PURPOSE: To evaluate efficacy and the safety of percutaneous catheter drainage in patients with pneumothorax that is difficult to treat with closed thoracotomy. MATERIALS AND METHODS: We retrospectively reviewed effectivenss of percutaneous catheter drainage (PCD) in 10 patients with pneumothorax. The catheter was inserted under fluoroscopic guidance. Seven patients had spontaneous pneumothorax caused by tuberculosis (n=4), ruptured bullae (n=2), and histiocytosis-X(n=l). Three patients had iatrogenic pneumothorax caused by trauma (n=l) and surgery(n=2). All procedures were performed by modified Seldinger's method by using 8F-20F catheter. RESULTS: All catheters were inserted successfully. In 9 of 10 patients, the procedure was curative without further therapy. Duration of catheter insertion ranged from 1 day to 26 days. In the remaining 1 patient in whom multiple pneumothorax occurred after operation, catheter insertion was performed twice. CONCLUSION: Percutaneous catheter drainage under fluoroscopic guidance is effective and safe procedure for treatment of pneumothorax in patients with failed closed thoracotomy.

PURPOSE: To determine the characteristic CT findings of infectious sacroiliitis and ankylosing spondylitis. MATERIAL AND METHOD: We retrospectively reviewd CT findings in 10 patients with infectious sacroiliitis confirmed by culture and clinical follow ups and in 5 patients with ankylosing spondylitis by HLA-B27 typing. Mean ages were 30 years in ankylosing spondylitis and 29 years in infectious sacroiliits. CT scans were obtained with GE 9800 or Toshiba 900-S scanner. We analyzed CT findings in regard to the morphology and the degree of bone erosion, and the adjacent soft tissue change. RESULT: All cases of ankylosing spondylitis had bilateral and asymmetic bone erosion, predominantly in ilium, showing subchondral sclerosis on ilium. Infectious sacroiliitis showed unilateral involvement and soft tissue swelling in 10 cases and abscess in 5 cases. CONCLUSION: We concluded that CT was useful in the differentiation between infectious sacroiliitis and ankylosing spondylitis.

Background/Aims: Despite proper use of pharmaceuticals, adverse drug reactions (ADRs) can lead to problems related to patient safety. We analyzed the characteristics of ADRs, particularly serious adverse events (SAEs), in a single tertiary medical institution. Methods: Spontaneous ADR report data collected from 2010 to 2019 in Seoul National University Hospital were assessed. Causality was evaluated according to the World Health Organization-Uppsala Monitoring Centre criteria. Age, sex, onset, severity, seriousness, and system organ class (SOC) of ADRs and SAEs were analyzed. Results: During the study period, a total of 49,955 individual case safety reports were assessed as possible, probable, or certain. Although the number of gastrointestinal ADR reports was high (25.9%), severe cases were uncommon (2.6%). By contrast, the number of hematologic disorders was low (6.6%) but 39.2% of them were severe. Among ADRs, 10.2% were assessed as SAEs, the proportion of which was high at extreme ages and in males. Body as a whole-general disorders were the most frequently reported SOC for SAEs, followed by skin and appendage disorders. Antineoplastic agents and antibiotics were the most common causative agents of SAEs and ADRs. Anaphylactic reaction was the most frequent SAE (6.5%). Conclusions The proportion of SAE differs according to SOC and drug. Attention should be paid to SAEs in children and older adults because the rate of SAEs is significantly higher at extreme ages.

Syringomas are common benign adnexal tumors, probably of the eccrine origin. They are more common in women and usually found around the eyelids. An exclusively acral site of the lesions is very rare. We present a case of acral syringomas in a 44 year-old woman, involving only the dorsum of the fingers of both hands. It is important to include syringomas in the clinical differential diagnosis of papular lesions of the hands.

Oral allergy syndrome (OAS) is a subtype of food allergy composing of itching sense and edema in the oral cavity, lips, throat, pharynx, and larynx following ingestion of some fresh fruits or vegetables. Although the major pathogenic mechanism of OAS is known to be IgE-mediated response, here we experienced a case of OAS due to crown daisy (CD) and sesame leaf (SL) mediated by a non-IgE antibody mediated mechanism. A 33-year-old female visited our clinic to evaluate numbness of the tongue and gingiva after eating fresh CD and SL for 2 years. The patient had suffered from allergic rhinitis and atopic dermatitis for 20 years and took medications intermittently. There had been a history of food allergy to crab and shrimp. The serum total IgE level was elevated (404 kU/mL). The skin prick test showed strong positive reactions to tree and weed pollens, but not to CD and SL extracts. Enzyme-linked immunosorbant assay for detecting serum specific IgE to crude extracts of CD and SL showed negative results. The basophil activation test performed with crude extracts of CD or SL showed significant up-regulation of CD63-positive basophils by both CD and SL. In conclusion, we report a case of OAS due to CD and SL, not associated with pollen allergy, which is shown to be mediated by a non-IgE mediated mechanism.

Pyoderma gangrenosum (PG) is a rare and painful skin disease, frequently associated with underlying systemic conditions, such as inflammatory bowel disease or hematological malignancy. PG is generally classified into 4 types: classic (ulcerative), bullous, pustular, and vegetative. Pustular PG is an uncommon variant of PG that the pustules do not progress to form ulcers. We report a case of pustular PG, which was successfully treated with infliximab and topical tacrolimus, in a 28 year-old Korean man with ulcerative colitis.
