1.Cavernous Hemangioma of the Ilium Mimicking Aggressive Malignant Bone Tumor with Increased Activity on 18F-FDG PET/CT.
Korean Journal of Radiology 2013;14(2):294-298
Osseous hemangioma is a benign vascular tumor, and it usually occurs in the vertebrae and the skull. However, hemangiomas of flat bones are rare, and there are very few reports that describe the radiologic findings of osseous hemangioma of the ilium. We report a unique case of large cavernous hemangioma mimicking a chondrogenic malignant bone tumor originated from the ilium in a 22-year-old female. The mass showed stippled calcifications, heterogeneous enhancement with thick septa and enhanced soft tissue components on CT and MR, and also this mass demonstrated heterogeneous 2-fluoro [fluorine-18]-2-deoxy-D-glucose (18F-FDG) uptake on 18F-FDG PET/CT.

Colonic perforation may occur as a complication of diagnostic and therapeutic colonoscopy. The risk factors for perforation after colorectal endoscopic submucosal dissection (ESD) include an inexperienced endoscopist, a large tumor size, and submucosal fibrosis. The mechanisms of perforation include unintended endoscopic resection/dissection and severe thermal injury. Here, we report a case of colon perforation that occurred after ESD with snaring of a laterally spreading tumor. The perforation was completely unexpected because there were no colorectal ESD-associated risk factors for perforation, deep dissection, or severe coagulation injury in our patient.

Myofibroblastoma is a rare benign mesenchymal tumor of the breast. It presents as a well circumscribed, solitary nodular mass, and it has been reported to mainly occur in male patients. To our knowledge, few reports have described the radiologic appearance of myofibroblastoma in the female breast and there has been no report from Korea. We describe the mammographic, sonographic and histologic findings of a case of myofibroblastoma that presented as a well defined mass mimicking fibroadenoma in a 44-year-old woman.

Penile abscesses are rare, but can develop after trauma, injection therapy, or surgery of the penis, or as an unusual presentation of sexually transmitted diseases. We report a case of penile abscess in a 51-year-old diabetic man, presented 9 days after neglected penile fracture following intracavernosal injection therapy and sexual intercourse. Penile ultrasonography and surgical exploration confirmed the physical examination findings of involvement of the corpus cavernosum. The pus culture from the abscess revealed Enterococcous faecalis. The patient was successfully treated by surgical drainage of the abscess and primary closure of the ruptured tunica albuginea.

Purpose:
Atropine is an antidote used to relieve muscarinic symptoms in patients with organophosphate and carbamate poisoning. Nutritional support via the enteral nutrition (EN) route might be associated with improved clinical outcomes in critically ill patients. This study examined the administration of nutritional support in patients undergoing atropinization, including methods of supply, outcomes, and complications.
Methods:
A retrospective observational study was conducted in a tertiary care teaching hospital from 2010 to 2018. Forty-five patients, who were administered with atropine and on mechanical ventilation (MV) due to organophosphate or carbamate poisoning, were enrolled.
Results:
Nutritional support was initiated on the third day of hospitalization. Thirty-three patients (73.3%) were initially supported using parenteral nutrition (PN). During atropinization, 32 patients (71.1%) received nutritional support via EN (9) or PN (23). There was no obvious reason for not starting EN during atropinization (61.1%). Pneumonia was observed in both patient groups on EN and PN (p=0.049). Patients without nutritional support had a shorter MV duration (p=0.034) than patients with nutritional support.The methods of nutritional support during atropinization did not show differences in the number of hospital days (p=0.711), MV duration (p=0.933), duration of ICU stay (p=0.850), or recovery at discharge (p=0.197).
Conclusion
Most patients undergoing atropinization were administered PN without obvious reasons to preclude EN. Nutritional support was not correlated with the treatment outcomes or pneumonia. From these results, it might be possible to choose EN in patients undergoing atropinization, but further studies will be necessary.

BACKGROUND AND OBJECTIVES: Pulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudden death. However we have limited data of pulmonary arterial stent in paediatric population as the treatment of branch pulmonary stenosis. This study aimed at validating the effectiveness and investigating complications of pulmonary arterial stent implantation in a single institution during mid-term follow up period. SUBJECTS AND METHODS: A total of 42 patients (50 stents) were implanted for treating branch pulmonary arterial stenosis. We used cardiac catheterization for comparing diameter after stent implantation directly and lung perfusion scan indirectly. We also investigated any adverse effect relating the procedure. RESULTS: Percent stenosis of stenotic lesions were decreased from 54.1+/-10.7% to 22.8+/-12.5% (p<0.001) and degree of decrement in affected lung perfusion was declined from 22.7+/-8.0% to 10.3+/-9.0% (p<0.001) immediately and lasts during mid-term follow up period. Complication rate relating the procedure was 12% (6 out of 12) and there was no mortality case. CONCLUSION: This series showed immediate and short term effectiveness of pulmonary arterial stent in congenital heart defects. We concluded that percutaneous transcatheter implantation of pulmonary arterial stent was safe and effective during short and mid-term follow up period.

Astrocytes are activated in response to brain damage. Here, we found that expression of Kir4.1, a major potassium channel in astrocytes, is increased in activated astrocytes in the injured brain together with upregulation of the neural stem cell markers, Sox2 and Nestin. Expression of Kir4.1 was also increased together with that of Nestin and Sox2 in neurospheres formed from dissociated P7 mouse brains. Using the Kir4.1 blocker BaCl2 to determine whether Kir4.1 is involved in acquisition of stemness, we found that inhibition of Kir4.1 activity caused a concentration-dependent increase in sphere size and Sox2 levels, but had little effect on Nestin levels. Moreover, induction of differentiation of cultured neural stem cells by withdrawing epidermal growth factor and fibroblast growth factor from the culture medium caused a sharp initial increase in Kir4.1 expression followed by a decrease, whereas Sox2 and Nestin levels continuously decreased. Inhibition of Kir4.1 had no effect on expression levels of Sox2 or Nestin, or the astrocyte and neuron markers glial fibrillary acidic protein and β-tubulin III, respectively. Taken together, these results indicate that Kir4.1 may control gain of stemness but not differentiation of stem cells.

PURPOSE: In this study, we attempted to analyze the effectiveness of the atopic dermatitis camp for primary school students in the Seoul area. METHODS: Seoul city's atopy camp 2010 was conducted 10 times from May 22nd to October 24th for primary school students at an atopy friendly school and their parents. A total of 374 atopic dermatitis patients participated in the camp and questionnaires for 363 were analyzed, except 11 participants who had left several questions unanswered. In a 3-month follow-up survey, 167 participants out of 374 responded to the mailing questionnaire to evaluate the efficiency of the camp. The response rate was 44.7%. RESULTS: Satisfaction with the educational program of the camp was higher for lower grade students than for higher grade students.(P<0.001) Before camp, higher grade students (P<0.001) or students with severe symptoms were more knowledgeable of atopic dermatitis.(P<0.01) After the camp, the higher the grade, the more the knowledge the student had about atopic dermatitis.(P<0.001) Three months after the camp, there was positive change in the lifestyle of atopic dermatitis patients.(P<0.001) CONCLUSION: Knowledge on atopic dermatitis increased and the lifestyle of atopic dermatitis patients was improved due to the camp. Consequently, Seoul city's atopy camp can be utilized as a method to improve the quality of life of atopic dermatitis patients and their family. And Seoul city's atopy camp is expected to be a model for atopy camps in other local communities.
