Dermatitis perianal estreptocócica: estudio clínico-epidemiológico de 95 episodios / Perianal streptococcal dermatitis: clinical and epidemiological study of 95 episodes

INTRODUCCIÓN Y OBJETIVOS: analizar las características clínico-epidemiológicas de la dermatitis perianal por estreptococo betahemolítico del grupo A (SBHGA). MATERIAL Y MÉTODOS: serie de casos con recogida prospectiva de datos durante un periodo de ocho años en una consulta de Pediatría. RESULTADOS: se diagnosticaron 95 episodios (1/298 consultas) en 76 niños (varones/mujeres: 1,6/1). Edad media 4,5 años. Padecieron más de un episodio 13 pacientes con un total de 19 episodios sucesivos: 10 de ellos en un periodo inferior a 6 meses respecto al anterior (11% del total de episodios). Los motivos de consulta más frecuentes fueron: prurito, sangrado, dolor, estreñimiento y eritema perianal. El tratamiento se realizó por vía tópica en el 70% de los primeros episodios y combinado (tópico y sistémico) en el 68% de los sucesivos. Se constató un fracaso terapéutico inicial en tres episodios. La distribución estacional fue similar a la de faringoamigdalitis y escarlatinas por SBHGA diagnosticadas en el mismo periodo. CONCLUSIONES: cinco motivos de consulta (prurito, sangrado, dolor, estreñimiento y eritema perianal), solos o combinados, estuvieron presentes en el 92% de los episodios. En solo el 17% de los primeros episodios el eritema perianal fue motivo de consulta. Puede ser tenue, sus bordes no siempre son nítidos y en ocasiones asocia lesiones satélites

INTRODUCTION AND OBJECTIVES: to analyse the clinical and epidemiological characteristics of perianal dermatitis cases caused by group A beta-haemolytic streptococcus (GABHS). MATERIAL AND METHODS: prospective case series with collection of data for a period of 8 years in an outpatient paediatrics clinic. RESULTS: there were 95 episodes (1/298 visits) diagnosed in 76 children (predominantly boys, 1.6/1). The mean age was 4.5 years. Thirteen patients had more than one episode, with a total of 19 recurrent episodes, 10 of them within 6 months of the previous episode (11% of the total number of episodes). The most frequent presenting complaints were itching, bleeding, pain, constipation and perianal erythema. Treatment was topical in 70% of the initial episodes, and combination therapy (topical and systemic) was used in 68% of recurrent episodes. The initial treatment failed in 3 cases. The seasonal case distribution was similar to that of pharyngotonsillitis and scarlet fever caused by GABHS in the same time period. CONCLUSIONS: five presenting complaints (itching, bleeding, pain, constipation and perianal erythema), alone or in combination, were present in 92% of the episodes. Perianal erythema was the presenting complaint in only 17% of the first episodes. Erythema can be faint and its borders are not always well demarcated, and may manifest with associated satellite lesions

Características clínico-demográficas de la población del Sur de Gran Canaria con diagnóstico de enterobiasis: valoración de la toma de muestras / Demographic and clinical features of diagnosed individuals of enterobiasis in the southern Gran Canaria: sampling assessment

Introducción. La enterobiasis, causada por Enterobius vermicularis es una de las parasitosis más prevalentes en población infantil, cuyo diagnóstico implica la demostración de los huevos o gusanos mediante el método de Graham. El objetivo del estudio es describir las características clínico-demográficas y microbiológicas de pacientes con sospecha de Enterobiasis en el área Sur de Gran Canaria. Material y métodos. Estudio descriptivo y prospectivo de los resultados de muestras perianales evaluadas mediante el método de Graham por el Servicio de Microbiología del Hospital Universitario Insular de Gran Canaria entre Noviembre de 2014 y Noviembre de 2015. Se ha realizado un análisis descriptivo y de asociación de riesgo de las variables clínicas y demográficas y los resultados del Test de Graham. Resultados. Se obtuvieron 1.128 muestras válidas. En el 11,4% se observaron huevos de E. vermicularis; el 88,4% de las muestras positivas en menores de 14 años y el 53,5% en género masculino. Dolor abdominal (18,6%), prurito anal (11,6%), eosinofilia (8,5%) y parasitosis intestinal (7,8%) fueron los motivos de solicitud en las muestras positivas. Predomino elevado sin diagnóstico de sospecha o diagnósticos no relacionados con enterobiasis. Conclusiones. La enterobiasis es un motivo de consulta en atención primaria y una patología de interés en Gran Canaria. La calidad de recogida de muestras y el diagnóstico de sospecha es necesaria para realizar un buen análisis microbiológico (AU)

Introduction. Enterobius vermicularis, also known as pinworn, is the responsible agent for Human Enterobiasis. It is one of the most prevalent, but underrated, parasitic disease in children population. Diagnosis involves demonstration of either eggs or adult worms by Graham test. The aim of this study is to describe the clinical, demographic and microbiological features of patients with suspected diagnosis of Enterobiasis in southern Gran Canaria. Material and methods. Descriptive and prospective study of perianal samples evaluated by Graham test in the Microbiology Department of `Insular de Gran Canaria´ University Hospital between November 2014 and November 2015. Descriptive analysis to evaluate the correlation between clinical and demographic variables and the results of Graham test microbiological observation. Results. 1,128 samples were analyzed. E. vermicularis was found in 11.4% of the samples. Among the positives samples, 88.4% belonged to children under 14 years, and 53.5% were male. Abdominal pain (18.6%), anal itching (11.6%), eosinophilia (8.5%) and intestinal parasitosis suspicion (7.8%) were the reasons of parasitological investigation request in positive samples. Nevertheless, a high proportion of the requests was not founded in a suspicious diagnosis or was unrelated to Enterobiasis. Conclusions. Enterobiasis is a common disease in primary health care and is of great importance in Gran Canaria. Quality in sample collection as well as diagnosis suspicious information are necessary for a good microbiological analysis (AU)

Perianal streptococcal dermatitis in adults: its association with pruritic anorectal diseases is mainly caused by group B Streptococci.

AIM: Although perianal streptococcal dermatitis (PSD) is well known in children, it has only rarely been documented in adults. The incidence and necessity for treatment may be underestimated. We have retrospectively identified adult patients with perianal streptococcal dermatitis. METHOD: Patients with streptococcal anal dermatitis were identified from a prospective office database. Treatment was with oral antibiotics according to the organism sensitivity. Additional concomitant anorectal disease was treated according to standard guidelines. Patients were compared with a control group, without eczema or erythema, for the presence of ß-haemolysing Streptococci on perianal swab. Demographic and microbiological data were assessed and compared between and within treatment and control groups. RESULTS: Fifty-three (22 female) patients older than 20 (mean = 49) years of age were diagnosed with perianal streptococcal dermatitis between 2005 and 2009. In most cases group B ß-haemolytic Streptococci were found. Fifty patients received antibiotics for 14 days. In 28 of 33 patients who had a post-treatment swab, the result was negative. Five patients showed Streptococci of different groups in the post-treatment swab. Of the 50 patients, 21 (42%) had no further anorectal complaint and 29 (58%) required continuing treatment for another anorectal condition. In the control group ß-haemolysing Streptococcus was found in 34%. Men over 60 years of age more often required no further anorectal treatment compared with women (P < 0.05). CONCLUSION: Perianal streptococcal dermatitis occurs in adult patients more often than reported. It is mainly caused by group B ß-haemolysing Streptococcus. Its diagnosis is important because it can cause serious systemic infections, especially in the elderly and in newborns. Antibiotics resolve the condition in a high proportion of patients.

Perianal streptococcal dermatitis: an important differential diagnosis in pediatric patients.

Perianal streptococcal dermatitis is an infectious disease that predominantly affects younger children and is mostly caused by Group A beta-hemolytic streptococci. Although patients are mostly seen primarily by their pediatrician or family physician, the diagnosis is not infrequently established just after referral to a dermatologist or colorectal surgeon. We report a case series of 124 children, aged 14 years or younger, who were seen at our office for anorectal complaints between February 2003 and September 2006. Twenty-one of 124 patients (16 percent) were diagnosed with perianal streptococcal dermatitis on the basis of a positive perianal swab by microbiologic analysis. Perianal streptococcal dermatitis was the most frequent infectious disease in that age group in our practice. Sixteen (of 21, 76 percent) patients were male, and the mean age was 6.3 years. One course of systemic antibiotic treatment augmented by additional local antiseptic ointment in selected cases cured all patients within 10 to 14 days. One patient presented with a new perianal streptococcal dermatitis episode five months after treatment and was successfully retreated with an oral antibiotic. With this report, we wish to alert the colorectal community of the diagnosis because it may be underdiagnosed in our practices and thereby lead to prolonged discomfort, protracted disease, and potentially harmful sequelae for these typically very young patients.

INTRODUCTION: Perianal dermatitis due to group A beta-hemolytic streptococcus is a rare diagnosis in pediatrics. Clinical manifestations include erythema, edema, and perianal pruritus associated with vulvovaginitis or balanitis, painful defecation, constipation, anal fissures, purulent discharge, and/or rectal bleeding. MATERIAL AND METHODS: A descriptive, observational, prospective study was conducted between May, 2004 and April, 2005. In children presenting to the emergency room with erythema, edema, and perianal pruritus, a rapid streptococcal antigen test and bacterial cultures of their perianal secretions were obtained. Patients with a positive result in the rapid test were treated with oral phenoxymethylpenicillin (40-50 mg/kg/day) for 10 days, after which clinical and bacteriological evaluations were conducted. RESULTS: Of the 24 patients presenting with erythema, edema, and perianal pruritus, 19 patients (12 boys and 7 girls), aged between 6 months and 4 years (median age: 30 months), tested positive for group A beta-hemolytic streptococcus. Nine patients also presented with constipation, 5 with anal fissures, 4 with rectal bleeding, 2 with vulvovaginitis, and 1 with streptococcal pharyngoamygdalitis. Outcome was favorable in 85 % of the patients, and perianal isolation of group A beta-hemolytic streptococcus was negative after treatment in 95 %. CONCLUSIONS: In patients presenting with erythema, edema, and perianal pruritus, perianal streptococcal dermatitis should be ruled out. The rapid test for streptococcal antigen detection is a quick and reliable method for this diagnosis. The antibiotic of choice is oral penicillin.

Aislamiento de estreptococo betahemolítico del grupo A en niños con dermatitis perianal / Isolation of group a Beta-hemolytic Streptococcusin children with perianal dermatitis

Introducción: La dermatitis perianal causada por estreptococo betahemolítico del grupo A (SBHGA) es un diagnóstico poco frecuente en pediatría. Clínicamente cursa con eritema, edema y prurito perianal, y puede asociar vulvovaginitis o balanitis, dolor a la defecación, estreñimiento, fisuras perianales, secreción purulenta y/o rectorragia. Material y método: Estudio descriptivo, observacional y prospectivo realizado entre los meses de mayo de 2004 y abril de 2005. En los niños que acudieron a urgencias por eritema, edema y/o prurito perianal se realizó una prueba rápida de detección de antígeno estreptocócico y un cultivo bacteriano de secreciones perianales. Aquellos casos con determinación rápida positiva fueron tratados con fenoximetilpenicilina oral (40-50 mg/kg/día) durante 10 días, y al finalizar el tratamiento se efectuó un control clínico y bacteriológico del paciente. Resultados: De los 24 casos analizados que acudieron por eritema, edema y/o prurito perianal, un total de 19 pacientes (12 niños y 7 niñas) con edades comprendidas entre los 6 meses y los 4 años (media: 30 meses) presentaron determinación positiva para SBHGA. Un total de 9 casos asociaban estreñimiento, cinco fisuras perianales, cuatro rectorragia, dos vulvovaginitis y uno faringoamigdalitis estreptocócica. El 85 % de los pacientes evolucionaron favorablemente, y tras el tratamiento se negativizó el aislamiento perianal de SBHGA en el 90 % de los casos. Conclusiones: En aquellos pacientes que presenten eritema, edema y/o prurito perianal se ha de descartar dermatitis perianal estreptocócica. La prueba rápida de detección de antígeno estreptocócico es un método rápido y fiable para su diagnóstico. El tratamiento antibiótico de elección es la penicilina oral

The fecal microflora in pruritus ani.

Pruritus ani is a common condition in which there is a tendency for liquids to leak from the anal canal, resulting in perianal soiling. In order to ascertain if an abnormal fecal flora contributes to the irritant effects of fecal material, qualitative and quantitative measurement of the fecal microflora was performed in 20 patients with pruritus ani and 20 matched controls. No differences were found between the two groups. This study has failed to provide evidence for a microbiologic basis for pruritus ani.

The mycotic flora in proctological patients with and without pruritus ani.

The perianal mycotic flora was studied in proctological patients with and without pruritus ani, as well as in control subjects. Four groups of patients underwent perianal mycoculture. In Group 1, 53 patients with anal pruritus were treated for benign anorectal disease. In Group 2, 24 patients with no underlying disease presented with anal pruritus. Both of these groups underwent concomitant chemical and parasitical examination of the faeces and an oral glucose tolerance test. In Group 3, 50 patients without pruritus ani at present or in the past were treated for benign anorectal diseases. In Group 4, 47 surgical patients without pruritus ani were treated for benign (9) and malignant (38) non-proctological diseases. In Group 1 the mycoculture was positive in 24/53 patients (Candida albicans 14, dermatophytes 10). In Group 2 fungal infections were seen in 16/24 patients (C. albicans 7, dermatophytes 9). No parasites or diabetes were found in either group. In Group 3 C. albicans was isolated in 14/50 patients. In Group 4 C. albicans was found in 11/47 cases (2 in benign, 9 in malignant diseases). Infection by C. albicans was observed in all groups studied, independent of the presence of disease or anal pruritus. The presence of dermatophytes was always associated with pruritus ani.
