PURPOSE: To assess the indication and effect of screw fixation in the transverse patellar fractures. MATERIALS AND METHODS: We analysed the results of 14 transverse patellar fractures fixed with screws from January 1991 to May 2005. Mean follow-up period was 47 months (range, 12~143 months). We analysed the radiologic union, operation time, ROM and postoperative Lysholm score. RESULTS: All fractures healed uneventfully. The mean displacement was decreased from 2.2 mm preoperatively to 0.3 mm postoperatively (p=0.001, Wilcoxon signed rank test). The mean operation time was 34 minutes (range, 20 to 60 minutes). Normal range of motion was achieved in 13 knees (92.9%). Average Lysholm score was 95.9 at final follow-up. CONCLUSION: Screw fixation seemed to be useful for treatment of transverse patellar fracture even in comminuted fractures with large fragments. The advantage of this technique was the preservation of extensor mechanism, simplicity, short operation time and good cosmesis.

Shigella is a common cause of bacterial enteritis worldwide. Shigella sonnei accounts for 90% of Shigella infections and Shigella flexneri is rarely reported in Korea. Although the incidence of Shigella infection has decreased, the incidence of organisms with antibiotic resistance has gradually increased in Korea. An outbreak of extended-spectrum β-lactamase (ESBL)-producing S. sonnei in children was reported in Korea; however, ESBL-producing S. flexneri has not yet been reported. We report the first two cases of multidrug-resistant CTX-M-14-producing S. flexneri infections in Korean children.

Botulism is a rare neuroparalytic disease caused by neurotoxins of Clostridium species. A ten-year-old girl and her mother were admitted to a hospital with symptoms of progressive dizziness, blurred vision, slurred speech, constipation and difficulty in swallowing. These characteristic manifestations and clinical course prompted an examination of the possibility of botulism. Mouse bioassay performed with mother's stool demonstrated type A botulinum toxin and culture of the mother's stool was positive for Clostridium botulinum type A. This is the first case of botulism in Korea.

PURPOSE: Free radicals are defined as any species capable of independent existence that contains one or more unpaired electrons and they have the effects on carcinogenesis and tumor progression by causing mutations on genetic structure or suppressing repair of mutated DNA. This study was aimed to identify changes of antioxidant capacity in carcinogenesis and tumor progression of colorectal cancer (CRC). METHODS: We studied the level of serum antioxidant capacity using ABTS technique for 34 CRC patients who were operated between July 1997 and January 1998 at department of surgery, Taegu Catholic Medical Center and compared with 38 persons who had normal value of liver function during the same period. RESULTS: CRC patients showed decreased serum antioxidant capacity level compared to that of control group (CRC male 1.23 0.15 mmol/L, CRC female 1.11 0.13 mmol/L, control male 1.40 0.15, control female 1.35 0.11 mmol/L). Changes of antioxidant capacity levels were not correlated with stages, even though the marginal difference between T-stages (T1/2 1.23 0.10 mmol/L, T3/4 1.16 0.15 mmol/L). CONCLUSIONS: Free radicals may be the causative agent of colorectal carcinogenesis and can be associated with early phase of carcinogenesis rather than tumor progression.

Cortical blindness is characterized by visual sensation loss with retention of pupillary reaction to light, and a normal fundoscopic examination. The suggested causes are emboli, profound hypotension, anemia, and infarction of watershed areas in the parietal or occipital lobe. We experienced a case of cortical blindness with severely reduced visual acuity after penile cancer surgery under general anesthesia. In the acute stage, visual acuity was slightly improved, but over the course of several months, no further improvement in visual acuity occurred. In this case there was no severe hypotension or anemia during the operation. Two days after the operation, electroencephalography (EEG) was performed during the period of blindness and the recording obtained was abnormal, with no alpha rhythm. Biparieto-occipital lucency was found by magnetic resonance imaging (MRI). Therefore parieto-occipital infarction due to seizure, embolus, or thrombosis could be considered a possible etiology. We concluded that cortical blindness can unexpectedly develop perioperatively and postoperatively, and that close monitoring of the patient and adequate management are essential.

BACKGROUND: Although the elderly patients who need coronary revascularization are increasing, the effecti- veness and benefit of percutaneous coronary intervention(PCI) or coronary artery bypass surgery(CABG) in the elderly patients have not been evaluated by using comprehensive geriatric assessment. METHODS: From January 2007 to May 2007, 47 patients aged 65 years or older, who had stable angina with more than one coronary artery stenosis, were included in the current study. Comprehensive geriatric assess- ment, including medical, psychosocial, and functional evaluation, was performed by geriatric team. Patients were managed by medical treatment, PCI or CABG according to the decision of attending physician. One year clinical and laboratory evaluations were performed in all the study patients. RESULTS: Baseline characteristics were not significantly different among the medical treatment, PCI, or CABG group, except the extent of coronary artery disease(p=0.007). In addition, comprehensive geriatric assess- ment showed no difference in the three groups. During the follow-up period, major adverse cardiac events (MACE) were observed in 9 patients including 2 cases of cardiac death. Compared with medical treatment and PCI group, CABG group showed impaired ADL status. ADL independency was significantly impaired in CABG group; medical treatment group(84.6%-->91.7%), PCI group(85.2%-->76.9%), and CABG group(71.4%-->33.3%)(p=0.025). However, there was no other difference in cognition, depression, and nutritional status among the groups. CONCLUSION: Compared with medical treatment and PCI group, patients treated by CABG appeared functional dependency in the elderly patients. Effort to identify the risk factor and vulnerable patients should be emphasized especially in the elderly patients who need CABG.

Multilocus sequence typing (MLST) of Salmonella is useful method for replacing serotyping using antisera but is limited by difficulties associated with in polymerase chain reaction (PCR). We optimized the PCR reaction, especially annealing temperature and extension time (94degrees C for 2 min; 40 cycles at 94degrees C for 30 sec, 56.8degrees C for 1 min, 72degrees C for 2 min; and 72degrees C for 10 min). The degradation of PCR product by thermostable nucleases was inhibited by using template DNAs treated proteinase K or purified by a commercialized preparation kit. The resulting modified MLST was used as accurate and fast typing method.

Burkholderia pseudomallei is a gram-negative opportunistic intracellular pathogen that causes an acute and fatal septicemic melioidosis in humans. The organism is mainly found in Southeastern Asia and Northern Australia. Recently, we encountered a case of melioidosis in a Korean patient and performed the laboratory diagnosis of melioidosis. As a result, a gram negative bacterium was isolated from a melioidosis patient, and it was identified as B. pseudomallei on DNA sequencing of 16S ribosomal RNA with 99.9% homology and biochemical examination of VITEK gram-negative identification card. Also, DNA from cultured bacteria was tested in multiplex PCR, a 245 bp fragment amplified from the metalloprotease gene and a fragment of variable size ranging from 400~700 bp resulting from amplification of the 10 bp repetitive element for B. pseudomallei were confirmed after electrophoresis. The bacterium was sensitive to ceftazidime, imipenem and meropenem but resistant to ticarcillin. So far, there are no domestic cases of melioidosis in Korea, however, due to the increase in international travelers, the incidence of melioidosis is likely to increase. We report a recent case of melioidosis in a Korean patient.

PURPOSE: Multiple symmetric lipomatosis (MSL) is a relatively rare disorder characterized by presence of multiple, symmetric, nonencapsulated fat masses in face, neck, shoulder and other areas. There has been only a few cases reported in Korea. The main purpose of this research is to examine the Korean patients to see what kinds of special characteristics occurred due to this disease and to decide the proper treatment. METHODS: A total of 16 patients were evaluated retrospectively. 5 patients were treated at our hospital. The other patients were reviewed from literature. We analyzed the biological characters of patients, location of fat deposit, morphologic characters of patients, clinical evidence of neuropathy, associated metabolic disorders and treatment modality. RESULTS: All cases were male patient. The mean age of onset was 47.43 years. All patients were moderate to heavy alcoholics. The most common location of fat deposition was posterior neck and abdomen. In neurologic exam of 9 patients, 5 patients showed muscle weakness, tremor, pain and autonomic nerve dysfunction. In metabolic studies of 9 patients, total cholesterol values were higher in 1 patient. A glucose tolerance test was abnormal in 1 patient. In treatment modality, 14 patients were treated with surgical resection, 1 patient was treated with liposuction and surgical excision, 1 patient was treated only with liposuction. CONCLUSION: To treat MSL patients successfully, we should concentrate not only on the removal of the fatty tissue but also on neurologic abnormities, metabolic disorders and associated diseases.
