Melamine Poisoning Pediatric Urolithiasis Treatment in Gansu, China 5-Year Follow-up Analysis

Urolithiasis in children and exposure to melamine: A review of the epidemiological literature

“…For example, Chang et al conducted a 5-year follow-up of 207 pediatric urolithiasis patients. 46 At 5 years of follow-up, residual stones were observed in 17/198 ¼ 8.6% of the patients; stones already present 5 years ago but not washed out. This persistence figure of 8.6% is quite low as compared to persistence rates of 40% reported for children with urolithiasis unrelated to ME exposure.…”

“…Following these cross-sectional screening type of studies, clinicians set up follow-up studies on urolithiasis cases to assess the longer-term health impacts. Many of these follow-up studies have been conducted, for example, Shen et al, 41 Shang et al, 42 Dai et al, 43 Zou et al, 44 He et al, 45 and Chang et al 46 A systematic review by Wang et al covering 26 studies on the clinical profile and prognosis of ME-induced urolithiasis concluded that there were inconsistencies regarding the clinical features and prognosis of the reported cases. 47 Overall, however, patients had small calculi and could recover without surgical intervention.…”

Self-Assembled Complex of Melamine and Alloxan

“…Supramolecular chemistry has been receiving a great deal of attention due to the synthesis of structures with well-defined architectures via non-covalent interactions between individual components [1][2][3][4][5][6]. Hydrogen bonding along with self-assembling is responsible for the formation of important architectures like DNA and protein folding.…”
