Breast magnetic resonance imaging (MRI) is the most sensitive method available for detecting breast cancer, and its use in clinical practice is on the rise. Preoperative breast MRI plays a vital role in assessing the full extent of disease and identifying additional lesions in the contralateral breast that conventional imaging may overlook. These unexpected findings can lead to significant changes in treatment approaches and may ultimately affect long-term outcomes for patients. Despite this, the value of preoperative breast MRI for early-stage breast cancer patients remains a contentious issue. This review evaluates the existing literature on the influence of preoperative breast MRI on clinical outcomes in this patient population.

Fournier gangrene (FG) is a rare life-threatening infection j that can occasionally extend beyond the perineum into the retroperitoneal space. Preperitoneal involvement in female patients is extremely rare. We report a unique case of a 59-year-old female with FG, characterized by atypical preperitoneal extension. Despite initial treatment failure, the patient recovered following emergency debridement, and targeted antibiotic therapy. This case underscores the importance of early diagnosis, timely surgical intervention, and multidisciplinary care in managing atypical FG presentations in female patients. It emphasizes the need for prompt and aggressive management to improve survival in these rare instances.
3.Laparoscopic Emergency Surgery for Perforated Peptic Ulcer: A Narrative Review
Journal of Acute Care Surgery 2025;15(1):1-4
Perforated peptic ulcer (PPU) is developed in 2%-10 % of peptic ulcer. The essential treatment is emergent surgical repair. Usually, the surgical repair with or without an omental patch is performed by laparotomy. The laparoscopic emergency surgery (LES) for PPU is increasingly being preferred with the innovation of laparoscopic devices and procedures and increase of surgeon’s expertise and experiences.Generally, a laparoscopic approach is recommended in stable patient. And, in selected patient with instability, a laparoscopic approach may be adopted. The patient selection criteria is recommended in hemodynamic stability, surgeon’s skills, cardiovascular or pulmonary comorbidity and Boey score.These LES rate differences for PPU are resulted that the variability in the healthcare infrastructure and patient-related factors between countries. The surgeon’s decision about LES for PPU is affected by various factors. Even surgeon’s fatigue, physical strength, stressful feelings and poor emotional mood may be one of factors. According to published literature, the practical LES performance is affected by various limiting factors.Although guideline about laparoscopic emergency knotless suture repair for PPU is absent, the 4 retrospective studies about LES for PPU between knotless and interrupted suture repair revealed that the laparoscopic knotless suture repair using barbed suture material is alternative, feasible, safe, simple and non-inferior method. However, the recommendation evidence about single port LES for PPU is unclear.

Background and Objectives:
This study aimed to investigate the effects of hearing aids (HAs) on reducing symptoms of dizziness in patients with hearing loss (HL) and dizziness.
Subjects and Methods:
A pre- and post-intervention study was conducted between February 2022 and July 2022 at the outpatient clinic of a tertiary hospital in Seoul, South Korea. Ten participants (four males and six females) with HL and dizziness were recruited. Participants were screened using pure-tone audiometry and visual analog scale scores at baseline. Selected participants underwent the Modified Clinical Test of Sensory Interaction on Balance (mCTSIB) and Korean Dizziness Handicap Inventory (K-DHI) in the unaided state. Thereafter, participants were provided HAs and instructed to use them for at least 6 hours every day. At the 1-month follow-up, all participants were assessed in the aided state using the same tests as at baseline. All tests were performed bilaterally.
Results:
In the mCTSIB, a significant difference was observed in the foam surface-eyes closed score before (median=2.35) and after (median=2.2) HA use (p=0.049). No significant differences were observed in the K-DHI scores before and after HA use.
Conclusions
HA use may improve the static and subjective perception of balance in patients with HL and dizziness. Future research should explore the benefits of HAs under various balance conditions such as dynamic balance and gait.

Angiosarcoma associated with lymphedema is a rare soft tissue malignancy that occurs owing to chronic lymphedema, primarily following breast cancer surgery. We present a case of an 83-year-old female who developed angiosarcoma 14 years after undergoing breast cancer surgery. Diagnosis was confirmed through excisional biopsy, histopathological evaluation, and imaging. Computed tomography and magnetic resonance imaging revealed diffuse dermal thickening with an enhanced subcutaneous nodular lesion on the right arm. This unusual case emphasizes the importance of vigilant monitoring in patients with chronic lymphedema post-breast cancer surgery, as early radiologic and clinical detection can facilitate timely intervention and improve outcomes.

Purpose:
This study analyzed the pathological complete response (pCR) rates, long-term outcomes, and biological features of human epidermal growth factor receptor 2 (HER2)-zero, HER2-low, and HER2-positive breast cancer patients undergoing neoadjuvant treatment.
Methods:
This single-center study included 1,667 patients who underwent neoadjuvant chemotherapy from 2008 to 2014. Patients were categorized by HER2 status, and their clinicopathological characteristics, chemotherapy responses, and recurrence-free survival (RFS) rates were analyzed.
Results:
Patients with HER2-low tumors were more likely to be older (p = 0.081), have a lower histological grade (p < 0.001), and have hormone receptor (HorR)-positive tumors (p < 0.001). The HER2-positive group exhibited the highest pCR rate (23.3%), followed by the HER2-zero (15.5%) and HER2-low (10.9%) groups. However, the pCR rate did not differ between HER2-low and HER2-zero tumors in the HorR-positive or HorR-negative subgroups.The 5-year RFS rates increased in the following order: HER2-low, HER2-positive, and HER2-zero (80.0%, 77.5%, and 74.5%, respectively) (log-rank test p = 0.017). A significant survival difference between patients with HER2-low and HER2-zero tumors was only identified in HorR-negative tumors (5-year RFS for HER2-low, 74.5% vs. HER2-zero, 66.0%; log-rank test p-value = 0.04). Multivariate survival analysis revealed that achieving a pCR was the most significant factor associated with improved survival (hazard ratio [HR], 4.279; p < 0.001).Compared with HER2-zero, the HRs for HER2-low and HER2-positive tumors were 0.787 (p = 0.042) and 0.728 (p = 0.005), respectively. After excluding patients who received HER2-targeted therapy, patients with HER2-low tumors exhibited better RFS than those with HER2-zero (HR 0.784, p = 0.04), whereas those with HER2-positive tumors exhibited no significant difference compared with those with HER2-low tumors (HR, 0.975; p = 0.953).
Conclusion
Patients with HER2-low tumors had no significant difference in pCR rate compared to HER2-zero but showed better survival, especially in HorR-negative tumors.Further investigation into biological differences is warranted.

Due to rapid westernization, Korean dietary habits have emerged as significant risk factors for chronic disease and cancer. Despite this transition, Korea’s cancer prevention guidelines have remained consistent since their establishment about 18 years ago. This study aimed to investigate the degree of awareness and practice to global dietary guidelines among Korean adults and identify demographic and lifestyle factors associated with low practice. A cross-sectional survey conducted in 2023 included 4,000 adults and assessed their awareness and practice of four global recommendations: “Eat a diet rich in whole grains,” “Limit consumption of processed meat,” “Limit consumption of sugar-sweetened beverages,” and “Limit consumption of fast and other processed foods.” While more than half of the participants recognized the guidelines’ importance for cancer prevention, implementation rates remained below 40%. Furthermore, over 80% of the respondents expressed a compelling requirement for updated and tailored dietary guidelines. Younger individuals, those who were physically inactive, individuals who had not received prior nutrition education, and participants with obesity were more likely to exhibit low practice, particularly to guidelines limiting processed foods and sugary beverages intake. These findings highlight the need to revise Korea’s cancer prevention recommendations by incorporating global dietary practices and addressing the westernized eating patterns prevalent within the population. Efforts should focus on promoting these updated guidelines through targeted education and public health interventions that improve practice, especially in high-risk groups, and effectively mitigate the burden of diet-related cancers in Korea.
