Brachial plexitis is characterized by acute onset pain followed by weakness due to dysfunction of the nerves comprising the brachial plexus. The exact pathophysiology of this condition remains unknown, but certain associations have been described in the literature. It is thought to follow recent infections, especially viral illnesses in 25-55% of the patient population. ⋯ The acute denervation of certain nerves in the brachial plexus is suspected to be due to reconstitution of his immune system. In the literature, there have been no reports of such. Reporting this in this patient would lead to further recognition of this rare, but plausible etiology for this condition.

Interbody spacers have been successfully used in spinal fusion procedures with the aim to restore disc height, provide stability and promote the bone fusion. The authors aimed to evaluate the efficacy of structural body allograft versus polyetheretherketone (PEEK) implants in patients undergoing spinal fusion surgery. ⋯ Our results corroborate that structural allografts are highly effective in promoting bony fusion compared to PEEK implants in patients undergoing spinal fusion surgery.

There is currently no consensus regarding surgical indications for symptomatic sacral perineural cysts. ⋯ To the best of our knowledge, this is the first study to have performed a quantitative analysis of the dynamics of CSF in sacral perineural cysts using myelographic CT. Sixty-seven percent of patients benefited from surgery; however, our criteria may not be a necessary and sufficient condition for patient selection because 33% did not respond to surgery despite the successful elimination of the check-valve.

To explore patient demographics as to predicting vestibular schwannoma (VS) size and treatment plan within a single institution. ⋯ Older age is associated with smaller tumors, while married patients have larger tumors at diagnosis as compared to non-married patients. Furthermore, married patients are more likely to pursue treatment, specifically surgery, as compared with non-married patients, while patients who live farther from the center are more likely to pursue treatment.

The paper uses ultrasound imaging standard section to examine the fatal central nervous system in early pregnancy, combined with ultrasound imaging in the diagnosis of fatal central nervous system malformation in the middle and late pregnancy, to determine the feasibility of ultrasound imaging in the detection of central nervous system abnormalities in the first trimester of the foetus. The paper selected 2,701 pregnant women from the Department of Ultrasound in our hospital from November 2012 to November 2016 to screen for the transparent layer of the fatal neck in early pregnancy, with a total of 2751 cases. The paper uses Madison V20 and Madison XG colour Doppler ultrasound diagnostic instrument, the probe frequency is measured from 2.0MHz to 3.5MHz, grouped according to gestational age, the statistical section of the case is displayed, and the NT value is used to count the ultrasound image during early pregnancy. ⋯ At the same time, the number of positive cases and CNS malformations in this group were few. The positive cases detected in early pregnancy were severe malformations of CNS. The diagnosis of other CNS malformations in the foetus needs further study.
