Background:
This study aimed to identify chronicity predictors of pediatric primary immune thrombocytopenia (ITP).
Methods:
This study retrospectively reviewed the medical records of patients with primary pediatric ITP admitted to a tertiary medical center between 2010 and 2021.Forty-five patients with a platelet count <20,000/L at the time of diagnosis who were treated with intravenous immunoglobulin (IVIG) were enrolled in this study.
Results:
According to the disease phase, 28, 6, and 11 patients were classified into the newly diagnosed (ND), persistent, and chronic groups, respectively. The number of patients over 6 years of age was significantly higher in the chronic group than in the ND and persistent groups. After 14 days of IVIG treatment, more patients had a complete response in the non-chronic groups than in the chronic group. In univariate analysis of risk factor for chronic ITP, age 6 years or older and IVIG dose <2 g/kg were found to be risk factors for chronic ITP, and these two factors were also confirmed as significant risk factors in multivariate analysis.
Conclusion
In conclusion, in our study, patients over 6 years of age, and those who received IVIG doses less than 2 g/kg were more likely to progress to chronic ITP.

Background:
Lip lifting is a widely accepted and efficient surgical procedure for volumizing the upper lip to achieve a more youthful appearance. A previous study by Hwang et al. identified the lip-related ratios most preferred by Koreans: a lip height-to-width ratio (LTW) of 0.4, an upper-to-lower vermilion ratio (ULR) of 0.8, and an upper vermilion thickness-to-upper lip height ratio (VUL) of 0.5. The current study investigated whether the attractive lip ratio favored by Koreans could be obtained with central upper lip lift surgery.
Methods:
This retrospective chart review included South Korean patients who underwent central lip lifts between 2015 and 2019 at a single center. The LTW, ULR, VUL, and columellar-labial angle were measured using the patients’ preoperative and postoperative clinical photographs.
Results:
A total of 87 patients underwent central lip lifts. Before surgery, the mean LTW was 0.34, the mean ULR was 0.76, and the mean VUL was 0.30. After surgery, the LTW increased to an average of 0.39, the ULR increased to 0.84, and the VUL increased to 0.393. The patients’ postoperative ratio values were close to the attractive lip ratio values proposed by Hwang et al. The average columellar-labial angle decreased from 101.59° to 95.04°, and therefore did not interfere with the aesthetic relationship between the nose and lips.
Conclusions
The central lip lift was an efficient cosmetic technique that provided the Korean ideal shape for attractive lips.
