Seroprevalence of Protective Antibodies Against Influenza and the Reduction of ...

Background: Seroepidemiological studies provide estimates of population-level immunity, prevalence/incidence of infections, and evaluation of vaccination programs. We assessed the seroprevalence of protective antibodies against influenza and evaluated the correlation of seroprevalence with the cumulative annual influenza incidence rate. Methods: We conducted an annual repeated cross-sectional seroepidemiologica...

Cross-Protection to New Drifted Influenza A(H3) Viruses and Prevalence of Prote...

INTRODUCTION: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portugu...

Bottlenose dolphin Tursiops truncatus group dynamics, site fidelity, residency ...

The bottlenose dolphin Tursiops truncatus is one of the most frequently sighted cetacean species in the Madeira Archipelago (North-East Atlantic); however, little is known about its population ecology in these waters. Photo-identification undertaken during systematic, non-systematic and opportunistic surveys conducted between 2001 and 2012 was used to assess group dynamics, site fidelity, residency and movement...

Collagen Type IV-Related Nephropathies in Portugal: Pathogenic COL4A5 Mutations...

Alport syndrome (AS) is caused by pathogenic mutations in the genes encoding α3, α4 or α5 chains of collagen IV (COL4A3/COL4A4/COL4A5), resulting in hematuria, chronic renal failure (CRF), sensorineural hearing loss (SNHL) and ocular abnormalities. Mutations in the X-linked COL4A5 gene have been identified in 85% of the families (XLAS). In this study, 22 of 60 probands (37%) of unrelated Portuguese families, wi...

Acute kidney injury in pregnancy: a clinical challenge

The incidence of acute kidney injury in pregnancy declined significantly over the second half of the 20th century; however, it is still associated with major maternal and perinatal morbidity and mortality. A set of systemic and renal physiological adaptive mechanisms occur during a normal gestation that will constrain several changes in laboratory parameters of renal function, electrolytes, fluid and acid-base ...

Kidney transplantation and diabetes: posttransplantation malignancy

Risk factors for chronic graft dysfunction in 918 renal transplants.

Febrile coma and disseminated intravascular coagulation following heat stroke.

A clinical case that occurred in a 42 years old female and which fulfils the diagnostic criteria for the entity described as Heat Stroke is presented. In this case, besides the usual manifestations of hyperpyrexia without sweating along with consciousness disorders, features of consumptive coagulopathy, rhabdomyolysis and well marked laboratory liver dysfunction have also been found. The severity of this situat...

Sarcoidosis as a cause of febrile++ syndrome of unknown origin. Retrospective s...

The authors report the results of a retrospective study of patients admitted to the Department of Infectious Diseases of Santa Maria Hospital with the diagnosis of sarcoidosis, from June 1982 to August 1991. Seven out of eight patients, were admitted due to fever of unknown origin. The results are discussed and the literature on sarcoidosis is also reviewed.; The authors report the results of a retrospective st...

The authors report a case of a 70-year-old-woman, admitted to the Intensive Care Unit for Infectious Diseases of the Santa Maria Hospital, with the diagnosis of EC. The literature on EC is also reviewed.; Emphysematous cholecystitis (EC) is a rare and dramatic disease that requires prompt therapeutic pro...
