Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

BACKGROUND: We aimed to evaluate the incidence, predictive factors, and impact of acute kidney injury (AKI) after thoracic endovascular aortic repair (TEVAR). METHODS: A total of 53 patients who underwent 57 TEVAR operations between 2008 and 2015 were reviewed for the incidence of AKI as defined by the RIFLE (risk, injury, failure, loss, and end-stage kidney disease risk) consensus criteria. The estimated glomerular filtration rate was determined in the perioperative period. Comorbidities and postoperative outcomes were retrospectively reviewed. RESULTS: Underlying aortic pathologies included 21 degenerative aortic aneurysms, 20 blunt traumatic aortic injuries, six type B aortic dissections, five type B intramural hematomas, three endoleaks and two miscellaneous diseases. The mean age of the patients was 61.2+/-17.5 years (range, 15 to 85 years). AKI was identified in 13 (22.8%) of 57 patients. There was an association of preoperative stroke and postoperative paraparesis and paraplegia with AKI. The average intensive care unit (ICU) stay in patients with AKI was significantly longer than in patients without AKI (5.3 vs. 12.7 days, p=0.017). The 30-day mortality rate in patients with AKI was significantly higher than patients without AKI (23.1% vs. 4.5%, p=0.038); however, AKI did not impact long-term survival. CONCLUSION: Preoperative stroke and postoperative paraparesis and paraplegia were identified as predictors for AKI. Patients with AKI experienced longer average ICU stays and greater 30-day mortality than those without AKI. Perioperative identification of high-risk patients, as well as nephroprotective strategies to reduce the incidence of AKI, should be considered as important aspects of a successful TEVAR procedure.

We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminution and varus malalignment. We herein describe technical aspects of trochanteric intramedullary nailing for femoral shaft fractures to improve its application and prevent implant-derived complications.

PURPOSE: To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. MATERIALS AND METHODS: Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using 192Ir between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment and in five patients as salvage treatment for recurrence after the initial surgery. In 12 patients, external beam radiotherapy (50-55 Gy/25 fractions) was combined with IBT of 21 Gy/7 fractions. In addition, IBT was administered as the sole treatment in three patients with a total dose of 50 Gy/10 fractions and as postoperative adjuvant treatment in one patient with a total of 35 Gy/7 fractions. RESULTS: The 5-year overall survival of the entire group was 70%. The actuarial local control rate after 3 years was 84%. All five recurrent cases after initial surgery were successfully salvaged using IBT +/- external beam radiotherapy. Two patients developed local recurrence at 3 and 5 months, respectively, after IBT. The acute complications were acceptable (< or =grade 2). Three patients developed major late complications, such as radio-osteonecrosis, in which one patient was treated by conservative therapy and two required surgical intervention. CONCLUSION: HDR IBT for oral cavity cancer was effective and acceptable in diverse clinical settings, such as in the cases of primary or salvage treatment.

BACKGROUND: This study was conducted to evaluate vinly chloride exposure in vinyl chloride and poly vinyl chloride manufacturing factories. The object of this study was compare two different type of air sampling method that of, NIOSH and OSHA recommended and Investigate quantitative correlation between level of vinyl chloride exposure and urinary thiodiglycolic acid excretion. METHODS: Air sampling was conducted by two method and sampling mediums were located at workers breathing zone in the same location. Sampling mediums were changed in 60 minute interval and sampling pumps were recalibrated at the same time. Urine was collected before and end of shift were stored frozen and determined by GC/FID analysis. RESULTS: In NIOSH method, time weighted average was 3.562 +/- 2.898 ppm and OSHA method time weighted average was 4.051 +/- 3.700 ppm. Concentration of urinary TdGA in before shift was 0.527 +/- 0.828 g/g creatinine and end of shift was 4.190 +/- 7.665 mg/g creatinine. Difference of urinary TdGA between end of shift to before shift was 3.662 +/- 7.865 mg/g creatinine. In NIOSH method, correlation coefficient between 8hour-time weighted average (8hrs-TWA) and urinary concentration of TdGA was r=0.666. and last period vinyl chloride level (6th-TWA) and urinary TdGA concentration was r=0.972. In OSHA method, correlation coefficient between last period vinyl chloride level (6th-TWA) and urinary concentration of TdGA was r=0.976 and this was highest value. CONCLUSION: There was no statistically significant difference in NIOSH method and. OSHA method. A correlation were found between level of vinyl chloride exposure and urinary thiodiglycolic acid excretion. Also, vinyl chloride exposure had significantly effected on the urinary thiodiglycolic acid excretion.

PURPOSE: To retrieve the retracted flexor tendon, additional incision and wide dissection are conventionally required. We introduce minimal-incision tenorrhaphy using 1cm-long incision and minimal dissection. METHODS: Transverse incision about 1cm in length is made over the level of retracted tendon. Nelaton's catheter is advanced into tendon sheath from distal primary laceration wound to emerge proximally through the incisional wound. A catheter is sutured to proximal tendon in end-to- end fashion. By gently pulling the catheter, retracted tendon is delivered to distal wound. Tenorrhaphy with core suture and epitendinous suture is then carried out. RESULTS: This retrieving technique provides minimal incision, minimal dissection, minimal bleeding, minimal injury to tendon end, and shorter operation time with preservation of vincula tendinum and pulley system. CONCLUSION: In case of flexor tendon rupture with retraction, this operative method is believed to allow reliable and effective tenorrhaphy and excellent postoperative outcomes.

PURPOSE: There are various approaches for open reduction surgery for orbitozygomatic fractures. After the incisions are performed, patients might have various complications. In this point of view, we conducted a retrospective study of the usability of infraorbital incision on elderly patients, generally more vulnerable to scleral show and ectropion. METHODS: In this study, 20 patients who are relatively more vulnerable to scleral show and ectropion through snap-back test having infraorbital incision were reviewed. We monitored the duration of the surgery, and complications resulted from the incision. We evaluated the scars with the researcher's observations and with the patient's level of satisfaction on a scale of 1 to 5. RESULTS: On average, 5 minutes was spent between the skin incision and the fracture exposure. No case of scleral show and ectropion occurred. One year follow-up observation revealed 4 cases of visible scars, 9 cases of barely visible scars, and 7 cases of invisible scars. The subjective satisfaction level of the patients' scar is an average of 4.0. CONCLUSION: Infraorbital incision has many advantages. First, it can reduce the complications such as scleral show and ectropion. Second, it can shorten the operation time. Third, it can diminish incision-related scars.

A patient presenting with the characteristic clinical features of the dementia of Pick's type is described, in whom neuropathological examination of brain biopsy material revealed atypical features, including extensive subcotical gliosis with mild cortical neuronal loss and without any neuronal cytoskeletal inclusions (Pick bodies, neurofibrillary tangles, and Lewy bodies) and amyloid deposits (senile plaques). And she has the suggestive family history of the same clinical features in her two brothers. So, the clinical and pathological features are discussed with particular reference to typical Alzheimer's disease and Pick's disease, and it is proposed that the case should be classified as familial progressive subcortical gliosis.
