Application of island flap and its combined flap on repairing nasal alae defects / 中华耳鼻咽喉头颈外科杂志

Objective: To evaluate the application of island flap and combined flap in one-stage reconstruction of nasal alae defects after external nasal tumor resection. Methods: Data of 11 patients with perforating or full-thickness defects of the alae after nasal tumor resection in XuanWu Hospital, Capital Medical University between June 2016 and February 2021 were analyzed retrospectively. There were 7 males and 4 females, and the ages ranged from 51 to 89 years. Island flap, island flap combined with nasolabial flap or V-Y advancement flap, and island flap combined with bilobed flap were applied according to the range of defects. Descriptive statistical method was applied to analyze the treatment effects. Results: All flaps of the 11 patients were successful survival and the incisions were primary healing. Being followed up for 5 to 59 months, the patients had satisfying appearance and ventilation function, and no tumor relapsed. Conclusion: For the patients with nasal alae defects after external nose tumor resection, selecting suitable island skin flap or combined skin flap can be used to reconstruct the ideal nasal appearance and function of the nose.

Advances in mechanism, diagnosis and treatment of IgG4-related ophthalmopathy / 国际眼科杂志(Guoji Yanke Zazhi)

@#IgG4-RD is a newly recognized chronic and systemic disease. IgG4-positive plasma cells play a part in the occurrence and development of this disease. “IgG4-related ophthalmic disease(ROD)” was proposed for the involvement of eyes in general. The clinical manifestations of IgG4-ROD are various due to different involved parts and have unique pathologic features compared with other organs. With a better understanding on this disease in recent years, diagnosis and treatment rate has been improved. In this paper, we will discuss the definition, epidemiology, pathogenesis, clinicopathological features, diagnosis and differential diagnosis, serum biochemical indices, imaging examinations and treatment about IgG4-ROD.

Analysis of allergen variation for 3292 patients with allergic rhinitis / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the variation of common allergens in patients with allergic rhinitis in recent 4 years in Tianjin First Center Hospital.</p><p><b>METHODS</b>The medical records of skin prick test on 3292 patients with allergic rhinitis between 2009 and 2012 were restrospectively analyzed. The changing trend of various allergens in 4 years and distribution differences were compared. The differences of the top 5 allergens in under age group, adult group and different gender group were further analyzed by SPSS 19.0 software.</p><p><b>RESULTS</b>The positive rate of dermatophagoides farinae was increasing year by year, from 45.1% in 2009 to 66.3% in 2012, and the positive rate of dermatophagoides pteronyssinus increased from 42.0% in 2009 to 58.6% in 2012, the difference was statistically significant (χ(2) value was 68.70, 41.55, all P < 0.01). The positive rate of dermatophagoides farinae and dermatophagoides pteronyssinus in adult group and male group showed significant upward trend year by year (χ(2) value was 75.85, 69.93, 274.25, 42.62, all P < 0.01), but not in adult group and female group. The positive rate of quinoa, mugwort and humulus scandens decreased year by year between 2009 and 2011(χ(2) value was 22.08, 11.64, 203.19, all P < 0.01), but increased again in 2012(χ(2) value was 21.55, 29.38, 12.40, all P < 0.01).</p><p><b>CONCLUSIONS</b>There is a tendency of change of allergens in patients with AR. This phenominon may be helpful for doctors to choose the type of skin prick liquid.</p>
