ABSTRACT
Se presenta un caso de dermatitis facial por Malassezia pachydermatis en un paciente de 34 años de edad, diagnosticado mediante clínica y estudio micológico. M. pachydermatis es una levadura que forma parte de la microbiota de mamíferos domésticos y animales salvajes, donde frecuentemente puede provocar dermatitis y otitis externa. En humanos, son escasas las infecciones por este agente, describiéndose desde infecciones superficiales hasta fungemias. En Chile se la ha encontrado como agente causal de pitiriasis versicolor y dermatitis seborreica principalmente en pacientes inmunocomprometidos.
We present a clinical case of facial dermatitis due to Malassezia pachydermatis in a patient of 34 years old, diagnosed by clinical and micology study. M. pachydermatis is a zoofilic yeast that is part of the microbiota of domestic mammals and wild animals, frequently causing dermatitis and external otitis. In humans, infections by this agent are very scarce, describing from superficial infections to fungemias. In Chile it has been found as causal agent of pitiriasis versicolor and seborrheic dermatitis mainly in inmunocompromised patients.

RESUMEN: Las infecciones en el territorio maxilofacial, son cuadros frecuentes, de origen polimicrobiano, con manifestaciones clínicas muy variables y que están asociadas a múltiples vías de ingreso de los microorganismos al territorio. Un gran porcentaje de estas infecciones se origina en la cavidad oral, principalmente en lesiones bacterianas que sufren los dientes. La compleja anatomía de la cabeza y el cuello, permiten que muchas de estas infecciones se diseminen por espacios profundos, llegando a comprometer órganos o regiones anatómicas adyacentes, que pueden llevar a cuadros clínicos de alto riesgo vital. Los casos clínicos presentados en este artículo corresponden a pacientes tratados en el hospital San Juan de Dios a causa de procesos infecciosos del territorio maxilofacial, por equipos multidisciplinarios.
ABSTRACT: Infections in the maxillofacial territory are frequent cases of polymicrobial origin, with very variable clinical manifestations and are associated with multiple entering pathways of microorganisms in the territory. A large percentage of these infections originate in the oral cavity, mainly in bacterial lesions that undergo experienced by the teeth. The complex anatomy of the head and neck allows many of these infections to spread through deep spaces, leading to compromising adjacent organs or anatomical regions, which can lead to high-risk clinical conditions. The clinical cases presented in this article correspond to patients treated at the San Juan de Dios hospital because of infectious processes of the maxillofacial territory, by multidisciplinary teams.

Infection with Clostridium difficile is a growing concern because of the increasing prevalence and spread of nosocomial infections. Emergence of the hypervirulent 027/NAP1/BI strain is also notable. Existing diagnostic methods have low sensitivity or are time-consuming. Therefore, establishing a rapid and accurate microbiological diagnostic assay is needed. We evaluated the Xpert C. difficile assay (Xpert CD assay; Cepheid, USA) to detect toxigenic C. difficile. This assay is a real-time multiplex PCR assay that can be used to detect toxigenic C. difficile strains and differentiate the C. difficile presumptive 027/NAP1/BI strain. A total of 253 loose stool specimens were collected and toxigenic cultures, VIDAS C. difficile A & B assays (VIDAS CDAB assay; bioMerieux, France), and the Xpert CD assay were performed. In comparison to toxigenic cultures, the sensitivity, specificity, and positive and negative predictive values were 100%, 94.6%, 83.1%, and 100%, respectively, for the Xpert CD assay and 40.8%, 98.0%, 100%, and 88.9%, respectively, for VIDAS CDAB assay. Because of the low prevalence of the PCR ribotype 027 in Korea, the evaluation of the usefulness of the Xpert CD assay for screening for the 027 strain was limited. The Xpert CD assay provides great sensitivity in diagnosing toxigenic C. difficile infection. In addition, this method has excellent usability because it is simple and fast.

Gemella morbillorum is a facultatively anaerobic Gram-positive coccus which forms part of the normal flora of the oro-pharynx, the upper respiratory and gastrointestinal tracts. It rarely causes human infection, more often in immunocompromised hosts. We report a case of periradicular abscess due to Gemella morbillorum occurring in a young immunocompetent adult and review previous reports of infections due to Gemella morbillorum in the literature

The clinical manifestations of secondary syphilis are variable and can mimic many skin diseases, mostly being generalized and symmetrical in distribution. Localized lesions of secondary syphilis are rarely seen in dermatology clinics. We report an unusual presentation wherein a patient had localized lesions over face and soles only. There is a need for increased awareness on the part of physicians to recognize new patterns of syphilitic infection, together with a willingness to consider the diagnosis of syphilis in patients with unusual clinical features

Gastroenteritis is one of the most important diseases in the world. This disease is more critical among children, people with immune deficiency and the sufferers from mal-nutrition. Shigella spp. as the most important cause of dysentery, causes much mortality around the world. Increasing antibiotic resistance is one of the major health problems. This research aimed to study the pattern of antibiotic resistance of Shigella spp. In Zanjan Shahid Beheshti Hospital. Shigella spp. was isolated from stool samples of diarrheic patients during 2003-2007 using common microbioloyic methods. They were examined for serotyping and antibiogram using disc diffusion method. Shigella spp were found in 134 out of 682 [19.6%] diarrheic stool samples. They comprised of 53% males and 47% females. The highest number of positive samples was found in August and the lowest number was seen in March. The shigella species isolated from 134 positive cultures, identified as sh.flexeneri [62.7%], sh.boydii [20.1%] and sh.dysenteriae [17.2%]. In the antibiogram, ciprofloxacin was the most sensitive antibiotic [88.8%] and Ampicillin showed the highest resistance [100%]. Due to irregular use of antibiotics and increasing antibiotic resistance to Shigella species it can be suggested that some of antibiotics can be omitted from the list of drug choice

Una de las complicaciones más serias de la celulitis facial bacterémica es la meningitis bacteriana aguda. En el presente estudio fueron revisadas retrospectivamente las fichas de 39 niños menores de 2 años ingresados con el diagnóstico de celulitis facial en la Unidad de Infecciosos del Hospital Roberto del Río entre agosto de 1992 y marzo de 1996. De los resultados destaca que de los 39 niños con celulitis facial estudiados 4 presentaron bacteremia a H. influenzae, 1 de éstos con meningitis asociada (2,5 por ciento de 39 casos). Los 4 casos tuvieron en común la ausencia de puerta de entrada. El análisis conjunto de este trabajo y otro anterior efectuado en la misma Unidad y publicado en 1993 permite concluir que la ausencia de puerta de entrada predice el riesgo de bacteremía y meningitis. Actualmente se siguen buscando criterios clínicos y de laboratorio en la celulitis facial que sugieran bacteremia y riesgo de compromiso meníngeo. Estos criterios orientarían a decidir en qué casos es necesario llevar a cabo un estudio acabado para descartar la meningitis bacteriana aguda como complicación

En un grupo de 38 lactantes de 1 a 21 meses de edad, hospitalizados por celulitis de mejilla entre 1986 y 1989, se compara el rendimiento de dos tipos de cultivo: el hemocultivo versus la punción aspirativa de la mejilla. El hemocultivo tuvo una positividad del 47,3%; la punción 31,5% y ambos métodos combinados 57,8%. La única especie recuperada fue H. influenzae tipo B. Ninguna complicación derivó de la punción, método que aparece exento de riesgos y complementa al hemocultivo como procedimiento diagnóstico
