BACKGROUND: In this study, we investigated the early time course of expression of the major histocompatibility (MHC) antigens, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin-6 and the histopathological changes in the coronary arteries of cardiac allografts exchanged between inbred mice strains that differ in one loci of class I major histocompatibility antigen (B10.BR to B10.A). MATERIAL AND METHOD: No immunosuppressive therapy was used. Both allografts and the hearts of the recipients were harvested at 7 (group 1, n=6), 15 (group 2, n=6), 21 (group 3, n=6), and 30 (group 4, n=6) days after transplantation. They were examined by immunohistochemistry, microscopy and morphometry. All allografts had contractions at the time of harvest. RESULT: A strong MHC class I antigen expression was present on the endothelial and medial cells of the coronary arteries in group 1 and remained unchanged in the rest of the groups. However, MHC class II reactivity was none or very little at any time. Mild to moderate ICAM-1 expression was observed on the endothelial cells, but not on the medial cells at any time by 30 days. VCAM-1 expression was strong both on the endothelial and medial cells at any time. Moderate degree expression of interleukin-6 was observed from 7 to 30 day specimens. Histopathologically, percentage of affected vessels (vessels with intimal thickening) was less than 10 % in 7 day group and increased up to 50 % at 30 days. Mean percent narrowing of the lumen of the affected vessels revealed less than 20 % at 7 days and 40 % at 30 days. The area occupied by tropomyosin positive cells in the intimal lesion, graded from 0 to 3, showed gradual increase but remained between grade 0 to 1 by 30 days. Medial integrity was also well preserved at any time. Moderate perivascular mononuclear cell infiltration was observed at 7 days and it was progressively increased upto 30 days. Recipients' heart revealed no positive immunopathologic findings. CONCLUSION: In this study, the early time course of progression of the transplantation vasculopathy was demonstrated in the murine heterotopic heart transplant model.

The safety and efficacy of the CO2laser as a replacement for the steel scalpel is well documented in plastic surgery, but the use of the laser blepharoplasty has been controversy. This study compares and contrasts the use of the CO2 laser with conventional method in cosmetic upper eyelid blepharoplasty. Thirteen Patients underwent blepharoplasty in a paired comparison study. Four patients(Group A) underwent blepharoplasty by laser, another four patients (Group B) underwent blepharoplasty by conventional method, and the other five patients(Group C) underwent upper eyelid blepharoplasty using the laser on one eye and a conventional method on the other side. Preoperative factor(set up time, equipment), intraoperative factor(actual operation time, bleeding, visibility), postoperative factor(swelling, ecchymosis, immediate & short term result) were evaluated. The advantage of using the CO2 laser rather than the steel scalpel in blepharoplasty are less bleeding and superior intraoperative visibility. The disadvantage of using the laser compared with steel scalpel include the cost of purchasing and maintaining the laser equipment, the need for additional and extensive laser training for surgeons and assistants, and the need for two assistants rather than the one needed for scalpel surgery There were no complications with either the scalpel or the laser.

For many years the standard surgical treatment for carpal tunnel syndrome has been division of the transverse carpal ligament under direct vision through a palm incision. Although the effectiveness and Patient acceptability of the conventional open carpal tunnel release are good, disability from a painful palm cutaneous neuroma, and prolonged swelling are reported Endoscopic carpal tunnel release seems to result in less postoperative morbidity, and minimal serious complications. Because endoscopic carpal tunnel release leaves the overlying skin, the subcutaneous fat and the palmer fascia and its attachments to the thenar and hypothenar musculature intact its proponents maintain that their patient have less scar tenderness, quicker recovery of grip strength, and earlier to return activities of daily living and work The endoscopic approach(Agee single portal technique), which includes specific localization of the hook of hamate, flexor retinaculum and the superficial palmar arch utilizing topographical landmarks, avoids entry into Guyon's canal and common digital nerves. We experienced four cases of carpal tunnel syndrome. In four cases, patients with carpal tunnel syndrome have been performed endoscopic carpal tunnel release with minor complication.

BACKGROUND/AIMS: Our aim was to assess whether short-term treatment with soluble tumor necrosis factor (TNF) receptor affects circulating markers of bone metabolism in rheumatoid arthritis (RA) patients. METHODS: Thirty-three active RA patients, treated with oral disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids for > 6 months, were administered etanercept for 12 weeks. Serum levels of bone metabolism markers were compared among patients treated with DMARDs at baseline and after etanercept treatment, normal controls and naive RA patients not previously treated with DMARDs (both age- and gender-matched). RESULTS: Bone-specific alkaline phosphatase (BSALP) and serum c-telopeptide (CTX)-1 levels were lower in RA patients treated with DMARDs than in DMARD-naive RA patients. After 12 weeks of etanercept treatment, serum CTX-1 and sclerostin levels increased. In patients whose DAS28 improved, the sclerostin level increased from 1.67 +/- 2.12 pg/mL at baseline to 2.51 +/- 3.03 pg/mL, which was statistically significant (p = 0.021). Increases in sclerostin levels after etanercept treatment were positively correlated with those of serum CTX-1 (r = 0.775), as were those of BSALP (r = 0.755). CONCLUSIONS: RA patients treated with DMARDs showed depressed bone metabolism compared to naive RA patients. Increases in serum CTX-1 and sclerostin levels after short-term etanercept treatment suggest reconstitution of bone metabolism homeostasis.

The object of this study was to evaluate the effect of uric acid lowering therapy in reducing the new development of comorbidities and the frequency of acute attacks in gout patients. We retrospectively reviewed patients who were diagnosed to have gout with at least 3 yr of follow up. They were divided into 2 groups; 53 patients with mean serum uric acid level (sUA)<6 mg/dL and 147 patients with mean sUA> or =6 mg/dL. Comorbidities of gout such as hypertension (HTN), type II diabetes mellitus (DM), chronic kidney disease, cardiovascular disease (CVD) and urolithiasis were compared in each group at baseline and at last follow-up visit. Frequency of acute gout attacks were also compared between the groups. During the mean follow up period of 7.6 yr, the yearly rate of acute attack and the new development of HTN, DM, CVD and urolithiasis was lower in the adequately treated group compared to the inadequately treated group. Tight control of uric acid decreases the incidence of acute gout attacks and comorbidities of gout such as HTN, DM, CVD and urolithiasis.

BACKGROUND AND OBJECTIVES: Mechanical circulatory support with extracorporeal membrane oxygenation (ECMO) and ventricular assist device has always been the optimal choice for treating the majority of medically intractable low cardiac output case. We retrospectively investigated our institution's outcomes and variables associated with a high risk of mortality. SUBJECTS AND METHODS: From 1999 to 2014, 86 patients who were of pediatric age or had grown-up congenital heart disease underwent mechanical circulatory support for medically intractable low cardiac output in our pediatric intensive care unit. Of these, 9 grown-up congenital heart disease patients were over 18 years of age, and the median age of the subject group was 5.82 years (range: 1 day to 41.6 years). A review of all demographic, clinical, and surgical data and survival analysis were performed. RESULTS: A total of 45 (52.3%) patients were successfully weaned from the mechanical assist device, and 25 (29.1%) survivors were able to be discharged. There was no significant difference in results between patients over 18 years and under 18 years of age. Risk factors for mortality were younger age (<30 days), functional single ventricle anatomy, support after cardiac operations, longer support duration, and deteriorated pre-ECMO status (severe metabolic acidosis and increased levels of lactate, creatinine, bilirubin, or liver enzyme). The survival rate has improved since 2010 (from 25% before 2010 to 35% after 2010), when we introduced an upgraded oxygenator, activated heart transplantation, and also began to apply ECMO before the end-stage of cardiac dysfunction, even though we could not reveal significant correlations between survival rate and changed strategies associated with ECMO. CONCLUSION: Mechanical circulatory support has played a critical role and has had a dramatic effect on survival in patients with medically intractable heart failure, particularly in recent years. Meticulous monitoring of acid-base status, laboratory findings, and early and liberal applications are recommended to improve outcomes without critical complication rates, particularly in neonates with single ventricle physiology.

The aim of this study was to determine whether skin temperature measurement by digital thermography on hands and feet is useful for diagnosis of Raynaud's phenomenon (RP). Fifty-seven patients with RP (primary RP, n = 33; secondary RP, n = 24) and 146 healthy volunteers were recruited. After acclimation to room temperature for 30 min, thermal imaging of palmar aspect of hands and dorsal aspect of feet were taken. Temperature differences between palm (center) and the coolest finger and temperature differences between foot dorsum (center) and first toe significantly differed between patients and controls. The area under curve analysis showed that temperature difference of the coolest finger (cutoff value: 2.2degrees C) differentiated RP patients from controls (sensitivity/specificity: 67/60%, respectively). Temperature differences of first toe (cutoff value: 3.11degrees C) also discriminated RP patients (sensitivity/specificity: about 73/66%, respectively). A combination of thermographic assessment of the coolest finger and first toe was highly effective in men (sensitivity/specificity : about 88/60%, respectively) while thermographic assessment of first toe was solely sufficient for women (sensitivity/specificity: about 74/68%, respectively). Thermographic assessment of the coolest finger and first toe is useful for diagnosing RP. In women, thermography of first toe is highly recommended.

PURPOSE: We determined the usefulness of in vitro germ cell culture in nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome, no sperm in testicular sperm extraction. MATERIALS AND METHODS: This study included 44 patients (45 testicular tissues) with nonobstructive azoospermia who were diagnosed with Sertoli cell only syndrome and were found to have no sperm in testicular sperm extraction between January 2006 and July 2008. Among the 45 testicular tissues, 22 tissues were processed for culture. In the in vitro cultures, the testicular tissues were dissociated and plated on gelatin-coated dishes. Patients were divided into 2 groups according to culture success: group I, culture positive (+; n=10); and group II, culture negative (-; n=12). RESULTS: The mean patient ages were 31.73 and 31.68 years for groups I and II, respectively. The mean testicular sizes were 10.19 and 10.42 cc, respectively; the semen volumes were 2.86 and 3.04 cc, respectively; and the mean FSH, LH, and testosterone levels were 18.86 mIU/ml, 5.99 mIU/ml, and 4.46 ng/ml vs. 21.02 mIU/ml, 6.29 mIU/ml, and 4.32 ng/ml for groups I and II, respectively, with no significant differences between the groups (p>0.05). The culture rate of nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome was 45.5% (10/22). Round spermatid injection was done in 2 patients with consent of the patients, but implantation failed. Among the 45 tissues, germ cells were found in 8 tissues after pathologic reexamination. CONCLUSIONS: The in vitro culture of germ cells would be useful in the advanced treatment of nonobstructive azoospermic patients.

OBJECTIVE: This study examines the effects of tumor necrosis factor (TNF) blockade on markers of bone metabolism in peripheral blood from active rheumatoid arthritis (RA) patients. METHODS: Eighteen patients (16 women, 2 men) aged 50 years (range 37-63 years), with persistently active RA (mean disease duration 7 years) were studied. Most took methotrexate (mean dose 12.5 mg) and all except one received corticosteroid (mean dose 5.7 mg). Four were treated with etanercept, eight received adalimumab and six received infliximab. Before and six months after taking TNF blockers, blood was sampled to obtain peripheral blood mononuclear cells (PBMCs), and serum bone turnover markers and acute phase reactants were measured. PBMCs were seeded and cultured to produce osteoblastic lineage cells and osteoclasts. RESULTS: The formation of calcified nodules by osteoblastic lineage cells from PBMC increased from 205.7±196.3 µmol/well at the baseline to 752.5±671.9 µmol/well after TNF blockade (p<0.024). The serum levels of bone formation markers, including bone specific alkaline phosphatase and osteocalcin also increased. The number of circulating osteoclasts and area of bone resorption pits made by osteoclasts were reduced after TNF blockade. CONCLUSION: The activity of circulating osteoblastic lineage cells increased after TNF blockade, whereas peripheral osteoclastogenesis tended to be suppressed. This is the first study of cultured human peripheral osteoblastic lineage cells in RA patients. Given that peripheral bone formation is difficult to study using radiologic methods, culture of these cells may provide a new modality for studying bone metabolism in RA.
