The origin of the popliteal cyst is the popliteal bursa and frequently combined with the intraarticular lesion. And open excision has been commonly used as a treatment. The authors reviewed 39 cases of popliteal cyst in 38 patients, mangaged with arthroscopic method at Department of Orthopedic Surgery, College of Medicine, Korea University Hospital from June 1989 to July 1993 and the following results were obtained. l. Among 39 cases, 35 cases(89.7%) were associated with intraarticular lesions of the knee joint; 25 cases(71.4%) were chondral injuries, 6 cases(17.1%) were meniscus tear, 2 cases(5.7%) were rheumatoid arthritis and 2 cases were plica syndrome. 2. 20 cases(51.2%) were shown to have the communication between cyst and joint. 3. During operation, position change of the patient and another draping was not necessary. And the blue stained wall enabled authors to remove more completely the popliteal cyst than other conventional operative procedures. 4. Becuase of the short skin incision, the operation time was saved and we were able to recommend early excercise of the knee joint and ambulation. The operative treatment of popliteal cyst with the arthroscopy is the one staged method to excise the cyst and to intervent the combined intraarticular pathology which develop the cyst, and is one of the recommendable method bacause of small skin incision, short hospitalization and early rehabilitation.

Annular pustular psoriasis is a rare variant of the generalized pustular psoriasis characterized by annular lesions with rapidly evolving pustules, associated mild toxicity, and rapid response to therapy. We present a case of annular pustular psoriasis in a 17-year-old male, in whom no previous history of psoriasis was found. The skin lesions were characterized clinically by annular to gyrate erythematous lesions with pinpoint pustules near the periphery on both shoulders, upper arms, and back areas. The histology showed large intraepidermal spongiform pustules. Most of the skin lesions disappeared within 1 week with topical corticosteroid cream.

The number of sedations performed for diagnostic and therapeutic procedures that do not require general anesthesia is increasing. As most sedations are performed by non-anesthesiologists, safety is has become a critical issue in light of recent adverse outcomes reported in the media. To ensure the safety of patients undergoing sedation for minor procedures, standards regarding patient selection, education, drugs, equipment, facilities, sedation protocols, recovery, and monitoring should be developed and publicized as they have been in the US and European countries. Guidelines developed regarding sedation and analgesia are similar and share their most important goal: patient safety. Any barriers that interfere with achieving this goal should be identified and eliminated. A Korean version of sedation guidelines should be developed. Guidelines that have both the clinical integrity of evidence and consideration of the real world should be developed and enforced.

We are reporting a case of 25-year-old male patient with elastosis perforance serpiginosa who showed multipte serpiginous plaques on his neck. Some of the lesions showed hypopigmented, hard, scar-tissue like plaques in the central part. Histologic examination showed hyperplasia and transepidermal elimination of elastic tissue. By electron microscopy, also, we could prove that the elastic fibers were increased in the dermis.

Acute coronary syndrome (ACS) consists of unstable angina, non-ST segment elevation myocardial infarction (NSTEMI), and STEMI. The pathology underlying ACS is acute thrombosis in a coronary artery, which is usually caused by plaque rupture in a mild stenotic lesion. A rupture-prone plaque is known as a vulnerable plaque (VP), although recently the definition of VP has been expanded to include rapidly progressive plaque. Although no single method can predict future cardiac events in mild stenotic lesions, there have been big advances in detecting VP, such as virtual histology-intravascular ultrasound and optical coherence tomography. These techniques look for thin cap fibroatheromas, which is the most common type of VP, characterized by a thin fibrous cap <65 microm, a large necrotic core, and marked macrophage infiltration of the fibrous cap. The recent concept of VP, the methods for detecting VP, and the treatment of VP are discussed.

BACKGROUND: The aim of this study is to evaluate the influence of immunosuppressants on in-hospital mortality from sepsis. METHODS: Using data of the Health Insurance Review & Assessment Service, we collected data from patients who were admitted to the hospital due to sepsis from 2009 to 2013. Based on drugs commonly used for immunosuppression caused by various diseases, patients were divided into three groups; immunosuppressant group, steroid-only group, and control group. Patients with no history of immunosuppressants or steroids were assigned to the control group. To identify risk factors of in-hospital mortality in sepsis, we compared differences in patient characteristics, comorbidities, intensive care unit (ICU) care requirements, and immunodeficiency profiles. Subgroup analysis according to age was also performed. RESULTS: Of the 185,671 included patients, 13,935 (7.5%) were in the steroid-only group and 2,771 patients (1.5%) were in the immunosuppressant group. The overall in-hospital mortality was 38.9% and showed an increasing trend with age. The steroid-only group showed the lowest in-hospital mortality among the three groups except the patients younger than 30 years. The steroid-only group and immunosuppressant group received ICU treatment more frequently (p < 0.001), stayed longer in the hospital (p < 0.001), and showed higher medical expenditure (p < 0.001) compared to the normal group. Univariate and multivariate analyses revealed that age, male gender, comorbidities (especially malignancy), and ICU treatment had a significant effect on in-hospital mortality. CONCLUSIONS: Despite longer hospital length of stay and more frequent need for ICU care, the in-hospital mortality was lower in patients taking immunosuppressive drugs than in patients not taking immunosuppressive drugs.
