To analyze the association between climate changes in the macroregions in the state of São Paulo and testicular torsion treated cases.
The cases were selected in the Brazilian Public Health Data System Database from January 2008 to November 2016. All surgical procedure records were identified by the Hospital Admission Authorization document. Two codes were selected to process the search: testicular torsion (surgical cure code) and acute scrotum (exploratory scrototomy code). The macroregions were grouped in five areas linked to climate characteristics by International Köppen Climate Classification.
A total of 2,351 cases of testicular torsion were registered in the period. For the areas B, C and E (testicular torsion n=2,130) there were statistical differences found in association of testicular torsion cases and decreased temperature (p=0.019, p=0.001 and p=0.006, respectively), however, in analyses for the areas A and D statistical differences were not observed (p=0.066 and p=0.494).
Decrease in temperature was associated with testicular torsion in three macroregions of São Paulo. The findings support the theory of cold weather like a trigger in occurrence of testicular torsion in a tropical climate region.
分析巴西圣保罗州各地区气候变化与睾丸扭转治疗病例之间的关系。
本研究从 2008 年 1 月至 2016 年 11 月，在巴西公共卫生数据系统数据库中选取了病例。所有手术记录均通过住院授权文件识别。选择了两个代码来进行搜索：睾丸扭转（手术治愈代码）和急性阴囊（阴囊探查术代码）。根据国际科彭气候分类法，将这些大区分为五个与气候特征相关的区域。
在此期间，共登记了 2351 例睾丸扭转病例。对于 B、C 和 E 区（睾丸扭转 n=2130），睾丸扭转病例与温度降低之间存在统计学差异（p=0.019、p=0.001 和 p=0.006），但在 A 和 D 区的分析中未观察到统计学差异（p=0.066 和 p=0.494）。
在圣保罗的三个大区，温度下降与睾丸扭转有关。这些发现支持了在热带气候地区，寒冷天气可能是睾丸扭转发生的诱因这一理论。
