Surgical management of Dandy-Walker syndrome in infants and the literature review / 中国综合临床

Dandy-Walker syndrome is one of the posterior fossa malformations, which is easily confused with arachnoid cyst or cerebellar dysplasia in clinical practice, leading to misdiagnosis. Dandy-Walker syndrome is easy to be combined with hydrocephalus, resulting in increased intracranial pressure, increased head circumference, growth retardation, spastic hemiplegia and other manifestations, and can also be accompanied by other nervous system malformations. On February 27, 2021, a child with Dandy-Walker syndrome with growth retardation as the primary manifestation was admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine. After multiple surgical treatment, the child's hydrocephalus was significantly improved. Through the analysis of the clinical data of the child's operation and the treatment of complications, it is helpful to improve the clinicians' understanding of the surgical treatment of the disease.

Analysis of medical disqualification of 1281 students recruited into Air Force youth aviation school / 军事医学

Objective To analyze the results of the final aviation medical examination of 1281 students recruited into Air Force youth aviation schools in Hunan and Hubei provinces in order to provide reference for establishing the items and standards of medical selection .Methods The data of 1281 students who participated in final aviation medical examination of Air Force youth aviation schools in 2016 were collected , who came from 28 cities in the above two provinces .The disqualification rate and related unqualified medical items were calculated , and the differences of the disqualification rate and medical geographical areas in the 28 cities were analyzed .Results According to the disqualification rate , the top five departments were ophthalmology , otolaryngology, surgery, radiology and ultrasonic departments .The top 10 unqualified items were the lack of distant vision , fundus diseases , nasal anomaly , ametropia and strabismus , spine abnormality , audition abnormality, vestibular function badness , vitreous opacity, and lens abnormalities.There was no significant difference between the 28 cities in the disqualification rate (P >0.05) or between the two provinces (P >0.05). Conclusion The results of the final aviation medical examination reflect the quality and efficiency of the initial aviation medical examination .To improve the quality of medical selection , further research is needed to set a scientific standard for the initial aviation medical examination while strengthening the scientific protection and intervention of distant vision .The efficiency of selection depends on improving the accuracy of initial aviation medical examination in nasal cavity structure, body shape ,and lens opacity .With a better understanding of the disqualification rate and abnormal items in different cities , a scientific arrangement of professional staff and technical force can make the initial aviation medical examination better, thus effectively reducing the rate of false elimination rate and misdiagnosis .
