Results from studies evaluating potential effects of prenatal exposure to radio-frequency electromagnetic fields from cell phones on birth outcomes have been inconsistent. Using data on 55,507 pregnant women and their children from Denmark (1996–2002), the Netherlands (2003–2004), Spain (2003–2008), and South Korea (2006–2011), we explored whether maternal cell-phone use was associated with pregnancy duration and fetal growth. On the basis of self-reported number of cell-phone calls per day, exposure was grouped as none, low (referent), intermediate, or high. We examined pregnancy duration (gestational age at birth, preterm/postterm birth), fetal growth (birth weight ratio, small/large size for gestational age), and birth weight variables (birth weight, low/high birth weight) and meta-analyzed cohort-specific estimates. The intermediate exposure group had a higher risk of giving birth at a lower gestational age (hazard ratio = 1.04, 95% confidence interval: 1.01, 1.07), and exposure-response relationships were found for shorter pregnancy duration (P < 0.001) and preterm birth (P = 0.003). We observed no association with fetal growth or birth weight. Maternal cell-phone use during pregnancy may be associated with shorter pregnancy duration and increased risk of preterm birth, but these results should be interpreted with caution, since they may reflect stress during pregnancy or other residual confounding rather than a direct effect of cell-phone exposure.

Background: Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a rare congenital syndrome characterized by uterovaginal agenesis. Most patients are diagnosed during adolescence, when body image and sexual identity are shaped. Our main objective was to investigate how MRKH syndrome affects psychology, quality of life (QoL), and the sexual life of patients compared with non-affected individuals. Methods: Original peer-reviewed research papers examining psychological outcomes, QoL, and sexual function of MRKH patients were searched in PubMed. Titles, abstracts, and full text from potentially eligible records were reviewed by two independent reviewers. Case reports and papers published not in English were excluded. Results: Our search identified 63 records, of which 20 were included: 10 examined psychological and psychosocial outcomes, 14 examined sexual function outcomes, and 6 examined QoL outcomes. Results may be affected by selection bias and confounding due to differences between MRKH patients and controls. Conclusions: MRKH could be associated with a higher prevalence of anxiety and depression symptoms and social insecurity compared with women of a similar age without the condition. MRKH could also be associated with greater pain and discomfort during sexual intercourse and limitations in arousal, lubrication, and orgasm. MRKH patients more commonly experience impairment of mental-health-related QoL, but physical-health-related QoL is not affected.

Fibroadenomas are common benign breast tumors. Fibroadenomas that exceed 5 cm in diameter, weigh more than 500 g, or replace more than four-fifths of the breast are characterized as giant. A fibroadenoma diagnosed in patients during childhood or adolescence is characterized as juvenile. An extensive PubMed search of the literature in English up until August 2022 was performed. In addition, a rare case of a gigantic fibroadenoma in an 11-year-old premenarchal girl who was referred to our adolescent gynecology center is presented here. Eighty-seven cases of giant juvenile fibroadenomas have been reported in the literature along with our case. Patients with giant juvenile fibroadenoma presented at a mean age of 13.92 years and usually after menarche. Juvenile fibroadenomas are usually unilateral, occurring either in the right or the left breast; the majority of them are diagnosed when they are already more than 10 cm in size, and they are most frequently treated with total lump excision. Differential diagnosis includes phyllodes tumors and pseudo-angiomatous stromal hyperplasia. Conservative management is feasible, but surgical excision is recommended to patients with suspicious imaging features or when the mass grows rapidly.
