Metastatic spinal cord compression is one of the most dreaded complications of metastatic cancer. This type of compression can lead to pain, neurological deficits and a reduction in the patient's quality of life. A case of rapid progression and extension of a metastatic epidural mass from clear cell adenocarcinoma of the kidney in a short period after surgical decompression is reported, along with a literature review.

As breast-conserving surgery (BCS) has become the most common type of breast surgery, oncoplastic BCS has developed in response to improve cosmetic outcomes. Acellular dermal matrix (ADM) has been used as an adjunct to enhance cosmetic outcomes in partial breast reconstruction. This study aimed to evaluate postoperative complications, cosmetic satisfaction, and oncologic safety over a short-term follow-up period. Methods: This retrospective study included 26 patients who underwent BCS at Myongji Hospital between April 2019 and April 2021. All procedures were performed by three surgeons. We reviewed demographic data, histologic grades, tumor-node-metastasis stages, treatment modalities, and survival data based on patient medical records. Results: Of the 26 total patients, 5 developed seromas, which was the most common complication, and one patient experienced red breast syndrome. The incidence of complications per surgeon was less than 25%. The mean satisfaction score for the cosmetic outcome on a 10-point scale was 7.6 ( ± 2.1) as scored by patients and 8.8 ( ± 0.9) as scored by surgeons. Responses regarding cosmetic satisfaction revealed no significant differences among surgeons (p= 0.444). Of the 26 patients, four were lost to follow-up, and the mean follow-up period was 35.2 months. Two patients experienced recurrence, both of whom had regional recurrence with no local recurrence. Conclusion: ADM replacement is a favorable alternative to oncoplastic BCS, in terms of the ease of surgical procedures, minimal complications, and low rates of local recurrence.

Objective:
Conflicting results regarding SOX17 genes and the risk of intracranial aneurysms (IA) exist in the Korean population, although significant positive correlations were noted in genome-wide association studies in European and Japanese populations. Therefore, we aimed to investigate an association between SOX17 gene variants and IA using exome sequencing data.
Methods:
This study included 26 age-gender matched IA patients and 26 control subjects. The SOX17 gene variants identified from whole-exome sequencing data were examined. Genetic associations to estimate odds ratio (OR) and 95% confidence interval (CI) were performed using the software EPACTS.
Results:
The mean age of the IA and control groups were 51.0±9.3 years and 49.4±14.3 years, respectively (p=0.623). Seven variants of SOX17, including six single nucleotide polymorphisms and one insertion and deletion, were observed. Among these variants, rs12544958 (A>G) showed the most association with IA, but the association was not statistically significant (OR, 1.97; 95% CI, 0.81-4.74; p=0.125). Minor allele frequencies of the IA patients and controls were 0.788 and 0.653, respectively. None of the remaining variants were significantly associated with IA formation.
Conclusion
No significant association between SOX17 gene variants and IA were noted in the Korean population. A large-scale exome sequencing study is necessary to investigate any Korean-specific genetic susceptibility to IA.

OBJECTIVE: Brainstem arteriovenous malformation (AVM) is rare and radiosurgical management is complicated by the sensitivity of the adjacent neurological structures. Complete obliteration of the nidus is not always possible. We describe over 20 years of radiosurgical procedures for brainstem AVMs, focusing on clinical outcomes and radiosurgical techniques. METHODS: Between 1992 and 2011, the authors performed gamma knife radiosurgery (GKRS) in 464 cerebral AVMs. Twenty-nine of the 464 patients (6.3%) reviewed had brainstem AVMs. This series included sixteen males and thirteen females with a mean age of 30.7 years (range : 5-71 years). The symptoms that led to diagnoses were as follows : an altered mentality (5 patients, 17.3%), motor weakness (10 patients, 34.5%), cranial nerve symptoms (3 patients, 10.3%), headache (6 patients, 20.7%), dizziness (3 patients, 10.3%), and seizures (2 patients, 6.9%). Two patients had undergone a previous nidus resection, and three patients had undergone a previous embolization. Twenty-four patients underwent only GKRS. With respect to the nidus type and blood flow, the ratio of compact type to diffuse type and high flow to low flow were 17 : 12 and 16 : 13, respectively. In this series, 24 patients (82.8%) had a prior hemorrhage. The mean target volume was 1.7 cm3 (range 0.1-11.3 cm3). The mean maximal and marginal radiation doses were 38.5 Gy (range 28.6-43.6 Gy) and 23.4 Gy (range 18-27 Gy), and the mean isodose profile was 61.3% (range 50-70%). RESULTS: Twenty-four patients had brainstem AVMs and were followed for more than 3 years. Obliteration of the AVMs was eventually documented in 17 patients (70.8%) over a mean follow-up period of 77.5 months (range 36-216 months). With respect to nidus type and blood flow, the obliteration rate of compact types (75%) was higher than that of diffuse types (66.7%), and the obliteration rate of low flow AVMs (76.9%) was higher than that of high flow AVMs (63.6%) (p<0.05). Two patients (6.9%) with three hemorrhagic events suffered a hemorrhage during the follow-up period. The annual bleeding rate of AVM after GKRS was 1.95% per year. No adverse radiation effects or delayed cystic formations were found. CONCLUSION: GKRS has an important clinical role in treatment of brainstem AVMs, which carry excessive surgical risks. Angiographic features and radiosurgical techniques using a lower maximal dose with higher isodose profiles are important for lesion obliteration and the avoidance of complications.

We describe a rare case of pulsed radiofrequency treatment for pain relief associated with meralgia paresthetica. A 58-year-old female presented with pain in the left anterior lateral thigh. An imaging study revealed no acute lesions compared with a previous imaging study, and diagnosis of meralgia paresthetica was made. She received temporary pain relief with lateral femoral cutaneous nerve blocks twice. We performed pulsed radiofrequency treatment, and the pain declined to 25% of the maximal pain intensity. At 4 months after the procedure, the pain intensity did not aggravate without medication. Pulsed radiofrequency neuromodulation treatment on the lateral femoral cutaneous nerve may offer an effective, low risk treatment in patients with meralgia paresthetica who are refractory to conservative medical treatment.
