Causes of necrotic features in fine-needle aspirates from cervical lymph nodes

Background@#Lymph node fine-needle aspiration (LN FNA) cytology indicates necrosis in various diseases. Dominant necrotic features make the diagnosis of underlying conditions very difficult. @*Methods@#We retrospectively reviewed 460 patients who underwent cervical LN aspiration cytology that revealed necrotic findings at Keimyung University Dongsan Hospital in Daegu, Korea, from 2003–2017. Each specimen was evaluated and analyzed in association with the clinical findings, biopsy findings, and/or other ancillary tests, including acid-fast bacilli staining and molecular testing for Mycobacterium tuberculosis. @*Results@#When necrotic features were noted upon cervical LN FNA cytology, the most common pathologic LN FNA category was necrosis alone (31.5%). The second most common category was granulomatous inflammation (31.3%), followed by Kikuchi disease (20.0%) and malignant neoplasm (8.7%). In cases where the cervical LN FNA revealed necrosis alone, the most common final diagnosis was tuberculosis. In young patients, Kikuchi disease should be considered as one cervical LN FNA category, while metastatic carcinoma should be suspected in older patients. @*Conclusions@#Even when necrosis alone is observed in LN FNA cytology, it is important to determine the cause through further evaluation.

Correlation between the size of the ureter stone and the neutrophil-lymphocyte ratio, platelet lymphocyte ratio, and C-reactive protein in patients with ureter stone visiting the emergency department

Objective@#The size and location of ureter stones are important factors in their spontaneous passage. We compared the clinical characteristics and neutrophil-lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and C-reactive protein (CRP) of patients who visited the emergency department with ureter stones of ≥5 mm and <5 mm in size. @*Methods@#We retrospectively reviewed 699 patients who visited the emergency department of two medical centers from January 2017 to December 2019. We compared microscopic hematuria, pyuria, NLR, PLR, CRP, the grade of hydronephrosis, and the location of ureteral calculi between the two groups. @*Results@#There were 419 patients with ureter stones less than 5 mm and 280 patients with stones more than 5 mm in size. NLR was 2.82 (1.44-4.73) and 3.12 (1.94-5.75) in patients with stones <5 mm and ≥5 mm, respectively (P=0.001). PLR was 117.2 (88.2-164.9) and 136.0 (98.9-199.7) in patients with stones <5 mm and ≥5 mm, respectively (P=0.001). CRP was 0.29 (0.29-0.29) and 0.29 (0.29-1.04) in patients with stones <5 mm and ≥5 mm, respectively (P<0.001). The proportion of microscopic hematuria was 84.7% and 76.4% in patients with stones <5 mm and ≥5 mm, respectively (P=0.006). The proportion of pyuria was 20.5% and 41.8% in patients with stones <5 mm and ≥5 mm, respectively (P=0.01). @*Conclusion@#In patients with ureter stones ≥5 mm, CRP, NLR, and PLR were significantly higher than patients with ureter stones <5 mm. However, further studies are needed before using these indicators to make clinical decisions regarding ureteral stone management.

Biomechanical function of the anterolateral ligament of the knee: a systematic review

Background@#It has been suggested that the anterolateral ligament (ALL) is an important anterolateral stabilizer of the knee joint which functions to prevent anterolateral subluxation and anterior subluxation at certain flexion angles in the knee. Purpose: To analyze and systematically interpret the biomechanical function of the ALL. @*Methods@#An online search was conducted for human cadaveric biomechanical studies that tested function of the ALL in resisting anterolateral subluxation and anterior subluxation of the knee. Two reviewers independently searched Medline, Embase, and the Cochrane Database of Systematic Reviews for studies up to 25 September 2018. Biomechanical studies not reporting the magnitude of anterior tibial translation or tibial internal rotation in relation to the function of the ALL were excluded. @*Results@#Twelve biomechanical studies using human cadavers evaluating parameters including anterior tibial translation and/or internal tibial rotation in anterior cruciate ligament (ACL)-sectioned and ALL-sectioned knees were included in the review. Five studies reported a minor increase or no significant increase in anterior tibial translation and internal tibial rotation with further sectioning of the ALL in ACL-deficient knees. Five studies reported a significant increase in knee laxity in tibial internal rotation or pivot shift with addition of sectioning the ALL in ACL-deficient knees. Two studies reported a significant increase in both anterior tibial translation and internal tibial rotation during application of the anterior-drawer and pivot-shift tests after ALL sectioning. @*Conclusion@#There was inconsistency in the biomechanical characteristics of the ALL of the knee in resisting anterolateral and anterior subluxation of the tibia.

Distal Femoral Medial Opening Wedge Osteotomy for Post-Traumatic, Distal Femoral Varus Deformity

Restoration of neutral mechanical alignment of the lower limb is an important factor in the treatment of unicompartmental arthrosis. Traditionally, medial opening wedge high tibial osteotomy has been widely performed to correct varus malalignment with unicompartmental arthrosis. However, an ideal indication for the high tibial osteotomy is the knee with metaphyseal tibial varus malalignment. The basic principle of corrective osteotomy is performing an osteotomy at the center of the deformity to prevent abnormal joint line obliquity. If pathologic distal femoral varus deformity is the cause of genu varum, the osteotomy should be performed in the distal femur. Reports of medial opening wedge distal femoral osteotomy (DFO) to correct varus malalignment are rare. We present a case of this very rare and challenging condition in a 47-year-old male, which was successfully treated by medial opening wedge DFO.

Clinical significance of microscopic hematuria and hydronephrosis in ureteral calculi patients visiting emergency department

OBJECTIVE: This study examined the clinical significance of microscopic hematuria and grade of hydronephrosis in ureteral calculi patients visiting the emergency department (ED). METHODS: The EDs of two medical centers were reviewed retrospectively from August 1, 2012 to July 31, 2017. The total ureteral calculi patients were 2,069 and 1,593 patients were analyzed after exclusion. The normal range of microscopic hematuria in both medical centers was 0–5/high power field (HPF) of red blood cell in urinalysis. Therefore, microscopic hematuria more than 5/HPF was defined as positive. The size of the stone, grade of hydronephrosis (normal, mild, moderate, and severe) and location of ureteral calculi in the non-contrast abdomen and pelvis computed tomography (CT) was measured by one person at each medical center using same method. The patients with or without microscopic hematuria and grade of hydronephrosis were then compared. RESULTS: The median size of the ureteral calculi patients without and with microscopic hematuria was 5.4 mm (range, 3.8–9.0 mm) and 4.0 mm (range, 3.0–5.8 mm) (P < 0.001). The patients grouped as normal to mild, and moderate to severe hydronephrosis, without microscopic hematuria was 191 (16.5%) and 91 (20.9%), respectively. On the other hand, microscopic hematuria was 966 (83.5%) and 345 (79.1%) (P=0.042). According to the location of ureteral calculi, with and without microscopic hematuria was 81.9% and 18.1% in the upper ureter, 82.9% and 17.1% in the mid ureter, and 82.6% and 17.4% in the lower ureter, respectively (P=0.935). CONCLUSION: The median size of the stone and grade of hydronephrosis were related to microscopic hematuria but the location of the ureteral calculi was not related. Therefore, in cases without microscopic hematuria in suspected ureteral calculi, clinicians should check the abdomen and pelvis CT for an accurate diagnosis and treatment of ureteral calculi.

A Comparison between Clinical Results of Selective Bundle and Double Bundle Anterior Cruciate Ligament Reconstruction

PURPOSE: The purpose of this study was to compare the clinical outcomes of arthroscopic anatomical double bundle (DB) anterior cruciate ligament (ACL) reconstruction with either selective anteromedial (AM) or posterolateral (PL) bundle reconstruction while preserving a relatively healthy ACL bundle. MATERIALS AND METHODS: The authors evaluated 98 patients with a mean follow-up of 30.8±4.0 months who had undergone DB or selective bundle ACL reconstructions. Of these, 34 cases underwent DB ACL reconstruction (group A), 34 underwent selective AM bundle reconstruction (group B), and 30 underwent selective PL bundle reconstructions (group C). These groups were compared with respect to Lysholm and International Knee Documentation Committee (IKDC) score, side-to-side differences of anterior laxity measured by KT-2000 arthrometer at 30 lbs, and stress radiography and Lachman and pivot shift test results. Pre- and post-operative data were objectively evaluated using a statistical approach. RESULTS: The preoperative anterior instability measured by manual stress radiography at 90° of knee flexion in group A was significantly greater than that in groups B and C (all p<0.001). At last follow-up, mean side-to-side instrumented laxities measured by the KT-2000 and manual stress radiography were significantly improved from preoperative data in all groups (all p<0.001). There were no significant differences between the three groups in anterior instability measured by KT-2000 arthrometer, pivot shift, or functional scores. CONCLUSION: Selective bundle reconstruction in partial ACL tears offers comparable clinical results to DB reconstruction in complete ACL tears.

Parosteal Lipoma in the Metatarsus: A Case Report / 대한족부족관절학회지

We experienced a rare case of parosteal lipoma, which located on the periosteum of the foot 4th metatarsus. A 22-year-old woman visited the hospital with painful mass in her foot. Based on the assessment of plain radiographs, computed tomography scan, and magnetic resonance image, it was suspected as lipoma. Marginal excision was performed and parosteal lipoma was confirmed histologically. Any local recurrence and complications were not observed in 2 years after surgery.

Clinical efficacy review on cases of laparoscopic myomectomy / 대한산부인과내시경학회지

OBJECTIVE: To report the safety and clinical efficacy of laparoscopic myomectomy. METHODS: We analyzed retrospectively the data for 74 laparoscopic myomectomy performed at Inje University Busan Paik Hospital beween 2005 and 2009. With medical records, we analyzed data on the patient's age, parity, BMI, size, weight and location of myoma, previous operative history, preoperative indication, operating time, blood loss, change of hemoglobin concentration from preoperative to postoperative state, hospital stay. RESULTS: The mean age of the patients was 39.5+/-6.9 years, parity was 1.4+/-1.0 and BMI was 22.1+/-2.6 kg/m2. The size of myoma by preoperative ultrasonography was 5.2+/-1.9 cm, the weight of removed myoma was 95.1+/-88.1 g. Most myomas were subserosal and intramural type. The operating time was 95.9+/-34.4 minutes, the change of hemoglobin concentration was 1.3+/-0.78 g/dL, and the hospital stay was 4.7+/-1.1 days. Postoperatively, transfusion was done in 2 cases, one patient was pregnant and underwent an cesarean section delivery during follow-up. CONCLUSION: Laparoscopic myomectomy was performed regardless of the size, the location of the myoma or the previous operative history and had good outcomes without complications in our hospital. Laparosocpic myomectomy is considered safe and reliable procedure in various types of myoma.

Comparison and Efficacy of Low-Dose and Standard-Dose Tamsulosin and Alfuzosin in Medical Expulsive Therapy for Lower Ureteral Calculi: Prospective, Randomized, Comparative Study

PURPOSE: Typically in Korea, for a standard dose (0.4 mg) of tamsulosin, two low doses (0.2 mg) are administered. The aim of this study was to evaluate and compare the efficacy of tamsulosin (0.2 mg and 0.4 mg) and alfuzosin (10 mg) in the treatment of lower ureteral stones. MATERIALS AND METHODS: A total of 141 patients presenting with a single 4- to 10-mm sized lower ureteral stone were randomly assigned to 4 groups. Patients in group 1 (n=41) and group 2 (n=30) received an oral dose of 0.2 mg tamsulosin once and twice daily, respectively, and patients in group 3 (n=36) received a daily oral dose of 10 mg alfuzosin. Patients in group 4 (n=34) received trospium chloride only. The spontaneous passage of stones, the stone expulsion time, and adverse effects were evaluated. RESULTS: There were no significant differences in patient background, including age, sex, BMI, stone size, stone side, and symptom duration. The spontaneous stone passage rate through the ureter was higher and the stone expulsion time was faster in groups 1, 2, and 3 than in group 4. There were no statistically different changes in groups 1, 2, and 3. The adverse effects observed in all groups were comparable and were mild. CONCLUSIONS: Tamsulosin at 0.2 mg and 0.4 mg and alfuzosin (10 mg) proved to be safe and effective. A first cycle of medical expulsive therapy with tamsulosin 0.2 mg could be considered as an option in the management of single lower ureteral stone.

Changes of Endothelin-1 in Rats Corpus Cavernosum Smooth Muscle of Partial Bladder Outlet Obstruction / 대한남성과학회지

PURPOSE: Lower urinary tract symptoms and erectile dysfunction (ED) are common disorders in men and increase with age. Recently, there has been evidence to suggest that patients with high benign prostatic hyperplasia symptom scores have an increased frequency of ED. This study was performed to evaluate the change of the expression of endothelin-1 (ET-1) in the corpus cavernosum by inducing partial bladder outlet obstruction (PBOO) in a rat model. MATERIALS AND METHODS: Eight Sprague-Dawley male rats were used for induction of PBOO by placing a 25 gauge angioneedle sheath around the urethra, then ligating the bladder neck with 3-0 vicryl suture and six sham-operated rats were ligated very loosely without causing obstruction. At three and five weeks after PBOO, the distal portion of the ligated penile tissues was dissected for immunohistochemical staining of ET-1 in the vascular endothelial cell. RESULTS: ET-1 was weakly expressed (+) in the smooth muscle layers of the control group and a very strong expressed (++++) in the experimental group on 3 weeks after PBOO. However, there was no expression in the experimental group on 5 weeks after PBOO. There was no expression (-) in the vascular endothelial cells of the control group and very strong expression (++++) in the experimental group on 3 weeks after PBOO. Howerver, there was no expression in the experimental group on 5 weeks after PBOO. CONCLUSIONS: The changes of penis by inducing partial bladder outlet obstruction in the rats were associated with increased ET-1 in the vascular and peri-vascular smooth muscle cells of the corpus cavernosum.

Apoptotic Effects of Genistein, Biochanin-A and Apigenin on LNCaP and PC-3 Cells by p21 through Transcriptional Inhibition of Polo-like Kinase-1

Natural isoflavones and flavones are important dietary factors for prostate cancer prevention. We investigated the molecular mechanism of these compounds (genistein, biochanin-A and apigenin) in PC-3 (hormone-independent/p53 mutant type) and LNCaP (hormone-dependent/p53 wild type) prostate cancer cells. A cell growth rate and apoptotic activities were analyzed in different concentrations and exposure time to evaluate the antitumor activities of genistein, biochanin-A and apigenin. The real time PCR and Western blot analysis were performed to investigate whether the molecular mechanism of these compounds are involving the p21 and PLK-1 pathway. Apoptosis of prostate cancer cells was associated with p21 up-regulation and PLK-1 suppression. Exposure of genistein, biochanin-A and apigenin on LNCaP and PC-3 prostate cancer cells resulted in same pattern of cell cycle arrest and apoptosis. The inhibition effect for cell proliferation was slightly greater in LNCaP than PC-3 cells. In conclusion, flavonoids treatment induces up-regulation of p21 expression, and p21 inhibits transcription of PLK-1, which promotes apoptosis of cancer cells.

High Transcript Level of FLT3 Associated with High Risk of Relapse in Pediatric Acute Myeloid Leukemia

Identification of prognostic factors and risk-based post-remission therapy was proposed to improve the outcomes of acute myeloid leukemia (AML) and a mutation of FLT3 has been reported to be a risk factor, especially for pediatric patients. Recently, FLT3 expression level was implicated to have prognostic significance in adults, but little is known for childhood AML. To define the prognostic significance, transcript level of FLT3 was analyzed in 52 pediatric AML patients. The median copy number of FLT3 was 4.6x10(3) (40-5.9x10(7) copies)/1.0x10(6) GAPDH copy, and the relapse free survival of patients with high transcript level of FLT3 (>10(6) copy number) (0%) was significantly lower than that of the others (53.2%). High transcript level of FLT3 was associated with a markedly high risk of relapse. The development of new therapeutic scheme such as a frontline allogeneic stem cell transplantation or administration of FLT3 inhibitor is needed to improve outcomes.

Induction of hypoxia-inducible factor-1alpha inhibits drug-induced apoptosis in the human leukemic cell line HL-60 / 대한혈액학회지

BACKGROUND: Leukemic cells originate from hypoxic bone marrow, which protects them from anti-cancer drugs. Although many factors that cause drug resistance in leukemic cells have been studied, the effect of hypoxia on drug-induced apoptosis is still poorly understood. METHODS: In this study, we examined the effect of hypoxia on anti-leukemic drug resistance in leukemic cell lines treated with cobalt chloride (CoCl2), a hypoxia-mimetic agent. Cellular proliferation was evaluated using the methyl thiazolyl tetrazolium (MTT) assay. Flow cytometry analysis and western blots were performed to investigate apoptosis-related proteins. RESULTS: Unlike its previously known apoptotic effect, the expression of HIF-1alpha increased the survival rate of human promyelocytic leukemia HL-60 cells when these cells were exposed to anti-leukemic drugs; these effects were mediated by heat-shock protein HSP70 and the pro-apoptotic protein Bax. CONCLUSION: These findings may provide new insights for understanding the mechanisms underlying hypoxia and for designing new therapeutic strategies for acute myeloid leukemia.

Paraganglioma of a Bladder with a Bladder Stone

Paragangliomas of the urinary bladder are very rare tumors of the paraganglion system that arise from chromaffin cells in or near the sympathetic ganglia. Only approximately 15% of them develop from extra-adrenal chromaffin tissue. Most of these tumors are hormonally active and secrete mainly noradrenaline (rarely adrenaline), calcitonin, and adrenocorticotropic hormone. Paragangliomas are generally benign tumors, with less than 10% being malignant. Here we report a case of a paraganglioma arising in a urinary bladder with a bladder stone.

Comparison of the Efficacy of a Terpene Mixture and Alpha-Blocker for Treatment of Category III Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Prospective Study

PURPOSE: The aim of this study was to evaluate the efficacy of a terpene mixture compared with alpha-blocker in patients with chronic pelvic pain syndrome (CPPS). MATERIALS AND METHODS: Patients diagnosed with CPPS were included in this study. The patients were randomly placed into three groups. Group 1 was treated with levofloxacin alone (36 patients), group 2 was treated with levofloxacin and alfuzosin (33 patients), and group 3 was treated with levofloxacin and terpene mixture (34 patients) for 8 weeks. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was evaluated in patients in each group at the beginning of the study and after 8 weeks of treatment. RESULTS: Pain domain, urinary domain, quality of life domain, and total score on the NIH-CPSI were not significantly different at the initial visit. After treatment with each medication, improvements on the pain domain and total score of the NIH-CPSI were better in group 3 than in group 1 or group 2 (p<0.05). Improvement on the urinary domain of the NIH-CPSI was better in group 2 than in group 1 or group 3 (p=0.014). Changes in the quality of life domain of the NIH-CPSI were not significant among the three groups. CONCLUSIONS: This study suggests that the terpene mixture and alpha-blockers may have significant benefit for symptomatic relief, especially in the pain and urinary domains, respectively.

Effect of Level of Spinal Cord Injury and Urinary Catheterization on Sexual Function and Activity in Male Patients with Upper Motor Neuron Injury

PURPOSE: We investigated the effect of the level of spinal cord injury and urinary catheterization on sexual function and activity in male patients with upper motor neuron (UMN) injury. MATERIALS AND METHODS: We reviewed patient's chart, radiologic and urodynamic study. We interviewed patient's sexual activity according to educational status, economic and marriage state, occupation, duration of spinal cord injury and pattern of voiding. A total of 114 male patients with neurogenic bladder due to UMN injury were included in the study. Group 1 consisted of 33 patients who underwent a clean intermittent catheterization (CIC) regimen and group 2 consisted of 81 patients with a suprapubic catheter, condom catheter, or Foley catheter. A detailed sexual behavior was taken for all patients to complete a questionnaire including the 5-item version of the International Index of Erectile Function (IIEF-5). RESULTS: Satisfaction with intercourse (p=0.037) and total score (p=0.032) on the IIEF-5 were significantly higher in group 1 than in group 2. The other items on the IIEF-5 did not differ significantly between the groups. When the subjects were stratified according to level of spinal cord injury, 8 patients (18.6%) with cervical cord injury had no sexual activity, whereas 24 patients (33.8%) with non-cervical-cord injury did (p=0.048). Patients with no sexual activity were 12.1% (4/33) of the patients in the CIC group and 34.6% (28/81) of the patients who underwent other regimens (p=0.016). CONCLUSIONS: Our results demonstrate that level of spinal cord injury and urinary catheterization may influence the sexual activity of male patients with UMN injury. Our results suggest that the CIC regimen had a positive effect on the sexual activity of these patients.

Comparison of the Urinary Melanoma Antigen Gene Expression (MAGE) Test and Urinary Cytology for Bladder Cancer Screening

PURPOSE: In bladder cancer screening, many methods such as urinary cytology, bladder tumor antigen, and nuclear matrix protein-22 are well known. To learn the value of urinary melanoma antigen gene expression (MAGE) in bladder cancer screening, we compared the urinary MAGE test with irrigated urinary cytology. MATERIALS AND METHODS: From July 2000 to July 2007, a total of 142 patients were enrolled in this study. We divided these patients into 2 groups. Eighty-eight patients with bladder cancer were included in group I. Group II consisted of 54 patients who had been treated for bladder cancer and had no evidence of tumor by cystoscopy and irrigated urinary cytology. Urinary cytology, urinary MAGE test, and cystoscopy were performed in all patients. The urinary MAGE test was done by reverse transcriptase polymerase chain reaction (RT-PCR). Sensitivity and specificity were investigated according to cancer grade and stage. RESULTS: The overall sensitivity of the urinary MAGE test and urinary cytology was 69.3% (61/88) and 53.4% (47/88), respectively (p=0.03). The specificity of the urinary MAGE test and urinary cytology was 75.9% (41/54) and 83.3% (45/54), respectively (p=0.34). The sensitivity of each test in superficial tumors (Ta, T1) was 65.5% (38/58) and 46.6% (27/58), respectively (p=0.04). In advanced disease (> or =T2), the sensitivity of the tests was 76.7% (23/30) and 66.7% (20/30), respectively (p=0.39). The sensitivity of the urinary MAGE test in grade 1 tumors (60.5%, 23/38) was significantly higher (p=0.01) than that of urinary cytology (31.6%, 12/38). CONCLUSIONS: The urinary MAGE test was more sensitive than urinary cytology in bladder cancer screening. We consider the urinary MAGE test to possibly be a valuable test together with urinary cytology, especially for Grade 1 and Ta, T1 bladder cancer.

The Effect of Tolterodine and Oxybutyninin on Nocturia in Patients with Benign Prostatic Hyperplasia

PURPOSE: Nocturia has been one of the most bothersome symptoms in benign prostatic hyperplasia (BPH) patients. Therefore, the authors evaluated the effect of tolterodine and oxybutyninin on nocturia in BPH patients. MATERIALS AND METHODS: From September 2006 to March 2007, 82 patients who presented over than 2 in nocturnal bladder capacity index (NCBI) in spite of having alpha blockers for 6 months were enrolled. Group I (n=38) took alpha blocker with tolterodine, group II (n=44) took alpha blocker with oxybutynin. The number of their nocturia episodes was separately evaluated by the time before and after the medication. The complications were assessed using a questionnaire. RESULTS: The number of nocturia episodes decreased by at least 1 in 68.4% (26/38), 84.1% (37/44) of patients in group I, II, respectively, and decreased by 2 or more, 1 and were unchanged or increased were 36.8, 31.6, 31.6% in group I patients and 45.5, 38.6, 15.9% in group II patients, respectively. In baseline nocturia > or =6 group, the nocturia decreased by 1 or more in 66.7%, 77.8% in group I, II, respectively. Adverse events, including dry mouth, dizziness, headache, etc, occurred in 21.1% (8/38) in group I and 27.3% (12/44) in group II patients. The complications between two groups showed no significant differences. CONCLUSIONS: Alpha blockers with tolterodine or oxybutynin can be effectively combined as a treatment option for patients with BPH complaining of unresolved nocturia.

Gastrocnemius Muscle Length and Velocity During Gait in Patients with Planovalgus Foot Deformity in Cerebral Palsy / 대한정형외과연구학회지

PURPOSE: Patients with planovalgus show various abnormal gaits and these are affected by the different length and velocity of the muscles around knee and ankle. The purpose of study is to compare the length and velocity of gastrocnemius in cerebral palsy with planovalgus by ankle plantarflexion-knee extension couple. MATERIALS AND METHODS: 22 patients with spastic diplegia who have planovalgus were included. The mean age was 12 years (5 years~18 years). Group I consisted of 7 patients with knee flexion more than 30 degrees and Group II consisted of 15 patients with knee flexion less than 15 degrees during mid-stance phase. Normal groups were consisted of 15 normal children. RESULTS: In patients with planovalgus, ankle dorsiflexion during stance was decreased but ankle plantarflexion was not different compared to normal. There is no difference in the percent length of gastrocnemius compared to normal, but the velocity was decreased. The percent length of gastrocnemius was decreased in group I, but there were no difference in the velocity. CONCLUSION: The decreased velocity of gastrocnemius is the cause of disability of ankle plantarflexion-knee extension couple and the variable length of gastrocnemius is the cause of variability of abnormal gait.

A Case of Pa-tient with Wegener's Granulomatosis Showing Glomerular Immune Deposition in Kidney Biopsy / 대한신장학회지

Rapidly progressive glomerulonephritis (RPGN) in Wegener's granulomatosis patients typically has been characterized by pauci-immune glomerulonephritis (PIGN). In some patients, however, significant amount of glomerular immune deposits was detected and reported that they may have poor prognosis. A 30 year-old-female visited due to the skin rash of both lower extremities, arthralgia and nasal stiffness. She had sinusitis, lung opacity, and proteinuria. Serologic PR-3 ANCA was positive and histologic findings of nasal cavity and lung also showed necrotizing vasculitis and granuloma. Thus we could diagnose Wegener's granulomatosis. However, gross hematuria developed and renal function worsened in spite of treatment with high dose prednisolone and oral cyclophosphamide. Therefore we performed a kidney biopsy. The kidney biopsy showed crescentic glomerulonephritis with Ig A deposition in the mesangium. We experienced a case of Wegener's granulomatosis patient with significant IgA deposition in glomeruli. We report this case with brief review of the literature.
