ABSTRACT

Background & objectives: Group A streptococcus (GAS) causes a wide array of human diseases. Epidemiological picture of streptococcal infection in India is not complete. Hence, disease burden due to GAS in 5-15 yr old school children in northern India was studied and emm typing of GAS isolates was carried out to help in designing prevention strategies. Methods: A cross-sectional survey was carried out among 4249 school children (5-15 yr) from Raipur Rani Block of Panchkula district in Haryana during 2000-2002; 334 children were followed up fortnightly for one year. Standard clinical and microbiological procedures were used for collection of swabs from throat and skin and confirmation of GAS and its emm types. Results: Of the 4249 children studied, 658 (15.5%) had pharyngitis; 579 of them could be swabbed, of which 2.8 per cent had GAS. From 3591 children without pharyngitis, 3385 who could be swabbed, GAS was found in 1.3 per cent of them. Impetigo was rare (0.7%), but 7.1 per cent (2/28) children had GAS. In the followup study, 17.4 per cent (776/4447 child-contacts) had pharyngitis, 761 could be swabbed and 2.4 per cent had GAS; among those without pharyngitis, 2016 swabs could be taken and GAS was found in 1.3 per cent; whereas only 2.6 per cent (2/75) of skin sores had GAS. Three children had GAS pharyngitis twice during follow up. Fourteen different GAS emm types were found. emm 71, 77 and 81 constituted 69 per cent of the pharyngeal isolates. GAS pharyngitis and impetigo were more common in winters and summers respectively. Interpretation & conclusions: In north India, pharyngitis was more common than impetigo. Most prevalent emm types of GAS in this region differ from those included in M protein-based vaccines.

ABSTRACT

Impetigo is a common contagious superficial skin infection, most frequently seen in children. To determine the clinical and epidemiological features of impetigo patients seen in the dermatology clinic of King Fahd Hospital of the University [KFHU]. This is a retrospective study of impetigo patients seen in the dermatology clinic at KFHU, Al-Khobar, Saudi Arabia, during the period January 1990 to December 2001. Data collected from patients' records included demographic features, clinical features, investigations and treatment. Only patients with positive skin culture were included in the study. The total number of patients included in this study was 65 and constituted 0.08% of all the cases presenting with dermatology problems in that period. Males were affected by impetigo more than the females, giving a ratio of 1.7:1. The majority of the cases occurred in children less than 10 years of age, and the bullous form of impetigo was the predominant type. The sites affected by impetigo were mainly the extremities and the face. The highest number of patients was seen during summer and Staphylococcus was the most common causative agent. The incidence and prevalence of impetigo in Saudi Arabia is unknown and can be best defined by prospective community-based study. The diagnosis and management of impetigo is best achieved by microbiological cultures and sensitivities laboratory investigations

ABSTRACT

In tropical countries pyoderma is a common problem particularly in summer and monsoon. Causative organisms are Staphylococcus aureus, Streptococcus pyogens, Bacillus proteus, pseudomonas and coliform bacilli. Infection of the skin is characterized by discrete thin walled vesicles and bullae which rapidly become pustular then rupture. Impetigo occurs mainly on exposed parts of the body. Lesions occurring on scalp are mostly associated with pediculosis capitis. On rupture of these lesions a thin straw coloured seropurulent discharge is noticed. Sometimes group A beta-haemolyticus infections may follow acute glomerulonephritis. Impetigo occurs most frequently in early childhood. It may simulate different superficial skin conditions like circinate patches of ringworm. It is a common but simple problem, which can be easily cured by topical therapy and if needed systemic antibiotics can be given. Topical corticosteroid ointments should not be used, they worsen the infection

ABSTRACT

Durante los meses de noviembre de 1996 a marzo de 1997, en dos localidades del sur de la provincia de Santa Fe (Roldán y Casilda), se procedió al examen dermatológico de 800 niños sanos, entre 5 y 13 años. La entrevista y el examen físico se realizaron en las escuelas primarias de ambas localidades. El protocolo incluía: datos personales, características fenotípicas del individuo, antecedentes familiares y personales de dermatosis y enfermedades cutáneas detectadas. Todos los niños recibieron tratamiento y fueron citados a un nuevo control. Las dermatosis más frecuentemente detectadas fueron: pediculosis, pitiriasis alba fascie, prurigo, escabiosis, verrugas vulgares, impétigo y dermatoficias. Consideramos que este tipo de detección de patologías de piel es una acción preventiva de salud y que el mejor ámbito para la prevención masiva en salud es la escuela

ABSTRACT

Analiza que el Impétigo es una afección cutánea, producida por estafilococos o estreptococoss, sólos, o asociados entre si. Para diagnosticarlo debe tomarse en cuenta factores epidemiológicos como el hábitat del agente causal, infecciones cutáneas o faringeas previas, grupos de riesgo, hábitat del huésped, clima, factores socio-económicos, etc, además de manifestaciones clínicas d ecada variedad de impétigo, entre ellas, características de la costra entre otras. Es necesario el reconocimiento oportuno de la enfermedad para poder extender un tratamiento adecuado como es la antibióticoterapia y de esta manera evitar complicaciones que pueden afectar el estilo de vida del paciente. En la presente descripción se describe un caso, en el cual el diagnóstico, y su manejo y resulatados muy didáctico...

ABSTRACT

Objetivos: - Determinar la prevalencia de patología dermatológica en la consulta ambulatoria. - Identificar la significación de las diferencias y mensurar la percepción de afección cutánea según nivel socioeconómico y lugar de consulta. Antecedentes: La consulta dermatológica ambulatoria pediátrica es reconocida como frecuente, predominando sólo ciertas patologías específicas. Sólo un 10 por ciento requeriría derivación especializada. Diseño: Se realizó estudio descriptivo de prevalencia basado en muestreo no aleatorio de conveniencia. La población se conformó con los demandantes en las dos últimas semanas de septiembre de 1995 en el CESAC Nº5 y en los consultorios de Bajo y Mediano Riesgo del Hospital Garrahan. Se efectuó la comparación con la población observada en el mismo período en el consultorio de Orientación del Servicio de Dermatología del Hospital Garrahan. Resultados: Para una proporción esperada de 15 por ciento, las observadas fueron: CESAC: 12,9 por ciento (p > 0,05); Hospital: 9,2 por ciento (p < 0,05). Resultó significativa la diferencia entre ambas instituciones (p < 0,05), al igual que los tipos de patología (p < 0,001), no siendo así según nivel socioeconómico (p = 0,09). La percepción de patología dermatológica mostró diferencias significativas según nivel socioeconómico (p < 0,0001). Esto no se dio tomado el Hospital aisladamente (p = 0,85). Conclusiones: Existe alta frecuencia y percepción de patologías dermatológicas, sobre todo en medios socioeconómicos bajos, predominando las de causa infecciosa. No se advierten diferencias según patología entre los consultorios generales y especializados
