The girl from the Church of the Sacrament: a case of congenital syphilis in XVIII century Lisbon

Syphilis is a sexually or congenitally transmitted infectious disease with an impact on the health of human populations that has undergone important cycles in different countries and periods of history. Its presence was first diagnosed in Europe in the late XIV century. In Portugal, although there are various written records of the infection in the last centuries, there are rare references to it in archeological findings (mummified bodies are also rare in Portugal). The current study describes a probable case of congenital syphilis in an 18-month-old girl buried in the Church of the Sacrament in Lisbon. Her body, dating to the XVIII century, was found mummified together with dozens of others, still not studied. Symmetrical periostitis of the long bones, osteitis, metaphyseal lesions, left knee articular, and epiphyseal destruction, and a rarefied lesion with a radiological appearance compatible with Wimberger's sign all point to a diagnosis of congenital syphilis. The diagnosis of this severe form of the infection, possibly related to the cause of death in this upper-class girl, calls attention to the disease's presence in XVIII century Lisbon and is consistent with the intense mobilization at the time in relation to the risks posed by so-called heredosyphilis. It is the first case of congenital syphilis in a child reported in archeological findings in Portugal, and can be correlated with other cases in skeletons of adults buried in cemeteries in Lisbon (in the XVI to XVIII centuries) and Coimbra (XIX century). Finally, this finding highlights the need to study the entire series of mummified bodies in the Church of the Sacrament in order to compare the paleopathological findings and existing historical documents on syphilis, so as to expand the paleoepidemiological knowledge of this infection in XVIII century Lisbon.

Diptera Brachycera found inside the esophagus of a mummified adult male from the early XIX century, Lisbon, Portugal

Fly puparia and adult fragments of diptera muscid were found inside the esophagus of a mummified body from the early XIX century, buried inside the crypt of the Sacrament Church (Lisbon, Portugal). The identification of the material revealed a monospecific colonization by Ophyra capensis (Wiedemann) (Diptera: Muscidae), a species known to invade corpses in the ammoniacal fermentation wave. This species can be found in corpses kept indoors, not available to the early waves of blowflies (Diptera: Calliphoridae). In the present case, the number of pupae and their developmental stage suggest that the female invaded the mummified corpse through the partially opened mouth and the oviposition took place directly inside the esophagus. This is the first case of O. capensis infesting internal organs of an intact corpse. The use of chemical products for the embalming process probably explains why external colonization did not occur.

Air pollution and emergency admissions for cardiorespiratory diseases in Lisbon (Portugal)

Daily records of hospital admissions due to cardiorespiratory diseases and levels of PM10, SO2, CO, NO, NO2, and O3 were collected from 1999-2004 to evaluate the relationship between air pollution and morbidity in Lisbon. Generalised additive Poisson regression models were adopted, controlling for temperature, humidity, and both short and long-term seasonality. Significant positive associations, lagged by 1 or 2 days, were found between markers of traffic-related pollution (CO and NO2) and cardiocirculatory diseases in all age groups. Increased childhood emergency admissions for respiratory illness were significantly correlated with the 1-day lagged SO2 levels coming from industrial activities.

Outdoor/indoor air quality in primary schools in Lisbon: a preliminary study

Simultaneous measurements of outdoor and indoor pollution were performed at three schools in Lisbon. Volatile organic compounds (VOCs), formaldehyde and NO2 were passively monitored over a two-week period. Bacterial and fungal colony-forming units and comfort parameters were also monitored at classrooms and playgrounds. The highest indoor levels of CO2 (2666 μg/m³), NO2 (40.3 μg/m³), VOCs (10.3 μg/m³), formaldehyde (1.03 μg/m³) and bioaerosols (1634 CFU/m³), and some indoor/outdoor ratios greater than unity, suggest that indoor sources and building conditions might have negative effects on air indoors. Increasing ventilation rates and use of low-emission materials would contribute towards improving indoor air quality.

Perspectives on access to in vitro fertilization in Portugal

OBJECTIVE: To analyze users' reasons for choosing in vitro fertilization treatment in public or private services and to identify their suggestions for improving fertility treatment. METHODS: A qualitative study using an interpretative approach was conducted. Fifteen semi-structured interviews were conducted with patients undergoing in vitro fertilization treatment (nine women, one man and five couples) at home or at their workplace in the districts of Viana do Castelo, Braga, Porto and Lisbon, Portugal, between July 2005 and February 2006. RESULTS: Users evaluated access to in vitro fertilization treatment in public and private services based mainly on their individual experiences and called for more access to less costly, faster and friendlier care with suitable facilities, appropriate time management and caring medical providers. These perceptions were also associated with views on the need for fighting stigmatization of infertility, protecting children's rights and guaranteeing sustainability of health care system. Interviewees sought to balance reduced waiting time and more attentive care with costs involved. The choice of services depended on the users' purchase power and place of residence and availability of attentive care. CONCLUSIONS: Current national policies on in vitro fertilization treatment meet user's demands of promoting access to, and quality, availability and affordability of in vitro fertilization treatment. However, their focus on legal regulation and technical-scientific aspects contrasts with the users' emphasis on reimbursement, insurance coverage and focus on emotional aspects of the treatment. The study showed these policies should ensure insurance coverage, participation of user representatives in the National Council for Assisted Reproductive Technology, promotion of infertility research and certification of fertility laboratories.
