Coloboma can affect the adnexa and/or the eyeball. We report the iconography of two cases of ocular colobomas and one case of eyelids coloboma at the IOTA CHU. Case 1: This was a 32-year-old patient who consulted for decreased visual acuity in the left eye. The clinical examination found visual acuity of 10/10 in the right eye and hand movement in the left eye. Biomicroscopic examination revealed an iris and chorioretinal coloboma encompassing the papilla. Case 2: This was a 3-year-old child. Who consulted for eyelid malformation since birth. On ophthalmological examination, there was a bilateral coloboma of the inner half of the upper eyelid, associated with an underlying symblepharon and left eye corneal dystrophy. Our course of action consisted of a release of the symblepharon followed by a blepharoplasty which allowed a good anatomical and functional restitution. Case 3: This was a 15-year-old patient who consulted for bilateral visual acuity loss measured by counting fingers at 1m in the right eye and counting fingers at 3m in the left eye. The biomicroscopic examination found a bilateral papillary coloboma associated with a bilateral progressive cataract, an old detachment of the left retina. The etiological assessment was unremarkable. Conclusion: Coloboma is a congenital condition that can affect all parts of the eye. We reported three cases of colobomas, one palpebral, one iris and chorioretinal, and finally, one papillary associated with other ocular pathologies.展开更多

文摘Amyotrophic lateral sclerosis is a rare neurodegenerative disease characterized by the involvement of both upper and lower motor neurons.Early bilateral limb involvement significantly affects patients'daily lives and may lead them to be confined to bed.However,the effect of upper and lower motor neuron impairment and other risk factors on bilateral limb involvement is unclear.To address this issue,we retrospectively collected data from 586 amyotrophic lateral sclerosis patients with limb onset diagnosed at Peking University Third Hospital between January 2020 and May 2022.A univariate analysis revealed no significant differences in the time intervals of spread in different directions between individuals with upper motor neuron-dominant amyotrophic lateral sclerosis and those with classic amyotrophic lateral sclerosis.We used causal directed acyclic graphs for risk factor determination and Cox proportional hazards models to investigate the association between the duration of bilateral limb involvement and clinical baseline characteristics in amyotrophic lateral sclerosis patients.Multiple factor analyses revealed that higher upper motor neuron scores(hazard ratio[HR]=1.05,95%confidence interval[CI]=1.01–1.09,P=0.018),onset in the left limb(HR=0.72,95%CI=0.58–0.89,P=0.002),and a horizontal pattern of progression(HR=0.46,95%CI=0.37–0.58,P<0.001)were risk factors for a shorter interval until bilateral limb involvement.The results demonstrated that a greater degree of upper motor neuron involvement might cause contralateral limb involvement to progress more quickly in limb-onset amyotrophic lateral sclerosis patients.These findings may improve the management of amyotrophic lateral sclerosis patients with limb onset and the prediction of patient prognosis.

文摘China and 10 ASEAN countries have fully completed negotiations on the Version 3.0 China-ASEAN Free Trade Area(CAFTA),a milestone in bilateral trade cooperation that will inject greater momentum and stability into the world economy.The achievement was announced during a special online meeting of economic and trade ministers from China and ASEAN on May 20,according to China’s Ministry of Commerce.CAFTA 3.0 will send a strong signal in support of free trade and open cooperation,said the ministry,noting that the agreement will inject greater certainty into regional and global trade and serve as a model for openness,inclusiveness and win-win cooperation.

文摘Background:Deficits in quadriceps strength of the injured leg have been observed in patients following anterior cruciate ligament(ACL)reconstructions and may contribute to ACL re-injury risk.Single-leg forward hopping is a widely used task for assessing knee function in patients following ACL reconstructions as it has been shown not to be particularly challenging to the knee.This study aimed to quantify the effect of decreased quadriceps strength induced by a fatigue protocol on hopping performance and lower limb mechanics in single-leg forward,vertical,and backward hopping.Methods:Thirty-four injury-free participants performed single-leg forward,vertical,and backward hopping on both legs pre-and post-fatigue,with 1 leg experiencing a fatigue protocol.Peak moments,power,and work of hip,knee,and ankle joints were quantified during the jumping phase.Hopping performance and bilateral asymmetries in performance were assessed.Results:Single-leg backward hopping demonstrated the greatest knee moments,power,and work compared to forward and vertical hopping,regardless of leg and fatigue.Fatigue protocol resulted in significantly less knee moments,power,and work,and decreased performance of the fatigued leg among all tasks.Bilateral symmetries in hopping performance decreased in post-fatigue,with the greatest decrease in backward hopping.Conclusion:The greater sensitivity of the backward hopping to detect quadriceps fatigue suggests it may act as a better or at least an additional metric to evaluate quadriceps strength deficits.The findings may contribute to the development of a clinically applicable and valid strength assessment to monitor the rehabilitation progress in patients following ACL reconstructions.
文摘BACKGROUND Congenital hallux varus(CHV)is a rare form of hallux varus deformity,characterized by medial deviation of the first toe at the metatarsophalangeal joint.It may be primary or secondary and presents clinically with pain and asymmetry with footwear.CASE SUMMARY We documented a case of a 6-year-old girl with bilateral CHV,accompanied by adduction of the toes in the left foot.Clinical diagnosis was made by physical examination and X-ray imaging based on Bleck’s classification.Conservative treatment did not show any noticeable improvement,so the child underwent corrective surgeries on both feet.CONCLUSION The patient’s family history is positive,which requires us to take into account the importance of checking for a family history with any complaint of CHV,and both feet must be evaluated to confirm whether the deformity is unilateral or bilateral.
文摘In what is a great news for those engage in the co!ee sector,the government of Burundi and the Chinese embassy in Bujumbura recently announced the commencement of exports of Burundian co!ee to China.The first consignment of 38 tonnes of green co!ee has already been shipped to China.This will further strengthen the economic and trade relations between the two countries.China Henan International Cooperation Group(CHICO)will be responsible for selling Burundian co!ee in China.
文摘MADRID and Beijing,though thousands of miles apart,have become a model for mutual learning between different civilizations through mutual respect and dialogue.In November,Spanish King Felipe VI will visit China.This will be another milestone in bilateral relations following the 2007 visit of former Spanish King Juan Carlos I to China and President Xi Jinping’s visit to Spain in 2018.
