ABSTRACT

Abstract In addition to the infestations and bacterial infections reported in part I, the study of entomodermoscopy also involves descriptions of dermoscopic findings of a growing number of viral and fungal infections, among others. In this article, the main clinical situations in viral infections where dermoscopy can be useful will be described, that is in the evaluation of viral warts, molluscum contagiosum, and even in recent scenarios such as the COVID-19 pandemic. As for fungal infections, dermoscopy is particularly important, not only in the evaluation of the skin surface, but also of skin annexes, such as hairs and nails. The differential diagnosis with skin tumors, especially melanomas, can be facilitated by dermoscopy, especially in the evaluation of cases of verruca plantaris, onychomycosis and tinea nigra.

ABSTRACT

La infección por Nocardia spp. no es común en pacientes inmunocompetentes. El tratamiento antimicrobiano empírico dirigido según las regiones anatómicas, no contempla las particularidades del germen y el análisis microbiológico se hace necesario para el tratamiento específico. A continuación, se presenta el caso de una paciente previamente sana, inmunocompetente y sin factores de riesgo conocidos para la infección por Nocardia spp., con evidencia de compromiso en el parénquima pulmonar y la piel, que posteriormente desarrolló varios abscesos cerebrales.


The infection by Nocardia spp is not common in immunocompetent patients. The empirical antimicrobial treatment directed by anatomical regions does not contemplate the particularities of the germ and the microbiological analysis is necessary for the specific treatment. We present the case of a previously healthy and immunocompetent patient, without known risk factors for Nocardia spp. infection, with evidence of involvement of the pulmonary parenchyma and the skin and subsequent development of multiple brain abscesses.

ABSTRACT

Abstract Protothecosis is a rare condition caused by the aclorophylated algae of the genus Prototheca. In humans, protothecosis, caused mainly by P. wickerhamii, manifests itself in three forms: cutaneous, articular and systemic. It can occur in both immunocompetent and immunosuppressed individuals, being much more common in the latter. We present a new case of protothecosis in Brazil in a kidney transplant recipient.

ABSTRACT

Resumen Las infecciones de piel y tejidos blandos (IPTB) representan la tercera causa de consulta por enfermedad infecciosas a los servicios médicos, después de las infecciones respiratorias y urinarias. Se presenta una guía de práctica clínica (GPC) con 38 recomendaciones basadas en la evidencia, graduadas bajo el sistema SIGN, para el diagnóstico y tratamiento de pacientes adultos con IPTB en el contexto colombiano, posterior a un proceso de adaptación de GPC publicadas y la búsqueda sistemática y síntesis de literatura para la actualización de la evidencia científica. Además, se realizó un consenso de expertos para la evaluación de las potenciales barreras para la implementación de las recomendaciones y la evaluación del grado de recomendación en el contexto local.


Abstract Skin and soft tissue infections (SSTI) represent the third leading cause of infectious disease consultation for medical services after respiratory and urinary tract infections. This document generates a clinical practice guideline with 38 recommendations based on evidence, graduated under the SIGN system for the diagnosis and treatment for SSTI infections in adult patients in Colombia, following a process of adaptation of guidelines published, and the systematic search and synthesis of literature for the updating of scientific evidence. In addition, a consensus of experts was made for the evaluation of the potential barriers for the implementation of the recommendations and the evaluation of the degree of recommendation in the local context.

ABSTRACT

La infección por VIH confiere al portador la susceptibilidad para desarrollar un conjunto de infecciones que normalmente no serían encontradas en un paciente inmunocompetente. En Colombia, en el año 2015, se reportaron 11.606 casos de infección por VIH. En este escrito documentamos el caso de un paciente con diagnóstico de infección por VIH, el cual desarrolló lesiones típicas de infección por el virus Varicela Zoster, y se documentó la evolución de las lesiones vesiculares hacia flictenas con necrosis local. Dada la presentación del caso, el diagnóstico de lesiones en piel en pacientes inmunocomprometidos o con infección por VIH se convierte en un reto para el profesional de la salud a la hora de establecer un diagnóstico etiológico, a fin de establecer un adecuado tratamiento de acuerdo a este.


HIV infection makes HIV carriers susceptible to develop a group of infections that would not normally be found in an immunocompetent patient. In Colombia, a total of 11,606 cases of HIV infection were reported in 2015. This paper documents the case of a patient diagnosed with HIV infection, who developed lesions typically caused by the varicellazoster virus. These vesicular lesions evolved into phlyctenas with local necrosis. Given the case presentation, the diagnosis of skin lesions in immunocompromised or HIV-infected patients becomes a challenge for health professionals when determining an etiological diagnosis, in order to establish an appropriate treatment.

ABSTRACT

Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever in a 19-year-old patient who presented maculopapular exanthema in the palmar region and upper limbs, lymphadenopathy, fever, chills, headache, conjunctival hyperemia, nausea, vomiting, dyspnea, myalgia, developing neurological signs and abdominal pain. He was treated with doxycycline with clinical improvement. We emphasize the importance of the recognition of this disease by dermatologists as cutaneous manifestations are the key findings to establish early diagnosis and prevent complications.

ABSTRACT

Las infecciones de piel y partes blandas son una causa frecuente de consulta en los centros de atención primaria de la salud. Los datos de la epidemiología local de estas infecciones son escasos; el Staphylococcus aureus y el Streptococcus pyogenes son los principales agentes etiológicos. La emergencia, en los últimos años, de cepas de S. aureus meticilino resistentes provenientes de la comunidad y S. pyogenes resistentes a eritromicina plantea controversia en la elección del tratamiento empírico inicial. Este consenso nacional está dirigido a médicos pediatras, de familia, dermatólogos, infectólogos y otros profesionales de la salud. Trata el manejo clínico, especialmente el diagnóstico y tratamiento, de las infecciones de piel y partes blandas de origen bacteriano provenientes de la comunidad en pacientes inmunocompetentes menores de 19 años de edad.


Skin and soft tissue infections are a common reason for consultation in primary health care centers. Data from the local epidemiology of these infections are rare, but Staphylococcus aureus and Streptococcus pyogenes are known to be the major etiologic agents. The appearance in recent years of community-originated strains of methicillin-resistant S. aureus and erythromycin-resistant pyogenes raises controversy in the choice of initial empirical treatment. This national consensus is for pediatricians, dermatologists, infectologists and other health professionals. It is about clinical management, especially the diagnosis and treatment of community-originated skin and soft tissue infections in immunocompetent patients under the age of 19.

ABSTRACT

Objective To investigate the pathogens and their drug resistance of neonatal skin infection in Maternal-Neonatal Unit to provide evidence for rational selection of antibiotics.Methods Secretions of skin lesions from newborns with skin infections delivered in Maternal-Neonatal Unit,Department of Obstetrics of Beijing Daxing People's Hospital from Jan.2009 to Dec.2010 were collected,cultured and identified for bacterial serotype.Antibiotic resistances of pathogens were determined.Enumeration data was presented by frequency and rate.The difference between groups was compared with Chi-square test.Results Two hundred and six newborn skin infection cases were diagnosed,which accounted for 2.3% of all newborns (n=9131) delivered in the hospital during the study period.Two types of skin infection were identified,impetigo (n=192,93.2%) and omphalitis (n=14,6.8%).Totally 154 pathogens were found,including 95 (61.7%) Gram-positive cocci and 59 (38.3 %) Gram-negative bacilli.The major pathogens among Gram-positive cocci were Staphylococcus aureus (45/154, 29.2%), followed by Staphylococcus epidermidis and Staphylococcus haemolyticus.Staphylococcus was sensitive to Cefazolin,Amoxicillin/clavulanic acid and Piperacillin/tazobactam,while resistant to Penicillin,Ampicillin and Erythromycin.The major pathogens among Gram-negative bacilli were Enterobacter cloacae (19/154,12.3%),followed by Escherichia coli and Klebsiella pneumoniae.Drug resistance rate of Gram-negative bacilli was high in penicillin,aminoglycosides and cephalosporins,while they were sensitive to piperacillin/tazobactam,Ampicillin/sulbactam,carbapenems and Quinolones.Conclusions Gram-positive cocci are the main pathogens of neonatal skin infection in the Maternal-Neonatal Unit,and among which Staphylococcus aureus is the major pathogen.Multi-drug resistance is common in the identified pathogens.Attentions should be paid to use antibiotics reasonably according to drug sensitivity test.

ABSTRACT

Paciente de 30 anos, do sexo masculino, apresentou, após vacinação contra influenza comum, dor intensa, edema e eritema em membro superior esquerdo no local da aplicação e febre contínua não aferida. Foi hospitalizado, porém houve agravamento progressivo do quadro e resistência ao tratamento com anti-inflamatórios e antibióticos, culminando em queda do estado geral, formação de coleção no local e convulsão febril. Optou-se por tratamento cirúrgico, submetendo-se o paciente a procedimentos para fasciotomia, desbridamento, drenagem de coleção e sutura de extenso ferimento em membro superior esquerdo.


A 30-year-old male patient, after being vaccinated against the common influenza, presented severe pain, swelling and erythema at the site of injection on the left upper limb and had continuous fever that was not checked. He was admitted to the hospital,, but his clinical condition got worse, with no response to treatment with anti-inflammatory drugs and antibiotics. He developed an abscess at the site of vaccine injection, and high fever with febrile seizures. Surgical treatment was chosen, and the patient underwent debridement and drainage of the abscess, upper arm fasciotomy and repair of the extensive surgical wounds of the left arm.

ABSTRACT

Lacaziose é infecção crônica causada pelo fungo Lacazia loboi, originalmente descrita por Jorge Lobo (1931) em paciente oriundo da Amazônia brasileira. Manifesta-se, sobretudo, por lesões cutâneas queloidiformes. Relata-se o caso de paciente com placa eritêmato-violácea, cuja hipótese diagnóstica inicial foi de hanseníase dimorfa tuberculóide, doença também endêmica na região amazônica. Ressalta-se a importância da inclusão de formas paucibacilares de hanseníase no diagnóstico diferencial da lacaziose.


Lacaziosis is a chronic skin infectious disease caused by the fungus Lacazia loboi, which usually results in indolent cutaneous keloid-like lesions. It was first described by Jorge Lobo, in 1931, in a patient from the Amazon region. We report a case of lacaziosis, manifested by an erythematous infiltrated plaque, causing misdiagnosis with paucibacillary leprosy, since both diseases are endemic in Amazon basin.
