OBJECTIVE: The purpose of this study was to evaluate the reliability of patient pain drawings using a 3-dimensional (3D) virtual human body system. METHOD: Pain drawings were collected from thirty-four patients with various types of musculoskeletal pain. On the first clinic visit, patients were instructed to draw in their pain areas on a diagram depicting the body (P1). The examining physiatrist, blinded to the patients drawing, also drew in the pain areas on a separate diagram based on thorough history taking (D). After 2 to 9 days without treatment, patients repeated their pain drawings (P2). A second physiatrist input each of the pain drawings into thePain Chart System (PCS), for comparison of pain distribution sites and areas among the three drawings. The weighted-sum of comparison algorithms was calculated for similarity determinations between drawings. RESULTS: The similarity values between P1 and P2, and P1 and D were 0.63+/-0.18 (mean+/-S.D.) and 0.62+/-0.18 (mean+/-S.D.), respectively, reflecting a high reliability of pain drawings. CONCLUSION: High test-retest and inter-individual reliability of successive pain drawings suggest that pain drawings may be a useful tool to describe the painful sites.

Ventriculitis is one of the most serious complication of the ventriculoperitoneal shunt, which may cause intelligence deterioration in children. The purpose of this study is to investigate the mechanism of the neural damage in lipopolysacciride(LPS)-induced ventriculitis in rat. Ventriculitis was induced by intraventricular injection of 1mg/Kg LPS in rat. H & E and Tunel stains were done on the day 1, 2 and 14 to access the microscopic changes of the periventricular tissue and apoptosis, respectively. TNF-alpha and IL-1beta mRNA expressions were studied using RT-PCR. HRP was injected into the femoral vein and electron microscopic examinations were performed to access the BBB changes. Light microscopic examination one day after LPS injection revealed neutrophilic infiltration, which diminished on day 4, and disappeared on 14. Tunel stain revealed apoptosis on day 1 and 4. TNF-alpha and IL-1beta were expressed on day 1, and diminished progressively thereafter. HRP histochemical electron microscopic examination revealed accumulation of HRP reaction in the interstitial space around the brain parenchyma. These findings suggest the opening of the BBB and increased capillary permeability in the periventricular tissue in the LPS induced ventriculitis. This can possibly damage the periventricular neural tissue. TNF-alpha and IL-1beta seemed to play an important role in the opening of the BBB.

Carcinoid tumors of the intestinal tract are uncommon neoplasms thought to arise from argentaffin cells in the base of the intestinal crypts. Carcinoid tumors of other sites have since been reported with increasing frequency. We experienced one case of rectal carcinoid tumor and the other case of stomach carcinoid turnor. A 52-year-old male patient was admitted to the hospital because of right upper abdominal discomfort. On the CT scan, multiple low density masses were noticed. Sigmoidoscopy revealed the whitish yellow ulcerofungating mass which had vague margin. And a 31-year-old male patient was admitted to the haspital because of hematemesis. On the gastrofiberscopic examination, an ovoid shallow ulcer crater which had elevated margin, smooth tapered fold and vissible vessel was noticed on the anterior wall side of the high body. The biopsy specimen in both these cases showed carcinoid cells. 24h urine 5-HIAA of these cases was negative. Awareness of carcinoid tumor in differential diagnosis of hepatic metastasis and of gastric ulcer is necessary.

PURPOSE: The purpose of this study is to analyze the most discriminative MR findings for making the differential diagnosis of tuberculous and pyogenic spondylitis. MATERIALS AND METHODS: Sixty MR scans of 18 pyogenic spondylitis patients and 42 tuberculous spondylitis patients were retrospectively reviewed. The statistical analysis was performed using stepwise discriminant analysis and Student's T-test. RESULTS: The patients with tuberculous spondylitis had a significantly higher incidence of MRI findings as follows (p <0.05): smooth margin of a paraspinal mass/abscess in 67% [28/42] of the tuberculous spondylitis patients vs 6% [1/18] in the pyogenic spondylitis patients, mild endplate erosion in 52% [22/42] vs 38% [7/18], respectively, the presence of paraspinal mass/abscess in 100% [42/42] vs 6% [1/18], respectively, central dark signal intensity of the abscess in 86% [36/42] vs 39% [7/18]), respectively, subligamentous spread in 81% [34/42] vs 50% [9/18]), respectively, severe vertebral collapse in 20% [8/42] vs 11% [2/18]), respectively, and posterior extension in 62% [26/42] vs 33% [6/18]), respectively. Among of them, the significant discriminative MR findings were the margin of a paraspinal mass, the grade of endplate erosion and the presence or absence of a paraspinal mass in that order. CONCLUSION: In the differentiation of tuberculous and pyogenic spondylitis, the margin of the paraspinal mass, the grade of endplate erosion and the presence or absence of a paraspinal mass are the most three discriminating MR findings in that order.

BACKGROUND: Eisenmenger syndrome is a complication of heart dease with left-to-right shunt in which the pulmonary arterial pressure is increased due to increased pulmonary vascular resistance and the shunt directions becomes bidirectional or reversed at the level of atria, ventricies, or great arteries. Corrective surgery is impossible unless there is substantial reactive change pulmonary vascular resistance. METHOD: To identify clinical and hemodynamic features and observe natural history of adult patients with Eisenmenger syndrome, a retrospective clinical study was done on 61 patients(male:female=39:22) with Eisenmenger syndrome who were admitted to Seoul National University Hospital from September, 1979 to A piril, 1989, and were confirmed after cardiac catheterization and angiography. RESULTS: VSD was most freguent underlying defect(31 cases, 51%), followed by PDA(12 cases, 20%), ASD(9 cases,15%) and Combined lesion(9 cases, 15%). The average age was 27.3 years with the peak incidence in third decades. Effort intolerance(96.7%), palpitation(75.4%), hemoptysis(19.7%), and syncope(8.2%) were common symptoms, and cyanosis(62.3%), clubbing(63.9%) and increased heart sound were freguently(86.9%) observed. The mean pressure of the pulmonary artery and the total pulmonary vascular resistance were markedly elevated with the mean value of 76.7+/-14.2mmgHg and 29.3+/-12.HU respectively, 4 of the 19 patients who were given 100% oxygen inhalation showed reversibility of the pulmonary vascular resistance. During follow up(mean:40+/-29 months), Complications include infective endocarditis(1 case), brain abcess(2 case), atrial fibrillation(3 case), acute renal failure(1 case) and gout(2 case). 6 patients(10%) died during medical follow-up period(mean:40+/-29 months). Congestive heart failure and pulmonary infarction after cardiac catheterization including one postoprative death were causes of death. CONCLUSION: VSD, ASD, and PDA were common underlying defects of adult Eisenmenger syndrome. Complication was not uncommon and the common cause of death was congestive failure. The prognosis of the patients with Eisenmenger syndrome may not be so dismal as has been thought, though the exact survival to be determined.

Mini implants had been used provisionally for the healing period of implants in the beginning. But it becomes used for the on-going purpose, because it is simple to use, economic and especially suitable for the overdenture. But there is few studies about the stability of mini implants, that is most important factor for the on-going purpose, and particularly the implant parameters affecting the initial stability. The purpose of this study was to evaluate the stress and the strain distribution pattern of immediate- loaded screw type orthodontic mini-implant and the parameters affecting the initial stability of immediate-loaded mini-implant. Two dimensional finite element models were made and contact non-linear finite element analysis was performed. The magnitude and distribution of Von Mises stresses were evaluated. The obtained results were as follows: 1. The stress was concentrated on the thread tip of an implant in the cortical bone. 2. The direction of load is the most important factor for the stress distribution in cortical bone. 3. The diameter of an implant is the most important factor for the stress distribution in the trabecular bone. In conclusion, if the horizontal load vector is successfully controlled, mini-implants, which diameter is under 3mm, can be used for the on-going purpose.

BACKGROUND AND OBJECTIVES: This study compared two types of skin graft reconstruction for the defect of the radial forearm free flap. SUBJECTS AND METHOD: Ten cases of split-thickness skin graft (STSG) harvested from the thigh were analyzed. Also, ten cases of full-thickness skin graft (FTSG) harvest from the inguinal area applied with vacuum-assisted closure (VAC) system were analyzed. RESULTS: The defect size of the radial forearm was increased more in the STSG group than in the FTSG group (p<0.05). Skin grafts were recovered completely sooner in the FTSG group than in the STSG group although it was not statistically significant (p=0.082). Five complications (pruritus, hypertrophic scar) were found in the donor site in the STSG group (p<0.05). FTSG gave better scores according to the Vancouver Scar Scale in terms of pigmentation, pliability, and height (p<0.05). CONCLUSION FTSG harvested from the inguinal area with the application of VAC system has many advantages for the defect of the radial forearm free flap although it is usually used for smaller size defects than for STSGs.
