Angioimmunoblastic lymphadenopathy (AILD) is a systemic disease clinically characterized by fever, generalized lymphadenopathy, hepatosplenomegaly, polyclonal gamma-globulinemia and Cooms' positive hemolytic anemia. The lymph node in AILD reveals a polymorphic feature consisting of a proliferation of small vessels, immunoblasts and plasma cells and acidophilic interstitial material. Progression into immunoblastic sarcoma is reported as high 35% of the patient with AILD. Nathwani et al have observed not only malignant transformation of AILD in sequential tissue examination, but also the coexistence of AILD and immunoblastic lymphoma in the same lymph node or at different sites in the same patient. Multiple clusters or islands of compactly arranged large lymphoid cells constitute the initial histologic evidence of immunoblastic sarcoma. Immunoblastic sarcoma is a large cell lymphoma conceptually related to transformed T-and B-lymphocytes of the extrafollicular compartment of the immune system, which proignosis is poor. We have recently experienced a case of immuno blastic sarcoma arising in angioimmunoblastic lymphadenopathy in a 24-year-old woman. She had history of multiple enlarged lymph nodes in the inguinal, axilla and supraclavicular areas. Previous lymph node biopsies revealed reactive change. Six month later, right axillary lymph node biopsy reveled AILD with focal clusters of immunoblasts. Subsequent lymph node biopsy at the same site revealed diffuse immunoblasic sarcoma, B-cell type. A case presentation with histologic findings and a brief review of literature were done.

PURPOSE: To compare the results of IM nailing of femur shaft fractures using trochanteric and piriformis fossa entry portal. MATERIALS AND METHODS: 37 patients were treated with IM nail using Trochanteric (Trochanter group: TG, n=17) and piriformis fossa entry portal (piriformis group: PG, n=20) and were followed from February 2004 to 2007. The outcomes were assessed based on the clinical and radiographic findings. RESULTS: The functional result, ROM and union time were similar in both groups. The alignment was similar in both groups but PG showed variable alignment in proximal 1/3. Incision was larger in PG (PG=8.7 cm, TG=5.8 cm, p<0.05) and there was a difference between overweight and normal weight group. Operative time was 95 minutes in PG, 87 minutes in TG (p>0.05), there was statistically significant difference in overweight groups (PG=125 minutes, TG=90 minutes, p<0.05). Blood loss was 313 cc in PG, 268 cc in TG and less in TG in overweight patients (p<0.05). There was 5.7degrees of varus angulation in PG, 2 nonunion cases in both groups. CONCLUSION: The femoral nail specially designed for trochanteric insertion resulted in high union rates, low complication rates similar to conventional nail and the trochanteric nail can be the alternative choice especially in proximal femur fracture and overweight patients.

STUDY DESIGN: A retrograde study of metal failures at thoracolumbar spinal fractures fixed using pedicle screws. OBJECTIVES: The predictability and usefulness of the McCormack's classifications for metal failures was compared with Magerl's classifications. SUMMARY OF LITERATURE REVIEW: The load sharing classification was introduced to predict metal failure after short-segmental pedicle screw fixation by McCormack. However, its reliability is uncertain. MATERIALS AND METHODS: From July 2000 to July 2003, this study examined the plain radiographs and CT images of 31 out of 46 patients who underwent posterior stabilization using pedicle screws for thoracolumbar fractures and could be followed up at least 1 year. Fractures were classified utilizing Denis's, Magerl's, and McCormack's systems. RESULTS: As a result of analysis of relation between metal failure and classification system by Magerl or McCormack, there was no significant difference in its distribution. There was no correlation between the fixation range and metal failures in type C3 fractures, but there was a correlation between short fixation and metal failures in rotational burst fractures in short fixation. CONCLUSIONS: In order to prevent metal failures after fixing thoracolumbar spinal fractures by pedicle screws, the stability should be evaluated using Magerl's classification and McCormack's total score. In addition, in cases of type C3 fractures according to the Magerl's classification, reconstructions should be carried out with a long segment fixation or anterior supporting bone grafts, particularly when McCormack's total score is greater than 7.

BACKGROUND: There are few epidemiological studies on patch test with additional batteries in Korea. OBJECTIVE: We report the results of patch tests with additional batteries which are relatively uncommonly used in contact dermatitis patients. METHODS: Standard patch testing was performed with Finn chamber on Scanpor tape. We used additional batteries including cosmetic and fragrance series which are commonly used, and the others including 14 batteries(so-called ""other"" batteries). RESULTS: Over the last 8 years, 719 patients (male 184, female 535) were tested in our contact, dermatitis clinic. 178 patients (24.8%) were tested with both Standard and other batteries, In other batteries, rubber additive series were most frequently used (9.2%), and textile colours finish (4.3%) and hairdressing series (3.6%) were used in order of frequency. Rarely performed batteries were (meth) acrylate ser ies, photographic chemicals series, wood set, oil & cooling fluid series, and various allergens. Patients tested with steroid batteries did not show positive reactions. CONCLUSION: We suggest that 6 batteries ((meth)acrylate series, photographic chernicals series, wood set, oil & cooling fluid series, various allergens, steroid battery) have law testing frequencies and positive rates. A more organized multicenter study is required.

OBJECTIVE: The aim of this study was to explore the reliability and validity of the Korean version of the Cornell Scale for Depression in Dementia (CSDD-K), a scale for assessment of depression in dementia. METHODS: The original CSDD was translated into Korean and the content was verified through back-translation procedures. This study included 59 depressive patients with Alzheimer's disease (AD), 62 non-depressive patients with AD and 36 healthy elderly controls. The subjects were assessed using CSDD-K, the 17-item Hamilton Depression Rating Scale (HAM-D17), the 15-item Korean version of Geriatric Depression Scale (GDS15) and the Korean version of Mini-mental Status Examination (MMSE-K). RESULTS: In the reliability test, Cronbach's alpha coefficient and test-retest reliabilities were 0.92 and 0.91, respectively, indicating that the CSDD-K has good internal consistency. There were significant differences in CSDD-K total scores between AD patients with depression and AD patients without depression (p<0.001). In the analysis of the concurrent validity of the CSDD-K, there were significant correlations between the CSDD-K and HAM-D17 (r=0.91, p<0.001) and between the CSDD-K and GDS15 (r=0.75, p<0.001). ROC curve analysis identified a cut-off score of 7 for the CSDD-K, where the sensitivity was 87.5% and the specificity was 100%. Factor analysis resulted in a four-factor solution accounting for 63.8% of the common variance. CONCLUSION: The CSDD-K showed good reliability and validity for the assessment of depressive symptom severity in AD patients. The CSDD-K is a useful instrument for assessing AD patients with depressive symptoms in Korean ethnic population.

OBJECTIVE:Optimized voxel based morphometry (VBM) has been increasingly applied to investigate differences in brain morphology between a group of Alzheimer's Disease (AD) patients and control subjects. Optimized VBM permits comparison of gray matter (GM) volume at voxel-level from the entire brain. The purpose of this study was to assess the regional GM volume loss measured by optimized VBM in AD compared to controls METHODS:Twenty-three AD patients and 20 cognitively normal elderly control subjects included in this study. To improve the VBM performance, the study specific template and the probability maps were generated from the control subjects. RESULTS:Optimized VBM analysis revealed GM loss, including hippocampus, amygdala, anterior cingulate, posterior cingulate, insula, frontal lobe and middle temporal complex in the AD group as compared to normal control group CONCLUSION:The VBM results confirmed previous findings of temporal lobe and limbic lobe atrophic changes in AD, and suggest that these abnormalities may be confined to specific sites within that lobe, rather than showing a widespread distribution.

In early thrombolytic therapy for acute focal ischemic stroke, the start of treatment within therapeutic time window is one of the most important thing. Recently, new imaging modalities such as SPECT, transcranial doppler, diffusion/ perfusion-weighted MRI, and MR anglography have been implicated to avoid time consumption and delayed therapy. Of these, MR angiography is nomnvasi and rapid technique to visualize large and medium-sized arteries. We explored the usefulness of MR angiography in early thrombolytic therapy. Arterial occlusion of three patients with severe ischemic stroke were demonstrated on MR anglography and wluch were treated with Urokmase (10, 000-20, 000 units/kg) by intravenous infusion within 2-4 hours after symptom onset. Recanalization and brain lesion was assessed by repeated MR angiography and MRI or CT 24 hours later. Clinical improvement was observed in two patients 5-24 hours after initiation of treatment. In one patient hemorrhagic infarction without clinical deterioration was detected by follow-up computed tomography. Recanalization was documented on repeated MR angiography of three patients. MR angiography can document occlusion of stroke-related vasculature without delay of thrombolytic therapy and repeated MR anglography can reveal whether recanalization has occurred.

PURPOSE: Several therapeutic approaches have been introduced and tried to treat Frey syndrome following parotidectomy. However they were not proved as an effective treatment. A new therapeutic modality using botulinum toxin injections was presented previously by several study groups. But, the duration of the demonstrated positive effect was essentially unknown so far. The purpose of this clinical investigation is to demonstrate the effectiveness of Botulinum toxin type A(BTXA) in patients with Frey syndrome. METHODS: For this study, 12 patients were treated, They were assessed with the Minor's iodine-starch test and interviewed before and after treatment. Botulinum toxin is injected with 1.0cm2 apart into the skin where symptoms of Frey's syndrome has manifestated. The patients were classified according to the concentration of botulinum toxin and dosage of botulinum toxin. RESULTS: The outcome measures were the time of reappearance of gustatory sweating(subjective study), and the results of an Minor's iodine-starch test(objective study) of 3 weeks, 3 months, 6 months, 9 months, 12 months after treatment. This treatment was effective in all groups of patients. The concentrations and the amount of dosages did not affect the treatment. But high concentration produced faster effectiveness in subjective. CONCLUSION: Botulinum toxin type A(BTXA) for Frey syndrome is easy, convenient and effective withouts severe complication. And the patients has no difficulty and limitation in their life.

BACKGROUND: Laparoscopic surgery in the Trendelenburg position affects the cardiopulmonary system and may also influence intraocular pressure (IOP). The purpose of this study was to compare the effects of propofol and sevoflurane anesthesias on IOP change during laparoscopic hysterectomy. METHODS: Thirty-one women were randomly allocated to either a propofol (P-group, n = 15) intravenous anesthesia group or a sevoflurane (S-group, n = 16) inhaled anesthesia group with fentanyl-N2O/O2-vecuronium. Heart rate, mean arterial pressure, plateau airway pressure, ETCO2, and IOP were measured before induction (T1), 10 min after induction (T2), 10 min after pneumoperitoneum in the Trendelenburg position (T3), and 5 min after pneumoperitoneum deflation in the horizontal position (T4). RESULTS: IOP was significantly decreased in both groups after induction. IOP was increased in both groups after pneumoperitoneum in the Trendelenburg position, but IOP in the sevoflurane group was significantly higher than that in the propofol group. CONCLUSIONS: Propofol intravenenous anesthesia may be a better choice for IOP control during laparoscopic surgery.
