RESUMO
Introducción. La tuberculosis cutánea secundaria a la inyección con agujas es rara; se presenta en personal médico y de laboratorio, y en pacientes que reciben tratamientos percutáneos.Objetivo. Presentar seis pacientes con tuberculosis cutánea secundaria a tratamiento por mesoterapia.Materiales y métodos. Entre 1 y 4 meses después de la inyección en la piel glútea y abdominal de material no precisado, como tratamiento para la obesidad y la celulitis, cinco mujeres y un hombre desarrollaron pápulas, nódulos y senos de drenaje de material seroso en los sitios de inoculación, interpretados clínicamente como infección por micobacterias no tuberculosas. Se practicaron cultivos de las secreciones y de las biopsias de piel para la identificación fenotípica y estudio de histopatología. Con los resultados iniciales se realizaron pruebas moleculares de PRA (PCR-restriction pattern analysis) en las biopsias de piel y estudio ampliado de los pacientes.Resultados. Se demostró Mycobacterium tuberculosis en los cultivos, hallazgo confirmado por la técnica de PRA en las biopsias incluidas en parafina. Los pacientes no habían padecido tuberculosis. Las placas de tórax fueron normales y la tuberculina midió entre 17 y 20 mm. Cinco curaron con terapia antituberculosa y otro curó espontáneamente luego de la resección-biopsia de la lesión más grande. No se encontraron adenopatías satélites ni recurrencias. Conclusiones. Se demostró una nueva forma de adquirir la tuberculosis cutánea. Esta es la segunda demostración de tuberculosis cutánea por mesoterapia en Colombia. El estudio de las lesiones de la piel en el sitio de la inyección cutánea debe incluir pruebas para detectar micobacterias, entre ellas M. tuberculosis. Las autoridades sanitarias deben prestar atención y prevenir esta modalidad de adquirir la tuberculosis.
Introduction. Cutaneous tuberculosis as a result of a needle injection is a rare event; it generally occurs among medical and laboratory personnel and among patients receiving percutaneous treatment. Objective. Six patients are presented who developed cutaneous tuberculosis after mesotherapy cosmetic treatment. Material and methods. One to four months after injection of an unknown product as treatment for obesity and cellulites, five women and a man developed papules, nodules and drainage of wax like material at the inoculated sites; this was interpreted clinically as a non tuberculous mycobacterium infection. Skin biopsies were taken for a histopathologic study; the biopsy and exudates were cultured to make a phenotypic identification. Polymerase chain reaction and restriction enzyme pattern analyses (PCR-restriction pattern analysis)) procedures were applied to the skin biopsies. Results. Mycobacterium tuberculosis was confirmed in the culture and by PRA analysis in the paraffin-embedded biopsies. The patients had never had tuberculosis. Their thoracic X rays were normal and the size of the tuberculin reaction was 17 to 20 mm. Five patients recovered with antituberculosis treatment and the sixth spontaneously healed after the removal of the largest cutaneous module. No satellite adenopathy or recurrences were observed. Conclusions. A previously undescribed mode of acquisition cutaneous tuberculosis was described. This was the second incident of a demonstrated cutaneous tuberculosis following mesotherapy in Colombia. Skin lesions induced by injections must be tested to detect mycobacterias to include M. tuberculosis.

INTRODUCTION: Cutaneous tuberculosis as a result of a needle injection is a rare event; it generally occurs among medical and laboratory personnel and among patients receiving percutaneous treatment. OBJECTIVE: Six patients are presented who developed cutaneous tuberculosis after mesotherapy cosmetic treatment.

OBJECTIVE: To detect the presence of rifampin- and dapsone-resistant strains of Mycobacterium leprae in three patients with recurring leprosy and clinically-suspected antimicrobial resistance through molecular techniques. METHODS: A retrospective, descriptive study was conducted of three multibacillary patients at the "Agua de Dios" Sanitarium in Cundinamarca, Colombia, that presented leprosy relapses that were documented by medical history, bacilloscopy, and biopsy. Biopsies were taken of the skin lesions and the bacteria were subject to DNA extraction and purification. Regions of the rpoB and folP1 genes associated with antimicrobial resistance were amplified and subjected to touch-down polymerase chain reaction and the amplified products were sequenced using the Sanger method. RESULTS: A punctual mutation was identified in nucleotide 1367 of the rpoB gene in two of the samples studied. This mutation was not found in the folP1 gene of any of the three patients. CONCLUSIONS: The mutation identified showed strains of rifampin-resistant M. leprae in two of the three patients with recurring leprosy. Mutations that indicate dapsone-resistance were not detected in any of the three patients.

OBJETIVO: Detectar la presencia de cepas de Mycobacterium leprae resistentes a la rifampicina y la dapsona en tres pacientes con recurrencia de lepra y sospecha clínica de resistencia antimicrobiana, mediante la aplicación de técnicas moleculares. MÉTODOS: Se realizó un estudio descriptivo retrospectivo en tres pacientes multibacilares del Sanatorio de Agua de Dios, Cundinamarca, Colombia, que habían presentado recidivas de lepra documentadas por su historia clínica, baciloscopia y biopsia. Se obtuvieron biopsias de lesiones cutáneas que se procesaron para la extracción y purificación del ADN bacilar. Se amplificaron regiones de los genes rpoB y folP1 asociadas con la resistencia antimicrobiana, mediante la reacción en cadena de la polimerasa "touch-down" y se secuenciaron los productos amplificados mediante el método de Sanger. RESULTADOS: Se detectó una mutación puntual en el nucleótido 1367 del gen rpoB en dos de las muestras estudiadas. No se encontró la mutación estudiada en el gen folP1 en ninguno de los tres pacientes. CONCLUSIONES: La mutación identificada demostró la presencia de bacilos de M. leprae resistentes a la rifampicina en dos de los tres pacientes estudiados con recurrencia de la enfermedad. No se detectó la mutación indicadora de resistencia a la dapsona en ninguno de los tres pacientes.

OBJECTIVE: Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. METHODS: A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin biopsies were performed when the clinical findings suggested leprosy. Anti-phenolic glycolipid antibodies in blood were determined in special cases. RESULTS: 86 % of the 2 844 school children were examined; 833 had skin diseases and 16 % of these required evaluation by specialists. Four new cases of paucibacillary leprosy, two indeterminate and two primary polyneuritic cases were found. Pediculosis capitis, pityriasis alba, tinea versicolor, hypopigmented nevus, insect bites and miliaria were frequently detected. BCG vaccination scars were absent in 387 children; following several logistical problems, they were vaccinated. Four children had signs of childhood abuse. An 11-year-old girl presented hypopigmented mycosis fungoides. All diseases and conditions found were treated. The community received information regarding the results, emphasising the importance of an early diagnosis of leprosy. CONCLUSIONS: The incidence of leprosy found (16/10,000) was 123 times higher than the rest of the country's incidence. It is advisable to continue clinical examinations in Agua de Dios and research into risk factors for acquiring leprosy.

Objetivo: Buscar lepra, otras enfermedades de la piel y la cicatriz BCG, en escolares de Agua de Dios, municipio con la más alta prevalencia de lepra en Colombia: 23-39/10 000; educar y difundir los resultados en la comunidad. Métodos: Se hizo examen clínico de los niños por enfermeras, médicos internos y generales y por expertos en lepra. Cuando la clínica lo indicaba, se practicaron baciloscopias y biopsias de piel. En pocos casos se buscaron anticuerpos en sangre contra el glicolípido fenólico 1, del bacilo de Hansen. Resultados: Se examinaron 86 por ciento de los 2 844 escolares de las 17 instituciones del municipio; 833 tuvieron patologías cutáneas, de los cuales 16 por ciento requirieron el examen por expertos. Se demostraron cuatro casos nuevos de lepra paucibacilar, dos indeterminados y dos polineuríticos primarios. Las entidades más frecuentes fueron: pediculosis, pitiriasis alba, pitiriasis versicolor, nevus hipocrómicos, picaduras de insectos y miliaria. Cuatro niños tuvieron maltrato infantil y una niña de 11 años, micosis fungoides hipocromiante. La vacunación BCG se aplicó en 387 niños que no la habían recibido. Se trataron las condiciones encontradas. Se informó a la comunidad sobre las enfermedades detectadas, las funciones de la piel y sus cuidados generales, enfatizando la importancia del diagnóstico temprano de la lepra. Conclusiones: La incidencia de lepra encontrada (16/10 000), es la más alta en Colombia, 123 veces mayor que la global del país. Su búsqueda activa demostró enfermedad paucibacilar, sin discapacidades y otras enfermedades cutáneas importantes. Es recomendable persistir con este examen clínico y con la investigación de los factores predisponentes para adquirir la enfermedad.

We developed a multiplex PCR-based methodology for nasopharyngeal samples maintained in egg thioglycolate antibiotic and skim milk-tryptone-glucose-glycerol media to identify and serotype the most important serotypes of Streptococcus pneumoniae that cause invasive disease in children. This technique can be used to study the epidemiology of pneumococcal colonization and the effect of conjugate vaccines.
