Descending necrotizing mediastinitis is a life-threatening infection originating in the head or the neck and descends into the mediastinum. Even in the era of antibiotics, mortality rate has been reported to be 25~40%. Prompt diagnosis and treatment is mandatory for delayed diagnosis and inappropriate drainage of the mediastinum are the main causes of high mortality. Surgical management ranges from cervical drainage to routine thoracotomy: however, the optimal management still needs to be defined particularly in respect to effective mediastinal drainage. Although posterolateral thoracotomy incision has been considered as a standard approach, potential disadvantages including postoperative pain, risk of wound complication and delayed recovery remain to be concerned. Thoracoscopic approach is an attractive treatment modality as it can provide an excellent exposure with minimal incision and can complete drainage from the mediastinum and the neck in one-staged manner. We describe here two cases of descending necrotizing mediastinitis successfully managed by thoracoscopic drainage.

A hemagglutination(HA)-typing system has been developed for the presumptive identification of enterotoxigenic Escherichia coli(ETEC) possessing the colonization factor antigens(CFA) Seventy-seven E. coli strains from pediatric patients with or without diarrhea were examined for the mannose-resistant(MR) HA or mannose-sensitive(MS) HA of human, bovine, chicken, and guinea pig erythrocytes and their antibiotic resestances. A significant proportion(68%) of the isolates exhibited the HA pattern of NNNN(experssed in the order human/bovin/chicken/guinea pig erythrocytes), and 10% of the isolates exhibited NNSS, known as the pattern about half of enteropathogenic E. coli serogroups produced. Sixty-nine strains(88%) were resistant to one or more antibiotics; 55(80%) were reristant to four or more antibiotics. The strains showed multiple drug resistance were more higher in HA-positive strains(92% of HA-positive strains) than in HA-negative strains(76% of HA-negative strains) and all of the HA-positive strains with human erythrocytes were resistant to 4 or more antibiotics. There were no significant differences between HA patterns and antibiotic resistance in both the strains from the patients with or without diarrhea. In summary, although the causative organisms in cases of diarrhea of this study have not been established, the date herein suggested that ETEC possessing CFA which produce RRRN or NRRN HA pattern was not participated in this diarrhea.

The authors retrospecitviely analyzed the MRI findings of the 8 head-injured patiens who had showed persistent unconsciousness and severe neurologic deficite after trauma. T2-weighted MR images disclosed high signal intensity lesions of various size and shape at lobar white matter and corpus callosum, subcortical gray matter, brain stem, and cerebral cortex, and assisted greatly in understanding the neurologic deficits of the corresponding patients. The lesions were mostly multiple and involved multiple structures. CT's revealed in those patients only small hemorrhages, suspicious low densities, such nonspecific findings as slit ventricles and diffuse brain atrophy, or no abnormality at all. Post-traumatic parenchymatous lesions detected by MR images were either missed or quite underestimated on CT's. MRI was very supeior to CT in the detection and anatomic localization of nonhemorrhagic intraaxial cerebral injuries. especially in the cases of small corical contusions, brainstem and white matter injuries. For the evaluation of the acute posttraumatic patients, CT ios indicated in order to fastly detect intracranial hemagomas which may need emergent surgical evacuation. If CT findings does not explain the neurologic degicits of the patients, especially in the late stage. MRI is indicated. MRI is expected to play a major role in the diagnosis of shear injuries involoving white matter and brainstem where CT has been of little contribution or misleading.

In the paget's disease involving the vertebra, the symptom and sign of compression come from encroachment on the spinal cord due to the enlarging vertebral bodies, pedicles and laminae. The cord compression appears to be preceded by a long insidious period of noncharacteristic clinical symptoms with minor neurologic dysfunction. The lumbar syndrome of Paget's disease is classified according to its severity, clinical findings, biochemical factors and radiologic patterns. The severity of neurologic complication in Paget's disease involving the vertebra varies according to the level involved. The outcome depends on the suddeness of symptom onset and the effectiveness of decompression. We have experienced a case of Paget's disease involving long bones and lumbar spine in 56 year old male patient, in which surgical decompression produced improvement. We report a case of spinal stenosis in paget's disease with brief review of literature.

Injury of the ankle ligaments is one of the most common sports-related injuries. Although there are some debates as to the best initial treatment for an acute tear of a lateral ligament, persistent functional instability of the ankle develops in approximately 20% of patients regardless of the type of initial treatment. In these patients, late reconstruction of the lateral ankle ligaments may become necessary. Among 13 cases which have been operated with Larsen procedure using peroneus brevis tendon from March 1991 to February 1993, the 11 cases followed up over 1 year were examined clinically and radiologically. We introduced the clinical analysis and results with the brief review of the literatures. 1. The indication of surgical treatment was the ankle instability which had differences over 10° in talar tilting angle or over 3mm in anterior displacement compared wit the uninjured site. 2. The postoperative results were 5 cases in excellent and 4 in good. 3. The Larsen procedure was considered a good method to anatomically and simply stabilize both the ankle and subtalar joint and to fix tendon depending on the type of instability.

Coblation devices are now widely used in arthroscopic surgery and they show a very low incidence of intraoperative complications. We experienced a case where the tip of the wand separated and migrated into the posterior knee compartment in an arthrofibrotic knee. The free wand tip was identified and then extricated from the popliteal hiatus of the knee with using C-arm fluoroscopic control. To the best of our knowledge, this is the first report of its kind involving coblation wands. We describe this complication to show that the use of coblation devices can lead to unexpected problems and it is imperative to inspect all instruments before and after each surgical use.
