Impetiginous Cutaneous Leishmaniasis after COVID-19 Infection in a Patient with Poor Cardiac Profile: A Case Report and Literature Review.

Cutaneous leishmaniasis incidence has been rising in the past couple of decades. Standard therapy often includes antileishmanial drugs; however, due to their low safety and toxicity threshold, alternative treatments are being investigated. The association between COVID-19 and cutaneous leishmaniasis remains unclear and exploring this connection may offer crucial insights into the pathophysiology of and treatment strategies for infected patients.

Streptococcal Bacteremia and Toxic Shock Syndrome: A Rare Etiology Requiring Prompt Diagnosis.

Bullous impetigo leading to streptococcal toxic shock syndrome (STSS) immune activation and massive cytokine release is a rare condition. It has a significant mortality rate, which calls for quick diagnosis, early suspicion, and integrated treatment. Herein, we discuss the case of a 66-year-old man who underwent evaluation for leg swelling before quickly going into shock and experiencing respiratory failure, which necessitated invasive mechanical intubation.

Designing a novel chimeric multi-epitope vaccine subunit against through artificial intelligence approach integrating pan-genome analysis, identification, and immunogenicity profiling.

is a newly identified pathogen that causes respiratory tract infections, skin infections, such as cellulitis, abscesses, and impetigo, and currently, there is no licensed vaccine available against it. To develop a vaccine against , a bacterial pan-genome analysis was applied to identify potential vaccine candidates. A total of 4908 core proteins were retrieved and utilized for identifying four proteins, including SG38 Panton-Valentine leukocidin LukS-PV protein, SG62 staphylococcal enterotoxin type A protein, SG39 enterotoxin B protein, and SG43 enterotoxin type C3 protein as potential vaccine candidates.

HLA-II-Dependent Neuroimmune Changes in Group A Streptococcal Necrotizing Fasciitis.

(Group A Streptococcus, GAS) bacteria cause a spectrum of human diseases ranging from self-limiting pharyngitis and mild, uncomplicated skin infections (impetigo, erysipelas, and cellulitis) to highly morbid and rapidly invasive, life-threatening infections such as streptococcal toxic shock syndrome and necrotizing fasciitis (NF). HLA class II allelic polymorphisms are linked with differential outcomes and severity of GAS infections. The dysregulated immune response and peripheral cytokine storm elicited due to invasive GAS infections increase the risk for toxic shock and multiple organ failure in genetically susceptible individuals.

Managing the deteriorating child with suspected group A infection.

Group A Streptococcus bacteria can cause various pyogenic infections such as tonsillitis, pharyngitis, scarlet fever, impetigo, erysipelas, cellulitis and pneumonia. Most group A Streptococcus infections in children are mild and respond positively to treatment with antibiotics. However, some children develop severe infection accompanied by complications such as sepsis and will require urgent treatment, which may include non-invasive or invasive ventilation and the administration of fluids and vasoactive agents.

A STUDY OF SKIN SEPSIS AMONGST ABATTOIR WORKERS IN MONIYA, IBADAN, OYO STATE, NIGERIA.

Background: Skin sepsis is a pyodermal infection caused by Lancefield's group streptococci and . It is characterized by discolored and mottled skin, cellulitis, impetigo and multi-systemic collagen muscularitis and can be transmitted from person to person.

Objective: This study sampled the skin of consented abattoir workers in Moniya Ibadan, for clinical sepsis, with a view to establishing a causal relationship between the infection obtained and the abattoir workers examined.

Culturally supported health promotion to See, Treat, Prevent (SToP) skin infections in Aboriginal children living in the Kimberley region of Western Australia: a qualitative analysis.

Background: While there are many skin infections, reducing the burden of scabies and impetigo for remote living Aboriginal people, particularly children remains challenging. Aboriginal children living in remote communities have experienced the highest reported rate of impetigo in the world and are 15 times more likely to be admitted to hospital with a skin infection compared to non-Aboriginal children. Untreated impetigo can develop into serious disease and may contribute to the development of acute rheumatic fever (ARF) and rheumatic heart disease (RHD).

Persistence of the Staphylococcus aureus epidemic European fusidic acid-resistant impetigo clone (EEFIC) in Belgium.

Objectives: In August 2018, a public health alert was issued in Belgium regarding clusters of impetigo cases caused by the epidemic European fusidic acid-resistant impetigo clone (EEFIC) of Staphylococcus aureus. As a result, the Belgian national reference centre (NRC) was commissioned to update the epidemiology of S. aureus causing community-onset skin and soft tissues infection (CO-SSTI) to assess the proportion of EEFIC among them.

Pustular psoriasis: A distinct aetiopathogenic and clinical entity.

Pustular psoriasis is a distinct subset of psoriasis that presents with involvement of the skin in the form of sterile pustules along with systemic manifestations. Though it has been conventionally grouped under the umbrella of psoriasis, recent research has shed light on its pathogenetic mechanisms associated with the IL-36 pathway, which is distinct from conventional psoriasis. Pustular psoriasis in itself is a heterogeneous entity consisting of various subtypes, including generalised, localised, acute, and chronic forms.

Modeling the potential health impact of prospective Strep A vaccines.

The World Health Organization published the preferred product characteristics for a Group A Streptococcus (Strep A) vaccine in 2018. Based on these parameters for the age of vaccination, vaccine efficacy, duration of protection from vaccine-derived immunity, and vaccination coverage, we developed a static cohort model to estimate the projected health impact of Strep A vaccination at the global, regional, and national levels and by country-income category. We used the model to analyse six strategic scenarios.

The rise and fall of acute rheumatic fever and rheumatic heart disease: a mini review.

Introduction: The incidences of acute rheumatic fever (ARF) and rheumatic heart disease (RHD), which were leading causes of death in children in the 1920s, have decreased substantially. Considering the recent resurgence of scarlet fever and increased incidence of streptococcal pharyngitis in children, an investigation of the current status of ARF and RHD may be worthwhile.

Objective: To summarize the prevalence trends, pathogenic factors, and prevention strategies for ARF and RHD in children.

Methods to Analyze the Contribution of Complement Evasion Factor (CEF) to Streptococcus pyogenes Virulence.

Group A Streptococcus (GAS, Streptococcus pyogenes) is an exclusively human pathogen that causes a range of diseases, including pharyngitis, tonsillitis, impetigo, erysipelas, necrotizing fasciitis, and toxic shock syndrome. Post-streptococcal sequelae include acute rheumatic fever and rheumatic heart disease. The bacterium produces a large arsenal of virulence factors that contribute to host tissue adhesion/colonization, bacterial spread, and host immune evasion.

A Case Report of Leukocytoclastic Vasculitis: Diagnostic Approach and Treatment.

BACKGROUND Leukocytoclastic vasculitis is a small-vessel vasculitis associated with infections, autoimmune disorders, and certain drugs, but it may also be idiopathic. CASE REPORT We report the case of a 37-year-old woman with no significant past medical history who presented with a chief concern of a full-body rash. Before the rash appeared, she had been treated for group A Streptococcus with amoxicillin and prednisone.

The impact of ivermectin, diethylcarbamazine citrate, and albendazole mass drug administration on the prevalence of scabies and soil-transmitted helminths in school-aged children in three municipalities in Timor-Leste: a before-after assessment.

Background: Integrated programmes that use combination mass drug administration (MDA) might improve control of multiple neglected tropical diseases simultaneously. We investigated the impact of Timor-Leste's national ivermectin, diethylcarbamazine citrate, and albendazole MDA, for lymphatic filariasis elimination and soil-transmitted helminth (STH) control, on scabies, impetigo, and STH infections.

Methods: We did a before-after study in six primary schools across three municipalities in Timor-Leste (urban [Dili], semi-urban [Ermera], and rural [Manufahi]) before (April 23 to May 11, 2019) and 18 months after (Nov 9 to Nov 27, 2020) MDA delivery between May 17 and June 1, 2019.

Bullous Impetigo: A Mimicker of Immune-mediated Dermatoses.

The differential diagnosis of vesiculobullous lesions can be intimidating to the primary care provider. While some entities such as bullous impetigo may easily be diagnosed clinically if the patient's demographics as well as the lesion morphology and distribution present classically, atypical presentations may require additional laboratory studies for confirmation. We describe a case of bullous impetigo with characteristics that clinically mimicked two rare immunobullous dermatoses.

Global economic burden per episode for multiple diseases caused by group A Streptococcus.

Considering the lack of existing evidence on economic burden for diseases caused by group A Streptococcus, we estimated the economic burden per episode for selected diseases. Each cost component of direct medical costs (DMCs), direct non-medical costs (DNMCs), and indirect costs (ICs) was separately extrapolated and aggregated to estimate the economic burden per episode by income group as classified by the World Bank. Adjustment factors for DMC and DNMC were generated to overcome related data insufficiencies.

Impetigo herpetiformis: A rare pregnancy-specific dermatosis.

Impetigo herpetiformis (IH) is a pregnancy-specific dermatosis that is currently considered a form of generalised pustular psoriasis and mainly occurs in late pregnancy during the third trimester. IH presents as erythematous patches and pustules and might have systemic involvement. The disease may be associated with severe maternal, fetal, and neonatal complications.

Higher Rates of Hospitalizations among Pediatric Refugees than Local Population Attending the Emergency Department and Longer In-patient Stay.

Background: The global refugee crises have raised concerns among medical communities worldwide; nonetheless, access to healthcare has rarely been studied even though refugees are a medically high-risk group.

Objectives: To compare pediatric department admission rates from the pediatric emergency department (PED) of refugees and Israelis.

Methods: We compared data from refugee and Israeli children admitted to the pediatric department at Wolfson Medical Center in Israel between 2013-2017.
