Maternity blues in Athens, Greece: a study during the first 3 days after delivery.

BACKGROUND: Although maternity blues have been studied in many countries worldwide the factors that influence the occurrence of this clinical entity are not well understood. The purpose of this study was to investigate the prevalence, time course and symptomatology of maternity blues in a Greek urban environment as well as the relation of maternity blues with certain clinical and sociodemographic factors. METHOD: A study of a sample of 402 women that were recruited during the first day after delivery. Each woman completed the Kennerley's Blues Questionnaire on a daily basis for the first 3 days of puerpartum. Clinical and sociodemographic data were obtained through questionnaires and personal interview. RESULTS: 179 (44.5%) women experienced severe maternity blues during the first 3 days after delivery. Delivery by caesarian section (P=0.006), stressful events during pregnancy (P=0.02), depressive feelings the last month prior to delivery (P=0.002), anxiety on the day of delivery (P=0.001) and hypochondriasis (P=0.001) were the factors that were found to relate significantly to maternity blues. CONCLUSION: The women's emotional condition prior and after delivery, delivery via caesarotomy, as well as fears concerning somatic health had strong impact on the occurrence of maternity blues.

Ovarian masses in young adolescents: imaging findings with surgical confirmation.

Functional cysts and benign neoplasms are the most common ovarian masses among young adolescents. Ovarian cancer on the other hand, although rare in this age group, is the most common genital tract malignancy. The purpose of this study was to define imaging characteristics of ovarian masses in adolescents between 12 and 21 years old and correlate imaging and surgical findings. Thirty-seven female adolescent patients aged between 12 and 21 years were operated on because of a diagnosed ovarian mass between 1997 and 2002. All patients underwent pelvic ultrasound, five had an abdominal CT scan, two had abdominal MRI, one abdominal X-ray and one intravenous pyelography. Ultrasound was used to define the size of the lesion and to characterize its gross morphologic condition as solid, simple cyst or complex cyst. The records were reviewed for age at presentation, presenting symptoms, diagnostic studies, surgical procedure and pathology findings, which were available for all patients. In our study 32 patients (86.5%) were symptomatic and five asymptomatic (13.5%). The most common presenting symptom was abdominal pain (59.5%). Thirty-four patients (91.1%) had benign lesions, two had malignant tumors (5.4%) and one patient had a borderline lesion (2.7%). The most common ovarian masses detected were germ cell tumors (27.5%) and functional cysts (25%). Twenty patients (54%) underwent operative laparoscopy and 17 patients (46%) exploratory laparotomy. Simple resection of the ovarian mass was achieved in the majority of cases (84%). Bilateral salpingo-oophorectomy was performed in only one case (2.7%).

A tragic case of complicated labour in early Byzantium (404 A.D.).

OBJECTIVES: Presentation and comment on the problematic delivery of the Byzantine empress Eudoxia's stillborn child. STUDY DESIGN: The original Greek language Byzantine histories, chronicles and hagiographical sources were investigated. Comparisons were then made of the knowledge of obstetrics among contemporary and ancient physicians. RESULTS: The case of Eudoxia's delivery is described in various literary sources with details regarding the fatal clinical picture of the parturient after the embryo's death. The study of early and contemporary medical texts proves that in similar cases conservative treatment was preferred but embryotomy was followed in the event of failure. CONCLUSIONS: Eudoxia's labour represents a characteristic paradigm of the difficulties involved in the confrontation of complicated deliveries in mediaeval times, often resulting in the death of both the mother and embryo. The treatments follow the ancient Hippocratic, Hellenistic and Roman traditions and influence medieval European medicine, thus constituting significant roots of obstetrics.

TCRgammadelta + T lymphocytes in unexplained recurrent spontaneous abortions.

PROBLEM: It is generally accepted that the immune system and cellular immunity in particular are involved in the mechanisms affecting the outcome of gestation. In order to evaluate a putative role of lymphocytes in the immunological mechanisms of unexplained recurrent spontaneous abortions (URSA), we studied peripheral blood lymphocyte subpopulations in 244 women with URSA and 44 controls. METHOD OF STUDY: Direct immunofluorescence in whole blood with the appropriate combinations of monoclonal antibodies and flow cytometry was used. RESULTS: The study showed: a) a statistically significant increase of the mean CD4/CD8 ratio (2.12+/-0.84 vs 1.85+/-0.63, P = 0,039); b) a statistically significant decrease of the mean value of the percentage of CD5+ CD19+ lymphocytes (0.4+/-0.6 vs 1.4+/-0.78, P < 0.0001); and c) a statistically significant increase of the percentage of T lymphocytes expressing TCRgammadelta (4.68+/-3.19 vs 2.61+/-1.14, P < 0.0001). It should be noted that a statistically significant high number of women with URSA (72/195, 36.9%) showed an increased percentage of TCRgammadelta T cells (> or = 5%, where 5 equals the mean value + 2 standard deviations (SD) of the mean value of controls), whereas such a high percentage was not found in any control subject. CONCLUSIONS: It seems that women who experienced URSA comprise a heterogeneous population, as far as immunological parameters are concerned. At least in a subgroup of them, TCRgammadelta + T cells could be considered to play a role in the immune pathogenesis of fetal loss.
