Ischemic stroke is a serious neurological complication of infective endocarditis. Intravenous tissue plasminogen activator (t-PA), which has only been approved for treatment of hyperacute stroke, has been excluded as an ischemic stroke treatment due to infective endocarditis according to current expert consensus guidelines. Here, we describe a case of a hyperacute stroke patient treated with intravenous t-PA, who was later diagnosed with infective endocarditis.

An epidemiologic investigation was conducted to identify the source of infection and the mode of transmission of typhoid fever outbreak occurred in Ohchun middle and high schools located in Young il Gun, Kyungpook Province from May 21 to Jun 4, 1994. Four out of 13 hospitalized students in three general hospitals in Pohang City were culture positive typhoid fever (Salmonella typhi Group D). Review of the in and outpatient logbooks of the three general hospitals in Pohang City, county health center and local clinics in the vicinity of the Ohchun middle and high schools suggested that the outbreak was confined to the schools. Drinking water source of the schools was two underground water pumps that had no treatment facilities; one in northern end and the other in southern end of the main school building. However, the southern water pump was closed on April 28, 1994 because a recent test for the water revealed E-coli suggesting a possible fecal contamination. Two hundred twenty students stated that they had experienced symptoms related to typhoid fever since April l, 1994 in a self administered questionaire survey of all of the 2, 226 students. Personal interviews with these 220 students were performed to confirm the clinical history together with a rectal swab culture for typhoid fever and Widal test. A total of 39 patients were detected; 15 confirmed cases (culture-positive) and 24 suspected cases (symptom positive with equal to or greater than 1:160 titer of Salmonella O-antibody or 1:320 titer of H-antibody titer in Widal test). The epidemic curve showed a unimodal curve with a peak on the second week(17 May, 1994) and tailed down to the 5th week (22 28 May, 1994). The overall incidence rate of typhoid fever was 1.8 per 100 students; 1.5 (1.6 for male, 1.5 for female) in the middle school and 2. 4 (6. 2 for male, 0. 4 for female) in the high school. When contrasted with the students who did not drink water at all in the school, the relative risks of incidence rate of typhoid fever for the students who drank the underground water of the school, both underground water and water brought from home, or water brought from home only were 55.5, 19.0, and 3.0 respectively. Three classes which had especially high incidence rates of typhoid fever were located in the southern part of the main school building, where the contaminated underground water pump is located. These findings suggested that the source of infection was the contaminated underground water of the school. Both of the two underground water pumps were closed permanently and the public running water was supplied to the schools.

Case-Control Studies*

Vertical and marginal fractures of the patella are uncommon injuries compared with other types of patellar fracture. It's possible that they are more common than supposed, but often remain undiagnosed as acute injuries. Vertical and marginal fractures often results in less acute disability than stellate or transverse fracture and the routine radiographs are often unhelpful. Failure to diagnose acute vertical and marginal fractures of the patella, especially when the fragments are displaced, may result in prolonged disability of the knee and possible development of degenarative changes in the patello-femoral joint later. Twelve patients of the vertical and the marginal patellar fractures treated at St. Mary's Hospital from Feb. 1982 to Dec. 1987 were analyzed in clinical and radiological aspect. The results obtained from this study were as followings. 1. Vertical and marginal fractures had 15.4% of injury rate in all patellar fractures. 2. The fracture and its displacement were always present on the tangential view of the patella. 3. The mechanism of the fracture was s direct blow to the patella in which the affected knee was flexed. 4. The location of the fracture line was related to the degree of the flexed knee at the time of fracture. 5. Large separated fragments of the patella should be accurately reduced with rigid fixation in the rationale of the intraarticular fracture.

A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is unique in that there was a latent period between infusion and development of PRES. We postulate that rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We suggest that neurological symptoms after blood transfusion should be appropriately investigated.

There are many difficult problems of reduction and its maintaining in the treatment of unstable intertrochanteric fractures. Especially, in cases of elderly patients with marked osteoporosis, prolonged immobilization brings more serious complication. In order to solve these problems, in cases of unstable intertrochanteric fractures with large lesser trochanteric fragment, we have carried out anatomical reduction and rigid internal fixation with compression hip screw and additional transfixation screw on posteromedial fragment. The unstable fractures have been convrted into the stable fractures by transfixation screw. We analyzed the 1 1cases with additional transfixation screw and they showed good results in one year follow up.

PURPOSE: To report a rare case of lymphocytic hypophysitis in a 31-year-old woman who presented with gradually progressive bilateral visual loss during the third trimester of pregnancy. METHODS: Ophthalmologic examination revealed best corrected visual acuity of 0.02 OD and counting fingers at 20 cm OS. Pupil examination revealed no relative afferent pupillary defect in either eye and intraocular pressure was normal in both eyes. A visual field test revealed nearly total visual defect sparing superotemporal area OD and total defect OS. An MRI of the head was performed. RESULTS: At the time of transsphenoidal surgery following the patient's delivery, a frozen biopsy of the lesion revealed diffuse lymphocytic infilteration and fibrosis of the pituitary gland consistent with the diagnosis of lymphocytic hypophysitis. Postoperatively the patient was treated for hypopituitarism. At 5 weeks postoperative, her best corrected visual acuity was 1.0 OU, and visual field defects resolved in both eyes. On follow-up by telephone for postoperative 7 months, the patient remained visually asymptomatic. CONCLUSIONS: The clinical presentation of lymphocytic hypophysitis may mimic pituitary adenoma, lymphoma, germinoma, and histiocytosis. The diagnosis should be suspected in any pregnant or postpartum patient with an intrasellar or suprasellar mass.

Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.
