- A Circuncisão Ritual e Correcção Plástica da FimosePublication . Leal, MJ; Mendes, JOs AA. descrevem duas variantes da sua técnica pessoal de plastia do prepúcio para tratamento da Fimose. Utilizam uma variante da técnica de Duhamel, incisando a face dorsal do prepúcio em S itálico nos casos em que o anel estenosante é moderado e permite um deslizamento com exposição da glande. Nos casos de Fimose muito acentuada ressecam ad minima o prepúcio e fazem uma plastia YV na face dosrsal e se necessário uma pequena excisão da pele ventral excedente. Em ambas as técnicas conseguem um bom resultado estético, muitos dos casos são difíceis de distinguir de um prepúcio normal. As plastias com conservação do prepúcio tendem a ser mais utilizadas na cultura europeia contemporânea, onde os motivos rituais desapareceram e os hábitos de higiene se instalaram. Salvo por motivos religiosos ou indicações médicas precisas (diabetes, lesões dermatológicas, etc) a correcção da Fimose por técnicas mutilantes tende a desaparecer.
- Incontinência Fecal. O que Fazer?Publication . Gonçalves, M; Mendes, J; Leal, MJVárias são as patologias orgânicas ou funcionais que podem interferir com os mecanismos da defecação. Os AA apresentam 4 casos clínico com incontinência fecal: - 1 falsa encoprese - 2 mielomeningocelos - 1 anastomsose ileo-anal (colectomia total em D. de Behçet). Todos os casos foram avaliados manométricamente, e operados com miorrafia dos levantadores do recto, plastia dos músculos glúteos, com aproximação e sutura mediana, sem dissecção circunferencial do recto, solidarizando músculos contíguos de inervação independente. Na incontinência por anastomose ileo-anal foi préviamente feita ileostomia e reconstruída uma bosa rectal. Nos outros casos não foi feita qualquer derivação intestinal. Em 3 casos os pós-operatórios decorreram sem incidentes tendo havido uma nítida melhoria da continência. No outro caso (mielomeningocelo) verificou-se uma complicação abcesso com deiscência de sutura - o que contribuiu muito provávelmente para um resultado menos satisfatório. Depois de claramente despistados os casos de incontinência, a técnica utilizada é de simples execução, usando para a reconstrução anatómica e funcional grupos musculares vizinhos capazes de melhorar os mecanismos de continência.
- Mitral Valve Myxomas: an Unusual EntityPublication . Oliveira, R; Branco, LM; Dias, L; Timóteo, AT; Patrício, L; Agapito, A; Robalo, F; Mendes, J; Pinto, E; Cruz Ferreira, RPrimary tumours of the heart are uncommon entities, cardiac myxomas being the most frequent. However, mitral valve myxomas are exceptionally rare. In the last 12 years, there have been 25 myxomas diagnosed at our institution, with only two of them originating from the mitral valve. Both patients were female, the first, 25, and the second, 72 years old. The younger patient was very symptomatic with a large mass, 4 cm long, which involved both leaflets causing significant obstruction to the left ventricular inflow. The second one had a smaller mass located at the atrial side of the posterior leaflet that only produced some flow divergence. Neither of them had constitutional nor embolic symptoms. Both patients were submitted to emergent surgical resection that in the first case involved the mitral valve and replacement with mechanical prosthesis. The macroscopic appearance of these tumours suggested a malignant aetiology which may represent somewhat different features of the myxomas when originating from the cardiac valves. Both patients are well reflecting the good prognosis of this illness after resection, although the younger patient was re-operated because of prosthetic valve obstruction and suspicion of recurrence that was not confirmed. Because of the illustrative images and different presentations, we found it interesting to report and discuss them together.
- Prostatic Arterial Embolization to Treat Benign Prostatic HyperplasiaPublication . Pisco, JM; Pinheiro, LC; Bilhim, T; Duarte, M; Mendes, J; Oliveira, APURPOSE: To evaluate whether prostatic arterial embolization (PAE) might be a feasible procedure to treat lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Fifteen patients (age range, 62-82 years; mean age, 74.1 y) with symptomatic BPH after failure of medical treatment were selected for PAE with nonspherical 200-μm polyvinyl alcohol particles. The procedure was performed by a single femoral approach. Technical success was considered when selective prostatic arterial catheterization and embolization was achieved on at least one pelvic side. RESULTS: PAE was technically successful in 14 of the 15 patients (93.3%). There was a mean follow-up of 7.9 months (range, 3-12 months). International Prostate Symptom Score decreased a mean of 6.5 points (P = .005), quality of life improved 1.14 points (P = .065), International Index of Erectile Function increased 1.7 points (P = .063), and peak urinary flow increased 3.85 mL/sec (P = .015). There was a mean prostate-specific antigen reduction of 2.27 ng/mL (P = .072) and a mean prostate volume decrease of 26.5 mL (P = .0001) by ultrasound and 28.9 mL (P = .008) by magnetic resonance imaging. There was one major complication (a 1.5-cm(2) ischemic area of the bladder wall) and four clinical failures (28.6%). CONCLUSIONS: In this small group of patients, PAE was a feasible procedure, with preliminary results and short-term follow-up suggesting good symptom control without sexual dysfunction in suitable candidates, associated with a reduction in prostate volume.
- Validation of the Telephone-Administered Version of the Mediterranean Diet Adherence Screener (MEDAS) QuestionnairePublication . Gregório, MJ; Rodrigues, AM; Salvador, C; Dias, S; Sousa, R; Mendes, J; Coelho, P; Branco, J; Lopes, C; Martínez-González, M; Graça, P; Canhão, HA 14-Item Mediterranean Diet Adherence Screener (MEDAS) questionnaire was developed and validated in face-to-face interviews, but not via telephone. The aims of this study were to evaluate the validity and reliability of a telephone-administered version of the MEDAS as well as to validate the Portuguese version of the MEDAS questionnaire. A convenience community-based sample of adults (n = 224) participated in a three-stage survey. First, trained researchers administered MEDAS via a telephone. Second, the Portuguese version of Food Frequency Questionnaire (FFQ), and MEDAS were administered in a semi-structured face-to-face interview. Finally, MEDAS was again administered via telephone. The telephone-administered MEDAS questionnaire was compared with the face-to-face-version using several metrics. The telephone-administered MEDAS was significantly correlated with the face-to-face-administered MEDAS [r = 0.805, p < 0.001; interclass correlation coefficient (ICC) = 0.803, p < 0.001] and showed strong agreement (k = 0.60). The MEDAS scores that were obtained in the first and second telephone interviews were significantly correlated (r = 0.661, p < 0.001; ICC = 0.639, p < 0.001). The overall agreement between the Portuguese version of MEDAS and the FFQ-derived Mediterranean diet adherence score had a Cohen's k = 0.39. The telephone-administered version of MEDAS is a valid tool for assessing the adherence to the Mediterranean diet and acquiring data for large population-based studies.
