ABSTRACT

Trichodysplasia spinulosa is a rare disease that occurs in the setting of immunosuppression, associated with tolerogenic therapy used in allograft recipients or patients with hematologic malignancies. Clinically, it is characterized by a centrofacial cutaneous eruption of erythematous papules with a central keratinous spicule, often associated with variable degrees of alopecia. Histologic findings are characteristic, and electron microscopy reveals the presence of trichodysplasia spinulosa associated polyomavirus. We report a 47-year-old woman with idiopathic autoimmune pancytopenia refractory to diverse immunosuppressant regimens, with clinical and pathologic findings compatible with the disease, in whom complementary studies were required to exclude other differential diagnoses.

ABSTRACT

Abstract: A 54 year-old woman with a 3-year history of rheumatoid arthritis (RA) consulted us because of weight loss, fever and skin eruption. On physical examination, erythematous plaques with a pseudo-vesicular appearance were seen on the back of both shoulders. Histological examination was consistent with rheumatoid neutrophilic dermatosis (RND). After 3 days of prednisone treatment, the skin eruption resolved. RND is a rare cutaneous manifestation of seropositive RA, characterized by asymptomatic, symmetrical erythematous plaques with a pseudo-vesicular appearance. Histology characteristically reveals a dense, neutrophilic infiltrate with leucocitoclasis but without other signs of vasculitis. Lesions may resolve spontaneously or with RA treatment. This case illustrates an uncommon skin manifestation of active rheumatoid arthritis.

ABSTRACT

Abstract The epithelial ovarian cancer (EOC) has been underdiagnosed because it does not have a specific clinical presentation, and the signs and symptoms are similar to the irritable bowel syndrome and pelvic inflammatory disease. EOC is less common than breast and cervical cancer, but it is more lethal. On the whole, EOC has an early dissemination to peritoneal cavity, which delays a timely diagnosis and increases the rate of advanced diagnosed disease. The diagnosis usually surprises the women and the primary care physician. Therefore, it is necessary to count on prevention and early diagnosis programs. EOC has 80% response to surgical treatment, but nearly 70% of the patients may relapse in five years. The objectives of this document are presenting a summary of the EOC epidemiology and comment about advancements in prevention, diagnosis, and treatment of this cancer. That will raise awareness about the importance of this disease.


Resumen El cáncer ovárico epitelial (COE) ha sido subdiagnosticado debido a que no tiene presentación clínica específica y a que los signos y síntomas son similares al síndrome de colon irritable y a la enfermedad inflamatoria pélvica. Es menos común que el cáncer de mama o el cervicouterino, pero es más letal. En general, tiene diseminación temprana a cavidad peritoneal, lo cual retrasa un pronóstico oportuno e incrementa la tasa de diagnóstico de enfermedad avanzada. Usualmente, el diagnóstico sorprende a la mujer y al médico de primer contacto. Entonces, es necesario contar con programas de prevención y diagnóstico temprano. El COE tiene 80% de respuesta quirúrgica, pero cerca de 70% de las pacientes puede recaer en cinco años. Los objetivos de este documento son presentar un resumen de la epidemiología del COE y comentar los avances en prevención, diagnóstico y tratamiento de este cáncer. Esto despertará la conciencia acerca de la importancia de esta enfermedad.

ABSTRACT

Acute generalized exanthematous pustulosis is an uncommon skin eruption, characterized by fever and the rapid onset of disseminated, non-follicular, sterile pustules, over an erythematous skin background. It is usually classified as a severe cutaneous adverse drug reaction, whose most relevant triggers are antibiotics and anticonvulsants. However, viral and bacterial infections have also rarely been associated with this dermatosis. We report the case of a patient, who developed lesions of acute generalized exanthematous pustulosis as an extrapulmonary manifestation of Mycoplasma pneumoniae infection.

ABSTRACT

AbstractBACKGROUND:Disseminating information derived from systematic reviews is a fundamental step for translating evidence into practice.OBJECTIVE:To determine which features of dermatological SR are associated with systematic review dissemination, using citation rates as an indicator.METHODS:Dermatological systematic reviews published between 2008 and 2012 were obtained from Scopus, the ISI Web of Sciences and the Cochrane Skin Group. Bibliometric data of every systematic review were collected and analyzed.RESULTS:A total of 320 systematic reviews were analyzed. Univariable analysis showed that the journal impact factor, number of authors, and total references cited were positively associated with the number of citations. There was a significant difference in the median number of citations with regard to the corresponding author's country, type of skin disease, type of funding, and presence of international collaboration. Cochrane reviews were significantly associated with a lower number of citations. Multivariable analysis found that the number of authors, number of references cited and the corresponding author from United Kingdom were independently correlated with many citations. Cochrane systematic reviews tended to be independently associated with a lower number of citations.CONCLUSIONS:Citation number to systematic reviews may be improving by increasing the number of authors, especially collaborative authors, and the number of cited references. The reasons for the association of Cochrane SRs with fewer citations should be addressed in future studies.

ABSTRACT

Abstract

We report the case of a 42-year-old female with a 5-year history of rheumatoid arthritis treated with Rituximab and Azathioprine. Three months after the initiation of Azathioprine, the patient started with dry cough and noted the rapid development of multiple subcutaneous nodules on her right leg. CT scan of the chest demonstrates pulmonary nodulosis. Skin biopsy was compatible with rheumatoid nodule. A diagnosis of "accelerated cutaneous and pulmonary nodulosis" was considered. Azathioprine was discontinued and Rituximab was restarted. Two months later, most of the subcutaneous nodules had disappeared. This is the second case report of accelerated rheumatoid nodulosis in association with Azathioprine treatment.

ABSTRACT

Tuberculosis remains a major global health problem. Cutaneous involvement is a rare manifestation of tuberculosis infection. Sporotrichoid clinical pattern consists of a linear arrangement of nodules along the lymphatic vessels. It is often seen in sporotrichosis. Few cases have been reported of cutaneous tuberculosis presenting as a sporotrichoid clinical pattern. We describe a 84-year-old female with ulcerative nodules on upper extremity caused by Mycobacterium tuberculosis, emphasizing the importance of considering cutaneous tuberculosis in the differential diagnosis of sporotrichoid lesions.


En la actualidad, la tuberculosis sigue siendo un problema de salud pública en el mundo. El compromiso cutáneo es una manifestación poco frecuente de la infección por Mycobacterium tuberculosis. El patrón esporotricoide se refiere a la disposición lineal de los nódulos cutáneos siguiendo el trayecto de los vasos linfáticos, forma de presentación característica de la esporotricosis, de ahí su nombre. Muy pocos casos han sido reportados sobre tuberculosis cutánea con patrón esporotricoide. Se presenta el caso clínico de una mujer de 84 años con nódulos ulcerativos de disposición lineal en miembro superior causados por Mycobacterium tuberculosis, destacando la importancia de incluir a la tuberculosis cutánea en el diagnóstico diferencial de lesiones con patrón esporotricoide.

ABSTRACT

Introduction: The reported literature about the types of cutaneous adverse antibiotic reactions (ATB-CAR) and the responsible antimicrobial class is scarce. Aim: to describe the clinical and histopathological profile of these reactions, and potential associations between different types of ATB-CAR and causal antibiotic class in a tertiary hospital in Chile. Material and Methods: Cross-sectional retrospective study performed at the Hospital of the Pontificia Universidad Católica de Chile. Results: A total of 58 patients were included. The most common type of ATB-CAR was morbilliform (n: 37, 63.8%). The antibiotics most frequently involved were the penicillins and cephalosporins (n: 34, 69.3%). The most common histological pattern in all types of ATB-CAR was superficial perivascular dermatitis with or without spongiosis. There was significant association between urticarial, morbilliform, DRESS and PEGA types, with the use of penicillins, cephalosporins, cotrimoxazole, and lincomycin, respectively (n: 4,100%, n: 15, 40.5%, n: 2; 50%, n: 1, 50%, p < 0.05, respectively). Discussion: This is the first description of the ATB-CAR patterns in South American hospitalized patients. Both clinical and histopathological patterns of ATB-CAR are similar to other published series, however the types of causal antibiotics are different.


Introducción: La literatura médica reportada acerca de los tipos de reacciones cutáneas adversas a antimicrobianos (ATM-cRAM) y la clase de antimicrobiano responsable es escasa. Objetivo: Describir el perfil clínico e histopatológico de estas reacciones, y establecer posibles asociaciones entre los distintos tipos de ATM-cRAM y la clase de antimicrobiano causal, en un hospital terciario en Chile. Material y Método: Estudio transversal analítico retrospectivo realizado en el Hospital de la Pontificia Universidad Católica de Chile. Resultados: Fue incluido un total de 58 pacientes. El tipo más frecuente de ATM-cRAM fue el morbiliforme (n: 37; 63,8%). Los antimicrobianos más frecuentemente implicados fueron penicilinas y cefalosporinas (n: 34; 69,3%). El patrón histopatológico más frecuente en todos los tipos de ATM-cRAM fue el de dermatitis perivascular superficial, con o sin espongiosis. Hubo asociación significativa entre las ATM-cRAM tipo urticaria, morbiliforme, DRESS y PEGA, con el uso de penicilinas, cefalosporinas, cotrimoxazol y lincomicina, respectivamente (n: 4,100%; n: 15, 40,5%; n: 2; 50%; n: 1; 50%, p < 0,05, respectivamente). Discusión: Este estudio corresponde a la primera descripción de los patrones de ATM-cRAM en pacientes hospitalizados sudamericanos. Tanto los patrones clínicos como histopatológicos de ATM-cRAM son similares a otras series publicadas; sin embargo, los tipos de antimicrobianos causales no coinciden con lo previamente descrito.

ABSTRACT

Existen diversas formas de presentar los resultados de un ensayo clínico controlado (ECC) o metaanálisis (MA). En este apartado analizaremos punto por punto el significado y forma de calcular las distintas medidas de efecto tanto en ECC como MA, ya que en ambos tipos de trabajos, los resultados se presentan en forma similar. Es importante considerar que el lector de un ECC o MA debe comprender cuál es el valor que tienen estos resultados, en cuanto a la magnitud de beneficio o daño para un paciente en particular, más allá de saber si tienen o no tienen significación estadísticas. Por otro lado, aparte de la magnitud del efecto de determinada intervención, es necesario considerar la exactitud de esta estimación, lo que se logra con el uso de los intervalos de confianza.

ABSTRACT

Se realizó este estudio para determinar la frecuencia de desnutrición en el hospital, relacionarla con las variables demográficas, la enfermedad de base, la presencia de neoplasias, y con los servicios de la institución. Se estudiaron 242 pacientes, ingresados, a los cuales se les realizó una encuesta global subjetiva sobre el estado nutricional y otra donde se tomaron datos de la historia clínica (diagnóstico y presencia de cáncer, entre otras). En el análisis estadístico se valoró la asociación entre el estado nutricional y algunas variables, utilizándose en todas las pruebas el nivel de significación de 0,05. Se encontró 39,3 por ciento de desnutrición en el hospital, predominando el servicio de quemados, la unidad de cuidados intermedios quirúrgicos, geriatría y medicina. La mayor frecuencia de desnutridos resultó con las enfermedades digestivas y respiratorias. Los pacientes con neoplasias presentaron mayor desnutrición. La desnutrición hospitalaria se encontraba elevada, por lo que se debe realizar un programa de intervención alimentario nutricional efectivo para minimizarla
