Antibacterial therapy of cholecystocholangitis in viral hepatitis

The chemotherapy of cholecystocholangitis in patients with virus hepatitis was estimated. Antibiotics, furagin and pathogenetic drugs were used for the treatment. The antibiotics were chosen with regard to their sensitivity to the bile microflora. This resulted in sanation of the bile ducts. Furagin was less effective. The use of the pathogenetic drugs alone was ineffective in the majority of patients.

Staphylococcus aureus cholecystitis: a report of three cases with review of the literature

Infection of the hepatobiliary system is most commonly due to enteric bacteria. We report three unusual cases of acute cholecystitis in which Staphylococcus aureus was the primary pathogen. Infection of the gallbladder with this organism has been rarely described and may be associated with gallstones and obstructive disease as well as acalculous cholecystitis in the setting of staphylococcal bacteremia and endocarditis. Two of our patients had multiple chronic medical conditions and were infected with oxacillin-resistant S. aureus (ORSA) suggesting nosocomial acquisition. Including our cases with a review of the literature, three of nine reports of S. aureus cholecystitis were associated with infectious endocarditis. Thus, the finding of S. aureus cholecystitis with bacteremia is rare and should prompt an investigation for a possible endovascular focus of infection.     

Biliary proteins: assessment of quantitative techniques and comparison in gallstone and nongallstone subjects

Although protein is the third most abundant solid in bile and is important in cholesterol crystal formation, methods for quantitating the concentration of total protein in bile have not been systematically evaluated. To establish a reliable protein assay for bile, we evaluated three protein assays (Lowry's method and the fluorescamine and Coomassie blue methods), and employed amino acid analysis as a reference technique. Large protein-to-protein variations were observed with the fluorescamine and Coomassie blue methods. Although all assays were affected by interfering substances, Lowry's method and the fluorescamine technique (after trichloroacetic acid precipitation and delipidation of bile) and the Coomassie blue method with native bile showed excellent correlations (P less than 0.0001) with those obtained by amino acid analysis. Using these reliable protein assays, we examined gallbladder bile obtained at surgery from subjects with and without gallstones. No differences in the concentrations of total biliary proteins were observed among patients with cholesterol (n = 23) or pigment (n = 7) gallstones and subjects without gallstones (n = 10). Protein values obtained by amino acid analysis also did not differ among groups. As expected, bile from patients with cholesterol gallstones was supersaturated with cholesterol while bile from nongallstone subjects and those with pigment stones was unsaturated. These results indicate that it is not possible to separate patients with and without gallstones on the basis of the total protein concentration of gallbladder bile.     

Diagnosis and Treatment of Xanthogranulomatous Cholecystitis: A Report of 39 Cases

This study focuses on providing diagnosis and treatment for xanthogranulomatous cholecystitis (XGC). Clinical data from 39 patients diagnosed with XGC by pathological examination between 2002 and 2010 were analyzed retrospectively. As a result, in this group of patients, the male to female ratio was 30:9 and the average age of XGC onset was 62.2?years. Clinical manifestation of the disease was similar to general cholecystitis and preoperative CT examination showed that there were only 4 XGC cases, while the others were possibly misdiagnosed. Intraoperative observations showed that all the patients had gallbladder wall thickening. This was associated with gallbladder stones in 37 patients (94.9?%), choledocholith in 11 patients (28.2?%), and Mirizzi syndrome in 5 patients (12.8?%). In this study, intraoperative frozen section pathology was conducted in 14 patients and no gallbladder cancer was found. Laparoscopic cholecystectomy was performed on 7 patients, of which two were transferred to laparotomy. Of the remaining 32 cases, 25 were subjected to open cholecystectomy, 3 to partial cholecystectomy, and 4 to the cholecystectomy and partial liver wedge resection. It was concluded that XGC is a unique type of cholecystitis with atypical clinical manifestations and is often difficult to diagnose preoperatively. Pathological examination is a key to diagnose XGC and cholecystectomy is the primary surgical treatment. In patients with choledochectasia or jaundice, for whom we cannot exclude calculus of common bile duct, common bile duct exploration should be considered. The prognosis of XGC appears to be good with the above approaches.     

Suppression of the adhesive properties of mucosal microflora by ampicillin in peptic ulcer

Persistence of mucous bacteria in the mucosa of the stomach and duodenum was studied bacteriologically and electron microscopically in 132 patients with peptic ulcer. 235 microbial strains were isolated from the mucosa and its surface in 96 per cent of the patients. 80.8 per cent of the isolates belonged to different species of Staphylococcus and Streptococcus. The other 19.2 per cent of the isolates belonged to 9 rare bacterial species. 235 antibioticograms were analysed and it was shown that the predominating part of the isolates was mainly sensitive to ampicillin. Then follow ampiox, dicloxacillin and benzylpenicillin. Ampicillin was recommended for preoperative sanation of the stomach mucosa. 30 patients were given ampicillin orally in a dose of 0.25 g 4 times a day for 3 days before operations. It was found that the drug inhibited the adhesive properties of the mucous bacteria and even killed them.     

Hepatic cholesterol metabolism in cholesterol gallstone disease

Hepatic cholesterol metabolism was examined in 27 Swedish patients with cholesterol gallstone disease and in 13 patients free of gallstones operated for roentgenographically suspect polyps in the gallbladder. All 40 patients underwent cholecystectomy, and a liver biopsy and gallbladder bile were obtained at surgery. The cholesterol saturation of gallbladder bile was significantly higher in patients with gallstones compared to the gallstone-free controls (131 +/- 13 vs. 75 +/- 5%, P less than 0.001). Microsomal 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity, governing cholesterol synthesis, did not differ between gallstone and gallstone-free patients (104 +/- 11 vs. and 109 +/- 22 pmol/min per mg protein, respectively). The activity of cholesterol 7 alpha-hydroxylase, catalyzing the catabolism of cholesterol to bile acids, was not significantly decreased in gallstone patients (6.2 +/- 1.1 vs. 8.0 +/- 2.0 pmol/min per mg protein). The capacity to esterify cholesterol, judged by the activity of acyl coenzyme A:cholesterol acyltransferase (ACAT), was similar in gallstone and gallstone-free patients (5.4 +/- 0.4 vs. 6.7 +/- 1.1 pmol/min per mg protein). In the presence of exogenous cholesterol, ACAT activity increased by more than fourfold in both groups. No correlation was found between the saturation of gallbladder bile and any of the mentioned enzyme activities in gallstone patients. It is concluded that distinct abnormalities in cholesterol metabolizing enzymes are not of major importance for development of gallstones in Swedish patients with cholesterol gallstone disease. The results support the contention that the etiology of cholesterol gallstones is multifactorial.     

Joint action of nitrofuran preparations and bile acids on bacteria of the genus Proteus]

Sensitivity of 25 fresh isolates of Proteus to some nitrofuran drugs most widely used in the clinical practice, such as furacillin, furagin, furazolidone and nitrofurantoin was studied. When the drugs were used in combination with some bile acids, i.e. desoxycholic, dehydrocholic, cholic and glycocholic acids, significant in vitro potentiation of the antibacterial activity of the nitrofurans against the isolates was observed. The combinations of the drugs with desoxycholic acid proved to be most effective. In the presence of this acid the bacteriostatic dose of the drugs decreased several thousand times. Combination of the nitrofurans with the other acids resulted in an increase in the antimicrobial activity amounting to several hundred times. The combinations of the drugs with the bile acids had not only bacteriostatic but also bactericidal effect.

目的:检测胆囊腺癌组织中白细胞介素-8(IL-8)mRNA的表达、肿瘤相关巨噬细胞(TAM)计数并探讨其临床病理意义。方法:收集中南大学湘雅二医院及湖南省人民医院近五年胆囊腺癌手术切除标本36例及慢性胆囊炎手术切除标本10例,采用原位分子杂交方法检测IL-8表达,ABC免疫组化法进行TAM计数。比较胆囊腺癌和慢性胆囊炎标本组织中IL-8 mRNA表达和TAM计数的差异,并分析其与胆囊腺癌临床病理特征之间的关系。结果:胆囊腺癌组织中IL-8 mRNA表达阳性率及其评分均明显高于慢性胆囊炎(P0.01),IL-8 mRNA表达阳性率及其评分与其侵犯胆总管及发生淋巴结转移显著相关(P0.05)。胆囊腺癌组织中TAM计数(24.89±0.84)明显高于慢性胆囊炎组织(16.19±0.66),差异有统计学意义(P0.01);侵犯胆总管、肝脏及发生淋巴结转移的胆囊腺癌组织中TAM计数高于未侵犯胆总管、肝脏及发生淋巴结转移的胆囊腺癌组织TAM计数,其中侵犯胆总管和发生淋巴结转移之间差异显著(P0.01)。IL-8 mRNA阳性病例的TAM计数均明显高于阴性病例(P0.01),TAM计数与IL-8 mRNA评分间也存在显著正相关(r=0.748,P0.001)。结论:IL-8和TAM计数与胆囊癌的发生和发展密切相关,IL-8可能在促进TAM向胆囊癌组织迁移浸润中起作用。     

Prevalence of gallstones and gallbladder disease in Canadian Micmac Indian women.

The prevalence of gallstones and gallbladder disease was studied between October 1973 and June 1976 in Canadian Micmac Indian women aged 15 to 50 years in an inland rural community near Shubenacadie, NS. Of 132 women at risk 98 underwent cholecystography, 6 had a history of cholecystectomy (verified from hospital records) and 3 had cholecystectomy because of cholecystitis during the 3 years of the study. Of the 17 abnormal cholecystograms 10 showed radiolucent gallstones, and repeated studies documented gallstones in 6 of the 7 radiographs on which the gallbladder was not visualized. The prevalence of gallstones was found to be 211/1000, and that of gallbladder disease, 240/1000. The peak prevalence was at 30 to 39 years of age. The women with gallbladder disease were significantly more obese and of greater parity than those without gallbladder disease even when age was controlled. The Micmac Indian women of Nova Scotia appear to be at a much higher risk for the development of cholesterol gallstones and gallbladder disease than Caucasian women in Framingham, Massachusetts.     

Microflora in patients with complicated forms of acute cholecystitis treated by low-frequency ultrasonics and sulfacrylate glue

Investigation of microflora in patients with complicated acute cholecystitis treated with low frequency ultrasound in combination with sulfacrylate glue showed that Staphylococcus and Escherichia played the leading role in the complication etiology. Among the nonsporulating organisms bacteroides predominated. The combined use of low frequency ultrasound and sulfacrylate glue in treatment of complicated acute cholecystitis proved to be an efficient procedure providing more rapid sanation of the purulent inflammation foci.     

成石前后胆囊粘膜上皮多聚核蛋白体RNA含量变化—胆液糖蛋白和蛋白质增加的机制探讨

胆囊淤泥是胆囊结石的前身。测定胆囊粘膜上皮游离(FPR)和结合多聚核蛋白体(MBPR)的RNA含量及胆液粘液糖蛋白(MGP)的结果表明:胆囊淤泥患者胆囊粘膜合成和分泌MGP明显亢进,MBPR与相应GB中MGP的相关性比较提示此时尚有胆液淤积存在,且FPR的RNA含量也显著增高,提示细胞增殖加快。荧光胺法测定胆液蛋白质的含量发现,胆囊淤泥和胆固醇性结石患者胆囊液GB蛋白质含量显著高于色素性结石患者及“正常”对照,但蛋白质的GB浓度与HB浓度的比值显著低于胆固醇GB/HB比值,且GB中MGP与蛋白质含量呈显著正相关。说明蛋白质含量的增加与GB中过高的MGP阻止胆囊中蛋白质的清除过程有关。成石前GB中MGP和蛋白质含量的同时增高及其机制的确立,对认识及预防体内结石均有意义。     

Cytologic diagnosis of suppurative cholecystitis due to Candida albicans and actinomyces. A report of 2 cases

BACKGROUND: Cholecystitis is a common inflammatory disease of the gallbladder. Actinomycosis and candidiasis of the gallbladder are uncommon causes of acute cholecystitis. There has been no previous report on the cytologic diagnosis of actinomycosis and candidiasis from aspirated gallbladder bile intraoperatively. CASES: Purulent bile was intraoperatively aspirated from the gallbladder of 71-year-old Indian and a 30-year-old Australian woman. The specimens were sent for cytologic examination. The first case revealed sulphur granules characteristic of Actinomyces spp. The second case showed budding spores and pseudohyphae of Candida spp. Pure colonies of Candida albicans grew from the bile culture. CONCLUSION: Actinomycosis and candidiasis rarely cause acute suppurative cholecystitis. Initial diagnosis can be made by cytologic examination of the aspirated purulent bile intraoperatively.     

Pathogenesis of human cholesterol cholelithiasis.

The pathogenesis of cholesterol cholelithiasis in humans has been studied by means of three techniques. The cholesterol-solubilizing capacity of bile may be determined by estimation of the relative composition of the three major lipid constituents of bile. Consistent reduction in the cholesterol-carrying capacity of gallbladder bile of persons with gallstones when compared with normal subjects has not been shown. Normal subjects frequently have supersaturated bile. Secretion rates of biliary lipids have been estimated by two methods; with the method that appears to be more physiologic no change in lipid secretion rates was found in gallstone patients. Bile acid pool size has been measured by isotope dilution techniques; it is reduced in patients with gallstones. It is not clear whether this reduction is important in the pathogenesis of cholesterol cholelithiasis, for the bile acid secretion rate is normal because of an increased rate of cycling of the pool through the enterohepatic circulation. The role of the gallbladder in the genesis of cholesterol cholelithiasis may be more important than has been realized.     

Pneumocystis carinii infection in a pediatric tuberculosis hospital

An outbreak of pneumocytosis in a children's tuberculosis hospital was analyzed. The infection was characterized by few signs and favourable progress. Antibiotic therapy failed. To eliminate the outbreak of pneumocystosis in the hospital it was necessary to detect all the children with pneumocystosis and carriers of pneumocysts among the patients and medical staff, to use furazolidone for etiotropic treatment of the patients with pneumocystosis and to perform one-stage sanation of the carriers with antiparasitic agents.     

Fine needle aspiration cytology in xanthogranulomatous cholecystitis, gallbladder adenocarcinoma and coexistent lesions

OBJECTIVE: To evaluate the diagnostic efficacy of fine needle aspiration cytology (FNAC) in gallbladder mass lesions and to explore the possibility of overlooking malignancy in coexistent adenocarcinoma with xanthogranulomatous cholecystitis (XGC) on fine needle aspiration smears. STUDY DESIGN: In a retrospective, seven-year study, ultrasound-guided needle aspirates from 25 histologically proven cases of gallbladder adenocarcinoma, 11 cases of gallbladder adenocarcinoma associated with XGC and 20 cases of XGC were evaluated for the presence of mesotheliumlike, foam, inflammatory and multinucleate giant cells; pink, granular background; bile; and degenerated cells, along with atypical or frankly malignant cells. Detailed clinical findings were retrieved from the records. RESULTS: The overall sensitivity of detecting carcinoma was 90.63% and specificity 94.74%. The sensitivity of detecting malignancy was 80% when adenocarcinoma was associated with XGC. CONCLUSION: FNAC plays an important role in making the preoperative diagnosis of adenocarcinoma, XGC and coexistent lesions. The probability of detecting malignancy is greater than with XGC in coexistent lesions. Thus, a preoperative FNAC diagnosis would help in determining the urgency of treatment and in planning for the surgical procedure in gallbladder lesions.     

Variation in Hepatic Bile Composition Following Cholecystectomy in Patients with Previous Gallstones

The composition of fasting hepatic bile was analyzed in 63 samples from 8 patients following cholecystectomy to determine if bile was lithogenic in patients with previous cholesterol gallstones after removal of the gallbladder. Bile specimens were obtained from t-tubes over a 7-20 day study period following re-establishment of the enterohepatic circulation. Bile composition varied on a day to day basis in each patient. 18 of 63 samples were lithogenic according to criteria of Admirand and Small while 35 of 63 samples were lithogenic according to criteria of Hegardt and Dam. Variations in the composition of hepatic bile appeared related to changes in the excretion rate of bile acids. These studies demonstrate that hepatic bile may be lithogenic after cholecystectomy and indicate that factors other than sequestration of the bile acid pool in the gallbladder influence the enterohepatic circulation of bile acids and the lithogenicity of bile.     

Feasibility of breast conservation after neoadjuvant taxene based chemotherapy in locally advanced breast cancer: a Prospective Phase I trial

Background

Acute cholecystitis can be the result of retention of bile in the gallbladder with possible secondary infection and ischaemia. The aim of the present study was to investigate whether internal drainage of the gallbladder could protect against the development of acute cholecystitis in a pig model.

Materials and methods

Twenty pigs were randomized to either internal drainage (drained) or not (undrained). Day 0 acute cholecystitis was induced by ligation of the cystic artery and duct together with inoculation of bacteria. Four days later the pigs were killed and the gallbladders were removed and histologically scored for the presence of cholecystitis. Bile and blood samples were collected for bacterial culturing and biochemical analyses.

Results

The histological examination demonstrated statistical significant differences in acute cholecystitis development between groups, the degree of inflammation being highest in undrained pigs. There were no differences in bacterial cultures between the two groups.

Conclusion

Internal drainage of the gallbladder protected against the development of acute cholecystitis in the present pig model. These findings support the theory that gallstone impaction of the cystic duct plays a crucial role as a pathogenetic mechanism in the development of acute cholecystitis and suggest that internal drainage may be a way to prevent and treat acute cholecystitis.
