Esophageal ulcers induced by doxycycline is a rare complication. These patients usually complain of sudden onset of symptoms, ie acute substernal or chest pain and odynophagia without prior hietory of esophageal syraptoms. On esophagoscopic examination, there are upper or midesophageal ulcers, which heal after diseontinuation of the drug within 2 weeks. A history of ingestion of the doxycycline,with liquid jost before bedtime can be elicited. The exact eause of the xaucosal ulceration is not clear, but a direct irritant effeet on esophageal mucosa seems most likely. We report 5 cases of esophageal uleeration secondary to the ingestion of doxycydine. Esophagoscopy revealed esophageal ulcers in all patients and the patients hecame asymptomatic following stopping of tbe drugs and taking antacids.

The tibial plateau fracture is a common fracture in the knee joint. Tibial plateau fracture involves most always the articulating cartilage and produce the disability of the knee joint oftenly. The 25 cases of tibial fractures have been classified by Hohls method and analysed their clinical courses more than three month period. The 13 cases out of 25 had treated in conservative method such as plaster of Paris with or without closed reduction. Remaining 12 cases were treated operatively due to the failure of closed reduction or associated injury of major ligaments. More than 8 mm of depression or 5 mm split of the plateau fragment is classified as failure of closed reduction. Excellent end result is obtained in 21 cases with free of pain on walking and full range of joint motion without instability and muscle weakness, Three cases were classified as Good result with occasional pain on walking, range of joint motion is available more than 0~90 degree and good grade of muscle power without instability. One case was poor in result with instability of joint and pain on walking. The radiological end result of accurate reduction of fragment is not closely correlated with functional result in the treatment of tibial plateau fracture. The most important factor in the treatment of tibial plateau fracture is the exercises of the joint as early as possible.

Renal cell carcinoma is an uncommon tumor in children and its prognosis is better in children than in adult one. This report describes two cases of renal cell carcinoma our Severance hospital and includes review of literatures. it children that were confirmed pathologically at All of them took place in 9 year old girls and they presented only gross hematuria without palpable mass or flank pain.

Hepatocellular carcinoma (HCC) have relatively well known causative factors such as chronic hepatitis B, chronic hepatitis C, alcoholic liver disease, Non-alcoholic fatty liver disease (NAFLD), liver cirrhosis and so on. Recently, interesting reports that HCC in the absence of cirrhosis or other chronic liver disease and HCC associated with NAFLD and metabolic syndrome are increasing in USA. So far, there is no report about these issues in Korea. We present a 65 year-old obesity male who had no preceding chronic liver disease history. He was diagnosed as primary HCC and the mass was removed completely. However, HCC recurred shortly after operation. Multiple recurred HCC were treated with transcatheter arterial chemoembolization.

Hantaviruses are members of the family Bunyaviridae, the etiologic agents of Hemorrhagic fever with renal syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS). They are negative-sense, single-stranded RNA viruses possessing a large (L), medium (M) and small (S) genomic segment which encodes a viral polymerase, envelope glycoproteins (G1 and G2) and a nucleocapsid (N) protein, respectively. Seoul (SEO) virus, the causative agent of clinically mild HFRS in worldwide, was isolated from lung tissues of urban rat (Rattus norvegicus) captured in Seoul, Korea, 1982. To clarify the antigenic characteristics and the differentiation of serotypes of hantavirus, 8 hybridoma cell lines secreting monoclonal antibodies (MAbs) against SEOV 80-39 strain were produced by fusion of SP2/0-Ag14 mouse myeloma cells with spleen cells of BALB/c mice, immunized with SEOV. Reactivities of these MAbs were examined by the indirect immunofluorescence assay (IFA), enzyme linked immunosorbent assay (ELISA), immunoblot, high density particle agglutination (HDPA) and plaque reduction neutralization test (PRNT). Eight out of 235 hybridomas secreted MAbs of Seoul virus 80-39 continuously, and these eight MAbs were all IgG. The isotypes of these 8 MAbs are; one clone (F3-3C) was IgG1, six (F1-1B9B, F1-3B, F1-3D, F4-1E, F4-3F, F4- 6C) were IgG2a and one (F1-1B9F) was IgG2b. Seven MAbs (F1-1B9B, F1-1B9F, F1-3B, F1- 3D, F3-3C, F4-1E, F4-3F) reacted with nucleocapsid protein (M.W. 50K) of SEOV by immunoblot. All eight MAbs were cross-reacted with Hantaan (HTN) virus, one (F4-3F) was cross-reacted with Puumala (PUU) virus and two (F1-1B9B, F1-3B) were cross-reacted with Prospect Hill (PH) virus by IFAT. None of these 8 MAbs had neutralizing activity.

PURPOSE: Erectile dysfunction (ED) may be considered as a clinical manifestation of generalized vascular disease. This study aimed to assess the correlation between ED and the severity of the involved coronary artery in patients with coronary artery disease (CAD). MATERIALS AND METHODS: 255 men with CAD, who underwent coronary angiography (CAG), were evaluated for erectile function using a questionnaire that included a 5-item Version the International Index of Erectile Function (IIEF-5). Cardiovascular risk factors were also reviewed. The correlation between erectile function and the number of involved coronary vessels, age and number of accompanying cardiovascular risk factors were analyzed. RESULTS: Of the patients, 59.6% had various degrees of ED, which were subdivided into mild (21.7%), moderate (14.5%) and complete (63.8%) according to the severity. The cardiovascular risk factors were hypertension, smoking, overweight, age, lipid abnormalities and diabetes in 67.8, 67.5, 47.1, 38.4, 28.6 and 19.6%, respectively. One, two and three coronary vessels were involved in 26.3, 27.4 and 21.2%, respectively, while 25.1% showed non specific finding on CAG, despite abnormal findings in the resting ECG and treadmill exercise test. Erectile function decreased significantly according to the increasing number of involved coronary vessels (p<0.05), age (p<0.001) and accompanying cardiovascular risk factors (p<0.05). Of the cardiovascular risk factors, age, smoking and diabetes had negative effects on erectile function (p<0.05) in patients with CAD. CONCLUSIONS: Statistically significant correlations were demonstrated between ED and the number of involved coronary vessels, age and the number of accompanying cardiovascular risk factors in patients with CAD. Furthermore, in patients with symptoms of chest discomfort, although CAG showed non specific findings, the possibility of hidden ED will need to be investigated.
