BACKGROUND: Prolonged exposure of topical and systemic corticosteroid to skin can result in well-recognized cutaneous abnormalities including cutaneous atrophy, easy bruisibility, increased skin fragility, and increased risk of infection. Skin barrier impairment is also reported as a steroid-induced side effect. A major function of the skin is the formation of a permeability barrier between the external milieu and the organism. Recent studies have shown that chronic corticosteroid negatively impacts epidermal barrier function. As well as this topical corticosteroid not only has antiproliferative actions but also inhibits the differentiation of the epidermis, resulting in structural defects in the epidermis. OBJECT: We wanted to determine whether high dose systemic steroid injection would display adverse effects, specifically on; epidermal functions, permeability barrier homeostasis and stratum corneum integrity and cohesion. The basis for such changes was also to be determined. MATERIAL AND METHODS: Systemic steroid was administered by injecting each hairless mouse, 8-10 week of age, intraperitoneally with 0.3 mg triamcinolone acetonide, two times per week for five weeks. For the controlled hairless mice, 0.9% normal saline was administered by the same method of injection. Every week, transepidermal water loss (TEWL) was checked and skin biopsies were taken. Skin specimens were prepared for electron microscopy using both 0.25% ruthenium tetroxide and 4% osmium tetroxide postfixation. For light microscopy staining hematoxylin-eosin and ion capture cytochemistry was used. RESULTS: The results were as follows; 1. From about 1 week onwards, high dose systemic steroid usage produced visible cutaneous changes and significantly increased the TEWL in the group of 0.3 mg triamcinolone acetate injected hairless mice compared with the control. 2. Light microscopic observations of the steroid-injected hairless mice showed gradual thinning of the epidermis from about 2 weeks onwards, compared with the control. Loss of stratum corneum was also observed in the steroid injected hairless mice. 3. The ruthenium tetroxide staining of high dose systemic steroid treated specimens revealed that the lipid bilayer was impaired and fragmented from about 3 weeks. Intercellular spaces were widened and the lipid bilayer either disappeared or showed damage when compared with the control. 4. From about 3weeks onwards. electron microscopic studies revealed, not only a marked decrease in the number of lamellar bodies, but also an abnormal transformation of lamellar bodies in the steroid injected hairless mice compared with the control. 5. Throughout the five weeks, the calcium gradient gradually disappeared in the 0.3mg triamcinolone injected hairless mice compared with the control. Consequently, high dose systemic steroid use results in barrier dysfunction and morphological abnormalities.

Primary intestinal lymphangiectasia is a congenital lymphatic disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein losing enteropathy. As a result, generalized edema, hypoalbuminemia, and lymphocytopenia are clinically manifested. We could not find the reason by several examinations. Therefore, we performed double balloon enteroscopy (DBE), and intestnal lymphangiectasia was diagnosed histologically by a biopsy. DBE is a safe and effective method to diagnose small bowel lymphangiectasia. We report a case of primary intestinal lymphangiectasia, which occurred in a 54-year-old male patient with generalized edema and ascites.

Intussusception is seen often in children but relatively few cases occur in adults. In many cases, the etiology of intussusception in adults is a tumor, with adenocarcinoma being the most common tumor in the small intestine. Gastro-intestinal stromal tumor (GIST) is caused by a mutation of the interstitial cells of Cajal, which controls the speed of peristalsis by being involved in the autonomic innervation between the bowel wall and the smooth muscles of the gastrointestinal tract, and is rarely a factor in adult intussusception. We reported a case of a 74-year-old male patient who came to our hospital with hematochezia and was found to have jejunal intussusception from GIST.

Membranous lipodystrophy represents a peculiar type of fat necrosis that is present in patients with various types of skin disease. It is characterized by the presence of microcysts and macrocysts and is lined by amorphous eosinophilic material with a crenelated arabesque appearance. These findings have been associated with lupus erythematosus, diabetes mellitus, erythema nodosum, trauma, etc. We report a case of a 43-year-old woman who had a red to purple asymptomatic indurated plaque, approximately seven cm in diameter and on the left arm. She was a chronic hepatitis B antigen carrier and had hypertension for four years. Histopathology of the biopsied lesion showed transepidermal elimination of altered collagen and elastic fibers, as well as membranous lipodystrophy changes. There were hypertensive vascular changes including lymphohistiocytic infiltration around the vascular wall, swelling of endothelial cells, increased thickness of the vascular walls, and narrowing of the lumen. We report a case showing transepidermal elimination with membranous lipodystrophy. We carefully suggest that the secondary phenomenon of transepidermal elimination was associated with membranous lipodystrophy and degenerate connective tissues.

A 71-year-old man with a history of percutaneous transluminal coronary angioplasty(PTCA) was referred to our clinic with a one-day history of a continuous substernal chest pain radiating to his left shoulder. In retrospect, he experien- ced chest discomfort after eating fish one day before but did not seek medical attention then. An upper gastrointestinal endoscopy was performed. The cause was not visible during the advancement of the endoscope through the eso- phagus, but a small segment of a fish bone protruding from an ulcerative lesion in the lower esophagus was iden- tified while withdrawing the endoscope. The fishbone was immediately removed. A follow-up CT scan revealed pneumo- mediastinum. Now hemodynamically stable, the patient underwent conservative medical treatment including total parenteral nutrition(TPN) and intravenous antibiotic drugs. The patient made complete recovery. We report a case of a 71- year-old male found to have an esophageal perforation from an ingested fish bone, which was managed successfully with conservative treatment. A pertinent literature review is also included.

Perforation of the biliary tree mostly results from injury to the bile duct during surgery or procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and spontaneous bile duct perforation is rare in adults. As the clinical picture varies, early diagnosis and treatment of spontaneous biliary peritonitis is difficult. A 52-year-old male patient presented with abdominal pain and intractable ascites. He already experienced severe abdominal pain 2 months ago and underwent percutaneous pigtail drainage for the ascites at nearby hospital. ERCP showed large filling defect with leakage of contrast media from the mid common bile duct (CBD) into the peritoneal cavity. We performed endoscopic sphincterotomy and extracted CBD stones with basket and balloon catheter. Then fully covered self expandable metal stent was placed in CBD. After the procedure, the symptom was improved and the amount of pigtail drainage from abdominal cavity was dramatically decreased. 6 weeks later, removing the metal stent, there was no more leakage of contrast media into peritoneal cavity. We report a very rare case of spontaneous bile leakage which was successfully managed with placement of metal stent.

BACKGROUND/AIMS: The association between inflammatory markers and the severity of coronary artery disease (CAD) in patients with stable angina pectoris remains controversial. This study explored the relationships between the serum high-sensitivity CRP (hs-CRP) level and severity of coronary atherosclerosis in patients with stable angina. METHODS: The study enrolled 377 stable angina patients (298 males, 79 females) undergoing coronary angiography from June 2006 to August 2010. Based on the coronary angiography results, they were divided into two groups according to the diameter of stenosis (DS): Group I (DS > or = 50%) and Group II (DS < 50%). Multivariate logistic regression was used to examine the relationship between the hs-CRP level (high hs-CRP > or = 3.0 mg/L versus low hs-CRP < 3.0 mg/L) and the severity of coronary stenosis. RESULTS: Group I had higher hs-CRP levels than Group II [median hs-CRP (interquartile range); 0.70 (0.3-1.66) versus 1.11 (0.52-3.41) mg/L, p < 0.001]. After adjusting for major cardiovascular risk factors, a high hs-CRP level was significantly related to the severity of coronary atherosclerosis (OR 1.95, 95% CI = 1.16-3.30). CONCLUSIONS: Our data show that patients with > or = 50% coronary stenosis have higher hs-CRP levels than patients with < 50% coronary stenosis and stable angina. Further study is needed to define the role of hs-CRP in the progression of angina pectoris.

BACKGROUND: Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. OBJECTIVE: To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. METHODS: To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. RESULTS: The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. CONCLUSION: Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.
