The term Potter syndrome is most frequently associated with the condition of oligohydramnios sequence regardless of the root cause of the absence or reduced volume of amniotic fluid. However, as noted in this article, the term Potter syndrome was initially coined in order to refer to fetuses and infants with BRA. It was not until later that the term became more encompassing as it was noted that other causes of failed fetal urine production also resulted in similar physical characteristics and prognoses of the fetuses and infants with BRA (that which Potter originally described in 1946). Since then, the term Potter syndrome has become a misnomer and experts have attempted not to eliminate the terminology, but to modify it in a way so as to be able to determine the different root causes by creating a nomenclature system. However, this classification system has not caught on in the clinical and research fields. See also

Macrophagic myofasciitis (MMF) is a histopathological finding involving inflammatory microphage formations with aluminium-containing crystal inclusions and associated microscopic muscle necrosis in biopsy samples of the deltoid muscle. Based on the presence of aluminium and the common practice of administering vaccines into the deltoid, it has been proposed that the abnormalities are a result of immunisation with aluminium adjuvant-containing vaccines. The findings were observed in a minority of persons being evaluated for "diffuse myalgias, arthralgias or muscle weakness" who underwent deltoid muscle biopsies. The individuals had a history of receiving aluminium-containing vaccines, administered months to several years prior to observation of MMF histopathology, however this link is tenuous and unsustainable. It has been subsequently proposed that macrophagic myofasciitis is in fact a systemic disorder where various diseases develop in association and as consequence of vaccination with aluminium-containing vaccines in susceptible individuals, however, the World Health Organization has concluded that "[t]here is no evidence to suggest that MMF is a specific illness", and that "[t]he current evidence neither establishes nor excludes a generalized disorder affecting other organs." Description
MMF was first described in 1998 by a consortium of French myopathologists as an emerging condition of unknown cause characterised by a defining lesion observed upon muscle biopsy. MMF was identified in patients affected by myalgia and fatigue.
