Informative value of McIsaac scale for diagnosis of pediatric scarlatina

Aim. To estimate the statistical indices of informative value of clinical McIsaac scale at the example of scarlatina in children.

Materials and methods. Retrospective cliniсostatistical analysis was carried out on the basis of 30 medical cards of children, hospitalized to children’s unit of Perm Regional Clinical Infectious Hospital in 2017 with diagnosis of scarlatina. The control group consisted of 25 children with moderately severe tonsillopharyngitis.

Results. Clinical peculiar features of scarlatina were studied in 30 children, hospitalized to children’s infectious unit in 2017. Nowadays, scarlatina was revealed to have a typical course with characteristic clinical symptoms, including punctate rash, intoxication with increased temperature up to 38–39, acute tonsillitis, absence of cough in the acute period, moderate regional lymphadenitis. At the hospital stage, there predominate moderately severe forms of this disease. Bacteriological verification of Streptococcus pyogenes (at admittance to the hospital) in the investigated group was 74 %. Typical punctate rash remains the basic clinical symptom of scarlatina. Informative value of McIsaac scale for diagnosis of BHSA-tonsillitis with scarlatina infection was assessed. Specificity of assessment was 92 %.

Conclusions. Clinicodiagnostic McIsaac scale is highly informative for diagnosis of BHSA-tonsillitis among children.
