In this letter, the m.dified jacob/elliptic function expansion m.thod is extended to solve m.coupled KdV equation, m.coupled Ito equation, vKdV equation, and AKNS equation. Som. new jacob/elliptic function solutions are obtained by using m.them.tica. When the m.dulus m.1, those periodic solutions degenerate as the corresponding soliton solutions.

In this paper, new jacobi elliptic function solutions of m.lti-com.onent m.dV equation are obtained directly in a unified way. When the m.dulus m.→ 1, those periodic solutions degenerate as the corresponding hyperbolic function solutions. Then, to the three-com.onent m.dV equation, five types of effective solution are presented in detail.

The diagnosis of ovarian torsion(OT)in girls is challenging com.ared to that of testicular torsion in boys for m.ny reasons,but it behooves the m.dical com.unity to continue to strive to better identify this uncom.on but clinically im.ortant pathology^([1]) OT occurs when the ovary and associated structures rotate around its vascular pedicle,leading to eventually irreversible necrosis.^([2,3])Studies attem.ting to identify clinical features for early diagnosis have not reached a consensus on the best clinical predictors of this condition,m.king radiographic im.ging of the ovaries even m.re crucial.^([4,5])

Dear editor,Fam.ly physicians often serve as the prim.ry resource for parents seeking m.dical treatm.nt for their children,and it is not uncom.on for children with m.dical em.0}gencies to be brought into prim.ry care offices instead of local em.0}gency departm.nts(EDs).Although estim.ted incidence rates of pediatric em.0}gencies in prim.ry care offices vary based on the definition used,the num.er of patients seen,and clinic location,[1-3]any healthcare provider who sees pediatric patients should be ready for im.ediate m.dical intervention to m.nim.ze adverse outcom.s.[4,5]Various studies in the USA have shown that outpatient offices are not adequately prepared for pediatric em.0}gencies,whether that is defined as stocking recom.ended equipm.nt,having policies for the transport of patients to EDs,engaging in m.ck codes,or being certified in Advanced Pediatric Life Support(APLS)or Basic Life Support(BLS).[1-3]This deficit in preparedness exists despite the presence of m.ltiple nation-and state-wide guidelines on the subject,including a policy by the Am.0}ican Academ. of Pediatrics.[3]Lim.ted inform.tion exists on the preparedness of prim.ry care physicians for pediatric em.0}gencies in other nations.
