- "Death by a thread" - Peritonitis due to visceral perforation by a guide wire, during proximal femur osteosynthesis with DHS: A fatal case and legal implications.Publication . Durão, C; Barros, A; Guerreiro, R; Pedrosa, FIatrogenic intestinal perforations in orthopaedic surgery are very rare. Reports of iatrogenic lesions caused by a guide wire during femur fracture osteosynthesis are even scarcer. There are no similar reports in recent literature. As opposed to what is normally described the lesion documented in this case report was not identified on time resulting in death by peritonitis. The forensic autopsy allowed the identification of an intestinal perforation with faecal leakage to peritoneal space in association with a vesical perforation enabling the reproduction of the guide wire path. In view of the increasing number of osteosynthesis it is essential for the surgeon to be aware of possible complications due to guide wire perforations. Cases like this go unnoticed if the forensic pathologist is not familiarized with the surgical technique which may explain the rarity of such descriptions in literature.
- Neuromyelitis optica spectrum disorders: A nationwide Portuguese clinical epidemiological studyPublication . Santos, E; Rocha, AL; Oliveira, V; Ferro, D; Samões, R; Sousa, P; Figueiroa, S; Mendonça, T; Abreu, P; Guimarães, J; Sousa, R; Melo, C; Correia, I; Durães, J; Sousa, L; Ferreira, J; de Sá, J; Sousa, F; Sequeira, M; Correia, AS; André, AL; Basílio, C; Arenga, M; Mendes, I; Marques, IB; Perdigão, S; Felgueiras, H; Alves, I; Correia, F; Barroso, C; Morganho, A; Carmona, C; Palavra, F; Santos, M; Salgado, V; Palos, A; Nzwalo, H; Timóteo, A; Guerreiro, R; Isidoro, L; Boleixa, D; Carneiro, P; Neves, E; Silva, AM; Gonçalves, G; Leite, MI; Sá, MJIntroduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients were included. Results: A total of 180 patients met the 2015 Wingerchuk NMOSD criteria, 77 were AQP4-antibody positive (Abs+), 67 MOG-Abs+, and 36 seronegative. Point prevalence on December 31, 2018 was 1.71/100,000 for NMOSD, 0.71/100,000 for AQP4-Abs+, 0.65/100,000 for MOG-Abs+, and 0.35/100,000 for seronegative NMOSD. A total of 44 new NMOSD cases were identified during the two-year study period (11 AQP4-Abs+, 27 MOG-Abs+, and 6 seronegative). The annual incidence rate in that period was 0.21/100,000 person-years for NMOSD, 0.05/100,000 for AQP4-Abs+, 0.13/100,000 for MOG-Abs+, and 0.03/100,000 for seronegative NMOSD. AQP4-Abs+ predominated in females and was associated with autoimmune disorders. Frequently presented with myelitis. Area postrema syndrome was exclusive of this subtype, and associated with higher morbidity/mortality than other forms of NMOSD. MOG-Ab+ more often presented with optic neuritis, required less immunosuppression, and had better outcome. Conclusion: Epidemiological/clinical NMOSD profiles in the Portuguese population are similar to other European countries.

- Ventilação Mecânica próximo dos Grandes Centros: Experiência de uma Unidade de Apoio PeriNatalPublication . Vale, P; Guerreiro, R; Luiz, P; Gonçalves, G; Areias, F; Nunes, A; Mocho, A; Garcia, P; Berdeja, A; Avelar, CA retrospective study of the newborns who were submitted to mechanical ventilation at the Neonatal Intermediate Care Unit was made between July 1991 and June 1994. Mechanical ventilation in such a unit should be transitory and not exceed 24 hours. Information concerning pregnancy, labour, neonates, type of ventilation and its problems was gathered. Forty seven neonates were ventilated. The average ventilation time was six hours (1-20 hours). The main cause of ventilation was hyaline membrane disease which occurred in 24% of all cases. Mortality observed was 16.6% and some sequellae were registered which were related not only to ventilation but also to the basic pathology in 26% of cases.
