Political analysis of the neonatal screening for severe combined immunodeficiency - Curitiba, Brazil

Severe Combined Immunodeficiency (SCID) is the most aggressive form of primary immunodeficiencies, being able to death within 2 years after birth. In the USA, the screening found that the incidence of SCID was double that previously stipulated, before screening. Israel, Taiwan, Spain and others European countries are also testing for SCID. The long-term survival of patients diagnosed and treated before 4 months of life reaches 94%. Brazil does not perform neonatal screening for SCID through the Public Health System (SUS), numbers are unknown and under-diagnosed, even the treatment for SCID is funded by SUS. Analyze the political dimensions of the bill that aims to implement neonatal screening for SCID in Curitiba, Brazil. Participatory research was carried out between March - October 2019 and, bibliographic research on policy analysis in the context of emerging countries, to understand the criteria are taken into account for the political agenda, the influence of interest groups and the influence of the political arena in the implementation of a public policy through policy analysis. The project is pending in the municipal legislature of Curitiba and faces issues related to the financing of the implementation - a wide range of dependent variables act in the construction of a public policy. Its materialization, although important for public health, must consider real possibilities of implementation. In parallel, independent of the bill, a screening pilot project is under preparation by doctors, academics, and civil society. Brazil has a feasible technique that can be implemented on a large scale for neonatal SCID screening. However, although strongly recommended by the medical community, the implementation of this policy can be unviable by political and financial issues.

Key messages

The implementation of a public policy involves decisions between institutions, rules of the game and political forces. Early diagnosis may reduce treatment costs, requiring public policies for SCID.

Concomitant Malignant Pulmonary Peripheral Nerve Sheath Tumour and Benign Cutaneous Peripheral Nerve Sheath Tumour in a Dog

Peripheral nerve sheath tumours (PNSTs) are neoplastic growths derived from Schwann cells, perineural cells or both. Malignant PNSTs (MPNSTs) are uncommon in domestic animals. This report describes the concomitant occurrence of PNSTs in a 10-year-old female cocker spaniel with a clinical history of respiratory impairment. Grossly, there was a large infiltrative mass in the caudal lobe of the right lung; smaller nodules were observed in the other lobes of the right lung. Furthermore, a small encapsulated cutaneous nodule was observed on the left hindlimb. Histopathology of the pulmonary tumours revealed the proliferation of pleomorphic spindle-shaped cells with moderate mitotic index arranged in interwoven bundles and concentric Antoni A and Antoni B patterns; invasion of the adjacent pulmonary tissue was observed. The cutaneous nodule consisted of neoplastic mesenchymal cells in interwoven bundles with concentric whorls, but without the marked anisokaryosis, binucleation and infiltrative growth seen in the pulmonary tumour. Immunohistochemistry revealed that both tumours were immunoreactive for vimentin, glial fibrillary acidic protein and S100 protein, but were negative for factor VIII. These findings are indicative of a MPNST in the lung with a concomitant benign PNST in the limb. This case represents the first report of a primary MPNST in the lung of a dog. This neoplastic growth should be included in the differential diagnosis of primary malignant pulmonary tumours of dogs.
