Tipos Polínicos Alergizantes em Portugal – Calendário de 2002-2004

Os calendários polínicos constituem instrumentos fundamentais para a orientação clínica de doentes alérgicos. Em Portugal, a sua elaboração de forma sistematizada teve início em 2002. Para tal foram colocados polinómetros volumétricos Burkard em cinco cidades do país: Porto, Coimbra, Lisboa, Évora e Portimão. O registo das contagens foi efectuado por método estandardizado. As contagens polínicas diárias expressam a concentração média por m3. Estas contagens foram objecto de análise descritiva e comparativa. O período de incidência polínica máxima decorre entre Março e Julho, sendo o pólen de Poaceae e de ervas silvestres os mais frequentemente identificados. Em Janeiro, Fevereiro e Dezembro existem níveis elevados de pólen de árvores em todo o território nacional. O Sul do país apresenta indicadores de polinização mais intensa.

Trombocitopénia e Gravidez. A Propósito de um Caso Clínico

A trombocitopenia é a alteração hemostática mais frequente na gravidez, sendo mais comum no IIIº trimestre ou intra parto. É um sinal de uma anomalia coincidente ou provocada pela gravidez com diferentes graus de gravidade. Daí a necessidade de um diagnóstico correcto destas situações. A propósito de vários casos de trombocitopenia ocorridos no Serviço de Medicina Materno-Fetal da MAC e após revisão bibliográfica, os autores propuseram a elaboração de um protocolo de diagnóstico e de terapêutica destas situações na gravidez.

Office Hysteroscopy After Ultrasonographic Diagnosis of Thickened Endometrium in Postmenopausal Patients

The 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.

Paludismo e Gravidez

O paludismo é uma das doenças infecciosas mais importantes no mundo, particularmente nas regiões tropicais. É uma doença grave, que quando não diagnosticada e tratada correctamente, pode ser mortal. A grávida apresenta maior risco de morbimortalidade, estando o paludismo associado a aborto, parto pré-termo (PPT) e atraso de crescimento intra-uterino (ACIU). Apesar de estar erradicado em Portugal, ocorreram no ano de 1997 vários casos de internamento por paludismo, no Serviço de Medicina Materno-Fetal da Maternidade Dr. Alfredo da Costa, tratando-se sempre de grávidas oriundas de regiões endémicas. Os autores fazem uma revisão teórica sobre a etiologia, epidemiologia, fisiopatologia, clínica, consequências para a gravidez, diagnóstico, terapêutica e profilaxia para esta doença.

Torpedo Maculopathy with an Anisometropic Amblyopia in a 5-Year-Old Caucasian Girl: Case Report

The aim of this study is to report a clinical case of asymptomatic female Caucasian children with torpedo maculopathy. A 5-year-old girl was referred to our clinic for routine evaluation. The ophthalmic examination revealed best-corrected visual acuity of 20/20 in both eyes, without any changes in the biomicroscopy. Fundus examination showed normal findings in one eye, whereas in the contralateral eye it disclosed, in the temporal sector of the macular region, a whitish, atrophic, oval chorioretinal lesion with clearly defined margins. Posterior evaluations documented the stability of the lesion. Torpedo maculopathy diagnosis is based on its characteristic shape and peculiar location. The differential diagnosis has to be established versus choroidal lesions (melanoma and nevus), congenital or iatrogenic hyperplasia of the retinal pigment epithelium (RPE) and particularly versus the congenital pigmented lesions associated with Gardner's syndrome.

Ovarian Borderline Tumor and Fertility-Sparing Surgery

Ovarian borderline tumors (OBTs) are frequently diagnosed in women of reproductive age. There is no consensus about their management, and it sometimes represents a dilemma aboutwhat should be done: fertility sparing surgery or a hysterectomy with salpingo-oophorectomy? Case: A 32-year-old nulligravida, diagnosed with a right ovarian borderline tumor is presented. She underwent pelvic washings, right salpingo-oophorectomy, appendectomy, and omental and peritoneal biopsies (laparotomic approach). Macroscopically, the left ovary was normal and subsequent exploration for staging was also normal, including the lymph nodes. Intraoperatively, frozen section examination was unclear, suggesting an OBT. Results: The final histopathologic diagnosis was ovarian borderline tumor, stage IIC (International Federation of Gynecology and Obstetrics [FIGO] staging). The patient expressed a desire to preserve her fertility. Thirty-six months postsurgery, she became pregnant spontaneously and delivered a healthy newborn at term. Conclusions: Conservative surgery can be performed in young patients treated for an OBT, provided they are closely followed up and that this surgery is performed after careful consideration and informed consent. It is, however, controversial with respect to performing hysterectomy and salpingo-oopherectomy upon the patient’s completion of childbearing.
