Computed tomographic features of focal lipogranulomatous lymphangitis for differentiating from malignant intestinal lesions in a dog

An eight-year-old Maltese dog presented with diarrhea and anorexia. Ultrasonography revealed marked focal wall thickening with loss of layering in the distal ileum. Contrast-enhanced computed tomography (CT) revealed a preserved wall layer with hypoattenuating middle wall thickening. In some segments of the lesion, small nodules protruding toward the mesentery from the outer layer were observed. Histopathology revealed focal lipogranulomatous lymphangitis (FLL) with lymphangiectasia. This is the first report to describe the CT features of FLL in a dog. CT features of preserved wall layers with hypoattenuating middle wall thickening and small nodules can assist in diagnosing FLL in dogs.

Split-bolus CT urography with synchronous nephrographic and excretory phase in dogs: comparison of image quality with three-phase CT urography and optimal allocation ratio of contrast medium

Background@#Computed tomography urography (CTU), based on the excretion of contrast medium after its injection, allows visualization of the renal parenchyma and the renal collecting system. @*Objectives@#To determine the optimal contrast medium dose allocation ratio to apply in split-bolus CTU in dogs. @*Methods@#This prospective, experimental, exploratory study used 8 beagles. In 3-phase CTU, unenhanced-, nephrographic-, and excretory-phase images were obtained with a single injection of 600 mg iodine/kg iohexol. In split-bolus CTU, two different contrast medium allocation ratios (30% and 70% for split CTU 1; 50% and 50% for split CTU 2) were used. Unenhanced phase image and a synchronous nephrographic-excretory phase image were acquired. @*Results@#Although the attenuation of the renal parenchyma was significantly lower when using both split CTUs than the 3-phase CTU, based on qualitative evaluation, the visualization score of the renal parenchyma of split CTU 1 was as high as that of the 3-phase CTU, whereas the split CTU 2 score was significantly lower than those of the two others. Artifacts were not apparent, regardless of CTU protocol. The diameter and opacification of the ureter in both split CTUs were not significantly different from those using 3-phase CTU. @*Conclusions@#Split-bolus CTU with a contrast medium allocation ratio of 30% and 70% is feasible for evaluating the urinary system and allows sufficient enhancement of the renal parenchyma and appropriate distention and opacification of the ureter, with similar image quality to 3-phase CTU in healthy dogs. Split-bolus CTU has the advantages of reducing radiation exposure and the number of CT images needed for interpretation.

Does prostate-specific antigen (PSA) mass or free PSA mass improve the accuracy of predicting total prostate volume in relation to obesity in men with biopsy-proven benign prostatic hyperplasia? / 亚洲男科学杂志(英文版)

We evaluated whether the prostate-specific antigen (PSA) mass or free PSA (fPSA) mass (i.e., absolute amount of total circulating PSA or fPSA protein, respectively), versus serum PSA or fPSA concentration, improves the accuracy of predicting the total prostate volume (TPV) in relation to obesity. Among men whose multicore (≥12) transrectal prostate biopsy was negative, 586 who had a PSA of ≤10 ng ml-1 and underwent the fPSA test prior to biopsy were enrolled. The PSA mass or fPSA mass (μ g) was calculated by multiplying the serum level by plasma volume. At each TPV cut-off point (30 ml, 40 ml, and 50 ml), the areas under the receiver operating characteristics curve (AUCs) of each variable were compared in obesity-based subgroups. AUCs of fPSA and fPSA mass for predicting TPV were significantly larger than those for PSA and PSA mass by 8.7%-12.1% at all cut-off points. Subgroup analyses based on obesity showed that, although PSA mass and fPSA mass enhanced accuracy by 4% (P = 0.031) and 1.8% (P = 0.003), respectively, for determining TPVs of ≥30 ml and ≥50 ml in obese and overweight men, they did not improve the accuracy in most other combinations of the degrees of obesity with TPV cut-off points. Thus, compared with serum PSA or fPSA, the absolute amount of PSA or fPSA protein mass improved the accuracy of predicting TPV in obese men very minimally and only for certain TPV cut-off points. Hence, these indicators may not provide clinically meaningful improvement in predicting TPV in obese men.

The Treatment of Metastatic and Castration-Resistant Prostate Cancer Patients in Korea

The treatment of advanced prostate cancer has rapidly evolved. Androgen deprivation therapy is recognized as the first-line therapy for metastatic disease; however, a substantial proportion of patients will eventually progress to develop castration-resistance. For the past several years, docetaxel-based chemotherapy has shown significant therapeutic benefit in castration-resistant prostate cancer. Over the last 5 years, several new agents such as the enzalutamide, abiraterone, cabazitaxel, and 223radium have been developed which have all been associated with improved quality of life, pain palliation, and an increase in survival. Unfortunately, there are no Korean treatment guideline for metastatic prostate cancer and/or castration-resistant prostate cancer which has been developed based on adequate review and assessment of evidences. Thus, a guideline adequate for domestic circumstances is eagerly needed. The Korean Association for Clinical Oncology, the Korean Prostate Society, the Korean Urological Oncology Society, and the Korean Society of Pathologists reviewed and endorsed the guidelines.

Schwannoma of the Orbit

BACKGROUND: A schwannoma is a benign, slow-growing peripheral nerve sheath tumor that originates from Schwann cells. Orbital schwannomas are rare, accounting for only 1% of all orbital neoplasms. In this study, we retrospectively review orbital schwannomas and characterize clinical, radiologic, and histologic features of this rare entity. METHODS: A retrospective review was performed to identify patients with histologically confirmed orbital schwannoma, among a list of 437 patients who had visited our hospital with soft tissue masses within the orbit as the primary presentation between 2010 and 2014. Patient charts and medical records were reviewed for demographic information, relevant medical and family history, physical examination findings relating to ocular and extraocular sensorimotor function, operative details, postoperative complications, pathologic report, and recurrence. RESULTS: Five patients (5/437, 1.1%) were identified as having histologically confirmed orbital schwannoma and underwent complete excision. Both computed tomography (CT) and magnetic resonance imaging (MRI) studies were not consistent in predicting histologic diagnosis. There were no complications, and none of the patients experienced significant scar formation. In two cases, patients exhibited a mild postoperative numbness of the forehead, but the patients demonstrated full recovery of sensation within 3 months after the operation. None of the five patients have experienced recurrence. CONCLUSION: Orbital schwannomas are relatively rare tumors. Preoperative diagnosis is difficult because of its variable presentation and location. Appropriate early assessment of orbital tumors by CT or MRI and prompt management is warranted to prevent the development of severe complications. Therefore, orbital schwannomas should be considered in the differential diagnosis of slow-growing orbital masses.

Fingernail Configuration

BACKGROUND: A number of conditions can alter a person's fingernail configuration. The ratio between fingernail width and length (W/L) is an important aesthetic criterion, and some underlying diseases can alter the size of the fingernail. Fingernail curvature can be altered by systemic disorders or disorders of the fingernail itself. Although the shape and curvature of the fingernail can provide diagnostic clues for various diseases, few studies have precisely characterized normal fingernail configuration. METHODS: We measured the W/L ratio of the fingernail, transverse fingernail curvature, hand length, hand breadth, and distal interphalangeal joint width in 300 volunteers with healthy fingernails. We also investigated whether age, sex, height, and handedness influenced the fingernail W/L ratio and transverse fingernail curvature. RESULTS: In women, fingernail W/L ratios were similar across all five fingers, and were lower than those in men. The highest value of transverse fingernail curvature was found in the thumb, followed by the index, middle, ring, and little fingers. Handedness and aging influenced transverse fingernail curvature, but not the fingernail W/L ratio. Fingernails were flatter on the dominant hand than on the non-dominant hand. The radius of transverse fingernail curvature increased with age, indicating that fingernails tended to flatten with age. CONCLUSIONS: Our quantitative data on fingernail configuration can be used as a reference range for diagnosing various diseases and deformities of the fingernail, and for performing reconstructive or aesthetic fingernail surgery.

Effect of the Emergency Trauma Team's Management on the Treatment of Patients with Multiple Severe Trauma

PURPOSE: We performed this study to determine how the emergency trauma team affects the treatment of patients with multiple severe trauma and to discuss the effect and the direction of the emergency trauma team's management. METHODS: We performed a retrospective analysis of 518 patients who visited our emergency department with severe trauma from August 2006 to July 2008. We divided the severe trauma patients into 2 groups : patients before and after trauma team management (Group 1 and Group 2). Then, we compared demographic characteristics, mechanisms of injury, and treatment outcomes (lengths of stay in the ED, admission ratio, and in-hospital mortality) between the 2 groups. In the same way, patients with multiple severe trauma were divided into 2 groups, that are patients before and after trauma team management (Group 3 and Group 4) and analyzed. RESULTS: There was no significant difference, except mean age, between groups 1 and 2. In group 4 patients, compared to group 3 patients, the lengths of stay in the ED were lower (p value < 0.001), and the admission ratio were higher (p value = 0.017), but there was no significant difference in the in-hospital mortality between the groups 3 and 4. CONCLUSION: When patients with multiple severe trauma visit the ED, the emergency trauma team's management can decrease the lengths of stay in the ED and increase the admission ratio, but does not produce a decrease in the in-hospital mortality rate. Further investigations of emergency trauma team management are needed to improve treatment outcomes for patients with multiple severe trauma.

The Prognostic Significance of Anatomical Resection for Small Hepatocellular Carcinoma

PURPOSE: There has been controversy concerning which is the best treatment method for small hepatocellular carcinoma between anatomical resection (AR) and non-anatomical resection (NAR). In this retrospective study, we investigated the outcomes of surgical resection for small hepatocellular carcinoma and the clinical results depending on the type of hepatectomy. METHODS: We performed an analysis of the clinicopathologic factors of forty eight patients who underwent hepatectomy for a small (<2 cm) hepatocellular carcinoma between 1990 and 2005. The AR was defined as the resection based on the segment or lobe, as proposed by Couinaud. NAR was defined as the resection of a lesion without regard to the segmental or lobar anatomy, as proposed by Couinaud. The patients were divided into 2 groups base on the hepatectomy procedure: AR (n=24) and NAR (n=24). RESULTS: There were no significant difference between the two groups for the general characteristics of the patients and the clinicopathologic findings, except for ICG R15. The mean ICG R15 in the AR and NAR groups was 11.8+/-6.9 and 22.4+/-15.6, respectively, The NAR group had significantly higher ICG R15 values. The cumulative 1, 3 and 5 year overall survival rates in the AR and NAR groups were 95.8%, 68.2% and 61.3%, and 76.6%, 59.0% and 52.5%, respectively. The cumulative overall survival rate and the mean 5 year disease free survival rate in the AR group (69.8%) were higher than those of the NAR group (45.8%). However, there was no statistically significant difference. CONCLUSION: Depending on the surgical results of this study, there was no statistically significant difference in the outcomes between the AR and NAR groups.

A Case of Lipoid Pneumonia Induced by Aspiration of Shark Liver Oil / 소아알레르기및호흡기학회지

Lipoid pneumonia, a rare disease entity, results from accumulation of lipids in the alveoli. It results from the aspiration of vegetable, animal oil or mineral oil. Squalene is a derivative of shark liver oil that is taken as a traditional remedy in some Asian counties and is used widely also in cosmetics. Although many cases with predisposing factors have been reported, lipoid pneumonia can occur in normal individuals without predisposing factors. A 2-year-old boy was admitted to the hospital with a history of fever and cough for during 2 weeks. On physical examination, his lung sound was decreased in the right lung field. He was found to have infiltrate in the right upper lobe, middle and lower lung field on a chest radiograph. His parents fed him with squalene. High resolution computed tomography scan of the chest showed 'Crazy-paving appearance' in the right upper, middle and lower lobes. Lipoid pneumonia is suggested when there is a history of oil- or lipid- based product use or consumption. The characteristic finding of lipid materials, 'Crazy-paving appearance' in chest Computed Tomography (CT) or chest Magnetic Resonance Image (MRI), may be useful in the diagnosis of lipoid pneumonia. We report the case of lipoid pneumonia of a 2-year-old healthy child with a history of squalene.

Clinical Investigation of Children with Severe Atopic Dermatitis / 소아알레르기및호흡기학회지

PURPOSE: We attempted to investigate clinical characteristics of children with severe atopic dermatitis. METHODS: A total of 204 children diagnosed with Atopic dermatitis at the Pediatric Allergy Respiratory Center in Busan St. Mary's Medical Center from June 2006 to June 2008 were enrolled in this study. Cases were divided into 3 groups according to SCORAD index: severe, moderate and mild groups. We collected birth, environment, and allergic family history, and tested serum IgE, total eosinophil count, specific IgE, ECP (Eosinophil Cationic Protein) and the SCORAD index between the 3 groups. RESULTS: Of the 204 patients, 100 (49.02%) were included in the severe group, 51 (25.0%) in the moderate group, and 53 (25.98%) in the mild group. There were no differences in serum total IgE, serum total eosinophil counts and ECP between the severe and moderate groups. Serum total IgE, serum total eosinophil counts and ECP were relatively higher in the severe group than mild group. Food allergen sensitization rate was relatively higher in the infantile severe group than in the childhood severe group, while inhalant allergen sensitization rate was relatively higher in the childhood severe group than in the infantile severe group. There was no correlation between serum total IgE, serum total eosinophil counts, ECP and the number of sensitized allergens relative to SCORAD index in the severe group. CONCLUSION: Serum IgE, total eosinophil count, specific IgE and ECP may be specific indicators of children with severe atopic dermatitis. Further studies are needed to determine a clear distinction between severe and moderate atopic dermatitis patients.

Laparoscopic Radical Prostatectomy: The Intraoperative and Perioperative Complications in 150 Cases / 대한비뇨기과학회지

PURPOSE: We retrospectively evaluated the intraoperative and perioperative complications of 150 laparoscopic radical prostatectomies that were performed at our institution. MATERIALS AND METHODS: Between July 2001 and March 2007, 150 consecutive patients underwent laparoscopic radical prostatectomy. The inpatient and outpatient medical records were reviewed. We divided the patients into three groups: the first 50 patients in group I, the middle 50 patients in group II and last 50 patients in group III. The major and minor complications were evaluated in each group. RESULTS: The overall complication rate was 36%. The major complication rate was 7% and the minor complication rate was 29%. The major complication rate was 18% in group I, 2% in group II and 0% in group III. The minor complication rate was 48% in group I, 24% in group II and 16% in group III. The result showed that the complication rate declined with accumulating experience with laparoscopic radical prostatectomy(p<0.05). CONCLUSIONS: Although laparoscopic radical prostatectomy is a technically demanding procedure and it has a steep learning curve, the complication rate declined with accumulating experience with laparoscopic radical prostatectomy. The complications were acceptable because they were not severe and they were managed with little difficulty.

Laparoscopic Excision of a Giant Bladder Diverticulum / 대한비뇨기과학회지

Bladder diverticulum is a herniation of the bladder mucosa through the bladder wall musculature. Traditionally, bladder diverticulum has been excised by the open surgical method. However, laparoscopic technique has been widely used to treat many urologic diseases, including bladder diverticulum. Laparoscopic diverticulectomy can be performed transperitoneally or extraperitoneally. We report here on our experience with transperitoneal laparoscopic diverticulectomy.

Feasibility and Safety of Performing Hand-assisted Laparoscopic Donor Nephrectomy for Patients with Multiple Renal Arteries / 대한비뇨기과학회지

PURPOSE: We wanted to present the feasibility and safety of hand-assisted laparoscopic donor nephrectomy(HALDN) for treating patients with multiple renal arteries. MATERIALS AND METHODS: Between February 2000 and July 2006, 252 patients underwent HALDN. The results for the patients with a single renal artery (n=187)(Group I) and those patients with multiple renal arteries(n=65) (Group II) were compared in terms of the donor and recipient outcomes. A retrospective chart review was performed and statistical analysis included Student's t-test, the chi square test and Kaplan-Meier survival probability analysis. RESULTS: HALDN was technically successful in 251 patients(1 patient had to be converted to open donor nephrectomy). The operative times were increased in group II, but the differences between the groups were not statistically significant. The warm ischemic times were significantly longer in group II. The intraoperative blood loss, postoperative hospital stay and complication rate in the donor group were not associated with the number of renal arteries. The recipients' renal function and overall graft survival were similar between groups I and II. CONCLUSIONS: In our single-center study, the presence of renal artery multiplicity when performing HALDN does not have a significant impact on the outcomes of the renal donors or recipients.
