Tinnitus Related to Forceful Eyelid Closure: A Case Report.

Tinnitus is a common complaint in the clinical setting and can be classified into sensorineural and objective tinnitus. The sources of objective tinnitus may either come from para-auditory structures, such as myogenic or vascular structures, or the middle ear muscles. One type of objective tinnitus of muscular origin is known as forceful eyelid closure syndrome (FECS).

Hybrid model of a cement rotary kiln using an improved attention-based recurrent neural network.

A rotary kiln is core equipment in cement calcination. Significant time delay, time-varying, and nonlinear characteristics cause challenges in the advance process control and operational optimization of the rotary kiln. However, the traditional mechanism model with many assumptions cannot accurately represent the dynamic kiln process because kinetic parameters are difficult to obtain.

[Characteristics of nystagmus and its therapeutic effect in the reduction of posterior semicircular canal benign paroxysmal positional vertigo].

By observing the nystagmus forms at different positions during Epley reduction in patients with posterior semicircular canal benign parochial positional vertigo（PC-BPPV）, to compare the effects of the first reduction, and to further summarize the possible causes of reduction failure and the prognosis of patients with different nystagmus forms. A retrospective analysis of 191 PC-BPPV patients diagnosed with PC-BPPV showed that 95 cases had positive nystagmus during the reduction process（group A）, 69 cases had no nystagmus （group B）, and 27 cases had reverse nystagmus （group C）. All the patients were diagnosed by G-Force BPPV and were treated through simulative Epley CRP.

[Analysis of reduction effect of the evoked nystagmus in the non-affect side during Dix-Hallpike or Roll-test in unilateral posterior semicircular canal benign paroxysmal positional vertigo].

Comparative analysis of the reduction effect of the evoked nystagmus in the non-affect side during Dix-Hallpike（D-H） or Roll-test in unilateral posterior semicircular canal benign paroxysmal positional vertigo（PC-BPPV） and PC-BPPV without above evoked nystagmus. Retrospective analysis of 210 patients diagnosed with unilateral PC-BPPV by G-Force BPPV CRP system was made. Among them, 18 patients exhibited positive nystagmus only when the non-affected side was stimulated by D-H test（Group A）, 30 was evoked only when stimulated by Roll-test（Group B）, 26 was evoked when stimulated by both Roll-test and the non-affected side D-H test（Group C）, 136 without nystagmus in the above positions（Group D）.

Bone loss in chronic kidney disease: Quantity or quality?

Chronic kidney disease (CKD) patients experience bone loss and fracture because of a specific CKD-related systemic disorder known as CKD-mineral bone disorder (CKD-MBD). The bone turnover, mineralization, and volume (TMV) system describes the morphological bone lesions in renal osteodystrophy related to CKD-MBD. Bone turnover and bone volume are defined as high, normal, or low, and bone mineralization is classified as normal or abnormal.
