Hemangiomas are relatively common in the head and neck region, but their occurrence in the temporal bone are extremely rare. The hemangioma of the external auditory canal (EAC) is a rare otologic entity as only 22 cases of hemangioma of the EAC have been reported worldwide. Here we report a patient presenting with pulsatile tinnitus, which turned out to be caused by capillary hemangioma arising from the posterior medial portion of external auditory canal touching the tympanic membrane. Surgical excision of the tumor was successful. The clinical manifestations and management of benign vascular lesions of the EAC are discussed with a review of literature.

Objective: The study aimed to investigate whether mindfulness could mitigate the impact of job and interpersonal demands arising from stressful organizational cultures in predicting depression during the COVID-19 pandemic. Methods: A total of 280 Korean physical therapists participated in this study. To verify the mediated moderation model, this study implemented an SPSS 26.0 PROCESS Macro (v.3.5) that was based on the verification of Hayes' conditional indirect effect. Results: The study confirmed the moderated mediation effect of mindfulness on the mediating relationship between stressful organizational culture, job demands/interpersonal demands, and depression. Moreover, the conditional indirect effect of mindfulness was found to be statistically significant. However, the impact on interpersonal stress differed from anticipated outcomes. Conclusions Mindfulness, applicable within the framework of the Job Demands-Resources model theory, served as a resource variable and moderated the impact of organizational culture on members' depression. Amidst ongoing debates on mindfulness effectiveness, this study partially confirmed its potential within the Job Demands-Resources model, suggesting a role in mitigating the influence of organizational culture on members' depression as a resource variable.

PURPOSE: Postpartum hemorrhage (PPH) is a major cause of maternal death. The aim of this study is to analyze the effect of clinical pathway (CP) and off-hours effects in PPH patients who visit the emergency department. METHODS: A retrospective study of PPH patients who visited the emergency department between December 1, 2005 and February 28, 2014 was conducted. A multidisciplinary team was designed for PPH in August 1, 2009. We compared time to intervention, volume of transfusion, length of stay (LOS), and uterus preservation rate between the before CP group and after CP group. RESULTS: A total of 143 post CP groups were compared with 101 before CP visits. Time to operation was less compared with the pre CP group (77 min (22-140) vs 47.5 min (13-114) p=0.011). Volume of transfusion and admission to intensive care units (ICU) were increased in the post CP group. (2 (0-16) vs 2 (0-25) p=0.045, 20 (19.8%) vs 54 (37.8%) p=0.003) LOS of ICU was lower than in the pre CP group and uterus preservation was higher than in the pre CP group. (0 day (0-43) vs 0 day (0-6) p=0.015, 82 (81.2%) vs 129 (90.2%) p=0.042) Time to angiographic embolization was less in the post-CP group with on-duty visits than in post-CP with off hours visits. (38.50 min (16-112) vs 71.0 min (28-633), p=0.025) CONCLUSION: A clinical pathway for PPH is associated with improvement of uterine preservation rate and reduced LOS of ICU. However this CP could not eliminate off-hour effects from time to intervention.

Solitary pulmonary lymphangiomas are extremely rare. We report here on an unique case of solitary pulmonary lymphangioma in an adult. A well-circumscribed, 6 cm-sized, pleural based lesion with fluid attenuation was found in a 50-year-old Korean male. He had no previous history of disease or trauma. The wedge-resected lung revealed an ill-demarcated lesion with multiple microscopic cysts and the cystic walls had loose intervening stroma.

Giant cell fibroblastoma (GCF) is a rare soft-tissue sarcoma of fibroblastic origin. To the best of our knowledge, only one brief description of the MRI findings of GCF exists in the pathologic literature. Herein, we report a case of histologically proven GCF in a 3-year-old boy who underwent ultrasonography and MRI of a superficial mass in the abdominal wall.

Few studies have reported on the clinical utility of targeted next-generation sequencing (NGS) for breast cancer in Korea. We retrospectively reviewed the targeted NGS data of 219 patients with breast cancer who underwent surgical resection between August 2018 and April 2021.Here, we described the mutational profiles of breast cancer and examined their prognostic implications. The most frequently mutated gene was PIK3CA (n = 97/219, 44.3%), followed by TP53 (n = 79/219, 36.1%), AKT1 (n = 23/219, 10.5%), and GATA3 (n = 20/219, 9.1%). TP53 mutations were associated with aggressive histologic features. We followed up for 31 (range, 1–39) months and observed 11 (5.0%) recurrences: nine were TP53 mutant and two were TP53 wild-type. Multivariable analysis revealed that TP53 mutation was an independent prognostic factor for recurrence (p = 0.012). Although no drug is currently available for TP53 mutations, it is valuable to know the mutational status of TP53 for the precise management of breast cancer.
