsiella pneumoniae (K. pneumoniae) (7.8%) and Enterococcus faecium (E. faecium) (7.7%). E. coli showed high sensitivity to carbapenems and amikacin. K. pneumoniae carbapenems resistance was fluctuating over time. Alarming resistance to vancomycin was not recorded for Enterococci. Both strains were sensitive to teicoplanin, linezolid and tigecycline. Proper diagnosis and an effective therapeutic approach are needed to improve AV management.

Copper Resistance Promotes Fitness of Methicillin-Resistant Staphylococcus aureus during Urinary Tract Infection

Urinary tract infection (UTI) is an extremely common infectious condition affecting people throughout the world. Increasing antibiotic resistance in pathogens causing UTI threatens our ability to continue to treat patients in the clinics.

A literature review of single file NiTi rotary system in endodontics

The most important step in the success of the root canal treatment is the proper cleaning and shaping of the canal system. Cleaning and shaping means the removal of the entire pulpal tissue from the canal, so that there will be no residue left of any vital structure, that may cause any painful or infectious condition for the future. Some times there occurs difficulty in cleaning as well as shaping of the root canal in the posterior tooth or teeth, where the anatomy of the root is some what curved, and there occur difficulty in removing the vital tissue along with difficulty in achieving the accurate working length of the tooth. In this type of situation use of nickel titanium single file system is quite beneficial.

Decrease in All-Cause 30-Day Mortality after Bacteraemia over a 15-Year Period: A Population-Based Cohort Study in Denmark in 2000–2014

Introduction: Bacteraemia is a frequent infectious condition that strongly affects morbidity and mortality. The incidence is increasing worldwide. This study explores all-cause 30-day mortality after bacteraemia in two out of Denmark’s five healthcare regions with approximately 2.4 million inhabitants. Methods: Clinically significant bacteraemia episodes (n = 55,257) were identified from a geographically well-defined background population between 2000 and 2014, drawing on population-based data regarding bacterial species and vital status. All-cause 30-day mortality was assessed in relation to bacteraemia episodes, number of patients with analysed blood cultures and the background population. Results: We observed a decreasing trend of all-cause 30-day mortality between 2000 and 2014, both in relation to the number of bacteraemia episodes and the background population. Mortality decreased from 22.7% of the bacteraemia episodes in 2000 to 17.4% in 2014 (annual IRR [95% CI]: 0.983 [0.979–0.987]). In relation to the background population, there were 41 deaths per 100,000 inhabitants in 2000, decreasing to 39 in 2014 (annual IRR [95% CI]: 0.988 [0.982–0.993]). Numbers of inhabitants, bacteraemia episodes, and analysed persons having BCs increased during the period. Conclusions: All-cause 30-day mortality in patients with bacteraemia decreased significantly over a 15-year period.

Infection and the kidney

Infections has been known to cause various kidney disorders, either as a result of direct infection of the genitourinary tract by a variety of pathological organisms such as viruses, bacteria, parasites, and fungi; as part of the systemic inflammatory response to overwhelming sepsis; due to infection-related immune dysregulation; or as a ‘para-infectious’ condition. The epidemiology of infection-related kidney disorders varies with socio-economic differences, with parasite and mycobacterial infections occurring in areas of low-resource conditions. Urinary tract infections continue to be a common condition in many countries, with an emergence of antimicrobial resistance being a worrying issue. Blood-borne viruses have been reported to cause glomerular and tubulointerstitial lesions, due to either immune dysregulation or a direct effect of the viruses, and are often seen in areas where the infection is endemic. Genetic and racial predisposition has been reported, and an understanding of the treatment options is important as certain drugs have been known to have deleterious effect on the kidneys.

High resolution ultrasound, nerve conduction study, and other non-invasive investigations in leprosy

Leprosy is a chronic infectious condition caused by Mycobacterium leprae and is endemic in many regions of the world. The diagnosis of this condition is usually clinical except in some situations where investigations are necessary to confirm the diagnosis of leprosy or classify its clinical form. Histopathology is the usual modality for conformation of diagnosis. This review focuses mainly on high resolution ultrasound, nerve conduction study, and other non-invasive investigations in leprosy.

Ceftaroline fosamil: clinical experience after 23-month prescription in a tertiary hospital

Objective. To determine the indications, success rate and adverse effects of ceftaroline fosamil treatment in a tertiary hospital. Material and methods. In total, 84 cases from February 2018 to December 2019 were retrospectively analysed. No exclusion criteria were applied. Results. Eighty-four patients, with a median age of 70 years, of which, 6.7% (56) were male, were treated with ceftaroline fosamil for a median of 14 days. Most indications were off-label, including 29 endocarditis (34.5%), 14 bacteraemia (16.6%), 5 Central nervous system (CNS) infections (6%) and 19 osteoarticular infections (22.6%). Staphylococcus aureus was the most frequently isolated microorganism, including 28 methicillin-sensitive S. aureus (MSSA; 33.3%) and 14 methicillin-resistant S. aureus (MRSA; 16.7%), followed by coagulase-negative Staphylococcus (23, 27.4%). The main reason for ceftaroline fosamil prescription was the failure of previous treatment (41.7% of cases). Treatment was successful in 60/84 patients (71.4%) and failed clinically or microbiologically in 14 (16.7%). Eight patients died for a reason not related to the infection and two were found to have a non-infectious condition. Twenty-two of thirty-five (62.8%) patients prescribed ceftaroline because of failure of previous treatment improved, including eight endocarditis and seven bacteraemia. Adverse effects were reported in five patients (5.9%) including neutropenia, thrombocytopenia, transaminases elevation and creatinine elevation; all except one were mild and all resolved after discontinuation of treatment. Conclusions. Ceftaroline fosamil is a well-tolerated cephalosporine, effective against multi- resistant gram-positive and many gram-negative microorganisms. Our experience suggests that it is effective as a rescue or first-line therapy in other indications than those currently approved.
