Abstract:

Streptococcus spp. are common causative organisms of endophthalmitis. Analysis of the clinical features, antibiotic susceptibilities, and outcomes of streptococcal endophthalmitis in children and adults may guide future management. Sixty-seven patients (67 eyes) with streptococcal endophthalmitis who were admitted to the Zhongshan Ophthalmic Center between January 2013 and December 2022 were retrospectively reviewed. The mean age was 20.7 ± 21.6 years, and 59.7% were children. Streptococcal infection accounted for 13.9% of culture-proven bacterial endophthalmitis cases; the proportion was high

Behçet's disease is a multisystem inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. The cause of Behçet's disease remains unknown, but epidemiologic findings suggest that an autoimmune process is triggered by an environmental agent in a genetically predisposed individual. An infectious agent could operate through molecular mimicry, and subsequently the disease could be perpetuated by an abnormal immune response to an autoantigen in the absence of ongoing infection.

Acute post-streptococcal glomerulonephritis usually occurs as a complication after a streptococcal infection due to untimely or inadequate antibiotic therapy. The etiology of post-streptococcal glomerulonephritis has been studied rather comprehensively.

Usually, emergence of acute post-streptococcal glomerulonephritis (APSGN) is associated with the so-called GAS-related "nephritogenicity" often judged by appearance and accumulation of antibo

Abstract:

Sore throat is a common complaint, which can be caused by a typical viral pharyngitis, or it can be rooted in a life-threatening disease such as epiglottitis or inflammation of the cellular spaces in the throat and neck. The doctor should take a closer look at a patient with a sore throat, immediately make a differential diagnosis and prescribe adequate treatment, including surgical intervention, if necessary.The article discusses the most common causes of a sore throat, including various types of pharyngitis, paratonsillar abscess, parapharyngeal abscess, retropharyngeal abscess, epiglottitis

Relevance. Caries of hard dental tissues is one of the most common diseases throughout the world. It affects not only the primary teeth of children, but also the permanent teeth of adults, which can lead to serious consequences for human health. In recent years, the dental community has paid special attention to the possible connection between streptococcal infection and the development of caries, and therefore this topic is extremely relevant and requires detailed consideration.

Introduction. It has been hypothesized that pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) etiology results from an abnormal immune response to streptococcal infection. There is evidence that the serotonergic system is involved in both obsessive-compulsive disorder (OCD) physiopathology and immunological processes. In the 5’ promoter region of 5-HTT, gene encoding for the serotonin transporter we can find the 5-HTTLPR polymorphism that has been associated with OCD. Being PANDAS a disorder with OCD symptoms and likely immune abnormalities, 5-HTT

Abstract:

Sore throat is an acutely common health problem both in Russia and around the world as a whole. This is one of the most common reasons adults and children seek primary specialized care. The overuse and misuse of antibiotics, especially for viral infections of the respiratory tract, such as acute and exacerbation of chronic tonsillopharyngitis, greatly increases the risk of developing and spreading antibiotic resistance. Up to 80% of cases of sore throat have a viral etiology of the disease, and even when the infection is bacterial, except for pyogenic streptococcus, the vast majority of cases

Abstract:

Sore throat is a common reason for consulting pediatricians and primary-care physicians. Most cases are of viral origin. Streptococcus pyogenes (Group A Streptococcus, GAS) is the most frequent etiology of bacterial pharyngitis, and may cause more than 30% of pharyngitis cases in paediatric patients and 5–10% of sore throats among adults. Culture remains the microbiological reference method for detection of S. pyogenes. A definitive diagnosis is based on the results of a throat culture. Unfortunately, accurate diagnosis is difficult because (1) the majority of sore throats are viral in origin,

There is always a risk of various wounds, which are the entry gate for infection, in particular Streptococcus pyogenes. Infection often occurs against the background of weakened immunity. Reduced immune properties can result from frequent stress and chronic fatigue due to severe physical and psycho-emotional stress at work. All these factors in combination create favorable conditions for the development of erysipela
