PURPOSE: The purpose of this study was to test the effectiveness of a post-traumatic stress disorder management program in reducing firefighters' post-traumatic stress and depression. METHODS: This study employed a nonequivalent control group design using pretest and posttest measurements. Sampling was conducted with a convenient method. 44 firefighters (experimental group=22, control group=22) who were at high risk of post-traumatic stress disorder (PTSD) and depression were selected from 1,337 firefighters working in fire stations in multiple sites. Data were collected between August and October 2016. The post-traumatic stress disorder management program was provided to the experimental group for 8 weeks. Data were analyzed using descriptive statistics and chi-squared and independent t-tests. RESULTS: Compared with the control group, participants in the experimental group showed significantly decreased scores for PTSD (t=−3.34, p=.002) and depression (t=−2.09, p=.043). CONCLUSION: Our study findings show that firefighters' PTSD and depression can be systematically managed. Clinical practice should strengthen the ability to cope with PTSD by relieving the psychological trauma of firefighters who experience repeated traumatic events.

Kidney cortex necrosis is a relatively rare cause of acute kidney injury and is characterized by complete or partial destruction of the renal cortex, but sparing of the medulla. Tranexamic acid has antifibrinolytic activity and is used to reduce bleeding. We report a rare case of kidney cortex necrosis caused by tranexamic acid. A 49-year-old woman complained of coughing up blood-tinged sputum. She had a history of bronchiectasis and was treated with tranexamic acid for 3 days. Four days after admission, she developed anuria and azotemia. Computerized tomography showed enhancement of the renal medulla, but not the bilateral renal cortex. The patient was treated with hemodialysis, and has since been maintained on hemodialysis for 6 months. Due to the development of kidney cortex necrosis in patients treated with tranexamic acid, all its potential complications should be considered.

Malnutrition and inflammation are related to high rates of morbidity and mortality in hemodialysis patients. Resistin is associated with nutrition and inflammation. We attempted to determine whether resistin levels may predict clinical outcomes in hemodialysis patients. We conducted a prospective evaluation of 100 outpatients on hemodialysis in a single dialysis center (male, 46%; mean age, 53.7 +/- 16.4 yr). We stratified the patients into 4 groups according to quartiles of serum resistin levels. During the 18-month observational period, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival (log rank test, P = 0.016). After adjustment of all co-variables, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival, compared with reference resistin levels. Higher levels of interleukin-6 were an independent predictor of poor hospitalization-free survival. In contrast, serum resistin levels were not correlated with interleukin-6 levels. The current data showed that low resistin levels may independently predict poor hospitalization free survival in hemodialysis patients.

Purpose: We aimed to identify the genetic causes of hypospadias in children using targeted gene panel sequencing for disorders of sex development (DSD). Materials and Methods: This study included 18 twin boys with hypospadias: seven and two pairs were monozygotic and dizygotic twins, respectively, and six were discordant and three were concordant twins. Targeted gene panel sequencing for 67 known DSD genes was performed. Sequence variants were classified into five different categories, pathogenic, likely pathogenic, variants of uncertain significance, likely benign, and benign, following the American College of Medical Genetics and Genomics Standards and Guidelines. Results: The mean gestational age and birth weight were 35.3±2.0 weeks and 1.96±0.61 kg, respectively, with seven patients being small for gestational age. Hypospadias was present in 12 patients, with posterior type in 33.3% and anterior type in 66.7%.In three families with twins, both siblings had hypospadias. In addition, cryptorchidism was observed in one subject. Surgical correction of hypospadias was performed at a mean age of 22.1 months. Molecular analysis identified 12 different genetic variants, including two pathogenic mutations in the AMH (p.E389*) and SRD5A2 (p.R246Q) genes, found in subjects with hypospadias, respectively. However, only heterozygous mutations were detected. Conclusions This study did not identify a definitive genetic component contributing to the development of hypospadias; however, the findings suggest that intrauterine growth retardation may play a significant role.
