Quantitative tissue velocity imaging evaluation of ventricular function in obstructive sleep apnoea-hypopnoea syndrome in children.

This study aimed to evaluate the changes in left and right ventricular functions of children with obstructive sleep apnoea-hypopnoea syndrome (OSAHS) and to determine the efficacy of surgical treatment for OSAHS in children. The subjects included 20 normal controls and 55 children of OSAHS with adenoid and/or tonsil hypertrophy diagnosed by polysomnography (PSG). We divided the children with OSAHS into the mild group, moderate group and severe group of OSAHS according to the condition of apnoea-hypopnoea index (AHI) and the lowest of oxygen saturation (LSaO₂).

Increased osteopontin expression is associated with progression from vulvar precancerous lesions to vulvar squamous cell carcinoma.

Purpose: Vulvar squamous cell carcinoma (VSCC) contributes to about 3-5% of all gynecological cancers. Vulvar intraepithelial neoplasia (VIN) and vulvar lichen sclerosus (VLS) are regarded as precancerous lesions. Early detection and treatment of precancerous lesions may prevent development of VSCC.

[Efficacy of high-resolution CT in differential diagnosis of chronic suppurative otitis media and cholesteatoma otitis media by soft-tissue shadows].

Objective: To evalute the efficacy of high-resolution CT(HRCT) in differential diagnosis and treatment of chronic suppurative otitis media and cholesteatoma otitis media by soft-tissue shadows.

Methods: HRCT scanning was performed in 120 cases, 153 ears, with chronic otitis suppurative media and cholesteatoma otitis media, of which original data were processed with multi-planar reconstruction (MPR) and maximum intensity projection (MIP), the characteristics of the soft-tissue shadows' growth, window width or window leveling and bony destruction were respectively observed, as well as compared with the surgery findings.

Results: In 120 patients (153 ears), 109 ears were diagnosed as cholesteatoma otitis media, and 44 ears were diagnosed as chronic suppurative otitis media, among which 33 ears had granulation tissue and 11 ears had secretion.
