ABSTRACT

El molusco contagioso es una patología viral benigna muy frecuente, exclusiva del ser humano, y causada por un virus no clasificado del grupo de los Poxvirus. Las manifestaciones clínicas de la enfermedad inclu-yen lesiones en la piel, que pueden variar desde una pequeña pápula a un nódulo de mayor tamaño, pre-sentándose en forma solitaria o múltiple, dependien-do del estado inmunitario del paciente y del tiempo de evolución del proceso morboso. El estudio histo-patológico es importante para el diagnóstico, aunque en numerosas ocasiones éste se define clínicamen-te. Además del patrón histológico tradicional, y más frecuente, que exhibe hiperplasia e hipertrofia de la epidermis, se han descripto variantes poco usuales, cuyas características dependen, entre otros factores, de la sobreinfección y de la respuesta inmunitaria del paciente. En este trabajo se describen los rasgos ge-nerales del molusco contagioso y luego se presentan varios casos clínicos, uno de los cuales exhibe ma-nifestación inusual en la semimucosa del labio. Por último, se realizan comentarios referentes a la im-portancia que tiene para el odontólogo conocer esta patología y estar capacitado para detectarla, de modo de evitar sus complicaciones y su diseminación (AU)


Molluscum contagiosum is a very common benign viral pathologythat affects exclusively humans and is caused by an unclassified virus of the Poxvirus family. Clinical manifestations include skin lesions such as papule or nodule, which may range from a small papule to a larger nodule, presenting either solitary or multiple, depending on the immune status of the patient and the time of evolution of the morbid process. Histopathological study is important for the diagnosis, although in numerous occasions it is defined clinically. Classical and more frequent histology pattern exhibits hyperplasia and hypertrophy of the epidermis; however, distinct characteristics may occur depending on factors like superinfection and immune response of patients. This article describes general aspects of molluscum contagiosum and exposes several clinical cases, one of which exhibits an unusual manifestation in the semimucosa of the lip. Finally, comments are made regarding the importance for dentists to learn about the existence of this pathology and be able to recognize it in order to avoid its complications and spread (AU)

ABSTRACT

La infección por molusco contagioso (MC) en adultos se asocia frecuentemente a transmisión sexual y/o inmunodepresión, por ejemplo, por VIH. En este grupo, la manifestación clínica suele ser atípica. A continuación, se presenta el caso de un paciente con diagnóstico de VIH, bajo recuento de CD4 y carga viral elevada que consulta por múltiples MC en genitales, tronco, cara y ojos además de conjuntivitis en ojo derecho. Se mantuvo terapia antirretroviral (TARV) y se indicó tratamiento para conjuntivitis. La infección por MC en pacientes con VIH se asocia a etapas SIDA con un aumento de los casos a menor recuento de linfocitos CD4, generalmente menor a 200 cel/mL. La pobre respuesta inmune celular de estos pacientes explica su comportamiento clínico atípico. Este grupo presenta una mayor mortalidad que el de pacientes seropositivos sin MC, lo que se explica por la mayor inmunosupresión asociada. El diagnóstico es clínico, aunque podría verse entorpecido cuando hay compromiso ocular por la presencia de lesiones atípicas que hacen necesario considerar diversos diagnósticos diferenciales. El tratamiento es controversial y tiende a existir una baja respuesta y recidiva frente a terapias convencionales en pacientes con VIH cuando la inmunosupresión es marcada por el recuento CD4 muy bajo. La TARV pareciera ser la mejor alternativa para su tratamiento, sin embargo, es importante considerar posibles complicaciones asociadas, como la instauración de síndrome de restauración inmunológica una vez iniciada. Esto podría traducirse en lesiones oculares graves cuando existe compromiso en este órgano


Molluscum contagiosum (MC) infection in adults is frequently associated with sexual transmission and / or immunosuppression, for example by HIV. In this group, the clinical manifestation is usually atypical. Herein we present the case of a patient with a diagnosis of HIV, a low CD4 count and a high viral load who consulted for multiple MC in the genitals, trunk, face and eyes, as well as conjunctivitis in the right eye. Antiretrovitral therapy (ART) was maintained and treatment for conjunctivitis was indicated. MC infection in HIV patients is associated with AIDS stages with an increase in cases with a lower CD4 lymphocyte count, generally less than 200 cells / mL. The poor cellular immune response of these patients explains their atypical clinical behavior. This group presents a higher mortality than that of seropositive patients without MC, which is explained by the greater associated immunosuppression. The diagnosis is clinical, although it could be hampered when there is ocular compromise due to the presence of atypical lesions that make it necessary to consider various differential diagnoses. Treatment is controversial and there tends to be a poor response and relapse to conventional therapies in patients with HIV when immunosuppression is marked by a very low CD4 count. ART seems to be the best alternative for its. However, it is important to consider possible associated complications such as the onset of immune restoration syndrome once it has been started. This could translate into serious eye injuries when this organ is compromised

ABSTRACT

Molluscum contagiosum, a viral disease, can cause popular lesion on skin of face, arm, trunk and ano-genital region. Multiple lesions can be observed in immunocompromised hosts. Though the lesions resolves within 2-6 months, in HIV positive patients it may take more time. The mode of transmission, newer diagnostic and therapeutic options have been discussed in this article.

ABSTRACT

Introducción: El Molusco Contagioso (MC) es una enfermedad frecuente de la piel en pediatría. Presenta pápulas perladas con una umbilicación central,independientes, en cualquier lugar del cuerpo. Si bien es de carácter benigno y autolimitado afecta al niño y su familia desde el punto de vista estético y social. Objetivo: Realizar una revisión en forma sistemática de la bibliografía sobre distintos tratamientos para establecer si existe evidencia científica sobre la eficacia y seguridad de los mismos. Material y métodos: Se realiza una búsqueda sistemática utilizando las bases de datos Medline, Lilacs y Cochrane; literatura gris en Google Académico y colaboración de la Biblioteca del Hospital Garrahan. Como estrategia se utilizaron las palabras “molluscum contagiosum” y “treatment”. Se seleccionaron ECAs, Meta-análisis y Revisiones Sistemáticas cualitativas desde 1990 a la actualidad. Se excluyen trabajos en inmunocomprometidos. Para el análisis se utilizaron las guías JAMA. Resultados: Se obtuvieron 15 ECAs y 1 Revisión Sistemática. Se incluyeron solo 8 estudios por reunir los criterios de validez interna. De los 7 ECAs incluidos solo 3 presentaron resultados estadísticamente significativos, pero todos tuvieron fallas metodológicas impor tantes. La RS concluyó que no existe evidencia científica que avale el uso de los tratamientos. Los principales inconvenientes fueron bajo Nº muestral en todos los trabajos y realizar la comparación con otros tratamientos en vez de placebo. Conclusión: No se cuenta actualmente con adecuada evidencia para avalar o desaconsejar el tratamiento del MC en pediatría. La mejor opción es la conducta expectante acompañando a la familia y reforzando su carácter benigno y autolimitado. Opinion de experto Dr. Adrián Pierini: El mejor tratamiento costo-efectivo del MC es no realizar ningún tratamiento.


Introduction: Molluscum contagiosum (MC) is a commonskin disease in pediatrics. The lesions are pearly in appea-rance with a dimpled center, are independent, and mayappear anywhere on the body. Although the disease isbenign and self limited, it may esthetically and socially affect the child and his/her family. Objective: To conduct a systematic literature review to determine if there is scientific evidence on the safety and efficacy of different treatments for MC. Material and methods: A systematic literature search was conducted using the Medline, Lilacs, and Cochrane data bases, the grey literature, and Google Scholar, and collaboration of the Hospital Garrahan library. Search strategy the words “molluscum contagiosum” and “treatment” were used. RCTs, meta-analyses, and qualitative systematic reviews published from 1990 onward were selected.Studies in immunocompromised patients were excluded.The JAMA guides were used for the analysis. Results: 15 RCTs and one systematic review were found. Only eightstudies that met the criteria of internal validity were included. Of the seven RCTs included, only three presented statistically significant results and all had considerable methodological flaws. The systematic review concluded that noscientific evidence exists to support the use of treatment.The main weaknesses were small sample sizes in all stu-dies and the comparison with other treatments instead ofplacebo. Conclusion: Currently, no adequate evidence existsto support or advise against treatment of MC in the pedia-tric population. The best management is a “wait-and-see”approach accompanying the family and emphasizing thebenign and self-limiting character of the disease. Expertopinion of Dr. Adrián Pierini: The most cost-effective treat-ment of MC is no treatment at all.

ABSTRACT

Molluscum contagiosum [MC] is a common viral infection affecting children. A number of chemical and physical modalities are available for its treatment. To evaluate the efficacy and safety of cryotherapy versus 10% potassium hydroxide [KOH] solution in treating MC. 40 children with MC were divided into two groups. Cryotherapy [one freeze-thaw cycle] was done in group A [n=20] or 10% potassium hydroxide solution [KOH] was applied [group B, n=20] by the patient or a parent twice daily until 12 weeks. Patients were followed up at baseline, week 2, week 4, week 8, and week 12 for efficacy [defined as clearance of lesions] or side effects. By the end of study, 14 patients in group A [cryotherapy] and 17 patients in group B [KOH] were evaluable. All 14 [100%] patients in cryotherapy group and 16/17 [94.1%] in KOH group showed complete clearance of lesions. 100% patients in group A [cryotherapy] and 88.2% in group B [KOH] developed local side effects. However, these were mild and did not warrant discontinuation of treatment. 10% KOH solution is as effective as cryotherapy for the treatment of MC in children. However, KOH is relatively safe and more patient friendly therapy

ABSTRACT

El tratamiento de moluscos contagiosos gigantes y múltiples en pacientes HIV+ implica un gran desafío. La resolución espontánea se observa en pacientes inmunocompetentes, pero esto no ocurre habitualmente en individuos inmunocomprometidos. Se han empleado varias terapéuticas, sin embargo no se han reportado datos convincentes de tratamientos exitosos. Describimos dos pacientes HIV+ con moluscos contagiosos recalcitrantes, diseminados y gigantes, quienes respondieron favorablemente al tratamiento con láser de CO2. Durante el seguimiento de quince y dieciocho meses, no hemos observado recidivas en estos pacientes
