Gastric volvulus, organoaxial or mesenteroaxial rotation, is an uncommon cause of uper gastrointestinl obstruction in childhood. It may be suspected on plain radiographic examination of the abdomen and confirmed by upper gastrointestinal series. Six affected children are described. Symptoms wer3e mainly acute vomiting and abdominal distension. All patients had defect in perigastric ligaments.

Castleman disease is a rare disease entity of unknown etiology, with the characteristics of large, well marginated benign lymphoid masses occuring predominently in the mediastinum. The value of contrast enhancement in solid soft tissue masses of mediastinum has little been written because most of the solid mediastinal tumors show no significant degree of enhancement. But Castleman disease, because of its hypervacularity, show significant degree of enhancement in most cases. Authors report 3 cases of Castleman diseases and suggests good diagnostic probability of CAstleman disease in cases that show benign looking homogeneously enhancing mediastinal mass by CT scan.

The fluroscopically controlled foley catheter technique is an easy, safe, and successful method of removal of blunt esophageal foreign bodies such as coins, and avoids the risks of general anesthesia and endoscopy. AAuthors successfully removced four coins and one baduk-stone which obstructed upper esophagusm using Foley cathether technique at Seoul National Univ. Children's Hospital from November 1986 to April 1987.

김상은,정호성,이근,한헌 大韓應急醫學會 1992 대한응급의학회지 Vol.3 No.1
Four slices of chest CT(CCFS) are applicated for the patients with blunt chest trauma, at the Emergency Medicine Department of Chungang Gil Gerenal Hospital. Authors analyzed the findings of plain film & CCFS of 53 patients, who visited our department with the chief complaint of blunt chest trauma from April 1992 to October 1992. CCFS shows more information than plain film, as expected. CCFS shows 15 cases(28%) of hemothorax, 5 cases(10%) of pneumothorax and 7 cases(8%) of lung contusion. Plain film shows 4 cases(8%) of hemothorax, 2 cases(4%) of pneumothorax and 4 cases(8%) of lung contusion. In conclusion, CCFS is a useful tool for the evaluation of blunt chest trauma

To evaluate the relationship between response categories assessed by magnetic resonance imaging (MRI) or pathology and survival outcomes, and to determine whether there are prognostic differences among molecular subtypes. We evaluated 174 patients with biopsy-confirmed invasive breast cancer who had undergone MRI before and after neoadjuvant chemotherapy, but before surgery. Pathology findings were classified as a pathologic complete response (pCR) or a non-pCR, and MRI findings were designated as a radiologic CR (rCR) or a non-rCR. We evaluated overall and subtype-specific associations between clinicopathological factors including the assessment categories and recurrence, using the Cox proportional hazards model. There were 41 recurrences (9 locoregional and 32 distant recurrences). There were statistically significant differences in recurrence outcomes between patients who achieved a radiologic or a pCR and patients who did not achieve a radiologic or a pCR (recurrence hazard ratio, 11.02; p = 0.018 and recurrence hazard ratio, 3.93; p = 0.022, respectively). Kaplan-Meier curves for recurrence-free survival showed that triple-negative breast cancer was the only subtype that showed significantly better outcomes in patients who achieved a CR compared to patients who did not achieve a CR by both radiologic and pathologic assessments (p = 0.004 and 0.001, respectively). A multivariate analysis found that patients who achieved a rCR and a pCR did not display significantly different recurrence outcomes (recurrence hazard ratio, 2.02; p = 0.505 and recurrence hazard ratio, 1.12; p = 0.869, respectively). Outcomes of patients who achieved a rCR were similar to those of patients who achieved a pCR. To evaluate survival difference according to molecular subtypes, a larger study is needed.

Purpose: To assess long term results of excising benign masses using ultrasound (US)-guided, vacuum-assisted core biopsy (Mammotome). Materials and Methods: We enrolled 163 patients (197 masses) receiving USguided excision using vacuum-assisted core biopsy and follow-up sonography in this retrospective study. The masses were category 3 as determined by ultrasound imaging according to the Breast Imaging Reporting and Data System (BI-RADS) (n=145)or pathologically confirmed as benign masses by a previous core-needle biopsy although category 4a and 4b (n = 52). Pathology, the presence of hematoma and residual tissue, as well as scar formation were assessed. Results: We diagnosed 190 (96.5%) benign masses, 4 (2.0%) malignant masses,and 3 (1.5%) high-risk lesions. Most (176 masses, 91.2%) were excised completely as demonstrated by the follow-up ultrasound examination. Scar changes were minimal (68.7%) or moderate (31.3%), with regression in 53%. Conclusion: US-guided excision using vacuum-assisted core biopsy is effective for the removal of benign breast masses. The majority of scars are minimal, with good cosmetic effect. However, subsequent excision should be done for malignant masses or phyllodes tumor because radiologic absence does not guarantee complete removal. 목적: 양성 유방 병변에 대한 초음파 유도 하 진공흡입종괴제거술 후 장기 추적 검사 결과와 그 효율성에 대해 알아보고자 한다. 대상 및 방법: 후향적 연구로 초음파 유도 하 진공흡입종괴제거술을 시행하고 추적 초음파를 시행 받은 163명의환자의 197개의 병변을 대상으로 하였다. ACR BIRADS에근거하여 145개의 병변은 카테고리 3으로, 52개의 병변은 초음파상 카테고리 4a, 4b로 판단되었지만 초음파 유도 하 진공흡입 종괴제거술 전에 시행한 코아생검법 (core needle biopsy)에서 양성으로 판명되어 대상 군에 포함시켰다. 병리 결과를 살펴보았고, 초음파 유도 하진공흡입 종괴제거술의 효율성을 알아보기 위하여 혈종의유무, 잔류 병변 여부를 분석하였다. 초음파 유도 하 진공흡입 종괴제거술 절제 부위의 반흔성 변화를 시사하는 저에코성 병변도 분석하였다. 결과: 190개의 양성 병변 (96.5%), 4개의 악성 병변(2.0%)과 3개의 고위험병변 (1.5%)이 병리학적으로 진단되었다. 197개의 병변 중에 178개의 병변 (90.4%)이완전히 제거되었음을 추적 초음파를 통하여 확인하였다. 초음파 유도 하 진공흡입 종괴제거술 후의 반흔성 변화는최소 변화 (68.7%)와 중등도 변화 (31.3%)로 구별되었으며 53%에서 반흔성 변화를 시사하는 저에코성 병변의크기가 줄어들었다. 결론: 초음파 유도 하 진공흡입 종괴제거술은 양성 유방병변 제거에 효과적이다. 대부분의 반흔성 변화는 최소변화로 좋은 미용적 효과를 보였다. 하지만 영상 검사로 보이는 완전 절제 소견이 병리적인 완전 절제를 보장하지 않으므로, 악성 병변이나 엽상종의 경우에는 외과적 절제를 다시 시행하는 것이 바람직하다.
