Spontaneous bacterial peritonitis is one of the important complication of childhood nephrotic syndrome which occurs not infrequently but this complication in adults with nephrotic syndrome is ,however, very rare. The fact that ascites formation is more frequently seen in childhood nephrotic syndrome and that minimal change disease, the commonest pathology found in childhood is associated with impairment in both cellular and humoral immunities may be an explanation for the discrepancy. We have experienced two cases of spontaneous bacterial peritonitis complicated in adults with nephrotic syndrome. The age of patients is 23 and 68 years respectively. The serum IgG level of younger patient is markedly decreased (375 mg/dL) and that of elderly patient is lower normal limit (765 mg/dL). Peritonitis was complicated during relapse in the younger patient. Both of the patients were receiving steroid therapy before complicated by peritonitis. Both patients recovered from peritonitis by antibiotic therapy but, elderly patient died from nosocomial pneumonia.

A boy, aged 3 hours, was admitted due to a prenatal diagnosis of fetal hydrops at 3 hours after resuscitation for birth asphyxia. Prenatal examination at 5 months of gestation showed massive ascites in the fetus, and after birth, the boy had the manifestations of systemic hydroderma, massive ascites, coarse face, and hepatomegaly. Genetic testing revealed heterozygous mutations in the SLC17A5 gene, and there was a significant increase in urinary free sialic acid. Placental pathology showed extensive vacuolization in villous stromal cells, Hofbauer cells, cytotrophoblast cells, and syncytiotrophoblast cells in human placental chorionic villi. The boy was finally diagnosed with free sialic acid storage disorders (FSASDs). This is the first case of FSASDs with the initial symptom of fetal hydrops reported in China. The possibility of FSASDs should be considered for cases with non-immune hydrops fetalis, and examinations such as placental pathology and urinary free sialic acid may help with early diagnosis and clinical decision making.

The lateral margin of the psoas muscle, contrasted by retroperitoneal fat, is usually visualized o plainabdominal radiography. Failure to visualize all or segment of lateral margin of the psoas muscle, so called psoassing, has been emphasized as reliable finding of retroperitoneal pathology. But the significance of psoas sign hasbeen controversial. The authors reevaluated ‘psoas sign’ by comparing 160 abdominal radiography with CT. Theresults were as follows: 1. In 160 supine radiographys, good visualization was present in 106 cases(66.3%), faintvisualizatin in 24(15.0%), segmental nonvisualization in 18(11.3%), and completer nonvisualization in 12(7.5%). In113 erect radiographs, good visualization was present in only 36 cases(31.9%). 2. Asymmetric visualization waspresent in 84 out of 160 cases. In patient with scoliosis, lateral margin of convex side was seen more clearlythan concave side, and this finding was statistically significant (p<0.005). 3. Ascites did not directly influenceto psoa visualization contrary to common belief. 4. In 54 cases of faint or nonvisualization, normal was16(29.6%), intraperitoneal pathology was 16(29.6%), and retroperitoneal pathology was 22(40.7%). 1) In normalpatient, psoas contact with kidney or intestine and deformed psoas muscle were responsible for poor visualization. 2) The major cause of poor visualization in intraperitoneal pathology were psoas contact with displaced kidney byhepatomegaly, ascites with scanty retroperitoneal fat and derformed psaos muscle. 3) The major cause of poorvisualization in retroperitoneal pathology were psoas invasion by tumor or inflammation, psoas conntact withenlarged kidney or perirenal lesion. 5. In summary, the mechanism of faint or nonvisualization of psoas marginwere: 1) psoas contact with normal or pathologic organs 2) psoas invasion by tumor or inflammation 3) deformedpsoas muscle 4) scanty retroperitoneal fat

Sarcomatoid mesothelioma is not very common, mesothelioma is directly attributable to occupational asbestos exposure, with 90% of cases showing a history of exposure. A 66-year-old male was admitted with an abdominal pain that persisted for 3 weeks. He had no abdominal mass. Computed tomography showed soft tissue thickening in perihepatic space and nodularities in omentum and peritoneum with ascites. There was no absolute diagnosis evidence in ascites analysis. Although the pathology of ascites was free for malignancy, the patient underwent omentum biopsy for definitive diagnosis. In laproscopic exploration, there was omental cake, peritoneal nodular seeding. It was suspected cancer carcinomatosis. Immunohistochemical findings suggested that it was sarcomatoid masothelioma. This is the rare case of a peritoneal sarcomatoid mesothelioma, without any exposure to asbestos.

OBJECTIVE: To define the MRI findings of congenital high airway obstruction sequence (CHAOS) in a series of fetuses. MATERIALS AND METHODS: Prenatal fetal MR images were reviewed in seven fetuses with CHAOS at 21 to 27 weeks of gestation. The MRI findings were reviewed. The MRI parameters evaluated included the appearance of the lungs and diaphragm, presence or absence of hydrops, amount of amniotic fluid, airway appearance, predicted level of airway obstruction, and any additional findings or suspected genetic syndromes. RESULTS: All the fetuses viewed (7 of 7) demonstrated the following MRI findings: dilated airway below the level of obstruction, increased lung signal, markedly increased lung volumes with flattened or inverted hemidiaphragms, massive ascites, centrally positioned and compressed heart, as well as placentomegaly. Other frequent findings were anasarca (6 of 7) and polyhydramnios (3 of 7). MRI identified the level of obstruction as laryngeal in five cases and tracheal in two cases. In four of the patients, surgery or autopsy confirmed the MRI predicted level of obstruction. Associated abnormalities were found in 4 of 7 (genetic syndromes in 2). Postnatal radiography (n = 3) showed markedly hyperinflated lungs with inverted or flattened hemidiaphragms, strandy perihilar opacities, pneumothoraces and tracheotomy. Two fetuses were terminated and one fetus demised in utero. Four fetuses were delivered via ex utero intrapartum treatment procedure. CONCLUSION: MRI shows a consistent pattern of abnormalities in fetuses with CHAOS, accurately identifies the level of airway obstruction, and helps differentiate from other lung abnormalities such as bilateral congenital pulmonary airway malformation by demonstrating an abnormally dilated airway distal to the obstruction.

The lymphatic system is part of the circulatory system and plays a key role in normal vascular function. Its failure plays a crucial role in the development and maintenance of various diseases including liver diseases. Lymphangiogenesis (the growth of lymphatic vessels) and changes in the properties of lymphatic vessels are associated with pathogenesis of tumor metastases, ascites formation, liver fibrosis/cirrhosis and portal hypertension. Despite its significant role in liver diseases and its importance as a potential therapeutic target for those diseases, the lymphatic vascular system of the liver is poorly understood. Therefore, how the lymphatic vascular system in general and lymphangiogenesis in particular are mechanistically related to the pathogenesis and maintenance of liver diseases are largely unknown. This article summarizes: 1) the lymphatic vascular system; 2) its role in liver tumors, liver fibrosis/cirrhosis and portal hypertension; and 3) its role in ascites formation.

PURPOSE: We wished to evaluate the usefulness of helical CT for the diagnosis of strangulation of the dilated small bowels. MATERIALS AND METHODS: The CT scans of 31 patients with small bowel obstruction from various causes were reviewed retrospectively. Thirteen of these patients were confirmed as small bowel strangulation by surgery and pathology. Fourteen patients underwent surgery, but they had no strangulation. Three patients were reduced by using a nasogastric tube and one infant with intussusception was reduced by air reduction. The following CT findings of strangulation were evaluated: reduced bowel wall enhancement by visual assessment and measuring the HU, ascites, thickening of bowel wall, abnormal mesenteric vessel location and whirlpool appearance, and mesenteric venous engorgement. For the precise evaluation of reduced bowel wall enhancement, the HUs were measured by 1 mm2 of ROI, and the differences of HUs between the well enhanced bowel and poorly enhanced bowel were compared. RESULTS: For the diagnosis of strangulation, measurement of HU of the bowel wall could improve the sensitivity from 69% to 100%. The specificity of both methods, by visual assessment and measurement of HU, was 94%. Ascites had a sensitivity of 69% and specificity of 44%. Thickening of bowel wall had a sensitivity of 38% and specificity of 78%. Abnormal mesenteric vessel location and whirlpool appearance had a sensitivity of 38% and specificity of 83%. Mesenteric venous engorgement had a sensitivity of 31% and specificity of 72%. CONCLUSION:Measurement of HU of the bowel wall after contrast enhancement can be a useful method in the differential diagnosis between the strangulated and non-strangulated bowels in patients with small bowel obstruction.

PURPOSE: Recently, randomized controlled trials have reported that conservative therapy can be a treatment option in patients with noncomplicated appendicitis. However, preoperative diagnosis of noncomplicated appendicitis is difficult. In this study, we determined predictive factors to distinguish patients with noncomplicated appendicitis from those with complicated appendicitis. METHODS: A total of 351 patients who underwent surgical treatment for acute appendicitis from January 2011 to December 2012 were included in this study. We classified patients into noncomplicated or complicated appendicitis groups based on the findings of abdominal computed tomography and pathology. We performed a retrospective analysis to find factors that could be used to discriminate between noncomplicated and complicated appendicitis. RESULTS: The mean age of the patients in the complicated appendicitis group (54.5 years) was higher than that of the patients in the noncomplicated appendicitis group (40.2 years) (P < 0.001), but the male-to-female ratios were similar. In the univariate analysis, the appendicocecal junction's diameter, appendiceal maximal diameter, appendiceal wall enhancement, periappendiceal fat infiltration, ascites, abscesses, neutrophil proportion, C-reactive protein (CRP), aspartate aminotransferase, and total bilirubin were statistically significant factors. However, in the multivariate analysis, the appendiceal maximal diameter (P = 0.018; odds ratio [OR], 1.129), periappendiceal fat infiltration (P = 0.025; OR, 5.778), ascites (P = 0.038; OR, 2.902), and CRP (P < 0.001; OR, 1.368) were statistically significant. CONCLUSION: Several factors can be used to distinguish between noncomplicated and complicated appendicitis. Using these factors, we could more accurately distinguish patients with noncomplicated appendicitis from those with complicated appendicitis.
