Bone destruction of orbital wall in idiopathic orbital inflammatory pseudotumor: does it always imply malignancy?

Aim: To assess the clinical presentations and outcomes of idiopathic orbital inflammatory pseudotumor (IOIP) patients with orbital wall bone destruction (OWBD) and to propose an expanded classification system that includes bone destruction.

Methods: The study retrospectively reviewed clinical presentations, imaging findings, treatment modalities, and outcomes of six patients diagnosed histopathologically with IOIP and OWBD at the Beijing Tongren Hospital, Capital Medical University between October 2018 and June 2021.

Results: Over two years, 6 (10%) of 60 IOIP patients at our hospital exhibited OWBD, but this may overrepresent severe cases.

Treatment of lacrimal gland adenoid cystic carcinoma: a systematic review and Meta-analysis.

Aim: To evaluate lacrimal gland adenoid cystic carcinoma (LGACC) of prognosis in patients who underwent different treatment regimens.

Methods: We searched PubMed, EMBASE, and the Cochrane Library for studies done on the treatment of LGACC, between January 1987 and April 2022. A Meta-analysis was conducted to pool the 5-year overall survival rate (OR), and the 5-year recurrence rate (RR) and 5-year metastasis rate (MR) were assessed.

[Technology of advanced glycation endproducts fluorescence measurement and precorrection].

The necessity to measure advanced glycation endproducts (AGE) was analyzed in the present paper, and the apparatus for measuring skin autofluorescence was also designed making use of the special excitation spectrum and emission spectrum. A portion of tissue at the volar side of the arm of individuals (11 diabetes and 19 control subjects) was illuminated with excitation light, i.e.

[Design of advanced glycation endproducts fluorescence spectrum detecting system].

The method of making use of the technique of fluorescence spectrum to detect advanced glycation endproducts is discussed in the present pape. The emphasis is on the principle and structure of the fluorescence spectrum detecting system. In the end, the authors made use of the system to detect the excitation spectrum at the wavelengths of 365nm, 370nm, 375nm, 380nm and 385nm, respectively, and the authors found that 375nm is the best excitation wavelength.
