Sarcoidosis is a rare d:sease in Korea and its association with erythema nodosurn is even rarer. Recently we saw a patient of bihilar adenopathy, who had arthralgia and erythematous nodules of both lower legs. A skin biopsy obtained from the erythematous nodule of the lower leg showed septal panniculitis, consitent with erythema nodosum, and a biopsy from the mediastinal lymph node revealed a pathology consistent with sarcoidosis. This is the first case of Lofgrens syndrome confirmed by histology ir, Korea.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

Gallstone ileus is a well-known complication of cholelithiasis, but is relatively rare. Most ectopic gallstones are located in the small bowel; they are rarely found in the stomach and duodenum. We describe the imaging findings of a case of intragastric gallstone, as well as a case in which duodenal obstruction was caused by a large gallstone (Bouveret's syndrome).

PURPOSE: Regional and local emergency medical centers are supported and evaluated by the government, but local emergency medical facilities have not done very well. This research was started to aid in the improvement of local emergency medical centers by examining the present condition of medical treatment at those facilities and to indentify problems with the primary emergency medical service. METHODS: This research targeted head nurses at the emergency rooms of 42 hospitals out of 48 local emergency medical facilities in Gwangju and Jeollanam-do, who answered our survey, asked them about the actual condition of day and night duty in the emergency rooms, the present conditions of the hospitals and plans for the future development and analyzed the results. RESULTS: 1)Questions about the present conditions of hospitals: An average of 8.2 nurses were working in emergency rooms, 11.9 patients per day visited during the day, and 18.3 at night. Only 5 hospitals had emergency medical specialists, and the most serious problem in the management of emergency rooms was a shortage of proper medical manpower. 2)Questions about day duty:In 34.7% of the cases, specialists on staff were in charge of day-time medical treatment in emergency rooms and 33.3% of the emergency rooms had no workers in charge. There were many cases for which rapid medical treatment was not done when emergency rooms were called out during the days. 3)Questions about night duty: As to the types of night time medical treatment at emergency rooms, general doctors worked with medical specialists on back-up duty in 54.7% of the emergency rooms, medical specialists worked alone in 31.0%, and general doctors worked alone in 14.3%. those in charge of night duty were public health doctors or army surgeons (23.9%), general doctors (28.6%) and physicians (47.5%) who belong to hospitals. 4)Questions about future plans: All of the respondents answered that the present working system in emergency rooms needed to be changed, and 85.7% of them answered that they needed medical specialists who majored in emergency medicine. CONCLUSION: In local emergency medical facilities, specialists on staff were for in charge of day-time medical treatment. There were many cases in which general doctors were on night duty with medical specialists on back-up duty or medical specialists were on duty. Many hospitals needed medical specialists who majored in emergency medical science and plan future improvement in manpower.

Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disease with various underlying pathophysiologic mechanisms which translate to endotypes, in contrast to clinical phenotypes or histological subtypes. Defining endotypes can help clinicians predict disease prognosis, select subjects suitable for a specific therapy, and assess risks for comorbid conditions, including asthma. Therefore, with recent advancement of biologicals in CRS clinical trials, endotyping can be a breakthrough in treating recalcitrant CRS. CRS is caused by dysregulated immunologic responses to external stimuli, which induce various inflammatory mediators from inflammatory cells, including innate lymphoid cells (ILCs) and T lymphocytes as well as epithelial cells. Thymic stromal lymphopoietin (TSLP), interleukin (IL)-25, and IL-33, which are mainly secreted by epithelial cells in response to external stimuli, act on type 2 ILCs and T helper 2 (Th2) cells, inducing IL-4, IL-5, and IL-13. Local immunoglobulin E (IgE) production is also a signature event in nasal polyps (NP). These inflammatory mediators are novel potential therapeutic targets for recalcitrant CRS. This article reviews recent publications regarding endotypes and endotype-based therapeutic strategies in CRS and NP.

PURPOSE: To evaluate dynamic CT features and its clinical courses of eosinophilic hepatic abscess. MATERIALS AND METHODS: Two-phase dynamic CT findings and the clinical courses of 13 pathologically proven cases of eosinophilic abscess were reviewed. All patients showed peripheral eosinophilia, and diagnoses were confirmed by ultrasound-guided biopsy(n=9) or operation(n=4). In two of the four patients who underwent segmental hepatectomy, worms of the species Fasciola hepatica were detected. Follow-up CT scans after treatment with antibiotics or praziquantel were available in seven and eight patients, respectively. RESULT: All hepatic lesions were found ina subcapsular location or in contact with Glisson's capsule around the bile duct. Arterial-dominant phase CT(n=11)demonstrated clusters of ill-defined low density masses without rim enhancement. Late-phase CT(n=13) more clearly depicted clustering lesions with enhancing rims and diminution of the low-density area. Follow-up CT scans aftertreatment with antibiotics(n=7) showed no change in the lesions in three patients and slight shrinkage of the mainmass with additional new lesions in four. On CT scans of nine patients performad after praziquantel therapy, hepatic masses were seen in all patients to be very slightly smaller after improvement of peripheral hypereosinophilia. CONCLUSION: Two-phase dynamic CT features appear to be helpful for the diagnosis ofeosinophilic hepatic abscess in patients with peripheral eosinophilia. Parasitic infestation by Fasciola hepaticafor example, is the presumed cause of such abscesses, though further studies are required.

Leiomyomas of the appendix are rare and most are encountered incidentally during exploration of the abdomen for some other disease, during postmortem examination, or in the course of routine pathologic examinations of surgical specimens. We report here the findings of ultrasonography, CT and surgery of a case of leiomyoma that arose from the appendix; this lesion was pathologically confirmed.
