Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

A case of renal amyloidosis with crescentic glomerulonephritis associated with rheumatoid arthritis is described. A 60-year-old female with 15 years' history of rheumatoid arthritis developed nephrotic syndrome followed by rapid deterioration of renal function. Glomerular amyloid deposition and sclerotic change was present in kidney biopsy specimen and crescentic change was found in 85% of the glomerulus. Electron microscopic finding of glomerulus showed randomly oriented, rigid-appearing, long nonbranching fibrils. The patient was treated with intravenous high-dose methylprednisolone pulses combined with intravenous cyclophosphamide followed by oral corticosteroids. Three months after the above treatment, renal function gradually improved, reaching serum creatinine level to 2.5 mg/dL. But the nephrotic range proteinuria persisted.

We report a case of male infertility secondary to pituitary apoplexy, which occurred as a sequela of korean hemorrhagic fever. A 32 years old male patient with past history of korean hemorrhagic fever was studied because of infertility and erectile impotence. The size of his testicles were about 8ml in Rt. and Lt. Semen analysis, endocrinologic studies, and brain MRI demonstrated hypogonadotrophic hypogonadism due to panhypopituitarism. The patient was treated with HCG (2,000 IU) administered intramuscularly three times per week for 6 months. After the treatment, improvement of male secondary sex characteristics such as hair growth and testicle size was noted. Promotion of sexual potency and improvement of semen quality were also noted. Following the treatment, his wife conceived after 6 months.

PURPOSE: We aimed to determine whether head elevation during combined spinal-epidural anesthesia (CSE) and Caesarean section provided improved hemodynamics and appropriate sensory block height. MATERIALS AND METHODS: Forty-four parous women undergoing CSE for elective Caesarean section were randomly assigned to one of two groups: right lateral (group L) or right lateral and head elevated (group HE) position, for insertion of the block. Patients were positioned in the supine wedged position (group L) or the left lateral and head elevated position (group HE) until a block height of T5 to light touch was reached. Group HE was then turned to the supine wedged position with maintenance of head elevation until the end of surgery. Hemodynamics, including the incidence of hypotension, ephedrine dose required, and characteristics of the sensory blocks were analyzed. RESULTS: The incidence of hypotension (16 versus 7, p=0.0035) and the required dose of ephedrine [24 (0-40) versus 0 (0-20), p<0.0001] were greater in group L compared to group HE. In group L, the time to achieve maximal sensory block level (MSBL) was shorter (11.8+/-5.4 min versus 20.1+/-6.3 min, p<0.0001) and MSBL was also higher than in group HE [14 (T2) versus 12 (T4), p=0.0015]. CONCLUSION: Head elevation during CSE and Caesarean section is superior to positioning without head elevation in the lateral to supine position, as it is associated with a more gradual onset, appropriate block height, and improved hemodynamics.

Nonpalpable breast abnormalities which require excision and biopsy usually require marker localization. Many of these abnormalities are visible on ultrasound and this imaging technique can be used to guide fine needle aspiration and the placement of a wire marker prior to surgical excision. A non-invasive technique which does not require placement of a wire marker would offer significant advantages, being more pleasant for the patient and less demanding on resources. We attempted to localize 36 nonpalpable breast masses with non-invasive ultrasound marker technique at the department of general surgery, Soon Chun Hyang University Hospital, between January 1994 and February 1995. Cases clearly visible on ultrasound, whether on mammography(15 patients) or not(17 patients), underwent non-invasive ultrasound localization. In all cases the abnormality was easily identified and removed during surgery. The surgical biopsies contained fibroadenoma(19 cases), fibrocystic disease(12 cases), epithelial hyperplasia(1 case), intraductal papilloma(1 case), parasitic disease(1 case) and infiltrating ductal carcinoma(2 cases). The average age was 43 years old.. This non-invasive technique is a simple and accurate method for localizing small ultrasonically visible nonpalpable breast abnormalities, especially in younger female patient with dense breast, though further trials and studies will be attempted.

The effects of different grades of running on esophageal motility and gastroesophageal reflux in the fed state were evaluated. We studied healthy volunteers (male: 12, age: 27+/-5 yr) using ambulatory esophageal manometry, pH catheter and portable digital data recorder. Each exercise was performed 30 min after meal, with 20 min of rest between exercises. Subjects exercised on a treadmill at 40% and 70% maximal heart rate. The number of gastroesophageal reflux episodes, the duration of esophageal acid exposure and percent time pH below 4 were significantly (p<0.01) increased during exercise at 70% maximal heart rate. The frequency of contraction (contraction/min) (p<0.05), frequency of repetition (p<0.01), percent of simultaneous contraction (p<0.01), percent of above 100 mmHg amplitude (p<0.05), and frequency of 2-peak contraction (p<0.01) were significantly increased during exercise at 70% maximal heart rate. However, median amplitude and median duration showed no significant changes between each exercise session. Postprandial running exercises induce gastroesophageal reflux, which correlates with exercise intensity. These effects are mediated by disorganized esophageal motility.

Bovine borreliosis, caused by Borrelia theileri which is transmitted via hard tick bites, is associated with mild clinical symptoms, such as fever, lethargy, hemoglobinuria, anorexia, and anemia. Borrelia theileri infects various animals, such as cattle, deer, horses, goats, sheep, and wild ruminants, in Africa, Australia, and South America. Notably, no case of B. theileri infection has been reported in Korean cattle to date. In this study, 101 blood samples were collected from a Korean indigenous cattle breed, among which 1.98% tested positive for B. theileri via nested PCR. The obtained sequences exhibited high homology with B. theileri strains identified in other regions. Phylogenetic analysis of 16S rRNA confirmed the B. theileri group affiliation; however, flagellin B sequences exhibited divergence, potentially due to regional evolutionary differences. This study provides the first molecular confirmation of B. theileri infection in Korean livestock. Further isolation and nucleotide sequence analyses are necessary to better understand the presence of B. theileri strains in cows in Korea.
