A 1-year-old Korean domestic short-haired cat presented with skin hyperextensibility and a severely macerated wound on the skin of the dorsal part of the neck. Diagnostic studies including histopathology and skin extensibility index revealed congenital cutaneous asthenia (Ehlers-Danlos syndrome). In this cat, the skin wounds and defects were successfully managed with standard wound management and cosmetic surgery. Although skin hyperextensibility is persistent, the cat has lived well without other complications to date. To the best of our knowledge, this is the first report of cutaneous asthenia in a cat in Korea.

OBJECTIVES: Rapidly progres s ive glomerulonephritis (RPGN) is a clinico- pathologic entity characterized by extens ive crescent formation(usually involving 50% or more of glomeruli) as the principal his tologic finding and a rapid deterioration of kidney function, which can lead to end s tage renal disease within a few weeks. T he etiology and incidence of RPGN has been well defined in Europe and North America, however, there has been no report of a large series in Korea. T he aim of the present s tudy was to analyze the etiology and clinico- pathologic features of 26 patients with RPGN, seen during 1983-1997. METHODS: T wenty-six patients with RPGN(crescents in > 50% of glomeruli) were obs erved during a period of las t 14 years. Male to female ratio was 1:1.4, and the mean age was 30(6-75) years. Mean time from the initial symptoms to the ESRD was 3.1 months . RESULTS: The incidence of RPGN in our series was 2.1% of primary glomerulonephritis. Immunecomplex mediated disease was presented in 14 cases (54%), including 6 sys temic lupus erythematos us, 3 post- streptococcal glomerulonephritis, 3 Henoch- Schonlein purpura, and 2 IgA nephropathy. Pauci- immune disease was presented in 12 cases (46%), including 3 Wegener' s granulomatos is, one necrotizing crescentic glomerulonephritis, and 8 idiopathic crescentic glomerulonephritis. However, there was none of anti-GBM- mediated disease in our s tudy. ANCA were found in 6 patients. All 3 patients with WG were C- ANCA pos itive, whereas one patient with PSGN, necrotizing cres centic GN, and idiopathic crescentic GN were P- ANCA pos itive, respectively. Initial clinical and laboratory features included edema(80%), hypertens ion(72%), oliguria(68%), a decreased renal function(serum creatinine > 5mg/dL, 35%), and gros s hematuria(36%). Renal biopsy showed large crescents more than 80% of the glomeruli in 14 cases (54%) which were predominantly fibrocellular. Fifteen patients (58%) were treated with prednis olone alone, and 12 of them received puls e doses of corticosteroids. Five patients were treated with prednisolone and cyclophos phamide IV pulse. Two cases received plasma exchange. During the mean follow-up of 31+/-37 months, 18 patients (69%) developed inexorable progression of renal failure, three(12%) showed recovery of renal function, and two(8%) showed partial improvement, which is followed by varying degrees of renal insufficiency. During follow-up, three patients died : two from res piratory failure with severe pulmonary hemorrhage and one from opportunistic pulmonary infection during immunosuppressive therapy. Poor prognos is is as sociated with hypertension, increased serum creatinine level at the time of diagnosis, large crescents more than 85% of glomeruli, and glomerular scleros is . CONCLUSION: We conclude that an earlier diagnos is including kidney biopsy and the more aggressive treatment are essential in the management of RPGN.

Traditionally, preeclamptic women who meet established criteria for severe disease aredelivered expeditiously. Although delivery is always appropriate thrapy for the mother, itmay not be for the fetus remote from term. The purpose of this investigation was to evaluatethe differences of pregnancy and neonatal outcome of severe preeclampsia and normalpregnancy, especially before 34 weeks gestational age, and to determine whether aggressiveor expectant management of severe preeclampsia before 34 weeks is more beneficial tomaternal and fetal outcome. A hundred and twenty consecutive pregnancies complicated bysevere preeclampsia and a hundred and twenty normal pregnancies were stuided.The results were as follows:1. The incidence of severe preeclampsia was 3.9%(130 of 3328). The 26~30 year oldage group was most common, 43%(52 patients).2. In case of study between severe preeclamptic patients and normal pregnant patient,there was no differences regarding gestational age at delivery, birth weight, cesarean sectionrate, incidence of RDS, perinatal death. The 1min/5 min Apgar scores of severe preeclampsiais significantly lower than control group(6/7 vs 7/8, p < 0.05). Neonates with SGA(small for gestational age) were found in 29% neonates of patients with severe preeclampsia,which is significantly higher than normal pregnancy group(6%, p < 0.05).3. There was no significant difference between expectant(n=10) and aggressive(n=21)management group less than 34 weeks gestation regarding the gestational age of admissionand delivery, blood pressure, proteinuria, serum creatinine, hemoglobin, hematocrit, pletelets,liver enzymes, and LDH. Only the prolongation of gestational age in the expectant managementgroup is significantly higher than in the aggressive management group(7 vs 2 days,p < 0.05).4. The neonatal and pregnancy outcome of expectant(n=10) and aggressive managementgroup(n=15) were as follow: The birth weight in the expectant management groupis lower than in the aggressive management group(1316.7+/-668.8g vs 1576.2+/-428.7 g, p < 0. 05). The incidence of SGA in the expectant management group is higher than in theaggressive management gorup(50% vs 27%, p=not significant). There was no significant differencebetween expectant and aggressive management group regarding the 1 min/ 5 minApgar score, the cesarean section rate, and the frequency of respiratory distress syndrome,cerebral hemorrhage, renal failure, sepsis, DIC of neonates.

PURPOSE: To compare the therapeutic effects on upper extremity paresthesia of intra-muscular steroid injections into the scalene muscle with those of stretching exercise only. MATERIALS AND METHODS: Twenty patients with upper extremity paresthesia who met the criteria were recruited to participate in this single-blind, crossover study. Fourteen of 20 patients were female. The average age was 45.0+/-10.5 years and duration of symptom was 12.2+/-8.7 months. Each participant completed one injection and daily exercise program for 2 weeks. After randomization, half of all patients received ultrasound-guided injection of scalene muscles before exercise, while the other was invested for the other patients. RESULTS: After two weeks, there was a significant decrease of the visual analog scale score of treatment effect compared with baseline in both groups (6.90 to 2.85 after injection and 5.65 to 4.05 after stretching exercise, p<0.01). However, injection resulted in greater improvements than stretching exercise (p<0.01). The number of patients with successful treatment, defined as >50% reduction in post-treatment visual analog scale, was 18 of 20 (90.0%) after injection, compared to 5 of 20 (25.0%) after stretching exercise. There were no cases of unintended brachial plexus block after injection. CONCLUSION: Ultrasound-guided steroid injection or stretching exercise of scalene muscles led to reduced upper extremity paresthesia in patients who present with localized tenderness in the scalene muscle without electrodiagnostic test abnormalities, although injection treatment resulted in more improvements. The results suggest that symptoms relief might result from injection into the muscle alone not related to blockade of the brachial plexus.

Facial scar is one of the most common problems in plastic surgery department. Many various methods are attempted to improve facial scars, but there is no definite satisfactory method on scar revision. Authors have been interested in a tendency to show good results when traumatic lacerations were accompanied by abrasions. The improved appearance of the scars with this situation is the result that there were fewer elevations and depressions, and no break in continuity of the epidermal covering on both sides of the scar. But mechanical or other dermabrasive methods have a risk of hyperpigmentation. Authors suggest the scar revision with frostbite using dry ice. This method has little hyperpigmentation due to the sensitivity of melanocytes to cold injury. And the tissue destruction is progressed selectively because of the resistance of collagen against the cold injury and the preserved dermal fibrous network as the structural framework. These characteristics of cryotherapy improve the result of scar revision with fewer side effects rather than other dermabrasive methods. We performed this method to 349 patients from 1993 to 2003 and obtained high patients' satisfaction (85.9% more than fair). Moreover, this method is simple, cheap and handy. In conclusion, the scar revision with frostbite using dry ice is very useful method to improve facial scars.

STUDY DESIGN: Prospective controlled study. PURPOSE: The results of conventional open surgery was compared with those from minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for lumbar fusion to determine which approach resulted in less postoperative paraspinal muscle degeneration. OVERVIEW OF LITERATURE: MI TLIF is new surgical technique that appears to minimize iatrogenic injury. However, there aren't any reports yet that have quantitatively analyzed and proved whether there's difference in back muscle injury and degeneration between the minimally invasive surgery and conventional open surgery in more than 1 year follow-up after surgery. METHODS: This study examined a consecutive series of 48 patients who underwent lumbar fusion in our hospital during the period, March 2006 to March 2008, with a 1-year follow-up evaluation using MRI. There were 17 cases of conventional open surgery and 31 cases of MI-TLIF (31 cases of single segment fusion and 17 cases of multi-segment fusion). The digital images of the paravertebral back muscles were analyzed and compared using the T2-weighted axial images. The point of interest was the paraspinal muscle of the intervertebral disc level from L1 to L5. Picture archiving and communication system viewing software was used for quantitative analysis of the change in fat infiltration percentage and the change in cross-sectional area of the paraspinal muscle, before and after surgery. RESULTS: A comparison of the traditional posterior fusion method with MI-TLIF revealed single segment fusion to result in an average increase in fat infiltration in the paraspinal muscle of 4.30% and 1.37% and a decrease in cross-sectional area of 0.10 and 0.07 before and after surgery, respectively. Multi-segment fusion showed an average 7.90% and 2.79% increase in fat infiltration and a 0.16 and 0.10 decrease in cross-sectional area, respectively. Both single and multi segment fusion showed less change in the fat infiltration percentage and cross-sectional area, particularly in multi segment fusion. There was no significant difference between the two groups in terms of the radiologic results. CONCLUSIONS: A comparison of conventional open surgery with MI-TLIF upon degeneration of the paraspinal muscle with a 1 year follow-up evaluation revealed that both single and multi segment fusion showed less change in fat infiltration percentage and cross-sectional area in the MI-TLIF but there was no significant difference between the two groups. This suggests that as time passes after surgery, there is no significant difference in the level of degeneration of the paraspinal muscle between surgical techniques.

BACKGROUND: AML with myelodysplasia related changes (AML MRC) is known to show a poor prognosis compared with de novo AML, but controversies exist about the prognostic impact of multilineage dysplasia (MLD) among MRC. We investigated the prognostic impact of MLD in AML MRC. METHODS: A total of 357 patients newly diagnosed as AML at Asan Medical Center from January 2001 to December 2005 were analyzed. They were diagnosed and classified as AML with recurrent genetic abnormalities, AML MRC, and AML not otherwise specified (AML NOS). Prognostic markers including overall survival (OS) and event free survival (EFS) were obtained through retrospective analysis of electronic medical records. RESULTS: AML MRC patients showed a lower complete remission (CR) rate (44.7% vs. 64.9%, P=0.002) and shorter OS (297 vs. 561 days, P=0.004) and EFS (229 vs. 374 days, P=0.004) than AML NOS patients. Patients with MLD among AML MRC also showed a lower CR rate (37.7%, P=0.001) and shorter OS (351 days, P=0.036) and EFS (242 days, P=0.076) than AML NOS patients. However, among AML MRC patients, there were no differences in OS, EFS and CR between patients with and without MLD. CONCLUSIONS: AML MRC patients showed a lower CR rate and shorter OS and EFS than AML NOS patients. AML MRC patients with MLD showed similar results and their prognosis was not different from those without MLD. MLD findings among AML MRC could be an independent poor prognostic factor in de novo AML.

Paraffinoma induces many unexpected complications such as tissue necrosis, granuloma formation, hypersensitivity, embolism and even carcinoma. The treatment modality is known to be primary repair, flap surgery, skin graft, radiotherapy and high frequency current treatment after the excision of the lesion. Although these methods can remove the paraffinoma and resurface penile shaft, various complications such as skin tension after surgery, hypertrophic scars, difficulty of erection, and deficiency of bulkiness are frequently occurred. Groin flap is the proper method for the patients who want simultaneously soft tissue reconstruction and augmentation of penis. A 32 year-old male patient who visited our clinic had firm mass, abscess, skin necrosis, and dyspareunia after the injection of paraffin into penis 3 months ago. Reconstruction was executed using right side of the groin flap after the radical resection of the whole tissues ruined by infections and infiltration of paraffin. The penile bulkiness, erectile function and duration of erection was all satisfactory. The follow-up period was 7 months after the surgery and no specific complication was developed. Groin flap is the satisfactory method to enhance penile bulkiness as well as resurface the lesion.

Journal of the Korean Fracture Society 2006;19(4):443-448
PURPOSE: To evaluate the results of the treatment of intercondylar fractures of the humerus using Y-plate. MATERIALS AND METHODS: The subjects were 17 patients with intercondylar fracture of humerus who were treated using the Y-plate. Nine cases were C1 type, 4 were C2 type, and the remaining 4 were C3 type. 11 subjects had accompanying fractures of another part of the body. The average age was 48.8. The average follow up period was 33 months. We used Mayo Elbow Performance Score and Risborough-Radin's rating score for each patient as the methods of rating. RESULTS: The average range of motion of the elbow was 105 degrees (50~150 degrees). According to Cassebaum's classification for elbow range of motion, 7 cases were rated very good, 1 cases were good, 4 cases were fair, and 1 cases were poor. According to Mayo Elbow Performance Score, 7 were excellent, 7 were good, 2 fair, and 1 poor. Of the 3 patients who were fair or poor in Mayo Elbow Performance Score, 2 were type C3 fractures, and all 3 had major accompanying fractures. No significant postoperative complications developed in all cases. CONCLUSION: The fixation with Y-plate can still be a relatively good modality of treatment for interconylar fractures of the humerus in selected cases, in spite of the known mechanical weakness of the Y-plate. The patients with severe intra-articular comminution showed relatively poor results. And we think that the age of the patient and the energy of the injury have more or less influence on the results of treatment.

Journal of the Korean Pediatric Society 2000;43(4):543-549
PURPOSE: We evaluated the change in the findings of DMSA scan after acute pyelonephritis (APN), and the relationship between renal scar formation and risk factors such as vesicoureteral reflux (VUR), organism and inflammatory reaction. METHODS: We examined 200 patients under the age of 5 years with first APN. DMSA scan, voiding cystourethrography (VCUG), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were performed initially. If the initial DMSA scan was abnormal, it was repeated after 6 months. RESULTS: Median age was 1.1 years. Initial renal defects existed in 136 (68%) of 200 cases. At 6 months after initial infection, follow up DMSA scan was checked in 61 children with initial renal defects for evaluation of scar. Initial renal defects disappeared in 19 (31%)children. Initial renal defects were present in 60 (64%) of 94 kidneys with the VUR, however, they were present in 94 (31.0%) of 306 kidneys without VUR(P<0.05). Among 72 kidneys with initial renal defects, scar developed in 27 (75%) of 36 kidneys with VUR and 22 (61%) of 36 kidneys without VUR (P>0.05). CRP was 11.0+/-7.0mg/dL in 127 patients with initial renal defects and 4.4 5.5mg/dL in 53 patients without initial renal defects (P<0.05) and CRP was 13.0+/-4.7mg/dL in 39 patients with scar and 8.7+/-4.6 mg/dL in 19 patients without scar in follow up DMSA scan (P<0.05). CONCLUSION: The presence of VUR and higher CRP level are risk factors for initial renal defects but renal scarring occured higher in the higher level of CRP, irrespective of VUR.
