- Adenocarcinoma do Íleon. Uma Entidade Rara e de Diagnóstico TardioPublication . Nabais, C; Salústio, R; Bispo, C; Sousa, F; Porto, E; Cardoso, C; Silva, G; Caldeira Fradique, AINTRODUÇÃO A neoplasia do intestino delgado é uma entidade rara, apresentando uma incidência anual de cerca de 2.1 casos por 100,000 pessoas, sendo o adenocarcinoma, o segundo tipo histológico mais frequente (em 33% dos casos). A localização distal deste tipo de tumor é menos habitual, o que torna o adenocarcinoma do íleon num evento invulgar. A raridade deste tipo de patologia, associada a uma apresentação clínica pouco específica, origina habitualmente um atraso no diagnóstico e tratamento. CASO CLÍNICO Doente de 66 anos admitida no S.U. com quadro de dor abdominal localizada na fossa ilíaca direita com cerca de 6 dias de evolução e agravamento progressivo. Anorexia, náuseas e vómitos no dia de admissão. Empastamento doloroso à palpação na fossa ilíaca direita. Exames complementares revelaram tumor inflamatório do apêndice ileocecal. Intraoperatoriamente constatou-se neoformação com envolvimento do apêndice ileocecal, cego e segmento de íleon distal. Adenopatias na raíz do mesentério. Optou-se pela realização de hemicolectomia direita com ressecção em bloco de íleon distal. O resultado histológico revelou adenocarcinoma do íleon, que se estendia ao apêndice ileocecal e condicionando apendicite aguda (pT4N0). DISCUSSÃO/CONCLUSÃO Este caso apresenta uma patologia pouco frequente, caracterizada por um diagnóstico tardio e de difícil realização. Sublinhamos neste trabalho, a importância de um diagnóstico mais precoce e um tratamento adequado, de forma a obter um aumento da taxa de sobrevivência destes doentes.
- Adenocarcinoma of the Ileum: A Rare and Challenging EntityPublication . Nabais, C; Salústio, R; Sousa, F; Porto, E; Cardoso, C; Caldeira Fradique, AINTRODUCTION: Primary small bowel malignancy is unusual and accounts for 1-3% of all gastrointestinal tract neoplasms. Adenocarcinoma is one of the most common histologic types, but its frequency decreases with more distal locations. Its clinical presentation is nonspecific and is usually associated with advanced disease, which contributes to delayed diagnosis. PRESENTATION OF CASE: A 66-year-old woman was admitted to the hospital with a 6-day history of progressively worsening abdominal pain localized in the right lower quadrant, nausea, and vomiting. Investigation revealed an inflammatory appendiceal tumor. The patient underwent surgery and an unexpected tumor involving the distal ileal segment and ileocecal appendix was found. Right radical hemicolectomy with en bloc resection of the distal ileum was performed. Histopathological examination revealed adenocarcinoma of the ileum. DISCUSSION: This rare entity is associated with a nonspecific clinical presentation that contributes to delayed diagnosis and treatment, and consequently to a worse prognosis. Approximately half of the cases are only diagnosed at surgery. Primary treatment consists of wide resection with locoregional lymphadenectomy. The role of adjuvant chemotherapy has yet to be determined. CONCLUSION: This case demonstrates an unusual condition characterized by late and challenging diagnosis. We highlight the importance of an earlier diagnosis and optimal treatment for improved patient outcomes.
- Essure®: Effectiveness, Complications and Satisfaction in 13 Years of ExperiencePublication . Félix, N; Carvalho, C; Isidro Amaral, P; Sousa, F; Delgado, E; Machado, AI; Mira, ROverview and aims: Female sterilization is the most used contraceptive method in the world. The hysteroscopic route is especially attractive for women at high surgical and anesthetic risk. Publications worldwide reported several possible adverse events, doubting the safety of the method. The objectives of this study are to evaluate the technical difficulties and complications, the adverse events in the short and long term, the effectiveness of the method and satisfaction. Study design: Retrospective cohort study. Population: A total of 105 women undergoing hysteroscopic sterilization with Essure® between 2005 and 2017 (13 years of study). Methods: The epidemiological and procedural data were accessed by consulting the clinical processes the family planning appointments. Long term follow-up was evaluated by telephone contact of all the women, with success in 68 cases. Results: The mean age was 38 years (SD 4,7). The procedure was successful in the first attempt in 99% (n=67) cases, the main technical difficulty identified was the permeabilization of the internal cervical os (8.6%; n=6) and the only intercurrence documented was vasovagal reaction (4.8%; n=3). The mean immediate pain post procedure was 4 (numeric pains cale, SD 2). Long term complications identified were: 1.5% (n=1) migration, 1.5% (n=1) partial unilateral expulsion, 4.4% (n=3) gynecological reoperation, 9% (n=7) headache, 11.8% (n=8) weight gain, 22.1% (n=15) chronic pelvic pain and 24.6% (n=17) abnormal uterine hemorrhage. There were no cases of pregnancy or allergic reaction. Most women were very or completely satisfied and would advise Essure® as a contraceptive method, 94% (n=64) and 97.1% (n=66) respectively. Conclusions: Hysteroscopic sterilization was highly effective and associated with low and mild difficulties and acute complications. Most women were satisfied with the method and long term adverse effects identified are difficult to promptly associate with Essure® since their high frequency in the peri-menopause, forcing more studies.
- Exposições Acidentais na Alergia AlimentarPublication . Antunes, J; Sousa, F; Paes, MJ; Chambel, M; Prates, S; Leiria-Pinto, PIntrodução: A recomendação habitual no tratamento da alergia alimentar é a evicção completa, até à aquisição de tolerância. É importante perceber em que situações ocorrem falhas na evicção, de forma a orientar o melhor possível o doente com alergia alimentar. Objectivo: Conhecer a frequência e caracterizar as exposições acidentais, num grupo de doentes com alergia alimentar. Material e métodos: A partir dos registos do Serviço de Imunoalergologia do Hospital Dona Estefânia, foram seleccionados doentes com idade ≤ 10 anos com alergia às proteínas do leite de vaca, ovo, peixe, amendoim ou frutos secos. Os pais/prestadores de cuidados responderam a um inquérito telefónico referente ao alimento implicado, falhas na dieta e sintomas. Resultados: Contactou -se um grupo de 65 doentes com idade média de 4,3 anos (63% do sexo masculino), totalizando 69 casos de alergia alimentar – cerca de 42 casos de alergia ao leite, 11 casos de alergia ao peixe, 10 de alergia ao ovo, 5 de alergia aos frutos secos e 1 de alergia ao amendoim. Na maioria dos casos a primeira reacção foi desencadeada por ingestão (95,6%) e foi imediata (78,3%), manifestando -se por sintomas mucocutâneos (MC) em 75,4%, gastrintestinais em 33,3% e respiratórios em 23,2%. Ocorreu anafilaxia em 17%. Houve falhas na dieta em 68,1% dos casos, que contabilizaram um total de 68 eventos de exposição acidental, na maioria (87,1%) com sintomas. Destes 68 eventos de exposição acidental, em 69,1% (n=47) o leite foi o alimento implicado, em 14,7% (n=10) foi o ovo, em 13,2% (n=9) o peixe e em 2,9% (n=2) os frutos secos. As manifestações clínicas mais frequentes foram MC (55,9,9%), seguindo -se as do tracto respiratório (25%) e as do tracto gastrointestinal (23,5%). Em 20,5% dos eventos de exposição acidental, ocorreu reacção anafiláctica. A maior parte das ingestões/exposições acidentais ocorreram em casa (36,8%) e na escola (29,4%). Perante a reacção foi administrada terapêutica em 41,2%, aguardaram resolução espontânea 38,2% e recorreram ao serviço de urgência 20,6% dos casos. Conclusões: As falhas na dieta de evicção foram frequentes, a maioria com sintomas. Aconteceram maioritariamente em casa e na escola, o que pode sugerir lacunas no conhecimento dos pais/prestadores de cuidados. A caracterização das exposições acidentais nos doentes com alergia alimentar poderá ajudar a optimizar a transmissão de informação, a estes e aos seus responsáveis, relativamente à prevenção de situações de risco.
- Late Onset Neuromyelitis Optica Spectrum Disorders (LONMOSD) from a Nationwide Portuguese Study: Anti-AQP4 Positive, Anti-MOG Positive and Seronegative SubgroupsPublication . Santos, E; Moura, J; Samões, R; Sousa, AP; Mendonça, T; Abreu, P; Guimarães, J; Correia, I; Durães, J; Sousa, L; Ferreira, J; de Sá, J; Sousa, F; Sequeira, M; Correia, AS; André, AL; Basílio, C; Arenga, M; Brás Marques, I; Perdigão, S; Alves, I; Santos, M; Salgado, V; Palos, A; Guerreiro, R; Isidoro, L; Boleixa, D; Carneiro, P; Neves, E; Martins Silva, A; Gonçalves, G; Sá, MJIntroduction: Several neuroimmunological disorders have distinct phenotypes according to the age of onset, as in multiple sclerosis or myasthenia gravis. It is also described that late onset NMOSD (LONMOSD) has a different phenotype. Objective: To describe the clinical/demographic characteristics of the LONMOSD and distinguish them from those with early onset (EONMOSD). Methods: From a nationwide Portuguese NMOSD study we analyzed the clinical/demographic characteristics of the LONMOSD. Results: From the 180 Portuguese patients 45 had disease onset after 50 years old, 80% were female. 23 had anti-AQP4 antibodies (51.1%), 13 anti-MOG antibodies (28.9%) and 9 were double seronegative (20.0%). The most common presenting phenotypes in LONMOSD were transverse myelitis (53.3%) and optic neuritis (26.7%), without difference from EONMOSD (p = 0.074). The mean EDSS for LONMOSD was 6.0 (SD=2.8), after a mean follow-up time of 4.58 (SD=4.47) years, which was significantly greater than the mean EDSS of EONMOSD (3.25, SD=1.80)(p = 0.022). Anti-AQP4 antibodies positive LONMOSD patients had increased disability compared to anti-MOG antibodies positive LONMOSD (p = 0.022). The survival analysis showed a reduced time to use a cane for LONMOSD, irrespective of serostatus (p<0.001). Conclusions: LONMOSD has increased disability and faster progression, despite no differences in the presenting clinical phenotype were seen in our cohort.

- McCune Albright Syndrome: A Diagnosis to be Kept in MindPublication . Barros, L; Sousa, F; Bernardo, MJPrecocious puberty, defined as the development of secondary sexual characteristics before the age of 8, often leads to anxiety in patients and their families but also in clinicians searching for the final diagnosis. After adequate investigation, the majority of the cases in girls turn out to be idiopathic. The authors present a case of McCune Albright syndrome in order to call attention to a rare cause of sexual precocity and the value of ultrasound in the evaluation of these situations. 10 years old infant girl admitted in our department due to irregular menstrual bleeding. She experienced a vaginal bleeding by the age of 3 which led to the diagnosis of McCune Albright Syndrome after a complete evaluation. Pubertal assessment revealed a reversed sequence in the remaining events with adrenarche at 5 and thelarche at 8. Hormonal evaluation demonstrated low FSH and LH levels (11,2 and 6,72 respectively) with high estrogen (204). Pelvic ultrasound showed a normal sized uterus (73x 29x32 mm), endometrial thickness of 5 mm and ovaries with several microfollicles and a copus luteum measuring 23 mm in the right ovary. McCune Albright syndrome is a very uncommon cause of sexual precocity that should, however, be suspected in all infant girls who present with vaginal bleeding. It is characterized by a triad: polyostotic fibrous dysplasia, gonadotropin-independent precocious puberty and café-au-lait skin spots. Due to autonomous production of estrogen by the ovaries, ultrasound image of the female reproductive tract is inconsistent with chronologic age. Pelvic ultrasound demonstrates a normal sized uterus with a well defined cervix and clearly identified ovaries with several follicles, similar to adult women of reproductive age. Ultrasonography of the pelvis has also an important role excluding other causes of GnRH-independent precocious puberty conditions like ovarian cysts or tumors.
- Neuromyelitis Optica Spectrum Disorders: a Nationwide Portuguese Clinical Epidemiological StudyPublication . Santos, E; Rocha, AL; Oliveira, V; Ferro, D; Samões, R; Sousa, AP; Figueiroa, S; Mendonça, T; Abreu, P; Guimarães, J; Sousa, R; Melo, C; Correia, I; Durães, J; Sousa, L; Ferreira, J; Sá, J; Sousa, F; Sequeira, M; Correia, AS; André, AL; Basílio, C; Arenga, M; Mendes, I; Brás Marques, I; 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; Martins Silva, A; 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.
- Office Hysteroscopy After Ultrasonographic Diagnosis of Thickened Endometrium in Postmenopausal PatientsPublication . Cordeiro, A; Condeço, R; Leitão, C; Sousa, F; Coutinho, S; Silva, MC; Bernardo, MJ; Mira, RThe aim of our study was to access office hysteroscopy results in postmenopausal patients with thickened endometrium. A retrospective descriptive study was carried out on 245 postmenopausal patients submitted to office hysteroscopy after sonographic diagnosis of thickened endometriumin 20 consecutive months.Women were evaluated for age, hormonal therapy, hysteroscopic findings, procedure duration, complications and associated pain, and histological diagnosis. Patients with and without uterine bleeding were considered separately. Symptomatic patients were older and had longer procedure duration. The most frequent hysteroscopic finding was endometrial polyp in both groups. Pain was subjectively assessed in a numeric scale from 0 to 10 and median value was 4. There were no complications reported. Global neoplasia rate was 2.9% for asymptomatic patients and 16.4% for symptomatic ones (p<0.05). Thickened endometrium with postmenopausal metrorrhagia gave patients a significantly higher risk for neoplasia and hyperplasia.
- Problemas Ginecológicos em Adolescentes com Patologia NeurológicaPublication . Silva, F; Sousa, F; Calado, EIntrodução: A contracepção e os problemas ginecológicos em adolescentes com patologia neurológica tem uma abordagem geral comum ao grupo etário. Contudo, algumas patologias como a epilepsia e o défice cognitivo (DC) profundo determinam necessidades e desafios adicionais emalguns casos. Objectivos: Caracterizar as necessidades e os problemas ginecológicos e respectivas opções terapêuticas em dois grupos de adolescentes com doença neurológica, com e sem DC. População e Métodos: Revisão casuística das adolescentes referenciadas da Consulta de Neuropediatria para a Consulta de Ginecologia de um hospital materno-infantil entre Janeiro de 1998 e Maio de 2007. Resultados: Foram identificadas 57 referenciações de adolescentes,37 com défice cognitivo (65%) e 20 sem défice cognitivo (DC). O DC foi classificado como “limiar” (1),ligeiro (7), moderado (8) ou grave/profundo (21). O segundo diagnóstico mais frequente foi a epilepsia (54% no grupo com DC e 60% no grupo sem DC). A contracepção foi motivo de consulta em 65% dos casos de cada grupo. Em doze adolescentes, foi utilizado o implante hormonal subcutâneo(10 com DC), e dez iniciaram contracepção oral (4 com DC). Não houve diferenças na opção por método hormonal em função da existência ou não de epilepsia (p=0,54). A dismenorreia foi a queixa ginecológica mais frequente em ambos os grupos (N=12). Seis adolescentes com DC profundo foram esterilizadas por necessidade de contracepção e/ou dismenorreia intensa, menorragia ou dificuldades com a higiene menstrual, incluindo quatro laqueações tubárias laparoscópicas, duas histerectomias supracervicais e duas histerectomias totais. Conclusões: A epilepsia não impede a contracepção hormonal em grande parte dos casos. O implante subcutâneo ultrapassa a dificuldade na adesão à contracepção oral em jovens com DC. Existem questões éticas e legais associadas à esterilização de adolescentes com DC profundo.
