Managing the deteriorating child with suspected group A Streptococcus 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. In some instances, for example if there are no beds available in the paediatric intensive care unit, these interventions may be undertaken in a ward setting. This article gives an overview of group A Streptococcus infection, including two rare but severe complications, streptococcal toxic shock syndrome and necrotising fasciitis. It uses a fictionalised case study to examine the management of the deteriorating child with suspected group A Streptococcus infection, including respiratory support, haemodynamic support and symptom management.

Streptococcal pharyngitis in a Child, Complicated with a Necrotizing Myositis: Diagnosis, Management and Follow-Up.

BACKGROUND Group A streptococcus is a common cause of pharyngitis and can also cause a wide variety of invasive infections, including necrotizing soft-tissue infections. The presented case is one of the rare occurrences of necrotizing soft-tissue infection as a consequence of hematogenous spread and is the first described pediatric case of streptococcal myositis that was clearly preceded by pharyngitis. CASE REPORT A 2.5-year-old boy, previously healthy, fell ill 3 days before admission with high-grade fever, diffuse erythematous truncal rash and, later, with pain in the left lower leg. The next day, scarlet fever was diagnosed, and he was started on oral penicillin V. In the following 2 days, the fever and pain in the leg did not subside; edema and redness of the left shin appeared. On admission, he was febrile and had tachycardia, and the mouth examination was consistent with bacterial pharyngitis. The left shin was grossly edematous, with diffuse bluish skin discoloration. Empiric antibiotic treatment with benzylpenicillin and clindamycin was started. An ultrasound scan of the left shin revealed extensive myonecrosis. Urgent fasciotomy was done, and necrotic muscles were surgically excised. CONCLUSIONS Streptococcal necrotizing myositis is exceedingly rare. Due to potentially life-threatening complications and a need for urgent surgical intervention, clinicians must have a low threshold of suspicion, even in atypical pathogenesis and presentation.

Recrudescence of Scarlet Fever and Its Implications for Dental Professionals.

A significant increase in the incidence of scarlet fever, mainly in Europe, has been noted during the COVID-19 postpandemic period. Scarlet fever is caused by a pyrogenic exotoxin-producing streptococcus-Streptococcus pyogenes-responsible for more than 500,000 deaths annually worldwide. Superantigens (SAgs) secreted by this Group A streptococcus (GAS) usually overstimulate the human immune system, causing an amplified hypersensitivity reaction leading to initial symptoms such as sore throat, high fever, and a sandpaper-like skin rash. There could be concurrent oral manifestations known as "strawberry tongue" or "raspberry tongue," which may be first noted by oral health professionals. The early diagnosis and treatment of this disease is critical to obviate the development of local and systemic sequelae such as acute rheumatic fever, endocarditis, and glomerulonephritis. Antibiotics should be prescribed early to mitigate its duration, sequelae, and community spread. Dental practitioners should be aware of the early symptoms of scarlet fever for infection detection, emergency patient management, and appropriate referral. This concise review outlines the prevalence, pathogenicity, oral and systemic manifestations, as well as the dental implications of scarlet fever.

Miliaria Scarlatinosa, A Peculiar and Rare Form of Scarlet Fever - A Case Report.

Scarlet fever typically presents with distinctive erythematous papular rash following pharyngitis. Atypical forms may develop, making the diagnosis difficult. We present the case of a girl with fever, and unusual vesicular skin eruption (miliaria scarlatinosa) preceded by a skin infection, without mucosal changes. Leukocyte count, C-reactive protein, and antistreptolysin O-titer were elevated. Bacteriological swabs of the skin injury revealed Streptococcus pyogenes. Histopathology was compatible with scarlet fever exanthema. Intramuscular penicillin and topical wound care induced complete remission. It is of great importance to be aware of uncommon clinical presentations of scarlet fever in order to establish a timely diagnosis and prevent potential complications.

[A toddler with a rare complication of scarlet fever]. / Een peuter met een zeldzame complicatie van roodvonk.

BACKGROUND: Haemolytic group A streptococci (GAS) are the most common bacterial cause of infection in the Netherlands. These bacteria can cause many different non-invasive infections, including scarlet fever. CASE DESCRIPTION: A two-year-old girl presented with fever, tachycardia, exanthema and swelling in the neck. On suspicion of scarlet fever with neck phlegmon we treated her with antibiotics and supportive therapy. Blood and throat cultures revealed growth of haemolytic GAS. Lab tests revealed mild hyperthyroidism and neck ultrasound revealed an inhomogeneous appearance of the thyroid. We diagnosed her with 'infectious thyroiditis', a rare complication of infection with haemolytic GAS. A fistula from the pyriform sinus could not be demonstrated. CONCLUSION: Although GAS infections are common, complications such as thyroiditis are rare. When a paediatric patient is diagnosed with infectious thyroiditis, a fistula from the pyriform sinus should be considered. Patients with such a congenital malformation have an increased risk of recurrent infectious thyroiditis and thyroid abscess formation.

Scarlet fever associated with hepatitis in pediatrics. A case report. / Scarlet fever associated with hepatitis in pediatrics. A case report.

INTRODUCTION: Scarlet fever is a common illness in pediatrics caused by group A beta-hemolytic strep tococcus (GABHS), which usually occurs after an episode of pharyngitis, and has an overall excellent prognosis. Hepatitis secondary to scarlet fever is a rare complication described in adults and even less frequently in children. Our objective was to describe a case of hepatitis secondary to scarlet fever in a pediatric patient. CLINICAL CASE: A 12-year-old male with scarlet fever presented with a 4-day history of jaundice, dark urine, and decreased appetite. Laboratory tests revealed elevated liver enzy mes and total and direct bilirubin levels, and negative studies for hepatitis A, B and C, Epstein Barr virus, parvovirus B19, adenovirus, cytomegalovirus, human herpes virus-6, and herpes simplex virus 1 and 2. Abdominal ultrasound examination was normal. DISCUSSION: The pathogenesis of scarlet fever associated hepatitis remains unclear. Streptococcal pyrogenic exotoxin mediated cellular injury via cytokine production has been proposed as a possible mechanism of hepatotoxicity in GABHS infections. CONCLUSION: Hepatitis secondary to scarlet fever remains a rare but benign entity, with complete recovery expected over weeks to months.

Scarlet fever associated with hepatitis in pediatrics: a case report / Hepatitis asociada a escarlatina en pediatría: reporte de caso

INTRODUCCIÓN: La escarlatina es una enfermedad común en Pediatría, causada por Estreptococo beta hemolítico grupo A (SBHGA), la cual generalmente se presenta después de un episodio de faringitis, y con excelente pronóstico general. La hepatitis secundaria a escarlatina es una complicación, descrita muy rara vez en niños. Nuestro objetivo fue reportar la ocurrencia de hepatitis secundaria a escarlati na en un paciente pediátrico. CASO CLÍNICO: Varón de 12 años cursando escarlatina, quien se presentó con una historia de 4 días de ictericia, coluria y disminución del apetito. Los exámenes de laboratorio revelaron elevación de las transaminasas y de los niveles de bilirrubina total y directa, y estudios vira les negativos para Hepatitis A, B y C, Virus de Epstein Barr, Parvovirus B19, Citomegalovirus, Virus Herpes 6 y Herpes simplex 1 y 2. Ecografía abdominal fue normal. DISCUSIÓN: La hepatitis es una complicación inhabitual de la escarlatina, cuya patogénesis aún no está clara. La producción de citoquinas a través del daño celular mediado por la exotoxina pirógena estreptocócica, se ha propuesto como un posible mecanismo de hepatotoxicidad en infecciones por SBHGA. CONCLUSIÓN: La hepati tis asociada a escarlatina continúa siendo una entidad rara, pero de curso benigno, con recuperación plena en semanas a meses.

Into Darkness and Silence: What Caused Helen Keller's Deafblindness?

In 1882, at 19 months of age, Helen Keller developed a febrile illness that left her both deaf and blind. Historical biographies attribute the illness to rubella, scarlet fever, encephalitis, or meningitis. This analysis of her illness suggests she likely had bacterial meningitis, caused by Neisseria meningitidis or possibly Haemophilus influenzae.

[An rare complication of scarlet fever : invasive group A streptococcal infection with streptococcal toxic shock syndrome]. / Infection invasive à Streptocoque du groupe A dans le décours d'une scarlatine.

Invasive Group A Streptococcus infections and streptococcal toxic shock syndrome are rare complications of common diseases in children such as scarlet fever or impetigo. These invasive diseases are particulary challenging because of their rapid progression and the lack of predisposing factors in most cases. Prompt diagnosis and treatment are mandatory to reduce the mortality associated with these severe diseases. We report the case of an 8- year-old girl who developped an invasive group A streptococcal disease with osteomyelitis and streptococcal toxic shock syndrome in the course of a classical scarlet fever.

Les infections invasives à Streptocoque du groupe A et le syndrome de choc toxique streptococcique sont des affections rares qui peuvent compliquer des infections communes de l'enfant telles que la scarlatine ou l'impetigo. La progression rapide de ces formes invasives et leur survenue, dans la majorité des cas, chez des enfants sans facteur de risque identifiable, les rend particulièrement redoutables. Un diagnostic et un traitement agressif précoces sont essentiels pour réduire la mortalité associée à ces affections graves. Nous rapportons le cas d'une enfant de 8 ans ayant présenté, dans le décours d'une scarlatine, une infection invasive à Streptocoque du groupe A avec ostéomyélite et syndrome de choc toxique streptococcique.

Concurrent peritonsillar abscess and poststreptococcal reactive arthritis complicating acute streptococcal tonsillitis in a young healthy adult: a case report.

BACKGROUND: Streptococcus pyogenes is responsible for 5-15% and 20-30% of acute pharyngitis/tonsillitis in adults and children, respectively. It not only causes acute illness but also can give rise to local suppurative complications such as peritonsillar abscess as well as trigger the postinfectious syndromes of glomerulonephritis, acute rheumatic fever and poststreptococcal reactive arthritis. Here, we report a case of a young healthy adult in whom both peritonsillar abscess and poststreptococcal reactive arthritis developed as a complication of acute streptococcal tonsillitis. To the best of our knowledge, such a coincidence of poststreptococcal sequelae has not been reported previously. CASE PRESENTATION: A 32-year-old previously healthy woman was diagnosed with acute tonsillitis by her family doctor and treated empirically with amoxicillin/clavulanic acid (875/125 mg) twice daily for 5 days. Four days after completing antibiotic therapy, peritonsillar abscess of left tonsil developed. Needle aspiration followed by incision and drainage were performed by otolaryngologist at the Emergency Department. Next, the patient was discharged home on a 10-day course of cefuroxime and metronidazole. The symptoms of peritonsillar abscess were subsiding during treatment, however on the last day of antibiotic therapy, swelling and pain of the left ankle appeared. Five days later the patient was consulted by rheumatologist. Cultures of throat swabs and abscess aspirate collected 2 weeks before revealed the presence of Streptococcus pyogenes. Antistreptolysin O (ASO) titer was evaluated and proved to be 412 IU/ml (normal 0-200 IU/ml). The level of C-reactive protein was 13,0 mg/L (normal <5,0 mg/L). There was no known cardiac involvement. Poststreptococcal reactive arthritis was diagnosed. Left ankle arthralgia persisted for about 5-6 weeks. Six months after the presentation at the Emergency Department, the patient was well, with ASO titer reaching 262 IU/ml. CONCLUSIONS: Clinicians should be aware that appropriate choice of antibiotic, proper dose as well as duration of therapy of acute GAS pharyngitis/tonsillitis are crucial to prevent poststreptococcal sequelae.

Hepatitis, gallbladder hydrops, splenomegaly, and ascites in a child with scarlet fever.

We report a case of scarlet fever associated with hepatitis, gallbladder hydrops, splenomegaly, and ascites in a 15-year-old girl. The girl presented with fever and skin rash. Leukocyte, liver enzyme, and serum C-reactive protein concentrations were elevated. Ultrasonography revealed marked gallbladder wall thickening, diffuse liver parenchymal disease with moderate splenomegaly, and moderate ascites throughout the abdominal and pelvic cavities. Blood cultures for group A ß-hemolytic streptococci were negative. Complete recovery was facilitated with antibiotic treatment.

Scarlet fever epidemic, Hong Kong, 2011.

More than 900 cases of scarlet fever were recorded in Hong Kong during January-July, 2011. Six cases were complicated by toxic shock syndrome, of which 2 were fatal. Pulsed-field gel electrophoresis patterns suggested a multiclonal epidemic; emm12 was the predominant circulating type. We recommend genetic testing of and antimicrobial resistance monitoring for this reportable disease.
