Syndrome in question
Neurofibromatosis is extremely variable in its presentation. Segmental neurofibromatosis (SNF), which corresponds to NF-type 5 in the Riccardi classification, is a rare disorder. It may go unrecognized if few lesions are observed. We present a case of segmental neurofibromatosis in a 28 year-old patient who presented with multiple papules and nodules distributed in dermatomal fashion on the trunk. The histopathological examination of the lesions revealed a non-encapsulated, well-circumscribed spindle cell neoplasm, which was consistent with neurofibromas.info:eu-repo/semantics/publishedVersio
Doença de Crohn vulvoperineal responsiva ao metronidazole
Crohn's disease is a multisystem chronic granulomatous inflammatory disease that primarily affects the gastrointestinal tract. In the majority of the cases, the cutaneous manifestations follow the intestinal disease, but occasionally dermatological lesions are the inaugural event and may constitute the only sign of the disease. Vulvoperineal involvement is rare, may precede bowel symptoms by months to years and may go unrecognized. Due to the paucity of reports of Crohn's disease at this location and in the absence of randomized trials, there are no standard treatments for the cutaneous disease. We describe the case of a 47 year-old woman with vulvoperineal Crohn's disease without digestive involvement, that was successfully managed with metronidazole
Tunga Penetrans: Painful Lesions on the Feet—The First Imported Case from Guinea-Bissau
Tungiasis is an endemic disease in certain poor areas around the world. Imported infestations in travelers are becoming more frequent and can lead to considerable morbidity. We report a case of a 50 year-old-man who returned from a trip to Guinea-Bissau with an infection caused by Tunga penetrans

Exuberant cutaneous ulcers on the buttocks caused by multi-resistant
Cutaneous infection develops because of environmental and local factors, host immunity, and organism adherence and virulence. The authors report a case of exuberant cutaneous ulcers on the buttocks of a diabetic patient. Microbiologic examination allowed the identification of Klebsiella pneumoniae and complete resolution was achieved with the appropriate antibioti
Tumors of skin appendages – A 10-year review
Introdução: Os tumores dos anexos cutâneos representam um grupo heterogéneo de neoplasias benignas e malignas com diferentes diferenciações morfológicas.
Material e Métodos: Foi efectuado o estudo retrospectivo dos tumores dos anexos cutâneos diagnosticados na consulta externa do Serviço de Dermatologia do Centro Hospitalar do Porto, EPE-HSA entre 2000 a 2009.
Resultados: Foram diagnosticados 404 tumores dos anexos cutâneos. Apenas 3% dos tumores eram malignos. A maioria apresentou uma diferenciação (62,6 %) folicular.
Discussão: A revisão da literatura mostrou uma escassez de dados relativos a estudos retrospectivos dos tumores dos anexos cutâneos. Mais estudos são necessários para uma melhor caracterização epidemiológica destas entidades

Penile Kaposi sarcoma: A case of complete resolution with highly active antiretroviral therapy alone
Kaposi sarcoma remains an important cause of morbidity in HIV-infected patients. Regardless of the recent pharmacological progress, treatment of this malignancy is still disappointing. We report the case of a patient with Kaposi sarcoma in an unusual localization, the penis, which completely resolved with highly active antiretroviral therapy alon
Search for microorganisms in antiseptic, disinfectant and detergent dispensers of a local health care unit from Northeast Portugal
Introduction: Health care associated infections (HCAI) are among the main causes of
mortality worldwide, and of the increase of internment time and related costs. Many
HCAI acquired in hospitals result from improper disinfection practices of medical
devices and surfaces of the hospital environment, as also insufficient asepsis of health
professional’s skin [1,2].
Objectives: The main objectives of the present work were to verify the presence of
microorganisms in antiseptic, disinfectant and detergent dispensers from different
services of Bragança’s Local Health Care Unit, and to determine their resistance
profiles.
Materials and Methods: 151 Samples were collected from antiseptic (alcoholic
solution, povidone-iodine and chlorhexidine), disinfectant (70% alcohol) and detergent
(dermatological soap) dispensers, and futher plated in Columbia CNA + 5% sheep
blood and MacConkey agar. The identification and the bacterial antibiogram were
performed using Vitek 2.
Results and Discussion: Among the 151 samples plated, 25 exhibited
contamination, corresponding to a contamination percentage of 17%. The most
frequently identified and isolated microorganisms were Staphylococcus hominis, Sphingomonas paucimobilis and Staphylococcus epidermidis with a percentage of
20%, 20% and 16%, respectively. Micrococcus luteus/lylae, Rhizobium radiobacter,
Staphylococcus capitis, Pseudomonas luteola, Staphylococcus warneri,
Staphylococcus vitulinus, Kocuria kristinae and other gram-positive bacillus were
identified with less prevalence. The dermatological soap was the product with the
highest contamination percentage and it was in the Medicine services that more
contaminated products were found, while Surgery services showed the lowest
contamination. Some of the isolated bacteria showed important resistance profiles,
such as Staphylococcus hominis and Staphylococcus epidermidis, namely to betalactams
(oxacillin and amoxicillin/clavulanic acid) and quinolones (levofloxacin).
Conclusion: Although the main isolated microorganisms belong to a group of
commensal bacteria that do not cause problems to a person with a normal immunity
system, these are responsible for HCAI. Therefore, it is essential to develop protocols
for handling and packaging all the solutions in order to decrease the contamination
level and, consequently, the HCAI
