Characteristics and management of mirror syndrome: a systematic review (1956-2016).

OBJECTIVES: To describe the clinical features of mirror syndrome and to correlate the effects of different treatments with the fetal outcomes. DATA SOURCES: Online search up to May 2016 was conducted in the PubMed, Embase (Ovid platform) and clinicalTrials.gov without restrictions of language, date or journal. Only papers providing both fetal and maternal presentations and outcomes were included. RESULTS: The study included 74 papers (n=111), with an additional two patients diagnosed at our center (n=113). The mean gestational age at diagnosis was 27 weeks±30 days (16-39 weeks). Whether early or late gestational age at diagnosis, and whether mother and fetus show symptoms simultaneously or on different dates, has insignificant impact on fetal outcome (P=0.06 and P=0.46, respectively). Edema (84%) followed by hypertension (60.1%) were the leading maternal findings. Fetal hydrops (94.7%) and placental edema (62.8%) were the commonest sonographic features. Procedures correcting fetal hydrops/anemia in utero as well as labor induction were the only treatment options correlated with improved fetal survival (χ2 analysis, P=0.01 and Fisher's exact test, P=0.02; respectively). The overall rate of fetal/neonatal mortality was 67.26%. CONCLUSION: The gestational age at diagnosis and sequence of presentation have insignificant impact on fetal outcome. Improved fetal survival was associated with procedural interventions that correct fetal hydrops as well as labor induction.

Atypical Presentation of Pigmented Villonodular Synovitis: A Case Report.

Pigmented villonodular synovitis is a rare, disabling disease that usually presents in young adults. Here, the authors present a unique case of pigmented villonodular synovitis in a 60-year-old female diagnosed 20 years after the initial presentation. The patient presented with a complaint of knee pain consistent with osteoarthritis. Radiological investigations, including magnetic resonance imaging, only showed degenerative changes and were inconclusive to diagnose pigmented villonodular synovitis. Intraoperative macroscopic features of the synovium suggested pigmented villonodular synovitis, which was confirmed by histopathological examination. Histopathological examination, despite being the gold standard, was performed late in this case. The authors recommend histopathological confirmation of pigmented villonodular synovitis in all suspected cases, even with inconclusive radiological manifestations.
