Hepatitis E is an inflammatory liver disease caused by hepatitis E virus (HEV) infection, which is endemic in China, India, Nepal, and in several Asian and African countries, where the prevalence can be as high as 50%. In non-endemic countries, an increasing number of non-travel associated HEV has been reported in recent years, particularly in Europe. The authors describe the clinical case of a puerperal 24-year-old woman from Pakistan admitted to our Tertiary Care Medical Center with acute hepatic failure developed during the third trimester of her pregnancy. She was icteric with grade III encephalopathy and hypothermia. Laboratory values showed significant AST, ALT and LDH elevations of twelve times the upper normal limit, and total bilirubin was significantly elevated (41.20 mg/dL). Prothrombin time was prolonged (4 s) and factor V activity was diminished (15.1%). Extracorporeal albumin dialysis was initiated, but clinical deterioration occurred within 48 h, so she underwent OLT at day 4 post-admission. Severe forms of HEV are known to be more pronounced in pregnant women. Even though most of the described cases of acute hepatic failure associated to HEV during pregnancy had a favorable clinical course, some cases of fulminant liver failure and death are described. It is unknown whether liver transplant outcomes in this setting are different from other causes of acute liver failure. To our knowledge, this is the first case report in Portugal from a pregnant woman who developed hepatic failure due to fulminant hepatitis E that underwent successful liver transplantation.

Murine typhus or endemic typhus is a wide spread infectious disease, with a low prevalence in developed countries, but surely underdiagnosed. Its relative benignity, the similarity to other infectious diseases and the discretion of its epidemiologic chain, as well as the usual unexpectedness of its existence, makes its diagnosis more difficult. The clinical presentation and evolution of this case illustrate the necessity of being aware of this nosological entity.

Introduction: Rhinoscleroma is a rare, chronic, granulomatous disease that most frequently affects the upper respiratory tract, especially the nasal cavity and sometimes extends through the lower respiratory tract. Is associated with Klebsiella rhinoscleromatis, which is endemic in certain geographic regions namely Central America. The pathogenesis and risk factors remain unclear. Clinical case: We report a five years Old Portuguese boy, previously healthy, brought to the Emergency Department with epistaxis, without other accompanying signs or symptoms. The Otorhinolaryngologist (ORL) performed rhinoscopy and identified an intranasal bleeding mass. The MRI revealed an intranasal mass with extension to the ethmoid bone sinus, and performed biopsy. The histopathology was vital, making the diagnosis of Rhinoscleroma. The child had traveled abroad for the first time on vacations a year before to Dominican Republic. The bacteriologic exam identified a Klebsiella spp. sensible to the association of amoxicillin and clavulanic acid. Blood test performed excluded association of immunodeficiency. Since it’s a rare disease genetic study are under course. Monthly evaluation by ORL and pediatrician was performed which documented progressive reduction until total disappearing of the macro and microscopic lesion, and negative bacteriologic exam. Six months of antibiotic therapy were completed without any known secondary effects. The child remained asymptomatic up to the last visit, 3 months following treatment and has shown no evidence of recurrence. Conclusion: Globalization and free transit of people to areas far from origin countries here some rare diseases are endemic brings a new challenge to modern medicine. Sometimes vacations bring more than memories.

Dissemination of methicillin-resistant Staphylococcus aureus (MRSA) remains one of the most difficult challenges for prevention, control, and treatment of health care-associated infections. A survey and interviews were conducted on nurses from a hospital center. We found that most nurses' perceived risk of acquiring MRSA related to themselves (72%), other nurses (88.5%), and patients (97.8%). This perception influences attitudes, leading to compliance with the existing recommendations.

BACKGROUND: Geographical differences in asthma prevalence are currently accepted, but evidence is sparse due to the lack of multicentre studies using the same protocol. OBJECTIVES: To compare the prevalence of asthma and atopy among schoolchildren from Portuguese speaking countries (ISAAC and Portuguese Study) and evaluate some environmental variables, such as house dust mite exposure. MATERIAL AND METHODS: Significant random samples of schoolchildren studied with standard validated methods--questionnaires, skin prick tests, methacholine bronchial challenge tests; dust bed sampling for analysis of mite antigens. RESULTS: In the ISAAC study, in the 13-14 year-old age group, statistical significant differences were found, with higher wheezing prevalence in Brazil than in Portugal (two-fold). In the Portuguese Study, atopy prevalence ranged between 6.0 and 11.9% in Sal and S. Vicente (Cape Verde), up to 48.6 and 54.1% in Macau and Madeira. Active asthma had the higher values in Madeira (14.6%), and the lower in Macau (1.3%). Cape Verde had intermediate asthma prevalence (10.6 and 7.0%). The bronchial challenge test was positive in 25, 66 and 70% of asthmatic children from Sal, S. Vicente and Madeira respectively. Significant HDM antigen concentrations (Der p1) were found in Cape Verde and Madeira. CONCLUSIONS: There are significant variations in asthma and atopy prevalence between these pediatric populations. The reasons remain under discussion, but genetics linked to race, seem to play a central role, modulated by environmental and lifestyle variables.

We studied a group of 174 Portuguese children (aged 2 mo-16 y) who mostly traveled to tropical Portuguese-speaking countries and found an attack rate of 21.8% for travelers' diarrhea, much lower than previously described. We also showed that African rate analysis by region may hide significant differences between countries.
