PURPOSE: To evaluate the relationship between MR changes of the nucleus pulposus and the time interval after traumatic disc herniation. MATERIALS AND METHODS: T2-weighted MR images of 132 patients with back pain and/or sciatica were reviewed. The changes of signal intensity, central cleft and height of the nucleus pulposus were used as criteria of disc degeneration and they were graded as normal, mild, moderate and severe degrees of degeneration. Putting these criteria together we provided integrated grade of degeneration of the nucleus pulposus(grade 0-3). To get the preliminary data for normal and age-related disc degeneration, we measured the disc height by age groups and disc levels and analyzed the realtionship between the age of the patients and the signal intensity, cleft and height in normal disc levels of the 132 patients. In 68 patients of 88 levels disc herniation, we analyzed the relationship between symptom duration and the degree of degeneration. Among these 68 patients we selected 14 patients(16 levels) who were under 30 years of age and had history of recent trauma to minimize data distortion from age related degeneration and ambiguity of initiation point of degeneration. In this group we analyzed the relationship between the time period after traumatic disc herniation and the degree of degeneration. RESULTS: The age of the patient had close relationship with the grade of signal intensity, central cleft, and disc height and grade of degeneration of the nucleus pulposus in normal discs. in 88 levels of herniated discs, the duration of symptom and degree of degeneration showed moderate correlation. In 14 patients of disc herniation who were under 30 years old and had trauma history in recent 2 years, grade 1 disc degeneration occured in average 3.7 months after trauma. CONCLUSION: Although it was difficult to proceed statistical analysis in the last group because of small patients number, the degree of degeneration of nucleus pulposus had close relationship with the duration after traumas or duration of symtoms.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

The purpose of this study is to evaiuate the results of the reconstruction of acetabular bone defect with morselized bone graft and screw fixed hemispherical cup in revision of failed acetabular cup. Thirty four revisions of an acetabular component that had been performed in 34 patients between 1988 and 1993 at SNUH, and had followed more than four years were included in this study. The revised acetabulum was evaluated clinically by Harris hip score and radiologically by evaluating the osseous union, incorporation and resorption of graft, the amount of migration and cup angle change of revised components and periacetabular radiolucency. The mean Harris hip score was improved 52 to 84. All of the bone grafts united by 6.4 months and incorporated by 13.1 months. The graft bone resorption less than onefourth of the initial graft thickness was 91.2% (31 cases). There was no significant difference between pure allograft and allograft mixed with autograft in clinical and radiological results. Of 34 cases, 2 cases (5.9%) required rerevision of acetabulum for aseptic loosening. The two complications, postoperative infection and trochanteric bursitis were managed successfully with conservative methods. The results of the present study confirm the success of revision of the acetabulum with use of a hemispherical component stabilized with multiple small screws and morselized bone grafts filling bone defects.

The appendiceal mucocele is very rare disease of 0.2% incidence. About 24% of patients are asymptomatic and symptomatic patients present with pain in the right lower quadrant of abdomen in 64%, plapable maas in the right lower quadrant of abdomen in 50%, and rarely, melena, hematochezia, anemia, diarrhea, malaise, and abdominal distension. The gastrointestinal bleeding may be presented in the patient with intussusception, but the massive bleeding is generally absent. We report a case of appendiceal mucocele accompanying with gastrointestinal bleeding and review of literature.

Diagnostic ability of duplex Doppler ultrasonography reling on resistive index is limited when clinical symptoms and signs of rejection are subtle or renal dysfunction is caused by other conditions such as urinary tract infection. To investigate the significance in the changes of renal pelvis, a combined analysis of resistive index and ultrasonographic findings in cases of renal pelvis dilatation and mucosal thickening was undertaken. A mean resistive index was calculated from Doppler measurements of the main, segmental and interlobar arteries. The cause of mucosal thickening was retrospectively analysed using the clinical and laboratory findings. Twenty three cases of renal pelvis dilatation and 17 cases of mucosal thickening were found in a total of 159 renal transplantation cases. In 14 of the 23 cases with renal pelvis dilatation, renal function was normal and their mean resistive index was 0.64±0.04. Pelvis and ureter dilatation caused by ureteral stenosis or compression was demonstrated in 6 cases and their mean resistive index(0.72±0.05)was increased. Mucosal thickening of renal pelvis was found in 7 of 32 cases with acute rejection and in 2 of 13 cases with chronic rejection, but their mean resistive index was not different from that of the cases without pelvic mucosal changes Three cases of acute rejection associated with urinary tract infection and 2 cases of chronic rejection in whom resistive indices were indeterminate, but mucosal thickening of the renal pelvis was prominent at ultrasonography. In renal transplant patients having indeterminate resistive index and mucosal thickening of the renal pelvis, ultrasonographic features must be correlated with the clinical and laboratory findings for an accurate diagnosis and treatment of renal dysfunction.

Cryptococcosis is an acute, subacute or chronic infectian caused by the encap sulated yeast Cryptococcus neoformans. The case of Cryptococcosis is a 2 5/12 year-old boy with involvement of the skin, lungs, liver, spleen, lymph node and central nervous system is reported. He has suffered from fever, nausea., vomiting and multiple skin lesions for a month. Thcre were various cutaneous lesions consisting of papules, pustules, nodules, crusts and ulcers on the scalp, face, back, buttocks and both extremities. Diagnosis was confirmed by the clinical characteristics, histopathologic findings and culture of the C. neoformans from cerebrospinal fluid and marcerated skin tissue. He was successfully treated with combination of Amphotericin B and 5-fluorocytosine.
